1. A method of communicating, by a first device, with at least one second device in a wireless local area network (WLAN) system, the method comprising:
allocating at least one resource unit (RU) within a bandwidth to a second device;
generating at least one subfield defining the at least one RU; and
transmitting a physical protocol layer data unit (PPDU) comprising the at least one subfield to the at least one second device,
wherein the generating at least one subfield comprises setting at least seven bits associated with the at least one RU and setting at least two bits as a value defining a subband that includes the at least one RU when the bandwidth is 320MHz and the subband is 80MHz,
wherein the allocating the at least one RU comprises allocating a multi-RU to the second device,
wherein the multi-RU comprises at least two single RUs among a plurality of single RUs sequentially arrangeable within the bandwidth,
wherein the allocating of the at least one RU comprises, when the bandwidth is 80 MHz in which first to fourth 242-tone RUs or first to second 484-tone RUs are sequentially arrangeable, allocating a multi-RU comprising a 484-tone RU and a 242-tone RU to the second device, and wherein the multi-RU is one of four multi-RUs which include the first through fourth 242-tone RUs, respectively.
 
14. A method of communicating, by a first device, with at least one second device in a wireless local area network (WLAN) system, the method comprising:
allocating at least one resource unit (RU) within a bandwidth to a second device;
generating at least one subfield defining the at least one RU; and
transmitting a physical protocol layer data unit (PPDU) comprising the at least one subfield to the at least one second device,
wherein the generating at least one subfield comprises setting at least seven bits associated with the at least one RU and setting at least two bits as a value defining a subband that includes the at least one RU when the bandwidth is 320MHz and the subband is 80MHz,
wherein the allocating the at least one RU comprises allocating a multi-RU to the second device,
wherein the multi-RU comprises at least two single RUs among a plurality of single RUs sequentially arrangeable within the bandwidth,
wherein the allocating of the at least one RU comprises, when the bandwidth is 160 MHz in which first to fourth 484-tone RUs or first and second 996-tone RUs are sequentially arrangeable, allocating a multi-RU comprising a 996-tone RU and a 484-tone RU to the second device, and wherein the multi-RU is one of four multi-RUs which include the first to fourth 484-tone RUs, respectively.
 
16. A method of communicating, by a first device, with at least one second device in a wireless local area network (WLAN) system, the method comprising:
allocating at least one resource unit (RU) within a bandwidth to a second device;
generating at least one subfield defining the at least one RU; and
transmitting a physical protocol layer data unit (PPDU) comprising the at least one subfield to the at least one second device,
wherein the generating at least one subfield comprises setting at least seven bits associated with the at least one RU and setting at least two bits as a value defining a subband that includes the at least one RU when the bandwidth is 320MHz and the subband is 80MHz,
wherein the allocating the at least one RU comprises allocating a multi-RU to the second device,
wherein the multi-RU comprises at least two single RUs among a plurality of single RUs sequentially arrangeable within the bandwidth,
wherein the allocating of the at least one RU comprises, when the bandwidth is 160 MHz in which first to eighth 242-tone RUs, first to fourth 484-tone RUs, or first and second 996-tone RUs are sequentially arrangeable, allocating a multi-RU comprising a 996-tone RU, a 484-tone RU, and a 242-tone RU to the second device, and
wherein the multi-RU comprises one of eight multi-RUs which include the first to eighth 242-tone RUs, respectively.
