Embodiment
For the purpose, technical scheme and the advantage that make the embodiment of the invention is clearer,, the technical scheme in the embodiment of the invention is clearly and completely described below in conjunction with the accompanying drawing in the embodiment of the invention.
Embodiment one
The flow chart of the processing method of the signature sequence that Fig. 1 provides for the embodiment of the invention one, as shown in Figure 1, the base station comprises the processing method of signature sequence in the present embodiment:
Step 101, base station obtain the signature sequence on the E-HICH according to the quantity that training in configuration information, training sequence deviation (Midamble Shift) and the sub-district, UE place allocated in advance to the scheduling E-PUCH of UE is offset.
In the present embodiment, UE is supported in the UE that adopts MU MIMO technology among the HSUPA.NodeB can be divided into training sequence deviation in the sub-district M group, shares identical scheduling E-PUCH resource to support M UE in MU MIMO mode.Wherein, the group number of M group training sequence deviation is respectively 0,1 ..., M-1.
Particularly, when the quantity of training sequence deviation in the sub-district is 2, M=2; When the quantity of training sequence deviation in the sub-district is 4,6,8,10,12,14 or 16, M=2 or M=4.The quantity of the training sequence deviation in the sub-district and the combination of the value of M can have 15 kinds (1+7*2=15).In every kind of value combination, m in the M group training sequence deviation i(Orthogonal Variable Spreading Factor, be called for short: OVSF) form with tree graph in the 3GPP agreement of the mapping relations between the channel code is defined for each training sequence deviation that comprises in the group training sequence deviation and each Orthogonal Variable Spreading Factor OVSF.Wherein, 0≤i≤M-1.Need to prove that at synchronization, the quantity of UE of sharing identical scheduling E-PUCH resource in MU MIMO mode is smaller or equal to M.
In the present embodiment, be K with the quantity of sharing the UE of identical scheduling E-PUCH resource in MU MIMO mode at synchronization UEIndividual, and K UEMaximum be that M is an example, introduce NodeB allocates training sequence deviation in advance to UE method in detail.This method is as follows:
For K UEI UE among the individual UE, NodeB can select m in the training sequence deviation in the M group iThe group training sequence deviation is then according to shared OVSF channel code and the m of scheduling E-PUCH that distributes to this UE iTraining sequence deviation that group comprises in the training sequence deviation and the mapping relations between the OVSF channel code determine to distribute to the training sequence deviation of this UE.It should be noted that other UE except above-mentioned i UE, all can not re-use m iThe group training sequence deviation.Wherein, 0≤i≤M-1.
Node B is determining to distribute to the scheduling E-PUCH of i UE and the group number m at training sequence deviation place iAfter, scheduling enhanced dedicated channel absolute grant channel (E-DCH Absolute GrantChannel from this UE, be called for short: E-AGCH) select an E-AGCH in the set, and pass through this E-AGCH the configuration information of scheduling E-PUCH and the group number m at training sequence deviation place iSend to this UE.
Each E-AGCH in its scheduling E-AGCH set of this UE monitoring.When UE listened to the E-AGCH that sends to it, UE can determine to distribute to its shared OVSF channel code of scheduling E-PUCH according to the configuration information of the E-PUCH that carries on this E-AGCH, and according to the group number m that carries on this OVSF channel code and the E-AGCH i, inquire about m iMapping relations between interior training sequence deviation and the OVSF channel code, thus determine to distribute to its training sequence deviation.UE will send the E-DCH transmission block to Node B by this training sequence deviation and scheduling E-PUCH.
Processing is deciphered to the E-DCH transmission block that the UE that receives sends in step 102, base station, and according to deciphering the result who handles, the signature sequence that in UE forwarding step 101, is obtained or the antitone sequence of signature sequence.
In the present embodiment,, then generate ACK information, and the antitone sequence of the signature sequence that obtained is sent to UE when Node B carries out correct decoding to the E-DCH transmission block that the UE that receives sends; The E-DCH transmission block that the UE that receives is sent as NodeB carries out mistake decoding, then generates nack message, and the signature sequence that is obtained is sent to UE.
Need to prove, UE can adopt above-mentioned base station to obtain the processing method of signature sequence, obtain the signature sequence on the E-HICH, thereby when UE detects the antitone sequence of the signature sequence that signature sequence that NodeB sends by E-HICH self obtains for this UE, UE determines that the feedback information that NodeB sends is an ACK information, and UE will no longer retransmit this E-DCH transmission block and give NodeB; When UE detect signature sequence that NodeB sends by E-HICH be UE self obtain signature sequence the time, UE determines that the feedback information that NodeB sends is a nack message.When the repeating transmission number of times of this transmission block does not reach maximum number of retransmissions, UE will retransmit this transmission block and give Node B.
