Description

一种无线链路监测方法及 UE 技术领域 本发明实施例涉及通信技术领域,尤其涉及一种无线链路监测方法及 UE。 背景技术
无线链路监测(Radio Link Monitoring, RLM)指的是用户设备 (User
Equipment, UE)在物理层监测服务小区的下行无线链路质量, 以便向高层指示 同步 (In-Sync, IN)或失步 (Out-Of-Sync, OOS)状态。 UE基于参考信号对下行 链路质量进行估计, 并且与门限值 2。u^oein进行比较。 当估计的无线链路质量 比门限 β。 差时, 判定为失步状态; 当估计的无线链路质量比门限^好时, 判 定为同步状态。 门限值 β。ώ定义为 UE不能对下行无线链路进行可靠接收时的 下行无线链路质量水平, 相当于假定条件下下行控制信道传输的误块率 (Block Error Ratio, BLE )为 10%; 门限值 βιη定义为 UE可以对下行无线链路进行有 效可靠接收时的下行无线链路质量水平,相当于假定条件下下行控制信道传输 的误块率为 2%。
目前第三代合作伙伴计划 (3rd Generation Partnership Project, 3GPP ) 中 成立了一个新的工作组 (Work Item, WI), 引入了单天线接收的低成本及覆盖 增强的机器类通信(Machme-Type Communication, MTC ) UE。 而现有的协议 中, 对于无线链路监测的需求都是针对双天线接收的 UE, 对于单天线接收的 低成本及覆盖增强的 MTC UE并没有相关的定义及研究。
现有技术中, 对双天线接收的 UE进行无线链路监测方法请参阅图 8, 在 图 8中, UE在物理层每隔一段时间 vr需要对服务小区的下行链路质量进行一 次监测, 即 UE的物理层需要在 Τ。 , Τα+ι, Τη+2 , 时刻监测服 务小区的下行链路质量。 UE对某个时刻的无线链路质量的评估则是基于时间 窗7^ uate内的无线链路质量得到的。 例如, UE在7^时刻需要对 [τ。, 时间段 内的下行链路质量进行评估, 获得7 ^时刻对应的链路质量评估结果; UE在7^ 时刻需要对 [ τι, ^+1]时间段内的下行链路质量进行评估, 获得 +1时刻对应的 链路质量评估结果。
在协议 TS36.213中对评估时间间隔 (图 8中的 ) 定义到: 在非连续接收(Discontinuous Reception, DRX )模式下, UE物理层需要 在每个 DRX周期内对下行链路质量进行一次评估,即评估时间间 Ρ ΔΤ=1 DRX 周期;
在 non-DRX模式下, UE物理层需要在每个无线帧内对下行链路质量进行 一次评估, 即评估时间间隔 AT=10ms;
在协议 TS36.133中对于评估时间窗的长度 (图 8中所示 ^au^ ) 定义到: 在 DRX模式下, 同 /失步评估时间窗取决于 DRX周期长度。
在 non-DRX模式下, 对于失步监测, 评估时间窗长为 200ms;
在 non-DRX模式下, 对于同步监测, 评估时间窗长为 100ms;
初始时, 链路连接正常, UE物理层需要进行失步监测。 当下行链路质量 评估结果比门限值 2。"t差时, UE物理层需要给 UE高层上报失步指示。 当 UE 高层收到连续 N310个失步指示后, UE需要开启计时器 T310, 在计时器 T310 开启期间, 当下行链路质量评估结杲比门限值 好时, UE物理层需要给 UE 高层上报同步指示。
若在计时器 T310超时之前, UE高层收到连续 N311个同步指示 (如图 9 所示), 则说明下行链路恢复正常, UE关闭计时器 Τ310。
若在计时器 T310超时之前, UE高层没有收到连续 N311个同步指示(如 图 10所示), 则发生了无线链路失败, UE需要向服务小区发送无线链路失败 指示。
图 9 和图 10 中所示的发送两个连续的同 /失步指示消息的最小时间间隔 为:
DRX模式下, 最小时间间隔为一个 DR 周期;
non-DRX模式下, 最小时间间隔为 10ms。
