PROCESSING METHOD AND DEVICE FOR REDUCING UPLINK POWER, UE AND ENODEB THEREOF

摘要

A processing method and device for reducing uplink power, UE and an Evolved eNodeB are provided. The uplink power reduction processing method is applied to a scenario where a plurality of Uplink Control Information (UCI) are transmitted on different uplink Component Carriers (CCs) of the same subframe, and the method includes: it is determined that the sum of power of the uplink CCs exceeds a transmission power threshold of UE; and uplink power of the UE is reduced according to a preset power reduction rule. By the present invention, a problem about uplink power control for transmission of the plurality of UCI on different carriers of the same subframe is solved, and the effects of providing different protection for different data requirements and effectively controlling the uplink power are further achieved.
