The estimation of cellular networks capacity mainly depends on the characterization of interference. As downlink is often the limited link w.r.t. capacity, the authors focus on this direction throughout this paper, although the proposed framework can easily be extended to the uplink. In cellular networks, an important parameter for this characterization is the Other-Cell Interference Factor f (OCIF). The precise knowledge of the OCIF allows the derivation of outage probabilities, capacity evaluation and then, the definition of Call Admission Control mechanisms. In this paper, they define OCIF as the ratio of total other-cell received power to the total inner-cell received power.
