一种资源调度方法、通信装置与终端设备 技术领域
本申请涉及无线通信技术领域，具体涉及一种资源调度方法、通信装置与终端设备，尤其涉及短距离通信领域。
背景技术
在无线通信中，一个区域内可能存在多个通信域。通信域是由一组具有通信关系的通信节点以及各通信节点之间的通信链路组成的系统。一个通信域可以包括一个主通信节点(可以简称为主节点)和至少一个从通信节点(可以简称为从节点)，其中，主节点管理通信域的时频资源，并且主节点可以为从节点调度时频资源，从节点根据主节点的调度，使用主节点分配的资源进行数据传输。但是，一个通信域中可能存在多种类型的业务数据以及系统控制信息需要进行传输，不同的数据传输或信息的传输可能占用相同或不同的时频资源，因此目前亟需一种灵活的资源调度方式。

具体实施方式
为了方便理解本申请实施例，下面介绍与本申请实施例相关的术语：
(1)通信域，是指一组具有通信关系的通信节点以及通信节点之间的通信连接关系组成的系统。一个通信域包括至少一个主通信节点(可以简称为主节点)和至少一个从通信节点(可以简称为从节点)，其中，主节点管理通信域的时频资源，负责为从节点分配资源，从节点根据主节点的调度，使用主节点分配的资源进行数据传输。
通信节点可以为各种装置或设备，例如在广域无线通信系统的通信域中，主节点可以为基站，从节点可以为终端设备，基站与终端设备之间可以进行数据交互，基站负责管理资源并为终端设备分配资源，终端设备可以使用基站分配的资源与基站进行通信。又例如在局域无线通信系统中，主节点可以为接入点(access point，AP)，从节点可以为站点(station)，接入点可以为站点分配资源，站点可以在接入点分配的资源上与接入点进行通信。再例如，在车载通信系统中，主节点可以为驾驶舱域控制器，从节点可以为车载音箱、车载麦克等装置，驾驶舱域控制器可以为车载音箱子、车载麦克等装置分配资源，车载音箱、车载麦克等装置可以使用驾驶舱域控制器分配的资源与驾驶舱域控制器进行通信。
(2)驾驶舱域控制器(cockpit domain controller或control domain cockpit，CDC)，简称车机，目前车机的功能除了传统的收音机、音乐时频播放、导航功能以外，已经带有蜂窝通信功能(3G，4G等)，能结合汽车的控制器局域网络总线(controller area net-work bus，CAN-BUS)技术，实现人与车，车与外界的信息通讯，增强了用户体验及服务、安全相关的功能。
(3)传输方向，包括上行和下行，其中，上行为从节点向主节点发送消息或信号；下行为主节点向从节点发送消息或信号。对于无需区分或不产生混淆的场景，上行和下行也可统称为上下行。本申请的方案中，上行下行仅仅是为了方便阐述信息的流向。
(4)消息，用于承载一个或多个信息，或用于承载一个或多个信令，例如一个消息中可以包括多个字段，每个字段可以为一个信息或一个信令。
信息，需要接收端节点在接收到信息并进行解码后，才能获取该信息所包含的具体内容。例如，在无线通信系统中信息包括业务信息、系统信息、控制信息等，其中，控制信息又可以称为信令。系统信息用于传递通信域的相关参数或通信域中主节点的参数配置信息或公共配置参数，系统信息为通信域内从节点或请求加入当前通信域的从节点均需要获知的信息，例如资源池的配置信息可以为一种系统信息。又例如新空口(new radio，NR)系统或长期演进(Long Term Evolution，LTE)系统中的SIB、MIB也可以为一种系统信息。可以理解的是，系统信息也可以是一种控制信息。
信令，是指无线通信系统中的控制信息，在无线通信系统的接入层中，信令可以分为物理层信令和高层信令，其中，物理层信令为在物理层传输的控制信息，如公共控制信令，公共控制信令是通信域中主节点在物理层以广播方式发送的，用于向主节点管理的通信域内的从节点发送指示信息的信令。高层信令是指接入层中除物理层以外的其它协议层中传 输的控制信息。
信号，为无线通信系统中接收端节点在收到信号之前，可以预先获知信号对应的序列。接收端节点在接收到与自身相关的信号后，可以进行信号对应的处理。
可以理解的是，本申请实施例中发送信息可以理解为发送承载该信息的消息，例如，第二节点发送系统信息，可以理解为第二节点发送承载系统信息的消息。
