Abstract: Proposed are a method and an apparatus for transferring information requested by a non-AP STA for P2P transmission to an AP in a wireless LAN system. Specifically, a first receiving STA receives a QoS data frame or a QoS null frame from a transmitting STA. The first receiving STA receives a MU-RTS TXS frame from the transmitting STA. The first receiving STA transmits data to a second receiving STA on the basis of the MU-RTS TXS frame. The QoS data frame or the QoS null frame includes a TXS control frame. The TXS control frame includes first information on a time required for transmission of the data and second information on a bandwidth required for the transmission of the data. The MU-RTS TXS frame includes third information on a time allocated for transmitting the data and fourth information on a bandwidth allocated for transmitting the data.

Abstract: Disclosed are a method and an apparatus for accessing a channel in a wireless LAN system. A method performed by a station (STA) in a wireless LAN system according to an embodiment of the present disclosure may comprise the steps of: receiving information related to a restricted-target wake time (R-TWT) service period (SP) from an access point (AP); and setting at least one R-TWT traffic identifier (TID) for the R-TWT SP. Here, whether to perform a back-off operation for an access category (AC) in the R-TWT SP may be determined on the basis of a mapping relationship between the at least one R-TWT TID and the AC.
