  • 5G next-generation mobile communication system
  • 5G base stations are heavily considering using a greater number of antennas and larger-dimensional antenna arrays.
  • larger-dimensional antenna arrays can enhance beam coverage and simultaneously serve the data needs of more users.
  • CSI measurement reporting only supports the reception, measurement, and reporting of CSI-RS (Channel State Information Reference Signal) resources on a maximum of 32 ports.

Furthermore, extending the existing CSI measurement reporting framework is very challenging, especially given the exponentially increased CSI reporting and feedback resulting from the expansion of antenna ports. Therefore, the current standard urgently needs to enhance the existing standard scheme.

  • terminal devices In mobile communication systems, terminal devices typically perform CSI measurements according to the instructions and configurations of network devices, and then report the measured CSI to the network devices.
  • the network devices can refer to the CSI to schedule the terminal device to transmit using appropriate transmission methods on suitable physical resources. Different terminal devices may experience different physical channel conditions; using a CSI feedback mechanism can make reasonable and effective use of physical resources, thereby improving the overall network transmission efficiency.
  • NR's CSI feedback mechanism terminal devices primarily measure reference signals and report the results based on CSI configuration.
  • Reference signals include CSI-RS and SSB, among others.
  • NR's CSI configuration mainly consists of two parts: first, the network device configures the reference signal resources for CSI measurements for the terminal device (CSI-RS resource configuration); second, the network device configures how the terminal device reports the results (CSI reporting settings). While the underlying principles of these two configurations are relatively simple, the specific details of the protocol are quite complex. This section only introduces the details relevant to this application.
  • CSI-RS resource settings can be used for interference measurements and CSI channel measurements.
  • Each resource setting contains S resource sets.
  • Each resource set contains Ks CSI-RS resources.
  • a non-periodic resource setting can contain one or more resource sets. For periodic and semi-persistent resource settings used for CSI acquisition, only one resource set can be included.
  • Type II has relatively high computational complexity, posing a significant challenge to the terminal equipment's computation. Therefore, the NR system limits the value of Ks to relatively reduce the computational complexity of the terminal equipment.
  • CSI reports are associated with CSI resources (used for measurement).
  • CSI reports can be configured into three types: Periodic CSI reports (P-CSI), transmitted only on the Physical Uplink Control Channel (PUCCH); Semi-persistent CSI reports (SP-CSI), transmitted on either the PUCCH or the Physical Uplink Shared Channel (PUSCH); and Aperiodic CSI reports (AP-CSI), transmitted only on the PUSCH.
  • Periodic CSI reports can only be associated with periodic CSI-RS
  • semi-persistent CSI reports can be associated with both periodic and semi-persistent CSI-RS
  • aperiodic CSI reports can be associated with periodic, semi-persistent, and aperiodic CSI-RS.
  • Periodic CSI reporting can only use Periodic CSI-RS for channel measurements and Periodic CSI-IM for interference measurements; it does not support interference measurements using NZP CSI-RS.
  • each periodic CSI reporting setting (or CSI reporting config) is associated with a resource setting containing only one set of CSI-RS resources. The QCL information for each CSI-RS resource is determined by the TCI state of this resource setting.
  • SP-CSI Semi-Continuous CSI Reporting
  • SP-CSI can use Periodic CSI-RS or SP-CSI-RS for channel measurements, and correspondingly use Periodic CSI-IM or SP-CSI-IM for interference measurements.
  • NZP CSI-RS is not supported for interference measurements.
  • SP-CSI can be reported based on either PUSCH or PUCCH.
  • PUSCH-based SP-CSI is more similar to aperiodic CSI reporting, with dynamically allocated feedback resources; while PUCCH-based SP-CSI is more similar to periodic CSI reporting, with semi-static feedback resource indication. Therefore, these two feedback methods employ different activation and deactivation mechanisms.
  • each CSI reporting setting is associated with a resource setting containing only one CSI-RS resource set.
  • SP-CSI activation and deactivation can be achieved using DCI format 0_1 scrambled with SP-CSI C-RNTI.
  • the SP-CSI feedback slot offset is indicated by DCI.
  • This feedback slot offset represents the number of slots from DCI activation to SP-CSI reporting.
  • the DCI indicates a slot offset of Y
  • the first SP-CSI reporting slot is n+Y
  • the second SP-CSI reporting slot is n+Y+P
  • P represents the SP-CSI feedback period.
  • the candidate value for this feedback slot Y is configured by RRC signaling in the CSI reporting settings.
  • activation and deactivation can be performed by MAC CE.
  • RRC configures multiple SP CSI report settings, and each report setting is configured with multiple PUCCH resources, with one PUCCH resource configured for each candidate UL BWP.
  • MAC CE activates only one report setting at a time.
  • PUCCH resources are semi-statically allocated; therefore, the SP-CSI feedback period and slot offset are configured by RRC in the report settings. This represents the system's absolute slot position and is independent of the MAC CE activation time.
  • Aperiodic CSI reporting is configured and triggered using MAC CE combined with DCI, and reported based on PUSCH.
  • the RRC configures multiple CSI trigger states; unlike SP-CSI reporting, each CSI trigger state can correspond to one or more report settings.
  • a report setting is triggered by the CSI request field in the DCI.
  • the size of the CSI request field in DCI format 0_1 can be configured from 0 to 6 bits by RRC signaling, thus indicating a maximum of 64 CSI trigger states.
  • MAC CE signaling maps 64 of these CSI trigger states to the CSI request field indication.
  • Aperiodic CSI reporting can use periodic, semi-persistent, or aperiodic CSI-RS for channel measurement, and correspondingly use periodic, semi-persistent, or aperiodic CSI-IM for interference measurement. Only aperiodic NZP CSI-RS can be used for interference measurement.
  • Each trigger state can be associated with 1, 2, or 3 resource settings.
  • resource setting used for beam management; Associated with 2 resource settings: one setting is used for channel measurement, and the other setting is used for interference measurement based on CSI-IM or interference measurement based on NZP CSI-RS; Associated with 3 resource settings: one setting is used for channel measurement, one setting is used for interference measurement based on CSI-IM, and the other setting is used for interference measurement based on NZP CSI-RS. If a resource setting contains multiple resource sets, only one resource set is selected. The QCL information of the CSI-RS resources in this resource set is configured by the TCI state for each resource.
  • the feedback slot offset for aperiodic CSI reporting is similar to that of SP-CSI.
  • the slot offset for AP-CSI is indicated by DCI, and its candidate values are configured in the report setting via RRC signaling. Since each trigger state can correspond to multiple report settings, different report settings may be configured with different reporting offsets. To ensure that all non-periodic CSI reports are reported within the same PUSCH resource, a unique reporting offset needs to be determined.
  • the maximum slot offset among the reporting offsets of each non-periodic CSI report indicated by DCI is defined as the slot offset corresponding to this trigger state.
  • a CSI report consists of two parts: Part 1 and Part 2.
  • Part 1 also called Part 1
  • Part 2 also called Part 2. If the current CSI measurement is used for CSI channel measurement, the reported content follows the following rules depending on the codebook type:
  • part 1 For Type I CSI, part 1 includes RI (Rank Indicator)/CRI (CSI-RS Resource Indicator) and the CQI (Channel Quality Indicator) of the first CW (codeword); part 2 includes LI (Layer Indicator) and PMI (Precoding Matrix Indicator), and when the rank is greater than 4, it also includes the CQI of the second CW.

