Below in conjunction with the accompanying drawings, method provided by the invention and terminal device are described in detail with specific embodiment.
As shown in Figure 1, the method provided in an embodiment of the present invention for carrying out reply process includes:
Step 101, according to the transfer resource that each Transmission Time Interval TTI is terminal scheduling, and transfer resource is received
The time delay of the check results of carried data establishes response message table;
Step 102, reply process is carried out according to response message table and check results.
In implementation, method provided in an embodiment of the present invention can be used in the process of uplink and downlink scheduling of resource, execute master
Body is mainly base station, and base station with terminal during carrying out scheduling of resource, either ascending resource scheduling, downlink resource tune
The process of degree or retransfer scheduling, the method that reply process provided by the invention can be applied.
During the uplink and downlink scheduling of resource of the prior art, every processing operation that control plane is related to is still based on base station
Institute service terminal sum is carried out, base station carry out reply process when, need to be traversed for all of base station current service every time
Terminal, thus in base station control plane processing capacity it is relatively low.
And method provided in an embodiment of the present invention, it can be according to response message table and check results and the end message determined
Carry out reply process.That is, the embodiment of the present invention can pass through the end message that is stored in response message table, and control
The check results that face receives carry out reply process, judge whether terminal needs to carry out re-transmission data dispatch.
In implementation, for the response message epitope of foundation in base station, it is also base station that the main body of response message table is established in execution, and
Response message table is mainly used for carrying out the end message of the terminal of scheduling of resource in storage resource scheduling process, says for convenience
The bright embodiment of the present invention, uses the form of response message table, and others are able to record that the mode of end message is also applied for this
The method of invention, for example, establishing the binding relationship between scheduling resource and end message, according to binding relationship, determination is provided
The corresponding end message of terminal etc. of source scheduling.
Wherein, end message when may include multiple TTI scheduling in response message table, when dispatch for each TTI,
The mode for the progress reply process that inventive embodiments provide is essentially identical;Meanwhile for the institute for carrying out scheduling of resource in current TTI
There is terminal, the mode for carrying out reply process is also essentially identical, that is, establishes and carried out using response message table the process of reply process
It is similar.
Wherein, the transfer resource that the transfer resource in step 101 can be retransmitted with right and wrong, can also be the uplink of re-transmission
Resource or the downlink transfer resource of re-transmission, the process of three is much like, thus following is only the transmission of non-re-transmission with transfer resource
It describes in detail to method provided in an embodiment of the present invention for resource.
In implementation, transfer resource is the transfer resource of non-re-transmission, or the uplink transmission resource retransmitted, or the downlink retransmitted passes
Defeated resource, the process that three establishes response message table is identical, and the sequential for only establishing response message table is slightly different, below for
When transfer resource is the transfer resource of non-re-transmission, the sequential for establishing response message table is introduced.
Optionally, if transfer resource is the transfer resource of non-re-transmission, the end for carrying out scheduling of resource is needed in each TTI
When end is scheduled, response message table is established.
That is, need the terminal for carrying out scheduling of resource during carrying out uplink and downlink scheduling of resource in each TTI,
Establish response message table.The process of response message table is established in lower mask body introduction.
Optionally, step 101 specifically includes:Transfer resource, reception transfer resource institute according to each TTI for terminal scheduling
The time delay of the check results of data and the length of response message table are carried, determines that transfer resource is corresponding in response message table
Call number;It will be in the corresponding end message storage to the corresponding memory space of call number in response message table of terminal.
That is, base station can be eventually according to each TTI during carrying out the uplink and downlink scheduling of resource of non-re-transmission
Hold the transfer resource dispatched, the length of the time delay D 0 for the check results for receiving the carried data of transfer resource and response message table
M determines the corresponding call number in response message table of transfer resource, and the terminal corresponding end that will carry out scheduling of resource at this time
In client information storage to the corresponding memory space of call number in response message table.It can say through a preset mapping rule
Then, the corresponding call number of transfer resource for terminal scheduling is calculated, and then the terminal for carrying out scheduling of resource at this time is corresponding
In end message storage to the corresponding memory space of the call number in response message table.
For convenience of explanation, a kind of possible form is enumerated below for preset mapping ruler, but merely to explanation,
It is not intended to limit the present invention embodiment, the mode that others establish response message table is also applied for the present invention.
For example, a TTI being presently processing is directed to, if the transfer resource that current TTI is terminal scheduling is frame number
And subframe numbers, wherein frame number is SFN, and subframe numbers SUBSFN, it is that SUBSFN is held that control plane, which receives frame number by SFN, subframe numbers,
The time delay for carrying the check results of data is D0 subframe, then can acquire base station control plane according to following equation one, two, three and connect
Receive the frame number CTRL_SFN and subframe numbers CTRL_SUBSFN of check results.
