Title
(EN) NARROWBAND TIME-DIVISION DUPLEX FRAME STRUCTURE FOR NARROWBAND COMMUNICATIONS
(FR) STRUCTURE DE TRAME EN DUPLEX À RÉPARTITION DANS LE TEMPS À BANDE ÉTROITE POUR COMMUNICATIONS À BANDE ÉTROITE
Abstract
(EN) In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. In addition, the apparatus may determine a first set of subframes in the narrowband TDD frame structure used for transmitting a downlink control channel to a UE. In one aspect, a last subframe in the first set of subframes may be subframe n. Further, the apparatus may determine a second set of subframes in the narrowband TDD frame structure used for transmitting a downlink data channel to the UE. In certain aspects, a first subframe in the second set of subframes may be delayed based on k0 number of subframes after the subframe n. In certain other aspects, a last subframe in the second set of subframes may be subframe n + k0 + x. Additionally, the apparatus may signal first information associated with the k0 number of subframes to the UE in a first delay field in a DCI transmission.
(FR) Selon un mode de réalisation, l'invention concerne un procédé, un support lisible par ordinateur et un appareil. En outre, l'appareil peut déterminer un premier ensemble de sous-trames dans la structure de trame duplex à répartition dans le temps TDD à bande étroite utilisée pour la transmission d'un canal de commande de liaison descendante à un équipement UE utilisateur. Selon un aspect, une dernière sous-trame dans le premier ensemble de sous-trames peut être une sous-trame n. En outre, l'appareil peut déterminer un second ensemble de sous-trames dans la structure de trame TDD à bande étroite utilisée pour transmettre un canal de données de liaison descendante à l'UE. Selon certain aspects, une première sous-trame dans le second ensemble de sous-trames peut être retardée sur la base du nombre de sous-trames k 0 après la sous-trame n. Selon certains autres aspects, une dernière sous-trame dans le second ensemble de sous-trames peut être la sous-trame n + k 0 + x. En outre, l'appareil peut signaler des premières informations associées au nombre k 0 de sous-trames à l'équipement UE dans un premier champ de retard dans une transmission d'informations de commande de liaison descendante (DCI).
