Description

通信方法和装置 技术领域
本申请涉及通信技术领域，尤其涉及一种通信方法和装置。
背景技术
增强型机器类通信(enhanced Machine Type Communication，eMTC)系统及其他演化系统是在长期演进系统(Long Term Evolution，LTE)基础上衍生的系统，它在LTE系统中、并在LTE频段中进行工作。由于eMTC终端设备的成本较为低廉，能力相对较弱，所以eMTC终端设备不允许同时接收两个不同窄带的信号。
现有技术中，当下列其他信号的一种或多种与预配置资源(preconfigured uplink resource transmission,PUR)或PUR的搜索空间在时间上有交叠的时候，终端设备不能够同时接收PUR/PUR搜索空间传输的信号和其他信号，其中，其他信号包括寻呼(paging)的控制信息、paging信息、广播的控制信息、广播的数据信息和广播信号的调度控制信息中的一种或多种。当PUR/PUR搜索空间与传输广播的控制信息、广播的数据信息和广播信号的调度控制信息的信号的搜索空间发生碰撞之后，由于广播的控制信息、广播的数据信息和广播信号的调度控制信息优先级较低，这些信息会被直接丢弃。而PUR/PUR搜索空间与传输寻呼消息的搜索空间发生碰撞之后，则会丢弃其中一种信息，也即丢弃PUR搜索空间的信息或丢弃寻呼搜索空间的信息。
然而，上述的方式中，若将寻呼信息丢弃，那么终端设备可能会错过系统消息变更、通知进入连接态以及一些紧急信息的通知，导致用户系统消息变更不及时、进入连接态时延过大以及错过地震海啸等紧急信息通知，错过紧急信息后果可能是不可估量的因此，在PUR/PUR搜索空间与寻呼信息在时域和/或频域存在重叠时，如何进行处理来最小化对终端设备的影响，是目前亟待解决的技术问题。
发明内容
本申请实施例提供一种通信方法和装置，可以避免因未接收到紧急信息造成的损失以及更新延迟造成的传输失败，从而可以最小化对第二设备的影响。
第一方面，本申请实施例提供一种通信方法，包括：
第一设备确定第一信息，所述第一信息用于指示寻呼内容；
在第一搜索空间和第二搜索空间存在资源重叠，或者在所述第一设备使能所述第二设备跳过所述第一资源传输时，所述第一设备通过所述第一搜索空间向所述第二设备发送所述第一信息。
在本方案中，第一信息也可以称为直接指示信息，用于指示寻呼内容。
由于在第一搜索空间和第二搜索空间存在资源重叠，或者在第一设备使能第二设 备跳过第一资源传输时，或者通过高层信令指示第一信息在第一搜索空间中传输时，或者在第一设备配置了第一资源时，第一信息是通过第一搜索空间发送给第二设备的，因此，在第一搜索空间和第二搜索空间发生碰撞时，第二设备只需要检测第一搜索空间，就可以得到第一信息，这样，第二设备通过检测第一搜索空间就可以及时接收到寻呼消息中的紧急信息、系统消息改变等信息，避免因未接收到紧急信息造成的损失以及更新延迟造成的传输失败，从而可以最小化对第二设备的影响。
在一种可能的实现方式中，所述方法还包括：
所述第一设备确定第二信息，所述第二信息用于指示第二设备在第一资源上传输的信号的传输状态；
所述第一设备通过所述第一搜索空间向所述第二设备发送所述第一信息和所述第二信息。
在本方案中，第一设备通过第一搜索空间向第二设备发送第一信息和第二信息，因此，在第一搜索空间和第二搜索空间发生碰撞时，第二设备只需要检测第一搜索空间，就可以得到第一信息和第二信息，这样，第二设备通过检测第一搜索空间就可以及时接收到寻呼消息中的紧急信息、系统消息改变等信息，避免因未接收到紧急信息造成的损失以及更新延迟造成的传输失败，而且可以使得第二设备接收到PUR的反馈信息，避免了不必要的重传或者回退，减少了功率浪费，从而可以最小化对第二设备的影响。
其中，回退是指当PUR传输失败时，或者在第一搜索空间没有接收到PUR反馈信息时，第二设备发起随机接入或者数据早传进入连接态，以发送数据。
在一种可能的实现方式中，所述第一信息包括如下信息中的至少一种：寻呼指示信息、系统消息变更通知信息、地震和海啸警告系统通知信息、商业移动警报服务指示信息、系统架构演化临时移动站标识符S-TMSI、国际移动用户身份IMSI、无线网络临时标识RNTI和接入类型信息，所述寻呼指示信息用于指示所述第二设备的寻呼状态。
在上述方案中，寻呼指示信息用于指示第二设备的寻呼状态，该寻呼状态可以包括第二设备被寻呼，或者也可以包括第二设备没有被寻呼。另外，寻呼指示信息也可以称为无线资源控制(Radio Resource Control，RRC)连接指示信息，即用于指示第二设备是否进入RRC连接态，或者还可以称为RRC连接完成指示信息，即用于指示RRC建立连接完成。进一步地，该寻呼指示信息还可以用于指示第二设备是否发起随机接入或进行数据早传(Early data transmission)等。
另外，系统消息变更通知信息、地震和海啸警告系统通知信息、商业移动警报服务指示信息等信息通过下行控制信息发送给第二设备。寻呼指示信息可以通过高层信令发送给第二设备。寻呼指示信息包括小区RNTI(cell-RNTI，C-RNTI)或第一RNTI，用于指示第二设备进入连接态。

在上述方案中，PUR重传可以指，在预配置上行链路资源中或在部分预配置上行链路资源中进行重传，即不需要动态调度信息(如DCI)调度，而是通过预配置上行链路资源进行重传，但是相应的预配置资源的配置信息可以通过动态调度信息进行重配或更新。调度PUR重传是指第二设备根据第一设备的动态调度信息(如DCI)的调度信息进行重传。
在本方案中，第二设备通过第二信息中的第一指示信息和/或第二指示信息，使得第二设备接收到PUR的反馈信息，避免了不必要的重传或者回退，减少了功率浪费，从而可以最小化对第二设备的影响。
在一种可能的实现方式中，所述第一搜索空间和所述第二搜索空间配置于同一窄带。
在本方案中，第一设备可以将第一搜索空间和第二搜索空间配置在同一窄带中，这样，第二设备可以在该窄带中检测第一搜索空间和第二搜索空间，第二设备可以及时接收到寻呼消息中的紧急信息、系统消息改变等信息，避免因未接收到紧急信息造成的损失以及更新延迟造成的传输失败，而且可以使得第二设备接收到PUR的反馈信息，避免了不必要的重传或者回退，减少了功率浪费，从而可以最小化对第二设备的影响。
