Abstract

difusão em grupo de enlace lateral em bandas de frequência de ondas milimétricas. descrevem-se métodos, sistemas e dispositivos para comunicações sem fio. um equipamento de usuário (ue) pode ser configurado para realizar uma transmissão de difusão em grupo em um canal de enlace lateral de uma banda de alta frequência, tal como uma banda de ondas milimétricas (mmw). o ue pode transmitir, por meio de um canal de enlace lateral, repetições conformadas de feixe de um pacote em várias direções correspondentes a vários perfis de qualidade de serviço (qos) configurados para a transmissão do pacote. o ue pode determinar pré-codificadores para transmitir o pacote em várias direções. cada repetição do pacote pode ser associada a um processo separado de solicitação de repetição automática híbrida (harq). o ue pode executar o ciclo do pré-codificador para transmitir o pacote nas várias direções, e o ue pode retransmitir o pacote nas direções em que a transmissão inicial não foi bem-sucedida.
