1. A terminal device that communicates with a base station device, comprising:

  • reception circuitry that receives first information related to a first configuration and/or second information related to a second configuration; and

    transmission circuitry that;

    transmits an uplink signal based on a first uplink power control in a first case where the first information related to the first configuration is received, and the second information related to the second configuration is not received, andtransmits the uplink signal based on a second uplink power control in a second case where the first information related to the first configuration and the second information related to the second configuration are both received, whereinthe first information related to the first configuration indicates a Time Division Duplex Uplink/Downlink (TDD UL/DL) configuration of uplink subframes for the uplink signal and downlink subframes for a downlink signal,the second information related to the second configuration is a bit map that indicates either one of a first subframe set and a second subframe set for each of the subframes,in the first uplink power control, the transmission circuitry determines a transmission power of the uplink signal based on a first power control parameter set, andin the second uplink power control, the transmission circuitry determines the transmission power on a first subframe of the first subframe set based on the first power control parameter set, and determines the transmission power on a second subframe of the second subframe set based on a second power control parameter set.
