Description

多跳路径的数据传输方法及装置 技术领域
本申请涉及通信技术领域，尤其涉及一种多跳路径的数据传输方法及装置。
背景技术
第三代合作计划(3rd generation partnership project,3GPP)长期演进(long term evolution，LTE)的第12版本Rel-12中引入设备间通信(device to device,D2D)技术并且进行了标准化，目的是让用户设备(user equipment,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 3Relay)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(5G new radio,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覆盖内边缘UE(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。

上述各种组合中，终端设备之间的链路可以是侧行链路，但不仅限于侧行链路应用场景，可以是非授权频谱系统，可以是综合接入和回传链路系统，侧行链路不受限于D2D，V2V，V2X场景等。
此外，第一设备与第二设备也可以形成直连路径，即第一设备传输的数据可以直接被第二设备接收到。
其中，所述第一目标传输路径为所述至少一条传输路径中的传输路径，且第一目标传输路径可以包括至少一条传输路径中的一条或者多条传输路径，在此不做限定。
步骤S202：所述第三设备根据所述第一控制信息确定是否中转所述至少一个传输块中的目标传输块；当所述第三设备根据所述第一控制信息确定中转所述至少一个传输块中的目标传输块时，所述第三设备发送第二控制信息。
其中，所述第三设备根据所述第一控制信息确定是否中转所述至少一个传输块中的目标传输块，包括：所述第三设备根据所述第一控制信息判断是否自身属于目标中转设备；当所述第三设备根据所述第一控制信息判断自身属于目标中转设备时，所述第三设备确定中转所述至少一个传输块中的目标传输块，即，所述第三设备中转所述至少一个传输块中的目标传输块。
其中，所述第三设备根据所述第一控制信息中转所述至少一个传输块中的目标传输块，包括：所述第三设备根据所述第一控制信息传输或中转传输或发送或传输所述至少一个传输块中的目标传输块。
其中，所述目标传输块可以是为所述至少一个传输块中的一个或者多个传输块，在所述第三设备根据所述第一控制信息中转至少一个传输块中的目标传输块之前，所述第三设备根据所述第一控制信息中至少一个传输块的第一路径指示信息确定待该第三设备中转的目标传输块，可选的，所述目标传输块的第一路径指示信息中包括第三设备的标识。
其中，当所述目标传输块对应的至少一条传输路径中第三设备的下一跳为第二设备，则第二控制信息中不包括路径指示信息，当所述目标传输块对应的至少一条传输路径中当前第三设备的下一跳为中转设备时，则第二控制信息中包括第二路径指示信息，该中转设备为所述第三设备包括的多个中转设备中的一个。
可见，本申请实施例中，第三设备接收来自第一设备的第一控制信息，第一控制信息包括至少一个传输块的第一路径指示信息，第一路径指示信息用于指示至少一个传输块的第一目标传输路径，然后，第三设备根据第一控制信息中转所述至少一个传输块中的目标传输块，并发送第二控制信息。可见，第三设备在进行数据中转时，无需根据基站的调度进行中转，本端可以根据第一路径指示信息自主确定需要进行中转的目标传输块进行数据中转，并向下一跳发送第二控制信息，有利于提高多跳传输路径中数据传输效率。
在一个可能的实现中，所述第二控制信息包括所述目标传输块的第二路径指示信息，所述第二路径指示信息用于指示所述目标传输块的第二目标传输路径。
其中，第二控制信息中包括第二路径指示信息，表明所述目标传输块对应的至少一条传输路径中第三设备的下一跳不是上述第二设备，第三设备的下一跳仍然为中转设备，该中转设备可以根据第二路径指示信息继续中转目标传输块。
可见，本实现中，第三设备在中转目标传输块后发送的第二控制信息中包括目标传输块的第二路径指示信息，有利于实现传输块的多跳传输，在每一跳传输时包含下一跳的指示信息，提升数据传输的灵活性和效率。
在一个可能的实现中，所述第一控制信息包括源标识和目的标识。

