摘要： A terminal includes: a control section that generates Capability information including UE Capability for a Power Class; and a transmission section that transmits the Capability information. The Power Class is specified by four items of Max Total Radiated Power (TRP), Max peak Equivalent Isotropic Radiated Power (EIRP), Min peak EIRP, and Spherical coverage EIRP, and an Inter-band-Carrier-Aggregation (CA) specified value of at least one of the Max peak EIRP and the Min peak EIRP for Inter-band CA in which a plurality of bands are used is defined by a method different from a method for a non-Inter-band-CA specified value.
