Abstract

a presente invenção refere-se a uma unidade de repetição (212) que realiza a repetição para mapear um sinal de dados e um sinal de referência de desmodulação (dmrs) repetidamente a um nível do símbolo sobre a pluralidade de subquadros. uma unidade de alocação de sinal (213) mapeia, na pluralidade de subquadros, o dmrs repetido para os símbolos diferente de símbolos que correspondem a um candidato de recurso de srs, que é um candidato para um recurso ao qual um sinal de referência sonoro (srs) a ser usado para medir a qualidade de sinal recebido de enlace ascendente tem que ser mapeado. a unidade de transmissão (216) transmite um sinal de enlace ascendente (pusch) que inclui o dmrs e os sinais de dados sobre a pluralidade de subquadros.
