背景技术
在进行非授权频谱上的数据传输时，通常采用非授权频段上的LBT(Listen Before Talk，先听后说)的信道接入(Channel Access)机制。然而在高频频率范围内，由于高频信道衰减较大，往往采用no-LBT的信道接入机制进行数据传输。此种情况下，则极易发生发射端几乎连续占用信道的情况。这样一来，势必导致单一节点几乎连续占用信道，从而对其他临近节点造成持续干扰等影响。

具体实施方式
下面详细描述本公开的实施例，所述实施例的示例在附图中示出，其中自始至终相同或类似的标号表示相同或类似的元件或具有相同或类似功能的元件。下面通过参考附图描述的实施例是示例性的，旨在用于解释本公开，而不能理解为对本公开的限制。
图1为本公开实施例提供的一种数据传输方法的流程示意图，适用于非授权频段上无先听后说的信道接入场景。如图1所示，该数据传输方法包括以下步骤：
步骤101，响应于当前占用的第一信道的占用时长到达第一信道的占用最大时长MCOT，释放第一信道。
需要说明的是，在非授权频谱上，发送端在占用信道发送数据之前，通常需要对信道进行监听，即进行CCA(Clear Channel Assessment，空闲信道评估)。在发送端进行CCA后，若识别信道空闲，则可以占用信道发送数据。其中，其占用信道的MCOT(Maximum Channel Occupy Time，最大时长)由协议约定或者基站配置/指示；若识别信道非空闲，则不能占用信道。前述过程通常被称为非授权频段上的LBT(Listen Before Talk，先听后说)的信道接入(Channel Access)机制。
现有技术中，针对非授权频段上先听后说的信道接入场景，即在使用LBT的情况下，若发射端的两次数据发送之间的Gap(间隔)小于预设时长，则可以认为前述两次数据发送 属于同一次传输，进而可以共享同一个COT(占用时长)。其中，预设时长可以为16us、25us等。此外，当发射端占用信道MCOT的时长后，需要结束发送。
举例而言，发射端设置的MCOT为6ms，发射端在开始占用信道后，连续发送数据并持续了4ms，然后暂停发送，且暂停的Gap时长为T。进一步地,发射端可以开始进行下一次发送。此种情况下，若T小于或者等于16us，则可以认为这一次传输跟暂停之前的传输是属于同一次传输，发射端不需要进行LBT,可以直接开始传输，传输的时长最大可持续2ms-T，即两次传输的信道占用时长是共享的。若T大于16us，则可以认为这一次传输与暂停之前的传输不属于同一次传输，而是一次新的传输，进而也需要重新进行LBT。
在高频频率范围内，由于高频信道衰减较大，即使发送端点之间距离较近，其相互之间的干扰也可能比较小。此种情况下，通常采用no-LBT(无先听后说)的信道接入机制。也就是说，在高频频率范围内进行数据传输时，发射端在发送数据之前可以不需要进行LBT，直接发送数据。
然而针对非授权频段上无先听后说的信道接入场景，即采用no-LBT信道接入机制，此种情况下，则极易发生发射端几乎连续占用信道的情况。这样一来，势必导致单一节点几乎连续占用信道，从而对其他临近节点造成持续干扰等影响。此外，当发射端占用信道MCOT的时长后，需要结束发送。而由于采用no-LBT机制，发射端可以立即开始下一次发送，也导致了发送端连续占用信道的情况。
举例而言，若采用16us的传输间隔，在MCOT尚未结束时，发射端只需要中断发送超过16us，即在120kHz子载波约为2个符号的时长，即可以再一次重新占用信道MCOT的时长。
由此，针对前述问题，本公开可以在MCOT结束后，响应于当前占用的第一信道的占用时长到述第一信道的占用最大时长MCOT，释放第一信道。
步骤102，响应于数据传输指令，获取数据传输起始时刻与第一信道的释放时刻之间的第一时间间隔。
其中，第一时间间隔，指的是两次相邻的发送之间的Gap。
举例而言，响应于数据传输指令，获取数据传输起始时刻与第一信道的释放时刻之间的第一时间间隔，并标记为△t 1。
