Description

通信方法和通信装置
本申请要求于2022年06月02日提交中国专利局、申请号为202210626015.3、申请名称为“一种唤醒端设备的方法”的中国专利申请的优先权、以及2022年06月10日提交中国专利局、申请号为202210654913.X、申请名称为“通信方法和通信装置”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及通信领域，并且更具体地，涉及一种通信方法和通信装置。
背景技术
终端设备可以通过一个单独的低功耗小电路，如唤醒无线电(wake up radio，WUR)，接收唤醒信号，且主接收机可以处于睡眠状态。当终端设备通过WUR检测到唤醒信号后，终端设备触发主接收机的唤醒。主接收机唤醒后，终端设备可以通过主接收机接收数据等。
在一些场景下，网络设备可以采用广播或组播的方式发送数据。若终端设备的主接收机处于睡眠状态，则按照现有技术，网络设备要对所有需要接收该数据的终端设备一一发送寻呼，这样，可能会造成比较大的寻呼资源开销。
发明内容
本申请提供一种通信方法和通信装置，能够降低一一寻呼至少两个终端设备带来的资源开销。
第一方面，提供了一种通信方法，该方法可以由终端设备执行，或者，也可以由终端设备的组成部件(例如芯片或者电路)执行，对此不作限定。为了便于描述，下面以由终端设备执行为例进行说明。
该方法可以包括：终端设备接收第一唤醒信号，第一唤醒信号用于唤醒终端设备组，终端设备组包括至少两个终端设备，且至少两个终端设备包括该终端设备；终端设备根据第一唤醒信号接入网络设备。
例如，以终端设备为第一终端设备为例，该方法可以包括：第一终端设备接收第一唤醒信号，第一唤醒信号用于唤醒终端设备组，终端设备组包括至少两个终端设备，且至少两个终端设备包括该第一终端设备；第一终端设备根据第一唤醒信号接入网络设备。
基于上述技术方案，网络设备通过发送唤醒信号唤醒一组终端设备，也即该一组终端设备可以基于相同的唤醒信号接入网络设备。在某些场景下，如网络设备要向一组终端设备发送数据，相比于网络设备向该组终端设备中的各个终端设备一一发送针对各个终端设备的唤醒信号的方案，本申请实施例的方案，发送唤醒信号唤醒一组终端设备，可以降低唤醒终端设备带来的资源开销。
进一步可选地，若网络设备向该组终端设备中的各个终端设备一一发送针对各个终端 设备的唤醒信号，那么网络设备向各个终端设备发送数据的传输时延可能会增加，因此，通过唤醒信号唤醒一组终端设备，那么该一组终端设备可以基于相同的唤醒信号接入网络设备，进而接收该网络设备发送的数据，从而可以降低传输时延。

基于上述技术方案，可通过唤醒信号中除第一子标识以外的子标识为第二子标识还是第三子标识区分唤醒信号是唤醒一个终端设备还是一组终端设备。
结合第一方面，在第一方面的某些实现方式中，第二子标识的取值为预设值。

1)核心网寻呼：指的是UE处于idle态时接收的寻呼，由核心网发起，核心网将被寻呼UE的UE ID发给将要发寻呼信息的网络设备。对于核心网寻呼，UE ID为5G系统架构演进(system architecture evolution，SAE)临时移动用户标识符(5G SAE temporary mobile station identifier，5G-S-TMSI)，长度如为48比特。5G-S-TMSI可由接入和移动性管理功能(access and mobility management function，AMF)分配。
2)接入网寻呼：指的是UE处于inactive态时接收的寻呼，由网络设备发起，该网络设备可将被寻呼UE的UE ID发给将要发寻呼信息的其他网络设备。该网络设备为UE由连接态(connected)态转为inactive态时UE所在的小区对应的基站。该小区也可称为最后一个服务小区(last serving cell)。对于接入网寻呼，UE ID为不激活态无线网络临时标识(inactive radio network temporary identifier，I-RNTI)，长度如为40比特。I-RNTI可由last serving cell分配。
应理解，上述关于执行寻呼接收的流程仅是示例性说明，例如可以参考相关标准，本申请不予限制。
2、主电路和唤醒电路
一般情况下，无论终端设备在idle态或者inactive态执行接收寻呼的流程时，还是终端设备在连接态进行数据接收时，都是用相同的接收模块，或者用相同的接收机，或者用相同的接收电路。在本申请中，为便于描述，将完成这些功能或执行相关步骤的模块称为主电路。可以理解，主电路仅是为区分做的命名，其具体命名不对本申请的保护范围造成限定。下文为便于说明，统一描述为主电路。
终端设备使用主电路接收的信号可以被称为在主链路上传输，其中，主链路表征了终端设备和网络设备间的一种连接关系，是一个逻辑概念，而非一个物理实体。可以理解， 主链路仅是为区分做的命名，其具体命名不对本申请的保护范围造成限定。
当终端设备采用主电路接收寻呼时，功耗较高。例如，终端设备在接收寻呼时，首先要使用主电路的接收模块接收下行信号，然后终端设备还要对PDCCH进行盲检，对接收到的PDSCH进行解码等，这些都会带来较大的功耗。此外，由于主电路较为复杂，其运行时的基准功耗或静态功耗比较高。
