Description

Signature sequence processing method and system, user equipment and base station

Technical Field

The embodiment of the invention relates to the technical field of communication, in particular to a method and a system for processing a signature sequence, user equipment and a base station.

Background

High Speed Uplink Packet Access (HSUPA) is an enhanced technique for increasing Uplink throughput and Uplink peak rate in a Time Division Synchronous Code Division Multiple Access (TD-SCDMA) system. The HSUPA greatly improves the uplink throughput and the uplink peak rate of a single cell and greatly improves the uplink frequency spectrum utilization rate of the TD-SCDMA system through key technologies such as fast scheduling, an automatic retransmission request process, interference control and the like.

The automatic repeat request process is a physical layer packet retransmission mechanism in HSUPA. Retransmission of data packets is performed between a User Equipment (UE) and a base station (NodeB). The NodeB determines a logical ID of a signature sequence on an enhanced dedicated Channel Hybrid automatic repeat request indicator Channel (E-DCH Hybrid ARQ indicator Channel, abbreviated as E-HICH) according to configuration information of an enhanced dedicated Channel Physical Uplink Channel (E-PUCH) allocated to the UE. Specifically, the Node B acquires the logical identifier of the signature sequence on the E-HICH according to the time slot number, the spreading factor and the channel code number of the last time slot in the configuration information of the scheduling E-PUCH allocated to the UE. It should be noted that the logical identifier of each signature sequence uniquely corresponds to a signature sequence on the E-HICH.

If the NodeB correctly decodes the received Enhanced dedicated channel (E-DCH) transmission block sent by the UE, generating Acknowledgement (ACK) information and feeding back the determined reverse sequence of the signature sequence to the UE through an E-HICH; if the NodeB decodes the transmission block in error, generating Non-acknowledgement (NACK) information, and feeding back the determined original sequence of the signature sequence to the UE through the E-HICH. When the UE detects that the sequence fed back by the NodeB through the E-HICH is an anti-sequence or an original sequence of the corresponding sequence, the information fed back by the NodeB can be determined to be ACK information or NACK information. When the UE determines that the information fed back by the NodeB is ACK information, the UE does not resend the E-DCH transmission block; when the UE determines that the information fed back by the NodeB is NACK information, the UE will resend the E-DCH transport block if the transport block does not reach the maximum number of retransmissions. Wherein, the original sequence is the signature sequence.

In the process of implementing the invention, the inventor finds that at least the following problems exist in the prior art: when HSUPA supports a multi-User (MU) Multiple Input Multiple Output (MIMO) technology, different UEs may share the same scheduling E-PUCH resource, so that the following occurs: the configuration information of scheduling E-PUCHs allocated by the NodeB to multiple UEs is the same, which may further cause: the NodeB feeds back the ACK/NACK information of the E-DCH transport blocks of the UEs sharing the same E-PUCH resources through the same signature sequence, so it may result in: confusion of ACK/NACK information of individual UEs.

Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention.

Example one

Fig. 1 is a flowchart of a method for processing a signature sequence according to an embodiment of the present invention, and as shown in fig. 1, the method for processing the signature sequence by a base station in this embodiment includes:

step 101, a base station acquires a signature sequence on an E-HICH according to configuration information of a scheduling E-PUCH pre-allocated to UE, a training sequence Shift (Midamble Shift) and the number of the training shifts in a cell where the UE is located.

In this embodiment, the UE is a UE supporting the MU MIMO technology in HSUPA. The NodeB may divide the intra-cell training sequence offsets into M groups to support M UEs to share the same scheduled E-PUCH resources in a MU MIMO manner. Wherein, the group numbers of the M groups of training sequence offsets are 0, 1.

Specifically, when the number of the intra-cell training sequence offsets is 2, M is 2; when the number of the intra-cell training sequence offsets is 4, 6, 8, 10, 12, 14 or 16, M-2 or M-4. The number of midamble offsets in a cell, combined with the value of M, can be 15 (1+7 × 2 ═ 15). In each value combination, the M-th training sequence in M groups of training sequence offsets_iIn group training sequence offsetThe mapping relationship between the training sequence offsets and the Orthogonal Variable Spreading Factor (OVSF) channel codes is defined in the 3GPP protocol in the form of a tree. Wherein i is more than or equal to 0 and less than or equal to M-1. At the same time, the number of UEs sharing the same scheduling E-PUCH resource in MU MIMO is equal to or less than M.

