Background technology
Along with the development of 3G technology, in order to adapt to the multimedia service needs growing, 3G (Third Generation) Moblie collaborative project group (3GPP, 3 to high speed data transfer
RdGeneration Partnership Project) announced high speed downlink packet access (HSDPA, High Speed Downlink Packet Access) technology.The HSDPA technology is a kind of enhanced scheme that 3GPP Release 5 proposes, utilize Adaptive Modulation and Coding (AMC, Adaptive Modulation and Coding) technology, mix automatic repeat requests (HARQ, Hybrid Auto Repeat Request) technology etc. realizes the performances such as high-throughput, little delay and peak data rates of downstream data traffic, has strengthened the function of downlink transmission greatly.
In the prior art, the HARQ technology has and mainly is divided into following three classes, and first kind HARQ, the second class HARQ, the 3rd class HARQ are in the mechanism in the middle of two classes in addition.
First kind HARQ, receiving terminal is decoded to the packet that sends first, if can not be correctly decoded, the feedback information request retransmission abandons error data packets simultaneously, retransmits the fixing packet that sends same-code, and does not do any merging at receiving terminal;
The second class HARQ is full incremental redundancy (IR, Incremental Redundancy) retransmission mechanism, the error data packets that receives can not be dropped, but decode again afterwards with the redundant information merging that retransmits, new redundant information merges with the information transmitted of before having received first, forms stronger error correcting code, because retransmission information only comprises new redundant information, and the mode of multiple coding punching is arranged, some kinds of redundant information versions are arranged usually;
The 3rd class HARQ is partial redundance HARQ, similar to the second class HARQ, the misdata Bao Buhui that receives is dropped, store and decode after merging with follow-up data retransmission but be received end, the data that retransmit comprise that not only redundant information also comprises systematic bits, thereby data retransmission information can self-demarking code, includes different punching bits in the data packets for transmission during re-transmission.
The HSDPA technology comprises 2 down channels: High-Speed Shared Control Channel (HS-SCCH, High-speedShared Control Channel) and high-speed physical downlink shared channel (HS-PDSCH) (HS-PDSCH, High-speedPhysical Downlink Shared Channel).Wherein, the HS-PDSCH channel is used for the business datum of bearing downlink, and the HS-SCCH channel is used to carry the control information relevant with the HS-PDSCH business datum.
Existing 1.28M time division duplex (TDD, Time Division Duplex) the HS-SCCH channel occupancy of pattern is that two spreading factors are the code channel of 16 (being SF16), comprise the control information of uplink synchronous control word SS and uplink power control control word TPC on one of them code channel, wherein, above-mentioned SS and TPC are used for carrying out synchronously and power control with the corresponding high-speed shared information channel of this HS-SCCH channel (HS-SICH, HighSpeed-Shared Information Channel).The control information of transmitting in the HS-SCCH channel mainly comprises transport format resource indication (TFRI, Transport Format ResourceIndicator), HARQ (asynchronous HARQ) information, user ID (UE-ID, User Equipment ID), relevant information such as uplink power control control word, following table 1 is the detailed description of the control information transmitted in the HS-SCCH channel:
Table 1
When the HS-SCCH control information is encoded in the his-and-hers watches 1, with terminal user identification information (UE-ID) and cyclic redundancy check (CRC) (CRC, Cyclical Redundancy Check) check code is formed 16 bit code, and then and 20 bits of TFRI information and 10 bits of HARQ information be linked to be 46 bits together in order, and then after adding 8 tail bits, 1/3 convolutional encoding according to the R99 version, promptly (46+8) * 3 obtain 162 bits, obtain 172 bits through after the rate-matched again, wherein 88 bits use a code channel carrying, and other 84 bits add that SS and TPC are by other code channel carrying.
Transmission mechanism according to existing HSDPA, all need to user terminal (UE in the transmission first of carrying out data at every turn and before retransmitting, User Equipment) control information of the HS-SCCH of two code channels of transmission, be notified to corresponding user terminal, and then the relevant business datum (send first or retransmit) of transmission, that is to say, terminal receives the data of HS-PDSCH and must finish under the cooperation of HS-SCCH control information, this transmission mechanism is for the business datum of small data packets IP telephone service (VoIP for example, Voice over IP) etc., because itself required control information is fewer, if still can transmit a large amount of control informations according to existing HSDPA mechanism, then can cause waste, also reduce the efficient of transmission simultaneously the HS-SCCH channel resource.

Embodiment
Below in conjunction with accompanying drawing, elaborate the transmission method of business datum provided by the invention in HSDPA with specific embodiment.
Because the redundant information that when retransmitting may be this business datum of re-transmission also may be to retransmit redundant information and systematic bits information, clearly describe hereinafter unified be called " business datum of re-transmission " for simpler.And NodeB is called " business datum of Chuan Songing first " to the new data (business datum of non-re-transmission) that UE sends at every turn.
In the embodiment of the invention, existing transmission mechanism is improved, adopt synchronous hybrid automatic repeat request mode, fixing QPSK modulation system, preestablish incremental redundancy version number; Physical resource (time-slot code channel information) is by Radio Resource control (RRC, Radio Resource Control) layer signaling; The base station sends to UE and includes only the control information that comprises High-Speed Shared Control Channel cyclic sequence number, transport block size index and user ID; Because the transmission of control information can have multiple mode in the practical application, the present invention does not do qualification to the base station to the send mode of the control information of UE transmission, and for convenience of description, the base station sends above-mentioned control information by HS-SCCH in the embodiment of the invention.Base station (NodeB) only sends this control information before the user terminal service data transmission first, if the business information that UE reception NodeB transmits first can not be correctly decoded, the information of feedback NACK, NodeB no longer sends this control information before again when business datum that UE send to retransmit.
