Abstract

Se efectúa la divulgación para la transmisión y recepción de enlace ascendente en un sistema de comunicación inalámbrica y un aparato para las mismas. Específicamente, un método para efectuar la transmisión de enlace ascendente mediante un equipo usuario (EU) en un sistema de comunicación inalámbrica puede comprender los pasos de: recepción de información de control de recepción de enlace descendente (DCI) que incluye indicación de recursos (SRI) de la señal de referencia de resonancia (SRS) e indicación de precodificación proveniente de una estación base; y la transmisión de un enlace ascendente a la estación base aplicando la precodificación indicada mediante la indicación de precodificación en un puerto de antena de una SRS transmitida en un recurso de SRS seleccionado por la SRI.
