摘要： To provide good communication quality inside a building while suppressing interference exerted on communication of other radio stations by radio waves leaked outside the building. A femto base station 1 performs radio communication with mobile stations 6-1 and 6-2. The femto base station 1 includes a radio resource control unit 15. The radio resource control unit 15 obtains a measured value of a reception quality level that is obtained by the femto base station 1 and the mobile stations 6-1 and 6-2 by measuring the reception quality level of an external radio signal S1. Further, the radio resource control unit 15 determines a radio parameter relating to radio communication between the femto base station 1 and the mobile stations 6-1 and 6-2 based on a relative comparison between a plurality of reception quality levels. The external radio signal S1 is a radio signal transmitted from an external radio station 9 that is different from any of the femto base station 1 and the mobile stations 6-1 and 6-2.

摘要： A transmission power control method that reduces the possibility of going out of synchronization is presented. In a reduced power mode, a target SIR is set equal to or higher than SIR_reduced where deemed appropriate, whereby frequent issues of Out-of-sync and the probability of generation of RL_Failure are suppressed. To raise a reception SIR to a value equal to or higher than SIR_reduced, the target SIR may be periodically set at SIR_temp that is a value equal to or higher than SIR_reduced. Alternatively, when brought in the reduced power mode, a mobile station itself may periodically set its transmission power such that a value equal to or higher than SIR_reduced can be achieved.

摘要： A transmission power control system can establish synchronization by matching adjustment start timings while repeating adjustment periods even when start timings of transmission power balance adjustment are different due to fluctuation of transmission delay of control message from the control station to base station, and can increase circuit capacity by establishing balance of transmission powers between the base stations. In the transmission power control system the base station comprises control means for controlling initiation of a balance adjustment period for performing the balance adjustment from a frame number determined on the basis of frame number of the balance adjustment period.

摘要： In a pilot signal transmission method for raising the SIR measurement accuracy for transmission power control during high-speed transmission and thus reducing the block error rate and improving the throughput, a first SIR value measured by first pilot signals and second SIR value measured by second pilot signals are first compared, and the presence or absence of second pilot signals then determined in slot units based on the comparison results. When the second pilot signals exist, the second pilot signals are used in addition to the first pilot signals in the SIR measurement for high-speed closed-loop transmission power control. When the second pilot signals do not exist, only the first pilot signals are used in the SIR measurement for high-speed closed-loop transmission power control.

摘要： Base stations control the transmission rate that is used by UE (user equipment) to forward them information. A UE periodically forwards a rate request to a base station if the UE needs to have its data transmission rate to the base station increased or decreased, and the base station responds with a rate command. An error can occur in the transmission of the rate command, such that a rate Rnb transmitted by the base station and detected by the UE as Rue may not match. Various schemes are proposed for reducing and correcting such transmission errors. A first scheme involves periodically resetting the transmission rate of the base station and UE with a reference rate. Second to fourth schemes involve periodically comparing the transmission rates of the base station and UE, and replacing the rate of the UE if they differ. A fifth scheme involves a filtering of the feedback command in order to reduce the impact of error propagation. A sixth scheme, which may be used separately or in conjunction with any of the foregoing schemes, involves adjusting a power offset with a repetition factor. All of the schemes are modified during a soft handover of the UE from the base station to a new base station.
摘要翻译：基站控制UE（用户设备）使用的传输速率来转发它们的信息。如果UE需要使其基站的数据传输速率增加或减小，则UE周期性地将速率请求转发到基站，并且基站以速率命令进行响应。在速率命令的传输中可能发生错误，使得由基站发送并由UE检测到的速率Rnb可能不匹配。提出了用于减少和校正这种传输错误的各种方案。第一方案涉及以参考速率周期性地重置基站和UE的传输速率。第二到第四方案包括周期性地比较基站和UE的传输速率，并且如果它们不同，则替换UE的速率。第五个方案涉及反馈命令的过滤，以减少误差传播的影响。可以单独使用或与任何前述方案结合使用的第六方案涉及用重复因素调整功率偏移。所有方案在UE从基站到新基站的软切换期间被修改。

摘要： A base station 1 includes a radio communication unit 11 and a frequency channel control unit 15. The radio communication unit 11 is capable of forming a primary cell and a secondary cell, and transmitting a physical channel for data transmission (HS-PDSCH) in each of these two cells. Further, the frequency channel control unit 15 determines a frequency channel available to the secondary cell based on the load status of a nearby cell formed by a nearby base station 7. In this way, the interference to the nearby cell caused by the base station 1 is suppressed.
