Description

一种协作集建立的方法和装置 技术领域
本文涉及但不限于无线通信技术领域，尤其涉及的是一种协作集建立的方法和装置。
背景技术
在无线蜂窝通信***中，处于小区边缘的用户设备或者无宏小区覆盖的用户设备，可能需要通过用户设备的协助才能接入无线网络，以维持正常的语音和数据业务或者获得更好的服务质量。另一方面，用户设备渗透率的发展规律决定了高版本用户设备推出的初期在用户设备总量中占比不多，甚至占比偏小，大量的低版本用户设备不仅难以从高版本的网络中获益，并且会使得高版本网络的高性能无法被充分利用，这个问题即使在低版本用户设备完全退出市场后也依然会在不同子版本的高版本用户设备间存在。
如图1所示，多用户协作通信(Multiple User Cooperative Communication)是一种在无线通信***中通过多个用户设备(User Equipment，简称UE)协作达到提升某个UE吞吐量的技术。具体的，协作组中的两个UE，一个是协作用户设备(Cooperate User Equipment，简称C-UE)，另一个是受益用户设备(Benefit User Equipment，简称B-UE)。协作用户设备作为基站与受益用户设备之间的数据中转者，转发基站与受益用户设备之间的无线业务数据。基站与受益用户设备之间的无线链路定义为直连链路，该链路带宽相对较小，数据速率较低。基站与协作用户设备之间的无线链路定义为回传链路，该链路带宽较大，数据速率较高。协作用户设备与受益用户设备之间的无线链路定义为接入链路，由于受协作用户设备服务的受益用户设备数量一般并不多，并且协作用户设备与受益用户设备之间的距离较近，链路质量好，因此接入链路的数据速率通常高于直连链路。
由于协作集的建立过程涉及到基站、协作用户设备和受益用户设备三者，因此，多个网元之间的信息交互导致协作集的建立时延较大。
