Embodiment
In order to make the object of the invention, technical scheme and advantage clearer, describe the present invention below in conjunction with accompanying drawing and specific embodiment.
Method provided by the invention mainly comprises: the HS-SCCH signaling that the following equal length that adopts of each functional requirement condition is set; According to the corresponding relation between channelization code information and the functional requirement in the preset HS-SCCH signaling, confirm the pairing channelization code information of current functional requirement, and send the HS-SCCH signaling that comprises this channelization code information; Wherein, said functional requirement comprises MIMO function or CPC function.
In addition; When current functional requirement is the MIMO function; Can also confirm the pairing channelization code information of current resource type further according to the corresponding relation between channelization code information and the resource type, the channelization code information that comprises in the HS-SCCH signaling of above-mentioned transmission is the channelization code information that had not only satisfied current functional requirement but also satisfied current resource type; Wherein, the resource type under the MIMO function is MIMO single-stream transmission resource or MIMO stream transmission resource.Perhaps, further when current resource type was MIMO single-stream transmission resource, it is invalid that the TBS territory of one of them data flow is set to, and when current resource type is MIMO stream transmission resource, the TBS territory of two data flow all is set to effectively.
When current functional requirement is the CPC function; Can also be further according to the corresponding relation between resource allocation cycle information and the resource type; Confirm the pairing resource allocation cycle information of current resource type; Also comprise the resource allocation cycle information that this is confirmed in the HS-SCCH signaling of above-mentioned transmission, wherein, the resource type under the CPC function is semi-continuous resource allocation type or temporary scheduling resource type.
Below in conjunction with specific embodiment said method is described in detail.Method provided by the invention can mainly be divided into following two kinds of situation according to the length of HS-SCCH signaling:
First kind of situation: all adopt under each functional requirement condition and the isometric signaling structure of traditional HS-SCCH signaling, i.e. 46 bits.
Because the single-stream transmission of MIMO needs 16 HARQ processes; And the HAP territory of sign HARQ process number is merely 3 bits in traditional HS-SCCH signaling structure; Can only represent 8 HARQ processes at most, therefore, traditional HS-SCCH signaling HS-SCCH can not be used for the transmission of MIMO single current; At this; The present invention is new to be proposed a kind of 46 bit lengths and is used to carry the HS-SCCH signaling structure of MIMO single-stream transmission resource control information, and the HAP territory takies 4 bits in this structure, removes the NDI territory that takies 1 bit originally and/or the RV territory that will take 3 bits originally is adjusted into 2 bits.For example, can adopt HS-SCCH signaling structure shown in Figure 2, in structure shown in Figure 2; The HAP territory takies 4 bits, can support 16 HARQ processes, owing to do not comprise the NDI territory; Therefore, can be in the RV territory explicitly indication redundancy versions no longer, but define the corresponding relation between redundancy versions and the RV value in advance; One of them RV value is used for fixing the expression new data transmission, and other represent to retransmit; Other each territories can be identical with the structure in traditional HS-SCCH signaling.This structure can also be used for the scheduling use that the data on the non-semi-continuous resource of CPC just pass or retransmit.In this structure, channelization code information is the value of initial code when being less than or equal to the value of stop code, shows that spreading factor (SF) is 16, initial code get 15 and stop code got 0 o'clock, show that SF is 1.
Existed a kind of HS-SCCH signaling structure of 46 bit lengths to be used to carry MIMO stream transmission resource control information in the prior art, the present invention can directly adopt this HS-SCCH signaling structure.The HS-SCCH signaling structure that is used to carry MIMO stream transmission resource control information under 46 bit lengths of Fig. 3 for embodiment of the invention employing; As shown in Figure 3, this structure is compared with traditional HS-SCCH signaling, comprises the RV territory of two data flow; Respectively account for 2 bits, do not comprise NDI information.Content in its channelization code information and traditional HS-SCCH signaling are inequality; Second data flow of the second data stream modulates information (Mod2) and 5 bits of MIMO identification information, 1 bit that wherein comprises 2 bits is with respect to the TBS size offset information of first data flow, and the structure of channelization code information is as shown in Figure 4.Wherein, the 1st bit and the 5th bit are the MIMO identification information, get fixed value and are used to identify this HS-SCCH and are used for the MIMO stream transmission.That is to say,, confirm that then this HS-SCCH is used to carry MIMO stream transmission resource control information, wherein the desirable arbitrary value of x if channelization code information is 1xxx0xxx.When but the HS-SCCH of this structure is used to carry MIMIO stream transmission resource control information, only support that SF is 1.
