Abstract:
A communication device includes a donor receiver that receives a plurality of first beam of input radio frequency (RF) signals. The communication device further includes a service transmitter that transmits a plurality of second beam of RF signals in a first radiation pattern to a user equipment (UE). The communication device further includes control circuitry that detects an amount and a direction of reflected RF signals at the donor receiver. The control circuitry applies polarization to the plurality of second beam of RF signals and calibrates the polarization to minimize the reflected RF signals at the donor receiver. A second radiation pattern is generated for the plurality of second beam of RF signals and communicated to the UE based on the calibrated polarization.
