20090117933UPLINK RADIO RESOURCE ALLOCATION METHOD, RADIO BASE STATION, AND RADIO NETWORK CONTROLLER - An uplink radio resource allocation method allocates, at a radio base station, an uplink radio resource used for uplink user data transmission to a mobile station. The method includes: allocating, at the radio base station, the uplink radio resource, so that total received power in an particular cell of the radio base station is equal to a first target value assigned by a radio network controller; and allocating, at the radio station, the uplink radio resource, so that a ratio of first received power from a serving mobile station to second received power from a non-serving mobile station is equal to a second target value assigned by the radio network controller, a serving cell of the serving mobile station being the particular cell, a non-serving cell of the non-serving mobile station being the particular cell.05-07-2009
20090207814RADIO COMMUNICATIONS SYSTEM, RADIO NETWORK CONTROLLER AND BASE STATION - The present invention relates to a radio communications system which transmits same downlink information to a plurality of cells by using downlink common channels. The radio communications system includes a radio network controller and a base station. The radio communications system is configured to measure delays between the time when the radio network controller transmits the downlink information and the time when the base station transmits the downlink information to each of the plurality of cells; and to control timing for transmitting the downlink information to each of the plurality of cells by the base station in accordance with measured delays.08-20-2009
20100093357TRANSMISSION POWER OFFSET ARBITRATION BETWEEN BASE STATIONS DURING SOFT HANDOFF - A transmission power control method for controlling a transmission power of an E-RGCH for uplink user data transmitted from a cell controlled by a radio base station to a mobile station, includes: notifying, from a radio network controller to at least one radio base station controlling a first cell and a second cell, offsets between the transmission power of the E-RGCH and a transmission power of a DPCH, when a mobile station is performing a soft-handover with the first and second cell; determining, at the first cell, a transmission power of a first E-RGCH based on a notified offset, and transmitting the first E-RGCH to the mobile station using the determined transmission power; and determining, at the second cell, transmission power of a second E-RGCH based on a notified offset, and transmitting the second E-RGCH to the mobile station using the determined transmission power.04-15-2010
20100099453TRANSMISSION POWER CONTROL METHOD, AND MOBILE COMMUNICATION SYSTEM - A transmission power control method for controlling a transmission power of an E-HICH for uplink user data transmitted from a cell controlled by a radio base station to a mobile station, includes: notifying, from a radio network controller to at least one radio base station controlling a first cell and a second cell, offsets between the transmission power of the E-HICH and a transmission power of a DPCH, when a mobile station is performing a soft-handover with the first and second cell; determining, at the first cell, a transmission power of a first E-HICH based on a notified offset, and transmitting the first E-HICH to the mobile station using the determined transmission power; and determining, at the second cell, transmission power of a second E-HICH based on a notified offset, and transmitting the second E-HICH to the mobile station using the determined transmission power.04-22-2010
20100110985WINDOW CONTROL AND RETRANSMISSION CONTROL METHOD AND TRANSMITTING-SIDE APPARATUS - In a retransmission control method, a transmitting-side apparatus manages an acknowledgement information reception window; and the transmitting-side apparatus does not perform the window control processing and the retransmission control processing of a packet on the basis of the acknowledgement information for a sequence number of the packet which is included in the acknowledgement information received from the receiving-side apparatus, when the sequence number takes a value outside a range of the acknowledgement information reception window.05-06-2010
20110002318MOBILE STATION, BASE STATION, AND MOBILE COMMUNICATION METHOD - It is an objective of the present invention to efficiently use an uplink radio resource, when transmitting user data based on an uplink high efficient transmission method. A mobile station according to the present invention includes a transmission section configured to transmit high efficient uplink data channel frames for transmitting user data based on the uplink high efficient transmission method, so that transmission timings of the high efficient uplink data channel frames are synchronized among mobile stations located in a single area.01-06-2011
