Abstract:
1. A communication apparatus, comprising: at least one user data communication block configured to transport user data, the user data communication block comprising two or more logical sub blocks configured to process user data on different protocol layers, wherein each of the sub blocks comprises a user data interface for outputting the user data to a sub block of an upper protocol layer and a sensing data interface for outputting sensing data to a spectrum sensing control block, and wherein the sensing data comprises at least one of: information about energy on a frequency band, a used radio technology, and a network or node identity; and wherein the spectrum sensing control block is configured to select at least one of the different protocol layers for providing spectrum sensing data, and to control, through the sensing data interface, spectrum sensing performed by at least one of the sub blocks corresponding to the selected at least one protocol layer and to receive the sensing data from the at least one of the sub blocks.
