Evaluación de numerologías 5G para URLLC Segura, David Khatib, Emil Jatib Barco-Moreno, Raquel Sistemas de comunicaciones móviles In the last years, there is a growing trend to automate and integrate data exchange mechanisms in manufacturing processes, known as Industry 4.0. The fifth generation of mobile phone technologies (5G) is presented as one of the main options through its service categories. Ultra-Reliable and Low Latency Communications (URLLC) is the type of communication used by critical mechanisms, with a millisecond end-to-end delay and reduced probability of failure. In order to achieve the delay requirement, 5G defines new numerologies, with different SubCarrier Spacing (SCS) and cyclic prefix, together with mini-slots for a faster scheduling. The main challenge of this is to select the appropriate numerology according to radio conditions and packet size. In this paper, we evaluate the delay measured in the radio link, specifically, at PDCP (Packet Data Convergence Protocol) layer, for each numerology in LOS and NLOS conditions in order to asesss which of them suits better URLLC delay requirements. 2020-09-18T11:29:30Z 2020-09-18T11:29:30Z 2020 2020-09-18 conference output https://hdl.handle.net/10630/19802 spa XXXV Simposio Nacional de la Unión Científica Internacional de Radio, URSI 2020 Málaga (Remoto), España 2/9/2020 open access
