A method for an access point, AP, to transmit a frame to a plurality of stations, STAs, in a wireless local area network, WLAN, system, the method comprising: generating, at the AP, the frame including a signaling field and a data field, the signaling field including a first signaling field, SIG A field, including common control information of the plurality of STAs and a second signaling field, SIG B field, including user specific control information of each of the plurality of STAs, and the second signaling field further including data transmission resource allocation information of each of the plurality of STAs; and transmitting, by the AP, the generated frame to the plurality of STAs, wherein, a first one of the data transmission resource allocation information transmitted through a first 20 MHz band is independently configured from a second one of the data transmission resource allocation information transmitted through a second 20 MHz band, wherein the first one of the data transmission resource allocation information and the second one of the data transmission resource allocation information are for data transmitted on different data transmission resource regions, wherein the first 20 MHz band and the second 20 MHz band are two contiguous 20 MHz bands, wherein the second signaling field transmitted through a specific 20 MHz band includes data transmission resource allocation information for data transmitted through the specific 20 MHz band, and wherein the second signaling field transmitted through the specific 20 MHz band further includes data transmission resource allocation information for data transmitted through another 20 MHz band which is non-contiguous to the specific 20-MHz band. generating, at the AP, the frame including a signaling field and a data field, the signaling field including a first signaling field, SIG A field, including common control information of the plurality of STAs and a second signaling field, SIG B field, including user specific control information of each of the plurality of STAs, and the second signaling field further including data transmission resource allocation information of each of the plurality of STAs; and transmitting, by the AP, the generated frame to the plurality of STAs, wherein, a first one of the data transmission resource allocation information transmitted through a first 20 MHz band is independently configured from a second one of the data transmission resource allocation information transmitted through a second 20 MHz band, wherein the first one of the data transmission resource allocation information and the second one of the data transmission resource allocation information are for data transmitted on different data transmission resource regions, wherein the first 20 MHz band and the second 20 MHz band are two contiguous 20 MHz bands, wherein the second signaling field transmitted through a specific 20 MHz band includes data transmission resource allocation information for data transmitted through the specific 20 MHz band, and wherein the second signaling field transmitted through the specific 20 MHz band further includes data transmission resource allocation information for data transmitted through another 20 MHz band which is non-contiguous to the specific 20-MHz band.
