Method for transceiving broadcast channel signals in a wireless communication system and apparatus thereof

A signal transmission device in a wireless communication system, the device comprising:

• a processor configured to set a multiplexed block by multiplexing a PSS (primary synchronization signal), an SSS (secondary synchronization signal), and a PBCH (physical broadcast channel) signal in time frequency domain,
• wherein, when the PBCH signal is multiplexed with the PSS and the SSS in a TDM (Time Divisional Multiplexing) scheme on different OFDM symbols, the processor controls the PBCH signal to be transmitted through wider bandwidth comparing to a bandwidth for transmitting the PSS and the SSS, and
• wherein, when the PBCH signal is multiplexed with the SSS in a FDM (Frequency Divisional Multiplexing) scheme on a same OFDM symbol, the processor controls the PBCH signal to be transmitted through frequency bands of both ends adjacent to a frequency position at which the SSS is transmitted;
• and
• a transceiver configured to transmit the multiplexed block to a receiving side device.
