具体实施方式
为使本公开的目的、技术方案和优点更加清楚，下面将结合附图对本公开实施方式作进一步地详细描述。
图1示出了本公开一个示例性实施例提供的通信系统的框图，该通信系统可以包括：接入网12和终端设备14。
接入网12中包括若干个接入网设备120。接入网设备120可以是基站，基站是一种部署在接入网中用以为终端设备提供无线通信功能的装置。基站可以包括各种形式的宏基站，微基站，中继站，接入点等等。在采用不同的无线接入技术的系统中，具备基站功能的设备的名称可能会有所不同，例如在LTE系统中，称为eNodeB或者eNB；在5G NR-U系统中，称为gNodeB或者gNB。随着通信技术的演进，“基站”这一描述可能会变化。为方便本公开实施例中的描述，上述为终端设备14提供无线通信功能的装置统称为接入网设备。
终端设备14可以包括各种具有无线通信功能的手持设备、车载设备、可穿戴设备、计算设备或连接到无线调制解调器的其他处理设备，以及各种形式的用户设备，移动台(Mobile Station，MS)，终端(terminal device)等等。为方便描述，上面提到的设备统称为终端设备。接入网设备120与终端设备14之间通过某种空口技术互相通信，例如Uu接口。
本公开实施例的技术方案可以应用于各种通信系统，例如：全球移动通讯(Global System of Mobile Communication，GSM)系统、码分多址(Code Division  Multiple Access，CDMA)系统、宽带码分多址(Wideband Code Division Multiple Access，WCDMA)系统、通用分组无线业务(General Packet Radio Service，GPRS)、长期演进(Long Term Evolution，LTE)系统、LTE频分双工(Frequency Division Duplex，FDD)系统、LTE时分双工(Time Division Duplex，TDD)系统、先进的长期演进(Advanced long Term Evolution，LTE-A)系统、新无线(New Radio，NR)系统、NR系统的演进系统、非授权频段上的LTE(LTE-based access to Unlicensed spectrum，LTE-U)系统、NR-U系统、通用移动通信系统(Universal Mobile Telecommunication System，UMTS)、全球互联微波接入(Worldwide Interoperability for Microwave Access，WiMAX)通信系统、无线局域网(Wireless Local Area Networks，WLAN)、无线保真(Wireless Fidelity，WiFi)、下一代通信系统或其他通信系统等。
通常来说，传统的通信系统支持的连接数有限，也易于实现，然而，随着通信技术的发展，移动通信系统将不仅支持传统的通信，还将支持例如，设备到设备(Device to Device，D2D)通信，机器到机器(Machine to Machine，M2M)通信，机器类型通信(Machine Type Communication，MTC)，车辆间(Vehicle to Vehicle，V2V)通信以及车联网(Vehicle to Everything，V2X)系统等。本公开实施例也可以应用于这些通信系统。
在5G NR系统中，上述接入网设备120可以替换实现为N个传输接收点(Transmission Reception Point，TRP)。
图2示出了本公开一个示例性实施例提供的基于多个TRP或多个天线面板(multi-TRP/panel)的数据传输的示意图。
终端设备210处于服务小区(serving cell)之中，也处于邻小区(neighboring cell)之中。
其中，每个小区可以由不止一个TRP来覆盖。如图所示，serving cell由TRP1和TRP2联合覆盖，从而增大了serving cell的覆盖半径。neighboring cell由TRP3覆盖。
每个TRP可以设置有一个以上的天线面板(panel)。不同的天线面板的朝向可以不同，从而可以收发不同传输方向的波束，从而实现多空间分集。接入网设备可以使用多个panel(该多个panel可以来自同一个TRP或不同的TRP) 同时向终端设备210发送PDCCH。这种情况下，不同panel的发送方向不一样，所以终端设备210也需要使用不同的panel来接收PDCCH，那么接入网设备需要指示不同的传输配置指示(Transmission Configuration Indication，TCI)状态给终端设备，每个TCI状态对应终端设备的每个panel上的一个接收波束方向。通过上述基于波束(beam)的发送和接收方式，可以保证覆盖范围。
