Description

无线链路监测方法、设备和存储介质 技术领域
本发明实施例涉及通信技术，尤其涉及一种无线链路监测方法、设备和存储介质。
背景技术
在移动通信中，基站与终端设备在无线载波上进行通信。在建立无线连接后，终端设备的物理层需要周期性的监测无线链路的质量。
目前，对于授权频谱，在具体的无线链路监测过程中，终端设备周期性的通过测量授权频谱上的参考信号的质量来实现对无线链路的监测。当测量的参考信号的质量低于预设门限时，则认定该无线链路处于失步(out-of-sync，OOS)状态，则物理层会向终端设备的高层(如无线资源控制(Radio Resource Control，RRC)层)发送失步(OOS)指示。当测量的参考信号的质量高于另一门限则认定该无线链路处于同步(in-sync，IS)状态，则物理层会向终端设备的高层(RRC层)发送同步(IS)指示。
在第五代的蜂窝移动通信(5th generation mobile networks，5G)中，同样会使用无线链路监测(Radio link monitoring，RLM)机制来检测下行无线链路的质量。由于5G通信系统将带宽划分为多个带宽部分(bandwidth part，BWP)，对于非授权频谱，BWP又可以包括多个先听后说(Listen Before Talk，LBT)子带，当网络设备仅通过部分子带传输了参考信号时，如何有效的对下行无线链路质量进行监测，是目前亟待解决的技术问题。

具体实施方式
为使本申请实施例的目的、技术方案和优点更加清楚，下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
本申请实施例的说明书、权利要求书及上述附图中的术语“第一”、“第二”等是用于区别类似的对象，而不必用于描述特定的顺序或先后次序。应该理解这样使用的数据在适当情况下可以互换，以便这里描述的本申请的实施例例如能够以除了在这里图示或描述的那些以外的顺序实施。此外，术语“包括”和“具有”以及他们的任何变形，意图在于覆盖不排他的包含，例如，包含了一系列步骤或单元的过程、方法、系统、产品或设备不必限于清楚地列出的那些步骤或单元，而是可包括没有清楚地列出的或对于这些过程、方法、产品或设备固有的其它步骤或单元。
以下，对本申请中的部分用语进行解释说明，以便于本领域技术人员理解。
1)带宽部分(bandwidth part，BWP)，是指信道带宽中的一部分，也可以叫做“载波带宽部分(carrier bandwidth part)”、“工作带宽(operating bandwidth)”或者传输带宽，本申请实施例中不对带宽部分的名称以及简称进行具体限定。BWP可以为频域上一段连续或非连续的资源。例如，一个带宽部分包含连续或非连续的K个子载波；或者，一个带宽部分为N个不重叠的连续或非连续的资源块(Resource Block)所在的频域资源；或者，一个带宽部分为M个不重叠的连续或非连续的资源块组(Resource Block Group，RBG)所在的频域资源，一个RBG包括P个连续的RB。另外，对于非授权频谱，一个带宽部分还可以包括Q个先听后说(Listen Before Talk，LBT)子带，其中，K、N、M、P和Q均为大于0的整数。
2)非授权频谱，通信设备需要遵循“先听后说(LBT)”原则，即通信设备在非授权频谱的信道上进行信号发送前，需要先进行信道侦听，只有当信道侦听结果为信道空闲时，该通信设备才能进行信号发送；如果通信设备在非授权频谱的信道上的信道侦听结果为信道忙，该通信设备不能进行信号发送。为了保证公平性，在一次传输中，通信设备使用非授权频谱的信道进行信号传输的时长不能超过最大信道占用时间(Maximum Channel Occupancy Time，MCOT)；为了避免在非授权频谱的信道上传输的信号的功率太大，影响该信道上的其他重要信号，例如雷达信号等的传输，通信设备使用非授权频谱的信道进行信号传输时需要遵循信号发射功率不超过最大发射功率和最大发射功率谱密度的限制。
在5G非授权频谱上，在系统载波带宽大于20MHz的宽带传输的场景下，终端设备可以被配置多个BWP且只激活一个BWP，当该激活的BWP包括多个LBT子带时，网络设备可以根据LBT子带的信道侦听结果，通过该激活的BWP包括的部分或全部LBT子带进行物理下行共享信道(Physical Downlink Shared Channel，PDSCH)的传输。图1为网络设备通过BWP0向终端设备发送数据的示意图，如图1所示，网络设备给终端设备配置的BWP0包括第一子带和第二子带两个LBT子带，网络设备可以通过调度第一子带和第二子带向终端设备传输PDSCH。然而，在每个LBT子带进行信道侦听时，第一子带LBT成功，也即处于空闲状态，第二子带LBT失败，也即处于忙碌状态，因此网络设备可以通过BWP0包括的第一子带向终端设备传输PDSCH。对于网络设备通过部分子带传输PDSCH的情况，如何有效的对下行无线链路质量进行监测，是目前需要解决的问题。
因此，本方案提出一种无线链路监测方法，通过确定待监测BWP，然后根据待监测BWP的多个子带中的至少一个子带上的目标无线链路监测-参考信号(Radio link monitoring-Reference Signal，RLM-RS)资源，对待监测BWP进行无线链路监测，其中，目标RLM-RS资源用于传输目标RLM-RS，由于根据至少一个子带上的目标RLM-RS资源，对待监测BWP进行无线链路监测，从而可以减少由于网络设备不能通过部分子带发送参考信号时对无线链路监测结果的影响，提高了无线链路监测的准确性。
下面对本申请提供的无线链路监测方法进行说明。

通常来说，传统的通信系统支持的连接数有限，也易于实现，然而，随着通信技术的发展，移动通信系统将不仅支持传统的通信，还将支持例如，设备到设备(Device to Device，D2D)通信，机器到机器(Machine to Machine，M2M)通信，机器类型通信(Machine Type Communication，MTC)，以及车辆间(Vehicle to Vehicle，V2V)通信等，本申请实施例也可以应用于这些通信系统。

本申请实施例的方法可以应用于非授权频谱的通信中，也可以应用于其它通信场景中，如授权频谱的通信场景。
