The HSDPA transmission of existing 1.28M TDD (Time Division Duplex, time division duplex) pattern, it is the HS-SCCH of its configuration that UE (User Equipment, subscriber equipment) continues to monitor network equipment.No matter be to transmit first or retransmit, its transmission course is:
When network equipment sends descending enhancing data will for certain UE, at first send HS-SCCH, modulation system, transmission block size, HARQ (Hybrid Automatic Repeat request that the physical resource that HS-PDSCH takies, this transmission are adopted have been carried on it, mix automatic repeat requests) indication of information, new data and UE ID (Identifier, identifier) etc.Receive and decoding HS-SCCH in case UE is correct, will on corresponding physical resource, receive the HS-PDSCH data, and feeding back ACK or NACK (no response of feedback error indication) message and CQI message on HS-SICH subsequently.Wherein, what HS-SCCH took is that two spreading factors are the code channel of 16 (being SF16), comprise on one of them code channel and be used for HS-SICH power control and synchronous TPC (Transmission Power Control, the transmission power control command word) and SS (Synchronization Shift, synch command word) order.HS-PDSCH does not adopt power control.HS-SICH takies the code channel of a SF16, comprising being used for HS-SCCH power control and synchronous TPC and SS order.
HSUPA (High Speed Uplink Packet Access, high-speed uplink packet access technique) uplink physical channel in is E-PUCH (E-DCH Physical UPlink Channel, E-DCH physical uplink channel, wherein E-DCH is Enhanced Dedicated Transport Channel, the dedicated transmission channel of enhancing).Transmission channel E-DCII and E-UCCH (E-DCH Uplink Control Channel, the E-DCH ascending control channel) data multiplex is mapped on the E-PUCH together, wherein, E-DCH has carried uplink strengthening data, and the E-UCCH carrying is the relevant signaling of HARQ.The E-UCCH loaded information comprises: TBS (Transport-block Size, transmission block size) (6 bit), HARQ process number (2 bit) and RSN (Retransmission Sequence Number, re-transmission sequence number) (2 bit).The transfer of data of HSUPA is divided into scheduled transmission and non-scheduled transmission.Wherein, non-scheduled transmission is meant that system has reserved the certain physical resource for UE in advance, and by high-level signaling notice UE, UE no longer sends dispatch request and receives E-AGCH (E-DCH Absolute Grant Channel before each transmission, the E-DCH absolute grant channel), but on reserved resource, directly send uplink strengthening data, and go up the reception feedback message at E-HICH (E-DCHHybrid ARQ Indicator Channel, E-DCH confirms indicating channel).
The deficiencies in the prior art are:
According to existing HSDPA transmission mechanism, all need the HS-SCCH of transmission two code channels earlier in each initial transmission and before retransmitting, the control information that the notice terminal is correlated with sends data again.To also will be on HS-SICH after the data decodings feeding back ACK and CQI.Expenses of these control signalings change smaller small data packets business for code check, are very large as VoIP (Voice over IP, IP-based voice transfer) etc.

Adopt the basic transmission block size of high-rise notice to carry out blind decoding during the UE decoding.Carried UE ID on the CRC of HS-PDSCH (Cyclic Redundancy Check, cyclic redundancy check (CRC)).The control information of feeding back ACK in case the UE decoding is correct; If the decoding failure then saves the data in the buffer memory.
Step 104, when network equipment needs through the HS-PDSCH data retransmission, receive the control signaling through HS-SCCH channel indication subscriber equipment.
The reception information of the data that described control signaling packet includes network side apparatus will retransmit on HS-PDSCH.During re-transmission, network equipment at first sends control signaling by HS-SCCH, carried the reception information of data on HS-PDSCH when retransmitting on it, as: the physical resource that takies, transmission block size, to be used to indicate be to previous which TTI (Transmission Time Interval, Transmission Time Interval) PTR (the Previous Tx point that retransmits of data, last time transmitted pointer), HCSN (HS-SCCH cyclic sequencenumber, HS-SCCH cyclic sequence number) and UE ID.
Step 105, subscriber equipment receive the control signaling of network equipment indication, and carry out Data Receiving according to control command.
Step 106, subscriber equipment through E-UCCH to the network equipment feedback control information.
Described control information comprises that subscriber equipment receives the state information that described network equipment sends data on HS-PDSCH.
After network equipment sent the data that retransmit by HS-PDSCH, UE received data and decodes, and control informations such as feeding back ACK or NACK.
In the above-described embodiments, include the upstream data control information of going up data at E-PUCH in the control information, as: the identification information TBS of transmission block size, HARQ process number, transmission first or the identification information NDI (New Data Indicator, new data indication) that retransmits, simultaneously also comprised at whether transmitting of data control information on the HS-PDSCH channel correct reply identification message ACK/NACK etc.
Further, can also comprise transmission power control command word TPC in the control information, TPC is used for as network equipment HS-PDSCH being carried out the foundation of power control.
Control information to the UE feedback is further detailed below.
Small data packets transport service in little code check variation, as VoIP business etc., this class business has characteristics such as the packet size is comparatively fixing, real-time is had relatively high expectations, according to characteristics such as this class business characteristic of VoIP and up-downgoing exist simultaneously, can be optimized the control information that E-UCCH goes up carrying.

