Description

通信方法及装置Communication method and device

技术领域Technical field

本申请涉及通信技术领域，尤其涉及一种通信方法及装置。The present application relates to the field of communication technologies, and in particular, to a communication method and device.

背景技术Background technique

一般地，终端设备可以支持双卡，其中一个为主卡，一个为副卡。在使用具有双卡的UE时，会出现如下场景：如主卡处于激活(active)状态，副卡处于非连续接收(discontinuous reception，DRX)周期。具体的，DRX周期可以包括UE处于空闲(idle)状态时，基站为该UE配置的一个周期。在该一个周期内，UE可在固定时间醒来接收寻呼(paging)消息以及下行参考信号等。如图1所示，其中，on的部分可代表UE醒来接收下行信号的时间(也称为激活期)，off的部分可代表UE不接收下行信号的时间(也称为睡眠期)。Generally, a terminal device can support dual cards, one of which is a primary card and one is a secondary card. When using a UE with dual cards, the following scenario occurs: if the primary card is in an active state, the secondary card is in a discontinuous reception (DRX) cycle. Specifically, the DRX cycle may include a cycle configured by the base station for the UE when the UE is in an idle state. In this period, the UE may wake up at a fixed time to receive a paging message and a downlink reference signal. As shown in FIG. 1, an on part may represent a time when the UE wakes up to receive a downlink signal (also referred to as an active period), and an off part may represent a time when the UE does not receive a downlink signal (also referred to as a sleep period).

同时，当终端设备装备有多根天线时，可以开启天线选择功能，提升通信性能。当主卡要做天线选择时，会使用不同的天线进行探测参考信号(sounding reference signal，SRS)轮发。假设UE中包括两个天线为天线1和天线2，则在副卡处于如图1所示的off状态时，主卡可以正常进行SRS轮发。但是当副卡处于如图1所示的on状态时，副卡需要使用一根天线接收寻呼消息，此时主卡不能任意使用两根天线，因此会影响主卡轮发SRS，继而导致基站进行信道估计的准确度低下。At the same time, when the terminal equipment is equipped with multiple antennas, the antenna selection function can be enabled to improve communication performance. When the main card is to select antennas, different antennas are used for sounding reference signal (SRS) rotation. Assume that the UE includes two antennas: antenna 1 and antenna 2. When the secondary card is in the off state as shown in FIG. 1, the main card can perform SRS round transmission normally. However, when the secondary card is in the on state as shown in FIG. 1, the secondary card needs to use one antenna to receive the paging message. At this time, the main card cannot use two antennas arbitrarily, so it will affect the main card's rotation of SRS, and then cause the base station. The accuracy of channel estimation is low.

发明内容Summary of the Invention

本申请实施例中，第一时间区间可包括第二终端设备的非连续接收DRX周期的空闲状态的睡眠期，在该第一时间区间内该第二终端设备可能不需要使用天线；在第二时间区间内，即该第二时间区间可包括第二终端设备的DRX周期的空闲状态的激活期，该第二终端设备可能需要使用天线如目标天线，因此，在该第二时间区间内第一终端设备可能无法正常使用该目标天线进行轮发，从而第一终端设备通过向第一网络设备发送SRS指示信息，可使得第一网络设备得知该第一终端设备发送SRS的天线是哪些，进而使得第一网络设备能够准确地进行信道估计。In the embodiment of the present application, the first time interval may include a sleep period in which the second terminal device receives the idle state of the DRX cycle discontinuously, and the second terminal device may not need to use an antenna during the first time interval; In the time interval, that is, the second time interval may include an idle period of the DRX cycle of the second terminal device, the second terminal device may need to use an antenna such as a target antenna.

可理解，本申请实施例中，在第一终端设备所连接的第一网络设备和第二终端设备所连接的第二网络设备相同的情况下，本申请实施例所提供的通信方法可应用于图3所示的通信***。在第一网络设备与第二网络设备不同的情况下，本申请实施例所提供的通信方法可应用于图2所示的通信***。更进一步地，比如第一终端设备和第二终端设备同属于同一个运营商，则本申请实施例所提供的通信方法可应用于图3所示的通信***，而第一终端设备和第二终端设备属于不同的运营商，则该通信方法可应用于图2所示的通信***。It can be understood that, in the embodiment of the present application, when the first network device connected to the first terminal device and the second network device connected to the second terminal device are the same, the communication method provided in the embodiment of the present application can be applied to The communication system shown in FIG. 3.

在图2和图3所示的通信***中，当基站与UE之间有数据需要传输的情况下，UE需要向基站发送SRS，基站根据接收到的SRS，进行上行信道估计。然后基站根据上行信道估计的结果，决定UE进行上行数据传输时可使用的端口号，以及使用的预编码矩阵。进而UE使用该预编码矩阵对上行数据进行处理，以及在该端口号对应的天线端口上发送对应的上行数据。其中，上行数据包括语音，各种应用的数据包，高层信令等等，本申请不作限定。如图4a所示，图4a是本申请实施例提供的一种信道估计方法的示意图。In the communication system shown in FIG. 2 and FIG. 3, when data needs to be transmitted between the base station and the UE, the UE needs to send an SRS to the base station, and the base station performs uplink channel estimation based on the received SRS. Then, the base station determines the port number that can be used by the UE for uplink data transmission and the precoding matrix used according to the result of the uplink channel estimation. Furthermore, the UE uses the precoding matrix to process the uplink data, and sends the corresponding uplink data on the antenna port corresponding to the port number. The uplink data includes voice, data packets of various applications, high-level signaling, and the like, which are not limited in this application. As shown in FIG. 4a, FIG. 4a is a schematic diagram of a channel estimation method according to an embodiment of the present application.

