请参考图1，其示出了本公开实施例提供的一种无线通信系统的结构示意图。如图1所示，无线通信系统是基于蜂窝移动通信技术的通信系统，该无线通信系统可以包括：若干个终端11以及若干个接入设备12。
其中，终端11可以是指向用户提供语音和/或数据连通性的设备。终端11可以经无线接入网(Radio Access Network，RAN)与一个或多个核心网进行通信，终端11可以是物联网终端，如传感器设备、移动电话(或称为“蜂窝”电话)和具有物联网终端的计算机，例如，可以是固定式、便携式、袖珍式、手持式、计算机内置的或者车载的装置。例如，站(Station，STA)、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、远程终端(remote terminal)、接入终端(access terminal)、用户装置(user terminal)、用户代理(user agent)、用户设备(user device)、或用户终端(user equipment，终端)。或者，终端11也可以是无人飞行器的设备。或者，终端11也可以是车载设备，比如，可以是具有无线通信功能的行车电脑，或者是外接行车电脑的无线通信设备。或者，终端11也可以是路边设备，比如，可以是具有无线通信功能的路灯、信号灯或者其它路边设备等。

其中，接入设备12可以是4G系统中采用的演进型接入设备(eNB)。或者，接入设备12也可以是5G系统中采用集中分布式架构的接入设备(gNB)。当接入设备12采用集中分布式架构时，通常包括集中单元(central unit，CU)和至少两个分布单元(distributed unit，DU)。集中单元中设置有分组数据汇聚协议(Packet Data Convergence Protocol，PDCP)层、无线链路层控制协议(Radio Link Control，RLC)层、媒体访问控制(Media Access Control，MAC)层的协议栈；分布单元中设置有物理(Physical，PHY)层协议栈，本公开实施例对接入设备12的具体实现方式不加以限定。
接入设备12和终端11之间可以通过无线空口建立无线连接。在不同的实施方式中，该无线空口是基于第四代移动通信网络技术(4G)标准的无线空口；或者，该无线空口是基于第五代移动通信网络技术(5G)标准的无线空口，比如该无线空口是新空口；或者，该无线空口也可以是基于5G的更下一代移动通信网络技术标准的无线空口。
可选的，上述无线通信系统还可以包含网络管理设备13。若干个接入设备12分别与网络管理设备13相连。其中，网络管理设备13可以是无线通信系统中的核心网设备，比如，该网络管理设备13可以是演进的数据分组核心网(Evolved Packet Core，EPC)中的移动性管理实体(Mobility  Management Entity，MME)。或者，该网络管理设备也可以是其它的核心网设备，比如服务网关(Serving GateWay，SGW)、公用数据网网关(Public Data Network GateWay，PGW)、策略与计费规则功能单元(Policy and Charging Rules Function，PCRF)或者归属签约用户服务器(Home Subscriber Server，HSS)等。对于网络管理设备13的实现形态，本公开实施例不做限定。
如图2所示，本公开实施例提供一种CSI的处理方法，由终端执行，包括：
S110：基于CSI预测结果，执行RS的测量和/或CSI的上报。
在本公开实施例中，CSI为信道状态信息，可以指示终端与基站之间通信链路的信道属性。例如，CSI可包括：信道质量指示(channel quality indicator，CQI)、秩指示(rank indicator，RI)和预编码指示(Precoder matrix indicator，PMI)中的至少之一。
RS为用于测量获取CSI的参考信号，例如，RS可以为基站下发的CSI资源配置信息(CSI Resource Configuration)中携带的。其中，CSI资源配置信息可以包含在基站下发的CSI上报配置信息中。CSI上报配置信息可用于指示终端进行CSI测量和CSI上报所需的资源信息。例如，CSI资源配置信息和CSI上报配置信息可以由无线资源控制(Radio Resource Control，RRC)信令等携带下发给终端。
示例性的，RS可以为信道状态信息参考信号(Channel Status Information-Reference Signal，CSI-RS)，或者，RS也可以为同步信号块(Synchronization Signal Block，SSB)等。
在一个实施例中，RS测量可包括：周期性测量和非周期性测。其中，周期性测量可以包括基于基站指示的周期进行的周期性测量，也可以包括基于基站下发的激活指令和去激活指令开始和结束的半静态测量。非周期性测量可以为基于基站下发的指示信息执行一次测量。
在一个实施例中，CSI上报可包括：周期性上报和非周期性上报。其中，周期性上报可以包括基于基站指示的周期进行的周期性上报，也可以包括基于基站下发的激活指令和去激活指令开始和结束的半静态上报。非周期性上报可以为基于基站下发的指示信息执行一次上报。
在一个实施例中，CSI预测结果，可以包括以下至少之一：对一个或多个目标时刻预测的CSI结果、对目标时间段预测的CSI结果、对一个或多个目标时刻预测的CSI时域预测情况以及对目标时间段预测的CSI时域预测情况。
