为了便于理解，先对本申请实施例涉及的一些相关技术知识进行介绍。以下相关技术作为可选方案与本申请实施例的技术方案可以进行任意结合，其均属于本申请实施例的保护范围。本申请实施例包括以下内容中的至少部分内容。
定时提前(Timing Advance，TA)
TA通常用于上行传输，可以指终端设备发送上行数据的系统帧相比对应的下行帧要提前一定的时间。例如，终端设备的定时提前是以终端设备收到下行信道或信道所在的时隙的第一个符号为下行参考，在此基础上进行提前发射。
以载波聚合场景为例，终端设备可以支持不同的载波(又称“服务小区”)。不同的载波可以具有不同的TA，因此，引入了定时提前组(timing advance group，TAG)的概念。通常，一个TAG可以包括的一个或多个服务小区的TA。对于包含特殊小区(special cell，Spcell)的TAG可以称为主定时提前 组(primary timing advance group，PTAG)，相应地，除了PTAG之外的其他TAG可以称为辅定时提前组(secondary timing advance group，STAG)。其中，Spcell可以包括主小区(primary cell，PCell)或主辅小区(primary secondary cell，PSCell)。
当前的通信标准中(包括NR、3GPP Rel.17等)规定，在一个小区组(cell group，CG)中，终端设备可以被配置最多4个定时提前(timing advance group，TAG)。用于配置TAG的RRC配置(用“TAG-Config”表示)可以表示为：
Figure PCTCN2022098258-appb-000001
一般，RRC配置可以包括TAG配置(用“TAG-Config”表示)、TAG信息(用“TAG”表示)、TAG的标识(用“TAG-Id”表示)以及TA定时器(用“timeAlignmentTimer”表示)。其中，TAG配置可以包括释放列表(用“tag-ToReleaseList”表示)以及TAG添加列表(用“tag-ToAddModList”表示)。TAG信息可以包括TAG的标识(用“tag-Id”表示)以及TA定时器(用“timeAlignmentTimer”表示)。TA定时器对应的时长可以以列举的方式列出，包括{500ms,750ms,1280ms,1920ms,2560ms,5120ms,10240ms,无穷}。
通常，TA的有效性可以通过TA定时器来维护，也就是说，当终端设备收到网络设备发送的指示TA的信息(例如，下文的TA命令(TA command，TAC))后，终端设备可以启动或者重启TA定时器。当TA定时器未超时，则TA定时器维护的TA有效，终端设备可以基于TA与网络设备进行通信。相反地，当TA定时器超时，则TA定时器维护的TA失效(或者说无效)，此时，终端设备不能再基于TA与网络设备进行通信。
需要说明的是，一个CG可以包括多个服务小区，且每一个服务小区都会被分配一个TAG的标识。
如上文介绍，TAG信息中可以包含TAG的标识以及TA定时器，也就是说，TAG配置中包括的TA定时器用于维护上述TAG的标识指示的TAG中的TA的有效性。此时，为了便于描述，下文可以称该TA定时器与TAG关联。
下文介绍TA的计算方式。
在一些实现方式中，TA可以通过公式(N TA+N TA，offset)×T c计算，其中，N TA，offset表示定时提前偏移(TA offset)，N TA表示TA调整量，T c表示通信系统(例如，NR系统)中最小时间单位，通常，T c＝1/(4096×480kHz)。
通常，在一个CG中，每一个服务小区都可以预先配置一个N TA，offset。另外，N TA可以由网络设备的MAC CE来提供差分式的调整，即本次TA调整(又称“new TA”，表示为
Figure PCTCN2022098258-appb-000002
)是以上次TA(又称“old TA”，表示为
Figure PCTCN2022098258-appb-000003
)为基础，在时间上向前或向后调整的。调整的计算公式如下：
Figure PCTCN2022098258-appb-000004
或者说，
Figure PCTCN2022098258-appb-000005
是收到TA命令(TA command，TAC)之前使用的TA调整量，
Figure PCTCN2022098258-appb-000006
是收到TAC后更新后的TA调整量。其中，T A是根据TAC确定的。另外，该TA调整的粒度可以为TAG。
图2示出了承载TAC的MAC CE的格式。参见图2，MAC CE可以包括TAG的标识(TAG ID)字段以及TAC字段。通常，TAG ID字段长度可以为2比特，并且包含SpCell的TAG具有TAG的标 识为0。TAC字段用于指示TA索引值TA(0,1,2…63)，用于控制MAC实体必须应用的定时调整量(如TS 38.213[6]中规定的)。该字段的长度可以为6比特。
在另一些实现方式中，TA调整方式可以是以TA的绝对值(又称“绝对TA”)为基础调整，即不需要考虑之前的TA调整值，网络设备可以通过绝对MAC CE(Absolute MAC CE)或RAR MAC的载荷(payload)直接给出一个绝对TA用“N` TA”表示。通常，绝对TA的取值范围可以是0到3846，相应地，TA可以通过公式：N` TA＝T A×16×64×2 μ计算，其中，T A是根据TAC确定的。
在一些场景中，上述绝对TA以及T A的获取方式发生在随机接入过程中，所获取的TA适用于随机接入的目标小区对应的TAG，因此，承载TAC的信令可以不包含TAG-ID。例如，绝对MAC CE可以用于两步随机接入过程，且两步随机接入只能向SpCell发起，因此，绝对MAC CE适用于该MAC实体所对应的PTAG，即该PTAG包含SpCell。
图3示出了承载TAC的MAC CE的格式。参见图3，MAC CE的长度可以为2字节，即16比特。MAC CE可以包括TAC字段，TAC字段可以占用12比特。该字段用于指示MAC实体应用的时间调整量的TA索引值。另外，MAC CE中剩余的4比特可以作为保留位(用“R”表示)，可以置0。
