在一种可能的设计中，该测量结果还可以包括该组测量资源对应的索引。
在一种可能的设计中，多个预编码矩阵具有不同的优先级。通过上述设计，终端设备在上报资源不足时，可以优先上报优先级较高的预编码矩阵。
在一种可能的设计中，预编码矩阵的优先级与该预编码矩阵对应测量资源的资源索引呈正相关，例如，预编码矩阵对应的测量资源的资源索引越大，预编码矩阵的优先级越高。
在一种可能的设计中，预编码矩阵的优先级与该预编码矩阵对应测量资源的配置顺序呈正相关，例如，预编码矩阵对应的测量资源的配置顺序越靠前，预编码矩阵的优先级越高。
在一种可能的设计中，预编码矩阵的优先级与该预编码矩阵对应测量资源在资源集合中的顺序呈正相关，例如，预编码矩阵对应的测量资源在资源集合中的顺序越靠前，预编码矩阵的优先级越高。

具体实施方式
1、波束
波束在新无线(new radio，NR)协议中的体现可以是空域滤波器(spatial domain filter)，或者称空间滤波器(spatial filter)，或称空间参数(spatial parameter)(如空间接收参数，和空间发送参数)。用于发送信号的波束可以称为发送波束(transmission beam，Tx beam)，也可以称为空域发送滤波器(spatial domain transmission filter)，空间发送滤波器(spatial transmission filter)，空域发送参数(spatial domain parameter)或空间发送参数(spatial transmission parameter)。用于接收信号的波束可以称为接收波束(reception beam，Rx beam)，也可以称为空域接收滤波器(spatial domain reception filter)，空间接收滤波器(spatial reception filter)，空域接收参数(spatial domain reception parameter)或空间接收参数(spatial reception parameter)。
发送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。
此外，波束可以是宽波束，或者窄波束，或者其他类型波束。形成波束的技术可以是波束赋形技术或者其他技术。波束赋形技术具体可以为数字波束赋形技术、模拟波束赋形技术或者混合数字或者模拟波束赋形技术等。
波束一般和资源对应，例如进行波束测量时，网络设备通过不同的资源来测量不同的波束，终端设备反馈测得的资源质量，网络设备就知道对应的波束的质量。在数据传输时，波束信息也是通过其对应的资源来进行指示的。例如网络设备通过下行控制信息(downlink control information，DCI)的传输配置指示(transmission configuration indicator，TCI)中资源，来指示终端设备的物理层下行共享信道(physical downlink shared channel，PDSCH)波束的信息。
可选地，可以将具有相同或者类似的通信特征的多个波束视为是一个波束。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。形成一个波束的一个或多个天线端口也可以看作是一个天线端口集。
在下行波束测量中，发送波束是指网络设备的发送波束，接收波束可以指终端设备的接收波束。在上行波束测量中，发送波束是指终端设备的发送波束，接收波束可以指网络设备的接收波束。在波束测量中，一个波束可以对应一个资源，这种方式中可以以资源的索引来标识该资源对应的波束。或者，一个波束可以对应多个资源。
2、准共址(quasi-collocation，QCL)：
准共址，也可以称为准共站、同位置。
具有QCL关系的天线端口对应的信号中可以具有相同的或相近的空间特性参数(或称为参数)，或者，一个天线端口的空间特性参数(或称为参数)，可以用于确定与该天线端口具有QCL关系的另一个天线端口的空间特性参数(或称为参数)，或者，两个天线端口具有相同的或相似的空间特性参数(或称为参数)，或者，两个天线端口间的空间特性参数(或称为参数)差小于某阈值。
应理解，满足QCL关系的两个参考信号或信道的空间特性参数是相同的(或相近的，或相似的)，从而基于该源参考信号资源索引可推断出目标参考信号的空间特性参数。
还应理解，满足空间相关性信息的两个参考信号或信道的空间特性参数是相同的(或相近的，或相似的)，从而基于该源参考信号资源索引可推断出目标参考信号的空间特性 参数。
其中，空间特性参数包括以下参数中的一种或多种：
入射角(angle of arrival，AoA)、主(dominant)入射角AoA、平均入射角、入射角的功率角度谱(power angular spectrum，PAS)、出射角(angle of departure，AoD)、主出射角、平均出射角、出射角的功率角度谱、终端设备发送波束成型、终端设备接收波束成型、空间信道相关性、网络设备发送波束成型、网络设备接收波束成型、平均信道增益、平均信道时延(average delay)、时延扩展(delay spread)、多普勒扩展(Doppler spread)、多普勒频移(doppler shift)、空间接收参数(spatial Rx parameters)等。
其中，上述角度可以为不同维度的分解值，或不同维度分解值的组合。
现有标准中定义了四种类型的QCL，网络设备可以同时给终端设备配置一个或多种类型的QCL，如QCL type A+D，C+D：
QCL types A：Doppler shift，Doppler spread，average delay，delay spread。
QCL types B：Doppler shift，Doppler spread。
