Title:
METHOD AND APPARATUS FOR CSI REPORTING IN A WIRELESS COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2022/169212
Kind Code:
A1
Abstract:
The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. A method performed by a user equipment (UE) in a wireless communication system comprises receiving configuration information about a channel state information (CSI) report, the configuration information including codebook parameters (M,α,β), wherein: M is a number of frequency domain basis vectors, α is a number ≤ 1, and β is a number ≤ 1; identifying values of M,α,and β; dertermining a value of K1 based on α, where K1 is a number of selected CSI reference signal (CSI-RS) ports from a total of P CSI-RS ports; determining a maximum number of non-zero coefficients based on β; determining the CSI report based on the values of M, K1, and the maximum number of non-zero coefficients; and transmitting the CSI report.
