Description

信息传输方法、电子设备和存储介质 技术领域
本申请涉及无线通信领域，例如涉及一种信息传输方法、电子设备和存储介质。
背景技术
第五代移动通信技术(5G，the 5th Generation mobile communication technology，也可以称为新空口(New Radio，NR))的第一阶段的标准制定工作已经完成。从标准制定和技术发展的趋势来看，5G系统致力于研究更高速率、巨量链接、超低时延、更高的可靠性、百倍的能量效率提升等技术指标以支撑新的需求变化。基于NR的非授权频谱接入(NR-based Access to Unlicensed Spectrum，NR-U)技术在物联网、工厂自动化等各方面都有很大的应用前景，但NR-U还面临诸多问题需要解决。
基站作为发起设备时在空闲周期执行空闲信道评估(Clear Channel Assessment，CCA)检测，基站执行CCA检测信道空闲后使用紧邻空闲周期的固定帧周期(Fixed Frame Period，FFP)起始位置开始传输下行数据以及共享剩余信道占用时间(Channel Occupancy Time，COT)用于用户设备(User Equipment，UE)传输上行数据，所述CCA也可以称为先听后说(Listen Before Talk，LBT)，所述UE也可以称为终端。对于UE作为发起设备在空闲周期执行CCA检测以及将剩余COT与基站共享的情况，并没有相应的规则约束UE和基站的行为，同时，UE/基站的COT可能会与基站/UE的空闲周期重叠，这种一个设备的COT与另一个设备的空闲周期重叠的情况可能会带来设备间发起COT的相互阻塞问题，这种阻塞会导致空闲周期所属的设备的CCA执行失败，无法成功发起COT，对信息的传输造成影响。
发明内容
本申请提出一种信息传输方法、电子设备和存储介质，旨在解决终端与基站的COT共享问题，提高复用效率，减少不同设备间发起COT造成的阻塞，提高信息传输效率。
本申请实施例提供了一种信息传输的方法，该方法包括：
根据第二节点的信道占用时间的有效情况和第一节点的上行链路传输触发第一节点的信道占用；确定所述信道占用对应的第一节点的固定帧周期，其中， 所述固定帧周期至少包括信道占用时间和空闲周期；根据所述第一节点的信道占用时间和空闲周期与所述第二节点的信道占用时间和空闲周期的重叠情况确定所述第一节点与所述第二节点的传输。
本申请实施例还提供了一种电子设备，该电子设备包括：
一个或多个处理器；存储器，用于存储一个或多个程序；当所述一个或多个程序被所述一个或多个处理器执行，使得所述一个或多个处理器实现如本申请实施例中任一所述的信息传输方法。
本申请实施例还提供了一种计算机可读存储介质，其上存储有计算机程序，该计算机程序被处理器执行时实现如本申请实施例中任一所述的信息传输方法。
本申请实施例，通过第二节点的有效的信道占用时间和上行链路确定触发第一节点的信道占用的时机，在触发后确定第一节点的信道占用的固定帧周期，通过第一节点的信道占用时间和空闲周期与所述第二节点的信道占用时间和空闲周期的重叠情况确定所述第一节点与所述第二节点的信息传输，实现了信道占用时间的共享，提高了信息传输效率，可减少不同节点之间的信道占用阻塞，提高了信息传输的可靠性。

具体实施方式
此处所描述的具体实施例仅仅用以解释本申请。
在后续的描述中，使用用于表示元件的诸如“模块”、“部件”或“单元”的后缀仅为了有利于本申请的说明，其本身没有特有的意义。因此，“模块”、“部件”或“单元”可以混合地使用。
在相关技术中，对于非授权频谱的使用需要遵循一定的管制政策，例如设备在使用非授权载波发送数据之前必须执行空闲信道评估(Clear Channel Assessment，CCA，也可以称为先听后说(Listen Before Talk，LBT))，只有CCA成功的设备才能在非授权载波上占用信道发送数据，所述CCA成功可以表示信道空闲或未被占用，执行CCA的设备可以在对应的信道中进行信息传输，若CCA失败可以表示信道被占用，执行CCA的设备不可以在对于的信道中进行信息传输。