Abstract

1/1 resumo "retorno para melhorar a previsão de taxa com interferência de rajada" quando um ue não decodifica completamente um pacote transmitido a partir de uma estação base, o ue pode enviar ack/nack para a estação base, depois do que a estação base pode retransmitir o pacote com base em ack/nack. no entanto, ack/nack falha em fornecer à estação base informação necessária pelo ue para decodificar completamente o pacote. de acordo, um método, um aparelho e um produto de programa de computador para comunicação sem fio são fornecidos. o aparelho recebe um pacote de uma estação base possuindo um primeiro mcs, determina a informação para fornecer para a estação base, onde a informação compreende a cqi referente a uma condição de canal e/ou condição de interferência correspondendo aos recursos de tempo e frequência alocados para o pacote recebido, e envia a informação para a estação base. depois disso, o aparelho recebe novamente o pacote da estação base, o pacote recebido novamente possuindo um segundo mcs de acordo com a informação enviada para a estação base.