在一种可能的实现方式中，所述第一搜索空间用于传输所述第一设备反馈第一资源传输的状态信息和/或调度重传的下行控制信息；所述第二搜索空间用于传输调度寻呼消息的下行控制信息。
在上述方案中，第一搜索空间是指第一资源搜索空间，例如可以为PUR搜索空间(PUR SS)，其可以仅用于传输第一设备反馈第一资源传输的状态信息，也可以仅用于传输调度重传的下行控制信息，还可以同时传输第一设备反馈第一资源传输的状态信息和调度重传的下行控制信息。
另外，第二搜索空间例如可以为Type1-MPDCCH common search space(Type1SS)。

本申请实施例描述的系统架构以及业务场景是为了更加清楚的说明本申请实施例的技术方案，并不构成对于本申请实施例提供的技术方案的限定，本领域普通技术人员可知，随着网络架构的演变和新业务场景的出现，本申请实施例提供的技术方案对于类似的技术问题，同样适用。
下面首先针对本申请实施例适用场景进行简要说明。
当调度寻呼(paging)信息的控制信息、paging信息、调度广播数据的控制信息、广播的数据信息和广播信号的调度控制信息中的一种或多种与预配置资源(preconfigured uplink resource transmission,PUR)或PUR的搜索空间在时间上有交叠的时候，终端设备不能够同时接收PUR/PUR搜索空间传输的信号和这些信号。当PUR/PUR搜索空间与传输广播的控制信息、广播的数据信息和广播信号的调度控制信息的信号的搜索空间发生碰撞之后，由于广播的控制信息、广播的数据信息和广播信号的调度控制信息优先级较低，这些信息会被直接丢弃。而PUR/PUR搜索空间与传输寻呼消息的搜索空间发生碰撞之后，则会丢弃其中一种信息，也即丢弃PUR搜索空间的信息或丢弃寻呼搜索空间的信息。如果丢弃寻呼信息，那么终端设备可能会错过系统消息变更、通知进入连接态以及一些紧急信息的通知，导致用户系统消息变更不及时、进入连接态时延过大以及错过地震海啸等紧急信息通知，错过紧急信息后果可能是不可估量的。因此，在PUR资源/PUR搜索空间与寻呼信息在时域和/或频域存在重叠时，如何进行处理来最小化对终端设备的影响，是本申请实施例需要解决的技术问题。
另外，在现有技术中，第一设备通过第二搜索空间向第二设备发送第一信息。其中，第一搜索空间用于传输第一设备反馈第一资源传输的状态信息和/或调度重传的下行控制信息，第二搜索空间用于传输调度寻呼消息的下行控制信息，第一信息用于指示寻呼内容。但是，上述方式中，如果第一搜索空间和第二搜索空间存在资源重叠时，第一设备通过第二搜索空间向第二设备发送第一信息，终端设备由于无法同时在两个窄带上同时检测第一搜索空间和第二搜索空间，因此可能会错过系统消息变更、通知进入连接态以及一些紧急信息的通知，导致用户系统消息变更不及时、进入连接态时延过大以及错过地震海啸等紧急信息通知。
本申请实施例中考虑到上述问题，提出了一种通信方法，第一设备通过确定第一信息，该第一信息用于指示寻呼内容，在第一搜索空间和第二搜索空间存在资源重叠，或者在第一设备使能第二设备跳过第一资源传输时，或者通过高层信令指示第一信息在第一搜索空间中传输时，或者在第一设备配置了第一资源时，第一设备通过第一搜索空间向第二设备发送第一信息。由于在第一搜索空间和第二搜索空间存在资源重叠，或者在第一设备使能第二设备跳过第一资源传输时，或者通过高层信令指示第一信息在第一搜索空间中传输时，或者在第一设备配置了第一资源时，第一信息是通过第一搜索空间发送给第二设备的，因此，在第一搜索空间和第二搜索空间发生碰撞时，第二设备只需要检测第一搜索空间，就可以得到第一信息，这样，第二设备通过检测第一搜索空间就可以及时接收到寻呼消息中的紧急信息、系统消息改变等信息，避免因未接收到紧急信息造成的损失以及更新延迟造成的传输失败，从而可以最小化对第二设备的影响。
进一步地，第一设备还可以确定第二信息，该第二信息用于指示第二设备在第一资源上传输的信号的传输状态，在第一搜索空间和第二搜索空间存在资源重叠，或者在第一设备使能第二设备跳过第一资源传输时，或者通过高层信令指示第一信息在第一搜索空间中传输时，或者在第一设备配置了第一资源时，第一设备通过第一搜索空 间向第二设备发送第一信息和第二信息，因此，在第一搜索空间和第二搜索空间发生碰撞时，第二设备只需要检测第一搜索空间，就可以得到第一信息和第二信息，这样，第二设备通过检测第一搜索空间就可以及时接收到寻呼消息中的紧急信息、系统消息改变等信息，避免因未接收到紧急信息造成的损失以及更新延迟造成的传输失败，而且可以使得第二设备接收到PUR的反馈信息，避免了不必要的重传或者回退，减少了功率浪费，从而可以最小化对第二设备的影响。
其中，回退是指当PUR传输失败时，或者在第一搜索空间没有接收到PUR反馈信息时，第二设备发起随机接入或者数据早传进入连接态，以发送数据。
本申请还提出了一种通信方法，在第一搜索空间和第二搜索空间存在资源重叠，或者在第一设备使能第二设备跳过第一资源传输时，或者通过高层信令指示第一信息在第一搜索空间中传输时，或者在第一设备配置了第一资源时，第一设备还可以向第二设备发送第三信息，该第三信息用于指示第二设备在本次寻呼时机接收第一信息，或者在下一个寻呼时机接收第一信息。由于第二设备可以根据第一设备发送的第三信息选择性的接收第一信息或第二信息，从而在第一搜索空间和第二搜索空间发生碰撞时，可以通知第二设备有无第一信息或是否接收第一信息，此时可以使得第二设备及时接收紧急信息，从而最小化对第二设备的影响。
本申请还提出了一种通信方法，第一设备还可以向第二设备发送第四信息，该第四信息用于指示第二设备检测第三搜索空间和/或第四搜索空间，该第三搜索空间用于传输多播业务信道(multicast traffic channel，MTCH)，第四搜索空间用于传输多播控制信道(multicast control channel，MCCH)。
本申请还提出了一种通信方法，第二设备根据第一规则确定是检测第一搜索空间、第二搜索空间、第三搜索空间还是第四搜索空间，从而在搜索空间发生碰撞时，可以最小化对第二设备的影响。