W0=Floor ((SFN*10+SUBSFN+D0) %10240);Formula one
CTRL_SFN=Floor (W0/10);Formula two
CTRL_SUBSFN=W0%10;Formula three
Wherein, W0 is intermediate variable, and Floor () indicates downward rounding, as Floor (3.4) is equal to 3.
Assuming that frame number is 100, subframe numbers 0, control plane receives the time delay of the check results of the carried data of transfer resource
It is 8, then according to formula one, two, three, calculates frame number and subframe numbers that control plane receives check results;
W0=Floor ((100*10+0+8) %10240)=1009;
CTRL_SFN=Floor (1009/10)=100;
CTRL_SUBSFN=1009%10=9;
Therefore, it is possible to it is 100 to acquire control plane to receive the frame number of check results, subframe numbers 9.
When wherein, for uplink, terminal sends the data to base station, and control plane receives the carried data of transfer resource
Check results be that the data that send of the terminal that receives of 1 pair of layer of base station are decoded the check results that verification obtains, be used for
Indicate whether base station has correctly received the data of terminal transmission, wherein solution code check passes through, then it represents that correctly it is received, otherwise,
Indicate that garbled-reception is either not received by the data of base station transmission at all;When for downlink transfer, base station is sent to terminal
Data, the check results that control plane receives the carried data of transfer resource are terminals after the data for receiving base station transmission, end
End judges whether data are correctly received, wherein terminal log passes through according to solution code check, then it represents that correctly it is received, otherwise, table
Show garbled-reception or is not received by the data of base station transmission at all;Then, terminal is provided the result of verification by uplink
Source is sent to base station, downlink transfer of the base station to terminal transmission data before base station can judge after receiving according to check results
Whether process is correct.
And after determining the frame number and subframe numbers that control plane receives check results, it is also necessary to determine in response message table
Storage location, that is, the call number stored.
For example, base station according to following rule, can determine the end message for the terminal for carrying out scheduling of resource in response message
Corresponding storage location in table, to realize the cyclic mapping of transfer resource and response message table.
Assuming that control plane receives the frame number and subframe numbers of check results, i.e. the frame number value at place is X, and subframe numbers value is
The length of Y, response message table are M (call number of answer list is from 0 to M-1), then carry out the corresponding terminal of terminal of scheduling of resource
The index that information is stored in response message table is:
(X*10+Y) %M formula four
According in a upper example, the length of frame number 100, subframe numbers 9, response message table is 40, then end message
It is (100*10+9) %40, i.e., 9 position that USER_INF0, which should be stored in response message table index number,.
By taking TD-LTE is transmitted as an example, as shown in Fig. 2, the signal established for response message table provided in an embodiment of the present invention
Scheme, two radio frames are depicted in figure, frame number is respectively N, N+1, and USER_INF0 represents frame number N, the terminal that subframe numbers 1 are dispatched
Information, if N is equal to 100, the time delay that control plane receives check results is 8, then, can be in the hope of control according to formula one, two, three
Face receive check results frame number be 100, subframe numbers 9, when arrived frame number be 100, subframe numbers be 9 TTI when, base station according to
Above-mentioned rule, i.e. formula four, it is 9 to acquire the call number that the corresponding current TTI of transfer resource is corresponded in response message table, thus,
Base station can store end message into the memory space where call number in response message table 9.
In implementation, the embodiment of the present invention is not limited in end message determined above storage location in response message table
Mode, the embodiment of the present invention, other storage modes are also applied for the embodiment of the present invention to the above method solely for the purpose of illustration
Method.
Base station can be carried the verification of data according to each TTI by transfer resource, the reception transfer resource of terminal scheduling
As a result the length of time delay and response message table determines the corresponding call number in response message table of transfer resource, i.e., logical
Above-mentioned preset mapping ruler is crossed, the corresponding call number of transfer resource can be calculated, and then determine rope from response message table
The corresponding end message of quotation marks, the as corresponding end message of transfer resource, and according to determining end message and receive
Check results carry out reply process.
For example, it is assumed that the frame number that base station is the transfer resource of terminal scheduling is 100, subframe numbers 1, control plane receives verification
As a result time delay is 8, and the length of response message table is 40, then base station can determine the control of base station according to formula one, two and three
The frame number that face processed receives check results is 100, subframe numbers 9, and according to the mapping ruler of formula four, determines that the terminal is corresponding
It is (100*10+9) %40, i.e., 9 position that end message, which is stored in response message table index number,.
After the corresponding end message of terminal for determining progress scheduling of resource, believed according to check results and the terminal determined
Breath carries out reply process.
In implementation, end message includes the relevant information of the terminals such as terminal iidentification ID and HARQ process number.
That is, in fact, base station can carry out response according to the check results received and the end message of determination
Processing.If base station carry out response judgement the result is that the check results are correct, discharge in the determining end message
HARQ process numbers;Otherwise (such as base station garbled-reception is either not received by the data of terminal transmission at all), executes the end
The corresponding HARQ of HARQ process numbers in client information.
