The new cell (Information Elements IEs) of " residue is extended " territory indication backwards compatibility mode is with the position that increases.The length in this territory is 0～32 byte.

9, payload CRC (optional)

" payload CRC " territory is the CRC check of payload.This CRC is the remainder that is applied to payload, 0 of the bit of the payload before promptly from 7 of the bits of first byte of payload to payload CRC.Length is 16 bits.

If the E-DCH payload is successfully decoded, then fill in the E-DCH Frame according to above-mentioned form, send to SRNC by Node B.

The decoding if the E-DCH payload gets nowhere, and satisfy following arbitrary condition, serving node B will send the HARQ failure and indicate to SRNC (non-serving node B will not send HARQ failure indication):

Condition 1: for a HARQ process, MAC-e or MAC-i protocol Data Unit can not successfully be decoded, and re-transmission sequence number (Retransmission Sequence Number, RSN) new MAC-e of indication or MAC-i protocol Data Unit transmit and are used for identical HARQ process, and the HARQ retransmission number that has taken place is equal to or higher than the minimum that terminal has disposed the maximum HARQ re-transmission value of MAC-d stream.

Condition 2: MAC-e or MAC-i for some HARQ processes are never successfully decoded, and terminal connects the maximum retransmit generation of the MAC-d stream of maximum re-transmission of effective the highest harq hereto, perhaps be correlated with out-of-band signalling (such as re-transmission sequence number for HARQ on E-DPCCH, RSN) under can not the decoding situation, the terminal maximum retransmit that connects the MAC-d stream that effectively the highest harq retransmits for maximum time should be able to take place hereto.

Condition 3: when MAC-e or MAC-i are reset at terminal and carry out, never successfully decoded for the MAC-e or the MAC-i of some HARQ processes.Node B is known lane terminal MAC-e or MAC-i replacement time point by high level.

HARQ failure indication only is sent out at a transmission bearer.Any one transmission bearer that Node B selects the terminal relevant with this HARQ failure indication to interrelate.

HARQ failure is instructed in user data frame, is called HARQ failure designation data frame, specifically be provided with as follows, as shown in Figure 2:

1, be detected when failure, Connection Frame Number and subframe numbers cell value will reflect this time point.

2, in the Class1 structure: the number of MAC-es protocol Data Unit will be set to 0.The cell that in head, does not correspondingly have DDI and N.For 8 bit aligned, 4 fillers are used behind MAC-es protocol Data Unit cell, and the payload part of the Frame relevant with the HARQ failure does not have the MAC-es protocol Data Unit yet.

3, in type 2 structures: the number of MAC-is protocol Data Unit will be set to 0.In head, correspondingly there is not MAC-is protocol data descriptor cell.The payload part of the Frame relevant with the HARQ failure does not have the MAC-is protocol Data Unit.

4, the cell of HARQ re-transmission number will be set at the failure detection HARQ number of retransmissions that has taken place then.Coded system is with to be correctly decoded the payload coded system as previously described the same.

SRNC decodes the input of HARQ number of retransmissions as external circule power control from being correctly decoded of receiving the E-DCH Frame frame head, or decodes the input of HARQ number of retransmissions as external circule power control from HARQ failure indication E-DCH Frame frame head.If (SignalInterference Ratio SIR) revises the output signal-to-noise ratio of external circule power control, and SRNC comprises that new sir target sends to Node B in the exterior ring power control frame.The inner loop power controlled function that is positioned at Node B will use new sir target to carry out the power emission of control terminal, thereby reach minimise interference and keep quality of connection.

Along with technical development, two ZAP (this technology makes terminal to send data on two carrier waves, thereby makes uplink data rate be doubled) wish to be introduced into existing system, if use current HARQ failure indication, following point will occur:

Because Node B is received the situation from the MAC-es PDU or the MAC-is PDU of two carrier waves, the situation of two data decodes failures on the carrier wave can appear simultaneously, or success and the situation of another failure; And HARQ failure indication of the prior art is the situation at the decoding failure of MAC-es PDU on the carrier wave or MAC-is PDU.If Node B has a failure from the MAC-e PDU or the MAC-i PDU of two carrier waves, or two all failed, enter HARQ failure designation data frame, i.e. the decoding of MAC-e PDU on two carrier waves or the MAC-i PDU just shared HARQ failure designation data frame of failing.And external circule power control (Outer Loop Power Control OLPC) is based on that the HARQ data retransmission of the HARQ data retransmission of E-DCH frame protocol data frame frame head or HARQ failure designation data frame frame head calculates.Present HARQ failure designation data frame can't inform which carrier wave the HARQ number of retransmissions belongs to, and SRNC also just can't know the number of retransmissions of data flow on each carrier wave, thereby can't be OLPC.
