A method for transmitting a radio frame to a plurality of Stations, STAs, in a Wireless Local Area Network, WLAN, system, the method being performed by a wireless apparatus and comprising: generating a frame including a legacy part, L-part, for first type STAs and a high efficiency, HE, part for second type STAs, the first type STAs being legacy STAs in view of the second type STAs, the second type STAs being HE STAs in that they support transmission rates higher than the transmision rates supported by the first type STAs, the HE part including a signaling field and a data field; and transmitting the generated frame to the plurality of STAs within a 80 MHz band, the method being characterized in that: the signaling field of the HE part includes: a first signaling field, HE SIG A field, including control information for frame interpretation, the control information of the HE-SIG A field including bandwidth information, guard interval length information and Basic Service Set, BSS, color information, and a second signaling field, HE SIG B field, including a first block including common control information for the plurality of STAs, and one or more second blocks including user specific control information for individual STAs of the plurality of STAs, wherein the control information of the HE SIG A field in one 20 MHz band is duplicated in the other 20 MHz bands within the 80 MHz band, wherein the HE SIG B field in two 20 MHz bands within a first 40 MHz band among the 80 MHz band has independent control information, and wherein the independent control information of the two 20 MHz bands within the first 40 MHz band is respectively duplicated in two 20 MHz bands within a second 40 MHz band among the 80 MHz band. generating a frame including a legacy part, L-part, for first type STAs and a high efficiency, HE, part for second type STAs, the first type STAs being legacy STAs in view of the second type STAs, the second type STAs being HE STAs in that they support transmission rates higher than the transmision rates supported by the first type STAs, the HE part including a signaling field and a data field; and transmitting the generated frame to the plurality of STAs within a 80 MHz band, the method being characterized in that: the signaling field of the HE part includes: a first signaling field, HE SIG A field, including control information for frame interpretation, the control information of the HE-SIG A field including bandwidth information, guard interval length information and Basic Service Set, BSS, color information, and a second signaling field, HE SIG B field, including a first block including common control information for the plurality of STAs, and one or more second blocks including user specific control information for individual STAs of the plurality of STAs, wherein the control information of the HE SIG A field in one 20 MHz band is duplicated in the other 20 MHz bands within the 80 MHz band, wherein the HE SIG B field in two 20 MHz bands within a first 40 MHz band among the 80 MHz band has independent control information, and wherein the independent control information of the two 20 MHz bands within the first 40 MHz band is respectively duplicated in two 20 MHz bands within a second 40 MHz band among the 80 MHz band. the signaling field of the HE part includes: a first signaling field, HE SIG A field, including control information for frame interpretation, the control information of the HE-SIG A field including bandwidth information, guard interval length information and Basic Service Set, BSS, color information, and a second signaling field, HE SIG B field, including a first block including common control information for the plurality of STAs, and one or more second blocks including user specific control information for individual STAs of the plurality of STAs, a first signaling field, HE SIG A field, including control information for frame interpretation, the control information of the HE-SIG A field including bandwidth information, guard interval length information and Basic Service Set, BSS, color information, and a second signaling field, HE SIG B field, including a first block including common control information for the plurality of STAs, and one or more second blocks including user specific control information for individual STAs of the plurality of STAs, wherein the control information of the HE SIG A field in one 20 MHz band is duplicated in the other 20 MHz bands within the 80 MHz band, wherein the HE SIG B field in two 20 MHz bands within a first 40 MHz band among the 80 MHz band has independent control information, and wherein the independent control information of the two 20 MHz bands within the first 40 MHz band is respectively duplicated in two 20 MHz bands within a second 40 MHz band among the 80 MHz band.
