Description

一种调度方法、装置及系统 技术领域
本申请涉及移动通信技术领域，尤其涉及一种调度方法、装置及系统。
背景技术
车载应用的多样化，使得车内通信节点数量、类型都越来越多，对于车载通信的能力提出了更高的要求。通常，车内的通信链路可包括多个通信域，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。
目前对于一个通信域来说，主节点可以发送调度信令，以调度从节点传输业务数据。其中的每个从节点被配置一组固定的资源用于接收调度信令，主节点在调度从节点时从这一组资源中选择一个资源发送调度信令，从节点会在这一组资源中的每个资源上盲检调度信令。调度信令可以指示所调度的传输数据的资源、传输数据的调制编码方式(modulation and coding scheme，MCS)、传输数据的类型、以及功率控制等信息。
可见，调度信令所包括的内容较多，信息量较大。而一般来讲，在使用同样多的资源的情况下，传输的信息越多，则传输可靠性越低。可见，目前由于调度信令包括的内容较多，导致调度信令传输的可靠性较低。
发明内容
本申请实施例提供一种调度方法、装置及系统，用于提高调度信令传输的可靠性。
第一方面，提供第一种调度方法，该方法包括：第一通信装置在第一资源发送第一信令，所述第一信令用于指示N个通信装置，N为大于或等于1的整数；所述第一通信装置在第二资源发送第二信令，所述第二信令用于调度所述N个通信装置发送或接收第一数据，所述第一资源与所述第二资源具有关联关系。
该方法可由第一通信装置执行，第一通信装置可以是通信设备或能够支持通信设备实现该方法所需的功能的通信装置，例如芯片。示例性地，所述第一通信装置为终端装置，该终端装置为终端设备，或者为设置在终端设备中的用于实现终端设备的功能的芯片，或者为用于实现终端设备的功能的其他部件。
在本申请实施例中，可以实现两级调度方式，第一信令只需指示相应的通信装置，无需包括过多的信息，使得第一信令的信息量较小。而且由于第一信令已经指示了相应的通信装置，第二信令无需再指示通信装置，可见，作为调度信令而言，第一信令和第二信令的信息量都是有所减少的，由此可以提高调度信令的传输可靠性。各通信装置在盲检时，由于第一信令的信息量较小，因此盲检量也比较小。而一个通信装置在检测到第一信令后就可以确定该通信装置是否被调度，从而未被调度的通信装置不必再检测第二信令，可减少这些未被调度的通信装置的无效盲检。另外，第一资源与第二资源具有关联关系，那么第一信令和第二信令的接收端(例如第二通信装置)在确定第一资源后就可以确定第二资源，从而在第二资源上检测第二信令即可，无需在过多的资源上盲检，由此可以进一步节 省通信装置的盲检量，简化通信装置的实现复杂度。
在一种可选的实施方式中，所述方法还包括：
所述第一通信装置在第三资源发送第三信令，所述第三信令用于指示M个通信装置，M为大于或等于1的整数；
所述第一通信装置在第四资源发送第一信号，所述第一信号包括第二数据、第一高层信令、或参考信号中的至少一个，所述第三资源与所述第一资源属于第一组资源，所述第二资源与所述第四资源属于第二组资源，所述第一组资源所包括的资源与所述第二组资源所包括的资源一一关联，所述第三资源与所述第四资源具有关联关系。
对于动态业务、高层信令或参考信号等，可能发生较为随机，周期性不强，如果采用如前所述的两级调度模式，可能会导致调度信令的数量较多。为此，本申请实施例针对动态业务(例如第一数据对应的业务为动态业务)、高层信令或参考信号等，可采用一级调度模式，第三信令可以作为调度信令，第一通信装置在发送调度信令后就可以发送该调度信令所调度的动态业务、第一高层信令或参考信号。一级调度的方式有助于减少调度信令的数量，节省信令开销。调度信令只需指示相应的通信装置，无需指示过多内容，使得调度信令的信息量较小，即使第一通信域中的各个通信装置都要盲检调度信令，但因为信息量较小，因此盲检量也不会很大。在调度动态业务、高层信令或参考信号时，虽然是使用一级调度模式，但调度过程类似于两级调度的过程，例如也可以从第一组资源中选择资源来发送调度信令，以及从第二组资源中选择相应的资源发送第一信号，使得一级调度过程和两级调度过程统一，简化了整体的数据调度流程。另外，动态业务、高层信令或参考信号可以与第二级调度信令复用资源(这里是指，都可以使用第二组资源)，由此也提高了资源的利用率。
在一种可选的实施方式中，所述方法还包括：所述第一通信装置接收来自所述N个通信装置中的第二通信装置的第一反馈信息，所述第一反馈信息用于指示所述第一信号接收成功或接收失败。
N个通信装置中的部分通信装置或全部通信装置中的每个通信装置接收第一信号后可以向第一通信装置发送反馈信息，例如称为第一反馈信息，则第一通信装置可以接收来自N个通信装置中的部分通信装置或全部通信装置中的每个通信装置的第一反馈信息，第一反馈信息可以指示第一信号接收成功或接收失败。例如第二通信装置向第一通信装置发送了第一反馈信息，则第一通信装置可以接收来自第二通信装置的第一反馈信息。例如第一反馈信息为物理层的反馈，例如为ACK或NACK，或者第一反馈信息也可以是高层的反馈，对于反馈信息的类型不做限制。
在一种可选的实施方式中，所述参考信号用于实现如下的一种或多种功能：
时间同步；
频率同步；
相位跟踪；
信道质量探测；
信道估计；或，
干扰测量。
例如，参考信号可实现时间同步功能；或者，参考信号可实现频率同步功能；或者，参考信号可实现相位跟踪功能；或者，参考信号可实现信道质量探测功能；或者，参考信 号可实现信道估计功能；或者，参考信号可实现干扰测量功能；或者，参考信号可实现信道质量探测功能和信道估计功能，等等。或者参考信号还可以实现其他功能，本申请实施例对于参考信号能够实现的功能不做限制。这里所述的参考信号能够实现的功能，是指第二通信装置对该参考信号加以利用(例如对该参考信号进行测量)所能实现的功能。
在一种可选的实施方式中，
所述第一资源与所述第二资源的关联关系为预配置的；或，
所述方法还包括：所述第一通信装置发送第四信令，所述第四信令用于指示所述第一资源与所述第二资源的关联关系。
在本申请实施例中，可以为第一通信域预先设置第一组资源和第二组资源，第一组资源包括至少一个资源，第二组资源也包括至少一个资源，第一组资源所包括的资源与第二组资源所包括的资源具有关联关系。例如第一资源属于第一组资源，第二资源属于第二组资源，第一资源和第二资源具有关联关系。第一组资源和第二组资源，以及资源之间的关联关系等，可以或者通过协议规定；或者也可以预配置在通信装置(例如第一通信域包括的全部或部分通信装置)中，其中，要在一个通信装置中预配置相应的信息，可以在该通信装置出厂、维修或保养时将相应的信息配置在该通信装置中；或者也可以由第一通信装置设置。如果由第一通信装置设置，例如第一通信装置可以根据第一通信装置的性能(例如第一通信装置对于信息的处理时间等)确定哪两个资源可以具有关联关系，且第一通信装置在设置后可以向第一通信域内除第一通信装置外的其他通信装置发送信令，以指示第一组资源和第二组资源之间的关联关系。
在一种可选的实施方式中，所述第一信令指示所述N个通信装置，包括：
所述第一信令包括所述N个通信装置的标识；或，
用于加扰所述第一信令的扰码为第一扰码，所述第一扰码与所述N个通信装置对应。
第一信令指示N个通信装置，可以隐式指示，也可以显式指示。例如一种隐式指示的方式为，用于加扰第一信令的扰码不同，则指示的通信装置不同，例如，用于加扰第一信令的扰码为第一扰码，第一扰码对应于N个通信装置，因此第一信令能够指示N个通信装置。例如扰码1对应于通信装置1，扰码2对应于通信装置2。那么，如果用于加扰第一信令的扰码为扰码1，则表明指示通信装置1，如果用于加扰第一信令的扰码为扰码2，则表明指示通信装置2。那么，一个通信装置如果通过扰码1检测第一信令成功，则可以确定第一信令指示通信装置1，而如果通过扰码2检测第一信令成功，则可以明确第一信令指示通信装置2。通过隐式方式来指示N个通信装置，无需在第一信令中携带额外的信息指示N个通信装置，有助于节省第一信令的开销，减小N个通信装置的盲检量。而且一般来讲，在使用同样多的资源的情况下，传输的信息越少，则传输可靠性越高。那么，由于无需在第一信令中携带额外的信息指示N个通信装置，相当于用同样多的资源传输了较少的信息，由此可以提升第一信令的传输可靠性。
或者，第一信令指示N个通信装置，也可以显式指示。例如一种显式指示的方式为，第一信令包括一个通信装置的标识，就表明指示了该通信装置。那么例如第一信令包括N个通信装置的标识，就表明指示了N个通信装置。本申请实施例所述的一个通信装置的标识，例如为该通信装置的ID，或者也可以是该通信装置在第一通信域中的地址，或者也可以是该通信装置所属的通信装置组的标识等，其中，一个通信装置组对应一个标识，一个通信装置组可以包括一个或多个通信装置。如果第一信令通过隐式方式指示一个通信装置， 那么对于第一通信域内的一个通信装置来说，如果检测第一信令失败，则该通信装置很可能无法区别检测失败是因为该通信装置未被调度，还是因为检测过程导致的检测失败，则可能导致该通信装置无法确定是否要继续检测后续的第二信令。而显式指示的方式就可以避免这种问题，各个通信装置都可以盲检第一信令，如果第一信令包括一个通信装置的标识，该通信装置就可以明确自身被调度，而如果第一信令不包括一个通信装置的标识，该通信装置就可以明确自身未被调度，使得通信装置后续的处理逻辑更为清晰。
