Method and apparatus for transmitting synchronization signal in wireless communication system

A method for performing, by a user equipment, synchronization in a wireless communication system, the method comprising:

• receiving, from a base station, a primary synchronization signal (PSS) and a secondary synchronization signal (SSS) through a macro node;
• receiving, from the base station, a third synchronization signal (TSS) through at least one radio remote head (RRH) having a cell identity (ID) that is identical to a cell ID of the macro node;
• performing time synchronization with the macro node based on the PSS and the SSS;
• performing time synchronization with the at least one RRH based on the TSS;
• reporting, to the base station, first information on the time synchronization with the macro node and the time synchronization with the at least one RRH;
• receiving, from the base station as a response to the first information, second information on a delay between a last symbol of a control channel transmitted by the base station through the macro node and an initial symbol of a data channel transmitted by the base station through the at least one RRH;
• and
• decoding the control channel and the data channel based on the second information.
