Existing downlink multiplexing mechanisms include resource reservation and puncture preemption with different characteristics and performance. A fuzzy logic based multiplexing mechanism selection algorithm is proposed to make optimal selections between resource reservation and puncture preemption according to the characteristics of URLLC services. The algorithm improves the system performance by combining the advantages of the two mechanisms. Simulations show that the queueing delay of URLLC services is reduced by nearly 50% after the optimal selection. At the same time, the reduction in throughput of eMBB services caused by URLLC services is less than 4%. %U https://journal.bupt.edu.cn/EN/10.13190/j.jbupt.2020-231
