Description

无线链路管理方法及装置 技术领域
本申请涉及但不限于通信领域，尤指一种无线链路管理方法及装置。
背景技术
在未来的第三代合作伙伴计划的第五代(3rd Generation Partnership Project fifth Generation，简称为3GPP 5G)全新设计的新无线接入(New RAT/Radio，简称为NR)系统中，高频段无线载波资源利用和操作将扮演着越来越重要的角色，通过载波聚合和紧耦合多连接等方式，可以将更宽阔的高频载波资源充分地聚合利用，以提高NR系统容量和吞吐率性能。如图1所示，在低频宏基站小区的广覆盖下，运营商可以对部分热点Hotspot区域Hotspot通过高频(mmWave)小基站小小区进行容量增强。和传统全向式(Omni-Directional)或者扇区式(Sector)小区覆盖不同，高频小小区为了增加上下行无线覆盖和信道性能，通常TX/RX侧需要进行波束成形(Beamforming)操作，即通过多天线相位技术，将波束定向发射/定向接收，这样可以汇聚发射功率/减少干扰。图1中的发送接收节点簇TRP Cluster就是以多个Beams(波束)形式来发射信号的。
在图1中的波束成形(Beamforming，简称为BF)高频通信基站小小区的部署方式，可以映射到图2所示的高低频通信基站做紧耦合多连接的数据传输架构。图2中基站和用户设备(User Equipment，简称为UE)的空中接口细箭头线表示Uu口控制面信令，粗箭头线表示用户面数据。低频宏基站服务小区提供基本的无线覆盖，BF模式的高频小基站提供数据分流，当UE在同一宏基站服务小区内移动的时候，会发生高频微基站间的切换或者更多连接的数据传输。
以过去通用移动通信系统/长期演进(Universal Mobile Telecommunications System/Long Term Evolution，简称为UMTS/LTE)系统为例，由于主要工作在低频段(<6GHz)，因此对应基站的发送接收点(Transmit Receive Point，简称为TRP)通常采取全向(Omni-Directional)和 扇区(Sector)方式发收模式，因此对应的下行公共信道/信号有着较广阔的覆盖区域，即当终端设备UE进入到以发送接收点TRP为圆心的特定半径之内，就可以在任意的时间/地点/方向上接收到下行公共信道/信号，实现下行时频同步，小区发现驻留，系统消息读取，上行随机接入，导频测量等基本操作。
由于高频段信道的路损(Path loss)和衰减相当严重，为了以小发射功率来实现远距离覆盖和空间/时频信号干扰隔离，NR高频基站TRP通常采取波束成形Beamforming的发收模式，因此对应的下行公共信道/信号有着较狭窄的覆盖区域(对应着的服务小区比较狭长状)，即当UE进入到以TRP为圆心的特定半径之内，只能在特定的时间/地点/方向上通过空间搜索(Spatial Search)才能接收到下行公共信道/信号，以实现上述基本功能。随着UE在水平和垂直方向上的移动，UE容易脱离Beams的覆盖，称为空间/时频失步(假设TRP/UE不能实现快速的彼此Beam跟踪)，空间/时频失步之后相当于UE进行到弱覆盖区域，不能有效维持上下行时频同步/上行随机接入/高效数据传输，因此UE必须尽快重新搜索测量到合适的小区/Beam等，恢复空间/时频同步状态。
假设TRP节点内只有一个波束成形链(RF chain)，TRP采取周期环形扫射的方式发射任何下行信道/信号。当UE成功跟踪并且驻留在高频波束成形Beamforming某服务小区中，如果有数据传输的需求，UE需要先和TRP建立无线链路(Radio Link，简称为RL)，进入到无线资源控制连接(Radio Resource Control_CONNECTED，简称为RRC_CONNECTED)模式。随后TRP会为UE分配专有的时频资源，基于调度方式的进行上下行数据块传输。
下行方向，UE一方面需要通过TRP发射的下行公共同步信号来保持空间/时频/时频的最佳跟踪状态，另一方面UE需要通过TRP发射的下行专有参考信号来测量和反馈信道状态信息(Channel State Information，简称为CSI)。
上行方向，TRP一方面需要通过UE发射的上行公共同步信号来保持空间/时频/时频的最佳跟踪状态，另一方面TRP需要通过UE发射的上行专有 参考信号来测量CSI。
