In multi-service link budget, the analysis process to calculate the interference degradation or the loading factor takes into account the interference contribution of all the users with their different services. This results in a common link budget, which aims to provide the same cell radius for all the service by trying to match all the acting UE TX powers. It also aims to balance the two links (i.e. UL and DL) without any a priori knowledge of the limiting link in terms of coverage. This process permits us to estimate the actual system interference de
