1. An apparatus for a wireless communication device, the apparatus comprising:
a communication control interface; and
beamforming circuitry coupled to the communication control interface and configured to:
receive, over the communication control interface, an index value into a coarse codebook and an offset vector, the index value indicating a value within the coarse codebook, and the offset vector indicating an offset value for a desired beam relative to the index value; and
determine a new beam direction based on at least one of a horizontal offset and a vertical offset from the index value and the offset vector.
