技术领域Technical field

本发明涉及导频技术领域，特别涉及一种终端确定保持锁相环开启的方法及装置。The present invention relates to the field of pilot technologies, and in particular, to a method and apparatus for determining that a phase locked loop is maintained by a terminal.

背景技术Background technique

随着移动通信业务需求的发展变化，国际电信联盟(International elecommunication Union，ITU)等多个组织对未来移动通信***都定义了更高的用户面延时性能要求。缩短用户延时性能的主要方法之一是降低传输时间间隔(Transmission Time Interval，TTI)的长度，因此提出了短TTI(sTTI)传输方案。在该传输方案中一个子帧可以被划分为多个sTTI，例如当sTTI的长度为2个符号或3个符号时，可以按照如图1A所示的方式将一个子帧划分为6个sTTI，用sTTI index 0-5表示，其中第一个sTTI和最后一个sTTI包含3个符号，其余sTTI都包含2个符号，一个子帧共包含符号0-13共14个符号，用Synbol index0-13表示，并且如图1A所示的一个时隙边界(Slot boundary)，表示一个子帧包含两个Slot(时隙)。With the development of mobile communication services, organizations such as the International elecommunication Union (ITU) have defined higher user plane delay performance requirements for future mobile communication systems. One of the main methods to shorten the user's delay performance is to reduce the length of the Transmission Time Interval (TTI). Therefore, a short TTI (sTTI) transmission scheme is proposed. In the transmission scheme, one subframe may be divided into multiple sTTIs. For example, when the length of the sTTI is 2 symbols or 3 symbols, one subframe may be divided into 6 sTTIs as shown in FIG. 1A. It is represented by sTTI index 0-5, where the first sTTI and the last sTTI contain 3 symbols, and the remaining sTTIs contain 2 symbols. One subframe contains a total of 14 symbols of 0-13, represented by Synbol index0-13. And a slot boundary as shown in FIG. 1A, indicating that one subframe contains two slots (slots).

在sTTI上行传输时，为了降低解调参考符号(DeModulation Reference Signal，DMRS)开销，用户设备(User equipment，UE，也称终端)可以支持多个sTTI在一个sTTI中的同一个符号上通过码分复用(Code Division Multiplexing，CDM)和/或频分复用(Frequency Division Multiplexing，FDM)传输DMRS。一个UE在一个sTTIx中传输的数据所对应的DMRS可能在与该sTTIx不相邻的sTTIy中的一个符号上传输，如果该UE在sTTIx和sTTIy之间的sTTI中没有被调度即不存在传输，UE为了省电，会在sTTIx和sTTIy之间的sTTI中进入不连续发送(Discontinuous Transmission，DTX)状态，此时UE将关闭射频器件，这将会导致sTTIx和sTTIy的相位不连续，从而导致sTTIy中传输的DMRS不能用于sTTIx中传输的数据的解调。关闭射频器件，主要是关闭射频器件中的锁相环(Phase Locked Loop，PLL)，当锁相环保持开启时，可以保证开启时间段内频率源的相位是连续的。In the sTTI uplink transmission, in order to reduce the DeModulation Reference Signal (DMRS) overhead, the user equipment (UE, also called the terminal) can support multiple sTTIs to pass the code on the same symbol in one sTTI. DMRS is transmitted by Code Division Multiplexing (CDM) and/or Frequency Division Multiplexing (FDM). A DMRS corresponding to data transmitted by one UE in one sTTIx may be transmitted on one symbol in sTTIy that is not adjacent to the sTTIx, and if the UE is not scheduled in the sTTI between sTTIx and sTTIy, there is no transmission. In order to save power, the UE enters a discontinuous transmission (DTX) state in the sTTI between sTTIx and sTTIy. At this time, the UE will turn off the radio device, which will cause the phases of sTTIx and sTTIy to be discontinuous, resulting in sTTIy. The DMRS transmitted in the middle cannot be used for demodulation of data transmitted in sTTIx. Turn off the RF device, mainly to turn off the Phase Locked Loop (PLL) in the RF device. When the phase-locked loop is kept open, the phase of the frequency source is guaranteed to be continuous during the turn-on period.

例如，如图1B所示，当UE1被调度在sTTI1和sTTI3中进行数据传输时，UE1在sTTI1和sTTI3中传输的数据所对应DMRS在sTTI1中的第一个符号上的每个资源块(Resource  Block，RB)中的第二个子载波(K _TC＝1)开始间隔一个子载波映射。此时，由于UE1在sTTI2中不存在传输，则为了节电，UE1会在sTTI2中进入DTX状态而关闭射频器件，在sTTI3中再次开启射频器件进行传输，则射频器件的开关过程将可能导致sTTI1和sTTI3中的相位不连续，从而导致在sTTI1中传输的DMRS不能用于sTTI3中的传输的数据的解调。 For example, as shown in FIG. 1B, when UE1 is scheduled to perform data transmission in sTTI1 and sTTI3, each resource block of the DMRS corresponding to the data transmitted by UE1 in sTTI1 and sTTI3 on the first symbol in sTTI1 (Resource) The second subcarrier (K _TC =1) in Block, RB) starts to be separated by one subcarrier mapping. At this time, since UE1 does not have transmission in sTTI2, UE1 will enter the DTX state in sTTI2 to turn off the RF device for power saving, and turn on the RF device again in sTTI3 for transmission. The switching process of the RF device may cause sTTI1. The phase in sTTI3 is not continuous, so that the DMRS transmitted in sTTI1 cannot be used for demodulation of the transmitted data in sTTI3.

又例如，UE2被调度仅在sTTI2中进行数据传输，UE2在sTTI2中的数据传输所对应的DMRS在sTTI1的第一个符号上的每个RB中的第一个子载波(K _TC＝0)开始间隔一个子载波映射。此时，由于UE2仅在sTTI1中的第一个符号上存在传输，在sTTI1中的其他符号上不存在传输，则为了节电，UE2会在sTTI1中的除了传输DMRS以外的符号进入DTX状态而关闭射频器件，在sTTI2中再次开启射频器件进行传输，则射频器件的开关过程将可能导致sTTI1和sTTI2中的相位不连续，从而导致在sTTI1中传输的DMRS不能用于sTTI2中传输的数据的解调。 For another example, UE2 is scheduled to perform data transmission only in sTTI2, and the first subcarrier in each RB of the DMRS corresponding to the data transmission of UE2 in sTTI2 on the first symbol of sTTI1 (K _TC =0) Start with a subcarrier mapping. At this time, since UE2 only has transmission on the first symbol in sTTI1, there is no transmission on other symbols in sTTI1, and in order to save power, UE2 enters DTX state in sTTI1 except for transmitting DMRS. Turn off the RF device and turn on the RF device for transmission again in sTTI2. The switching process of the RF device may cause the phase in sTTI1 and sTTI2 to be discontinuous. As a result, the DMRS transmitted in sTTI1 cannot be used for the solution of data transmitted in sTTI2. Tune.

综上可知，数据传输与其对应的DMRS的相位不连续，从而导致DMRS不能用于数据解调。但是如何保证数据传输与其对应的DMRS的相位连续性，从而保证DMRS可用于数据解调，目前还没有相关解决办法。In summary, the phase of the data transmission and its corresponding DMRS are not continuous, resulting in DMRS not being used for data demodulation. However, how to ensure the phase continuity of the data transmission and its corresponding DMRS, so as to ensure that the DMRS can be used for data demodulation, there is no relevant solution at present.

The method includes: determining, by the UE, whether to keep the phase-locked loop open according to a pre-agreed method or a configuration or transmission condition of the configuration signaling.

为了保证数据传输与其对应的DMRS的相位连续，以便DMRS可以用于数据解调，在本发明实施例中UE在确定是否保持锁相环开启时，可以根据预先约定的方法来确定，也可以根据配置信令的配置来确定，还可以根据传输情况来确定。In order to ensure that the data transmission is consistent with the phase of the corresponding DMRS, so that the DMRS can be used for data demodulation, in the embodiment of the present invention, when determining whether to keep the phase-locked loop open, the UE may determine according to a pre-agreed method, or may The configuration of the configuration signaling is determined, and can also be determined according to the transmission situation.

下面通过不同的实施例，对本发明中的终端确定是否保持锁相环开启的实施过程进行详细说明。The implementation process of determining whether to keep the phase locked loop open by the terminal in the present invention will be described in detail below through different embodiments.

