Description

信息报告方法、装置、设备及存储介质 技术领域
本申请实施例涉及通信技术领域，特别涉及一种信息报告方法、装置、设备及存储介质。
背景技术
CSI(Channel State Information，信道状态信息)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。
目前，在NR(New Radio，新空口)系统的相关技术中，CSI是基于终端设备对CSI-RS(CSI Reference Signals，CSI参考信号)资源的测量获取并上报至网络设备的，具体而言，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。在一些实现中，为了同时满足URLLC(Ultra-Reliable and Low Latency Communication，低时延高可靠通信)业务的低时延与高可靠这两个特性，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。
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，提出了一种新型的信道状态信息。而关于如何得到该新型的信道状态信息，还需要进一步地讨论和研究。

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一些名词和相关技术等进行简单地介绍。
1、信道状态信息(CSI)。
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。
目前，在NR系统的相关技术中，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，具体而言，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 PCTCN2021109656-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。
2、MCS(Modulation and Coding Scheme，调制与编码策略)table(表格)。
NR系统的上行和下行均支持3个MCS表格，分别为256QAM(Quadrature Amplitude Modulation，正交振幅调制)、64QAM和lowSE64QAM。
在NR系统设计之初，只支持256QAM和64QAM两个MCS表格，其target(目标)BLER(Block Error Rate，误块率)为1e-1，旨在支持eMBB(Enhanced Mobile Broadband，增强移动宽带)业务，后来，为了更好的支持URLLC业务，设计了lowSE64QAM MCS表格，其目标BLER为1e-5。当子载波间隔较小(如子载波间隔为15kHz(千赫兹)，子载波间隔对应的符号/时隙时间较长)，URLLC业务的时延和可靠性要求较高时，这种情况下，由于URLLC业务的时延紧急，无法通过多次重复传输/重传来满足URLLC的高可靠性，而是需要单次传输即满足1e-5的可靠性，因此，lowSE64QAM的MCS表格的目标BLER为1e-5。
在实际的网络实现中，在服务小区的子载波间隔较大(子载波间隔对应的符号/时隙较短)，或者URLLC业务的时延允许重传/重复传输时，网络设备比较典型的调度策略包括：先用目标BLER为1e-1的MCS来调度初传；若初传失败，再用例如目标BLER为1e-5的MCS来调度重传，以保证数据包在两次传输之内正确接收。终端设备可以根据网络设备的配置信息和/或指示信息来确定接收/传输下行数据包/上行数据包所使用的MCS表格。
3、物理层优先级。
在NR系统中，为了更好的支持URLLC业务，对于上行信道在物理层引入了高优先级、低优先级。其中，priority index 0(优先级索引为0)表示低优先级，priority index 1(优先级索引为1)表示高优先级。终端设备可以根据网络设备的配置信息和/或指示信息，确定上行信道(上行信道包括：PUSCH、PUCCH)的优先级索引。
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/n-5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，提出了一种新型的信道状态信息，比如基于PDSCH的解调和/或测量的信道状态信息，或称为“reporting of delta MCS(MCS差值的报告)”。其中，delta MCS为目标MCS和参考MCS之间的差值，目标MCS为使得使用该MCS接收的TB(Transport Block，传输块)的预测BLER(estimated BLER)小于或等于目标BLER的最大MCS。由于信道状态信息是基于PDSCH的解调和/或测量得到的，不需要额外的测量资源与测量时间，因此，基于PDSCH的解调和/或测量的信道状态信息的上报可以降低终端设备得到信道状态信息的计算时延与功耗，同时可以节约CSI-RS资源，使得系统有更多的资源来传输下行数据，提升网络容量。
然而，针对基于PDSCH的解调和/或测量以获取信道状态信息的方式，终端设备如何确定目标BLER以进一步确定目标MCS以及获得通信链路的信道质量，目前却尚未提及和讨论。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。
本申请实施例中，对于目标BLER的确定，考虑了以下两个原则。
(1)目标BLER需要使得delta-MCS的量化开销尽可能小。使得delta-MCS的量化开销尽可能小的方式之一为得到delta-MCS的目标BLER和网络设备调度数据包的BLER尽可能相近。示例性地，如图1所示，如果网络设备调度数据包的BLER和终端设备得到delta-MCS的目标BLER相同的话，delta-MCS的范围就会比较小，相应的量化开销也比较小(或者可以说，在相同开销的情况下，delta-MCS的量化误差小)；如果网络设备调度数据包的BLER和终端设备得到delta-MCS的目标BLER不相同的话，delta-MCS的范围就会比较大，相应的量化开销也比较大(或者可以说，在相同开销的情况下，delta-MCS量化误差大)。
