Hybrid automatic repeat request transmission scheme with Chase combining (HARQ-CC) has been widely used to improve the throughput in wireless communication systems. However, for punctured polar codes, HARQ-CC cannot make up for the vacancies of the Log Likelihood Ratios (LLRs) of the punctured bits which are never transmitted at all, thus degrading the system efficiency. To address this issue, this paper proposes a new HARQ scheme based on the equivalent puncturing patterns (EPPs) of punctured polar codes. It successfully complements the LLRs of punctured bits, and therefore improves the system throughput. Moreover, we show that the proposed scheme can be implemented efficiently with the same complexity as HARQ-CC. Numerical results indicate that, for punctured polar codes with 21.875% puncturing proportion, the proposed HARQ achieves 7.5% improvement on the normalized system throughput compared with HARQ-CC. |
