具体实施方式
为使本公开要解决的技术问题、技术方案和优点更加清楚，下面将结合附图及具体实施例进行详细描述。
参见图1，图1是本公开的一些实施例可应用的网络结构示意图，如图1所示，包括终端11和网络侧设备12，其中，终端11包括多个天线组，其中，附图以终端11包括两个天线组为例，天线组1与网络侧设备12之间存在传播路线1，传播路线1的时延为时延1，天线组2与网络侧设备12之间存在传播路线2，传播路线2的时延为时延2。需要说明的是，附图中仅是以两个天线组与同一个网络侧设备进行通信，对此不作限定，本公开的一些实施例中，终端11的多个天线组可以同时与一个网络侧设备12通信，也可以同时与多个网络侧设备12通信，也可以支持多天线组之间动态的切换通信。
进一步的，终端11可以是用户终端(User Equipment，UE)或者其他终端设备，例如：手机、平板电脑(Tablet Personal Computer)、膝上型电脑(Laptop Computer)、个人数字助理(Personal Digital Assistant，PDA)、移动上网装置(Mobile Internet Device，MID)、可穿戴式设备(Wearable Device)、机器人、车辆等终端侧设备，需要说明的是，在本公开的一些实施例中并不限定终端的具体类型。网络侧设备12可以是基站，例如：宏站、LTE eNB、5G NR NB等；网络侧设备也可以是小站，如低功率节点(Low Power Node，LPN)、pico、femto等小站，或者网络侧设备可以接入点(Access Point，AP)；网络侧设备也可以是中央单元(Central Unit，CU)，或者可以是传输接收点(Transmission Reception Point，TRP)等网络节点。需要说明的是，在本公开的一些实施例中并不限定网络侧设备的具体类型。
请参见图2，图2是本公开的一些实施例提供的一种定时提前配置方法的流程图，如图2所示，包括以下步骤：
201、终端通过N个天线组分别在N个SRS资源集合上，向网络侧设备发送第一SRS，N为大于1的整数；
202、所述终端接收所述网络侧设备发送的第一配置消息，所述第一配置消息用于配置所述N个定时提前，所述N个定时提前分别与所述N个天线组对应，，其中，所述N个定时提前为所述网络侧设备通过所述N个SRS资源集合上的第一SRS测量得到。
本公开的一些实施例中，天线组可以称作天线面板(antenna panel)或者天线端口组(antenna port group)，也就是说，上述N个天线组也可以是N个天线面板(antenna panel)，或者N个天线端口组(antenna port group)。
其中，上述N个定时提前分别与N个SRS资源集合(resource set)对应。具体可以是，天线组与SRS resource set是一一对应的，因此，上述N个定时提前也可以理解为分别与N个SRS resource set对应，即定时提前与SRS resource set一一对应。
另外，本公开的一些实施例中，每个定时提前可以有一个定时提前标识(ID)，不同定时提前的定时提前标识不同，一个定时提前也可以称作一个定时提前标识的定时提前。例如：网络侧设备可以在为终端配置的RRC信息单元服务小区配置(RRC IE ServingCellConfig)为终端配置多个定时提前ID，每个定时提前ID对应一个天线组，或者对应一个SRS resource set。
且上述N个SRS resource set可以是网络侧设备配置给终端，且每个SRS resource set可以配置一个定时提前ID，这样终端发送SRS时，每个SRS resource set从不同的天线组发送，从而测量到上述N个定时提前。
由于终端通过所述N个天线组分别在N个SRS resource set上，向所述网络侧设备发送第一SRS，从而网络侧设备可以测量到不同的天线组(或者称作不同的SRS resource set)的定时提前。
需要说明的是，本公开的一些实施例中并不限定网络侧设备测量SRS得到定时提前的方式，具体可以参见协议中已定义的方式，或者可以是采用后续协议中新引入的方式等。
通过步骤201可以实现网络侧设备通过多个SRS resource set上的SRS测量得到多个天线组的定时提前，并指示给终端，从而终端可以根据指示的定时提前发送对应的上行信号。
另外，上述N个定时提前分别与N个天线组对应可以是，定时提前与天线组是一一对应关系，但在实际应用中，不同天线组对应的定时提前的值可以是相同或者不同的，例如：天线组1对应的定时提前1和天线组2对应的定时提前2的定时提前值是相同或者不同的。