(2)目标BLER应该尽可能和网络设备的下一次调度所使用的BLER匹配，以最小化网络设备基于上报的delta-MCS得到下次调度所使用的MCS的实现算法的复杂度。试想，如果终端设备报告的delta-MCS基于为1e-5的目标BLER，而网络设备下次调度所使用的BLER为1e-1，那么，网络设备需要在MCS选择时，进行目标BLER的折算，这不仅导致额外的算法复杂度，还会由于不同BLER的MCS-SINR(Signal to Interference plus Noise Ratio，信号与干扰加噪声比)曲线的非线性，导致目标BLER折算的准确度也是有折损的。
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。
请参考图2，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。
请参考图3，其示出了本申请一个实施例提供的信息报告方法的流程图，该方法可以应用于上述图2所示的通信系统中。该方法可以包括如下步骤中的至少部分步骤。
步骤310，终端设备基于第一PDSCH相关的信息，确定第一反馈信息；第一反馈信息是基于目标BLER 得到的，目标BLER与第一PDSCH相关的信息相关。
第一PDSCH可以是网络设备通过高层信令配置的PDSCH，可选地，高层信令包括以下至少一项：SIB(System Information Block，系统消息块)、RRC、MAC；或者，第一PDSCH可以是网络设备通过DCI调度的PDSCH。
本申请实施例对第一PDSCH相关的信息的内容不作限定，可选地，第一PDSCH相关的信息包括以下至少一项：第一PDSCH所在的服务小区、第一PDSCH对应的HARQ-ACK(Hybrid Automatic Repeat Request，混合自动重传请求-肯定确认)信息、承载第一PDSCH对应的HARQ-ACK信息的上行信道的优先级索引、第一PDSCH为初传或重传、第一PDSCH对应的NDI(New Data Indication，新数据指示)翻转或未翻转、用于调度或激活第一PDSCH的DCI中的第一指示域，该第一指示域用于指示第一反馈信息基于的目标BLER，也就是说，用于确定第一反馈信息的目标BLER是由第一指示域指示的。
针对第一PDSCH为初传或重传的确定，可以基于第一PDSCH的不同确定方式，来确定第一PDSCH为初传或重传。在一个示例中，第一PDSCH为网络设备通过高层信令配置的PDSCH，则第一PDSCH可以默认为初传。可选地，高层信令包括以下至少一项：SIB、RRC、MAC。在另一个示例中，第一PDSCH为网络设备通过DCI调度的PDSCH，则可以基于该DCI中包含的NDI是否翻转来确定第一PDSCH为初传或重传。可选地，在第一PDSCH对应的NDI(即调度第一PDSCH的DCI中包含的NDI)相对于第一NDI发生翻转的情况下，第一PDSCH为初传；在第一PDSCH对应的NDI相对于第一NDI未发生翻转的情况下，第一PDSCH为重传；其中，第一NDI为承载第一PDSCH的TB的在前传输对应的NDI。或者可以说，在第一PDSCH对应的NDI相对于同一TB的在前传输对应的NDI发生翻转的情况下，第一PDSCH为初传；在第一PDSCH对应的NDI相对于同一TB的在前传输对应的NDI未发生翻转的情况下，第一PDSCH为重传。其中，“同一TB的在前传输”中的“在前传输”，与“第一PDSCH的传输”承载于同一TB中。
有关第一PDSCH相关的信息的其它介绍说明，请参见下述实施例，此处不多赘述。
终端设备基于第一PDSCH相关的信息，可以确定第一反馈信息，该第一反馈信息用于估计通信链路的信道质量和/或信道特性。本申请实施例中，终端设备基于第一PDSCH相关的信息，可以先确定目标BLER，再进一步基于目标BLER确定第一反馈信息。
本申请实施例对第一反馈信息的内容不作限定，在一个示例中，第一反馈信息包括基于第一PDSCH的解调和/或测量得到的信道状态信息；或者，第一反馈信息包括第一差值，第一差值为目标MCS和参考MCS之间的差值。其中，目标MCS是基于目标BLER得到的MCS，终端设备基于第一PDSCH相关的信息，可以先确定目标BLER，再进一步基于目标BLER确定目标MCS，该目标MCS为使得使用该MCS接收的TB的预测BLER小于或等于目标BLER的最大MCS；参考MCS与第一PDSCH对应，或者，参考MCS由网络设备配置，或者，参考MCS由通信协议预定义。可选地，第一PDSCH对应的MCS为调度该第一PDSCH的DCI中包括的MCS。
应理解，“第一反馈信息”这一名称可能会发生变化，例如，“第一反馈信息”也可以称为“信道状态信息”，或者称为“新型的信道状态信息”，或者称为“reporting of delta MCS(MCS差值的报告)”，或者称为“case-2reporting(情况2报告)”。为了便于描述，本申请实施例将基于PDSCH相关的信息得到的、用于估计通信链路的信道质量和/或信道特性的信息，统称为“第一反馈信息”。
有关终端设备基于第一PDSCH相关的信息确定第一反馈信息的其它介绍说明，请参见下述实施例，此处不多赘述。
步骤320，终端设备向网络设备发送第一反馈信息。
终端设备在得到第一反馈信息之后，可以向网络设备发送第一反馈信息，以向网络设备指示通信链路的信道质量和/或信道特性，从而为网络设备进行下行传输等提供参考。可选地，终端设备通过PUCCH资源向网络设备发送第一反馈信息。
