Abstract: 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.

Abstract: 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.

Abstract translation: 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。
