Abstract
- Ultra-reliable low-latency communication (uRLLC) and enhanced mobile broadband (eMBB) are two major service classes in the emerging 5G mobile network. uRLLC applications demand a stringent latency and reliability whereas eMBB services necessitate utmost data rates. The coexistence of uRLLC and eMBB services on the same radio resource leads to a challenging scheduling problem because of the trade-off among latency, reliability and spectral efficiency. In this paper, a puncturing scheme based coexistence approach between uRLLC and eMBB traffic is proposed for the upcoming 5G mobile networks. Specifically, an optimization problem is formulated with the objective of maximizing the minimum expected achieved rate of eMBB users in the long run basis while meeting the uRLLC requirements. To solve this co-scheduling optimization problem, we decomposed it into two sub-problems with the same objective of the original problem: 1) resource allocation problem for eMBB users, and 2) resource allocation problem for uRLLC users. A heuristic algorithm is used for solving the first sub-problem, whereas the one-sided matching game is used for solving the second. Simulation results show the advantages of the proposed approach over other baseline methods in terms of the minimum achieved rate and fairness among the eMBB users.
