Japanese Patent JP5155431

B1

The addition and change of a CoMP transmission point performing a CoMP transmission/reception process is appropriately performed. A mobile communication method includes: a step of notifying, by a radio base station (eNB), configuration information of CSI-RS of a CoMP transmission point to a mobile station (UE) connected to a cell (#5) managed by the radio base station (eNB), when instructing an addition or change of the CoMP transmission point performing a CoMP transmission/reception process by "RRC Connection Reconfiguration"; a step of measuring, by the mobile station (UE), a CQI of the CoMP transmission point by using the CSI-RS of the CoMP transmission point, while performing the CoMP transmission/reception process; and a step of notifying, by the mobile station (UE), the CQI of the CoMP transmission point to the radio base station (eNB).
