为了方便理解,以下对本申请实施例涉及的一些术语进行解释说明:
1、无线链路失败RLF
根据对参考信号的测量和网络配置的参考信号质量阈值,RRC_CONNECTED用户设备(User Equipment,UE,即终端)执行无线链路监控(Radio Link Monitoring,RLM)。当UE满足了如下条件时,则可以宣称RLF:
在物理层指示无线链路发生问题(指示N310次“丢失同步(out-of-sync)”)后启动的T310计时器超时;
当T310正在运行时,一个测量报告被触发,该测量报告对应的测量标识被配置的计时器T312超时;
媒体接入控制(Medium Access Control,MAC)层随机接入流程失败;
无线链路控制(Radio Link Control,RLC)层的最大重传次数达到上限导致的RLC失败。
当RLF发生,UE维持在RRC_CONNECTED态并选择合适的小区触发RRC重建立流程;如果在T311超时前UE没有找到合适的小区,则UE进入RRC_IDLE。
2、定时器/计数器
第五代移动通信技术(5th Generation Mobile Communication Technology,5G)NR系统中终端侧维护多个网络侧配置的定时器和计数器,以控制RRC连接建立、重建、恢复过程,以及无线链路监测RLM,波束失败检测(Beam Failure Recovery,BFD),切换过程的随机接入等移动性相关过程。
定时器具体包含以下:
T300:UE等待无线资源控制(Radio Resource Control,RRC)连接响应的定时器;
T301:UE等待RRC重建立过程的定时器;
T304:UE随机接入到特殊小区(Special Cell,SpCell)的定时器;
T310:UE监测无线链路失败(Radio Link Failure,RLF)的定时器;
T311:UE监测到RLF后转空闲态的定时器;
T312:用于快速切换失败恢复的定时器;
T316:用于快速(fast)主小区组(Master Cell Group,MCG)连接恢复(link recovery)的定时器;
T319:UE等待RRC连接恢复响应的定时器;
beamFailureDetectionTimer:用于波束失败检测流程的定时器;
beamFailureRecoveryTimer:用于波束失败恢复的定时器。
本申请实施例主要关注T304、T310、T311、T312,对UE如何定义定时器的启动、停止以及超时后的行为进行说明如下:
定时器T304:
定时器启动的条件:UE接收到携带reconfigurationWithSync的RRC重配置消息,或执行条件重配置时;
定时器停止的条件:成功完成在对应SpCell上的随机接入;对于辅小区组(Secondary Cell Group,SCG),一旦SCG释放则停止T304;
定时器超时后的行为:对于主小区组(Master Cell Group,MCG),对于来自NR的切换(handover from NR)或NR内切换(intra-NR handover),发起RRC重建流程;对于handover to NR,执行源(source)RAT协议中定义的动作。如果配置了双激活协议栈(Dual Active Protocol Stack,DAPS)承载,并且源主服务小区(Primary cell,PCell)没有RLF,发起失败信息(failure information)流程;对于SCG,发起SCG failure information流程以通知网络使用同步重新配置(Reconfiguration with sync)失败。
定时器T310:
定时器启动的条件:检测到SpCell的物理层问题,例如从底层接收到N310个连续的out-of-sync指示;
定时器停止的条件:从底层接收到N311个连续的SpCell的in-sync指示;或接收到携带reconfigurationWithSync的RRC重配置消息;
定时器超时后的行为:对于MCG,如果接入层(Access Stratum,AS)安全未激活,进入RRC_IDLE;否则,发起MCG failure information流程或RRC连接重建流程;对于SCG,发起SCG failure information流程。
定时器T312:
定时器启动的条件:如果T312在MCG中配置:在T310运行期间,终端触发了一个测量ID对应的测量上报,且测量ID配置了T312,且use T312配置为true;如果T312在SCG中配置且useT312配置为true:在T310运行期间,终端触发了一个测量ID对应的测量上报,且测量ID配置了T312;
