Abstract
The present invention relates to a method and apparatus for transmitting a channel measurement reference signal for measuring channel state from user equipment, and a method and apparatus for receiving the channel measurement reference signal. The base station of the present invention transmits power information concerning a plurality of nodes to user equipment capable of receiving signals from the plurality of nodes, and the plurality of nodes each transmit respective channel measurement reference signals. The power Information includes channel measurement reference signal, transmission power for each of the plurality of nodes and information indicating downlink data transmission power ratios. The user equipment calculates channel state information on the plurality of nodes based on the power Information and the channel measurement reference signals from the plurality of nodes.
