Description

通信方法和通信设备 技术领域
本申请实施例涉及通信领域，尤其涉及通信方法和通信设备。
背景技术
为了应对未来移动数据流量增长、海量移动通信的设备连接、不断涌现的各类新业务和应用场景，第五代(the fifth generation，5G)移动通信系统应运而生。5G以及未来的移动通信系统中定义了三大类应用场景：增强型移动宽带(enhanced mobile broadband，eMBB)、高可靠低时延通信(ultra reliable and low latency communications，URLLC)以及海量机器类通信(massive machine type communications，mMTC)。
典型的eMBB业务有：超高清视频、增强现实(augmented reality，AR)、虚拟现实(virtual reality，VR)等，这些业务的主要特点是传输数据量大、传输速率很高。典型的URLLC业务有：工业制造或生产流程中的无线控制、无人驾驶汽车和无人驾驶飞机的运动控制以及远程修理、远程手术等触觉交互类应用，这些业务的主要特点是要求超高可靠性、低延时，传输数据量较少以及具有突发性。典型的mMTC业务有：智能电网配电自动化、智慧城市等，主要特点是联网设备数量巨大、传输数据量较小、数据对传输时延不敏感，这些mMTC终端需要满足低成本和非常长的待机时间的需求。
目前，可使用下行控制信息(downlink control information，DCI)指示不同类型的业务所需的资源，而不同类型的业务对移动通信系统的资源需求不同，这就会极大增加DCI的指示开销。如何减少DCI的指示开销，还没有提供相应的解决方案。
发明内容
本申请实施例提供了通信方法和通信设备，用于减少指示信息的开销。
为解决上述技术问题，本申请实施例提供以下技术方案：
第一方面，本申请实施例提供一种通信方法，包括：在第一资源上接收来自第二通信设备的第一信息，所述第一资源以及所述第一信息指示用于第二信息传输的第二资源；在所述第二资源上接收所述第二信息；或，在所述第二资源上发送所述第二信息。在该方案中，第二通信设备在第一资源上向第一通信设备发送第一信息，第一通信设备在第一资源上可接收到该第一信息，第一资源以及第一信息指示用于第二信息传输的第二资源，即第一资源与第一信息共同用于指示该第二资源，因此针对第二资源的指示不仅仅依赖于第一信息，还可以使用传输第一信息的第一资源，从而减少了第一信息指示第二资源时的指示开销。
在一种可能的实现方式中，所述第一资源以及所述第一信息指示用于第二信息传输的第二资源，包括：所述第一信息指示所述第二资源的资源长度；和/或，所述第一资源用于确定所述第二资源的起始资源。在该方案中，第一资源指示第二资源的起始资源，第一信息指示第二资源的资源长度，因此本申请实施例中第二资源可以通过第一资源结合第一信息的方式进行指示，因此针对第二资源的指示不仅仅依赖于第一信息，相比于通过第一信 息本身从而减少了第一信息指示第二资源时的指示开销。
在一种可能的实现方式中，所述第一资源的起始资源或结束资源，与所述第二资源的起始资源之间满足预设的关系。在该方案中，第一资源的起始资源或结束资源，与第二资源的起始资源之间满足预设的关系。该预设的关系可以根据具体场景灵活设置，例如在通信协议中预先定义该预设的关系，或者该预设的关系由第二通信设备通知给第一通信设备。在确定出第一资源的起始资源或结束资源之后，根据该第一资源的起始资源或结束资源确定第二资源的起始资源，即第一资源和第二资源的起始资源之间满足预设的特定关系，从而第一通信设备在确定出第一资源时，就可以基于该第一资源确定出第二资源的起始资源。
在一种可能的实现方式中，所述第一信息中的P个比特指示所述第二资源的资源长度；所述P的取值是预先定义的；或，所述P的取值为log 2N，所述N是根据所述第一通信设备的带宽、所述第一资源或所述第二资源所在的载波宽度、所述第一资源或所述第二资源所在的带宽分段BWP大小、所述第一资源或所述第二资源所在的控制资源集coreset的大小、所述第一资源或所述第二资源所在的搜索空间的资源大小、子载波间隔、资源单元的大小、所述第二资源所在的频率范围中的一种或多种确定，其中，所述资源单元包括一个或多个的资源块。在该方案中，预先规定该P的取值大小，例如预先规定P为5，或者6或者其它数值等，例如第一信息中存在5个比特的字段用于指示第二资源的资源长度，无论所指示的第二资源的资源长度为多少，第一信息中都只使用5个比特的字段指示第二资源的资源长度，保证不同带宽下第二资源指示需要的比特数相同，有利于第一信息的格式统一，简化通信双方的处理复杂度。另外，第一通信设备和第二通信设备都可以通过N的取值确定P的取值，例如P等于log 2N，从而第一通信设备和第二通信设备可以确定第一信息中存在log 2N个比特的字段用于指示第二资源的资源长度。
在一种可能的实现方式中，所述第二资源的起始资源是所述第一资源中的第1个资源单元；或，所述第二资源的起始资源是所述第一资源中的第i+1个资源单元，所述i的值包括如下至少一种：M/4、M/2、3M/4、M，其中，所述M是所述第一资源包含的资源单元个数；或，所述第二资源的起始资源是所述第一资源中的预先规定的资源单元。在该方案中，在该方案中，第二资源的起始资源是第一资源中的第1个资源单元，从而第一通信设备可以在确定第一资源之后，根据第一资源的第1个资源单元确定出第二资源的起始资源，不需要在第一信息来指示第二资源的起始资源，从而节省第一信息的指示开销。第二资源的起始资源是第一资源中的第i+1个资源单元，从而第一通信设备可以在确定第一资源之后，根据第一资源的第i+1个资源单元确定出第二资源的起始资源，不需要在第一信息来指示第二资源的起始资源，从而节省第一信息的指示开销。第二资源的起始资源是第一资源中的预先规定的资源单元，从而第一通信设备可以在确定第一资源之后，根据预先规定确定出第二资源的起始资源，不需要在第一信息来指示第二资源的起始资源，从而节省第一信息的指示开销。
在一种可能的实现方式中，所述资源单元的大小根据所述第一通信设备的带宽、所述第一资源或所述第二资源所在的BWP大小、所述第一资源的资源大小、所述第二信息对应的子载波间隔中的一种或多种确定。在该方案中，资源单元表示的是资源的调度粒度，一个资源单元具体包括一个或多个的资源块，资源单元的大小可以有多种，例如该资源单元 可以根据第一通信设备的带宽确定，或者资源单元根据第一资源或第二资源所在的BWP大小确定，或者资源单元根据第一资源的资源大小确定，或者资源单元根据第二信息对应的子载波间隔确定。或者资源单元根据带宽、BWP大小、资源大小、子载波间隔共同确定。这样，资源单元的大小是灵活可配置的，因此就可以保证不同子载波间隔、不同带宽情况下需要的资源指示信息的比特数保持不变。
