技术领域
本申请实施例涉及通信技术领域，尤其涉及一种通信方法、装置及***。
背景技术
为了满足人们日益增长的流量诉求，无线网络处于快速建设中。在建设过程中，随着有源天线(activeantennaunit，AAU)大规模商用，接入网设备侧的天线数量显著增加，以致功耗成倍增长。此外，为了满足更高的数据速率以及更大的流量，传输带宽增加，以致功耗增加。进一步地，随着毫米波、太赫兹的使用，站点的部署密度，以致能耗进一步增加。因此，如何降低功耗已成为重要问题。
发明内容

具体实施方式
本申请实施例公开了一种通信方法、装置及***，用于降低功耗。以下分别进行详细说明。
为了更好地理解本申请实施例公开的一种通信方法、装置及***，下面先对本申请实施例使用的网络架构进行描述。请参阅图1，图1是本申请实施例公开的一种网络架构示意图。如图1所示，该网络结构可以包括终端设备101、接入网设备102和核心网设备103。终端设备101与接入网设备102之间的通信可以包括上行通信(即终端设备101到接入网设备102的通信)和下行通信(即接入网设备102到终端设备101的通信)。在上行通信中，终端设备101，用于向接入网设备102发送上行信号；接入网设备102，用于接收来自终端设备101的上行信号。在下行通信中，接入网设备102，用于向终端设备101发送下行信号；终端设备101，用于接收来自接入网设备102的下行信号。核心网设备103与接入网设备102之间进行通信。
终端设备，又可以称之为UE、移动台(mobile station，MS)、移动终端(mobile terminal，MT)等，是一种向用户提供语音和/或数据连通性的设备。终端设备可以为手持终端、客户终端设备(customer premise equipment，CPE)笔记本电脑、用户单元(subscriber unit)、蜂窝电话(cellular phone)、智能电话(smart phone)、无线数据卡、个人数字助理(personal digital assistant，PDA)电脑、平板型电脑、无线调制解调器(modem)、手持设备(handheld)、膝上型电脑(laptop computer)、会话启动协议(session initiation protocol，SIP)电话、无绳电话(cordless phone)或者无线本地环路(wireless local loop，WLL)台、机器类型通信(machine type communication，MTC)终端，可穿戴设备(如智能手表、智能手环、计步器等)，车载设备(如汽车、自行车、电动车、飞机、船舶、火车、高铁等)、虚拟现实(virtual reality，VR)设备、增强现实(augmented reality，AR)设备、工业控制(industrial control)中的无线终端、智能家居设备(如冰箱、电视、空调、电表等)、智能机器人、车间设备、无人驾驶(self driving)中的无线终端、远程手术(remote medical surgery)中的无线终端、智能电网(smart grid)中的无线终端、运输安全(transportation safety)中的无线终端、智慧城市(smart city)中的无线终端，或智慧家庭(smart home)中的无线终端、飞行设备(如智能机器人、热气球、无人机、飞机等)或其他可以接入网络的设备。
接入网设备为终端设备提供无线接入的设备，主要负责空口侧的无线资源管理、服务质量(qualityofservice，QoS)流管理、数据压缩和加密等功能。接入网设备可以包括各种形式的基站，例如：宏基站，微基站(也称为小站)，中继站，接入点等。接入网设备还可以包括长期 演进(long term evolution，LTE)中的演进型基站(evolved Node B，eNB或eNodeB)；或者5G网络中的基站gNB或者未来演进的公共陆地移动网络(public land mobile network，PLMN)中的基站，宽带网络业务网关(broadband network gateway，BNG)，汇聚交换机或者非第三代合作伙伴项目(3rd generation partnership project，3GPP)接入设备等、无线保真(wireless fidelity，WiFi)接入节点(access point，传输接收点(transmitting and receiving point，TRP)、发射点(transmitting point，TP)、移动交换中心以及设备到设备(Device-to-Device，D2D)、车辆外联(vehicle-to-everything，V2X)、机器到机器(machine-to-machine，M2M)通信中承担基站功能的设备等。
核心网设备，是指为终端设备提供业务支持的核心网(core network，CN)中的设备。核心网络设备在不同的通信***可以对应不同的设备。例如，在***移动通信技术(4th generation mobile networks，4G)中可以对应移动管理实体(mobility management entity，MME)、服务网关(serving gateway，S-GW)等中的一个或多个。再例如，在5G中可以对应接入和移动性管理功能(access and mobility management function，AMF)网元、会话管理功能(session management function，SMF)网元、用户面功能(user plane function，UPF)网元等中的一个或多个网元。在下一代通信***或未来通信设备中可以为终端设备提供业务支持的一个或多个网元、设备或实体。
需要说明的是，图1所示的网络架构中不限于仅包括图中所示的终端设备、接入网设备和核心网设备，还可以包括其它未在图中表示的终端设备、接入网设备和核心网设备，具体本申请在此处不再一一列举。

