[0074] Current CSI reporting only has UCI design based on a single CRI, and there is no UCI design based on multiple CRIs of different codebooks (for example, Type I single-panel codebook, eType II codebook). The specific UCI design corresponding to the multi-CRI reporting based on different codebooks needs to be defined by the protocol, mainly including UCI structure design (for example, whether the specific UCI is one part CSI or 2 part CSI, and if it is the latter, what information does part 1 CSI and part 2 CSI contain respectively), UCI mapping order design (for example, the arrangement order between various reporting quantities (for example, CRI, RI, PMI, CQI, LI) and the arrangement order of reporting multiple reporting quantities of the same type), priority and discard rules.

[0075] Embodiments of the present disclosure are described below with reference to the accompanying drawings. The information transmission method, apparatus, terminal and network device provided by the embodiments of the present disclosure can be applied to a wireless communication system. The wireless communication system can be a system using a fifth generation (5th Generation, 5G) mobile communication technology (hereinafter referred to as a 5G system), and those skilled in the art can understand that the 5G NR system is only an example and is not limited.

[0076] Referring to FIG. 1, FIG. 1 is a structure diagram of a network system to which embodiments of the present disclosure can be applied. As shown in FIG. 1, the network system includes a user terminal 11 and a base station 12. The user terminal 11 can be a user equipment (User Equipment, UE), for example, a terminal-side device such as a mobile phone, a tablet personal computer (Tablet Personal Computer), a laptop computer (Laptop Computer), a personal digital assistant (personal digital assistant, PDA), a mobile Internet device (Mobile Internet Device, MID), or a wearable device. It should be noted that the specific type of the user terminal 11 is not limited in the embodiments of the present disclosure. The base station 12 can be a base station of 5G and later versions (for example, gNB, 5G NR NB), or a base station in other communication systems, or a node B.

[0077] The embodiments of the present disclosure provide an information transmission method, apparatus, terminal and network device to realize UCI transmission of multiple CRIs.

[0078] The method and the device are based on the same disclosure concept, and the implementation of the device and the method can be referred to each other because the principles of solving problems are similar, and the repeated parts will not be described again.

[0079] As shown in FIG. 2, the information transmission method provided by the embodiment of the disclosure is executed by a terminal, and includes the following steps.

[0080] In step S201, according to a CRI report corresponding uplink control information (UCI) structure and UCI mapping order, determine the channel state information (CSI) report information corresponding to the multiple CRI reports.

[0081] In some embodiments, the UCI structure is used to define the structure of the reporting quantity contained in each CSI report, for example, whether the CSI report is composed of one part or multiple parts, and what reporting quantity is contained in each part. In some embodiments, the UCI mapping order refers to how the reporting quantity corresponding to each CRI is mapped into the UCI bit.

[0082] In some embodiments, the multiple CRI reports refer to the reports containing multiple reporting quantities associated with multiple CSI resources, that is, the CSI report in the embodiment of the disclosure includes multiple reporting quantities corresponding to multiple CRIs. In some embodiments, the reporting quantity includes at least one of the following:

[0083] CRI, rank indicator (RI), channel quality indicator (CQI), precoding matrix indicator (PMI), and layer indicator (LI).

[0084] In step S202, send the CSI report information to a network device.

[0085] It should be noted that the CSI report information can include one or more CSI reports, and each CSI report corresponds to multiple reporting quantities associated with multiple CSI resources obtained through one measurement.

[0086] In some embodiments, the terminal can send the CSI report information to the network device through a media access control control element (MAC-CE), or also through radio resource control (RRC) signaling.

[0087] It should be noted that, in the embodiment of the present disclosure, the CSI report information corresponding to the multi-CRI report is determined based on the UCI structure and the UCI mapping order corresponding to the multi-CRI report, and the CSI report information is sent to the network device, so that the multi-CRI reporting can be realized, and the communication flexibility is improved.

[0088] In some embodiments, in an implementation, the CSI report information corresponding to the multi-CRI report is determined according to the UCI structure and the UCI mapping order corresponding to the multi-channel state information resource indication (CRI) report, including:

[0089] The configuration parameter sent by the network device is received, and the configuration parameter is used to indicate whether the multi-CRI needs to be reported;

[0090] In the case where the configuration parameter indicates that the multi-CRI needs to be reported, the CSI report information corresponding to the multi-CRI report is determined according to the UCI structure and the UCI mapping order corresponding to the multi-CRI report.

[0091] In this case, it can be understood that the network device indicates to the terminal whether the multi-CRI needs to be reported, and only in the case where the multi-CRI needs to be reported, the terminal determines the CSI report information corresponding to the multi-CRI report based on the UCI structure and the UCI mapping order corresponding to the multi-CRI report; through the network device notification mode, the consistency of understanding between the terminal and the network device side can be ensured.

[0092] In some embodiments, the configuration parameter includes at least one of the following:

[0093] A11, CSI report type indication information, the CSI report type indication information is used to indicate that the multi-CRI needs to be reported;

[0094] It should be noted that in this case, a single indication information is used to indicate whether the CSI report type is multi-CRI reporting, for example, a bit can be used for indication, when the bit value is 1, it represents multi-CRI reporting, and when the bit value is 0, it represents single-CRI reporting; or, when the bit value is 0, it represents multi-CRI reporting, and when the bit value is 1, it represents single-CRI reporting.

[0095] A12, CSI report codebook type indication information, the CSI report codebook type indication information is used to indicate the codebook type of the CSI report and whether the multi-CRI needs to be reported based on the codebook type;

[0096] It should be noted that in this case, the indication of reporting multiple CRIs is performed through the codebook. Due to the different structures of different codebooks, the structure of the codebook can reflect whether it is multiple-CRI reporting. After receiving the CSI reporting codebook type indication information, the terminal can not only determine which codebook is used for reporting, but also determine whether it is multiple-CRI reporting.

[0097] For example, the codebook type can include a multiple-CRI type of Type I single-panel codebook or a multiple-CRI type of eType II.

[0098] A13, CRI number indication information, the CRI number indication information is used to indicate the number of reported CRIs;

[0099] In some embodiments, in this case, the CRI number indication information is used to indicate the number of CRIs, and the number of CRIs indicated by the CRI number indication information is usually greater than or equal to 2.

