Patent ID: 8085726

Claim:
A user equipment (UE) which facilitates a high speed-downlink shared channel (HS-DSCH) cell change, the UE comprising: circuitry configured to receive a wireless signal, the wireless signal carrying a radio resource control (RRC) request message from a Remote Network Controller (RNC) indicative of the HS-DSCH cell change; high speed medium access control (MAC-hs) circuitry; reordering buffers associated with the MAC-hs circuitry; circuitry configured to flush the reordering buffers in response to receiving 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; and radio link control (RLC) circuitry configured to autonomously generate status reports in response to the MAC-hs flushing the reordering buffers and send the status reports to the RNC, each of the status reports corresponding to a respective one of acknowledge mode (AM) RLC instances mapped to the HS-DSCH, the status reports indicating sequence numbers (SNs) of AM RLC packet data units (PDUs) that are missed and received by the UE.
