Abstract
A system and method may include a plurality of transmit and receive antennas covering one sector of a cellular communication base station; a multi-beam RF beamforming matrix connected to the transmit and receive antennas; a plurality of radio circuitries connected to the multi-beam RF beamforming matrix; and a baseband module connected to the radio circuitries. The multi-beam RF beamforming matrix may be configured to generate one sector beam and two or more directional co-frequency beams pointed at user equipment (UEs) within the sector, as instructed by the baseband module. A number M denotes the number the directional beams and a number N denotes the number of the radio circuitries and wherein M>N.
