CHANNEL COVARIANCE MATRIX DETERMINATION BASED ON CHANNEL MEASUREMENTS FOR COMMUNICATION SYSTEMS

摘要

An apparatus is configured to be employed within a base station. The apparatus comprises baseband circuitry, which includes a radio frequency (RF) interface and one or more processors. The one or more processors are configured to generate channel state information reference signals (CSI-RS) for an antenna array and provide the CSI-RS to the RF interface for transmission to a user equipment (UE) device, receive one or more report matrices based on sets of measurements of the CSI-RS and from the RF interface, and generate a channel covariance matrix based on the received one or more report matrices.
