背景技术
在高频通信***中，为了克服路损，网络和终端通常都会使用具有方向性的高增益的天线阵列形成模拟波束来进行通信。一般来说，模拟波束是具有方向性的，可以用主瓣方向和3dB波束宽度来描述一个模拟波束形状(beam pattern)。其中，波束宽度越窄，天线增益越大。基于模拟波束，网络设备和终端设备可以朝向特定的方向发送信号和接收信号。以下行通信为例，网络设备朝向特定方向发送信号，终端设备朝向该特定方向接收信号，当发送信号的方向和接收信号的方向对齐时，该网络设备和该终端设备可实现正常通信。为了实现波束对齐(即发送端和接收端的波束方向对齐)，需要进行波束训练。
在现有协议中，下行波束训练是通过网络设备发送一个或多个参考信号，终端设备对网络设备发送的参考信号进行测量，并按要求将测量结果上报来实现的。下行波束训练可以完成波束选择，波束质量测量和上报，波束跟踪等功能。下行波束训练的结果可以用于网络设备进行波束指示。
3GPP Release 16(R16)中，为了实现基于L1(layer 1，层一，即物理层)-SINR(后文中简写为SINR)的波束训练，支持网络设备配置一个或多个用于信号测量的参考信号资源集合(channel measurement resource set，CMR set)，与一个或多个用于干扰测量的参考信号资源集合(interference measurement resource set，IMR set)。并且，CMR set中的参考信号资源(CMR)与IMR set中的参考信号资源(IMR)是一对一对应的。例如，CMR1对应IMR1，CMR2对应IMR2。这样的资源对应方式，可能会增加资源的开销。

在一种可能的实现中，第二资源的周期为第一资源的周期的1/N倍。在该可能的实现方式中，网络设备在一个第一资源的周期内发送N次第二资源的参考信号。通过设置第二资源的周期为第一资源的周期的1/N倍，有利于降低测量结果上报周期的时长，有利于提升波束训练的速度。
在一种可能的实现中，第二资源的周期与第一资源的周期相同，测量N个第二信号强度的时域范围小于或等于一个时间单元的时间长度。可选的，一个时间单元为一个OFDM符号。或者，一个时间单元也可以为两个OFDM符号、三个OFDM符号或四个OFDM符号等。或者，时间单元也可以为一个时隙，一个子帧，一毫秒等。或者，时间单元也可以为两个时隙，两个子帧，两毫秒等。通过实施该可能的实现方式，有利于降低测量结果上报周期的时长，有利于提升波束训练的速度。
在一种可能的实现中，N个第一资源的接收参数相同时，也可以对第二资源上的信号强度进行一次测量，得到一个第二信号强度。向网络设备上报的第一SINR为基于N个第一信号强度和一个第二信号强度得到的N个SINR中的SINR。

具体实施方式
为了使本申请的目的、技术方案和优点更加清楚，下面将结合附图对本申请作进一步地详细描述。
本申请的说明书、权利要求书及附图中的术语“第一”和“第二”等是用于区别不同对象，而不是用于描述特定顺序。此外，术语“包括”和“具有”以及它们任何变形，意图在于覆盖不排他的包含。例如包含了一系列步骤或单元的过程、方法、***、产品或设备没有限定于已列出的步骤或单元，而是可选地还包括没有列出的步骤或单元，或可选地还包括对于这些过程、方法、产品或设备固有的其它步骤或单元。
在本文中提及“实施例”意味着，结合实施例描述的特定特征、结构或特性可以包含在本申请的至少一个实施例中。在说明书中的各个位置出现该短语并不一定均是指相同的实施例，也不是与其它实施例互斥的独立的或备选的实施例。本领域技术人员显式地和隐式地理解的是，本文所描述的实施例可以与其它实施例相结合。
在本申请中，“至少一个(项)”是指一个或者多个，“多个”是指两个或两个以上，“至少两个(项)”是指两个或三个及三个以上，“和/或”，用于描述对应对象的对应关系，表示可以存在三种关系，例如，“A和/或B”可以表示：只存在A，只存在B以及同时存在A和B三种情况，其中A，B可以是单数或者复数。字符“/”一般表示前后对应对象是一种“或”的关系。“以下至少一项(个)”或其类似表达，是指这些项中的任意组合，包括单项(个)或复数项(个)的任意组合。例如，a，b或c中的至少一项(个)，可以表示：a，b，c，“a和b”，“a和c”，“b和c”，或“a和b和c”，其中a，b，c可以是单个，也可以是多个。
3GPP R16引入了基于L1-SINR(layer 1-SINR，层一信干噪比)的波束管理机制，为了进行基于L1-SINR的波束管理，协议允许专门配置干扰测量资源(Interference measurement resource，IMR)。IMR与信道测量资源(Channel measurement resource，CMR)具有一一对应关系，即一个CMR配置一个IMR。IMR资源用于终端设备测量进行干扰和噪声的测量。CMR资源用于终端设备进行信道测量。IMR资源和CMR资源可以统称为CSI-RS资源。
下面对现有的用于波束训练的参考信号测量与上报的相关配置进行详细介绍：
例如，如图1所示，网络设备配置一个上报设置(ReportConfig#1)的上报量是CRI-SINR，且该上报设置(ReportConfig#1)对应两个资源设置(ResourceConfig)，分别为信道测量资源设置(ResourceConfig#1)和干扰测量资源设置(ResourceConfig#2)。信道测量资源设置，其功能标记为信道测量(resourcesForChannelMeasurement)。干扰测量资源设置，其功能标记为干扰测量(resourcesForInterferenceMeasurement)。
