Abstract

Métodos y aparatos para configurar, en un nodo de red (110) de una red de comunicaciones inalámbricas, un recurso de señal de referencia empleado para efectuar las mediciones de información de estado de canal, CSI, con uno o más dispositivos inalámbricos. En un método ejemplificativo, se agrega un recurso de señal de referencia en uno o más de un dominio de frecuencia y un dominio de tiempo, y se ajusta una característica de densidad del recurso agregado de señal de referencia que debe transmitirse al uno o más dispositivos inalámbricos (105).
