Abstract

MÉTODO PARA RETROALIMENTAÇÃO DE INFORMAÇÕES, TERMINAL E DISPOSITIVO DE REDE. Um método para retroalimentação de informações e dispositivos relacionados são revelados nas modalidades deste pedido. O método inclui o disposto a seguir. Um terminal recebe informações predefinidas de um dispositivo de rede, em que as informações predefinidas incluem pelo menos informações de transmissão ponto a multiponto (PTM). O terminal retroalimenta informações de resposta HARQ das informações predefinidas para o dispositivo de rede, em que informações de resposta HARQ incluem informações de resposta HARQ das informações de transmissão PTM. Pode-se observar que, na revelação, existe um mecanismo de retroalimentação HARQ quando o terminal recebe informações de transmissão PTM. Quando os dados de serviço de transmissão PTM são perdidos, o dispositivo de rede pode determinar se uma retransmissão precisa ser transmitida de acordo com as informações de retroalimentação HARQ, o que é benéfico para garantir a confiabilidade da transmissão de dados de serviço.
