There are two kinds of technique used for error control: FEC (Forward Error Correction) and ARQ (Automatic Repeat reQuest). Combining these two schemes, which is called HARQ (Hybrid ARQ), makes it possible to increase the channel throughput. The error of the channel quality estimate that is used to select the MCS (Modulation Coding Scheme) in type I HARQ can be a serious problem in scenarios when the mobile station moves at high speeds. Furthermore, in a system dominated by packet services, the interference level will be bursty and thus it is difficult to predict the interference level. Therefore, the type II HARQ scheme will be a more robust solution compared with type I HARQ scheme. In order to improve channel throughput while at the same time satisfying Quality of Service (QoS) under various channel conditions, an efficient hybrid ARQ type II scheme is proposed. In the proposed scheme, the optimum redundancy size for every transmission is calculated to maximize the throughput using QoS parameters, the performance of LDPC code and channel conditions. The proposed scheme, together with such benefits as QoS support, provides a way of achieving higher throughput in wireless communication systems.
