相关申请的交叉引用
本申请要求在2020年02月21日提交中国专利局、申请号为202010108750.6、申请名称为“一种通信方法及装置”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及无线通信技术领域，特别涉及一种通信方法及装置。
背景技术
随着移动数据业务量的不断增长，频谱资源越来越紧张，仅使用授权频谱资源进行业务传输已经不能满足业务量需求，因此长期演进(Long Term Evolution，LTE)系统以及新无线(new radio，NR)系统等考虑在非授权频谱上进行业务传输。由于非授权频谱是共享的频谱，任何设备都可以使用，为了避免设备之间相互干扰，在使用非授权频谱进行业务传输之前，设备可以通过信道接入过程在非授权频谱中竞争信道。如果信道接入成功，那么可以通过非授权频谱进行数据传输，如果信道接入失败，那么就不能进行数据传输。
目前，终端侧设备处于无线资源控制空闲(idle)态或不活跃(inactive)态时，终端侧设备确定发生信道接入失败时，如何进行进一步处理，还没有明确的解决方案。
发明内容

具体实施方式
下面结合说明书附图对本申请实施例做详细描述。
本申请实施例可以应用于各种移动通信系统，例如：新无线(new radio，NR)系统、长期演进(long term evolution，LTE)系统、先进的长期演进(advanced long term evolution，LTE-A)系统、演进的长期演进(evolved long term evolution，eLTE)系统、未来通信系统等其它通信系统，具体的，在此不做限制。
本申请实施例中，“多个”是指两个或两个以上，鉴于此，本申请实施例中也可以将“多个”理解为“至少两个”。“至少一个”，可理解为一个或多个，例如理解为一个、两 个或更多个。例如，包括至少一个，是指包括一个、两个或更多个，而且不限制包括的是哪几个。例如，包括A、B和C中的至少一个，那么包括的可以是A、B、C、A和B、A和C、B和C、或A和B和C。同理，对于“至少一种”等描述的理解，也是类似的。“和/或”，描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B这三种情况。另外，字符“/”，如无特殊说明，一般表示前后关联对象是一种“或”的关系。
本申请实施例提及“第一”、“第二”等序数词用于对多个对象进行区分，不用于限定多个对象的顺序、时序、优先级或者重要程度，并且“第一”、“第二”的描述也并不限定对象一定不同。
本申请实施例中，终端侧设备，可以为具有无线收发功能的设备或可设置于任一设备中的芯片，也可以称为用户设备(user equipment，UE)、接入终端、用户单元、用户站、移动站、移动台、远方站、远程终端、移动设备、用户终端、无线通信设备、用户代理或用户装置。本申请实施例中的终端侧设备可以是手机(mobile phone)、平板电脑(Pad)、带无线收发功能的电脑、虚拟现实(virtual reality，VR)终端、增强现实(augmented reality，AR)终端、工业控制(industrial control)中的无线终端、无人驾驶(self driving)中的无线终端、远程医疗(remote medical)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)中的无线终端等等。
网络侧设备，可以是NR系统中的下一代基站(next Generation node B，gNB)，可以是LTE系统中的演进型基站(evolutional node B，eNB)等。
为便于理解本申请实施例，首先以图1中示出的通信系统为适用于本申请实施例的通信系统。图1示出了适用于本申请实施例的方法的通信系统的示意图。如图1所示，该通信系统包括网络侧设备和至少一个终端侧设备，为了描述方便，图1中只示出1个终端侧设备。
