Resource allocation for relay-assisted OFDMA systems using inter-cell interference coordination
This article proposes a new enhanced fractional frequency reuse (FFR) scheme to improve the system performance in multi-cell orthogonal frequency division multiple access system, which tackles the problems of frequency distribution and inter-cell interference (ICI) by jointly FFR and ICI coordination. The proposed scheme dynamically assigns subcarriers to center and edge groups depending on loa...
متن کاملResource Allocation for OFDMA Relay Networks with Inter-Cell Interference Coordination
In this paper, a resource allocation algorithm is proposed for OFDMA relay networks with inter-cell interference coordination. Simulation results show the effectiveness of the proposed algorithm.
متن کاملA Self-Organized Resource Allocation using Inter-Cell Interference Coordination (ICIC) in Relay-Assisted Cellular Networks
In a multi-cell scenario, the inter-cell interference (ICI) is detrimental in achieving the intended system performance, in particular for the edge users. There is paucity of work available in literature on ICI coordination (ICIC) for relay-assisted cellular networks (RACN). In this paper, we do a survey on the ICIC schemes in cellular networks and RACN. We then propose a self-organized resourc...

متن کاملDynamic Distributed Resource Allocation in Relay Assisted OFDMA Networks
Relay assisted OFDMA networks are promising solutions for provision of high-data-rate services in wide coverage areas. However, the deployment of relays makes the resource allocation a more challenging and complex task. In this paper we study dynamic allocation of power and subchannels in an OFDMA downlink system with regenerative relays which have the capability of buffering the users’ data to...