可理解，在时分双工(time division duplexing，TDD)***中，由于上行信道和下行信道具有互易性，因此，基站可以根据接收到的SRS进行上行信道估计后，利用信道互易性进行下行信道估计。然后基站根据下行信道估计的结果，决定UE进行下行数据传输时可使用的端口号，以及使用的预编码矩阵。进而UE在该端口号对应的天线端口上接收对应的下行数据，以及使用该预编码矩阵对下行数据进行处理。其中，下行数据包括语音，各种应用的数据包，高层信令等等，本申请不作限定。如图4b所示，图4b是本申请实施例提供的另一种信道估计方法的示意图。Understandably, in a time division duplex (TDD) system, since the uplink channel and the downlink channel have reciprocity, the base station can perform uplink channel estimation based on the received SRS, and then use the channel reciprocity to perform downlink. Channel estimation. Then, the base station determines a port number that can be used by the UE for downlink data transmission and a precoding matrix to be used according to a result of downlink channel estimation. Furthermore, the UE receives the corresponding downlink data on the antenna port corresponding to the port number, and uses the precoding matrix to process the downlink data. The downlink data includes voice, data packets of various applications, high-level signaling, and the like, which are not limited in this application. As shown in FIG. 4b, FIG. 4b is a schematic diagram of another channel estimation method according to an embodiment of the present application.

进一步地，在LTE技术以及新无线(new radio，NR)技术中，为了增强上行传输性能，引入了上行天线选择的机制。如图5所示，图5是本申请实施例提供的一种电路结构的示意图。如图5所示，UE中的电路结构可包括基带芯片和射频(radio frequency，RF)链路。其中，当UE需要通过天线发送数据时，基带芯片可用于处理数据并生成基带信号，以及输出该基带信号至射频链路，射频链路将该基带信号进行射频处理后将射频信号通过天线以电磁波的形式向外发送。Further, in the LTE technology and the new wireless (new radio (NR)) technology, in order to enhance uplink transmission performance, an uplink antenna selection mechanism is introduced. As shown in FIG. 5, FIG. 5 is a schematic diagram of a circuit structure provided by an embodiment of the present application. As shown in FIG. 5, the circuit structure in the UE may include a baseband chip and a radio frequency (RF) link. Among them, when the UE needs to send data through the antenna, the baseband chip can be used to process the data and generate a baseband signal, and output the baseband signal to a radio frequency link. The form is sent outward.

其中，一个UE中可能会装备多个天线，一种实现方式中，射频链路可通过开关与其中一个或多个天线相连。由于不同天线到基站之间的信道状态可能有较大区别(比如手持电话时，被手遮挡的天线与未被遮挡的天线相比，到基站的信道状态会差距比较大)，所以在发送上行信号时，可以选择信道状态比较好的天线进行发送。Among them, a UE may be equipped with multiple antennas. In one implementation, a radio frequency link may be connected to one or more antennas through a switch. Because the channel status of different antennas to the base station may have a large difference (for example, when a handheld phone is used, the channel status of the antenna blocked by the hand is larger than that of the unblocked antenna). When transmitting signals, you can select an antenna with a better channel status to send.

以上便是关于上行天线选择的描述。同时为了筛选出信道状态比较好的天线，通常的做法是，使用不同的天线发送SRS。比如，UE依次使用不同的天线发送SRS，基站在接收到UE通过不同的天线发送的SRS后，会依次进行信道估计，然后筛选出信道状态较好的一个。进而使得UE在发送上行数据时，就可以使用信道状态较好的天线发送。This concludes the description of uplink antenna selection. At the same time, in order to screen out antennas with better channel status, the usual practice is to use different antennas to send SRS. For example, the UE sends SRS using different antennas in sequence. After receiving the SRS sent by the UE through different antennas, the base station performs channel estimation in order, and then selects the one with a better channel state. Furthermore, when the UE sends uplink data, it can use an antenna with a better channel state to send.

然而，在实际应用中，终端设备常常会包括主卡和副卡，也就是说，在以上所描述的场景下，如主卡分别使用不同的天线发送SRS，且基站配置了主卡通过不同的天线轮发SRS。举例来说，如图6所示，基站配置了主卡通过天线1发送SRS1，以及通过天线2发送SRS2，则在副卡处于DRX周期的空闲状态的激活期的情况下，副卡就需要使用天线如天线2，则主卡便无法通过天线2发送SRS2，这时，如果主卡在应该发送SRS2的情况下使用了天线1发送SRS2，则基站在进行上行信道估计时，实际估计的是天线1到基站的信道状态，但基站误以为是天线2到基站的信道状态，由此会引发信道估计不准确的问题。However, in practical applications, the terminal device often includes a primary card and a secondary card. That is, in the scenario described above, if the primary card uses different antennas to send SRS, and the base station is configured with the primary card to pass different The antenna sends SRS. For example, as shown in FIG. 6, the base station is configured to send SRS1 through antenna 1 and SRS2 through antenna 2. If the secondary card is in the active state of the idle state of the DRX cycle, the secondary card needs to be used. If the antenna is antenna 2, the main card cannot send SRS2 through antenna 2. At this time, if the main card uses antenna 1 to send SRS2 when SRS2 should be sent, the base station actually estimates the antenna when performing uplink channel estimation The channel state from 1 to the base station, but the base station mistakenly believes that it is the channel state from antenna 2 to the base station, which will cause the problem of inaccurate channel estimation.