本申请还提出了一种通信方法，第一设备还可以向第二设备发送第五信息，该第五信息用于指示第二设备是否检测第一搜索空间，从而在第一搜索空间和第二搜索空间发生碰撞时，可以最小化对第二设备的影响，其中，该第五信息包括第一搜索空间和第二搜索空间之间的重复次数。
本申请还提出了一种通信方法，第一设备还可以向第二设备发送第六信息，该第六信息用于指示第二设备是检测第一搜索空间，或者检测第二搜索空间，或者检测第一搜索空间和第二搜索空间，从而在第一搜索空间和第二搜索空间发生碰撞时，可以最小化对第二设备的影响。
本申请还提出了一种通信方法，可以将第一搜索空间和第二搜索空间配置于同一窄带，或者，第一搜索空间和第二搜索空间所在窄带相同，第二设备可以在该窄带中检测第一搜索空间和第二搜索空间，由此可以得到通过第一搜索空间传输的第一信息或第二信息，并且也可以得到通过第二搜索空间传输的第一信息或第二信息。这样，第二设备不仅可以及时接收到寻呼消息中的紧急信息、系统消息改变等信息，避免因未接收到紧急信息造成的损失以及更新延迟造成的传输失败，而且可以使得第二设备接收到PUR的反馈信息，避免了不必要的重传或者回退，减少了功率浪费。
本申请还提出了一种通信方法，第一设备通过确定第一信息，该第一信息用于指 示寻呼内容，在第一搜索空间和第二搜索空间存在资源重叠，或者在第一设备使能第二设备跳过第一资源传输时，或者通过高层信令指示第一信息在第一搜索空间中传输时，或者在第一设备配置了第一资源时，第一设备通过无线资源控制(Radio Resource Control，RRC)或媒体接入控制(Media Access Control，MAC)协议数据单元(Protocol Data Unit，PDU)向第二设备发送第一信息。由于在第一搜索空间和第二搜索空间存在资源重叠，或者在第一设备使能第二设备跳过第一资源传输时，或者通过高层信令指示第一信息在第一搜索空间中传输时，或者在第一设备配置了第一资源时，第一信息可以通过RRC或MAC PDU发送给第二设备，因此，在第一搜索空间和第二搜索空间发生碰撞时，第二设备只需要检测RRC或MAC PDU，就可以得到第一信息，这样，第二设备通过检测RRC或MAC PDU就可以及时接收到寻呼消息中的紧急信息、系统消息改变等信息，避免因未接收到紧急信息造成的损失以及更新延迟造成的传输失败，从而可以最小化对第二设备的影响。
下面，通过具体实施例对本申请的技术方案进行详细说明。需要说明的是，下面这几个具体的实施例可以相互结合，对于相同或相似的概念或过程可能在某些实施例中不再赘述。
图2为本申请通信方法的一种信令交互图。本实施例以通信系统中的第一设备和第二设备之间的信息交互进行说明。在上述图1所示系统架构的基础上，如图2所示，在本实施例中，该通信方法可以包括如下步骤：
步骤201：第一设备确定第一信息。
其中，第一信息用于指示寻呼内容。
示例性的，第一信息可以包括如下信息中的至少一种：寻呼指示信息、系统消息变更通知(system Info Modification)信息(indication of a BCCH modification other than SIB10,SIB11,SIB12and SIB14)、地震和海啸警告系统(earthquake and tsunami warning system，etws)通知信息(indication of an ETWS primary notification and/or ETWS secondary notification)、商业移动警报服务(commercial mobile alert service，cmas)指示信息(indication of a CMAS notification)、系统架构演化临时移动站标识符(System Architecture Evolution Temporary Mobile Station Identifier，S-TMSI)、国际移动用户身份(International Mobile Subscriber Identity，IMSI)、无线网络临时标识(Radio Network Temporary Identifier，RNTI)和接入类型(accessType)信息(It indicates whether Paging is originated due to the PDU sessions from the non-3GPP access when E-UTRA is connected to 5GC)。
其中，寻呼指示信息用于指示第二设备的寻呼状态，该寻呼状态可以包括第二设备被寻呼，或者也可以包括第二设备没有被寻呼。另外，寻呼指示信息也可以称为无线资源控制(Radio Resource Control，RRC)连接指示信息，即用于指示第二设备是否进入RRC连接态，或者还可以称为RRC连接完成指示信息，即用于指示RRC建立连接完成。进一步地，该寻呼指示信息还可以用于指示第二设备是否发起随机接入或进行数据早传(Early data transmission)等。
RNTI包括第一资源RNTI或小区RNTI(cell-RNTI，C-RNTI)，可以理解的是，第一信息中携带该RNTI可以指示第二设备进入了连接态，这是一种隐式指示用于进入 连接态的方法，由于该RNTI是连接态时第二设备必要的配置，使用该隐式方式可以减少信令开销。示例性的，第一资源可以为PUR资源。
另外，上述的系统消息变更通知信息、地震和海啸警告系统通知信息、商业移动警报服务指示信息等信息通过下行控制信息发送给第二设备。寻呼指示信息可以通过高层信令发送给第二设备。寻呼指示信息包括小区RNTI(cell-RNTI，C-RNTI)或第一RNTI，用于指示第二设备进入连接态。
在一种可能的实现方式中，可以用1比特信息表示第一信息，例如：若第一信息为“0”时，可以用于指示第二设备没有被寻呼或不进入连接状态或保持空闲状态，若第一信息为“1”，则用于指示第二设备被寻呼或指示第二设备进入连接态；或者，若第一信息为“0”时，用于指示系统消息没有变更，若第一信息为“1”，则用于指示系统消息发生了变更；或者，若第一信息为“0”时，可以用于指示不存在地震和海啸警告信息，若第一信息为“1”，则用于指示存在地震和海啸警告信息；或者，若第一信息为“0”时，可以用于指示不存在商业移动警报服务指示，若第一信息为“1”，则用于指示存在商业移动警报服务指示；或者，若第一信息为“0”时，可以用于指示接入类型为非第三代合作伙伴计划(non 3rd Generation Partnership Project，non 3GPP)接入，若第一信息为“1”，则用于指示接入类型为3GPP接入等。