QCL types C：average delay，Doppler shift。
QCL types D：Spatial Rx parameter。
当QCL关系指类型D的QCL关系时，可以认为是空域QCL。当天线端口满足空域QCL关系时，可以是下行信号的端口和下行信号的端口之间，或上行信号的端口和上行信号的端口之间的QCL关系(也可以称为spatial relation)，可以是两个信号具有相同的AoA或AoD，用于表示具有相同的接收波束或发射波束。又例如对于下行信号和上行信号间或上行信号与下行信号的端口间的QCL关系，可以是两个信号的AOA和AOD具有对应关系，或两个信号的AOD和AOA具有对应关系，即可以利用波束互易性，根据下行接收波束确定上行发射波束，或根据上行发射波束确定下行接收波束。
具有空域QCL关系的端口上传输的信号还可以理解为使用相同的空间滤波器(spatial filter)接收或发送信号。空间滤波器可以为以下至少之一：预编码，天线端口的权值，天线端口的相位偏转，天线端口的幅度增益。
具有空域QCL关系的端口上传输的信号还可以理解为具有对应的波束对连接(beam pair link，BPL)，对应的BPL包括以下至少之一：相同的下行BPL，相同的上行BPL，与下行BPL对应的上行BPL，与上行BPL对应的下行BPL。
因此，空间接收参数(即，类型D的QCL)可以理解为用于指示接收波束的方向信息的参数。
在本申请的举例中，某些参数的对应关系也可以应用于QCL描述下的场景。
应理解，本申请中适用于QCL假设的场景，也可以是两个参考信号，进一步或者是传输对象间的关联关系。
3、测量资源
信道对应的测量资源可以是上行测量资源，也可以是下行测量资源。上行测量资源包括但不限于：探测参考信号(sounding reference signal，SRS)，解调参考信号(demodulation reference signal，DMRS)等等。下行测量资源包括但不限于：信道状态信息参考信号(channel state information reference signal，CSI-RS)、信道状态信息干扰测量(channel state information interference measurement，CSI-IM)、小区专用参考信号(cell specific reference signal，CS-RS)、UE专用参考信号(user equipment specific reference signal，US-RS)、DMRS、以及SS/PBCH  block等等。其中，SS/PBCH block可以简称为同步信号块(synchronization signal block，SSB)。
测量资源可以通过无线资源控制信令(radio resource control，RRC)信令配置。在配置结构上，一个测量资源可以是一个数据结构，包括其对应的上行/下行信号的相关参数，例如上行/下行信号的类型，承载上行/下行信号的资源粒，上行/下行信号的发送时间和周期，发送上行/下行信号所采用的端口数等。每一个上行/下行信号的测量资源具有一个索引，以标识该上行/下行信号的测量资源。可以理解的是，测量资源的索引也可以称为测量资源的标识，本申请实施例对此不作任何限制。
测量资源可以包括信道资源和干扰资源。
3.1、信道资源
信道资源是指网络设备配置的用于信道测量的资源。信道资源可以用于测量参考信号接收功率(reference signal received power，RSRP)，信道质量指示(chanel quality indicator，CQI)，信号干扰噪声比(signal to interference plus noise ratio，SINR)等信道信息。在上行信道测量中，信道资源可以是SRS资源。在下行信道测量中，信道资源可以是CSI-RS资源或SSB。在测量CQI和SINR时，还需要配置干扰资源。
3.2、干扰资源
干扰资源是指网络设备配置的用于信道测量的资源。在上行信道测量中，干扰资源可以是SRS资源。在下行信道测量中，干扰资源可以是CSI-RS资源，SSB或CSI-IM资源。在测量CQI和SINR等信道信息时，这些干扰资源作为干扰源，与信道资源一起计算CQI和SINR。例如，要测量一个信道资源在一个干扰资源的SINR时，可以以该信道资源的能量作为分子，该干扰资源的能量作为分母，来计算SINR。
4、信道测量
信道测量是R15协议中的一个测量流程，用于测量特定资源的信道状态信息，如CQI等，分为下行信道测量和上行信道测量。
4.1下行信道测量
下行信道测量主要包括四步。
S1、网络设备向终端设备发送测量配置信息。测量配置信息是网络设备通过无线资源控制(radio resource control，RRC)信令向终端发送的，主要包括两部分：资源配置信息和上报配置信息。资源配置信息是测量资源相关的信息，在协议里通过三级结构：资源配置(resourceConfig)或者资源配置(resourceSetting)-资源集(resourceSet)-资源(resource)进行配置。网络设备可以为终端设备配置一个或多个资源配置，每个资源配置包括一个或多个资源集，每个资源集可以包括一个或多个资源。每个资源配置/资源集/资源中都包括一个自己的索引。此外，还包括一些其他参数，如资源的周期，资源对应的信号类型等。每个资源可以包括一个或多个天线端口。上报配置信息是指测量结果上报相关的信息，在协议里通过上报配置(ReportConfig)进行配置。网络设备可以为终端设备配置一个或多个上报配置，每个上报配置包括都上报指标，上报时间和周期，上报格式等与上报相关的信息。此外，上报配置里还包括资源配置的索引，用于指示上报的结果是通过什么测量配置测得的。
