Title
(EN) SINGLE TRANSMITTER SWITCHING FOR DUAL CONNECTIVITY
(FR) COMMUTATION D'ÉMETTEUR UNIQUE POUR DOUBLE CONNECTIVITÉ
Abstract
(EN)
Methods, systems, and devices for wireless communications are described. In some cases, a user equipment (UE) may identify, for a carrier aggregation (CA) configuration including a primary cell and one or more secondary cells, a first frame structure configuration for the primary cell and a second frame structure configuration for a secondary cell of the one or more secondary cells. The UE may receive, from a base station, a downlink communication on the secondary cell. The UE may determine a feedback timing for the secondary cell based on the first frame structure configuration for the primary cell and the second frame structure configuration for the secondary cell. The UE may transmit, in response to the received downlink communication, feedback to the base station according to the feedback timing.

L’invention concerne des procédés, des systèmes et des dispositifs pour des communications sans fil. Dans certains cas, un équipement utilisateur (UE) peut identifier, pour une configuration d'agrégation de porteuses (CA) comprenant une cellule primaire et une ou plusieurs cellules secondaires, une première configuration de structure de cadre pour la cellule primaire et une seconde configuration de structure de cadre pour une cellule secondaire de la ou des cellules secondaires. L'UE peut recevoir, en provenance d'une station de base, une communication de liaison descendante sur la cellule secondaire. L'UE peut déterminer une temporisation de rétroaction pour la cellule secondaire sur la base de la première configuration de structure de cadre pour la cellule primaire et de la seconde configuration de structure de cadre pour la cellule secondaire. L'UE peut transmettre, en réponse à la communication de liaison descendante reçue, une rétroaction à la station de base en fonction de la temporisation de rétroaction.