从本意上，上下行专有参考信号是用来进行专有信道的测量和/或解调的，但是否也可以服务于波束Beam跟踪的目的，即下行方向，UE是否可以只监听接收TRP发射的下行专有参考信号，来保持下行空间/时频/时频的最佳跟踪状态；上行方向，TRP是否可以只监听接收UE发射的上行专有参考信号，来保持上行空间/时频/时频的最佳跟踪状态。当发生无线链路失败(Radio Link Failure，简称为RLF)的时候(比如遭遇阻塞Blockage或者遮蔽Deafness)，UE上下行自动进入空间/时频/时频失步子状态(但仍然是RRC_CONNECTED模式)，此时UE仍然需要在空间/时频失步点附近继续监听源服务TRP的下行专有参考信号，而源TRP仍然需要在空间/时频失步点附近继续监听上行专有参考信号，从而UE努力快速恢复和源服务TRP之间的波束同步子状态。如果UE无法在特定时间内恢复波束同步子状态，那么UE需要先退出RRC_CONNECTED状态，重新监听接收源服务TRP和其它相邻TRP的下行公共信道/信号，此时UE可以驻留到其它相邻TRP的服务小区中，再重新建立专有RL。
以下行方向为例，当TRP发射BF同步训练信号的时候，开始是按照特定离散的角度环扫发射的(比如水平0,30,60,90,120,….360度这样的规律)，而UE也可能按照特定离散的角度定向接收。经过初步的“粗同步训练”之后，TRP和UE大致能够确定对方的最佳离散角度，之后可以进一步进入“细同步训练”阶段，使得TRP和UE能够更加精准地确定对方的连续角度(“细同步训练”的水平角度调整粒度比之前环扫发射的离散角度要小)，细同步训练使得路损Pathloss最小。之后随着UE的移动，TRP和UE需要根据对方发射的BF同步训练信号，继续不断微调发射和接收的角度。上述过程如图3所示。
“细同步训练”是基于通信节点硬件本地实现的可选优化功能，在“细同步训练”完成之后，TRP和UE侧才能保证波束干扰信号(Beam Reference Signal.，简称为BRS)的最佳无线资源管理(Radio Resource Management，简称为RRM)测量结果和最可靠的测量精度，和无线链路(Radio Link，简称为RL专有信号的最佳接收解调性能结果，因此可以处 于最佳RRM测量模式和数据传输模式，此时TX端信号发射效率和RX端接收的信噪比最大；否则根据仿真显示，如果空间/时频同步训练的精度结果不够，接收信噪比将减小，TRP和UE之间不能处于最佳RRM测量模式和数据传输模式，甚至更坏的情况TRP和UE之间发生空间/时频失步，它们只能处于最差的RRM测量模式和数据传输模式。因此为了保证UE对做波束成形通信基站下行参考信号的RRM测量质量和精度，UE对目标BF通信基站所辖的Beams建立并且维持“粗(细)同步子状态”，否则测量获得的RRM测量结果不准确和不可靠。
在做多连接数据传输模式的UE移动过程中，非BF模式的锚点通信基站，通常需要基于UE的RRM测量上报结果，为UE选择和配置最好的目标BF模式分流基站TRP，或做TRP间的移动切换，或者增加配置更多的TRP，进行更多连接的数据传输。按照LTE RRM测量评估模型，如图4所示：针对某个特定的测量对象(LTE目标小区或者TRP下的Beam)和测量评估量，A为UE根据内部实现而测量得到的初步测量采样值，B为UE在一定的采样周期内，通过层1过滤器(Layer 1Filtering)模块层1过滤处理后而获得的中间测量采样值，C为UE在一定的采样周期内，通过层3过滤器(Layer 3Filtering)模块层3过滤处理后而获得的动态分析评估值，C’为对比分析评估值(和C有相同的测量评估量纲)，D为UE在Measurement Report测量上报消息测量报告(Measurement Report，简称为MR)中上报的内容结果值。旧RRM测量模型中，层3过滤处理模块和评估和上报准则(Evaluation of reporting Criteria)模块的行为和参数使用方式都是被LTE协议标准化的，相关的配置参数来自RRC空口消息的配置信令。
当前LTE协议已经为不同的移动切换和多连接配置操作目的，定义了多种RRM测量事件类型，比如事件A1(Event A1)表示：UE对当前LTE服务小区(可以是一个或多个)导频信号的强度(Reference Signal Receiving Power，简称为RSRP)或者质量参考信号接收质量(Reference Signal Receiving Quality，简称为RSRQ)的测量动态分析评估值结果(已经经过了层3过滤的处理)，和源基站eNB已经通过RRC空口信令配置的门限值(Thresh)相比较结果更好(中间还有一个神经缓冲偏移值Hys：)且持续 超过一段事件的触发时间TTT(time to trigger)，这样UE触发本地产生A1事件，触发MR上报；否则不能产生A1事件。其他各种Event事件的含义可以参考LTE协议。上述旧RRM测量模型和定义有如下特点：对于某种RRM测量事件，只是关联到某一个确定的源服务小区和/或某一个确定的相邻服务小区(Neighbour Cell)，形成1对1的小区测量对比评估配对Pair。
