N2 - Ultra-reliable and low-latency (UR-LL) communications are considered as a key feature in many application scenarios. Particularly, the 5th generation (5G) cellular networks are the main candidate for the implementation of UR-LL communications, by exploiting short packet transmissions. On the other hand, energy-harvesting (EH) solutions are envisaged to provide sustainable and self-sufficient green networks. In this paper, the tradeoffs between reliability and packet latency in a multi-user random access UR-LL-EH-5G network with finite blocklength codes is studied, while incorporating energy- and data-causality constraints. Analytical derivations for reliability and packet latency are provided to investigate the effect of diversity transmission, and the number of resource blocks allocated to user equipments (UEs). The derived analytical expressions are then numerically evaluated to shed light on different tradeoffs.
