1. A method of wireless communication operable at a user equipment (UE) configured for operation in a cell configured for downlink beamforming over a plurality of directional beams, the method comprising:
receiving a first reference signal on a downlink resource;
selecting a beam corresponding to one or more directional beams of the plurality of directional beams, based on a set of one or more channel characteristics that are based on the first reference signal; and
transmitting a report identifying the selected beam, including indicating a direction of the selected beam and indicating an angular width of the selected beam, wherein the direction of the selected beam is indicated based on a codeword from a codebook that maps a plurality of codewords to the plurality of directional beams and wherein the codeword corresponds to a vertical beam component of the selected beam and a horizontal beam component of the selected beam.
