Description

一种数据传输方法、设备及存储介质 技术领域
本申请涉及通信领域，尤其涉及一种数据传输方法、设备及存储介质。
背景技术
设备到设备(D2D，Device to Device)通信是一种基于侧行链路(SL，Sidelink)的传输技术，与传统的蜂窝系统中通信数据通过基站接收或者发送的方式不同，D2D通信是采用终端到终端直接通信的方式。若侧行链路工作在非授权频谱，在发送数据块之前需要进行先听后说(Listen Before Talk，LBT)检测；LBT的检测结果影响着数据块发送的成功率，因此，如何提高侧行链路传输中的数据块的传输效率是一直追求的目标。
发明内容
为解决上述技术问题，本申请实施例提供了一种数据传输方法、设备及存储介质。
第一方面，本申请提供了一种数据传输方法，包括：若第一设备利用第一免授权调度资源初传数据块或重传数据块失败，则所述第一设备利用第二免授权调度资源重传所述数据块。

具体实施方式
为了能够更加详尽地了解本申请实施例的特点与技术内容，下面结合附图对本申请实施例的实现进行详细阐述，所附附图仅供参考说明之用，并非用来限定本申请实施例。
在对本申请实施例进行详细描述之前，对本申请实施例涉及的相关信息进行说明。
侧行链路的工作载波可以是2.4GHz、5GHz、6GHz或者60GHz等非授权频谱。网络设备向用于发送数据或接收数据的终端设备配置侧行链路通信的侧行传输资源和其他控制参数。网络设备可以通过动态调度(Dynamic Scheduling)的方式为终端设备分配侧行传输资源；或者网络设备可以为终端设备分配免调度授权(Configured Grant，CG)传输资源。对于网络设备为终端设备分配CG传输资源的分配方式，主要包括两种方式：第一类配置授权(type-1 configured grant)和第二类配置授权(type-2 configured grant)；具体的：
第一类配置授权：网络设备通过无线资源控制(Radio Resource Control，RRC)信令为终端设备配置侧行传输资源，该RRC信令配置包括侧行传输资源的周期、时域资源、频域资源、解调参考信号(Demodulation Reference Signal，DMRS)、调制编码方式(Modulation and Coding Scheme，MCS)等在内的全部传输资源和传输参数。当终端设备接收到该高层参数后，可立即使用所配置的传输参数在配置的时频资源上进行侧行传输。
第二类配置授权：采用两步的资源配置方式，即网络设备通过RRC信令和下行控制信息(Downlink Control Information，DCI)分配资源的方式；首先，由RRC信令配置包括时频资源的周期、冗余版本、重传次数、混合自动重传请求(Hybrid Automatic Repeat reQuest，HARQ)进程数等在内的传输资源和传输参数，然后由DCI激活第二类配置授权的传输，并同时配置包括时域资源、频域资源、MCS等在内的其他传输资源和传输参数。终端设备在接收到RRC信令时，不能立即使用该高层参数配置的资源和参数进行侧行传输，而必须等接收到相应的DCI激活并配置其他资源和传输参数后，才能进行侧行传输。此外，网络设备可以通过DCI去激活该配置传输，当终端设备接收到去激活的DCI后，不能再使用该传输资源进行侧行传输。
发送终端设备(Transmit User Equipment，TX UE)，接收网络设备发送的传输资源配置和控制参数，TX UE发送数据给接收(Receive，RX)UE，并且等待RX UE的反馈信息。
RX UE：接收网络设备发送的的传输资源配置和控制参数。在接收到TX UE的数据包以后，如果能够正确解码，那么在物理侧行反馈信道(Physical Sidelink Feedback Channel，PSFCH)信道上反馈HARQ ACK。如果解码失败，那么在PSFCH信道上反馈负确认信息(HARQ NACK)。
相关技术中，若侧行链路工作在非授权频谱，在发送数据块之前需要进行LBT检测；若LBT检测结果为发送数据块的信道忙碌，则数据块发送失败。在该场景下，需要依赖于网络设备的动态调度来重传数据块，即网络设备动态调度用于重传数据块的资源；如此，可能会引入额外的时间延迟，若终端设备与网络设备之间的Uu接口也工作在非授权频谱的时候，还可能无法及时获得用于重传数据块的资源。
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行描述，显然，所描述的实施例是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
本申请实施例的技术方案可以应用于各种通信系统，例如：全球移动通讯(Global System of Mobile communication，GSM)系统、码分多址(Code Division Multiple Access，CDMA)系统、宽带码分多址(Wideband Code Division Multiple Access，WCDMA)系统、通用分组无线业务(General Packet Radio Service，GPRS)、长期演进(Long Term Evolution，LTE)系统、LTE 频分双工(Frequency Division Duplex，FDD)系统、LTE时分双工(Time Division Duplex，TDD)、通用移动通信系统(Universal Mobile Telecommunication System，UMTS)、全球互联微波接入(Worldwide Interoperability for Microwave Access，WiMAX)通信系统或5G系统等。
示例性的，本申请实施例应用的通信系统100可以如图1所示。该通信系统100可以包括网络设备110，网络设备110可以是与UE120(或称为通信终端设备、终端设备)通信的设备。网络设备110可以为特定的地理区域提供通信覆盖，并且可以与位于该覆盖区域内的UE进行通信。可选地，该网络设备110可以是GSM系统或CDMA系统中的网络设备(Base Transceiver Station，BTS)，也可以是WCDMA系统中的网络设备(NodeB，NB)，还可以是LTE系统中的演进型网络设备(Evolutional Node B，eNB或eNodeB)，或者是云无线接入网络(Cloud Radio Access Network，CRAN)中的无线控制器，或者该网络设备可以为移动交换中心、中继站、接入点、车载设备、可穿戴设备、集线器、交换机、网桥、路由器、5G网络中的网络侧设备或者未来演进的公共陆地移动网络(Public Land Mobile Network，PLMN)中的网络设备等。
该通信系统100还包括位于网络设备110覆盖范围内的至少一个UE120。作为在此使用的“UE”包括但不限于经由有线线路连接，如经由公共交换电话网络(Public Switched Telephone Networks，PSTN)、数字用户线路(Digital Subscriber Line，DSL)、数字电缆、直接电缆连接；和/或另一数据连接/网络；和/或经由无线接口，如，针对蜂窝网络、无线局域网(Wireless Local Area Network，WLAN)、诸如DVB-H网络的数字电视网络、卫星网络、AM-FM广播发送器；和/或另一UE的被设置成接收/发送通信信号的装置；和/或物联网(Internet of Things，IoT)设备。被设置成通过无线接口通信的UE可以被称为“无线通信终端设备”、“无线终端设备”或“移动终端设备”。
可选地，UE120之间可以进行D2D通信。