在一种可能的实现方式中，所述第一信息还指示用于第三信息传输的第三资源，其中，所述第三信息是所述第二通信设备发送给第三通信设备的信息，或，所述第三信息是所述第二通信设备接收来自第三通信设备的信息；所述第三通信设备的带宽大于所述第一通信设备的带宽，其中，所述带宽包括如下至少一种：下行带宽、上行带宽、系统最大带宽、支持的最大带宽。在该方案中，第一信息可以同时用于指示第二资源，以及指示第三资源，因此第二通信设备可以通过一条第一信息实现针对第一通信设备和第三通信设备各自所需资源的指示，提高了向各种类型的终端设备指示资源的效率，且所使用的第一信息所需要的指示开销很小。
在一种可能的实现方式中，所述第一信息还包括第一字段，所述第一字段包括3个比特，所述第一字段指示用于所述第二信息传输的调制编码方式MCS；和/或，所述第一信息还包括第二字段，所述第二字段包括5个比特，所述第二字段指示用于第三信息传输的MCS，所述第三信息是第三通信设备发送或者接收的信息。在该方案中，第一信息还可以用于MCS的指示，例如第一信息中使用第一字段指示用于第二信息传输的MCS，该第一字段可以是第一信息中的保留字段。又如，第一信息使用第二字段指示用于第三信息传输的MCS，该第二字段可以是第一信息中的调制编码方式指示字段。本申请实施例第一信息可以通过第一字段/或第二字段实现对不同类型终端传输信息所用的MCS的指示。
在一种可能的实现方式中，所述第一信息还包括第三字段，所述第三字段指示用于所述第二信息传输的MCS和所述第二资源。在该方案中，第一信息中只需要通过第三字段就可以实现指示MCS和指示第二资源的联合编码，进一步节省了第一信息的比特数开销。
在一种可能的实现方式中，所述第一信息还包括第四字段，所述第四字段包括2或3个比特，所述第四字段指示传输所述第二信息的时域资源配置；和/或，所述第一信息还包括第五字段，所述第五字段包括4个比特，所述第五字段指示传输第三信息的时域资源配置，所述第三信息是第三通信设备发送或者接收的信息。在该方案中，第一信息还可以用于时域资源配置的指示，例如第一信息中使用第四字段指示用于第二信息传输的时域资源配置，该第四字段可以是第一信息中的保留字段。又如，第一信息使用第五字段指示用于第三信息传输的时域资源配置，该第五字段可以是第一信息中的时域资源配置指示字段。本申请实施例第一信息可以通过第四字段/或第五字段实现对不同类型终端传输信息所用的时域资源配置的指示。
在一种可能的实现方式中，所述第一信息还包括第六字段；所述第六字段指示是否允许所述第一通信设备接入运营商网络；或，所述第六字段指示是否允许所述第一通信设备接入服务小区；或，所述第六字段指示定时配置信息，所述定时配置信息指示所述第一通信设备和所述第二通信设备通信的定时参数。在该方案中，第二通信设备可以在第一信息中指示定时配置信息，从而第一通信设备可以按照该定时配置信息与第二通信设备进行通 信，提高通信的灵活性，实现不同业务对定时通信的需求。
在一种可能的实现方式中，所述第一信息还包括第七字段；所述第七字段指示第一状态，所述第一状态指示不允许所述第一通信设备的接入；或，所述第七字段指示第二状态，所述第二状态指示允许所述第一通信设备的接入，且所述第二状态还指示所述第二信息传输的参数配置信息。在该方案中，本申请实施例中，第二状态指示允许第一通信设备的接入，且第二状态还指示第二信息传输的参数配置信息，因此指示允许第一通信设备的接入和指示第二信息传输的参数配置信息可以联合编码，从而达到减少第一信息的比特开销的目的。
第二方面，本申请实施例还提供一种通信方法，包括：确定用于第二信息传输的第二资源；在第一资源上向第一通信设备发送第一信息，所述第一资源以及所述第一信息指示所述第二资源；在所述第二资源上发送所述第二信息；或，在所述第二资源上接收所述第二信息。在该方案中，第二通信设备在第一资源上向第一通信设备发送第一信息，第一通信设备在第一资源上可接收到该第一信息，第一资源以及第一信息指示用于第二信息传输的第二资源，即第一资源与第一信息共同用于指示该第二资源，因此针对第二资源的指示不仅仅依赖于第一信息，还可以使用传输第一信息的第一资源，从而减少了第一信息指示第二资源时的指示开销。
在一种可能的实现方式中，所述第一信息指示所述第二资源的资源长度；和/或，所述第一资源用于确定所述第二资源的起始资源。在该方案中，第一资源指示第二资源的起始资源，第一信息指示第二资源的资源长度，因此本申请实施例中第二资源可以通过第一资源结合第一信息的方式进行指示，因此针对第二资源的指示不仅仅依赖于第一信息，相比于通过第一信息本身从而减少了第一信息指示第二资源时的指示开销。
在一种可能的实现方式中，所述第一资源的起始资源或结束资源，与所述第二资源的起始资源之间满足预设的关系。在该方案中，第一资源的起始资源或结束资源，与第二资源的起始资源之间满足预设的关系。该预设的关系可以根据具体场景灵活设置，例如在通信协议中预先定义该预设的关系，或者该预设的关系由第二通信设备通知给第一通信设备。在确定出第一资源的起始资源或结束资源之后，根据该第一资源的起始资源或结束资源确定第二资源的起始资源，即第一资源和第二资源的起始资源之间满足预设的特定关系，从而第一通信设备在确定出第一资源时，就可以基于该第一资源确定出第二资源的起始资源。
在一种可能的实现方式中，所述第一信息中的P个比特指示所述第二资源的资源长度；所述P的取值是预先定义的；或，所述P的取值为log 2N，所述N是根据所述第一通信设备的带宽、所述第一资源或所述第二资源所在的载波宽度、所述第一资源或所述第二资源所在的带宽分段BWP大小、所述第一资源或所述第二资源所在的控制资源集coreset的大小、所述第一资源或所述第二资源所在的搜索空间的资源大小、子载波间隔、资源单元的大小、所述第二资源所在的频率范围中的一种或多种确定，其中，所述资源单元包括一个或多个的资源块。在该方案中，预先规定该P的取值大小，例如预先规定P为5，或者6或者其它数值等，例如第一信息中存在5个比特的字段用于指示第二资源的资源长度，无论所指示的第二资源的资源长度为多少，第一信息中都只使用5个比特的字段指示第二资源的资源长度，保证不同带宽下第二资源指示需要的比特数相同，有利于第一信息的格式统一， 简化通信双方的处理复杂度。另外，第一通信设备和第二通信设备都可以通过N的取值确定P的取值，例如P等于log 2N，从而第一通信设备和第二通信设备可以确定第一信息中存在log 2N个比特的字段用于指示第二资源的资源长度。
