1. A method of portioning wireless transmission resources, the method comprising:

at a base station:

establishing an uplink resource pool in a first time interval, the uplink resource pool being divided into a plurality of physical layer allocation units usable for wirelessly transmitting control and traffic data from mobile stations; wherein the physical layer of the uplink is based on a broadband orthogonal frequency domain multiplexing (OFDM) technology;

partitioning the allocation units of the uplink resource pool, wherein the resource partitioning is a temporary arrangement transmitted in at least one system information message, wherein the resource partitioning configuration includes at least partitions of:

one or more feedback partitions configurable to receive at least channel quality feedback, feedback related to multiple input multiple output (MIMO) operation, and hybrid automatic repeat request (HARD) feedback at the base station from one or more mobile stations; and

a first signaling partition configurable to receive signaling at the base station from one or more mobile stations, where the signaling is used for at least performing a uplink timing adjustment for mobile station transmissions;

adding a mobile station to a first multicast group based on a common parameter, wherein the first multicast group is defined by a first multicast group ID, wherein the first multicast group ID is defined by the base station for temporarily grouping mobile stations sharing the common parameter and a particular packet type, service, or mobile station state;

transmitting an uplink resource assignment specific to the mobile station in a multicast control message, wherein the multicast control message is directed to the first multicast group defined by the first multicast group ID, wherein the multicast control message identifies a plurality of mobile stations of the first multicast group that are each assigned respective resources; and

transmitting a second uplink resource assignment in a second multicast control message, wherein a second multicast control message is directed to a second multicast group is defined by a second multicast group ID, wherein the mobile station is not a member of the second multicast group, wherein the second multicast group ID is used to prevent the mobile station from decoding the second multicast control message.

2. The method of claim 1 , wherein the at least one system information message is broadcast on at least every N radio frames, wherein N is an integer.

3. The method of claim 1 , wherein the at least one system information message further comprises a sector ID, geographic information, and neighbor information.

4. The method of claim 1 , wherein the resource partitioning configuration further comprises a resource pool for uplink messages and traffic to the base station.

5. The method of claim 4 , wherein the resource pool for uplink messages and traffic to the base station is the remainder of uplink resources not included in the one or more feedback partitions and the first signaling partition in the first time interval.

6. The method of claim 4 , wherein the uplink resource assignment and the second uplink resource assignment are reassignable each time interval.

7. The method of claim 6 , wherein uplink resource assignments are on an on demand basis and for one or more time intervals.

8. The method of claim 1 , further comprising:

establishing a downlink resource pool in the first time interval, the downlink resource pool being divided into a plurality of physical layer downlink allocation units usable for wirelessly transmitting downlink control information and downlink traffic data, wherein the physical layer of the downlink is based on a broadband OFDM technology; and

assigning downlink allocation units for the wireless transmission of the downlink control information and downlink traffic data, wherein the downlink allocation units are arranged into time intervals, wherein the assigned downlink allocation units are reassignable each time interval.

9. The method of claim 8 , further comprising:

reserving a predetermined quantity of downlink allocation units for a portion of the downlink control information defining how an interval is decoded.

10. A method of receiving a configuration of wireless transmission resources, the method comprising:

at a mobile station:

receiving at least one system information message from a base station comprising resource partitioning of an uplink resource pool in a first time interval, wherein the uplink resource pool is divided into a plurality of physical layer allocation units usable for wirelessly transmitting control and traffic data from mobile stations, wherein the physical layer of the uplink is based on a broadband orthogonal frequency domain multiplexing (OFDM) technology, wherein the resource partitioning of the allocation units of the uplink resource pool, wherein the resource partitioning configuration comprises at least partitions of:

one or more feedback partitions configurable to receive at least channel quality feedback, feedback related to multiple input multiple output (MIMO) operation, and hybrid automatic repeat request (HARD) feedback at a base station from one or more mobile stations; and

a first signaling partition configurable to receive signalling at the base station from one or more mobile station, where the signalling is used for at least performing a uplink timing adjustment for mobile station transmissions;

joining a first multicast group based on a common parameter, wherein the first multicast group is defined by a first multicast group ID, wherein the first multicast group ID is defined for temporarily grouping mobile stations sharing the common parameter and a particular packet type, service type, or mobile station state;

receiving an uplink resource assignment specific to the mobile station in a multicast control message, wherein the multicast control message is directed to the first multicast group defined by the first multicast group ID, wherein the multicast control message identifies a plurality of mobile stations of the first multicast group that are each assigned respective resources; and

not decoding a second uplink resource assignment in a second multicast control message, wherein a second multicast control message is directed to a second multicast group defined by a second multicast group ID, wherein the second multicast group ID prevents the mobile station from decoding the second multicast control message.

11. The method of claim 10 , wherein the at least one system information message is broadcast on at least every N radio frames, wherein N is an integer.

12. The method of claim 10 , wherein the at least one system information message further comprises a sector ID, geographic information, and neighbor information.

13. The method of claim 10 , wherein the resource partitioning configuration further comprises a resource pool for uplink messages and traffic to the base station.

14. The method of claim 13 , wherein the resource pool for uplink messages and traffic to the base station is the remainder of uplink resources not included in the one or more feedback partitions and the first signaling partition in the first time interval.

15. The method of claim 13 , wherein the uplink resource assignment and the second uplink resource assignment are reassignable each time interval.
