Abstract

An electronic device is provided, which includes a housing, at least one wireless communication circuit located inside the housing and configured to: receive, from an AP device through a wireless medium, a target wake time (TWT) element indicating a TWT service period and a type of traffic that is associated with latency of the traffic; in response to receiving the TWT element, generate data frame associated with the type of traffic indicated by the TWT element; and transmit, to the AP device through the wireless medium, the data frame associated with the type of traffic during the TWT service period indicated by the TWT element.

First claim

What is claimed is:

1. An access point (AP) device for facilitating wireless communication, the AP device comprising:
one or more memories; and
one or more processors coupled to the one or more memories, the one or more processors configured to cause:
generating a target wake time (TWT) element including information indicating a type of traffic and a priority of the traffic, the information being determined based on latency for the traffic;
transmitting, to a non-AP device through a wireless medium, the TWT element; and
receiving, from the non-AP device through the wireless medium, data frame associated with the type of traffic indicated by the information during a TWT service period indicated by the TWT element.

2. The AP device of claim 1 , wherein the data frame associated with the type of traffic indicated by the information has a higher priority than data frame associated with other types of traffic during the TWT service period.

3. The AP device of claim 1 , wherein the type of traffic is associated with an access category, and the access category is a voice (VO), a video (VI), a best effort (BE), or a background (BK).

4. The AP device of claim 1 , wherein the information indicates one or more types of traffic.

5. The AP device of claim 1 , wherein the TWT element further includes a TWT identifier and a TWT service period.

6. The AP device of claim 1 , wherein the one or more processors are further configured to cause:
broadcasting a notice indicating that no access to the wireless medium is allowed by any non-AP devices other than the non-AP device during a period of time.

7. The AP device of claim 6 , wherein the period of time overlaps with the TWT service period.

8. A non-access point (AP) device for facilitating wireless communication, the non-AP device comprising:
one or more memories; and
one or more processors coupled to the one or more memories, the one or more processors configured to cause:
receiving, from an AP device through a wireless medium, a target wake time (TWT) element including information indicating a type of traffic and a priority of the traffic, the information being determined based on latency of the traffic;
in response to receiving the TWT element, transmitting data frame associated with the type of traffic indicated by the information during a TWT service period indicated by the TWT element through the wireless medium.

9. The non-AP device of claim 8 , wherein the data frame associated with the type of traffic indicated by the information has a higher priority than data frame associated with other types of traffic during the TWT service period.

10. The non-AP device of claim 8 , wherein the type of traffic is associated with an access category, and the access category is a voice (VO), a video (VI), a best effort (BE), or a background (BK).

11. The non-AP device of claim 8 , wherein the information indicates one or more types of traffic.

12. The non-AP device of claim 8 , wherein the TWT element further includes a TWT identifier and a TWT service period.

13. The non-AP device of claim 8 , wherein the one or more processors are further configured to cause:
receiving, from the AP device, a notice indicating that no access to the wireless medium is allowed by any non-AP devices other than the non-AP device during a period of time.

14. The non-AP device of claim 13 , wherein the period of time overlaps with the TWT service period.

15. A computer-implemented method of facilitating wireless communication, the method comprising:
receiving, from an AP device through a wireless medium, a target wake time (TWT) element including information indicating a type of traffic and a priority of the traffic, the information being determined based on latency of the traffic;
in response to receiving the TWT element, transmitting, to the AP device through the wireless medium, a data frame associated with the type of traffic indicated by the information during a TWT service period indicated by the TWT element.

16. The method of claim 15 , wherein the data frame associated with the type of traffic indicated by information has a higher priority than data frame associated with other types of traffic during the TWT service period.

17. The method of claim 15 , wherein the type of traffic is associated with an access category, and the access category is a voice (VO), a video (VI), a best effort (BE), or a background (BK).

18. The method of claim 15 , wherein further comprising:
receiving, from the AP device through the wireless medium, a notice indicating that no access to the wireless medium is allowed by any non-AP devices other than the non-AP device during a period of time.

19. The method of claim 18 , wherein the period of time overlaps with the TWT service period.

20. The method of claim 15 , wherein the information indicates one or more types of traffic.