另外，上述第一配置消息可以是无线资源控制(Radio Resource Control，RRC)消息，或者媒体接入控制的控制单元(Media Access Control Control Element，MAC CE)等消息。
需要说明的是，上述第一配置消息用于配置N个定时提前可以是，第一配置消息配置N个定时提前的定时提前值，从而直接更新N个定时提前，或者配置N个定时提前的调整值或者偏移值，以使得终端根据调整值或者偏移值确定并更新这N个定时提前的定时提前。
需要说明的是，本公开的一些实施例中，定时提前可以用N TA表示，或者可以用T TA表示，其中，T TA可以理解为将N TA进行转换后的定时提前值。其中，T TA和N TA之间转换关系可以采用协议中已定义的转换关系，例如：如下转换关系：
T TA＝(N TA+N TA,offset)T c
其中，其中，T c＝1/(Δf max·N f)，Δf max＝480·10 3Hz，N f＝4096，而N TA,offset的值可以按照相关协议的定义如下：
双工模式 N TAoffset
FDD in FR1 or FR2 0
TDD in FR1 25560
TDD in FR2 13763
需要说明的是，上述T TA和N TA之间转换关系仅是一个举例，本公开的一些实施例对此不作限定，例如：T TA和N TA之间转换关系也可以采用后续协议版本新定义的转换关系。
通过上述可知，本公开的一些实施例中，定时提前可以理解为N TA表示定 时提前，也可以理解为T TA表示定时提前，其中，本公开的一些实施例中主要以N TA进行举例说明。
通过上述步骤可以实现为不同的天线组配置对应的定时提前，从而各天线组可以使用各自对应的定时提前，进而提升信号接收质量。
作为一种可选的实施方式，所述第一配置消息用于指示所述N个定时提前的调整值，所述方法还包括：
所述终端依据所述N个定时提前的调整值和所述终端维护的所述N个定时提前，确定并更新所述N个定时提前。
其中，上述N个定时提前可以理解为为N个定时提前标识的定时提前，上述终端维护的所述N个定时提前可以是终端维护的所述N个定时提前标识的定时提前，例如：在上述更新前终端最后一次更新的定时提前，或者称作终端在执行上述更新之前终端当前维护的定时提前。
另外，上述N个定时提前的调整值可以是网络侧设备通过N个SRS resource set上的第一SRS测量得到，例如：网络侧设备通过N个SRS resource set上的第一SRS测量得到的各天线组的定时提前与前次测量的各天线组的定时提前，以确定各个天线组的定时提前的调整值(也可以称作偏移值)，即相比前一次定时提前的偏移值。
例如：当网络侧设备为SRS resource set配置了定时提前ID时，网络侧设备根据每个SRS resource set可以确定对应的定时提前ID的定时提前，当网络侧设备没有为SRS resource set配置定时提前ID时，网络侧设备根据每个SRS resource set可以确定对应SRS resource set ID的定时提前，以确定各SRS resource set对应的定时提前(或者称作各天线组对应的定时提前)。之后，网络侧设备将测量得到的各个天线组的定时提前通知终端，例如：可以通过MAC CE，将定时提前ID对应的定时提前命令指示给终端，也可以通过MAC CE，将SRS resource set ID对应的定时提前命令通知给终端。从而终端根据网络侧设备的通知，可以确定和维护各个定时提前ID或者各个SRS resource set ID对应的定时提前(或者，各个天线组对应的定时提前)。
进一步的，上述N个定时提前的初始定时提前可以相同。
其中，上述定时提前的初始定时提前可以是，定时提前的定时提前初始 值，或者可以是定时提前的调整值(TA)的初始值。
例如：所述方法还包括：
所述终端通过所述N个天线组中的一个或者多个天线，向所述网络侧设备发送第一信号；
所述终端接收所述网络侧设备发送的第一定时提前，所述第一定时提前是所述网络侧设备通过所述第一信号测量得到的定时提前，且所述N个定时提前的初始定时提前为所述网络侧设备发送的第一定时提前。
其中，上述第一信号可以是随机接入信道(Random Access Channel，RACH)，当然，对此不作限定，也可以是其他上行信号，例如：SRS等。
