US 2026/0313684 A1 · CHANNEL ACCESS IN MULTI-LINK

Abstract

A method for a non-simultaneous transmit and receive (non-STR) device in a wireless local area network (LAN) is provided. The non-STR device may support a multi-link communication related to a first link and a second link. The non-STR device may determine whether to transmit a first physical protocol data unit (PPDU), PPDU, based on a channel access result on the first link and a channel access result on the second link. The non-STR device determines not to transmit the first PPDU through the first link and keeps the back-off counter of the first link at zero (0) when a back-off counter of the first link reaches zero (0) and a back-off counter of the second link does not reach zero (0).

Dependent claims

A method in a wireless local area network (WLAN) system, the method comprising:

performing, by a first station (STA) affiliated with a multi-link device (MLD), channel access,
wherein the first STA operates on a first link that is a part of a non-simultaneous transmit and receive (NSTR) link pair for the MLD, wherein a second STA operates on a second link of the NSTR link pair;
based on a back-off counter related to the first link reaching zero, choosing, by the first STA, to not transmit a physical protocol data unit (PPDU), and keeping, by the first STA, the back-off counter related to the first link at zero;
and
based on the back-off counter related to the first link being zero and the second STA obtaining a transmission opportunity, initiating, by the first STA, transmission on the first link.
