Description

通信方法及装置、网络设备、用户设备及存储介质 技术领域
本公开涉及非授权频谱应用技术，尤其涉及一种通信方法及装置、网络设备、用户设备(User Equipment，UE)及存储介质。
背景技术
随着无线频谱资源的不断紧张，非授权频谱的使用越来越普遍，在使用非授权频谱时，发送端在占用信道发送数据之前，一般需要对信道进行监听，也即空闲信道检测(Clear Channel Assessment，CCA)。如果信道空闲，则可以占用信道发送数据，其占用信道的最大时长(Maximum Channel Occupy Time，MCOT)由协议约定或者基站配置/指示；否则不能占用信道。这就是非授权频段上先听后说(Listen Before Talk，LBT)的信道接入方式。目前有两大类的LBT方式的设备，一种是LBE(Load Based Equipment)，只要设备有业务要发送，就可以随时进行信道监听，如果信道监听成功则可以在一段时间内持续占用信道发送数据；另一种是FBE(Frame Based Equipment)，此类设备是按照固定的周期来进行信道监听和数据发送。如果设备有数据待发送，需要等到周期的信道监听时刻到来才能去监听信道，如果信道监听成功，就可以在一段时间内持续占用信道发送数据。
但在高频频率范围内，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。所以在新空口(New Radio，NR)高频议题讨论中，已经确定了需要支持No-LBT的信道接入机制。也即，发射端在发送数据之前可以不需要进行LBT，而直接发送数据。现有的非授权频谱传输业务中，允许信道共享(COT sharing)的传输机制。也即终端或者基站在作为发起端，主动占用信道发送数据之后，可以将信道分享 给对端的接收端，使得接收端能利用该信道发送数据。如果终端采用了非先听后说No-LBT的方式作为发起端占用信道，终端将信道共享给基站后，基站应该采用什么LBT方式来占用信道并无涉及，这也是当前困扰非授权频谱使用的问题。

请参考图1，其示出了本公开实施例提供的一种无线通信系统的结构示意图。如图1所示，无线通信系统是基于蜂窝移动通信技术的通信系统，该无线通信系统可以包括：若干个终端11以及若干个基站12。
其中，终端11可以是指向用户提供语音和/或数据连通性的设备。终端11可以经无线接入网(Radio Access Network，RAN)与一个或多个核心网进行通信，终端11可以是物联网终端，如传感器设备、移动电话(或称为“蜂窝”电话)和具有物联网终端的计算机，例如，可以是固定式、便携式、袖珍式、手持式、计算机内置的或者车载的装置。例如，站(Station，STA)、订户单元(subscriber unit)、订户站(subscriber station)，移动站(mobile station)、移动台(mobile)、远程站(remote station)、接入点、远程终端(remote  terminal)、接入终端(access terminal)、用户装置(user terminal)、用户代理(user agent)、用户设备(user device)、或用户终端(user equipment，UE)。或者，终端11也可以是无人飞行器的设备。或者，终端11也可以是车载设备，比如，可以是具有无线通信功能的行车电脑，或者是外接行车电脑的无线通信设备。或者，终端11也可以是路边设备，比如，可以是具有无线通信功能的路灯、信号灯或者其它路边设备等。
基站12可以是无线通信系统中的网络侧设备。其中，该无线通信系统可以是第四代移动通信技术(the 4th generation mobile communication，4G)系统，又称长期演进(Long Term Evolution，LTE)系统；或者，该无线通信系统也可以是5G系统，又称新空口(new radio，NR)系统或5G NR系统。或者，该无线通信系统也可以是任一代系统。其中，5G系统中的接入网可以称为NG-RAN(New Generation-Radio Access Network，新一代无线接入网)。或者，MTC系统。
