实施例1
本申请实施例1提供一种无线链路检测方法，该方法可以由终端设备执行。
图2是本实施例的无线链路检测方法的一个示意图，如图2所示，该方法包括：
步骤201、当与无线链路监听相关的第一定时器超时时，终端设备确定使用未授权频段的无线链路失败；或者，当终端设备的高层接收到随机接入问题指示，且重建相关的第二定时器未运行时，该终端设备确定使用未授权频段的无线链路失败。
根据本实施例，能够针对使用未授权频段的无线链路进行无线链路失败检测。
在本实施例的步骤201中，终端设备可以在两种条件下，确定使用未授权频段的无线链路失败。第一种条件是与无线链路监听相关的第一定时器超时，第二种条件是终端设备的高层接收到随机接入问题指示，且重建相关的第二定时器未运行。
在本实施例中，终端设备根据该第一种条件，检测使用未授权频段的无线链路失败的过程例如可以是：
当终端设备的无线资源控制(RRC)层收到低层指示的一个特殊小区(该特殊小区例如是主小区(PCell)或主辅小区(PSCell))的一定数量(如连续N310，即，失步指示数量)个失步(Out Of Sync)指示时，启动一个定时器(例如第一定时器T310)，当该第一定时器超时(即，该第一定时器的运行时间超出作为阈值的持续时间)时，RRC确定无线链路失败。
此外，在该第一定时器T310的运行期间，如果RRC层收到该特殊小区的一定数量(如连续N311，即，同步指示数量)个同步(In Sync)指示时，可以停止该第一定时器。
在本实施例中，同步指示和失步指示是物理层无线链路监听的结果。当一个特殊小区的所有配置的无线链路监听(RLM)资源上的无线链路质量比阈值Q out差时，物理层在进行无线链路质量评估的帧内向高层上报失步指示。当一个特殊小区的任一配置的RLM资源上的无线链路质量比阈值Q in好时，物理层在进行无线链路质量评估的帧内向高层上报同步指示。
针对根据该第一种条件，检测使用未授权频段的无线链路失败的过程，本申请的发明人发现，在对使用未授权频段的无线链路进行失败检测时，与未授权频段相关的特殊机制有可能会对无线链路失败检测产生影响，例如：当使用未授权频段为终端设备提供服务时，网络设备和终端设备在进行通信前，都需要进行监听，即，对话前监听(Listen Before Talk，LBT)，从而确定信道是否空闲，只有当信道空闲时，网络设备才能发送同步块、参考信号、下行控制信息和下行数据等，因此，未授权频段的信道忙碌会对无线链路失败的检测产生干扰；同样的，未授权频段的信道忙碌会也会使终端设备在无线链路失败的检测和处理过程中受到影响。
在本实施例中，终端设备根据该第二种条件，检测使用未授权频段的无线链路失败的过程例如可以是：
当终端设备的上层没有收到随机接入响应，或者竞争解决未成功时，计数器PREAMBLE_TRANSMISSION_COUNTER的计数值加1，并且，当计数器PREAMBLE_TRANSMISSION_COUNTER的值为preambleTransMax+1时，向上层指示随机接入问题；并且，当高层接收到随机接入问题指示，且重建相关的第二定时 器(例如，T311)未运行时，该终端设备确定使用未授权频段的无线链路失败。
其中，终端设备的上层没有收到随机接入响应，例如是，在随机接入响应相关的窗口的窗长内没有收到正确的随机接入响应(RAR)等；竞争解决未成功，例如是，随机接入竞争解决相关的第三定时器的运行时间超过预设的持续时间等；preambleTransMax为用于控制向所述终端设备的高层发送随机接入问题指示的随机接入前导码的传输次数阈值。
针对根据该第二种条件，检测使用未授权频段的无线链路失败的过程，本申请的发明人也发现，在对使用未授权频段的无线链路进行失败检测时，与未授权频段相关的特殊机制有可能会对无线链路失败检测产生影响，例如：当使用未授权频段为终端设备提供服务时，网络设备和终端设备在进行通信前，都需要进行监听，即，对话前监听(Listen Before Talk，LBT)，从而确定信道是否空闲，只有当信道空闲时，网络设备才能发送随机接入响应或用于竞争解决的消息4，因此，未授权频段的信道忙碌会对无线链路失败的检测产生干扰；同样的，未授权频段的信道忙碌会也会使终端设备在无线链路失败的检测和处理过程中受到影响。