在一种可能的实现方式中，所述第二资源的起始资源是所述第一资源中的第1个资源单元；或，所述第二资源的起始资源是所述第一资源中的第i+1个资源单元，所述i的值包括如下至少一种：M/4、M/2、3M/4、M，其中，所述M是所述第一资源包含的资源单元个数；或，所述第二资源的起始资源是所述第一资源中的预先规定的资源单元。在该方案中，第二资源的起始资源是第一资源中的第1个资源单元，从而第一通信设备可以在确定第一资源之后，根据第一资源的第1个资源单元确定出第二资源的起始资源，不需要在第一信息来指示第二资源的起始资源，从而节省第一信息的指示开销。第二资源的起始资源是第一资源中的第i+1个资源单元，从而第一通信设备可以在确定第一资源之后，根据第一资源的第i+1个资源单元确定出第二资源的起始资源，不需要在第一信息来指示第二资源的起始资源，从而节省第一信息的指示开销。第二资源的起始资源是第一资源中的预先规定的资源单元，从而第一通信设备可以在确定第一资源之后，根据预先规定确定出第二资源的起始资源，不需要在第一信息来指示第二资源的起始资源，从而节省第一信息的指示开销。
在一种可能的实现方式中，所述资源单元的大小根据所述第一通信设备的带宽、所述第一资源或所述第二资源所在的BWP大小、所述第一资源的资源大小、所述第二信息对应的子载波间隔中的一种或多种确定。在该方案中，资源单元表示的是资源的调度粒度，一个资源单元具体包括一个或多个的资源块，资源单元的大小可以有多种，例如该资源单元可以根据第一通信设备的带宽确定，或者资源单元根据第一资源或第二资源所在的BWP大小确定，或者资源单元根据第一资源的资源大小确定，或者资源单元根据第二信息对应的子载波间隔确定。或者资源单元根据带宽、BWP大小、资源大小、子载波间隔共同确定。这样，资源单元的大小是灵活可配置的，因此就可以保证不同子载波间隔、不同带宽情况下需要的资源指示信息的比特数保持不变。

请参阅图2所示，为本申请实施例提供的一种通信方法的流程方框示意图，例如第一通信设备可以是前述的终端设备，第二通信设备可以是前述的网络设备。本申请实施例提供的数据传输方法中，后续步骤201、步骤202、步骤204从第二通信设备一侧进行说明，步骤203和步骤205从第一通信设备一侧进行说明，主要包括如下步骤：
201、第二通信设备确定用于第二信息传输的第二资源。
其中，第二通信设备确定第二资源，该第二资源是传输第二信息所使用的资源，传输第二信息可以是指发送第二信息，或者接收第二信息等。
第二资源可以是指一个或多个的资源，第二资源可以包括如下至少一种：频率资源、时间资源、空间资源、码域资源、功率、波束、序列中的一种或多种；或，第二资源可以包括如下至少一种：资源块、子载波、子载波间隔(sub carrier spacing，SCS)、载波、带宽分段(bandwidth part，BWP)、参考信号、同步信息块(synchronization signal block，SSB)、控制资源集(control resource set，coreset)、搜索空间、波束相关的配置、载频、带宽(band)、控制信道元素、控制信道元素组、资源块组、天线端口中的一种或多种。
本申请实施例中，第二通信设备可以根据调度第二信息的实际场景灵活的确定该第二资源。例如，第二通信设备可以确定第二资源的起始资源和资源长度，该第二资源可用于调度第二信息，第二信息可以是系统消息，或数据，或控制信息，或同步信息块，或参考信号等，具体可以应用场景确定第二信息的实现方式。
202、第二通信设备在第一资源上向第一通信设备发送第一信息，第一资源以及第一信息指示第二资源。
在本申请实施例中，第二通信设备确定需要指示的第二资源之后，第二通信设备可以 生成第一信息，第二通信设备使用发送该第一信息的第一资源以及该第一信息共同指示第二资源，例如第一资源以及第一信息可以指示第二资源的资源设置情况，从而使得第一通信设备在第一资源上接收到第一信息之后，第一通信设备使用第一资源以及第一信息共同确定出第二资源。例如第一通信设备使用第一资源以及第一信息共同确定出第二资源的资源设置情况，从而第一通信设备可以确定出第二通信设备所指示的第二资源。
其中，第一资源包括一个或多个资源。该第一资源可以是下行控制信息(downlink control information，DCI)实际占用的资源，或者是DCI所在的控制资源集，或控制资源集对应的物理资源块(physical resource block，PRB)，或控制资源集对应的BWP。
第一信息具体可以是DCI，或者是其他高层信令，如无线资源控制(radio resource control，RRC)信令或媒体接入控制层控制单元(media access control control element，MAC CE)，此处不做限定。
在本申请的一些实施例中，第一信息指示第二资源的资源长度；和/或，第一资源用于确定第二资源的起始资源。
其中，第二通信设备需要向第一通信设备指示第二资源的资源设置，例如第二资源的资源设置包括第二资源的资源长度和起始资源，第二通信设备可以使用第一信息指示第二资源的资源长度，例如第一信息中携带有长度指示字段，该长度指示字段可以指示第二资源的资源长度，例如该长度指示字段可以通过第一信息中的保留字段来实现，或者第一信息中可以扩展一个长度指示字段，第一信息中扩展的长度指示字段可指示第二资源的资源长度。另外，第二通信设备还可以使用第一资源来指示第二资源的起始资源。其中，第二资源的起始资源是指第二资源中的第一个资源位置，例如第二资源的起始资源可以是第二资源的频域起始位置。本申请实施例中，第一资源指示第二资源的起始资源，第一信息指示第二资源的资源长度，因此本申请实施例中第二资源可以通过第一资源结合第一信息的方式进行指示，因此针对第二资源的指示不仅仅依赖于第一信息，相比于通过第一信息本身从而减少了第一信息指示第二资源时的指示开销。
本申请的一些实施例中，第一资源的起始资源或结束资源，与第二资源的起始资源之间满足预设的关系。该预设的关系可以根据具体场景灵活设置，例如在通信协议中预先定义该预设的关系，或者该预设的关系由第二通信设备通知给第一通信设备。在确定出第一资源的起始资源或结束资源之后，根据该第一资源的起始资源或结束资源确定第二资源的起始资源，即第一资源和第二资源的起始资源之间满足预设的特定关系，从而第一通信设备在确定出第一资源时，就可以基于该第一资源确定出第二资源的起始资源。
