Description
Technical field
The present invention relates to communication technical field, particularly relate to a kind of carrier aggregation system feeds back response instruction
Method and device.
Background technology
3GPP (3rd Generation Partnership Project, 3rd Generation Partnership Project) LTE (Long Term
Evolution, Long Term Evolution) follow-up enhancing version be referred to as LTE-A (LTE-Advanced, enhancing
LTE), introducing many new technology in LTE-A, carrier aggregation (carrier aggregation) technology is done
For supporting that the key technology of more high bandwidth transmission is also introduced into wherein.
The ultimate principle of carrier aggregation is by the work that condensed together by the main carrier of two or more,
Thus meet higher bandwidth demand.In R10 (Release 10, version 10), TDD (Time Division
Duplexing, time division duplex) carrier aggregation be mainly used in Intra-band (in band) carrier aggregation, and
And current carrier set do not supports the TDD proportioning pattern that different sub-carrier configuration is different, therefore, R10
Define HARQ (Hybrid Automatic Repeat Request, hybrid automatic repeat-request) across
Carrier dispatching scheme, in the program, the response instruction for the data feedback of subcarrier carrying is unified in main load
Feeding back on ripple, this response instruction can include ACK (Acknowledge, correct response instructs) or NACK
(Not Acknowledged, incorrect response instructs).And at R11 (Release 11, version 11)
In, owing to introducing Inter-band (band is outer) carrier aggregation so that the TDD that different carrier is differently configured
Proportioning pattern is possibly realized.The benefit introducing mixing TDD proportioning pattern in inter-band carrier aggregation is
Self-evident, first, it makes same community different user become according to the differently configured proportioning of service needed
May；Secondly, by low-frequency range carrier wave configuration UL (Uplink, up) how TDD proportioning pattern,
To high band configuration DL (Downlink, descending) how TDD proportioning, can more effectively improve up
Cover and DL capacity；3rd, different frequency ranges need not be configured to identical TDD proportioning, it is ensured that
Compatibility with the frequency range that existing TDD configures.
At present, inter-band carrier aggregation supports that different TDD proportioning pattern is set up the project in R11, relates to
And TDD proportioning pattern mainly include TDD0～6 wherein proportioning pattern, different ratio pattern supports difference
Ratio of uplink subframe to downlink subframe.When TDD terminal support is received and dispatched simultaneously, multicarrier ACK/NACK feeds back,
Still continue to use single carrier scheduling scheme, namely the ACK/NACK feedback of all carrier waves is all enterprising at main carrier
OK.But this feedback scheme can exist in multi-carrier aggregation system bigger RTT (Round-Trip Time,
Round-trip delay), below in conjunction with case-study:
In single-carrier system, the ACK/NACK feedback of HARQ typically at 4ms and is carried out, the most later
Feedback position depends on that UL/DL subframe in-position and this subframe are by multiplexing (multiplexing)/bundling
The ACK/NACK number of (binding).Fig. 1 shows UL/DL HARQ under TDD1 proportioning pattern
The schematic diagram of ACK/NACK feedback, as it is shown in figure 1, in transmitting uplink data 1, upstream data exists
" up 1 (i.e. at the 1st sub-frame of uplink) " upper carrying, due to the 4th subframe after this " up 1 "
Can be as descending sub frame, therefore, the ACK/NACK that base station sends for this upstream data is " up
1 " the 4th sub-frame transmission after, the RTT=8ms of this transmission；In transmitting uplink data 2, up
Data are in " up 2 (i.e. at the 2nd sub-frame of uplink) " upper carrying, due to the after these " up 2 "
4 subframes be sub-frame of uplink, the 6th subframe just for descending sub frame, therefore, base station is for this upstream data
The ACK/NACK sent cannot be carried out in the 4th subframe after these " up 2 ", can only by the time be somebody's turn to do
The 6th subframe (this subframe is " descending 4 ", i.e. the 4th descending sub frame) feedback after " up 2 ",
The RTT=10ms of this transmission；In like manner, in downlink data transmission 3, terminal is for " descending 1 (i.e.
First descending sub frame) " the upper downlink data transmitted, the meeting the 7th up son after this " descending 1 "
Upper feeding back ACK/the NACK of frame (this subframe is " up 3 ", i.e. the 3rd sub-frame of uplink), this transmission
Corresponding RTT=11ms；In downlink data transmission 4, terminal is for " the S after " descending 1 "
Subframe " the upper downlink data sent, can the 6th sub-frame of uplink after this subframe (this subframe be " on
Row 3 ", i.e. the 3rd sub-frame of uplink) upper feeding back ACK/NACK, the RTT=10ms that this transmission is corresponding.