(5)终端设备，又称之为用户设备(user equipment，UE)、移动台(mobile station，MS)、移动终端(mobile terminal，MT)等，是一种向用户提供语音和/或数据连通性的设备。例如，终端设备包括具有无线连接功能的手持式设备、车载设备等。目前，终端设备可以是：手机(mobile phone)、平板电脑、笔记本电脑、掌上电脑、移动互联网设备(mobile internet device，MID)、可穿戴设备，虚拟现实(virtual reality，VR)设备、增强现实(augmented reality，AR)设备、工业控制(industrial control)中的无线终端、无人驾驶(self driving)中的无线终端、远程手术(remote medical surgery)中的无线终端、智能电网(smart grid)中的无线终端、运输安全(transportation safety)中的无线终端、智慧城市(smart city)中的无线终端，或智慧家庭(smart home)中的无线终端等。
下面将结合附图对本申请实施例作进一步地描述说明。
以车内通信场景为例，基于当前以及未来的技术演进，车载应用趋于多样化，车内的通信节点数量、类型都越来越多，对于车载通信的能力也就提出了更高的要求。相比现有的有线通信，车载无线通信可以进一步降低车内的线束数量、线束长度、线束重量，以及与之对应的安装、维护、或保养等成本，这使得车载通信有逐步向无线化发展的趋势。
图1为一种车载通信链路的拓扑关系示意图，从图1可以看出，车内存在多个通信域，其中的一个通信域包括一个主节点和至少一个从节点，其中，主节点调度从节点，实现主从节点间互相传输业务数据。例如图1中，手机、耳机和穿戴式设备属于一个通信域，例如称为通信域1，其中手机是主节点，耳机和穿戴式设备是从节点；座舱域控制器(cockpit domain controller，CDC)、显示屏、麦克、音箱属于一个通信域，例如称为通信域2，其中CDC是主节点，显示屏、麦克和音箱是从节点；无钥匙进入及启动(passive entry passive start，PEPS)系统、车身控制模块(body control module，BCM)、手机钥匙和车钥匙属于一个通信域，例如称为通信域3，其中PEPS系统是主节点，BCM、手机钥匙和车钥匙是从节点。另外，一个通信域的主节点也可以作为另一个通信域的从节点，例如，通信域1中的手机可以作为通信域2的从节点。
主从节点间互相传输的信息可包括业务数据、信令，或主从节点之间还可以传输一些信号(如同步信号或参考信号等)。其中，业务数据可包括降噪业务对应的业务数据或动态业务对应的业务数据等类型，信令可包括物理层信令或高层信令等类型。
降噪业务是车载通信需要支持的常见业务，降噪业务可由图1所示的通信域2来执行。降噪业务包含从节点到主节点的数据传输，例如用于降噪的麦克采集环境中的噪声数据，并将噪声数据发送给CDC；以及，降噪业务还包含主节点到从节点的数据传输，例如CDC在接收噪声数据后，可生成与噪声数据的振幅相同、相位相反的数据，并将该数据发送给音箱，以实现降噪。降噪业务的业务量在几mbps到几十mbps，甚至更多，在车载通信的总体业务量中占比较高，需要用较多的资源传输。此外，降噪业务还具有如下特点：
1、单个数据包非常小，例如有效信息可以仅为16比特(bit)、24比特或32比特；
2、时延需求非常高，例如时延需求小于或等于40微秒(μs)；
3、周期稳定，例如周期为1/48kHz(约20.83μs)。
除降噪业务外，车载通信还需要支持少量动态业务的业务数据的传输，主要用于部分对于时延需求不高的应用层信息(例如音量调节操作等相关的信息)、或设备/网络层等接入层以上各层的信令(例如上报设备故障等)。此外，物理层的传输还要支持传输接入层中的高层(如媒体接入控制(media access control，MAC)层)信令或物理层信令等。这类动态业务或信令在车载通信的总体业务量中占比很少，这类动态业务或信令的传输具有如下的共同特点：
1、数据包的大小在几十到几百比特的量级；
2、时延需求不高(毫秒级以上)，或无明确时延需求；
3、随机出现，无明显的周期性，因此动态业务可以认为是非周期性业务。
另外，车载通信还可以支持一般的音频业务、视频业务、网页浏览业务、或文件传输等业务，这些业务的数据包较大，可达几百至几千比特，这些业务的业务量在车载通信的总体业务量中占比较高。
除此之外，车载通信还需要支持系统开销的指示，其中，系统开销是指主节点与从节点之间传输系统控制信息时占用资源而产生的开销，因此，车载通信中主节点还需要指示在哪些时频资源上传输系统控制信息，以使从节点在相应的时频资源上接收系统控制信息。