实施例1：Example 1:

在本发明实施例中UE根据预先约定的方法，确定是否保持锁相环开启，具体的，所 述UE根据预先约定的方法，确定是否保持锁相环开启包括：UE确定一直保持锁相环开启。In the embodiment of the present invention, the UE determines whether to keep the phase-locked loop open according to a pre-agreed method. Specifically, the UE determines whether to keep the phase-locked loop open according to a pre-agreed method, and includes: determining, by the UE, that the phase-locked loop is kept open. .

在本发明实施例中UE无需确定在每个时间单元中是否存在传输，一直保持锁相环开启(PLL on)，这样可以维持所有符号的相位连续性，且不需要额外信令通知。In the embodiment of the present invention, the UE does not need to determine whether there is a transmission in each time unit, and keeps the phase locked loop on (PLL on), so that the phase continuity of all symbols can be maintained, and no additional signaling is needed.

实施例2：Example 2:

在本发明实施例中UE还可以根据传输情况，确定是否保持锁相环开启，具体的，所述UE根据传输情况，确定是否保持锁相环开启包括：如果UE确定时间单元k1中包含用于传输DMRS的符号，所述UE确定是否保持锁相环开启包括至少如下方法之一：In the embodiment of the present invention, the UE may further determine whether to keep the phase-locked loop open according to the transmission situation. Specifically, the determining, by the UE, whether to keep the phase-locked loop open according to the transmission situation includes: if the UE determines that the time unit k1 is included for Transmitting the symbol of the DMRS, the UE determining whether to keep the phase locked loop open includes at least one of the following methods:

UE确定在所述时间单元k1所在的时隙或子帧中保持锁相环开启；The UE determines to keep the phase locked loop open in the time slot or subframe in which the time unit k1 is located;

UE确定从所述时间单元k1的结束位置到所述时间单元k1所在的时隙或子帧的结束位置保持锁相环开启；Determining, by the UE, that the phase locked loop is turned on from the end position of the time unit k1 to the end position of the time slot or subframe in which the time unit k1 is located;

UE确定从所述时间单元k1的开始位置到所述时间单元k1所在的时隙或子帧的结束位置保持锁相环开启；The UE determines to keep the phase locked loop from being opened from the start position of the time unit k1 to the end position of the time slot or subframe where the time unit k1 is located;

UE启动定时器，在预设的计时时长内一直保持锁相环开启；The UE starts the timer and keeps the phase locked loop open for a preset time period;

UE启动定时器，在计时过程中，确定所述时间单元k1之后的时间单元k3中包含用于传输DMRS的符号时，结束计时，在结束计时之前一直保持锁相环开启。The UE starts a timer. When it is determined that the time unit k3 after the time unit k1 includes a symbol for transmitting the DMRS, the timing is ended, and the phase locked loop is kept open until the end of the timing.

在本发明实施例中UE可以根据传输情况，确定是否保持锁相环开启，该实施例中当UE确定时间单元k1中包含用于传输DMRS的符号时，则可以采用上述方法之一确定是否保持锁相环开启。该时间单元k1中可以仅传输DMRS，也可以同时传输DMRS和数据。当确定是否保持锁相环开启时，具体的还可以确定锁相环开启的时刻，以及关闭的时刻，而在确定锁相环开启的时刻和关闭的时刻时，可以根据时间单元k1所在的时隙或子帧来确定，也可以根据定时时长为预设的计时时长的定时器来确定。In the embodiment of the present invention, the UE may determine whether to keep the phase-locked loop open according to the transmission situation. When the UE determines that the time unit k1 includes the symbol for transmitting the DMRS, the method may determine whether to maintain by using one of the foregoing methods. The phase locked loop is turned on. In the time unit k1, only the DMRS may be transmitted, or the DMRS and the data may be simultaneously transmitted. When it is determined whether to keep the phase locked loop open, the time at which the phase locked loop is turned on and the time of turning off can be specifically determined, and when determining the time when the phase locked loop is turned on and the moment of turning off, according to the time when the time unit k1 is located The slot or subframe is determined, and may also be determined according to a timer whose timing duration is a preset timing duration.

其中，预设的计时时长为第一数量个符号(symbol)，或第二数量个时隙(slot)，或第三数量个微时隙(mini-slot)，或第四数量个子帧(subframe)，或第五数量个时间单元，第六数量个短传输时间间隔sTTI，其中所述第一数量、第二数量、第三数量、第四数量、第五数量和第六数量为不小于1的整数。The preset timing duration is a first number of symbols, or a second number of slots, or a third number of mini-slots, or a fourth number of subframes (subframes) a fifth number of time units, a sixth number of short transmission time intervals sTTI, wherein the first quantity, the second quantity, the third quantity, the fourth quantity, the fifth quantity, and the sixth quantity are not less than one The integer.

如图2A所示的终端传输数据和DMRS的示意图，如图2A所示，一个子帧包含2个slot，每个slot包含3个sTTI，该子帧的第一个和最后一个sTTI包含3个符号，其余sTTI各包含2个符号。UE1根据调度信令或者预定的数据导频结构确定在sTTI1和sTTI3中通过物理上行共享信道(Physical UplinkShared Channel，PUSCH)或物理下行共享信道(Physical Downlink Shared Channel，PDSCH)进行数据传输，sTTI1和sTTI3中的数据所对应的DMRS在sTTI1中的第一符号上传输。其中，sTTI2中可能存在其他UE的数据传 输，sTTI1中的第一个符号上空白的资源元素(Resource Element，RE)位置可以用来传输sTTI2中数据的DMRS。对于UE1而言，其DMRS和对应的数据在不同的sTTI中传输，中间间隔了1个sTTI2。为了保证DMRS和对应的数据相位连续性，在本发明实施例中UE1可采用如下方法之一确定是否保持锁相环开启：As shown in FIG. 2A, as shown in FIG. 2A, one subframe includes two slots, each slot includes three sTTIs, and the first and last sTTIs of the subframe include three. Symbol, the remaining sTTIs each contain 2 symbols. The UE1 determines, according to the scheduling signaling or the predetermined data pilot structure, the data transmission in the sTTI1 and the sTTI3 through the Physical Uplink Shared Channel (PUSCH) or the Physical Downlink Shared Channel (PDSCH), sTTI1 and sTTI3. The DMRS corresponding to the data in the data is transmitted on the first symbol in sTTI1. The data transmission of other UEs may exist in the sTTI2, and the location of the resource element (Resource Element, RE) on the first symbol in the sTTI1 may be used to transmit the DMRS of the data in the sTTI2. For UE1, its DMRS and corresponding data are transmitted in different sTTIs with an interval of 1 sTTI2. In order to ensure the DMRS and the corresponding data phase continuity, in the embodiment of the present invention, the UE1 may determine whether to keep the phase locked loop open by using one of the following methods:

方法1：UE1确定sTTI1中包含用于传输DMRS的符号，则UE1确定在sTTI1的结束位置保持锁相环开启，直到sTTI1所在的slot或子帧的结束位置。因为sTTI1本身存在传输，所以在sTTI1中锁相环开启。在该sTTI1所在的slot或子帧之后，UE1是否继续保持锁相环开启取决于后一个slot或子帧中的每个sTTI的调度和传输情况，具体判断方式与该sTTI1所在的slot或子帧类似。Method 1: UE1 determines that sTTI1 includes a symbol for transmitting a DMRS, and UE1 determines to keep the phase locked loop open at the end position of sTTI1 until the end of the slot or subframe in which sTTI1 is located. Since sTTI1 itself has a transmission, the phase-locked loop is turned on in sTTI1. After the slot or subframe in which the sTTI1 is located, whether UE1 continues to keep the phase locked loop on depends on the scheduling and transmission of each sTTI in the latter slot or subframe, and the specific judgment manner is the slot or subframe in which the sTTI1 is located. similar.

方法2：UE1确定sTTI1中包含用于传输DMRS的符号，则UE1确定在sTTI1的结束位置或开始位置启动定时器，在定时器的计时时长内，即在计时结束之前一直保持锁相环开启，如果在sTTI1的开始位置启动定时器，定时器的计时时长则包含sTTI1传输时间，如果在sTTI1的结束位置启动定时器，定时器的计时时长则不包含sTTI1传输时间。Method 2: UE1 determines that sTTI1 includes a symbol for transmitting DMRS, and UE1 determines to start a timer at an end position or a start position of sTTI1, and keeps the phase locked loop open for a period of time of the timer, that is, before the end of the timer. If the timer is started at the beginning of sTTI1, the timer duration includes the sTTI1 transmission time. If the timer is started at the end of sTTI1, the timer duration does not include the sTTI1 transmission time.

