论文摘要
与Hybrid自动重复请求相反，以增量冗余（HARQ-IR）的占用以重新发出冗余信息，交叉包HARQ（XP-HARQ）允许将新信息引入重新回归以实质性利用剩余资源。这封信对XP-HARQ的停电性能进行了深入的调查。特别是，如果最大传输数为两个，并且在两个以上的传输中获得了紧密的中断边界，则会得出XP-HARQ的确切中断表达。此外，在高信噪比（SNR）方面对XP-HARQ的渐近中断分析不仅是为了简化停电表达，还表明XP-HARQ可以实现全职多样性。最终提出了模拟结果以进行验证。
As opposed to hybrid automatic repeat request with incremental redundancy (HARQ-IR) that all the resources are occupied to resend the redundant information, cross-packet HARQ (XP-HARQ) allows the introduction of new information into retransmissions to substantially exploit the remaining resources. This letter provides a profound investigation into the outage performance of XP-HARQ. In particular, the exact outage expression of XP-HARQ is derived if the maximum number of transmissions is two, and tight outage bounds are obtained for more than two transmissions. Moreover, the asymptotic outage analysis of XP-HARQ in the high signal-to-noise ratio (SNR) regime is carried out not only to simplify the outage expression, but also to show that full time diversity is achievable by XP-HARQ. The simulation results are eventually presented for verifications.