在本实施例中，如图2所示，该方法还可以包括：
步骤202、根据终端设备计测得到的信道负荷的参数，或者根据由网络设备提供的用于同步信号块和/或参考信号的发送情况的参数，对无线链路失败检测用的参数和/或对无线链路失败检测的过程进行调整。
在本实施例中，当在步骤202中对检测用的参数和/或检测的过程进行了调整的情况下，在步骤201中，终端设备可以根据调整后检测用的该参数和/或调整后的检测的过程，确定使用该未授权频段的无线链路失败。
在本实施例的步骤202中，该信道负荷的参数是指描述信道使用状态的参数。其中，信道负荷的参数包括下述参数中的至少一者：信道忙率(Channel busy ratio，CBR)、信道占有率(Channel occupancy ratio，CR)和对话前监听(LBT)成功率。
在本实施例中，信道忙率是指，第一预定时间段内预定信道被使用的时间占该第一预定时间段的比率。例如，信道盲率可以通过对配置的传输池里的资源的某个测量量进行测量，结果高于相应阈值的资源占总配置资源的比例，其中，该测量量例如可以是接收信号的强度指示(RSSI)。信道忙率可以是长期演进(LTE)中用于机器通信和/或车载通信的参数，也可以是新无线(NR)中为未授权频段引入的新的参数。
在本实施例中，信道占有率是指，第二预定时间段内(例如，当前子帧的前后共1000个子帧的时间)，预定信道中传输了或授权了的资源数占传输池里配置的资源总数的比例。信道占有率可以是LTE中用于未授权频段的参数，也可以是NR中为未授权频段引入的新的参数。
在本实施例中，对话前监听(LBT)成功率是指，第三预定时间段内对话前监听的成功次数占该第三预定时间段内全部对话前监听的次数的比例。
在本实施例的步骤202中，网络设备能够传输时，由网络设备提供的用于表示同步信号块和/或参考信号的发送情况的参数包括下述参数中的至少一者：
(1)网络设备和终端设置之间实际发送的同步信号块的信息，例如，同步信号块的周期、持续时间和在窗内的偏移量等；
(2)实际发送的参考信号和/或同步信号块(SSB)的偏移，例如，在支持RMTC、发现信号测量定时配置(DMTC)或SMTC窗外的传输的情况下，相较于之前配置的RMTC、DMTC或SMTC，实际发送的参考信号和/SSB发生的偏移；
(3)在第四预定时间段内由于LBT造成无法传输的数量或次数，该第四预定时间段例如可以是自上一次告知到当前时刻的时间段；
(4)由网络设备发送的信道负荷的参数，该信道负荷的参数的定义与前述相同，例如可以包括信道忙率(Channel busy ratio，CBR)、信道占有率(Channel occupancy ratio，CR)和对话前监听(LBT)成功率中的至少一者，并且，该信道负荷的参数例如可以由其它终端设备计测得出，发送给该网络设备，并由该网络设备发送给该终端设备；或者该信道负荷的参数可以由该网络设备自己得到，例如通过网络设备的测量，并由该网络设备发送给该终端设备。
在本实施例的步骤202中，被调整的所述无线链路失败检测用的参数，可以是在上述的根据第一种条件检测无线链路失败的过程中使用的参数，例如，包括下述参数中的至少一者：第一定时器(T310)的持续时间、使第一定时器(T310)启动的失步指示数量(N310)、使所述第一定时器(T310)停止的同步指示数量(N311)、用于检测快速无线链路失败(fast RLF)时的第四定时器(T312)的持续时间。
在该实施例中，调整在上述的根据第一种条件检测无线链路失败的过程中使用的参数，因此，即使在网络监听到信道忙碌的情况下，也能准确地检测无线链路失败；并且，只要测量结果达到上报指示，物理层总是上报失步指示，对物理层的变动较小。
下面，举例说明，基于信道负荷的参数对上述T310的持续时间、N310、N311、T312的持续时间的调整方式，例如：
