| 20080240215 | RESPONSE PROBABILITY CALCULATING DEVICE AND METHOD, AND BASE STATION CONTROL DEVICE AND COMMUNICATION SYSTEM USING THE SAME - There is provided a response probability calculating method for use in a communication system in which a response probability is sent from a communication network to a plurality of terminals, and the terminals report terminal information to the communication network according to the response probability, including a step of selecting a first calculation formula for monotonously increasing the response probability or a second calculation formula for calculating the response probability using the response probability sent at the previous time and the previous number of responses in accordance with the number of responses from the terminals, and a step of calculating the response probability in accordance with the selected calculation formula. | 10-02-2008 |
| 20090154400 | RADIO NETWORK CONTROLLING METHOD, RADIO COMMUNICATION SYSTEM AND RADIO NETWORK CONTROLLER - 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. | 06-18-2009 |
| 20100103828 | CELLULAR SYSTEM, COMMUNICATION PATH QUALITY MEASURING METHOD, BASE STATION, AND MOBILE STATION - A cellular system comprises a mobile station and a base station. The mobile station includes a means for transmitting a pilot signal synchronized with data transmission and a means for transmitting a pilot signal not synchronized with data transmission. The base station includes a means for measuring an interference power based on the received power of the field of the pilot signal synchronized with data transmission, a means for measuring a desired wave power based on the received power of the field of the pilot signal not synchronized with data transmission, and a means for estimating the channel quality of the mobile station based on the interference power and the desired wave power. | 04-29-2010 |
| 20100203886 | TRANSMISSION CONTROL METHOD AND TRANSMISSION CONTROL DEVICE - A transmission control device determines cells, each of which has the number of reception users larger than a predetermined value, as a first group and sends data to the first group cells in the point-to-multipoint transmission mode. The transmission control device also determines cells, each of which has a few MBMS reception users and whose neighboring cell is a first group cell, as a second group and sends data to those cells in the point-to-multipoint transmission mode. The transmission control device sends data to other cells in the point-to-point transmission mode. In this way, the transmission control device selects cells to which data is sent in the point-to-multipoint transmission mode and, at the same time, allows a mobile station near the boundary of those cells to acquire a combining effect. Resource consumption amounts and improve coverage rate can be reduced when same data is sent to multiple mobile stations located in multiple cells. | 08-12-2010 |
| 20100240384 | RESOURCE ALLOCATION METHOD IN COMMUNICATION SYSTEM, RESOURCE ALLOCATION SYSTEM, AND BASE STATION USED FOR THE SAME - The present invention aims to provide a resource allocation method in a communication system that can effectively suppress a transmission delay. Provided is a resource allocation system in a communication system which includes a terminal | 09-23-2010 |
| 20110022714 | CONTROL DEVICE, COMMUNICATION SYSTEM, RESOURCE ALLOCATION METHOD, AND RECORDING MEDIUM CONTAINING PROGRAM - When allocating a resource to a user equipment significantly affected by interference with an adjacent communication area in an uplink, the throughput of the adjacent communication area using the same resource is improved as well as suppressing degradation of the throughput of the user equipment to which the resource is allocated. A control device ( | 01-27-2011 |
