Title:
TRANSMISSION RECEPTION POINT SELECTION FOR COHERENT JOINT TRANSMISSIONS
Document Type and Number:
WIPO Patent Application WO/2023/206348
Kind Code:
A1
Abstract:
Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive channel state information (CSI) reference signals (CSI-RSs) from multiple transmission reception points (TRPs) and may perform measurements on the CSI-RSs. The UE may then select a subset of the multiple TRPs with which to communicate, and the UE may transmit an indication of the selected TRPs in a CSI report. In some cases, the UE may indicate a common subset of TRPs with which the UE may communicate on multiple layers, or the UE may indicate a respective subset of TRPs with which the UE may communicate on each layer of multiple layers. The UE may also provide additional information in the CSI report for the selected TRPs. The selected TRPs may then use the additional information provided in the CSI report to identify suitable configurations for communicating with the UE.
