  • the R criteria for the cell ranking level are as follows:
  • R s Q meas,s +Q Hyst –Q offsettemp

  • the mobility state in LTE is determined by determining that if the number of cell reselections is greater than N CR_M and less than N CR — H within time T CRmax , it is determined that the terminal device satisfies a medium-mobility state criterion; within the time T CRmax, the cell reselection count is greater than N CR_H, determining whether the terminal device satisfies high-speed movement (high-mobility) state guidelines.
  • the terminal device enters a high-speed moving state; if the medium-speed moving state criterion is met, the terminal device enters a medium-speed moving state; if the high-speed moving state criterion is not satisfied within the time T CRmaxHyst If the medium speed moving state criterion is not met, the terminal device enters a normal-mobility state.
  • the parameter does not use the scaling criterion; if the terminal device is in the high-speed moving state, Q Hyst plus the scaling factor sf-High is taken as its value, and the timer for cell reselection will be used.

Abstract

Description

参数确定和配置方法、装置及通信系统 技术领域
本发明实施例涉及通信技术领域，特别涉及一种参数确定和配置方法、装置及通信系统。
背景技术
在长期演进(LTE，Long Term Evolution)中，终端设备一般重选到最高等级的候选小区。其中，用于小区重选的时间长度T reselection以及用于小区排列等级的小区滞后参数Q Hyst都可以基于终端设备的速度进行缩放。
在LTE中，终端设备的速度可以由移动性状态(高、中、正常)来定义。对于处于空闲(Idle)模式的终端设备，速度估计是基于网络设备配置的时间(T CRmax、T CRmaxHyst)内的小区重选的个数(N CR_M、N CR_H)来进行的。这些参数被网络设备在系统信息(SI，System Informatica)中广播。
根据由速度估计出的移动性状态，终端设备将缩放它的小区重选参数。LTE中使用的比例缩放值为0.25、0.5、0.75、和1。Q Hyst的取值将对小区重选过程中的小区排列等级有作用。小区排列等级的R准则如下：
R s＝Q meas,s+Q Hyst–Q offsettemp
R n＝Q meas,n–Q offset–Q offsettemp
