One embodiment according to the first aspect of the invention is there is provided one kind in a power control
The method that transmission power of the subscriber terminal equipment on a transmission channel on one-component carrier wave is controlled in control equipment.Subscriber terminal equipment can be accomplished in several ways, such as mobile phone or notebook computer.A variety of transmission channels, such as data channel can be included by sending channel（Such as PUSCH) or control channel（Such as PUCCH).
Reference picture 1, the method comprising the steps of 110, obtains first performance number, and first performance number is the candidate transmitting power that sends channel on of the subscriber terminal equipment on component carrier.
Candidate transmitting power of the subscriber terminal equipment on a transmission channel on one-component carrier wave can be obtained in several ways.In one embodiment, power control apparatus calculates the first performance number of a PUSCH channel on one-component carrier wave by formula 1.
S = min{Pc, formula 1
