Abstract

A wireless communication method, a station device, an access point (AP) device are provided. The wireless communication method includes: an AP transmits first information, the first information being used for sharing some or all of the time domain resources of a TXOP obtained by the AP to multiple STAs. The first information is used for indicating at least one of: address information of the multiple STAs, time duration information of time domain resources corresponding to the multiple STAs, start time domain positions of the time domain resources respectively corresponding to the multiple STAs, and the time domain resources respectively corresponding to the multiple STAs.

Claims (32)

1 . A method for wireless communication, comprising:

determining, by an Access Point (AP), that part or all of time domain resources of an acquired transmission opportunity (TXOP) are to be shared to a first station (STA);

transmitting, by the AP, a first trigger frame to the first STA,

wherein the first trigger frame comprises a user information list field and the user information list field comprises a User Info field, wherein the User Info field comprises an Association Identifier AID12 subfield, which occupies bits B0 to B11 of the User Info field, and a resource unit allocation subfield, which occupies bits B12 to B19 of the User Info field,

wherein the User info field further comprises a duration allocation subfield, following the resource unit allocation subfield, which occupies bits B20 to B(20+M−1) of the User Info field, wherein the duration allocation subfield indicates time duration information allocated to the first STA and M is a positive integer smaller than 20.

2 . The method of claim 1 , wherein the duration allocation subfield is redefined from B20 to B(20+M−1) bits of 20 reserved bits which occupy B20 to B39 of the User Info field, wherein the User Info field comprises the AID12 subfield, the resource unit allocation subfield and 20 reserved bits.

3 . The method of claim 1 , wherein the M bits indicate 2 M time units, the time duration allocated to the first STA is obtained according to the 2 M time units.

4 . The method of claim 1 , wherein the duration allocation subfield is followed by reserved bits starting from B(20+M).

5 . The method of claim 1 , wherein the first STA is a non-AP STA.

6 . The method of claim 1 , wherein the first trigger frame is a Multiple Users Request-To-Transmit Transmission Opportunity Sharing Trigger Frame (MU-RTS TXS TF).

7 . The method of claim 1 , wherein the method further comprises:

receiving, by the AP, third information transmitted by the first STA, wherein the third information is used to instruct the first STA to release time domain resources shared to the first STA.

8 . A method for wireless communication, comprising:

receiving, by a first station (STA), a first trigger frame transmitted by an Access Point (AP), wherein the first STA is a STA to be shared part or all of time domain resources of a transmission opportunity (TXOP) acquired by the AP,

wherein the user info field further comprises a duration allocation subfield, following the resource unit allocation subfield, which occupies bits B20 to B(20+M−1) of the User Info field, wherein the duration allocation subfield indicates time duration information allocated to the first STA and M is a positive integer smaller than 20.

9 . The method of claim 8 , wherein the duration allocation subfield is redefined from B20 to B(20+M−1) bits of 20 reserved bits which occupy B20 to B39 of the User Info field, wherein the User Info field comprises the AID12 subfield, the resource unit allocation subfield and 20 reserved bits.

10 . The method of claim 8 , wherein the M bits indicate 2 M time units, the time duration allocated to the first STA is obtained according to the 2 M time units.

11 . The method of claim 8 , wherein the duration allocation subfield is followed by reserved bits starting from B(20+M).

12 . The method of claim 8 , wherein the first trigger frame is a Multiple Users Request-To-Transmit Transmission Opportunity Sharing Trigger Frame (MU-RTS TXS TF).

13 . The method of claim 8 , wherein the first STA is a non-AP STA.

14 . A station device, wherein the station device is a first station (STA), the station device comprises a processor and a memory for storing a computer program, and the processor is configured to call and run the computer program stored in the memory to perform:

receiving a first trigger frame transmitted by an Access Point (AP), wherein the first STA is a STA to be shared part or all of time domain resources of a transmission opportunity (TXOP) acquired by the AP,

15 . The station device of claim 14 , wherein the duration allocation subfield is redefined from B20 to B(20+M−1) bits of 20 reserved bits which occupy B20 to B39 of the User Info field, wherein the User Info field comprises the AID12 subfield, the resource unit allocation subfield and 20 reserved bits.

16 . The station device of claim 14 , wherein the M bits indicate 2 M time units, the time duration allocated to the first STA is obtained according to the 2 M time units.

17 . The station device of claim 14 , wherein the duration allocation subfield is followed by reserved bits starting from B(20+M).

18 . The station device of claim 14 , wherein the first trigger frame is a Multiple Users Request-To-Transmit Transmission Opportunity Sharing Trigger Frame (MU-RTS TXS TF).

19 . The station device of claim 14 , wherein the first STA is a non-AP STA.

20 . The station device of claim 14 , wherein the processor is further configured to call and run the computer program stored in the memory to perform:

transmitting third information to the AP, wherein the third information is used to instruct the first STA to release time domain resources shared to the first STA.