例如，LTE中的移动性状态通过如下方式确定：如果在时间T CRmax内，小区重选次数大于N CR_M并且小于N CR_H，则确定该终端设备满足中速移动(medium-mobility)状态准则；如果在时间T CRmax内，小区重选次数大于N CR_H，则确定该终端设备满足高速移动(high-mobility)状态准则。
如果满足高速移动状态准则，则该终端设备进入高速移动状态；如果满足中速移动状态准则，则该终端设备进入中速移动状态；如果在时间T CRmaxHyst内，既没有满足高速移动状态准则，也没有满足中速移动状态准则，则该终端设备进入正常移动状态(normal-mobility)。
此外，如果终端设备处于正常移动状态，则参数不使用缩放准则；如果终端设备处于高速移动状态，则将Q Hyst加上缩放因子sf-High作为它的值，将用于小区重选的 定时器的T reselectionRAT值乘以缩放因子sf-High作为它的值；如果终端设备处于中速移动状态，则将Q Hyst加上缩放因子sf-medium作为它的值，将T reselectionRAT值乘以缩放因子sf-medium作为它的值。
此外，如果多个不同优先级的小区满足重选准则，那么选择优先级最高的小区。在优先级相同的多个小区满足重选准则的情况下，根据上述R准则进行排序，选择最优的小区。
应该注意，上面对技术背景的介绍只是为了方便对本发明的技术方案进行清楚、完整的说明，并方便本领域技术人员的理解而阐述的。不能仅仅因为这些方案在本发明的背景技术部分进行了阐述而认为上述技术方案为本领域技术人员所公知。
发明内容
但是，发明人发现：终端设备在移动更快的时候，将执行更多小区重选评估，可能在服务小区中停留更短时间。当大小区的覆盖内出现小小区时，基于速度估计的参数缩放可能导致更多小区重选，并且终端设备在每次小区重选时读取系统信息将造成更多负担。
此外，LTE中基于小区重选个数的速度估计不直接反映速度大小，而是依赖于终端设备的移动方向、网络小区大小和网络小区形状。在LTE网络中基于小区重选个数进行速度估计来确定移动性状态，进而缩放小区重选参数的增益并不显著。

实施例1
本发明实施例提供一种参数确定方法。
图2是本发明实施例的参数确定方法的示意图，示出了终端设备侧的情况。如图2所示，参数确定方法200包括：
步骤201，终端设备根据其所在的服务小区或服务波束的信号质量的变化量，确定所述终端设备的状态；以及
步骤202，终端设备基于确定的所述状态来维持或调整所述终端设备的参数。
在本实施例中，所述信号质量包括如下参数的至少之一：信干噪比(SINR，Signal to Interference plus Noise Ratio)、参考信号接收质量(RSRQ，Reference Signal Received Quality)和参考信号接收功率(RSRP，Reference Signal Received Power)。但本发明不限于此，例如还可以是信号质量的其他指标。
在本实施例中，终端设备可以在如下的状态下进行状态检测：例如，RRC_IDLE 态，或者RRC_INACTIVE态，或者RRC_Connected态；但本发明不限于此。另外，本发明实施例的信号质量的变化量可以是信号质量的上升量，也可以是信号质量的下降量；例如可以是SINR/RESQ/RSRP的两个测量值的差值。
此外，该信号质量的改变量可以是由于终端设备从小区中心移动到小区边缘引起的，也可以是由于终端设备穿过小小区而引起的，但本发明不限于此，本发明不对具体场景进行限制。
图3是本发明实施例的信号质量的变化量对于状态检测的影响的一个示意图。如图3所示，Cell 1表示终端设备的服务小区或波束(beam)，Cell 2表示终端设备的邻小区或波束。如图3所示，如果终端设备从服务小区中心到服务小区边缘以高速移动，那么在T1这段时间中服务小区或服务波束的SINR/RSRQ/RSRP改变量将很大。
图4是本发明实施例的信号质量的变化量对于状态检测的影响的另一个示意图。如图4所示，Cell 1表示终端设备的服务小区或波束，Cell 2表示终端设备的邻小区或波束。如图4所示，如果终端设备的服务小区是小小区，并且从服务小区中心到服务小区边缘移动，即使该终端设备的移动速度正常，在T1这段时间中服务小区或服务波束的SINR/RSRQ/RSRP改变量也可能很大。