其中，目标时刻或目标时间段，可以为基站配置指示的或者是由终端自行确定的，例如是由终端根据当前时刻和/或终端与基站间的预定协议确定的。对一个或多个目标时刻或目标时间段预测的CSI结果，可以基于当前测量得到的CSI和/或当前时刻之前的预设时间窗内测量得到过的CSI进行预测的。例如，可以基于预设的人工智能(Artificial Intelligence，AI)模型进行预测等。
示例性的，如图3所示，基于CSI预测模型(CSI prediction model)对历史多个时刻t 0、t 1、…t k测量得到的多个CSI：CSI t 0、CSI t 1、…CSI t k等进行处理，得到对未来的一个目标时刻t N预测的CSI t N。
在一个实施例中，对一个或多个目标时刻或目标时间段预测的CSI，还可以为基于当前测量得 到的CSI和/或当前时刻之前的预设时间窗内测量得到过的CSI，以及终端当前状态信息和/或信息进行预测的。
在一个实施例中，CSI时域预测情况，可以包括以下至少之一：
CSI随时间的变化情况、RS的建议测量周期以及CSI的建议上报周期等。CSI时域变化情况中的CSI可以为当前RS测量得到的CSI，也可以为一个或多个目标时刻或目标时间段预测的CSI结果等。
在一个实施例中，CSI随时间的变化情况，可以包括预设时段内的CSI变化速率。其中，预设时段可以为固定值，或者，也可以为预测CSI变化幅度达到预设值时对应的时间段。
示例性的，预设时段内的CSI变化速率，可包括：若当前RS测量得到的CQI为3级，当预测变化幅度达到5级即预测到RS测量得到CQI为8级时，当前时刻到预测到RS测量得到CQI为8级的时刻之间CQI的变化速率。
在一个实施例中，CSI预测结果还可以包括：预测的RS测量频率和/或CSI上报频率，或者，预测的单次RS测量结果的有效时长和/或单次CSI上报结果的有效时长等。
在一个实施例中，RS的测量，可以为基于RS进行信道状态的测量，得到RS对应的CSI。CSI的上报，可以为将当前RS测量得到的CSI上报给基站。
在一个实施例中，CSI预测结果还可以包括：目标时刻上报的CSI的有效时长。其中，目标时刻可以为当前时刻或者当前时刻之后的一个时刻。有效时长可以表示该目标时刻上报的CSI可以持续指示信道状态的时长，其中，有效时长可以用具体的时长或者时间单位个数表示。例如，有效时长为10s时，可以表示从目标时刻起的10s内，在目标时刻上报的CSI可指示该10s内的信道状态。
例如，时间单位可以为时隙(slot)。有效时长为100slot时，可以表示从目标时刻起的100slot内，在目标时刻上报的CSI可指示该100slot内的信道状态。
在一个实施例中，有效时长还可以用RRC提前配置的有效时长标识(Identity Document，ID)用来指示，例如ID#1表示50slot，ID#2表示100slot，ID#3表示200slot等。
示例性的，终端通过上报ID#2来指示有效时长为100slot。
在一个实施例中，CSI预测结果可以为终端自行预测得到的，也可以为接收的基站预测得到的CSI预测结果。例如，步骤S110可包括：基于基站发送的CSI预测结果指示的RS测量周期执行RS测量，和/或基于基站发送的CSI预测结果指示的CSI上报周期执行CSI上报。
其中，RS的建议测量周期和/或CSI的建议上报周期，可以由CSI预测结果直接指示，也可以为基于CSI预测结果指示的有效时长确定。例如，RS的建议测量周期和/或CSI的建议上报周期，可以等于有效时长，或者，也可以小于有效时长，或者，可以与有效时长具备预设关系。
示例性的，有效时长为10s时，RS的建议测量周期和/或CSI的建议上报周期可以为10s，也可以为8s或有效时长的1/2即5s等。
在一个实施例中，RS的建议测量周期和/或CSI的建议上报周期，还可以用时隙(slot)数量表示，例如RS的建议测量周期和/或CSI的建议上报周期可以为5slot或10slot等。
在一个实施例中，根据终端上报的有效时长，在一次上报CSI后的有效时长内通过用于传输RS和/或上报CSI的时频资源执行当前终端或者其他终端的数据传输。终端在一次上报CSI后的有效时长内，可以忽略RS的至少部分周期性测量和/或CSI的至少部分周期性上报。
示例性的，第一CSI上报配置信息(CSI Report Config#1)指示的CSI上报周期为40slot，分别在第11slot、第51slot和第91slot进行CSI上报。第二CSI上报配置信息(CSI Report Config#2)指示的CSI上报周期为80slot，分别在第11slot和第91slot进行CSI上报。CSI预测结果中的有效时长为100slot时，可以忽略CSI Report Config#1对应的CSI上报周期中第11slot和第51slot的CSI上报。
在一个实施例中，终端在有效时长内接收到基站下发的非周期性CSI上报指令，则进行非周期性CSI上报。
示例性的，终端在第1slot上报了有效时长为100slot，并在第81slot接收到基站下发的非周期性CSI上报指令，则可以按照基站指示仍然上报CSI，例如可以在第85slot上报CSI，而且上报的CSI中包含CSI预测结果。
在一个实施例中，步骤S110还可以包括：将CSI预测结果发送给基站；基于基站根据CSI预测结果指示的RS的建议测量周期和/或CSI的建议上报周期，执行RS的测量和/或CSI的上报。例如，CSI预测结果可以指示有效时长，则可以基于基站基于有效时长确定的RS的建议测量周期和/或CSI的建议上报周期，执行RS的测量和/或CSI的上报。
