Abstract

An embodiment of the present invention provides a method of requesting bandwidth allocation in a wireless network, comprising using a partial bandwidth request by a mobile station (MS) operable in the wireless network to a base station (BS) operable in the wireless network, wherein the partial bandwidth request requests bandwidth for only a portion of all packets in an uplink (UL) queue.

Claims

1. A method of requesting bandwidth allocation in a wireless network, comprising:

using a partial bandwidth request by a mobile station (MS) operable in said wireless network to a base station (BS) operable in said wireless network, wherein said partial bandwidth request requests bandwidth for only a portion of all packets in an uplink (UL) queue.

2. The method of claim 1, wherein using said partial bandwidth request improves the chance of having a data transmission while a new packet is arriving so that a piggyback method can be used.

3. The method of claim 1, wherein said piggyback method allows said MS to send said bandwidth request message with a data transmission that has been allocated by said BS to said MS.

4. The method of claim 3, wherein said MS sets a grant size of said bandwidth request message to the total number of bytes in said UL queue so that it can transmit all the packets as soon as possible.

5. The method of claim 1, further comprising inserting a gap between packets to smooth out traffic and reduce jitter.

6. The method of claim 1, further comprising incorporating queue management to remove packets that have been successfully transmitted from said UL queue and also add packets that have newly arrived from an application into said UL queue.

7. The method of claim 1, wherein said wireless network is a network conforming to the Institute for Electrical and Electronic Engineers (IEEE) 802.16 standard.

8. A mobile station (MS), comprising:

a transceiver adapted for communication with a base station (BS) in a wireless network, said transceiver further adapted to request bandwidth allocation in said wireless network by using a partial bandwidth request to said BS, wherein said partial bandwidth request requests bandwidth for only a portion of all packets in an uplink (UL) queue.

9. The MS of claim 8, wherein using said partial bandwidth request improves the chance of having a data transmission while a new packet is arriving so that a piggyback method can be used to a maximum extent.

10. The MS of claim 8, wherein said piggyback method allows said MS to send said bandwidth request message with a data transmission that has been allocated by said BS to said MS.

11. The MS of claim 10, wherein said MS sets a grant size of said bandwidth request message to the total number of bytes in said UL queue so that it can transmit all the packets as soon as possible.

12. The MS of claim 8, further comprising said MS inserting a gap between packets to smooth out traffic and reduce jitter.

13. The MS of claim 8, further comprising incorporating queue management to remove packets that have been successfully transmitted from said UL queue and also add packets that have newly arrived from an application into said UL queue.

14. The MS of claim 8, wherein said wireless network is a network conforming to the Institute for Electrical and Electronic Engineers (IEEE) 802.16 standard.

15. A computer readable medium encoded with computer executable instructions, which when accessed, cause a machine to perform operations comprising:

using a partial bandwidth request by a mobile station (MS) operable in said wireless network to a base station (BS) operable in said wireless network, wherein said partial bandwidth request requests bandwidth for only a portion of all packets in an uplink (UL) queue.

16. The computer readable medium encoded with computer executable instructions of claim 15, wherein using said partial bandwidth request improves the chance of having a data transmission while a new packet is arriving so that a piggyback method can be used to a maximum extent.

17. The computer readable medium encoded with computer executable instructions of claim 15, wherein said piggyback method allows said MS to send said bandwidth request message with a data transmission that has been allocated by said BS to said MS.

18. The computer readable medium encoded with computer executable instructions of claim 17, wherein said MS sets a grant size of said bandwidth request message to the total number of bytes in said UL queue so that it can transmit all the packets as soon as possible.

19. The computer readable medium encoded with computer executable instructions of claim 15, further comprising further instructions which cause a machine to perform further operations comprising inserting a gap between packets to smooth out traffic and reduce jitter.

20. The computer readable medium encoded with computer executable instructions of claim 15, further comprising further instructions which cause a machine to perform further operations comprising, incorporating queue management to remove packets that have been successfully transmitted from said UL queue and also add packets that have newly arrived from an application into said UL queue.

21. The computer readable medium encoded with computer executable instructions of claim 15, wherein said wireless network is a network conforming to the Institute for Electrical and Electronic Engineers (IEEE) 802.16 standard.
