Title (EN) APPARATUS AND METHOD FOR ENQUIRING CHANNEL CONDITION INFORMATION IN COGNITIVE RADIO WIRELESS COMMUNICATION SYSTEM
(FR) APPAREIL ET PROCÉDÉ DE DEMANDE D'INFORMATIONS D'ÉTAT DE CANAL DANS UN SYSTÈME DE COMMUNICATION SANS FIL DE RADIO COGNITIVE
Abstract: front page image
(EN)A method of operating a Data Base (DB) server for storing spectrum condition information on a licensed system in a Cognitive Radio (CR)-based wireless communication system and a CR-based wireless communication system are provided. The method includes determining changes in the spectrum condition information on the licensed system, recalculating maximum Equivalent Isotropically Radiated Power (EIRP) allowed for each channel of CR-based devices registered in a list, and transmitting information regarding the recalculated maximum allowed EIRP.
(FR)L'invention concerne un procédé de fonctionnement d'un serveur de base de données (DB) destiné à stocker des informations d'état de spectre sur un système autorisé sous licence dans un système de communication sans fil à base de radio cognitive (CR) et un système de communication sans fil à base de CR. Le procédé consiste à déterminer des changements dans les informations d'état de spectre sur le système autorisé sous licence, à recalculer une puissance rayonnée de manière isotrope équivalente ( EIRP) maximum autorisée pour chaque canal de dispositifs à base de CR enregistré dans une liste, et à émettre les informations relatives à l'EIRP autorisée maximum recalculée.
