Over-the-air interference coordination among base stations

A method for wireless communications at a device in a wireless network, comprising:

• determining a communication parameter of a user equipment (UE) served by a serving base station or of the serving base station or of both;
• dynamically selecting a beamforming interference coordination scheme from a plurality of beamforming interference coordination schemes for the serving base station and one or more neighboring base stations based at least in part on the communication parameter, the plurality of beamforming interference coordination schemes defining different configurations for communication beam usage at the one or more neighboring base stations;
• and
• transmitting an indication of the dynamically selected beamforming interference coordination scheme to a base station.

A method for wireless communications at a first base station, comprising:

• receiving an interference coordination message from a second base station;
• determining a dynamically selected beamforming interference coordination scheme from a plurality of beamforming interference coordination schemes based at least in part on the interference coordination message, the plurality of beamforming interference coordination schemes defining different configurations for communication beam usage at the first base station;
• modifying a scheduling decision based at least in part on the dynamically selected beamforming interference coordination scheme;
• and
• communicating with one or more user equipments (UEs) according to the modified scheduling decision.

A method for wireless communications at a user equipment (UE), comprising:

• receiving a message from a serving base station comprising an indication of a dynamically selected beamforming interference coordination scheme from a plurality of beamforming interference coordination schemes and an indication of a scheduling decision, the plurality of beamforming interference coordination schemes defining different configurations for communication beam usage at a neighboring base station;
• transmitting an interference coordination message indicating the dynamically selected beamforming interference coordination scheme and the scheduling decision to at least the neighboring base station;
• and
• communicating with the serving base station based at least in part on the scheduling decision.
