Abstract
Data may be transmitted from a first communications device using multiple antennas to a second communications device based on precoder feedback defining a grid of transmission beams. A first precoder index may be received from the second communications device, and a second precoder index may be received from the second communications device. At least one symbol stream may be processed based at least in part on the first and second precoder indices to generate antenna signals for respective antenna elements of the multiple antennas, and the antenna signals may be transmitted over the multiple antennas to the communications device. Related base stations and user equipment are also discussed.
