Description

发射功率压缩方法和终端设备Transmitting power compression method and terminal device

技术领域Technical field

本发明实施例涉及通信技术，尤其涉及一种发射功率压缩方法和终端设备。The embodiments of the present invention relate to communications technologies, and in particular, to a transmit power compression method and a terminal device.

背景技术Background technique

在通用移动通信***(Universal Mobile Telecommunications System，简称：UMTS)中，基站可以为终端设备配置两个载波，以使得终端设备可以使用该两个载波同时发送数据。目前，上述终端设备在使用该两个载波发送数据时，会为每个载波配置不同的信道资源，并基于终端设备所传输的业务量，为每个载波设置相应的发射功率。In a Universal Mobile Telecommunications System (UMTS), a base station can configure two carriers for a terminal device, so that the terminal device can simultaneously transmit data using the two carriers. At present, when the terminal device uses the two carriers to transmit data, different channel resources are configured for each carrier, and corresponding transmission power is set for each carrier based on the traffic volume transmitted by the terminal device.

考虑到终端设备的功耗，上述终端设备的总发射功率(即终端设备为上述两个载波设置的发射功率之和)需要小于或等于最大允许发射功率，该最大允许发射功率为该终端设备功率等级决定的最大发射功率和由***设定的最大发射功率两者之间的最小值。因此，现有技术中，若终端设备的总发射功率大于最大允许发射功率，终端设备会优先选择专用物理控制信道(Dedicated Physical Control Channel，简称：DPCCH)功率较高的载波，将该载波的增强型专用物理数据信道(Enhanced Dedicated Physical Data Channel，简称：E-DPDCH)的发射功率进行压缩，以使终端设备的总发射功率小于或等于最大允许发射功率，从而使终端设备可以使用该两个载波同时发送数据。Considering the power consumption of the terminal device, the total transmit power of the terminal device (that is, the sum of the transmit powers set by the terminal device for the two carriers) needs to be less than or equal to the maximum allowed transmit power, and the maximum allowable transmit power is the power of the terminal device. The minimum value between the maximum transmit power determined by the level and the maximum transmit power set by the system. Therefore, in the prior art, if the total transmit power of the terminal device is greater than the maximum allowable transmit power, the terminal device preferentially selects a carrier with a higher power of a Dedicated Physical Control Channel (DPCCH), and enhances the carrier. The transmit power of the Enhanced Dedicated Physical Data Channel (E-DPDCH) is compressed so that the total transmit power of the terminal device is less than or equal to the maximum allowable transmit power, so that the terminal device can use the two carriers. Send data at the same time.

然而，终端设备在通过优先压缩DPCCH功率较高的载波的发射功率，以实现终端设备的总发射功率小于或等于最大允许发射功率时，发射功率压缩效果不佳，无法满足实际使用时的需求。However, when the terminal device preferentially compresses the transmit power of the carrier with a higher DPCCH power to achieve that the total transmit power of the terminal device is less than or equal to the maximum allowable transmit power, the transmit power compression effect is not good, and the actual use requirement cannot be met.

The first carrier compresses the transmit power of the first channel of the first carrier to achieve the purpose of compressing the first total transmit power of the terminal device. Since the transmit power of the first carrier is the largest, the transmit power of the first carrier can be greatly compressed by preferentially compressing the transmit power of the first channel of the first carrier having the largest transmit power, thereby greatly compressing the terminal device. The first total transmit power is such that after the terminal device compresses the transmit power of the first channel of the first carrier, the first total transmit power after the terminal device is compressed is less than or equal to the maximum allowable transmit power of the terminal device.

The first total transmit power is such that after the terminal device compresses the transmit power of the first channel of the first carrier, the first total transmit power after the terminal device is compressed is less than or equal to the maximum allowable transmit power of the terminal device. The compression effect of the transmission power is improved, and the efficiency of transmitting data by the terminal device is also improved.

UMTS***引入高速上行分组接入(HSUPA，High Speed Uplink Packet Access)技术，使得终端设备发送上行数据所使用的载波上，除了可以配置专用物理数据信道(Dedicated Physical Data Channel，简称：DPDCH)、专用物理控制信道(Dedicated Physical Control Channel，简称：DPCCH)、高速专用物理控制信道(High Speed Dedicated Physical Control Channel，简称：HS-DPCCH)等物理信道之外，还可以配置增强型专用物理数据信道(Enhanced Dedicated Physical Data Channel，简称：E-DPDCH)和增强型专用物理控制信道(Enhanced Dedicated Physical Control Channel，简称：E-DPCCH)等物理信道，通过这种方式，可以提高终端设备的上行吞吐量。The UMTS system introduces the High Speed Uplink Packet Access (HSUPA) technology, so that the carrier can use the dedicated physical data channel (DPDCH) for dedicated transmission of the uplink data. In addition to physical channels such as the Dedicated Physical Control Channel (DPCCH) and the High Speed Dedicated Physical Control Channel (HS-DPCCH), an enhanced dedicated physical data channel (Enhanced) can also be configured. The physical channel such as the Dedicated Physical Data Channel (E-DPDCH) and the Enhanced Dedicated Physical Control Channel (E-DPCCH) can improve the uplink throughput of the terminal device.

当终端设备通过上述HSUPA技术使用两个载波(例如：载波1和载波2)发送上行数据时，该两个载波允许配置的最大信道数量例如可以如下述表1、表2、表3中任一表格所示：When the terminal device transmits uplink data by using the two carriers (for example, carrier 1 and carrier 2) by using the above HSUPA technology, the maximum number of channels allowed to be configured by the two carriers may be, for example, any one of the following Table 1, Table 2, and Table 3. The table shows:

载波2Carrier 2	00	00	44	11	11

终端设备在使用上述表1-表3中任一表格配置的载波1和载波2进行通信时，会为载波1和载波2的每个信道设置一定的发射功率，具体地，终端设备会为每个载波的DPCCH设置一定的发射功率，以及为该载波的每个信道设置一个增益因子，该载波上的其他信道与该载波的DPCCH的功率之比等于该信道的增益因子与DPCCH的增益因子比值的平方，其中，DPCCH对应的增益因子可以为1。上述载波1的每个信道的发射功率与载波2的每个信道的发射功率之和，即为终端设备的总发射功率。When the terminal device communicates with carrier 1 and carrier 2 configured in any of the above Tables 1 to 3, a certain transmission power is set for each channel of carrier 1 and carrier 2, specifically, the terminal device will be each The DPCCH of each carrier sets a certain transmit power, and sets a gain factor for each channel of the carrier. The ratio of the power of other channels on the carrier to the power of the DPCCH of the carrier is equal to the gain factor of the channel and the gain factor ratio of the DPCCH. The square of the square, where the gain factor corresponding to the DPCCH can be 1. The sum of the transmission power of each channel of the carrier 1 and the transmission power of each channel of the carrier 2 is the total transmission power of the terminal device.

目前，3GPP的相关协议规定了终端设备的最大允许发射功率，该终端设备的最大允许发射功率为：终端设备的功率等级所对应的最大发射功率和***设置的上行最大发射功率之间的最小值，因此，终端设备在使用上述载波1和载波2发送上行数据时，终端设备的总发射功率需要小于或等于该最大允许发射功率。现有技术中，若上述终端设备的总发射功率大于终端设备的最大允许发射功率，则终端设备会优先选择一个DPCCH的发射功率较高的载波，将该载波的E-DPDCH的发射功率进行压缩。At present, the relevant protocol of the 3GPP specifies the maximum allowed transmit power of the terminal device, and the maximum allowable transmit power of the terminal device is: the minimum between the maximum transmit power corresponding to the power level of the terminal device and the maximum transmit power set by the system. Therefore, when the terminal device transmits the uplink data by using the carrier 1 and the carrier 2, the total transmission power of the terminal device needs to be less than or equal to the maximum allowed transmission power. In the prior art, if the total transmit power of the terminal device is greater than the maximum allowable transmit power of the terminal device, the terminal device preferentially selects a carrier with a higher transmit power of the DPCCH, and compresses the transmit power of the E-DPDCH of the carrier. .

以载波2的DPCCH的发射功率较高为例，则终端设备在确定终端设备的总发射功率大于终端设备的最大允许发射功率时，终端设备会先压缩载波2的E-DPDCH的发射功率，以压缩终端设备的总发射功率。若终端设备压缩后的总发射功率小于或等于终端设备的最大允许发射功率，则载波1和载波2的各信道可以采用该压缩后的发射功率发送数据。然而，虽然上述载波2的DPCCH发射功率大于载波1的DPCCH发射功率，但是载波2的发射功率 (即载波2的所有信道的发射功率之和)不一定大于载波1的发射功率，也就是说，载波2的E-DPDCH的发射功率不一定大于载波1的E-DPDCH的发射功率。这样，终端设备在压缩载波2的E-DPDCH的发射功率时，易使终端设备的总发射功率被压缩的幅度较小，即发射功率压缩效果不佳，使得压缩后的总发射功率仍然大于终端设备的最大允许发射功率的概率较高，无法满足实际使用时的需求。Taking the higher transmit power of the DPCCH of the carrier 2 as an example, when the terminal device determines that the total transmit power of the terminal device is greater than the maximum allowable transmit power of the terminal device, the terminal device first compresses the transmit power of the E-DPDCH of the carrier 2 to The total transmit power of the terminal device is compressed. If the total transmit power of the terminal device after compression is less than or equal to the maximum allowed transmit power of the terminal device, each channel of the carrier 1 and the carrier 2 may transmit data by using the compressed transmit power. However, although the DPCCH transmission power of the above carrier 2 is greater than the DPCCH transmission power of the carrier 1, the transmission power of the carrier 2 (ie, the sum of the transmit powers of all channels of carrier 2) is not necessarily greater than the transmit power of carrier 1, that is, the transmit power of the E-DPDCH of carrier 2 is not necessarily greater than the transmit power of the E-DPDCH of carrier 1. In this way, when the terminal device compresses the transmit power of the E-DPDCH of the carrier 2, the total transmit power of the terminal device is compressed to a small extent, that is, the transmit power compression effect is not good, so that the total transmit power after compression is still greater than the terminal. The probability of the maximum allowable transmit power of the device is high, which cannot meet the requirements in actual use.

本发明实施例所涉及的发射功率压缩方法，旨在解决现有技术中终端设备在通过优先压缩DPCCH功率较高的载波的发射功率，以实现终端设备的总发射功率小于或等于最大允许发射功率时，发射功率压缩效果不佳，无法满足实际使用时的需求的技术问题。A method for compressing a transmit power according to an embodiment of the present invention is to solve the problem that a terminal device in a prior art compresses a transmit power of a carrier having a higher power of DPCCH, so that a total transmit power of the terminal device is less than or equal to a maximum allowable transmit power. At the time, the transmission power compression effect is not good, and the technical problem of the actual use requirement cannot be satisfied.

需要说明的是，本发明实施例所提供的发射功率压缩方法，包括但不限于以上UMTS***的应用场景，只要涉及终端设备需要压缩发射功率，以达到终端设备的总发射功率小于或等于最大允许发射功率的所有场景，均可以采用本发明实施例所提供的发射功率压缩方法。It should be noted that the method for compressing the transmit power provided by the embodiment of the present invention includes, but is not limited to, the application scenario of the foregoing UMTS system, as long as the terminal device needs to compress the transmit power, so that the total transmit power of the terminal device is less than or equal to the maximum allowable. The transmit power compression method provided by the embodiment of the present invention may be used in all scenarios of the transmit power.

为了便于对本发明实施例的理解，下面以具体地实施例对本发明的技术方案以及本发明的技术方案如何解决上述技术问题进行详细说明。下面这几个具体的实施例可以相互结合，对于相同或相似的概念或过程可能在某些实施例中不再赘述。In order to facilitate the understanding of the embodiments of the present invention, the technical solutions of the present invention and the technical solutions of the present invention are described in detail with reference to specific embodiments. The following specific embodiments may be combined with each other, and the same or similar concepts or processes may not be described in some embodiments.

图1为本发明实施例提供的发射功率压缩方法实施例一的流程示意图。在本实施例中，上述终端可以使用多个载波发送数据，本实施例一涉及的是终端设备通过优先压缩发射功率最大的载波的发射功率，以降低终端设备的总发射功率的具体过程。如图1所示，该方法包括：FIG. 1 is a schematic flowchart diagram of Embodiment 1 of a method for compressing a transmit power according to an embodiment of the present invention. In this embodiment, the terminal may use multiple carriers to transmit data. The first embodiment relates to a specific process in which the terminal device reduces the total transmit power of the terminal device by preferentially compressing the transmit power of the carrier with the highest transmit power. As shown in Figure 1, the method includes:

S101、若终端设备的第一总发射功率大于终端设备的最大允许发射功率，则终端设备从多个载波中确定第一载波；其中，第一总发射功率为终端设备为各载波设置的发射功率之和；第一载波为多个载波中发射功率最大的载波。S101. If the first total transmit power of the terminal device is greater than the maximum allowable transmit power of the terminal device, the terminal device determines the first carrier from the multiple carriers, where the first total transmit power is the transmit power set by the terminal device for each carrier. The sum of the first carrier is the carrier with the highest transmit power among the multiple carriers.

具体的，在本实施例中，上述终端设备可以使用多个载波发送上行数据，该多个载波可以为工作在相同频点的载波，也可以为工作在不同频点的载波。其中，上述终端设备所使用的多个载波中的每个载波均配置有至少一个用于传输终端设备的数据业务的第一信道，该第一信道例如可以为上述所说的E-DPDCH等。Specifically, in this embodiment, the terminal device may send uplink data by using multiple carriers, where the multiple carriers may be carriers operating at the same frequency point, or may be carriers operating at different frequency points. Each of the plurality of carriers used by the terminal device is configured with at least one first channel for transmitting data services of the terminal device, and the first channel may be, for example, the foregoing Said E-DPDCH and so on.

上述终端设备在使用该多个载波发送上行数据时，会为每个载波的每个信道设置一定的发射功率。具体地，终端设备会为每个载波的DPCCH设置一定的发射功率，为该载波的每个信道设置一个增益因子，该载波上的其他各信道与该载波的DPCCH的功率之比等于该信道的增益因子与DPCCH的增益因子比值的平方，其中，DPCCH对应的增益因子可以为1。每个载波的所有信道的发射功率之和为每个载波的发射功率，所有载波的发射功率之和即为终端设备的第一总发射功率。在本实施例中，若该第一总发射功率大于终端设备的最大允许发射功率，则终端设备会从多个载波中确定出一个发射功率最大的载波。When the terminal device uses the multiple carriers to transmit uplink data, a certain transmit power is set for each channel of each carrier. Specifically, the terminal device sets a certain transmit power for the DPCCH of each carrier, and sets a gain factor for each channel of the carrier, and the ratio of the power of the other channels on the carrier to the DPCCH of the carrier is equal to the channel. The gain factor is the square of the gain factor ratio of the DPCCH, where the gain factor corresponding to the DPCCH can be one. The sum of the transmit powers of all the channels of each carrier is the transmit power of each carrier, and the sum of the transmit powers of all the carriers is the first total transmit power of the terminal device. In this embodiment, if the first total transmit power is greater than the maximum allowed transmit power of the terminal device, the terminal device determines a carrier with the largest transmit power from the plurality of carriers.

S102、终端设备对第一载波的第一信道的增益因子进行压缩。S102. The terminal device compresses a gain factor of the first channel of the first carrier.

具体的，上述终端设备从多个载波中确定出第一载波之后，就可以使用功率压缩因子，对第一载波的第一信道的发射功率所对应的增益因子进行压缩。由于第一信道的发射功率与该载波的DPCCH的功率之比等于该信道的增益因子与DPCCH的增益因子比值的平方，因此，通过压缩第一信道的增益因子，达到了压缩第一载波的第一信道的发射功率的目的，进而达到压缩终端设备的第一总发射功率的目的。其中，上述终端设备如何使用功率压缩因子，对第一载波的第一信道的发射功率所对应的增益因子进行压缩具体可以参见现有技术，本发明对此不再赘述。Specifically, after the terminal device determines the first carrier from the multiple carriers, the power compression factor may be used to compress the gain factor corresponding to the transmit power of the first channel of the first carrier. Since the ratio of the transmit power of the first channel to the power of the DPCCH of the carrier is equal to the square of the gain factor of the channel and the gain factor of the DPCCH, the first carrier is compressed by compressing the gain factor of the first channel. The purpose of the transmission power of one channel is to achieve the purpose of compressing the first total transmission power of the terminal device. For example, how to use the power compression factor to compress the gain factor corresponding to the transmit power of the first channel of the first carrier may be referred to the prior art, and the details are not described herein.

本发明实施例提供的发射功率压缩方法，在终端设备的第一总发射功率大于终端设备的最大允许发射功率时，终端设备可以从终端设备所使用的多个载波中确定出一个发射功率最大的第一载波，并对该第一载波的第一信道的发射功率进行压缩，以达到压缩终端设备的第一总发射功率的目的。由于第一载波的发射功率最大，因此，通过优先压缩发射功率最大的第一载波的第一信道的发射功率，可以大幅度的压缩第一载波的发射功率，进而可以大幅度的压缩终端设备的第一总发射功率，以使得终端设备在压缩完第一载波的第一信道的发射功率之后，使终端设备压缩后的第一总发射功率小于或等于终端设备的最大允许发射功率的概率较高，提高了发射功率的压缩效果，也提高了终端设备发送数据的效率。In the transmit power compression method provided by the embodiment of the present invention, when the first total transmit power of the terminal device is greater than the maximum allowable transmit power of the terminal device, the terminal device may determine, from the multiple carriers used by the terminal device, a transmit power that is the largest. The first carrier compresses the transmit power of the first channel of the first carrier to achieve the purpose of compressing the first total transmit power of the terminal device. Since the transmit power of the first carrier is the largest, the transmit power of the first carrier can be greatly compressed by preferentially compressing the transmit power of the first channel of the first carrier having the largest transmit power, thereby greatly compressing the terminal device. The first total transmit power is such that after the terminal device compresses the transmit power of the first channel of the first carrier, the first total transmit power after the terminal device is compressed is less than or equal to the maximum allowable transmit power of the terminal device. The compression effect of the transmission power is improved, and the efficiency of transmitting data by the terminal device is also improved.

进一步地，在上述实施例的基础上，本实施例二涉及的是上述终端设备如何从多个载波中确定第一载波的具体过程，则上述S101可以包括：终端设备根据每个载波的功率信息，从多个载波中确定第一载波。Further, based on the foregoing embodiment, the second embodiment relates to the foregoing terminal device. The foregoing S101 may include: determining, by the terminal device, the first carrier from the multiple carriers according to the power information of each carrier, where the specific process of determining the first carrier from the multiple carriers is performed.

具体的，上述每个载波的功率信息可以包括如下任一个：每个载波工作的频点、每个载波的第一信道的传输时间间隔(Transmission Time Interval，简称：TTI)长度、每个载波所占用的发射功率、网络设备为每个载波分配的授权等。Specifically, the power information of each carrier may include any one of the following: a frequency point at which each carrier operates, a transmission time interval (TTI) length of the first channel of each carrier, and each carrier The occupied transmit power, the authorization assigned by the network device to each carrier, and the like.

