Description

一种测量方法和测量装置

技术领域
本申请涉及通信领域，并且更具体地，涉及一种测量方法和测量装置。
背景技术
移动通信系统需要满足用户的移动体验，实现终端设备移动时的业务连续性，终端设备不仅要和服务小区保持稳定的通信联系，还需要实时检测邻区的状态。连接态移动性管理包括邻区的测量配置，测量执行，测量上报，事件触发和/或切换判决等。如何在合适的小区进行测量，测量的精度和测量周期等都对最终移动性管理的性能有很大影响。
在新空口(new radio，NR)技术中，终端设备在进入连接态以后，网络设备会向终端设备发送邻区测量配置信息，邻区测量配置信息中仅下发绝对频点编号(absolute radio frequency channel number，ARFCN)，由终端设备确定ARFCN与频段(band)号的对应以及频段的选择，终端设备通过随机选择ARFCN对应的某一个频段进行测量并进行测量上报。若网络设备确定对终端设备进行切换，则网络设备会在切换(handover，HO)信令中，给终端设备下发唯一的频段指示，这个频段是由网络设备的实现算法决定的。
由于NR中一个ARFCN可能对应多个频段，终端设备在不同频段对应的射频链路(radio frequency，RF)进行测量的测量值不同，有可能导致终端设备的测量精度不准确，并且进一步导致终端设备的错误切换或者切换失败。

应理解，本申请提供的通信方法可适用于无线通信系统，例如，图1中所示的无线通信系统100。处于无线通信系统中的两个通信装置间具有无线通信连接，该两个通信装置中的一个通信装置可对应于图1中所示的终端设备130，例如，可以为图1中的终端设备130，也可以为配置于终端设备130中的芯片；该两个通信装置中的另一个通信装置可对应于图1中所示的RAN110，例如，可以为图1中的RAN110，也可以为配置于RAN110中的芯片。
以下，不失一般性，以终端设备与网络设备之间的交互过程为例详细说明本申请实施例。可以理解，处于无线通信系统中的任意一个终端设备可以基于相同的方法与具有无线通信连接的一个或多个网络设备通信。本申请对此不做限定。
图2是本申请实施例提供的一种网络架构的示意图，如图2所示，该网络架构包括CN设备和RAN设备。其中RAN设备包括基带装置和射频装置，其中基带装置可以由一个节点实现，也可以由多个节点实现，射频装置可以从基带装置拉远独立实现，也可以集成基带装置中，或者部分拉远部分集成在基带装置中。例如，在LTE通信系统中，RAN设备(eNB)包括基带装置和射频装置，其中射频装置可以相对于基带装置拉远布置，例如射频拉远单元(remote radio unit，RRU)相对于BBU拉远布置。
RAN设备和终端设备之间的通信遵循一定的协议层结构。例如控制面协议层结构可以包括无线资源控制(radio resource control，RRC)层、分组数据汇聚层协议(packet data convergence protocol，PDCP)层、无线链路控制(radio link control，RLC)层、媒体接入 控制(media access control，MAC)层和物理层等协议层的功能。用户面协议层结构可以包括PDCP层、RLC层、MAC层和物理层等协议层的功能；在一种实现中，PDCP层之上还可以包括业务数据适配(service data adaptation protocol,SDAP)层。
这些协议层的功能可以由一个节点实现，或者可以由多个节点实现；例如，在一种演进结构中，RAN设备可以包括集中单元(centralized unit，CU)和分布单元(distributed unit，DU)，多个DU可以由一个CU集中控制。如图2所示，CU和DU可以根据无线网络的协议层划分，例如PDCP层及以上协议层的功能设置在CU，PDCP以下的协议层，例如RLC层和MAC层等的功能设置在DU。
RAN设备可以由一个节点实现无线资源控制(radio resource control，RRC)、分组数据汇聚层协议(packet data convergence protocol，PDCP)、无线链路控制(radio link control，RLC)、和媒体接入控制(Media Access Control，MAC)等协议层的功能；或者可以由多个节点实现这些协议层的功能；例如，在一种演进结构中，RAN设备可以包括集中单元(centralized unit，CU)和分布单元(distributed unit，DU)，多个DU可以由一个CU集中控制。如图2所示，CU和DU可以根据无线网络的协议层划分，例如PDCP层及以上协议层的功能设置在CU，PDCP以下的协议层，例如RLC层和MAC层等的功能设置在DU。
