Abstract

A wireless communications system includes a first transceiver with a first phased array antenna panel having horizontal-polarization receive antennas and vertical-polarization transmit antennas, where the horizontal-polarization receive antennas form a first receive beam based on receive phase and receive amplitude information provided by a first master chip, the vertical-polarization transmit antennas form a first transmit beam based on transmit phase and transmit amplitude information provided by the first master chip. The wireless communications system may include a second transceiver having vertical-polarization receive antennas and horizontal-polarization transmit antennas in a second phased array antenna panel, where the vertical-polarization receive antennas form a second receive beam based on receive phase and receive amplitude information provided by a second master chip, the horizontal-polarization transmit antennas form a second transmit beam based on transmit phase and transmit amplitude information provided by the second master chip.