RsourceConfig#1中包含一个资源集合列表(ResourceSetList)，其中，该资源集合列表包括M(>＝1)个资源集合。例如，包括资源集合#1(resourceset#1)等。RsourceConfig#2中也包含一个资源集合列表(ResourceSetList)，其中，该资源集合列表包括有M(>＝1)个资源集合，例如资源集合#2(resourceset#2)等。资源集合#1(resourceset#1)中包括Y(>＝1)个CMR资源。例如，图1以资源集合#1包括CSI-RS资源#1(CSI-RS resource#1)和CSI-RS资源#2(CSI-RS resource#2)为例。资源集合#2中包括Y(>＝1)个IMR资源。例如，图1以资源集合#2(resourceset#2)包括CSI-RS资源#11(CSI-RS resource#11)和CSI-RS资源#12(CSI-RS resource#12)为例。其中，CSI-RS resource#1对应CSI-RS  resource#11，CSI-RS resource#2对应CSI-RS resource#12。
然而，图1所示的资源配置可能会增加CMR资源的开销。例如，如图2所示，假设CSI-RS resource#1和CSI-RS resource#2对应的发送参数相同，CSI-RS resource#1和CSI-RS resource#2对应的发送参数均为波束a1。CSI-RS resource#1和CSI-RS resource#2对应的接收参数也相同，CSI-RS resource#1和CSI-RS resource#2对应的接收参数均为波束b1。CSI-RS resource#11对应的发送参数为波束a2，CSI-RS resource#12对应的发送参数为波束a3。
网络设备在CSI-RS resource#1采用波束a1发送参考信号CSI-RS1，在CSI-RS resource#11采用波束a2发送参考信号CSI-RS11。终端设备通过波束b1测量CSI-RS1的信号强度1，以及通过波束b1测量CSI-RS11的信号强度2。终端设备将信号强度1与信号强度2的比值确定为SINR1，并向网络设备上报SINR1。然后网络设备在CSI-RS resource#2采用波束a1发送参考信号CSI-RS2，在CSI-RS resource#12采用波束a3发送参考信号CSI-RS12。终端设备通过波束b1测量CSI-RS2的信号强度3，以及通过波束b1测量CSI-RS12的信号强度4。终端设备将信号强度3与信号强度4的比值确定为SINR2，并向网络设备上报SINR2。
也就是说，图1的资源配置用于测量波束a2和波束a3对同一对波束(波束a1和波束b1)的干扰情况。在这种情况下，终端设备实际上只需要进行一次信道测量，即只需要配置一个CMR资源对应多个IMR资源。例如，在资源集合#1(resourceset#1)中包括CSI-RS resource#1，在资源集合#2(resourceset#2)中包括CSI-RS resource#11和CSI-RS resource#12。这样CSI-RS resource#1就可同时对应CSI-RS resource#11和CSI-RS resource#12。但由于协议规定CMR资源与IMR资源必须一一对应，不能一个CMR资源同时对应多个IMR资源。因此，在现有的CMR资源与IMR资源的对应关系中，在测量多个波束对同一对波束的干扰情况时，通常是对不同的IMR配置不同的CMR资源。可见，这样增加了CMR资源的开销。
因此，为了降低CMR资源的开销，本申请实施例提供了一种信息上报方法。为了能够更好地理解本申请实施例，下面先对本申请实施例的***架构进行说明：
本申请实施例提供的方法可以应用于各类通信***中，例如，可以是物联网(internet of things，IoT)***、窄带物联网(narrow band internet of things，NB-IoT)***、长期演进(long term evolution，LTE)***，也可以是第五代(5th-generation，5G)通信***，还可以是LTE与5G混合架构、也可以是5G新无线(new radio，NR)***，以及未来通信发展中出现的新的通信***等。
图3是本申请实施例提供的一种通信***的架构示意图，本申请中的方案可适用于该通信***。该通信***可以包括至少一个网络设备和至少一个终端设备，图3以通信***中包括一个网络设备和一个终端设备为例。如图3所示，网络设备和终端设备之间可以通过波束进行通信。网络设备和终端设备都能够产生多个波束。图3以网络设备可以发送波束a1～波束a3，终端设备的接收波束包括波束b1和波束b2为例。
本申请实施例中所涉及的网络设备，是网络侧的一种用于发射或接收信号的实体，可以用于将收到的空中帧与网络协议(internet protocol，IP)分组进行相互转换，作为终端设备与接入网的其余部分之间的路由器，其中接入网的其余部分可以包括IP网络等。网络设备还可以协调对空中接口的属性管理。例如，网络设备可以是LTE中的演进型基站 (evolutional Node B，eNB或e-NodeB)，还可以是新无线控制器(new radio controller，NR controller)，可以是5G***中的gNode B(gNB)，可以是集中式网元(centralized unit)，可以是新无线基站，可以是射频拉远模块，可以是微基站，可以是中继(relay)，可以是分布式网元(distributed unit)，可以是接收点(transmission reception point，TRP)或传输点(transmission point，TP)或者任何其它无线接入设备，但本申请实施例不限于此。