非授权频谱是国家和地区划分的可用于无线电设备通信的频谱，该频谱可以被认为是共享频谱，即不同通信系统中的通信设备只要满足国家或地区在该频谱上设置的法规要求，就可以使用该频谱，可以不向政府申请专有的频谱授权。为了让使用非授权频谱进行无线通信的各个通信系统在该频谱上能够友好共存，通信设备在非授权频谱上进行通信时，可以遵循先听后说(Listen Before Talk，LBT)的原则，即，通信设备在非授权频谱的信道上进行信号发送前，需要先进行信道侦听(或称为信道检测)，只有当信道侦听结果为信道空闲时，通信设备才能进行信号发送；如果通信设备在非授权频谱的上进行信道侦听的结果为信道忙，则不能进行信号发送。可选地，LBT的带宽是20MHz，或为20MHz的整数倍。
本申请提供的无线链路监测方法包括：终端设备确定待监测BWP，该待监测BWP包括多个子带，然后终端设备再根据多个子带中的至少一个子带上的目标RLM-RS资源，对待监测BWP进行无线链路监测，其中，目标RLM-RS资源用于传输目标RLM-RS。由于终端设备可以根据多个子带中的至少一个子带上的RLM-RS资源，对待监测BWP进行监测，从而可以减少由于网络设备不能通过部分子 带发送参考信号时对无线链路监测结果的影响，提高了无线链路监测的准确性。
下面通过几个实施例，介绍终端设备根据多个子带中的至少一个子带上的RLM-RS资源，对待监测BWP进行无线链路监测的具体实现。
图3为本申请提供的无线链路监测方法的一种实现流程图，如图3所示，该方法包括以下步骤中的部分或全部：
S101：确定待监测BWP，该待监测BWP包括多个子带。
在本步骤中，终端设备在对无线链路进行监测时，首先需要确定待监测BWP。示例性的，该待监测BWP可以是终端设备在特殊小区上的激活BWP，或者，该待监测BWP可以是终端设备在特殊小区上的初始BWP。其中，特殊小区包括终端设备的主小区，或者特殊小区可以包括终端设备的主小区组中的主小区，或者，特殊小区包括终端设备的辅小区组中的主小区。
需要说明的是，初始BWP包括初始下行BWP，终端设备可以通过该初始下行BWP完成初始接入过程。
另外，待监测BWP包括多个子带，该子带可以为网络设备进行LBT时的LBT子带，也就是说，网络设备通过LBT子带向终端设备发送参考信号时，需要先侦听子带的状态，若子带处于空闲状态时，网络设备才能通过空闲的子带向终端设备发送参考信号。当然该子带也可以为根据其他方式确定的子带，本申请对此并不限定。
作为示例而非限定，子带的大小可以为20MHz，或为20MHz的整数倍。
可选地，终端设备在特殊小区上的激活BWP包括多个子带，终端设备在该特殊小区上的初始BWP包括一个子带，因此，终端设备确定该特殊小区上的待监测BWP为初始BWP。这主要是因为，当终端设备的激活BWP在频域上包括至少两个子带时，由于初始BWP只包括一个子带，可以限制无线链路监测RLM在初始BWP上进行，从而在RLM过程中减少频域部分子带不能发送时对RLM结果的影响。
S102：根据多个子带中的至少一个子带上的目标RLM-RS资源，对待监测BWP进行无线链路监测，目标RLM-RS资源用于传输目标RLM-RS。
在本步骤中，多个子带中可能会存在处于忙碌状态的子带，那么网络设备将不能通过这些处于忙碌状态的子带上的目标RLM-RS资源传输RLM-RS。为了减少由于网络设备不能通过部分子带传输RLM-RS，而对无线链路监测的监测结果带来的影响，终端设备需要从多个子带中确定出至少一个子带，从而可以根据至少一个子带上的目标RLM-RS资源，对待监测BWP进行无线链路监测。
可选地，上述的多个子带中的至少一个子带可以包括多个子带中传输目标RLM-RS的子带。
可选地，在本申请实施例中，对待监测BWP进行无线链路监测，包括：在失步评估周期内，评估目标RLM-RS资源上估计的下行无线链路质量是否低于失步门限；和/或，在同步评估周期内，评估目标RLM-RS资源上估计的下行无线链路质量是否高于同步门限。需要说明的是，对待监测BWP进行无线链路监测还可以包括其他的评估指标，例如评估目标RLM-RS资源上的目标RLM-RS是否传输等，本申请对此并不限定。
作为示例而非限定，在本方案中，至少一个子带包括在一个评估周期内，多个子带中实际传输了目标RLM-RS的子带。其中，由于目标RLM-RS资源可以是周期出现的，在一个评估周期内，目标RLM-RS资源可能会出现多次，因此，需要针对每个目标RLM-RS资源，独立的判断网络设备是否通过目标RLM-RS资源传输了目标RLM-RS。
应理解，一个评估周期可以是同步评估周期，也可以是失步评估周期，还可以是其他指标的评估周期，本申请对此并不限定。
应理解，在本申请实施例中的方案是针对一个目标RLM-RS资源来进行说明的。在实际应用时，终端设备可能被配置一个或多个目标RLM-RS资源来进行下行无线链路质量评估。当终端设备被配置多个目标RLM-RS资源来进行下行无线链路质量评估时，对于每个目标RLM-RS资源，均可以采用本申请中的方案。
可选地，当终端设备被配置多个目标RLM-RS资源来进行下行无线链路质量评估时，不同的目标RLM-RS资源可以对应不同的波束方向。
可选地，当终端设备被配置多个目标RLM-RS资源来进行下行无线链路质量评估时，不同的目标RLM-RS资源可以对应相同的波束方向。
可选地，上述的多个子带中的至少一个子带可以包括第一子带，该第一子带是多个子带中传输目标RLM-RS的子带中索引值最小的子带。
作为示例而非限定，在本方案中，第一子带为在一个评估周期内，多个子带中实际传输了目标 RLM-RS的子带中索引值最小的子带。例如：终端设备激活的待监测BWP0包括4个子带，分别为子带0、子带1、子带2和子带3。网络设备为BWP0配置的目标RLM-RS资源位于该4个子带中的每个子带上。在一个评估周期内，若网络设备只获得了部分子带的信道使用权，也即网络设备只能通过部分子带向终端设备发送目标RLM-RS。假设网络设备通过子带0、子带1和子带2上的目标RLM-RS资源向终端设备发送目标RLM-RS，那么第一子带即为子带0。又例如：终端设备激活的待监测BWP0包括4个子带，分别为子带0、子带1、子带2和子带3。网络设备为BWP0配置的目标RLM-RS资源位于该4个子带中的每个子带上，在一个评估周期内，目标RLM-RS资源在时域上出现S次。其中，在一个评估周期内，目标RLM-RS资源第i次(i＝0、1、2，。。。，S-1)出现的时刻，若网络设备只获得了部分子带的信道使用权，那么网络设备在该时刻只能通过部分子带向终端设备发送目标RLM-RS。假设在该时刻网络设备通过子带0、子带1和子带2上的目标RLM-RS资源向终端设备发送目标RLM-RS，那么在该时刻第一子带即为子带0。或者说，目标RLM-RS资源每次出现的时刻都可以对应一个第一子带，一个评估周期内，不同时刻对应的第一子带可以不同。
