网络设备2是能和终端1进行通信的设备，可以是基站、中继站或接入点。基站可以是全球移动通信系统(global aystem for mobile communication，GSM)或码分多址(code division multiple access，CDMA)网络中的基站收发信台(base transceiver station，BTS)，也可以是宽带码分多址(wideband code division multiple access，WCDMA)中的节点基站(nodebase station，NB)，还可以是长期演进(long term evolution，LTE)中的演进型(evolutional)NB(eNB或eNodeB)，还可以是云无线接入网络(cloud radio access network，CRAN)场景下的无线控制器，还可以是未来5G网络中的基站设备或者未来演进的PLMN网络中的网络设备，还可以是可穿戴设备或车载设备。
为了更好地理解本发明实施例公开的一种通信方法及设备，下面先对本发明实施例中用到的概念或术语进行定义。
QCL：共址关系用于表示多个资源之间具有一个或多个相同或者相类似的通信特征，对于具有共址关系的多个资源，可以采用相同或者类似的通信配置。例如，如果两个天线端口具有共址关系，那么一个端口传送一个符号的信道大尺度特性可以从另一个端口传送一个符号的信道大尺度特性推断出来。大尺度特性可以包括延迟扩展、平均延迟、多普勒扩展、多普勒频移、平均增益、接收参数、终端接收波束编号、发射/接收信道相关性、接收到达角(angel-of-arrival，AOA)、接收机天线的空间相关性、主AOA、平均AOA、AOA的扩展等。具体地，共址指示用于指示至少两组天线端口是否具有共址关系为：共址指示用于指示至少两组天线端口发送的SCI-RS是否来自相同的传输点或波束组。网络设备可以通知终端发送RS的端口具有QCL关系，帮助终端进行RS的接收和解调。例如，终端能确认A端口和B端口具有QCL关系，即可以将A端口上测得的RS的大尺度参数用于B端口上的RS的测量和解调。空域(spatial)QCL为QCL的一种，空域可以从发送端或接收端来理解。从发送端来看，如果两个天线端口是空域QCL，则这两个天线端口对应的波束方向在空间上一致。从接收端来看，如果两个天线端口是空域QCL，则接收端能够在相同的波束方向上接收到这两个天线端口发送的信号。
无线通信的信号需要由天线进行接收和发送，多个天线单元(antenna element)可以集成在一个面板上(panel)组成天线面板。一个射频(radio frequency，RF)链路可以驱动一个或多个天线单元。终端和网络设备均可以包括一个或多个天线面板，每个天线面板可以 包括一个或者多个波束。天线面板可以表示为天线阵列(antenna array)或天线子阵列(antenna subarray)。一个天线面板可以包括一个或多个天线阵列/子阵列。一个天线面板可以由一个或多个晶振(oscillator)控制。RF链路可以称为接收通道和/或发送通道，接收机支路(receiver branch)等。一个天线面板可以由一个RF链路驱动，也可以由多个RF链路驱动。
波束：是一种通信资源，可以是宽波束，也可以是窄波束，还可以是其他类型波束。形成波束的技术可以是波束成形技术，也可以是其他技术手段。波束成形技术可以为数字波束成形技术、模拟波束成形技术或混合数字模拟波束成形技术。不同的波束可以认为是不同的资源。终端和网络设备可以通过不同的波束发送相同的信息或者不同的信息。可以将具有相同或者类似通信特征的多个波束视为一个波束。一个波束内可以包括一个或多个天线端口，用于传输数据信道、控制信道和探测信号等，例如，发射波束可以是指信号经天线发射出去后在空间不同方向上形成的信号强度的分布，接收波束可以是指从天线上接收到的无线信号在空间不同方向上的信号强度分布。