摘要：

In this paper, we present the optimization of the packet loss probability in distributed antenna system (DAS) to enable the downlink ultra-reliable and low-latency communication (DL URLLC) for the industrial IoT. To satisfy the low-latency, the short packet length is exploited and accordingly, the achievable rate under the finite blocklength codes is considered in the analysis of the packet loss probability of DAS for DL URLLC. Specifically, the packet loss probability is approximated as the sum of the channel outage probability (OP) and the finite blocklength coding error probability. Note that the channel OP is a function of the coding error probability due to short packet length. Accordingly, when the sensor nodes and the DA ports are randomly distributed in a given area, we optimize the short blocklength coding error probability to minimize the overall packet loss probability.