这种协议层的划分仅仅是一种举例，还可以在其它协议层划分，例如在RLC层划分，将RLC层及以上协议层的功能设置在CU，RLC层以下协议层的功能设置在DU；或者，在某个协议层中划分，例如将RLC层的部分功能和RLC层以上的协议层的功能设置在CU，将RLC层的剩余功能和RLC层以下的协议层的功能设置在DU。此外，也可以按其它方式划分，例如按时延划分，将处理时间需要满足时延要求的功能设置在DU，不需要满足该时延要求的功能设置在CU。
此外，射频装置可以拉远，不放在DU中，也可以集成在DU中，或者部分拉远部分集成在DU中，在此不作任何限制。
请继续参考图3，图3示出了本申请实施例提供的另一种网络架构的示意图，相对于图2所示的架构，还可以将CU的控制面(CP)和用户面(UP)分离，分成不同实体来实现，分别为控制面CU实体(CU-CP实体)和用户面CU实体(CU-UP实体)。
在以上网络架构中，CU产生的信令可以通过DU发送给终端设备，或者终端设备产生的信令可以通过DU发送给CU。DU可以不对该信令进行解析而直接通过协议层封装而透传给终端设备或CU。以下实施例中如果涉及这种信令在DU和终端设备之间的传输，此时，DU对信令的发送或接收包括这种场景。例如，RRC或PDCP层的信令最终会处理为PHY层的信令发送给终端设备，或者，由接收到的PHY层的信令转变而来。在这种架构下，该RRC或PDCP层的信令，即也可以认为是由DU发送的，或者，由DU和射频发送的。
在以上实施例中CU划分为RAN侧的网络设备，此外，也可以将CU划分为CN侧的网络设备，在此不做限制。
本申请以下实施例中，当采用以上CU-DU的结构时，网络设备可以为CU节点、或DU节点、或包括CU节点和DU节点的RAN设备。
下面，在介绍本申请实施例之前，首先对本申请实施例涉及的技术术语进行简单介绍。
1、绝对频点编号(ARFCN)
LTE中的绝对频点编号(E-UTRAN absolute radio frequency channel number，EARFCN)为每一个码号指示一个LTE载波的频点位置，由于在EARFCN的计算方法中参考起点为每一个频段的起始点，EARFCN在不同频段(Band)相同频点上的编号不同。
例如，LTE Band38的频段范围是2570-2620MHz，LTE Band41的频段范围是2496-2690MHz。这两个Band在2570M-2620MHz上实际是重叠的。以2570MHz为例，在Band38上，该频点对应的EARFCN号为37750，在Band41上，该频点对应的EARFCN号为40390。
NR中的绝对频点编号(NR absolute radio frequency channel number，NR-ARFCN)与LTE中的类似，但在NR-ARFCN计算方法中参考起点为公共频点，使得NR-ARFCN在不同Band相同频点上的编号是相同的，即每一个NR-ARFCN对应一个唯一的绝对频点。
2、同步信号广播信道块(synchronous signal/PBCH block，SS/PBCH block)
LTE中，主同步信号(primary synchronization signal，PSS)与从同步信号(secondary synchronization signal)(PSS和SSS)和物理广播信道(physical broadcast channel，PBCH)块的频域位置与NR中不同，PSS和SSS信号位于载波频点位置，因此LTE的测量配置信息下发的是载波频点的位置。
SS/PBCH block还可以称为SSB，SSB为NR中无线资源管理(radio resource management，RRM)测量中的一种参考信号，包含同步信号/物理广播信道，一个SSB由主同步信号、从同步信号，物理广播信道(physical broadcast channel，PBCH)以及为了解调PBCH所需的解调参考信号(demodulation reference signal，DMRS)构成。其中，PSS主要用于粗同步，SSS用于精同步以及基于SSB的测量，PBCH用于广播小区级别的系统信息，而DMRS除了用于PBCH的解调外，也可以用于基于SSB的测量。
3、信道状态信息参考信号(channel state information reference，CSI-RS)
CSI-RS为NR中无线资源管理(radio resource management，RRM)测量中的另一种参考信号。
4、频段列表(frequency band list)
