具体实施方式
为了使本申请的目的、技术方案和优点更加清楚，下面将结合附图对本申请作进一步地详细描述。方法实施例中的具体操作方法也可以应用于设备实施例或系统实施例中。其中，在本申请的描述中，除非另有说明，“多个”的含义是两个或两个以上。
图1为本申请实施例适用的一种系统架构图，如图1所示，该系统架构包括：主机(控制节点)、与控制节点连接的传输系统。其中，传输系统中可以包括一个或多个传输节点，一个或多个传输节点中包括主节点(Master)，除主节点以外的其它传输节点可以称为从节点(Slave)。示例性地，传输节点也可以称为传输设备，主节点也可以称为主设备，从节点可以称为从设备。可选的，传输设备还可以连接一个或多个外围设备，其中，外围设备也可以称为外围器件、外接器件外接设备或外设。可以理解的，该系统架构图可以是车载通信系统的架构，也可以是用于其它场景的系统架构，本申请各实施例对此不作限制。下面对上述各个设备进行解释说明，以便于本领域技术人员理解。
主机(控制节点)：可以用于配置传输系统中的各传输节点的通信方式。例如，控制节点可以对传输系统中的传输设备配置用于指示接收、解调、转发、填充等操作的配置信息，以指示传输设备完成上述中的部分或全部操作，进一步还可以实现多个传输设备之间的通信交互。此外，控制节点还可以实现其他功能，这里不再一一列举。示例性地，控制节点中可以包括处理器，处理器可以是一个通用中央处理器(central processing unit，CPU)、微处理器、特定应用集成电路(application-specific integrated circuit，ASIC)或一个或多个用于控制本申请方案程序执行的集成电路。
主节点：也可以称为主传输节点，主节点可以接收控制节点发送的数据，并将控制节点发送的数据进行封装后传输给各个从节点，还可以接收各个从节点发送的数据，并将各个从节点发送的数据进行解封装后发送给控制节点。如果主节点连接了外围设备，还可以与外围设备之间传输数据，如获取外围设备采集的数据、向外围设备发送数据。主节点还可以将该主节点连接的外围设备采集的数据进行封装后发送给控制节点，还可以将控制节点发送的数据进行解封装后发送给连接的外围设备。此外，主节点还可以实现其他功能，这里不再一一列举。在本申请各实施例中，相对于主机(控制节点)，主节点也可以称为 从属节点。
从节点：也可以称为从传输节点，从节点可以获取外围设备采集的数据并发送给主节点，还可以将主节点或其他从节点发送的数据发送给连接的外围设备。若从节点为菊花链中的中间节点，则从节点还可以将下级从节点发送的数据转发给主节点，或者将主节点发送的数据转发给下级从节点。此外，从节点还可以实现其他功能，这里不再一一列举。在本申请各实施例中，相对于主机(控制节点)，从节点也可以称为从属节点。
外围设备：可以包括以下至少一项：麦克风、毫米波雷达、激光雷达、超声波雷达、摄像头、定位系统、惯性传感器、速度传感器、加速度传感器、湿度传感器、光强度传感器，还可以包括播放设备，如显示屏、外置功放、扬声器等。在其它可能的实施例中，外围设备还可以包括其它可能的设备，此处不再一一列举。
需要说明的是：(1)本申请实施例中涉及的控制节点(主机)、从属节点(主节点、从节点)等网元可以是逻辑概念或者也可以实体概念。比如，控制节点、主节点、从节点等网元的形态可以是实体设备；进一步地，多个网元可以分别是多个实体设备，或者也可以是多个网元集合成一个实体设备，例如从节点1和从节点2可能在一个电路板上。又比如，控制节点(主机)、从属节点(主节点、从节点)等网元的形态也可以是一块电路板或电路板上的一个芯片或一个芯片区域所实现的功能。(2)图1所描述的系统架构可以适用于多种可能的场景，比如可以适用于车内音频系统。当上述系统架构应用于车内音频系统时，控制节点可以为主机(Host)，例如数字信号处理(Digital Signal Process，DSP)设备，外围设备可以包括麦克风阵列(MIC array)、扬声器(SPK)等。
基于图1所示意的系统架构，以系统架构中包括N个从节点，N为大于或等于1的整数。N个从节点可以分别为从节点0、从节点1、从节点2、……、从节点N-1；其中，0、1、2、……、N-1可以理解为从节点分配的编号。本申请实施例中，也可以为主节点分配编号，比如为主节点分配的编号为N。需要说明的是，为主节点和从节点编号可以有多种可能的实现，比如若为从节点分配的起始编号为1，则为主节点分配的编号也可以为0。示例性地，当传输系统中所包括的节点个数较多时，多个节点之间的连接可以构成多种可能的拓扑结构，比如菊花链拓扑结构，参见图2所示；又比如环形拓扑结构，采用图3所示；又比如树形拓扑结构。
参见图4，以N＝4为例，描述本申请实施例所适用的一种可能的系统架构，该系统架构可以适用于车内音频系统，参见图4所示，主机与主节点、主节点与从节点、从节点与从节点之间以菊花链拓扑结构进行连接，其中，从节点0可以理解为从节点1的上级节点，相应地，从节点1可以理解为从节点0的下级节点；从节点1可以理解为从节点2的上级节点，相应地，从节点2可以理解为从节点1的下级节点，以此类推。
示例性地，从节点0上外接有至少一个麦克风，从节点1和从节点2上分别外接有至少一个扬声器。以该系统架构为例，从节点0可以获取麦克风采集到的数据，并将获取到的该音频数据发送至主节点，主节点将该数据进行解封装后发送给主机，主机可以用于对麦克风等外围设备传输的数据进行处理，如对麦克风采集的语音数据进行滤波、降噪等处理。主节点可以用于将经过主机处理的数据封装后发送到各个从设备，例如，将主机进行降噪处理后的语音数据进行封装后发送至主节点，由主节点转发至从节点0，再由从节点0转发至从节点1，从节点1将该音频数据发送至扬声器，以此进行播放。也就是说，音频等下行数据流可以由主机发送给主节点，进而由主节点发送给各个从节点，再由从节点 传输给外围设备，其传输路径可描述为Host→Master→Slave0→Slave1→Slave2。音频等上行数据流由麦克风采集传输给从节点，由从节点发送到主节点，再由主节点中转给Host，传输的路径可描述为Slave2→Slave1→Slave0→Master→Host。由于业务不同，外围设备往往也具有不同的采样频率，传输节点需要时时监听可能产生的业务数据，由此导致了较多的能量损耗，目前，如何配置适配于上述多业务混合传输需求的通信方案是需要被解决的问题。
鉴于此，本申请实施例提供一种通信方法，用于实现适配于电子设备自身业务需求的数据传输方法，下面以图4所示的系统架构为例，对本申请技术方案进行具体说明。
本申请实施例中，如无特殊说明，控制节点指的是图1中的主机(在描述方案时，两者可以互换)，从属节点可以是图1中的主节点，或者从节点。
本申请中的控制节点、第一从属节点可以分别是图1～图4所示的主机、传输节点(主节点，或者从节点)，也可以是未来通信系统中的具有上述主机、传输节点的功能的网元。
需要说明的是，本申请实施例中的第二从属节点代指第一从属节点的上级节点，即第二从属节点可以包含一个或多个传输节点，例如，第一从属节点为从节点1时，第二从属节点可以是从节点0，也可以是主节点和从节点0。另外，第三从属节点为第一从属节点的下级节点，即第三从属节点可以包含一个或多个从节点，例如，第一从属节点为从节点0，第三从属节点可以是图4中的从节点1，也可以是从节点1和从节点2。
本申请实施例提供的通信方法中，主机可以为传输节点配置第一配置信息，其中，第一配置信息属于配置信息集合，该配置信息集合包含至少一个配置信息，该配置信息集合包含的每个第一配置信息用于指示该传输节点在预设时间周期的部分或全部时间单元上，是否执行该第一配置信息对应的操作；主机将该配置信息集合中的任一第一配置信息发送给该传输节点。对应的，传输节点接收来自主机的第一配置信息，并根据该第一配置信息确定在预设时间周期内的部分或全部时间单元上是否需要执行该第一配置信息对应的操作。进一步，该配置信息集合可以包含多个第一配置信息(不同的第一配置信息对应的操作不同)，则传输节点可以联合该多个第一配置信息共同确定，在预设时间周期内的各时间单元上是否需要执行该多个第一配置信息对应的多个操作。采用该方法，主机能够为每一个具有不同采样频率的传输节点配置相应的第一配置信息，各第一配置信息组成配置信息集合，各传输节点按照主机为其配置的配置信息集合判断是否需要执行对应的操作，完成可预期或不可预期的数据传输需求，适配于电子设备自身业务需求，且满足存在多种业务需求的传输系统对于各电子设备的数据传输的协调和管理，实现主机对传输系统内的各传输节点的灵活配置。
首先对预设时间周期进行介绍。
