Description

一种FBE的COT的共享方法及其装置 技术领域
本申请涉及通信技术领域，尤其涉及一种基于帧结构的设备FBE的信道占用时间COT的共享方法及其装置。
背景技术
在基于帧结构的设备(frame based equipment，FBE)信道接入模式中，目前可以由终端设备(user equipment，UE)自主开启信道占用时间(channel occupancy time，COT)，进行上行传输后将剩余的COT共享给基站(the next generation Node B，gNB)，并通过gNB的下行传输，将COT共享给其他UE进行上行传输，以提高FBE的信道接入效率。然而，这种共享方式会出现“固定帧周期(fixed frame period，FFP)参数混淆”和“无法收回信道使用权”的问题，使该共享方式无法正常运行，目前尚缺乏解决上述问题的有效手段。
发明内容
本申请实施例提供一种基于帧结构的设备FBE的信道占用时间COT的共享方法及其装置，通过向网络设备发送第一终端设备用于指示当前启用的COT所在FFP的指示信息，可以使网络设备向其他终端设备指示FFP的参数信息，从而使共享第一终端设备的COT的网络设备和第二终端设备可以根据FFP的参数信息对第一终端设备共享的COT进行占用，可以解决“FFP参数混淆”和“无法收回信道使用权”的问题。
第一方面，本申请实施例提供一种FBE的COT的共享方法，由第一终端设备执行，该方法包括：向网络设备发送所述第一终端设备用于指示当前启用的COT所在固定帧周期FFP的指示信息，其中，所述指示信息中至少包括所述FFP的参数信息。
申请实施例提供一种FBE的COT的共享方法，通过向网络设备发送第一终端设备用于指示当前启用的COT所在FFP的指示信息，可以使网络设备向其他终端设备指示FFP的参数信息，从而使共享第一终端设备的COT的网络设备和第二终端设备可以根据FFP的参数信息对第一终端设备共享的COT进行占用，可以解决“FFP参数混淆”和“无法收回信道使用权”的问题。
第二方面，本申请实施例提供一种FBE的COT的共享方法，由网络设备执行，该方法包括：接收第一终端设备发送的指示信息，其中，所述指示信息中至少包括所述第一终端设备当前启用的COT所在FFP的参数信息；向至少一个第二终端设备发送所述指示信息。
申请实施例提供一种FBE的COT的共享方法，接收第一终端设备发送的指示信息，向至少一个第二终端设备指示第一终端设备当前启用的COT所在FFP的参数信息，从而使共享第一终端设备的COT的网络设备和第二终端设备可以根据FFP的参数信息对第一终端设备共享的COT进行占用，可以解决“FFP参数混淆”和“无法收回信道使用权”的问题。
第三方面，本申请实施例提供一种FBE的COT的共享方法，由第二终端设备执行，该方法包括：获取网络设备发送的指示信息，其中，所述指示信息中至少包括第一终端设备当前启用的COT所在FFP的参数信息；基于所述指示信息，在所述当前启用的COT的共享COT片段内进行上行传输。
申请实施例提供一种FBE的COT的共享方法，通过获取网络设备发送的指示信息中的FFP的参数信息，基于指示信息，在当前启用的COT的共享COT片段内进行上行传输。第二终端设备可以根据指示的FFP的参数信息在第一终端设备共享的COT片段上进行上行传输，基于FFP的标识信息可以确定共享COT片段所在FFP属于第一终端设备，而非网络设备，可以解决“FFP参数混淆”的问题。而且根据COT的共享参数可以避免第二终端设备一直占用第一终端设备COT，进而能够使得第一终端设备可以及时收回信道使用权，解决了“无法收回信道使用权”的问题。

