WIPO Patent Application WO/2010/123282
Kind Code:
A2
Abstract:
The present invention relates to a method and to an apparatus for transmitting reference signals in a relay communication system. The method for transmitting reference signals through a type 2 relay node in a relay communication system comprises: a step in which a base station allocates a plurality of antenna ports in a mutually exclusive manner so that the antenna port of the base station and the antenna port of the peripheral relay node do not overlap each other; a step in which the base station and the relay node transmit reference signals to user equipment through the respective antenna ports mutually exclusively allocated; and a step in which the base station receives channel state information from the user equipment to obtain channel state information between the base station and the user equipment and channel state information between the relay node and the user equipment.
