摘要： A method for transmitting a signal by a Device-to-Device (D2D) User Equipment (UE) in a wireless communication system includes mapping block of complex-valued symbols to Physical Resource Blocks (PRBs) based on a subband based-frequency hopping related to an uplink frequency hopping; generating a Single Carrier Frequency Division Multiple Access (SC-FDMA) signal; and transmitting the SC-FDMA signal. Further, a slot index for the subband based-frequency hopping is re-indexed based on subframe indexes re-indexed within a D2D resource pool based on the block of complex valued symbols for a D2D communication signal.
