Abstract: The present application discloses a method for transmitting a signal by a transmission terminal using direct device-to-device communication in a multicarrier communication system. Specifically, the method comprises the steps of: transmitting first data and first control information for the first data to a reception terminal via a first carrier; and transmitting second data and second control information for the second data to the reception terminal via a second carrier, wherein the first control information includes multicarrier-related information indicating at least one among an indicator indicating whether transmission is multicarrier transmission via the first carrier and the second carrier, an identifier of the transmission terminal, and an indicator indicating whether transmission timing of the first carrier and transmission timing of the second carrier coincide.

Abstract: Disclosed is a method for determining, by a terminal, a transmission resource pool in device-to-device (D2D) communication. The method for determining a transmission resource pool comprises the steps of: indexing resource blocks within a resource block pool; and mapping the indexed resource blocks to physical resource blocks, wherein the indexed resource blocks are arranged in order of increasing resource block index, the resource block pool is used to transmit D2D signals, and information about the configuration of the resource block pool can be indicated by upper layer signaling.

Abstract: A method for transmitting a physical sidelink shared channel (PSSCH), by a device-to-device (D2D) terminal, in a wireless communication system involves receiving a physical sidelink control channel (PSCCH) and a PSSCH transmitted in a resource region indicated by the PSCCH. If an energy measurement value with respect to the PSSCH is greater than a preset threshold, the method further involves selecting a transmission resource excluding the resource region in which the PSSCH has been transmitted; and transmitting a D2D signal by means of the selected transmission resource, wherein the threshold has a value that varies in accordance with whether or not the PSSCH is retransmission or the redundancy version (RV) of the PSSCH.
