1. A method for receiving a signal of a neighboring cell by a Device-to-Device (D2D) terminal in a wireless communication system, the method comprising:
receiving one or more parameters from a serving cell of the D2D terminal, the one or more parameters including a periodicity parameter of the serving cell;
determining a repetition pattern of a resource pool of a neighboring cell in consideration of a relation between the periodicity parameter of the serving cell and a system frame number (SFN) cycle,
wherein, when the periodicity parameter is a value that is not a divisor of the SFN cycle, the D2D terminal determines the repetition pattern by assuming that SFNs of the resource pool are aligned with SFNs of the serving cell; and
receiving the signal of the neighboring cell in the determined repetition pattern of the resource pool.
