Title (EN) COEXISTENCE ON UNLICENSED FREQUENCY BANDS USING ADAPTIVE CLEAR-TO-SEND-TO-SELF MESSAGES
(FR) COEXISTENCE SUR DES BANDES DE FRÉQUENCES SANS LICENCE À L'AIDE DE MESSAGES ADAPTATIFS "PRÊTS À ÉMETTRE À SOI-MÊME"
Abstract: front page image
(EN) A base station operates according to a first radio access technology (RAT) that requires synchronization on timing synchronization boundaries. The base station acquires a channel of an unlicensed frequency band and generates a clear-to-send message that is decodable by access points that operate according to a second RAT that does not require synchronization on the timing synchronization boundaries. The base station transmits the clear-to-send message during a time interval between acquisition of the channel and a subsequent timing synchronization boundary.
(FR) Une station de base fonctionne selon une première technologie d'accès radio (RAT, "radio access technology") qui nécessite une synchronisation sur les limites de synchronisation de temporisation. La station de base acquiert un canal d'une bande de fréquence sans licence et génère un message "prêt à émettre" qui est décodable par des points d'accès qui fonctionnent selon une seconde RAT qui ne nécessite pas de synchronisation sur les limites de synchronisation de temporisation. La station de base transmet le message "prêt à émettre" pendant un intervalle de temps entre l'acquisition du canal et une limite de synchronisation de temporisation ultérieure.
