Title:
METHOD AND APPARATUS FOR MULTIPLEXING CSI FOR MULTI-TRP COHERENT JOINT TRANSMISSION
Document Type and Number:
WIPO Patent Application WO/2024/080816
Kind Code:
A1
Abstract:
The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. Methods and apparatuses for multiplexing channel status information (CSI) for a multi-transmission reception point (TRP) coherent joint transmission in a wireless communication system a method performed by a UE is provided. The method includes receiving information about a CSI report associated with N trp ≥ 1 CSI reference signal (CSI-RS) resources, where the CSI report includes a CSI Part 1 and a CSI Part 2 and, based on the information, determining the CSI Part 2 including groups G1 or G2. An amplitude coefficient indicator and a phase coefficient indicator are included in G1 or G2 based on a priority value Pri(l,i,f,r) =2·, (I) The method further includes transmitting the CSI Part 1 and the determined CSI Part 2.
