Abstract: Embodiments herein relate to a method performed by a receiving device (10, 12) for handling signalling in a wireless communication network. The receiving device measures a strength, or a complex amplitude, of one or more signals over a signal path to a transmitting device (12, 10), which measured strength or complex amplitude forms a signal pattern over a time. Furthermore, the receiving device (10, 12) matches the signal pattern with a stored signal pattern; and in case the signal pattern matches the stored signal pattern; the receiving device (10, 12) determines that an object will block the signal path between the receiving device and the transmitting device.
