Stating, which can be understood as, executes the function, method or step using this kind of device.
Based at least following reason can determine in 5G system using the HARQ feedback engineering reliability in LTE compared with
It is low, it is specific as follows：
One, for the high requirement of reliability and time delay that 5G system transmits data, if the transmission of HARQ feedback
Mistake, for example correct decoding result is accidentally transmitted as to wrong decoding result, then it will lead to the redundant retransmission of data, increase number
According to the time delay of transmission, while causing the waste of system resource；
Two, in LTE system, the range that a HARQ feedback influences is one or several transmission block (transmission
Block, TB), code block (code block, the CB) number for including in a TB is the orders of magnitude of the units to tens, therefore
The CB number that HARQ feedback influences is more than ten or tens；And in 5G system, the range that a HARQ feedback influences is one
The CB number for including in a or several TB, a TB is several hundred or even thousands of, therefore the CB number that a HARQ feedback influences also is
It several hundred or even thousands of, is affected to system.
Based on described above, the embodiment of the present invention will propose the design scheme for being applied to HARQ feedback process in 5G system,
It is designed for the process of HARQ feedback in 5G system.By the design of this HARQ feedback process, HARQ feedback is improved
Reliability, the process of HARQ feedback is adjusted in addition combined with the concrete condition transmitted in communication system, can be by the negative of system
It carries control in the reasonable scope, guarantees the performance of system.
In subsequent embodiment, receiving end is illustrated by taking terminal as an example, it is to be appreciated that receiving end if it is base station,
So the information of HARQ number of repetition can be obtained in base station, execute HARQ feedback according to repeat number progress can
With, therefore it must be terminal that subsequent citing, which should not be construed as receiving end,.
Referring to Figure 1, Fig. 1 is a kind of control method of mixed automatic retransfer feedback provided in an embodiment of the present invention, specifically
It is as follows：
101：Base station generates configuration information, and the number of repetition of mixed automatic retransfer feedback is carried in the configuration information；
The number of the mixed automatic retransfer feedback is used to indicate the number of repetition that terminal sends the feedback of mixed automatic retransfer；
In this step, base station needs to determine the number of repetition for the HARQ feedback for including inside configuration information, this hair first
Bright embodiment provides two kinds of optional implementations for obtaining the parameter, as follows：
A：Number of repetition is determined according to the channel quality between the base station and the terminal, if channel quality declines,
Increase the number of repetition, otherwise reduces the number of repetition.
It is understood that HARQ feedback will be easier to be correctly received, then can if channel quality is preferable
Need not retransmit many times；Channel resource can be saved in this way.
In an optional embodiment, the parameter preset for measuring channel is divided at least two preset parameters by base station
Range, the corresponding preset number of repetition of each preset parameter area, base station is according to its letter between the terminal
Quality corresponding parameter area in road determines number of repetition.Wherein, when the channel quality of the preset parameter area characterization is higher,
Corresponding preset number of repetition is fewer.
For example, base station is when determining the number of repetition for the HARQ feedback for including inside configuration information, under channel
The first number of retransmissions is used when row Signal to Interference plus Noise Ratio SINR is -5dB~0dB；Using the second re-transmission time when downlink SINR is 0~10dB
Number；Third retransmission number is used when downlink SINR is 10~20dB；Downlink SINR uses the 4th number of retransmissions, institute when being greater than 20dB
First to fourth number of retransmissions is stated to be sequentially reduced.
B：Load according to system current control channel determines number of repetition, if the load number of current control channel drops
It is low, then increase the number of repetition, otherwise reduces the number of repetition.
It is understood that repetition can increase control if sending multiple HARQ feedback if the load of control channel is very big
The load of channel can reduce the occupancy to channel resource using less number of repetition in this case.
In an optional embodiment, the load of current control channel is divided at least two preset loads by base station
Range, the corresponding preset number of repetition of each preset loading range.Base station is according to its letter between the terminal
Quality corresponding parameter area in road determines number of repetition.Wherein, the load number of the preset loading range is bigger, corresponding
Default number of repetition is fewer.
For example, base station is when determining the number of repetition for the HARQ feedback for including inside configuration information, in systems together
When the number of users that accesses when being 0~5 using the first number of retransmissions, the second number of retransmissions, number of users are used when number of users is 6~15
Third retransmission number is used when 16~30, uses the 4th number of retransmissions when being greater than 30, first to fourth number of retransmissions is successively
Reduce.
Two schemes of above A, B can comprehensively consider, and can also independently execute, the embodiment of the present invention does not make uniqueness to this
It limits.

It may not necessarily dynamic change；The latter can be applied to the number of repetition for dynamically configuring HARQ feedback.L1 signaling concrete form sheet
Inventive embodiments do not make uniqueness restriction, such as：Downlink Control Information (downlink control can be used
Information, DCI) or other L1 signalings.Wireless heterogeneous networks (Radio Resource Control, RRC) signaling
Or the mode of L1 signaling, it can increase HARQ number of repetition (HARQ Repeat Number, HRN) field wherein
Mode realizes, which can in the extension information of the above signaling or elsewhere, as long as can be configured the reception of information
Rectify and really obtain, the embodiment of the present invention does not make uniqueness restriction.

Person 3G etc.；In the present embodiment, when terminal carries out HARQ feedback using code block group, illustrate that terminal is led to using 5G system
Letter, base station send configuration information in the case where terminal newly eats dishes without rice or wine to be communicated using 5G, more can targetedly promote 5G
The lower problem of HARQ feedback engineering reliability under the application scenarios of communication uses other kinds of the case where eating dishes without rice or wine for terminal
Under whether need to send the configuration information embodiment of the present invention then not limit.
103：After terminal receives above-mentioned configuration information, above-mentioned configuration information is decoded, obtains above-mentioned number of repetition；
104：Carry out data transmission between base station and terminal, it is assumed that for terminal as receiving end, it is anti-that terminal needs to be implemented HARQ

Configuration mode 2：Base station is dynamically configured by the number of repetition that L1 signaling carries out HARQ feedback to terminal, is lifted
For example, a field, HARQ number of repetition (HARQ Repeat Number, HRN), to indicate end can be increased in DCI
End carries out the number of repetition of HARQ feedback.
202：Base station carries out data transmission to terminal, after decoding terminals, the HARQ feedback that is configured according to base station in step 201
