Abstract:
The present disclosure relates to a communication method and system for converging a 5th-Generation (5G) communication system for supporting higher data rates beyond a 4th-Generation (4G) system with a technology for Internet of Things (IoT). The present disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. The present disclosure provides a method for transmitting uplink signals, a user equipment (UE), and a base station. The UE determines an LBT type and a starting position of signal transmission according to scheduling information and LBT type of a previous subframe, a current subframe, and a subsequent subframe and whether there is a gap between these subframes.
