Title
(EN) FACILITATING AN ANTENNA PORT SPECIFIC DOWNLINK CONTROL CHANNEL DESIGN FOR ADVANCED NETWORKS
(FR) FACILITATION D'UNE CONCEPTION DE CANAL DE COMMANDE DE LIAISON DESCENDANTE SPÉCIFIQUE À UN PORT D'ANTENNE POUR DES RÉSEAUX AVANCÉS
Abstract
(EN)
Facilitating port specific downlink control channel design for advanced networks (e.g., 4G, 5G, and beyond) is provided herein. Operations of a system can comprise receiving a first indication related to a quantity of demodulation reference signal ports and a second indication related to a code division multiplexing group associated with a mobile device. The operations can also comprise, based on the code division multiplexing group and the demodulation reference signal ports, facilitating a transmission of an adaptive downlink control channel structure of a downlink control channel that comprises a demodulation reference signal sequence initialization.
(FR)
La présente invention concerne la facilitation d'une conception de canal de commande de liaison descendante spécifique à un port pour des réseaux avancés (par exemple, 4G, 5G et au-delà). Des opérations d'un système peuvent consister à recevoir une première indication relative à une quantité de ports de signal de référence de démodulation et une seconde indication relative à un groupe de multiplexage par répartition de code associé à un dispositif mobile. Les opérations peuvent également consister, sur la base du groupe de multiplexage par répartition de code et des ports de signal de référence de démodulation, à faciliter une transmission d'une structure de canal de commande de liaison descendante adaptative d'un canal de commande de liaison descendante qui comprend une initialisation de séquence de signal de référence de démodulation.
