Harq protocol with synchronous retransmissions

A method for transmitting data packets to a base station in a mobile wireless communication system comprising a mobile station and the base station using a HARQ retransmission protocol, the method comprising the following steps performed by the mobile terminal:

• transmitting a data packet to the base station,
• receiving a feedback message from the base station, wherein the feedback message indicates whether the data packet has been successfully decoded by the base station, and
• in case the feedback message indicates that the data packet has not been decoded successfully, transmitting a retransmission data packet after a predetermined time span upon having received the feedback message and optionally other data within the same transmission time interval using a maximum transmission power allowed to be used by the mobile terminal, if a transmission power required for transmitting the retransmission data packet and the other data is larger than the maximum allowed transmission power,
• wherein the other data has a higher logical channel priority than the data of the retransmission data packet.

A mobile station for transmitting data packets to a base station in a mobile wireless communication system comprising the mobile station and the base station using a HARQ retransmission protocol, the mobile station comprising:

• a transmitter operable to transmit a data packet to the base station, and
• a receiver operable to receive a feedback message from the base station, wherein the feedback message indicates whether the data packet has been successfully decoded by the base station,
• wherein, in case the feedback message indicates that the data packet has not been decoded successfully at the base station, the transmitter is operable to transmit a retransmission data packet after a predetermined time span upon having received the feedback message and optionally other data within the same transmission time interval using a maximum transmission power the mobile station is allowed to use, if a transmission power required for transmitting the retransmission data packet and the other data is larger than a maximum allowed transmission power,
• wherein the other data has a higher logical channel priority than the data of the retransmission data packet.