信道测量中，要测量CQI时，还可以测量对应的干扰信号。干扰信号可以通过测量干扰资源来进行测量。干扰资源是和信道资源一起配置给终端设备的，分别配置在不同的 resource setting中。例如，RRC信令配置了两个resource setting，其中一个包含的信道资源，另一个包含的是干扰资源。干扰资源的类型有非零功率信道状态信息参考信号(non zero power CSI-RS，NZP CSI-RS)和CSI-IM两种。
还需要配置各个资源的波束信息，这样终端设备才知道各个资源对应的波束，以及确定应该采用什么接收波束来进行接收。波束信息是封装在TCI状态(TCI-state)中的，每个信道资源中都可以包括一个TCI-state，用于指示该资源的波束信息。干扰资源的波束信息不需要配置，而是默认采用其关联的信道资源的波束信息。例如，当采用CSI-IM资源作为干扰资源时，CSI-IM资源的数量必须等于信道资源的数量，并一一对应。每个CSI-IM默认采用其对应的信道资源的波束，终端设备会采用相同的接收波束来接收该信道资源和该CSI-IM资源。采用NZP CSI-RS资源作为干扰资源时，规定只能配置一个信道资源，所有NZP CSI-RS干扰资源都采用该信道资源的波束。
下面介绍R15协议里资源配置和上报配置的具体格式，以便于对测量配置信息进行进一步理解。

Figure PCTCN2021096796-appb-000002
S2、网络设备在测量配置信息所配置的资源对应的资源粒上发送下行信号，以使得终端设备通过测量下行信号，确定各资源对应的信道信息(即资源对应的波束的信道信息)。
S3、终端设备根据测量配置信息对下行信号进行测量，即测量什么资源，在哪些时频资源上进行测量，测量什么指标等。
S4、终端设备向网络设备发送波束测量报告。波束测量报告可以包括一个或多个资源的索引以及这些资源对应的信道信息，如CQI，秩指示(rank indication，RI)，预编码矩阵指示(precoding matrix indicator，PMI)，层指示(layer indicator，LI)等。

在移动通信系统(如5th generation，5G)中，进行数据传输之前需要进行信道测量，获取信道信息。信道测量的主要方法是：网络设备为终端设备配置用于信道测量的资源，然后发送资源给终端设备，终端设备测量这些资源，最后反馈这些资源对应的测量结果给网络设备。
网络侧可以采用不同的传输机制为不同终端设备传输数据。例如对于位于小区中心的终端设备，网络侧可以基于单个传输站点(transmission and reception point，TRP)为其传输数据，而对于位于小区边缘的终端设备，则可以基于多个TRP向其传输数据。基于多个TRP传输数据称为协同传输(coordinated multiple points，COMP)。在进行协同传输时，也需要进行信道测量。以两个TRP协同传输为例，终端设备测量的信道是两个TRP的联合信道，例如如图3所示。终端设备需要测量两个TRP发送的参考信号，从而确定两个TRP组成的联合信道的信道质量。
目前，网络设备可以为终端设备配置一个信道资源，该信道资源包括多个端口资源。网络设备通过多个TRP分别发送端口资源，终端设备在接收到各个TRP发送的端口资源后，通过测量各个TRP上传输的信号，从而可以实现多TRP联合测量。但是在高频传输场景中，数据传输需要采用特定的波束来进行传输，多个TRP在协同传输数据时，不同TRP采用的发送波束可能不同，因此，终端设备在对多个TRP进行联合信道测量时，多个TRP发送信号时所采用的波束可能不同。然而，一个信道资源中只能配置一个波束信息，因此，目前的联合信道测量方法无法应用于高频信道测量。
基于此，本申请实施例提供一种信道测量方法及装置，可以实现高频信道测量。其中，方法和装置是基于同一发明构思的，由于方法及装置解决问题的原理相似，因此装置与方法的实施可以相互参见，重复之处不再赘述。
本申请实施例中涉及的资源集合可以是指resource set，也可以是指resource setting和resource configruation。
本申请实施例中，信道资源与干扰资源具有相同的接收波束，可以理解为信道资源与干扰资源对应的接收波束的方向相同，也可以指信道资源与干扰资源具有typeD的准同位关系，还可以指信道资源与干扰资源采用相同的TCI-state。
本申请实施例中，测量类型也可以称为测量模式，测量类型至少可以包括单独测量和联合测量两种类型。其中，单独测量可以理解为分别测量各个测量资源，并得到各个测量资源分别对应的信道信息。单独测量也可以称为独立测量、信道单独测量、单独信道测量、独立信道测量、信道独立测量等等。联合测量可以理解为将多个测量资源联合起来进行测量，得到联合信道信息。单独测量也可以称为信道联合测量联合信道测量等等。应理解，单独测量、联合测量仅是一种示例性命名，并不对测量类型的命名进行具体限定。为了描述上的方便，下面将分别测量各个测量资源，并得到各个测量资源分别对应的信道信息的测量类型统一称为单独测量，将多个测量资源联合起来进行测量，得到联合信道信息的测 量类型统一称为联合测量。
本申请实施例中，具有/采用相同TCI-state，可以理解为具有/采用相同的接收波束，或相同的QCL假设(如typeD类型的QCL假设)，或可以理解为采用的TCI-state的索引相同，或者采用的TCI-state中typeD类型的QCL-info包含的参考信号资源相同，还可以理解为具有QCL关系，例如具有类型为typeD的QCL关系。具有/采用不同TCI-state，可以理解为具有不同的接收波束，或具有不同的QCL假设(如typeD类型的QCL假设)，或可以理解为采用的TCI-state的索引不同，或者采用的TCI-state中typeD类型的QCL-info包含的参考信号资源不同，还可以理解为不具有QCL关系，例如不具有类型为typeD的QCL关系。

