In some embodiments, a method of analyzing a signal for a spectrum anomaly includes: obtaining an uplink signal for a predetermined time period; generating a spectrogram from the uplink data for the predetermined time period; analyzing the spectrogram using a spectrum anomaly Neural Network (NN) model; and determining, based on the results of the analysis, whether the uplink signal comprises a spectrum anomaly. In some embodiments, Machine Learning Spectrogram Analysis does not use pre-deterministic criteria and Passive Inter-Modulation (PIM) models. In some embodiments, a NN/ Convolutional NN (CNN) does spectrogram analysis as "image" analysis. In this way, spectrum anomaly and PIM detection can be performed more precisely for different use case scenarios such as dual/triple/quad band radio, etc.

Various embodiments of the present disclosure provide for a method and apparatuses that perform spatial encoding in a multipath environment such that transmissions on different beams are separately encrypted with complex codes such that when the transmissions on the different beams are received at the receiver, the separate encryptions are cancelled out. The transmissions can also have time delay, gain, and phase modifications made to the transmissions such that the automatic self-decryption is performed within a predefined distance of where the receiver is determined to be. In this way, encryption/decryption keys do not have to be sent to the receiver, and unauthorized devices that intercept the beams at a location other than the receiver location will not be able to decrypt the communication.

Some solutions proposed allow the possibility for the network and the UE to support cases with Doppler domain compression and without Doppler domain compression under a single CSI reporting framework. Based on the signaling received from the network, the solutions allow the UE to determine when to feedback selected Doppler domain bases and when to avoid Doppler domain bases selection in the Type II CSI report.

Abrégé

A Multiple-Input Multiple Output (MIMO) device (200) determines a minimum output vector produced by a quadratic unconstrained minimization function. The quadratic unconstrained minimization function comprises a peak power factor, an average power factor,an Error Vector Magnitude (EVM) constraint factor for meeting an EVM constraint, and a plurality of penalty coefficients that penalizes outcomes that violate the EVM constraint. TheMIMO device (200) minimizes the peak power factor and maximizes the average power factor. The minimizing and maximizing are each performed within the EVM constraint. The MIMO device (200) derives a Quantum Unconstrained Binary Optimization (QUBO) from the minimum output vector. The MIMO device (200) then configures the quantum precoder (210) to generate a configuration of qubits that are representative of a precoding vector that meets the EVM constraint and minimizes Peak to Average Power Ratio (PAPR) of a transmission from the MIMO device (200). The configuring comprises embedding the QUBO on the quantum precoder (210).

Techniques disclosed herein efficiently address prioritization by a UE regarding its reception behavior with respect to a configured downlink transmission that is overlapped by a dynamic assignment and/or the dynamic downlink transmission scheduled via the dynamic assignment. In at least one embodiment having applicability to operation of the UE in a communication network based on the 5G NR specifications, the techniques disclosed herein provide for predictable behavior by the UE as to when the UE prioritizes a configured Physical Downlink Shared Channel (PDSCH) versus another PDSCH. Correspondingly, a radio network node may exploit the predictable behavior of the UE to override a configured PDSCH in favor of a dynamic PDSCH, by transmitting the Physical Downlink Control Channel (PDCCH) that schedules the dynamic PDSCH so that a timing relationship between the PDCCH and the configured PDSCH is satisfied.

Abrégé

In various embodiments of the present disclosure, provided is a system to perform reduced complexity frequency selective linearization. In an embodiment, multistage digital predistortion (DPD) can linearize different parts of the spectrum differently. The first stage captures the signal across the entire linearization bandwidth where the least stringent linearization requirement and general unwanted emission requirements are targeted. Second stage pre-distorts a down-sampled signal where second least stringent requirements across the linearization bandwidth are aimed for. This "peel-off'' process continues until the final stage which pre-distorts the portion of the spectrum with the most stringent linearization requirements. Consequently, earlier stages run at higher rates to linearize wider spectrum while later stages run at lowerrates to selectively further linearize portions of spectrum that have already passed through earlier stages.

Abrégé

A management system (200) configures logging in telecommunication networks executing one or more services (230) in a distributed workflow. To accomplish its function, the management system obtains vulnerability information for one or more services currently deployed in a communications network. The vulnerability information comprises, for each of the one or more services a vulnerability identifier (VID) identifying a vulnerability of the service and a vulnerability score indicating a severity of the vulnerability. So obtained, the management system configures a logging framework (220) to generate trace records (406, 424) for a service currently deployed in the communications network to include the VID and the vulnerability score of the service. The management system configures the logging framework to generate the trace records on a use case basis. Therefore, each of the trace records are generated to identify a particular use case and use case instance associated with the execution of the service.

Abrégé

In various embodiments disclosed herein, a method and architecture for a Sensing Management Function (SeMF) is provided to enable the network to perform sensing and localization to provide accurate positioning while also efficiently using network resources. The SeMF can configure sensing nodes (e.g., base stations, Transmission Reception Points (TRPs) and User 5 Equipment devices (UEs)) to perform sensing, and based on the sensing data and other information, send a trigger to a Location Management Function (LMF) to initiate localization. Likewise, the LMF can perform localization, and based on the location data, or Quality of Service (QoS) requirements, also send a trigger to the SeMF to initiate sensing. Additionally, disclosed is a method for configuring the sensing nodes to perform sensing. 0
