Abstract

Se describe un método para asignar elementos de recursos en un sistema de multiplexión por división de frecuencia ortogonal (OFDM) para la transmisión de una señal de referencia de información de estado de canal (CSI-RS). El método incluye convertir uno más elementos de recursos en un dominio de frecuencia-tiempo bidimensional; y dividir uno o más elementos de recursos convertidos en unidades de un bloque de recursos físico (PRB). Se diseñan uno o más elementos de recursos sobre por lo menos una porción de PRB para la transmisión de la CSI-RS. De acuerdo con una modalidad, los elementos de recursos de CSI-RS con un mismo índice de subportadoras para una celda común se multiplexan por división de código (CDM), con una dimensión de CDM igual a un número de elementos de recursos de CSI-RS con el mismo índice de subportadoras para la celda común.