为了降低终端设备接收寻呼带来的功耗，一种可能的方法是，终端设备可以使用一个单独的低功耗小电路接收信号，终端设备使用该低功耗小电路接收的信号可称为低功率唤醒信号(low power wake up signal，LP-WUS)或者唤醒信号。作为示例，唤醒信号可用于指示寻呼相关的信息，该寻呼相关的信息例如可以包括：一个终端设备或者一组终端设备是否被寻呼。该低功耗小电路可以使用一个结构简单的单独的小电路或芯片实现，其功耗较低。该低功耗小电路例如可以称为唤醒无线电(wake up radio，WUR)，或者也可以称为唤醒电路，或者也可以称为低功耗电路，或者也可以称为唤醒接收机(wake up receiver，WUR)，等等，关于其命名，本申请不予限制。在本申请中，为便于描述，将该低功耗小电路称为唤醒电路。可以理解，唤醒电路仅是为区分做的命名，其具体命名不对本申请的保护范围造成限定。下文为便于说明，统一描述为唤醒电路。此外，下文为便于说明，将终端设备使用唤醒电路接收的信号称为唤醒信号。
终端设备使用唤醒电路接收的信号可以被称为在唤醒链路上传输，其中，唤醒链路表征了终端设备和网络设备间的一种连接关系，是一个逻辑概念，而非一个物理实体。可以理解，唤醒链路仅是为区分做的命名，其具体命名不对本申请的保护范围造成限定。
图2是终端设备通过唤醒电路接收唤醒信号的示意图。
如图2所示，当终端设备使用唤醒电路接收信号时，若终端设备未检测到与自己关联的唤醒信号，则继续使用唤醒电路接收信号，主电路可处于关闭状态或者睡眠状态；若终端设备检测到与自己关联的唤醒信号，则触发主电路的唤醒，即令主电路处于/切换为开启状态，该开启状态也可称为工作状态，或者称为活跃状态。主电路开启后，终端设备可以执行接收寻呼过程，例如，终端设备接收寻呼PDCCH，在自己对应的PO检测到寻呼PDCCH后，接收寻呼PDSCH。或者主电路开启后，终端设备可以直接执行接入流程。此时，唤醒电路接收到的唤醒信号可以直接指示被寻呼的UE，终端设备开启主电路后，不需要再通过主电路接收寻呼，而是直接发起随机接入。
为了保证功耗收益，唤醒信号可采用开关键控(on off key，OOK)调制，或者也可采用移频键控(frequency shift keying，FSK)调制。下面简单介绍一下这两种调制方式。
1)OOK：利用信号的发送与否来调制信息，对应的唤醒电路可采用包络检测的方法接收信号。OOK调制技术可以用复杂度很低的接收机就可以实现解调，故而能实现唤醒电路的低功耗目标。
图3是唤醒信号采用OOK调制时的波形示意图。
当信号采用OOK调制时，每个比特，即编码后的比特，可对应一个符号(symbol)。一个符号也可以被称为一个码片(chip)，也可以被称为其他名称，这里不做限制。
例如，当比特为1时，该符号长度内有信号发出(即该符号长度内信号发射功率不为0)；当比特为0时，该符号长度内无信号发出(即该符号长度内信号发射功率为0)。如图3所示，图3所示的波形可代表1010四个比特。
再例如，当比特为0时，该符号长度内有信号发出(即该符号长度内信号发射功率不为0)；当比特为1时，该符号长度内无信号发出(即该符号长度内信号发射功率为0)。在该情况下，图3所示的波形可代表0101四个比特。
2)FSK：是一种将信息调制在载波频率上的调制技术。在使用FSK调制时，一个符号可以携带至少一个比特信息。例如，假设需要传输的信息比特为0,1组成的序列，调制的信号在频域有4个可能的位置。举例来说，发送频率为f1的信号代表传输的是比特“00”，发送频率为f2的信号代表传输的是比特“01”，发送频率为f3的信号代表传输的是比特“10”，发送频率为f4的信号代表传输的是比特“11”。在接收端，可以使用鉴频电路，检测接收到的信号频率。若检测到信号频率为f1，则判断接收到的比特为00；若检测到信号频率为f2，则判断接收到的比特为01；若检测到信号频率为f3，则判断接收到的比特为10；若检测到信号频率为f4，则判断接收到的比特为11。
上面对本申请中涉及到的术语做了简单说明，下文实施例中不再赘述。
在一些场景下，如IoT场景，网络设备可以采用广播或组播的方式发送数据。例如，软件升级推送(software delivery over wireless)场景，具体来说，在网络中通过广播的方式一次性对所有终端发送软件升级包，避免重复多次单播传输(即网络设备到终端的点对点传输)浪费空口资源。再例如，视频监控场景，具体来说，在某些场景中，可能部署至少2个摄像头，为了节能可能只有部分摄像头处于长期开启状态，其他摄像头处于关闭状态。或者为了避免网络拥塞，虽然所有摄像头都有连接网络的能力，但是可能只有部分摄像头与网络始终保持连接(即该部分摄像头处于连接态)，其他摄像头未与网络连接(即该其他摄像头处于空闲态)。当处于连接态的摄像头检测到入侵事件后，上报网络，网络下发信息触发其他摄像头的唤醒或接入网络。
目前仅考虑了对单个UE的寻呼，在某些场景下，当网络设备采用广播或组播的方式发送数据时，网络设备要对所有需要接收该数据的UE一一发送寻呼，这样，不仅造成比较大的寻呼资源开销，而且由于各个UE的寻呼消息要一一先后发送，所以也会带来较大的传输时延。
有鉴于此，本申请提出一种方案，通过唤醒一组终端设备，来降低唤醒资源的开销，降低传输时延。
可以理解，本文中术语“和/或”，仅仅是一种描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B这三种情况。另外，本文中字符“/”，一般表示前后关联对象是一种“或”的关系。
下文将结合附图详细说明本申请实施例提供的方法。本申请提供的实施例可以应用于上述图1所示的网络架构中，不作限定。
图4是本申请一实施例提供的一种通信方法400的示意图。方法400可以包括如下步骤。
410，终端设备接收第一唤醒信号，第一唤醒信号用于唤醒终端设备组，终端设备组包括至少两个终端设备，且至少两个终端设备包括该终端设备。
每个终端设备组中可以包括至少两个终端设备，一个终端设备可以属于不同的终端设备组。
