Patent ID: 11832242

Abstract:
Methods, systems, and devices for wireless communications are described. A user equipment (UE) may be configured to measure sidelink channel conditions for a group of UEs and transmit a report (e.g., a channel state information (CSI) report) to a base station indicating the sidelink channel conditions. The base station may transmit control information (e.g., group-common downlink control information (GC-DCI)) to the group of UEs triggering the UEs to transmit sidelink reference signals (e.g., CSI reference signals (CSI-RS)) on the sidelink channels so that the UE can measure the sidelink channel conditions and transmit the report. Based on the report, the base station may transmit control information (e.g., a downlink control information (DCI) message) scheduling sidelink communications for the group of UEs. In some examples, the UE may act as a relay node for the group of UEs, and forward control information to the group of UEs.