在一种可选的实施方式中，所述第一信令为物理层信令。
第一信令的作用是让相应的通信装置知晓该通信装置被调度，例如第一信令指示N个通信装置，就表明这N个通信装置被调度。物理层信令的处理流程短，因此处理速度快，因此如果第一信令为物理层信令，则相应的通信装置可以快速确定自身是否被调度。或者第一信令也可以是其他信令，例如高层信令等，本申请实施例不做限制。
在一种可选的实施方式中，所述第二信令为高层信令。
在两级调度过程中，由于第二信令需要调度第一数据，因此第二信令包括的内容可能较多，较为复杂。因此可选的，第二信令例如为高层信令，例如RRC信令或MAC CE等。高层信令的容量较大，可以包括较多的信息。或者，第二信令也可以是其他信令，例如物理层信令等，本申请实施例对此不做限制。
在一种可选的实施方式中，所述第二信令还包括所述第二信令的类型信息和/或所述第二信令的数据量信息。
第二信令的类型信息和/或所述第二信令的数据量信息可以包括在第二信令中。通过这种方式，可以减小第一信令的数据量，使得通信装置对于第一信令的盲检量进一步减小。
在一种可选的实施方式中，所述第一信令还包括如下的一种或多种信息：
所述第二信令的MCS；
所述第二信令的类型信息；
所述第二信令的优先级信息；或，
所述第二信令的数据量信息。
第二信令的MCS是第二信令的调制编码方式，可包括第二信令的调制方式，或包括第二信令的编码方式，或包括第二信令的调制方式和编码方式。第一信令如果包括第二信令的MCS，则N个通信装置根据该MCS接收第二信令即可，无需使用多种MCS盲检第二信令，减少N个通信装置的盲检量。如果第一信令包括第二信令的类型信息，则N个通信装置在解析第二信令时无需通过盲检的方式解析，而是可以直接解析，这减少了N个通信装置的盲检量。第二信令的类型，例如指示如下信息中的一种或多种：第二信令是何种类型的信令(例如调度信令、载波切换信令或用于指示上报信道信息的信令等)，第二信令的调度类型(例如半静态调度类型或动态调度类型)，或，第二信令的优先级。其中，如果第二信令的类型仅指示第二信令的优先级(或者说，第二信令的类型信息仅包括第二信令的优先级信息)，那么第二信令的类型信息和第二信令的优先级信息可以认为是同种信息，在这种情况下，该信息可以称为第二信令的类型信息，也可以称为第二信令的优先级信息。如果第一信令包括第二信令的数据量信息，则N个通信装置在解析第二信令时也无需通过盲检的方式解析，而是可以直接解析，这也减少了N个通信装置的盲检量。
在一种可选的实施方式中，所述第一数据是使用半静态调度的方式调度的。
第一数据例如对应于第一业务，例如第一数据也可称为第一业务数据。第一业务可以 是动态业务，或者也可以是非动态业务。如果第一业务是非动态业务，那么第一业务的调度方式例如为半静态调度方式。第一数据对应于第一业务，则第一数据就可以使用半静态调度方式来调度。例如第二信令的类型信息还指示第二信令的调度类型，那么第二信令的调度类型可以是半静态调度类型。或者，虽然第一业务是非动态业务，但第一业务也可以不采用半静态调度方式而是采用其他调度方式来调度，或者，如果第一业务是动态业务，则第一业务同样可以不采用半静态调度方式而是采用其他调度方式来调度，那么第一数据就不使用半静态调度方式调度。本申请实施例对于第一数据的调度方式不做限制。
例如，第一数据仅为非动态业务，且仅使用半静态调度方式来调度，对于动态业务(例如第一信号可对应动态业务)则使用前文所述的一级调度模式来调度。这样可以减少第二信令的类型，简化调度信令(例如第二信令)。并且，由于可用于传输第一数据的资源仅使用半静态调度方式调度，也可以避免可用于传输第一数据的资源碎片化。
在一种可选的实施方式中，所述第二信令包括如下的一种或多种信息：
用于发送或接收所述第一数据的时域资源信息和/或频域资源信息；
所述第一数据的MCS；
所述第一数据的类型信息；或，
用于发送所述第一数据的功率控制信息。
第二信令可以指示第一数据的资源或MCS等，从而N个通信装置能够正确接收或发送第一数据。当然第二信令还可以指示与第一数据有关的其他信息，具体不做限制。
在一种可选的实施方式中，所述方法还包括：
所述第一通信装置发送或接收所述第一数据。
如果第二信令是调度N个通信装置接收来自第一通信装置的第一数据，那么第一通信装置在发送第二信令后，还可以按照第二信令向N个通信装置发送第一数据，N个通信装置可根据第二信令接收来自第一通信装置的第一数据。或者，如果第二信令是调度N个通信装置向第一通信装置发送第一数据，那么N个通信装置在接收第二信令后，还可以按照第二信令向第一通信装置发送第一数据，第一通信装置可根据第二信令接收来自N个通信装置中的每个通信装置的第一数据。
在一种可选的实施方式中，所述方法还包括：
所述第一通信装置接收来自所述N个通信装置中的第二通信装置的第二反馈信息，所述第二反馈信息用于指示所述第二信令接收成功或接收失败。
N个通信装置接收第二信令后，N个通信装置中的部分通信装置或全部通信装置中的每个通信装置可以向第一通信装置发送反馈信息，例如称为第二反馈信息，则第一通信装置可以接收来自N个通信装置中的部分通信装置或全部通信装置中的每个通信装置的第二反馈信息，第二反馈信息可以指示第二信令接收成功或接收失败。例如第二通信装置向第一通信装置发送了第二反馈信息，则第一通信装置可接收来自第二通信装置的第二反馈信息。例如第二反馈信息为物理层的反馈，例如为ACK或NACK，或者第二反馈信息也可以是高层的反馈，对于反馈信息的类型不做限制。
在一种可选的实施方式中，所述方法还包括：
所述第一通信装置在第五资源发送第五信令，所述第五信令用于指示不调度任意通信装置在第六资源接收信号，所述第五资源与所述第一资源属于第一组资源，所述第二资源属于第二组资源，所述第一组资源所包括的资源与所述第二组资源所包括的资源一一关联， 所述第二组资源包括与所述第五资源具有关联关系的所述第六资源。
如果一个通信装置接收了第五信令，可以确定自身还处于第一通信域的范围内，从这个意义上来讲，第五信令可以视为一种心跳信息，可以使得通信装置明确是否移动出了一个通信域的范围，从而通信装置可以采取相应的应对策略。例如对于图1A所示的网络架构来说，手机可作为通信域2的一个从节点，手机由用户持有，可能会发生移动。例如通信域2内的主节点CDC会周期性发送第五信令，如果手机在某个周期或某几个周期内未检测到第五信令，手机就可以确定已移动出了通信域2的范围，则手机可以重新与通信域2建立连接，或者选择与其他通信域建立连接等。
在一种可选的实施方式中，所述第五信令用于指示不调度任意通信装置在第六资源接收信号，包括：
所述第五信令包括第一标识，第一标识不是任何一个通信装置或通信装置组的标识。
第一标识例如为通信装置的标识，例如通信装置的ID。但第一标识可以是缺省标识，或者说第一标识为保留标识，对此可理解为，第一标识所指示的通信装置并不存在，或者至少在第一通信域中不存在。或者，第一标识例如为通信装置组的标识，例如通信装置组的ID。但第一标识可以是缺省标识，或者说第一标识为保留标识，对此可理解为，第一标识所指示的通信装置组并不存在，或者至少在第一通信域中不存在。那么对于接收了第五信令的一个通信装置来说，可以确定第五信令不调度任何通信装置或通信装置组在第六资源接收信号，或者，可以确定第五信令不调度该通信装置在第六资源接收信号。
第二方面，提供第二种调度方法，该方法包括：第二通信装置在第一资源接收第一信令，所述第一信令用于指示N个通信装置，N为大于或等于1的整数；所述N个通信装置包含所述第二通信装置，所述第二通信装置在与所述第一资源具有关联关系的第二资源接收第二信令，所述第二信令用于调度所述N个通信装置发送或接收第一数据。

具体实施方式
本申请实施例的说明书和权利要求书及上述附图中的术语“第一”、“第二”、“第三”、“第四”等(如果存在)是用于区别类似的对象，而不必用于描述特定的顺序或先后次序。应该理解这样使用的数据在适当情况下可以互换，以便这里描述的本申请的实施例能够以除了在这里图示或描述的那些以外的顺序实施。此外，术语“包括”和“具有”以及他们的任何变形，意图在于覆盖不排他的包含，例如，包含了一系列步骤或单元的过程、方法、系统、产品或设备不必限于清楚地列出的那些步骤或单元，而是可包括没有清楚地列出的或对于这些过程、方法、产品或设备固有的其它步骤或单元。

下面首先对本申请实施例涉及的部分用语进行解释说明，以便于本领域技术人员理解。
(1)座舱域控制器(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(controller area network，CAN)-总线(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。
