下面将结合附图,对本申请中的技术方案进行描述。

图1示例性地示出了一个网络设备和两个UE。可选地,该无线通信***100可以包括多个网络设备并且每个网络设备的覆盖范围内可以包括其它数量的终端设备,本申请实施例对此不做限定。可选地,该无线通信***100还可以包括网络控制器、移动管理实体等其他网络实体,本申请实施例对此不作限定。
应理解,本申请实施例的技术方案可以应用于各种通信***,例如:第五代(5th generation,5G)***或新无线(new radio,NR)、长期演进(long term evolution,LTE)***、LTE频分双工(frequency division duplex,FDD)***、LTE时分双工(time division duplex,TDD)等。本申请提供的技术方案还可以应用于未来的通信***,如第六代移动通信***,又如卫星通信***,等等。
本申请实施例中的UE也可称为终端设备、接入终端、用户单元、用户站、移动站、移动台(mobile station,MS)、移动终端(mobile Terminal,MT)、远方站、远程终端、移动设备、用户终端、终端、无线通信设备、用户代理或用户装置。本申请实施例中的UE可以是指向用户提供语音和/或数据连通性的设备,可以用于连接人、物和机,例如具有无线连接功能的手持式设备、车载设备等。本申请的实施例中的UE可以是手机(mobile phone)、平板电脑(Pad)、笔记本电脑、掌上电脑、移动互联网设备(mobile internet device,MID)、可穿戴设备,虚拟现实(virtual reality,VR)设备、增强现实(augmented reality,AR)设备、工业控制(industrial control)中的无线终端、无人驾驶(self driving)中的无线终端、远程手术(remote medical surgery)中的无线终端、智能电网(smart grid)中的无线终端、运输安全(transportation safety)中的无线终端、智慧城市(smart city)中的无线终端、智慧家庭(smart home)中的无线终端等。可选地,UE可以用于充当基站。例如,UE可以充当调度实体,其在V2X或D2D等中的UE之间提供侧行链路信号。比如,蜂窝电话和汽车利用侧行链路信号彼此通信。蜂窝电话和智能家居设备之间通信,而无需通过基站中继通信信号。
本申请实施例中的网络设备可以是用于与UE通信的设备,该网络设备也可以称为接入网设备或无线接入网设备,如网络设备可以是基站。本申请实施例中的网络设备可以是指将UE接入到无线网络的无线接入网(radio access network,RAN)节点(或设备)。基站可以广义的覆盖如下中的各种名称,或与如下名称进行替换,比如:节点B(NodeB)、演进型基站(evolved NodeB,eNB)、下一代基站(next generation NodeB,gNB)、中继站、接入点、传输点(transmitting and receiving point,TRP)、发射点(transmitting point,TP)、主站MeNB、辅站SeNB、多制式无线(MSR)节点、家庭基站、网络控制器、接入节点、无线节点、接入点(access piont,AP)、传输节点、收发节点、基带单元(base band unit,BBU)、射频拉远单元(Remote Radio Unit,RRU)、有源天线单元(active antenna unit,AAU)、射频头(remote radio head,RRH)、中心单元(central unit,CU)、分布式单元(distributed unit,DU)、定位节点等。基站可以是宏基站、微基站、中继节点、施主节点或类似物,或其组合。

还应理解,本申请中的网络设备和UE的全部或部分功能也可以通过在硬件上运行的软件功能来实现,或者通过平台(例如云平台)上实例化的虚拟化功能来实现。
某些通信***中支持终端设备之间的直接通信。例如,图1中的两个UE120之间也可以通过侧行链路(sidelink,SL)进行设备到设备的直接通信。侧行链路上的直接通信可以包括两种传输模式,模式1和模式2,具体如下:
模式1:终端设备的传输资源是由网络设备分配的,终端设备根据网络设备分配的资源在侧行链路上进行数据传输;网络设备可以为终端设备分配单次传输使用的资源,也可以为终端设备分配半静态传输的资源。
模式2:终端设备自主在资源池中选取资源,以在侧行链路上进行数据传输。
随着通信技术的发展,某些通信***中引入非授权(unlicensed)频段的先听后说(listen before talk,LBT),即终端设备在共享频谱信道(例如,该信道可以与无线保真(wireless fidelity,WIFI),蓝牙等其他***共享)上进行传输之前,需要先监听或感测该信道以确定该信道是否空闲,并且,终端设备只有在该信道空闲时才可以进行传输。
