Claim of US Patent No. 10,701,732

1. A wireless communication terminal comprising:a transceiver configured to transmit and receive a wireless signal; and
a processor configured to control an operation of the terminal,
wherein the processor is configured to:
perform a backoff procedure of a channel for data transmission,
suspend the backoff procedure when a wireless signal having a signal strength higher than a predetermined first threshold is received through the channel,
identify whether the received wireless signal is a wireless signal of the same basic service set (BSS) as a BSS with which the terminal is associated, and
determine whether to resume the backoff procedure based on a second threshold according to the identification result,
wherein when the received wireless signal is identified as not being the wireless signal of the same BSS as the BSS with which the terminal is associated, the processor determines whether to resume the backoff procedure, which is suspended based on the first threshold, using the second threshold, and
wherein the second threshold is set distinctly from the first threshold.