(2)主节点、从节点，在逻辑功能上区分的两类节点，分别是主节点和从节点。其中主节点管理从节点，具有分配资源的功能，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与主节点进行通信。节点可以为各种装置，例如主节点为手机，从节点为耳机，手机与耳机建立通信连接实现数据交互。手机管理耳机，手机具有分配资源的功能，可以为耳机分配资源。
(3)通信域，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。其中，一个装置或设备可以在多个通信域中。例如当手机与耳机进行无线通信时，手机在包括手机与耳机在内的通信域a中，在通信域a中手机为主节点，耳机为从节点；然后当手机检测到CDC，并与该CDC建立无线连接后，手机也在包括手机与CDC在内的通信域b中，在通信域b中CDC为主节点，手机为从节点，手机听从该CDC的调度。 通信域b中还可以包括其他从节点，如车载音箱、麦克等。
(4)本申请实施例中的术语“系统”和“网络”可被互换使用。“至少一个”是指一个或者多个，“多个”是指两个或两个以上。“和/或”，描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B的情况，其中A,B可以是单数或者复数。字符“/”一般表示前后关联对象是一种“或”的关系。“以下至少一项(个)”或其类似表达，是指的这些项中的任意组合，包括单项(个)或复数项(个)的任意组合。例如，a,b,或c中的至少一项(个)，可以表示：a,b,c,a-b,a-c,b-c,或a-b-c，其中a,b,c可以是单个，也可以是多个。
以及，除非有相反的说明，本申请实施例提及“第一”、“第二”等序数词是用于对多个对象进行区分，不用于限定多个对象的大小、内容、顺序、时序、优先级或者重要程度等。例如，第二信令和第二信令，只是为了区分不同的信令，而并不是表示这两个信令的大小、内容、发送顺序、优先级或者重要程度等的不同。
前文介绍了本申请实施例所涉及到的一些名词概念，下面介绍本申请实施例涉及的技术特征。
车载应用的多样化，使得车内通信节点数量、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，这使得车载通信技术有逐步向无线化发展的趋势。
通常，车内通信链路的拓扑关系如图1A所示。从图1A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1A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；PEPS、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，其中无钥匙进入及启动系统(passive entry passive start，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、信令以及一些信号(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1A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，例如时延需求约20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消息(例如音量调节操作等相关的消息)、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。
除此之外，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。
目前对于一个通信域来说，如果从节点需要发送或接收业务数据，主节点需要为从节点进行调度，例如调度用于传输该业务数据的资源等。例如一个通信域中，主节点可以发送调度信令，以调度从节点传输业务数据。该通信域的每个从节点都被配置一组固定的资源用于接收调度信令，主节点在调度从节点时从这一组资源中选择一个资源发送调度信令，该通信域的每个从节点会在这一组资源中的每个资源上盲检调度信令。调度信令可以指示所调度的传输数据的资源、传输数据的MCS、传输数据的类型、以及功率控制等信息。可以看到，调度信令所包括的内容较多，信息量较大，而一个通信域中的每个从节点都可能需要盲检调度信令，从节点的盲检量较大，导致节点的实现复杂度较高，功耗也较大。
另外，调度信令可以有不同的类型，例如动态调度类型或半静态调度(semi-persistent scheduling，SPS)类型等。不同的调度类型对应不同的调度信令，不同的调度信令指示的信息和占用的资源也不同，从节点需要盲检多种类型的调度信令。另外，可能同一个资源会被不同的从节点复用，那么主节点可以通过调度信令的循环冗余校验(cyclic redundancy check，CRC)或扰码等隐式指示调度信令所指示的从节点。可见，目前调度信令的发送和接收机制都较为复杂，主节点和从节点的实现复杂度较高。而且一般来讲，在使用同样多的资源的情况下，传输的信息越多，则传输可靠性越低。可见，目前由于调度信令包括的内容较多，导致调度信令传输的可靠性较低。
鉴于此，提供本申请实施例的技术方案。在本申请实施例中，可以实现两级调度方式，第一信令只需指示相应的通信装置，无需包括过多的信息，使得第一信令的信息量较小。而且由于第一信令已经指示了相应的通信装置，第二信令无需再指示通信装置，可见，作为调度信令而言，第一信令和第二信令的信息量都是有所减少的，由此可以提高调度信令的传输可靠性。各通信装置在盲检时，由于第一信令的信息量较小，因此盲检量也比较小。而一个通信装置在检测到第一信令后就可以确定该通信装置是否被调度，从而未被调度的通信装置不必再检测第二信令，可减少这些未被调度的通信装置的无效盲检。另外，第一资源与第二资源具有关联关系，那么第一信令和第二信令的接收端(例如第二通信装置)在确定第一资源后就可以确定第二资源，从而在第二资源上检测第二信令即可，无需在过多的资源上盲检，由此可以进一步节省通信装置的盲检量，简化通信装置的实现复杂度，进一步也可以减小通信装置的功耗。
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。也可以包括车内无线通信场景，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，将本申请实施例提供的技术方案应用于车内的无线通信场景，则图1A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1B，为本申请实施例的一种应用场景。图1B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1C，为本申请实施例的一种应用场景。图1C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。
图1B和图1C都以终端设备是手机为例，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调度方法，请参见图2，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1A～图1C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，以该方法由第一通信装置和第二通信装置执行为例。如果将本实施例应用在图1A所示的网络架构，则下文所述的第二通信装置可以是图1A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，或者第二通信装置也可以是设置在图1A所示的任一个通信域中的任一个从节点中的芯片系统；下文所述的第一通信装置可以是图1A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，或者第一通信装置也可以是设置在图1A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1B所示的网络架构，则下文所述的第一通信装置可以是图1B所示的终端设备1，下文所述的第二通信装置可以是图1B所示的终端设备2。或者，如果将本实施例应用在图1C所示的网络架构，则下文所述的第一通信装置可以是图1B所示的网络设备，下文所述的第二通信装置可以是图1B所示的终端设备。
其中，第一通信装置和第二通信装置可位于同一个通信域中，例如将该通信域称为第一通信域。例如将本实施例应用在图1A所示的网络架构，那么第一通信域可以是图1A所示的网络架构中的任一个通信域。需要注意的是，如果将本实施例应用在图1A所示的网络架构，则第一通信域并不是特指图1A中的通信域1，而是指图1A所示的网络架构中的任一个通信域。