本申请实施例中，一个预设时间周期可以包括下行时域资源和/或上行时域资源，其中的部分或全部时域资源可以按照时间单元进行划分，示例性地，时间单元包括但不限于，无线帧、子帧、时隙、迷你时隙、符号、秒、毫米、微秒等，本申请对此不作限定。具体的，预设时间周期包含的时间单元的数量可以是预设的，或者是协议约定的，或者其他方式确定的，本申请实施例对此不作限定。
一种可能的实现方式中，预设时间周期包含下行时域资源和上行时域资源，其中，预设时间周期内下行时域资源和上行时域资源的位置没有限定，例如，可以是下行时域资源在上行时域资源之前，也可以是上行时域资源在下行时域资源之前，本申请实施例对此不 作限定，优选地，本申请实施例中预设时间周期内下行时域资源在前，上行时域资源在后。另外，下行时域资源和上行时域资源分别包含的时间单元的数量可以相同也可以不同，例如，时间单元为时隙，下行时域资源中可以包含8个时隙，上行时域资源中可以包含6个时隙，本申请实施例对此不作限定。
下面以预设时间周期包含下行时域资源和上行时域资源，时间单元为时隙为例，对预设时间周期进行具体介绍。请参考图5，为本申请实施例提供的一种预设时间周期的结构示意图，如图5所示，该预设时间周期按照排列顺序包括下行时域资源和上行时域资源，其中，下行时域资源可以包括但不限于：承载下行导频的时域资源、承载下行帧头的时域资源以及下行时隙1至下行时隙n，其中，该下行时域可以用于承载图4中的各传输节点的规律性数据，因此，该下行时隙也可以称为下行规律时隙。同样的，上行时域资源可以包括但不限于：承载上行导频的时域资源、承载上行帧头的时域资源以及上行规律时隙1至上行规律时隙k，其中，n与k可以相等也可以不等。
具体的，下行时域资源用于承载下行信息，上行时域资源用于承载上行信息。
示例性地，在图4所示的系统架构中，在一个预设时间周期中，下行信息的传输过程为：Host→Master→Slave0→Slave1→Slave2，具体的，各节点依次将导频信号、帧头、以及分别将下行规律时隙1～n承载的数据发送至自身的下级节点。上行信息的传输流程可以是：Slave2→Slave1→Slave0→Master→Host，具体的，各节点依次将导频信号、帧头、以及分别将上行规律时隙1～k承载的数据发送至自身的上级节点。
下面对图5所示的预设时间周期包含的部分进行详细介绍：
(1)导频：导频信号可以用于相邻的两两节点之间进行时间同步，即主机与主节点，主节点与从节点，从节点与从节点之间进行时间同步。
应理解地是，本申请实施例中的系统架构中各相邻两个节点之间的时间是同步的。例如，主节点在预设时间周期的slot1向从节点0发送数据a，对应的，从节点0也应该在该预设时间周期的slot1接收数据a，因此，两相邻节点之间的时间应是同步的。若两相邻节点之间时间不同步，则可能产生丢包问题。
示例性地，导频信号可以是预设字符串，例如10011100，两节点之间通过导频信号保持节拍一致，即时间同步。
(2)帧头，包括但不限于帧号或其他信息。
其中，帧号可以是预设时间周期的标识，示例性地，预设时间周期为周期性的循环周期，假设预设时间周期的帧号按照0～1023进行循环编号。其中，同一预设时间周期中的下行帧头和上行帧头中的帧号可以相同，传输节点可以根据帧号确定当前时间周期的标识。
示例性地，导频和帧头可以是具有固定长度的字符串，例如，导频信号为10bit的字符串，帧头为100bit的字符串，传输节点可以根据导频信号的预设字符串确定帧头的位置，并根据帧头的预设的数据大小确定下行规律时隙的起始时间。
(3)规律时隙，用于承载规律性数据，例如，外围设备周期性采集的音频信号。
举例来说，从节点0外接有麦克风，该麦克风按照固定频率周期性采集音频数据，从节点0可以将该音频数据发送至主机，则主机可以为从节点0配置预设时间周期中的一个或多个上行规律时隙，以指示从节点0通过该一个或多个上行规律时隙传输该音频数据，应理解，该音频数据的目的端为主机，该音频数据经从节点0发出后，需要经过主节点发送至主机(上述举例称为示例1)。
或者，从节点1连接有扬声器，从节点0还可以将该音频数据发送至从节点1，通过从节点1的扬声器进行外放，则主机可以为从节点0配置预设时间周期中的一个或多个下行规律时隙，以指示从节点0将该音频数据发送至从节点1，并指示从节点1接收该一个或多个下行规律时隙承载的音频数据(上述举例称为示例2)。
上述示例1和示例2中的通信方式可以通过第一配置信息来配置，下面对第一配置信息进行具体介绍。
本申请实施例中，第一配置信息可以用于配置预设时间周期中的部分或全部时间单元，主机通过第一配置信息指示传输节点在该部分或全部时间单元中的任一时间单元是否执行该第一配置信息对应的操作，可以理解地，不同的第一配置信息对应不同的操作。也就是，第一配置信息可以指示两方面：(1)时间单元，(2)对该时间单元的操作。
具体的，第一配置信息可以以预设时间周期中的时间单元为粒度进行配置。例如，第一配置信息为比特位图，该比特位图中的每个比特位分别用于指示一个时间单元。其中，该比特位图与预设时间周期中的部分或全部时间单元的对应关系可以是预设的或者协议约定的，或者是其他方式确定的，例如，比特位图与预设时间周期中的部分或全部时间单元，均按照从左至右的顺序一一对应。
换而言之，比特位图中左起第一个比特位用于指示预设时间周期中的部分或全部时间单元中的左起第一个时间单元，比特位图中左起第二个比特位用于指示该预设时间周期中的部分或全部时间单元的左起第二个时间单元，以此类推。
例如，预设时间周期中包含下行规律时隙1至下行规律时隙8，对应的，用于指示下行规律时隙的第一配置信息对应的比特位图也包括8个比特位，则该比特位中的左起第一个比特位对应于下行规律时隙1，左起第二比特位对应于下行规律时隙2，左起第三个比特位对应于下行规律时隙3，以此类推。
需要说明的是上述仅为举例，比特位图中的比特位与时间单元还可以是其他对应关系，此处不再一一举例。为方便描述，下文中关于比特位图中的比特位与预设时间周期中的各时间单元均按照从左至右的顺序一一对应，下文不再重复说明。
示例性地，比特位图中的比特位的取值，可以用于指示该比特位对应的时间单元是否执行该第一配置信息对应的操作，例如，若比特位的值为1，则表示需要执行该第一配置信息对应的操作，若比特位的值为0，则表示不需要执行该第一配置信息对应的操作。需要说明的是，上述仅为举例，还可以是比特位的值为0，表示需要执行第一配置信息对应的操作，比特位的值为1，表示不需要执行第一配置信息对应的操作。本申请实施例对此不作限定。
下面对不同的第一配置信息对应的操作进行详细介绍，本申请实施例中第一配置信息包括但不限于下列配置信息：
下行时间单元激活信息、下行时间单元解调信息、下行时间单元转发信息、下行时间单元填充信息、上行时间单元激活信息、上行时间单元解调信息、上行时间单元转发信息、上行时间单元填充信息。
(1)下行时间单元激活信息，该配置信息对应的操作为激活操作，用于指示预设时间周期中的下行时间单元是否需要激活。这里的激活可以是指接收，即传输节点接收需要激活的时间单元所承载的数据，在一种场景中，该激活还可以是指可以被使用的，例如，传输节点可以根据激活的时间单元判断可以用于填充数据的时间单元，下文相似的描述不 再重复说明。
对于不需要激活的时间单元，则该传输节点不需要接收该时间单元承载的数据，如此一来，传输节点不需要持续监听每个时间单元，减少了能耗。
(2)下行时间单元解调信息，该配置信息对应的操作为解调操作，用于指示对预设时间周期中的下行时间单元是否需要执行解调(或者说解码)操作。如果需要，则传输节点对需要执行解调操作的时间单元所承载的数据进行解调。
可以理解地，传输节点对该时间单元所承载的数据进行解调前，需要先接收该时间单元所承载的数据。也就是说，主机可以通过多个用于指示不同操作的第一配置信息联合指示对同一时间单元的多个操作。例如，通过下行时间单元激活信息指示传输节点首先对该时间单元进行激活(接收)操作，然后通过下行时间单元解调信息指示该传输节点对激活的时间单元上接收的数据进行解调操作。
(3)下行时间单元转发信息，该配置信息对应的操作为转发操作，用于指示对预设时间周期中的下行时间单元是否需要执行转发操作，对于需要执行转发操作的时间单元，传输节点将该时间单元所承载的数据转发至下级节点。
同样的，在执行转发操作前，传输节点需要接收该时间单元所承载的数据，也就是说，主机通过下行时间单元激活信息和下行时间单元转发信息联合指示数据的转发过程。
(4)下行时间单元填充信息，该信息对应的操作为数据填充(或者说添加)操作，用于指示对于预设时间周期中的下行时间单元是否可以执行填充操作，或者指示可以执行填充操作的下行时间单元。对于可以执行填充操作的时间单元，传输节点可以将自身的数据填充至该时间单元，并将填充的数据转发至下级节点。
