1. A user equipment (UE) comprising:
a transceiver configured to receive a configuration about a channel state information (CSI) report, the configuration including information about (i) M non-zero power (NZP) CSI reference signal (RS) resources for tracking, where M≥1, (ii) a number (K) of time-domain correlation values, where K≥1, and (iii) delay values τk for k=0, 1, . . . , K−1; and
a processor operably coupled to the transceiver, the processor, based on the configuration, configured to:
measure the M NZP CSI-RS resources for tracking,
determine, 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 τk, and
quantize a value for an amplitude of each of the K time-domain correlation values,
wherein the transceiver is further configured to transmit the CSI report including an indicator, for each of the K time-domain correlation values, indicating the quantized value of the amplitude.
