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: Proposed are a method and device for receiving a PPDU in a wireless LAN system. Specifically, a reception STA receives the PPDU from a transmission STA through a wide band, and decodes the PPDU. The PPDU includes a legacy preamble, and first and second signal fields. The legacy preamble and the first and second signal fields are generated on the basis of a first phase rotation value. When the wide band is the 320 MHz band, the first phase rotation value is [1 −1 −1 −1 1 −1 −1 −1 1 −1 −1 −1 −1 1 1 1].
