1. A method performed by a terminal including a first module and a second module in a wireless communication system, the method comprising:receiving by the first module operating in a licensed frequency band and an unlicensed frequency band, control information on the licensed frequency band from a base station;
identifying, by the first module, channel occupancy time of the unlicensed frequency band by decoding the control information based on a licensed assisted access (LAA) radio network temporary identifier (RNTI) that is for scheduling LAA transmission and reception;
transferring, by the first module the channel occupancy time to the second module operating in the same frequency band as the unlicensed frequency band of the first module; and
stopping, by the second module, sensing of a channel of the unlicensed frequency band during the channel occupancy time.