定时器停止的条件:从底层接收到SpCell的连续N311个in-sync指示,或接收到包含reconfigurationWithSync的RRC重配置消息,或执行条件重配;
定时器超时后的行为:如果是MCG的T312,发起MCG failure information流程或RRC连接重建流程;如果是SCG的T312,发起SCG failure information流程。
计数器具体包含以下:
N310:控制T310启动时刻的计数器;
N311:控制T310停止时刻的计数器;
beamFailureInstanceMaxCount:控制波束失败恢复(Beam Failure Recovery,BFR)触发时刻的计数器。
N310、N311的重置(Reset)、增加(Increment)时刻,及达到最大值后的动作如表1所示:
表1
其中,对于"out-of-sync"及"in-sync"指示解释如下:
终端确定Qout和Qin门限值,将对无线电链路监测-参考信号(Radio Link Monitoring-reference signal,RLM-RS)进行测量所得到的结果与此门限值进行比较,测量结果劣于Qout时上报"out-of-sync"事件;测量结果优于Qin时,则上报"in-sync"事件。
Qin是终端的下行信道质量足够好能进行可靠传输的门限值,实际转化为对PDCCH检测的块错误率(Block Error Rate,BLER)达到BLERin时的信道质量,Qout则是终端的下行信道质量已经不能进行可靠传输时的门限值,实际转化为对物理下行控制信道(Physical downlink control channel,PDCCH)检测的BLER达到BLERout时的信道质量。RLM-RS可以是同步信号块(Synchronization Signal Block,SSB),或者CSI参考信号(CSI Reference Signal,CSI-RS),也可以是SSB及CSI-RS的混合。BLERin和BLERout的配置可以如表2所示:
表2
3、人工智能(Artificial Intelligence,AI)
人工智能(AI)目前在各个领域获得了广泛的应用,将人工智能融入无线通信网络,显著提升吞吐量、时延以及用户容量等技术指标是未来的无线通信网络的重要任务。AI模块有多种实现方式,例如神经网络、决策树、支持向量机、贝叶斯分类器等。本申请实施例以神经网络为例进行说明,但是并不限定AI模块的具体类型。
一个神经网络的示意图2所示:
其中,神经网络由神经元组成,神经元的示意图如图3所示。其中a1,a2,…aK为输入,w为权值(乘性系数),b为偏置(加性系数),σ(.)为激活函数。常见的激活函数包括Sigmoid、tanh、线性整流函数或修正线性单元(Rectified Linear Unit,ReLU)等等。
神经网络的参数通过梯度优化算法进行优化。梯度优化算法是一类最小化或者最大化目标函数(或描述为损失函数)的算法,而目标函数往往是模型参数和数据的数学组合。例如给定数据X和其对应的标签Y,我们构建一个神经网络模型f(.),有了模型后,根据输入x就可以得到预测输出f(x),并且可以计算出预测值和真实值之间的差距(f(x)-Y),这个就是损失函数。找到合适的W,b使上述的损失函数的值达到最小,损失值越小,则说明模型越接近于真实情况。
目前常见的优化算法,基本都是基于误差反向传播(error Back Propagation,BP)算法。BP算法的基本思想是,学习过程由信号的正向传播与误差的反向传播两个过程组成。正向传播时,输入样本从输入层传入,经各隐层逐层处理后,传向输出层。若输出层的实际输出与期望的输出不符,则转入误差的反向传播阶段。误差反传是将输出误差以某种形式通过隐层向输入层逐层反传,并将误差分摊给各层的所有单元,从而获得各层单元的误差信号,此误差信号即作为修正各单元权值的依据。这种信号正向传播与误差反向传播的各层权值调整过程,是周而复始地进行的。权值不断调整的过程,也就是网络的学习训练过程。此过程一直进行到网络输出的误差减少到可接受的程度,或进行到预先设定的学习次数为止。
常见的优化算法有梯度下降(Gradient Descent)、随机梯度下降(Stochastic Gradient Descent,SGD)、小批量梯度下降(mini-batch gradient descent)、动量法(Momentum)、带动量的随机梯度下降(Nesterov)、自适应梯度下降(ADAptive GRADient descent,Adagrad)、Adadelta、均方根误差降速(root mean square prop,RMSprop)、自适应动量估计(Adaptive Moment Estimation,Adam)等。
