1. A method performed by at least one processor for communication using multiple receive antennas over a wireless communication channel, the method comprising:
receiving, at a receiver device associated with the multiple receive antennas, a plurality of radio frequency (RF) signals based on transmission by a source device over the wireless communication channel;
estimating channel state information (CSI) corresponding to the wireless communication channel based on processing the plurality of RF signals
using at least one machine-learning network that is trained to estimate CSI and is associated with the receiver device, wherein the CSI indicates at least one of
a state of the wireless communication channel,
spatial information corresponding to the multiple receive antennas, or
scheduling information corresponding to multiple users of the wireless communication channel; and
providing, by the receiver device, the estimated CSI to the source device for processing further RF signals for transmission over the wireless communication channel.
