1. A method in a wireless local area network (LAN) system, the method comprising:
obtaining, by a station (STA), at least one parameter from an information field which includes a first sub-field, a second sub-field, and a third sub-field,
wherein the information field is included in a management frame,
wherein the first sub-field indicates a channel center frequency (CCF) index of a primary 160 MHz channel, and the second sub-field indicates a CCF index of a 320 MHz channel,
wherein the third sub-field includes bitmap information related to at least one punctured subchannel within a Basic Service Set (BSS) bandwidth; and
transmitting, by the STA, an extremely high throughput (EHT) physical protocol data unit (PPDU) based on the management frame,
wherein the EHT PPDU includes a legacy signal (L-SIG) field, a repeated L-SIG field (RL-SIG) which is a repeat of the L-SIG field, and a control signal field,
wherein the L-SIG field includes a length field which is set to a value satisfying a condition that a remainder is zero when the length field is divided by three,
wherein the RL-SIG field is contiguous to the L-SIG field,
wherein the control signal field carries control information to interpret the EHT PPDU and is contiguous to the RL-SIG field,
wherein the control signal field includes first information related to an identifier of a BSS, second information related to a transmission opportunity (TXOP), third information related to a bandwidth of the EHT PPDU, and fourth information indicating whether the EHT PPDU is transmitted in uplink (UL) or downlink (DL).
