Description
Technical field
The present invention relates to wireless communication field, more particularly to a kind of uplink resource allocating method and device.
Background technology
With the high speed development of the communication technology, the various terminals of user, such as：The smart machines such as mobile phone, tablet personal computer all may be used
To carry out the transmission of data message by communication network.And with the construction of 5G communication networks, it is desirable to communication base station and user
There can be higher data transmission bauds between terminal, to support the demand of following substantial amounts of data transfer.
Communication base station to user terminal send control information or transmission data be referred to as data downstream transmission, user terminal to
Communication base station sends control information or transmission data are referred to as data upstream transmission.Uplink and downlink transfer can when
Between on be divided into TTI (Transmission Time Interval, Transmission Time Interval) one by one, a TTI is 1ms,
The scheduler of communication base station can call the frequency domain resource on the communication frequency domain in the 1ms in a TTI, for sending control
Information or transmission data.The resource for being completely used for data transfer that can be dispatched in a TTI is properly termed as a subframe, one
The length of individual subframe is also that data and control information can be included in 1ms, the frame structure of subframe, for example, communication base station can be
Contain PDCCH (Physical Downlink Control Channel, physical down control in n-th of subframe in downlink transfer
Channel processed), PDCCH is used to carry scheduling and other control information, can be individual in the n-th+k of uplink with scheduling user terminal
Subframe sends PUSCH (Physical Uplink Shared Channel, physical uplink Data Shared Channel), and k typically takes 4.
PUSCH is used to send control information or transmission data to communication base station.
In order to improve the data transmission bauds between communication base station and user terminal, original TTI in a communication network
A kind of basis of frame, it is proposed that sTTI (short-Transmission Time Interval, the Transmission Time Interval of shortening)
Frame.The resource that sTTI takes in time domain is less than TTI, for example, can be 0.5ms, can have two sTTI in a TTI.Accordingly
, in uplink or downlink transfer, sPDCCH (short-Physical Downlink can be contained in sTTI
Control Channel, low time delay Physical Downlink Control Channel) or sPUSCH (short-Physical Uplink Shared
Channel, low time delay physical uplink Data Shared Channel), all kinds of control information and data for transmitting low time delay.In reality
In, TTI and sTTI can be used simultaneously, in a sub- frame in, by the scheduling of communication base station, make TTI and sTTI
The resource of used frequency domain is different, i.e., one sub- frame in, and the data that TTI is transmitted use the part in whole frequency ranges,
And the data transmitted in sTTI use the frequency range of another part.
Referring to Fig. 1, ordinate is frequency domain in Fig. 1, and abscissa is time domain, and a TTI length subframes 101 are divided into two
Contained sPUSCH occupies the frequency domain resource of half in sTTI, and two sTTI；Subframe 102, then be not divided into
STTI, its frequency domain resource can be completely shared by PUSCH contained in TTI.
Based on These characteristics, now in the art, when communication network can use TTI and sTTI simultaneously, user terminal exists
During uplink, the problem of frequency domain resource conflicts is likely to result in.For example,
In subframe n, communication base station sends a scheduling control information to the first user terminal, makes the first user terminal in subframe
N+4 sends PUSCH, and now whole available frequency bands on subframe n+4 frequency domains are distributed to the first user terminal by base station；
In next subframe n+1, communication base station receives the control information of second user terminal transmission, the control information
Communication base station is notified, second user terminal needs the sPUSCH to communication base station uplink low time delay, so communication base station meeting
In subframe n+2, the schedule information of low time delay is sent to second user terminal, due to being the schedule information of low time delay, is used
STTI is as Transmission Time Interval, when communication base station scheduling second user terminal is also sent in subframe n+4 to communication base station
During sPUSCH.Now corresponding subframe n+4 all upstream band resources are already allocated to the first user terminal.Due to TTI's
Scheduling decision of the scheduling decision prior to sTTI, TTI frequency domain resource distribution may block sTTI frequency domain resource distribution, so that
Cause uplink frequency domain resources distribution conflict.

Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation is described, it is clear that described embodiment is only a part of embodiment of the invention, rather than whole embodiments.It is based on
Embodiment in the present invention, it is every other that those of ordinary skill in the art are obtained under the premise of creative work is not made
Embodiment, belongs to the scope of protection of the invention.
Referring to Fig. 2, Fig. 2 is the uplink resource allocating method flow provided in an embodiment of the present invention applied to communication base station
Figure, including：
Step 201, as the up shared data channel sPUSCH of communication base station scheduling low time delay, communication base station judges
Frequency domain resource where sPUSCH, if scheduled up shared data channel PUSCH is accounted for before the sPUSCH that has been scheduled
With.
When carrying out the transmission communication of data, communication base station can send to contain to each user terminal to be used to dispatch user
Terminal sends the control information of various information, for example, PDCCH or sPDCCH etc..When user terminal receives the control information
When, it is possible to according to the instruction of the control information, corresponding data and control information are uploaded to communication base station.User terminal is to logical
The data and control information that letter base station is uploaded can be carried by sPUSCH or PUSCH.Communication base station by above-mentioned mode,
The scheduling to sPUSCH or PUSCH can be realized.
When communication base station scheduling user terminal is in a sTTI, and sPUSCH is sent to communication base station, communication base station can
First to judge the frequency domain resource on the sTTI where scheduled sPUSCH, if shared by PUSCH scheduled before
With.
For example, with reference to Fig. 3, in subframe 301 in Fig. 3, communication base station uses downlink transfer, sends and controls to each user terminal
Information processed, e.g., the PDCCH containing scheduling control information use uplink, in subframe 301 for dispatching the first user terminal
During the 4th subframe 305 afterwards, PUSCH is sent to communication base station, and the whole frequency domain resource of subframe 305 is distributed on the
One user terminal sends PUSCH；
In subframe 303, communication base uses downlink transfer, and control information is sent to each user terminal, and scheduling second is used
Family terminal uses uplink, also in subframe 305, and sPUSCH is sent to communication base station.
Now, communication base station is when dispatching sPUSCH, it can be determined that go out, in the subframe 305 where scheduled sPUSCH
Frequency domain resource, scheduled PUSCH, the i.e. frequency domain resource of the subframe 305 be before being allocated for sending before
Through being distributed on the first user terminal, for sending PUSCH.
Specifically, communication base station can judge scheduled sPUSCH institutes using the modes such as record, or daily record are inquired about
Frequency domain resource, if by institute before scheduling PUSCH shared by.
Step 202, if so, then communication base station generates conflicted resource indicating downlink control information DCI, conflicted resource is indicated
DCI include sPUSCH the upper occupancy of frequency domain resource information, for indicating user terminal be directed to the PUSCH, PUSCH with
SPUSCH is punched the equitant position on frequency domain.
When communication base station is judged, the frequency domain resource where scheduled sPUSCH, institute before the sPUSCH that has been scheduled
When the PUSCH of scheduling takes, communication base station can generate a conflicted resource and indicate DCI.
DCI can be carried by PDCCH, when communication base station to user terminal transmitted by Downlink Control Information, can include
Up-downgoing resource allocation, HARQ (Hybrid Automatic Repeat reQuest, hybrid automatic repeat-request) information, work(
Rate control etc..
When conflicted resource indicates that DCI is used exclusively for solving user terminal to communication base station transmission sPUSCH or PUSCH, on
Row resource allocation produces Downlink Control Information during conflict.
In conflicted resource indicates DCI, resource informations of one or more sPUSCH in the upper occupancy of frequency domain can be included,
Send specific frequency band range used in the sPUSCH., can be with after user terminal, which receives the conflicted resource, indicates DCI
The resource information of sPUSCH in DCI in the upper occupancy of frequency domain is indicated according to conflicted resource, to transmitted, and with this
The PUSCH that in uplink frequency domain resource conflict occurs for sPUSCH is punched so that the PUSCH transmitted by user terminal is not
Take again with the equitant frequency domain resources of sPUSCH, so as to avoid during uplink, sPUSCH is provided with PUSCH frequency domains
Source is to the problem of conflict.
