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 for performing a random access process in an unlicensed band, and a device using the same. The device receives a random access preamble (RAP) order instructing the transmission of a RAP. The device performs a clear channel assessment (CCA) in an unlicensed cell during an RAP window so as to transmit the RAP when the device succeeds in CCA.

Abstract: A method for transmitting a data demodulation reference signal (DMRS) in a wireless communication system and a device therefor are disclosed. To this end, a basic DMRS is transmitted via the first OFDM symbol in a data transmission region of a predetermined subframe, and an additional DMRS is transmitted in the predetermined subframe in accordance with a level determined by a transmission environment, wherein the basic DMRS is characterized by being transmitted via the first OFDM symbol in the data transmission region of the predetermined subframe regardless of a transmission link, the structure of the subframe, and the transmission environment.

Abstract: A method for a user equipment (UE) in a wireless communication system includes monitoring a physical channel carrying downlink control information (DCI); and receiving, based on the DCI, downlink data in an unlicensed band cell (Ucell). Further, the downlink data is received in a 1st subframe of a downlink transmission burst, based on being configured to monitor the physical channel on the Ucell, the downlink data is received starting in one of a partial subframe or a normal subframe in the 1st subframe, and the partial subframe is smaller than the normal subframe.
