Soluções e dicas para NR FR1 em modo de ligação descendente TDD

O 5G NR é uma tecnologia de rádio especificada pelo 3GPP e lançada no 3GPP versão 15. Ela foi concebida para três casos de uso: banda larga móvel aprimorada (eMBB), comunicações em massa de tipos de máquinas (mMTC) e comunicações ultraconfiáveis de baixa latência (URLLC). Dentre estes três casos de uso, a eMBB representa realmente uma evolução das comunicações móveis em banda larga a partir do padrão LTE. De acordo com os requisitos de desempenho definidos pelo IMT-2020, ao implementar tecnologia 5G são esperados picos de velocidades de transmissão de aplicações eMBB que alcançam 20 Gbps em ligação descendente e 10 Gbps em ligação ascendente, respectivamente. Casos de uso típicos de eMBB são aplicações que requerem elevadas quantidades de dados, tais como streaming de vídeo 8K em alta resolução, realidade virtual (VR), realidade aumentada (AR), etc.A verificação do fluxo de dados máximo que um equipamento de usuário (UE) com suporte a 5G pode alcançar em condições de teste controláveis e determinísticas é um processo essencial durante a fase de projeto do produto. A verificação centrada no desempenho através da identificação de afunilamentos de fluxos de dados e benchmarking de produtos com relação a um dispositivo ideal aprimora significativamente a experiência de usuário ao fim.Este documento concentra o foco na faixa de frequência 5G NR 1 (FR1) com modo duplex por divisão de tempo (TDD) em modo de operação de conectividade dual E-UTRAN New-radio (ENDC). Como a camada física 5G NR proporciona enorme flexibilidade, a motivação neste caso é oferecer um tipo de diretriz de configuração de parâmetros relevantes para estimular a capacidade de rendimento máxima do dispositivo em teste. A nota de aplicação descreve o estado mais atual das soluções de teste da Rohde & Schwarz no momento de sua elaboração. Os conjuntos de funcionalidades apresentados estão em constante evolução, portanto as capturas de tela e os parâmetros mostrados podem variar.