具体地，接入网设备可以通过信令指示TCI状态，从而告知终端设备210接收时需要使用的接收波束。其中，每个TCI状态对应一个参考信号(Reference Signal，RS)标识，该RS既可以是非零功率信道状态信息参考信号(Channel State Information Reference Signal，CSI-RS)，也可以是同步信号块(Synchronization Signal Block，SSB)或探测参考信号(Sounding Reference Signal，SRS)。
本公开实施例中，以该RS实现为CSI-RS为例进行说明。
移动通信对于频谱的需求在随着移动技术的发展而不断增加，5G毫米波目前采用的频段为26.25GHz到51.2GHz。对于高频段的应用，连续的超长带宽是信道容量提升的一项大的需求，目前5G的FR2频段最高使用400MHz的连续带宽，而在51.2GHz到66GHz的非授权频谱应用中，已经有使用达到2.16GHz的连续带宽。
NR系统中，在上下行通信设计中引入了带宽部分(BandWith Part，BWP)的概念，一个BWP用于表示在给定载频上给定子载波间隔下的连续频域资源块(Resource Block，RB)。
随着频率的增加，信号传输对信道的敏感度随之提高，目前的信道测量采用基站配置的CSI-RS参考信号，终端对配置了CSI-RS参考信号的资源元素(Resource Element，RE)进行功率测量并取平均值作为BWP的功率测量结果，从而向接入网设备上报功率测量结果，上报的颗粒度基于整个BWP的宽度。
这种对于整个BWP宽度上的参考信号取平均值的测量和上报方法，在大带宽的情况下，由于对多个RE上的功率进行了取平均的算法，抹去了信道中很多有差异的地方，而对于频率间隔较大的同一BWP内部的载波，没有办法很好的区别信道的差异性，所选择的信道存在通信条件较差的情况。特别是在频率增高，波束更窄，波束方向性更强，波束指向性更强的情况下，如果CSI-RS参考 信号无法很好的反馈信道参数并进行信道选择，将造成系统通信质量下降的情况。
本申请实施例中，对信道测量BWP的频域资源进行划分，得到多个子频段，从而终端在信道测量时，针对子频段进行测量并得到测量结果，从而细化了信道测量的粒度，提高了信道选择的准确率，以及提高了系统通信质量。
也即，终端首先确定信道测量时的频域测量精度，从而根据频域测量精度进行信道测量。其中，终端可以根据接入网设备的配置确定信道测量时的频域测量精度，或者，终端可以根据协议的定义确定信道测量时的频域测量精度；或者，终端可以自行确定信道测量时的频域测量精度，并向接入网设备指示自身进行信道测量时的频域测量精度。
图3是本公开一个示例性实施例提供的信道测量方法的流程图，以该方法被如图1所示的终端执行为例进行说明，如图3所示，该方法包括：
步骤301，确定终端进行信道测量时的频域测量精度。
可选地，终端确定频域测量精度的方式包括如下方式中的至少一种：
第一，终端接收接入网设备发送的配置信令，该配置信令中包括第一信息字段，第一信息字段用于指示终端进行信道测量时的频域测量精度。
第二，终端根据协议的预先定义确定频域测量精度。
第三，终端根据信道测量时的频域资源确定频域测量精度。
其中，无论是终端对频域测量精度进行确认，或者接入网设备对频域测量精度进行确定，频域测量精度的确认方式皆包括如下情况。
在一些实施例中，频域测量精度包括频域划分数量；或者，频域测量精度包括频域划分方式。
其中，当频域测量精度由接入网设备向终端配置时，频域划分数量是指接入网设备向终端配置的信道测量时的频域资源的划分数量；也即，接入网设备向终端配置的为一个数字，终端用于根据数字将信道测量时的频域资源划分为对应数量的子频段。频域划分方式是指接入网设备向终端设备配置的对信道测量时的频域资源进行划分的方式，如：该频域划分方式可以实现为频域划分比例。
当频域测量精度由终端确定时，则终端侧与接入网设备侧保持相同的确定 频域测量精度的方式。
本公开实施例中，以频域测量进度包括频域划分数量为例进行说明。
在一些实施例中，基站向终端配置用于进行信道测量的CSI-RS的时频资源位置，且基站还需要向终端配置基于CSI-RS进行测量后进行测量结果上报的信道状态信息(Channel State Information，CSI)报告(Report)，也即，基站需要配置信道状态信息报告参数(CSI-ReportConfig)，其中，CSI-ReportConfig中配置有reportFreqConfiguration，用于实现频域上报粒度的配置。本公开实施例中，在reportFreqConfiguration部分引入了频域划分数量参数(CSI-RSRPreport subband Num)，用于指示对信道测量时的频域资源进行划分时的划分数量。其中，频域划分数量参数(CSI-RSRPreport subband Num)即为上述第一信息字段。
