The present disclosure provides a power control method and a power control apparatus for uplink channels. The power control method includes steps of: determining, by a UE, target transmission powers for the uplink channels in each carrier group, the UE being configured with at least two carrier groups, UCI in each carrier group being fed back via PUCCH(s) and/or PUSCH(s) on at least one uplink carrier corresponding to the carrier group; determining, by the UE, whether or not a sum of the target transmission powers for the simultaneous transmission uplink channels exceeds an allowable maximum transmission power of the UE; and in the case that the sum of the target transmission powers for the simultaneous transmission uplink channels exceeds the allowable maximum transmission power of the UE, reducing, by the UE, powers for the PUCCH(s) and/or PUSCH(s) carrying the UCI of different carrier groups among the simultaneous transmission uplink channels at least in accordance with priorities of types of the UCI, so that a sum of the transmission powers for all the uplink channels in a current uplink subframe does not exceed the allowable maximum transmission power of the UE. According to the present disclosure, it is able to perform uplink power control in the case that the UE supports the independent UCI feedback for different carrier groups. |