可选的，若上述终端设备所使用的多个载波为工作在不同频点的载波，则上述终端设备可以根据每个载波的频点，从多个载波中确定第一载波，具体地：由于频点越高的载波发送数据时的路损越大，所以终端设备在设置发射功率时，会为工作在高频点的载波设置更多的发射功率，即，频点最高的载波发射功率最大。因此，上述终端设备根据每个载波所在的频点，可以将频点最高的载波作为发射功率最高的第一载波，以使得终端设备在优先压缩该第一载波的第一信道的发射功率时，可以达到大幅度的压缩第一载波的发射功率的目的，进而可以达到大幅度的压缩终端设备的第一总发射功率的目的，使终端设备压缩后的第一总发射功率小于或等于终端设备的最大允许发射功率的概率较高。Optionally, if the multiple carriers used by the terminal device are carriers that work at different frequency points, the terminal device may determine the first carrier from multiple carriers according to the frequency of each carrier, specifically: The higher the frequency point, the larger the path loss when the carrier transmits data. Therefore, when setting the transmit power, the terminal device sets more transmit power for the carrier operating at the high frequency point, that is, the carrier transmit power with the highest frequency is the largest. . Therefore, the terminal device can use the carrier with the highest frequency as the first carrier with the highest transmission power according to the frequency of each carrier, so that the terminal device preferentially compresses the transmit power of the first channel of the first carrier. The purpose of compressing the transmit power of the first carrier can be greatly achieved, and the purpose of compressing the first total transmit power of the terminal device can be achieved, so that the first total transmit power after compression by the terminal device is less than or equal to that of the terminal device. The probability of maximum allowable transmit power is high.

可选的，若上述每个载波的功率信息为每个载波的第一信道的TTI长度，则上述终端设备可以根据每个载波的第一信道的TTI长度，从多个载波中确定第一载波，具体地：在其他条件相同的情况下，在一个TTI长度内，长TTI的信道上数据使用的总功率比短TTI的要大，因此，上述终端设备根据每个载波的第一信道的TTI长度，可以将第一信道的TTI长度最大的载波作为发射功率最高的第一载波，以使得终端设备在优先压缩该第一载波的第一信道的发射功率时，可以达到大幅度的压缩第一载波的发射功率的目的，进而可以达到大幅度的压缩终端设备的第一总发射功率的目的，使终端设备压缩后的第一总发射功率小于或等于终端设备的最大允许发射功率。同时由于压缩长TTI的信道的功率对传输性能的影响要比压缩短TTI的信道的功率的影响要小，因此，优先压缩第一载波的第一信道的发射功率，还可以降低功率压缩对传输质量带来的影响。Optionally, if the power information of each carrier is the TTI length of the first channel of each carrier, the terminal device may determine the first carrier from the multiple carriers according to the TTI length of the first channel of each carrier. Specifically, under the same conditions, the total power used by the data on the channel of the long TTI is larger than the short TTI within one TTI length. Therefore, the foregoing terminal device is based on the TTI of the first channel of each carrier. The carrier with the largest TTI length of the first channel can be used as the first carrier with the highest transmit power, so that the terminal device can achieve a large compression first when preferentially compressing the transmit power of the first channel of the first carrier. The purpose of the transmit power of the carrier can further achieve the purpose of substantially compressing the first total transmit power of the terminal device, so that the first total transmit power after the terminal device is compressed is less than or equal to the maximum allowable transmit power of the terminal device. At the same time, since the power of the channel compressing the long TTI has less influence on the transmission performance than the power of the channel compressing the short TTI, the transmission power of the first channel of the first carrier is preferentially compressed, and the power compression transmission can also be reduced. The impact of quality.

可选的，若上述每个载波的功率信息为每个载波所占用的发射功率(该每个载波所占用的发射功率是指该载波的所有信道所占用的发射功率)，则上述终端设备可以根据每个载波所占用的发射功率，从多个载波中确定第一载波，具体地：上述终端设备在使用上述多个载波中的每个载波发送数据时，会为每个载波的每个信道设置一定的发射功率，使得每个载波占用一定的发射功率(即该载波的所有信道的发射功率之和)，当终端设备为某一载波的每个信道设置的发射功率越大时，该载波所占用的发射功率越大，因此，上述终端可以根据每个载波所占用的发射功率，可以将占用发射功率最大的载波作为发射功率最高的第一载波，以使得终端设备在优先压缩该第一载波的第一信道的发射功率时，可以达到大幅度的压缩第一载波的发射功率的目的，进而可以达到大幅度的压缩终端设备的第一总发射功率的目的，使终端设备压缩后的第一总发射功率小于或等于终端设备的最大允许发射功率的概率较高。Optionally, if the power information of each carrier is the transmit power occupied by each carrier (the transmit power occupied by each carrier refers to the transmit power occupied by all channels of the carrier), The terminal device may determine the first carrier from the multiple carriers according to the transmit power occupied by each carrier. Specifically, when the terminal device sends data using each of the multiple carriers, the carrier device may be used for each carrier. Each channel sets a certain transmit power, such that each carrier occupies a certain transmit power (ie, the sum of the transmit powers of all channels of the carrier), and the greater the transmit power set by the terminal device for each channel of a certain carrier The higher the transmission power of the carrier, the terminal can use the carrier with the highest transmit power as the first carrier with the highest transmit power, so that the terminal device is prioritized according to the transmit power occupied by each carrier. When the transmit power of the first channel of the first carrier is compressed, the purpose of compressing the transmit power of the first carrier can be greatly achieved, thereby achieving the purpose of substantially compressing the first total transmit power of the terminal device, so that the terminal device is enabled. The probability that the compressed first total transmit power is less than or equal to the maximum allowed transmit power of the terminal device is higher.

可选的，若上述每个载波的功率信息为网络设备为每个载波分配的授权，上述终端设备可以根据网络设备为每个载波分配的授权，从多个载波中确定第一载波，具体地：上述终端设备会根据网络设备为每个载波分配的授权，为每个载波上的信道设置发射功率。载波对应的授权越大，终端设备为该载波可设置的发射功率就越高，因此，上述终端设备根据网络设备为每个载波分配的授权，可以将授权最大的载波作为发射功率最高的第一载波，以使得终端设备在优先压缩该第一载波的第一信道的发射功率时，可以达到大幅度的压缩第一载波的发射功率的目的，进而可以达到大幅度的压缩终端设备的第一总发射功率的目的，使终端设备压缩后的第一总发射功率小于或等于终端设备的最大允许发射功率的概率较高。Optionally, if the power information of each carrier is an authorization allocated by the network device for each carrier, the terminal device may determine the first carrier from multiple carriers according to the authorization allocated by the network device for each carrier, specifically The above terminal device sets the transmission power for the channel on each carrier according to the authorization allocated by the network device for each carrier. The greater the authorization corresponding to the carrier, the higher the transmit power that the terminal device can set for the carrier. Therefore, the terminal device can use the highest authorized carrier as the highest transmit power according to the authorization allocated by the network device for each carrier. a carrier, so that the terminal device can achieve a large compression of the transmit power of the first carrier when the transmit power of the first channel of the first carrier is preferentially compressed, thereby achieving a large total compression of the terminal device. For the purpose of transmitting power, the probability that the first total transmit power after the terminal device is compressed is less than or equal to the maximum allowable transmit power of the terminal device is high.

本发明实施例提供的发射功率压缩方法，在终端设备的第一总发射功率大于终端设备的最大允许发射功率时，终端设备可以根据其所使用的多个载波中的每个载波的功率信息，从该多个载波中确定出一个发射功率最大的第一载波，并对第一载波的第一信道的发射功率进行压缩，以达到压缩终端设备的第一总发射功率的目的。由于第一载波的发射功率最大，因此，通过优先压缩发射功率最大的第一载波的第一信道的发射功率，可以大幅度的压缩第一载波的发射功率，进而可以大幅度的压缩终端设备的第一总发射功率，以使得终端设备在压缩完第一载波的第一信道的发射功率之后，使终端设备压缩后的第一总发射功率小于或等于终端设备的最大允许发射功率的概率较高，提高了发射功率的压缩效果，也提高了终端设备发送数据的效率。The transmit power compression method provided by the embodiment of the present invention, when the first total transmit power of the terminal device is greater than the maximum allowable transmit power of the terminal device, the terminal device may use the power information of each of the multiple carriers used by the terminal device, Determining a first carrier with the largest transmit power from the plurality of carriers, and compressing the transmit power of the first channel of the first carrier to achieve the purpose of compressing the first total transmit power of the terminal device. Since the transmit power of the first carrier is the largest, the transmit power of the first carrier can be greatly compressed by preferentially compressing the transmit power of the first channel of the first carrier having the largest transmit power, thereby greatly compressing the terminal device. The first total transmit power is such that after the terminal device compresses the transmit power of the first channel of the first carrier, the first total transmit power after the terminal device is compressed is less than or equal to the maximum allowable transmit power of the terminal device. High, the compression effect of the transmission power is improved, and the efficiency of transmitting data by the terminal device is also improved.

图2为本发明实施例提供的发射功率压缩方法实施例三的流程示意图。本实施例三涉及的是终端设备在压缩完第一载波的第一信道的发射功率之后，在终端设备的第二总发射功率仍然大于终端设备的最大允许发射功率时，终端设备从未执行功率压缩的载波中确定第二载波，并对该第二载波的发射功率进行压缩的具体过程。其中，上述终端设备的第二总发射功率为第一载波压缩后的发射功率与其他未被压缩的载波的发射功率之和。如图2所示，则在上述S102之后，该方法还可以包括：FIG. 2 is a schematic flowchart diagram of Embodiment 3 of a method for compressing a transmit power according to an embodiment of the present invention. The third embodiment relates to that after the terminal device compresses the transmit power of the first channel of the first carrier, when the second total transmit power of the terminal device is still greater than the maximum allowable transmit power of the terminal device, the terminal device never performs power. A specific process of determining a second carrier in the compressed carrier and compressing the transmit power of the second carrier. The second total transmit power of the terminal device is the sum of the transmit power of the first carrier compressed and the transmit power of other uncompressed carriers. As shown in FIG. 2, after the foregoing S102, the method may further include:

S201、若终端设备的第二总发射功率大于终端设备的最大允许发射功率，则终端设备从未执行功率压缩的载波中确定第二载波。S201. If the second total transmit power of the terminal device is greater than the maximum allowed transmit power of the terminal device, the terminal device determines the second carrier from the carrier that does not perform power compression.

具体的，当上述终端设备对第一载波的第一信道的发射功率压缩之后，若第一载波压缩后的发射功率与其他未被压缩的载波的发射功率之和(即上述终端设备的第二总发射功率)仍然大于终端设备的最大允许发射功率，则终端设备可以进一步地从除已被压缩发射功率的第一载波之外的其他载波中，即从未执行功率压缩的载波中再确定出一个第二载波。其中，本实施例不限定上述终端设备从未执行功率压缩的载波中确定第二载波的具体实现方式，例如：上述终端设备可以采用本实施例二所示的方式，从未执行功率压缩的载波中确定第二载波，还可以采用现有的方式，例如根据每个未执行功率压缩的载波的DPCCH的发射功率，从未执行功率压缩的载波中确定一个第二载波等。Specifically, after the terminal device compresses the transmit power of the first channel of the first carrier, if the transmit power of the first carrier is compressed and the transmit power of the other uncompressed carrier (ie, the second of the terminal device) The total transmit power) is still greater than the maximum allowed transmit power of the terminal device, and the terminal device can further determine from other carriers than the first carrier that has been compressed transmit power, ie, the carrier that has never performed power compression. A second carrier. The embodiment does not limit the specific implementation manner in which the terminal device determines the second carrier from the carrier that does not perform power compression. For example, the terminal device may adopt the manner shown in the second embodiment, and the carrier that performs power compression is never performed. The determining of the second carrier may also be performed in an existing manner, for example, determining a second carrier or the like from the carrier that does not perform power compression according to the transmit power of the DPCCH of each carrier that does not perform power compression.

S202、终端设备对第二载波的第一信道的增益因子进行压缩，直至终端设备的第二总发射功率小于或等于最大允许发射功率。S202. The terminal device compresses a gain factor of the first channel of the second carrier until the second total transmit power of the terminal device is less than or equal to the maximum allowed transmit power.

具体的，上述终端设备在从未执行功率压缩的载波中确定出第二载波之后，就可以使用功率压缩因子，对第二载波的第一信道的增益因子进行压缩，以压缩第二载波的第一信道的发射功率。其中，上述终端设备如何使用功率压缩因子，对第二载波的第一信道的发射功率所对应的增益因子进行压缩具体可以参见现有技术，本发明对此不再赘述。Specifically, after the terminal device determines the second carrier from the carrier that does not perform power compression, the power compression factor may be used to compress the gain factor of the first channel of the second carrier to compress the second carrier. The transmit power of a channel. For example, how to use the power compression factor to compress the gain factor corresponding to the transmit power of the first channel of the second carrier is not mentioned in the prior art.

在上述终端设备在压缩该第二载波的发射功率之后，若终端设备当前的第二总发射功率(即各第一载波(包括第一载波和第二载波)压缩后的发射功率和其他未被压缩的载波的发射功率之和)小于或等于最大允许发射功率，则终端设备就可以使用该多个载波，通过该当前的第二总发射功率发送数据。若终端设备当前的第二总发射功率仍然大于最大允许发射功率，则终端设备可以进一步地再从除已被压缩发射功率的第一载波和第二载波之外的其他载波中，即从未执行功率压缩的载波中再确定出一个第二载波，并对该第二载波的第一信道的发射功率进行压缩，以此循环，直至终端设备的第二总发射功率(即各第一载波压缩后的发射功率和其他未被压缩的载波的发射功率之和)小于或等于最大允许发射功率，从而使得终端设备可以使用该多个载波发送数据。After the terminal device compresses the transmit power of the second carrier, if the second total transmit power of the terminal device (ie, the transmit power of each first carrier (including the first carrier and the second carrier) is compressed and the other is not The sum of the transmitted power of the compressed carrier is less than or equal to the maximum allowed transmission For power, the terminal device can use the multiple carriers to transmit data through the current second total transmit power. If the current second total transmit power of the terminal device is still greater than the maximum allowed transmit power, the terminal device may further re-execute from other carriers than the first carrier and the second carrier that have been compressed transmit power, ie, never executed. A second carrier is further determined in the power compressed carrier, and the transmit power of the first channel of the second carrier is compressed, and is cycled until the second total transmit power of the terminal device (ie, after the first carrier is compressed) The sum of the transmit power and the transmit power of the other uncompressed carriers is less than or equal to the maximum allowable transmit power, so that the terminal device can transmit data using the plurality of carriers.

示例性的，假定终端设备当前可以使用4个载波发送数据，分别为载波1、载波2、载波3和载波4。其中，载波2的发射功率大于载波4的发射功率，载波4的发射功率大于载波3的发射功率，载波3的发射功率大于载波1的发射功率，则若终端设备为该4个载波设置的发射功率之和(即第一总发射功率)大于最大允许发射功率时，终端设备可以从该4个载波中，将发射功率最大的载波2作为第一载波，并对载波2的第一信道的发射功率进行压缩。Exemplarily, it is assumed that the terminal device can currently transmit data using 4 carriers, which are carrier 1, carrier 2, carrier 3, and carrier 4. The transmit power of the carrier 2 is greater than the transmit power of the carrier 4, the transmit power of the carrier 4 is greater than the transmit power of the carrier 3, and the transmit power of the carrier 3 is greater than the transmit power of the carrier 1, if the terminal device sets the transmit for the four carriers. When the sum of the powers (ie, the first total transmit power) is greater than the maximum allowable transmit power, the terminal device may use the carrier 2 with the largest transmit power as the first carrier and transmit the first channel of the carrier 2 from the four carriers. The power is compressed.

若压缩完载波2的第一信道的发射功率之后，终端设备的第二总发射功率(即载波2压缩后的发射功率，与，载波1、载波3、载波4的发射功率之和)仍然大于最大允许发射功率，则终端设备可以从载波1、载波3和载波4中再确定一个发射功率最大的载波作为第二载波，在本示例中，该第二载波即为载波4，即终端设备可以对载波4的第一信道的发射功率进行压缩。If the transmit power of the first channel of the carrier 2 is compressed, the second total transmit power of the terminal device (ie, the sum of the transmit power of the carrier 2 and the transmit power of the carrier 1, the carrier 3, and the carrier 4) is still greater than The maximum allowed transmit power, the terminal device may determine a carrier with the highest transmit power from the carrier 1, the carrier 3, and the carrier 4 as the second carrier. In this example, the second carrier is the carrier 4, that is, the terminal device may The transmit power of the first channel of carrier 4 is compressed.

若压缩完载波4的第一信道的发射功率之后，终端设备的第二总发射功率(即载波2压缩后的发射功率、载波4压缩后的发射功率，与，载波1、载波3的发射功率之和)小于或等于最大允许发射功率，则终端设备可以使用该4个载波，通过该终端设备的第二总发射功率发送数据。若终端设备的第二总发射功率(即载波2压缩后的发射功率、载波4压缩后的发射功率，与，载波1、载波3的发射功率之和)仍然大于最大允许发射功率，则终端设备可以再从剩余的载波(即载波1和载波3)中再确定一个发射功率最大的载波作为第二载波，以此循环，直至终端设备的第二总发射功率小于或等于最大允许发射功率。If the transmit power of the first channel of the carrier 4 is compressed, the second total transmit power of the terminal device (ie, the transmit power after the carrier 2 is compressed, the transmit power after the carrier 4 is compressed, and the transmit power of the carrier 1 and the carrier 3) The sum is less than or equal to the maximum allowed transmit power, and the terminal device can use the 4 carriers to transmit data through the second total transmit power of the terminal device. If the second total transmit power of the terminal device (ie, the transmit power after the carrier 2 is compressed, the transmit power after the carrier 4 is compressed, and the sum of the transmit power of the carrier 1 and the carrier 3) is still greater than the maximum allowable transmit power, the terminal device A carrier with the highest transmission power may be further determined from the remaining carriers (ie, carrier 1 and carrier 3) as the second carrier, and cycled until the second total transmit power of the terminal device is less than or equal to the maximum allowed transmit power.