如前所述，下行时间单元填充信息，可以通过比特位图来指示时间单元，例如，下行规律时隙的编号为slot1～slot8，则下行时间单元填充信息可以是11001010，假设1表示可以进行填充，0表示不可以进行填充，则上述配置信息表示slot1、slot2、slot5和slot7可以进行填充。
示例性地，还可以通过其他方式来指示可以用于数据填充的时间单元。例如，预设可以进行填充的时间单元的位置，通过下行时间单元填充信息来指示可以用于填充的时间单元的数量，以此指示哪些时间单元可以进行填充。
举例来说，可以进行填充的时间单元的预设位置为转发操作的时间单元之后，下行时间单元填充信息可以是包含1个或多个比特位的字符串。示例性地，该字符串的取值用于指示可以用于数据填充的时间单元的数量，该时间单元位于转发操作的时间单元之后的空闲的时间，以保持数据帧的连续性。
例如，若转发操作的时间单元为slot1、slot2、slot5～slot7，则位于转发操作的时间单元之后的空闲的时间单元为slot3、slot4和slot8，若下行时间单元填充信息对应的字符串的取值为1个，例如，下行时间单元填充信息可以是00000001，即可以用于数据填充的下行时间单元的数量为1，对应的，该1个用于填充的时间单元位于转发操作之后，则该1个时间单元可以是slot3或slot4或slot8，若可以用于数据填充的时间单元的数量为2个，则下行时间单元填充信息还可以是00000010，对应的，该2个时间单元可以是slot3和slot4，或slot3和slot8，或slot4和slot8，以此类推。为了保持下行信息的连续性，使下行信息之间尽量没有空隙，优选地，该2个时间单元可以是slot3和slot4。
再示例性地，还可以通过下行时间单元填充信息对应的字符串中预设比特值的比特位 的数量来指示可以进行填充的时间单元的数量。同样的，该时间单元可以为位于转发操作的时间单元之后的空闲的时间。
例如，该字符串中比特值为预设值(例如为1)的比特的数量表示可以用于数据填充的时间单元的数量，取值为预设值的比特的位置在字符串中的位置可以是任意的。例如，可以进行填充的时间单元的数量为1时，则下行时间单元配置信息可以是10000000或01000000或00000010等；可以进行填充的时间单元的数量为2时，则下行时间单元配置信息可以是11000000或01100000或00000011等，此处不再一一枚举。
需要说明的是，对于填充操作，传输节点可以将自身采集到的数据添加至下行时间单元内并转发至下级节点，即填充操作也可以实现转发操作的功能，传输节点还可以将从上级节点接收到的数据填充至时间单元，例如，该传输节点具备数据处理功能时，可以将从上级节点接收到的数据进行处理后，通过填充操作发送给下级节点，对于从上级节点接收到的数据，传输节点需要首先将接收到的数据进行解调，然后将解调后的数据填充至对应的时间单元内。相较于转发操作，传输节点不需要对从上级节点接收到的数据进行解调，因此，转发操作更适用于对于时延要求较高的数据的传输。
其中，上行时间单元激活信息、上行时间单元解调信息、上行时间单元转发信息和上行时间单元填充信息用于指示上行时间单元，对于上述配置信息对应的操作可以分别参见上述下行时间单元激活信息、下行时间单元解调信息、下行时间单元转发信息和下行时间单元填充信息的具体介绍，此处不再赘述。
本申请实施例中主机可以为传输节点配置一个或多个上述第一配置信息，该一个或多个第一配置信息组成一个配置信息集合。需要说明的是，配置信息集合中，用于配置预设时间周期中相同部分的时间单元的多个第一配置信息，各第一配置信息中相同位置的比特位对应同一预设时间周期上的同一时间单元。
如表1所示，为主机为一个传输节点配置的配置信息集合的一具体示例。在该示例中，假设下行规律时隙和上行规律时隙均为8个，假设下行规律时隙的编号为slot1～slot8，上行规律时隙的编号为slot9～slot16。第一配置信息均为包含8个比特位的比特位图，且每个比特位上的比特的值为1时表示需要执行该第一配置信息对应的操作，比特位上的比特的值为0表示不需要执行该第一配置信息对应的操作。

下面以表1和用于指示下行时间单元的各配置信息为例，对该传输节点根据第一配置信息进行下行数据传输的过程进行描述。
示例性地，下行时间单元激活信息、下行时间单元解调信息、下行时间单元转发信息和下行时间单元填充信息中的(左起)第1个比特位均对应于slot1，其中，下行时间单元激活信息的第1个比特位上的比特的值为1，表示接收slot1承载的下行数据；下行时间单元解调信息的第1个比特位上的比特的值为1，表示对slot1承载的下行数据进行解调；下行时间单元转发信息的第1个比特位上的比特的值为1，表示对slot1承载的下行数据进行转发，下行时间单元填充信息的第1个比特位上的比特的值为0，表示slot1不可以执行填充操作。
综上，该传输节点在slot1需要执行的操作包括，接收操作、解调操作和转发操作，示例性地，对于slot1的数据传输过程可以是：该传输节点接收slot1承载的数据，将该slot1承载的数据转发至下级节点，同时对该slot1承载的数据进行解调。
对于slot2所需执行的操作，可以参见上述对于slot1的具体描述，此处不再重复说明。
对于slot3需要执行的操作，其确定过程包括：下行时间单元激活信息、下行时间单元解调信息、下行时间单元转发信息和下行时间单元填充信息中的(左起)第3个比特位均对应于slot3，其中，其中，下行时间单元激活信息的第3个比特位上的比特的值为1，表示接收slot3承载的下行数据；下行时间单元解调信息的第3个比特位上的比特的值为1，表示对slot3承载的下行数据进行解调；下行时间单元转发信息的第3个比特位上的比特的值为0，表示不需要对slot3承载的下行数据进行转发，下行时间单元填充信息的第3个比特位上的比特的值为1，表示在slot2进行填充操作。
综上，该传输节点在slot3执行的操作包括，接收操作和解调操作，示例性地，对于slot3的数据传输过程可以是：该传输节点接收slot3承载的数据，并对该slot3承载的数据进行解调，该传输节点还可以将自身的数据填充至slot3发送至下级节点。
对于该预设时间周期中其他slot所需执行的操作，可以参见上述对于slot1或slot3的具体描述，此处不再重复说明。
本申请实施例，主机可以通过上述方式为各传输节点配置第一配置信息，以指示该传输节点在预设时间周期的时间单元上的操作，以完成数据传输。
基于上述内容，下面结合实施例一至实施例三对本申请实施例提供的通信方法进行描述。在实施例一至实施例三中，将以一个主机(控制节点)，一个传输节点(从属节点)，该主机为该传输节点配置一个第一配置信息为例，对本申请提供的通信方法进行介绍。
【实施例一】
请参考图6，为本申请实施例提供的一种通信方法所对应的流程示意图，如图6所示，该流程包括：
步骤S601，主机确定第一配置信息；
具体的，第一配置信息属于配置信息集合，配置信息集合包含至少一个配置信息，第一配置信息用于指示传输节点在预设时间周期包含的部分或全部时间单元上是否执行第一配置信息对应的操作。
示例性地，主机可以根据各传输节点的业务传输需求，例如，该传输节点的外围设备 为周期性采样的音频设备，该音频设备采集的数据需要进行处理还是需要进行外放，来为该传输节点配置第一配置信息。具体的如，主机可以扫描各传输节点所连接的外围设备，并根据各传输节点自身或其连接的外围设备的设备类型与对应的数据传输需求确定该传输节点的一个或多个数据传输需求。在示例性地，各传输节点的数据传输需求或第一配置信息还可以是预设在主机内的。
步骤S602，主机将第一配置信息发送给该传输节点。
示例性地，配置信息集合包含一个第一配置信息时，主机将第一配置信息发送给该传输节点。再示例性地，配置信息集合包含多个第一配置信息时，主机将配置信息集合中包含的每个第一配置信息发送给该传输节点。
步骤S603，传输节点接收该第一配置信息；
示例性地，在图4所示的系统架构中，主机可以通过内部集成电路(inter integrated circuit，I 2C)总线与主节点连接，其中，I 2C(也可以写为I2C)。主节点可以与从节点连接，不同从节点之间可以逐级连接。其中，主节点与从节点之间以及从节点与从节点之间可以通过双绞线(twisted pair，TP)连接，或者也可以其它方式连接，如同轴线(coaxial)等，具体不做限定。示例性地，传输设备还可以通过一根或多根I2C总线与一个或多个外围设备相连。
因此，主机以及每个传输节点可以为I2C器件，不同的I2C器件具有不同的地址，另外I2C器件中可以包括多个寄存器。本申请实施例可以通过多个寄存器分别配置不同的第一配置信息，例如，地址位为7位的寄存器，上述多个对应不同操作的第一配置信息可以分别对应一个寄存器地址，例如0000001～0000110，各类型的第一配置信息分别对应其中一个地址，且各第一配置信息的地址不重复。例如，用于配置上行时间单元激活信息的寄存器的地址为0000001，用于配置上行时间单元解调信息的寄存器的地址为0000010，用于配置上行时间单元转发信息的寄存器的地址为0000011，用于配置上行时间单元填充信息的寄存器的地址为0000100，以此类推。
