Abstract

?cabeça de rádio remota melhorada (errh) e dispositivo para alcançar compactação de front-haul em uma rede de acesso de rádio com base em nuvem (c-ran)? trata-se de sistemas e métodos revelados no presente documento que descrevem uma arquitetura de ran com base em nuvem de processamento centralizado (c-ran ou ran em nuvem) que oferece exigências de taxa de dados de front-haul reduzidas em comparação às arquiteturas de c-ran com base em interface de rádio pública comum (cpri). o processamento de camada física de banda-base pode ser dividido entre um agrupamento de bbu e uma rrh melhorada (errh). uma abordagem de compactação de domínio de frequência que explora redundância de sinal de lte e informações de agendamento de usuário pode ser usada na errh para reduzir significativamente exigências de taxa de dados de front-haul. a quantização escalar uniforme e codificação de huffman de taxa variável no domínio de frequência podem ser aplicadas em uma abordagem de compactação com base nas informações de agendamento de usuário em que uma compactação com perda é seguida por uma compactação sem perda.
