A communication device includes a donor receiver that receives a first beam of input radio frequency (RF) signals from a base station or a network node. The communication device further includes a service transmitter that transmits a 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 echo signals at the donor receiver. The control circuitry applies polarization to the second beam of RF signals transmitted to the UE and calibrates the polarization to minimize the echo signals at the donor receiver. A second radiation pattern is generated for the second beam of RF signals and communicated to the UE based on the calibrated polarization. The communication of the second beam of RF signals in the generated second radiation pattern further reduces the echo signals at the donor receiver.

Communication device and method for echo signals management

A communication device includes a service transmitter (Tx) configured to transmit a second beam of RF signals in a first radiation pattern to a user equipment (UE). The communication device further includes a control circuitry configured to: detect an amount and direction of echo signals at the donor receiver Rx corresponding to reflected RF signals in an environment surrounding a communication device; determine an installation location for the communication device based on echo signal measurements at one or more different locations; adjust polarization of the second beam of RF signals to minimize the echo signals at the donor receiver Rx based on the echo signal; and generate a second radiation pattern for at least the second beam of RF signals based on the amount and direction of the echo signals in the environment detected at the donor receiver Rx.

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.
