SYSTEM FOR EFFICIENT RECOVERY OF NODE-B BUFFERED DATA FOLLOWING MAC LAYER RESET |
| 摘要 |
A method and system for the UE and RNC to reduce transmission latency and potentially prevent loss of PDUs upon a MAC-hs layer reset. The RNC generates a radio resource control (RRC) message with a MAC-hs reset indication. The MAC reset indication requires the UE to flush buffers for configured HARQ processes, disassemble MAC protocol data units (PDUs) in the reordering buffers, deliver MAC-d PDUs to a MAC-d layer, and configure the MAC-hs to receive new data. |

1. A method for use in a radio network controller (RNC) comprising:
sending a radio resource control (RRC) message to a user equipment (UE) that triggers a high-speed downlink shared channel (HS-DSCH) cell change, wherein the RRC message includes an identifier that a MAC-hs is to be reset, wherein the MAC-hs reset requires the UE to flush MAC-hs packet data units (PDUs) stored in reordering buffers for configured hybrid automatic repeat request (HARQ) processes, disassemble MAC-hs PDUs and deliver the MAC-d PDUs to a MAC-d layer, and configure the MAC-hs to receive new data. |