本申请实施例中，TRP还可以与测量资源或信道资源的port相互替换。例如，一个TRP对应的预编码矩阵/基底/交叉极化的port之间的相位差/panel间相位差，可以理解为该TRP对应的一组port对应的预编码矩阵/基底/交叉极化的port之间的相位差/panel间相位差。

下面结合附图对本申请实施例提供的方法进行具体说明。
实施例一：
参见图4，为本申请提供的一种信道测量方法的流程图，该方法可以应用于通信设备或者芯片或者芯片组等，下面以通信设备为例进行说明，该方法包括：
S401，网络设备向终端发送测量配置信息。相应的，终端设备接收来自网络设备的测量配置信息。其中，测量配置信息用于配置一组或多组测量资源，每组测量资源包括多个测量资源，且每组测量资源用于进行一次联合信道测量。需要说明的是，测量配置信息配置的多组测量资源中，每组测量资源所包括测量资源的数量可以相等，也可以不相等，这里不做具体限定。此外，若测量配置信息配置多组测量资源，可以存在一组测量资源所包括测量资源的数量为1。
示例性的，测量资源可以是用于测量信道的信道资源，信道资源也可以称为信道测量资源。或者，测量资源也可以是用于测量干扰的干扰资源，干扰资源也可以称为干扰测量资源。信道资源的类型可以是NZP CSI-RS资源、SSB资源、CSI-IM资源、零功率信道状态信息参考信号(Zero-Power Channel Status Information Reference Signal，ZP CSI-RS)资 源中的任意一种或多种的组合。干扰资源的类型可以是NZP CSI-RS资源、SSB资源、CSI-IM资源、ZP CSI-RS资源中的任意一种或多种的组合。
一种举例说明中，测量配置信息可以包括测量配置，其中，测量配置包括测量资源的相关配置信息，例如，测量配置用于配置上述一组或多组测量资源。示例性的，测量配置中还可以包括发送周期，时频资源位置，端口数等相关参数。
可选的，测量配置信息还可以包括上报配置。
一种可能的实施方式中，针对一组测量资源，测量配置信息还用于指示该组测量资源包括的测量资源是否是用于联合信道测量的。通过上述实施方式，当网络设备为终端设备配置多个测量资源时，终端设备可以确定这些测量资源是用于单独测量的，还是用于联合测量。
一种具体实现方式中，可以是测量配置信息中的测量配置来指示该组测量资源包括的测量资源是否是用于联合信道测量的。
在一些实施例中，测量配置信息可以通过如下六种方式中的一种或多种来指示一组测量资源包括的测量资源是否是用于联合信道测量的。
方式一，测量配置信息可以通过配置第一参数指示测量资源的测量类型，测量类型至少有联合测量和单独测量两种。若测量类型为联合测量，则表示一组测量资源包括的测量资源是用于联合信道测量的，若测量类型为单独测量，则表示一组测量资源包括的测量资源不是用于联合信道测量的。其中，第一参数可以包括一个或多个参数，这里不做具体限定。以第一参数为groupBasedBeamReporting参数为例进行举例说明，测量配置信息可以采用groupBasedBeamReporting参数来进行指示测量类型，例如，当groupBasedBeamReporting参数的值配置成enabled时可以表示采用联合测量。当groupBasedBeamReporting参数的值配置成disabled时可以表示采用单独测量。
进一步的，可以在测量配置信息指示测量CQI/RI/PMI等参数中的一种或多种时，通过方式一来指示该组测量资源包括的测量资源是用于联合信道测量的，例如，若测量配置信息指示测量CQI/RI/PMI等参数中的一种或多种，groupBasedBeamReporting参数可以用于指示测量类型。
方式二，测量配置信息可以通过配置第二参数指示用于信道联合测量的测量资源的数量，其中，当第二参数配置成大于1(即用于信道联合测量的测量资源的数量配置成大于1)的值时，可以表示测量类型为联合测量，否则，可以表示测量类型为单独测量。或者，当测量配置信息配置第二参数时可以表示测量类型为联合测量，不配置时可以表示测量类型为单独测量。
方式三，测量配置信息可以通过一组测量资源包括的测量资源所在资源集合数量来指示该组测量资源包括的测量资源是否用于联合信道测量的。例如，若将一组测量资源包括的多个测量资源配置在多个资源集合中，则可以表示该组测量资源包括的多个测量资源是用于联合信道测量的。若将一组测量资源包括的多个测量资源配置在一个资源集合中，则可以表示测量类型为该组测量资源包括的多个测量资源不是用于联合信道测量的。例如，该组测量资源包括N个测量资源，若该N个测量资源配置在N个资源集合中，则可以表示该N个测量资源是用于联合信道测量的，N为大于1的整数。又例如，该组测量资源包括M个测量资源，若该M个测量资源配置在m个资源集合中，则可以表示该M个测量资源是用于联合信道测量的，M为大于1的整数，m为大于0且小于M的整数。
方式四，测量配置信息可以通过测量资源的配置形式来指示该组测量资源包括的测量资源是否用于联合信道测量的。例如，若将所有测量资源配置在多个资源集合中，则表示每个资源集合内的测量资源可以作为一组测量资源进行联合信道测量。
一种实现方式中，方式四可以与方式一联合指示测量类型，即所有测量资源配置在多个资源集合中，且通过第一参数(如groupBasedBeamReporting)指示测量类型为联合测量时，将每个资源集合内的测量资源可以作为一组测量资源进行联合信道测量。
方式五，测量配置信息可以通过信道资源数量和干扰资源的类型来指示测量类型。例如干扰资源类型为NZP CSI-RS且信道资源数量大于1时，可以表示测量类型为联合测量。
方式六，测量配置信息可以通过码本类型来指示测量类型，若测量类型为联合测量，则表示一组测量资源包括的测量资源是用于联合信道测量的，若测量类型为单独测量，则表示一组测量资源包括的测量资源不是用于联合信道测量的。例如，当码本类型配置为某种特定的类型时，可以指示测量类型为联合测量。