对于处于波束成形工作模式下的分流微基站TRP，其内部所辖的多个Beams工作特点方式和传统LTE基站内所辖的多个LTE服务小区有很大不同，如上面的背景技术中所述。如果沿用LTE RRM测量评估机制，当某个目标TRP 2所辖目标服务Beam对应的RRM测量结果明显好于某个源TRP 1所辖的源服务Beam，UE很可能会触发对应的某移动事件，并且通过MR消息上报给锚点控制宏基站。此后锚点控制宏基站会通过RRC重配消息，让UE建立和该目标TRP 2所辖目标服务Beam的无线连接RL(因为此目标服务Beam链路质量更好)，而删除UE之前和源TRP 1所辖源服务Beam的RL(因为此源服务Beam链路质量变差了)，该过程如图5所示。UE原本处于主基站宏服务小区MeNB和TRP 1某源服务Beam的双连接数据传输状态，后来由于UE移动，被锚点切换重配到MeNB和TRP 2某Beam的双连接数据传输状态。
由于每个分流基站TRP内通常配置且激活有多个服务Beams(以特定方式朝着不同物理方位扫射覆盖)，而UE会对不同的Beams进行上述的粗(细)空间时频跟踪同步尝试和相伴的RRM测量，以建立和维持在“粗(细)同步子状态”，从而获得较精准可靠的RRM测量结果，因此UE会频繁地在TRP内发生波束切换(Beam Switch)操作，即从同一TRP下的某个信号不好的Beam1，自动切换到另外的信号更好的Beam2上，这种特点使得单个Beam并不能完全反映出分流基站TRP的整体综合的无线覆盖服务质量好坏。举个例子，如果图5中TRP 2下有4个下行服务Beams，分别朝着不同的下行方位角发射同步和导频信号，UE虽然很容易对其中一个Beam3实现同步跟踪和进入“粗(细)同步子状态”，从而测得很好的RRM测量结果，但是如果TRP2下的其他Beam1/2/4相对都很差，从而UE不容易对它们实现跟踪同步上，从而不容易进入到“粗(细)同步子状态”，或者测得的 RRM测量结果也较差，那么TRP2其实可能并不是一个很好的目标TRP移动切换对象，因为一旦Beam3被空间/时频临时障碍物遮挡比如：发生Blockage，那么UE不得不尝试本地Beam Switch到其他较差的Beam1/2/4上，或者触发空口信令让主控锚点基站重配目标TRP，因此可能并不能获得较好的数据分流传输服务。

详述
下文中将参考附图并结合实施例来详细说明本申请。
需要说明的是，本申请的说明书和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。
实施例1
在本实施例中提供了一种无线链路管理方法，图6是根据本发明实施例的无线链路管理方法的流程图，如图6所示，该流程包括如下步骤：
步骤S602，接收基站通过无线资源控制RRC信令下发的无线资源管理RRM测量参数；
步骤S604，根据该RRM测量参数，对目标波束成形BF分流基站发送接收点TRP所辖的多个或者全部波束进行RRM测量，获得RRM测量结果；
步骤S606，基于多个或者全部波束联合评估该RRM测量结果，并根据评估结果从源BF分流基站TRP切换至目标BF分流基站TRP或者额外添加目标BF分流基站TRP。
在一实施方式中，在本实施例中，上述无线链路管理方法的应用场景包括但并不限于：波束成形基站间无线资源控制(Radio Resource Management简称为RRM)测量评估切换。在该应用场景下，终端UE接收基站通过无线资源控制RRC信令下发的无线资源管理RRM测量参数；根据该RRM测量参数，对目标波束成形BF分流基站发送接收点TRP所辖的多个或者全部波束进行RRM测量，获得RRM测量结果；基于多个或者全部波束联合评估该RRM测量结果，并根据评估结果从源BF分流基站TRP切换至目标BF分流基站TRP或者额外添加目标BF分流基站TRP。也就是说，在本实施例中，以每一TRP所辖的多个或者全部波束作为RRM测量粒度，因此，可以避免以单个波束为粒度进行无线资源控制测量评估并进行波束成形基站间移动切换所导致终端移动性能较差的情况，达到提高终端移动性能的效果。
下面结合示例，对本实施例进行举例说明。