图4示出了承载TAC的MAC随机接入响应(random access response RAR)的格式。参见图4，MAC RAR的长度可以为7字节，即56比特。在第一字节(用“Oct 1”表示)中，可以包括TAC字段，TAC字段可以占用7比特。该字段用于指示MAC实体应用的时间调整量的TA索引值。Oct 1中剩余的1比特可以作为保留位(用“R”表示)，可以置0。
在第二字节(用“Oct 2”表示)中，可以继续包括TAC字段，TAC字段可以占用5比特。Oct 2中剩余的3比特可以承载上行授权(UL Grant)。
在第三字节到第五字节(用“Oct 3～5”表示)中，可以继续承载上行授权(UL Grant)。在第六字节到第七字节(用“Oct 6～7”表示)中，可以继续承载临时小区无线网络临时标识(cell-radio network temporary identifier，C-RNTI)。
多TRP(multi-TRP，mTRP)场景的调度
参见图5，在多DCT-多TRP(Multiple DCI-Multiple TRP，mDCI-mTRP)的场景下，每个TRP可以通过各自的DCI来调度其PDSCH传输。即，TRP1可以通过物理下行控制信道(physical downlink control channel，PDCCH)1承载的下行控制信息(downlink control information，DCI)调度物理下行共享信道(physical downlink shared channel，PDSCH)1的传输，TRP2可以通过PDCCH2承载的DCI调度PDSCH2的传输。
申请人认为，在后续协议的演进过程中，每个TRP也可能调度各自的PUSCH传输。继续参见图5，即TRP1可以通过PDCCH1承载的DCI调度PUSCH1的传输，TRP2可以通过PDCCH2承载的DCI调度PUSCH2的传输。
需要说明的是，mDCI-mTRP的场景中，对于DCI的需求量较大且各个TRP进行独立的调度，因此增加了DCI所在的占用控制资源集合(control resource set，CORESET)的数量。在一些实现方式中，可以将CORESET通过它对应的RRC参数“控制资源集合池索引(CORESETPoolIndex)”进行分组，即CORESETPoolIndex为“0”的控制资源集合可以分为一组，对应TRP1。CORESETPoolIndex为“1”的控制资源集合可以分为一组，对应TRP2。另外，当网络设备没有为控制资源集合配置CORESETPoolIndex的时候，可以默认CORESETPoolIndex为“0”。
另外，如果终端设备工作在一个TRP(sTRP)的模式下，那么终端设备的定时提前的参考点是以下行接收时间点算起。在mTRP的场景下，终端设备仍可以使用两个TRP中的一个作为下行接收的参考点来调整TA。比如使用CORESETPoolIndex为0的TRP作为下行接收的参考点。或者网络设备可以配置的某一个特定的TRP作为下行接收的参考点。这种，基于单一下行参考点的前提可以是终端设备仅有一套下行的接收时间线，即取决于终端设备的能力。
当然，对于能力较强的终端设备来说，也可以使用两个不同的下行接收参考点。继续参见图5，两个TRP可以对应不同下行参考点，那么网络设备指示的两个TA值则是根据各自的参考点来进行调整。
上行多TRP操作
在目前通信协议(例如，3GPP Rel.17)中，支持了基于多TRP的上行PUCCH/PUSCH的重复(repetition)传输，其目的是增强上行的覆盖和传输的可靠性。终端设备需要向不同的TRP发送承载相同内容的物理上行控制信道(physical uplink control channel，PUCCH)/物理上行共享信道(physical uplink shared channel，PUSCH)。对于PUSCH的重复传输而言，目前的标准中仅支持基于sDCI的PUSCH重复传输，使用一个定时提前的TA来顺序发送PUSCH到不同的TRP。对于基于mDCI的PUSCH重复传输，由于多个TRP之间可能没有足够理想的回程线路(backhaul)作为连接，多个TRP 对终端设备的独立调度有可能引起不同PUSCH/PUCCH在时间上的重叠。
对sDCI的mPUSCH传输，可以在上行调度DCI中使用信道探测参考信号资源集指示(sounding reference signal resource set indicator)域，并通过SRS资源集指示域指示1个或2个SRS资源集，它指向对1个或2个TRP的传输，且可以动态地调整sTRP或mTRP的上行传输。
目前，可以使用第一SRS资源集(1st SRS resource set)和第二SRS资源集(2nd SRS resource set)来分别表征第一TRP和第二TRP。因此，在本申请实施例中，TRP的标识也可以基于SRS资源集标识确定。例如，TRP的标识可以为SRS资源集标识。
另外，对于上行的信道和信号的定时提前来说，PUSCH/PUCCH/SRS(不管是朝向一个TRP发射，还是对准两个TRP发射)都可以使用同一个TA值。
如上文所述，传统的TA是以TAG为粒度进行定时提前的调整的，并且一个TAG对应一个服务小区。这种以服务小区为粒度配置TA的方式可能过于粗糙，导致终端设备基于TRP所属服务小区对应的TA与TRP通信时，可能依然会产生干扰。
例如，若一个服务小区包括多个TRP时，不同的TRP可能与终端设备之间的距离不同，此时，如果终端设备依然基于服务小区对应的TA向服务小区内的多个TRP发送上行信号，这可能导致上行信号到达TRP之后依然存在干扰。
因此，为了避免上述问题，本申请实施例提供一种无线通信方法，以TRP为粒度指示TA，有助于降低终端设备与TRP进行通信时产生的干扰。下文结合图6介绍本申请实施例的通信方法。图6所示的方法包括步骤S610。
在步骤S610中，网络设备向终端设备发送第一信息。
上述第一信息用于指示一个或多个TRP的TA。其中，一个或多个TRP对应的TA可以是上文介绍的TA的调整量，当然，上述一个或多个TRP对应的TA也可以是TA的具体值，本申请实施例对此不作限定。另外，若上述TA为TA调整值时，基于TA调整值确定TA的方式可以参见上文的介绍，为了简洁，在此不再赘述。
在一些实现方式中，上述第一信息可以承载于MAC协议数据单元(protocol data unit，PDU)，
