To make the above purposes, features and advantages of the invention more obvious and understandable, with reference to the accompanying drawing to the present invention
Specific embodiment explain in detail.
Referring to Fig.1, the embodiment of the invention provides a kind of data transmission method, the method may include following steps:
Step 11, when receiving the multiplex data of base station transmission, the multiplex data is handled, it is right respectively to obtain
Answer the data to be forwarded of different target terminal.
Wherein, the target terminal is two or more.
In an embodiment of the present invention, ACK/NACK message indicates ACK message or NACK message.Wherein, when TUE success
When receiving data, otherwise feeding back ACK message feeds back NACK message.
In specific implementation, the data-reusing that base station will issue multiple TUE together, forms multiplex data, and should
Multiplex data is sent to same CUE.This process is using downlink, and multiplex data is by Physical Downlink Shared Channel
(Physical Downlink Shared Channel, PDSCH) carrying.Base station passes through Downlink Control Information (Downlink
Control Information, DCI) indicate that the resource of data to be forwarded in the resource allocation and sidelinks of multiplex data is divided
Match.
After CUE is decoded and demultiplexes to multiplex data, the data to be forwarded for corresponding to different TUE is obtained.
In one embodiment of this invention, CUE can first judge the number received after the data for receiving base station transmission
According to whether being multiplex data, after judging the data received as multiplex data, just the multiplex data is handled.
In one embodiment of this invention, CUE can send the physical layer signaling for dispatching the data based on base station,
Whether the received data of judgement are multiplex data.
Wherein, the physical layer signaling can be DCI, naturally it is also possible to be other physical layer signalings.For example, base station can be with
Increase a domain in DCI, is used to indicate the number of target terminal.CUE is based on the domain newly increased in the DCI, it can be determined that institute
Whether the data received are multiplex data.
Step 12, the data to be forwarded is respectively sent to corresponding target terminal.
In specific implementation, the data to be forwarded is sent to corresponding target terminal by corresponding sidelinks by CUE,
The data to be forwarded shares channel (Physical Sidelink Shared Channel, PSSCH) carrying by physics side chain.
CUE also sends side chain control information (Sidelink Control Information, SCI) to each TUE respectively.Each TUE with
Sidelinks between CUE have corresponding SCI and data to be forwarded.SCI is used to refer to the resource allocation of data to be forwarded.
It is understood that due to being base station control model, so the resource allocation field in SCI is also from DCI.Than
Such as, when increasing domain in DCI, corresponding domain correspondingly should also be increased in SCI.
Step 13, the response message that each target terminal is sent is received.
In specific implementation, whether TUE receives success according to data, and feeding back ACK message or NACK message are to CUE.Each
TUE passes through the respectively sidelinks between CUE, to the CUE feeding back ACK/NACK message.
For example, TUE can by physics side chain feedback channel (Physical Sidelink Feedback Channel,
PSFCH 1bit ACK/NACK message) is carried.Wherein, bit 1 can indicate that TUE successful data reception, bit 0 can indicate
TUE does not have successful data reception.If TUE does not have feeding back ACK/NACK message, it may be possible to because of TUE missing inspection SCI.
Step 14, received response message is multiplexed.
It in one embodiment of this invention, can be according to the identity number (TUE ID) of each target terminal, to institute
The response message received is arranged, and the multiplexed response message is obtained.
It specifically, can be according to the ascending order of the identity number of each target terminal, to received response message
It is arranged, received response message can also be carried out according to the descending of the identity number of each target terminal
Arrangement.
It in another embodiment of the invention, can also be according to row of each data to be forwarded in the multiplex data
Column sequence, arranges the response message received, obtains the multiplexed response message.
In specific implementation, described that received response message is multiplexed, can also include:
When not receiving the response message that the target terminal is sent, the corresponding response message of the target terminal is existed
Bit position 0 in the multiplexed response message.
Step 15, multiplexed response message is sent to the base station.
