Ultra-reliable and low-latency communication (URLLC) is one of the key technologies to achieve "Industry 4.0", but nowadays a comprehensive understanding of the fundamental performance limit and optimal design principles for such systems is lacking. In light of the inability of the conventional Shannon capacity formula for characterizing ultra low-latency transmissions, this proposal aims at studying fundamental questions of URLLC based systems on the recently proposed capacity formula of finite blocklength codes. Three research subjects will be considered, including 1) Achievable performance limits of URLLC systems, 2) Optimal resource allocation for URLLC systems, and 3) Energy management in energy harvesting URLLC systems. The proposal will deliver important results such as the tradeoff between transmission rate, reliability, delay and energy, optimal frame structure design, channel feedback design, and energy efficient resource allocation algorithms for massive access. The proposal aims at fundamentally promoting both research and applications of URLLC.

超可靠低延迟通信（URLLC）是实现“工业4.0”的关键技术之一，但目前对此类系统的基本性能限制和优化设计原则缺乏全面的了解。鉴于传统的香农容量公式表征超低延迟传输的能力不足，本建议旨在研究基于URLLC的系统的基本问题，最近提出的有限块长码的容量公式。三个研究主题将被考虑，包括1）可扩展的性能限制的URLLC系统，2）最佳资源分配URLLC系统，和3）能量收集URLLC系统中的能量管理。该建议将提供重要的结果，如传输速率，可靠性，延迟和能量之间的权衡，最佳帧结构设计，信道反馈设计，和能量有效的资源分配算法的大规模访问。 该建议旨在从根本上促进URLLC的研究和应用。
