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.

Abstract: The present application relates to the field of wireless communications. Disclosed in an embodiment of the present application are a method and device for reporting power headroom (PH) under carrier aggregation, for solving the problem of how to report PH when a terminal supports the transmission of a physical uplink control channel (PUCCH) on different uplink carriers corresponding to different carrier groups. In the present application, a terminal generates a Type 1 PH and a Type 2 PH for each of multiple PUCCH-transmitting uplink carriers requiring PH reporting, generates a Type 1 PH for each non-PUCCH-transmitting uplink carrier requiring PH reporting, and reports each generated Type 1 PH and Type 2 PH to a network side in the current uplink subframe. The present application solves the above problem.

The method for a UE side thereof comprises: determining a TPC-RNTI corresponding to each carrier group and a tpc-index corresponding to each carrier group; detecting a PDCCH adopting a DCI format 3/3A and scrambled by using the TPC-RNTI corresponding to each carrier group in a common search space of a PCC; and according to the tpc-index corresponding to each carrier group, determining the position of an uplink power control command corresponding to the carrier group in the detected PDCCH scrambled by using the TPC-RNTI corresponding to the carrier group, and acquiring the uplink power control command corresponding to the carrier group from a corresponding position. Thus, a user equipment transmits a corresponding uplink power control command while supporting that uplink channels are transmitted over different uplink carriers corresponding to different carrier groups, thereby guaranteeing the normal and stable operation of a system.