In the present embodiment, NodeB is according to the quantity of training sequence deviation in configuration information, training sequence deviation and the sub-district, UE place allocated in advance to the scheduling E-PUCH of UE, obtain the signature sequence on the E-HICH, and the E-DCH transmission block that the UE that receives sends deciphered processing, according to decode results, send the former sequence of described signature sequence or the antitone sequence of the described signature sequence that obtains to UE; UE obtains signature sequence on the E-HICH according to the quantity of training sequence deviation in configuration information, training sequence deviation and the sub-district of the pre-assigned E-PUCH of NodeB, when the signature sequence that the NodeB that receives as UE sends was the antitone sequence of the signature sequence that UE obtained or former sequence, the feedback information that the NodeB that UE determines to receive sends was ACK information or nack message.Has different training sequence deviation owing to share each UE of identical scheduling E-PUCH resource, therefore the NodeB that proposes of present embodiment has solved the identical defective of signature sequence that NodeB in the prior art distributes to each UE that shares identical scheduling E-PUCH resource effectively to the processing method of signature sequence, simultaneously, the signature sequence of having realized distributing to the UE that supports MU MIMO technology does not effectively clash with the signature sequence of distributing to the UE that does not support MU MIMO technology.
Embodiment two
In the present embodiment, because the quantity of training sequence deviation can be 2,4,6,8,10,12,14 or 16 in the sub-district, and the quantity correspondence of different training sequence deviation is also inequality at the mapping relations tree graph between training sequence deviation and the OVSF channel code under the default training sequence deviation method of salary distribution, therefore, the quantity difference of training sequence deviation, the specific implementation of above-mentioned steps 101 can have following three kinds:
The quantity of training sequence deviation is 2,4,8 or 16 in first kind, sub-district, UE place, and then step 101 can be specially:
According to the timeslot number t that allocates in advance to last time slot of the configuration information of the scheduling E-PUCH of UE 0, the number k of training sequence deviation mQuantity K with training sequence deviation in the sub-district, UE place m, and formula (1):
r = 16 ( t 0 - 1 ) + ( k m - 1 ) 16 K m - - - ( 1 )
Obtain the pairing signature sequence of logical identifier r of the signature sequence of E-HICH;
Wherein, t 0, k mAnd K mBe positive integer; And 1≤k m≤ K m
The quantity of training sequence deviation is 6 in second kind, sub-district, UE place; Then step 101 can also be specially:
If 1≤k m≤ 4, then according to the timeslot number t that allocates in advance to last time slot of the configuration information of the scheduling E-PUCH of UE 0, the number k of training sequence deviation mQuantity K with training sequence deviation in the sub-district, UE place m, and formula (2):
r＝16(t 0-1)+2(k m-1) (2)
Obtain the pairing signature sequence of logical identifier r of the signature sequence on the E-HICH; Perhaps
If 5≤k m≤ K m, then according to the timeslot number t that allocates in advance to last time slot of the configuration information of the scheduling E-PUCH of UE 0, the number k of training sequence deviation mQuantity K with training sequence deviation in the sub-district, UE place m, and formula (3):
r＝16(t 0-1)+4(k m-3) (3)
Obtain the pairing signature sequence of logical identifier r of the signature sequence on the E-HICH;
Wherein, t 0, k mAnd K mBe positive integer.
The third: the quantity of training sequence deviation is 10,12 or 14 in the sub-district, UE place, and step 101 can also be specially:
If 1≤k m≤ K m-a is then according to the timeslot number t that allocates in advance to last time slot of the configuration information of the scheduling E-PUCH of UE 0, the number k of training sequence deviation mQuantity K with training sequence deviation in the sub-district, UE place m, and formula (4):
r＝16(t 0-1)+(k m-1) (4)
Obtain the pairing signature sequence of logical identifier r of the signature sequence on the E-HICH; Perhaps
If K m-a+1≤k m≤ K m, then according to the timeslot number t that allocates in advance to last time slot of configuration information of the scheduling E-PUCH of UE 0, the number k of training sequence deviation mQuantity K with training sequence deviation in the sub-district, UE place m, and formula (5):
r＝16(t 0-1)+2(k m-9+a) (5)
Obtain the pairing signature sequence of logical identifier r that strengthens the signature sequence on the dedicated channel hybrid automatic repeat request indication channel;
Wherein, t 0, k mAnd K mBe positive integer, and a=16modK m
Particularly, the computing formula that logical identifier adopted (1) of obtaining signature sequence to the concrete acquisition mode of formula (5) can for:
If according to the quantity of training sequence deviation in configuration information, training sequence deviation and the sub-district, UE place allocated in advance to the scheduling E-PUCH of UE, obtain the formula that the logical identifier (ID) of the signature sequence on the E-HICH adopted and to be expressed as r=f (t 0, k m), wherein, t 0Be the timeslot number of last time slot of the configuration information of the E-PUCH that distributes to UE, k mThe number of training sequence deviation of UE is distributed in expression, and r represents to distribute to the logic ID of the signature sequence of UE.
