Abstract

Una unidad de repetición (212) realiza una repetición para correlacionar una señal de datos y una señal de referencia de desmodulación (DMRS) repetidamente a un nivel de símbolo a través de una pluralidad de subtramas. Una unidad de asignación de señal (213) correlaciona, en la pluralidad de subtramas, la DMRS repetida con símbolos diferentes de símbolos que corresponden a un candidato de recursos de SRS, el cual es un candidato para un recurso con el cual se debe correlacionar una señal de referencia de sondeo (SRS) que se usa para medir una calidad de señal recibida de enlace ascendente. Una unidad de transmisión (216) transmite una señal de enlace ascendente (PUSCH) que incluye la DMRS y la señal de datos a través de la pluralidad de subtramas.
