Title
(EN) ATSC 3.0 PHYSICAL LAYER EXTENSIONS TO ENABLE MOBILITY BROADCAST 5G CONVERGENCE
(FR) EXTENSIONS DE COUCHE PHYSIQUE ATSC 3.0 POUR PERMETTRE UNE CONVERGENCE DIFFUSION/5G EN MOBILITÉ
Abstract
(EN)
The ATSC 3.0 physical layer broadcast standard is extended with new OFDM numerology, L1 signaling and frame structure aligned with 5G. This is done to enable improved broadcast mobility and convergence 5G release 16 as a Non-3GPP access network. The 5G core network and Broadcast core network interwork over defined interfaces to enable convergence layer 3. This enables improvements of broadcast physical layer for physics of broadcast. The 5G unicast physical layer is enhanced for physics of unicast, and then both are converged at layer 3. This is novel and has many benefits compared to the legacy LTE broadcast method (e.g., Evolved Multimedia Broadcast Multicast Services (eMBMS)), which combines both broadcast and unicast into a single shared LTE frame at layer 1. The eMBMS method is then improved for dominate unicast mode in shared L1 frame. The result is the broadcast performance and efficiency in eMBMS are less than optimal.

Selon l'invention, la norme de diffusion de couche physique ATSC 3.0 est étendue avec une numérologie OFDM, une signalisation L1 et une structure de trame nouvelles alignées avec la 5G. Ceci est effectué pour permettre une meilleure mobilité de diffusion et une convergence avec la 5G version 16 en tant que réseau d'accès non 3GPP. Le cœur de réseau 5G et le cœur de réseau de diffusion interfonctionnent sur des interfaces définies pour activer la couche 3 de convergence. Cela permet des améliorations de la couche physique de diffusion pour la physique de la diffusion. La couche physique de monodiffusion 5G est améliorée pour la physique de la monodiffusion, puis on fait converger les deux au niveau de la couche 3. Ceci est nouveau et offre de nombreux avantages par comparaison au procédé de diffusion LTE patrimonial (par exemple, des services de diffusion/multidiffusion multimédia évolués (eMBMS)), qui combine la diffusion et la monodiffusion en une seule trame LTE partagée au niveau de la couche 1 (L1). Le procédé eMBMS est ensuite amélioré pour dominer le mode de monodiffusion dans la trame L1 partagée. Le résultat est que les performances et l'efficacité de diffusion dans eMBMS sont moins qu'optimales.
