1. A method performed by a Base Station for allocating subcarriers in an OFDMA system, the method comprising:
- determining a subscriber location within a cell; and
selecting either a coherence cluster or a diversity cluster for the subscriber based on the subscriber'"'"'s location within the cell.

Abstract
A method and apparatus for allocating subcarriers in an orthogonal frequency division multiple access (OFDMA) system is described. In one embodiment, the method comprises allocating at least one diversity cluster of subcarriers to a first subscriber and allocating at least one coherence cluster to a second subscriber.

16. A method performed by a mobile device for determining an SINR value for a cluster of subcarriers in an OFDMA system, the method comprising:
- measuring an SINR value for each subcarrier in the cluster;
determining the SINR value for the cluster based on one or more of the SINR values for the subcarrier; andreporting the SINR value for the cluster to a base station. - View Dependent Claims (17, 18, 19)