终端接收接入网设备发送的配置信令，该配置信令中包括CSI-ReportConfig，并从中获取CSI-RSRPreportsubbandNum后，确定对信道测量时的频域资源进行划分的数量。示意性的，当CSI-RSRPreportsubbandNum取值为3时，表示终端在信道测量时，需要将频域资源划分为3个子频段进行分别测量。
在一些实施例中，在终端根据频域划分数量对频域资源进行划分时，包括平均划分方式和预设划分方式中的至少一种。
其中，平均划分方式即终端对频域资源进行平均划分，得到频域划分数量对应个数的子频段。示意性的，信道测量时的频域资源带宽为1GHz，频域划分数量为3，则将频域资源划分为3个子频段，每个子频段的带宽为333MHz。
预设划分方式即基站预先配置了针对信道测量的频域资源进行划分的方式，如：基站配置了终端针对频域资源进行划分时，以400MHz为基础带宽进行等长划分，并将等长划分至频域划分数量减1的数量后，将剩余的频域资源作为一个子频段。示意性的，信道测量时的频域资源带宽为1GHz，频域划分数量为3，首先从频域资源中划分出2个400MHz的子频段，并将剩余的200MHz频域资源作为一个子频段。
本公开实施例中，以对频域资源以平均划分方式进行划分为例进行说明。
在一些实施例中，上述频域划分数量CSI-RSRPreportsubbandNum是根据频域资源的带宽与预设带宽之间的比值确定的，在一些实施例中，频域划分数量CSI-RSRPreportsubbandNum为将频域资源的带宽与预设带宽之间的比值进行向 上取整得到的，其中，频域资源为用于信道测量的BWP的频域资源。
其中，预设带宽可以是根据接入网设备的精度需求而由接入网设备进行选择的带宽值；或者，预设带宽为当前频段支持的最小连续带宽。
示意性的，接入网设备向终端配置用于信道测量的CSI-RS时频资源，其中用于信道测量的BWP对应连续的1GHz带宽的频域资源，预设带宽为400MHz，则计算频域划分数量CSI-RSRPreportsubbandNum时，接入网设备计算1000/400向上取整的数值，得到的整数为3。从而接入网设备在向终端配置的CSI-ReportConfig中，频域划分数量CSI-RSRPreportsubbandNum配置为3。
在一些实施例中，频域划分数量在预设数量范围内，也即，接入网设备后者终端在进行频域划分数量的计算后，需要在预设数量范围内确定频域划分数量，示意性的，频域划分数量的取值范围为[1，8]，则当接入网设备计算得到的频域划分数量为9时，根据频域划分数量的取值范围，取数值8作为最终的频域划分数量。
在一些实施例中，当接入网设备通过向终端发送配置信令的方式对频域测量精度进行配置时，接入网设备通过PDCCH向终端发送配置信令。该配置信令可以实现为无线资源控制(Radio Resource Control，RRC)信令、媒体访问控制控制单元(Media Access Control Element，MAC CE)或物理层信令中的至少一种。
步骤302，根据频域测量精度对信道进行测量。
在一些实施例中，终端首先确定在信道测量时带宽部分BWP的频域资源，从而根据频域划分数量对频域资源进行划分，并对划分后频域资源内的子频段进行信道测量。
可选地，终端对划分后的子频段内携带参考信号CSI-RS的资源元素RE进行功率测量，得到子频段的功率测量结果。
针对每个子频段的功率测量过程，在子频段上对获得的参考信号的功率测量并进行平均处理，从而每个子频段得到一个功率测量结果。
在一些实施例中，终端向接入网设备发送子频段的功率测量结果，并根据功率测量结果进行下行接收波束的选择。其中，接入网设备用于根据功率测量结果进行下行发射波束的选择。终端根据功率测量结果进行下行接收波束的选择方式，与接入网设备根据功率测量结果进行下行发射波束的选择方式相同。 在一些实施例中，终端在对每个子频段进行功率测量得到功率测量结果后，向接入网设备上报信道状态信息参考信号的接收信号(Channel State Information-Reference Signal Received Power，CSI-RSRP)，其中，CSI-RSRP中包括每个子频段的功率测量结果。
在一些实施例中，终端在划分得到的子频段上对获得的参考信号功率测量结果做平均，每一个子频段可获得一个CSI-RSRP-subbandi作为测量结果。其中i的取值为[0，1，…，CSI-RSRPreportsubbandNum-1]。终端根据reportFreq Configuration的配置，向接入网设备上报CSI-RSRP-subbandi作为每个子频段的功率测量结果，从而接入网设备根据子频段的功率测量结果进行下行发射波束的选择。
