Abstract
Provided is a method and an apparatus of configuring a LTF sequence in a wireless LAN system. In specific, a transmitting apparatus configures a LTF sequence of a second wireless LAN system by using a LTF sequence of a first wireless LAN system. The transmitting apparatus transmits the LTF sequence of the second wireless LAN system via a PPDU including a first field region and a second field region. The LTF sequence of the second wireless LAN system includes a first LTF sequence obtained by up-scaling a frequency index of the LTF sequence of the first wireless LAN system by four times and a second LTF sequence obtained by adding a frequency index which an optimized coefficient is applied. A phase rotation is applied to the LTF sequence of first wireless LAN system as per a first frequency band.
