Title
(EN) TECHNIQUES FOR ASSISTED DOWNLINK HARQ FEEDBACK IN CARRIER AGGREGATION MODE
(FR) TECHNIQUES DE RÉTROACTION HARQ DE LIAISON DESCENDANTE ASSISTÉE DANS UN MODE D'AGRÉGATION DE PORTEUSES
Abstract
(EN) Methods, systems, and devices for wireless communications are described. The method includes transmitting, to a base station based on a parameter of a configuration of the UE, a first HARQ feedback configuration or a request to modify the configuration of the UE, or both, the configuration of the UE including a carrier aggregation configuration and receiving, from the base station based on transmitting the first HARQ feedback configuration or request to modify the configuration of the UE, or both, a second HARQ feedback configuration or reconfiguration.
(FR) L'invention concerne des procédés, des systèmes, et des dispositifs destinés aux communications sans fil. Le procédé consiste à transmettre, à une station de base sur la base d'un paramètre d'une configuration de l'UE, une première configuration de rétroaction HARQ ou une demande de modification de la configuration de l'UE, ou les deux, la configuration de l'UE comprenant une configuration d'agrégation de porteuses et à recevoir, de la station de base sur la base de la transmission de la première configuration de rétroaction HARQ ou de la demande de modification de la configuration de l'UE, ou des deux, une seconde configuration ou reconfiguration de rétroaction HARQ.