本发明实施例提供的发射功率压缩方法，在终端设备对第一载波的第一信道的发射功率进行压缩之后，若终端设备的第二总发射功率仍然大于最大允许发射功率，终端设备可以进一步地的从未执行功率压缩的载波中确定第二载波，对第二载波的发射功率进行压缩，并以此循环，直至终端设备的第二总发射功率小于或等于最大允许发射功率，从而使得终端设备可以使用该多个载波发送数据。通过这种按照发射功率从高到低的顺序来选择第一载波执行发射功率压缩，使得终端设备在压缩每个第一载波的发射功率时，均可以大幅度的压缩该第一载波的发射功率，进而可以大幅度的压缩终端设备的第一总发射功率，以使得终端设备在压缩完该第一载波的第一信道的发射功率之后，终端设备的总发射功率小于或等于终端设备的最大允许发射功率的概率较高，提高了发射功率的压缩效果，也提高了终端设备发送数据的效率。A method for compressing a transmit power provided by an embodiment of the present invention, where the terminal device is first to the first carrier After the transmission power of the channel is compressed, if the second total transmit power of the terminal device is still greater than the maximum allowable transmit power, the terminal device may further determine the second carrier and the transmit power for the second carrier from the carrier that does not perform power compression. Compression is performed and cycled until the second total transmit power of the terminal device is less than or equal to the maximum allowed transmit power, thereby enabling the terminal device to transmit data using the plurality of carriers. Selecting the first carrier according to the order of the transmit power from high to low performs transmit power compression, so that the terminal device can greatly compress the transmit power of the first carrier when compressing the transmit power of each first carrier. Therefore, the first total transmit power of the terminal device can be greatly compressed, so that after the terminal device compresses the transmit power of the first channel of the first carrier, the total transmit power of the terminal device is less than or equal to the maximum allowable of the terminal device. The probability of transmitting power is high, the compression effect of the transmission power is improved, and the efficiency of transmitting data by the terminal device is also improved.

进一步地，本实施例四涉及的是在上述终端设备对所有载波的第一信道的发射功率均进行压缩之后，若终端设备的总发射功率(即所有载波压缩后的发射功率之和)仍大于最大允许发射功率，终端设备从多个载波中确定第一载波，并对该第一载波的第二信道执行非连续发送(Discontinuous Transmission，简称：DTX)的具体过程。则在上述实施例的基础上，上述方法还可以包括：终端设备可以从多个载波中确定第一载波，并对该第一载波的第二信道执行非连续发送(Discontinuous Transmission，简称：DTX)。Further, in the fourth embodiment, after the terminal device compresses the transmit power of the first channel of all carriers, if the total transmit power of the terminal device (that is, the sum of the transmit powers after all carriers are compressed) is still greater than The maximum allowable transmit power, the terminal device determines the first carrier from the plurality of carriers, and performs a specific process of discontinuous transmission (DTX) for the second channel of the first carrier. On the basis of the foregoing embodiment, the method may further include: the terminal device may determine the first carrier from the multiple carriers, and perform discontinuous transmission (DTX) on the second channel of the first carrier. .

具体的，现有技术中，若终端设备对所有载波的第一信道的发射功率均进行压缩之后，终端设备的总发射功率(即所有载波压缩后的发射功率之和)仍大于最大允许发射功率，则终端设备会对所有载波上的所有信道进行等比压缩，即在保持每个载波的其他信道与该载波的DPCCH之间的功率比不变的基础上，通过压缩所有载波的DPCCH的发射功率，使得每个载波上的其他信道的发射功率相应地被等比压缩。虽然采用这种方式，可以大幅度的降低终端设备的总发射功率，使终端设备的总发射功率小于或等于最大允许发射功率，但是，若某一载波配置有传输语音业务的信道(例如：DPDCH)，则上述终端设备在对所有载波执行上述等比压缩的过程中，也会相应的等比压缩配置有传输终端设备的语音业务的信道(例如：DPDCH)的载波的发射功率，从而等比压缩配置有传输终端设备的语音业务的信道的发射功率，使得传输终端设备的语音业务的信道在使用压缩后的发射功率进行语音业务传输时，传输失败的概率较高，甚至造成掉话。 Specifically, in the prior art, if the terminal device compresses the transmit power of the first channel of all carriers, the total transmit power of the terminal device (that is, the sum of the transmit powers after all carriers are compressed) is still greater than the maximum allowable transmit power. Then, the terminal device performs equal-compression compression on all channels on all carriers, that is, by transmitting the DPCCH of all carriers by maintaining the power ratio between the other channels of each carrier and the DPCCH of the carrier unchanged. The power is such that the transmit power of the other channels on each carrier is correspondingly compressed in proportion. In this way, the total transmit power of the terminal device can be greatly reduced, so that the total transmit power of the terminal device is less than or equal to the maximum allowable transmit power, but if a certain carrier is configured with a channel for transmitting voice services (for example: DPDCH) The above-mentioned terminal device performs the above-described proportional compression on all the carriers, and correspondingly compresses the transmission power of the carrier of the channel (for example, DPDCH) of the voice service of the transmission terminal device, and thus the ratio The transmission power of the channel for transmitting the voice service of the terminal device is compressed, so that when the channel of the voice service of the transmission terminal device uses the compressed transmission power for voice service transmission, the probability of transmission failure is high, and even dropped calls are caused.

而在本实施例中，若上述终端设备对所有载波的第一信道的发射功率均进行压缩之后，终端设备的总发射功率仍大于最大允许发射功率，终端设备可以先不执行等比压缩，而是从多个载波中确定第一载波之后，对第一载波上的优先级较低的第二信道执行DTX，以降低第一载波的总发射功率，进而降低终端设备的总发射功率。此时，若终端设备的某一载波配置有传输终端设备的语音业务的信道(例如：DPDCH)，则通过这种方式，可以在降低终端设备的总发射功率的基础上，保证了传输语音业务的信道的功率不被压缩，可以使用终端设备本身设置分配的发射功率发送数据，使终端设备可以正常传输语音业务。In this embodiment, after the terminal device compresses the transmit power of the first channel of all carriers, the total transmit power of the terminal device is still greater than the maximum allowable transmit power, and the terminal device may not perform equal-compression first. After determining the first carrier from the multiple carriers, DTX is performed on the second channel with a lower priority on the first carrier to reduce the total transmit power of the first carrier, thereby reducing the total transmit power of the terminal device. In this case, if a certain carrier of the terminal device is configured with a channel for transmitting the voice service of the terminal device (for example, DPDCH), in this manner, the voice transmission service can be guaranteed on the basis of reducing the total transmission power of the terminal device. The power of the channel is not compressed, and the terminal device itself can be used to set the transmitted transmit power to transmit data, so that the terminal device can normally transmit the voice service.

具体实现时，上述终端设备可以使用实施例二所示的方式，从多个载波中确定第一载波，从而对该第一载波的信道执行DTX，即终端设备在此次发送周期不发送第一载波的第二信道，以降低终端设备的总发射功率，使终端设备的总发射功率可以小于或等于最大允许发射功率。其中，上述第二信道例如可以包括：E-DPDCH、E-DPCCH、HS-DPCCH的信道质量指示(Channel Quality Indicator，简称：CQI)域等中的一个或多个。可选的，可以对第一载波的E-DPDCH、E-DPCCH、HS-DPCCH的CQI域同时执行DTX，还可以先对第一载波的E-DPDCH执行DTX，若对该第一载波的所有E-DPDCH执行完DTX之后，终端设备的总发射功率仍然大于最大允许发射功率，则可以进一步对该第一载波的E-DPCCH执行DTX。若对该第一载波的E-DPCCH执行完DTX之后，终端设备的总发射功率仍然大于最大允许发射功率，则可以进一步地对该第一载波的HS-DPCCH的CQI域部分执行DTX等，本发明对此不进行限定。进一步地，若上述终端设备在对第一载波的所有第二信道执行完DTX之后，终端设备当前的总发射功率仍然大于最大允许发射功率，则终端设备可以在从未执行DTX的载波中确定第二载波，并对该第二载波的第二信道执行DTX，以此循环，直至终端设备的总发射功率小于或等于最大允许发射功率。In a specific implementation, the terminal device may determine the first carrier from the multiple carriers by using the method shown in the second embodiment, so that DTX is performed on the channel of the first carrier, that is, the terminal device does not send the first in the sending period. The second channel of the carrier is used to reduce the total transmit power of the terminal device, so that the total transmit power of the terminal device can be less than or equal to the maximum allowable transmit power. The second channel may include, for example, one or more of a Channel Quality Indicator (CQI) field of the E-DPDCH, the E-DPCCH, and the HS-DPCCH. Optionally, DTX may be performed on the CQI domain of the E-DPDCH, E-DPCCH, and HS-DPCCH of the first carrier, and DTX may be performed on the E-DPDCH of the first carrier, if all of the first carrier is used. After the E-DPDCH performs DTX, the total transmit power of the terminal device is still greater than the maximum allowed transmit power, and DTX may be further performed on the E-DPCCH of the first carrier. If the total transmit power of the terminal device is still greater than the maximum allowable transmit power after the DTX is performed on the E-DPCCH of the first carrier, the DQ of the CQI domain portion of the HS-DPCCH of the first carrier may be further performed. The invention does not limit this. Further, if the terminal device performs the DTX on all the second channels of the first carrier, and the current total transmit power of the terminal device is still greater than the maximum allowed transmit power, the terminal device may determine the first carrier in the DTX. The two carriers perform DTX on the second channel of the second carrier, and the loop is performed until the total transmit power of the terminal device is less than or equal to the maximum allowed transmit power.

可选的，在本发明的另一实现方式中，上述终端设备还可以采用现有技术的方式，从多个载波中确定一个DPCCH功率最大的载波，从而对该载波的第二信道执行DTX。若终端设备在对该载波的所有第二信道执行完DTX之后，终端设备当前的总发射功率仍然大于最大允许发射功率，则终端设备可以在从未执行DTX的载波中确定新的DPCCH功率最大的载波，并对该新的DPCCH功率最大的载波的第二信道执行DTX，以此循环，直至终端设备的总发射功率小于或等于最大允许发射功率。其中，上述终端设备对确定的DPCCH功率最大的载波的一个第二信道执行DTX，还是对该载波的所有第二信道执行DTX，具体可以参见上述对第一载波执行DTX的描述，本发明对此不再赘述。Optionally, in another implementation manner of the present invention, the foregoing terminal device may further determine, by using a prior art manner, a carrier with the highest DPCCH power from the plurality of carriers, thereby performing DTX on the second channel of the carrier. If the terminal device performs the DTX on all the second channels of the carrier, and the current total transmit power of the terminal device is still greater than the maximum allowed transmit power, the terminal device The new carrier with the highest DPCCH power can be determined in the carrier that does not perform DTX, and DTX is performed on the second channel of the carrier with the largest DPCCH power, and the loop is performed until the total transmit power of the terminal device is less than or equal to the maximum. Allow transmission power. The foregoing terminal device performs DTX on a second channel of the carrier with the highest DPCCH power, or performs DTX on all the second channels of the carrier. For details, refer to the description of performing DTX on the first carrier. No longer.

可选的，在本发明的另一实现方式中，上述终端设备还可以对所有的载波的第二信道同时执行DTX。具体实现时，终端设备可以对所有载波的E-DPDCH、E-DPCCH、HS-DPCCH的CQI域同时执行DTX，还可以先对所有载波的E-DPDCH执行DTX，若对所有载波的所有E-DPDCH执行完DTX之后，终端设备的总发射功率仍然大于最大允许发射功率，则可以进一步对所有载波的E-DPCCH执行DTX。若对所有载波的E-DPCCH执行完DTX之后，终端设备的总发射功率仍然大于最大允许发射功率，则可以进一步地对所有载波的HS-DPCCH的CQI域部分执行DTX等，以达到终端设备的总发射功率小于或等于最大允许发射功率的目的。Optionally, in another implementation manner of the present invention, the foregoing terminal device may also perform DTX on the second channel of all carriers simultaneously. In a specific implementation, the terminal device may perform DTX on the E-DPDCH, the E-DPCCH, and the CQI field of the HS-DPCCH of all carriers simultaneously, and may perform DTX on the E-DPDCH of all carriers first, if all E-s of all carriers After the DPDCH performs DTX, the total transmit power of the terminal device is still greater than the maximum allowed transmit power, and DTX can be further performed on the E-DPCCH of all carriers. If the total transmit power of the terminal device is still greater than the maximum allowable transmit power after the DTX is performed on the E-DPCCH of all carriers, DTX and the like may be further performed on the CQI domain portion of the HS-DPCCH of all carriers to reach the terminal device. The total transmit power is less than or equal to the maximum allowable transmit power.

本发明实施例提供的发射功率压缩方法，在终端设备对所有载波的第一信道的发射功率进行压缩之后，若终端设备的总发射功率仍然大于最大允许发射功率，终端设备可以进一步地的从多个载波中确定第一载波，并对第一载波上传输优先级较低的第二信道执行DTX，来降低第一载波的总发射功率，进而降低终端设备的总发射功率。通过这种方式，可以在终端设备配置了语音业务的信道时，可以在降低终端设备的总发射功率的基础上，保证终端设备可以正常传输语音业务。The method for compressing the transmit power provided by the embodiment of the present invention, after the terminal device compresses the transmit power of the first channel of all carriers, if the total transmit power of the terminal device is still greater than the maximum allowable transmit power, the terminal device may further The first carrier is determined in the carrier, and DTX is performed on the second channel with the lower priority of the first carrier to reduce the total transmit power of the first carrier, thereby reducing the total transmit power of the terminal device. In this way, when the terminal device configures the channel of the voice service, the terminal device can normally transmit the voice service on the basis of reducing the total transmit power of the terminal device.

进一步地，在上述实施例的基础上，本实施例五涉及的是终端设备如何确定压缩第一载波的第一信道的增益因子的功率压缩因子的具体过程。在本实施例中，上述S102可以分为三种情况：Further, based on the foregoing embodiment, the fifth embodiment relates to a specific process of how the terminal device determines the power compression factor of the gain factor of the first channel of the first carrier.

具体的，如上述实施例所说，上述终端设备可以使用多个载波发送数据，其中，每个载波上包括至少一个第一信道，该第一信道的TTI长度可以相同，也可以不同，例如：上述每个载波的第一信道的TTI长度可以为10ms，还可以为2ms。当第一信道的TTI长度越长时，第一信道在一个TTI内所使用的总发射功率越大，当第一信道的TTI长度越小时，第一信道在一个TTI内所使用的总发射功率越小。现有技术中，终端设备在对其使用的多个载波中的某一载波的第一信道进行发射功率压缩时，均采用同一功率压缩因子对其进行压缩，此时，若该载波的第一信道使用的是较短的TTI长度，则终端设备在使用该功率压缩因子对其发射功率进行压缩后，本身发射功率较小的第一信道易因压缩后的发射功率过小，导致发送数据失败的概率较高。Specifically, as described in the foregoing embodiment, the terminal device may send data by using multiple carriers, where each carrier includes at least one first channel, and the TTI lengths of the first channel may be the same or different, for example: The TTI length of the first channel of each carrier may be 10 ms, and may also be 2 ms. When the TTI length of the first channel is longer, the total transmit power used by the first channel in one TTI is larger, and the smaller the TTI length of the first channel is, the total transmit power used by the first channel in one TTI. The smaller. In the prior art, when the terminal device performs transmission power compression on the first channel of a certain one of the multiple carriers used by the terminal device, the same power compression factor is used to compress the terminal device, and at this time, if the carrier is the first The channel uses a shorter TTI length. After the terminal device compresses the transmit power using the power compression factor, the first channel with a small transmit power is too small because the compressed transmit power is too small, causing the data to fail. The probability is higher.

而在本实施例中，当上述每个载波的第一信道的TTI长度不同时，上述终端设备在从多个载波中确定出第一载波之后，可以根据第一载波的第一信道的TTI长度，先确定适配于第一载波的第一信道的功率压缩因子，以使得第一信道的TTI长度较长时，终端设备可以使用一个较大的功率压缩因子对其进行压缩，第一信道的TTI长度较短时，终端设备可以使用一个较小的功率压缩因子对其进行压缩。通过这种方式，可以避免第一信道在使用较短的TTI长度时，终端设备仍然采用较大的功率压缩因子对其进行压缩，导致第一信道在使用压缩后的发射功率发送数据失败的概率较大的问题，提高了第一信道传输数据的效率。In this embodiment, when the TTI length of the first channel of each carrier is different, the terminal device may determine the TTI length of the first channel of the first carrier after determining the first carrier from the multiple carriers. First, determining a power compression factor of the first channel adapted to the first carrier, so that when the TTI length of the first channel is long, the terminal device can compress the first channel by using a larger power compression factor. When the TTI length is short, the terminal device can compress it with a smaller power compression factor. In this way, it can be avoided that when the first channel uses a shorter TTI length, the terminal device still compresses it with a larger power compression factor, resulting in a probability that the first channel fails to transmit data after using the compressed transmit power. A larger problem improves the efficiency of data transmission on the first channel.

其中，本发明实施例不限定上述终端设备如何根据第一载波的第一信道的TTI长度，确定第一载波的第一信道的功率压缩因子的具体实现方式。可选的，上述终端设备可以根据Power_scaling_factor＝A·TTI_length，来确定第一载波的第一信道的功率压缩因子Power_scaling_factor；其中，上述TTI_length表示第一载波的第一信道的TTI长度，上述A为预设的压缩系数。可选的，上述终端设备还可以根据

Optionally, the terminal device may determine, according to Power_scaling_factor=A·TTI_length, a power compression factor Power_scaling_factor of the first channel of the first carrier, where the TTI_length represents a TTI length of the first channel of the first carrier, where the A is a pre- Set the compression factor. Optionally, the foregoing terminal device may also be based on

The power compression factor Power_scaling_factor or the like of the first channel of the first carrier is determined.

S302、终端设备根据第一载波的第一信道的功率压缩因子，对第一载波的第一信道的增益因子进行压缩。S302. The terminal device compresses a gain factor of the first channel of the first carrier according to a power compression factor of the first channel of the first carrier.

When it is compressed, when the TTI length of the first channel is short, the terminal device can compress it with a smaller power compression factor. In this way, it can be avoided that when the first channel uses a shorter TTI length, the terminal device still compresses it with a larger power compression factor, resulting in a probability that the first channel fails to transmit data after using the compressed transmit power. A larger problem improves the efficiency of data transmission on the first channel.

FIG. 4 is a schematic flowchart of Embodiment 7 of the method for compressing the transmit power according to the embodiment of the present invention. As shown in FIG. 4, the above S102 may include:

S401、终端设备根据第一载波所在的频点，确定第一载波的第一信道的功率压缩因子。S401. The terminal device determines a power compression factor of the first channel of the first carrier according to the frequency point where the first carrier is located.

具体的，如上述实施例所说，上述终端设备可以使用多个载波发送数据，其中，每个载波所在的频点可以相同，也可以不同。当载波所在的频点较高时，终端设备在该载波占用的发射功率较大，该载波的第一信道的发射功率也较大，当载波所在的频点较低时，终端设备在该载波占用的发射功率较低，该载波的第一信道的发射功率也较小。然而，现有技术中，终端设备在对其多个载波的某一载波的第一信道进行发射功率压缩时，均采用同一功率压缩因子对其进行压缩，此时，若该第一信道工作在较低的频点，则终端设备在使用该功率压缩因子对其发射功率进行压缩后，本身发射功率较小的第一信道易因压缩后的发射功率过小，导致发送数据失败的概率较高。Specifically, as described in the foregoing embodiment, the terminal device may send data by using multiple carriers, where the frequency points of each carrier may be the same or different. When the frequency of the carrier is high, the transmission power of the terminal device on the carrier is large, and the transmission power of the first channel of the carrier is also large. When the frequency of the carrier is low, the terminal device is in the carrier. The occupied transmit power is low, and the transmit power of the first channel of the carrier is also small. However, in the prior art, when the terminal device performs transmission power compression on the first channel of a certain carrier of the plurality of carriers, the terminal device compresses the same using the same power compression factor. At this time, if the first channel works in At a lower frequency point, after the terminal device compresses the transmit power by using the power compression factor, the first channel with a small transmit power is too small because the compressed transmit power is too small, resulting in a high probability of failure of transmitting data. .

