Abstract: A wireless base station, via a first wireless beam in a beamforming codebook, transmits communications to multiple communication devices. In one implementation, the wireless base station receives respective channel matrix information from each of the multiple communication devices. The channel matrix information indicates weight coefficients applied to respective receiver antenna hardware to receive the communications. Alternatively, when reciprocity holds, the wireless base station can be configured to generate the channel matrix information based on observation of receiving communications from the one or more communication devices. Via the channel matrix information, a communication management resource associated with the wireless base station adjusts beamforming settings of the first wireless beam to best support communications with the communication devices over the first wireless beam. The communication management resource dynamically updates the beamforming codebook such that a corresponding wireless beam is angularly adjusted towards a centroid of the communication devices.

Abstract: According to one configuration, a system includes a first wireless station in communication with a second wireless station. A phase noise predictor model such as associated with the first wireless station receives phase noise information. The phase noise information captures an estimate of: i) first phase noise associated with a first wireless station, and ii) second phase noise associated with a second wireless station. Based on the received phase noise information, the predictor produces phase noise adjustment information. The predictor applies the phase noise adjustment information to adjust (compensate) a signal of the first wireless station. Adjustment of the signal results in phase noise adjustment with respect to both the first phase noise associated with the first wireless station and the second phase noise associated with the second wireless station.
