Description

High-speed downlink packet access flow control device and method in WCDMA system

Compared to the 3GPP Release 99 version (the "Third Generation Partnership Project" organization published in 1999, the 3GPP Release 5 adds a Media Access Control-High Speed Downlink Packet Access Entity to the Base Station (Node B) ( MAC-HSDPA; MAC-hs). HSDPA's packet scheduler is implemented in MAC-hs. The packet data scheduled by the HSDPA scheduler comes from the Media Access Control of the Radio Network Controller (RNC) - Private (MAC-d) or Media Access Control Entity - Public / Shared (MAC-c/sh). The MAC-d/c/sh data comes from the RNC's Radio Link Control Sublayer (RLC), as shown in Figure 1.

The general procedure for flow control is that MAC-d (or MAC-c/sh) sends a flow control request (HS-DSCH CAPACITY REQUEST) to the MAC-hs based on its buffer status. The MAC hs sends a certain format of the flow control allocation frame (HS-DSCH CAPACITY ALLOCATION) according to the flow control policy, or does not send the flow control allocation frame to let the RNC wait. After receiving the flow control allocation frame, the MAC-d sends a corresponding packet data frame (HS-DSCH DATA FRAME) to the MAC-hs according to a certain policy.

However, the existing traffic control has not yet comprehensively considered the three factors of the RLC mode, the user service type, and the service HS-DSCH cell change, and the UE service is more effectively realized while ensuring the system capacity as high as possible. Continuous processing strategy.

We hope that HSDPA will maintain continuous coverage while providing the highest possible system capacity for WCDMA systems. For example, it is covered with the 3GPP Release 99 cell. Techniques such as power control, adaptive modulation coding (AMC), hybrid automatic repeat request (HARQ), channel switching (such as HS-DSCH and DCH switching, or HS-DSCH and FACH switching) can do this.

When the UE approaches or reaches the cell edge, the common pilot channel (CPICH), the downlink dedicated control physical channel (DL-DPCCH), and the high-speed shared control channel (HS-SCCH) have high reliability due to processing gain. Very big. The high-speed downlink shared physical channel (HS-PDSCH) has lower reliability of correct decoding due to smaller processing gain. In order to keep the UE's service continuous when the UE moves to the cell edge, we can adopt two effective methods: lower the UE's service rate (throughput rate) by MAC, and improve the channel time. Or; to switch the service on the HS-DSCH to the DH through the channel switching technology, and maintain the continuity of the UE service by using the fast power control of the DCH, the soft handover, and the like. Either way, the Radio Link Control-No Acknowledgement Mode (RCC-UM) data that has been transmitted to the MAC-hs but has not been successfully received by the UE will be lost. Radio Link Control-Acknowledgment Mode (RLC-AM) data is not affected.

The present invention mainly focuses on predicting the type of service of the UE and predicting the possibility of the UE performing the service HS-DSCH cell change in time. This not only ensures the continuity of the UE service, but also maximizes the system capacity.