  • Part I information can be reported in the following mapping order:
  • Hybrid beamforming can be understood as digital beamforming/digital precoding superimposed on analog beamforming.
  • different resources within the CSI-RS resource set can be transmitted through different analog beams, and the terminal device can then feed back its respective digital beam (precoding, PMI) based on the different resources transmitted by different analog beams.
  • PMI digital beam
  • the multi-port CSI reporting and codebook design do not specify the reporting field information or reporting priority definition within the CSI reporting field.
  • This application enhances/adds the CSI reporting field/reporting field information and reporting priority definition based on multi-port CSI reporting. This allows the base station to obtain the optimal codebook parameters and channel state information within a specified memory limit. Therefore, the base station can calculate the optimal precoding information matching the current channel, further improving transmission efficiency and quality.

发明人发现，在目前的5G传统网络中，CSI测量上报仅支持最多32端口的CSI-RS(信道状态信息参考信号)资源接收，测量以及CSI的上报。因此，目前的CSI测量上报机制并不能支持最多128端口的CSI测量上报，从而基站侧不能完全获取更多数量天线阵列的准确的信道状态信息。此外，针对现有的CSI测量上报框架的扩展也是十分具有挑战性的，尤其是随着天线端口的扩展而导致的成倍增强的CSI上报和反馈。因此，目前标准急需对现有标准方案进行一系列的增强。
针对上述问题至少之一或其他类似问题，本申请实施例提供一种信道状态信息的上报方法以及装置，以便终端设备能够高效且准确地进行CSI测量。
根据本申请实施例的一个方面，提供一种信道状态信息的上报方法，包括：
终端设备接收CSI-RS资源配置和/或与所述CSI-RS资源配置相关的CSI上报设置，所述CSI-RS资源配置包括至少一个CSI-RS资源集，每个CSI-RS资源集包括至 少K个CSI-RS资源，所述CSI上报设置包括码本设置和/或M个子上报信息；
所述终端设备根据所述CSI-RS资源配置和/或所述CSI上报设置上报所述M个子上报信息。
根据本申请实施例的另一方面，提供一种信道状态信息的上报装置，配置于终端设备，该装置包括：
接收单元，其接收CSI-RS资源配置和/或与所述CSI-RS资源配置相关的CSI上报设置，所述CSI-RS资源配置包括至少一个CSI-RS资源集，每个CSI-RS资源集包括至少K个CSI-RS资源，所述CSI上报设置包括码本设置和/或M个子上报信息；
发送单元，其根据所述CSI-RS资源配置和/或所述CSI上报设置上报所述M个子上报信息。
本申请实施例的有益效果之一在于：通过增强/新增基于多端口CSI上报的CSI上报域/上报域信息以及上报优先级定义，基站侧可在规定内存下获取最优码本参数以及信道状态信息，因此，基站可计算匹配当前信道的最优预编码信息，进一步提高传输效率以及传输质量。

在移动通信系统中，通常由终端设备根据网络设备的指示和配置进行CSI测量、再将测量得到的CSI上报给网络设备。网络设备在对该终端设备进行调度的时候，可以参考该CSI以便在合适的物理资源采用合适的传输方式调度该终端设备进行传输。不同的终端设备可能经历不同的物理信道条件，采用CSI反馈机制可以合理有效地利用物理资源，从而提高整个网络传输的效率。
NR的CSI反馈机制中，终端设备主要基于CSI配置对参考信号进行测量并上报测量结果，参考信号包括CSI-RS和SSB等。NR的CSI配置主要分为两部分，其一是网络设备为终端设备配置用于CSI测量的参考信号资源(CSI-RS资源配置)，其二是网络设备配置终端设备如何进行上报(CSI上报设置)。这两种配置原理较为简单，但协议中具体细节较为复杂。这里仅介绍与本申请相关的细节。
CSI-RS资源配置(resource setting)中，可以用于干扰测量和CSI信道测量等。每个resource setting包含S个资源集(resource set)。而每个resource set包含Ks个CSI-RS资源。非周期的resource setting可以包含一个或多个resource set。对于周期的和半持续的resource setting，用于CSI获取时，只能包含一个resource set。
此外，关于Ks的取值，当用于CSI信道测量时，若CSI上报设置中的码本类型为‘Type I’(具体可包括CodebookType＝’TypeISinglePanle’或’TypeIMultiPanle’)，Ks≤32；当用于CSI信道测量时，若CSI上报设置中的码本类型为‘Type II’(具体可包括CodebookType＝'typeII'，'typeII-PortSelection'，'typeII-r16'，'typeII-PortSelection-r16'，'typeII-PortSelection-r17')，Ks＝1。这主要是由于TypeII的计算复杂度相对较大，对终端设备的计算挑战性较大，因此NR系统通过限制Ks的取值来相对降低终端设备的计算复杂度。
在NR的CSI上报框架中，通过CSI报告(用于上报)关联CSI资源(用于测量)的方式来进行。CSI报告可以配置为以下三种类型：周期CSI报告(P-CSI)，仅在物理上行控制信道(Physical Uplink Control Channel，PUCCH)上传输；半持续CSI报告(SP-CSI)，在PUCCH或物理上行共享信道(Physical Uplink Shared Channel，PUSCH)上传输；非周期CSI报告(AP-CSI)，仅在PUSCH上传输。其中，周期CSI报告只能关联周期CSI-RS，半持续CSI报告可以关联周期和半持续CSI-RS，非周期CSI报告可以关联周期、半持续和非周期CSI-RS。
周期CSI报告(P-CSI)的反馈与LTE类似，其反馈周期和时隙偏移由RRC配置。周期性CSI报告只能采用周期性CSI-RS进行信道测量，采用周期性CSI-IM进行干扰测量，同时不支持使用NZP CSI-RS进行干扰测量。用于CSI获取时，每个周期CSI上报设置(CSI reporting setting或CSI reporting config)所关联的资源配置(resource setting)中仅包含一个CSI-RS资源集合。其中每个CSI-RS资源的QCL信息由此资源配置的TCI状态(TCI state)确定。
