Abstract: An apparatus comprising: a MIMO antenna for transmitting beamformed signals on a plurality of beams using a common frequency- and time-limited physical channel resource; means for computing a beamforming gain of each beam in each sub-sector in a coverage area of said plurality of beams; means for determining a beam dominance region of each beam within the coverage area of said plurality of beams; means for determining, within the dominance region of each beam, an average of the beamforming gain of each of the other beams at least partially co-locating within said beam dominance region; means for determining inter-beam interference estimations as an average interference of each beam from each of said other beams; and means for scheduling transmissions of the beams by said MIMO antenna on said common frequency- and time-limited physical channel resource based on said inter-beam interference estimations.

Abstract: An apparatus including: a MIMO antenna for transmitting beamformed signals on a plurality of beams using a common frequency- and time-limited physical channel resource; circuitry for computing a beamforming gain of each beam in each sub-sector in a coverage area of said plurality of beams; circuitry for determining a beam dominance region of each beam within the coverage area of said plurality of beams; circuitry for determining, within the dominance region of each beam, an average of the beamforming gain of each of the other beams at least partially co-locating within said beam dominance region; circuitry for determining inter-beam interference estimations as an average interference of each beam from each of said other beams; and circuitry for scheduling transmissions of the beams by said MIMO antenna on said common frequency- and time-limited physical channel resource based on said inter-beam interference estimations.
