Abstract

MÉTODO E DISPOSITIVO DE RETROALIMENTAÇÃO DE HARQ-ACK, TERMINAL E ESTAÇÃO-BASE. Trata-se de um método e dispositivo de retroalimentação de HARQ-ACK, um terminal e uma estação-base. O método aplicado ao terminal inclui: se um PDCCH que indica uma liberação de recurso de SPS for recebido em um intervalo para receber uma transmissão de PDSCH de SPS, mapear uma retroalimentação de HARQ-ACK do PDCCH que indica a liberação de recurso de SPS, para uma posição de retroalimentação determinada de acordo com um recurso de domínio de tempo de referência em uma sequência de retroalimentação de HARQ-ACK; transmitir a sequência de retroalimentação de HARQ-ACK que inclui a retroalimentação de HARQ-ACK do PDCCH que indica a liberação de recurso de SPS.
