Abstract
A method for uplink transmission in a wireless communication system, the method includes determining, by a user equipment (UE), whether the first uplink signal to be transmitted toward a first cell belonging to a first timing advance group (TAG) at an nth subframe overlaps the second uplink signal to be transmitted toward a second cell belonging to a second TAG at an (n+1)st subframe; dropping, by the UE, the first uplink signal at the nth subframe, if a total transmission power including the first and second uplink signals exceeds a maximum transmit power, where n is an integer≥1; and transmitting the second uplink signal without the first uplink signal which is dropped.