LTE中在空闲态的系统消息中下发frequencyBandInfo和扩展频段指示(multiple frequency band indicator，MFBI)，使得仅支持网络设备扩展频段(Band)的终端设备也能够驻留网络设备。LTE的测量配置信息中下发载波频点位置，该信息与Band有天然的对应关系。LTE的切换信令中下发目标小区的Band信息，使得终端设备唯一确定切换目标。
NR中在空闲态的系统消息中、连接态切换命令或小区激活信令都可能会下发的当前服务小区或邻区频段列表。但系统消息以及空闲态中下发的内容和连接态中下发的内容有所不同，系统消息以及空闲态中下发的多个频段的信息，包括了网络设备当前载波所属的多个频段的信息；而在切换(HO)或其他连接态信令中下发的唯一频段的信息。
5、RF通道参数
目前在NR中，移动通信系统在全球各国家和地区的工作频谱离散，LTE的协议定义了几十种工作频段，NR中也定义数几十种工作频段。很多工作频段存在部分频谱重叠的情况，终端设备的RF设计对交叠频谱处的不同Band可能会使用不同的RF通道支持，不 同通道上的RF前端器件堆叠和选型都可能不同，造成相同频点不同Band处的RF通道上的前端器件的插损(insertion loss)不同。前端器件的插损不同直接造成不同RF通道上的噪声系数不同，即噪声被电路的热噪声抬高。
终端设备的每个Band与射频通道的对应关系，以及相应的RF通道参数可以存储在终端设备的NV(nonvolatile)文件中，终端设备开机时会把该文件的内容加载到终端设备的存储器中，终端设备需要使用这些参数的时候，可以在存储器中获得。
现有技术中，终端设备的连接态邻区测量配置信息中包括了一个绝对频点编号，该终端设备在收到该绝对频点编号后，该绝对频点编号可以对应多个频段，例如，一个绝对频点编号对应了两个频段(Band A和Band B)，而该终端设备可能同时支持Band A和Band B并且可以通过该终端设备的能力上报，此时终端设备存在选择RF通道的问题，目前NR协议中仅下发绝对频点编号的方式，假设多个交叠频段用一个RF通道支持，或者多个交叠频段用多个RF通道支持但该多个RF通道的RF指示性能一致的基础上才成立，但是这两个假设在实际终端设备实现中可能都不会成立。
本申请实施例中通过在测量配置信息中增加测量对象的频段信息(例如，frequency band list)，其中该频段信息可以是多个频段的信息，也可以是一个频段的信息，终端设备可以根据测量配置中增加的频段信息进行测量，有助于保证整个测量过程和最终的切换过程决策具备一致性。
图4示出了本申请实施例提供的测量方法200的示意性流程图，如图4所示，该方法200包括：
S210，网络设备确定一个或者多个频段。
具体而言，该一个或者多个频段用于终端设备的测量，终端设备可以从该一个或者多个频段中选择出一个频段进行测量。
S220，该网络设备向终端设备发送测量配置信息，该终端设备接收该网络设备发送的该测量配置信息，该测量配置信息至少包括测量对象的绝对频点编号和该一个或者多个频段的信息。
可选地，该网络设备向该终端设备发送RRC重配(RRCReconfiguration)信令，该信令中的测量配置信令(measConfig)包括该测量对象(measurement object)信息。
具体而言，该网络设备在确定该一个或者多个频段后，向该终端设备发送测量配置信息，相比于现有技术，该网络设备可以在该测量配置信息中的测量对象信息增加字段来指示该一个或者多个频段。
应理解，本申请实施例中，该测量配置信息至少包括测量对象的绝对频点编号和一个或者多个频段的信息还可以理解为该测量配置信息至少包括测量对象的绝对频点编号和该一个或者多个频段的映射关系。
可选地，该映射关系可以以表格的形式体现，该映射关系可以是绝对频点编号和一个频段的映射关系，如表1所示，表1示出了一种绝对频点编号和一个频段的映射关系。
表1绝对频点编号和一个频段的映射关系

可选地，该映射关系也可以是绝对频点编号和多个频段的映射关系，如表2所示，表2示出了一种绝对频点编号和多个频段的映射关系。
表2绝对频点编号和一个频段的映射关系
Figure PCTCN2019093119-appb-000001
应理解，Band A和Band B包括绝对频点编号X所对应的频点。
还应理解，表2仅仅是示意性的，测量配置信息中可以包括绝对频点编号X对应的两个频段(Band B和Band C)的信息，还可以包括绝对频点编号X对应的三个或者三个以上的频段的信息。
还应理解，在绝对频点编号的计算中，绝对频点编号X可以对应三个频段(Band A、Band B和Band C)，但是网络设备在测量配置中携带的一个或者多个频段的信息可以为Band B和Band C的信息。