半持续CSI报告(SP-CSI)的反馈可以使用周期CSI-RS或者SP-CSI-RS进行信道测量，相应的使用周期CSI-IM或者SP-CSI-IM进行干扰测量，不支持NZP CSI-RS用于干扰测量。SP-CSI可以基于PUSCH上报也可以基于PUCCH上报。其中基于PUSCH上报的SP-CSI更类似于非周期CSI上报，其反馈资源为动态分配；而基于PUCCH上报的SP-CSI更类似周期CSI上报，其反馈资源半静态指示。因而这两种反馈采用不同的激活与去激活方式。
对于基于PUSCH上报的SP-CSI，可以由DCI信令激活和去激活。在CSI反馈框架下，RRC配置多个触发状态(trigger state)，最大64个触发状态，且每个触发状态对应一个CSI reporting setting。使用DCI中的CSI请求域激活一个触发状态。且同一时刻可以有多个处于激活状态的基于PUSCH的SP-CSI。用于CSI获取时，每个CSI reporting setting所关联的resource setting中仅包含一个CSI-RS resource set。
对于SP-CSI的激活与去激活，为了区别非周期CSI上报触发与SP-CSI上报激活，可以采用经过SP-CSI C-RNTI加扰的DCI格式0_1实现SP-CSI的激活与去激活。
对于SP-CSI的反馈时隙偏移，由于PUSCH资源为动态分配，因此SP-CSI的反馈时隙偏移由DCI指示，此反馈时隙偏移表示由DCI激活至SP-CSI上报的时隙数。当时隙n激活SP-CSI上报，且DCI指示时隙偏移为Y时，第一次SP-CSI上报时隙为n+Y，第二次SP-CSI上报时隙为n+Y+P，依次上报。其中P表示SP-CSI的反馈周期。此反馈时隙Y的候选值由RRC信令在CSI上报设置(CSI reporting setting)中配置。
对于BWP切换时的激活与去激活，由于PUSCH资源为动态分配，在上行或下行BWP切换时，基于PUSCH的CSI上报均被去激活。当BWP切换回来后，需要重新使用DCI信令激活。
对于基于PUCCH上报的SP-CSI，可以由MAC CE激活和去激活。在CSI反馈 框架下，RRC配置多个SP CSI report setting，且为每个report setting配置多个PUCCH资源，其中为每个候选UL BWP配置一个PUCCH资源。MAC CE一次只激活一个report setting。
对于SP-CSI的反馈时隙偏移，PUCCH资源为半静态分配，因此SP-CSI的反馈周期和时隙偏移由RRC在report setting中配置。其表示系统的绝对时隙位置，与MAC CE的激活时间无关。
对于BWP切换时的激活与去激活，当上行BWP切换时，由于每个候选BWP的PUCCH资源已经由RRC配置，因此可以保证连续的SP-CSI反馈。考虑到PUCCH资源的半静态分配，当下行BWP切换时，基于PUCCH的CSI上报保持激活状态，当BWP切换回来后，无需使用新的DCI信令激活，可以继续上报。
非周期CSI报告(AP-CSI)采用MAC CE结合DCI的方式进行配置和触发，并基于PUSCH上报。RRC配置多个CSI触发状态，与SP-CSI报告不同，每个CSI触发状态可以对应一个或者多个report setting。由DCI中的CSI请求域触发一个report setting。DCI格式0_1中的CSI请求域的大小可由RRC信令配置为0～6bits，因此最多可以指示64个CSI触发状态。当RRC配置的CSI触发状态超过64时，由MAC CE信令将其中的64个CSI触发状态映射至CSI请求域指示。非周期CSI上报可以采用周期、半持续或非周期CSI-RS进行信道测量，相应的使用周期、半持续或非周期CSI-IM进行干扰测量，同时只能采用非周期NZP CSI-RS进行干扰测量。每个触发状态可以关联至1、2、3个resource setting。
关联至1个resource setting：用于波束管理；关联至2个resource setting的情况下，一个setting用于信道测量，另一个setting用于基于CSI-IM的干扰测量或者基于NZP CSI-RS的干扰测量；关联至3个resource setting的情况下，一个setting用于信道测量，一个setting用于基于CSI-IM的干扰测量，另一个setting用于基于NZP CSI-RS的干扰测量，其中，若resource setting中包含多个resource set，则只选择其中一个resource set，此resource set中的CSI-RS资源的QCL信息由TCI state为每个资源配置。
非周期CSI报告(AP-CSI)的反馈时隙偏移类似于SP-CSI，非周期CSI报告的时隙偏移由DCI指示，且其候选取值由RRC信令在report setting中配置。由于每个触发状态可以对应多个report setting，不同的report setting可能配置为不同的上报偏 移，为了保证所有的非周期CSI报告在同一个PUSCH资源中上报，需要确定唯一的一个上报偏移。NR系统中定义使用DCI指示的每个非周期CSI报告的上报偏移中的最大时隙偏移作为此触发状态对应的时隙偏移。假设触发状态对应N个report setting，若Yi表示DCI指示的report setting i的上报偏移，则确定此触发状态的非周期CSI报告的上报偏移为Y＝maxiYi，i＝0,1,…,N-1。
一个CSI报告(report)由两部分组成，即第一部分Part1和第二部分Part2，其中，CSI报告的第一部分(CSIPart1，也可以称之为Part1)有一个固定的负载大小，并指示CSI的第二部分(CSIPart2，也可以称之为Part2)的信息比特(bit)的数量。CSI报告中，若当前CSI测量用于CSI信道测量，根据不同的码本类型，上报内容有以下的规定：
对于Type I CSI，part1包括RI(Rank Indicator，秩指示)/CRI(CSI-RS Resource Indicator，CSI-RS资源指示)及第一个CW(codeword，码字)的CQI(Channel Quality Indicator，信道质量指示)；part2包括LI(Layer Indicator，层指示)和PMI(Precoding Matrix Indicator，预编码矩阵指示)，且秩(rank)大于4时还包括第二个CW的CQI。
对于Type IICSI，part1包括RI、CQI和每层非零宽带幅度系数的个数；part2包括LI和PMI。
CSI报告可以通过PUCCH或PUSCH上报，该CSI报告可以分为下述两个部分，即part I和part II。
在上述CSI报告中，part I信息可以按照下列顺序进行映射顺序上报：
在上述CSI报告中，由于part II中的PMI信息开销比特过大，Part II内的PMI参数可全部分为以下三个组Group 0,1,2信息，并按时下列顺序进行优先级上报：
Group 0(G0)>Group 1(G1)>Group 2(G2)