因此，基于服务小区或服务波束的信号质量的变化量，本发明实施例能够准确地进行状态检测。
此外，如果终端设备在服务小区中心以高速移动，在T1这段时间中服务小区或服务波束的SINR/RSRQ/RSRP改变量可能不大。根据本发明实施例的状态检测准则，这种情况下，终端设备可能处于正常移动状态中。但由于终端设备此时在服务小区中心，不会进行小区重选或切换或波束失败恢复操作，因此该状态检测对于移动性性能几乎没有影响。
以下以三个状态为例，对本发明实施例进行进一步说明。
在一个实施方式中，在一个时间段内的一个变化量高于预设的第一门限值的情况下、或者在一个或多个时间段内的多个变化量均高于所述第一门限值的情况下，将所述终端设备确定为满足第一状态；和/或
在所述一个时间段内的一个变化量高于预设的第二门限值且低于或等于所述第一门限值的情况下、或者在所述一个或多个时间段内的多个变化量均高于所述第二门限值且均低于或等于所述第一门限值的情况下，将所述终端设备确定为满足第二状 态；和/或
在所述一个时间段内的一个变化量低于或等于所述第二门限值的情况下、或者在所述一个或多个时间段内的多个变化量均低于或等于所述第二门限值的情况下，将所述终端设备确定为满足第三状态。
例如，如果在时间段T1内，服务小区或服务波束的SINR/RSRQ/RSRP改变量高于门限1，则可以确定为状态1；如果在时间段T1内，服务小区或服务波束的SINR/RSRQ/RSRP改变量高于门限2并且低于门限1，则可以确定为状态2；如果在时间段T1内，服务小区或服务波束的SINR/RSRQ/RSRP改变量低于门限2，则可以确定为状态3(例如称为normal状态)。
在本实施方式中，T1可以设置的比较短，因此可以捕获相对动态(瞬时的)的一个SINR/RSRQ/RSRP改变量。此外，为了保持稳定的状态、以避免频繁的状态转移，终端设备还可以收集服务小区或服务波束的SINR/RSRQ/RSRP的多个改变量。
例如，收集的服务小区或服务波束的SINR/RSRQ/RSRP改变量的个数N可以被网络设备配置，或者可以在规范中被预定义。例如，当N个SINR/RSRQ/RSRP改变量都高于门限1时，才达到状态1的标准。
再例如，还可以配置大于T1的相对较长的时间段T2，该时间段T2可以被网络设备配置、或者可以在规范中被预定义。例如，当在T2时间内服务小区或服务波束的SINR/RSRQ/RSRP的多个改变量都高于门限1时，才达到状态1的标准。
以上使用服务小区或服务波束的信号质量的变化量进行状态检测，此外还可以在此基础上增加更多的检测量。例如，根据所述终端设备所在的服务小区或服务波束的信号质量的变化量以及所述服务小区或服务波束的信号质量的测量值，确定所述终端设备的状态。由此，可以进一步提高状态检测的准确性。
在一个实施方式中，在一个时间段内的一个变化量高于预设的第三门限值或者在一个或多个时间段内的多个变化量均高于所述第三门限值、且所述一个或多个时间段内所述服务小区或服务波束的信号质量的多个测量值均低于或等于第四门限值的情况下，将所述终端设备确定为满足第一状态；和/或
在所述一个或多个时间段内所述服务小区或服务波束的信号质量的多个测量值中的至少一个低于或等于所述第四门限值的情况下，或者，在所述一个或多个时间段内的至少一个变化量高于所述第三门限值的情况下，将所述终端设备确定为满足第二 状态；和/或
在所述一个时间段内的一个变化量低于或等于所述第三门限值或者在所述一个或多个时间段内的多个变化量均低于或等于所述第三门限值、且所述一个或多个时间段内所述服务小区或服务波束的信号质量的多个测量值中的至少一个高于所述第四门限值的情况下，将所述终端设备确定为满足第三状态。
例如，如果在一个时间段T3内，服务小区或服务波束的SINR/RSRQ/RSRP多个测量结果都低于门限3，且该时间段T3内SINR/RSRQ/RSRP的一个改变量高于门限4，则可以确定为状态1；
