Abstract
(EN)
Methods, systems, and devices for wireless communications are described. A base station may implement cross-carrier scheduling. A user equipment (UE) may identify a minimum scheduling delay and may receive a downlink grant on a first CC. The UE may further identify the slot in which a downlink data transmission corresponding to the downlink grant will be received, and may identify the slot such that the minimum scheduling delay is satisfied. The UE may the receive the downlink data transmission, as indicated in the downlink grant, in the identified slot. In some examples, the UE and the base station may alternate between a long minimum scheduling delay and a short minimum scheduling delay. In some examples, the UE and the base station may alternate between a cross-carrier mode, and a self-scheduling mode.

L’invention concerne des procédés, des systèmes et des dispositifs pour les communications sans fil. Une station de base peut mettre en œuvre un ordonnancement inter-porteuses. Un équipement utilisateur (UE) peut identifier un retard d'ordonnancement minimum et peut recevoir une autorisation de liaison descendante sur une première CC. L'UE peut en outre identifier l'intervalle de temps pendant lequel une transmission de données de liaison descendante correspondant à l'autorisation de liaison descendante sera reçue, et peut identifier l'intervalle de temps de manière à garantir un retard d'ordonnancement minimal. L'UE peut recevoir la transmission de données de liaison descendante, comme indiqué dans l'autorisation de liaison descendante, pendant l'intervalle de temps identifié. Dans certains exemples, l'UE et la station de base peuvent alterner entre un long retard d'ordonnancement minimum et un court retard d'ordonnancement minimum. Dans certains exemples, l'UE et la station de base peuvent alterner entre un mode inter-porteuses et un mode d'auto-ordonnancement.