图1中，终端侧设备与网络侧设备可以通过授权频谱(也可以称为非共享频谱)进行通信，也可以通过非授权频谱(也可以称为共享频谱)进行通信。终端侧设备通过非授权频谱与网络侧设备进行通信之前，终端侧设备通过在非授权频谱中执行上行先听后说(listen Before Talk，LBT)，竞争信道。如果终端侧设备发生上行LBT失败，则可能继续执行上行LBT，直到竞争到信道。如果较多其他设备也在竞争信道，则可能一直发生连续上行LBT失败，此时终端侧设备不但不能完成信道接入，还会消耗大量资源，从而无法保证终端侧设备正常的业务传输。为此，本申请实施例提供一种方法，当终端侧设备在非授权频谱中，发生多次上行LBT失败时，以指示终端侧设备该如何处理。
需要说明的是，LBT，也可以称为信道接入过程，为了描述方便，以下均统一称为LBT。LBT的类型有两种：类型一，基于固定时长的LBT，终端侧设备如果在该固定时长内，在信道内检测到的信号的能量低于预设门限，则认为信道处于空闲状态，从而可以占用信道，否则需要重新竞争信道。
类型二，是基于回退机制的能量检测，终端侧设备随机选取一个值A，A为大于0的整数，检测到至少A个空闲的能量检测的时隙之后，才认为信道空闲，否则，认为信道忙碌。终端侧设备在认为信道空闲的时候，才可以占用信道进行数据传输。
对于类型一的LBT，在数据的传输起始点之前，如果固定时长的信号强度不满足空闲 条件，那么可以确定LBT失败。对于类型二的LBT，如果在数据传输起始点之前，还没有检测到至少A个空闲的能量检测的时隙，那么可以确定LBT失败。数据的传输起始点可以是指数据传输的起始时刻，例如数据在是一个时隙(slot)内进行传输，这个slot包括14个符号(符号0到13)，假如从符号0开始传输数据，如果在符号0，还没有检测到至少A个空闲的能量检测的时隙，那么可以确定发生LBT失败。
本申请实施例描述的网络架构以及业务场景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，随着网络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。
结合前面的描述，如图2所示，为本申请实施例提供的一种通信方法流程示意图。参见图2，该方法包括：
步骤201：终端侧设备在第一小区中执行上行LBT；
示例性的，步骤201中，终端侧设备的状态为无线资源控制(radio resource control，RRC)空闲(idle)态或者RRC不活跃(inactive)态。在RRC空闲态，为所述终端侧设备服务核心网的承载和接入网的数据承载都释放了，在RRC不活跃态，核心网的承载保留，但是接入网的某些数据承载释放了。
步骤201中，终端侧设备执行上行LBT之前，可以确定向网络侧设备发送上行数据。为了发送上行数据，终端侧设备可以在非授权频谱中，通过上行LBT竞争信道。终端侧设备执行上行LBT的具体流程，可以参考现有技术中的描述，在此不再赘述。
示例性的，在步骤201之前，网络侧设备可以向终端侧设备发送配置信息，所述配置信息可以包括以下一项或多项：
1、在多个小区中为终端侧设备配置的配置授权(configured grant，CG)或随机接入资源；
其中，configured grant可以包括物理上行共享信道(physical uplink shared channel，PUSCH)资源等内容，终端侧设备可以通过PUSCH资源向网络侧设备发送上行数据。configured grant包括的其它内容，在此不再赘述，具体可以参考现有技术中的描述。
2、在多个带宽部分(band width part，BWP)中为终端侧设备配置的配置授权(configured grant)或随机接入资源；
3、第三定时时长，以及第一计数值K，K为大于0的整数。
关于第三定时时长和第一计数值的具体作用，将在后面进行描述，在此不再赘述。
需要说明的是，网络侧设备具体如何发送配置信息，本申请实施例并不限定，例如网络侧设备可以通过无线资源控制(radio resource control，RRC)释放消息发送配置信息。
步骤202：当终端侧设备确定发生一致性LBT失败时，终端侧设备执行第一操作。