而在本实施例中，当上述每个载波所在的频点不同时，上述终端设备在从多个载波中确定出第一载波之后，可以根据第一载波所在的频点，先确定适配于第一载波的第一信道的功率压缩因子，以使得第一信道工作在高频点时，终端设备可以使用一个较大的功率压缩因子对其进行压缩，第一信道工作在低频点时，终端设备可以使用一个较小的功率压缩因子对其进行压缩。通过这种方式，可以避免第一信道工作在低频点时，终端设备仍然采用较大的功率压缩因子对其进行压缩，导致第一信道压缩后的发射功率过小使得发送数据失败的概率较大的问题，提高了第一信道传输数据的效率。In this embodiment, when the frequency of each of the carriers is different, after determining the first carrier from the multiple carriers, the terminal device may first determine that the frequency is determined according to the frequency of the first carrier.

When the first channel operates at a low frequency point, the terminal The device can compress it with a smaller power compression factor. In this way, it can be avoided that the terminal device still adopts a larger when the first channel operates at a low frequency point. The power compression factor compresses it, causing the transmission power of the first channel to be compressed to be too small, so that the probability of failure of transmitting data is large, and the efficiency of transmitting data on the first channel is improved.

其中，本发明实施例不限定上述终端设备如何根据第一载波所在的频点，确定第一载波的第一信道的功率压缩因子的具体实现方式。可选的，上述终端设备可以根据

来确定第一载波的第一信道的功率压缩因子Power_scaling_factor；其中，上述F表示第一载波所在的频点，上述B为预设的压缩系数。可选的，上述终端设备还可以根据Power_scaling_factor＝F×B，来确定第一载波的第一信道的功率压缩因子Power_scaling_factor等。The embodiment of the present invention does not limit how the terminal device determines the specific implementation manner of the power compression factor of the first channel of the first carrier according to the frequency point where the first carrier is located. Optionally, the foregoing terminal device may be based on

Determining a power compression factor Power_scaling_factor of the first channel of the first carrier; wherein F represents a frequency point at which the first carrier is located, and B is a preset compression coefficient. Optionally, the terminal device may further determine a power compression factor Power_scaling_factor of the first channel of the first carrier according to Power_scaling_factor=F×B.

S402、终端设备根据第一载波的第一信道的功率压缩因子，对第一载波的第一信道的增益因子进行压缩。S402. The terminal device compresses a gain factor of the first channel of the first carrier according to a power compression factor of the first channel of the first carrier.

其中，本步骤的具体描述可以参见上述实施例一的S102的描述，本实施例对此不再赘述。For a detailed description of this step, refer to the description of S102 in the foregoing Embodiment 1, and this embodiment will not be described again.

本发明实施例提供的发射功率压缩方法，终端设备在从多个载波中确定出一个发射功率最大的第一载波之后，可以根据第一载波所在的频点，确定第一载波的第一信道的功率压缩因子，进而根据该功率压缩因子对第一载波的第一信道的增益因子进行压缩，以使得第一信道所在的频点较高时，终端设备可以使用一个较大的功率压缩因子对其进行压缩，第一信道所在的频点较低时，终端设备可以使用一个较小的功率压缩因子对其进行压缩。通过这种方式，可以避免第一信道工作在较低的频点时，终端设备仍然采用较大的功率压缩因子对其进行压缩，导致第一信道在使用压缩后的发射功率发送数据失败的概率较大的问题，提高了第一信道传输数据的效率。The method for compressing a transmit power provided by the embodiment of the present invention, after determining a first carrier with the largest transmit power from the plurality of carriers, the terminal device may determine the first channel of the first carrier according to the frequency point where the first carrier is located. a power compression factor, and then compressing a gain factor of the first channel of the first carrier according to the power compression factor, so that when the frequency of the first channel is higher, the terminal device can use a larger power compression factor to When compression is performed, when the frequency at which the first channel is located is low, the terminal device can compress it using a smaller power compression factor. In this way, it is possible to prevent the terminal device from still compressing with a larger power compression factor when the first channel operates at a lower frequency point, thereby causing the probability that the first channel fails to transmit data after using the compressed transmit power. A larger problem improves the efficiency of data transmission on the first channel.

第三种情况：终端设备根据第一载波所占用的发射功率，确定第一载波的第一信道的功率压缩因子，图5为本发明实施例提供的发射功率压缩方法实施例八的流程示意图。如图5所示，上述S102可以包括：In the third case, the terminal device determines the power compression factor of the first channel of the first carrier according to the transmit power occupied by the first carrier. FIG. 5 is a schematic flowchart of the eighth embodiment of the method for compressing the transmit power according to the embodiment of the present invention. As shown in FIG. 5, the above S102 may include:

S501、终端设备根据第一载波所占用的发射功率，确定第一载波的第一信道的功率压缩因子。S501. The terminal device determines a power compression factor of the first channel of the first carrier according to the transmit power occupied by the first carrier.

具体的，如上述实施例所说，上述终端设备可以使用多个载波发送数据，其中，终端设备在每个载波占用的发射功率可以相同，也可以不同。若终端设备在某一载波占用的发射功率较大，则该载波的第一信道的发射功率也较大，若终端设备在某一载波占用的发射功率较小，则该载波的第一信道的发射功率也较小。然而，现有技术中，终端设备在对其多个载波的某一载波的第一信道进行发射功率压缩时，均采用同一功率压缩因子对其进行压缩，此时，若该第一信道的发射功率较小，则终端设备在使用该功率压缩因子对其发射功率进行压缩后，本身发射功率较小的第一信道易因压缩后的发射功率过小，导致发送数据失败的概率较高。Specifically, as described in the foregoing embodiment, the terminal device may send data by using multiple carriers, where the transmission power occupied by the terminal device on each carrier may be the same or different. If the transmission power of the terminal equipment occupied by a certain carrier is large, the transmission power of the first channel of the carrier is also large. If the transmission power of the terminal equipment occupied by a certain carrier is small, the first channel of the carrier is used. The transmission power is also small. However, in the prior art, when the terminal device performs transmission power compression on the first channel of a certain carrier of multiple carriers, it uses the same power compression factor to compress it. At this time, if the first channel is transmitted, If the power is small, the terminal device compresses the transmit power by using the power compression factor, and the first channel with a small transmit power is too small because the compressed transmit power is too small, resulting in a high probability of failure of transmitting data.

而在本实施例中，当上述每个载波第一载波所占用的发射功率不同时，上述终端设备在从多个载波中确定出第一载波之后，可以根据第一载波所占用的发射功率，先确定适配于第一载波的第一信道的功率压缩因子，以使得第一信道发射功率较大时，终端设备可以使用一个较大的功率压缩因子对其进行压缩，第一信道发射功率较小时，终端设备可以使用一个较小的功率压缩因子对其进行压缩。通过这种方式，可以避免第一信道发射功率较小时，终端设备仍然采用较大的功率压缩因子对其进行压缩，导致第一信道在使用压缩后的发射功率发送数据失败的概率较大的问题，提高了第一信道传输数据的效率。In this embodiment, when the transmit power occupied by the first carrier of each carrier is different, the terminal device may determine the transmit power occupied by the first carrier after determining the first carrier from the multiple carriers. First determining a power compression factor of the first channel adapted to the first carrier, so that when the first channel transmission power is large, the terminal device can compress the first channel by using a larger power compression factor. In hours, the terminal device can compress it with a smaller power compression factor. In this way, when the transmit power of the first channel is small, the terminal device still compresses the data with a large power compression factor, which causes the probability that the first channel fails to transmit data after using the compressed transmit power. , improving the efficiency of transmitting data on the first channel.

其中，本发明实施例不限定上述终端设备如何根据第一载波所占用的发射功率，确定第一载波的第一信道的功率压缩因子的具体实现方式。例如：上述终端设备可以根据

来确定第一载波的第一信道的功率压缩因子Power_scaling_factor；其中，上述P_载波表示第一载波所占用的发射功率，上述P_总为第一总发射功率，上述C为预设的压缩系数。The embodiment of the present invention does not limit how the terminal device determines the specific implementation manner of the power compression factor of the first channel of the first carrier according to the transmit power occupied by the first carrier. For example: the above terminal device can be based on

The power compression factor Power_scaling_factor of the first channel of the first carrier is determined; wherein the P _carrier represents the transmit power occupied by the first carrier, the P is _always the first total transmit power, and the C is a preset compression coefficient.

S502、终端设备根据第一载波的第一信道的功率压缩因子，对第一载波的第一信道的增益因子进行压缩。S502. The terminal device compresses a gain factor of the first channel of the first carrier according to a power compression factor of the first channel of the first carrier.

本发明实施例提供的发射功率压缩方法，终端设备在从多个载波中确定出一个发射功率最大的第一载波之后，可以根据第一载波所占用的发射功率，确定第一载波的第一信道的功率压缩因子，进而根据该功率压缩因子对第一载波的第一信道的增益因子进行压缩，以使得第一信道占用的发射功率较大时，终端设备可以使用一个较大的功率压缩因子对其进行压缩，第一信道占用的发射功率较小时，终端设备可以使用一个较小的功率压缩因子对其进行压缩。通过这种方式，可以避免第一信道占用的发射功率较小时，终端设备仍然采用较大的功率压缩因子对其进行压缩，导致第一信道在使用压缩后的发射功率发送数据失败的概率较大的问题，提高了第一信道传输数据的效率。The method for compressing the transmit power provided by the embodiment of the present invention, after determining the first carrier with the largest transmit power from the multiple carriers, the terminal device may determine the first channel of the first carrier according to the transmit power occupied by the first carrier. a power compression factor, and then compressing a gain factor of the first channel of the first carrier according to the power compression factor, so that when the transmit power occupied by the first channel is large, the terminal device can use a larger power compression factor pair. When it is compressed, when the transmit power occupied by the first channel is small, the terminal device can compress it with a smaller power compression factor. In this way, it is possible to avoid that when the transmission power occupied by the first channel is small, the terminal The device still compresses the data with a large power compression factor, which causes the first channel to have a high probability of transmitting data using the compressed transmit power, and improves the efficiency of transmitting data on the first channel.

图6为本发明实施例提供的发射功率压缩方法实施例九的流程示意图。在本实施例中，上述终端可以使用多个载波发送数据，本实施例九涉及的是终端设备通过分别使用每个载波的第一信道的功率压缩因子，同时压缩所有载波的发射功率，以降低终端设备的总发射功率的具体过程。如图6所示，该方法可以包括：FIG. 6 is a schematic flowchart diagram of Embodiment 9 of a method for compressing a transmit power according to an embodiment of the present invention. In this embodiment, the terminal may use multiple carriers to transmit data, and the ninth embodiment relates to the terminal device compressing the transmit power of all carriers by using the power compression factor of the first channel of each carrier, respectively, to reduce The specific process of the total transmit power of the terminal equipment. As shown in FIG. 6, the method may include:

S601、若终端设备的第一总发射功率大于终端设备的最大允许发射功率，则终端设备根据每个载波的载波信息，确定每个载波的第一信道的功率压缩因子；第一总发射功率为终端设备为各载波设置的发射功率之和；载波信息包括：载波的第一信道的TTI长度、载波所在的频点、载波所占用的发射功率。S601. If the first total transmit power of the terminal device is greater than the maximum allowed transmit power of the terminal device, the terminal device determines, according to the carrier information of each carrier, a power compression factor of the first channel of each carrier; the first total transmit power is The sum of the transmit powers set by the terminal device for each carrier; the carrier information includes: a TTI length of the first channel of the carrier, a frequency point where the carrier is located, and a transmit power occupied by the carrier.

具体的，在本实施例中，上述终端设备可以使用多个载波发送上行数据，该多个载波可以为工作在相同频点的载波，也可以为工作在不同频点的载波。其中，上述终端设备所使用的多个载波中的每个载波均配置有至少一个用于传输终端设备的数据业务的第一信道，该第一信道例如可以为上述所说的E-DPDCH等。上述第一信道的TTI长度可以相同，也可以不同，例如：上述每个载波的第一信道的TTI长度可以为10ms，还可以为2ms。Specifically, in this embodiment, the terminal device may send uplink data by using multiple carriers, where the multiple carriers may be carriers operating at the same frequency point, or may be carriers operating at different frequency points. Each of the plurality of carriers used by the terminal device is configured with at least one first channel for transmitting data services of the terminal device, and the first channel may be, for example, the E-DPDCH or the like mentioned above. The length of the TTI of the first channel may be the same or different. For example, the length of the TTI of the first channel of each carrier may be 10 ms or 2 ms.

上述终端设备在使用该多个载波发送上行数据时，每个载波的每个信道会使用相同或者不同的发射功率。具体地，终端设备会为每个载波的DPCCH设置一定的发射功率，为该载波的其他每个信道设置一个增益因子，该载波上的其他信道与该载波的DPCCH的功率之比等于该信道的增益因子与DPCCH的增益因子比值的平方，其中，DPCCH对应的增益因子可以为1。每个载波的所有信道的发射功率之和为每个载波的发射功率，所有载波的发射功率之和即为终端设备的第一总发射功率。在本实施例中，若该第一总发射功率大于终端设备的最大允许发射功率，则终端设备可以根据每个载波的载波信息，为每个载波的第一信道确定适配于该第一信道的功率压缩因子，以使得终端设备在使用该功率压缩因子，对该第一信道进行功率压缩时，不会出现将发射功率压缩过多，导致第一信道使用压缩后的发射功率发送数据失败的情况。When the terminal device uses the multiple carriers to transmit uplink data, each channel of each carrier uses the same or different transmission power. Specifically, the terminal device sets a certain transmit power for the DPCCH of each carrier, and sets a gain factor for each of the other channels of the carrier, and the ratio of the power of the other channel on the carrier to the power of the DPCCH of the carrier is equal to the channel. The gain factor is the square of the gain factor ratio of the DPCCH, where the gain factor corresponding to the DPCCH can be one. The sum of the transmit powers of all the channels of each carrier is the transmit power of each carrier, and the sum of the transmit powers of all the carriers is the first total transmit power of the terminal device. In this embodiment, if the first total transmit power is greater than the maximum allowed transmit power of the terminal device, the terminal device may determine, according to the carrier information of each carrier, the first channel adapted to the first channel. The power compression factor is such that when the terminal device uses the power compression factor to perform power compression on the first channel, the transmission power is not compressed too much, and the first channel uses the compressed transmit power. The case where the data is sent fails.

S602、终端设备根据每个载波的第一信道的功率压缩因子，对每个载波的第一信道的增益因子进行压缩。S602. The terminal device compresses a gain factor of the first channel of each carrier according to a power compression factor of the first channel of each carrier.

具体的，上述终端设备在根据每个载波的载波信息，为每个载波的第一信道确定一个功率压缩因子之后，就可以使用每个载波的第一信道的功率压缩因子，对每个载波的第一信道的发射功率所对应的增益因子进行压缩。由于每个载波的第一信道的发射功率与DPCCH的发射功率的比值是两者增益因子的平方，因此，通过压缩该载波的第一信道的增益因子，达到了压缩该载波的第一信道的发射功率的目的，进而通过压缩每个载波的第一信道的发射功率，达到了压缩终端设备的第一总发射功率的目的。其中，上述终端设备如何使用每个载波的第一信道的功率压缩因子，对每个载波的第一信道的发射功率所对应的增益因子进行压缩具体可以参见现有技术，本发明对此不再赘述。Specifically, after the terminal device determines a power compression factor for the first channel of each carrier according to carrier information of each carrier, the power compression factor of the first channel of each carrier may be used, for each carrier. The gain factor corresponding to the transmit power of the first channel is compressed. Since the ratio of the transmit power of the first channel of each carrier to the transmit power of the DPCCH is the square of the gain factor of the two, the first channel of the carrier is compressed by compressing the gain factor of the first channel of the carrier. The purpose of transmitting power, and thereby compressing the transmit power of the first channel of each carrier, achieves the purpose of compressing the first total transmit power of the terminal device. For example, how to use the power compression factor of the first channel of each carrier to compress the gain factor corresponding to the transmit power of the first channel of each carrier can be referred to the prior art, and the present invention no longer Narration.

本发明实施例提供的发射功率压缩方法，在终端设备的第一总发射功率大于终端设备的最大允许发射功率时，终端设备可以根据每个载波的载波信息，确定适配于每个载波的第一信道的功率压缩因子，进而可以使用每个载波的第一信道的功率压缩因子，对每个载波的第一信道的发射功率进行压缩，在达到压缩终端设备的第一总发射功率的目的的同时，使终端设备的每个载波的第一信道均可以使用压缩后的发射功率正常发送数据，提高了第一信道传输数据的效率。同时，通过对每个载波的第一信道的发射功率进行压缩的方式，可以大幅度的压缩第一载波的发射功率，进而可以大幅度的压缩终端设备的第一总发射功率，使终端设备压缩后的第一总发射功率小于或等于终端设备的最大允许发射功率的概率较高，提高了发射功率的压缩效果，也提高了终端设备发送数据的效率。In the transmit power compression method provided by the embodiment of the present invention, when the first total transmit power of the terminal device is greater than the maximum allowable transmit power of the terminal device, the terminal device may determine, according to the carrier information of each carrier, the first adapted to each carrier. a power compression factor of a channel, which in turn can compress the transmit power of the first channel of each carrier using the power compression factor of the first channel of each carrier, and achieve the purpose of compressing the first total transmit power of the terminal device At the same time, the first channel of each carrier of the terminal device can use the compressed transmit power to transmit data normally, which improves the efficiency of transmitting data on the first channel. At the same time, by compressing the transmit power of the first channel of each carrier, the transmit power of the first carrier can be greatly compressed, and the first total transmit power of the terminal device can be greatly compressed, so that the terminal device can be compressed. The probability that the first total transmit power is less than or equal to the maximum allowable transmit power of the terminal device is higher, the compression effect of the transmit power is improved, and the efficiency of transmitting data by the terminal device is also improved.

进一步地，在上述实施例的基础上，本实施例十涉及的是终端设备如何根据每个载波的载波信息，确定每个载波的第一信道的功率压缩因子的具体过程，则上述S601具体可以分为如下三种情况：Further, on the basis of the foregoing embodiment, the tenth embodiment relates to how the terminal device determines the power compression factor of the first channel of each carrier according to the carrier information of each carrier, and the foregoing S601 may specifically Divided into the following three cases:

第一种情况：上述载波信息为载波的第一信道的TTI长度，则上述S601具体可以包括：终端设备根据每个载波的第一信道的TTI长度，确定每个载波的第一信道的功率压缩因子。The first case: the carrier information is the TTI length of the first channel of the carrier, and the foregoing S601 may specifically include: determining, by the terminal device, the power compression of the first channel of each carrier according to the TTI length of the first channel of each carrier factor.

