[0174] In some embodiments of the present disclosure, the Channel Status Information (CSI) reporting setting may include the configuration of the following parameters: CSI reporting quantity, codebook configuration, time domain characteristics of CSI feedback, frequency domain granularity of PMI and CQI, etc. The reporting quantity based on CRI may include: CRI-RI-PMI-CQI, CRI-RI-LI (Layer Indicator)-PMI-CQI, CRI-RI-CQI, CRI-RSRP (Reference Signal Receiving Power, Reference Signal Received Power), etc. Among them, the configured reporting quantity is CRI-RI-PMI-CQI, which means that CRI, RI, PMI and CQI are fed back together. The protocol supports network-side configuration of K s (K s >1) CSI-RS resources are used for channel measurement, when K s =2, each CSI-RS resource can include up to 16 ports. s When ≤8, each CSI-RS resource can include up to 8 ports. The CRI is reported to indicate the selected CSI-RS resource. The UE determines the corresponding RI, PMI, CQI and other indication information based on the CSI-RS resource and reports it to the network side.

[0175] For the Rel-15 Type I single-panel codebook, the bit widths of the RI, LI, CQI, and CRI indication information are shown in Table 1, where n RI It indicates the rank that the network allows to report, and υ indicates the maximum rank that the terminal can report.

[0182] Table 4

[0183] In some embodiments, increasing the number of antenna ports to expand the antenna scale is a key technical approach to further improve system efficiency or enhance coverage. In current commercial deployments, the antenna scale can be quadrupled. For example, support for 64 or 128 CSI-RS ports is required to enable channel measurement for these 64 or 128 antenna ports. Considering the trade-off between performance and deployment cost, hybrid digital and analog beamforming will continue to be used in future standard evolution. With a larger number of ports, the number of users connected to the network also increases. Consequently, the network requires terminals to provide feedback on more CRIs, RIs, CQIs, and / or PMIs for multi-user scheduling and improved system performance. Each RI / CQI / PMI is calculated based on an independent CSI-RS resource, and the corresponding CSI-RS resource is indicated by the CRI. When CRI is greater than 1, independently reporting the corresponding RI / CQI / PMI for each resource will exponentially increase feedback overhead. Therefore, reducing terminal feedback overhead while ensuring limited performance loss is a pressing issue.

[0184] FIG2 is an interactive diagram illustrating an information reporting method according to an embodiment of the present disclosure. The method may be executed by the above-mentioned communication system. As shown in FIG2 , the method may include:

[0185] Step S2101: The network device sends first information of the network device configuration to the terminal device.

[0186] In some embodiments, the terminal device may receive the first information. For example, the terminal device may receive the first information sent by a network device. For another example, the terminal device may also receive the first information sent by another entity.

[0187] In some embodiments, the first information may include multiple CSI-RS resources.

[0188] In some embodiments, the first information can be configured in a manner specified by the protocol, which will not be described in detail here.

[0189] In some embodiments, the name of the first information is not limited, and may be, for example, "CSI-RS resource configuration", "CSI-RS resource configuration indication information", "measurement configuration indication information", etc.

[0190] Step S2102: The terminal device performs measurements based on multiple CSI-RS resources to obtain multiple measurement results.

[0191] In some embodiments, the terminal device may perform measurements based on multiple CSI-RS resources in a manner specified by the protocol to obtain multiple measurement results, which will not be described in detail here.

[0192] In some embodiments, different CSI-RS resources may correspond to different measurement results. For example, each CSI-RS resource corresponds to one measurement result.

[0193] Step S2103: The terminal device reports the second information to the network device.

[0194] In some embodiments, the second information may be used to indicate multiple measurement results.

[0195] In some embodiments, the second information may include first indication information, where the first indication information is used to indicate a first CSI-RS resource, and the first CSI-RS resource may include a first number of CSI-RS resources among multiple CSI-RS resources.

[0196] In some embodiments, the first indication information may also be referred to as CRI.

