A method of operating an array of antennas in a wireless communication system to provide user-specific azimuth and elevation beamforming is described. The method includes providing a product codebook structure consisting of both an azimuth and elevation portion. A receiver receives reference signals from a transmitter corresponding to both the azimuth and elevation portions of the array of antennas. The method also includes determining the index of the azimuth codebook portion of the product codebook from the azimuth portion of the received reference signals and determining the index of the elevation codebook portion of the product codebook from the elevation portion of the received reference signals. Apparatus and computer readable media are also described.