Transmitted data or control information are punched, are to remove part to transmitted data or control information to use
In the data or information of scrambling, the integrality of the data to be sent or control information can't be destroyed, belongs to prior art,
This is repeated no more.In embodiments of the present invention, user terminal is punched to transmitted PUSCH, can sending
During PUSCH, the frequency domain resource being perforated is not used.And then avoid PUSCH and sPUSCH frequency domain resource overlap and
Conflict.
Step 303, communication base station sends the conflicted resource to user terminal and indicates DCI.
Communication base station is generated after conflicted resource instruction DCI, it is possible to is sent the conflicted resource to user terminal and is indicated
DCI.Communication base station can be sent using the form of the broadcast user terminal all into the communication base station institute coverage to be contained
The conflicted resource indicates DCI information.User terminal can obtain communication base station transmitted information, and therefrom obtain the conflict
Resource indicate DCI and other be used for dispatch control information of the user terminal etc..
User terminal is obtained after conflicted resource instruction DCI, it can be determined that whether have PUSCH to be sent, if
DCI is indicated without the conflicted resource that can then abandon receiving, without subsequent treatment；
If there is PUSCH to be sent, then judge conflicted resource indicate one or more of DCI sPUSCH in frequency
The resource information of the upper occupancy in domain, if there is overlapping part on frequency domain with PUSCH to be sent, if without overlapping
Part, then can abandon the conflicted resource and indicate DCI, without subsequent treatment；
When conflicted resource indicates the resource information and PUSCH to be sent of the upper occupancy in frequency domain of the sPUSCH in DCI
When having overlapping part on frequency domain, user terminal can be directed to the PUSCH to be sent, to the PUSCH and sPUSCH weights
Punched at the position of folded frequency domain, user terminal is no longer to take and the equitant parts of sPUSCH sending the PUSCH
Frequency range, it is to avoid during uplink PUSCH with sPUSCH conflicting in frequency domain resource.
In embodiments of the present invention, when communication base station dispatches sPUSCH, the frequency domain where scheduled sPUSCH is judged
Resource, if scheduled PUSCH takes before the sPUSCH that has been scheduled；If the frequency domain resource is by scheduled before
PUSCH take, then communication base station generation conflicted resource indicating downlink control information DCI, and sends the conflict to user terminal
Resource indicates DCI.User terminal indicates that the sPUSCH contained in DCI believes in the resource of the upper occupancy of frequency domain according to the conflicted resource
Breath, for PUSCH, in PUSCH and sPUSCH, equitant position is punched on frequency domain, is caused by punching transmitted
PUSCH no longer take with the equitant band segments of sPUSCH, so as to avoid user terminal uplink time-frequency domain provide
The problem of source conflicts.
Optionally, in uplink resource allocating method provided in an embodiment of the present invention, conflicted resource indicates that DCI includes in advance
If public RNTI (Radio Network Tempory Identity, Radio Network Temporary Identifier), presetting public RNTI is used for
Cyclic check code CRC in DCI, which is scrambled, to be indicated to conflicted resource.
In actual applications, with multiple PUSCH frequency domain resource may occur for the sPUSCH scheduled in communication base station simultaneously
Conflict, and multiple PUSCH are transmitted by different user terminals.For example, with reference to Fig. 4, Fig. 4 represents a TTI subframe, should
TTI subframes can be divided into two sTTI, and wherein ordinate represents frequency domain, and abscissa represents time domain, and region 401 is the first use
Family terminal the first PUSCH to be sent, region 402 is second user terminal the 2nd PUSCH to be sent, and region 403 is the 3rd
User terminal sPUSCH to be sent, it is seen that region 403, while occupying the portion in region 401 and region 402, i.e.,
SPUSCH there occurs overlapping with the first PUSCH and the 2nd PUSCH frequency domain.
