Abstract

本发明实施例公开了一种功率控制方法、用户设备以及基站，能够在不同配比的载波聚合情况下进行功率控制。本发明实施例方法包括：用户设备UE接收基站发送的发射机功率控制TPC命令，所述TPC命令用于指示一个载波的功率调整值；若UE在所述一个载波的当前上行子帧的前一个上行子帧上未发送物理上行控制信道PUCCH，则UE根据该UE在多个载波中最近一次发送PUCCH时的PUCCH发射功率以及所述功率调整值进行TPC累积，得到更新后的所述一个载波的PUCCH发射功率，所述多个载波包括所述一个载波。本发明实施例还提供一种用户设备以及基站。本发明实施例能够在不同配比的载波聚合情况下进行功率控制。