The present invention is directed to the VoIP business characteristic, the control information that E-UCCH is carried is revised as:
TBS: because the less variation of the transmission block that VoIP needs size so can reduce the bit number of TBS, is for example only used 2 bits;
The HARQ process number: in asynchronous HARQ, re-transmission can occur in any time, and parallel simultaneously a plurality of HARQ processes is arranged, and therefore need be distinguished with the number of carrying out.And the employing synchronous HARQ occurs in the predefined moment owing to retransmit, promptly can distinguish, thereby no longer needed process number from the time, so this information actual be 0 bit;
NDI: only need be used for indication is to transmit first or retransmits, and therefore only need 1 bit gets final product;
TPC: the power control commands word at descending HS-PDSCH channel, use 2 bits;
ACK: originally be carried on the response feedback on the HS-SICH, and used 1 bit at the last transmission block that carries of HS-PDSCH.
Wherein, the identification information of the transmission block size of 2 bits, the hybrid automatic repeat request process of 0 bit number, the transmission first of 1 bit or the identification information that retransmits are used for the control information at E-PUCH, and the correct identification message of replying of whether transmitting of 1 bit is used for going up data control information at HS-PDSCH.
As seen, in the embodiment of the invention, 10 bits that control information in the prior art is required are improved to 6 bits, have saved the resource overhead in control information greatly.Further, in E-UCCH feeding back ACK/NACK, also feed back power control command word TPC, make network equipment to adjust the transmitting power of HS-PDSCH according to the order of the TPC on the E-UCCH that receives at HS-PDSCH.What propose especially is, be not limited in by control information for TPC and feed back to network equipment, owing to its role is to HS-PDSCH be carried out the foundation of power control as network equipment, therefore, as long as subscriber equipment can feed back to the purpose that network equipment just can realize HS-PDSCH is carried out power control.

Lifting an example below again is described further enforcement of the present invention.
Fig. 7 is the data transmission service implementing procedure schematic diagram of network equipment and subscriber equipment, as shown in the figure, comprises the steps:
Step 701, radio bearer set up or physical channel is reshuffled, and turn to step 702 and 706.
In this step, set up or physical channel when reshuffling at radio bearer, high-rise by the basic data block size of RRC signaling UE, monitoring HS-SCCH and transmit the physical resource that HS-PDSCH takies first.
Step 702, UE monitor continuously to the HS-PDSCH code channel that high level distributes, and adopt the master data block size of high-rise notice that data are carried out blind decoding.
If step 703 is decoded correctly then is forwarded step 704 to, otherwise forwards step 705 to.
Step 704, UE feeding back ACK, this message is included among the E-UCCH, is carried on the E-PUCH channel, changes step 712 over to.
Step 705, UE save the data in the buffer memory, change step 712 over to.
Step 706, the high-rise HS-SCCH channel that distributes of UE real-time listening.
This step both can not carried out simultaneously with step 702, also can carry out simultaneously, there is not inevitable sequential relationship between the two, because the channel of being monitored in two steps is different, subscriber equipment is monitored the HS-PDSCH channel so that obtain first control signaling in the step 702, and this step monitors that the HS-SCCH channel obtains is the control signaling of retransmitting, so this step can not carried out with step 702 while simultaneously yet.
Step 707, judge whether the control of this UE signaling is arranged on the HS-SCCH,, otherwise forward step 706 to if having then forward step 708 to.
Step 708, the data retransmission on the HS-PDSCH is received and decodes.
The physical resource that HS-PDSCH took when UE went up the re-transmission of indicating according to HS-SCCH is decoded to the HS-PDSCH code channel on these physical resources.
Step 709, judge whether decoding is correct,, otherwise forward step 711 to if decoding correctly then forward step 710 to.
Step 710, UE feeding back ACK, this message is included among the E-UCCH, is carried on the E-PUCH channel, changes step 712 over to.
Data after step 711, UE will merge are kept in the buffer memory, and feedback NACK, and this message is included among the E-UCCH, is carried on the E-PUCH channel, changes step 712 over to.
Step 712, network equipment are received the ACK message of UE feedback, and this end of transmission is received then retransmission data of NACK.
Wherein, the Initial Trans of HS-PDSCH channel is determined by network equipment, the control of following adopted closed power.UE is after executing above-mentioned step 704, step 710, step 711, feedback is at the power control command word TPC of HS-PDSCH in E-UCCH feeding back ACK/NACK, and network equipment can be adjusted the transmitting power of HS-PDSCH according to the order of the TPC on the E-UCCH that receives.
By above-mentioned enforcement as can be seen, the ACK/NACK feedback that among the present invention prior art is carried on the HS-SICH is placed on upward carrying of E-UCCH, has therefore saved the resource on the HS-SICH.
Further, transmission first takies different physical resources with re-transmission.The physical resource that takies of transmission is determined by high level and is set up or physical channel notice when reshuffling at radio bearer first, the physical resource that takies during re-transmission by network equipment before re-transmission in the HS-SCCH notice, thereby saved the resource overhead of HS-SCCH; Notify physical resource by HS-SCCH during re-transmission, make to retransmit to take different physical resources, increased the flexibility of resource allocation with transmission first.
At last, also the HS-PDSCH channel has been adopted closed power control.Prior art is not done power control to this channel, but utilizes the AMC technology, when promptly power is big, adopts bigger TBS and modulation system, makes full use of the power delivery more data.Yet what the present invention is directed to is the comparatively fixing business of code check, and for this situation, the AMC technology does not adopt substantially, therefore need carry out power control to this channel.After the present invention receives HS-PDSCH by UE, form a TPC order and on up channel, feed back, require network equipment to carry out corresponding power adjustment.Therefore solved power control problem to the HS-PDSCH channel.
Obviously, those skilled in the art can carry out various changes and modification to the present invention and not break away from the spirit and scope of the present invention.Like this, if of the present invention these are revised and modification belongs within the scope of claim of the present invention and equivalent technologies thereof, then the present invention also is intended to comprise these changes and modification interior.
