Abstract

Se suministran mecanismos para monitorear espacios de búsqueda. Un primer método realizado por un dispositivo inalámbrico comprende recibir un símbolo OFDM en una ranura de enlace descendente. Por lo menos parte del símbolo OFDM está incluido en un espacio de búsqueda específico de dispositivo y en un espacio de búsqueda común. El primer método comprende monitorear el espacio de búsqueda específico de dispositivo por al menos una señal de referencia (RS) específica de dispositivo y monitorear el espacio de búsqueda común por al menos una RS no específica de dispositivo. En un segundo método, un nodo de red de acceso de radio transmite un símbolo OFDM incluido en un espacio de búsqueda específico de dispositivo y en un espacio de búsqueda común. El espacio de búsqueda específico de dispositivo contiene una RS específica de dispositivo, o el espacio de búsqueda no específico de dispositivo contiene una RS no específica de dispositivo, o se aplica ambos de estos.