形成一个波束的一个或多个天线端口可以看作一个天线端口集。波束在协议中的体现还可以是空域滤波器(spatial filter)。波束的信息可以通过索引信息进行标识。索引信息可以对应配置终端的资源标识，比如，索引信息可以对应配置的CSI-RS的标识(identity，ID)或者资源，也可以对应配置的上行SRS的ID或者资源。索引信息还可以是通过波束承载的信号或信道显示或隐式承载的索引信息，比如，索引信息可以是通过波束发送的同步信号(synchronization signal，SS)或者PBCH指示该波束的索引信息。波束的信息的标识可以包括通过波束的绝对索引、波束的相对索引、波束的逻辑索引、波束对应的天线端口的索引、波束对应的天线端口组的索引、下行SS块的时间索引、波束对应的连接(beam pair link，BPL)信息或索引、波束对应的发送参数(Tx parameter)或索引、波束对应的接收参数(Rx parameter)或索引、波束对应的发送权重(weight)或索引、权重矩阵(weight vector)、权重向量(weight matrix)、波束对应的接收权重、波束对应的发送码本(codebook)或索引、波束对应的接收码本或索引等。
波束管理资源：为用于波束管理的资源，又可以体现为用于计算和测量波束质量的资源。波束质量可以包括层一(layer 1，L1)-接收参考信号功率(reference signal received power，RSRP)、L1-接收参考信号质量(reference signal received quality，RSRQ)等。波束管理资源可以包括SS、PBCH、下行信道测量参考信号(reference signal，RS)、跟踪信号、PDCCH DMRS、PDSCH DMRS、上行信道SRS、上行随机接入信号等。采用RSRP、块误码率(block error rate，BLER)、RSRQ、RS接收强度指示(received signal strength indicator，RSSI)、信噪比(signal to interference and noise ratio，SINR)、信号质量指示(channel quality indicator，CQI)、相关性等指标度量波束质量。
在NR中，网络设备使用TCI状态(state)通知终端接收RS时接收波束之间的关联关系，例如，接收CSI-RS或同步信号块(synchronization signal block，SSB)和接收PDSCH的DMRS的波束之间的关系。网络设备可以通过无线资源控制(radio resource control，RRC)高层信令配置了一个TCI状态表(对应38.331中的TCI-states)，每个TCI状态表包含若干个TCI状态(对应38.331中的TCI-RS-集合(Set))。每个TCI状态包括TCI状态ID(对应38.331中的TCI-RS-SetID)、一种或两种QCL类型指示(对应38.331中的QCL-类型(type)A/B/C/D)以及 各个类型指示对应的RS-ID。QCL类型包含了以下几种：
QCL-Type A:{多普勒频移,多普勒扩展,平均时延,时延扩展}
QCL-Type B:{多普勒频移,多普勒扩展}
QCL-Type C:{平均时延,多普勒频移}
QCL-Type D:{空间接收参数}
其中，QCL-type D表示空间QCL。当需要指示接收波束时，网络设备可以通过高层信令或控制信息(如PDCCH)指示其中的一个包含空间QCL信息的TCI状态，终端可以根据该TCI状态读取QCL-type D对应的RS-ID，然后终端可以根据当前维护的与RS-ID相对应的空间接收配置(接收波束)进行接收。如果一个TCI状态中含有空间QCL指示(QCL-type D)，那么该空间QCL指示的对应RS可能是一个SSB/PBCH块(block)或是一个周期或半持续的CSI-RS。
