1. In a transmitting station operable to transmit communication signals in bursts to remote communication stations upon a plurality of time slots defined upon at least a first carrier, an improvement of beamforming apparatus for forming antenna beam patterns during at least two successive time slots defined upon the at least the first carrier, said beamforming apparatus comprising:

  • an allocator coupled to receive indications of locations at which the remote communication stations are positioned. Said allocator for allocating a first remote communication station to which to transmit a first communication signal upon a first time slot of the at least two successive time slots and for allocating at least a second remote communication station to transmit at least a second communication signal during at least a second time slot of the at least two successive time slots, the first and the at least second remote communication stations, respectively, indicated to be positioned within a first selected area, the first time slot and the second time slot being allocated based, at least in part, on the indication that the first and the at least second remote communication station are positioned within the first selected area, the first time slot differing from the second time slot;

    a beamformer operable responsive to allocations made by said allocator, said beamformer for forming antenna beam patterns by which to permit transmission of the first and the at least second communication signals, respectively, upon the at least two successive time slots to the first and the at least second remote communication stations; and

    wherein the antenna beam patterns formed by said beamformer during the two successive time slots at least partially overlap in time during at least a portion of the two successive time slots.