可选地，该测量配置信息还包括上报配置(reporting configuration)、测量配置(quantity configuration)和测量间隔配置等。
可选地，该测量对象信息还包括字段，该字段用于指示该一个或者多个频段。
具体而言，本申请实施例中的测量对象可以是SSB和CSI-RS，该网络设备可以在测量配置信息中的测量对象信息中增加字段指示该SSB对应的一个或者多个频段的信息和该CSI-RS所对应的该一个或者多个频段的信息。
应理解，该SSB对应的一个或者多个频段可以和CSI-RS对应的一个或者多个频段不同。
可选地，该一个或者多个频段的信息可以为frequency band list。
本申请实施例的测量方法，通过网络设备在测量配置信息中下发唯一频段的信息，有助于在保证测量精度的同时，避免终端设备的错误切换或者切换失败。
在一些可能的实现方式中，若该网络设备确定的该一个或者多个频段不包括该网络设备的主支持频段，也不包括该网络设备的扩展支持频段，则该网络设备可以不向终端设备发送测量配置信息。
S230，该终端设备确定第一频段对应的射频链路通道配置参数，该第一频段为该一个或者多个频段，或者，该第一频段为多个频段中的一个频段。
应理解，本申请实施例中，射频链路通道配置参数实际对应RF通道的选择，RF通道的配置主要包括RF通道的编号以及不同的自动增益控制(automatic gain control，AGC)的补偿系数。
具体而言，该网络设备向该终端设备发送该测量配置信息后，该终端设备获得该一个或者多个频段的信息，若该第一频段为多个频段中的一个频段，则该终端设备从该多个频段中选择第一频段，并确定该第一频段对应的射频链路通道配置参数；或者，若该第一频段为该一个或者多个频段，则该终端设备确定该第一频段对应的射频链路通道配置参数。
例如，该第一频段为该多个频段中的一个频段(例如，该多个频段包括Band B和Band C)，则该终端设备可以先从这两个频段中选择一个频段(例如，Band B)，随后确定Band B对应的RF通道配置参数。
又例如，该第一频段为该一个或者多个频段(例如，Band A，其中，Band A可以由一个频段构成，或者也可以由多个频段构成)，则该终端设备可以直接确定Band A对应的RF通道配置参数。
可选地，该第一频段为该多个频段中的一个频段时，该终端设备确定第一频段对应的射频链路通道配置参数之前，该方法还包括：
该终端设备从该多个频段中确定该第一频段。
可选地，该终端设备根据自身硬件能力从该多个频段中选择该第一频段。
可选地，该终端设备从该多个频段中确定该第一频段，包括：
该终端设备将该多个频段中与服务小区相同的频段确定为该第一频段；或者，
该终端设备将该多个射频链路通道上噪声系数性能最好的射频链路通道对应的频段确定为该第一频段，其中，该多个频段对应该多个射频链路通道。
应理解，本申请实施例中，UE的射频链路(RF)设计对交叠频谱处的不同频段可能会使用不同的RF通道支持，不同通道上的RF前端器件堆叠和选型都可能不同，造成相同频点不同频段处的RF通道上的前端插损不同。插损不同直接表现为不同RF通道上的噪声系数不同，即噪声被电路的热噪声抬高。RF通道上的噪声系数的不同会导致终端设备对测量对象测得测量结果不同，使得不同频段对应的RF通道得到的精度不同。
可选地，该第一频段为该网络设备的主频段，或者，该第一频段为该网络设备的扩展支持频段中的一个频段。
S240，该终端设备根据该射频链路通道配置参数，对测量对象进行测量；
S250，该终端设备向该网络设备发送该测量对象的测量结果，该网络设备接收该终端设备发送该测量结果。
可选地，该测量对象可以包括SSB和/或CSI-RS。
可选地，该测量结果包括该测量对象的信号与干扰加噪比(signal to interference plus noise ratio，SINR)、参考信号接收功率(reference signal receiving power，RSRP)或参考信号接收质量(reference signal receiving quality)或接收信号强度指示(received signal strength indicator,RSSI)中的一种或者多种。
具体而言，该终端设备确定该第一频段对应的射频链路通道配置参数后，在该第一频段对应的RF通道上接收测量对象(SSB和/或CSI-RS)，该终端设备在该测量对象的绝对频点编号对应的频点上接收SSB和/或CSI-RS。
物理层测量类型包括:RSSI，SS-RSRP，CSI-RSRP，SS-RSRQ，CSI-RSRQ，SS-SINR和/或CSI-SINR，这些测量类型都可以用于连接态下的同频/异频测量.
