Abstract: Apparatuses and methods for identifying network anomalies. A method includes determining a cumulative anomaly score over a predefined time range based on a subset of historical PM samples and determining an anomaly ratio of a first time window and a second time window, based on the cumulative anomaly score. The method also includes determining one or more anomaly events coinciding with CM parameter changes based on the anomaly ratio; collating the PM, alarm, and CM data into a combined data set based on matching fields and timestamps; generating a set of rules linking one or more CM parameter changes and the collated data to anomaly events; and generating root cause explanations for CM parameter changes that are linked to anomaly events.

Abstract: A method includes partitioning a set of configuration management (CM) data for one or more cellular network devices into multiple distinct time intervals, each time interval associated with a distinct set of CM settings at the one or more cellular network devices, the CM data comprising multiple CM parameters. The method also includes determining a regression model based on the set of CM data. The method also includes applying the regression model to compute a distinct set of scores and compare the set of scores to estimate whether a performance of the one or more cellular network devices has changed during a second time interval relative to a first time interval.

Abstract: Methods and apparatuses for resource allocation and timing handling in a wireless communication network. A method of operating a base station (BS) in the wireless communication network includes communicating with at least a first parent BS of the BS in the wireless communication network according to a slot pattern of the BS. The slot pattern indicates slots on which the BS can receive and slots on which the BS can transmit. The method further includes receiving discovery information about a neighbor BS in the wireless communication network and determining whether to add the neighbor BS as a second parent BS of the BS based on the discovery information about the neighbor BS. The method further includes determining a resource allocation to the second parent BS based on the slot pattern of the BS and communicating with the second parent BS based on the determined resource allocation.
