Abstract
A radio resource control (RRC) message is received by a radio resource control (RRC) device of a user equipment (UE). The RRC message notifies the FDD UE of a high speed dedicated shared channel (HS-DSCH) inter-Node B cell change. A reordering buffers of a medium access controller-high speed (MAC-hs) is flushed in response to the receiving the RRC message. A status report is generated for each acknowledge mode (AM) RLC instance mapped to the HS-DSCH by a radio link control (RLC) device after the MAC-hs flushes the reordering buffer. Each status report indicates missing AM RLC packet data units (PDUs). The RRC device sends a “TRANSPORT CHANNEL RECONFIGURATION COMPLETE” message on a DCCH after the RLC device generates each status report.
Claims8
A user equipment (UE) comprising:
- transmitting and receiving components configured to receive a radio resource control (RRC) handover message from a source NodeB;
- wherein the components are further configured, in response to the RRC handover message, to initiate handover to a target NodeB;
- wherein the components are further configured, in response to the RRC handover message in an initial uplink data transmission to the target NodeB, to transmit a second RRC message along with a status report associated with at least one buffer of the UE.
A method comprising:
- receiving, by a user equipment (UE), a radio resource control (RRC) handover message from a source NodeB;
- in response to the RRC handover message, initiating, by the UE, a handover to a target NodeB;
- in response to the RRC handover message, transmitting, by the UE in an initial uplink data transmission to the target NodeB, a second RRC message along with a status report associated with at least one buffer of the UE.
