Title:
APPARATUS AND METHOD FOR HYBRID HIERARCHICAL PARAMETER TRACKING FOR CSI ESTIMATION
Document Type and Number:
WIPO Patent Application WO/2022/014950
Kind Code:
A1
Abstract:
Methods and apparatuses for hybrid hierarchical parameter tracking for CSI estimation in a wireless communication system. The methods and apparatuses include receiving uplink signals comprising a channel state information (CSI) or a sounding reference signal (SRS); performing a channel parameter tracking operation to determine channel parameters that change less than a first threshold amount based on the received uplink signals; performing a channel parameter prediction operation to determine the channel parameters that change greater than a second threshold amount on an output of the channel parameter tracking operation; and performing a channel prediction operation for downlink channels based on an output of the channel parameter tracking operation and the channel parameter prediction operation.
