1. A wireless communication system comprising:
- a first transceiver configured to transmit and receive wireless signals to and from at least a second transceiver, the first transceiver comprising;
transmitter processing circuitry configured to apply a beamforming weight to a first signal to steer a beam on which the first signal is transmitted and to apply a first polarization weight to the first signal in a single step by applying a combined beamforming and polarization weight to the first signal;
a plurality of transmitter antennas, at least one of the transmitter antennas configured to transmit the first signal with the first polarization weight to at least the second transceiver; and
a plurality of receiver antennas, at least one of the receiver antennas configured to receive a second signal with a second polarization from the second transceiver, wherein the second polarization is cross polarized with the first polarization.

Abstract
A system, apparatus, and method use full duplexing with polarization. A wireless communication system includes a first transceiver configured to transmit and receive wireless signals to and from at least a second transceiver. The first transceiver includes a plurality of transmitter antennas and a plurality of receiver antennas. At least one of the transmitter antennas is configured to transmit a first signal with a first polarization weight to at least the second transceiver. At least one of the receiver antennas is configured to receive a second signal with a second polarization from the second transceiver. The second polarization is cross polarized with the first polarization.
