背景技术
众所周知，在新空口(New Radio，NR)系统中，引入了非周期信道状态信息(Channel State Information，CSI)上报机制。传统的CSI上报的触发由网络设备通过下行控制信息(Downlink Control Information，DCI)触发，也就是说，网络设备通过下行信令进行上行调度，以触发非周期CSI上报。在下行业务量较多时，或没有上行业务时，触发CSI上报需要上行调度的下行信令，造成额外的信令开销，导致下行信令的开销较大。
发明内容
本发明实施例提供一种信道状态信息CSI上报方法、终端及计算机可读存储介质，以解决非周期CSI上报导致下行信令的开销较大的问题。
第一方面，本发明实施例提供一种信道状态信息CSI上报方法，应用于终端，包括：
接收网络设备发送的物理下行共享信道PDSCH；
在N个PDSCH对应的混合自动重传请求应答HARQ-ACK信息包括至少一个目标HARQ-ACK的情况下，上报CSI；
其中，N为正整数，所述目标HARQ-ACK为确认应答或非确认应答。
第二方面，本发明实施例还提供一种终端，包括：
接收模块，用于接收网络设备发送的物理下行共享信道PDSCH；
上报模块，用于在N个PDSCH对应的混合自动重传请求应答HARQ-ACK信息包括至少一个目标HARQ-ACK的情况下，上报CSI；
其中，N为正整数，所述目标HARQ-ACK为确认应答或非确认应答。
第三方面，本发明实施例还提供一种终端，包括：存储器、处理器及存储在所述存储器上并可在所述处理器上运行的程序，所述程序被所述处理器执行时实现上述信道状态信息CSI上报方法的步骤。
第四方面，本发明实施例还提供一种计算机可读存储介质，所述计算机可读存储介质上存储有计算机程序，所述计算机程序被处理器执行时实现上述信道状态信息CSI上报方法的步骤。
第五方面，本发明实施例还提供一种终端，所述终端被配置成用于执行上述信道状态信息CSI上报方法。
第六方面，本发明实施例还提供一种计算机程序产品，所述计算机程序产品被存储在非易失的存储介质中，所述程序产品被配置成被至少一个处理器执行以实现上述信道状态信息CSI上报方法的步骤。
本发明实施例通过接收网络设备发送的物理下行共享信道PDSCH；在N个PDSCH对应的混合自动重传请求应答HARQ-ACK信息包括至少一个目标HARQ-ACK的情况下，上报CSI。这样，直接基于HARQ-ACK信息触发CSI上报，从而降低了下行信令的开销。

本申请的说明书和权利要求书中的术语“包括”以及它的任何变形，意图在于覆盖不排他的包含，例如，包含了一系列步骤或单元的过程、方法、系统、产品或设备不必限于清楚地列出的那些步骤或单元，而是可包括没有清楚地列出的或对于这些过程、方法、产品或设备固有的其它步骤或单元。此外，说明书以及权利要求中使用“和/或”表示所连接对象的至少其中之一，例如A和/或B，表示包含单独A，单独B，以及A和B都存在三种情况。
在本发明实施例中，“例如”等词用于表示作例子、例证或说明。本发明实施例中被描述为“示例性的”或者“例如”的任何实施例或设计方案不应被解释为比其它实施例或设计方案更优选或更具优势。确切而言，使用“示例性的”或者“例如”等词旨在以具体方式呈现相关概念。
下面结合附图介绍本发明的实施例。本发明实施例提供的一种信道状态信息CSI上报方法、终端及计算机可读存储介质可以应用于无线通信系统中。该无线通信系统可以为第五代(5 th Generation，5G)系统，或者演进型长期演进(Evolved Long Term Evolution，eLTE)系统，或者后续演进通信系统。
