Desarrollo de un simulador parametrizable de 5G-new radio para la planificación de celdas urbanas.

Abstract

The objective of the titration work was to develop a parametrizable simulator in the Matlab © software, which allows a user to have the possibility of experimenting with the different parameters of 5G-NR and identify its primary characteristics at the link level and wave propagation. For this, essential parts of the standard were analyzed and introduced into functions in the Matlab © software. The physical downlink shared channel and the physical uplink shared channel could be parameterized. In addition to this, it includes two urban cell planning models using the 'site viewer' tool. On the one hand, a model uses SINR Maps within topographic maps, thus visualizing the reception ranges to the user. Secondly, a model was implemented with Ray-Tracing in 3D Maps take into account the buildings, the terrain, and their materials, and from this calculate the Power Delay Profile, and if there is movement, the Doppler displacement generated by it. Thus, making it possible not only to show results at the physical layer level but also to experiment with frequencies and test parameters in more visual environments, resulting in a parameterizable simulator that integrates each of these points and makes them reach the user through a simplified user interface. In the end, an applicability survey was carried out. It is evidenced that the development of simulators is of great help for users to approach the possible implementations of the technologies studied. It is advisable to use the simulator in its Matlab App format to utilize all its functionalities.
