DYNAMIC RECONFIGURATION OF REGULATION-COMPLIANCE MODE IN COGNITIVE RADIO NETWORKS

摘要

A method of dynamically reconfiguring the device's compliance-compliant mode, operating in network operating mode 311, 321, 322 in the spectrum band with the primary users, is provided. The method includes: providing a primary protection capability (510, 502, 704, 705) of the device, availability (601, 701) of an enabling signal for the device, and a frequency (508, 510, 711, 712) /RTI periodically; And operating and configuring transmission parameters of the device in accordance with one of a plurality of regulatory-compliance modes supported by the device, based on the results of such determinations. The wireless device includes: a signal transceiver (201) for processing, transmitting, and receiving wireless signals from the secondary devices; A primary signal detection module 202 for detecting a primary signal; A spectrum manager 204 for selecting or deselecting an operating frequency channel; And a geolocation module to detect the location of the device. The wireless device may further include a network interface (203) for accessing the TV band database and the geolocation database.;