在另一种可能的实现方式中，也可以用比特位图的方式表示第一信息，例如，用1比特来指示寻呼指示信息，1比特来指示系统消息变更通知信息，1比特来指示etws通知信息，1比特来指示cmas指示信息，1比特来指示接入类型。例如：若第一信息为“11001”，则表示第二设备被寻呼或第二设备进入连接态、系统消息发生了变更、不存在etws通知信息、不存在cmas指示且接入类型为3GPP接入。
进一步地，第一设备还可以确定第二信息，其中，该第二信息用于指示第二设备在第一资源上传输的信号的传输状态。
其中，第一资源可以为PUR资源，第二设备在第一资源上传输的信号的传输状态，可以理解为第二设备在PUR资源上传输的信号的传输状态，该传输状态包括传输成功和/或传输失败，也可以理解为确认应答ACK(Acknowledge)和/或否定应答NACK(Negative Acknowledgment)。
在一种可能的实现方式中，第二信息包括第一指示信息和/或第二指示信息，该第一指示信息用于指示PUR传输是否成功，该第二指示信息用于指示调度PUR重传。
具体地，第二信息中可以仅包括第一指示信息，也可以仅包括第二指示信息，还可以包括第一指示信息和第二指示信息。其中，第一指示信息用于指示PUR传输是否成功，第二指示信息用于指示调度PUR重传或指示PUR重传。
其中，PUR重传可以指，在预配置上行链路资源中或在部分预配置上行链路资源中进行重传，即不需要动态调度信息(如DCI)调度，而是通过预配置上行链路资源进行重传，但是相应的预配置资源的配置信息可以通过动态调度信息进行重配或更新。
调度PUR重传是指第二设备根据第一设备的动态调度信息(如DCI)的调度信息进行重传。
示例性的，第二信息还可以包括第一搜索空间和第二搜索空间的重复次数、功率信息和时间提前量(Timing Advance，TA)信息中的至少一个。
进一步地，第一信息或第二信息包含于下行控制信息(Downlink Control Information，DCI)中。
在一种可能的实现方式中，若第一设备确定第一信息，则该第一信息可以包含于DCI中。
值得注意的是，该第一信息还可以包含于由第一搜索空间中的DCI调度的数据中，其中，若第一信息包含于由第一搜索空间中的DCI调度的数据中时，第一信息可以包含于RRC消息或媒体接入控制(Media Access Control，MAC)协议数据单元(Protocol Data Unit，PDU)中。需要进行说明的是，第一信息包含于由第一搜索空间中的DCI调度的数据中，也可以理解为第一信息包含于由第一搜索空间中的DCI调度的物理下行共享信道(Physical Downlink Shared Channel，PDSCH)中。其中，第一搜索空间中的DCI调度也可以理解为由第一RNTI加扰的DCI调度的下行共享信道。
在另一种可能的实现方式中，若第一设备还确定第二信息，则该第二信息也可以包含于DCI中。
值得注意的是，在第二信息不通过第一搜索空间传输时，该第二信息还可以包含于由第一搜索空间中的DCI调度的数据中，其中，若第二信息包含于由第一搜索空间中的DCI调度的数据中时，第二信息可以包含于RRC消息或MAC PDU中。
也就是说，在第一设备确定第一信息和第二信息时，可以包括如下四种情况：第一信息包含于DCI中，第二信息也包含于DCI中，或者，第一信息包含于DCI中，第二信息包含于由第一搜索空间中的DCI调度的数据中，或者，第一信息包含于由第一搜索空间中的DCI调度的数据中，第二信息包含于DCI中，或者，第一信息包含于由第一搜索空间中的DCI调度的数据中，第二信息也包含于由第一搜索空间中的DCI调度的数据中。
其中，与第一信息类似，第二信息包含于由第一搜索空间中的DCI调度的数据中，也可以理解为第二信息包含于由第一搜索空间中的DCI调度的PDSCH中。
另外，在本申请实施例中，调度下行数据的DCI中或该DCI调度的下行数据中还包括混合自动重传请求(Hybrid Automatic Repeat reQuest，HARQ)-确认(Acknowledgement，ACK)(或物理上行链路控制信道(Physical Uplink Control Channel，PUCCH))的配置信息。该配置信息包括以下信息的一种或多种：时频资源(也可以通过两级配置，高层配置资源，此处配置资源索引)、反馈时间(延时)、功率控制信息和重复次数。
示例性的，该DCI可以由第一资源RNTI加扰，也可以由第二RNTI加扰，其中，第一资源RNTI可以为系统信息无线网络临时标识(system information Radio Network Temporary Identifier，SI-RNTI)，第二RNTI可以是paging RNTI。第二设备通过检测DCI，如果检测出DCI是由第一资源RNTI加扰的，则第二设备将不进入连接态；如果DCI是由第二RNTI加扰的，则第二设备将进入连接态。需要进行说明的是，此时，可以不用确定第一信息，即可直接根据DCI的加扰方式，确定第二设备是否进入连接态。
进一步地，在一种可能的实现方式中，DCI中、RRC消息中或MAC PDU中还可以包含第三指示信息，该第三指示信息可以用于指示在DCI中、RRC消息中或MAC  PDU中是否包含有第一信息，或者是否包含有第二信息，或者是否包含第一信息和第二信息。示例性的，若第一设备确定第一信息，则可以用1比特信息来表示第三指示信息，例如，若第三指示信息位于DCI中，且第三指示信息的值为“0”时，表示DCI中不包含第一信息，或者，若DCI中的第三指示信息的值为“1”时，表示DCI中包含第一信息，或者，若DCI中的第三指示信息的值为“1”时，表示DCI中包含第一信息和第二信息。当然，也可以是第三指示信息的值为“0”时，表示DCI中包含第一信息，或者，DCI中的第三指示信息的值为“1”时，表示DCI中不包含第一信息，或者，DCI中的第三指示信息的值为“0”时，表示DCI中包含第一信息和第二信息。