为了更好地理解本申请实施例公开的一种通信方法、装置及***，下面先对本申请实施例使用的应用场景进行描述。在独立组网(standalone，SA)场景，终端设备与单个接入网设备连接。终端设备所连接的接入网设备，以及接入网设备所连接的核心网设备的制式相同，即接入网设备与核心网设备的制式相同。请参阅图2，图2是本申请实施例公开的一种独立组网场景的示意图。如图2所示，终端设备连接的接入网设备和核心网设备的制式均为RAT1。RAT1可以为LTE，也可以为5G，还可以为6G，还可以为面向未来的无线接入技术。
在双连接(dualconnectivity，DC)场景中，终端设备可以同时与两个接入网连接，这两个接入网的制式可以相同，也可以不同。这两个接入网连接同一个核心网，这个核心网与这两个接入网中的至少一个接入网的制式相同。请参阅图3，图3是本申请实施例公开的一种DC场景的示意图。如图3所示，终端设备可以同时与RAT1接入网和RAT2接入网连接。RAT1接入网和RAT2接入网可以同时与RAT1核心网或RAT2核心网连接。RAT1与RAT2可以不同，此时，RAT1接入网可以作为主站(或辅站)，RAT2接入网可以作为辅站(或主站)。RAT1与RAT2可以相同，此时，主站和辅站相同。
例如，核心网可以为5G核心网，两个接入网可以分别为5G接入网和6G接入网，5G接入网可以作为主站(或辅站)，6G接入网可以作为辅站(或主站)。再例如，核心网可以为6G核心网，两个接入网可以分别为5G接入网和6G接入网，6G接入网可以作为主站(或主站)， 5G接入网可以作为辅站(或主站)。再例如，核心网可以为5G核心网，两个接入网可以均为5G接入网，主站和辅站均为5G接入网。再例如，核心网可以为6G核心网，两个接入网可以均为6G接入网，主站和辅站均为6G接入网。
为了更好地理解本申请实施例，下面先对相关概念或用语进行描述。
主小区组(mastercellgroup，MCG)是与主节点(即主站)相关联的一组服务小区，可以包括主小区(primarycell，PCell)。此外，MCG还可以包括一个或多个辅小区(secondarycell，SCell)。
主节点为在多无线电双连接(multi RAT DC，MR-DC)中，为核心网提供控制平面连接的无线接入节点。
辅小区组(secondarycellgroup，SCG)是与辅节点(即辅站)相关联的一组服务小区，可以包括主辅小区(primaryecondarycell，PSCell)。此外，SCG还可以包括一个或多个SCell。
辅节点为在MR-DC情况中，与核心网无控制平面连接，为终端设备提供额外资源的无线接入节点。
PCell为在MCG中终端设备发起初始接入的小区。
PSCell为在SCG下终端设备发起初始接入的小区。
请参阅图4，图4是本申请实施例公开的一种MCG和SCG的示意图。如图4所示，MCG包括的PCell和SCell可以通过载波聚合(carrieraggregation，CA)技术联合在一起。同理，SCG包括的PSCell和SCell也可以通过CA技术联合在一起。
请参阅图5，图5是本申请实施例公开的一种特殊小区(specialcell，SpCell)的示意图。如图5所示，在DC场景下，SpCell可以是MCG中的PCell，也可以是SCG中的PSCell。在非DC场景下，SpCell可以是PCell。
为了更好地理解本申请实施例，下面先对本申请实施例的相关技术进行描述。
为了满足人们日益增长的流量诉求，无线网络一直处于快速建设中。随着网络规模越建越大，功耗持续增加，电费的支出极大的增加了运营商的成本。究其根本，导致功耗增长的主要原因包括如下几点：
1.随着AAU大规模商用，接入网设备侧的天线个数显著增加，相比3G、4G时代，功耗成倍增长；
2.由于需要支持更高的数据速率，以及更大的流量，因此，会有更多的传输带宽，以致功耗增加；
3.随着毫米波以及太赫兹的使用，导致站点部署较为密集，以致功耗增加。
除了功耗增加导致运营商的成本大幅增加外，节能减排对于运营商而言，也是一项社会责任。因此，如何降低功耗已成为一个亟待解决的技术问题。
在DC场景，可以支持主站和辅站采用相同的RAT，也可以采用不同的RAT。5G版本15(release 15，R15)中规定辅站的激活和去激活可以完全依赖于RRC信令配置，即：通过RRC信令添加辅站后，辅站即处于激活状态，终端设备即可在辅站发起接入，完成接入后即可进行后续的数据传输；通过RRC信令删除辅站后，辅站即处于去激活状态，终端设备可以直接将辅站相关配置删除。
此外，在DC场景中，如果辅站发生变更，则需要在主站上通过RRC信令进行配置；如果主站发生变更，则需要通过给终端设备下发切换命令，让终端设备进行主载波的切换，当前的主 辅载波失效。
对于CA，仅支持主载波和辅载波采用相同的RAT。R15中CA的激活去激活依赖于RRC信令和MAC CE指示，即：可以通过RRC信令添加或者删除辅载波，对于通过RRC信令添加辅载波场景，辅载波添加后依然处于去激活状态，之后可以通过MAC CE来进行激活指示；相应地，对于激活后的载波，也可以通过MAC CE来进行辅载波的去激活。请参阅图6，图6是本申请实施例公开的一种MAC CE指示的示意图。如图6所示，MAC CE可以使用一个八字节激活/去激活SCell，也可以使用四个八字节激活/去激活SCell。图6是以比特位图的方式指示激活/去激活SCell，R表示预留(reserved，R)比特，剩余比特为有效比特，每个有效比特用于指示激活/去激活对应的载波。例如，在比特的值为“0”的情况下，指示去激活，在比特的值为“1”的情况下，指示激活。
应理解，图6是对MAC CE指示的示例性说明，并不对MAC CE指示构成限定。例如，MAC CE还可以使用两个或三个八字节激活/去激活SCell。再例如，MAC CE可以使用一个四字节激活/去激活SCell。
