Abstract
The present invention relates to a method for configuring an acknowledgement mode of an HARQ re-transmission protocol used for acknowledging the delivery of data packets of a service provided from a transmitting entity to a receiving entity in a wireless communication system comprising a controlling entity in a radio access network. To improve the overall transmission efficiency while providing transmission robustness, the controlling entity configures, based on at least one of a QoS attribute or physical layer parameter, one of a first and second acknowledgement mode. An acknowledgement message is transmitted according to the configured acknowledgement mode, wherein, in case the data packet has not been decoded successfully by the receiving entity, the acknowledgement message in the first acknowledgement mode indicates one of a plurality of decoding quality levels of the data packet obtained when decoding the data packet at the receiving entity, and the acknowledgement message in the second acknowledgement mode indicates a decoding failure of the data packet.