S21、在第一资源发送第一信令，步骤S21可以由第一通信装置执行，第一通信装置所在的通信域中的至少一个通信装置在第一资源接收来自第一通信装置的第一信令，这至少一个通信装置包括第二通信装置，图2以第二通信装置接收第一信令为例。第一信令可以指示N个通信装置，这N个通信装置可以是第一通信域内除第一通信装置外的全部或部分通信装置，N为大于或等于1的整数。
在本申请实施例中，可以为第一通信域预先设置第一组资源和第二组资源，第一组资源包括至少一个资源，第二组资源也包括至少一个资源，第一组资源所包括的资源与第二组资源所包括的资源具有关联关系，例如第一组资源与第二组资源可以是一一对应的关系，或者说是一一关联的关系。这里的一一对应是指，对于第一组资源中的任意一个资源，第二组资源中存在唯一的一个资源与之对应，并且对于第二组资源中的任意一个资源，第一组资源中存在唯一的一个资源与之对应。例如，第一组资源包括的第一资源在第二组资源里唯一对应第二资源，而第二组资源所包括的第二资源在第一组资源里也唯一对应第一资源。
或者，第一组资源所包括的资源与第二组所包括的资源具有关联关系，这种关联关系也可以不是一一对应的关系。例如，对于第一组资源中的任意一个资源，第二组中都存在P个资源与之对应。对于这种情况，第一信令还可以指示第二信令在这P个资源中的哪一个资源上发送，或第一信令不指示第二信令具体在这P个资源中的哪个资源上发送，则N个通信装置可以在P个资源上盲检第二信令。P为大于或等于1的整数。在本申请实施例后文的描述过程中，主要以第一组资源与第二组资源一一对应为例。
如果第一通信装置选择了第一组资源中的一个资源(例如资源1)发送了第一信令，那么第一通信装置在发送第一信令对应的信息(例如后文将要介绍的第二信令或第一信号)时，就会选择第二组资源中与资源1具有关联关系的第二资源来发送。其中，这里的一组资源，只是为了表明包括至少一个资源，在设置时可以以“组”或“集合”的形式来设置，或者也可以没有“组”或“集合”的概念，只是设置了至少一个资源。第一组资源和第二组资源，以及资源之间的关联关系等，可以或者通过协议规定；或者也可以预配置在通信装置(例如第一通信域包括的全部或部分通信装置)中，其中，要在一个通信装置中预配置相应的信息，可以在该通信装置出厂、维修或保养时将相应的信息配置在该通信装置中；或者也可以由第一通信装置设置。如果由第一通信装置设置，例如第一通信装置可以根据第一通信装置的性能(例如第一通信装置对于信息的处理时间等)确定哪两个资源可以具有关联关系，且第一通信装置在设置后可以向第一通信域内除第一通信装置外的其他通信装置发送信令，以指示第一组资源和第二组资源之间的关联关系。
可选的，第一资源例如包括至少一个子资源，这至少一个子资源可以是时域上连续的资源，或者这至少一个子资源在时域上均不连续，或者这至少一个子资源中至少有两个相邻的子资源(例如至少一个子资源中，在时域上的第i个子资源和第(i+1)个子资源)在时域上不连续。另外，至少一个子资源可以是频域上连续的资源，或者这至少一个子资源在频域上均不连续，或者这至少一个子资源中至少有两个相邻的子资源(例如至少一个子资源中，在频域上的第j个子资源和第(j+1)个子资源)在频域上不连续。对于后文将要介绍的第二资源、第三资源、第四资源、第五资源、第六资源或第七资源中的一个或多个，都可以是与第一资源类似的情况。或者理解为，对于第一组资源所包括的全部资源或部分资源，可以是与第一资源类似的资源；对于第二组资源所包括的全部资源或部分资源，可以是与第一资源类似的资源；对于后文将要介绍的第三组资源所包括的全部资源或部分资源，可以是与第一资源类似的资源。在后文中均不再多赘述。
第一通信装置要发送第一信令，就可以从第一组资源中选择一个资源来发送，例如选择了第一资源。第一信令例如为物理层信令，例如下行控制信息(downlink control information，DCI)，或者也可以是其他的物理层信令。第一信令的作用是让相应的通信装 置知晓该通信装置被调度，例如第一信令指示N个通信装置，就表明这N个通信装置被调度。物理层信令的处理流程短，因此处理速度快，因此如果第一信令为物理层信令，则相应的通信装置可以快速确定自身是否被调度。或者第一信令也可以是其他信令，例如高层信令等，本申请实施例不做限制。其中，本申请实施例所述的高层信令例如为无线资源控制(radio resource control，RRC)信令，或MAC控制元素(control element，CE)等。
第一信令指示N个通信装置，可以隐式指示，也可以显式指示。
例如，一种隐式指示的方式为，第一信令所占用的资源不同，则所指示的通信装置不同，例如，用于发送第一信令的第一资源与N个通信装置对应，因此第一信令能够指示N个通信装置。例如第一组资源包括资源1和资源2，资源1对应通信装置1和通信装置2，资源2对应通信装置3，如果第一信令通过资源1发送，则表明指示通信装置1和通信装置2，如果第一信令通过资源2发送，则表明指示通信装置3。那么，如果一个通信装置在资源1检测到第一信令，就可以明确第一信令指示通信装置1和通信装置2，而如果一个通信装置在资源2检测到第一信令，就可以明确第一信令指示通信装置3。
又例如，一种隐式指示的方式为，用于加扰第一信令的扰码不同，则指示的通信装置不同，例如，用于加扰第一信令的扰码为第一扰码，第一扰码对应于N个通信装置，因此第一信令能够指示N个通信装置。例如扰码1对应于通信装置1，扰码2对应于通信装置2。那么，如果用于加扰第一信令的扰码为扰码1，则表明指示通信装置1，如果用于加扰第一信令的扰码为扰码2，则表明指示通信装置2。那么，一个通信装置如果通过扰码1检测第一信令成功，则可以确定第一信令指示通信装置1，而如果通过扰码2检测第一信令成功，则可以明确第一信令指示通信装置2。
再例如，一种隐式指示的方式为，第一信令使用的CRC不同，则指示的通信装置不同，例如，第一信令的CRC为第一CRC，第一CRC对应于N个通信装置，因此第一信令能够指示N个通信装置。例如，CRC1对应通信装置1、通信装置2和通信装置3，CRC2对应通信装置4和通信装置5。那么，如果第一信令的CRC为CRC1，则表明指示通信装置1、通信装置2和通信装置3，而如果第一信令的CRC为CRC2，则表明指示通信装置4和通信装置5。那么，一个通信装置如果通过CRC1检测第一信令成功，则可以确定第一信令指示通信装置1、通信装置2和通信装置3，而如果通过CRC2检测第一信令成功，则可以确定第一信令指示通信装置4和通信装置5。
或者第一信令还可以通过其他的隐式指示方式指示N个通信装置，如上只是举例，并不是对隐式指示方式的限制。通过隐式方式来指示N个通信装置，无需在第一信令中携带额外的信息指示N个通信装置，有助于节省第一信令的开销，减小N个通信装置的盲检量。而且一般来讲，在使用同样多的资源的情况下，传输的信息越少，则传输可靠性越高。那么，由于无需在第一信令中携带额外的信息指示N个通信装置，相当于用同样多的资源传输了较少的信息，由此可以提升第一信令的传输可靠性。
或者，第一信令指示N个通信装置，也可以显式指示。例如一种显式指示的方式为，第一信令包括一个通信装置的标识，就表明指示了该通信装置。那么例如第一信令包括N个通信装置的标识，就表明指示了N个通信装置。本申请实施例所述的一个通信装置的标识，例如为该通信装置的身份号(ID)，或者也可以是该通信装置在第一通信域中的地址，或者也可以是该通信装置所属的通信装置组的标识等，其中，一个通信装置组对应一个标识，一个通信装置组可以包括一个或多个通信装置。如果第一信令通过隐式方式指示一个 通信装置，那么对于第一通信域内的一个通信装置来说，如果检测第一信令失败，则该通信装置很可能无法区别检测失败是因为该通信装置未被调度，还是因为检测过程导致的检测失败，则可能导致该通信装置无法确定是否要继续检测后续的第二信令。而显式指示的方式就可以避免这种问题，各个通信装置都可以盲检第一信令，如果第一信令包括一个通信装置的标识，该通信装置就可以明确自身被调度，而如果第一信令不包括一个通信装置的标识，该通信装置就可以明确自身未被调度，使得通信装置后续的处理逻辑更为清晰。
当然第一信令还可以通过其他的显式指示方式指示N个通信装置，如上只是举例，并不是对显式指示方式的限制。
在前文介绍了，第一通信装置在发送第一信令后，可能会继续发送第二信令。那么，作为一种可选的实施方式，第一信令除了可以指示N个通信装置之外，还可以包括第二信令相应的信息。例如第一信令还可以包括如下的一项或多项：第二信令的MCS，第二信令的类型信息，第二信令的优先级信息，或，第二信令的数据量信息。例如，第一信令包括第二信令的MCS；或者，第一信令包括第二信令的MCS和第二信令的类型信息；或者，第一信令包括第二信令的MCS和第二信令的数据量信息；或者，第一信令包括第二信令的优先级信息和第二信令的数据量信息；或者，第一信令包括第二信令的MCS，第二信令的类型信息，以及第二信令的数据量信息；或者，第一信令包括第二信令的MCS，第二信令的优先级信息，以及第二信令的数据量信息等等。
