1. A terminal device that communicates with a base station device by using a plurality of serving cells including a primary cell (Pcell) and a secondary cell (Scell), the terminal device comprising:
receiving circuitry configured to
receive a first parameter used for indicating that a power headroom is to be reported using a first medium access control (MAC) control element, and
receive a second parameter used for indicating that simultaneous transmission of a physical uplink control channel (PUCCH) and a physical uplink shared channel (PUSCH) is configured, the second parameter being different from the first parameter; and
MAC processing circuitry configured to obtain a value of Type 2 power headroom, wherein
the MAC processing circuitry is configured to
obtain the value of Type 2 power headroom for the Scell configured with the PUCCH in a case that the first parameter is configured, the Scell is configured with the PUCCH, and the Scell configured with the PUCCH is activated, and
obtain the value of Type 2 power headroom for the Pcell in a case that the first parameter is configured, the Scell is not configured with the PUCCH, and the second parameter is configured for the Pcell.