In this case, if for each transmission PUSCH user terminal, individually producing a conflicted resource and referring to
Show DCI, then can greatly increase the portfolio of communication base station.
DCI is indicated in order to generate unified conflicted resource for multiple different user terminals, can be in conflicted resource
Indicate in DCI using default public RNTI.It is public user's mark to preset public RNTI, by the public identifier, can be with
The conflicted resource that communication base station is generated indicates that DCI is recognized by whole user terminals of this cell.And make
Obtain each user terminal and may determine that the DCI indicates DCI for conflicted resource.
Preset public RNTI can be used for conflicted resource indicate DCI middle CRC (Cyclic Redundancy Check,
Cyclic check code) scrambled.CRC is a kind of a kind of hash function that brief fixed digit check code is produced according to data, main
To be used for the mistake detected or verification data is transmitted or is likely to occur after preserving.
Scramble, the data transmitted can be encrypted to presetting the CRC in public RNTI.Can only have
The user terminal of corresponding descrambling capabilities can be obtained and identified indicates DCI containing the conflicted resource for presetting public RNTI.Tool
Body, the method for scrambling belongs to prior art, will not be repeated here.
Conflicted resource indicates DCI as a kind of DCI of new definition, the DCI that its structure length etc. may be with reference format, example
Such as " DCI 0 ", " DCI 1A " DCI formats difference, so that user terminal blind check DCI number of times can be increased.
In order to avoid user terminal increases the blind check number of times for DCI, in ascending resource provided in an embodiment of the present invention point
In method of completing the square, the conflicted resource indicates that DCI includes filling data, and the conflicted resource containing filling data indicates DCI length
Degree is consistent with the DCI length of reference format.
Because filling data do not have specific meaning, so filling data can be arbitrary data mode, and
In indicating DCI in conflicted resource, resource informations of one or more sPUSCH in the upper occupancy of frequency domain may be contained, so
Conflicted resource indicates that the length of the filling data in DCI is not also fixed.As long as ensureing that generated conflicted resource indicates DCI's
Length is consistent with the DCI length of reference format.
For example, with reference to table 1, table 1 is a kind of structure type that conflicted resource indicates DCI.
Table 1
In table 1 containing three sPUSCH the upper occupancy of frequency domain resource information, and containing preset public RNTI, preset
Public RNTI is used to indicate that the CRC in DCI is scrambled to the conflicted resource.
Conflicted resource indicates that each information can represent that first three field is used to refer in table 1 with a field in DCI
Show resource informations of each sPUSCH of user terminal in the upper occupancy of frequency domain, DCI is indicated due to conflicted resource and adjusted for up
The DCI format 0 of degree is compared, the field except indicating resource information, and conflicted resource indicates no longer to include DCI lattice in DCI form
Other fields in formula 0.Therefore, multiple sPUSCH resource information can be included in the form that conflicted resource indicates DCI
Field.For example, when upstream bandwidth is 20MHz, the resource of resource allocation is that other field lengths in 13 bits, DCI format 0 are tired out
Meter can accommodate the field of second resource information；When upstream bandwidth is less than 20MHz, as resource allocation field subtracts in proportion
It is few, and the length of other fields is fixed, other field lengths are accumulative can to accommodate more than two sPUSCH resources instruction
Field.
Filling data cause the conflicted resource to indicate that DCI length is identical with the DCI length of reference format.It is readily appreciated that
It is that the conflicted resource described in table 1 indicates that DCI structure type is only a kind of schematical structure type, in actual applications
It can also as needed be adjusted, as long as disclosure satisfy that the function of conflicted resource instruction DCI in the embodiment of the present invention, then all may be used
To be used as available structure type.
Optionally, in uplink resource allocating method provided in an embodiment of the present invention, it is characterised in that described if so, then
The communication base station generates conflicted resource indicating downlink control information DCI, including：
As multiple sPUSCH on frequency domain consecutive hours, communication base station by multiple sPUSCH the upper occupancy of frequency domain resource believe
Breath, merges into a merging resource information.