如果在一个时间段T3内，服务小区或服务波束的SINR/RSRQ/RSRP的至少一个测量结果低于门限3，且该时间段T3内SINR/RSRQ/RSRP的一个改变量低于门限4，可以确定为状态2；或者，如果在一个时间段T3内，SINR/RSRQ/RSRP的至少一个测量结果高于门限3，且该时间段T3内的SINR/RSRQ/RSRP的一个改变量高于门限4，则可以确定为状态2；
如果在一个时间段T3内，服务小区或服务波束的SINR/RSRQ/RSRP的至少一个测量结果高于门限3，且该时间段T3内的SINR/RSRQ/RSRP的一个改变量低于门限4，则可以确定为状态3(normal状态)。
在本实施方式中，T3可以设置的比较短，因此可以捕获相对动态(瞬时的)的一个SINR/RSRQ/RSRP改变量。此外，为了保持稳定的状态、以避免频繁的状态转移，终端设备还可以收集服务小区或服务波束的SINR/RSRQ/RSRP的多个改变量。
例如可以配置个数N，对于N个时间段T3中的每个T3分别计算改变量，从而获得N个改变量。如果在N个时间段T3内，服务小区或服务波束的SINR/RSRQ/RSRP多个测量结果都低于门限3，且SINR/RSRQ/RSRP的N个改变量均高于门限4，则可以确定为状态1；
如果在N个时间段T3内，服务小区或服务波束的SINR/RSRQ/RSRP的至少一个测量结果低于门限3；或者，如果在N个时间段T3内，服务小区或服务波束的SINR/RSRQ/RSRP的N个改变量中的至少一个高于门限4，则可以确定为状态2；
如果在N个时间段T3内，服务小区或服务波束的SINR/RSRQ/RSRP的测量结果均高于门限3，且SINR/RSRQ/RSRP的N个改变量均低于门限4，则可以确定为状态3(normal状态)。
再例如，可以将T3设置的较长。在该时间段T3中多次计算改变量(次数例如可以预先配置或定义)，从而获得N个改变量。如果在该时间段T3内，服务小区或服务波束的SINR/RSRQ/RSRP多个测量结果都低于门限3，且SINR/RSRQ/RSRP的N个改变量均高于门限4，则可以确定为状态1；
如果在该时间段T3内，服务小区或服务波束的SINR/RSRQ/RSRP的至少一个测量结果低于门限3；或者，如果在该时间段T3内，服务小区或服务波束的SINR/RSRQ/RSRP的N个改变量中的至少一个高于门限4，则可以确定为状态2；
如果在该时间段T3内，服务小区或服务波束的SINR/RSRQ/RSRP的测量结果均高于门限3，且SINR/RSRQ/RSRP的N个改变量均低于门限4，则可以确定为状态3(normal状态)。
值得注意的是，上述实施方式中对于第一状态、第二状态和第三状态的判断可以单独执行，也可以两个或以上结合起来执行。此外，对于各个状态的执行顺序不进行限制，当然也可以按照第一状态、第二状态和第三状态的顺序进行判断。
例如，在上述三个状态的判断都执行的情况下，可以进行如下处理：
在一个时间段内的一个变化量高于预设的第三门限值或者在一个或多个时间段内的多个变化量均高于所述第三门限值、且所述一个或多个时间段内所述服务小区或服务波束的信号质量的多个测量值均低于或等于第四门限值的情况下，将所述终端设备确定为满足第一状态；
在所述一个时间段内的一个变化量低于或等于所述第三门限值或者在所述一个或多个时间段内的多个变化量中的至少一个低于或等于所述第三门限值、且所述一个或多个时间段内所述服务小区或服务波束的信号质量的多个测量值中的至少一个低于或等于所述第四门限值的情况下，或者，在所述一个时间段内的一个变化量高于所述第三门限值或者在所述一个或多个时间段内的至少一个变化量均高于所述第三门限值、且所述一个或多个时间段内所述服务小区或服务波束的信号质量的多个测量值中的至少一个高于所述第四门限值的情况下，将所述终端设备确定为满足第二状态；以及
在所述一个时间段内的一个变化量低于或等于所述第三门限值或者在所述一个或多个时间段内的多个变化量均低于或等于所述第三门限值、且所述一个或多个时间段内所述服务小区或服务波束的信号质量的多个测量值中的至少一个高于所述第四 门限值的情况下，将所述终端设备确定为满足第三状态。