若终端设备监听该信道后确定该忙碌(非空闲),则可以认为此次侧行链路上的LBT失败(LBT failure)。如果LBT失败的次数达到预设次数(例如,LBT失败的次数达到10次),或者,如果发生LBT失败的时间满足预设时长(例如,自首次发生LBT失败开始,已持续10秒),则可以认为侧行链路发生LBT持续失败(LBT consistent failure)。
目前,尚不清楚在发生LBT持续失败时终端设备如何进行通信,可能会发生终端设备无法进行通信而导致业务中断的情况。
为了解决上述技术问题中的一个或多个,本申请提出一种通信方法及通信装置。下面结合图2对本申请实施例进行详细地举例说明。
图2是本申请实施例的通信方法的一个示意性流程图。应理解,图2示出了通信方法的步骤或操作,但这些步骤或操作仅是示例,本申请实施例还可以执行其他操作或者图2中的各个操作的变形,或者,并不是所有步骤都需要执行,或者,这些步骤可以按照其他顺序执行。图2所示的方法200可以包括步骤S210及S220,具体如下:
S210,终端设备向网络设备发送第一信息。
其中,所述第一信息可以用于指示侧行链路发生LBT持续失败。
所述第一信息还可以用于指示发生LBT持续失败的信道、发生LBT持续失败的业务和/或发生LBT持续失败的资源等。可选地,所述第一信息还可以包括LBT持续失败对应的第一参数,所述第一参数可以指示发生LBT持续失败的信道、发生LBT持续失败的业务和/或发生LBT持续失败的资源等。
例如,所述第一参数可以包括以下至少一项:资源池标识、目标地址标识、目标地址索引、带宽部分(bandwidth part,BWP)标识、载波标识、服务质量(quality of service,QoS)流(flow)标识、默认优先级(default priority)及逻辑信道(logical channel,LCH)优先级。
其中,所述第一参数中的资源池标识可以指示发生LBT持续失败的资源池;目标地址标识及目标地址索引可以指示因发生LBT持续失败而无法传输的目标地址,也就是说,终端设备进行该LBT就是为了向该目标地址传输数据;BWP标识可以指示发生LBT持续失败的BWP;载波标识可以指示发生LBT持续失败的载波;QoS流标识可以指示发生LBT持续失败的QoS流;默认优先级可以指示发生LBT持续失败的优先级;LCH优先级可以指示发生LBT持续失败的逻辑信道。
所述LBT持续失败可以包括多次LBT失败。例如,LBT持续失败可以包括n次LBT 失败,n为正整数。
在多次LBT失败中,每次发生LBT失败的信道、发生LBT失败的业务及发生LBT失败的资源等可以不同。
进一步地,所述第一信息还可以包括n组信息,所述n组信息分别指示n次LBT失败对应的第二参数,所述第二参数可以指示发生LBT失败的信道、发生LBT失败的业务和/或发生LBT失败的资源等。

其中,所述第二参数中的资源池标识可以指示发生LBT失败的资源池;目标地址标识及目标地址索引可以指示因发生LBT失败而无法传输的目标地址,也就是说,终端设备进行该次LBT就是为了向该目标地址传输数据;BWP标识可以指示发生LBT失败的BWP;载波标识可以指示发生LBT失败的载波;QoS流标识可以指示发生LBT失败的QoS流;默认优先级可以指示发生LBT失败的优先级;LCH优先级可以指示发生LBT失败的逻辑信道。
可选地,所述终端设备可以在发生LBT持续失败之前,向所述网络设备发送所述第一信息。这样,终端设备可以在预测可能或将要发生持续失败的情况下,就可以直接向网络设备上报侧行链路上的LBT持续失败(而不必等到发生LBT持续失败之后),以使网络设备可以提前为终端设备配置或指示侧行链路的辅助资源,从而能够避免业务中断,提升业务的连续性。
例如,若LBT失败的次数达到10次时,认为发生LBT持续失败,那么终端设备可以在发生6次LBT失败时,就提前向网络设备发送所述第一信息(上报LBT持续失败);或者,若LBT失败持续10秒,认为发生LBT持续失败,那么终端设备可以在LBT失败持续6秒时,就提前向网络设备发送所述第一信息。
可选地,所述第一信息还可以包括以下至少一项:首次发生LBT失败的时间、连续发生LBT失败的次数及预测信息。其中,所述预测信息可以用于预测是否会发生LBT持续失败。这样,网络设备可以根据这些信息,预测终端设备可能或将要发生持续失败,并提前为终端设备配置或指示辅助资源(而不必等到发生LBT持续失败之后),从而能够避免业务中断,提升业务的连续性。
可选地,在发生LBT失败的时间满足预设时长或连续发生LBT失败的次数满足预设次数的情况下,所述预测信息可以用于预测是否会发生LBT持续失败。
