1. A user equipment (UE), comprising:
a data storage device configured to store a first beamforming codebook that corresponds to a plurality of antennas of the UE; and
processing circuitry configured to:
generate one or more measurements of a receive beam space of the first beamforming codebook according to reduced or compressed dimensions for the receive beam space of the first beamforming codebook, wherein a number of the one or more measurements is less than a number of receive beams of the first beamforming codebook, the one or more measurements corresponding to the entire beam space;
determine a best receive beam of the first beamforming codebook based on the one or more measurements; and
use the best receive beam of the first beamforming codebook to receive data bearing signals from a cellular base station.
