Abstract: A method and a device for transmitting an uplink transmission block in a wireless communication system are provided. Particularly, a terminal receives, from a base station, allocation information on a first grant-free uplink resource, which is scheduled semi-persistently. The terminal repeatedly transmits a first transmission block through the first grant-free uplink resource by using a first reference signal. The terminal transmits a second transmission block by using a second reference signal before completion of the transmission of the first transmission block. The second transmission block is distinguished from the first transmission block through a change of the first reference signal to the second reference signal.

Abstract: A method of receiving Downlink (DL) data by a User Equipment (UE) in a wireless communication system. The method includes: receiving information related to a number of repetitions of the DL data which is repeatedly transmitted in (i) at least one first Transmission Time Interval (TTI) included in a first subframe, and in (ii) at least one second TTI included in a second subframe that is after the first subframe; and receiving the DL data based on the number of repetitions of the DL data. If a Transmission Mode (TM) for the first subframe is different from a TM for the second subframe, then the UE does not receive the DL data in the at least one second TTI.

Abstract: The present disclosure provides a method for mapping a reference signal (RS) sequence to a physical resource in a wireless communication system. Specifically, the method performed by a terminal comprises the steps of: receiving, from a network, length information indicating a length of the RS sequence and offset information indicating a start position of the RS sequence mapped to the physical resource allocated to the terminal; generating the RS sequence on the basis of the received length information; and mapping the generated RS sequence to the physical resource on the basis of the offset information.

Abstract: Provided are a method for managing a beam performed by a terminal in a wireless communication system and a device using the method. According to the method, the terminal performs a power saving operation on a first cell and receives a PDCCH through a second cell, wherein the PDCCH requests to measure a reference signal transmitted aperiodically in the first cell. The reference signal is received at a particular time for a DRX cycle related to the power saving operation. The terminal generates beam related information to be used in the first cell by measuring the reference signal in the first cell.
