Exponential effective signal-to-interference plus noise ratio mapping, also known as EESM, is a link-to-system level (L2S) interface that have been successful to exchange information between a system-level simulator (SLS) and a link-level simulator (LLS). However, in some special adverse conditions, such as where the Gaussian distribution does not hold for the interference term, the accuracy provided may not be suitable to radio resource management and link adaptation algorithms. If, on the one hand, the effective channel quality facilitates creating the lookup tables as well as mapping throughout them, on the other hand, it can erroneously lead SLS to obtain similar results for distinct physical-level states. This work addresses that issue and devises a workaround solution in order to visualize the potential benefits on overcoming this drawback. An extended version of EESM is introduced and, through computer simulations, its improvements are corroborated.