另外，上述一个或者多个天线可以是一个或者多个天线组中的天线。例如：终端可以通过某个天线组向网络侧设备发送RACH，网络侧设备根据终端发送的RACH测量得到该终端的定时提前，然后网络侧设备通过随机接入响应(Random Access Response，RAR)中的定时提前命令(Timing Advance Command)为终端配置该定时提前，该定时提前是各个天线组的定时提前的初始值。
该实施方式中，由于N个定时提前的初始定时提前可以相同，从而可以使得各定时提前以相同的初始定时提前进行开始维护，降低复杂度。当然，本公开的一些实施例中并不限定N个定时提前的初始定时提前是相同，在一些实施方式也可以允许是不同的。
另外，本公开的一些实施例中，N个定时提前标识可以为N个定时提前子组(Timing Advance sub-Group，TASG)标识，从而每个TASG标识对应一个天线组。另外，定时提前也可以称作TASG，或者TASG的定时提前。
其中，网络侧设备可以通过RRC信令为终端配置N个TASG，从而终端可以维护N个定时子组的定时提前，每个定时提前子组可以对应一个天线组，定时提前子组的数目由RRC配置，也可以根据终端的能力确定，或者根据终端的上报确定，每个定时提前子组有一个编号，可以称为定时提前子组ID。
本公开的一些实施例中，TASG也可以是天线面板的分组或者天线组，即可以表征不同的天线组，每个天线组的定时提前可以不同。而TASG ID，也可以是天线面板ID，天线组ID，用于终端区分不同的天线组，每个天线组 的定时提前可以不同。
作为一种可选的实施方式，上述还包括如下至少一项：
所述终端按照PUSCH的定时提前发送PUSCH信号，其中，所述PUSCH的定时提前为：所述网络侧设备指示的定时提前，或者，所述PUSCH关联的SRS对应的定时提前，或者，发送所述PUSCH信号的天线组对应的定时提前；
所述终端按照PUCCH的定时提前发送PUCCH信号，其中，所述PUCCH的定时提前为：所述网络侧设备指示的定时提前，或者，所述PUCCH关联的SRS对应的定时提前，或者，发送所述PUCCH信号的天线组对应的定时提前；
所述终端按照更新后的定时提前发送第二SRS。
其中，上述在所述PUSCH的定时提前为所述网络侧设备指示的定时提前的情况下，所述网络侧设备指示的定时提前可以为在N个定时提前中指示给所述PUSCH的定时提前。例如：对于PUSCH，网络侧设备可以通过下行控制信息(Downlink Control Information，DCI)配置PUSCH的TASG ID。
进一步的，可以在DCI中配置PUSCH的TASG ID，例如：一种可能的方案：DCI中只有一个TASG ID字段，即该TASG ID字段指示的N TA对所有的传输块(transmission block)都是相同的；另一种可能的方案：DCI中每个传输块(transmission block)有一个TASG ID字段，即每个传输块(transmission block)的N TA是不同的，这是因为对于多天线组同时传输，每个天线组可能采用不同的传输块(transmission block)传输，则每个传输块的定时提前是不同的。
另外，上述实施方式中，还可以实现通过相关联的导频(例如：SRS)获得TASG ID，通过TASG ID确定定时提前。例如：定时提前的关联导频是SRS，如通过SRS资源指示(SRS resource indicator，SRI)指示的SRS或者通过传输配置指示(Transmission Configuration Indication，TCI)指示的准共址(Quasi-colocation，QCL)的导频为SRS，则PUSCH的TASG ID与该SRS配置的TASG ID相同，可以不额外指示。
需要说明的是，上述仅是以定时提前标识为TASG ID进行举例，对此并 不作限定。
而在所述PUCCH的定时提前为所述网络侧设备指示的定时提前的情况下，所述网络侧设备指示的定时提前可以为在N个定时提前中指示给所述PUCCH的定时提前。例如：对于PUCCH，可以通过高层信令配置TASG ID，也可以通过物理层信息配置TASG ID，终端通过TASG ID确定定时提前。
以通过RRC IE配置为例：
如每个PUCCH-ResourceSet配置一个TASG ID，具体如下：
Figure PCTCN2020106151-appb-000001
或者每个PUCCH资源(PUCCH-Resource)配置一个TASG ID，具体如下：
Figure PCTCN2020106151-appb-000002
Figure PCTCN2020106151-appb-000003
以通过DCI指示为例：
