1. A method in a wireless local area network (WLAN) system, the method comprising:
receiving, by a receiving station (STA), a Physical Protocol Data Unit (PPDU) from a transmitting STA; and
decoding, by the receiving STA, the PPDU,
wherein the receiving STA is a 20 MHz operating non-AP STA,
wherein the 20 MHz operating non-AP STA does not support a first multiple-resource unit (MRU),
wherein, based on a bandwidth of the PPDU being 40 MHz, the bandwidth of the PPDU consists of first to 18th 26 tone RUs, first to 8th 52 tone RUs, first to 4th 106 tone RUs, or first and second 242 tone RUs,
wherein the first MRU includes a first MRU type and a second MRU type,
wherein the first MRU type is a 52+26-tone MRU corresponding to MRU combinations of the 52+26-tone MRU,
wherein the MRU combinations of the 52+26-tone MRU includes an MRU including the second 52 tone RU and the 5th 26 tone RU, and an MRU including the 6th 52 tone RU and the 14th 26 tone RU,
wherein the second MRU type is a 106+26-tone MRU corresponding to MRU combinations of the 106+26-tone MRU, and
wherein the MRU combinations of the 106+26-tone MRU includes an MRU including the first 106 tone RU and 5th 26 tone RU, an MRU including the second 106 tone RU and the 5th 26 tone RU, an MRU including the 3rd 106 tone RU and the 14th 26 tone RU, and an MRU including the 4th 106 tone RU and the 14th 26 tone RU.