例如，计时时长为1个slot或3个sTTI长度，则如果UE1在sTTI1的开始位置启动定时器，在定时器的计时时长内一直保持锁相环开启，即在sTTI1所在slot的结束位置之前一直保持锁相环开启；如果UE1在sTTI1的结束位置启动定时器，则计时到下一个slot中的相应位置保持锁相环开启，该相应位置满足从sTTI1的结束位置到该位置长度为1个slot的计时时长。For example, if the timing is 1 slot or 3 sTTI lengths, if UE1 starts the timer at the beginning of sTTI1, the phase-locked loop is kept open for the duration of the timer, that is, until the end of the slot where sTTI1 is located. Keep the phase-locked loop open; if UE1 starts the timer at the end position of sTTI1, the corresponding position in the next slot is counted to keep the phase-locked loop open, and the corresponding position satisfies the end position from sTTI1 to the position of 1 slot. The timing of the time.

方法3：UE1确定sTTI1中包含用于传输DMRS的符号，则UE1确定在sTTI1的结束位置或开始位置启动定时器，计时时长为1个子帧或6个sTTI长度，UE1在计时过程中，确定sTTI4中包含DMRS，则在sTTI3的结束位置结束计时，在结束计时之前一直保持锁相环开启。结束计时之后，在sTTI4中以及以后的sTTI中是否还需要保持锁相环开启，可以按照上述sTTI1类似的方式进行判断。Method 3: UE1 determines that sTTI1 includes a symbol for transmitting DMRS, and UE1 determines to start a timer at an end position or a start position of sTTI1, and the timing duration is 1 subframe or 6 sTTI length, and UE1 determines sTTI4 during timing. The DMRS is included, and the timing ends at the end of sTTI3, and the phase locked loop is kept open until the end of the timing. After the end of the timer, whether the phase-locked loop needs to be turned on in sTTI4 and later sTTI can be judged in a similar manner to the above sTTI1.

如图2B所示的终端传输数据和DMRS的示意图，如图2B所示，一个子帧包含2个slot，每个slot包含3个sTTI，该子帧的第一个和最后一个sTTI包含3个符号，其余sTTI各包含2个符号。UE1根据调度信令或者预定的数据导频结构确定在sTTI3中通过PUSCH或PUCCH进行数据传输，sTTI3中的数据所对应的DMRS在sTTI1中的第一符号上传输，UE1在sTTI1中的第二和第三个符号上不存在传输，在sTTI2中也不存在传输，其中，sTTI1中的第二和第三个符号以及sTTI2中可能存在其他UE的数据传输，sTTI1中的第一个符号上空白的RE位置可以用来传输sTTI1和sTTI2中数据的DMRS。对于UE1而言，其DMRS和对应的数据在不同的sTTI中传输，中间间隔了1个sTTI2以及sTTI1中的两个符号，为 了保证DMRS和对应的数据相位连续性，在本发明实施例中UE1可采用如下方法之一确定是否保持锁相环开启：As shown in FIG. 2B, as shown in FIG. 2B, one subframe includes two slots, each slot includes three sTTIs, and the first and last sTTIs of the subframe include three. Symbol, the remaining sTTIs each contain 2 symbols. The UE1 determines, according to the scheduling signaling or the predetermined data pilot structure, data transmission through the PUSCH or the PUCCH in the sTTI3, and the DMRS corresponding to the data in the sTTI3 is transmitted on the first symbol in the sTTI1, and the second sum of the UE1 in the sTTI1 There is no transmission on the third symbol, and there is no transmission in sTTI2. The second and third symbols in sTTI1 and the data transmission of other UEs may exist in sTTI2, and the first symbol in sTTI1 is blank. The RE position can be used to transmit the DMRS of the data in sTTI1 and sTTI2. For the UE1, the DMRS and the corresponding data are transmitted in different sTTIs, and one sTTI2 and two symbols in the sTTI1 are separated in the middle. To ensure the DMRS and the corresponding data phase continuity, in the embodiment of the present invention, UE1 One of the following methods can be used to determine whether to keep the phase locked loop open:

方法1：UE1确定sTTI1中包含用于DMRS传输的符号，则UE1确定从sTTI1的结束位置或sTTI1中的用于传输DMRS的符号的结束位置，到sTTI1所在的slot或子帧的结束位置保持锁相环开启。在该sTTI1所在的slot或子帧之后，是否继续保持锁相环开启取决于后一个slot或子帧中的每个sTTI的调度和传输情况，具体判断方式与该sTTI1所在的slot或子帧类似。Method 1: UE1 determines that sTTI1 includes a symbol for DMRS transmission, and UE1 determines to keep the lock from the end position of sTTI1 or the end position of the symbol for transmitting DMRS in sTTI1, to the end position of slot or subframe where sTTI1 is located. The phase ring is turned on. After the slot or subframe where the sTTI1 is located, whether to keep the phase-locked loop open depends on the scheduling and transmission of each sTTI in the next slot or subframe, and the specific judgment manner is similar to the slot or subframe in which the sTTI1 is located. .

当UE1确定从sTTI1的结束位置开始保持锁相环开启时，时间单元可以是sTTI级别，因为sTTI1本身在一个符号上存在传输，则在sTTI1中UE1本身就保持锁相环开启。When UE1 determines to keep the phase locked loop open from the end position of sTTI1, the time unit may be the sTTI level. Since sTTI1 itself has transmission on one symbol, UE1 itself keeps the phase locked loop open in sTTI1.

当UE1确定从sTTI1中的用于传输DMRS的符号的结束位置开始保持锁相环开启时，时间单元可以是符号级别，因为sTTI1中仅在第一个符号存在传输，则UE1本身在第一个符号上必然保持锁相环开启。When UE1 determines to keep the phase locked loop open from the end position of the symbol for transmitting the DMRS in sTTI1, the time unit may be the symbol level, because there is only transmission in the first symbol in sTTI1, UE1 itself is in the first The symbol phase must keep the phase locked loop open.

方法2：UE1确定sTTI1中包含用于传输DMRS的符号，则UE1确定在sTTI1的结束位置，或在sTTI1的开始位置，或在sTTI1中的用于传输DMRS的符号的结束位置，或在sTTI1中的用于传输DMRS的符号的开始位置，启动定时器，在计时结束之前一直保持锁相环开启。Method 2: UE1 determines that sTTI1 includes a symbol for transmitting DMRS, and UE1 determines an end position at sTTI1, or a start position of sTTI1, or an end position of a symbol for transmitting DMRS in sTTI1, or in sTTI1 The start position of the symbol used to transmit the DMRS, the timer is started, and the phase locked loop is kept turned on until the end of the timer.

如果在sTTI1的开始位置启动定时器，sTTI1传输时间包含在定时器的计时时长内，如果在sTTI1的结束位置启动定时器，sTTI1传输时间则不包含在定时器的计时时长内，此时时间单元可以是sTTI级别，因为sTTI1本身在一个符号上存在传输，则在sTTI1中UE1本身就保持锁相环开启。If the timer is started at the beginning of sTTI1, the sTTI1 transmission time is included in the timer duration. If the timer is started at the end of sTTI1, the sTTI1 transmission time is not included in the timer duration. It can be sTTI level, because sTTI1 itself has transmission on one symbol, then UE1 itself keeps the phase-locked loop on in sTTI1.

如果在sTTI1中的用于传输DMRS的符号的开始位置启动定时器，sTTI1中的用于传输DMRS的符号的传输时间包含在定时器的计时时长内，如果在sTTI1中的用于传输DMRS的符号的结束位置启动定时器，sTTI1中的用于传输DMRS的符号的传输时间不包含在定时器的计时时长内，此时时间单元可以是符号级别，因为sTTI1中仅在第一个符号存在传输，则UE1本身在第一个符号上必然保持锁相环开启。If the start position of the symbol for transmitting the DMRS in sTTI1 starts the timer, the transmission time of the symbol for transmitting the DMRS in sTTI1 is included in the timing of the timer, if the symbol for transmitting the DMRS in sTTI1 The end position starts the timer. The transmission time of the symbol used to transmit the DMRS in sTTI1 is not included in the timer duration of the timer. In this case, the time unit can be at the symbol level, because only the first symbol exists in sTTI1. Then UE1 itself must keep the phase locked loop open on the first symbol.

例如，计时时长为1个slot或3个sTTI长度，则如果UE1在sTTI1的开始位置启动定时器，在定时器的计时时长内一直保持锁相环开启，则在sTTI1所在slot结束位置之前一直保持锁相环开启；如果UE1在sTTI1的结束位置启动定时器，则计时到下一个slot中的相应位置保持锁相环开启，该相应位置满足从sTTI1的结束位置到该位置长度为1个slot的计时时长。For example, if the timer duration is 1 slot or 3 sTTI lengths, if UE1 starts the timer at the start position of sTTI1, the phase-locked loop is kept open for the duration of the timer, and then remains until the slot end position of sTTI1 is maintained. The phase-locked loop is turned on; if the UE1 starts the timer at the end position of the sTTI1, the corresponding position in the next slot is counted to keep the phase-locked loop open, and the corresponding position satisfies the end position from the sTTI1 to the length of the slot. Timing time.

