1. A method comprising:
receiving channel state information reference signals (CSI-RS) configuration information from a base station (gNB) by a user equipment (UE), wherein the CSI-RS configuration comprises CSI-RS resources and a CSI computation period having one or multiple non-overlapping sub-periods within the CSI computation period in time domain;
measuring multiple occasions of CSI-RS of a downlink channel that is received over the configured CSI-RS resources;
estimating CSI of the downlink channel for the CSI computation period, wherein the UE estimates the CSI considering timing correlation of the multiple occasions of CSI-RS; and
reporting the estimated CSI of the downlink channel to the gNB, wherein the estimated CSI is reported based on the CSI computation period.
