摘要： When handover control is performed in a wireless communication system in which a plurality of base stations and a plurality of mobile stations communicate wirelessly, the necessary radio resources are secured beforehand in a handover-destination radio base station before handover is performed, and handover is executed thereafter. In order to secure the radio resources, one or more mobile stations that are already communicating via the handover-destination base station are forcibly handed over to another radio base station, whereby the radio resources of the handover-destination radio base station are secured. This is followed by executing handover.

摘要： A transmitting device for transmitting data by means of wireless signals to at least one of a plurality of receiving devices via a channel shared by the plurality of receiving devices is provided. The transmitting device receives reception quality data from each of the plurality of receiving devices; determines future predicted values relating to the reception quality of the respective receiving devices on the basis of the one or plurality of sets of past reception quality data; and selects receiving devices and assigns transmission data to be transmitted to the selected receiving devices to the channel on the basis of the future predicted values. The rate of generation of reception data errors on the side of the receiving devices and data re-transmission rate due to data errors can be reduced, and the throughput can be improved.

摘要： The present invention relates to a transmission band allocating device which effectively and freely allocates a band used for each packet transmission in a packet wireless transmission system. It is an object of the present invention to fairly provide a service to terminals and to enhance the throughput at the same time. To this end, the transmission band allocating device according to the present invention is configured by modifying a maximum CIR method such that a band is preferentially allocated to a terminal having precedently allocated a band whose integrated value is small.

摘要： A plurality of sub word lines each have a length equivalent to the division of a main word line along the extension direction thereof, arranged along a bit line crossing said main word line, and are connected with a plurality of memory cells. A first sub word select line arranged in parallel to the main word line is extended to a plurality of sub arrays arranged in the extension direction of the word line. A second sub word select line is connected to the corresponding one of said first sub word select line to be extended orthogonally to a word line driving circuit area of an adjacent sub array. In the sub word line driving circuit provided for each sub array, a sub word line is selected and deselected by signals supplied from said main word line and said second sub word select line.
