具体实施方式
下文中将结合附图对本申请的实施例进行说明。以下结合实施例附图对本申请进行描述，所举实例仅用于解释本申请，并非用于限定本申请的范围。
为了提高数据传输的可靠性，信道质量好的终端可以帮助信道质量差的终端发送数据包。这样，数据包既可以通过信道质量好的终端发送到基站，也可以通过信道质量差的终端发送到基站。基站会收到两份相同数据包，可靠性大大增加了。或者，为了提高数据传输的速率，信道质量好的终端可以帮助信道质量差的终端发送数据包。这样，对于上行数据包，数据包既可以通过信道质量好的终端发送到基站，也可以通过信道质量差的终端发送到基站。基站分别从多个终端收到数据包，接收到的数据包数量以及传输速率大大增加了。例如，终端1位于基站中心，其信道质量较好。终端2位于基站边缘，或者被障碍物遮挡，其信道质量较差。终端1和终端2分别与基站建立连接，并且，终端1和终端2之间建立连接，可以是有线连接，也可以是无线连接，例如：wifi连接、sidelink连接。终端2产生数据包后，转发给终端1。终端1可以协助终端2，将终端2的数据包转发到基站。终端1和终端2都分别将数据包发送给基站，从而基站分别从终端1和终端2收到数据包。图1是在一些情形下提供的一种终端和基站之间的通信示意图。如图1所示，两个终端可以处于同一个基站下，或者，两个终端可以处于不同基站下，即每个基站所连接的基站是不同的。
对于下行数据包，基站可以将数据包发送到信道质量好的终端，信道质量好的终端再转发给信道质量差的终端，基站也可以直接将数据包发送到信道质量差的终端。信道质量差的终端分别从基站和其他终端收到数据包，接收到的数据包的可靠性，或者数量以及传输速率大大增加了。
在基站下，多个终端都与基站建立连接，并且多个终端之间建立连接，一个终端的数据包经过另外一个终端转发，这种传输方法可以被称为终端聚合通信(Terminal Aggregator Communication，TAC)。需要说明的是，终端聚合通信也可以称为终端聚合传输。
其中，多个终端聚合传输既可以是重复发送，即多个终端在空口传输相同的数据包；也可以分别发送多个终端在空口传输不同的数据包。
在终端聚合传输方案中，产生数据包的终端或者数据包最终提交的目的终端，被称为anchor UE；而协助传输的终端，被称为non anchor UE。在anchor UE和non anchor UE接入了不同的基站的情况下，anchor UE接入的基站称为anchor基站，non anchor UE接入的基站称为non anchor基站。
在一实施例中，图2是本申请实施例提供的一种通信方法的流程图。本实施例可以由通信设备执行。其中，通信设备可以为第一通信节点，示例性地，第一通信节点可以为anchor UE，即用于生成数据包的节点。如图2所示，本实施例包括：S210。
S210、通过第二通信节点发送协议数据单元(Protocol Data Unit，PDU)数据。
其中，所述PDU数据，包括下述之一：基于复制功能相同的分组数据汇聚协议(Packet Data Convergence Protocol，PDCP)PDU；或基于分发功能不同的PDCP PDU。
其中，第二通信节点用于协助第一通信节点进行数据传输的节点。示例性地，假设第一通信节点为anchor UE，相应的，第二通信节点为non anchor UE。第三通信节点指的是基站。在实施例中，在第一通信节点和第二通信节点处于单个基站的场景下，第一通信节点和第二通信节点接入同一个第三通信节点(即基站)；在第一通信节点和第二通信节点处于多个基站的场景下，即第一通信节点和第二通信节点位于不同的基站，并且，第一通信节点为anchor UE，以及第二通信节点为non anchor UE，则第一通信节点所接入的第三通信节点为anchor基站，第二通信节点所接入的其它第三通信节点为non anchor基站。可以理解为，anchor基站指的是支持控制数据产生，并处理功能的基站；non anchor基站指的是支持协助传输以及数据转发的基站。
