With the development of release and retrieval technology for unmanned air vehicles (UAVs), the aerial cluster platform composed of carrier aircraft and multiple rotor UAVs can be used as a new approach for mobile emergency broadcasting operations. It indicates that we can resolve the paradoxical relationship between limited endurance of UAVs and large scale mission area. This paper proposes a region scanning strategy based on the aerial UAV cluster platform. The system can achieve all-region broadcasting in disaster ares, as well as audio and video collection for disaster assessment and emergency rescue.

5G Broadcast is one of the most relevant verticals of the fifth mobile generation. It brings greater efficiency to the network by providing multicast and broadcast capabilities rather than allowing multiple unicast transmissions of the same content to various users. The service defined by the 3rd Generation Partnership Project that provides these capabilities is called Multimedia Broadcast Multicast Service, which has evolved over several releases introducing enhanced capabilities. In addition, thanks to the revolution caused by the virtualization of technologies, a cloud-based multi-vendor mobile network infrastructure, among which open-source platforms stand out, has become possible. Based on the OpenAirInterface and srsRAN open-source platforms, this paper evaluates the potential of Multimedia Broadcast Multicast Service specifications, such as evolved Multimedia Broadcast Multicast Service and Further evolved Multimedia Broadcast Multicast Service, for transporting content streams over mobile networks and compares the two specifications in terms of their performance.

Data traffic has skyrocketed as a result of the global proliferation of rich media services. A number of cutting-edge applications are predicted to be supported by 5G networks across the three categories: enhanced mobile broadband, ultra-reliable low latency communications, and enormous machine-type communications. The expectations and goals for the various services in the 5G networks have put a lot of pressure on mobile operators to maintain high Quality of Experience (QoE). The use of 5G Heterogeneous Networks (HetNets), which will provide consumers with the ability to be associated with either Macro Base Stations (MBS) or small cells, is one of the most promising solutions. Among the small cells, femtocells have drawn much attention recently. Yet, the most significant challenge with the deployment of femtocells is the high co-tier interference that can occur between different femtocell users. Artificial Intelligence (AI) and Machine Learning (ML)-based solutions are being incorporated in 5G networks to address this challenge. In this paper, we propose a ML Multi-Classification and Offloading Scheme (MLMCOS) to mitigate co-tier interference in 5G HetNets. MLMCOS classifies users into multiple classes based on their service priority along with their experienced co-tier interference. It then offloads some of them to the nearby Femto Base Stations (FBS) based on the availability of resources to ensure high QoE. ML classification algorithms are evaluated in terms of accuracy, recall, and precision. The performance of MLMCOS is then compared to those of Proportional Fair (PF) scheduling algorithm, Variable Radius and Proportional Fair scheduling (VR+PF) algorithm, and a Cognitive Approach (CA) in terms of Video Multimethod Assessment Fusion (VMAF), R-Factor, and RUM Speed Index (RUMSI).

The introduction of co-construction and sharing makes the network structure increasingly complex. The 5G network should meet the business needs of both operators. How to evaluate the network perception of both users more comprehensively has become a new challenge. This paper proposes a 5G network evaluation method based on perceptual peer-to-peer. The big data modeling is used to determine the judgment criteria for perceived peer-to-peer, and the difference ranking is selected to intuitively reflect difference degree of the area where the community to be evaluated is located. This research can intuitively reflect the perception equivalence of different regions and the contribution of different indicators, and provide an objective basis for subsequent targeted network optimization and adjustment.

In 5G-advanced and 6G network, satellite communications network and terrestrial communication network will be integrated, which is capable of providing global coverage and supporting large-scale user access. In integrated satellite-terrestrial network (ISTN), users have two optional access methods, satellite access or terrestrial radio station access. To efficiently utilize resources, it is a challenging task to assist users to select the optimal access method. In this paper, we propose a dynamic selection mechanism of access strategies with the goal of minimizing user expenses, jointly optimizing the user’s energy consumption and application server resources. Simulation results demonstrate that the proposed mechanism is feasible under various scenarios.

The second generation of digital video broadcasting for terrestrial transmission (DVB-T2) and Advanced Television Systems Committee (ATSC) 3.0 are based on Orthogonal Frequency Division Multiplexing (OFDM) modulation. As known, OFDM has a very high peak-to-average power ratio (PAPR) which affects the system performance in presence of nonlinear power amplification. Many algorithms have been proposed to reduce the PAPR effect on the transmitted signal. The DVB-T2 and ATSC 3.0 standards adopted the technique of tone reservation (TR) which is based on an iterative process where a predefined kernel is applied to reduce a peak power at each iteration. In this paper, the Iterative Dichotomy PAPR reduction method (IDP) is used to reduce the PAPR of both DVB-T2 and ATSC 3.0 standards. The simulation results show that IDP-based PAPR reduction exhibits a gain of 2 dB, in terms of PAPR reduction, compared to TR.

Some countries and regions are currently considering 5G services in the 3.5 GHz band, and the widespread deployment of 5G systems may cause interference to Fixed Satellite Service (FSS) earth stations operating in adjacent frequency bands. This paper presents an analysis for 5G base station downlinks in 3.5 GHz band when receiving adjacent FSS earth stations, derived from ITU-R recommendations for IMT and FSS. The conclusions of the study give the minimum required protection distances for coexistence deployment of 5G systems with FSS earth stations at different frequency intervals. Various feasible technical measures for inter-system coexistence protection, such as adding frequency shielding, adding filters, limiting out-of-band indicators of base stations and setting geographic protection ranges, are also proposed considering the complex scenarios of the actual system deployment.

Vehicle Ad Hoc Network (VANET) is one of the important means to realize intelligent transportation system, which can improve road safety and traffic efficiency. At present, two key technologies of vehicle communication include DSRC (Dedicated Short-Range Communication) and LTE (Long Term Evolution). After 20 years of in-depth research, DSRC has reached sufficient technical maturity, but its performance improvement space is relatively limited. LTE is a relatively new 3GPP-based standard and is considered the strongest competitor to IEEE 802.11p.There are many mature analysis models in DSRC reliability analysis, however as LTE is a newly emerging vehicle networking technology, the existing analysis models have some problems that do not conform to actual traffic scenarios and incomplete analysis of beacon transmission errors. Although technological innovations allow LTE to have many features over DSRC, studies have found that DSRC outperforms in some respects.Given the existing shortcomings of analysis models, this paper proposes an LTE broadcast performance analysis model based on the Poisson distribution traffic model. This model uses the Markov State Transition Process to evaluate the probability of packet reception for LTE combined with four transmission errors. The numerical results of the analysis model is cross-validated through the network simulation results obtained by the MATLAB simulator, which proves the correct-ness of the model.

Mobile communications services are under continuous enhancement, resulting in the introduction of new transmission and reception techniques, new equipment designs and the use of new frequency bands. However, with the development of technology, and especially, with the rapid advancement of 5G services, social concern about the potential harmful effects of wireless communication networks has also increased. In order to guarantee health safety in wireless networks, human exposure to electromagnetic fields generated by radio communication systems is usually tested to check compliance with regulations. This can be done by measuring received signal strengths and comparing them with exposure limits. This paper presents an evaluation of electromagnetic exposure due to 5G mobile communications in outdoor environments. A measurement campaign was carried out in several locations of the city of Bilbao using professional equipment in order to acquire 5G signal data in different environments. Then, recorded data was processed and analyzed in order to characterize electromagnetic exposure according to the scenario and frequency band. Finally, a comparison with exposure limits and with the results derived from a previous measurement campaign carried out a year before is presented.
