    • A telecommunications system for improving quality of service (QoS) to users via the implementation of an extended outer loop power control algorithm. A radio resource manager (RRM) operates to determine the number of chapels allotted to users within a network at a certain time. The RRM implements the extended outer loop power control algorithm for each allotted channel, thus determining SIR reference values for each allotted channel. The RRM ensures that the SIR reference value for any channel does not fall below a predetermined minimum value. The SIR reference value to be used for all channels in use is determined as the highest of all the calculated SIR reference values. The extended outerloop power control algorithm can be implemented at a mobile station level, base station level or radio network controller level.
    • 一种用于通过实施扩展外环功率控制算法来改善用户服务质量(QoS)的电信系统。 无线电资源管理器(RRM)用于确定在特定时间内分配给网络中的用户的教堂的数量。 RRM为每个分配的信道实现扩展的外环功率控制算法,从而确定每个分配的信道的SIR参考值。 RRM确保任何通道的SIR参考值不会低于预定的最小值。 要用于所有使用的通道的SIR参考值被确定为所有计算的SIR参考值中的最高值。 扩展外环功率控制算法可以在移动台级,基站级或无线网络控制器级实现。

    • A method for generating a power control command in a transceiver in a wireless communication system, where the method comprises the steps of calculating, at the beginning of a predefined time period, a quality measure reference value, generating, repeatedly during the predefined time period, an estimated quality measure value of a signal received at the transceiver; generating a power control command in dependence of the estimated quality measure value and the quality measure reference value; and generating, a number of times during the predefined time period, a modified quality measure reference value from the quality measure reference value. The step of generating the power control command comprises comparing the estimated quality measure value with the modified quality measure reference value. A power control unit, comprising a quality measure estimator, a calculator, a first controller, a second controller and an inner loop element, is configured to implement the method.

    • The automatic frequency correction value applied by a receiver is altered to minimize long-term drift of a path delay profile. In one embodiment, the phase or timing error resulting from constant frequency corrections is accumulated, and an estimated frequency correction value is selectively quantized into an actual frequency correction value in response to the accumulated phase/timing error. The quantized value above or below the estimate is selected to minimize the accumulated phase/timing error that gives rise to path delay profile drift. In another embodiment, a timing circuit measures the instantaneous path delay profile drift incurred with each frequency correction, and integrates the instantaneous drift measurements over time to yield a path delay profile drift. The drift (or its rate of change) is then used to adjust a frequency correction value so as to minimize the drift.
    • 由接收机施加的自动频率校正值被改变以最小化路径延迟分布的长期漂移。 在一个实施例中,累积了由恒定频率校正引起的相位或定时误差,并且响应于累积的相位/定时误差,将估计频率校正值选择性地量化为实际频率校正值。 选择高于或低于估计的量化值以最小化引起路径延迟分布漂移的累积相位/定时误差。 在另一个实施例中,定时电路测量每个频率校正引起的瞬时路径延迟分布漂移,并且随着时间的推移积分瞬时漂移测量值,以产生路径延迟分布漂移。 然后使用漂移(或其变化率)来调整频率校正值,以便使漂移最小化。