具体的，第一资源的起始资源与第二资源的起始资源相同。即，第一通信设备根据所述第一信息所在的第一资源，确定所述第二资源，例如，确定所述第二资源的频域起始位置。如图3所述，以第一资源和第二资源为频域资源为例，控制资源集上传输有第一信息，第一信息可以是DCI。第二通信设备在第一资源上向第一通信设备发送DCI，第一通信设备可以根据DCI的频率资源确定用于第二信息传输的第二资源的起始资源，第一通信设备根据DCI中指示的频率资源长度确定第二资源的频率资源长度。具体的，第一通信设备和第二通信设备都可以预先配置DCI到第二资源的映射规则，其中，预先配置可以是通信协议标准中预先定义DCI到第二资源的映射规则，第一通信设备和第二通信设备在出厂时按照 该通信协议标准预先配置DCI到第二资源的映射规则，或者，第二通信设备中预先配置DCI到第二资源的映射规则，在第一通信设备和第二通信设备在进行通信之前，第二通信设备通过信令(如高层信令)向第一通信设备指示DCI到第二资源的映射规则，从而第一通信设备可以根据该信令预先配置DCI到第二资源的映射规则。其中，DCI到第二资源的规则可以是以DCI的频域资源起始位置作为第二资源的频域起始位置，该频域资源起始位置可以是资源索引(index)或者资源序号(number)最低的频域位置。第二通信设备在DCI中指示第二资源的频域资源长度，则第一通信设备接收到该第一信息之后，就可以解析该第一信息，确定出第二资源的频域资源长度。
在本申请的另一些实施例中，如图4所述，第一资源的结束资源与第二资源的起始资源之间存在偏移量。所述偏移量可以是预设的，即第一通信设备可以通过第一资源的结束资源来确定第二资源的起始资源，例如第一通信设备将第一资源的结束资源作为基准，按照预设的偏移量进行偏移，以得到第二资源的起始资源。
举例说明如下，第一通信设备和第二通信设备可以预先配置DCI到第二资源的映射规则。如DCI的频域资源结束位置、设置DCI和被调度资源之间存在固定的偏移值，第一通信设备按照该偏移值确定第二资源的起始资源。其中，频域资源结束位置可以是资源索引(index)或者资源序号(number)最高的频域位置。
在本申请的一些实施例中，第一信息中的P个比特指示第二资源的资源长度；
P的取值是预先定义的；或，
P的取值为log 2N，N是根据第一通信设备的带宽、第一资源或第二资源所在的载波宽度、第一资源或第二资源所在的带宽分段BWP大小、第一资源或第二资源所在的控制资源集coreset的大小、第一资源或第二资源所在的搜索空间的资源大小、子载波间隔、资源单元的大小、第二资源所在的频率范围中的一种或多种确定，其中，资源单元包括一个或多个的资源块。
进一步的，第二资源的频域资源长度以及起始资源可以和第一资源所属的搜索空间或控制资源集的频域资源相同。
其中，第一信息指示第二资源的资源长度。例如，第二通信设备在第一信息中指示了第二资源的资源长度，第一信息中存在P个比特的字段用于指示第二资源的资源长度。P的取值具有多种实现方式，例如P的取值可以是预先定义的，即预先规定该P的取值大小，例如预先规定P为5，或者6或者其它数值等，例如第一信息中存在5个比特的字段用于指示第二资源的资源长度，无论所指示的第二资源的资源长度为多少，第一信息中都只使用5个比特的字段指示第二资源的资源长度，保证不同带宽下第二资源指示需要的比特数相同，有利于第一信息的格式统一，简化通信双方的处理复杂度。
另外，第一通信设备和第二通信设备都可以通过N的取值确定P的取值，例如P等于log 2N，从而第一通信设备和第二通信设备可以确定第一信息中存在log 2N个比特的字段用于指示第二资源的资源长度。N为第二资源的资源长度的最大值。具体的，N是根据第一通信设备的带宽、第一资源或第二资源所在的载波宽度、第一资源或第二资源所在的带宽分段大小、第一资源或第二资源所在的控制资源集的大小、第一资源或第二资源所在的搜索空间的资源大小、子载波间隔、资源单元的大小、第二资源所在的频率范围中的一种或多 种确定，不限定的是，N的取值可以是使用上述的一种参数确定出来的，也可以是使用上述的多个参数的组合共同确定出来的。例如，第一信息可以是DCI，第二信息可以是系统消息块(system information block，SIB)，传输第一信息的第一资源所在的载波宽度和传输第二信息的第二资源所在的载波宽度相等。
本申请实施例中，资源单元可以是调度资源的粒度，即第一资源和第二资源在调度时都是以资源单元为单位的，例如，第一资源包括3个资源单元，则表示每次调度第一资源时调度了3个资源单元。具体的，一个资源单元可以包括一个或多个的资源块，接下来详细举例说明资源单元包括的资源块个数。
例如，第一通信设备最大支持5M带宽的传输，通信系统带宽为20M，则N的取值只能为第一通信设备最大支持的5M带宽对应的资源单元个数，如前述举例说明中，子载波间隔为15kHz，5M带宽包括25个RB，即N＝25。
例如，第一通信设备最大支持10M带宽的传输，第二资源所在的载波宽度或BWP大小为5M，则N的取值只能为第二资源所在的载波宽度或BWP大小的5M带宽对应的资源个数，如前述举例说明中，子载波间隔为15kHz，5M带宽包括25个RB，即N＝25。
例如，通信协议规定初始接入时，系统消息的频域资源范围和调度系统消息的DCI所在的资源集合相同，即N的值为第一资源或第二资源所在的控制资源集的大小或搜索空间的资源大小。如第一资源所在的控制资源集的大小为48个RB，则N＝48。
例如，第一通信设备的子载波间隔为15kHz，5M带宽包括25个RB，即N＝25；若子载波间隔为30kHz，5M带宽包括12个RB，即N＝12。
在本申请的一些实施例中，NR通信系统中频率范围可分为低频段和高频段，具体的，定义低于6GHz的频率范围为低频段，高于6GHz的频率范围为高频段。针对不同的频率范围，通信设备支持的子载波间隔、带宽会有所区别，如高频段支持更高的子载波间隔，更大的带宽范围。因而，N的值在不同频段的情况下可以取值不相同。如通信设备在低频段支持的带宽为10MHz，子载波间隔为15kHz，则N＝50；通信设备在高频段支持的带宽为20MHz，120kHz的子载波间隔，则N＝12。对于N的取值取决于应用场景，此处不做限定。
例如，第一信息中需要使用比特数(bits)为log 2N，来指示第二资源的资源长度。以子载波间隔为15kHz、5M带宽为例，5M带宽可包括25个RB，因此第一信息需要5bits指示第二资源的资源长度，对于10M带宽，可以包括50个RB，因此第一信息需要6bits指示第二资源的资源长度，对于20M带宽，可以包括100个RB，因此第一信息需要7bits指示第二资源的资源长度，对于40M带宽，可以包括200个RB，因此第一信息需要8bits指示第二资源的资源长度。因此本申请实施例中，可以根据实际带宽包括的RB个数来确定P的取值，从而大大减小频域资源指示的比特数开销。
