Spectrum Allocation Strategies for Heterogeneous Networks [PDF]
Proceedings of the 6th International ICST Conference on Cognitive Radio Oriented Wireless Networks and Communications, 2011 This work analyzed the trade-off between the area spectral efficiency and outage user rates in heterogeneous cellular networks with overlapping picocells. We considered two different models for the spectrum allocation and cell association. The first model employs a spectrum overlapping strategy with an SINR-based cell association.

On the Efficiency and Complexity of Distributed Spectrum Allocation [PDF]
2007 2nd International Conference on Cognitive Radio Oriented Wireless Networks and Communications, 2007 We study the efficiency and complexity of a distributed spectrum allocation algorithm using explicit user coordination. Users self-organize into coordination groups and adjust spectrum assignments in each local group to approximate an optimal assignment.

Downlink spectrum allocation in 5G HetNets [PDF]
2014 International Wireless Communications and Mobile Computing Conference (IWCMC), 2014 Fifth generation mobile systems (5G) target an Average Area Spectral Efficiency (AASE) over hundred Gbps/km/user for future mobile systems with an Energy Dissipation (ED) per unit area similar to the current ED levels. Heterogeneous networks (HetNets) with high density of deployed small cells are currently adopted to aid in achieving the target ED and ...