[0197] In some embodiments, the terminal device may select a first number of CSI-RS resources from a plurality of CSI-RS resources configured by the network device as the first CSI-RS resource. For example, if the first number is M, the terminal device may select M CSI-RS resources from the plurality of CSI-RS resources as the first CSI-RS resource.

[0198] In some embodiments, the second information may further include second indication information, and the second indication information may be used to indicate the first quantity.

[0199] For example, when the terminal device determines the first CSI-RS resource by itself, the number of CSI-RS resources included in the first CSI-RS resource, that is, the first number, can be reported to the network device.

[0200] In some embodiments, the bit width of the second indication information may be Among them, K s is the number of multiple CSI-RS resources.

[0201] In some embodiments, the unit of the bit width may be bits.

[0202] In some embodiments, the bit width may be understood as the number of bits occupied. For example, the bit width of the second indication information may be the number of bits occupied by the second indication information.

[0203] For example, if the number of CSI-RS resources configured by the network device is K s is 4, then the bit width of the second indication information is 2 bits.

[0204] In some embodiments, the terminal device may receive third information sent by the network device, and the third information may be used to indicate the first quantity.

[0205] For example, after receiving the third information sent by the network device, the terminal device can determine the first CSI-RS resource according to the first quantity indicated by the third information.

[0206] In some embodiments, the bit width of the first indication information may be K s , where K s is the number of multiple CSI-RS resources.

[0207] For example, if the first information includes 4 CSI-RS resources, namely K s =4, the IDs of the four CSI-RS resources are 1, 2, 3, and 4 respectively, then the bit width of the first indication information is 4 bits, and the terminal device can indicate the reported CRI through the bit width of 4 bits, as shown in Table 5.

[0208] Table 5

[0209] Among them, 1 indicates that the RI / PMI / CQI corresponding to the CSI-RS resource is reported, and 0 indicates that the RI / PMI / CQI corresponding to the CSI-RS resource is not reported. The indication of the bitmap can be sorted in order according to the ID of the CSI-RS resource from small to large or from large to small, such as the least significant bit (LSB) in the bitmap in Table 5 corresponds to CSI-RS ID1, and the most significant bit (MSB) in the bitmap corresponds to CSI-RS ID4. Therefore, according to the indication of the bitmap, it can be seen that the terminal device only reports the RI / PMI / CQI of the CSI-RS resources corresponding to CSI-RS ID2 and CSI-RS ID3.

[0210] In some embodiments, the bit width of the first indication information may be Among them, K s is the number of multiple CSI-RS resources, and M is the first number.

[0211] in, Indicates K configured from the network device sA binomial calculation is performed to select M CSI-RS resources from among the CSI-RS resources.

[0212] In some embodiments, the second information may include third indication information, and the third indication information may be used to indicate the rank indication RI corresponding to the first CSI-RS resource.

[0213] In one implementation, for all CSI-RS resources in the first CSI-RS resource, only one RI is reported, and the third indication information may be used to indicate the RI.

[0214] In some embodiments, the bit width of the third indication information can be determined according to a second number, where the second number is the number of layers that the network device is allowed to report.

[0215] In one implementation, the bit width of the third indication information may be any one of the following: Among them, n RI is the second quantity.

[0216] For example, if the third indication information includes one RI, that is, for all CSI-RS resources in the first CSI-RS resource, only one RI is reported, then the bit width of the third indication information can be

[0217] In some embodiments, the first indication information may include multiple fourth indication information, and different fourth indication information is used to indicate the RI corresponding to different CSI-RS resources in the first CSI-RS resource.

[0218] In some embodiments, "different fourth indication information is used to indicate the RIs corresponding to different CSI-RS resources in the first CSI-RS resource" can be understood as "each CSI-RS resource in the first CSI-RS resource corresponds to an RI, and each fourth indication information indicates an RI."

[0219] For example, for each CSI-RS resource in the first CSI-RS resources, the RI corresponding to each CSI-RS resource may be indicated respectively, that is, one RI is reported for each CSI-RS resource.