请参见图1，图1是本发明实施例可应用的一种网络系统的结构图，如图1所示，包括终端11和网络设备12，其中，终端11可以是用户终端或者其他终端侧设备，例如：手机、平板电脑(Tablet Computer)、膝上型电脑(Laptop Computer)、个人数字助理(personal digital assistant，PDA)、移动上网装置(Mobile Internet Device，MID)或可穿戴式设备(Wearable Device)等终端 侧设备，需要说明的是，在本发明实施例中并不限定终端11的具体类型。上述网络设备12可以是5G基站，或者以后版本的基站，或者其他通信系统中的基站，或者称之为节点B，演进节点B，或者发送接收点(Transmission Reception Point，TRP)，或者接入点(Access Point，AP)，或者所述领域中其他词汇，只要达到相同的技术效果，所述网络设备不限于特定技术词汇。另外，上述网络设备12可以是主节点(Master Node，MN)，或者辅节点(Secondary Node，SN)。需要说明的是，在本发明实施例中仅以5G基站为例，但是并不限定网络设备的具体类型。
为了方便理解，以下结合对本发明实施例涉及的一些内容进行说明：
NR中的业务场景。
在NR技术标准化过程中，主要考虑了三大类使用场景：增强型移动宽带(enhanced Mobile BroadBand，eMBB)、海量机器类通信(massive Machine Type Communications，mMTC)和超高可靠超低时延通信(Ultra-Reliable and Low Latency Communications，URLLC)。三类使用场景在数据速率、时延、可靠性、连接数、业务量密度、移动性等方面的性能要求都存在较大的差异。eMBB场景重点关注数据速率和业务量密度，mMTC场景重点关注连接数，URLLC场景重点关注时延和可靠性。因为这些类别的场景与业务属性和承载要求密切相关，后续称它们为业务场景。目前的标准化研究重点关注eMBB和URLLC这两种业务场景。
NR中非周期CSI的触发与上报。
类似于LTE，在NR中也引入了下行非周期CSI上报机制，即基站可以根据需要使用上行调度触发下行CSI在调度的物理上行共享信道(Physical Uplink Shared Channel，PUSCH)上传输。基站可以通过无线资源控制(Radio Resource Control，RRC)信令预先为终端(User Equipment，UE)配置一个非周期触发状态列表(Aperiodic Trigger State List)，每个状态对应于一个关联的上报配置信息列表，每项上报配置信息指明如何上报以及使用哪些信道状态信息参考信号(Channel State Information Reference Signal，CSI-RS)资源集合。在上行调度DCI(目前仅DCI Format 0_1支持非周期CSI触发)中通过“CSI request”域来具体指示哪一个预先配置的非周期触发状态实际被触发，并且对 应的CSI上报信息在调度的PUSCH上承载。
调度的PUSCH所在时隙与上行调度DCI所在时隙之间的偏移量K2(单位为时隙)确定如下：
当PUSCH承载传输块(Transport Block,TB)，且不携带或携带下行非周期CSI上报信息时，由“Time domain resource assignment”域作为索引来确定预先配置或指定的表格中生效的行，取生效行中的时隙偏移作为应用的K2值。
当PUSCH不承载TB，只承载下行非周期CSI上报信息时，先由“Time domain resource assignment”域作为索引来确定实际触发的非周期触发状态对应的上报配置信息列表中各项上报配置信息的上报时隙偏移列表中生效的上报时隙偏移，再取这一个或多个上报时隙偏移(上报时隙偏移数目＝列表中上报配置信息项数)中最大的取值，作为应用的K2值。
考虑到CSI的计算开销较大，在NR协议中规定了承载CSI report的PUSCH的第一个上行符号(symbol)的时间位置要求，不早于如下任意符号位置：
Zref，其定义为相对于触发DCI的结束时刻，T proc,CSI＝(Z)(2048+144)·κ2 -μ·T C之后的第一个上行符号；