其中，基站12可以是4G系统中采用的演进型基站(eNB)。或者，基站12也可以是5G系统中采用集中分布式架构的基站(gNB)。当基站12采用集中分布式架构时，通常包括集中单元(Central Unit，CU)和至少两个分布单元(Distributed Unit，DU)。集中单元中设置有分组数据汇聚协议(Packet Data Convergence Protocol，PDCP)层、无线链路层控制协议(Radio Link Control，RLC)层、媒体访问控制(Media Access Control，MAC)层的协议栈；分布单元中设置有物理(Physical，PHY)层协议栈，本公开实施例对基站12的具体实现方式不加以限定。
基站12和终端11之间可以通过无线空口建立无线连接。在不同的实施方式中，该无线空口是基于第四代移动通信网络技术(4G)标准的无线空口；或者，该无线空口是基于第五代移动通信网络技术(5G)标准的无线空口，比如该无线空口是新空口；或者，该无线空口也可以是基于5G的 更下一代移动通信网络技术标准的无线空口。
在一些实施例中，终端11之间还可以建立E2E(End to End，端到端)连接。比如车联网通信(vehicle to everything，V2X)中的V2V(vehicle to vehicle，车对车)通信、V2I(vehicle to Infrastructure，车对路边设备)通信和V2P(vehicle to Pedestrian，车对人)通信等场景。
在一些实施例中，上述无线通信系统还可以包含网络管理设备13。
若干个基站12分别与网络管理设备13相连。其中，网络管理设备13可以是无线通信系统中的核心网设备，比如，该网络管理设备13可以是演进的数据分组核心网(Evolved Packet Core，EPC)中的移动性管理实体(Mobility Management Entity，MME)。或者，该网络管理设备也可以是其它的核心网设备，比如服务网关(Serving GateWay，SGW)、公用数据网网关(Public Data Network GateWay，PGW)、策略与计费规则功能单元(Policy and Charging Rules Function，PCRF)或者归属签约用户服务器(Home Subscriber Server，HSS)等。对于网络管理设备13的实现形态，本公开实施例不做限定。
本公开实施例涉及的执行主体包括但不限于：蜂窝移动通信系统中的用户设备(UE，User Equipment)，以及蜂窝移动通信的基站等。
图2是根据一示例性实施例示出的通信方法的流程示意图，如图2所示，本示例的通信方法适用于网络设备侧，这里的网络设备可以是基站、中继站、射频拉远等网络设备；本公开实施例的通信方法包括以下处理步骤：
步骤201，接收发送端在以No-LBT方式下占用非授权信道后发送的COT sharing指示信息。
本公开实施例中，发送端如果是网络设备如基站，则由于基站能够提前知道UE将在何时发送上行信息，因此，基站对非授权信道指示COT  sharing时，能清楚地知道下行发送结束的位置与UE上行开始的位置之间的间隙(gap)。另外，基站还能通过终端的信道状态信息(Channel State Information，CSI)上报流程评估UE侧的干扰情况，因而，基站可以为UE指示合适的信道接入方式，例如no LBT或者LBT，当为UE确定采用LBT方式使用非授权信道，还为UE确定LBT的具体参数，包括FBE还是LBE，以及在LBE信道接入方式下具体的LBE参数等。因此，当发送端为基站时，为通信对端即UE确定非授权信道的使用方式是容易实现的。
而当发送端是UE时，终端并不清楚基站将何时开始下行数据传输，也并不清楚基站侧的干扰情况。而本公开实施例是由基站来根据一定的规则确定自身使用COT sharing的非授权信道的LBT方式，而不需要UE为其指定LBT方式。
步骤202，响应于所述指示信息，确定共享的所述非授权信道的LBT使用方式。
在本公开实施例中，确定共享的所述非授权信道的LBT使用方式可以包括：确定下行数据传输的开始时间与所述发送端的上行数据传输结束时间之间的间隙小于或等于第一设定阈值，共享的所述非授权信道采用No-LBT方式进行下行数据传输；而确定下行数据传输的开始时间与所述发送端的上行数据传输结束时间之间的间隙大于或等于所述第一设定阈值，共享的所述非授权信道采用LBT方式进行下行数据传输。这里的第一设定阈值可以是200ms、500ms等。