(例如，MAC CE、MAC RAR等等)或DCI中。当然，在本申请实施例中，上述第一信息还可以承载于其他信令或消息，本申请实施例对此不作限定。
下文结合实施例1和实施例2，介绍本申请实施例中一个或多个TRP的TA的指示方式。
实施例1
在本申请实施例中，可以沿用基于TAG的TA指示方式，来指示一个或多个TRP的TA。即第一信息包含第一TAG的TA，第一TAG与一个或多个TRP关联。
在本申请实施例中，沿用传统的基于TAG的TA指示方式，指示一个或多个TRP的TA。此时，TAG不再与服务小区关联，而是与TRP关联。这种沿用传统的TA指示方式有助于提高与现有协议的兼容性。
在一些场景中，终端设备的有些服务小区可能未配置mTRP，另外的服务小区可能配置了mTRP，此时，上述第一TAG可以关联一个或多个TRP，并且，第一TAG还可以关联一个或多个服务小区。其中，第一TAG关联的服务小区可以是未配置mTRP的服务小区。当然，在另一些场景中，上述第一TAG可以仅关联一个或多个TRP。本申请实施例对此不作限定。
如上文所述，基于TAG的TA指示方式中，TAG可以与TRP关联，因此，终端设备还需要获知TAG与TRP之间的关联关系。在一种可能的实现方式中，TAG与TRP之间的关联关系可以通过网络设备的配置信息确定，例如，第一TAG与一个或多个TRP之间的关联关系基于网络设备的配置信息确定。其中，网络设备的配置信息例如可以是RRC配置。
需要说明的是，上述关联关系基于配置信息确定可以包括，配置信息可以直接配置上述关联关系。当然，关联关系基于配置信息确定还可以包括，配置信息可以间接配置上述关联关系。例如，配置信息可以仅配置TAG的个数，不同的TAG与TRP之间的关联关系可以通过其他方式(例如，默认的方式)确定，其中，默认的方式例如可以包括通过协议预先约定，或者，当终端设备出厂时内置内在终端设备中。本申请实施例对此不作限定。
在一些实现方式中，上述网络设备的配置信息可以为终端设备的服务小区的配置信息，其中，终端设备的每个服务小区的配置信息可以包括多个TAG的标识(表示为“tag-ID”)，且多个TAG的标识可以分别关联多个TRP。当然，在另一些实现方式中，上述网络设备的配置信息可以是单独的配置信息，并不包含在服务小区的配置信息中，本申请实施例对此不作限定。
需要说明的是，上述多个TAG的标识可以分别关联多个TRP，可以包括多个TAG的标识中不同的TAG的标识关联多个TRP中不同的TRP，或者说，多个TAG的标识与多个TRP一一对应。当然， 上述多个TAG的标识与多个TRP之间的关联关系还可以是一对多的关联关系或者多对一的关联关系，本申请实施例对此不作限定。
下文以分别结合实现方式1～实现方式3为例，介绍本申请实施例中基于配置信息确定TAG与TRP之间的关联关系的方案。
在实现方式1中，每个服务小区配置中可以包括tag-ID的个数，并且tag-ID与TRP之间的关联关系可以默认的关联关系。假设服务小区配置中tag-ID的个数为2，则tag-ID与TRP之间默认的关联关系包括：tag-ID关联coresetPoolIndex＝0对应的TRP，tag-ID-r18关联coresetPoolIndex＝1对应的TRP。
其中，服务小区配置对应的伪代码可以如下所示。其中，“TAG-Id”分别表示对应的tag-ID的标识。
tag-ID                             TAG-Id,
tag-ID-r18                               TAG-Id,         OPTIONAL，Need S
需要说明的是，可以通过配置“tag-ID-r18”是否为缺省，来指示服务小区中TRP关联的TA。即在服务小区配置对应的服务小区内包括多个TRP(例如2个TRP)的情况下，如果“tag-ID-r18”缺省，则可以表示服务小区内的多个TRP共用相同的TAG-ID，此时，服务小区内的多个TRP对应的TA相同。相反地，如果“tag-ID-r18”不为缺省，则可以表示服务小区内的多个TRP对应的TA是基于各自关联的TAG-ID确定的，此时，服务小区内的多个TRP对应的TA可以不相同。
另外，还可以通过指示“tag-ID-r18”是否有效，来指示服务小区中TRP关联的TA。即在服务小区配置对应的服务小区内包括多个TRP(例如2个TRP)的情况下，且TAG的标识“tag-ID-r18”可以不为缺省，此时，“tag-ID-r18”仅在配置了多TRP对应多个TA(表示为“mTRP-mTA”)的功能时有效，则可以表示服务小区内TRP对应的TA是基于各自关联的TAG-ID确定的，服务小区内的多个TRP对应的TA可以不相同。相反地，若没有配置mTRP-mTA的功能，此时，“tag-ID-r18”无效，则可以表示服务小区内的多个TRP共用相同的TAG-ID，此时，服务小区内的多个TRP对应的TA相同。
在实现方式2中，可以针对每个服务小区配置tag-ID列表，tag-ID列表包括tag-ID与服务小区内TRP之间的关联关系。
tag-ID列表(表示为“tag-IDList”)对应的伪代码可以如下所示。其中，tag-ID列表包括TRP-TA配置(表示为“TRP-TA-config”)，以及TRP-TA配置的最大个数(表示为“maxNrofTRP-TA-config”)。并且TRP-TA配置中包含tag-Id与TRP之间的关联关系，在下文所示的伪代码中，上述关联关系包括TAG-Id关联coresetPoolIndex-r16对应的TRP。
Figure PCTCN2022098258-appb-000007
在实现方式3中，可以引入中间变量，来表示TAG-Id与TRP之间的关联关系。
其中，中间变量可以表示为“mTRP-TA-Id”，并可以分别添加在“tag-TRP”配置信息以及“TRP-TA”配置信息中，“tag-TRP”配置信息还可以包括TAG-Id表示为“tag-Id”，“TRP-TA”配置信息还可以包括coresetPoolIndex-r16，如此，便通过中间变量建立了标识为“TAG-Id”的TAG与coresetPoolIndex-r16对应的TRP之间的关联关系。
Figure PCTCN2022098258-appb-000008
