Abstract: The present specification discloses an invention relating to a method for transmitting an MTC physical downlink control channel (MPDCCH) by a base station in a wireless communication system supporting machine type communication (MTC). According to the present invention, a base station transmits, to a terminal, configuration information related to the transmission of an MPDCCH and maps the MPDCCH onto multiple resource elements (REs) of at least one first symbol constituting a first slot of a special subframe. The special subframe is a subframe in which, among symbols constituting the subframe, the number of symbols for data transmission is smaller than or equal to a predetermined number. The base station transmits the MPDCCH to the terminal over the multiple resource elements, wherein the mapping step is performed by copying at least one second symbol of a second slot adjacent to the first slot onto the at least one first symbol.

Abstract: A method, performed by a user equipment (UE), for performing an initial access procedure in an unlicensed band includes: performing the initial access procedure with a base station; and performing transmission of a physical uplink shared channel (PUSCH) on the basis of the performing of the initial access procedure, wherein the UE obtains, from the base station, information about a listen before talk (LBT) type and information about a PUSCH starting position, and the UE performs the transmission of the PUSCH on the basis of the information about the LBT type and the information about the PUSCH starting position. The information about the PUSCH starting position is information indicating one position among a plurality of PUSCH starting position candidates. The information about the LBT type indicates one of a LBT type 1, a LBT type 2, and a LBT type 3.

Abstract: Provided are a method and a device for reporting channel state information (CSI) in a wireless communication system. A wireless device receives a first uplink grant for indicating that a transmission of a physical uplink shared channel (PUSCH) is triggered by a second uplink grant in a first subframe on a Licensed-Assisted Access (LAA) cell. The first uplink grant requests a report of an aperiodic CSI. The wireless device computes the aperiodic CSI based on a valid subframe no later than the first subframe in which the first uplink grant is received.
