Description

通信方法和通信装置
本申请要求于2019年10月21日提交中国专利局、申请号为201911002518.8、申请名称为“通信方法和通信装置”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域

背景技术
通信网络，例如无线个域网(wireless personal area network，WPAN)、无线局域网(wireless local Area network，WLAN)、无线城域网(wireless metropolitan area network，WMAN)、无线广域网(wireless wide area network，WWAN)等，通常会需要在发送节点和目的节点之间引入中继节点进行数据的接收和转发，从而扩大覆盖范围。
目前，既有采用二层协议架构的通信网络，也有采用三层协议架构的通信网络。采用三层网络架构的通信网络，在物理层完成数据接收之后，经过层二数据链路层的差错控制等处理后才会被递到层三完成数据的路由和转发。采用二层网络架构的通信网络，将路由放在媒体接入控制(media access control，MAC)层完成。
无论是层三或层二的路由管理，由于每一个中继节点在物理层完成数据接收后，都需要递交到层三或层二进行路由选择之后再转发给下一跳节点，导致在每个中继节点处引入比较大的信号处理时延，尤其，当网络规模较大时，信号处理时延问题会随着多跳中继的跳数和连接数增加而变得更加严重。

本申请提出的通信方法中，给同一条路径上的节点配置相同的路径标识信息，在传输信息的过程中，发送该信息的节点在物理层将该信息与该信息的目标路径的路径标识信息关联，并发送关联路径标识信息的信息。为了便于描述，将该节点称为发送节点。如图1中的基站向终端发送信息时，基站为发送节点。
接收到信息的节点可以根据自身存储的路径标识信息是否包括了信息所关联的路径标识信息，来确定是否转发该信息。例如，不包括，则可以丢弃该信息；若包括，则可以转发该信息，或进一步结合其他内容确定是否转发该信息。为了便于描述，将该节点称为 接收节点。例如，图1中的基站向终端发送信息时，终端为接收节点。
进一步地，发送节点发送的信息不仅关联路径标识信息，还可以关联该信息的目的节点标识信息。相应地，接收节点还可以根据信息所关联的目的节点信息确定是否转发该信息。
或者，发送节点发送的信息不仅可以关联路径标识信息，还可以关联该信息的标识信息。相应地，接收节点还可以根据接收的信息所关联的信息标识确定是否转发该信息。
或者，发送节点发送的信息不仅可以关联路径标识信息，还可以关联该信息的目的节点标识信息和该信息的标识信息。相应地，接收节点还可以根据接收的信息所关联的目的节点标识信息和信息标识确定是否转发该信息。
该发送节点可以是终端、基站或中继设备。该接收节点可以是终端、基站或中继设备。该信息可以是控制信息，或可以是数据信息，或既包括控制信息又包括数据信息。
下面将以发送节点发送的信息中包括控制信息和数据信息为例，介绍本申请实施例的通信方法。
例如，发送节点获取信息的目标路径的路径标识信息，根据获取的路径标识信息，生成与该路径标识信息对应的控制信息，并发送包含该控制信息和数据信息的信息，该控制信息用于调度传输该数据信息的资源。其中，控制信息也可以称为控制信道，数据信息也可以称为数据信道，路径标识信息也可以称为路由标识信息。
发送节点可以通过广播的方式发送信息，该信息包含关联了路径标识信息的控制信息。发送节点的邻接节点，或者说位于发送节点覆盖范围内的节点可以接收到该信息。
接收节点接收到该信息后，可以在物理层判断自己是否存储了其中的控制信息关联的路径标识信息，以确定是否需要转发该信息，或者确定是否需要转发该控制信息对应的数据信息，或者确定是否需要转发该控制信息以及该控制信息对应的数据信息。接收节点上没有存储该控制信息关联的路径标识信息的情况下，可以不进行信息转发；否则接收节点可以进行信息转发，或者进一步根据其他信息确定是否进行信息转发。这样，不仅能够降低转发时延，而且有助于扩展网络的覆盖范围，以及避免大量冗余传输。
发送节点可以通过显式或隐式的方式在控制信息中携带路径标识信息。发送节点通过显式的方式在控制信息中携带路径标识信息的一种实现方式为：在控制信息的字段中承载路径标识信息。
发送节点通过隐式的方式在控制信息中携带路径标识信息的一种实现方式包括：通过控制信息的加扰方式来携带路径标识信息。具体地，发送节点使用路径标识信息对控制信道进行加扰。其中，使用不同的路径标识信息对控制信道进行加扰时，加扰得到的控制信道不同。
发送节点使用路径标识信息对控制信道加扰的一种实现方式包括：发送节点根据路径标识信息确定随机序列初始值，并基于所述初始值序列对控制信息进行加扰，从而得到加扰序列。例如，可以按照公式
Figure PCTCN2020122307-appb-000001
对控制信息进行加扰，其中，mod是模运算符号，
Figure PCTCN2020122307-appb-000002
