Description

一种数据传输方法及装置、计算机存储介质Data transmission method and device, computer storage medium 技术领域Technical field
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。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.
背景技术Background technique
车联网系统采用基于长期演进(LTE，Long Term Evolution)-设备到设备(D2D，Device to Device)的侧行链路(SL，Sidelink)传输技术，与传统的LTE系统中通信数据通过基站接收或者发送的方式不同，车联网系统采用终端到终端直接通信的方式，因此具有更高的频谱效率以及更低的传输时延。The vehicle networking system adopts a Long Term Evolution (LTE)-to-device (D2D, Device to Device) side-link (SL, Sidelink) transmission technology, and the communication data is received by the base station in a conventional LTE system or Different ways of sending, the vehicle networking system uses the terminal-to-terminal direct communication method, so it has higher spectral efficiency and lower transmission delay.
在3GPP Rel-14中对车联网技术(V2X，Vehicle-to-Everything)进行了标准化，定义了两种传输模式：模式3和模式4。在模式3中，终端的传输资源由基站分配。在模式4中，终端采用侦听(sensing)+预留(reservation)的方式确定传输资源。In 3GPP Rel-14, the vehicle networking technology (V2X, Vehicle-to-Everything) is standardized, and two transmission modes are defined: mode 3 and mode 4. In mode 3, the transmission resources of the terminal are allocated by the base station. In mode 4, the terminal determines the transmission resource by means of sensing + reservation.
在NR-V2X中，需要支持自动驾驶，因此对车辆之间的数据交互提出了更高的要求，如更高的吞吐量、更低的时延、更高的可靠性、更大的覆盖范围、更灵活的资源分配等。为了满足上述要求，在NR-V2X中需要引入多天线传输技术，在多天线传输技术中，发送端如何在多个候选波束中选取最优的波束是基于接收端反馈的最优波束的索引值确定的。In the NR-V2X, automatic driving is required, so higher requirements are placed on data interaction between vehicles, such as higher throughput, lower latency, higher reliability, and greater coverage. More flexible resource allocation, etc. In order to meet the above requirements, a multi-antenna transmission technology needs to be introduced in the NR-V2X. In the multi-antenna transmission technology, how the transmitting end selects the optimal beam among the multiple candidate beams is based on the index value of the optimal beam fed back by the receiving end. definite.
此外，NR-V2X需要支持各种传输方式，如单播(unicast)、组播(groupcast)、广播(broadcast)。在单播传输时需要接收端反馈确认(ACK)/不确认(NACK)信息、信道质量指示(CQI，Channel Quality Indicator)信息，发送端根据接收端的反馈信息可以进行调制与编码策略(MCS， Modulation and Coding Scheme)调整以及判断是否需要进行重传等。In addition, NR-V2X needs to support various transmission methods, such as unicast, groupcast, and broadcast. In the unicast transmission, the receiving end feedback acknowledgement (ACK)/non-acknowledgement (NACK) information and the channel quality indicator (CQI, Channel Quality Indicator) information are required, and the transmitting end can perform modulation and coding strategies according to the feedback information of the receiving end (MCS, Modulation). And Coding Scheme) adjusts and determines whether retransmission is required.

