Abstract: This specification provides 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 receives a downlink control channel (Physical Downlink Control Channel (PDCCH)) including downlink control information (DCI) from an eNB and the DCI includes an indicator indicating whether a preamble format of a random access preamble allocated to the UE is format 0/1 or format 2. Then, the UE transmits the random access preamble to the eNB in a subcarrier allocated to the UE according to the preamble format and receives a random access response from the eNB in response to the random access preamble.

Abstract: One disclosure in the present specification presents a method for a wireless device to receive a paging message. The method may comprise: a step of deciding a wake up signal occasion (WUSO) window for attempting to receive a wake up signal (WUS); and a step of monitoring a downlink control channel during a paging window so as to attempt to receive a paging message, if the WUS is received within the decided WUSO window. Here, the WUSO window may be decided according to a duration size and offset.
