Title
(EN) BEAM SWITCHING BASED ON DCI INDICATION FOR MULTI-TRP URLLC
(FR) COMMUTATION DE FAISCEAU BASÉE SUR UNE INDICATION DE DCI POUR URLLC MULTI-TRP
Abstract
(EN)
Embodiments are directed to beam switching. An embodiment of a user equipment (UE) comprises a processor to configure the UE to receive, one or more repetitions of a transport block (TB) using a first physical downlink shared channel (PDSCH) beam, obtain a downlink control information (DCI) comprising one or more transmission configuration indicator (TCI) states, and configure the UE to switch from the first PDSCH beam to a second PDSCH beam, different from the first PDSCH beam, based at least in part on the one or more TCI states.
(FR)
Des modes de réalisation concernent la commutation de faisceau. Un mode de réalisation d'un équipement utilisateur (UE) comprend un processeur servant à configurer l'UE pour recevoir une ou plusieurs répétitions d'un bloc de transport (TB) à l'aide d'un premier faisceau de canal partagé de liaison descendante physique (PDSCH), obtenir des informations de commande de liaison descendante (DCI) comprenant un ou plusieurs états d'indicateur de configuration de transmission (TCI), et configurer l'UE pour commuter du premier faisceau PDSCH à un second faisceau PDSCH, différent du premier faisceau PDSCH, sur la base, au moins en partie, du ou des états de TCI.