再例如，CSI预测结果可以指示基于有效时长确定的RS的建议测量周期和/或CSI的建议上报周期，则可以在接收到基站指示认可RS的建议测量周期和/或CSI的建议上报周期的预设指令后，基于该RS的建议测量周期和/或CSI的建议上报周期，执行RS的测量和/或CSI的上报。
在一个实施例中，步骤S110还可以包括：将CSI预测结果发送给基站；在发送给基站后，基于CSI预测结果，执行RS的测量和/或CSI的上报。
在一个实施例中，RS的建议测量周期和/或CSI的建议上报周期，可以为终端基于有效时长确定的，也可以为终端在基站指示的多个备选RS测量周期和/或多个备选CSI上报周期中，基于有效时长确定的。例如，可以基于与有效时长相同或差值最低的备选RS测量周期和/或备选CSI上报周期，执行RS的测量和/或CSI的上报。
因此，结合CSI的有效时长确定RS的建议周期和/或CSI的建议上报周期，可以减少RS的建议测量周期和/或CSI的建议上报周期配置不当导致过于频繁地产生不必要的RS测量和/或CSI上报，进而降低资源开销和功耗。
示例性的，基站指示的备选CSI上报周期包括5s、8s和10s，当有效时长为10s时，可以选择10s的备选CSI上报周期为CSI的建议上报周期。
示例性的，基站预先通过RRC向终端发送的资源配置信息中，指示了备选RS周期和/或备选CSI上报周期包括：第一索引值index#1表征RS周期和/或CSI上报周期为5个slot，第二索引值index#2表征RS周期和/或CSI上报周期为10个slot。若终端基于有效时长选择RS的建议周期和/ 或CSI的建议上报周期为10s，则可以向基站发送第二索引值，从而减少上报数据量，利于基站获知终端选择的周期值。
如此，通过对未来时刻的CSI进行预测，基于CSI预测结果确定的RS测量行为以及CSI上报行为，可以更加匹配CSI的预测变化情况，从而可以随CSI的预测结果变化灵活调整RS测量及CSI上报的行为，例如调整操作周期或频率等。因此，可以提高终端执行RS测量操作和CSI上报操作的灵活性，减少对测量操作和上报操作控制准确性低导致操作产生较高的资源开销和功耗浪费。
在一些实施例中，CSI预测结果，包括以下至少之一：
在目标时刻上报的CSI的有效时长；
RS的建议测量周期；
CSI的建议上报周期。
这里，目标时刻可以为下一次上报CSI的时刻，或者也可以为当前已完成的上报CSI的时刻。例如可以为根据当前时刻、当前时刻之前最后一次上报CSI的时刻以及CSI预测结果中的CSI上报周期中的至少一个，确定的下一次上报CSI的时刻。
在一个实施例中，在目标时刻上报的CSI的有效时长，可以根据当前时刻上报的CSI或者当前时刻之前最后一次上报的CSI确定。例如，可以根据当前时刻之前最后一次上报的CSI预测目标时刻的CSI，并基于预测的目标时刻的CSI确定在目标时刻上报的CSI的有效时长。
在一个实施例中，在目标时刻上报的CSI的有效时长，还可以根据当前时刻之前多个历史上报的CSI预测目标时刻的CSI，并基于预测的目标时刻的CSI确定在目标时刻上报的CSI的有效时长。
如图4所示，本公开实施例提供一种CSI的处理方法，由终端执行，包括：
S111：基于CSI预测结果，执行RS的测量和/或CSI的上报；CSI预测结果，包括以下至少之一：目标时刻上报的CSI的有效时长；RS的建议测量周期；CSI的建议上报周期；
S120：在目标时刻上报的CSI的有效时长内，停止RS的至少部分周期性测量和/或CSI的至少部分周期性上报。
在本公开实施例中，有效时长可作为CSI上报的一个上报量(report quantity)，即由终端上报给基站。在达到目标时刻执行CSI上报后的有效时长内，该上报的CSI可以被认为持续表征信道状态，则在该有效时长内无需继续测量RS和/或上报CSI。
在一个实施例中，在目标时刻上报的CSI的有效时长内，停止RS的至少部分周期性测量和/或CSI的至少部分周期性上报，可以为：在目标时刻上报的CSI的至少部分有效时长内，停止RS的至少部分周期性测量和/或CSI的至少部分周期性上报。
在一个实施例中，停止RS的至少部分周期性测量和/或CSI的至少部分周期性上报，可包括：停止有效时长内除最后一次RS测量时刻和/或CSI上报时刻之外其他时刻的周期性测量和/或周期性上报。
这里，终端在基于目标时刻的有效时长内最后一次CSI周期性上报时刻和/或RS测量时刻，进 行CSI上报/RS测量。
在另一个实施例中，停止RS的至少部分周期性测量和/或CSI的至少部分周期性上报，可包括：停止基于目标时刻的有效时长内所有周期性CSI上报和/或所有周期性RS测量，直至有效时长内接收到基站下发的指示CSI上报的指示信息时，进行CSI上报和/或RS测量。
这里，指示信息可以是包含非周期性CSI上报指令的下行控制信息(Downlink Control Information，DCI)。
在一个实施例中，方法还可包括：
在目标时刻上报的CSI的有效时长内，基于基站的指示信息上报CSI。
在本公开实施例中，在有效时长内仍然执行基站通过指示信息指示的上报和/或测量。若接收到基站的指示信息，则基于指示信息获取RS，并执行RS的测量以及CSI的上报。
其中，基于指示信息获取RS，可以为获取指示信息所指示的RS，或者基于指示信息向基站请求获取RS等。指示信息可以为基站下发的DCI，例如指示信息可用于指示终端上报CSI。