步骤103，响应于第一时间间隔到达第一预设时长，占用第二信道进行数据传输。
本公开实施例中，可以在确保两次相邻的发送之间的第一时间间隔达到第一预设时长后，占用第二信道进行数据传输。
其中，第一预设时长可以根据实际情况进行设定。例如，可以设定第一预设时长T 1为与第一信道的MCOT绑定的值，也可以设定第一预设时长T 1为固定的值。
本公开提出的数据传输方法，针对非授权频段上无先听后说的信道接入场景，可以通过响应于当前占用的第一信道的占用时长到达第一信道的占用最大时长MCOT，释放第一信道，并响应于数据传输指令，获取数据传输起始时刻与第一信道的释放时刻之间的第一时间间隔，进而在响应于第一时间间隔到达第一预设时长，占用第二信道进行数据传输，避免了发射端几乎连续占用信道的问题，确保了对其他临近节点不会造成持续干扰等影响，提高了数据传输质量以及数据传输过程中的可靠性和有效性。
进一步地，本公开实施例中，在响应于数据传输指令，获取数据传输起始时刻与第一信道的释放时刻之间的第一时间间隔之后，响应于第一时间间隔未到达第一预设时长，则不发起数据传输。
需要说明的是，本公开实施例中，可选地，第一预设时长可以为与第一信道的MCOT绑定的值，例如可以设定第一预设时长T 1为与第一信道的MCOT呈正相关的值，此种情况下，MCOT越大，第一预设时长T 1的值亦越大；可选地，可以设定第一预设时长T 1为固定值，例如6ms、8ms等。
作为一种可能的实现方式，可以设定第一预设时长为与第一信道的MCOT呈正相关的值，此种情况下，响应于第一时间间隔到达第一预设时长，例如△t 1≥T 1，则可以占用第二信道进行数据传输；响应于第一时间间隔未到达第一预设时长，例如△t 1＜T 1，则可以不发起数据传输。
作为另一种可能的实现方式，可以设定第一预设时长为6ms，此种情况下，响应于第一时间间隔到达第一预设时长，例如△t 1为8ms，则可以占用第二信道进行数据传输；响应于第一时间间隔未到达第一预设时长，例如△t 1为4ms，则可以不发起数据传输。
本公开提出的数据传输方法，可以通过在响应于数据传输指令，获取数据传输起始时刻与第一信道的释放时刻之间的第一时间间隔之后，响应于第一时间间隔未到达第一预设时长，则不发起数据传输，避免了由于采用no-LBT机制，发射端可以立即开始下一次发送所导致的发送端连续占用信道的情况，进一步提高了数据传输质量以及数据传输过程中的可靠性和有效性。
需要说明的是，前述过程未占满MCOT之后，试图再一次占用信道的情况，下面，针对尚未占满MCOT之前的数据传输过程进行解释说明。
需要说明的是，在MCOT尚未结束时，为了避免因采用no-LBT机制，使得发射端可以立即开始下一次发送，进而导致发送端连续占用信道的情况，本公开中，可以获取在所占用信道的MCOT内当次数据传输与前一次数据传输之间的第二时间间隔，并根据第二时间间隔，确定匹配的信道占用策略。
作为一种可能的实现方式，如图2所示，具体包括以下步骤：
步骤201，从每次所占用信道的占用时刻开始，对所占用信道的当前占用时长进行计时。
举例而言，从每次所占用信道的占用时刻开始，对所占用信道的当前占用时长进行计时，并标记为t。
步骤202，响应于当前占用时长未到达所占用信道的MCOT，获取在所占用信道的MCOT内当次数据传输与前一次数据传输之间的第二时间间隔。
本公开实施例中，响应于当前占用时长未到达所占用信道的MCOT，即言MCOT尚未结束，则可以获取在所占用信道的MCOT内当次数据传输与前一次数据传输之间的第二时间间隔。
举例而言，响应于当前占用时长未到达所占用信道的MCOT，获取在所占用信道的MCOT内当次数据传输与前一次数据传输之间的第二时间间隔，并标记为△t 2。
步骤203，响应于第二时间间隔小于或者等于第二预设时长，则继续在所占用信道的MCOT内使用所占用信道传输数据。
步骤204，响应于第二时间间隔大于第二预设时长，则重新占用信道进行数据传输。
