Abstract  Abstract

Briefly according to one or more embodiments the base transceiver station of the second set of antennas having a first group of antennas and on the first group of antenna geographic separation of the reference signal transmitted to the first device and receiving feedback from the first device. the feedback representation can be configured for adjusting the weight vector information. base transceiver station based at least in part on feedback received from the first device and choosing pre-coding vector from codebook based at least in part on the feedback to calculate weights adjustment vector and adjusting the weight vector to the selected precoding vector to provide adjusted precoding vector. base transceiver station may then be used to adjust the pre-coding vector to transmit the data to the first device.

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.
