具体实施方式
为使本申请的目的、技术方案和优点更加清楚，下面将结合附图对本申请实施方式作进一步地详细描述。
本申请实施例描述的网络架构以及业务场景是为了更加清楚地说明本申请实施例的技术方案，并不构成对本申请实施例提供的技术方案的限定，本领域普通技术人员可知，随着网络架构的演变和新业务场景的出现，本申请实施例提供的技术方案对于类似的技术问题，同样适用。
首先，对本申请实施例中涉及的信道状态信息(CSI)等进行简单地介绍。
CSI是指用来估计通信链路的信道特性的信息。网络设备可以基于终端设备上报的CSI确定下行数据的调制方案、信道编码码率等，以提高下行数据的传输可靠性和传输效率。
在NR系统的Rel-15以及Rel-16中，CSI是基于终端设备对CSI-RS资源的测量获取并上报至网络设备的。在Rel-15和Rel-16中，CSI的上报依据时域特征划分为：周期性上报CSI、半持续性上报CSI、非周期性上报CSI。
周期性上报CSI：网络设备通过RRC(Radio Resource Control，无线资源控制)信令为终端设备配置上报CSI的周期和偏移，终端设备接收到该RRC信令之后，在网络设备配置的PUCCH(Physical Uplink Control Channel，物理上行控制信道)上周期性地上报CSI。
半持续性上报CSI：在终端设备通过PUCCH半持续性地上报CSI的情况下，网络设备通过MAC(Medium Access Control，媒体接入控制)CE(Control Element，控制单元)信令激活/去激活CSI的上报，在MAC CE信令激活CSI的上报后，终端设备在PUCCH上周期性地上报CSI；在终端设备通过PUSCH(Physical Uplink Shared Channel，物理上行共享信道)半持续性地上报CSI的情况下，网络设备通过DCI(Downlink Control Information，下行控制信息)激活/去激活CSI的上报，在DCI激活CSI的上报后，终端设备在PUSCH上周期性地上报CSI。
非周期性上报CSI：网络设备通过DCI触发CSI的上报，终端设备接收到该DCI之后，在该DCI指示的PUSCH上仅上报一次CSI。
在一些实现中，用于在slot n(时隙n)上报CSI的信道/干扰测量资源不能晚于CSI参考资源时隙n-n CSI-ref。对于周期性和半持续性地上报CSI，当只配置一个CSI-RS用于信道测量资源时，n CSI-ref需要大于
Figure PCTCN2021092852-appb-000001
对于非周期性地上报CSI，n CSI-ref需要大于CSI计算时间，其中，CSI计算时间远大于PDSCH解码时间。
为了同时满足URLLC业务的低时延与高可靠这两个特性(例如，保证URLLC业务在时延允许范围内的传输次数可以达到可靠性需求)，则需要终端设备上报更加准确的反映信道质量的信道状态信息，以辅助网络设备更好地进行初传和/或重传调度。在一个示例中，可以通过以下方式实现上报更为准确的信道状态信息。
(1)将周期性/半持续性地上报CSI的周期配置地非常短；
(2)使用DCI触发非周期地上报CSI。
针对方式(1)，需要网络设备高密度地发送CSI-RS资源，才能够获得快速更新的信道状态信息，这一方面加大了系统的参考信号(CSI-RS资源)开销，另一方面增加了终端设备的测量与计算开销。与此同时，由于受到CSI测量时间的影响，终端设备上报的CSI需要基于CSI参考资源之前的CSI-RS测量得到，对于在上行时隙n上报的周期性/半持续性CSI，CSI参考资源最早为时隙n-4传输的CSI-RS(假设：UL(Uplink，上行链路)和DL(Downlink，下行链路)具有相同的子载波间隔，且对信道测量只配置了一个CSI-RS资源)，而终端设备受到的干扰情况受到邻小区调度的影响很大，由于测量时间很长，终端设备在上报CSI时可能受到的干扰已经发生了变化，导致CSI不准确。
针对方式(2)，网络设备需要发送DCI来触发CSI-RS的发送以及CSI的上报，一方面，用于触发CSI上报的DCI只能是调度PUSCH的DCI(UL DCI)，而终端设备可能上下行业务不对称，并没有上行业务需求，这种情况下，为了触发CSI的上报，就会浪费UL DCI；另一方面，对于非周期性地上报CSI，终端设备从收到UL DCI到发送CSI的处理时间也很长，对于时延紧急的业务，如果初传错误，且时延需求无法容忍CSI上报，网络设备只能使用非常保守的MCS(Modulation and Coding Scheme，调制与编码策略)进行调度，导致系统的传输效率降低。
