Abstract

A subframe structure for wireless communication uses a master common subframe and second master common subframe method to give BSs different priorities to serve overlapping areas in common subframes. The subframe structure and corresponding method can increase overlapping cells'"'"' capacity and reduce interference.

Claims

1. A non-transitory computer readable medium encoding a subframe structure comprising a master and slave common subframe, wherein the subframe structure is configured to accommodate a base station in the master common subframe having priority over all of the other base stations in a wireless community that can communicate with subscriber stations in an overlapping area and, if a base station in a slave common subframe asks a base station in the master common subframe to decrease transmission power, the base station in the master common subframe following the indication.

2. The non-transitory computer readable medium of claim 1 wherein the subframe structure further comprises a master subframe, a secondary master subframe, and a slave subframe.

3. A wireless device comprising the non-transitory computer readable medium of claim 1.

4. A method for improving the service and reducing interference in wireless communication comprising using a common subframe including a master common subframe and a slave common subframe, wherein a base station in the master common subframe has priority over all of the other base stations in a wireless community that can communicate with subscriber stations in an overlapping area, and wherein if a base station in a slave common subframe asks a base station in the master common subframe to decrease transmission power, the base station in the master common subframe should follow the indication.

5. The method of claim 4 further comprising the use of a master subframe, a secondary master subframe, and a slave subframe.

6. A non-transitory computer readable medium encoding a subframe structure comprising a master common, second master common, and a slave common subframe, wherein the subframe structure is configured to accommodate a base station in the second master common subframe having priority over all of the other base stations in a wireless community that can communicate with subscriber stations in an overlapping area except for a base station in the master common subframe and, if a base station in a slave common subframe asks a base station in the second master common subframe to decrease transmission power, the base station in the second master common subframe following the indication.

7. The non-transitory computer readable medium of claim 6 wherein the subframe structure further comprises a master subframe, a secondary master subframe, and a slave subframe.

8. A wireless device comprising the non-transitory computer readable medium of claim 6.

9. A method for improving the service and reducing interference in wireless communication comprising using a common subframe including a master common, a second master common, and a slave common subframe, wherein a base station in the second master common subframe has priority over all of the other base stations in a wireless community that can communicate with subscriber stations in an overlapping area except for a base station in the master common subframe, and wherein if a base station in a slave common subframe asks a base station in the second master common subframe to decrease transmission power, the base station in the second master common subframe should follow the indication.

10. The method of claim 9 further comprising the use of a master subframe, a secondary master subframe, and a slave subframe.

11. A non-transitory computer readable medium encoding a subframe structure comprising a master and slave common subframe, wherein the subframe structure is configured to accommodate a base station in the master common subframe having priority over all of the other base stations in a wireless community that can communicate with subscriber stations in an overlapping area and, if a base station in a slave common subframe asks a base station in the master common subframe to use a slave common subframe, the base station in the master common subframe following the indication.

12. The non-transitory computer readable medium of claim 11 wherein the subframe structure further comprises a master subframe, a secondary master subframe, and a slave subframe.

13. A wireless device comprising the non-transitory computer readable medium of claim 11.

14. A method for improving the service and reducing interference in wireless communication comprising using a common subframe including a master common subframe and a slave common subframe, wherein a base station in the master common subframe has priority over all of the other base stations in a wireless community that can communicate with subscriber stations in an overlapping area, and wherein if a base station in a slave common subframe asks a base station in the master common subframe to use a slave common subframe, the base station in the master common subframe should follow the indication.

15. The method of claim 14 further comprising the use of a master subframe, a secondary master subframe, and a slave subframe.

16. A non-transitory computer readable medium encoding a subframe structure comprising a master common, second master common, and a slave common subframe, wherein the subframe is configured to accommodate a base station in the second master common subframe having priority over all of the other base stations in a wireless community that can communicate with subscriber stations in an overlapping area except for a base station in the master common subframe and, if a base station in a slave common subframe asks a base station in the second master common subframe to use a slave common subframe, the base station in the master common subframe following the indication.

17. The non-transitory computer readable medium of claim 16 wherein the subframe structure further comprises a master subframe, a secondary master subframe, and a slave subframe.

18. A wireless device comprising the non-transitory computer readable medium of claim 16.

19. A method for improving the service and reducing interference in wireless communication comprising using a common subframe including a master common, a second master common, and a slave common subframe, wherein a base station in the second master common subframe has priority over all of the other base stations in the wireless community that can communicate with subscriber stations in an overlapping area except for a base station in the master common subframe, and wherein if a base station in a slave common subframe asks a base station in the second master common subframe to use a slave common subframe, the base station in the master common subframe should follow the indication.

20. The method of claim 19 further comprising the use of a master subframe, a secondary master subframe, and a slave subframe.
