For example, re-transmission TBG number and non-re-transmission CBG, non-re-transmission CBG here that a TB includes can include: sky passes CBG
And/or new biography CBG.If the bit number that TBS includes subtracts the difference for retransmitting the bit number of CBG, further according to the difference and preset value
Between comparison, determine the TB transmission mode be the first mode or second mode.If transmitting mould in the present embodiment
Formula is first mode, then state indication bit is the second value, is used to indicate new biography state.If transmission mode is the second state,
It is then empty biography state.
In some embodiments, the new biography data and re-transmission data may not mix re-transmission.Then at this point, the finger of DCI
Show in a little situations, be used to indicate new biography, is used to indicate re-transmission in other cases.
In this case, if DCI instruction is data new biography, and if the state indication bit is described second to take
Value, then the transmission state for being used to indicate corresponding CBG is new biography state；
If DCI instruction is that data retransmit, and if the state indication bit is second value, for referring to
Show corresponding code block group for empty biography state.
For example, carrying out data transmission for the first time before base station and UE is clearly data new biography, then the state indication bit indicates
Just be new biography state.
In some embodiments, include in the Preset Transfers period such as a time slot or a mini-slot CBG number be it is known,
And the bit number in one Preset Transfer period of instruction that the CBG transmission instruction list includes is also that can be based in user equipment
What decoding obtained.If it was found that the bit number that current CBG transmission instruction list includes is exactly equal to the number of CGB, it is believed that number
According to new biography, then corresponding state indication bit is the when taking two-value, and instruction is new biography state.If the CBG transmission instruction column
Table indicates the CBG number that the bit number in a Preset Transfer period includes greater than the Preset Transfer period, then it is believed that data retransmit,
Then it is believed that instruction is empty biography state when current state indication bit is the second value.
Optionally, the method also includes:

Below in conjunction with above-mentioned any one or more embodiments, a specific example is provided:
Example 1:
This example provides a kind of re-transmission and transmits fast (TB), and the multiple CBG for including in re-transmission TB are only used for retransmitting.In this way
If, one bit map for indicating the transmission state of each CBG in TB is set retransmitting DCI, which has specifically been retransmitted with instruction
A little CBG.Fig. 5 A is a kind of schematic diagram of bit map of the transmission state of the instruction CBG in DCI.Bit as shown in Figure 5A
The CBG number that the bit length and initial transmission TB of figure include is identical, and the CB number that each described re-transmission CBG includes is equal to
The CB number that the CBG for retransmitting the corresponding last transmission of CBG includes.
For example, the bit map retransmitted in DCI includes 4 state indication bits in total, corresponding to take in schematic diagram 5A
Value is [1,1,0,1], wherein " 1 " indicates retransmission state, " 0 " indicates empty biography state.Wherein, the retransmission state refers to institute
The CBG carrying of corresponding instruction retransmits data；The sky biography state refers to that the corresponding CBG indicated does not carry any information.
When UE receives above-mentioned re-transmission DCI, UE can correct understanding arrive: this retransmit data in include just pass data in
1st CBG (i.e. CBG0), the 2nd CBG (i.e. CBG1) and the 4th CBG (i.e. CBG3).
Example 2:
In this example, in order to promote the effective rate of utilization of TB, allow to retransmit both comprising retransmitting CBG in TB, also include new
CBG is passed, then indication problem just becomes increasingly complex.Here re-transmission CBG is for carrying the CBG, new biography CBG that retransmit data
It can be the CBG of carrying new biography data.
It as shown in FIG. 6 and 7, include CBG0 to CBG3 in the TB of n-th transmission, wherein CBG0 and CBG2 needs to retransmit.

The transmission state of situation discussion re-transmission TB.
Situation 1: it retransmits in TB only comprising retransmitting CBG；
For example, the DL portfolio of some UE is less, not new data needs are transmitted, therefore only need to wrap in retransmitting TB
The CBG containing re-transmission.
Situation 2: it retransmits in TB simultaneously comprising retransmitting CBG and new biography CBG；
For example, the DL portfolio of some UE is more, there are the new biography data for largely waiting and being transmitted, therefore in retransmitting TB
Simultaneously comprising retransmitting CBG and new biography CBG.
It transmits each CBG transmission mode in instruction list in CBG to select from 3 kinds of transmission states, comprising: { new biography, again
Pass, empty pass } 3 kinds of transmission states.Empty pass is properly termed as not passing again in this example, i.e., does not carry on corresponding CBG and need to pass
It is defeated by the data of UE.
This example proposes a kind of indicating mode that the HARQ based on CBG is retransmitted, comprising:
List is indicated comprising CBG transmission mode in DCI, wherein each CBG transmission mode in list is transmitted from 3 kinds
It is selected in state, comprising: { new biography, re-transmission, empty biography }.
1 bit indication of each CBG transmission state, wherein agreement " 1 " represents re-transmission and " 0 " represents new biography or empty biography.When
So in some instances, " 0 " representative retransmits and " 1 " represents new biography or empty biography.
