Abstract: According to one embodiment of the present invention, a method by which a terminal transmits uplink data by using a preconfigured uplink resource (PUR) in a wireless communication system supporting a narrowband Internet of Things (NB-IoT) system comprises the steps of: receiving information related to the PUR for transmitting uplink data in an RRC connected state; and transmitting the uplink data by using the PUR in an RRC idle state. The information related to the PUR includes information indicating a particular carrier for monitoring a first search space related to the PUR, and when the first search space overlaps a second search space in which downlink control information (DCI) related to a particular operation is transmitted, the second search space has priority.

Abstract: A method of performing channel access on an unlicensed band by a user equipment, includes sensing a carrier of an unlicensed band for transmitting an uplink signal; and transmitting the uplink signal when power detected by sensing the carrier is less than an energy detection threshold that is configured by the user equipment, wherein the energy detection threshold is configured to be equal to or less than a maximum energy detection threshold determined by the user equipment, the maximum energy detection threshold is determined adaptively to a bandwidth of the carrier using a decibel value of a ratio between a reference bandwidth and the bandwidth of the carrier, and the maximum energy detection threshold is configured to be equal to or greater than a first power value which is a sum of a lower bound of the maximum energy detection threshold for the reference bandwidth and the decibel value.

Abstract: Provided are a method for transmitting uplink control information (UCI) of a terminal in a wireless communication system and the UE using the method. The method includes determining a number of coded symbols for the UCI transmission and transmitting the UCI on a physical uplink shared channel (PUSCH) based on the number of coded symbols. The number of coded symbols is determined among a first value based on a payload size of the UCI and an offset value and a second value based on a radio resource control (RRC) signal.
