SYSTEMS AND METHODS FOR DYNAMIC WHITESPACE SPECTRUM MANAGEMENT

摘要

SYSTEMS AND METHODS FOR DYNAMIC WHITE SPACE MANAGEMENT ARE DESCRIBED. FIRST, LOCAL HANDLING OF CHANNEL QUERIES (402, 420) IN WHICH A CHANNEL QUERY BY A WHITE SPACE DEVICE, WSD IS HANDLED BY A LOCAL DYNAMIC SPECTRUM MANAGEMENT, DSM SERVER, IF THE DSM SERVER HAS ALL THE INFORMATION NECESSARY FOR PROVIDING A RESPONSE TO THE CHANNEL QUERY (416, 426). SECOND, A SEARCH EXTENSION, IN WHICH A WSDB PASSES PART OF A SEARCH FOR AVAILABLE CHANNELS TO A LOCAL DSM SERVER (510). THIRD, ASSISTING OF AN AVAILABLE CHANNEL CALCULATION, IN WHICH A DSM SERVER PROVIDES SPECTRUM SENSING INFORMATION TO WSDBs (514) TO IMPROVE THE AVAILABLE CHANNEL CALCULATION WITHIN THE WSDBs. AND FOURTH, DYNAMIC BANDWIDTH MANAGEMENT TO MEET THE COEXISTENCE REQUIREMENTS. IN ADDITION, THE CONTENT OF THE MESSAGES AND PROCEDURES THAT ENABLE THE ABOVE VALUE-ADDING FUNCTIONS AND INTERACTIONS WITH THE WSDB SYSTEMS ARE DESCRIBED. THE MOST ILLUSTRATIVE DRAWING IS FIG. 3A.
