Abstract

manuseio de erro em mudança automática de enlace ativo duplo. trata-se de métodos, sistemas e dispositivos para comunicações sem fio. em alguns sistemas, um equipamento de usuário (ue) pode realizar um procedimento de mudança automática de enlace ativo duplo de uma estação-base fonte para uma estação-base alvo. durante o procedimento de mudança automática de enlace ativo, o ue pode ter conexões com ambas as estações-base simultaneamente. em tais casos, as oportunidades de transmissão par se comunicar com as estações-base podem conflitar. para lidar com as oportunidades de transmissão conflitantes, o ue pode descartar uma ocasião de monitoramento ou um recebimento de pacote para uma estação-base com base nas regras de priorização. em alguns casos, para mitigar perdas de pacote, a estação-base pode configurar retransmissões ou agregação de partição para fornecer ao ue oportunidades adicionais para receber um pacote. adicional ou alternativamente, o ue pode transmitir uma mensagem de notificação para uma estação-base que indica ocasiões de monitoramento ou pacotes descartados.
