具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
下面先对本发明所涉及的一些术语做一个简要的说明，如下所示：
1、信道占用时间(Channel Occupancy Time，COT)共享(sharing)
相比R15新无线(New Radio，NR)，在非授权频谱上的NR(NR-based access to unlicensed spectrum，NR-U)系统中，随机接入信道(Random Access Channel，RACH)过程中的信道发送需要考虑信道接入的影响。为了尽量减少由于先听后说(Listen before talk，LBT)失败造成的RACH过程的延迟：
一方面，在RACH过程中同样支持信道占用共享(COT sharing，具体细节可参考18.2.2章节)。当基站在发送Msg2时，可以将基站获得的COT共享给用户设备(User Equipment，UE)进行Msg3的发送。否则，UE在发送Msg3时需要进行LBT以获得信道接入，会存在LBT失败的可能，从而带来Msg3的发送延迟。在上述方案中，基站在发送Msg2时，可以根据自身的COT情况，在Msg2中携带UE用于发送Msg3需要采用的LBT的类型。
另一方面，在基站发送Msg2时，考虑到潜在的LBT失败问题，其在UE的随机接入响应(Random Access Response，RAR)接收窗口内有可能不能及时获得信道接入从而导致无法发送Msg2。因此NR-U系统中对RAR接收窗口的最大长度进行了扩大，即从R15定义的最大10ms的RAR接收窗口扩大到40ms，以便于基站可以有更多的时间进行信道接入，避免因为LBT失败造成RAR无法及时发送。
2、动态信道监听
动态信道监听也可以认为是基于负载的设备(Load based equipment，LBE)的LBT方式，其信道监听原则是通信设备在业务到达后进行非授权频谱的载波上的LBT，并在LBT成功后在该载波上开始信号的发送。动态信道监听的LBT方式包括类型1(Type1)信道接入方式和类型2(Type2)信道接入方式。
Type1信道接入方式为基于竞争窗口大小调整的随机回退的多时隙信道检测，其中，根据待传输业务的优先级可以选择对应的信道接入优先级(Channel access priority class，CAPC)p。
Type2信道接入方式为基于固定长度的监听时隙的信道接入方式，其中，Type2信道接入方式包括Type2A信道接入、Type2B信道接入和Type2C信道接入。
Type1信道接入方式主要用于通信设备发起信道占用，Type2信道接入方式主要用于通信设备共享信道占用。
3、基站侧的信道占用时间共享(COT Sharing)
当基站发起COT后，除了可以将该COT内的资源用于下行传输，还可以将该COT内的资源共享给UE进行上行传输。COT内的资源共享给UE进行上行传输时，UE可以使用的信道接入方式为Type2A信道接入、Type2B信道接入或Type2C信道接入，其中，Type2A信道接入、Type2B信道接入和Type2C信道接入均为基于固定长度的监听时隙的信道接入方 式。
Type2A信道接入：UE的信道检测方式为25μs的单时隙信道检测。具体地，Type2A信道接入下，UE在传输开始前可以进行25μs的信道监听，并在信道监听成功后进行传输。
Type2B信道接入：UE的信道检测方式为16μs的单时隙信道检测。具体地，Type2B信道接入下，UE在传输开始前可以进行16μs的信道监听，并在信道监听成功后进行传输。其中，该传输的起始位置距离上一次传输的结束位置之间的空隙大小为16μs。
Type2C信道接入：UE在空隙结束后不做信道检测而进行传输。具体地，Type2C信道接入下，UE可以直接进行传输，其中，该传输的起始位置距离上一次传输的结束位置之间的空隙大小为小于或等于16μs。其中，该传输的长度不超过584μs。