在第一实施方式中，将失步指示数量调整为N310/(1-信道忙率)，即，当收到连续N310/(1-信道忙率)个失步指示时，启动第一定时器T310；
在第二实施方式中，将定时器T310的持续时间调整为配置值/(1-信道忙率)；
在第三实施方式中，如果支持快速无线链路失败(fast RLF)，定时器T312的持续时间被调整为配置值/(1-信道忙率)，其中，T310运行且对应的测量对象的测量报告触发时启动T312，一旦T312超时，立即发起连接重建过程；
在第四实施方式中，将同步指示数量调整为N311*(1-信道忙率)，即，当收到连续N311*(1-信道忙率)个失步指示时，停止定时器T310。
在上述举例中，如果N310/(1-信道忙率)，配置值/(1-信道忙率)或N311*(1-信道忙率)以及其他被调整的参数的参数值调整后不是整数，进行取整。
在上述举例中，信道负荷的参数以信道忙率为例，但不限于此，例如，也可以是信道占有率或LBT的成功率，如果使用信道占有率或LBT的成功率进行调整时，方法相反，即用乘法*代替上面的除法/，用除法/代替上面的乘法*，用信道占有率或LBT的成功率代替上面的(1-信道忙率)。
在上述举例中，进行参数的调整的步骤可以是强制的(mandatory)，也可以是可选的(optional)，例如，可以由网络设备配置、或终端设备自己决定。其中，由网络设备配置包括：网络设备直接配置其应用；或者，网络设备配置应用条件，终端判断满足条件后应用；或者，网络设备进行隐式配置等。
在本实施例中，网络设备直接配置可以使用高层信令、MAC CE和物理层控制信令的至少一种；网络设备配置应用条件的方法，例如可以是将某个测量量(如RSRP/RSRQ/SINR/信道占用比例等)的阈值指示给终端，当其测量结果高于或低于该阈值时，应用该方法进行参数调整；网络设备隐式配置，例如可以是网络设备配置终端设备使用未授权频段，由此，隐式配置终端设备可以根据信道负荷的参数，对所述无线链路失败检测用的参数进行调整。
在上述举例中，说明了基于信道负荷的参数进行调整的方法，基于网络设备提供的用于表示同步信号块和/或参考信号的发送情况的参数进行调整的方法，可以参考上述举例。
在本实施例的步骤202中，被调整的所述无线链路失败检测用的参数，也可以是在上述的根据第二种条件检测无线链路失败的过程中使用的参数，例如，包括下述参数中的至少一者：用于控制向所述终端设备的高层发送随机接入问题指示的随机接入前导码的传输次数阈值preambleTransMax、随机接入响应相关的窗口的窗长、随机接入竞争解决相关的第三定时器的持续时间。对上述参数的具体的调整方法，可以参照上述举例。
在本实施例中，通过对在上述的根据第二种条件检测无线链路失败的过程中使用的参数进行调整，能够提高在随机接入过程中无线链路失败的检测的准确性。
在本实施例的步骤202中，也可以对无线链路失败检测的过程进行调整。调整后的无线链路失败检测的过程可以包括下述步骤中的至少一者：
(1)失步指示数量达到用于启动所述第一定时器(T310)的失步指示数量(N310)时，不启动所述第一定时器(T310)，而是继续计数，直到达到第一指示数量(N313)时，启动所述第一定时器(T310)，其中，所述第一指示数量(N313)的数值根据所述由网络设备提供的用于同步信号块和/或参考信号的发送情况的参数确定；
(2)所述第一定时器(T310)未运行的情况下，挂起失步指示计数器，使用不同于所述失步指示计数器的第一计数器，当该第一计数器的计数值达到所述第一指示数量(N313)时，所述失步指示计数器恢复计数，其中，所述第一指示数量(N313)的数值根据所述由网络设备提供的用于同步信号块和/或参考信号的发送情况的参数确定；
(3)随机接入前导码的传输次数达到比阈值多1次时，所述终端设备的媒体访问控制(MAC)子层不向高层上报随机接入问题，而是继续对随机接入前导码的传输次数计数，直到计数达到第一数量N1时，向所述高层上报随机接入问题，该第一数量N1的数值根据所述由网络设备提供的用于同步信号块和/或参考信号的发送情况的参数确定；
