Abstract: A method and apparatus for transmitting frames having a long training field (LTF) for a second type of station (STA) in a wireless communication system are provided. For this, STA prepares a frame having a first part for a first type of STA and a second part for the second type of STA; wherein the second part includes multiple LTFs, when the frame is used for MU (Multiple User) transmission scheme or OFDMA (Orthogonal Frequency Divisional Multiple Access) scheme. In case a first LTF having a first number of symbols length and a second LTF having a second number of symbols length, which is greater than the first number of symbols length, are used for the multiple LTFs, the first LTF is extended such that the first LTF and the second LTF have a same number of symbols length. The STA transmits the prepared frame to one or more STAs.

Abstract: A method and an apparatus for transmitting a wakeup packet in a wireless LAN system are proposed. Particularly, a transmission device configures a wakeup packet and transmits the wakeup packet to a receiving device. The wakeup packet includes a sequence configured with first information and second information by applying an OOK method. The first information and the second information are configured with an on-signal or an off-signal. The on-signal is transmitted through a first symbol, which is generated by applying a first sequence to K consecutive subcarriers in the 20 MHz band and performing 64-point IFFT. The off-signal is transmitted through a second symbol, which is generated by applying a second sequence to K consecutive subcarriers in the 20 MHz band and performing 64-point IFNT. The first information and the second information are transmitted through a third symbol in which the first symbol or the second symbol is repeated.

Abstract: It is proposed an example for mapping between a signal field and a data field used in a wireless local area network (LAN) system supporting a plurality of resource units (RUs). If a second channel (e.g., a 20 MHz band) is nullified and thus a physical layer protocol data unit (PPDU) is not transmitted, a signal field transmitted through a first channel may include allocation information regarding all data channels, and a signal field transmitted through the first channel is preferably duplicated on a third channel. In this case, a signal field transmitted through a fourth channel may include only allocation information for a data field corresponding to the fourth channel.