通过前述介绍可知，通信域中存在多种类型的业务数据以及系统控制信息需要进行传输，不同的数据传输或信息的传输可能占用相同或不同的时频资源，目前亟需一种灵活的资源调度方式。
鉴于此，本申请实施例提供一种资源调度方法，用以节省资源调度开销，灵活实现资源调度。
本申请实施例提供的技术方案所应用的无线通信场景，可以包括广域无线通信，例如包括多个基站与多个终端设备之间的通信，其中，基站作为主节点，终端设备作为从节点，基站为终端设备分配资源，终端设备听从基站的调度。也可以包括短距离无线通信场景，例如包括CDC与车载音箱、车载麦克、手机之间的通信，手机与耳机等穿戴式设备之间的通信等。还可以包括局域无线通信，例如多个接入点(access point，AP)与多个站点(station)之间的通信等。
例如，座舱域是一种可能的短距离通信场景，本申请实施例提供的技术方案可以应用于车内的无线通信场景，则图1所示的网络架构可以是本申请实施例所应用的一种网络架构。如果将本申请实施例提供的技术方案应用于其他的广域无线通信或局域无线通信场景，则本申请实施例所应用的网络架构可以相应有所变化。
又例如，将本申请实施例提供的技术方案应用于V2X通信场景，那么可参考图2，图2为本申请实施例的一种应用场景示意图。图2所示的场景中包括终端设备1和终端设备2，终端设备1和终端设备2可通过侧行链路(sidelink，SL)通信。
再例如，将本申请实施例提供的技术方案应用于LTE系统或NR系统的Uu接口的通信，可参考图3，图3为本申请实施例的一种应用场景示意图。图3所示的场景中包括网络设备和终端设备，网络设备和终端设备可通过Uu口通信。
需要说明的是，图2和图3所示的应用场景中都以终端设备是手机为例，但本申请实 施例的终端设备不限于此。
接下来结合附图介绍本申请实施例提供的技术方案。
本申请实施例提供一种资源调度方法，图4为该方法的流程图。在下文的介绍过程中，以该方法应用于图1、图2或图3中的任一个附图所示的网络架构为例。
为了便于介绍，在下文中，以该方法由第一节点和第二节点执行为例。如果将本实施例应用在图1所示的网络架构，则下文所述的第一节点可以是图1所示的任一个通信域中的任一个从节点，例如为通信域1中的耳机，或者为通信域2中的麦克等，或者第一节点也可以是设置在图1所示的任一个通信域中的任一个从节点中的芯片系统；下文所述的第二节点可以是图1所示的任一个通信域中的任一个主节点，例如为通信域1中的手机，或者为通信域2中的CDC等，或者第二节点也可以是设置在图1所示的任一个通信域中的任一个主节点中的芯片系统。或者，如果将本实施例应用在图2所示的网络架构，则下文所述的第一节点可以是图2所示的终端设备1，下文所述的第二节点可以是图2所示的终端设备2。或者，如果将本实施例应用在图3所示的网络架构，则下文所述的第一节点可以是图3所示的终端设备，下文所述的第二节点可以是图3所示的网络设备。
其中，第一节点和第二节点位于同一个通信域中，以第一节点和第二节点位于第一通信域为例，第二节点为管理第一通信域的主节点，第一节点为第一通信域中的任意一个从节点。例如将本实施例应用在图1所示的网络架构，那么第一通信域可以是图1所示的网络架构中的任一个通信域。
S401：第二节点向第一节点发送第一消息，第二节点接收来自第一节点的第一消息；第一消息包括第一指示，第一指示用于指示第一资源的配置信息，第一资源用于传输系统控制信息和/或系统控制信号。
可选的，第一节点和第二节点可以传输系统控制信息和/或系统控制信号，当第一节点向第二节点发送系统控制信息和/或系统控制信号时，第一节点为发送端节点，第二节点为接收端节点；当第二节点向第一节点发送系统控制信息和/或系统控制信号时，第二节点为发送端节点，第一节点为接收端节点。
下面对本申请实施例中的系统控制信息和系统控制信号进一步介绍如下：
对于系统控制信息，接收端节点在接收到系统控制信息之前，并不能获知系统控制信息的具体内容，例如接收端节点可以在接收到系统控制信息之后，对系统控制信息解码，提取系统控制信息的具体内容。系统控制信息例如可以为通信系统中传输的消息或消息中的部分字段。
