High data rate coded transmission concepts beyond 3G require development of efficient channel coding schemes suitable for packet data transmission. In this paper we suggest a hybrid ARQ (HARQ) scheme based on low complexity rate compatible punctured zigzag codes. In particular, we introduce a "virtual data reshaping" and present rate matching rules that practically do not suffer from sub-optimality due to puncturing. Furthermore, we introduce irregular PCZZ codes that allow to improve performance and coding rate flexibility of the PCZZ under the same rate matching framework.
