Abstract

Un nodo de red de radio (RNN) 210 y un método para configurar las señales de referencia de Demodulación (DMRS) de un dispositivo inalámbrico 208. El RNN 210 y el dispositivo 208 funcionan en una red de comunicaciones inalámbricas 200. El RNN indica una configuración de DMRS para el dispositivo inalámbrico, cuya configuración de DMRS se puede configurar dinámicamente para relacionarse con uno o más de un primer símbolo de multiplexación por división de frecuencia ortogonal (OFDM) que comprende las DMRS para una primera transmisión; y un segundo símbolo OFDM que comprende las DMRS para la primera transmisión.
