Title
(EN) PATHLOSS REFERENCE SIGNAL AND TRANSMISSION CONFIGURATION INDICATOR STATE ACTIVATION WITH SECONDARY CELL ACTIVATION
(FR) SIGNAL DE RÉFÉRENCE D'AFFAIBLISSEMENT DE CHEMIN ET ACTIVATION D'ÉTAT D'INDICATEUR DE CONFIGURATION DE TRANSMISSION AVEC ACTIVATION DE CELLULE SECONDAIRE
Abstract
(EN) Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station, a message that indicates a secondary cell (SCell) for activation. The UE may measure a reference signal on the SCell to estimate pathloss based at least in part on receiving the message and without receiving an additional message that indicates the reference signal for activation. Additionally, or alternatively, the UE may transmit or receive information on the SCell, using a transmission configuration indicator (TCI) state that is based at least in part on receiving the message, without receiving an additional message that indicates the TCI state for activation. Numerous other aspects are described.
(FR) Divers aspects de la présente divulgation concernent de manière générale les communications sans fil. Selon certains aspects, un équipement d'utilisateur (UE) peut recevoir, d'une station de base, un message qui indique une cellule secondaire (SCell) aux fins d'activation. L'UE peut mesurer un signal de référence sur la SCell pour estimer un affaiblissement de chemin sur la base au moins en partie de la réception du message et sans la réception d'un message supplémentaire qui indique le signal de référence aux fins d'activation. De plus, ou en variante, l'UE peut transmettre ou recevoir des informations sur la SCell, en utilisant un état d'indicateur de configuration de transmission (TCI) qui est basé au moins en partie sur la réception du message, sans la réception d'un message supplémentaire qui indique l'état TCI aux fins d'activation. La divulgation concerne également de nombreux autres aspects.