本申请实施例中涉及的终端设备，是用户侧的一种用于接收或发射信号的实体。终端设备可以是一种向用户提供语音和/或数据连通性的设备，例如，具有无线连接功能的手持式设备、车载设备等。终端设备也可以是连接到无线调制解调器的其他处理设备。终端设备可以与无线接入网(radio access network，RAN)进行通信。终端设备也可以称为无线终端、订户单元(subscriber unit)、订户站(subscriber station)，移动站(mobile station)、移动台(mobile)、远程站(remote station)、接入点(access point)、远程终端(remote terminal)、接入终端(access terminal)、用户终端(user terminal)、用户代理(user agent)、用户设备(user device)、或用户设备(user equipment，UE)等等。终端设备可以是移动终端，如移动电话(或称为“蜂窝”电话)和具有移动终端的计算机，例如，可以是便携式、袖珍式、手持式、计算机内置的或者车载的移动装置，它们与无线接入网交换语言和/或数据。例如，终端设备还可以是个人通信业务(personal communication service，PCS)电话、无绳电话、会话发起协议(session initiation protocol，SIP)话机、无线本地环路(wireless local loop，WLL)站、个人数字助理(personal digital assistant，PDA)、等设备。常见的终端设备例如包括：手机、平板电脑、笔记本电脑、掌上电脑、移动互联网设备(mobile internet device，MID)、可穿戴设备，例如智能手表、智能手环、计步器等，但本申请实施例不限于此。
下面对本申请实施例提供的信息上报方法进一步进行详细描述：
请参见图4，图4是本申请实施例提供的一种信息上报方法的流程示意图。如图4所示，该信息上报方法包括如下步骤401～步骤406。图4所示的方法执行主语可以为网络设备和终端设备，或主语可以为网络设备中的芯片和终端设备中的芯片。图4以网络设备和终端设备为方法的执行主体为例进行说明。本申请实施例的其他附图所示的信息上报方法的执行主语同理，后文不再赘述。其中：
401、网络设备向终端设备发送配置信息。
其中，该配置信息用于配置第一资源集合和第二资源集合，该第一资源集合中的资源标识对应的资源用于信道测量，该第二资源集合中的资源标识对应的资源用于干扰测量，该第一资源集合中包括N个第一资源的标识，该N个第一资源的标识相同，该第二资源集合中包括N个第二资源的标识，该N个第一资源的标识与该N个第二资源的标识一一对应(或关联)，N为大于1的整数。
由于该第一资源集合中包括N个第一资源的标识，且N个第一资源的标识相同。因此，可以理解为该第一资源集合包括N个相同的第一资源，或者，可以理解为该第一资源集合包括一个第一资源。
其中，该第二资源集合中包括的N个第二资源的标识可以相同或不相同。如果该N个第二资源的标识相同，则表示该第二资源集合包括N个相同的第二资源。如果该N个第二资源的标识不相同，则表示该第二资源集合包括N个不相同的第二资源。
举例来说，如图5所示，第一资源集合为资源集合#1(resourceset#1)对应的资源集 合。第二资源集合为资源集合#2(resourceset#2)对应的资源集合。其中，第一资源集合包括两个相同的第一资源的标识，第一资源的标识为CSI-RS resource#1。第二资源集合包括两个第二资源的标识，分别为CSI-RS resource#11和CSI-RS resource#12。第一个CSI-RS resource#1与CSI-RS resource#11相对应，第二个CSI-RS resource#1与CSI-RS resource#12相对应。也就是说，第一资源集合中包括两个相同的第一资源，第二资源集合中包括两个不相同的第二资源。
可选的，配置信息中还包括重复因子。该重复因子为开启时，表示N个第一资源的发送参数为同一个发送参数。该重复因子为关闭时，表示N个第一资源的发送参数不为同一个发送参数。例如，如图5所示，重复因子为repetition，该重复因子为开启。“Repetition：ON”表示重复因子为开启。“Repetition：OFF”表示重复因子为关闭。
402、网络设备在第一资源发送第一参考信号。
403、网络设备在N个第二资源分别发送第二参考信号。
本申请实施例中，网络设备向终端设备发送配置信息之后，网络设备可在第一资源发送第一参考信号以及在N个第二资源分别发送第二参考信号。
404、终端设备测量第一资源上的信号强度，得到第一信号强度。
405、终端设备测量N个第二资源上的信号强度，得到N个第二信号强度。
本申请实施例中，终端设备接收网络设备发送的配置信息之后，可测量第一资源上的第一信号强度，以及测量N个第二资源上的信号强度，得到N个第二信号强度。
在一种可能的实现中，N个第二资源的接收参数与第一资源的接收参数相同。或者，可以表达为：N个第二资源的接收参数与第一资源的接收参数是准共址(quasi-co-location，QCL)的。或者，可以表达为：终端设备通过第一资源的接收参数测量N个第二资源上的信号强度。通过实施该可能的方式，能够准确地测量出第二资源的发送参数对第一资源的发送参数和/或接收参数的干扰情况。
举例来说，以终端设备在一个测量结果上报周期内进行的测量为例进行说明。如图6所示，一个测量结果上报周期为10ms。CSI-RS resource#1的周期为10ms。CSI-RS resource#11的周期为10ms。CSI-RS resource#12的周期为10ms。在一个测量结果上报周期内，终端设备总共进行测量3个参考信号，分别为在CSI-RS resource#1对应的资源发送的CSI-RS1，在CSI-RS resource#11对应的资源发送的CSI-RS11，在CSI-RS resource#12对应的资源发送的CSI-RS12。其中，CSI-RS resource#1的发送参数为波束a1，CSI-RS resource#11的发送参数为波束a2，CSI-RS resource#12的发送参数为波束a3。CSI-RS resource#1的接收参数为波束b1。终端设备通过波束b1在CSI-RS resource#1对应的资源测量CSI-RS1的信号强度，得到第一信号强度P1。终端设备通过波束b1在CSI-RS resource#11对应的资源测量CSI-RS11的信号强度，得到第二信号强度P11。终端设备通过波束b1在CSI-RS resource#12对应的资源测量CSI-RS12的信号强度，得到第二信号强度P12。可见，在一个测量结果上报周期内，终端设备只进行一次信道测量。
