Abstract:
1. A system comprising: a plurality of transmit and receive antennas covering one sector of a cellular communication base station; a multi-beam RF beamforming matrix connected to said transmit and receive antennas; a plurality of radio circuitries connected to said multi-beam RF beamforming matrix; and a baseband module connected to said radio circuitries, wherein the multi-beam RF beamforming matrix is configured to generate one sector beam and two or more directional co-frequency beams, wherein the sector beam operates over a different frequency than said directional co-frequency beams, wherein the baseband module assigns each user equipment (UE) to the sector beam or to at least one of said directional co-frequency beams based on a cross-talk parameter at the respective UE, wherein a number M denotes the number said directional beams and a number N denotes the number of said radio circuitries and wherein M>N.
