В работе описаны выявленные недостатки существующей схемы прерывистого приема, используемой для энергосбережения пользовательского оборудования в 5G NR. Путем имитационного моделирования системы проведен детальный анализ эффективности снижения потребления энергии пользовательским оборудованием при использовании схемы прерывистого приема для различных моделей трафика и ключевого сценария развертывания систем беспроводной сотовой мобильной связи 5G. Анализ результатов моделирования показал, что использование схемы прерывистого приема не позволяет достичь верхней границы возможного энергосбережения для всех исследованных моделей трафика по ряду причин, описанных в данной работе.</p></abstract><trans-abstract xml:lang="en"><p>The purpose of this work is to analyze the energy saving schemes of user equipment in the first releases (Release 15) of the fifth generation (5G NR) cellular mobile communication systems, as well as to identify possible ways to improve the energy efficiency of these systems. The paper describes the identified drawbacks of the existing discontinuous reception scheme (DRX-scheme) used for user equipment energy saving in 5G NR. The effectiveness of discontinuous reception scheme in reducing user equipment energy consumption was analyzed in detail by simulation study for various traffic models and a key scenario for the deployment of 5G wireless cellular mobile communication systems. Analysis of the simulation results shows that the discontinuous reception scheme does not reach the upper limit of possible energy saving for all the traffic models studied for a number of reasons described in this paper.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>системы радиосвязи</kwd><kwd>энергосбережение</kwd><kwd>схема прерывистого приема</kwd><kwd>DRX</kwd><kwd>приемо-передающее оборудование</kwd><kwd>алгоритмы цифровой обработки сигналов</kwd><kwd>5G NR</kwd></kwd-group><kwd-group xml:lang="en"><kwd>radio communication systems</kwd><kwd>energy saving</kwd><kwd>discontinuous reception scheme</kwd><kwd>DRX</kwd><kwd>receiving and transmitting equipment</kwd><kwd>digital signal processing algorithms</kwd><kwd>5G NR</kwd></kwd-group><funding-group xml:lang="ru"><funding-statement>исследование выполнено при финансовой поддержке РФФИ в рамках научного проекта № 20-32-90197</funding-statement></funding-group><funding-group xml:lang="en"><funding-statement>This research was funded by RFBR according to the research project No. 20-32-90197</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Dahlman E., Parkvall S., Skold J. 5G NR: The Next Generation Wireless Access Technolog.