即现有协议中要求到, 对于双天线接收的 UE, 在 non-DRX模式下 UE物 理层在每个无线帧内都进行一次下行链路质量的评估, 即每 10ms进行一次链 路质量估计。 而对于低成本 MTC UE来讲, 其中一个最主要的需求就是 "最 低成本 (Lowest Cost)"。 然而, 如杲将 10ms这样的一个评估周期直接用于低成 本 MTC UE, 则必然带来过多的功率消耗, 与该 WI的主要目标 "最低成本" 是相违背的, 因此, 有必要提供一种新的监测方法解决上述问题。

本发明实施例提供了一种无线链路监测方法及 UE , 能够降低功率消耗, 节省设备成本。 由于 UE处于 DRX模式时,监测过程中涉及的相关时间由 UE 的 DRX周期决定, 因此, 以下实施例主要针对 UE处于 non-DRX模式进行描 述。
请参阅图 1 , 本发明无线链路监测方法一个实施例包括:
101、 UE 在物理层采用扩展的链路监测周期监测服务小区的下行链路质 量, 扩展的链路监测周期大于原始的链路监测周期;
本实施例中, 原始的链路监测周期为现有协议中规定的对双天线接收的 UE进行无线链路质量监测时所使用的链路监测周期, 如背景技术所述, 原始 的链路监测周期可以为 10ms。 具体在本实施例中, 所采用的链路监测周期为 扩展的链路监测周期, 扩展的链路监测周期要大于 10ms。
102、 UE在监测结果满足预设的上报条件时, 向 UE的高层发送同步指示 消息或失步指示消息。 具体实现中, 预设的上报条件可由 UE预先设置, 例如: 当监测结果低于 门限值 e。ut时, 向 UE的高层发送失步指示消息; 当监测结果高于门限值 时, 向 UE的高层发送同步指示消息。 门限值 e。ut定义为 UE不能对下行无线链路 进行可靠接收时的下行无线链路质量水平,相当于 ^定条件下下行控制信道传 输的误块率 (Block Error Ratio, BLER)为 10%; 门限值 ¾n定义为 UE可以对下 行无线链路进行有效可靠接收时的下行无线链路质量水平,相当于假定条件下 下行控制信道传输的误块率为 2%。
下面以一个具体实施例对本发明的无线链路监测方法进行描述。
通常无线链路监测包括失步监测和同步监测, 在初始状态下, 无线链路通 常会处于同步状态, 所以需要先做失步监测。
具体可参见图 2, 本实施例中, 采用的链路监测周期为扩展的链路监测周 期, 用 ^表示, Λ ^大于 10ms, 即每隔 ^ms UE在物理层对服务小区的下行链 路质量进行一次监测。 如图 2所示, UE物理层需要在 1。, 、 , …^, tm+i, tm+2, ... tn, tn+i , +2时刻对服务小区的下行链路质量进行监测, 相邻两次监 测的时间间隔为 !^。 由于此时需要做失步监测, 因此需要对采用扩展的链 路监测周期 在第一扩展时间窗内监测到的服务小区的下行链路质量进行评 估以得到监测结杲, 本实施例中, 第一扩展时间窗用 w2表示, w2大于 200ms。 例如, 当要获取 时刻的监测结果时, 就需要对 [1。, t- ]时间段内监测到的下 行链路质量进行评估得到监测结果, 当监测结果比门限值 t差时, UE物理层 给 UE高层上报失步指示消息。 当 UE高层收到连续 N310个失步指示消息后, 需要进行同步监测。
在进行同步监测时, UE需要开启计时器 T310。 具体的监测方法为: 对采 用扩展的监测周期 Μ在第二扩展时间窗内监测到的服务小区的下行链路质量 进行评估以得到监测结果, 本实施例中, 第二扩展时间窗用 ^表示, W3大于 lOOmSo 在计时器 T310开启期间, 若得到的监测结果比门限值 ¾n好, 则 UE 物理层需要给 UE高层上报同步指示消息。
若在计时器 T310超时之前, UE高层收到连续 N311个同步指示消息, 则 说明下行链路恢复正常, UE关闭计时器 T310。
若在计时器 T310超时之前, UE高层没有收到连续 N311个同步指示消息, 则发生了无线链路失败, UE需要向服务小区发送无线链路失败指示消息。 另外, 本实施例中, UE物理层向高层发送两个连续的同步指示消息或失 步指示消息的最小时间间隔为扩展的最小时间间隔 , 如图 3 所示, 扩展的 最小时间间隔 大于原始的最小时间间隔 I0ms。
具体实现中, UE可以在每次监测结果满足预设的上报条件时, 即监测结 果大于 或小于 β。《时, 都向 UE的高层发送同步指示消息或失步指示消息, 也可以连续监测 Ν次( Ν可预先设定), 当连续 Ν次的监测结杲相同且均满足 预设的上报条件时, 只向 UE的高层发送一次同步指示消息或失步指示消息, 以进一步节省功率消耗。
