本申请主张在2022年11月03日在中国提交的中国专利申请No.202211372013.2的优先权，其全部内容通过引用包含于此。
技术领域
本申请属于通信技术领域，具体涉及一种终端聚合建立方法、配置方法、装置及通信设备。
背景技术
无线通信系统中的中继(Relay)技术，就是在基站与终端之间增加了一个或多个中继节点，负责对无线信号进行一次或者多次的转发，即无线信号要经过多跳才能到达终端。
无线中继技术不仅可用于扩展小区覆盖，弥补小区覆盖盲点，同时也可通过空间资源复用提升小区容量。对于室内覆盖，Relay技术也可起到克服穿透损耗，提升室内覆盖质量的作用。以较简单的两跳中继为例，无线中继就是将一个基站—终端链路分割为基站—中继站和中继站—终端两个链路，从而有机会将一个质量较差的链路替换为两个质量较好的链路，以获得更高的链路容量及更好的覆盖。
目前长期演进(Long Term Evolution，LTE)中已经支持的Relay为终端到网络中继(UE-to-Network relay)，即Relay一端连接终端(User Equipment，UE)，一端连接网络侧。跟Relay连接的UE，叫做远端UE(Remote UE)。
新空口(New Radio，NR)也将研究如何支持UE-to-Network Relay机制，典型场景如图1所示。图中是一个典型的UE-to-Network的场景，Remote UE需要与网络侧传输数据，但由于覆盖不佳，找到Relay UE为其中转，其中Relay UE与基站之间是Uu接口，Relay UE和Remote UE之间是旁链路(sidelink)PC5接口。一般来说，Relay UE是开放的，可以为任何Remote UE服务。
旁路链路中继架构属于多路径场景中的一种情形，在多路径场景中如何建立多终端聚合的多路径传输是亟待解决的问题。