本实施例的主要场景如图2所示：UE和非BF模式的主控锚点基站(可以是MeNB或者NR基站节点)已经建立了RRC信令连接SRB和若干个用 户面数据承载DRB(s)。主控锚点基站和若干个处于BF模式的分流基站TRP节点(主要是高频部署，但也不排除中低频基站施加BF操作的情况)通过通信基站间的标准化接口相互连接(可以是LTE X2或者NR Xnew接口)，因此可以将DRB(s)用户数据进行上下行的旁路用户数据分流和并行的多连接数据传输。
在UE和任何BF模式分流基站TRP建立无线链路RL之前(即还没有进入到多连接数据传输模式)，主控锚点基站通过RRC信令配置给UE相关的测量参数，UE基于这些参数，对目标BF分流基站TRP所辖的全部所有或者多个Beams(>1)进行下行空间/时频跟踪和同步和下行RRM测量，即UE先对Beams进行下行空间/时频同步训练和下行时频同步尝试，通过下行波束训练的过程，尝试找到目标TRP的公共下行信道/信号(包括下行空间/时频同步训练信号，BRS导频信号，系统广播消息信号等)的最佳发射角度和UE自己的最佳接收角度，继而进行下行RRM测量，获得各条目标服务Beams对应的精准RRM测量结果。
UE将各条目标服务Beams对应的RRM测量结果(如BRS导频的信号强度或者质量)采样记录下来，然后按照图7本发明实施例新的RRM测量评估模型进行评估操作，包括：
A1…An为UE针对同一目标TRP所辖的多个Beam1…Beam n测量得到的初步测量采样值(这些值可能是UE在“BF失步子状态”和/或“BF粗/细同步子状态”下测量得到的，因此有的可靠精准，有的不可靠不精准)，B1…Bn为UE在一定的采样周期内，通过Layer 1Filtering模块层1过滤处理后而获得的中间测量采样值(此时可以过滤掉一些不可靠不精准的采样值)，C1…Cf为UE在一定的采样周期内，通过Layer 3Filtering模块层3过滤处理后而获得的动态分析评估值。该层3过滤处理算法可以采取不同预定义的方式对输入的B1…Bn值进行各种算法加权处理，以体现反映出对应于Beam1…Beam n的整体综合评估值(如对BRS导频信号采样结果的加权平均强度或者质量值)，C1…Cf对应于采取不同层3过滤处理算法获得的整体综合RRM评估结果。C1’…Cf’为对比分析评估值(和C有相同的测量评估量纲)，D1…Df为UE在Measurement Report测量上报消息(MR) 中上报的RRM评估结果值，例如各种预定义的RRM事件等。本发明实施例的新RRM测量模型中，层3过滤处理模块和评估上报准则(Evaluation of reporting Criteria)模块的行为和相关参数使用方式都可以被NR新空口协议所标准化的，相关的配置参数来自RRC空口消息内的配置信令。
未来NR新协议可以为不同的移动切换目的，定义多种RRM测量事件类型，比如Event NR-A1事件表示：UE对目标BF分流基站TRP所辖的全部所有或者多个Beams(>1)的算术平均导频信号强度RSRP或者质量RSRQ的测量结果(已经经过了层3过滤的处理)，和主控锚点基站通过RRC空口信令配置的门限值Thresh相比较，结果更好于一个神经缓冲偏移值Hys值，且持续超过一段事件触发时间TTT：time to trigger，这样UE触发本地产生NR-A1事件，并且MR上报给主控锚点基站；否则不能产生NR-A1事件。再比如Event NR-A2事件表示：UE对目标BF分流基站TRP所辖的全部所有或者多个Beams(>1)的平均导频信号强度RSRP或者质量RSRQ的测量结果(已经经过了层3过滤的处理)，和源BF分流基站TRP所辖的全部所有或者多个Beams(>1)的平均导频信号强度RSRP或者质量RSRQ的测量结果相比较，结果更好且大于一个被配置的神经缓冲偏移值Hys，且持续超过一段事件触发时间TTT：time to trigger，这样UE触发本地产生NR-A2事件，触发MR上报给主控锚点基站；否则不能产生NR-A2事件。其他各种Event事件类型的含义可以根据需要，由NR新协议预定义。
上述新RRM测量模型和定义有如下特点：对于某种类型RRM测量事件，能关联到某一个确定TRP所辖的全部所有或者多个服务Beams(>1)和/或另外一个确定TRP所辖的全部所有或者多个服务Beams(>1)，形成n对m的Beams RRM测量，滤波处理，对比评估配对Pair，并且能够按照不同的层3过滤处理算法，同时产生多个并行的RRM事件结果，以供主控锚点基站移动性判决综合参考使用，从而能更合理地开启，更新，停止UE多连接数据传输操作，并且实时获悉被服务UE和协作做紧耦合的BF分流基站TRP侧的无线信号覆盖强度/质量等整体综合情况。
在一个实施方式中，基于多个或者全部波束联合评估该RRM测量结果包括以下步骤：
步骤S11，获取该目标BF分流基站TRP所辖的多个或者全部波束各自对应的RRM测量结果；