As it has been described above, in tdd mode, for the data of carrying on a certain sub-frame of uplink or descending sub frame
The ACK/NACK of feedback, can postpone because of the arrival time of next descending sub frame or sub-frame of uplink,
So that RTT time delay becomes relatively big, generally, for uplink ACK/NACK feedback, maximum
RTT is up to 14ms, feeds back for descending ACK/NACK, and maximum RTT is up to 17ms, and this will bring
Bigger data delay and delay variation.
In sum, there is the response instruction feedback problems not in time such as ACK/NACK in above-mentioned prior art,
Cause data transmission delay big, affect data transmission quality.

Detailed description of the invention
In order to provide the implementation of the promptness improving response instruction feedback, embodiments provide one
Plant method and the device feeding back response instruction in carrier set system, below in conjunction with Figure of description to this
Bright preferred embodiment illustrates, it will be appreciated that preferred embodiment described herein be merely to illustrate and
Explain the present invention, be not intended to limit the present invention.And the enforcement in the case of not conflicting, in the application
Feature in example and embodiment can be mutually combined.
Embodiment one
In multi-carrier scheme, main carrier can carry response instruction subframe do not arrive in the case of,
There may be the subframe that can carry this response instruction on subcarrier, for this kind of situation, the present invention is in order to more
Good land productivity running time-frequency resource, to improve the promptness of response instruction feedback, makes this response refer to by carrier shift
Order can be fed back in the subframe that can carry this response instruction of this subcarrier, thus reduces HARQ
RTT, to reduce data delay and delay variation.And on this basis, for part sub-frame of uplink number relatively
The carrier wave of few TDD proportioning pattern, the response feedback that can preferably reduce downlink data concentrates on these
Row subframe is fed back and is caused response and instruct congested.
The embodiment of the present invention one provides a kind of method feeding back response instruction in carrier set system, the method
The promptness of response instruction feedback (such as ACK/NACK) can be improved, thus reduce data transmission delay,
Improve data transmission quality.Specifically, the method relates generally at the skew of the base station multiple carrier waves to supporting
Reason process and data receiver's (base station or subscriber equipment) carry response to be fed back after receiving data and refer to
The determination process of the subframe of order, subsequent embodiment will be to this enforcement as a example by response instruction is as ACK/NACK
The processing procedure that example relates to is described in detail respectively.
One, the migration processing process of the base station multiple carrier waves to supporting
Base station carries out migration processing to the multiple carrier waves supported, is mainly in the multiple carrier waves to support at least
One carrier wave carries out time domain skew, the same subframe type included by multiple carrier shifts to each carrier wave supported
All subframes tend to being uniformly distributed in time domain, wherein, subframe type includes sub-frame of uplink and descending sub frame.
Specifically, owning of the same subframe type that multiple carrier shifts to each carrier wave supported is included by base station
Subframe tends to being uniformly distributed in time domain, can be realized by multiple offset manner, and Fig. 2 shows that base station will
All subframes of the same subframe type that multiple carrier shifts to each carrier wave supported includes tend in time domain
An equally distributed preferred implementation, as in figure 2 it is shown, mainly comprise the steps:
The multiple carrier waves supported are offset by step 201, base station according to different offset manner, obtain many
Carrier wave after group skew.
In this step 201, offset manner can pre-set, and can arrange multiple offset manner with logical
Cross this multiple offset manner and obtain the carrier wave after organizing skew more, and then select the migration result of optimum.Specifically
Ground, this offset manner can arrange what the number of carrier wave carrying out offseting in the plurality of carrier wave and/or carry out offset
Carrier wave needs the condition met, and further, on this basis, can arrange during each carrier shift permissible
The number of sub frames of skew, for example, it is possible to offset 1 when carrier shift is set respectively, 2,3......n subframe,
Wherein, the number of sub frames that n includes less than this carrier wave.Such as, this offset manner can include the load carrying out offseting
Ripple needs the condition met, such as the carrier wave that sub-frame of uplink number is more than the first setting value and the descending sub frame included
Number carries out the relative skew in time domain more than the carrier waves of the second setting value, will the bigger carrier wave of sub-frame of uplink number
The carrier wave bigger with descending sub frame number mutually offsets, with easily reach the subframe of same subframe type time
The purpose being evenly distributed on territory.Concrete offset manner can be arranged the most flexibly, the most another
One enumerates.
Step 202, for often organizing the carrier wave after skew, the same subframe type that each carrier wave is included all
Subframe arranges in time domain, and determines the variance yields at interval between each adjacent sub-frame.
In this step 202, after all subframes of the same subframe type included by each carrier wave arrange in time domain,
Determine the interval between the subframe of adjacent same subframe type successively, and calculate the variance at each interval
Value.
Step 203, selection have the carrier wave after one group of skew of minimum variance value as optimum migration result.
