Abstract: A method performed by a network node for detecting bandlimited interference in a single-carrier Uplink (UL) from a User Equipment (UE) in a wireless communications network is provided. The network node receives (201) a data sequence of the single-carrier UL. The network node defines (202) a kernel-based statistical two-sample test, forming a squared Maximum Mean Discrepancy, MMD, distance-measure. The network node obtains (203) a first sequence Y. The first sequence Y comprises a sequence of an integer of N samples comprising ideal UL data of a given configuration associated to characteristics of the single-carrier UL. The network node further obtains (204) a second sequence X, which second sequence X comprises a sequence of the integer of N samples from the received data sequence. The network node decides (206) whether or not bandlimited interference is present in the single-carrier UL, based on comparing (205) the first sequence Y with the second sequence X according to the defined kernel-based statistical two-sample test.

Abstract: A method for root cause analysis in a network comprising a set of nodes Ni for i=1 to N, where N > 2. The method includes obtaining N sets of KPI data, each one of the N sets of KPI data being for one of the N nodes. The method also includes, for each one of the N nodes, using the set of KPI data associated with the node to generate feature vectors for the node. The method also includes generating relationship data using the feature vectors, the generated relationship data, indicating relationships between the nodes within the set of N nodes. The method also includes inputting to a GNN the generated relationship data and the feature vectors. The method also includes obtaining from the GNN information indicating that at least node Nj is a candidate root cause node and at least node Nk is a candidate victim node, where k ≠ j. The method further includes using the relationship data to i) determine whether to indicate the candidate root cause node Nj as a predicted root cause node and/or ii) determine whether to indicate the candidate victim node Nk as a predicted victim node.

Abstract: Embodiments disclosed herein relate to methods and apparatus for managing a sensor grid system including configuring and using sensor grids for various tasks. In one embodiment there is provided a method of configuring a sensor grid system (100) having a plurality of sensors (110, 310) arranged to collect data from a working space. The method comprises applying an output from the sensors to a task model (230, 350-1 – 350-4) for performing a task associated with the working space (250). A task accuracy parameter is corresponding to the accuracy with which the task model performs the task is determine. In response to the task accuracy parameter (365) being below a task accuracy parameter threshold (375), the resolution of the output from the sensors (270) is increased, and the complexity of the task model (280) is increased.

The method further includes deciding (703) an importance of the test case based on the value. The method further includes ranking (705) the test case based on the decision; and outputting (707) a test plan based on the ranking of the test case.