Z'ref(n)，其定义为相对于使用的非周期测量资源中最晚资源占用的最后一个符号的结束时刻，T' proc,CSI＝(Z')(2048+144)·κ2 -μ·T C之后的第一个上行符号
上述Z和Z'在不同情况下可参考下表一或表二中的对应取值。
表一：
Figure PCTCN2021071722-appb-000001
表二：
Figure PCTCN2021071722-appb-000002
当调度的PUSCH不满足上述时间位置要求时，UE可以忽略对应的非周期CSI上报(当未与HARQ-ACK或TB复用时)，或者不更新对应的CSI信息。
混合自动重传请求应答码本(Hybrid Automatic Repeat reQuest-Acknowledgement codebook，HARQ-ACK codebook)：
对于支持TB-level反馈的HARQ-ACK过程，每一个TB对应于反馈一个HARQ-ACK bit，支持每个UE的多个下行(Downlink，DL)HARQ进程，也支持每个UE的单个DL HARQ进程，UE需要指示其最小HARQ处理时间的能力(最小HARQ处理时间意味着从DL数据接收到相应的HARQ-ACK传输定时所需的最小时间)。对于eMBB和URLLC支持异步和自适应DL HARQ。从UE的角度来看，多个物理下行共享信道(Physical downlink shared channel，PDSCH)的HARQ-ACK反馈在时间上可以在一个上行(Uplink，UL)数据或控制区域中传输，在这个UL上构成一个HARQ-ACK codebook。在DCI中指定了PDSCH接收与对应的ACK/NACK之间的定时(参见DCI 1_0、DCI 1_1中的PDCSCH-to-HARQ定时指示符)。
目前支持两种类型的HARQ-ACK codebook，类型1(type-1)：半静态(semi-static)HARQ-ACK codebook和类型2(type-2)：动态(dynamic)HARQ-ACK codebook。对于semi-static HARQ-ACK codebook，UE根据RRC配置的PDCCH的检测机会(PDCCH monitoring occasion)，PDSCH的时域资源分配(PDSCH-TimeDomainResourceAllocation)、PDSCH到HARQ-ACK的反馈定时(dl-DataToUL-ACK或PDSCH-toHARQ-timing)等参数确定某个时隙可能反馈的所有PDSCH确定HARQ-ACK codebook，由于可能包含对实际调度的和为调度的PDSCH的HARQ，其码本一般会较大。对于dynamic HARQ-ACK codebook，UE根据实际调度的PDSCH确定HARQ-ACK codebook，由于只对实际调度的PDSCH进行反馈，因此其HARQ-ACK的码本大小通常会小于semi-static HARQ-ACK codebook的码本大小。UE具体使用哪个类型的码本，是通过RRC配置确定的。
请参见图2，图2是本发明实施例提供的一种CSI上报方法的流程图，该方法应用于终端，如图2所示，包括以下步骤：
步骤201，接收网络设备发送的物理下行共享信道PDSCH；
步骤202，在N个PDSCH对应的混合自动重传请求应答HARQ-ACK信息包括至少一个目标HARQ-ACK的情况下，上报CSI；
其中，N为正整数，所述目标HARQ-ACK为确认应答(ACK)或非确认应答(Negative Acknowledgement，NACK)。
本发明实施例中，上述N个PDSCH可以为一个或者多个时间单元内接收到的PDSCH，基于每一PDSCH的解码情况确定每一PDSCH对应的HARQ-ACK。例如若PDSCH解码正确，则该PDSCH对应的HARQ-ACK为ACK；若PDSCH解码错误，则该PDSCH对应的HARQ-ACK为NACK。换句话说，本发明实施例中，根据N个PDSCH的解码情况，确定是否上报CSI。
