Abstract
A method and apparatus for radio resource control (RRC) state transitions of a user equipment (UE) are provided. For the RRC state transitions of the UE, for example, a reconfiguration message is received at the UE while the UE is in a cell dedicated channel (CELL_DCH) state of the RRC states. The reconfiguration message is configured to transition the UE from the CELL_DCH state to a non-dedicated channel state of RRC states. A plurality of acknowledgement procedures is sent on an uplink to the network, in response to the received reconfiguration message causing the UE to transition from the CELL_DCH state to the non-dedicated channel state.
Claims20
A method of transitioning radio resource control (RRC) states of a user equipment (UE) for wireless communications, comprising:
- receiving a reconfiguration message from a network, while the UE is in a cell dedicated channel (CELL_DCH) state of the RRC states, wherein the reconfiguration message is configured to transition the UE from the CELL_DCH state to a non-dedicated channel state of the RRC states;
- and
- sending a plurality of acknowledgement procedures to the network on an uplink, in response to the received reconfiguration message causing the UE to transition from the CELL_DCH state of the RRC states to the non-dedicated channel state of the RRC states,
- wherein a number of the plurality of acknowledgement procedures is determined based at least on previous RRC state transitions of the UE, and
- wherein each of the plurality of acknowledgement procedures comprises a same status packet data unit (PDU), and each of the same status PDU includes acknowledgement information of the received reconfiguration message from the network.
An apparatus for transitioning radio resource control (RRC) states of a user equipment (UE) for wireless communications, comprising:
- means for receiving a reconfiguration message from a network, while the UE is in a cell dedicated channel (CELL_DCH) state of the RRC states, wherein the reconfiguration message is configured to transition the UE from the CELL_DCH state to a non-dedicated channel state of the RRC states;
- and
- means for sending a plurality of acknowledgement procedures to the network on an uplink, in response to the received reconfiguration message causing the UE to transition from the CELL_DCH state of the RRC states to the non-dedicated channel state of the RRC states,
- wherein a number of the plurality of acknowledgement procedures is determined based at least on previous RRC state transitions of the UE, and
- wherein each of the plurality of acknowledgement procedures comprises a same status packet data unit (PDU), and each of the same status PDU includes acknowledgement information of the received reconfiguration message from the network.
A user equipment (UE) for wireless communications, comprising:
- a receiver configured to receive a reconfiguration message from a network, while the UE is in a cell dedicated channel (CELL_DCH) state of radio resource control (RRC) states, wherein the reconfiguration message is configured to transition the UE from the CELL_DCH state to a non-dedicated channel state of the RRC states;
- and
- a transmitter configured to send a plurality of acknowledgement procedures to the network on an uplink, in response to the received reconfiguration message causing the UE to transition from the CELL_DCH state of the RRC states to the non-dedicated channel state of the RRC states,
- wherein a number of the plurality of acknowledgement procedures is determined based at least on previous RRC state transitions of the UE, and
- wherein each of the plurality of acknowledgement procedures comprises a same status packet data unit (PDU), and each of the same status PDU includes acknowledgement information of the received reconfiguration message from the network.
A non-transitory computer readable medium storing computer executable code, comprising:
- code for receiving a reconfiguration message from a network, while a user equipment (UE) is in a cell dedicated channel (CELL_DCH) state of radio resource control (RRC) states, wherein the reconfiguration message is configured to transition the UE from the CELL_DCH state to a non-dedicated channel state of the RRC states;
- and
- code for sending a plurality of acknowledgement procedures to the network on an uplink, in response to the received reconfiguration message causing the UE to transition from the CELL_DCH state of the RRC states to the non-dedicated channel state of the RRC states,
- wherein a number of the plurality of acknowledgement procedures is determined based at least on previous RRC state transitions of the UE, and
- wherein each of the plurality of acknowledgement procedures comprises a same status packet data unit (PDU), and each of the same status PDU includes acknowledgement information of the received reconfiguration message from the network.