在标准协议中，DCI格式(DCI format)1_0和1_1中通过PUCCH资源指示(PUCCH resource indicator)指示PUCCH的资源，为了指示发送该PUCCH的定时提前，本公开的一些实施例中，可以在DCI中增加PUCCH TASG-Id的指示(PUCCH tasg indicator)，用于指示PUCCH的发送定时提前。
对于Format 1_0或者Format 1_1，PUCCH resource indicator可以是3比特，而PUCCH tasg indicator可以是2比特，当然，对此不作限定。
上述终端按照更新后的定时提前发送第二SRS可以是，终端按照SRS对应的定时提前更新的值发送对应的SRS。例如：终端接收到MAC CE中的调整值(TA)命令后，可以按照更新之后的定时提前发送SRS。
需要说明的是，本公开的一些实施例中，第一SRS和第二SRS，以及后面的第三SRS可以是相同的SRS或者不同的SRS，第一、第二和第三仅是为了区分不同时间单元发送的SRS，时间单元可以是子帧(subframe)，也可以是时隙(slot)，也可以是符号(symbol)，不做限定。
上述实施方式中，可以实现当网络侧设备指示终端PUSCH发送时的定时提前ID时，终端可以根据指示的定时提前ID确定PUSCH的发送定时提前，当网络侧设备没有指示终端PUSCH发送时的定时提前ID时，终端可以根据PUSCH关联的SRS对应的定时提前ID或者SRS resource set ID或者天线组确定PUSCH的发送定时提前。
当网络侧设备指示终端PUCCH发送时的定时提前ID时，终端可以根据指示的定时提前ID确定PUCCH的发送定时提前，当网络侧设备有通知终端PUCCH发送时的定时提前ID时，终端可以确定发送该PUCCH的天线组是与哪个SRS resource set的发送天线组是相同的，从而根据SRS resource set ID确定定时提前。如果终端无法确定对应的SRS resource set ID，或者终端还没有发送SRS，或者终端还没有获得SRS resource set对应的定时提前命令，则终端采用网络侧设备发送的定时提前组(Timing Advance Group，TAG)MAC CE指示的定时提前发送PUCCH。
下面结合图3对本公开的一些实施例提供的上述多种实施方式进行举例 说明：
如图3所示，终端向网络侧设备发送RACH，网络侧设备根据RACH计算TA初始值，即N个定时提前标识(或者TASG ID)的调整值的初始值，当然，也可以是计算N个定时提前标识的定时提前初始值；
网络侧设备通过随机接入响应(Random Access Response，RAR)发送TA初始值的指示；
终端根据RAR的通知确定TA的初始值，即确定N个定时提前标识(或者TASG ID)的调整值的初始值，或者确定N个定时提前标识的定时提前初始值；
网络侧设备为终端配置多个SRS resource set；
终端采用不同的天线组在不同的SRS resource set上发送SRS；
网络侧设备根据接收到的SRS确定各天线组的定时提前的调整值(TA值)；
网络侧设备向终端指示各天线组的TA值；
终端根据指示的TA值维护各定时提前标识(或者TASG ID)的定时提前，即确定并更新各定时提前标识(或者TASG ID)的定时提前；
之后，终端按照指示的PUSCH和PUCCH的定时提前标识(或者TASG ID)确定发送定时提前，发送PUSCH和/或PUCCH。
作为一种可选的实施方式，所述方法还包括：
所述终端通过所述N个天线组分别在N个SRS资源集合上，向所述网络侧设备发送第三SRS；
所述终端接收所述网络侧设备发送的第二配置消息，所述第二配置消息用于指示第一定时提前的调整值，其中，所述第一定时提前为所述网络侧设备通过所述N个SRS资源集合上的第三SRS测量确定的定时提前发生变化的定时提前；
所述终端依据所述第一定时提前的调整值和所述终端维护的所述第一定时提前，确定并更新所述第一定时提前。
其中，上述第一定时提前可以是一个或者多个，例如：当测量到多个定时提前发生变化时，网络侧设备可以通过上述第二配置消息配置这多个定时 提前的调整值。
该实施方式中，可以实现只配置发生变化的定时提前的调整值，从而降低配置开销。具体的，该实施方式中，可以应用于在步骤201配置N个定时提前之后，后续更新这N个定时提前的场景。
进一步的，所述第一定时提前可以为PUSCH的定时提前，所述终端维护的所述第一定时提前为，所述终端维护的所述PUSCH关联的SRS对应的定时提前。