CUE is multiplexed the ACK/NACK message from each TUE, is transmitted to base station by uplink.It is N number of when having
TUE, then multiplexed response message has N-bit.The multiplexed response message is by Physical Uplink Control Channel (Physical
Uplink Control Channel, PUCCH) carrying.
In specific implementation, after base station receives the multiplexed response message that CUE is sent, the tune of data is re-started
Degree, but do not need to retransmit data, the re-transmission of data is carried out by CUE.
Specifically, CUE can receive the base station and be based on the multiplexed response message, and the downlink of transmission controls letter
Breath, the Downlink Control Information are used to indicate data to be retransmitted.CUE is based on the Downlink Control Information, described in retransmission

Wherein, the DCI can serve to indicate that the money of data to be forwarded in the resource allocation and sidelinks of multiplex data
Source distribution.CUE can also judge whether the data of subsequent transmission are multiplex data based on DCI.
Step 202, base station gNB sends multiplex data to CUE.
After CUE demultiplexes received multiplex data, 4 parts of data to be forwarded are obtained, it is subsequent to pass through step 203 respectively
It to step 206, will need to be forwarded to the data of TUE1, TUE2, TUE3 and TUE4, by corresponding sidelinks, be forwarded to corresponding
TUE.CUE also sends corresponding SCI to each TUE respectively, to indicate the resource allocation of data to be forwarded.
It is understood that step 203 may be performed simultaneously to 206, i.e. CUE sends data to TUE1~TUE4 simultaneously.
Step 203 can also be executed sequentially to 206, i.e. CUE sequence sends data to TUE1~TUE4.Specific steps 203 to 206 are held
Row sequence, is not construed as limiting the invention, and within the scope of the present invention.
Assuming that only TUE4 does not have a successful data reception, and the equal successful data reception of TUE1, TUE2 and TUE3, then TUE1,
TUE2 and TUE3 is fed back to CUE, TUE4 in step 210 in step 207, step 208 and step 209 feeding back ACK message respectively
NACK message is to CUE.
It is understood that step 207 is not construed as limiting the invention, and exist to the sequence that executes of step 210
Within protection scope of the present invention.
After CUE receives the response message of TUE1~TUE4 feedback, it is multiplexed.
Specifically, according to the ascending order of TUE identity number, received response message is arranged, then after being multiplexed
Response message are as follows: 1,1,1,0.
According to the descending of TUE identity number, received response message is arranged, then multiplexed response disappears
Breath are as follows: 0,1,1,1.
Assuming that multiplex data is by part1, part2, part3, part4, totally 4 partial datas are constituted, corresponding to be
TUE3, TUE4, TUE2, TUE1, due to only having the corresponding part2 of TUE4 not to be successfully received, according to each described wait turn
It sends out data putting in order in the multiplex data, the response message received is arranged, then it is multiplexed to answer
Answer message are as follows: 1,0,1,1.
If being not received by the ACK message of TUE2 feedback, the corresponding response message of TUE2 multiplexed is answered described
Answer the bit position 0 in message.Disappear for example, arranging obtained multiplexed response in the ascending order according to TUE identity number
Breath is answered are as follows: 1,0,1,0.It is arranged according to the descending of TUE identity number, obtained multiplexed response message is answered are as follows: 0,1,
0,1.It is arranged according to each data to be forwarded putting in order in the multiplex data, it is obtained multiplexed to answer
It answers message to answer are as follows: 1,0,0,1.
After obtaining multiplexed response message, in step 211, the multiplexed response message is sent to base station by CUE
gNB.Subsequent base stations gNB can re-start the scheduling of data based on multiplexed response message.
Specifically, base station gNB first can indicate data to be retransmitted (i.e. step 212), then by CUE to CUE by DCI
The data of TUE4 are retransmitted, and indicate resource allocation (the i.e. step 213) of re-transmission data by corresponding SCI.
