    • The invention relates to a method for supporting cell change between frequency layers. The method is performed in a UE and/or a RN node of a wireless communication network deploying two frequency layers. The RN node serves a UE in a cell of a first of the two frequency layers. The UE is configured to perform measurements on the first frequency layer, and to exclude measurements on a second of the two frequency layers. The method comprises receiving (610) measurement results from the UE, for measurements performed on a cell of the first frequency layer, determining (620) a location of the UE based on the measurement results, assessing (630) a coverage of a target cell of the second frequency layer based on the location and a coverage map for the two frequency layers, and determining (640) whether to change to the target cell based on the assessment.
    • 本发明涉及一种用于支持频率层之间的小区改变的方法。 该方法在部署两个频率层的无线通信网络的UE和/或RN节点中执行。 RN节点服务于两个频率层中的第一个的小区中的UE。 UE被配置为在第一频率层上执行测量,并且排除在两个频率层中的第二频率层上的测量。 该方法包括:接收(610)来自UE的测量结果,对于在第一频率层的小区执行的测量,基于测量结果确定(620)UE的位置,评估(630)目标小区的覆盖范围 基于所述位置和所述两个频率层的覆盖图,并且基于所述评估来确定(640)是否改变到所述目标小区。

    • A technique for cell signature determination in a cellular communication network is provided. A method implementation of this technique comprises the steps of providing a set of hypothesis signals, each hypothesis signal including a signature hypothesis, receiving a composite signal including a first signal portion carrying a first signature from a first cell and a second signal portion carrying a second signature from a second cell, wherein the first signal portion and the second signal portion overlap at least partially in time, and obtaining a correlation result by correlating the composite signal with each hypothesis signal. After the first signature has been determined, a set of phantom signatures associated with the first signature is provided. The phantom signatures represent artifacts from the first signal portion in the correlation result. Finally, the second signature is determined based on the correlation result taking into account the set of phantom signatures associated with the first signature.
    • 提供了一种在蜂窝通信网络中进行小区签名确定的技术。 该技术的方法实现包括以下步骤:提供一组假设信号,每个假设信号包括签名假设,接收包括携带来自第一小区的第一签名的第一信号部分和携带第二信号的第二信号部分的复合信号 签名,其中所述第一信号部分和所述第二信号部分至少部分地在时间上重叠,并且通过将所述复合信号与每个假设信号相关来获得相关结果。 在确定了第一签名之后,提供了与第一签名相关联的一组幻影签名。 幻影签名代表相关结果中来自第一信号部分的伪影。 最后,基于与第一个签名相关联的一组幻影签名的相关结果来确定第二个签名。

    • A method of performing Automatic Gain Control, AGC, in a receiver of a device is provided. The device is served on a serving carrier of a multi-carrier communication network. Measurement gaps are scheduled on the serving carrier for inter-carrier measurements on a non-serving carrier. The method comprises the step of determining a first time interval, in which a predefined signal portion is transmitted on the non-serving carrier; the step of estimating, for the first time interval, received signal power on the non-serving carrier; the step of computing a receiver gain based on the estimate signal power; the step of performing, over a second time interval, an inter-carrier measurement on the non-serving carrier; and the step of applying the receiver gain to the receiver after the second time interval.
