  • Patent number: 11051362
    Abstract: A user equipment (UE) and a base station (BS) for a mobile communication system are provided. The UE performs a random access (RA) procedure with the BS in a radio resource control (RRC) idle mode. The UE transmits a preconfigured uplink resource request message to the BS and receives a configuration message indicating a preconfigured uplink resource from the BS. The UE starts a time alignment timer (TAT) which is used for the RRC idle mode in response to the RA procedure. When the UE determines that there exists an uplink message to be transmitted in the RRC idle mode and determines that the current timing advance (TA) value is valid, the UE transmits the uplink message on the preconfigured uplink resource.

  • Patent number: 10860151
    Abstract: A capacitive touch sensor includes sensing columns. Each sensing column has a common sensing electrode and driving electrodes. The driving electrodes are divided into two groups, which are connected to contacts in two bridging areas through electrode wires. Each bridging area is covered by an insulation film with through holes corresponding to the contacts. Signal wires of the driving electrodes pass through the through holes to connect the contacts of the driving electrodes of the sensing columns, which are located in a line, to form a signal channel. The signal wires connecting the common sensing electrodes pass through one of the two bridging areas and insulatively intersect the signal wires of the driving electrodes of the signal channel. Electrode extending portions of the common sensing electrodes are extended to the other bridging area to insulatively intersect signal wires of the driving electrodes of the signal channel.
