  • RECEIVING DEVICE AND METHOD PERFORMED THEREIN FOR HANDLING SIGNALING IN A WIRELESS COMMUNICATION NETWORK
    Publication number: 20190260406
    Abstract: Embodiments herein relate to a method performed by a receiving device 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, which measured strength or complex amplitude forms a signal pattern over a time. Furthermore, the receiving device matches the signal pattern with a stored signal pattern and, if the signal pattern matches the stored signal pattern, the receiving device determines whether an object will block the signal path between the receiving device and the transmitting device.
