Technical field
The present invention relates to G mobile communication field, particularly relate to all E-PUCH when sharing E-HICH, E-
The distribution method of HICH signature sequence.
Background technology
TD-SCDMA (Time Division-Synchronous Code Division Multiple Access, time
Point-S-CDMA-Synchronous Code Division Multiple Access accesses) system is one of the third generation (3G) mobile communication system standard, by third generation partnership projects (3rd
Generation Partner Project) standardization body is standardized work to it.TD-SCDMA system uses the time-division
Duplex (Time Division Duplex) mode, i.e. sends and receives operation and carry out in different time intervals respectively, on
Line link and downlink use identical frequency range.
HSDPA (High Speed Downlink Packet Access, high-speed slender body theory) is a kind of raising
The technology of cdma system downlink transmission data rate, is that 3GPP standardization body is asymmetric in order to meet up-downgoing data service
Demand proposes in the standard of Release 5 version, can be under the existing TD-SCDMA system network architecture, by single carrier
User's downlink business peak rate brings up to 2.8Mbps.In order to improve the downlink service data in TD-SCDMA system further
Transfer rate, TD-SCDMA standard introduces multi-transceiver technology, makes a TD-SCDMA community can support on multiple carrier wave
It is wirelessly transferred.This TD-SCDMA multi-carrier HSDPA community can provide the peak-data speed of about N times single carrier HSDPA
Rate, wherein N is the number of the supported carrier wave in community, thus is remarkably improved single community and cell throughout.
The Chief that HSUPA (High Speed Uplink Packet Access, high speed uplink packet accesses) uses
Technology is similar with HSDPA, i.e. adaptive coding and modulating (AMC), high order modulation (16QAM), mixing automatic repeat request (HARQ),
Fast dispatch etc..HSUPA can be used to improve uplink transmission rate and resource utilization, improves Consumer's Experience.
Include that (Enhanced-Physical Uplink Channel strengthens ascending physical signal to two kinds of E-PUCH at HSUPA
Channel), the E-PUCH and non-scheduled E-PUCH of scheduling.The E-PUCH resource of scheduling is distributed in real time by Node B, passes through E-
AGCH (E-DCH Absolute Grant Channel, the absolute grant channel of E-DCH) informs UE (subscriber equipment) E-
Other information required for the time slot at PUCH place, code channel and decoding, UE sends signal on the E-PUCH that Node B authorizes
After, (E-DCH HARQ Acknowledgement Indicator Channel, E-DCH HARQ is true by E-HICH for Node B
Recognize instruction channel) feeding back ACK/nack message is to UE.Non-scheduled E-PUCH resource is by RNC (Radio Network
Controller, radio network controller) configured by high-level signaling, the E-HICH signature sequence that non-scheduled E-PUCH is used
Also configured by high-level signaling by RNC.For non-scheduled transmission, E-HICH not only carries HARQ response instruction (ACK/NACK),
Also carrying TPC and SS order.80 signature sequences are divided into 20 groups, often 4 sequences of group.High level only divides for each non-scheduled users
Join one group.In these 4 sequences, first sequence is used to refer to ACK/NACK, and other three are used to refer to TPC/SS order.This
Three sequences and their three reversion sequences are used to indicate six kinds of possible sequences of TPC/SS assembled state.Reversion sequence
It is by each bit of sequence being become 1 from 0 or becoming 0 structure from 1.Sequence number and the mapping relations such as table 1 of TPC/SS
Shown in.
Table 1: sequence number and the mapping of TPC/SS order
Sequence number is according to formula: sequence number=2 × A+B (A=0,1,2；B=0,1) calculate.A is that the sequence selected is being divided
Relative sequence number in three sequences joined, when selecting reversion sequence, B is equal to 1, and otherwise B is equal to 0.It is used to refer to the sequence of TPC/SS
The power of row can arrange different from instruction ACK/NACK sequence.
HSPA+ is further evolution and the enhancing of HSPA (including HSDPA and HSUPA), and the main target of HSPA+ is to improve
Spectrum efficiency and peak rate, increase power system capacity and the number of users simultaneously supported, reduce State Transferring time delay, reduce terminal merit
Consumption.
After introducing HSPA+, add again the E-PUCH of a kind of scheduling, i.e. SPS (Semi Persitent Scheduling)
E-PUCH, this E-PUCH resource can be distributed by E-AGCH by Node B, reconfigure, and can pass through E-AGCH
Order regains.SPS E-PUCH has semi-continuous characteristic, and Node B can instruct distribute by an E-AGCH to be had
Fixed repetition period, the E-PUCH resource of infinite duration length.E-HICH signature sequence that SPS E-PUCH is used and non-
Being similar to of scheduling, is also a signature sequence group including 4 signature sequences, and is distributed by high-level signaling by RNC.SPS can
To use the E-HICH of scheduling, it is possible to use non-scheduled E-HICH.
