Technical Field

In large-scale MIMO, multiple antennas form a narrow beam pointing to a specific direction by beamforming to improve communication quality. The beams formed by multi-antenna beamforming are generally narrow, and the base station needs to obtain a correct beam pointing direction to perform effective communication with the user equipment. In order to obtain a correct beam pointing direction, the base station needs to form a plurality of transmission beams pointing in different directions and transmit wireless signals on the transmission beams. The user equipment needs to measure the reception quality of the radio signal on the different transmission beams and feed back the identity of the transmission beam corresponding to the best reception quality to the base station. How to perform efficient transmit beam identification feedback with minimal overhead is a problem to be solved.
