Wireless base station device, mobile terminal device, wireless communication method, and wireless communication system

摘要

The present invention accurately demodulates a data signal in a mobile terminal device during a coordinated multipoint (CoMP) transmission, especially during a joint processing coordinated multipoint (JP-CoMP) transmission. The wireless communication method of the present invention is characterized in that a wireless base station device generates a set of demodulation information of the data signal in a mobile terminal device during a coordinated multipoint transmission and transmits the demodulation information to a mobile terminal device which receives via coordinated multipoint reception, and in that a mobile terminal device receives the demodulation information of the data signal and demodulates the data signal that was received via coordinated multipoint reception by using the demodulation information.
