Definitions
- the present invention relates to the field of wireless communication technologies, and in particular, to a data transmission method and apparatus, and a computer storage medium.
- LTE Long Term Evolution
- the protocol architecture and physical layer parameters of LTE are the same for different service types, that is, without considering the conventional cyclic prefix (CP, Cyclic Prefix) and extended CP.
- the physical layer parameters such as the subcarrier spacing corresponding to the service type, the number of symbols included in the subframe, the symbol interval, and the subframe format are the same.
- RLC Radio Link Control
- ARQ Automatic Repeat ReQuest
- MAC Medium Access Control
- the data retransmission mechanism in LTE adopts the stop equation, that is, the sender temporarily stops every time a data packet is sent, waiting Confirmation information at the receiving end.
- the acknowledgement (ACK, Acknowledgement) of the receiving end new data is transmitted, and when the NACK fed back by the receiving end is received, the last transmitted data packet is retransmitted.
- the transmission fails after the maximum number of HARQ retransmissions is reached the communication is required.
- the ARQ retransmission process of the RLC further ensures the reliability of data transmission, which inevitably introduces a large delay and is difficult to meet the delay-sensitive service requirements.
- the two-layer retransmission mechanism is used to ensure the reliable transmission of data. That is, the ARQ of the RLC layer and the HARQ of the MAC layer to implement data reliability transmission will cause a large transmission delay (because ARQ is heavy). The transmission is too slow, ARQ can only improve the reliability), that is, the delay is needed in exchange for reliability.

本发明涉及无线通信技术领域,尤其涉及一种数据传输方法及装置、计算机存储介质。
长期演进通信系统(LTE,Long Term Evolution)中,针对不同的业务类型,LTE的协议架构及物理层参数相同,即在不考虑常规循环前缀(CP,Cyclic Prefix)和扩展CP的情况下,不同业务类型对应的子载波间隔、子帧包含的符号数、符号间隔、子帧格式等物理层参数相同,就用户面而言,数据的可靠传输需要经过无线链路控制(RLC,Radio Link Control)的自动重传请求(ARQ,Automatic Repeat reQuest)以及媒体接入控制(MAC,Medium Access Control)的混合自动重传请求(HARQ,Hybrid ARQ)过程来保证,当然,可以配置HARQ的最大重传次数,在发送端收到HARQ的否定确认(NACK,Negative Acknowledgement)后将发起重传过程,因此,LTE中数据重传机制采用停等式,即发送端每发送一个数据包就暂时停下来,等待接收端的确认信息。当收到接收端的确认(ACK,Acknowledgement)时,则发送新的数据,当收到接收端反馈的NACK,则重传上次传输的数据包。并且,如果达到HARQ最大重传次数后,仍然传输失败,则需要通
过RLC的ARQ重传过程来进一步保证数据传输可靠性,这样势必会引入较大的时延,难以满足时延敏感的业务要求。
LTE中通过两层重传机制来保障数据的可靠性传输,即通过上文所述的RLC层的ARQ和MAC层的HARQ来实现数据可靠性传输将造成较大的传输时延(因为ARQ重传太慢,ARQ只能提高可靠性),即需要通过时延来换取可靠性,未来第五代移动通信(5G,Fifth Generation)移动通信中,针对超可靠低时延(URLLC,Ultra-Reliable and Low Latency Communications)业务,即同时满足高可靠和低时延要求的业务类型,如果依然采用LTE中的两层重传架构,在满足可靠性要求的同时将很难满足URLLC类型业务的低时延要求,因此,为达到URLLC的低时延和高可靠需求,5G中研究的方法之一是去激活层2(L2,Layer2)的ARQ重传功能,只保留HARQ一层重传来获取时延增益,但是,如果将L2的ARQ重传去激活,又很难满足高可靠要求(比如要求错误概率低于10^5),因此,如何实现数据传输的高可靠和低时延是有待解决的问题。
