具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述。
应理解，本申请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LTE系统、LTE频分双工(Frequency Division Duplex，FDD)系统、LTE时分双工(Time Division Duplex，TDD)、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、新无线(New Radio，NR)或未来的5G系统等。
特别地，本申请实施例的技术方案可以应用于各种基于非正交多址接入 技术的通信系统，例如稀疏码多址接入(Sparse Code Multiple Access，SCMA)系统、低密度签名(Low Density Signature，LDS)系统等，当然SCMA系统和LDS系统在通信领域也可以被称为其他名称；进一步地，本申请实施例的技术方案可以应用于采用非正交多址接入技术的多载波传输系统，例如采用非正交多址接入技术正交频分复用(Orthogonal Frequency Division Multiplexing，OFDM)、滤波器组多载波(Filter Bank Multi-Carrier，FBMC)、通用频分复用(Generalized Frequency Division Multiplexing，GFDM)、滤波正交频分复用(Filtered-OFDM，F-OFDM)系统等。
本申请实施例中的终端设备可以指用户设备(User Equipment，UE)、接入终端、用户单元、用户站、移动站、移动台、远方站、远程终端、移动设备、用户终端、终端、无线通信设备、用户代理或用户装置。接入终端可以是蜂窝电话、无绳电话、会话启动协议(Session Initiation Protocol，SIP)电话、无线本地环路(Wireless Local Loop，WLL)站、个人数字处理(Personal Digital Assistant，PDA)、具有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、车载设备、可穿戴设备，未来5G网络中的终端设备或者未来演进的公用陆地移动通信网络(Public Land Mobile Network，PLMN)中的终端设备等，本申请实施例并不限定。
本申请实施例中的网络设备可以是用于与终端设备通信的设备，该网络设备可以是GSM或CDMA中的基站(Base Transceiver Station，BTS)，也可以是WCDMA系统中的基站(NodeB，NB)，还可以是LTE系统中的演进型基站(Evolutional NodeB，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，或者该网络设备可以为中继站、接入点、车载设备、可穿戴设备以及未来5G网络中的网络设备或者未来演进的PLMN网络中的网络设备等，本申请实施例并不限定。
图1是本申请实施例一个应用场景的示意图。图1中的通信系统可以包括终端设备10和网络设备20。网络设备20用于为终端设备10提供通信服务并接入核心网，终端设备10通过搜索网络设备20发送的同步信号、广播信号等而接入网络，从而进行与网络的通信。图1中所示出的箭头可以表示通过终端设备10与网络设备20之间的蜂窝链路进行的上/下行传输。
对于两个天线端口，如果通过天线端口之一发送符号的无线电信道的大 尺度特性可从通过另一天线端口发送符号的无线电信道推断，则这两个天线端口可被视为准共址。所述大尺度特性，即本文中提到的QCL信息包括以下参数中的至少一种：多普勒频移(Doppler shift)、多普勒扩展(Doppler spread)、平均时延(average delay)、延时扩展(delay spread)和以及空间接收参数(Spatial Rx parameter)中的至少一种。即当两个天线端口为QCL时，这意味着一个天线端口的无线电信道的大尺度特性对应于另一个天线端口的无线电信道的大尺度特性。考虑发送参考信号(Reference Signal，RS)的多个天线端口，当发送两种不同类型的RS的天线端口为QCL时，一个天线端口的无线电信道的大尺度特性可由另一天线端口的无线电信道的大尺度特性代替。
