Abstract: Performing a random-access channel procedure (RACH procedure) by a terminal in an unlicensed band. Specifically, a method may include: transmitting message A including a first physical random-access channel (PRACH) and a first physical uplink shared channel (PUSCH) to a base station; and receiving contention resolution-related message B from the base station in response to message A, wherein a power ramping counter is used to configure transmission power of message A, and the power ramping counter has a value which increases based on that a transmission spatial beam for transmission of message A is configured to be identical to a transmission spatial beam related to transmission of a PRACH preceding message A.

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 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.
