    Abstract: This specification provides a method for performing early data transmission in a random access procedure in a wireless communication system.More specifically, the method performed by a user equipment (UE) includes: receiving, from a base station, a control message including first information indicating whether selection for a second transport size (TBS) smaller than a first TBS for message 3 is permitted and second information for the first TBS; transmitting, to the base station, a request for the EDT by using message 1; receiving, from the base station, message 2 including a UL grant for the message 3; determining a repetition number for the message 3 based on the control message and the UL grant; and transmitting the message 3 to the base station by the repetition number.Therefore, there is an effect that battery consumption of the UE can be reduced.

    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.

    IPC: H04W52/02

    Abstract: Provided are a discontinuous reception (DRX) operation method of a terminal in a wireless communication system and an apparatus applying the method. The method comprises the steps of: receiving, from a base station, first configuration information which indicates a monitoring occasion for detecting first DCI comprising information that indicates whether the terminal has woken up; receiving, from the base station, second configuration information which indicates an operation to be applied to the terminal when the first DCI is not detected; monitoring a first PDCCH in order to detect the first DCI in the monitoring occasion; and when the first DCI fails to be detected in the monitoring occasion, monitoring a second PDCCH for detecting not the first DCI but second DCI in a next DRX-on duration on the basis of the second configuration information.
