1. A wireless communication terminal comprising:
a transceiver; and
a processor,
wherein the processor performs respective contention procedures in a plurality of channels in an unlicensed band, and performs, by using the transceiver, transmission in a first channel of the plurality of channels based on a contention procedure in the first channel and transmission in a second channel of the plurality of channels based on a contention procedure in the second channel,
wherein the contention procedure in the first channel and the contention procedure in the second channel are performed independently of each other.
