Abstract: In the present specification, disclosed is a method for receiving a synchronization signal by a terminal. The method may comprise the steps of: determining whether a first synchronization signal from a base station has a higher priority than that of a second synchronization signal from a global navigation satellite system (GNSS) when a terminal has capability to receive the second synchronization signal from the GNSS; and transmitting a sidelink synchronization signal (SLSS) when it is determined that the first synchronization signal has a higher priority, but a signal strength from the base station is less than or equal to a threshold value.

Abstract: The disclosure of the present invention proposes a method for transmitting a sidelink synchronization signal (SLSS). The method may be performed by a vehicle-to-vehicle (V2V) terminal and comprise: performing measurements during a predetermined evaluation time; determining whether values resulting from performing the measurements are below a threshold value; and if the values resulting from performing the measurements during the predetermined evaluation time are below the threshold value, transmitting the SLSS to a neighboring V2V terminal. If the V2V terminal is in radio resource control (RRC) idle state and if the V2V terminal is configured to use 1.28 s or 2.56 s of a discontinuous reception (DRX) cycle length, the V2V terminal may calculate the predetermined evaluation time by using the number of DRX cycles which is not greater than 3.

Abstract: The present invention provides a method for performing a measurement by a terminal in a wireless communications system having both a macro cell and a small cell. The method for performing a measurement includes the step of receiving CRS (Cellspecific Reference Signal) support information from the macro cell or the small cell which works as a serving cell. The CRS support information may contain the information of a cell sending a CRS causing interference. The method may include the step of receiving respectively a CRS from the macro and a CRS from the small cell. Here, a timing offset may be adjusted between the sub-frame receiving the CRS from the macro cell and the sub-frame receiving the CRS from the small cell.
