The present document defines an information model and protocol for generalized reconfigurable radio frequency interface for reconfigurable REs except for reconfigurable mobile devices which are covered in [i.7] to [i.12]. 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 will be based on ETSI EN 303 146-2 [i.10] and provide a generalized interface definition for the generalized Reconfigurable Radio Frequency Interface.
