1. A method for transmitting a frame in a wireless communication system, the method comprising:
preparing the frame having a first part for a first type of station (STA) and a second part for a second type of STA; and
transmitting the prepared frame to one or more STAs,
wherein the second part includes a first signaling field (HE-SIG A) and a second signaling field (HE-SIG B),
wherein HE-SIG B includes a user specific control information part for signaling user specific control information for an Orthogonal Frequency Divisional Multiple Access (OFDMA) scheme or a Multi-User Multiple-Input Multiple-Output (MU-MIMO) scheme,
wherein the prepared frame is transmitted in a bandwidth of 80 MHz or 160 MHz,
wherein first signaling information for HE-SIG B transmitted via a first 20 MHz channel and second signaling information for HE-SIG B transmitted via a second 20 MHz channel have resource allocation information for different frequency regions adjacent to each other,
wherein the first signaling information includes resource allocation information for a first and a third frequency regions,
wherein the second signaling information includes resource allocation information for a second and a fourth frequency regions,
wherein the first, the second, the third, and the fourth frequency regions are non-overlapping different frequency regions, and are contiguous frequency regions in a sequence of the first, the second, the third, and the fourth frequency regions,
wherein the first 20 MHz channel and the second 20 MHz channel are within a first 40 MHz channel, and
wherein the first signaling information and the second signaling information transmitted via the first 40 MHz channel are duplicated in a second 40 MHz channel such that the resource allocation information for the first and the third frequency regions and the resource allocation information for the second and the fourth frequency regions are alternately allocated within an 80 MHz channel.
