论文摘要
我们研究了构成宏基站（MBSS），小型基站（SBSS）和移动用户的超密集网络（UDN）中延迟效率和可靠数据传递的问题。考虑到两跳数据传输系统，我们提出了部分解码和前向（PDF）中继策略以及对无重量代码的简单且直观的友好编码方案，以在端到端延迟方面显着提高用户体验。仿真结果验证了我们的友好编码方案在改善无重量代码的中间性能方面有效。它还验证了我们提出的PDF是否显着提高了解码和前向（DF）策略的性能，并且PDF在渠道降解方面更加强大。总体而言，在UDN方案中，提出的策略和编码方案在延迟敏感的数据传递方面有效。
We investigate the problem of delay-efficient and reliable data delivery in ultra-dense networks (UDNs) that constitute macro base stations (MBSs), small base stations (SBSs), and mobile users. Considering a two-hop data delivery system, we propose a partial decode-and-forward (PDF) relaying strategy together with a simple and intuitive amicable encoding scheme for rateless codes to significantly improve user experience in terms of end-to-end delay. Simulation results verify that our amicable encoding scheme is efficient in improving the intermediate performance of rateless codes. It also verifies that our proposed PDF significantly improves the performance of the decode-and-forward (DF) strategy, and that PDF is much more robust against channel degradation. Overall, the proposed strategy and encoding scheme are efficient towards delay-sensitive data delivery in the UDN scenarios.
