Radio base station apparatus, mobile terminal apparatus, radio communication method and radio communication system

A mobile terminal apparatus comprising:

• a reception section that receives information for demodulation of a data signal from a serving cell in applying Coordinated Multi-Point transmission;
• and
• a demodulation section that demodulates the data signal subjected to Coordinated Multi-Point reception using the information for demodulation.

A radio communication system comprising:

• a radio base station apparatus having a generation section that generates information for demodulation of a data signal in a mobile terminal apparatus in applying Coordinated Multi-Point transmission, and a transmission section that transmits the information for demodulation to a mobile terminal apparatus that performs Coordinated Multi-Point reception;
• and
• a mobile terminal apparatus having a reception section that receives the information for demodulation of a data signal, and a demodulation section that demodulates the data signal subjected to Coordinated Multi-Point reception using the information for demodulation.
