GENERATION UNIT OF INTERFERENCE OVERLOAD INDICATOR, GENERATION METHOD OF INTERFERENCE OVERLOAD INDICATOR, GENERATION CONTROLLER OF INTERFERENCE OVERLOAD INDICATOR, GENERATION CONTROL METHOD OF INTERFERENCE OVERLOAD INDICATOR, INDICATION METHOD OF INTERFERENCE OVERLOAD, AND BASE STATION
pThe present invention provides an interference-overload-indicator generating device, a method of generating an interference overload indicator, an interference-overload-indicator generation controller, a method of controlling interference-overload-indicator generation, and a method of indicating interference overload, and a base station utilizing these methods, each of which is used in an uplink FDMA cellular communication system. The base station includes an interference-overload-indicator generation control sub-system (1000), an interference-overload-indicator generation sub-system (2000), and a transmitting/receiving sub-system (3000). The interference-overload-indicator generation control sub-system (1000) judges whether or not a condition to initiate interference indicator generation is satisfied, and activates the interference-overload-indicator generation sub-system (2000) only when the condition is satisfied. This makes it possible to reduce a signaling size of the interference indicator. For further reducing the signaling size, an interference indicator signaling is generated by a method such as differential coding, state coding, or a bitmap, and transmitted. According to the present invention, an interference overload indicator generation control mechanism is relatively simple and the signaling size of the interference indicator is small./p [EP2262330A1]