可选地，上述的多个子带中的至少一个子带可以包括第二子带，该第二子带是多个子带中传输目标RLM-RS的子带中索引值最大的子带。
作为示例而非限定，在本方案中，第二子带为在一个评估周期内，多个子带中实际传输了目标RLM-RS的子带中索引值最大的子带。例如：终端设备激活的待监测BWP0包括4个子带，分别为子带0、子带1、子带2和子带3。网络设备为BWP0配置的目标RLM-RS资源位于该4个子带中的每个子带上。在一个评估周期内，若网络设备只获得了部分子带的信道使用权，也即网络设备只能通过部分子带向终端设备发送目标RLM-RS。假设网络设备通过子带0、子带1和子带2上的目标RLM-RS资源向终端设备发送目标RLM-RS，那么第二子带即为子带2。又例如：终端设备激活的待监测BWP0包括4个子带，分别为子带0、子带1、子带2和子带3。网络设备为BWP0配置的目标RLM-RS资源位于该4个子带中的每个子带上，在一个评估周期内，目标RLM-RS资源在时域上出现S次。其中，在一个评估周期内，目标RLM-RS资源第i次(i＝0、1、2，。。。，S-1)出现的时刻，若网络设备只获得了部分子带的信道使用权，那么网络设备在该时刻只能通过部分子带向终端设备发送目标RLM-RS。假设在该时刻网络设备通过子带0、子带1和子带2上的目标RLM-RS资源向终端设备发送目标RLM-RS，那么在该时刻第二子带即为子带2。或者说，目标RLM-RS资源每次出现的时刻都可以对应一个第二子带，一个评估周期内，不同时刻对应的第二子带可以不同。
另外，网络设备和终端设备可以通过协商或协议约定的方式，例如网络设备向终端设备发送指示信息，以通知终端设备在第一子带还是第二子带上发送目标RLM-RS。
可选地，终端设备确定多个子带中传输目标RLM-RS的子带，或者，终端设备确定多个子带中传输目标RLM-RS的RLM-RS资源，具体可以包括以下两种方式：
第一种方式，多个子带中传输目标RLM-RS的子带是终端设备根据网络设备发送的指示信息确定的，该指示信息用于确定多个子带中实际进行目标RLM-RS传输的子带。
该多个子带中实际进行目标RLM-RS传输的子带，可以为该多个子带中，分配了RLM-RS资源，并且在该分配的RLM-RS资源上传输目标RLM-RS的子带。
作为示例而非限定，网络设备通过侦听的方式确定出多个子带中可以进行信号传输的子带后，可以向终端设备发送指示信息，该指示信息用于指示多个子带中实际进行信号传输的子带。对于终端设备来说，则接收网络设备发送的指示信息，并根据该指示信息，可以确定一段时间内网络设备实际进行信号传输的子带，如果RLM-RS资源属于该段时间内，那么终端设备可以从多个子带中确定至少一个实际进行了目标RLM-RS传输的子带。
举例来说，若待监测BWP中包括子带0、子带1、子带2和子带3，若网络设备经过侦听后，确定出子带0、子带1和子带2处于空闲状态，则网络设备会向终端设备发送指示信息，以使终端设备可以通过指示信息可以确定出子带0、子带1和子带2在第一时间段内为实际进行信号传输的子带。如果网络设备在子带0、子带1和子带2上配置的目标RLM-RS资源位于该第一时间段内，那么网络设备可以通过子带0、子带1和子带2传输目标RLM-RS，终端设备可以确定子带0、子带1和子带2为多个子带中实际进行目标RLM-RS传输的子带。
第二种方式，多个子带中传输目标RLM-RS的子带是终端设备根据参考信号盲检测的方式确定的。
作为示例而非限定，终端设备通过多个子带上的目标RLM-RS资源接收参考信号，并根据接收结果，从多个子带中确定传输目标RLM-RS的子带。
在该方案的具体实现中，针对多个子带中的每个子带来说，接收结果可以包括终端设备在某个子带上接收到了参考信号，或者终端设备在该子带上没有接收到参考信号。若终端设备在某个子带上接 收到了参考信号，则可以将该子带确定为传输了目标RLM-RS的子带，否则，该子带为未传输目标RLM-RS的子带。基于此，终端设备将可以通过参考信号盲检测(或者说，参考信号的存在性检测)的方式从多个子带中确定出传输目标RLM-RS的子带。
具体的，作为一个示例，网络设备可以为待监测BWP配置RLM-RS资源，其中，待监测BWP中存在至少一个子带被配置有RLM-RS资源。对于每个子带来说，终端设备通过该子带上的目标RLM-RS资源接收参考信号，并将接收到的参考信号和本地预设的参考信号序列做相关峰检测，若检测结果大于预设阈值，则终端设备确定在该子带上接收到了参考信号，否则，终端设备认为在该子带上没有接收到参考信号。
示例性的，上述的参考信号可以为目标RLM-RS。当然，也可以为其他参考信号，例如可以是解调参考信号(DeModulation Reference Signal，DMRS)，对于参考信号的具体形式，本申请实施例在此不做限制。
作为示例而非限定，终端设备接收网络设备发送的用于解调PDCCH的DMRS，并根据该PDCCH的DMRS的盲检测，可以确定一段时间内网络设备实际进行信号传输的子带，如果RLM-RS资源属于该段时间内，那么终端设备可以从多个子带中确定至少一个实际进行了目标RLM-RS传输的子带。
可以理解的是，在上述各方案中，目标RLM-RS资源包括传输目标RLM-RS的RLM-RS资源。
应理解，在本申请实施例中，一段时间内网络设备实际进行信号传输的子带，可以包括：在该段时间内，该网络设备占用的子带；传输目标RLM-RS的RLM-RS资源，可以包括：该目标RLM-RS资源中网络设备占用的子带和符号上的RLM-RS资源；未传输目标RLM-RS的RLM-RS资源，可以包括：该目标RLM-RS资源中网络设备没有占用的子带或没有占用的符号上的RLM-RS资源；网络设备获得信道使用权的资源，可以包括：网络设备占用的子带和符号上的资源；网络设备没有获得信道使用权的资源，可以包括：网络设备没有占用的子带或没有占用的符号上的资源。
具体地，无论至少一个子带包括多个子带中传输目标RLM-RS的子带，或者是包括第一子带，还是包括第二子带，至少一个子带均为实际传输了目标RLM-RS的子带，因此，至少一个子带上的目标RLM-RS资源，包括实际传输了目标RLM-RS的RLM-RS资源。
