Title (EN) METHOD AND APPARATUS FOR REUSE OF WAN INFRASTRUCTURE RESOURCES IN A WIRELESS PEER-TO-PEER (P2P) NETWORK
(FR) PROCÉDÉ ET APPAREIL PERMETTANT DE RÉUTILISER DES RESSOURCES D'UNE INFRASTRUCTURE DE RÉSEAU ÉTENDU DANS UN RÉSEAU ENTRE HOMOLOGUES SANS FIL (P2P)
Abstract:
(EN) To make efficient use of a frequency spectrum, a peer-to-peer network shares a wide area network (WAN) frequency spectrum as well as a time-frequency structure of the WAN, where the time-frequency structure includes a set of tones and symbols of an OFDM system. A first wireless terminal monitors the time-frequency structure of the WAN to determine which subsets of tone-symbols are unused for WAN and/or other peer-to-peer connections. Then, the first wireless terminal selects and uses an unused subset of tone-symbols within the time-frequency structure for its peer-to-peer connection with a second wireless terminal..
(FR) Afin d'utiliser efficacement un spectre de fréquences, un réseau entre homologues partage un spectre de fréquences de réseau étendu (RE) ainsi qu'une structure temps-fréquence du RE, ladite structure temps-fréquence comprenant un ensemble de tonalités et de symboles d'un système MROF. Un premier terminal sans fil surveille la structure temps-fréquence du RE afin de déterminer les sous-ensembles de tonalités-symboles qui sont inutilisés pour le RE et/ou d'autres connexions entre homologues. Ensuite le premier terminal sans fil sélectionne et utilise un sous-ensemble inutilisé de tonalités-symboles dans la structure temps-fréquence pour sa connexion entre homologues avec un second terminal sans fil.