可选的，对于一次CSI上报的判断，可以理解为：每接收到N个PDSCH时，进行一次CSI上报判断；也可以理解为：存在PDSCH时，基于预设时间段内接收到的N个PDSCH对应的HARQ-ACK，进行一次CSI上报判断。换句话说，在时间单元A反馈N个PDSCH对应的HARQ-ACK信息时，进行一次CSI上报的判断。应理解，时间单元A可以理解为该N个PDSCH对应的HARQ-ACK信息的时间，由网络设备通过高层信令指示或通过调度信令指示。
其中，一实施例中，时间单元A可以理解为判断是否上报CSI的一个时间单元，N个PDSCH对应的G个HARQ-ACK在该时间单元A进行反馈，其中G为≥N的正整数，可选的，当一个PDSCH包含2个TB时，对应的HARQ-ACK数最多为2。当终端配置了基于码块组(Code block group，CBG)的HARQ-ACK反馈时，一个PDSCH包含C个CBG，对应的HARQ-ACK数为C。
在另一实施例中，时间单元A可以理解为判断是否上报CSI的时间集合，即时间单元A包括至少两个时间单元，例如时间单元A1到时间单元(A1+K)，其中，K为正整数。
本发明实施例通过接收网络设备发送的物理下行共享信道PDSCH；在N个PDSCH对应的混合自动重传请求应答HARQ-ACK信息包括至少一个目标HARQ-ACK的情况下，上报CSI。这样，直接基于HARQ-ACK信息触发 CSI上报，从而降低了下行信令的开销。
进一步的，为了提高CSI上报的针对性，还可以进一步对目标HARQ-ACK进行限定。例如，可选的，在一实施例中，上述至少一个目标HARQ-ACK满足以下至少一项：
条件1，在所述目标HARQ-ACK为非确认应答的情况下，所述目标HARQ-ACK的数量大于或等于第一预设值；
条件2，在所述目标HARQ-ACK为确认应答的情况下，所述目标HARQ-ACK的数量小于或等于第二预设值；
条件3，在所述目标HARQ-ACK为非确认应答的情况下，所述目标HARQ-ACK的比例大于或等于第三预设值；
条件4，在所述目标HARQ-ACK为确认应答的情况下，所述目标HARQ-ACK的比例小于或等于第四预设值；
条件5，所述至少一个目标HARQ-ACK对应至少一个HARQ-ACK码本；
条件6，所述至少一个目标HARQ-ACK对应至少一个半持续调度(Semi-Persistent Scheduling，SPS)PDSCH；
条件7，所述至少一个目标HARQ-ACK对应至少一个SPS释放信令。
本发明实施例中，可以由网络设备控制终端采用ACK和/或NACK触发CSI上报，例如，可以通过DCI指示或者通过RRC配置具体基于ACK和/或NACK触发CSI上报。
在一实施例中，通过DCI指示第一指示信息和/或者通过RRC配置第一配置信息的情况下，基于NACK确定是否上报CSI，其中，该第一指示信息用于指示基于NACK上报CSI，该第一配置信息用于指示基于NACK上报CSI。
在另一实施例中通过DCI指示第二指示信息和/或者通过RRC配置第二配置信息的情况下，基于ACK确定是否上报CSI，其中，该第二指示信息用于指示基于ACK上报CSI，该第二配置信息用于指示基于ACK上报CSI。
在又一实施例中，通过DCI指示第三指示信息和/或通过RRC配置第三配置信息的情况下，基于ACK和NACK确定是否上报CSI。其中，该第三指示信息用于指示基于ACK和NACK上报CSI，该第三配置信息用于指示基 于ACK和NACK上报CSI。
在又一实施例中，通过DCI指示第四指示信息或者通过RRC配置第四配置信息的情况下，基于ACK或NACK确定是否上报CSI。其中，该第四指示信息用于指示基于ACK或NACK上报CSI，该第四配置信息用于指示基于ACK或NACK上报CSI。
当然在其他实施例中，DCI指示的指示信息和/或RRC配置的配置信息还可以指示UE不基于HARQ-ACK上报CSI。换句话说，网络设备通过DCI指示第五指示信息或者通过RRC配置第五配置信息的情况下，终端不上报CSI。其中，该第五指示信息用于指示不上报CSI，第五配置信息用于指示不上报CSI。
