下面，对本申请的应用场景进行说明：
图1示出了本申请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：终端10和网络设备20。
终端10的数量通常为多个，每一个网络设备20所管理的小区内可以分布一个或多个终端10。终端10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它处理设备，以及各种形式的用户设备(User Equipment，UE)、移动台(Mobile Station，MS)等等。为方便描述，本申请实施例中，上面提到的设备统称为终端。
网络设备20是一种部署在接入网中用以为终端10提供无线通信功能的装置。为方便描述，本申请实施例中，上述为终端10提供无线通信功能的装置统称为网络设备。网络设备20与终端10之间可以通过空口建立连接，从而通过 该连接进行通信，包括信令和数据的交互。网络设备20的数量可以有多个，两个邻近的网络设备20之间也可以通过有线或者无线的方式进行通信。终端10可以在不同的网络设备20之间进行切换，也即与不同的网络设备20建立连接。
该网络设备20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，具备网络设备功能的设备的名称可能会有所不同，例如在5G NR系统中，称为gNodeB或者gNB。随着通信技术的演进，“网络设备”这一名称可能会变化。
图2示出了本申请一个示例性实施例提供的一种信息上报方法的流程图，示例性的可以应用于如图1所示的终端和网络设备中，该方法包括以下内容中的至少部分内容：
步骤201：终端向网络设备发送信道状态信息，信道状态信息包括至少两个CSI-RS的测量结果，至少两个CSI-RS对应的时域资源不同。
在本申请实施例中，终端和网络设备之间会进行交互，终端会基于网络设备发送的至少两个CSI-RS(Channel State Information-Reference Signal，信道状态信息参考信号)以得到信道状态信息，并且信道状态信息中包括CSI-RS的测量结果。
其中，至少两个CSI-RS对应的时域资源不同，也就是终端向网络设备发送的信道状态信息中包括的是不同时域资源的至少两个CSI-RS对应的测量结果。
步骤202：网络设备接收终端发送的信道状态信息。
在本申请实施例中，网络设备接收信道状态信息，进而确定不同时域资源的至少两个CSI-RS对应的测量结果。
在一些实施例中，至少两个CSI-RS的时域资源不同，也就是至少两个CSI-RS满足以下至少一项：
(1)至少两个CSI-RS对应的CSI-RS资源集不同。
(2)至少两个CSI-RS对应的CSI-RS资源索引不同。
(3)至少两个CSI-RS对应同一CSI-RS索引的不同发送时间标识。
在一个实施例中，至少两个CSI-RS对应的CSI-RS资源集不同。比如包含两个CSI-RS资源集，每个资源集里面包含的CSI-RS索引相同，而两个CSI-RS资源集中对应相同CSI-RS索引的两个CSI-RS对应不同的时域资源，即在不同时间发送。
在另一个实施例中，至少两个CSI-RS对应同一CSI-RS索引的不同发送时间标识。比如对一个CSI-RS索引，其在一段时间内会在不同时间重复发送N次，则发送时间标识分别对应第i次发送，i的取值为1～N。
本申请实施例中通过CSI-RS资源集、CSI-RS资源索引或发送时间标识来指示至少两个CSI-RS的时域资源不同，扩展了CSI-RS的指示方式，并且无需再单独上报每个CSI-RS的测量结果，也即是缩短了反馈时长，减少了反馈时延，并且节省了信令开销。
在一些实施例中，信道状态信息参考信号的发送方式可以包括多种情况，例如，该发送方式包含以下任意一项：
(1)周期性发送。
(2)在一个周期内发送N次，其中，N为大于0的整数。
(3)非周期性发送。
(4)半持续性发送。
在一些实施例中，该信道状态信息承载在PUCCH(Physical Uplink Control Channel，物理上行控制信道)，和/或PUSCH(Physical Uplink Shared Channel，物理上行共享信道)中。
需要说明的是，本申请实施例中的终端执行的步骤可以单独实现以形成一个新的实施例，网络设备执行的步骤可以单独实现以形成一个新的实施例。
