Abstract:
1. A method implemented in a first base station included in a network having multiple neighbor base stations, where the first base station is configured to serve a first user equipment (UE) and the neighbor base stations each serves a corresponding neighbor UE, the method comprising: acquiring local radio performance parameter information from the neighbor base stations; selecting antenna beamforming parameters for the first base station to use to transmit to the first UE based on the local radio performance parameter information; and transmitting a radio signal to the first UE using the selected antenna beamforming parameters, wherein the first base station selects optimal antenna beamforming parameters based on the local radio performance parameter information by determining a solution for a non-convex optimization problem where a total transmit power for the first and neighbor base stations is minimized while satisfying a first quality of service for the first UE and corresponding quality of services for the neighbor UEs.
