Abstract: Provided is a method for a first station (STA) transmitting a frame to a second STA in a wireless LAN system. To this end, the first STA generates a wireless frame comprising a first part (L-part) for a first-type STA and a second part (HE-part) for a second-type STA, wherein the first part comprises a legacy short training field (L-STF), a legacy long training field (L-LTF) and a legacy signaling field (L-SIG), and the length of the L-SIG is set so as to indicate that the wireless frame is a frame of different types according to the remainder when the length of the L-SIG is divided by a predetermined natural number.

Abstract: Disclosed is a method of transmitting a synchronization signal from a moving cell base station in a wireless communication system. The present invention includes mapping a moving cell synchronization signal sequence generated on a basis of a sequence assigned for a moving cell to a frequency region and transmitting the mapped moving cell synchronization signal sequence. Moreover, the moving cell synchronization signal sequence may be mapped to the frequency region different from a prescribed frequency region for transmitting a synchronization signal for a user equipment unsupportive of the moving cell.