例如，终端设备1属于终端设备组1，终端设备1还属于终端设备组2。其中，终端 设备组1和终端设备组2可以是根据不同方式划分的。作为示例，终端设备组1是根据终端设备类型划分的，终端设备组2是根据区域划分的，也即终端设备组1中包括的终端设备为某种特定类型的终端设备，终端设备组2中包括的终端设备为某个区域内的终端设备。上述关于终端设备组的划分方式为示例性说明，本申请实施例关于终端设备组的划分方式不予限制。
420，终端设备根据第一唤醒信号接入网络设备。
终端设备根据第一唤醒信号接入网络设备，表示终端设备收到第一唤醒信号后，若获知自身被唤醒，则该终端设备接入网络设备。终端设备接入网络设备，例如可以是终端设备向网络设备发起随机接入。如终端设备向网络设备发送随机接入前导(preamble)。
基于本申请实施例，网络设备通过发送唤醒信号唤醒一组终端设备，也即该一组终端设备可以基于相同的唤醒信号接入网络设备。在某些场景下，如网络设备要向一组终端设备发送数据，相比于网络设备向该组终端设备中的各个终端设备一一发送针对各个终端设备的唤醒信号的方案，本申请实施例的方案，即通过相同的唤醒信号唤醒该组终端设备，可以降低唤醒终端设备带来的资源开销。进一步可选地，若网络设备向该组终端设备中的各个终端设备一一发送针对各个终端设备的唤醒信号，那么网络设备向各个终端设备发送数据的传输时延可能会增加，因此，通过发送唤醒信号唤醒一组终端设备，那么该一组终端设备可以基于相同的唤醒信号接入网络设备，进而接收该网络设备发送的数据，从而可以降低传输时延。
可选地，第一唤醒信号包括第一标识，第一标识与终端设备组关联。这样，若网络设备要唤醒一组终端设备，则网络设备可发送唤醒信号(为区分，称为第一唤醒信号)，并在该第一唤醒信号中携带第一标识，这样可通过该第一唤醒信号唤醒一组终端设备。其中，第一标识与终端设备组关联，表示第一标识可用于识别终端设备组。例如，第一标识为终端设备组的组标识。可选地，第一标识可以是网络设备(如last serving cell或last serving gNB)配置的，也可以是核心网配置的，不予限制。
网络设备可以唤醒终端设备组，在某些情况下，网络设备也可能需要唤醒一个终端设备。例如，若网络设备要单独给某个终端设备发送数据，则可以唤醒该终端设备，不需要唤醒该终端设备所在的终端设备。因此一种可能的实现方式，一个终端设备被配置至少两个标识，该至少两个标识均可用于唤醒终端设备，如一标识用于唤醒终端设备所在的终端设备组，另一标识用于唤醒终端设备。具体来说，网络设备在唤醒链路上发送唤醒信号时，可以在唤醒信号中携带为终端设备配置的标识，以唤醒该终端设备或该终端设备所在的终端设备组。
其中，该至少两个标识可以包括一个UE ID以及至少一个组ID。在本申请实施例中，为便于描述和区分，用UE ID表示一个终端设备的唤醒标识(如寻呼ID)，组ID表示一组终端设备的唤醒标识(如寻呼组ID)。UE ID和组ID的长度可以相同，也可以不同。
例如，网络设备要唤醒一个终端设备，则网络设备可发送唤醒信号，且该唤醒信号中包括该终端设备的UE ID；终端设备接收到该唤醒信号后，根据该唤醒信号中的UE ID获知自身被唤醒，进而可接入网络设备。
再例如，若网络设备要唤醒一组终端设备，则网络设备可发送唤醒信号，且该唤醒信号中包括该终端设备所在的终端设备组的组ID；终端设备接收到该唤醒信号后，根据该 唤醒信号中的组ID获知自身被唤醒，进而可接入网络设备。
可选地，终端设备判断网络设备唤醒终端设备自身，还是唤醒终端设备所在的终端设备组。一种可能的实现方式，终端设备根据唤醒信号中的标识是UE ID还是组ID，判断网络设备唤醒一个终端设备还是一组终端设备。
作为示例，终端设备判断网络设备唤醒终端设备自身和唤醒终端设备所在的终端设备组时，可执行不同的操作。例如，若终端设备判断网络设备唤醒终端设备自身，则终端设备可直接发起随机接入；若终端设备判断网络设备唤醒终端设备所在的终端设备组，则终端设备可直接监测网络设备广播的数据。
由上可知，在本申请实施例中，网络设备可以通过发送唤醒信号唤醒一个终端设备，也可以通过发送唤醒信号唤醒一组终端设备，下面介绍区分这两种唤醒方式的几种可能的方案。
方案1，第一唤醒信号包括第一信息，第一信息表征：第一唤醒信号用于唤醒终端设备组。
在该方案1下，若第一唤醒信号包括第一标识，则第一标识可以为该终端设备组的组ID，第一信息可表征：第一唤醒信号用于唤醒该第一标识所标识的终端设备组，也即第一标识所标识的终端设备组将要被唤醒。
第一信息的设计方式有很多，本申请实施例不予限制。
第一种可能的设计方式，若网络设备发送的唤醒信号中携带第一信息(如特定的字段)，则表示该唤醒信号用于唤醒终端设备组；若网络设备发送的唤醒信号中没有携带第一信息(如特定的字段)，则表示该唤醒信号用于唤醒一个终端设备。
第二种可能的设计方式，若网络设备发送的唤醒信号中携带第一信息，且该第一信息用于指示唤醒信号的格式为第一格式，则表示该唤醒信号用于唤醒终端设备组；若网络设备发送的唤醒信号中携带第一信息，且该第一信息用于指示唤醒信号的格式为第二格式，则表示该唤醒信号用于唤醒一个终端设备。基于该设计方式，可以通过定义不同格式(format)的唤醒信号区分两种唤醒方式。下面主要介绍第二种可能的设计方式。
基于该第二种可能的设计方式，若唤醒信号的格式为第二格式，则表示该唤醒信号用于唤醒一个终端设备；若唤醒信号的格式为第一格式，则表示该唤醒信号用于唤醒一组终端设备。
举例来说，若网络设备需要唤醒一个终端设备，或者网络设备需要单独唤醒各个终端设备，则网络设备发送唤醒信号(为区分，称为第三唤醒信号)，该第三唤醒信号中包括需要唤醒的终端设备的UE ID，且该唤醒信号的格式为第二格式；若网络设备需要唤醒一组终端设备，则网络设备发送第一唤醒信号，该第一唤醒信号中包括需要唤醒的终端设备组的组ID，且该唤醒信号的格式为第一格式。
