Abstract: A method for directional signal processing of signals of a microphone array, including first and second microphones generating first and second input signals from an ambient sound, uses the first input signal to form a reference signal transformed into the frequency domain, thereby generating a frequency-space reference signal. The first and second input signals are transformed into the frequency domain, and a first frequency-space directional signal is formed in the frequency domain using the transformed first and second input signals. A frequency-resolved comparison of the frequency-space reference signal with the first frequency-space directional signal or signal derived therefrom in the frequency domain, is used to generate frequency-dependent first gain factors to generate a time filter in the time domain. The reference signal is filtered by the time filter and an output signal is generated from the reference signal filtered by the time filter.

Abstract: This disclosure provides methods, devices, and systems for multi-level configuration and reporting for positioning in new radio (NR) wireless communications systems. In some wireless communications systems, a network entity may determine a position or location of a supported user equipment (UE) using radio access network information. The information may be associated with UE-assisted positioning techniques, such as a positioning reference signal (PRS) transmission by the base station and reporting of radio signaling measurements by the UE. The UE may support a multi-level configuration for reporting the radio signaling measurements, including determined report quantities on one or more of a resource level, a set level, or a setting level for the PRS transmission, or generally for the network entity. The described techniques may improve robustness associated with the reporting and, in some examples, reduce signaling overhead associated with determining a positioning and location of the UE.

Abstract: Disclosed are methods and apparatuses for resolving aliasing ambiguities produced when using channel state information reference signal, a sounding reference signal (SRS) or other transmission as a positioning reference signal (PRS) occupying a subset of tones of a PRS bandwidth. The aliasing ambiguity results in a plurality of different possible positioning measurements, such as time of arrival (TOA), reference signal timing difference (RSTD), or reception to transmission difference (Rx?Tx). The aliasing ambiguity may be resolved using a previous position estimate that may be used to produce an approximation of the expected positioning measurement. A position estimate may be generated using a multiple stage PRS configuration, in which one or more stages provide a coarse position estimate that has no ambiguity, which can be used to resolve the ambiguity of a more accurate position estimate resulting from the PRS signal.

Abstract: The present disclosure relates to computer-implemented methods, software, and systems for obtaining incoming alerts associated with tickets generated for health status issues identified by applications for central components of a cloud platform environment. The obtained incoming alerts are aggregated to determine a root cause ticket. A set of incoming alerts is associated with a first central component running at a first data center from one or more data centers of the cloud platform environment. The set of incoming alerts are generated based on a set of tickets logged at a first ticketing system of the first data center by one or more applications running on the first data center. A root cause ticket is generated to combine the set of tickets corresponding to the set of incoming alerts, and the root cause ticket identifies the first central component as associated with a first health status issue.
