(54)	LINK AVAILABILITY INDICATION FOR NON-PRIMARY LINK OF NSTR (NON-SIMULTANEOUS TRANSMIT AND RECEIVE) LINK PAIR IN NSTR AP MLD (ACCESS POINT MULTI-LINK DEVICE)

(57) A first access point, AP, which is affiliated with a AP multi-link device, MLD, operating on a non-simultaneous-transmission-and-reception, NSTR, link pair comprising a primary link and a non-primary link, generates a beacon frame or probe response frame (710). The first AP then transmits the beacon frame or probe response frame on a link that is not the non-primary link to indicate that a second AP affiliated with the NSTR AP MLD and operating on the non-primary link is unavailable, quiet or disabled (720).
