20090305741 | BASE STATION AND WIRELESS COMMUNICATION SYSTEM - Provided is a wireless base station comprising: a power control unit, a reference information acquisition unit and a reference information storing unit, wherein the wireless base station comprises a first control signal receiving unit for receiving a first uplink control signal used by a mobile station connected to the wireless base station and for requesting the power control unit to control the transmission, and a second control signal receiving unit for receiving a second uplink control signal used by a mobile station connected to the neighbor base station and for requesting the power control unit to control the transmission power, and wherein the power control unit controls the transmission power of the downlink signal based on the request to control the transmission power from the first control signal receiving unit and the request to control the transmission power from the second control signal receiving unit. | 12-10-2009 |
20100157831 | BASE STATION AND ACCESS CONTROL METHOD FOR CELLULAR WIRELESS COMMUNICATION - A base station is connected to wired and wireless networks to send a call that is received from the wired network to the wireless network at a predetermined quality of service (QoS), select one or more combinations of a set of modulation and coding scheme, and a radio resource amount that are associated with a QoS set in a newly incoming call, determine the radio resource amount that is equal to or less than a amount of the unassigned radio resources, assign, to the newly incoming call, the combination that is associated with the determined radio resource amount and the QoS set in the newly incoming call, reduce the radio resources assigned to the ongoing call without changing the QoS, and assign, to the newly incoming call, an amount of radio resources released from the ongoing call and modulation and coding scheme associated with this released radio resource amount. | 06-24-2010 |
20100182972 | WIRELESS COMMUNICATION SYSTEM, MOBILE STATION , AND BASE STATION - In a conventional OFDMA/SCFDMA communication scheme, frequency resource assignment information is exchanged between BSs via a wired interface and used for control of inter-cell interference or the like. When a BS performs assignments of frequency resources, taking the status of a neighbor BS signaled via the wired interface into account, it might be impossible to follow a change in the status of the assignments of frequency resources at the neighbor BS due to a delay occurring in the wired interface. BS selects and assigns distributed frequency resources or continuous frequency resources, depending on the position of an MS in the cell and the transmit power of the BS. | 07-22-2010 |
20100238876 | METHOD FOR RADIO RESOURCE CONTROL AND BASE STATION USING THE SAME - A method for radio resource control is carried out in a radio communications system including multiple base stations. In this method, a radio resource that can be used by the base stations is divided into multiple first radio resources on the frequency axis. Then one or more of the first radio resources are allocated to a second radio resource for initially transmitting a packet and the other first radio resources are allocated to a third radio resource for retransmitting the packet. | 09-23-2010 |
20100309864 | RESOURCE ASSIGNMENT METHOD AND COMMUNICATION APPARATUS FOR WIRELESS COMMUNICATION SYSTEM - Resources are assigned in units of resource blocks each composed of one or more subcarriers, inter-cell interference adjustment control information is notified to each other among base stations, a transmit power limitation on each of the resource blocks in a cell is decided based on the inter-cell interference adjustment control information; and the decision of the transmit power limitation is changed sequentially beginning at a resource block having a transmit power limitation different from the transmit power limitation on an adjacent resource block. | 12-09-2010 |
20100309866 | WIRELESS COMMUNICATION SYSTEM, BASE STATION AND MOBILE STATION - In a system of the present invention, the amount of cell-edge band is limited. In addition, the upper limit of the amount of cell-edge band in each cell is set for limiting the amount of cell-edge band based on the upper limit. The number of cell-edge MSs is also limited. In addition, the upper limit of the number of cell-edge MSs in each cell is set for limiting the number of cell-edge MSs based on the upper limit. | 12-09-2010 |
20100311430 | RADIO COMMUNICATION SYSTEM, BASE STATION AND MOBILE STATION - In a radio-communication system, when wanting to perform high-accuracy scheduling in a base station, a large number of information items, such as channel quality information, desired precoding matrix information and so on, are fed back from a mobile station with a high degree of accuracy. The base station monitors the feedback information and, upon acquisition of it, transmits to the mobile station a certain kind of feedback information which is judged to contribute to scheduling accuracy improvement while preventing the other kinds of feedback information from being sent to the mobile station. | 12-09-2010 |