可选的，上述DCI的格式可以为回退(fallback)DCI格式或非回退(non-fallback)DCI格式，具体的，fallback DCI格式可以为DCI格式1_0，non-fallback DCI格式可以为DCI格式1_1或DCI格式1_2。
在本发明实施例中，上述第一预设值、第二预设值、第三预设值和第四预设值的大小可以根据实际需要进行设置，在此不做进一步的限定。其中，第一预设值可以大于第二预设值，第三预设值可以大于第四预设值。可选的，在一实施例中，该第一预设值、所述第二预设值、所述第三预设值和所述第四预设值由协议规定或网络配置。例如，在一实施例中，上述第一预设值可以为G。
本发明实施例中，可以根据实际情况，设置满足条件1至条件7中的一项或者多项时，则上报CSI。
针对上述条件1和条件2，可以理解为，部分或者全部目标HARQ-ACK的数量。针对上述条件3和条件4可以理解为，部分或者全部HARQ-ACK对应的比例。
针对上述条件5，HARQ-ACK信息可以对应一个或者多个HARQ-ACK码本，换句话说，HARQ-ACK信息包括的多个HARQ-ACK归属于一个或者多个HARQ-ACK码本。上述至少一个目标HARQ-ACK对应至少一个HARQ-ACK码本可以理解为HARQ-ACK信息对应至少两个HARQ-ACK码本时，至少一个HARQ-ACK码本包括至少一个所述目标HARQ-ACK。
在一实施例中，进一步的，上报CSI的条件还可以包括：HARQ-ACK信息对应P个HARQ-ACK码本的情况下，其中Q1个HARQ-ACK码本包含至少一个目标HARQ-ACK，该Q1个HARQ-ACK码本的优先级大于剩余的P-Q1个HARQ-ACK码本的优先级，Q1为小于P的正整数，P为大于1的整数。
在另一实施例中，进一步上报CSI的条件还可以包括：P个HARQ-ACK码本的情况下，其中Q2个HARQ-ACK码本包含至少一个目标HARQ-ACK。Q2为小于P的正整数，Q2为网络配置。
进一步的，在一实施例中，还可以定义高优先级的HARQ-ACK码本包括目标HARQ-ACK时，则上报CSI。例如，所述至少一个HARQ-ACK码本包括P个HARQ-ACK码本的情况下，所述P个HARQ-ACK码本中第一HARQ-ACK码本的优先级大于第二HARQ-ACK码本的优先级，所述第二HARQ-ACK码本为所述P个HARQ-ACK码本中除所述第一HARQ-ACK码本之外的其他HARQ-ACK码本，P为大于1的整数。
针对上述条件6，在N个PDSCH中，包含一个或者多个SPS PDSCH，可选的，至少一个半持续调度SPS PDSCH对应的HARQ-ACK为所述目标HARQ-ACK时，上报CSI；换句话说，部分或者全部的SPS PDSCH对应的HARQ-ACK为所述目标HARQ-ACK，例如目标HARQ-ACK为NACK时，至少一个SPS PDSCH反馈NACK，则上报CSI。
进一步的，在一实施例中，可以定义高优先级的SPS PDSCH对应HARQ-ACK为所述目标HARQ-ACK，上报CSI。例如，所述至少一个SPS PDSCH包括第一SPS PDSCH，所述第一SPS PDSCH的优先级大于第二SPS PDSCH的优先级。其中，所述第二SPS PDSCH为所述终端配置的SPS PDSCH中除所述第一SPS PDSCH之外的SPS PDSCH，第一SPS PDSCH对应HARQ-ACK为所述目标HARQ-ACK。