[0100] In some embodiments, in one implementation, in the case where the configuration parameter is used to indicate that multiple CRIs need to be reported, the CRI number indication information usually needs to be included in the configuration parameter; of course, the CRI number indication information can also be implicitly indicated as multiple-CRI reporting, and therefore, the configuration parameter can only include A13.

[0101] In some embodiments, in the case where the configuration parameter is used to indicate that multiple CRIs need to be reported, the configuration parameter can include A11 and A13, can also include A12 and A13, can also include A11, A12 and A13, or can only include A13.

[0102] It should be noted that in order to ensure that the terminal can accurately determine the corresponding CSI reporting information of the multiple-CRI reporting, the network device usually also needs to configure the terminal with parameters such as reporting bearing channel type, reporting frequency domain granularity, and reporting time domain behavior.

[0103] It should be noted that the embodiments of the present disclosure are mainly applicable to the following cases:

[0104] Case 1, multiple-CRI reporting based on periodic or semi-persistent and wideband reporting frequency domain granularity;

[0105] It should be noted that this case can be understood as multiple-CRI reporting based on the wideband frequency domain granularity of the physical uplink shared channel (PUCCH).

[0106] Case 2, multiple-CRI reporting based on aperiodic, wideband reporting frequency domain granularity, and the network device side configures the terminal to report M R CSI-RS resources.

[0107] It should be noted that this case can be understood as being based on a physical uplink shared channel (PUSCH), and the network device side configures the terminal to report M R CSI-RS resources with a wideband frequency domain granularity.

[0108] It should be noted that the above-mentioned case 1 and case 2 are applicable to Type I single-panel codebook.

[0109] Case 3, based on aperiodic, reporting a frequency domain granularity of a subband, and the network device side configures the terminal to report M R CSI-RS resources with multi-CRI reporting;

[0110] It should be noted that this case can be understood as being based on a PUSCH channel, and the network device side configures the terminal to report M R CSI-RS resources with subband frequency domain granularity multi-CRI reporting.

[0111] Case 4, based on aperiodic reporting, reporting a frequency domain granularity of a subband, and the network device side configures the terminal to report M R CSI-RS resources with multi-CRI reporting;

[0112] It should be noted that this case can be understood as being based on a PUSCH channel, and the network device side configures the terminal to report M R CSI-RS resources with subband frequency domain granularity multi-CRI reporting.

[0113] It should be noted that the difference between case 3 and case 4 is that the codebooks corresponding to the two cases are different, and case 3 can be understood as corresponding to Type I single-panel codebook, and case 4 can be understood as corresponding to eType II codebook.

[0114] The different cases will be described in detail below from the perspectives of UCI structure, UCI mapping order, priority and discard rule.

[0150] Wherein, M is an integer greater than or equal to 2, and M R is an integer greater than or equal to 1.

[0151] It should be noted that the UCI structure contains the relevant reporting quantity in B21-B27 only when the network device indicates that the corresponding reporting quantity needs to be carried.

[0152] It should be noted here that one RI, LI, PMI and / or CQI can be calculated based on each CRI-associated CSI-RS resource, and the RI, LI, PMI and / or CQI calculated for each CSI-RS resource are independent. In some embodiments, the reporting of the above-mentioned M CRIs, at least one RI, M LIs, M PMIs and M CQIs is independent, that is, the M CRIs, at least one RI, M LIs, M PMIs and M CQIs in the UCI structure in this case are reported respectively.

[0174] B311, M groups of odd subband differential CQI associated with the second TB;

[0175] B312, M groups of odd subband PMI second information fields;

[0176] wherein M is an integer greater than or equal to 2, M R is an integer greater than or equal to 1.

[0177] It should be noted that only when the network device indicates that the corresponding report quantity needs to be carried, the UCI structure in this case contains the relevant report quantity in B31-B312.

[0178] It should be noted here that based on each CRI associated CSI-RS resource, an RI, LI, PMI and / or CQI can be calculated, and the RI, LI, PMI and / or CQI calculated for each CSI-RS resource is independent. In some embodiments, the reporting of the above-mentioned M CRIs, at least one RI, M LIs, M PMIs, and M CQIs is independent, that is, in the UCI structure in this case, the M CRIs, at least one RI, M LIs, M PMIs, and M CQIs are reported respectively.

[0179] It should be noted that the CSI reporting in this case 3 is composed of two parts, wherein the second part contains a subband part and a wideband part; the UCI design in this case 3 has a fixed first part CSI overhead for each CSI report, and the overhead size of the second part CSI can be determined according to the first part CSI.

[0180] Case 4, based on aperiodic reporting, reporting frequency domain granularity is subband, and the network device side configures M R CSI-RS resource multiple CRI reporting

[0181] In some embodiments, in this case, the UCI structure includes a first part CSI and a second part CSI;

[0182] The first part of the CSI includes at least one of the following:

[0183] B41, M CRI or M-M R CRI;

[0184] It should be noted that M mentioned in the embodiments of the present disclosure is the number of CRI to be reported, which is configured by the network device through RRC. In some embodiments, M is an integer greater than or equal to 2. M R is the number of CSI-RS resources that the network device indicates that the terminal must report, which is configured by the network device through RRC; in some embodiments, the information that the network device indicates that the terminal must report M R CSI-RS resources is configured by RRC, and M R is an integer greater than or equal to 1.

[0185] It should be noted that if the network device indicates the information of M R CSI-RS resources that the terminal must report, the CRI associated with the M R CSI-RS resources is known to the network device, and the terminal can not report it, so the number of reported CRIs is (M-M R ) at this time. However, the terminal still needs to calculate and report the RI, LI, PMI and / or CQI associated with the M R CSI-RS resources. When reporting the M R RI, LI, PMI and / or CQI, because the corresponding CRI is not reported, the network device and the terminal need to have consistent understanding of the arrangement order of the M R RI, LI, PMI and / or CQI associated with the CSI-RS resources. The specific order can be the order of the ID of the CSI-RS resource, or according to the time order of the corresponding CSI-RS resource configuration, or according to the indication order of the M R CSI-RS resources indicated by the network.

[0186] In some embodiments, if (M-M R ) CRIs are reported, these CRIs are selected from K s CSI-RS resources configured by the network device for the terminal, excluding the M R CSI-RS resources that the network device indicates that the terminal must report. s R

[0187] B42, at least one RI;

[0188] ​​In some embodiments, the number of RIs in the present disclosure can be one, i.e., only one RI is reported to represent the RIs corresponding to all M CSI-RS resources; the number of RIs in the present disclosure can be M, i.e., M CSI-RS resources independently calculate RIs; of course, the M CSI-RS resources can also be grouped in the present disclosure, each group corresponds to one RI, and the number of groups is greater than or equal to 1 and less than or equal to M.