步骤S12，根据预定RRM测量结果评估模型对获取的该RRM测量结果进行联合评估操作。
通过上述步骤S11～步骤S12，根据预定RRM测量结果评估模型对获取的多个或者全部波束各自对应的RRM测量结果进行联合评估操作，使得UE能够被添加或者切换到无线覆盖服务质量整体综合面上更好的目标TRP上。
在一个实施方式中，根据预定RRM测量结果评估模型对获取的该RRM测量结果进行联合评估操作包括以下步骤：
步骤S21，将该目标BF分流基站TRP所辖的多个或者全部波束各自对应的RRM测量结果作为并行的初步测量采样值；
步骤S22，按照预定采样周期并行过滤该初步测量采样值，得到并行的中间测量采样值；
步骤S23，采用预定义方式对该并行的中间测量采样值进行加权平均处理，得到单一串行输出的联合评估值，并将该联合评估值和对比分析评估值按照预设不等式规则进行对比评估以得到对比评估结果，其中，该联合评估值和该对比分析评估值具备相同的测量评估量纲。
通过上述步骤S21～步骤S23，得到单一串行输出的联合评估值，进一步使得UE能够被添加或者切换到无线覆盖服务质量整体综合面上更好的目标TRP上。
在一个实施方式中，在得到联合评估值和对比评估结果之后，还包括以下步骤：
步骤S31，按照RRM测量结果上报评估准则上报联合评估值和对比评估结果。
在一实施方式中，按照RRM测量结果上报评估准则上报联合评估值和对比评估结果包括以下步骤：
步骤S41，判断该联合评估值和该对比评估结果是否满足预定义的 RRM测量事件，其中，该RRM测量事件是新无线接入系统NR空口协议所标准化定义的事件；
步骤S42，在判断结果为是或者满足预设条件集合的情况下，通过终端和主控锚点基站间的空中接口测量报告MR上报该评估结果。
通过上述步骤S41～S42，在联合评估值和对比评估结果满足预定义的RRM测量事件时，通过终端和主控锚点基站间的空中接口测量报告MR上报该评估结果，使得基站能够进行一些预配置操作。
在一实施方式中，上述RRM测量事件与一个确定TRP所辖的多个或者全部波束和/或另一确定TRP所辖的多个或者全部关联，以在RRM测量后产生多个并行的RRM测量采样结果。
下面结合示例，对本实施例进行举例说明。
实施例1
如图8所示，主要是UE原本处于和MeNB的单连接数据传输模式，后来由于UE移动进入到TRP1的覆盖之内，TRP1被添加配置给UE，进入到和MeNB和TRP 1的双连接数据传输状态。
下面对图8进行详细说明。
某运营商部署和利用了高低频紧耦合做双连接DC操作，在低频主控锚点基站MeNB所在的某授权载波上有Pcell的服务宏小区覆盖，在远端通过X2接口，连接SeNB高频分流基站TRP节点，SeNB节点所在某高频授权载波上有1个TRP1和所辖的4个服务Beams的部署，用于热点区域容量增强。
起始，UE仅仅处于Pcell的覆盖之下，因此仅仅和MeNB形成单连接操作。
随着UE移动，UE逐渐靠近Pcell+TRP-Beams的公共覆盖区域，从而MeNB决定为UE配置相关的高频目标服务TRP1节点的测量参数，让UE对目标TRP1-Beams进行下行RRM测量，默认地UE需要先对目标TRP1-Beams进行下行空间/时频跟踪同步尝试。非BF低频MeNB节点和BF高频SeNB-TRP1节点和UE都支持本发明实施例的内容能力。本发明实 施例的实施步骤如下：
步骤101：主控锚点基站MeNB通过RRC消息RRC Connection Reconfiguration配置给UE按照本发明实施例的方式，进行高频目标TRP 1节点的Beams搜索，训练和跟踪和多个Beams的下行RRM测量。预定义Event NR-A1事件：UE对目标BF分流基站TRP所辖的全部所有或者多个Beams(>1)的算术平均导频信号强度RSRP或者质量RSRQ的测量结果(已经经过了层3过滤的处理)，和主控锚点基站通过RRC空口信令配置的门限值Thresh相比较，结果更好于一个神经缓冲偏移值Hys值，且持续超过一段事件触发时间TTT：time to trigger，这样UE触发本地产生NR-A1事件，并且MR上报给主控锚点基站。
步骤102：UE基于MeNB配置的RRM测量参数进行Beams跟踪同步和测量，通过TRP1所辖的4个Beams发射的下行公共同步信号，进行Beam训练跟踪，经过一段时间的同步训练之后，UE获得和最佳Beam1的下行“BF细同步子状态”；UE同时通过TRP1所辖Beams发射的下行公共导频信号，进行下行RRM测量，经过一段时间窗内的测量之后，UE获得已经同步上的最佳Beam1和TRP1所辖其他的Beam2/3/4的下行RRM测量结果。