不同下行信道的波束指示(TCI指示)可以在不同位置，PDCCH的波束指示由RRC配置的高层信令tci-StatesPDCCH与一个或多个TCI状态关联，当关联的TCI状态数大于1时，由媒体接入控制(media access control，MAC)控制信令(control element，CE)高层信令选择其中一个。PDSCH的波束指示由PDCCH传输的下行控制信息(downlink control information，DCI)中的TCI字段关联的状态进行指示。NR标准中DCI中包含的TCI字段的长度为3bit(对应8个TCI状态)，当RRC信令包含的TCI状态数量小于8时，激活的TCI状态直接映射到TCI字段中，否则由高层信令指示最多8种参与映射的TCI状态。当高层信令提示TCI字段未在DCI中出现时，终端重用控制信道的波束指示进行数据信道接收。
对于上行传输，NR尚未定义空间QCL关系，上行的波束指示直接通过RS资源标识实现。PUCCH的波束指示通过RRC参数PUCCH-Spatial-relation-info指示，RRC参数可以包括一个或者多个RS资源标识，当包含多个RS资源标识时，由MAC CE选择其中一个。PUCCH的波束指示内容可以是上行或下行的RS资源标识，包括SSB索引(index)、CSI-RS指示(CSI-RS Resource Indicator,CRI)或SRS索引，可以建议终端使用接收/发送该下行/上行RS资源的对应波束进行上行传输。PUSCH的波束信息通过DCI中的SRS索引进行配置。
为了更好地理解本发明实施例公开的一种通信方法及设备，下面先对本发明实施例的应用场景进行描述。在第三代合作伙伴计划(3rd generation partnership project，3GPP)协议的第15版本(release 15)中，在基站发送波束扫描过程中，终端需要从基站的发送波束中选择1-4个波束进行RSRP上报；在终端接收波束扫描过程中，基站会只用一个固定发送波束发送多个RS资源，终端利用这些RS资源训练自己的接收波束，终端不需要对选择的接收波束和接收波束对应的发送波束进行上报。
从上述基站发送波束扫描和终端接收波束扫描过程中可以确定终端侧接收波束的选择完全由终端来实现，但是，当终端采用基于波束进行定位测量时，由于不同的接收波束测量的结果会差异很大，如果终端仅上报测量结果而不指明具体的波束，会导致网络侧在使用终端的上报结果进行定位计算的时候导致计算误差较大，从而使得定位测量误差较大。为了提高定位精度，终端上的AOD等一些信息的确定需要终端接收波束使用同一个接收波束对一组发送波束进行接收并测量相关参数，并将测量结果进行上报，从而使得网络设备 可以通过终端的测量结果来计算终端的位置。
基于图1所示的网络架构，请参阅图2，图2是本发明实施例公开的另一种通信方法的流程示意图。如图2，该通信方法可以包括如下步骤。
201、网络设备向终端发送测量指示。
网络设备需要终端进行测量的情况下，需要向终端发送测量指示，以便终端根据测量指示对RS开始测量。
具体地，测量指示可以通过PDCCH进行指示，也可以通过高层信令进行指示，高层信令可以是MAC CE或者RRC信令。如果通过高层信令进行测量指示时，应考虑终端收到测量指示到接收RS之间的时间差。如果网络设备通过专用配置的用于定位测量的RS，则需要保证终端在接收到高层配置信令后进行RS的接收。
如果是通过PDCCH进行指示，则RS的发送和PDCCH可以在同一个时隙或子帧。
具体采用哪种配置方式本申请不做限定。
202、网络设备向终端发送用于定位测量的RS。
网络设备需要终端进行定位测量，或者终端需要进行定位测量时，网络设备可以为终端配置用于定位测量的RS，并向终端发送配置的RS。其中，定位测量可以是角度测量、到达时间测量、信号质量测量、到达角度测量、到达时间差测量、到达角度差测量等中的一个或多个。信号质量测量可以包括RSRQ、RSRP、RSSI等中的一个或多个。
