US 12,587,905 B2 · Method and apparatus for mobile ap backhaul link setup and operation

Abstract

Methods and apparatuses for facilitating the use of stations (STAs) of a multi-link device (MLD) to set up and operate backhaul links to serve a Mobile access point (AP) within the same MLD in a wireless local area network. The apparatuses include an MLD comprising APs forming a Mobile AP MLD, backhaul STAs, and a processor operably coupled to the APs and the backhaul STAs. The processor is configured to instruct at least one of the APs to set up an access link with a corresponding STA of a non-AP MLD, and to instruct at least one of the backhaul STAs to set up a backhaul link with a corresponding AP of an AP MLD to carry traffic of the non-AP MLD that flows through the Mobile AP MLD over the access link.

Dependent claims

A multi-link device (MLD) comprising:

access points (APs) forming a Mobile AP MLD, each of the APs configured as an AP station (STA) and comprising a transceiver, the APs configured to form a primary link and a non-primary link with corresponding stations (STAs) configured as non-AP STAs of a non-AP MLD;
backhaul STAs, each of the backhaul STAs configured as a non-AP STA and comprising a transceiver;
and
a processor operably coupled to the APs and the backhaul STAs, the processor configured to:
instruct at least one of the APs to set up an access link with its corresponding STA;
and
instruct at least one of the backhaul STAs to set up a backhaul link with a corresponding AP configured as an AP STA of an AP MLD to carry traffic of the non-AP MLD that flows through the Mobile AP MLD over the access link.