当然，在本申请实施例中，中间变量“mTRP-TA-Id”在“tag-TRP”配置信息中还可以以其他方式添加，具体可以参见下文所示的伪代码。即将中间变量“mTRP-TA-Id”可以通过关联到TRP参数(表示为“LinkingtoTRP”)的方式添加在“tag-TRP”配置信息中。另外，中间变量在“TRP-TA”配置信息中的添加方式与上文介绍相似，为了简洁，在此不再赘述。
Figure PCTCN2022098258-appb-000009
Figure PCTCN2022098258-appb-000010
如上文所述，在本申请实施例中可以沿用基于TAG指示TA的方式，因此，在为终端设备配置TA时，还可以指示TA对应的TAG，即上述第一信息还可以包含用于指示第一TAG的标识的第二信息。
在一些实现方式中，第二信息可以为第一TAG的标识。在另一些实现方式中，第二信息用于指示第一TAG的标识的位图信息，或者说，第一TAG的标识的位图信息用于指示第一信息中是否携带第一TAG的TA。例如，可以通过位图中的每个比特位对应不同的TAG，这样，当比特位为第一值时，可以指示该比特位对应的TAG关联的一个或多个TRP的TA携带在第一信息中，和/或，指示该比特位对应的TAG关联的服务小区的TA携带在第一信息中。相反地，当比特位为第二值时，可以指示该比特位对应的TAG关联服务小区和/或TRP的TA未携带在第一信息中，第一值与第二值不同。
为了便于理解，下文结合图7-8以MAC CE承载上述第一信息为例，介绍本申请实施例适用的承载方式1～2。需要说明的是，本申请实施例的承载方式并不限于此，并且，第一信息中各种信息所占用的比特位也并不限于下文的介绍，例如，TAG的标识占用的比特数量可以是3bit或4bit等。
承载方式1，可以在MAC CE中携带TAG的标识。
参见图7，假设MAC CE包括N个字节，每个字节可以包括8比特，其中N为正整数。每个字节中的两比特可以用于承载TAG的标识，每个字节中的剩余6比特可以承载TA命令，以指示TAG的标识对应的TA。通常，2比特的TAG的标识，可以用于标识4个TAG。
需要说明的是，上述表示TAG的标识的2比特可以是1个字节中的前2比特，也可以是1个字节中的后2比特，本申请实施例对此不作限定。另外，MAC CE包括N个字节中每个字节可以用于指示TAG的标识及其对应的TA，具体的承载方式与上文介绍相似，为了简洁，在此不再赘述。
在本申请实施例中，可以沿用传统的指示TAG的标识及其对应的TA的方式(例如，参见图所示的命令格式)，以提高与现有协议的兼容性。
承载方式2，可以在MAC CE中携带指示TAG的标识的位图信息。
参见图8，假设MAC CE包括N个字节，每个字节可以包括8比特，其中N为大于1的正整数。第N个字节中的6比特可以承载TA命令以指示TA，另外两个比特可以作为保留位(reserve，用“R”表示)。在第N-1个字节中，可以占用4比特承载TAG的标识的位图信息(用“T”表示)，剩余4比特可以作为保留位(用“R”表示)。在承载位图信息的4个比特中，每个比特可以对应一个TAG的标识，当4个比特中的某一比特值取为第一值(例如“1”)，可以表示对应的TAG的标识与TA对应，或者说，TAG的标识指示的TAG的TA携带在MAC CE中。当4个比特中的某一比特值取为第二值(例如“0”)，可以表示对应的TAG的标识与TA不对应，或者说，TAG的标识指示的TAG的TA未携带在MAC CE中。其中，TAG的TA可以包括TAG关联的一个或多个TRP的TA，和/或，TAG关联的一个或多个服务小区的TA，并且第一值与第二值不同。
需要说明的是，上述用于承载TAG的标识的位图信息，可以基于TAG的标识的数量确定。例如，假设需要指示8个TAG关联的TA，那么MAC CE中可以占用8比特承载TAG的标识的位图信息。本申请实施例对MAC CE中位图信息占用的比特位的数量不作限定。
在本申请实施例中，可以通过一条信令中的位图信息表示多个TA与多个TAG的标识之间的对应关系，有助于减少传输指示TAG的标识所需的开销。
另外，在本申请实施例中，可以通过一条信令携带较多的TAG的标识，有利于提高指示与TA对应的TAG的标识的灵活性。在一些情况下，还可以占用保留位来承载TAG的标识的位图信息，以进一步扩充携带的TAG的标识的个数。
实施例2
在本申请实施例中，可以直接通过第一信息指示TRP的TA。即第一信息包含第一TRP的TA，或者说，第一信息包含第一TRP，以及与第一TRP对应的TA。
在一些实现方式中，上述第一TRP可以通过第一TRP所属的小区的小区标识和/或第一TRP标识的方式来标识，也就是说，上述第一信息还可以包括第三信息和/或第四信息，其中，第三信息用于指示第一TRP所属的小区的小区标识，第四信息用于指示第一TRP的标识，其中第四信息例如可以是“CORSETPollIndex”。当然，在本申请实施例中，也可以通过其他信息来标识TRP，例如，参考信号集合(例如，SRS资源集合)或者TRP索引，本申请实施例对此不作限定。
在另一些实现方式中，上述第三信息可以为第一TRP所属的小区的小区标识。或者，上述第三信 息可以用于指示第一TRP所属的小区的小区标识的位图信息，其中，位图信息用于指示比特位对应的小区内的TRP的TA是否携带在第一信息中。例如，可以通过位图中的每个比特位对应不同的小区，这样，当比特位为第一值时，可以指示第一信息携带了该小区的TA或者指示该小区配置的至少一个TRP的TA，相反地，当比特位为第二值时，可以表示该小区的TA，以及该小区配置的至少一个TRP的TA未携带在第一信息中，其中，第一值与第二值不同。
为了便于理解，下文结合图9-图10以MAC CE承载上述第一信息为例，介绍本申请实施例适用的承载方式3～4。需要说明的是，本申请实施例的承载方式并不限于此。
承载方式3，可以在MAC CE中携带第一TRP所属小区的小区标识，第一TRP的标识以及第一TRP的TA。
参见图9，假设MAC CE包括2个字节，每个字节可以包括8比特。在第一个字节(用“Oct 1”表示)中，第一TRP所属小区的小区标识可以占用5比特，并且，第一个字节中的剩余比特可以作为保留位(用“R”表示)。在第二个字节(用“Oct 2”表示)中，指示TA的TA命令可以占用6比特，并且，第一TRP的标识“CORSETPollIndex”可以占用1比特，剩余的1比特可以作为保留位。
需要说明的是，如果需要通过一条MAC CE指示多个TRP对应的TA，可以在MAC CE包含多个字节，其中，多个字节中的每两个字节可以用于指示一个TRP对应的TA，如图10所示，其信息的承载方式可以与上文Oct 1、Oct 2中信息的承载方式相同，具体可以参见上文所述，为了简洁，在此不再赘述。