在实施例中，针对单播传输场景下，对于一个业务，第三通信节点与第一通信节点以及第二通信节点之间通过建立专有信道(比如，逻辑信道，传输信道等)进行数据传输；针对组播传输场景下，对于一个业务，第三通信节点与多个第一通信节点或者多个第二通信节点之间通过建立公共信道(比如，逻辑信道，传输信道等)进行数据传输。在一实施例中，在单播传输场景，并且单个第三通信节点(即单基站)的场景下，第一通信节点将PDU数据发送至第二通信节点，以使第二通信节点对PDU数据进行处理，并转发至第三通信节点；或者，第二通信节点直接将PDU数据发送至第三通信节点。在一实施例中，在单播传输场景，并且多基站的场景下，并且，第一通信节点为anchor UE，以及第二通信节点为non anchor UE，则第一通信节点接入的第三通信节点为anchor基站，第二通信节点接入的其它第三通信节点为non anchor基站，第一通信节点将PDU数据直接发送至anchor基站；或者，第一通信节点将PDU数据发送至第二通信节点，第二通信节点对PDU数据进行数据，并转发至non anchor基站，并通过non anchor基 站将PDU数据转发至anchor基站。
在一实施例中，所述第一通信节点和所述第二通信节点均接入第三通信节点；所述第一通信节点和所述第三通信节点之间建立服务数据适配协议(Service Data Adaptation Protocol,SDAP)、PDCP、无线链路层控制协议(Radio Link Control，RLC)和介质访问控制(Medium Access Control，MAC)层；所述第二通信节点和所述第三通信节点之间建立RLC和MAC层。在一实施例中，在第一通信节点和第二通信节点处于单基站的场景中，第一通信节点和第二通信节点均接入同一个第三通信节点，在Uu接口，第一通信节点和第三通信节点之间建立SDAP、PDCP、RLC和MAC层；在Uu接口，第二通信节点和第三通信节点建立RLC和MAC层。如果支持SideLink传输，在PC5接口，第一通信节点和第二通信节点分别建立RLC层和MAC层。

在一实施例中，所述第一通信节点接入第三通信节点，且所述第二通信节点接入其它第三通信节点；所述通过第二通信节点向第三通信节点发送PDU数据，包括：通过第二通信节点将PDU数据发送至所述其它第三通信节点，以通过所述其它第三通信节点将所述PDU数据转发至所述第三通信节点。在实施例中，在单播传输场景，并且即多基站的场景下，第一通信节点为anchor UE，以及第二通信节点为non anchor UE，则第一通信节点接入的第三通信节点为anchor基站，第二通信节点接入的其它第三通信节点为non anchor基站，第一通信节点将PDU数据发送至第二通信节点，并通过第二通信节点发送至其它第三通信节点，以通过其它第三通信节点将PDU数据转发至第三通信节点。
在一实施例中，所述第一通信节点、所述第二通信节点和所述第三通信节点处于组播传输场景，所述第三通信节点通过RRC消息为所述第一通信节点和所述第二通信节点配置相同的无线网络临时标识(Radio Network Temporary Identifier，RNTI)以及物理下行控制信道(Physical Downlink Control Channel，PDCCH)资源。在实施例中，为了支持组播场景，第三通信节点和/或其它第三通信节点为第一通信节点和第二通信节点通过RRC消息配置相同的RNTi，以及相同的PDCCH资源。第一通信节点和第二通信节点在相同的PDCCH资源上，采用相同RNTI监听相同的PDCCH。如果PDCCH调度一个数据包，第一通信节点和第二通信节点均可以接收到。
