Abstract

By studying bandwidth allocation and puncture schemes, this paper intends to make a trade-off between QoS requirements of different services. For eMBB scheduling problem, we used proportional fairness algorithm (PF) as its resource scheduling algorithm, and then asked URLLC to perform puncture on the basis of eMBB scheduling results. Considering the case of URLLC overload, we set a rate loss threshold for eMBB users. When the eMBB rate loss reaches the threshold, the URLLC users in the current time slot will delay the transmission to the next mini-slot. In this paper, we propose a bandwidth allocation problem whose optimization objective is to minimize eMBB rate loss and URLLC transmission delay, and use matching theory to solve this problem.
