Abstract

Un nodo de red de radio (RNN) 210 y un método de la misma para la configuración de señales de referencia de demodulación (DMRS) de un dispositivo inalámbrico 208. El RNN 210 y el dispositivo inalámbrico 208 están operando en una red de comunicaciones inalámbricas 200. El RNN indica una configuración de DMRS al dispositivo inalámbrico, tal 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 de OFDM que comprende las DMRS para la primera transmisión.
