步骤S102，根据所述协作承载配置信息，与所述目标协作用户设备协作以与接入网设备进行通信。
在本发明实施例中，主用户设备在进行上行数据传输时，可以根据接收到的协作承载配置信息，将上行数据分为上行协作数据和上行非协作数据。主用户设备可以将上行协作数据发送至目标协作用户设备，由目标协作用户设备将上行协作数据发送至接入网设备；主用户设备可以将上行非协作数据直接发送至接入网设备。接入网设备可以将接收到的上行协作数据以及上行非协作数据发送至核心网设备。

例如，主用户设备A与接入网设备进行通信时，主用户设备A将上行数据0分为上行非协作数据1以及上行协作数据2。主用户设备A将上行非协作数据1发送至接入网设备，将上行协作数据2发送至目标协作用户设备B。目标协作用户设备B将上行协作数据2发送至接入网设备。接入网设备将上行非协作数据1以及上行协作数据2发送至核心网设备。核心网设备将下行非协作数据1’以及下行协作数据2’发送至接入网设备。接入网设备将下行非协作数据1’发送给主用户设备A，将下行协作数据2’发送给目标协作用户设备B。目标协作用户设备将下行协作数据2’发送给主用户设备A。此时，主用户设备A接收到下行非协作数据1’以及下行协作数据2’，
在具体实施中，主用户设备在接收协作承载配置信息之前，还可以上报辅助信息，辅助信息可以用于请求协作传输。主用户设备可以将辅助信息上报至接入网设备，经由接入网设备上报至核心网设备。核心网设备在接收到辅助信息之后，可以生成与辅助信息对应的协作承载配置信息。
主用户设备可以直接与接入网设备进行通信，以将辅助信息上报至接入网设备。主用户设备也可以将辅助信息发送至目标协作用户设备，由目标协作用户设备向接入网设备上报辅助信息。主用户设备可以将辅助信息上报至接入网设备，并将辅助信息发送至目标协作用户设备，这种情况下，接入网设备可以接收到主用户设备发送的辅助信息以及目标协作用户设备发送的辅助信息。
在本发明实施例中，辅助信息可以包括以下任一项或者多项：协作数据传输请求、请求协作传输的业务标识、请求协作传输的数据的服务质量参数以及请求协作传输的数据方向。
协作数据传输请求可以用于指示请求进行协作数据传输。在具体实施中，协作数据传输请求可以通过一个预先设置的第二消息的消息名称来指示。例如，第二消息的消息名称为协作数据传输请求信息。
请求协作传输的业务标识可以为数据资源承载(Data Radio Bearer，DRB)标识(id)、逻辑信道(Logic Channel，LCH)id、服务质量流(QoS flow)id等。

请求协作传输的数据方向可以为上行，也可以为下行，或者为上行和下行。
在具体实施中，若由主用户设备上报辅助信息，则主用户设备可以通过第二消息，将辅助信息发送至接入网设备。第二消息可以为无线资源控制(Radio Resource Control，RRC)消息，也可以为媒体接入控制(Media Address Control，MAC)元素(Control Element，CE)，还可以为上行行控制信息(UPlink Control Information，UCI)等。
若由目标协作用户设备上报辅助信息，则目标协作用户设备可以通过第三消息，将辅助信息发送至接入网设备。第三消息可以为RRC消息，也可以为MAC CE，还可以为UCI等。
在具体实施中，主用户设备在上报辅助信息之前，或接入网设备下发协作承载配置信息之前，还可以先确定目标协作用户设备。
在本发明实施例中，主用户设备可以先获取候选协作用户设备。之后，主用户设备可以从候选协作用户设备中选择目标协作用户设备。
在从候选协作用户设备中选择目标协作用户设备时，可以选择与主设备之间的信号质量达到预设阈值的候选协作用户设备作为目标协作用户设备；也可以选择当前负荷值低于预设负荷值的候选协作用户设备作为目标协作用户设备；还可以同时选择与主设备之间的信号质量达到预设阈值且当前负荷低于预设负荷值的候选协作用户设备作为目标协作用户设备。
在本发明实施例中，主用户设备可以选择与其之间的信号质量最好的候选协作用户设备作为目标协作用户设备，或者选择当前负荷最小的候选协作用户设备作为目标协作用户设备，或者同时选择与其之间的信号质量最好且当前负荷最小的候选协作用户设备作为目标协作用户设备。

协作用户设备信息对应的候选协作用户设备可以为协作业务对应的可选择的协作用户设备，协作业务可以是指通过协作方式进行数据传输的一个或者多个业务。
主用户设备在接收到协作用户设备信息之后，可以根据上述的预设的第一条件，从中选择一个或者多个候选协作用户设备作为目标协作用户设备。主用户设备在确定了目标协作用户设备之后，可以将目标协作用户设备的标识信息上报至接入网设备。目标协作用户设备的标识信息可以为目标协作用户设备的5G-TMSI信息，或者为目标协作用户设备的C-RNTI信息等。
例如，主用户设备在接收到协作用户设备信息之后，从中选择候选协作用户设备1作为目标协作用户设备。主用户设备将候选协作用户设备1的标识“1”发送至接入网设备。
在具体实施中，主用户设备可以通过第一消息，将目标协作用户设备的标识信息发送至接入网设备。第一消息可以为无线资源控制(Radio Resource Control，RRC)消息，也可以为媒体接入控制(Media Address Control，MAC)元素(Control Element，CE)，还可以为下行控制信息(UPlink Control Information，UCI)等。
在本发明实施例中，还存在主用户设备未接收到核心网设备发送的协作用户设备信息的应用场景。在这种情形下，主用户设备可以选择其他用户设备作为目标协作用户设备，其他用户设备可以为与主用户设备地理位置相邻的用户设备。
由此可见，通过接收协作承载配置信息，使得主用户设备能够与目标协作用户设备进行协作通信，从而实现协作数据的发送和接收，提高数据传输速率。

接入网设备还可以将协作承载配置信息分别下发至主用户设备以及目标协作用户设备。目标协作用户设备在接收到协作承载配置信息之后，将接收到的协作承载配置信息发送至主用户设备，提高数据传输的可靠性。
在本发明实施例中，协作承载配置信息所包括的内容可以对应参照上述步骤S101～步骤S102对应的实施例，此处不做赘述。此外，主用户设备接收到协作承载配置信息之后所执行的操作也可以对应参照步骤S102。
