This paper discusses the spectrum solutions of cognitive radios with a signaling channel. The scheme, which has a simple structure, could provide not only effective spectrum allocation, but also powerful spectrum management. The aim is to introduce solutions which can support different bandwidths for a large number of consumers and at the cost of simple modifications on the same hardware platform. Such structures have previously been used for mobile communication systems and the paper aims to discuss their possible applications in the context of cognitive radios. The solutions have excellent reliability, and might make the best of licensed spectrum.