这些优化算法在误差反向传播时,都是根据损失函数得到的误差/损失,对当前神经元求导数/偏导,加上学习速率、之前的梯度/导数/偏导等影响,得到梯度,将梯度传给上一层。
3.1、AI单元/AI模型:
本申请中所述的AI单元/AI模型也可称为AI单元、AI模型、机器学习(machine learning,ML)模型、ML单元、AI结构、AI功能、AI特性、机器学习模型、神经网络、神经网络函数、神经网络功能等,或者所述AI单元/AI模型也可以是指能够实现与AI相关的特定的算法、公式、处理流程、能力等的处理单元,或者所述AI单元/AI模型可以是针对特定数据集的处理方法、算法、功能、模块或单元,或者所述AI单元/AI模型可以是运行在图形处理器(Graphics processing unit,GPU)、神经网络处理器(Neural network Processing,NPU)、张量处理器(Tensor processing unit,TPU)、专用集成芯片(Application Specific Integrated Circuit,ASIC)等AI/ML相关硬件上的处理方法、算法、功能、模块或单元,本申请实施例对此不做具体限定。可选地,所述特定数据集包括AI单元/AI模型的输入或输出。

4、无线资源管理(Radio resource management,RRM)测量上报
测量配置主要由测量对象,上报配置及测量ID组成;
测量对象:(Measurement Object):即待测量的频点;
上报配置(ReportConfig):关联上报准则(周期性/事件触发);参考信号类型(SSB/CSI-RS),测量上报量(如参考信号接收功率(Reference Signal Received Power,RSRP)/参考信号接收质量(Reference Signal Received Quality,RSRQ)/信号与干扰加噪声比(Signal-to-noise and interference ratio,SINR)的任意组合);是否上报波束测量结果,可上报波束的最大个数等;

与RLF预测关联的定时器的相关信息;
预测的随机接入失败的概率;
预测的无线链路控制RLC层的重传达到最大重传次数的概率;
预测RLF发生时间的预测测量结果。
其中,RLF预测结果用于指示是否会发生RLF,例如RLF预测结果可以包括预测值,该预测值为真或假,预测值为真表征预测会发生RLF,预测值为假表征预测不会发生RLF;或,RLF预测结果可以包括预测RLF发生的概率,在预测RLF发生的概率大于或等于门限时,表征预测会发生RLF;在预测RLF发生的概率小于门限时,表征预测不会发生RLF;或,RLF预测结果可以包括预测的RLF发生的时间点,在预测的RLF发生的时间点在目标时间范围内时,表征预测会发生RLF;在预测RLF发生的时间点不在目标时间范围内时,表征预测不会发生RLF。本申请实施例对RLF预测结果的具体表现形式不进行限定。
其中,预测的随机接入失败的概率,例如,终端预测在载波聚合(Carrier Aggregation,CA)或多无线双连接(Multi-Radio Dual Connectivity,MR-DC)小区组(cell group)的服务小区上随机接入失败的概率。
其中,预测的RLC层的重传达到最大重传次数的概率,可以是,预测RLF自动重传请求(Automatic Repeat request,ARQ)会达到最大次数导致的RLC失败的概率。

一种实施方式中,所述终端向网络侧设备发送第一消息,所述第一消息携带预测RLF发生时间的预测测量结果,从而网络侧设备能够通过该预测RLF发生时间的预测测量结果为终端提供合适的重配置,从而能够提高系统通信性能。
需要说明的是,相关技术规定了终端如何进行RLM测量以及RLF判断,以及触发RLF后的行为。其中,基于静态配置的计数器和定时器来进行RLF判断,等待定时器超时或计数器达到阈值的过程也会一定程度延长执行下一步动作的时间。
相关技术引入基于AI/ML辅助的移动性增强,其中包含基于AI/ML的RLF预测。引入基于AI/ML的RLF预测之后,如何对无线链路失败预测进行上报,包括上报的内容,预测变化时如何上报RLF预测变更,有待解决。
本申请实施例细化了RLF预测上报的内容,实现了RLF预测上报的变更,或释放,并给出了RLF预测上报相关的网络配置,如允许上报的细化指示,上报频度等。