表示异或操作，b是一个子帧内控制信道上的符号序列，B是加扰后的控制信道上的符号序列，c是一个随机序列，随机序列的初始值是根据第一路径标识信息确定的。不同的路径标识信息确定得到的初始值不同，因此根据该初始值对控制信道加扰得到的加扰序列不同。
发送节点使用路径标识信息对控制信道加扰的又一种实现方式包括：发送节点按照现有技术对控制信道进行加扰，例如，根据小区标识确定随机序列的初始值，并使用该初始值对应的随机序列对控制信道上的符号序列进行加扰处理，从而得到加扰序列；然后根据路径标识信息对上述加扰序列进行循环移位处理。
发送节点通过隐式的方式在控制信息中携带路径标识信息的又一种实现方式包括：通过控制信道的时频资源携带路径标识信息。此处的时频资源携带路径信息可以理解为：发送节点根据路径标识信息将控制信道映射到与路径标识信息对应的时频资源上进行传输。
例如，发送节点对控制信道进行加扰、调制、层映射、预编码等处理得到信息序列后，确定与路径标识信息对应的时频资源然后将上述信息序列映射到该时频资源并发送出去。这样，不同的路径标识信息对应不同的时频资源，因此，不同的路径标识信息对应的控制信道在不同的时频资源上进行传输。
当然，发送节点也可以通过上述方式中的任意两种或多种方式的组合在控制信息中携带路径标识信息。
接收节点获取控制信息携带的路径标识信息的方式与发送节点在控制信息携带路径标识信息的方式相对应。
例如，发送节点通过控制信息中的字段携带目标路径的路径标识信息时，接收节点对控制信息进行解调之后，可以在相应字段中获取该目标路径的路径标识信息。
又如，发送节点通过控制信息的加扰方式携带目标路径的路径标识信息时，接收节点可以根据自身存储的路径标识信息对控制信息进行解扰，解扰过程与加扰过程相反；或者，接收节点可以根据自身存储的路径标识信息将控制信息循环移位到相应的位置，此过程与用路径标识信息对控制信息循环移位的过程相反。如果解扰成功，则说明接收节点自身存储的路径标识信息中包括路径标识信息。
又如，发送节点通过控制信息的时频资源携带路径标识信息时，接收节点根据自身存储的路径标识信息生成资源映射信息，并在资源映射信息对应的时频资源上接收控制信息。如果成功接收，则说明接收节点存储的路径标识信息中包括路径标识信息。
相应的，如果发送节点通过任意两种或多种方式的组合实现控制信息携带目标路径的路径标识信息，则接收节点可以采用相应的方式获取控制信息中的路径标识信息。
本申请实施例的一种可能的实现方式中，控制信息还可以关联目的节点标识信息，该目的节点标识信息用于标识目标路径的目的节点。目的节点标识信息可以是目的节点在整个网络或整个小区中的唯一标识；也可以是重新给目的节点分配的标识，该重新分配的标识为目的节点在第一路径标识信息指示的目标路径上的唯一标识，该标识可以由网络侧分配，也可以由目标路径的起始节点或目的节点分配。这样，接收节点通过物理层的信息(控制信息关联的目的节点标识信息)就可以确定本节点是否为目的节点，而无需在较高层进行确定。
控制信息关联目的节点标识信息的方式可以参考控制信息关联路径标识信息的方式，为了简洁，此处不再赘述。例如，目的节点标识信息可以携带于控制信息的字段中。应说明的是，目的节点标识信息的关联方式与路径标识信息的关联方式可以不同。
控制信息关联目的节点标识信息的情况下，接收节点可以根据该目的节点标识信息确定是否需要转发该控制信息，或确定是否需要转发该控制信息对应的数据信息，或确定是 否需要转发该控制信息以及该控制信息对应的数据信息。
例如，接收节点在确定自身存储的路径标识信息包括控制信息携带的路径标识信息时，可以进一步根据该目的节点标识信息确定自己是否为该控制信息的目的节点。若接收节点不是目的节点，则接收节点可以继续转发该控制信息，或转发该控制信息对应的数据信息，或转发该控制信息以及该控制信息对应的数据信息；若接收节点是目的节点，则接收节点可以不再继续转发该控制信息，或不再继续转发该控制信息对应的数据信息，或不再继续转发该控制信息以及该控制信息对应的数据信息。
接收节点从控制信息中获取目的节点标识信息的方式与发送节点通过控制信息携带目的节点标识信息的方式相对应，此处不再赘述。
发送节点通过控制信息携带目标路径的目的节点标识信息，使得接收节点可以及时停止转发，从而节省传输资源。
控制信息没有关联目的节点标识信息的情况下，接收节点可以在更高层从数据信息中获知目的节点的信息，从而判断自己是否为目的节点。
本申请实施例的一种可能的实现方式中，控制信息还可以携带数据标识信息，所述数据标识信息用于标识携带数据标识信息的控制信息或者标识携带该控制信息的信息。该数据标识信息可以由发送节点分配。
控制信息携带数据标识信息的方式可以参考控制信息携带路径标识信息的方式，为了简洁，此处不再赘述。例如，数据标识信息可以携带于控制信息的字段中。应说明的是，控制信息携带数据标识信息的方式与控制信息携带路径标识信息的方式以及控制信息携带目的节点标识信息的方式可以相同，也可以不相同。