方法3：UE1确定sTTI1中包含用于传输DMRS的符号，则UE1确定在sTTI1的结束 位置或开始位置启动定时器，计时时长为1个子帧或6个sTTI长度，UE1在计时过程中，确定sTTI4中包含DMRS，则在sTTI3的结束位置结束计时，在结束计时之前一直保持锁相环开启。结束计时之后，在sTTI4中以及以后的sTTI中是否还需要保持锁相环开启，可以按照上述sTTI1类似的方式进行判断。Method 3: UE1 determines that sTTI1 includes a symbol for transmitting DMRS, and UE1 determines to start a timer at an end position or a start position of sTTI1, and the timing duration is 1 subframe or 6 sTTI length, and UE1 determines sTTI4 during timing. The DMRS is included, and the timing ends at the end of sTTI3, and the phase locked loop is kept open until the end of the timing. After the end of the timer, whether the phase-locked loop needs to be turned on in sTTI4 and later sTTI can be judged in a similar manner to the above sTTI1.

在上述实施例中UE确定是否保持锁相环开启时，可以只确定用于传输DMRS的符号的时间单元，从而采用上述方法来确定是否保持锁相环开启。另外，UE在确定是否保持锁相环开启时，还可以根据用于传输数据的时间单元k2以及该数据所对应的DMRS所在的时间单元k1，来确定是否保持锁相环开启。具体的，所述UE根据传输情况，确定是否保持锁相环开启包括：如果UE确定时间单元k2中数据传输所对应的DMRS在时间单元k1中传输时，所述UE确定是否保持锁相环开启包括至少如下方法之一：In the foregoing embodiment, when the UE determines whether to keep the phase locked loop open, only the time unit for transmitting the symbol of the DMRS may be determined, thereby determining whether to keep the phase locked loop open by using the above method. In addition, when determining whether to keep the phase locked loop open, the UE may further determine whether to keep the phase locked loop open according to the time unit k2 for transmitting data and the time unit k1 where the DMRS corresponding to the data is located. Specifically, the determining, by the UE, whether to keep the phase locked loop open according to the transmission situation includes: if the UE determines that the DMRS corresponding to the data transmission in the time unit k2 is transmitted in the time unit k1, the UE determines whether to keep the phase locked loop open. Includes at least one of the following methods:

UE确定在所述时间单元k1到所述时间单元k2的时间间隔之间保持锁相环开启；The UE determines to keep the phase locked loop open between the time interval from the time unit k1 to the time unit k2;

UE从所述时间单元k1的结束位置到所述时间单元k1或所述时间单元k2所在的时隙或子帧的结束位置保持锁相环开启；The UE keeps the phase locked loop from the end position of the time unit k1 to the end position of the time slot k1 or the time slot or subframe where the time unit k2 is located;

UE从所述时间单元k1的开始位置到所述时间单元k1或所述时间单元k2所在的时隙或子帧的结束位置保持锁相环开启。The UE keeps the phase locked loop open from the start position of the time unit k1 to the end position of the time slot or subframe in which the time unit k1 or the time unit k2 is located.

如图2A所示的UE传输数据和DMRS的示意图，UE1确定sTTI3中数据传输所对应的DMRS在sTTI1中传输时，则UE1确定在sTTI1到sTTI3的时间间隔之间保持锁相环开启，即在sTTI2中保持锁相环开启，因为sTTI1和sTTI3中本身存在传输，在sTTI1和sTTI3本身就会保持锁相环开启，sTTI3之后锁相环的状态则取决于其后的sTTI的具体传输情况，判断方式与上述过程类似。As shown in FIG. 2A, the UE transmits data and DMRS, and when UE1 determines that the DMRS corresponding to the data transmission in sTTI3 is transmitted in sTTI1, UE1 determines to keep the phase-locked loop open between the time intervals of sTTI1 to sTTI3, that is, In sTTI2, the phase-locked loop is kept open. Because sTTI1 and sTTI3 have transmissions themselves, the phase-locked loops are kept open in sTTI1 and sTTI3. The state of the phase-locked loop after sTTI3 depends on the specific transmission condition of the subsequent sTTI. The way is similar to the above process.

如图2B所示的UE传输数据和DMRS的示意图，UE1确定sTTI3中数据传输所对应的DMRS在sTTI1中传输时，则UE1确定在sTTI1到sTTI3的时间间隔之间保持锁相环开启。具体的，时间单元可以是sTTI级别，因为sTTI1中在一个符号上存在传输，则在sTTI1中UE本身就会保持锁相环开启，因此在sTTI1到sTTI3的时间间隔之间保持锁相环开启可以理解为，仅需要在sTTI2中保持锁相环开启即可；或时间单元可以是符号级别，因为sTTI1的第一个符号和sTTI3中本身存在传输，UE本身就会在sTTI1的第一个符号和sTTI3中保持锁相环开启，其余不存在传输的符号和sTTI中为节省功率锁相环关闭，因此在sTTI1到sTTI3的时间间隔之间保持锁相环开启可以理解为，需在sTTI1中的第二和第三个符号以及sTTI2中保持锁相环开启。As shown in FIG. 2B, the UE transmits data and DMRS. When UE1 determines that the DMRS corresponding to the data transmission in sTTI3 is transmitted in sTTI1, UE1 determines to keep the phase-locked loop open between the time intervals of sTTI1 to sTTI3. Specifically, the time unit may be an sTTI level. Because there is a transmission on one symbol in sTTI1, the UE itself keeps the phase-locked loop open in sTTI1, so the phase-locked loop is kept open between the intervals of sTTI1 to sTTI3. It is understood that it is only necessary to keep the phase-locked loop open in sTTI2; or the time unit can be at the symbol level, because the first symbol of sTTI1 and the transmission itself in sTTI3, the UE itself will be in the first symbol of sTTI1 and In sTTI3, the phase-locked loop is kept open, and the remaining symbols are not transmitted and the power-locked loop is closed in the sTTI. Therefore, keeping the phase-locked loop open between sTTI1 and sTTI3 can be understood as the first in sTTI1. The second and third symbols, as well as the sTTI2, keep the phase-locked loop open.

sTTI3之后锁相环的状态则取决于其后的sTTI的具体传输情况，判断方式与上述过程类似。The state of the phase-locked loop after sTTI3 depends on the specific transmission condition of the subsequent sTTI, and the judgment manner is similar to the above process.

在上述实施例中，只要确定了时间单元k1和时间单元k2后，则无论时间单元k1和时间单元k2之间是否存在传输，为了保持相位连续，都可以在时间单元k1和时间单元k2之间保持锁相环开启。但实际上在使用时，可能时间单元k1和时间单元k2之间存在传输，则UE的锁相环一定是保持开启的，此时即使不采用本发明实施例的控制方法，相位也是连续的。因此为了达到省电的效果，所述UE确定是否保持锁相环开启之前，采用如下方法之一：In the above embodiment, as long as the time unit k1 and the time unit k2 are determined, whether there is transmission between the time unit k1 and the time unit k2, in order to maintain the phase continuity, between the time unit k1 and the time unit k2 Keep the phase-locked loop open. However, in practice, there may be a transmission between the time unit k1 and the time unit k2, and the phase-locked loop of the UE must remain open. At this time, the phase is continuous even if the control method of the embodiment of the present invention is not used. Therefore, in order to achieve the effect of power saving, the UE determines whether to keep the phase locked loop open, and adopts one of the following methods:

判断所述时间单元k1与所述时间单元k2之间是否存在传输，如果否，进行后续步骤(即采用上述方法确定保持锁相环开启)；或，判断所述时间单元k1中传输DMRS的符号，与所述时间单元k2之间是否存在传输，如果否，进行后续步骤(即采用上述方法确定保持锁相环开启)。Determining whether there is a transmission between the time unit k1 and the time unit k2, if not, performing a subsequent step (ie, determining to keep the phase locked loop open by using the above method); or determining a symbol for transmitting the DMRS in the time unit k1 Whether there is a transmission between the time unit k2 and, if not, performing a subsequent step (ie, determining to keep the phase locked loop open by using the above method).

