We consider a scheduled orthogonal frequency division multiplexed (OFDM) wireless
cellular network where the channels from the base-station to the n mobile users undergo flat …

This paper considers the problem of minimizing outage probabilities in the downlink of a
multiuser, multicell orthogonal frequency division multiple access (OFDMA) cellular network …

We propose a four-stage hierarchical resource allocation scheme for the downlink of a large-
scale small-cell network in the context of orthogonal frequency-division multiple access …

We consider use of fixed broadband wireless networks to provide packet services for
telecommuting and Internet access. Each cell is divided into multiple sectors, each of them …

In wireless cellular networks and wireless local area networks, nonlinear network utility
maximization need to be conducted over both user rates and transmit powers. For each of …

In this paper, we provide a theoretical framework for cross-layer optimization for orthogonal
frequency division multiplexing (OFDM) wireless networks. The utility is used in our study to …

In this work, we develop mathematical and algorithmic tools for distributed resource
allocation in downlink of mobile cellular networks. Our algorithms perform power allocation …

In most of researches in resource allocation for wireless networks, uplink and downlink
problems are considered separately, especially when resources for uplink and downlink are …

In this paper, we develop an energy-efficient resource-allocation scheme with proportional
fairness for downlink multiuser orthogonal frequency-division multiplexing (OFDM) systems …

Joint channel and rate allocation with power minimization in orthogonal frequency-division
multiple access (OFDMA) has attracted extensive attention. Most of the research has dealt …
