Abstract
Se presentan modalidades de ejemplo para restricción de subconjuntos de libros de códigos y selección de precodificadores en sistemas de comunicaciones inalámbricas. Por ejemplo, se presenta un ejemplo de método (300) para la restricción de subconjuntos de libros de códigos en un equipo de usuario (UE) (102). En el ejemplo de método, el UE (102) puede recibir, desde un nodo de red (106) tal 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 invención, 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 ejemplo de método incluye restringir los precodificadores seleccionables a partir de un libro de códigos en el segundo grupo de libros de códigos (120) con base en el segundo componente (130). Se presentan métodos del lado de la red, así como ejemplos de UEs (102) y nodos de red (106).
