Title:
METHOD AND APPARATUS FOR REPORTING OF TIME-DOMAIN CHANNEL CORRELATION PROPERTIES
Document Type and Number:
WIPO Patent Application WO/2024/049134
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 reporting of time-domain channel correlation properties are provided. A method includes receiving a configuration about a CSI report. The configuration includes information about (i) M non-zero power (NZP) CSI reference signal (RS) resources for tracking, (ii) a number (K) of time-domain correlation values, and (iii) delay values τ
k
for k = 0,1,..., K - 1. The method further includes, based on the configuration: measuring the M NZP CSI-RS resources for tracking, determining, based on the measurement, the K time-domain correlation values, wherein a k-th correlation value is between two CSI-RS transmission occasions that are separated by one of the delay values τ
k
, and quantizing a value for an amplitude of each of the K time-domain correlation values. The method further includes transmitting the CSI report including an indicator, for each of the K time-domain correlation values, indicating the quantized value of the amplitude.