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申请相一致的所有实施方式。相反，它们仅是与如所附权利要求书中所详述的、本申请的一些方面相一致的装置和方法的例子。
为了便于理解，首先介绍本申请涉及的术语。
1、基于帧结构的设备(frame based equipment，FBE)
FBE为一种先听后说(listen before talk，LBT)信道接入模式，具有固定的帧结构。图1为FBE帧结构示意图，FBE帧结构由多个固定帧周期FFP构成。
2、固定帧周期(fixed frame period，FFP)
FFP为FBE帧结构的构成元素，如图1所示，FFP包括信道占用时间COT和空闲时间(idle period，IP)，空闲时间的最后9us是节点进行空闲信道评估(clear channel assessment，CCA)的时间。FFP长度可以被配置为1～10ms，在200ms内需保持配置值不能更改，1个FFP内COT的长度不能超过FFP长度的95％，IP的长度为Max{5％FFP，100us}。
3、信道占用时间(channel occupancy time，COT)
当CCA判定信道为空闲状态，终端设备或网络设备可以开启COT，并在COT内进行数据传输。
为了更好地理解本申请实施例公开的一种基于帧结构的设备FBE的信道占用时间COT的共享方法，下面首先对本申请实施例适用的通信系统进行描述。
请参见图2，图2为本申请实施例提供的一种通信系统的架构示意图。该通信系统可包括但不限于一个网络设备和一个终端设备，图2所示的设备数量和形态仅用于举例并不构成对本申请实施例的限定，实际应用中可以包括两个或两个以上的网络设备，两个或两个以上的终端设备。图2所示的通信系统以包括一个网络设备21和一个终端设备22为例。
需要说明的是，本申请实施例的技术方案可以应用于各种通信系统。例如：长期演进(long term evolution，LTE)系统、第五代(5th generation，5G)移动通信系统、5G新空口(new radio，NR)系统，或者其他未来的新型移动通信系统等。
本申请实施例中的网络设备21是网络侧的一种用于发射或接收信号的实体。例如，网络设备21可以为演进型基站(evolved NodeB，eNB)、传输点(transmission reception point，TRP)、NR系统中的下一代基站(next generation NodeB，gNB)、其他未来移动通信系统中的基站或无线保真(wireless fidelity，WiFi)系统中的接入节点等。本申请的实施例对网络设备所采用的具体技术和具体设备形态不做限定。本申请实施例提供的网络设备可以是由集中单元(central unit，CU)与分布式单元(distributed unit，DU)组成的，其中，CU也可以称为控制单元(control unit)，采用CU-DU的结构可以将网络设备，例如基站的协议层拆分开，部分协议层的功能放在CU集中控制，剩下部分或全部协议层的功能分布在DU中， 由CU集中控制DU。
本申请实施例中的终端设备22是用户侧的一种用于接收或发射信号的实体，如手机。终端设备也可以称为终端设备(terminal)、用户设备(user equipment，UE)、移动台(mobile station，MS)、移动终端设备(mobile terminal，MT)等。终端设备可以是具备通信功能的汽车、智能汽车、手机(mobile phone)、物联网设备如NB-IoT或(e)MTC、穿戴式设备、平板电脑(Pad)、带无线收发功能的电脑、虚拟现实(virtual reality，VR)终端设备、增强现实(augmented reality，AR)终端设备、工业控制(industrial control)中的无线终端设备、无人驾驶(self-driving)中的无线终端设备、远程手术(remote medical surgery)中的无线终端设备、智能电网(smart grid)中的无线终端设备、运输安全(transportation safety)中的无线终端设备、智慧城市(smart city)中的无线终端设备、智慧家庭(smart home)中的无线终端设备等等。本申请的实施例对终端设备所采用的具体技术和具体设备形态不做限定。
可以理解的是，本申请实施例描述的通信系统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，随着系统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。
可以理解的是，本申请实施例中的多个方案，既可以单独被实施，也可以组合在一起被实施，本申请并不对此作出限定。
下面结合附图对本申请所提供的基于帧结构的设备FBE的信道占用时间COT的共享方法及其装置进行详细地介绍。
图3为本申请一实施例的FBE的COT的共享方法的流程示意图，该方法应用于第一终端设备，如图3所示，该方法包括：
S31，向网络设备发送第一终端设备用于指示当前启用的COT所在FFP的指示信息，其中，指示信息中至少包括FFP的参数信息。
相关技术中终端设备可以自主开启FBE COT，并将终端设备自主开启的FBE COT共享给网络设备。基于这一特性，可以产生一种新的COT共享方式，即“以网络设备作为连接点的终端设备之间的FBE COT共享”。
所述FBECOT是指终端通过FBE的方式执行信道检测，并在信道检测通过后确定的信道占用时间。
本申请实施例中，第一终端设备(UE1)自主开启FBE COT，在COT进行上行传输后，可以将剩余的COT共享给网络设备，网络设备在共享COT上进行下行传输，第二终端设备(UE2)在检测到该下行传输后会误认为是网络设备开启的COT继而共享了第一终端设备开启的COT进行上行传输。
需要说明的是，第一终端设备为自主开启COT的终端设备，第二终端设备为共享了第一终端设备开启的COT的终端设备，第二终端设备至少有一个。
下图4中显示了一个具体的示例，UE2共享了UE1开启的COT(gNB作为连接点)在UE1的COT内完成了高优先级数据流量的发送，无需等待至下个FFP，降低了等待时延。然而，这种新的共享方式会出现“FFP参数混淆”和“无法收回信道使用权”的问题，使该共享方式无法正常运行。
其中，“FFP参数混淆”指第一终端设备自主开启COT时，第一终端设备的FFP起点位置和长度可与网络设备不同，第二终端设备会误将第一终端设备开启的COT当作网络设备开启的COT并进行共享，进而出现FFP参数混淆，错误地将共享COT所在的激活的FFP作为网络设备的FFP，具体示例可见图5。
“无法收回信道使用权”指当第一终端设备想要收回信道的使用权，再次进行上行传输时，信道可能仍然被第二终端设备所使用，导致第一终端设备无法使用，具体示例可见图6。
为了对上述COT的共享方法进行改善，本申请实施例中，第一终端设备自主开启COT后，向网络设备发送第一终端设备当前启用的COT所在FFP的指示信息。指示信息中包括FFP的参数信息，可选地，参数信息至少包括FFP的标识信息和/或当前启用的COT的共享参数。网络设备和第二终端设备可以根据指示信息中的FFP参数信息进行COT占用，避免“FFP参数混淆”和“无法收回信道使用权”的问题。
可选地，FFP的标识信息可以用于指示出该共享COT所在FFP是隶属于第一终端设备的，第二终端设备基于该FFP标识可以确定出共享COT为第一终端设备启用的COT，而非网络设备启用的COT， 从而通过该FFP标识信息解决“FFP参数混淆”的问题。
可选地，共享参数包括COT的共享起始位置和/或COT的共享时长。需要说明的是，共享起始位置用于指示第一终端设备的COT上允许被共享的起点，共享时长为第一终端设备的COT被允许共享的长度。

