On Scheduling and Interference Coordination Policies for Multicell OFDMA Networks
In orthogonal frequency division multiple access systems there is an intimate relationship between the packet scheduler and the inter-cell interference coordination (ICIC) functionalities: they determine the set of frequency channels (sub-carriers) that are used to carry the packets of in-progress sessions. In this paper we build on previous work in which we compared the so called random and co...
متن کاملScheduling Constraints and Interference Graph Properties for Graph-based Interference Coordination in Cellular OFDMA Networks
The currently emerging 802.16e (WiMAX) and 3GPP Long Term Evolution (LTE) cellular systems are based on Orthogonal Frequency Division Multiple Access (OFDMA). OFDMA suffers from heavy inter-cell interference if neighboring base stations use the same frequency range. One approach to solve this issue is the application of beamforming antennas in combination with interference coordination (IFCO) m...
متن کاملRobust Multicell Cooperation in MIMO-OFDMA Networks
In future communication systems, the constraint of resource allocation is a challenging topic. The cell edge users in wireless systems experience low Signal to Interference and Noise Ratio (SINR) due to the high InterCell Interference (ICI) and cannot fully benefit from Multiple-Input Multiple-Output (MIMO) multi-stream transmission capability. In this project, a practical approach to the multi...
متن کاملDynamic fractional frequency reuse (D-FFR) for multicell OFDMA networks using a graph framework
A graph-based framework is proposed in this paper to implement dynamic fractional frequency reuse (D-FFR) in a multicell Orthogonal Frequency Division Multiple Access (OFDMA) network. FFR is a promising resource-allocation technique that can effectively mitigate intercell interference (ICI) in OFDMA networks. The proposed D-FFR scheme enhances the conventional FFR by enabling adaptive spectral ...
