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: The present specification provides a method for transmitting and receiving physical signals and/or channels in a wireless communication system and an apparatus therefor. Specifically, a method for a terminal to receive a wireless signal and/or a channel in a wireless communication system may comprise the steps of: receiving, from a base station, downlink control information (DCI) for scheduling for one or more wireless signals and/or channels; and cross-receiving the one or more wireless signals and/or channels on a sub-block basis from the base station on the basis of the DCI.

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.

Abstract: The present specification proposes a method for transmitting or receiving emergency information in a wireless communication system supporting machine type communication and a device therefor. Specifically, the method performed by a terminal may comprise the steps of: receiving discontinuous reception (DRX)-related information from a base station through radio resource control (RRC) signaling; receiving a paging message from the base station on the basis of the DRX-related information; and transmitting a physical random access channel (PRACH) preamble to the base station on the basis of the paging message emergency.
