1. A method of transmitting a synchronization signal, the method comprising:

  • generating a first code sequence by using a first number and a second code sequence by using a second number for synchronization of UE (User Equipment) within a cell;

    mapping the first code sequence to resource elements (REs) in a first orthogonal frequency-division multiplexing (OFDM) symbol and the second code sequence to REs in a second OFDM symbol; and

    transmitting the mapped first code sequence and the mapped second code sequence, wherein the first OFDM symbol is ‘

    n’

    OFDM symbol ahead from the second OFDM symbol,wherein the first code sequence is generated from a first number and the second code sequence is generated from a second number,wherein a combination of the first number and the second number indicates an identity of the cell, andwherein the first number is related to a cell group identifier for identifying a cell group including the cell and the second number is related to a cell identifier for identifying the cell included in the cell group identified by the cell group identifier.
