Abstract
The present invention is designed to provide a wireless communication system a base station apparatus a user terminal and a channel state information measurement method that can allow a user terminal to feed back channel quality information that is optimal for a transmission mode from a plurality of transmission points. A wireless communication system according to the present invention provides a base station apparatus having a determining section that determines resource information about resources to allocate the reference signal for measuring desired signals to and resource for measuring interference signals and a reporting section that reports the resource information to the user terminal and the user terminal having a receiving section that receives the reported resource information a measurement section that measures desired signals and interference signals based on the resource information and a measurement section that measures the channel state using the measurement results of the measurement section.