In this embodiment, the number of UEs sharing the same scheduling E-PUCH resource in MU MIMO mode at the same time is K_UEEach, and K_UEFor example, the method of the NodeB pre-allocating the midamble offset to the UE is described in detail. The method comprises the following steps:

for K_UEOf the UEs, the NodeB may select the mth UE among the training sequence offsets in the M sets_iGroup training sequence offset, then according to OVSF channel code occupied by scheduling E-PUCH allocated to the UE and m_iAnd determining the training sequence offset allocated to the UE according to the mapping relation between the training sequence offset included in the group of training sequence offsets and the OVSF channel code. It should be noted that, the m-th UE can not be used by any other UE except the i-th UE_iThe set of training sequence offsets. Wherein i is more than or equal to 0 and less than or equal to M-1.

Node B determines group number m of scheduling E-PUCH and training sequence offset distributed to ith UE_iThen, selecting one E-AGCH from the set of scheduling enhanced dedicated channel Absolute grant channels (E-AGCH) of the UE, and scheduling the configuration information of the E-PUCH and the group number m of the training sequence offset through the E-AGCH_iAnd sending the information to the UE.

The UE listens to each E-AGCH in its set of scheduling E-AGCHs. When the UE monitors the E-AGCH sent to the UE, the UE can determine the OVSF channel code occupied by the scheduling E-PUCH according to the configuration information of the E-PUCH carried on the E-AGCH, and the OVSF channel code and the group number m carried on the E-AGCH_iM, inquires about_iMapping between inner training sequence offset and OVSF channel code to determine assignmentGiving it a training sequence offset. The UE will send E-DCH transport block to Node B by the training sequence offset and scheduling E-PUCH.

And 102, the base station decodes the received E-DCH transport block sent by the UE and sends the signature sequence or the anti-sequence of the signature sequence acquired in the step 101 to the UE according to the decoding result.

In this embodiment, when the Node B correctly decodes the received E-DCH transport block sent by the UE, it generates ACK information and sends the obtained anti-sequence of the signature sequence to the UE; and when the NodeB carries out error decoding on the received E-DCH transmission block sent by the UE, generating NACK information and sending the acquired signature sequence to the UE.

It should be noted that the UE may acquire the signature sequence on the E-HICH by using the processing method for acquiring the signature sequence by the base station, so that when the UE detects that the signature sequence transmitted by the NodeB through the E-HICH is an inverse sequence of the signature sequence acquired by the UE itself, the UE determines that the feedback information transmitted by the NodeB is ACK information, and the UE will not retransmit the E-DCH transport block to the NodeB; and when the UE detects that the signature sequence sent by the NodeB through the E-HICH is the signature sequence acquired by the UE, the UE determines that the feedback information sent by the NodeB is NACK information. When the retransmission times of the transmission block does not reach the maximum retransmission times, the UE retransmits the transmission block to the Node B.

In this embodiment, a NodeB acquires a signature sequence on an E-HICH according to configuration information of a scheduling E-PUCH pre-allocated to a UE, a training sequence offset, and the number of the training sequence offsets in a cell where the UE is located, decodes a received E-DCH transport block transmitted by the UE, and transmits an original sequence of the signature sequence or an inverted sequence of the acquired signature sequence to the UE according to a decoding result; and the UE acquires the signature sequence on the E-HICH according to the configuration information, the training sequence offset and the number of the training sequence offsets in the cell, which are pre-allocated by the NodeB, and when the signature sequence received by the UE and sent by the NodeB is the reverse sequence or the original sequence of the signature sequence acquired by the UE, the UE determines that the received feedback information sent by the NodeB is ACK information or NACK information. Because each UE sharing the same scheduling E-PUCH resource has a different midamble offset, the method for processing a signature sequence by a NodeB according to this embodiment effectively solves the defect in the prior art that the signature sequences allocated by the NodeB to each UE sharing the same scheduling E-PUCH resource are the same, and at the same time, effectively achieves that the signature sequence allocated to the UE supporting the MU MIMO technique does not collide with the signature sequence allocated to the UE not supporting the MU MIMO technique.

Example two

In this embodiment, since the number of the midamble offsets in the cell may be 2, 4, 6, 8, 10, 12, 14, or 16, and the mapping tree between the midamble offsets and the OVSF channel codes in the default midamble offset allocation manner corresponding to the number of different midamble offsets are also different, the number of the midamble offsets is different, and the specific implementation manner of the step 101 may include the following three types:

first, the number of the midamble offsets in the cell where the UE is located is 2, 4, 8, or 16, then step 101 may specifically be:

a slot number t of a last slot according to configuration information of a scheduling E-PUCH pre-allocated to the UE₀Number k of training sequence offset_mAnd the number K of training sequence offsets in the cell in which the UE is located_mAnd formula (1):