图5是唤醒信号的示意图。
如图5所示，唤醒信号包括格式指示(第一信息的一例)，该格式指示用于指示唤醒信号的格式。唤醒信号中还包括需要唤醒的终端设备的UE ID或需要唤醒的终端设备组的组ID。举例来说，若唤醒信号用于唤醒一个终端设备，则唤醒信号中的该格式指示用于指示唤醒信号的格式为第二格式，且该唤醒信号中包括需要唤醒的终端设备的UE ID；若唤醒信号用于唤醒一组终端设备，则唤醒信号中的该格式指示用于指示唤醒信号的格式为 第一格式，且该唤醒信号中包括需要唤醒的终端设备组的组ID。
可选地，唤醒信号中还包括循环冗余校验(cyclic redundancy check，CRC)，且CRC可以位于结尾位置。
在该方案1中，UE ID和组ID的长度可以相同或不同，不同格式的唤醒信号的长度也可以相同或不同。举例来说，当UE ID和组ID的长度不同时，唤醒信号的格式为第二格式时的长度和唤醒信号的格式为第一格式时的长度可以相同或不同。例如，若组ID的长度小于UE ID的长度，唤醒信号的格式为第一格式时的长度可以小于唤醒信号的格式为第二格式时的长度，或者唤醒信号的格式为第一格式时的长度也可以等于唤醒信号的格式为第二格式时的长度。例如，若组ID的长度小于UE ID的长度，唤醒信号的格式为第一格式时的编码速率小于唤醒信号的格式为第二格式时的编码速率，令唤醒信号的格式为第二格式时的长度和唤醒信号的格式为第一格式时的长度相同。
基于上述方案，可通过定义不同格式的唤醒信号区分两种唤醒方式，也即通过唤醒信号的格式可区分该唤醒信号用于唤醒一个终端设备还是唤醒一组终端设备。
方案2，第一唤醒信号中包括第一标识，第一标识为终端设备组的组标识，组标识的取值属于第一取值范围，终端设备组中每个终端设备的标识的取值属于第二取值范围，第一取值范围和第二取值范围不同。
基于方案2，可通过UE ID和组ID的取值不同区分两种唤醒方式。UE ID和组ID的取值不同，也即任意一个终端设备的标识与任意一个终端设备组的标识的取值不同，这样可以根据取值区分两种唤醒方式。其中，UE ID和组ID的取值范围，可以是预定义的，如标准预定义的，或者也可以是网络设备分配的，不予限制。
以网络设备为终端设备分配UE ID和组ID为例，网络设备可基于第一取值范围为终端设备配置UE ID，基于第二取值范围为终端设备所在的终端设备组配置组ID，这样，可以实现UE ID和组ID的取值不同，进而可以区分唤醒信号用于唤醒一个终端设备还是一组终端设备。
举例来说，以唤醒信号中携带的标识的长度为224为例，标识的取值范围可以为0～224-1。作为示例，可以令组ID的取值范围为0～220-1(第一取值范围的一例)，UE ID的取值范围为220～224-1(第二取值范围的一例)。这样，组ID和UE ID的取值不同，从而可以根据不同的取值区分两种唤醒方式。
可选地，在该方案2中，用于唤醒一个终端设备的唤醒信号和用于唤醒一组终端设备的唤醒信号的格式相同。也即通过唤醒信号中携带的标识是UE ID还是组ID，即可区分是唤醒一个终端设备还是唤醒一组终端设备，进而不需要再设计两种格式的唤醒信号，以简化唤醒信号的设计。
基于上述方案2，可通过使得UE ID和组ID取值不同区分两种唤醒方式，也即通过唤醒信号中携带的标识可区分该唤醒信号用于唤醒一个终端设备还是唤醒一组终端设备。
方案3，第一唤醒信号中包括第一标识，第一标识包括第一子标识和第二子标识，第一子标识指示终端设备组，第二子标识表征：唤醒第一子标识指示的终端设备组。
其中，第一子标识指示终端设备组，表示通过该第一子标识可识别出终端设备组。作为示例，第一标识为终端设备组的组ID，第一子标识为组ID的部分ID(如前部分ID)。
类似地，若网络设备要唤醒一个终端设备，则网络设备发送唤醒信号(为区分，称为 第二唤醒信号)，第二唤醒信号包括该终端设备的UE ID，该UE ID包括第一子标识和第三子标识，第三子标识表征唤醒终端设备；相应地，终端设备接收第二唤醒信号，根据该第二唤醒信号，获知自身被唤醒，进而接入网络设备。
也就是说，基于方案3，可通过唤醒信号中除第一子标识以外的子标识为第二子标识还是第三子标识区分两种唤醒方式。
一种可能的实现方式，第二子标识和第三子标识可通过取值区分。例如，第二子标识的取值为预设值，第三子标识的取值为预设值之外的值。作为示例，预设值可以为全1或全0。在该方式下，UE ID的取值不同于组ID的取值。
举例来说，唤醒信号中的标识包括第一子标识和子标识#1，若该子标识#1的取值为预设值(此时该子标识#1为第二子标识的一例)，则携带该标识的唤醒信号用于唤醒该标识中的第一子标识所指示的一个终端设备组；若该子标识#1的取值为预设值之外的值(此时该子标识#1为第三子标识的一例)，则携带该标识的唤醒信号用于唤醒该标识所标识的一个终端设备。
图6是唤醒信号中的标识的示意图。
如图6所示，唤醒信号中的标识包括第一子标识和子标识#1。以唤醒信号中的标识的长度为16，第一子标识为11110000。
例如，若网络设备要唤醒一个终端设备，则网络设备发送第二唤醒信号，该第二唤醒信号中携带的标识为该终端设备的UE ID，该UE ID包括第一子标识和子标识#1，假设子标识#1为01010101，那么该UE ID为：11110000 01010101。
再例如，若网络设备要唤醒一组终端设备，则网络设备发送第一唤醒信号，该第一唤醒信号中携带的第一标识包括第一子标识和子标识#1，假设子标识#1的取值为预设值，且预设值为11111111或00000000，那么该第一标识为：11110000 11111111，或者，1111000000000000。可以看出，在该示例下，不同终端设备组之间可通过第一子标识进行区分，也即不同终端设备组的组ID，第一子标识不同，第二子标识可能相同，如第二子标识的取值均为预设值。