例如，若只能通过下行控制信息指示第二资源的起始资源和资源长度，对于5M带宽，若需要log2(25*(25+1)/2)＝9bits，10M带宽需要log2(50*(50+1)/2)＝11bits，20M带宽需要log2(100*(100+1)/2)＝13bits，40M带宽需要log2(200*(200+1)/2)＝15bits。相比于本申请实施例中第一信息中包括P个比特的指示方式，第一信息中需要使用比特数为log 2N，可以极大减少频域资源指示的比特数开销。并且本申请实施例中，同样保证了第二资源的指示灵活性，因为DCI是在预配置的控制资源集中由第二通信设备选择合适的资源来传输 DCI的，DCI的频域资源起始位置是可以变化的，所以第二通信设备可以根据所需要的第二资源的频域资源情况，灵活的选取DCI的起始资源位置，以此来匹配要调度的第二资源的资源位置。
进一步的，在不同带宽范围内的资源块数目和子载波间隔之间满足预设的相应关系。例如，在子载波间隔＝15kHz的情况下，5M带宽可以包括25个RB。当然还可以定义多种子载波间隔，例如包括30kHz、60kHz、120kHz、240kHz。如5M带宽，在子载波间隔＝30kHz时，第二资源的资源长度的最大值N＝12，一个资源单元可以包括1个RB，按照log 2N计算，则需要的指示信息的比特数为4bits；又如，在子载波间隔＝60kHz的情况下，需要指示信息的比特数为3bits。
另外，资源单元包括一个或多个的资源块。举例说明如下，一个资源单元可以包括多个资源块(resource block，RB)，例如在子载波间隔为15kHz、且通信设备的带宽为5M的情况下，资源单元为1个RB，在子载波间隔为15kHz、通信设备的带宽为20M的情况下，资源单元为4个RB，在子载波间隔为30kHz、且通信设备的带宽为20M的情况下，资源单元为2个RB。
其中，一个资源单元可以包括多个RB，例如在子载波间隔为15kHz，带宽为5M的情况下，资源单元可以为1个RB，在子载波间隔为15kHz，带宽为20M的情况下，资源单元为4个RB，在子载波间隔为30kHz，带宽为20M的情况下，资源单元为2个RB，一个资源单元具体包括几个RB是根据子载波间隔、带宽来确定的。这样就可以保证不同子载波间隔、不同带宽情况下需要的资源指示信息的比特数保持5bits不变。
在本申请的一些实施例中，资源单元的大小根据第一通信设备的带宽、第一资源或第二资源所在的BWP大小、第一资源的资源大小、第二信息对应的子载波间隔中的一种或多种确定。
具体的，资源单元表示的是资源的调度粒度，一个资源单元具体包括一个或多个的资源块，资源单元的大小可以有多种，例如该资源单元可以根据第一通信设备的带宽确定，或者资源单元根据第一资源或第二资源所在的BWP大小确定，或者资源单元根据第一资源的资源大小确定，或者资源单元根据第二信息对应的子载波间隔确定。或者资源单元根据带宽、BWP大小、资源大小、子载波间隔共同确定。这样，资源单元的大小是灵活可配置的，因此就可以保证不同子载波间隔、不同带宽情况下需要的资源指示信息的比特数保持不变。
举例说明如下，为了节省第一信息的比特数开销，可以规定频域资源的资源单元为n个资源块，例如一个资源单元包括2个RB，子载波间隔为15kHz，带宽为20M，资源指示信息需要6bits。或者，资源单元的大小根据配置的或者可用的的第一通信设备的带宽，或控制资源集的频域宽度或控制信号的频域长度来确定，如第一通信设备的可用带宽<5M，则资源单元的大小为1个资源块；若第一通信设备的可用带宽为5至10M，则资源单元的大小为2个资源块，若第一通信设备的可用带宽为10至20M，则资源单元的大小为4个资源块。本申请实施例可以保证不同带宽下，频域资源的指示比特数相同，例如资源指示信息占用的比特数都为5bits，使得不同带宽下频域资源指示需要的比特数相同，有利于第一信息的格式统一，简化通信双方的处理复杂度。
另一个举例说明如下，不同的子载波间隔情况下，如子载波间隔＝15kHz，带宽为5M时，资源单元的大小为1个资源块，则资源指示信息占用的比特数为5bits，子载波间隔＝60kHz，带宽为80M，资源单元的大小为4个资源块，则资源指示信息占用的比特数为5bits。
在本申请的一些实施例中，还可以根据第一资源的大小确定资源单元的大小，如第一资源的大小和资源单元的大小之间存在预设的映射关系。例如，资源单元的大小与第一资源的大小成正比关系，如果第一资源的频域资源大小为4个控制信道单元(control channel element，CCE)，则资源单元的大小为1个RB；如果第一资源的频域资源大小为8个CCE，则资源单元的大小为2个RB。
在本申请的一些实施例中，第二资源的起始资源是第一资源中的第1个资源单元；或，
第二资源的起始资源是第一资源中的第i+1个资源单元，i的值包括如下至少一种：M/4、M/2、3M/4、M，其中，M是第一资源包含的资源单元个数；或，
第二资源的起始资源是第一资源中的预先规定的资源单元。
其中，第二资源的起始资源具有多种配置方式，例如第二通信设备可以设置第二资源的起始资源是第一资源中的第1个资源单元，因此第一通信设备在确定出第一资源中的第1个资源单元时，就可以确定该第1个资源单元是第二资源的起始资源，对于资源单元的说明，详见前述内容，此处不再赘述。本申请实施例中，第二资源的起始资源是第一资源中的第1个资源单元，从而第一通信设备可以在确定第一资源之后，根据第一资源的第1个资源单元确定出第二资源的起始资源，不需要在第一信息来指示第二资源的起始资源，从而节省第一信息的指示开销。
例如，第二通信设备可以设置第二资源的起始资源是第一资源中的第i+1个资源单元，i的值包括如下至少一种：M/4、M/2、3M/4、M，其中，M是第一资源包含的资源单元个数。根据子载波间隔和第一通信设备的带宽和每个资源单元包括的资源块个数可以确定出第一资源包含的资源单元个数M，再通过M和i的关系，可以确定出第二资源的起始资源。不限定的是，i的值还可以包括如下至少一种：

M等，具体根据应用场景确定i的取值。其中，

代表向下取整运算。本申请实施例中，第二资源的起始资源是第一资源中的第i+1个资源单元，从而第一通信设备可以在确定第一资源之后，根据第一资源的第i+1个资源单元确定出第二资源的起始资源，不需要在第一信息来指示第二资源的起始资源，从而节省第一信息的指示开销。
例如，第二资源的起始资源是第一资源中的预先规定的资源单元，第二通信设备可以根据需要调度的第二信息、通信系统的带宽等规定第一资源中的哪个资源单元作为第二资源的起始资源。本申请实施例中，第二资源的起始资源是第一资源中的预先规定的资源单元，从而第一通信设备可以在确定第一资源之后，根据预先规定确定出第二资源的起始资源，不需要在第一信息来指示第二资源的起始资源，从而节省第一信息的指示开销。
在本申请的一些实施例中，第一信息还指示用于第三信息传输的第三资源，其中，第三信息是第二通信设备发送给第三通信设备的信息，或，第三信息是第二通信设备接收来自第三通信设备的信息；
第三通信设备的带宽大于第一通信设备的带宽，其中，带宽包括如下至少一种：下行带宽、上行带宽、系统最大带宽、支持的最大带宽。