示例性地，主机通过I2C器件的地址、寄存器地址和各寄存器地址对应的字符串为各传输节点配置第一配置信息。再示例性地，主机还可以控制传输节点进行读操作和/或写操作，将第一配置信息对应的字符串写入该第一配置信息对应的各寄存器地址所对应的寄存器中。再示例性地，还可以采用在各传输节点中预设第一配置信息的方式，即在各传输节点的相应寄存器中写入对应的字符串的方式来配置第一配置信息，本申请实施例对此不作限定。
本申请实施例中的规律时间单元还可以根据传输系统中需要进行周期性传输的数据的数量来配置，并不限定预设时间周期中各时间单元的数量。
需要说明的是，上述8位寄存器地址可以对应8个时间单元，若预设时间周期中的下行时域资源或上行时域资源中分别包含的规律时间单元的数量少于8个，则可以该寄存器中的部分比特位，例如下行规律时间单元为5个，则可以使用该8位寄存器中左起连续的5个比特位来对应该5个下行规律时间单元，也可以使用该8位寄存器中右起连续的5个比特位来对应该5个下行规律时间单元，本申请实施例对此不作限定。
若预设时间周期中的下行时域资源或上行时域资源中分别包含的规律时间单元的数量大于8个，则可以使用多个8位寄存器组合配置同一第一配置信息，例如，下行规律时间单元包含16个slot，则可以使用2个8为寄存器共同配置用于指示下行时间单元的配置 信息，示例性地，其中1个寄存器的8个比特位为该第一配置信息的高8位，另一个寄存器的8个比特位为该第一配置信息的低8位。或者，还可以使用1个16位寄存器来配置，本申请实施例对此不作限定，即本申请实施例可以通过组合不同比特位数的寄存器来配置第一配置信息。
为了方便描述，下文以下行规律时间单元和上行规律时间单元均为8个slot为例，对第一配置信息与部分或全部时间单元的对应关系进行描述。
第一种可选的实施方式，第一配置信息可以用于配置预设时间周期中的全部时间单元，例如，预设时间周期仅包含下行时域资源(或仅包含上行时域资源)，则第一配置信息可以包含8个比特位，每个比特位分别对应预设时间周期中的一个下行规律时间单元(或上行规律时间单元)。又例如，预设时间周期包含下行时域资源和上行时域资源，则第一配置信息可以包含16个比特位，每个比特位分别对应预设时间周期中的一个下行规律时间单元或一个上行规律时间单元。
第二种可选的实施方式，第一配置信息可以用于配置预设时间周期中的部分时间单元。例如，预设时间周期包含下行时域资源和上行时域资源，则第一配置信息可以包含8个比特位，若该第一配置信息用于指示下行时域资源，则该8个比特位中的每个比特位对应于一个下行规律时间单元，或该第一配置信息用于指示上行时域资源，则该8个比特位中的每个比特位对应于一个上行规律时间单元。
步骤S604，传输节点根据第一配置信息确定在预设时间周期包含的部分或全部时间单元上的操作。
步骤S605，传输节点在时间单元到达时，执行确定的上述操作。
下面结合具体的示例对根据第一配置信息进行数据传输的流程进行介绍。
示例1：通过第一配置信息配置广播数据的传输；
以图4所示的系统架构和下行规律时间单元为例，假设下行规律时间单元为slot1至slot8，用于承载广播数据的时间单元可以是slot1至slot2，则对于广播数据的传输的配置可以是：
步骤11：主机为主节点配置用于进行广播数据传输的第一配置信息；
主机为主节点配置的第一配置信息包括但不限于：下行时间单元激活信息和下行时间单元填充信息；示例性地，下行时间单元激活信息可以是11XXXXXX(X表示不限定，可以是0也可以是1，可以根据数据传输需求配置，对此不作限定)，下行时间单元填充信息(比特位图)可以是11XXXXXX。对应的，从节点根据各第一配置信息确定，slot1和slot2为激活的时隙，并将需要传输的广播数据填充至slot1和slot2中。
上述仅为举例，下行时间单元填充信息还可以为用于表示可以用于填充的时间单元的数量的字符串，例如00000010，若下行时间单元填充信息为字符串时，则主节点可以根据下行时间单元激活信息确定激活的时间单元，并将需要传输的下行数据填充至时间(位置)靠前的激活的时间单元处。为方便描述，下文示例中以下行时间单元填充信息为比特位图的方式进行配置为例进行描述。
需要说明的是，主节点填充的数据可以是从主机顺序接收到的数据，该方式适用于下文的示例，重复之处不再赘述。
步骤12：主机为从节点0配置用于进行广播数据传输的第一配置信息；
示例性地，主机为从节点0配置的第一配置信息包括但不限于：下行时间单元激活信息、下行时间单元解调信息和下行时间单元转发信息；其中，下行时间单元激活信息可以是11XXXXXX(X表示不限定，可以是0也可以是1)，下行时间单元解调信息可以是11XXXXXX，下行时间单元转发信息可以是11XXXXXX。对应的，从节点根据各第一配置信息确定，对slot1和slot2执行接收操作、解调操作和转发操作。可以理解地是，slot1和slot2为主节点填充的数据。
步骤13：主机为从节点1配置用于进行广播数据传输的第一配置信息；
主机为从节点1配置的第一配置信息，与主机为从节点0配置的第一配置信息可以相同，请参见步骤12的详细描述，此处不再赘述。
步骤14：主机为从节点2配置用于进行广播数据传输的第一配置信息；
主机为从节点2配置的第一配置信息包括但不限于：下行时间单元激活信息、下行时间单元解调信息和下行时间单元转发信息；其中，下行时间单元激活信息可以是11XXXXXX(X表示不限定，可以是0也可以是1)，下行时间单元解调信息可以是11XXXXXX，下行时间单元转发信息可以是00XXXXXX。由于从节点2为尾端从属节点，没有下级节点，因此从节点2不需要对slot1和slot2进行转发操作，只需要进行接收操作和解调操作。
主机将为各传输节点配置的第一配置信息发送给各传输节点，各传输节点根据配置信息集合中的各第一配置信息确定对于slot1至slot8所需要执行的操作。若主机或master有广播数据待传输，则可以通过slot1和slot2承载该广播数据，广播数据的传输过程为：主机通过slot1和slot2发送广播数据给主节点，主节点确定对slot1和slot2进行接收操作、解调操作和转发操作，即主节点将接收到的slot1和slot2的数据转发至下级节点—从节点0，从节点0将接收到的slot1和slot2的数据转发至下级节点—从节点1，从节点1将接收到的slot1和slot2的数据转发至下级节点—从节点2，各节点分别将接收到的slot1和slot2的数据进行解调，因此，该传输系统中的每个传输节点都可以接收到该数据，以此实现数据广播的功能。
需要说明的是，(1)上述示例的描述步骤仅为举例，步骤11至步骤14没有严格的时间顺序。(2)上述以及下文的示例中主机为各传输节点配置的第一配置信息仅为用于表示能够完成该示例对应的数据传输方式的举例，并非是对主机为各传输节点配置的配置信息的限制，例如，示例1中主机还可以为从节点配置下行时间单元填充信息，或下文中的第二配置信息，本申请实施例对此不作限定。示例性地，主机可以为传输节点配置全部配置信息，该配置信息可以指示不执行该配置信息对应的操作；也可以为传输节点配置部分配置信息，对于未配置的配置信息，预设各传输节点不执行该配置信息对应的操作，例如，若比特位的比特的值为0表示不执行该配置信息对应的操作，以步骤12为例，主机可以为从节点0配置下行时间单元填充信息，该下行时间单元填充信息(比特位图)可以是00XXXXXX，或者，主机不为从节点0配置下行时间单元填充信息，则对于主机未配置的配置信息，传输节点默认该配置信息对应的各比特位的比特值为0(例如00000000)，即不执行该配置信息对应的操作。或者对于未配置的配置信息，各传输节点默认该配置信息为预设值，该预设值可以是初始值，例如，配置信息的初始值为0。
示例2：通过第一配置信息进行数据组播；
以图4所示的系统结构为例，假设从节点1和从节点2为一组，则对于该节点组的组播数据的传输的配置可以是：
步骤21：主机为主节点配置用于进行组播数据传输的第一配置信息；
示例性地，主机为主节点配置的第一配置信息包括但不限于：下行时间单元激活信息和下行时间单元填充信息；其中，下行时间单元激活信息可以是11XXXXXX(X表示不限定，可以是0也可以是1)，下行时间单元填充信息可以是11XXXXXX。对应的，主节点根据各第一配置信息确定，slot1和slot2为激活的时隙，并将需要传输的组播数据填充至slot1和slot2中。应理解地是，对于主节点而言，并不知道需要填充的数据是广播数据还是组播数据，如前所述，主节点可以按照第一配置信息，将从主机顺序接收到的数据，顺序填充至确定的可进行填充的时间单元内。