或者，在副卡使用天线2时，主卡不发送SRS2，该情况下，基站进行上行信道估计时，可能会将接收到的噪声信号或干扰信号作为SRS2，由此同样引发信道估计不准确的问题。Or, when the secondary card uses antenna 2, the primary card does not send SRS2. In this case, when the base station performs uplink channel estimation, the received noise signal or interference signal may be used as SRS2, which also causes inaccurate channel estimation. problem.

同时在第一网络设备与第二网络设备不同的情况下，很大程度上会导致第一网络设备和第二网络设备无法通过网络设备之间的Xn接口如X2来进行通信，由此还会导致网络设备之间无法及时得知彼此的配置。At the same time, if the first network device is different from the second network device, it will largely cause the first network device and the second network device to fail to communicate through the Xn interface such as X2 between the network devices. As a result, network devices cannot know each other's configuration in a timely manner.

因此，为了解决以上问题，本申请实施例提供了一种通信方法，即第一终端设备(包括主卡)在发现第二终端设备(副卡)需要使用天线的情况下，该第一终端设备可向第一网络设备发送SRS指示信息，使得该第一网络设备及时了解第一终端设备使用的天线状况，从而一方面可使得UE正常发送SRS，另一方面，还可提高基站信道估计的准确性。Therefore, in order to solve the above problem, an embodiment of the present application provides a communication method, that is, when the first terminal device (including the primary card) finds that the second terminal device (the secondary card) needs to use an antenna, the first terminal device The SRS indication information can be sent to the first network device, so that the first network device knows the antenna condition used by the first terminal device in time, so that on the one hand, the UE can send SRS normally, and on the other hand, it can improve the accuracy of the base station channel estimation. Sex.

在介绍本申请实施例所提供的通信方法之前，参见图7，图7是本申请实施例提供的另一种电路结构的示意图，如图7所示，该电路结构包括基带芯片以及至少两个射频链路如第一射频链路和第二射频链路。具体的，第一终端设备可使用第一射频链路来发送和/或接收数据、信令等等，第二终端设备可使用第二射频链路发送和/或接收数据、信令等等。也就是说，在第一终端设备需要通过天线发送数据时，基带芯片将生成的基带信号输出至第一射频链路，该第一射频链路将该基带信号进行射频处理后向外发送。在第二终端设备需要通过天线发送数据时，基带芯片将生成的基带信号输出至第二射频链路，该第二射频链路将该基带信号进行射频处理后向外发送。Before introducing the communication method provided by the embodiment of the present application, refer to FIG. 7, which is a schematic diagram of another circuit structure provided by the embodiment of the present application. As shown in FIG. 7, the circuit structure includes a baseband chip and at least two The radio frequency link is a first radio frequency link and a second radio frequency link. Specifically, the first terminal device may use the first radio frequency link to send and / or receive data, signaling, etc., and the second terminal device may use the second radio frequency link to send and / or receive data, signaling, etc. That is, when the first terminal device needs to send data through the antenna, the baseband chip outputs the generated baseband signal to the first radio frequency link, and the first radio frequency link performs radio frequency processing on the baseband signal and sends it out. When the second terminal device needs to send data through the antenna, the baseband chip outputs the generated baseband signal to a second radio frequency link, and the second radio frequency link performs radio frequency processing on the baseband signal and sends it out.

可理解，该第一终端设备可为图2所示的UE11(或者UE12)，该第二终端设备可为图2所示的UE21(或者UE22)。或者，该第一终端设备还可为图3所示的UE31，该第二终端设备还可为图3所示的UE32。It can be understood that the first terminal device may be UE11 (or UE12) shown in FIG. 2, and the second terminal device may be UE21 (or UE22) shown in FIG. 2. Alternatively, the first terminal device may also be UE31 shown in FIG. 3, and the second terminal device may also be UE32 shown in FIG.

图8是本申请实施例提供的一种通信方法的流程示意图，该通信方法可应用于图2或图3所示的通信***。如图8所示，该通信方法包括：FIG. 8 is a schematic flowchart of a communication method according to an embodiment of the present application. The communication method may be applied to the communication system shown in FIG. 2 or FIG. 3. As shown in FIG. 8, the communication method includes:

801、第一终端设备向第一网络设备发送探测参考信号SRS指示信息，该第一网络设备接收来自该第一终端设备的该SRS指示信息。801. A first terminal device sends probe reference signal SRS indication information to a first network device, and the first network device receives the SRS indication information from the first terminal device.

其中，SRS指示信息用于指示第一时间区间和第二时间区间，该第一时间区间为使用第一数量的天线发送SRS的时间区间，该第二时间区间为使用第二数量的天线发送SRS的时间区间，该第一数量大于该第二数量。The SRS indication information is used to indicate a first time interval and a second time interval, where the first time interval is a time interval for sending SRS using a first number of antennas, and the second time interval is a time interval for sending SRS using a second number of antennas. Time interval, the first number is greater than the second number.

本申请实施例中，第一时间区间可对应于第二终端设备的DRX周期的空闲状态的休眠期，即对应于图1所示的off周期。第二时间区间可对应于第二终端设备的DRX周期的空闲状态的激活期，即对应于图1所示的on周期。进一步地，在第一时间区间内第二终端设备由于处于off周期，因此不需要使用天线，而在第二时间区间内第二终端设备由于处于on周期，因此需要使用至少一个天线如目标天线。其中，该目标天线属于第一数量的天线中的天线，但不属于第二数量的天线中的天线，可选的，该目标天线可为一个天线或多个天线。由此，使得第一终端设备在原本应该使用第一数量的天线来发送SRS的情况下，只能通过第二数量的天线来发送SRS，其中，第一数量大于第二数量。In the embodiment of the present application, the first time interval may correspond to the sleep period of the idle state of the DRX cycle of the second terminal device, that is, the off period shown in FIG. 1. The second time interval may correspond to the active period of the idle state of the DRX cycle of the second terminal device, that is, corresponds to the on cycle shown in FIG. 1. Further, since the second terminal device is in the off period in the first time interval, it does not need to use an antenna, and because the second terminal device is in the on period in the second time interval, it needs to use at least one antenna such as a target antenna. The target antenna belongs to the antenna in the first number of antennas, but does not belong to the antenna in the second number of antennas. Optionally, the target antenna may be one antenna or multiple antennas. Therefore, when the first terminal device should originally use the first number of antennas to send the SRS, the SRS can only send the SRS through the second number of antennas, where the first number is greater than the second number.