在一个实施例中，方法还可包括：在目标时刻上报的CSI的有效时长内，若接收到基站指示测量RS的指示信息，则执行RS的测量。
在一个实施例中，若基于有效时长确定RS的建议测量周期，当RS的建议测量周期大于或等于有效时长时，则可以在基于目标时刻上报CSI后的一个建议测量周期内或一个有效时长内，若接收到基站指示测量RS的指示信息，则执行RS的测量。
在一个实施例中，若基于有效时长确定RS的建议测量周期，当RS的建议测量周期小于有效时长时，则可以在基于目标时刻上报CSI后的一个建议测量周期内，若接收到基站指示测量RS的指示信息，则执行RS的测量。
在一个实施例中，若基于有效时长确定CSI的建议上报周期，当CSI的建议上报周期大于或等于有效时长时，则在基于目标时刻上报CSI后的一个建议上报周期内或一个有效时长内，若接收到基站指示上报CSI的指示信息，则执行CSI的上报。
在一个实施例中，若基于有效时长确定CSI的建议上报周期，当CSI的建议上报周期小于有效时长时，则可以在基于目标时刻上报CSI后的一个建议上报周期内，若接收到基站指示上报CSI的指示信息，则执行CSI的上报。
如此，在有效时长内屏蔽周期性CSI上报，但依然可以响应基于基站指示的非周期性CSI上报，从而在降低非必要的周期性上报的基础上，保持对基站获取CSI指令的响应，减少基站无法在需要时获取CSI的情况。
如图5所示，本公开实施例提供一种CSI的处理方法，由终端执行，包括：
S111：基于CSI预测结果，执行RS的测量和/或CSI的上报；CSI预测结果包括：目标时刻上报的CSI的有效时长；
S121：在目标时刻上报的CSI的至少部分有效时长内，若接收到基站基于有效时长下发的指示 CSI非周期性上报的指示信息，则执行CSI非周期性上报和/或RS非周期性测量。
这里，指示信息可以是包含非周期性CSI上报指令的DCI。若接收到指示信息执行的CSI非周期性上报，可以为上报CSI，也可以为上报CSI以及CSI预测结果。
在本公开实施例中，基站基于有效时长下发的指示信息，可以为基站在基于有效时长确定的下发时刻下发的指示信息。例如，下发时刻与当前时刻或者当前时刻之前最后一次CSI上报时刻间的时间间隔，可以小于或等于有效时长。
在一个实施例中，基站基于有效时长下发的指示信息，还可以为基站下发的指示基于有效时长确定的待上报CSI时刻的指示信息。例如，待上报CSI时刻与当前时刻或者当前时刻之前最后一次CSI上报时刻间的时间间隔，可以小于或等于有效时长。
示例性的，基站在第1slot上报CSI以及CSI有效时长10slot，则基站可以在第9slot下发指示信息，指示终端执行一次非周期性CSI上报。
在一个实施例中，RS的周期性测量可以包括RS持续的周期性测量，例如基于基站配置的测量周期持续进行的RS周期性测量，或者，RS的周期性测量也可以包括RS的半静态测量，例如半静态测量可以为基于基站指示的开始指令开始RS周期性测量，并基于基站指示的结束指令停止RS周期性测量。
在一个实施例中，CSI的周期性上报可以包括CSI持续的周期性上报，例如基于基站配置的上报周期持续进行的CSI周期性上报，或者，CSI的周期性上报也可以包括CSI的半静态上报，例如半静态上报可以为基于基站指示的开始指令开始CSI周期性上报，并基于基站指示的结束指令停止CSI周期性上报。
在一个实施例中，若基于有效时长确定RS的建议测量周期，当RS的建议测量周期大于或等于有效时长时，则可以在基于目标时刻上报CSI后的一个建议测量周期内或一个有效时长内，停止RS的周期性测量。
在一个实施例中，若基于有效时长确定RS的建议测量周期，当RS的建议测量周期小于有效时长时，则可以在基于目标时刻上报CSI后的一个建议测量周期内，停止RS的周期性测量。
在一个实施例中，若基于有效时长确定CSI的建议上报周期，当CSI的建议上报周期大于或等于有效时长时，则在基于目标时刻上报CSI后的一个建议上报周期内或一个有效时长内，停止CSI的周期性上报。
在一个实施例中，若基于有效时长确定CSI的建议上报周期，当CSI的建议上报周期小于有效时长时，则可以在基于目标时刻上报CSI后的一个建议上报周期内，停止CSI的周期性上报。
如此，在CSI可持续表征信道状态的有效时长内，停止执行RS的周期性测量和/或CSI的周期性上报，可以充分利用有效时长内CSI的有效性，减少频繁执行周期性测量和周期性上报产生的功耗。
在一些实施例中，方法还可包括：向基站发送CSI预测结果。
这里，终端可以用于对CSI进行预测得到CSI预测结果，并将CSI预测结果发送给基站。其中， 向基站发送的CSI预测结果，可以用于建议基站终端下一次测量RS和/或上报CSI的建议周期。其中，建议的周期值可以是具体的时间单位的个数，也可以是RRC已配置的RS周期性测量和/或CSI周期性上报的配置信息中指示的周期ID或周期索引值(index)等。
在一个实施例中，向基站发送CSI预测结果，可以为在上报CSI时将CSI预测结果一并上报给基站。例如，预测得到CSI预测结果后，在下一次CSI上报时将CSI预测结果携带在CSI上报信令中，上报给基站。
例如，CSI上报对应的CSI上报信令携带的内容，可以包括：当前测量RS得到的CSI以及CSI预测结果。
在一个实施例中，向基站发送CSI预测结果，可以为响应于基站发送的上报CSI预测结果的请求，通过媒体访问控制控制单元(Medium Access Control-Control Element，MAC-CE)对CSI预测结果进行上报。例如，通过MAC-CE发送建议的RS测量周期和/或CSI上报周期。