一种示例性说明中，可以将用于联合测量的多个测量资源称为一个测量资源组，即一组测量资源可以称为一个测量资源组。
一种举例说明中，测量资源组可以是一个物理分组，例如测量资源组可以是一个资源集合。网络设备可以为终端设备配置一个或多个资源集合，当进行联合信道测量时，将每个资源集合内的资源联合起来进行测量。可选的，资源集合可以满足如下两个条件中的一个或多个：资源集合的数量可以为K，K为正整数，例如1，2，4，8等；每个资源集合内的测量资源的端口数之和可以不超过H，H为正整数，例如4，8，12，16，18，24，32，64等。网络设备配置的资源集合也可以不全部用于联合测量，例如有的资源集合内的资源用于联合测量，有的资源集合内的资源用于单独测量，网络设备可以指示哪些资源集合用于联合测量。例如，通过一个或多个参数来指示某个资源集合是用于联合测量还是单独测量。
K、H的值可以通过RRC/媒体接入控制控制单元(medium access control control element，MAC CE)/DCI信令来指示，也可以通过UE能力上报过程来上报，也可以是协议规定的。如果是RRC配置的，K、H可以是必选的参数，也可以是可选的参数。K、H未配置时，K、H可以取默认值，例如，默认值可以是2,3,4,5,6,7,8,12,16中的一个。
一种举例说明中，K、H的值/上限值可以但不限于是1,2,3,4,5,6,7,8,12,16中的任意一个。一种举例说明中，K、H的取值范围可以是{1,2,3,4,5,6,7,8,12,16}或其子集。
需要说明的是，K和H的取值范围可以相同，也可以不同，上述取值、取值范围仅是一种示例性说明，并不对K和H的取值范围进行具体限定。
另一种举例说明中，测量资源组也可以是一个逻辑分组，即不显示配置测量资源组。例如，可以将所有测量资源配置在一个资源集合中，按照各个测量资源配置的顺序或测量资源的索引大小顺序，每N个测量资源作为一个测量资源组。例如，配置了6个测量资源{#2，#3，#4，#6，#1，#7}，每两个测量资源作为一个测量资源组，因此{#2，#3}可以作为一个测量资源组，{#4，#6}可以作为一个测量资源组，{#1，#7}可以作为一个测量资源组。又例如，配置了9个测量资源{#1，#2，#3，#4，#5，#6，#7，#8，#9}，每三个测量资源作为一个测量资源组，因此{#1，#4，#7}可以作为一个测量资源组，{#2，#5，#8}可以作为一个测量资源组，{#3，#6，#9}可以作为一个测量资源组。本申请实施例不对测量资源组的分组方式进行具体限定。
一个测量资源组中的测量资源可以是同一个小区的资源，也可以是不同小区的测量资源，这里不做具体限定。
目前，由于typeII码本复杂度较高，协议规定：若上报的码本为类型2(typeII)码本，测量资源的数量只能配置为1。而本申请实施例中，在采用typeII码本上报时，可以配置多个测量资源。例如，当测量类型为单独测量时，如果上报的码本类型是typeII码本，测量配置信息中只能配置单个测量资源；当测量类型是联合测量时，如果上报的码本类型是typeII码本，测量配置信息中可以配置多个测量资源。
一种实现方式中，若测量类型是联合测量，且上报的码本类型是typeII码本，测量配置信息中可以配置一个测量资源组。示例性的，该测量资源组可以满足如下三个条件中一个或多个：
条件一，测量资源的数量不超过L，L为正整数，例如2，4，8等。
条件二，每个测量资源的端口数可以不超过S，P为正整数，例如1，2，4，8，16等。
条件三，所有测量资源的端口数之和不超过F，M为正整数，例如2，4，8，12，16，18，24，32，64等。
L、S、F的值可以通过RRC/MAC CE/DCI信令来指示，也可以通过UE能力上报过程来上报，也可以是协议规定的。如果是RRC配置的，L、S、F可以是必选的参数，也可以是可选的参数。L、S、F未配置时，L、S、F可以取默认值，例如，默认值可以是2,3,4,5,6,7,8,12,16中的一个。
一种举例说明中，L、S、F的值/上限值可以但不限于是1,2,3,4,5,6,7,8,12,16中的任意一个。一种举例说明中，L、S、F的取值范围可以是{1,2,3,4,5,6,7,8,12,16}或其子集。
需要说明的是，L、S、F的取值范围可以相同，也可以不同，上述取值、取值范围仅是一种示例性说明，并不对L、S、F的取值范围进行具体限定。
目前，协议规定一个资源集合中的测量资源的频域密度是相等的，且端口数是相等的。而本申请实施例中，一个资源集合测量中的测量资源的频域密度可以相等也可以不相等，端口数可以相等也可以不相等。例如，当测量类型是单独测量时，一个资源集合内的测量资源的频域密度是相等的，且端口数是相等的；当测量类型是联合测量时，一个资源集合内的测量资源的频域密度可以相等也可以不相等，端口数可以相等也可以不相等。
在一些实施例中，测量资源为信道资源。测量配置信息还用于配置干扰资源。
一种示例性说明中，干扰资源可以包括一个或多个CSI-IM资源，进行信道联合测量时，一个CSI-IM资源可以与一组测量资源相关联。例如，以测量资源组是一个资源集合为例，一个CSI-IM资源可以关联一个资源集合，CSI-IM资源数量可以等于资源集合数。又例如，以测量资源组是一个逻辑分组为例，若一个测量资源组包括N个测量资源，测量资源与CSI-IM资源可以满足N:1的数量关系，即每N个测量资源可以关联一个CSI-IM资源。
CSI-IM资源与关联的测量资源具有相同的QCL关系，因此终端设备可以采用CSI-IM资源关联的测量资源组内的测量资源的TCI-state或QCL信息来确定该CSI-IM的TCI-state或QCL信息，即采用这些测量资源的接收波束来接收该CSI-IM资源并进行测量。例如，CSI-IM资源#1和测量资源{#2，#3}是关联的，那么终端设备可以采用测量资源#2和测量资源#3的接收波束来接收CSI-IM资源#1。