可以理解，上述主要以第二子标识和第三子标识通过取值区分为例进行的示例性说明，本申请实施例并未限定于此。例如，第二子标识和第三子标识也可通过长度区分，如第二子标识的长度为预设长度。
基于上述方案3，可通过唤醒信号中的标识包括第三子标识还是第二子标识区分该唤醒信号用于唤醒一个终端设备还是唤醒一组终端设备。
可以理解，上述三种方案为示例性说明，本申请实施例并未限定于此，属于上述三种方案的变形，都适用于本申请实施例。例如，作为上述方案3的一种可能变形，唤醒信号中的标识包括第一子标识和子标识#1，该第一子标识为组ID，若该子标识#1的取值为预设值，则携带该标识的唤醒信号用于唤醒该标识中的组ID所标识的一个终端设备组；若该子标识#1的取值为预设值之外的值，则携带该标识的唤醒信号用于唤醒该标识中的子标识#1所标识的一个终端设备，也即该子标识#1为终端设备的UE ID。在该方式下，UE ID的取值不同于预设值。作为示例，预设值可以为全1或全0。举例来说，假设终端设备的组ID为11110000，终端设备的UE ID为01010101。若网络设备要唤醒该终端设备，则网络设备发送唤醒信号，该唤醒信号中携带的标识为：11110000 01010101；若网络设备要 唤醒该终端设备所在的终端设备组，则网络设备发送唤醒信号，该唤醒信号中携带的标识为：11110000 11111111或11110000 00000000。
终端设备在idle态或者inactive态下的时候，与网络侧无交互，因此网络侧可能无法获知终端设备是在主链路上接收信号还是在唤醒链路上接收信号，即无法获知终端设备是在使用主电路还是在使用唤醒电路。为了避免无法唤醒终端设备，网络侧可以在主链路和唤醒链路上都发送唤醒相关的信息。以唤醒的方式为寻呼为例，网络侧可以在主链路和唤醒链路上都发送寻呼相关的消息。举例来说，若为核心网寻呼，核心网向网络设备发送寻呼相关的信息；若为接入网寻呼，last serving cell(或last serving gNB)向网络设备发送寻呼相关的信息。网络设备根据收到的寻呼相关的信息，在主链路和唤醒链路上都发送寻呼相关的消息。其中，寻呼相关的信息包括被寻呼终端设备的UE ID和/或被寻呼终端设备组的组ID。当被寻呼的为一组终端设备时，为了降低唤醒链路的寻呼开销，核心网或lastservingcell会将该组终端设备的组ID发给网络设备，同时为了在主链路能够发送寻呼，核心网或lastservingcell会将该终端设备组包括的各个终端设备的UE ID发给网络设备，网络设备收到被寻呼终端设备的UE ID和被寻呼终端设备组的组ID后，一种可能的方式，可以在唤醒链路上发送组ID，在主链路上发送UE ID。但是，网络设备收到被寻呼终端设备的UE ID和被寻呼终端设备组的组ID后，无法确定哪些UE ID与组ID关联，因此，网络设备在唤醒链路上可能会既发送组ID又发送UE ID，无法达到降低信令开销的目的。
下面列举一具体示例。
假设终端设备1和终端设备2属于同一个终端设备组，该终端设备组以及另一个终端设备3被寻呼。核心网或last serving cell向网络设备发送终端设备1、终端设备2和终端设备3的UE ID以及终端设备1和终端设备2所在的终端设备组的组ID，若网络设备无法获知终端设备组包括哪些终端设备，网络设备可能会在唤醒链路上发送终端设备1、终端设备2和终端设备3的UE ID以及终端设备1和终端设备2所在的组ID，以防止有些终端设备没有被寻呼到，这样会增加信令开销。有鉴于此，本申请实施例提供一种方案，网络设备从核心网或其他网络设备接收第二信息，第二信息包括第一标识(如组ID)与UE ID之间的关联关系。这样，网络设备可以获知第一标识(如组ID)与UE ID之间的关联关系，进而可以在唤醒链路上发送终端设备组的组ID，不需要在唤醒链路上再发送该终端设备组中所包含的终端设备的UE ID，从而降低信令开销。其中，其他网络设备例如为last serving cell或last serving gNB，不予限制。
以上述示例为例，若网络设备获知组ID与UE ID之间的关联关系，那么网络设备在唤醒链路上发送终端设备3的UE ID以及终端设备1和终端设备2所在的终端设备组的组ID即可，不需要再发送终端设备1的UE ID和终端设备2的UE ID。
下面介绍两种可能的实现方式。
第一种可能的实现方式，若唤醒终端设备组，则核心网或其他网络设备向网络设备发送被唤醒终端设备的UE ID时，指示该终端设备所属的被唤醒的终端设备组的组ID。
网络设备收到核心网或其他网络设备发送的信息后，若识别到一个终端设备所属的终端设备组被唤醒，则在唤醒链路上发送该终端设备组的组ID，不需要再发送该终端设备组内所包含的终端设备的UE ID。
考虑到一个终端设备可能属于至少两个终端设备组，且至少两个终端设备组可能同时 被唤醒，因此核心网或其他网络设备向网络设备发送被唤醒终端设备的UE ID时，可向网络设备指示该被唤醒终端设备所属的被唤醒终端设备组的组ID列表。
第一个示例，核心网或其他网络设备向网络设备指示终端设备所属的被唤醒的终端设备组的组ID时，可以以表1的形式指示。
表1
以表1为例，若唤醒UE ID#1和UE ID#2对应的终端设备，且唤醒组ID#1、组ID#2、组ID#3对应的终端设备组，网络设备基于上述表1可获知，组ID#1和UE ID#1关联，组ID#2和UE ID#2关联，组ID#3和UE ID#2关联，即组ID#1对应的终端设备组中包括UE ID#1对应的终端设备，组ID#2对应的终端设备组中包括UE ID#2对应的终端设备，组ID#3对应的终端设备组中包括UE ID#2对应的终端设备，因此网络设备在唤醒链路上发送组ID#1、组ID#2、以及组ID#3即可，不需要再发送UE ID#1和UE ID#2。此外，如表1所示，UE ID#3对应的组ID为空，如UE ID#3对应的组ID为空(null)，可以理解为该UE ID#3所标识的终端设备单独被唤醒，网络设备可以在唤醒链路上发送该UE ID#3，以唤醒该UE ID#3所标识的终端设备。
