具体实施方式
下面将结合本发明实施例中的附图，对本发明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发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
本申请的说明书和权利要求书中的术语“包括”以及它的任何变形，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。此外，说明书以及权利要求中使用“和/或”表示所连接对象的至少其中之一，例如A和/或B，表示包含单独A，单独B，以及A和B都存在三种情况。
在本发明实施例中，“示例性的”或者“例如”等词用于表示作例子、例证或说明。本发明实施例中被描述为“示例性的”或者“例如”的任何实施例或设计方案不应被解释为比其它实施例或设计方案更优选或更具优势。确切而言，使用“示例性的”或者“例如”等词旨在以具体方式呈现相关概念。
下面结合附图介绍本发明的实施例。本发明实施例提供的链路监测方法和终端可以应用于无线通信系统中。该无线通信系统可以为新空口(New Radio，NR)系统，或者其他系统，例如：演进型长期演进(Evolved Long Term Evolution，eLTE)系统或者长期演进(Long Term Evolution，LTE)系统，或者后续演进通信系统等。进一步，可以应用于上述无线通信系统中的非授权频段(Unlicensed Band)。
请参见图1，图1是本发明实施例可应用的一种网络系统的结构图，如图1所示，包括终端11和网络设备12，其中，终端11可以是用户终端(User Equipment，UE)或者其他终端侧设备，例如：手机、平板电脑(Tablet Personal Computer)、膝上型电脑(Laptop Computer)、个人数字助理(personal digital assistant，PDA)、移动上网装置(Mobile Internet Device，MID)、可穿戴式设备(Wearable Device)或者机器人等终端侧设备，需要说明的是，在本发明实施例中并不限定终端11的具体类型。上述网络设备12可以是4G基站，或者5G基站，或者以后版本的基站，或者其他通信系统中的基站，或者称之为节点B，演进节点B，或者传输接收点(Transmission Reception Point， TRP)，或者接入点(Access Point，AP)，或者所述领域中其他词汇，只要达到相同的技术效果，所述网络设备不限于特定技术词汇。另外，上述网络设备12可以是主节点(Master Node，MN)，或者辅节点(Secondary Node，SN)。需要说明的是，在本发明实施例中仅以5G基站为例，但是并不限定网络设备的具体类型。
进一步的，本发明实施例还可以应用于副链路(sidelink，或译为旁链路、侧链路、边链路、直接通信链路等)传输的场景，即终端之间可以直接进行数据传输的场景。
请参见图2，图2是本发明实施例提供的一种链路监测方法的流程图，该方法应用于终端，如图2所示，包括以下步骤：
步骤201、依据第一周期内是否存在监测对象，确定链路监测的行为，其中，所述行为包括以下至少一项；
上报链路质量信息、不上报链路质量信息、评估链路质量或者不评估链路质量。
其中，上述第一周期可以包括一个或者多个指示周期(indication period)，例如：第一周期为一个或者多个指示周期，或者第一周期为评估周期(evaluation period)，该评估周期内可以包括一个或者多个指示周期。其中，指示周期可以是用于监测对象监测的周期，或者称作用于发送监测对象的周期，但并不是表示所有指示周期内一定会存在监测对象。例如：指示周期为周期性发送RLM-RS的周期，但由于一些原因导致网络设备并没有在某一个或者多个指示周期内发送RLM-RS，从而这些指示周期内并不存在RLM-RS。另外，一个指示周期内可以配置用于监测一个或者多个监测对象。而评估周期可以是包括一个或者多个指示周期的周期。
例如：对于RLM，在没有配置非连续接收(Discontinuous Reception，DRX)的情况下，可以是指示周期T(Indication_interval)＝max(10ms,T RLM-RS,M)，其中T RLM-RS,M是所有配置的RLM-RS中的最小的周期。
对于RLM，在配置了DRS的情况下，当DRX周期长度小于等于320ms时，可以是指示周期T＝Max(10ms,1.5*DRX_cycle_length,1.5*T RLM-RS,M)，其中，DRX_cycle_length表示DRX周期长度；当DRX周期长度大于320ms 时，指示周期可以为DRX周期长度。当启动了T310计时器之后，终端可以按没有配置DRX的指示周期进行评估和上报。
