Full-duplex wireless communication system using polarization

An apparatus in a first transceiver capable of transmitting and receiving wireless signals to and from at least a second transceiver, the apparatus 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.

A method for transmitting and receiving wireless signals by a first transceiver, the method comprising:

• applying a beamforming weight to a first signal to steer a beam on which the first signal is transmitted and a first polarization weight to the first signal in a single step by applying a combined beamforming and polarization weight to the first signal;
• transmitting, using at least one of a plurality of transmitter antennas in the first transceiver, the first signal with the first polarization weight to at least a second transceiver;
• and
• receiving, using at least one of a plurality of receiver antennas in the first transceiver, a second signal with a second polarization from the second transceiver in a same frequency band and during a same time period as the transmitting of the first signal, wherein the second polarization is cross polarized with the first polarization.
