Abstract: Systems and methods for managing interference in a communication network include transmitting a first downlink signal from a first transmit/receive point (TRP) to an electronic device using a beam. The electronic device can also receive a second downlink signal from a second TRP, where a portion of the first downlink signal from the first TRP interferes with the second downlink signal. The first TRP then receives a series of uplink pilot signals from the electronic device. Using the received uplink pilot signals, the first TRP can then estimate the angle of departure (AoD) for the intended signal (first downlink signal), and the AoD for the interference signal. The first TRP can then reconfigure the beam used to transmit the first downlink signal based on the estimated AoDs for the intended signal and interference signal to manage the interference effect that the first leakage signal has on the second downlink signal.