作为一种实现方式，确定共享的所述非授权信道的LBT使用方式，也可以包括：检测干扰参数，确定所述干扰参数小于或等于第二设定阈值时，共享的所述非授权信道采用No-LBT方式进行下行数据传输；确定所述干扰参数大于或等于第二设定阈值时，共享的所述非授权信道采用LBT方式进行下行数据传输。这里的干扰参数可以是信噪比、发射功 率等参数对应的干扰参数，干扰参数是反映当前通信信道传输质量的指标，通过干扰参数可以确定信道的传输质量，基于传输质量来确定下行数据传输的信道使用情况，可以保证下行数据传输的传输质量，保证下行数据传输的准确性。
在本公开实施例中，所述检测干扰参数可以通过信道监听确定所述干扰参数。
在前述通信方法的步骤的基础上，本公开实施例的通信方法还包括：
基于网络配置确定LBT方式的通信参数；所述通信参数包括以下至少之一：LBT类型、信道接入优先级、信道占用最大时长。这里，可以根据网络通信协议中的相关规定来确定LBT方式的通信参数，当然，也可以由网络设备自身来确定上述LBT方式的通信参数，或者，由核心网向网络设备配置上述LBT方式的通信参数，并将上述LBT方式的通信参数向网络设备发送。
在本公开实施例中，当发送端是UE，并将非授权信道COT sharing给基站时，基站根据以下规则自行确定本基站占用信道的信道接入机制：
如果基站下行发送的开始时间与UE上行结束时间之间的gap小于或者等于一定门限值，则可以采用No-LBT方式使用非授权信道，否则，基站需要对UE共享的非授权信道进行LBT，并确定LBT的使用参数。而如果基站侧的干扰低于或者等于一定门限值时，则可以采用No-LBT方式使用非授权信道，否则，基站需要对UE共享的非授权信道进行LBT，并确定LBT的使用参数。
基站使用LBT的具体参数，具体包括LBT种类，信道接入优先级、信道占用最大时长等，可以在协议中约定，或者由基站自行配置。
基站可以通过信道监听过程确定基站侧的干扰大小。
本公开实施例中，当发送端采用No-LBT占用了非授权信道，且将非 授权信道共享给了网络设备后，网络设备需要重新确定发送端所共享的非授权信道的LBT使用方式，即网络设备需要根据当前的通信参数，重新为所共享的非授权信道确定使用No-LBT或LBT方式进行占用，以此来保证网络设备利用非授权信道传输下行数据的可靠性。本公开实施例保证了网络设备对非授权信道的占用方式，下行数据传输更可靠，提升了系统通信质量，以及非授权频谱下行数据传输的使用效益。
图3是根据一示例性实施例示出的通信方法的流程示意图，如图3所示，本公开实施例的通信方法包括以下处理步骤：
步骤301，以No-LBT方式占用非授权信道，向网络设备发送COT sharing指示信息。
本公开实施例中，当UE以No-LBT方式占用非授权信道的情况下，由于此时非授权信道的传输质量状况无法保证，因此，网络设备侧接收到针对非授权信道的COT sharing指示后，将确定UE所共享的非授权信道的使用方式。
步骤302，在所述非授权信道接收所述网络设备发送的下行数据。
当网络设备确定完UE所共享的非授权信道的使用方式，即采用LBT或No-LBT方式在非授权信道传输下行数据时，UE在该非授权信道接收网络设备发送的下行数据。
图4是根据一示例性实施例示出的通信装置的组成结构示意图，如图4所示，本公开实施例的通信装置可以应用于网络设备中，具体包括：
接收单元40，配置为接收发送端在以No-LBT方式下占用非授权信道后发送的COT sharing指示信息；
确定单元41，配置为响应于所述指示信息，确定共享的所述非授权信道的LBT使用方式。

确定下行数据传输的开始时间与所述发送端的上行数据传输结束时间之间的间隙小于或等于第一设定阈值，共享的所述非授权信道采用No-LBT方式进行下行数据传输。
在一些实施例中，所述确定单元41，还配置为：确定下行数据传输的开始时间与所述发送端的上行数据传输结束时间之间的间隙大于或等于所述第一设定阈值，共享的所述非授权信道采用LBT方式进行下行数据传输。

在一些实施例中，所述确定单元41，还配置为基于网络配置确定LBT方式的通信参数；所述通信参数包括以下至少之一：
LBT类型、信道接入优先级、信道占用最大时长。
