Abstract: The present description provides a method for transmitting a scheduling request (SR) in a low-capability (LC) or low-cost (LC) device. The method can comprise a step for receiving an upper layer signal comprising an SR subframe offset and an SR transmission period. The upper layer signal can further comprise information about the number of repetitions. Also, the method can comprise the steps of: determining, on the basis of the SR transmission period and SR subframe offset, a subframe on which the SR is to be transmitted; determining the number of repeated transmissions of the SR on the basis of the information; and transmitting the SR on the determined subframe. The SR can repeatedly be transmitted on a plurality of subframes that begin from the determined subframe.

Abstract: Disclosed are a method for performing an initial access in a wireless communication system, and an apparatus therefor. Specifically, a method by which a terminal performs an initial access comprises the steps of: receiving, from a base station, configuration information representing one or more physical random access channel (PRACH) configurations; receiving, from the base station, downlink control information including information indicating a specific PRACH configuration among the one or more PRACH configurations, through a physical downlink control channel; and transmitting a preamble and/or data, which are related to the initial access, to the base station through a PRACH on the basis of the specific PRACH configuration.

Abstract: A disclosure of the present specification provides a method for transmitting a hybrid automatic repeat request (HARQ) ACK/NACK signal in a narrowband Internet of things (NB-IoT) communication. The method may comprise a step of modulating at least one of a first and a second HARQ ACK/NACK signal by two HARQ processes. The step of modulating may comprise a step of mapping at least one of the first and the second HARQ ACK/NACK signal onto a constellation having a quadrature phase shift keying (QPSK) form. The first HARQ ACK/NACK signal may be a signal generated by a first HARQ process for a first downlink data through a first narrowband physical downlink shared channel (NPDSCH). The second HARQ ACK/NACK signal may be a signal generated by a second HARQ process for a second downlink data through a second NPDSCH.