Communication base station generates the conflicted resource and indicates DCI, and the conflicted resource indicates that DCI includes the merging resource letter
Breath.
As shown in figure 5, Fig. 5 represents a TTI subframe, the TTI subframes can be divided into two sTTI, wherein ordinate
Frequency domain is represented, abscissa represents time domain, and region 501 is the first user terminal the first PUSCH to be sent, and region 502 is second
User terminal the 2nd PUSCH to be sent, region 503 is the 3rd user terminal the first sPUSCH to be sent, and region 504 is the
Four user terminals the 2nd sPUSCH to be sent, it is seen that region 503 and region 504, on the vertical scale continuously, that is to say, that first
SPUSCH and the 2nd sPUSCH are continuous on frequency domain.
In this case, communication base station merges into one by multiple sPUSCH in the resource information of the upper occupancy of frequency domain
Merge resource information, so can be when the conflicted resource of generation indicates DCI, it is not necessary to a plurality of sPUSCH occur in frequency domain
The resource information of upper occupancy, can only include a merging resource information.
For example, for the subframe shown in Fig. 5, if wherein the first sPUSCH and the 2nd sPUSCH resource information not by
A merging resource information is merged into, then the conflicted resource produced indicates that DCI can be as shown in table 2,
Table 2
When the first sPUSCH and the 2nd sPUSCH resource information is merged into one article of merging resource information, then what is produced rushes
Prominent resource indicates that DCI can be as shown in table 3,
Table 3
When conflicted resource indicates that one is comprised only in DCI merges resource information, each user terminal can be according to the conjunction
And resource information is punched.It is overlapping with the PUSCH phases transmitted by this user terminal without being found out in a plurality of resource information
Folded sPUSCH resource information, is then punched in the resource information according to the sPUSCH.It is whole so as to improve each user
The efficiency at end, and then improve the efficiency of whole data transmission network.
Referring to Fig. 6, Fig. 6 is the flow of the uplink resource allocating method provided in an embodiment of the present invention applied to user terminal
Figure, including：
Step 601, user terminal receives the conflicted resource indicating downlink control information DCI that communication base station is sent, conflict money
Source indicates that DCI includes resources of the up shared data channel sPUSCH of low time delay scheduled in communication base station in the upper occupancy of frequency domain
Information.
Each user terminal hair of the communication base station typically using the form of broadcast into cell or in base station range
Various types of data and information are sent, user terminal can receive communication base station in real time and send Various types of data and information.And pass therethrough
It is various to be used to distinguish mark of user etc., obtain data and information for different user terminals.
In embodiments of the present invention, user terminal receives the data and information transmitted by communication base station, and therefrom extracts
Conflicted resource indicates DCI.The conflicted resource is indicated in DCI containing one or more sPUSCH scheduled in communication base station in frequency domain
Upper occupancy resource information.
Step 602, user terminal judges whether PUSCH to be sent.
User terminal is received after conflicted resource instruction DCI, it can be determined that whether need what is sent to communication terminal
PUSCH, the PUSCH can send conflicted resource instruction DCI forward direction scheduling of user terminals, and user for communication base station
Terminal is receiving the PUSCH that conflicted resource indicates not send also after DCI.
Step 603, when user terminal has PUSCH to be sent, user terminal judges that conflicted resource is indicated in DCI
The resource information of the sPUSCH upper occupancy in frequency domain, if there is overlapping part on frequency domain with PUSCH to be sent.
When user terminal has PUSCH to be sent, user terminal is obtained wherein in can indicating DCI from conflicted resource
The resource information of the contained one or more sPUSCH upper occupancy in frequency domain.Frequency domain shared by PUSCH to be sent
Resource is known for user terminal, so user terminal can indicate each in DCI according to conflicted resource
The resource information of the sPUSCH upper occupancy in frequency domain, judges PUSCH to be sent on frequency domain, be by with it is one or more
SPUSCH has overlapping afoul part.
Step 604, when conflicted resource indicate DCI in sPUSCH the upper occupancy in frequency domain resource information with it is to be sent
