1. A station (STA), the STA comprising:
a processor; and
a communication unit,
wherein the processor is configured to:
receive, through the communication unit, a physical layer protocol data unit (PPDU) including a trigger frame,
identify whether the PPDU is an intra-BSS (basic service set) PPDU or an inter-BSS PPDU,
wherein one or more resource units (RUs) allocated to the STA based on the trigger frame are allocated only within a primary channel of a specific channel when the STA operates in a specific subchannel.
