Abstract

método, dispositivo sem fio e estação-base para definir temporização de solicitação de repetição automática híbrida. métodos e sistemas para definir a temporização de solicitação de repetição automática híbrida (harq) para canal compartilhado de enlace descendente físico (pdsch) com um indicador de temporização de pdsch para harq pendente (phti) são fornecidos. em um aspecto, um método realizado por um dispositivo sem fio compreende: receber uma primeira informação de controle de enlace descendente (dci) associada a uma primeira transmissão de dados de enlace descendente (dl), sendo que a primeira dci compreende um phti não numérico; receber a primeira transmissão de dados de dl; determinar um retorno de harq para a primeira transmissão de dados de dl; receber uma segunda dci associada a uma segunda transmissão de dados de dl, sendo que a segunda dci compreende um phti numérico que indica um local para retorno de harq associado à segunda transmissão de dados de dl; definir que o local de retorno de harq associado à primeira transmissão de dados de dl seja o mesmo que o local de retorno de harq associado à segunda transmissão de dados de dl e transmitir o retorno de harq associado à primeira transmissão de dados de dl no local definido.