为了进一步的降低辅载波激活时间，5G版本16(release 16，R16)中在R15的基础上作了进一步的增强，规定支持通过RRC信令直接配置辅载波状态，即：对于辅载波初始添加、RRC恢复过程中的辅载波恢复/添加、切换过程中目标辅载波的配置，都可通过RRC信令指示辅载波的状态为激活态。
此外，对于CA场景，如果主载波发生变更，如当前主载波上的信号突然变差导致无线链路失败，则可以通过给终端设备下发切换命令，让终端设备进行主载波的切换，当前的主载波失效。如果辅载波发生变更，则需要在主站上通过RRC信令进行配置。
然而，在CA和DC结合的情况下，如果主站和辅站采用不同的RAT，则辅载波的添加或者删除需要在主站和辅站分别进行通知，以致造成传输资源浪费。
对于CA场景，通过切换命令来进行主载波的变更，这会导致比较长的业务中断时间；在辅载波变更的情况下，需要通过RRC重配置进行配置，以致造成传输资源浪费。
请参阅图7，图7是本申请实施例公开的一种通信方法的交互示意图。在该通信方法中：接入网设备可以向终端设备发送用于指示关断M个载波组的第一指示信息，终端设备可以根据第一指示信息关断M个载波组中的载波。如图7所示，该通信方法可以包括以下步骤。
701.接入网设备向终端设备发送用于指示关断M个载波组的第一指示信息。
相应地，终端设备接收来自接入网设备的用于指示关断M个载波组的第一指示信息。
接入网设备可以判断是否满足第一条件，在判断出满足第一条件的情况下，可以确定需要进行载波组关断，可以先确定需要关断的M个载波组，之后可以向终端设备发送第一指示信息。
在一个载波被关断后，接入网设备与终端设备之间不通过这个载波进行通信，即终端设备与接入网设备不通过这个载波传输信息。关断载波可以理解为去激活载波，也可以理解为删除载波，还可以理解为关闭载波，还可以理解为休眠载波，此处不做具体限定。
接入网设备可以根据用户数、负载情况等，判断是否满足第一条件。例如，接入网设备可以判断是否存在各载波上的在线用户数小于第一阈值的载波组，即判断所有载波组中是否存在各载波上的在线用户数小于第一阈值的载波组，在判断出至少一个载波组中各载波上的在线用户数小于第一阈值的情况下，确定满足第一条件。再例如，接入网设备可以判断是否存在各载波上的数据量小于第二阈值的载波组，在判断出至少一个载波组中的各载波上的数据量小于第二阈值的情况下，确定满足第一条件。再例如，接入网设备可以判断是否存在各载波上的资源 块(resourceblock，RB)利用率小于第三阈值的载波组，在判断出至少一个载波组中各载波上的RB利用率小于第三阈值的情况下，确定满足第一条件。在线用户数，可以理解为该载波上处于连接态的用户数量。数据量，可以理解为用户待发送的上行数据总和，和/或待发送给用户的下行数据总和。
第一指示信息可以用于指示关断M个载波组。M个载波组中每个载波组可以包括一个载波，也可以包括多个载波，M为大于或等于1的整数。可见，接入网设备可以指示终端设备关断一个载波组，也可以指示终端设备关断多个载波组。
下面对接入网设备发送第一指示信息的几种方式进行描述。
在一种情况下，接入网设备可以通过组播方式向终端设备发送第一指示信息。此时，上述终端设备可以为组播组内的终端设备中的任一终端设备。
第一指示信息还可以包括用于标识终端设备所在组的组标识，以便组播组内的终端设备能够根据该组标识成功接收到第一指示信息，而组播组外的终端设备无法成功接收到第一指示信息，可以保证信息传输的可靠性。
M个载波组可以为接入网设备为组播组内所有终端设备配置的载波组中的部分载波组，也可以为接入网设备为组播组内所有终端设备配置的载波组中的全部载波组。
例如，组播组可以包括三个终端设备，接入网设备为这三个终端设备配置的载波组分别为载波组1、载波组2和载波组3，M个载波组可以为这三个载波组中的载波组1、载波组2或载波组3，也可以为载波组1和载波组2，还可以为载波组1和载波组3，还可以为载波组2和载波组3，还可以为载波组1、载波组2和载波组3。
可选的，接入网设备通过组播方式传输第一指示信息所需的加密相关信息，如加密算法、秘钥、组标识等，接入网设备可以预先通过单播方式配置给组播组内的每个终端设备。即在接入网设备通过组播方式向终端设备发送第一指示信息之前，接入网设备可以先通过配置信息向组播组内的每个终端设备配置该组播相关的信息，如加密相关信息。例如，接入网设备可以通过RRC重配置消息进行配置组播相关的信息。
另一种情况下，接入网设备可以通过广播方式向终端设备发送第一指示信息。相应地，终端设备可以通过广播方式接收来自接入网设备的第一指示信息。此时，只要处于接入网设备覆盖范围内的终端设备均可以成功接收到第一指示信息，上述终端设备可以为处于接入网设备覆盖范围内的任一终端设备。
M个载波组可以为接入网设备为处于接入网设备覆盖范围内的终端设备配置的载波组中的部分载波组，也可以为接入网设备为处于接入网设备覆盖范围内的终端设备配置的载波组中的全部载波组。
又一种情况下，接入网设备可以通过单播方式向终端设备发送第一指示信息。
M个载波组可以为接入网设备为上述终端设备配置的载波组中的部分载波组，也可以为接入网设备为上述终端设备配置的载波组中的全部载波组。
接入网设备需要向多个终端设备指示关断载波组的指示信息的情况下，为了减少传输的信息或信令的数量，接入网设备可以通过组播方式或广播方式向终端设备发送第一指示信息。即为了减少传输的信令的数量，在属于M个载波组的载波被配置给了两个或两个以上终端设备的情况下，接入网设备可以通过组播方式或广播方式向终端设备发送第一指示信息。
为了减少传输的信令的数量，在M个载波组中的载波被配置给处于接入网设备覆盖范围内的所有终端设备的情况下，第一指示信息可以通过广播方式向终端设备发送第一指示信息。第一指示信息也可以通过组播方式进行传输，此时，可以有多个组播组，以便能够覆盖所有的终 端设备。
