1. A method, comprising:

  • in a wireless transceiver;

    determining a transmit path phase difference between a first antenna and a second antenna in the wireless transceiver;

    determining a receive path phase difference between the first and second antennas;

    determining a wireless channel phase difference associated with the first and second antennas based on downlink radio frequency signals received by the first and second antennas from a base station antenna of a base station; and

    transmitting uplink radio frequency signals via the first and second antennas to the base station based on a composite phase difference equal to a sum of the trans it path phase difference, the receive path phase difference and the wireless channel phase difference.
