Abstract
The present disclosure relates to a wireless communication system, and more particularly to a method for transmitting synchronization channel and cell search signal in wireless communication system. Synchronization channel and cell search signal allow a terminal in a multi-layer cell supporting multiple carriers to effectively search and distinguish cells at different frequencies. To minimize terminal power consumption, new cell search signal transmission method proposes that base station connected at a frequency be used for transmitting information by other base stations at different frequencies, thereby allowing the terminal to readily recognizing neighbor cells and to determine about performing additional cell search. For the multi-layer cell to clearly distinguish cell identifications including inter-frequency measurement information, a cell ID pair between macro/small cells is proposed, achieving enhanced small cell efficiency. An uplink centralized transmission frame supports a multi-layer cell based on TDD, proposing a method for configuring synchronization signal in corresponding frame.