可选地，上述的多个子带中的至少一个子带可以包括多个子带中的每个子带。
具体地，至少一个子带可以包括多个子带中的每个子带。在这种方案中，终端设备将根据每个子带上的目标RLM-RS资源，对待监测BWP进行无线链路监测。
可选地，上述的多个子带中的至少一个子带可以包括第三子带，该第三子带是该多个子带中预设的子带。
具体地，至少一个子带可以是多个子带中预设的子带。示例性的，第三子带可以是与初始BWP包括相同频域资源的子带，也可以是多个子带中索引值最小的子带，还可以是多个子带中索引值最大的子带。例如，终端设备的待监测BWP包括子带0、1、2、3，终端设备的初始BWP包括子带2，那么第三子带为子带2。
可以理解的是，在至少一个子带包括多个子带中的每个子带，或者至少一个子带包括第三子带时，目标RLM-RS资源包括传输目标RLM-RS的RLM-RS资源，和/或，目标RLM-RS资源包括未传输目标RLM-RS的RLM-RS资源。
例如，在至少一个子带包括多个子带中的每个子带时，若每个子带都处于空闲状态，且网络设备通过每个子带上的目标RLM-RS资源均传输了目标RLM-RS，此时，至少一个子带上的目标RLM-RS资源为传输目标RLM-RS的RLM-RS资源；又例如，若存在部分子带处于空闲状态，部分子带处于忙碌状态，且网络设备通过处于空闲状态的子带上的目标RLM-RS资源传输了目标RLM-RS，此时，至少一个子带上的目标RLM-RS资源包括空闲子带上传输了目标RLM-RS的RLM-RS资源，和/或，忙碌子带上未传输目标RLM-RS的RLM-RS资源；又例如，若每个子带都处于忙碌状态，且网络设备未通过任何一个子带上的目标RLM-RS资源传输目标RLM-RS，此时，至少一个子带上的目标RLM-RS资源包括未传输目标RLM-RS的RLM-RS资源。
另外，在至少一个子带包括多个子带中预设的第三子带时，若第三子带处于空闲状态，且网络设备通过第三子带上的目标RLM-RS资源传输了目标RLM-RS，此时，至少一个子带上的目标RLM-RS资源为传输目标RLM-RS的RLM-RS资源；若存在部分第三子带处于空闲状态，部分第三子带处于忙碌状态，且网络设备通过处于空闲状态的第三子带上的目标RLM-RS资源传输了目标RLM-RS，此时，至少一个子带上的目标RLM-RS资源包括在空闲的第三子带上传输了目标RLM-RS的RLM-RS资源，和/或，在忙碌的第三子带上未传输目标RLM-RS的RLM-RS资源；若第三子带处于忙碌状态，且网络设备未通过任何一个第三子带上的目标RLM-RS资源传输目标RLM-RS，此时，至少一个子带上的目 标RLM-RS资源包括未传输目标RLM-RS的RLM-RS资源。
在一种可能的实现方式中，终端设备可以根据目标RLM-RS资源上的目标RLM-RS的盲检测，确定目标RLM-RS资源是传输目标RLM-RS的RLM-RS资源，或者是未传输目标RLM-RS的RLM-RS资源。
具体地，终端设备通过至少一个子带上的目标RLM-RS资源接收目标RLM-RS，若在某个目标RLM-RS资源上接收到了目标RLM-RS，则可以将该目标RLM-RS资源确定为传输目标RLM-RS的RLM-RS资源。若在某个目标RLM-RS资源上未接收到目标RLM-RS，则可以将该目标RLM-RS资源确定为未传输目标RLM-RS的RLM-RS资源。
可选地，终端设备根据多个子带中的至少一个子带上的目标RLM-RS资源，对待监测BWP进行无线链路监测，可以是根据多个子带中的一个子带上的目标RLM-RS资源，对待监测BWP进行无线链路监测，或者，也可以是根据多个子带中的至少两个子带上的目标RLM-RS资源，对待监测BWP进行无线链路监测。当然，还可以是根据多个子带中的每个子带上的目标RLM-RS资源，对待监测BWP进行无线链路监测。
在根据多个子带中的至少一个子带上的目标RLM-RS资源，对待监测BWP进行无线链路监测，可以包括如下过程：在失步评估周期内，评估至少一个子带上的目标RLM-RS资源上估计的下行无线链路质量是否低于失步门限；和/或，在同步评估周期内，评估至少一个子带上的目标RLM-RS资源上估计的下行无线链路质量是否高于同步门限。
其中，终端设备可以仅在失步评估周期内，评估至少一个子带上的目标RLM-RS资源上估计的下行无线链路质量是否低于失步门限，也可以仅在同步评估周期内，评估至少一个子带上的目标RLM-RS资源上估计的下行无线链路质量是否高于同步门限，还可以在失步评估周期内，评估至少一个子带上的目标RLM-RS资源上估计的下行无线链路质量是否低于失步门限，并且在同步评估周期内，评估至少一个子带上的目标RLM-RS资源上估计的下行无线链路质量是否高于同步门限。
可选地，同步门限和失步门限分别对应不同的块误码率(block error rate；BLER)值。可选地，同步门限或失步门限对应的BLER值是网络设备配置的。可选地，同步门限或失步门限是以一定PDCCH传输参数假设下得到的。可选地，一定PDCCH传输参数假设下可以得到同步门限对应的BLER值和SINR值。可选地，一定PDCCH传输参数假设下可以得到失步门限对应的BLER值和SINR值。
可选地，当RLM-RS资源包括不同的RS时，不同RS对应的同步门限或失步门限是独立确定的。例如，当RLM-RS资源包括CSI-RS资源时，CSI-RS资源对应第一同步门限或第一失步门限，当RLM-RS资源包括SSB资源时，SSB资源对应第二同步门限或第二失步门限。
可选地，在至少一个子带包括多个子带中传输目标RLM-RS的子带时，在失步评估周期内，终端设备可以根据所有传输了目标RLM-RS的子带上的目标RLM-RS资源估计下行无线链路质量是否低于失步门限，从而对待监测BWP进行无线链路监测。其中，终端设备可以通过至少一个子带上的目标RLM-RS资源接收目标RLM-RS，以估计下行无线链路质量。
作为示例而非限定，终端设备在评估周期内对待监测BWP进行无线链路监测可以包括如下实现方式。假设在评估周期内，用于监测无线链路质量的目标RLM-RS资源包括该至少一个子带中的每个子带上被配置出现至少一次的目标RLM-RS资源，其中，该目标RLM-RS资源包括传输目标RLM-RS的RLM-RS资源和/或未传输目标RLM-RS的RLM-RS资源。
