Hierarchical radio resource optimization for heterogeneous networks with enhanced inter-cell interference coordination (eICIC

by An Liu, Member Ieee, Vincent K. N. Lau, Fellow Ieee, Liangzhong Ruan, Junting Chen, Member Ieee - IEEE Trans. Signal Process , 2014
"... Abstract—Interference is a major performance bottleneck in Heterogeneous Network (HetNet) due to its multi-tier topological structure. We propose almost blank resource block (ABRB) for interference control in HetNet. When an ABRB is scheduled in a macro BS, a resource block (RB) with blank payload i ..."

is transmitted and this eliminates the interference from this macro BS to the pico BSs. We study a two timescale hierarchical radio resource management (RRM) scheme for HetNet with dynamic ABRB control. The long term controls, such as dynamic ABRB, are adaptive to the large scale fading at a RRM server for co

Game Theoretic Framework for Power Control in InterCell Interference Coordination

by unknown authors
"... monly identified as a key radio resource management mechanism to enhance system performance of 4G networks. This paper addresses the problem of ICIC in the downlink of cellular OFDMA systems where the power level selection process of resource blocks (RB) is apprehended as a sub-modular game. The exi ..."

interface in LTE (Long Term Evolution) networks [1], each BS will first select a pool of favorable RBs with low interference. Second, each BS will strive to fix the power level adequately on those selected RBs realizing performances comparable with the Max Power policy that uses full power on selected RBs

"... With the exponential growth in traffic demands during past years, Heterogeneous Networks (HetNets) are envisioned as the major capacity and performance enhancement enablers by means of increasing the spectral efficiency per unit area. Several multi-cell cooperation techniques have been developed in ..."

The main objective of this study is to analyze the performance of different