在一个实施例中，向基站发送CSI预测结果，还可以为终端向基站发送携带CSI预测结果的请求消息(request)等，例如，请求消息用于向基站建议测量周期和/或上报周期。
在一些实施例中，基于CSI预测结果，执行RS的测量和/或CSI的上报，可包括：
若接收到基站响应于CSI预测结果返回的预设指令，则基于CSI预测结果和/或预设指令，执行RS的测量和/或CSI的上报。
在一个实施例中，预设指令可以与向基站发送CSI预测结果的方式相关联。例如，当通过CSI上报信令将CSI预测结果上报给基站时，接收到的预设指令可以为指示终端RS测量行为和/或CSI上报行为的资源配置信息。
示例性的，资源配置信息中可以携带基站基于CSI预测结果确定的RS的测量周期和/或CSI的上报周期，其中，基站指示的测量周期和/或上报周期，可以与终端发送的CSI预测结果中的建议测量周期和/或建议上报周期相同，也可以是基站确定CSI预测结果中的建议测量周期和/或建议上报周期不合理并重新确定的测量周期和/或上报周期。
在一个实施例中，当终端通过MAC-CE上报预测结果时，预设指令可以为基站对于包含此MAC-CE的物理上行共享信道(Physical Uplink Shared Channel，PUSCH)的确认指令(Acknowledge，ACK)。
这里，确认指令可以以隐示的方式下发给终端，例如使用与承载上述PUSCH相同的混合自动重传请求(Hybrid Automatic Repeat request，HARQ)进程号发起新的上行调度。其中，新传数据(New data indicator，NDI)域发生翻转表示新的上行调度。
在一个实施例中，当终端通过请求消息上报CSI预测结果时，预设指令可以为基站基于请求消息返回的确认指令(Acknowledge，ACK)或者否认指令(Non-Acknowledge，NACK)等。其中，ACK可以指示基站确定终端基于该CSI预测结果中的建议测量周期和/或建议上报周期执行测量和/或上报。NACK可以指示基站确定CSI预测结果中的建议测量周期和/或建议上报周期不合理，并指示终端重新确定建议测量周期和/或建议上报周期等。
在一个实施例中，若接收到基站响应于CSI预测结果返回的预设指令，则基于CSI预测结果和/或预设指令，执行RS的测量和/或CSI的上报，可包括：若接收到基站响应于CSI预测结果返回的第一类预设指令，则基于CSI预测结果，执行RS的测量和/或CSI的上报，其中，第一类预设指令指示基站对CSI预测结果中的建议测量周期和/或建议上报周期验证通过，例如ACK。
在一个实施例中，方法还可包括：若接收到基站响应于CSI预测结果返回的第二类预设指令，则重新确定CSI预测结果并将重新确定的CSI预测结果发送给基站，其中，第二类预设指令指示基站对CSI预测结果中的建议测量周期和/或建议上报周期验证失败，例如NACK。
在一个实施例中，若接收到基站响应于CSI预测结果返回的预设指令，则基于CSI预测结果和/或预设指令，执行RS的测量和/或CSI的上报，可包括：若接收到基站响应于CSI预测结果中的有效时长返回的指示非周期性CSI上报的指示信息，则基于指示信息执行RS的测量和/或CSI的上报。
例如基于指示信息指示的非周期性CSI上报时刻，执行RS的测量和/或CSI的上报。
在一个实施例中，当终端通过请求消息上报CSI预测结果时，预设指令还可以为携带在其他信令中的反馈信息，例如携带在基站下发的指示终端测量RS的非周期性测量指示信息，和/或指示终端上报CSI的非周期性上报指示信息等中的ACK或NACK等。如此，通过其他信令携带反馈信息，可以减少基站单独下发ACK或NACK产生的资源开销，从而进一步节省资源占用。
在一些实施例中，向基站发送CSI预测结果，包括：
若在预设时间窗内存在可用的CSI上报资源，则上报CSI与CSI预测结果；
若在预设时间窗内不存在可用的CSI上报资源，则根据基站的指示信息上报CSI与CSI预测结果。
这里，根据基站的指示信息上报CSI与CSI预测结果，可以为根据基站下发的进一步指示信息上报CSI与CSI预测结果。例如，根据基站下发的指示非周期性CSI上报的指示信息，上报CSI与CSI预测结果。
在本公开实施例中，预设时间窗可以为固定值，例如3个slot或5个slot等，或者，预设时间窗也可以根据当前上报CSI的上报周期确定。例如，预设时间窗可以小于或等于当前CSI的上报周期。示例性的，当前CSI的上报周期为6个slot时，预设时间窗可以为当前CSI的1/2即3个slot。
在一个实施例中，若在预设时间窗内不存在可用的CSI上报资源，则根据基站的指示信息上报CSI与CSI预测结果，可以包括：若在预设时间窗内不存在可用的周期性CSI上报的CSI上报资源，且接收到基站下发的指示非周期性CSI上报的指示信息，则基于CSI和CSI预测结果生成请求消息；向基站上报请求消息。
如此，基于预设时间窗内有无待上报CSI的判断，可以减少等待周期性上报CSI对应的上报时刻才能上报预测结果导致效率较低，从而在不同时刻均可以快速高效地上报CSI预测结果，提高终端测量和/或上报控制的效率。
在一些实施例中，基于CSI预测结果，执行RS的测量和/或CSI的上报，包括：
基于接收到预设指令的第一时刻和/或当前时刻之前最后一次上报CSI的第二时刻，确定RS的测量和/或CSI的上报的起始时刻；
基于建议测量周期以及起始时刻执行RS的测量，和/或，基于建议上报周期以及起始时刻执行CSI的上报。