控制信息携带数据标识信息的情况下，接收节点可以根据该数据标识信息确定是否转发信息。若接收节点没有接收过该数据标识信息标识的信息，才可以转发该控制信息，或转发该控制信息对应的数据信息，或发送该控制信息以及转发该控制信息对应的数据信息，否则可以不重复发送该控制信息，或不重复发送该控制信息对应的数据信息，或不重复发送该控制信息以及该控制信息对应的数据信息。
在控制信息中携带数据标识信息，可以避免信息的反向传输和重复传输，从而节省传输资源。
若发送节点发送的信息不包括控制信息而只包括数据信息时，通过数据信息携带路径标识信息、目的节点标识信息和数据标识信息的方式，可以参考上述实施例，例如将控制信息替换为数据信息。若发送节点发送的信息仅包括控制信息而不包括数据信息时，在控制信息中携带路径标识信息、目的节点标识信息和数据标识信息中的一项或多项的方法与上述实施例类似，不同之处在于在该控制信息在携带路径标识信息的同时还需携带目的节点标识信息。
本申请实施例中，将节点在物理层对信息进行处理并判断是否对信息进行转发的操作称为物理层转发，或者，可以说该节点具有物理层转发功能。物理层转发功能可理解为节点的物理层接收到信息之后不会将信息递交到上层才转发，而是将接收到的信息在物理层进行处理转发。
与物理层转发功能相对应的是路由转发功能。路由转发功能包括层三网络层或层二MAC层的路由转发，具体可理解为节点的物理层接收信息之后，被递交到层三或层二， 根据层三或层二数据包携带的目的节点的地址判断是否需要进行转发。如果需要转发则查找路由表中目的节点地址对应的下一跳节点地址，然后将信息转发给下一跳节点。
本申请实施例的一种可能的实现方式中，网络中的节点可以既具备路由转发功能又具备物理层转发功能，网络侧可以向这些节点发送配置信息，该配置信息用于指示这些节点在中继转发时使能或关闭路由转发功能，或者，指示这些节点在进行中继转发时使能其路由转发功能，或在进行中继转发时关闭其路由转发功能。其中，关闭路由转发功能即为使能物理层转发功能。
为了便于描述，将进行中继转发时使能其路由转发功能的节点“逻辑节点”，将进行中继转发时关闭其路由转发功能，即采用物理层转发功能的节点称为“物理节点”。
逻辑节点可以使用路由转发功能转发信息，物理节点可以使用物理层转发功能转发信息。例如，前述的接收节点就是使用物理层转发功能来转发信息。
一种配置节点转发功能的方式可以包括：网络侧为网络中每个节点发送配置消息，配置消息指示该节点的类型，一种节点类型为逻辑节点，另一种节点类型为物理节点。配置消息内容可以用1比特信息承载。例如，该配置消息信息比特是‘0’表示将节点配置为逻辑节点，该配置消息信息比特是‘1’表示将节点配置为物理节点。
配置消息可通过预定义配置信息承载；或者通过以下方式中的一种或多种携带：通过无线资源控制(radio resource control，RRC)信令携带；或者通过介质接入控制(medium access control，MAC)层信令携带，例如通过MAC控制单元(MAC control element，MAC CE)携带；或者通过物理层信令携带，例如通过下行控制信息(downlink control information,DCI)携带。
一种配置节点转发功能的方式可以包括：网络中的节点默认是逻辑节点，网络侧发送触发消息触发节点关闭路由转发功能，收到触发消息的节点触发关闭路由转发功能成为物理节点，以采用物理层转发方式。
触发消息可以使用触发消息随机数生成，收到触发消息的节点获取上述触发消息随机数，在确认收到的触发消息随机数有效时，关闭其路由转发功能成为物理节点，采用物理层转发方式。
触发消息可通过预定义配置信息承载；或者通过RRC信令携带；或者通过MAC层信令携带，例如通过MAC CE携带；或者通过物理层信令携带，例如通过DCI携带。
对网络中的节点进行转发功能配置后，网络中的逻辑节点和物理节点的分布示意图如图13所示。其中，虚线圈表示的节点为物理节点，实线圈表示的节点为逻辑节点。也就是说，节点A、D、F和G为逻辑节点，节点B、E和C为物理节点。
本申请实施例的一种可能的实现方式中，节点间的路径可以是节点自己发现并建立的。并且，节点在发现和建立路径的过程中，还可以配置路径标识信息。
在建立路径的一种实现方式中，由一个节点(例如源节点)发送路由请求(route request,RREQ)消息，然后在另一个节点(例如目的节点)发送路由应答(route reply,RREP)消息的情况下，建立这两个端点之间的路径，且给该RREQ消息和该RREP消息共同经过的节点分配同一个路径标识。
其中，源节点可以周期性地发起送路径建立的流程，也可以是在确定需要向目的节点发送信息之后发起路径建立的流程。
例如，配置节点转发功能之后，一个逻辑节点(为描述方便，称为源逻辑节点)发送一个路由请求(route request,RREQ)消息，该消息的目的地址指示的是另外一个逻辑节点(为描述方便，称为目的逻辑节点)。逻辑节点使用广播的方式向周围节点广播RREQ消息，周围的任何一个节点都可能接收到广播的RREQ消息。
