Detailed description of the invention
In the present invention, first define the distribution of two kinds of ascending resource and conflict:
Type I: reconfigured the sub-frame of uplink (Physical of changed radio frames by TDD
Uplink Shared CHanneel, PUSCH) ascending resource distribution be positioned at previous change before
The sub-frame of uplink of frame, as shown in Figure 1.The sub-frame of uplink of the frame before this previous change is (i.e.
No. #8 and #9 sub-frame of uplink) it is referred to as subframe of conflicting.Specifically, according to the second radio frames
Uplink-downlink configuration mode 4, No. #2 of the second radio frames is divided with the ascending resource of #3 sub-frame of uplink
Be coordinated in No. #8 of the first radio frames and #9 sub-frame of uplink, No. #8 of this first radio frames and
#9 sub-frame of uplink is referred to as subframe of conflicting.No. #2 of second radio frames and #3 sub-frame of uplink claim
For subframe to be dispatched.
Type II: reconfigured the sub-frame of uplink (PUSCH) of changed radio frames by TDD
Ascending resource distribution be positioned at the descending sub frame of the frame before previous change, but it is not one
The descending sub frame of the individual actual parameter having in table two, as shown in Figure 2.Such as, on using
The #9 work song frame corresponding to first wireless sub-frame of downstream arrangements mode 2 is descending sub frame, but
As shown in Table 2, this descending sub frame is not defined for transmitting ascending resource configuration information.The
The #3 sub-frame of uplink of two radio frames is referred to as subframe to be dispatched.
The multiple different combination that dynamic TDD up-downgoing is reconfigured, in order to simplify description,
The present invention provides two kinds of solutions to process timing conflict.Set user terminal and base station is all known
TDD configuration before and after reconfiguring dawn, when the ascending resource shown in figure 1 above is joined
Putting conflict when occurring, having a following solution:
Scheme 1:
As shown in (b) part in Fig. 2, when, after first frame, tdd frame configures from joining
Set to 0 change into configuration 4 time, according to scheme 1, user terminal is not listening in this conflict subframe
Control information, and in this subframe to be dispatched, keep silent status.
Specifically, as shown in (b) part in Fig. 2, join in advance in base station and user terminal
If put generation ascending resource distribution conflict, user uses the processing mode mourned in silence.
The up-downgoing that then first user terminal receives from base station reconfigures triggering command, is used for leading to
Know that user terminal uplink-downlink configuration mode changes, from (the configuration of the first uplink-downlink configuration mode
Mode 2) change into the second uplink-downlink configuration mode (configuration mode 4).
Then, user terminal does not carry out monitoring conflict subframe, that is, user terminal is not first
No. #8 of radio frames and #9 work song frame intercept channel, thus save the power supply of user terminal,
Save energy, and, user terminal actively abandons treating dispatching uplink subframe, namely the second nothing
#2 and #3 work song frame in line frame, namely user terminal is not at this subframe #2 to be scheduled and #3
On carry out uplink.
Scheme 2:
The program devises new mapping mode and conflicts to process ascending resource distribution, below, point
Do not remap mode 1,2 and 3 according to first to discuss.
First remaps mode 1:
Under this is treated that the ascending resource distribution corresponding to dispatching uplink subframe is remapped to effectively
In row subframe, this effective descending sub frame is the closest descending sub frame of subframe that conflicts with this, and
This effective descending sub frame can be used for carrying ascending resource distribution
Specifically, when sending out owing to TDD up-downgoing reconfigures the ascending resource distribution conflict caused
Time raw, ascending resource assignment signalling is moved forward on nearest suitable descending sub frame, and
This subframe has the actual parameter of table two.Such as, the ascending resource distribution sequential of conflict is positioned at and changes
In subframe n' of the configuration before change, new mapping position is n ", it has in table two effective k also
And meet n "-n' minimum.If n "-n' is negative value, then virtual value should be equal to n "-n'+10.
The advantage of which is that it can reduce and is reconfigured the upload control letter caused by TDD configuration
The transmission delay of order, and it needs certain complexity.
