Energy efficiency (EE) is becoming increasingly important for wireless cellular networks. This paper addresses EE optimization problems in downlink multiuser MIMO systems with linear precoding. Referring to different active transmit/receive antenna sets and transmission schemes as different modes, we propose a joint bandwidth/power optimization and mode(More)
—In this paper, we investigate the delay-aware dynamic resource management problem for multi-service transmission in high-speed railway wireless communications, with a focus on resource allocation among the services and power control along the time. By taking account of average delay requirements and power constraints, the considered problem is formulated(More)
Crosspoint buffered crossbar switches have gained much attention due to simple distributed scheduling algorithms. However, almost all the algorithms proposed for buffered crossbar switches either have unsatisfactory scheduling performance under non-uniform traffic or poor service fairness between input traffic flows. In order to overcome the disadvantages,(More)
