Abstract: A method for transmitting a signal by a Device-to-Device (D2D) User Equipment (UE) is disclosed. The method includes mapping a block of complex-valued symbols to Physical Resource Blocks (PRBs), and generating and transmitting a Single Carrier Frequency Division Multiple Access (SC-FDMA) signal after the mapping. If frequency hopping is used during the mapping, a lowest PRB index of the PRBs is changed between a first PRB index and a second PRB index according to a change in a transmission number for a transport block. If the block of complex-valued symbols is a D2D communication signal, the transmission number for the transport block is replaced with a subframe index of a D2D resource pool.
