Claim of US Patent No. 10,893,480

1. A terminal device comprising:a transceiver configured to perform wireless communication; and
a controller configured to allocate power for communication between a first serving cell and a second serving cell with different sub frame lengths,
wherein the controller
calculates transmission power of a first uplink physical channel occurring in the first serving cell in a first time unit, and
calculates transmission power of a second uplink physical channel occurring in the second serving cell in a second time unit,
wherein the first uplink physical channel overlaps with the second uplink physical channel on a time axis, and
wherein when a sum of transmission power required by the first uplink physical channel and transmission power required by the second uplink physical channel exceeds a maximum uplink power, allocate the transmission power of the first uplink physical channel and the transmission power of the second uplink physical channel so as to not exceed maximum uplink transmission power in all sections of the first time unit and the second time unit.
