1. A method for transmitting a synchronization signal by a user equipment (UE) in a wireless communication system supporting a sidelink, the method comprising:
generating a primary sidelink synchronization signal (PSSS) and a secondary sidelink synchronization signal (SSSS); and
transmitting the PSSS, the SSSS and a Physical Sidelink Broadcast Channel (PSBCH) in a subframe,
wherein the subframe includes a first Orthogonal Frequency Division Multiplexing (OFDM) symbol for a transmission of the PSSS and a second OFDM symbol for a transmission of the PSBCH, and a third OFDM symbol for a transmission of the SSSS,
wherein a transmission power of the PSSS in the first OFDM symbol is determined based on a first number of resource units (REs) in which the PSSS is mapped to the first OFDM and a second number of REs in which the PSBCH is mapped to the second OFDM symbol,
wherein the transmission power of the PSSS in the first OFDM symbol is the same as a transmission power of the PSBCH in the second OFDM symbol, and
wherein the first number is 62, and the second number is 72.