用于定位测量的RS包括但不限于：PRS、TRS、CSI-RS和DMRS。具体使用哪种RS进行定位测量可以是协议定义的，也可以是网络设备配置的，具体的方法本申请不做限定。
203、终端根据测量指示对RS进行测量。
终端根据上述收到的测量指示对RS进行测量。这里的测量包括前述定位测量中的一种或多种，在此不再赘述。
在一种可能的实现中，网络设备还可以为终端配置第一配置信息和第二配置信息，并向终端发送第一配置信息和第二配置信息。其中，第一配置信息和第二配置信息可以是在RRC连接时配置，并以RRC信令的方式发送的；也可以是在其它时候配置，并以其它方式发送的，如在LTE中的轻量级表示协议(lightweight presentation protocol，LPP)中，可以以LPP信令或LPP消息的方式发送，在5G中的新空口定位协议(new radio positioning protocol，NRPP)中，可以以NRPP信令或NRPP消息的方式进行发送。
第一配置信息为RS的配置信息，RS的配置信息可以包括RS的生成信息、类型信息、端口信息、时频资源信息、RS资源索引、RS所在小区的信息、RS所在的带宽部分(bandwidth part，BWP)、RS所在频点的信息、时域密度信息、序列生成信息、周期性信息、QCL信息、定时同步信息、功率配置信息、子载波间隔、小区空间指示信息、功率(或功率偏移)、RS分组信息等中的一个或多个。生成信息为用于生成RS的信息，如生成序列的初始值。类型信息用于指示RS的类型，如CSI-RS，SSB等。端口信息用于指示RS使用的端口的信息，如RS使用了1、2、4或8端口。时频资源信息用于指示RS占用的资源单元(resource element，RE)的时域和频域位置。时域密度信息用于指示RS占用时域资源的周期性、周期大小、周期偏移、每个周期包含的符号或时隙个数。QCL信息用于指示RS的QCL关系，如空间QCL。 定时同步信息为接收RS要使用的定时锚点，例如某个SSB或CSI-RS资源。功率配置信息用于指示RS的发送功率，或与其他RS的功率偏差。小区空间指示信息用于指示终端哪些小区可以使用相同的接收波束或接收面板进行接收，其形式可以是小区分组，例如，可以将使用相同的接收波束或接收面板接收的小区分为一组，分组内容可以是小区的物理ID、小区ID等。功率或功率偏移用于计算路损、识别非直射径(non-line-of-sight，NLOS)等。RS分组信息可以包括具有QCL关系的RS的分组，即具有QCL关系的RS为一组。RS分组信息也可以是其他的分组指示，例如，用同一个接收波束进行接收的RS等，具体的本申请对RS分组方法不做约束。
第二配置信息为RS测量上报的配置信息，可以包括测量规则、测量配置、测量辅助信息、测量模式、需要测量的波束资源集合、需要测量的波束资源数量、需要测量的小区、需要测量的小区标识集合、需要测量的小区数量、上报的波束的信号质量的阈值、上报的测量结果的数量等中的一个或多个。上报的波束的信号质量的阈值可以包括发送波束上报门限和/或接收波束上报门限。上报的测量结果的数量可以包括最小发送波束上报数量、最大发送波束上报数量、最小接收波束上报数量、最大接收波束上报数量、上报的测量结果的组的数量和选择上报测量结果的组的准则中的一个或多个。
最小发送波束上报数量即需要上报的发送波束的最小数量，可以是所有上报的发送波束的数量，也可以是每组测量结果需要上报的发送波束的数量。最大发送波束上报数量即需要上报的发送波束的最大数量，可以是所有上报的发送波束的数量，也可以是每组测量结果需要上报的发送波束的数量。接收波束上报门限即需要上报的接收波束的测量结果要大于接收波束上报门限，可以是需要上报的接收波束的所有测量结果经过滤波后的值要大于接收波束上报门限。最小接收波束上报数量即需要上报的接收波束的最小数量。最大接收波束上报数量即需要上报的接收波束的最大数量。选择上报测量结果的组的准则可以为RS的数量最多、信号强度最强、RS的信号强度强且数量最多、信号强度大于阈值等中的任意一种。
