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).

Abstract: In a wireless local area network (LAN) system, a sharing access point (AP) can determine a Q-matrix related to a first antenna of a first shared AP, a second antenna of the first shared AP, a third antenna of a second shared AP, and a fourth antenna of the second shared AP. The sharing AP can transmit, to the first shared AP, a first value related to the first antenna and a second value related to the second antenna in the Q-matrix. The sharing AP can transmit, to the second shared AP, a third value related to the third antenna and a fourth value related to the fourth antenna in the Q-matrix.
