Hybrid automatic repeat request acknowledgement and upload multiuser operation

1. A method for transmitting hybrid automatic repeat request (HARQ) coded data by an access point, comprising:

receiving by the access point buffered frame information from a plurality of stations;

determining the HARQ coding information and resources for each of the plurality of stations;

transmitting a first trigger frame including the HARQ coding information and resource information for each of the plurality of stations, wherein the first trigger frame defines an extreme high throughput (EHT) SIG-C field length, and wherein the SIG-C field includes a HARQ unit information field, a first cyclic redundancy code (CRC) of the HARQ unit information field, control field with a length that allows time for an access point to prepare for the HARQ reception, and a second CRC of the control field;

receiving a first HARQ transmission from the plurality of stations; and

decoding the received HARQ transmission from the plurality of stations.

2. The method of claim 1 , further comprising transmitting a second trigger frame to request buffered frame information from the plurality of stations.

3. The method of claim 1 , wherein the buffered frame information includes the number of buffered frames and the length of each of the buffered frames.

4. The method of claim 1 , wherein the HARQ coding information includes the number of HARQ coding units and the length of each of the HARQ coding units.

5. The method of claim 1 , wherein the first trigger frame includes a common information field and user information fields for each station, where the user information fields are the same length and include a HARQ coding information field.

6. The method of claim 5 , wherein HARQ coding information field is padded with reserved values to fill the length of the user information field.

7. The method of claim 5 , wherein HARQ coding information field is filled with reserve values for a non-HARQ transmission from a station.

8. The method of claim 1 , wherein the first trigger frame includes a common information field and user information fields for each station, where the user information fields have lengths based upon a number of requested HARQ coding units.

9. The method of claim 1 , further comprising sending an acknowledgment for each of the transmissions from the stations.

10. The method of claim 1 , further comprising receiving a second HARQ transmission from each of the stations, and combining the first and second HARQ transmissions from each of the stations.

11. The method of claim 10 , wherein the first and second HARQ transmissions include the same HARQ coded information.

12. The method of claim 10 , wherein the first and second HARQ transmissions include different HARQ coded information.

13. A method for transmitting hybrid automatic repeat request (HARQ) coded data by a station, comprising:

receiving by the station a trigger frame specifying resources for the station;

determining HARQ coding information for buffered frames to be transmitted by the station; and

transmitting a first HARQ trigger based (TB) physical protocol data unit (PPDU), wherein a physical header of the HARQ TB PPDU includes a SIG-C field including the HARQ coding information, and wherein the SIG-C field includes a HARQ unit information field, cyclic redundancy code (CRC) of the HARQ unit information field, and a reserved field with a length that allows time for an access point to prepare for the HARQ reception.

14. The method of claim 13 , wherein the HARQ coding information includes the number of HARQ coding units and the length of each of the HARQ coding units.

15. The method of claim 13 , further comprising transmitting a second HARQ TB PPDU, wherein the first and second HARQ TB PPDU transmissions include the same HARQ coded information.

16. The method of claim 13 , further comprising transmitting a second HARQ TB PPDU, wherein the first and second HARQ TB PPDU transmissions include different HARQ coded information.

17. A method for transmitting hybrid automatic repeat request (HARQ) coded data by an access point, comprising:

transmitting a first trigger frame including resource information for each of the plurality of stations;

receiving by the access point HARQ coding information from a plurality of stations in a first HARQ trigger based (TB) physical protocol data unit (PPDU), wherein a header of the HARQ TB PPDU includes a SIG-C field including the HARQ coding information, and wherein the SIG-C field includes a HARQ unit information field, control field with a length that allows time for an access point to prepare for the HARQ reception, and a CRC of the HARQ unit information field and the control field;

transmitting a second trigger frame in response to the first HARQ TB PPDU;

receiving a second HARQ TB PPDU including HARQ coded information from the plurality of stations; and

decoding the received second HARQ TB PPDU from the plurality of stations.

18. The method of claim 17 , wherein the HARQ coding information includes the number of HARQ coding units and the length of each of the HARQ coding units.

19. The method of claim 17 , further comprising sending an acknowledgment to the second HARQ TB PPDU.

20. The method of claim 17 , further comprising receiving a third HARQ TB PPDU from each of the stations, and combining the second and third HARQ TB PPDUs from each of the stations.

21. The method of claim 20 , wherein the second and third HARQ TB PPDU include the same HARQ coded information.

22. The method of claim 20 , wherein the second and third HARQ TB PPDU include different HARQ coded information.