第二配置信息可以包括发送波束上报门限，也可以包括发送波束上报门限和最小发送波束上报数量，还可以包括发送波束上报门限和最大发送波束上报数量，还可以包括发送波束上报门限、最小发送波束上报数量和最大发送波束上报数量，还可以包括接收波束上报门限，还可以包括接收波束上报门限和最小接收波束上报数量，还可以包括接收波束上报门限和最大接收波束上报数量，还可以包括接收波束上报门限、最小接收波束上报数量和最大接收波束上报数量，还可以包括选择上报测量结果的组的准则，还可以包括上报的测量结果的组的数量，还可以包括以上信息的其它组合，本实施例不作限定。
应理解，上述测量指示是通知终端进行定位测量，在进行定位测量之前，网络设备应该将RS的配置信息发送给终端，即，向终端发送第一配置信息，第一配置信息通常在测量指示之前就应该配置好。终端接收到测量指示的时候，已经获得了需要测量的RS的配置信息。
因此，终端在进行RS测量的时候，根据测量指示对第一配置信息所配置的RS进行测量。
上述测量指示和第一配置信息可以是同时发送给终端的，也可以是分开发送的。比如，测量指示通过PDCCH发送给终端，而第一配置信息可以通过RRC或MAC CE发送给终端。 具体的本申请不做限定。
进一步地，终端对RS进行测量之后，会获得一个或多个RS的测量结果，为便于终端对测量结果进行上报，因此，网络设备需要为终端配置RS测量上报的配置信息，即，第二配置信息。通过第二配置信息，终端设备可以对测量的RS进行层1或层3的滤波，从而决定需要报告的测量结果。
第一配置信息可以是同时配置的，也可以是在一个消息里进行配置的，例如，通过RRC进行配置。也可以是通过分开的RRC消息分开配置，还可以通过MAC CE进行配置，本申请不做约束。
例如，第二配置信息包括测量规则，测量规则为使用第一径或最强径进行测量，此时，终端只需要对第一径或最强径中的RS进行测量，而不需要对所有信道路径中的RS进行测量。具体地，终端可以通过RS对信道进行估计，之后可以选择功率最大、SINR最大或者功率和SINR综合最大的信道为最强径，也可以选择功率大于功率门限和/或SINR大于信噪比门限的信道中时延最小的信道为第一径。其中，功率门限和/或SINR门限可以由终端确定，也可以由网络设备确定。在测量规则包括多个的情况下，终端在确定要使用的测量规则之后，可以向网络设备发送确定的测量规则。此外，可以将其它相关信息一起发送给网络设备。例如，终端使用第一径进行测量的情况下，可以将第一径的时延信息、SINR信息、置信度等一起发送给网络设备。
204、终端通过层1和/或层3滤波器对同一个接收波束所接收的一个或多个发送波束的测量结果进行滤波得到M组测量结果。
测量结果的测量量可以包括RSRP、RSRQ、RSSI、SINR等中的一个或多个。终端测量得到的测量结果中不同RS由于传输信道的不同，终端接收到RS时会存在质量上的不同，不同的信号质量会导致不同的定位测量结果。因此，为了得到质量较好的测量结果，终端对RS进行测量得到测量结果之后，可以通过层1和/或层3滤波器对同一个接收波束所接收的一个或多个发送波束的测量结果进行滤波得到M组测量结果，以便终端可以上报经过层1和/或层3滤波器滤波后的测量结果。层1和/或层3滤波器可以由终端配置，也可以由网络设备配置。其中，M为大于或等于1的整数。
在一种可能的实现中，请参阅图3，图3是本发明实施例公开的一种通过层1和/或层3滤波器进行滤波的示意图。如图3所示，在对测量结果进行滤波前，先要对测量结果进行分组，即将使用同一个接收波束进行测量得到的测量结果分为一组，也即以接收波束为单位进行分组，因此，使用了几个接收波束进行测量将被分为几组。之后将每组测量结果通过层1和/或层3滤波器进行滤波。
