1. A method of allocating sets of subcarriers, each of the sets of subcarriers including a plurality of subcarriers, by a base station which communicates with a plurality of subscribers using an orthogonal frequency-division multiple access (OFDMA) system, the method comprising:

  • allocating to a first subscriber a first set of subcarriers to be used for a first data transmission to the first subscriber, the allocated first set of subcarriers including a plurality of subcarriers at least one subcarrier of the plurality of subcarriers being disjoint in frequency from another subcarrier of the plurality of subcarriers to obtain frequency diversity; and

    allocating to a second subscriber a second set of subcarriers to be used for a second data transmission to the second subscriber, the second data transmission to occur simultaneously with the first data transmission to the first subscriber using the allocated first set of subcarriers, the allocated second subcarriers including only consecutive subcarriers.
