Abstract: Disclosed are a method for transmitting a random access preamble in a wireless communication system supporting a narrowband-Internet of things (NB-IoT) and an apparatus therefor. Specifically, the method performed by the terminal may include: receiving, from a base station, first configuration information for a first random access preamble and second configuration information for a second random access preamble; transmitting, to the base station, the first random access preamble by using the first configuration information; and transmitting, to the base station, the second random access preamble based on the second configuration information, when transmission of the first random access preamble satisfies a predetermined criterion, in which any one of the first random access preamble and the second random access preamble may be generated based on a sequence in which all elements are not configured to 1.

Abstract: The present invention relates to a method for receiving a downlink signal and an apparatus therefor. Specifically, the method for receiving a downlink signal comprises the steps of: receiving first time offset information and second time offset information from a base station, wherein the first time offset information and the second time offset information each indicate the time offset between the reception time of a specific signal and the reception time of a specific channel associated with the specific signal, and the first time offset information is set to have a length shorter than that of the second time offset information; and monitoring the specific signal at a time position determined on the basis of one of the first time offset information and the second time offset information, wherein the one offset information is determined on the basis of the capability of a user device.