In this step 203, owing to variance yields can characterize the degree that is evenly distributed of same type of subframe, logical
Often variance the least explanation distribution is the most uniform, therefore, selects have the carrier wave after one group of skew of minimum variance and makees
The most uniform migration result of subframe distribution for same subframe type.
So far, all sons of the same subframe type that multiple carrier shifts to each carrier wave supported is included by base station
Frame tends to equally distributed flow process in time domain and terminates.By the flow process that Fig. 2 is corresponding, base station is determined by partially
The interval variance that after shifting, each carrier wave is distributed in time domain, will have the carrier wave after the skew of minimum variance, determine
All subframes of the same subframe type included for each carrier wave tend to equally distributed carrier wave in time domain.
In actual application, base station is when carrying out migration processing to the multiple carrier waves supported, owing to carrier wave wraps simultaneously
Include sub-frame of uplink and descending sub frame, need the subframe considering both subframe type totally to tend to equal in time domain
Even distribution, in a preferred implementation, in above-mentioned steps 202, can be for often organizing the load after skew
Ripple, distribution determines between variance yields and each contiguous downstream subframe at the interval between each neighboring upstream subframe
The variance yields at interval, in step 203, after can selecting one group of skew of difference minimum of two variances
Carrier wave is as optimum migration result.
Should be appreciated that the mode that above-mentioned base station carries out migration processing to the multiple carrier waves supported only realizes this
Bright a kind of preferred implementation, in actual application, various can make the same subframe after skew by skew
The subframe of type tends to equally distributed offset manner all within the application protection domain.
In order to be more fully understood that base station carries out the processing procedure of carrier shift, support below in conjunction with current carrier wave
TDD proportioning, the process relatively offset for carrier wave is specifically described.
In TDD proportioning, to TDD3～5, including descending sub frame number more, base station is contemplated that
The carrier wave of these TDD proportionings with configuration TDD0～2 or TDD6 is carried out relative skew, in order to fully drop
Low RTT time delay.
Fig. 3 shows that the carrier wave 1 of TDD1 proportioning carries out in time domain relative inclined with the carrier wave 2 of TDD2 proportioning
The schematic diagram moved, as it is shown on figure 3, can be by the carrier wave 1 of TDD1 proportioning relative to the load of TDD2 proportioning
Ripple 2 offsets 2 subframes in time domain, includes according to the migration result shown in Fig. 3, carrier wave 1 and carrier wave 2
All descending sub frames tend to being uniformly distributed in time domain, the most as shown in Figure 4, carrier wave 1 and carrier wave 2 wrap
The all sub-frame of uplink included tend to being uniformly distributed, the most as shown in Figure 5 in time domain.
Fig. 6 shows that the carrier wave 3 of TDD1 proportioning carries out in time domain relative inclined with the carrier wave 4 of TDD5 proportioning
The schematic diagram moved, as shown in Figure 6, can be by the carrier wave 3 of TDD1 proportioning relative to the load of TDD5 proportioning
Ripple 4 offsets 3 subframes in time domain, includes according to the migration result shown in Fig. 6, carrier wave 3 and carrier wave 4
All descending sub frames tend to being uniformly distributed in time domain, concrete as it is shown in fig. 7, carrier wave 3 and carrier wave 4 wrap
The all sub-frame of uplink included tend to being uniformly distributed, the most as shown in Figure 8 in time domain.
Base station is after using said process that the multiple carrier waves supported are carried out time domain skew, and base station can be in main load
Ripple is dispatched respectively with subcarrier, and respective PDCCH (Physical downlink control channel,
Physical Downlink Control Channel) above send UL grant (Uplink grant, uplink authorization) and DL assignment
(Downlink assignment, descending distribution).It addition, the feedback of ACK/NACK is also not limited to main
On carrier wave feed back, it is also possible to feed back on a subcarrier, such as, for downlink data feedback up
ACK/NACK is not limited to PUCCH (Physical uplink control channel, the thing of main carrier
Reason ascending control channel) on, but i.e. can be at PHICH (the Physical HARQ indicator of main carrier
Channel, Physical HARQ Indicator Channel) send on PUCCH, it is also possible at the PHICH of subcarrier
Send with on PUCCH.
Two, the process of the subframe of the response instruction carrying these data is determined after data receiver receives data
After base station carries out migration processing to the carrier wave supported, data receiver can be based on the carrier wave after this skew
Carrying out the feedback of response instruction, this response instruction can be not limited on main carrier feedback, it is also possible in pair
Feed back on carrier wave.Fig. 9 shows the schematic flow sheet feeding back response instruction in this carrier aggregation system, such as figure
Shown in 9, the process of this feedback response instruction, mainly comprise the steps:
Step 901, data receiver receive the data that present sub-frame carries.