SS-RSRP的测量定义在从同步参考信号(SSS)上的资源元素(resource element，RE)的功率的线性平均值，参考点位于UE的天线连接口处。
CSI-RSRP的测量定义在CSI-RS信号的RE的功率的线性平均值，可用测量带宽由信令指示。测量参考点位于UE的天线连接口处。
SS-RSRQ的定义为N×SS-RSRP/NR carrier RSSI，其中SS-RSRP表示SS上的RE的功率的线性平均值，RSSI为NR载波接收信号强度指示，即测量时间资源内的测量带宽上的总接收功率的线性平均，总接收功率包括各种来源的功率，如服务小区，非服务小区，邻信道干扰，热噪声等等，CSI-RSRQ的定义类似。
SS-SINR的测量定义为SSS的RE的接收功率的线性平均与噪声和干扰的功率的比值，CSI-SINR的定义类似。
参考信号的测量是在信令指示或协议中规定的相应时频资源上对相应信号的接收和功率计算。其中RSRP为参考信号在天线口位置处的功率绝对值，该测量值能够通过对相应RF通道上的前端器件热噪声的功率补偿，使得RSRP信号在相同频点不同频段的上测量结果一致。测量值RSRQ和SINR为包括噪声功率在内的功率值测量，即反应了信号与噪声的比值，前端器件噪声的不一致会导致该类测量值的精确度受到影响。
应理解，本申请实施例中，该接收测量对象的过程即为测量该测量对象的过程。
还应理解，本申请实施例中，并不对接收信号的类型进行限定，可以是SSB和/或CSI-RS，还可以是其他信号。
可选地，该方法还包括：
该网络设备根据该测量结果，确定是否对该终端设备进行切换。
具体而言，该终端设备在上报测量结果后，该网络设备可以根据该测量结果确定对该终端设备是否执行切换。
应理解，本申请实施例中，终端设备对相应测量对象进行测量执行后，测量结果如果对应到某一事件中则会进入上报触发，并将测量值通过测量报告发送给网络设备，网络设备通过切换命令通知终端设备进行切换，相应上报触发事件的定义如下：
●事件A1(服务小区触发量高于阈值)：用于停止异频测量。
●事件A2(服务小区触发量低于阈值)：用于启动异频测量。
●事件A3(邻区触发量考虑偏移值后好于服务小区的触发量)：启动同频/异频切换请求。
●事件A4(邻区触发量高于阈值)：启动异频切换请求。
●事件A5(服务小区的触发量低于阈值1，邻区的触发量高于阈值2)：启动异频切换请求。
●事件A6(邻区的触发量考虑偏差后好于辅小区(Scell)的触发量)：启动同频/异频切换请求。
还应理解，本申请实施例中根据该第一频段对应的RF通道配置参数测量该测量对象，所得到的测量结果为邻区的测量结果，例如，若该测量结果高于阈值，则向网络设备上报该测量结果，该网络设备根据该测量结果，通过切换命令通知终端设备进行切换，该切换命令中包括该第一频段的信息。

图5示出了本申请实施例的测量方法300，如图5所示，该测量方法300包括：
S310，终端设备向网络设备发送该终端设备支持的频段的信息，该网络设备接收该终端设备支持的频段的信息。
具体而言，该终端设备可以在能力上报的信令中携带该终端设备支持的频段的信息。

例如，该测量配置信息中包括的绝对频点编号对应第一频段和第二频段，该终端设备分别确定第一频段和第二频段的RF通道配置参数(第一频段对应第一配置参数，第二频段对应第二配置参数)，该终端设备分别使用该第一配置参数和该第二配置参数，对该测量对象进行测量，得到第一测量结果(针对第一频段的测量结果)以及第二测量结果(针对第二频段的测量结果)，该第一测量结果中包括该第一频段的信息，该第二测量结果中包括该第二频段的信息。