在本申请实施例中,所述终端向网络侧设备发送第一消息,所述第一消息携带RLF预测的相关信息,这样,终端能够在发生RLF前向网络侧设备上报RLF预测的相关信息,能够及时处理可能的RLF,从而能够提高RLF处理效果。
可选地,所述终端向网络侧设备发送第一消息之前,所述方法还包括:
所述终端接收网络侧设备发送的第一配置信息,所述第一配置信息包括如下至少一项:

其中,所述第一配置信息用于指示所述终端是否上报与RLF预测关联的定时器的相关信息,从而在第一配置信息指示所述终端上报与RLF预测关联的定时器的相关信息的情况下,终端才会上报与RLF预测关联的定时器的相关信息;或,在第一配置信息指示所述终端不上报与RLF预测关联的定时器的相关信息的情况下,终端不上报与RLF预测关联的定时器的相关信息。

其中,所述第一配置信息指示第一门限,从而终端能够根据与RLF预测关联的定时器超时的预测概率是否达到第一门限判断与RLF预测关联的定时器是否会超时。以与RLF预测关联的定时器为T310为例,在预测T310超时的预测概率大于第一配置信息指示的第一门限时,预测T310会超时,终端可以向网络侧设备上报预测T310会超时。
其中,所述第一配置信息指示第二门限,从而终端能够根据RLC层的重传达到最大重传次数的预测概率是否达到第二门限判断RLC层的重传是否会达到最大重传次数。在RLC层的重传达到最大重传次数的预测概率大于或等于该第二门限时,终端预测RLC层的重传达到最大重传次数,终端可以向网络侧设备上报预测RLC层的重传达到最大重传次数;在RLC层的重传达到最大重传次数的预测概率小于该第二门限时,终端预测RLC层的重传不会达到最大重传次数。
其中,RLF预测的最大时长可以用于确定终端进行RLF预测的时间范围,或终端上报RLF预测的时间范围。
一种实施方式中,终端可以以执行用于RLF预测的AI推理的时间(如当前时间点)为时间起点,终端根据RLF预测的最大时长可以确定一个时间范围,作为终端进行RLF预测的时间范围。以RLF预测的最大时长为2s为例,终端预测未来2s之内是否会发生RLF。终端上报所述时间范围的RLF预测结果,能够避免上报时间范围外的预测结果,便于减少信令负荷。

一种实施方式中,终端可以在预测到会发生RLF时,开启第一定时器。在第一定时器超时的情况下,执行预测的RLF的恢复过程;或,在第一定时器超时的情况下,执行对应预测的RLF的重建立过程;或,在第一定时器超时的情况下,向网络侧设备发送第一消息,以上报RLF预测的相关信息。此时,第一定时器可以相比于预测的RLF发生时间具备一定的提前量,有助于辅助网络来处理RLF。示例地,预测的RLF发生时间为当前时间10s后,第一定时器的时长可以设置为8s,为网络预留2s来处理预测的RLF。
一种实施方式中,终端可以在向网络侧设备发送第一消息时,开启第一定时器。在接收到网络侧设备的重配置时,关闭第一定时器。从而通过第一定时器监测网络侧设备的重配置。

预测的随机接入失败的概率的变更内容;
预测无线链路控制RLC层的重传达到最大重传次数的概率的变更内容;
预测RLF发生时间的预测测量结果的变更内容。
另外,第一消息和第二消息可以均为RLF预测报告对应的消息。从而终端能够通过新的RLF预测报告替代旧的RLF预测报告。
一种实施方式中,所述RLF预测的相关信息的变更内容可以包含空的参数,表示释放之前上报的RLF预测的相关信息。以RLF预测结果的变更内容为例,终端可以在第二消息中指示释放前一次上报的RLF预测的相关信息或指示释放最新上报(不包括本次)的RLF预测的相关信息,该前一次上报的RLF预测的相关信息可以为第一消息中上报的RLF预测的相关信息,例如可以在第二消息中上报RLF预测结果为空,网络侧设备可以根据第二消息忽略前一次上报的RLF预测结果。
需要说明的是,释放所述第一消息中的RLF预测的相关信息,可以是进行RLF预测缓解。
该实施方式中,所述终端向网络侧设备发送第二消息,从而能够通过第二消息实现RLF预测上报的变更。
可选地,所述方法还包括:
所述终端接收网络侧设备发送的第二配置信息,所述第二配置信息包括如下至少一项:
第七指示信息,用于指示禁止定时器的时长;
第八指示信息,用于指示上报RLF预测的相关信息的上报频度;
第九指示信息,用于指示RLF预测的推理频度;
其中,在所述禁止定时器的运行期间不允许所述终端上报所述RLF预测的相关信息。
