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于不准确。非限制性示例场景包括其中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/或不同带宽下工作的相邻载波产生。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) cell search involves tuning a demodulation frequency of the UE based on signals received from a first encountered cell and using a non-initial cell search procedure to continue searching for a cell that is qualified for camping on, wherein the non-initial cell search procedure relies on the demodulation frequency being within limits of accuracy that enable successful reception and decoding of received information. Prior to finding a qualified cell, information enabling a first discovered unqualified cell to again be found is saved. After a period of time during which the non-initial cell search procedure has been performed and before the UE's demodulation frequency is beyond acceptable limits of accuracy, the saved information is used to again tune the demodulation frequency based on reading signals from the first discovered unqualified cell. The UE then continues to perform the non-initial cell search procedure.

摘要： A method of a wireless communication device for a cellular communication system is disclosed. According to the method, a signal comprising a first known signal sequence and a second known signal sequence for each of one or more first cells of the cellular communication system is received, and the first and second known signal sequences of each of the one or more first cells are detected based on the received signal. For at least one of the one or more first cells, one of the first known signal sequence, the second known signal sequence, and a combination of the first and second known signal sequences is selected for channel estimation. The selection is based on the detected first and second known signal sequences of the one or more cells. Channel estimation of the at least one of the one or more first cells is performed based on the signal sequence selection. In some examples, the method may further comprise performing interference cancellation of at least one of the first and second known signal sequences of the at least one of the one or more first cells based on the channel estimation and detecting one or more second cells of the cellular communication system after the interference cancellation. Corresponding computer program product, arrangement and wireless communication device are also disclosed.

摘要： A communication system node transmits first control channel information on a control channel that extends over a first bandwidth of a radiofrequency resource. The first control channel information is necessary to enable a first type of communication device, capable of receiving a signal having the first bandwidth, to establish a connection with a host cell. A MIB, occupying a second bandwidth-size part of the first bandwidth, is transmitted. The second bandwidth is smaller than the first bandwidth and is receivable by a second type of communication device having reduced receive bandwidth capabilities. The MIB has a first part comprising first part information necessary to enable the first type of communication device to establish the connection with the host cell, and a second part comprising second part information directly or indirectly enabling the second type of communication device to obtain parameters that enable connection establishment with the host cell.