(4)挂起随机接入前导码的传输次数的计数器，使用不同于所述随机接入前导码的传输次数的计数器的第二计数器，当该第二计数器达到第二数量(N2)时，随机接入前导码的传输次数计数器恢复计数，该第二数量的数值根据所述由网络设备提供的用于同步信号块和/或参考信号的发送情况的参数确定。
其中，在上述过程中所涉及的计数器，可以通过硬件的计数器实现，也可以由软 件程序实现。
在本实施例中，通过调整无线链路失败检测的过程，能够提高由物理层问题触发的无线链路失败的检测的准确性，和/或提高在随机接入过程中无线链路失败的检测的准确性。
在本实施例中，如图2所示，在该方法中，可以由步骤202a替代步骤202。
在该步骤202a中，终端设备的物理层向高层上报失步指示的触发条件可以被调整，由此，终端设备的物理层能够基于调整后的触发条件向高层上报失步指示，高层基于接收到的失步指示，根据无线链路失败检测用的参数，确定使用未授权频段的无线链路失败。由此，对物理层的行为做出改变，可以无需对高层的协议和实现作出改变。
在一个实施方式中，终端设备的物理层向高层上报失步指示的触发条件可以被调整为：物理层根据测量量与阈值组合中各阈值的关系，确定是否向所述终端设备的高层上报失步指示，其中，该阈值组合中可以具有至少2个阈值。例如，对同一个测量量，例如PDCCH BLER，SSB的RSRP/RSRQ/SINR/REEI，或者CSI-RS的RSRP/RSRQ/SINR/RSSI，可以使用2个阈值，当测量结果比第一阈值高或低，并且比第二阈值低或高时，向高层上报失步指示。
在另一个实施方式中，终端设备的物理层向高层上报失步指示的触发条件可以被调整为：根据信道负荷的参数与阈值的关系，确定是否向终端设备的高层上报失步指示，其中，该信道负荷的参数可以是信道忙率、信道占有率和对话前监听(LBT)成功率中的至少一者。对于该信道负荷的参数的说明可以参考前述的说明。在该实施方式中，例如，当同步信号块和/参考信号的质量比阈值1高或低，且信道忙率低于阈值2时，向高层上报失步指示；又例如，当同步信号块和/参考信号的质量比阈值1高或低，且信道占有率或LBT成功率高于阈值3时，向高层上报失步指示。
此外，步骤202a也可以不替代步骤202，由此，既进行参数和/或过程的调整，也进行触发条件的调整。
本申请的发明人进一步发现，在确定了使用未授权频段的无线链路失败时，如果使用当前机制(如小区选择、小区重选或失败上报等)进行处理，由于未授权频段特有的处理，如LBT等，可能导致在新建立连接的使用未授权频段的小区上还会发生无线链路失败。因此，考虑对当前机制进行调整。
下面，针对检测到使用未授权频段的无线链路失败时的处理进行说明。
在本实施例中，如图2所示，该方法还包括：
步骤203、当确定未授权频段上的无线链路失败发生在主小区组时，终端设备进行小区选择或小区重选。
在本实施例中，如果终端设备未被配置双连接(Dual Connectivity，DC)，或者，终端设备被配置了DC且无线链路失败发生在主小区组(MCG)，都可以认为无线链路失败发生在主小区组。这种情况下，终端设备可以留在连接态，选择一个合适的小区并进行连接重建，即，小区选择或小区选择后进行小区重选。如果确定无线链路失败后的一定时间内，未找到合适的小区，UE进入空闲态。
在步骤203中，终端设备进行小区选择时，可以采用如下方式中的至少一种：
(1)在小区选择的准则里，例如准则S，未授权频段使用第一阈值，该第一阈值与授权频段使用的第二阈值相同或不同，例如：网络设备通过***信息(例如SIB1)，提供给未授权频段特定的最小值，该特定的最小值是该第一阈值的一个举例，该特定的最小值例如可以是Qrxlevmin和/或Qqualmin，其中，Qrxlevmin是接收水平的最小值，即RSRP的最小接收值，Qqualmin是接收质量的最小值，即RSRQ的最小值。