若第一设备确定第一信息和第二信息，则可以用2比特信息来表示第三指示信息，例如，若第三指示信息位于DCI中，且第三指示信息的值为“00”时，表示DCI中不包含第一信息，且不包含第二信息，若DCI中的第三指示信息的值为“01”时，表示DCI中不包含第一信息，但是包含第二信息，若DCI中的第三指示信息的值为“10”时，表示DCI中包含第一信息，但是不包含第二信息，若DCI中的第三指示信息的值为“11”时，表示DCI中包含第一信息，且包含第二信息。当然，也可以用其他方式表示DCI中是否包含第一信息或是否包含第二信息，对于具体的表示方式，本申请实施例在此不做限制。
对于第三指示信息位于RRC消息中和/或MAC PDU中时，第三指示信息的指示方式与位于DCI中类似，此处不再赘述。
值得注意的是，PUR仅是一种示例性命名，其实质是第一设备通过配置第一资源，第二设备可以在不需要第一设备动态调度或下行控制信息调度的情况下在第一资源上进行上行信息的传输，该资源也可以命名为其他名称，如配置授权资源。应理解，若该配置授权资源也可以实现本申请实施例中的第一资源所实现的功能，也可以将配置授权资源理解为本申请实施例中的第一资源。为了描述方便，本申请实施例中将第一资源统一称为预配置上行链路资源。
预配置资源传输，可以指第二设备在预配置上行链路资源按照预先规定的参数进行数据传输。本申请实施例中“预配置资源传输”也可以称为“预配置传输方式”、“免调度传输”、“预配置资源传输”、“预配置资源免调度传输”等。应理解，本申请实施例中“预配置资源传输”仅是一种示例性说明，在实际应用中，也可以将“预配置资源传输”命名为其他名称，若该其他名称也可以实现本申请实施中“预配置资源传输”的功能，都可以理解为按照预配置资源传输的方式进行上行信号传输。为了描述方便，本申请实施例中将该传输方式统一称为预配置资源传输。
步骤202：在第一搜索空间和第二搜索空间存在资源重叠，或者在第一设备使能第二设备跳过第一资源传输时，第一设备通过第一搜索空间向第二设备发送第一信息。
其中，在第一搜索空间和第二搜索空间存在资源重叠，或者在第一设备使能第二设备跳过第一资源传输时，或者通过高层信令指示第一信息在第一搜索空间中传输时，或者在第一设备配置了第一资源时，或者第一设备通过指示信息指示第二设备不检测第二搜索空间时，第一设备通过第一搜索空间向第二设备发送第一信息。
示例性的，上述第一搜索空间用于或包含传输第一设备反馈第一资源传输的状态信息和/或调度重传的下行控制信息(也可以称为包含该下行控制信息的资源)，第二 搜索空间用于或包含传输调度寻呼消息的下行控制信息。其中，搜索空间是可能的传输下行控制信息的资源的集合。
具体地，第一搜索空间是指第一资源搜索空间，例如可以为PUR搜索空间(PUR SS)，其可以仅用于传输第一设备反馈第一资源传输的状态信息，也可以仅用于传输调度重传的下行控制信息，还可以同时传输第一设备反馈第一资源传输的状态信息和调度重传的下行控制信息。
另外，第二搜索空间例如可以为Type1-MPDCCH common search space(Type1SS)。
其中，第一搜索空间和第二搜索空间存在资源重叠，可以理解为第一搜索空间的至少一个第一时间单元属于第二搜索空间，也即第一搜索空间中的至少一个时间单位与第二搜索空间重叠。可选的，第一时间单元为帧(frame)，或者为子帧(subframe)，或者为时隙(slot)，或者为符号(symbol)。
第一设备使能第二设备跳过第一资源传输，可以理解为第一设备配置第二设备在有数据传输时，使用第一资源进行该数据的传输，在没有数据传输时，跳过该第一资源，也即不使用该第一资源，也可以理解为第二设备可以不使用第一资源传输信号。
基于此，在第一设备确定第一信息，且在第一搜索空间和第二搜索空间存在资源重叠，或者在第一设备使能第二设备跳过第一资源传输时，或者通过高层信令指示第一信息在第一搜索空间中传输时，或者第一设备通过指示信息指示第二设备不检测第二搜索空间时，或者在第一设备配置了第一资源时，第一设备将通过第一搜索空间向第二设备发送第一信息。
或者，在第一设备确定第一信息和第二信息，且在第一搜索空间和第二搜索空间存在资源重叠，或者在第一设备使能第二设备跳过第一资源传输时，或者通过高层信令指示第一信息和第二信息在第一搜索空间中传输时，或者第一设备通过指示信息指示第二设备不检测第二搜索空间时，或者在第一设备配置了第一资源时，第一设备将通过第一搜索空间向第二设备发送第一信息和第二信息。
其中，通过第一搜索空间向第二设备发送第一信息，可以理解为通过第一RNTI加扰的DCI向第二设备发送第一信息，也可以理解为通过第一搜索空间中的DCI向第二设备发送第一信息，还可以理解为第二设备将不会检测第二搜索空间。
对于通过第一搜索空间向第二设备发送第一信息和第二信息的情况，与通过第一搜索空间向第二设备发送第一信息的情况类似，此处不再赘述。
由于第一设备可以通过第一搜索空间向第二设备发送第一信息，因此，在第一搜索空间和第二搜索空间存在资源重叠，或者在第一设备使能第二设备跳过第一资源传输时，或者在第一设备配置了第一资源时，第一信息是通过第一搜索空间发送给第二设备的，因此，在第一搜索空间和第二搜索空间发生碰撞时，第二设备只需要检测第一搜索空间，就可以得到第一信息，这样，第二设备可以及时接收到寻呼消息中的紧急信息、系统消息改变等信息，避免因未接收到紧急信息造成的损失以及更新延迟造成的传输失败。
另外，第一设备可以通过第一搜索空间向第二设备发送第一信息和第二信息，在第一搜索空间和第二搜索空间存在资源重叠，或者在第一设备使能第二设备跳过第一资源传输时，或者通过高层信令指示第一信息在第一搜索空间中传输时，或者在第一 设备配置了第一资源时，第一设备通过第一搜索空间向第二设备发送第一信息和第二信息，因此，在第一搜索空间和第二搜索空间发生碰撞时，第二设备只需要检测第一搜索空间，就可以得到第一信息和第二信息，这样，第二设备通过检测第一搜索空间就可以及时接收到寻呼消息中的紧急信息、系统消息改变等信息，避免因未接收到紧急信息造成的损失以及更新延迟造成的传输失败，而且可以使得第二设备接收到PUR的反馈信息，避免了不必要的重传或者回退，减少了功率浪费，从而可以最小化对第二设备的影响。