本申请实施例对第一反馈信息的上报方式不作限定。在一个示例中，终端设备在向网络设备发送第一反馈信息时，将第一反馈信息作为单独的上行信息上报至网络设备，此时，终端设备可以同时上报第一反馈信息与其它上行信息(如HARQ-ACK码本)，也可以不同时上报第一反馈信息和其它上行信息(如HARQ-ACK码本)。在另一个示例中，终端设备将第一反馈信息与其它的上行信息(如HARQ-ACK码本)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，通过终端设备基于与PDSCH相关的信息确定反馈信息，并向网络设备上报反馈信息，以向网络设备指示通信链路的信道质量和/或信道特性，而不需要额外的针对通信链路的测量资源与测量时间，有助于降低终端设备得到与信道状态相关的信息的计算时延与功耗，同时节约CSI-RS资源，使得通信系统有更多的资源来传输下行数据，提升网络容量。并且，本申请实施例中，反馈信息是基于目标BLER确定的、用于反映信道状态的信息，终端设备可以基于与PDSCH相关的 信息来确定目标BLER，从而提供了一种目标BLER的确定方式。另外，由于目标BLER的确定基于与PDSCH相关的信息，可以实现目标BLER与PDSCH之间的匹配，以确保目标BLER的准确性，从而提升反馈信息的准确性，达到为网络设备提供信道状态的准确指示的效果。
下面，对终端设备基于第一PDSCH确定第一反馈信息的过程进行介绍说明。
在一个示例中，第一PDSCH相关的信息包括：第一PDSCH所在的服务小区；上述步骤310，包括：终端设备基于第一PDSCH所在的服务小区对应的n个参考BLER，确定第一反馈信息，n等于1或者n为大于1的整数。
由于不同的服务小区的激活BWP(Bandwidth Part，带宽部分)的子载波间隔不同，从而即便对于同一种业务，在不同的服务小区上传输所能容忍的传输次数也不同。例如，对于URLLC业务，在子载波间隔为15kHz的服务小区上，只能允许单次传输，也即，网络设备每次调度数据包需要以1e-5的BLER来调度；在子载波间隔为60kHz的服务小区上，可以允许两次传输，也即，网络设备可以先以1e-1的BLER来调度初传，以提高传输效率，若初传错误，再以1e-5的BLER来调度重传，以保证可靠性。基于此，本申请实施例中，对于不同的服务小区设置了不同的参考BLER，通过每个服务小区(per-serving cell)设置参考BLER，可以使得终端设备确定的目标BLER与网络设备调度数据包所使用的BLER尽可能匹配，以减少量化开销。
以第一PDSCH所在的服务小区为例，该第一PDSCH所在的服务小区设置了对应的n个参考BLER。可选地，这n个参考BLER既可以由网络设备配置，如网络设备向终端设备发送n个参考BLER；也可以由通信协议预定义。在一个示例中，参考BLER为BLER，或者说参考BLER为数值，例如，参考BLER为1e-5，或者，参考BLER为1e-1。在另一个示例中，参考BLER为包括至少一个BLER的集合，例如，参考BLER为{1e-1}，或者，参考BLER为{1e-1，1e-5}。
可选地，在第一PDSCH所在的服务小区激活BWP的子载波间隔小于第一阈值的情况下，n个参考BLER均为数值；在第一PDSCH所在的服务小区激活BWP的子载波间隔大于第一阈值的情况下，n个参考BLER中至少一个参考BLER为包括至少一个BLER的集合。本申请实施例对第一阈值不作限定，例如，设置第一阈值为30kHz，假设第一PDSCH所在的服务小区激活BWP的子载波间隔为15kHz，则n个参考BLER可以包括1e-1和1e-5；假设第一PDSCH所在的服务小区激活BWP的子载波间隔为60kHz，则n个参考BLER可以包括{1e-1}和{1e-1，1e-5}。
终端设备基于第一PDSCH所在的服务小区，可以确定第一PDSCH所在的服务小区对应的n个参考BLER，并进一步基于n个参考BLER，确定第一反馈信息。本申请实施例中，终端设备基于n个参考BLER，可以先确定目标BLER，再进一步基于目标BLER确定第一反馈信息。
应理解，本申请实施例中，n可以等于1，此时，第一PDSCH所在的服务小区仅对应一个参考BLER，若该参考BLER为数值或者为仅包括一个BLER的集合，则终端设备可以直接将该参考BLER作为目标BLER；若该参考BLER为包括多个BLER的集合，则终端设备可以进一步基于其它信息从多个BLER中选择一个BLER作为目标BLER，或者终端设备可以从多个BLER中随机选择一个BLER作为目标BLER。本申请实施例中，n也可以大于1，此时，第一PDSCH所在的服务小区对应多个参考BLER，终端设备可以进一步基于其它信息从多个BLER中选择目标BLER。有关终端设备基于其它信息选择目标BLER的过程，请参见下述实施例，此处不多赘述。
在另一个示例中，第一PDSCH相关的信息包括：承载第一PDSCH对应的HARQ-ACK信息的上行信道的优先级索引；上述步骤310，包括：终端设备在上行信道的优先级索引为第一优先级索引的情况下，基于n个参考BLER中的第一参考BLER，确定第一反馈信息；终端设备在上行信道的优先级索引为第二优先级索引的情况下，基于n个参考BLER中的第二参考BLER，确定第一反馈信息。
一种合理的网络设备实现为：对于eMBB业务，网络设备使用1e-1的BLER来进行调度；而对于URLLC业务，网络设备使用1e-5的BLER来进行调度。因此，将目标BLER与物理层优先级相关联，可以使得目标BLER与网络设备调度数据包所使用的BLER尽可能匹配，以减少量化开销。基于此，本申请实施例中，对于不同的物理层优先级设置了不同的参考BLER。
终端设备基于上行信道的优先级索引，可以确定对应的参考BLER，并进一步基于参考BLER确定第一反馈信息。在一个示例中，上行信道的优先级索引为网络设备通过高层信令配置的，该高层信令用于配置第一PDSCH，或者可以说，网络设备在通过高层信令为终端设备配置第一PDSCH时，同时通过该高层信令配置承载第一PDSCH对应的HARQ-ACK信息的上行信道的优先级索引。可选地，高层信令包括以下至少一项：SIB、RRC、MAC。在另一个示例中，上行信道的优先级索引为网络设备通过DCI指示的，DCI用于调度或激活第一PDSCH。
本申请实施例中，上行信道的优先级索引包括第一优先级索引和第二优先级索引，在上行信道的优先 级索引为第一优先级索引的情况下，终端设备从n个参考BLER中确定第一优先级索引对应的第一参考BLER，并进一步基于第一参考BLER确定第一反馈信息；在上行信道的优先级索引为第二优先级索引的情况下，终端设备从n个参考BLER中确定第二优先级索引对应的第二参考BLER，并进一步基于第二参考BLER确定第一反馈信息。
