PROBLEM TO BE SOLVED: To enable appropriate setting of a modulation and coding scheme in the case where downlink multi-antenna transmission is applied.SOLUTION: A UE 100-1 transmits, to an eNB 200-1, null steering control information to direct null to the UE 100-1 at transmission from an eNB 200-2 to a UE 100-2 and first channel quality information on a modulation and coding scheme which is recommended if the null steering control information is employed by the eNB 200-2. The UE 100-1 performs control to transmit, to the eNB 200-1, second channel quality information on a modulation and coding scheme which is recommended if the null steering control information is not employed by the eNB 200-2, instead of the transmission of the first channel quality information or in addition to the transmission of the first channel quality information. |
