在非授权频段上部署的通信系统通常采用竞争的方式来使用或者共享无线资源。为了保证公平性，在非授权频段上进行传输的设备通常需要遵守先听后说(listen before talk，LBT)规则，即在发送信号之前需要先进行侦听信道。在侦听到信道空闲时进行通信传输。其中，终端设备进行通信传输时对侦听到空闲信道的占用并非永久占用，而是会确定一个占用时间，该占用时间可以称作COT，终端设备在该COT内占用空闲的非授权频段。
相关技术中，终端设备之间支持COT共享，以充分利用信道资源。其中，COT共享时，发起COT的终端设备需要发送COT共享信息，共享COT的终端设备需要根据COT共享信息来确定能否/如何使用发起COT的终端设备所共享的COT。然而，相关技术中对于COT共享信息如何在终端设备间进行发送并未明确。

具体实施方式
这里将详细地对示例性实施例进行说明，其示例表示在附图中。下面的描述涉及附图时，除非另有表示，不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本公开相一致的所有实施方式。
本公开实施例提供的COT共享的方法可应用于图1所示的无线通信系统中。参阅图1所示，该无线通信系统中包括但不限于第一终端设备和第二终端设备。第一终端设备通过无线资源与第二终端设备相连接，并进行数据传输。
其中，在本公开实施例中，第一终端设备也可被称为发起COT的终端设备，第二终端设备也可被称为共享COT的终端设备。
可以理解的是，图1所示的无线通信系统仅是进行示意性说明，无线通信系统中还可包括网络设备，例如还可以包括核心网设备、无线中继设备和无线回传设备等，在图1中未画出。本公开实施例对该无线通信系统中包括终端数量不做限定。
进一步可以理解的是，本公开实施例无线通信系统，是一种提供无线通信功能的网络。无线通信系统可以采用不同的通信技术，例如码分多址(code division multiple access,CDMA)、宽带码分多址(wideband code division multiple access，WCDMA)、时分多址(time division multiple access，TDMA)、频分多址(frequency division multiple access，FDMA)、正交频分多址(orthogonal frequency-division multiple access，OFDMA)、单载波频分多址(single Carrier FDMA，SC-FDMA)、载波侦听多路访问/冲突避免(Carrier Sense Multiple Access with Collision Avoidance)。根据不同网络的容量、速率、时延等因素可以将网络分为2G(英文：generation)网络、3G网络、4G网络或者未来演进网络，如5G网络，5G网络也可称为是新无线网络(New Radio，NR)。为了方便描述，本公开有时会将无线通信网络简称为网络。
进一步的，本公开中涉及的终端设备，也可以称为终端、用户设备(User Equipment，UE)、移动台(Mobile Station，MS)、移动终端(Mobile Terminal，MT)等，是一种向用户提供语音和/或数据连通性的设备，例如，终端可以是具有无线连接功能的手持式设备、 车载设备等。目前，一些终端的举例为：智能手机(Mobile Phone)、客户前置设备，口袋计算机(Pocket Personal Computer，PPC)、掌上电脑、个人数字助理(Personal Digital Assistant，PDA)、笔记本电脑、平板电脑、可穿戴设备、或者车载设备等。此外，当为车联网(V2X)通信系统时，终端设备还可以是车载设备。应理解，本公开实施例对终端所采用的具体技术和具体设备形态不做限定。
在非授权频段上部署的通信系统通常采用竞争的方式来使用或者共享无线资源。为了保证公平性，在非授权频段上进行传输的设备通常需要遵守先听后说(listen beforetalk，LBT)规则，即在发送信号之前需要先进行侦听信道。在侦听到信道空闲时进行通信传输。其中，终端设备进行通信传输时对侦听到空闲信道的占用并非永久占用，而是会确定一个占用时间，该占用时间可以称作COT，终端设备在该COT内占用空闲的非授权频段。
相关技术中，终端设备之间支持COT共享，以充分利用信道资源。其中，COT共享时，发起COT的终端设备需要发送COT共享信息，共享COT的终端设备需要根据COT共享信息来确定能否/如何使用发起COT的终端设备所共享的COT。然而，相关技术中对于COT共享信息如何在终端设备间进行发送并未明确。
