在一些实施例中，本公开的技术方案可适用于Open RAN架构，此时，本公开实施例所涉及的接入网设备间或者接入网设备内的接口可变为Open RAN的内部接口，这些内部接口之间的流程和信息交互可以通过软件或者程序实现。
在一些实施例中，接入网设备可以由集中单元(central unit，CU)与分布式单元(distributed unit，DU)组成的，其中，CU也可以称为控制单元(control unit)，采用CU-DU的结构可以将接入网设备的协议层拆分开，部分协议层的功能放在CU集中控制，剩下部分或全部协议层的功能分布在DU中，由CU集中控制DU，但不限于此。
在一些实施例中，核心网设备可以是一个设备，包括一个或多个网元，也可以是多个设备或设备群，分别包括上述一个或多个网元中的全部或部分。网元可以是虚拟的，也可以是实体的。核心网例如包括演进分组核心(Evolved Packet Core，EPC)、5G核心网络(5G Core Network，5GCN)、下一代核心(Next Generation Core，NGC)中的至少一者。

下述本公开实施例可以应用于图1所示的通信系统100、或部分主体，但不限于此。图1所示的各主体是例示，通信系统可以包括图1中的全部或部分主体，也可以包括图1以外的其他主体，各主体数量和形态为任意，各主体可以是实体的也可以是虚拟的，各主体之间的连接关系是例示，各主体之间可以不连接也可以连接，其连接可以是任意方式，可以是直接连接也可以是间接连接，可以是有线连接也可以是无线连接。

在R18中，提出了在多传输接收节点(Transmission Reception Point，TRP)进行相干联合传输(coherent joint transmission，CJT)。其中，多TRP进行相干联合传输的情况下，多个TRP之间可以理想同步，并且多个TRP之间有理想回程链路，便可以保证多TRP发送的信息能同时到达终端。或者多TRP发送的信息到达时间差异在某一时间阈值内，例如循环前缀(cyclic prefix，CP)之内，能够保证终端能够同时接收不同TRP发送的数据。
可以理解的是，若多个TRP之间到达终端的时间差异较大(例如，不同时或者时间差异大于循环前缀长度)，则终端无法同时接收到不同TRP发送的信息。
基于此，本公开实施例提出了一种信道状态信息(Channel State Information，CSI)上报方法。
图2是本公开实施例示出的信道状态信息上报方法的交互示意图。如图2所示，本公开实施例涉及信道状态信息上报方法，上述方法包括：
步骤S2101，网络设备102向终端101发送第一参考信号资源的配置信息。
在一些实施例中，终端101获取第一参考信号资源。
在一些实施例中，终端101接收第一参考信号资源。
在一些实施例中，终端101接收来自网络设备102的第一参考信号资源。
在一些实施例中，第一参考信号资源的数目可以为一个或多个。
在一些实施例中，第一参考信号资源包括信道测量资源(Channel Measurement Resource，CMR)。
可选地，第一参考信号资源包括一个CMR。
在一些实施例中，一个CMR中包括多个参考信号资源。
示例性的，一个CMR中包括多个信道状态信息参考信号资源(Channel State Information Reference Signal resource，CSI-RS resource)。
总之，网络设备可以将一个参考信号资源的情况告知终端，例如网络设备可以向终端发送一个或多个参考信号资源(参考信号资源配置)，以便终端针对参考信号资源进行测量，从而获取时间差异信息。
在一些实施例中，“发送”、“发射”、“上报”、“下发”、“传输”、“双向传输”、“发送和/或接收”等术语可以相互替换。
在一些实施例中，“获取”、“获得”、“得到”、“接收”、“传输”、“双向传输”、“发送和/或接收”可以相互替换，其可以解释为从其他主体接收，从协议中获取，从高层获取，自身处理得到、自主实现等多种含义。
在一些实施例中，终端101获取网络设备102发送的第一参考信号资源配置信息，并基于第一参考信号资源配置信息进行第一参考信号资源配置，从而确定第一参考信号资源。
当然，应当理解，终端也可通过其他方式确定第一参考信号资源，并相应地进行测量以及上报。