可选的，系统控制信息可以包括确认/否认反馈信息、广播信息、系统信息、物理层控制信息、高层控制信息、接入请求信息、调度请求信息、信道反馈信息中的至少一项；其中，确认/否认反馈信息可以为确认应答响应(acknowledge character，ACK)或否认应答响应(negative acknowledge character，NACK)，确认/否认反馈信息也可以作为一种物理层控制信息。广播信息为通过广播方式传输的系统控制信息。系统信息为用于传递通信域的相关参数或通信域中主节点的参数配置信息或公共配置参数的信息。物理层控制信息为在物理层传输的控制信息，如公共控制信令。高层控制信息为接入层中除物理层以外的其它协议层中传输的控制信息，广播信息、系统信息可以作为高层控制信息，或者也可以作为物理层控制信息。接入请求信息为用于请求接入到接收端节点的信息。调度请求信息为从 节点向主节点发送的用于请求主节点调度资源的信息。信道反馈信息为用于从节点向主节点反馈信道质量的信息。
对于系统控制信号，接收端节点在接收到系统控制信号之前，可以预先获知系统控制信号对应的序列，在接收端节点接收到系统控制信号之后，可以进行系统控制信号对应的处理。
可选的，系统控制信号可以包括同步信号、解调参考信号、相位跟踪参考信号、定位参考信号或信道状态信息参考信号、接入请求信号、调度请求信号中的至少一项。其中，同步信号为发送端节点发送的用于接收端节点与发送端节点同步的信号，例如，接收端节点在接收到同步信号后，获取发送端节点的定时信息和/或频率信息，并调整接收端节点的定时和/或频率，从而实现与发送端节点同步。解调参考信号为用于接收端节点进行信道估计和信道均衡的信号。相位跟踪参考信号为用于接收端节点跟踪传输信道的相位变化，以辅助信道估计和信道均衡的信号。定位参考信号为用于测量通信节点之间距离或确定通信节点的地理位置的信号。信道状态信息参考信号为用于进行信道质量估计的信号。接入请求信号为用于请求接入到接收端节点的信号。调度请求信号为从节点向主节点发送的用于请求主节点进行资源分配处理的信号。
可以理解的是，以上系统控制信息和系统控制信号仅作为示例，通信系统中传输的用于传递通信域的相关参数或通信域中主节点的参数配置信息或公共配置参数的控制信息或信号都可以作为本申请实施例中所述的系统控制信息或系统控制信号，本申请实施例对此不作限定。
需要说明的是，本申请实施例中系统控制信息和系统控制信号既可以以上行方式发送又可以以下行方式发送，或系统控制信息和系统控制信号只以上行方式发送或只以下行方式发送。举例来说，高层控制信息既可以以上行方式发送，也可以以下行方式发送，接入请求信息或接入请求信号只以上行方式发送，调度请求信号或调度请求信息只以上行方式发送。当然，以上对系统控制信息和系统控制信号传输方向的介绍仅作为示例，系统控制信息和系统控制信号还可以具有其它可能的传输方向定义。
一种可选的实施方式中，第一资源用于传输系统控制信息和/或系统控制信号，则第一资源为系统开销，第二节点可以通过第一消息向第一节点发送第一指示，第一指示用于指示第一资源的配置信息，第二节点接收到第一指示后，可以根据第一指示确定用于传输系统控制信息和/或系统控制信号的资源，并在该资源上接收系统控制信息和/或系统控制信号。
又一种可选的实施方式中，还可以预先为第一节点配置第一资源的配置信息，如预先配置第一资源在一个时域资源单元中占用的时域资源符号的索引以及第一资源占用的频域资源的索引。或者第一节点还可以通过协议规定确定第一资源的配置信息。
需要说明的是，本申请实施例中，在系统控制信息和/或系统控制信号的上行传输或下行传输时，第一资源可以具有相同或不同的配置信息。可以理解的是，若在系统控制信息和/或系统控制信号的上行传输和下行传输时，第一资源的配置信息不同，则第二节点可以分别对上行传输和下行传输时第一资源的配置分别进行指示，具体指示方式可以参见上述对第一指示的介绍，重复之处不再赘述。
一种可选的实施方式中，第一消息还可以包括第二指示，第二指示用于指示第三资源的配置信息，第三资源用于传输第一数据。第一数据可以为动态业务的业务数据或一般的 音频业务、视频业务、网页浏览业务或文件传输等业务的业务数据。
可选的，第一消息中包括第二指示时，第一消息可以为第二节点发送的为第一节点调度可用资源的私有调度信令，其中，可用资源可以包括本申请实施例中的第三资源。
需要说明的是，第三资源可以用于传输第一数据，但第三资源可能与第一资源重叠，则第一指示中还可以包括第三指示和/或第四指示，第三指示用于指示第三资源是否与第一资源重叠，第四指示用于指示第一重叠资源的时域符号信息，第一重叠资源为第三资源与第一资源的重叠资源。
