Title:
METHOD AND APPARATUS TO ENABLE SEGMENTED CSI REPORTING IN WIRELESS COMMUNICATION SYSTEMS
Document Type and Number:
WIPO Patent Application WO/2020/149706
Kind Code:
A1
Abstract:
A method for operating a user equipment (UE) for channel state information (CSI) feedback in a wireless communication system is provided. The method comprises receiving, from a base station (BS), CSI reference signals (CSI-RSs) and CSI feedback configuration information, estimating a channel based on the received CSI-RSs, determining, based on the estimated channel and the CSI feedback configuration information, at least one of a number of non-zero coefficients for each layer of a total number of total layers, and a sum of the non-zero coefficients across each of the totallayers as a total number of non-zero coefficients. The method further comprises transmitting, to the BS, the CSI feedback including the sum of the non-zero coefficients value over an uplink (UL) channel.
