Abstract
(EN)
Methods and systems of asynchronous access and synchronous transmission include transmitting an initial reservation packet using a first protocol to prevent other devices that use the first protocol from transmitting during a reserved duration. A carrier using a second protocol is activated. Information is transmitted using a second protocol during the reserved duration. During a last subframe of the reserved duration, an additional reservation packet is transmitted using the first protocol to extend the reserved duration. The transmission of the additional reservation packet takes place while the carrier using the second protocol is still active.

L'invention concerne des procédés et des systèmes d'accès asynchrone et de transmission synchrone qui comprennent la transmission d'un paquet de réservation initial à l'aide d'un premier protocole pour empêcher d'autres dispositifs qui utilisent le premier protocole de transmettre pendant une durée réservée. Une porteuse utilisant un second protocole est activée. Les informations sont transmises au moyen d'un second protocole pendant la durée réservée. Au cours d'une dernière sous-trame de la durée réservée, un paquet de réservation supplémentaire est transmis à l'aide du premier protocole de manière à prolonger la durée réservée. La transmission du paquet de réservation supplémentaire a lieu pendant que la porteuse utilisant le second protocole est toujours active.