在一种可能的实现中，信号强度可以为信号接收功率或信号接收能量等。
406、终端设备基于第一信号强度和N个第二信号强度向网络设备上报第一SINR。
本申请实施例中，终端设备测量得到第一信号强度和N个第二信号强度之后，可基于第一信号强度和N个第二信号强度向网络设备上报第一SINR。
下面对终端设备基于第一信号强度和N个第二信号强度向网络设备上报第一SINR的 两种具体实现方式进行介绍：
方式一：终端设备确定N个SINR，该N个SINR中第i个SINR基于第一信号强度和N个第二信号强度中的第i个第二信号强度得到，i为大于0，且小于或等于N的整数；终端设备向网络设备上报N个SINR中的一个或多个第一SINR。
例如，终端设备测量得到上述第一信号强度P1、第二信号强度P11和第二信号强度P12。终端设备可以确定2个SINR。SINR1＝P1/(P11+N1)。SINR2＝P1/(P12+N2)。其中，N1和N2为噪声功率。N1和N2可以相同或不同。终端设备可以按照协议预定义的或者网络设备配置的波束上报数目来确定上报多少个SINR。例如，如果协议预定义的或者网络设备配置的波束上报数目为2，终端设备可以向网络设备上报SINR1和SINR2。或者，如果协议预定义的或者网络设备配置的波束上报数目为1，终端设备可以向网络设备上报SINR1和SINR2中的最大值或最小值。
通过实施方式一，有利于网络设备确定一个或多个第二资源的发送参数对第一资源的发送参数和/或接收参数的干扰情况。网络设备确定一个或多个第二资源的发送参数对第一资源的发送参数和/或接收参数的干扰情况之后，在后续进行数据传输时，就可以通过调度，规避相互干扰较大的波束同传，或者配对相互干扰较小的波束同传。
可选的，网络设备还可以指示终端设备上报最大的SINR或者最小的SINR。或者，网络设备还可以指示终端设备上报相互干扰较大的波束或者相互干扰较小的波束，例如，指示终端设备上报SINR大于预设阈值或小于预设阈值的SINR。
在一种可能的实现中，终端设备还可向网络设备上报该一个或多个第一SINR对应的第一资源的标识在第一资源集合中的位置。例如，终端设备向网络设备上报SINR1和SINR2，则终端设备向网络设备上报SINR1对应的CSI-RS resource#1在第一资源集合中的位置为第一位，SINR2对应的CSI-RS resource#1在第一资源集合中的位置为第二位。
虽然第一资源集合中第一资源的标识相同，但计算SINR时采用的第二资源不同，因此通过向网络设备上报该一个或多个第一SINR对应的第一资源的标识在第一资源集合中的位置，有利于网络设备准确地确定计算SINR时采用的第二资源。
其中，第一SINR对应的第一资源在第一资源集合中的位置通过X个比特指示，该
Figure PCTCN2019119288-appb-000001
K为第一资源集合中不同的资源标识的数量，该N i为K个资源标识中第i个资源标识重复的次数。
Figure PCTCN2019119288-appb-000002
为第一资源集合中总共包括的标识数量。例如，在图5所示的配置中，K为1。N i为2。因此，
Figure PCTCN2019119288-appb-000003
为2。因此，第一SINR对应的第一资源在第一资源集合中的位置通过1个比特指示。例如，如果比特值为0，表示第一SINR对应的第一资源在第一资源集合中的位置为第一位；如果比特值为1，表示第一SINR对应的第一资源在第一资源集合中的位置为第二位。
方式二：第一SINR基于N个第二信号强度之和以及第一信号强度得到。在方式二中，终端设备基于第一信号强度和N个第二信号强度只得到一个SINR。例如，第一SINR＝＝P1/(P11+P12+N1)。通过实施方式二，可以实现干扰累加的功能。在终端设备经历的干扰环境较为复杂时，可以使干扰测量更加准确。例如，网络设备与目标终端设备通过一个服务波束进行通信时，还与其他终端设备通过其他波束进行通信。目标终端设备会受到多个干扰波束的影响，这时网络设备可以在多个第二资源上模拟多个干扰波束的传输，目标终端设备可以将多个第二资源上测到的干扰进行累加。
按照RAN1的指导，支持option2a(即一个CMR关联多个IMR)不应该有RRC影响， 这意味着基站只能配置一个包含N个CMR的列表和另一个包含N个IMR的列表，并且CMR和IMR是一一对应的。作为一种解决方案，这个包含N个CMR的列表(中的N个CMR)可以被配置成相同的CSI-RS资源标识，这样隐式的通知终端应该采用option2a的方法在计算干扰时将关联的N个IMR的测量结果累加。提议X：通过配置一个列表的CMR资源具有相同的CSI-RS资源ID的方式支持option2a(即一个CMR关联多个IMR)的L1-SINR上报。(Following previous RAN1 guidance,support of option 2a should not have RRC impact,which means that gNB can only configure a list of N CMR(s)and another list of N IMR(s),and they are 1:1 mapped.As a compromised solution,the list of CMR(s)can be configured with the same CSI-RS resource ID,which indicates implicitly that UE should adopt option 2a to calculate the interference based on accumulating measurement of all the associated N IMR(s).Proposal X:Support option 2a(1 CMR can associates with more than 1 IMRs)for L1-SINR report,by configuring a list of CMRs with the same CSI-RS resource ID.)
