Abstract

Las modalidades de la presente descripción se refieren a métodos, dispositivos, aparatos y medios de almacenamiento legibles por computadora para el diseño de información de control de enlace ascendente (UCI). El método comprende determinar, en un dispositivo terminal, una matriz que comprende un conjunto de coeficientes de combinación lineal distintos de cero para cuantificar un canal entre el dispositivo terminal y un dispositivo de red, donde la matriz tiene componentes espaciales y componentes de frecuencia; desplazar los componentes de frecuencia de la matriz de forma circular, de modo que un coeficiente objetivo del conjunto de coeficientes de combinación lineal distintos de cero se ubique en un componente de frecuencia con un índice predeterminado de los componentes de frecuencia en una matriz desplazada; generar una primera indicación que indique el componente espacial asociado con el coeficiente objetivo en la matriz; y transmitir, al dispositivo de red, información de control de enlace ascendente que comprende la primera indicación. De esta manera, una nueva solución para el diseño de la UCI puede reducir los gastos generales para reportar los parámetros en la “UCI parte 1” y la “UCI parte 2”.
