摘要： A method, system and device for determining the priority of a component carrier are disclosed. The method includes: a network control unit and/or a terminal determining the priority of the component carrier according to carrier information about the component carrier. This method, system and device can enable the UE to rapidly select a downlink carrier when the periodic CQI/PMI/RI feedback with respect to the downlink carrier conflict and the UE can be notified with no need of additional signaling or only by using the reserved bit or only by way of a little high layer signaling overhead, the implementation of which is convenient.

摘要： The present disclosure provides a method for reducing the transmission power of an uplink signal, comprising: performing, by a User Equipment (UE), Component Carrier (CC) grouping on configured uplink CCs; and comparing correspondingly the transmission power of an uplink signal in each CC group with a maximum transmission power configured for the each CC group by an evolved Node B (eNB), and performing a power reduction within the CC group when the comparison result meets an intra-group power reduction condition; and/or comparing the sum of transmission powers of uplink signals in all CC groups with a maximum transmission power configured for the UE by the eNB, when the comparison result meets an inter-group power reduction condition, performing a power reduction between the CC groups. The present disclosure further provides a device for reducing the transmission power of an uplink signal. The technical solution of the present disclosure can improve the covering capability and reliability of the uplink signal in an Inter-band CA scenario, and to improve a utilization rate of a UE's uplink transmission power.