如果节点是第一次接收到上述RREQ消息，且消息的目的地址不是自己，则保存接收到的RREQ消息并将接收的RREQ消息广播出去。如果节点之前已经接收过同一个RREQ消息，则丢弃该RREQ消息。
当所述RREQ消息到达目的节点时，即上述目的逻辑节点接收到所述RREQ消息时，上述目的逻辑节点生成RREQ消息的路由应答(route reply,RREP)消息，该RREP消息沿着所述RREQ消息经过的一条或多条路径的反向路径传输到达源逻辑节点。
上述RREP消息或RREQ消息中可以携带一个路径标识，接收到RREP消息或RREQ消息的节点获取并存储上述路径标识。该路径标识可以是上述源逻辑节点在网络中的唯一标识、或者目的逻辑节点在网络中的唯一标识、或者两者的联合编码生成的唯一标识、或者由网络侧分配的唯一标识。
上述例子介绍的是如何建立两个逻辑节点之间的路径，其中，发送RREQ消息的节点也可以替换为物理节点，发送RREP消息的节点也可以替换为物理节点。
图5为本申请一个实施例的建立路径的通信方法的示意性流程图。图5所示的通信方法包括S510至S570。其中，第二设备为建立的路径的源节点、第一设备为建立的路径的中转节点(即，中继节点)，第三设备为建立的路径的目的节点。
S510，第二设备发送RREQ消息，该消息中携带请求建立的路径的目的节点的标识信息。该目的节点的标识信息可以是该目的节点的地址信息。假设该路径的目的节点为第三设备，则该消息中携带第三设备的标识信息。
第二设备可以通过广播的方式发送RREQ消息。
S520，第一设备接收RREQ消息，并保存该消息。
S530，第一设备发送RREQ消息。
其中，可选地，第一设备可以先根据该消息中的目的节点标识信息确定第一设备是不是目的节点。第一设备确定自己不是目的节点，才保存以及转发该消息。
可选地，第一设备可以先确定之前有没有接收过该RREQ消息。第一设备确定自己之前没有接收过该消息，才保存以及转发该消息。
第一设备通过广播的方式发送该消息。
S540，第三设备接收RREQ消息，并发送该RREQ消息的RREP消息，该RREP消息中携带路径标识信息。
其中，可选地，第三设备在发送RREP消息之前，先根据RREQ消息中的目的节点标识信息确定第三设备是否为目的节点。第三设备确定自己是目的节点的情况下，才发送该RREP消息。
可选地，第三设备在发送RREP消息之前，先判断之前是否已经针对该RREQ消息发送过RREP消息。第三设备确定之前没有针对该RREQ消息发送过RREP消息，才针对该RREQ消息发送RREP消息。
S550，第一设备接收RREP消息，并保存该RREP消息中的路径标识信息。
其中，第一设备先确定之前接收过该RREP消息对应的RREQ消息，才保存该RREP消息中的路径标识信息。
可选地，第一设备先确定之前没有保存过该路径标识信息，才保存该路径标识信息。
S560，第一设备发送该RREP消息。
S570，第二设备接收该RREP消息，并存储该RREP消息中的路径标识信息。
其中，第二设备先确定之前发送过该RREP消息对应的RREQ消息，才保存该RREP消息中的路径标识信息。
可选地，第二设备先确定之前没有保存过该路径标识信息，才保存该路径标识信息。
该实施例中，可选地，路径标识信息可以携带在RREQ消息中，该RREQ消息所经过的设备可以预存储该路径标识信息，直到该RREQ消息对应的RREP消息经过这些设备，这些设备才真正存储该路径标识信息，以用来转发携带该路径标识信息的信息。
在建立路径的另一种可能的实现方式中，可以由至少两个节点(路径的源节点和目的节点)去共同发现路径上的中转节点，并给该路径上的节点分配相同的路径标识。
其中，该源节点和目的节点可以周期性地发起路径建立的流程，或者，源节点和目的节点在确定需要在源节点和目的节点之间进行信息的传输之后，再发起路径建立的流程。
例如，配置节点转发功能之后，至少两个逻辑节点分别发送RREQ消息，这至少两个逻辑节点发送的RREQ消息中包含同一个路径标识，并且，这至少两个逻辑节点发送的RREQ消息中携带了可以区别RREQ消息是哪一个节点发送的信息。例如，RREQ消息中可以包含各自对应的逻辑节点的地址标识，或者，不同逻辑节点发送的RREQ消息使用不同的资源传输，包括不同的频域资源或不同的时域资源或不同的时频资源。
这至少两个逻辑节点使用广播的方式向周围节点广播各自的RREQ消息。周围接收到该RREQ消息的节点可以继续广播该RREQ消息。如果有节点接收到至少两个源逻辑节点发送的具有相同路径标识的RREQ消息，则获取并存储RREQ消息中的路径标识。可选地，满足一定的准则的节点才获取并存储RREQ消息中的路径标识，上述准则可以是RREQ消息的接收功率满足要求、或者信噪比(signal to noise ratio,SNR)满足要求等。
上述例子介绍的是如何建立两个逻辑节点之间的路径，其中，这两个逻辑节点中任意一个可以替换为物理节点。
图6为本申请另一个实施例的建立路径的通信方法的示意性流程图。图6所示的通信方法包括S610至S630。其中，第二设备为路径的源节点，第一设备为路径的中转节点，第三设备为路径的目的节点。
