Title:
METHOD AND APPARATUS FOR CSI REPORTING BASED ON A WINDOW OF BASIS VECTORS
Document Type and Number:
WIPO Patent Application WO/2024/049206
Kind Code:
A1
Abstract:
The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. A method includes receiving a configuration about a CSI report including information about NTRP non-zero power (NZP) CSI-reference signal (RS) resources, where NTRP ≥ 1, and a parameter codebookType set to type-II-CJT-r18 or type-II-PortSelection-CJT-r18. The method further includes determining, for each layer l = 1,..., v, an indicator for indicating an index of a strongest coefficient among K
l
NZ coefficients, where K
l
NZ is a total number of non-zero coefficients that are associated with Z NZP CSI-RS resources, and Z ≤ NTRP, and a number of bits P
l
for the indicator. The method further includes transmitting the CSI report including, for each layer, P
l
bits for the indicator. When codebookType = type-II-CJT-r18, a value of P
l
depends on a value of K
l
NZ or a value of [Formula I]. When codebookType = type-II-PortSelection-CJT-r18, the value of P
l
depends on a value of [Formula II].
