Abstract

MÉTODO DE RETROALIMENTAÇÃO DE HARQ-ACK, TERMINAL E ESTAÇÃO-BASE. São fornecidos um método de retroalimentação de confirmação (HARQ-ACK) de solicitação de repetição automática híbrida, um terminal e uma estação-base. O método compreende: receber sinalização de agendamento de difusão seletiva enviada por uma estação-base, e determinar um recurso de enlace ascendente correspondente à difusão ponto a ponto; e, quando for detectado que uma condição preestabelecida é satisfeita, multiplexar um primeiro livro de códigos de HARQ-ACK correspondente à sinalização de agendamento de difusão seletiva no recurso de enlace ascendente correspondente à difusão ponto a ponto, em que a condição preestabelecida é que um slot de tempo de retroalimentação de HARQ-ACK indicado pela sinalização de agendamento de difusão seletiva e um slot de tempo em que o recurso de enlace ascendente está localizado existem em uma janela preestabelecida no mesmo tempo. Nas modalidades da presente invenção, o projeto e a complexidade do protocolo HARQ-ACK para retroalimentação de difusão seletiva são simplificados.
