The present document defines an information model and protocol for multiradio interface for reconfigurable RE except for reconfigurable mobile devices which are covered in [i.6] to [i.11]. The work is based on the Use Cases defined in ETSI TR 103 585 [i.1], on the system requirements defined in ETSI EN 303 641 [1] and on the radio reconfiguration related architecture for reconfigurable RE defined in ETSI EN 303 648 [i.2]. The present document is based on ETSI EN 303 146-1 [i.8] and provide a generalized interface definition for the generalized Software Reconfiguration Architecture.
