Abstract
Systems, methods, and other embodiments associated with a hybrid beamforming architecture are described. According to one embodiment, a first wireless device includes a transmitter and a baseband beamforming processing unit. The baseband beamforming processing unit includes a steering matrix calculation unit and a steering matrix cache. The steering matrix calculation unit is configured to derive a steering matrix from channel related information in a first packet received from a second wireless device. The steering matrix includes weights. The steering matrix cache is configured to (i) store the steering matrix derived from the channel related information, and (ii) provide the weights from the steering matrix to the transmitter. The transmitter is configured to, based on the weights from the steering matrix, perform transmit beamforming on a second packet being transmitted to the second wireless device from the first wireless device.
