Abstract: A method and apparatus for transmitting frames having a signaling field (SIG) for a second type of station (STA) in a wireless communication system are provided. For this, STA prepares a frame having a first part for a first type of STA and a second part for the second type of STA. Here, the second part includes a first signaling field (HE-SIG A) for common control information and a second signaling field (HE-SIG B) for signaling information comprising user specific control information. Regarding the second signaling field, independent signaling information for the second signaling field (HE-SIG B) is to be transmitted for each 20 MHz bandwidth within a first 40 MHz bandwidth. And the signaling information of the first 40 MHz bandwidth is duplicated in a second 40 MHz bandwidth, when the frame is to be transmitted in a bandwidth equals to or greater than 80 MHz. STA transmits this prepared frame to one or more STAs.
