摘要： Provided is a wireless communication terminal which, when SRSs are simultaneously transmitted between CCs and between antenna ports, avoids increasing the effect of bit rounding errors of D/A converters when the number of antenna ports set for SRS transmission differs between CCs. This device comprises a transmission power calculation unit (107) which calculates the transmission power of a plurality of UL channels of a plurality of CCs and a plurality of antenna ports. A power scaling detection unit (108) detects whether or not the total transmission power of the UL channels exceeds the maximum transmission power specific to a UE. When power scaling is generated, a power scaling control unit (109) uses antenna port setting information set for SRS transmission between CCs to perform power scaling in such a way that all scaling weights are uniform between CCs, or between CCs and between antenna ports.

摘要： A wireless communication mobile station apparatus wherein the accuracy of measuring the communication quality can be improved. In this apparatus, a desired signal power measuring part (212) uses a reference signal received from a local-cell reference signal processing part (211) to measure the power of a desired signal addressed to the local apparatus. An interference signal power measuring part (214) uses a reference signal received from an other-cell reference signal processing part (213) to measure an other-cell interference signal power removable by retransmission. An interference power calculating part (215) then uses a reference signal received from the separating part (203), the desired signal power received from the desired signal power measuring part (212) and the removable-by-retransmission other-cell interference signal power received from the interference signal power measuring part (214) to calculate an interference power that is a sum of the removable-by-retransmission other-cell interference signal power and the noise power. A communication quality generating part (216) then uses the desired signal power (S) and the sum of the removable-by-retransmission other-cell interference signal power and the noise power to generate communication quality information of the signal addressed to the local apparatus.

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.
