Abstract

A wireless network (100) includes a plurality of wireless stations (QSTAs) (102) and an access point (QAP) (101). The QAP, or one or more of the QSTAs, or both, are adapted to measure delay data, or queue data, or both, per one or more traffic type. A method of wireless communication is also described.

Claims

1. A wireless network (100), comprising:

a plurality of wireless stations (QSTAs) (102); and

an access point (QAP) (101), wherein the QAP, or one or more of the QSTAs, or both, are adapted to measure delay data, or queue data, or both, per one or more traffic type, or per QSTA.

2. The wireless network of claim 1, wherein the one or more traffic types include:

an access category, a traffic stream, or a user priority.

3. The wireless network of claim 1, wherein the delay data are one or more of:

an average delay (301), a maximum delay (302), a minimum delay (303), a standard deviation of the delay (304), a variance of the delay (305), or a histogram of the delay (306).

4. The wireless network of claim 1, wherein each of the QSTAs is adapted to make a request for the delay data.

5. The wireless network of claim 1, wherein each of the QSTAs is adapted to make a request for the queue data.

6. The wireless network of claim 1, wherein each of the QSTAs is adapted to report the delay data.

7. The wireless network of claim 1, wherein each of the QSTAs is adapted to report the queue data

8. The wireless network of claim 1, wherein the QAP is adapted to make a request for the delay data.

9. The wireless network of claim 1, wherein the QAP is adapted to make a request for the queue data.

10. The wireless network of claim 1, the QAP is adapted to report the delay data.

11. The wireless network of claim 1, wherein the QAP is adapted to report the queue data.

12. The wireless network claim 1, wherein the queue data are one or more of:

an average queue length (307), a maximum queue length (308), a minimum queue length (309), a standard deviation of a queue length (310), a variance of a queue length (311), or a histogram of queue length data (312).

13. A method of wireless communication, the method comprising:

measuring delay data, or queue data, or both (202), per one or more traffic type, or per wireless station (QSTA)(102); and

, if necessary, taking an action based on the data.

14. The method of claim 13, wherein the one or more traffic types include:

an access category, a traffic stream, or a user priority.

15. The method of claim 13, wherein the delay data are one or more of:

an average delay (301), a maximum delay (302), a minimum delay (303), a standard deviation of the delay (304), a variance of the delay (305), or a histogram of the delay (306).

16. The method of claim 13, the method further comprising:

providing a plurality of wireless stations (QSTAs) and an access point (QAP)(101); and

requesting delay data from the QSTA by the QAP.

17. The method of claim 13, the method further comprising providing a plurality of wireless stations (QSTAs) and access point (QAP);

and

requesting queue data from the QSTA by the QAP.

18. The method of claim 13, the method further comprising:

providing a plurality of wireless stations (QSTAs) and access point (QAP); and

reporting the delay data by the QAP to the QSTA.

19. The method of claim 13, the method further comprising:

providing a plurality of wireless stations (QSTAs) and access point (QAP); and

reporting the queue data by the QAP to the QSTA.

20. The wireless network claim 13, wherein the queue data are one or more of:

an average queue length (307), a maximum queue length (308), a minimum queue length (309), a standard deviation of a queue length (310), a variance of a queue length (311), or a histogram of queue length data (312).
