An uplink transmission method, the method comprising:determining, by a user equipment (UE) configured with a first cell group of a first base station and a second cell group of a second base station, whether a first physical uplink control channel (PUCCH) transmission including a first scheduling request (SR) toward the first cell group is overlapped in a subframe with a second uplink channel transmission including a second SR toward the second cell group;
determining, by the UE, priorities of the first PUCCH transmission and the second uplink channel transmission when the overlap is determined in the subframe; and
performing, by the UE, both of the first PUCCH transmission including the first SR and the second uplink channel transmission including the second SR based on the determined priorities.