步骤103：UE按照本发明实施例的新RRM评估模型，对能够跟踪同步上的服务Beam1/2/3/4的RRM初步测量采样值结果，经过层1过滤处理后而获得中间测量采样值，再经过层3过滤处理后而获得动态分析评估值，再对Beam1/2/3/4对应的动态分析评估值进行算术平均获得TRP1的整体综合评估值，在TTT观测窗内，如果TRP1的整体综合评估值>对比分析评估值Thresh+神经缓冲偏移值Hys值，则触发NR-A1事件。UE随后通过RRC消息Measurement Report上报给MeNB NR-A1事件，内容还可以包括：UE和最佳Beam1下行“BF细同步子状态”，TRP1所辖最佳的Beam1下行RRM测量结果。
步骤104：MeNB基于UE上报的结果，获悉UE已经和TRP1-Beam1实现下行“BF细同步子状态”，并且TRP1的整体综合质量满足预设的条件要求，决定为被服务UE和SeNB-TRP1建立高低频DC双连接操作，从 而按照类似LTE已有的双连接操作建立流程，在TRP1-Beam1上建立RL，进行上下行数据块的分流传输。
步骤105：SeNB通过X2接口，接收到MeNB发来的高低频DC双连接操作添加请求消息SeNB Addition Request，和目标RL建立相关的配置信息，SeNB能够判断TRP1也已经和被服务UE在Beam1实现了上行“BF细同步子状态”并且上行RRM测量结果良好，因此SeNB通过X2接口，反馈给MeNB消息SeNB Addition Request Ack，同意进行高低频DC双连接建立操作，并且同意在TRP1-Beam1上建立RL。
步骤106：MeNB通过RRC消息RRC Connection Reconfiguration配置给UE进行高低频紧耦合DC双连接操作，此后UE可以同时从MeNB-RL和SeNB-TRP1-RL两条无线链路上进行上下行的用户业务传输数据。
实施例2
如图9所示，主要是UE原本处于MeNB和TRP 1某源Beam的双连接数据传输状态，后来由于UE移动，被切换到MeNB和TRP 2某Beam的双连接数据传输状态。
下面对图9进行详细说明。
某运营商部署和利用了高低频紧耦合做双连接DC操作，在低频主控锚点基站MeNB所在的某授权载波上有Pcell的服务宏小区覆盖，在远端通过X2接口，连接SeNB高频分流基站TRP1和TRP2两个节点，SeNB节点所在某高频授权载波上有1个TRP1和1个TRP2，分别辖有4个服务Beams的部署，用于热点区域容量增强。
起始，UE已经处于Pcell和TRP1的联合覆盖之下，因此已经和MeNB和TRP1形成双连接操作。随着UE移动，UE逐渐离开TRP1-Beams的覆盖区域，而靠近Pcell+TRP2-Beams的公共覆盖区域，从而MeNB决定为UE配置相关的高频目标服务TRP2节点的测量参数，让UE对目标TRP2-Beams也同时进行下行RRM测量，默认地UE除了对源TRP1-Beams维持下行空间/时频跟踪同步之外，还需要先对目标TRP2-Beams进行下行空间/时频跟踪同步尝试。非BF低频MeNB节点和BF高频SeNB-TRP1/2节点和UE都 支持本发明实施例的内容能力。本发明实施例的实施步骤如下：
步骤201：主控锚点基站MeNB通过RRC消息RRC Connection Reconfiguration配置给UE按照本发明实施例的方式，进行高频目标TRP 1/2节点的Beams搜索，训练和跟踪和多个Beams的下行RRM测量。预定义Event NR-A2事件：UE对目标BF分流基站TRP所辖的全部所有或者多个Beams(>1)的平均导频信号强度RSRP或者质量RSRQ的测量结果(已经经过了层3过滤的处理)，和源BF分流基站TRP所辖的全部所有或者多个Beams(>1)的平均导频信号强度RSRP或者质量RSRQ的测量结果相比较，结果更好且大于一个被配置的神经缓冲偏移值Hys，且持续超过一段事件触发时间TTT：time to trigger，这样UE触发本地产生NR-A2事件，并且MR上报给主控锚点基站。
步骤202：UE基于MeNB配置的RRM测量参数进行Beams跟踪同步和测量，通过TRP2所辖的4个Beams发射的下行公共同步信号，进行Beam训练跟踪，经过一段时间的同步训练之后，UE获得和最佳TRP2-Beam2的下行“BF细同步子状态”；UE同时通过TRP2所辖Beams发射的下行公共导频信号，进行下行RRM测量，经过一段时间窗内的测量之后，UE获得已经同步上的最佳TRP2-Beam2和TRP2所辖其他的Beam1/3/4的下行RRM测量结果。