S610，第二设备发送第一RREQ消息，该消息中携带路径标识信息。该第一RREQ消息中还携带用于标识第二设备的标识信息。
第二设备可以通过广播的方式发送第一RREQ消息。
S620，第三设备发送第二RREQ消息，该消息中携带路径标识信息。该第二RREQ消息中还携带用于标识第三设备的标识信息。
第三设备可以通过广播的方式发送第二RREQ消息。
S630，第一设备接收第一RREQ消息和第二RREQ消息，并保存其中的路径标识信息。
其中，第一设备接收第一RREQ消息和第二RREQ消息之后，可以先确定这两个RREQ 消息中携带的路径标识信息是否相同。如果相同，则根据这两个RREQ消息中携带的标识设备的信息确定这两个RREQ是否来自不同的设备。如果来自不同的设备，则保存这两个RREQ消息中的同一个路径标识信息。
在建立路径的又一种可能的实现方式中，由节点去发现其所在路径的源节点和目的节点，并给该路径上的节点分配相同的路径标识。可选地，路径上的每个节点可以记录该路径标识和该路径经过哪些节点。
该节点可以周期性地发起路径建立的流程。
例如，配置节点转发功能之后，物理节点广播RREQ消息，周围的节点接收该RREQ消息。周围的节点可以继续广播该RREQ消息，知道逻辑节点接收到该RREQ消息。收到该RREQ消息的逻辑节点针对该RREQ消息进行反馈响应。
图7为本申请另一个实施例的建立路径的通信方法的示意性流程图。图7所示的通信方法包括S710至S760。其中，第二设备为路径的源节点，第一设备为路径的中转节点，第三设备为路径的目的节点。
S710，第一设备发送RREQ消息。
第一设备可以通过广播的方式发送RREQ消息。
S720，第二设备接收该RREQ消息，并发送该RREQ消息对应的第一RREP消息。
第二设备可以通过广播的方式发送第一RREP消息。
可选地，第一RREP消息中可以携带标识第二设备的信息。
S730，第三设备接收该RREQ消息，并发送该RREQ消息对应的第二RREP消息。
第三设备可以通过广播的方式发送第二RREP消息。
可选地，第二RREP消息中可以携带标识第三设备的信息。
S740，第一设备接收第一RREP消息和第二RREP消息，向发送路径标识信息。
其中，第一设备接收第一RREP消息和第二RREP消息之后，可以先根据这两个RREP消息中携带的标识设备的信息确定这两个RREP是否来自不同的设备。如果来自不同的设备，才发送路径标识信息。
其中，第一RREP消息每经过一个设备，可以在该第一RREP消息中记录该设备的信息；同样地，第二RREP消息每经过一个设备，可以在该第二RREP消息中记录该设备的信息。这样，第一设备在发送路径标识信息时，可以在发送路径标识信息的消息中携带第一RREP消息和第二RREP消息所经过的设备的信息，以便于这些设备接收到路径标识信息时，存储该路径标识信息。
S750，第二设备接收路径标识信息，并保存路径标识信息。
S760，第三设备接收路径标识信息，并保存路径标识信息。
图5至图7任意一个所示的方法中，可选地，第二设备和第三设备可以为逻辑节点，第一设备为物理节点。以图13所示的网络架构为例，在一个示例中，第二设备为节点D，第一设备为节点E，第三设备为节点F，即建立的路径为：从节点D开始，经过节点E，到达节点F；在另一个示例中，第二设备为节点D，第一设备包括节点B、节点A和节点C，第三设备为节点G，即建立的路径为：从节点D开始，经过节点B、节点A和节点C，到达节点G。
可选地，第二设备和第三设备中的一个或两个为物理节点，例如，第二设备为节点B， 第一设备为节点F，第三设备为节点C，即建立的路径为：从节点B开始经过节点F到达节点C；又如，第二设备为节点E，第一设备为节点F，第三设备为节点A，即建立的路径为：从节点E开始经过节点F到达节点A；又如，第二设备为节点F、第一设备为节点B，第三设备为节点E，即建立的路径为：从节点F开始经过节点B到达节点E。
可以理解的是，第二设备与第三设备之间可以存在更多的第一设备，也就是说，源节点与目的节点之间可以存在多个中转节点，例如路径“节点F-节点B-节点E-节点D”上存在中转节点B和E；或者，第二设备与第三设备之间可以没有第一设备，也就是说，源节点与目的节点之间可以没有中转节点，例如，节点F与节点G之间的虚线表示的路径上没有中转节点。
本申请另一个实施例中，可以包括上述三种路径建立方法中的任意两种方法，或者可以包括上述三种路径建立方法。
下面结合图2至图4介绍本申请进行信息传输的一种通信方法。应理解，图2至图4中任意图示出的步骤或操作仅是示例，本申请提出的技术方案还可以执行其他操作或者图2至图4中任意图中的各个操作的变形。
图2所示的通信方法可以包括S210和S220。其中的第二设备可以是接入网设备、中继设备或终端设备。可以理解的是，本实施例中的第二设备可以是图5至图7任一图所示方法中的第二设备，也可以是其他设备。
S210，第二设备确定第一信息，第一信息中包括控制信息和数据信息，所述控制信息用于指示传输所述数据信息的资源，所述控制信息携带第一路径标识信息，第一路径标识信息用于标识所述第一信息的目标路径。