为满足URLLC业务的低时延与高可靠性的需求，且同时提升系统传输效率，Rel-17中提出了基于PDSCH的解调和/或测量的信道状态信息。基于PDSCH的解调和/或测量来获取信道状态信息不仅可以节约CSI-RS资源，还可以降低终端设备的计算功耗与处理时延，能够较好地满足URLLC业务的需求。
然而，针对基于PDSCH的解调和/或测量的信道状态信息是如何得到的，Rel-17中尚未提及和讨论。基于此，本申请实施例提供了一种信息报告方法，可用于解决上述技术问题。下面，将结合几个实施例对本申请的技术方案进行介绍说明。
需要说明的一点是，本申请实施例中所述的“终端设备向网络设备报告CSI”，又可以称为“终端设备向网络设备上报CSI”，还可以称为“终端设备向网络设备反馈CSI”。应理解，这些表述具有相同的含义， 可以彼此替换。
请参考图1，其示出了本申请一个实施例提供的通信系统的示意图。该通信系统可以包括：终端设备10和网络设备20。
终端设备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设备10。终端设备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设备。
网络设备20是一种部署在接入网中用以为终端设备10提供无线通信功能的装置。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(5th-Generation，第五代移动通信技术)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。为方便描述，本申请实施例中，上述为终端设备10提供无线通信功能的装置统称为网络设备。
可选地，网络设备20与终端设备10之间通过某种空口技术互相通信，例如Uu接口。
本申请实施例中的“5G NR系统”也可以称为5G系统或者NR系统，但本领域技术人员可以理解其含义。
应理解，本申请实施例的技术方案可以应用于各种通信系统，例如：长期演进(Long Term Evolution，LTE)系统、LTE频分双工(Frequency Division Duplex，FDD)系统、LTE时分双工(Time Division Duplex，TDD)系统、先进的长期演进(Advanced Long Term Evolution，LTE-A)系统、NR系统、NR系统的演进系统、非授权频段上的LTE(LTE-based access to Unlicensed spectrum，LTE-U)系统、NR-U(New Radio-Unlicensed，非授权频段上的NR)系统、无线局域网(Wireless Local Area Networks，WLAN)、无线保真(Wireless Fidelity，WiFi)、下一代通信系统或其他通信系统等。

步骤210，终端设备基于目标映射关系集合或者目标参考差值集合，确定第一差值对应的差分信道状态信息值。
差分信道状态信息值用于估计通信链路的信道质量和/或信道特征，可以辅助网络设备进行更好的链路自适应。本申请实施例对差分信道状态信息值的大小不作限定，可选地，差分信道状态信息值为1比特，或者2比特，或者为3比特，或者为4比特等。本申请实施例对差分信道状态信息值的表示形式也不作限定，可选地，差分信道状态信息值以二进制形式表示，或者以十进制形式表示，或者以十六进制形式表示等。
终端设备在确定了第一差值之后，基于目标映射关系集合或者目标参考差值集合，确定第一差值对应的差分信道状态信息值。应理解，“差分信道状态信息值”这一名称可能会发生变化，例如，“差分信道状态信息值”也可以称为“信道状态信息”，或者称为“新型信道状态信息”，或者称为“case-2 new reporting(情况2新型报告)”，或者称为“case-2 reporting(情况2报告)”。为便于描述，本申请实施例将基于目标映射关系集合或者目标参考差值集合确定的、可以辅助网络设备进行更好的链路自适应的信息，统称为“差分信道状态信息值”。
其中，目标映射关系集合包括至少一组参考差值与差分信道状态信息值之间的映射关系，该目标映射关系集合中的参考差值包括第一差值，从而终端设备可以从目标映射关系集合中，确定第一差值对应的差分信道状态信息值；目标参考差值集合包括至少一个参考差值，该至少一个参考差值包括第一差值，从而终端设备可以基于目标参考差值集合和第一差值，确定第一差值对应的差分信道状态信息值。可选地，目标映射关系集合中的参考差值为数值；或者，目标映射关系集合中的参考差值为差值范围。可选地，目标参考差值集合中的参考差值为数值；或者，目标参考差值集合中的参考差值为差值范围。