可选的，上述至少一个SPS PDSCH可以对应至少一个SPS资源配置。至少一个SPS PDSCH的数量大于1时，可以包括第一SPS PDSCH和第三SPS PDSCH，所述第一SPS PDSCH的优先级大于第三SPS PDSCH的优先级，所述第三SPS PDSCH为所述至少一个SPS PDSCH中除所述第一SPS  PDSCH之外的SPS PDSCH。其次，所述至少一个SPS PDSCH对应的SPS资源配置包含第一SPS资源配置，所述第一SPS资源配置所配置的SPS PDSCH的优先级大于第二SPS资源配置所配置的SPS PDSCH的优先级，所述第二SPS资源配置为至少一个SPS PDSCH对应的SPS资源配置中除所述第一SPS资源配置之外的SPS资源配置。
应理解，本实施例中，高优先级的SPS PDSCH可以理解为SPS PDSCH对应的HARQ-ACK归属的HARQ-ACK码本为高优先级，也就是说SPS PDSCH对应的高优先级的目标HARQ-ACK。
针对上述条件7，可以理解为至少一个SPS释放(release)信令对应的HARQ-ACK为所述目标HARQ-ACK；换句话说，部分或者全部的SPS release信令对应的HARQ-ACK为所述目标HARQ-ACK，例如目标HARQ-ACK为NACK时，至少一个SPS release信令反馈NACK，则上报CSI报告。
本实施例中，网络设备在一段时间内可以发送一个或者多个SPS release信令，在终端接收到SPS release信令时，确定SPS release信令对应反馈的HARQ-ACK，当SPS release信令对应反馈的HARQ-ACK包括至少一个目标HARQ-ACK的情况下，可以触发上报CSI。也就是说，在本实施例中，可以包括以下步骤：
终端接收网络设备发送的SPS release信令；
在T个SPS release信令中至少一个SPS release信令对应的HARQ-ACK为目标HARQ-ACK的情况下，上报CSI；其中，T为正整数。进一步的，还可以限定在T个SPS release信令中存在Y个SPS release信令对应的HARQ-ACK为目标HARQ-ACK的情况下，上报CSI。Y的取值可以由网络设备配置或协议约定，例如Y可以为小于或等于T的正整数。
进一步的，每一SPS release信令对应的HARQ-ACK可以与N个PDSCH对应的混合自动重传请求应答HARQ-ACK信息一起传输。
需要说明的是，上述HARQ-ACK信息可以在M个时间单元传输，该M为正整数，也就是说，HARQ-ACK信息对应的HARQ-ACK在一个或者多个时间单元传输。应理解，在一实施例中，HARQ-ACK信息对应的HARQ-ACK码本的数量为M，即在每一个时间单元传输一个HARQ-ACK码本。在另一 实施例中，HARQ-ACK码本的数量为U，U≥M，其中，M个时间单元中的每个时间单元传输至少一个HARQ-ACK码本。换句话说，在本发明实施例中，所述HARQ-ACK信息的传输是在时间单元m上进行的；或者，所述HARQ-ACK信息的传输是在时间单元m～时间单元n上进行的，n>m。
可选的，上述时间单元可以理解为时隙(slot)、子时隙(sub-slot)、symbol或子帧(subframe)等，在此不做进一步的限定。
进一步的，在M大于1时，所述至少一个目标HARQ-ACK满足以下至少一项：
在所述目标HARQ-ACK为非确认应答的情况下，在L个时间单元内，所述目标HARQ-ACK的数量大于或等于第五预设值；
在所述目标HARQ-ACK为确认应答的情况下，在L个时间单元内，所述目标HARQ-ACK的数量小于或等于第六预设值；
在所述目标HARQ-ACK为非确认应答的情况下，在L个时间单元内，所述目标HARQ-ACK的比例大于或等于第七预设值；
在所述目标HARQ-ACK为确认应答的情况下，在L个时间单元内，所述目标HARQ-ACK的比例小于或等于第八预设值；
其中，L为小于或等于M的正整数。
在本发明实施例中，上述第五预设值、第六预设值、第七预设值和第八预设值的大小可以根据实际需要进行设置，在此不做进一步的限定。其中，第五预设值可以大于第六预设值，第七预设值可以大于第八预设值。可选的，在一实施例中，该第五预设值、第六预设值、第七预设值和第八预设值由协议规定或网络配置。例如，在一实施例中，上述第五预设值可以小于或等于1。
