Methods and apparatus for simplified beamforming

摘要

Systems, methods, and devices for simplified beamforming are provided. In one aspect, a plurality of signals from a signal transmitter are received over a wireless network on one or more receive antennas. One or more phase differences are then determined that maximize a signal to noise ratio of the plurality of received signals. Data representing the one or more phase differences is then transmitted to the signal transmitter.

主权项

1. A method of providing simplified beamforming data to a signal transmitter, comprising:
receiving, by a first wireless device, a plurality of signals that have been transmitted from at least two antennas of the signal transmitter over a wireless communication network; determining, by the first wireless device, one or more phase differences that maximize a signal to noise ratio of the plurality of received signals; generating, by the first wireless device, a beamforming report comprising sounding feedback relating to differences between the received plurality of signals, and an indicator of a format of the sounding feedback, the sounding feedback also representing at least the one or more phase differences; transmitting, by the first wireless device, the beamforming report to the signal transmitter.
