Title:
ENHANCEMENT OF BEAM MANAGEMENT FOR MULTI-TRP OPERATION
Document Type and Number:
WIPO Patent Application WO/2023/004612
Kind Code:
A1
Abstract:
Configuring channel state information reference signal (CSI-RS) reporting at a network may include encoding a channel state information (CSI) reporting configuration communication for transmission to a user equipment (UE) that is in connected mode with both a first transmission and reception point (TRP) and a second TRP. The CSI reporting configuration may include a first group of CMR (Channel Measurement Resource) resources for the first TRP, and a second group of CMR resources for the second TRP. A CSI measurement communication received from the UE, may be measurements based on the CSI-RS reporting configuration communication. Based on the CSI measurement communication, one or more downlink data transmissions may be scheduled.