具体实现中, 上述 、 Ν2 . Ν ^可由 UE预先自行设定, 例如, 在协 议 TS36.213和 TS36.133中,对低成本 MTC UE的无限链路监测操作相关参数 进行定义。
另外, 上述四个参数也可由网络侧设备(例如基站 e B )根据 UE发送的 设备类型指示消息进行设置, 然后通过无线资源控制 (Radio Resource Control , RRC ) 消息通知给 UE。 UE向网络侧设备发送设备类型指示消息的 具体实现过程可如下:

另外需要说明的是, 本实施例中, 以链路监测周期改变时, 监测时间窗也 随之改变为例进行说明, 在实际应用中,监测时间窗也可以不随着链路监测周 期的改变而改变。
例如: 现有技术中, 每隔 10ms进行一次链路质量监测, 在进行失步监测 时, 所采用的时间窗为 200ms, 即取距离当前某一时刻 200ms 内所监测到的 20 个数据对当前某一时刻的链路质量进行评估, 在进行同步监测时, 所采用 的时间窗为 100ms, 即取距离当前某一时刻 100ms内所监测到的 10个数据对 当前某一时刻的链路质量进行评估。 具体在本实施例中, 将链路监测周期增大 了, 例如每隔 20ms进行一次链路质量监测, 对应地, 失步监测时间窗可以取 400ms, 那么对某一时刻的链路质量进行失步评估时, 所取数据的数量就还是 20 个, 同步监测时间窗可以取 200ms, 对某一时刻的链路质量进行同步评估 时, 所取数据的数量还是 10个, 这样就保证了在不损失监测结果准确度的情 况下节省功率消耗。 当然, 也可以在链路监测周期为 20ms的情况下, 失步监 测时间窗依然取 200ms, 同步监测时间窗依然取 100ms, 这样评估时所取数据 的数量就会减少, 在一定程度上降低了监测结果的准确度, 但依旧能节省功率 消耗, 在实际应用中, 具体采用哪一种方法可依据实际情况决定, 此处不做具 体限定。
本实施例中, 由网络侧设备根据 UE发送的设备类型指示消息为 UE设置 扩展的链路监测周期, 第一扩展时间窗, 第二扩展时间窗及扩展的最小时间间 隔, 或者由 UE预先自行设定这些参数, 然后在物理层采用扩展的链路监测周 期监测服务小区的下行链路质量, 并在监测结果满足预设的上报条件时, 采用 扩展的最小时间间隔向 UE的高层发送同步指示消息或失步指示消息。本实施 例中, 由于采用了扩展的链路监测周期进行链路监测, 即增大了对无线链路进 行监测的周期, 降低了监测频率, 因此, 能够降低功率消耗, 节省设备成本。

为便于理解, 下面以一个实际应用场景对本实施例 UE的各单元之间的交 互方式进行描述, 本实施例主要以网络侧设备为 UE配置监测过程中所需的相 关参数为例进行说明, 具体如下:
首先, 发送单元 601向网络侧设备发送设备类型指示消息, 以请求网络侧 设备为 UE配置相关参数, 具体实现方式可如下:
-- ASN1 START
MachineTypelndication ::= SEQUENCE {
criticalExtensions CHOICE {
cl CHOICE {
machineTypelndication MachineTypelndication-IEs spare3 NULL, spare2 NULL spare 1 NULL criticalExtensionsFuture SEQUENCE {}

其中, 信令举例中的 "typel" "type2"可以指代设备类型, 例如智能抄表, 可穿戴设备等。
网絡侧设备根据该设备类型指示消息所标注的设备类型进行配置,并通过 RRC信令通知给 UE, 具体的实现过程可如下:

spare2, sparel },
}
}
-- ASN1STOP
其中, 信令举例中的 "evaluation-period"、 "OOS-period"、 "IN-period"、
"MinReport-period"分别对应于扩展的链路监测周期 ^、第一扩展时间窗 ^、 第二扩展时间窗 ^、 扩展的最小时间间隔 , 接收单元 602接收网络侧设备 配置的这些参数。
监测单元 603 采用扩展的链路监测周期 Νι对服务小区的下行链路质量进 行监测。 通常无线链路质量监测包括失步监测和同步监测, 在初始状态下, 无 线链路通常会处于同步状态, 所以需要先做失步监测。