为了避免终端设备接收不必要的信息，以便降低终端设备的功耗，在M个载波组中的载波被配置给处于接入网设备覆盖范围内的部分终端设备的情况下，第一指示信息可以通过组播方式进行传输，此时，组播组可以仅包括这部分终端设备。
在接入网设备需要向一个终端设备发送指示关断载波组的指示信息的情况下，接入网设备可以通过单播方式向终端设备发送第一指示信息。
应理解，在接入网设备需要向多个终端设备发送第一指示信息，且采用单播方式的情况下，接入网设备可以通过单播方式分别向这多个终端设备发送第一指示信息。
应理解，接入网设备配置给同一终端设备的载波，可以属于同一载波组，也可以属于不同载波组，即接入网设备可以将同一载波组的部分或全部载波配置给一个终端设备，也可以将不同载波组的部分或全部载波配置给同一终端设备。例如，假设载波组1包括载波1、载波2和载波3，载波组2包括载波4和载波5，接入网设备可以将载波4和/或载波5配置给一个终端设备，也可以将载波1、载波2和载波3中的一个或多个载波，以及载波4和/或载波5配置一个终端设备。
M个载波组可以均正在被使用，也可以均未被使用，还可以部分载波组正在被使用部分载波组未被使用。
载波组正在被使用可以理解为属于载波组的载波中存在载波正在被使用。载波组未被使用可以理解为属于载波组的载波中不存在载波被正在使用。载波正在被使用可以理解为载波被激活但当前并未传输信息，也可以理解为载波被激活且正在用于传输信息。载波未被使用可以理解为载波未被激活，也可以理解为载波被激活但当前并未传输信息。
M个载波组中每个载波组包括的载波可以关联一个RAT，也可以关联多个RAT。在每个载波组关联一个RAT的情况下，M个载波组可以关联一个RAT，也可以关联多个RAT。
例如，假设一个载波组包括载波1、载波2和载波3。在载波1、载波2和载波3均为NR载波，或者均为6G载波的情况下，这个载波组包括的载波关联一个RAT，即NR或6G。在载波1为NR载波，载波2和载波3为6G载波的情况下，这个载波组包括的载波关联两个RAT，即NR和6G。
在接入网设备通过单播方式向终端设备发送第一指示信息的情况下，如果M个载波组关联多个RAT，接入网设备可以通过多个RAT中每个RAT对应的载波中的一个载波向终端设备发送第一指示信息。即M个载波组关联几个RAT，接入网设备就向终端设备发送几次第一指示信息，每次发送第一指示信息使用不同RAT对应的载波。可见，当为终端设备在某个RAT配置了多个载波的情况下，接入网设备仅需通过其中的一个载波向终端设备发送一次第一指示信息，而不需要在每个载波分别向终端设备发送第一指示信息，可以减少第一指示信息的发送数量，即减少信令的传输数量，从而可以节约传输资源。
例如，假设一个载波组包括载波1、载波2、载波3和载波4，载波1和载波4为NR载波，载波2和载波3为6G载波的情况下，接入网设备可以通过NR中的一个载波，即载波1或载波4，向终端设备发送第一指示信息，以及可以通过6G中的一个载波，即载波2或载波3，向终端设备发送第一指示信息。
在M个载波组关联多个RAT的情况下，接入网设备也可以仅通过多个RAT中的一个RAT的主载波或辅载波向终端设备发送一次第一指示信息。可见，不管M个载波组对应多少个RAT，M个载波组可以仅发送一次第一指示信息，可以减少第一指示信息的发送次数，从而可以节约传输资源。即用于关断M个载波组的指示信息可以不区分RAT。
M个载波组中至少存在一个载波组可以包括多个载波，可以减少信令的传输数量，从而可 以节约传输资源。此外，在一个载波组包括多个载波，且需要一个第一指示信息指示关断这多个载波的情况下，以载波为粒度时，第一指示信息需要同时指示关闭这多个载波，第一指示信息所需指示信息较多；而以载波组为粒度时，第一指示信息只需要指示关闭这个载波组，第一指示信息所需指示信息较少，可以减少第一指示信息中需要指示的信息数量，从而可以提高资源利用率。
例如，载波组1包括载波1、载波2和载波3。以载波为粒度时，第一指示信息需要指示关闭载波1、载波2和载波3，需要指示三个信息；而以载波组为粒度时，第一指示信息指示关闭载波组1，仅需要指示一个信息。
一种可能的实现中，接入网设备还可以向终端设备发送第二指示信息。相应地，终端设备可以接收来自接入网设备的第二指示信息。第二指示信息用于指示载波组的总数量，即接入网设备上的载波组的总数量。载波组的总数量可以大于M，也可以等于M。
在接入网设备上的载波组的总数量保持不变的情况下，接入网设备可以在每个终端设备接入的时候，向终端设备发送第二指示信息。即每个终端设备接入的时候，接入网设备只需要向终端设备发送一次第二指示信息即可，不需要重复发送。
在接入网设备上的载波组的总数量变动的情况下，接入网设备可以在每个终端设备接入的时候，向终端设备发送第二指示信息。接入网设备也可以在载波组的总数量发生变化的时候，向终端设备发送第二指示信息。
接入网设备可以通过广播方式向处于接入网设备覆盖范围内的终端设备发送第二指示信息，也可以通过组播方式向终端设备发送第二指示信息，还可以通过单播方式向终端设备发送第二指示信息。
一种情况下，第一指示信息可以为比特位图(bitmap)，比特位图至少包括K个比特。K为接入网设备上所有载波组的数量，即载波组的总数量。K个比特与K个载波组一一对应。K个比特中的每个比特用于指示是否关断对应的载波组。
一种实现方式中，协议可以规定比特位图包括的比特的数量，即比特位图的长度是固定不变的，但接入网设备可以根据载波组的总数量确定比特位图中的有效比特，剩余比特可以为预留(R)比特。
在此情况下，由于终端设备可以根据接入网设备发送第二指示信息确定载波组的总数量，从而确定比特位图中的有效比特。
一种可能方式中，协议可以定义、规定，或预定义比特位图中比特与载波组的对应关系。例如，协议可以规定第i比特用于指示是否关断第i个载波组。再例如，协议可以规定第i比特用于指示是否关断第K-i+1个载波组。此情况下，接入网设备不需要向终端设备指示每个有效比特与载波组的对应关系。
