"The present document outlines the Use Cases which are related to the introduction of mechanisms to enable@ for reconfigurable radio systems@ the dynamic reconfiguration of equipment and its continuing conformity with the applicable legislation. These Use Cases involve the dynamic reconfiguration of reconfigurable radio equipment after its initial Declaration of Conformity and deployment. Such post-deployment reconfiguration will ensure the continued conformity in the new configuration to the applicable legislation. In some Use Cases@ new mechanisms that enable reconfigurable devices to have their Declaration of Conformity dynamically verified may be introduced. Note that the term ""Declaration of Conformity"" is typically used in conjunction with the European Radio Equipment Directive. In other regulation domains@ other terminology may be employed. While the Use Cases presented in the present document are designed to support the novel radio reconfiguration features of the Radio Equipment Directive [i.3] that is applicable in Europe@ the principles and the Use Cases outlined here are not limited to Europe and may also be appropriate for other regions."