例如,若LBT失败的次数达到10次时,认为发生LBT持续失败,那么终端设备可以在发生8次LBT失败时,将所述预测信息设置为会发生LBT持续失败;或者,若LBT失败持续10秒,认为发生LBT持续失败,那么终端设备可以在LBT失败持续8秒时,,将所述预测信息设置为会发生LBT持续失败。
所述终端设备可以通过媒体接入控制层控制单元(media access control control element,MAC CE)或无线资源控制(radio resource control,RRC)消息向所述网络设备发送所述第一信息。
可选地,在终端设备通过MAC CE向网络设备发送所述第一信息时,所述第一信息可以包括n组信息,所述n组信息分别指示n次LBT失败对应的第二参数。例如,如图3所示,MAC CE可以包括MAC CE子头(subheader)及n组LBT失败指示,LBT失败指示1、LBT失败指示2、…LBT失败指示n,这n组LBT失败指示可以分别指示n次LBT失败对应的第二参数。
S220,所述网络设备向所述终端设备发送第二信息。
可选地,所述网络设备可以根据所述第一信息向所述比终端设备发送第二信息。可选地,网络设备在接收到所述第一信息之后,根据所述第一信息确定为终端设备配置或指示的辅助资源,并向所述比终端设备发送第二信息(指示该辅助资源)。
所述第二信息可以用于指示侧行链路的辅助资源,所述辅助资源可以用于所述终端设备进行侧行链路的业务传输。例如,终端设备可以使用辅助资源在侧行链路的授权频谱上进行业务传输。
所述辅助资源可以为动态资源、半静态资源或资源池。
可选地,所述辅助资源可以为所述网络设备通过下行控制信息(downlink control information,DCI)调度的动态资源。
可选地,所述辅助资源也可以为配置授权(configured grant,CG)资源。所述配置授权资源可以是网络设备通过RRC信令配置的。所述配置授权资源可以关联LBT持续失败对应的第一参数或LBT失败对应的第二参数。例如,当第一参数对应的资源(例如,关联目标地址ID的资源)发生LBT持续失败时,使用该配置授权资源;或者,当第二参数对应的资源(例如,资源池或BWP)发生LBT失败时,使用该配置授权资源。
可选地,所述配置授权资源可以为配置授权资源类型1或配置授权资源类型2。
可选地,所述辅助资源可以为资源池。其中,所述资源池可以关联LBT持续失败对应的第一参数或LBT失败对应的第二参数。例如,当第一参数对应的资源(例如,关联目标地址ID的资源)发生LBT持续失败时,使用该资源池;或者,当第二参数对应的资 源(例如,资源池或BWP)发生LBT失败时,使用该资源池。
可选地,所述资源池可以在预设时间段内有效。例如,网络设备可以为资源池配置计时器,终端设备可以在计时器超时前使用资源池中的资源;或者,终端设备可以接收到第二信息启动计时器,在计时器超时前使用资源池中的资源,此时,计时器可以是预先设定的。
所述方法200还可以包括步骤S230,具体如下:
S230,所述终端设备使用所述辅助资源进行侧行链路的业务传输。
在所述辅助资源为资源池的情况下,所述终端设备可以基于所述网络设备的调度,使用所述资源池中的资源进行侧行链路的业务传输。例如,网络设备可以通过DCI为终端设备调度资源池中的资源,以便终端设备在发生LBT持续失败时进行侧行链路的业务传输。
在所述辅助资源为资源池的情况下,所述终端设备可以自主选择所述资源池中的资源进行侧行链路的业务传输。例如,所述终端设备基于完全感知(full sensing)、部分感知(partial sensing)或随机选择(random selection)的方式,选择所述资源池中的资源进行侧行链路的业务传输。
所述方法200还可以包括步骤S240,具体如下:
S240,所述终端设备向所述网络设备发送第三信息。
其中,所述第三信息可以用于指示侧行链路的LBT持续失败恢复。例如,当终端设备发现侧行链路的LBT持续失败恢复时,可以向网络设备发送第三信息,以告知网络设备侧行链路的LBT持续失败恢复。
所述终端设备可以通过MAC CE或RRC消息向所述网络设备发送第三信息。
所述第三信息还可以指示LBT持续失败恢复的信道、LBT持续失败恢复的业务和/或LBT持续失败恢复的资源等。例如,所述第三信息还可以包括LBT持续失败对应的第一参数或LBT失败对应的第二参数。
所述方法200还可以包括步骤S250,具体如下:
S250,所述终端设备接收所述网络设备发送的第四信息。
其中,所述第四信息可以用于指示所述终端设备停止使用所述辅助资源。例如,网络设备可以在获知LBT持续失败恢复之后,指示所述终端设备停止使用所述辅助资源进行侧行链路的业务传输。
在本申请实施例中,终端设备向网络设备上报侧行链路上的LBT持续失败,并根据网络设备的指示使用辅助资源进行业务传输,可以使终端设备在发生LBT持续失败时继续进行侧行链路的业务传输,从而能够保证业务的连续性。