在一个示例中，目标参考差值集合中的参考差值基于其在目标参考差值集合中对应的位置，由通信协议定义或者由网络设备配置有相应的差分信道状态信息值，进而终端设备可以确定第一差值在目标参考差值集合中对应的位置，以进一步确定第一差值对应的差分信道状态信息值。可选地，网络设备通过高层信令为终端设备配置目标参考差值集合中不同的位置对应的差分信道状态信息值，该高层信令包括以下至少一项：SIB(System Information Block，系统消息块)、RRC、MAC。当然，目标参考差值集合中的参考差值对应的差分信道状态信息值还可以其它方式确定，例如，基于参考差值的大小由通信协议定义或者由网络设备配置有相应的差分信道状态信息值，应理解，这些确定方式均应属于本申请的保护范围之内。
本申请实施例对目标映射关系集合的表示形式不作限定，可选地，目标映射关系集合以映射表格的形式表示；或者，目标映射关系集合以树状图、图形等形式表示。本申请实施例对目标参考差值集合的表示形式也不作限定，可选地，目标参考差值集合以差值表格的形式表示；或者，目标参考差值集合以图形、 树状图等形式表示。在下述实施例的示例中，仅以目标映射关系集合以映射表格的形式表示、目标参考差值集合以差值表格的形式表示为例进行介绍说明，但这并不构成对本申请的限定。
示例性地，如下述表一所示，其示出了本申请一个实施例提供的目标映射关系集合，该目标映射关系集合包括四组参考差值与差分信道状态信息值之间的映射关系，假设第一差值为0，则第一差值对应的差分信道状态信息值为01；假设第一差值为-1，则第一差值对应的差分信道状态信息值为10。
表一 目标映射关系集合
差分信道状态信息值 参考差值
00 参考差值>0
01 参考差值＝0
10 参考差值＝-1
11 参考差值<-1
示例性地，如下述表二所示，其示出了本申请一个实施例提供的目标参考差值集合，该目标参考差值集合包括四个参考差值。假设基于参考差值在目标参考差值集合中从前至后的顺序，通信协议定义差分信道状态信息值分别为00、01、10、11。进一步假设第一差值为0，由于参考差值＝0在目标参考差值集合中位于第二位，则第一差值对应的差分信道状态信息值为01；进一步假设第一差值为-1，由于参考差值＝-1在目标参考差值集合中位于第三位，则第一差值对应的差分信道状态信息值为10。
表二 目标参考差值集合
参考差值
参考差值>0
参考差值＝0
参考差值＝-1
参考差值<-1
本申请实施例对第一差值的确定方式不作限定。在一个示例中，第一差值为目标MCS索引与PDSCH的MCS索引之间的差值；或者，第一差值为目标CQI(Channel Quality Indication，信道质量指示)索引与基于PDSCH确定的CQI索引之间的差值。在又一个示例中，第一差值为PDSCH的MCS索引与终端设备上一次确定的差分信道状态信息值之间的差值；或者，第一差值为基于PDSCH确定的CQI索引与终端设备上一次确定的差分信道状态信息值之间的差值。在还一个示例中，第一差值为基于PDSCH确定的CQI索引与终端设备最近一次向网络设备报告的信道状态信息中CQI索引之间的差值。有关终端设备确定第一差值的其它介绍说明，请参见下述方法实施例，此处不多赘述。
步骤220，终端设备向网络设备报告差分信道状态信息值。
终端设备在确定差分信道状态信息值之后，可以向网络设备报告该差分信道状态信息值，以辅助网络设备进行更好的链路自适应。本申请实施例对终端设备报告差分信道状态信息值的时机不作限定。在一个示例中，终端设备在确定出差分信道状态信息值之后，立即向网络设备报告差分信道状态信息值。在另一个示例中，终端设备在确定出差分信道状态信息值之后达到预设时间间隔后向网络设备报告差分信道状态信息值。在又一个示例中，终端设备在满足第一报告条件的情况下，向网络设备报告差分信道状态信息值，可选地，该第一报告条件包括：终端设备接收到特定的DCI、终端设备接收到的DCI中的某一DAI(Downlink Assignment Index，下行分配索引)满足特定的条件、终端设备所在的时间单元满足特定的条件等。本申请实施例对终端设备报告差分信道状态信息值的方式也不作限定，在一个示例中，终端设备将差分信道状态信息值作为单独的上行信息报告至网络设备；在另一个示例中，终端设备将第一信息与HARQ(Hybrid Automatic Repeat Request，混合自动重传请求)-ACK(Acknowledgement，肯定确认)信息组合在一起上报至网络设备。
