W为计算的预编码用于下行数据传输；W is the calculated precoding used for downlink data transmission;

W₁由多个SD basis组成，或者为单位矩阵，其中单位矩阵中的1表示终端选择的端口；W ₁ is composed of multiple SD basis, or is the identity matrix, where 1 in the identity matrix represents the port selected by the terminal;

表示SD basis、FD basis和/或DD basis对应的组合系数； Indicates the combination coefficient corresponding to SD basis, FD basis and/or DD basis;

W_f由一个或多个FD basis组成；W _f consists of one or more FD basis;

在一些实施例中，基于Rel-15/16 Type II或Rel-18 Type II码本的每次CSI上报，CSI上报的内容包括SD/FD/DD basis、这些basis的组合系数等指示信息。基于Rel-17端口选择TypeII码本的每次上报，CSI上报的内容包括端口选择、端口组合系数等指示信息在配置的一次CSI上报中上报，其中，端口组合系数指示信息包括非零组合系数的位置指示信息和非零系数的幅度和相位量化信息。In some embodiments, for each CSI report based on Rel-15/16 Type II or Rel-18 Type II codebook, the content of the CSI report includes indication information such as SD/FD/DD basis and combination coefficients of these basis. For each report based on Rel-17 port selection Type II codebook, the content of the CSI report includes indication information such as port selection and port combination coefficient in a configured CSI report, wherein: The port combination coefficient indication information includes position indication information of non-zero combination coefficients and amplitude and phase quantization information of the non-zero coefficients.

但是，在大规模(Massive)多输入多输出(Multiple Input Multiple Output，MIMO)系统中，SD/FD/DD basis或端口选择在一定的时间范围内并不发生改变，它具有慢变特性，因此它可以不需要在每次CSI上报中都包含SD/FD/DD basis或端口选择的指示信息。然而，组合系数具有快变特性，在每次CSI上报中需包含组合系数的指示信息。However, in a massive multiple input multiple output (MIMO) system, the SD/FD/DD basis or port selection does not change within a certain time range, and it has a slow-changing characteristic, so it is not necessary to include the SD/FD/DD basis or port selection indication information in each CSI report. However, the combination coefficient has a fast-changing characteristic, and the combination coefficient indication information needs to be included in each CSI report.

由此可知，如果能够将SD/FD/DD basis的指示信息和组合系数指示信息分别独立上报，能够有效减少上报的开销。因此，如何对SD/FD/DD basis的指示信息和组合系数指示信息独立上报，是亟待解决的问题。It can be seen that if the indication information of the SD/FD/DD basis and the indication information of the combination coefficient can be reported independently, the reporting overhead can be effectively reduced. Therefore, how to report the indication information of the SD/FD/DD basis and the indication information of the combination coefficient independently is an issue to be solved urgently.

基于码本的CSI上报内容包括SD/FD/DD basis、RI、CQI指示和组合系数的指示量化上报。下面给出了SD/FD/DD basis与RI、CQI指示和组合系数的指示量化中的一种或多种独立上报方法：The codebook-based CSI reporting content includes SD/FD/DD basis, RI, CQI indication and quantized reporting of combination coefficients. One or more independent reporting methods of SD/FD/DD basis and RI, CQI indication and combination coefficient indication quantization are given:

对于配置多个不同非周期或半持续CSI上报配置，网络侧可通过发送一个或多个相同的信令如DCI和/或MAC-CE触发上报。For configuring multiple different non-periodic or semi-persistent CSI reporting configurations, the network side may trigger reporting by sending one or more identical signalings such as DCI and/or MAC-CE.

·上述上报的指示信息中至少SD/FD/DD basis的指示上报与组合系数的指示量化信息通过两个不同的CSI上报需要通过以下一种方式或多种方式相关联：At least the SD/FD/DD basis indication report and the combination coefficient indication quantization information in the above-mentioned indication information need to be associated through two different CSI reports in one or more of the following ways:

方式1、这两个不同的CSI上报关联同一个信道测量资源。Mode 1: These two different CSI reports are associated with the same channel measurement resource.

方式2、组合系数的指示量化信息上报关联一个与此组合系数的指示量化信息上报最近的一次SD/FD/DD basis指示上报。Method 2: The quantitative information report of the combination coefficient is associated with a nearest quantitative information report of the combination coefficient. The secondary SD/FD/DD basis indication is reported.

方式4、通过分配相同的上行资源相关联，如分配相同的PUCCH或PUSCH资源。Mode 4: Associating by allocating the same uplink resources, such as allocating the same PUCCH or PUSCH resources.

在一些实施例中，上述SD basis/FD basis/DD basis的指示也可替换为端口选择指示。In some embodiments, the above-mentioned SD basis/FD basis/DD basis indications may also be replaced by port selection indications.

在一些实施例中，上述的CSI上报并不是总是包含上述所有的指示信息，在某些网络参数配置下部分指示信息不上报给网络侧。In some embodiments, the above-mentioned CSI reporting does not always include all of the above-mentioned indication information, and part of the indication information is not reported to the network side under certain network parameter configurations.

