Abstract: Present document is related with communication of synchronization signals between base station and terminal. The base station acquires a primary synchronization signal generated using a Constant Amplitude Zero Auto-Correlation (CAZAC) sequence having a root index M and having a length L, and a secondary synchronization signal informing a cell group ID. And, the base station transmits the primary synchronization signal at a last symbol of a specific time domain unit to one or more terminals, and the secondary synchronization signal at a second-to-last symbol of the specific time domain unit to the one or more terminals. Here, the root index M is one among a root index set comprising m0 and m1 meeting “m0+m1=(½*L)*n” or “m0−m1=±(½*L)*n”, where ‘n’ is an integer greater than 0.