第二信令的MCS是第二信令的调制编码方式，可包括第二信令的调制方式，或包括第二信令的编码方式，或包括第二信令的调制方式和编码方式。其中，第二信令的编码方式可包括第二信令的编码类型(例如低密度奇偶校验(low-density parity-check，LDPC)码或卷积码)和/或第二信令的码率等。第一信令如果包括第二信令的MCS，则N个通信装置根据该MCS接收第二信令即可，无需使用多种MCS盲检第二信令，减少N个通信装置的盲检量。或者，第一信令也可以不包括第二信令的MCS，例如第二信令的MCS可以是预设MCS，所述的预设MCS可以是通过协议规定的，或者是由第一通信装置预先设置并告知N个通信装置，或者也可以预配置在N个通信装置和第一通信装置中。如果是这种情况，那么第一信令无需包括第二信令的MCS，可以减小第一信令的信息量。由于第二信令的MCS是N个通信装置已知的，因此N个通信装置也无需使用多种MCS盲检第二信令，也能减少N个通信装置的盲检量。或者，第一信令不包括第二信令的MCS，第二信令的MCS也不采用预设MCS，N个通信装置可使用多种可能的MCS盲检第二信令。即使是这种情况，由于发送第二信令的第二资源与发送第一信令的第一资源具有关联关系，N个通信装置无需在多个资源上盲检第二信令，这已经在很大程度上减少了N个通信装置的盲检量。
第二信令的类型，例如指示如下信息中的一种或多种：第二信令是何种类型的信令(例如调度信令、载波切换信令或用于指示上报信道信息的信令等)，第二信令的调度类型(例如半静态调度类型或动态调度类型)，或，第二信令的优先级。其中，如果第二信令的类型仅指示第二信令的优先级，那么第二信令的类型信息和第二信令的优先级信息可以认为是同种信息，在这种情况下，该信息可以称为第二信令的类型信息，也可以称为第二信令的优先级信息。另外在这种情况下，认为第一信令可以包括如下的一种或多种信息：第二信令的MCS，第二信令的类型信息(或，第二信令的优先级信息)，或，第二信令的数据量信息。通过第一信令指示了第二信令的类型，则N个通信装置在解析第二信令时无需通 过盲检的方式解析，而是可以直接解析，这减少了N个通信装置的盲检量。
或者，第一信令也可以不包括第二信令的类型信息，例如第二信令的类型信息可以包括在第二信令中。通过这种方式，可以减小第一信令的数据量，使得通信装置对于第一信令的盲检量进一步减小。
或者，第二信令的类型信息也通过第一信令和第二信令共同指示。例如，第一信令可以包括第一指示信息，第二信令可以包括第二指示信息，从而N个通信装置结合第一指示信息和第二指示信息可以确定第二信令的类型信息，根据第二信令的类型信息解析第二信令的包体即可，无需按照多种类型对包体进行盲检，节省N个通信装置的盲检量。
通过第一信令指示了第二信令的数据量，则N个通信装置在解析第二信令时也无需通过盲检的方式解析，而是可以直接解析，这也减少了N个通信装置的盲检量。或者，第一信令也可以不包括第二信令的数据量信息，例如第二信令的数据量信息可以包括在第二信令中。通过这种方式，可以减小第一信令的数据量，使得通信装置对于第一信令的盲检量进一步减小。
需要注意的是，通过MCS盲检第二信令，是指在接收第二信令时的盲检，通过类型信息或信息的大小盲检第二信令，是指在接收第二信令之后对第二信令进行解析时的盲检，这两种盲检是不同的。
第一信令可以通过广播方式发送，这样可以使得第一通信域内的各个通信装置能够尽快确定自身是否被调度。当然第一信令也可以通过单播等方式发送，本申请实施例并不限制第一信令的发送方式。
例如第一通信域内的至少一个通信装置接收了第一信令，至少一个通信装置中的每个通信装置都可以通过解析第一信令确定第一信令是否包括该通信装置的标识。如果一个通信装置确定第一信令包括该通信装置的标识，则该通信装置确定被调度，该通信装置可继续执行后续的S22等步骤；或者，如果一个通信装置确定第一信令不包括该通信装置的标识，则该通信装置确定未被调度，则该通信装置无需再执行后续的S22等步骤。在本申请实施例中，例如N个通信装置确定第一信令包括自身的标识，则N个通信装置中的每个通信装置可继续执行后续的S22等步骤。其中，如果N个通信装置是确定第一信令包括自身所在的通信装置组的标识，那么这N个通信装置可以属于同一个通信装置组，或者也可以属于多个通信装置组。但由于各个通信装置执行后续步骤的方式都是类似的，因此本申请实施例只以N个通信装置中的第二通信装置执行后续步骤为例。
通过这种方式可以减少部分通信装置需执行的步骤，减少通信装置的盲检量，简化通信装置的实现复杂度，进一步地也可以节省通信装置的功耗。而第一信令由于包括的信息量较小，各个通信装置盲检第一信令的盲检量也较小，解析第一信令所需的功率损耗也不大，因此也可以简化通信装置的实现复杂度。而且由于第一信令已经指示了相应的通信装置，第二信令无需再指示通信装置，可见，作为调度信令而言，第一信令和第二信令的信息量都是有所减少的，由此可以提高调度信令的传输可靠性。
考虑到第一通信域中可能有些通信装置是需要节能的通信装置，作为一种可选的实施方式，可以为这些需要节能的通信装置设置唤醒周期。如果第一通信域中有多个通信装置需要节能，那么为这多个通信装置所设置的唤醒周期的时长可以相同，也可以不同。例如第二通信装置需要节能，则可以为第二通信装置设置唤醒周期。可以由第一通信装置为第二通信装置设置唤醒周期，或者唤醒周期也可以通过协议规定，或者唤醒周期也可以预配 置在第二通信装置中。
如果第二通信装置设置有唤醒周期，那么第二通信装置可以在每个唤醒周期内唤醒，检测来自第一通信装置或其他通信装置的信令。而在唤醒周期之外，第二通信装置可以处于休眠状态，无需检测信令，节省第二通信装置的功耗。例如第一资源位于第二通信装置的一个唤醒周期内，则第二通信装置可以在该唤醒周期内检测第一资源，以接收第一信令。在接收第一信令后，如果第二通信装置确定被调度，则第二通信装置继续在第二资源进行检测，以及第二通信装置在检测到第二信令后还会继续检测第一数据。在此过程中，即使唤醒周期结束，第二通信装置也会保持工作状态，不进入休眠模式，以接收相应的信息。或者，在接收第一信令后，如果第二通信装置确定未被调度，那么在该唤醒周期结束后，第二通信装置会正常进入休眠模式，在下一个唤醒周期开始时再开始检测来自其他通信装置的信令。例如，第一组资源所包括的部分资源或全部资源可以是周期性的资源，例如第一资源是周期性的资源，第二通信装置的唤醒周期可以是第一资源的周期的整数倍，这样第二通信装置可以在唤醒周期内检测第一资源。
S22、在第二资源发送第二信令，S22可以由第一通信装置执行，第二通信装置在第二资源接收第二信令。因为第一信令指示了N个通信装置，因此N个通信装置都可以在第二资源接收第二信令，此处只以N个通信装置中的第二通信装置接收第二信令为例。
第二信令可用于调度N个通信装置发送或接收第一数据。
例如第一资源属于所述的第一组资源，第二资源属于所述的第二组资源，第一资源和第二资源是具有关联关系的一对资源。也就是说，第一通信装置如果在第一组资源里选择了第一资源发送第一信令，那么第一通信装置在发送与第一信令相关的第二信令时，就会在第二组资源里选择与第一资源具有关联关系的第二资源发送第二信令。第一信令与第二信令相关是指，第二信令调度第一数据，而第一信令是用于指示第二信令所调度的通信装置，即，第一信令指示由哪些通信装置发送或接收第一数据。
以N个通信装置中的第二通信装置为例。对于第二通信装置来说，第一资源和第二资源之间的关联关系是已知的，因此第二通信装置可以在第二资源接收第二信令，无需在多个资源上盲检第二信令，减少了第二通信装置的盲检量。例如，可以在第一通信域内的全部或部分通信装置中预配置第一组资源和第二组资源之间的关联关系，例如在第一通信装置和第二通信装置中均预配置了第一组资源和第二组资源之间的关联关系，或者，第一组资源和第二组资源之间的关联关系可以通过协议规定，那么第一通信装置和第二通信装置都可以获知第一组资源和第二组资源之间的关联关系，因为第一资源属于第一组资源，第二资源属于第二组资源，因此第一通信装置和第二通信装置自然可以获知第一资源和第二资源具有关联关系。
或者，第一组资源和第二组资源之间的关联关系可以由第一通信装置设置，第一通信装置设置后可以将第一组资源和第二组资源之间的关联关系发送给第一通信域内除了第一通信装置外的部分或全部通信装置，那么第二通信装置就可以接收来自第一通信装置的第一组资源和第二组资源之间的关联关系。例如第一通信装置可以通过广播方式发送第四信令，第四信令可以指示第一组资源和第二组资源之间的关联关系，则第一通信域内除了第一通信装置外的部分或全部通信装置可接收来自第一通信装置的第四信令，这样就可以获得第一资源和第二资源具有关联关系，第二通信装置可以是接收第四信令的其中一个通信装置。