步骤22：主机为从节点0配置用于进行组播数据传输的第一配置信息；
示例性地，主机为从节点0配置的第一配置信息包括但不限于：下行时间单元激活信息和下行时间单元转发信息；其中，下行时间单元激活信息可以是11XXXXXX(X表示不限定，可以是0也可以是1)，下行时间单元转发信息可以是11XXXXXX。对应的，主节点根据各第一配置信息确定，对slot1和slot2执行接收操作和转发操作。
步骤23：主机为从节点1配置用于进行组播数据传输的第一配置信息；
主机为从节点1配置的第一配置信息包括但不限于：下行时间单元激活信息、下行时间单元解调信息和下行时间单元转发信息；其中，下行时间单元激活信息可以是11XXXXXX(X表示不限定，可以是0也可以是1)，下行时间单元解调信息可以是11XXXXXX，下行时间单元转发信息可以是11XXXXXX。对应的，从节点1根据各第一配置信息确定，对slot1和slot2执行接收操作、解调操作和转发操作。
步骤24：主机为从节点2配置用于进行组播数据传输的第一配置信息；
主机为从节点2配置的第一配置信息包括但不限于：下行时间单元激活信息、下行时间单元解调信息和下行时间单元转发信息；其中，下行时间单元激活信息可以是11XXXXXX(X表示不限定，可以是0也可以是1)，下行时间单元解调信息可以是11XXXXXX，下行时间单元转发信息可以是00XXXXXX。对应的，从节点2根据各第一配置信息确定，对slot1和slot2执行接收操作、解调操作。
上述方式，可以实现从节点1和从节点2的组播数据的传输。
示例3：通过第一配置信息进行数据单播；
以图4所示的系统架构为例，假设主机向从节点0发送单播数据，该单播数据的传输的配置可以是：
步骤31：主机为主节点配置主节点向从节点0发送单播数据的第一配置信息；
主机为主节点配置的第一配置信息包括但不限于：下行时间单元激活信息和下行时间单元填充信息；其中，下行时间单元激活信息可以是11XXXXXX(X表示不限定，可以是0也可以是1)，下行时间单元填充信息可以是11XXXXXX。对应的，主节点根据各第一配置信息确定，slot1和slot2为激活的时隙，并将需要传输的广播数据填充至slot1和slot2中。
步骤32：主机为从节点0配置主机向从节点0发送单播数据的第一配置信息；
主机为从节点0配置的第一配置信息包括但不限于：下行时间单元激活信息和下行时 间单元解调信息；其中，下行时间单元激活信息可以是11XXXXXX，下行时间单元解调信息可以是11XXXXXX。对应的，从节点0根据各第一配置信息确定，对slot1和slot2执行接收操作和解调操作。
上述方式，可以实现主节点和从节点0的单播数据的传输。
示例4：通过第一配置信息指示两传输节点之间进行数据传输；
为方便描述，假设两传输节点为图4中的从节点0和从节点2，从节点0向从节点2发送下行数据，从节点2接收从节点0发送的下行数据。
下面提供本申请实施例的数据传输方法对应的流程，该流程包括如下步骤：
步骤41：主机根据传输节点的数据传输需求，确定各传输节点的第一配置信息。
在一种应用场景中，从节点0连接有麦克风，该麦克风周期性采集音频数据，从节点2连接有扬声器，从节点0采集的音频数据需要通过从节点2进行播放。即从节点0与从节点2具有数据传输需求。则主机可以为从节点0和从节点2配置进行数据传输的时间单元和对应的操作，以完成从节点0和从节点2之间数据传输。
上述从节点0周期性采集的音频数据为规律性数据。假设下行规律时隙包含slot1～slot8，从节点0采集的音频数据需要占用两个时隙，空闲的下行规律时隙为slot3和slot4。
示例性地。为了完成从节点0与从节点2之间的数据传输，主机为从节点0配置的配置信息集合包括但不限于：下行时隙激活信息，可以为00110000，下行时隙填充信息，可以为00110000。主机为slave1配置的配置信息集合包括但不限于：下行时隙激活信息，可以为00110000，下行时隙转发信息，可以为00110000。主机为从节点2配置的配置信息集合包括但不限于：下行时隙激活信息，可以为00110000，下行时隙解调信息，可以为00110000。
步骤42，主机为各传输节点配置配置信息集合，对应的，传输节点根据配置信息集合中的第一配置信息确定预设时间周期中的时间单元对应的操作。
步骤43，主机发送导频和帧头至主节点，主节点将导频和帧头发送至从节点0，从节点0将导频和帧头发送至从节点1，从节点1将导频和帧头发送至从节点2。
步骤44，从节点0将采集到的音频数据填充至slot3和slot4，并将slot3承载的数据和slot4承载的数据发送至从节点1。
步骤45，从节点1接收并将slot3和slot4承载的数据转发至从节点2。
步骤46，从节点2接收并解调slot3和slot4承载的数据。
通过上述方式，可以实现两两节点之间进行数据传输，节点不需要将数据转发至主机后，再由主机进行转发，因此缩短了传输时延，同时节省了数据中转的资源开销。
上文介绍了可用于承载规律数据的时间单元以及该时间单元的配置方式，本申请实施例还提供了另一种预设时间周期的结构，可以提供对于突发的随机数据的传输和反馈。
如图7所示，为本申请实施例提供的预设时间周期中另一种下行时域资源的结构示意图，对应的，该预设时间周期中的上行时域资源的结构与图7所示的上行时域资源的结构可以相同，如图8所示，为上行时域资源的结构示意图。
示例性地，图7和图8为同一预设时间周期，下面以下行时域资源为例，对下行时域资源中的结构中进行介绍。图8与图7类似，只是方向不同，不再赘述。以下仅对图7中与图5所示的结构的不同之处进行说明。
(1)随机时间单元
以图7中时间单元为时隙为例，下行随机时隙用于承载突发的下行随机数据，该下行随机数据的节点的节点编号和该下行随机数据的相关信息，例如该下行随机时隙的业务类型或优选级信息。
这里的随机数据，是指数据传输需求不固定，多为突发性，不可预估的数据或者是低频数据。示例性地，不可预估的数据包括传感器检测到的数据，例如温度传感器、湿度传感器或震动传感器所检测到的异常数据。再示例性地，低频数据为采样频率为小于预设频率的数据，例如采样频率小于1Hz的数据。
具体的，下行随机数据的接收端可以是一个或多个预设的传输节点，该传输节点可以具备数据处理的能力，示例性地，该传输节点可以执行主机的数据处理功能。同样的，上行随机数据的接收端也可以是一个或多个预设节点，例如主机。
(2)反馈时间单元
以图7中时间单元为时隙为例，下行反馈时隙用于承载反馈信息，该反馈信息用于指示对应的随机时隙承载的随机数据成功接收或未成功接收。
具体的，下行随机时隙1～y与该下行随机时隙所在的预设时间周期中的上行反馈时隙1～y一一对应。举例来说，图7中的下行随机时隙1～y与图8中的上行反馈时隙1～y一一对应。换而言之，预设时间周期中的上行反馈时隙1～y分别用于承载同一预设时间周期中的下行随机时隙1～y中承载的下行随机数据对应的上行反馈信息，该上行反馈信息用于指示至少一个第四时间单元中承载的上行随机数据成功接收或未成功接收。
举例来说，上行反馈时隙1用于承载对下行随机时隙1的反馈信息，示例性地，该反馈信息包括下行随机时隙1中承载的节点编号和承载的随机数据的业务类型或优选级信息。
图8中的上行随机时隙1～m与下一预设时间周期中的下行反馈时隙1～m一一对应。换而言之，相邻两个预设时间周期中后一个预设时间周期中的下行反馈时隙1～m分别用于承载前一个预设时间周期中的上行随机时隙1～m中承载的上行随机数据的下行反馈信息，用于指示上行随机时隙1～m中承载的上行随机数据成功接收或未成功接收。
第一种可选的实施方式，该反馈信息包括但不限于该slave2在下行随机时隙i接收到的下行随机时隙i中包含的节点编号和随机数据1的业务类型。
示例性地，业务类型可以是传感器采集的信号的类型，例如温度信号、震动信号、压力信号灯，本申请实施例对此不作限定。
第二种可选的实施方式，该反馈信息包括但不限于该slave2在下行随机时隙i接收到的下行随机时隙i中包含的节点编号和随机数据1的优先级信息。
优先级用于表征该业务类型的信号的重要程度，其中，不同业务类型对应的优先级可以完全不同，也可以不完全相同，换而言之，业务类型可以与优先级一一对应，或者是多个业务类型也可以对应于同一个优先级。例如，业务类型包含温度、震动、压力，则温度信号的优先级可以是1，震动信号的优先级是2，压力信号的优先级是3。或者温度信号和压力信号的优先级均为1，震动信号的优先级为2。