综上所述，本申请实施例提供的技术方案，通过终端设备基于目标映射关系集合或者目标参考差值集合，确定第一差值对应的差分信道状态信息值，提供了一种确定报告至网络设备的信道状态信息的方式。由于目标映射关系集合包括至少一组参考差值与差分信道状态信息值之间的映射关系，从而终端设备基于目标映射关系集合可以快速且清楚地映射得到第一差值对应的差分信道状态信息值。由于目标参考差值集合包括至少一个参考差值，从而终端设备可以确定第一差值在目标参考差值集合中对应的参考差值，进而基于参考差值的属性信息(如在目标参考差值集合中的位置、参考差值的大小等)确定第一差值对应的差分信道状态信息值，另外，相比于目标映射关系集合，目标参考差值集合占用的物理空间更小，有助于降低终端设备的存储压力。
针对参考差值与差分信道状态信息值之间的映射关系，可以仅设置一个映射关系集合(即目标映射关系集合)，也可以设置多个映射关系集合，从而终端设备可以从多个映射关系集合中确定目标映射关系集 合。针对参考差值，可以仅设置一个参考差值集合(即目标参考差值集合)，也可以设置多个参考差值集合，从而终端设备可以从多个参考差值集合中确定目标参考差值集合。基于此，本申请实施例对目标映射关系集合和/或目标参考差值集合的确定方式并不作限定，下面示例性地对目标映射关系集合和/或目标参考差值集合的确定方式进行介绍说明。
在一种可能的实施方式中，如图3所示，上述步骤210之前还包括如下步骤中的至少部分步骤。
步骤202，网络设备向终端设备发送DCI，DCI中包括MCS索引。
网络设备向终端设备发送的DCI中可以包括MCS索引，基于该MCS索引，终端设备可以确定PDSCH的MCS，或者确定CQI等。
步骤204，终端设备基于MCS索引，从至少一个映射关系集合中确定目标映射关系集合，或者，从至少一个参考差值集合中确定目标参考差值集合。
本申请实施例中，终端设备基于MCS索引，还可以从至少一个映射关系集合中确定目标映射关系集合，或者从至少一个参考差值集合中确定目标参考差值集合。其中，至少一个映射关系集合中不同的映射关系集合对应于不同的MCS参考索引，该MCS参考索引包括DCI中包括的MCS索引，从而终端设备可以从至少一个映射关系集合中，确定与DCI中包括的MCS索引对应的映射关系集合(即目标映射关系集合)；至少一个参考差值集合中不同的参考差值集合对应于不同的MCS参考索引，该MCS参考索引包括DCI中包括的MCS索引，从而终端设备可以从至少一个参考差值集合中，确定与DCI中包括的MCS索引对应的参考差值集合(即目标参考差值集合)。可选地，MCS参考索引为MCS索引数值；或者，MCS参考索引为MCS索引范围。
在一个示例中，至少一个映射关系集合由通信协议定义，或者，至少一个映射关系集合由网络设备配置；至少一个参考差值集合由通信协议定义，或者，至少一个参考差值集合由网络设备配置。可选地，在由网络设备配置至少一个映射关系集合或者至少一个参考差值集合的情况下，网络设备可以通过高层信令配置至少一个映射关系集合或者至少一个参考差值集合，该高层信令包括以下至少一项：SIB、RRC、MAC。可选地，在通信协议定义至少一个映射关系集合时，可以同时定义至少一个映射关系集合对应的MCS参考索引；在通信协议定义至少一个参考差值集合时，可以同时定义至少一个参考差值集合对应的MCS参考索引；在网络设备配置至少一个映射关系集合时，可以同时配置至少一个映射关系集合对应的MCS参考索引；在网络设备配置至少一个参考差值集合时，可以同时配置至少一个参考差值集合对应的MCS参考索引。
应理解，在步骤204实现为终端设备基于MCS索引从至少一个映射关系集合中确定目标映射关系集合时，步骤210实现为终端设备基于目标映射关系集合确定第一差值对应的差分信道状态信息值；在步骤204实现为终端设备基于MCS索引从至少一个参考差值集合中确定目标参考差值集合时，步骤210实现为终端设备基于目标参考差值集合确定第一差值对应的差分信道状态信息值。
在一个示例中，至少一个映射关系集合包括第一映射关系集合，第一映射关系集合对应于MCS索引配置信息中除第一MCS参考索引和/或第二MCS参考索引之外的MCS参考索引；至少一个参考差值集合包括第一参考差值集合，第一参考差值集合对应于MCS索引配置信息中除第一MCS参考索引和/或第二MCS参考索引之外的MCS参考索引。
应理解，“MCS索引配置信息中除第一MCS参考索引和/或第二MCS参考索引之外的MCS参考索引”包括以下三种可选情况：“MCS索引配置信息中除第一MCS参考索引和第二MCS参考索引之外的MCS参考索引”、“MCS索引配置信息中除第一MCS参考索引之外的MCS参考索引”、“MCS索引配置信息中除第二MCS参考索引之外的MCS参考索引”。