或者，第一通信装置也可以向N个通信装置发送第一资源和第二资源之间的关联关系，即，第一通信装置可以不必一次性向各个通信装置发送两组资源之间的关联关系，由于第一通信装置当前要应用的是第一资源和第二资源，因此第一通信装置可以只将第一资源和第二资源之间的关联关系发送给N个通信装置。同理，例如第一通信装置发送第四信令，第四信令可以指示第一资源和第二资源之间的关联关系，第一通信装置发送第一信令的方式例如为组播(接收组为N个通信装置)，或者也可以通过单播方式分别发送给N个通信装置。N个通信装置接收第四信令后就可以获知第一资源和第二资源之间的关联关系。如果采用这种方式，那么第一通信装置可以在每次需要使用第一组资源和第二组资源之前都向相应的通信装置发送待使用的资源之间的关联关系。
作为一种可选的实施方式，第一数据对应于第一业务，例如第一数据也可称为第二数据。第一业务可以是动态业务，或者也可以是非动态业务。在本申请实施例中，可将除动态业务之外的其他业务统称为非动态业务，一种非动态业务例如为周期性业务，例如降噪业务等。如果第一业务是非动态业务，那么可以理解为，本申请实施例针对非动态业务，提供了两级调度的方式，第一信令作为第一级调度，第二信令作为第二级调度。第一级调度对应的调度信令(例如第一信令)只需指示相应的通信装置(例如第一信令指示N个通信装置)，无需指示过多内容，使得第一级调度对应的调度信令的信息量较小，即使第一通信域中的各个通信装置都要盲检第一级调度对应的调度信令，但因为信息量较小，因此盲检量也不会很大。第一级调度对应的调度信令占用的资源和第二级调度对应的调度信令占用的资源之间具有关联关系，被调度的节点在检测第二级调度对应的调度信令(例如第二信令)时，在相应的资源上检测即可，无需在过多的资源上盲检，由此也减少了被调度的节点的盲检量。
如果第一业务是非动态业务，那么第一业务的调度方式例如为半静态调度方式。第一数据对应于第一业务，则第一数据就可以使用半静态调度方式来调度。例如第二信令的类型信息还指示第二信令的调度类型，那么第二信令的调度类型可以是半静态调度类型。或者，虽然第一业务是非动态业务，但第一业务也可以不采用半静态调度方式而是采用其他调度方式来调度，或者，如果第一业务是动态业务，则第一业务同样可以不采用半静态调度方式而是采用其他调度方式来调度，那么第一数据就不使用半静态调度方式调度。本申请实施例对于第一数据的调度方式不做限制。
在两级调度过程中，由于第二信令需要调度第一数据，因此第二信令包括的内容可能较多，较为复杂。因此可选的，第二信令例如为高层信令，例如RRC信令或MAC CE等。高层信令的容量较大，可以包括较多的信息。或者，第二信令也可以是其他信令，例如物理层信令等，本申请实施例对此不做限制。
如果第二信令是高层信令，且第二信令包括第二信令的类型信息，则第二信令的类型信息可以包括在第二信令的包头中。第二通信装置通过解析第二信令的包头就可以获得第二信令的类型信息，从而第二通信装置根据第二信令的类型信息解析第二信令的包体即可，无需按照多种类型对包体进行盲检，节省第二通信装置的盲检量。
同理，如果第二信令是高层信令，且第二信令包括第二信令的数据量信息，则第二信令的数据量信息也可以包括在第二信令的包头中。第二通信装置通过解析第二信令的包头就可以获得第二信令的数据量信息，从而第二通信装置根据第二信令的数据量信息解析第二信令的包体即可，无需按照多种可能的数据量对包体进行盲检，节省第二通信装置的盲 检量。
另外，在前文也介绍了，第二信令的类型信息也可以通过第一信令和第二信令共同指示。那么如果第二信令是高层信令，则所述的第二指示信息可以包括在第二信令的包头内，从而第二通信装置结合第一指示信息和第二指示信息可以确定第二信令的类型信息，根据第二信令的类型信息解析第二信令的包体即可，无需按照多种类型对包体进行盲检，节省第二通信装置的盲检量。
第二信令可以调度第一数据，例如第二信令可以包括如下的一项或多项：用于发送或接收第一数据的资源信息(包括时域资源信息，或频域资源信息，或时域资源信息和频域资源信息)，第一数据的MCS，第一数据的类型信息，或，用于发送第一数据的功率控制信息。例如，第二信令包括用于发送第一数据的资源；或者，第二信令包括用于发送第一数据的资源和第一数据的MCS；或者，第二信令包括用于发送第一数据的资源，第一数据的MCS，以及第一数据的类型信息；或者，第二信令包括用于发送第一数据的资源，第一数据的MCS，第一数据的类型信息，以及用于发送第一数据的功率控制信息，等等。其中，用于发送或接收第一数据的时域资源信息，可以指示用于发送或接收第一数据的资源的时域位置，用于发送或接收第一数据的频域资源信息，可以指示用于发送或接收第一数据的资源的频域位置。另外，用于发送第一数据的资源，不属于如前所述的第一组资源，也不属于所述的第二组资源。
第一数据的编码方式可包括第一数据的编码类型(例如LDPC码或卷积码)和/或度数据的码率等。第一数据的类型信息例如指示第一数据为数据类型的信息。
如果第二信令是调度N个通信装置接收来自第一通信装置的第一数据，那么第一通信装置在发送第二信令后，还可以按照第二信令向N个通信装置发送第一数据，N个通信装置可根据第二信令接收来自第一通信装置的第一数据。或者，如果第二信令是调度N个通信装置向第一通信装置发送第一数据，那么N个通信装置在接收第二信令后，还可以按照第二信令向第一通信装置发送第一数据，第一通信装置可根据第二信令接收来自N个通信装置中的每个通信装置的第一数据。
可选的，N个通信装置接收第二信令后，N个通信装置中的部分通信装置或全部通信装置中的每个通信装置可以向第一通信装置发送反馈信息，例如称为第二反馈信息，则第一通信装置可以接收来自N个通信装置中的部分通信装置或全部通信装置中的每个通信装置的第二反馈信息，第二反馈信息可以指示第二信令接收成功或接收失败。例如第二通信装置向第一通信装置发送了第二反馈信息，则第一通信装置可接收来自第二通信装置的第二反馈信息。例如第二反馈信息为物理层的反馈，例如为肯定应答(ACK)或否定应答(NACK)，或者第二反馈信息也可以是高层的反馈，对于反馈信息的类型不做限制。
可选的，如果第二信令用于调度N个通信装置接收第一数据，N个通信装置中的部分通信装置或全部通信装置中的每个通信装置接收第一数据后也可以向第一通信装置发送反馈信息，例如称为第三反馈信息，则第一通信装置可以接收来自N个通信装置中的部分通信装置或全部通信装置中的每个通信装置的第三反馈信息，第三反馈信息可以指示第一数据接收成功或接收失败。例如第二通信装置向第一通信装置发送了第三反馈信息，则第一通信装置可接收来自第二通信装置的第三反馈信息。或者，如果第二信令用于调度N个通信装置发送第一数据，第一通信装置接收第一数据后也可以向N个通信装置中的部分通信装置或全部通信装置中的每个通信装置发送反馈信息，例如称为第四反馈信息，则N个 通信装置中的部分通信装置或全部通信装置中的每个通信装置可接收来自第一通信装置的第四反馈信息，例如第一通信装置向第二通信装置发送了第四反馈信息，则第二通信装置可接收来自第一通信装置的第四反馈信息。第四反馈信息可以指示第一数据接收成功或接收失败。例如第三反馈信息或第四反馈信息也可以为物理层的反馈，例如为ACK或NACK，或者第三反馈信息或第四反馈信息也可以是高层的反馈，对于反馈信息的类型不做限制。
S23、在第三资源发送第三信令，S23可以由第一通信装置执行，第一通信装置所在的通信域中的至少一个通信装置在第三资源接收来自第一通信装置的第三信令，这至少一个通信装置包括第二通信装置，图2以第二通信装置接收第三信令为例。第三信令可以指示M个通信装置，这M个通信装置可以是第一通信域内除第一通信装置外的全部或部分通信装置，M为大于或等于1的整数。
第三信令所指示的M个通信装置与第一信令指示的N个通信装置可以是相同的通信装置；或者，M个通信装置包括N个通信装置中的全部或部分，还包括除N个通信装置外的其他通信装置；或者，N个通信装置包括M个通信装置中的全部或部分，还包括除M个通信装置外的其他通信装置；或者，M个通信装置与N个通信装置没有交集，即，M个通信装置与N个通信装置不同。在本申请实施例中，以第一信令和第三信令均指示了第二通信装置为例，因此是以M个通信装置与N个通信装置有交集为例。
第三资源可以属于第一组资源，那么在第二组资源内存在与第三资源具有关联关系的资源，例如第四资源。第一通信装置发送第三信令的目的，例如是为了在第四资源发送第一信号，或者说是为了调度M个通信装置在第四资源接收第一信号。第一信号可包括如下的一种或多种：第二数据，第一高层信令，或参考信号。例如，第一信号包括第二数据；或者，第一信号包括第一高层信令；或者，第一信号包括参考信号；或者，第一信号包括第二数据和参考信号，等等。第二数据例如对应于第二业务，那么也可以将第二数据称为第二业务数据。第二业务可以是动态业务，或者也可以是非动态业务。第一业务与第二业务可以是同种业务，例如第一业务和第二业务均为动态业务，或者第一业务和第二业务也可以是不同的业务，例如第一业务为非动态业务，第二业务为动态业务。第一高层信令例如为RRC信令或MAC CE等。参考信号可实现如下的一种或多种功能：时间同步，频率同步，相位跟踪，信道质量探测，信道估计，或，干扰测量。例如，参考信号可实现时间同步功能；或者，参考信号可实现频率同步功能；或者，参考信号可实现相位跟踪功能；或者，参考信号可实现信道质量探测功能；或者，参考信号可实现信道估计功能；或者，参考信号可实现干扰测量功能；或者，参考信号可实现信道质量探测功能和信道估计功能，等等。
