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.

Operation method of station in wireless local area network

Disclosed are multi-user transmission methods in a wireless local access network (WLAN). An operation method performed in a first station may comprise generating a physical layer convergence procedure (PLCP) protocol data unit (PPDU) including a legacy preamble, a high efficiency (HE) preamble, and a payload; and transmitting the PPDU. Also, the HE preamble may include a HE signal A (HE-SIG-A) field, a HE signal B (HE-SIG-B) field, a HE short training field (HE-STF), and a HE long training field (HE-LTF), and the HE-SIG-A field may include information indicating the number of symbols of the HE-SIG-B field. Accordingly, a performance of the WLAN may be enhanced.

Transmission method for multi user in wireless local area network

An interleaving method by a transmitting device is provided. The transmitting device divides a bandwidth into a plurality of bands, and divides an interleaver matrix into a plurality of matrices corresponding to the plurality of bands respectively in a predetermined direction. Next, the transmitting device arranges data of a user assigned to a corresponding band among the plurality of bands in each matrix of the plurality of matrices.