可选的，第二节点还可以向第一节点发送第二消息，第二消息中包括第四指示，第二消息与第一消息不同，例如第二消息可以为系统信息或者高层信令。也就是说，第四指示既可以被包含在第一指示中，也可以承载在第二消息中，下面对不同场景下第四指示的具体含义进行进一步介绍：
1、当第一指示中不包括第三指示时，第四指示可以用于指示第一资源与第三资源重叠，且第一重叠资源的时域符号信息，也就是说，当第一指示中不包括第三指示时，第四指示还可以表示第一资源与第三资源重叠，第一节点在接收到第四指示后，可以直接根据第四指示确定第一重叠资源。
2、当第一指示中包含第三指示，且第三指示用于指示第一资源与第三资源重叠时，第四指示用于指示第一重叠资源的时域符号信息。当第三指示用于指示第一资源与第三资源不重叠时，第四指示所指示的第一重叠资源并不存在，则第四指示也就不能够生效。第一节点在接收到第三指示和第四指示后，需要先确定第三指示用于指示第一资源与第三资源重叠，再根据第四指示确定第一重叠资源。
下面对第三指示和第四指示占用的资源以及指示内容进行进一步介绍：
1、第三指示
第三指示可以占用第一消息中的1bit以指示第三资源是否与第一资源重叠，例如，该比特位对应的比特值为0表示第三资源与第一资源重叠，该比特位对应的比特值为1表示第三资源与第一资源不重叠。
第三指示也可以为比特图(bitmap)，在该bitmap中，不同的比特位对应的比特值可以表示该比特位对应的第三资源中的时域资源单元中是否与第一资源重叠。其中，时域资源单元可以是无线帧、子帧、时隙等，或者时域资源单元可以为多个无线帧构成的无线帧组、多个子帧构成的子帧组或多个时隙构成的时隙组等，本申请对此不作限定。例如，以时域资源单元为无线帧为例，bitmap包括6bits，当该bitmaps的比特值为010011时，表示第1、3、4个比特位对应的无线帧与第一资源重叠，第2、5、6个比特位对应的无线帧与第一资源不重叠。
可以理解的是，在不同通信系统中，作为时域资源的分配粒度，时域资源单元配置可以不同，具体的，所述时域资源单元可以为符号、无线帧、超帧等。例如在LTE系统中，一个无线帧定义为10ms，一个无线帧包含10个子帧，一个子帧定义为1ms，一个时隙定义为0.5ms。在NR系统中，一个无线帧和一个子帧的定义与LTE系统中的定义相同，也即一个无线帧定义为10ms，一个子帧定义为1ms，但NR系统中一个时隙的长度为一个可配置的值。在一种通用的短距通信系统中，一个无线帧的时长定义为1/(48kHz)(约20.83us)，进一步，一种由多个无线帧构成的无线帧组可以定义为包含设定数目个连续无线帧的超帧，例如，一个超帧时长为1毫秒(ms)，可以包括48个连续的无线帧，或者根据相应的标准 或者协议规定，一个超帧也可以包括其他固定数量或者可变数量的无线帧。
2、第四指示
假设第三资源中包含N个时域资源单元，N为正整数，第四指示可以包括以下任一项：
(1)N个时域资源单元中第一重叠资源的时域符号的总数量信息。
例如，如第四指示可以为10，则表示第三资源中第一重叠资源的时域符号的总数量为10。
(2)N个时域资源单元中，每个时域资源单元中第一重叠资源的时域符号的数量信息，其中，任意两个时域资源单元中第一重叠资源的时域符号的数量信息相同或不同。
例如，以时域资源单元为无线帧为例，假设第三资源中包含8个无线帧，即N为8，则第四指示可以为8个无线帧中，每个无线帧中第一重叠资源的时域符号的数量信息，如第四指示可以为{2,2,1,1,1,1,1,1}，则表示第1个无线帧中第一重叠资源的时域符号的数量为2，第2个无线帧中第一重叠资源的时域符号的数量为2，第3个无线帧中第一重叠资源的时域符号的数量为1…
(3)至少一个第一数量信息，以及N个时域资源单元中每个第一数量信息对应的至少一个时域资源单元的数量，其中，在任一个第一数量信息对应的至少一个时域资源单元中，每个时域资源单元中第一重叠资源的时域符号的数量信息为该第一数量信息。
例如，以时域资源单元为无线帧为例，第三资源包含的N个无线帧中，每个无线帧中包含第一重叠资源的时域符号的数量信息可能相同，例如，第一个无线帧与第二无线帧中均包含2个时域符号的第一重叠资源，则第四指示可以为至少一个第一数量信息，以及N个无线帧中每个第一数量信息对应的至少一个无线帧的数量，如当第三资源中包含8个无线帧，即N为8时，第四指示可以为{(2,2)；(1,6)}，表示第三资源中有两个无线帧中包含的第一重叠资源的时域符号的数量为2，第三资源中有6个无线帧中包含的第一重叠资源的时域符号的数量为1。