在本申请实施例中，可以通过一条信令中的多个字节表示多个TRP对应的TA，有助于减少传输指示多个TRP对应的TA的信息所需的开销。
承载方式4，可以在MAC CE中携带指示第一TRP所属小区的位图信息，第一TRP的标识以及第一TRP的TA。
参见图11，假设MAC CE包括N个字节，每个字节可以包括8比特，其中N为大于1的正整数。在第N个字节中，指示TA的TA命令可以占用6比特，并且，第一TRP的标识“CORSETPollIndex”可以占用1比特，剩余的1个比特可以用于指示对应服务小区是否配置了mTRP(用“mTRP”表示)。通常，mTRP指示对应服务小区配置了mTRP时，说明服务小区中包含多个TRP，此时，上述MAC CE中可以携带一条或多条TA命令，以指示多个TRP的TA。相反地，mTRP指示对应服务小区未配置mTRP时，说明服务小区中包含1个TRP，或者说该服务小区未配置mTRP，此时，上述TA命令中可以携带一个TA，以指示该服务小区的TA。
在第N-1个字节(例如，第一个字节)中，可以占用8比特承载第一TRP所属小区的位图信息(用“C”表示)。8个比特中每个比特可以对应一个小区，当8个比特中的某一比特值取为第一值(例如“1”)，可以表示该MAC CE携带了该小区的TA信息，其中，该小区的TA信息可以包括该小区的TA和/或该小区的TRP的TA。当8个比特中的某一比特值取为第二值(例如“0”)，可以表示该MAC CE未携带该小区的TA信息，其中，第一值与第二值不同。
需要说明的是，上述位图信息可以占用8比特(即4个字节)来指示的小区。此时，8比特的位图信息最多可以对应32个小区。
在一些实现方式中，上述位图信息对应的小区可以包括终端设备的部分或全部服务小区。其中，部分服务小区例如可以包括终端设备的前8个服务小区。全部服务小区例如可以包括终端设备的32个服务小区(此时，可以位图信息可以占用4字节)。当然，上述位图信息对应的小区还可以包括配置了mTRP的服务小区。本申请实施例对此不作限定。
在另一些实现方式中，上述位图信息对应的小区可以按照小区索引的升序或者降序来排序，例如，参见11所示，承载位图信息的8比特可以对应8个小区，那么，按照比特位递增的顺序，对应的8个小区的索引也可以以递增的方式排序。即，比特0可以对应小区索引0，比特1可以对应小区索引1，……，比特8可以对应小区索引8。当然，按照比特位递增的顺序，对应的8个小区的索引可以以递减的方式排序。即，比特0可以对应小区索引8，比特1可以对应小区索引7，……，比特8可以对应小区索引0。通常，主小区的索引可以对应上述8比特中的第一个比特，或者主小区的索引可以对应上述8比特中的最后一个比特。
在本申请实施例中，可以以位图信息的方式指示TRP所属的小区，有助于减少第一信息中承载指示TRP所属的小区占用的比特位的数量，以减少传输TRP所属的小区的指示信息所需的开销。
上文结合图9～图11介绍了通过第一信息指示第一TRP的方式。在本申请实施例中，可以通过其他方式指示第一TRP。
在一些实现方式中，上述第一信息可以承载于RAR中，相应地，终端设备可以基于RAR确定第一TRP的TA。下文结合图12和图13介绍通过RAR指示第一TRP的TA的方案。
参见图4所示，传统的RAR中指示的TA值是基于每个服务小区指示的，并且，图4所述所示的RAR格式包含1比特的保留位。因此，在本申请实施例中，可以沿用图4所示的RAR格式，并在RAR中携带第一TRP的标识。其中，第一TRP的标识可以占用图4中的保留位，参见图12所示。
参见图3所示，传统的MAC CE格式中包括4比特的保留位，因此，在本申请实施例中，可以沿用图3所示的MAC CE格式，并占用其中的保留位来携带第一TRP的标识。参见图13所示，可以占用4比特的保留位中的某1比特来传输携带第一TRP的标识。
在另一些实现方式中，上述第一信息包括终端设备在随机接入过程中接收到的信息，第一TRP可以是基于以下中的一种或多种确定的：用于随机接入过程的资源，其中，不同的资源可以对应不同的TRP；用于随机接入过程的资源的资源指示信息，其中，资源的资源指示信息包含指示第一TRP的标识的信息；第一上行数据所发往的TRP，其中，随机接入过程是由第一上行数据到达、但终端设备处于上行失步状态而触发的；以及随机接入过程的触发方式(或者称为“触发类型”)，其中，随机接入过程的触发方式可以包括多个触发方式，随机接入过程对应的小区包括多个TRP，多个触发方式与多个TRP一一对应，或者说，不同的触发方式对应不同的TRP。
在一些场景中，对于终端设备发起的随机接入过程，网络设备可以配置多个TRP中的每个TRP对应一个用于随机接入的资源，不同的TRP对应的用于随机接入的资源可以不同。如此，终端设备可以选择第一TRP对应的资源发起随机接入，相应地，网络设备可以基于随机接入占用的资源来确定第一TRP。
需要说明的是，上述用于随机接入的资源可以是在4步随机接入过程中，传输消息1(msg1，或者称“前导码”)所占用的资源。当然，上述用于随机接入的资源还可以是在2步随机接入过程中，传输消息A(msgA)所占用的资源。其中，资源可以是时域资源、频域资源或码域资源中的一种或多种。例如，可以通过前导码(preamble)来区分不同的TRP，或者，可以通过不同的随机接入信道机会(random access channel occasion，RO)来区分不同的TRP。
在另一些场景中，对于网络设备发起的随机接入过程，网络设备可以在用于随机接入的资源的资源指示信息中携带第一TRP的标识。相应地，终端设备可以基于资源指示信息确定第一TRP。也就是说，对于网络设备触发的随机接入过程，网络设备可以向终端设备发送触发指示，以触发终端设备的随机接入过程，其中，触发指示中可以携带资源指示信息，并指示第一TRP。
在另一些场景中，随机接入过程可以是由第一上行数据到达、但终端设备处于上行失步状态而触发的。终端设备可以基于第一上行数据所属的逻辑信道或逻辑信道组，判断第一上行数据所发往的TRP。也就是说，第一TRP可以基于第一上行数据所发往的TRP确定。
在另一些场景中，多个TRP可能与随机接入过程的多个触发方式一一对应，因此，终端设备可以基于随机接入过程的触发方式，确定第一TRP。在一些实现方式中，多个触发方式可以包括通过MAC层流程触发所述随机接入过程；和/或通过物理层流程触发所述随机接入过程。