在一种可能的实现方式中，第一搜索空间和第二搜索空间配置于同一窄带，或者，第一搜索空间和第二搜索空间所在窄带相同。具体地，第一设备可以将第一搜索空间和第二搜索空间配置在同一窄带中，这样，第二设备可以在该窄带中检测第一搜索空间和第二搜索空间。第二设备可以及时接收到寻呼消息中的紧急信息、系统消息改变等信息，避免因未接收到紧急信息造成的损失以及更新延迟造成的传输失败，而且可以使得第二设备接收到PUR的反馈信息，避免了不必要的重传或者回退，减少了功率浪费，从而可以最小化对第二设备的影响。
进一步地，可以理解的是，若第一信息和第二信息通过不同的搜索空间传输时，例如第一信息通过第一搜索空间传输，第二信息通过第二搜索空间传输，或者第一信息通过第二搜索空间传输，第二信息通过第一搜索空间传输时，将第一搜索空间和第二搜索空间配置在同一窄带中后，第二设备可以在该窄带中检测第一搜索空间和第二搜索空间，由此可以得到通过第一搜索空间传输的第一信息或第二信息，并且也可以得到通过第二搜索空间传输的第一信息或第二信息。这样，第二设备不仅可以及时接收到寻呼消息中的紧急信息、系统消息改变等信息，避免因未接收到紧急信息造成的损失以及更新延迟造成的传输失败，而且可以使得第二设备接收到PUR的反馈信息，避免了不必要的重传或者回退，减少了功率浪费。
步骤203：第二设备根据第一信息，确定是否进入连接态。
具体地，第二设备在接收到第一设备发送的第一信息之后，将会确定第二设备是否进入连接态以及其他指示信息。
另外，第二设备还可以根据第一信息确定以下消息中的一种或多种：确定是否发起随机接入，确定是否进行数据早传(Early data transmission)，确定是否有紧急信息，确定是否存在系统消息变更等。
进一步地，若第一设备通过第一搜索空间向第二设备发送第一信息和第二信息，则第二设备将根据第一信息确定第二设备是否进入连接态，根据第二信息确定在第一资源上传输的信号的传输状态。
本申请实施例提供的通信方法，第一设备通过确定第一信息，该第一信息用于指示寻呼内容，在第一搜索空间和第二搜索空间存在资源重叠，或者在第一设备使能第二设备跳过第一资源传输时，或者在第一设备配置了第一资源时，第一设备通过第一搜索空间向第二设备发送第一信息。由于在第一搜索空间和第二搜索空间存在资源重叠，或者在第一设备使能第二设备跳过第一资源传输时，或者通过高层信令指示第一信息在第一搜索空间中传输时，或者在第一设备配置了第一资源时，第一信息是通过第一搜索空间发送给第二设备的，因此，在第一搜索空间和第二搜索空间发生碰撞时， 第二设备只需要检测第一搜索空间，就可以得到第一信息，这样，第二设备可以及时接收到寻呼消息中的紧急信息、系统消息改变等信息，避免因未接收到紧急信息造成的损失以及更新延迟造成的传输失败，从而可以最小化对第二设备的影响。
进一步地，第一设备还可以确定第一信息和第二信息，该第二信息用于指示第二设备在第一资源上传输的信号的传输状态，在第一搜索空间和第二搜索空间存在资源重叠，或者在第一设备使能第二设备跳过第一资源传输时，或者通过高层信令指示第一信息在第一搜索空间中传输时，或者在第一设备配置了第一资源时，第一设备通过第一搜索空间向第二设备发送第一信息和第二信息，因此，在第一搜索空间和第二搜索空间发生碰撞时，第二设备只需要检测第一搜索空间，就可以得到第一信息和第二信息，这样，第二设备通过检测第一搜索空间就可以及时接收到寻呼消息中的紧急信息、系统消息改变等信息，避免因未接收到紧急信息造成的损失以及更新延迟造成的传输失败，而且可以使得第二设备接收到PUR的反馈信息，避免了不必要的重传或者回退，减少了功率浪费，从而可以最小化对第二设备的影响。
在一种可能的实现方式中，在第一搜索空间和第二搜索空间存在资源重叠，或者在第一设备使能第二设备跳过第一资源传输时，或者通过高层信令指示第一信息在第一搜索空间中传输时，或者在第一设备配置了第一资源时，第一设备还可以向第二设备发送第三信息，该第三信息用于指示第二设备在本次寻呼时机接收第一信息，或者在下一个寻呼时机接收第一信息。
示例性的，该第三信息可以包含于DCI中。具体可以用1比特信息来表示第三信息，例如：若第三信息的值为“0”，则表示第二设备在本次寻呼时机(paging occasion)接收第一信息，若第三信息的值为“1”，则表示第二设备将在下一个寻呼时机接收第一信息。其中，若第三信息指示第二设备在下一个寻呼时机接收第一信息，那么就意味着第二设备将会在本次接收第二信息或者是第一信息不在第一搜索空间中传输。
由于第一设备可以通过第三信息指示第二设备在本次寻呼时机接收第一信息，或者在下一个寻呼时机接收第一信息，使得第二设备可以根据第一设备的指示选择性的接收第一信息或第二信息，从而在第一搜索空间和第二搜索空间发生碰撞时，可以通知第二设备有无第一信息或是否接收第一信息，此时可以使得第二设备及时接收紧急信息，从而最小化对第二设备的影响。
在另一种可能的实现方式中，第一设备还可以向第二设备发送第四信息，该第四信息用于指示第二设备检测第三搜索空间和/或第四搜索空间，该第三搜索空间用于传输多播业务信道(multicast traffic channel，MTCH)，第四搜索空间用于传输多播控制信道(multicast control channel，MCCH)。
具体地，第一设备还可以向第二设备发送第四信息，以通过第四信息指示第二设备是仅检测第三搜索空间，还是仅检测第四搜索空间，或者同时检测第三搜索空间和第四搜索空间。其中，第三搜索空间例如可以为Type2A-MPDCCH common search space(Type2A SS)，第四搜索空间例如可以为Type1A-MPDCCH common search space(Type1A SS)。
进一步地，在一种可能的实现方式中，第一设备可以配置第一规则，并将该第一规则发送给第二设备。在另一种可能的实现方式中，该第一规则也可以是预定义的， 第二设备可以根据该第一规则确定第二设备是检测第一搜索空间、第二搜索空间、第三搜索空间还是第四搜索空间。其中，该第一规则用于表示第一搜索空间、第二搜索空间、第三搜索空间和第四搜索空间之间的优先级。
