Abstract: In a wireless local area network (WLAN) system, a transmission STA can transmit a PPDU via a 320 MHz channel, and a Medium Access Control (MAC) signal may be generated for the PPDU. The MAC signal may include puncturing pattern information and channel center frequency segment (CCFS) information for a 320 MHz band. The CCFS information may include a first CCFS field related to channel center frequency (CCF) information of a primary 160 MHz channel, and a second CCFS field related to CCF information of a 320 MHz channel.

Abstract: Provided is a method and device for transceiving a frame in a wireless Local Area Network (LAN) system. Particularly, an Access Point (AP) transmits a first frame to a first station (STA) via a first band. The AP receives a second frame from a second STA via a second band while the first frame is being transmitted. The first band and the second band are combined with each other as a multi-band. The multi-band simultaneously supports a Downlink (DL) transmission and a Uplink (UL) transmission. The relationship between the first STA and the second STA is a hidden node. A Physical (PHY) header of the first frame includes channel status information of the second band. A Network Allocation Vector (NAV) of the first STA is set up on the basis of the channel status information.

Abstract: In a wireless local area network system, a sharing access point (AP) may determine a long training field (LTF) subcarrier pattern for each of multiple streams, wherein an LTF symbol is used for at least one stream among a first to a third stream, the number of the LTF symbols is determined on the basis of the number of antennas of a shared AP having the maximum number of antennas among multiple shared APs associated with the sharing AP, and the first to the third stream are assigned different subcarrier patterns. The sharing AP may transmit information associated with the LTF subcarrier pattern.

Abstract: Proposed are a method and a device for transmitting data in a wireless LAN system. Specifically, a transmission device receives configuration information of a multi-band formed by aggregating first to third bands. The transmission device carries out channel sensing on the first to third bands. The transmission device transmits data to a receiving device on the basis of the result of the channel sensing. The first band comprises a first primary channel and a first secondary channel; the second band comprises a second primary channel and a second secondary channel; and the third band comprises a third primary channel and a third secondary channel.

Abstract: In a wireless local area network (WLAN) system, a transmitting multi-link device (MLD) may defer the transmission of a PPDU on a first link, even if a back-off counter of a non-primary link reaches zero, as long as a back-off counter of a primary link does not reach zero. When the transmission of the PPDU is deferred, the back-off counter may be kept at zero.

Abstract: A method and apparatus for communicating in a wireless LAN system are disclosed. The method by which a first station (STA) communicates in a wireless LAN system comprises the steps of: performing, with a second STA, a restricted target wake time (r-TWT) membership setup procedure; and receiving, from the second STA, r-TWT schedule information included in a broadcast TWT element, wherein, on the basis that a specific portion of a first transmission opportunity (TX-OP) in a r-TWT service period (SP) notified by the r-TWT schedule information is not used for downlink (DL) frame transmission corresponding to at least one r-TWT DL traffic identifier (TID) or uplink (UL) frame request corresponding to at least one r-TWT UL TID, the first TXOP may be terminated before the start time of the r-TWT SP.
