Wireless communication method and wireless communication terminal for spatial reuse operation

A wireless communication terminal, the terminal comprising:

• a processor;
• and
• a communication unit,
• wherein the processor is configured to:
• receive a PHY protocol data unit (PPDU) through the communication unit,
• determine whether the PPDU contains an intra-BSS(Basic Service Set) frame or an inter-BSS frame based on at least one of a first specific condition or a second specific condition,
• wherein the first specific condition is used to determine whether the PPDU includes the inter-BSS frame, the second specific condition is used to determine whether the PPDU includes the intra-BSS frame, and whether the PPDU includes the intra-BSS frame or the inter-BSS frame is determined by a condition of a MAC address among the first specific condition and the second specific condition when the PPDU satisfies both the first specific condition and the second specific condition, and
• perform either a first operation or a second operation distinct from each other according to a determination result.
