Beamforming in non-reciprocal uplink and downlink channels
Wireless communications systems and methods related to determining an improved beam weight for UL and/or DL transmissions are provided. A wireless communication device transmits uplink-downlink beam reciprocity information and receives via an antenna array of the wireless communication device, a plurality of downlink beam reference signals based on a beam selection. The wireless communication device receives a downlink communication signal using a reception beam configured based on an adjusted plurality of weights. Additionally, the wireless communication device adjusts a plurality of weights for the antenna array based on the received plurality of downlink beam reference signals and the UL-DL beam reciprocity information.
