Abstract

Perkembangan teknologi 5G New Radio telah dikomersialkan oleh beberapa operator seluler di beberapa negara dengan strateginya masing-masing. Sementara itu, dengan akan mulai diimplementasikannya 5G di Indonesia, sumber daya spektrum frekuensi yang dimiliki oleh setiap operator telah dialokasikan untuk teknologi existing 2G, 3G dan 4G. Spektrum frekuensi termasuk sumber yang terbatas dan mahal. Perencanaan radio frekuensi merupakan tahapan penting untuk memaksimalkan kualitas dan kapasitas jaringannya. Berdasarkan 3GPP release-15, teknologi NR mempunyai fitur teknologi Dynamic Spektrum Sharing (DSS) yang mendukung teknologi 4G dan 5G dapat menggunakan alokasi spektrum frekuensi yang sama.[1]. Pada penelitian ini dilakukan perencanaan jaringan 5G NR dengan menggunakan teknik Dynamic Spectrum Sharing pada frekuensi existing teknologi LTE. Studi kasus dilakukan di kota Tangerang Selatan pada frekuensi 900 MHz dan 1800 MHz. Simulasi dilakukan menggunakan software Atoll 3.4.0 dengan model propagasi Urban Macro (UMa) yang telah distandarisasi oleh 3GPP TR 38.901. Berdasarkan hasil perhitungan perencanaan dan simulasi jumlah kebutuhan site sebanyak 72 site untuk dapat mengakomodir kebutuhan coverage dan capacity di kota Tangerang Selatan. Dengan menggunakan teknik DSS, hasil simulasi cakupan radio frekuensi 5G dengan parameter pengujian SS-RSRP diperoleh rata-rata sebesar -91,25 dBm. Sedangkan, hasil simulasi kualitas 5G dengan parameter pengujian SS-SINR diperoleh rata-rata sebesar 12,99 dB. Sementara itu, hasil simulasi kecepatan akses jaringan dengan parameter pengujian datarate mencapai rata-rata 90,24 Mbps.Kata kunci— SA, 5G NR, LOS, NLOS, UMa

Abstract

Underwater Visible light communication (UVLC) is a network communication wirelessly where information is transmitted employing light through visible waves; in this case, the light source comes from a light-emitting diode (LED) as a transmitter underwater. VLC has several advantages over radio frequency technology, such as safer communication because light propagation cannot penetrate the wall, so it is difficult to do hacking, easy to get a license, relatively build cheap cost, and has no side effects on health. However, VLC has several limitations, one of which is the narrow bandwidth modulation. VLC undergoes a distribution of modulated bandwidth to allocate against each user. This bandwidth sharing has an impact on reduced system capacity. This study applied non-orthogonal multiple access (NOMA) to increase system capacity. This research analyzes the performance of the two best power allocation methods in a water medium, including gain ratio power allocation (GRPA) and static power allocation (SPA). In the results obtained in the NOMA-UVLC power allocation value, GRPA is more stable than SPA power allocation. Then applying residue in the successive interference cancellation (SIC) process will result in a decrease in system capacity compared to no residue in the SIC process. This study found that the GRPA power allocation is more stable in capacity performance compared to the application of SPA power allocation. Average capacity increase of 48.5% in GRPA power allocation

Abstract

The number of cellular users (CU) continues to increase in Indonesia. This impacts a large network load for the number of devices connected to the main network so it will have an impact on the quality of service. Device-to-Device (D2D) communication as components for LTE-A technology enabling a direct wireless link between the CUs without routing the data via the evolved Node B (eNB) signal or the core network. The need for algorithm and power control used to allocate radio resources so it can get a good quality of service because of communications technology D2D. In this study, we analyze and compare the performance parameters of D2D communication systems, including system interference, system sum-rate, system spectral efficiency, total energy system, and system energy efficiency based on Genetic and Greedy Algorithms in allocating radio resources and controlling the power of users. The genetic algorithm works with three operators in allocating resource block (RB), including proportional selection, crossover, and mutation. This process is repeated many times to produce several generations so that the best allocation can be got. The genetic algorithm has a flexible number of D2D and cellular communications in several RBs, minimum signal to interference plus noise ratio (SINR) also considered for mobile communication in ensuring the quality of its services. Numerical evaluations demonstrate the superior performance of the Genetic Algorithm in terms of system power, energy efficiency, and interference mitigation. As repetition gets larger, the Genetic algorithm results in better spectral efficiency.
