Abstract

aspectos do assunto divulgado podem incluir, por exemplo, receber, por um elemento de rede de um sistema de antena distribuída, um sinal de referência, um canal de controle e um primeiro sinal modulado em uma primeira frequência portadora, o primeiro sinal modulado incluindo primeiros dados de comunicação fornecidos por uma estação de base e dirigidos a um dispositivo de comunicação móvel. as instruções no canal de controle dirigem o elemento de rede do sistema de antena distribuída para converter o primeiro sinal modulado na primeira frequência portadora para o primeiro sinal modulado em um primeiro segmento espectral. o sinal de referência é recebido em uma frequência dentro da banda relativa ao canal de controle. outras modalidades são divulgadas.aspects of the disclosed subject matter may include, for example, receiving, by a network element of a distributed antenna system, a reference signal, a control channel and a first modulated signal on a first carrier frequency, the first modulated signal including first communication data provided by a base station and directed to a mobile communication device. The instructions in the control channel direct the distributed antenna system network element to convert the first modulated signal at the first carrier frequency to the first modulated signal into a first spectral segment. The reference signal is received at a frequency within the band relative to the control channel. other modalities are disclosed.
