  • Patent number: 10243683
    Abstract: A technique for cancelling interference in a cellular network (100) is provided. The cellular network (100) comprises intra-frequency cells (102, 104, 106) sending a first identifying signal indicative of a first identifier (ID1) and a second identifying signal indicative of a second identifier (ID2). Each of the cells is identified by a combination of the first identifier and the second identifier. As to a method aspect of the technique, first samples of the first identifying signal are extracted from a signal received by a User Equipment (120). The first samples include contributions from different cells (104, 106) of the cellular network (100). A first set of sample points is selected based on the first samples and a first candidate (104-1) for the first identifier (ID1). Second samples of the second identifying signal are extracted from the received signal. The second sample includes contributions from the different cells (104, 106).

  • Publication number: 20180310274
    Abstract: Systems and methods of the present disclosure provide a way to pinpoint where a target device associated with an IP address is physically located within a geographical region. Network-communication delays between landmark devices and the target device are determined and used to generate sequences capturing relative delay relationships between the landmark devices and the target device. The sequences are used to determine a ranking via a sequence-matching approach. For each pair of landmark devices, a geographical boundary that divides the geographical region into a target partition and a second partition is determined. The target partition includes a first landmark device of the pair and the second partition includes a second landmark device of the pair. The target device is located where the target partitions for the pairs overlap. Network tomography can be applied to increase accuracy.
