1. A base station (BS) in a wireless communication, the BS comprising:
a transceiver configured to receive a sounding reference signal (SRS); and
a processor operably connected to the transceiver, the processor configured to:
partition, based on a partition policy, a frequency band of the SRS into sub-bandwidths in a frequency domain,
generate, based on previously stored channel state information (CSI) in memory and the partition policy, a set of chunks corresponding to respective sub-bandwidths,
perform channel prediction (CHPD) operations corresponding to the respective sub-bandwidths to generate channel parameters, wherein different CHPD operations are applied to the respective sub-bandwidths,
combine the channel parameters predicted from the respective sub-bandwidths in the frequency domain, and
perform, based on the combined channel parameters, a channel estimation and prediction operation.
