Abstract

L'invention concerne un procédé de détermination, au niveau d'un réseau, d'un retard de commutation d'état d'un indicateur de configuration de transmission (TCI) de liaison descendante (DL) pour un équipement utilisateur (UE) dans la gamme de fréquences 2 (FR2). Le procédé comprend la réception d'un message de capacité d'UE en provenance de l'UE indiquant que l'UE : est apte à prendre en charge deux avances temporelles (TA) ; est apte à prendre en charge une différence temporelle de réception (RTD) supérieure à un préfixe cyclique (CP) ; et n'est pas en mesure d'assurer une réception (Rx) de liaison descendante (DL) multi-réception dans FR2. Le procédé comprend l'ajout d'un retard supplémentaire d'une période de bloc de signal de synchronisation (SSB) à un retard de commutation d'état TCI DL pour tenir compte de blocs de signal de synchronisation (SSB) chevauchants ou adjacents transmis indépendamment par des points d'émission et de réception multiples (mTRP). Le retard de commutation d'état TCI DL est pour des informations de commande de liaison descendante multiple (mDCI) mTRP et un TCI unifié étendu (eUTCI). Le procédé comprend l'envoi du retard de commutation d'état TCI DL pour sa transmission à l'UE par l'intermédiaire d'une station de base.
