Abstract

Aspects of the subject disclosure may include, for example, a wireless communication node that receives instructions in a control channel directing it to utilize a spectral segment at a first carrier frequency to communicate with a mobile communication device. Responsive to the instructions, the wireless communication node receives a modulated signal in the spectral segment at a second carrier frequency from the base station, the modulated signal including communications data provided by the base station. The wireless communication node down-shifts the modulated signal at the second carrier frequency to the first carrier frequency, and wirelessly transmits the modulated signal at the first carrier frequency to the mobile communication device. Other embodiments are disclosed.