Base station carries out resource tune after each TTI has carried out reply process in response message table when will delete current TTI
The corresponding end message of terminal of degree.Optionally, after step 102, further include:If it is determined that institute's progress in need in current TTI
The corresponding reply process of terminal of scheduling of resource is all completed, and the corresponding end messages of current TTI in response message table are deleted.
That is, before carrying out re-transmission data, the end message in current TTI is deleted.It, can be in implementation
It is just to delete corresponding end message after each terminal for carrying out scheduling of resource completes reply process, can also be etc. in the TTI
After the terminal in need for carrying out scheduling of resource all carried out reply process, then to delete current TTI in response message table corresponding
All end messages.
In implementation, the transfer resource in step 101 can also be the biography of re-transmission in addition to the transfer resource that can be retransmitted with right and wrong
Defeated resource;Wherein, when transfer resource is the transfer resource of non-re-transmission, the process base of ascending resource scheduling and scheduling downlink resource
This is identical, and when retransmission resource is dispatched, the process of ascending resource scheduling and scheduling downlink resource is also essentially identical, only establishes
The sequential of response message table is different, lower mask body introduction.
One, transfer resource is the transfer resource of non-re-transmission.
If transfer resource is the transfer resource of non-re-transmission, either ascending resource scheduling or scheduling downlink resource, answer
Information table is answered to be required for establishing during carrying out scheduling of resource.Optionally, if transfer resource is the transfer resource of non-re-transmission,
When needing the terminal for carrying out scheduling of resource to be scheduled in each TTI, response message table is established.
In implementation, if transfer resource is the transfer resource (such as base station is for the first time terminal distribution resource) of non-re-transmission, base
Standing can be according to the transfer resource in each TTI being terminal distribution, and the check results of reception the carried data of transfer resource
Time delay, needed in each TTI carry out scheduling of resource terminal be scheduled when, establish response message table.Wherein, it transmits
Resource can be the resource that frame number and subframe numbers etc. carry out scheduling of resource;And it according to transfer resource, receives transfer resource and is carried
The time delay of the check results of data, and and response message table length, terminal corresponding end message storage is believed to response
It ceases in table.And specific determination process, the transmission money of terminal distribution according to above-mentioned formula one, two, three, four, can be calculated as
The corresponding call number in response message table in source, and the corresponding end message of the terminal of current scheduling is stored to call number pair
In the memory space answered, before illustrated in greater detail has been carried out, it is no longer repeated herein.
In implementation, transfer resource is the mistake of the process and the transfer resource that transfer resource is non-re-transmission of the transfer resource retransmitted
Journey is similar (may refer to the above-mentioned detailed illustration process by taking transfer resource is non-re-transmission as an example), only establishes response letter
The sequential for ceasing table is different, thus is not repeated that introducing transfer resource is how the transfer resource process retransmitted establishes response letter herein
Table is ceased, and only introduces the sequential for establishing response message table.
Two, transfer resource is the uplink transmission resource retransmitted.
Optionally, if transfer resource is the uplink transmission resource retransmitted, in the terminal for needing re-transmission data in TTI to retransmitting
When needing the terminal for retransmitting data to carry out re-transmission data dispatch in TTI before carrying out re-transmission data dispatch or to retransmitting, foundation is answered
Answer information table.
That is, the check results when uplink indicate garbled-reception, or when not receiving corresponding check information,
Before base station can need the terminal for retransmitting data to carry out re-transmission data dispatch in re-transmission TTI, synchronized according to ascending HARQ
Characteristic acquires frame number and subframe numbers that control plane obtains the check results that the terminal-pair answers retransmit process number next time, according to above-mentioned
The default mapping ruler of citing, is added to end message in response message table;Or the check results table when uplink
When showing garbled-reception, or not receiving corresponding check information, base station in response message table without adding the verification in advance
The corresponding end message of terminal of mistake, but when carrying out re-transmission data dispatch, which is added to response message
Table.
When the downlink transfer money that transfer resource is re-transmission is described below, the sequential of response message table is established.
Three, transfer resource is the downlink transfer money retransmitted.
Optionally, if transfer resource is the downlink transfer resource retransmitted, in the terminal for needing re-transmission data in TTI to retransmitting
When carrying out re-transmission data dispatch, response message table is established.
That is, the check results when downlink transfer indicate garbled-reception, or when not receiving corresponding check information,
Base station is not necessarily to add the corresponding end message of terminal of the check errors in response message table in advance, but is being retransmitted
When data dispatch, which is added to response message table.
According to the description of the above-mentioned method for carrying out reply process to the embodiment of the present invention, this method is summed up in transfer resource
For non-re-transmission transfer resource when, carry out reply process when overview flow chart.Other situations, it is similar when with non-re-transmission, because
