MOBILE COMMUNICATION METHOD

摘要

It is appropriately determined whether it is necessary for a radio base station to start a CoMP transmission/reception process based on the result of a quality measurement process during a CoMP transmission/reception process in a heterogeneous network environment. A mobile communication method according to the present invention includes a step in which, during "X2 Setup Procedure" between a radio base station (eNB #1) and a radio base station (eNB #2), the radio base station (eNB #1) transmits to the radio base station (eNB #2) an "X2 Setup Request" for giving notification of the PCI of neighbouring cells of the radio base station (eNB #1) and the CSI-RS used for a quality measurement process during the CoMP transmission/reception process in association with one another.