$r=16(t_0-1)+(k_m-1)\frac{16}{K_m}---\left(1\right)$

acquiring a signature sequence corresponding to a logic identifier r of the signature sequence of the E-HICH;

wherein, t₀、k_mAnd K_mIs a positive integer; and k is not less than 1_m≤K_m。

Secondly, the number of the training sequence offsets in the cell where the UE is located is 6; then step 101 may also specifically be:

if 1 is less than or equal to k_mIf the time slot number t is less than or equal to 4, the time slot number t of the last time slot of the configuration information of the scheduling E-PUCH pre-allocated to the UE is determined₀Number k of training sequence offset_mAnd the number K of training sequence offsets in the cell in which the UE is located_mAnd formula (2):

r＝16(t₀-1)+2(k_m-1) (2)

acquiring a signature sequence corresponding to a logic identifier r of the signature sequence on the E-HICH; or

If k is not less than 5_m≤K_mThen, according to the time slot number t of the last time slot of the configuration information of the scheduling E-PUCH pre-allocated to the UE₀Number k of training sequence offset_mAnd the number K of training sequence offsets in the cell in which the UE is located_mAnd formula (3):

r＝16(t₀-1)+4(k_m-3) (3)

acquiring a signature sequence corresponding to a logic identifier r of the signature sequence on the E-HICH;

wherein, t₀、k_mAnd K_mIs a positive integer.

And the third is that: the number of the training sequence offsets in the cell where the UE is located is 10, 12, or 14, and step 101 may further specifically be:

if 1 is less than or equal to k_m≤K_mA, the time slot number t of the last time slot according to the configuration information of the scheduling E-PUCH pre-allocated to the UE₀Number k of training sequence offset_mAnd the number K of training sequence offsets in the cell in which the UE is located_mAnd formula (4):

r＝16(t₀-1)+(k_m-1) (4)

acquiring a signature sequence corresponding to a logic identifier r of the signature sequence on the E-HICH; or

If K_m-a+1≤k_m≤K_mThen according to the configuration information of the scheduling E-PUCH pre-allocated to the UE, the time slot number t of the last time slot₀Number k of training sequence offset_mAnd the number K of training sequence offsets in the cell in which the UE is located_mAnd formula (5):

r＝16(t₀-1)+2(k_m-9+a) (5)

acquiring a signature sequence corresponding to a logic identifier r of the signature sequence on an enhanced dedicated channel hybrid automatic repeat request indicator channel;

wherein, t₀、k_mAnd K_mIs a positive integer, and a is 16modK_m。

Specifically, the specific obtaining manner of the calculation formulas (1) to (5) adopted for obtaining the logical identifier of the signature sequence may be as follows:

a formula adopted for obtaining a logical Identifier (ID) of a signature sequence on an E-HICH according to configuration information of a scheduling E-PUCH pre-allocated to a UE, a midamble offset, and the number of midamble offsets in a cell where the UE is located may be represented as r ═ f (t ═ f)₀，k_m) Wherein, t₀The slot number, k, of the last slot of the configuration information for the E-PUCH allocated to the UE_mDenotes the number of the training sequence offset assigned to the UE, and r denotes the logical ID of the signature sequence assigned to the UE.

In this embodiment, the formula r ═ f (t) used to obtain the logical ID of the signature sequence on the E-HICH₀，k_m) The following two conditions need to be satisfied:

the first condition is that for each UE sharing the same E-pucch resource, the formula r ═ f (t) is used₀，k_m) The acquired signature sequences assigned to different UEs must be different.

The second condition is that the formula r ═ f (t) is adopted₀，k_m) The acquired signature sequence allocated to the UE supporting MU MIMO does not collide with the signature sequence allocated to the UE not supporting MU MIMO. The conflict refers to that for two different UEs, one UE does not support the MU MIMO technology, and the other UE supports the MU MIMO technology; for the UE which does not support the MU MIMO technology, the logic ID of the signature sequence obtained by calculation according to the configuration information of the E-PUCH resource distributed to the UE and the UE which supports the MU MIMO technology according to the distribution method of the existing signature sequence is f (t) according to the formula r₀，k_m) The logical IDs of the calculated signature sequences are the same. When the above-mentioned collision occurs, it may happen that the NodeB feeds back ACK/NACK information of two different types of UEs through the same signature sequence, causing confusion of ACK/NACK information of the two UEs.