In current standard, the E-PUCH and non-scheduled E-PUCH of scheduling can not use identical E-HICH, and this is just
The E-PUCH requiring network-side at least scheduling configures an E-HICH, configures an E-HICH for non-scheduled E-PUCH.
The E-HICH signature sequence that the E-PUCH of dynamic dispatching uses is determined by the code channel of its E-PUCH, and each user uses
One signature sequence, for loading ACK/NACK.
The E-HICH signature sequence that non-scheduled E-PUCH uses is distributed by high-level signaling by RNC, and RNC is each use
The UE of non-scheduled E-PUCH distributes a signature sequence group, and this signature sequence group includes 4 signature sequences, for feeding back this UE's
The ACK/NACK information of non-scheduled E-PUCH and TPC&SS command information, the signature sequence group on this E-HICH is this non-scheduled UE
Monopolized.
The signature sequence that the E-PUCH of SPS uses is similar with non-scheduled E-PUCH, is also to be divided by high-level signaling by RNC
Joining, RNC is that the UE of each use SPS distributes a signature sequence group, and this signature sequence group includes 4 signature sequences, for anti-
Presenting ACK/NACK information and the TPC&SS command information of the SPS E-PUCH of this UE, the signature sequence group on this E-HICH is for being somebody's turn to do
SPS UE is monopolized.
Which adds control channel overhead, bring the waste of code channel resource.The sequence and the E-PUCH dispatched signs
Row distributed by NodeB, non-scheduled and SPS E-PUCH signature sequence is distributed by RNC, multihead management bring complex management with
The problem that E-HICH signature sequence occupation mode is inefficient.It addition, MU-MIMO (Multi User-Multiple Input
Multiple Output) introduce after, the problem how signature sequence distributes, standard does not also have solution.

And be clear to.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the preferred embodiment of the method for the distribution signature sequence that the present invention proposes.
Fig. 2 is the schematic diagram of the preferred embodiment of the method for the MU-MIMO system distribution signature sequence that the present invention proposes.
Detailed description of the invention
As it is shown in figure 1, the preferred embodiment of the method for the distribution signature sequence of present invention proposition:
Step 101: all E-PUCH, i.e. includes that E-PUCH, non-scheduled E-PUCH, SPS E-PUCH of scheduling share E-
HICH；
Step 102: unification is distributed signature sequence by Node B according to code channel shared by the E-PUCH distributed for UE；
When the signature sequence quantity that code channel shared by the E-PUCH distributing to UE is corresponding is less than the quantity of required signature sequence,
The signature sequence of volume residual uses the signature sequence specified.
Specifically:
For the E-PUCH of scheduling, owing to it has only to 1 E-HICH signature sequence, therefore, Node B is the E-of scheduling
PUCH distributes code channel, E-PUCH code channel can obtain 1 E-HICH signature sequence accordingly, and this part is prior art, therefore
Will herein be described in detail；
For non-scheduled E-PUCH, SPS E-PUCH, owing to it needs 4 E-HICH signature sequences, so needing to examine
The assignment problem of worry signature sequence:
When the spreading factor that non-scheduled E-PUCH, SPS E-PUCH uses is less than or equal to 4, because 1 SF16 code
The corresponding signature sequence in road, the E-PUCH distributing to UE accounts at least 4 SF16 code channels, therefore can be by Node B according to E-PUCH
Shared code channel is that UE distributes 4 E-HICH signature sequences；
When the spreading factor that non-scheduled E-PUCH, SPS E-PUCH uses is equal to 8 (in due to TD-SCDMA system
Agreement K=8, also implies that the spreading factor of E-PUCH is 8 to the maximum):
When E-PUCH takies 2 time slots, the E-PUCH distributing to UE accounts for 4 SF16 code channels, therefore can be by Node B root
It is that UE distributes 4 E-HICH signature sequences according to the code channel shared by E-PUCH；
When E-PUCH takies 1 time slot, the E-PUCH distributing to UE accounts for 2 SF16 code channels, therefore can be by Node B root
Being that UE distributes 2 E-HICH signature sequences according to the code channel shared by E-PUCH, the signature sequence of volume residual then uses 2 specified
Signature sequence, thus obtain 4 E-HICH signature sequences.
Wherein, Node B be UE distribution signature sequence method particularly as follows: be r+i, i=0 by logical resource tag ID,
1 ..., n+1 the signature sequence of n distributes to UE, wherein,N+1 is the signature sequence that need to distribute
Quantity, t0For the last time slot in distribution time slot, q0For t0Minimum channel code number in time slot (1,2 ..., Q0), Q0For
t0The spread spectrum coefficient that time slot minimum channel code number uses.
