Abstract
A communication technique for fusing 5G communication, which supports a higher data transmission rate than a 4G system, with an IoT technology is provided, and may be applied to an intelligent service (e.g., a smart home, a smart building, a smart city, a smart car, or a connected car, a health care application, a digital education application, a retail business application, a security and a safety related services, or the like) based on the 5G communication technology and the IoT related technology. Accordingly, a method for transmitting an uplink signal by a user equipment (UE) is provided and includes receiving, from a base station, information on a channel sensing type (LBT type), sensing a channel for an unlicensed band based on the information on the channel sensing type, and transmitting, to the base station, the uplink signal in the unlicensed band after sensing of the channel for the unlicensed band.