在本公开实施例中，RS的测量的起始时刻，可以为当前时刻之后下一次执行测量的时刻，或者，也可以为基于CSI预测结果中的建议测量周期和/或建议上报周期执行测量的起始时刻。
CSI的上报的起始时刻，可以为当前时刻之后下一次执行上报的时刻，或者，也可以为基于CSI预测结果中的建议上报周期执行上报的起始时刻。
在一个实施例中，基于接收到预设指令的第一时刻和/或当前时刻之前最后一次上报CSI的第二时刻，确定RS的测量和/或CSI的上报的起始时刻，可包括：基于当前时刻之前最后一次上报CSI的第二时刻，以及CSI预测结果指示的建议上报周期，确定CSI的上报的起始时刻。
例如，第二时刻为第m个slot，CSI预测结果指示的新的上报周期为x个slot，则CSI上报的起始时刻为第m+x个slot。
在一个实施例中，基于接收到预设指令的第一时刻和/或当前时刻之前最后一次上报CSI的第二时刻，确定RS的测量和/或CSI的上报的起始时刻，可包括：基于第一时刻和/或第二时刻以及预定时间间隔，确定RS的测量和/或CSI的上报的起始时刻。
示例性的，可以根据接收到预设指令的第一时刻以及预定时间间隔确定RS的测量和/或CSI的上报的起始时刻。例如，第一时刻为第n个slot。预定时间间隔可以根据基站下发的资源配置信息或者根据预定的协议确定，例如预定时间间隔为y个slot，则起始时刻为第n+y个slot。
再示例性的，可以根据当前时刻之前最后一次上报CSI的第二时刻，以及预定时间间隔确定RS的测量和/或CSI的上报的起始时刻。例如，第二时刻为第m个slot，预定时间间隔为y个slot，则起始时刻为第m+y个slot。
在一个实施例中，基于接收到预设指令的第一时刻和/或当前时刻之前最后一次上报CSI的第二时刻，确定RS的测量和/或CSI的上报的起始时刻，可包括：当终端通过请求消息将CSI预测结果上报给基站时，基于接收到基站下发的ACK的第一时刻和/或当前时刻之前最后一次上报CSI的第二时刻，确定RS的测量和/或CSI的上报的起始时刻。
在一个实施例中，基于接收到预设指令的第一时刻和/或当前时刻之前最后一次上报CSI的第二时刻，确定RS的测量和/或CSI的上报的起始时刻，可包括：当终端通过CSI上报信令将CSI预测结果上报给基站时，基于接收到基站下发的CSI资源配置信息的第一时刻和/或当前时刻之前最后一次上报CSI的第二时刻，确定RS的测量和/或CSI的上报的起始时刻。
如此，基于第一时刻和/或第二时刻可以更加准确地确定基于新的测量周期和/或上报周期执行对应的起始时刻，从而可以进一步提高CSI处理过程的控制精准性。
在一些实施例中，方法还可包括：
获取待预测CSI的至少一个待预测时刻；
基于当前RS测量得到的CSI确定待预测时刻对应的CSI预测结果。
在本公开实施例中，待预测时刻为当前时刻之后需要预测CSI的时刻。基于当前RS测量得到的CSI确定待预测时刻对应的CSI预测结果，可以包括：基于当前RS测量得到的CSI以及至少一个历史RS测量得到的历史CSI，确定待预测时刻对应的CSI预测结果。
这里，当前RS测量得到的CSI，可以为当前时刻执行的RS测量得到的CSI，或者，也可以为当前时刻之前最后一次RS测量得到的CSI。
在一个实施例中，基于当前RS测量得到的CSI确定待预测时刻对应的CSI预测结果，可包括：基于当前RS测量得到的CSI，通过确定待预测时刻对应的CSI；基于待预测时刻对应的CSI确定待预测时刻对应的CSI预测结果。
例如，基于待预测时刻对应的CSI确定待预测时刻对应的CSI的有效时长、RS的建议测量周期以及CSI的建议上报周期等。
在一些实施例中，CSI预测结果可通过MAC-CE或者上行控制信息(uplink control information，UCI)上报给基站。
如图6所示，本公开实施例提供一种CSI的处理方法，由终端执行，包括：
S101：接收基站发送的基于CSI预测结果的、对测量周期和/或上报周期的更新指令；
S110：基于CSI预测结果，执行RS的测量和/或CSI的上报。
在本公开实施例中，更新指令可以用于指示终端基于CSI预测结果更新RS测量的测量周期和/或CSI上报的上报周期。其中，更新指令可以仅用于指示触发终端的更新，也可以携带基站进行预测得到的CSI预测结果，例如更新指令携带基站预测得到的测量周期和/或上报周期。
在一个实施例中，更新指令可以为基站基于CSI预测结果发送的，例如携带基站基于CSI预测结果确定的新的测量周期和/或上报周期。或者，更新指令也可以为基站指示终端基于CSI预测结果更新测量周期和/或上报周期的指令。
在一个实施例中，当更新指令仅用于指示触发终端的更新时，方法还可以包括：响应于更新指令对待预测时刻的CSI进行预测，得到CSI预测结果。
在一个实施例中，当更新指令携带基站预测得到的CSI预测结果时，步骤S110可包括：在更新指令携带的CSI预测结果中获取基站指示的RS测量周期和/或CSI上报周期；基于RS测量周期和/或CSI上报周期，执行RS的测量和/或CSI的上报。
在一些实施例中，方法还可包括：
通过用于接收RS和/或上报CSI的时域资源和/或频域资源执行数据传输。
在本公开实施例中，通过用于接收RS和/或上报CSI的时域资源和/或频域资源执行数据传输，可包括：在一个上报周期对应的相邻两个CSI的上报时刻间的时间间隔，通过用于接收RS和/或上 报CSI的时域资源和/或频域资源执行数据传输。