步骤203：UE按照本发明实施例的新RRM评估模型，对能够跟踪同步上的TRP1/2各自的服务Beam1/2/3/4的RRM初步测量采样值结果，经过各自层1过滤处理后而获得各自的中间测量采样值，再经过层3过滤处理后而获得各自的动态分析评估值，再对Beam1/2/3/4对应的动态分析评估值进行各自的算术平均获得TRP1和TRP2各自的整体综合评估值，在TTT观测窗内，如果TRP2的整体综合评估值>TRP1的整体综合评估值+神经缓冲偏移值Hys值，则触发NR-A2事件。UE随后通过RRC消息Measurement Report上报给MeNB NR-A2事件，内容还可以包括：UE和目标最佳TRP2-Beam2的下行“BF细同步子状态”，TRP2所辖最佳的Beam2下行RRM测量结果。
步骤204：MeNB基于UE上报的结果，获悉UE已经和目标 TRP2-Beam2实现下行“BF细同步子状态”，并且TRP2的整体综合质量满足预设的条件要求，决定为被服务UE和SeNB-TRP2建立高低频DC双连接操作，同时删除和源TRP1建立的旧RL，从而按照类似LTE已有的双连接操作修改流程，在TRP2-Beam2上建立新RL，继续进行上下行数据块的分流传输。
步骤205：SeNB通过X2接口，接收到MeNB发来的高低频DC双连接操作修改请求消息SeNB Modification Request，和目标新RL建立相关的配置信息，SeNB能够判断TRP2也已经和被服务UE在Beam2实现了上行“BF细同步子状态”并且上行RRM测量结果良好，因此SeNB通过X2接口，反馈给MeNB消息SeNB Modification Request Ack，同意进行高低频DC双连接修改操作，并且同意在TRP2-Beam2上建立新RL。
步骤206：MeNB通过RRC消息RRC Connection Reconfiguration配置给UE进行高低频紧耦合DC双连接操作，此后UE可以继续从MeNB-RL和SeNB-TRP2-RL两条无线链路上进行上下行的用户业务传输数据，原来的SeNB-TRP1-RL被删除，不能再进行数据分流传输贡献。
实施例3
如图10所示，UE原本处于NR(m)BS和TRP 1某源Beam的双连接数据传输状态，后来由于UE移动，被切换到NR(m)BS和TRP 2某Beam双连接数据传输状态。
下面对图10进行详细说明。
某运营商部署和利用了高低频紧耦合做双连接DC操作，在低频主控锚点基站NR(m)BS所在的某授权载波上有Pcell的服务宏小区覆盖，在远端通过Xnew接口，连接NR(s)BS高频分流基站TRP1和TRP2两个节点，NR(s)BS节点所在某高频授权载波上有1个TRP1和1个TRP2，分别辖有4个服务Beams的部署，用于热点区域容量增强。
起始，UE已经处于Pcell和TRP1的联合覆盖之下，因此已经和NR(m)BS和TRP1形成双连接操作。随着UE移动，UE逐渐离开TRP1-Beams的覆盖区域，而靠近Pcell+TRP2-Beams的公共覆盖区域，从而NR(m)BS 决定为UE配置相关的高频目标服务TRP2节点的测量参数，让UE对目标TRP2-Beams也同时进行下行RRM测量，默认地UE除了对源TRP1-Beams维持下行空间/时频跟踪同步之外，还需要先对目标TRP2-Beams进行下行空间/时频跟踪同步尝试。非BF低频NR(m)BS节点和BF高频NR(s)BS-TRP1/2节点和UE都支持本发明实施例的内容能力。本发明实施例的实施步骤如下：
步骤301：主控锚点基站NR(m)BS通过RRC消息RRC Connection Reconfiguration配置给UE按照本发明实施例的方式，进行高频目标TRP1/2节点的Beams搜索，训练和跟踪和多个Beams的下行RRM测量。预定义Event NR-A3事件：UE对目标BF分流基站TRP所辖的全部所有或者多个Beams(>1)的平均导频信号强度RSRP或者质量RSRQ的测量结果(已经经过了层3过滤的处理)比某个配置门限Thresh1更好，且大于被配置的神经缓冲偏移值Hys1，同时源BF分流基站TRP所辖的全部所有或者多个Beams(>1)的平均导频信号强度RSRP或者质量RSRQ的测量结果比另外某个配置门限Thresh2更差，且大于被配置的神经缓冲偏移值Hys2，且都各自持续超过一段事件触发时间TTT：time to trigger，这样UE触发本地产生NR-A3事件，并且MR上报给主控锚点基站。