应理解，本申请实施例中，n可以等于1，此时，第一参考BLER与第二参考BLER相同，也即，无论上行信道的优先级索引为哪一种优先级索引，终端设备均基于相同的参考BLER确定第一反馈信息。本申请实施例中，n也可以大于1，此时，第一参考BLER与第二参考BLER实现为n个参考BLER中的不同参考BLER，也即，上行信道的优先级索引不同，终端设备即基于不同的参考BLER确定第一反馈信息。
此外，本申请实施例中，第一参考BLER/第二参考BLER可以是一个数值或者为仅包括一个BLER的集合，从而终端设备可直接将第一参考BLER/第二参考BLER作为目标BLER，并进一步基于目标BLER确定第一反馈信息。本申请实施例中，第一BLER/第二BLER也可以是包括多个BLER的集合，从而终端设备可以进一步基于其它信息从这多个BLER中选择一个BLER作为目标BLER，或者，终端设备可以从这多个BLER中随机选择一个BLER作为目标BLER。有关终端设备基于其它信息选择目标BLER的过程，请参见下述实施例，此处不多赘述。
以第一参考BLER和第二参考BLER均为数值为例，假设第一优先级索引对应的物理层优先级高于第二优先级索引对应的物理层优先级，则终端设备基于第一优先级索引确定的第一参考BLER小于第二参考BLER；假设第一优先级索引对应的物理层优先级低于第二优先级索引对应的物理层优先级，则终端设备基于第一优先级索引确定的第一参考BLER大于第二参考BLER。例如，假设第一优先级索引为上述priority index 1，第二优先级索引为上述priority index 0，则第一参考BLER为1e-5，第二参考BLER为1e-1；假设第一优先级索引为上述priority index 0，第二优先级索引为上述priority index 1，则第一参考BLER为1e-1，第二参考BLER为1e-5。
以第一参考BLER为数值或集合、第二参考BLER为数值或集合为例，假设第一优先级索引对应的物理层优先级高于第二优先级索引对应的物理层优先级，则终端设备基于第一优先级索引确定的第一参考BLER小于或等于第二参考BLER；假设第一优先级索引对应的物理层优先级低于第二优先级索引对应的物理层优先级，则终端设备基于第一优先级索引确定的第一参考BLER大于或等于第二参考BLER。例如，假设第一优先级索引为上述priority index 1，第二优先级索引为上述priority index 0，则第一参考BLER为{1e-1，1e-5}，第二参考BLER为{1e-1}或1e-1；假设第一优先级索引为上述priority index 0，第二优先级索引为上述priority index 1，则第一参考BLER为{1e-1}或1e-1，第二参考BLER为{1e-1，1e-5}。
在再一个示例中，第一PDSCH相关的信息包括：用于调度或激活第一PDSCH的DCI中的第一指示域；上述步骤310，包括：终端设备在第一指示域的取值为第i个取值的情况下，基于n个参考BLER中的第i个参考BLER，确定第一反馈信息；i为小于或等于n的正整数。
第一PDSCH可以是网络设备通过DCI调度的PDSCH，本示例中，DCI中的第一指示域可以用于指示确定第一反馈信息基于的目标BLER。该第一指示域可以是复用DCI中已有的信息域，也可以是DCI中新定义的信息域，本申请实施例对此不作限定。该第一指示域的比特数可以为1比特，也可以为多比特，如2比特、3比特、4比特等，本申请实施例对此也不限定。示例性地，第一指示域为1比特，则第一指示域的取值可以为0或1；第一指示域为2比特，则第一指示域的取值可以为00、01、10、11。
通过第一指示域的不同取值，可以指示不同的BLER。假设设置了n个参考BLER，则第一指示域的取值个数大于或等于n。例如，设置了2个参考BLER，第一指示域为1比特，第一指示域的取值个数为2个，则可以将这2个取值分别与2个参考BLER关联。又例如，设置了3个参考BLER，第一指示域为2比特，第一指示域的取值个数为4个，其中3个取值分别与3个参考BLER关联，另外一个取值可以设置指示默认参考BLER，或者被复用为指示其它信息等。
在第一指示域的取值为第i个取值(或者可以说，第一指示域的取值为第一指示域的所有取值情况中的第i个取值)的情况下，终端设备基于n个参考BLER中与第i个取值对应的第i个参考BLER，确定第一反馈信息。示例性地，第一指示域的取值包括第一值和第二值，则在第一指示域的取值为第一值的情况下，终端设备可以基于n个参考BLER中的第一参考BLER，确定第一反馈信息；在第一指示域的取值为第二值的情况下，终端设备可以基于n个参考BLER中的第二参考BLER，确定第一反馈信息。
以终端设备确定的第i个参考BLER为数值或者为仅包括一个BLER的集合为例，终端设备基于第一指示域的第i个取值，可以将n个参考BLER中与第i个取值对应的第i个参考BLER作为目标BLER，并进一步基于目标BLER确定第一反馈信息。
以终端设备确定的第i个参考BLER为包括多个BLER的集合为例，终端设备基于第一指示域的第i个取值，确定n个参考BLER中与该第i个取值对应的第i个参考BLER，而由于第i个参考BLER为包括多个BLER的集合，则终端设备可以基于其它信息进一步从多个BLER中选择一个BLER作为目标BLER， 或者，终端设备可以从多个BLER中随机选择一个BLER作为目标BLER。有关终端设备基于其它信息选择目标BLER的过程，请参见下述实施例，此处不多赘述。
在又一个示例中，第一PDSCH相关的信息包括：第一PDSCH对应的HARQ-ACK信息；上述步骤310，包括：终端设备在第一PDSCH对应的HARQ-ACK信息为ACK的情况下，基于n个参考BLER中的第一参考BLER，确定第一反馈信息；终端设备在第一PDSCH对应的HARQ-ACK信息为NACK(Negative Acknowledgement，否定确认)的情况下，基于n个参考BLER中的第二参考BLER，确定第一反馈信息。
针对接收到的PDSCH，终端设备需要向网络设备上报PDSCH的HARQ-ACK信息。由于PDSCH的HARQ-ACK信息可以为ACK，也可以为NACK，从而可以将HARQ-ACK信息的不同内容与不同的参考BLER关联。
