Abstract

retorno de confirmação para várias configurações de programação semipersistentes de downlink ativo. métodos, sistemas, e dispositivos para comunicações sem fio são descritos. uma estação base pode configurar recursos de uplink dentro de uma partição para permitir que um equipamento de usuário (ue) transmita uma mensagem de retorno de confirmação (ack) para várias configurações de programação semipersistente de downlink (sps). por exemplo, a estação base pode transmitir uma configuração adicional para o ue que indica recursos de uplink que o ue pode usar para transmitir retornos de confirmação para várias mensagens de downlink recebidas de acordo com as configurações de sps, onde o ue determina qual recurso de uplink usar com base em vários bits de informação de confirmação a serem transmitidos para a mensagem de retorno de confirmação. por exemplo, se o número de bits de informação de confirmação estiver abaixo de um valor limite, o ue pode usar um primeiro recurso de uplink configurado pela estação base. alternativamente, se o número de bits de informação de confirmação estiver acima do valor limite, o ue pode usar um segundo recurso de uplink.
