Abstract

Se presentan en las realizaciones para restricción de subconjunto de libro de códigos y selección de precodificador en sistemas de comunicaciones inalámbricas. Por ejemplo, se presenta un método de ejemplo (300) para la restricción de subconjuntos de libro de códigos en un equipo de usuario (UE) (102). En el método de ejemplo, el UE (102) puede recibir, desde un nodo de red (106) como un gNB, señalización de restricción de subconjunto de códigos (CBSR) para un primer componente (128) común a precodificadores en un primer grupo de libros de códigos (118). En un aspecto de la presente divulgación, una restricción del primer componente (128) se correlaciona con una restricción de un segundo componente y el segundo componente (130) es común a los precodificadores en un segundo grupo de libros de códigos (120). Además, el método de ejemplo incluye restringir precodificadores seleccionables de un libro de códigos en el segundo grupo de libros de códigos (120) en base al segundo componente (130). Se presentan métodos del lado de la red, así como ejemplos de UE (102) y nodos de red (106).