图1是本申请实施例提供的一种基于帧结构的设备的时序图，参见图1，基于帧结构的设备(Frame Based Equipment，FBE)模式包含三个主要参数：固定帧周期(Fixed Frame Period，FFP)，信道占用时间(Channel Occupancy Time，COT)和空闲周期，其中FFP由COT和空闲周期两部分组成。FBE在前一个相邻FFP的空闲周期中执行空闲信道评估(clear channel assessment，CCA)检测，若CCA检测当前信道为空闲，则FBE可以从紧邻的FFP的起始符号开始传输数据；CCA检测当前信道为忙，则FBE不能使用紧邻的FFP的起始符号用于数据传输。FBE模式也可以称为半静态信道接入模式，半静态信道接入模式的信道接入流程周期与FFP是同一个参数的不同表述方式。基站作为发起设备时在空闲周期执行CCA检测，基站执行CCA检测信道空闲后使用紧邻空闲周期的FFP起始位置开始传输下行数据以及共享剩余COT用于UE传输上行数据。对于UE作为发起设备在空闲周期执行CCA检测以及将剩余COT与基站共享的情况，并没有相应的规则约束UE和基站的行为，同时，UE/基站的COT可能会与基站/UE的空闲周期重叠，这种一个设备的COT与另一个设备的空闲周期重叠的情况可能会带来设备间发起COT的相互阻塞问题，这种阻塞会导致空闲周期所属的设备CCA执行失败，无法成功发起COT；此外，若在基站和UE的FFP之间引入偏移值的情况下，该如何定义UE的FFP起始位置也需要明确。
图2是本申请实施例提供的一种信息传输方法的流程图，本实施例可适用于无线通信中共享信道占用时间进行传输的情况，该方法可以由本申请实施例中的信息传输装置来执行，该装置可以通过软件和/或硬件的方式实现，并一般可以集成在软件安装装置中，本申请实施例的方法包括如下步骤：
步骤110、根据第二节点的信道占用时间的有效情况和第一节点的上行链路传输触发第一节点的信道占用。
有效情况可以是第二节点占用的信道时间是否有效的状态，当信道占用时间有效时，第二节点可以使用信道占用时间用于传输或共享信道给其他节点。上行链路可以是传输信息的资源集合，可以由子帧、时隙或者符号等组成。
在本申请实施例的基础上，可以通过第二节点的信道占用时间的有效情况 和第一节点的上行链路传输状态确定是否触发第一节点进行信道占用，例如，当第一节点的上行链路传输位于第二节点的无效的信道占用时间时，第一节点可以触发信道占用。当第一节点的上行链路传输位于第二节点的有效的信道占用时间内，第一节点可以不需要发起信道占用，可以共享第二节点的信道占用时间进行上行链路传输。
步骤120、确定所述信道占用对应的第一节点的固定帧周期，其中，所述固定帧周期至少包括信道占用时间和空闲周期。
在本申请实施例中，触发第一节点的信道占用时，可以确定出信道占用对应的固定帧周期，该固定帧周期可以包括信道占用时间和空闲周期，其中，信道占用时间可以用于发起信道占用的设备传输信息，其中，该信息来自发起信道占用设备，信道占用时间还可以用于发起信道占用的设备共享信道给其他设备传输信息，空闲周期可以用于发起信道占用设备执行空闲信道评估，在所述空闲周期内执行空闲信道评估的结果为空闲则所述发起信道占用设备可以占用紧邻的固定帧周期的信道占用时间用于传输数据和/或所述发起信道占用设备可以共享信道占用时间给其他设备。
步骤130、根据所述第一节点的信道占用时间和空闲周期与所述第二节点的信道占用时间和空闲周期的重叠情况确定所述第一节点与所述第二节点的传输。
由于第一节点包括信道占用时间和空闲周期，而第二节点也包括信道占用时间和空闲周期，当第一节点的信道占用时间/空闲周期与第二节点的空闲周期/信道占用时间存在重叠时，会对第一节点与第二节点的信息传输产生影响，例如，第一节点的信道占用时间与第二节点的空闲周期重叠时，可以阻塞第二节点发起信道占用时间，导致第二节点无法正常发起信道占用时间。可以根据第一节点与第二节点的不同重叠情况确定出第一节点与第二节点对应的传输方式。
本申请实施例，通过第二节点的有效信道占用时间和第一节点的上行链路传输确定触发信道占用的时机，并根据信道占用时间和空闲周期等的重叠情况确定传输方式，实现了信道占用时间的共享，提高了信息传输效率，可减少不同节点之间的信道占用阻塞，提高了信息传输的可靠性。