当UE判断所述时间单元k1与所述时间单元k2之间不存在传输，或所述时间单元k1中传输DMRS的符号，与所述时间单元k2之间不存在传输时，UE确定是否保持锁相环开启，具体的可采用如下任意一种方法：When the UE determines that there is no transmission between the time unit k1 and the time unit k2, or transmits a symbol of the DMRS in the time unit k1, and there is no transmission between the time unit k2, the UE determines whether to keep the lock. The phase loop is turned on, and any one of the following methods can be used:

UE确定在所述时间单元k1到所述时间单元k2的时间间隔之间保持锁相环开启；The UE determines to keep the phase locked loop open between the time interval from the time unit k1 to the time unit k2;

UE从所述时间单元k1的结束位置到所述时间单元k1或所述时间单元k2所在的时隙或子帧的结束位置保持锁相环开启；The UE keeps the phase locked loop from the end position of the time unit k1 to the end position of the time slot k1 or the time slot or subframe where the time unit k2 is located;

UE从所述时间单元k1的开始位置到所述时间单元k1或所述时间单元k2所在的时隙或子帧的结束位置保持锁相环开启。The UE keeps the phase locked loop open from the start position of the time unit k1 to the end position of the time slot or subframe in which the time unit k1 or the time unit k2 is located.

并且UE可以在所述时间单元k1与所述时间单元k2的时间间隔之间关闭射频芯片PA等射频器件，以达到省电的效果。And the UE can turn off the radio frequency device such as the radio frequency chip PA between the time interval of the time unit k1 and the time unit k2 to achieve the power saving effect.

如图2A所示的UE传输数据和DMRS的示意图，UE1确定sTTI3中数据传输所对应的DMRS在sTTI1中传输时，且判断出UE1在sTTI1到sTTI3的时间间隔之间即sTTI2中不存在传输时，则UE1确定在sTTI1到sTTI3的时间间隔之间保持锁相环开启，即在sTTI2中保持锁相环开启，因为sTTI1和sTTI3中本身存在传输，UE1在sTTI1和sTTI3中本身就会保持锁相环开启。sTTI3之后锁相环的状态则取决于其后的sTTI的具体传输情况，判断方式与上述过程类似。As shown in FIG. 2A, the UE transmits data and DMRS, and UE1 determines that the DMRS corresponding to the data transmission in sTTI3 is transmitted in sTTI1, and determines that UE1 does not exist in the interval between sTTI1 and sTTI3, that is, in sTTI2. Then, UE1 determines to keep the phase-locked loop open between the time intervals of sTTI1 and sTTI3, that is, keep the phase-locked loop open in sTTI2, because there is transmission in sTTI1 and sTTI3, UE1 itself remains locked in sTTI1 and sTTI3. The ring is open. The state of the phase-locked loop after sTTI3 depends on the specific transmission condition of the subsequent sTTI, and the judgment manner is similar to the above process.

如图2B所示的UE传输数据和DMRS的示意图，UE1确定sTTI3中数据传输所对应的DMRS在sTTI1中传输，且UE1在sTTI2和/或sTTI1的第二个和第三个符号中不存在传输时，则UE1确定在sTTI1到sTTI3的时间间隔之间保持锁相环开启，具体的，时间单元可以是sTTI级别，因为sTTI1中在一个符号上存在传输，则在sTTI1中UE本身就会保持锁相环开启，因此在sTTI1到sTTI3的时间间隔之间保持锁相环开启可以理解为，仅需 要在sTTI2中保持锁相环开启即可；或时间单元可以是符号级别，因为sTTI1的第一个符号和sTTI3中本身存在传输，UE本身就会在sTTI1的第一个符号和sTTI3中保持锁相环开启，其余不存在传输的符号和sTTI中为节省功率锁相环关闭，因此在sTTI1到sTTI3的时间间隔之间保持锁相环开启可以理解为，需在sTTI1中的第二和第三个符号以及sTTI2中保持锁相环开启。As shown in FIG. 2B, the UE transmits data and DMRS, and UE1 determines that the DMRS corresponding to the data transmission in sTTI3 is transmitted in sTTI1, and UE1 does not transmit in the second and third symbols of sTTI2 and/or sTTI1. The UE1 determines to keep the phase-locked loop open between the time intervals of sTTI1 and sTTI3. Specifically, the time unit may be the sTTI level. Because there is transmission on one symbol in sTTI1, the UE itself remains locked in sTTI1. The phase loop is turned on, so keeping the phase locked loop open between the time intervals of sTTI1 and sTTI3 can be understood as that only the phase locked loop needs to be kept open in sTTI2; or the time unit can be symbol level because the first one of sTTI1 The symbol and sTTI3 have their own transmission. The UE itself keeps the phase-locked loop open in the first symbol of sTTI1 and sTTI3. The rest of the transmitted symbols and sTTI are closed for saving power phase-locked loop, so sTTI1 to sTTI3 Keeping the phase-locked loop open between the time intervals can be understood as the need to keep the phase-locked loop open in the second and third symbols in sTTI1 and in sTTI2.

sTTI3之后PLL的状态则取决于其后的sTTI的具体传输情况，判断方式与上述过程类似。The state of the PLL after sTTI3 depends on the specific transmission condition of the subsequent sTTI, and the judgment mode is similar to the above process.

在本发明实施例中时间单元可以是第七数量个符号，或第八数量个微时隙，或第九数量个sTTI，或第十数量个时隙，或第十一数量个子帧，其中，所述第七数量、第八数量、第九数量、第十数量和第十一数量为不小于1的整数。In the embodiment of the present invention, the time unit may be a seventh number of symbols, or an eighth number of minislots, or a ninth number of sTTIs, or a tenth number of slots, or an eleventh number of subframes, where The seventh number, the eighth number, the ninth number, the tenth number, and the eleventh number are integers not less than one.

实施例3：Example 3:

为了实现灵活配置，UE在确定是否保持锁相环开始时，还可以根据配置信令的配置来确定，具体的，所述UE根据配置信令的配置，确定是否保持锁相环开启包括：UE接收配置信令，根据所述配置信令的指示确定是否保持锁相环开启。In order to implement the flexible configuration, the UE may determine, according to the configuration of the configuration signaling, whether the UE maintains the phase-locked loop, and specifically, the UE determines whether to keep the phase-locked loop open according to the configuration of the configuration signaling, including: Receiving configuration signaling, determining whether to keep the phase locked loop open according to the indication of the configuration signaling.

其中该配置信令为网络侧设备发送给UE的，例如可以是演进节点B(evovled NodeB，eNB，即基站)发送的。The configuration signaling is sent by the network side device to the UE, for example, it may be sent by an evovled NodeB (eNB, ie, a base station).

具体的，所述UE接收配置信令，根据所述配置信令的指示确定是否保持锁相环开启采用如下方法之一：Specifically, the UE receives the configuration signaling, and determines whether to keep the phase locked loop open according to the indication of the configuration signaling:

UE接收高层信令，根据所述高层信令的指示确定是否保持锁相环开启；The UE receives the high layer signaling, and determines, according to the indication of the high layer signaling, whether to keep the phase locked loop open;

UE接收下行控制信道，根据所述下行控制信道中的指示域确定是否保持锁相环开启。The UE receives the downlink control channel, and determines whether to keep the phase locked loop open according to the indication field in the downlink control channel.

UE在根据所述高层信令的指示确定是否保持锁相环开启时，具体的可以是，网络侧设备(eNB)预先会判断该UE的传输情况，向该UE发送高层信令，通过高层信令配置UE是否保持锁相环开启，当UE接收到该高层信令时，如果该高层信令指示UE保持锁相环开启，则UE保持锁相环开启，如果UE接收到高层信令指示UE关闭锁相环，则UE关闭锁相环。When the UE determines whether to keep the phase locked loop open according to the indication of the high layer signaling, the network side device (eNB) may determine the transmission condition of the UE in advance, and send high layer signaling to the UE, and pass the high layer letter. If the UE receives the high-level signaling, if the UE indicates that the UE keeps the phase-locked loop open, the UE keeps the phase-locked loop open, and if the UE receives the high-level signaling, the UE is instructed to When the phase locked loop is closed, the UE turns off the phase locked loop.

其中，所述高层信令可以为无线资源控制(Radio Resource Control，RRC)信令，也可以为媒体访问控制(Media Access Control，MAC CE)信令。The high-level signaling may be Radio Resource Control (RRC) signaling or Media Access Control (MAC CE) signaling.