本申请实施例提供的信息上报方法中，终端通过上报包括至少两个时域资源不同的CSI-RS对应的测量结果的信道状态信息，无需再单独上报每个CSI-RS的测量结果，也即是缩短了反馈时长，减少了反馈时延，并且节省了信令开销。
在图2所示的实施例的基础上，该信道状态信息中还包括至少两个CSI-RS中各个CSI-RS对应的时域资源对应的频域基向量。
在本申请实施例中，终端不仅上报对CSI-RS的测量结果，还需要上报各个CSI-RS对应的时域资源对应的频域基向量，由于各个CSI-RS对应的时域资源不同，也就是各个CSI-RS的发送时间点不同，终端可以通过信道状态信息上报各个时域资源对应的频域基向量。频域基向量也称为vector。
其中，该频域基向量为与CQI(Channel Quality Indicator，信道质量指示)对应的subband(子带)和/或PMI(Precoding Matrix Indicator，预编码矩阵指示)对应的subband相关的参数值。例如，频域基向量与CQI对应的subband相同， 或为CQI对应的subband的一半或1/R,R为大于1的整数。
可选地，对于至少两个CSI-RS中的各个CSI-RS，终端上报相同的频域基向量，也就是各个CSI-RS对应的时域资源对应的频域基向量相同。
可选地，对于至少两个CSI-RS中的各个CSI-RS，终端分别上报各个CSI-RS对应的时域资源对应的频域基向量，也就是不同的CSI-RS对应的时域资源对应的频域基向量可能相同，也可能不同。
本申请实施例提供的方案中，终端通过上报各个CSI-RS对应的时域资源对应的频域基向量，以便于网络设备获知各个CSI-RS对应的时域资源对应的频域基向量，保证终端上报的信道状态信息的全面性，提高传输性能。
在图2所示的实施例的基础上，至少两个CSI-RS的数量为M个，信道状态信息指示从N个CSI-RS中选取M个CSI-RS对应的组合标识，N为大于2的整数，M为大于1的整数，且M小于N。
在本申请实施例中，网络设备向终端发送N个CSI-RS，终端可以对这N个CSI-RS进行测量，而终端上报信道状态信息时，可以从N个CSI-RS中选取M个CSI-RS，上报选取的M个CSI-RS对应的组合标识。
在一些实施例中，N个CSI-RS中包含至少M个CSI-RS对应的时域资源不同，也就是N个CSI-RS对应M个时域资源，终端从N个时域资源中选取了M个时域资源。
在一些实施例中，信道状态信息通过包括的组合标识指示N个CSI-RS中的至少两个CSI-RS。
例如，N＝3即包含三个CSI-RS，分别为CSI-RS#1，CSI-RS#2，CSI-RS#3，且这三个CSI-RS对应的时域资源各不相同。M＝2，即从3个CSI-RS选择2个CSI-RS。那么包含如下三个组合：
组合1：CSI-RS#1，CSI-RS#2；
组合2：CSI-RS#1，CSI-RS#3；
组合3：CSI-RS#2，CSI-RS#3。
那么需要2bit来指示组合对应的组合标识，比如00指示组合1，01指示组合2，10指示组合3。
即按照组合数对2取对数，再向上取整以确定该组合标识需要的bit数，进而通过该bit对应的bit值指示组合标识，再确定组合标识对应了N个CSI-RS 中哪M个CSI-RS。
可选地，N和M中的至少一个的值由网络设备配置。
本申请实施例提供的方案中，终端通过信道状态信息上报从N个CSI-RS中选取的至少两个CSI-RS，以便于网络设备获知至少两个CSI-RS的选取情况，，保证终端上报的信道状态信息的全面性，提高传输性能。
在图2所示的实施例的基础上，信道状态信息还指示至少两个CSI-RS中各个CSI-RS对应的时域资源对应的波束。
在本申请实施例中，至少两个CSI-RS对应不同的时域资源，不同的时域资源可能对应相同的波束，也可能对应不同的波束，终端在上报信道状态信息时，也同步上报至少两个CSI-RS中各个CSI-RS对应的时域资源对应的波束。
其中，该至少两个CSI-RS中各个CSI-RS对应的时域资源对应的波束采用与天线端口数和/或过采样数相关的参数指示。
该天线端口数表示为N 1*N 2，其中N 1为第一维度的天线端口数，N 2为第二维度的天线端口数。过采样数表示为O1*O2，其中O1为第一维度的过采样数，O2为第二维度的过采样数。
例如，对应的波束采用与天线端口数和/或过采样数相关的参数来指示，其参数的取值范围为0～N 1*O 1-1，或0～N 2*O 2-1，或0～O 1*O 2-1，或0～O 1-1，或0～O 2-1，或0～N 1-1，或0～N 2-1，或0～N 1*O 1/2-1，或0～N 2*O 2/2-1或0～(从N 1*N 2中选出L的组合数)-1，其中L为大于1的整数。
