Patent ID: 8687541

Claim:
A method for controlling transmit powers for transmissions of transport blocks on uplink component carriers of a mobile communication system in a power limited situation, the method comprising the following steps performed by a mobile terminal: receiving uplink resource assignments that schedule transmissions of the transport blocks on the uplink component carriers within a transmission time interval, wherein the uplink resource assignments have a priority order, determining for each transmission of a respective one of the transport blocks, a transmit power required for transmitting the respective transport block according to its corresponding uplink resource assignment, reducing the determined transmit power for each transmission of a respective one of the transport blocks according to the priority of the transport block given by the priority orders, wherein the lower the priority of an uplink resource assignment, the larger the power reduction applied to the transmit power for the transmission of the transport block required by its corresponding uplink resource assignment, and the higher the priority of an uplink resource assignment, the smaller the power reduction applied to the transmit power for the transmission of the transport block required by its corresponding uplink resource assignment, and transmitting the transport blocks on the uplink component carriers within the transmission time interval, wherein each transport block is transmitted using the reduced transmit power.