在目前5G网络中，CSI测量上报仅支持最多32端口的CSI-RS资源接收，测量以及CSI信息的上报。因此，目前的CSI测量上报机制并不能支持最多128端口的CSI测量上报，从而基站侧不能完全获取更多数量天线阵列的准确的CSI信道状态信息。此外，随着更多天线端口的引入，数字端口/TXRU的数量并不能随之大量增加，这主要是由于硬件射频链路的复杂度以及高成本造成的。因此，混合波束赋形(Hybrid beamforming)在当前场景被引入增强。混合波束赋形可理解为数字波束赋形/数字预编码叠加模拟波束赋形。在混合波束赋形的增强下，如图1所示，CSI-RS资源集内的不同资源可以通过不同的模拟波束所发送，终端设备可基于不同模拟波束发送的不同资源再反馈各自的数字波束(预编码，PMI)。
然而，针对现有的CSI测量上报框架，终端设备无法基于多个模拟波束发送的资源上报多个CSI信息。因此，对现有的CSI测量上报框架的扩展也是十分具有挑战性的，尤其是随着天线端口的扩展而导致的成倍增强的CSI上报、反馈。因此，目前标准急需对现有标准方案进行一系列的增强。
此外，在多端口CSI上报和码本设计中，并没有规定CSI上报域中上报域信息以及上报优先级定义。本申请通过增强/新增基于多端口CSI上报的CSI上报域/上报域信息以及上报优先级定义，基站侧可在规定内存下获取最优码本参数以及信道状态信息，因此，基站可计算匹配当前信道的最优预编码信息，进一步提高传输效率以及传输质量。
下面结合附图对本申请实施例的各种实施方式进行说明。在以下的说明中，“当…时”、“如果…”以及“在…情况下”可以互换。此外，括号中的内容用于对括号前的内容进行解释或举例，本申请并不以括号中的内容作为限制。
第一方面的实施例
本申请实施例提供一种信道状态信息的上报方法，从终端设备的一侧进行说明。图2是本申请实施例的信道状态信息的上报方法的一示意图，如图2所示，该方法包括：
210：终端设备接收CSI-RS资源配置(resource setting)和/或与所述CSI-RS资源配置相关的CSI上报设置(report config)，上述CSI-RS资源配置包括至少一个 CSI-RS资源集，每个CSI-RS资源集包括至少K个CSI-RS资源，上述CSI上报设置包括码本设置和/或M个子上报信息；
220：终端设备根据上述CSI-RS资源配置和/或上述CSI上报设置上报上述M个子上报信息。
值得注意的是，以上附图2仅对本申请实施例进行了示意性说明，但本申请不限于此。例如可以增加其他的一些操作或者减少其中的某些操作。本领域的技术人员可以根据上述内容进行适当地变型，而不仅限于上述附图2的记载。
在上述实施例中，CSI-RS资源配置和/或CSI上报设置可以通过RRC信令发送，本申请对具体的实现方式不做限制。
根据上述实施例，当网络设备对天线配置进行调整的时候，对CSI-RS资源配置和/或CSI上报设置进行增强，能够使得终端设备高效、准确地进行CSI测量。
在一些实施例中，M个子上报信息在一个CSI上报信息中上报，每个子上报信息包括CSI part I上报域信息和/或CSI part II上报域信息。相应的，CSI上报信息包括CSI part I信息和/或CSI part II信息。下面对CSI part I信息和CSI part II信息的生成方式分别进行说明。
对于CSI上报信息中的CSI part I信息。
在一些实施例中，终端设备可以根据M个CSI part I上报域信息确定CSI part I上报的映射顺序和/或上报优先级，并根据确定的CSI part I上报的映射顺序和/或上报优先级生成CSI上报信息中的CSI part I信息。
在上述实施例中，每个CSI part I上报域信息可以包括以下至少之一：
CRI信息；
RI信息；
宽带CQI信息；
子带CQI信息；以及
非零系数个数信息。
在一些可能的实现方式中，终端设备根据下述M个CSI part I上报域信息确定CSI part I上报的映射顺序和/或上报优先级，也即，CSI part I的上报优先级按照从高到低的顺序依次为：
{第1个CRI信息，RI信息，宽带CQI信息，子带CQI信息，非零系数个数信 息}，{第i+1个CRI信息，RI信息，宽带CQI信息，子带CQI信息，非零系数个数信息}，…，{第M个CRI信息，RI信息，宽带CQI信息，子带CQI信息，非零系数个数信息}。
在另一些可能的实现方式中，终端设备根据下述M个CSI part I上报域信息确定CSI part I上报的映射顺序和/或上报优先级，也即，CSI part I的上报优先级按照从高到低的顺序依次为：
{第1个CRI信息，第i+1个CRI，…，第M个CRI信息}，{第1个RI信息，第i+1个RI，…，第M个RI信息}，{第1个宽带CQI信息，第i+1个宽带CQI信息，…，第M个宽带CQI信息}，{第1个子带CQI信息，第i+1个子带CQI信息，…，第M个子带CQI信息}，{第1个非零系数个数信息，第i+1个非零系数个数信息，…，第M个非零系数个数信息}。
在又一些可能的实现方式中，终端设备根据下述M个CSI part I上报域信息确定CSI part I上报的映射顺序和/或上报优先级，也即，CSI part I的上报优先级按照从高到低的顺序依次为：
{第1个CRI信息，第i+1个CRI，…，第M个CRI信息}，{第1个RI信息，第i+1个RI，…，第M个RI信息}，{第1个宽带CQI信息}，{第1个子带CQI信息}，{第1个非零系数个数信息，第i+1个非零系数个数信息，…，第M个非零系数个数信息}。
在又一些可能的实现方式中，终端设备根据下述M个CSI part I上报域信息确定CSI part I上报的映射顺序和/或上报优先级，也即，CSI part I的上报优先级按照从高到低的顺序依次为：
{第1个CRI信息，第i+1个CRI，…，第M个CRI信息}，{第1个RI信息，第i+1个RI，…，第M个RI信息}，{第1个非零系数个数信息，第i+1个非零系数个数信息，…，第M个非零系数个数信息}。
在上述实施例中，非零系数个数信息仅在码本设置为type II码本时存在，因此，在一些实施例中，当码本设置为type I码本时，终端设备无需在CSI part I上报域信息内上报上述非零系数个数信息。也即，上述M个CSI part I上报域信息不包含上述非零系数个数信息。
在一些实施例中，CSI上报设置还包括M个子上报信息中的M’个子上报信息， 该M’个子上报信息对应上述K个CSI-RS资源中的M’个CSI-RS资源；终端设备可以根据该M’个子上报信息的优先级生成CSI part I信息。
在上述实施例中，网络设备在CSI上报设置中为终端设备配置M’个子上报信息，以要求终端设备必须上报这M’个子上报信息。由此终端设备可以根据该M’个子上报信息的优先级生成CSI part I信息。
在上述实施例中，M’个子上报信息可以通过K比特的比特图进行配置，例如该比特图中包括M’个值为预定值(比如1)的比特，或者，M’个子上报信息也可以通过M’个CSI-RS资源的索引值信息进行配置。
在上述实施例中，M’个子上报信息的优先级高于上述M个子上报信息中其他子上报信息的优先级，也即，网络设备要求终端设备上报的这M’个子上报信息的优先级最高。
在一些实施例中，终端设备还可以根据M’个子上报信息中的CSI part I上报域信息(也即M’个CSI part I上报域信息)确定CSI part I上报的映射顺序和/或上报优先级，并根据确定的该CSI part I上报优先级生成CSI上报信息中的CSI part I信息。
例如，在一些可能的实现方式中，终端设备根据下述M’个子上报信息中的CSI part I上报域信息确定CSI part I上报的映射顺序和/或上报优先级：
{第1个CRI信息，RI信息，宽带CQI信息，子带CQI信息，非零系数个数信息}，{第i+1个CRI信息，RI信息，宽带CQI信息，子带CQI信息，非零系数个数信息}，…，{第M’个CRI信息，RI信息，宽带CQI信息，子带CQI信息，非零系数个数信息}。其中，i＝0,1,…M’。