作为示例而非限定，终端设备根据该至少一个子带中每个子带上出现至少一次的用于监测无线链路质量的目标RLM-RS资源，得到对应的信干噪比(Signal to Interference plus Noise Ratio；SINR)，并根据该SINR和预设的失步门限，确定该目标RLM-RS资源上传输的信号对应的块误码率(block error rate；BLER)是否低于失步门限，或，根据该SINR和预设的同步门限，确定该目标RLM-RS资源上传输的信号对应的BLER是否高于同步门限，从而确定该目标RLM-RS资源对应的无线链路质量，继而确定出整个待监测BWP的无线链路监测结果。示例性的，可以确定预设的失步门限对应的SINR，并确定该目标RLM-RS资源(或该目标RLM-RS资源上传输的信号)对应的SINR，是否大于该失步门限对应的SINR，若该目标RLM-RS资源对应的SINR高于该失步门限对应的SINR，则可确定该目标RLM-RS资源对应的BLER低于该失步门限；反之，若该目标RLM-RS资源对应的SINR低于该失步门限对应的SINR，则可确定该目标RLM-RS资源对应的BLER高于该失步门限。还可以确定预设的同步门限对应的SINR，并确定该目标RLM-RS资源对应的SINR，是否低于该同步门限对应的SINR，若该目标RLM-RS资源对应的SINR低于该同步门限对应的SINR，则可确定该目标RLM-RS资源对应的BLER高于该同步门限；反之，若该目标RLM-RS资源对应的SINR高于该同步门限对应的SINR，则可确定该目标RLM-RS资源对应的BLER低于该同步门限。
其中，评估周期可以为失步评估周期或者同步评估周期，也可以为其他指标的评估周期。
作为示例而非限定，终端设备在评估周期内评估无线链路质量，可以包括下述四种情况中的至少一种。同样地，假设在评估周期内，用于监测无线链路质量的目标RLM-RS资源包括该至少一个子带中的每个子带上被配置出现至少一次的目标RLM-RS资源，其中，该目标RLM-RS资源包括传输目标RLM-RS的RLM-RS资源和/或未传输目标RLM-RS的RLM-RS资源。
在第一种情况中，每个评估周期内，该至少一个子带中的每个子带上被配置出现至少一次的目标RLM-RS资源中每次出现的目标RLM-RS资源可对应一个SINR，根据该一个SINR可得到一个判断结果。因此，每个评估周期内，每次出现的目标RLM-RS资源对应一个判断结果。
在第二种情况下，每个评估周期内，该至少一个子带中的每个子带上，被配置出现至少一次的目标RLM-RS资源可对应一个SINR(例如对多次出现的目标RLM-RS资源上的信号检测进行平均或滤波)，即该至少一个子带中的每个子带对应一个SINR，根据该一个SINR可得到一个判断结果。因此，每个评估周期内，每个子带上的目标RLM-RS资源对应一个判断结果。
在第三种情况下，每个评估周期内，该至少一个子带中的每个子带上，目标RLM-RS资源被配置出现S次，对于每次出现目标RLM-RS资源的时刻，该至少一个子带可对应一个SINR(例如该至少一个子带中的每个子带上的目标RLM-RS资源上的信号检测进行平均或滤波)，根据该一个SINR可得到一个判断结果。因此，每个评估周期内，每次出现目标RLM-RS资源的时刻对应一个判断结果，评估周期内包括S个判断结果。
在第四种情况下，每个评估周期内，该至少一个子带中的所有目标RLM-RS资源可对应一个SINR(例如对每个子带上多次出现的目标RLM-RS资源上的信号检测进行平均或滤波)，该每个RLM-RS资源对应的一个SINR，根据该一个SINR可得到一个判断结果，因此，评估周期内包括一个判断结果。
可选地，在上述对多次出现的目标RLM-RS资源上的信号检测进行平均或滤波的过程中，对传输目标RLM-RS的多个RLM-RS资源上的信号检测进行平均或滤波，和/或，对未传输目标RLM-RS的多个RLM-RS资源上的信号检测进行平均或滤波。可选地，终端设备不对传输目标RLM-RS的RLM-RS资源上的信号检测和未传输目标RLM-RS的RLM-RS资源进行平均或滤波。
应理解，在上述几种情况中，判断结果包括：在失步评估周期内，评估至少一个子带上的目标RLM-RS资源上估计的下行无线链路质量是否低于失步门限，或者，在同步评估周期内，评估至少一个子带上的目标RLM-RS资源上估计的下行无线链路质量是否高于同步门限。
需要进行说明的是，上述方案中针对每个目标RLM-RS资源，均会判断估计的下行无线链路质量是否低于失步门限，在整个失步评估周期内，可能会出现多个目标RLM-RS资源的多个判断结果，也可能出现一个目标RLM-RS资源的多个判断结果(例如上述第一种情况、第二种情况和第三种情况)。可选地，在失步评估周期内，当所有的判断结果均为下行无线链路质量低于失步门限时，终端设备的物理层将会向高层上报失步指示。
需要进行说明的是，上述方案中针对每个目标RLM-RS资源，均会判断估计的下行无线链路质量是否高于同步门限，在整个同步评估周期内，可能会出现多个目标RLM-RS资源的多个判断结果，也可能出现一个目标RLM-RS资源的多个判断结果(例如上述第一种情况、第二种情况和第三种情况)。可选地，在同步评估周期内，只要存在判断结果为下行无线链路质量高于同步门限，终端设备的物理层将会向高层上报同步指示。
举例来说，图4a为BWP中子带和目标RLM-RS资源配置的示意图，图4b为传输目标RLM-RS的子带的一示意图，如图4a所示，终端设备激活的待监测BWP0包括4个子带，分别为子带0、子带1、子带2和子带3。网络设备为该终端设备的BWP0配置的RLM-RS资源位于该4个子带中的每个子带上。如图4b所示，在评估周期内，若网络设备只获得了部分子带的信道使用权，也即网络设备只能通过部分子带向终端设备发送目标RLM-RS。因此，网络设备将只在配置的RLM-RS资源中的部分RLM-RS资源上发送目标RLM-RS。终端设备将根据传输目标RLM-RS的子带上的目标RLM-RS资源估计下行无线链路质量。例如：网络设备只在子带1、子带2和子带3上配置的目标RLM-RS资源上发送目标RLM-RS，那么，终端设备也将根据子带1、子带2和子带3上的目标RLM-RS资源，估计下行无线链路质量。或者，终端设备将根据传输目标RLM-RS的目标RLM-RS资源估计下行无线链路质量。例如，终端设备将根据子带1上第1次和第2次(从0计数)出现的RLM-RS资源、子带2上的RLM-RS资源、子带3上第2次和第3次出现的RLM-RS资源，估计下行无线链路质量。
