Abstract
Systems, methods, and other embodiments associated with a hybrid beamforming architecture are described. According to one embodiment, an apparatus includes a beamforming mode detection logic configured to select a beamforming mode based, at least in part, on a packet received from a wireless device. The apparatus also includes a beamformee unit and a beamformer unit. The beamformee unit is configured to derive steering information from channel related information in the packet. The beamformer unit is configured to provide weights from a steering matrix to a transmitter performing transmit beamforming on a subsequent packet being transmitted to the wireless device. The beamforming mode detection logic routes at least part of the packet to one or both of the beamformee unit and the beamformer unit based, at least in part, on the selected beamforming mode.