The method of signature sequence is obtained at " 2GHz TD-SCDMA digital cellular by the logical resource tag ID of signature sequence
Mobile radio communication high speed uplink packet access (HSUPA) Uu interface physical layer technology requirement third portion: multiplexing and chnnel coding "
Described in, repeat the most one by one at this.
In the above-described embodiments, it is intended that the logical resource tag ID of signature sequence be descending time slot code channel corresponding to
, and the timeslot number of this descending time slot can be allocated to UE by RNC, the code channel of descending time slot and distribute to UE E-PUCH shared by
Code channel is identical.Wherein, the timeslot number of configuration is informed that the mode of UE can be by RNC: inform UE or by height by broadcast
Layer dedicated signaling informs UE.The corresponding table of the uplink and downlink timeslot being usually in broadcast in community, the mode of high-level signaling can
To be only certain descending time slot number, it is also possible to be uplink and downlink timeslot correspondence table.
Described descending time slot is the descending time slot corresponding to certain ascending time slot, or several ascending time slot with descending time
The descending time slot numbered in advance in the corresponding table of gap.Inform that UE time slot correspondence table is advantageous in that: when the code channel institute of UE oneself is right
When the signature sequence answered is not enough, and after the non-scheduled of UE or SPS E-PUCH resource are reconfigured to another time slot,
Still can know that it should use the signature sequence of which descending time slot, without being informed new upper by RNC by high-level signaling again
Descending time slot number corresponding to row time slot, this point is particularly important to SPS E-PUCH, because the resource reconfiguration of SPS E-PUCH
Carried out by Node B.Such as table 2:
It is of course also possible to do not utilize the logical resource tag ID that the code channel of descending time slot is corresponding, can be joined by network-side
Putting, use spreading factor is non-scheduled E-PUCH, SPS E-PUCH and the non-E-that other use spreading factors are 8 of 8
The configuration of PUCH up channel interval, in this manner it is possible to obtain the signature corresponding to non-E-PUCH code channel of same ascending time slot
Sequence.
But, when ascending time slot number is much larger than descending time slot number, may exist and there is no enough descending time slots
The problem of corresponding signature sequence, now can specify that non-scheduled E-PUCH, SPS E-PUCH uses less than or equal to 4
Spreading factor, or non-scheduled E-PUCH, SPS E-PUCH using spreading factor to be 8 is arranged in a time slot.Otherwise
Can only solve by the way of multi-configuration E-HICH.
After introducing the present invention, owing to the terminal of Release 8 does not the most appear on the market, for network-side, it is only necessary to consider compatibility
The problem of Release 7 terminal.The terminal of Release 7 thinks that the signature sequence of non-scheduled E-PUCH is configured by RNC, network-side
The terminal of Release 7 can be arranged on a carrier wave, the configuration on this carrier wave meets the regulation of Release 7 specification.
Release 8 and later terminal are arranged on another carrier wave, thus can guarantee that and support that the terminal of different qualities can
The most normally work.
The invention allows for the distribution method of signature sequence in MU-MIMO system.After MU-MIMO introduces, pairing
Multiple users use identical time slot, identical code channel are transmitted and receive, but use different Midamble Shift (instructions
Practice sequence offset code) to distinguish each user.Therefore signature sequence and the side of code channel resource binding in Release 7 can not be re-used
Formula obtains the signature sequence of UE, because after introducing MIMO, identical code channel resource can distribute to different UE in the same time.
The Midamble method of salary distribution in MU-MIMO is at SU-MIMO (Single User-Multiple Input Multiple
Output), on the basis of the Special Default Midamble Allocation introduced in, can expand each further
Code channel number corresponding to Midamble Shift, to carry more user at each time slot.Such as: the Midamble of community
Shift number K=8, having 8 Midamble Shift can use, and in the case of the SU-MIMO of double fluid, two stream is available
Midamble Shift is 1/3/5/7 and 2/4/6/8 respectively, it means that each Midamble Shift at least corresponding 4
The spread spectrum code of SF16.If the MU-MIMO of 4 weights, then further extend, often under the above-mentioned double fluid Midamble method of salary distribution
Corresponding 8 SF16 of individual Midamble Shift spread code, and 4 are flowed the Midamble Shift used can be 1/5,3/7,2/
6,4/8, it is also possible to be 1/3,5/7,2/4,6/8.Last which scheme of employing in pipe standards, it is clear and definite for having a bit, the most often
Individual user has exclusive Midamble Shift.This just brings foundation, often to the distribution simplification of signature sequence under MU-MIMO
Midamble Shift corresponding to the code channel of individual user is unique.