本申请实施例中，在第一PDSCH对应的HARQ-ACK信息为ACK的情况下，终端设备基于n个参考BLER中与ACK对应的第一参考BLER，确定第一反馈信息；在第一PDSCH对应的HARQ-ACK信息为NACK的情况下，终端设备基于n个参考BLER中与NACK对应的第二参考BLER，确定第一反馈信息。
应理解，本申请实施例中，第一参考BLER/第二参考BLER可以是一个数值或者为仅包括一个BLER的集合，从而终端设备可直接将第一参考BLER/第二参考BLER作为目标BLER，并进一步基于目标BLER确定第一反馈信息。本申请实施例中，第一BLER/第二BLER也可以是包括多个BLER的集合，从而终端设备可以进一步基于其它信息从这多个BLER中选择一个BLER作为目标BLER，或者，终端设备可以从这多个BLER中随机选择一个BLER作为目标BLER。有关终端设备基于其它信息选择目标BLER的过程，请参见下述实施例，此处不多赘述。
以子载波间隔为60kHz的服务小区为例，即便是存在URLLC业务低时延的需求，也可以容忍两次传输(初传+重传)，那么一种合理的网络设备实现为：对于初传，使用1e-1的BLER来提升谱效，若初传失败，再以1e-5的BLER调度重传保证数据包的可靠性。在HARQ-ACK信息为ACK的情况下，表示本次数据包终端设备已接收正确，网络设备下次调度下一个数据包的初传，从而ACK对应的BLER可以为1e-1；在HARQ-ACK信息为NACK的情况下，表示本次数据包终端设备未正确接收，网络设备下次调度本次数据包的重传，则NACK对应的BLER可以为1e-5。通过基于HARQ-ACK来确定目标BLER，可以使得目标BLER和网络设备下一次调度所使用的BLER更加匹配，以最小化网络设备根据上报的第一反馈信息得到下次调度所使用的MCS的实现算法的复杂度。
基于此，HARQ-ACK信息为ACK时所基于的第一参考BLER，大于或等于HARQ-ACK信息为NACK时所基于的第二参考BLER。例如，HARQ-ACK信息为ACK，终端设备将1e-1(第一参考BLER)作为目标BLER；HARQ-ACK信息为NACK，终端设备将1e-5(第二参考BLER)作为目标BLER。又例如，HARQ-ACK信息为ACK，终端设备将1e-1或{1e-1}(第一参考BLER)作为目标BLER；HARQ-ACK信息为NACK，终端设备基于{1e-1，1e-5}进一步确定目标BLER。
在还一个示例中，第一PDSCH相关的信息包括：第一PDSCH为初传或重传，和/或，第一PDSCH对应的NDI翻转或未翻转；上述步骤310，包括：终端设备在第一PDSCH为初传，和/或，第一PDSCH对应的NDI翻转的情况下，基于n个参考BLER中的第一参考BLER，确定第一反馈信息；终端设备在第一PDSCH为重传，和/或，第一PDSCH对应的NDI未翻转的情况下，基于n个参考BLER中的第二参考BLER，确定第一反馈信息。
第一PDSCH中承载的数据可能为初传数据，也可能为重传数据，从而可以将第一PDSCH为初传或重传这两种不同的情况，与不同的参考BLER关联。有关第一PDSCH为初传或重传的确定方式，请参见上述实施例，此处不多赘述。应理解，在第一PDSCH为DCI调度的PDSCH的情况下，第一PDSCH为初传或重传，也可以称为第一PDSCH对应的NDI翻转或未翻转，这两种表述应当具有相同的含义。
本申请实施例中，在第一PDSCH为初传，和/或，第一PDSCH对应的NDI翻转的情况下，终端设备基于n个参考BLER中第一参考BLER确定第一反馈信息；在第一PDSCH为重传，和/或，第一PDSCH对应的NDI未翻转的情况下，终端设备基于n个参考BLER中第二参考BLER确定第一反馈信息。
应理解，本申请实施例中，第一参考BLER/第二参考BLER可以是一个数值或者为仅包括一个BLER的集合，从而终端设备可直接将第一参考BLER/第二参考BLER作为目标BLER，并进一步基于目标BLER确定第一反馈信息。本申请实施例中，第一BLER/第二BLER也可以是包括多个BLER的集合，从而终端设备可以进一步基于其它信息从这多个BLER中选择一个BLER作为目标BLER，或者，终端设备可以从这多个BLER中随机选择一个BLER作为目标BLER。有关终端设备基于其它信息选择目标BLER的过程，请参见下述实施例，此处不多赘述。
针对PDSCH可以有多次传输(初传+重传)，网络设备的一种实现方式为：使用1e-1的BLER调度初传来提升谱效，若初传失败，再以1e-5的BLER调度重传以保证数据包的可靠性。通过基于PDSCH为初传或重传(或者说基于PDSCH对应的NDI翻转或未翻转)来确定目标BLER，可以使得目标BLER与网 络设备调度PDSCH所使用的BLER尽可能匹配，减少量化开销。
基于此，第一PDSCH为初传和/或第一PDSCH对应的NDI翻转时终端设备所基于的第一参考BLER，大于或等于第一PDSCH为重传和/或第一PDSCH对应的NDI未翻转时终端设备所基于的第二BLER。例如，第一PDSCH为初传，和/或，第一PDSCH对应的NDI翻转，终端设备将1e-1(第一参考BLER)作为目标BLER；第一PDSCH为重传，和/或，第一PDSCH对应的NDI未翻转，终端设备将1e-5(第二参考BLER)作为目标BLER。又例如，第一PDSCH为初传，和/或，第一PDSCH对应的NDI翻转，终端设备将1e-1或{1e-1}(第一参考BLER)作为目标BLER；第一PDSCH为重传，和/或，第一PDSCH对应的NDI未翻转，终端设备基于{1e-1，1e-5}进一步确定目标BLER。
在上述示例中，终端设备再基于n个参考BLER确定目标BLER时，由于参考BLER可能为包括多个BLER的集合，从而终端设备需要进一步从多个BLER中选择目标BLER。基于此，本申请实施例以终端设备基于HARQ-ACK信息、第一PDSCH为初传或重传等信息为例，介绍说明如何从多个BLER中选择目标BLER。
