Network slicing at the radio access network (RAN) domain, called RAN slicing, requires elasticity, efficient resource sharing, and customization. In this scenario, scheduling (RRS) is responsible for dealing with scarce limited frequency spectrum resources available domain while fulfilling slice intents. The wide variety of scenarios supported in 5G beyond networks makes RRS problem scenario a significant challenge. This paper proposes an intent-aware reinforcement learning method to perform...
The modernization of business processes have pressured Software-Intensive Information Systems (IS) to interoperate with several types systems, such as cyberphysical drones, satellites, and mobiles, arising a new type complex systems so-called Systems-of-Information (SoIS). Despite the novelty area it has been known, follows trend previous Federated Large-Scale Systems. However, operational managerial independence IS constituents created system that must be understood suitably support...
The main goal of this article is to present the fundamental theoretical concepts for tutorial presented in IEEE NetSoft 2020. explores use software 5G system composed Radio Access Network (RAN) and core components, following standards defined by 3GPP, particularly Release 15. provides a brief overview mobile cellular networks, including basic concepts, operations, evolution through called `generations' networks. From perspective, RAN context 4G which includes virtualization disaggregation...
Fifth-generation (5G) cellular communication systems have embraced massive multiple-input-multiple-output (MIMO) in the low- and mid-band frequencies. In a multiband system, base station can serve different users each band, while user equipment operate only single band simultaneously. This paper considers MIMO system where channels are dynamically allocated frequency bands. We treat as scheduling resource allocation problem propose deep reinforcement learning (DRL) agents to perform...
The virtualized radio access network (vRAN) placement problem consists of jointly choosing a functional split and the functions on vRAN nodes scattered in network. most prominent solutions present optimal approaches to solve problem, but they are computationally expensive for large instances. Non-exact emerge as alternatives mainly using machine learning, which is largely fostered by standardization bodies next-generation networks. In this context, we an approach deep reinforcement learning...
Disaggregated and virtualized RANs (vRANs) offer the opportunity for flexible efficient use of computing resources through proper placement RAN Virtualized Network Functions (VNFs). However, many works neglect necessary coordination between VNF pro-cessing tasks inside these VNFs. This can negatively impact important such as resource scheduling interference control. In this work, we introduce a new approach that is aware wireless coverage its associated tasks. Our solution was designed in...
Redes de Acesso por Rádio Próxima Geração (NG-RAN) devem suportar oito opções divisões funcionais combinando o posicionamento em três nós, i.e., Unidade Central, Distribuída e Rádio. Além disso, esses nós trabalhar forma virtualizada, resultando uma solução vNG-RAN. Neste artigo, é proposto um modelo otimização exato que tem como objetivo VNFs para planejamento vNGRAN com possibilidade divisão do fluxo roteamento múltiplos caminhos. Entretanto, nossos testes apresentam esta abordagem complexa...
