Source, but directly the data are sent to base station using pre-assigned resource.Base station is then by reception techniques such as blind examination sides pre-
The data that receiving terminal apparatus is sent in the resource first distributed.It is referred to as exempting to authorize number using the data that Grant-free is transmitted
According to the above-mentioned pre-assigned resource for Grant-free transmission is referred to as exempting from authorization resources.
To promote the transmission reliability for exempting from authorization data, terminal device can will exempt from authorization data using transmission technology is repeated
It is sent to base station.In repeating transmission technology, terminal device can repeat to send on continuous K (K > 1) a time slot (slot)
Some data, any feedback without waiting base station, for example, NACK or scheduling information etc..As shown in Figure 1, terminal device
When using transmission technology transmission data are repeated, a redundancy versions of the data are sent on each slot
(Redundancy Version, RV), wherein the redundancy versions sent on different slot may be the same or different.

Evolution (Long Term Evolution, LTE) system) in widely applied hybrid automatic request (Hybrid Auto
ReQuest, HARQ) technology be introduced into 5G communication in.In HARQ technology, transmitting terminal is in some slot or continuous multiple slot
After upper initial transmission data, if receive receiving end feedback be not properly received the instruction of the data after, can again transmission should
The redundancy versions of data enable receiving end to merge reception according to the data of the data and initial transmission transmitted again,
To promote the transmission reliability of data.
In order to realize HARQ function, terminal device needs to know that the data transmitted again are corresponding when transmitting data again
Be which initial transmission data, when base station receives the data transmitted again, it is also desirable to know this number transmitted again
According to it is corresponding be which initial transmission data, the number that the data of the initial transmission received could be merged in this way and transmitted again
According to promote the transmission reliability of data.This process is guaranteed by HARQ process, that is, base station receives to be passed again
When defeated data, while it can know that the corresponding HARQ progress information of the data transmitted again then should such as process number (ID)
Again transmission specified number is merged according to data cached in the caching of corresponding HARQ process.
In Grant-free transmission mechanism, terminal device K transmission institute when using transmission technology transmission data are repeated
The HARQ process used be all it is identical, and the HARQ process number of used HARQ process be by this K times transmission in for the first time
What transmission was determined.Therefore, base station needs to detect in K transmission when receiving using the data for repeating transmission technology transmission
Transmission for the first time and judge that the secondary transmission is to transmit for the first time, just can determine that HARQ process used in transmitting for this K times
HARQ process number.
Due in the uncertainty and URLLC scene of the data arrival time of terminal equipment side data transmit it is low when
Prolong requirement, can be used if there is exempting from authorization resources, then terminal device is after data arrival, meeting is in the shortest possible time
Base station is sent the data to using authorization resources are exempted from, this means that terminal device can exempt from authorization resources being arbitrarily configured with
K times for starting to send the data on slot repeats to transmit.For terminal and base station, the initial position for repeating transmission is all not
It is fixed and unpredictable.In this case, the detection transmitted for the first time repeated in transmission is sentenced since base station needs to rely on
Break to determine that terminal device sends HARQ process number used in data, once base station does not detect and judges to pass for the first time
Defeated, then base station can not just determine that terminal device sends HARQ process number used in data.

Start and/or Physical Resource Block-final position Prb-End.As done to specific location information in above-mentioned configuration message
It introduces, just repeats no more here.UE can be according to the Physical Resource Block-initial position Prb-Start or physics of location information
Resource block-final position Prb-End, and exempt from the maximum transmitted number of authorized transmissions resource, then further according to HARQ process
Sequencing, such as ascending order arrangement or descending, determine that this exempts from the corresponding HARQ process number of authorized transmissions resource.For example, base station
2 are configured with for UE and exempts from authorized transmissions resource, and Physical Resource Block-initial position Prb-Start is 10, then corresponding HARQ process
It number is respectively 0 and 1 according to ascending order arrangement, UE receives the configuration message, exempts from authorized transmissions resource according in configuration message
Frequency resource location information 10 determines that the corresponding HARQ process number of authorized transmissions resource of each exempting from is 0, and then realizes UE
Location information by configuring the frequency resource in message can also accurately determine exempt from the corresponding HARQ of authorized transmissions resource into
Cheng Hao.
In optional another embodiment, the network equipment resource distribution message is carried out with HARQ process number it is corresponding, often
The corresponding resource distribution message of a HARQ process number.It is according to the successive suitable of the transmission of resource distribution message that terminal device, which receives,
Sequence determines HARQ process number.If one is exempted from authorization configuration message GrantFree- using above-mentioned configuration message format example
Config includes K resource distribution message GFResources, can be according to GFResources in GrantFree-Config
Sequencing respectively correspond HARQ process 0 to K-1.
In a kind of optional embodiment, if the configuration message that the network equipment such as base station generates in the S301 is also wrapped
It includes: redundancy versions configuration information, using fixation when the redundancy versions configuration information is used to indicate terminal device transmission data
Redundancy versions or variable redundancy versions.The method can also include:
The terminal device is according to the redundancy versions configuration information, using fixed redundancy versions when determining transmission data
Or variable redundancy versions.