具体的，如上述实施例所说，上述终端设备可以使用多个载波发送数据，其中，每个载波上包括至少一个第一信道，该第一信道的TTI长度可以相同，也可以不同，例如：上述每个载波的第一信道的TTI长度可以为10ms，还可以为2ms。当第一信道的TTI长度越长时，第一信道在一个TTI内所使用的总发射功率越大，当第一信道的TTI长度越小时，第一信道在一个TTI内所使用的总发射功率越小。现有技术中，终端设备在对其使用的多个载波中的某一载波的第一信道进行发射功率压缩时，均采用同一功率压缩因子对其进行压缩，此时，若该载波的第一信道使用的是较短的TTI长度，则终端设备在使用该功率压缩因子对其发射功率进行压缩后，本身发射功率较小的第一信道易因压缩后的发射功率过小，导致发送数据失败的概率较高。Specifically, as described in the foregoing embodiment, the foregoing terminal device may use multiple carrier transmission numbers. According to the above, each carrier includes at least one first channel, and the TTI length of the first channel may be the same or different. For example, the TTI length of the first channel of each carrier may be 10 ms or 2 ms. . When the TTI length of the first channel is longer, the total transmit power used by the first channel in one TTI is larger, and the smaller the TTI length of the first channel is, the total transmit power used by the first channel in one TTI. The smaller. In the prior art, when the terminal device performs transmission power compression on the first channel of a certain one of the multiple carriers used by the terminal device, the same power compression factor is used to compress the terminal device, and at this time, if the carrier is the first The channel uses a shorter TTI length. After the terminal device compresses the transmit power using the power compression factor, the first channel with a small transmit power is too small because the compressed transmit power is too small, causing the data to fail. The probability is higher.

而在本实施例中，当上述每个载波的第一信道的TTI长度不同时，上述终端设备可以根据每个载波的第一信道的TTI长度，先确定适配于该载波的第一信道的功率压缩因子，以使得该载波的第一信道的TTI长度较长时，终端设备可以使用一个较大的功率压缩因子对其进行压缩，该载波的第一信道的TTI长度较短时，终端设备可以使用一个较小的功率压缩因子对其进行压缩。通过这种方式，可以避免某一载波的第一信道在使用较短的TTI长度时，终端设备仍然采用较大的功率压缩因子对其进行压缩，导致该载波的第一信道在使用压缩后的发射功率发送数据失败的概率较大的问题，提高了该载波的第一信道传输数据的效率。In this embodiment, when the TTI length of the first channel of each carrier is different, the terminal device may first determine the first channel that is adapted to the carrier according to the TTI length of the first channel of each carrier. The power compression factor is such that when the TTI length of the first channel of the carrier is long, the terminal device can compress it by using a larger power compression factor. When the TTI length of the first channel of the carrier is short, the terminal device It can be compressed using a smaller power compression factor. In this way, it can be avoided that when the first channel of a certain carrier uses a shorter TTI length, the terminal device still compresses it by using a larger power compression factor, so that the first channel of the carrier is compressed. The problem that the transmission power fails to transmit data is large, and the efficiency of transmitting data on the first channel of the carrier is improved.

其中，本发明实施例不限定上述终端设备如何根据每个载波的第一信道的TTI长度，确定每个载波的第一信道的功率压缩因子的具体实现方式。可选的，上述终端设备可以根据Power_scaling_factor＝A·TTI_length，来确定每个载波的第一信道的功率压缩因子Power_scaling_factor；其中，上述TTI_length表示该载波的第一信道的TTI长度，上述A为预设的压缩系数。可选的，上述终端设备还可以根据

来确定第一载波的第一信道的功率压缩因子Power_scaling_factor等。The embodiment of the present invention does not limit how the foregoing terminal device determines the specific implementation manner of the power compression factor of the first channel of each carrier according to the TTI length of the first channel of each carrier. Optionally, the terminal device may determine a power compression factor Power_scaling_factor of the first channel of each carrier according to Power_scaling_factor=A·TTI_length, where the TTI_length represents a TTI length of the first channel of the carrier, where the A is a preset Compression factor. Optionally, the foregoing terminal device may also be based on

第二种情况：上述载波信息为载波所在的频点，则上述S601具体可以包括：终端设备根据每个载波所在的频点，确定每个载波的第一信道的功率压缩因子。In the second case, the carrier information is the frequency of the carrier, and the foregoing S601 may include: determining, by the terminal device, a power compression factor of the first channel of each carrier according to a frequency point of each carrier.

具体的，如上述实施例所说，上述终端设备可以使用多个载波发送数据，其中，每个载波所在的频点可以相同，也可以不同。当载波所在的频点较高时，终端设备在该载波占用的发射功率较大，该载波的第一信道的发射功率也较大，当载波所在的频点较低时，终端设备在该载波占用的发射功率较低，该载波的第一信道的发射功率也较小。然而，现有技术中，终端设备在对其多个载波的某一载波的第一信道进行发射功率压缩时，均采用同一功率压缩因子对其进行压缩，此时，若该第一信道工作在较低的频点，则终端设备在使用该功率压缩因子对其发射功率进行压缩后，本身发射功率较小的第一信道易因压缩后的发射功率过小，导致发送数据失败的概率较高。Specifically, as described in the foregoing embodiment, the terminal device may send data by using multiple carriers, where the frequency points of each carrier may be the same or different. When the frequency at which the carrier is located is high, the transmission power occupied by the terminal device on the carrier is large, and the first channel of the carrier is transmitted. The power is also large. When the frequency at which the carrier is located is low, the transmission power occupied by the terminal device on the carrier is low, and the transmission power of the first channel of the carrier is also small. However, in the prior art, when the terminal device performs transmission power compression on the first channel of a certain carrier of the plurality of carriers, the terminal device compresses the same using the same power compression factor. At this time, if the first channel works in At a lower frequency point, after the terminal device compresses the transmit power by using the power compression factor, the first channel with a small transmit power is too small because the compressed transmit power is too small, resulting in a high probability of failure of transmitting data. .

而在本实施例中，当上述每个载波所在的频点不同时，上述终端设备可以根据每个载波所在的频点，先确定适配于每个载波的第一信道的功率压缩因子，以使得第一信道所在的载波工作在高频点时，终端设备可以使用一个较大的功率压缩因子对该第一信道进行压缩，第一信道所在的载波工作在低频点时，终端设备可以使用一个较小的功率压缩因子对其进行压缩。通过这种方式，可以避免第一信道所在的载波工作在低频点时，终端设备仍然采用较大的功率压缩因子对其进行压缩，导致第一信道压缩后的发射功率过小使得发送数据失败的概率较大的问题，提高了第一信道传输数据的效率。In this embodiment, when the frequency points of each carrier are different, the terminal device may first determine a power compression factor of the first channel that is adapted to each carrier according to a frequency point where each carrier is located, When the carrier where the first channel is located is operated at a high frequency point, the terminal device may compress the first channel by using a larger power compression factor. When the carrier where the first channel is located at a low frequency point, the terminal device may use one. A smaller power compression factor compresses it. In this way, when the carrier where the first channel is located is operated at a low frequency point, the terminal device still compresses the signal with a large power compression factor, so that the transmission power after the compression of the first channel is too small, so that the data transmission fails. The problem of high probability increases the efficiency of data transmission on the first channel.

其中，本发明实施例不限定上述终端设备如何根据每个载波所在的频点，确定每个载波的第一信道的功率压缩因子的具体实现方式。可选的，上述终端设备可以根据

来确定每个载波的第一信道的功率压缩因子Power_scaling_factor；其中，上述F表示载波所在的频点，上述B为预设的压缩系数。可选的，上述终端设备还可以根据Power_scaling_factor＝F×B，来确定每个载波的第一信道的功率压缩因子Power_scaling_factor等。The embodiment of the present invention does not limit how the foregoing terminal device determines the specific implementation manner of the power compression factor of the first channel of each carrier according to the frequency point where each carrier is located. Optionally, the foregoing terminal device may be based on

The power compression factor Power_scaling_factor of the first channel of each carrier is determined; where F represents the frequency point where the carrier is located, and B is a preset compression coefficient. Optionally, the foregoing terminal device may further determine a power compression factor Power_scaling_factor or the like of the first channel of each carrier according to Power_scaling_factor=F×B.

第三种情况：上述载波信息为载波所占用的发射功率，则上述S601具体可以包括：终端设备根据每个载波所占用的发射功率，确定每个载波的第一信道的功率压缩因子。The third case: the foregoing carrier information is the transmit power occupied by the carrier, and the foregoing S601 may specifically include: determining, by the terminal device, a power compression factor of the first channel of each carrier according to the transmit power occupied by each carrier.

具体的，如上述实施例所说，上述终端设备可以使用多个载波发送数据，其中，终端设备在每个载波占用的发射功率可以相同，也可以不同。若终端设备在某一载波占用的发射功率较大，则该载波的第一信道的发射功率也较大，若终端设备在某一占用的发射功率较小，则该载波的第一信道的发射功率也较小。然而，现有技术中，终端设备在对其多个载波的某一载波的第一信道进行发射功率压缩时，均采用同一功率压缩因子对其进行压缩，此时，若该第一信道的发射功率较小，则终端设备在使用该功率压缩因子对其发射功率进行压缩后，本身发射功率较小的第一信道易因压缩后的发射功率过小，导致发送数据失败的概率较高。Specifically, as described in the foregoing embodiment, the terminal device may send data by using multiple carriers, where the transmission power occupied by the terminal device on each carrier may be the same or different. If the transmission power of the terminal device occupied by a certain carrier is large, the transmission power of the first channel of the carrier is also large. If the transmission power of the terminal device is smaller, the transmission of the first channel of the carrier is performed. The power is also small. However, in the prior art, when the terminal device performs transmission power compression on the first channel of a certain carrier of multiple carriers, it uses the same power compression factor to compress it. At this time, if the first channel is transmitted, If the power is small, the terminal device compresses the transmit power by using the power compression factor, and the first channel with a small transmit power is easily compressed due to the compressed transmit power. Too small, the probability of failure to send data is high.

而在本实施例中，当上述每个载波第一载波所占用的发射功率不同时，上述终端设备可以根据每个载波所占用的发射功率，先确定适配于该载波的第一信道的功率压缩因子，以使得该载波的第一信道发射功率较大时，终端设备可以使用一个较大的功率压缩因子对其进行压缩，该载波的第一信道发射功率较小时，终端设备可以使用一个较小的功率压缩因子对其进行压缩。通过这种方式，可以避免第一信道发射功率较小时，终端设备仍然采用较大的功率压缩因子对其进行压缩，导致第一信道在使用压缩后的发射功率发送数据失败的概率较大的问题，提高了第一信道传输数据的效率。In this embodiment, when the transmit power occupied by the first carrier of each carrier is different, the terminal device may first determine the power of the first channel that is adapted to the carrier according to the transmit power occupied by each carrier. The compression factor is such that when the first channel transmission power of the carrier is large, the terminal device can compress it by using a larger power compression factor. When the first channel transmission power of the carrier is small, the terminal device can use a comparison. A small power compression factor compresses it. In this way, when the transmit power of the first channel is small, the terminal device still compresses the data with a large power compression factor, which causes the probability that the first channel fails to transmit data after using the compressed transmit power. , improving the efficiency of transmitting data on the first channel.

其中，本发明实施例不限定上述终端设备如何根据每个载波所占用的发射功率，确定每个载波的第一信道的功率压缩因子的具体实现方式。例如：上述终端设备可以根据

来确定每个载波的第一信道的功率压缩因子Power_scaling_factor；其中，上述P_载波表示每个载波所占用的发射功率，上述P_总为第一总发射功率，上述C为预设的压缩系数。The embodiment of the present invention does not limit how the foregoing terminal device determines the specific implementation manner of the power compression factor of the first channel of each carrier according to the transmit power occupied by each carrier. For example: the above terminal device can be based on

The power compression factor Power_scaling_factor of the first channel of each carrier is determined; wherein the P _carrier represents the transmission power occupied by each carrier, and the P is _always the first total transmission power, and the C is a preset compression coefficient.

进一步地，本实施例十一涉及的是在上述终端设备对所有载波的第一信道的发射功率均进行压缩之后，若终端设备的第二总发射功率(即终端设备对每个载波的第一信道的增益因子进行压缩之后的每个载波的发射功率之和)仍大于最大允许发射功率，终端设备对每个载波的第二信道执行非连续发送(Discontinuous Transmission，简称：DTX)的具体过程。则在上述实施例的基础上，上述方法还可以包括：若所述终端设备的第二总发射功率大于终端设备的最大允许发射功率，则终端设备对每个载波的第二信道执行DTX。Further, in the eleventh embodiment, after the terminal device compresses the transmit power of the first channel of all carriers, the second total transmit power of the terminal device (that is, the first device of the terminal device for each carrier) The sum of the transmit power of each carrier after the gain factor of the channel is compressed is still greater than the maximum allowable transmit power, and the terminal device performs a specific process of discontinuous transmission (DTX) for the second channel of each carrier. Then in the above implementation The method may further include: if the second total transmit power of the terminal device is greater than the maximum allowed transmit power of the terminal device, the terminal device performs DTX on the second channel of each carrier.

具体的，现有技术中，若终端设备对所有载波的第一信道的发射功率均进行压缩之后，终端设备的第二总发射功率(即所有载波压缩后的发射功率之和)仍大于最大允许发射功率，则终端设备会对所有载波上的所有信道进行等比压缩，即在保持每个载波的其他信道与该载波的DPCCH之间的功率比不变的基础上，通过压缩所有载波的DPCCH的发射功率，使得每个载波上的其他信道的发射功率相应地被等比压缩。虽然采用这种方式，可以大幅度的降低终端设备的总发射功率，使终端设备的总发射功率小于或等于最大允许发射功率，但是，若某一载波配置有传输语音业务的信道(例如：DPDCH)，则上述终端设备在对所有载波执行上述等比压缩的过程中，也会相应的等比压缩配置有传输终端设备的语音业务的信道(例如：DPDCH)的载波的发射功率，从而等比压缩配置有传输终端设备的语音业务的信道的发射功率，使得传输终端设备的语音业务的信道在使用压缩后的发射功率进行语音业务传输时，传输失败的概率较高，甚至造成掉话。Specifically, in the prior art, if the terminal device compresses the transmit power of the first channel of all carriers, the second total transmit power of the terminal device (that is, the sum of the transmit powers after all carriers are compressed) is still greater than the maximum allowable Transmit power, the terminal equipment will perform equal-compression compression on all channels on all carriers, that is, by compressing the DPCCH of all carriers while maintaining the power ratio between the other channels of each carrier and the DPCCH of the carrier. The transmit power is such that the transmit power of the other channels on each carrier is correspondingly compressed. In this way, the total transmit power of the terminal device can be greatly reduced, so that the total transmit power of the terminal device is less than or equal to the maximum allowable transmit power, but if a certain carrier is configured with a channel for transmitting voice services (for example: DPDCH) The above-mentioned terminal device performs the above-described proportional compression on all the carriers, and correspondingly compresses the transmission power of the carrier of the channel (for example, DPDCH) of the voice service of the transmission terminal device, and thus the ratio The transmission power of the channel for transmitting the voice service of the terminal device is compressed, so that when the channel of the voice service of the transmission terminal device uses the compressed transmission power for voice service transmission, the probability of transmission failure is high, and even dropped calls are caused.

而在本实施例中，若上述终端设备对所有载波的第一信道的发射功率均进行压缩之后，终端设备的第二总发射功率仍大于最大允许发射功率，终端设备可以先不对所有载波执行等比压缩，而是对所有载波上的优先级较低的第二信道执行DTX，以降低终端设备的总发射功率。此时，若上述多个载波中的某一载波配置有传输终端设备的语音业务的信道(例如：DPDCH)，则通过这种方式，可以在降低终端设备的总发射功率的基础上，保证了传输语音业务的信道的功率不被压缩，可以使用终端设备本身设置的发射功率发送数据，使终端设备可以正常传输语音业务。In this embodiment, after the terminal device compresses the transmit power of the first channel of all carriers, the second total transmit power of the terminal device is still greater than the maximum allowable transmit power, and the terminal device may not perform execution on all carriers. Instead of compression, DTX is performed on the second channel of lower priority on all carriers to reduce the total transmit power of the terminal device. In this case, if one of the plurality of carriers is configured with a channel for transmitting voice services of the terminal device (for example, DPDCH), in this way, the total transmit power of the terminal device can be reduced, thereby ensuring The power of the channel for transmitting the voice service is not compressed, and the data can be transmitted using the transmit power set by the terminal device itself, so that the terminal device can normally transmit the voice service.

具体实现时，上述终端设备在此次发送周期不发送每个载波的第二信道所要传输的数据，以降低终端设备的总发射功率，使终端设备的总发射功率可以小于或等于最大允许发射功率。其中，上述第二信道例如可以包括：E-DPDCH、E-DPCCH、HS-DPCCH的信道质量指示(Channel Quality Indicator，简称：CQI)域等中的一个或多个。可选的，终端设备可以对所有载波的E-DPDCH、E-DPCCH、HS-DPCCH的CQI域同时执行DTX，还可以先对所有载波的E-DPDCH执行DTX，若对所有载波的所有E-DPDCH执行完DTX之后，终端设备的总发射功率仍然大于最大允许发射功率，则可以进一步对所有载波的E-DPCCH执行DTX。若对所有载波的E-DPCCH执行完DTX之后，终端设备的总发射功率仍然大于最大允许发射功率，则可以进一步地对所有载波的HS-DPCCH的CQI域部分执行DTX等，以达到终端设备的总发射功率小于或等于最大允许发射功率的目的。In a specific implementation, the terminal device does not transmit data to be transmitted on the second channel of each carrier in the current transmission period, so as to reduce the total transmit power of the terminal device, so that the total transmit power of the terminal device can be less than or equal to the maximum allowable transmit power. . The second channel may include, for example, one or more of a Channel Quality Indicator (CQI) field of the E-DPDCH, the E-DPCCH, and the HS-DPCCH. Optionally, the terminal device can simultaneously perform DTX on the CQI domains of E-DPDCH, E-DPCCH, and HS-DPCCH of all carriers, and can also perform DTX. DTX is performed on the E-DPDCH of all carriers. If the total transmit power of the terminal device is still greater than the maximum allowed transmit power after all D-DPDCHs of all carriers are performed, the DTX can be further performed on the E-DPCCH of all carriers. . If the total transmit power of the terminal device is still greater than the maximum allowable transmit power after the DTX is performed on the E-DPCCH of all carriers, DTX and the like may be further performed on the CQI domain portion of the HS-DPCCH of all carriers to reach the terminal device. The total transmit power is less than or equal to the maximum allowable transmit power.