其中，通过MAC层流程触发所述随机接入过程，可以理解为由MAC实体所触发的随机接入过程，例如，竞争的随机接入(contention based random access，CBRA)。通过物理层流程触发所述随机接入过程，可以理解为基于PDCCH命令触发的随机接入过程。
例如，每个服务小区包括的TRP可以区分为主TRP和辅TRP。对于主TRP而言，终端设备可以发起CBRA。对于辅TRP而言，终端设备可以基于PDCCH命令来触发随机接入流程。也即是说，服务小区中的主TRP和辅TRP可以对应不同的随机接入过程的触发方式，因此，可以基于随机接入过程的触发方式，确定第一TRP。
又例如，除了主小区的主TRP外，其余的SCell或PCell中的TRP都为辅TRP。对于主小区的主TRP而言，终端设备可以发起CBRA。对于其余的辅TRP而言，终端设需要基于PDCCH命令去触发随机接入过程。此时，终端设备在收到RAR后，可以确定第一TRP。
需要说明的是，上述主TRP、辅TRP可以由网络设备配置，或者，也可以通过默认规则来区分主TRP和辅TRP，例如，coresetpool 1可以对应主TRP，coresetpool 2可以对应辅TRP。本申请实施例对此不作限定。
在本申请实施例中，通过上述确定第一TRP的方式，有助于减少网络设备指示第一TRP所占用的开销。
需要说明的是，上文介绍的TA可能是TA调整值或者绝对TA，绝对TA可以是N TA值，本申请实施例对此不作限定。在本申请实施例中，TA调整值的指示方式可以与绝对TA的指示方式结合使用。例如，当上文结合图7至图11介绍的指示方式中TA为TA调整值，上文结合图12至图13介绍的指示方式中TA为绝对TA时，图7至图11介绍的任一种指示方式，可以与图12至图13介绍的任一种指示方式结合使用，来为终端设备配置TA。其中，TA调整值和绝对TA的用法在上文介绍TA时已 详细介绍，为了简洁，在此不再赘述。
目前，TA的有效性通常是通过TA定时器(又称“第一定时器”)来维护的，当TA定时器超时后，对应的TA失效(或者说无效)，此时，终端设备无法再基于无效的TA与对应的TRP通信。相反地，当TA定时器未超时，对应的TA有效，此时，终端设备可以基于有效的TA与对应的TRP通信。在本申请实施例的方案中，以TRP为粒度配置TA后，为了减少TA对应的TA定时器的数量，可以使用一个TA定时器对应多个TRP的TA。当然，如果不考虑TA定时器的数量的问题，可以为每个TRP的TA配置一个定时器。
也即是说，上述方法还包括：终端设备根据第一信息启动或重启第一定时器，第一定时器用于维护一个或多个TRP的TA的有效性。在一些实现方式中，可以将服务小区内多个TRP的TA划分为一个或多个组，每个组包含一个或多个TA，并且，每个组内的TA可以对应一个定时器。
需要说明的是，上述终端设备根据第一信息启动或者重启第一定时器，可以包括，终端设备收到第一信息时，启动或重启第一定时器。或者说，终端设备接收第一信息可以作为启动或重启第一定时器的触发条件。相应地，在终端设备接收到第一信息后，可以应用第一信息中指示的TA。
需要说明的是，若通过TAG指示TRP的TA(例如，实施例1中介绍的方案)，则上述第一定时器可以与一个或多个TAG关联。若直接指示TRP的TA(例如，实施例2中介绍的方案)第一定时器可以与一个或多个TRP关联。
为了便于理解，下文结合图14介绍本申请实施例中TA与定时器之间的关联关系。参见图14，假设终端设备的服务小区包括服务小区1、服务小区2以及服务小区3，并且上述3个服务小区配置了mTRP。其中，服务小区1中包括的TRP为TRP1和TRP2，服务小区2中包括的TRP为TRP1和TRP2，服务小区3中包括的TRP为TRP1和TRP2。
相应地，服务小区1的TRP1的TA1关联TAG1。服务小区1的TRP2的TA2可以与服务小区2的TRP1的TA2关联TAG2。服务小区2的TRP2的TA3可以与服务小区3的全部TRP的TA3关联TAG3。
作为一个示例，可以为每个服务小区内的TRP配置一个小区组内唯一的ID(例如，mTRP-TA-Id)，并且可以将每个ID关联一个定时器的配置，这样就可以通过建立ID与定时器之间的关联关系，将多个ID关联到同一个定时器配置。相应地，在TA调整的时候，可以用ID来标识。其中，上述ID可以为上文中提及的服务小区标识和coresetpool ID。
相应地，添加了唯一的ID：“mTRP-TA-Id”的TRP-TA信息对应的伪代码可以如下所示。其中，TRP-TA信息指示TA对应的TRP。
Figure PCTCN2022098258-appb-000011
添加了唯一的ID：“mTRP-TA-Id”的TA信息对应的伪代码可以如下所示。其中TA信息还包含TA定时器标识(用“TA-Timer-ID”表示)。另外，该TA定时器标识用于标识TA定时器配置(用“TA-Timer-Config”表示)，其中，TA定时器配置包括TA定时器标识以及TA定时器(用“TimeAlignmentTimer”表示)，并且TA定时器对应的时长可以以列举的方式列出，包括{500ms,750ms,1280ms,1920ms,2560ms,5120ms,10240ms,无穷}。
Figure PCTCN2022098258-appb-000012
在一些实现方式中，如果第一定时器超时，则目标操作被触发。其中，目标操作包括以下操作中的一种或多种：清空混合自动重传请求(hybrid automatic repeat request，HARQ)缓冲器；通知无线资源控制(Radio Resource Control，RRC)释放上行资源(其中，上行资源例如可以包括PUCCH，SRS，小 区组(cell group，CG)，PUSCH以及半静态调度(semi-persistent scheduling，SPS)等)；维护定时提前绝对值；发起随机接入流程；以及通过TA有效的TRP重传HARQ缓冲器中的数据。当然，在另一些实现方式中，如果第一定时器超时，终端设备也可以不执行上述目标操作。
