The present invention relates to a new physical layer protocol data unit (PPDU) format in a wireless local area network (WLAN), and transmission and reception method and apparatus using the same. According to one embodiment of the present invention, a method for transmitting a PPDU frame to a reception apparatus by a transmission apparatus in a WLAN may be provided. The method may comprise the following steps of: generating a legacy preamble; generating a high efficiency (HE)-preamble; and transmitting a PPDU frame including a first region including the legacy preamble and a first field and a second region the HE-preamble to the reception apparatus. The first field may have a variable length, and the HE-preamble may include a high efficiency-short training field (HE-STF) subsequent to the first field. |