需要说明的是，发生一致性LBT失败，也可以称为“发生连续上行LBT失败”等，为了描述方便，以下均称为“发生一致性LBT失败”。
其中，第一操作包括以下至少一种操作：
1、执行小区重建立过程；
2、执行小区重选；
当处于RRC空闲态或者RRC不活跃态的终端侧设备驻留在一个小区后，随着终端侧设备的移动，终端侧设备可能需要更换到另一个更高优先级或更好信号的小区驻留，这就 是小区重选过程。小区选择是尽快找到一个合适小区的过程，小区重选是选择更适合小区的过程。
3、执行小区选择；
当终端侧设备开机或触发重建立过程等情况发生时，终端侧设备将执行小区搜索过程，并尽快选择合适的小区驻留，这个过程称为“小区选择”。
终端侧设备在小区搜索过程中会读取小区的系统信息，获取到Qrxlevmeas、Qrxlevmin和Qrxlevminoffset等参数，终端侧设备根据S准则评估该小区是否是合适的小区，一旦找到合适的小区(即满足S准则的小区)，则小区选择过程就完成了。如果该小区不是合适的小区，则终端侧设备继续进行搜索，直到找到合适的小区并驻留。
举例来说，S准则公式可以为：Srxlev>0且Squal>0，即小区的S值如果大于0，则说明该小区是合适的小区(适合驻留的小区)；
其中：Srxlev是指小区选择/重选过程中计算得到的电平值(dB)；Srxlev＝Qrxlevmeas–(Qrxlevmin+Qrxlevminoffset)–Pcompensation–Qoffsettemp；
Squal＝Qqualmeas–(Qqualmin+Qqualminoffset)–Qoffsettemp；
Qrxlevmeas是指终端侧设备测量得到的接收信号强度值，该值为测量到的参考信号接收功率(reference signal receiving power，RSRP)(dBm)；
Qrxlevmin是指该小区需要的最小接收信号强度值，该值在系统信息块1中指示；
Pcompensation为max(PEMAX–PUMAX，0)(dB)，其中PEMAX为终端在接入该小区时，系统设定的最大允许发送功率；PUMAX是指根据终端等级规定的最大输出功率，max为取最大值运算。
QrxlevminOffset只有正常驻留在一个访问公用陆地移动网(Visited Public Land Mobile Network，VPLMN)，周期性搜索一个高优先级的公用陆地移动网(Public Land Mobile Network，PLMN)进行小区选择评估时才有效，该参数对Qrxlevmin进行一定的偏置。
本申请实施例中，终端侧设备在小区选择或小区重选之前，可以先确定多个候选频点。所述多个候选频点可以为网络侧设备配置的，也可以根据其他方式确定的，本申请实施例对此并不限定。
终端侧设备根据确定的多个候选频点的频点优先级从高到低的顺序，优先选择频点优先级高的频点。需要说明的是，频点优先级可以是网络侧设备配置的，终端侧设备也可以根据实际情况对频点的频点优先级进行调整，具体怎么调整，本申请实施例对此并不限定。
终端侧设备选择一个频点之后，可以根据这个频点搜索小区。搜索到小区之后，在执行小区选择时，终端侧设备可以根据小区选择的规则，确定是否驻留该小区；在执行小区重选时，终端侧设备可以根据小区重选的规则，确定是否更换驻留小区。
4、确定不将所述第一小区作为小区重选或小区选择的候选小区；
示例性的，终端侧设备可以在第一时长内，确定不将所述第一小区作为小区重选或小区选择的候选小区。第一时长可以为网络侧设备配置的，也可以为通过其他方式确定的，比如通信协议规定的。第一时长的具体取值并不限定，例如可以为300毫秒(ms)。
举例来说，终端侧设备确定在第一小区中发生一致性LBT失败时，可以启动第一定时器，第一定时器的定时时长为第一时长。在第一定时器超时之前，终端侧设备确定不将所述第一小区作为小区重选或小区选择的候选小区。
进一步可选的，终端侧设备可以确定不将所述第一小区的同频小区作为小区重选或小区选择的候选小区。需说明的是，同频小区是指具有相同的中心频点相同的小区。