第二个示例，核心网或其他网络设备向网络设备指示终端设备所属的被唤醒的终端设备组的组ID时，可以以如下信令指示。
在上述信令中，PagingId用于指示被唤醒(如被寻呼)的终端设备的标识信息。作为示例，PagingId可以包含两个变量，UE-Id和associatedGroupIdList。
1)UE-Id用于指示UE ID，SIZE中的数字表示UE ID的长度。在该示例中，UE ID长度为48比特，因此SIZE中为48，若UE ID为其他长度，SIZE中的数字为对应值。关于UE ID的长度，本申请实施例不予限制。
2)associatedGroupIdList用于指示当前终端设备所属的终端设备组的组ID的列表。每个associatedGroupIdList可包含最多maxNrofGroup个AssociatedGroupId，每个AssociatedGroupId指示一个当前终端设备所属的终端设备组的组ID。其中，maxNrofGroup表示当前终端设备所属的终端设备组的最大值，也即当前终端设备最多属于maxNrofGroup终端设备组。在该示例中，组ID长度为48比特，因此SIZE中为48，若组ID为其他长度，SIZE中的数字为对应值。关于组ID的长度，本申请实施例不予限制。可以理解，associatedGroupIdList是一个可选参数，也即当唤醒终端设备所属的终端设备组时，核心网或其他网络设备可以向网络设备指示该参数；当唤醒终端设备且不用唤醒自 己所属的终端设备组时，核心网或其他网络设备可以不向网络设备指示该参数。
应理解，表1和上述信令设计仅是示例性说明，对此不予限制，任何属于表1和上述信令设计的变形，都适用于本申请。例如，上述表1中可以包括更多数量的UE ID和/或组ID。
第二种可能的实现方式，若唤醒终端设备组，则核心网或其他网络设备向网络设备发送被唤醒终端设备组的组ID时，指示该终端设备组中包括的终端设备的UE ID。
网络设备收到核心网或其他网络设备发送的信息后，若识别到一个终端设备所属的终端设备组被寻呼，则在唤醒链路上发送该终端设备组的组ID，不需要再发送该终端设备组内所包含的终端设备的UE ID。
考虑到一个终端设备组中包括至少两个终端设备，因此核心网或其他网络设备向网络设备发送被唤醒终端设备组的组ID时，指示该终端设备组中包括的终端设备的UE ID列表。基于该第二种可能的实现方式，若终端设备组被唤醒，则核心网或其他网络设备向网络设备指示被唤醒的该终端设备组的组ID所包含的UE ID列表即可，不需要再单独指示该终端设备组中包括的终端设备的UE ID。此外，若单个终端设备被唤醒，则核心网或其他网络设备也可以向网络设备指示被唤醒的该终端设备的UE ID。
第一个示例，核心网或其他网络设备向网络设备指示终端设备组中包括的终端设备的UE ID时，可以以表2的形式指示。
表2
以表2为例，若组ID#1和组ID#2对应的终端设备组被唤醒，则网络设备在唤醒链路上发送组ID#1和组ID#2即可，不需要再发送UE ID#1、UE ID#2、UE ID#3、UE ID#4、以及UE ID#5。
第二个示例，核心网或其他网络设备向网络设备指示终端设备所属的被唤醒的终端设备组的组ID时，可以以如下信令指示。
在上述信令中，UE-Id用于指示UEID SIZE中的数字表示UE ID的长度。在该示例中，UE ID长度为48比特，因此SIZE中为48，若UE ID为其他长度，SIZE中的数字为对应值。关于UE ID的长度，本申请实施例不予限制。
PagingGroupInfo用于指示被唤醒(如被寻呼)的终端设备组的信息，PagingGroupInfo包含两个变量，GroupId和associatedUE-IdList。
1)GroupId用于指示组ID。在该例中，组ID长度为48比特，因此SIZE中为48，若组ID为其他长度，SIZE中的数字为对应值。关于组ID的长度，本申请实施例不予限制。
2)associatedUE-IdList用于指示当前终端设备组包含的终端设备的UE ID的列表。每个associatedUE-IdList可包含最多maxNrofUE个UE ID。其中，maxNrofUE表示当前终端设备组中包括的终端设备的最大值。
应理解，表2和上述信令设计仅是示例性说明，对此不予限制，任何属于表2和上述信令设计的变形，都适用于本申请。例如，上述表2中可以包括更多数量的UE ID和/或组ID。
上述两种可能的实现方式，可以单独使用，也可以与前面的方案结合使用，如与前面的方案1和方案2结合使用。
可以理解，上述为核心网或其他网络设备向网络设备指示组ID与UE ID之间的关联关系，为示例性说明，本申请实施例并未限定于此。例如，另一种可能的方案，若唤醒终端设备组，则核心网或其他网络设备向网络设备发送该终端设备组的组ID，不需要向网络设备发送该终端设备组中所包含的终端设备的UE ID。这样，也可以避免网络设备在唤醒链路上既发送终端设备组的组ID，还发送该终端设备组中的终端设备的UE ID。
例如，承载组ID和UE ID的信元不同，为区分，将承载组ID的信元记为信元#1，承载UE ID的信元记为信元#2。若唤醒终端设备组，则核心网或last serving cell向网络设备发送信元#1，该信元#1包括组ID；网络设备收到该信元#1后，可知该信元#1承载的标识为组标识(即组ID)，因此，网络设备在唤醒链路上发送该组ID。