其中,终端可以在上报RLF预测的相关信息后,开启所述禁止定时器。示例地,终端可以在首次上报RLF预测的相关信息后,开启所述禁止定时器。在连接状态下的第一次上报为首次上报,禁止定时器未运行时,允许终端第二次上报,并开启禁止定时器。在所述禁止定时器未运行时,终端被允许上报RLF预测的相关信息,从而能够节省信令负荷。
另外,所述上报频度可以是指两次上报RLF预测的相关信息之间的最小时间间隔,比如1s内最多只能上报一次,以减低信令开销,有利于节省信令负荷。
另外,RLF预测的推理频度,可以是指用于RLF预测的AI模型的推理频度。推理频度可以理解为两次推理之间的时间间隔,即隔一定的时间长度后执行下一次推理。通过网络侧指示RLF预测的推理频度,避免终端推理频度过高,有助于终端节能。
可选地,所述终端向网络侧设备发送第一消息之后,所述方法还包括:
所述终端接收所述网络侧设备发送的重配置信息。
其中,所述重配置信息可以携带在切换消息或RRC重配置消息中。所述重配置信息可以包括用于终端重新选择小区的配置信息,示例地,可以包括候选小区或条件切换候选小区的信息。终端可以基于重配置信息执行RRC重配置过程,例如切换,或条件切换等。
一种实施方式中,所述终端向网络侧设备发送第一消息,包括:
终端执行RLF预测,进行RLF预测上报。终端上报RLF预测的相关信息,包括以下至少一项:
(1)RLF预测结果,指示RLF预测为真或假。进一步,UE仅在RLF预测结果为真时上报RLF预测结果。
(2)指示T310或T312开启状态的信息,用于指示T310或T312是否开启。考虑RLF预测时T310或T312可能未开启,或已开启两种情况:
如果T310或T312未开启,RLF预测是一种对于out-of-sync超前的预测,或者基于其他RLF失败原因如RLC重传达到最大次数的预测,便于网络提前作处理;
如果T310或T312已经开启,通过上报T310或T312开启状态信息,便于让网络基于RLF预测结果来处理。如果RLF预测为真且T310或T312已开启,则尽快处理,提高处理效率,提升通信性能。
(3)指示预测T310或T312是否超时的信息。预测T310或T312是否超时,进一步地,UE仅在预测T310或T312超时时上报该信息。
(4)T310或T312超时的概率。一种实施方法,所述概率用百分数表示,便于辅助网络决策如何配置UE。
(5)T310或T312剩余时长。如果T310或T312已经开启,上报运行Timer T310或T312的剩余时长,可以结合RLF预测的概率,用来辅助网络确定是否重配置UE,来改善UE的无线链路。
(6)指示第一定时器是否已开启,或指示第一定时器是否被使用的信息。所述第一定时器用于监测预测的无线链路失败。例如,如果通过测量报告消息(MeasurementReport)来上报预测结果,UE指示使用了第一定时器(used),或第一定时器已开启。从而隐式指示了该测量报告包含了RLF预测结果。
(7)第一定时器的时长。该时长可以基于秒,系统帧号(System frame number,SFN),时隙(slot)或OFDM符号(symbol)等单位来表示。
其中,如果预测会发生RLF,UE开启第一定时器。UE根据预测的RLF时间点来确定第一定时器时长。例如:
第一定时器时长=当前时间距预测的RLF时间点的时长–第一偏移量。
其中,第一偏移量表示相对于预测RLF发生的时间点的时间提前量,用于提前处理可能的RLF。第一偏移量可以为0。
(8)预测随机接入失败的概率。例如,UE预测在载波聚合CA或MR-DC小区组cell group的服务小区上随机接入失败的概率。UE预测SCG上随机接入失败的概率,通过MCG上报该RLF预测内容;或,UE预测MCG上随机接入失败的概率,通过SCG上报该RLF预测内容。
(9)预测RLC层的重传达到最大重传次数的概率。即预测RLF ARQ会达到最大次数导致的RLC失败的概率。
可选地,RLF预测结果在测量报告(MeasurementReport)或UE辅助信息(UE Assistance Information,UAI)消息中携带。
进一步地,UE在Cell group进行RLF预测上报或向目标网络节点进行RLF预测上报。目标网络节点包括主节点MN或辅节点SN。Cell group包括主小区组(Master cell group,MCG)或辅小区组(Secondary Cell group,SCG)。可以理解,RLF预测是按cell group分别进行的。
可选地,终端在上报RLF预测结果之前接收网络的第一配置(即第一配置信息),第一配置包括以下至少一项:
(1)按Cell group指示UE上报RLF预测结果的指示信息;所述Cell group包括主小区组MCG,辅小区组SCG。即UE在被允许上报RLF预测结果时才会上报RLF预测结果,与网络的能力或需求一致。