假设A为参考信号，B为目标信号，如果B关于上述大尺度参数与A准共址，则UE可以从A估算出该准共址的大尺度参数，从而B可以利用该大尺度参数进行后续操作。例如，UE可以执行以下操作：
关于时延扩展和多普勒扩展，UE可将针对一个天线端口的无线电信道的功率-时延概述、时延扩展和多普勒频谱和多普勒扩展估计结果等同地应用于用于针对另一天线端口的无线电信道的信道估计的维纳滤波器。
关于频移和接收定时，UE可对一个天线端口执行时间和频率同步，然后将相同的同步应用于针对另一天线端口的解调。
关于平均接收功率，UE可对两个或更多天线端口的参考信号接收功率(Reference Signal Receiving Power，RSRP)测量取平均值。
关于空间接收参数，UE可以将一个天线端口传输的信号使用的波束信息应用于另一个天线端口传输的信号上。例如，UE接收两个天线端口上信号所用的波束可以相同。
而在目前的NR设计中，网络可以配置一些资源用来进行CSI测量。主要包括用于信道测量的CSI-RS资源和用于干扰测量的CSI-RS资源。在一次CSI测量中，UE对用于信道测量的CSI-RS资源以及用于干扰测量的CSI-RS资源的空间参数进行了QCL假设。也就是说，用于信道测量的CSI-RS资源以及用于干扰测量的CSI-RS具有空间QCL，或者用于信道测量的CSI-RS资源以及用于干扰测量的CSI-RS关于空间接收参数具有QCL关联。网络也可以为CSI-RS资源进行QCL假设的配置。以A为参考信号，B为目标信号为例，在B或者含有B的集合配置中，可以携带相应的QCL假设的配置， 具体配置方式可以如下形式：
包含A和参数类型X，则可以认为A和B关于参数X是准共址的。
包含A1和参数类型X1，A2和参数类型X2，则可以认为A1与B关于参数类型X1是准共址的，以及A2与B关于参数类型X2是准共址的。
其中，参数类型X、参数类型X1和参数类型X2可以是上述大尺度特性中的至少一种参数。
图2示出了本申请实施例的CSI测量的方法100的示意性框图。如图2所示，该方法100包括以下部分或全部内容：
S110，终端设备假设第一信道状态信息参考信号CSI-RS与第二CSI-RS关于空间接收参数具有准共址QCL关联，该第一CSI-RS和该第二CSI-RS分别为在一次CSI测量中用于信道测量的参考信号和用于干扰测量的参考信号。
S120，该终端设备根据该第一CSI-RS与该第二CSI-RS之间的QCL信息进行该CSI测量。
具体地，在一次CSI测量中，UE首先假设用于信道测量的CSI-RS和用于干扰测量的CSI-RS空间QCL，或用于信道测量的CSI-RS与用于干扰测量的CSI-RS关于空间接收参数具有QCL关联。也就是说，UE可以基于这两类CSI-RS中的任何一类的空间接收参数，对另一类的CSI-RS进行测量。例如，UE可以使用用于信道测量的CSI-RS的接收波束接收用于干扰测量的CSI-RS，或者UE也可以使用用于信道测量的CSI-RS的接收波束进行用于干扰测量的CSI-RS的波束测量。
可以将QCL假设分为两类，第一类QCL假设对应的参数可以是空间接收参数，而第二类QCL假设对应的参数可以是多普勒频移、多普勒扩展、平均时延和延时扩展中的至少一种。
也就是说，在本申请实施例中，UE至少进行的是第一类QCL假设。
下面以用于信道测量的CSI-RS，即本文中的第一CSI-RS为参考信号，用于干扰测量的CSI-RS，即本文中的第二CSI-RS为目标信号为例，详细描述本申请实施例的技术方案。
可选地，网络设备可以不为第二CSI-RS配置第一类QCL假设，那么UE可以根据自己进行的第一类QCL假设进行该CSI的测量。具体地，UE可以使用自己假设的具有QCL关联的第一CSI-RS与第二CSI-RS之间的空 间接收参数进行CSI的测量。也就是说，UE可以将第一CSI-RS的空间接收参数作为第二CSI-RS的空间接收参数，即可以使用第一CSI-RS的空间接收参数进行干扰测量。
可选地，网络设备也可以不为第二CSI-RS配置第二类QCL假设，那么UE可以不使用第二类QCL假设进行CSI的测量。UE也可以进行第二CSI-RS的第二类QCL假设。进而，UE就可以根据UE假设的该第二CSI-RS假设进行CSI测量。UE也可以不使用第二类QCL假设进行CSI测量。例如，UE可以不使用第二类QCL假设进行CSI干扰测量。
UE也可以不进行第二CSI-RS的第一类QCL假设和/或第二类QCL假设。网络设备可以为该第二CSI-RS配置第一类QCL假设和/或第二类QCL假设。