在上述申请实施例的基础上，所述确定第二节点的信道占用时间的有效情况，包括：
在所述第二节点在空闲周期执行空闲信道评估成功，且所述第二节点在信道占用时间内不存在任意一次传输后大于或等于X毫秒未执行其他传输的情况下，所述第二节点的信道占用时间有效，其中，所述其他传输包括所述第二节点的传输和共享所述信道占用时间的其他节点的传输。
空闲信道评估(Clear Channel Assessment，CCA)可以是节点判断信道是否可用的过程，当节点执行空闲信道评估成功后，可以在对应的信道中进行信息传输，CCA失败可以表示信道被占用或者信道忙，无法在对应的信道中进行信息传输。在本申请实施例中，当第二节点在空闲周期执行空闲信道评估成功后，并且在对应信道中进行信息传输，信息传输过程中不存在大于X毫秒的时间未传输信息，则第二节点对应的信道占用时间有效，信道被第二节点占用用于发送信息。第二节点的信息传输可以包括第二节点使用信道进行信息传输，以及，第二节点将自己的信道占用时间共享给其他节点，由其他节点进行信息传输。
在上述申请实施例的基础上，所述X的取值通过以下至少一种方式确定：
通过无线资源控制信息配置，动态指示和默认值。
在本申请实施例中，X的取值可以通过无线资源控制(Radio Resource Control，RRC)信息进行配置，或者，通过信令的方式进行动态指示，还可以通过预设一个默认值的方式确定。
在上述申请实施例的基础上，所述根据第二节点的信道占用时间的有效情况和第一节点的上行链路传输触发第一节点的信道占用，包括：在所述上行链路的传输起始位置在所述第二节点的有效的信道占用时间内的情况下，所述第一节点共享所述第二节点的信道占用时间用于上行链路传输。
传输起始位置可以是上行链路的传输符号的起始符号，可以表示上行链路开始进行传输的位置。
当上行链路的传输起始位置在第二节点的有效的信道占用时间内时，第二节点的信道占用时间被共享给第一节点使用，第一节点可以共享第二节点发起的信道占用时间进行信息传输。
在上述申请实施例的基础上，所述根据第二节点的信道占用时间的有效情况和第一节点的上行链路传输触发第一节点的信道占用，包括：所述上行链路的传输起始位置和传输结束位置在所述第二节点的同一个有效的信道占用时间内的情况下，则共享所述第二节点的信道占用时间用于上行链路传输，否则，所述第一节点发起信道占用时间用于上行链路传输。
传输结束位置可以是上行链路的结束传输的位置，可以是上行链路的最后符号的位置。
在本申请实施例中，当上行链路的传输起始位置和传输结束位置均位于第二节点的有效的信道占用时间内时，也就是第一节点的上行链路传输整个位于第二节点的有效的信道占用时间内时，则第一节点可以共享第二节点的信道占用时间进行信息发送。否则，第一节点的上行链路传输存在部分或者全部不在 第二节点的有效的信道占用时间内，则需要第一节点发起信道占用，确定一个信道占用时间来发送上行链路传输。
在上述申请实施例的基础上，所述根据第二节点的信道占用时间的有效情况和第一节点的上行链路传输触发第一节点的信道占用，包括：
在配置和/或调度的上行链路的传输起始位置与所述第一节点的固定帧周期的起始位置对齐，且所述上行链路传输不在所述第二节点的有效的信道占用时间内的情况下，则所述第一节点发起信道占用时间用于上行链路传输。
上行链路传输的配置信息或者调度信息指示上行链路的起始位置与第一节点的固定帧周期的起始位置对齐，上行链路传输可以在第一节点的信道占用时间的起始位置处进行传输，并且上行链路传输不在第二节点的有效的信道占用时间内，此时第一节点的上行链路传输无法在第二节点的信道占用时间内进行传输，第一节点可以发起自己的信道占用时间以用于上行链路传输。
在上述申请实施例的基础上，还包括：第一节点未配置基于帧结构的设备参数，则所述第一节点共享所述第二节点的信道占用时间用于上行链路传输。
基于帧结构的设备参数可以是第一节点发起信道占用的参数，第一节点可以根据该参数确定占用信道的时长和周期等信息，基于帧结构的设备参数可以包括发送固定帧周期、信道占用时间和空闲周期等参数。
在本申请实施例中，当第一节点未配置有基于帧结构的设备参数时，第一节点无法发起信道占用，第一节点的上行链路传输可以共享第二节点的信道占用时间进行发送。