具体的，第一通信设备的带宽可以包括如下至少一种：第一通信设备的下行带宽、第一通信设备的上行带宽、通信系统的最大带宽、第一通信设备支持的最大带宽，通信系统包括：第一通信设备、第二通信设备和第三通信设备。
第三通信设备的带宽可以包括如下至少一种：第三通信设备的下行带宽、第三通信设备的上行带宽、通信系统的最大带宽、第三通信设备支持的最大带宽，通信系统包括：第一通信设备、第二通信设备和第三通信设备。
其中，第一通信设备的下行带宽是指第一通信设备在频域进行下行传输的最大频域宽度，第一通信设备的上行带宽是指第一通信设备在频域进行上行传输的最大频域宽度，通信系统的最大带宽是指通信系统在频域传输的最大频域宽度，第一通信设备支持的最大带宽是指第一通信设备在频域传输时能够支持的最大频域宽度。类似的，第三通信设备的带宽与第一通信设备的带宽的含义相类似，此处不再详述。
其中，第一信息和第一资源可以指示第二资源，同时该第一信息还可以指示第三资源，例如第一信息中的保留(reserved)字段和第一资源可指示第二资源，该保留字段也可以称为保留域或者保留比特。该第一信息中还可以包括第三资源的指示字段，通过第三资源的指示字段来指示第三资源的资源设置。例如，第一信息可以是DCI，该DCI中包括：频域资源分配字段、时域资源分配字段、物理资源块-虚拟资源块(virtual resource block-physical resource block，VRB-PRB)映射字段、调制编码方式指示字段、冗余版本指示字段、系统消息指示字段。其中，频域资源分配字段用于指示频域资源的起始位置和长度，时域资源分配字段用于指示时域资源的起始位置、长度等信息，VRB-PRB映射字段用于指示采用的资源映射方式，调制编码方式(modulation and coding scheme，MCS)指示字段用于指示选择MCS表格中的哪一个值，冗余版本指示字段用于指示使用的冗余版本号，系统消息指示字段用于指示使用的系统消息。
需要说明的是，第一通信设备可以解析第一信息中的VRB-PRB映射字段和冗余版本指示字段，以确定出第二通信设备指示的资源映射方式和冗余版本号，同样的，第三通信设备可以解析第一信息中的VRB-PRB映射字段和冗余版本指示字段，以确定出第二通信设备指示的资源映射方式和冗余版本号。因此本申请实施例中，第一通信设备可以复用第一信息中的VRB-PRB映射字段和冗余版本指示字段，从而在第一信息中不需要单独为第一通信设备指示资源映射方式和冗余版本号，节省第一信息的指示开销。
本申请实施例中，第三资源可用于第三信息的传输，例如第三信息是第二通信设备发送给第三通信设备的信息，或，第三信息是第二通信设备接收来自第三通信设备的信息，例如第三信息可以是系统消息，或数据，或控制信息，或同步信息块，或参考信号等，具体可以根据应用场景确定第二信息的实现方式。本申请实施例中，第一信息可以同时用于指示第二资源，以及指示第三资源，因此第二通信设备可以通过一条第一信息实现针对第一通信设备和第三通信设备各自所需资源的指示，提高了向各种类型的终端设备指示资源的效率，且所使用的第一信息所需要的指示开销很小。
在本申请实施例中，第三通信设备的带宽大于第一通信设备的带宽，即第一通信设备的带宽相对于第三通信设备的带宽，可以是窄带。不限定的是，第一通信设备的带宽还可以等于第三通信设备的带宽，具体实现方式取决于应用场景。
需要说明的是，第一通信设备的复杂度还可以低于第三通信设备的复杂度，例如，第一通信设备的天线数目更少、功率更低、处理速度或能力更低、仅支持半双工、控制信道盲检测能力更低等。
在本申请实施例中，第一通信设备可以是第二类终端，第二类终端区别于3GPP Rel-15已定义的普通终端(即第三通信设备)，第一通信设备的部分能力与3GPP Rel-15定义的普通终端能力不同，比如第二类终端为带宽能力受限的终端，或为需要功耗节省的终端；第二类终端可能被称为mMTC或NRL(NR light)或REDCAP(reduced capability)终端，此处不做限定。例如，第一通信设备可以是mMTC终端，第三通信设备可以是eMBB终端和/或URLLC终端。
在本申请的一些实施例中，第一信息还包括第一字段，第一字段包括3个比特，第一字段指示用于第二信息传输的调制编码方式MCS；和/或，
第一信息还包括第二字段，第二字段包括5个比特，第二字段指示用于第三信息传输的MCS，第三信息是第三通信设备发送或者接收的信息。
具体的，第一信息还可以用于MCS的指示，例如第一信息中使用第一字段指示用于第二信息传输的MCS，该第一字段可以是第一信息中的保留字段。又如，第一信息使用第二字段指示用于第三信息传输的MCS，该第二字段可以是第一信息中的调制编码方式指示字段。本申请实施例第一信息可以通过第一字段/或第二字段实现对不同类型终端传输信息所用的MCS的指示。
举例说明如下，系统消息无线网络临时标识(system information radio network tempory identity，SI-RNTI)加扰的调制编码方式对应的调制阶数用Qm表示，该Qm的取值不能够大于2，例如Qm＝2对应在MCS表格(table)1包括索引(index)0-9，MCS table2包括index 0-4，MCS table3包括index 0-14。第一通信设备(例如mMTC终端)的调制方式可以在正交相移键控(quadrature phase shift keying，QPSK)，则指示MCS的比特数可以缩减到3bits或4bits。例如，调制编码方式指示字段的比特数为3bits，则调制编码方式指示字段保留8个状态，调制编码方式指示字段的比特数为4bits，则调制编码方式指示字段保留16个状态。或者限制第一通信设备采用更低的编码效率，也可以缩减MCS的比特数，例如限制编码效率低于1，则对应MCS table1包括索引(index)0-6，MCS table2包括index 0-3，MCS table3包括index 0-12，可以缩减调制编码方式指示字段的大小为3bits或者4bits。
在本申请的上述实施例中，第一信息中可以包括第一字段或第二字段，与此实现方式不相同的是，在本申请的另一些实施例中，第一信息还包括第三字段，第三字段指示用于第二信息传输的MCS和第二资源。
具体的，该第三字段可以是调制编码方式指示字段，第三字段除了指示第二信息传输所用的MCS，该第三字段还可以指示第二资源，即第三字段可以实现指示MCS和指示第二资源的联合编码。例如，子载波间隔为15kHz，5M带宽包括25个RB，即UE可调度的最大频率资源数为25，即可以表示25个状态；调制编码方式对应的调制阶数用Qm表示，该Qm的取值等于2，在MCS table1中有10个状态，第三字段可以实现指示MCS和指示第二资源的联合编码，需要250个状态表示，即可用8bits表示。因此，本申请实施例中，第一 信息中只需要通过第三字段就可以实现指示MCS和指示第二资源的联合编码，进一步节省了第一信息的比特数开销。
