This data mask is then further processed as the CRC field and transmitted with the data burst to provide CRC-related functions. An alternative embodiment discloses initializing a CRC generator with UE identification prior to CRC generation. This implicitly includes the UE ID within the CRC without requiring additional overhead signaling.
Description
The application is to be that November 14, application number in 2003 are dividing an application of 02809881.1 application for a patent for invention the applying date.
Technical field
The present invention is about wireless communication field.A kind of application of the present invention is down link (downlink) signaling method of CRC (cyclic redundancy check) that is used for the modification of data protection and the single/UE of group sign about use.
Background technology
Wireless communication system has become the link that must have in modern communications capital construction today.With this and opinion, it not only relies on the support of voice communication day by day, and also relies on the support of data communication.Voice communication has relatively low speed, and in up and downlink bandwidth, is symmetrical, and can be by the amount of bandwidth of forecasting institute need.
Yet data communication possibly cause difficult tired burden in telecommunication system, especially in radio telecommunications system.At first, data communication needs high data rate usually.Secondly, the required amount of bandwidth of application associated with the data can change significantly, from thousands of conspicuous to the number megahertz.The 3rd, the amount of bandwidth in up and down direction has different completely.For example, with typical internet browser application, the data of minute quantity are sent in uplink direction, but have the data of huge amount to be downloaded at down direction.These factors possibly cause great constraint to radio telecommunications system.
Wideband CDMA (WCDMA) standard; Like leading Global 3G 3G) (IMT-2000) standard; In indoor/sub-district outdoor environment, support to contain the data rate of supporting in (switch wide-area coverage) up to 384Kb/s, and support High Rate Packet Data and two-forty circuit switched data up to the data rate of 2Mb/s with in the exchange extensive region.Yet,, need substantial increase be arranged in this data rate, particularly at down link for satisfying the further requirement of packet data service.High-speed downlink packet inserts (HSDPA) and will allow down link peak data rate that WCDMA supports about 8-10Mb/s to obtain the packet data service of optimum efficiency.This speed is far above the 2Mb/s demand of IMT-2000.At the capacity of also having strengthened grouped data aspect the low capacity that postpones and improve.
Support that a kind of method of data communication is to each subscriber equipment (UE) assigned with dedicated channel.Yet this causes the inefficiency to heavens that bandwidth is used, and is quite long-standing idle because this kind channel is kept usually.
The another kind of method that replacement is used for the dedicated channel of each UE is the use of high speed shared data channel and packet.A plurality of high speed data channels are shared between a plurality of UE in the method.These UE with the data that are used for transmitting or receive are dynamically allocated of shared data channel.This causes the use of more efficient frequency spectrum.
Figure 1A-Fig. 1 C representes a kind ofly have the flow process of assigning high speed shared data channel when waiting for the data be transferred to particular UE when the base station.With reference to Figure 1A, relevant downlink dedicated physical channels (DPCH) is transferred to each UE.Relevant down link DPCH and the shared control channel (SCCH-HS) of this UE monitoring.When data from base station transmits to UE not, UE gets into standby mode, and " revive " from then on periodically (wake up) is to attempt to monitor its relevant down link DPCH and SCCH-HS.This allows this UE to save flow process and battery supply.
If the data in the base station have been ready to be transferred to UE, high-speed downlink shared channel (HS-DSCH) designator (HI) is transmitted in relevant DPCH.HI has the N bit length, 2 shown in its indication Figure 1B
nAmong the individual SCCH-HS one.For example, 2 HI can indicate 4 SCCH-HS, and promptly 00,01,10 or 11.
The example shown in Figure 1A for example, when the 3rd channel among indication Figure 1B, HI is (1,0).When UE access during by the control channel of HI sign, specific SCCH-HS will guide extremely suitable HS-DSCH of this UE, and it has been configured the UE that gives these reception data.Shown in Fig. 1 C, for example, UE is adjusted to the HS-DSCH (001) by SCCH-HS (1,0) sign.This UE is received as it and the data of sending subsequently on HS-DSCH (001).It should be noted that the icon of Figure 1A-Fig. 1 C has been represented the explanation of the flow process of assigning HS-DSCH, and the structure of channel and use maybe be slightly different with the actual design in the HSDPA standard.
As the efficient method of the assignment common data channels that transfer of data is used is provided with reference to the flow process shown in Figure 1A-Fig. 1 C.Transmit because grouped data is expected to be one or more particular UE, UE sign (ID) is the important parameter from base station transmit signals to UE.
There are a lot of prior aries to be used between base station and UE, sending the method for UE ID.With reference to Fig. 2 A, first method appends to UE ID the data that are used to transmit.Such combination is fed to the Cyclic Redundancy Check generator, and it exports CRC.The packet that is produced that transmits at last comprises X bit data field, M position UE ID and N position CRC, shown in Fig. 2 B.Though this provides the two enough signals of CRC and UE ID to send, it sends bandwidth to signal and wastes.
