Abstract: A base station apparatus, a terminal apparatus, and a communication method are provided in which reliability, frequency efficiency, or throughput can be improved in a case that transmission is performed based on beam forming. For a first CRI indicating a first CSI-RS resource and a second CRI indicating a second CSI-RS resource, the first and second CRIs being simultaneously receivable by the terminal apparatus, a first RI for the first CRI and a second RI for the second CRI are determined, and in a case that a total of the first RI and the second RI is four or less, a CQI determined by using both the first CRI and the second CRI is determined, and in a case that the total of the first RI and the second RI is greater than four, a first CQI determined by using the first CRI and a second CQI determined by using the second CRI are determined.

Abstract: The present invention relates to a base station apparatus, a terminal apparatus, and a communication method. In a case that Multi-User Superposition Transmission (MUST) is applied, the transmit power for applying 256 QAM is insufficient. MUST is efficiently applied in an environment in which an MCS table including 256 QAM is configured for use. The base station includes an MCS configuration unit configured to hold a first table including MCS indices that include 256 QAM, and a second table not including 256 QAM, and in a case of performing MUST, configure an MCS not including 256QAM for downlink data of the second terminal, and a PDSCH generating unit configured to generate, by use of MUST, downlink data of the first terminal and downlink data of the second terminal that are generated based on the MCS indices configured.