又例如：对于BFD，在没有配置DRX的情况下，可以是指示周期T＝max(2ms,T BFD-RS,M)，其中T BFD-RS,M是所有配置的BFD-RS中的最小的周期。
对于BFD，在配置了DRS的情况下，当DRX周期长度小于等于320ms时，TIndication_interval＝Max(1.5*DRX_cycle_length,1.5*T BFD-RS,M)，当DRX周期长度大于320ms时，指示周期为DRX周期长度。
另外，本发明实施例中，指示周期也可以称为指示间隔(indication interval)。
需要说明的是，本发明实施例中，对指示周期和评估周期不作限定，例如：可以是协议中已定义的指示周期和评估周期，也可以是后续协议版本新定义的指示周期和评估周期。
上述第一周期内是否存在监测对象可以是，发送该监测对象的网络设备或者终端是否在该周期内有发送该监测对象。例如：在非授权频段，网络给终端配置了周期性发送的RLM-RS，由于网络侧在RLM-RS发送时刻之前做的信道侦听，判断信道在该发送时间无法被网络侧使用，导致网络配置某个时间点应该发送的RLM-RS实际上并没有发送，则该时间点对应的第一周期内不存在RLM-RS。又例如：由于sidelink存在非周期业务，进行非周期业务时，发送终端无法保证发送周期性的监测对象，从而导致一些第一周期内可能不存在监测对象；或者，sidelink终端需要通过感应(sensing)获取资源用于发送，因此获取的资源也存在时间的不确定性，因此监测对象的时间资源也存在不确定性，从而在sidelink中可能无法保证周期性地进行监测对象的发送，即一些第一周期内可能不存在监测对象。
上述依据第一周期内是否存在监测对象，确定链路监测的行为可以是，依据第一周期是否存在监测对象的结果，确定链路监测的行为。例如：第一周期内不存在监测对象，则可以确定不上报链路质量信息和/或不评估链路质量，或者第一周期内存在监测对象，则确定上报链路质量信息和/或评估链路质量。具体例如：第一周期内存在监测对象a，但不存在监测对象b，从而可以确定基于监测对象a的评估链路质量，以及上报链路质量信息，以及确定 不基于监测对象b的评估链路质量和上报链路质量信息，或者，第一周期内不存在任何监测对象，从而确定不上报链路质量信息和/或不评估链路质量。
需要说明的是，本发明实施例中，链路可以是非授权频段的无线链路或者sidelink频段的无线链路。
本发明实施例中，链路质量信息可以包括链路同步(in-sync，IS)或者失步(out-of-sync，OOS)，或者可以包括链路失败或者未失败，或者可以包括波束失败或者未失败等与链路质量相关的信息，进一步的，链路质量信息可以包括评估链路质量的评估结果。需要说明的是，本发明实施例中，对上报链路质量信息和评估链路质量不作限定，例如：可以采用协议中已定义的方式上报链路质量信息和评估链路质量，或者可以采用后续协议版本新引入的方式上报链路质量信息和评估链路质量。
本发明实施例中，通过上述步骤可以实现根据周期内是否存在监测对象的实际情况来确定链路监测的行为，从而可以提高终端的监测链路的能力，且进步还可以提高链路质量检测的精确度。
作为一种可选的实施方式，所述监测对象包括：
RLM的监测对象或者BFD的监测对象。
其中，RLM的监测对象可以包括如下至少一项：信道状态信息参考信号CSI-RS、同步信号块SSB、解调参考信号(Demodulation Reference Signal，DMRS)和混合自动重传请求(Hybrid Automatic Repeat Request，HARQ)信息。上述CSI-RS、SSB或DMRS可以称为RLM-RS。
而上述BFD的监测对象可以包括如下至少一项：CSI-RS、SSB、DMRS和HARQ信息。上述CSI-RS、SSB或DMRS可以称为BFD-RS。
其中，上述DMRS可以是物理副链路反馈信道(physical sidelink feedback channel，PSFCH)的DMRS，上述HARQ信息也可以是PSFCH的HARQ信息。当然，也可以是物理下行控制信道(Physical downlink control channel，PDCCH)，或者物理下行共享信道(Physical downlink shared channel，PDSCH)的DMRS或者HARQ信息。
