abstract = {In the last years, 5G New Radio (NR), introduced in 2019 in the 3rd Generation Partnership Project (3GPP) Release 15, has become the global radio standard for 5G networks. The increasing number of available 5G gNodeBs (gNBs) makes handover management crucial, especially from the point of view of the Quality of Experience (QoE) of a User Equipment (UE). In order to analyse the handover behaviour in 5G networks, we derive a Matlab-based simulator for location-based handover management. As a first step, an accurate simulation model of an experimental 5G NR communication system is derived. In detail, the performance results are expressed in terms of Reference Signal Received Power (RSRP) 5G NR signal quality metric, measured on the Channel State Information (CSI) Reference Signal (RS) on a DownLink (DL) transmission from a gNB to a mobile UE. In order to derive an accurate simulator, we rely on an experimental testbed based on the use of a commercial wireless 5G embedded modem positioned in a moving vehicle and collecting geolocalized RSRP values.},

abstract = {Nowadays, the deployment of 5G Non-StandAlone (NSA) networks has led to significant enhancements in the User Equipment (UE) experience, in particular in terms of latency reduction and throughput increase. To this end, 5G gNodeBs (gNBs) offer broad coverage but may face challenges in areas with low signal strength, resulting in a Quality of Service (QoS) degradation and too short connections to distant gNBs (denoted as Unnecessary HandOvers, UHOs) due to geographic peculiarities. In order to tackle these issues, in this paper the use of cost-effective 5G small cells in critical areas is considered, aiming at (i) boosting coverage, (ii) enhancing UE QoS, and (iii) avoiding UHOs, thus improving HO performance and UE QoS.},
