(EN) RATE MATCHING FOR A DOWNLINK TRANSMISSION WITH MULTIPLE TRANSMISSION CONFIGURATIONS
(FR) MISE EN CORRESPONDANCE DE DÉBIT DESTINÉE À UNE TRANSMISSION DE LIAISON DESCENDANTE PRÉSENTANT PLUSIEURS CONFIGURATIONS DE TRANSMISSION
Abstract
(EN)
Certain aspects of the present disclosure provide techniques for rate-matching for a transmission by multiple transmission configuration indicator (TCI) states, such as a multiple transmission reception point (multi-TRP) transmission. A method by a user equipment (UE) includes receiving one downlink control information (DCI) scheduling a downlink transmission associated with multiple transmission configuration indicator (TCI) states. The UE determines whether the downlink transmission is associated with one rate matching or is associated with a separate rate matching for each of the multiple TCI states. The UE derate matches the downlink transmission based on the determination.

Certains aspects de la présente invention concernent des techniques de mise en correspondance de débit destinées à une transmission par l’intermédiaire de plusieurs états d'indicateur de configuration de transmission (TCI), tels qu'une transmission à points de réception de transmission multiples (multi-TRP). Un procédé par l'intermédiaire d'un équipement utilisateur (UE) consiste à recevoir une information de commande de liaison descendante (DCI) programmant une transmission de liaison descendante associée à plusieurs états d'indicateur de configuration de transmission (TCI). L'UE détermine si la transmission de liaison descendante est associée à une mise en correspondance de débit ou est associée à une mise en correspondance de débit distincte correspondant à chacun des multiples états TCI. La réduction de débit de l'UE correspond à la transmission de liaison descendante sur la base de la détermination.
