A method for wireless communication, applied to a non-access point multi-link device (Non-AP MLD), wherein the Non-AP MLD at least comprises a first non-access point station (Non-AP STA) affiliated to the Non-AP MLD and a second Non-AP STA affiliated to the Non-AP MLD, the first Non-AP STA operates on a primary link and obtains a first transmission opportunity (TXOP) on the primary link, the second Non-AP STA operates on a non-primary link and obtains a second TXOP on the non-primary link, and the method comprises:
- simultaneously transmitting, by the first Non-AP STA affiliated to the Non-AP MLD and the second Non-AP STA affiliated to the Non-AP MLD, at least one physical layer protocol data unit (PPDU) in the first TXOP and the second TXOP respectively,
- wherein the first TXOP and the second TXOP meet:
- end times of PPDUs transmitted simultaneously on the primary link and the non-primary link meet an alignment requirement;
- wherein the end times of PPDUs transmitted simultaneously on the primary link and the non-primary link meet an alignment requirement comprises:
- the end times of the PPDUs transmitted simultaneously on the primary link and the non-primary link are different and a difference between the end times of the PPDUs transmitted simultaneously on the primary link and the non-primary link is less than or equal to 8 microseconds,
- wherein the method further comprises:
- in a case that the second Non-AP STA detects that the first Non-AP STA fails to send PPDUs on the primary link, the first Non-AP STA does not restart a backoff process on the primary link, and the first Non-AP STA executes a priority interframe space (PIFS) recovery mechanism, stopping, by the second Non-AP STA, transmitting to-be-transmitted PPDUs on the non-primary link, and maintaining, by the second Non-AP STA, a backoff counter thereof to be zero until the first Non-AP STA starts transmitting PPDUs after executing the PIFS recovery mechanism.
A device for wireless communication, used as a non-access point multi-link device (Non-AP MLD), wherein the Non-AP MLD at least comprises a first non-access point station (Non-AP STA) affiliated to the Non-AP MLD and a second Non-AP STA affiliated to the Non-AP MLD, the first Non-AP STA operates on a primary link and obtains a first transmission opportunity (TXOP) on the primary link, the second Non-AP STA operates on a non-primary link and obtains a second TXOP on the non-primary link, wherein the device comprises:
- a memory, configured to store a computer program;
- and
- a processor, configured to call and run the computer program stored in the memory, to execute a method for wireless communication comprising:
- simultaneously transmitting, by the first Non-AP STA affiliated to the Non-AP MLD and the second Non-AP STA affiliated to the Non-AP MLD, at least one physical layer protocol data unit (PPDU) in the first TXOP and the second TXOP respectively,
- wherein the first TXOP and the second TXOP meet:
- end times of PPDUs transmitted simultaneously on the primary link and the non-primary link meet an alignment requirement;
- wherein the end times of PPDUs transmitted simultaneously on the primary link and the non-primary link meet an alignment requirement comprises:
- the end times of the PPDUs transmitted simultaneously on the primary link and the non-primary link are different and a difference between the end times of the PPDUs transmitted simultaneously on the primary link and the non-primary link is less than or equal to 8 microseconds,
- wherein the method further comprises:
- in a case that the second Non-AP STA detects that the first Non-AP STA fails to send PPDUs on the primary link, the first Non-AP STA does not restart a backoff process on the primary link, and the first Non-AP STA executes a priority interframe space (PIFS) recovery mechanism, stopping, by the second Non-AP STA, transmitting to-be-transmitted PPDUs on the non-primary link, and maintaining, by the second Non-AP STA, a backoff counter thereof to be zero until the first Non-AP STA starts transmitting PPDUs after executing the PIFS recovery mechanism.