不同的COT共享场景下应用的信道接入方案不同。在基站的COT内发生的上行传输机会，如果该上行传输机会的起始位置和下行传输机会的结束位置之间的空隙小于或等于16μs，UE可以在该上行传输前进行Type2C信道接入；如果该上行传输机会的起始位置和下行传输机会的结束位置之间的空隙等于16μs，UE可以在该上行传输前进行Type2B信道接入；如果该上行传输机会的起始位置和下行传输机会的结束位置之间的空隙等于25μs或大于25μs，UE可以在该上行传输前进行Type2A信道接入。
另外，基站获得的COT内可以包括多个上下行转换点。当基站将自己获得的COT共享给UE进行上行传输后，在该COT内基站也可以使用Type2信道接入方式例如Type2A信道接入方式进行信道监听，并在信道监听成功后重新开始下行传输。图1给出了基站侧的COT共享的一个示例图。
当基站将获取的COT共享给UE传输上行时，COT共享的原则包括共享给UE传输的上行业务对应的信道接入优先级应不低于基站获取该COT时使用的信道接入优先级。在基站侧的COT共享过程中，一些信道接入方式下，上行传输机会的起始位置和下行传输机会的结束位置之间的空隙的大小还需要满足16μs或25μs的要求。上述COT共享的原则和空隙大小的要求都可以由基站来保证和指示，基站可以将共享COT内的信道接入方式通过显式或隐式的方式指示给UE。
基站可以通过联合编码的方式向UE显式指示延长循环前缀(Cyclic Prefix Extension，CPE)长度、信道接入方式或信道接入优先级等信道接入参数。
调度上行共享物理信道(Physical Uplink Shared Channel，PUSCH)传输的回退上行授权(下行控制信息(Downlink Control Information，DCI)格式0_0)：
调度PDSCH传输的回退下行授权(DCI格式1_0)；
调度PUSCH传输的非回退上行授权(DCI格式0_1)；
调度PDSCH传输的非回退下行授权(DCI格式1_1)。
基站还可以隐式指示COT内的信道接入方式。当UE收到基站发送的上行授权(Uplink grant，UL grant)、或下行授权(Downlink grant，DL grant)指示该PUSCH或、物理上行控制信道(Physical Uplink Control Channel，PUCCH)对应的信道接入类型为Type1信道接入时，如果UE能确定该PUSCH或PUCCH属于基站的COT内，例如UE收到基站发送的DCI格式2_0，并根据该DCI格式2_0确定该PUSCH或PUCCH属于基站的COT内，那么UE可以将该PUSCH或PUCCH对应的信道接入类型更新为Type2A信道接入而不再采用Type1信道接入。
4、UE侧的信道占用共享
当UE使用Type1信道接入发起COT后，除了可以将该COT内的资源用于上行传输，还可以将该COT内的资源共享给基站进行下行传输。在NR-U系统中，基站共享UE发起的COT包括两种情况，一种情况是基站共享调度的PUSCH的COT，另一种情况是基站共享免调度授权(Configured grant，CG)PUSCH的COT。
对于基站共享调度PUSCH的COT的情况，如果基站为UE配置了用于COT共享的能量检测门限，那么UE应使用该配置的用于COT共享的能量检测门限进行信道接入。由于在该情况下，UE的LBT接入参数和用于传输PUSCH的资源是基站指示的，因此，基站可以知道UE发起COT后该COT内可用的资源信息，从而在UE透明的情况下实现COT共享。
对于基站共享配置授权物理上行共享信道(Configured Grant Physical Uplink Shared Channel，CG PUSCH)的COT的情况，UE传输的CG-PUSCH中携带有CG-UCI(Uplink Control Information，上行控制信息)，CG-UCI中可以包括是否将UE获取的COT共享给基站的指示。如果基站为UE配置了用于COT共享的能量检测门限，那么UE应使用该配置的用于COT共享的能量检测门限进行信道接入。相应地，CG-UCI中的COT共享指示信息可以指示基站共享UE COT的起始位置、长度以及UE获取该COT时使用的不同的信道接入优先级(Channel access priority class，CAPC)信息。如果基站没有为UE配置用于COT共享的能量检测门限，那么CG-UCI中的COT共享指示信息包括1比特，用于指示基站可以共享或不能共享UE的COT。在没有被配置用于COT共享的能量检测门限下，基站可共享COT的起始位置是根据高层配置参数确定的，可共享的COT长度是预设的，以及基站仅可使用该共享的COT传输公共控制信息。