[0189] B43, M wideband CQIs associated with the first TB;

[0190] B44, M groups of subband differential CQIs associated with the first TB;

[0191] B45, M total numbers of non-zero coefficients of all layers;

[0192] The second part of the CSI includes at least one of the following:

[0193] B46, M PMI first information domains;

[0194] In some embodiments, the PMI first information domain includes at least one of the following:

[0195] Spatial domain basis vector indication, rotation factor, and strongest coefficient indicator (SCI) of each layer.

[0196] B47, M high-priority PMI second information domains;

[0197] In some embodiments, the high-priority PMI second information domain includes at least one of the following:

[0198] Frequency domain basis vector indication, initial value of intermediate basis vector set, start position indication of intermediate basis vector set (i.e., M initial ), reference amplitude, high-priority non-zero coefficient, and non-zero coefficient position indication corresponding to the high-priority non-zero coefficient.

[0199] B48, M low-priority PMI second information domains;

[0200] In some embodiments, the low-priority PMI second information domain includes at least one of the following:

[0201] Low-priority non-zero coefficient and low-priority non-zero coefficient position indication.

[0202] It should be noted that only when the network device indicates that the corresponding report quantity needs to be carried, the UCI structure will include the related report quantity in B31-B312.

[0203] It should be noted that, based on the CSI-RS resource associated with each CRI, one RI, LI, PMI and / or CQI can be calculated, and the RI, LI, PMI and / or CQI calculated for each CSI-RS resource is independent. In some embodiments, the reporting of the M CRIs, at least one RI, M LIs, M PMIs and M CQIs is independent, i.e., in the UCI structure in this case, the M CRIs, at least one RI, M LIs, M PMIs and M CQIs are reported respectively.

[0204] It should be noted that the CSI reporting in this case 4 is composed of two parts, and the UCI design in this case 4 is that the first part of the CSI reporting has a fixed overhead, and the overhead of the second part of the CSI reporting can be determined according to the first part of the CSI reporting.

[0205] II. UCI mapping order

[0206] In some embodiments, in one implementation, the UCI mapping order includes one of C11 and C12:

[0207] C11, the mapping of all the reported quantities contained in each CRI is performed in order of the CRIs, and the order of the CRIs is determined based on the index order of the CSI-RS resources associated with the CRIs or the configuration order of the CSI-RS resources;

[0208] This mode can be understood as that after the mapping of all the reported quantities associated with the same CRI is completed, the mapping of all the reported quantities associated with the next CRI is performed, for example, for M CRIs, the mapping order of the reported quantities is: CRI-1 (i.e., the first CRI), RI-1 (i.e., the RI corresponding to the first CRI), LI-1 (i.e., the LI corresponding to the first CRI), PMI-1 (i.e., the PMI corresponding to the first CRI), CQI-1 (i.e., the CQI corresponding to the first CRI), CRI-2 (i.e., the second CRI), RI-2 (i.e., the RI corresponding to the second CRI), LI-2 (i.e., the LI corresponding to the second CRI), PMI-2 (i.e., the PMI corresponding to the second CRI), CQI-2 (i.e., the CQI corresponding to the second CRI), …, CRI-M (i.e., the Mth CRI), RI-M (i.e., the RI corresponding to the Mth CRI), LI-M (i.e., the LI corresponding to the Mth CRI), PMI-M (i.e., the PMI corresponding to the Mth CRI), CQI-M (i.e., the CQI corresponding to the Mth CRI).

[0209] In some embodiments, if the mapping of all the reporting quantities contained in each CRI is sequentially performed according to the order of the CRIs, the zero padding bit string in the CSI report information is divided into M bit strings, and each bit string corresponds to one CRI; or

[0210] If the mapping of all the reporting quantities contained in each CRI is sequentially performed according to the order of the CRIs, the zero padding bit string in the CSI report information is one continuous bit string.

[0211] That is, for the above case 1, because the UCI structure contains a zero padding bit string, under this mapping order, the zero padding bit string can be segmented and padded for each CRI. In the case of segmented padding, the padding can be performed after the mapping of the reporting quantity of one CRI, and then the reporting quantity of the next CRI is mapped. The zero padding bit string can also be collectively padded for all CRIs. In some embodiments, the position of the zero padding bit string under this padding mode is flexible. The zero padding bit string can be placed between two CRIs, or the zero padding bit string can be placed after the reporting quantity of the last CRI. Here, this is only an example of the placement position of the zero padding bit string, and does not constitute a limitation on the protection scope of the embodiments of the present disclosure.

[0212] C12, sequentially mapping, according to the order of the reporting quantities, the same reporting quantity corresponding to all the CRIs corresponding to each reporting quantity;

[0213] This mode can be understood as first mapping one reporting quantity corresponding to all the CRIs, and then mapping the next reporting quantity corresponding to all the CRIs. For example, for M CRIs, the mapping order of the reporting quantities is: CRI-1, …, CRI-M, RI-1, …, RI-M, …, CQI-1, …, CQI-M.

[0214] In some embodiments, this case can be understood as mapping according to the type of the reporting quantity, that is, after mapping all the reporting quantities of the same type corresponding to all the CRIs, the reporting quantity of the next type corresponding to all the CRIs is mapped.

[0215] It should be noted that the order of the reporting quantities in the embodiments of the present disclosure can be protocol-conventionally (protocol-predefined) or indicated by a network device. For example, the network device side numbers each reporting quantity and indicates that the order of the reporting quantities is from small to large according to the number.

[0216] In some embodiments, if the mapping of all the reporting quantities corresponding to each reporting quantity corresponding to all the CRIs is sequentially performed according to the order of the reporting quantities, the zero padding bit string in the CSI report information is one continuous bit string.

[0217] In other words, for situation 1 above, since the UCI structure contains a zero-padding bit string, under this mapping order, the zero-padding bit string can be centrally padded for all CRIs. In some embodiments, the position of the zero-padding bit string under this supplementation method is more flexible. The zero-padding bit string can be placed between two CRIs, or it can be placed after the reported amount of the last CRI. This is just an example of the placement of the zero-padding bit string and does not constitute a limitation on the protection scope of the embodiments of this disclosure.

