摘要： The present invention provides a radio base station which can equally assign a transmission opportunity based on the radio channel quality. A mobile station selection unit issues a request for a metric notification to a metric notification unit corresponding to a mobile station notified by a data flow control unit, and receives metrics. The metric notification unit periodically receives radio channel quality information from a channel quality notification unit of an uplink signal analysis unit, obtains through a rank calculation unit the rank at the time when the channel quality is preferably arranged in a channel quality buffer according to the radio channel quality information, and notifies the mobile station selection unit of the result as metrics. The mobile station selection unit selects a mobile station having the smallest metrics notified by the metric notification unit, assigns radio resources to the mobile station, and notifies the data flow control unit of the assignment.

摘要： The invention provides a radio base station which can achieve high throughput while attaining the target quality for each mobile station and fairly assigning a transmission opportunity. In the radio base station, when a mobile station selection unit is notified at a fixed period of time by a data flow control unit with respect to a mobile station which has data to be transmitted, the unit selects a plurality of mobile stations which don't achieve the service quality. The plurality of mobile stations selected by the mobile station selection unit are input into a PF scheduler. From these mobile stations, a mobile station to which a transmission opportunity is assigned, is determined. A mobile station notification unit assigns a transmission opportunity to the mobile station determined by the PF scheduler. Upon completion of the transmission opportunity assignment, the mobile station notification unit notifies the data flow control unit of the mobile stations to which a transmission opportunity has been assigned.

摘要： A mobile communication system capable of improving the system throughput. A base station (1) divides one cell into three sectors. A common pilot channel is transmitted to a plurality of mobile stations in the sectors by beams (101-103) whose directivity is controlled by an adaptive antenna for each of the sectors. On the other hand, when a mobile station (2) communicates data with the base station (1), the base station transmits a data channel and an individual control channel to the mobile station (2) by using a beam (201) whose directivity is controlled individually. The mobile station (2) switches between the common pilot channel and the individual control channel from the base station (1) for estimating the communication path quality.

摘要： When a downlink communication channel quality is informed of in the downlink packet communication using a shared channel, the communication channel quality for each RB that is obtained by dividing a downlink into a plurality of small bands (RBs) is informed of via the uplink. As the downlink band is getting wider, the number of RBs increases and the bands required to inform via the uplink also increases. Then, in the mobile station, RBs whose the communication channel quality is at a predetermined threshold or more are selected as a selected group, with the others considered as in the non-selected group, the information indicating which groups do they belong to is generated as a bitmap, and then the average value, the minimum value and the maximum value of the communication channel quality of the RBs are also obtained. Then the minimum or the maximum value is transmitted as a represented value of the selected group, the average value is transmitted as a representative value of the non-selected group, and also the bitmap is transmitted to the base station. At the base station, the communication channel quality for each RB is restored by replacing the communication channel quality belonging to the selected group by the minimum or the maximum value, and the communication channel quality belonging to the non-selected group by the average value.
