ABSTRACT
\n\n
This seminar consid ers a system model that characterizes the coupling relation among cell loa d levels in OFDMA networks\, taking into account nonR 08\;uniform traffic demand and the load‐ \;dependent interference between the cells with arbitrary netwo rk topology. Solving the system model enables a network& #8208\;wide performance evaluation in terms of resource efficie ncy. \; Approaching the model directly is however complex due to non‐\;linearity\, multiple dimensions\, and n on‐\;trivial load coupling relations. In the presentation\, we provide a summary of the key mathematically proven properties of the model. The properties allow for designing powerful means for performance assessment in network planning and optimization. The theo retical insights are supported with an illustrative example of using the c ell load coupling model for evaluating network configuration\, along with perspectives of potential applications in planning and performance enginee ring of LTE/LTE-A and heterogeneous networks.