Another prior art that is shown in Fig. 3 A is attached to UE ID on the data field that is input in the CRC generator.CRC generator output CRC.Shown in Fig. 3 B, the data pulse string of this transmission usefulness comprises X bit data field and N position crc field.Though this also enough sends UE ID and CRC between base station and the UE, this method is undesirable, uses because it possibly be merely single UE sign.When one group of UE need be identified, the method also caused the complexity of UE.
Summary of the invention
The present invention discloses some and is used for the implementation method that the relevant down link signal of data sends.These execution modes disclose adjusts UE ID selectively to produce UE ID value, and it is added to data field to produce data mask by mould 2 subsequently.This data mask subsequently can be by further processing as crc field.Crc field is transmitted so that CRC to be provided relevant function with data pulse string (burst) then together.Another replacement execution mode discloses and before CRC produces, has utilized UE sign initialization CRC generator.Comprise UE ID among this CRC of lying in, and do not needed extra signaling consumption.
The invention provides a kind of being used for is sent to the method for Unit second with a data pulse string from first module, and this method comprises: in this first module: receive the data that are used to send; The sign of filling this Unit second is to produce fill field, and the length of this fill field equals the length of these data; Mould 2 adds that these data and this fill field are to form shielding; Produce first CRC based on this shielding; This first CRC is appended to these data to form data pulse string: and send this data pulse string; In this Unit second: receive this data pulse string; Calculate second CRC based on the data pulse string that is received; Mould 2 adds to this second CRC with this first CRC, sends sign thereby produce; Relatively the sign of this Unit second and said transmission identify; If this transmission sign conforms to the sign of this Unit second, declare that then this first CRC is correct; If this transmission sign is not inconsistent with the sign of this Unit second, declare that then this first CRC is incorrect.

With reference to Fig. 5 B, the crc field 212 of generation is added to data field 202 and is used for transmission.
Use second execution mode of the present invention of implicit expression UE ID to present simplification, and stable, because of it need and not disassembled with the combination of SCCH-HS and UE ID,, required like the specific CRC method of the UE of the prior art and first execution mode at transmitter and receiver.
With reference to Fig. 6 A, show the 3rd execution mode of the present invention.In this embodiment, system 300 use from the data of data field 302, from UE id field 308A UE ID, modulo 2 adder 310 and shield 311, CRC generator 304 and the crc field 312 that produced.System 300 receives data field 302 and will be input to first input of modulo 2 adder 310 from the data of data field 302.Therefore, from the data of data field 302 with from the UE ID of UE id field 308A by exclusive-OR to produce shielding 311.Shielding 311 is imported in the CRC generator 304 that generates crc field 312.
In this embodiment, the figure place of UE id field 308A (M position) must be identical with the figure place (X position) of data field 302 so that carry out nodulo-2 addition.If M equates with X, can directly add to data from data field 302 with mould 2 from the value of UE id field 308A.Yet,, need intermediate steps that it is equated if M and X are unequal.If M is less than X, then UE ID is filled X-M mantissa 0, and therefore the value from UE id field 308A equals data field 302 on length." the UE ID value that is filled " shown in Fig. 6 A added to the data from data field 302 by mould 2 subsequently.
Because the length X of data field 302 does not hope that M will be greater than X.Yet,, clipped in the value of minimum effective M-X position from UE id field 308A if this situation takes place.This UE ID by brachymemma is added to the data from data field 302 by mould 2 subsequently.
With reference to Fig. 6 B, the county shows the 4th execution mode of the present invention.In this embodiment, the function mode of system 301 is identical with the 3rd execution mode of Fig. 6 A.Difference at this execution mode only is the production method from the value of UE id field 308B.Therefore in this embodiment, UE ID is filled X-M front 0, and the length from the UE ID of UE id field 308B equals data field 302.This " the UE ID value that is filled " shown in Fig. 6 B, added to the data from data field 302 by mould 2 subsequently.It should be noted that this filling can comprise the combination (not shown) of front and afterbody 0 selectively, so that UE ID length is equated with data field.
With reference to Fig. 6 C, the crc field 312 that is generated from the system 300 of the execution mode shown in Fig. 6 A, or be affixed to the data field 302 of transmission usefulness by the CRC 314 that the system 301 of the execution mode shown in Fig. 6 B is generated.Therefore, crc field 312 or 314 can be used and be additional to data field 302.
With reference to Fig. 7 A, show fifth embodiment of the invention.In this embodiment, system 400 use from the data of data field 402, from UE id field 408A UE ID, modulo 2 adder 410 and shield 411, CRC generator 404 and the crc field 412 that produced.System 400 receives data field 402 and will be input to first input of modulo 2 adder 410 from the data of data field 402.Exported to second input of modulo 2 adder 410 from the UE ID of UE id field 408A.From the data of data field 402 and from the UE ID of UE id field 408A by exclusive-OR so that produce shielding 411.This shielding 411 is imported into CRC generator 404, and it produces crc field 412.
