1. A wireless communication terminal comprising:a transceiver configured to transmit and receive wireless signals; and
a processor configured to process wireless signals transmitted or received through the transceiver,
wherein the processor is configured to:
receive a first packet through the transceiver,
measure a received signal strength of the first packet,
determine whether the first packet is a packet of a basic service set (BSS) with which the terminal is associated or a packet of a different BSS from the BSS with which the terminal is associated, and
access a channel based on the received signal strength of the first packet when the first packet is determined to be the packet of the different BSS from the BSS with which the terminal is associated.
