摘要： A method and device for controlling a mobile user equipment being in radio communication with base stations of a wireless communication system. The transmit power of the user equipment is controlled by the communication system. Immediately before sending an event message by the user equipment, the transmit power is increased by the user equipment, in order to increase the likelihood that the message is properly received by the base station. The message may be a soft handover event message. The transmit power is increased by opening a closed loop power control circuit, which normally controls the transmit power of the user equipment. By opening the closed loop circuit, the user equipment takes over the control of its transmitted power for increase thereof. Following the sending of the message, the user equipment may control the base station to send with increased power by increasing a target signal-to-interference ratio value (SIR ref ) by means of which the base station power level is controlled. In this way, the likelihood of receiving any acknowledgement messages and event messages from the base station is increased.

摘要： Link quality control information is generated by receiving a received signal from a front end receiver. Time dispersion information is then estimated during a synchronization of the received signal. Then, link quality control information is generated using the time dispersion information. The link quality control information includes information pertaining to an optimal tansmission parameter. The link quality control information can be transmitted back to a unit that transmitted the received signal so that the appropriate transmission parameters may be adjusted.

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，对于这种测量的常规方法易受不准确性的影响。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，对于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。
