1. A wireless communication terminal for accessing a plurality of contention-based channels, the terminal comprising:
a processor, and
a memory coupled with the processor,
wherein the processor is configured to:
perform backoff procedure for a plurality of channels,
wherein each of a plurality of backoff counters individually corresponding to a respective channel of the plurality of channels is determined within a contention window, and
wherein an initial value of each of the plurality of backoff counters is set based on a common backoff counter used by the wireless communication terminal for multi-channel access, and
perform multi-channel transmission through the plurality of channels based on the backoff procedure using the plurality of backoff counters,
wherein the multi-channel transmission is performed through the plurality of channels when the plurality of backoff counters are ‘0’, and
wherein a size of the contention window is adjusted depending on whether the multi-channel transmission is successful.
