Abstract

本申请针对CSI‑RS resource相关的配置和指示问题，设计相应的配置和指示技术，包括：网络设备将CSI‑RS resource配置为用于信道测量的资源集合和用于干扰测量的资源集合，并且提供了多种信道测量的资源集合与干扰测量的资源集合对应方式；在另一实现方式中，网络设备针对一个CSI‑RS resource set，配置其中的资源既包含做信道测量的资源也包含做干扰测量的资源；网络设备向终端发送测量参考信号的指示信息以指示所述用于信道测量的资源集合或者一个集合中哪些资源是做信道测量的资源，哪些资源是做干扰测量的资源。如此，网络设备对CSI‑RS resource进行了灵活多样的配置，并且尽可能的减小指示开销，可以满足NR***下，多用户终端进行信道和干扰测量的需求。