如图 2所示, 在进行失步监测时, 第一监测单元 6031每隔 ^ms在物理层 对服务小区的下行链路质量进行一次监测,即第一监测单元 6031需要在 , 、 χ2 , tm+1, tm+2 , ... tn, tn+1, tn+2时刻对服务小区的下行链路质量进行监 测, 相邻两次监测的时间间隔为 Wi ms, Νι大于 10ms。 由于此时需要做失步监 测, 因此第一监测单元 6031需要对釆用扩展的链路监测周期 ^在第一扩展时 间窗内 W2监测到的服务小区的下行链路质量进行评估以得到监测结杲, ^大 于 200ms。 例如, 当要获取 tn时刻的监测结果时, 就需要对 [ , ]时间段内 监测到的下行链路质量进行评估得到监测结果,当监测结果比门限值 β™'差时, 发送单元 601给 UE高层上报失步指示消息。 当 UE高层收到连续 N310个失 步指示消息后, 第二监测单元 6032需要进行同步监测。
在进行同步监测时, 第二监测单元 6032需要开启计时器 Τ310。 具体的监 测方法为: 对采用扩展的监测周期 在第二扩展时间窗 内监测到的服务小 区的下行链路质量进行评估以得到监测结果, N3大于 100ms。在计时器 T310 开启期间, 若得到的监测结果比门限值 好, 则发送单元 601 需要给 UE高 层上报同步指示消息。
若在计时器 T310超时之前, UE高层收到连续 N311个同步指示消息, 则 说明下行链路恢复正常, 第二监测单元 6032关闭计时器 T310。
若在计时器 T310超时之前, UE高层没有收到连续 N311个同步指示消息, 则发生了无线链路失败,发送单元 601需要向服务小区发送无线链路失败指示 消息。
另外, 本实施例中, 发送单元 601向 UE的高层发送两个连续的同步指示 消息或失步指示消息的最小时间间隔为扩展的最小时间间隔 , 如图 3所示, 扩展的最小时间间隔 大于原始的最小时间间隔 10ms。
具体实现中, 发送单元 601可以在每次监测结杲满足预设的上报条件时, 即监测结杲大于 或小于 δ。《时, 都向 UE的高层发送同步指示消息或失步指 示消息, 也可以连续监测 Ν次( Ν可预先设定), 当连续 Ν次的监测结果相同 且均满足预设的上报条件时, 只向 UE的高层发送一次同步指示消息或失步指 示消息, 以进一步节省功率消耗。
另外需要说明的是, 本实施例中, 以链路监测周期改变时, 监测时间窗也 随之改变为例进行说明, 在实际应用中,监测时间窗也可以不随着链路监测周 期的改变而改变。
例如: 现有技术中, 每隔 10ms进行一次链路质量监测, 在进行失步监测 时, 所采用的时间窗为 200ms, 即取距离当前某一时刻 200ms 内所监测到的 20 个数据对当前某一时刻的链路质量进行评估, 在进行同步监测时, 所采用 的时间窗为 100ms, 即取距离当前某一时刻 100ms内所监测到的 10个数据对 当前某一时刻的链路质量进行评估。 具体在本实施例中, 将链路监测周期增大 了, 例如每隔 20ms进行一次链路质量监测, 对应地, 失步监测时间窗可以取 400ms, 那么对某一时刻的链路质量进行失步评估时, 所取数据的数量就还是 20 个, 同步监测时间窗可以取 200ms, 对某一时刻的链路质量进行同步评估 时, 所取数据的数量还是 10个, 这样就保证了在不损失监测结果准确度的情 况下节省功率消耗。 当然, 也可以在链路监测周期为 20ms的情况下, 失步监 测时间窗依然取 200ms, 同步监测时间窗依然取 100ms, 这样评估时所取数据 的数量就会减少, 在一定程度上降低了监测结杲的准确度, 但依旧能节省功率 消耗, 在实际应用中, 具体采用哪一种方法可依据实际情况决定, 此处不做具 体限定。
本实施例中, 由网络侧设备根据发送单元发送的设备类型指示消息为 UE 设置扩展的链路监测周期, 第一扩展时间窗, 第二扩展时间窗及扩展的最小时 间间隔,然后监测单元在物理层采用扩展的链路监测周期监测服务小区的下行 链路质量, 并在监测结果满足预设的上报条件时, 由发送单元采用扩展的最小 时间间隔向 UE的高层发送同步指示消息或失步指示消息。 本实施例中, 由于 釆用了扩展的链路监测周期进行链路监测,即增大了对无线链路进行监测的周 期, 降低了监测频率, 因此, 能够降低功率消耗, 节省设备成本。
