SYSTEMS AND METHODS FOR BEAMFORMING FEEDBACK IN mmWAVE WIRELESS LOCAL AREA NETWORKS.

摘要

A responder performing a hybrid beam forming operation by having multiple antennas configured to receive a training packet, responsively generate a beam-formed receive signal by processing the received training packet with previously determined analog beam coefficients, determine whether digital baseband channel (DBC) tracking is indicated based on a tracking-type parameter contained within the received training packet, process a non-precoded training signal within the beam-formed receive signal and responsively determine a DBC estimate, and provide a feedback message having transmitter precoder data based on the DBC estimate.
