Abstract

Con el fin de transmitir una búsqueda a una terminal de usuario con alta calidad, transmitir una CSI-RS efectivamente y realizar UL HARQ eficientemente en HetNet, la presente invención proporciona un método de comunicación de radio que tiene los pasos de: una micro estación base que está dispuesta en una macro celda y forma una micro celda más pequeña que la macro celda, que transmite, una terminal de usuario, una señal que tiene un subcuadro de CSI-RS que incluye una CSI-RS y un subcuadro de búsqueda que incluye información de notificación que indica modificación e información de sistema y una señal de control que indica no medir una CSI-RS cuando el subcuadro de CSI-RS y el subcuadro de búsqueda chocan entre sí; y la terminal de usuario determina un subcuadro de CSI-RS para medir la CSI-RS con base en la señal de control cuando el subcuadro de CSI-RS y el subcuadro de búsqueda chocan entre sí.