步骤302：UE基于NR(m)BS配置的RRM测量参数进行Beams跟踪同步和测量，通过TRP1/2各自所辖的4个Beams发射的下行公共同步信号，进行Beam训练跟踪，经过一段时间的同步训练之后，UE获得和最佳TRP2-Beam3的下行“BF细同步子状态”；UE同时通过TRP1/2各自所辖Beams发射的下行公共导频信号，进行下行RRM测量，经过一段时间窗内的测量之后，UE获得已经同步上的最佳TRP2-Beam3和TRP2所辖其他的Beam1/2/4的下行RRM测量结果。
步骤303：UE按照本发明实施例的新RRM评估模型，对能够跟踪同步上的TRP1/2各自的服务Beam1/2/3/4的RRM初步测量采样值结果，经过各自层1过滤处理后而获得各自的中间测量采样值，再经过层3过滤处理后而获得各自的动态分析评估值，再对Beam1/2/3/4对应的动态分析评估值进行各自的加权平均(不同Beam不同的权重)获得TRP1和TRP2各自的整体 综合评估值，在TTT观测窗内，如果TRP2的整体综合评估值>门限Thresh1+神经缓冲偏移值Hys1值，同时TRP1的整体综合评估值<门限Thresh2-神经缓冲偏移值Hys2值，则触发NR-A3事件。UE随后通过RRC消息Measurement Report上报给NR(m)BS NR-A3事件，内容还可以包括：UE和目标最佳TRP2-Beam3的下行“BF细同步子状态”，TRP2所辖最佳的Beam3下行RRM测量结果。
步骤304：NR(m)BS基于UE上报的结果，获悉UE已经和目标TRP2-Beam3实现下行“BF细同步子状态”，并且TRP1/2各自的整体综合质量满足预设的条件要求，决定为被服务UE和NR(s)BS-TRP2建立高低频DC双连接操作，同时删除和源TRP1建立的旧RL，从而按照NR双连接操作修改流程，在TRP2-Beam3上建立新RL，继续进行上下行数据块的分流传输。
步骤305：NR(s)BS通过Xnew接口，接收到NR(m)BS发来的高低频DC双连接操作修改请求消息NR BS Modification Request，和目标新RL建立相关的配置信息，NR(s)BS能够判断TRP2也已经和被服务UE在Beam3实现了上行“BF细同步子状态”并且上行RRM测量结果良好，因此NR(s)BS通过Xnew接口，反馈给NR(m)BS消息NR BS Modification Request Ack，同意进行高低频DC双连接修改操作，并且同意在TRP2-Beam3上建立新RL。
步骤306：NR(m)BS通过RRC消息RRC Connection Reconfiguration配置给UE进行高低频紧耦合DC双连接操作，此后UE可以继续从NR(m)BS-RL和NR(s)BS-TRP2-RL两条无线链路上进行上下行的用户业务传输数据，原来的NR(s)BS-TRP1-RL被删除，不能再进行数据分流传输贡献。
通过以上的实施方式的描述，本领域的技术人员可以清楚地了解到根据上述实施例的方法可借助软件加必需的通用硬件平台的方式来实现，当然也可以通过硬件，但很多情况下前者是更佳的实施方式。基于这样的理解，本发明实施例可以以软件产品的形式体现出来，该计算机软件产品存储在一个存储介质(如ROM/RAM、磁碟、光盘)中，包括若干指令用以使得一台终端设备(可以是手机，计算机，服务器，或者网络设备等)执行本 发明各个实施例所述的方法。
实施例2
在本实施例中还提供了一种无线链路管理装置，该装置用于实现上述实施例及实施方式，已经进行过说明的不再赘述。如以下所使用的，术语“模块”可以实现预定功能的软件和/或硬件的组合。尽管以下实施例所描述的装置可以以软件来实现，但是硬件，或者软件和硬件的组合的实现也是可能并被构想的。

3)第一管理模块116，设置为基于多个或者全部波束联合评估该RRM测量结果，并根据评估结果从源BF分流基站TRP切换至目标BF分流基站TRP或者额外添加目标BF分流基站TRP。
在本实施例中，上述无线链路管理装置的应用场景包括但并不限于：波束成形基站间无线资源控制(Radio Resource Management简称为RRM)测量评估切换。在该应用场景下，终端UE接收基站通过无线资源控制RRC信令下发的无线资源管理RRM测量参数；根据该RRM测量参数，对目标波束成形BF分流基站发送接收点TRP所辖的多个或者全部波束进行RRM测量，获得RRM测量结果；基于多个或者全部波束联合评估该RRM测量结果，并根据评估结果从源BF分流基站TRP切换至目标BF分流基站TRP或者额外添加目标BF分流基站TRP。也就是说，在本实施例中，以每一TRP所辖的多个或者全部波束作为RRM测量粒度，因此，可以避免以单个波束为粒度进行无线资源控制测量评估并进行波束成形基站间移动切换所导致终端移动性能较差的情况，达到提高终端移动性能的效果。
