Patent ID: 8130721

Claim:
A frequency division duplex (FDD) user equipment (UE) comprising: a radio resource control (RRC) device configured to receive a RRC request message from a radio network controller (RNC) notifying the FDD UE of a high speed dedicated shared channel (HS-DSCH) cell change; a medium access controller-high speed (MAC-hs) circuitry configured to flush its reordering buffers in response to the RRC request message for the HS-DSCH cell change, the MAC-hs circuitry further configured to supply information indicative of the reordering buffers having been flushed; a radio link control (RLC) device configured to autonomously generate a status report for each acknowledge mode (AM) RLC instance mapped to the HS-DSCH and send the status reports to the RNC in response to the MAC-hs flushing the reordering buffers, each status report indicating sequence numbers (SNs) of AM RLC packet data units (PDUs) that are missed and received; and the RRC device configured to send a “TRANSPORT CHANNEL RECONFIGURATION COMPLETE” message on a dedicated control channel (DCCH) after the RLC device generates each status report.
