en 5-Communication Systems Communication Systems Research Paper Research Paper <span style="font-size:10.0pt"><span new="" roman="" style="font-family:" times="">The progress of 5G networks is propelled by wireless technology, specifically mobile internet and smart devices. This article provides an in-depth analysis of the fundamental elements of 5G technology, encompassing the advancement of cellular networks, simultaneous transmission capabilities, energy efficiency enhancements, and the implementation of cooperative communication. This study examines the application of simultaneous wireless information and power transfer (SWIPT) in cooperative device-to-devices (D2D) communication. Specifically, it investigates relay selection using decode-forward (DF) protocols and considers the issue of self-interference. Radio frequency based energy harvesting (RF-EH) is proposed to address power limitations in device-to-device (D2D) communication. This article describes the development of this technology and suggests a system architecture that employs time-switching relaying (TSR) techniques to enhance the power efficiency of base stations. This research aims to assess data transfer efficiency in two-way cooperative communication systems by incorporating many technologies.</span></span> D2D Communication, DF Protocol, RF-EH with TSR, Throughput. 133 143 http://ijeee.iust.ac.ir/browse.php?a_code=A-10-4962-3&slc_lang=en&sid=1 Tasqiatul Qulbi Kamila Huda tasqiatulqulbi@te.student.pens.ac.id 1800319475328460014058 1800319475328460014058 No Politeknik Elektronika Negeri Surabaya I Gede Puja Astawa puja@pens.ac.id 1800319475328460014059 1800319475328460014059 Yes Politeknik Elektronika Negeri Surabaya Yoedy Moegiharto ymoegiharto@pens.ac.id 1800319475328460014060 1800319475328460014060 No Politeknik Elektronika Negeri Surabaya Mohamad Ridwan ridwan@pens.ac.id 1800319475328460014061 1800319475328460014061 No Politeknik Elektronika Negeri Surabaya Budi Aswoyo budias@eepis-its.id 1800319475328460014062 1800319475328460014062 No Politeknik Elektronika Negeri Surabaya Anang Budikarso anang_bk@pens.ac.id 1800319475328460014063 1800319475328460014063 No Politeknik Elektronika Negeri Surabaya Ida Anisah ida@pens.ac.id 1800319475328460014064 1800319475328460014064 No Politeknik Elektronika Negeri Surabaya Faridatun Nadziroh faridatun@pens.ac.id 1800319475328460014065 1800319475328460014065 No Politeknik Elektronika Negeri Surabaya