需要说明的是，第四指示可以为第一重叠资源的时域符号的数量，或者第四指示也可以为第一重叠资源的时域符号的索引，或者其它可以表示第一重叠资源的时域符号信息的参数，本申请对此不做限定。
当第四指示为第一重叠资源的时域符号的数量时，第一节点可以通过向第二节点发送系统信息或高层信令指示第一重叠资源的时域符号的分布规则，或者通过通信协议规定第一重叠资源的时域符号的分布规则，又或者为第二节点预先配置第一重叠资源的时域符号的分布规则，从而第二节点在接收到第四指示后，可以根据第四指示以及第一重叠资源的时域符号的分布规则确定第一重叠资源的时域符号。
其中，第一重叠资源的时域符号的分布规则为第三资源包含的N个无线帧中第一重叠资源的时域符号排列的规则，例如，假设每个无线帧的缺省配置为三个下行时域符号和五个上行时域符号，其中缺省配置是指未配置用于传输系统控制信息和/或系统控制信号的第一资源时每个无线帧中用于上行传输和下行传输的时域符号配置，则参考图5，第一重叠资源的时域符号的分布规则可以为，将无线帧中配置靠前的传输方向的时域符号中，靠近保护间隔(guard period，GP)的时域符号作为第一重叠资源的时域符号，具体来说，若一个无线帧中包含一个第一重叠资源的时域符号，则第一重叠资源的时域符号可以为该无线帧中的第3个时域符号，若一个无线帧中包含两个第一重叠资源的时域符号，则第一重叠资源的时域符号可以为该无线帧中的第2个时域符号和第3个时域符号。如当第四指示为 第一重叠资源的总数量，且第四指示为N+2时，则第一节点可以根据第一重叠资源的总数量以及第一重叠资源的时域符号的分布规则确定：第三资源包含的N个无线帧中，前两个无线帧中第二个时域符号和第三个时域符号为第一重叠资源的时域符号，第三个无线帧至第N个无线帧中第三个时域符号为第一重叠资源的时域符号。
需要说明的是，每个无线帧的缺省配置并不限于上述举例，例如，每个无线帧的缺省配置还可以为四个下行时域符号和四个上行时域符号。上述对无线帧的缺省配置举例均为下行传输方向的时域符号在前，上行传输方向的时域符号在后，实施中每个无线帧的缺省配置还可以为上行传输方向的时域符号在前，下行传输方向的时域符号在后，本申请对此不作限制。
当然，第一重叠资源的时域符号的分布规则同样并不限于上述举例，例如还可以为将无线帧中配置靠后的传输方向的时域符号中，靠近GP的时域符号作为第一重叠资源的时域符号；又或者将无线帧中上行传输方向的时域符号中，靠近保护间隔GP的时域符号作为第一重叠资源的时域符号；再或者将无线帧中下行传输方向的时域符号中，靠近GP的时域符号作为第一重叠资源的时域符号。
S402：第二节点通过第二资源与第一节点传输第一数据，第一节点通过第二资源传输第一数据，第二资源与第一资源不重叠。
一种可选的实施方式中，若第一指示中包括第三指示以及第四指示，则第一节点可以根据接收到的第二指示确定第三资源，根据接收到的第一指示确定第一资源，并在确定第三指示用于指示第一资源与第三资源重叠时，根据第四指示确定第一重叠资源。第一节点可以将第三资源中除第一重叠资源以外的资源作为第二资源。
可选的，第二节点可以通过第二资源与第一节点传输第一数据，例如，第二节点可以通过第二资源与第一节点传输音频业务数据。第一节点可以通过第二资源与第二节点传输第一数据，或者，第一节点可以通过第二资源与第三节点传输第一数据，其中，第三节点可以为与第一节点属于同一通信域的其它从节点。也即，本申请实施例中第二资源可以用于主节点与从节点之间的第一数据传输，还可以用于从节点与从节点之间的第一数据传输。
通过该资源调度方法，第二节点可以通过第一消息向第一节点发送第一指示，以指示第一资源的配置信息，从而能够指示用于传输系统控制信息和/或系统控制信号的资源，第二节点可以通过与第一资源不同的第二资源与第一节点传输第一数据。通过本方案，提供一种灵活的资源调度方法，第二节点通过第一消息向第一节点发送第一指示，减少资源调度的开销，并将第一消息直接发送至第一节点，提升资源调度的可靠性。
本申请实施例一种可选的实施方式中，第二节点还可以发送第五指示，第五指示用于指示属于其它通信域的第四资源的配置信息，其它通信域与第二节点管理的通信域不同。可以理解的是，其它通信域中可能也包括第二节点，但第二节点并不是其它通信域的主节点，如第二节点可以为其它通信域中的一个从节点。
