Abstract:
1. A method for determining uplink transmission power of a user equipment (UE) supporting carrier aggregation, the method comprising: receiving uplink scheduling information for performing uplink transmission in at least two serving cells from a base station; determining a first uplink maximum transmission power of each of the at least two serving cells; determining a second uplink maximum transmission power of the UE; and determining an uplink transmission power of each of the at least two serving cells based on the first uplink maximum transmission power of each of the at least two serving cells and the second uplink maximum transmission power of the UE, wherein a lower limit of the second uplink maximum transmission power is determined based on a maximum power reduction (MPR) parameter, an additive-maximum power reduction (A-MPR) parameter and a p-maximum power reduction (P-MPR).
