Abstract

The wireless communication network has seen rapid growth, especially with the widespread use of smartphones, but resources are increasingly limited, especially indoors. Femtocell, a spectrum-efficient small cellular network solution, faces challenges in distributed power control (DPC) when deployed with distributed users, impacting power levels, and causing interference in the main network. The aim of this research is optimizing user power consumption in co-tier femtocell networks by using the user power treatment. This study proposed the Distributed Power Control (DPC) variation methods such as Distributed Constrained Power Control (DCPC), Half Distributed Constrained Power Control (HDCPC), and Generalized Distributed Constrained Power Control (GDCPC) in co-tier femtocell network. The research examines scenarios where user power converges but exceeds the maximum threshold or remains semi-feasible, considering factors like number of users, distance, channel usage, maximum power values, non-negative power vectors, Signal-to-Interference-plus-Noise Ratio (SINR), and link gain matrix values. In Distributed Power Control (DPC), distance and channel utilization affect feasibility conditions: feasible, semi-feasible, and non-feasible. The result shows that Half Distributed Constrained Power Control (HDCPC) is more effective than Distributed Constrained Power Control (DCPC) in semi-feasible conditions due to its efficient power usage and similar Signal-to-Interference-plus-Noise Ratio (SINR). Half Distributed Constrained Power Control (HDCPC) is also easier to implement than Generalized Distributed Constrained Power Control (GDCPC) as it does not require user deactivation when exceeding the maximum power limit. Distributed Power Control (DPC) variations can shift the power and Signal-to-Interference-plus-Noise Ratio (SINR) conditions from non-convergence to convergence at or below the maximum power level. We concluded that the best performance of Distributed Power Control (DPC) is Half Distributed Constrained Power Control (HDCPC).

Abstract

Penelitian melakukan kajian terkait uji layak operasi jaringan 5G pada frekuensi 2,3 GHz dari salah satu operator seluler di Indonesia. Evaluasi performa jaringan 5G Non-Stand Alone (NSA) diimplementasikan pada dua lokasi di cluster 1 wilayah Pacitan, Jawa Timur yaitu site ZMDU_0406 dan ZMDU_0407. Metode yang digunakan meliputi perancangan skenario pengukuran, pengumpulan data, dan analisa data lapangan berdasarkan pada parameter throughput, Secondary Synchronization Reference Signal Received Power (SS-RSRP), dan Synchronization Signal-to-Noise and Interference Ratio (SS-SINR). Pengujian dilakukan menggunakan dua skenario traffic yaitu FTP Server dan UDP Server pada perangkat IDTrium—ATEL 5G CPE (SDX62) dan aplikasi iperf3. Hasil simulasi berdasarkan cakupan menunjukan bahwa 99% area memiliki kualitas sinyal yang baik yang ditunjukan dengan nilai SS-RSRP > 80 dBm dan SS-SINR >20 dB pada kedua site. Hasil pengukuran FTP Server menunjukan nilai rata-rata throughput sebesar 82 Mbps untuk site ZMDU_0406 dan 107 Mbps untuk site ZMDU_0407. Sementara itu, pengukuran UDP, site ZMDU_0406 memiliki rata-rata throughput 123 Mbps dan site ZMDU_0407 memiliki nilai rata-rata throughput 157 Mbps. Berdasarkan penelitian berikut dapat dikatakan bahwa infrastuktur 5G Non-Stand Alone yang diterapkan di wilayah Cluster 1 Pacitan memiliki performa yang baik untuk aplikasi real time.
