Embodiment 1

[0104] Embodiment 1, NodeB reports data sending and receiving status to RNC through 1 HS-DSCH capability allocation frame:

[0105] Step S02, RNC1 receives UE1's user data from CN1, assuming that all the data in RNC1's buffer has been sent, and VT(A) is 0;

[0106] Step S04, RNC1 divides the user data of UE1 into RLC, and its sequence number is 0 to 15, and according to a certain scheduling algorithm, judges that the capability of NodeB1 is greater than that of NodeB2, and divides the PDUs with sequence numbers 0 to 11 by Figure 9 or Figure 10 Framed and sent to NodeB1, the PDUs with serial numbers from 12 to 15 are pressed Figure 9 or Figure 10 Form a frame and send it to NodeB2, which carries VT(A)=0, and fills in NewIE Flag bit2 with 1;

[0107] Step S06, NodeB1 sends data from the air interface, due to the poor quality of the air interface, PDUs with serial numbers 2, 3 and 7, 8, 9 are discarded on the air interface, and NodeB1 sends the data sending and receiving s...

Embodiment 2

[0111] Embodiment 2, NodeB reports data sending and receiving status to RNC through multiple HS-DSCH capability allocation frames:

[0112] Step S02, RNC1 receives UE1's user data from CN1, assuming that all the data in RNC1's buffer has been sent, and VT(A) is 32;

[0113] In step S04, RNC1 divides the user data of UE1 into RLC, and its serial numbers are 32 to 63, which are evenly distributed to NodeB1 and NodeB2, and 32 to 47 are distributed according to Figure 9 or Figure 10 Frame sent to NodeB1, press 48 to 63 Figure 9 or Figure 10 Send it to NodeB2 in a frame, which carries VT(A)=32, and fills in New IE Flag bit2 with 1;

[0114] Step S06, NodeB1 sends the data from the air interface, sends the sending and receiving status of the data to RNC1 through the HS-DSCH capability allocation frame, AckInd is 1, and Max_Acked_SN is 47;

[0115] Step S08, the air interface quality of NodeB2 suddenly becomes very poor, and a large number of packets are lost (as shown in Tab...

Abstract

The present invention provides a data scheduling processing method and device, the method comprising: Node B receives a downlink data frame sent from a radio network controller RNC, wherein the downlink data frame includes a protocol data unit PDU carrying data; B determines to receive the data sending and receiving status information of the PDU in the downlink data frame; Node B sends the determined data sending and receiving status information to the RNC, wherein the RNC accesses the HSDPA multiplex to the high-speed downlink packet sent to the Node B according to the data sending and receiving status information Flow data is scheduled, and the present invention solves the problem of how to effectively alleviate the above-mentioned "SKEW" phenomenon in the prior art, and then achieves that Node B feeds back the sending and receiving status information of data frames to RNC, thereby guiding RNC to HSDPA multi-flow data The scheduling effectively alleviates the effect of the "SKEW" phenomenon.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a data scheduling processing method and device. Background technique [0002] With the continuous and rapid development of data services, High Speed ​​Packet Access (HSPA for short) technology is becoming more and more common, and it is developing towards the direction of multi-antenna and multi-carrier. For example, the R7 version of 3GPP introduced Multiple Input Multiple Output (MIMO for short) technology, so that NodeB (Node B) can send two transmission blocks from the same cell to UE at the same time through dual antennas; subsequently, 3GPP The R8 version of the new version introduces dual cell HSDPA (Dual Cell HSDPA, referred to as DC-HSDPA) technology, so that NodeB can send HSDPA data to UE from two frequency points of two adjacent cells at the same time. The introduction of these two technologies greatly improves the data throughput of the cell. [0003] When the us...