在一些实现中，携带FFP的参数信息的指示信息可以由第一终端设备通过信令单独发送给网络设备。在另一些实现中，携带FFP的参数信息的指示信息可以由第一终端设备通过上行传输同步发送给网络设备。例如，第一终端设备可以通过配置授权的上行控制信息(Configure Grant Uplink Control Information，CG-UCI)将指示信息发送给网络设备。
可选地，FFP的标识信息和COT的共享参数，可以同时携带在指示信息发送给网络设备，也可以FFP的标识信息和共享参数分别通过各自的指示信息上报给网络设备。

第二终端设备和网络设备需要基于该共享参数去共享第一终端设备允许共享的COT片段，超出共享参数所指示的COT部分将无法继续被网络设备和第二终端设备共享，即第一终端设备可以收回信道的使用权，进而可以通过共享参数解决“无法收回信道使用权”的问题。
本申请实施例提供的一种FBE的COT的共享方法，还包括以下步骤：
可选地，指示信息还包括COT共享指示，其中，COT共享指示用于指示是否对当前启用的COT进行共享。第一终端设备允许对当前启用的COT进行共享，则COT共享指示向网络设备指示出可以共享当前启用的COT。第一终端设备不允许对当前启用的COT进行共享，则COT共享指示向网络设备指示出不可以共享当前启用的COT。当然，也可以是根据通信协议或其他方式确定第一终端设备默认不允许对当前启用的COT进行共享，除非网络设备接收到明确的指示，才确定允许对当前启用的COT进行共享。当然，还可以是根据通信协议或其他方式确定第一终端设备默认允许对当前启用的COT进行共享，除非网络设备接收到明确的指示，才确定不允许对当前启用的COT进行共享。

作为一种可能的实现方式，在上行传输开始时，基于上行传输的时域资源占用情况，确定第一终端设备需要占用的COT片段，进而可以确定出剩余的COT片段，作为共享COT片段。作为另一种可能的实现方式，在上行传输结束时，确定后续还未使用的COT为剩余的COT片段，作为共享COT片段。

在本公开的所有实施例中，都可以采用默认的方式(例如通信协议或是预配置)确定共享起始位置和/或共享结束位置。例如：如果时域单元为symbol，则可以默认在剩余COT片段里面首个symbol作为网络设备下行传输的共享起始位置；如果时域单元为slot，则可以默认在剩余COT片段里面首个slot的首个symbol作为网路设备下行传输的共享起始位置。同样的，对于第二终端设备的共享起始位置也可以为默认位置。同时，网络设备的下行传输的共享起始位置和第二终端设备的共享起始位置，其先后顺序并不做出任何限定。例如，可以先进行网络设备的下行传输，然后再进行第二终端设备的传输；或采用其他顺序。而网络设备的下行传输的共享起始位置和第二终端设备的共享起始位置，既可以是相对于剩余COT片段的绝对位置，也可以是相对位置。例如，如果先进行网络设备的下行传输，则可以在网络设备的下行传输结束后的一个默认相对位置，作为第二终端设备的共享起始位置。再例如，如果先进行第二终端设备的共享传输，则可以结束后的一个默认相对位置，作为网络设备的下行传输的共享起始位置。又例如，可以在剩余COT片段预先确定好网络设备的下行传输和第二终端设备的共享传输的绝对位置。

举例说明，若网络设备的下行传输刚好占用全部的共享COT片段，则更新后的共享时长为0，指示第二终端设备不能共享，将信道还给第一终端设备。若网络设备的下行传输超过共享COT片段，则网络设备在超出共享COT片段后立刻停止下行传输，更新后的共享时长为0，指示第二终端设备不能共享，将信道还给第一终端设备。若网络设备的下行传输没有占用全部的共享COT片段，则根据共享时长与 占用时长的差值，确定更新后的共享时长，并根据占用信息中的所占用的传输时域单元，确定更新后的共享起始位置，指示第二终端设备在更新的共享时长和共享起始位置进行上行传输。
