Abstract:

Aspects of the disclosure relate to a multi-antenna wireless user equipment (UE) calculating a covariance matrix corresponding to a covariance of signals received from each of its antennas. The UE further calculates the eigenvectors of the covariance matrix, and transmits feedback including information corresponding to the eigenvectors. Based on this information, a base station can determine to alter a number of beams for transmitting information to the UE, efficiently improving the reliability of transmission to the UE. Other aspects, embodiments, and features are also claimed and described.
