  • Patent number: 10721617
    Abstract: To facilitate LWA PDCP setting/scheduling, a method of providing dynamic PDCP status report polling is proposed. To enhance scheduling efficiency, the transmitter (can be eNB from DL or UE for UL) can dynamically poll PDCP status report for LWA behavior. The polling can be done by a standalone PDCP control PDU or use reserved bit in PDCP data PDU. The triggering condition for PDCP status polling includes: PDCP without poll time exceeds a first threshold, PDCP without poll bytes exceeds a second threshold, PDCP without poll PDU numbers exceeds a third threshold, a data buffer is empty, and when LWA is deactivated.

  • Patent number: 10433368
    Abstract: A communications apparatus includes a radio transceiver and a processor. The radio transceiver is configured for transmitting or receiving wireless radio frequency signals to or from a peer device. The processor determines whether re-synchronization in a communication mode with the peer device is required according to a determination rule. When the re-synchronization is required, the processor transmits a message to the peer device via the radio transceiver to trigger a re-synchronization procedure. The processor determines whether the re-synchronization is required in a connected mode.

  • Patent number: 10341394
    Abstract: Aspects of the disclosure provide a method for setting up a call for a user equipment. The method includes receiving, by the user equipment, a measurement configuration message that specifies a set of measurement events corresponding to poor signal quality between the user equipment and a packet-switched network, and sending, by the user equipment, a measurement report when one of the set of measurement events occurs while performing a first call setup process for setting up the call using the packet-switched network. The method also includes terminating the first call setup process after sending the measurement report that indicates poor signal quality between the user equipment and the packet-switched network, and sending, by the user equipment, a service request to begin a second call setup process for setting up the call for the user equipment using a circuit-switched network after terminating the first call setup process.

  • Patent number: 10251098
    Abstract: A user equipment and a circuit-switched fallback method thereof are provided. An initial base station sends a radio resource control connection release message containing the redirection frequency list to the UE. The redirection frequency list includes at least one redirection frequency. The UE determines a priority of the at least one redirection frequency according to a current registered LAI, a learning database and a piece of signal reference information of the redirection frequency list. Accordingly, the UE executes a circuit switch fallback procedure according to the priority of the at least one redirection frequency.

    Abstract: Various solutions for improving data throughput with respect to a multiple subscriber identity module (SIM) user equipment (UE) in mobile communications are described. The UE may perform data transmission associated with a first SIM. The UE may determine whether to suspend a recovery procedure associated with a second SIM according to a condition. The UE may suspend the recovery procedure associated with the second SIM in an event that the condition is satisfied. The UE may further resume the recovery procedure associated with the second SIM when the first SIM enters an idle mode.