再例如，在一些可能的实现方式中，终端设备根据下述M’个子上报信息中的CSI part I上报域信息确定CSI part I上报的映射顺序和/或上报优先级：
{第1个CRI信息，第i+1个CRI，…，第M’个CRI信息}，{第1个RI信息，第i+1个RI，…，第M’个RI信息}，{第1个宽带CQI信息，第i+1个宽带CQI信息，…，第M’个宽带CQI信息}，{第1个子带CQI信息，第i+1个子带CQI信息，…，第M’个子带CQI信息}，{第1个非零系数个数信息，第i+1个非零系数个数信息，…，第M’个非零系数个数信息}。其中，i＝0,1,…M’。
在前述各个实施例中，终端设备生成CSI part I信息还包括：终端设备略去(omit)或丢弃(drop)上述M个子上报信息或者上述M’个子上报信息中的部分信息。例如， 终端设备按照CSI part I上报的映射顺序确定CSI part I上报优先级，并按照确定的CSI part I上报优先级略去(omit)上述M个子上报信息或者上述M’个子上报信息中的优先级低的CSI part I信息，直至当前CSI part I信息的相关码率小于或等于网络侧配置的码率。
例如，当当前CSI part I信息的相关码率太高时，终端设备可以先丢弃上述M个CSI part I上报域信息中的{第M个CRI信息，RI信息，宽带CQI信息，子带CQI信息，非零系数个数信息}，如果仍不能满足要求，继续丢弃上述M个CSI part I上报域信息中的{第M-1个CRI信息，RI信息，宽带CQI信息，子带CQI信息，非零系数个数信息}，以此类推。
再例如，当当前CSI part I信息的相关码率太高时，终端设备可以先丢弃上述M个CSI part I上报域信息中的{第1个非零系数个数信息，第i+1个非零系数个数信息，…，第M个非零系数个数信息}，如果仍不能满足要求，继续丢弃上述M个CSI part I上报域信息中的{第1个子带CQI信息，第i+1个子带CQI信息，…，第M个子带CQI信息}，以此类推。
再例如，当当前CSI part I信息的相关码率太高时，终端设备可以先丢弃上述M’个CSI part I上报域信息中的{第M’个CRI信息，RI信息，宽带CQI信息，子带CQI信息，非零系数个数信息}，如果仍不能满足要求，继续丢弃上述M’个CSI part I上报域信息中的{第M’-1个CRI信息，RI信息，宽带CQI信息，子带CQI信息，非零系数个数信息}，以此类推。
再例如，当当前CSI part I信息的相关码率太高时，终端设备可以先丢弃上述M’个CSI part I上报域信息中的{第1个非零系数个数信息，第i+1个非零系数个数信息，…，第M’个非零系数个数信息}，如果仍不能满足要求，继续丢弃上述M’个CSI part I上报域信息中的{第1个子带CQI信息，第i+1个子带CQI信息，…，第M’个子带CQI信息}，以此类推。
对于CSI上报信息中的CSI part II信息。
在一些实施例中，终端设备可以根据M个CSI part II上报域信息确定CSI part II上报的映射顺序和/或上报优先级，并根据确定的CSI part II上报的映射顺序和/或上报优先级生成CSI上报信息中的CSI part II信息。
在上述实施例中，每个CSI part II上报域信息可以包括PMI信息，该PMI信息 包括宽带PMI信息和/或子带PMI信息。
在一些可能的实现方式中，当码本设置为type I码本且上述M个CSI part II上报域信息为宽带PMI信息时，终端设备可以根据下述M个CSI part II上报域信息确定CSI part II上报的映射顺序和/或上报优先级，也即，CSI part II的上报优先级按照从高到低的顺序依次为：
{第1个CRI对应的PMI信息，第i+1个CRI对应的PMI信息，…，第M个CRI对应的PMI信息}；或者，
{第1个CRI对应的PMI信息}，{第i+1个CRI对应的PMI信息}，…，{第M个CRI对应的PMI信息}。
在上述实现方式，在由于码率过高需要进行略去(omit)或丢弃(drop)时，可以先从优先级低的信息开始略去(omit)或丢弃(drop)，例如对于上述第二种排序，先略去{第M个CRI对应的PMI信息}，如果码率仍不能满足要求，继续略去{第M-1个CRI对应的PMI信息}，以此类推。
在另一些可能的实现方式中，当码本设置为type I码本且上述M个CSI part II上报域信息为子带PMI信息时，终端设备可以根据下述M个CSI part II上报域信息确定CSI part II上报的映射顺序和/或上报优先级，也即，CSI part II的上报优先级按照从高到低的顺序依次为：
{第1个CRI对应的偶数子带PMI信息}，{第i+1个CRI对应的偶数子带PMI信息}，…，{第M个CRI对应的偶数子带PMI信息}，{第1个CRI对应的奇数子带PMI信息}，第i+1个CRI对应的奇数子带PMI信息}，…，{第M个CRI对应的奇数子带PMI信息}；或者，
{第1个CRI对应的偶数子带PMI信息}，{第1个CRI对应的奇数子带PMI信息}，{第i+1个CRI对应的偶数子带PMI信息}，{第i+1个CRI对应的奇数子带PMI信息}，…，{第M个CRI对应的偶数子带PMI信息}，{第M个CRI对应的奇数子带PMI信息}；或者，
{第1个CRI对应的偶数子带PMI信息，第1个CRI对应的奇数子带PMI信息}，{第i+1个CRI对应的偶数子带PMI信息，第i+1个CRI对应的奇数子带PMI信息}，…，{第M个CRI对应的偶数子带PMI信息，第M个CRI对应的奇数子带PMI信息}。
在上述实现方式，在由于码率过高需要进行略去(omit)或丢弃(drop)时，可 以先从优先级低的信息开始略去(omit)或丢弃(drop)，例如对于上述第一种排序，先略去{第M个CRI对应的奇数子带PMI信息}，如果码率仍不能满足要求，继续略去{第M-1个CRI对应的奇数子带PMI信息}；再例如对于上述第二种排序，先略去{第M个CRI对应的奇数子带PMI信息}，如果码率仍不能满足要求继续略去{第M个CRI对应的偶数子带PMI信息}；再例如对于上述第三种排序，先略去{第M个CRI对应的偶数子带PMI信息，第M个CRI对应的奇数子带PMI信息}，如果码率仍不能满足要求继续略去{第M-1个CRI对应的偶数子带PMI信息，第M-1个CRI对应的奇数子带PMI信息}，以此类推。
在又一些可能的实现方式中，当码本设置为type II码本时，终端设备可以根据下述M个CSI part II上报域信息确定CSI part II上报的映射顺序和/或上报优先级，也即，CSI part II的上报优先级按照从高到低的顺序依次为：
{第1个CRI对应的group 0信息，第i+1个CRI对应的group 0信息，…，第M个CRI对应的group 0信息}，{第1个CRI对应的group 1信息}，{第i+1个CRI对应的group 1信息}，…，{第M个CRI对应的group 1信息}，{第1个CRI对应的group 2信息}，{第i+1个CRI对应的group 2信息}，…，{第M个CRI对应的group 2信息}；或者，
{第1个CRI对应的group 0信息，第i+1个CRI对应的group 0信息，…，第M个CRI对应的group 0信息}，{第1个CRI对应的group 1信息}，{第1个CRI对应的group 2信息}，{第2个CRI对应的group 1信息}，第2个CRI对应的group 2信息}，…，{第M个CRI对应的group 1信息}，{第M个CRI对应的group 2信息}；或者，
