Summary:Provided is a method of transmitting frequency channel information by a device to which a frequency band is allocated so as to implement frequency sharing without affecting primary services. The method includes: modulating a stream having content into a main signal; generating a channel information signal related to the frequency band allocated to the device; and combining and transmitting the modulated main signal and the channel information signal. Accordingly, frequency sharing can be used for various primary services by enabling a terminal device to obtain information on a used frequency band without increasing the complexity of the terminal device. La présente invention concerne un procédé de transmission d'informations d'un canal de fréquence par un dispositif auquel est attribuée une bande de fréquence, de façon à mettre en place un partage de fréquence sans affecter les services primaires. Le procédé consiste à : moduler un flux possédant un contenu en un signal principal; générer un signal d'informations de canal lié à la bande de fréquence attribuée au dispositif; et combiner et transmettre le signal principal modulé et le signal d'informations de canal. Par conséquent, le partage de fréquence peut être utilisé pour de nombreux services primaires en permettant à un dispositif terminal d'obtenir des informations sur une bande de fréquence utilisée sans augmenter la complexité du dispositif terminal.
