本公开涉及通信领域,尤其涉及一种中继资源的请求方法、调度方法及设备。
背景技术
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。以较简单的两跳中继为例,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。
5G技术在研究用无线中继作为回传。无线中继回传技术也包括采纳6GHz以上的无线回传链路。网络频段越高会导致无线回传的传输距离更短。为了有效地达到更好多条传输,无线回传的之间的距离也会更加短,部署更加密集。集成接入和回传(Integrated Access and Backhaul,IAB)设备是5G技术中的中继设备,IAB通过宿主集成接入回传(Donor IAB,DIAB)设备接入核心网,DIAB可以理解为IAB接入核心网的基站。当一个新的集成接入回传(IAB)设备部署入网或一个IAB的UE资源需求不断上升,IAB需要向宿主集成接入回传(Donor IAB,DIAB)设备请求更多的资源。相关技术中没有对IAB的资源调度进行规定。
