Simulation Model for a Half-Duplex Channel System in 5G Wireless Access Network
Abstract
Integrated Access and Backhaul (IAB) technology was developed in 2020 to efficiently and flexibly deploy 5G NR (New Radio) networks to meet the growing demand for quality of connectivity, speed and minimal latency. The main feature of the technology is to combine access and backhaul functions in a single wireless system. The technology seeks to minimize the use of fiber optic connections through wireless backhaul. The technology may utilize a duplex or half duplex connection scheme. To minimize interference, frequency separation of duplex in the former case and time separation in the latter case is used. The purpose of the study is to build and analyze a model of a fragment of the IAB network in the form of a mass service system (MS) with two queues and exhaustive service discipline. A simulation model is built and a preliminary numerical analysis is performed.