另一种可能方式中，接入网设备可以指示每个有效比特与载波组的对应关系。一种方式中，接入网设备可以预先向终端设备配置比特位图中每个比特与对应的载波组之间的对应关系。另一种方式中，第一指示信息可以包括比特位图中每个比特与对应的载波组之间的对应关系。比特位图中每个比特与对应的载波组之间的对应关系可以如表1所示：
表1
Figure PCTCN2022132646-appb-000001
Figure PCTCN2022132646-appb-000002
应理解，表1是对比特位图中每个比特与对应的载波组之间的对应关系的示例性说明，并不对其构成限定。
一种可能的实现中，可以预定义比特位图的长度为1个字节，即比特位图的长度为8比特。此时，比特位图最多能指示8个载波组。在载波组的总数量小于8的情况下，可以通过预留比特补齐。请参阅图8，图8是本申请实施例公开的一种比特位图的示意图。如图8所示，载波组的总数量为6，因此，比特位图中有6个有效比特，剩余的两个比特为预留比特。例如，在比特的值为1的情况下，可以指示关断对应的载波组，在比特的值为0的情况下，可以指示不关断对应的载波组。再例如，在比特的值为0的情况下，可以指示关断对应的载波组，在比特的值为1的情况下，可以指示不关断对应的载波组。再例如，在比特的值为1的情况下，可以指示关断对应的载波组，在比特的值为0的情况下，可以指示开启对应的载波组。i＝1,2,…,K。
又一种可能的实现中，可以预定义比特位图的长度为4个字节，即比特位图的长度为32比特。此时，比特位图最多能指示32个载波组。请参阅图9，图9是本申请实施例公开的另一种比特位图的示意图。如图9所示，载波组的总数量为15，因此，比特位图中有15个有效比特，剩余的17个比特为预留比特。
应理解，图8和图9是对比特位图的示例性说明，并不对其构成限定。例如，比特位图的长度还可以2个字节、3个字节等。例如，图8中的有效比特可以为后6个比特。
另一种实现方式中，比特位图包括的比特的数量不是固定的，接入网设备可以根据载波组的总数量确定比特位图包括的比特的数量(即比特位图的长度)，即比特位图包括的比特的数量可以等于载波组的总数量(即K)。
在此情况下，比特位图的长度即载波组的总数量。第1个载波组、第2个载波组、…、第K个载波组的标识可以是依次递增地，也可以是依次递减地。
举例说明，请参阅图10，图10是本申请实施例公开的又一种比特位图的示意图。如图11所示，载波组的总数量为8，比特位图包括8比特，8比特对8个载波组的标识一一对应。
应理解，图10是对比特位图的示例性说明，并不对其构成限定。例如，第i比特用于指示是否关断第K-i+1个载波组。
在第一指示信息为比特位图的情况下，如果所有载波组中只要有载波组需要关断，则接入网设备可以通过所有载波组对应的载波以组播方式、广播方式或单播方式向终端设备发送第一指示信息，也可以仅通过要关断的载波组对应的载波以组播方式、广播方式或单播方式向终端设备发送第一指示信息。载波组对应的载波可以理解为载波组中的所有载波或部分载波。
另一种情况下，第一指示信息可以包括关断指示和/或M个载波组的标识。可选的，第一指示信息可以包括关断指示以及需要关断的载波组的标识。
在此情况下，由于终端设备需要根据载波组的总数量确定一个载波组的标识所需比特，因此，接入网设备需要向终端设备发送第二指示信息。
如果所有载波组中只要有载波组需要关断，则接入网设备可以通过一个或多个载波以组播方式或广播方式向终端设备发送第一指示信息。
一种可能的实现中，第一指示信息的长度是可变的，接入网设备可以根据需要关断的载波组的标识和数量，确定第一指示信息的长度。
在第一指示信息包括关断指示的情况下，关断指示所需(或占用)的比特可以是预定义的。例如，可以通过1比特进行关断指示。例如，在“1”指示关断的情况下，第一指示信息中这个 比特的值为1。再例如，在“0”指示关断的情况下，第一指示信息中的比特的值为0。也可以通过2比特进行关断指示。例如，在“11”指示关断的情况下，第一指示信息中这个比特的值为1。再例如，在“00”指示关断的情况下，第一指示信息中的比特的值为0。还可以通过其他比特进行关断指示。
例如，在载波组的总数量为10，关断指示占用的比特数为1，以字节为单位进行指示的情况下，每个载波组的标识占用4比特，如果需要关断两个载波组，则第一指示信息需要9比特，第一指示信息可以使用2个字节。请参阅图11，图11是本申请实施例公开的一种第一指示信息的示意图。如图11中的a所示，第一个字节包括关断指示和第一个载波组的标识，剩余3个比特为预留比特，第二个字节包括第二个载波组的标识，剩余4个比特为预留比特。如图11中的b所示，第一个字节包括关断指示、第一个载波组的标识以及第二个载波组的标识的前3个比特，第二个字节包括第二个载波组的标识的第4个比特，剩余7个比特为预留比特。
再例如，在载波组的总数量为6，关断指示占用比特为1的情况下，每个载波组的标识需要3比特进行指示，如果需要关断两个载波组，则第一指示信息需要7比特，第一指示信息可以使用1个字节。请参阅图12，图12是本申请实施例公开的另一种第一指示信息的示意图。如图12所示，这个字节包括关断指示、第一个载波组的标识以及第二个载波组的标识，剩余1个比特为预留比特。
第一指示信息的长度也可以是固定不变地，即已经预定义了第一指示信息的长度但第一指示信息中的有效比特可以根据需要关断的载波组的标识和数量确定。例如，预定义的长度为2个字节，在载波组的总数量为10的情况下，每个载波组的标识需要4比特进行指示，如果需要关断两个载波组，第一指示信息需要10个比特，剩余6比特为预留比特。再例如，在载波组的总数量为6的情况下，每个载波组的标识需要3比特进行指示，如果需要关断两个载波组，第一指示信息需要8个比特，剩余10比特为预留比特。
上面是以第一指示信息包括关断指示进行说明的，不包括关断指示的类似，在此不再赘述。
第一指示信息可以隐式地指示上述关断指示。
一种情况下，在第一指示信息通过特定时频资源进行传输的情况下，第一指示信息可以指示关断指示。换句话说，关断指示与时频资源有对应关系。
