Abstract

According to various aspects, techniques to enable implicit and/or explicit transmit (Tx) beamforming in a wireless personal area network are provided. In particular, the implicit transmit beamforming may be enabled during certain events, frames, and/or other conditions when a channel between a beamformer and a beamformee is reciprocal (i.e., packets are received and transmitted on the same frequency). In such cases, the beamformer may estimate channel state information (CSI) based on a packet received from the beamformee and use the estimated CSI to steer a beam in a direction towards the beamformee. In use cases that implement explicit transmit beamforming, the beamformee may estimate the CSI based on a packet received from the beamformer and provide the estimated CSI to the beamformer, which may then use the estimated CSI received from the beamformee to steer a beam in a direction towards the beamformee.