{第1个CRI对应的group 0信息，第i+1个CRI对应的group 0信息，…，第M个CRI对应的group 0信息}，{第1个CRI对应的group 1信息，第1个CRI对应的group 2信息}，{第2个CRI对应的group 1信息，第2个CRI对应的group 2信息}，…，{第M个CRI对应的group 1信息，第M个CRI对应的group 2信息}；或者，
{第1个CRI对应的group 0信息，第1个CRI对应的group 1信息，第1个CRI对应的group 2信息}，{第2个CRI对应的group 0信息，第2个CRI对应的group 1信息，第2个CRI对应的group 2信息}，…，{第M个CRI对应的group 0信息，第M个CRI对应的group 1信息，第M个CRI对应的group 2信息}；或者，
{第1个CRI对应的group 0信息}，{第1个CRI对应的group 1信息}，第1个CRI对应的group 2信息}，{第2个CRI对应的group 0信息}，{第2个CRI对应的group 1信息}，{第2个CRI对应的group 2信息}，…，{第M个CRI对应的group 0信息}，{第M个CRI对应的group 1信息}，{第M个CRI对应的group 2信息}。
在上述实现方式，在由于码率过高需要进行略去(omit)或丢弃(drop)时，可以先从优先级低的信息开始略去(omit)或丢弃(drop)，例如对于上述第一种排序，先略去{第M个CRI对应的group 2信息}，如果码率仍不能满足要求，继续略去{第M-1个CRI对应的group 2信息}；再例如对于上述第二种排序，先略去{第M个CRI对应的group 2信息}，如果码率仍不能满足要求继续略去{第M个CRI对应的group 1信息}；再例如对于上述第三种排序，先略去{第M个CRI对应的group 1信息，第M个CRI对应的group 2信息}，如果码率仍不能满足要求继续略去{第M-1个CRI对应的group 1信息，第M-1个CRI对应的group 2信息}；再例如对于上述第四种排序，先略去{第M个CRI对应的group 0信息，第M个CRI对应的group 1信息，第M个CRI对应的group 2信息}，如果码率仍不能满足要求继续略去{第M-1个CRI对应的group 0信息，第M-1个CRI对应的group 1信息，第M-1个CRI对应的group 2信息}；再例如对于上述第五种排序，先略去{第M个CRI对应的group 2信息}，如果码率仍不能满足要求继续略去{第M个CRI对应的group 1信息}，以此类推。此外，针对{第1个CRI对应的group 0信息，第i+1个CRI对应的group 0信息，…，第M个CRI对应的group 0信息}为相同优先级，则需全部保留或略去。
在一些实施例中，CSI上报设置还包括M个子上报信息中的M’个子上报信息，该M’个子上报信息对应上述K个CSI-RS资源中的M’个CSI-RS资源；终端设备可以根据该M’个子上报信息的优先级生成CSI part II信息。
在上述实施例中，网络设备在CSI上报设置中为终端设备配置M’个子上报信息，以要求终端设备必须上报这M’个子上报信息。由此终端设备可以根据该M’个子上报信息的优先级生成CSI part II信息。
在上述实施例中，M’个子上报信息可以通过K比特的比特图进行配置，例如该比特图中包括M’个值为预定值(比如1)的比特，或者，M’个子上报信息也可以通过M’个CSI-RS资源的索引值信息进行配置。
在上述实施例中，M’个子上报信息的优先级高于上述M个子上报信息中其他子 上报信息的优先级，也即，网络设备要求终端设备上报的这M’个子上报信息的优先级最高。
在一些实施例中，上述M个CSI part II上报域信息至少还包括下述CQI信息中的其中之一：
M个子上报信息中的第一个码字和第二个码字的CQI信息；
M个子上报信息中的第二个码字的CQI信息；
M-M’个子上报信息中的第一个码字的CQI信息以及M个子上报信息中的第二个码字的CQI信息；
M-M’个子上报信息中的第一个码字的CQI信息以及第二个码字的CQI信息；
M’个子上报信息中的第一个码字的CQI信息以及M-M’个子上报信息中的第一个码字的CQI信息以及第二个码字的CQI信息；
其中，每个CQI信息包括宽带CQI信息以及子带CQI信息。
在一些实施例中，上述M个CSI part II上报域信息至少还包括M-M’个子上报信息中的CRI信息和/或RI信息。
在上述实施例中，在一些可能的实现方式中，CRI信息优先级高于RI信息的优先级，RI信息的优先级高于所述CQI信息的优先级，CQI信息的优先级高于PMI信息的优先级；其中，在一些可能的实现方式中，在M个CQI信息中，第一个码字的CQI信息的优先级高于第二个码字的CQI信息的优先级。
在前述各个实施例中，终端设备生成CSI part II信息还包括：终端设备略去(omit)或丢弃(drop)上述M个子上报信息中的部分信息。例如，终端设备按照CSI part II上报的映射顺序和/或上报优先级略去(omit)上述M个子上报信息中的优先级低的CSI part II上报域信息，直至当前CSI part II上报域信息的相关码率小于或等于网络侧配置的码率。
例如，当当前CSI part II信息的相关码率太高时，终端设备可以按照优先级从高到低的顺序先丢弃上述M个CSI part II上报域信息中优先级低的信息(也即排序靠后的信息)，如果仍不能满足要求，继续丢弃上述M个CSI part II上报域信息中优先级次低的信息，以此类推。
在前述实施例中，对终端设备根据CSI part I上报域信息确定CSI part I上报优先级并生成CSI part I上报信息以及根据CSI part II上报域信息确定CSI part II上报优先 级并生成CSI part II上报信息做了说明。在一些实施例中，终端设备也可以不区分上报域，而是根据预定义的公式确定CSI上报优先级，进而生成CSI上报信息。
例如，终端设备根据下面的公式(称为第一公式)确定CSI上报优先级，并根据确定的CSI上报优先级生成上述CSI上报信息。
PriiCSI(y,k,c,s)＝2·Ncells·Ms·y*M+Ncells·Ms·k*M+Ms·c+s*M+i
在上述公式中，y代表CSI上报类型；k代表CSI上报是否携带信道质量信息；c代表服务小区索引；Ncells代表第一高层参数的值；s代表上报配置标识；Ms代表第二高层参数的值；M代表子上报信息的数量；i代表M个子上报信息中子上报信息(例如CRI)的索引，i＝0,1,…M。关于上述公式中各参数的含义，可以参考相关技术，此处不再赘述。
根据上述公式确定CSI上报优先级，上报的粒度缩小至了子上报信息，可以以子上报信息为力度进行CSI上报，同样的，可以以子上报信息为力度进行忽略(omit)。由此，终端设备可以高效且准确地进行CSI测量和上报，提高了传输效率和传输质量。并且，该方案对现有标准影响较小，优先级定义也较为清楚。
在一些实施例中，终端设备还可以根据CPU定义值更新CSI上报。例如，当全部子上报信息所占用的CPU资源大于CPU门限值时，终端设备只更新部分CSI上报。
在实际CSI传输中，终端侧会接收预定义的每种CSI类型下的CPU占用资源的定义值，使得终端侧进行CSI上报更新。当全部子上报信息所占用的CPU资源大于CPU门限值时，终端设备只更新其中部分CSI上报。
在上述实施例中，该CPU定义值与CSI-RS资源数K相关。
例如，该CPU定义值等于CSI-RS资源数K。
再例如，该CPU定义值等于CSI-RS资源数K与第一因子X的乘积。例如，X＝1，1.5，2。X的具体取值取决于终端设备能力的上报，本申请不限于此，X的具体取值也可以取决于网络侧的高层信令配置，等等。
