Patent ID: 7522637

Claim:
A dynamic resource allocation method for a multicarrier wireless communication system including at least one base station allocating resources to a plurality of subscriber stations (SSs) according to channel status information received from the plurality of SSs, comprising the steps of: determining if each of the plurality of SSs supports subchannel-based dynamic resource allocation; allocating resources to an SS on a subchannel basis, if the SS supports the subchannel-based dynamic resource allocation; and allocating resources to the SS on a burst basis, if the SS does not support the subchannel-based dynamic resource allocation; wherein allocating resources on the subchannel basis comprises the steps of: transmitting a second-type downlink MAP information element (DL-MAP IE) to the SS; receiving channel status information on the subchannel basis from the SS; and modulating and coding data for the SS on the subchannel basis according to the channel status information.