可选的，第五指示可以承载于上述的第一消息或者不同与第一消息的第三消息中，下面对第二节点发送第五指示的不同方式分别进行介绍：
方式一、第一消息还包括第五指示。
可选的，第一消息中还可以包括第五指示，第五指示用于指示属于其它通信域的第四资源的配置信息，如第四资源的索引。则第一节点可以根据第五指示确定第四资源，进而 在与第二节点通信时，使用第三资源中除第四资源以外的资源传输第一数据。
方式二、第二节点发送第三消息，第三消息包括第五指示，第五指示用于指示属于其它通信域的第四资源的配置信息，第三消息与第一消息不同。
可选的，第一节点还可以通过第三消息发送第五指示，其中，第三消息可以为系统信息，或者第三消息还可以为高层信令。第五指示用于指示属于其它通信域的第四资源的配置信息，如第四资源的索引。第一节点在接收到第三消息后，可以根据第五指示确定第四资源，进而在与第二节点通信时，使用第三资源中除第四资源以外的资源发送或接收第一数据。
可以理解的是，第一节点和第二节点在通信过程中，并不会占用与第一节点和第二节点所属通信域不同的其它通信域的资源，也就是第一节点与第二节点通信中不会使用第四资源。因此，第二节点可以通过第一消息或第三消息向第一节点发送第五指示以指示第四资源，第一节点在接收到第五指示后，可以根据第五指示确定第四资源，进而第一节点可以确定第三资源中除第四资源以外的资源作为第二资源，并通过第二资源传输第一数据，防止不同通信域的资源冲突。
本申请实施例一种可选的实施方式中，第一节点与第二节点之间还需要传输满足以下特点的第二数据：
1、单个数据包非常小，例如有效信息可以仅为16比特(bit)、24比特或32比特；
2、时延需求非常高，例如时延需求小于等于40微秒(μs)；
3、周期稳定，例如周期为1/48kHz(约20.83μs)。
例如，第二数据可以为降噪业务数据。
通过上述第二数据的特点可知，第二数据的周期稳定，且时延需要非常高，则要求第二节点在调度传输第二数据的第五资源时，需要保证第一节点能够及时确定第五资源并接收第二数据。另外，并不是所有的通信域中都需要传输第二数据，以第二数据为降噪业务数据为例，许多通信域并不支持降噪业务，因此，在这些通信域中，第二节点并不需要为第一节点配置第五资源。
基于以上分析，本申请实施例一种可选的实施方式中，第二节点还可以发送第六指示，第六指示用于指示是否配置第五资源，第五资源用于传输第二数据。第一节点在接收到第六指示后，可以确定第二节点是否配置了第五资源，也即第二节点管理的通信域中是否存在第二数据对应的业务。
可选的，第六指示可以承载于第一消息或者不同于第一消息的第四消息中，下面对第二节点发送第六指示的不同方式分别进行介绍：
方式一、第一消息还包括第六指示。
可选的，第二节点向第一节点发送第一消息，第一消息中可以包括第一指示，还可以包括第六指示。
方式二、第二节点发送第四消息，第四消息包括第六指示。
可选的，第二节点可以发送第四消息，第四消息中包括第六指示，其中，第四消息可以为系统信息，或者第四消息还可以为高层信令。
一种可选的实施方式中，第二节点还可以发送第七指示，第七指示用于指示第五资源的配置信息。具体实施中，第二节点可以同时发送第六指示与第七指示，则第一节点在接 收到第六指示后，在确定第六指示用于指示第二节点配置第五资源后，第一节点可以根据第七指示确定第五资源。或者，第二节点也可以不发送第六指示，而向第一节点发送第七指示，则第一节点在收到第七指示时，可以直接根据第七指示确定第五资源，也即，第七指示也可以用于指示第二节点已配置第五资源以及指示第五资源的配置信息。
下面对本申请实施例中第二节点发送第七指示的不同方式分别进行介绍：
方式一、第一节点发送系统信息，系统信息中包括第七指示。
方式二、第一节点在一个周期内至少发送P次第五消息，第五消息包括第七指示，第七指示用于指示第五资源的配置信息；其中，一个周期包含M个超帧，M为不小于2的正整数，P为小于M的正整数。
需要说明的是，一个超帧可以定义为包括设定数目个连续的无线帧，例如一个超帧可以包括48个连续的无线帧。
可选的，第五消息可以为物理层信令，例如第五消息可以为公共控制信令，公共控制信令是第二节点以广播方式发送的，用于向第二节点管理的通信域内的从节点发送指示信息的信令。
一种可选的实施方式中，由于第二数据的周期较为稳定，则可以将M个超帧作为一个周期，在一个周期内，第二节点向第一节点发送一次或多次第五消息，以指示下一周期中第五资源的配置信息，则将一个周期作为第五资源的变更周期。其中，第二节点向第一节点多次发送第五消息时，第二次之后发送的第五消息可以作为第一次发送的第五消息的重发消息，从而第一节点在接收到多次第五消息后，可以进行比较验证首次接收到的第五消息是否准确，进而提高第五资源指示方法的准确性。
