摘要： A user equipment is operated in a mobile communications system, wherein a network part of the mobile communications system is capable of operating in a synchronized mode or in an asynchronous mode. Operation includes recording timing information about a periodically occurring signal received from a neighboring cell. The recorded timing information is used in a blind detection proc\ ess that ascertains whether the network part of the mobile communications system is operating in the synchronized mode or in the asynchronous mode by detecting at least whether the periodically occurring signal received from the neighboring cell occurred within a predetermined window of time of a corresponding periodically occurring signal received from a serving cell. The detected operating mode of the network part of the mobile communications system is used for controlling subsequent operation of the user equipment.

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。

摘要： A user equipment (UE) in a cellular telecommunications system is able to detect the uplink/downlink configuration of a detected neighboring cell by receiving a signal from the neighboring cell. A characteristic of the received signal is detected and used as an indicator in a blind detection process to identify one or more downlink slots in the received signal. Known pilot signals in the identified one or more downlink slots can then be used to obtain a signal power measurement of the received signal. The blind detection process is also capable of detecting whether a slot of a neighboring cell's signal is a downlink unicast slot or a Multicast-Broadcast Single Frequency Network slot.
