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信息上报方法的流程图，示例性的可以由如图1所示的终端和网络设备执行，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第一信道状态信息，第一信道状态信息包括相对于第二信道状态信息的差分信息，第二信道状态信息的发送时刻早于第一信道状态信息的发送时刻。
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CSI-RS(Channel State Information-Reference Signal，信道状态信息参考信号)和/或SSB(Synchronization Signal and PBCH Block,同步信号块)进行测量，以得到信道状态信息，并且终端向网络设备发送相对于第二信道状态信息的第一信道状态信息，以便于通过该第一信道状态信息中的差分信息来指示测量得到的信道状态信息。
其中，该第二信道状态信息的发送时刻早于第一信道状态信息，因此终端可以通过相对于第二信道状态信息的差分信息来指示第一信道状态信息，
步骤202：网络设备接收终端发送的第一信道状态信息。
在本申请实施例中，网络设备接收第一信道状态信息，则根据该第一信道状态信息包括的差分信息和第二信道状态信息，确定终端的信道状态信息。
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，终端通过上报的差分信息来指示信道状态信息，也就是通过差分信息和位于第一信道状态信息之前的第二信道状态信息来指示本次发送的信道状态信息，无需再发送完整的信道状态信息，节省信令开销。
在图2所示的实施例的基础上，该第一信道状态信息还需要指示第二信道状态信息的位置。
在一些实施例中，该第一信道状态信息还包括第一指示信息，第一指示信息指示第二信道状态信息为第一信道状态信息之前的第N个信息，N为大于0的正整数。
在本申请实施例中，第二信道状态信息的发送时刻早于第一信道状态信息的发送时刻，但是，在第二信道状态信息的发送时刻与第一信道状态信息的发送时刻之间的时间段内，还可能存在其他的信道状态信息，因此，为了指示差分信息是相对于哪个信道状态信息的信息，通过第一指示信息来指示该第二信道状态信息为第一信道状态信息之前的第N个信息，该N为大于0的正整数。
例如，该第二信道状态信息是位于第一信道状态信息之前的第1个信息，或者，该第二信道状态信息是位于第一信道状态信息之前的第2个信息，也就是该第二信道状态信息和第一信道状态信息之间还存在一个信道状态信息。
本申请实施例提供的方法中，通过第一指示信息即可指示第二信道状态信息与第一信道状态信息之间的位置关系，进而确定第二信道状态信息，以便于基于该第二信道状态信息确定本次发送的第一信道状态信息对应的完整的信道 状态信息，提高传输准确性。
在图2所示的实施例的基础上，终端还会上报第一信道状态信息和第二信道状态信息对应的波束是否相同。
在一些实施例中，第一信道状态信息还包括第二指示信息，第二指示信息指示第一信道状态信息对应的波束与第二信道状态信息对应的波束是否相同。
在本申请实施例中，终端需要上报第一信道状态信息对应的波束，而此时在第一信道状态信息中包括第二指示信息，通过该第二指示信息来指示第一信道状态信息对应的波束与第二信道状态信息对应的波束是否相同，在该第二指示信息指示第一信道状态信息对应的波束与第二信道状态信息对应的波束相同时，也即是该第一信道状态信息对应的波束就是第二信道状态信息对应的波束。
可选地，该第二指示信息指示第一信道状态信息对应的波束与第二信道状态信息对应的波束不同时，则终端还需要上报第一信道状态信息对应的波束，也即是在第一信道状态信息对应的波束与第二信道状态信息对应的波束不同的情况下，第一信道状态信息还包括第一信道状态信息对应的波束。
可选地，该第一信道状态信息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。
其中，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。
本申请实施例提供的方法中，终端通过上报第二指示信息来指示第一信道状态信息对应的波束是否与第二信道状态信息对应的波束相同，以便于终端决定是否重新上报第一信道状态信息对应的波束，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，终端还会上报第一信道状态信息和第二信道状态信息对应的频域基向量是否相同。
在一些实施例中，第一信道状态信息还包括第三指示信息，第三指示信息指示第一信道状态信息对应的频域基向量与第二信道状态信息对应的频域基向量是否相同。
在本申请实施例中，终端需要上报第一信道状态信息对应的频域基向量，而此时在第一信道状态信息中包括第三指示信息，通过该第三指示信息来指示第一信道状态信息对应的频域基向量与第二信道状态信息对应的频域基向量是否相同，在该第三指示信息指示第一信道状态信息对应的频域基向量与第二信道状态信息对应的频域基向量相同时，也即是该第一信道状态信息对应的频域基向量就是第二信道状态信息对应的频域基向量。
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，在第一信道状态信息对应的频域基向量与第二信道状态信息对应的频域基向量不同的情况下，第一信道状态信息还包括第一信道状态信息对应的频域基向量。
本申请实施例提供的方法中，终端通过上报第三指示信息来指示第一信道状态信息对应的频域基向量是否与第二信道状态信息对应的频域基向量相同，以便于终端决定是否重新上报第一信道状态信息对应的频域基向量，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，终端还会上报被选择的波束和/或频域基向量对应的第一幅度系数和/或第一相位系数。
在本申请实施例中，终端确定被选择的波束和/或频域基向量后，还会上报对应的第一幅度系数和/或第一相位系数。
一、确定第一幅度系数的方法：
在一些实施例中，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，第一幅度系数指示被选择的波束和/或频域基向量的幅度，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 Width Part，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，对于第一信道状态信息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，对于第一信道状态信息对应的时域资源来说，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最大时间点参考幅度，其最大时间点参考幅度量化为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。
在一些实施例中，在第一信道状态信息对应的最强幅度大于第二信道状态信息对应的最强幅度的情况下，确定时间点参考幅度。
在本申请实施例中，终端需要对比第一信道状态信息对应的最强幅度和第 二信道状态信息对应的最强幅度的大小关系，若第一信道状态信息对应的最强幅度大于第二信道状态信息对应的最强幅度，则需要重新确定一个时间点参考幅度，若第一信道状态信息对应的最强幅度不大于第二信道状态信息对应的最强幅度，则直接将第二信道状态信息对应的最强幅度确定为时间点参考幅度。
可选地，终端上报1比特指示第一信道状态信息对应的最强幅度和第二信道状态信息对应的最强幅度的大小关系。例如，若该比特为0，说明第一信道状态信息对应的最强幅度大于第二信道状态信息对应的最强幅度，若该比特为1，说明第一信道状态信息对应的最强幅度不大于第二信道状态信息对应的最强幅度。或者，若该比特为0，说明第一信道状态信息对应的最强幅度不大于第二信道状态信息对应的最强幅度，若该比特为1，说明第一信道状态信息对应的最强幅度大于第二信道状态信息对应的最强幅度。
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，第一相位系数指示被选择的波束和/或频域基向量对应的相位，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(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，对于第一信道状态信息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，对于第一信道状态信息对应的时域资源来说，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最大时间点参考相位，最大时间点参考相位为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。
可选地，在确定第一相位系数之前，先反馈第一信道状态信息的最强幅度对应的相位以及第二信道状态信息的最强幅度对应的相位。
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。
