Title
(EN) DOWNLINK HYBRID AUTOMATIC REPEAT REQUEST FEEDBACK FOR NARROWBAND INTERNET OF THINGS DEVICES
(FR) RÉTROACTION D'UNE DEMANDE AUTOMATIQUE DE RÉPÉTITION HYBRIDE DE LIAISON DESCENDANTE POUR DES DISPOSITIFS DE L'INTERNET DES OBJETS À BANDE ÉTROITE
Abstract
(EN) Techniques for transmitting hybrid automatic repeat request (HARQ) feedback by narrowband Internet-of-Things (NB-IoT) devices are provided. NB-IoT user equipment (UE) can transmit HARQ feedback in response to a narrowband physical downlink shared channel (NPDSCH) received over a downlink (DL). NB-IoT UEs can transmit the responsive HARQ feedback over a narrowband physical uplink shared channel (NPUSCH) or a narrowband physical uplink control channel (NPUCCH). Options for defining the physical structures of the NPUCCH and NPUSCH and user multiplexing on the uplink (UL) are provided. Determination of an UL resource allocation by determining resources in time, frequency, and the code domain for the HARQ feedback transmissions are also provided. Higher level signaling and/or indications provided in downlink control information (DCI) can be used to determine the time, frequency, or code domain resources.
(FR) La présente invention concerne des techniques pour transmettre une rétroaction d'une demande automatique de répétition hybride (HARQ) par des dispositif de l'Internet des objets à bande étroite (NB-IoT). Un équipement utilisateur (UE) NB-IoT peut transmettre une rétroaction HARQ en réponse à un canal partagé de liaison descendante physique à bande étroite (NPDSCH) reçu sur une liaison descendante (DL). Des UE NB-IoT peuvent transmettre la rétroaction HARQ de réponse sur un canal partagé de liaison montante physique à bande étroite (NPUSCH) ou un canal de commande de liaison montante physique à bande étroite (NPUCCH). Des options pour définir les structures physiques des NPUCCH et NPUSCH et un multiplexage d'utilisateur sur la liaison montante (UL) sont fournies. La détermination d'une allocation de ressources UL en déterminant des ressources dans le domaine temporel, fréquentiel, et de code pour les transmissions de rétroaction HARQ est également effectuée. Une signalisation de niveau supérieur et/ou des indications fournies dans les informations de commande de liaison descendante (DCI) peuvent être utilisées pour déterminer les ressources de domaine temporel, fréquentiel ou de code.
