Abstract

esquema de combinação harq para sistemas ofdm/ofdma um método e aparelho para a combinação de mensagens harq retransrnitidas em diferentes estágios em um receptor ofdm/ofdma são fornecidos. o tipo de cornbinador harq utilizado para um canal em particular pode depender de vários critérios de seleção incluindo a ordem de modulação da transmissão, o número de bits necessários para os sinais combinados, e o espaço no armazenador harq. para algumas modalidades, urna combinação de diferentes tipos de cornbinadores harq pode ser projetada em um receptor e selecionada por canal. a seleção adequada de um esquema de combinação harq pode reduzir o tamanho de armazenador harq necessário e pode fornecer um ganho de combinação aumentado quando comparado com as técnicas de combinação harq convencionais.
