Abstract[English]
Methods and systems for applying a transmission configuration indicator (TCI) state when a user equipment (UE) switches serving cells is provided. For example, the UE receives, from a first serving cell, an indication to switch connection to a second serving cell. The UE receives a set of radio resource control (RRC) configurations and a first TCI state for switching to a second serving cell. The UE switches connection from the first serving cell to the second serving cell based on the RRC configurations and applies the first TCI state on reception or transmission channels of the second serving cell. In some embodiments, the UE is configured to operate a Level1/Level 2 inter-cell handover. In some embodiments, when the handover condition is met, the UE performs handover with a physical cell ID to a serving cell and determines a TCI state for receiving downlink channels/RS and/or transmitting uplink channel/RS after handover.[French]
L'invention concerne des procédés et des systèmes pour appliquer un état d'indicateur de configuration de transmission (TCI) lorsqu'un équipement utilisateur (UE) commute des cellules de desserte. Par exemple, l'UE reçoit, d'une première cellule de desserte, une indication de commutation de connexion à une seconde cellule de desserte. L'UE reçoit un ensemble de configurations de commande de ressources radio (RRC) et un premier état d'indicateur TCI pour commuter vers une seconde cellule de desserte. L'UE commute la connexion de la première cellule de desserte à la seconde cellule de desserte sur la base des configurations de commande RRC et applique le premier état d'indicateur TCI sur des canaux de réception ou de transmission de la seconde cellule de desserte. Dans certains modes de réalisation, l'UE est configuré pour faire fonctionner un transfert intercellulaire de niveau 1/niveau 2. Dans certains modes de réalisation, lorsque la condition de transfert intercellulaire est remplie, l'UE effectue un transfert intercellulaire avec un ID de cellule physique vers une cellule de desserte et détermine un état d'indicateur TCI pour recevoir des canaux de liaison descendante/RS et/ou transmettre un canal de liaison montante/RS après le transfert intercellulaire.