第一MCS参考索引包括MCS索引配置信息中MCS索引数值最小的至少一个MCS参考索引；第二MCS参考索引包括MCS索引配置信息中MCS索引数值最大的至少一个MCS参考索引。在一个示例中，第一MCS参考索引由通信协议定义，或者，第一MCS参考索引由网络设备配置；第二MCS参考索引由通信协议定义，或者，第二MCS参考索引由网络设备配置。可选地，在由网络设备配置第一MCS参考索引和/或第二MCS参考索引的情况下，网络设备通过高层信令配置第一MCS参考索引和/或第二MCS参考索引，该高层信令包括以下至少一项：SIB、RRC、MAC。
其中，MCS索引配置信息是网络设备为终端设备配置的MCS参考索引相关的信息，可选地，MCS索引配置信息包括以下至少一项：MCS参考索引的索引数值、MCS参考索引对应的指示内容(如调制阶数、码率、频谱效率等)。可选地，在MCS索引配置信息包括MCS参考索引对应的指示内容的情况下，第二MCS参考索引不包括MCS索引配置信息中，对应的指示内容为保留(reserved)的MCS参考索引，和/或，第一MCS参考索引不包括MCS索引配置信息中，对应的指示内容为保留的MCS参考索引。
示例性地，如下述表三所示，其示出了本申请一个实施例提供的MCS索引配置信息。如表三所示，该MCS索引配置信息包括MCS参考索引以及MCS参考索引对应的指示内容(调制阶数、码率、频谱效 率)。
表三 MCS索引配置信息
Figure PCTCN2021092852-appb-000002
基于表三所示的MCS索引配置信息，假设第一MCS参考索引为MCS索引配置信息中MCS索引数值最小的1个参考索引，则第一MCS参考索引包括0；假设第一MCS参考索引为MCS索引配置信息中MCS索引数值最小的3个参考索引，则第一MCS参考索引包括0、1、2；假设第二MCS参考索引为MCS索引配置信息中MCS索引数值最大的1个参考索引，则第二MCS参考索引包括31；假设第二MCS参考索引为MCS索引配置信息中MCS索引数值最大的2个参考索引，则第二MCS参考索引包括31和30。
进一步地，假设第二MCS参考索引不包括MCS索引配置信息中对应的指示内容为保留的MCS参考索引，若第二MCS参考索引为MCS索引配置信息中MCS索引数值最大的1个参考索引，由于MCS参考索引29至31对应的指示内容为保留，则第二MCS参考索引包括28；若第二MCS参考索引为MCS索引配置信息中MCS索引数值最大的2个参考索引，由于MCS参考索引29至31对应的指示内容为保留，则第二MCS参考索引包括28和27。
由于第一映射关系集合和第一参考差值集合是对应于MCS索引配置信息中除第一MCS参考索引和/或第二MCS参考索引之外的参考索引，若需明确DCI中的MCS索引为第一MCS参考索引和/或第二MCS参考索引对应的映射关系集合或者参考差值集合，终端设备还需确定第一MCS参考索引和/或第二MCS参考索引对应的映射关系集合或者参考差值集合。基于此，在一个示例中，上述方法还包括：终端设备基于第一映射关系集合，确定第一MCS参考索引对应的映射关系集合，和/或，确定第二MCS参考索引对应的映射关系集合；终端设备基于第一参考差值集合，确定第一MCS参考索引对应的参考差值集合，和/或，确定第二MCS参考索引对应的参考差值集合。
在第一映射关系集合对应于MCS索引配置信息中除第一MCS参考索引之外的参考索引的情况下，终端设备基于第一映射关系集合，确定第一MCS参考索引对应的映射关系集合；在第一映射关系集合对应 于MCS索引配置信息中除第二MCS参考索引之外的参考索引的情况下，终端设备基于第一映射关系集合，确定第二MCS参考索引对应的映射关系集合；在第一映射关系集合对应于MCS索引配置信息中除第一MCS参考索引和第二MCS参考索引之外的参考索引的情况下，终端设备基于第一映射关系集合，确定第一MCS参考索引对应的映射关系集合和第二MCS参考索引对应的映射关系集合。
在第一参考差值集合对应于MCS索引配置信息中除第一MCS参考索引之外的参考索引的情况下，终端设备基于第一参考差值集合，确定第一MCS参考索引对应的参考差值集合；在第一参考差值集合对应于MCS索引配置信息中除第二MCS参考索引之外的参考索引的情况下，终端设备基于第一映射关系集合，确定第二MCS参考索引对应的参考差值集合；在第一参考差值集合对应于MCS索引配置信息中除第一MCS参考索引和第二MCS参考索引之外的参考索引的情况下，终端设备基于第一映射关系集合，确定第一MCS参考索引对应的参考差值集合和第二MCS参考索引对应的参考差值集合。
本申请实施例对终端设备确定第一MCS参考索引对应的映射关系集合和/或第二MCS参考索引对应的映射关系集合的方式不作限定。在一个示例中，终端设备删除或增加第一映射关系集合中的部分映射关系，得到第一MCS参考索引对应的映射关系集合和/或第二MCS参考索引对应的映射关系集合。在另一个示例中，终端设备将第一映射关系集合中第一映射关系替换为第二映射关系，得到第一MCS参考索引对应的映射关系集合；和/或，终端设备将第一映射关系集合中第三映射关系替换为第四映射关系，得到第二MCS参考索引对应的映射关系集合。
