Abstract: Disclosed are methods and apparatuses for transmitting and receiving a frame in a WLAN. A method for transmitting a frame, performed in a first station, may comprise receiving a first PPDU; determining whether a BSS of the first PPDU is a BSS to which the first station belongs or a BSS to which the first station does not belong; when the BSS of the first PPDU is the BSS to which the first station does not belong and a received signal strength of the first PPDU is higher than a first threshold, setting a virtual carrier sensing by using information included in a preamble of the first PPDU. Therefore, performance of the WLAN can be enhanced.