To ensure that the formula r ═ f (t)₀，k_m) The above two conditions are satisfied, and the offset number K of the training sequence in the cell where the UE is located is required to be determined_mLooking up the K in the 3GPP protocol_mAnd the mapping relation tree diagram between the training sequence offset and the OVSF channel code under the default training sequence offset distribution mode corresponding to the value. In the tree diagram, acquiring the OVSF channel code with the minimum granularity specifically includes: after the OVSF channel codes with the same spreading factor are removed from each channel code corresponding to any training sequence offset, the OVSF channel code with the largest spreading factor is selected, and the selected OVSF channel code is the OVSF channel code with the smallest granularity corresponding to the training sequence offset.

Below with K_mFor example, 8 illustrates the smallest granularity channel codeAnd determining a method. FIG. 2 is K_mAnd 8, the mapping relation tree graph between the training sequence offset and the OVSF channel code under the default training sequence offset distribution mode. As shown in fig. 2, each midamble offset corresponds to two SF 16 channel codes, so that two SF 16 channel codes are removed from the channel codes corresponding to the midamble offset, and then the channel code with the largest spreading factor is selected, which is the OVSF channel code with SF-8. Namely: 8 training sequence offsets m⁽¹⁾，m⁽²⁾，......，m⁽⁸⁾The ith training sequence offset m⁽ⁱ⁾The corresponding minimum granularity channel code is:

wherein,

indicating a spreading factor of Q₀Channel code number q₀The OVSF channel code of (1);

indicates training sequence offset number k_mThe training sequence offset of (1).

The UE does not support MU MIMO, and the time slot number of the last time slot of the E-PUCH allocated to the UE is t₀When a spreading factor is Q₀Of the smallest granularity of the channel code q₀When allocated to a UE, the UE follows the formula of the existing method

The logical ID of a signature sequence will be calculated and the value of the logical ID will be denoted by "r 1". The channel code q of the minimum granularity₀Uniquely corresponding to a midamble shift k in a default midamble shift allocation manner_m. The time slot number t of the last time slot of the E-PUCH is compared with the time slot number t of the last time slot of the E-PUCH₀And the number k of the training sequence offset_mSubstituting the formula r ═ f (t)₀，k_m) The logical ID of a signature sequence is also calculated, and the logical ID value is denoted by "r 2". If r1 is r2 for any oneThe smallest granularity channel code holds, and the formula r ═ f (t)₀，k_m) The processing method of the represented signature sequence must satisfy the above two conditions. The reason for this is as follows:

number q of OVSF channel codes of different minimum granularity₀Number k corresponding to different midamble shifts_mAnd traversing each minimum granularity OVSF channel code will traverse all K_mAn offset of training sequence according to the formula

Number q of OVSF channel codes of different minimum granularity₀Necessarily corresponding to the logical ID of the different signature sequences. Therefore, when r1 is r2, r is f (t)₀，k_m) It is inevitable to satisfy: substituting different training sequence offsets into r ═ f (t)₀，k_m) The logical IDs of the different signature sequences must be obtained. Therefore, the signature sequences allocated to the respective UEs sharing the same E-PUCH resource are different due to the different training sequence offsets of the UEs. Thus, at r 1-r 2, the function r-f (t)₀，k_m) The first condition must be satisfied.

No matter whether the UE supports MU MIMO technology or does not support MU MIMO technology, the training sequence offsets assigned to different UEs are definitely different, and therefore, it can be obtained: UE which does not support MU MIMO technology according to formula

The calculated logical ID of the signature sequence cannot be matched with the UE supporting the MU MIMO technology according to the formula r ═ f (t)₀，k_m) The logical IDs of the calculated signature sequences are the same. Thus, at r 1-r 2, the function r-f (t)₀，_km) necessarily satisfies the second condition.

Based on the above analysis, for each K_mValue, determining the K_mNumber q of any one of OVSF channel codes of minimum granularity under the value₀Determining the spreading factor Q of the channel code₀Training corresponding to the channel codeNumber k of sequence offsets_mThe function r ═ f (t) is determined as follows₀，k_m) The time slot number of the last time slot of the E-PUCH allocated to the UE is t₀And the number of the training sequence offset allocated to the UE is k_mLogical ID of signature sequence assigned to the UE:

$r=f(t_0,k_m)=16(t_0-1)+(q_0-1)\frac{16}{Q_0}---\left(6\right)$

due to the number of intra-cell training sequence offsets, K_mCan be 2, 4, 6, 8, 10, 12, 14 and 16, and different in K_mThe lower tree diagrams are different, different K_mIf the channel codes with the lowest granularity are not necessarily the same, the present embodiment will determine the formula r ═ f (t) according to the following three cases₀，k_m) The specific expression of (1).

