    Abstract: The present invention relates to a wireless communication system. In detail, the invention relates to a method for a terminal to transmit a UCI in a carrier aggregation-based wireless communication system, and to an apparatus therefor, wherein the method involves the steps of: forming a first cell group having a PCell; forming a second cell group having one or more SCells; receiving one or more data in the second cell group; and transmitting HARQ-ACK information on the one or more data through a PUCCH, wherein, when the first and second cell groups are managed by an identical base station, the HARQ-ACK information is transmitted in the PCell, and, when the first and second cell groups are managed by different base stations, the HARQ-ACK information is transmitted in the second cell group.

    Abstract: In the present application, a method is disclosed of transmitting a downlink data channel from a base station through a terminal in a wireless communication system. In particular, the method comprises the steps of: mapping the downlink data channel to a transmitting resource of a licensed bandwidth or a transmitting resource of an unlicensed bandwidth; and transmitting the mapped downlink data channel via the terminal. The step of mapping the downlink data channel is characterized by comprising the steps of: applying a frequency priority mapping technique when the downlink data channel is mapped to the transmitting resource of the licensed bandwidth; and applying a time priority mapping technique when the downlink data channel is mapped to the transmitting resource of the unlicensed bandwidth.

    Abstract: The present invention relates to a method for performing a random access process in a wireless communication system, and a device therefor, and relates to a method and a device therefor, the method comprising the steps of: receiving, from a base station, narrowband physical random access channel (NPRACH) configuration information; and repeatedly transmitting an NPRACH preamble on the basis of the received NPRACH configuration information, wherein, if a time gap between a completion time point of the last repeated transmission of the NPRACH preamble and a next subframe is smaller than a guard time, the last repeated transmission of the NPRACH preamble is dropped, or is punctured as much as the difference between the guard time and the time gap in the last repeated transmission of the NPRACH preamble.
