Patent

CA 2708308

A system is disclosed for providing multimedia broadcast multicast services (MBMS) using a single cell point-to-multipoint (SC-PTM) communication. The system includes a processor configured to promote transmitting scheduling information for a multicast traffic channel (MTCH) related to an MBMS service onto a physical downlink control channel (PDCCH). In a first transmission, the scheduling information includes modulation and coding information related to the MBMS service. In a second transmission, the scheduling information includes an indicator instead of the modulation and coding information. The indicator related to the MBMS service and indicating to a user equipment to use the modulation and coding information in the first transmission for the MBMS service.

La présente invention concerne un système permettant de fournir des services de diffusion/multidiffusion multimédia (MBMS) à l'aide d'une communication point à multipoint à cellule unique (SC-PTM). Le système comprend un processeur conçu pour favoriser la transmission d'informations de planification pour un canal de trafic multidiffusion (MTCH) associé à un service MBMS sur un canal de commande de liaison descendante physique (PDCCH). Dans une première transmission, les informations de planification comprennent des informations de modulation et de codage associées au service MBMS. Dans une seconde transmission, les informations de planification comprennent un indicateur à la place des informations de modulation et de codage. L'indicateur est associé au service MBMS et indique à un équipement utilisateur d'utiliser les informations de modulation et de codage dans la première transmission pour le service MBMS.
