Abstract

Un equipo de usuario (UE) (200, 500, 1530) transmite datos a una estación base (100, 500, 1520) en una red de comunicación inalámbrica. El UE (200, 500, 1530) comprende varios puertos de antena y selecciona una matriz de precodificación de un primero, segundo, tercero y cuarto conjuntos de matrices de precodificación respectivos de acuerdo con un número de capas espaciales. El primero, segundo, tercero o cuarto conjuntos de matrices de precodificación están disponibles para todas las capacidades de coherencia y están comprendidos dentro de un conjunto más grande de matrices de precodificación. El conjunto más grande comprende matrices de precodificación que no están disponibles para todas las capacidades de coherencia. El primero, segundo, tercero y cuarto conjuntos de matrices de precodificación corresponden a una, dos, tres o cuatro capas espaciales, respectivamente. El número de columnas en la matriz de precodificación seleccionada es igual al número de capas espaciales y cada columna comprende un solo elemento distinto de cero y uno o más elementos cero. El UE (200, 500, 1530) transmite datos sobre el número de capas espaciales de acuerdo con la matriz de precodificación seleccionada.