The fixed redundancy versions refer to UE in different TTI or in all TTI using the same redundancy versions；
The variable redundancy versions are that different redundancy versions are used in different TTI.
After the completion of the configuration of base station, it is known that each to exempt from the corresponding HARQ process number of authorized transmissions resource, it is receiving UE
Data when determine the HARQ process numbers of data first, then carrying out signal detection, (detection and the process of process number can be unlimited
It is fixed).If it is data are retransmitted, then the reception signal by the data and before merges detection, passes data if it is first, then directly
Detection data is connect, and then parses data.Confirmation message ACK is sent to UE if detecting successfully, otherwise sends and denies message
NACK, ACK/NACK message correspond to 1 bit.If there is multiple parallel HARQ transmissions, base station can send more bit feedbacks to UE
Message, corresponding multiple HARQ processes.
Wherein, HRAQ process number and the redundancy versions RV of data have corresponding relationship, are described in detail below:
The redundancy versions RV of the corresponding data of HRAC process number issues base station in the configuration information that base station issues；
As shown in fig. 7, different coding modes, i.e. redundancy may be used when UE repeatedly retransmits a data
Version number RV.For exempting from authorized transmissions, base station, which may can't detect, just to be passed and only detects re-transmission, and not can determine that currently and be
Which time retransmits.If transmission uses different redundancy versions RV every time, base station is difficult to determine currently used when receiving
RV, it is difficult to which data are detected.As shown in Figure 4 and Figure 5, if all transmission all use fixed redundancy versions such as RV0,
RV0 mark version is fixed as 0 RV, and all transmission all use identical redundancy versions RV0, then superfluous without judging when base station is detected
Remaining version substantially reduces the complexity of receiver.
Another optional embodiment, base station send redundancy versions configuration information sheet to UE, if the redundancy versions are matched
Confidence breath include using same or different redundancy versions, such as: 0 be with identical redundancy versions, 1 is with different redundancies
Version, UE are determined using identical redundancy versions according to redundancy versions configuration information or are used different redundancy versions.If making
With different redundancy versions, then according to the following examples, which can number the corresponding relationship with redundancy versions according to TTI,
Determine the redundancy versions used when exempting from authorized transmissions；Alternatively, UE is numbered according to TTI, pair of HARQ process number and redundancy versions
It should be related to, determine the redundancy versions used when exempting from authorized transmissions.Both of these case is described especially by the following examples.
The difference of Fig. 8 and above-mentioned Fig. 4 and Fig. 5 are that the redundancy versions used in Fig. 8 are different, and Fig. 4 and Fig. 5 are used
Fixed redundancy versions.The main differentiation of the embodiments described below and above-described embodiment be exempt from the redundancy versions of authorized transmissions can
With difference.
As shown in figure 8, since UE may exempt from authorized transmissions transmitted over resources upstream data at any one, thereby increases and it is possible to more
It carries out repeating transmission on a TTI.
The first: UE determines that the process of current redundancy versions is as follows according to TTI number:
Current redundancy versions are determined as shown in figure 8, can number according to TTI, and wherein TTI number is 4n, 4n+1,4n+
Redundant version number 0,1,2,3 is respectively corresponded when 2,4n+3.When TTI number is nTTI, corresponding formula may be expressed as:
RV=mod (nTTI, 4)
Due to redundant version number and TTI number binding, and UE may start to exempt from authorized transmissions in any TTI, therefore just pass
Not necessarily select redundancy versions 0.As shown in figure 8, if UE starts to exempt from authorized transmissions in the 4n+1 TTI, according to above-mentioned
The corresponding relationship of TTI number and RV, formula as escribed above will use superfluous TTI number modulus when can determine just biography data
Remaining version 1.It should be noted that above-mentioned formula is not unique, as long as the corresponding relationship with RV can be numbered by TTI,
Determine that redundancy versions are ok.
Second: UE redundant version number can also be numbered according to TTI and HARQ process number joint determines:
As shown in figure 8, when HARQ process number is nHARQ, ID, corresponding formula may be expressed as:
RV=mod (nTTI+nHARQ, ID, 4)
At this point, UE can each TTI the corresponding authorized transmissions resource of exempting from of redundancy versions 0 can be selected to start to transmit, example
As shown in figure 8, if UE starts to exempt from authorized transmissions in the 4n+1 TTI, and select HARQ process 4 is corresponding to exempt from authorized transmissions money
Transmitted in source: nTTI 4n, nHARQ ID is 0, then obtaining corresponding redundancy versions according to above-mentioned formula is 0, needs to illustrate
, above-mentioned formula is not unique, as long as the corresponding relationship with RV can be numbered by TTI, determines redundancy versions all
It can be with.In addition, above-mentioned only one embodiment, if TTI is 4n etc., the value of n can be integer, and n can appointing with round numbers
Meaning numerical value.
To sum up, by determining HARQ process number, redundancy versions and the various corresponding relationships between exempting from authorized transmissions resource etc.,
Solving base station can not determine that terminal device is sent used in data because the number of retransmissions of false judgment data causes
HARQ process number in turn results in the problem of can not decoding, and realizing base station can successfully solve when authorized transmissions data are exempted from reception
Adjusting data, while reducing the complexity of receiver.