其中，侧行链路(Sidelink)传输，与非授权频谱(Unlicensed)的结合，一方面可以继承sidelink的基于无网络节点的通信方式，一方面也需要继承非授权频谱的LBT(listen before talk)机制。所以LBT机制中的COT共享机制对于sidelink同样适用，但蜂窝网络中相关上行和下行信道不再适用，sidelink中的信道不再分上下行。而且，Sidelink中的节点可能成为一个中继节点，即既有前传又有后传，按照简单地一对一的方式去执行LBT的话，可能需要做多次的LBT抢占不同信道的通信占用时间COT，才可以实现与不同的节点(如A-B，B-C)通信。综上，针对sidelink relay场景，存在COT共享方案的进一步优化的空间。原则上，指示共享COT的比例和位置的信令设计(CG-UCI)，可以与现有的NR-U系统设计保持一致。如图2所示，为现有技术中CG-PUSCH的COT共享的一个示意图。在图2所示中，给出了一种多个CG-UCI信令指示COT共享，并把共享的各COT叠加给另一个节点的示意图。
如图3A所示，为本发明实施例所应用的一个场景示意图。本发明实施例可以应用在至少两个设备节点之间进行通信的场景。在图3A所示中，以5个设备节点为例进行说明，设备节点E-设备节点A，设备节点A-设备节点B，设备节点B-设备节点C，设备节点C-设备节点D之间互相通信。每个设备节点在在第一信道接入发起信道占用时间COT时，可以将COT内的部分资源共享给其他设备节点进行通信。本发明中针对E-A，A-B，B-C，A-C，C-D的传输信道可以承载非授权频段上。可以应用于侧行链路场景、新无线场景，或，长期演进场景等。即可以基于网络A调度(mode1)下的资源配置(NR-U)，也可以是基于自主调度(mode2)下的资源配置(SL-U)，也可以是基于其他调度的资源配置，本发明实施例对此不做具体限定。设备节点可以包括手机、手表、耳机等设备。

下面以实施例的方式，对本发明技术方案做进一步的说明，如图4A所示，为本发明实施例中信道占用时间共享的方法的一个实施例示意图，可以包括：
401、第一设备节点获取第二设备节点共享的第一资源，所述第一资源为所述第二设备节点在第一信道接入发起信道占用时间COT时，所述COT内的部分资源。
可选的，所述第二设备节点为与所述第一设备节点直接通信或间接通信的设备节点。可以理解的是，直接通信可以理解为第一设备节点和第二设备节点之间的通信未通过其他设备节点通信，间接通信可以理解为第一设备节点和第二设备节点之间通过至少一个其他设备节点进行通信。
示例性的，结合图3A所示，假设第一设备节点是设备节点B，那么，第二设备节点可以是设备节点E，也可以是设备节点A。设备节点E可以认为是与设备节点B间接通信的设备节点，设备节点A可以认为是与设备节点B直接通信的设备节点。下面可以分情况分别进行说明：
(1)以第一设备节点为设备节点B，第二设备节点为设备节点E为例进行说明。设备节点E在第一信道接入发起信道占用时间COT时，可以将COT内的部分资源共享给设备节点A、设备节点B使用。其中，设备节点E共享给设备节点B的第一资源，是通过设备节 点A转发的。即由设备节点E进行配置COT的部分资源，配置好之后，共享给设备节点A和设备节点B进行通信。
(2)以第一设备节点为设备节点B，第二设备节点为设备节点A为例进行说明。设备节点E在第一信道接入发起信道占用时间COT时，可以将COT内的部分资源共享给设备节点A使用，设备节点A再将设备节点E共享给设备节点A的部分资源中的第一资源，再共享给设备节点B使用。即由设备节点E进行配置COT的部分资源，配置好之后，共享给设备节点A进行通信，但是，设备节点A可以进一步的将设备节点E配置给自己的部分资源再进行配置，配置好之后，共享给设备节点B进行通信。