In this embodiment, the figure place of UE id field 408A (M position) must be identical with the figure place of data field 402 so that carry out nodulo-2 addition.If M equates with X, will be added to data by direct mould 2 from data field 402 from the UE ID of UE id field 408A.Because the length of data field 402 does not hope that M will be greater than X.Yet if this situation takes place, least significant bit is clipped till the length of UE ID equals X from UE id field 408A.This UE ID by brachymemma adds to the value from data field 402 with mould 2 subsequently.
If the length of UE ID is less than data field 402, then " compound UE ID " produced, and therefore the value from UE id field 408 equals X.Compound UE ID is produced up to suitable X bit field through repetition UE ID many times, subsequently to be inserted remaining tail bit by the UE ID of brachymemma.This is indicated among the UE id field 408A of Fig. 7 A.This compound UE ID is added to the data from data field 402 with mould 2 subsequently.
With reference to Fig. 7 B, show the 6th execution mode of the present invention.The function mode of the system 401 of this execution mode is identical with the 5th execution mode of Fig. 7 A.The difference of this execution mode only is the value from UEID field 408B.Though compound UE ID is produced with the mode with Fig. 7 A, partly be coupled with as the front by the UE ID of brachymemma, opposite with tail bit among the UE id field 408A shown in Fig. 7 A.It should be noted, can be comprised combination anterior and afterbody brachymemma position by the UE ID " filling " of brachymemma, so that the length of UE ID is identical with data field 402.
With reference to Fig. 7 C, the crc field 412 that produces from the system 400 of the 5th execution mode of Fig. 7 A or be affixed to data field 402 from the crc field 414 that the system 401 of the 6th execution mode of Fig. 7 B produces and be used for transmission.Therefore, the type of one of crc field 412,414 will be used and append on the data field 402.
It should be noted that all above-mentioned execution modes can be used to support multiple sign (ID).UE maybe be with different stage processing messages address: 1) the single ID of UE, 2) ID of corresponding subclass or one group of UE, wherein UE belongs to this subclass; Or 3) broadcasting of all UE in the corresponding system (all ID).For example, as shown in Figure 8, UE ID 12 can be received and handle ID:1 by high bright sign at 4 different stages to indicate it) UE-specific ID (#12); 2) secondary subset C ID; 3) subclass 2ID; And 4) all ID.Therefore on the same group UE it should be noted that the group identification A-E that replaces also can be produced, in can not be comprised in.For example, group B will comprise that all are expressed the UE near crowd B, and it comprises UE numbers 2,7,12,17,22 and 27.Therefore, any group or child group can be produced through specifically discerning indivedual UE, such as the user hope.
For supporting this demand, the said CRC that generates of transmitter such as each execution mode.At receiver, UE handles this message and produces the CRC of expection, need not be the modification on basis with ID.The UE processor adds to the CRC that is calculated with the CRC mould 2 that is received subsequently.The ID that is output as transmission that produces, it can be any above-mentioned ID.If this ID is not person one of among these ID, then this UE abandons transmission.According to the present invention, use the CRC sign indicating number of length N, the not detection error possibility on the SCCH-HS of sign is near 2
-nThe data of using 24 CRC on HS-DSCH, to transmit with protection, the control information of using 16 CRC on SCCH-HS, to transmit with protection, and suppose that the false acceptance rate of the HI position of non-predetermined UE is 10

This reliability is calculated and is pointed out, as far as the CRC of equal length, the possibility that the user transmits misdata to higher level will extremely reduce.
With reference to Fig. 9, this flowchart text is handled the method for the downlinlc message between Node-B and the UE according to the present invention.This method provides roughly general introduction should not be interpreted as the description of the understanding of the required physical layer signaling (being packet) of all detailed medium access controls (MAC) layers and processing messages.Node-B at first produces down link control messages in the MAC layer, and (step 1) is forwarded to physical layer (step 2) with this message and UE ID subsequently.This physical layer produces CRC and uses UE ID, and (step 3) is a data pulse string to transmit with said message.This message is transferred into UE (step 4) from Node-B subsequently.In this physical layer, UE ID and CRC by verification to confirm their whether correct (step 5).If message is forwarded to the MAC layer, and (step 6), MAC layer are further handled this message (step 7) subsequently.
It should be noted that the step 6 of Fig. 9 comprises the extra between physical layer and the MAC layer, it comprises the effective control messages of indication CRC/UE ID.Yet this is an optional step.In a preferred embodiment, have only effective message to be forwarded to the MAC layer from physical layer.Therefore, in a preferred embodiment, the MAC layer will suppose that the message of any MAC of being forwarded to is for effective.In the execution mode of another replacement, extra CRC/UE ID useful signal will be treated as additional acknowledgement with this forwards.
The present invention has and has eliminated the UE ID that separates and the treatment step of CRC.When two fields as previously mentioned as by being combined, this UE will further handle any message, till CRC and UE ID the two (or ID of other type shown in Figure 8) are all correctly.
Though the present invention is described according to preferred implementation, other modification of liking enclosed in the scope of the present invention that claim indicates will be apparent to those skilled in the art.