另一种示例性说明中，干扰资源还可以包括一个或多个NZP CSI-RS资源，进行信道 联合测量时，一组测量资源与至少一个NZP CSI-RS资源相关联，与同一组测量资源关联的该至少一个NZP CSI-RS资源可以称为一个干扰资源组。一个干扰资源组可以是一个资源集合。
与同一组测量资源关联的该至少一个NZP CSI-RS资源与关联的测量资源具有相同的QCL关系。从而，终端设备可以采用测量资源组内测量资源的TCI-state或QCL信息来确定关联的各个NZP CSI-RS资源的TCI-state或QCL信息，即采用这些测量资源的接收波束来接收关联的NZP CSI-RS资源并进行测量。终端设备可以将关联的每个NZP CSI-RS干扰资源作为一个干扰层，通过将所有干扰层对应的能量加起来计算对应的测量资源的干扰。
目前，协议规定：当干扰资源类型为NZP CSI-RS时，信道资源的数量为1。而本申请实施例中，当干扰资源类型为NZP CSI-RS时，信道资源的数量可以大于1。例如，当测量类型是单独测量时，如果配置了类型为NZP CSI-RS的干扰资源，测量配置信息配置单个信道资源；当测量类型是联合测量时，如果配置了类型为NZP CSI-RS的干扰资源，测量配置信息中可以配置多个信道资源。
一种实现方式中，当测量类型是联合测量时，如果配置了类型为NZP CSI-RS的干扰资源，测量配置信息中可以配置一组信道资源。可选的，该组信道资源可以满足如下条件中至少一项：该组信道资源中信道资源的数量不超过Q，Q为正整数，例如2，4，8等；每个信道资源的端口数不超过Y，Y为正整数，例如1，2，4，8，16等；所有信道资源的端口数之和不超过Z，Z为正整数，例如2，4，8，12，16，18，24，32，64等。
Q、Y、Z的值可以通过RRC/MAC CE/DCI信令来指示，也可以通过UE能力上报过程来上报，也可以是协议规定的。如果是RRC配置的，Q、Y、Z可以是必选的参数，也可以是可选的参数。Q、Y、Z未配置时，Q、Y、Z可以取默认值，例如，默认值可以是2,3,4,5,6,7,8,12,16中的一个。
一种举例说明中，Q、Y、Z的值/上限值可以但不限于是1,2,3,4,5,6,7,8,12,16中的任意一个。一种举例说明中，Q、Y、Z的取值范围可以是{1,2,3,4,5,6,7,8,12,16}或其子集。
需要说明的是，Q、Y、Z的取值范围可以相同，也可以不同，上述取值、取值范围仅是一种示例性说明，并不对Q、Y、Z的取值范围进行具体限定。
S402，网络设备基于测量配置信息发送测量资源对应的参考信号。其中，一个测量资源可以对应一个参考信号。
S403，终端设备基于测量配置信息进行联合信道测量。
一种实现方式中，针对每组测量资源，终端设备可以确定该组测量资源中每个测量资源对应的信道，然后根据该组测量资源中每个测量资源对应的信道联合确定预编码矩阵。
在一些实施例中，终端设备可以有多种联合测量方式，例如，多种联合测量方式至少可以包括如下两种方式：
联合测量方式一，基于每组测量资源包括的多个测量资源确定一个预编码矩阵。下面以每组测量资源包括X个测量资源为例进行说明，联合测量方式一可以为联合X个测量资源，确定1个PMI，该PMI的端口数可以等于X个测量资源的端口数之和。该PMI是联合计算出来的。例如，假设X＝2时，两个测量资源对应的信道为H1和H2，终端设备可以确定一个W，使得满足[H1,H2]W的能量最大。终端设备可以向网络设备上报该PMI。
一种示例性说明中，还可以基于该PMI确定1个RI，该RI表示该PMI所采用的流数 (rank)。终端设备可以向网络设备上报该RI。
一种示例性说明中，还可以基于该组测量资源确定一个CQI，该CQI是根据各个测量资源联合测得的CQI，表示各个测量资源组成的联合信道的信道质量。终端设备可以向网络设备上报该CQI。
此外，终端设备还可以上报LI给网络设备，用于指示RI指示的多流中的一流，如最好的那一流。终端设备还可以所有测量资源对应的i1信息给网络设备，i1可以包括PMI信息中的全带信息。
联合测量方式二，基于每组测量资源包括的多个测量资源确定多个预编码矩阵，其中，该多个测量资源与该多个预编码矩阵一一对应。下面以每组测量资源包括X个测量资源为例进行说明，联合测量方式二可以为联合测量X个测量资源，确定X个PMI，每个PMI对应一个测量资源。其中，PMI的端口数等于对应的测量资源的端口数。这X个PMI是联合计算出来的。例如，假设X＝2时，两个测量资源对应的信道为H1和H2，终端设备可以确定两个W，即W1和W2，使得满足[H1W1,H2W2]的能量最大。终端设备可以向网络设备上报该X个PMI。
示例性的，还可以基于X个PMI确定1个RI，该RI与X个PMI对应。终端设备可以向网络设备上报该RI。或者，还可以基于X个PMI确定X个RI，一个RI与一个PMI对应。终端设备可以向网络设备上报该X个RI。
示例性的，还可以基于每组测量资源确定一个CQI，该CQI与X个PMI对应，即是X个测量资源计算出来的联合CQI，表示各个测量资源组成的联合信道的信道质量。终端设备可以向网络设备上报该CQI。或者，还可以基于每组测量资源确定X个CQI，一个CQI与一个PMI对应。
一些实施例中，在联合测量中，在测量一个信道资源时，终端设备可以将其他信道资源作为干扰资源。
此外，终端设备也可以上报多个LI给网络设备，每个LI与一个RI或PMI对应，表示上报的RI或PMI对应的多流中的一流，如最强的那一流。终端设备也可以上报多个i1给网络设备，每个i1对应一个测量资源，i1包括PMI信息中的全带信息。
除了上述两种联合测量方式，还可以采用其他联合测量方式，本申请实施例不做限定。
当协议只支持一种联合测量方式时，可以在测量配置信息指示一组测量资源包括的测量资源是用于联合信道测量的时，采用该联合测量方式进行联合信道测量。