在一些场景中(例如，服务小区配置了mTRP)，当第一定时器超时，则第一定时器对应的TA失效，此时，服务小区中可能还有TRP的TA有效，因此，可以通过TA有效的TRP重传HARQ缓冲器中的数据，这样，当第一定时器失效后，终端设备可以无需发起随机接入流程，而直接通过TA有效的TRP重传HARQ缓冲器中的数据，有助于减少终端设备与TRP通信所需的时延。
在上述类似的场景中，服务小区中的多个TRP可能对应多个TA，当第一定时器超时，则第一定时器对应的TA失效，此时，服务小区中可能还有TRP的TA有效，因此，终端设备可以不执行任何目标操作。
需要说明的是，上述目标操作还可以包括现有协议中规定的一种或多种操作，例如，可以包括以下操作的一种或多种：清除已配置的下行链路分配和上行链路授权；清除用于半静态CSI报告的PUSCH资源；将所有运行的TA定时器视为过期。
在不同的场景中，上述目标操作针对的对象可以不同。在一些实现方式，若基于TAG指示TA的方式中(例如，实施例1的方案)，第一定时器可以关联一个或多个TAG，则目标操作针对以下对象中的一种或多种：终端设备的全部服务小区；一个或多个TAG关联的TRP；以及一个或多个TAG关联的TRP所在的服务小区。
其中，终端设备的全部服务小区可以是终端设备建立连接的全部服务小区，或者说，可以是包括终端设备的服务小区列表中的全部服务小区，或者说，还可以包含与终端设备通信的全部服务小区，本申请实施例对此不作限定。
若上述目标操作针对的对象包括一个或多个TAG关联的TRP，且目标操作可以包括清空上述一个或多个TAG包括的TRP所关联的HARQ缓冲器(buffer)。例如，对于配置了多个TRP的服务小区，在服务小区中每个TRP都可以有一个HARQ实体，并且每个HARQ实体中的HARQ进程可以属于不同TRP的，此时，上述目标操作可以包括清空上述一个或多个TAG包括的TRP所关联的HARQ进程对应的HARQ缓冲器。
又例如，对于配置了多个TRP的服务小区，每个服务小区可以有一个HARQ实体，该HARQ实体中的HARQ进程可以被分为多个组，其中多个组关联多个TRP。此时，上述目标操作可以包括清空一个或多个TAG包括的TRP所关联的组中的HARQ进程对应的HARQ缓冲器。
若上述目标操作针对的对象包括一个或多个TAG关联的TRP，且目标操作包括通知RRC释放上行资源。通常，对于配置了多个TRP的服务小区，该服务小区中的每个TRP可以配置相应的上行资源，因此，上述目标操作可以包括通知RRC释放一个或多个TAG关联的TRP对应的上行资源。
需要说明的是，上文中的TAG可以是主定时提前组(primary timing advance group，PTAG)或辅定时提前组(secondary timing advance group，STAG)，本申请实施例对此不作限定。其中，PTAG可以理解为是包含Spcell(PCell或PSCell)的TAG，相应地，除了PTAG之外的其他TAG都可以是STAG。
在另一些实现方式中，当直接指示TRP的TA(例如，实施例2的方案)，第一定时器可以关联一个或多个TRP，则目标操作针对以下对象中的一种或多种：终端设备的全部服务小区；一个或多个TRP；以及一个或多个TRP所在的服务小区。
当上述目标操作针对的对象包括一个或多个TRP，且目标操作可以包括清空上述一个或多个TRP所关联的HARQ缓冲器(buffer)。例如，对于配置了多个TRP的服务小区，在服务小区中每个TRP都可以有一个HARQ实体，并且每个HARQ实体中的HARQ进程可以属于不同TRP的，此时，上述目标操作可以包括清空上述一个或多个TRP所关联的HARQ进程对应的HARQ缓冲器。
又例如，对于配置了多个TRP的服务小区，每个服务小区可以有一个HARQ实体，该HARQ实体中的HARQ进程可以被分为多个组，其中多个组关联多个TRP。此时，上述目标操作可以包括清空一个或多个TRP所关联的组中的HARQ进程对应的HARQ缓冲器。
若上述目标操作针对的对象包括一个或多个TRP，且目标操作包括通知RRC释放上行资源。通常，对于配置了多个TRP的服务小区，该服务小区中的每个TRP可以配置相应的上行资源，因此，上述目标操作可以包括通知RRC释放一个或多个TRP对应的上行资源。
需要说明的是，上文中的TAG可以是PTAG或STAG，本申请实施例对此不作限定。
如上文所述，在通过TAG指示TA的方案中，TAG可以关联服务小区，也可以关联一个或多个TRP。当TAG关联一个或多个TRP时，终端设备行为(包括执行目标操作以及不执行目标操作)可以参见上文的介绍。当TAG仅关联服务小区时，终端设备可以执行的操作结合下文介绍。
当TAG关联的TA定时器超时后，若该TAG为PTAG，可以对全部服务小区都执行相应的操作。其中，终端设备执行的操作可以包括以下一种或多种：清空全部服务小区的HARQ缓冲器；对于配置了PUCCH的服务小区，通知RRC释放全部上述服务小区的PUCCH；对于配置了SRS的服务小区，通知RRC释放全部上述服务小区的SRS；清除已配置的下行链路分配和上行链路授权；清除用于半持久化CSI报告的PUSCH资源；将所有运行的TA定时器视为过期；以及维护全部TAG的N TA(在TS38.211[8]中定义的参数)。
若上述TAG为STAG，可以对STAG关联的服务小区执行相应的操作。其中，终端设备执行的操作可以包括以下一种或多种：清空HARQ缓冲器；对于配置了PUCCH的服务小区，通知RRC释放PUCCH；对于配置了SRS的服务小区，通知RRC释放SRS；清除已配置的下行链路分配和上行链路授权；清除用于半持久化CSI报告的PUSCH资源；将所运行的TA定时器视为过期；以及维护上述TAG(即STAG)的N TA(在TS 38.211[8]中定义的参数)。需要说明的是，TAG关联的是服务小区还是一个或多个TRP，可以基于小区是否配置mTRP确定。当然，还可以基于其他方式确定，例如，协议预定义或者预先配置等，本申请实施例对此不作限定。
当TAG关联一个或多个TRP的同时还关联了一个或多个服务小区时，终端设备执行的操作，可以根据与TAG关联的是TRP还是服务小区来区分。也就是说，若TAG关联一个或多个TRP的同时还关联了一个或多个服务小区，对于TAG关联的一个或多个TRP，则终端设备执行的操作可以参见上文的介绍。
在一些实现方式中，终端设备还可以基于上述一个或多个TRP所属的服务小区的类型，执行目标操作，其中，服务小区的类型可以与目标操作关联。例如，不同类型的服务小区可以关联不同目标操作，当然，不同类型的服务小区也可以关联相同的目标操作。本申请实施例对此不作具体限定。
