We study a stochastic network that consists of two servers shared by two classes of jobs. Class 1 jobs require a concurrent occupancy of both servers while class 2 jobs use one se...
— We address the problem of radio resource allocation in the Downlink (DL) of relay–aided cellular system, based on OFDMA transmission technology. There has been little work on...
— We address the problem of radio resource allocation in the Downlink (DL) of a cellular system with Relay Stations (RS), based on Orthogonal Frequency Division Multiple Access (...
—Hierarchical cellular networks (HCNs), in which femtocells are deployed in the coverage of a conventional macrocell, offer a cost effective solution to achieve high user capacit...
— In this paper, we study the joint design of uplink and downlink resources in OFDMA-based systems. We first analyze the interactions between uplink and downlink, due essentiall...
