Abstract
An operation method of station in wireless local area network is provided. The operation method includes generating a legacy preamble, generating a high efficiency (HE) preamble including at least one HE-signal (HE-SIG) field, a HE-short training field (HE-STF), and at least one HE-long training field (HE-LTF), and generating a HE physical layer convergence procedure protocol data unit (HE-PPDU) including the legacy preamble and the HE preamble. Therefore, performance of WLAN can be enhanced.
