1. A communication device, comprising:
a donor receiver (Rx) configured to receive a first beam of input radio frequency (RF) signals from a base station or a network node;
a service transmitter (Tx) configured to transmit a second beam of RF signals in a first radiation pattern to a user equipment (UE);
a control circuitry configured to:
detect an amount and a direction of echo signals at the donor Rx corresponding to reflected RF signals in an environment surrounding the 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 Rx; and
generate a second radiation pattern for at least the second beam of RF signals based on the amount and the direction of the echo signals in the environment detected at the donor Rx.
