A method for transmitting a frame by an AP includes generating and transmitting a radio frame including a signaling field and a data field. The signaling field includes a SIG A field including first common control information for the plurality of STAs, and a SIG B field including specific control information for each of the plurality of STAs. The second signaling field includes a common field including second common control information for the plurality of STAs, and a specific field following the common field, including the specific control information for each of the plurality of STAs, and the specific field of the second signaling field transmitted in a specific 20-MHz band includes resource allocation information for one or more first-band STAs to which resources are allocated in the first band, and resource allocation information for one or more second-band STAs to which resources are allocated in another 20-MHz band. |