其中，源标识(source ID)可以是源节点(source node)的节点标识(node ID)，或者是源设备(source device)的设备标识(device ID)，或者是通过通信码流(traffic flow)定义的一种源标识，此处不做唯一限定。同样的，目的标识(destination ID)可以是目的节点(destination node)的节点标识(node ID)，或者是目的设备(destination device)的设备标识(device ID)，或者是通过通信码流(traffic flow)定义的一种目的标识。
节点标识，设备标识，源标识，或者目的标识中任何一者可以包括以下任意一种：绝对标识；绝对标识中的一部分取值；所关联的节点的无线网络临时标识(radio network tempory identity,RNTI)；所关联的节点的RNTI的一部分；以及所定义的用于进行转发通信的合作组中的相对标识；且当表示为所述相对标识时，所述设备标识包括组标识与相对标识的联合指示。
其中，目的标识用来标识目标设备。
其中，第一目标传输路径或者第二目标传输路径为能链接到目标设备的传输路径。
作为一种示例，该路径为从源设备开始到目标设备的一跳或者多跳传输路径，或者从任何一个目标中转设备开始到目标设备的一跳或者多跳传输路径，或者，从源设备的下一跳设备开始到目标设备的一跳或者多跳传输路径，或者从任何一个目标中转设备的下一跳设备开始到目标设备的一跳或者多跳传输路径。
可见，本实现中，在第一控制信息或者第二控制信息中包括源标识和目的标识，可以明确至少一个传输块的来源和目的，有利于提升中转设备针对至少一个传输块的传输路径 的选择便捷性和明确性。
在一个可能的实现中，所述第一控制信息为第一侧行链路控制信息(sidelink control information,SCI)，所述第二控制信息为第二SCI。
具体实现中，在第一控制信息为第一SCI和/或第二控制信息为第二SCI时，第一设备、第三设备、第二设备可以是终端设备，可以形成合作组，该合作组的至少一条传输路径可以通过数据传输路径表格进行维护，具体可以由基站等网络设备根据当前合作组中的设备之间的连接关系建立该数据传输路径表格。数据传输路径表可以包含任何能够进行合作通信的路径，且维护传输路径时按照链路条件可以分成不同类型。例如，针对链路条件为中级(medium)的传输路径，支持同时进行数据传输以确保可靠通信，针对链路条件为高级(high)的传输路径，支持独立发送数据，如用于一次传输一个传输块TB，链路条件high和链路条件medium是指链路质量的级别。
上述数据传输路径表具体可以包括一条或多条传输路径的以下信息中的至少一项：设备标识、路径索引、传输能力指示(指示单独传输或者同时传输)、连接的设备标识、链路条件。其中，连接的设备可以为上一跳设备标识或者下一跳设备标识。连接的设备还可以为前一跳设备标识或者后一跳设备标识。连接的设备还可以为前X跳设备标识或者后Y跳设备标识，其中，X大于或等于1，Y大于或等于1。
例如，如图4所示的一种合作组的多跳路径的结构示意图，假设第一设备与第二设备之间有6条传输路径，分别为路径1(path1,P1)(中转设备为UE1)、P2(中转设备为UE3)、P3(中转设备为UE4)、P4(中转设备为UE2)、P5(中转设备为UE5)、P6(中转设备为UE6)。且路径P1、P2、P3的链路条件为high；路径P4、P5、P6的链路条件为medium，属于中等级P2。则该合作组的数据传输路径表可以如表1所示。第一设备标识为UE0，第二设备标识为UE7。
表1.合作组的数据传输路径表
设备标识 路径索引 传输能力指示 连接的设备标识 链路条件
1 Path1 0 0，7 High
3 Path2 0 0，7 High
4 Path3 0 0，7 High
2 Path4 1 0，7 Medium
5 Path5 1 0,，7 Medium
6 Path6 1 0，7 Medium
其中，传输能力指示0表示支持独立发送数据，传输能力指示1表示支持同时传输数据；下一跳中转设备0表示无下一跳中转设备，即当前传输路径为2跳路径。
可见，本实现中，针对合作组中的设备，中转设备无需根据基站的调度进行中转，本端可以根据路径指示信息自主确定进行数据中转，有利于提高合作组多跳传输路径中数据传输的灵活性和效率。
在一个可能的实现中，所述第一路径指示信息包括用于指示所述第一目标传输路径的信息或者用于指示第一目标中转设备的信息，其中，所述用于指示第一目标中转设备的信息包括以下任意一种：所述第一目标中转设备标识；位图bitmap信息；

其中，当所述第二路径指示信息包括用于指示所述第二目标传输路径的信息，且所述用于指示所述第二目标传输路径的信息为路径标识时，所述第三设备提前向周围设备广播或传输了与所述第三设备相关联的路径标识。所述周围设备包括下述至少一项：一个或者多个中转设备，或第二设备。所述广播或传输可以承载于RRC信令，也可以承载于PSSCH。

