US 2025/0063382 A1 · 60 GHZ BEAM MANAGEMENT FOR WIRELESS LOCAL AREA NETWORKS (WLANS)

Abstract

This disclosure provides methods, devices and systems for increasing carrier frequencies for wireless communications in wireless local area networks. Some implementations more specifically relate to beamforming training operations that support wireless communications on carrier frequencies above 7 GHz. In some aspects, a beamforming initiator may initiate a beamforming training operation by transmitting a number (N) of beamforming training (BFT) packets in N TX beam directions, respectively, on a carrier frequency above 7 GHz. The beamforming responder receives one or more of the BFT packets and provides feedback to the beamforming initiator indicating the TX beam direction associated with the BFT packet having the highest received signal power. In some aspects, the beamforming responder may train its RX antennas for RX beamforming concurrently while the beamforming initiator trains its TX antennas. In some other aspects, the beamforming responder may train its RX antennas after the beamforming initiator trains its TX antennas.
