Abstract:
1. A user equipment (UE) comprising: a reordering buffer of a medium access control-high speed (MAC-hs) circuitry, wherein the reordering buffer is flushed in response to receiving a radio resource control (RRC) request message from a Remote Network Controller (RNC) indicative of a high speed-downlink shared channel (HS-DSCH) cell change; and a radio link control (RLC) device having at least one acknowledge mode (AM) RLC instance mapped to the HS-DSCH, wherein the MAC-hs circuitry informs the RLC device to generate a status report in response to the reordering buffer being flushed, wherein the RLC device autonomously generates a status report for each AM RLC instance in response to the MAC-hs flushing the reordering buffer and sends the status report to the RNC, the status report indicating sequence numbers (SNs) of AM RLC packet data units (PDUs) that are missed and received by the UE.
