Title
(EN) CONTENTION-BASED RESERVATIONS OF NETWORK RESOURCES
(FR) RÉSERVATIONS À BASE DE CONFLIT DE RESSOURCES RÉSEAU
Abstract
(EN)
In a wireless (e.g., machine-to-machine) network, items of user equipment compete for wireless communication resource slots ("resources"). In a contention period, an item of user equipment (a UE) sends a first signal to a base station using a first resource. The first resource is mapped to a second resource in a data transmission period. If the base station successfully receives the first signal, it sends a second signal to the UE to confirm that the UE has been awarded the second resource and can transmit data in the data transmission period.
(FR)
La présente invention concerne, dans un réseau sans fil (par exemple, machine-à-machine), des éléments d'équipement d'utilisateur qui sont en compétition pour des créneaux de ressources de communication sans fil (« ressources »). Dans une période de conflit, un élément d'équipement d'utilisateur (UE) envoie un premier signal à une station de base à l'aide d'une première ressource. La première ressource est mise en correspondance avec une seconde ressource dans une période de transmission de données. Si la station de base reçoit avec succès le premier signal, elle envoie un second signal à l'UE pour confirmer que l'UE s'est vu attribuer la seconde ressource et peut transmettre des données dans la période de transmission de données.