例如，如图2A或2B所示的终端传输数据和DMRS的示意图，UE1接收高层信令，根据高层信令的指示确定是否保持锁相环开启。具体的，eNB预先判断会对UE1进行类似图2A或图2B的调度，则预先通过高层信令配置UE1是否保持锁相环开启，当UE接收到该高层信令时，如果该高层信令指示UE保持锁相环开启，则UE1保持锁相环开启，如 果UE接收到高层信令指示UE关闭锁相环，则UE关闭锁相环。For example, as shown in FIG. 2A or 2B, the terminal transmits data and a schematic diagram of the DMRS, and the UE1 receives the high layer signaling, and determines whether to keep the phase locked loop open according to the indication of the high layer signaling. Specifically, the eNB pre-determines that the UE1 performs scheduling similar to that of FIG. 2A or FIG. 2B, and then configures whether the UE1 keeps the phase-locked loop open by using the high-layer signaling, and when the UE receives the high-layer signaling, if the high-layer signaling indicates The UE keeps the phase locked loop open, and the UE1 keeps the phase locked loop open. If the UE receives the high layer signaling to indicate that the UE turns off the phase locked loop, the UE turns off the phase locked loop.

UE在根据配置信令，确定是否保持锁相环开启时，还可以是根据接收到的下行控制信道中的指示域确定是否保持锁相环开启。When determining whether to keep the phase locked loop open according to the configuration signaling, the UE may further determine whether to keep the phase locked loop open according to the indication field in the received downlink control channel.

其中下行控制信道中的指示域可以总是有效，也可以是仅在特定条件下有效。当指示域可以总是有效时，则UE需要总是获取指示域的指示内容，即UE需要在下行控制信道所调度的每个时间单元中获取指示域的指示内容；当指示域在特定条件下有效时，UE只需要在特定条件下获取指示域的指示内容，例如可以是当该下行控制信道所调度的时间单元中包含用于传输DMRS的符号时有效，则此时UE需要获取指示域的指示内容。The indication field in the downlink control channel may be always valid, or may be valid only under certain conditions. When the indication field can always be valid, the UE needs to always obtain the indication content of the indication domain, that is, the UE needs to obtain the indication content of the indication domain in each time unit scheduled by the downlink control channel; when the indication domain is under certain conditions When the UE is valid, the UE only needs to obtain the indication content of the indication domain under certain conditions, for example, when the time unit scheduled by the downlink control channel includes the symbol for transmitting the DMRS, the UE needs to acquire the indication domain. Indicate the content.

所述下行控制信道为使用上行下行控制信息(Downlink control information，DCI)格式的下行控制信道或使用下行DCI格式的下行控制信道。The downlink control channel is a downlink control channel using a Downlink Control Information (DCI) format or a downlink control channel using a downlink DCI format.

所述下行控制信道用于调度至少一个时间单元。The downlink control channel is configured to schedule at least one time unit.

在本发明实施例中下行控制信道的指示域不仅可以指示UE是否保持锁相环开启，在该指示域中还可以指示UE保持锁相环开启的时间长度，其中当下行控制信道中还存在指示域指示UE保持锁相环开启的时间长度，所述根据所述下行控制信道中的指示域确定是否保持锁相环开启包括：UE确定在时间单元k4所在的时隙或子帧中保持锁相环开启，或UE确定从时间单元k4的结束位置到所述时间单元k4所在的时隙或子帧的结束位置保持锁相环开启，或UE确定从时间单元k4的开始位置到所述时间单元k4所在的时隙或子帧的结束位置保持锁相环开启。其中，所述时间单元k4为所述下行控制信道所对应的时间单元。In the embodiment of the present invention, the indication field of the downlink control channel may not only indicate whether the UE keeps the phase-locked loop open, but also indicates, in the indication field, the length of time that the UE keeps the phase-locked loop open, where there is still an indication in the downlink control channel. The field indicates the length of time that the UE keeps the phase locked loop open, and determining whether to keep the phase locked loop open according to the indication field in the downlink control channel includes: determining, by the UE, that the phase lock is maintained in the time slot or subframe in which the time unit k4 is located The loop is turned on, or the UE determines that the phase locked loop is turned on from the end position of the time unit k4 to the end position of the time slot or subframe in which the time unit k4 is located, or the UE determines from the start position of the time unit k4 to the time unit The slot where k4 is located or the end position of the subframe keeps the phase locked loop open. The time unit k4 is a time unit corresponding to the downlink control channel.

例如，如图2A或2B所示的终端传输数据和DMRS的示意图，UE1根据所述下行控制信道的指示域确定保持锁相环开启的时间长度，按照该时间长度保持锁相环开启。For example, as shown in FIG. 2A or 2B, the UE transmits a data and a DMRS. The UE1 determines, according to the indication field of the downlink control channel, the length of time for keeping the phase-locked loop open, and keeps the phase-locked loop open according to the length of time.

如果下行控制信道的指示域中不存在指示域指示UE保持锁相环开启的时间长度，则所述UE接收下行控制信道，根据所述下行控制信道中的指示域确定是否保持锁相环开启包括：当UE根据所述下行控制信道中的指示确定保持锁相环开启时，UE在所述下行控制信道所对应的时间单元k4的开始位置或结束位置保持锁相环开启，直到接收到的新的下行控制信道所对应的时间单元k5。If the indication field in the downlink control channel does not exist, the UE indicates that the UE keeps the phase-locked loop open, and the UE receives the downlink control channel, and determines whether to keep the phase-locked loop open according to the indication field in the downlink control channel. When the UE determines to keep the phase-locked loop open according to the indication in the downlink control channel, the UE keeps the phase-locked loop open at the start position or the end position of the time unit k4 corresponding to the downlink control channel, until the new received The time unit k5 corresponding to the downlink control channel.

如图2A所示的UE传输数据和DMRS的示意图，UE1根据所述下行控制信道中的指示，确定从sTTI1的结束位置保持锁相环开启，直到接收到的新的下行控制信道所对应的sTTIy，在该sTTIy开始是否保持锁相环开启可以根据该sTTIy所对应的下行控制信道确定。As shown in FIG. 2A, the UE transmits data and DMRS according to the indication in the downlink control channel, and determines that the phase-locked loop is kept from the end position of the sTTI1 until the sTTIy corresponding to the received new downlink control channel. Whether to keep the phase locked loop open at the beginning of the sTTIy may be determined according to the downlink control channel corresponding to the sTTIy.

如图2B所示的UE传输数据和DMRS的示意图，UE1根据所述下行控制信道中的指示，确定从sTTI1的结束位置保持锁相环开启，或从sTTI1中的用于传输DMRS的符号的 结束位置保持锁相环开启，直到接收到的新的下行控制信道所对应的sTTIy，在该sTTIy开始是否保持锁相环开启，可以根据该sTTIy所对应的下行控制信道确定。As shown in FIG. 2B, the UE transmits data and DMRS, and the UE1 determines, according to the indication in the downlink control channel, that the phase-locked loop is kept from the end position of the sTTI1, or the end of the symbol for transmitting the DMRS from the sTTI1. The location keeps the phase-locked loop open until the sTTIy corresponding to the received new downlink control channel starts to maintain the phase-locked loop at the beginning of the sTTIy, and can be determined according to the downlink control channel corresponding to the sTTIy.

在上述实施例中，时间单元可以是sTTI级别，当UE1确定从sTTI1的结束位置保持锁相环开启时，因为sTTI1本身在一个符号上存在传输，则在sTTI1中UE1本身就会保持锁相环开启。In the above embodiment, the time unit may be an sTTI level. When UE1 determines to keep the phase locked loop from being turned on from the end position of sTTI1, since sTTI1 itself has transmission on one symbol, UE1 itself keeps the phase locked loop in sTTI1. Open.

时间单元也可以是符号级别，当UE1确定从sTTI1中的用于传输DMRS的符号的结束位置保持锁相环开启时，因为sTTI1中仅在第一个符号存在传输，则第一个符号上UE1本身就会保持锁相环开启。The time unit may also be a symbol level. When the UE1 determines to keep the phase-locked loop from being turned on from the end position of the symbol for transmitting the DMRS in sTTI1, since there is only transmission in the first symbol in sTTI1, the UE1 on the first symbol It will keep the phase-locked loop open.

