Title:
CODEBOOK REPORT DESIGN TO SUPPORT DYNAMIC MULTI-TRP COHERENT JOINT TRANSMISSION OPERATION
Document Type and Number:
WIPO Patent Application WO/2024/036205
Kind Code:
A3
Abstract:
Apparatus and methods are provided for a user equipment (UE) to perform dynamic point selection (DPS) in a wireless network. The UE receives signals from a plurality of transmission and reception points (TRPs). Different non-zero power (NZP) channel state information (CSI) reference signal (RS) resources are configured for different ones of the plurality of TRPs. The UE selects, based on the signals, one or more selected TRP of the plurality of TRPs for multiple TRP (multi-TRP) coherent joint transmission (CJT) CSI feedback. The UE configures a CSI-RS resource indicator (CRI) field in the multi-TRP CJT CSI feedback to indicate the one or more selected TRP and reports the multi-TRP CJT CSI feedback to the wireless network.