可选地，第一映射关系为参考差值为正数或者正数范围的映射关系；第二映射关系为参考差值为负数或者负数范围的映射关系；第三映射关系为参考差值为负数或者负数范围的映射关系；第四映射关系为参考差值为正数或者正数范围的映射关系。可选地，第一映射关系由通信协议定义，或者，第一映射关系由网络设备配置；第二映射关系由通信协议定义，或者，第二映射关系由网络设备配置；第三映射关系由通信协议定义，或者，第三映射关系由网络设备配置；第四映射关系由通信协议定义，或者，第四映射关系由网络设备配置。可选地，在由网络设备配置第一映射关系、第二映射关系、第三映射关系以及第四映射关系中的部分映射关系的情况下，网络设备通过高层信令配置，该高层信令包括以下至少一项：SIB、RRC、MAC。
本申请实施例对终端设备确定第一MCS参考索引对应的参考差值集合和/或第二MCS参考索引对应的参考差值集合的方式不作限定。在一个示例中，终端设备删除或增加第一参考差值集合中的部分参考差值，得到第一MCS参考索引对应的参考差值集合和/或第二MCS参考索引对应的参考差值集合。在另一个示例中，终端设备将第一参考差值集合中第一参考差值替换为第二参考差值，得到第一MCS参考索引对应的参考差值集合；和/或，终端设备将第一参考差值集合中第三参考差值替换为第四参考差值，得到第二MCS参考索引对应的参考差值集合。
可选地，第一参考差值为取值为正数或者正数范围的参考差值；第二参考差值为取值为负数或者负数范围的参考差值；第三参考差值为取值为负数或者负数范围的参考差值；第四参考差值为取值为正数或正数范围的参考差值。可选地，第一参考差值由通信协议定义，或者，第一参考差值由网络设备配置；第二参考差值由通信协议定义，或者，第二参考差值由网络设备配置；第三参考差值由通信协议定义，或者，第三参考差值由网络设备配置；第四参考差值由通信协议定义，或者，第四参考差值由网络设备配置。可选地，在由网络设备配置第一参考差值、第二参考差值、第三参考差值以及第四参考差值中的部分参考差值的情况下，网络设备通过高层信令配置，该高层信令包括以下至少一项：SIB、RRC、MAC。
综上所述，本申请实施例提供的技术方案，通过至少一个映射关系集合中不同的映射关系集合对应于不同的MCS参考索引，终端设备再基于DCI中包括的MCS索引从至少一个映射关系集合中确定目标映射关系集合，或者，通过至少一个参考差值集合中不同的参考差值集合对应于不同的MCS参考索引，终端设备再基于DCI中包括的MCS索引从至少一个参考差值集合中确定目标参考差值集合，可以实现在差分信道状态信息值同等量化比特的前提下，实现更高的信道状态信息报告精度。
并且，本申请实施例中，MCS参考索引为数值相比于MCS参考索引为MCS索引范围，可以实现更高的信道状态信息报告精度；MCS参考索引为索引范围相比于MCS参考索引为数值，可以降低通信协议开销或者降低网络设备与终端设备之间的信令开销。
另外，本申请实施例中，至少一个映射关系集合包括第一映射关系集合，至少一个参考差值集合包括第一参考差值集合，且第一映射关系集合或者第一参考差值集合对应于MCS索引配置信息中，除最大的至少一个MCS参考索引和/或最小的至少一个MCS参考索引之外的参考索引，从而大部分MCS参考索引与第一映射关系集合或者第一参考差值集合对应，只对最大的至少一个MCS参考索引和/或最小的至少一个MCS参考索引做特殊处理，实现了信道状态信息报告精度与通信协议开销或者信令开销之间达到较好的平衡。
由上述实施例可知，本申请实施例对第一差值的确定方式并不作限定，下面，示例性地介绍第一差值 的几种确定方式。
在一种可能的实施方式中，如图4所示，上述步骤210之前，还包括如下步骤中的至少部分步骤。
步骤20A，终端设备基于DCI确定第一信息。
本申请实施例中，第一信息为PDSCH的MCS索引，或者为CQI索引。终端设备基于网络设备发送的DCI确定第一信息。在一个示例中，DCI中包括MCS索引；上述步骤20A包括：终端设备基于DCI中包括的MCS索引，确定第一信息。下面，针对第一信息为PDSCH的MCS索引时、第一信息为CQI索引时，第一信息的确定方式分别介绍说明。
首先，假设第一信息为PDSCH的MCS索引。
在一个示例中，上述终端设备基于DCI中包括的MCS索引，确定第一信息，包括：终端设备将DCI中包括的MCS索引，确定为PDSCH的MCS索引。也即，终端设备直接将DCI中包括的MCS索引作为PDSCH的MCS索引。
