Abstract

diversos aspectos aqui descritos referem-se a comunicações de repetição/solicitação automática híbrida (harq) em uma rede sem fio. uma primeira ocorrência de comunicação de harq é transmitida ou recebida através de um primeiro conjunto de um ou mais links. com base na transmissão ou recepção da primeira ocorrência da comunicação de harq, uma concessão de programação pode ser recebida para uma segunda ocorrência da comunicação de harq através de um segundo conjunto de um ou mais links diferente do primeiro conjunto de um ou mais links. a segunda ocorrência da comunicação de harq pode ser, por conseguinte, transmitida ou recebida através do segundo conjunto de um ou mais links com base, pelo menos em parte na concessão de programação.