例如第二业务为动态业务。对于动态业务、高层信令或参考信号等，可能发生较为随机，周期性不强，如果采用如前所述的两级调度模式，可能会导致调度信令的数量较多。为此，本申请实施例针对动态业务、高层信令或参考信号等，可采用一级调度模式，第三信令可以作为调度信令，第一通信装置在发送调度信令后就可以发送该调度信令所调度的动态业务、第一高层信令或参考信号。一级调度的方式有助于减少调度信令的数量，节省信令开销。调度信令(例如第三信令)只需指示相应的通信装置(例如第三信令指示M个通信装置)，无需指示过多内容，使得调度信令的信息量较小，即使第一通信域中的各个通信装置都要盲检调度信令，但因为信息量较小，因此盲检量也不会很大。调度信令占用 的资源(例如第三资源)和所调度的信息(例如第一信号)占用的资源(例如第四资源)之间具有关联关系，被调度的通信装置在检测所调度的信息(例如第一信号)时，在相应的资源上检测即可，无需在过多的资源上盲检，由此也减少了被调度的通信装置的盲检量。
例如，第一数据仅为非动态业务，且仅使用半静态调度方式来调度；对于动态业务(例如第二业务)，则使用所述的一级调度模式来调度。这样可以减少第二信令的类型，简化调度信令(例如第二信令)。并且，由于可用于传输第一数据的资源仅使用半静态调度方式调度，也可以避免可用于传输第一数据的资源碎片化。
在调度动态业务、高层信令或参考信号时，虽然是使用一级调度模式，但调度过程类似于两级调度的过程，例如也可以从第一组资源中选择资源来发送调度信令，以及从第二组资源中选择相应的资源发送第一信号，使得一级调度过程和两级调度过程统一，简化了整体的数据调度流程。另外，动态业务、高层信令或参考信号可以与第二级调度信令复用资源(这里是指，都可以使用第二组资源)，由此也提高了资源的利用率。
第三信令例如为物理层信令，例如DCI，或者也可以是其他的物理层信令。第三信令的作用是让相应的通信装置知晓该通信装置被调度，例如第三信令指示M个通信装置，就表明这M个通信装置被调度。物理层信令的处理流程短，因此处理速度快，因此如果第三信令为物理层信令，则相应的通信装置可以快速确定自身是否被调度。或者第三信令也可以是其他信令，例如高层信令等，本申请实施例不做限制。
第三信令指示M个通信装置，可以隐式指示，也可以显式指示。关于第三信令指示M个通信装置的方式，可参考S21中对于第一信令指示M个通信装置的方式的介绍。
作为一种可选的实施方式，第三信令除了可以指示M个通信装置之外，还可以包括第一信号相应的信息。例如第三信令还可以包括如下的一项或多项：第一信号的MCS，第一信号的类型信息，第一信号的优先级信息，或，第一信号的数据量信息。例如，第三信令包括第一信号的MCS；或者，第三信令包括第一信号的MCS和第一信号的类型信息；或者，第三信令包括第一信号的MCS和第一信号的数据量信息；或者，第三信令包括第一信号的优先级信息和第一信号的数据量信息；或者，第三信令包括第一信号的MCS，第一信号的类型信息，以及第一信号的数据量信息；或者，第三信令包括第一信号的MCS，第一信号的优先级信息，以及第一信号的数据量信息等等。
第一信号的MCS是第一信号的调制编码方式，可包括第一信号的调制方式，或包括第一信号的编码方式，或包括第一信号的调制方式和编码方式。其中，第一信号的编码方式可包括第一信号的编码类型(例如LDPC码或卷积码)和/或第一信号的码率等。第三信令如果包括第一信号的MCS，则M个通信装置根据该MCS接收第一信号即可，无需使用多种MCS盲检第一信号，减少M个通信装置的盲检量。或者，第三信令也可以不包括第一信号的MCS，例如第一信号的MCS可以是预设MCS，所述的预设MCS可以是通过协议规定的，或者是由第一通信装置预先设置并告知M个通信装置，或者也可以预配置在M个通信装置和第一通信装置中。如果是这种情况，那么第三信令无需包括第一信号的MCS，可以减小第三信令的信息量。由于第一信号的MCS是M个通信装置已知的，因此M个通信装置也无需使用多种MCS盲检第一信号，也能减少M个通信装置的盲检量。或者，第三信令不包括第一信号的MCS，第一信号的MCS也不采用预设MCS，M个通信装置可使用多种可能的MCS盲检第一信号。即使是这种情况，由于发送第三信令的第三资源与发送第一信号的第四资源具有关联关系，M个通信装置无需在多个资源上盲检第一信号， 这已经在很大程度上减少了M个通信装置的盲检量。
第一信号的类型，例如指示如下信息中的一种或多种：第一信号是信令、数据或信号，如果第一信号为信令，则还可以指示具体是何种类型的信令(例如调度信令、载波切换信令或用于指示上报信道信息的信令等)，第一信号的调度类型(例如半静态调度类型或动态调度类型)，或，第一信号的优先级。其中，如果第一信号的类型仅指示第一信号的优先级，那么第一信号的类型信息和第一信号的优先级信息可以认为是同种信息，在这种情况下，该信息可以称为第一信号的类型信息，也可以称为第一信号的优先级信息。另外在这种情况下，认为第三信令可以包括如下的一种或多种信息：第一信号的MCS，第一信号的类型信息(或，第一信号的优先级信息)，或，第一信号的数据量信息。通过第三信令指示了第一信号的类型，则M个通信装置在解析第一信号时无需通过盲检的方式解析，而是可以直接解析，这减少了M个通信装置的盲检量。
或者，第三信令也可以不包括第一信号的类型信息，例如第一信号的类型信息可以包括在第一信号中。通过这种方式，可以减小第三信令的数据量，使得通信装置对于第三信令的盲检量进一步减小。
或者，第一信号的类型信息也通过第三信令和第一信号共同指示。例如，第三信令可以包括第三指示信息，第一信号可以包括第四指示信息，从而M个通信装置结合第三指示信息和第四指示信息可以确定第一信号的类型信息，根据第一信号的类型信息解析第一信号的包体即可，无需按照多种类型对包体进行盲检，节省M个通信装置的盲检量。
通过第三信令指示了第一信号的数据量，则M个通信装置在解析第一信号时也无需通过盲检的方式解析，而是可以直接解析，这也减少了M个通信装置的盲检量。或者，第三信令也可以不包括第一信号的数据量信息，例如第一信号的数据量信息可以包括在第一信号中。通过这种方式，可以减小第三信令的数据量，使得通信装置对于第三信令的盲检量进一步减小。
需要注意的是，通过MCS盲检第一信号，是指在接收第一信号时的盲检，通过类型信息或信息的大小盲检第一信号，是指在接收第一信号之后对第一信号进行解析时的盲检，这两种盲检是不同的。
第三信令可以通过广播方式发送，这样可以使得第一通信域内的各个通信装置能够尽快确定自身是否被调度。当然第三信令也可以通过单播等方式发送，本申请实施例并不限制第三信令的发送方式。
例如第一通信域内的至少一个通信装置接收了第三信令，至少一个通信装置中的每个通信装置都可以通过解析第三信令确定第三信令是否包括自身的标识。如果一个通信装置确定第三信令包括该通信装置的标识，则该通信装置确定被调度，该通信装置可继续执行后续的S24等步骤；或者，如果一个通信装置确定第三信令不包括该通信装置的标识，则该通信装置确定未被调度，则该通信装置无需再执行后续的S24等步骤。在本申请实施例中，例如M个通信装置确定第三信令包括自身的标识，则M个通信装置中的每个通信装置可继续执行后续的S24等步骤。但由于各个通信装置执行后续步骤的方式都是类似的，因此本申请实施例只以M个通信装置中的第二通信装置执行后续步骤为例。
通过这种方式可以减少部分通信装置需执行的步骤，简化通信装置的实现复杂度，进一步也可以节省通信装置的功耗。而第三信令由于包括的信息量较小，各个通信装置盲检第三信令的盲检量也较小，解析第三信令所需的功率损耗也不大，因此也可以节省通信装 置的功耗。
如果按照S21中的介绍，第二通信装置设置有唤醒周期，那么例如第三资源位于第二通信装置的一个唤醒周期内，则第二通信装置可以在该唤醒周期内检测第三资源，以接收第三信令。在接收第三信令后，如果第二通信装置确定被调度，则第二通信装置继续在第四资源检测第一信号。在此过程中，即使第四资源位于第二通信装置的唤醒周期之外，那么在唤醒周期结束时，第二通信装置会继续保持工作状态，不进入休眠模式，以检测第四资源。或者，在接收第三信令后，如果第二通信装置确定未被调度，那么在该唤醒周期结束后，第二通信装置会正常进入休眠模式，在下一个唤醒周期开始时再开始检测来自其他通信装置的信令。
S24、在第四资源发送第一信号，S24可以由第一通信装置执行，第二通信装置在第四资源接收第一信号。因为第三信令指示了M个通信装置，因此M个通信装置都可以在第四资源接收第一信号，此处只以M个通信装置中的第二通信装置接收第一信号为例。
例如第三资源属于所述的第一组资源，第四资源属于所述的第二组资源，第三资源和第四资源是具有关联关系的一对资源。也就是说，第一通信装置如果在第一组资源里选择了第三资源发送第三信令，那么第一通信装置在发送与第三信令相关的第一信号时，就会在第二组资源里选择与第三资源具有关联关系的第四资源发送第一信号。第三信令与第一信号相关是指，第三信令调度第一信号。