In the present embodiment, obtain the formula r=f (t that logic ID adopted of the signature sequence on the E-HICH 0, k m) need satisfy following two conditions:
First condition, for each UE that shares identical E-PUCH resource, adopt formula r=f (t 0, k m) signature sequence of distributing to different UEs that obtains must be different.
Second condition, adopt formula r=f (t 0, k m) signature sequence of distributing to the UE that supports MU MIMO that obtains can not clash with the signature sequence of distributing to the UE that does not support MU MIMO.So-called conflict is meant that for two different UE a UE does not support MU MIMO technology, and another UE supports MU MIMO technology; The logic ID of the signature sequence that calculates according to the distribution method of existing signature sequence according to the E-PUCH configuration information of resource of distributing to it for the UE that does not support MU MIMO technology and the UE that supports MU MIMO technology are according to formula r=f (t 0, k m) logic ID of the signature sequence that calculates is identical.When above-mentioned conflict takes place, NodeB can occur and feed back the ACK/NACK information of two dissimilar UE by same signature sequence, cause the obscuring of ACK/NACK information of two UE.
In order to guarantee formula r=f (t 0, k m) satisfy as above two conditions, need be according to training sequence deviation quantity K in the sub-district, UE place m, in the 3GPP agreement, search this K mBe worth training sequence deviation under the pairing default training sequence deviation method of salary distribution and the mapping relations tree graph between the OVSF channel code.In this tree graph, obtain the OVSF channel code of minimum particle size, be specially: after the OVSF channel code that will have the same spread factor in pairing each channel code of any one training sequence deviation is removed, select the OVSF channel code of spreading factor maximum, selected OVSF channel code is exactly the OVSF channel code of the pairing minimum particle size of this training sequence deviation.
Below with K m=8 is example, illustrates definite method of minimum particle size channel code.Fig. 2 is K mMapping relations tree graph under=8 o'clock default training sequence deviation methods of salary distribution between training sequence deviation and the OVSF channel code.As shown in Figure 2, corresponding two SF of each training sequence deviation are 16 channel code, therefore, in the pairing channel code of this training sequence deviation be that 16 channel code is removed with two SF, select the channel code of spreading factor maximum then, the channel code of this spreading factor maximum is the OVSF channel code of SF=8.That is: 8 training sequence deviation m (1), m (2)..., m (8)In i training sequence deviation m (i)Corresponding minimum particle size channel code is:
Figure BSA00000157632200101
Wherein,
Figure BSA00000157632200102
The expression spreading factor is Q 0, channel code sign indicating number number is q 0The OVSF channel code;
Figure BSA00000157632200103
Expression training sequence deviation number is k mTraining sequence deviation.
If UE does not support MU MIMO, the timeslot number of last time slot of distributing to the E-PUCH of UE is t 0, when being Q with a spreading factor 0The channel code q of minimum particle size 0When distributing to UE, UE is according to the formula of existing method
Figure BSA00000157632200104
To calculate the logic ID of a signature sequence, represent this logic ID value with " r1 ".The channel code q of this minimum particle size 0Corresponding uniquely training sequence deviation k under the default training sequence deviation method of salary distribution mTimeslot number t with last time slot of E-PUCH 0Number k with this training sequence deviation mSubstitution formula r=f (t 0, k m) in, also will calculate the logic ID of a signature sequence, represent this logic ID value with " r2 ".If make r1=r2 that the channel code of any one minimum particle size is all set up, then formula r=f (t 0, k m) processing method of represented signature sequence necessarily satisfies above-mentioned two conditions.Its reason is as follows:
The number q of the OVSF channel code of different minimum particle size 0The number k of corresponding different training sequence deviation m, and the OVSF channel code that travels through each minimum particle size will travel through all K mIndividual training sequence deviation is according to formula
Figure BSA00000157632200111
The number q of the OVSF channel code of different minimum particle size 0The logic ID of the signature sequence that inevitable correspondence is different.Therefore, when satisfying r1=r2, r=f (t 0, k m) must satisfy: with different training sequence deviation substitution r=f (t 0, k m) must obtain the logic ID of different signature sequences.So the signature sequence of distributing to each UE that shares identical E-PUCH resource is different because the training sequence deviation of these UE is different.Therefore, under r1=r2, function r=f (t 0, k m) must satisfy first condition.
