Abstract
The present specification provides a method for transmitting a narrowband physical random access channel (NPRACH) preamble in a narrow band (NB)-Internet of things (IoT) system supporting a frame structure type 2.More specifically, the method performed by a user equipment includes receiving, from a base station, control information related to an uplink-downlink configuration; and transmitting, to the base station, the NPRACH preamble based on parameters related to a NPRACH preamble transmission related to the received control information.
