1. CLAIMSWhat is claimed is:

  • 1. A method of assigning time-frequency resources in a wireless communication system, the method comprising;

    transmitting at least one region boundary to a mobile station, the at least one region boundary indicating a division of the time-frequency resources into at least two regions;

    determining a time-frequency resource assignment for the mobile station;

    transmitting an indication of the determined time-frequency resource assignment to the mobile station in a same region as the determined time-frequency resource; and

    transmitting a packet to the mobile station using the physical time-frequency resources corresponding to the determined time-frequency resource.2. The method of claim 1, further comprising transmitting an indication of at least one preferred region to the mobile station.3. The method of claim 1, wherein the wireless communication system is an orthogonal frequency division multiplexing based (OFDMA-based) system.4. The method of claim 1, wherein transmitting an indication of the determined time-frequency resource assignment to the mobile station in the same region as the determined time-frequency resource includes transmitting at least one of;

    a connection identifier;

    a region identifier;

    a channel identifier;

    a MIMO parameter identifier; and

    a modulation coding parameter identifier.5 The method of claim 1, wherein the at least two regions include a downlink region and an uplink region.6. The method of claim 1, wherein the at least two regions include a downlink partial usage of subcarriers (PUSC) region, a downlink full usage of subcarriers (FUSC) region, and an uplink PUSC region.7 The method of claim 1 , wherein the at least two regions further includes a downlink control region.8. The method of claim 7, further comprising transmitting an indication of the determined time-frequency resource assignment to a mobile station in the downlink control region.9. A method of receiving a radio resource assignment in a wireless communication system, the method comprising;

    receiving at least one region boundary indicating a division of the radio resources into at least two regions;

    processing a control channel in a first one of the at least two regions;

    receiving a radio resource assignment in the first one of the at least two regions;

    receiving a communication packet on the physical radio corresponding to the received time-frequency resource assignment in the first one of the at least two regions.10. The method of claim 9, further comprising receiving an indication of at least one preferred region.11. The method of claim 10, further comprising processing control channel resources only in the regions corresponding to the at least one preferred region.12. The method of claim 9, wherein the wireless communication system is an orthogonal frequency division multiplexing (OFDMA) based system.13. The method of claim 9, wherein the at least one region boundary, the radio resource assignment, and the communication packet are received from a base station.14. The method of claim 9, wherein the radio resources are time-frequency resources of an orthogonal frequency division multiplexing (OFDMA) based system.15. The method of claim 9, wherein the at least two regions comprise regions selected from the group consisting of a downlink partial usage of subcarriers (PUSC) region, a downlink full usage of subcarriers (FUSC) region, an uplink PUSC region, a control region, an uplink legacy region, and combinations.16. The method of claim 9, wherein receiving a radio resource assignment in the first one of the at least two regions includes receiving at least one of;

    a connection identifier;

    a region identifier;

    a channel identifier;

    a MIMO parameter identifier; and

    a modulation coding parameter identifier.17. A base station comprising;

    a processor;

    a computer readable medium storing programming for execution by the processor, the programming including instructions to;

    define a first region and a second region of time-frequency resources, including defining a boundary between the first region and the second region of time-frequency resources;

    direct the transmission of the definition of a first region and a second region of time-frequency resources to a mobile station during the first region of time-frequency resources;

    define a time-frequency resource assignment for the mobile station;

    direct the transmission of the definition of the time-frequency resource assignment to the mobile station during the first region of time-frequency resources; and

    direct the transmission of a communication packet to the mobile station using the physical time-frequency resources corresponding to the determined time-frequency resources during the first region of time-frequency resources.18. The base station of claim 17, wherein the processor is a collection of a plurality of processors working in concert. 19. The base station of claim 17, wherein defining a boundary between the first region and second region of time-frequency resources comprises identifying an OFDM symbol at which the boundary occurs.20. The base station of claim 17, wherein the second region of time-frequency resources is defined relative to the end of the first region of tie-frequency resources.