再例如，该CPU定义值等于CSI-RS资源数K的Y次方。例如，Y＝2，2.5，3。Y的具体取值取决于终端设备能力的上报，本申请不限于此，Y的具体取值也可以取决于网络侧的高层信令配置。
再例如，该CPU定义值等于CSI-RS资源数K与Z的商。例如，Y＝2，2.5，3。Z的具体取值取决于终端设备能力的上报，本申请不限于此，Z的具体取值也可以取 决于网络侧的高层信令配置。
以上仅对X、Y以及Z的取值做了示意性说明，如前所述，其取值可以是预定义的，也可以是由终端设备确定的，还可以是网络设备配置的，本申请对此不做限制。
为了使本申请实施例的方法更加清楚易懂，下面通过具体的示例对本申请实施例的方法进行说明。
图3是本申请实施例的信道状态信息上报方法的另一示意图，示出了进行CSI part I上报域信息的上报的情况，其中与前面的实施例相同的内容不再重复说明。如图3所示，该方法包括：
310：终端设备接收CSI-RS资源配置和CSI上报设置；
320：终端设备计算CSI part I信息；
330：终端设备进行M个子上报信息的CSI part I上报域信息的上报；
340：终端设备忽略上报部分CSI part I上报域信息或者不进行忽略上报。
值得注意的是，以上附图3仅对本申请实施例进行了示意性说明，但本申请不限于此。例如可以增加其他的一些操作或者减少其中的某些操作。本领域的技术人员可以根据上述内容进行适当地变型，而不仅限于上述附图3的记载。例如，上述操作310可以分开执行，再例如，上述操作330和340可以合并执行，再例如，上述操作320～340可以合并执行，等等。
在操作310中，终端设备接收CSI-RS资源配置，该CSI-RS资源配置包括一个CSI-RS资源集用于信道测量，每个资源集包括K＝8个CSI-RS资源。
具体的，可在高层信令例如RRC信令中的NZP CSI-RS resource set内配置8个CSI-RS#x，其中，x为第k个CSI-RS资源的索引值，i为大于或等于1整数，k为大于1并且小于K＝8的整数。这8个CSI-RS#x例如为CSI-RS#1,CSI-RS#3,CSI-RS#4,CSI-RS#5,CSI-RS#7,CSI-RS#8,CSI-RS#9,CSI-RS#11。
在操作310中，终端设备接收CSI上报设置，该CSI上报设置包括码本设置和/或M＝2个子上报信息。
上述码本设置例如可以包括但不限于以下至少之一：‘r19-TypeI’，‘r19-TypeII’，‘r19-TypeIIDoppler’，‘r19-TypeIIPS’。
上述子上报信息的数量M的具体取值例如可以通过RRC信令来配置。可选的，当码本被配置为‘r19-TypeI’时，M可以为大于或等于1并且小于等于4的整数。 可选的，当码本被配置为‘r19-TypeII’，‘r19-TypeIIDoppler’，‘r19-TypeIIPS’时，M可以为大于或等于1并且小于或等于2的整数。
在一些示例中，上述CSI上报设置可选的还可以包括M’个子上报信息，M’小于M。
具体的，该M’个子上报信息例如可以通过配置该CSI上报设置中关联的CSI-RS资源集内的M’个CSI-RS的资源进行配置。
例如，可以通过K＝8比特的比特图(bitmap)进行配置，该比特图中包括M’＝1个取值为1的比特位，例如比特图‘01000000’表示CSI-RS资源集中的第2个CSI-RS资源。
再例如，还可通过M’＝1个CSI-RS资源的索引值信息进行配置，其中，M’＝1个CSI-RS资源是CSI-RS资源集内的。例如，可直接配置CSI-RS资源集内的CSI-RS#3，则表示CSI-RS资源集中的第2个CSI-RS资源为必选资源。
在上述示例中，当终端设备接收了M’个子上报信息后，CSI上报域信息中包括与M’个CSI-RS资源关联的CSI上报信息。具体的，该M’个子上报信息中可以包括CRI信息，也可以不包括CRI信息。
在操作320中，终端设备可以根据上述CSI-RS资源配置和CSI上报设置计算并上报CSI part I信息。
在一些示例中，终端设备通过测量大尺度RSRP等信道信息选择K个CSI-RS资源中的M个CSI-RS资源，并上报CRI_i信息。其中i＝0,1,..M-1，即i＝0,1。例如选择第一个CSI-RS资源和第二个CSI-RS资源，即CSI-RS#1和CSI-RS#3。
此外，终端设备可以上报M＝2个CRI信息，每个CRI信息的上报比特宽度均为上取整{log(K)}＝3bits；
或者，终端设备可以上报M-M’个CRI信息，每个CRI信息的上报比特宽度均为上取整{log(K-M’)}＝3bits，这是由于M’＝1个CSI-RS资源是网络设备要求终端设备必须上报的，因此无需额外上报CRI信息。
在另一些示例中，终端设备接收并测量上述选择的2个CSI-RS资源，并上报基于每个CSI-RS资源的RI_i＝2以及CQI_i信息，其中i＝0,1,..M-1，即i＝0,1。
其中，CQI信息可以包括宽带CQI信息和子带CQI信息。
此外，当码本设置为‘r19-TypeII’，‘r19-TypeIIDoppler’，‘r19-TypeIIPS’时， 终端设备还可以基于每个CSI-RS资源并推荐上报所有层的非零系数个数KNZ,i指示，其中i＝0,1,..M-1，即i＝0,1。
在操作330中，当终端设备仅接收到M个子上报信息的配置没收到M’个子上报信息的配置时，其可以基于以下两种映射优先级之一进行M＝2个子上报信息的CSI part I上报域信息的上报。
映射优先级顺序1：
{第1个CRI信息}>{第1个RI信息}>{第1个宽带CQI信息}>{第1个子带CQI信息}>{第1个非零系数个数信息(optional)}>{第2个CRI信息}>{第2个RI信息}>{第2个宽带CQI信息}>{第2个子带CQI信息}>{第2个非零系数个数信息(optional)}>…>{第i+1个CRI信息}>{第i+1个RI信息}>{第i+1个宽带CQI信息}>{第i+1个子带CQI信息}>{第i+1个非零系数个数信息(optional)}>…>{第M个CRI信息}>{第M个RI信息}>{第M个宽带CQI信息}>{第M个子带CQI信息}>{第M个非零系数个数信息(optional)。
以M＝2为例，i＝0,1,..M-1，即i＝0,1，则映射优先级顺序1为：

或者，映射优先级顺序1也可以是：
{第1个CRI信息>第1个RI信息>第1个宽带CQI信息>第1个子带CQI信息>第1个非零系数个数信息(optional)}>{第2个CRI信息>第2个RI信息>第2个宽带CQI信息>第2个子带CQI信息>第2个非零系数个数信息(optional)}>…>{第i+1个CRI信息>第i+1个RI信息>第i+1个宽带CQI信息>第i+1个子带CQI信息>第i+1个非零系数个数信息(optional)}>…>{第M‘个CRI信息>第M’个RI信息>第M‘个宽带CQI信息>第M’个子带CQI信息>第M‘个非零系数个数信息(optional)}。
在上述示例中，M个CRI可按照CSI-RS资源的索引值进行排序，即索引值低的CSI-RS资源的优先级高于索引值高的CSI-RS资源的优先级。
在上述示例中，M个CRI也可按照CSI-RS资源对应的信道质量进行排序，即CSI-RS测量的信道质量高的优先级高于CSI-RS测量的信道质量低的优先级；或CSI-RS测量的CQI高的优先级高于CSI-RS测量的CQI低的优先级。
在上述示例中，第i+1个RI，宽带CQI，子带CQI，非零系数个数可理解为第i+1个CRI对应的RI，宽带CQI，子带CQI，非零系数个数。
映射优先级顺序2：