在一些实施例中，信息等的名称不限定于实施例中所记载的名称，“信息(information)”、“消息(message)”、“信号(signal)”、“信令(signaling)”、“报告(report)”、“配置(configuration)”、“指示(indication)”、“指令(instruction)”、“命令(command)”、“信道”、“参数(parameter)”、“域”、“字段”、“符号(symbol)”、“码元(symbol)”、“码本(codebook)”、“码字(codeword)”、“码点(codepoint)”、“比特(bit)”、“数据(data)”、“程序(program)”、“码片(chip)”等术语可以相互替换。
步骤S2102，终端101基于第一参考信号资源进行测量。
在一些实施例中，终端101基于第一参考信号资源，对CSI-RS进行测量。
可选地，终端101基于第一参考信号资源，测量对应CSI-RS的到达时间。其中，CSI-RS的到达时间可以称为CSI-RS到达终端的时间，也可以是终端接收到CSI-RS的时间。应当理解，基于第一参考信号资源进行测量也可以被理解为针对第一参考信号资源进行测量。通过对参考信号资源进行测量，可以获取参考信号资源上的参考信号的到达时间，由于参考信号资源可以有多个，由此可以获得该多个参考信号资源上的参考信号的到达时间的差异，即到达时间差，该到达时间差可以用时间差异信息来表示。
在一些实施例中，终端101基于包括一个CMR的第一参考信号资源进行测量，其中一个CMR包括多个参考信号资源。
示例性的，终端101基于包括一个CMR的第一参考信号资源进行测量，其中一个CMR包括多个CSI-RS资源
步骤S2103，终端101确定第一信道状态信息。
在一些实施例中，终端101基于第一参考信号资源进行参考信号测量，确定第一信道状态信息。
可选地，终端101基于第一参考信号资源对CSI-RS进行测量，确定第一信道状态信息。
在一些实施例中，第一信道状态信息中包括时间差异信息。
可选地，时间差异信息指示不同参考信号资源上CSI-RS到达终端的时间差。
在一些实施例中，第一信道状态信息包含的内容可以由信道状态信息上报(CSI report config)配置信息配置得到，其中，信道状态信息上报配置信息由网络设备102发送至终端101。
可选地，终端101接收网络设备102发送的信道状态上报配置信息，其中，信道状态信息上报配置信息用于配置第一信道状态信息中包括时间差异信息。
在获取时间差异信息后，终端可以将时间差异信息告知网络设备。具体地，将时间差异信息上报给网络设备也可以根据网络设备下发的配置信息而执行，例如，网络设备可以向终端发送信道状态上报配置信息，终端根据信道状态上报配置信息来上报时间差异信息。
在一些实施例中，时间差异信息指示第二参考信号资源与第三参考信号资源上的参考信号到达终端的时间差。
可选地，第三参考信号资源为多个参考信号资源中的一个参考信号资源，第二参考信号资源为多个参考信号资源中不同于第三参考信号资源的其他参考信号资源。
在一些实施例中，在第一参考信号资源包括CMR，CMR包括多个参考信号资源的情况下，第三参考信号资源为CMR包括的多个参考信号资源中的一个参考信号资源。应当理解，终端设备上报的时间差异信息可以指示多个参考信号资源之间的差异，例如，时间差异可以是以多个参考信号资源中的某一个参考信号资源为基准，其他参考信号资源与该作为基准的参考信号资源之间的时间差异。
示例性的，第一参考信号资源包括CMR，CMR包括多个CSI-RS资源，第三参考信号资源为多个CSI-RS资源中的一个，例如，第一CSI-RS资源。
在一些实施例中，在第一参考信号资源包括CMR，CMR包括多个参考信号资源的情况下，第二参考信号资源为CMR包括的多个参考信号资源中除第三参考信号资源之外的一个参考信号资源。
示例性的，第一参考信号资源包括CMR，CMR包括多个CSI-RS资源，第三参考信号资源为多个CSI-RS资源中的一个，例如，第一CSI-RS资源。第二参考信号资源为多个CSI-RS资源中除第三参考信号资源之外的一个参考信号资源，例如，第二CSI-RS资源，第二CSI-RS资源与第一CSI-RS资源不同。
在一些实施例中，第三参考信号资源采用如下以下至少一种方式确定：
基于第一指示信息确定；
基于参考信号资源标识确定；
基于第一参考信号对应的参考信号资源确定。