基于此，本公开实施例提供一种COT共享的方法，第一终端设备在第一时间发起COT；并在第二时间向第二终端设备发送COT共享信息。其中，第二时间基于第一时间确定，因此，本公开实施例中第一终端设备可以基于发起COT的时间确定发送COT共享信息的时间。并且，第二终端设备能够基于第一终端设备发起COT的第一时间确定接收COT共享信息的第二时间，进而在第二时间接收COT共享信息，能够使第二终端设备及时准确的接收COT共享信息并及时解码COT共享信息，以便基于COT共享信息进行COT共享，提高了COT共享的效率。
图2是根据一示例性实施例示出的一种COT共享的方法的流程图，如图2所示，COT共享的方法由第一终端设备执行，包括以下步骤。
在步骤S11中，在第一时间发起COT。
在步骤S12中，在第二时间向第二终端设备发送COT共享信息，第二时间基于第一时间确定。
在本公开实施例中，第一终端设备在第一时间发起COT；并在第二时间向第二终端设备发送COT共享信息。其中，第二时间基于第一时间确定，因此，本公开实施例中第一终端设备可以基于发起COT的时间确定发送COT共享信息的时间。并且，第二终端设备能够基于第一终端设备发起COT的第一时间确定接收COT共享信息的第二时间，进而在 第二时间接收COT共享信息，能够使第二终端设备及时准确的接收COT共享信息并及时解码COT共享信息，以便基于COT共享信息进行COT共享，提高了COT共享的效率。
一种实现方式中，COT共享信息包括以下至少一种：COT剩余长度、COT ID、信道接入方式，信道接入优先级。
举例而言，第一终端设备可以使用类型1(Type 1)的LBT方式接入信道，发起一个一定长度的COT，根据具体情况，确定COT剩余长度，并在与第二终端设备进行通信时携带包括COT剩余长度、COT ID以及信道接入方式中至少一种的COT共享信息。
其中，COT剩余长度可理解为可供第二终端设备使用的COT的长度，可以由第一终端设备基于不同情况确定得出。
在本公开实施例中提供的一种COT共享的方法中，COT共享信息可以单独被发送，或者，COT共享信息和第一终端设备的通信数据一起被发送。
一种实现方式中，可以通过直连通信携带共享COT信息，以将共享COT信息发送给第二终端设备；或者，通过MAC CE携带共享COT信息，以将共享COT信息发送给第二终端设备。
在本公开实施例中提供的一种COT共享的方法中，第二时间等于或晚于第一时间。
在本公开实施例中提供的一种COT共享的方法中的一种实施方式中，若第二时间晚于第一时间，第二时间为在第一时间发起的COT的第m个时隙，m为大于1的整数。
图3是根据一示例性实施例示出的一种COT共享的方法的流程图，如图3所示，包括以下步骤。
在步骤S21中，在第一时间发起COT。
在步骤S22中，在第一时间发起的COT的第m个时隙，向第二终端设备发送COT共享信息。
在本公开实施例中提供的一种COT共享的方法中的另一种实施方式中，若第二时间等于第一时间，则第二时间为在第一时间发起的COT的第一个时隙。
图4是根据一示例性实施例示出的一种COT共享的方法的流程图，如图4所示，包括以下步骤。
在步骤S31中，在第一时间发起COT。
在步骤S32中，在第一时间发起的COT的第一个时隙，向第二终端设备发送COT共享信息。
在本公开实施例中，通过在第一终端设备发起COT的第一个时隙，向第二终端设备发送COT共享信息，可以使第二终端设备及时接收COT共享信息并判断第二终端设备所 使用的COT起始位置和结束位置，减少解码COT共享信息的时延。
在本公开实施例中，第一终端设备每发起一次COT共享，第一终端设备均会在发起COT之后的第一个或第m个时隙，向第二终端设备发送一次COT共享信息，也即第一终端设备发起COT共享的次数和发送COT共享信息的次数相同。
在本公开实施例中提供的一种COT共享的方法中，在第一时间发起的COT包括预留的在第三时间发起的COT。
其中，第三时间为一个或多个周期性时间，或，第三时间为一个或多个非周期性时间。
图5是根据一示例性实施例示出的一种COT共享的方法的流程图，如图5所示，包括以下步骤。
在步骤S41中，在第一时间发起COT，在第一时间发起的COT包括预留的在第三时间发起的COT。
在步骤S42中，在第二时间向第二终端设备发送COT共享信息。
需要说明的是，步骤S41-S42既可以单独被实施，也可以配合本公开的任何一个实施例一起被实施，在此不再赘述。