其中，若该评估周期为失步评估周期，终端设备可以根据上述的目标RLM-RS资源评估下行无线链路质量是否低于失步门限，或者，若该评估周期为同步评估周期，终端设备可以根据上述的目标RLM-RS资源评估下行无线链路质量是否高于同步门限。
示例性的，上述的失步门限对应的BLER为10％，同步门限对应的BLER可以为2％。
在上述方案中，终端设备根据多个子带中实际传输了目标RLM-RS的子带上的目标RLM-RS资源，或者根据多个子带中实际传输了目标RLM-RS的目标RLM-RS资源，来估计下行无线链路质量，并判断该下行无线链路质量是否低于失步门限或者是否高于同步门限，从而对待监测BWP进行无线链路的监测，可以减少由于网络设备不能通过BWP中部分子带发送目标RLM-RS时，对无线链路监测结果的影响，从而可以提高无线链路监测的准确性。
在一种实现方式中，终端设备可以通过第一子带、第二子带或者第三子带上的目标RLM-RS资源对待监测BWP进行无线链路的监测。例如，终端设备可以通过第一子带、第二子带或者第三子带上的目标RLM-RS资源接收目标RLM-RS，得到第一子带、第二子带或者第三子带上的目标RLM-RS对应的SINR，并根据该第一子带、第二子带或者第三子带上的目标RLM-RS对应的SINR和预设的评估门限，确定出第一子带、第二子带或者第三子带对应的无线链路质量，从而对待监测BWP进行无线链路监测。
举例来说，图4c为传输目标RLM-RS的子带的另一示意图，如图4c所示，终端设备激活的待监测BWP0包括4个子带，分别为子带0、子带1、子带2和子带3。网络设备为该终端设备的BWP0配置的RLM-RS资源位于该4个子带中的每个子带上。在评估周期内，若网络设备只获得了部分子带的信道使用权，也即网络设备只能通过部分子带向终端设备发送参考信号。因此，网络设备将只在配置的RLM-RS资源中的部分RLM-RS资源上发送目标RLM-RS，例如网络设备向终端设备发送目标RLM-RS的情况如图4b所示。作为示例，终端设备可以根据第一子带上的目标RLM-RS资源估计下行无线链路质量，其中，第一子带为多个子带中传输目标RLM-RS的子带中索引值最小的子带，如图4c所示。可选地，终端设备还可以根据第二子带或第三子带上的目标RLM-RS资源估计下行无线链路质量，其中，第二子带为多个子带中传输目标RLM-RS的子带中索引值最大的子带，第三子带是多个子带中预设的子带。
或者，第一子带、第二子带或第三子带是根据评估周期内每次出现的RLM-RS资源确定的。例如，在图4c中，评估周期内第0次出现的RLM-RS资源对应的第一子带是子带2，第1次出现的RLM-RS资源对应的第一子带是子带1，第2次出现的RLM-RS资源对应的第一子带是子带1，第3次出现的RLM-RS资源对应的第一子带是子带2。相应地，终端设备可以根据子带2上第0次和第3次出现的RLM-RS资源，以及子带1上第1次和第2次出现的RLM-RS资源，估计下行无线链路质量。
其中，若该评估周期为失步评估周期，终端设备可以根据上述的目标RLM-RS资源评估下行无线链路质量是否低于失步门限，或者，若该评估周期为同步评估周期，终端设备可以根据上述的目标RLM-RS资源评估下行无线链路质量是否高于同步门限。
示例性的，上述的失步门限对应的BLER为10％，同步门限对应的BLER可以为2％。
在上述方案中，终端设备根据第一子带、第二子带或者第三子带上的目标RLM-RS资源估计下行无线链路质量是否低于失步门限，或者判断是否高于同步门限，进而对待监测BWP进行无线链路的监测，可以减少由于网络设备不能通过BWP中部分子带发送目标RLM-RS时，对无线链路监测结果的影响，从而可以提高无线链路监测的准确性。
可选地，终端设备根据多个子带中的至少一个子带上的目标RLM-RS资源，对待监测BWP进行无线链路监测，还可以是针对每个子带独立的进行监测。在本方案中，针对至少一个子带中的一个子带(例如每个子带)，在失步评估周期内，评估每个子带上的目标RLM-RS资源上估计的每个子带上的下行无线链路质量是否低于失步门限；和/或，针对至少一个子带中的一个子带(例如每个子带)，在同步评估周期内，评估每个子带上的目标RLM-RS资源上估计的每个子带上的下行无线链路质量是否高于同步门限。
其中，针对至少一个子带中的每个子带，终端设备可以仅在失步评估周期内，评估每个子带上的目标RLM-RS资源上估计的每个子带上的下行无线链路质量是否低于失步门限，也可以仅在同步评估周期内，评估每个子带上的目标RLM-RS资源上估计的每个子带上的下行无线链路质量是否高于同步门限，还可以在失步评估周期内，评估每个子带上的目标RLM-RS资源上估计的每个子带上的下行无线链路质量是否低于失步门限，并且在同步评估周期内，评估每个子带上的目标RLM-RS资源上估计的每个子带上的下行无线链路质量是否高于同步门限。
作为示例而非限定，终端设备在评估周期内评估无线链路质量，可以包括下述两种情况中的至少一种。同样地，假设在评估周期内，用于监测无线链路质量的目标RLM-RS资源包括该至少一个子带中的每个子带上被配置出现至少一次的目标RLM-RS资源，其中，该目标RLM-RS资源包括传输目标RLM-RS的RLM-RS资源和/或未传输目标RLM-RS的RLM-RS资源。
在第一种情况中，每个评估周期内，该至少一个子带中的每个子带上被配置出现至少一次的目标RLM-RS资源中每次出现的目标RLM-RS资源可对应一个SINR，根据该一个SINR可得到一个判断结果。因此，每个评估周期内，每次出现的目标RLM-RS资源对应一个判断结果。
在第二种情况下，每个评估周期内，该至少一个子带中的每个子带上，被配置出现至少一次的目标RLM-RS资源可对应一个SINR(例如对多次出现的目标RLM-RS资源上的信号检测进行平均或滤波)，即该至少一个子带中的每个子带对应一个SINR，根据该一个SINR可得到一个判断结果。因此，每个评估周期内，每个子带上的目标RLM-RS资源对应一个判断结果。
可选地，在上述对多次出现的目标RLM-RS资源上的信号检测进行平均或滤波的过程中，对传输目标RLM-RS的多个RLM-RS资源上的信号检测进行平均或滤波，和/或，对未传输目标RLM-RS的多个RLM-RS资源上的信号检测进行平均或滤波。可选地，终端设备不对传输目标RLM-RS的RLM-RS资源上的信号检测和未传输目标RLM-RS的RLM-RS资源进行平均或滤波。
