In this work an incremental redundancy hybrid automatic repeat request (H-ARQ) scheme, based on rateless coding, is introduced for future extensions of third generation mobile systems. The proposed solution is tested by simulating an UMTS terrestrial radio access network (UTRAN) long term evolution (LTE) cell environment and compared to the standardized hybrid ARQ scheme. Performance results are obtained in terms of average throughput and cumulative density functions (CDF) of the average delays. The main contributions of this work are a novel cell traffic simulation model for rateless coded transmissions and the application of such methods to UTRAN LTE hybrid ARQ systems.