或者，终端侧设备可以在第一时长内，确定不将所述第一小区的同频小区作为小区重选或小区选择的候选小区。
上面的方法中，通过不将第一小区作为小区重选或小区选择的候选小区，可以避免终端侧设备在小区重选或小区选择时，再次驻留在第一小区中，提高驻留在信道质量较好的小区中的概率。
5、降低所述第一小区的频点的频点优先级，或者将所述第一小区的频点的频点优先级设置为最低优先级；
由于频点的频点优先级越高，终端侧设备会优先选择该频点，为此当终端侧设备在第一小区中发生一致性(consistent)LBT失败时，终端侧设备可以降低第一小区的频点的频点优先级。
终端侧设备可以每次将第一小区的频点的频点优先级降低至少一个级别，直至最低优先级；终端侧设备也可以直接将所述第一小区的频点的频点优先级降低为最低优先级，本申请实施例对此并不限定。
上面的方法中，通过降低第一小区的频点的频点优先级，可以降低终端侧设备在小区重选或小区选择时，再次驻留在第一小区中的概率，提高终端侧设备驻留在信道质量较好的小区中的概率。
6、确定所述第一小区对应的定时提前(timing advance，TA)失效；
由于第一小区发生一致性LBT失败，那么为了避免终端侧设备继续使用第一小区的配置授权向网络侧设备发送数据，此时可以确定第一小区的TA失效，从而达到节能省电的效果。终端侧设备可以停止第一小区对应的定时提前定时器。该定时器提前定时器是在之前接受到TA命令的时候启动的。
7、清除所述第一小区中所述终端侧设备对应的配置授权或专用的随机接入资源；
由于第一小区发生一致性LBT失败，那么为了避免终端侧设备继续使用第一小区的配置授权向网络侧设备发送数据，此时终端侧设备可以清除所述第一小区中所述终端侧设备对应的配置授权或专用的随机接入资源。
8、清除所述终端侧设备在所述第一小区中的无线网络临时标识(radio network temporary identity，RNTI)，所述RNTI用于调度重传；
由于第一小区发生一致性LBT失败，那么为了避免终端侧设备继续使用第一小区的配置授权向网络侧设备发送数据，此时终端侧设备可以清除所述终端侧设备在所述第一小区中的无线网络临时标识(radio network temporary identity，RNTI)。
9、执行条件切换(conditional handover，CHO)。
在单基站载波聚合或双连接的场景下，所述条件切换包括主小区的条件切换，以及主辅小区的条件变更或条件添加。
需要说明的是，在5G系统中，提出了一种切换技术，即CHO。现有的相关规定中，仅仅规范了CHO的基本流程：终端侧设备周期性上报测量结果，网络侧设备获取到终端侧设备上报的测量结果之后，网络侧设备可以向终端侧设备发送CHO配置信息。该CHO配置信息中可以包括CHO触发条件、一个或多个候选小区的信息(如，候选小区的小区全球标识(cell Global identifier，CGI)，候选小区的物理小区标识(physical-layer Cell identity， PCI)以及候选小区对应的频率信息)。其中，CHO触发条件用于指示终端侧设备在什么条件可以执行小区切换。终端侧设备在确定满足CHO触发条件时，执行小区切换。
本申请实施例中，CHO配置信息中的CHO触发条件可以包括：确定发生一致性(consistent)LBT失败。
终端侧设备在接收到CHO配置信息后，根据该CHO配置信息中的CHO触发条件确定发生一致性(consistent)LBT失败时，可以候选小区中选择一个小区作为目标小区，具体过程不再赘述。
本申请实施例中，终端侧如何确定发生一致性(consistent)LBT失败，可能存在多种方式。第一种可能的实现方式中，终端侧设备在第一小区中执行上行LBT之前，如果确定在第一小区中的初始BWP进行数据传输，那么在第二时长内，当所述终端侧设备在所述第一小区的初始BWP中发生上行LBT失败的次数大于或等于K时，所述终端侧设备可以确定发生一致性LBT失败，K为大于0的整数。