[0218] It should be noted that, for case 1 above, the mapping order includes one of C11 and C12 mentioned above.

[0219] In some embodiments, for case 2 above, in addition to following C11 or C12 as described above, the UCI mapping order also includes the following:

[0220] C21. First, map the terminal and select the MM to report. R The reported volume associated with each CRI is then mapped to the M that the terminal needs to report, configured on the network device side. R The number of reports associated with each CSI-RS resource;

[0221] This situation can be understood as first mapping the terminal to select the MM to report. R After mapping all the reported data associated with each CRI selected by the terminal, the network device configuration for the M data that the terminal needs to report is then mapped. R The number of reports associated with each CSI-RS resource.

[0222] In some embodiments, for MM R For mapping of reported quantities associated with each CRI, the terminal can choose to use C11 or C12 for mapping; for M R The reporting terminals associated with each CSI-RS resource can choose to use C11 or C12 for mapping.

[0223] C22. First, map the M configuration configured on the network device side to the terminal that needs to be reported. R The reported volume associated with each CSI-RS resource is then mapped to the MM selected for reporting by the terminal. R The number of reports associated with each CRI;

[0224] This situation can be understood as first mapping the network device configuration to the M that the terminal needs to report. R The reported volume associated with each CSI-RS resource, in the network device configuration terminal needs to report M R After all the reported volumes associated with each CSI-RS resource have been mapped, the terminal then selects the MM to report.R a reporting quantity associated with M

[0225] It should be noted that by configuring the network side to the terminal the CRI corresponding to the CSI-RS to be reported and the CRI selected by the terminal to be reported are divided into two categories, and the priority of the two categories of CRIs is defined, which can flexibly map the reporting quantity, and because the reporting quantity mapped later may be discarded due to insufficient resources, therefore, this way can avoid important CRIs being discarded, thereby ensuring the reliability of CRI reporting.

[0226] In some embodiments, for a reporting quantity associated with M R CSI-RS resources, the terminal can select to use C11 or C12 for mapping; for a reporting quantity associated with M-M R CSI-RS resources, the terminal can select to use C11 or C12 for mapping.

[0227] In some embodiments, the order of the M R CSI-RS resources associated with the reporting quantity includes one of the following:

[0228] C31, the order of CSI-RS resource identification;

[0229] C32, the order of CSI-RS resource configuration time;

[0230] C33, the indication order of the CSI-RS resource;

[0231] In some embodiments, the indication order refers to the order of the CSI-RS resource indicated by the network device to the terminal.

[0232] In some embodiments, in one implementation, the method further includes:

[0233] receiving M R CSI-RS resources that the terminal needs to report sent by the network device, the M R CSI-RS resources are identified according to a first order, and the first order includes at least one of the following:

[0234] the order of CSI-RS resource identification;

[0235] the order of CSI-RS resource configuration time;

[0236] the indication order of the CSI-RS resource.

[0237] It should be noted that the CSI-RS resources that the terminal needs to report need to be notified to the terminal by the network device, and when notifying, the CSI-RS resource identification, CSI-RS resource configuration time, etc. can be notified. The terminal and the network deviceR For example, the network device can notify the CSI-RS resources in the order of CSI-RS resource identification, and the terminal receiving the CSI-RS resources also identifies the M R For example, the network device can notify the CSI-RS resources in the order of CSI-RS resource configuration time, and the terminal receiving the CSI-RS resources also identifies the M R For example, the network device can indicate the CSI-RS resources one by one, and the terminal receiving the CSI-RS resources identifies the M R CSI-RS resources in the order of indication.

[0238] In some embodiments, for case 3 described above, in addition to the UCI mapping order according to C11 or C12 described above and according to C21 or C22 described above, the UCI mapping order further includes:

[0239] First, map the reporting quantity corresponding to the even subband associated with the M CSI-RS resources, and then map the reporting quantity corresponding to the odd subband associated with the M CSI-RS resources.

[0240] It should be noted that, because the second part of the UCI structure of case 3 contains a wideband part and a subband part, and the subband part can be further divided into even subbands and odd subbands, the order of different types of subbands can also be defined when mapping. In some embodiments, in this way, the even subband reporting quantity (i.e., even subband differential CQI and / or even subband PMI) associated with the M CSI-RS resources is first mapped, and then the odd subband reporting quantity (i.e., odd subband differential CQI and / or odd subband PMI) associated with the M CSI-RS resources is mapped.

[0241] It should be noted that the mapping order of the M CSI-RS resources described above can use C21 or C22 described above, and the network device indicates the mapping order of the M R CSI-RS resources that the terminal must report can use any of C31 to C33 described above.

[0242] In some embodiments, for case 4 described above, in addition to the UCI mapping order according to C11 or C12 described above and according to C21 or C22 described above, the UCI mapping order further includes:

[0243] Group the second part of CSI according to the priority from high to low, and map according to the priority.

[0244] It should be noted that in this case, the mapping is based on grouping, that is, different groups correspond to different priorities, and the mapping of high-priority groups is performed first, and then the mapping of low-priority groups is performed.

[0245] Specifically, the mapping priority corresponding to the group number from small to large is from high to low.

[0246] It should be noted that by grouping the reported quantity and defining the mapping priority based on grouping, the mapping priority of the more important reported quantity can be defined to be higher, so as to avoid the important reported quantity from being discarded in the case of insufficient resources.

[0247] In some embodiments, in an implementation, the grouping of the second part of CSI includes one of the following:

[0248] C41, the second part of CSI is divided into three groups, the first group contains the PMI first information field associated with the first CRI to the Mth CRI, the second group contains the high-priority PMI second information field associated with the first CRI to the Mth CRI, and the third group contains the low-priority PMI second information field associated with the first CRI to the Mth CRI;

[0249] It should be noted that in this case, the grouping is performed according to the types of the reported quantities contained in the second part of CSI. Since the second part of CSI in the UCI structure in case 4 contains at most three types of reported quantities, i.e., PMI first information field, high-priority PMI second information field, and low-priority PMI second information field, this grouping method is to divide different types of reported quantities into different groups. It should be noted that since reporting may not exist for some types of reported quantities, grouping is performed only according to the reported quantities that need to be reported. That is, the second part of CSI is divided into at most three groups in the embodiment of the present disclosure.

