Abstract:
1. A method for use a radio network controller (RNC), the method comprising: sending a message to a user equipment (UE) providing information for a HS-DSCH cell change; sending a radio resource control (RRC) message to the UE, the RRC message having an identifier indicating that a MAC-hs is to be reset; receiving one or more radio link control (RLC) status report from the UE, wherein the RLC status report indicates the status of RLC protocol data units (PDUs) received by the UE; wherein the HS-DSCH cell change is triggered based on the sent RRC message; and wherein the MAC-hs reset requires the UE to flush buffers for configured HARQ processes, disassemble MAC-hs protocol data units (PDUs) in the reordering buffers, deliver MAC-d PDUs to a MAC-d layer, flush reordering buffers and configure the MAC-hs to receive new data.
