A method (1200, 2400) for wireless communication, comprising: establishing (1205, 2405), at a UE, a connection with a base station, the connection supporting two or more component carriers, CCs (205, 405, 410, 505, 510, 515); receiving (1210, 2410) a plurality of grants of uplink resources for a plurality of uplink transmissions (415, 420, 530, 535, 540, 545, 910, 915) on the two or more CCs (205, 405, 410, 505, 510, 515) during a slot (440, 550, 920), wherein the plurality of grants are received at least a predetermined time in advance of a start of the slot (440, 550, 920), wherein a transmit power to transmit the plurality of uplink transmissions exceeds a maximum power threshold for the UE during at least a portion of the slot (440, 550, 920); scaling (1225, 2415) a transmit power of at least a subset of the plurality of uplink transmissions to provide that the transmit power is less than or equal to the maximum power threshold; characterized in that the method further comprises: receiving an additional grant for an additional uplink transmission after the predetermined time and before the start of the slot (440, 550, 920); determining whether the total transmit power including a transmit power of the additional grant is greater than the maximum transmit power threshold for the UE during at least a portion of the slot (440, 550, 920); and dropping the additional uplink transmission responsive to determining that the additional uplink transmission would increase an aggregate transmit power of the UE above the maximum power threshold and transmitting (1235, 2420) the plurality of uplink transmissions (415, 420, 530, 535, 540, 545, 910, 915) during the slot (440, 550, 920) using one or more of the CCs (205, 405, 410, 505, 510, 515), or transmitting (1235, 2420) the additional uplink transmission and the plurality of uplink transmissions (415, 420, 530, 535, 540, 545, 910, 915) during the slot (440, 550, 920) using one or more of the CCs (205, 405, 410, 505, 510, 515) responsive to determining that the additional uplink transmission would not increase an aggregate transmit power of the UE over the maximum power threshold. establishing (1205, 2405), at a UE, a connection with a base station, the connection supporting two or more component carriers, CCs (205, 405, 410, 505, 510, 515);
