Patent ID: 7509554

Claim:
A method for transmitting uplink data packets via an uplink data channel to a base station in a mobile wireless communication system comprising a mobile station and the base station using a hybrid automatic repeat request (HARQ) retransmission protocol applying soft combining of data packets and applying synchronous retransmissions, the method comprising the following steps performed by the mobile station: transmitting a data packet to the base station via the uplink data channel, receiving a feedback message from the base station, wherein the feedback message indicates that the data packet has not been successfully decoded by the base station, and determining whether the transmission power required for synchronously transmitting a retransmission data packet for the unsuccessfully decoded data packet at a predetermined point in time after having received the feedback message and for transmitting other uplink data within the same transmission time interval is lower than a maximum allowed transmission that the mobile station is allowed to utilize for transmitting uplink data, wherein the other uplink data is prioritized over the retransmission data packet; and synchronously transmitting the retransmission data packet at the predetermined point in time and transmitting the other data using the maximum allowed transmission power, if the required transmission power is larger than the maximum allowed transmission power.
