US 2019/0158385 A1 · LINK AGGREGATION WITH FLOATING PRIMARY LINK

Abstract

This disclosure provides systems, methods, and apparatuses for dynamically changing a primary communication link on which wireless devices contend for access to a shared wireless medium. An access point (AP) may monitor the channel conditions on a primary link and one or more secondary links of a multi-link environment, and may signal a change in the primary link (such as to one of the secondary links) when one or more conditions are satisfied. The primary and secondary links may be assigned on a per-client basis. Thus, the primary or secondary links of a particular STA may be different than those of other STAs associated with the same AP. In some aspects, each STA may monitor the channel conditions on its own primary and secondary links, and may signal a change in its primary link (such as to one of its secondary links) when one or more conditions are met.

Dependent claims

A method for wireless communication, comprising:

establishing a first primary communication link with a first wireless station (STA), the first primary communication link being associated with one or more first wireless channels, access to the first primary communication link being based on contention with the first STA;
establishing a second primary communication link with a second STA, the second primary communication link being associated with one or more second wireless channels, access to the second primary communication link being based on contention with the second STA;
and
selectively accessing a secondary communication link with at least one of the first STA or the second STA based at least in part on having access to the first primary communication link or the second primary communication link, respectively.

1 more element

A wireless communication device comprising:

one or more processors;
and
a memory storing instructions that, when executed by the one or more processors, cause the wireless communication device to:
establish a first primary communication link with a first wireless station (STA), the first primary communication link being associated with one or more first wireless channels, access to the first primary communication link being based on contention;
establish a second primary communication link with a second STA, the second primary communication link being associated with one or more second wireless channels, access to the second primary communication link being based on contention;
and
selectively access a secondary communication link with at least one of the first STA or the second STA based at least in part on having access to the first primary communication link or the second primary communication link, respectively.