在一个示例中，第一PDSCH相关的信息包括：第一PDSCH对应的HARQ-ACK信息；上述步骤310，包括：终端设备在第一PDSCH对应的HARQ-ACK信息为ACK的情况下，基于第三参考BLER中的第一BLER，确定第一反馈信息；终端设备在第一PDSCH对应的HARQ-ACK信息为NACK的情况下，基于第三参考BLER中的第二BLER，确定第一反馈信息。
第三参考BLER为包括多个BLER的集合，该第三参考BLER可以为上述第一参考BLER，也可以为上述第二参考BLER。为了便于描述，在本示例中，将包括多个BLER的集合称为第三参考BLER。第三参考BLER中不同的BLER与HARQ-ACK信息的不同内容相关联。
在第一PDSCH对应的HARQ-ACK信息为ACK的情况下，终端设备基于第三参考BLER中的第一BLER，确定第一反馈信息；在第一PDSCH对应的HARQ-ACK信息为NACK的情况下，终端设备基于第三参考BLER中的第二BLER，确定第一反馈信息。换句话说，终端设备基于第一PDSCH对应的HARQ-ACK信息的内容，从第三参考BLER中选择一个BLER作为目标BLER，并进一步基于目标BLER确定第一反馈信息。
由上述示例可知，HARQ-ACK信息为ACK时，网络设备可以使用较大的BLER来提升谱效；HARQ-ACK信息为NACK时，网络设备可以使用较小的BLER来确保数据包的可靠性。基于此，ACK对应的第一BLER大于NACK对应的第二BLER。例如，HARQ-ACK信息为ACK时，终端设备将1e-1(第一BLER)作为目标BLER；HARQ-ACK信息为NACK时，终端设备将1e-5(第二BLER)作为目标BLER。
在另一个示例中，第一PDSCH相关的信息包括：第一PDSCH为初传或重传，和/或，第一PDSCH对应的NDI翻转或未翻转；上述步骤310，包括：终端设备在第一PDSCH为初传，和/或，第一PDSCH对应的NDI翻转的情况下，基于第三参考BLER中的第一BLER，确定第一反馈信息；终端设备在第一PDSCH为重传，和/或，第一PDSCH对应的NDI未翻转的情况下，基于第三参考BLER中的第二BLER，确定第一反馈信息。
第三参考BLER为包括多个BLER的集合，该第三参考BLER可以为上述第一参考BLER，也可以为上述第二参考BLER。为了便于描述，在本示例中，将包括多个BLER的集合称为第三参考BLER。第三参考BLER中不同的BLER与HARQ-ACK信息的不同内容相关联。
在第一PDSCH为初传和/或第一PDSCH对应的NDI翻转的情况下，终端设备基于第三参考BLER中的第一BLER，确定第一反馈信息；在第一PDSCH为重传和/或第一PDSCH对应的NDI未翻转的情况下，终端设备基于第三参考BLER中的第二BLER，确定第一反馈信息。换句话说，终端设备基于第一PDSCH为初传或重传和/或第一PDSCH对应的NDI翻转或未翻转，从第三参考BLER中选择一个BLER作为目标BLER，并进一步基于目标BLER确定第一反馈信息。
由上述示例可知，网络设备使用较大的BLER调度初传来提升谱效，若初传失败，网络设备使用较小的BLER调度重传以保证数据包的可靠性。基于此，第一PDSCH为初传和/或第一PDSCH对应的NDI翻转所对应的第一BLER，大于第一PDSCH为重传和/或第一PDSCH对应的NDI未翻转所对应的第二BLER。例如，第一PDSCH为初传和/或第一PDSCH对应的NDI翻转时，终端设备将1e-1(第一BLER)作为目标BLER；第一PDSCH为重传和/或第一PDSCH对应的NDI未翻转时，终端设备将1e-5(第二BLER)作为目标BLER。
综上所述，本申请实施例提供的技术方案，通过PDSCH相关的多种信息，如PDSCH所在的服务小区、PDSCH对应的HARQ-ACK信息、承载PDSCH对应的HARQ-ACK信息的上行信道的优先级索引、调度PDSCH的DCI中的第一指示域、PDSCH为初传或重传、PDSCH对应的NDI翻转或未翻转，来确定信道状态的反馈信息基于的目标BLER，充分考虑了影响传输效率和传输可靠性等的因素，有助于减少量化开销，且有助于最小化网络设备确定调度数据包所使用的MCS的实现算法的复杂度。
需要说明的一点是，本申请实施例中，终端设备可以结合上述第一PDSCH相关的多种信息来确定第一反馈信息基于的目标BLER。下面，以一个示例，对结合第一PDSCH相关的多种信息确定目标BLER的方案进行介绍说明。
在一个示例中，网络设备为终端设备配置了两个服务小区，分别为服务小区1和服务小区2。其中，服务小区1激活BWP的子载波间隔为15kHz，服务小区2激活BWP的子载波间隔为60kHz。
假设服务小区1设置了两个参考BLER，分别为1e-1和1e-5，其中，1e-1对应的上行信道的优先级索引为priority index 0，1e-5对应的上行信道的优先级索引为priority index 1。
假设服务小区2设置了两个参考BLER，分别为{1e-1}和{1e-1，1e-5}，{1e-1}对应的上行信道的优先级索引为priority index 0，{1e-1，1e-5}对应的上行信道的优先级索引为priority index 1。
以第一PDSCH所在的服务小区为服务小区1为例，终端设备在承载第一PDSCH对应的HARQ-ACK信息的上行信道的优先级索引为priority index 0的情况下，确定目标BLER为1e-1；终端设备在承载第一PDSCH对应的HARQ-ACK信息的上行信道的优先级索引为priority index 1时，确定目标BLER为1e-5。
以第一PDSCH所在的服务小区为服务小区2为例，终端设备在承载第一PDSCH对应的HARQ-ACK信息的上行信道的优先级索引为priority index 0的情况下，确定目标BLER为1e-1；终端设备在承载第一PDSCH对应的HARQ-ACK信息的上行信道的优先级索引为priority index 1时，基于{1e-1，1e-5}进一步确定目标BLER。此时，终端设备可以通过如下任意一种方式确定目标BLER。
(1)终端设备基于第一PDSCH对应的HARQ-ACK信息确定目标BLER。终端设备在第一PDSCH对应的HARQ-ACK信息为ACK的情况下，将{1e-1，1e-5}中的1e-1作为目标BLER；终端设备在第一PDSCH对应的HARQ-ACK信息为NACK的情况下，将{1e-1，1e-5}中的1e-5作为目标BLER。