[0220] The bit width of the fourth indication information may be determined by referring to the method for determining the bit width of the third indication information, which will not be described in detail here.

[0221] In some embodiments, the first indication information may include fifth indication information, where the fifth indication information is used to indicate a combination index of a first RI combination, where the first RI combination is a combination of RIs corresponding to the first CSI-RS resource.

[0222] For example, if the first CSI-RS resource includes two CSI-RS resources, and the maximum RI corresponding to the two CSI-RS resources is 2, it can be determined that the first RI corresponding to the two CSI-RS resources both include 1 and 2, and the second RI combination can include (1,1), (1,2), (2,1) and (2,2), among which (1,1) indicates that the RI of the two CSI-RS resources is 1, (1,2) indicates that the RI of the first CSI-RS resource is 1, and the RI of the second CSI-RS resource is 2. The explanations of other combinations are similar and will not be repeated here.

[0223] In some embodiments, each second RI combination may correspond to a combination index. Taking the above-mentioned four second RI combinations as an example, the combination indexes may include 1, 2, 3, and 4.

[0224] For example, if the first RI combination is (1, 2), the combination index of the first RI is 2, and the fifth indication information may indicate the combination index 2.

[0225] In some embodiments, the bit width of the fifth indication information can be determined based on the number of second RI combinations, where the second RI combination includes a combination of first RIs corresponding to the first CSI-RS resource, and the first RI includes an RI that is less than or equal to the maximum RI corresponding to the first CSI-RS resource.

[0226] In one implementation, the bit width of the fifth indication information may be Taking the above-mentioned 4 second RI combinations as an example, the number of the second RI combinations is 4, and the bit width of the fifth indication information is 2 bits.

[0227] In some embodiments, the second information may include sixth indication information, where the sixth indication information is used to indicate a layer indication LI corresponding to the first CSI-RS resource.

[0228] In some embodiments, for all CSI-RS resources in the first CSI-RS resource, only one LI is reported, and the sixth indication information can be used to indicate the RI.

[0229] In some embodiments, the bit width of the sixth indication information is determined based on a third number, where the third number is the number of layers that the terminal device can report.

[0230] In one implementation, the bit width of the sixth indication information may be or Here, υ is the third quantity.

[0231] For example, if the sixth indication information includes one LI, that is, for all CSI-RS resources in the first CSI-RS resource, only one LI is reported, then the bit width of the sixth indication information can be

[0232] In some embodiments, the second information may include seventh indication information, where the seventh indication information is used to indicate a channel quality indicator CQI corresponding to the first CSI-RS resource.

[0233] In some embodiments, the CQI may include a wideband CQI and a subband CQI.

[0234] In some embodiments, for each CSI-RS resource in the first CSI-RS resources, a wideband CQI may be independently reported.

[0235] In some embodiments, the seventh indication information may include multiple eighth indication information, and different eighth indication information may be used to indicate the wideband CQI corresponding to different CSI-RS resources.

[0236] For example, for each CSI-RS resource in the first CSI-RS resources, the wideband CQI corresponding to each CSI-RS resource may be indicated respectively, that is, each CSI-RS resource reports a wideband CQI.

[0237] In some embodiments, the seventh indication information may include ninth indication information and tenth indication information, the ninth indication information may be used to indicate a reference wideband CQI, the tenth indication information may be used to indicate a first differential component, the first differential component may include a differential component between the second wideband CQI corresponding to each CSI-RS resource in the second CSI-RS resource and the reference wideband CQI, or a differential component between the second wideband CQI corresponding to each CSI-RS resource in the first CSI-RS resource and the reference wideband CQI, the second CSI-RS resource including the CSI-RS resources in the first CSI-RS resource excluding the reference CSI-RS resources.

[0238] In some embodiments, the reference wideband CQI may be any of the following:

[0239] Refer to the wideband CQI corresponding to the CSI-RS resource;

[0240] an average value of second wideband CQIs corresponding to multiple CSI-RS resources in the first CSI-RS resource.

