Ofdma with adaptive subcarrier-cluster configuration and selective loading

摘要

A method of allocating clusters, each of the clusters comprising a plurality of subcarriers, by a base station which communicates with a plurality of subscriber stations using multiple access technology in a cell, the method comprising:
allocating to a first subscriber station a diversity cluster to be used for a first data transmission to the first subscriber station by providing a first cluster identification, the allocated diversity cluster including a plurality of disjoint subcarriers; and
allocating to a second subscriber station a coherence cluster to be used for a second data transmission to the second subscriber station by providing a second cluster identification, the second data transmission to occur during the same time period as the first data transmission to the first subscriber station using the allocated diversity cluster, the allocated coherence cluster including only consecutive subcarriers.