(3)以第一设备节点为设备节点B，第二设备节点为设备节点A为例进行说明，设备节点A在第一信道接入发起信道占用时间COT时，可以将COT内的第一资源共享给设备节点B使用。即由设备节点A进行配置COT的部分资源，配置好之后，共享给设备节点B进行通信。
可选的，第一信道可以包括但不限于：物理侧行共享信道(Physical Sidelink Shared Channel，PSSCH)、物理侧行控制信道(Physical Sidelink Control Channel，PSCCH)、物理侧行广播信道(Physical Sidelink Broadcast Channel，PSBCH)、物理侧行反馈信道(Physical Sidelink Feedback Channel，PSFCH)。
示例性的，当设备节点A在侧行链路的信道(如PSSCH或PSCCH)接入发起COT后，除了可以将该COT内的资源用于向中继设备节点B的Sidelink传输，还可以将该COT内的资源共享给设备节点B进行sidelink回传、前传、广播、单播或组播。如图4B所示，为本发明实施例中第一设备节点和第二设备节点进行COT共享的一个示意图。在图4B所示中，设备节点A to设备节点B传输的设备节点A前传抢占的COT，共享给设备节点B回传(B to A)。
如图4C所示，为本发明实施例中第一设备节点和第二设备节点进行COT共享的另一个示意图。在图4C所示中，设备节点A to设备节点B传输的设备节点A前传抢占的COT，共享给设备节点B广播。
可选的，所述第一资源为所述COT内满足第一条件的部分资源，所述第一条件包括第一起始位置、第一时长和第一比例中的至少一项。
可选的，所述第一信道承载在非授权频段上。
可选的，所述发起信道占用时间的方式包括Type1信道接入方式。Type1信道接入方式主要用于通信设备发起信道占用。
可选的，所述COT为所述第二设备节点进行前传或回传的COT。
可选的，第一通信包括：回传、前传、广播、单播，或，组播中的至少一项。
可选的，所述回传的次数为至少一次，所述前传的次数为至少一次，所述广播的次数为至少一次，所述单播的次数为至少一次，所述组播的次数为至少一次。即COT sharing中允许在一个COT内有多个第一通信，第一通信也可以称为转换点。例如，在一个COT内有多个前传转换点，多个回传转换点，多个广播等。
可选的，所述第一资源通过无线资源控制(Radio Resource Control，RRC)、侧行控制信息(Sidelink Control Information，SCI)、上行控制信息(Uplink Control Information，UCI)、下行控制信息(Downlink Control Information，DCI)、或参考序列承载。
402、所述第一设备节点根据所述第一资源进行第一通信。
可选的，所述第一设备节点接收所述第二设备节点发送的所述第一通信的指示信息；所述第一设备节点根据所述第一资源，以及所述第一通信的指示信息，进行所述第一通信。
可选的，所述第一设备节点接收所述第二设备节点发送的所述第一通信的信道接入方 式；所述第一设备节点根据所述第一资源，以及所述第一通信的信道接入方式，进行所述第一通信。
可选的，所述第一设备节点接收所述第二设备节点发送的所述第一通信的指示信息，以及所述第一通信的信道接入方式；所述第一设备节点根据所述第一资源、所述第一通信的信道接入方式，以及所述第一通信的信道接入方式，进行所述第一通信。
可选的，第一通信的指示信息，是通过RRC、SCI、UCI、DCI、或参考序列承载的。
可选的，第一通信的信道接入方式，是通过RRC、SCI、UCI、DCI、或参考序列承载的。
