Abstract

Un procedimiento para la comunicación inalámbrica, que comprende: identificar (612) una primer estación que observa una interferencia alta de una segunda estación en una red heterogénea que comprende estaciones base (110, 112, 114, 116, 118) de al menos dos niveles diferentes de potencia de transmisión; y mitigar (614) la interferencia a una primer señal de referencia mediante la selección de diferentes recursos para el envío de una segunda señal de referencia por la segunda estación para evitar la colisión con la primera señal de referencia, en el que el mitigar la interferencia se caracteriza por comprender adicionalmente determinar primeros recursos usados para el envío de la primera señal de referencia por la primera estación, seleccionar una identidad de celda asociada con segundos recursos para el envío de la segunda señal de referencia, siendo los segundos recursos diferentes a los primeros recursos, y enviar la segunda señal de referencia sobre los segundos recursos por parte de la segunda estación.