[0241] In one implementation, a reference CSI-RS resource may be determined from the first CSI-RS resource, and the wideband CQI corresponding to the reference CSI-RS resource may be used as the reference wideband CQI.

[0242] In another implementation, the second wideband CQI corresponding to each CSI-RS resource in the first CSI-RS resource may be determined to obtain multiple second wideband CQIs, and an average value of the multiple second wideband CQIs may be determined, and the average value may be used as the reference wideband CQI.

[0243] In some embodiments, if the reference wideband CQI is the wideband CQI corresponding to the reference CSI-RS resource, the first difference component may include the difference component between the second wideband CQI corresponding to each CSI-RS resource in the second CSI-RS resource and the reference wideband CQI.

[0244] In some embodiments, if the reference wideband CQI is the average value of the second wideband CQIs corresponding to multiple CSI-RS resources in the first CSI-RS resource, then the first difference component may include the difference component between the second wideband CQI corresponding to each CSI-RS resource in the first CSI-RS resource and the reference wideband CQI.

[0245] In some embodiments, the reference CSI-RS resource may be determined according to a first rule, where the first rule is a protocol agreement or a network device instruction.

[0246] Here, "protocol agreement" can be understood as "predefined", for example, the predefined reference CSI-RS resource can be the CSI-RS resource corresponding to the first CRI in the reported CRI.

[0247] It should be noted that the reference CSI-RS resource may also be other predefined CSI-RS resources, which is not limited in the embodiments of the present disclosure.

[0248] Here, “network device indication” can be understood as the network device indicating a CSI-RS resource as the reference CSI-RS resource.

[0249] In some embodiments, the first differential component may include multiple differential components, and different differential components correspond to different CSI-RS resources.

[0250] In some embodiments, “different differential amounts correspond to different CSI-RS resources” can be understood as “each CSI-RS resource corresponds to one differential amount”.

[0251] In one implementation, the terminal device can determine the reference CSI-RS resource from the first CSI-RS resource, and determine the second broadband CQI corresponding to each CSI-RS resource in the first CSI-RS resource. For example, if the first CSI-RS resource includes CSI-RS resource 1, CSI-RS resource 2, CSI-RS resource 2, and CSI-RS resource 4, and CSI-RS resource 1 is the reference CSI-RS resource, then the second broadband CQIs corresponding to the four CSI-RS resources can be determined respectively, and the second broadband CQI corresponding to CSI-RS resource 1 is the reference broadband CQI. Afterwards, the difference between the second broadband CQI corresponding to CSI-RS resource 2 and the reference broadband CQI, the difference between the second broadband CQI corresponding to CSI-RS resource 3 and the reference broadband CQI, and the difference between the second broadband CQI corresponding to CSI-RS resource 4 and the reference broadband CQI can be determined, and the two difference components obtained are the first difference components.

[0252] For example, the terminal device reports the CQI corresponding to two CRIs, that is, the first CSI-RS resource includes two CSI-RS resources, and the wideband CQI corresponding to the CSI-RS resource with the smallest ID in the first CSI-RS resource is predefined as the reference wideband CQI, which can be quantized by a=4 bits. The other CSI-RS resource in the first CSI-RS resource can be differentially quantized by 2 bits.

[0253] In one implementation, the tenth indication information may also be differential CQI indication information, with different differential CQI indication information corresponding to different differential values, i.e., each differential CQI indication information corresponds to a differential value. As shown in Table 6, if the value indicated by the differential CQI indication information is 0, the differential value is also 0; if the value indicated by the differential CQI indication information is 1, the differential value is also 1; if the value indicated by the differential CQI indication information is 2, the differential value is ≥ 2, for example, the differential value may be 4; if the value indicated by the differential CQI indication information is 3, the differential value is ≤ -1, for example, the differential value may be -2.

