Abstract

Pojavom sve većih zahtjeva u vidu povećanog kapaciteta, velikog broja mobilnih veza, smanjene latencije te povećane pouzdanosti bilo je potrebno LTE arhitekturu zamijeniti novom radijskom tehnologijom NR. Ovaj rad donosi kratak opis NR RAN arhitekture kao i poboljšanja unutar radijske pristupne mreže u odnosu na LTE RAN. Mnoga poboljšanja su potrebna kako bi bilo omogućeno učinkovito raspoređivanje resursa korisnicima u cilju ispunjenja QoS zahtjeva različitih tipova prometa predstavljenih u novoj 5G mreži, a to su eMBB, mMTC i URLLC prometi. Osim osnovnih algoritama raspoređivanja koji su se koristili u LTE tehnologiji, opisani su novi algoritmi raspoređivanja u 5G mreži koji su predstavljeni u najnovijim izdanjima znanstvenih časopisa. EDF algoritam raspoređivanja koji se koristi u sustavima za rad u stvarnom vremenu je implementiran i prilagođen raspoređivanju radijskih resursa. Predstavljeni su rezultati niza simulacija sa različitim tipovima prometa kako bi se ocijenila učinkovitost EDF algoritma raspodjele radijskih resursa.

Abstract (english)

With the emergence of increasing demands in the form of increased capacity, a large number of mobile connections, reduced latency and increased reliability, it was necessary to replace the LTE architecture with new radio technology NR. This paper provides a brief description of the NR RAN architecture as well as improvements within the radio access network compared to LTE RAN. Many improvements are needed to enable efficient allocation of resources to users in order to meet the QoS requirements of the different types of traffic represented in the new 5G network, namely eMBB, mMTC and URLLC traffic. In addition to the basic scheduling algorithms used in LTE technology, new scheduling algorithms in the 5G network are described and presented in the latest issues of scientific journals. The EDF scheduling algorithm used in real-time systems is implemented and adapted to the scheduling of radio resources. The results of a series of simulations with different types of traffic are presented to evaluate the efficiency of the EDF algorithm of radio resource allocation