示例性的，上述优先级从高到低的顺序依次为：第二搜索空间、第一搜索空间、第四搜索空间和第三搜索空间。
具体地，当第一设备使能第二设备跳过第一资源传输时，且第二设备在第一资源上没有信息传输时，第二设备根据第一规则检测第一搜索空间或其他搜索空间。举例来说，若第一规则中各搜索空间之间的优先级从高到低的顺序依次为：第二搜索空间(Type1搜索空间)、第一搜索空间(PUR搜索空间)、第四搜索空间(Type1A搜索空间)和第三搜索空间(Type2A搜索空间)。其中，由于Type1搜索空间的优先级高于PUR搜索空间，在组成PUR的第一时间单元或组成PUR搜索空间的第一时间单元(如子帧、时隙或符号)包括组成Type1搜索空间的第二时间单元，也就是说，当Type1搜索空间和PUR搜索空间在时间资源上有重叠时，根据前述的第一规则，那么第二设备将检测第二搜索空间(Type1搜索空间)。对于确定是否检测其他的搜索空间的方式，与确定是否检测Type1搜索空间和PUR搜索空间的方式类似，此处不再赘述。
由于第一设备预先定义或者预配置第一规则，该第一规则表示了第一搜索空间、第二搜索空间、第三搜索空间和第四搜索空间之间的优先级，使得第二设备可以根据该第一规则确定检测哪一个搜索空间，从而在第一搜索空间和第二搜索空间发生碰撞时，可以最小化对第二设备的影响。
另外，当第一设备使能第二设备跳过PUR资源传输，且PUR中没有数据传输时，第二设备不必检测第一搜索空间，此时定义的优先级规则成立，这样第二设备既没有错过paging，又不会因为没有接收第一搜索空间而回退到连接态或造成PUR重传，由此可以节省第二设备的功耗。
在又一种可能的实现方式中，第一设备还可以向第二设备发送第五信息，该第五信息用于指示第二设备是否检测第一搜索空间或是否检测第二搜索空间。
示例性的，该第五信息包括第一搜索空间和第二搜索空间之间的重复次数。也即，第二设备可以根据第一搜索空间和第二搜索空间之间的重复次数，确定是否检测第一搜索空间或是否检测第二搜索空间。
下面，以根据第一搜索空间和第二搜索空间之间的重复次数确定是否检测第一搜索空间为例进行说明，对于确定是否检测第二搜索空间的方式，与是否检测第一搜索空间的方式类似，此处不再赘述。具体地，第一搜索空间和第二搜索空间之间的重复次数，可以理解为由第一RNTI加扰的DCI(物理下行控制信道(Physical Downlink Control Channel，PDCCH))的重复次数和由第二RNTI加扰的DCI(PDCCH)的重复次数，也可以理解为第一搜索空间重复的第一时间单元和第二搜索空间重复的第一时间单元的和，其中，第一时间单元可以为帧(frame)，或者为子帧(subframe)，或者为时隙(slot)，或者为符号(symbol)。当第一搜索空间和第二搜索空间之间的重复次数大于第一阈值，也即第一搜索空间重复的第一时间单元和第二搜索空间重复的第一时间单元的和大于第一阈值时，说明只能传输一个搜索空间，此时，第二设备将不 检测第一搜索空间，其中，第一阈值可以为PUR周期的长度，或PUR周期中有效子帧数，或PUR周期中窄带低功耗(Bandwidth reduced Low complexity，BL)/覆盖增强(Coverage Enhancement，CE)子帧数。示例性的，当第一搜索空间和第二搜索空间之间的重复次数大于第一阈值时，第二设备将不检测第二搜索空间，且第一设备可以通过第一搜索空间向第二设备发送第一信息，此时，第二设备只需要检测第一搜索空间，就可以得到第一信息，这样，第二设备通过检测第一搜索空间就可以及时接收到寻呼消息中的紧急信息、系统消息改变等信息，避免因未接收到紧急信息造成的损失以及更新延迟造成的传输失败，从而可以最小化对第二设备的影响。
当第一搜索空间和第二搜索空间之间的重复次数不大于第一阈值，也即第一搜索空间重复的第一时间单元和第二搜索空间重复的第一时间单元的和不大于第一阈值时，说明可以传输两个搜索空间，此时，第二设备会先检测第二搜索空间，并在接收完寻呼消息(paging)的控制信息，或paging信息的最后一个第一时间单元后的第k个第一时间单元开始检测第一搜索空间，其中，k为大于或等于零的整数。或者，第二设备会先检测第二搜索空间，并且第一设备会向第二设备指示一个偏移值，第二设备根据这个偏移值和/或paging的重复次数以及起始位置确定第一搜索空间的起始位置。
值得注意的是，当第一搜索空间和第二搜索空间之间的重复次数不大于第一阈值时，第二设备也可以先检测第一搜索空间，并在接收完寻呼消息(paging)的控制信息，或paging信息的最后一个第一时间单元后的第n个第一时间单元开始检测第二搜索空间，其中，n为大于或等于零的整数。或者第二设备会先检测第一搜索空间，并且第一设备会向第二设备指示一个偏移值，第二设备根据这个偏移值和/或paging的重复次数以及起始位置确定第二搜索空间的起始位置。
以第一搜索空间为PUR搜索空间(PUR SS)，第二搜索空间为为Type1-MPDCCH common search space(Type1SS)，第一时间单元为子帧为例进行说明。图3为第二设备是否检测PUR搜索空间的示意图，如图3所示，当PUR SS重复的子帧数和Type1SS重复的子帧数的和大于第一阈值时，第二设备将不检测PUR SS。当PUR SS重复的子帧数和Type1SS重复的子帧数的和不大于第一阈值时，第二设备在接收完寻呼消息(paging)的控制信息，或paging信息的最后一个子帧后的第k个子帧开始检测PUR SS。
由于第一设备通过向第二设备发送第五信息，以指示第二设备是否检测第一搜索空间，从而在第一搜索空间和第二搜索空间发生碰撞时，可以最小化对第二设备的影响。
另外，第二设备根据paging和第一搜索空间的周期或持续长度确定是否检测第一搜索空间，可以最大限度的避免PUR重传，提升灵活性。
在又一种可能的实现方式中，第一设备还可以向第二设备发送第六信息，该第六信息用于指示第二设备是检测第一搜索空间，或者检测第二搜索空间，或者检测第一搜索空间和第二搜索空间。