No matter UE supports MU MIMO technology or does not support MU MIMO technology, and the training sequence deviation of distributing to different UEs is different certainly, and therefore, can obtain: the UE that does not support MU MIMO technology is according to formula
Figure BSA00000157632200112
The logic ID of the signature sequence that calculates can not with the UE that supports MU MIMO technology according to formula r=f (t 0, k m) logic ID of the signature sequence that calculates is identical.Therefore, under r1=r2, function r=f (t 0, kM) second condition that must satisfy condition.
Based on above-mentioned analysis, to each K mValue is determined this K mThe number q of any one channel code under the value in the OVSF channel code of each minimum particle size 0, determine the spreading factor Q of this channel code 0Number k with the training sequence deviation of this channel code correspondence m, determine function r=f (t according to following formula 0, k m) be t at the timeslot number of last time slot of the E-PUCH that distributes to UE 0And the number of distributing to the training sequence deviation of UE is k mThe time distribute to the logic ID of the signature sequence of this UE:
r = f ( t 0 , k m ) = 16 ( t 0 - 1 ) + ( q 0 - 1 ) 16 Q 0 - - - ( 6 )
Because the quantity K of training sequence deviation in the sub-district mCan be 2,4,6,8,10,12,14 and 16, and different K mUnder the tree graph difference, different K mThe channel code of following minimum particle size is not necessarily identical, and then present embodiment will divide following three kinds of situations to determine formula r=f (t 0, k m) the formula that embodies.
The quantity of training sequence deviation is 2,4,8 or 16 in first kind, sub-district, UE place;
The quantity of training sequence deviation is 6 in second kind, sub-district, UE place;
The third, the quantity of training sequence deviation is 10,12,14 in the sub-district, UE place;
Work as K m=2,4,8 and 16 o'clock, according to these K mValue can be found: these K at the mapping relations tree graph between pairing training sequence deviation and the OVSF channel code under the default training sequence method of salary distribution mValue is the number q of the OVSF channel code of minimum particle size down 0Number k with the pairing training sequence deviation of this channel code mBetween satisfy relational expression: q 0=k m, and the spreading factor Q of the OVSF channel code correspondence of this minimum particle size 0Quantity K with training sequence deviation mBetween satisfy relational expression: K m=Q 0
If distributing to the timeslot number of last time slot of the E-PUCH of UE is t 0, the number of distributing to the OVSF channel code of UE is q 0, with q 0=k mAnd K m=Q 0Substitution formula (6):
r = 16 ( t 0 - 1 ) + ( q 0 - 1 ) 16 Q 0 - - - ( 6 )
Obtain formula (1):
r = 16 ( t 0 - 1 ) + ( k m - 1 ) 16 K m - - - ( 1 )
Wherein, formula (6) is not for when supporting MU MIMO technology among the HSUPA, NodeB obtains the computational methods that E-HICH goes up signature sequence according to the number of timeslot number, spreading factor and the OVSF channel code of last time slot in the configuration information of the scheduling E-PUCH of distributing to UE.
Formula (1) is exactly K m=2,4,8 and 16 o'clock, function r=f (t 0, k m) expression formula.Wherein, t 0, k mAnd K mBe positive integer; And 1≤k m≤ K m
Work as K m=6 o'clock, according to this K mValue can be found at the mapping relations tree graph between pairing training sequence deviation and the OVSF channel code under the default training sequence method of salary distribution: preceding four training sequence deviation m (k), k=1, the channel code of the minimum particle size of 2,3,4 correspondences is that spreading factor is Q 0=8 channel code, the number q of any one channel code in these channel code 0Number k with the training sequence deviation of this channel code correspondence mBetween satisfy: k m=q 0Latter two training sequence deviation m (k), k=5, the channel code of the minimum particle size of 6 correspondences is that spreading factor is Q 1=4 channel code, and any one training sequence deviation k in these two training sequence deviation mChannel code number q with the pairing minimum particle size of this training sequence deviation 1Between satisfy: q 1=k m-2.
Work as K m=6 and 1≤k m≤ 4 o'clock, the timeslot number of establishing last time slot of the E-PUCH that distributes to UE was t 0, the channel code of distributing to UE is q 0=k m, and q 0Spreading factor be Q 0=8, with t 0, q 0=k mAnd Q 0=8 substitution formula (6):
r = 16 ( t 0 - 1 ) + ( q 0 - 1 ) 16 Q 0 - - - ( 6 )
Obtain formula (2):
r＝16(t 0-1)+2(k m-1) (2)
Perhaps,
Work as K m=6 and 5≤k m≤ K mThe time, the timeslot number of establishing last time slot of the E-PUCH that distributes to UE is t 0, the channel code of distributing to UE is q 1=k m-2, and q 1Spreading factor be Q 1=4, with t 0, q 1=k m-2 and Q 1=4 substitution formula (6):