如果下行控制信道的指示域中不存在指示域指示UE保持锁相环开启的时间长度，则所述UE接收下行控制信道，根据所述下行控制信道中的指示域确定是否保持锁相环开启还可以包括：当UE根据所述下行控制信道中的指示确定保持锁相环开启时，UE确定在时间单元k4所在的时隙或子帧中保持锁相环开启；或UE确定从时间单元k4的开始位置到时间单元k4所在的时隙或子帧的结束位置保持锁相环开启；或UE确定从时间单元k4的结束位置到时间单元k4所在的时隙或子帧的结束位置保持锁相环开启。其中，所述时间单元k4为所述下行控制信道所对应的时间单元。If the indication field in the downlink control channel does not exist, the UE indicates that the UE keeps the phase-locked loop open, and the UE receives the downlink control channel, and determines whether to keep the phase-locked loop open according to the indication field in the downlink control channel. The method may include: when the UE determines to keep the phase locked loop open according to the indication in the downlink control channel, the UE determines to keep the phase locked loop open in the time slot or subframe in which the time unit k4 is located; or the UE determines the slave time unit k4 The start position to the end of the time slot or subframe where the time unit k4 is located keeps the phase locked loop open; or the UE determines to keep the phase locked loop from the end position of the time unit k4 to the end position of the time slot or subframe in which the time unit k4 is located Open. The time unit k4 is a time unit corresponding to the downlink control channel.

如图2A所示的UE传输数据和DMRS的示意图，UE1确定从sTTI1的结束位置开始，直到sTTI1所在的slot或子帧的结束位置保持锁相环开启。因为sTTI1本身存在传输，所以在sTTI1中锁相环开启。在该sTTI1所在的slot或子帧之后，UE1是否继续保持锁相环开启取决于后一个slot或子帧中的每个sTTI的调度和传输情况，具体判断方式与该sTTI1所在的slot或子帧类似。As shown in FIG. 2A, the UE transmits data and DMRS, and UE1 determines to start from the end position of sTTI1 until the end of the slot or subframe where sTTI1 is located to keep the phase-locked loop open. Since sTTI1 itself has a transmission, the phase-locked loop is turned on in sTTI1. After the slot or subframe in which the sTTI1 is located, whether UE1 continues to keep the phase locked loop on depends on the scheduling and transmission of each sTTI in the latter slot or subframe, and the specific judgment manner is the slot or subframe in which the sTTI1 is located. similar.

如图2B所示的终端传输数据和DMRS的示意图，UE1确定从sTTI1的结束位置或sTTI1中的用于传输DMRS的符号的结束位置保持锁相环开启，直到sTTI1所在的slot或子帧的结束位置。在该sTTI1所在的slot或子帧之后，是否继续保持锁相环开启取决于后一个slot中的每个sTTI的调度和传输情况，具体判断方式与该sTTI1所在的slot或子帧类似。As shown in the schematic diagram of the terminal transmission data and the DMRS shown in FIG. 2B, the UE1 determines to keep the phase-locked loop from being opened from the end position of the sTTI1 or the end position of the symbol for transmitting the DMRS in the sTTI1 until the end of the slot or subframe where the sTTI1 is located position. After the slot or subframe where the sTTI1 is located, whether to keep the phase-locked loop open depends on the scheduling and transmission of each sTTI in the latter slot, and the specific determination manner is similar to the slot or subframe in which the sTTI1 is located.

当UE1确定从在sTTI1的结束位置开始保持锁相环开启时，时间单元可以是sTTI级别，因为sTTI1本身在一个符号上存在传输，则在sTTI1中UE1本身就保持锁相环开启。When UE1 determines that the phase locked loop is turned on from the end position of sTTI1, the time unit may be the sTTI level, and since sTTI1 itself has transmission on one symbol, UE1 itself keeps the phase locked loop open in sTTI1.

当UE1确定从sTTI1中的用于传输DMRS的符号的结束位置开始保持锁相环开启时，时间单元可以是符号级别，因为sTTI1中仅在第一个符号存在传输，则UE1本身在第一个符号上必然保持锁相环开启。When UE1 determines to keep the phase locked loop open from the end position of the symbol for transmitting the DMRS in sTTI1, the time unit may be the symbol level, because there is only transmission in the first symbol in sTTI1, UE1 itself is in the first The symbol phase must keep the phase locked loop open.

如果下行控制信道的指示域中不存在指示域指示UE保持锁相环开启的时间长度，则 所述UE接收下行控制信道，根据所述下行控制信道中的指示域确定是否保持锁相环开启还可以包括：当UE根据所述下行控制信道中的指示确定保持锁相环开启时，如果UE确定时间单元k6中数据传输所对应的DMRS在时间单元k4中传输时，执行以下方法之一：If the indication field in the downlink control channel does not exist, the UE indicates that the UE keeps the phase-locked loop open, and the UE receives the downlink control channel, and determines whether to keep the phase-locked loop open according to the indication field in the downlink control channel. The method may include: when the UE determines to keep the phase locked loop open according to the indication in the downlink control channel, if the UE determines that the DMRS corresponding to the data transmission in the time unit k6 is transmitted in the time unit k4, perform one of the following methods:

UE确定在所述时间单元k4到所述时间单元k6的时间间隔之间保持锁相环开启；The UE determines to keep the phase locked loop open between the time interval from the time unit k4 to the time unit k6;

UE确定从所述时间单元k4的结束位置到所述时间单元k4或所述时间单元k6所在的时隙或子帧的结束位置保持锁相环开启；Determining, by the UE, that the phase locked loop is turned on from the end position of the time unit k4 to the end position of the time slot or subframe in which the time unit k4 or the time unit k6 is located;

UE确定从所述时间单元k4的开始位置到所述时间单元k4或所述时间单元k6所在的时隙或子帧的结束位置保持锁相环开启。The UE determines that the phase locked loop is turned on from the start position of the time unit k4 to the end position of the time slot or subframe in which the time unit k4 or the time unit k6 is located.

其中，所述时间单元k4和所述时间单元k6为所述下行控制信道所对应的时间单元。The time unit k4 and the time unit k6 are time units corresponding to the downlink control channel.

如图2A所示的UE传输数据和DMRS的示意图，UE1根据sTTI3对应的下行控制信道确定sTTI3中数据传输所对应的DMRS在sTTI1中传输，则UE1确定在sTTI1到sTTI3的时间间隔之间保持锁相环开启，即在sTTI2中保持锁相环开启，因为sTTI1和sTTI3中本身存在传输，在sTTI1和sTTI3中UE1本身就会保持锁相环开启，sTTI3之后锁相环的状态则取决于其后的sTTI的具体传输情况，判断方式与上述过程类似。As shown in FIG. 2A, the UE transmits data and DMRS as shown in FIG. 2A. The UE1 determines that the DMRS corresponding to the data transmission in the sTTI3 is transmitted in the sTTI1 according to the downlink control channel corresponding to the sTTI3, and the UE1 determines to keep the lock between the time intervals of sTTI1 to sTTI3. The phase loop is enabled, that is, the phase-locked loop is kept open in sTTI2. Because there is transmission in sTTI1 and sTTI3, UE1 itself keeps the phase-locked loop open in sTTI1 and sTTI3, and the state of the phase-locked loop after sTTI3 depends on it. The specific transmission situation of the sTTI is judged in a similar manner to the above process.

如图2B所示的UE传输数据和DMRS的示意图，UE1根据sTTI3对应的下行控制信道确定sTTI3中数据传输所对应的DMRS在sTTI1中传输，则UE1确定在sTTI1到sTTI3的时间间隔之间保持锁相环开启。具体的，时间单元可以是sTTI级别，因为sTTI1中在一个符号上存在传输，则在sTTI1中UE本身就会保持锁相环开启，因此在sTTI1到sTTI3的时间间隔之间保持锁相环开启可以理解为，仅需要在sTTI2中保持锁相环开启即可；或时间单元可以是符号级别，因为sTTI1的第一个符号和sTTI3中本身存在传输，UE本身就会在sTTI1的第一个符号和sTTI3中保持锁相环开启，其余不存在传输的符号和sTTI中为节省功率锁相环关闭，因此在sTTI1到sTTI3的时间间隔之间保持锁相环开启可以理解为，需在sTTI1中的第二和第三个符号以及sTTI2中保持锁相环开启。As shown in FIG. 2B, the UE transmits data and DMRS according to the downlink control channel corresponding to sTTI3, and determines that the DMRS corresponding to the data transmission in sTTI3 is transmitted in sTTI1, and UE1 determines to keep the lock between the time intervals of sTTI1 to sTTI3. The phase ring is turned on. Specifically, the time unit may be an sTTI level. Because there is a transmission on one symbol in sTTI1, the UE itself keeps the phase-locked loop open in sTTI1, so the phase-locked loop is kept open between the intervals of sTTI1 to sTTI3. It is understood that it is only necessary to keep the phase-locked loop open in sTTI2; or the time unit can be at the symbol level, because the first symbol of sTTI1 and the transmission itself in sTTI3, the UE itself will be in the first symbol of sTTI1 and In sTTI3, the phase-locked loop is kept open, and the remaining symbols are not transmitted and the power-locked loop is closed in the sTTI. Therefore, keeping the phase-locked loop open between sTTI1 and sTTI3 can be understood as the first in sTTI1. The second and third symbols, as well as the sTTI2, keep the phase-locked loop open.

sTTI3之后PLL的状态则取决于其后的sTTI的具体传输情况，判断方式与上述过程类似。The state of the PLL after sTTI3 depends on the specific transmission condition of the subsequent sTTI, and the judgment mode is similar to the above process.