需要说明的是上行反馈时隙与对应的下行随机时隙承载的信息的类型应相同，例如，下行随机时隙承载的为随机数据的业务类型信息，则对应的上行反馈时隙中也应包含该随机数据的业务类型信息，若下行随机时隙承载的为随机数据的优先级信息，则上行反馈时隙中也应包含该随机数据的优先级信息。
第三种可选的实施方式，除上述信息之外，该反馈信息还可以包括接收结果信息，具体的，接收结果可以是成功接收或未成功接收，其中，成功接收是指接收到并正确解调该数据，未成功接收是指，未接收或未正确解调该数据，示例性地，成功接收为ACK(acknowledge character，肯定应答)，未成功接收为NACK。
对应的，在上述第一种和第二种可选的实施方式中，假设下行随机时隙i中的节点编号为slave0，也就是，该下行随机时隙i中的随机数据为slave0发送的，对应的，slave0会接收对应的上行反馈时隙i的反馈信息，若该反馈信息包含自身的节点编号和业务类型或优先级信息，则确定slave2的接收结果为成功接收，即不需要重传该随机数据，否则，确定slave2未成功接收，slave0需要向slave2重传该随机数据。示例性地，slave0在下一预设时间周期的下行随机时隙向slave2重传该随机数据。
在上述第三种可选的实施方式中，若slave0在上行反馈时隙i的反馈信息包含自身的节点编号和业务类型或优先级信息和ACK，则确定不需要重传，否则，确定需要重传该随机数据。
(3)帧头
下行帧头包含帧号、第二指示信息和其他信息，该第二指示信息用于指示剩余的下行随机时隙的数量；上行帧头包含帧头、第三指示信息和其他信息，该第三指示信息用于指示剩余的上行随机时隙的数量。
示例性地，具有随机数据传输需求的传输节点可以根据自身的随机数据的大小和随机时隙可以承载的数据的大小确定该随机数据所需的随机时隙的数量，在接收到的帧头时，根据帧头中指示的剩余的随机时隙的数量以及自身的随机数据所需的随机时隙的数量，修改帧头中的剩余随机时隙的数量，并将随机数据传输至剩余的时隙中。
例如，下行随机时隙包括下行随机时隙1至下行随机时隙3，从节点1接收来自从节点0的下行帧头，该下行帧头中的第二指示信息指示剩余的下行随机时隙为2，即还剩余2个下行随机时隙。从节点1有下行随机数据，该下行随机数据需要占用1个下行随机时隙，则从节点1将该第二指示信息指示的剩余的下行随机时隙的数量修改为1，若从节点1的下行随机时隙需要占用2个下行随机时隙，则从节点1将第二指示信息指示的剩余的下行随机时隙的数量修改为0，并将该第二指示信息发送至下级节点—从节点2。
需要说明的是，(1)本申请实施例提供的上行时域资源或下行时域资源中，各类型的时间单元可以是一个或多个，例如，预设时间周期中的规律时隙、反馈时隙或随机时隙均可以为一个或多个。(2)第二指示信息还可以是通过其他信息承载的，本申请实施例对此不作限定。(3)下行时域资源和上行时域资源中相同类型的时间单元的数量可以是相同的，也可以是不同的，本申请实施例对此不作限定。例如，其中，对于下行规律时隙1～n与上行规律时隙1～k，n与k可以相同也可以不同，下行随机时隙1～y与上行随机时隙1～m，y与m可以相同也可以不同，本申请实施例对此不作限定。举例来说，同一个预设时间周期内，下行时域资源可以包含8个规律时隙，2个反馈时隙，2个随机时隙，上行时域资源可以包含4个规律时隙，4个反馈时隙，4个随机时隙。(4)规律时间单元、反馈时间单元、随机时间单元所承载的数据的长度可以是相同的，也可以是不同的，例如，每个规律时隙可以承载32bit的数据，每个随机时隙承载的数据可以为32bit，也可以不是32bit，优选地，如图7或图8可知，由于随机时隙中还需要承载节点编号和业务类型或优先级等信息，因此，每个随机时隙中承载的数据可以大于32bit。
本申请实施例可以通过第二配置信息来配置随机时隙，接下来对第二配置信息进行详细介绍。
本申请实施例中配置信息集合中还可以包含第二配置信息，第二配置信息可以用于配置上行随机时隙的信息，和/或下行随机时隙的信息。该信息可以包括但不限于随机时隙的位置信息和/或数量信息。为了方便描述，下文将用于配置下行随机时隙的第二配置信息称为下行随机时间单元信息，将用于配置上行随机时隙的第二配置信息称为上行随机时间单元信息。
接下来对上述第二配置信息进行具体介绍：
(1)下行随机时间单元信息，用于指示下行随机时间单元的信息。
示例性地，主机可以为具有随机数据业务的传输节点配置第二配置信息，从而为该传输节点指示可以用于承载随机数据的下行随机时间单元的位置和/或数量。对应的，传输节点可以使用下行随机时间单元中空闲的时间单元承载自身的下行随机数据，并发送至下级节点。
示例性地，下行随机时间单元信息来指示下行随机时间单元的位置和数量时，下行随机时间单元信息可以为比特位图，每个比特位分别用于指示一个下行随机时间单元，例如，假设下行时域资源包括slot1～slot8，下行随机时间单元信息可以是00000011。其中，1表示该比特位对应的时间单元为随机时间单元，0表示该比特位对应的时间单元不是随机时间单元，则00000011表示，slot7和slot8为下行随机时间单元。对应的，配置有该下行随机时间单元信息的传输节点，可以将自身的下行随机数据填充至slot7和/或slot8中。优选的，传输节点首先将随机数据填充在位置(时间)靠前的随机时间单元中。
又示例性地，下行随机时间单元信息来指示下行随机时间单元的数量时，第二配置信息还可以为一指示值，该指示值可以用于指示随机时间单元的数量。例如，下行随机传输时间单元信息为00000010，该字符串的取值为2，则表示预设时间周期内的下行随机时间单元的数量为2。又例如，下行随机传输时间单元信息为00000011，该字符串的取值为3，则表示预设时间周期内的下行随机时间单元的数量为3。其中，随机时间单元的位置可以是预设的，例如，下行随机时间单元位于下行时域资源的末尾位置，上行随机时间单元位于上行时域资源的末尾位置。例如，下行时域资源包括slot1至slot16，若下行随机时间单元的数量为2，则下行随机时间单元为slot15和slot16；若下行随机时间单元的数量为3，则下行随机时间单元为slot14至slot16，即随机时间单元总是位于时域资源的末尾位置。
(2)上行随机时间单元信息，用于指示上行随机时间单元的信息，具体可以参见上述下行随机传输时间单元信息，此处不再赘述。
需要说明的是，各传输节点对于随机时间单元的预设操作包括接收操作和转发操作；对于配置有第二配置信息的节点，在具有随机数据时还可以在随机时隙上进行填充操作；对于随机数据的接收节点，对于随机时隙的预设操作包含接收操作和解调操作。
各传输节点对于反馈时间单元的预设操作包含接收操作和转发操作，其中，若传输节点通过随机时间单元发送了随机数据，则该传输节点在该随机时间单元对应的反馈时间单元上，还需要进行接收操作和解调操作。示例性地，上述预设操作可以通过第一配置信息进行配置，也可以是协议约定或预定义的。例如，通过上行时间单元填充信息来指示可以进行填充的上行随机时隙，通过上行时间单元激活信息、上行时间单元解调信息和上行时 间单元转发信息来指示各传输节点对上行随机时隙的激活、解调或转发操作，具体请参见上文对第一配置信息的描述，此处不再赘述。
下面结合具体的实施例对上述技术方案进行详细介绍。
请参考图9，为本申请实施例提供的另一种通信方法所对应的流程示意图，如图9所示，该流程包括：
步骤S901：主机确定第二配置信息；
具体的，第二配置信息属于配置信息集合，示例性地，配置信息集合可以包含一个或多个配置信息。可选的，该配置信息集合还可以包含第一配置信息。
示例性地，主机可以根据传输节点的业务传输需求，示例性地，该传输节点的业务数据为突发的随机数据，例如，该传输节点的外围设备为传感器，或该传输节点，或该传输节点的外围设备的采样频率较低时，主机为该传输节点配置第二配置信息。
步骤S902：主机将第二配置信发送给该传输节点。
步骤S903，传输节点接收该第二配置信息；
具体的，对于步骤S902、步骤S903的实现方式可以参见上述步骤S602、步骤S603的具体描述，此处不再赘述。
步骤S904，传输节点根据第二配置信息确定随机时间单元的信息。
步骤S905，传输节点通过确定的随机时间单元发送随机数据。
具体的，传输节点通过确定的下行随机时间单元发送下行随机数据，或，传输节点通过确定的上行随机时间单元发送上行随机数据。
步骤S906，传输节点接收确定的随机时间单元对应的反馈时间单元承载的反馈信息。
若反馈信息指示该确定的随机时间单元的随机数据未成功接收，则该传输节点重传该随机数据。例如，传输节点通过确定的下行随机时间单元发送下行随机数据，并接收同一预设时间周期中该下行随机时间单元对应的上行反馈时间单元承载的反馈信息，若该反馈信息指示该下行随机时间单元的下行随机数据未成功接收，则该传输节点可以通过下一预设时间周期的下行随机时间单元重传该下行随机数据。又例如，传输节点通过确定的上行随机时间单元发送上行随机数据，并接收下行预设时间周期中该上行随机时间单元对应的下行反馈时间单元承载的反馈信息，若该反馈信息指示该上行随机时间单元的上行随机数据未成功接收，则该传输节点可以通过下一预设时间周期的上行随机时间单元重传该上行随机数据。
