A communication method, said method being performed by a mobile station apparatus which is an apparatus within a mobile station, the communication method including: receiving, from a base station apparatus which is an apparatus within a base station providing a serving cell, a measurement configuration including a measurement object identifier identifying a measurement object, a report configuration identifier identifying a report configuration, and a measurement identifier associating the measurement object identifier and the report configuration identifier; wherein the measurement configuration further includes information regarding the reporting configuration identified by said reporting configuration identifier, said information comprising condition information indicating at least one of conditions to be judged by said mobile station apparatus to report measurement results using a type of reference signal called Channel State Information Reference Signal, CSI-RS; wherein the measurement configuration further includes information regarding the measurement object identified by said measurement object identifier, said information indicating a carrier frequency of the serving cell and one or more CSI-RS configurations, each of said one or more CSI-RS configurations containing a CSI-RS configuration identifier; and performing, in response to the measurement configuration, the steps of: measuring, for each one of said one or more CSI-RS configurations at the frequency indicated by said carrier frequency, a Reference Signal Received Power, RSRP, over a CSI-RS received from said base station apparatus as defined by said CSI-RS configuration; and judging, based on the one or more measured RSRPs, whether the condition defined by said condition information is complied with; measuring, at the frequency indicated by said carrier frequency, an RSRP of the serving cell over another type of reference signal called Cell-specific Reference Signal, CRS; and if the condition is complied with, transmitting a measurement report to the base station apparatus, said measurement report comprising measurement results, said measurement results including said measurement identifier, the RSRPs measured over CSI-RS and each RSRP together with its corresponding CSI-RS configuration identifier, along with the RSRP of the serving cell measured over CRS, regardless of the condition. receiving, from a base station apparatus which is an apparatus within a base station providing a serving cell, a measurement configuration including a measurement object identifier identifying a measurement object, a report configuration identifier identifying a report configuration, and a measurement identifier associating the measurement object identifier and the report configuration identifier;
