METHOD AND APPARATUS OF TRANSMITTING REFERENCE SIGNAL IN WIRELESS COMMUNICATION SYSTEM

摘要

PURPOSE: A reference signal transmission method and a method thereof are provided to maintain backward compatibility by transmitting a reference signal by avoiding a synchronization signal or a physical broadcast channel. CONSTITUTION: A first synchronization signal or a second synchronization signal is transmitted from a sub frame including a plurality of OFDM symbols. A plurality of reference signals are transmitted through a plurality of antenna from the sub frame. The reference signals are transmitted without the duplication with a PSS(Primary Synchronization Signal) or a SSS(Secondary Synchronization Signal) transmitted from the sub frame. A plurality of reference signals, the PSS, or the SSS is transmitted without duplication in at least one among a plurality of OFDM symbols.