Therefore, as in figure 2 it is shown, in MU-MIMO system the distribution method of signature sequence include:
Step 201: the E-PUCH of scheduling, non-scheduled E-PUCH, SPS E-PUCH share E-HICH；
Step 202: by Node B according to the training sequence deviation code that code channel shared by E-PUCH is corresponding be each UE distribution signature
Sequence；
Needed for signature sequence quantity corresponding to described training sequence deviation code is less than each UE during the quantity of signature sequence, by
Node B is according to the signature sequence that the identical training sequence deviation code of descending time slot is each UE distribution volume residual.
Can specify that shared by signature sequence and E-PUCH that the relation of Midamble Shift corresponding to code channel is as follows:
First it is calculated logical resource tag ID r (r=according to the E-DCH resource distribution corresponding with HARQ response instruction
0,1,2,…,79).User's spendable logical resource tag ID is r.. (S-1).
Wherein:
t0For the last time slot in distribution time slot, i.e. maximum timeslot number (1,2 .., 5)；
M is t0Minimum channel code number in time slot (1,2 ..., Q0Midamble Shift corresponding to) (1,2,
...K)；
Q0For t0The spread spectrum coefficient that time slot minimum channel code number uses；
K is the Midamble Shift number of cell configuration.
Subsequent logic resource tag ID r is mapped to physical resource tag ID r ' on method and Release 7 in existing
Method identical, specifically refer to " 2GHz TD-SCDMA digital mobile cellular telecommunication net high speed uplink packet access (HSUPA)
Uu interface physical layer technology requirement third portion: multiplexing and chnnel coding ".
The signature sequence used for scheduling E-PUCH in MU-MIMO, owing to every UE has only to a signature sequence, presses
The most enough according to said method.
The signature sequence used for E-PUCH or SPS E-PUCH non-scheduled in MU-MIMO, owing to it needs 4
E-HICH signature sequence, so needing to consider the assignment problem of signature sequence.When training sequence deviation code number K in community is little
When equal to 4, at least corresponding 4 signature sequences of training sequence deviation code, the most enough.When the training sequence in community is inclined
When frameshit number K is more than 4 (K=8), when UE has more than one training sequence deviation code, can be by multiple training sequence deviation
Logical resource tag ID corresponding to Ma cascades to this UE use, such 2 and above training sequence deviation code at least corresponding 4
Individual signature sequence, the most enough.
When the logical resource tag ID corresponding to the training sequence deviation code of UE is not enough, by Node B according to time descending
The identical training sequence deviation code of gap is the signature sequence of UE distribution volume residual.Brief description each user only one of which is trained
Sequence offset code, the situation that signature sequence is not enough.
Consider in the case of 2 user MU-MIMO, the code word of corresponding 4 SF16 of each Midamble Shift.For making
With same two users (being expressed as user 1, user 2) spreading code of same time slot internal phase, according to formula 1, user 1 can use logic to provide
Source tag ID r0/r1, user 2 uses logical resource tag ID r2/r3, and the most each user needs 4 signature sequences to patrol
Collect resource tag ID.The 4 of certain descending time slot signature sequences now can be given user 1,2 use, the label of this descending time slot
Name sequential logic resource tag ID calculation formula to be used 1, such user 1,2 is respectively arranged with 4 signature sequences, meets and makes
Use demand.Or also can distribute different E-HICH to the user of pairing by the way of increasing E-HICH configuration, it is provided that
Enough E-HICH signature sequences.
The signature sequence that E-PUCH or SPS E-PUCH non-scheduled in MU-MIMO is used, it is considered to 4 users
In the case of MU-MIMO, the code word of corresponding 8 SF16 of each Midamble Shift.For using with time slot internal phase with spread spectrum
Four users (being expressed as user 1, user 2, and user 3, and user 4) of code, according to formula 1, user 1 can use logical resource label
ID r0/r1, user 2 uses logical resource tag ID r2/r3, user 3 to use logical resource tag ID r4/r5, user 4 to make
By logical resource tag ID r6/r7, the most each user needs 4 signature sequence logical resource tag ID.Solution party now
Method is similar to above-mentioned 2 user MU-MIMO.
The signature sequence that E-PUCH or SPS E-PUCH non-scheduled in MU-MIMO is used, it is considered to 8 users
In the case of MU-MIMO, the code word of corresponding 16 SF16 of each Midamble Shift.For using with time slot internal phase with spread spectrum
8 users (being expressed as user 1, user 2, and user 3, and user 4, and user 5, and user 6, and user 7, and user 8) of code, according to formula 1,
User 1 can use logical resource tag ID r0/r1, user 2 to use logical resource tag ID r2/r3, user 3 to use logic to provide
Source tag ID r4/r5, user 4 uses logical resource tag ID r6/r7, in like manner can obtain the logical resource mark of user 5/6/7/8
Signing ID, the most each user needs 4 signature sequence logical resource tag ID.Solution now is similar to above-mentioned 2 user MU-
MIMO。
