Abstract: In a wireless local area network system, an access point (AP) multi-link device (MLD) may receive, from a non-simultaneous transmit and receive (NSTR) station MLD (NSTR STA MLD), STR information related to transmit power information for the NSTR STA MLD to operate in STR. The NSTR STA MLD includes a first STA and a second STA, the first STA operates in a first link, the second STA operates in a second link, and the first and second links have NSTR relationship. The AP MLD may receive, from the NSTR STA MLD, a reference signal to calculate a path loss between the NSTR STA MLD and the AP MLD. The reference signal may include a transmit power value of the reference signal. The AP MLD may determine whether the NSTR STA MLD is capable of operating in STR based on the STR information and the path loss value.

Abstract: The present specification proposes an example in which different types of Physical Protocol Data Units (PPDUs) are aggregated. Different types of PPDUs may be included in one aggregated PPDU (A-PPDU). Different types of PPDUs may be composed of the same version of the PPDUs or may be composed of different versions of the PPDUs. Different types of PPDUs may be allocated to a primary channel or a non-primary channel. Different types of PPDUs may be allocated to various frequency bands. Broadband communication can be supported compared to the related art through one A-PPDU including different types. In addition, through the additional technical features proposed in the present specification, efficient communication for receiving STAs of different standards is possible.

Abstract: A transmitting station (STA) of a wireless local area network (WLAN) system may determine an access category (AC) of a first class traffic. For example, the AC of the first class traffic may be determined as a first AC at a first likelihood. For example, the AC of the first class traffic may be determined as a second AC at a second likelihood. For example, a sum of the first likelihood and the second likelihood may be equal to 1. The transmitting STA may transmit the first class traffic based on the determined AC of the first class traffic. The class for the first traffic may be determined based on at least one of a latency requirement of the first traffic, and a buffer status of the transmitting STA.

Abstract: Provided is a method for providing information related to at least one channel supported in a wireless local area network (WLAN) system. For example, an extreme high throughput (EHT) operation element may include information related to at least one channel in a first band supporting an EHT standard. A very high throughput (VHT) operation element may include information related to at least one channel in a second band supporting a VHT standard. A high throughput (HT) operation element may include information related to at least one channel in a third band supporting an HT standard. The EHT operation element may include information for a channel number related to at least one channel in the first band and information related to a primary channel in the first band.
