Abstract

trata-se de métodos, sistemas e dispositivos para comunicação sem fio. um equipamento de usuário (ue) ou uma estação de base podem identificar um parâmetro de avanço de temporização e um parâmetro de processamento para o ue, e um ou ambos podem determinar uma temporização de solicitação de repetição automática híbrida (harq) com base nos parâmetros identificados. por exemplo, se o ue tem um grande avanço de temporização ou capacidade de processamento reduzida, pode-se escolher uma temporização de harq mais longa. quando o ue receber transmissões em enlace descendente (dl) a partir da estação de base, o ue pode enviar uma confirmação (ack) ou uma confirmação negativa (nack) com base na temporização de harq escolhida. a estação de base pode enviar uma retransmissão (no caso de um nack) com base na temporização de harq. em alguns casos, o ue pode solicitar uma temporização de harq específica, ou solicitar um avanço de temporização atualizado. se a sincronização de harq for perdida, o ue e a estação de base podem predefinir uma temporização de harq pré-configurada.