可理解，在第一网络设备和第二网络设备不同的情况下，具体的，在第一网络设备和第二网络设备属于不同的运营商的情况下，该第一网络设备和该第二网络设备之间的时间可能不同步。如第一网络设备和第二网络设备的帧边界、子帧边界、时隙边界、符号边界等等不对齐的情况下，第二时间区间可以为根据第一网络设备和第二网络设备之间的时间差，进行补偿后得到的时间区间。以及第一时间区间也可以为根据第一网络设备和第二网络设备之间的时间差，进行补偿后得到的时间区间。Understandably, in a case where the first network device and the second network device are different, specifically, in a case where the first network device and the second network device belong to different operators, the first network device and the second network The time between the devices may not be synchronized. For example, if the frame boundaries, subframe boundaries, slot boundaries, symbol boundaries, and so on of the first network device and the second network device are not aligned, the second time interval may be between the first network device and the second network device. Time difference, the time interval obtained after compensation. And the first time interval may also be a time interval obtained after compensation according to a time difference between the first network device and the second network device.

可理解，在第二终端设备处于on周期时，由于第二终端设备需要监听寻呼消息等等，因此相对来说，优先级较高，由此，第二终端设备可以使用天线。It can be understood that when the second terminal device is in the on cycle, because the second terminal device needs to listen to a paging message, etc., it has a relatively high priority, and thus the second terminal device can use an antenna.

具体的，该第一终端设备可以显式的方式在SRS指示信息中包括第一时间区间和第二时间区间，或者，该第一终端设备也可以隐式的方式来指示第一时间区间和第二时间区间。举例来说，该SRS指示信息中可包括第一时间区间和第二时间区间的时间和，以及第一时间区间，或者，该SRS指示信息中还可包括第一时间区间和第二时间区间的时间和，以及第二时间区间。至于具体采用何种的方式来指示第一时间区间和第二时间区间，本申请实施例不作唯一性限定。Specifically, the first terminal device may include the first time interval and the second time interval in the SRS indication information in an explicit manner, or the first terminal device may also indicate the first time interval and the first time interval in an implicit manner. Two time intervals. For example, the SRS indication information may include the time sum of the first time interval and the second time interval, and the first time interval, or the SRS indication information may further include the first time interval and the second time interval. Time sum, and second time interval. As for the specific method used to indicate the first time interval and the second time interval, the embodiment of the present application does not limit it uniquely.

本申请实施例中，第一终端设备和第一网络设备可以预先设置或预先协商第二终端设备所能使用的天线，从而使得第一终端设备向第一网络设备指示第一时间区间和第二时间区间，第一网络设备便可得知第一终端设备以及第二终端设备使用天线的情况。In the embodiment of the present application, the first terminal device and the first network device may pre-set or pre-negotiate antennas that can be used by the second terminal device, so that the first terminal device indicates the first time interval and the second network device to the first network device. In the time interval, the first network device can learn the use of the antenna by the first terminal device and the second terminal device.

可选的，本申请实施例中，SRS指示信息还可用于指示在第一时间区间内，使用第一数量的天线发送SRS，以及在第二时间区间内，使用第二数量的天线发送SRS。Optionally, in the embodiment of the present application, the SRS indication information may also be used to indicate that the SRS is transmitted using the first number of antennas in the first time interval, and the SRS is transmitted using the second number of antennas in the second time interval.

也就是说，SRS指示信息中还可包括第一终端设备使用的天线状态。That is, the SRS indication information may further include an antenna state used by the first terminal device.

可理解，本申请实施例中，也可将第一终端设备在第一时间区间内，使用第一数量的天线发送SRS划分为该第一终端设备的正常能力，而将在第二时间区间内，使用第二数量的天线发送SRS划分为该第一终端设备的回退(fallback)能力。从而在第一终端设备向第一网络设备发送SRS指示信息时，该SRS指示信息中包括该正常能力和回退能力。It can be understood that, in the embodiment of the present application, the first terminal device may also be used to transmit SRS using the first number of antennas in the first time interval to be divided into the normal capabilities of the first terminal device, and will be within the second time interval. , Sending the SRS using the second number of antennas is divided into a fallback capability of the first terminal device. Therefore, when the first terminal device sends the SRS indication information to the first network device, the SRS indication information includes the normal capability and the fallback capability.

具体的，该第一终端设备还可通过无线资源控制(radio resource control，RRC)信令向第一网络设备发送SRS指示信息。Specifically, the first terminal device may also send SRS indication information to the first network device through radio resource control (radio resource control (RRC) signaling).

为更形象的描述该SRS指示信息，以下以具体的例子为来说明。In order to describe the SRS indication information more vividly, a specific example is used as an illustration below.

