在一些可能的实施方式中，用户设备101可以通过IE MeasAndMobParametersMRDC信令或者IE MeasAndMobParameters信令，向网络设备102发送能力信息。
在一些可能的实施方式中，对于多载波系统中的多载波，例如两个载波、三个载波或者更多载波，PRS与设定下行信号可能分别在不同载波上传输。用户设备101的能力信息用于表征此场景下，用户设备101接收不同载波上信号的能力。

该实施方式中，网络设备102在获得辅助信息，可以确定该能力用户设备101支持在何种载波上测量PRS，以及确定该能力用户设备101何时执行定位测量。从而可以适应性的配置测量间隙的时频资源，例如，配置测量间隙的频域位置(载波)和时域位置(offset和周期等)，即确定测量配置信息。

在一个具体示例中：
LMF103在CC1和CC2上为用户设备101配置了PRS资源。
网络设备102结合第二配置信息在CC1和CC2上分别发送PRS。
在网络设备102和用户设备101支持更多载波时，网络设备102还可以在相同的时域位置在CC3上发送下行参考信号，在CC4上发送PDCCH。其中，PRS、下行参考信号和PDCCH的SCS相同。
