1. A wireless communication terminal that communicates wirelessly, the terminal comprising:
a transceiver; and
a processor,
wherein the processor is configured to:
receive a signaling field of a PLCP Protocol Data Unit (PPDU) through the transceiver,
obtain a Basic Service Set (BSS) color field from the signaling field, wherein the BSS color field indicates a BSS color which identifies a BSS,
obtain an Address field of a MAC header from the PPDU,
determine that the PPDU includes an Inter-BSS frame when the BSS color indicated by the BSS color field is the same as a BSS color 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),
wherein the BSS color of the BSS including the wireless communication terminal is signaled by a base wireless communication terminal which is associated with the wireless communication terminal.