(2)是否上报T310或T312相关信息的指示信息。所述T310或T312相关信息包括以下至少一项:
T310或T312开启状态信息;
T310或T312剩余时长;
T310或T312超时的预测,预测结果包括真或假,或预测的概率值;
RLC层的重传达到最大重传次数的预测,预测结果包括真或假,或预测的概率值;
用于判断T310或T312超时的概率门限,该概率门限用于判断是否上报T310或T312超时,例如,T310或T312超时的预测结果超过该概率门限,则UE上报T310或T312预测超时;
用于判断RLC层的重传达到最大重传次数的概率门限,例如,RLC层的重传达到最大重传次数的预测结果超过该概率门限,则UE上报预测RLC层的重传达到最大重传次数。
(3)是否上报第一定时器相关信息的指示信息。
另外,所述第一定时器相关信息包括以下至少一项:
第一定时器开启状态,包括已开启、正在运行或未运行。
第一定时器时长,即网络配置第一定时器的时长,进一步地,如果终端被配置了第一定时器时长,终端被允许发送所述RLF预测结果。
(4)RLF预测的最大时长。这是UE上报RLF预测的时间范围,UE上报所述时间范围的RLF预测结果,能够避免上报时间范围外的预测结果,便于减少信令负荷。
一种实施方式,RLF预测的最大时长可以用于设置第一定时器时长。示例地,第一定时器时长可以为RLF预测的最大时长。
进一步地,所述第一配置可以是按Cell group配置的。Cell group包括主小区组MCG或辅小区组SCG。
所述第一配置可以为RRC重配置消息或系统消息。
相关技术存在如下问题:RLF预测需要有一定的时间提前量,用于基站做准备,比如测量、切换准备等工作,比如UE在图6中的P点(预测RLF的时间点)时可以向基站上报,但是这可能增加RLF预测不准确的概率。例如,此次UE的移动路径偏移常用的移动路径,预测是按常用的移动路径推断,会导致预测不准确。在出现预测不准确的情况下,基站执行的切换等操作是无效的(比如,将UE从cell1切换到cell2),甚至可能使得UE的通信性能变差。
在该实施例中,UE通过AI模型预测到将来的时间点t1会发生RLF,在上报RLF预测报告给基站后,UE可以变更或释放该预测报告。
一种实施方式中,如图7所示,所述终端向网络侧设备发送第一消息,包括:
终端执行RLF预测后,上报第一RLF预测报告。
终端继续执行RLF预测后,上报第二RLF预测报告。
所述第二RLF预测报告中的预测结果用于指示以下至少一项:
(1)对第一RLF预测报告中的预测结果的变更。变更项包括预测RLF发生的时间点或RLF发生的概率等部分或全部。以预测RLF发生的时间点为例,UE预测到将来的时间点t1会发生RLF,在上报RLF预测报告给基站后,UE预测仍会发生RLF,但是不再是t1时间点,而是t2时间点,t2相对于t1可以提前或延后。由于UE预测仍会发生RLF,UE可以发送一个新的RLF预测报告,指示新的时间点,基站可以总是以新的RLF预测报告为准。
(2)指示释放第一RLF预测报告。
(3)指示RLF预测缓解。如果UE后续的预测不会再发生RLF,则UE需要上报RLF预测缓解,可以是一个新的消息,也可以采用上报距离发生RLF的时间点的时长(假如上报的是多长时间后发生RLF)为无穷大来指示RLF预测解除。
进一步地,新的RLF预测报告替代旧的RLF预测报告。即:
终端包含空的参数表示释放之前上报的参数信息;或
基站接收到RLF预测报告后,释放或忽略之前接收到的RLF预测报告。即总是以新的RLF预测报告为准,也就是,总是覆盖旧的预测报告。
可选地,在上报RLF预测报告之前,UE接收网络发送的配置信息,该配置信息指示以下至少一项:
禁止定时器时长(Prohibit timer)。UE在首次上报RLF预测报告后,开启所述禁止定时器。UE在所述禁止定时器未运行,或首次上报时,UE被允许上报RLF预测报告,从而能够节省信令负荷。
上报频度,用来指示两次上报之间的最小时间间隔。比如1s内最多只能上报一次,以减少信令开销,有利于节省信令负荷。
推理频度,用来指示限定AI模型的推理频度,有助于UE节能。
上述禁止定时器时长、上报频度或推理频度也可以由协议约定。
本申请实施例可用于LTE,NR或6G等。
相较于相关技术,本申请实施例基于RLF预测的场景提供了更为精准的上报结果,场景包括RLF定时器T310/T312是否运行,RLC失败,上报结果的变更或释放等,提供了对应的上报方式和配置,有利于对RLF预测进行精准上报和准确处理,能够提升通信性能。
