Abstract:
1. In a wireless network employing Spatial Division Multiplexing Access (“SDMA”) in at least one of the cells associated with said wireless network, a method for dynamically allocating transmission resources to different subscriber devices, which method comprising the steps of: providing at least one base station comprising at least one antenna array; providing one or more sectors associated with said wireless communications network; dividing one or more of said one or more sectors into a plurality of virtual sub-sectors each generated to allow communications between the base station and at least one respective subscriber; from among said plurality of the virtual sub-sectors selecting at least one pair of subscriber devices, wherein each of the pair of subscriber devices is not interfered substantially by transmissions directed to the other subscriber of that pair; for each of said one or more divided sectors, generating plurality of time frequency allocation maps; transmitting said generated maps to all virtual sub-sectors associated with a respective sector of said one or more divided sectors; and for each of said one or more sectors, beamforming the transmissions to be conveyed to the subscriber devices' pairs, summing them and conveying the summed result towards said array antenna.