在一种可能的实现中，如果第一资源集合中所有标识相同，则在方式二中，终端设备可以不向网络设备上报第一资源在第一资源集合中的位置。
在一种可能的实现中，如果第一资源集合中还包括与第一资源的标识不同的资源标识，则在方式二中，终端设备可以向网络设备上报第一资源在第一资源集合中的位置。例如，第一资源在第一资源集合中的位置通过X个比特指示，该
Figure PCTCN2019119288-appb-000004
K为第一资源集合中不同的资源标识的数量。例如，图5中第一资源集合除包括2个CSI-RS resource#1之外，还包括2个CSI-RS resource#2，则K为2，X为1。
在一种可能的实现中，协议预定义或者网络设备可指示终端设备采用上述方式一或方式二来上报第一SINR。
在一种可能的实现中，终端设备可以上报能力信息，该能力信息指示终端设备是否支持图4所对应的实施例所描述的方法。
在一种可能的实现中，协议预定义或者网络设备可指示终端设备执行图4所对应的实施例所描述的方法。
在图4所描述的方法中，网络设备在第一资源集合配置N个相同的第一资源的标识，在第二资源集合配置N个第一资源的标识，该N个第一资源的标识与该N个第二资源的标识一一对应。因此，通过实施图4所描述的方法，有利于节省资源的开销。
上述实施例介绍了如何节省CMR资源的开销，下面结合图7对如何节省IMR资源的开销进行介绍：
请参见图7，图7是本申请实施例提供的另一种信息上报方法的流程示意图。如图7所示，该信息上报方法包括如下步骤701～步骤706。图7所示的方法执行主语可以为网络设备和终端设备，或主语可以为网络设备中的芯片和终端设备中的芯片。图7以网络设备和终端设备为方法的执行主体为例进行说明。本申请实施例的其他附图所示的信息上报方法的执行主语同理，后文不再赘述。其中：
701、网络设备向终端设备发送配置信息。
其中，该配置信息用于配置第一资源集合和第二资源集合，该第一资源集合中的资源标识对应的资源用于信道测量，该第二资源集合中的资源标识对应的资源用于干扰测量，该第一资源集合中包括N个第一资源的标识，该第二资源集合中包括N个第二资源的标识， 该N个第二资源的标识相同，该N个第一资源的标识与N个第二资源的标识一一对应，该N为大于1的整数。
由于该第二资源集合中包括N个第二资源的标识，且N个第二资源的标识相同。因此，可以理解为该第二资源集合包括N个相同的第二资源，或者，可以理解为该第二资源集合包括一个第二资源。
其中，该第一资源集合中包括的N个第一资源的标识可以相同或不相同。如果该N个第一资源的标识相同，则表示该第一资源集合包括N个相同的第一资源。如果该N个第一资源的标识不相同，则表示该第一资源集合包括N个不相同的第一资源。
举例来说，如图8所示，第一资源集合为资源集合#1(resourceset#1)对应的资源集合。第二资源集合为资源集合#2(resourceset#2)对应的资源集合。其中，第一资源集合包括两个第一资源的标识，分别为CSI-RS resource#1和CSI-RS resource#2。第二资源集合包括两个相同的第二资源的标识，该第二资源的标识为CSI-RS resource#11。CSI-RS resource#1与第一个CSI-RS resource#11相对应，CSI-RS resource#2与第二个CSI-RS resource#11相对应。也就是说，第一资源集合中包括两个不相同的第一资源，第二资源集合中包括两个相同的第二资源。
可选的，配置信息中还包括重复因子。该重复因子为开启时，表示N个第一资源的发送参数为同一个发送参数。该重复因子为关闭时，表示N个第一资源的发送参数不为同一个发送参数。例如，如图8所示，重复因子为repetition，该重复因子为关闭。“Repetition：ON”表示重复因子为开启。“Repetition：OFF”表示重复因子为关闭。
702、网络设备在N个第一资源分别发送第一参考信号。
703、网络设备在第二资源发送第二参考信号。
本申请实施例中，网络设备向终端设备发送配置信息之后，网络设备可在N个第一资源分别发送第一参考信号以及在第二资源发送第二参考信号。
704、终端设备测量N个第一资源上的信号强度，得到N个第一信号强度。
705、终端设备对第二资源上的信号强度进行N次测量，得到N个第二信号强度。
本申请实施例中，终端设备接收网络设备发送的配置信息之后，可测量N个第一资源上的信号强度，得到N个第一信号强度，以及对第二资源上的信号强度进行N次测量，得到N个第二信号强度。
在一种可能的实现中，终端设备测量N个第一资源上的信号强度的具体实施方式为：通过N个第一资源的接收参数测量N个第一资源上的信号强度；终端设备对第二资源上的信号强度进行N次测量的具体实施方式为：通过N个第一资源的接收参数对第二资源上的信号强度进行N次测量。
或者，可以表达为：N个第二资源中的各个第二资源与其关联的第一资源的接收参数是QCL的。或者，可以表达为：N个第二资源中的各个第二资源与其关联的第一资源的接收参数相同。
在一种可能的实现中，第二资源的周期为第一资源的周期的1/N倍。在该可能的实现方式中，网络设备在一个第一资源的周期内在第二资源发送N次参考信号。通过设置第二资源的周期为第一资源的周期的1/N倍，有利于降低测量结果上报周期的时长，有利于提升波束训练的速度。
举例来说，以终端设备在一个测量结果上报周期内进行的测量为例进行说明。如图9 所示，CSI-RS resource#1和CSI-RS resource#2的发送参数不相同，且接收参数也不相同。CSI-RS resource#1和CSI-RS resource#2的周期为10ms(毫秒)。一个测量结果上报周期为10ms。CSI-RS resource#11的周期为5ms。终端设备在CSI-RS resource#1对应的资源测量一次信号强度，在CSI-RS resource#2对应的资源测量一次信号强度。终端设备在一个测量结果上报周期内总共在CSI-RS resource#11对应的资源测量两次信号强度。
