Title
(EN) METHOD AND APPARATUS FOR MULTIPLE TRANSMIT/RECEIVE POINT (TRP) OPERATIONS
(FR) PROCÉDÉ ET APPAREIL POUR DES OPÉRATIONS DE MULTIPLES POINTS D'ÉMISSION/RÉCEPTION (TRP)
Abstract
(EN)
A method includes receiving, by a User Equipment (UE), Transmission Configuration Indicator (TCI) state data in a Physical Download Control Channel (PDCCH) determining multiple Physical Downlink Shared Channels (PDSCHs), where the TCI state data is associated with multiple Demodulation Reference Signal (DMRS) port groups, and obtaining, by the UE, multiple Quasi Co-Location (QCL) assumptions for receiving the PDSCHs based on the DMRS port groups associated with the TCI state data.
(FR)
L'invention porte sur un procédé qui consiste à recevoir, par un équipement utilisateur (UE), des données d'état d'indicateur de configuration de transmission (TCI) dans un canal de commande de liaison descendante physique (PDCCH) déterminant de multiples canaux partagés de liaison descendante physiques (PDSCH), les données d'état TCI étant associées à de multiples groupes de ports de signal de référence de démodulation (DMRS), et à obtenir, par l'UE, de multiples hypothèses de quasi-colocalisation (QCL) pour recevoir les PDSCH sur la base des groupes de ports DMRS associés aux données d'état TCI.