为了更清楚地理解上述方案，下面提供几个示例性的实施例，下述的实施例中只是以某种码本类型的CSI反馈进行举例，某一实施例中所述的SD/FD/DD basis、组合系数等指示信息的上报方法也可能适用于其它Type II码本类型的CSI上报。In order to understand the above scheme more clearly, several exemplary embodiments are provided below. The following embodiments only take CSI feedback of a certain codebook type as an example. The reporting method of indication information such as SD/FD/DD basis and combination coefficient described in a certain embodiment may also be applicable to CSI reporting of other Type II codebook types.

实施例1(基于Rel-16 Type II码本的CSI反馈)Example 1 (CSI feedback based on Rel-16 Type II codebook)

目前基于Rel-16 Type II码本的CSI反馈包括CSI Part 1和CSI Part 2两部分上报，CSI上报是通过承载于PUSCH的半持续或非周期的方式上报。CSI Part 1和CSI Part 2中可能包含的内容分别如表7所示。Currently, the CSI feedback based on Rel-16 Type II codebook includes two parts, CSI Part 1 and CSI Part 2. CSI reporting is carried out in a semi-continuous or non-periodic manner on PUSCH. The contents that may be included in CSI Part 1 and CSI Part 2 are shown in Table 7.

表7：相关技术中Rel-16 Type II码本的两个CSI部分上报内容
Table 7: Contents reported in two CSI parts of Rel-16 Type II codebook in related art

在每次CSI上报中，CSI Part 1和CSI Part 2需要同时上报。由于SD basis和FD basis变化缓慢，或者在一定的时间范围内基本保持不变，所以在此时间范围内只需上报一次SD basis和FD basis即可，这样可减少UE的反馈开销。In each CSI report, CSI Part 1 and CSI Part 2 need to be reported at the same time. Since SD basis and FD basis change slowly or remain basically unchanged within a certain time range, SD basis and FD basis only need to be reported once within this time range, which can reduce the feedback overhead of UE.

假设gNB给UE配置了CSI report1和CSI report 2。RI、CQI、非零系数个数指示信息、SCI和非零系数等指示信息以承载于PUSCH通过非周期的CSI report 1上报，且这些指示信息通过两部分上报，可以依据上表7所示。而SD basis和FD basis以承载于Long PUCCH通过周期或半持续CSI report 2上报，SD basis和FD basis的指示信息通过一个CSI部分独立上报。其中FD basis指示信息包括最大支持的rank下每层对应的FD basis。如最大支持rank＝4，该CSI部分包括4层对应的FD basis指示信息。Assume that the gNB configures CSI report 1 and CSI report 2 for the UE. RI, CQI, non-zero coefficient number indication information, SCI and non-zero coefficient indication information are reported through non-periodic CSI report 1 carried on PUSCH, and these indication information are reported in two parts, as shown in Table 7 above. SD basis and FD basis are reported through periodic or semi-continuous CSI report 2 carried on Long PUCCH, and the indication information of SD basis and FD basis is reported independently through a CSI part. The FD basis indication information includes the FD basis corresponding to each layer under the maximum supported rank. If the maximum supported rank = 4, the CSI part includes the FD basis indication information corresponding to 4 layers.

可选地，RI和SD basis、FD basis的指示信息通过一个配置的CSI report上报，并且通过CSI Part 1和CSI Part 2两部分上报，其中CSI Part 1中包括RI，或者包括RI和SD basis指示信息。CSI Part 2中包括rank＝v＝4时每层对应的FD basis指示信息。Optionally, the indication information of RI and SD basis and FD basis is reported through a configured CSI report, and is reported through CSI Part 1 and CSI Part 2, wherein CSI Part 1 includes RI, or includes RI and SD basis indication information. CSI Part 2 includes FD basis indication information corresponding to each layer when rank=v=4.

UE或gNB根据Rel-16 Type II码本结构计算预编码时，需要保证组合系数和SD/FD basis即W₁/W_f相匹配或相关联，是因为的计算取决于终端101所选的W₁和W_f。如果计算预编码时所用和W₁/W_f没有关联关系，将导致计算的预编码错误，降低系统性能。可选地，可以定义计算或者上报的与该上报之前且与上报该最近的一次SD/FD basis上报相关联(对应前述方案中的两个不同的CSI上报相关联方式的方式2)，也就是，在UE侧是通过上述定义的关联关系确定的W₁和W_f计算得到。而在网络侧，gNB根据接收的组合系数相关等指示信息和与之相关联的 SD basis、FD basis等指示信息分别确定W₁和W_f，并用于计算下行数据的预编码。UE or gNB uses Rel-16 Type II codebook structure When calculating precoding, it is necessary to ensure that the combination coefficient It matches or is related to the SD/FD basis, i.e., W ₁ /W _f , because The calculation of depends on _W1 and _Wf selected by terminal 101. If the precoding is calculated using There is no correlation with W ₁ /W _f , which will lead to errors in the calculated precoding and reduce system performance. Optionally, you can define the calculation or reporting With this report Before and with the report The most recent SD/FD basis report is associated (corresponding to the two different CSI report association methods in the above scheme 2), that is, on the UE side It is calculated by _W1 and _Wf determined by the association relationship defined above. On the network side, gNB receives the combination coefficient related information and the associated SD basis, FD basis and other indication information are determined separately W ₁ and W _f are used to calculate the precoding of downlink data.

