Priority Based Efficient User Scheduling in Quadcopter Assisted 5G Network

Abstract

In the days to come the Fifth Generation (5G) communication is expected to replace Long Term Evolution (LTE) technology and provide seamless efficiency in terms of throughput and latency. 5G uses New Radio (NR) standards which makes use of higher frequency bands to achieve enormous data rate. In times of need 5G communication could be assisted by unmanned aerial vehicles (UAV) during emergency situations such as flood or earthquakes to provide temporary mobile communication service. Due to its ease of maneuverability, UAVs that are equipped with 5G antennas can be made to hover over the geographical areas where mobile communication service is required. But due to the power consideration of UAVs, they can take a payload of limited weight, which makes it to carry a small sized 5G antenna. Because of this it can serve less number of users leaving behind those users who actually need communication the most. And hence there is a need for scheduling prioritized users so that they get the emergency services first. The prioritized users may be the first responders during a disaster or the one who is running a high priority application. A priority based scheduling algorithm which is built on the existing Round Robin MAC scheduler is proposed in this article. More resource blocks (RB) are allotted to prioritized users so that they can send more data with low latency. Simulation is done to calculate throughput and latency which proves that the proposed priority based scheduling gives better performance when compared to the aforementioned existing scheduler. © 2024 IEEE.
