Extended repeat request scheme for mobile communication networks

摘要

The present invention provides a method of optimizing repeat request cycles between transmitter and receiver of a wireless communication network as well as a base station and a mobile station that are adapted to execute the inventive method. A first data packet that is transmitted from a base station to a mobile station is stored preferably by means of a softbuffer module and becomes subject to a decoding procedure. In case of failure the failed decoding procedure is further analyzed preferably in combination with the status of the softbuffer module. In this way information is generated that is indicative of a reason of failure and that allows to specify a different portion and/or different redundancy version for the transmission of a subsequent data packet. Preferably, the mobile station itself specifies a required type of data or a required type of redundancy version that is needed for a sufficient decoding and/or recovering of transmitted data by means of the mobile station. Hence, a retransmission can be entirely determined by the mobile station by effectively exploiting information that has been obtained from previous data packet transmissions.