在本公开实施例中，第一终端设备发起COT的次数和发送COT共享信息的次数不同。第一终端设备会在第一时间发起COT时预留第三时间发起的COT。可以理解的是，第一终端设备在某次发起COT共享后，在第二时间向第二终端设备发送一次COT共享信息。此后，当第一终端设备在第三时间发起COT时，第一终端设备将不会向第二终端设备发送COT共享信息，第二终端设备直接使用预留的COT。
在本公开实施例中，在第一时间发起的COT和预留的在第三时间发起的COT的长度相同。
在本公开实施例中提供的一种COT共享的方法中，COT共享信息中携带第一指示信息，第一指示信息用于指示在第一时间发起的COT是否预留有在第三时间发起的COT。
在本公开实施例提供的一种COT共享的方法中的一种实施方式中，第一指示信息中包括比特信息，通过比特信息指示是否预留了在第三时间发起的COT。
一示例性实施例中，响应于比特信息为1，第一终端设备在第一时间发起的COT预留了在第三时间发起的COT。或，响应于比特信息为0，第一终端设备在第一时间发起的COT未预留在第三时间发起的COT。
在本公开实施例提供的一种COT共享的方法中，响应于第一时间发起的COT预留有在第三时间发起的COT，确定第三时间为一个或多个周期性时间或一个或多个非周期性时间。
一种实施方式是，基于第一阶段侧链路控制信息(Sidelink Control information，SCI)确定第三时间是否为周期性时间。
一示例性实施例中，若第一阶段SCI中存在resource reservation
Figure PCTCN2022126531-appb-000001
信息字段，则确定第三时间为周期性时间，且第三时间的周期基于resource reservation
Figure PCTCN2022126531-appb-000002
信息字段中的
Figure PCTCN2022126531-appb-000003
确定。
例如，基于resource reservation
Figure PCTCN2022126531-appb-000004
信息字段中的
Figure PCTCN2022126531-appb-000005
确定的周期为P1，如图6所示，第一终端设备在第一时间基于LBT成功并发起1个长度为M个时隙的COT，并在第二时间(时隙N)向第二终端设备发送COT共享信息，从第一时间发起的COT预留了从时隙(N+P1)开始的长度为M的COT，也预留了从时隙(N+2P1)开始的长度为M的COT，也即第一终端设备预留了从时隙(N+gP1)开始的长度为M的COT。其中，g为大于1的整数。
另一种实施方式是，若第一阶段SCI中不存在resource reservation
Figure PCTCN2022126531-appb-000006
信息字段，则第三时间为一个或多个非周期性时间。
在本公开实施例提供的一种COT共享的方法中，若第三时间为一个或多个非周期性时间，第三时间与第二时间之间的时间间隔小于或等于时间阈值。
在本公开实施例中，若确定第三时间为一个或多个非周期性时间，则基于时间阈值盲检第三时间，只要满足第三时间与第二时间之间的时间间隔小于或等于时间阈值即可，无需指示信息指示具体的第三时间。
在本公开实施例提供的一种COT共享的方法中，时间阈值基于以下至少一项确定：
预定义；
预先配置；
SCI指示。
在本公开实施例提供的一种COT共享的方法中，第三时间的个数基于以下至少一项确定：
预定义；
预先配置；
SCI指示。
一示例性实施例中，如图7所示，第一终端设备在第一时间发起了1个长度为M个时隙的COT，并在第二时间(时隙N)向第二终端设备发送了COT共享信息，COT共享信息中携带的第一指示信息指示预留了在时隙(N+x)开始的长度为M的COT(x＞M)，也 预留在时隙(N+y)开始的长度为M的COT，(y＞M)，第二指示信息最多可以预留a次COT，每次预留的COT长度都为M个时隙，且第一时间发起的COT的第一个时隙和预留的a次COT的第一个时隙之间的时间间隔最长分布在时间阈值(b个slot)之间。
例如，类似于R16中SCI预留资源之间，所有预留的COT的第一个时隙和第一时间发起的COT的第一个时隙之间分布在32个时隙之间。
在本公开实施例中，通过指示在第一时间发起的COT周期性或非周期性地预留第三时间的COT，节省了信令消耗。
图8是根据一示例性实施例示出的一种COT共享的方法的流程图，如图8所示，COT共享的方法由第二终端设备执行，包括以下步骤。
在步骤S51中，在第二时间接收第一终端设备发送的COT共享信息，第二时间基于第一终端设备发起COT的第一时间确定。