本申请实施例中，目标路径是指第一信息从第一信息的源节点传输至第一信息的目的节点的过程中经过的路径。该目标路径可以是第一信息的源节点传输至第一信息的目的节点的完整路径，也可以是第一信息的源节点传输至第一信息的目的节点的完整路径中的一段路径。
在一些可能的实现方式中，目标路径建立在两个逻辑节点之间。这两个逻辑节点中的一个逻辑节点称为该目标路径的源节点，另一个逻辑节点可以称为该目标路径的目的节点。
例如，以图14所示的网络架构为例，节点D与节点F之间建立了从节点D开始经过节点E到达节点F的路径，节点F与节点A之间建立了从节点F开始经过节点B到达节点A的路径，节点A与节点G之间建立了从节点A开始经过节点C到达节点G的路径。图14中，虚线圈表示物理节点，实线圈表示逻辑节点。
这种实现方式中，第二设备可以是该目标路径的源节点，例如，以图14所示的网络架构为例，目标路径为从节点D开始经过节点E达到节点F的路径时，第二设备为节点D；或者，第二设备可以是该目标路径上除了源节点和目的节点以外的节点，例如，目标路径为从节点D开始经过节点E到达节点F的路径时，第二设备为节点E。
这种实现方式中，第二设备可以根据第一信息的目的节点确定第一信息。下面以图14所示的网络架构为例，介绍目标路径为两个逻辑节点之间的路径的场景下，第二设备根据第一信息的目的节点确定第一信息的实现方式。
例如，第二设备为节点D或节点E，第一信息的目的节点为节点F时，第二设备可以 生成第一信息，该第一信息中的控制信息携带从节点D经过节点E到达节点F的目标路径的路径标识信息。作为逻辑节点的节点F接收到第一信息之后，可以通过较高层获知第一信息的目的节点的信息，比如通过较高层从第一信息的数据信息中获知第一信息的目的节点的信息，并根据该信息确定自己为第一信息的目的节点，从而停止第一信息的转发。
又如，第二设备为节点D或节点E，第一信息的目的节点为节点B时，第二设备根据其上的路由表得知可以经过节点F到达节点B，从而第二设备可以生成第一信息，该第一信息中的控制信息携带从节点D经过节点E到达节点F的目标路径的路径标识信息。作为逻辑节点的节点F接收到第一信息之后，可以通过较高层获知第一信息的目的节点的信息，比如通过较高层从第一信息的数据信息中获知第一信息的目的节点的信息，并根据该信息确定自己不是第一信息的目的节点。并且，节点F可以生成新的第一信息，新的第一信息中包括新的控制信息和原第一信息中的数据信息，新的控制信息携带从节点F经过节点B到达节点A的目标路径的路径标识信息，以及携带目的节点标识信息，该目的节点标识信息用于标识节点B。这样，节点B接收到新的第一信息之后，可以根据该第一信息中的路径标识信息判断自己为目标路径上的节点，即，通过物理层获知第一信息的路径标识信息，根据该第一信息中的目的节点标识信息判断是否为第一信息的目的节点，即，通过物理层获知第一信息的目的节点标识信息，从而停止转发该第一信息。所述控制信息携带目的节点标识信息的方式可以参考前述发送节点通过控制信息携带目的节点标识信息的方式，此处不再赘述。
在另一些可能的实现方式中，目标路径建立在任意两个节点之间，例如建立在两个物理节点之间，或者建立在一个物理节点和一个逻辑节点之间。
以图14所示的网络架构为例，目标路径可以是从节点E经过节点F到达节点B的路径；或者，目标路径可以是从节点E经过节点F和节点B到达节点A的路径；或者目标路径可以是从节点F经过节点B和节点A到达节点C的路径。
这种实现方式中，第二设备可以根据第一信息的目的节点确定第一信息。下面以图14所示的网络架构为例，介绍目标路径为两个逻辑节点之间的路径的场景下，第二设备根据第一信息的目的节点确定第一信息的实现方式。
例如，目标路径为从节点E经过节点F和节点B到达节点A的路径，且第二设备为节点F时，第二设备从节点E接收第一信息，该第一信息包括控制信息和数据信息，该控制信息中携带目标路径的路径标识信息和目的节点标识信息，该目的节点标识信息用于标识节点B；第二设备从第一信息中的数据信息中获取第一信息的目的节点信息，根据该目的节点信息确定自己不是目的节点，并转发该第一信息。所述控制信息携带目的节点标识信息的方式可以参考前述发送节点通过控制信息携带目的节点标识信息的方式，此处不再赘述。
S220，第二设备发送第一信息。
第二设备可以通过广播或者说组播的方式发送第一信息。以图14所示的网络为例，目标路径为从节点A经过节点到达节点F的路径时，作为第二设备的节点A可以通过广播的方式发送第一信息，该第一信息中携带该目标路径的路径标识信息。这种情况下，节点B和节点C都可以接收到第一信息，其中，节点B接收到第一信息后可以继续广播该第一信息，节点C接收到第一信息之后，不转发该第一信息。
本申请实施例中，第二设备在发送第一信息时，在控制信息中携带目标路径的路径标识信息，使得接收到第一信息的设备可以在物理层根据该路径标识信息确定自己是否为目标路径上的节点，以确定是否需要转发第一信息，从而可以节省时延。此外，还可以扩大网络的覆盖范围。
