Ítem Evaluación del rendimiento de una red móvil 5G en el enlace de bajada utilizando diferentes algoritmos de planificación de recursos.Córdoba Daza, Angie Carolina; Contreras Niño, Juan Camilo; Cadena Muñoz, ErnestoWith the implementation of the Fifth Generation of Cellular Wireless Standards (5G) within society, an improvement in the services of many branches of information and communication technologies is projected, which will supply all the massive demand for mobile broadband access presented by users who make use of various services today, services such as web access, applications, cellular technology, among others. This new technology brings with it improvements of the Long Term Evolution (LTE) technology in its advanced version, contributing to the heterogeneity of radio technologies, flexibility, reconfiguration and resilience of the system [1]. It is also planned to make possible the use of new applications, such as industrial wireless control, autonomous vehicles, high quality virtual reality, remote healthcare, among others [2].Within the following paper, the performance of the 5G network with different resource schedulers is verified through a simulator implemented in Matlab, which allows variations within the characteristics that make up the scenario. The system is based on Frequency Division Duplexing (FDD), with which the downlink schedulers that make this dynamic resource allocation possible are examined. The schedulers to be considered are Round Robin, Proportional Fairness and Best CQI. A system level simulator is implemented, which contains the characteristics of a specific scenario to evaluate each scheduler, the performance is analyzed based on throughput, goodput and Fairness. A sequential linear methodology is used, which begins by defining the characteristics and components that make up the 5G network, then the design and implementation phases of the scenarios are detailed, the key data that will change to verify the behavior in the network, and then the simulation process where the results of each simulation will be obtained, these results are organized in such a way that the change that implies having more bandwidth or more users in the same cell, according to the resource planning algorithm implemented, can be evaluated. The results obtained from each simulation show the close relationship between the resource planning algorithms and the performance of the 5G network, due to the increase in Mega bits per second (Mbps) when using one or the other, with the Best Channel Quality Indicator, Best CQI (BCQI) algorithm a great performance is obtained but the allocation capacity is low, There are users who do not receive any time and frequency resources for transmission and others remain with enough at the moment, there is not as much equity as with the Proportional Fairness and Round Robin algorithms, the latter two distribute the resources equally with up to 50% better than BCQI, therefore there is an efficient distribution of resources.