其中，这里PUSCH关联的SRS对应的定时提前可以是PUSCH关联的SRS对应的SRS resource set或者天线组对应的定时提前。
当然，上述第一定时提前也可以为PUCCH的定时提前，对此不作限定。
下面以三个具体的实施例对本公开的一些实施例提供的定时提前配置方法进行举例说明：
实施例1
该实施例通过高层信令配置在不同天线组上发送上行信号的定时提前N TA，具体可以包括如下：
通过RRC信令为终端配置TASG，终端维护多个定时提前子组的定时提前，每个TASG可以对应一个天线组，TASG的数目由RRC配置，可以根据终端的能力确定，或者根据终端的上报确定。每个TASG有一个编号，可以称为定时提前子组ID。
本实施例中的TASG可以参见前面描述的TASG，此处不作赘述。
可以在RRC配置中增加TASG的配置，包括但不限于的例子如下：
Figure PCTCN2020106151-appb-000004
TASG的数目与终端的天线组数有关，maxNrofTASGs＝4；
终端通过某个天线组向网络侧设备发送RACH，网络侧设备根据终端发送的RACH测量得到该终端的定时提前，然后基站通过RAR中的定时提前 命令Timing Advance Command为终端配置该定时提前，该定时提前是各个天线组的定时提前的初始值。
基站为终端配置多个SRS resource set，并为每个SRS resource set配置一个定时提前子组ID。终端在不同的天线组上发送SRS resource set。基站通过接收各个SRS resource set，测量得到各个TASG ID对应的定时提前，并确定各个TASG ID对应的定时提前与前次测量的各天线组的定时提前(各个天线组的定时提前的初始值可以为根据RACH测量得到的定时提前)确定各个天线组板定时提前的调整值。
每个TASG定时提前命令字由MAC CE配置。MAC层通过Timing Advance Command MAC CE配置每个TASG-Id对应的定时提前。终端收到MAC CE之后，确定各个定时提前子组的定时提前。
MAC CE可以一次更新所有TASG的定时提前，也可以更新部分TASG的定时提前，如下如所示，则每个定时子组的定时提前为：
N TA_new＝N TA_old+(T A-k)·16·64/2 μ
其中，N TA_old为该定时子组维护的定时提前，N TA_new为该定时子组更新后的定时提前，T A表示调整值，k的取值与TA字段的bit数有关，公式可以为下面的任意一种：
k＝2 NrOfTaBits/2-1
k＝2 NrOfTaBits-1-1
k＝2 NrOfTaBits/2
k＝2 NrOfTaBits-1
其中， NrOfTaBits表示TA字段的bit数，举例来说，当TA字段的比特数为6bit时，k可以为31或者32，当TA字段的比特数为5bit时，k可以为15或者16。
需要说明的是，上述T A表示的调整值仅是举例说明，本公开的一些实施例中，网络侧设备配置的调整值也可以是(T A-k)·16·64/2 μ，另外，上述公式中的(T A-k)·16·64/2 μ可以理解为将T A转换为N TA维度的定时提前的调整值，本公开的一些实施例中，T A转换为N TA维度的定时提前的调整值的方式不作限定，例如：可以采用协议中已定义的上述关系，也可以采用后续协议版本中新定义的转换关系。
另外，上述MAC CE的格式可以参见图4所示。
该实施方式中的PUSCH、PUCCH和SRS的定时提前，以及传输可以参见上面实施描述的相关描述，此处不作赘述。
实施例2
该实施例中，通过高层信令(例如：RRC IE或者MAC CE)配置不同SRS resource set的定时提前，SRS resource set ID可以用于区分天线组。
终端通过某个天线组向网络侧设备发送RACH，基站根据终端发送的RACH测量得到该终端的定时提前，然后网络侧设备通过RAR中的定时提前命令Timing Advance Command为终端配置该定时提前，该定时提前是各个天线组的定时提前的初始值。
网络侧设备为终端配置多个SRS resource set。终端在不同的天线组上发送SRS resource set。网络侧设备通过接收各个SRS resource set，测量得到各个SRS resource set对应的定时提前，并确定各个SRS resource set对应的定时提前与前次测量的定时提前(每个SRS resource set的定时提前的初始值为根据RACH测量得到的定时提前)确定各个SRS resource set定时提前的调整值。
