PROBLEM TO BE SOLVED: To provide a resource allocation method for dynamically allocating transmission resources to different subscriber devices, in a wireless communication network employing Spatial Division Multiplexing Access (SDMA) system. SOLUTION: The method includes the steps of: providing a base station comprising an antenna array; dynamically dividing one or more of the sectors into a plurality of virtual sub-sectors, each allowing communications between the base station and at least one respective subscriber; from among the 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 transmission signals directed to the other subscriber of that pair; for each of the divided sectors, generating a plurality of time frequency allocation maps; transmitting the generated maps to all virtual sub-sectors associated with the respective divided sectors; and for each of the sectors, beamforming the transmission signal to be conveyed to the subscriber devices' pairs, and conveying a summed result towards the array antenna.
