摘要: 该文研究了在满足数据链路层中预先设定的延时和误包率限制的前提下，将递增冗余的type-II型HARQ应用于跨层设计的方法。推导出在Nakagami- 信道中，该方案的系统平均误包率和频谱利用率的数学表达式。得到结论：在跨层设计应用type-II型HARQ的误包率较低，频谱利用率较高，复杂度也较高；而type-I型HARQ反之。Abstract: The incremental redundancy type-II HARQ has been applied into the cross layer design. The closed-form expressions of the packet error rate and average spectral efficiency for the transmissions over Nakagami- channel have been derived. Numerical results show that the type-II HARQ with high complexity could achieve higher spectral efficiency and lower packet error rate compared with the cross layer design system with type-I HARQ. While the type-I HARQ has the lower spectral efficiency and the higher packet error rate, but its complexity is low.