需要说明的是，本发明实施例中上述RLM的监测对象可以包括一个或者多个监测对象，例如：RLM-RS包括可以包括一个或者多个信道状态信息参 考信号(Channel-state information reference signal，CSI-RS)和/或一个或者多个同步信号块(Synchronization signal Block，SSB)，而BFD-RS也可以包括一个或者多个CSI-RS和/或一个或者多个SSB；当然，也可以是，上述RLM的监测对象包括RLM-RS、DMRS和HARQ信息中的至少两项，且每项可以包括一个或者多个监测对象，同理，上述BFD的监测对象也可以包括一个或者多个监测对象。具体可以是一个指示周期内的监测对象可以包括一个或者多个监测对象，如一个指示周期的RLM-RS可以包括一个或者多个CSI-RS。
另外，采用DMRS或者HARQ信息进行RLM过程或者BFD过程时，可以采用CSI-RS或者SSB进行RLM过程或者BFD过程的方式，当然，对此不作限定，也可以采用其他的方式来进行RLM过程或者BFD过程。
需要说明的是，本发明实施例中，对监测对象不作限定，例如：监测对象还可以是各种物理信道，例如PDCCH、PDSCH、PSFCH等物理信道或者这些信道对应的DMRS。另外，上述本发明实施例中，并不限定监测对象为RLM和BFD的监测对象，例如：步骤201中的监测对象可以包括DMRS和HARQ信息中的至少一项，且这至少一项可以用于除RLM和BFD之外的链路的其他监测。
优选的，上述上报链路质量信息是指向所述终端的媒体接入控制(Media Access Control，MAC)层或者层3上报链路质量信息；和/或
所述不上报链路质量信息是指不向所述终端的MAC层或者层3上报链路质量信息。
作为一种可选的实施方式，上述监测对象是网络配置、预先定义、预配置或者旁链路sidelink终端指示的。
且上述第一周期内包括的监测对象的个数可以是网络配置预先定义、预配置或者旁链路sidelink终端指示的，例如：对于一个链路监测过程，例如，无线链路监测或者波束失败检测，网络可以配置一个或者多个监测对象，如配置一个或者多个CSI-RS和/或一个或者多个SSB。
作为一种可选的实施方式，若所述第一周期内不存在监测对象，则所述行为包括不上报链路质量信息或者不评估链路质量。
其中，上述第一周期内不存在监测对象可以是，上述第一周期内不存在任何监测对象，或者上述第一周期内不存在部分监测对象，例如：第一周期用于监测多个监测对象，则可以是存在部分的监测对象，但不存在另一部分监测对象，如针对RLM，第一周期内可以存在CSI-RS，但不存在SSB，或者第一周期内存在一个CSI-RS，而不存在另一个CSI-RS。
而上述不上报链路质量信息可以是不基于不存在的监测对象的链路质量信息上报，或者不基于第一周期的所有监测对象的链路质量信息上报。
而上述不评估链路质量可以是不基于不存在的监测对象评估链路质量。例如：如果对于RLM-RS/BFD-RS，在评估周期内的指示周期内，如果没有可获得的RS，则不上报链路质量信息，或者不使用该指示周期内的无法获得的RS进行链路质量的评估。
该实施方式中，由于所述第一周期内不存在监测对象，则所述行为包括不上报链路质量信息或者不评估链路质量，这样可以避免使用不可获得的监测对象来上报链路质量信息或者评估链路质量，以提高链路监测质量。
例如：如图3所示，终端的评估周期的长度为W倍的指示周期，在当前的指示周期内，终端基于当前指示周期内的RS及前W-1个指示周期内的RS，综合进行链路质量的评估。
如果当前指示周期内，没有检测到对应的RS，例如，所有的网络配置的RLM-RS/BFD-RS都无法获得，则当前指示周期，终端不进行链路质量的评估和/或上报。
如果网络配置了W个RLM-RS，如果在当前指示周期内，所有的RS都无法获得，则终端不上报链路质量评估和/或上报。
作为一种可选的实施方式，在所述第一周期进行N个监测对象的监测，若所述第一周期内不存在M个监测对象，则所述行为包括不上报链路质量信息，其中，所述N为大于或者等于1的整数，所述M为小于或者等于所述N的整数。
其中，上述在所述第一周期进行N个监测对象的监测可以是，该第一周期用于N个监测对象的监测，例如：这N个监测对象可以包括一个或者多个CSI-RS和一个或者多个SSB。上述M为小于或者等于所述N的整数可以是 理解为，若上述第一周期所有或者部分监测对象不存在，则不上报链路质量信息或者不评估链路质量。例如：在指示周期内所有或者部分的监测对象都不可获得(unavailable)，即未检测到发送了该目标对象，则终端不上报链路质量信息。其中，上述M可以为高层参数配置的大于或者等于1，且小于或者等于N的整数。