Illustrate as a example by (a) part in Fig. 3 and (c) part in Fig. 3.This is heavy
In new mappings mode, distribute institute by the ascending resource of #2 and the #3 work song frame in the second radio frames
Conflict subframe #8 being positioned at and #9 move forward to nearest descending sub frame #6, and this first nothing respectively
#6 work song frame in line frame can be used for carrying the up money of #2 and the #3 work song frame of the second radio frames
Source is distributed, namely this #6 work song frame has effective k value.
First remaps mode 2:
Under this is treated that the ascending resource distribution corresponding to dispatching uplink subframe is remapped to effectively
In row subframe, this effective descending sub frame is to treat at least 4 transmission of distance of dispatching uplink subframe with this
The descending sub frame of time interval (Transport Time Interval, TTI), and this is the most descending
Subframe can be used for carrying ascending resource distribution.
Specifically, when sending out owing to TDD up-downgoing reconfigures the ascending resource distribution conflict caused
Time raw, ascending resource assignment signalling is re-mapped to nearest suitable descending sub frame, this son
Frame shifts to an earlier date at least 4 TTI and the effective ginseng having in upper table than sub-frame of uplink to be scheduled
Number.
Illustrate as a example by (a) part in Fig. 3 and (c) part in Fig. 3.This is heavy
In new mappings mode, distribute weight by the ascending resource of #2 and the #3 work song frame in the second radio frames
New mappings to the descending sub frame before at least 4 TTI of #2 and the #3 work song frame in radio frames,
And this descending sub frame can be used for carrying the ascending resource of #2 and the #3 work song frame of the second radio frames and divides
Joining, identical with mode 1, corresponding descending sub frame is also the #6 descending sub frame in the first radio frames.
First remaps mode 3:
At least one is treated, and the distribution of the ascending resource corresponding to dispatching uplink subframe is remapped to
Effectively on descending sub frame, this effective descending sub frame is this punching in this first uplink-downlink configuration mode
The descending sub frame corresponding to ascending resource distribution of prominent subframe
When ascending resource distribution conflict occurs, it is used primarily for sending the subframe of ascending resource distribution
It is a sub-frame of uplink, is designated as the sub-frame of uplink that conflicts.Then, initial ascending resource divides
Joining signaling and moved to a descending sub frame further along, this descending sub frame have sent in conflict
The ascending control information of row subframe.The sequential of order conflict sub-frame of uplink is positioned at the configuration before change
In subframe n', new mapping position is n ", wherein k'=n "-n' be for change before configuration
Subframe n " actual parameter in table two.The advantage of the program is to need not when defined
Between define new sequential relationship outside table, but upstream control signaling will stand two link maps,
This can cause certain control to postpone.
Illustrate as a example by (a) part in Fig. 3 and (d) part in Fig. 3.This is again
In mapping mode, the ascending resource of No. #2 of the second radio frames and #3 work song frame distributes by indirectly
In the control subframe of ground forward link to No. #8 of the first radio frames and No. #9 conflict sub-frame of uplink,
The #1 work song frame of the i.e. first radio frames.
For conflict type I, all of scheme can be suitable for.But, for type 2, only
Have in scheme 1 and scheme 2 first remap mode 1 and first remap mode 2 can
To be suitable for, first to remap mode 3 be not to be suitable for.
For scheme 2, taking it by and large, the distribution of each ascending resource is all adjusted in a PDCCH
Degree.But, there is also such situation: PDCCH have relatively low schedule by probability mode two or
More ascending resources distribute.It is true that relate to uplink-downlink configuration in specification TS 36.213
The ascending resource distribution of 0, that is, because descending sub frame is less than up son in uplink-downlink configuration 0
Frame, therefore, is likely to be of the distribution of multiple ascending resource, this situation in a sub-frame of uplink
It is entirely soluble.
In this part, the example of the application of the mapping scheme made new advances in conjunction with Fig. 5, will be given, with
The problem solving the ascending resource distribution conflict of PUSCH as shown in Figure 1.
Fig. 5 shows the system approach flow chart of a specific embodiment according to the present invention.
Base station and user terminal know the tool when there is ascending resource distribution conflict before a communication
Body ground uses that one to remap mode.
First, as it is shown in figure 5, in step s 50, base station judges whether to need in the first nothing
Line frame uses the first uplink-downlink configuration mode, in second radio frames adjacent with this first radio frames
Use the second uplink-downlink configuration mode, wherein, this second radio frames treats dispatching uplink subframe
Corresponding ascending resource distribution is positioned in the conflict subframe of this first radio frames, this conflict subframe
It is sub-frame of uplink, or this conflict subframe is to be not useable for carrying the son of ascending resource configuration information
During frame.