应理解地是，主机可以通过第一配置信息协调各传输节点的数据收发操作，以避免传输节点之间对于规律时间单元可能产生的数据冲突。而随机时间单元为1个或多个传输节点共享的时间单元，各传输节点的随机数据是不可预期的，当存在多个传输节点均存在随机数据传输需求时，传输节点之间可能在同一随机时间单元发生冲突，例如，以下行随机时间单元为例，假设下行随机时间单元的标识为slot7和slot8，结合图4，从节点0和从节点1均具有下行随机数据，由于从节点0为从节点1的上级节点，从节点0先于从节点1将从节点0自身的下行随机数据填充至slot7和slot8中，从节点1也希望将自身的下行随机数据填充至slot7和/或slot8中，此时，发生冲突。
可选的，第二配置信息中的部分字段还可以用于指示是否使能该传输节点的覆盖功能。例如，用1个比特来指示该功能时，该1个比特位于第二配置信息中的左起第一个比特位， 示例性地，若第二配置信息的第一个比特位上的比特的值为1时，表示该传输节点的覆盖功能使能，若第二配置信息的第一个比特位上的比特的值为0时，表示该传输节点的覆盖功能去使能，可选的，该第二配置信息对应的字符串的剩余比特位的取值可以用于表示随机时间单元的数量。例如，上行随机时间单元信息为10000010，第一个比特位为1，表示可以上行覆盖功能使能，后7个比特位的取值为2，表示上行随机时间单元的数量为2。下行随机时间单元信息为00000011，第一个比特位为0，表示下行覆盖功能去使能，后7个比特位的取值为3，表示下行随机时间单元的数量为3。
需要说明的是，上述仅为举例，用于指示是否激活覆盖功能的信息还可以是其他信息，例如，一个单独的配置信息，本申请实施例对此不作限定。
下面分别对覆盖功能使能和覆盖功能去使能进行说明：
(1)激活覆盖功能(覆盖功能使能)，是指该传输节点的随机数据与其他传输节点的随机数据冲突时，即传输节点需要通过随机时间单元发送随机数据，而该随机时间单元已承载有其他传输节点的随机数据，该传输节点可覆盖其他传输节点的随机数据，具体的，该传输节点还需要进一步判断是否可以覆盖其他传输节点的随机数据，例如根据两个随机数据的优先级进行判断。举例来说，假设下行随机传输时间单元信息指示传输节点A为覆盖功能使能，在该传输节点的随机数据与其他传输节点的随机数据冲突时，即下行随机时间单元已承载随机数据时，该传输节点A可以获取该下行随机时间单元所承载的随机数据的优先级(称为第一优先级)信息，可以理解地是，该随机数据为该传输节点A与主机之间的任一中间节点的随机数据，该传输节点A根据自身的随机数据的优先级(称为第二优先级)，和该中间节点(包括上级节点)的随机数据的优先级进行比较，若第二优先级高于第一优先级，则该传输节点A可以将自身的随机数据覆盖该承载该中间节点的随机数据，否则，不能覆盖，该传输节点A需要将该随机数据转发至下级节点。
(2)去激活覆盖功能(覆盖功能去使能)，是指该传输节点的随机数据与其他传输节点的随机数据冲突时，该传输节点不支持覆盖其他传输节点的随机数据。也就是，若该传输节点的覆盖功能去使能，则该传输节点只能使用空闲的随机时间单元承载自身的随机数据。
为了便于描述，下文中，以第二指示信息用于指示剩余的下行随机时隙的第一数量，第三指示信息用于指示剩余的上行随机时隙的第二数量，该传输节点的上行随机数据所需的上行随机时隙的数量为第三数量，该传输节点的下行随机数据所需的下行随机时隙的数量为第四数量为例，对传输节点通过确定的随机时间单元发送随机数据的流程进行描述。该流程可以包含如下几种情况：
情况1：若第一数量大于第四数量，则传输节点之间随机数据未发生冲突；
情况2：若第一数量小于第四数量，且第一数量大于0，则传输节点的部分下行随机数据发生冲突；
情况3：若第一数量为0，则传输节点的全部下行随机数据发生冲突。
下面通过具体的示例对上述几种可能的情况进行举例说明。
示例一：传输节点之间随机数据未发生冲突；
该示例一结合图7和图8所示的预设时间周期的结构，以下行随机时隙为例，对发送下行随机数据和接收上行反馈信息的流程进行介绍。该流程可以包括如下步骤：
步骤A1，传输节点根据第二配置信息确定下行随机时隙。
示例性地，预设下行随机时隙位于下行时域资源的末尾部分，预设上行随机时隙位于上行时域资源的末尾部分，第二配置信息用于指示下行随机时隙的数量，传输节点根据第二配置信息确定下行随时时隙的数量和预设随时时隙的位置确定预设时间周期中的一个或多个下行随时时隙，例如，确定一个或多个下行随机时隙的起始位置。
步骤A2，传输节点确定自身的下行随机数据所需占用的下行随机时隙的数量。
该传输节点的下行随机数据的大小和每个下行随机时隙所能够承载的数据的大小，确定自身的随机数据所需的随机时间单元的数量。例如，1个下行随机时隙能够承载32bit的数据，假设该传输节点的下行随机数据为60bit，则需要2个下行随机时隙来承载该下行随机数据。
一种可能的场景中，传输节点在接收下行帧头时，没有下行随机数据传输需求，而当将下行帧头发送至下级节点之后，产生了下行随机数据，则该传输节点可以在下一个预设时间周期内传输该下行随机数据。
步骤A3，传输节点根据下行帧头中的第二指示信息确定剩余的下行随机时隙的数量；
具体的，传输节点可以判断第一数量是否大于第四数量。示例性地，第一数量不小于第四数量，执行步骤A4；
步骤A4，该传输节点将自身的下行随机数据填充至剩余的下行随机时隙中。
具体的，若下行随机时隙的数量为多个，或剩余的下行随机时隙的数量为多个，则可以预设传输节点填充下行随机时隙的方式，例如，为了保持下行信息的连续性(没有空闲时隙间隔)，各传输节点可以首先填充位置(时间)靠前的随机时隙，例如，下行随机时隙按照时间顺序排列的标识为slot7，slot8，slot9，则传输节点首先使用slot7传输下行随机数据，然后再填充slot8，以此类推。
因此，传输节点可以根据第二配置信息确定的一个或多个下行随机时隙的位置和预设填充规则确定剩余的(空闲的)下行随机时隙的位置。
例如，图7中的下行随机时隙的起始时隙为slot7，下行随机时隙的数量为3，随机时隙的预设填充规则为先填充时间靠前的随机时隙，若剩余随机时隙的数量为1，则剩余的该随机时隙为slot9。若剩余随机时隙的数量为2，则剩余的该随机时隙为slot8和slot9。
需要说明的是，若传输节点在使用了下行随机时隙，且剩余下行随机时隙的数量发生变化时，该传输节点需要更新下行帧头中的第二指示信息，用于向下级节点指示剩余的最新的下行随机时隙的数量。
步骤A5，下行随机时隙的预设接收节点接收下行随机时隙承载的数据，并通过下行随机时隙对应的上行反馈时隙发送该下行随机时隙承载的数据的反馈信息。
步骤A6，该传输节点接收使用的下行随机时隙对应的上行反馈时隙承载的反馈信息。
示例二，传输节点的部分下行随机数据发生冲突；
在示例二中，仅对与示例一不同之处进行说明。
在步骤A3中，第一数量小于第四数量，且第一数量大于0；
步骤B1，传输节点判断是否可以覆盖冲突的下行随机时隙中已承载的随机数据；
若第二指示信息指示第一数量大于0，且小于第四数量，即存在空闲的随机时隙，但不能完全承载该传输节点的下行随机数据。
可以理解的是，冲突的下行随机时隙是指该传输节点的下行随机数据所需的下行随机 时隙的第四数量与剩余的下行随机时隙的第一数量的差值，例如，第四数量为2，第一数量为1，则冲突的下行随机时隙为1个，根据预设填充规则，首先填充位置靠前的下行随机时隙，因此，该1个下行随机时隙的为首个下行随机时隙。其中，冲突的下行随机时隙所承载的下行随机数据为该传输节点的上级节点，例如，该传输节点为图4中的从节点2，则冲突的下行随机时隙承载的随机数据可以是主节点的，也可以是从节点0的，也可以是从节点1的。
该传输节点可以通过覆盖冲突的下行随机时隙的数据的方式，来传输自已的下行随机数据，也可以选择不覆盖。若通过覆盖方式来传输，其过程包括：
(1)根据第二配置信息确定是否可以激活覆盖功能；
若覆盖功能使能，则进入流程(2)。
(2)获取发生冲突的下行随机时隙承载的随机数据的优先级信息，将冲突的随机数据的优先级与该传输节点自身的下行随机数据的优先级进行比较。
若该传输节点自身的下行随机数据的优先级较高，则该传输节点可以将自身的部分下行随机数据覆盖至发生冲突的，且承载的随机数据的优先级较低的下行随机时隙处；
若该传输节点自身的下行随机数据的优先级较低，则该传输节点不能覆盖该冲突的随机数据，该传输节点需要接收并转发发生冲突的下行随机时隙承载的随机数据。