在上述申请实施例的基础上，所述基于帧结构的设备参数至少包括固定帧周期。
在一个示例性的实施方式中，终端设备UE作为第一节点工作在FBE模式下，基站在空闲周期执行CCA成功并占用紧邻的FFP的COT用于数据传输，对于基站来说当前COT是否为有效的COT有以下两种可能：(1)基站在空闲周期执行CCA成功后，紧邻的FFP的COT对于基站来说都是有效的COT，基站可以使用该COT用于数据传输或者共享给其他设备用于传输其他设备的数据。(2)基站在空闲周期执行CCA成功后，在紧邻的FFP的COT内任意一个传输之后超过X毫秒没有数据传输的情况下，视为所述基站释放了所述COT，也即所述COT在所述任意一个传输之后的部分对于所述基站来说不属于有效的COT；所述X的取值由无线资源控制(Radio Resource Control，RRC)信息配置、动态控制信息通知或设置为一个默认值。
基站在空闲周期执行CCA成功后，在紧邻的FFP的COT内任意一个传输 之后超过25us没有数据传输，则视为所述基站在所述任意一个传输之后释放了所述COT，也即所述COT在所述任意一个传输之后的部分对所述基站不是一个有效的COT。图3是本申请实施例提供的一种有效信道占用时间的示意图，参见图3，基站在前一个FFP的空闲周期执行CCA成功后，对于第2种可能来说，第二个斜纹传输之后超过X毫秒都没有任何传输，则视为基站释放了当前FFP的COT，对于基站来说实际有效的COT只有前半部分。
UE的上行链路(Uplink，UL)传输起始位置在基站的有效的COT内，则UE共享基站的COT用于所述UL传输；UE的UL传输起始位置及结束位置均在基站的同一个有效的COT内，则UE共享基站的COT用于所述UL传输，否则，UE需要发起一个COT用于所述UL传输。
UE调度的UL传输或者配置的UL传输起始位置与UE的FFP的起始位置对齐且所述UL传输不在基站的有效COT内，则UE需要发起一个COT用于所述UL传输，其中所述不在基站的有效COT内包含两种情况：1)基站在当前COT所述的FFP之前的空闲周期执行CCA失败，未能抢占到信道的使用权；2)基站的COT已经释放。
UE没有配置部分FBE相关的参数的情况下，则UE不具备发起COT的能力，所述UE只能通过共享基站的COT发送UL传输，例如，UE在没有配置FFP的情况下，隐含指示UE不具备发起COT的能力，该UE只能通过共享基站的COT用于UL传输。
图4是本申请实施例提供的一种信息传输方法的流程图，本申请实施例是在上述实施例基础上的说明，参见图4，本申请实施例提供的方法包括如下步骤：
步骤210、根据第二节点的信道占用时间的有效情况和第一节点的上行链路传输触发第一节点的信道占用。
步骤220、在固定帧周期取值范围内选择目标值以作为固定帧周期。
固定帧周期取值范围可以是一个取值范围，包括至少一个数值，固定帧周期取值范围可以预先设置在终端内部或者通过上层信令进行指示。
在本申请实施例中，可以在固定帧周期取值范围内选择一个数值作为固定帧周期，示例性的，固定帧周期的取值范围可以为集合{1，2，2.5，4，5，10}中的至少一个取值。
步骤230、根据所述第一节点的信道占用时间和空闲周期与所述第二节点的信道占用时间和空闲周期的重叠情况确定所述第一节点与所述第二节点的传输。
本申请实施例，通过第二节点的信道占用时间的有效情况和第一节点的上行链路传输触发第一节点的信道占用，在固定帧周期取值范围内确定信道占用 的固定帧周期，基于第一节点的信道占用时间和空闲周期与所述第二节点的信道占用时间和空闲周期的重叠情况确定所述第一节点与所述第二节点的传输，实现了信道占用时间的共享，提高了信息传输效率，可减少不同节点之间的信道占用阻塞，提高了信息传输的可靠性。
在上述申请实施例的基础上，所述固定帧周期取值范围包括以下至少一种：所述第二节点的固定帧周期取值范围的子集，所述第二节点的固定帧周期取值范围包括集合{1，2，2.5，4，5，10}；集合{1，1.25，2，2.5，4，5，10}的子集。
在本申请实施例中，第一节点的固定帧周期取值范围可以为第二节点的固定帧周期取值范围的子集，第二节点的固定帧周期取值范围包括集合{1，2，2.5，