上述服务小区的类型可以包括主小区，辅小区，主辅小区等等，本申请实施例对此不作限定。
在另一些实现方式中，终端设备还可以基于上述一个或多个TRP所属的服务小区类型，针对某个对象(又称“目标操作的对象”)执行目标操作()。其中，服务小区的类型可以与目标操作的对象关联。例如，不同类型的服务小区可以关联不同的目标操作的对象。当然，不同类型的服务小区也可以关联相同的目标操作对象，本申请实施例对此不作限定。为了便于理解，下文以服务小区类型包括主小区以及辅小区为例，进行介绍。
当TRP所属的服务小区的类型为主小区时，终端设备执行的目标操作的对象可以为终端设备所有的服务小区。当TRP所属服务小区的类型为辅小区时，终端设备执行的目标操作的对象可以为该TRP。
以TRP所属的服务小区为服务小区2为例，若服务小区2的类型为主小区时，终端设备执行的目标操作的对象可以为所有服务小区或该TRP。若服务小区2的类型为辅小区时，终端设备执行的目标操作的对象可以为该TRP或者服务小区2。
当TAG关联一个或多个TRP的同时还关联了一个或多个服务小区，对于该TAG关联的第一服务小区，则终端设备可以对上述关联的第一服务小区执行相应的操作(又称为第一操作)。其中，终端设备执行的操作可以包括以下一种或多种：清空第一服务小区的HARQ缓冲器；若第一服务小区配置了PUCCH，通知RRC释放第一服务小区的PUCCH；若第一服务小区配置了SRS，通知RRC释放第一服务小区的SRS；清除已配置的下行链路分配和上行链路授权；清除用于半持久化CSI报告的PUSCH资源；将所有运行的TA定时器视为过期；以及维护上述TAG的N TA(在TS 38.211[8]中定义的参数)。
例如，TAG1关联了服务小区2的TRP1和服务小区1，那么，TAG1关联的定时器超时后，对于TRP1，终端设备执行的操作可以参见上文的介绍。对于服务小区1，终端设备可以对服务小区1执行相应的操作。其中，终端设备执行的操作可以包括以下一种或多种：清空服务小区1的HARQ缓冲器；若服务小区1配置了PUCCH，通知RRC释放服务小区1的PUCCH；若服务小区1配置了SRS，通知RRC释放服务小区1的SRS；清除已配置的下行链路分配和上行链路授权；清除用于半持久化CSI报告的PUSCH资源；将所有运行的TA定时器视为过期；以及维护上述TAG的N TA(在TS 38.211[8]中定义的参数)。
在一些实现方式中，终端设备还可以基于第一服务小区的类型，执行第一操作，其中，第一服务小区的类型可以与第一操作关联。例如，不同类型的服务小区可以关联不同第一操作，当然，不同类型的服务小区也可以关联相同的第一操作。本申请实施例对此不作具体限定。
上述服务小区的类型可以包括主小区，辅小区，主辅小区等等，本申请实施例对此不作限定。为了便于理解，下文以服务小区类型包括主小区以及辅小区为例，进行介绍。
在另一些实现方式中，终端设备还可以基于第一服务小区的类型，针对某个对象执行第一操作。其中，服务小区的类型可以与第一操作的对象关联。例如，不同类型的服务小区可以关联不同的对象。当然，不同类型的服务小区也可以关联相同的对象，本申请实施例对此不作限定。为了便于理解，下文 以服务小区类型包括主小区以及辅小区为例，进行介绍。
若服务小区1的类型为主小区，终端设备可以对所有的服务小区执行第一操作。若服务小区1的类型为辅小区，终端设备可以仅对服务小区1执行第一操作。
当TAG关联一个或多个TRP的同时还关联了一个或多个服务小区。对于TAG关联的一个或多个TRP，终端设备还可以基于关联的服务小区是否关联多个TRP(或者说，关联的服务小区是否配置mTRP)和/或服务小区的类型，执行不同的目标操作和/或针对不同的目标操作的对象执行目标操作。当然，在本申请实施例中，终端设备还可以基于该服务小区关联的多个TRP中TA无效的TRP的个数，执行不同的目标操作和/或针对不同的目标操作的对象执行目标操作。例如，若服务小区关联多个TRP，且服务小区的类型为主小区，当每个TRP对应的TAG所关联的定时器均为停止或超时状态时，终端设备可以对所有的服务小区执行目标操作。
又例如，若服务小区关联多个TRP，且服务小区的类型为辅小区，当每个TRP对应的TAG所关联的定时器均为停止或超时状态时，终端设备可以对当前的服务小区执行目标操作。
又例如，若服务小区关联多个TRP，当多个TRP中至少有一个TRP对应的TAG所关联的定时器处于运行状态时，终端设备的目标操作的对象可以只包括上述定时器处于运行状态的TA所属的TRP。应理解，在本申请实施例中，上述服务小区的类型、服务小区是否配置多TRP、以及TA无效的TRP的个数都可以单独作用以确定终端设备执行的操作或者操作的对象。当然，上述三个条件中的部分或全部条件也可以任意组合以确定终端设备执行的操作或者操作的对象，又或者，上述三个条件还可以结合其他条件以确定终端设备执行的操作或者操作的对象。本申请实施例对此不作限定。
另外，在终端设备执行了上述目标操作之后，网络设备也可以执行相应地操作。例如，网络设备可以执行的目标操作也可以包括以下操作中的一种或多种：清空网络设备接收到的通过HARQ缓冲器发送的数据；释放上行资源(其中，上行资源例如可以包括PUCCH，SRS，CG，PUSCH以及SPS等)；维护定时提前绝对值；发起随机接入流程；维护数据，该数据包括通过TA有效的TRP重传HARQ缓冲器中的数据。另外，网络设备执行的目标操作在不同的场景中可以针对不同的对象，具体划分方式，可以参见上述终端设备执行的目标操作在不同的场景中针对的对象，为了简洁，下文不再赘述。当然，在本申请实施例中，网络设备也可以不执行任何目标操作。
为了兼容服务小区未配置mTRP的场景，上文第一信息也可以适用服务小区未配置mTRP的场景。例如，当终端设备的服务小区配置mTRP，第一信息用于指示一个或多个TRP的TA，一个或多个TRP属于配置mTRP的服务小区。相反地，当终端设备的一个或多个服务小区未配置mTRP，第一信息用于指示一个或多个服务小区的TA。当然，在本申请实施例中，上述第一信息也可以仅适用服务小区配置mTRP的场景。
上文结合图1至图14，详细描述了本申请的方法实施例，下面结合图15至图17，详细描述本申请的装置实施例。应理解，方法实施例的描述与装置实施例的描述相互对应，因此，未详细描述的部分可以参见前面方法实施例。
