Introduction to 4G Femtocells -- Ant Colony Algorithm (ACA) Based Downlink Resource Allocation in Femtocells -- Cross-Tier Interference Pricing Based Uplink Resource Allocation in Two-Tier Networks -- Resource Allocation in Femtocells with Cross-Tier Interference Limits -- Energy Efficient Power Control in Femtocells with Interference Pricing -- Differentiated-Pricing Based Power Allocation in Dense Femtocell Networks -- Conclusions and Future Works
Summary
This brief examines resource allocation and interference management for 4G femtocells. It introduces 4G femtocells in the context of 4G mobile networks and discusses related technical challenges in resource allocation and interference management. Topics include ant colony algorithm based downlink resource allocation, intelligent scheduling and power control, uplink and downlink for two-tier networks, quality of service (QoS) constraints and the cross-tier interference constraint. The authors present algorithms to alleviate common femtocell-related problems such as subchannel power allocation
