Dynamic Resource Scheduling Strategy with QoE-aware for the Coexistence of eMBB and URLLC Traffic

The coexistence of URLLC and eMBB services are very important for high data rate and low latency services in 5th Generation(5G) mobile network. But it is a difficult challenge to optimize resource allocation through effective scheduling in this case. Therefore, this paper proposes a coexistence scheme of URLLC and eMBB with the puncturing mechanism. Considering rate demands of different users, we introduce a QoE-aware utility function. Then, we formulate an optimization problem that maximize the average system utility while meeting URLLC requirements. Considering the non-deterministic polynomial(NP) hard nature of the problem, we divide the problem into two parts. In order to solve the problems, we take an iterative way, which further use an effective heuristic algorithm for resource allocation and URLLC puncturing. Simulation results show the advantage of this method compared with other ways.