(2)终端设备基于第一PDSCH为初传或重传，和/或，第一PDSCH对应的NDI翻转或未翻转，来确定目标BLER。终端设备在第一PDSCH为初传和/或第一PDSCH对应的NDI翻转的情况下，将{1e-1，1e-5}中的1e-1作为目标BLER；终端设备在第一PDSCH为重传和/或第一PDSCH对应的NDI未翻转的情况下，将{1e-1，1e-5}中的1e-5作为目标BLER。
下面，对终端设备确定第一反馈信息的方式进行介绍说明。
在一个示例中，上述方法还包括：终端设备基于第二差值和目标参考差值集合，确定第一反馈信息。
第二差值是基于目标BLER得到的，且第二差值为目标MCS和参考MCS之间的差值。其中，目标MCS是基于目标BLER得到的MCS，有关目标BLER的确定过程请参见上述实施例，此处不多赘述；参考MCS与第一PDSCH对应，或者，参考MCS由网络设备配置，或者，参考MCS由通信协议预定义。可选地，第一PDSCH对应的MCS为调度该第一PDSCH的DCI中包括的MCS。
本申请实施例中，终端设备可以基于第二差值和目标参考差值集合，确定第一反馈信息。该目标参考差值集合包括至少一个参考差值，该参考差值包括第二差值。可选地，目标参考差值集合中的参考差值可以为数值，也可以为差值范围。例如，目标参考差值集合为{≤-2，-1，0，≥1}。
可选地，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，由通信协议预定义或者由网络设备配置有相应的反馈信息，进而终端设备可以确定第二差值在目标参考差值集合中对应的位置，以进一步确定第二差值对应的第一反馈信息。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反馈信息，该高层信令包括以下至少一项：SIB、RRC、MAC。当然，目标参考差值集合中的参考差值对应的反馈信息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反馈信息，应理解，这些确定方式均应属于本申请的保护范围之内。
示例性地，对于目标参考差值集合为{≤-2，-1，0，≥1}，其中，参考差值为≤-2对应于第一反馈信息为00，参考差值为-1对应于第一反馈信息为01，参考差值为0对应于第一反馈信息为10，参考差值为≥1对应于第一反馈信息为11。
应理解，本申请实施例中的第二差值和第一差值在表达的含义上是相同的，均用于表示目标MCS和参考MCS之间的差值；但是，第二差值和第一差值在表现的形式上可能是不相同的，例如，目标MCS为4，参考MCS为3，则第二差值可以为4-3＝1，进一步地，基于第二差值在目标参考差值集合中对应的参考差值，确定第一差值为11，则包括第一差值的第一反馈信息即为11。
在另一个示例中，上述方法还包括：终端设备基于第一值和目标参考差值集合，确定第一反馈信息；第一值是终端设备基于第二差值和目标偏移值得到的。
本示例中，终端设备在确定了第二差值之后，先基于第二差值和目标偏移值确定第一值，再进一步基于第一值和目标参考差值集合，确定第一反馈信息。可选地，终端设备在第二差值的基础上，加上目标偏 移值，或者减去目标偏移值，或者乘以目标偏移值等，得到第一值。有关目标参考差值集合、基于第一值和目标参考差值集合确定第一反馈信息的其它内容，请参见上述实施例，此处不多赘述。
在上述实施例中，涉及到目标参考差值集合和目标偏移值，终端设备可以从至少一个参考差值集合中确定目标参考差值集合、从至少一个偏移值中确定目标偏移值。可选地，至少一个参考差值集合由网络设备配置；或者，至少一个参考差值集合由通信协议预定义。可选地，至少一个偏移值由网络设备配置；或者，至少一个偏移值由通信协议预定义。本申请实施例对终端设备确定目标参考差值集合、目标偏移值的方式不作限定，下面，示例性地示出了几种确定方式。
在一个示例中，终端设备基于DCI中的第二指示域，确定第一反馈信息。该DCI用于调度或激活第一PDSCH，该DCI中的第二指示域用于确定第一反馈信息基于的目标参考差值集合和/或基于的目标偏移值，或者可以说，DCI中的第二指示域用于指示目标参考差值集合和/或目标偏移值。可选地，第二指示域可以是DCI中新定义的指示域，也可以是复用DCI中已定义的指示域，本申请实施例对此不作限定。可选地，第二指示域的比特数可以为1比特，也可以为多比特，如2比特、3比特等，本申请实施例对此不作限定。
结合上述实施例，在基于第二差值和目标参考差值集合确定第一反馈信息的情况下，终端设备基于DCI中的第二指示域，从至少一个参考差值集合中确定目标参考差值集合；在基于第二差值和目标偏移值得到第一值，并基于第一值和目标参考差值集合确定第一反馈信息的情况下，终端设备基于DCI中的第二指示域，从至少一个偏移值中确定目标偏移值，和/或，从至少一个参考差值集合中确定目标参考差值集合。
示例性地，在第二指示域的取值为第一数值时，终端设备基于至少一个参考差值集合中的第一参考差值集合，确定第一反馈信息(或者说，终端设备可以将至少一个参考差值集合中的第一参考差值集合确定为目标参考差值集合，并基于目标参考差值集合确定第一反馈信息)；或者，终端设备基于至少一个偏移值中的第一偏移值，确定第一反馈信息(或者说，终端设备可以将至少一个偏移值中的第一偏移值确定为目标偏移值，并基于目标偏移值确定第一反馈信息)；或者，终端设备不基于至少一个偏移值确定第一反馈信息(或者说，终端设备直接基于第二差值和目标参考差值集合，确定第一反馈信息)。
示例性地，在第二指示域的取值为第二数值时，终端设备基于至少一个参考差值集合中的第二参考差值集合，确定第一反馈信息(或者说，终端设备可以将至少一个参考差值集合中的第二参考差值集合确定为目标参考差值集合，并基于目标参考差值集合确定第一反馈信息)；或者，终端设备基于至少一个偏移值中的第二偏移值，确定第一反馈信息(或者说，终端设备可以将至少一个偏移值中的第二偏移值确定为目标偏移值，并基于目标偏移值确定第一反馈信息)。