可选的，在发明的另一实现方式中，上述终端设备还可以采用上述实施例二所示的方式，从多个载波中确定一个发射功率最大的第一载波，从而对该第一载波的第二信道执行DTX。若终端设备在对该第一载波的所有第二信道执行完DTX之后，终端设备当前的总发射功率仍然大于最大允许发射功率，则终端设备可以采用上述实施例二所示的方式，进一步地从除已被执行DTX的第一载波之外的其他载波中，即从未执行DTX的载波中确定第二载波，并对该第二载波的第二信道执行DTX，以此循环，直至终端设备的总发射功率小于或等于最大允许发射功率。其中，上述终端设备可以对第一载波的E-DPDCH、E-DPCCH、HS-DPCCH的CQI域同时执行DTX，还可以先对第一载波的E-DPDCH执行DTX，若对该第一载波的所有E-DPDCH执行完DTX之后，终端设备的总发射功率仍然大于最大允许发射功率，则可以进一步对该第一载波的E-DPCCH执行DTX。若对该第一载波的E-DPCCH执行完DTX之后，终端设备的总发射功率仍然大于最大允许发射功率，则可以进一步地对该第一载波的HS-DPCCH的CQI域部分执行DTX等，本发明对此不进行限定。Optionally, in another implementation manner of the foregoing, the foregoing terminal device may further determine, by using the manner shown in the foregoing Embodiment 2, a first carrier with the largest transmit power from the multiple carriers, thereby The second channel performs DTX. If the terminal device is still performing the DTX on all the second channels of the first carrier, and the current total transmit power of the terminal device is still greater than the maximum allowable transmit power, the terminal device may further adopt the manner shown in the foregoing Embodiment 2, further In addition to the first carrier that has been subjected to DTX, that is, the second carrier is determined from the carrier that has not performed DTX, and the DTX is performed on the second channel of the second carrier, thereby circulating until the terminal device The total transmit power is less than or equal to the maximum allowable transmit power. The terminal device may perform DTX on the E-DPDCH, the E-DPCCH, and the CQI field of the HS-DPCCH of the first carrier at the same time, or perform DTX on the E-DPDCH of the first carrier, if the first carrier is used. After all E-DPDCHs perform DTX, the total transmit power of the terminal device is still greater than the maximum allowed transmit power, and DTX may be further performed on the E-DPCCH of the first carrier. If the total transmit power of the terminal device is still greater than the maximum allowable transmit power after the DTX is performed on the E-DPCCH of the first carrier, the DQ of the CQI domain portion of the HS-DPCCH of the first carrier may be further performed. The invention does not limit this.

可选的，在发明的另一实现方式中，上述终端设备还可以采用现有技术的方式，从多个载波中确定一个DPCCH功率最大的载波，从而对该载波的第二信道执行DTX。若终端设备在对该载波的所有第二信道执行完DTX之后，终端设备当前的总发射功率仍然大于最大允许发射功率，则终端设备可以在从未执行DTX的载波中确定新的DPCCH功率最大的载波，并对该新的DPCCH功率最大的载波的第二信道执行DTX，以此循环，直至终端设备的总发射功率小于或等于最大允许发射功率。其中，上述终端设备对确定的DPCCH功率最大的载波的一个第二信道执行DTX，还是对该载波的所有第二信道执行DTX，具体可以参见上述对第一载波执行DTX的描述，本发明对此不再赘述。Optionally, in another implementation manner of the invention, the foregoing terminal device may further determine, by using a prior art manner, a carrier with the highest DPCCH power from the plurality of carriers, thereby performing DTX on the second channel of the carrier. If the terminal device is still performing the DTX on all the second channels of the carrier, and the current total transmit power of the terminal device is still greater than the maximum allowed transmit power, the terminal device may determine that the new DPCCH power is the largest among the carriers that have never performed DTX. The carrier, and performing DTX on the second channel of the new carrier with the highest DPCCH power, is cycled until the total transmit power of the terminal device is less than or equal to the maximum allowed transmit power. The foregoing terminal device performs DTX on a second channel of the carrier with the highest DPCCH power, or performs DTX on all the second channels of the carrier. For details, refer to the description of performing DTX on the first carrier. I won't go into details here.

本发明实施例提供的发射功率压缩方法，在终端设备对所有载波的第一信道的发射功率进行压缩之后，若终端设备的总发射功率仍然大于最大允许发射功率，终端设备可以进一步地的对所有载波上传输优先级较低的数据信道执行DTX，来降低每个载波的总发射功率，进而降低终端设备的总发射功率。通过这种方式，在多个载波的某一载波配置有传输终端设备的语音业务的信道时，可以在降低终端设备的总发射功率的基础上，保证终端设备可以正常传输终端设备的语音业务。In the transmit power compression method provided by the embodiment of the present invention, after the terminal device compresses the transmit power of the first channel of all carriers, if the total transmit power of the terminal device is still greater than the maximum allowable transmit power, the terminal device may further The data channel with a lower priority transmission on the carrier performs DTX to reduce the total transmit power of each carrier, thereby reducing the total transmit power of the terminal device. In this way, when a certain carrier of the multiple carriers is configured with a channel for transmitting the voice service of the terminal device, the terminal device can normally transmit the voice service of the terminal device on the basis of reducing the total transmission power of the terminal device.

图7A为本发明实施例提供的发射功率压缩方法实施例十二的流程示意图。在本实施例中，上述终端可以配置有多个载波，本实施例十二涉及的是终端设备在对每个载波的第一信道的发射功率进行压缩之后，若终端设备确定终端设备的总发射功率仍大于所述终端设备的最大允许发射功率，且存在至少一个包括第二信道的载波，则终端设备对至少一个载波的第三信道执行DTX的具体过程。如图7A所示，该方法可以包括：FIG. 7 is a schematic flowchart of Embodiment 12 of a method for compressing a transmit power according to an embodiment of the present invention. In this embodiment, the terminal may be configured with multiple carriers, and the twelfth embodiment relates to the terminal device determining the total transmission of the terminal device after compressing the transmit power of the first channel of each carrier. If the power is still greater than the maximum allowed transmit power of the terminal device, and there is at least one carrier including the second channel, the terminal device performs a specific process of DTX on the third channel of the at least one carrier. As shown in FIG. 7A, the method may include:

S701A、若终端设备对所有载波的第一信道的增益因子均进行压缩后，终端设备的总发射功率仍大于终端设备的最大允许发射功率，则终端设备确定至少一个载波的信道资源是否包括用于传输终端设备上的语音业务的第二信道。S701A. If the terminal device compresses the gain factors of the first channel of all the carriers, and the total transmit power of the terminal device is still greater than the maximum allowed transmit power of the terminal device, the terminal device determines whether the channel resources of the at least one carrier are included. The second channel of the voice service on the transmission terminal device.

具体的，现有技术中，若终端设备对所有载波的第一信道的发射功率均进行压缩之后，终端设备的总发射功率(即所有载波压缩后的发射功率之和)仍大于最大允许发射功率，则终端设备会对所有载波上的所有信道进行等比压缩，即在保持每个载波的其他信道与该载波的DPCCH之间的功率比不变的基础上，通过压缩所有载波的DPCCH的发射功率，使得每个载波上的其他信道的发射功率相应地被等比压缩。虽然采用这种方式，可以大幅度的降低终端设备的总发射功率，使终端设备的总发射功率小于或等于最大允许发射功率，但是，若某一载波配置有传输语音业务的第二信道(例如：DPDCH)，则上述终端设备在对所有载波执行上述等比压缩的过程中，也会相应的等比压缩配置有传输终端设备的语音业务的第二信道(例如：DPDCH)的载波的发射功率，从而等比压缩配置有传输终端设备的语音业务的第二信道的发射功率，使得传输终端设备的语音业务的第二信道在使用压缩后的发射功率进行语音业务传输时，传输失败的概率较高，甚至造成掉话。Specifically, in the prior art, if the terminal device compresses the transmit power of the first channel of all carriers, the total transmit power of the terminal device (that is, the sum of the transmit powers after all carriers are compressed) is still greater than the maximum allowable transmit power. Then, the terminal device performs equal-compression compression on all channels on all carriers, that is, by transmitting the DPCCH of all carriers by maintaining the power ratio between the other channels of each carrier and the DPCCH of the carrier unchanged. The power is such that the transmit power of the other channels on each carrier is correspondingly compressed in proportion. In this way, the total transmit power of the terminal device can be greatly reduced, so that the total transmit power of the terminal device is less than or equal to the maximum allowable transmit power, but if a certain carrier is configured with a second channel for transmitting voice services (for example, :DPDCH), in the process of performing the above-mentioned equal-compression compression on all carriers, the terminal device also correspondingly compresses the transmission power of the carrier of the second channel (for example, DPDCH) configured to transmit the voice service of the terminal device. And thus compressing the transmission power of the second channel configured to transmit the voice service of the terminal device, so that the second channel of the voice service of the transmission terminal device is under use pressure When the reduced transmit power is used for voice service transmission, the probability of transmission failure is high, and even dropped calls.

而在本实施例中，在上述终端设备所使用的载波中存在传输语音业务的第二信道时，为了避免因等比压缩导致传输语音业务的第二信道传输失败率高的问题，可以不压缩传输语音业务的第二信道的发射功率，采用对载波的传输优先级较低的数据的第三信道执行DTX的方式来降低终端设备的总发射功率。因此，在上述终端设备对所有载波的第一信道的发射功率均进行压缩之后，若终端设备的总发射功率仍大于最大允许发射功率，则终端设备可以先确定上述多个载波中是否存在包括用于传输终端设备上的语音业务的第二信道的载波，其中，上述所说的第一信道例如可以为E-DPDCH，上述所说的第二信道例如可以为DPDCH。具体实现时，终端设备可以根据每个载波的信道资源配置，确定是否存在配置有第二信道的载波。In this embodiment, when there is a second channel for transmitting a voice service in the carrier used by the terminal device, in order to avoid the problem that the second channel transmission failure rate of the voice service is high due to the proportional compression, the compression may not be compressed. The transmit power of the second channel of the voice service is transmitted, and the total transmit power of the terminal device is reduced by performing DTX on the third channel of the data with lower transmission priority of the carrier. Therefore, after the terminal device compresses the transmit power of the first channel of all the carriers, if the total transmit power of the terminal device is still greater than the maximum allowable transmit power, the terminal device may first determine whether the multiple carriers are included. The carrier of the second channel of the voice service on the transmission terminal device, wherein the first channel may be an E-DPDCH, for example, and the second channel may be a DPDCH. In a specific implementation, the terminal device may determine, according to the channel resource configuration of each carrier, whether a carrier configured with the second channel exists.

S702A、若终端设备确定存在包括第二信道的载波，则终端设备对至少一个载波的第三信道执行非连续发送DTX。S702A. If the terminal device determines that the carrier including the second channel exists, the terminal device performs discontinuous transmission DTX on the third channel of the at least one carrier.

具体的，终端设备在确定其所使用的多个载波中，存在一个或多个包括第二信道的载波时，终端设备可以对其所使用的多个载波中的至少一个载波的第三信道执行DTX，以降低终端设备的总发射功率。其中，上述所说的第三信道例如可以包括：E-DPDCH、E-DPCCH、HS-DPCCH的CQI域等中的一个或多个。可选的，终端设备在对上述至少一个载波的第三信道执行DTX时，可以对该至少一个载波的E-DPDCH、E-DPCCH、HS-DPCCH的CQI域同时执行DTX，还可以先对该至少一个载波的E-DPDCH执行DTX，若对该至少一个载波的E-DPDCH执行完DTX之后，终端设备的总发射功率仍然大于最大允许发射功率，则可以进一步对该至少一个载波的E-DPCCH执行DTX。若对该至少一个载波的E-DPCCH执行完DTX之后，终端设备的总发射功率仍然大于最大允许发射功率，则可以进一步地对该至少一个载波的HS-DPCCH的CQI域部分执行DTX等，本发明对此不进行限定。Specifically, when determining, by the terminal device, that one or more carriers including the second channel exist in the multiple carriers used by the terminal device, the terminal device may perform the third channel of the at least one carrier of the multiple carriers used by the terminal device. DTX to reduce the total transmit power of the terminal equipment. The third channel mentioned above may include, for example, one or more of E-DPDCH, E-DPCCH, CQI domain of HS-DPCCH, and the like. Optionally, when performing the DTX on the third channel of the at least one carrier, the terminal device may simultaneously perform DTX on the CQI domain of the E-DPDCH, the E-DPCCH, and the HS-DPCCH of the at least one carrier, or The E-DPDCH of the at least one carrier performs DTX. If the total transmit power of the terminal device is still greater than the maximum allowed transmit power after performing DTX on the E-DPDCH of the at least one carrier, the E-DPCCH of the at least one carrier may be further Execute DTX. If the total transmit power of the terminal device is still greater than the maximum allowed transmit power after the DTX is performed on the E-DPCCH of the at least one carrier, the DQ, etc. of the CQI domain portion of the HS-DPCCH of the at least one carrier may be further performed. The invention does not limit this.

通过这种方式，可以在降低终端设备的总发射功率的基础上，保证了传输语音业务的信道可以使用终端设备本身设置的发射功率发送数据，使终端设备可以正常传输语音业务，避免掉话的风险，提高了用户体验。In this way, on the basis of reducing the total transmit power of the terminal device, it is ensured that the channel for transmitting the voice service can use the transmit power set by the terminal device to transmit data, so that the terminal device can normally transmit the voice service and avoid the dropped call. Risks that improve the user experience.

本发明实施例提供的发射功率压缩方法，在终端设备对所有载波的第一信道的发射功率进行压缩之后，若终端设备的总发射功率仍然大于最大允许发射功率，且终端设备确定存在包括传输语音业务的第二信道的载波时，终端设备可以对至少一个载波上传输优先级较低的第三信道执行DTX，来降低第一载波的总发射功率，进而降低终端设备的总发射功率。通过这种方式，可以在终端设备配置了语音业务的信道时，可以在降低终端设备的总发射功率的基础上，保证终端设备可以正常传输语音业务。A method for compressing a transmit power provided by an embodiment of the present invention, where the terminal device is the first for all carriers After the transmission power of the channel is compressed, if the total transmit power of the terminal device is still greater than the maximum allowed transmit power, and the terminal device determines that there is a carrier including the second channel for transmitting the voice service, the terminal device may transmit the priority on the at least one carrier. The lower third channel performs DTX to reduce the total transmit power of the first carrier, thereby reducing the total transmit power of the terminal device. In this way, when the terminal device configures the channel of the voice service, the terminal device can normally transmit the voice service on the basis of reducing the total transmit power of the terminal device.

进一步地，在上述实施例的基础上，本实施例十三涉及的是上述终端设备如何对至少一个载波的第三信道执行非连续发送的DTX的具体过程，则上述S702A具体可以分为如下两种情况：Further, on the basis of the foregoing embodiment, the thirteenth embodiment relates to a specific process of how the terminal device performs DTX for discontinuous transmission on the third channel of the at least one carrier, and the foregoing S702A may be specifically divided into the following two. Situation:

第一种情况：终端设备对所有载波的第三信道同时执行DTX。The first case: the terminal device simultaneously performs DTX on the third channel of all carriers.

具体的，在本实施例中，终端设备在确定其所使用的多个载波中，存在一个或多个包括第二信道的载波时，终端设备可以对其所使用的每个载波的第三信道执行DTX，以达到降低终端设备的总发射功率的目的。具体实现时，终端设备可以对所有载波的E-DPDCH、E-DPCCH、HS-DPCCH的CQI域同时执行DTX。终端设备还可以先对所有载波的E-DPDCH执行DTX，若对所有载波的E-DPDCH执行完DTX之后，终端设备的总发射功率仍然大于最大允许发射功率，则可以进一步对所有载波的E-DPCCH执行DTX。若对所有载波的E-DPCCH执行完DTX之后，终端设备的总发射功率仍然大于最大允许发射功率，则可以进一步地对所有载波的HS-DPCCH的CQI域部分执行DTX等，以达到终端设备的总发射功率小于或等于最大允许发射功率的目的。Specifically, in this embodiment, when the terminal device determines that one or more carriers including the second channel exist in the multiple carriers used by the terminal device, the terminal device may use the third channel of each carrier used by the terminal device. DTX is implemented to achieve the purpose of reducing the total transmit power of the terminal device. In a specific implementation, the terminal device can simultaneously perform DTX on the CQI domains of E-DPDCH, E-DPCCH, and HS-DPCCH of all carriers. The terminal device may also perform DTX on the E-DPDCH of all carriers first. If the total transmit power of the terminal device is still greater than the maximum allowed transmit power after performing DTX on the E-DPDCH of all carriers, the E- of all carriers may be further DPCCH performs DTX. If the total transmit power of the terminal device is still greater than the maximum allowable transmit power after the DTX is performed on the E-DPCCH of all carriers, DTX and the like may be further performed on the CQI domain portion of the HS-DPCCH of all carriers to reach the terminal device. The total transmit power is less than or equal to the maximum allowable transmit power.

第二种情况：终端设备从多个载波中确定第一载波，并对第一载波的第三信道执行DTX。The second case: the terminal device determines the first carrier from the plurality of carriers, and performs DTX on the third channel of the first carrier.

具体的，在本实施例中，终端设备在确定其所使用的多个载波中，存在一个或多个包括第二信道的载波时，终端设备可以从其所使用的多个载波中，先确定一个第一载波，并对第一载波的第三信道执行DTX，以达到降低终端设备的总发射功率的目的。可选的，终端设备可以对第一载波的E-DPDCH、E-DPCCH、HS-DPCCH的CQI域同时执行DTX，还可以先对第一载波的E-DPDCH执行DTX，若对该第一载波的所有E-DPDCH执行完DTX之后，终端设备的总发射功率仍然大于最大允许发射功率，则可以进一步对该第一载波的E-DPCCH执行DTX。若对该第一载波的E-DPCCH执行完DTX之后，终端设备的总发射功率仍然大于最大允许发射功率，则可以进一步地对该第一载波的HS-DPCCH的CQI域部分执行DTX等，本发明对此不进行限定。Specifically, in the embodiment, when the terminal device determines that one or more carriers including the second channel exist in the multiple carriers used by the terminal device, the terminal device may first determine the multiple carriers used by the terminal device. A first carrier performs DTX on the third channel of the first carrier to achieve the purpose of reducing the total transmit power of the terminal device. Optionally, the terminal device may perform DTX on the E-DPDCH, the E-DPCCH, and the CQI field of the HS-DPCCH of the first carrier, and may perform DTX on the E-DPDCH of the first carrier, if the first carrier is used. After all E-DPDCHs have completed DTX, the total transmit power of the terminal device is still greater than the maximum allowable transmit power, then one can enter one. Step DTX is performed on the E-DPCCH of the first carrier. If the total transmit power of the terminal device is still greater than the maximum allowable transmit power after the DTX is performed on the E-DPCCH of the first carrier, the DQ of the CQI domain portion of the HS-DPCCH of the first carrier may be further performed. The invention does not limit this.