[0254] It should be noted that the above-mentioned difference value ≥ 2 means that the difference value can be any value greater than or equal to 2, and the difference value ≤ -1 means that the difference value can be any value less than or equal to -1, which can be agreed upon through the protocol, and the embodiments of the present disclosure do not limit this.

[0255] Table 6

[0256] Taking Table 6 as an example, if the first difference value is 1 and the reference wideband CQI is 8, then the wideband CQI corresponding to another CSI-RS resource in the first CSI-RS resource is 9.

[0257] The above-mentioned method of reporting the differential amount through differential CQI indication information can reduce the amount of data reported by the terminal device, thereby further reducing the feedback overhead of the terminal device.

[0258] In some embodiments, the second information may further include eleventh indication information, which may be used to indicate a second differential value, and the second differential value may be a differential value between the subband CQI and the wideband CQI corresponding to each CSI-RS resource.

[0259] For example, for each CSI-RS resource in the first CSI-RS resource, the wideband CQI and subband CQI corresponding to the CSI-RS resource can be determined respectively, and the difference between the subband CQI and the wideband CQI can be calculated to obtain the second difference.

[0260] It should be noted that, for the description of the second difference amount, reference can be made to the above description of the first difference amount, which will not be repeated here.

[0261] In some embodiments, the second information may include twelfth indication information, and the twelfth indication information may be used to indicate the number of non-zero coefficients of multiple data transmission layers corresponding to the first CSI-RS resource.

[0262] In some embodiments, the twelfth indication information may indicate the number of non-zero wideband amplitude coefficients in the Rel-15 Type II codebook.

[0263] In some embodiments, for each data transmission layer, the number of non-zero coefficients corresponding to each CSI-RS resource in the first CSI-RS resource may be reported separately.

[0264] In some embodiments, the twelfth indication information may include multiple thirteenth indication information, and different thirteenth indication information may be used to indicate the number of non-zero coefficients of different data transmission layers corresponding to different CSI-RS resources.

[0265] For example, for each data transmission layer, the number of non-zero coefficients corresponding to each CSI-RS resource can be indicated separately, that is, the number of non-zero coefficients is reported for each CSI-RS resource. If the number of data transmission layers is 2, and the first CSI-RS resource includes two CSI-RS resources, then for the first data transmission layer, the number of non-zero coefficients corresponding to the two CSI-RS resources can be reported separately, and for the second data transmission layer, the number of non-zero coefficients corresponding to the two CSI-RS resources can also be reported separately.

[0266] In some embodiments, the twelfth indication information includes fourteenth indication information and fifteenth indication information, the fourteenth indication information is used to indicate the first reference number corresponding to each data transmission layer, and the fifteenth indication information is used to indicate the difference between the number of non-zero coefficients of each data transmission layer corresponding to each CSI-RS resource in the first CSI-RS resource and the first reference number corresponding to the data transmission layer.

[0267] In some embodiments, the first reference number can be determined by:

[0268] Determine the number of non-zero coefficients of the data transmission layer corresponding to each CSI-RS resource in the first CSI-RS resource to obtain multiple first numbers;

[0269] The first reference number is determined based on a plurality of first numbers.

[0270] It should be noted that the above method for determining the first reference number is for a data transmission layer, and for each data transmission layer, the first reference number corresponding to the data transmission layer can be determined in the above manner.

[0271] In some embodiments, determining the first reference number based on the plurality of first numbers includes any one of the following:

[0272] Taking the maximum value among the plurality of first numbers as the first reference number;

[0273] Taking the minimum value among the plurality of first numbers as the first reference number;

[0274] An average value among the plurality of first numbers is taken as the first reference number.

[0275] For example, for each data transmission layer, the number of non-zero coefficients of the data transmission layer corresponding to each CSI-RS resource in the first CSI-RS resource can be determined to obtain multiple first numbers, and the maximum value of the multiple first numbers is used as the first reference number corresponding to the data transmission layer. The difference between each first number and the first reference number can then be determined.