该实施方式中，可以实现若第一周期内不存在M个监测对象，则不上报链路质量信息，以提高链路质量信息的精确度。
作为一种可选的实施方式，若所述第一周期不存在第一监测对象，但存在第二监测对象，则所述行为包括：不基于所述第一监测对象评估链路质量和基于所述第二监测对象评估链路质量。
其中，对于RLM链路监测或者BFD链路监测，上述第一监测对象和第二监测对象可以是的不同监测对象，例如：不同的SSB，或者CSI-RS，或者DMRS。
该实施方式中，可以实现根据存在监测对象评估链路质量，当然，也可以根据存在的监测对象评估的链路质量上报链路质量信息，以及可以实现不基于上述第一监测对象评估链路质量，从而提高链路测量精确度。例如：在指示周期内有部分目标对象都无法获得，则终端根据可获得的目标对象进行链路质量的评估。
例如：若网络给终端配置了T个RS，用作RLM，若在当前的指示周期，其中有H(H<T)个RS无法获得，即终端没有检测到，那么终端在当前的指示周期，只基于T-H个RS进行RLM的评估，若T-H个RS中所有的RS的评估结果都高于门限值Qout对应的PDCCH-误块率(Block error rate，BLER)门限，则向高层指示失步(Out-of-sync，OOS)；对于RLM，若在可获得的RS中，有一个RS评估结果低于门限值Qin对应的PDCCH-BLER门限，则向高层指示同步(In-sync，IS)。
若网络给终端配置了T个RS，用作BFD，若在当前的指示周期，其中有H(H<T)个RS无法获得，即终端没有检测到，那么终端在当前的指示周期，只基于T-H个RS进行BFD的评估，若T-H个RS中所有的RS的评估结果都高于门限值Qout对应的PDCCH-BLER门限，则向高层波束失败指 示(beam failure indication，BFI)。
另外，如图4所示，如果配置了2个RS用作链路监测，在当前指示周期RS1无法获得，但是RS2可以获得，则根据RS2进行无线链路质量的评估。
作为一种可选的实施方式，上述监测对象包括第三监测对象，所述第一周期为所述第三监测对象对应的指示周期，且评估周期包括K个指示周期，K为大于或者等于1的整数，所述方法还包括：
若所述评估周期内有指示周期不存在所述第三监测对象，则将所述评估周期延长一个或者多个指示周期，其中，延长的部分位于所述评估周期的起始指示周期之前。
其中，上述延长的部分位于所述评估周期的起始指示周期之前可以是，将上述评估周期之前的一个或者多个指示周期延长到该估计周期内。也就是说，该实施方式中的延长是沿着时间倒退的方向延长。
其中，上述第三监测对象可以是链路监测使用的多个监测对象中的一个监测对象，例如：RLM-RS配置了多个RS，则第三监测对象可以是这多个RS中的一个RS。或者，上述第三监测对象可以是SSB、CSI-RS、DMRS或者HARQ信息。
上述评估周期内有指示周期不存在所述第三监测对象可以是，评估周期内有一个或者多个指示周期不存在所述第三监测对象。
该实施方式中，可以实现对于一个监测对象，在链路质量评估的评估期内的部分指示周期不存在该监测对象时，则将评估周期向前延伸，以使得评估周期内存在的该监测对象的数量得到提升，以提高链路评估的精确度。
可选的，所述若所述评估周期内有指示周期不存在所述第三监测对象，则将所述评估周期延长一个或者多个指示周期，包括：
若所述评估周期内有J个指示周期不存在所述第三监测对象，则将所述评估周期延长J个指示周期，或者，将所述评估周期延长，直到延长的指示周期内包括J个用于监测所述第三监测对象的指示周期，其中，所述J为小于或者等于所述K的整数。
其中，上述将所述评估周期延长J个指示周期可以提升评估周期内存在的该监测对象的数量，以提高链路评估的精确度。而上述将所述评估周期向 前延长，直到延长的指示周期内包括J个用于监测所述第三监测对象的指示周期可以保证，评估周期所存在的第三监测对象的数量与估计周期内配置的第三监测对象的数量相同，以进一步提高链路评估的精确度。
可选的，所述若所述评估周期内有指示周期不存在所述第三监测对象，则将所述评估周期延长一个或者多个指示周期，包括：
若所述第一周期存在所述第三监测对象，且所述评估周期中至少一个指示周期中不存在所述第三监测对象，则将所述评估周期延长一个或者多个指示周期。
其中，上述若所述第一周期存在所述第三监测对象，且所述评估周期中至少一个指示周期中不存在所述第三监测对象可以是，上述评估周期内且在上述第一周期之前，一些指示周期内不存在第三监测对象，但在上述第一周期内存在第三监测对象。这样可以实现只有在检测到存在第三监测对象时才延长评估周期，以使得延长的评估周期内能包含更多的第三监测对象，提高评估精度。且上述延长一个或者多个指示周期可以是参考上述将所述评估周期延长J个指示周期，或者，将所述评估周期延长，直到延长的指示周期内包括J个用于监测所述第三监测对象的指示周期的方式。