由上述表三可知，MCS参考索引对应的指示内容可能为保留，考虑到这一因素，可选地，终端设备在DCI中包括的MCS索引对应的指示内容不是保留的情况下，将DCI中包括的MCS索引，确定为PDSCH的MCS索引。
基于此，可选地，上述方法还包括：终端设备在DCI中包括的MCS索引对应的指示内容是保留的情况下，基于假设的TBS(Transport Block Size，传输块大小)、DCI中包括的MCS索引对应的调制阶数以及DCI中包括的时频资源指示信息，确定第一指示内容；终端设备将第二指示内容对应的MCS索引，确定为PDSCH的MCS索引。其中，第二指示内容是MCS索引配置信息中与第一指示内容最接近的指示内容。可选地，上述指示内容包括码率和/或频谱效率。示例性地，在第一指示内容包括码率的情况下，第二指示内容也包括码率；在第一指示内容包括频谱效率的情况下，第二指示内容也包括频谱效率；在第一指示内容包括码率和频谱效率的情况下，第二指示内容也包括码率和频谱效率。可选地，在第一指示内容包括码率和频谱效率的情况下，第二指示内容是MCS索引配置信息中与第一指示内容包括的码率最接近的指示内容，且第二指示内容包括码率和频谱效率；或者，第二指示内容是MCS索引配置信息中与第一指示内容包括的频谱效率最接近的指示内容，且第二指示内容包括码率和频谱效率。
在一个示例中，第二指示内容是MCS索引配置信息中大于或等于第一指示内容的指示内容中，与第一指示内容最接近的指示内容。在另一个示例中，第二指示内容是MCS索引配置信息中小于或等于第一指示内容的指示内容中，与第一指示内容最接近的指示内容。在又一个示例中，第二指示内容是MCS索引配置信息中第一MCS索引范围对应的指示内容中，与第一指示内容最接近的指示内容。在再一个示例中，第二指示内容是MCS索引配置信息中第一MCS索引范围对应的指示内容中，大于或等于第一指示内容的指示内容中与第一指示内容最接近的指示内容。在还一个示例中，第二指示内容是MCS索引配置信息中第一MCS索引范围对应的指示内容中，小于或等于第一指示内容的指示内容中与第一指示内容最接近的指示内容。
本申请实施例对第一MCS索引范围的确定方式不作限定，可选地，第一MCS索引范围由通信协议定义，或者由网络设备配置，或者由终端设备基于第一条件确定。可选地，该第一条件包括：第一MCS索引范围中的MCS参考索引对应的调制阶数，与DCI中包括的MCS索引对应的调制阶数相同。可选地，在第一MCS索引范围由网络设备配置的情况下，网络设备通过高层信令配置，该高层信令包括以下至少一项：SIB、RRC、MAC。
示例性地，假设DCI中包括的MCS索引为29，基于上述表三可知，DCI中包括的MCS索引为保留，进而终端设备基于假设的TBS、DCI中包括的MCS索引对应的调制阶数、DCI中包括的时频资源指示信息，确定出第一码率或第一频率效率。进一步地，基于上述表三可知，DCI中包括的MCS索引对应的调制阶数为2，基于上述表三，可以确定第一MCS索引范围为MCS索引为0至9。接着，终端设备可以从MCS索引为0至9对应的指示内容中确定与第一码率或第一频谱效率最接近的码率或频谱效率，并确定其对应的MCS索引，该MCS索引即为PDSCH的MCS索引。
其次，假设第一信息为CQI索引。
在一个示例中，上述终端设备基于DCI中包括的MCS索引，确定第一信息，包括：终端设备基于DCI中包括的MCS索引，确定第三指示内容；终端设备将第四指示内容对应的CQI索引，确定为CQI索引，第四指示内容是CQI索引配置信息中与第三指示内容最接近的指示内容。可选地，上述指示内容包括码率和/或频谱效率。示例性地，在第三指示内容包括码率的情况下，第四指示内容也包括码率；在第三指示内容包括频谱效率的情况下，第四指示内容也包括频谱效率；在第三指示内容包括码率和频谱效率的情况下，第四指示内容也包括码率和频谱效率。可选地，在第三指示内容包括码率和频谱效率的情况下，第四指示内容是CQI索引配置信息中与第三指示内容包括的码率最接近的指示内容，且第四指示内容包括码率和频谱效率；或者，第四指示内容是CQI索引配置信息中与第三指示内容包括的频谱效率最接近的指示内容， 且第四指示内容包括码率和频谱效率。
在本示例中，CQI索引配置信息包括CQI索引以及CQI索引对应的指示内容。终端设备先基于MCS索引配置信息，确定DCI中包括的MCS索引对应的指示内容(即第三指示内容)；再基于CQI索引配置信息，确定与第三指示内容最接近的第四指示内容，然后将第四指示内容对应的CQI索引，确定为作为第一信息的CQI索引。在一个示例中，第四指示内容是CQI索引配置信息中大于或等于第三指示内容的指示内容中，与第三指示内容最接近的指示内容。在另一个示例中，第四指示内容是CQI索引配置信息中小于或等于第三指示内容的指示内容中，与第三指示内容最接近的指示内容。在又一个示例中，第四指示内容是CQI索引配置信息中第一CQI索引范围对应的指示内容中，与第三指示内容最接近的指示内容。在再一个示例中，第四指示内容是CQI索引配置信息中第一CQI索引范围对应的指示内容中，大于或等于第三指示内容的指示内容中与第三指示内容最接近的指示内容。在还一个示例中，第四指示内容是CQI索引配置信息中第一CQI索引范围对应的指示内容中，小于或等于第三指示内容的指示内容中与第三指示内容最接近的指示内容。
