The scope of the present document is to define the generalized Radio Programming Interface (gRPI) for radio equipment reconfiguration except for reconfigurable mobile devices which are covered in [i.4] to [i.9]. 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 radio equipment defined in ETSI EN 303 648 [i.2]. The present document will be based on ETSI EN 303 146-4 [i.9] and provide a generalized interface definition for the generalized Radio Programming Interface (gRPI).
