1. A method for managing transmission power control by a user equipment (UE) in a carrier aggregation based wireless communication system, the method comprising:

  • transmitting a first physical uplink control channel (PUCCH), including first uplink control information (UCI), via a first cell of a first cell group, the first UCI being a first type UCI having a first UCI priority; and

    transmitting a second PUCCH, including a second UCI, via a second cell of a second cell group, the second UCI being a second type UCI having a second UCI priority,wherein a first transmission power is allocated to the first PUCCH and a second transmission power is allocated to the second PUCCH according to a power allocation rule so that a total transmit power limit of the UE is not exceeded, andwherein the first cell group comprises a primary cell (PCell) and zero or more secondary cells (SCells), and the second cell group comprises one or more SCells,wherein the power allocation rule includes;

    preferentially allocating power to the first transmission power when the first priority is higher than the second priority, and preferentially allocating power to the second transmission power when the second priority is higher than the first priority, andpreferentially allocating power to the first transmission power when the first priority is equal to the second priority and the first PUCCH is transmitted on the PCell of the first cell group.
