Abstract:
A base station for a mobile communication system includes a speed detecting unit configured to detect the moving speed of a user device based on a signal received from the user device and indicating the moving speed; and a determining unit configured to select, based on the moving speed detected by the speed detecting unit, a wideband channel quality indicator indicating reception quality of an entire system frequency band allocated to the mobile communication system, or a combination of the wideband channel quality indicator and one or more channel quality indicators of subbands in the system frequency band as channel quality information that needs to be reported from the user device to the base station.