[0250] For example, if the second part of CSI contains PMI first information field, high-priority PMI second information field, and low-priority PMI second information field, the second part of CSI is divided into Group0, Group1, and Group2, a total of 3 groups, Group0 contains PMI first information field associated with the first CRI to the Mth CRI; Group1 contains high-priority PMI second information field associated with the first CRI to the Mth CRI; Group2 contains low-priority PMI second information field associated with the first CRI to the Mth CRI; and the mapping is performed according to Group0, Group1, and Group2.

[0251] C42, the second part of CSI is divided into five groups, the first group contains the PMI first information domain associated with the first CRI to the Mth CRI, the second group contains the high priority PMI second information domain associated with the first CRI to the Mth CRI, the third group contains the high priority PMI second information domain associated with the Mth CRI to the Mth CRI, the fourth group contains the low priority PMI second information domain associated with the first CRI to the Mth CRI, and the fifth group contains the low priority PMI second information domain associated with the Mth CRI to the Mth CRI. R R R R

[0252] It should be noted that this case is classified according to the types of reporting quantities contained in the second part of CSI, and the CRI reported by the network device and the CRI selected by the terminal for reporting. Since the second part of CSI in case 4 in the UCI structure contains at most three types of reporting quantities, i.e., the PMI first information domain, the high priority PMI second information domain, and the low priority PMI second information domain, and at most two types of CRIs, this grouping method is to group the reporting quantities of different types and the reporting quantities corresponding to different types of CRIs into different groups. It should be noted that since reporting, some types of reporting quantities may not exist, so when grouping, only the reporting quantities that need to be reported are grouped. That is, the second part of CSI is divided into at most five groups in the embodiment of the disclosure.

[0253] For example, if the second part of CSI contains three types of reporting quantities, i.e., the PMI first information domain, the high priority PMI second information domain, and the low priority PMI second information domain, the second part of CSI is divided into Group0, Group1, …, Group4, a total of 5 groups, Group0 contains the PMI first information domain associated with the first CRI to the Mth CRI; Group1 contains the high priority PMI second information domain associated with the first CRI to the Mth CRI; Group2 contains the high priority PMI second information domain associated with the Mth CRI to the Mth CRI; Group3 contains the low priority PMI second information domain associated with the first CRI to the Mth CRI; and Group4 contains the low priority PMI second information domain associated with the Mth CRI to the Mth CRI. R R R

[0254] ​​​​​​​C43, the second part of CSI is divided into 2M+1 groups, the first group contains the PMI first information field associated with the first CRI to the Mth CRI, the second group to the M+1th group respectively contains the high priority PMI second information field associated with the first CRI to the Mth CRI, and the M+2th group to the 2M+1th group respectively contains the low priority PMI second information field associated with the first CRI to the Mth CRI;

[0255] It should be noted that this case is classified according to the type of reporting quantity contained in the second part of CSI and each CRI. Since the second part of CSI in the UCI structure in case 4 contains at most three types of reporting quantities, i.e., PMI first information field, high priority PMI second information field, and low priority PMI second information field, and contains M CRIs, this grouping mode is to group different types of reporting quantities and different CRI corresponding reporting quantities into different groups. It should be noted that when reporting, some types of reporting quantities may not exist, so when grouping, only the reporting quantity that needs to be reported is grouped. That is, the second part of CSI is divided into 2M+1 groups in the embodiment of the disclosure, which means that the second part of CSI is at most divided into 2M+1 groups.

[0256] For example, if the second part of CSI contains PMI first information field, high priority PMI second information field, and low priority PMI second information field, the second part of CSI is divided into Group0, Group1, …, Group 2M, a total of 2M+1 groups, Group0 contains PMI first information field associated with the first CRI to the Mth CRI; Group1 to GroupM respectively contains high priority PMI second information field associated with the first CRI to the Mth CRI; GroupM+1 to Group2M contains low priority PMI second information field associated with the first CRI to the Mth CRI; and mapping is performed according to Group0, Group1, …, Group2M.

[0257] It should be noted that the mapping order of the above M CSI-RS resources can use the above C21 or C22, and the network device indicates the mapping order of the M R CSI-RS resources that the terminal must report can use any one of the above C31 to C33.

[0258] Three, priority and discard rule

[0259] In some embodiments, in an implementation, the determination of the channel state information, CSI, report information corresponding to the multi-CRI report includes one of D11, D12, and D13:

[0260] D11, determine the CSI report information corresponding to the multi-CRI report according to a first rule, the first rule comprising: mapping the reporting quantity of all CSI reports to a UCI bit sequence in ascending order of CSI report index, if CSI report dropping needs to be performed, dropping in descending order of the index value of the CSI report, the index value of the CSI report corresponding to the priority of the CSI report in descending order from large to small;

[0261] It should be noted that this way is to discard according to the CSI report, that is, a CSI report is discarded as a whole.

[0262] It should be noted that this way is applicable to the above-mentioned case 1.

[0263] D12, determine the CSI report information corresponding to the multi-CRI report according to a second rule;

[0264] The second rule comprises one of D121 and D122:

[0265] D121, mapping the first part CSI of all CSI reports to a first UCI bit sequence in ascending order of CSI report index, mapping the second part CSI of all CSI reports to a second UCI bit sequence in ascending order of CSI report index, if CSI report dropping needs to be performed, dropping the second part CSI of all CSI reports, and the second part CSI of all CSI reports has the same priority;

[0266] It should be noted that in this case, the terminal can discard the second part CSI, and the second part CSI of each report has the same priority (priority 0), if the number of reported information bits exceeds the channel capacity, CSI dropping needs to be performed, and all second part CSI of all CSI reports will be discarded.

[0267] It should be noted that this way is applicable to the above-mentioned case 2.

[0268] D122, mapping the first part CSI of all CSI reports to a first UCI bit sequence in ascending order of CSI report index, mapping the second part CSI of all CSI reports to a second UCI bit sequence in ascending order of CSI report index, if CSI report dropping needs to be performed, grouping the second part CSI, and dropping in ascending order of group number, the larger the group number, the higher the dropping priority;

[0269] The first UCI bit sequence and the second UCI bit sequence are independently encoded and transmitted.

[0270] It should be noted that in this case, the grouping of the second part of CSI is performed first, and then the dropping is performed based on the grouping, that is, the group with the lowest priority is dropped first, and then the group with the second-lowest priority is dropped, and so on.

[0271] It should be noted that by grouping the second part of CSI and defining the dropping priority based on the grouping, the dropping priority of the more important reporting quantity can be defined to be lower, so as to avoid the important reporting quantity from being dropped in the case of insufficient resources.