本申请实施例中，所述目标路径为从逻辑节点出发到达另一个逻辑节点的路径的场景下，第一信息的目的节点为物理节点，且第一信息的目的节点位于该目标路径上时，在控制信息中可以携带目的节点标识信息，使得目的节点可以在物理层可以根据该目的节点标识信息确定自己是否为目标路径的目的节点，以确定是转发第一信息还是进行其他处理，从而可以及时终止信息的转发，节省传输资源。
以图14所示的网络架构为例，目标路径为从节点D经过节点E到达节点F的路径时，若第一信息的目的节点为节点E，则节点D作为第二设备发送第一信息时，其中的控制信息携带目的节点标识信息，该目的节点标识信息指示节点E。节点E接收到节点D发送的第一信息时，根据目的节点标识指示节点E，可以确定自己为第一信息的目的节点，从而可以及时终止第一信息的转发，节省传输资源。
所述目标路径为从逻辑节点出发到达另一个逻辑节点的路径的场景下，若第一信息的目的节点没有位于所述目标路径上或者第一信息的目的节点为所述另一个逻辑节点，则该控制信息可以不携带目的节点标识信息，因为所述另一个逻辑节点可以在更高层获知自己是否为第一信息的目的节点。
以图14所示的网络架构为例，目标路径为从节点D经过节点E到达节点F的路径时，若第一信息的目的节点为节点B，则节点E作为第二设备发送第一信息时，其中的控制信息可以不携带目的节点标识信息。这种情况下，节点E接收到节点D发送的第一信息之后，广播该第一信息，节点F接收到节点D广播的第一信息之后，在更高层根据数据信息获知第一信息的目的节点，根据第一信息的目的节点确定新的目标路径为从节点F开始经过节点B至节点A的路径，并根据第一信息生成第二信息，第二信息中包括第一信息中的控制信息和数据信息，只不过该控制信息携带的第一路径标识信息标识的是新的目标路径，且该控制信息携带目的节点标识信息，该目的节点标识信息用于标识节点B。
本申请实施例中，可选地，所述控制信息还可以携带数据标识信息，该数据标识信息用于标识所述控制信息，或者说用于标识所述第一信息。这样，接收到所述第一信息的设备可以根据该数据标识信息确定之前是否转发过所述第一信息，以确定是否转发第一信息，从而可以避免信息的重复传输，进而节省传输资源。
以图14所示的网络架构为例，节点B接收节点F发送的第一信息并转发给节点A后，节点A不是第一信息的目的节点的情况下，节点A会广播该第一信息。作为邻接节点的节点B也会接收到节点A发送的第一信息。此时，节点B可以根据第一信息中的数据标识信息判断自己已经转发过该第一信息，不再需要继续转发该第一信息，从而节省传输资源。
所述控制信息携带数据标识信息的方式可以参考前述发送节点通过控制信息携带数据标识信息的方式，此处不再赘述。
图3所示的通信方法可以包括S310和S320。其中的第一设备可以是接入网设备、中继设备或终端设备。
S310，第一设备接收第一信息，第一信息中包括控制信息和数据信息，所述控制信息用于指示传输所述数据信息的资源，所述控制信息携带第一路径标识信息，第一路径标识信息用于标识所述第一信息的目标路径。
该步骤中的相关内容可以参考S210中的相关内容，此处不再赘述。
S320，第一设备根据所述控制信息确定第一预设条件得到满足时发送第二信息，第一预设条件包括：第一设备存储的路径标识信息包括第一路径标识信息，第一设备存储的路径标识信息为第一设备所在路径的标识信息。
应说明的是，第一设备发送第二信息的一种实现方式包括：第一设备将第一信息中的控制信息和/或数据信息继续转发下去；另一种实现方式包括：第一设备对第一信息中的控制信息/或数据信息进行处理后，生成第二信息，然后通过第二信息转发第一信息中的控制信息和/或数据信息。此处所说的处理包括：第一设备对所述第一信息进行译码，并对译码后的信息进行重新编码，生成第二信息；或，包括：第一设备计算所述第一信息的软信息，并根据该软信息生成第二信息。
可选的，所述第一信息包括路由所述第一信息中的控制信息和/或数据信息的目的地址，这样，第一设备可以在物理层之上的更高层获取所述目的地址，进而确定该第一设备不是目的节点，从而确定发送第二信息。这种方式，适用于第一设备为逻辑节点的情况。
可选的，所述第一信息中的控制信息可以携带目的节点标识信息，这样，第一设备可以在物理层通过该目的节点标识信息确定该第一设备不是目的节点，从而确定发送第二信息。这种方式，既适用于第一设备为逻辑节点的情况，又适用于第一设备为物理节点的情况。第一设备为逻辑节点时，这种方式可以减少将信息传递到物理层之上的更高层进行处理的时间，减少传输时延，提高传输效率。
第一设备可以通过广播或者说组播的方式发送第二信息。以图14所述的网络架构为例，目标路径为从节点D经过节点E到达节点F的路径，且第一设备为节点E时，第一设备从节点D接收第一信息之后，根据第一信息中的控制信息判断上述第一预设条件得到满足，并广播或组播该第二信息。
可选地，所述第一预设条件不满足时，不发送所述第二信息。以图14所述的网络架构为例，目标路径为从节点A经过节点B到达节点F的路径，且第一设备为节点C时，第一设备从节点A接收第一信息之后，根据第一信息中的控制信息判断上述第一预设条件不满足，即第一设备上存储的路径标识信息不包括目标路径的路径标识信息，因此第一设备不转发第一信息。
