Abstract: A method of performing channel access on an unlicensed band by a user equipment in a wireless communication system, includes sensing a carrier of an unlicensed band for receiving a downlink signal; and receiving the downlink signal when power detected by sensing the carrier is less than an energy detection threshold that is configured by a base station, wherein the energy detection threshold is configured to be equal to or less than a maximum energy detection threshold determined by the base station, and wherein when a different radio access technology (RAT) sharing the carrier is able to exist, 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.

Abstract: The disclosure of the present specification provides a method for performing a narrowband physical uplink shared channel (NPUSCH) transmission. The method may comprise: determining a start position of the NPUSCH transmission; performing the NPUSCH transmission, if the start position of the NPUSCH transmission is determined as a first of two contiguous subframes; and postponing the NPUSCH transmission, if the start position of the NPUSCH transmission is determined as a second of the two contiguous subframes. The two contiguous subframes may be configured as a time division duplex (TDD) uplink subframe based on at least one of TDD configurations 1 and 4. The two contiguous subframes may be defined for a subcarrier spacing of 3.75 kHz.

Abstract: The present specification provides a method for transmitting multiple uplink control information (UCI) on a physical uplink control channel (PUCCH) in a wireless communication system. More specifically, the method performed by a user equipment (UE) includes receiving, from a base station, control information related to PUCCH resources for transmitting the multiple UCI, wherein the control information includes information related to a number of REs of the PUCCH resources, information related to a modulation order, and information related to a configured maximum code rate; determining a PUCCH resource for transmitting the multiple UCI by comparing a value obtained by multiplying the configured maximum code rate and the modulation order by the number of REs corresponding to the PUCCH resources indexed in ascending order with a size of a payload for the multiple UCI; and transmitting, to the base station, the multiple UCI on the determined PUCCH resource.
