  • Publication number: 20250251828
    Abstract: A touch sensing reading device includes an operation circuit and an adjustment circuit. The operation circuit includes a feedback capacitor, receives a sensing signal through a first input terminal, receives a driving signal through a second input terminal, and feedbacks an output signal via an output terminal through the feedback capacitor and the first input terminal. The adjustment circuit provides an adjustment signal to the first input terminal of the operation circuit, and adjusts the output signal. A first sub-signal in the adjustment signal is set based on the inverted signal of the driving signal. A second sub-signal in the adjustment signal is set based on the inverted signal of the sensing signal.

  • Patent number: 12382545
    Abstract: Apparatus and methods are provided for reliable multicast transmission with compact protocol stack. In one novel aspect, compact protocol stacks are configured for the UE and the base station handling both the PTM RB and the PTP RB. The compact protocol stack is either configured a compact RLC entity or a compact PDCP entity. The UE monitors a PTM LCH and a PTP LCH and sends feedback to the network with the PTP RB. The base station transmits MBS data packets in the PTM mode to the one or more subscriber UE, monitors feedback report from each subscriber UEs through corresponding PTP RB, and retransmits MBS data packets to one or more UEs through corresponding PTP RBs based on corresponding feedback reports. PTM-to-PTP and PTP-to-PTM mode switches are performed when triggering events are detected. The mode switch notification is sent to UEs via MAC CE or RLC control PDU.

  • Publication number: 20250247754
    Abstract: Methods for a New Radio (NR)-based, Low Earth Orbit (LEO) Non-Terrestrial Networks (NTN) are proposed to improve cell selection and reselection by using satellite assistance information. Different from traditional 5G New Radio systems, the LEO NTN can provide the next cell information along the satellite trajectory using System Information Broadcast (SIB). The assistance information can include satellite's long term ephemeris in the format of Position Velocity (PV) information or details of satellite's other orbital parameters. During TN-NTN join coverage, as TN cells are expected to have a better coverage then NTN cells, the network can assign higher priority to the TN cells over NTN cells. Similarly, for a mobility involving earth-fixed and earth-moving beams (cells), earth-fixed cells can be prioritized over earth-moving beams for cell reselection.

  • Publication number: 20250216589
    Abstract: A display panel including a first substrate, a pixel-array layer, and a color-resist layer is disclosed. The pixel-array layer includes multiple first signal lines, multiple second signal lines, and multiple third signal lines. Each of the first signal lines corresponds to a common border between multiple first color resists and multiple second color resists. Each of the second signal lines corresponds to a common border between multiple third color resists and multiple first color resists. Each of the third signal lines corresponds to a common border between multiple second color resists and multiple third color resists. Reflected light coming from the first signal lines, reflected light coming from the second signal lines, and reflected light coming from the third signal lines are mixed to form white light.

  • Patent number: 12342406
    Abstract: Apparatus and methods are provided for connectionless data transfer. In one novel aspect, the UE in INACTIVE state initiates one or more data transmissions without RRC connection upon determining one or more preconfigured transmission conditions. The UE restores an INACTIVE AS context, establishes UL resources, and performs connectionless data transmissions. The UE monitors one or more preconfigured fallback conditions for fallback procedures and monitors stop conditions for suspension/stopping procedures. In one embodiment, the UL resources for the one or more data transmission are preconfigured configuration grant (CG) resources from the network. In one embodiment, the preconfigured UL resource is used for the data transmission only when the TA is valid. When the TA is not valid, the UE performs RA procedure and either uses the preconfigure resource or continues the one or more data transmissions by monitoring PDCCH with C-RNTI.

  • Patent number: 12335800
    Abstract: Methods and apparatus are provided for UE-triggered handover and early preparation with coexistence of the network-triggered handover. In one novel aspect, the UE is configured early measurement report configuration, receives an early handover command from the serving base station with a handover candidate cell list, monitors handover triggering conditions for each candidate cell on the handover candidate cell list based on a UE-triggered handover configuration and performs the UE-triggered handover to a candidate cell when the corresponding triggering condition is met for the candidate cell. In one embodiment, the UE receives a network-triggered handover command to a target cell, suspends the UE-triggered handover configuration and performs the network-triggered handover to the target cell. The UE discards the UE-triggered handover configuration upon success of the network-triggered handover and resumes the UE-triggered handover configuration upon failure of the network-triggered handover.

  • Patent number: 12317146
    Abstract: A method of configuring a set of active cells among neighboring cells to reduce latency and interruption for inter-cell mobility is proposed. The set of active cells is an active set of cells among which UE can do fast cell switching. The set of active cells is configured by the network based on UE measurement report or network deployment information. UE maintains the configuration and can perform pre-synchronization to the configured active cells in downlink (DL) only or in both DL and uplink (UL). UE maintains the DL/UL synchronization with the active cells, and applies configuration once UE is indicated to switch to an active cell as the target cell. Because UE maintains the configuration and DL/UL timing of the target cell before receiving the cell-switch command, the mobility latency and interruption time for inter-cell mobility is reduced.

  • 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.
