Abstract
A system and method for wireless communications with codebook adaptation with low feedback overhead are provided. A method for controller operations includes receiving a first channel information from a communications device, estimating channel statistics based on the first channel information, adapting a codebook using the channel statistics, and receiving a second channel information from the communications device. The method also includes constructing a precoding matrix from the second channel information and the adapted codebook, and transmitting information precoded by the precoding matrix to the communications device.