在一实施例中，在所述通过第二通信节点发送PDU数据之前，还包括：向第三通信节点发送第一信道状态；其中，第一信道状态包括下述之一：第一通信节点测量得到的终端连接信道状态；或第二通信节点测量得到的终端连接信道状态。在实施例中，第一信道状态用于确定第三通信节点是否可以开始终端聚合传输。并且，第一信道状态指的是由终端直接测量并上报至对应的基站的信道状态。示例性地，第一信道状态可以由第一通信节点测量并直接上报至对应的第三通信节点；也可以由第二通信节点测量并直接上报至对应的其它第三通信节点。示例性地，第一通信节点为anchor UE，以及第二通信节点为non anchor UE，则第一通信节点接入的第三通信节点为anchor基站，第二通信节点接入的其它第三通信节点为non anchor基站。在实施例中，第一信道状态可以包括终端连接信道状态，也可以包括Uu接口的信道状态。其中，终端连接信道状态指的是终端之间连接的信道状态，可以是第一通信节点测量得到的终端连接信道状态，也可以是第二通信节点测量得到的终端连接信道状态。在实施例中，终端连接信道状态可以包括：SideLink连接、WiFi连接、蓝牙连接的信道状态。可以理解为，第一通信节点或第二通信节点测量SideLink信道得到的终端连接信道状态，也可以为第一通信节点或第二通信节点测量WiFi信道得到的终端连接信道状态；也可以为第一通信节点或第二通信节点测量蓝牙信道得到的终端连接信道状态。Uu接口的信道状态，指的是终端和基站之间接口的信道状态，可以为第一通信节点和第二通信节点分别与第三通信节点之间接口的信道状态，也可以为第一通信节点和第二通信节点分别与其它第三通信节点之间接口的信道状态。
在一实施例中，所述第一信道状态所对应的承载信令格式包括下述之一：信道指示位和信道状态；或信道标识和信道状态；或信道标识、频域标识和信道状态；或信道指示位、频域标识和信道状态；或信道指示位、信道标识和信道状态；或信道指示位、信道标识、频域标识和信道状态。在实施例中，第一通信节点或第二通信节点可以通过对应的承载信令将第一信道状态上报至对应的第三通信节点或其它 第三通信节点。示例性地，承载信令可以为MAC CE信令。在实施例中，MAC CE信令的格式可以包括：信道指示位和信道状态，也可以为信道标识和信道状态，也可以为信道标识、频域标识和信道状态，也可以为信道指示位、频域标识和信道状态，也可以为信道指示位、信道标识和信道状态，也可以为信道指示位、信道标识、频域标识和信道状态。
在一实施例中，应用于第一通信节点的通信方法，还包括：接收第二通信节点发送的第二信道状态；将所述第二信道状态转发至第三通信节点。在实施例中，第二信道状态用于确定第三通信节点是否可以开始终端聚合传输。并且，第二信道状态可以由第二通信节点测量并通过第一通信节点上报至对应的第三通信节点。示例性地，第一通信节点为本端UE，第二通信节点为对端UE，并且，第一通信节点为anchor UE，以及第二通信节点为non anchor UE，则第一通信节点接入的第三通信节点为anchor基站，第二通信节点接入的其它第三通信节点为non anchor基站，并且，对端UE测量得到其所接入的其它第三通信节点的信道状态，作为第二信道状态，然后将第二信道状态发送至所连接的本端UE，以通过本端UE将第二信道状态发送至所连接的第三通信节点。在实施例中，第二信道状态指的是对端UE与所接入基站的信道状态。示例性地，假设第二通信节点为对端UE，所接入的基站为其它第三通信节点，则第二信道状态包括对端UE测量其它第三通信节点得到的信道状态。当然，在实际通信过程中，第二信道状态也可以包括：本端UE测量其接入基站的信道状态，示例性地，假设第一通信节点为本端UE，所接入的基站为第三通信节点，则本端UE测量通信节点的信道状态。

在一实施例中，在所述通过第二通信节点发送PDU数据之前，还包括：接收第三通信节点预先配置的信道状态上报触发条件。在实施例中，在第一通信节点或第二通信节点上报自身的信道状态(即第一信道状态)，或者其他UE的信道状态(即第二信道状态)，会消耗空口资源。可以理解为，为了减少空口资源的浪费，在第一通信节点或第二通信节点满足信道状态上报触发条件时，上报对应的信道状态。当然，在第一通信节点和第二通信节点的触发条件可以是不同的，可以由对应的第三通信节点配置信道状态上报触发条件。

