Abstract: When determination is made that a channel for high-speed downlink packet transmission is short in power by the calculation of power assigned to a downlink shared channel and an activity ratio of the power assigned to the downlink shared channel from transmission power of all the channels and transmission power of other channel than a downlink shared channel for high-speed downlink packet transmission, a total sum of transmission power of dedicated channels is reduced by lowering a rate of a connected dedicated channel for data reception, thereby increasing power assigned to the channel for high-speed downlink packet transmission.

Abstract: 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.

A base station operating section of a base station is provided with respective functions for: measuring an RTWP which is a total receiving power; reading a format of a transport block transmitted by E-DPDCH; and measuring a transfer rate of each mobile station. In addition, a buffer size calculation section of the base station calculates an estimated buffer size at the time of transmission by a mobile station using an allocated power resource. An allocated power resource section calculates a power resource to be allocated to each mobile station, and notifies a power resource to be allocated to a mobile station via the base station operating section.

Abstract: A best-cell amendment method is disclosed for amending hysteresis margins according to the degree of congestion. A radio network controller (RNC) compares the average value P(k) of transmission power of a downlink shared channel PDSCH of cell k and a first threshold value P_threshold1 to measure the degree of congestion. If the RNC determines that the degree of congestion in cell k is high, it sets a small hysteresis margin hm_a, and if RNC determines that the degree of congestion in cell k is low, it sets a large hysteresis margin hm_b.

Abstract: 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.