例如，下行随机时隙1～下行随机时隙3承载有随机数据，剩余的下行随机时隙的数量为M个，假设该传输节点自身的下行随机数据所需的下行随机时隙的数量为M+1个，也即该传输节点可以将自身的下行随机数据填充至剩余的M个下行随机时隙之后，还需要占用1个下行随机时隙，假设预设覆盖规则为先覆盖时间靠前的下行随机时隙，则该传输节点还需要覆盖下行随机时隙1，具体的，该传输节点获取下行随机时隙1承载的随机数据的优先级(称为第一优先级)的信息，将第一优先级与该传输节点自身的下行数据的优先级(称为第二优先级)进行比较，若第二优先级高于第一优先级，则将该传输节点自身的部分下行随机数据覆盖该下行随机时间单元1，否则，不覆盖下行随机时隙1，该传输节点接收并转发下行随机时隙1承载的下行随机数据。
可选的，该传输节点通过上述方式继续比较下行随机时间单元2是否可以覆盖，若依然不可以覆盖，则再比较下行随机时间单元3，依此类推，直至接收到空闲的下行随机时隙，若传输节点将部分数据填充至下行随机时间单元1～下行随机时间单元3的任一个时间单元中，则该传输节点将剩余的下行随机数据填充至剩余的M个下行随机时隙中，即从下行随机时隙4开始直至下行数据帧结束。
示例性地，该传输节点将自身的下行随机数据的部分，例如前部分，填充至确定的可以覆盖的下行随机时隙处，将该下行随机数据中剩余的部分(后部分)填充至空闲的下行随机时隙处。例如，该传输节点的下行随机数据包含两部分，数据1和数据2，数据1为需要覆盖的下行随机时隙所能承载的数据部分，当需要覆盖的下行随机时隙到达时，该传输节点将数据1填充至该下行随机时隙，当空闲的下行随机时隙到达时，该传输节点将数据2依次填充至到达的下行随机时隙中。
步骤B2，下行随机时隙的预设接收节点接收下行随机时隙承载的数据，并通过下行随机时隙对应的上行反馈时隙发送该下行随机时隙承载的数据的反馈信息。
步骤B3，该传输节点接收使用的下行随机时隙对应的上行反馈时隙承载的反馈信息。
例如，预设时间周期中，下行随机时隙为下行随机时隙1～下行随机时隙M-3，对应的，上行反馈时隙为上行反馈时隙1～上行反馈时隙M-3。该传输节点使用了下行随机时隙1和下行随机时隙4～下行随机时隙M-3；则该传输节点需要接收同一预设时间周期中的上行反馈时隙1、上行反馈时隙4～上行反馈时隙M-3。
若其中的一个或多个上行反馈时隙指示的接收结果为未成功接收，则该传输节点需要重新传输对应的下行随机时隙承载的随机数据，例如，上行反馈时隙1指示下行随机时隙1承载的随机数据(数据1)未成功接收，则该传输节点可以在下个预设时间周期中重复发送该数据1。对于成功接收的随机数据则不需要重传。
举例来说，结合图4所示的系统架构，假设下行随机时隙的预设接收节点为slave2，slave2根据对各下行随机时隙承载的随机数据的接收结果，将各下行随机时隙对应的反馈信息填充至同一预设时间周期中对应的上行反馈时隙中。
第一种可实施的方式，下行随机时隙承载的信息包括下行随机数据(图7中的业务数据)、发送该下行随机数据的节点的节点编号，该下行随机数据的业务类型。对应的，该下行随机时隙对应的上行反馈时隙承载的反馈信息可以包括：接收节点接收到的下行随机时隙中承载的节点编号(应注意可能有多个传输节点对该时隙进行了覆盖，接收节点接收到的为最终承载的节点编号)，以及该下行随机时隙中承载的随机数据的业务类型。
对应的，若该传输节点接收到的反馈信息包含自身的节点编号和业务类型，则对应的下行随机时隙中承载的随机数据成功接收，否则，对应的下行随机时隙中承载的随机数据位成功接收。
需要说明的是，若下行随机时隙承载的为业务类型，则传输节点可以根据业务类型与优先级的预设对应关系确定该下行随机时隙承载的随机数据的优先级。
第二种可实施的方式，还可以不发送随机数据的业务类型，使用优选级信息替代业务类型，即下行随机时隙和上行反馈时隙中承载的均为优先级信息。
对应的，若该传输节点接收到的反馈信息包含自身的节点编号和优选级信息，则对应的下行随机时隙中承载的随机数据成功接收，否则，对应的下行随机时隙中承载的随机数据位成功接收。
可选的，反馈信息还可以包含ACK(acknowledgement，肯定应答)/NACK(negative acknowledgement，否定应答)，用于指示接收结果是成功接收还是未成功接收。
示例性地，对于需要重传的随机数据，其重发粒度可以是一个下行随机时间单元所承载的部分随机数据，例如，若传输节点根据反馈信息确定仅其中一个下行随机时隙的数据未成功接收，则可以仅重传该下行随机时隙承载的随机数据，对于成功接收的随机时间单元的部分随机数据，是不需要重传的。
可以理解地是，未成功接收的情况，可能是该下行随机时隙的随机数据被该传输节点的下级节点覆盖，也可以是其他原因，例如，未正确解码等。
因此，对于下行随机数据被覆盖的传输节点，也需要接收对应的上行反馈时隙。例如，该传输节点的数据1覆盖了下行随机时隙1中已承载的随机数据，该已承载的随机数据为从节点0的，该从节点0也需要接收该下行随机时隙1对应的上行反馈时隙1的反馈信息。
由于随机数据为不可预期，因此对于发送了下行随机数据的传输节点以及该传输节点的下级节点对于各随机时隙的预设操作包括接收操作和转发操作，作为进一步优化，可以根据下行帧头的第二指示信息确定已承载随机数据的下行随机时隙，执行接收操作和转发 操作；对于未承载随机数据的下行随机时隙，则可以提前结束接收操作和转发操作，以节省能耗。可选的，传输节点还可以通过能量检测的方式来判断空闲的下行随机时隙，该能量检测的方式为基于现有技术的实现，此处不进行详细描述。
示例三，传输节点的全部下行随机数据发生冲突；
在示例二中，仅对与示例一不同之处进行说明。
在步骤A3中，第一数量为0，该示例中，该传输节点通过上述示例2中的方式判断是否可以覆盖其他节点的随机数据，若可以覆盖，再依次将每一个冲突的下行随机时隙中承载的随机数据的优先级与该传输节点自身的下行随机数据的优先级进行比较，以此确定可以覆盖的下行随机时隙，具体请参见上述示例二中的描述，此处不再赘述。
需要说明的是，上述以下行随机时隙为例进行说明的，对于上行随机时隙的通信方式可以参见上述下行随机时隙的具体描述，此处不再赘述。
本申请实施例主机还可以为传输节点配置第三配置信息，该第三配置信息可以属于配置信息集合。示例性地，第三配置信息用于指示预设时间周期的标识；再示例性地，第三配置信息用于指示相邻两个预设时间周期之间的时间间隔。具体的，该预设时间周期为主机为该传输节点配置的第一配置信息和/或第二配置信息有效的时间周期。
示例性地，主机可以根据传输节点的采样周期(或采样频率)配置第一配置信息和/或第二配置信息的有效的周期，例如，假设时间周期的周期标识为1，2，3…n，达到n后，周期标识重新计数。若该传输节点的采样周期不大于预设时间周期，则有效的周期(即预设时间周期)可以是所有的周期；若采样周期为预设时间周期的2倍，则有效的周期可以是周期标识为偶数的周期，例如，2，4，6…，也可以是周期标识为奇数的周期，例如1，3，5…。
举例来说，如下表2所示，为本申请实施例提供的第三配置信息的一具体示例。
表2
Figure PCTCN2020087919-appb-000003
需要说明的是，上述表2仅为举例，本申请实施例对第三配置信息的字符串长度和不同字符串的值对应的周期标识不作限定。
再示例性地，第三配置信息还可以用于指示相邻两个预设时间周期之间的时间间隔。例如，第三配置信息可以为一指示值，该指示值表示间隔周期的数量。例如，若间隔周期的数量为1，则第三配置信息可以是01，若间隔周期的数量为2，则第三配置信可以是10，若间隔周期的数量为3，则第三配置信息可以是11。
在有效的周期内，即预设时间周期内，传输节点按照主机配置的第一配置信息和/或第二配置信息确定对应的操作。在有效的周期内，传输节点执行主机配置的第一配置信息和/或第二配置信息对应的操作。在无效的周期内，传输节点可以不按照主机配置的第一配置信息和/或第二配置信息执行操作。
一种可选的实施方式，该传输节点在无效的周期内可以是休眠状态，处于休眠状态的 传输节点可以仅监听时间周期中的导频和帧头部分，不执行第一配置信息和第二配置信息对应的操作，即不进行规律数据、随机数据或反馈信息的传输；
另一种可选的实施方式，该传输节点在无效的周期内可以按照第二配置信息进行随机数据的传输，例如，该传输节点的有效的周期为周期标识是奇数的周期，若该传输节点在周期标识为偶数的周期内有随机数据，则可以在该周期中传输随机数据。
可选的，还可以进行反馈信息的传输。例如，从节0的有效的周期的周期标识为奇数，若从节点0在周期标识为3的周期内接收到上行随机时隙n承载的上行随机数据，则从节点0可以在下一周期即周期标识为4的周期内通过对应的下行反馈时隙n发送反馈信息。