在此情况下，由于终端设备需要根据载波组的总数量确定一个载波组的标识所需比特，因此，接入网设备需要向终端设备发送第二指示信息。
在另一种情况下，第一指示信息可以包括标志位以及M个载波组的标识。在第一指示信息包括这个标志位的情况下，第一指示信息可以包括关断指示。
第一指示信息可以携带在***消息中。具体地，接入网设备可以向终端设备发送***消息，***消息可以包括第一指示信息。***消息可以为***消息块(systeminformationblock，SIB)。例如，***消息可以为SIB1，也可以为SIB2，还可以为SIB3，还可以为其他SIB。***消息通过广播方式进行传输，因此，在第一指示信息携带在***消息中时，第一指示信息是通过广播方式进行传输的。
第一指示信息也可以携带在RRC信令中。具体地，接入网设备可以向终端设备发送RRC信令，RRC信令可以包括第一指示信息。RRC信令可以通过广播方式进行传输，因此，在第一指示信息携带在RRC信令中时，第一指示信息可以通过广播方式进行传输的。RRC信令也可以通过组播方式进行传输，因此，在第一指示信息携带在RRC信令中时，第一指示信息也可以通过组播方式进行传输的。RRC信令还可以通过单播方式进行传输，因此，在第一指示信息携带在RRC信令中时，第一指示信息还可以通过单播方式进行传输的。
第一指示信息还可以携带在MAC CE中。具体地，接入网设备可以向终端设备发送MAC CE，MAC CE可以包括第一指示信息。MAC CE可以通过广播方式进行传输，因此，在第一指示信息携带在MAC CE中时，第一指示信息可以通过广播方式进行传输的。MAC CE也可以通过组播方式进行传输，因此，在第一指示信息携带在MAC CE中时，第一指示信息也可以通过组播方式进行传输的。MAC CE还可以通过单播方式进行传输，因此，在第一指示信息携带在MAC CE中时，第一指示信息还可以通过单播方式进行传输的。
在第一指示信息携带在MAC CE中的情况下，接入网设备可以通过MAC子头(subheader)指示MAC CE的长度，以便终端设备可以根据MAC子头确定MAC CE的长度，进而接收MAC CE。
不同MAC CE具有对应的不同LCID，MAC子头中包含LCID用于区分不同的MAC CE。因此，上述MAC CE可以对应预定义的LCID。
第一指示信息也可以携带在DCI中。具体地，接入网设备可以向终端设备发送DCI，DCI可以包括第一指示信息。DCI可以通过广播方式进行传输，因此，在第一指示信息携带在DCI中时，第一指示信息可以通过广播方式进行传输的。DCI也可以通过组播方式进行传输，因此，在第一指示信息携带在DCI中时，第一指示信息也可以通过组播方式进行传输的。DCI还可以通过单播方式进行传输，因此，在第一指示信息携带在DCI中时，第一指示信息还可以通过单播方式进行传输的。
上述DCI可以为专门用于指示M个载波组关断的DCI，即专门用于传输第一指示信息的DCI，也可以复用其他DCI。在复用其他DCI指示M个载波组关断的情况下，可以在原有的DCI中增加相关的域来携带第一指示信息。在复用的这个DCI通过单播方式发送时，需要针对不同的终端设备分别进行发送。
同一载波组中的载波可以属于同一PA，即载波可以按照PA为粒度划分载波组，即属于同一PA的载波可以归类至一个载波组(即PA组)。
同一载波组中的载波也可以属于同一带宽，即载波可以按照带宽为粒度划分载波组，即属于同一带宽的载波可以归类至一个载波组(即带宽组)。NR中的工作带宽可以如表2所示：
表2
Figure PCTCN2022132646-appb-000003
LTE中的工作带宽可以如表3所示：
表3
工作带宽 上行工作带宽 下行工作带宽
1 1920MHz–1980MHz 2110MHz–2170MHz
2 1850MHz–1910MHz 1930MHz–1990MHz
3 1710MHz–1785MHz 1805MHz–1880MHz
4 1710MHz–1755MHz 2110MHz–2155MHz
5 824MHz–849MHz 869MHz–894MHz
6 830MHz–840MHz 875MHz–885MHz
7 2500MHz–2570MHz 2620MHz–2690MHz
8 880MHz–915MHz 925MHz–960MHz
9 1749.9MHz–1784.9MHz 1844.9MHz–1879.9MHz
10 1710MHz–1770MHz 2110MHz–2170MHz
11 1427.9MHz–1447.9MHz 1475.9MHz–1495.9MHz
12 699MHz–716MHz 729MHz–746MHz
13 777MHz–787MHz 746MHz–756MHz
14 788MHz–798MHz 758MHz–768MHz
应理解，表2是协议定义的NR工作带宽的部分，表3是协议定义的LTE工作带宽的部分。通过表2和表3可知，在不同制式中相同频段(或带宽)的编号相同，如表2中n8和表3中的8对应上行880MHz–915MHz、下行925MHz–960MHz，因此，不论哪种制式这个带宽的编号均为8。
应理解，载波还可以按照其他粒度划分载波组。例如，可以按照其他频域单元进行划分。
在协议规定每个载波对应的载波组的情况下，终端设备可以确定每个载波对应的载波组，因此，接入网设备不需要向终端设备指示每个载波对应的载波组。例如，在载波按照带宽进行划分载波组的情况下，由于协议已经规定了每个载波对应的带宽，因此，接入网设备不需要向终端设备指示每个载波对应的带宽。
在协议没有规定每个载波对应的载波组的情况下，接入网设备需要向终端设备指示每个载波对应的载波组。因此，接入网设备还可以向终端设备发送第三指示信息。相应地，终端设备接收来自接入网设备的第三指示信息。第三指示信息可以指示第一载波对应的载波组。第一载波可以为接入网设备上所有载波中的任一载波。
