Communication apparatus, communication method, and communication system
A wireless communication system, method and apparatus cooperate to use a wireless coordination signal from a control station in a first frequency band to establish direct links in a second frequency band between different terminals. Once established, the direct links in the second frequency band operate without further needing intervention by the control station. The first frequency band is 1 GHz or higher, and the second frequency band is at a higher frequency than the first frequency band.