进一步地，若上述终端设备在对第一载波的所有第三信道执行完DTX之后，终端设备当前的总发射功率仍然大于最大允许发射功率，则终端设备可以进一步地从除已被执行DTX的第一载波之外的其他载波中，即从未执行DTX的载波中确定第二载波，并对该第二载波的第三信道执行DTX，以此循环，直至终端设备的总发射功率小于或等于最大允许发射功率。Further, if the terminal device performs the DTX on all the third channels of the first carrier, and the current total transmit power of the terminal device is still greater than the maximum allowed transmit power, the terminal device may further remove the DTX from the In other carriers than one carrier, that is, the second carrier is determined from the carrier that does not perform DTX, and DTX is performed on the third channel of the second carrier, and the loop is performed until the total transmitting power of the terminal device is less than or equal to the maximum. Allow transmission power.

需要说明的是，本发明实施例不限定上述终端设备从多个载波中确定第一载波的具体实现方式，例如：上述终端设备可以根据每个载波的DPCCH的发射功率，选择DPCCH发射功率最大的载波作为第一载波。可选的，在本发明的另一实现方式中，上述终端设备还可以根据每个载波的载波信息，从多个载波中确定一个第一载波；其中，上述每个载波的载波信息例如可以包括如下任一个：每个载波所在的频点、每个载波的第一信道的传输时间间隔TTI长度、每个载波所占用的发射功率、网络设备为每个载波分配的授权、每个载波的控制信道的发射功率等。例如：上述每个载波的载波信息包括每个载波的频点时，上述终端设备可以根据每个载波所在的频点，确定频点最高的载波为第一载波。例如：上述每个载波的载波信息包括每个载波的第一信道的TTI长度时，上述终端设备可以根据每个载波的第一信道的TTI长度，确定第一信道的TTI长度最大的载波为第一载波。例如：上述每个载波的载波信息包括每个载波所占用的发射功率时，上述终端设备可以根据每个载波所占用的发射功率，确定占用发射功率最大的载波为第一载波。例如：上述每个载波的载波信息包括网络设备为每个载波分配的授权时，上述终端设备可以根据网络设备为每个载波分配的授权，确定授权最大的载波为第一载波。例如：上述每个载波的载波信息包括每个载波的控制信道的发射功率时，上述终端设备可以根据每个载波的控制信道的发射功率，确定控制信道的发射功率最大的载波为第一载波。其中，这里所说的控制信道例如可以为DPCCH。It should be noted that, the embodiment of the present invention does not limit the specific implementation manner in which the foregoing terminal device determines the first carrier from multiple carriers. For example, the terminal device may select the maximum transmit power of the DPCCH according to the transmit power of the DPCCH of each carrier. The carrier acts as the first carrier. Optionally, in another implementation manner of the present invention, the terminal device may further determine a first carrier from multiple carriers according to carrier information of each carrier, where the carrier information of each carrier may include, for example, Any one of the following: the frequency at which each carrier is located, the transmission time interval TTI length of the first channel of each carrier, the transmission power occupied by each carrier, the authorization allocated by the network device for each carrier, and the control of each carrier The transmit power of the channel, etc. For example, when the carrier information of each carrier includes the frequency of each carrier, the terminal device may determine that the carrier with the highest frequency point is the first carrier according to the frequency point where each carrier is located. For example, when the carrier information of each carrier includes the TTI length of the first channel of each carrier, the terminal device may determine that the carrier with the largest TTI length of the first channel is the first according to the TTI length of the first channel of each carrier. One carrier. For example, when the carrier information of each carrier includes the transmit power occupied by each carrier, the terminal device may determine, according to the transmit power occupied by each carrier, that the carrier that occupies the largest transmit power is the first carrier. For example, when the carrier information of each carrier includes an authorization allocated by the network device for each carrier, the terminal device may determine that the carrier with the largest authorization is the first carrier according to the authorization allocated by the network device for each carrier. For example, when the carrier information of each carrier includes the transmit power of the control channel of each carrier, the terminal device may determine, according to the transmit power of the control channel of each carrier, that the carrier with the largest transmit power of the control channel is the first carrier. The control channel referred to herein may be, for example, a DPCCH.

需要说明的是，本发明实施例不限定上述终端设备从从未执行DTX的载波中确定第二载波的具体实现方式，例如可以采用上述所示的确定第一载波的实现方式，本发明对此不再赘述。It should be noted that the embodiment of the present invention does not limit that the foregoing terminal device never performs DTX. For a specific implementation manner of determining the second carrier in the carrier, for example, the implementation manner of determining the first carrier as shown in the foregoing may be used, and the present invention will not be described again.

本发明实施例提供的发射功率压缩方法，在终端设备对所有载波的第一信道的发射功率进行压缩之后，若终端设备的总发射功率仍然大于最大允许发射功率，且终端设备确定存在包括传输语音业务的第二信道的载波时，终端设备可以对至少一个载波上传输优先级较低的第三信道执行DTX，来降低第一载波的总发射功率，进而降低终端设备的总发射功率。通过这种方式，可以在终端设备配置了语音业务的信道时，可以在降低终端设备的总发射功率的基础上，保证终端设备可以正常传输语音业务。The method for compressing a transmit power provided by the embodiment of the present invention, after the terminal device compresses the transmit power of the first channel of all carriers, if the total transmit power of the terminal device is still greater than the maximum allowable transmit power, and the terminal device determines that the transmit voice is included When the carrier of the second channel of the service is used, the terminal device may perform DTX on the third channel with the lower priority of the transmission on the at least one carrier to reduce the total transmit power of the first carrier, thereby reducing the total transmit power of the terminal device. In this way, when the terminal device configures the channel of the voice service, the terminal device can normally transmit the voice service on the basis of reducing the total transmit power of the terminal device.

图7B为本发明实施例提供的发射功率压缩方法实施例十三的流程示意图。在本实施例中，上述终端可以配置有多个载波，本实施例十三涉及的是终端设备在对第一载波的第一信道的发射功率进行压缩之后，若终端设备确定终端设备上存在包括第二信道的载波，且确定第一载波的功率比小于第一预设值，则终端设备对第一载波的第一信道执行非连续发送DTX的具体过程。如图7B所示，该方法可以包括：FIG. 7B is a schematic flowchart of Embodiment 13 of a method for compressing a transmit power according to an embodiment of the present invention. In this embodiment, the terminal may be configured with multiple carriers, and the thirteenth embodiment relates to that after the terminal device compresses the transmit power of the first channel of the first carrier, the terminal device determines that the terminal device is included. And determining, by the carrier of the second channel, that the power ratio of the first carrier is smaller than the first preset value, the terminal device performs a specific process of discontinuously transmitting the DTX to the first channel of the first carrier. As shown in FIG. 7B, the method may include:

S701B、若终端设备的总发射功率大于终端设备的最大允许发射功率，则终端设备从多个载波中确定第一载波，并对第一载波的第一信道的增益因子进行压缩。S701B. If the total transmit power of the terminal device is greater than the maximum allowed transmit power of the terminal device, the terminal device determines the first carrier from the multiple carriers, and compresses the gain factor of the first channel of the first carrier.

具体的，在本实施例中，上述终端设备可以使用多个载波发送上行数据，该多个载波可以为工作在相同频点的载波，也可以为工作在不同频点的载波。其中，上述终端设备所使用的多个载波中的每个载波均配置有至少一个用于传输终端设备的数据业务的第一信道，该第一信道例如可以为上述所说的E-DPDCH等。Specifically, in this embodiment, the terminal device may send uplink data by using multiple carriers, where the multiple carriers may be carriers operating at the same frequency point, or may be carriers operating at different frequency points. Each of the plurality of carriers used by the terminal device is configured with at least one first channel for transmitting data services of the terminal device, and the first channel may be, for example, the E-DPDCH or the like mentioned above.

上述终端设备在使用该多个载波发送上行数据时，会为每个载波的每个信道设置一定的发射功率。具体地，终端设备会为每个载波的DPCCH设置一定的发射功率，为该载波的每个信道设置一个增益因子，该载波上的其他各信道与该载波的DPCCH的功率之比等于该信道的增益因子与DPCCH的增益因子比值的平方，其中，DPCCH对应的增益因子可以为1。每个载波的所有信道的发射功率之和为每个载波的发射功率，所有载波的发射功率之和即为终端设备的总发射功率。在本实施例中，若该第一总发射功率大于终端设备的最大允许发射功率，则终端设备会从多个载波中确定出一个第一载波，并对该第一载波的第一信道的增益因子进行压缩。这里所说的第一信道可以为上述所说的E-DPDCH等。When the terminal device uses the multiple carriers to transmit uplink data, a certain transmit power is set for each channel of each carrier. Specifically, the terminal device sets a certain transmit power for the DPCCH of each carrier, and sets a gain factor for each channel of the carrier, and the ratio of the power of the other channels on the carrier to the DPCCH of the carrier is equal to the channel. The gain factor is the square of the gain factor ratio of the DPCCH, where the gain factor corresponding to the DPCCH can be one. The sum of the transmission powers of all channels of each carrier is the transmission power of each carrier, and the sum of the transmission powers of all carriers is the total transmission power of the terminal equipment. In this embodiment, if the first total transmit power is greater than the terminal design For the maximum allowed transmit power, the terminal device determines a first carrier from the plurality of carriers, and compresses the gain factor of the first channel of the first carrier. The first channel referred to herein may be the aforementioned E-DPDCH or the like.

其中，本实施例不限定上述终端设备从多个载波中确定第一载波的实现方式。具体实现时，上述终端设备可以使用实施例二所示的方式，从多个载波中确定第一载波，还可以采用现有的方式，从多个载波中确定第一载波，对此不再赘述。The embodiment does not limit the implementation manner in which the foregoing terminal device determines the first carrier from multiple carriers. In a specific implementation, the foregoing terminal device may determine the first carrier from multiple carriers by using the method shown in the second embodiment, and may determine the first carrier from multiple carriers in an existing manner, and details are not described herein again. .

其中，本实施例不限定上述终端设备对第一载波的第一信道的增益因子进行压缩的实现方式。具体实现时，上述终端设备可以使用实施例所示的方式，对上述第一载波的第一信道的增益因子进行压缩，还可以采用现有的方式，对上述第一载波的第一信道的增益因子进行压缩，对此不再赘述。The embodiment does not limit the implementation manner in which the terminal device compresses the gain factor of the first channel of the first carrier. In a specific implementation, the terminal device may compress the gain factor of the first channel of the first carrier by using the manner shown in the embodiment, and may also use the existing manner to obtain the gain of the first channel of the first carrier. The factor is compressed and will not be described here.

S702B、若终端设备确定终端设备上存在包括第二信道的载波，且确定第一载波的功率比小于第一预设值，则终端设备对第一载波的第一信道执行非连续发送DTX；其中，第二信道用于传输终端设备上的语音业务，第一载波的功率比为：第一载波的第一信道的压缩后的功率与第一载波的控制信道的功率比。S702. If the terminal device determines that the carrier that includes the second channel exists on the terminal device, and determines that the power ratio of the first carrier is less than the first preset value, the terminal device performs discontinuous transmission of DTX on the first channel of the first carrier. The second channel is used for transmitting a voice service on the terminal device, and the power ratio of the first carrier is: a power ratio of the compressed power of the first channel of the first carrier to the control channel of the first carrier.

具体的，现有技术中，在终端设备对第一载波的第一信道的增益因子进行压缩之后，若第一载波的功率比小于第一预设值，其中第一载波的功率比为：第一载波的第一信道的压缩后的功率与第一载波的控制信道的功率比，则终端设备会将该第一载波功率比设置为一个预设值，也就是说，该第一信道的功率不会被设置为零。此时，若终端设备对所有载波的第一信道的发射功率均进行压缩之后，终端设备的总发射功率(即所有载波压缩后的发射功率之和)仍大于最大允许发射功率，则终端设备会对所有载波上的所有信道进行等比压缩，即在保持每个载波的其他信道与该载波的DPCCH之间的功率比不变的基础上，通过压缩所有载波的DPCCH的发射功率，使得每个载波上的其他信道的发射功率相应地被等比压缩。虽然采用这种方式，可以大幅度的降低终端设备的总发射功率，使终端设备的总发射功率小于或等于最大允许发射功率，但是，若某一载波配置有传输语音业务的第二信道(例如：DPDCH)，则上述终端设备在对所有载波执行上述等比压缩的过程中，也会相应的等比压缩配置有传输终端设备的语音业务的第二信道(例如： DPDCH)的载波的发射功率，从而等比压缩配置有传输终端设备的语音业务的第二信道的发射功率，使得传输终端设备的语音业务的第二信道在使用压缩后的发射功率进行语音业务传输时，传输失败的概率较高，甚至造成掉话。Specifically, in the prior art, after the terminal device compresses the gain factor of the first channel of the first carrier, if the power ratio of the first carrier is less than the first preset value, the power ratio of the first carrier is: The ratio of the compressed power of the first channel of the carrier to the power of the control channel of the first carrier, the terminal device sets the first carrier power ratio to a preset value, that is, the power of the first channel. Will not be set to zero. At this time, if the terminal device compresses the transmit power of the first channel of all carriers, and the total transmit power of the terminal device (that is, the sum of the transmit powers after all carriers are compressed) is still greater than the maximum allowable transmit power, the terminal device may Perform equal-ratio compression on all channels on all carriers, that is, by compressing the transmit power of the DPCCHs of all carriers on the basis of keeping the power ratio between the other channels of each carrier and the DPCCH of the carrier constant, so that each The transmit power of the other channels on the carrier is correspondingly compressed in equal proportions. In this way, the total transmit power of the terminal device can be greatly reduced, so that the total transmit power of the terminal device is less than or equal to the maximum allowable transmit power, but if a certain carrier is configured with a second channel for transmitting voice services (for example, : DPDCH), in the process of performing the above-mentioned proportional compression on all carriers, the above-mentioned terminal device also correspondingly compresses the second channel configured with the voice service of the transmission terminal device (for example: The transmit power of the carrier of the DPDCH), thereby compressing the transmit power of the second channel configured with the voice service of the transport terminal device, so that the second channel of the voice service of the transport terminal device transmits the voice service using the compressed transmit power When the transmission fails, the probability of failure is high, and even the call is dropped.

而在本实施例中，在上述终端设备所使用的载波中存在传输语音业务的第二信道时，为了避免在对所有载波的第一信道的发射功率均进行压缩之后，终端设备的总发射功率(即所有载波压缩后的发射功率之和)仍大于最大允许发射功率，导致终端设备会对所有载波上的所有信道进行等比压缩，使得传输终端设备的语音业务的第二信道在使用压缩后的发射功率进行语音业务传输时，传输失败的概率较高的问题，可以在终端设备确定终端设备上存在包括第二信道的载波，且确定第一载波的功率比小于第一预设值的时候，对第一载波的第一信道执行非连续发送DTX，以降低终端设备的总发射功率。其中，上述第一预设值的大小具体可以根据应用场景或者***配置确定。In this embodiment, when there is a second channel for transmitting a voice service in the carrier used by the terminal device, the total transmit power of the terminal device is avoided after the transmission power of the first channel of all carriers is compressed. (that is, the sum of the transmit powers of all carriers after compression) is still greater than the maximum allowable transmit power, causing the terminal device to perform equal-compression compression on all channels on all carriers, so that the second channel of the voice service of the transmission terminal device is compressed after use. When the transmission power is used for voice service transmission, the probability of transmission failure is high, and the terminal device determines that the carrier including the second channel exists on the terminal device, and determines that the power ratio of the first carrier is less than the first preset value. Discontinuously transmitting DTX to the first channel of the first carrier to reduce the total transmit power of the terminal device. The size of the first preset value may be specifically determined according to an application scenario or a system configuration.

此时，由于第一载波的功率比小于第一预设值，即第一载波的第一信道的压缩后的功率与第一载波的控制信道的功率比小于第一预设值，也就是说，第一载波的第一信道的压缩后的功率较小，使得在使用该压缩后的发射功率在第一信道上发送数据时，发送数据失败的概率较高。因此，在这种情况下，可以放弃发送第一信道的数据，以达到大幅度的压缩第一载波的发射功率的目的，进而可以大幅度的压缩终端设备的总发射功率，以使得终端设备在压缩完第一载波的第一信道的发射功率之后，使终端设备的总发射功率小于或等于终端设备的最大允许发射功率的概率较高，这样，就可以降低了出现终端设备在对所有载波的第一信道的发射功率均进行压缩之后，终端设备的总发射功率(即所有载波压缩后的发射功率之和)仍大于最大允许发射功率，导致终端设备会对所有载波上的所有信道进行等比压缩，使得传输终端设备的语音业务的第二信道在使用压缩后的发射功率进行语音业务传输时，传输失败的概率较高的情况的概率，从而可以使得终端设备的第二信道可以使用原有的发射功率传输语音业务数据，提高了传输可靠性。其中，上述所说的第一载波的控制信道例如可以DPCCH等。At this time, since the power ratio of the first carrier is smaller than the first preset value, that is, the power ratio of the compressed power of the first channel of the first carrier to the control channel of the first carrier is smaller than the first preset value, that is, The compressed power of the first channel of the first carrier is small, so that when the compressed transmit power is used to transmit data on the first channel, the probability of transmitting data failure is high. Therefore, in this case, the data of the first channel can be discarded, so as to achieve a large compression of the transmit power of the first carrier, and the total transmit power of the terminal device can be greatly compressed, so that the terminal device is After the transmission power of the first channel of the first carrier is compressed, the probability that the total transmission power of the terminal device is less than or equal to the maximum allowed transmission power of the terminal device is higher, so that the appearance of the terminal device on all carriers can be reduced. After the transmit power of the first channel is compressed, the total transmit power of the terminal device (ie, the sum of the transmit powers after all carriers are compressed) is still greater than the maximum allowable transmit power, causing the terminal device to perform equal ratios for all channels on all carriers. The probability that the second channel of the terminal device can use the second channel of the terminal device when the second channel of the voice service of the transmission terminal device uses the compressed transmission power to perform voice service transmission, so that the second channel of the terminal device can be used. The transmit power transmits voice service data and improves transmission reliability. The control channel of the first carrier mentioned above may be, for example, a DPCCH or the like.

本发明实施例提供的发射功率压缩方法，终端设备在其总发射功率大于终端设备的最大允许发射功率时，可以从多个载波中确定第一载波，并对第一载波的第一信道的增益因子进行压缩，且在终端设备对第一载波的第一信道的发射功率进行压缩之后，若终端设备确定终端设备上存在包括第二信道的载波，且确定第一载波的功率比小于第一预设值，则终端设备对第一载波的第一信道执行DTX，来降低第一载波的总发射功率，进而降低终端设备的总发射功率。通过这种方式，可以在终端设备配置了语音业务的信道时，可以在降低终端设备的总发射功率的基础上，保证终端设备可以正常传输语音业务。The method for compressing a transmit power provided by the embodiment of the present invention, the total transmit power of the terminal device is greater than When the maximum allowed transmit power of the terminal device, the first carrier may be determined from the plurality of carriers, and the gain factor of the first channel of the first carrier is compressed, and the transmit power of the first channel of the first carrier is used by the terminal device. After performing the compression, if the terminal device determines that the carrier including the second channel exists on the terminal device, and determines that the power ratio of the first carrier is less than the first preset value, the terminal device performs DTX on the first channel of the first carrier to reduce The total transmit power of the first carrier, which in turn reduces the total transmit power of the terminal device. In this way, when the terminal device configures the channel of the voice service, the terminal device can normally transmit the voice service on the basis of reducing the total transmit power of the terminal device.