示例性地，在第二指示域的取值为第三数值时，终端设备基于至少一个参考差值集合中的第三参考差值集合，确定第一反馈信息(或者说，终端设备可以将至少一个参考差值集合中的第三参考差值集合确定为目标参考差值集合，并基于目标参考差值集合确定第一反馈信息)；或者，终端设备基于至少一个偏移值中的第三偏移值，确定第一反馈信息(或者说，终端设备可以将至少一个偏移值中的第三偏移值确定为目标偏移值，并基于目标偏移值确定第一反馈信息)。
有关至少一个参考差值集合包括三个以上的参考差值集合、至少一个偏移值包括三个以上的偏移值的情况下，终端设备如何基于第二指示域的取值来确定第一反馈信息的介绍说明，可以基于上述示例类推得到，此处不再赘述。
例如，至少一个参考差值集合分别为{≤-2，-1，0，≥1}、{≤1，2，3，≥4}、{≤-5，-4，-3，≥-2}，至少一个偏移值分别为0、+3、-3或者为+3、-3。假设第二指示域为2比特，则第二指示域的取值可能为00、01、10、11。其中，第二指示域为00时，终端设备将{≤-2，-1，0，≥1}确定为目标参考差值集合，或者，将0确定为目标偏移值，或者，不使用至少一个偏移值确定第一反馈信息；在第二指示域为01时，终端设备将{≤1，2，3，≥4}确定为目标参考差值集合，或者，将+3确定为目标偏移值；在第二指示域为10时，终端设备将{≤-5，-4，-3，≥-2}确定为目标参考差值集合，或者，将-3确定为目标偏移值；在第二指示域为11时，该第二指示域为缺省。
在另一个示例中，终端设备基于第一规则，确定第一反馈信息。该第一规则用于确定第一反馈信息基于的目标参考差值集合和/或基于的目标偏移值。
结合上述实施例，在基于第二差值和目标参考差值集合确定第一反馈信息的情况下，终端设备基于第一规则，从至少一个参考差值集合中确定目标参考差值集合；在基于第二差值和目标偏移值得到第一值，并基于第一值和目标参考差值集合确定第一反馈信息的情况下，终端设备基于第一规则，从至少一个偏移值中确定目标偏移值，和/或，从至少一个参考差值集合中确定目标参考差值集合。
本申请实施例对第一规则的具体内容不作限定，可选地，第一规则可以通过第一PDSCH相关的信息 来确定目标参考差值集合和/或目标偏移值。有关第一PDSCH相关的信息的介绍说明，请参见上述实施例，此处不多赘述。下面，以第一规则通过第一PDSCH为初传或重传、第一PDSCH对应的NDI翻转或未翻转、第一PDSCH对应的HARQ-ACK信息为例，对第一规则的内容进行介绍说明。
首先，基于第一PDSCH为初传或重传、第一PDSCH对应的NDI翻转或未翻转、第一PDSCH对应的HARQ-ACK信息，可以划分出如下几种情况。
(1)第一PDSCH为初传和/或第一PDSCH对应的NDI翻转，且第一PDSCH对应的HARQ-ACK信息为ACK；或者，第一PDSCH为重传和/或第一PDSCH对应的NDI未翻转，且第一PDSCH对应的HARQ-ACK信息为NACK；第一PDSCH为初传和/或第一PDSCH对应的NDI翻转，和/或，第一PDSCH对应的HARQ-ACK信息为ACK；或者，第一PDSCH为重传和/或第一PDSCH对应的NDI未翻转，和/或，第一PDSCH对应的HARQ-ACK信息为NACK。
(2)第一PDSCH为初传和/或第一PDSCH对应的NDI翻转，且第一PDSCH对应的HARQ-ACK信息为NACK；或者，第一PDSCH为初传和/或第一PDSCH对应的NDI翻转，和/或，第一PDSCH对应的HARQ-ACK信息为NACK。
(3)第一PDSCH为重传和/或第一PDSCH对应的NDI未翻转，且第一PDSCH对应的HARQ-ACK信息为ACK；或者，第一PDSCH为重传和/或第一PDSCH对应的NDI未翻转，和/或，第一PDSCH对应的HARQ-ACK信息为ACK。
针对情况(1)，网络设备调度数据包所使用的BLER与目标BLER相同(如均为1e-1或均为1e-5)，此时，终端设备基于至少一个参考差值集合中的第一参考差值集合，确定第一反馈信息(或者说，终端设备可以将至少一个参考差值集合中的第一参考差值集合确定为目标参考差值集合，并基于目标参考差值集合确定第一反馈信息)；或者，终端设备基于至少一个偏移值中的第一偏移值，确定第一反馈信息(或者说，终端设备可以将至少一个偏移值中的第一偏移值确定为目标偏移值，并基于目标偏移值确定第一反馈信息)；或者，终端设备不基于至少一个偏移值确定第一反馈信息(或者说，终端设备直接基于第二差值和目标参考差值集合，确定第一反馈信息)。
针对情况(2)，网络设备调度数据包所使用的BLER大于目标BLER(如网络设备调度数据包所使用的BLER为1e-1，目标BLER为1e-5)，此时，终端设备基于至少一个参考差值集合中的第二参考差值集合，确定第一反馈信息(或者说，终端设备可以将至少一个参考差值集合中的第二参考差值集合确定为目标参考差值集合，并基于目标参考差值集合确定第一反馈信息)；或者，终端设备基于至少一个偏移值中的第二偏移值，确定第一反馈信息(或者说，终端设备可以将至少一个偏移值中的第二偏移值确定为目标偏移值，并基于目标偏移值确定第一反馈信息)。
针对情况(3)，网络设备调度数据包所使用的BLER小于目标BLER(如网络设备调度数据包所使用的BLER为1e-5，目标BLER为1e-1)，此时，终端设备基于至少一个参考差值集合中的第三参考差值集合，确定第一反馈信息(或者说，终端设备可以将至少一个参考差值集合中的第三参考差值集合确定为目标参考差值集合，并基于目标参考差值集合确定第一反馈信息)；或者，终端设备基于至少一个偏移值中的第三偏移值，确定第一反馈信息(或者说，终端设备可以将至少一个偏移值中的第三偏移值确定为目标偏移值，并基于目标偏移值确定第一反馈信息)。
综上所述，本申请实施例提供的技术方案，通过提供多种方式确定信道状态的反馈信息，终端设备既可以基于目标MCS和参考MCS的差值和目标参考差值集合确定反馈信息，也可以基于第一值和目标参考差值集合确定反馈信息，提升了反馈信息的确定灵活性。并且，本申请实施例中，通过终端设备先基于目标MCS和参考MCS的差值和偏移值确定第一值，再基于第一值和目标参考差值集合确定反馈信息，可以有效减少针对参考差值集合的配置或定义，有助于节约系统的处理资源，提升反馈信息的确定效率。