如图9a所示，图9a是本申请实施例提供的一种SRS指示信息的内容示意图，图中sf40、sf64、sf80、sf128、sf160和sf256可用于表示第一时间区间和第二时间区间的时间和，如可表示该时间和为40ms、64ms…256ms等等。图中sf20、sf30、sf40、sf60、sf80和sf100可表示第一时间区间或第二时间区间，如可表示该第一时间区间或第二时间区间为20ms等等。以及0…255可表示偏移量。如以时间和为40ms，第一时间区间为20ms为例，如偏移量为0，则表示在40ms的时间区间内，前20ms为第一时间区间。又如偏移量为10，则表示在40ms的时间区间内，从第10ms至30ms的时间区间为第一时间区间。As shown in FIG. 9a, FIG. 9a is a schematic diagram of content of SRS indication information provided by an embodiment of the present application. In the figure, sf40, sf64, sf80, sf128, sf160 and sf256 can be used to represent Time sum, for example, the time sum can be expressed as 40ms, 64ms ... 256ms and so on. In the figure, sf20, sf30, sf40, sf60, sf80, and sf100 may represent a first time interval or a second time interval. For example, the first time interval or the second time interval may be 20 ms. And 0 ... 255 can represent the offset. For example, if the time sum is 40ms and the first time interval is 20ms, for example, if the offset is 0, it means that within the 40ms time interval, the first 20ms is the first time interval. For another example, the offset is 10, which means that within the time interval of 40ms, the time interval from the 10th to 30ms is the first time interval.

可理解，sf40、sf20等等中的数字还可表示为子帧、帧、时隙或符合的数量等，本申请实施例不作限定。It can be understood that the numbers in sf40, sf20, etc. can also be expressed as subframes, frames, time slots, or the number of matches, which are not limited in the embodiments of the present application.

如图9b所示，图9b是本申请实施例提供的另一种SRS指示信息的内容示意图，图中 firstcapability可表示正常能力，或者，也可称为第一能力(即表示正常能力)。图中secondcapability可表示回退能力，或者，也可称为第二能力。通过向第一网络设备指示第一时间区间、第二时间区间、正常能力和回退能力，从而使得第一网络设备得知第一终端设备以及第二终端设备使用天线的情况。As shown in FIG. 9b, FIG. 9b is a schematic diagram of content of another SRS indication information provided by an embodiment of the present application. In the figure, firstcapability may indicate normal capability, or may be referred to as first capability (that is, normal capability). The secondcapability in the figure may represent a rollback capability, or may be referred to as a second capability. The first network device is instructed to the first time interval, the second time interval, the normal capability, and the fallback capability, so that the first network device learns the use of the antenna by the first terminal device and the second terminal device.

如图9c所示，图9c是本申请实施例提供的一种帧边界不对齐的场景示意图，图中第二终端设备(副卡)的on周期所对应的帧可能是第5帧至第9帧，而对应于第一终端设备(主卡)的帧边界为第1帧至第5帧。因此，在SRS指示信息中的第一时间区间和第二时间区间以帧为单位来上报的情况下，第一终端设备向第一网络设备发送的SRS指示信息中的第二时间区间可为“从第1帧至第5帧，使用第二数量的天线发送SRS”。也就是说，第一终端设备不能直接使用“从第5帧至第9帧，使用第二数量的天线发送SRS”。As shown in FIG. 9c, FIG. 9c is a schematic diagram of a scenario where frame boundaries are not aligned according to an embodiment of the present application. The frame corresponding to the on period of the second terminal device (sub card) in the figure may be the fifth frame to the ninth frame. Frame, and the frame boundary corresponding to the first terminal device (master card) is the first frame to the fifth frame. Therefore, when the first time interval and the second time interval in the SRS indication information are reported in frame units, the second time interval in the SRS indication information sent by the first terminal device to the first network device may be " From the first frame to the fifth frame, the SRS is transmitted using the second number of antennas ". In other words, the first terminal device cannot directly use "from the fifth frame to the ninth frame, send the SRS using the second number of antennas".

可理解，以上仅为一种示例，不应理解为对本申请实施例的限定。It can be understood that the above is only an example, and should not be construed as limiting the embodiments of the present application.

可理解，第一终端设备向第一网络设备发送SRS指示信息之后，在第一网络设备无需向第一终端设备发送确认信息的情况下，第一终端设备便可直接执行步骤802。然而，在第一终端设备需要得到第一网络设备的认可，该第一终端设备才可执行步骤802的情况下，可参考以下实施例。It can be understood that after the first terminal device sends the SRS instruction information to the first network device, the first terminal device can directly perform step 802 without the first network device having to send confirmation information to the first terminal device. However, in the case that the first terminal device needs to be approved by the first network device before the first terminal device can perform step 802, reference may be made to the following embodiment.

也就是说，在步骤801之后，以及步骤802之前，本申请实施例所提供的通信方法还可包括：That is, after step 801 and before step 802, the communication method provided in the embodiment of the present application may further include:

811、第一网络设备向第一终端设备发送确认信息，该第一终端设备接收来自该第一网络设备的确认信息。811. The first network device sends confirmation information to the first terminal device, and the first terminal device receives the confirmation information from the first network device.

具体的，该确认信息可包括以下三种方式：Specifically, the confirmation information may include the following three methods:

方式一、method one,

该确认信息可用于指示确认SRS指示信息，也就是说，该确认信息可用于明确指示第一网络设备已确认该SRS指示信息。The confirmation information may be used to indicate confirmation of the SRS indication information, that is, the confirmation information may be used to explicitly indicate that the first network device has confirmed the SRS indication information.

