Abstract

Se describe una técnica para transmitir o recibir un mensaje de configuración para una señal de referencia de seguimiento de fase, PT-RS, en un canal de radio entre un nodo de acceso de radio y un dispositivo de radio. El canal de radio comprende una pluralidad de subportadores en un bloque de recursos físicos, PRB (602). Un subconjunto de subportadores (608) en el PRB (602) se asigna a una señal de referencia de demodulación, DM-RS. En cuanto a un aspecto del método de la técnica, el mensaje de configuración se transmite al dispositivo de radio. El mensaje de configuración comprende un campo de bits que es indicativo de al menos un subportador asignado a la PT-RS entre el subconjunto de subportadores asignados a la DM-RS. (Figura 8)
