Optimal Resource Allocation for IR-HARQ
2011 (English)In: Proceedings of the IEEE Swe-CTW, 2011, 74-79 p.Conference paper (Refereed)
In this work, we first provide an exact closed-form expression for the packet drop probability (PDP) in incremental redundancy (IR) based hybrid automatic repeat request (HARQ) schemes with a limit on the maximum number of transmissions. In the later part, we extend our work in , and consider the optimal resource allocation problem of minimizing the PDP under the constraints of an average transmit power and total number of channel uses. We provide two approaches to solve this optimization problem and compare their performance with the solution given in .
