  • Publication number: 20230359725
    Abstract: Methods and systems for monitoring the behavior of a process. A profile of a software module is obtained. An association request is received from a process. The association request includes an identifier. In response to receiving the association request, successfully validating the identifier based on the profile and establishing an association of a token to data associated with the identifier.

  • Publication number: 20230345494
    Abstract: Uplink control channel resource allocation for an enhanced downlink control channel is disclosed. A first example method disclosed herein includes receiving, at a user equipment (UE), a downlink control channel carrying a physical uplink control channel (PUCCH) resource indicator, mapping the PUCCH resource indicator to a first offset, mapping a position of the downlink control channel to a second offset, and mapping a linear combination of the first and second offsets to an index identifying a first PUCCH resource. A second example method disclosed herein includes, in response to receiving, at a UE, an indication of a dynamic resource offset in an enhanced physical downlink control channel (ePDCCH) transmitted in a first ePDCCH set, determining a position of the ePDCCH and a subframe offset, and processing the indication of the dynamic resource offset, the position and the subframe offset to determine an allocated uplink control channel resource for the UE.

  • Publication number: 20230335106
    Abstract: Systems and methods are disclosed for identifying at least one cause of noise in a vehicle audio system. The vehicle audio system may include a plurality of audio channels. Acoustic output may be generated and received through each of the audio channels. Acoustic input may be received from one or more of the audio channels and may be processed to generate processed acoustic input. The processed acoustic input may include a frequency response of the acoustic input. The processed acoustic input may be compared to corresponding channel target input and at least one deviation may be determined. A cause of the at least one deviation may then be determined based on a relationship between the at least one deviation and a set of resolved indications of cause, each of the set of resolved indications of cause corresponding to at least one of a set of recorded causes.
