Abstract
(EN)
Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a downlink control message (e.g., via a physical downlink control channel (PDCCH)) from a first transmission reception point (TRP) including a transmission configuration indicator (TCI) state identifying multiple quasi co-location (QCL) relationships for the UE. The UE may determine a first set of control parameters for communication with the first TRP and a second set of control parameters for communication with a second TRP based on the downlink control message. In some cases, the second set of control parameters may be different than first set of control parameters. The UE may communicate with the first TRP and the second TRP (e.g., the UE may receive a physical downlink shared channel (PDSCH) from each TRP) based on the first set of control parameters and the second set of parameters.

L’invention concerne des procédés, des systèmes et des dispositifs de communication sans fil. Un équipement utilisateur (UE) peut recevoir un message de commande de liaison descendante (par exemple, par l'intermédiaire d'un canal de commande de liaison descendante physique (PDCCH)) à partir d'un premier point de réception de transmission (TRP) comprenant un état d'indicateur de configuration de transmission (TCI) identifiant de multiples relations de quasi co-emplacement (QCL) pour l'UE. L'UE peut déterminer un premier ensemble de paramètres de commande pour une communication avec le premier TRP et un second ensemble de paramètres de commande pour une communication avec un second TRP sur la base du message de commande de liaison descendante. Dans certains cas, le second ensemble de paramètres de commande peut être différent du premier ensemble de paramètres de commande. L'UE peut communiquer avec le premier TRP et le second TRP (par exemple, l'UE peut recevoir un canal partagé de liaison descendante physique (PDSCH) à partir de chaque TRP) sur la base du premier ensemble de paramètres de commande et du second ensemble de paramètres.
