Abstract:
1. A method of operating of a user equipment in a wireless communication system using a plurality of uplink frequencies, the method comprising the steps of: receiving grants for each of the plurality of uplink frequencies from a base station; dividing a maximum power of the user equipment for each of the plurality of uplink frequencies in accordance with the received grants for each of the received uplink frequencies, and selecting a corresponding transport block for each of the plurality of uplink frequencies by considering the received grants; and comparing a remaining power of the user equipment to a first subtraction power obtained by subtracting a power required to transmit a first transport block selected for a first uplink frequency from a power required to transmit a first minimum transport block, which transmits more data than those of the first transport block, wherein the remaining power of the user equipment is obtained by subtracting a power required to transmit the selected corresponding transport block for each of the plurality of uplink frequencies from the maximum power of the user equipment.
