Abstract:
1. An orthogonal frequency division multiplexing access (OFDMA) system comprising: a) a base station controller adapted to schedule data for a subscriber station during a soft handoff; b) a plurality of base stations operatively associated with said base station controller, each base station participating in said soft handoff being adapted to receive at least a portion of the scheduled data from said base station controller, and to transmit a first plurality of subcarriers to said subscriber station; said first plurality of subcarriers being defined in a soft handoff zone comprising a first dimension of subchannels, said first dimension of subchannels comprising said first plurality of subcarriers divided in a frequency domain; and a second dimension of divided and multiplexed orthogonal frequency division multiplexing (OFDM) symbols comprising said first plurality of subcarriers; said first plurality of subcarriers in said soft handoff zone having a subchannel definition.
