Abstract: Provided is a method for transmitting a random access preamble by a user equipment (UE) in a wireless communication system supporting a narrow band-Internet of things (NB-IoT). Specifically, the UE transmits the random access preamble to an eNB in a subcarrier allocated by the eNB according to a specific preamble structure and receives a random access response message from the eNB in response to the random access preamble. In this case, the random access preamble is repeatedly transmitted 16 times during a predetermined duration and then, a gap is inserted for a predetermined time and the predetermined duration is determined by multiplying a transmission duration in which the random access preamble is transmitted by the number of repeated transmission times.

Abstract: The present invention relates to a method for receiving a downlink signal and an apparatus therefor. Specifically, the method for receiving a downlink signal comprises the steps of: receiving first time offset information and second time offset information from a base station, wherein the first time offset information and the second time offset information each indicate the time offset between the reception time of a specific signal and the reception time of a specific channel associated with the specific signal, and the first time offset information is set to have a length shorter than that of the second time offset information; and monitoring the specific signal at a time position determined on the basis of one of the first time offset information and the second time offset information, wherein the one offset information is determined on the basis of the capability of a user device.

Abstract: Provided are a method of adjusting uplink timing in a wireless communication system and an apparatus therefor. Specifically, a method for a user equipment to adjust uplink timing in a wireless communication system includes transmitting, to a base station, an uplink signal, receiving, from the base station, a timing advance (TA) command configured based on the uplink signal, and performing uplink transmission to the base station by applying a timing advance (TA) indicated by the TA command. The TA command may be interpreted based on subcarrier spacing of at least one frequency resource region to which the TA is to be applied.

Abstract: The present disclosure provides a method for a terminal to receive a physical downlink shared channel (PDSCH) in a wireless communication system supporting a narrow band-internet of things (NB-IoT). Specifically, the terminal receives a first physical downlink control channel (PDCCH) including first downlink control information (DCI) from a base station and receives a first PDSCH on the basis of the first DCI. Here, the first PDSCH may include indication information indicating whether a multi transport block is scheduled. The terminal receives a plurality of PDSCHs from the base station, wherein at least one PDSCH of the plurality of PDSCHs may be received without receiving a separate DCI according to the indication information.