需要说明的是，本公开实施例中，可选地，第二预设时长可以为大于默认值，且与所占用信道的MCOT绑定的值，例如若默认值为16us，则可以设定第二预设时长T 2为大于16us，且与所占用信道的MCOT呈正相关的值，此种情况下，MCOT越大，第二预设时长T 2的值亦越大；可选地，可以设定第二预设时长T 2为固定值，例如1ms等。
作为一种可能的实现方式，可以设定第二预设时长为大于默认值，且与所占用信道的MCOT呈正相关的值，此种情况下，响应于第二时间间隔小于或者等于第二预设时长，例如△t 2≤T 2，则可以继续在所述所占用信道的MCOT内使用所述所占用信道传输数据；响应于第二时间间隔大于第二预设时长，例如△t 2＞T 2，则可以重新占用信道进行数据传输。
作为另一种可能的实现方式，可以设定第二预设时长为0.5ms，此种情况下，响应于第二时间间隔小于或者等于第二预设时长，例如△t 2为8us，则可以继续在所述所占用信道的MCOT内使用所述所占用信道传输数据；响应于第二时间间隔大于第二预设时长，例如△t 2为0.7ms，则可以重新占用信道进行数据传输。
本公开提出的数据传输方法，针对非授权频段上无先听后说的信道接入场景，可选地，可以在MCOT尚未结束时，通过获取在所占用信道的MCOT内当次数据传输与前一次数据传输之间的第二时间间隔，并根据第二时间间隔，确定匹配的信道占用策略，能够避免因采用no-LBT机制，使得发射端可以立即开始下一次发送，进而导致发送端连续占用信道的情况。
图3为本申请另一个实施例提出的数据传输方法，如图3所示，具体包括以下步骤：
步骤301，针对所占用的第一信道或第二信道，从所占用信道的占用时刻开始，对所占 用信道的当前占用时长进行计时。
例如，针对所占用的第一信道，从第一信道的占用时刻开始，对第一信道的当前占用时长进行计时，并标记为t 1；又例如，针对所占用的第二信道，从第二信道的占用时刻开始，对第二信道的当前占用时长进行计时，并标记为t 2。
步骤302，响应于当前占用时长未到达所占用信道的MCOT，获取在所占用信道的MCOT内当次数据传输与前一次数据传输之间的第二时间间隔。
本公开实施例中，响应于当前占用时长未到达所占用信道的MCOT，即言MCOT尚未结束，则可以获取在所占用信道的MCOT内当次数据传输与前一次数据传输之间的第二时间间隔。
举例而言，响应于当前占用时长未到达所占用信道的MCOT，获取在所占用信道的MCOT内当次数据传输与前一次数据传输之间的第二时间间隔，并标记为△t 2。
步骤303，响应于第二时间间隔小于或者等于第二预设时长，则继续在所占用信道的MCOT内使用所占用信道传输数据。
步骤304，响应于第二时间间隔大于第二预设时长，则重新占用信道进行数据传输。
需要说明的是，本公开实施例中，可选地，第二预设时长可以为大于默认值，且与所占用信道的MCOT绑定的值，例如若默认值为16us，则可以设定第二预设时长T 2为大于16us，且与所占用信道的MCOT呈正相关的值，此种情况下，MCOT越大，第二预设时长T 2的值亦越大；可选地，可以设定第二预设时长T 2为固定值，例如1ms等。
作为一种可能的实现方式，可以设定第二预设时长为大于默认值，且与所占用信道的MCOT呈正相关的值，此种情况下，响应于第二时间间隔小于或者等于第二预设时长，例如△t 2≤T 2，则可以继续在所述所占用信道的MCOT内使用所述所占用信道传输数据；响应于第二时间间隔大于第二预设时长，例如△t 2＞T 2，则可以重新占用信道进行数据传输。
作为另一种可能的实现方式，可以设定第二预设时长为0.5ms，此种情况下，响应于第二时间间隔小于或者等于第二预设时长，例如△t 2为8us，则可以继续在所述所占用信道的MCOT内使用所述所占用信道传输数据；响应于第二时间间隔大于第二预设时长，例如△t 2为0.7ms，则可以重新占用信道进行数据传输。
进一步地，在占满MCOT后，可以执行如下步骤S305～S307。
步骤305，响应于当前占用的第一信道的占用时长到达第一信道的占用最大时长MCOT，释放第一信道。
