Abstract

MÉTODO E APARELHO PARA COMUNICAÇÃO DE MULTICAST. Várias modalidades da presente divulgação proveem um método para comunicação de multicast. O método que pode ser desempenhado por um dispositivo terminal compreende receber um primeiro canal de enlace descendente incluindo um primeiro índice de atribuição de enlace descendente a partir de um nó de rede. O primeiro canal de enlace descendente é associado a um primeiro tráfego do dispositivo terminal. O método compreende adicionalmente determinar que o primeiro índice de atribuição de enlace descendente seja para o primeiro tráfego, de acordo com a associação entre o primeiro canal de enlace descendente e o primeiro tráfego. De acordo com várias modalidades da presente divulgação, a realimentação de solicitação de repetição automática híbrida pode ser implementada de maneira eficiente e flexível para diferentes tráfegos tais como tráfegos de multicast e unicast.
