Predictive beamforming and subarray selection
A wireless device of the present disclosure may be able to reduce the time needed to determine a subarray and/or beamforming direction used for mmW communication. An apparatus may maintain first information associated with a correlation between each of a plurality of wireless device orientations and a plurality of nodes, at least one subarray, and a corresponding beamforming direction. The apparatus may communicate with a first node using a first beamforming direction selected from the first information. In certain aspects, the first beamforming direction may be correlated with a first orientation of a first subarray at the wireless device and the first node. The apparatus may perform a handoff procedure from the first node to a second node when a position of the first subarray changes from the first orientation to a second orientation.