在一实施例中，在所述通过第二通信节点发送PDU数据之前，还包括：接收第三通信节点发送的终端聚合通信TAC激活指令或TAC去激活指令；根据所述TAC激活指令激活TAC，或者，根据所述TAC去激活指令去激活TAC。在实施例中，第一通信节点或第二通信节点的信道状态是变化的，在信道状态不符合终端聚合传输的情况下，基站可以选择是否进行终端聚合传输，例如：当anchor UE的信道恶化，基站可以激活终端聚合传输；但是当non anchor UE的信道恶化，基站需要去激活终端聚合传输。
在一实施例中，应用于第一通信节点的通信方法，还包括：向第二通信节点发送TAC激活指令或TAC去激活指令，以使第二通信节点根据所述TAC激活指令开启TAC，或者，根据所述TAC去激活指令结束TAC。

在一实施例中，以第一通信节点为anchor UE，第二通信节点为non anchor UE，以及第三通信节点为基站(记为gNB)为例，对用户面的架构进行说明。在终端聚合传输，多个终端都与基站建立连接，并且多个终端之间建立连接，一个终端的数据包经过另外一个终端转发。其用户面架构如下：
其一，针对单播传输场景：
对于单播传输方案，也就是，对于一个业务，基站和UE之间是通过建立专有的信道(例如：逻辑信道，传输信道等)传输数据的。
图5是本申请实施例提供的一种单播单基站场景下的交互示意图。如图5所示，对于单基站的场景，anchor UE和non anchor UE都接入同一个基站。
在Uu接口，anchor UE和基站建立SDAP层,PDCP层,RLC层和MAC层。
在Uu接口，non anchor UE和基站建立RLC层和MAC层。
如果支持SideLink传输，在PC5接口，non anchor UE和anchor UE建立分别RLC层和MAC层。
对于单基站场景下的上行传输过程包括：
anchor UE将PDCP PDU(基于复制功能相同的PDCP PDU，或基于分发功能不同的PDCP PDU)通过Uu接口发送给基站。
anchor UE将PDCP PDU(基于复制功能相同的PDCP PDU，或基于分发功能不同的PDCP PDU)发送给non anchor UE，如果支持SideLink传输，通过PC5接口发送给non anchor UE。
non anchor UE会将从anchor UE接收到的PDCP PDU经过RLC和MAC的处理，将其转发给基站。
基站在PDCP层，对从non anchor UE和anchor UE接收到的数据进行重排序等处理。然后提交给SDAP层。
对于单基站场景下的下行传输过程包括：
基站将PDCP PDU(基于复制功能相同的PDCP PDU，或基于分发功能不同的PDCP PDU)通过Uu接口发送给anchor UE。
基站将PDCP PDU(基于复制功能相同的PDCP PDU，或基于分发功能不同的PDCP PDU)通过Uu接口发送给non anchor UE。
non anchor UE将从基站接收到的数据包，转发给anchor UE，如果支持sidelink，通过PC5接口将接收到的数据转发给anchor UE。
anchor UE在PDCP层，对从non anchor UE和anchor基站接收到的数据进行重排序等处理。然后提交给SDAP层。
图6是本申请实施例提供的一种单播多基站场景下的交互示意图。如图6所示，对于多基站的场景，anchor基站指的是支持控制数据产生、处理的功能的基站，也是anchor UE接入的基站；non anchor基站指的是支持协助传输、支持数据转发的基站，也是non anchor UE接入的基站。
在Uu接口，anchor UE和anchor基站建立SDAP层,PDCP层,RLC层和MAC层。
在Uu接口，non anchor UE和non anchor基站建立RLC层和MAC层。