上述L的大小可以根据实际需要进行设置，例如在本发明实施例中，L的值可以由网络设备配置或者协议约定。
可选的，在一实施例中，L小于M时，所述L个时间单元为所述M个时间单元中，按照时间从先到后排列的最后L个时间单元。例如，HARQ-ACK信息在四个时间单元(时间单元1、时间单元2、时间单元3和时间单元4)上传输时，若L为2，则可以根据时间单元3和时间单元4内反馈的HARQ- ACK信息确定是否上报CSI。
可选的，在一实施例中，在所述L个时间单元内，每一时间单元包括至少一个所述目标HARQ-ACK。例如，HARQ-ACK信息在四个时间单元(时间单元1、时间单元2、时间单元3和时间单元4)上传输时，在时间单元1、时间单元2、时间单元3和时间单元4内的每一时间单元反馈的HARQ-ACK均包括目标HARQ-ACK时，将会触发上报CSI。由于限定在每一时间单元反馈的HARQ-ACK均包括目标HARQ-ACK，从而可以确定用户的信道状态较差，从而触发上报CSI，从而可以减少CSI上报的次数，提高CSI上报的有效性。
可选的，在一实施例中，上述目标HARQ-ACK的数量包括以下任一项：
一个HARQ-ACK码本中目标HARQ-ACK的数量，所述HARQ-ACK码本为所述HARQ-ACK信息对应的任一个HARQ-ACK码本；
所述HARQ-ACK信息对应的所有HARQ-ACK码本中目标HARQ-ACK的数量；
第一服务小区(serving cell)的目标HARQ-ACK的数量，所述第一服务小区为所述HARQ-ACK码本对应的所有服务小区中的任一服务小区；
所述HARQ-ACK码本对应的所有服务小区的目标HARQ-ACK的数量之和。
上述目标HARQ-ACK的比例包括以下任一项：
一个HARQ-ACK码本中目标HARQ-ACK的数量与所述HARQ-ACK码本包含的HARQ-ACK的数量的比值，所述HARQ-ACK码本为所述HARQ-ACK信息对应的任一个HARQ-ACK码本；
所述HARQ-ACK信息对应的所有HARQ-ACK码本中目标HARQ-ACK的数量与所有HARQ-ACK码本包含的HARQ-ACK的数量的比值；
第二服务小区的目标HARQ-ACK的数量与所述第二服务小区的HARQ-ACK的数量，所述第二服务小区为所述HARQ-ACK码本对应的所有服务小区中的任一服务小区；
所述HARQ-ACK码本对应的所有服务小区的目标HARQ-ACK的数量之和与所有服务小区的HARQ-ACK的数量之和的比值。
应理解，上述CSI的上报可以在物理上行控制信道(Physical Uplink Control Channel，PUCCH)上传输。在一实施例中，可以与HARQ-ACK复用一起发送CSI报告。本发明实施例中，上报的CSI应理解为非周期CSI报告。
可选的，基于NACK触发的CSI报告可以为类型A(即CSI报告A)，基于ACK触发的CSI报告为类型B(即CSI报告B)。其中，CSI报告A包含的目标对象与CSI报告B包含的目标对象相同或者不同，该目标对象可以为内容或比特数。
可选的，在一实施例中，CSI报告A可以包含整个带宽(wideband)信道质量指示(Channel Quality Indicator，CQI)和/或wideband预编码矩阵指示(Precoding matrix indicator，PMI)等；CSI报告B包含子带(subband)CQI和/或subband PMI等；在另一实施例中，CSI报告A包含subband CQI和/或subband PMI等；CSI报告B包含wideband CQI和/或wideband PMI等。

条件五，时间n～时间n+k中至少包含一个SPS PDSCH对应的NACK信息；进一步的，至少包含一个SPS PDSCH对应的NACK信息可以理解为至少包含一个高优先级的SPS PDSCH的NACK信息。
针对上述场景1和场景2还可以进行以下扩展。