在本申请的一些实施例中，第一信息还包括：第四字段，第四字段包括2或3个比特，第四字段指示传输所述第二信息的时域资源配置；和/或，
第一信息还包括第五字段，第五字段包括4个比特，第五字段指示传输第三信息的时域资源配置，第三信息是第三通信设备发送或者接收的信息。
具体的，第一信息还可以用于时域资源配置的指示，例如第一信息中使用第四字段指示用于第二信息传输的时域资源配置，该第四字段可以是第一信息中的保留字段。又如，第一信息使用第五字段指示用于第三信息传输的时域资源配置，该第五字段可以是第一信息中的时域资源配置指示字段。本申请实施例第一信息可以通过第四字段/或第五字段实现对不同类型终端传输信息所用的时域资源配置的指示。
例如，第一信息中可以包括第四字段，或者第一信息中可以包括第五字段，第四字段占用的比特数少于第五字段。第四字段包括2或3个比特，例如，第一信息可以是DCI，DCI中的2或3个bits指示预设或预配置的时域资源对应关系，例如该对应关系可以是时域资源的配置指示表格，或者该对应关系可以是时域资源的配置指示列表，或者该对应关系可以是时域资源的配置指示信息集合，后续实施例中以该对应关系为表格进行示例说明。
第一信息中的第五字段可以占用4个比特，例如，时域资源的指示是通过DCI中的4bits指示预设或预配置的时域资源对应关系。其中，预设指的是协议预先规定，在通信设备入网前就已获取到配置时域资源的对应关系，预配置指的是在第一通信设备在接收到DCI之前，第二通信设备通过高层信令将配置时域资源的对应关系发送给第一通信设备，由第一通信设备进行配置得到上述对应关系。其中，高层信令有多种，例如高层信令包括：无线资源控制(radio Resource Control，RRC)。
举例说明如下，在时域资源的配置指示表格中，每一行可以指示数据的时域资源传输信息，包括的参数有：参考信号信息、数据传输映射类型(PDSCH mapping type)、数据和DCI之间的时隙间隔(K0)、数据在时隙中的起始符号位置(S)、数据传输的长度(L)。通过4bits的DCI指示具体采用哪一行的参数配置。例如参考信号信息可以是解调参考信号类型A的位置(dmrs-TypeA-Position)。
接下来以第二资源为时域资源为例，第一信息指示的第二资源可以使用如下的表1，因为第一通信设备的支持带宽可能比较窄，在频域资源受限，但同时又要求保证第一通信设备的覆盖，甚至要求对第一通信设备进行覆盖增强，则可以考虑在时域资源扩展，即采用更长的时域资源。可以配置如下所示的表格1，例如只使用如下表格1中的4行或者8行的参数配置。
表格1中时域长度大于X个符号，如X为4个符号。在实际应用中，可以按照在表1中增加窄带索引(second row index)字段，用于指示第一通信设备的时域资源指示信息对应的索引(index)，该窄带索引只有8个状态，因此只需要3个比特就可以全部指示。即对符号长度大于4的有8个状态进行重新编码索引。
表1为指示时域资源的表格。
Figure PCTCN2019130729-appb-000003
不限定的是，本申请实施例中还可以配置的表格包括小于4行或8行。这样，DCI的指示比特数可以减为2或3bits，减少DCI的指示开销。
在本申请的一些实施例中，第一信息还包括第六字段；
第六字段指示是否允许第一通信设备接入运营商网络；或，
第六字段指示是否允许第一通信设备接入服务小区；或，
第六字段指示定时配置信息，定时配置信息指示第一通信设备和第二通信设备通信的定时参数。
具体的，第二通信设备通过第一信息中第六字段指示是否允许第一通信设备接入运营商网络，或者第六字段指示是否允许第一通信设备接入服务小区。例如第二通信设备不支持mMTC业务，则第六字段可以指示不允许第一通信设备接入运营商网络，或者第六字段指示禁止第一通信设备接入第二通信设备所在的服务小区。或者第二通信设备在第一信息中 的第六字段中指示第二通信设备不接受第一通信设备接入服务小区，即第二通信设备不具备服务第一通信设备的能力。其中，服务小区(serving cell)是指在通信系统中第二通信设备所覆盖的区域，在服务小区内第一通信设备可以通过无线信道与第二通信设备进行通信，例如服务小区可以是一个扇区或一个载波频段。
在本申请的另一些实施例中，第一信息还包括第六字段，该第六字段是第一信息中的保留字段，第六字段指示定时配置信息，该定时配置参数可指示第一通信设备和第二通信设备通信的定时参数，其中，定时参数可以有多种实现方式，例如定时参数可以包括第一通信设备和第二通信设备进行通信的起始时间，又如定时参数可以包括触发通信的触发条件，触发条件可以是第一通信设备和第二通信设备之间传输的数据量小于阈值等，又如定时参数还包括定时器的时长，具体可以根据应用场景确定该定时参数。举例说明如下，当前服务小区的系统容量受限，则可以通过定时配置信息指示终端设备在定时器到期后再接入网络，以此来避免当前小区的负载过大，避免由于过多终端设备接入而导致系统拥塞。本申请实施例中，第二通信设备可以在第一信息中指示定时配置信息，从而第一通信设备可以按照该定时配置信息与第二通信设备进行通信，提高通信的灵活性，实现不同业务对定时通信的需求。
例如，第二通信设备可以在系统消息中包括mMTC的禁止或者允许信息。例如可以在系统消息块(system information block，SIB)或主信息块(master information block，MIB)中通过1个比特传输，具有前向兼容的作用，在不影响第三通信设备(即普通终端)的指示的同时，指示系统是否支持mMTC UE；而且增加该信息可以使基站灵活配置是否支持mMTC(或指示支持FR1的mMTC or FR2mMTC)，同时防止mMTC的UE将legacy UE的DCI信息的保留(reserved)字段的错误解读。其中，FR1(frequency range 1)是指NR系统中带宽小于6GHz的频段，FR2(frequency range2)是指NR系统中带宽大于6GHz的频段。
举例说明如下，SIB中1bit指示是否支持高频mMTC，或者通过MIB中频率信息判断(如频段为6GHz以上，或子载波间隔大于60kHz等)，UE根据能力去匹配是否可以接入该基站，如果MIB中指示在FR2上工作，则UE不接入该基站。
在本申请的一些实施例中，第一信息还包括第七字段；
第七字段指示第一状态，第一状态指示第二通信设备不允许第一通信设备的接入；或，