如果下行控制信道的指示域中不存在指示域指示UE保持锁相环开启的时间长度，则所述UE接收下行控制信道，根据所述下行控制信道中的指示域确定是否保持锁相环开启还可以包括：当UE根据所述下行控制信道中的指示确定保持锁相环开启时，UE启动定时器，在预设的计时时长内一直保持锁相环开启；或UE启动定时器，在计时过程中，确定所述时间单元k4之后的时间单元k7中包含用于传输DMRS的符号时，结束计时，在结束计时之前一直保持锁相环开启，其中，所述时间单元k4和所述时间单元k7为所述下行控 制信道所对应的时间单元，或所述时间单元k4为所述下行控制信道所对应的时间单元，所述时间单元k7为所述下行控制信道之后的另一下行控制信道所对应的时间单元。If the indication field in the downlink control channel does not exist, the UE indicates that the UE keeps the phase-locked loop open, and the UE receives the downlink control channel, and determines whether to keep the phase-locked loop open according to the indication field in the downlink control channel. The method may include: when the UE determines to keep the phase locked loop open according to the indication in the downlink control channel, the UE starts a timer, and keeps the phase locked loop open for a preset time duration; or the UE starts the timer during the timing process. When it is determined that the time unit k7 after the time unit k4 includes a symbol for transmitting the DMRS, the timing is ended, and the phase locked loop is kept open until the end of the timing, wherein the time unit k4 and the time unit k7 a time unit corresponding to the downlink control channel, or the time unit k4 is a time unit corresponding to the downlink control channel, where the time unit k7 is corresponding to another downlink control channel after the downlink control channel Time unit.

如图2A所示的UE传输数据和DMRS的示意图，UE在sTTI1的结束位置启动定时器或开始位置启动定时器，在定时器的计时时长内，在计时结束之前一直保持锁相环开启，如果在sTTI1的开始位置启动定时器，定时器的计时时长则包含sTTI1传输时间，如果在sTTI1的结束位置启动定时器，定时器的计时时长则不包含sTTI1传输时间。As shown in FIG. 2A, the UE transmits a data and a DMRS, and the UE starts a timer or a start position start timer at the end position of the sTTI1. During the timer duration of the timer, the phase locked loop is kept open until the timer ends. The timer is started at the beginning of sTTI1, and the timer duration includes the sTTI1 transmission time. If the timer is started at the end of sTTI1, the timer duration does not include the sTTI1 transmission time.

例如，计时时长为1个slot或3个sTTI长度，则如果UE1在sTTI1的开始位置启动定时器，在定时器的计时时长内一直保持锁相环开启，则在sTTI1所在slot结束位置之前一直保持锁相环开启，如果UE1在sTTI1的结束位置启动定时器，则计时到下一个slot中的相应位置保持锁相环开启，该相应位置满足从sTTI1的结束位置到该位置长度为1个slot的计时时长。For example, if the timer duration is 1 slot or 3 sTTI lengths, if UE1 starts the timer at the start position of sTTI1, the phase-locked loop is kept open for the duration of the timer, and then remains until the slot end position of sTTI1 is maintained. The phase-locked loop is turned on. If the UE1 starts the timer at the end position of the sTTI1, the corresponding position in the next slot is counted to keep the phase-locked loop open, and the corresponding position satisfies the end position from the sTTI1 to the length of the slot. Timing time.

或UE1确定在sTTI1的结束位置或开始位置启动定时器，计时时长为1个子帧或6个sTTI长度，UE1在计时过程中，确定sTTI4中包含DMRS，则在sTTI3的结束位置结束计时，在结束计时之前一直保持锁相环开启。结束计时之后，在sTTI4中以及以后的sTTI中是否还需要保持锁相环开启，可以按照上述sTTI1类似的方式进行判断。Or the UE1 determines to start the timer at the end position or the start position of the sTTI1, and the timing duration is 1 subframe or 6 sTTI lengths. The UE1 determines that the DMRS is included in the sTTI4 during the timing, and ends the timing at the end of the sTTI3. Keep the phase-locked loop open until timing. After the end of the timer, whether the phase-locked loop needs to be turned on in sTTI4 and later sTTI can be judged in a similar manner to the above sTTI1.

如图2B所示的终端传输数据和DMRS的示意图，UE在sTTI1的结束位置，或在sTTI1的开始位置，或在sTTI1中的用于传输DMRS的符号的结束位置，或在sTTI1中的用于传输DMRS的符号的开始位置，启动定时器，在计时结束之前一直保持锁相环开。As shown in FIG. 2B, the terminal transmits data and the DMRS, the UE is at the end position of sTTI1, or at the start position of sTTI1, or the end position of the symbol for transmitting DMRS in sTTI1, or used in sTTI1. The start position of the symbol of the DMRS is transmitted, the timer is started, and the phase locked loop is kept open until the end of the timer.

如果在sTTI1的开始位置启动定时器，sTTI1传输时间包含在定时器的计时时长内，如果在sTTI1的结束位置启动定时器，sTTI1传输时间则不包含在定时器的计时时长内，此时时间单元可以是sTTI级别，因为sTTI1本身在一个符号上存在传输，则在sTTI1中UE1本身就保持锁相环开启。If the timer is started at the beginning of sTTI1, the sTTI1 transmission time is included in the timer duration. If the timer is started at the end of sTTI1, the sTTI1 transmission time is not included in the timer duration. It can be sTTI level, because sTTI1 itself has transmission on one symbol, then UE1 itself keeps the phase-locked loop on in sTTI1.

如果在sTTI1中的用于传输DMRS的符号的开始位置启动定时器，sTTI1中的用于传输DMRS的符号的传输时间包含在定时器的计时时长内，如果在sTTI1中的用于传输DMRS的符号的结束位置启动定时器，sTTI1中的用于传输DMRS的符号的传输时间不包含在定时器的计时时长内，此时时间单元可以是符号级别，因为sTTI1中仅在第一个符号存在传输，则UE1本身在第一个符号上必然保持锁相环开启。If the start position of the symbol for transmitting the DMRS in sTTI1 starts the timer, the transmission time of the symbol for transmitting the DMRS in sTTI1 is included in the timing of the timer, if the symbol for transmitting the DMRS in sTTI1 The end position starts the timer. The transmission time of the symbol used to transmit the DMRS in sTTI1 is not included in the timer duration of the timer. In this case, the time unit can be at the symbol level, because only the first symbol exists in sTTI1. Then UE1 itself must keep the phase locked loop open on the first symbol.

例如，计时时长为1个slot或3个sTTI长度，则如果UE1在sTTI1的开始位置启动定时器，在定时器的计时时长内一直保持锁相环开启，则在sTTI1所在slot结束位置之前一直保持锁相环开启；如果UE1在sTTI1的结束位置启动定时器，则计时到下一个slot中的相应位置保持锁相环开启，该相应位置满足从sTTI1的结束位置到该位置长度为1个slot 的计时时长。For example, if the timer duration is 1 slot or 3 sTTI lengths, if UE1 starts the timer at the start position of sTTI1, the phase-locked loop is kept open for the duration of the timer, and then remains until the slot end position of sTTI1 is maintained. The phase-locked loop is turned on; if UE1 starts the timer at the end position of sTTI1, the corresponding position in the next slot is counted to keep the phase-locked loop open, and the corresponding position satisfies the end position from sTTI1 to the length of the slot. Timing time.

或，UE1确定在sTTI1的结束位置或开始位置启动定时器，计时时长为1个子帧或6个sTTI长度，UE1在计时过程中，确定sTTI4中包含DMRS，则在sTTI3的结束位置结束计时，在结束计时之前一直保持锁相环开启；结束计时之后，在sTTI4中以及以后的sTTI中是否还需要保持锁相环开启，可以按照上述sTTI1类似的方式进行判断。Alternatively, UE1 determines to start a timer at the end position or the start position of sTTI1, and the timing duration is 1 subframe or 6 sTTI lengths. UE1 determines that sRS is included in sTTI4 during the timing, and ends timing at the end of sTTI3. The phase-locked loop is kept open until the end of the timer. After the end of the timer, whether the phase-locked loop needs to be kept in the sTTI4 and later sTTI can be judged in a similar manner to the above sTTI1.