The control information that the base station sends to UE in the embodiment of the invention, the control information with respect to HS-SCCH carrying of the prior art has significantly reduced amount of information.NodeB is on 16 the code channel to being carried on spreading factor of HS-SCCH behind the control information coding that UE sends in the embodiment of the invention.Following table 2 is contrasts that the amount of information of the control information that HS-SCCH carries in control information that UE sends and prior art of base station in the embodiment of the invention is carried out.
Table 2

Below the related content in the last table 2 is carried out detailed explanation:
Owing to just before UE sends the business datum of transmission first, just send above-mentioned HS-SCCH control information at NodeB, before retransmitting, NodeB no longer sends this control information, so the business datum that this control information corresponding UE receives is fixed as new data, rather than the business datum that retransmits; Needn't comprise the information of new data indication in this control information, this content bits number is 0 in this control information;
Because the code channel of HS-SCCH indication is identical in each time slot, and when time-slot code channel information is set up in the Radio Resource control connection, give UE by the RRC signaling that radio resource control layer is assigned, use HS-SCCH to pass on this information so no longer include, so the shared bit number of time-slot code channel information is 0;
Incremental redundancy version number adopts predefined mode to be associated with the number of times of transmission, promptly corresponding different transmission (re-transmissions) number of times predefine adopts different incremental redundancy version number separately, so base station incremental redundancy version number shared bit number in the control information of UE transmission is 0 in the embodiment of the invention;
The embodiment of the invention adopts synchronous HARQ mechanism, promptly only retransmits in the time of appointment, and therefore the process ID that does not need to indicate HARQ is 0 so the process of HARQ is discerned shared bit number;
Because rrc layer is four kinds of available transmission block (TBS of each UE configuration, Transport block set) (the transmission block size of each UE configuration has kind more than 60 to size in the prior art, therefore its index value is 6 bits), transmission block is indicated the index value of the corresponding transmission block size of this transmission (transmit first and retransmit) in the table 2, is 2 bits;
The fixing modulation system that adopts four phase shifts to keying (QPSK, Quaternary Phase Shift Keying) of the embodiment of the invention is so the bit number of modulation system is 0.
Hold at UE, after UE receives this control information, distribution time-slot code channel information according to the radio resource control layer signaling, receive the business datum of descending HS-PDSCH, and according to size information, the UE identification information of HCSN information, transmission block in the HS-SCCH control information, and other control informations of notifying by agreement and high-level signaling such as modulation system, incremental redundancy version number descending business datum that the NodeB that receives is transmitted first and the data of re-transmission are carried out the demodulation sign indicating number.
At NodeB during at every turn to business datum that UE send to retransmit, because what retransmit employing is synchronous HARQ, UE judges the number of transmissions of current re-transmission by the current time, know the version number of the incremental redundancy information that receives then by the number of transmissions, the data retransmission of different the number of transmissions correspondences is merged with decoding wrong data before, and the data after being combined according to transport block size information are again decoded.
In the embodiment of the invention, NodeB sent this control information send the business datum that transmits first each time to UE before, if UE can not carry out correct decoding with the business datum that transmits first that receives, when needing to retransmit this business datum, NodeB before UE sends the business datum that retransmits, no longer sends any control information each time.
Because the mode difference that retransmits, NodeB is two kinds of patterns below the whole flow process of UE transmission data is divided into, and it describes respectively below in conjunction with accompanying drawing.
The mode that retransmits in first kind of flow process adopts the fixing mode that retransmits, and fixedly number of retransmissions is N time.When the RRC connection was set up, N was by the high-rise configuration of RRC and be notified to UE, and NodeB is when retransmitting, and UE does not feed back and is correctly decoded acknowledge message (ACK) or decoded in error acknowledge message (NACK).Its transfer process as shown in Figure 1, concrete transfer process comprises following step:
The initial value of step 101, setting control information the number of transmissions 1 is 0 time;
Following abnormal conditions may appear in the transmission of actual traffic data: if UE fails to receive this control information, then can on the corresponding physical channel, not receive descending business datum, so also just can not be on HS-SICH the information of feeding back ACK or NACK, for fear of the situation that UE fails to receive this control information occurring, after step 103, increased step 104 to step 106;
If if NodeB does not receive any feedback information of UE in the time of setting, then NodeB judges that UE does not receive this control information, carries out determining step 106; If NodeB judges ACK or the NACK message of having received the UE feedback in time of setting, then execution in step 107;
The business datum that transmits first that step 107, UE will receive is decoded, and can judgement be correctly decoded; If can be correctly decoded, turn to step 108; If the business datum that transmits first that UE receives can not be correctly decoded, then turn to step 109;
When UE fix N time sent the business datum that retransmits, UE carried out demodulation to the business datum of the re-transmission that NodeB sends each time at NodeB, merged decoding with the business datum of the decoding error of storage.If number of retransmissions is not when reaching N time, UE is correctly decoded after the business datum merging with the decoding error of the business datum that retransmits and storage, and then UE no longer decodes to the business datum of the re-transmission of follow-up reception or it is abandoned.
Fig. 2 is a Signalling exchange schematic diagram between the NodeB of corresponding above-mentioned first kind of transmission mode and UE.
