Patent application numberDescriptionPublished
20100128621COMMUNICATION SYSTEM, BASE STATION, MOBILE STATION, COMMUNICATION METHOD, AND PROGRAM - A base station (05-27-2010
20100188997THROUGHPUT ESTIMATION METHOD AND SYSTEM - In a throughput estimation method for estimating throughput of a first channel in a cellular system in which the first channel and a second channel that are used for an uplink wireless communication service in a cell, noise rise of the second channel is calculated from the traffic volume of the second channel, the noise rise and a target RTWP that is the target total reception power of the base station that is set in the base station are used to calculate a ratio of resources used for the wireless communication service that can be allocated to the first channel, and the resource ratio is then used to calculate the throughput of the first channel.07-29-2010
20100238905WIRELESS COMMUNICATION SYSTEM, BASE STATION, RADIO RESOURCE MANAGEMENT METHOD, AND CONTROL PROGRAM OF BASE STATION - To provide appropriate communication quality inside a building regardless of the building penetration loss of the building in which a femto base station is installed while suppressing the interference caused by radio waves leaked outside the building, a femto base station 09-23-2010
20100240386WIRELESS COMMUNICATION SYSTEM, WIRELESS COMMUNICATION METHOD, BASE STATION, MOBILE STATION, BASE STATION CONTROL METHOD, MOBILE STATION CONTROL METHOD, AND CONTROL PROGRAM - To alleviate interference by a transmission signal on the uplink and downlink of a femto base station to a transmission signal on the uplink and downlink of a macro base station and/or a micro base station. A mobile station 09-23-2010
20100248735WIRELESS COMMUNICATION SYSTEM, WIRELESS COMMUNICATION METHOD, BASE STATION, CONTROL METHOD OF BASE STATION, AND CONTROL PROGRAM OF BASE STATION - To provide appropriate communication quality for a mobile station that is permitted to connect to a femto base station regardless of the place at which the femto base station is installed and the place at which the mobile station is used while reducing the transmission power of the femto base station as much as possible, a femto base station 09-30-2010
20100311415RADIO COMMUNICATION SYSTEM AND METHOD - A mobile station is configured to use, a reception quality of GPS electric wave received by a mobile station, time needed in obtaining GPS location information (or the reception quality of preset television or radio broadcasting) as surrounding environmental information of the mobile station and to control, based on the surrounding environmental information, measurement of a link status (reception quality) and/or reporting of the measurement to a base station. A report from the mobile station is transmitted via the base station and a gateway to a management server which optimizes radio parameter based on the report.12-09-2010
20110207500BASE STATION, RADIO COMMUNICATION SYSTEM, BASE STATION CONTROL METHOD, RADIO COMMUNICATION METHOD, AND CONTROL PROGRAM - [Problems] Because it is not possible to reduce sufficiently the number of base stations that starts uselessly in spite of being in light traffic state, it is not possible to lower interference between adjacent cells and power consumption sufficiently.08-25-2011
