| Abstract | The fifth generation (5G) and beyond networks have the potential to meet the increasing demands of emerging applications and industry verticals for high throughputs and reliable low latency communication under various mobility scenarios. Also, there is a great demand for new user experiences that would require greater uplink performance from these networks. To meet these expectations from 5G networks, critical gaps need to be filled before they can be fully implemented for mobile applications in complex environments like smart cities. Millimeter wave frequencies can significantly increase the performance of these networks, but they also suffer from reliability issues due to limited transmission range. Many uplink enhancement technologies, like multi-connectivity, carrier aggregation, etc., have been proposed to improve the performance, but they all either add to the user equipment (UE) complexity or increase the deployment costs. We develop a novel multilink scheme for the uplink where the UE performs only a single transmission on a common channel, and every base station that receives this signal would accept and process it. Our solution reduces frequent handovers and allows high UE mobility with no additional complexity. We propose and evaluate this novel 5G deployment with multilink using the Simu5G network simulator for enabling future 5G systems. The proposed 5G architecture is shown to meet the requirements of next-generation applications. Our simulations show that the proposed technique improves the throughput by up to 54%, the latency by up to 27.61%, and the reliability by up to 91.36% compared to a single link system. © 2023 IEEE. |