例如，在载波按照PA进行划分载波组的情况下，由于协议没有规定每个载波对应的PA，因此，接入网设备可以向终端设备发送第三指示信息。相应地，终端设备接收来自接入网设备的第三指示信息。第三指示信息可以指示第一载波对应的PA。
第三指示信息可以包括第一载波对应的载波组的标识。
在第三指示信息通过第一载波向终端设备发送的情况下，第三指示信息可以仅包括第一载波对应的载波组的标识。
第三指示信息还可以包括第一载波的标识。例如，第三指示信息可以为载波1和载波组1。
第三指示信息可以携带在***消息、RRC信令、MAC CE或DCI中。详细描述可以参考上面第一指示信息的相关信息。
接入网设备可以通过广播方式向终端设备发送第三指示信息。例如，由于各个载波上均需要广播SIB1，因此，接入网设备可以通过第一载波对应的SIB1向终端设备发送第三指示信息。接入网设备也可以通过组播方式向终端设备发送第三指示信息。接入网设备还可以通过单播方 式向终端设备发送第三指示信息。
接入网设备还可以通过广播方式和单播方式向终端设备发送第三指示信息。例如，对于使用CA的终端设备，接入网设备可以通过主载波对应的***消息向终端设备指示主载波对应的载波组，可以通过用于添加辅载波的RRC信令、MAC CE或DCI指示辅载波对应的载波组。
接入网设备可以在配置第一载波的时候向终端设备发送第三指示信息，也可以在配置第一载波之后向终端设备发送第三指示信息。
接入网设备还可以向终端设备发送配置信息。相应地，终端设备可以接收来自接入网设备的配置信息。配置信息可以用于配置候选主载波。候选主载波可以用于主站，也可以用于辅站。
接入网设备可以为每个终端设备配置一个候选主载波，这个候选主载波可以用于主站，也可以用于辅站，哪个先需要哪个可以先用。
接入网设备也可以为每个终端设备配置两个候选主载波，一个候选主载波用于主站，另一个候选主载波用于辅站。例如，接入网设备可以配置一个候选PCell，即候选主站主载波，以及配置一个候选PSCell，即候选辅站主载波。
上述配置信息可以包括候选主载波被激活的相关配置，如物理下行控制信道(physicaldownlinkcontrolchannel，PDCCH)配置、物理上行控制信道(physicaluplinkcontrolchannel，PUCCH)配置等。
702.终端设备关断M个载波组中的载波。
终端设备接收来自接入网设备的第一指示信息之后，可以关断M个载波组中的载波，即可以根据第一指示信息关断M个载波组中的载波。
在第一载波组包括多个载波的情况下，针对不同终端设备，这多个载波可以为不同RAT对应的主载波，也可以为不同RAT对应的辅载波，还可以为不同RAT对应的主载波和辅载波。终端设备可以根据第一指示信息关断第一载波组包括的载波。即不论第一载波组包括的载波属于哪个RAT、属于主站还是辅站、是主载波还是辅载波，终端设备都会关断第一载波组包括的载波。可见，用于关断M个载波组的指示信息可以不区分CA和DC。第一载波组为M个载波组中的任一载波组。
在第二载波为主站主载波的情况下，关断第二载波后，可以将配置信息配置的候选主载波或候选主站主载波激活为主载波，可以避免通过信令进行切换，从而可以减少业务中断时间，进而可以提高用户体验。第二载波为M个载波组包括的任一载波。
请参阅图13，图13是本申请实施例公开的一种按照PA划分载波组的示意图。如图13所示，接入网设备包括三个PA组，即PA1、PA2和PA3。PA1中的三个载波对应NR，PA2中的三个载波对应6G和NR，PA3中的两个载波对应6G。
终端设备2对应的主站和辅站均配置了多载波，即：MCG PCell和两个MCG SCell，以及SCG PSCell和一个SCG SCell。接入网设备在MCG上添加辅载波时，将PA1下的MCG SCell配置为候选主载波，即图中PA1下加粗的MCG SCell。假设接入网设备指示关断PA2，由于MCGPCell包含在PA2内，则当终端设备2接收到关断PA2的指示信息之后，可以立即或在预定义的时间后将候选载波激活为主载波，PA1下的MCG SCell生效为MCG PCell，由于PA2关断了，终端设备2在MCG上不存在其它载波，所以此时终端设备2上在MCG上仅有一个载波。如果在MCG上还有其它SCell的话，则在MCG依然为多载波，即SCell继续生效。
在第二载波为辅站主载波的情况下，关断第二载波后，可以将配置信息配置的候选主载波或候选辅站主载波激活为辅站主载波，可以避免通过信令进行变更，可以更快的实现辅站主载波的变更，以及可以减少传输的信令，进而可以节约传输资源。
以图13中的终端设备2为例进行说明，接入网设备可将PA1下的SCG SCell配置为候选辅站主载波。当PA2关断之后，终端设备2可以将PA1中的SCG SCell激活为SCG PSCell。
如图13中的终端设备1所示，第一指示信息指示关断PA2，对于终端设备1而言，PA2下既包含主站的辅载波，又包含辅站的辅载波，接入网设备可以仅通过某个载波发送第一指示信息，终端设备1收到第一指示信息后可以关断PA2中的三个载波。
终端设备关断M个载波组中的载波之后，可以向接入网设备发送反馈信息，也可以不向接入网设备发送反馈信息。
在第一指示信息携带在***消息和DCI中的情况下，终端设备关断M个载波组中的载波之后不向接入网设备反馈信息。接入网设备在向终端设备发送第一指示信息之后，可以立即关闭M个载波组中的载波，也可以等待一段时间之后再关闭M个载波组中的载波。
在第一指示信息携带在RRC信令，如RRC重配置消息，中的情况下，终端设备关断M个载波组中的载波之后，可以向接入网设备发送RRC重配置完成消息。接入网设备接收到来自终端设备的RRC重配置完成消息之后，可以关闭M个载波组中的载波。
在第一指示信息携带在MAC CE中的情况下，终端设备关断M个载波组中的载波之后，可以通过混合自动重传请求(hybridautomaticrepeatrequest，HARQ)向接入网设备发送确认(acknowledge，ACK)信息。接入网设备接收到来自终端设备的ACK信息之后，可以关闭M个载波组中的载波。