在另一个实施方式中，在一个时间段内的一个变化量高于预设的第五门限值或者在一个或多个时间段内的多个变化量均高于预设的第五门限值、且所述服务小区或服务波束的信号质量的当前测量值低于或等于第六门限值的情况下，将所述终端设备确定为满足第一状态；和/或
在所述服务小区或服务波束的信号质量的当前测量值低于或等于所述第六门限值的情况下，或者，在所述一个或多个时间段内的多个变化量中的至少一个高于所述第五门限值的情况下，将所述终端设备确定为满足第二状态；和/或
在所述一个时间段内的变化量低于或等于所述第五门限值或者在所述一个或多个时间段内的多个变化量均低于或等于所述第五门限值、且所述服务小区或服务波束的信号质量的当前测量值高于所述第六门限值的情况下，将所述终端设备确定为满足第三状态。
例如，如果在一个时间段T4内，服务小区或服务波束的SINR/RSRQ/RSRP的一个改变量高于门限5，且当前服务小区或服务波束的SINR/RSRQ/RSRP的一个测量结果低于门限6，则可以确定为状态1；
如果在一个时间段T4内，服务小区或服务波束的SINR/RSRQ/RSRP的一个改变量低于门限5，且当前服务小区或服务波束的SINR/RSRQ/RSRP的一个测量结果低于门限6，则可以确定为状态2；或者，如果在一个时间段T4内，SINR/RSRQ/RSRP的一个改变量高于门限5，且当前的SINR/RSRQ/RSRP的一个测量结果高于门限6，则可以确定为状态2；
如果在一个时间段T4内，服务小区或服务波束的SINR/RSRQ/RSRP的一个改变量低于门限5，且当前服务小区或服务波束的SINR/RSRQ/RSRP的一个测量结果高于门限6，则可以确定为状态3(normal状态)。
在本实施方式中，T4可以设置的比较短，因此可以捕获相对动态(瞬时的)的一个SINR/RSRQ/RSRP改变量。此外，为了保持稳定的状态、以避免频繁的状态转移，终端设备还可以收集服务小区或服务波束的SINR/RSRQ/RSRP的多个改变量。
例如，可以配置个数N，对于N个时间段T4中的每个T4分别计算改变量，从而获得N个改变量。如果在N个时间段T4内，服务小区或服务波束的SINR/RSRQ/RSRP的N个改变量均高于门限5，且当前服务小区或服务波束的SINR/RSRQ/RSRP 的一个测量结果低于门限6，则可以确定为状态1；
如果在N个时间段T4内，当前服务小区或服务波束的SINR/RSRQ/RSRP的一个测量结果低于门限6，或者，如果在N个时间段T4内，SINR/RSRQ/RSRP的N个改变量的至少一个高于门限5，则可以确定为状态2；
如果在N个时间段T4内，服务小区或服务波束的SINR/RSRQ/RSRP的N个改变量均低于门限5，且当前服务小区或服务波束的SINR/RSRQ/RSRP的一个测量结果高于门限6，则可以确定为状态3(normal状态)。
再例如，可以将T4设置的较长。在该时间段T4中多次计算改变量(次数例如可以预先配置或定义)，从而获得N个改变量。如果在该时间段T4内，服务小区或服务beam的SINR/RSRQ/RSRP的N个改变量均高于门限5，且当前服务小区或服务beam的SINR/RSRQ/RSRP的一个测量结果低于门限6，则可以确定为状态1；
如果在该时间段T4内，当前服务小区或服务波束的SINR/RSRQ/RSRP的一个测量结果低于门限6；或者，如果在该时间段T4内，SINR/RSRQ/RSRP的N个改变量的至少一个高于门限5，则可以确定为状态2；
如果在该时间段T4内，服务小区或服务波束的SINR/RSRQ/RSRP的N个改变量均低于门限5，且当前服务小区或服务波束的SINR/RSRQ/RSRP的一个测量结果高于门限6，则可以确定为状态3(normal状态)。
值得注意的是，上述实施方式中对于第一状态、第二状态和第三状态的判断可以单独执行，也可以两个或以上结合起来执行。此外，对于各个状态的执行顺序不进行限制，当然也可以按照第一状态、第二状态和第三状态的顺序进行判断。
例如，在上述三个状态的判断都执行的情况下，可以进行如下处理：
