摘要： A base station apparatus receives an uplink shared channel and a reference signal, the uplink shared channel including uplink data, an identifier of a terminal apparatus that has transmitted the uplink data, a first CRC generated from the identifier bits, and a second CRC generated from the uplink data bits. In a case that an error is detected based on the first CRC, the base station apparatus transmits a first NACK by using a control signal associated with the reference signal sequence. In a case that an error is detected based on the second CRC, the base station apparatus transmits a second NACK by using a control signal associated with the identifier indicating the terminal apparatus.

摘要： To improve throughput in a communication environment in which a large number of terminal apparatuses access, a receiver receives information indicating whether a radio resource allocated by a base station apparatus is a grant free access resource or a scheduled access resource, as well as transmission power control information in the scheduled access resource and transmission power control information in the grant free access resource; and a transmitter configured to transmit a transmission signal to the base station apparatus. In a case of communicating by using the scheduled access resource, a transmission power control is performed based on the first transmission power control information to transmit the transmission signal. In a case of communicating by using the grant-free access resource, the transmission power control is performed based on the second transmission power control information to transmit the transmission signal.

摘要： 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.
