Title:
APPARATUS AND METHODS FOR BEAMFORMING TRACKING
Document Type and Number:
WIPO Patent Application WO/2017/215078
Kind Code:
A1
Abstract:
Signals are received from antenna elements in an antenna array, and respective phase shifts are applied to the received signals. The respective phase shifts are relative to a channel phase shift associated with each antenna element, and correspond to side angles from a current antenna beam direction of the antenna array. Control signals based on the phase shifted signals are generated to control the channel phase shifts, to provide beamforming tracking.
