Distributed Resource Allocation for Downlink Multicell OFDMA Systems
This paper addresses resource allocation for sum throughput maximization in a sectorized two-cell downlink OFDMA systems impaired by multicell interference. It is well known that the optimization problem for this scenario is NPhard and combinational, which is here converted to a novel sum throughput maximization problem based on the intercell interference limitation. Then, two subclasses of thi...
متن کاملResource Allocation in OFDMA Wireless Networks with Time-Varying Arrivals
This paper considers the issue of optimal subcarrier allocation in OFDMA wireless networks when the arrivals and channels are stochastic and time-varying. Our objective is to minimize the long-term average packet delay over multiple time epochs. We show by an example that water-filling-based subcarrier allocation policy which maximizes throughput at each time epoch is not optimal in this case. ...
متن کاملDistributed Assignment and Resource Allocation for Energy Efficiency in MIMO Wireless Networks
This paper deals with the problem of distributed resource allocation in multi-carrier MIMO networks, for energy efficiency maximization. The user-subcarrier assignment is jointly allocated together with the users’ transmit powers, subject to the constraint that each subcarrier can be used by only one user. To this end, a novel approach is proposed which merges the popular Dinkelbach’s algorithm...
متن کاملEfficient resource allocation for emerging OFDMA wireless networks
In the context of IEEE 802.16e networks, physical transmission relies on Orthogonal Frequency Division Multiple Access (OFDMA). This mechanism defines resource allocation as a bi-dimensional mapping of spectral resources. Although in the IEEE 802.16e standard the Medium Access Control (MAC) and physical (PHY) layers are well defined, the problem of resource allocation still remains an open issu...
متن کاملCooperative resource management and power allocation for multiuser OFDMA networks
Mobile network operators are facing the challenge to increase network capacity and satisfy the growth in data traffic demands. In this context, Long Term Evolution (LTE) networks, LTE-Advanced networks, and future mobile networks of the Fifth Generation seek to maximize spectrum profitability by choosing the frequency reuse-1 model. Due to this frequency usage model, advanced radio resource man...