[0276] If the number of data transmission layers is 2, and the first CSI-RS resource includes CSI-RS resource 1 and CSI-RS resource 2, then for the first data transmission layer, the first number of non-zero coefficients of the first data transmission layer corresponding to CSI-RS resource 1 and the first number of non-zero coefficients of the first data transmission layer corresponding to CSI-RS resource 2 can be determined. If the first number corresponding to CSI-RS resource 1 is determined to be the maximum value, the first number corresponding to CSI-RS resource 1 is used as the first reference number. Thereafter, the difference between the first number corresponding to CSI-RS resource 2 and the first reference number can be determined. For the second data transmission layer, another difference can be determined using the same method as above.

[0280] In one implementation, if the first reference number is the maximum value or the minimum value among multiple first numbers, the CSI-RS resources corresponding to the first reference number may be reported to the network device.

[0281] It should be noted that if the first reference number is an average of multiple first numbers, the CSI-RS resources corresponding to the first reference number may not be reported to the network device, that is, the second information may not include the sixteenth indication information.

[0282] In some embodiments, the bit width of the sixteenth indication information is determined according to the number of multiple CSI-RS resources.

[0283] In one implementation, the bit width of the sixteenth indication information may be

[0284] In some embodiments, the second signal may include multiple seventeenth indication information, and different seventeenth indication information may be used to indicate the number of non-zero coefficients of all data transmission layers corresponding to different CSI-RS resources.

[0285] In some embodiments, the seventeenth indication information may indicate the number of non-zero coefficients in the Rel-16 / 17 Type II codebook.

[0286] In some embodiments, “the number of non-zero coefficients in all data transmission layers” may be understood as “the sum of the numbers of non-zero coefficients in multiple data transmission layers”.

[0287] For example, if the number of data transmission layers is 2, and the first CSI-RS resource includes CSI-RS resource 1 and CSI-RS resource 2, then for CSI-RS resource 1, the number of non-zero coefficients of the first data transmission layer corresponding to CSI-RS resource 1 and the number of non-zero coefficients of the second data transmission layer corresponding to CSI-RS resource 1 can be determined, and the sum of the two numbers is used as the number of non-zero coefficients of all data transmission layers corresponding to CSI-RS resource 1.

[0297] For example, for each CSI-RS resource in the first CSI-RS resource, a first number of non-zero coefficients for each data transmission layer corresponding to the CSI-RS resource can be determined, and the sum of multiple first numbers is used as the second number of non-zero coefficients for all data transmission layers corresponding to the CSI-RS resource to obtain multiple second numbers. The maximum value of the multiple second numbers is used as the second reference number. Thereafter, the difference between each second number and the second reference number can be determined.

[0298] If the number of data transmission layers is 2, and the first CSI-RS resource includes CSI-RS resource 1 and CSI-RS resource 2, then for CSI-RS resource 1, the first number of non-zero coefficients of the first data transmission layer corresponding to CSI-RS resource 1 and the first number of non-zero coefficients of the second data transmission layer corresponding to CSI-RS resource 1 can be determined, and the sum of the two first numbers can be determined to obtain the second number of non-zero coefficients of all data transmission layers corresponding to CSI-RS resource 1. The second number of non-zero coefficients of all data transmission layers corresponding to CSI-RS resource 2 can be determined using the same method as described above. If the second reference number is the minimum value of multiple second numbers, and the second number of non-zero coefficients of all data transmission layers corresponding to CSI-RS resource 1 is greater than the second number of non-zero coefficients of all data transmission layers corresponding to CSI-RS resource 2, the second number of non-zero coefficients of all data transmission layers corresponding to CSI-RS resource 2 can be used as the second reference number. Subsequently, the difference between the second number of non-zero coefficients of all data transmission layers corresponding to CSI-RS resource 1 and the second reference number can be determined.

[0299] In some embodiments, the bit widths of the eighteenth indication information and the nineteenth indication information are determined according to the maximum number of non-zero coefficients allowed by all data transmission layers corresponding to the first CSI-RS resource.

