Joint eMBB-URLLC Resource Allocation Based on Reliability Requirements of Users

The emerging fifth generation of mobile communication (5G) systems is designed to cater to heterogeneous services. The enhanced mobile broadband (eMBB) services and ultra-reliable and low-latency communication (URLLC) services are two of the core services. These two types of heterogeneous services have different requirements for network throughput and delay. This paper studies the joint resource allocation of eMBB and URLLC services in the co-existence scenario to maximize the reliability of eMBB services and average data rate. We propose a heuristic eMBB resource allocation scheme. In the URLLC resource allocation phase, we employ the non-orthogonal multiple access (NOMA) superposition techniques to multiplex the transmitted eMBB services and use one-to-one matching theory to evaluate optimal eMBB and URLLC user pairs to protect low-rate, high service requirement of eMBB users. The simulation results prove our method scheme achieves better reliability and average data rate of eMBB services.
