Title
(EN) LONG TERM EVOLUTION-M RESOURCE RESERVATION USING BITMAP
(FR) RÉSERVATION DE RESSOURCE DE TECHNOLOGIE D'ÉVOLUTION À LONG TERME POUR LES MACHINES (M) À L'AIDE D'UNE TABLE DE BITS
Abstract
(EN)
A method and network node for flexible indication of resources in LTE-M using bitmaps are disclosed. According to one aspect, a method includes indicating to the wireless device a set of reserved resources for machine communications in compatibility with a broadband radio access technology sharing resources in a time frame and frequency band that encompasses the set of reserved resources, the indicating using a two level bitmap operating in the time-domain, a first bitmap level of the two level bitmap indicating a first set of subframes containing reserved resources, and a second bitmap level of the two level bitmap indicating reserved symbols within an indicated subframe.
(FR)
La présente invention concerne un procédé et un nœud de réseau pour une indication souple de ressources dans la technologie d'évolution à long terme pour les machines (LTE-M) à l'aide de tables de bits. Selon un aspect, un procédé consiste à indiquer au dispositif sans fil un ensemble de ressources réservées pour des communications de machine en compatibilité avec une technologie d'accès radio à large bande partageant des ressources dans une trame de temps et une bande de fréquences qui englobe l'ensemble de ressources réservées, l'indication utilisant une table de bits à deux niveaux fonctionnant dans le domaine temporel, un premier niveau de table de bits de la table de bits à deux niveaux indiquant un premier ensemble de sous-trames contenant des ressources réservées, et un second niveau de table de bits de la table de bits à deux niveaux indiquant des symboles réservés dans une sous-trame indiquée.