举例来说，终端侧设备确定在第一小区中的初始BWP进行数据传输时，可以在初始BWP中执行上行LBT。当终端侧设备确定在初始BWP中每发生一次上行LBT失败，可以执行以下操作：1、将计数器的计数值加1，其中计数器的初始值为0；2、启动或重启定时器，所述定时器的定时时长可以为第三定时时长，例如所述第三定时时长为网络侧设备通过配置信息配置的。
在定时器超时之前，如果计数器的计数值大于或等于K，则终端侧设备可以确定在第一小区中发生一致性LBT失败。在定时器超时的情况下，则说明本次LBT是成功的，终端侧设备可以重置计数器的计数值为0。
第二种可能的实现方式中，终端侧设备在第一小区中执行上行LBT之前，如果确定在第一小区中的N个BWP进行数据传输，那么在第二时长内，当所述终端侧设备在所述第一小区的N个BWP中的每个BWP中发生上行LBT失败的次数均大于或等于K时，所述终端侧设备可以确定发生一致性LBT失败数。
举例来说，终端侧设备可以为N个BWP中的每个BWP维护一个定时器以及计数器。针对任一BWP，当终端侧设备确定在该BWP中每发生一次上行LBT失败，可以执行以下操作：1、将该BWP对应的计数器的计数值加1，其中计数器的初始值为0；2、启动或重启该BWP对应的定时器，所述定时器的定时时长可以为第三定时时长，例如所述第三定时时长为网络侧设备通过配置信息配置的。
在定时器超时之前，如果计数器的计数值大于或等于K，则终端侧设备可以确定在该BWP中发生一致性LBT失败。则说明本次LBT是成功的，终端侧设备可以重置该BWP对应的计数器的计数值为0。
终端侧设备确定N个BWP中的每个BWP对应的定时器超时之前，每个BWP对应的计数器的计数值均大于或等于K的情况下，可以确定在第一小区中发生一致性LBT失败。
第三种可能的实现方式中，终端侧设备在第一小区中执行上行LBT之前，如果确定在包括所述第一小区的M个小区中进行数据传输，那么在第二时长内，所述终端侧设备确定在所述M个小区的每个小区中发生上行LBT失败的次数均大于或等于K时，所述终端侧设备可以确定发生一致性LBT失败。
第三种可能的实现方式的具体内容，可以参考第二种可能的实现方式中的描述，在此 不再赘述。
需要说明的是，本申请实施例中，在BWP或者小区中确定发生LBT失败，可以是指在这个BWP或小区中的任何上行传输的LBT失败，其中，上行传输的信道或信号包括但不限于PUSCH、物理随机接入信道(physical random access channel，PRACH)、物理上行控制信道(physical uplink control channel，PUCCH)以及探测参考信号(sounding reference signal，SRS)等。
通过上面的过程可知，终端侧设备确定发生一致性LBT失败时，通过执行第一操作，可以及时的恢复数据传输，解决了数据中断问题，提高数据传输的连续性，可靠性，降低数据传输时延。
进一步的，本申请实施例中，终端侧设备在第一小区中多次发生LBT失败时，可以向网络侧设备发送失败反馈信息；所述失败反馈信息包括所述第一小区的标识。
网络侧设备可以根据反馈信息进行网络优化，避免将终端侧设备配置在信道质量较差的小区，即避免将终端侧设备配置在多次发生LBT失败的小区进行配置授权传输中。或者，网络侧设备根据反馈信息确定第一小区容易发生连续LBT失败，那么不在第一小区中为终端侧设备配置CG，或将配置的CG的周期减小，从而补偿LBT失败。
可选的，所述失败反馈信息还包括所述终端侧设备在所述第一小区中发生一致性LBT失败中的LBT失败次数。这里的总次数，可以是指终端侧设备从接入第一小区的时刻到发送反馈信息的时刻的这段时长内，发生的一致性LBT失败中的LBT失败次数。
可选地，所述失败反馈信息可以通过RRC信令进行发送的。
本文中描述的各个实施例可以为独立的方案，也可以根据内在逻辑进行组合，这些方案都落入本申请的保护范围中。

本申请实施例中对模块的划分是示意性的，仅仅为一种逻辑功能划分，实际实现时可以有另外的划分方式。另外，在本申请各个实施例中的各功能模块可以集成在一个处理器中，也可以是单独物理存在，也可以两个或两个以上模块集成在一个模块中。上述集成的模块既可以采用硬件的形式实现，也可以采用软件功能模块的形式实现。
