  • On Multi-Cell Uplink-Downlink Duality with Treating Inter-Cell Interference as Noise
    arXiv: Information Theory, 2019
    Co-Authors: Hamdi Joudeh, Bruno Clerckx
    Abstract:

    We consider the information-theoretic optimality of treating inter-Cell Interference as noise in downlink Cellular networks modeled as Gaussian interfering broadcast channels. Establishing a new uplink-downlink duality, we cast the problem in Gaussian interfering broadcast channels to that in Gaussian interfering multiple access channels, and characterize an achievable GDoF region under power control and treating inter-Cell Interference as (Gaussian) noise. We then identify conditions under which this achievable GDoF region is optimal.

  • reverse link power control for managing inter Cell Interference in orthogonal multiple access systems
    Vehicular Technology Conference, 2007
    Co-Authors: Anil M Rao
    Abstract:

    Several next generation mobile wireless technologies have adopted orthogonal multiple access techniques in the reverse link. An orthogonal reverse link implies that same Cell (or intra-Cell) Interference is no longer the dominating factor limiting system performance, rather it is the Interference from mobile transmissions in neighboring Cells (inter-Cell Interference) which ultimately limits the performance of the system, especially with a reuse factor of 1. In this work we propose a simple reverse link power control scheme which is effective in managing the Interference generated to neighboring Cells. Parameterization of the power control scheme allows flexible tradeoff between overall spectral efficiency and Cell-edge bit rates. In addition, we show that the variance of the inter-Cell Interference distribution is reduced compared to existing power control methods, which leads to significantly improved system performance.

  • VTC Spring - The Inter-Cell Interference Dilemma in Dense Outdoor Small Cell Deployment
    2014 IEEE 79th Vehicular Technology Conference (VTC Spring), 2014
    Co-Authors: Michele Polignano, Preben Mogensen, Panagiotis Fotiadis, Lucas Chavarria, Ingo Viering, Paolo Zanier
    Abstract:

    The deployment of low-power small Cells is envisaged as the main driver to accommodate the mobile broadband traffic growth in Cellular networks. Depending on the spatial distribution of the user traffic, a densification of the small Cells may be required in confined areas. However, deploying more and more Cells in given areas may imply an increase of the inter-Cell Interference among the small Cells. This study aims at investigating if the inter-Cell Interference among outdoor small Cells may represent an impairment to the user experience, and evaluates if and in what conditions the Interference coordination is worthwhile compared to the universal frequency reuse. Results show that the inter-Cell Interference depends on the small Cell deployment in the urban environment (e.g. streets and squares) and on the network load condition. In case of deployment along urban streets, the inter-Cell Interference does not affect the user throughput and no Interference coordination is required. On the other hand, if deployed in open areas (e.g. city squares) the Interference coordination enhances both average and coverage user throughput in case of high network load condition.

  • VTC Spring - Autonomous Inter Cell Interference Avoidance under Fractional Load for Downlink Long Term Evolution
    VTC Spring 2009 - IEEE 69th Vehicular Technology Conference, 2009
    Co-Authors: Sanjay Kumar, Guillaume Monghal, Jaume Nin, Ivan Ordas, Klaus I. Pedersen, Preben Mogensen
    Abstract:

    The main source of Interference in OFDMA system in downlink is inter-Cell Interference, which can severely limit the throughput of users near the Cell edge. The inter-Cell Interference coordination (ICIC) is one method to improve the performance. In this paper autonomous inter-Cell Interference avoidance schemes under Fractional Load (FL) conditions in the downlink for 3 rd Generation Partnership Project (3GPP) Long Term Evolution (LTE) are proposed. The proposed schemes do not require any inter-Cell signaling for ICIC; rather the decision about the allocation of the spectrum in order to avoid the inter- Cell Interference is taken based on the information available within the Cell itself. We show that the schemes for spectral resource selection is important for FL scenario to avoid high BLER. The proposed schemes further improve the SINR condition therefore higher Cell throughput and coverage are realized.
