  • Patent number: 12127253
    Abstract: A method for determining Listen Before Talk (LBT) type and Channel Access Priority Class (CAPC) for signaling message transmission over signaling radio bearers (SRBs) in 5G New Radio-Unlicensed (NR-U) is proposed. A user equipment (UE) generates an SRB message to be transmitted to a serving base station over a control channel. Before the uplink (UL) transmission of an UL PDU containing the SRB message, the UE performs an LBT procedure using a set of LBT parameters associated with a CAPC value. In one embodiment, the CAPC is provided by the base station via an UL grant contained in a downlink control information (DCI). In another embodiment, the CAPC is determined by the UE based on an SRB type of the SRB message.

  • Publication number: 20240274100
    Abstract: A frame rate control method is provided. A primary scenario and a non-primary scenario are identified according to two or more windows displayed on a screen. Each of the primary scenario and the non-primary scenario is performed by an individual application. A frame rate of the non-primary scenario is decreased when a performance index indicates that a first condition is present. The application corresponding to the non-primary scenario is disabled when the performance index indicates that a second condition is present after decreasing the frame rate of the non-primary scenario, so as to remove the window corresponding to the non-primary scenario from the screen.

    Abstract: This invention presents methods leveraging artificial intelligence and machine learning (AI/ML) models to enhance wireless communications efficiency in 5G/6G networks. The processes involve storing, configuring, and transferring AI/ML models within base stations and user equipment devices (UE), allowing for localized decision-making and improved network performance. Features include dynamic model activation/deactivation, model compression/decompression, and encoding/decoding method negotiation. Periodic or condition-driven model updates ensure responsiveness to network changes, while model replacements enable upgrades and iterations. The system facilitates seamless handovers between base stations, with information sharing about model capabilities and UE specifics. Model storage and configuration can also occur in the UE, empowering it for local decision-making in variable or challenging network conditions.