终端在进行层1和/或3滤波的时候，将同一个接收波束测量到的RS采用同一个信号质量的阈值作为参考来进行滤波，根据第二配置信息的配置，选择出符合配置要求的测量结果。符号要求的测量结果包括，如同一个接收波束测量到的N个测量结果，N为大于等于1的整数，或者同一个接收波束所有大于信号质量的阈值的所有波束，或者同一个接收波束检测到的所有波束的测量结果。具体的依赖于配置或协议定义，本申请不做限定。
应理解，上述层1和/或3滤波可以是独立执行的步骤，不依赖于前述步骤而独立形成层3滤波方案。
205、终端向网络设备发送一组或多组测量结果。
终端通过层1和/或层3滤波器对同一个接收波束所接收的一个或多个发送波束的测量结果进行滤波得到M组测量结果之后，可以从M组测量结果中选择一组或多组测量结果向网络设备进行上报。但终端向网络设备上报的一组或多组测量结果中每组测量结果所对应的RS必须具有关联关系，关联关系包括每组测量结果为同一个接收波束的测量结果。此外，关联关系还包括：每组测量结果所对应的RS为满足以下条件中的任一条件的RS：关联到同一TCI状态；属于同一个小区；属于一个小区分组；属于同一类型；属于一个RS集合；存在空间QCL关系；与同一个RS具有空间QCL关系；与同一个小区的RS具有空间QCL关系；关联到包括空间QCL的TCI状态，且空间QCL对应的RS资源属于同一个小区或存在空间QCL关系。
从M组测量结果中选择一组或多组测量结果向网络设备进行上报，可以是从M组测量结果中的每组测量结果包括的发送波束中选择满足第二配置信息和关联关系要求的发送波束得到的选择的M组测量结果中的一组或多组测量结果进行上报，也可以是根据第二配置信息和关联关系从M组测量结果中选择一组或多组测量结果进行上报，还可以是先从M组测量结果中的每组测量结果包括的发送波束中选择满足第二配置信息和关联关系要求的发送波束得到选择的M组测量结果，之后继续根据第二配置信息从选择的M组测量结果中选择一组或多组测量结果进行上报。
请参阅图4，图4是本发明实施例公开的一种对测量结果进行选择的示意图。如图4所示，在第二配置信息包括发送波束上报门限、最小发送波束上报数量或最大发送波束上报数量中的一个或多个的情况下，针对M组测量结果中的每组测量结果，可以根据发送波束上报门限、最小发送波束上报数量或最大发送波束上报数量中的至少一个从发送波束中选择满足上报条件的发送波束，之后得到新的M组测量结果。举例说明，在第二配置信息包括发送波束上报门限，而未包括最小发送波束上报数量和最大发送波束上报数量的情况下，从第一组测量结果包括的发送波束中选择测量结果大于发送波束上报门限的发送波束为第一组测量结果的上报发送波束，第一组测量结果为M组中测量结果中的任一组测量结果。在第二配置信息还包括接收波束上报门限、最小接收波束上报数量或最大接收波束上报数量中至少一种的情况下，可以继续从得到的新的M组测量结果对接收波束进行选择，最后得到需要上报的一组或多组测量结果。
由于经过层1和/或层3滤波器得到的测量结果是以接收波束为单位进行分组的，因此，发送波束的选择可以主要是针对同一个接收波束对不同发送波束的测量结果进行选择，以便可以减少上报的数量，从而可以减少上报冗余量。
接收波束的选择主要是为了保证测量质量。在第二配置信息包括接收波束上报门限的情况下，可以对一个接收波束对应的多个发送波束的测量结果先进行滤波，得到的波束质量大于接收波束上报门限的情况下，可以上报这一组测量结果。其中，此处的滤波为广义的滤波操作，可以是线性平均、取测量结果中的最大值等。
终端还可以向网络设备发送一组或多组测量结果中的接收波束的信息，如TCI状态索引、CSI-RS资源索引、SRS资源索引以及这些索引对应的载波信息和BWP。在上述信息中不包括载波信息的情况下，网络设备可以默认这些索引对应的载波信息为当前服务小区中 主小区的载波信息。此外，终端还可以向网络设备发送终端的坐标信息，如终端的朝向信息、终端天线面板的朝向信息、接收或发送上行或下行RS的相对空间信息或绝对空间信息等。其中，空间信息可以通过信号测量、传感器等获取到。