举例而言，bitmap信息为01010000，其中，bit位为1的bit位表示需要进行中转传输的中转设备，即第一目标中转设备或第二目标中转设备为合作组中的第二设备和第四设备。
可见，上述实现中，路径指示信息可以直接包含目标传输路径的指示信息，可以完整指示整条传输路径；或者，路径指示信息可以包含目标中转设备的指示信息，从而精确指示目标中转设备的下一跳设备的情况。

例如，如图5所示，第一SCI预留了传输块(transport block1,TB1)、TB2、TB3这三个传输块的资源。
可见，本实现中，至少一个传输块包括了预留的至少一个传输块，有助于中转设备提前预知将要发送数据的传输块资源及发送时刻，因此提前准备数据包，可以避免在该传输块资源上进行别的传输或接收。

举例而言，当第一控制信息为第一SCI，所述至少一个传输块中包括当前调度的TB1和预留的两个TB2、TB3的资源，且为非联合指示，即分别指示时，第一路径指示信息如下所示，依次标注至少两个传输块与对应的第一目标中转设备标识之间的映射关系：resource 1，CUE 1；resource 2，CUE 3；resource 3，CUE 5。则第一目标中转设备中的多个中转设备将根据每个标识与资源的对应关系，将对应资源上传输的数据进行中转传输，即CUE 1对第一个资源上收到的TB1进行中转，CUE 3对第二个资源上收到的TB2进行中转，CUE 5对第三个资源上收到的TB3进行中转。

其中，预设值可以是为1，也可以为0，在此不做限定。
其中，当第一控制信息为第一SCI，预设值为1表示第一目标中转设备时，所述至少一个传输块中包括当前调度的TB和预留的三个TB1、TB2、TB3的资源，且为联合指示时，第一路径指示信息中的第二bitmap如下所示，根据bitmap：10101000，可知预留的三个资源对应的第一目标中转设备包括：CUE 1，CUE 3，CUE 5，即CUE 1对第一个资源上收到的TB1进行中转，CUE 3对第二个资源上收到的TB2进行中转，CUE 5对第三个资源上收到的TB3进行中转。

另外，预留的至少一个资源中的一个或多者的组合可以被联合指示，则bitmap标识根据被联合指示的任何一者或多者的组合依次排列，例如，预留的三个TB1、TB2、TB3中的TB1、TB2、TB3被联合指示，那么第一路径指示信息中的第一bitmap指示对应的目标中转设备对第一个资源上收到的TB1进行中转，第二bitmap指示对应的目标中转设备对第二个资源上收到的TB2进行中转，第三bitmap指示对应的目标中转设备对第三个资源上收 到的TB3进行中转。
可见，本实现中，第一路径指示信息为bitmap标识，且使用联合指示，使一个bitmap标识可以指示多个资源对应的第一目标中转设备，有利于提升第一目标中转设备指示的便捷性，降低数据承载量。
在一个可能的实现中，所述第一控制信息中的第一目标中转设备的信息为所述至少两个bitmap，当所述第一路径指示信息为非联合指示信息时，所述第一路径指示信息包括当前调度的所述传输块与所述第一bitmap之间的映射关系，以及预留的所述至少一个传输块与对应的所述第二bitmap之间的映射关系。
其中，当第一控制信息为第一SCI，所述至少一个传输块中包括当前调度的TB和预留的三个TB1、TB2、TB3的资源，且为非联合指示，即分别指示，且bit位为1的bit位表示需要进行中转传输的第一目标中转设备时，第一路径指示信息中的预留的所述至少一个传输块与对应的所述第二bitmap之间的映射关系如下所示，根据bitmap 1：10100000，可知TB1对应的第一目标中转设备包括：CUE 1，CUE 3，根据bitmap 2：10001000，可知TB2对应的第一目标中转设备包括：CUE 1，CUE 5，根据bitmap 3：00101000，可知TB3对应的第一目标中转设备包括：CUE 3，CUE 5，即CUE 1和CUE3对第一个资源上收到的TB1进行中转，CUE 1和CUE 5对第二个资源上收到的TB2进行中转，CUE 3和CUE 5对第三个资源上收到的TB3进行中转，如图7所示。
SCI:

