Communication system, terminal, and base station

A terminal for communicating with a base station, comprising:

• a transmitting unit configured to report a channel state to the base station on the basis of a first reference signal configuration configured by the base station;
• a terminal receiving unit configured to determine a resource element to be excluded from the target of data demodulation in a case where data is demodulated, on the basis of a second reference signal configuration configured by the base station, to demodulate data;
• and
• a channel measurement unit configured to measure a reference signal received power on the basis of a third reference signal configuration configured by the base station.

A base station for communicating with a terminal, comprising:

• a base station receiving unit configured to configure a first reference signal configuration for each terminal, and to receive a channel state report on the basis of the first reference signal configuration;
• a radio resource control unit configured to configure a second reference signal configuration for each terminal, and to specify a resource element to be excluded from the target of data demodulation in a case where the terminal demodulates data, on the basis of the second reference signal configuration;
• and
• a higher layer processing unit configured to configure a third reference signal configuration for each terminal, and to given an instruction to measure a reference signal received power on the basis of the second reference signal configuration.