基于图1所示的网络架构，请参阅图5，图5是本发明实施例公开的一种通信方法的流程示意图。如图5，该通信方法可以包括如下步骤。
501、网络设备向终端发送测量指示。
其中，步骤501与步骤201相同，详细描述请参考步骤201，在此不再详细赘述。
502、网络设备向终端发送用于定位测量的RS。
其中，步骤502与步骤202相同，详细描述请参考步骤202，在此不再详细赘述。
503、网络设备向终端发送用于指示使用同一个接收波束进行测量的指示信息。
网络设备可以为终端配置用于指示终端使用同一个接收波束进行测量的指示信息，并向终端发送该指示信息。
在一种可能的实现中，该指示信息可以为第一配置信息，第一配置信息为RS的配置信息，RS的配置信息可以包括RS的生成信息、类型信息、端口信息、时频资源信息、RS资源索引、RS所在小区的信息、RS所在的BWP、RS所在频点的信息、时域密度信息、序列生成信息、周期性信息、QCL信息、定时同步信息、功率配置信息、子载波间隔、小区空间指示信息、功率(或功率偏移)、RS分组信息等中的一个或多个。RS的配置信息的具体解释与上述相同，详细描述请参考步骤203，在此不再详细赘述。
第一配置信息可以包括一组或多组RS，一组或多组RS中每组RS的RS具有关联关系，关联关系可以包括每组RS使用同一个接收波束进行测量，关联关系还可以包括第一信息，第一信息为每组RS为满足第一条件的RS，第一条件为关联到同一TCI状态、属于同一小区、属于一个小区分组、属于同一类型、属于同一个RS集合、存在空间QCL关系、与同一个RS具有空间QCL关系、与同一个小区的RS具有空间QCL关系以及关联到包括空间QCL的TCI状态且空间QCL对应的RS资源属于同一个小区或存在空间QCL关系中的任意一个。
在网络设备配置第一配置信息时，已经根据第一信息对RS进行了明确分组的情况下，关联关系可以不包括第一信息。在网络设备配置第一配置信息时，未根据第一信息对RS进行明确分组的情况下，关联关系必须包括第一信息，以便终端根据第一信息确定需要测量的RS中的哪些RS属于同一组，从而进一步确定哪些RS需要使用同一个接收波束进行测量。其中，第一配置信息的配置和发送方式可以与步骤203中的相同，详细描述请参考步骤202，在此不再详细赘述。
在一种可能的实现中，该指示信息可以包括第一配置信息和指示信令，第一配置信息为RS的配置信息。第一配置信息可以包括一组或多组RS，指示信令用于指示第一配置信息包括的一组或多组RS中每组RS的RS具有关联关系，关联关系包括每组RS使用同一个接收波束进行测量。其中，指示信令可以为动态信令，可以通过PDCCH进行发送。第一配置信息的配置和发送方式与上述相同，RS的配置信息与上述相同，在此不再详细赘述。
同上述相同，在网络设备配置第一配置信息时，已经根据第一信息对RS进行了明确分组的情况下，关联关系可以不包括第一信息。在网络设备配置第一配置信息时，未根据第 一信息对RS进行明确分组的情况下，关联关系必须包括第一信息，以便终端根据第一信息确定需要测量的RS中的哪些RS属于同一组，从而进一步确定哪些RS需要使用同一个接收波束进行测量。其中，第一信息与上述相同，在此不再详细赘述。
在一种可能的实现中，该指示信息可以为指示信令，指示信令可以指示每次测量使用同一个接收波束进行测量，或者对存在关联关系的RS使用同一个接收波束进行测量。其中，关联关系包括第一信息。该关联关系可以由网络设备发送给终端，也可以由协议定义，本实施例不作限定。该指示指令可以通过高层信令，如RRC或MAC CE进行发送，还可以在PDCCH中进行指示。当通过PDCCH进行指示时，RS的关联关系应该已经被配置，指示信令仅指示采用同一个接收波束，或者指示具体的使用的接收波束。第一信息与上述相同，在此不再详细赘述。
504、终端根据测量指示和指示信息对RS进行测量。