Resource2，10001000
Resource3，00101000
可见，本实现中，第一路径指示信息为bitmap标识，且使用非联合指示，对每个传输块分别使用bitmap进行指示，该种指示信息可以对每个传输块指示多个第一目标中转设备，使多个第一目标中转设备均对相应的传输块进行中转，有利于提升第一目标中转设备指示的灵活性和多样性，提升数据中转效率。
在一个可能的实现中，resource 1，resource 2，resource 3中任何一者或多者的组合可以被联合指示，则bitmap标识根据对应resource 1，resource 2，resource 3中任何一者或多者的组合依次排列。例如，虽然resource 1，resource 2，resource 3被联合指示，第一bitmap用于指示中转第一个传输块的目标中转设备，第二bitmap用于指示中转第二个传输块的目标中转设备，第三bitmap用于指示中转第三个传输块的目标中转设备。
在一个可能的实现中，所述至少一个传输块对应多条传输路径。

其中，所述至少一个传输块对应多条传输路径可以包括每个传输块均对应多条传输路径，在该种情况下，所述第一控制信息中还包括每个传输块对应的所述多条传输路径是否同时传输的指示信息，如上述描述的CUE 1和CUE 3对第一个资源上收到的TB1进行中转，即TB1对应两条传输路径，如图7所示，所述第一控制信息中还包括两条传输路径是否同时传输的指示信息。
可选的，当包含一个指示域时，每个传输块对应的所述多条传输路径是否同时传输的指示信息可以是该指示域为0，指示不需要同时传输，即可以独立传输；该指示域为1，指示需要同时传输。
其中，所述多条传输路径是否同时传输的指示信息还可以包含于别的指示信息中，不受限于第一控制信息，例如，可以是网络设备发给终端设备的信令，也可以是第一设备发给第三设备的信令。本发明中信令可以为任何RRC信令，媒体介入控制层(media access control,MAC)信令或物理层信令的一种或多种的组合。
可见，本实现中，当每个传输块对应多条传输路径时，第一控制信息中可以包括多条传输路径是否同时传输的指示信息，有利于提升路径指示的清晰性，使中转设备可以有效传输。
在一个可能的实现中，所述第一控制信息中还包括当所述多条传输路径同时传输时，每条传输路径传输的是否为整个传输块的指示信息。
同样的，每条传输路径传输的是否为整个传输块的指示信息还可以包含于别的指示信息中，不受限于第一控制信息，例如，可以是网络设备发给终端设备的信令，也可以是第一设备发给第三设备的信令。本发明中信令可以为任何RRC信令，MAC信令或物理层信令的一种或多种的组合。
举例而言，CUE 1和CUE 3对第一个资源上收到的TB1进行中转，当需要CUE 1和CUE 3同时传输时，CUE 1和CUE 3是传输整个接收到的数据包，或者传输该数据包中的部分，也可以在第一控制信息中进行指示。例如，包含一个指示域，该指示域为00时，指示不需要同时传输，即可以独立传输，该指示域为01时，指示需要同时传输，且每个中转设备(例如，CUE 1和CUE 3)都传输整个接收到的数据包，该指示域为10时，指示需要同时传输，且每个中转设备(例如，CUE 1和CUE 3)只传输该数据包中的部分。具体的，当传输该数据包中的部分时，如果有两个中转UE(例如，CUE 1和CUE 3)，可以是对数据包二等分，各自传输一部分；如果有三个中转UE，可以是对数据包三等分，各自依次传输第一部分到第三部分；还可以是依据预设规则进行分隔为几部分，所述预设规则可以是预先设置的或者信令配置的。
同时，第一SCI包含源标识和目的标识，从而使得接收端能够对接收到的多个中转设备发送的部分数据进行合并。
可见，本实现中，当每个传输块对应多条传输路径时，第一控制信息中可以包括多条传输路径是否同时传输，以及每条传输路径对应的第一目标中转设备是否传输整个传输块的指示信息，有利于提升路径指示的清晰性和多样性，提升数据传输效率。
在一个可能的实现中，所述方法还包括：所述第一设备根据所述至少一个传输块上数据的数据优先级和信道状态指示(channel state information,CSI)确定所述至少一个传输块对应的所述一个或者多个中转设备。
其中，具有较高优先级的数据选择具有high CSI(如上述表1所示)的路径的中转UE，具有较低优先级的数据选择具有medium CSI(如上述表1所示)的路径的中转UE。
可见，本实现中，第一设备根据数据优先级和CSI确定中转设备，有利于提升中转设备确定的合理性，提升数据中转效率。
