Description
Technical field
The present invention relates to communication technique field, more particularly to a kind of data transmission method, device, equipment and storage medium.
Background technology
Existing wireless communication system, such as 3GPP Long Term Evolutions (Long Term Evolution, LTE) system introduce
Hybrid automatic repeat request technology (Hybrid Automatic Repeat Request, HARQ) improves the transmission of physical layer
Reliability.Transmitted for same Physical Downlink Shared Channel (Physical Downlink Shared Channel, PDSCH)
Block (Transport Block, TB), emitter (such as base station) send the data of the processing to the transmission block to receiver, such as
Fruit receiver (such as terminal) is not properly received the transmission block of emitter transmission.Emitter is just repeatedly retransmitted, until
The transmission block is correctly received by terminal, or the transmission of the transmission block is terminated after reaching maximum retransmission.For
Each data transfer of the emitter, receiver be required for feeding back uplink affirmative acknowledgement (Acknowledgement, ACK)/
Negative response (Negative Acknowledgment, NACK).
In existing LTE system, so that downlink data transmits as an example, the corresponding PDSCH of schedule information transmission, with
And the feedback of an ACK/NACK information；If necessary to retransmit PDSCH transmission block, data transmission procedure just needs repeatedly to be adjusted
Degree, multiple PDSCH re-transmission, and multiple ACK/NACK feedback of the information.For example, downlink data transmission of the prior art
Process is as shown in Figure 1.Using emitter as base station, receiver is illustrates exemplified by terminal, for every number of the PDSCH transmission block
According to transmission, schedule information is sent to terminal by base station first, and schedule information is (such as first time schedule information, second of schedule information
Etc.) in indicate the information such as the PDSCH for issuing terminal transformat, time-domain resource, frequency domain resource.For dynamic dispatching mould
Formula, carries the control channel of schedule information and the data channel of carrying data message is located at same downlink times interval
In (Transmission Time Interval, TTI), one of them descending TTI is a master data transmission unit.Then
In time-domain resource, frequency domain resource in instruction, the data transmission format of terminal as indicated carries out PDSCH demodulation, and upper
Whether on row ACK/NACK channels the ACK/NACK feedback of the information of the PDSCH transmission block will be received correctly to base station.Base
Whether uplink ACK/NACK the channels stood by detection terminal transmission, detection terminal are received correctly the PDSCH transmission block.
If base station detects terminal and is not correctly received the PDSCH transmission block, base station can carry out again PDSCH scheduling and
PDSCH data are sent, and terminal can demodulate the PDSCH of re-transmission again, and carry out the feedback of ACK/NACK information.
At present, in order to meet the potential application in the fields such as intelligent transportation, automatic Pilot, industrial automation, 5G newly eats dishes without rice or wine to connect
Entering technology (New Radio Access Technology, NR) needs to support super reliable, low time delay communication URLLC business
The wireless communication needs of (Ultra Reliable and Low Latency Communication, URLLC).URLLC business
It is required that the communications of low time delay, high reliability, typically, it is desirable to which unidirectional transmission time delay is less than 0.5ms, the error rate of packet
In below 1e-5, or packet reliability index more than 99.999%.
Meeting a kind of plain mode of the transmission demand of low time delay and high reliability is, improves the reliable of single data transfer
Property, i.e., once pass pair.That is desirable to the code check that single transmission is reduced using more frequency domain resources, and then reduces the mistake of packet
Probability by mistake, but this method can bring declining to a great extent for system efficiency of transmission.Main cause is the reliability of URLLC business
It is required that significantly larger than strengthen mobile broadband (enhanced Mobile BroadBand, eMBB) business, if single using lifting
The method of secondary transmission reliability causes the overall resource utilization of system not high, it is necessary to the very more frequency domain resource of primary distribution,
And reduce the number of users of multiplexing in same TTI.Therefore, meet that URLLC business needs are still main by repeatedly retransmitting
Candidate scheme.
The prior art being transmitted several times for support, after receiving PDSCH data every time, terminal is required for instead
An ACK/NACK information is presented, larger time interval, adds URLLC business between causing PDSCH re-transmission and just passing
Propagation delay time.
By taking a kind of system configuration as an example, as shown in Fig. 2 using descending transfer transmitter as base station, receiver is exemplified by terminal
Explanation.The subcarrier spacing of system is 60kHz, and each TTI contains 7 orthogonal frequency division multiplexi (Orthogonal
Frequency Division Multiplexing, OFDM) symbol, each TTI time span is 0.125ms.Just pass
PDSCH is sent in initial TTI.In view of the processing time of terminal, uplink ACK/nack message may be sent out in first TTI earliest
Give base station.Because PDSCH is not demodulated correctly by terminal, base station side receives negative response NACK, by dispatching again
And after Base-Band Processing, the first time that base station could most carry out PDSCH early in the 3rd TTI retransmits.It can be seen that it is initially transmitted to weight
Between biography, due to sending and receiving ACK/NACK, at least two TTI when elongatedness, that is, 0.25ms are added.
It can so cause two consequences, first, cause the retransmission opportunity of the PDSCH in 0.5ms to reduce；Retransmission opportunity in same time
Reduce, be unfavorable for repeatedly retransmitting and improve reliability.Second, PDSCH propagation delay time is added, i.e., at least increases 0.25ms, shadow
Ring the delay performance of URLLC business.
The content of the invention
In view of the foregoing, it is necessary to a kind of data transmission method and device are provided, reduce processing delay, when saving