[0272] In some embodiments, for case 3 described above, in the case where the second part of CSI includes a second part of CSI wideband part and a second part of CSI subband part, the second part of CSI of all CSI reports is mapped to the second UCI bit sequence in the order of CSI report index from small to large, including:

[0273] The second part of CSI wideband part of all CSI reports is first mapped to the second UCI bit sequence in the order of CSI report index from small to large, and then the second part of CSI subband part of all CSI reports is mapped to the second UCI bit sequence in the order of CSI report index from small to large.

[0274] This mapping manner can be understood as that when mapping the CSI reports, the second part of CSI wideband part of all CSI reports is first mapped, and then the second part of CSI subband part of all CSI reports is mapped, and the mapping of each part is performed in the order of CSI report index.

[0275] In some embodiments, for case 2 described above, the grouping of the second part of CSI includes one of D12201 and D12202:

[0276] D12201, the second part of CSI is divided into two groups, the first group contains M R CSI-RS resource associated second part of CSI corresponding reporting quantity, and the second group contains M-M R CSI-RS resource associated second part of CSI corresponding reporting quantity;

[0277] It should be noted that in this case, the grouping is performed according to the CRI configured by the network device for the terminal to report and the CRI selected by the terminal to report, the second part of CSI corresponding to the reporting quantity corresponding to the CRI configured by the network device for the terminal to report is divided into a group, and the second part of CSI corresponding to the reporting quantity corresponding to the CRI selected by the terminal to report is divided into another group.

[0278] It should be noted that the terminal can discard part of the second part CSI, and the second part CSI in case 2 is divided into two groups: Group 1 contains M R CSI-RS resource associated second part CSI (LI / PMI / CQI) that the base station indicates the terminal must report, and Group 2 contains (M-M R ) CRI associated second part CSI (LI / PMI / CQI) that the terminal selects to report. The priority of Group 2 is higher than that of Group 1. When discarding, discard from low to high according to priority, and when discarding a certain priority second part CSI, the terminal needs to discard all the information of this priority.

[0279] It should be further noted here that the second part CSI of each CSI report contains 2 priority groups Group 1 and Group 2 corresponding to M R CSI-RS resources that the network device indicates the terminal must report and (M-M R ) CRI associated CSI-RS resources that the terminal selects to report, and when discarding, first discard all Group 1 corresponding to the CSI report, and then discard Group 2.

[0280] D12202, divide the second part CSI into M groups, each group corresponding to the reporting amount of the second part CSI associated with one CSI-RS resource, and the group number is sorted from small to large according to the order of M R CSI-RS resources first and then M-M R CSI-RS resources;

[0281] It should be noted that this case is to group each CRI respectively, that is, the reporting amount corresponding to each CRI respectively corresponds to a group.

[0282] It should be noted that the terminal can discard part of the second part CSI, and the second part CSI in case 2 is divided into M groups, that is, Group 1, …, Group M, each group contains the reporting amount (LI / PMI / CQI) of the second part CSI associated with one CSI-RS resource.

[0283] In some embodiments, the arrangement order of the M groups corresponding to the CSI-RS resources is arranged according to M R CSI-RS resources that the network device indicates the terminal must report, and then (M-M R ) CRI associated CSI-RS resources that the terminal selects to report. The arrangement order of the M R CSI-RS resources that the network device indicates the terminal must report can use any of C31 to C33 described above. The arrangement order of the (M-MR ) CSI-RS resources associated with the M CRIs are arranged in the order of priority from high to low according to the reporting order of the terminal. When discarding, the discarding is performed from low to high according to the priority, and when discarding the second part CSI of a certain priority, the terminal needs to discard all the information of the priority.

[0284] It needs to be further explained here that the second part CSI of each CSI report contains M priority groups Group1,…,Group M corresponding to each CSI-RS resource, and when discarding, the discarding is performed according to Group M, Group M-1,…,Group 1, that is, the second part CSI associated with the CSI-RS resource is discarded according to the priority one by one.

[0285] In some embodiments, for the above case 3, the grouping of the second part CSI includes one of D12211 to D12213:

[0286] D12211, the second part CSI wideband part corresponding to the M CRIs is divided into a group, and the second part CSI subband part corresponding to the M CRIs is divided into two groups, the first group contains the reporting quantity corresponding to the even subband part of the second part CSI subband part, and the second group contains the reporting quantity corresponding to the odd subband part of the second part CSI subband part;

[0287] It needs to be explained that because the second part CSI in case 3 is divided into a second part CSI wideband part and a second part CSI subband part, this case divides the wideband part into a group, and divides the subband part into two groups according to the odd subband and the even subband, and the priority of the second part CSI wideband part is always higher than the priority of the second part CSI subband part.

[0288] In some embodiments, the terminal can discard a part of the second part CSI, and the second part CSI wideband part of all CSI reports is the highest priority (priority 0), and then the second part CSI subband part of the even subband and the second part CSI subband part of the odd subband of the n=1,…,N rep CSI report have priority 2n-1 and priority 2n respectively. That is, in this case, the second part CSI wideband part of all CSI reports is divided into a group, which has the same priority, the second part CSI subband part is grouped according to the odd subband and the even subband, and all the groups of the CSI reports are numbered uniformly according to the CSI report index; the priority of priority 0 is the highest, and the priority of priority 2N repThe lowest priority is given to the CSI information. When discarding information, it is done from lowest to highest priority. When discarding the second part of CSI information of a specific priority, the terminal needs to discard all information of that priority.

[0289] D12212. Divide the second part of the CSI broadband portion corresponding to M CRIs into one group, and divide the second part of the CSI subband portion corresponding to M CRIs into four groups. The first group contains M R The second part of the even-numbered subbands associated with each CSI-RS resource corresponds to the reported volume of the second group, which includes MM. R The second part of the even-numbered subbands associated with each CSI-RS resource corresponds to the reported volume. The third group includes M. R The second part of the CSI subband associated with each CSI-RS resource corresponds to the reported volume. The fourth group includes MM. R The reported volume corresponding to the second part of the CSI subband portion of the odd-numbered subbands associated with each CSI-RS resource;

[0290] It should be noted that, since the second part of CSI in case 3 is further divided into the second part of CSI broadband and the second part of CSI sub-band, the broadband part is grouped together, and the sub-band part is divided into four groups according to odd sub-bands, even sub-bands, CRIs reported by network device configuration terminals, and CRIs reported by terminal selection. The priority of the second part of CSI broadband is always higher than that of the second part of CSI sub-band.