本公开实施例中，可以在MCOT结束后，响应于当前占用的第一信道的占用时长到述第一信道的占用最大时长MCOT，释放第一信道。
步骤306，响应于数据传输指令，获取数据传输起始时刻与第一信道的释放时刻之间的 第一时间间隔。
其中，第一时间间隔，指的是两次相邻的发送之间的Gap。
举例而言，响应于数据传输指令，获取数据传输起始时刻与第一信道的释放时刻之间的第一时间间隔，并标记为△t 1。
步骤307，响应于第一时间间隔到达第一预设时长，占用第二信道进行数据传输。
本公开实施例中，在MCOT结束后，可以确保两次相邻的发送之间的第一时间间隔(Gap)达到第一预设时长，进而占用第二信道进行数据传输。
其中，第一预设时长可以根据实际情况进行设定。例如，可以设定第一预设时长T 1为与第一信道的MCOT绑定的值，也可以设定第一预设时长T 1为固定的值。
本公开提出的数据传输方法，针对非授权频段上无先听后说的信道接入场景，可选地，可以在MCOT尚未结束时，通过获取在所占用信道的MCOT内当次数据传输与前一次数据传输之间的第二时间间隔，并根据第二时间间隔，确定匹配的信道占用策略，能够避免因采用no-LBT机制，使得发射端可以立即开始下一次发送，进而导致发送端连续占用信道的情况；可选地，可以在MCOT结束后，通过获取数据传输起始时刻与第一信道的释放时刻之间的第一时间间隔，并根据第一时间间隔，确定匹配的信道占用策略，避免了发射端几乎连续占用信道的问题，确保了对其他临近节点不会造成持续干扰等影响，提高了数据传输质量以及数据传输过程中的可靠性和有效性。

  7. 一种数据传输装置，其特征在于，适用于非授权频段上无先听后说的信道接入场景，所述装置包括：
    释放模块，被配置为响应于当前占用的第一信道的占用时长到达所述第一信道的占用最 大时长MCOT，释放所述第一信道；
    第一获取模块，被配置为响应于数据传输指令，获取数据传输起始时刻与所述第一信道的释放时刻之间的第一时间间隔；
    第一传输模块，被配置为响应于所述第一时间间隔到达第一预设时长，占用第二信道进行数据传输。
  8. 根据权利要求7所述的数据传输装置，其特征在于，所述释放模块，还被配置为：
    响应于所述第一时间间隔未到达所述第一预设时长，则不发起数据传输。
  9. 根据权利要求7所述的数据传输装置，其特征在于，所述第一预设时长与所述第一信道的MCOT正相关；或者，所述第一预设时长为固定值。
  10. 根据权利要求7-9任一项所述的数据传输装置，其特征在于，还包括：
    计时模块，被配置为针对所占用的所述第一信道或所述第二信道，从所占用信道的占用时刻开始，对所述所占用信道的当前占用时长进行计时；
    第二获取模块，被配置为响应于所述当前占用时长未到达所述所占用信道的MCOT，获取在所述所占用信道的MCOT内当次数据传输与前一次数据传输之间的第二时间间隔；
    第二传输模块，被配置为响应于所述第二时间间隔小于或者等于第二预设时长，则继续在所述所占用信道的MCOT内使用所述所占用信道传输数据。
  11. 根据权利要求10所述的数据传输装置，其特征在于，所述第二传输模块，还被配置为：
    响应于所述第二时间间隔大于所述第二预设时长，则重新占用信道进行数据传输。
  12. 根据权利要求10所述的数据传输装置，其特征在于，所述第二预设时长为大于默认值的固定值；或者所述第二预设时长大于默认值，且与所述所占用信道的MCOT正相关。
  13. 一种电子设备，其特征在于，包括：
    至少一个处理器；以及
    与所述至少一个处理器通信连接的存储器；其中，
    所述存储器存储有可被所述至少一个处理器执行的指令，所述指令被所述至少一个处理器执行，以使所述至少一个处理器能够执行权利要求1-6中任一项所述的数据传输方法。
  14. 一种处理器可读存储介质，其特征在于，所述处理器可读存储介质存储有计算机程序，所述计算机程序用于使所述处理器执行权利要求1-6任一项所述的数据传输方法。