方式二、Way two,

该确认信息可用于指示第一时间区间和第二时间区间。也就是说，该确认信息中可包括第一时间区间和第二时间区间，或者，该确认信息中还可包括第一时间区间和第二时间区间的时间和，以及第一时间区间，或者，该确认信息中还可包括第一时间区间和第二时间区间的时间和，以及第二时间区间。即该确认信息可用于隐式指示第一网络设备已确认该SRS指示信息。The confirmation information may be used to indicate the first time interval and the second time interval. That is, the confirmation information may include the first time interval and the second time interval, or the confirmation information may further include the time sum of the first time interval and the second time interval, and the first time interval, or, The confirmation information may further include the time sum of the first time interval and the second time interval, and the second time interval. That is, the confirmation information can be used to implicitly indicate that the first network device has confirmed the SRS indication information.

方式三、Way three,

该确认信息可用于指示在第一时间区间内，使用第一数量的天线发送SRS，在第二时间区间内，使用第二数量的天线发送SRS。也就是说，该确认信息中还可包括正常能力和回退能力。即该确认信息可用于隐式指示第一网络设备已确认该SRS指示信息。The confirmation information may be used to indicate that the SRS is transmitted using the first number of antennas in the first time interval, and the SRS is transmitted using the second number of antennas in the second time interval. That is, the confirmation information may also include normal capabilities and fallback capabilities. That is, the confirmation information can be used to implicitly indicate that the first network device has confirmed the SRS indication information.

可理解，以上仅为确认信息的三种方式，以上所示的三种方式不应理解为对本申请实施例的限定。It can be understood that the above are only three ways of confirming the information, and the three ways shown above should not be understood as limiting the embodiments of the present application.

本申请实施例中，为进一步提高第一终端设备与第一网络设备交互的效率，该第一终端设备可在接收到第一网络设备发送的确认信息之后，在第一时间区间，使用第一数量的天线发送SRS，以及在第二时间区间，使用第二数量的天线发送SRS，从而还可使得第一网络设备准确确定如何进行信道估计，进而进一步提高第一网络设备进行信道估计的准确度。In the embodiment of the present application, in order to further improve the efficiency of interaction between the first terminal device and the first network device, the first terminal device may use the first time interval in the first time interval after receiving the confirmation information sent by the first network device. The number of antennas to send the SRS, and the second number of antennas to send the SRS in the second time interval, so that the first network device can accurately determine how to perform channel estimation, thereby further improving the accuracy of the channel estimation by the first network device .

可理解，本申请实施例中所描述的第一数量的天线和第二数量的天线既可通过物理上的天线来实现，也可通过逻辑上的天线端口来实现。举例来说，该SRS指示信息还可用于指示在第一时间区间内，使用第四数量的天线端口来发送SRS，以及在第二时间区间内，使用第五数量的天线端口来发送SRS，该第四数量大于该第五数量。It can be understood that the first number of antennas and the second number of antennas described in the embodiments of the present application can be implemented through physical antennas or through logical antenna ports. For example, the SRS indication information may also be used to indicate that a fourth number of antenna ports are used to send SRS in the first time interval, and a second number of antenna ports are used to send SRS in the second time interval. The fourth number is greater than the fifth number.

具体的，每一个射频链路和天线的组合，可以代表一个信号的通路。当两个通路的信道特性可以相互分辨的情况下，就可以在逻辑上分为两个不同的天线端口。以及在硬件实现中，不同的天线之间的间隔一般大于0.5倍的电磁波波长，就可使得两个天线可以分辨。因此一般情况下，一个射频链路和天线的组合就可以认为对应一个天线端口。可理解，以上是关于天线端口的说明，在具体实现中，可能还有其他描述，因此，本申请实施例对于该天线端口具体是如何限定的不作限定。Specifically, each RF link and antenna combination can represent a signal path. When the channel characteristics of the two paths can be distinguished from each other, it can be logically divided into two different antenna ports. And in hardware implementation, the interval between different antennas is generally greater than 0.5 times the electromagnetic wave wavelength, so that the two antennas can be distinguished. Therefore, in general, a combination of an RF link and an antenna can be considered to correspond to an antenna port. It can be understood that the above is the description of the antenna port. In the specific implementation, there may be other descriptions. Therefore, the embodiment of the present application does not limit how the antenna port is specifically limited.

802、第一终端设备在第一时间区间内，使用第一数量的天线发送SRS，第一终端设备在第二时间区间内，使用第二数量的天线发送SRS；以及第一网络设备接收第一终端设备在第一时间区间内，使用第一数量的天线发送的SRS，第一网络设备接收第一终端设备在第二时间区间内，使用第二数量的天线发送的SRS。802. The first terminal device uses a first number of antennas to send SRS in a first time interval, and the first terminal device uses a second number of antennas to send SRS in a second time interval; and the first network device receives the first The terminal device uses the SRS sent by the first number of antennas in the first time interval, and the first network device receives the SRS sent by the first terminal device using the second number of antennas in the second time interval.

803、第一网络设备根据SRS指示信息进行信道估计。803. The first network device performs channel estimation according to the SRS indication information.

本申请实施例中，假设第一网络设备配置第一终端设备使用第三数量的天线发送SRS，其中，该第三数量可以与第一数量相同，也可以与第一数量不同，本申请实施例不作限定。在第一网络设备配置之后，第一终端设备向第一网络设备发送了SRS指示信息，然后第一终端设备便可执行步骤802，这时，第一网络设备可以根据第一终端设备最新的使用天线的状态来进行信道估计，提高了信道估计的准确性，避免了第一网络设备依然根据原先的配置来进行信道估计。In the embodiment of the present application, it is assumed that the first network device configures the first terminal device to send a SRS using a third number of antennas, where the third number may be the same as the first number or different from the first number. Not limited. After the first network device is configured, the first terminal device sends the SRS indication information to the first network device, and then the first terminal device can perform step 802. At this time, the first network device can perform the latest use according to the first terminal device. The state of the antenna to perform channel estimation improves the accuracy of the channel estimation and prevents the first network device from still performing channel estimation according to the original configuration.

