Abstract

Se describe un método para asignar elementos de recurso 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) sin solapamiento con elementos de recursos asignados en una señal de señal de referencia de equipo específico de usuario (URS) de cinco puertos. El método puede incluir cambiar en un dominio de frecuencia por lo menos una porción de los elementos de recursos asignados a la CSI-RS en una subtrama de OP normal. De acuerdo a ciertas modalidades, la asignación de elementos de recursos puede definirse por una CSI-RS de ocho puertos, o por un grupo de ocho elementos de recursos CSI-RS, dentro de un bloque de recursos físicos (PRB) sencillo cuya dimensión de dominio de tiempo es una subtrama y cuya dimensión de dominio de frecuencia es doce subportadoras.
