Description

多跳路径数据传输方法及相关装置 技术领域
本发明涉及通信技术领域，尤其涉及一种多跳路径数据传输方法及相关装置。
背景技术
3GPP长期演进LTE的第12版本Rel-12中引入设备间通信D2D技术并且进行了标准化，目的是让用户设备UE之间能够直接通信，以满足公共安全Public Safety等新兴业务的需求。(注，此时的D2D，只能支持网络覆盖范围内的UE发现，以及UE和UE之间的通信，这种通信可以是单播也可以是广播，并且支持全部UE在网络覆盖内、部分UE在网络覆盖内、全部UE在网络覆盖外的场景)。LTE的Rel-13中引入设备到网络中继UE-to-Network relaying技术并且进行了标准化。这种技术使得网络可以利用Rel-12引入的D2D技术，通过层3中继Layer 3 Relay扩展网络的覆盖，让网络覆盖外的UE能借助网络覆盖内的UE获得服务。此外，在Rel-14/15/16版本，车辆对外界信息(Vehicle-to-Everything，V2X)作为D2D技术的一个主要应用顺利立项。V2X具体又包括车辆对车辆(Vehicle-to-Vehicle，V2V)、汽车对行人(Vehicle-to-Person，V2P)、汽车对基础设施(Vehicle-to-Infrastructure，V2I)、汽车对路侧设备(Vehicle-to-RSU，V2R)各种应用需求。V2V指的是基于LTE的车辆间通信；V2P指的是基于LTE的车辆与人(包括行人、骑自行车的人、司机、或乘客)的通信；V2R指的是基于LTE的车辆与路边装置(RSU)的通信，另外还有一种V2N可以包括在V2I中，V2N指的是基于LTE的车辆与基站/网络的通信。路边装置(RSU)包括两种类型：终端类型的RSU，由于布在路边，该终端类型的RSU处于非移动状态，不需要考虑移动性；基站类型的RSU，可以给与之通信的车辆提供定时同步及资源调度。无论是现有的D2D、V2V、V2X，还是第五代移动通信技术5G V2X以及未来的侧行链路应用场景,都可以进行用户协作UE cooperation。
从通信理论发展和应用场景需求角度来看，新空口NR第17版本Rel-17是用户协作技术商业化的良好时机。从3GPP标准发展的历史来看，用户协作所包含的UE之间的通信、UE-to-Network relaying等技术，以前在3GPP中都有一定的研究。其中，UE-to-Network relaying是一个UE帮助另一个UE和基站进行通信的技术，也叫中继Relay技术。可以认为，以前研究过的D2D技术和Relay技术均是用户协作技术的一个组成部分。
目前，相关标准讨论的用户协作技术中的数据中继仅限于基站到覆盖内边缘UE，再到覆盖外UE，即当从基站发送数据时，如果第二设备处于基站的信号覆盖范围之外，则目标UE无法直接接收到来自基站的传输，可以由基站统一调度通过in coverage edge UE进行数据中转，如何更加灵活的实现多跳路径中的数据中转是需要解决的问题。
发明内容
本发明实施例提供一种多跳路径数据传输方法及相关装置，能够使得多跳路径中的设备自主确认数据转发，提高多跳路径中数据传输的灵活性和效率。

可见，本示例中，针对用户协作组中的设备，中转设备无需根据网络设备的调度进行中转，本端可以根据路径指示信息自主确定进行数据中转，有利于提高用户协作组多跳路径中数据传输的灵活性和效率。
在一个可能的示例中，所述路径指示信息包括用于指示所述目标传输路径的信息，或者用于指示目标中转设备的信息；

具体实现中，第三设备可以根据获取的路径指示信息确定是否存在从本端设备到第二设备的路径信息，如果存在，则确定中转所述第一控制信息调度的侧行链路数据。
可见，本示例中，由于第二控制信息包括源标识和目的标识，从而第三设备的下一跳设备接收到该第二控制信息时，若下一跳设备为第二中转设备，则第二中转设备可以根据本端获取的路径指示信息确定转发数据，若下一跳设备为所述第二设备，则第二设备确定接收数据，确保数据中转传输的持续性和准确度。
在本可能的示例中，所述第一控制信息和所述第二控制信息还包括用于转发数据的传输时间间隔。

其中，所述优先级指示信息为服务质量(QoS，quality of service)指示信息，或者业 务质量指示信息，或者优先级信息。
其中，所述第一预设门限可以是预定义的门限值，此处不做唯一限定。
具体实现中，若所述链路质量信息高，则所述第三设备可以单独发送第二控制信息，若所述链路质量信息低，则所述第三设备可以与其他设备同时发送第二控制信息。
此外，若检测到所述优先级指示信息小于第一预设门限，则所述第三设备可以不发送数据或者通过其他方式来决策是否发生数据。此处不做唯一限定。
可见，本示例中，通过优先级指示信息约束中转设备的数据发送，避免所有合法数据均被中转设备无差别发送而加大中转设备的数据传输压力，均衡传输资源利用率。
在一个可能的示例中，所述路径指示信息包括所述第三设备的发送判决因子；所述第三设备发送第二控制信息，包括：所述第三设备生成发送决策随机数；判断出所述发送决策随机数与所述发送判决因子满足预设大小关系，发送所述第二控制信息。

在一个可能的示例中，所述第一控制信息还包括优先级指示信息；所述路径指示信息还包括所述第三设备的发送判决因子；所述第三设备发送第二控制信息，包括：所述第三设备检测到所述优先权指示信息小于所述第一预设门限时，生成发送决策随机数；判断出所述发送决策随机数与所述发送判决因子满足预设大小关系，根据所述链路质量信息发送所述第二SCI。
其中，所述发送判决因子可以是百分比值，如表1中所列的100％、60％等。所述发送决策随机数的取值范围为[0，1]。
此外，若检测到所述优先级指示信息大于或等于所述第一预设门限，则所述第三设备直接根据所述链路质量信息发送所述第二SCI。
可见，本示例中，通过优先级指示信息在第一层级约束中转设备的数据发送，通过发送判决因子来进一步约束中转设备在第二层级进一步约束中转设备的数据发送，如此可以避免中转设备因需要转发所有合法数据而加大数据传输压力，均衡传输资源利用率。
