Abstract
A method of wireless communication at a serving base station identifies a potential interference condition based on an uplink/downlink configuration mismatch. The method includes signaling, to a neighbor base station, to restrict transmissions based on the identified potential interference condition. The transmissions may be restricted by beamforming the transmissions into a different direction and/or blocking transmissions on a frequency. The signaling prompts the neighbor base station to restrict downlink transmissions that will potentially interfere with uplink control channel transmissions received at the serving base station, or to restrict uplink transmissions, intended for the neighbor base station, that will potentially interfere with downlink control channel transmissions from the serving base station.
