Abstract: A system and method for employing six-bit rank 1 and 2 codebooks for four transmit antennas is provided. A method for communications device operation includes estimating a communications channel between the communications device and a controller serving the communications device, thereby producing a channel estimate, quantizing the channel estimate using a codebook, thereby producing a selected codeword, and transmitting an index corresponding to the selected codeword from the codebook to the controller. The codebook includes a plurality of first level codewords, with each first level codeword having a plurality of subsidiary codewords. The quantizing is a search of only the first level codewords followed by a search of a subset of the plurality of subsidiary codewords, and the codebook is based on a rank of communications between the communications device and the controller.