可选的，在本发明的另一实现方式中，上述S702B具体可以包括：终端设备对第一载波的第一信道和第三信道执行非连续发送DTX。其中，上述所说的第三信道例如可以包括：E-DPCCH、HS-DPCCH的CQI域等中的一个或多个。Optionally, in another implementation manner of the present invention, the foregoing S702B may specifically include: the terminal device performing discontinuous transmission DTX on the first channel and the third channel of the first carrier. The third channel mentioned above may include, for example, one or more of E-DPCCH, CQI domain of HS-DPCCH, and the like.

具体的，鉴于上述E-DPCCH指示的是第一信道的数据所对应的控制信息，因此，在上述终端设备对该载波上所有的第一信道执行DTX时，也可以对上述E-DPCCH进行DTX。更进一步，HS-DPCCH的CQI域用于反映下行信道的信道质量，在某些场景下，若对该HS-DPCCH的CQI域进行DTX，并不会造成太大的影响，因此，也可以进行DTX。也就是说，终端设备可以在对第一载波的所有第一信道执行DTX以后，对上述第三信道同时执行DTX，来进一步地降低第一载波的总发射功率，进而降低终端设备的总发射功率。通过这种方式，可以在终端设备配置了语音业务的信道时，可以在降低终端设备的总发射功率的基础上，保证终端设备可以正常传输语音业务。Specifically, in view of the foregoing E-DPCCH indicating the control information corresponding to the data of the first channel, when the terminal device performs DTX on all the first channels on the carrier, the E-DPCCH may also perform DTX. . Further, the CQI field of the HS-DPCCH is used to reflect the channel quality of the downlink channel. In some scenarios, if the DQ of the CQI field of the HS-DPCCH is not affected, it may also be performed. DTX. That is, the terminal device may perform DTX on the third channel simultaneously after performing DTX on all the first channels of the first carrier, thereby further reducing the total transmit power of the first carrier, thereby reducing the total transmit power of the terminal device. . In this way, when the terminal device configures the channel of the voice service, the terminal device can normally transmit the voice service on the basis of reducing the total transmit power of the terminal device.

其中，上述终端设备对第一载波的第一信道和第三信道执行非连续发送DTX具体实现方式，可以参见上述实施例十一中对于载波的信道执行DTX的描述，还可以采用现有的方式，对此不再赘述。For a specific implementation manner in which the foregoing terminal device performs discontinuous transmission of DTX on the first channel and the third channel of the first carrier, refer to the description of performing DTX on the channel of the carrier in the foregoing Embodiment 11, and may also adopt an existing manner. I will not go into details here.

本发明实施例提供的发射功率压缩方法，终端设备在对第一载波的第一信道执行DTX的同时，还可以对该载波的第三信道也执行DTX，来进一步地降低第一载波的总发射功率，进而降低终端设备的总发射功率。通过这种方式，可以在终端设备配置了语音业务的信道时，可以在降低终端设备的总发射功率的基础上，保证终端设备可以正常传输语音业务。In the method for compressing a transmit power provided by the embodiment of the present invention, the terminal device may perform DTX on the first channel of the first carrier, and may also perform DTX on the third channel of the carrier to further reduce the total transmit of the first carrier. Power, which in turn reduces the total transmit power of the terminal equipment. In this way, when the terminal device configures the channel of the voice service, the terminal device can normally transmit the voice service on the basis of reducing the total transmit power of the terminal device.

图7C为本发明实施例提供的发射功率压缩方法实施例十四的流程示意图。实施例十四涉及的是终端设备在对第一载波的第一信道的发射功率进行压缩之后，若终端设备确定终端设备上不存在包括第二信道的载波，则终端设备从未执行功率压缩的载波中确定第二载波，并对第二载波的第一信道的发射功率进行压缩的具体过程。如图7C所示，在上述S701B之后，该方法可以包括：FIG. 7C is a schematic flowchart of Embodiment 14 of a method for compressing a transmit power according to an embodiment of the present invention; Figure. Embodiment 14 relates to that after the terminal device compresses the transmit power of the first channel of the first carrier, if the terminal device determines that the carrier including the second channel does not exist on the terminal device, the terminal device never performs power compression.

If the terminal device determines that the carrier including the second channel does not exist on the terminal device, and the total transmit power of the terminal device is still greater than the maximum allowed transmit power of the terminal device, the terminal device determines the second carrier from the carrier that performs power compression. .

具体的，在本实施例中，若终端设备确定终端设备上不存在包括第二信道的载波，也就是说，终端设备所使用的所有载波中没有用于传输语音业务的第二信道，此时，若终端设备确定终端设备的总发射功率仍大于终端设备的最大允许发射功率，则终端设备可以从未执行功率压缩的载波中确定第二载波，即从除第一载波之外的其他载波中确定出一个第二载波。其中，本实施例不限定上述终端设备从执行功率压缩的载波中确定第二载波的实现方式。具体实现时，上述终端设备可以使用实施例二所示的方式，从执行功率压缩的载波确定第二载波，还可以采用现有的方式，从执行功率压缩的载波中确定第二载波，对此不再赘述。Specifically, in this embodiment, if the terminal device determines that the carrier including the second channel does not exist on the terminal device, that is, the second channel used for transmitting the voice service is not included in all the carriers used by the terminal device, If the terminal device determines that the total transmit power of the terminal device is still greater than the maximum allowed transmit power of the terminal device, the terminal device may determine the second carrier from the carrier that does not perform power compression, that is, from other carriers than the first carrier. A second carrier is determined. The embodiment does not limit the implementation manner in which the terminal device determines the second carrier from the carrier that performs power compression. In a specific implementation, the foregoing terminal device may determine the second carrier from the carrier that performs power compression, and determine the second carrier from the carrier that performs power compression in an existing manner. No longer.

具体的，终端设备确定第二载波之后，可以对第二载波的第一信道的增益因子进行压缩。其中，本实施例不限定上述终端设备对第二载波的第一信道的增益因子进行压缩的实现方式。具体实现时，上述终端设备可以使用实施例所示的方式，对上述第二载波的第一信道的增益因子进行压缩，还可以采用现有的方式，对上述第二载波的第一信道的增益因子进行压缩，对此不再赘述。Specifically, after the terminal device determines the second carrier, the gain factor of the first channel of the second carrier may be compressed. The embodiment does not limit the implementation manner in which the terminal device compresses the gain factor of the first channel of the second carrier. In a specific implementation, the terminal device may compress the gain factor of the first channel of the second carrier by using the manner shown in the embodiment, and may also use the existing manner to obtain the gain of the first channel of the second carrier. The factor is compressed and will not be described here.

上述终端设备在压缩该第二载波的发射功率之后，若终端设备当前的压缩后的总发射功率小于或等于最大允许发射功率，则终端设备就可以使用该多个载波，通过该当前的总发射功率发送数据。若终端设备当前的总发射功率仍然大于最大允许发射功率，则终端设备可以进一步地再从除已被压缩发射功率的第一载波和第二载波之外的其他载波中，即从未执行功率压缩的载波中再确定出一个第二载波，并对该第二载波的第一信道的发射功率进行压缩，即再次执行上述S701C-S702C，以此循环，直至终端设备的总发射功率小于或等于最大允许发射功率，从而使得终端设备可以使用该多个载波发送数据。After the terminal device compresses the transmit power of the second carrier, if the current compressed total transmit power of the terminal device is less than or equal to the maximum allowable transmit power, the terminal device may use the multiple carriers to pass the current total transmit. Power sends data. If the current total transmit power of the terminal device is still greater than the maximum allowed transmit power, the terminal device may further re-execute power compression from other carriers than the first carrier and the second carrier that have been compressed transmit power. And determining a second carrier in the carrier, and transmitting the first channel of the second carrier The shot power is compressed, that is, the above S701C-S702C is executed again, and the loop is performed until the total transmit power of the terminal device is less than or equal to the maximum allowable transmit power, so that the terminal device can use the multiple carriers to transmit data.

The total transmit power is less than or equal to the maximum allowed transmit power, such that the terminal device can transmit data using the plurality of carriers. By selecting one carrier one by one to perform transmission power compression, the terminal device can greatly compress the transmission power of the carrier when compressing the transmission power of each carrier, thereby greatly compressing the total transmission of the terminal device. The power is such that after the terminal device compresses the transmit power of the first channel of the carrier, the total transmit power of the terminal device is less than or equal to the maximum allowable transmit power of the terminal device, and the compression effect of the transmit power is improved.

图7D为本发明实施例提供的发射功率压缩方法实施例十五的流程示意图。实施例十五涉及的是终端设备在对第一载波的第一信道执行非连续发送DTX之后，若终端设备的总发射功率仍大于终端设备的最大允许发射功率，则终端设备从未执行功率压缩的载波中确定第三载波，并对第三载波的第一信道的发射功率进行压缩的具体过程。如图7D所示，在上述S702B之后，该方法可以包括：FIG. 7 is a schematic flowchart of Embodiment 15 of a method for compressing a transmit power according to an embodiment of the present invention. Embodiment 15 relates to that after the terminal device performs discontinuous transmission of DTX on the first channel of the first carrier, if the total transmit power of the terminal device is still greater than the maximum allowed transmit power of the terminal device, the terminal device never performs power compression. The specific process of determining the third carrier in the carrier and compressing the transmit power of the first channel of the third carrier. As shown in FIG. 7D, after the above S702B, the method may include:

S701D、若终端设备的总发射功率仍大于终端设备的最大允许发射功率，则终端设备从未执行功率压缩的载波中确定第三载波，并对第三载波的第一信道的增益因子进行压缩。S701D. If the total transmit power of the terminal device is still greater than the maximum allowed transmit power of the terminal device, the terminal device determines the third carrier from the carrier that does not perform power compression, and compresses the gain factor of the first channel of the third carrier.

具体的，终端设备在对第一载波的第一信道执行非连续发送DTX之后，若终端设备确定当前被压缩后的总发射功率仍然大于终端设备的最大允许发射功率，则终端设备可以从未执行功率压缩的载波中确定第三载波，并对第三载波的第一信道的增益因子进行压缩。Specifically, after the terminal device performs discontinuous transmission of DTX on the first channel of the first carrier, if the terminal device determines that the total transmitted power after being compressed is still greater than the maximum allowed transmit power of the terminal device, the terminal device may never execute. The third carrier is determined in the power compressed carrier, and the gain factor of the first channel of the third carrier is compressed.

其中，本实施例不限定上述终端设备从执行功率压缩的载波中确定第三载波的实现方式。具体实现时，上述终端设备可以使用实施例二所示的方式，从未执行功率压缩的载波确定第三载波，还可以采用现有的方式，从未执行功率压缩的载波中确定第三载波，对此不再赘述。The embodiment does not limit the implementation manner in which the terminal device determines the third carrier from the carrier that performs power compression. In a specific implementation, the foregoing terminal device can use the method shown in the second embodiment. For example, the third carrier is determined by the carrier that does not perform the power compression, and the third carrier is determined by using the existing method, and the third carrier is not determined.

其中，本实施例不限定上述终端设备对第三载波的第一信道的增益因子进行压缩的实现方式。具体实现时，上述终端设备可以使用实施例所示的方式，对上述第三载波的第一信道的增益因子进行压缩，还可以采用现有的方式，对上述第三载波的第一信道的增益因子进行压缩，对此不再赘述。The embodiment does not limit the implementation manner in which the terminal device compresses the gain factor of the first channel of the third carrier. In a specific implementation, the terminal device may compress the gain factor of the first channel of the third carrier by using the manner shown in the embodiment, and may also use the existing manner to obtain the gain of the first channel of the third carrier. The factor is compressed and will not be described here.

S702D、若终端设备确定终端设备上存在包括第二信道的载波，且确定第三载波的功率比小于第二预设值，则终端设备对第三载波的第一信道执行非连续发送DTX；其中，第三载波的功率比为：第三载波的第一信道的压缩后的功率与第三载波的控制信道的功率比。S702D. If the terminal device determines that the carrier including the second channel exists on the terminal device, and determines that the power ratio of the third carrier is less than a second preset value, the terminal device performs discontinuous transmission of DTX on the first channel of the third carrier; The power ratio of the third carrier is: a power ratio of the compressed power of the first channel of the third carrier to the control channel of the third carrier.

具体的，终端设备在对第三载波的第一信道的增益因子进行压缩之后，若终端设备确定终端设备上存在包括第二信道的载波，且确定第三载波的功率比小于第二预设值，则终端设备对第三载波的第一信道执行非连续发送DTX，以降低终端设备的总发射功率。其中，上述第二预设值可以为与第一预设值相同的值，也可以为不同的值，具体可以根据第三载波的配置确定。Specifically, after the terminal device compresses the gain factor of the first channel of the third carrier, if the terminal device determines that the carrier including the second channel exists on the terminal device, and determines that the power ratio of the third carrier is less than the second preset value The terminal device performs discontinuous transmission of DTX on the first channel of the third carrier to reduce the total transmit power of the terminal device. The second preset value may be the same value as the first preset value, or may be a different value, and may be determined according to the configuration of the third carrier.

此时，由于第三载波的功率比小于第二预设值，即第三载波的第一信道的压缩后的功率与第三载波的控制信道的功率比小于第二预设值，也就是说，第三载波的第一信道的压缩后的功率较小，使得在使用该压缩后的发射功率在第一信道上发送数据时，发送数据失败的概率较高。因此，在这种情况下，可以放弃发送第一信道的数据，以达到大幅度的压缩第三载波的发射功率的目的，进而可以大幅度的压缩终端设备的总发射功率，以使得终端设备在压缩完第三载波的第一信道的发射功率之后，使终端设备的总发射功率小于或等于终端设备的最大允许发射功率的概率较高，这样，就可以降低了出现终端设备在对所有载波的第一信道的发射功率均进行压缩之后，终端设备的总发射功率(即所有载波压缩后的发射功率之和)仍大于最大允许发射功率，导致终端设备会对所有载波上的所有信道进行等比压缩，使得传输终端设备的语音业务的第二信道在使用压缩后的发射功率进行语音业务传输时，传输失败的概率较高的情况的概率，从而可以使得终端设备的第二信道可以使用原有的发射功率传输语音业务数据，提高了传输可靠性。At this time, since the power ratio of the third carrier is smaller than the second preset value, that is, the power ratio of the compressed power of the first channel of the third carrier to the control channel of the third carrier is smaller than the second preset value, that is, The compressed power of the first channel of the third carrier is small, so that when the compressed transmit power is used to transmit data on the first channel, the probability of transmitting data failure is high. Therefore, in this case, the data of the first channel can be discarded, so as to achieve a large compression of the transmit power of the third carrier, and the total transmit power of the terminal device can be greatly compressed, so that the terminal device is After the transmission power of the first channel of the third carrier is compressed, the probability that the total transmission power of the terminal device is less than or equal to the maximum allowed transmission power of the terminal device is higher, so that the appearance of the terminal device on all carriers can be reduced. After the transmit power of the first channel is compressed, the total transmit power of the terminal device (ie, the sum of the transmit powers after all carriers are compressed) is still greater than the maximum allowable transmit power, causing the terminal device to perform equal ratios for all channels on all carriers. The probability that the second channel of the terminal device can use the second channel of the terminal device when the second channel of the voice service of the transmission terminal device uses the compressed transmission power to perform voice service transmission, so that the second channel of the terminal device can be used. The transmit power transmits voice service data and improves transmission reliability.

上述终端设备在进一步地通过执行DTX，压缩该第三载波的发射功率之后，若终端设备当前的压缩后的总发射功率小于或等于最大允许发射功率，则终端设备就可以使用该多个载波，通过该当前的总发射功率发送数据。若终端设备当前的总发射功率仍然大于最大允许发射功率，则终端设备可以进一步地再从除已被压缩发射功率的第一载波和第三载波之外的其他载波中，即从未执行功率压缩的载波中再确定出一个第三载波，并对该第三载波的第一信道的发射功率进行压缩，即再次执行上述S701D-S702D，以此循环，直至终端设备的总发射功率小于或等于最大允许发射功率，从而使得终端设备可以使用该多个载波发送数据。The terminal device further compresses the transmit power of the third carrier by performing DTX Then, if the current compressed total transmit power of the terminal device is less than or equal to the maximum allowable transmit power, the terminal device may use the multiple carriers to transmit data by using the current total transmit power. If the current total transmit power of the terminal device is still greater than the maximum allowed transmit power, the terminal device may further re-execute power compression from other carriers than the first carrier and the third carrier that have been compressed transmit power. A third carrier is further determined in the carrier, and the transmit power of the first channel of the third carrier is compressed, that is, the foregoing S701D-S702D is executed again, and the loop is performed until the total transmit power of the terminal device is less than or equal to the maximum. The transmit power is allowed to be enabled so that the terminal device can transmit data using the plurality of carriers.

本发明实施例提供的发射功率压缩方法，终端设备在对第一载波的第一信道的发射功率进行压缩之后，若终端设备的总发射功率仍然大于最大允许发射功率，终端设备可以进一步地的从未执行功率压缩的载波中确定第三载波，对第三载波的发射功率进行压缩，并以此循环，直至终端设备的总发射功率小于或等于最大允许发射功率，从而使得终端设备可以使用该多个载波发送数据。通过这种逐一选择一个载波执行发射功率压缩的方式，使得终端设备在压缩每个载波的发射功率时，均可以大幅度的压缩该载波的发射功率，进而可以大幅度的压缩终端设备的总发射功率，以使得终端设备在压缩完该载波的第一信道的发射功率之后，终端设备的总发射功率小于或等于终端设备的最大允许发射功率的概率较高，提高了发射功率的压缩效果，也提高了终端设备发送数据的效率。The method for compressing the transmit power provided by the embodiment of the present invention, after the terminal device compresses the transmit power of the first channel of the first carrier, if the total transmit power of the terminal device is still greater than the maximum allowable transmit power, the terminal device may further The third carrier is determined in the carrier that does not perform power compression, and the transmit power of the third carrier is compressed, and is cycled until the total transmit power of the terminal device is less than or equal to the maximum allowable transmit power, so that the terminal device can use the multiple The carrier transmits data. By selecting one carrier one by one to perform transmission power compression, the terminal device can greatly compress the transmission power of the carrier when compressing the transmission power of each carrier, thereby greatly compressing the total transmission of the terminal device. The power is such that after the terminal device compresses the transmit power of the first channel of the carrier, the total transmit power of the terminal device is less than or equal to the maximum allowable transmit power of the terminal device, and the compression effect of the transmit power is improved.
