Abstract

L'invention concerne un procédé et un dispositif de transmission de données dans une bande de garde à duplex temporel (TDD), associés au domaine des communications radio, à utiliser pour mettre en place une transmission de données dans une bande de garde à TDD, dans la mesure où la génération d'interférences est évitée autant que possible entre les trames secondaires en liaison montante/descendante dans la bande de garde à TDD et les trames secondaires en liaison montante/descendante dans les bandes adjacentes, ce qui augmente le taux d'utilisation du spectre. Dans la présente invention, la transmission de données est réalisée sur la bande de garde à TDD selon une structure de trames secondaires de transmission satisfaisant les critères suivants : dans une trame radio, une première trame secondaire et une sixième trame secondaire sont des trames secondaires en liaison descendante classiques, une deuxième trame secondaire est soit une trame secondaire spéciale soit une trame secondaire en liaison descendante tronquée, une troisième trame secondaire est soit une trame secondaire en liaison montante soit une trame secondaire vacante, une quatrième trame secondaire et une cinquième trame secondaire sont des trames secondaires vacantes, une septième trame secondaire est soit une trame secondaire spéciale soit une trame secondaire classique soit une trame secondaire en liaison descendante tronquée, une huitième trame secondaire est soit une trame secondaire vacante soit une trame secondaire en liaison descendante classique soit une trame secondaire en liaison descendante et la neuvième trame secondaire et la dixième trame secondaire sont soit des trames secondaires en liaison descendante classiques soit des trames secondaires vacantes.