再例如，组ID和UE ID的取值范围不同，如前面的方案2。网络设备收到标识后，可根据标识的取值确定该标识为组标识(即组ID)，进而在唤醒链路上发送该组ID。
上面主要介绍了关于组ID和UE ID的相关方案，下面介绍关于唤醒信号的频率资源的相关方案。
唤醒信号和其他信号可采用频分复用(frequency division multiplexing，FDM)方式部署。举例来说，假设系统带宽为F，那么可以将其中的部分频率资源分配给唤醒信号，其余的频率资源分配给小区中的其他信号使用。作为示例，分配给唤醒信号的频率资源可包括至少两个子带(subband)。该至少两个子带可以是不连续的子带，也可以是连续的子带，不予限制。可以理解，子带，也可以替换为以下任一项：窄带(narrow band)、带宽部分(bandwidth part，BWP)、频率区间、物理资源块(physical resource block，PRB)、或资源块组(resource block group，RBG)等，不予限制。
图7是唤醒信号和其他信号所占的频率资源的示意图。
如图7所示，分配给唤醒信号的子带包括子带1和子带2，也即网络设备可以在子带1和子带2上发送唤醒信号，在除子带1和子带2之外的子带上发送其他信号。这样，终端设备可以在该子带1和/或子带2上监测唤醒信号即可。
在某些情况下，例如小区内业务负载发生变化等，网络设备发送唤醒信号所使用的频率资源可能会发送变化。以图7为例，网络设备可能会从原先的在子带1和子带2上发送唤醒信号，变为在子带1上发送唤醒信号，也即不在子带2上发送唤醒信号。若终端设备还是在原先的子带1和/或子带2上监测唤醒信号，则可能会监测不到唤醒信号或者不能及时的监测到唤醒信号。对此，本申请实施例提供一种方式，可以使得终端设备能够正确接收唤醒信号。
图8是本申请另一实施例提供的一种通信方法800的示意图。方法800可以包括如下 步骤。
810，终端设备接收指示信息，指示信息用于指示第一频率资源的配置信息发生更新，或者指示信息用于唤醒在第一频率资源上监测唤醒信号的所有终端设备，唤醒信号用于唤醒至少一个终端设备。
相应地，网络设备发送指示信息。
其中，指示信息用于指示第一频率资源的配置信息发生更新，可以替换为以下任一项：指示信息用于指示唤醒链路的配置信息发生更新，指示信息用于指示唤醒电路的配置信息发生更新，或者指示信息用于指示唤醒信号的配置信息发生更新。类似地，指示信息用于唤醒在第一频率资源上监测唤醒信号的所有终端设备，也可以替换为以下任一项：指示信息用于唤醒在唤醒链路上监测唤醒信号的部分或全部终端设备，指示信息用于唤醒在唤醒电路上监测唤醒信号的部分或全部终端设备。
作为一种可能的情况，指示信息用于唤醒在唤醒链路上监测唤醒信号的部分终端设备。举例来说，分配给唤醒链路的频率资源包括第一部分频率资源和第二部分频率资源，若第一部分频率资源的配置信息发生更新，第二部分频率资源的配置信息未发生更新，则指示信息可用于唤醒在第一部分频率资源上监测唤醒信号的终端设备，也即可以不用唤醒在第二部分频率资源上监测唤醒信号的终端设备。以图7中的示例为例，指示信息可用于唤醒在子带2上监测唤醒信号的终端设备，也即可以不用唤醒在子带1上监测唤醒信号的终端设备。
作为另一种可能的情况，指示信息用于唤醒在唤醒链路上监测唤醒信号的全部终端设备。举例来说，只要唤醒链路的配置信息发生更新，则指示信息用于唤醒在该唤醒链路上监测唤醒信号的全部终端设备。以图7中的示例为例，指示信息可用于唤醒在子带1和子带2上监测唤醒信号的全部终端设备。
可选地，第一频率资源为唤醒链路对应的频率资源，或者，第一频率资源为唤醒链路对应的部分子带。若第一频率资源为唤醒链路对应的部分子带，该部分子带可以为更新的子带。以上述图7为例，第一频率资源可以为唤醒链路对应的频率资源，即子带1和子带2；或者第一频率资源也可以为唤醒链路对应的部分子带，如子带2。
820，终端设备根据指示信息，使用第二频率资源接收来自网络设备的信息或者接入网络设备。
相应地，网络设备使用第二频率资源向终端设备发送信息，或者，网络设备使用第二频率资源接收来自终端设备的随机接入前导。
可选地，终端设备使用第二频率资源接收来自网络设备的信息，包括：终端设备使用第二频率资源接收来自网络设备的第一频率资源的配置信息。也即，终端设备使用第二频率资源接收更新后的第一频率资源的配置信息。
以终端设备使用第二频率资源接收来自网络设备的信息为例，终端设备使用第二频率资源接收来自网络设备的信息，可替换为以下任一项：终端设备通过主电路接收来自网络设备的信息，或者终端设备在主链路上接收来自网络设备的信息。
其中，第一频率资源的配置信息，可以表示与唤醒链路相关的配置信息。作为示例，第一频率资源的配置信息包括以下至少一项信息：第一频率资源的带宽、第一频率资源的频域位置、或唤醒信号的配置信息。其中，唤醒信号的配置信息例如可以包括以下至少一 项：唤醒信号的长度、唤醒信号的格式、或同步信号的相关信息。终端设备基于该第一频率资源的配置信息，可获知第一频率资源的位置和/或其他相关配置，进而可在该第一频率资源上正确监测唤醒信号。
可选地，终端设备使用第二频率资源接收来自网络设备的信息，包括：终端设备根据使用第二频率资源接收来自网络设备的第一频率的配置信息，或者，终端设备根据使用第二频率资源接收来自网络设备的唤醒链路的配置信息。
可选地，第二频率资源为主链路对应的频率资源，或者，第二频率资源为主链路对应的部分频率资源。以上述图7为例，第二频率资源可以为子带1和子带2之外的频率资源，或者第二频率资源可以为子带1和子带2之外的部分频率资源。
