摘要： A terminal includes a transmission unit which transmits HARQ response information to transmission of a downlink-shared channel in one or more predetermined subframes based on resources of one or more uplink control channels. When a certain subframe in the predetermined subframes is a first subframe, a resource of an uplink control channel is given by an arithmetic operation using at least an initial value of a control channel element for use in transmitting a physical downlink control channel in the certain subframe and a first value configured by a higher layer. When a certain subframe in the predetermined subframes is a second subframe, a resource of an uplink control channel is given by an arithmetic operation using at least an initial value of a control channel element for use in transmitting a physical downlink control channel in the certain subframe and a second value configured by a higher layer.

摘要： A terminal device that communicates with a base station apparatus includes a transmission unit that transmits a channel and/or a signal based on a maximum output power in a first cell group in a certain subframe. The maximum output power in the first cell group is a sum of a power that is determined based on uplink transmission in the first cell group in a certain subframe and a power that is allocated to the first cell group, of a residual power. The residual power is given by subtracting the power that is determined based on the uplink transmission in the first cell group in the certain subframe and a power for a second cell group from a sum of maximum output powers of the terminal device.

摘要： A terminal device that communicates with a base station apparatus includes a transmission unit that transmits a channel and/or a signal based on a maximum output power in a first cell group in a certain subframe. In a case where information relating to uplink transmission in the second cell group is recognized, a residual power is allocated based on a priority level of a type of uplink transmission. The residual power is given by subtracting a power that is determined based on uplink transmission in the first cell group and a power that is determined based on the uplink transmission in the second cell group from a sum of maximum output powers of the terminal device. The maximum output power is a sum of the power that is determined based on the uplink transmission in the first cell group and a power that is allocated to the first cell group, of the residual power.

摘要： A cell using an unallocated frequency band or a shared frequency band is efficiently controlled. A terminal device includes a reception unit configured to receive a first downlink physical channel mapped on the basis of a first possible starting position of a downlink transmission and a second downlink physical channel mapped on the basis of a second possible starting position of the downlink transmission. Upon the first possible starting position and the second possible starting position being indicated by a higher layer, the reception unit receives, in a predetermined subframe, either one of the first downlink physical channel or the second downlink physical channel, on a secondary cell having a frame structure type 3.

摘要： There is provided a terminal device capable of efficiently performing communication in a communication system in which a base station device and the terminal device communicate with each other. The terminal device that communicates with the base station device by using a plurality of aggregated cells recognizes that a serving cell is stopped in a first state, recognizes that the serving cell is started in a second state, and switches from the first state to the second state based on a received PDCCH.

摘要： To efficiently control a cell by using a non-allocated frequency band or a shared frequency band. A terminal device includes a transmission unit configured to transmit a PUSCH and a CCA check unit configured to perform LBT before a subframe for which a transmission of the PUSCH is indicated. The terminal device determines start time of the LBT, based on start time of the transmission of the PUSCH, a CCA slot length, and the number of CCA checks. The terminal device includes a reception unit configured to receive a PDCCH. The number of CCA checks is indicated on the PDCCH.

摘要： A terminal communicating with a base station by using FDD cells and TDD cells includes a reception unit that performs reception over a PDCCH transmitted using a DCI format. In a case where a primary cell is configured as the TDD cell for the terminal, DAI indicating the accumulated number of PDCCHs or EPDCCHs indicating releasing of downlink semi-persistent scheduling or transmission of a PDSCH in subframes until a current subframe of prescribed subframes is received while being included in the DCI format. A transmit power of a PUCCH transmitted while including HARQ-ACK corresponding to the PDCCH or the EPDCCH indicating the releasing of the downlink semi-persistent scheduling or the transmission of the PDSCH is determined based on a value of the DAI.
