Abstract

A method and system for allocating shareable wireless transmission resources. A resource pool is established. The resource pool is divided into a plurality of physical layer allocation units usable for wirelessly transmitting control information and traffic data. The allocation units are assigned at the media access control layer for the wireless transmission of the control information and traffic data. The system and method of the present invention also allows mobile stations to be dynamically grouped into multicast groupings to reduce system overhead resource requirements.

First claim

What is claimed is:

1. A method for receiving mobile station-specific control information within a multicast group, the method comprising:
a mobile station transmitting signaling to a base station causing the mobile station to automatically join a first multicast group based on a layer commonality associated with the signaling and without the mobile station receiving signaling to create or update the multicast group, wherein the first multicast group is defined by a first multicast group ID, wherein the first multicast group is defined by the base station temporarily grouping mobile stations sharing the layer commonality;
receiving control signaling associated with the first multicast group ID indicating a resource location for a physical burst transmission; and
the mobile station receiving a multicast group control message from the base station via multicasting to the first multicast group ID in the physical burst transmission associated with the first multicast group ID comprising the mobile station-specific control information, wherein the physical burst transmission comprises control information for a plurality of mobile stations, wherein the mobile station-specific control information comprises an identifier corresponding specifically to the mobile station and information corresponding specifically to the mobile station, and wherein the mobile station-specific control information is unicast information transmitted within a multicast message and wherein the mobile station disregards multicast group control messages associated with multicast groups defined by second multicast group IDs other than the first multicast group ID.

2. The method of claim 1 , wherein the layer commonality is a layer 1 commonality.

3. The method of claim 1 , wherein the layer commonality is a layer 2 commonality.

4. The method of claim 1 , wherein defining the first multicast group includes:
predefining a multicast group ID for each of at least one supported service; and
including the mobile station having a supported service as part of a predefined multicast group having a corresponding multicast group ID.

5. The method of claim 1 , further comprising:
receiving resource allocation signaling to allocate resources to the mobile station in the first multicast group.

6. The method of claim 5 , wherein the resource allocation signaling allocates resources to all mobile stations in the first multicast group without specifying the mobile stations in the first multicast group, the mobile stations in the first multicast group being known from previous signaling.

7. The method of claim 5 , wherein the resource allocation signaling allocates resources to selected mobile stations in the first multicast group by setting a respective flag associated with each mobile station in the first multicast group.

8. The method of claim 1 , wherein mobile station can participate in a plurality of multicast groups.

9. The method of claim 1 , wherein the method is applied to a wireless protocol selected from one of an evolution data-only (EV-DO), Universal Mobile Telecommunications System (UMTS), code division multiple access (CDMA), orthogonal frequency division multiplexing (OFDM), broadband OFDM (B-OFDM), broadband OFDM multiple input multiple output (B-OFDM-MIMO) and a 3rd Generation Partnership Project 3GPP protocol.

10. A non-transitory, computer accessible memory medium storing program instructions for receiving mobile station-specific control information within a multicast group, wherein the program instructions are executable by a processor of a mobile station to:
transmit signaling to a base station causing the mobile station to automatically join a first multicast group based on a layer commonality associated with the signaling and without the mobile station receiving signaling to create or update the multicast group, wherein the first multicast group is defined by a first multicast group ID, wherein the first multicast group is defined by the base station temporarily grouping mobile stations sharing the layer commonality;
receive control signaling associated with the first multicast group ID indicating a resource location for a physical burst transmission; and
receive a multicast group control message from the base station via multicasting to the first multicast group ID in the physical burst transmission associated with the first multicast group ID comprising the mobile station-specific control information, wherein the physical burst transmission comprises control information for a plurality of mobile stations, wherein the mobile station-specific control information comprises an identifier corresponding specifically to the mobile station and information corresponding specifically to the mobile station, and wherein the mobile station-specific control information is unicast information transmitted within a multicast message and wherein the mobile station disregards multicast group control messages associated with multicast groups defined by second multicast group IDs other than the first multicast group ID.

11. The non-transitory, computer accessible memory medium of claim 10 , wherein the layer commonality is a layer 1 commonality.

12. The non-transitory, computer accessible memory medium of claim 10 , wherein the layer commonality is a layer 2 commonality.

13. The non-transitory, computer accessible memory medium of claim 10 , wherein defining the first multicast group includes:
predefining a multicast group ID for each of at least one supported service; and
including the mobile station having a supported service as part of a predefined multicast group having a corresponding multicast group ID.

14. The non-transitory, computer accessible memory medium of claim 10 , wherein the program instructions are further executable to:
receive resource allocation signaling to allocate resources to the mobile station in the first multicast group.

15. The non-transitory, computer accessible memory medium of claim 14 , wherein the resource allocation signaling allocates resources to all mobile stations in the first multicast group without specifying the mobile stations in the first multicast group, the mobile stations in the first multicast group being known from previous signaling.

16. The non-transitory, computer accessible memory medium of claim 14 , wherein the resource allocation signaling allocates resources to selected mobile stations in the first multicast group by setting a respective flag associated with each mobile station in the first multicast group.

17. The non-transitory, computer accessible memory medium of claim 10 , wherein mobile station can participate in a plurality of multicast groups.

18. The non-transitory, computer accessible memory medium of claim 10 , wherein the mobile station is configured to communicate using one of an evolution data-only (EV-DO), Universal Mobile Telecommunications System (UMTS), code division multiple access (CDMA), orthogonal frequency division multiplexing (OFDM), broadband OFDM (B-OFDM), broadband OFDM multiple input multiple output (B-OFDM-MIMO) and a 3rd Generation Partnership Project 3GPP protocol.

19. A mobile station configured to receive mobile station-specific control information within a multicast group, the mobile station comprising:
communication circuitry, wherein the communication circuitry is configured to perform wireless communication; and
processing hardware coupled to the communication circuitry, wherein the processing hardware is configured to operate with the communication circuitry to:
transmit signaling to a