可选地，对于至少两个CSI-RS中的各个CSI-RS，终端上报相同的波束，也就是各个CSI-RS对应的时域资源对应的波束相同。
可选地，对于至少两个CSI-RS中的各个CSI-RS，终端分别上报各个CSI-RS对应的时域资源对应的波束，也就是不同的CSI-RS对应的时域资源对应的波束可能相同也可能不同。
本申请实施例提供的方案中，终端通过上报各个CSI-RS对应的时域资源对应的波束，以便于网络设备获知各个CSI-RS对应的时域资源对应的波束，保证终端上报的信道状态信息的全面性，提高传输性能。
在图2所示的实施例的基础上，信道状态信息不仅指示至少两个CSI-RS对应的时域资源的波束，而且还包括至少两个CSI-RS对应的波束的第一幅度系数 和/或第一相位系数。
在本申请实施例中，对于各个CSI-RS来说，CSI-RS均对应一个时域资源，并且该时域资源对应的波束对应有第一幅度系数和/或第一相位系数，下面对如何确定第一幅度系数和第一相位系数进行说明。
一、确定第一幅度系数的方法：
在一些实施例中，CSI-RS对应的波束的第一幅度系数包含至少一个第二幅度系数。
在本申请实施例中，第一幅度系数指示CSI-RS对应的波束的幅度，并且该第一幅度系数中包含至少一个第二幅度系数，由至少一个第二幅度系数指示该第一幅度系数。
可选地，第一幅度系数为至少一个第二幅度系数的乘积。
在本申请实施例中，第一幅度系数中包含至少一个第二幅度系数，将至少一个第二幅度系数的乘积确定为第一幅度系数。
可选地，至少一个第二幅度系数包含宽带幅度系数和/或窄带幅度系数。
在本申请实施例中，对于至少一个第二幅度系数来说，至少一个第二幅度系数可以为宽带幅度系数，或者为窄带幅度系数，或者不仅包含宽带幅度系数，还包含窄带幅度系数。
其中，宽带是指整个带宽，或小区对应的整个带宽，或终端可用的整个带宽，或终端使用的整个带宽，或终端被配置的整个带宽。如激活BWP(Band WidthPart，部分带宽)对应的带宽。
窄带是指把整个带宽分成多个子带。如带宽为24–72物理资源块(Physical Resource Block，PRB)时，子带大小为4或8个PRB；带宽为73–144PRB时，子带大小为8或16个PRB；带宽为145–275PRB时，子带大小为16或32个PRB。进一步还可以把子带分成多个频域单元或频域基向量。或者，窄带为频域单元或频域基向量。
可选地，至少一个第二幅度系数包含以下至少一项：时间点参考幅度，极化参考幅度和频域基向量幅度。
在本申请实施例中，对于各个CSI-RS对应的时域资源来说，该时域资源包含多个极化方向，该时间点参考幅度对于多个极化方向中的每个极化方向是相同的。极化参考幅度对于一个极化方向中的所有频域基向量是相同的。而频域基向量幅度对于该时域资源对应的多个频域基向量是独立的。
需要说明的是，本申请实施例中的信道状态信息包括至少两个CSI-RS对应的信息，而每个CSI-RS对应时域资源，先指示至少两个CSI-RS中时间点参考幅度中对应最大幅度值的CSI-RS，其幅度值量化为1，对于其他CSI-RS的时间点参考幅度来说，均为相对于最大幅度值的差分值。
其中，信道状态信息中还包括最大时间点参考幅度对应的时域资源的位置，以便于指示哪个时域资源对应的时间点参考幅度最大。
可选地，最大的时间点参考幅度为1，相对于该最大的时间点参考幅度的其它时间点参考幅度均小于1。
例如，信道状态信息包括3个CSI-RS对应的信息，这三个CSI-RS分别为第一CSI-RS、第二CSI-RS和第三CSI-RS，并且第二CSI-RS对应的时间点参考幅度最大，则第一CSI-RS对应的时间点参考幅度为第二CSI-RS对应的时间点参考幅度与第一CSI-RS的差分值的和或乘积。第三CSI-RS对应的时间点参考幅度为第二CSI-RS对应的时间点参考幅度与第三CSI-RS的差分值的和或乘积。
在另一些实施例中，对于至少两个CSI-RS对应的时域资源来说，存在一个时域资源对应的时间点参考幅度为最大时间点参考幅度，该时域资源对应多个极化方向，对于其中一个极化方向来说，该极化方向对应的极化参考幅度即为1，该极化方向对应的频域基向量幅度均采用相对于该极化参考幅度的差分值表示。而对于其他极化方向来说，其他极化方向分别分配一个极化参考幅度，其他极化方向对应的频域基向量幅度均采用相对于该极化参考幅度的差分值表示。
