METHOD AND APPARATUS FOR TRANSMITTING REFERENCE SIGNAL IN WIRELESS COMMUNICATION SYSTEM INCLUDING RELAY STATION

摘要

Provided are a method and an apparatus for transmitting a reference signal in a wireless communication system including a relay station. A base station respectively generates a plurality of reference signals for a plurality of antenna ports, maps the plurality of reference signals into relay zones within at least one resource block according to predetermined reference signal patterns, and transmits the at least one resource block through the plurality of antenna ports. At this point, the plurality of reference signals includes at least one cell-specific reference signal (CRS) of a 3rd Generation Partnership Project (3GPP) Long-Term Evolution (LTE) Rel-8 system.