Then, in step s 51, when needed, base station uses first to remap mode,
This is treated that the ascending resource distribution corresponding to dispatching uplink subframe is reflected again by this mode that remaps
Being mapped on this effective descending sub frame treated before dispatching uplink subframe, this effective descending sub frame can be used
In carrying ascending resource distribution.
Such as, then base station is remapped mode according to use, if using first side of remapping
Formula 1, then base station correspondingly adjusts the position of the ascending resource distribution that conflict subframe is carried, as
Shown in (c) part in subgraph 3, ascending resource distribution is moved to the #6 of first frame
On work song frame.
If base station uses first to remap mode 2, then obtain remapping mode 1 phase with first
The same mode that remaps, ascending resource distribution is moved on the #6 work song frame of first frame.
If base station uses first to remap mode 3: as shown in (d) part in Fig. 3, the
The upstream control signaling of No. #2 of two subframes and #3 work song frame is by indirectly to being front linked to the
In the control subframe of No. #8 of one frame and No. #9 conflict sub-frame of uplink, i.e. the #1 of first frame
Work song frame.
Then, in step S52, base station uses broadcast or radio resource control signaling
Send to user terminal and reconfigure message, use the second up-downgoing to join for indicating user terminal
Put mode.
User terminal is known uses the first uplink-downlink configuration mode in the first radio frames.Then, exist
In step S53, user terminal receives and reconfigures message from base station, and this reconfigures and disappears
Breath uses the second up-downgoing to join for instruction in the second radio frames adjacent with this first radio frames
Put mode, wherein, this second radio frames treats the ascending resource corresponding to dispatching uplink subframe
Distribution is positioned in the conflict subframe of this first radio frames, and this conflict subframe is sub-frame of uplink, or
This conflict subframe is the subframe being not useable for carrying ascending resource configuration information；
Then, in step S54, user terminal remaps mode according to first, determines this
Treating the ascending resource distribution corresponding to dispatching uplink subframe, wherein, this effective descending sub frame can be used
In carrying ascending resource distribution；
Then, in step S55, according to the ascending resource distribution being successfully decoded, wait to adjust at this
Uplink is carried out on degree sub-frame of uplink.
It is clear to see that the first of scheme 2 remaps mode 1 and first and remaps mode 2 and have
There is more complicated mapping, but achieve shorter control and postpone, and the first replay of scheme 2
Penetrate mode 3 to have and simpler map but stand longer control and postpone.
Sum it up, compared with scheme 1, scheme 2 gives more positive mode and processes
Map conflict, and the performance that this scheme reconfigures for ensureing dynamic TDD up-downgoing increases
It is the most necessary for benefit.
For dynamic TDD uplink-downlink configuration, PDSCH (Physical Downlink Shared
Channel) HARQ (Hybrid Automatic Repeat reQuest) response message time
Sequence also can meet with collision problem.The HARQ response message of this PDSCH (include ACK and
NACK) sequential is defined in the table 10.1-1 of specification TS 36.213, in this specification
Shown in table four.Digital k in table four represents that current sub-frame of uplink n is sub for feedback the n-th-k
The PDSCH data of frame.
Table four: Downlink association set indexK:{k0,k1,…kM-1}for TDD(TS 36.213Table 10.1-1)
As shown in Figure 4, when configuring 3 and being configured to tdd frame structure, (a) in Fig. 4
Partially illustrate the ACK/NACK sequential of PDSCH according to upper table.(b) in the diagram
In part, owing to the downlink business in the second radio frames increases, TDD configuration is changed to
Downstream arrangements 2.Visible, two of some PDSCH subframe in the first radio frames
ACK/NACK should feed back in the second radio frames No. #3 and #4 work song frame, but this #3
Number and the link direction of #4 work song frame be descending, therefore these ACK/NACK cannot be by correctly
Decoding.Crossing after date, re-transmission is triggered, and this will cause longer transmission delay, even leads
Cause serious bag/file to lose.
In order to solve the conflict of this type, the present invention proposes should for PDSCH HARQ
Answer the new scheme of message.
