Classification: CPC H | IPC H

Claim 12:
13. A device used in a wireless local area network (LAN) system, comprising:
a memory; and
a processor operatively coupled to the memory,
wherein the processor is adapted to:
transmit a Management frame including channel center frequency segment (CCFS) information and puncturing information for a 320 MHz Basic Service Set (BSS) bandwidth,
wherein the CCFS information includes a first CCFS field indicating a channel center frequency (CCF) index of a primary 160 MHz channel, and a second CCFS field indicating a CCF index of a 320 MHz BSS bandwidth,
wherein the puncturing information includes bitmap information related to at least one subchannel to be punctured within the 320 MHz BSS bandwidth.and
receive an extremely high throughput (EHT) physical protocol data unit (PPDU), which is generated 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, and
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).
