    Abstract: Optimal transmit power control is performed in a band other than licensed bands. When the way of specifying transmit power differs between the licensed band and a frequency band other than the licensed band, the expression of the transmit power control is changed to perform transmit power control. A terminal apparatus includes a carrier aggregation radio transmission unit configured to simultaneously transmit a plurality of component carriers, and a transmit power control unit configured to control transmit power of each of the plurality of component carriers, wherein the transmit power control unit calculates a transmit power of a dedicatedly usable first component carrier among the plurality of component carriers in consideration of the transmit power of the first component carrier, and calculates a transmit power of a second component carrier other than the dedicatedly usable first component carrier in consideration of the transmit power of the first component carrier.

    Abstract: When an unlicensed band is used, a more efficient control is provided, and a communication is established, or ensured and continues by stably using the unlicensed band. According to the present invention, there is provided a base station apparatus which applies a communication scheme applied to a frequency band allowed to be dedicatedly used, to a frequency band of which dedicated use is not allowed, and enables a communicate with a terminal device by using the frequency band of which dedicated use is not allowed, along with the frequency band allowed to be dedicatedly used. In a state where the frequency band of which dedicated use is not allowed is not used for a communication with the terminal device, to which the communication scheme is applied, the terminal device is notified of control information, and thus the communication scheme is applied to the frequency band of which dedicated use is not allowed, and the terminal device is instructed to communicate with the base station apparatus. The control information is required for a control when the frequency band of which dedicated use is not allowed is used in a communication with the terminal device, to which the communication scheme is applied.

    Abstract: Selection of a suitable MCS improves throughput without increasing the number of pieces of control information. With RRC signaling, information on PDCCH and a CQI table that is referred to are associated with each other, and the CQI table that is referred to is determined based on information relating to the PDCCH. Thus, the CQI table that is referred to is selected at high speed. Furthermore, information relating to control information is control information that is included in the PDCCH or an ePDCCH. Furthermore, the information relating to the control information is a type of search space of the PDCCH or the ePDCCH.

    Abstract: In M2M communication, data transmission is performed 4 msec after control information for dynamic scheduling is received from a base station apparatus, and the data transmission that needs immediacy has more overhead. In a case where a transmission apparatus performs data transmission to a reception apparatus, there are a first transmission mode in which a data signal based on a transmission parameter included in the received control information is transmitted, and a second transmission mode in which the control signal information is not received, and the data signal is transmitted without the reception apparatus being notified of a transmission timing of the data signal. In a case where transmission of an SR is possible and in a case where data communication is possible with the first transmission mode and the second transmission mode, the transmission apparatus configures different transmission powers in accordance with the transmission modes.