综上所述，本公开实施例提供的信道测量方法，通过确定终端进行信道测量时的频域测量精度，从而终端根据频域测量精度对信道进行测量，避免在BWP粒度下进行信道测量而导致的信道通信条件较差的问题，对信道测量BWP的频域资源进行划分，得到多个子频段，从而终端在信道测量时，针对子频段进行测量并得到测量结果，从而细化了信道测量的粒度，提高了信道选择的准确率，以及提高了系统通信质量。

在一些实施例中，频域划分数量为接入网设备向终端配置的信道测量时的频域资源的划分数量；也即，接入网设备向终端配置的为一个数字，终端用于根据数字将信道测量时的频域资源划分为对应数量的子频段。或者，频域划分数量为终端根据信道测量时的频域资源确定的划分数量。
可选地，终端用于根据频域划分数量对用于进行信道测量的BWP频域资源进行平均划分。其中，平均划分方式即终端对频域资源进行平均划分，得到频域划分数量对应个数的子频段。示意性的，信道测量时的频域资源带宽为1GHz，频域划分数量为3，则将频域资源划分为3个子频段，每个子频段的带宽为 333MHz。
在一些实施例中，接入网设备或者终端首先确定终端在信道测量时带宽部分BWP的频域资源，根据频域资源的带宽与预设带宽之间的比值，确定频域划分数量。
在一些实施例中，频域划分数量为将频域资源的带宽与预设带宽之间的比值进行向上取整得到的，其中，频域资源为用于信道测量的BWP的频域资源。
其中，预设带宽可以是根据接入网设备的精度需求而由接入网设备进行选择的带宽值；或者，预设带宽为当前频段支持的最小连续带宽。
示意性的，以接入网设备向终端配置频域测量精度为例进行说明，接入网设备向终端配置用于信道测量的CSI-RS时频资源，其中用于信道测量的BWP对应连续的1GHz带宽的频域资源，预设带宽为400MHz，则计算频域划分数量CSI-RSRPreportsubbandNum时，接入网设备计算1000/400向上取整的数值，得到的整数为3。从而接入网设备在向终端配置的CSI-ReportConfig中，频域划分数量CSI-RSRPreportsubbandNum配置为3。
在一些实施例中，频域划分数量在预设数量范围内，也即，接入网设备根据频域资源的带宽与预设带宽之间的比值，需要在预设数量范围内确定频域划分数量。可选地，接入网设备在进行频域划分数量的计算后，需要在预设数量范围内确定频域划分数量，示意性的，频域划分数量的取值范围为[1，8]，则当接入网设备计算得到的频域划分数量为9时，根据频域划分数量的取值范围，取数值8作为最终的频域划分数量。
步骤402，接收终端发送的基于参考信号的接收信号的测量结果，测量结果中包括终端基于频域测量精度测量得到的子频段的功率测量结果。
终端用于根据频域测量精度对用于信道测量的频域资源进行划分，得到至少两个子频段，并针对每个子频段进行功率测量。
可选地，终端对划分后的子频段内携带参考信号CSI-RS的资源元素RE进行功率测量，得到子频段的功率测量结果。
针对每个子频段的功率测量过程，在子频段上对获得的参考信号的功率测量并进行平均处理，从而每个子频段得到一个功率测量结果。
在一些实施例中，终端向接入网设备发送子频段的功率测量结果，接入网设备根据功率测量结果进行下行发射波束的选择。终端根据功率测量结果进行 下行接收波束的选择方式，与接入网设备根据功率测量结果进行下行发射波束的选择方式相同。
在一些实施例中，终端在划分得到的子频段上对获得的参考信号功率测量结果做平均，每一个子频段可获得一个功率测量结果。终端向接入网设备上报每个子频段的功率测量结果，从而接入网设备根据子频段的功率测量结果进行下行发射波束的选择。
综上所述，本公开实施例提供的信道测量方法，通过确定终端进行信道测量时的频域测量精度，从而终端根据频域测量精度对信道进行测量，避免在BWP粒度下进行信道测量而导致的信道通信条件较差的问题，对信道测量BWP的频域资源进行划分，得到多个子频段，从而终端在信道测量时，针对子频段进行测量并得到测量结果，从而细化了信道测量的粒度，提高了信道选择的准确率，以及提高了系统通信质量。

终端向对BWP频域资源进行划分，得到至少两个子频段后，对每个子频段进行功率测量。
示意性的，以划分得到3个子频段为例进行说明，3个子频段中包括子频段a、子频段b和子频段c，分别占用BWP频域资源中的333MHz。终端对这些子频段上获得的参考信号CSI-RS的每个RE进行功率测量，并对RE的功率测量结果取平均，每一个子频段可获得一个CSI-RSRP-subband作为测量结果，如：子频段a测量得到CSI-RSRP-subband1作为功率测量结果，子频段b测量得到CSI-RSRP-subband2作为功率测量结果，子频段c测量得到CSI-RSRP-subband3作为功率测量结果，共三个测量结果。