其中，CSI-RS resource#1的发送参数为波束a1，CSI-RS resource#2的发送参数为波束a2，CSI-RS resource#11的发送参数为波束a3。CSI-RS resource#1的接收参数为波束b1。终端设备通过波束b1在CSI-RS resource#1对应的资源测量CSI-RS1的信号强度，得到第一信号强度P1。终端设备通过波束b2在CSI-RS resource#2对应的资源测量CSI-RS2的信号强度，得到第一信号强度P2。网络设备在10ms内通过波束a3在CSI-RS resource#11发送两次CSI-RS11。终端设备通过波束b1测量第一次发送的CSI-RS11的信号强度，得到第二信号强度P11。终端设备通过波束b2测量第二次发送的CSI-RS11的信号强度，得到第二信号强度P12。可见，如果第二资源的周期与第一资源的周期相同，那么测量两次CSI-RS11的信号强度需要20ms。一次测量结果上报周期将变为20ms。因此，通过将第二资源的周期设置为第一资源的周期的1/N倍，有利于降低测量结果上报周期的时长，有利于提升波束训练的速度。
在一种可能的实现中，第二资源的周期与所述第一资源的周期相同，测量N个第二信号强度的时域范围小于或等于一个时间单元的时间长度，即测量N个第二信号强度的总时长小于或等于一个时间单元的时间长度。可选的，一个时间单元为一个正交频分复用(Orthogonal frequency divided multiplexing，OFDM)符号。或者，一个时间单元也可以为两个OFDM符号、三个OFDM符号或四个OFDM符号等。或者，时间单元也可以为一个时隙，一个子帧，一毫秒等。或者，时间单元也可以为两个时隙，两个子帧，两毫秒等。通过实施该可能的实现方式，有利于降低测量结果上报周期的时长，有利于提升波束训练的速度。
例如，在图9中，CSI-RS resource#1和CSI-RS resource#2的周期为10ms(毫秒)。一个测量结果上报周期为10ms。CSI-RS resource#11的周期为10ms。终端设备通过波束b1在CSI-RS resource#1对应的资源测量CSI-RS1的信号强度，得到第一信号强度P1。终端设备通过波束b2在CSI-RS resource#2对应的资源测量CSI-RS2的信号强度，得到第一信号强度P2。网络设备在10ms内通过波束a3在CSI-RS resource#11对应的资源发送1次CSI-RS11。网络设备发送1次CSI-RS11的持续时间等于一个OFDM符号。在一个OFDM符号内，终端设备对CSI-RS11的信号强度总共进行两次测量。第一次测量时，终端设备通过波束b1对CSI-RS11的信号强度进行测量，得到第二信号强度P11。第二次测量时，终端设备切换至波束b2对CSI-RS11的信号强度进行测量，得到第二信号强度P12。
在一种可能的实现中，每次测量第二信号强度的时域范围小于或等于N IFFT/N-N CP/N，所述N CP为循环前缀的时间长度，该N IFFT为一个时间单元的时间长度。
在一种可能的实现中，测量N个第二信号强度在循环前缀之后执行。
706、终端设备向网络设备上报一个或多个第一SINR。
本申请实施例中，该第一SINR为基于N个第一信号强度和N个第二信号强度得到的N个SINR中的SINR。
例如，终端设备测量得到上述第一信号强度P1、第一信号强度P2、第二信号强度P11 和第二信号强度P12。终端设备可以确定2个SINR。SINR1＝P1/(P11+N1)。SINR2＝P2/(P12+N2)。其中，N1和N2为噪声功率。N1和N2可以相同或不同。终端设备可以向网络设备上报SINR1和SINR2。或者，终端设备可以向网络设备上报SINR1和SINR2中的最大值或最小值。
在一种可能的实现中，终端设备向网络设备上报一个第一SINR，该第一SINR为基于N个第一信号强度之和，以及N个第二信号强度之和得到的。例如，第一SINR＝(P1+P2)/(P11+P12+N1)。通过可能的实现，可以实现干扰累加的功能。在终端设备经历的干扰环境较为复杂时，可以使干扰测量更加准确。
在一种可能的实现中，如果终端设备测量在一个时间单元的时间长度内测量了1次第一信号强度，且在一个时间单元的时间长度内测量了N次第二信号强度，在计算SINR时，需要考虑对测得的信号强度进行缩放(scaling)。也就是说，终端设备基于第一信号强度和第二信号强度以及缩放因子来确定SINR。该缩放因子与N相关。例如，该缩放因子等于N或为N的整数倍。例如，终端设备测量得到第一信号强度P1、第一信号强度P2、第二信号强度P11和第二信号强度P12。SINR1＝P1/(2*P11+N1)，SINR2＝P2/(2*P12+N2)。或者，SINR1＝0.5*P1/(P11+N1)，SINR2＝0.5*P2/(P12+N2)。
可选的，假设终端设备在一个时间单元的时间长度测量1次第一信号强度所需要占用的CSI计算单元(CSI processing unit，CPU)为1。如果终端设备需要在测量在一个时间单元的时间长度测量N次第二信号强度，那么终端设备处理第二资源所需要占用的CSI计算单元(CSI processing unit，CPU)为W，W为一个大于1小于等于N的数。
在一种可能的实现中，N个第一资源的接收参数相同时，也可以对第二资源上的信号强度进行一次测量，得到一个第二信号强度。向网络设备上报的第一SINR为基于N个第一信号强度和一个第二信号强度得到的N个SINR中的SINR。