可选地，在本申请实施例中，该方法还包括：该终端设备接收网络设备发送的第一配置信息，该第一配置信息用于指示该网络设备在该第一CSI-RS与该第二CSI-RS之间配置的第二类QCL假设，该第二类QCL假设对应的参数包括以下参数中的至少一种参数：多普勒频移、多普勒扩展、平均时延和时延扩展；该终端设备根据该第一CSI-RS与该第二CSI-RS之间的QCL信息进行该CSI测量，包括：该终端设备根据该第一配置信息指示的第二类QCL假设对应的参数和该终端设备假设的具有QCL关联的该第一CSI-RS与该第二CSI-RS之间的空间接收参数进行该CSI测量。
例如，UE为第二CSI-RS进行了第一类QCL假设，网络设备只为第二CSI-RS配置了第二类QCL假设，那么UE就可以根据自己进行的第一类QCL假设以及网络设备配置的第二类QCL假设进行CSI的测量。再例如，UE也可以为第二CSI-RS进行了第一类QCL假设，也为第二CSI-RS进行了第二类QCL假设，并且网络设备也为第二CSI-RS配置了第二类QCL假设，那么UE可以根据UE进行的第一类QCL假设以及网络设备配置的第二类QCL进行CSI的测量。
可选地，在本申请实施例中，该方法还包括：该终端设备接收网络设备发送的第二配置信息，该第二配置信息用于指示该网络设备为该第二CSI-RS配置的第一类QCL假设，该第一类QCL假设对应的参数为空间接收参数；该终端设备根据该第一CSI-RS与该第二CSI-RS之间的QCL信息进行该CSI测量，包括：若该第二配置信息指示的第一类QCL假设为该第一CSI-RS与 该第二CSI-RS之间的第一类QCL假设，该终端设备根据该第二配置信息指示的第一类QCL假设对应的参数进行该CSI测量。
可选地，在本申请实施例中，该方法还包括：若该第二配置信息指示的第一类QCL假设非该第一CSI-RS与该第二CSI-RS之间的第一类QCL假设，该终端设备确定该第二配置信息为不期望接收的配置信息。进一步地，该终端设备根据该终端设备假设的具有QCL关联的该第一CSI-RS与该第二CSI-RS之间的空间接收参数进行该CSI测量。
再例如，UE也可以为第二CSI-RS进行了第一类QCL假设，也为第二CSI-RS进行了第二类QCL假设，并且网络设备也为第二CSI-RS配置了第一类QCL假设和第二类QCL假设，那么UE首先需要判断UE进行的第一类QCL假设和网络设备指示的第一类QCL假设是不是属于相同的两个CSI-RS之间的QCL关联，如果是相同的两个CSI-RS之间的QCL关联，那么UE就可以直接根据网络设备配置的第一类QCL假设和第二类QCL假设进行CSI的测量。如果UE进行的第一类QCL假设和第二类QCL假设不是属于相同的两个CSI-RS之间的QCL关联，那么UE则认为接收到的网络设备的配置是一个错误的配置，UE可以不用管网络设备为第二CSI-RS配置的第一类QCL假设。UE也可以直接就使用UE进行的第一类QCL假设以及网络设备配置的第二类QCL假设进行CSI的测量。
可选地，在本申请实施例中，该第一CSI-RS为用于信道测量的非零功率CSI-RS(Non-Zero Power CSI-RS，NZP CSI-RS)，该第二CSI-RS为用于干扰测量的非零功率CSI-RS和/或CSI干扰测量(CSI based interference measurement，CSI-IM)。
因此，本申请实施例的CSI测量的方法，有利于改善UE的接收性能。
图3示出了本申请实施例的CSI测量的方法200的示意性框图。如图3所示，该方法200包括以下部分或全部内容：
S210，网络设备向终端设备发送配置信息，所述配置信息用于指示第一信道状态信息参考信号CSI-RS或第二CSI-RS的QCL关联关系，所述QCL关联关系包括第一类QCL假设和/或第二类QCL假设，所述第一类QCL假设对应的参数为空间接收参数，所述第二类QCL假设对应的参数包括以下参数中的至少一种参数：多普勒频移、多普勒扩展、平均时延和时延扩展，所述第一CSI-RS和所述第二CSI-RS分别为在一次CSI测量中用于信道测量 的参考信号和用于干扰测量的参考信号。
因此，本申请实施例的CSI测量的方法，有利于改善UE的接收性能。
可选地，在本申请实施例中，所述QCL关联关系为第一CSI-RS与所述第二CSI-RS之间的QCL假设。
可选地，在本申请实施例中，所述第一CSI-RS为用于信道测量的非零功率CSI-RS，所述第二CSI-RS为用于干扰测量的非零功率CSI-RS。
