Abstract: The present invention discloses a method for obtaining information for a cyclic prefix (CP) in a wireless communication system by a terminal and a device for the same. Specifically, a method for obtaining information for a cyclic prefix (CP) in a wireless communication system by a terminal includes: detecting a specific synchronization signal received from a base station via a first symbol of a first subframe; detecting the specific synchronization signal received from the base station via a second symbol of a second subframe; and obtaining information for the CP applied to transmission of the specific synchronization signal based on an offset value between an index of the first symbol and an index of the second symbol.

Abstract: In the transmission of a narrowband positioning reference signal (NPRS), by a base station, in a cellular mobile communication system supporting narrowband-Internet of Things (NB-IoT), the base station transmits an NPRS by using a predetermined part of a sequence defined by a generation formula, which is the same as a positioning reference signal (PRS) generation formula, and when a PRS and the NPRS are transmitted through the same cell, the base station transmits, to a terminal, information indicating whether the PRS and the NPRS can be used together.

Abstract: Disclosed herein is a method of transmitting a reference signal for channel state change measurement and an apparatus therefor. The method includes receiving, from a transmitter, a first type reference signal of a first resource mapping pattern and a second type reference signal of a second resource mapping pattern. The receiver receives the first type reference signal under an assumption that the first type reference signal is associated with the second type reference signal, when a specific condition is satisfied.

Abstract: The present disclosure provides a method for transmitting a random access channel (RACH) by a UE in a wireless communication system. Particularly, the method includes receiving information about actually transmitted synchronization signal blocks (SBBs) and RACH configuration information about RACH resources and transmitting a RACH in at least one RACH resource among RACH resources mapped to actually transmitted SSBs on the basis of the information about actually transmitted SSBs and the RACH configuration information, wherein the actually transmitted SSBs are repeatedly mapped to RACH resources by a positive integer multiple of the number of the actually transmitted SSBs in a RACH configuration period based on the RACH configuration information.

Abstract: A method and a device to transmit a reference signal (RS) in a wireless communication system are disclosed. The device transmits control information and a first type RS for demodulating the control information through a control region comprising 1 first OFDM (Orthogonal Frequency Division Multiplexing) symbol of a subframe; and transmits data through a data region comprising a predetermined number of OFDM symbols following the control region of the subframe. Here, the first type RS can be used also for demodulating the data when a predetermined condition is met.
