Abstract

One example discloses a first multi-link device (MLD) within a wireless local area network (WLAN), including: a controller configured to receive a multi-link setup request for the first MLD to associate with a second MLD on a first set of PHY-layer links; wherein the controller is configured to transmit a response to the second MLD; and wherein the response associates the first MLD with the second MLD on a second set of PHY-layer links.

Claims (59)

1. A first multi-link device (MLD) within a wireless local area network (WLAN), comprising:

a controller configured to receive a multi-link setup request for the first MLD to associate with a second MLD on a transmitted link within a first set of PHY-layer links;

wherein the controller is configured to transmit a response to the second MLD on a non-transmitted link within a second set of PHY-layer links; and

wherein the response associates the first MLD with the second MLD on the non-transmitted link within the second set of PHY-layer links.

2. The device of claim 1 :

wherein the request is an Association or Reassociation Request frame; and

wherein the response is an Association or Reassociation Response frame.

3. The device of claim 1 :

wherein the first device is an AP-MLD; and

wherein the second device is a non-AP-MLD.

4. The device of claim 1 :

wherein the first set of PHY-layer links overlaps with the second set of PHY-layer links; and

wherein the second MLD considers that link setup is made only on the overlapping PHY-layer links.

5. The device of claim 1 :

wherein the first set of PHY-layer links does not overlap with the second set of PHY-layer links; and

wherein the second MLD considers that link setup is made only on the second set of PHY-layer links.

6. The device of claim 1 :

wherein the first set of PHY-layer links includes only a single link and the second set of PHY-layer links also includes the single link; and

wherein the second MLD considers that link setup is made only on the single link.

7. The device of claim 1 :

wherein the first set of PHY-layer links includes a first link and the second set of PHY-layer links includes a second link that is different from the first link; and

wherein the second MLD considers that link setup is made only on the second link.

8. The device of claim 1 :

wherein the response to the second MLD is a multi-link setup response.

9. The device of claim 8 :

wherein the response includes a basic variant multi-link (ML) element.

10. The device of claim 9 :

wherein the basic variant ML element does not include a Link Info field.

11. The device of claim 9 :

wherein the basic variant ML element does not include a Per-STA profile subelement.

12. The device of claim 9 :

wherein the basic variant ML element includes a common information field.

13. The device of claim 9 :

wherein the basic variant ML element includes an MLD MAC address.

14. The device of claim 9 :

wherein the response includes a capability information field outside of the basic variant ML element.

15. The device of claim 14 :

wherein the capability information field includes a status code field and/or an AID field.

16. The device of claim 1 :

wherein the response to the second MLD is not a multi-link setup response.

17. The device of claim 16 :

wherein the response does not include a basic variant multi-link (ML) element.

18. The device of claim 16 :

wherein the response does not include information on the first MLD's other link capabilities.

19. The device of claim 1 :

wherein the request is from the second MLD.

20. A first multi-link device (MLD) within a wireless local area network (WLAN), comprising:

a controller configured to receive a multi-link setup request for the first MLD to associate with a second MLD on a first set of PHY-layer links;

wherein the controller is configured to transmit a response to the second MLD;

wherein the response associates the first MLD with the second MLD on a second set of PHY-layer links;

wherein the first set of PHY-layer links includes a first link and the second set of PHY-layer links includes a second link that is different from the first link; and

wherein the second MLD considers that link setup is made only on the second link.

21. A first multi-link device (MLD) within a wireless local area network (WLAN), comprising:

a controller configured to receive a multi-link setup request for the first MLD to associate with a second MLD on a first set of PHY-layer links;

wherein the controller is configured to transmit a response to the second MLD;

wherein the response associates the first MLD with the second MLD on a second set of PHY-layer links;

wherein the response to the second MLD is a multi-link setup response;

wherein the response includes a basic variant multi-link (ML) element; and

wherein the response includes a capability information field outside of the basic variant ML element.
