Abstract
In a wireless communication system that traverses a physical barrier, a serving transceiver determines a downlink beamforming matrix. The serving transceiver determines a downlink power based on the downlink beamforming matrix. A network transceiver beamforms and amplifies a downlink signal based on the downlink beamforming matrix and downlink power. The network transceiver wirelessly transfers the downlink signal through the physical barrier to the serving transceiver. Contemporaneously, the network transceiver determines an uplink beamforming matrix. The network transceiver determines an uplink power based on the uplink beamforming matrix. The serving transceiver beamforms and amplifies an uplink signal based on the uplink beamforming matrix and uplink power. The serving transceiver wirelessly transfers the uplink signal through the physical barrier to the network transceiver.