804、第一网络设备确定上行调度信息。804. The first network device determines uplink scheduling information.

具体的，该上行调度信息中至少可包括端口号以及预编码矩阵等等，本申请实施例对于该上行调度信息中具体所包含的内容不作限定。Specifically, the uplink scheduling information may include at least a port number, a precoding matrix, and the like. The embodiment of the present application does not limit the specific content included in the uplink scheduling information.

805、第一网络设备向第一终端设备发送上行调度信息，该第一终端设备接收来自该第一网络设备的上行调度信息。805. The first network device sends uplink scheduling information to the first terminal device, and the first terminal device receives uplink scheduling information from the first network device.

806、第一终端设备根据上行调度信息，向第一网络设备发送上行数据。806. The first terminal device sends uplink data to the first network device according to the uplink scheduling information.

实施本申请实施例，可有效提高第一网络设备信道估计的准确性。Implementation of the embodiments of the present application can effectively improve the accuracy of channel estimation of the first network device.

可理解，对于图8所示的通信方法还可应用于TDD***中，即根据上行信道和下行信道的互易性，第一网络设备在接收到第一终端设备发送的SRS之后，可利用信道互易性进行下行信道估计。具体的，进行信道估计的方法可如图4b所示，这里不再一一详述。也就是说，第一网络设备接收到来自第一终端设备的SRS指示信息，以及SRS之后，该第一网络设备不仅可进行上行信道估计，还可进行下行信道估计，从而确定下行调度信息，进而将该下行调度信息发送给第一终端设备后，便可向该第一终端设备发送下行数据。It can be understood that the communication method shown in FIG. 8 can also be applied to a TDD system, that is, according to the reciprocity of the uplink channel and the downlink channel, the first network device can use the channel after receiving the SRS sent by the first terminal device. Reciprocity performs downlink channel estimation. Specifically, a method for performing channel estimation may be shown in FIG. 4b, which is not described in detail here. That is, after the first network device receives the SRS indication information from the first terminal device, and after the SRS, the first network device can not only perform uplink channel estimation but also downlink channel estimation, thereby determining downlink scheduling information, and further After sending the downlink scheduling information to the first terminal device, downlink data can be sent to the first terminal device.

可选的，在第一终端设备接收到来自第一网络设备的确认信息的情况下，该第一终端设备便可执行步骤802。然而，第一终端设备也可能未接收到该确认信息，一种原因可能为该第一网络设备的确未接收到SRS指示信息，另一种原因可能为该第一网络设备不想确认该SRS指示信息。因此在第一终端设备向第一网络设备发送SRS指示信息之后，上述方法还包括以下两种场景：Optionally, when the first terminal device receives the confirmation information from the first network device, the first terminal device may perform step 802. However, the first terminal device may also not receive the confirmation information. One reason may be that the first network device does not receive the SRS indication information, and another reason may be that the first network device does not want to confirm the SRS indication information. . Therefore, after the first terminal device sends the SRS indication information to the first network device, the foregoing method further includes the following two scenarios:

场景一、scene one,

在第一终端设备未接收到来自第一网络设备的确认信息的情况下，该第一终端设备重新向该第一网络设备发送SRS指示信息。When the first terminal device does not receive the confirmation information from the first network device, the first terminal device re-sends the SRS instruction information to the first network device.

对于该场景，该第一终端设备可以重新向第一网络设备发送SRS指示信息，以避免第一网络设备未接收到该SRS指示信息的情况。For this scenario, the first terminal device may re-send the SRS indication information to the first network device to avoid a situation where the first network device does not receive the SRS indication information.

场景二、Scene two,

在第一终端设备未接收到来自第一网络设备的确认信息的情况下，该第一终端设备使用第三数量的天线发送SRS。In the case that the first terminal device does not receive the confirmation information from the first network device, the first terminal device uses a third number of antennas to send the SRS.

对于该场景，该第一终端设备可以使用原先的配置使用天线，如使用第三数量的天线发送SRS。For this scenario, the first terminal device may use an antenna using the original configuration, such as sending a SRS using a third number of antennas.

本申请实施例中，在第一终端设备未接收到确认信息的情况下，很可能是由于第一网络设备未接收到SRS指示信息，因此，第一终端设备可重新发送该SRS指示信息。或者，在第一终端设备未接收到确认信息的情况下，很可能是由于第一网络设备对该SRS指示信息未进行确认，因此该第一终端设备可使用原来的配置如使用第三数量的天线发送SRS。由此，可提高第一终端设备与第一网络设备的交互效率。In the embodiment of the present application, if the first terminal device does not receive the confirmation information, it is likely that the first network device does not receive the SRS instruction information, and therefore the first terminal device may resend the SRS instruction information. Or, in the case that the first terminal device does not receive the confirmation information, it is likely that the first network device has not confirmed the SRS indication information, so the first terminal device may use the original configuration, such as a third quantity. The antenna sends SRS. Therefore, the interaction efficiency between the first terminal device and the first network device can be improved.

