    Abstract: A system and method for wireless communications is provided. A method for operating in a communications network includes receiving a codebook, the codebook includes a plurality of codewords, and determining if the codebook satisfies a constant modulus property. The method also includes in response to determining that the codebook does not satisfy the constant modulus property, converting the codebook into a codebook satisfying the constant modulus property, and storing the codebook satisfying the constant modulus property. The method further includes storing the codebook in response to determining that the codebook does satisfy the constant modulus property, and causing to transmit a transmission to a communications device, wherein the transmission is encoded using a codeword in the stored codebook.

    Abstract: A system and method for channel information feedback in a wireless communications system is provided. A method for communications device operation includes receiving a pilot transmitted by a controller, computing a channel estimate for a channel between the controller and a communications device, the computing based on the pilot, computing a channel correlation matrix for the channel based on the channel estimate, and transmitting a reduced rank representation of the channel correlation matrix to the controller as a first feedback information. The method also includes adapting a first codebook based on the reduced rank representation of the channel correlation matrix, computing a representation of the channel using the adapted codebook, transmitting the representation of the channel as a second feedback information, and receiving a transmission beamformed based on the first feedback information and the second feedback information.