[0291] In some embodiments, the terminal may discard a portion of the second part of the CSI. All second part CSI broadband portions of the CSI reports have the highest priority (priority 0). The second part CSI subband portion of the CSI reports in each subsequent case 3 is further divided into four groups: Group 1 contains the M data that the base station instructs the terminal to report. R Group 2 comprises the reported volume (PMI / CQI) of the second part of the even-numbered subbands associated with each CSI-RS resource, including terminal-selected reported (MM) data. R Group 3 contains the reported amounts (PMI / CQI) of the second part of the even-numbered subbands associated with each CRI, and includes the M data that the network device instructs the terminal to report. R The reported volume (PMI / CQI) of the second part of the odd-numbered subbands associated with each CSI-RS resource, Group 4 includes the terminal-selected reported (MM) R) CSI subband parts of even subbands associated with each CSI-RS resource. The priority relationship is: Group 1 > Group 2 > Group 3 > Group 4. Then all the groups of CSI reports are numbered uniformly according to the CSI report index. When discarding, the discarding is performed from low to high priority. When discarding a certain priority second part CSI, the terminal needs to discard all the information of this priority.

[0292] D12213、the M CSI corresponding to the second part of the CSI wideband part is divided into a group, and the M CSI corresponding to the second part of the CSI subband part is divided into 2M groups, the first group to the Mth group corresponding to the reporting quantity of the second part of the CSI subband part associated with each CSI-RS resource, and the M+1th group to the 2Mth group corresponding to the reporting quantity of the second part of the CSI subband part associated with each CSI-RS resource;

[0293] It should be noted that, because the second part of the CSI in case 3 is divided into a second part of the CSI wideband part and a second part of the CSI subband part, this case divides the wideband part into a group, and divides the subband part into 2M groups according to odd and even subbands and each CRI, and the priority of the second part of the CSI wideband part is always higher than the priority of the second part of the CSI subband part.

[0294] In some embodiments, the terminal can discard a part of the second part of the CSI, and the second part of the CSI wideband part of all CSI reports is the highest priority (priority 0), and then the second part of the CSI subband part of each case 3 CSI report is divided into 2M groups, the first M groups, i.e. Group 1 to Group M, are the reporting quantities of the second part of the CSI subband part of even subbands associated with each CSI-RS resource (PMI / CQI), and the last M groups, i.e. Group M+1 to Group 2M, are the reporting quantities of the second part of the CSI subband part of odd subbands associated with each CSI-RS resource (PMI / CQI). The priority relationship is: Group 1 > … > Group 2M. The arrangement order of the M groups corresponding to the CSI-RS resource is first the M R CSI-RS resources that the network device instructs the terminal to report, and then the terminal selects the arrangement of (M-M R ) CSI-RS resources associated with the CRI. The arrangement order of the M R CSI-RS resources that the network device instructs the terminal to report can use any of C31 to C33 described above. The terminal selects the arrangement of (M-M R) CSI-RS resource arrangement order associated with CRI is arranged according to the reporting order priority of the terminal from high to low. Then all the groups of CSI reports are numbered uniformly according to the CSI report index. When discarding, the priority is from low to high, and when discarding the second part CSI of a certain priority, the terminal needs to discard all the information of this priority.

[0295] In some embodiments, for the above case 4, the grouping of the second part CSI of all CSI reports includes one of the following:

[0296] D12221, the PMI first information domain of the second part CSI of all CSI reports is divided into a group, and the PMI second information domain of each CSI report is divided into two groups according to the high priority PMI second information domain and the low priority PMI second information domain, and the priority is allocated from small to large according to the CSI report number and the group number corresponding to the CSI report from small to large, wherein the higher the priority value represents the lower the priority;

[0297] It should be noted that, in case 4, the second part CSI is divided into PMI first information domain, high priority PMI second information domain and low priority PMI second information domain. In this case, the PMI first information domain of all CSI reports is divided into a group, the high priority PMI second information domain and the low priority PMI second information domain of each CSI report are respectively grouped, and the group of each CSI report is numbered uniformly according to the CSI report number, and the priority of the PMI first information domain of the second part CSI is higher than that of the high priority PMI second information domain and the low priority PMI second information domain.

[0298] In some embodiments, the terminal can discard part of the second part CSI, and the second part CSI of the n=1,…,Nrep CSI reports is grouped according to the above C41. The priority of Group0 of all CSI reports is priority 0, which is the highest priority. Next, the priority of Group1 of CSI report 1 is 1, the priority of Group2 of CSI report 1 is 2,…, the priority of Group1 of CSI report Nrep is 2N_rep-1, and the priority of Group2 of CSI report Nrep is 2Nrep. The lower the priority value, the higher the priority. When discarding, the priority is from low to high (the priority value is from high to low), and when discarding the second part CSI information of a certain priority, the terminal needs to discard all the information of this priority value.

[0299] D12222. Divide the PMI first information field of the second part of all CSI reports into a group, and for each CSI report, divide the second part of the CSI into groups according to the first CRI to the Mth CRI. R The high-priority PMI second information domain associated with CRI, the Mth R +1 to Mth CRIs associated with the high-priority PMI second information domain, the first CRI to the Mth CRI R The low-priority PMI second information domain associated with each CRI, the Mth R The low-priority PMI second information domain associated with +1 CRI to M CRI is divided into four groups, and priority is assigned from smallest to largest according to the CSI report number and the group number corresponding to the CSI report.

[0300] It should be noted that, since the second part of CSI in Case 4 is further divided into PMI first information domain, high-priority PMI second information domain, and low-priority PMI second information domain, in this case, the PMI first information domains of all CSI reports are grouped together. The high-priority PMI second information domains and low-priority PMI second information domains of each CSI report are grouped according to the CRIs reported by the network device configured by the terminal and the CRIs selected by the terminal for reporting. The groups of each CSI report are uniformly numbered according to the CSI report number, and the priority of the PMI first information domain of the second part of CSI is higher than that of the high-priority PMI second information domain and the low-priority PMI second information domain.

[0301] It should be noted that when numbering groups, the priority of the group corresponding to the CRI reported by the network device configuration terminal can be configured to be higher than the priority of the group corresponding to the CRI selected and reported by the terminal, or the priority of the group corresponding to the CRI selected and reported by the terminal can be higher than the priority of the group corresponding to the CRI reported by the network device configuration terminal.