在一个时间段内的一个变化量高于预设的第五门限值或者在一个或多个时间段内的多个变化量均高于预设的第五门限值、且所述服务小区或服务波束的信号质量的当前测量值低于或等于第六门限值的情况下，将所述终端设备确定为满足第一状态；
在所述一个时间段内的一个变化量低于或等于所述第五门限值或者在所述一个或多个时间段内的多个变化量中的至少一个低于或等于所述第五门限值、且所述服务小区或服务波束的信号质量的当前测量值低于或等于所述第六门限值的情况下，或者，在所述一个时间段内的一个变化量高于所述第五门限值或者在所述一个或多个时间段内的多个变化量中的至少一个高于所述第五门限值、且所述服务小区或服务波束 的信号质量的当前测量值高于所述第六门限值的情况下，将所述终端设备确定为满足第二状态；以及
在所述一个时间段内的变化量低于或等于所述第五门限值或者在所述一个或多个时间段内的多个变化量均低于或等于所述第五门限值、且所述服务小区或服务波束的信号质量的当前测量值高于所述第六门限值的情况下，将所述终端设备确定为满足第三状态。
值得注意的是，以上对如何确定状态进行了示意性说明，但本发明不限于此。例如还可以有更多状态，即可以根据相同的原则对状态进一步细分。以下对于本发明再进行进一步说明。
图5是本发明实施例的参数确定方法的示意图，示出了终端设备侧和网络设备侧的情况。如图5所示，参数确定方法500包括：
步骤501，网络设备向终端设备发送用于确定参数的信息。
例如，所述信息可以包括如下配置信息的至少之一：指示是否执行状态检测的信息、指示针对服务小区还是服务波束进行状态检测的信息、指示所述信号质量的类型的信息；但本发明不限于此。
此外，网络设备还可以发送如下指示信息的至少之一：用于确定状态的一个或多个门限值、计算所述改变量的时间段的长度、计算所述改变量的时间段的个数和所述改变量的个数；但本发明不限于此。
上述信息可以被承载在系统信息中，或者也可以被承载在无线资源控制(RRC，Radio Resource Control)消息中。此外，可以通过一个或多个系统信息发送，也可以通过一个或多个RRC消息发送。
步骤502，终端设备确定预定条件被满足；
例如，所述预定条件至少包括如下之一：所述服务小区或者服务波束的信号质量低于预定门限值；所述终端设备执行同频测量或者异频测量或者无线接入技术间测量；所述终端设备到达周期性配置的时刻；所述服务小区或服务波束的信号质量和/或路径损耗的变化量高于预定门限值；所述终端设备检测到邻小区。但本发明不限于此，还可以包括其他的条件。
步骤503，终端设备计算一个或多个时间段内所述服务小区或服务波束的信号质量的变化量。
由此，通过设置预定条件，在预定条件被满足的情况下才进行所述变化量的计算，可以减少终端设备频繁地进行计算的情况，提升系统的整体性能。
步骤504，终端设备根据其所在的服务小区或服务波束的信号质量的变化量，确定所述终端设备的状态；以及
步骤505，终端设备基于确定的所述状态来维持或调整所述终端设备的参数。
值得注意的是，以上附图5仅对本发明实施例进行了示意性说明，但本发明不限于此。例如可以适当地调整各个步骤之间的执行顺序，此外还可以增加其他的一些步骤或者减少其中的某些步骤。本领域的技术人员可以根据上述内容进行适当地变型，而不仅限于上述附图5的记载。
在本实施例中，所述参数可以包括至少如下之一：小区重选时的移动性相关参数、切换时的移动性相关参数和波束失败恢复时的相关参数。以下将以小区重选过程、切换过程和波束失败恢复过程为例，对步骤505进行进一步说明，但本发明不限于此。
在一个实施方式中，所述小区重选时的移动性相关参数至少包括如下之一：用于小区重选的时间长度T reselection、用于小区排列等级的小区滞后参数Q Hyst、用于小区排列等级的偏差值Q offset、用于小区排列等级的临时偏差值Q offsettemp。
以小区重选为例，可以进行如下操作来维持或调整所述终端设备的参数。
例如，如果UE保持在状态3(normal状态)，则不应用参数缩放。
