Разработаны математические модели для анализа вероятностных характеристик спектральной эффективности нисходящих радиоканалов в макросайтах систем мобильной (сотовой) радиосвязи, выполнены оценки вероятностных распределений и средних значений потенциальной и реальной спектральной эффективности нисходящих радиоканалов для различных вариантов типовых сценариев IMT-2020 “Rural-eMBB”, “Urban Macro–mMTC” и “Urban Macro–URLLC”. Полученные модели и оценки учитывают случайность местоположения абонентских терминалов на территории макросайта и возможность присутствия в нем областей как свободного, так и интерференционного (многолучевого) распространения радиоволн между базовой станцией и абонентскими терминалами. Эти результаты позволяют сделать вывод о реализуемости деклараций новых поколений мобильной радиосвязи в части повышения спектральной эффективности радиоканалов в процессе эволюции 4G→5G→6G.

Mathematical models for the analysis of probabilistic characteristics of the spectral efficiency of downlink radio channels in macro-sites of mobile (cellular) radio communications have been developed, and estimates of the probability distributions and average values of the potential and real spectral efficiency of downlink radio channels have been made for various variants of the typical IMT-2020 scenarios “Rural-eMBB”, “Urban Macro–mMTC” and “Urban Macro–URLLC”. Obtained models and estimates take into account the randomness of the user’s equipment distribution on the macro-site territory and the possibility of user’s equipment location in areas of both free and interference (multi-ray) propagation of radio waves between the base station and user’s equipment. These results allow us to conclude that the declarations of new generations of mobile communications in terms of increasing the spectral efficiency of radio channels at the 4G→5G→6G evolution are feasible.