[0302] In some embodiments, the terminal may discard a portion of the second CSI, n=1,…,N rep CSI Part 2 of each CSI report is grouped according to C42 above. All CSI reports in Group 0 have a priority of 0, the highest priority. Next, CSI report 1's Group 1 has a priority of 1, CSI report 1's Group 2 has a priority of 2, CSI report 1's Group 3 has a priority of 3, CSI report 1's Group 4 has a priority of 4, ..., CSI report N... rep The priority of Group 1 is 4N. rep -3, CSI Report N reppriority of Group2 is 4N rep -2, CSI report N rep priority of Group3 is 4N rep -1, CSI report N rep priority of Group4 is 4N rep The lower the priority value, the higher the priority. When discarding, the discarding is performed in the order of priority from low to high (priority value from high to low), and when discarding a second part of CSI of a certain priority, the terminal needs to discard all the information of the priority value.

[0303] The group order in this case is: set all Group0 of all CSI reports as the highest priority priority0, and arrange the priorities in the order of Group1, Group2, Group3, and Group4 according to the CSI report index.

[0304] D12223, divide the PMI first information domain of the second part of CSI of all CSI reports into a group, divide the high priority PMI second information domain and the low priority PMI second information domain of the second part of CSI of each CSI report according to each CRI into 2M groups, and arrange the priorities in the order of small to large according to the CSI report number and the group number corresponding to the CSI report.

[0305] It should be noted that, because the second part of CSI in case 4 is divided into PMI first information domain, high priority PMI second information domain, and low priority PMI second information domain, in this case, the PMI first information domain of all CSI reports is divided into a group, the high priority PMI second information domain and the low priority PMI second information domain of each CSI report are divided into groups according to each CRI, and the group of each CSI report is numbered according to the CSI report number, and the priority of the PMI first information domain of the second part of CSI is higher than that of the high priority PMI second information domain and the low priority PMI second information domain.

[0306] It should be noted that, when numbering the groups, the priority of the group corresponding to the CRI reported by the terminal can be configured by the network device to be higher than the priority of the group corresponding to the CRI selected by the terminal for reporting, or the priority of the group corresponding to the CRI selected by the terminal for reporting can be higher than the priority of the group corresponding to the CRI reported by the terminal.

[0307] In some embodiments, the terminal can discard a part of the second part of CSI, n = 1, …, N repCSI part 2 of each CSI report is grouped according to the above C43. The priority of Group 0 of all CSI reports is priority 0, which is the highest priority. Next, the priority of Group 1 of CSI report 1 is 1, the priority of Group 2 of CSI report 1 is 2, …, the priority of Group M of CSI report 1 is M, the priority of Group M+1 of CSI report 1 is M+1, …, the priority of Group 2M of CSI report 1 is 2M, …, the priority of Group 1 of CSI report N rep rep rep rep The lower the priority value, the higher the priority. When dropping, the dropping is performed from low to high priority, and when dropping the second part of CSI of a certain priority, the UE needs to drop all the information of this priority.

[0308] The group order in this case is: set Group 0 of all CSI reports as the highest priority priority 0, and arrange the priorities in the order of Group 1, …, Group M, Group M+1, …, Group 2M according to the CSI report index.

[0309] The specific application of each of the above cases is illustrated as follows.

[0355] As shown in FIG. 3, the embodiment of the present disclosure provides an information transmission method, executed by a network device, comprising:

[0356] In step S301, according to the uplink control information (UCI) structure and the UCI mapping order corresponding to the multi-channel state information reference signal (CRI) report, the network device receives channel state information (CSI) report information corresponding to the multi-CRI report sent by the terminal device.

[0357] The multi-CRI report includes a plurality of report quantities associated with a plurality of CSI resources, and the report quantity includes at least one of the following:

[0358] CRI, RI, CQI, PMI, and LI.

[0359] It should be noted that, by receiving the CSI report information corresponding to the multi-CRI report sent by the terminal device based on the UCI structure and the UCI mapping order corresponding to the multi-CRI report, the embodiment of the present disclosure can realize the reception of the multi-CRI and improve the communication flexibility.

[0360] In some embodiments, in an implementation, the method further comprises:

[0361] The network device sends a configuration parameter to the terminal device, and the configuration parameter is used to indicate whether the terminal device needs to report a plurality of CRIs.

[0362] It should be noted that, by sending the configuration parameter to the terminal device, the network side can control the reporting of the plurality of CRIs, thereby ensuring the communication flexibility.

[0363] In some embodiments, the configuration parameter includes at least one of the following:

[0364] E11, CSI reporting type indication information, the CSI reporting type indication information is used to indicate whether multiple CRIs need to be reported;

[0365] It should be noted that this case is to indicate whether the CSI reporting type is multiple CRI reporting by using one indication information alone, for example, a bit can be used for indication, when the bit takes value 1, it represents multiple CRI reporting, when the bit takes value 0, it represents not multiple CRI reporting, i.e. single multiple CRI reporting; or, when the bit takes value 0, it represents multiple CRI reporting, when the bit takes value 1, it represents not multiple CRI reporting, i.e. single multiple CRI reporting.

[0366] E12, CSI reporting codebook type indication information, the CSI reporting codebook type indication information is used to indicate the codebook type of CSI reporting and whether multiple CRIs need to be reported based on the codebook type;

[0367] It should be noted that this case is to indicate multiple CRI reporting through codebook, because the structures of different codebooks are different, the structure of the codebook can reflect whether it is multiple CRI reporting, after the terminal receives the CSI reporting codebook type indication information, it can not only determine which codebook is used for reporting, but also determine whether it is multiple CRI reporting.

[0368] For example, the codebook type can include the multiple CRI type of Type I single panel codebook or the multiple CRI type of eType II.

[0369] E13, CRI number indication information, the CRI number indication information is used to indicate the number of reported CRIs;

[0370] In some embodiments, this case is to indicate the number of CRI reporting, usually the number of CRIs indicated by the CRI number indication information is greater than or equal to 2.

[0371] In some embodiments, in one implementation, in the case of configuring parameters to indicate that multiple CRIs need to be reported, the CRI number indication information usually needs to be included in the configuration parameters; of course, the CRI number indication information can also be used to indicate multiple CRI reporting implicitly, therefore, the configuration parameters can only include item A13.
