1. A method in a wireless local area network (WLAN) system, the method comprising:
generating, by a transmitting station (STA), a Physical Protocol Data Unit (PPDU) including a data field; and
transmitting, by the transmitting STA, the PPDU to a receiving STA,
wherein the data field is transmitted through a Multiple-Resource Unit (MRU),
wherein Low Density Parity Check (LDPC) tone mapping is performed in the MRU based on a DTM,
wherein based on a size of the MRU being a 484+242 tone MRU, the DTM is 18,
wherein based on the size of the MRU being a 52+26 tone MRU, the DTM is 4,
wherein based on the size of the MRU being a 106+26 tone MRU, the DTM is 6, and
wherein the DTM is a distance parameter for data tones in the MRU.
