1. An apparatus of a wireless communication device, comprising:
an antenna array including Nr antennas and

OG Complex Work Unit Drawing
 antenna sub-arrays, where Nrrf indicates a number of RF-chains of the apparatus; and
processing circuitry configured to:
determine an angle of arrival of a received signal received at two or more of the

OG Complex Work Unit Drawing
 antenna sub-arrays; and
adjust phase shifters of the apparatus according to the angle of arrival,
wherein the angle of arrival is determined by beamforming at the two or more antenna sub-arrays, and
wherein the processing circuitry is configured to set initial antenna sub-array beamforming vectors for the two or more antenna sub-arrays such that at least two of the two or more antenna sub-arrays have a same array pattern.
