Abstract
Provided is a method for managing synchronization with a network. The method includes detecting, by a dual SIM dual standby user equipment (a DSDS UE), a radio frequency resume event (an RF resume event); transmitting, by the DSDS UE, at least one uplink dedicated physical control channel (at least one UL-DPCCH) to the network in response to the RF resume event being detected, wherein the at least one UL-DPCCH is transmitted irrespective of a signal to interference ratio quality (an SIR quality) on a downlink dedicated physical control channel (a DL-DPCCH) of the network being below a first quality threshold; and managing, by the DSDS UE, a downlink (a DL) synchronization with the network.
Claims18
A method for managing synchronization with a network, the method comprising:
- detecting, by a dual SIM dual standby user equipment (a DSDS UE), a radio frequency resume event (an RF resume event);
- monitoring a signal to interference ratio quality (an SIR quality) on a downlink dedicated physical control channel (a DL-DPCCH) of the network;
- transmitting, by the DSDS UE, at least one uplink dedicated physical control channel (at least one UL-DPCCH) to the network based on the RF resume event being detected, wherein the at least one UL-DPCCH is transmitted while the SIR quality on the DL-DPCCH is below a first quality threshold;
- and
- managing, by the DSDS UE, a downlink (a DL) synchronization with the network.
A dual SIM dual standby user equipment (a DSDS UE) for managing synchronization with a network, the DSDS UE comprising:
- a transceiver;
- a processor;
- a memory coupled to the processor;
- and
- a synchronization manager coupled to the processor and configured to:
- detect a radio frequency resume event (an RF resume event);
- monitor a signal to interference ratio quality (an SIR quality) on a downlink dedicated physical control channel (a DL-DPCCH) of the network;
- control the transceiver to transmit at least one uplink dedicated physical control channel (at least one UL-DPCCH) to the network based on the RF resume event being detected, wherein the at least one UL-DPCCH is transmitted while the SIR quality on the DL-DPCCH is below a first quality threshold;
- and
- manage a downlink (a DL) synchronization with the network.
A dual SIM dual standby user equipment (a DSDS UE) for managing synchronization with a network, the DSDS UE comprising:
- a transceiver;
- a processor;
- a memory coupled to the processor;
- and
- a synchronization manager coupled to the processor and configured to:
- detect a radio frequency resume event (an RF resume event);
- determine whether at least one buffered downlink protocol data unit (PDU) in radio link control is not associated with a length indicator (an LI);
- control the transceiver to transmit a request for retransmission of at least one PDU subsequent the at least one buffered downlink PDU based on determining the at least one buffered downlink PDU in radio link control is not associated with the LI.
