TERMINAL DEVICE, BASE STATION DEVICE, COMMUNICATION METHOD, AND INTEGRATED CIRCUIT

摘要

In order to efficiently execute processing related to transmission power, provided is a terminal device provided with: a reception unit for receiving a first parameter and receiving a second parameter; and a first MAC processing unit for acquiring a Type 2 power headroom, wherein the first MAC processing unit obtains the value of the Type 2 power headroom for a primary cell if the first parameter is set and simultaneous communication using a physical uplink control channel (PUCCH) and a physical uplink shared channel (PUSCH) is set, and obtains the value of the Type 2 power headroom for the primary cell regardless of whether the simultaneous communication using the physical uplink control channel (PUCCH) and the physical uplink shared channel (PUSCH) is set if the second parameter is set.