在一个实施例中，通过用于接收RS和/或上报CSI的时域资源和/或频域资源执行数据传输，可包括：在一个上报周期对应的相邻两个CSI的上报时刻间的时间间隔，若未检测到基站下发的指示开始非周期性CSI上报的指示信息，则通过用于接收RS和/或上报CSI的时域资源和/或频域资源执行数据传输。
在一个实施例中，通过用于接收RS和/或上报CSI的时域资源和/或频域资源执行数据传输，还可包括：在一个或多个上报周期对应的相邻两个RS的接收时刻间的时间间隔，通过用于接收RS和/或上报CSI的时域资源和/或频域资源执行数据传输。
如此，在上报周期中停止周期性CSI上报，则可以释放未被占用用于CSI上报或RS下发的时频资源，用于传输终端和基站之间待传输的数据，从而提高资源利用效率，减少额外的资源开销和功耗浪费。
如图7所示，本公开实施例提供一种CSI的处理方法，由基站执行，包括：
S210：获取CSI预测结果；CSI预测结果用于RS的测量和/或CSI的上报。
在本公开实施例中，基站获取CSI预测结果，可以为基站自行预测确定CSI预测结果，或者，也可以为接收终端上报的CSI预测结果。CSI预测结果用于指示终端的RS测量和/或CSI上报，例如CSI预测结果可以指示终端的建议RS测量周期和/或建议CSI上报周期等。
在一个实施例中，CSI预测结果，可以包括：对一个或多个目标时刻或目标时间段预测的CSI，和/或，对一个或多个目标时刻或目标时间段预测的CSI时域预测情况。
其中，目标时刻或目标时间段，可以为基站自行确定或者由终端发送给基站的，例如基站根据当前时刻和/或终端与基站间的预定协议确定的。对一个或多个目标时刻或目标时间段预测的CSI，可以基于当前测量得到的CSI和/或当前时刻之前的预设时间窗内测量得到过的CSI进行预测的。例如，可以基于预设的AI模型进行预测等。
在一个实施例中，方法还可包括：基于CSI预测结果指示的RS的建议测量周期和/或CSI的建议上报周期确定向终端发送RS的发送周期；基于发送周期向终端发送用于RS测量的RS。例如，基站的RS发送周期可以与终端的RS建议测量周期一致，或者与终端的CSI建议上报周期一致等。
在一个实施例中，基站自行预测确定CSI预测结果时，方法还可包括：将CSI预测结果发送给终端。例如，可以包括向终端发送基于CSI预测结果的RS测量周期和/或CSI上报周期的更新指令等。其中，更新指令可以携带CSI预测结果。
在一个实施例中，基站自行预测确定CSI预测结果时，方法还可包括：对CSI预测结果进行验证；若CSI预测结果符合预设条件，则将CSI预测结果发送给终端。例如，当CSI预测结果指示的RS测量周期和/或CSI上报周期符合终端与基站间传输的预设条件时，将CSI预测结果发送给终端。
在一个实施例中，接收终端上报的CSI预测结果时，方法还可包括：对CSI预测结果进行验证；若CSI预测结果符合预设条件，则向终端发送指示基于CSI预测结果执行RS的测量和/或CSI的上 报的预设指令。
如此，基站基于CSI预测结果配置指示终端执行RS的测量和/或CSI的上报的行为，从而可以更加匹配CSI的预测变化情况，从而可以随CSI的预测结果变化灵活调整RS测量及CSI上报的行为，例如调整周期或频率等。因此，可以提高终端执行RS测量和CSI上报的灵活性，减少对测量和上报控制准确性低导致产生较高的资源开销和功耗浪费。
在一些实施例中，CSI预测结果可包括以下至少之一：
在目标时刻接收的CSI的有效时长；

在本公开实施例中，指示信息可以为指示终端上报CSI的指示信息，例如指示终端执行一次非周期性CSI上报的指示信息。其中，指示信息可以为DCI。
在一个实施例中，接收终端响应于指示信息上报的CSI预测结果，可以为在接收终端响应于指示信息上报CSI时一同上报的CSI预测结果。例如，基站接收到终端预测得到CSI预测结果后，在下一次CSI上报的CSI上报信令中携带CSI预测结果。
例如，CSI上报对应的CSI上报信令携带的内容，可以包括：当前测量RS得到的CSI以及CSI预测结果。
在一个实施例中，接收终端响应于指示信息上报的CSI预测结果，还可以为接收终端响应于指示信息上报的携带CSI预测结果的请求消息(request)等，例如，请求消息用于指示基站对CSI预测结果进行验证，以确定CSI预测结果指示的测量周期和/或上报周期是否合理。
在一个实施例中，预设指令可以与基站接收终端发送的CSI预测结果的方式相关联。例如，当通过CSI上报信令接收终端发送的CSI预测结果时，预设指令可以为指示终端RS测量行为和/或CSI上报行为的资源配置信息。
示例性的，资源配置信息中可以携带基站基于CSI预测结果确定的RS的测量周期和/或CSI的上报周期，其中，基站指示的测量周期和/或上报周期，可以与终端发送的CSI预测结果中的建议测量周期和/或建议上报周期相同，也可以是基站确定CSI预测结果中的建议测量周期和/或建议上报周 期不合理并重新确定的测量周期和/或上报周期。
在一个实施例中，当通过请求消息接收终端发送的CSI预测结果时，预设指令可以为基站基于请求消息返回的确认指令(Acknowledge，ACK)或者否认指令(Non-Acknowledge，NACK)等。
其中，ACK可以指示基站确定CSI预测结果中的建议测量周期和/或建议上报周期合理，并指示终端基于该CSI预测结果中的建议测量周期和/或建议上报周期执行测量和/或上报。
NACK可以指示基站确定CSI预测结果中的建议测量周期和/或建议上报周期不合理，并指示终端重新确定建议测量周期和/或建议上报周期等。