第七字段指示第二状态，第二状态指示允许第一通信设备的接入，且第二状态还指示第二信息传输的参数配置信息。
在本申请的另一些实施例中，第一信息还包括第七字段，该第七字段是第一信息中的保留字段。具体的，第二通信设备是否允许接入第一通信设备能够和其他字段联合编码，通过第七字段的不同状态取值可以分别指示不同的内容。其中，第一状态指示是否允许第一通信设备接入与前面实施例中的第六字段中的禁止或允许信息的含义类似，这里不再赘述。第二信息传输的参数配置信息可以是重复次数、第一资源的指示信息、MCS指示信息等。本申请实施例中，第二状态指示允许第一通信设备的接入，且第二状态还指示第二信息传输的参数配置信息，因此指示允许第一通信设备的接入和指示第二信息传输的参数配置信息可以联合编码，从而达到减少第一信息的比特开销的目的。
以第二信息传输的参数配置信息具体为资源重复信息为例，第二通信设备可以在系统 消息中包括资源重复信息，该资源重复信息可以包括数据的重复次数和/或控制信息的重复次数。因为mMTC需要考虑降低UE的复杂度或成本，降低UE支持的接收和/或发送带宽。通信系统中mMTC业务需要对通信系统的覆盖(coverage)进行增强，比如在当前通信系统的覆盖基础上进行额外的20dB或15dB的覆盖增强。覆盖增强是指系统中信号的传输能够保证信道质量差的第一通信设备能可靠的和第二通信设备进行通信。可以通过在时域重复的方法提高mMTC业务的可靠性，因而在调度SIB的DCI中可以增加指示传输重复次数的信息域，来提高SIB传输的可靠性。
具体的，以第二信息传输的参数配置信息为重复次数为例，在第一信息中，若指示重复次数和指示允许第一通信设备的接入，分别进行独立编码，则第一信息中指示数据的重复次数需要3bits，第一信息中指示控制信息的重复次数需要2bits，第一信息中指示允许第一通信设备的接入需要1个比特，因此第一信息中共需要6个比特。若第一信息中指示重复次数和指示允许第一通信设备的接入进行联合编码，其中，指示数据的重复次数需要包括4个状态、指示控制信息的重复次数需要包括3个状态，指示允许第一通信设备的接入需要1个状态，因此联合编码之后，共需要指示8种状态即可，因此第一信息中只需要使用3bits就可以指示重复次数和指示允许第一通信设备的接入，极大的降低了指示开销。
例如，指示重复次数和指示允许第一通信设备的接入进行联合编码，如第七字段占用3bits，如下表2所示，用状态000来指示不允许第一通信设备的接入，即第二通信设备不支持mMTC，用状态001至111，来指示,允许第一通信设备的接入，并且状态001至111中指示数据的重复次数需要包括4个状态、指示控制信息的重复次数需要包括3个状态，例如数据的重复次数包括：2、4、8、16，控制信息的重复次数包括：1、2、4。
表2为指示控制信息的重复次数和指示数据的重复次数的联合编码结果。
Figure PCTCN2019130729-appb-000004
通过上述举例说明可知，本申请实施例中，通过指示重复次数可以实现多次重复传输，可以保证数据和控制信息的可靠性，另外，通过联合编码还可以节省第一信息的比特开销。
203、第一通信设备在第一资源上接收来自第二通信设备的第一信息，第一资源以及第一信息指示用于第二信息传输的第二资源。
在本申请实施例中，第二通信设备确定需要指示的第二资源之后，第二通信设备可以生成第一信息，第二通信设备使用发送该第一信息的第一资源以及该第一信息共同指示第二资源，例如第一资源以及第一信息可以指示第二资源的资源设置情况，从而使得第一通信设备在第一资源上接收到第一信息之后，第一通信设备使用第一资源以及第一信息共同 确定出第二资源。例如第一通信设备使用第一资源以及第一信息共同确定出第二资源的资源设置情况，从而第一通信设备可以确定出第二通信设备所指示的第二资源。
在本申请的一些实施例中，第一通信设备除了执行前述步骤203，第一通信设备还可以执行如下的方法：
第一通信设备根据第一信息确定第二资源的资源长度；和/或，
第一通信设备根据第一资源确定第二资源的起始资源。
本申请实施例中，第一资源用于确定第二资源的起始资源，即第一资源和第二资源的起始资源之间满足预设的特定关系，从而第一通信设备在确定出第一资源时，就可以基于该第一资源确定出第二资源的起始资源。具体的，第一资源的起始资源与第二资源的起始资源相同。
举例说明如下，以第一资源和第二资源为频域资源为例，第一信息可以是DCI。第二通信设备在第一资源上向第一通信设备发送DCI，第一通信设备可以根据DCI的频率资源确定用于第二信息传输的第二资源的频率资源起始位置，第一通信设备根据DCI中指示的频率资源长度确定第二资源的频率资源长度。具体的，第一通信设备和第二通信设备可以预设DCI到第二资源的映射规则。如以DCI的频域资源起始位置(即资源索引(index)/个数(number)最低)作为第二资源的频域起始位置。第二通信设备在DCI中指示第二资源的频域资源长度，则第一通信设备接收到该第一信息之后，就可以解析该第一信息，确定出第二资源的频域资源长度。
在本申请的另一些实施例中，第一资源的结束资源与第二资源的起始资源之间存在预设的偏移量，即第一通信设备可以通过第一资源的结束资源来确定第二资源的起始资源，例如第一通信设备将第一资源的结束资源作为基准，按照预设的偏移量进行偏移，以得到第二资源的起始资源。
举例说明如下，第一通信设备和第二通信设备可以预设DCI到第二资源的映射规则。如DCI的频域资源结束位置、设置DCI和被调度之间存在固定的偏移值，第一通信设备按照该偏移值确定第二资源的起始资源。
204、第二通信设备在第二资源上发送第二信息；或，在第二资源上接收第二信息。
205、第一通信设备在第二资源上接收第二信息；或，在第二资源上发送第二信息。
其中，第一通信设备在获取到第二通信设备指示的第二资源之后，第一通信设备可以使用该第二资源进行第二信息的收发。例如第二通信设备在第二资源上发送第二信息，则第一通信设备可以确定出第二资源的起始资源和资源长度，从而第一通信设备可以在第二资源上接收第二信息。类似的，第一通信设备可以确定出第二资源的起始资源和资源长度，第一通信设备在第二资源上发送第二信息，则从而第二通信设备可以在第二资源上接收第二信息。
通过前述实施例的举例说明可知，第二通信设备在第一资源上向第一通信设备发送第一信息，第一通信设备在第一资源上可接收到该第一信息，第一资源以及第一信息指示用于第二信息传输的第二资源，即第一资源与第一信息共同用于指示该第二资源，因此针对第二资源的指示不仅仅依赖于第一信息，从而减少了第一信息指示第二资源时的指示开销。由于第一通信设备可以使用第一资源和第一信息来共同确定出第二资源，因此第一资源和 第一信息可以根据第二通信设备灵活调度第二资源的需求进行配置，保证了可调度资源的灵活性。