In this step 901, data receiver can be that base station can also be for subscriber equipment, specifically, if number
Be base station according to recipient, then what this base station received is the upstream data of current sub-frame of uplink carrying, if data connect
Debit is subscriber equipment, then what this subscriber equipment received is the downlink data of current downlink subframe carrying.
Step 902, data receiver can hold from what the multiple carrier waves processed through base station drift included respectively
Carry in the subframe of response instruction of data, determine that the time interval with present sub-frame meets and set required
Individual subframe.
In this step 902, if data receiver is base station, then can carry the son of the response instruction of these data
Frame is descending sub frame, if data receiver is subscriber equipment, then can carry the son of the response instruction of these data
Frame is sub-frame of uplink.Further, if data receiver is subscriber equipment, before subscriber equipment performs this step,
Need to receive the offset information of the multiple carrier waves processed through base station drift that base station sends, with correctly basis
This offset information is determined that the time interval with present sub-frame meets and is set the subframe required.
Step 903, data receiver carry the response for this data feedback in the subframe determined and instruct.
In this step 903, if data receiver is base station, then base station carries on the descending sub frame determined
The response instruction fed back for this upstream data, if data receiver is subscriber equipment, then subscriber equipment is really
Carrying the response instruction fed back for this downlink data on the sub-frame of uplink made, wherein, response instruction is permissible
For ACK/NACK.
So far, the flow process feeding back response instruction in this carrier aggregation system terminates.By the flow process that Fig. 9 is corresponding,
Data receiver is after the data receiving present sub-frame carrying, from the multiple carrier waves processed through base station drift
In the subframe of response instruction that can carry these data included respectively, determine and between the time of present sub-frame
Every the satisfied subframe setting and requiring, and it is anti-to carry the data for receiving in the described subframe determined
The response instruction of feedback.According to this technical scheme, the response instruction for the data feedback received can passed through
Carry on multiple carrier waves that base station drift processes, compared with prior art, improve response instruction feedback and
Shi Xing, thus reduce data transmission delay, improve data transmission quality.
In the step 902 that Fig. 9 correspondence flow process includes, wrap respectively from the multiple carrier waves processed through base station drift
In the subframe of response instruction that can carry described data included, determine that the time interval with present sub-frame is full
Foot sets the subframe required, it may be preferred to ground is by any one mode in the following two kinds mode:
Mode one
From the multiple carrier waves processed through base station drift include respectively can carry these data response instruction,
And with the time interval of present sub-frame more than in the subframe processing the time of these data, determine and present sub-frame
The minimum subframe of time interval.
Mode two
From the multiple carrier waves processed through base station drift include respectively can carry these data response instruction,
The load capacity of the carrying response instruction time interval less than setting threshold value and with present sub-frame is more than these data
In the subframe of process time, determine and the subframe being spaced minimum of present sub-frame.
In aforesaid way one and mode two, the process time index of data receives these data to this according to recipient
The processing procedure of data.
After subscriber equipment receives the downlink data of main carrier or subcarrier, owing to subscriber equipment receives data
After, these data to be carried out data decoding etc. and process, need a period of time could feeding back ACK/NACK,
Therefore, subscriber equipment after the descending sub frame carrying these data n-th (relative user equipment is to these data
The process time) individual subframe starts, it is anti-that the sub-frame of uplink at main carrier or subcarrier carries out ACK/NACK
Feedback, the determination method of concrete feedback position sees aforesaid way one or mode two.Specifically, when
When ACK/NACK feedback and data are on different carrier, PUCCH resource used can be configured by base station
Determining, the configuration process of this PUCCH resource is particularly as follows: reserve a part respectively on each carrier wave
PUCCH resource is specially for the ACK/NACK feedback of the downlink data on other carrier wave, each subscriber equipment
The PUCCH resource that can use in this region is configured by RRC signaling by base station.Due to possible many
Individual subscriber equipment is assigned identical PUCCH resource, and therefore, base station should be noted that when scheduling and avoids
Occur that the subscriber equipment that identical PUCCH resource is assigned enters at the same sub-frame of uplink of same carrier wave
Row ACK/NACK feeds back.In like manner, after base station receives the upstream data of main carrier or subcarrier, equally
The n-th subframe (respective base station process time to these data) after the sub-frame of uplink carrying this upstream data
Starting, the descending sub frame on main carrier/subcarrier carries out ACK/NACK feedback, works as ACK/NACK
When feedback and data are on different carrier, PHICH resource used is determined by base station configuration, concrete configuration
Process is identical with the configuration process of above-mentioned PUCCH resource, and what difference was to configure herein is PHICH money
Source.
According to the flow process that Fig. 9 is corresponding, after base station receives ACK/NACK feedback, can be again to this
HARQ process is scheduling；After subscriber equipment receives ACK/NACK feedback, can be again at this
HARQ process carries out retransmitting or new biography.