Firstly, the number of the training sequence offsets in the cell in which the UE is located is 2, 4, 8 or 16;

secondly, the number of the training sequence offsets in the cell where the UE is located is 6;

thirdly, the number of the training sequence offsets in the cell where the UE is located is 10, 12 and 14;

when K is_mWhen 2, 4, 8 and 16, according to these K_mThe tree diagram of the mapping relationship between the training sequence offset corresponding to the value in the default training sequence allocation mode and the OVSF channel code can find that: these K_mNumber q of OVSF channel code of minimum granularity under value₀Number k of midamble offset corresponding to the channel code_mSatisfies the relation: q. q.s₀＝k_mAnd the spread factor Q corresponding to the OVSF channel code with the minimum granularity₀And the number of training sequence offsets K_mSatisfies the relation: k_m＝Q₀。

Setting a time slot number of a last time slot of an E-PUCH allocated to a UE as t₀The number of OVSF channel codes assigned to the UE is q₀Q is prepared by₀＝k_mAnd K_m＝Q₀Substituting formula (6):

$r=16(t_0-1)+(q_0-1)\frac{16}{Q_0}---\left(6\right)$

obtaining formula (1):

$r=16(t_0-1)+(k_m-1)\frac{16}{K_m}---\left(1\right)$

formula (6) is a calculation method for acquiring a signature sequence on an E-HICH by a NodeB according to a timeslot number of a last timeslot, a spreading factor and a number of an OVSF channel code in configuration information of a scheduling E-PUCH allocated to a UE when an MU MIMO technology is not supported in HSUPA.

The formula (1) is K_mWhen 2, 4, 8 and 16, the function r is f (t)₀，k_m) Is described in (1). Wherein, t₀、k_mAnd K_mIs a positive integer; and k is not less than 1_m≤K_m。

EXAMPLE III

Fig. 3 is a flowchart of a processing method of a signature sequence according to a third embodiment of the present invention, and as shown in fig. 3, the processing method of a signature sequence by a ue according to the present embodiment includes:

step 201, obtaining a first signature sequence on the E-HICH according to configuration information of the E-PUCH pre-allocated by the NodeB, training sequence offset and the number of the training sequence offset in the cell where the NodeB is located.

In this embodiment, the implementation manner of step 201 is similar to that of step 101 shown in fig. 1, and is not described here again.

Step 202, according to the first signature sequence and the received second signature sequence sent by the Node B, performing judgment, and according to a judgment result, determining whether the received feedback information sent by the Node B is ACK information or NACK information.

In this embodiment, when the UE determines that the received second signature sequence sent by the Node B is an inverted sequence of the first signature sequence, it determines that the received feedback information sent by the Node B is ACK information; and when the UE judges that the received second signature sequence sent by the Node B is the first signature sequence, the received feedback information sent by the Node B is determined to be NACK information.

In this embodiment, a Node B acquires a signature sequence on an E-HICH according to configuration information of a scheduling E-PUCH pre-allocated to a UE, a training sequence offset, and a number of the training sequence offsets in a cell where the UE is located, decodes a received E-DCH transport block transmitted by the UE, and transmits an original sequence of the acquired signature sequence or an inverted sequence of the acquired signature sequence to the UE according to a decoding processing result, where the signature sequence acquired by the Node B is the same as a first signature sequence acquired by the UE in the following description; the UE acquires a first signature sequence on the E-HICH according to configuration information, training sequence offset and the number of the training sequence offset in a cell pre-allocated by the NodeB, and when a second signature sequence received by the UE and sent by the Node B is an inverse sequence or an original sequence of the first signature sequence acquired by the UE, the UE determines that feedback information sent by the NodeB is ACK information or NACK information, and because each UE sharing the same scheduling E-PUCH resource has different training sequence offsets, the method for processing the signature sequence by the user equipment effectively overcomes the defect that the signature sequences allocated by the NodeB to each UE sharing the same scheduling E-PUCH resource are the same in the prior art, and simultaneously effectively realizes that the signature sequence allocated to the UE supporting the MIMO MU technology does not conflict with the signature sequence allocated to the UE not supporting the MU MIMO technology, and avoids confusion of ACK/NACK information of individual UEs.

Further, since the number of the midamble shifts in the cell where the ue is located may be 2, 4, 6, 8, 10, 12, 14, or 16, and the tree maps of the mapping relationship between the midamble shifts and the OVSF channel codes in the default midamble shift allocation manner corresponding to the number of different midamble shifts are also different, the number of midamble shifts is different, and there may be three specific implementation manners of the step 201, which are the same as the three implementation manners of the step 101 shown in fig. 1, and are not described herein again. Please refer to the specific implementation of step 101 given in example two for the specific implementation of step 201.