下面以唤醒链路和主链路为例，结合指示信息的不同内容，介绍两种可能的情形。
第一种可能的情形，网络设备向终端设备发送指示信息，该指示信息用于指示唤醒链路的配置信息发生更新。
举例来说，若唤醒链路的配置信息发生更新，则网络设备向终端设备发送指示信息，指示配置链路的配置信息发生更新；相应地，终端设备接收该指示信息，并且根据该指示信息确定唤醒链路的配置信息发生更新，进而终端设备可切换至主链路，并在主链路上接收更新后的唤醒链路的配置信息。
一示例，网络设备向终端设备发送预设标识；终端设备接收该预设标识，并根据该预设标识，获知唤醒链路的配置信息发生更新。其中，预设标识可指示唤醒链路的配置信息发生更新，换句话说，若终端设备接收到预设标识，则终端设备在主链路上接收更新后的唤醒链路的配置信息。
例如，预设标识可以为取值为预设值的标识，如预设标识的取值为“全0”或“全1”。其中，预设标识和UE ID的长度可以相同，也可以不同。预设标识和组ID的长度可以相同，也可以不同。
再例如，预设标识可以为长度为预设长度的标识，如预设标识的长度小于终端设备的UE ID或组ID的长度，又如预设标识的长度大于终端设备的UE ID或组ID的长度。
可以理解，上述为示例性说明，关于指示信息的具体形式，本申请实施例不予限制。
第二种可能的情形，网络设备向终端设备发送指示信息，该指示信息用于唤醒在唤醒链路上监测唤醒信号的部分或全部终端设备。
举例来说，若唤醒链路的配置信息发生更新，则网络设备发送唤醒信号，该唤醒信号用于唤醒一个小区内所有监测唤醒信号的终端设备，或者该；相应地，终端设备接收唤醒信号，并切换至主链路。终端设备切换至主链路后，可在主链路上接收来自网络设备的信息，或者接入网络设备，进而可以在主链路上接收到更新后的唤醒链路的配置信息。
一示例，网络设备向终端设备发送唤醒信号，唤醒信号中的标识为预设标识；终端设备接收唤醒信号，并根据唤醒信号中的标识为预设标识，获知自身被唤醒，因此终端设备可切换至主链路，接收来自网络设备的信息或者接入网络设备。其中，预设标识可隐含指示唤醒一个小区内所有监测唤醒信号的终端设备。
例如，预设标识可以为取值为预设值的标识，如预设标识的取值为“全0”或“全1”。其中，预设标识和UE ID的长度可以相同，也可以不同。预设标识和组ID的长度可以相同，也可以不同。
再例如，预设标识可以为长度为预设长度的标识，如预设标识的长度小于终端设备的UE ID或组ID的长度，又如预设标识的长度大于终端设备的UE ID或组ID的长度。
在上述两种可能的实现方式中，可选地，终端设备在主链路上接收更新后的唤醒链路的配置信息后，可在满足预设条件的情况下，切换至唤醒链路工作。其中，预设条件，例如可以包括：终端设备与网络设备之间的距离较近，和/或，终端设备的移动速度较慢。其中，终端设备与网络设备之间的距离较近，表示终端设备位于网络设备网络较强的位置。在终端设备与网络设备之间的距离较近的情况下，终端设备可以切换至唤醒链路工作。可选地，终端设备可以通过测量服务小区的信号质量(或者信道质量)，判断终端设备与网络设备之间的距离。可选地，终端设备可以通过测量服务小区的信号质量变化量，判断终端设备的移动速度。
在上述两种可能的实现方式中，主要以网络侧主动通知终端设备，使得终端设备可以快速获取更新后的唤醒链路的配置信息。对此，不予限制，例如终端设备也可以主动获取更新后的唤醒链路的配置信息。作为示例，终端设备对唤醒链路进行测量，在一段时间内收不到参考信号(例如周期性同步信号)，终端设备认为自己离开唤醒信号覆盖范围，从而切换至主链路。这样，终端设备也可以在主链路上接收唤醒链路的配置信息。
可以理解，上述主要以唤醒信号唤醒一组终端设备为例进行示例性说明，本申请实施例并未限定于此。例如，唤醒信号还可以唤醒至少两组终端设备。
还可以理解，在本申请的各实施例中，“监测”也可替换为“检测”或者“读取”。例如，“监测唤醒信号”也可以替换为“检测唤醒信号”或“读取唤醒信号”。
还可以理解，在上述一些实施例中，提到了“传输”，在未作出特别说明的情况下，传输，包括接收和/或发送。例如，传输信号，可以包括接收信号和/或发送信号。
还可以理解，在本申请的各实施例中，若终端设备获知自身被唤醒，如基于唤醒信号获知自身被唤醒，则终端设备可以立即接入网络设备，或者终端设备也可以间隔一段时间接入网络设备，不予限制。
还可以理解，在上述一些实施例中，主要以主链路和唤醒链路为例进行了示例性说明，本申请不限于此。例如，“唤醒链路”也可以替换为“第一模块”，或者也可以替换为“唤醒电路”，或者也可以替换为“处于第一状态”，或者也可以替换为“处于第一模式”。举例来说，“终端设备在唤醒链路上接收信号”，也可以替换为“终端设备通过第一模块(或唤醒电路)接收信号”。“主链路”也可以替换为“第二模块”，或者也可以替换为“主电路”，或者也可以替换为“处于第二状态”，或者也可以替换为“处于第二模式”。举例来说，“终端设备在主链路上接收信号”，也可以替换为“终端设备通过第二模块(或主电路)接收信号”。
还可以理解，在本申请的各实施例中，主要以终端设备和网络设备之间的交互为例进行示例性说明，本申请不限于此，终端设备可以替换为接收端设备，接收端设备可以为终端设备或网络设备；网络设备可以替换为发送端设备，发送端设备可以为终端设备或网络设备。示例地，“终端设备”可以替换为“第一终端设备”，“网络设备”可以替换为“第二终端设备”。
还可以理解，本申请的各实施例中的一些可选的特征，在某些场景下，可以不依赖于其他特征，也可以在某些场景下，与其他特征进行结合，不作限定。
还可以理解，本申请的各实施例中的方案可以进行合理的组合使用，并且实施例中出 现的各个术语的解释或说明可以在各个实施例中互相参考或解释，对此不作限定。
