摘要： In a cellular radio system Transmission Power Control (TPC) power offset is set so that it is adjusted for each transmitting radio base station based on available relevant measurements that reflect the quality of the downlink channel carrying the uplink TPC command whereby an improved performance is obtained. The TPC power offset can for example be based on an estimated uplink Dedicated Physical Control CHannel (DPCCH) SINR, the number of TPC “up” and the number of TPC “down” sent by a radio base station and aggregated UE receiver power or UE transmit power over a number N slots. Also a mobile station used in a cellular radio system supporting soft handover may be adapted to apply TPC discarding thresholds based on the number and the quality of simultaneously received TPC commands. The discarding procedure in the mobile station may also be carried out selectively such that TPC commands that are determined to be unreliable are not discarded but selectively discarded based on how reliable they are determined to be.
摘要翻译：在蜂窝无线电系统中，传输功率控制（TPC）功率偏移被设置为使得根据反映进行上行链路TPC命令的下行链路信道的质量的可用的相关测量来调整每个发射无线电基站，由此获得改进的性能。 TPC功率偏移可以例如基于估计的上行链路专用物理控制信道（DPCCH）SINR，由无线电基站发送的TPC向上的数量和TPC的次数以及聚合的UE接收机功率或者UE上的发射功率 N号插槽此外，支持软切换的蜂窝无线电系统中使用的移动站也可以适用于基于同时接收的TPC命令的数量和质量来应用TPC丢弃阈值。也可以选择性地执行移动台中的丢弃过程，使得被确定为不可靠的TPC命令不被丢弃，而是基于它们被确定的可靠性而被选择性地丢弃。

摘要： One aspect of the present invention is method for signal quality measurement that provides significant improvements in accuracy, at least in certain scenarios where conventional approaches to such measurements are vulnerable to inaccuracies. Non-limiting example scenarios include instances where a communication network uses downlink carriers in neighboring cells with overlapping frequencies but with different bandwidths and/or center frequencies. In such cases, there may be uneven interference across the carrier bandwidth, e.g., arising from neighboring carriers operating at different center frequencies and/or at different bandwidths. Thus, making the signal quality measurement for a given carrier depend on a combination of measurements taken at different frequency regions of the carrier provides a clearer, more accurate picture of the interference or loading conditions bearing on that carrier.
摘要翻译：本发明的一个方面是用于信号质量测量的方法，其提供了精确性的显着改进，至少在某些情况下，对这种测量的常规方法易于不准确。非限制性示例场景包括通信网络使用具有重叠频率但具有不同带宽和/或中心频率的相邻小区中的下行链路载波的情况。在这种情况下，跨载波带宽可能存在不均匀的干扰，例如由在不同中心频率和/或不同带宽下运行的相邻载波产生。因此，对给定载波进行信号质量测量取决于在载波的不同频率区域进行的测量的组合，提供对该载波的干扰或负载条件的更清楚，更准确的图像。

摘要： The present invention relates to methods and devices for mobility management UE in a cellular communications system. A user equipment maintains (21) at least two sets of mobility trigger parameters. Each set of mobility trigger parameters corresponds to a predetermined user equipment speed range. The user equipment determines (22) a speed range that the speed of the user equipment falls into and selects (23), based on the determined speed range, at least one set of mobility trigger parameters to be used for performing mobility-based decisions. If the user equipment is in connected mode a network base station may select a set of mobility trigger parameters to be used for performing handover decisions based on a determined speed range of the user equipment. Advantages are that ping-pong mobility decisions may be avoided and it is sufficient to determine a range for the UE speed, which is less complicated than determining an accurate speed of the UE particularly in idle mode.

摘要： A user equipment performs downlink measurement on neighbour cells, but the measurement performance on a target cell (in terms of measurement period/sampling/accuracy etc) is dependent on the relative performance difference between the target cell and a reference cell. The reference cell may be the serving cell, or may be the strongest cell. The network is thus able to keep track of the required number of target cells without degrading the measurement performance of important cells. The UE on the other hand is still able to save its battery as much as possible while making full use of DRX.
摘要翻译：用户设备对相邻小区进行下行链路测量，但是目标小区（在测量周期/采样/精度等方面）的测量性能取决于目标小区与参考小区之间的相对性能差异。参考单元可以是服务小区，或者可以是最强小区。因此，网络能够跟踪所需数量的目标小区而不降低重要小区的测量性能。另一方面，UE在充分利用DRX的同时仍能够尽可能地节省电池。