例如，图8中的CSI-RS resource#1和CSI-RS resource#2的接收参数相同，均为波束b1。终端设备通过波束b1在CSI-RS resource#1对应的资源测量CSI-RS1的信号强度，得到第一信号强度P1。终端设备通过波束b1在CSI-RS resource#2对应的资源测量CSI-RS2的信号强度，得到第一信号强度P2。终端设备通过波束b1在CSI-RS resource#11对应的资源测量CSI-RS11的信号强度，得到第二信号强度P11。终端设备可以得到SINR1＝P1/(P11+N1)，SINR2＝P2/(P11+N2)。终端设备向网络设备上报SINR1和SINR2中的一个或多个。
在一种可能的实现中，终端设备对第二资源上的信号强度进行Z次测量，得到Z个第二信号强度。其中Z是第一资源集合中不同的接收参数的数目。
在一种可能的实现中，第二资源的周期为第一资源的周期的1/Z倍。其中Z是第一资源集合中不同的接收参数的数目。
在一种可能的实现中，终端设备可以上报能力信息，该能力信息指示终端设备是否支持图7所对应的实施例所描述的方法。
在一种可能的实现中，协议预定义或者网络设备可指示终端设备执行图7所对应的实施例所描述的方法。
在图7所描述的方法中，网络设备在第一资源集合配置N个第一资源的标识，在第二资源集合配置N个相同的第一资源的标识，该N个第一资源的标识与该N个第二资源的标识一一对应。因此，通过实施图7所描述的方法，有利于节省资源的开销。
下面结合图10对如何节省CMR资源的开销的另一种方法进行介绍：
请参见图10，图10是本申请实施例提供的一种信息上报方法的流程示意图。如图10所示，该信息上报方法包括如下步骤1001～步骤1004。图10所示的方法执行主语可以为网络设备和终端设备，或主语可以为网络设备中的芯片和终端设备中的芯片。图10以网络设备和终端设备为方法的执行主体为例进行说明。本申请实施例的其他附图所示的信息上报方法的执行主语同理，后文不再赘述。其中：
1001、网络设备向终端设备发送配置信息。
其中，该配置信息用于配置第一资源集合，该第一资源集合中的资源标识对应的资源用于信道测量，该第一资源集合中包括N个第一资源的标识，该N个第一资源的标识相同，该N为大于1的整数。由于该第一资源集合中包括N个第一资源的标识，且N个第一资源的标识相同。因此，可以理解为该第一资源集合包括N个相同的第一资源，或可以理解为第一资源集合包括一个第一资源。
举例来说，如图11所示，第一资源集合为资源集合#1(resourceset#1)对应的资源集合。其中，第一资源集合包括两个相同的第一资源的标识，第一资源的标识为CSI-RS resource#1。
可选的，配置信息中还包括重复因子，该重复因子为开启时，表示N个第一资源的发送参数为同一个发送参数。该重复因子为关闭时，表示N个第一资源的发送参数不为同一个发送参数。例如，如图11所示，重复因子为repetition。“Repetition：ON”表示重复因子为开启。“Repetition：OFF”表示重复因子为关闭。图11以重复因子为开启为例。
1002、网络设备在第一资源发送参考信号。
本申请实施例中，网络设备向终端设备发送配置信息之后，网络设备在第一资源发送参考信号。
1003、终端设备对第一资源上的信号强度进行N次测量，得到N个信号强度。
本申请实施例中，终端设备接收配置信息之后，对第一资源上的信号强度进行N次测量，得到N个信号强度。
其中，终端设备对第一资源上的信号强度进行N次测量的具体实现方式包括以下两种方式：
方式一：网络设备采用一个发送参数在第一资源上发送一次或N次参考信号，则终端设备使用N个不同的接收参数对第一资源上的信号强度进行N次测量。
例如，如图11和图12所示，配置信息中的重复因子为开启。两个CSI-RS resource#1的发送参数均为发送波束a1。网络设备通过波束a1在一个测量结果上报周期内发送1次或2次CSI-RS1。排列第一位的CSI-RS resource#1对应接收波束b1，排列第二位的CSI-RS resource#1对应接收波束b2。终端设备通过接收波束b1对CSI-RS resource#1对应的资源上的CSI-RS1进行第一次测量，得到信号强度P1。终端设备通过接收波束b2对CSI-RS resource#1对应的资源上的CSI-RS1进行第二次测量，得到信号强度P2。
在一种可能的实现中，终端设备进行N次测量的时域范围小于或等于一个时间单元的时间长度，即终端设备进行N次测量的总时长小于或等于一个时间单元的时间长度。可选的，一个时间单元为一个OFDM符号。或者，一个时间单元也可以为两个OFDM符号、三个OFDM符号或四个OFDM符号等。或者，时间单元也可以为一个时隙，一个子帧， 一毫秒等。或者，时间单元也可以为两个时隙，两个子帧，两毫秒等。通过实施该可能的实现方式，有利于降低测量结果上报周期的时长，有利于提升波束训练的速度。
例如，如图12所示，网络设备可以在一个测量结果上报周期内发送一次CSI-RS1。网络设备发送1次CSI-RS1的持续时间等于一个OFDM。在一个OFDM内，终端设备对CSI-RS1的信号强度总共进行两次测量。第一次测量时，终端设备通过波束b1对CSI-RS1的信号强度进行测量，得到信号强度P1。第二次测量时，终端设备切换至波束b2对CSI-RS1的信号强度进行测量，得到信号强度P2。
在一种可能的实现中，N次测量中的每次测量的时域测量范围小于或等于N IFFT/N，N IFFT为一个时间单元的时间长度。
在一种可能的实现中，N次测量中的每次测量的时域测量范围小于或等于N IFFT/N-N CP/N，N CP为循环前缀的时间长度，N IFFT为一个时间单元的时间长度。循环前缀为保护间隔，不能用于发送参考信号，因此，应保证N次测量中的每次测量的时域测量范围小于或等于N IFFT/N-N CP/N。
在一种可能的实现中，N次测量在循环前缀之后执行。例如，如图13所示，一个时间单元内可以有一个循环前缀，N次测量均在该循环前缀之后执行。再如，如图14所示，一个时间单元内可以有多个循环前缀，N次测量中的每次测量均在一个循环前缀之后执行。