例如：一个评估周期内可能包含多个指示周期，对于某个RS，如果其中的部分指示周期内没有可用的RS，则可以将评估周期向前延长。对于某个配置的RS，在该评估周期内有X个指示周期内没有可获得的该RS，则向前延伸评估周期，使得向前延伸的时间段能包含X个存在可获得该RS的指示周期。如图5所示，对于不同的RS，由于在评估周期内，不存在RS的指示周期数目可能不同，那么需要向前延伸的评估周期的长度可能会不同。或者可以认为，评估周期长度是动态的长度，为评估周期内能容纳的包含RS的指示周期的数目对应的长度。
优选的，上述延伸评估期的行为，可以是只有在当前的指示期包含该RS的情况下，对该RS的评估期向前延伸。若不包含RS，则在当前指示周期内，不使用该RS进行链路质量评估。如图5所示，只对RS2进行评估，且评估周期进行延长。
进一步的，可以对延伸的评估的长度，或者经过延伸后的总的评估周期 的长度做进一步限定，例如，延伸的评估的时间长度，或者延伸后的评估周期之间长度，不能超过Y个指示周期，该最大长度可以由网络配置，或者为预设值。
作为一种可选的实施方式中，若上述监测对象为RLM的监测对象和BFD的监测对象中的一项，则上述方法还包括如下至少一项：
若所述终端运行有无线链路失败RLF定时器，且所述第一周期内不存在监测对象，则将所述RLF定时器的时长延长；
若所述终端运行有指示波束失败检测定时器，且所述第一周期内不存在监测对象，则将所述波束失败检测定时器的时长延长。
其中，上述将所述RLF定时器的时长延长可以是，指示高层延长RLF定时器，由高层延长RLF定时器；上述将所述波束失败检测定时器的时长延长可以是，指示高层延长波束失败检测定时器，由高层延长波束失败检测定时器。当然，本实施例中，并不限定指示高层延长定时器，也可以是其他层延长定时器。另外，上述延长可以是延长一个或者多个指示周期。
例如：对于RLM，在T310计时器运行期间，如果在一个指示周期内不存在RLM-RS，则终端自动延长T310，如指示上层T310计数器延长，优选的，延长一个指示周期。
对于BFD，如果在一个指示周期内没有可用的BFD-RS，则终端自动延长波束失败检测定时器，如指示上层波束失败检测定时器延长，优选的，延长一个指示周期。
该实施方式中，由于可以将RLF定时器和波束失败检测定时器的时长延长，从而使得RLF和RLM的精确度更高。
作为一种可选的实施方式，若所述终端在所述第一周期检测到所述监测对象，则确定所述第一周期内存在所述监测对象；和/或
若所述终端在所述第一周期未检测到所述监测对象，则确定所述第一周期内不存在所述监测对象。
上述在所述第一周期检测到所述监测对象可以是，检测到在第一周期内有发送上述监测对象，例如：终端可以通过接收机检测网络设备或者其他终端是否在第一周期内发送有上述监测对象。例如：如果监测对象为RS，终端 可以通过序列相关检测判断终端检测RS是否发送，如果检测到了RS的发送，则认为RS存在；否则，认为RS不存在。
该实施方式中，可以实现通过终端在第一周期是否检测到监测对象，来确定第一周期内是否存在监测对象，从而准确地判断第一周期是否存在上述监测对象。
作为一种可选的实施方式，上述第一周期为评估周期内的指示周期，若所述评估周期中的第一部分指示周期内不存在监测对象，但所述评估周期中的第二部分指示周期内存在监测对象，则所述行为包括评估链路质量和/或上报链路质量信息；
其中，所述评估链路质量为基于所述第二部分指示周期内的监测对象评估链路质量，所述上报链路质量信息为基于估计的链路质量上报链路质量信息，所述估计的链路质量为基于所述第二部分指示周期内的监测对象评估的链路质量。
该实施方式中，可以实现基于存在监测对象的指示周期评估链路质量，以及上报链路质量信息，以提高链路监测质量的精确度。
例如：如图6所示，终端的评估周期的长度为W倍的指示周期，在当前的指示周期内，终端基于当前指示周期内的RS及前W-1个指示周期内的RS，进行链路质量的评估。
如果当前评估周期内，有部分指示周期内的RS没有获得，则终端根据评估周期内的可以获得的RS，进行RLM/BFD的测量和评估，并根据现有规则上报链路质量。
本发明实施例中，依据第一周期内是否存在监测对象，确定链路监测的行为，其中，所述行为包括以下至少一项；上报链路质量信息、不上报链路质量信息、评估链路质量或者不评估链路质量。这样可以根据周期内是否存在监测对象的实际情况来确定链路监测的行为，从而可以提高终端监测链路的能力。