即，作为基准的参考信号资源可以采用多种方式确定，可以由网络设备确定，也可以由终端自行确定。
在一些实施例中，基于第一指示信息确定，包括：基于第一指示信息，在多个参考信号资源中确定第三参考信号资源。
可选地，第一指示信息由网络设备102发送。第一指示信息用于指示第三参考信号资源。
示例性的，接续第一参考信号资源包括CMR，CMR包括多个CSI-RS资源的实施例，第一指示信息指示多个CSI-RS资源中的某一个资源为第三参考信号资源。例如，第一指示信息指示第一CSI-RS资源为第三参考信号资源。
在一些实施例中，基于参考信号资源标识确定，包括：基于参考信号资源标识的大小确定。
可选地，将多个参考信号资源中参考信号资源标识最小的参考信号资源，确定为第三参考信号资源。
示例性的，接续第一参考信号资源包括CMR，CMR包括多个CSI-RS资源的实施例，假定在多个CSI-RS资源中，标识最小的CSI-RS资源为第一CSI-RS资源，则确定第一CSI-RS资源为第三参考信号资源。
在一些实施例中，将第一参考信号对应的参考信号资源，确定为第三参考信号资源，其中，第 一参考信号为最早到达的CSI-RS。
可选地，第一参考信号由终端101测量得到。
示例性的，接续第一参考信号资源包括CMR，CMR包括多个CSI-RS资源的实施例，终端101测量得到最早到达终端101的CSI-RS，假定最早到达终端101的CSI-RS对应的CSI-RS资源为第一资源，则将第一资源确定为第三参考信号资源。
在一些实施例中，第一信道状态信息还包括第三参考信号资源标识。
示例性的，接续第一参考信号资源包括CMR，CMR包括多个CSI-RS资源的实施例，终端101测量得到最早到达终端101的CSI-RS，假定最早到达终端101的CSI-RS对应的CSI-RS资源为第一资源，则将第一资源确定为第三参考信号资源。则终端在上报时间差异时，需要上报第三参考信号资源标识。
在一些实施例中，第一信道状态信息还包括第二参考信号资源标识。
示例性的，终端确定第三参考信号资源之后，获得了第二参考信号资源上的参考信号与第三参考信号资源上的参考信号的时间差，则第一信道状态信息中还包括每个时间差对应的第二参考信号资源标识。
在一些实施例中，第二参考信号资源标识与时间差具有一一对应关系。
示例性的，接续上述实施例，终端确定第三参考信号资源之后，获得了第二参考信号资源上的参考信号与第三参考信号资源上的参考信号的时间差，由于第二参考信号资源为多个参考信号资源中除第三参考信号资源之外的参考信号资源，因此，每个第二参考信号资源都会与第三参考信号资源具有一一对应的时间差。因此，第二参考信号资源标识与时间差具有一一对应关系。
由此，可以得到，在一些实施例中，第三参考信号资源采用以下A-C中至少一种方式确定：
A.基于网络设备102发送的第一指示信息，在多个参考信号资源中确定所述第三参考信号资源，第一指示信息用于指示所述第三参考信号资源；
B.将多个参考信号资源中参考信号资源标识最小的参考信号资源，确定为第三参考信号资源；
C.将第一参考信号对应的参考信号资源，确定为第三参考信号资源，其中，所述第一参考信号为最早到达的信道状态信息参考信号。
在一些实施例中，所述时间差可以包括：不同CSI-RS对应时域位置之间的时间间隔，或不包括不同CSI-RS对应时域位置之间的时间间隔。
示例性的，对于时间差包括不同CSI-RS对应时域位置之间的时间间隔，可以被理解为：两个CSI-RS如CSI-RS#1和CSI-RS#2，对应的资源分别为CSI-RS#资源1和CSI-RS#资源2。CSI-RS#资源1的时域位置为slot#1的symbol#0，CSI-RS#资源2的时域位置为slot#2的symbol#0，假设终端测量得到CSI-RS#1的到达时间为t1，CSI-RS#2的到达时间为t2。
可以理解的是，t1时间为slot#1的symbol#0之后的一段时间，t2时间为slot#2的symbol#0之后的一段时间，所以时间差为t2-t1，而t2-t1这一段时间不仅包含了slot#2的symbol#0与slot#1的symbol#0之间的时间间隔，还包含了两个RS从各自TRP发送到UE之间的传输时间的差异。
