## Abstract

A method and apparatus provide a user equipment (UE) configured to communicate with a plurality of carrier aggregation (CA) groups with at least a first CA group (CG1) and a second CA group (CG2). The UE includes processing circuitry. The processing circuitry is configured to determine whether the UE is power-limited. The UE is scheduled to transmit acknowledged information in a physical uplink shared channel (PUSCH) to a cell of the CG1 and uplink control information (UCI), other than the acknowledgement information, in a physical uplink control channel (PUCCH) to a cell of the CG2. The processing circuitry is also configured to, responsive to the UE being power-limited, prioritize the PUSCH for power allocation. The processing circuitry is also configured to transmit the PUSCH to the cell of the CG1.
