1. A wireless communication terminal that communicates wirelessly, the terminal comprising:a transceiver; and
wherein the processor is configured to
receive a signaling field of a Physical Layer Convergence Protocol (PLCP) Protocol Data Unit (PPDU) through the transceiver,
obtain an Address field of a MAC header from the PPDU,
determine that the PPDU includes an Inter-Basic Service Set (BSS) frame when information identifying a BSS indicated by the signaling field is the same as information identifying a BSS of a BSS including the wireless communication terminal, and the obtained Address field of the MAC header indicates a BSS which is different from the BSS including the wireless communication terminal as a BSS from which the PPDU is transmitted, and
access a channel based on the determination that the PPDU includes an Inter-BSS frame,
wherein the Address field of the MAC header indicates a MAC address related to a MAC Protocol Data Unit (MPDU).
