Abstract

MÉTODO E APARELHO DE PROCESSAMENTO DE TRANSMISSÃO DE SINAL E ESTAÇÃO BASE DISTRIBUÍDA. A presente invenção refere-se a um método e aparelho de processamento de transmissão de sinal e uma estação base distribuída, que são proporcionados, de acordo com as concretizações da presente invenção. A estação base distribuída inclui uma Unidade de Banda Base (BBU) e uma Unidade de Rádio Remota (RRU). pelo menos um canal de sinais de interface de uma estação base distribuída que são enviados por uma dentre a BBU e a RRU são obtidos: então é executada a multiplexação de camada elétrica de rede ótica de transporte (OTN) através do encapsulamento para gerar quadros de sinal OTN; e executando a conversão eletro-ótico, para gerar um canal de sinais óticos e transmitir os sinais óticos. No lado da outra dentre a BBU e a RRU, os sinais óticos são recebidos e os sinais de interface no mesmo são recuperados e então enviados para outra BBU e RRU. A presente invenção pode melhorar a eficiência da transmissão de sinal.
