Abstract:
Methods and apparatuses manage beam selection. A method for a mobile station (MS) includes identifying beamforming constraints of the MS. The method also includes performing measurement on a channel between a base station (BS) and the MS on at least one transmit (TX) beam and at least one receive (RX) beam. Additionally, the method includes sending beamforming feedback information based on the identified constraints of the MS and the channel measurement. A method for a base station (BS) includes receiving beamforming feedback information comprising at least one of radio frequency beamforming constraints of a mobile station or channel measurement information on a channel between the BS and the MS. Additionally, the method includes sending, to the MS, control information comprising an indication of at least one of MS RX beams or BS TX beams to be used in downlink communication with the MS based on the received beamforming feedback information.