当协议支持多种联合测量方式时，例如支持上述两种联合测量方式时，测量配置信息还可以指示具体采用哪种联合测量方式。例如，测量配置信息可以通过一个或多个参数指示具体采用哪种联合测量方式。又例如，可以配置一个用于指示测量类型/码本类型/测量模式的参数，该参数可以有多个可选值，每个值表示一种联合测量方式。当该参数未配置时可以表示不采用联合测量。该参数还可以有一个可选值表示单独测量，当该参数配置成该可选值时可以表示不采用联合测量。或者，测量配置信息还可以通过上报的上报量来指示采用哪种联合测量方式，例如上述两种联合测量方式对应了不同的上报量选项，通过配置的上报量，终端设备可以确定是否采用联合测量，或者确定采用哪种联合测量方式。
示例性的，终端设备具体采用哪种联合测量方式，也可以是终端设备确定。
示例性的，该多种联合测量方式可以是网络设备配置给终端设备的，也可以是终端设备预配置的。可选的，终端设备可以通过能力上报参数上报是否支持联合测量，或者上报 具体支持哪种联合测量方式。
PMI是预编码矩阵的标识，上报PMI的实质是向网络设备告知一个预编码矩阵，让网络设备采用该预编码矩阵进行数据传输。为了降低上报开销，目前协议中定义了一些预编码矩阵的集合，终端设备只需要上报这些集合内的预编码矩阵即可。这些预定义好的预编码矩阵也被称为码本。目前协议中有四种不同的码本集合或码本类型:Type I single-panel码本；Type I multi-panel码本；TypeII码本；typeII Port selection码本。
其中，Type I single-panel码本：
码本实质是一个矩阵，行数等于天线端口数(CSI-RS端口数)，列数等于rank或layer数(数据传输的流数)，每一列对应的是一个layer的预编码矩阵。以Rank＝1，测量资源为CSI-IS为例，对应的码本格式为列数为1的矩阵。
Figure PCTCN2021096796-appb-000003
其中P CSI-RS是CSI-RS端口数，用于对预编码矩阵进行归一化。v l,m是一个列向量，表示其中一半CSI-RS port对应的预编码矩阵，另外一半的CSI-RS port对应的预编码矩阵为
Figure PCTCN2021096796-appb-000004
等于在v l,m的基础上乘以
Figure PCTCN2021096796-appb-000005
用于对两个预编码矩阵进行一定的相位补偿。这样做是因为基站天线一般采用交叉极化，即有一半的天线对应一个极化方向，另外一般对应另一个极化方向，两组天线对应的预编码之间存在固定相位差。两组天线对应的预编码矩阵的基底v l,m相同，只不过相差一个相位差
Figure PCTCN2021096796-appb-000006
Rank＝2时，预编码矩阵为列数为2的矩阵，格式如下：
Figure PCTCN2021096796-appb-000007
Rank＝2的预编码矩阵相比于Rank＝1的预编码矩阵多了一列，该列的构成方式与第一列类似，不同的是采用了另外一个基底v l′,m′。
更高RANK的码本可以以此类推，原理就是增加新的列，每一列里面都将CSI-RS端口分成两组，每组采用相同基底，两组之间相差一个相位差。
对于，Type Isingle-panel码本，可以上报基底相关的参数l和m，用于网络设备确定基底v l,m。l和m又可以被表示为i 1,1,i 1,2。网络设备知道l和m的值之后可以采用以下公式计算出v l,m。其中N 1和N 2是水平和垂直CSI-RS端口数，O 1和O 2是水平和垂直过采样倍数。
Figure PCTCN2021096796-appb-000008
还可以上报i 1,3,通过i 1,3查表可以确定k 1和k 2，通过l’＝i 1,1+k 1和m’＝i 1,2+k 2可以确定l’和m’的值，从而确定基底v l′,m′，根据l’和m’计算v l′,m′采用的公式同上。
还可以上报参数n，用于确定交叉极化天线之间的预编码矩阵的相位差
Figure PCTCN2021096796-appb-000009
n又被表示为i 2。
Figure PCTCN2021096796-appb-000010
也就是说，终端设备需要上报参数i 1,1，i 1,2，i 1,3和i 2的值，网络设备通过这些值按照上述方法即可计算出相应的预编码矩阵。
Type I multi-panel码本：
Type I Multi-panel码本比Type I single-panel码本细一些，需要区分不同的天线面板(panel)。以Rank＝1，panel数等于2为例，对应的码本格式为列数为1的矩阵。
Figure PCTCN2021096796-appb-000011
上述码本由于是两panel的码本。因此比single-panel的码本的维度多了一倍，其中前两项对应的是第一个panel的预编码矩阵，原理同single-panel码本。后两项对应第二个panel的预编码矩阵，后两项的实质是在前两项基础上乘以一个相位差
Figure PCTCN2021096796-appb-000012
用于补偿两个天线面板间距带来的相位差。也就是说，multi-panel码本实质上是single-panel码本的扩展，有P个panel，就将single-panel码本扩展成P组，每组对应一个panel，每个panel对应的那组相对于第一组要乘以一个相位偏移，用于补偿该panel相对于第一个panel的间距导致的信号相位差。
除了上述参数i 1,1，i 1,2，i 1,3和i 2，终端设备还可以上报不同panel之间的相位差
Figure PCTCN2021096796-appb-000013
对应的参数i 1,4。如果总共只有两个panel，i 1,4只有单个值，用于计算两个panel之间的相位差
Figure PCTCN2021096796-appb-000014
