摘要:
Techniques for receiving reference signals from multiple nodes and determining channel state information (CSI) for the nodes are disclosed. A user equipment (UE) may determine and report CSI for the multiple nodes to support data transmission to the UE. The nodes may transmit reference signals based on different configurations. The configuration for each node may indicate when, where, and how the node transmits its reference signal. The UE may determine CSI for different nodes and/or different combinations of nodes based on the reference signals transmitted by these nodes as well as an indication of which subframes to use to determine each CSI reported by the UE. The UE may report different CSIs for different subframes and may receive data transmission sent by a single node or a combination of nodes based on the reported CSIs.
摘要(中):
公开了用于从多个节点接收参考信号并确定节点的信道状态信息(CSI)的技术。 用户设备(UE)可以确定并报告多个节点的CSI以支持向UE的数据传输。 节点可以基于不同的配置发送参考信号。 每个节点的配置可以指示节点发送其参考信号的时间,地点和方式。 UE可以基于由这些节点发送的参考信号来确定不同节点和/或节点的不同组合的CSI以及用于确定由UE报告的每个CSI的哪些子帧的指示。 UE可以针对不同的子帧报告不同的CSI,并且可以基于所报告的CSI接收单个节点或节点的组合发送的数据传输。