在M个载波组关断之后，接入网设备确定满足第二条件的情况下，可以向终端设备发送第四指示信息。相应地，终端设备接收来自接入网设备的第四指示信息。第四指示信息用于指示开启N个载波组，N为大于或等于1的整数。
终端设备可以开启N个载波组对应的载波。同理，终端设备开启N个载波组对应的载波之后，可以向接入网设备发送反馈信息，也可以不向接入网设备发送反馈信息。
开启N个载波组对应的载波之后，接入网设备可以通过重配置的方式向开启的载波上配置终端设备；也可以提高开启的载波的优先级，以便终端设备能够优先使用开启的载波。
第四指示信息的详细描述可以参考第一指示信息，区别在于，一个用于指示关断载波组，一个指示开启载波组。
接入网设备可以根据激活载波上的用户数、负载情况等信息，判断是否满足第二条件。例如，接入网设备可以判断是否存在各载波上的在线用户数大于或等于第一阈值的载波组，在判断至少一个载波组中各载波上的在线用户数大于或等于第一阈值的情况下，确定满足第二条件。再例如，接入网设备可以判断是否存在各载波上的数据量大于或等于第二阈值的载波组，在判断出至少一个载波组中各载波上的数据量大于或等于第二阈值的情况下，确定满足第二条件。再例如，接入网设备可以判断是否存在各载波上的RB利用率大于或等于第三阈值的载波组，在判断出至少一个载波组中存在各载波上的RB利用率大于或等于第三阈值的情况下，确定满足第二条件。
应理解，上面不同步骤或同一步骤中的不同情况、示例、实现方式可以单独执行，也可以相互组合来执行。
基于上述网络架构，请参阅图14，图14是本申请实施例公开的另一种通信方法的交互示意图。如图14所示，该通信方法可以包括以下步骤。
1401.接入网设备向终端设备发送用于指示第一载波对应的PA的第三指示信息。
相应地，终端设备接收来自接入网设备的用于指示第一载波对应的PA的第三指示信息。
第三指示信息包括第一载波对应的PA的标识。PA的标识可以为PA的索引(index)，也可以为其他可以唯一标识PA的信息。
1402.接入网设备向终端设备发送用于指示关断M个PA的第一指示信息。
相应地，终端设备接收来自接入网设备的用于指示关断M个PA的第一指示信息。
1403.终端设备关断M个PA中的载波。
终端设备接收来自接入网设备的第一指示信息之后，可以关断M个PA中的载波，即可以根据第一指示信息关断M个PA中的载波，同时还可以关断M个PA。由于PA的功耗较大，在关闭PA中的载波和PA的情况下，可以较大的降低功耗。
其中，步骤1401-步骤1403的详细描述可以参考图7对应的相关描述。
基于上述网络架构，请参阅图15，图15是本申请实施例公开的又一种通信方法的交互示意图。如图15所示，该通信方法可以包括以下步骤。
1501.接入网设备向终端设备发送用于指示关断M个带宽的第一指示信息。
相应地，终端设备接收来自接入网设备的用于指示关断M个带宽的第一指示信息。
1502.终端设备关断M个带宽中的载波。
终端设备接收来自接入网设备的第一指示信息之后，可以关断M个带宽中的载波，即可以根据第一指示信息关断M个带宽中的载波。
属于同一带宽的载波可以属于同一PA，也可以不属于同一PA。
在接入网设备为终端设备配置的多个载波属于M个带宽，且这多个带宽属于一个PA的情况下，终端设备还可以关断这个PA。由于PA的功耗较大，在关闭带宽中的载波和PA的情况下，可以较大的降低功耗。
举例说明，如图11所示，M个带宽包括带宽1和带宽2，带宽1包括PA2中的两个NR载波，带宽2包括PA2中一个6G载波。终端设备1和/或终端设备2接收到第一指示信息之后，可以关断这两个NR载波和这个6G载波。此外，由于PA2仅包括三个载波，且这三个载波均被关断了，因此，终端设备1和/或终端设备2可以进一步关闭PA2，可以进一步降低功耗。
其中，步骤1501-步骤1502的详细描述可以参考图7对应的相关描述。
基于上述网络架构，请参阅图16，图16是本申请实施例公开的又一种通信方法的交互示意图。如图16所示，该通信方法可以包括以下步骤。
1601.接入网设备向终端设备发送用于指示关断M个载波的第一指示信息。
相应地，终端设备接收来自接入网设备的用于指示关断M个载波的第一指示信息。
M个载波可以关联一个RAT，也可以关联多个RAT，M为大于或等于1的整数。详细描述可以参考步骤701下面的相关描述。
接入网设备向终端设备发送第二指示信息。相应地，终端设备接收来自接入网设备的第二指示信息。第二指示信息用于指示载波的总数量，总数量大于或等于M。详细描述可以参考步骤701下面的相关描述。
接入网设备向终端设备发送配置信息。相应地，终端设备接收来自接入网设备的配置信息。配置信息用于配置候选主载波。候选主载波用于主站或辅站。详细描述可以参考步骤701下面的相关描述。
第一指示信息包括M个载波的标识，详细描述可以参考步骤701下面的相关描述。
载波的标识可以为接入网设备对所有载波统一编号后的编号。所有载波可以包括不同RAT 的载波，也可以包括相同RAT的载波。
例如，接入网设备上共有8个载波，接入网设备可以将这8个载波统一编号为1～8。
第一指示信息携带在***消息、RRC信令、MAC CE或DCI中。MAC CE对应预定义的LCID。详细描述可以参考步骤701下面的相关描述。
接入网设备通过组播方式或广播方式发送第一指示信息。相应地，终端设备通过组播或广播方式接收来自接入网设备的第一指示信息。接入网设备通过单播方式发送第一指示信息。相应地，终端设备通过单播接收来自接入网设备的第一指示信息。详细描述可以参考步骤701下面的相关描述。
接入网设备向终端设备发送第三指示信息。相应地，终端设备接收来自接入网设备的第三指示信息。第三指示信息用于指示开启N个载波，N为大于或等于1的整数。详细描述可以参考步骤701下面的第四指示信息。
1602.终端设备关断M个载波。
