Abstract

De acuerdo con un aspecto de esta descripción, la configuración de cuales Recursos de Medición de Interferencias, "IMR", debe medir un equipo de usuario "UE" para el reporte de la información del Estado del Canal, "CSI", se hace más o menos invariante a las variaciones dinámicas del tráfico que afectan el conjunto de puntos de transmisión de Puntos Múltiples Coordinados, "CoMP", usados para dar servicio al UE, o el uso de la supresión dinámica para esos puntos de transmisión. Estos objetivos se logran al menos en parte al configurar uno o más de los puntos de transmisión para seguir una primera regla que implementa una lógica negativa. De acuerdo con la primera regla, los puntos de transmisión transmiten en un IMR dado si se ha considerado que no es probable que transmita datos en el tiempo relevante para el IMR, y por el contrario, no transmite el IMR si se ha considerado que es probable que transmita datos en el tiempo relevante para el IMR.
