The method transmits reference signals via a type 2 relay node in a relay communication system and includes a base station (BS) allocating a plurality of antenna ports in a mutually exclusive manner so that the antenna port of the BS and the antenna port of a peripheral relay node do not overlap each other, the BS and relay node transmitting reference signals to a user equipment (UE) via the corresponding antenna ports that are mutually exclusively allocated and the BS receiving channel state information from the UE to obtain channel state information between the BS and the UE and channel state information between the relay node and the UE."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and apparatus for transmitting a reference signal in a relay communication system","description":"A method and apparatus for transmitting reference signals in a relay communication system are provided.
