Abstract

La présente invention concerne un procédé et un dispositif de d'indication d'attribution de ressources, une station de base et un terminal. Le procédé est appliqué à une station de base sur la base d'une communication de type machine (MTC) et comprend les étapes consistant à : limiter la quantité d'attribution et/ou la position d'attribution d'un bloc de ressources physiques (PRB) dans une bande étroite attribuée par une station de base à un terminal ; déterminer le nombre de bits occupés par un domaine d'indication d'attribution de ressources de PRB dans des informations de commande de liaison descendante (DCI) en fonction de la quantité d'attribution et/ou de la position d'attribution ; et établir, sur la base du nombre de bits, une relation de mappage entre le domaine d'indication d'attribution de ressources de PRB et la quantité d'attribution et la position d'attribution du PRB dans la bande étroite. En utilisant le procédé dans le mode de réalisation de la présente invention, l'espace occupé par un domaine d'indication d'attribution de ressources de PRB dans des informations de commande de liaison descendante (DCI) peut être comprimé.
