Abstract: A method for receiving a signal by an apparatus in a wireless communication system is discussed. The method includes receiving, in a first time resource within a second time resource configured as 14 number of symbols, a physical channel carrying downlink control information within resource element groups (REGs), and receiving a physical downlink shared channel based on the downlink control information. Further, the REGs are indexed starting from a symbol included in the first time resource, and a starting boundary of the first time resource is determined independently from a starting boundary of the second time resource.

Abstract: Disclosed in the present application is a method by which a first terminal transmits a side link signal to a second terminal in a wireless communication system. Particularly, the method for transmitting a side link signal comprises the steps of: transmitting, in a first number of transmission time units, a control signal, which includes resource allocation information of a data signal, and a first reference signal for the control signal; and transmitting, in a second number of transmission time units, the data signal and a second reference signal for the data signal, wherein the transmission time units have two or more symbols, the first reference signal is transmitted in fixed symbol indexes irrespective of the first number of transmission time units, and symbol indexes in which the second reference signal is transmitted are determined on the basis of the second number of transmission time units.

Abstract: Provided are a method for a terminal transmitting an uplink control channel in a wireless communication system, and a device using same. The method comprises: determining the overlapping or not between a first physical uplink control channel (PUCCH) and a second PUCCH; and determining a transmission method for the first PUCCH and the second PUCCH on the basis of the determining. Here, the first PUCCH is an uplink control channel that is frequency division multiplexed (FDM) with a data channel, and the second PUCCH is an uplink control channel that is time division multiplexed (TDM) with the data channel.

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.
