Pengendali mudah alih sistem komunikasi mudah alih generasi kelima (5G) perlu meneroka kes penggunaan dan/atau aplikasi baharu bersama-sama dengan industri menegak, industri yang merupakan pengguna berpotensi 5G, untuk mengeksploitasi sepenuhnya keupayaan 5G baharu dari segi aplikasinya. Komunikasi kenderaan untuk platun dianggap sebagai salah satu kes penggunaan baharu 5G yang memerlukan kependaman rendah dan kebolehpercayaan ultra. Kertas kerja ini membentangkan penilaian lapangan kami tentang kependaman dan prestasi kebolehpercayaan komunikasi Langsung 5G V2V ke arah aplikasi kepada platun trak. Pengarang membina persekitaran percubaan lapangan, untuk komunikasi V2X platun trak, dengan trak bersaiz besar sebenar dan sistem prototaip yang menggunakan teknologi Radio Baharu (NR) 5G, dan melakukan beberapa eksperimen lapangan di kawasan luar bandar. Dalam kertas kerja ini, kami memperkenalkan sistem prototaip 5G NR-V2X. Ciri yang paling tersendiri ialah sistem prototaip dilengkapi dengan antara muka radio komunikasi Langsung V2V (iaitu, pautan sisi), sebagai tambahan kepada antara muka radio tradisional antara BS dan UE (iaitu, pautan bawah dan pautan atas). Kemudian, kami membentangkan hasil penilaian medan hasil persekitaran penyebaran radio dan prestasi penghantaran melalui udara kependaman dan ciri kebolehpercayaan pada komunikasi Langsung V2V prototaip dalam persekitaran lebuh raya ekspres awam sebenar termasuk kawasan terowong serta kawasan luar terowong, untuk menilai sistem 5G NR-V2X yang digunakan untuk platun trak. Penyebaran radio dan hasil penilaian prestasi kependaman menjelaskan bahawa prestasi kependaman merosot disebabkan oleh penghantaran semula Hybrid Automatic Repeat ReQuest (HARQ) di bahagian luar terowong lebih berkemungkinan daripada bahagian dalam terowong, memandangkan nilai kehilangan laluan yang lebih besar boleh diperhatikan di luar. terowong daripada bahagian dalam terowong, dalam komunikasi V2V Langsung platun trak. Keputusan penilaian kependaman dan kebolehpercayaan over-the-air mengesahkan bahawa adalah penting untuk menetapkan bilangan maksimum penghantaran semula HARQ yang sesuai kerana terdapat masalah tukar ganti untuk merealisasikan kependaman rendah dan kebolehpercayaan yang tinggi secara serentak.

Abstract: Fifth generation mobile communication system (5G) mobile operators need to explore new use cases and/or applications together with vertical industries, the industries which are potential users of 5G, in order to fully exploit the new 5G capabilities in terms of its application. Vehicular communications for platooning are considered to be one of new use cases of 5G whose low-latency and ultra-reliability are required. This paper presents our field evaluations on latency and reliability performance of 5G V2V Direct communication towards application to truck platooning. The authors build a field experimental environment, for V2X communications of truck platooning, with actual large-size trucks and a prototype system employing 5G New Radio (NR) technologies, and performed some field experiments in rural areas. In this paper, we introduce the 5G NR-V2X prototype system. Its most distinctive feature is that the prototype system is equipped with V2V Direct communication radio interface (i.e., sidelink), in addition to the traditional radio interfaces between BS and UE (i.e., downlink and uplink). Then, we present the field evaluation results of radio propagation environment results and over-the-air transmission performance of latency and reliability characteristics on the V2V Direct communication of the prototype in real public express highway environment including tunnel area as well as tunnel outside area, in order to assess 5G NR-V2X system applying to truck platooning. The radio propagation and the latency performance evaluation results clarify that the latency performance is degraded due to Hybrid Automatic Repeat reQuest (HARQ) retransmission at the outside of tunnel more possibly than the inside of tunnel, since larger path loss values can be observed at the outside of tunnel than the inside of tunnel, in V2V Direct communications of truck platooning. The over-the-air latency and reliability evaluation results confirm that it is important to set an appropriate maximum number of HARQ retransmissions since there is a trade-off problem in order to realize low latency and high reliability simultaneously.
