Abstract

This invention provides a method and apparatus for receiving PPDU in a wireless LAN system. [Solution] The receiving STA (station) receives a PPDU (Physical Protocol Data Unit) from the transmitting STA via broadband S2710 and decodes the PPDU S2720. The PPDU includes a control field and a data field. If the broadband is a 320 / 160+160MHz band including a primary 160MHz channel and a secondary 160MHz channel, the data field is received via a first multiplexed RU aggregated from 996RUs and 484RUs. The first multiplexed RU is allocated within the primary 160MHz channel or the secondary 160MHz channel.