方式二：网络设备采用N个不同的发送参数在第一资源上发送N次参考信号。终端设备可以使用相同的接收参数对第一资源上的信号强度进行N次测量。
例如，假设配置信息中的重复因子为关闭。如图15所示，排列第一位的CSI-RS resource#1对应发送波束a1，排列第二位的CSI-RS resource#1对应发送波束a2。两个CSI-RS resource#1的接收参数均为接收波束b1。终端设备通过接收波束b1对波束a1发送的CSI-RS1进行第一次测量，得到信号强度P1。终端设备通过接收波束b1对波束a2发送的CSI-RS1进行第二次测量，得到信号强度P2。
在一种可能的实现中，网络设备通过N个发送参数发送N次参考信号的时域范围小于或等于一个时间单元的时间长度，即网络设备通过N个发送参数发送N次参考信号的总时长小于或等于一个时间单元的时间长度。相应地，终端设备进行N次测量的时域范围小于或等于一个时间单元的时间长度，即终端设备进行N次测量的总时长小于或等于一个时间单元的时间长度。可选的，一个时间单元为一个OFDM符号。或者，一个时间单元也可以为两个OFDM符号、三个OFDM符号或四个OFDM符号等。通过实施该可能的实现方式，有利于降低测量结果上报周期的时长，有利于提升波束训练的速度。
再如，如图15所示，在一个OFDM内，网络设备对CSI-RS1总共进行两次发送。第一次发送时，网络设备通过波束a1对CSI-RS1进行发送。第二次发送时，网络设备切换至波束a2对CSI-RS1进行发送。在一个OFDM内，终端设备对CSI-RS1的信号强度总共进行两次测量。第一次测量时，终端设备通过波束b1对波束a1发送的CSI-RS1的信号强度进行测量，得到信号强度P1。第二次测量时，终端设备通过波束b2对CSI-RS1的信号强度进行测量，得到信号强度P2。
在一种可能的实现中，网络设备通过N个发送参数每次发送参考信号的时域范围小于或等于N IFFT/N，该N IFFT为一个时间单元的时间长度。相应地，终端设备的N次测量中，每次测量的时域测量范围小于或等于N IFFT/N。
在一种可能的实现中，网络设备通过N个发送参数每次发送参考信号的时域范围小于 或等于N IFFT/N-N CP/N，该N CP为循环前缀的时间长度，该N IFFT为一个时间单元的时间长度。相应地，终端设备的N次测量中，每次测量的时域测量范围小于或等于N IFFT/N-N CP/N。
在一种可能的实现中，网络设备通过N个发送参数发送N次参考信号在循环前缀之后执行。相应地，终端设备的N次测量在循环前缀之后执行。
在一种可能的实现中，协议预定义或者网络设备还可以指示终端设备在小于或等于一个时间单元的时间长度内进行N次测量的方法，该方法包括以下方法中的任意一种：基于交织频分多址复用(Interleaved Frequency Division MultipleAccess，IFDMA)的信号发送和/或接收方法、扩大子载波间隔(larger subcarrier spacing)的信号发送和/或接收方法、基于离散傅里叶变换(Discrete Fourier Transform,DFT)的信号发送和/或接收方法。
1004、终端设备向网络设备上报N个信号强度中的第一信号强度。
本申请实施例中，终端设备测量得到N个信号强度之后，向网络设备上报N个信号强度中的第一信号强度。该第一信号强度可以是最小值或最大值。
在一种可能的实现中，配置信息中的重复因子为关闭时，终端设备还向网络设备上报第一信号强度对应的第一资源的标识在第一资源集合中的位置。这样有利于网络设备确定出测量第一信号强度采用的发送参数。
在一种可能的实现中，终端设备可以上报能力信息，该能力信息指示终端设备是否支持图10所对应的实施例所描述的方法。
在一种可能的实现中，协议预定义或者网络设备可指示终端设备执行图10所对应的实施例所描述的方法。
在现有的波束训练中，采用不同的CMR资源进行训练。通过实施图10所描述的方法，采用相同的CMR资源就能进行波束训练，有利于节省CMR资源开销。
在一种可能的实现中，本申请提供一种上行波束训练的方法，该方法包括：网络设备发送，该配置信息用于配置第一资源集合，该第一资源集合中的资源标识对应的资源用于上行探测，第一资源集合中包括N个第一资源的标识，该N个第一资源的标识相同，N为大于1的整数。终端设备接收该配置信息之后，在第一资源发送参考信号。网络设备发送配置信息之后，在第一资源测量参考信号。

请参见图16，图16示出了本申请实施例的一种通信装置的结构示意图。图16所示的通信装置可以用于执行上述图4所描述的方法实施例中终端设备的部分或全部功能。该装置可以是终端设备，也可以是终端设备中的装置，或者是能够和终端设备匹配使用的装置。其中，该通信装置还可以为芯片***。图16所示的通信装置可以包括接收单元1601和发 送单元1602。可选的，接收单元1601和发送单元1602也可集成于一个单元中，该单元可以称为收发单元，下文同理，下文不再赘述。可选的，通信装置还可包括处理单元，用于进行数据处理，图16以通信装置包括接收单元1601和发送单元1602为例进行说明，下文同理，下文不再赘述。其中：
接收单元1601，用于接收网络设备发送的配置信息，配置信息用于配置第一资源集合和第二资源集合，第一资源集合中的资源标识对应的资源用于信道测量，第二资源集合中的资源标识对应的资源用于干扰测量，第一资源集合中包括N个第一资源的标识，N个第一资源的标识相同，第二资源集合中包括N个第二资源的标识，N个第一资源的标识与N个第二资源的标识一一对应，N为大于1的整数；接收单元1601，还用于测量第一资源上的信号强度，得到第一信号强度；接收单元1601，还用于测量N个第二资源上的信号强度，得到N个第二信号强度；发送单元1602，用于基于第一信号强度和N个第二信号强度向网络设备上报第一信干噪比SINR。