本申请实施例对第一CQI索引范围的确定方式不作限定，可选地，第一CQI索引范围由通信协议定义，或者由网络设备配置，或者由终端设备基于第二条件确定。可选地，该第二条件包括：第一CQI索引范围中的CQI参考索引对应的调制阶数，与DCI中包括的MCS索引对应的调制阶数相同。可选地，在第一CQI索引范围由网络设备配置的情况下，网络设备通过高层信令配置，该高层信令包括以下至少一项：SIB、RRC、MAC。
步骤20C，终端设备基于PDSCH确定第二信息。
本申请实施例中，第二信息为目标MCS索引，或者为目标CQI索引。终端设备可以基于PDSCH确定第二信息。其中，PDSCH为DCI调度的PDSCH或者SPS(Semi-Persistent Scheduling，半静态调度)PDSCH。在一个示例中，上述步骤20B，包括：终端设备基于对PDSCH的解调和/或测量，得到第二信息。可选地，终端设备基于对PDSCH的解调所使用的DMRS(Demodulation-Reference Signal，解调参考信号)，得到第二信息。
步骤20E，终端设备确定第一差值，第一差值为第二信息与第一信息之间的差值。
通过上述步骤20A和步骤20C，终端设备分别计算出第一信息和第二信息，之后终端设备将第二信息与第一信息之间的差值作为第一差值。可选地，第二信息与第一信息之间的差值既可以为第二信息减去第一信息，也可以为第一信息减去第二信息，本申请实施例对此不作限定。在一个示例中，第一信息为PDSCH的MCS索引，第二信息为目标MCS索引，则第一差值为目标MCS索引与PDSCH的MCS索引之间的差值，可以称为delta-MCS。在另一个示例中，第一信息为CQI索引，第二信息为目标CQI索引，则第一差值为目标CQI索引与CQI索引之间的差值，可以称为delta-CQI。
综上所述，本申请实施例提供的技术方案，通过基于DCI确定第一信息、基于PDSCH确定第二信息，再将第二信息与第一信息之间的差值作为第一差值，提供了一种计算第一差值的方式。并且，本申请实施例中，第一差值既可以为基于PDSCH确定的MCS索引与基于DCI确定的MCS索引之间的差值，也可以为基于PDSCH确定的CQI索引与基于DCI确定的CQI索引之间的差值，提升了第一差值确定方式的灵活性。
下面，以几个示例对本申请实施例提供的技术方案进行介绍说明。
在一个示例中，假设网络设备通过高层信令为终端设备配置了三个映射关系集合，分别为下述表四、表五、表六，假设表四所示的映射关系集合对应于除最高的MCS参考索引和最低的MCS参考索引之外的参考索引、表五所示的映射关系集合对应于最低的MCS参考索引、表六所示的映射关系集合对应于最高的MCS参考索引。

假设终端设备接收到来自于网络设备的DCI，该DCI中包括的MCS索引为0，则终端设备将DCI中包括的MCS索引作为PDSCH的MCS索引，即PDSCH的MCS索引为0。基于上述表三所示的MCS索引配置信息，可以得到MCS索引为0是最低的MCS参考索引，因此，终端设备使用上述表五所示的映射关系集合确定差分信道状态信息值。假设终端设备基于PDSCH的解调和/或测量得到的目标MCS索引为2，则第一差值为2，从而基于上述表五，可以得知第一差值对应的差分信道状态信息值为10。
在另一个示例中，假设网络设备通过高层信令为终端设备配置了三个映射关系集合，分别为下述表七、表八、表九，假设表七所示的映射关系集合对应于MCS索引范围1(MCS索引为3至25)、表八所示的映射关系集合对应于MCS索引范围2(MCS索引为0至2)、表九所示的映射关系集合对应于MCS索引范围3(MCS索引为26至28)。

00 参考差值≥0

假设终端设备接收到来自于网络设备的DCI，该DCI中包括的MCS索引为5，则终端设备将DCI中包括的MCS索引作为PDSCH的MCS索引，即PDSCH的MCS索引为5，属于MCS索引范围1，因此，终端设备使用上述表七所示的映射关系集合确定差分信道状态信息值。假设终端设备基于PDSCH的解调和/或测量得到的目标MCS索引为6，则第一差值为1，从而基于上述表七，可以得知第一差值对应的差分信道状态信息值为01。
