Abstract

A method and device for wireless communication are provided. A latency-sensitive transmission first mode corresponding to a station (STA) is enabled by the STA and notified to the AP.

First claim

What is claimed is:

1 . A wireless communication method, comprising: enabling, by a station (STA), a latency-sensitive transmission prioritized mode corresponding to the STA and notifying, by the STA, enablement of the latency-sensitive transmission prioritized mode corresponding to the STA to an access point (AP).

2 . The method according to claim 1 , comprising:
receiving, by the STA, a first trigger frame, wherein the first trigger frame comprises a first field, the first field indicates to the STA to reserve, in at least one uplink transmission, frequency-domain units for reporting buffer information of low-latency traffic, and the at least one uplink transmission comprises a first uplink transmission, or the first field indicates to the STA to reserve, in an uplink transmission in a first transmission opportunity (TXOP), frequency-domain units for reporting buffer information of low-latency traffic, and the uplink transmission in the first TXOP is a first uplink transmission.

3 . The method according to claim 2 , wherein
the first TXOP is a TXOP obtained by the STA, or the first TXOP is a TXOP obtained by a AP.

4 . The method according to claim 2 , wherein the first uplink transmission is an uplink response or uplink acknowledgment to downlink transmission executed by the AP after the AP obtains the TXOP.

5 . The method according to claim 4 , wherein the uplink response or uplink acknowledgment is executed through a block acknowledgment (BA) frame.

6 . The method according to claim 2 , wherein the low-latency traffic is identified by restricted target wake time (R-TWT) identifier (TID) or stream classification service identifier (SCS ID).

7 . The method according to claim 1 , wherein the latency-sensitive transmission prioritized mode corresponding to the STA is enabled based on a request from the AP.

8 . The method according to claim 1 , wherein a duration of the latency-sensitive transmission prioritized mode corresponding to the STA is configured by the AP in request information.

9 . The method according to claim 1 , wherein a duration of the latency-sensitive transmission prioritized mode corresponding to the STA is indicated by the STA in notification information.

10 . The method according to claim 9 , wherein the notification information comprises a management frame.

11 . The method according to claim 1 , wherein in the case where the AP has enabled the latency-sensitive transmission prioritized mode, the STA learns that the AP has enabled the latency-sensitive transmission prioritized mode through at least one of the following frames sent by the AP: a beacon frame, a probe response frame, an association response frame, a re-association response frame, and an operation mode notification frame.

12 . The method according to claim 11 , wherein the following is indicated by the AP while the AP indicating that the AP has enabled the latency-sensitive transmission prioritized mode: a duration of the latency-sensitive transmission prioritized mode corresponding to the AP.

13 . The method according to claim 11 , wherein enabling and/or disabling of the latency- sensitive transmission prioritized mode corresponding to the AP is associated with transmission information of low-latency traffic in a basic service set (BSS).

14 . The method according to claim 11 , wherein enabling and/or disabling of the latency-sensitive transmission prioritized mode corresponding to the AP is set via user signaling.

15 . A station (STA), comprising:
a transceiver; a processor; and a memory storing computer readable programs which, when executed by the processor, are operable with the processor to:
enable a latency-sensitive transmission prioritized mode corresponding to the STA and notify, through the transceiver, enablement of the latency-sensitive transmission prioritized mode corresponding to the STA to an access point (AP).

16 . The STA according to claim 15 , wherein the processor is further configured to: in the case where the AP has enabled the latency-sensitive transmission prioritized mode, cause the transceiver to receive at least one of the following frames sent by AP, for the STA to learn that the AP has enabled a latency-transmission prioritized mode: a beacon frame, a probe response frame, an association response frame, a re-association response frame, and an operation mode notification frame.

17 . The STA according to claim 15 , wherein a latency-sensitive transmission prioritized mode corresponding to the STA is enabled based on a request from the AP.

18 . The STA according to claim 15 , wherein a duration of the latency-sensitive transmission prioritized mode corresponding to the STA is configured by the AP in request information.

19 . The STA according to claim 15 , wherein a duration of the latency-sensitive transmission prioritized mode corresponding to the STA is indicated by the STA in notification information.

20 . The STA according to claim 19 , wherein the notification information comprises a management frame.