具体实施方式Detailed ways
为了能够更加详尽地了解本发明实施例的特点与技术内容，下面结合附图对本发明实施例的实现进行详细阐述，所附附图仅供参考说明之用，并非用来限定本发明实施例。The embodiments of the present invention are described in detail below with reference to the accompanying drawings.
为便于理解本发明实施例的技术方案，以下分别对车联网中的模式3和模式4进行解释说明。To facilitate understanding of the technical solutions of the embodiments of the present invention, modes 3 and 4 in the Internet of Vehicles are separately explained below.
模式3：如图1所示，车载终端的传输资源是由基站(如LTE中的演进基站(eNB，evolved NodeB))分配的，具体地，基站通过下行链路(DL，Down Link)向车载终端下发用于指示授权(Grant)资源的控制消息；而后，车载终端根据基站分配的资源在SL上进行数据的发送。在模式3中，基站可以为车载终端分配单次传输的资源，也可以为终端分配半静态传输的资源。Mode 3: As shown in FIG. 1, the transmission resource of the in-vehicle terminal is allocated by a base station (such as an evolved NodeB (eNB) in LTE). Specifically, the base station transmits the vehicle to the vehicle through a downlink (DL, Down Link). The terminal sends a control message for indicating the Grant resource; then, the vehicle terminal transmits the data on the SL according to the resource allocated by the base station. In mode 3, the base station may allocate a single transmission resource for the vehicle terminal, or may allocate a semi-static transmission resource for the terminal.
模式4：如图2所示，车载终端采用侦听+预留的传输方式。车载终端在资源池中通过侦听的方式获取可用的传输资源集合，车载终端从该传输资源集合中随机选取一个资源进行数据的传输。由于车联网系统中的业务具有周期性特征，因此车载终端通常采用半静态传输的方式，即车载终端选取一个传输资源后，就会在多个传输周期中持续的使用该资源，从而降低资源重选以及资源冲突的概率。车载终端会在本次传输的控制信息中携带预留下次传输资源的信息，从而使得其他终端可以通过检测该车载终端的控制信息判断这块资源是否被该车载终端预留和使用，达到降低资源冲突的目的。Mode 4: As shown in Figure 2, the vehicle terminal adopts a transmission mode of listening and reservation. The vehicle terminal acquires an available transmission resource set by means of interception in the resource pool, and the vehicle terminal randomly selects one resource from the transmission resource set for data transmission. Since the service in the car network system has periodic characteristics, the vehicle terminal usually adopts a semi-static transmission mode, that is, after the vehicle terminal selects one transmission resource, the resource is continuously used in multiple transmission cycles, thereby reducing the resource weight. The probability of selection and resource conflicts. The vehicle terminal carries information for reserving the next transmission resource in the control information of the current transmission, so that other terminals can determine whether the resource is reserved and used by the vehicle terminal by detecting the control information of the vehicle terminal. The purpose of resource conflicts.
需要说明的是，在LTE-V2X中分别使用模式3表示车载终端的传输资源是由基站分配的，用模式4表示车载终端的传输资源是终端自主选取的，在NR-V2X中，可以定义新的传输模式，本发明对此不做限定。It should be noted that, in LTE-V2X, mode 3 is used to indicate that the transmission resource of the in-vehicle terminal is allocated by the base station, and mode 4 indicates that the transmission resource of the in-vehicle terminal is selected by the terminal autonomously. In the NR-V2X, a new definition can be defined. The transmission mode is not limited by the present invention.
在NR-V2X中需要引入多天线传输技术，多天线可以带来如下几方面的好处：In the NR-V2X, multi-antenna transmission technology needs to be introduced, and multiple antennas can bring the following advantages:
1)更高的传输速率：利用多天线的复用传输方式，在相同的时频资源上可以传输多个数据流，从而提高传输速率。1) Higher transmission rate: Multiple transmission channels can be used to transmit multiple data streams on the same time-frequency resource, thereby increasing the transmission rate.
2)更大的覆盖范围和更高的可靠性：利用波束成型(Beamforming)技术，可以将能量集中在一个很窄的波束内，从而提高接收端的信干噪比(SINR，Signal to Interference plus Noise Ratio)，从而可以提高接收端的接 收成功概率，或者提高传输距离。2) Greater coverage and higher reliability: Beamforming technology can concentrate energy in a narrow beam, thus improving the signal-to-interference ratio (SINR) of the receiver. Ratio), thereby increasing the probability of receiving success at the receiving end or increasing the transmission distance.
这里，通过Beamforming可以提高覆盖范围和可靠性，发送端如何在多个候选波束中选取最优的波束通过以下过程实现：发送端需要进行波束扫描，分别利用不同的波束进行传输；接收端分别接收各个波束传输的数据，从而可以选出一个传输质量最好的波束作为最优波束，并且将该波束的索引值反馈给发送端；在后续的数据传输中，发送端可以采用该最优波束进行数据传输。Here, the coverage and reliability can be improved by Beamforming. How to select the optimal beam among the multiple candidate beams by the transmitting end is implemented by the following processes: the transmitting end needs to perform beam scanning, and respectively uses different beams for transmission; the receiving end respectively receives The data transmitted by each beam, so that a beam with the best transmission quality can be selected as the optimal beam, and the index value of the beam is fed back to the transmitting end; in the subsequent data transmission, the transmitting end can use the optimal beam. data transmission.
上述方案中，接收端需要向发送端反馈波束的索引值，此外，接收端还需要向发送端反馈其他类型的信息，如ACK/NACK信息、CQI信息等，不同的反馈信息可以供发送端做出不同的传输策略，本发明实施例的技术方案在NR-V2X中设计反馈信道来传输反馈信息。In the above solution, the receiving end needs to feed back the index value of the beam to the transmitting end. In addition, the receiving end needs to feed back other types of information, such as ACK/NACK information and CQI information, to the transmitting end. Different feedback information can be used by the transmitting end. A different transmission strategy is adopted. The technical solution of the embodiment of the present invention designs a feedback channel in the NR-V2X to transmit feedback information.
图3为本发明实施例的数据传输方法的流程示意图，如图3所示，所述数据传输方法包括：FIG. 3 is a schematic flowchart of a data transmission method according to an embodiment of the present invention. As shown in FIG. 3, the data transmission method includes:

方式二：第一终端将反馈信息和/或测量信息承载在PSSCH中传输给第二终端。Manner 2: The first terminal carries the feedback information and/or the measurement information in the PSSCH and transmits the information to the second terminal.
