Abstract

Claims (52)

1. A multi-link communication method, comprising:

wherein the QTP response frame is sent over a link of the multiple links, or the QTP response frame is sent over two links of the multiple links,

wherein a time offset of QTP supported by the STA, a time offset of QTP supported by the AP, an identifier of a link under which the STA supports QTP in the multi-link communication, and an identifier of a link under which the AP supports QTP in the multi-link communication are link parameters of at least one link for QTP among the multiple links, respectively.

2. The method of claim 1 , further comprising:

receiving, by the AP and via at least one link among the multiple links to the STA, a QTP request frame from the STA, wherein the QTP request frame comprises at least one of following parameters: an identification of at least one link for QTP under which the STA supports QTP among the multiple links, or a link parameter of at least one link for QTP under which the STA supports QTP among the multiple links;

wherein the QTP request frame is received over a link of the multiple links, or the QTP request frame is received overt wo links of the multiple links.

3. The method of claim 2 , wherein the at least one link for receiving the QTP request frame is the same or different from the at least one link for sending the QTP response frame.

4. The method of claim 2 , wherein

the link parameter of the QTP request frame comprises at least a QTP time offset parameter corresponding to a link supporting QTP.

5. The method of claim 4 , wherein

time offset values of different links are time offset values relative to a same time reference point; or

a time offset value of one link is a time offset value relative to a time offset value of another link.

6. The method of claim 2 , wherein

the link parameter of the QTP response frame comprises at least a QTP time offset parameter corresponding to a link supporting QTP.

7. The method of claim 2 , further comprising:

determining, by the AP, a link parameter to be included in the QTP response frame based on a parameter of a Basic Service Set (BSS) of the at least one link supporting QTP and a parameter of a service specific identifier (SSD) of at least one link for QTP under which the STA supports QTP among the multiple links in the QTP request frame.

8. The method of claim 1 , further comprising:

receiving, by the AP, an initial association request from the STA, wherein the initial association request comprises multi-link capability information of the STA;

sending, by the AP, an initial association response to the STA, wherein the initial association response comprises multi-link capability information of the AP; and

establishing, by the AP, a multi-link communication based on the multi-link capability information of the STA and the multi-link capability information of the AP.

9. The method of claim 8 , wherein the multi-link capability information comprises:

support for simultaneous transmissions and receptions of the multi-link communication;

support for simultaneous transmissions or receptions of the multi-link communication; and

support for transmission and reception of a single link.

10. A multi-link communication method, comprising:

receiving, by a station (STA) and via at least one link among multiple links to a wireless access point (AP), a Quiet Time Period (QTP) response frame from the AP, wherein the QTP response frame comprises at least a link parameter of at least one link for QTP among the multiple links, and the at least one link for QTP is a link under which the AP supports QTP;

wherein the QTP response frame is received over a link of the multiple links, or the QTP response frame is received over two links of the multiple links,

wherein a time offset of QTP supported by the STA, a time offset of QTP supported by the AP, an identifier of a link under which the STA supports QTP in the multi-link communication, and an identifier of a link under which the AP supports QTP in the multi-link communication are link parameters of at least one link for QTP among the multiple links, respectively.

11. The method of claim 10 , further comprising:

sending, by the STA and via at least one link among the multiple links, a QTP request frame to the AP, wherein the QTP request frame comprises at least one of following parameters: an identification of at least one link for QTP under which the STA supports QTP among the multiple links or a link parameter of at least one link for QTP under which the STA supports QTP among the multiple links;

wherein the QTP request frame is sent over a link of the multiple links, or the QTP request frame is sent over two links of the multiple links.

12. The method of claim 11 , wherein the at least one link for sending the QTP request frame is the same or different from the at least one link for receiving the QTP response frame.

13. The method of claim 11 , wherein

the link parameter of the QTP request frame comprises at least a QTP time offset parameter corresponding to a link supporting QTP.

14. The method of claim 13 , wherein

time offset values of different links are time offset values relative to a same time reference point; or