也就是说，在一个极化方向上，对于各个频域基向量幅度来说，该频域基向量幅度均为极化参考幅度与该频域基向量幅度对应的差分值的和或乘积。
另外，对于其他时间点参考幅度不是最大时间点参考幅度的时域资源来说，该时域资源也对应多个极化方向，分别为每个极化方向分配一个极化参考幅度，每个极化方向对应的频域基向量幅度均采用相对于该极化方向对应的极化参考幅度的差分值表示。
二、确定第一相位系数的方法：
在一些实施例中，CSI-RS对应的波束的第一相位系数包含至少一个第二相位系数。
在本申请实施例中，第一相位系数指示CSI-RS对应的波束的相位，并且该第一相位系数中包含至少一个第二相位系数，由至少一个第二相位系数指示该 第一相位系数。
可选地，第一相位系数为至少一个第二相位系数的乘积。
在本申请实施例中，第一相位系数中包含至少一个第二相位系数，将至少一个第二相位系数的乘积确定为第一相位系数。
可选地，至少一个第二相位系数包含宽带相位系数和/或窄带相位系数。
在本申请实施例中，对于至少一个第二相位系数来说，至少一个第二相位系数可以为宽带相位系数，或者为窄带相位系数，或者不仅包含宽带相位系数，还包含窄带相位系数。
其中，宽带是指整个带宽，或小区对应的整个带宽，或终端可用的整个带宽，或终端使用的整个带宽，或终端被配置的整个带宽。如激活BWP对应的带宽。
窄带是指把整个带宽分成多个子带。如带宽为24–72物理资源块PRB时，子带大小为4或8个PRB；带宽为73–144PRB时，子带大小为8或16个PRB；带宽为145–275PRB时，子带大小为16或32个PRB。进一步还可以把子带分成多个频域单元或频域基向量。或者，窄带为频域单元或频域基向量。
可选地，至少一个第二相位系数包含以下至少一项：时间点参考相位，极化参考相位和频域基向量相位。
在本申请实施例中，对于各个CSI-RS对应的时域资源来说，该时域资源包含多个极化方向，该时间点参考相位对于多个极化方向中的每个极化方向是相同的。极化参考相位对于一个极化方向中的所有频域基向量是相同的。而频域基向量相位对于该时域资源对应的多个频域基向量是独立的。
需要说明的是，本申请实施例中的信道状态信息包括至少两个CSI-RS对应的信息，而每个CSI-RS对应时域资源，先指示至少两个CSI-RS中时间点参考相位中对应最大相位值的CSI-RS，其相位值量化为0，对于其他CSI-RS的时间点参考相位来说，均为相对于最大相位值的差分值。
其中，信道状态信息中还包括最大时间点参考相位对应的时域资源的位置，以便于指示哪个时域资源对应的时间点参考相位最大。
可选地，最大的时间点参考相位为0。
例如，信道状态信息包括3个CSI-RS对应的信息，这三个CSI-RS分别为第一CSI-RS、第二CSI-RS和第三CSI-RS，并且第二CSI-RS对应的时间点参考相位最大，则第一CSI-RS对应的时间点参考相位为第二CSI-RS对应的时间 点参考相位与第一CSI-RS的差分值的和或乘积。第三CSI-RS对应的时间点参考相位为第二CSI-RS对应的时间点参考相位与第三CSI-RS的差分值的和或乘积。
在另一些实施例中，对于至少两个CSI-RS对应的时域资源来说，存在一个时域资源对应的时间点参考相位为最大时间点参考相位，该时域资源对应多个极化方向，对于其中一个极化方向来说，该极化方向对应的极化参考相位即为0，该极化方向对应的频域基向量相位均采用相对于该极化参考相位的差分值表示。而对于其他极化方向来说，其他极化方向分别分配一个极化参考相位，其他极化方向对应的频域基向量相位均采用相对于该极化参考相位的差分值表示。
也就是说，在一个极化方向上，对于各个频域基向量相位来说，该频域基向量相位均为极化参考相位与该频域基向量相位对应的差分值的和或乘积。
另外，对于其他时间点参考相位不是最大时间点参考相位的时域资源来说，该时域资源也对应多个极化方向，分别为每个极化方向分配一个极化参考相位，每个极化方向对应的频域基向量相位均采用相对于该极化方向对应的极化参考相位的差分值表示。
本申请实施例提供的方案中，通过信道状态信息即可指示波束的幅度和/或相位，以便于网络设备获知各个CSI-RS对应的时域资源对应的波束的幅度和/或相位，保证终端上报的信道状态信息的全面性，提高传输性能。
需要说明的是，上述实施例可以拆分为新实施例，或与其他实施例互相组合为新实施例，本申请对实施例之间的组合不做限定。