如果UE检测到状态1，则执行下面的行为中至少一个：增加Q1(缩放因子)到Q Hyst，或者将Q Hyst乘以Q1，其中Q1可以在系统信息中或RRC专用消息中被发送。对于邻小区，将它们各自的T reselection乘以factor1(缩放因子)，其中factor1可以在系统信息中或RRC专用消息中被发送；增加A1(缩放因子)到Q offset，或者将Q offset乘以A1，其中A1可以在系统信息中或RRC专用消息中被发送；增加B1(缩放因子)到Q offsettemp，或者Q offsettemp乘以B1，其中B1可以在系统信息中或RRC专用消息中被发送。
如果UE检测到状态2，则执行下面的行为中至少一个：增加Q2(缩放因子)到Q Hyst，或者将Q Hyst乘以Q2，其中Q2可以在系统信息中或RRC专用消息中被发送；对于邻小区，将它们各自的T reselection乘以factor2(缩放因子)，其中factor2可以在系统信息中或RRC专用消息中被发送；增加A2(缩放因子)到Q offset，或者将Q offset乘以A2，其中A2在系统信息中或RRC专用消息中被发送；增加B2(缩放因子)到 Q offsettemp，或者Q offsettemp乘以B2，其中B2可以在系统信息中或RRC专用消息中被发送。
在另一个实施方式中，所述切换时的移动性相关参数至少包括：触发测量报告的时间参数和/或切换滞后参数。
例如对于切换过程，参数缩放的规则与小区重选过程中的上述规则可以是相似的，不同之处可以在于将小区重选中的T reselection换为触发测量报告的时间参数(例如time to trigger)，以及将小区重选中的Q offset或Q offsettemp换成切换滞后值、或偏移值、或门限值、或测量结果等。
在另一个实施方式中，所述波束失败恢复时的相关参数至少包括如下之一：参考信号的质量门限值或偏移值、功率斜坡步长、监控响应的时间参数、失败实例连续个数。
例如对于波束失败恢复(beam failure recovery)过程，参数缩放的规则与小区重选过程中的上述规则可以是相似的。波束失败恢复过程中的相关参数例如可以是信道状态信息参考信号(CRS-RS)的质量门限(CandidateBeamThreshold)、波束失败恢复的功率斜坡步长(powerRampingStep-BFR)、在UE发送波束失败恢复请求后监控网络设备(例如gNB)响应的ResponseWindowSize-BFR、指示波束失败的波束失败实例连续个数(NrOfBeamFailureInstance)，等等。
由上述实施例可知，终端设备根据其所在的服务小区或服务波束的信号质量的变化量，确定所述终端设备的状态；以及基于确定的所述状态来维持或调整所述终端设备的参数。由此，能够准确地确定出终端设备的状态，进而准确地维持或调整相关参数。
实施例2

图6是本发明实施例的波束失败恢复的配置方法的示意图，示出了网络设备侧的情况。如图6所示，参数配置方法600包括：
步骤601，网络设备向终端设备发送用于确定参数的配置信息；其中所述配置信息被所述终端设备用于根据所述终端设备所在的服务小区或服务波束的信号质量的变化量来确定所述终端设备的状态。
例如，所述配置信息至少包括如下之一：指示是否执行状态检测的信息、指示针对服务小区还是服务波束进行状态检测的信息、指示所述信号质量的类型的信息；但本发明不限于此。
如图6所示，参数配置方法600还可以包括：
步骤602，网络设备向所述终端设备发送如下指示信息的至少之一：用于确定状态的一个或多个门限值、计算所述改变量的时间段的长度、计算所述改变量的时间段的个数和所述改变量的个数。
在本实施例中，上述信息可以被承载在系统信息中，或者也可以被承载在无线资源控制(RRC，Radio Resource Control)消息中。此外，可以通过一个或多个系统信息发送，也可以通过一个或多个RRC消息发送。
值得注意的是，以上附图6仅对本发明实施例进行了示意性说明，但本发明不限于此。例如可以适当地调整各个步骤之间的执行顺序，此外还可以增加其他的一些步骤或者减少其中的某些步骤。本领域的技术人员可以根据上述内容进行适当地变型，而不仅限于上述附图6的记载。