(2)小区选择的准则(例如准则S)被与信道负荷相关的偏移值调整，该信道负荷例如是网络设备确定的信道负荷，例如，网络设备通过***信息(例如SIB1)提供该偏移值Qoffset load，基于该偏移值，准则S例如可以被调整为：
Srxlev＝Qrxlevmeas-(Qrxlevmin+Qrxlevoffset)-Pcompensation-Qoffset temp-Qoffset load
Squal＝Qqualmeas-(Qqualmin+Qqualoffset)-Qoffset temp-Qoffset load
(3)在小区选择的准则(例如准则S)里，使用与该信道负荷相关的测量量，该信道负荷例如是网络设备确定的信道负荷，该与该信道负荷相关的测量量可以被表示为Sload，基于该测量量Sload，准则S例如可以是：Srxlev＞0且Squal＞0且Sload＜0。
在一个实施方式中，该测量量Sload可以通过下式得到：
Sload＝Qloadmeas-(Qloadmax+Qloadmaxoffset)-Qoffset temp1
其中，Qloadmeas可以是某个小区的测量量中RSSI值高于阈值的测量量的比例；Qload可以是被配置的最大值；Qloadmaxoffset和Qoffset temp1可以是两个调整值。 Qloadmeas，Qloadmax，Qloadmaxoffset以及Qoffset temp1均为比值，无单位。
(4)在小区选择的准则里，使用网络设备确定的信道负荷相关的测量量的阈值和/或偏移值。
在步骤203中，终端设备进行小区重选时，可以采用如下方式中的至少一种：
(1)终端设备将未授权频段的优先级设置为低于授权频段的优先级；
(2)小区重选的准则被与信道负荷相关的偏移值调整，该信道负荷可以由网络设备确定，该小区重选的准则例如可以是对同频和优先级相同的异频小区的小区排序的R准则，例如，该与信道负荷相关的偏移值可以被表示为Qoffset load，R准则的邻区排序准则Rn被调整为Rn＝Q meas,n–Qoffset-Qoffset load；
(3)在小区重选的准则(例如R准则)里，使用与网络设备确定的信道负荷相关的测量量，关于该R准则中使用该测量量的说明，可以参考上述终端设备进行小区选择时的(3)中的说明；
(4)在小区重选的准则里，使用网络设备确定的信道负荷相关的测量量的阈值和/或偏移值。
在本实施例中，如图2所示，该方法还可以包括：
步骤204、当无线链路失败发生时，终端设备向网络设备发送信道负荷的参数，所述信道负荷的参数包括信道忙率、信道占有率、LBT成功率中的至少一者。
该信道负荷的参数可以包括：上一个服务小区的最后的负荷测量结果，和/或列出的小区的负荷测量结果。
其中，该上一个服务小区是指发生无线链路失败的小区或主小区，该负荷测量结果可以是小区级别的负荷相关的测量结果和/或SSB/CSI-RS级别的负荷相关的测量结果。
该信道负荷的参数的具体参数可以是信道忙率、信道占有率、LBT成功率中的至少一者，关于该该信道负荷的参数的说明可以参考上述步骤202中对于信道负荷的参数的说明。
在本实施例的步骤204的一个实施方式中，当使用未授权频段的无线链路失败发生时，在通过小区选择或小区重选重新建立连接后，如果终端设备有之前失败小区的信道负荷的参数，那么终端设备可以向网络侧报告之前失败小区的该信道负荷的参数。其中，该信道负荷的参数可以通过以下消息中的至少一者进行发送：无线资源控 制(RRC)连接重配完成消息、无线资源控制(RRC)连接重建完成消息、无线资源控制(RRC)连接回复完成消息、无线资源控制(RRC)连接建立完成消息、测量报告消息、终端设备信息响应消息。
在本实施例的步骤204的另一个实施方式中，当使用未授权频段的无线链路失败发生时，如果终端不需要连接重建，那么，终端设备可以向网络设备发送失败报告以报告该无线链路失败。其中，终端不需要连接重建的情况例如可以是：终端设备被配置了DC且无线链路失败发生在辅小区组；终端设备进行重复(duplication)传输，且进行duplication传输的其中一个小区发生链路失败。