具体地，第一设备可以通过高层信令，向第二设备发送第六信息，第二设备根据该第六信息确定是检测第一搜索空间，还是检测第二搜索空间。示例性的，可以通过1比特信息表示第六信息，例如若第六信息的值为“0”，则可以表示第二设备检测第 一搜索空间，若第六信息的值为“1”，则表示第二设备检测第二搜索空间。
在本申请实施例中，高层信令可以是指高层协议层发出的信令，高层协议层为物理层以上的至少一个协议层。其中，高层协议层具体可以包括以下协议层中的至少一个：媒体接入控制(Medium Access Control，MAC)层、无线链路控制(Radio Link Control，RLC)层、分组数据汇聚协议(Packet Data Convergence Protocol，PDCP)层、无线资源控制(radio resource control，RRC)层和非接入层(non-access stratum，NAS)等。
其中，若第一设备通过第六信息指示第二设备检测第一搜索空间，则说明第一信息是通过第一搜索空间进行传输的，这样，第二设备通过检测第一搜索空间就可以及时接收到寻呼消息中的紧急信息、系统消息改变等信息，避免因未接收到紧急信息造成的损失以及更新延迟造成的传输失败，从而可以最小化对第二设备的影响。
由于第一设备通过向第二设备发送第六信息，以指示第二设备是检测第一搜索空间，还是检测第二搜索空间，从而在第一搜索空间和第二搜索空间发生碰撞时，可以最小化对第二设备的影响。
示例性的，当终端设备在PUR传输之后，第二设备需要检测相应的搜索空间，并接收第一设备发送的反馈信息和调度信息，以检测PUR传输是否成功。由于PUR可能成功传输也可能没有成功传输，若成功传输，理论上不需要继续检测相应搜索空间，以达到节电的目的。而如果没有成功传输，则PUR重传，那么重传后第二设备仍然需要监测相应的搜索空间，并接收第一设备发送的下行反馈和控制信息，因此如何确定搜索空间的起始位置以及搜索时机是十分重要的。
其中，搜索空间(下行控制信道(MTCPhysical Downlink Control Channel，MPDCCH))的起始位置是根据如下至少一种信息确定的：PUR的起始(终止)时间、频域位置、PUR的起始位置和重复次数，如，起始位置为k0子帧后的第(a+n+b)个连续BL/CE子帧。其中a，b，n为正整数，a和b为预定义或通过高层配置的，n为PUR的重复次数(也可以称为PUR的时域子帧个数)，在一种可能的实现方式中，a为根据PUR的起始位置确定的。
由于上述通过隐式确定的方式，来确定搜索空间的起始位置，可以减少信令开销。
示例性的，第一设备为第二设备配置多个时间窗(time window)，或者也可以称为配置多段时间，或者配置多个搜索时间起始位置，或者配置多个间隔，或者多个搜索空间，其中，该间隔用来确定搜索空间的起点或者多个时间长度。第二设备在第一搜索空间接收第七信息，该第七信息用于指示否定应答(Negative Acknowledgement，NACK)，或者，第二设备接收否定应答(NACK)，第二设备根据是否重传或新数据调度或收到的否定应答(Negative Acknowledgement，NACK)确定检测的时间窗个数或者起始位置或搜索空间。第二设备在第一搜索空间接收第八信息，该第八信息用于指示确认应答(Acknowledge，ACK)或第二设备接收确认应答，第二设备根据接收到的确认应答确定不检测或跳过第二搜索空间，第二搜索空间包括一个或多个搜索空间，示例性的，第二搜索空间不包括第一搜索空间。或者，第二设备根据接收到的确认应答确定不检测或跳过第一时间内的第二搜索空间，其中，第一时间包括PUR周期，第二搜索空间包括一个或多个搜索空间，示例性的，第二搜索空间不包括第一搜索空间。
例如当第二设备在PUR传输之后，会在传输结束后的一段时间开始检测搜索空间，接收下行控制信息，用以确定PUR传输是否成功。图4为PUR传输成功后检测搜索空间的示意图，如图4所示，当PUR传输成功时，通常只检测第一个搜索空间，后续将不需要继续检测搜索空间。
图5为PUR传输失败后检测搜索空间的示意图，如图5所示，当PUR传输失败时，在检测第一个搜索空间后，还将继续检测后一个PUR搜索空间。
当调度重传N次时，或接收到N个NACK时，或在第一搜索空间没有收到任何信息时，第二设备会发起随机接入或提前数据传输(early data transmission，EDT)。例如，N＝1，即接收到一个NACK时，发起随机接入或EDT。
另外，上述的多个搜索空间的周期是相同的，而且重复次数是相同的。
由于在PUR传输成功后，通常只检测第一个搜索空间，后续将不需要继续检测搜索空间，在PUR传输失败后，在检测第一个搜索空间后，还将继续检测后一个PUR搜索空间，即在不同情况下对搜索空间进行扩展，既可以达到节电的目的，也可以使得第二设备不丢失下行控制信息。
示例性的，对于周期性业务，为了降低资源开销，降低数据传输时延，且达到节能的目的，可在预先定义好的资源上传输业务，也就是不需要DCI动态调度，第二设备可以在预先配置的资源上传输上行信息，其中，上行信息可以包括数据、控制信息和参考信号中的一种或多种，对于上行信息的具体形式，此处不做具体限定。另外，需要进行说明的是，预先配置的上行资源(preconfigured uplink resource,PUR)仅是一种示例性命名，其实质是第一设备通过配置第一资源，第二设备可以在不需要第一设备动态调度或下行控制信息调度的情况下在第一资源上进行上行信息的传输，该资源也可以命名为其他名称，如配置授权资源，应理解，若该配置授权资源也可以实现本申请实施例中的第一资源所实现的功能，也可以将配置授权资源理解为本申请实施例中的第一资源。为了描述方便，本申请实施例中将第一资源统一称为预配置资源。
当第二设备配置了第一资源，第二设备发起随机接入(RACH)或通过EDT传输数据，第一设备和/或第二设备释放第一资源，或者可以理解的是，使用第一资源传输信息意为使用该第一资源进行如下至少一个信息的传输：数据、控制信息和参考信令，也可以理解为激活或使能第一资源，或者理解为指示第一资源为激活状态或使能状态；不使用第一资源传输信息意为不使用该第一资源进行如下至少一个信息的传输：数据、控制信息和参考信令，也可以理解为去激活或去使能第一资源，或者理解为指示第一资源为去激活状态或去使能状态。
