A terminal apparatus that communicates with a base station apparatus, according to one embodiment of the present invention, receives information indicating a subframe in a first subframe set and a subframe in a second subframe set, using higher-layer signaling, calculates a power headroom using a first set of parameters and an estimated value of a downlink pathloss that is calculated in the terminal apparatus, if a certain subframe belongs to the first subframe set, to calculate the power headroom for the certain subframe, and calculates the power headroom using a second set of parameters and the estimated value of the downlink pathloss, if the certain subframe belongs to the second subframe set, in which a first parameter by which the estimated value of the downlink pathloss is multiplied is included in the first set of parameters, and a second parameter by which the estimated value of the downlink pathloss is multiplied is included in the second set of parameters. |
