1. A method in a wireless Local Area Network, the method performed by a station (STA) and comprising:
configuring a physical protocol data unit (PPDU) for at least one user,
wherein the PPDU includes a first control signal field for interpreting the PPDU and a second control signal field including additional control information for the PPDU,
wherein the second control signal field is transmitted through a plurality of content channels including a first content channel and a second content channel, wherein the plurality of content channels are allocated to different frequency bands,
wherein the second control signal field further includes a common field comprising at least one encoding block, and a user specific field comprising at least one encoding block,
wherein the common field includes overflowed information from the first control signal field and at least one resource unit (RU) allocation subfield,
wherein a number of encoding blocks included in the common field transmitted through one content channel is set to two for a bandwidth of the PPDU,
wherein a first encoding block of the two encoding blocks includes the overflowed information, two RU allocation subfields, a 4-bit cyclic redundancy code (CRC) field, and a 6-bit Tail field,
wherein a second encoding block of the two encoding blocks includes two RU allocation subfields, a 4-bit CRC field, and a 6-bit Tail field, and
wherein each of the two RU allocation subfields has a length of 9 bits,
wherein the first content channel transmitted on a first frequency band comprises a first common field including the overflowed information and RU allocation subfields related to first tone ranges,
wherein the second content channel transmitted on a second frequency band comprises a second common field including the overflowed information and RU allocation subfields related to second tone ranges,
wherein the first content channel is duplicated on a third frequency band,
wherein the second content channel is duplicated on a fourth frequency band,
wherein the first to fourth frequency bands are sequentially allocated within an 80 MHz frequency subblock,
wherein the first tone ranges comprise tone ranges of {−500:−259} and {12:253}, and the second tone ranges comprise tone ranges of {−253:−12} and {259:500}; and
transmitting the PPDU.
