Abstract

A method, device and system to set a power saving mode of for example a station to correspond to a power saving parameter that may be associated with a access category of a wireless packet in for example a uplink and a downlink of such station.

Claims

1. A method comprising setting a power saving parameter for a station in accordance with an access category in a link of said station.

2. The method as in claim 1, comprising recording access categories in said link of said station.

3. The method as in claim 1, comprising selecting a highest priority access category corresponding to said link.

4. The method as in claim 3, comprising identifying a timeout interval for said highest priority access category;

and identifying a snooze interval for said highest priority access category.

5. The method as in claim 4, comprising:

setting said station'"'"'s timeout intervals to correspond to said identified timeout intervals; and

setting said station'"'"'s snooze interval to correspond to said identified snooze interval.

6. The method as in claim 1, comprising selecting a highest priority access category in an interval of an uplink of said station and a highest priority access category in said interval for a downlink of said station.

7. The method as in claim 6, comprising:

selecting a longest transmit timeout interval from among

(i) a transmit timeout interval of said highest priority access category in said downlink and

(ii) a transmit timeout interval of said highest priority access category in said uplink; and

selecting a longest receive timeout interval from among

(i) a receive timeout interval of said highest priority access category in said downlink and

(ii) a receive timeout interval of said highest priority access category in said uplink.

8. The method as in claim 7, comprising selecting a snooze interval from among a shortest snooze interval of (i) the snooze interval of said highest priority access category in said downlink and (ii) the snooze interval of said highest priority access category in said uplink.

9. The method as in claim 8, comprising:

setting said station'"'"'s transmit timeout interval to said longest transmit timeout interval;

setting said station'"'"'s receive timeout interval to said longest receive timeout interval; and

setting said station'"'"'s snooze interval to said shortest snooze interval.

10. A device comprising:

a processor to set a power saving parameter of a station according to an access category corresponding to a link of said station.

11. The device as in claim 10, comprising a memory to record a highest priority access category in an interval of said link.

12. The device as in claim 10, wherein said processor is to select a highest priority access category in an interval of an uplink of said station and to select a highest priority access category in said interval for a downlink of said station

13. The device as in claim 12, wherein said processor is to coordinate a timeout interval for said station with a timeout interval associated with said highest priority access category in said interval of said uplink and with said highest priority access category in said interval of said downlink;

and wherein said processor is to coordinate a snooze interval for said station with a snooze interval associated with said highest priority access category of said uplink and with said highest priority access category in said interval for said downlink.

14. A system comprising:

a station;

a dipole antenna; and

a processor to set a power saving mode of the station to a power saving parameter associated with a highest priority access category in a link of wireless signals to said station.

15. The system as in claim 14, comprising a memory to record access categories present in a link of wireless signals during a relevant period.

16. The system as in claim 15, wherein said processor is to select a highest priority access category in said recorded access categories.

17. The system as in claim 16, wherein said processor is to coordinate a timeout interval for said station with a timeout interval associated with said highest priority access category in said relevant period of a uplink from said station and with said highest priority access category in said relevant period of a downlink to said station;

and wherein said processor is to coordinate a snooze interval for said station with a snooze interval associated with said highest priority access category of said uplink in said relevant period and with said highest priority access category of said downlink in said relevant period.

18. An article comprising a storage medium, having stored thereon instructions, that when executed, result in setting a power saving parameter for a station to correspond with an access category in a link of said station.

19. The article as in claim 18, wherein said instructions further result in identifying a timeout interval for a highest priority access category in said link;

and identifying a snooze interval for said highest priority access category.

20. The article as in claim 19, wherein said instructions further result in:

setting said station'"'"'s timeout interval to said identified timeout interval; and

setting said station'"'"'s snooze interval to said identified snooze interval.
