It is a kind of schematic flow diagram for the feedback method that the embodiment of the present invention provides hybrid automatic repeat-request referring to Fig. 1,
As shown, this method can include:
101, the transmission block TB from data source is received；
Above-mentioned TB includes N number of encoding block group CBG, and above-mentioned N is greater than 1.Referring to Fig. 2, Fig. 2 is a kind of schematic frame of TB
Figure.As shown in Fig. 2, a TB includes multiple CBG, a CBG includes multiple continuous CB.The feedback of hybrid automatic repeat-request
Device receives the transmission block TB from data source, and above-mentioned feedback device can be base station, terminal, server etc. and can carry out instead
The device of feedback.Above-mentioned data source can be base station, terminal, server etc..For example, data source can be base station, instead
Feedback device can be terminal；Data source can be terminal, and feedback device can be base station；Data source is terminal 1, feedback dress
It is set to terminal 2.Fig. 2 is merely exemplary, wherein the CB quantity in the CBG number, each CBG in exemplary each TB is only
The example of Fig. 2 should not be interpreted as with limiting meaning by a kind of example.
102, the corresponding N number of decoding result of N number of CBG in above-mentioned TB is obtained, is solved according to M in above-mentioned N number of decoding result
Code result generates a feedback information；
Above-mentioned M is less than above-mentioned N and is greater than 1.Above-mentioned feedback device can be decoded above-mentioned TB, obtain N in above-mentioned TB
The corresponding N number of decoding result of a CBG.Decoding result is divided into two kinds of successfully decoded and decoding failure as a result, successfully decoded can use 1
It indicates, decoding failure can be indicated with 0.The corresponding N number of decoding result of N number of CBG can be to above-mentioned in the above-mentioned above-mentioned TB of acquisition
Each CB in TB is decoded, and obtains the decoding result of each CB；The corresponding F solution of F CB for being included according to each CBG
Code result determines that the decoding result of each CBG, above-mentioned F are greater than 1, and each CBG includes F CB.The F for being included according to a CBG
The corresponding F decoding result of a CB determines that the decoding result of the CBG can be and judges whether above-mentioned F decoding result is decoding
Success；If so, the CBG successfully decoded, otherwise, CBG decoding failure.Optionally, the friendship of above-mentioned F decoding result is calculated
Collection, if intersection is 1, successfully decoded decodes failure if intersection is 0.For example, if 8 CB that a CBG is included
Corresponding 8 decoding results are respectively 1,0,1,1,1,1,1,1, and the intersection of this 8 decoding results is 0, then CBG decoding is lost
It loses.For example, a CBG includes 4 CB, is failed in corresponding 4 decoding results comprising 1 decoding, 3 successfully decodeds,
Then determine CBG decoding failure.Again for example, a CBG includes 4 CB, and corresponding 4 decoding results are to be decoded into
Function, it is determined that the CBG successfully decoded.It is understood that the CBG is decoded into if the equal successfully decoded of CB that a CBG includes
Function；If one or more than one decoding failure, CBG decoding failure in the CB that a CBG includes.
In a 4 g system, HARQ feedback information is the corresponding feedback information of an i.e. TB as unit of TB.If because
For a few CB in a TB mistake and lead to the re-transmission of entire TB, will cause the waste of system resource, and then reduce system
System performance.HARQ feedback, the corresponding feedback information of a TB are carried out as unit of TB.In another HARQ feedback mode,
HARQ feedback is carried out in the way of CBG, i.e., CB all in a TB is divided into several groups, one by one when carrying out HARQ feedback
CB grouping is that CBG is fed back, and HARQ feedback, the corresponding feedback information of each CBG, in CBG quantity are carried out as unit of CBG
In biggish situation, the expense of control channel still will increase.
Above-mentioned M decoding result is the corresponding M decoding result of M CBG in above-mentioned TB, and above-mentioned M CBG can be continuously
M CBG, be also possible to discontinuous M CBG.The above-mentioned M decoding result according in above-mentioned N number of decoding result generates one
A feedback information can be understood as determining the corresponding feedback information of above-mentioned M CBG.In this manner, it is with M CBG

Section indicates the corresponding above-mentioned M CBG of above-mentioned feedback information.
If above-mentioned M decoding result is successfully decoded, it is determined that the corresponding M CBG of above-mentioned M decoding result is decoded into
Function；If in above-mentioned M decoding result including the decoding result of one or more than one decoding failure, it is determined that above-mentioned M CBG
Decoding failure.Successfully decoded can indicate that decoding failure can be indicated with 0 with 1.If the decoding result of some CBG is 1, table
Show the CBG successfully decoded；If the decoding result of some CBG is 0, then it represents that CBG decoding failure.Optionally, above-mentioned M are calculated
The intersection of decoding result, if intersection is 1, it is determined that above-mentioned M CBG successfully decoded, if intersection is 0, it is determined that above-mentioned M CBG
Decoding failure.For example, if the corresponding decoding result of 8 CBG is respectively 1,0,1,1,1,1,1,1, this 8 decoding results
Intersection is 0, then CBG decoding failure.If above-mentioned M CBG successfully decoded, above-mentioned M CBG does not need to retransmit, if above-mentioned M
CBG decoding failure, then above-mentioned M CBG needs to retransmit.For example, if 4 CBG decoding failures, data source need again
Send this 4 CBG；If this 4 CBG successfully decodeds, data source does not need to retransmit this 4 CBG.
Above-mentioned aiming field indicates the range of the corresponding CBG of above-mentioned feedback information, i.e., the corresponding CBG collection of above-mentioned feedback information
It closes.The corresponding above-mentioned feedback information of the above-mentioned above-mentioned M CBG of generation can be according to the decoding result of above-mentioned M CBG and above-mentioned

It is corresponding with the decoding result of above-mentioned M CBG, it can be decoding failure, be also possible to successfully decoded；The aiming field is CBG
Range information, indicate the feedback information corresponding CBG set；Other fields indicate other information.For example, if feedback
The decoding result that information includes is decoding failure, and aiming field 3-6, then the feedback information indicates that above-mentioned data source is sent out again
Send the 3rd CBG to the 6th CBG；If the decoding result that feedback information includes is successfully decoded, aiming field 3-6, the then feedback
Information designation date source does not need to retransmit the 3rd CBG to the 6th CBG.Fig. 3 is merely exemplary, wherein exemplary feedback
The form of field and above-mentioned aiming field that information is included is only a kind of example, should not be interpreted as having by the example of Fig. 3
There is limiting meaning.
In the embodiment of the present invention, the decoding result according to M CBG determines the corresponding decoding result of the M CBG, and
Generate the corresponding feedback information of M CBG, it is possible to reduce control the consumption of information resources, and can accurately feed back the M
The corresponding decoding result of CBG.
103, above-mentioned feedback information is sent to above-mentioned data source end.
Above-mentioned feedback device can send above-mentioned feedback information to above-mentioned data source end by control channel.Above-mentioned feedback letter
Breath can indicate the M CBG that the M CBG that above-mentioned data source needs to retransmit or the above-mentioned feedback device of instruction are properly received.