需要说明的是，若第一通信为前传，那么，第一通信的指示信息、第一通信的信道接入方式，通常通过DCI、RRC，或SCI、参考序列承载的。若第一通信为回传，那么，第一通信的指示信息、第一通信的信道接入方式，通常通过UCI、RRC，或SCI、参考序列承载的。其中，第一资源、第一通信的指示信息和第一通信的接入方式，可以由第二设备节点配置。
可选的，第一通信的信道接入方式，也称为第一信道的共享接入方式或转换方式，可以包括但不限于：Type 2A、Type2B或Type2C方式。可以理解的是，COT sharing的信道接入方式(也可以称为转换方式)可以与NR-U系统保持一致(如Type2A/2B/2C)。Type2信道接入方式主要用于通信设备共享信道占用。其中，Type2C对应小于等于16us，Type2B对应16us，Type2A对应大于等于25us的转换时间。
需要说明的是，第一设备节点进行第一通信抢占的新COT，共享给第二设备节点，同样适用本发明实施例所述的方案。例如，设备节点B进行回传抢占的new COT，共享给设备节点A也同样适用。
在本发明实施例中，针对sidelink、新无线，LTE等在Unlicensed接入的场景，引入COT共享机制，实现COT共享，避免不同设备节点之间多次LBT，可以在一个COT内、实现更快速高效通信的目的。
403、第一设备节点向第三设备节点发送第二资源或第三资源。
可选的，在所述第一设备节点为中继节点的情况下，第一设备节点向第三设备节点发送第二资源或第三资源，可以包括但不限于以下的实现方式：
实现方式1：所述第一设备节点根据所述第一资源为第三设备节点配置第二资源；所述第一设备节点将所述第一资源中的所述第二资源，共享给所述第三设备节点，所述第二资源用于所述第三设备节点进行第二通信。即第二资源是第一设备节点先获取第二设备节点共享的第一资源，再根据该第一资源为第三设备节点配置的。
可选的，所述方法还包括：所述第一设备节点生成所述第二通信的指示信息；所述第一设备节点将所述第二通信的指示信息，向所述第三设备节点发送，所述第二通信的指示信息用于所述第三设备节点进行所述第二通信。
可选的，所述方法还包括：所述第一设备节点生成所述第二通信的信道接入方式；所述第一设备节点将所述第二通信的信道接入方式，向所述第三设备节点发送，所述第二通信的信道接入方式用于所述第三设备节点进行所述第二通信。
可以理解的是，第二通信的指示信息和第二通信的接入方式，是第一设备节点配置的。
可选的，第二资源为所述第一资源内满足第二条件的部分资源，所述第二条件包括第二起始位置、第二时长和第二比例中的至少一项。可以理解的是，第一设备节点可以将COT sharing进行二次分配，需要预先配置好预留给自己和下一设备节点的比例，即占比、还有相对起始位置、时长等，保证时序。
示例性的，当设备节点B在侧行链路的信道(如PSSCH或PSCCH)获取设备节点A共享的第一资源后，设备节点B可以预留第一资源的部分资源给自己用之外，还可以将一部分资源，即第二资源共享给设备节点C进行第二通信。
如图4D所示，为本发明实施例中第一设备节点、第二设备节点和第三设备节点进行COT共享的一个示意图。在图4D所示中，设备节点A to设备节点B传输中，设备节点A前传抢占的COT共享给中继设备节点B前传(B to C)，设备节点B可以进一步再共享给设备节点C来执行回传给设备节点B(C to B)。

可选的，所述方法还包括：所述第一设备节点接收所述第二设备节点发送的所述第三通信的指示信息；所述第一设备节点向所述第三设备节点发送第三通信的指示信息，所述第三通信的指示信息用于所述第三设备节点进行所述第三通信。

可以理解的是，sidelink relay场景中，每个节点自己独立配置UCI，可以更加灵活地指示给多个节点，这些节点之间是平行的。在CG-PUSCH传输且共享COT的情况下，终端设备应保证连续传输的多个CG-PUSCH中传输的CG-UCI中的COT共享指示信息指示相同起始位置和长度的COT共享。如果可以实现两级或两级以上的COT共享，那么sidelink节点之间不需要每次都去LBT，可以在一个COT内实现relay通信的目的。
可选的，第三设备节点可以是与第一设备节点直接通信或者间接通信的设备节点。