Existed a kind of HS-SCCH signaling structure of 46 bit lengths to be used for semi-continuous resource allocation type or temporary scheduling resource type under the CPC function in the prior art; But it only can be distinguished with traditional HS-SCCH signaling; And can not distinguish with the HS-SCCH signaling under the MIMO function provided by the invention; Therefore, the present invention is provided for the HS-SCCH signaling structure and the HS-SCCH signaling structure that is used for temporary scheduling resource type under the CPC function of the semi-continuous resource allocation type under the CPC function respectively at this.
The HS-SCCH signaling structure that is used for the semi-continuous resource allocation type of CPC function under 46 bit lengths that Fig. 5 provides for the embodiment of the invention; Can comprise the channelization code information of 12 bits, the TS of 5 bits, the Mod of 1 bit, the HCSN of 3 bits in the HS-SCCH signaling of this structure; TBS, CRC and the UE ID of the semi-continuous resource entry-into-force time of 5 bits, the HS-SICH of 2 bits indication, 2 bits, the semi-continuous resource of semi-continuous resource entry-into-force time indication base station assigns wherein from which TTI comes into effect; HS-SICH indication is used for representing the employed HS-SICH of feedback information after UE is for the data decode that receives on the semi-continuous resource.Wherein, channelization code information is improved with respect to structure of the prior art, comprises the CPC sign of 4 bits, the resource allocation cycle of 2 bits and the code channel information (CCS) of 6 bits; As shown in Figure 6; The 1st, 2,5 and 6 bits of channelization code information are CPC sign, get fixed value and identify and be used for the CPC function, identify this HS-SCCH when promptly channelization code information is for 11xx10xxxxxx and are used for the CPC function; Wherein, the desirable arbitrary value of x; The code channel information that wherein CCS indication distributes, minimum particle size is that 2 SF are 16 code channel, can use that preceding 3 bits can be used as initial code in the CCS territory, back 3 bits are as stop code, and initial code be 7 with stop code be that 0 to identify SF be 1.
Be used for the HS-SCCH signaling structure of the temporary scheduling resource type of CPC function under 46 bit lengths that Fig. 7 provides for the embodiment of the invention, can comprise the channelization code information of 12 bits, the TS of 5 bits, the Mod of 1 bit, the HCSN of 3 bits, the TBS of 2 bits, the RV of 2 bits, the PTR of 4 bits in the HS-SCCH signaling of this structure; Wherein, PTR is used to represent that this retransmits the TTI number with the last transmission intercal of this packet.Wherein, identical among the form of channelization code information and Fig. 5, promptly the 1st of channelization code information the, 2,5 and 6 bits are the CPC sign; Getting fixed value identifies and is used for the CPC function; Be that channelization code information identifies this HS-SCCH during for 11xx10xxxxxx and is used for the CPC function, wherein, the desirable arbitrary value of x; The code channel information that CCS indication wherein distributes, minimum particle size is that 2 SF are 16 code channel.
To the CPC function, can utilize the resource allocation cycle information in the channelization code information to confirm that this HS-SCCH signaling is used for semi-continuous resource allocation type or temporary scheduling resource type.For example, can with 00 represent only to distribute a TTI physical resource, promptly identify this HS-SCCH signaling and be used for the temporary scheduling resource type; Use 01 expression to distribute 20ms to be the semi-persistent physical resource in cycle, uses 10 expressions to distribute 80ms to be the semi-persistent physical resource in cycle, 11 expression distribution 160ms are the semi-persistent physical resource in cycle, represent that promptly this HS-SCCH signaling is used for semi-continuous resource allocation type.
Under this first kind of situation; When promptly adopting the HS-SCCH signaling of 46 bits, when the base station confirms that current functional requirement is the MIMO function, send the pairing HS-SCCH signaling structure of MIMO function; Channelization code information in this HS-SCCH signaling is the pairing channelization code information of MIMO function; Be specially: to the control information transmission of MIMO single current, the initial code value in the channelization code information is less than or equal to the stop code value, perhaps the initial code value be 15 and the stop code value be 0; To the control information transmission of MIMO double fluid, the 1st bit in the channelization code information is got 1, the 5 bit and is got 0.When the base station confirms that current functional requirement is the CPC function; Send the pairing HS-SCCH signaling structure of CPC function; Channelization code information in this HS-SCCH signaling is the pairing channelization code information of CPC function, is specially: the 1st, 2,5 and 6 bits of channelization code information get 1,1,1 and 0 respectively; And in channelization code information, carry with current resource type to corresponding resource allocation cycle information.