第一设备根据所述控制信息确定第一设备存储的路径标识信息是否包括第一路径标识信息的方式，可以参考前述接收节点确定接收节点存储的路径标识信息是否包括目标路径的路径标识信息的相关内容，此处不再赘述。
第一设备存储的路径标识信息可以是一个或多个，每个路径标识信息标识第一设备所处的网络中的一条路径。
第一设备在物理层根据该路径标识信息确定自己是否为目标路径上的节点，以确定是否需要转发第一信息，从而可以节省时延。此外，还可以扩大网络的覆盖范围。
可选地，所述控制信息还可以携带目的节点标识信息，这样，第一设备可以在物理层根据该目的节点标识信息确定自己是否为目标路径的目的节点，以确定是转发第一信息还 是进行其他处理，从而可以及时终止信息的转发，节省传输资源。
以图14所述的网络架构为例，第一信息的目的节点为节点B，目标路径为从节点F经过节点B到达节点A的路径，节点F发送第一信息时，可以在第一信息的控制信息中携带目标路径的第一路径标识信息和第一信息的目的节点标识信息，该目的节点标识信息用于标识节点B，这样，节点B(第一设备)从节点F接收第一信息之后，根据第一信息中的控制信息判断自己存储的路径标识信息包括目标路径的路径标识信息，且自己为目的节点标识信息所标识的节点，并停止转发该第一信息。
第一设备从所述控制信息获取目的节点标识信息的方式可以参考前述接收节点获取控制信息携带的目的节点标识信息的方式，此处不再赘述。
可选地，所述控制信息还可以携带数据标识信息，该数据标识信息用于标识所述控制信息，或者说用于标识所述第一信息。这种情况下，所述第一设备可以根据该数据标识信息确定之前是否转发过所述第一信息，以确定是否转发第一信息，从而可以避免信息的重复传输，进而节省传输资源。
第一设备从所述控制信息获取数据标识信息的方式可以参考前述接收节点获取控制信息携带的数据标识信息的方式，此处不再赘述。
图4为本申请另一个实施例的通信方法的示意性流程图。图4所示的通信方法可以包括S410和S420。其中的目标设备可以是接入网设备、中继设备或终端设备。
S410，目标设备接收第三信息，所述第三信息包括控制信息和数据信息，所述控制信息指示用于传输所述数据信息的资源，所述控制信息携带第一路径标识信息，所述第一路径标识信息用于标识所述第三信息的目标路径。
此处所述的第三信息可以是S220中的第一信息，也可以是S320中的第二信息。
S420，目标设备根据第三信息确定第二预设条件得到满足时，确定不发送所述第三信息，第二预设条件包括：目标设备上存储的路径标识信息包括第一路径标识信息，目标设备为所述目标路径的目的节点。
目标设备根据所述控制信息确定目标设备存储的路径标识信息是否包括第一路径标识信息的方式，可以参考前述接收节点确定接收节点存储的路径标识信息是否包括目标路径的路径标识信息的相关内容，此处不再赘述。
目标设备存储的路径标识信息可以是一个或多个，每个路径标识信息标识目标设备所处的网络中的一条路径。
目标设备在物理层根据该路径标识信息确定自己是否为目标路径上的节点，以确定是否需要转发第一信息，从而可以节省时延。此外，还可以扩大网络的覆盖范围。
可选的，所述第三信息包括路由所述第一信息中的控制信息和/或数据信息的目的地址，这样，目标设备可以在物理层之上的更高层获取所述目的地址，进而确定该目标设备不是目的节点，从而确定不发送第三信息。这种方式，适用于目标设备为逻辑节点的情况。由于目标设备通常需要将控制信息和/或数据信息传递到物理层之上的更高层进行处理，因而这种方式较普遍。
可选的，所述第三信息中的控制信息可以携带目的节点标识信息，这样，目标设备可以在物理层通过该目的节点标识信息确定该第一设备不是目的节点，从而确定不发送第三信息。这种方式，既适用于目标设备为逻辑节点的情况，又适用于目标设备为物理节点的 情况。第一设备为逻辑节点时，这种方式可以及时终止转发，减少传输时延，提高传输效率。目标设备不再继续往外发送第三信息中的数据信息和控制信息的情况下，目标设备可以通过物理层以上的更高层，例如层2或层3，获知数据信息中业务数据。
若控制信息还携带目标路径的目的节点标识信息，目标设备确定自己是否为目标路径的目的地节点的一种方式包括：确定自己是否为目的节点标识信息指示的节点，是则可以确定自己是目的节点，否则可以确定自己不是目的节点。
目标设备在物理层根据目的节点标识信息确定自己是否为目的节点，以确定是否需要转发第三信息，可以及时终止信息的转发，从而可以节省时延。此外，还可以扩大网络的覆盖范围。
若控制信息携带目标路径的数据标识信息，第二预设条件还可以包括：目标设备没有接收过所述数据标识信息所指示的信息。其中，目标设备可以根据该数据标识信息确定是否接收过该第三信息，以确定是否需要对该数据进行处理。例如，目标设备是目标路径上的节点、且是目的节点且没有接收过该信息时，可以将该信息送到更高层处理。
目标设备可以根据该数据标识信息确定之前是否接收过所述第三信息，以确定是否需要继续处理第三信息，从而可以进而节省网络资源。