在一个实施例中，当通过请求消息接收终端发送的CSI预测结果时，预设指令还可以为携带在其他信令中的反馈信息，例如携带在基站下发的指示终端测量RS的非周期性测量指示信息，和/或指示终端上报CSI的非周期性上报指示信息等中的ACK或NACK等。如此，通过其他信令携带反馈信息，可以减少基站单独下发ACK或NACK产生的资源开销，从而进一步节省资源占用。
在一些实施例中，步骤S210可包括：
获取待预测CSI的至少一个待预测时刻；
基于当前接收到的CSI确定待预测时刻对应的CSI预测结果。
在本公开实施例中，待预测时刻为当前时刻之后需要预测CSI的时刻。基于当前接收到的CSI确定待预测时刻对应的CSI预测结果，可以包括：基于当前接收到的CSI以及至少一个历史接收的历史CSI，确定待预测时刻对应的CSI预测结果。
这里，当前接收到的CSI，可以为当前时刻执行的RS测量得到的CSI，或者，也可以为当前时刻之前最后一次RS测量得到的CSI。
在一个实施例中，基于当前接收到的CSI确定待预测时刻对应的CSI预测结果，可包括：基于当前接收到的CSI，通过确定待预测时刻对应的CSI；基于待预测时刻对应的CSI确定待预测时刻对应的CSI预测结果。
例如，基于待预测时刻对应的CSI确定待预测时刻对应的CSI的有效时长、RS测量周期以及CSI上报周期等。
在一些实施例中，CSI预测结果可通过MAC-CE或者上行控制信息(uplink control information，UCI)接收。
在一些实施例中，方法还包括：
向终端发送基于CSI预测结果的、对测量周期和/或上报周期的更新指令。
在本公开实施例中，更新指令可以用于指示终端基于CSI预测结果更新RS测量的测量周期和/或CSI上报的上报周期。其中，更新指令可以仅用于指示触发终端确定新的测量周期和/或上报周期，也可以携带基站进行预测得到的CSI预测结果，例如更新指令携带基站预测得到的测量周期和/或上报周期。
在一些实施例中，方法还可包括：
基于建议测量周期确定RS的发送周期，并基于发送周期向终端发送RS；
和/或，
接收终端基于建议上报周期上报的CSI。
在本公开实施例中，RS的发送周期可以与终端RS的建议测量周期相同，或者也可以基于RS测量规则和RS的建议测量周期确定发送周期。例如，若每一个发送的RS用于供终端执行一次测量，则RS的发送周期可以与建议测量周期相等。若每一个发送的RS用于供终端执行两次测量，则RS的发送周期可以等于建议测量周期的两倍。
在一些实施例中，方法还可包括：
通过用于发送RS和/或接收CSI的时域资源和/或频域资源执行数据传输。
在本公开实施例中，通过用于发送RS和/或接收CSI的时域资源和/或频域资源执行数据传输，可包括：在一个CSI建议上报周期对应的相邻两个CSI的接收时刻间的时间间隔，通过用于发送RS和/或接收CSI的时域资源和/或频域资源执行数据传输。
在一个实施例中，通过用于发送RS和/或接收CSI的时域资源和/或频域资源执行数据传输，可包括：在一个CSI的建议上报周期对应的相邻两个CSI的接收时刻间的时间间隔，若未下发的指示开始非周期性CSI上报的指示信息，则通过用于发送RS和/或接收CSI的时域资源和/或频域资源执行数据传输。
在一个实施例中，通过用于发送RS和/或接收CSI的时域资源和/或频域资源执行数据传输，还可包括：在一个或多个CSI的建议上报周期对应的相邻两个RS的发送时刻间的时间间隔，通过用于发送RS和/或接收CSI的时域资源和/或频域资源执行数据传输。
例如，每一个RS用于供终端执行多次测量时，相邻两个RS的发送时刻之间会包含多个CSI的上报周期。
如此，在上报周期中停止周期性CSI上报，则可以释放未被占用用于CSI上报或RS下发的时频资源，用于传输终端和基站之间待传输的数据，从而提高资源利用效率，减少额外的资源开销和功耗浪费。
本公开实施例提供一种CSI的处理方法，包括：
1、UE向基站上报新的CSI上报内容(可以包括以下至少之一)：
1)一组CSI值
基于基站的配置，UE上报包括当前测量的CSI结果，以及UE预测的未来一段时间的CSI预测结果。
每个CSI对应的待预测时刻可以由基站提前配置或者UE决定。
2)CSI有效时长
本次CSI上报内容的有效时间，例如1s、2s或5s等。
在有效时长内UE不再进行周期或者半静态CSI上报以及测量：基站可以在已配置的RS下发资源和/或CSI上报资源调度其他用户的数据传输，或者调度该用户的数据传输。
如果有效时长内基站触发了非周期上报，则UE依然要进行非周期上报。
3)建议的CSI上报周期和/或RS测量周期，也可以上报预测的CSI变化率。
2、具体的，方法可包括：
1)基于UE触发，测量周期和/或上报周期的周期值由UE建议，基站决定是否采纳。
2)若基站采纳，则UE以新的测量周期和/或上报周期进行RS接收和/或CSI上报。RS接收和/或CSI上报的起始时刻的确定由以下方法之一确定：
收到Ack的第x个slot之后，即假设在slot n收到ack，则UE在slot n+x接收CSI-RS和/或发送CSI；
如图9所示，UE请求消息(request)为UE向基站发送的请求消息，基站反馈信息(gNodeB Acknowledge，gNB ACK)为基站(gNodeB，gNB)基于请求消息返回的ACK。距离上一次RS接收和/或CSI上报的x个slot后，假设UE发送请求消息之前周期是y(每隔y个slot发送一次CSI)，UE建议的周期是x，UE上一次发送CSI的slot是n，那么UE在第n+x个slot作为起始时刻开始发送CSI。前述方法同样适用于RS接收起始时刻的确定。