如果支持SideLink传输，在PC5接口，non anchor UE和anchor UE建立分别RLC层和MAC层。
在Xn或X2接口上，non anchor基站和anchor基站分别建立Xn或X2接口的协议站。
对于多基站场景下的上行传输过程包括：
anchor UE将PDCP PDU(基于复制功能相同的PDCP PDU，或基于分发功能不同的PDCP PDU)通过Uu接口发送给anchor基站。
anchor UE将PDCP PDU(基于复制功能相同的PDCP PDU，或基于分发功能不同的PDCP PDU)发送给non anchor UE，如果支持sidelink传输，通过PC5接口发送给non anchor UE。
non anchor UE会将从anchor UE接收到的PDCP PDU进过RLC和MAC的处理，将其转发给non anchor基站。
non anchor基站通过Xn或X2接口将接收到的PDCP PDU转发给anchor基站。
anchor基站在PDCP层，对从non anchor基站和anchor UE接收到的数据进行重排序等处理。然后提交给SDAP层。
对于多基站场景下的下行传输过程包括：
anchor基站将PDCP PDU(基于复制功能相同的PDCP PDU，或基于分发功能不同的PDCP PDU)通过Uu接口发送给anchor UE。
anchor基站将PDCP PDU(基于复制功能相同的PDCP PDU，或基于分发功能不同的PDCP PDU)通过Xn或X2接口发送给non anchor基站。
non anchor基站会将从anchor基站接收到的数据进过RLC和MAC的处理，将PDCP PDU转发给non anchor UE。
non anchor UE将从non anchor基站接收到的数据包，转发给anchor UE，如果支持sidelink，通过PC5接口将接收到的数据转发给anchor UE。
anchor UE在PDCP层，对从non anchor UE和anchor基站接收到的数据进行重排序等处理。然后提交给SDAP层。
其二，针对组播传输场景：
图7是本申请实施例提供的一种组播场景下的交互示意图。如图7所示，对于组播传输方案，也就是，对于一个业务，基站和多个UE之间是通过建立公共的信道(例如：逻辑信道，传输信道等)传输数据的。
在Uu接口，anchor UE和基站建立SDAP,PDCP,RLC和MAC层。
在Uu接口，non anchor UE和基站建立RLC和MAC层。
如果支持SideLink传输，在PC5接口，non anchor UE和anchor UE建立分别RLC和MAC层。
对于组播传输场景下的下行传输过程包括：
基站发送的数据，anchor UE和non anchor UE同时接收。
如果支持SideLink传输，non anchor UE会将从基站接收到的数据进过MAC和RLC的处理，将PDCP PDU转发给anchor UE。
non anchor UE在PDCP层，对从基站和non anchor UE接收到的数据进行重排序等处理。然后提交给SDAP层。
为了支持组播，基站给anchor UE和non anchor UE通过RRC消息配置相同的RNT I，以及相同的PDCCH资源。
anchor UE和non anch or UE在相同的PDCCH资源上，采用相同RNT I监听相同的PDCCH。如果PDCCH调度一个数据包，anchor UE和non anchor UE都能接收到。
在一实施例中，以第一通信节点为本端UE，并且，本端UE为anchor UE，第二通信节点为对端UE，并且，对端UE为non anchor UE，以及第三通信节点为基站(记为gNB)为例，对信道状态的传输过程进行说明。在实施例中，基站可以根据UE的信道状态选择是否开始终端聚合传输，基站需要考虑的因素：基站和non-anchor UE之间的信道状态、基站和anchor UE之间的信道状态以及non-anchor UE和anchor UE之间的信道状态。所以，anchor UE和non anchor UE的信道状态要上报给基站，供基站参考。图8是本申请实施例提供的一种信道状态的交互示意图。如图8所示，信道状态的传输过程包括S810-S830。