在本公开实施例中，第一终端设备在第一时间发起COT；并在第二时间向第二终端设备发送COT共享信息。其中，第二时间基于第一时间确定，因此，本公开实施例中第一终端设备可以基于发起COT的时间确定发送COT共享信息的时间。并且，第二终端设备能够基于第一终端设备发起COT的第一时间确定接收COT共享信息的第二时间，进而在第二时间接收COT共享信息，能够使第二终端设备及时准确的接收COT共享信息并及时解码COT共享信息，以便基于COT共享信息进行COT共享，提高了COT共享的效率。在本公开实施例中提供的一种COT共享的方法中，COT共享信息可以单独被接收，或者，COT共享信息和第一终端设备的通信数据一起被接收。
一种实现方式中，可以通过直连通信接收第一终端设备发送的共享COT信息；或者，MAC CE携带共享COT信息，通过接收MAC CE接收第一终端设备发送的共享COT信息。
在本公开实施例中提供的一种COT共享的方法中，第二时间等于或晚于第一时间。
在本公开实施例中提供的一种COT共享的方法中的一种实施方式中，若第二时间晚于第一时间，第二时间为在第一时间发起的COT的第m个时隙，m为大于1的整数。
图9是根据一示例性实施例示出的一种COT共享的方法的流程图，如图9所示，包括以下步骤。
在步骤S61中，在第一时间发起的COT的第m个时隙，接收第一终端设备发送的COT共享信息。

图10是根据一示例性实施例示出的一种COT共享的方法的流程图，如图10所示， 包括以下步骤。
在步骤S71中，在第一时间发起的COT的第一个时隙，接收第一终端设备发送的COT共享信息。
在本公开实施例中，通过在第一终端设备发起COT的第一个时隙，接收第一终端设备发送的COT共享信息，可以使第二终端设备尽早接收到COT共享信息并判断第二终端设备所使用的COT起始位置和结束位置，减少解码COT共享信息的时延。
在本公开实施例中，第一终端设备每发起一次COT共享，第一终端设备均会在发起COT的第一个时隙或第m个时隙，向第二终端设备发送一次COT共享信息，也即第一终端设备发起COT共享的次数和发送COT共享信息的次数相同。
在本公开实施例中提供的一种COT共享的方法中，在第一时间发起的COT包括预留的在第三时间发起的COT。
其中，第三时间为一个或多个周期性时间，或，第三时间为一个或多个非周期性时间。
在本公开实施例中，第一终端设备发起COT的次数和发送COT共享信息的次数不同。第一终端设备会在第一时间发起COT时预留第三时间发起的COT。可以理解的是，第一终端设备在某次发起COT共享后，第二终端设备在第二时间接收到一次COT共享信息。此后，当第一终端设备在第三时间发起COT时，第二终端设备将不会接收到第一终端设备发送的COT共享信息，第二终端设备直接使用预留的COT。
在本公开实施例中，在第一时间发起的COT和预留的在第三时间发起的COT的长度相同。

在本公开实施例提供的一种COT共享的方法中的一种实施方式中，第一指示信息中包括比特信息，通过比特信息指示是否预留了在第三时间发起的COT。
一示例性实施例中，响应于比特信息为1，第一终端设备在第一时间发起的COT预留了在第三时间发起的COT。或，响应于比特信息为0，第一终端设备在第一时间发起的COT未预留在第三时间发起的COT。
在本公开实施例提供的一种COT共享的方法中，响应于第一时间发起的COT预留有在第三时间发起的COT，确定第三时间为一个或多个周期性时间或一个或多个非周期性时间。
一种实施方式是，基于第一阶段侧链路控制信息(Sidelink Control information，SCI)确定第三时间是否为周期性时间。
一示例性实施例中，若第一阶段SCI中存在resource reservation
Figure PCTCN2022126531-appb-000007
信息字段，则确定第三时间为周期性时间，且第三时间的周期基于resource reservation
Figure PCTCN2022126531-appb-000008
信息字段中的
Figure PCTCN2022126531-appb-000009
确定。
另一种实施方式是，若第一阶段SCI中不存在resource reservation
Figure PCTCN2022126531-appb-000010
信息字段，则第三时间为一个或多个非周期性时间。
在本公开实施例提供的一种COT共享的方法中，若第三时间为一个或多个非周期性时间，第三时间与第二时间之间的时间间隔小于或等于时间阈值。
在本公开实施例中，若确定第三时间为一个或多个非周期性时间，则基于时间阈值盲检第三时间，只要满足第三时间与第二时间之间的时间间隔小于或等于时间阈值即可，不存在指示信息指示具体的第三时间。

预定义；
