Abstract

La presente invención está diseñada para reducir el impacto de comunicación al usar TTI con diferentes números de símbolos (o diferentes números de RE) sobre el rendimiento de canales de datos. Se proporciona una sección transmisora/receptora que transmite y recibe señales al usar una pluralidad de intervalos de tiempo de transmisión (TTI) con diferentes números de símbolos, y una sección de control. que controla la transmisión y recepción de las señales al aplicar un tamaño de bloque de transporte (TBS) predeterminado en cada TTI, en donde TBS predeterminado en cada TTI se controla de conformidad con el número de símbolos en cada TTI o una tasa de codificación objetivo que se configura por adelantado.
