Title (EN) COMMUNICATION SYSTEM
(FR) SYSTÈME DE COMMUNICATION
Abstract:
(EN) A communication system is disclosed in which a base station communicates with machine-type-communication (MTC) devices by dividing the base station's cell bandwidth into (non-overlapping) narrowbands and subframes in each narrowband. The base station generates and transmits control information (DCI) for allocating a set of physical resource blocks (PRBs) in a plurality of subframes for an MTC device. After the base station transmits the data, the MTC device generates and transmits an HARQ feedback indicating that i) the data has been successfully received in each one of the plurality of subframes (e.g. a single 'ACK') or ii) the data has not been received in at least one of the plurality of subframes (e.g. a single 'NACK').
(FR) L'invention concerne un système de communication dans lequel une station de base communique avec des dispositifs de communication de type machine (MTC), en divisant la largeur de bande de cellule de la station de base en bandes étroites (non chevauchantes) et en sous-trames dans chaque bande étroite. La station de base génère et transmet des informations de commande (DCI) pour attribuer un ensemble de blocs de ressources physiques (PRB) dans une pluralité de sous-trames pour un dispositif MTC. Une fois que la station de base transmet les données, le dispositif MTC génère et transmet une rétroaction HARQ indiquant que i) les données ont été reçues avec succès dans chacune de la pluralité de sous-trames (par exemple un 'ACK' unique) ou ii) les données n'ont pas été reçues dans au moins l'une de la pluralité de sous-trames (par exemple un 'NACK' unique).
