Abstract

In future wireless communication area, a key issue is the resource allocation and scheduling over wireless channel. Various aspects of this issue have been studied. However, few studies are on the QoS guaranteed uplink multiple traffic scheduling in multi-user wireless network. The scheduling problem is addressed in this paper. We consider the TDM-OFDMA uplink multi-access queuing system with four types of traffic. Each type has specific QoS requirements, such as minimum rate, maximum latency and maximum jitter. This QoS guaranteed cross-layer scheduling issue is modeled as a convex optimization problem. We also prove our scheduling method can guarantee the minimum rate, maximum latency and maximum jitter asymptotically, meanwhile it also minimizes the residual integrated workload. According to the solvability of this optimization problem, we define the scheduling algorithm stability region, and design a heuristic algorithm for connection admission control. The numerical results show the substantial performance of the proposed algorithm.
