Abstract: Briefly, in accordance with one or more embodiments, a base transceiver station having a first set of antennas and a second set of antennas geographically separated from the first set of antennas transmits a reference signal to a first device, and receives feedback from the first device. The feedback represents information that can be used to construct a weight adjustment vector. The base transceiver station selects a precoding vector from a codebook based at least in part on the feedback received from the first device, calculates the weight adjustment vector based at least in part on the feedback, and applies the weight adjustment vector to the selected precoding vector to provide an adjusted precoding vector. The base transceiver station then may transmit data to the first device using the adjusted precoding vector.