应理解，在上述两种情况中，判断结果包括：在失步评估周期内，评估至少一个子带中一个子带上的目标RLM-RS资源上估计的下行无线链路质量是否低于失步门限，或者，在同步评估周期内，评估至少一个子带中一个子带上的目标RLM-RS资源上估计的下行无线链路质量是否高于同步门限。
需要进行说明的是，上述方案中针对每个目标RLM-RS资源，均会判断估计的下行无线链路质量是否低于失步门限，在整个失步评估周期内至少一个子带中的一个子带上，可能会出现多个目标RLM-RS资源的多个判断结果，也可能出现一个目标RLM-RS资源的多个判断结果(例如上述第一种情况)。可选地，在失步评估周期内至少一个子带中某子带上，当所有的判断结果均为下行无线链路质量低于失步门限时，终端设备的物理层将会向高层上报该子带的失步指示。
需要进行说明的是，上述方案中针对每个目标RLM-RS资源，均会判断估计的下行无线链路质量是否高于同步门限，在整个同步评估周期内至少一个子带中的一个子带上，可能会出现多个目标RLM-RS资源的多个判断结果，也可能出现一个目标RLM-RS资源的多个判断结果(例如上述第一种情况)。可选地，在同步评估周期内至少一个子带中某子带上，只要存在判断结果为下行无线链路质量高于同步门限，终端设备的物理层将会向高层上报该子带的同步指示。
可选地，在本方案中，终端设备会在多个子带的每个子带上通过目标RLM-RS资源接收目标RLM-RS，若在某个子带上接收到目标RLM-RS，则根据接收到的目标RLM-RS确定该子带上的下行无线链路质量。例如，可以通过接收到的目标RLM-RS确定对应的SINR以及预设的失步门限，确定出该目标RLM-RS对应的BLER是否低于失步门限，或者，可以通过接收到的目标RLM-RS确定对应的SINR以及预设的同步门限，确定出该目标RLM-RS对应的BLER是否高于同步门限。可选地，若在某一时间段内，在某个子带上没有接收到目标RLM-RS，或者在某个子带上的上行链路(uplink；UL)的信道检测(例如LBT)持续失败，也即该子带处于忙碌状态时，则终端设备可以确定该子带处于无线链路失败(Radio link failure；RLF)的状态，或者说，终端设备的物理层将会向终端设备的高层上报该子带对应的失步指示。
可选地，可以针对每个子带独立的进行监测，并且根据是否在每个子带上接收到目标RLM-RS作为监测指标，对每个子带进行监测，在确定能够接收到目标RLM-RS后，再进一步地根据目标RLM-RS对应的SINR以及预设的失步门限或同步门限，确定该目标RLM-RS对应的BLER是否低于失步门限，或者是否高于失步门限，从而得到该子带的监测结果。
例如：图4d为子带的另一示意图，如图4d所示，终端设备激活的待监测BWP0包括4个子带，分别为子带0、子带1、子带2和子带3。网络设备能够进行目标RLM-RS传输的子带包括子带1、子带2和子带3，网络设备通过子带1、子带2和子带3上获得信道使用权的目标RLM-RS资源发送目标RLM-RS。对应的，终端设备在四个子带上接收目标RLM-RS，在预设时间段内，若终端设备可以在子带1、子带2和子带3上接收到目标RLM-RS，终端设备将分别根据各个子带上的目标RLM-RS，确定每个子带的目标RLM-RS对应的BLER是否低于失步门限，或者是否高于同步门限，从而得到每个子带的监测结果。另外，在预设时间段内，终端设备在子带0上没有接收到目标RLM-RS，或者在子带0上进行上行传输前的侦听过程中发现子带0的LBT处于持续失败的状态，则终端设备将可以认为子带0上的无线链路失败。
在上述方案中，终端设备通过对每个子带独立进行监测，并向终端设备上报每个子带的监测结果，可以使终端设备的高层更准确的获知每个子带上的信道状态。
可选地，在失步评估周期内，用于监测无线链路质量的目标RLM-RS资源包括传输目标RLM-RS的RLM-RS资源和未传输目标RLM-RS的RLM-RS资源。这主要是因为，在失步评估周期内，当终端设备测量得到某个RLM-RS资源上的下行无线链路质量差时，由于不确定该RLM-RS资源上的下行无 线链路质量差是因为网络设备没有进行RLM-RS发送还是真正的下行无线链路质量差，因此可以不区分该目标RLM-RS资源上是否有目标RLM-RS发送。
例如：如图4d所示，终端设备激活的待监测BWP0包括4个子带，分别为子带0、子带1、子带2和子带3。网络设备能够进行目标RLM-RS传输的子带包括子带1、子带2和子带3，网络设备通过子带1、子带2和子带3上获得信道使用权的目标RLM-RS资源发送目标RLM-RS。终端设备在进行BWP0上的无线链路监测时，将该失步评估周期内所有配置的目标RLM-RS资源，即包括未传输目标RLM-RS的RLM-RS资源和实际传输了目标RLM-RS的RLM-RS资源，用于进行无线链路质量的评估。其中，终端设备可以根据上述所有的目标RLM-RS资源评估下行无线链路质量是否低于失步门限。
示例性的，上述的失步门限对应的BLER为10％。
可选地，终端设备根据多个子带中的至少一个子带上的目标RLM-RS资源，对待监测BWP进行无线链路监测，还可以是在第一评估周期内，评估至少一个子带上的目标RLM-RS资源上估计的下行无线链路质量是否低于第一门限；和/或，针对至少一个子带中的每个子带，在第一评估周期内，评估每个子带上的目标RLM-RS资源上估计的每个子带上的下行无线链路质量是否低于第一门限，其中，该第一门限不同于失步门限。
其中，终端设备可以仅在第一评估周期内，评估至少一个子带上的目标RLM-RS资源上估计的下行无线链路质量是否低于第一门限，也可以仅在第一评估周期内，针对至少一个子带中的每个子带，评估每个子带上的目标RLM-RS资源上估计的每个子带上的下行无线链路质量是否低于第一门限，还可以在第一评估周期内，评估至少一个子带上的目标RLM-RS资源上估计的下行无线链路质量是否低于第一门限，并且在第一评估周期内，针对至少一个子带中的每个子带，评估每个子带上的目标RLM-RS资源上估计的每个子带上的下行无线链路质量是否低于第一门限。
具体地，第一评估周期可以是不同于同步评估周期和失步评估周期的周期，也可以是与同步评估周期相同的周期，还可以是与失步评估周期相同的周期。
其中，终端设备在第一评估周期内，终端设备评估至少一个子带上的目标RLM-RS资源上估计的下行无线链路质量是否低于第一门限，和/或，针对至少一个子带中的每个子带，在第一评估周期内，评估每个子带上的目标RLM-RS资源上估计的每个子带上的下行无线链路质量是否低于第一门限的方式，与上述各实施例中的判断方式类似，此处不再赘述。