4，5，10}，相应的，第一节点的固定帧周期取值范围可以为{1，2，2.5，4}或者{1，2，2.5，4，5，10}等。第一节点的固定帧周期取值范围可以与第二节点不相关，可以由集合{1，2，2.5，4，5，10}确定，第一节点的固定帧周期取值范围可以为集合{1，2，2.5，4，5，10}的子集，包括该集合中的至少一个取值。
在上述申请实施例的基础上，所述固定帧周期的起始位置与(M/10)*N号无线帧边界存在偏移值，其中M为第一节点的固定帧周期取值范围内的所有值的最小公倍数或第一节点的固定帧周期取值范围内的所有值和10的最小公倍数，M和N为非负整数。

在一个示例性的实施方式中，UE的FFP的取值范围可以与基站的FFP的取值保持一致，也即UE的FFP为集合{1，2，2.5，4，5，10}中的一个值；UE的FFP的取值也可以是集合{1，1.25，2，2.5，4，5，10}中的一个值。
基站的FFP与UE的FFP的起始位置之间存在偏移值，则偏移值为0到UE的FFP取值集合中所有值的最小公倍数；所述偏移值为0到UE的FFP取值集 合中所有值和10的最小公倍数。所述最小公倍数为M且基站的FFP与UE的FFP的起始位置之间的偏移值为0的情况下，UE的FFP需要与(M/10)*N无线帧边界对齐，其中M和N为非负整数；UE的FFP在偏移值为0的情况下与偶数无线帧对齐。
偏移值记为offset，UE的FFP取值记为P，则UE的FFP从距离(M/10)*N无线帧边界offset+i*P起始，其中i为集合{0，1，...，M/P-1}中的一个值。图5是本申请实施例提供的一种固定帧周期的起始位置的确定示意图，参见图5，例如，UE的FFP为5ms，UE的FFP的所有取值的最小公倍数为20，offset为0ms，则UE的FFP中，每两个无线帧对应的第一个FFP的起始位置与偶数无线帧对齐，在两个无线帧中总共包含4个UE的FFP，其中UE的第0、1、2、3个FFP的起始位置分别为距离偶数无线帧边界0、5、10、15ms的位置；若所述offset为2ms，其参数不变，则在每20ms中包含4个完整的UE的FFP，在所述20ms中，UE的第0、1、2、3个FFP的起始位置分别为距离偶数无线帧边界2+0*5、2+1*5、2+2*5、2+3*5ms的位置，如图5所示。
在上述申请实施例的基础上，在所述第二节点共享所述第一节点发起的信道占用的情况下，根据所述第一节点的信道占用时间和空闲周期与所述第二节点的信道占用时间和空闲周期的重叠情况确定所述第一节点与所述第二节点的传输，包括：
所述第一节点的所述信道占用时间与所述第二节点的空闲周期的重叠位置用于所述第二节点的信息传输。
在本申请实施例中，在确定出第一节点与第二节点的传输过程中，第一节点发起信道占用时间，第二节点共享该信道占用共享时间时，可以将第一节点的信道占用时间与第二节点的空闲周期重叠的位置作为第二节点的信息传输的资源使用。
在上述申请实施例的基础上，所述信息传输基于所述第二节点的决策信息确定。
决策信息可以是第二节点用于确定是否进行信息传输的信息，决策信息可以由第二节点本地生成，也可以由上层指令指示。
第二节点可以通过决策信息自主决定是否使用第一节点的信道占用时间与第二节点的空闲周期重叠的位置进行信息传输。
在上述申请实施例的基础上，在所述第二节点共享所述第一节点发起的信道占用的情况下，根据所述第一节点的信道占用时间和空闲周期与所述第二节点的信道占用时间和空闲周期的重叠情况确定所述第一节点与所述第二节点的 传输，包括：所述第一节点的信道占用时间与所述第二节点的空闲周期的重叠位置不用于所述第二节点的信息传输。
在本申请实施例中，当第一节点共享信道占用时间时，若第二节点的空闲周期与第一节点共享的信道占用时间存在重叠，则第二节点不使用第二节点的空闲周期与第一节点共享的信道占用时间存在重叠的部分进行信息传输。
在上述申请实施例的基础上，在所述第一节点共享所述第二节点发起的信道占用的情况下，根据所述第一节点的信道占用时间和空闲周期与所述第二节点的信道占用时间和空闲周期的重叠情况确定所述第一节点与所述第二节点的传输，包括：所述第一节点在所述第二节点的信道占用时间与所述第一节点的空闲周期的重叠位置传输信息。