可选的，在一实施例中，上述NACK可以替换为ACK。
可选的，网络设备指示UE基于ACK和/或NACK触发CSI上报。
例如，一实施例中，DCI指示了第一指示信息和/或RRC配置了第一配置信息时，UE在需要反馈NACK时，上报CSI。DCI指示了第二指示信息或RRC配置了第二配置信息时，UE在需要反馈ACK时，上报CSI。DCI指示了第三指示信息或RRC配置了第三配置信息时，UE在需要反馈ACK或NACK时，上报CSI。
可选的，对于NACK的数量或比例的统计方法可以包括以下任一项：
方式1，NACK的比例等于一个HARQ-ACK码本中NACK的数量除以该HARQ-ACK码本中HARQ-ACK的数量；
方式2，NACK的比例等于所有HARQ-ACK码本中的NACK的数量除以所有HARQ-ACK码本中的HARQ-ACK的数量；
方式3，NACK的比例等于一个HARQ-ACK码本中一个serving cell的NACK的数量除以该HARQ-ACK码本中该serving cell的HARQ-ACK的数量；
方式4，一个HARQ-ACK码本对应的所有服务小区的目标HARQ-ACK的数量之和除以所有服务小区的HARQ-ACK的数量之和。
应理解，上述HARQ-ACK码本可以理解为Type 1 HARQ-ACK码本或Type 2 HARQ-ACK码本。
可选的，关于CSI上报，可以满足以下至少一项：
在PUCCH上报CSI；
与HARQ-ACK复用一起发送CSI报告；
上报的CSI为非周期CSI报告；
基于NACK触发的CSI报告可以为类型A(即CSI报告A)，基于ACK触发的CSI报告为类型B(即CSI报告B)。其中，CSI报告A包含的目标对象与CSI报告B包含的目标对象相同或者不同，该目标对象可以为内容或比特数。应理解，本发明实施例中，上报CSI可以理解为反馈或者发送CSI报告。
如图3所示，在一实施例中，当UE接收到PDSCH 1～4，并且在slot n反馈HARQ-ACK码本1，该HARQ-ACK码本1包含PDSCH 1～4对应的HARQ-ACK信息，当PDSCH 1～4的HARQ-ACK均为ACK时，UE不上报CSI。
如图4所示，在一实施例中，当UE接收到PDSCH 1～4，并且在slot n反馈HARQ-ACK码本1，该HARQ-ACK码本1包含PDSCH 1～4对应的HARQ-ACK信息，当PDSCH 1和PDSCH4的HARQ-ACK为NACK时，即HARQ-ACK码本1包含至少一个NACK信息，UE上报CSI。
如图5所示，在一实施例中，UE接收到PDSCH 1～4，并且在slot n反馈PDSCH 1～4对应的HARQ-ACK信息，其中每个PDSCH对应的HARQ-ACK是在一个sub-slot上反馈。
当在sub-slot 2～4中，UE反馈连续N＝3个NACK信息(N为网络配置 值)，即PDSCH 2～4对应的HARQ-ACK信息为NACK，UE上报CSI。
如图6所示，在一实施例中，UE接收到PDSCH 1～4，并且在slot n反馈PDSCH 1～4对应的HARQ-ACK信息，其中PDSCH 1～2对应的HARQ-ACK码本1的优先级为高，HARQ-ACK码本1是在sub-slot 1上传输；PDSCH 3～4对应的HARQ-ACK码本2的优先级为低，HARQ-ACK码本2是在sub-slot 2上传输。
虽然低优先级的HARQ-ACK码本2包含PDSCH 3和PDSCH 4对应的NACK信息，但由于高优先级的HARQ-ACK码本1，未包含NACK信息，因此UE不上报CSI。
如图7所示，在一实施例中，UE接收到PDSCH 1～4，并且在slot n反馈PDSCH 1～4对应的HARQ-ACK信息，其中PDSCH 1～2对应的HARQ-ACK码本1的优先级为高，HARQ-ACK码本1是在sub-slot 1上传输；PDSCH 3～4对应的HARQ-ACK码本2的优先级为低，HARQ-ACK码本2是在sub-slot 2上传输。