示例性的，对于时间差不包括不同CSI-RS对应时域位置之间的时间间隔，可以被理解为：不考虑不同CSI-RS各自对应的CSI-RS资源所对应的slot位置以及symbol位置(或者认为不同CSI-RS对应的slot相同以及symbol相同)两个CSI-RS如CSI-RS#1和CSI-RS#2，对应的资源分别为CSI-RS#资源1和CSI-RS#资源2。CSI-RS#资源1的时域位置为slot#1的symbol#0，CSI-RS#资源2的时域位置为slot#2的symbol#0，假设终端测量得到CSI-RS#1的到达时间为t1，CSI-RS#2的到达时间为t2。
可以理解的是，t1时间为slot#1的symbol#0之后的一段时间，t2时间为slot#2的symbol#0之后的一段时间。所以t2-t1这一段时间不仅包含了slot#2的symbol#0与slot#1的symbol#0之间的时间间隔，还包含了两个RS从各自TRP发送到UE之间的传输时间的差异。如果时间差不包含不同CSI-RS对应时域位置之间的时间间隔，那么时间差为t2-t1再减去slot#2的symbol#0与slot#1的symbol#0之间的时间间隔后得到的值。
在一些实施例中，不同CSI-RS对应时域之间的时间间隔，可以是以下一项或多项：
不同CSI-RS对应的slot间隔；
不同CSI-RS对应的symbol间隔。
在一些实施例中，时间差的取值满足如下条件：大于或等于1个slot，和/或大于或等于1个symbol。
示例性的，时间差包含不同CSI-RS对应时域之间的时间间隔时，时间差可以大于或等于1个slot， 和/或大于或等于1个symbol。
在一些实施例中，时间差的取值小于一个symbol。
示例性的，时间差不包含不同CSI-RS对应时域之间的时间间隔时，时间差可以小于1个symbol。
在一些实施例中，时间差的取值可以为正数或负数。
示例性的，当第三参考信号资源上的参考信号不是最早到达的参考信号时，时间差可能为负值。
在一些实施例中，在时间差不包括不同CSI-RS对应时域位置之间的时间间隔的情况下，时间差的影响因素包括以下至少一项：
不同CSI-RS对应的TRP的位置；
不同CSI-RS对应的传播路径。
可以理解的是，处于不同位置的TRP的CSI-RS到达终端的时间是不同的。例如，TRP相对终端位置越远，对应CSI-RS到达终端的时间越晚。因此，时间差可以表示不同TRP的位置差异。
同样的，不同传播路径对应的CSI-RS达到终端的时间也是不同的。因此，时间差可以表示CSI-RS的不同传播路径。
需要说明的是，不同CSI-RS对应时域之间的时间间隔为0的情况下(例如，不同CSI-RS对应的时隙间隔为0，或者不同CSI-RS对应的符号间隔为0)，可以被看做时间差不包括不同CSI-RS对应时域位置之间的时间间隔的情况，采用上述方式表示时间差。
在一些实施例中，“时刻”、“时间点”、“时间”、“时间位置”等术语可以相互替换，“时长”、“时段”、“时间窗口”、“窗口”、“时间”等术语可以相互替换。
在一些实施例中，“帧(frame)”、“无线帧(radio frame)”、“子帧(subframe)”、“时隙(slot)”、“子时隙(sub-slot)”、“迷你时隙(mini-slot)”、“符号(symbol)”、“码元(symbol)”、“发送时间间隔(transmission time interval，TTI)”等术语可以相互替换。

基于循环前缀(cyclic prefix，CP)配置；或基于子载波间隔(Subcarrier Spacing，SCS)配置。
可选地，不同的SCS对应不同的第一映射关系。
可选地，不同的CP长度对应不同的第一映射关系。
示例性的，SCS为a KHz的情况下，码点#0对应的时间差值为1。基于此，可以得到SCS为a KHz与码点#0之间的第一映射关系，假定为“f(a)”。SCS为b KHz的情况下，码点#0对应的时间差值为2。基于此，可以得到SCS为b KHz与码点#0之间的第一映射关系，假定为“f(b)”，“a”与“b”不相等。由于相同的码点#0在不同的第一映射关系下，对应的时间差值不同，因此，“f(a)”与“f(b)”不同。也即，不同的SCS对应不同的第一映射关系。
可选地，可以定义SCS取值越大，则相同码点在SCS对应的第一映射关系下，得到的时间差值越小。
可以理解的是，对于不同的CP长度对应不同的第一映射关系，同样可查看上述SCS的示例列举，为避免重复赘述，此处不再列举。