S810、non anchor UE向anchor UE上报第二信道状态。
S820、anchor UE向gNB直接上报第一信道状态或转发第二信道状态。
S830、non anchor UE向gNB上报第一信道状态。
需要说明的是，可以由anchor UE或non anchor UE直接将第一信道状态上报至gNB；也可以由non anchor UE将第二信道状态上报至anchor UE，并由anchor UE将第二信道状态转发至gNB。
示例1：对第一信道状态的交互过程进行说明：
本端UE和对端UE之间的连接可能是SideLink连接、WiFi连接、蓝牙连接等无线连接。本端UE或对端UE上报终端之间连接的信道状态。本端UE和对端UE得到的终端之间连接的信道状态。那么，本端UE和对端UE可将终端之间连接的信道状态，上报给基站。其中，终端之间连接的信道状态可以是UE测量得到的SideLink连接、WiFi连接、蓝牙连接的信道状态，也可以是参与聚合传输的对端UE测量下行信号得到的SideLink连接、WiFi连接、蓝牙连接的信道状态等。上报的测量结果可以是MAC CE，其格式为：

示例2：对第二信道状态的交互过程进行说明：
本端UE上报对端UE的信道状态。对端UE测量得到在其接入基站的信道状态。那么，对端UE可将在其接入基站的信道状态，转发给本端UE，并由本端UE上报给其接入的基站。其中，对端UE可通过终端连接上通过MAC CE或其他数据包将在其接入基站的信道状态上报给本端UE，本端UE可在Uu接口上通过MAC CE或其他数据包将其上报到在其接入基站。MAC CE或其他数据包的其格式为：

本端UE也可测量其接入的基站下行信号得到Uu的信道状态。那么，本端UE可将对端UE的Uu信道状态和自身的Uu信道状态的信道状态，上报给基站。如果上报的MAC CE或其他数据包，同时包含对端UE的和自身的Uu信道状态信道状态，本端UE将自身的Uu的信道状态可位于MAC CE的第一列(如表7所示)，Uu指示位(例如：0)，也可不携带Uu指示位，默认为是Uu的信道状态。对端UE的信道状态可按照上述格式携带，位于后面的列。
这里，信道指示位可以有一个或多个比特标识，例如：1为SideLink或WiFi或蓝牙，0为Uu。
信道标识可以用于标识UE和UE之间的连接索引，例如anchor UE与non anchor UE1的信道为信道标识＝1，anchor UE与non anchor UE2的信道为信道标识＝2。信道标识可以用于标识non anchor UE或anchor UE，可以是non anchor UE或anchor UE的目标标识，也可以是UE索引。这里的信道标识，可以由基站配置的。
Uu指示位可以有一个比特标识，例如：1为non anchor基站的Uu，0为anchor基站的Uu。或者多个比特指示，例如：01为SideLink或WiFi或蓝牙，10为non anchor基站的Uu。
Uu标识可以用于标识基站和UE之间的通信索引，例如：基站1与UE1的Uu为Uu标识＝1，基站1与UE 2的Uu为Uu标识＝2。Uu标识也可以是UE索引。这里的Uu标识，可以由基站配置的。
在一实施例中，如果UE总是上报信道状态，或者上报其他UE的信道状态，会消耗空口资源。为了减少空口资源的没必要的消耗，在UE满足一定的信道状态上报触发条件的情况下，上报信道状态。同时，anchor UE和non anchorUE的触发条件是不同的，可以由基站配置决定其触发条件。
示例性地，触发条件包括下述之一：