Re-transmission is represented with " 1 " below and " 0 " represents new biography or empty biography, is described.
And indicate the new biography that " 0 " indicates, or empty biography, it can be indicated with dominant mode, recessive manner can also be carried out
It is indicated.
Dominant instruction:
As shown in Figure 5 B, the new biography indicated in order to facilitate UE corresponding " 0 ", or also include 1 ratio in DL DCI when empty biography
Special instructions field, to indicate in CBG transmission mode " 0 concrete meaning represented.For example, retransmitting the ratio in DCI in schematic diagram 5B
Special bitmap includes 5 bits in total, is divided into the domain A and the domain B.The corresponding domain indication bit in the domain A totally 1 bit, the corresponding state in the domain B
Indication bit, totally 4 bits, this 4 bits are state indication bit, and corresponding value is [1,1,0,1], wherein " 1 " indicates
Retransmission state, " 0 " indicate empty biography state or new biography state.The i.e. described retransmission state refers to the corresponding CBG carrying weight indicated
Pass data；The new biography state refers to the corresponding CBG carrying new biography data indicated；It is described sky biography state refer to pair
The CBG that should be indicated does not carry any information.
When UE receives above-mentioned re-transmission DCI, UE can correct understanding arrive: " 1 " indicate retransmission state, therefore this retransmit number
It include the 1st CBG (i.e. CBG0), the 2nd CBG (i.e. CBG1) and the 4th CBG (i.e. CBG3) just passed in data in.
And indicate the new biography that " 0 " indicates, or empty biography, then it is indicated by the corresponding domain indication bit in the domain A.
As shown in fig. 6, CBG transmission indication bit includes the state indication bit and 1 domain indication bit of 4 CBG, and
This 4 state indication bits share 1 domain indication bit.The domain indication bit, being used to indicate in corresponding CBG " 0 " is specifically
New biography or empty biography.In Fig. 6 in (n+1)th transmission, the state indication bit of situation 1 and situation 2 is identical, but domain refers to
Show that bit is different, after terminal receives, can be determined second in state indication bit according to the value of domain indication bit
Value instruction is empty biography state or new biography state.
Specifically for example, as shown in fig. 6, also including 1 bit indication domain (being denoted as the domain A) in DL grant DCI, to indicate CBG
0 concrete meaning represented in transmission mode (being denoted as the domain B).
Particularly, as A=1, then 0 in the domain B represents new biography；And as A=0, then 0 in the domain B represents and does not transmit.
Recessiveness instruction:
0 concrete meaning represented in CBG transmission mode is determined by implicit rule；
When excluding the remaining TBS (TBS) after retransmitting CBG greater than preset value, 0 represents new biography；Otherwise, 0 representative does not pass
It is defeated.
As shown in fig. 7, in both cases, retransmitting CBG transmission mode in DCI and indicating that bit is identical in list, all
It is [1,0,1,0], but represents different meanings.
UE passes through 1 in the instruction list of CBG transmission mode first, determines in retransmitting data, includes at least last time transmission
The 1st and the 3rd CBG；And by historical data, the bit number for retransmitting and including in CBG is determined；
UE further passes through MCS and RAI (Resource block Assignment Indication, resource in DCI
Distribution instruction), it determines and retransmits TBS (Transport Block length, transport block size).
UE calculates the remaining TBS for excluding and retransmitting after CBG, i.e.,
Remaining TBS=retransmits TBS- and retransmits the bit number for including in CBG；
UE compares remaining TBS and a certain preset value (X being denoted as, for example, X=6144 bit, corresponds to 1 standard CB length)
Compared with size.
In situation 1,0 bit of remaining TBS ≈ < X, therefore UE asserts that " 0 " in the instruction list of CBG transmission mode represents not
Transmission；And in situation 2, remaining TBS ≈ 19CB >=X, therefore UE asserts that 0 in the instruction list of CBG transmission mode represents newly
It passes.
Example 3:
Based on example 1 and example 2, this example proposes a kind of indicating mode that the HARQ based on CBG is retransmitted, further includes:
Before sending DCI, network side passes through system message or RRC signaling, the ruler of configuration CBG transmission mode instruction list
CBG transmission mode number that is very little, i.e., including in configuration CBG transmission mode instruction list.
Example 4:
Based on example 2, this example further include:
Due to 1 bit indication of each CBG transmission mode, CBG transmission mode number is indicated equal to CBG transmission mode
The bit number of listing field.For example, the corresponding CBG number of a TB is 4, then the bit number that TB transmission instruction list includes is 4.
Example 5:
Based on example 1, this example further includes,
Each to retransmit the CB invariable number for including in CBG when re-transmission, i.e., each CB number for including in CBG that retransmits is equal to
Last time corresponds to CB number included by CBG when transmitting.
In some instances, CB number included in each new biography CBG calculates as follows:
Calculate the corresponding TBS of this re-transmission of total TBS- CBG of this transmission of new biography TBS=；
New biography TBS is subjected to CB segmentation, is obtained new biography CB total number (A)；