以M个通信装置中的第二通信装置为例。对于第二通信装置来说，第三资源和第四资源之间的关联关系是已知的，因此第二通信装置可以在第四资源接收第一信号，无需在多个资源上盲检第一信号，减少了第二通信装置的盲检量。关于第二通信装置获知第三资源和第四资源之间的关联关系的方式，可参考S22中对于第二通信装置获知第一资源和第二资源之间的关联关系的方式的介绍。
如果第一信号包括第一信号的类型信息，则第一信号的类型信息可以包括在第一信号的包头中。第二通信装置通过解析第一信号的包头就可以获得第一信号的类型信息，从而第二通信装置根据第一信号的类型信息解析第一信号的包体即可，无需按照多种类型对包体进行盲检，节省第二通信装置的盲检量。
同理，如果第二信令是高层信令，且第一信号包括第一信号的数据量信息，则第一信号的数据量信息也可以包括在第一信号的包头中。第二通信装置通过解析第一信号的包头就可以获得第一信号的数据量信息，从而第二通信装置根据第一信号的数据量信息解析第一信号的包体即可，无需按照多种可能的数据量对包体进行盲检，节省第二通信装置的盲检量。
另外，在前文也介绍了，第一信号的类型信息也可以通过第三信令和第一信号共同指示。例如，所述的第四指示信息可以包括在第一信号的包头内，从而第二通信装置结合第三指示信息和第四指示信息可以确定第一信号的类型信息，根据第一信号的类型信息解析第一信号的包体即可，无需按照多种类型对包体进行盲检，节省第二通信装置的盲检量。
其中，S21～S22可以发生在S23～S24之前，或者，S21～S22可以发生在S23～S24之后，或者，S21～S22与S23～S24可以同时发生。另外，S23～S24是可选的步骤，在图2中用虚线表示。
可选的，N个通信装置中的部分通信装置或全部通信装置中的每个通信装置接收第一信号后可以向第一通信装置发送反馈信息，例如称为第一反馈信息，则第一通信装置可以 接收来自N个通信装置中的部分通信装置或全部通信装置中的每个通信装置的第一反馈信息，第一反馈信息可以指示第一信号接收成功或接收失败。例如第二通信装置向第一通信装置发送了第一反馈信息，则第一通信装置可以接收来自第二通信装置的第一反馈信息。例如第一反馈信息为物理层的反馈，例如为ACK或NACK，或者第一反馈信息也可以是高层的反馈，对于反馈信息的类型不做限制。
例如可参考图3，为本申请实施例提供的两级调度过程和一级调度过程的示例。例如两级调度过程为，第一通信装置在第一组资源包括的第一资源发送第一信令，那么第一通信装置会在第二组资源包括的与第一资源具有关联关系的第二资源发送第二信令，第二信令可以调度第一数据。例如一级调度过程为，第一通信装置在第一组资源包括的第三资源发送第三信令，那么第一通信装置会在第二组资源包括的与第三资源具有关联关系的第四资源发送第一信号。
S25、在第五资源发送第五信令，S25可以由第一通信装置执行，第一通信装置所在的通信域中的至少一个通信装置在第五资源接收来自第一通信装置的第五信令，这至少一个通信装置包括第二通信装置，图2以第二通信装置接收第五信令为例。第五信令可以指示不调度任意通信装置在第六资源接收信号，或者说，第五信令指示不调度任何通信装置在第六资源接收信号，即，第一通信域内没有通信装置会被第五信令所调度。
第五资源可以属于第一组资源，那么在第二组资源内存在与第五资源具有关联关系的资源，例如第六资源。如果第五信令调度相应的通信装置接收信号，则被调度的通信装置可以在第六资源接收信号。但第五信令是不调度任意通信装置在第六资源接收信号，那么第一通信域内接收了第五信令的通信装置都可以不必检测第六资源。在这种情况下，第六资源未被调度，那么可选的，第一通信域内接收了第五信令的一个或多个通信装置可以利用第六资源来进行干扰侦听等操作。
第五信令用于指示不调度任意通信装置在第六资源接收信号，可以有多种实现方式。例如一种实现方式为，第五信令包括第一标识，第一标识不用于指示任意通信装置或通信装置组(可理解为多个通信装置)，或者理解为，第一标识不是任何一个通信装置或通信装置组的标识。第一标识例如为通信装置的标识，例如通信装置的ID。但第一标识可以是缺省(default)标识，或者说第一标识为保留标识，对此可理解为，第一标识所指示的通信装置并不存在，或者至少在第一通信域中不存在。或者，第一标识例如为通信装置组的标识，例如通信装置组的ID。但第一标识可以是缺省标识，或者说第一标识为保留标识，对此可理解为，第一标识所指示的通信装置组并不存在，或者至少在第一通信域中不存在。那么对于接收了第五信令的一个通信装置来说，可以确定第五信令不调度任何通信装置或通信装置组在第六资源接收信号，或者，可以确定第五信令不调度该通信装置在第六资源接收信号。
又例如，另一种实现方式为，第五信令不包括通信装置的标识。那么对于接收了第五信令的一个通信装置来说，因为第五信令不包括通信装置的标识，则可以确定第五信令不调度任何通信装置在第六资源接收信号，或者，可以确定第五信令不调度该通信装置在第六资源接收信号。
其中，一个通信装置接收第五信令后，所确定的是第五信令不调度任何通信装置接收信号，或者，可以确定第五信令不调度该通信装置接收信号，而该通信装置可以确定第五资源与第六资源具有关联关系，因此也可以认为该通信装置确定的是第五信令不调度任何 通信装置在第六资源接收信号，或者确定的是第五信令不调度该通信装置在第六资源接收信号。
可选的，还可以设置第三组资源，第三组资源与第一组资源也可以具有对应关系。关于第一组资源与第三组资源的对应方式，可参考前文对于第一组资源与第二组资源的对应方式的介绍。那么，第五信令可以指示不调度任意通信装置在第六资源接收信号，或者，也可以指示不调度任意通信装置在第七资源发送信号(或者说，第五信令指示不调度任何通信装置在第七资源发送信号，即，第一通信域内没有通信装置会被第五信令所调度)。第五资源属于第一组资源，那么在第三组资源内存在与第五资源具有关联关系的资源，例如第七资源。如果第五信令调度相应的通信装置发送信号，则被调度的通信装置可以在第七资源发送信号。但第五信令是不调度任意通信装置在第七资源发送信号，那么第一通信域内接收了第五信令的通信装置都可以不必使用第七资源发送信号。在这种情况下，相当于第七资源未被调度，那么可选的，第一通信域内接收了第五信令的一个或多个通信装置可以利用第七资源来进行干扰侦听等操作。
第五信令用于指示不调度任意通信装置在第七资源发送信号，具体的指示方式可参考对于第五信令不调度任意通信装置在第六资源接收信号的指示方式的介绍。
第五信令可以通过广播方式发送，以使得第一通信域内的各个通信装置都能接收第五信令。例如第五信令为物理层信令，或者也可以是高层信令等。第五信令可以周期性发送，或者也可以非周期性发送。
S26、不在与第五资源具有关联关系的第六资源进行检测。S26可以由接收了第五信令的全部通信装置或部分通信装置中的每个通信装置执行，但每个通信装置执行S26的方式都可以是类似的。例如第二通信装置接收了第五信令，因此以S26由第二通信装置执行为例。
如果一个通信装置接收了第五信令，可以确定自身未被调度，那么该通信装置就不必检测第六资源。其中，S21～S22可以发生在S25～S26之前，或者，S21～S22可以发生在S25～S26之后，或者，S21～S22与S25～S26可以同时发生。另外，S25～S26是可选的步骤，在图2中用虚线表示。
如果一个通信装置接收了第五信令，可以确定自身还处于第一通信域的范围内，从这个意义上来讲，第五信令可以视为一种心跳信息，可以使得通信装置明确是否移动出了一个通信域的范围，从而通信装置可以采取相应的应对策略。例如对于图1A所示的网络架构来说，手机可作为通信域2的一个从节点，手机由用户持有，可能会发生移动。例如通信域2内的主节点CDC会周期性发送第五信令，如果手机在某个周期或某几个周期内未检测到第五信令，手机就可以确定已移动出了通信域2的范围，则手机可以重新与通信域2建立连接，或者选择与其他通信域建立连接等。
综上，在本申请实施例中，可以实现两级调度方式，第一信令只需指示相应的通信装置，无需包括过多的信息，使得第一信令的信息量较小。各通信装置在盲检时，由于第一信令的信息量较小，因此盲检量也比较小。而每个通信装置在检测到第一信令后就可以确定该通信装置是否被调度，从而未被调度的通信装置不必再检测第二信令，可减少这些通信装置的无效盲检。另外，第一资源与第二资源具有关联关系，那么第二通信装置在确定第一资源后就可以确定第二资源，从而在第二资源上检测第二信令即可，无需在过多的资源上盲检，由此可以进一步节省通信装置的盲检量，简化通信装置的实现复杂度，进一步 也可以减小通信装置的功耗。另外，即使是一级调度模式，也可以复用两级调度模式的资源，从而提高资源的利用率。

本申请实施例还提供一种通信装置，该通信装置可以是终端设备也可以是电路，或者也可以是车载模块。该通信装置可以用于执行上述方法实施例中由第一通信装置或第二通信装置所执行的动作。