Correspondingly; After UE receives HS-SCCH; Obtain the channelization code information among this HS-SCCH; According to the corresponding relation between channelization code information and the functional requirement in the preset HS-SCCH signaling, confirm that this HS-SCCH signaling is used for MIMO function or CPC function, if confirm to be used for the MIMO function; Then further according to the corresponding relation between channelization code information and the resource type; What confirm this HS-SCCH signaling bear is MIMO single-stream transmission resource control information or MIMO stream transmission resource control information, is specially: if the initial code value in the channelization code information is less than or equal to the stop code value, perhaps the initial code value be 15 and the stop code value be 0; What then confirm this HS-SCCH signaling bear is MIMO single-stream transmission resource control information, according to the form of correspondence from this HS-SCCH signaling decoding MIMO single-stream transmission resource control information; If the 1st bit in the channelization code information is got 1, the 5 bit and got 0, what then confirm this HS-SCCH signaling bear is MIMO stream transmission resource control information, according to the form of correspondence from this HS-SCCH signaling decoding MIMO stream transmission resource control information.If the 1st, 2,5 and 6 bits get 1,1,1 and 0 respectively in the channelization code information; What then confirm the HS-SCCH signaling bear is the CPC function control information, can further confirm that through the resource allocation cycle information in the channelization code information this HS-SCCH signaling is used for semi-continuous resource allocation type or temporary scheduling resource type.
Second kind of situation: adopt the signaling structure than traditional HS-SCCH signaling expanding, promptly length is greater than 46 bits.
Existed multiple length greater than 46 bits in the prior art; And the HS-SCCH signaling structure that is used for MIMO single current or stream transmission can directly adopt the HS-SCCH of this structure to carry MIMO single-stream transmission resource control information or MIMO stream transmission resource control information in the present invention.But because the length of the HS-SCCH signaling that is used for the CPC function that exists in the prior art is 46 bits; Therefore; The method that the present invention provides in this case mainly is the HS-SCCH signaling under the expansion CPC function, makes its length identical with HS-SCCH signaling length under the MIMO function, and provides method can adopt corresponding HS-SCCH signaling according to current functional requirement; Correspondingly, the terminal can be carried out the differentiation of function to the HS-SCCH that receives.
According to the different settings of channelization code information and modulation intelligence length, the HS-SCCH signaling also can adopt multiple length, lifts several embodiment below and respectively several kinds of typical length is described.
When 1) HS-SCCH signaling length was 54 bits, channelization code information was 8 bits in the HS-SCCH signaling under the MIMO function, and HAP is 4 bits, and its structure can be as shown in Figure 8, wherein comprised Mod, TBS and the RV information of two data flow respectively.Initial code value in the MIMO function lower channel sign indicating number information is less than or equal to the stop code value, and perhaps adopting the initial code value to identify SF greater than a special value in the stop code is 1.For example this sign SF is that 1 special value can be the reverse value of initial code and stop code, and promptly initial code is got maximum, and stop code is got the situation of minimum value, is example with this kind situation all in the following description, below gives unnecessary details no longer one by one.When 54 bits, sign SF be 1 initial code value be 15 and stop code be 0.For the MIMO single-stream transmission, the TBS territory of one of them data flow is set to 0, and correspondingly the Mod territory of this data flow and RV territory are invalid, for example, can be set to 0 by TBS2, and Mod2 territory and RV2 territory also relative set are 0; For the MIMO stream transmission, the TBS territory of two data flow correspondences is all effective.
Because the HS-SCCH signaling length under the existing CPC function is 46 bits; For fear of the UE blind check; The HS-SCCH signaling length that need be provided with under the CPC function also is 54 bits, at this moment, can before the HS-SCCH signaling format under original CPC function, increase the CPC sign of 8 bits; Constitute channelization code information jointly with original initial code and stop code, the structure of other information is identical with prior art.Wherein, the HS-SCCH structure that is used for semi-continuous resource allocation type under the CPC function is as shown in Figure 9, and the HS-SCCH structure that is used for the temporary scheduling resource type is shown in figure 10.
Because under this length, in the channelization code information to the MIMO function, the initial code value is less than or equal to stop code, perhaps, the initial code value be 15 and the stop code value be 0; Indicate the CPC function for the HS-SCCH with the MIMO function distinguishes, the value that preceding 4 bits in the CPC sign of 8 bits then are set is got 15 and 0 value when different with back 4 bits respectively greater than back 4 bits and preceding 4 bits.For example, can CPC sign be set among 11xx10xx, 11xx01xx, 10xx01xx or the 01xx00xx any one, wherein the x sign can be got arbitrary value, also can make reserved bit and use.
