An operation method of a station in a wireless local area network (WLAN) is disclosed. An operation method of a first station comprises generating a high efficiency (HE) preamble including scheduling information of a plurality of reception stations; and generating a physical layer convergence procedure (PLCP) protocol data unit (PPDU) including a legacy preamble, the HE preamble, and a payload having data units to be transmitted to the plurality of reception stations. Therefore, a performance of WLAN may be enhanced.