当网络侧设备检测到某一个SRS resource set的定时提前存在偏差时，需要通过高层信令通知该SRS resource set对应的定时提前偏移值。
方案一：通过MAC CE配置
通过MAC CE，为每个SRS resource set配置定时提前命令，其中，该MAC CE如图5或图6所示。
终端收到该MAC CE之后，确定对应该SRS resource set的天线组的发送定时提前。
方案二：采用RRC IE配置，可以如下：
Figure PCTCN2020106151-appb-000005
Figure PCTCN2020106151-appb-000006
终端收到该RRC信息元素(Information Element，IE)之后，确定对应发送该SRS resource set的天线组的发送定时提前。
对于PUSCH，可以通过相关联的SRS resource set ID获得定时提前。
对于PUCCH，终端可以确定发送该PUCCH的天线组是与哪个SRS resource set的发送天线组是相同的，从而确定定时提前。如果终端无法确定对应的SRS resource set ID，或者终端还没有发送SRS，或者终端还没有获得SRS resource set对应的定时提前命令，则终端采用TAG MAC CE指示的定时提前发送PUCCH。
实施例3
该实施例中，通过物理层信令DCI来指示PUSCH的定时提前的调整量
在DCI中增加TA字段，用于指示PUSCH的定时提前与关联导频的定时提前的偏移值。
终端通过某个天线组向基站发送RACH，网络侧设备根据终端发送的RACH测量得到该终端的定时提前，然后网络侧设备通过RAR中的定时提前命令Timing Advance Command为终端配置该定时提前，该定时提前为初始值。
网络侧设备为终端配置多个SRS resource set。网络侧设备在不同的天线组上发送SRS resource set对应的SRS。网络侧设备通过在各个SRS resource set接收SRS，测量得到各个SRS resource set对应的定时提前。当网络侧设备接收SRS测量得到的定时提前发生变化时，需要通知与该PUSCH相关联的PUSCH的定时时延发生改变，则在DCI中增加TA字段，用于指示PUSCH的定时提前与关联导频的定时提前的调整值。终端接收到该DCI中信息后，根据SRS的定时提前和DCI中指示的定时提前调整值，确定PUSCH的定时提前。
N TA_PUSCH＝N TA_associatedSRS+(T A-k)·16·64/2 μ，
其中，k的取值如前所述，N TA_associatedSRS表示的是关联导频SRS的发送定时提前，N TA_PUSCH表示PUSCH的定时提前，T A表示调整值。
同样，上述T A表示的调整值仅是举例说明，本公开的一些实施例中，网络侧设备配置的调整值也可以是(T A-k)·16·64/2 μ，另外，上述公式中的 (T A-k)·16·64/2 μ可以参见上述实施方式的相应说明，此处不作赘述。
可能的方案一：DCI中只有一个TA字段，即该TA字段指示的N TA对所有的传输块(transmission block)都是相同的
可能的方案二：DCI中每个传输块(transmission block)有一个TA字段，即每个传输块(transmission block)的N TA是不同的，这是因为对于多天线组同时传输，每个天线组可能采用不同的传输块(transmission block)传输，则每个传输块的定时提前是不同的。
对于PUCCH，由于终端可以判断PUCCH的发送是否与PUSCH采用相同的发送天线组，如果相同，则采用与PUSCH相同的定时提前，否则，PUCCH的定时提前不变。
本公开的一些实施例可以实现：
当终端存在多个天线组时，不同的天线组对应的定时提前不同，可以给每个上行信号指示不同的定时提前，具体如下：
网络为终端配置不同的定时提前子组，通过MAC CE指示每个定时提前子组的定时提前，终端通过MAC CE确定每个定时提前子组的定时提前；
网络为PUSCH、PUCCH配置定时提前子组ID，终端根据定时提前子组ID，确定PUSCH、PUCCH发送的定时提前；
网络通过MAC CE配置不同的SRS resource set的定时提前，终端根据SRS resource set ID确定PUSCH，PUCCH的发送定时提前；
网络通过DCI指示PUSCH的定时提前。
本公开的一些实施例可以支持对于多天线组多定时提前的指示，提高数据接收质量。
