摘要： Embodiments of the claimed subject matter provide a method and apparatus for virtual sectorization using an active antenna array. Embodiments of the apparatus include a transmitter for providing signals to an active antenna array. The signals cause the active antenna array to transmit a first reference signal to a first sector indicated to user equipment within the first sector by a sector identifier. The signals also cause the active antenna array to transmit a plurality of second reference signals into a corresponding plurality of second virtual sectors that overlap the first sector. The apparatus also includes a scheduler for scheduling transmission to user equipment based on feedback generated by the user equipment using the first reference signal or the second reference signals.
