PROBLEM TO BE SOLVED: To provide a mobile station and a CSI report method capable of promptly changing a reporting setting in a system which performs CoMP transmission.SOLUTION: A mobile station receives a first signal of RRC signaling which includes a first identifier related to a first CSI-RS resource or a second identifier related to a second CSI-RS resource, and also receives a second signal in a PDCCH which includes at least one of a first value corresponding to the first identifier and a second value corresponding to the second identifier. When the second signal includes the first value, the mobile station executes first channel measurement for a first CQI value on the basis of a first CSI-RS in the first CSI-RS resource, whereas when the second signal includes the second value, the mobile station executes the first channel measurement for the first CQI value on the basis of a second CSI-RS in the second CSI-RS resource, to report CSI including the first CQI value.SELECTED DRAWING: Figure 4 |