可选的，在第一终端设备向第一网络设备发送SRS指示信息之后，第二终端设备可能会出现紧急情况或突出状态，而导致该第二终端设备不需要使用目标天线了，因此，在第一终端设备向第一网络设备发送SRS指示信息之后，上述方法还包括：Optionally, after the first terminal device sends the SRS indication information to the first network device, the second terminal device may be in an emergency or prominent state, resulting in that the second terminal device does not need to use the target antenna. Therefore, in After the first terminal device sends the SRS indication information to the first network device, the method further includes:

在第二时间区间内，第二终端设备不使用目标天线的情况下，第一终端设备向第一网络设备发送取消指令，该取消指令可用于指示使用第三数量的天线发送SRS。In the second time interval, when the second terminal device does not use the target antenna, the first terminal device sends a cancellation instruction to the first network device, and the cancellation instruction may be used to instruct the third number of antennas to send the SRS.

本申请实施例中，第一终端设备向第一网络设备发送取消指令可表示第二终端设备不需要使用目标天线了，也可表示该第一终端设备可以在第二时间区间内使用目标天线来发送SRS了。也就是说，该取消指令可用于指示第一网络设备，该第一终端设备可以使用原来的配置发送SRS了。In the embodiment of the present application, the first terminal device sending the cancellation instruction to the first network device may indicate that the second terminal device does not need to use the target antenna, and may also indicate that the first terminal device may use the target antenna in the second time interval. SRS sent. That is, the cancellation instruction may be used to instruct the first network device, and the first terminal device may send the SRS using the original configuration.

可理解，本申请实施例所提供的方法可在步骤801之后，或者，也可在步骤802之后等等，本申请实施例不作限定。It can be understood that the method provided in the embodiment of the present application may be after step 801, or after step 802, and so on, and the embodiment of the present application is not limited.

可理解，本申请实施例中所提供的通信方法中，也可以将通过不同的天线发送的SRS称为不同的SRS，如第一数量的天线中包括第一天线和第二天线，则通过第一天线发送的SRS可以称为第一SRS，以及通过第二天线发送的SRS称为第二SRS。也就是说，如将通过第一数量的天线发送的SRS称为第一数量的SRS，将通过第二数量的天线发送的SRS称为第二数量的SRS，则可以该第一数量的SRS以及该第二数量的SRS统称为SRS等等，本申请实施例对于通过不同天线发送的SRS是否相同不作限定。因此，不应将图8所示的通信方法中的SRS理解为对本申请实施例的限定。It can be understood that, in the communication method provided in the embodiment of the present application, SRSs transmitted through different antennas may also be referred to as different SRSs. For example, if the first number of antennas includes the first antenna and the second antenna, the The SRS transmitted by one antenna may be referred to as a first SRS, and the SRS transmitted through a second antenna is referred to as a second SRS. That is, if the SRS transmitted through the first number of antennas is referred to as the first number of SRSs, and the SRS transmitted through the second number of antennas is referred to as the second number of SRSs, the first number of SRSs and The second number of SRSs are collectively referred to as SRS and so on. The embodiment of the present application does not limit whether the SRSs sent through different antennas are the same. Therefore, the SRS in the communication method shown in FIG. 8 should not be understood as limiting the embodiments of the present application.

上述详细描述了本申请实施例的方法，下面提供了本申请实施例的装置。The foregoing describes the method in the embodiment of the present application in detail, and the apparatus in the embodiment of the present application is provided below.

可理解，图10和图11所示的终端设备的具体实现方式，可参考图8所示的通信方法的描述，这里不再一一详述。It can be understood that, for specific implementation manners of the terminal devices shown in FIG. 10 and FIG. 11, reference may be made to the description of the communication method shown in FIG. 8, which will not be detailed one by one here.

图12为本申请实施例提供的一种终端设备1200的结构示意图。该终端设备可执行如图8所示出的方法中的终端设备的操作，或者该终端设备也可以执行图10和图11所示的终端设备的操作。FIG. 12 is a schematic structural diagram of a terminal device 1200 according to an embodiment of the present application. The terminal device may perform operations of the terminal device in the method shown in FIG. 8, or the terminal device may also perform operations of the terminal device shown in FIG. 10 and FIG. 11.

为了便于说明，图12仅示出了终端设备的主要部件。如图12所示，终端设备1200包括处理器、存储器、射频链路、天线以及输入输出装置。处理器主要用于对通信协议以及通信数据进行处理，以及对整个终端设备进行控制，执行软件程序，处理软件程序的数据，例如用于支持终端设备执行图8所描述的流程。存储器主要用于存储软件程序和数据。射频链路主要用于基带信号与射频信号的转换以及对射频信号的处理。天线主要用于收发电磁波形式的射频信号。终端设备1200还可以包括输入输出装置，例如触摸屏、显示屏，键盘等主要用于接收用户输入的数据以及对用户输出数据。需要说明的是，有些种类的终端设备可以不具有输入输出装置。For convenience of explanation, FIG. 12 shows only the main components of the terminal device. As shown in FIG. 12, the terminal device 1200 includes a processor, a memory, a radio frequency link, an antenna, and an input / output device. The processor is mainly used to process the communication protocol and communication data, and control the entire terminal device, execute a software program, and process the data of the software program, for example, to support the terminal device to execute the process described in FIG. 8. The memory is mainly used for storing software programs and data.

When data is sent to the terminal device, the RF link receives the RF signal through the antenna, converts the RF signal into a baseband signal, and outputs the baseband signal to the processor. The processor converts the baseband signal into data and processes the data. .

可理解，图12所示的射频链路中可至少包括两个射频链路，如可包括第一射频链路和第二射频链路。也就是说，该射频链路可包括图7所示的示意图中的射频链路。It may be understood that the radio frequency link shown in FIG. 12 may include at least two radio frequency links, for example, may include a first radio frequency link and a second radio frequency link. That is, the radio frequency link may include the radio frequency link in the schematic diagram shown in FIG. 7.
