Abstract: A method and apparatus for performing transmission in a wireless communication system is provided. A narrowband internet-of-things (NB-IoT) user equipment (UE) transmits a physical uplink shared channel (PUSCH) to a network by using a first resource unit, and transmits an acknowledgement/non-acknowledgement (ACK/NACK) to the network by using a second resource unit. The first resource unit for PUSCH transmission consists of a first number of resource elements (REs) within a first tone in frequency domain and a first time interval in time domain. The second resource unit for ACK/NACK transmission also consists of a second number of REs within a second tone in frequency domain and a second time interval in time domain. The second number is smaller than the first number.

Abstract: The present disclosure provides a method of receiving a physical downlink shared channel (PDSCH) by a user equipment (UE) in a wireless communication system. The method may include: receiving a parameter related to discontinuous reception (DRX) operation through a higher layer; receiving first downlink control information (DCI) including information related to physical downlink control channel (PDCCH) monitoring adaptation; receiving second DCI for scheduling the PDSCH within a DRX active time of the DRX operation, based on the information related to the PDCCH monitoring adaptation; and receiving the PDSCH based on the second DCI. The PDCCH monitoring adaptation may be determined based on jitter related to the PDSCH.

Abstract: A method for controlling, by a user equipment (UE), a transmit power in a narrowband (NB) wireless communication system is disclosed. The method includes receiving, from a base station, a preconfigured uplink (UL) resource (PUR) configuration, transmitting, to the base station, uplink data on the PUR, and receiving, from the base station, feedback information for the uplink data. A transmit power of the uplink data is controlled based on a number of receptions of the feedback information.

Abstract: The present specification provides a method for transmitting and receiving downlink control information (DCI) in a wireless communication system supporting narrow band-Internet of things (NB-IoT). Specifically, a terminal monitors at least one first candidate PDCCH in a first search space and at least one second candidate PDCCH in a second search space, wherein the first search space and the second search space may partially or entirely overlap each other on a time axis. Thereafter, the terminal may search for a first DCI in the at least one first candidate PDCCH and a second DCI in the at least one second candidate PDCCH, wherein the sum of the number of the at least one first candidate PDCCH and the number of the at least one second candidate PDCCH may be less than or equal to a specific number.
