Abstract

De conformidad con un aspecto, un nodo inalámbrico selecciona un conjunto de puertos de antena de señal de referencia para usarse en la transmisión de datos a otros nodos inalámbricos en un intervalo de tiempo de transmisión dado, de una pluralidad de conjuntos de puertos de antena de señal de referencia que están disponibles para usarse y que incluyen puertos de antena de señal de referencia que tienen diferentes densidades de señal de referencia en la dimensión de frecuencia y/o tiempo. El nodo inalámbrico envía un mensaje a un segundo nodo inalámbrico que indica una asignación de señal de referencia e incluye una indicación del conjunto seleccionado de puertos de antena de señal de referencia.
