摘要:
Provided are a wireless communication terminal device and a power allocation method, wherein transmission channel quality information, regarding a Pcell having a high probability that UCI is multiplied therein, can be accurately estimated by an SRS having high priority in power allocation, and an eNB can instruct appropriate transmission power to an UL channel which transmits the subsequent UCI. A power scaling detection unit (108) detects whether or not a total transmission power value of the UL channels transmitted by the plurality of CC exceeds the maximum transmission power specific to the UE. When a plurality of SRS are simultaneously transmitted using a Pcell and a Scell, and power scaling occurs, a power scaling control unit (109) performs power allocation so that transmission power of the SRS of the Pcell has the higher priority than that of the SRS of the Scell.
