METHOD AND APPARATUS FOR TRANSMIT AND RECEIVE BEAM DETERMINATION

Aspects of the present disclosure enable determination of a transmit beamformer used for data transmission. The determination of the transmit beam is based on beamformed reference signals (e.g., CSI-RS, SSB) transmitted by the transmitter, such as a base station, and received by the receiver, such a...

Zusammenfassung:Aspects of the present disclosure enable determination of a transmit beamformer used for data transmission. The determination of the transmit beam is based on beamformed reference signals (e.g., CSI-RS, SSB) transmitted by the transmitter, such as a base station, and received by the receiver, such as a UE. The receiver feeds back information based on an angle of arrival (AoA) of the beamformed reference signal to help the transmitter determine a transmit beamformer used by the transmitter to transmitter data to the receiver. In some embodiments, the feedback information may include a projection of an angle of arrival at the receiver of a propagation path have a strongest measures reference signal on a receive beamformer. In some embodiments, the feedback information may include a beamformer to be used at the transmitter, that has been determined at the receiver.
