Abstract
The invention relates in one of its aspects to a method of communication in a wireless network comprising an access point multi-link device, AP MLD, and the wireless network further comprising a first and a second station multi-link devices, STA MLDs. The method comprising: establishing a first link between a station of the first STA MLD and an Access Point of the AP MLD; establishing a second link between a station of the second STA MLD and an Access Point of the AP MLD; establishing a third direct link between station of the first STA MLD and a station of the second STA MLD; and transferring data between the first and the second STA MLDs through the third link.

A method of communication in a wireless network comprising an access point multi-link device, AP MLD, and the wireless network further comprising first and second station multi-link devices, STA MLDs, the method comprising:
- establishing a first link between a station of the first STA MLD and an Access Point of the AP MLD;
- establishing a second link between a station of the second STA MLD and an Access Point of the AP MLD;
- establishing a third direct link between a station of the first STA MLD and a station of the second STA MLD;
- and
- transferring data traffic initially conveyed between the first and the second STA MLDs over the first and second links, to the third direct link
- wherein, for performing the transferring,
- the first STA MLD is configured to, in response to a link transition message that the AP MLD transmits over the first link with the first STA MLD, unmap a traffic stream identifier, TSID, for identifying the data traffic, in a unified upper-MAC, UMAC, of the first STA MLD, from the first link, and map the TSID to the third direct link,
- the second STA MLD is configured to, in response to a link transition message that the AP MLD transmits over the second link with the second STA MLD, unmap the TSID, in UMAC of the second STA MLD, from the second link, and map the TSID to the third direct link, and
- wherein the link transition message includes at least the TSID and information for identifying the third direct link.
A method of communication in a wireless network comprising an access point multi-link device, AP MLD, and the wireless network further comprising first and second station multi-link devices, STA MLDs, the method comprising, for the AP MLD:
- establishing a first link between a station of the first STA MLD and an Access Point of the AP MLD;
- establishing a second link between a station of the second STA MLD and an Access Point of the AP MLD;
- and
- establishing a third direct link between the first STA MLD and the second STA MLD, and for transferring data traffic initially conveyed over the first and second links to the third direct link, transmitting a link transition message that includes a TSID for identifying the data traffic and information for identifying the third direct link to the first STA MLD and the second STA MLD over the first link or the second link,
- wherein the first STA MLD is configured to, in response to the message, unmap the TSID, in UMAC of the first STA MLD, from the first link, and map the TSID to the third direct link, and
- wherein the second STA MLD is configured to, in response to the message, unmap the TSID, in UMAC of the second STA MLD, from the second link, and map the TSID to the third direct link.
A method of communication in a wireless network comprising an access point multi-link device, AP MLD, and the wireless network further comprising first and second station multi-link devices, STA MLDs, the method comprising, for each STA MLD:
- establishing a first link between a station of the STA MLD and an Access Point of the AP MLD;
- and
- establishing a third direct link between a station of the first STA MLD and a station of the second STA MLD;
- wherein, for transferring data traffic initially conveyed over the first link established with the AP MLD to the third direct link, the STA MLD is configured to receive, from the AP MLD, a link transition message that includes a TSID for identifying the data traffic and information for identifying the third direct link, and
- wherein, in response to the message, the TSID, in UMAC of the STA MLD, is unmapped from the first link, and mapped to the third direct link.
