Abstract: A method for mitigating interference in a wireless communication system includes receiving a signal transmitted from a mobile station, subtracting a target signal within a target bandwidth (BW) from the received signal to obtain a resultant signal, wherein the target signal is constructed by estimating a target channel and target symbols from the signal, determining a subspace blind interference sensing (BIS) BW by extending resource blocks (RBs) prior to a starting RB and after an ending RB of the target bandwidth using energy detection in each RB, determining a set of candidate interfering BWs in the subspace BIS BW by determining the number of interferers in each RB in the subspace BIS BW, and determining a set of candidate interfering DMRS sequences based on the set of candidate interfering BWs by performing DMRS detection for each candidate interfering BW.

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.