需要说明的是，一个周期包含M个超帧时，若第一节点在一个周期内发送P次第五消息，则P为小于M的正整数，也就是说，一个周期内，第二节点发送第五消息的次数不能大于该周期内包括的超帧数目。
可选的，当第二节点通过第五消息发送第七指示时，第二节点还可以指示第五消息的配置信息，具体可以为：
1、第二节点发送第六资源的配置信息或者用于指示第六资源的配置信息的指示信息，第六资源用于传输所述第五消息。
可选的，第二节点在发送第五消息之前，可以向第一节点发送用于传输第五消息的第六资源的配置信息或者用于指示第六资源的配置信息的指示信息，从而使得第一节点在接收到第六资源的配置信息或者用于指示第六资源的配置信息的指示信息后，能够确定第六资源，从而在第六资源上接收第五消息。
其中，第二节点可以直接向第一节点发送第六资源的配置信息，或者第二节点向第一节点发送第六资源的配置信息的指示信息。例如，第二节点可以直接向第一节点发送第六资源的时频域资源信息(如时频域资源索引)，或者第二节点可以向第一节点发送第六资源的配置信息的指示信息，例如预先为第一节点配置多组第六资源的配置信息，第二节点可以向第一节点发送第六资源的配置信息的指示信息，如第六资源的配置信息的指示信息可以为一组第六资源的配置信息的索引值，第一节点接收到第二节点发送的第六资源的配置信息的指示信息后，可以从多组第六资源的配置信息中确定第二节点本次传输第五消息时使用的第六资源的配置信息。
2、第二节点发送第一数量信息或者第一数量信息的指示信息；第一数量信息用于指 示一个周期内包含的超帧数量M。
其中，第一数量信息例如可以为数量M，或者可以为一个周期内超帧的索引，也就是说，第一数量信息的具体形式本申请不做限定，可以表示一个周期内包含的超帧数量M的信息均适用。
举例来说，第二节点可以直接将一个周期内包含的超帧数量M作为第一数量信息，并将第一数量信息发送给第一节点，或者，预先为第一节点配置第一数量信息集合(如可以为数量信息表格)，第二节点向第一节点发送一个指示信息，该指示信息可以包括索引值，第一节点在接收到该指示信息后，可以根据该指示信息中包括的索引值，从预先配置的第一数量信息集合中查找该索引值对应的第一数量信息，进而确定一个周期内包含的超帧数量M。
又一种实施方式中，第一数量信息还可以预先配置至第一节点，或者由协议规定第一数量信息。
3、第二节点发送第二数量信息或者第二数量信息的指示信息；第二数量信息用于指示一个周期内发送第五消息的次数P。
举例来说，第二节点可以将一个周期内发送第五消息的次数P作为第二数量信息，并将第二数量信息发送给第一节点，或者，预先为第一节点配置多个第二数量信息，第二节点可以发送用于指示第二数量信息的指示信息，如该指示信息可以第二数量信息的索引值，第一节点在接收到该指示信息后，可以根据该指示信息中包括的索引值，从预先配置的多个第二数量信息中查找该索引值对应的第二数量信息，进而确定一个周期内发送第五消息的次数P。
一种可选的实施方式中，第二节点可以分别通过不同的消息发送以上多个第五消息的配置信息，例如，第二节点发送第六消息，第六消息中包括第六资源的配置信息或者用于指示第六资源的配置信息的指示信息；第二节点发送第七消息，第七消息中包括第一数量信息或者第一数量信息的指示信息；第二节点发送第八消息，第八消息中包括第二数量信息或者第二数量信息的指示信息。又或者，第二节点可以将多个第五消息的配置信息集成在一个或多个消息中，也就是说，第五消息的配置信息可以为一个复用的联合指示信息，在该联合指示信息中可以包括上述的三种第五消息的配置信息。当然，其它能够实现第五消息的配置信息指示的方式也适用，本申请对此不做限制。
可以理解的是，第五资源用于传输第二数据，则第二节点与第一节点进行通信时，若存在第二数据需要进行传输，则第二节点与第一节点传输第一数据时不会占用第五资源。因此，第一节点在接收到第六指示后，若确定第六指示用于指示配置第五资源，则第一节点根据接收到的第七指示确定第五资源的配置信息，进而确定第五资源，第一节点可以通过第五资源传输第二数据。需要注意的是，若第五资源与第三资源存在重叠，则第一节点需要确定第三资源中除与第五资源重叠的资源之外的资源作为第二资源，再通过第二资源传输第一数据。
