Abstract

Provided is a method for wireless communication. The method is performed by a station (STA) having uplink (UL) data to be transmitted, and includes: transmitting a first medium access control (MAC) frame, wherein the first MAC frame is configured for channel contention, and a channel contention result corresponding to the first MAC frame is associated with grouping information of the STA.

First claim

1 . A method for wireless communication, performed by a station (STA) having uplink (UL) data to be transmitted, the method comprising:
transmitting a first medium access control (MAC) frame, wherein the first MAC frame is configured for channel contention, and a channel contention result corresponding to the first MAC frame is associated with grouping information of the STA.

2 . The method according to claim 1 , wherein the grouping information of the STA comprises at least one of:
information indicating whether the STA belongs to an STA group in m STA groups; or an identifier (ID) of an STA group to which the STA belongs and/or a number of STAs in the STA group to which the STA belongs in a case where the STA belongs to an STA group in m STA groups; wherein the m STA groups are pre-assigned, m is a positive integer, and m=1 or m≥2.

3 . The method according to claim 1 , wherein that the channel contention result corresponding to the first MAC frame is associated with the grouping information of the STA comprises:
in a case where the STA belongs to a first STA group in m STA groups, and a number of STAs in the first STA group is less than a first threshold, a transmission opportunity (TXOP) associated with the channel contention corresponding to the first MAC frame belongs to the STA; and/or in a case where the STA belongs to a first STA group in m STA groups, and a number of STAs in the first STA group is greater than or equal to a first threshold, a TXOP associated with the channel contention corresponding to the first MAC frame belongs to an access point (AP); and/or in a case where the STA does not belong to any STA group in m STA groups, a TXOP associated with the channel contention corresponding to the first MAC frame belongs to the STA; wherein the m STA groups are pre-assigned, m is a positive integer, and m=1 or m≥2.

4 . The method according to claim 3 , wherein in a case where the TXOP associated with the channel contention corresponding to the first MAC frame belongs to the AP, part or all of the STAs in the first STA group transmit UL data within the TXOP upon receiving a trigger frame from the AP.

5 . The method according to claim 3 , wherein in a case where the TXOP associated with the channel contention corresponding to the first MAC frame belongs to the AP, part or all of the STAs in the first STA group transmit UL data and receive downlink (DL) data within the TXOP upon receiving a trigger frame from the AP.

6 . The method according to claim 3 , wherein in a case where the TXOP associated with the channel contention corresponding to the first MAC frame belongs to the AP, part or all of the STAs in the first STA group feed back UL buffer status information upon receiving a null data physical protocol data unit feedback report polling (NFRP) trigger frame from the AP, and resources used by the part or all of the STAs in the first STA group to transmit UL data within the TXOP are associated with the UL buffer status information fed back by the part or all of the STAs in the first STA group.

7 . The method according to claim 2 , wherein in a case where m≥2, STAs with a same service period or similar service periods belong to different STA groups in the m STA groups.

8 . The method according to claim 1 , wherein the grouping information of the STA is associated with a first field in the first MAC frame.

9 . A station (STA), comprising: a processor and a memory, wherein the memory is configured to store one or more computer programs, and the processor is configured to call and run the one or more computer programs stored in the memory to cause the STA to:
transmit a first medium access control (MAC) frame, wherein the first MAC frame is configured for channel contention, and a channel contention result corresponding to the first MAC frame is associated with grouping information of the STA.

10 . The STA according to claim 9 , wherein the grouping information of the STA comprises at least one of:
information indicating whether the STA belongs to an STA group in m STA groups; or an identifier (ID) of an STA group to which the STA belongs and/or a number of STAs in the STA group to which the STA belongs in a case where the STA belongs to an STA group in m STA groups; wherein the m STA groups are pre-assigned, m is a positive integer, and m=1 or m≥2.

11 . The STA according to claim 9 , wherein that the channel contention result corresponding to the first MAC frame is associated with the grouping information of the STA comprises:
in a case where the STA belongs to a first STA group in m STA groups, and a number of STAs in the first STA group is less than a first threshold, a transmission opportunity (TXOP) associated with the channel contention corresponding to the first MAC frame belongs to the STA; and/or in a case where the STA belongs to a first STA group in m STA groups, and a number of STAs in the first STA group is greater than or equal to a first threshold, a TXOP associated with the channel contention corresponding to the first MAC frame belongs to an access point (AP); and/or in a case where the STA does not belong to any STA group in m STA groups, a TXOP associated with the channel contention corresponding to the first MAC frame belongs to the STA; wherein the m STA groups are pre-assigned, m is a positive integer, and m=1 or m≥2.

12 . The STA according to claim 11 , wherein in a case where the TXOP associated with the channel contention corresponding to the first MAC frame belongs to the AP, part or all of the STAs in the first STA group transmit UL data within the TXOP upon receiving a trigger frame from the AP.

13 . The STA according to claim 11 , wherein in a case where the TXOP associated with the channel contention corresponding to the first MAC frame belongs to the AP, part or all of the STAs in the first STA group transmit UL data and receive downlink (DL) data within the TXOP upon receiving a trigger frame from the AP.

14 . The STA according to claim 11 , wherein in a case where the TXOP associated with the channel contention corresponding to the first MAC frame belongs to the AP, part or all of the STAs in the first STA group feed back UL buffer status information upon receiving a null data physical protocol data unit feedback report polling (NFRP) trigger frame from the AP, and resources used by the part or all of the STAs in the first STA group to transmit UL data within the TXOP are associated with the UL buffer status information fed back by the part or all of the STAs in the first STA group.

15 . The STA according to claim 10 , wherein in a case where m≥2, STAs with a same service period or similar service periods belong to different STA groups in the m STA groups.

16 . The STA according to claim 9 , wherein the grouping information of the STA is associated with a first field in the first MAC frame.

17 . An access point (AP), comprising: a processor and a memory, wherein the memory is configured to store one or more computer programs, and the processor is configured to call and run the one or more computer programs stored in the memory to cause the AP to:
receive a first MAC frame from a station (STA), wherein the first MAC frame is configured for channel contention, a channel contention result corresponding to the first MAC frame is associated with grouping information of the STA, and the STA has uplink (UL) data to be transmitted.

18 . The AP according to claim 17 , wherein the grouping information of the STA comprises at least one of:
information indicating whether the STA belongs to an STA g