网络设备还可以为终端配置第二配置信息，并向终端发送第二配置信息。第二配置信息与上述实施例中的第二配置信息相同，在此不再详细赘述。
终端接收到来自网络设备的RS、指示信息和测量指示之后，将根据测量指示和指示信息对RS进行测量，即根据第二配置信息和指示信息开始对RS进行测量，即对满足使用同一个接收波束测量的RS使用同一个接收波束进行测量。例如，对同一组中的RS可以使用同一个接收波束进行测量，对不同组中的RS可以使用不同的接收波束测量，也可以使用相同的接收波束进行测量。例如，对满足同一关联关系的RS可以使用同一个接收波束进行测量，对满足不同关联关系的RS可以使用不同的接收波束测量，也可以使用相同的接收波束进行测量。但是具体使用那个一接收波束进行测量，终端可以自行确定，也可以根据网络设备提供的其它信息确定，例如，网络设备可以指示一组RS与某特定SS块或CSI-RS资源是空间QCL，则终端可以根据该SS块或CSI-RS资源确定接收波束。
505、终端通过层1和/或层3滤波器对同一个接收波束所接收的一个或多个发送波束的测量结果进行滤波得到M组测量结果。
其中，步骤505与步骤204相同，详细描述请参考步骤204，在此不再详细赘述。
506、终端向网络设备发送一组或多组测量结果。
终端通过层1和/或层3滤波器对同一个接收波束所接收的一个或多个发送波束的测量结果进行滤波得到M组测量结果之后，可以是从M组测量结果中的每组测量结果包括的发送波束中选择满足第二配置信息要求的发送波束得到的选择的M组测量结果中的一组或多组测量结果进行上报，也可以是根据第二配置信息从M组测量结果中选择一组或多组测量结果进行上报，还可以是先从M组测量结果中的每组测量结果包括的发送波束中选择满足第二配置信息要求的发送波束得到选择的M组测量结果，之后继续根据第二配置信息从选择的M组测量结果中选择一组或多组测量结果进行上报。
请参阅图4，图4是本发明实施例公开的一种对测量结果进行选择的示意图。如图4所示，在第二配置信息包括发送波束上报门限、最小发送波束上报数量或最大发送波束上报数量中的一个或多个的情况下，针对M组测量结果中的每组测量结果，可以根据发送波束上报门限、最小发送波束上报数量或最大发送波束上报数量中的至少一个从发送波束中选择满足上报条件的发送波束，之后得到新的M组测量结果。举例说明，在第二配置信息包括发 送波束上报门限，而未包括最小发送波束上报数量和最大发送波束上报数量的情况下，从第一组测量结果包括的发送波束中选择测量结果大于发送波束上报门限的发送波束为第一组测量结果的上报发送波束，第一组测量结果为M组中测量结果中的任一组测量结果。在第二配置信息还包括接收波束上报门限、最小接收波束上报数量或最大接收波束上报数量中至少一种的情况下，可以继续从得到的新的M组测量结果对接收波束进行选择，最后得到需要上报的一组或多组测量结果。
由于经过层1和/或层3滤波器得到的测量结果是以接收波束为单位进行分组的，因此，发送波束的选择可以主要是针对同一个接收波束对不同发送波束的测量结果进行选择，以便可以减少上报的数量，从而可以减少上报冗余量。
接收波束的选择主要是为了保证测量质量。在第二配置信息包括接收波束上报门限的情况下，可以对一个接收波束对应的多个发送波束的测量结果先进行滤波，得到的波束质量大于接收波束上报门限的情况下，可以上报这一组测量结果。其中，此处的滤波为广义的滤波操作，可以是线性平均、取测量结果中的最大值等。
终端还可以向网络设备发送一组或多组测量结果中的接收波束的信息，如TCI状态索引、CSI-RS资源索引、SRS资源索引以及这些索引对应的载波信息和BWP。在上述信息中不包括载波信息的情况下，网络设备可以默认这些索引对应的载波信息为当前服务小区中主小区的载波信息。此外，终端还可以向网络设备发送终端的坐标信息，如终端的朝向信息、终端天线面板的朝向信息、接收或发送上行或下行RS的相对空间信息或绝对空间信息等。其中，空间信息可以通过信号测量、传感器等获取到。