在本申请实施例中，当第二节点发起信道占用，并共享给第一节点使用时，第一节点可以通过第二节点的信道占用时间与第一节点的空闲周期重叠的位置传输信息。

第三节点可以是与第一节点不同的设备，第三节点可以为其他的用户终端。
若第二节点发起信道占用时间，那么第一节点的空闲周期与第二节点的信道占用时间重叠时，该重叠位置可以被第二节点共享以进行信息传输，或者，被第三节点使用该重叠位置进行信息传输。
在上述申请实施例的基础上，在所述第一节点发起的信道占用的情况下，所述根据所述第一节点的信道占用时间和空闲周期与所述第二节点的信道占用时间和空闲周期的重叠情况确定所述第一节点与所述第二节点的传输，包括：所述第一节点不在所述第一节点的信道占用时间与所述第二节点的空闲周期的重叠位置传输信息和/或共享所述第一节点的信道占用时间给第三节点。
在本申请实施例中，第一节点发起信道占用，且第一节点的信道占用时间与第二节点的空闲周期存在重叠，则第一节点不使用该重叠位置进行信息传输或者共享给第三节点进行信息传输。
在一个示例性的实施方式中，在UE/基站的空闲周期与基站/UE的COT重叠位置，是否允许基站/UE传输数据会影响到UE/基站是否可以成功发起信道占用，也即基站/UE在所述重叠位置的传输会阻塞所述UE/基站发起信道占用。
基站作为共享设备，共享UE的COT，所述基站自己决定是否可以在UE的COT与所述基站的空闲周期重叠的位置传输数据，也即所述基站在共享UE 的COT的时候，所述基站的传输是否可以阻塞所述基站发起COT由所述基站自主决定。例如基站仅需要传输部分数据给所述UE，所述基站可以直接共享所述UE的COT完成数据传输；基站需要传输大量的数据或者需要给其他UE传输单播数据的情况下，所述基站在所述UE的COT与所述基站的空闲周期重叠的位置不发送数据，所述基站在空闲周期执行CCA检测，CCA检测信道空闲则使用下一个FFP的COT传输数据。
基站作为共享设备，共享UE的COT，则所述基站在UE的COT与所述基站的空闲周期重叠的位置不能传输数据，也即所述基站在共享UE的COT的时候，所述基站的传输不可以阻塞基站发起COT。图6是本申请实施例提供的一种固定帧周期的重叠位置的示意图，如图6所示，基站在FFP0未成功发起COT，而UE在FFP0成功发起COT，所述基站可以共享所述UE的COT用于数据传输；资源1为所述UE的COT与所述基站的空闲周期重叠的位置，则所述基站不能使用所述资源1用于传输所述基站的数据，也即需要预留基站执行CCA发起COT的资源，不能阻塞基站发起COT。
UE作为共享设备，共享基站的COT，所述UE可以在所述基站的COT与所述UE的空闲周期重叠的位置发送数据，也即所述UE在共享基站的COT的时候，所述UE的传输可以阻塞所述UE发起COT。如图6所示，基站在FFP1发起COT成功，而UE在FFP1没有成功发起COT，所述UE可以共享所述基站的COT用于数据传输；资源2为所述基站的COT与所述UE的空闲周期重叠的位置，则所述UE可以使用所述资源2用于传输所述UE的数据，也即UE共享基站的COT的情况下，所述UE的传输可以阻塞所述UE发起COT。
基站作为发起设备，在所述基站的COT与UE的空闲周期重叠的位置，允许基站传输数据和共享COT给其他设备；也即在基站的COT中，所述基站的传输或者共享所述基站的COT的其他设备的传输可以阻塞所述UE发起COT。参见图6，基站在FFP1发起COT成功，而UE在FFP1没有成功发起COT，资源2为所述基站的COT与所述UE的空闲周期重叠的位置，则所述基站或者共享所述基站的COT的其他设备的传输可以使用所述资源2用于数据传输，也即所述基站的传输或者共享所述基站的COT的其他设备可以阻塞所述UE发起COT。
UE作为发起设备，在所述UE的COT与基站的空闲周期重叠的位置，不允许UE传输数据和共享COT给其他设备。也即在UE的COT中，所述UE的传输或者共享所述UE的COT的其他设备的传输不可以阻塞所述基站发起COT。参见图6，基站在FFP0未成功发起COT，而UE在FFP0成功发起COT，资源1为所述UE的COT与所述基站的空闲周期重叠的位置，则所述UE的传输或者 共享所述UE的COT的其他社诶的传输不可以阻塞所述基站发起COT。