如果panel为4，那么需要确定后三个panel相对于第一个panel的预编码矩阵的相位差
Figure PCTCN2021096796-appb-000015
和
Figure PCTCN2021096796-appb-000016
这时i 1,4包括三个值i 1,4＝[i 1,4,1,i 1,4,2,i 1,4,3]。
Figure PCTCN2021096796-appb-000017
也就是说，终端设备可以上报参数i 1,1，i 1,2，i 1,3，i 1,4和i 2的值，网络设备通过这些值按照上述方法即可计算出相应的预编码矩阵。
type I码本比较简单，反馈的开销小，但精度较差，量化误差较大；type II码本比较复杂，反馈开销较大，但精度高，量化误差小。Type I码本有两种类型：single-panel和multi-panel。Single-panel类型的码本用于单个TRP采用单个天线面板传输的情形；Multi-panel类型的码本用于单个TRP采用多个面板传输的情形。两种类型都适用于单个TRP传输，而不适用于多个TRP传输。也就是说，目前type I的码本并没有专门适配多TRP传输。因此，当终端设备联合测量多个TRP的信道时，其上报给网络设备的码本(不论是Single-panel码本还是multi-panel码本)是不准的，导致数据传输性能受损。
基于此，本申请实施例提供一种码本类型，该码本类型可以适用于多TRP联合测量。为了描述上的方便，下面将适用于多TRP联合测量的该码本类型称为多TRP码本，应理解，这里仅是一种示例性命名，并不对码本的名称进行具体限定。多TRP码本可以包括每组测量资源中每个测量资源对应的参数集合，以及任意两个测量资源之间的相位差。
在Type I multi-panel码本中，多个码本采用相同的基底，因此只需要上报一组i 1,1，i 1,2参数值。采用相同的基底是因为同一个TPR的不同天线面板是平行放置的，即多个panel与信道特征方向的夹角是相同的，因此可以采用相同基底。然而，在多TRP联合信道测量中，由于多个TRP的panel不一定平行，因此不能直接采用相同基底。也就是说每个TRP应该独立采用自己的基底。也就是说，多TRP码本可以为每个TRP独立确定一个基底，基于该基底生成每个TRP对应的预编码矩阵，再将各个TRP对应的预编码矩阵联合起来，组成多TRP码本。每个TRP对应的码本等于该TRP的port数。
一种实施方式中，假设要确定T个TRP对应的联合码本，每个TRP有P个panel。每个TRP对应一个基底，例如TRP i对应的基底为
Figure PCTCN2021096796-appb-000018
终端设备需要上报各个TRP对应的l i和m i的值。例如，上报i 1,1和i 1,2，i 1,1和i 1,2都包括多个值，i 1,1＝[i 1,1,1,i 1,1,2,…,i 1,1,T]，i 1,1＝[i 1,2,1,i 1,2,2,…,i 1,2,T]。同理，对于每个TRP需上报一个i 1,3，即需要上报多个i 1,3的值，i 1,3＝[i 1,3,1,i 1,3,2,…,i 1,3,T]。
对于每个TRP，其交叉极化的天线之间存在一个相位差，例如TRP i对应的交叉极化相位差为
Figure PCTCN2021096796-appb-000019
终端设备需要上报各个TRP对应的n i的值。例如，上报i 2，i 2包括多个值，i 2＝[i 2,1,i 2,2,…,i 2,T]。或者，不同TRP对应的
Figure PCTCN2021096796-appb-000020
也可以是相同的，这时终端设备只需要上报单个n i值，即i 2只有单个值。
当一个TRP有多个panel时，在不同panel上，交叉极化天线之间的相位差可以是不同的，这时对于每个TRP，终端设备需要上报多个交叉极化相位差为

对于每个TRP，其多个panel之间存在一个相位差，例如TRP i对应的panel间相位差为

在一些实施例中，终端设备可以通过一个比特位图来配置每个基底是否可以采用，例如，如果某个基底不能采用，则终端设备不能基于该基底生成的码本。
示例性的，以测量资源为信道资源为例，当进行多TRP联合码本的测量时，终端设备可以采用多个比特位图来分别配置各个TRP可以采用哪些基底。例如，可以通过T个信道资源进行信道联合测量时，每个信道资源对应一个比特位图。每个比特位图的长度可以等于该信道资源对应的基底数N1*O1*N2*O2，其中N1，N2为该信道资源的水平和垂直端口数，O1和O2为该信道资源的水平和垂直过采样倍数。

一种示例性说明中，可以将多TRP码本作为一种新的码本类型。或者，也可以将多TRP码本作为typeI码本类型的一个子类型，例如typeI-multiTRP或typeI-multiRS类型。或者，也可以将上述多TRP码本作为typeI-multiPanel码本类型的一个子类型。
S404，终端设备向网络设备上报测量结果。
一种实现方式中，终端设备可以通过上行信道，如PUCCH/PUSCH上报测量结果。
测量配置分为资源配置和上报配置。每个上报配置关联一个或多个资源配置，终端设备可以根据这些资源配置进行测量，并根据上报配置进行上报。例如，根据上报配置中的PUCCH资源进行上报。当多个上报配置对应的PUCCH相同时，终端设备可以通过该PUCCH上报多个上报配置对应的测量结果。例如，如表2所示，假设PUCCH/PUSCH中需要携带N rep个上报配置对应的测量结果，可以按照表2的优先级对要上报的内容进行优先级(priority)排序。其中，优先级最高的(priority 0)可以是所有上报配置对应的宽带测量结果，如宽带PMI。对于子带(subband)测量结果，可以按照上报配置的编号从小到大的顺序依次降低优先级。对于同一个上报配置可以进一步分成两级优先级，例如，编号为偶数的子带对应的子带测量结果优先级高于编号为奇数的子带对应的子带测量结果。