[0300] In one implementation, the bit width of the eighteenth indication information may be or The bit width of the nineteenth indication information may be or K0 is the maximum number of non-zero coefficients allowed in all data transmission layers corresponding to the first CSI-RS resource.

[0302] In one implementation, if the second reference number is the maximum value or the minimum value among multiple second numbers, the CSI-RS resources corresponding to the second reference number may be reported to the network device.

[0303] It should be noted that if the second reference number is an average of multiple second numbers, the CSI-RS resources corresponding to the second reference number may not be reported to the network device, that is, the second information may not include the twentieth indication information.

[0304] In some embodiments, the bit width of the twentieth indication information is determined according to the number of the plurality of CSI-RS resources.

[0447] Option 2-1: The number of non-zero coefficients of all layers corresponding to each CSI-RS resource is indicated and reported separately.

[0448] Option 2-2: Pass or Indicates a minimum, maximum or average value corresponding to the number of non-zero coefficients of all layers, and then indicates the difference between the minimum, maximum or average value through Y bits. Y can be or If the X bits indicate the minimum or maximum value, you also need Indicates which resource corresponds to the maximum or minimum number of non-zero wideband coefficients.

[0449] Example 1:

[0450] Assume that the gNB configures K for the UE s =4 CSI-RS resources, with CSI-RS resource IDs 1, 2, 3, and 4, respectively. If the Option 1 method described above is used, the UE can indicate this through the following 4-bit bitmap, as shown in Table 5. 1 in Table 5 indicates that the RI / PMI / CQI corresponding to the resource is reported; otherwise, the RI / PMI / CQI corresponding to the resource is not reported. The bitmap indications in Table 5 correspond in sequence based on the order of the CSI-RS resource IDs, from small to large or from large to small. For example, the lowest bit in the bitmap corresponds to CSI-RS ID1, and the highest bit in the bitmap corresponds to CSI-RS ID4. Therefore, according to this bitmap indication, the terminal only reports the RI / PMI / CQI corresponding to CSI-RS ID2 and CSI-RS ID3.

[0451] Example 2: Assuming that the UE reports CQIs corresponding to two CRIs, the wideband CQI corresponding to the CSI-RS with the smallest predefined CSI-RS resource ID is used as the reference wideband CQI and is quantized using a = 4 bits. The wideband CQI corresponding to the other resource is differentially quantized using 2 bits. The differential quantization table is shown in Table 6. If the value of the wideband differential quantization indicator is 1 and the value of the reference wideband quantization indicator is 8, the value of the other wideband CQI is 9. The subband differential CQI corresponding to a resource is calculated based on the value of the differential quantization indicator and the value of the corresponding wideband CQI indicator, using a calculation method similar to the wideband differential quantization calculation method described above.

[0452] Example 3:

[0453] Assume that the gNB configures K for the UE s =4 CSI-RS resources.

[0454] For the reporting of the number of non-zero coefficients in the Rel-15 Type II codebook, let the number of spatial basis vectors configured by the gNB for the UE be L = 4. It is still assumed that the terminal reports the number of non-zero wideband coefficients corresponding to two CRIs, and the RI corresponding to each CRI is 1, that is, both are used for one-layer data transmission. The number of non-zero coefficients corresponding to these two CRIs is 4 and 6 respectively, and the predefined minimum value is Indicates that its value is 4, and then the UE also passes Indicates which resource has the smallest number of broadband non-zero coefficients. The number of non-zero broadband coefficients corresponding to the other CRI is calculated by The difference between the two is 2, and the number of non-zero coefficients can be calculated to be 4+2=6.

[0455] For reporting the number of non-zero coefficients in Rel-16 or 17 Type II codebooks, the non-zero coefficient indication reporting method is similar to the above-mentioned method for indicating the number of non-zero coefficients per layer of the wideband Rel-15 Type II codebook.
