论文摘要
智能反射表面（IRS）是一种扩展无线覆盖范围的新兴技术。在这封信中，分析了IRS辅助系统的混合自动重复请求（Hybrid-ARQ）的性能。更具体地说，研究了使用Chase组合的混合ARQ协议的IRS ADED系统的中断性能。渐近分析还表明，通过增加IRS辅助系统的反射器数量，中断性能比线性地提高了。结果还验证了将ARQ方案组合在IRS ADED系统的链路层中的潜力，并证明路径损失条件的很小变化可能会影响性能。
The intelligent reflecting surface (IRS) is an emerging technique to extend the wireless coverage. In this letter, the performance of hybrid automatic repeat request (hybrid-ARQ) for an IRS-assisted system is analyzed. More specifically, the outage performance of the IRS-aided system using hybrid-ARQ protocol with chase combining is studied. Asymptotic analysis also shows that the outage performance improves better than linearly by increasing number of reflectors of the IRS-aided system. The results also verify the potential of combining the ARQ scheme in the link layer of the IRS-aided system and demonstrate that very small change of path loss condition can impact the performance largely.
