摘要:
An enhanced beamforming with interference nulling method is an improvement over prior art beamforming with interference nulling techniques. The enhanced method includes two scheduling schemes that allow all base stations to schedule their cell edge users independently and determine the information exchange among base stations over the backbone that is needed to support the scheduling activity. The method uses grouping information to perform distributed scheduling among base stations to schedule downlink transmission to cell edge users, while reducing interference to cell edge users served by neighboring base stations. The enhanced method demonstrates the base station-to-base station coordination and information exchange that is needed to enable independent base station scheduling of their cell edge users.