实施例2(中高速移动场景下基于Rel-18 Type II码本的CSI反馈)Example 2 (CSI feedback based on Rel-18 Type II codebook in medium and high speed mobile scenarios)

目前中高速移动场景下基于Rel-18 Type II码本的CSI反馈包括CSI Part 1和CSI Part 2两部分上报，CSI上报是通过承载于PUSCH的半持续或非周期的方式上报。CSI Part 1和CSI Part 2中可能包含的内容分别如表8所示。Currently, the CSI feedback based on Rel-18 Type II codebook in medium and high-speed mobile scenarios includes two parts: CSI Part 1 and CSI Part 2. CSI reporting is reported in a semi-continuous or non-periodic manner carried on PUSCH. The contents that may be included in CSI Part 1 and CSI Part 2 are shown in Table 8.

实施例4(基于Rel-17 Type II端口选择码本的CSI反馈)Example 4 (CSI feedback based on Rel-17 Type II port selection codebook)

CSI reporting is reported in a semi-continuous or non-periodic manner carried on PUSCH. The contents that may be included in CSI Part 1 and CSI Part 2 are shown in Table 10.

表10：相关技术中Rel-17 Type II端口选择码本的两个CSI部分上报内容

Table 10: Contents reported in two CSI parts of the Rel-17 Type II port selection codebook in the related art

假设gNB给UE配置CSI report1和CSI report 2。RI、CQI、非零系数个数指示信息、SCI和非零系数等指示信息以承载于PUSCH通过非周期的CSI report 1上报，且这些指示信息通过两部分上报，可以依据上表10所示。而端口选择指示和FD basis以承载于Long PUCCH通过周期或半持续CSI report 2上报，端口选择和FD basis的指示信息通过一个CSI部分独立上报。假设RI与端口选择指示、FD basis指示信息通过一个CSI report上报，它也可通过一个CSI部分上报，是因为端口选择指示与FD basis指示和rank的值无关。Assume that the gNB configures CSI report 1 and CSI report 2 for the UE. RI, CQI, non-zero coefficient number indication information, SCI and non-zero coefficient indication information are reported through non-periodic CSI report 1 carried on PUSCH, and these indication information are reported through two parts, as shown in Table 10 above. The port selection indication and FD basis are reported through periodic or semi-continuous CSI report 2 carried on Long PUCCH, and the port selection and FD basis indication information are reported independently through a CSI part. Assuming that RI is reported through a CSI report with the port selection indication and FD basis indication information, it can also be reported through a CSI part because the port selection indication is independent of the FD basis indication and the rank value.

UE或gNB根据Rel-17 Type II码本结构计算预编码时，需要保证组合系数和端口选择/FD basis即W₁/W_f相匹配或相关联。假设端口选择和FD basis指示信息通过周期发送的或半持续发送的第一CSI上报，在第一CSI的一个周期内，首先上报端口选择和FD basis指示信息，然后再上报组合系数指示量化信息。其中，上报的组合系数的指示量化信息与该周期内上报的端口选择和FD basis的指示信息相关联(对应前述方案中的两个不同的CSI上报相关联方式的方式3)。也就是，在终端侧，是通过上述定义的关联关系确定的W₁和W_f计算得到。而在网络侧，gNB根据接收的组合系数相关等指示信息和与之相关联的端口选择、FD basis等指示信息分别确定W₁和W_f，并用于计算下行数据的预编码。UE or gNB uses Rel-17 Type II codebook structure When calculating precoding, it is necessary to ensure that the combination coefficient and port selection/FD basis, i.e., W ₁ /W _f, are matched or associated. Assuming that the port selection and FD basis indication information is reported through a first CSI report that is periodically or semi-continuously sent, within a period of the first CSI, the port selection and FD basis indication information is first reported, and then the combination coefficient indication quantization information is reported. Among them, the reported combination coefficient indication quantization information is associated with the port selection and FD basis indication information reported within the period (corresponding to the two different CSI reporting association methods in the aforementioned scheme 3). That is, on the terminal side, It is calculated by _W1 and _Wf determined by the association relationship defined above. On the network side, gNB determines the received combination coefficient related indication information and the associated port selection, FD basis and other indication information respectively. W ₁ and W _f are used to calculate the precoding of downlink data.

在一些实施例中，上述的CSI上报并不是总是包含所有的指示信息，在某些网络参数配置下部分指示信息不上报给网络侧。In some embodiments, the above-mentioned CSI reporting does not always include all indication information, and part of the indication information is not reported to the network side under certain network parameter configurations.