{第1个CRI信息}>…>{第i+1个CRI信息}>…>{第M个CRI信息}>{第1个RI信息}>…>{第i+1个RI信息}>…>{第M个RI信息}>{第1个宽带CQI信息}>{第1个子带CQI信息}>…>{第i+1个宽带CQI信息}>{第i+1个子带CQI信息}>…>{第M个宽带CQI信息}>{第M个子带CQI信息}>{第1个非零系数个数信息(optional)}>…>{第i+1个非零系数个数信息(optional)}>…>{第M个非零系数个数信息(optional)}。
以M＝2为例，i＝0,1,..M-1，即i＝0,1，则映射优先级顺序2为：
{第1个CRI信息}>{第2个CRI信息}>{第1个RI信息}>{第2个RI信息}>{第1个宽带CQI信息}>{第1个子带CQI信息}>{第2个宽带CQI信息}>{第2个子带CQI信息}>{第1个非零系数个数信息(optional)}>{第2个非零系数个数信息(optional)}。
在操作330中，当终端设备接收到M个子上报信息的配置和M’个子上报信息的配置时，终端设备可以基于下述两种映射优先级之一进行M＝2个子上报信息的CSI part I上报域信息的上报：
映射优先级顺序1：
{第1个CRI信息}>{第1个RI信息}>{第1个宽带CQI信息}>{第1个子带CQI信息}>{第1个非零系数个数信息(optional)}>{第2个CRI信息}>{第2个RI信息}>{第2个宽带CQI信息}>{第2个子带CQI信息}>{第2个非零系数个数信息(optional)}>…>{第i+1个CRI信息}>{第i+1个RI信息}>{第i+1个宽带CQI信息}>{第i+1个子带CQI信息}>{第i+1个非零系数个数信息(optional)}>…>{第M个CRI信息}>{第M个RI信息}>{第M个宽带CQI信息}>{第M个子带CQI信息}>{第M个非零系数个数信息(optional)}。
以M＝2为例，i＝0,1,..M-1，即i＝0,1，则映射优先级顺序1为：
{第1个CRI信息}>{第1个RI信息}>{第1个宽带CQI信息}>{第1个子带CQI信息}>{第1个非零系数个数信息(optional)}>{第2个CRI信息}>{第2个RI信息}>{第2个宽带CQI信息}>{第2个子带CQI信息}>{第1个非零系数个数信息(optional)}。
在上述示例中，M个CRI可按照CSI-RS资源的索引值进行排序，即索引值低的CSI-RS资源的优先级高于索引值高的CSI-RS资源的优先级，其中，M’个CSI-RS资源对应的CRI可以不进行上报。具体的，映射顺序和/或优先级中前M’个CRI可以不报。
在上述示例中，M个CRI也可按照CSI-RS资源对应的信道质量进行排序，即CSI-RS测量的信道质量高的优先级高于CSI-RS测量的信道质量低的优先级；或CSI-RS测量的CQI高的优先级高于CSI-RS测量的CQI低的优先级，其中，M’个CSI-RS资源对应的CRI可以必须上报。
在上述示例中，由于M’＝1为必须上报CSI-RS资源，即网络侧配置CSI-RS#3资源为必须上报的资源。则M’个CSI-RS资源的CSI信息的优先级大于M-M’(M中除M’的剩余资源)的CSI信息的优先级。
其中，M’个CRI信息中，可按照CSI-RS资源的索引值进行排序，即索引值低的CSI-RS资源的优先级高于索引值高的CSI-RS资源的优先级，其中，M’个CSI-RS资源对应的CRI可以不报。具体的，映射顺序和/或优先级中前M’个CSI-RS资源 对应的CRI可以不报。
此外，M’个CRI信息中，可按照CSI-RS资源对应的信道质量进行排序，即CSI-RS测量的信道质量高的优先级高于CSI-RS测量的信道质量低的优先级；或CSI-RS测量的CQI高的优先级高于CSI-RS测量的CQI低的优先级，其中，M’个CSI-RS资源对应的CRI可以必须上报。
另外，M-M’个CRI信息中，可按照CSI-RS资源的索引值进行排序，即索引值低的CSI-RS资源的优先级高于索引值高的CSI-RS资源的优先级。
另外，M-M’个CRI信息中，可按照CSI-RS对应的信道质量进行排序，即CSI-RS测量的信道质量高的优先级高于CSI-RS测量的信道质量低的优先级；或CSI-RS测量的CQI高的优先级高于CSI-RS测量的CQI低的优先级。
在上述示例中，第i+1个RI，宽带CQI，子带CQI，非零系数个数可理解为第i+1个CRI对应的RI，宽带CQI，子带CQI，非零系数个数。
映射优先级顺序2：
{第1个CRI信息}>…>{第i+1个CRI信息}>…>{第M个CRI信息}>{第1个RI信息}>…>{第i+1个RI信息}>…>{第M个RI信息}>{第1个宽带CQI信息}>{第1个子带CQI信息}>…>{第i+1个宽带CQI信息}>{第i+1个子带CQI信息}>…>{第M个宽带CQI信息}>{第M个子带CQI信息}>{第1个非零系数个数信息(optional)}>…>{第i+1个非零系数个数信息(optional)}>…>{第M个非零系数个数信息(optional)}。
以M＝2为例，i＝0,1,..M-1，即i＝0,1，则映射优先级顺序2为：
{第1个CRI信息}>{第2个CRI信息}>{第1个RI信息}>{第2个RI信息}>{第1个宽带CQI信息}>{第1个子带CQI信息}>{第2个宽带CQI信息}>{第2个子带CQI信息}>{第1个非零系数个数信息(optional)}>{第2个非零系数个数信息(optional)}。
在上述示例中，M个CRI可按照CSI-RS资源的索引值进行排序，即索引值低的CSI-RS资源的优先级高于索引值高的CSI-RS资源的优先级，其中，M’个CSI-RS资源对应的CRI可以不进行上报。具体的，映射顺序和/或优先级中前M’个CRI可以不报。
在上述示例中，M个CRI也可按照CSI-RS资源对应的信道质量进行排序，即 CSI-RS测量的信道质量高的优先级高于CSI-RS测量的信道质量低的优先级；或CSI-RS测量的CQI高的优先级高于CSI-RS测量的CQI低的优先级，其中，M’个CSI-RS资源对应的CRI必须上报。
在上述示例中，由于M’＝1为必须上报CSI-RS资源，即网络侧配置CSI-RS#3资源为必须上报的资源。则M’个CSI-RS资源的CSI信息的优先级大于M-M’(M中除M’的剩余资源)的CSI信息的优先级。
其中，M’个CRI信息中，可按照CSI-RS资源的索引值进行排序，即索引值低的CSI-RS资源的优先级高于索引值高的CSI-RS资源的优先级，其中，M’个CSI-RS资源的对应的CRI可以不报。具体的，映射顺序和/或优先级中前M’个CRI可以不报。
此外，M’个CRI信息中，可按照CSI-RS资源对应的信道质量进行排序，即CSI-RS测量的信道质量高的优先级高于CSI-RS测量的信道质量低的优先级；或CSI-RS测量的CQI高的优先级高于CSI-RS测量的CQI低的优先级，其中，M’个CSI-RS资源对应的CRI必须上报。
另外，M-M’个CRI信息中，可按照CSI-RS资源的索引值进行排序，即索引值低的CSI-RS资源的优先级高于索引值高的CSI-RS资源的优先级。
另外，M-M’个CRI信息中，可按照CSI-RS对应的信道质量进行排序，即CSI-RS测量的信道质量高的优先级高于CSI-RS测量的信道质量低的优先级；或CSI-RS测量的CQI高的优先级高于CSI-RS测量的CQI低的优先级。
在操作340中，终端设备可以基于优先级顺序最低的优先级忽略上报部分CSI part I上报域信息，直到CSI报告码率小于或等于高层配置的最大码率；或者，终端测也可以基于优先级顺序映射全部上报CSI part I上报域信息，不进行忽略上报。