另外，在终端设备在根据每个子带上的目标RLM-RS资源估计无线链路质量时，由于BWP的子带中可能会包括无法接收目标RLM-RS的子带，因此，对无线链路的监测结果会存在影响。为了解决这一问题，本实施例中可以将失步门限对应的BLER设置为与现有技术中10％不同的值。在一种实现方式中，可以将失步对应的BLER设置为不等于2％，且不等于10％的值。作为示例而非限定，可以将失步对应的BLER设置为大于10％的值。
在本方案中，由于根据第一门限对无线链路质量进行监测，因此可以有效的防止RLF的误报。
可选地，通过上述各实施例的描述可知，可选地，目标RLM-RS资源可以是第一RLM-RS资源中的资源，该第一RLM-RS资源是待监测BWP上配置的RLM-RS资源。
可选地，网络设备会为待监测BWP配置第一RLM-RS资源，该第一RLM-RS资源位于该待监测BWP的多个子带中的每个子带上，即该待监测BWP的多个子带中的每个子带上被配置的目标RLM-RS资源为该第一RLM-RS资源中位于该子带上的部分资源。
具体地，网络设备为待监测BWP配置第一RLM-RS资源，由于目标RLM-RS资源是在待监测BWP的多个子带中的至少一个子带上的RLM-RS资源，因此，目标RLM-RS资源可以是第一RLM-RS资源中的部分资源，也可以是第一RLM-RS资源中的全部资源，或者说，目标RLM-RS资源可以是第一RLM-RS资源中位于该多个子带中的至少一个子带上的资源。
可选地，在多个子带中的每个子带上均配置有RLM-RS资源，目标RLM-RS资源包括至少一个子带上配置的RLM-RS资源。
可选地，在多个子带中的每个子带上均配置有RLM-RS资源，该RLM-RS资源包括CSI-RS资源。进一步可选地，在多个子带中的每个子带上配置的CSI-RS资源可以是相同的CSI-RS资源，也可以是不同的CSI-RS资源。
可选地，在多个子带中的每个子带上均配置有RLM-RS资源，该RLM-RS资源包括SSB资源。
具体地，在待监测BWP的多个子带中的每个子带上，可以均配置RLM-RS资源，那么目标RLM-RS资源将包括至少一个子带上配置的RLM-RS资源。在一种可能的实现方式中，目标RLM-RS资源将包括每个子带上配置的RLM-RS资源。
在本申请实施例中，目标RLM-RS资源包括信道状态信息参考信号(Channel State Information  Reference Signal，CSI-RS)资源和/或同步信号块(Synchronization Signal/PBCH Block，SSB)资源。
具体地，在目标RLM-RS资源包括CSI-RS资源时，网络设备将会通过子带上的CSI-RS资源传输CSI-RS；在目标RLM-RS资源包括SSB资源时，网络设备将会通过子带上的SSB资源传输SSB；在目标RLM-RS资源包括CSI-RS资源和SSB资源时，网络设备将会分别通过子带上的CSI-RS资源传输CSI-RS，并通过子带上的SSB资源传输SSB。
本申请实施例提供的无线链路监测方法，通过确定待监测BWP，然后根据待监测BWP的多个子带中的至少一个子带上的目标RLM-RS资源，对待监测BWP进行无线链路监测，从而可以减少由于网络设备不能通过部分子带发送目标RLM-RS时对无线链路监测结果的影响，提高了无线链路监测的准确性。
下面，将对失步评估周期内，对下行无线链路质量是否低于失步门限，以及在非授权频谱下的失步门限的限定进行进一步介绍。
在失步评估周期内，评估被配置的RLM-RS资源上的下行无线链路质量是否低于失步门限，其中，该RLM-RS资源用于传输RLM-RS，该失步门限对应物理下行控制信道PDCCH传输参数，PDCCH传输参数包括第一能量比值，其中，第一能量比值包括PDCCH的资源单元(resource element，RE)的能量和RLM-RS的RE的能量的比值；和/或，第一能量比值包括PDCCH的DMRS的RE的能量和RLM-RS的RE的能量的比值。
应理解，为了避免在非授权频谱的信道上传输的信号的功率太大，影响该信道上的其他重要信号，例如雷达信号等的传输，通信设备使用非授权频谱的信道进行信号传输时需要遵循信号发射功率不超过最大发射功率和最大发射功率谱密度的限制。因此，对于失步门限对应的PDCCH传输参数假设中，考虑非授权频谱上的PDCCH的功率增强(power boosting)不合理，即PDCCH的RE的能量和RLM-RS的RE能量之间的比值假设为4dB，PDCCH的DMRS的RE能量和RLM-RS的RE能量之间的比值假设为4dB的是不合理的。
在本实施例中，在非授权频谱上的RLM过程中，对于失步门限对应的PDCCH传输参数假设中，上述的第一能量比值为0dB，也即PDCCH的RE的能量和RLM-RS的RE能量之间的比值假设为0dB，和/或，PDCCH的DMRS的RE能量和RLM-RS的RE能量之间的比值假设也为0dB。
可选地，失步门限对应的BLER大于10％。示例性的，该失步门限对应的BLER的取值可以为20％。可选地，失步门限对应的BLER的取值是根据仿真确定的。也就是说，如果终端设备没有被网络设备配置可以获得的失步门限的参数，那么可以通过表1所示的配置获得失步门限Q out和同步门限Q in分别对应的BLER out和BLER in。在表1中，作为示例而非限定，失步门限的取值为20％。
表1
配置 BLER out BLER in
0 20％ 2％
其中，RLM-RS资源包括CSI-RS资源和/或SSB资源。
具体地，在RLM-RS资源包括CSI-RS资源时，网络设备将会通过子带上的CSI-RS资源传输CSI-RS；在目标RLM-RS资源包括SSB资源时，网络设备将会通过子带上的SSB资源传输SSB；在目标RLM-RS资源包括CSI-RS资源和SSB资源时，网络设备将会分别通过子带上的CSI-RS资源传输CSI-RS，并通过子带上的SSB资源传输SSB。
本申请实施例提供的无线链路监测方法，在失步评估周期内，评估被配置的无线链路监测参考信号RLM-RS资源上的下行无线链路质量是否低于失步门限，该RLM-RS资源用于传输RLM-RS，失步门限对应物理下行控制信道PDCCH传输参数，该PDCCH传输参数包括第一能量比值。其中，第一能量比值为0dB，由此可以使得失步门限的设置更加合理，从而提高了无线链路监测的准确性。
