Abstract: This specification provides a method for transmitting an NPRACH preamble in a wireless communication system supporting TDD. More specifically, the method performed by the UE includes: receiving, from a base station, NPRACH configuration information including control information for a repetition number of NPRACH preambles including symbol groups through a higher layer signaling; and transmitting, to the base station, the NPRACH preamble repeatedly through frequency hopping of a symbol group based on the NPRACH configuration information, in which a frequency location of the symbol group is determined based on a first parameter related to a start subcarrier and a second parameter related to the frequency hopping.

Abstract: This specification provides a method of receiving system information in a wireless communication system supporting a TDD narrowband. More specifically, the method performed by a user equipment includes receiving, from a base station, first system information on an anchor carrier, the first system information includes first information indicating whether a carrier used for second system information is an anchor carrier or a non-anchor carrier and second information on a location of the non-anchor carrier used for the second system information, and receiving, from the base station, the second system information on the non-anchor carrier based on the first system information. Accordingly, an SIB1-NB is transmitted and received even on a non-anchor carrier.

Abstract: According to one embodiment, a distance technique between a transmitter and a receiver for processing a signal in symbol units is presented. According to the embodiment, the transmitter transmits a transmission signal to the receiver through preset first and second frequencies. Then, the transmitter receives, from the receiver, a reception signal corresponding to the transmission signal. The reception signal includes a first reception component corresponding to the first frequency and a second reception component corresponding to the second frequency. The phase difference set by the receiver is applied between the phase of the first reception component and the phase of the second reception component. The phase difference is set on the basis of the difference between a reception time at which the transmission signal is received by the receiver and a processing time at which the transmission signal is processed in the receiver.