条件一：UE的信道质量或接收信号强度低于一定门限值(即第一信道质量门限值或第一接收信号强度门限值)。基站可以广播或者RRC配置关于建立终端聚合传输或者终端链接的信道质量的门限值。UE进行判断，如果UE的信道质量或接收信号强度低于该门限值，也就是该UE的信道状态不太好，anchor UE就可以建立终端聚合传输或者终端链接，non anchor UE不能进行有效的协助传输。这里的信道质量为UE测量到的基站下行信号的信道质量，包括：CQI等。接收信号强度为UE测量到的UE接收到基站的信道强度，包括，RSRP，RSRQ等。或
条件二：UE的信道质量或接收信号强度高于一定门限值(即第二信道质量门限值或第二接收信号强度门限值)。基站可以广播或者RRC配置了关于建立终端聚合传输或者终端链接的信道质量的门限值。UE进行判断，如果UE的信道质量或接收信号强度高于该门限值，也就是该UE的信道状态较好，anchor UE可以满足业务要求的速率了，就不需要建立终端聚合传输或者终端链接，non anchor UE可以进行有效的协助传输。这里的信道质量为UE测量到的基站下行信号的信道质量，包括：CQI等。接收信号强度为UE测量到的UE接收到基站的信道强度，包括，RSRP，RSRQ等。或
条件三：UE的业务丢包率大于某个门限(即丢包率门限值)。基站广播或者RRC配置建立终端聚合传输或者终端链接的业务丢包率的门限，例如：该业务HARQ丢包率或ARQ丢包率的门限。UE进行判断，如果UE建立的业务的业务丢包率大于该门限值，例如：UE的业务的HARQ丢包率或ARQ丢包率值大于该门限，也就是该终端的业务丢包率较高，anchor UE需要建立终端聚合或者终端链接，或者non anchor UE不能提供有效的协助传输。或
条件四：UE的重传次数大于某个门限(即重传次数门限值)。基站广播或者RRC配置建立终端聚合传输或者终端链接的重传次数的门限，例如：该业务HARQ重传次数或ARQ重传次数的门限。UE进行判断，如果UE建立的业务的重传次数大于该门限值，例如：UE的业务的HARQ重传次数或ARQ重传次数大于该门限，也就是该终端的业务重传次数较高，传输时延较大，anchor UE需要建立终端聚合或者终端链接，或者non anchor UE不能提供有效的协助传输。
上述触发条件可以单独使用，可以组合使用。
在一实施例中，由于UE的信道状态是变化的，在UE的信道状态不符合终端聚合传输的情况下，基站可以选择是否进行终端聚合传输，例如：在anchor UE的信道恶化的情况下，基站可以激活终端聚合传输；在non anchor UE的信道恶化的情况下，基站需要去激活终端聚合传输。
以第一通信节点为anchor UE，第二通信节点为non anchor UE，以及第三通信节点为基站(记为gNB)为例，对TAC激活指令(简称为激活指令)或去激活指令(简称为去激活指令)的传输过程进行说明。
示例1：图9是本申请实施例提供的一种基站和UE之间TAC激活指令或TAC去激活指令的交互示意图。如图9所示，本实施例包括S910-S920。
S910、接收gNB发送的TAC激活指令或TAC去激活指令。
S920、向gNB反馈TAC激活或TAC去激活确认消息。
在实施例中，基站给UE下发激活指令，激活终端聚合。激活命令可以携带TAC激活指示(也可以称为终端聚合激活指示)，激活业务标识，激活UE标识，激活终端连接。示例性地，激活连接可以包括：SideLink或WiFi或蓝牙等。UE接收到后，开启终端聚合传输，对相应的业务或相应的UE之间的所有业务开始在终端和终端之间的连接上发送或接收数据。
TAC激活指令可以是MAC CE，其格式为：TAC激活指示。例如：表14是本申请实施例提供的一种携带TAC激活指令的MAC CE格式的示意表，如表14所示，MAC CE格式包括TAC激活指示。

去激活命令可以是MAC CE，其格式为：TAC去激活指示，例如：表20是本申请实施例提供的一种携带TAC去激活指令的MAC CE格式的示意表，如表20所示，MAC CE格式包括TAC去激活指示。
