Abstract:

In frequency reuse one networks, the inter-cell interference (ICI) is severe especially for cell edge user equipments (UEs). Statistical information of ICI is helpful to design interference mitigation schemes. This paper proposes a statistical model for the uplink ICI in orthogonal frequency division multiple access (OFDMA) networks with power control. The distance-dependent attenuation and correlated shadowing are included in the channel model. Through analyzing the random part related to distribution of user's location and correlated shadowing, we derive the general parametric probability density function (PDF) of uplink ICI in logarithmic domain, and then use the derived model to investigate the distribution of ICI with typical power control schemes. Numerical results derived from theoretical calculations and Monte Carlo simulations verify the statistical model and the analysis.
