摘要： This disclosure describes methods, apparatus, and systems related to applying channel smoothing to beamformed vectors in wireless communications between a transmitter device and a receiver device. In a first aspect, a device is disclosed that identifies disruptions between at least two first beamforming vectors on adjacent frequencies in a communication channel between the device and a first device of a plurality of user devices. The device determines one or more second beamforming vectors proximate to the identified disruption. The device utilizes the one or more second beamforming vectors to smooth the communication channel between the device and the first device of the plurality of user devices.
