1. Claimsa kind of data transmission method for uplink, it is characterised in that including:

  • According to a group media access control protocol data unit G-MPDU length, one or more media access control protocol data unit MPDU is encapsulated as G-MPDU;

    When residue length is not enough to encapsulate current MPDU, burst is carried out to current MPDU according to the residue length, the MPDU of burst is obtained;

    The MPDU ^ " of the burst are filled to the G-MPDU;

    Send packaged G-MPDU.2. the method as described in claim 1, it is characterised in that:

    When residue length is not enough to encapsulate current MPDU, first judge whether the residue length is more than default minimum burst length, if it does, just performing burst processing to current MPDU, otherwise, burst processing is not performed, G-MPDU encapsulation terminates.3. the method as described in claim 1, it is characterised in that:

    Each MPDU is encapsulated as to G-MPDU subframe, including:

    Delimiter is set before the MPDU;

    Filler is set after the MPDU, to cause the length of the subframe as the integral multiple of 2 bytes.4. method as claimed in claim 3, it is characterised in that:

    The delimiter is made up of delimiter mark and length check information.5. the method as described in claim 1, it is characterised in that:

    When encapsulating G-MPDU, the MPDU of preferential encapsulation burst.6. the method as described in claim 1, it is characterised in that:

    For the MPDU of the burst, burst number is set.7. method as claimed in claim 6, it is characterised in that:

    For the MPDU of the burst, burst configured information is set.8. method as claimed in claim 7, it is characterised in that:

    The burst configured information is used for behind instruction the burst for also having current MPDU.9. the method as described in claim 1, it is characterised in that:

    The length of the G-MPDU is determined according to the transfer resource currently distributed.10. a kind of data receiver method, it is characterised in that including:

    Receive and parse through a group media access control protocol data unit G-MPDU;

    Wherein, the G-MPDU is included equipped with a MPDU in one or more subframe, each subframe, and the MPDU is the MPDU of the burst or MPDU of non-burst;

    The MPDU of the burst of the same sequence number parsed is recombinated.11. method as claimed in claim 10, it is characterised in that:

    Parse after MPDU, it is just blunt according to traffic identifier FID, the MPDU of non-burst is put into the corresponding Slow of the FID and rushes window;

    The MPDU of burst is put into the corresponding burst Slow of the FID and rushes area, the MPDU of the burst of same sequence number is recombinated, putting it into the corresponding Slow of the FID after the MPDU for recovering non-burst rushes window;

    The Slow, which is sent, to upper strata rushes the MPDU that Slow in window is deposited.12. method as claimed in claim 10, it is characterised in that:

    It is just blunt according to burst number, the MPDU of all bursts of same sequence number is recombinated successively, the MPDU of non-burst is recovered.13. method as claimed in claim 12, it is characterised in that:

    According to the burst for whether also having current MPDU behind the determination of burst configured information.14. method as claimed in claim 10, it is characterised in that:

    Delimiter is also packaged with each subframe;

    The original position of the MPDU in subframe is oriented according to the delimiter;

    To the MPDU parsings in the subframe oriented.15. method as claimed in claim 14, it is characterised in that:

    After the original position for orienting MPDU in subframe, the length of the MPDU is obtained, the MPDU encapsulated in next subframe original position is oriented by calculating.16. a kind of data sending device, it is characterised in that including:

    Package module, for just blunt according to a group media access control protocol data unit G-MPDU length, G-MPDU is encapsulated as by one or more media access control protocol data unit MPDU;

    When residue length is not enough to encapsulate current MPDU, burst is carried out to current MPDU according to the residue length, the MPDU of burst is obtained;

    The MPDU ^ " of the burst are filled to the G-MPDU;

    Sending module, the packaged G-MPDU for sending.17. device as claimed in claim 16, it is characterised in that:

    The package module, when residue length is not enough to encapsulate current MPDU, first judges whether the residue length is more than default minimum burst length, if it does, just performing burst processing to current MPDU, otherwise, burst processing is not performed, and G-MPDU encapsulation terminates.18. device as claimed in claim 16, it is characterised in that:

    The package module, the subframe for each MPDU to be encapsulated as to G-MPDU, including:

    Delimiter is set before the MPDU;

    Filler is set after the MPDU, to cause the length of the subframe as the integral multiple of 2 bytes.19. device as claimed in claim 18, it is characterised in that:

    The delimiter is made up of delimiter mark and length check information.20. device as claimed in claim 16, it is characterised in that:

    The package module, when encapsulating G-MPDU, the MPDU of preferential encapsulation burst.21. device as claimed in claim 16, it is characterised in that:

    The package module, is additionally operable to set burst number for the MPDU of the burst.22. device as claimed in claim 21, it is characterised in that:

    The package module, is additionally operable to set burst configured information for the MPDU of the burst.23. device as claimed in claim 22, it is characterised in that:

    The burst configured information is used for behind instruction the burst for also having current MPDU.24. device as claimed in claim 16, it is characterised in that:

    The length of the G-MPDU is determined according to the transfer resource currently distributed.25. a kind of data sink, it is characterised in that including:

    Parsing module is received, for receiving and parsing through a group media access control protocol data unit G-MPDU;

    Wherein, the G-MPDU is included equipped with a MPDU in one or more subframe, each subframe, and the MPDU is the MPDU of the non-burst of MPDU or ^ of burst;

    Processing module, the MPDU for the burst of the same sequence number to parsing is recombinated.26. device as claimed in claim 25, it is characterised in that:

    The processing module, it is just blunt according to traffic identifier FID for after the reception parsing module parses MPDU, the MPDU of non-burst is put into the corresponding Slow of the FID and rushes window;

    The MPDU of burst is put into the corresponding burst Slow of the FID and rushes area, the MPDU of the burst of same sequence number is recombinated, putting it into the corresponding Slow of the FID after the MPDU for recovering non-burst rushes window;

    The Slow, which is sent, to upper strata rushes the MPDU that Slow in window is deposited.27. device as claimed in claim 25, it is characterised in that:

    The processing module, for according to burst number, being recombinated successively to the MPDU of all bursts of same sequence number, recovering the MPDU of non-burst.28. device as claimed in claim 27, it is characterised in that:

    The processing module, for according to the burst for whether also having current MPDU behind the determination of burst configured information.29. device as claimed in claim 25, it is characterised in that:
