Abstract

A wireless network includes base stations and mobile stations. The base stations determine burst sizes and partitions, and signal this information to the mobile stations.

Claims

1. A method comprising:

populating a download (DL) MAP information element (IE) with a first field indicative of a number of logical resource units (LRUs) allocated for a download burst partition;

populating the DL MAP IE with a second field that represents a size offset to be used by a mobile station to determine a size of the download burst partition; and

transmitting the DL MAP IE to the mobile station.

2. The method of claim 1 wherein the second field is five bits in length.

3. The method of claim 1 further comprising transmitting to the mobile station at least one burst of data in the download burst partition.

4. The method of claim 3 further comprising transmitting multiple forward error correction (FEC) blocks when the size of the download burst partition is greater than 600 bytes.

5. A method comprising:

populating an upload (UL) MAP information element (IE) with a first field indicative of a number of logical resource units (LRUs) allocated for an upload burst partition;

populating the UL MAP IE with a second field that represents a size offset to be used by a mobile station to determine a size of the upload burst partition; and

transmitting the UL MAP IE to the mobile station.

6. The method of claim 5 wherein the second field is five bits in length.

7. The method of claim 5 further comprising receiving from the mobile station at least one burst of data in the upload burst partition.

8. A method comprising:

receiving a download (DL) MAP information element (IE);

reading from the DL MAP IE a first field indicative of a number of logical resource units (LRUs) allocated for a download burst partition;

reading from the DL MAP IE a second field that represents a size offset; and

determining a size of the download burst partition by indexing into a table using the number of LRUs allocated and the size offset.

9. The method of claim 8 wherein the second field is five bits in length.

10. The method of claim c further comprising receiving at least one burst of data in the download burst partition.

11. The method of claim 10 further comprising receiving multiple forward error correction (FEC) blocks when the size of the download burst partition is greater than 600 bytes.

12. A method comprising:

receiving an upload (UL) MAP information element (IE);

reading from the UL MAP IE a first field indicative of a number of logical resource units (LRUs) allocated for an upload burst partition;

reading from the DL MAP IE a second field that represents a size offset; and

determining a size of the upload burst partition by indexing into a table using the number of LRUs allocated and the size offset.

13. The method of claim 12 wherein the second field is five bits in length.

14. The method of claim 12 further comprising transmitting at least one burst of data in the upload burst partition.

15. The method of claim 14 further comprising transmitting multiple forward error correction (FEC) blocks when the size of the upload burst partition is greater than 600 bytes.

16. A method comprising:

designing a list of burst sizes;

selecting a minimal burst size according to allocation size; and

selecting a burst size by an offset to the minimal size.

17. The method of claim 16 further comprising signaling the burst size to a mobile station.

18. The method of claim 16 wherein signaling the burst size comprises:

populating fields in a download (DL) MAP information element (IE); and

transmitting the DL MAP IE to a mobile station.

19. The method of claim 16 wherein signaling the burst size comprises:

populating fields in an upload (UL) MAP information element (IE); and

transmitting the UL MAP IE to a mobile station.

20. A computer-readable medium having instructions stored thereon that when accessed result in a mobile station performing:

determining a burst size index as where is derived from a number of logical resource units (LRUs) allocated to a burst, and is a five bit index retrieved from an MAP information element (IE) in an IEEE 802.16 compliant system; and

determining a burst size by indexing into a table using the burst size index.

21. The computer-readable medium of claim 20 wherein the MAP IE comprises a download (DL) MAP IE, and the burst size corresponds to a size of a download burst.

22. The computer-readable medium of claim 20 wherein the MAP IE comprises an upload (UL) MAP IE, and the burst size corresponds to a size of an upload burst.

23. A mobile station comprising:

at least one antenna;

a physical layer coupled to the at least one antenna to receive MAP information elements (IEs) from a base station, the physical layer operable to determines a burst partition size using a five bit offset retrieved from the MAP IEs.

24. The mobile station of claim 23 wherein the physical layer is further operable to include multiple forward error correction (FEC) blocks of equal size for bursts greater than 600 bytes.

25. A mobile station comprising:

at least one antenna;

a physical layer coupled to the at least one antenna, wherein the physical layer supports a set of burst sizes that are within a range of minimal spectral efficiency to maximal spectral efficiency for all allocation sizes.

26. The mobile station of claim 25 wherein the physical layer is capable of adaptive Hybrid Automatic Repeat reQuest (HARM) in which original transmissions and re-transmissions have common burst sizes and different allocation sizes.

27. The mobile station of claim 25 further comprising a media access control layer to determine the burst sizes.