The descending sub frame being primarily upon in the frame before previous change, their ACK/NACK
Timing conflict will occur.In order to solve this conflict, propose one and substitute uplink-downlink configuration side
Formula X, and make the PDSCH HARQ sequential of paid close attention to descending sub frame meet configuration X.Choosing
The rule selecting X is as follows:
Table five
Illustrate as a example by Fig. 4.The uplink-downlink configuration of the first radio frames is Configuration
3, the uplink-downlink configuration of the second radio frames is Configuration 2, table look-up five obtain substitute
Uplink-downlink configuration X is Configuration 5.It is meant that can be according to Configuration 5
The sequential relationship of PDSCH HARQ, the corresponding PDSCH's that feedback conflict occurs
ACK/NACK, such as (c) part in Fig. 4.
Specifically, in using uplink-downlink configuration mode 5, #2 subframe is for sending for this son
The HARQ of the PDSCH of 13,12,9,8,7,5,4,11,6 subframes before frame
Response message.
It can be seen that replacement uplink-downlink configuration mode may not be unique from table five.In bracket
Uplink-downlink configuration can be as the selection of low priority.
Fig. 6 shows system approach flow chart according to an embodiment of the invention.
First, comprising the following steps: first, in step S60, base station judges whether needs
The first uplink-downlink configuration mode is used, adjacent with this first radio frames in the first radio frames
Two radio frames use the second uplink-downlink configuration mode, and wherein, being used in this first radio frames passes
Target mixing request automatically corresponding to the descending sub frame of the data of defeated Physical Downlink Shared Channel
Retransmitting response message to be positioned in the conflict subframe of this second radio frames, this conflict subframe is descending son
Frame.
Then, in step S61, when needed, base station uses broadcast or wireless money
Source controls signaling and sends to user terminal and reconfigure message, uses for indicating user terminal
Two uplink-downlink configuration modes；
Then, in step S62, user terminal receives and reconfigures message from base station,
This reconfigures message and uses in the second radio frames adjacent with this first radio frames for instruction
Second uplink-downlink configuration mode, wherein, descending common for transmitting physical in this first radio frames
Target mixing automatic repeat request response message corresponding to the descending sub frame of the data enjoying channel
Being positioned in the conflict subframe of this second radio frames, this conflict subframe is descending sub frame；
Then, in step S63, user terminal remaps mode according to second, chooses and replaces
For uplink-downlink configuration mode.This step specific implementation sees table five.
Such as, user terminal is according to the first uplink-downlink configuration mode and the second uplink-downlink configuration mode
Syntagmatic, choose and sub-frame of uplink only comprise this first sub-frame of uplink and this second up son
The uplink-downlink configuration mode of all or part of total sub-frame of uplink of frame is upper and lower as this replacement
Row configuration.Such as, uplink-downlink configuration mode 1 and uplink-downlink configuration mode 3 is whole total
Sub-frame of uplink is #2 and #3.Then substitute uplink-downlink configuration mode can select sub-frame of uplink comprises
The uplink-downlink configuration mode 4 of the most total sub-frame of uplink #2 and #3, it is also possible to select up son
Frame comprises the uplink-downlink configuration mode 5 of the total sub-frame of uplink #2 of part.Otherwise, such as,
Uplink-downlink configuration mode 2 cannot function as substituting uplink-downlink configuration.Because uplink-downlink configuration mode 2
Also include non-uplink-downlink configuration mode 1 and the common sub-frame of uplink of uplink-downlink configuration mode 3.
Then, in step S64, user terminal uses in this replacement uplink-downlink configuration mode
The sub-frame of uplink the most common with this first uplink-downlink configuration mode and the second uplink-downlink configuration mode
In at least one substitute subframe send to base station this target mixing automatic repeat request response disappear
Breath.Such as, there may be and the first uplink-downlink configuration mode in substituting uplink-downlink configuration mode
The multiple sub-frame of uplink all total with the second uplink-downlink configuration mode, when this alternative is selected
After, the multiple up son that this is all total with first, second uplink-downlink configuration mode may be used
One or more replacement sub-frame of uplink in frame send target mixing automatic repeat request response and disappear
Breath.
Then, in step S65, remapping mode according to second in base station, chooses in replacement
Downstream arrangements mode.
