Field of Technology

[0002] Wireless communication technology is a key component of an increasingly interconnected global communication network. Wireless communication relies on accurately allocated time and frequency resources to transmit and receive wireless signals. To achieve better communication performance, a network node, such as a User Equipment (UE), may measure the channel state, and the measurement report may be reported to a Base Station (BS). How to efficiently report the channel state is an issue for reducing channel monitoring overhead. Summary of the Invention

[0024] Figure 1 A block diagram of an exemplary wireless communication system 10 according to some embodiments of the present disclosure is shown. The system 10 may execute the methods / steps and their combinations disclosed in the present disclosure. The system 10 may include components and elements configured to support operational features not detailed herein.

[0025] The system 10 may include a Base Station (BS) 110 and a User Equipment (UE) 120. The BS 110 includes a BS transceiver or transceiver module 112, a BS antenna system 116, a BS memory or memory module 114, a BS processor or processor module 113, and a network interface 111. The components of the BS 110 may be electrically coupled and communicate with each other via a data communication bus 180 as needed. Similarly, the UE 120 includes a UE transceiver or transceiver module 122, a UE antenna system 126, a UE memory or memory module 124, a UE processor or processor module 123, and an I / O interface 121. The components of the UE 120 may be electrically coupled and communicate with each other via a data communication bus 190 as needed. The BS 110 communicates with the UE 120 via a communication channel therebetween, which may be any wireless channel or other medium known in the art suitable for transmitting the data described herein.

[0026] The processor modules 113, 123 may be implemented or realized using a general-purpose processor, a content addressable memory, a digital signal processor, an application specific integrated circuit, a field programmable gate array, any suitable programmable logic device, discrete gate or transistor logic, discrete hardware components, or any combination thereof, and are designed to perform the functions described herein. In this way, the processor modules may be implemented as a microprocessor, a controller, a microcontroller, or a state machine, etc. The processor modules may also be implemented as a combination of computing devices, such as a combination of a digital signal processor and a microprocessor, multiple microprocessors, one or more microprocessors combined with a digital signal processor core, or any other such configuration.

[0027] In addition, the steps of the methods or algorithms described in connection with the embodiments disclosed herein may be embodied directly in hardware, firmware, software modules executed respectively by processor modules 113 and 123, or in any actual combination thereof. Memory modules 113 and 123 may be implemented as RAM memory, flash memory, EEPROM memory, registers, ROM memory, EPROM memory, hard disk, removable disk, CD-ROM, or any other form of storage medium known in the art. In this regard, memory modules 114 and 124 may be coupled to processor modules 113 and 123 respectively, such that processor modules 113 and 123 may read information from and write information to memory modules 114 and 124 respectively. Memory modules 114 and 124 may also be integrated into their respective processor modules 113 and 123. In some embodiments, memory modules 114 and 124 may each include: a cache memory for storing temporary variables or other intermediate information during the execution of instructions executed respectively by processor modules 113 and 123. Memory modules 114 and 124 may also each include: a non-volatile memory for storing instructions executed respectively by processor modules 113 and 123.

[0028] In the related art, the UE is configured with at least one resource setting for channel measurement and at least one report setting for CSI reporting. For example, the BS may send an RRC message or other control signal to control what information the UE needs to report to the BS. Each report setting contains parameters for one CSI reporting band and CSI-related quantities that the UE is to report. For beam management, the CSI-related quantities that the UE is to report may be indicated by the higher layer parameter reportQuantity in the report setting, and the higher layer parameters mainly include CSI-RS resource indicator (CRI), SS / PBCH block resource indicator (SSBRI), layer 1-reference signal receiving power (L1-RSRP), or layer 1-signal to interference plus noise ratio (L1-SINR).

[0029] More specifically, the higher layer parameter reportQuantity can be set to 'cri-RSRP', 'cri-SINR','ssb-Index-RSRP', and'ssb-Index-SINR'. For example, if the higher layer parameter reportQuantity is set to 'cri-RSRP', for each reporting setting, the UE can report one or more CRIs and the associated L1-RSRP in a single report, where the number of RS resources to be reported is configured by the higher layer.

[0030] For L1-SINR reporting, if the number of reference signal (RS) resources to be reported for each reporting setting is configured to 1, the reported L1-SINR value is defined by a 7-bit value in the range of [-23, 40] dB with a step size of 0.5 dB. If the number of measurement RS resources to be reported for each reporting setting is configured to be greater than 1, the UE can use differential L1-SINR-based reporting, where the maximum measured value of L1-SINR is quantized to a 7-bit value in the range of [-23, 40] dB with a step size of 0.5 dB. The differential L1-SINR is quantized to a 4-bit value. Referencing the maximum measured L1-SINR value as part of the same L1-SINR reporting instance, this differential L1-SINR value is calculated with a step size of 1 dB.

[0031] For L1-RSRP reporting, if the number of RS resources to be reported for each reporting setting is configured to 1, the reported L1-RSRP value can be defined by a 7-bit value in the range of [-140, -44] dBm with a step size of 1 dB. If the number of measurement RS resources to be reported for each reporting setting is configured to be greater than 1, the UE can use differential L1-RSRP-based reporting, where the maximum measured value of L1-RSRP is quantized to a 7-bit value in the range of [-140, -44] dBm with a step size of 1 dB. The differential L1-RSRP is quantized to a 4-bit value and, referencing the maximum measured L1-RSRP value as part of the same L1-RSRP reporting instance, this differential L1-RSRP value is calculated with a step size of 2 dB. The mapping of the measured quantity is defined as an example in the following table.

[0036] With the development of advanced algorithms and functional modules, more channel state information related quantities can be obtained at the UE side for reporting and beam selection. For example, the UE can provide the probability or confidence associated with the strongest RSRP for a corresponding resource indicator. Additionally, other information obtained by the UE can be used to predict or estimate the RSRP or SINR. For example, the UE can measure only a few RSRP or SINR (measured RSRP or SINR) and use these measurements to estimate or predict the RSRP or SINR of other channels or beams (predicted RSRP or SINR). Thus, different types of RSRP or SINR can be provided. According to some embodiments, the predicted RSRP or SINR can be a first type of RSRP or SINR, while the measured RSRP or SINR can be a second type, and vice versa.

[0037] According to some embodiments of the present disclosure, a wireless communication method is provided. The method includes: receiving, by a first wireless communication node, a reporting configuration from a second communication node; and reporting, by the first wireless communication node according to the reporting configuration, at least one of the following: CSI reference signal resource indicators (CRI); SS / PBCH block resource indicators (SSBRI); reference signal receiving power (RSRP) / signal to interference plus noise ratio (SINR) reporting values corresponding to the predicted or measured RSRP / SINR of the CRI or SSBRI; or multiple confidence / probability information corresponding to the confidence / probability values of one or more CRI or SSBRI, where: the reporting is performed in a reporting order based on the predicted RSRP / SINR corresponding to the CRI or SSBRI; the reporting is performed in a reporting order based on the multiple confidence / probability information corresponding to the CRI or SSBRI; or the reporting includes providing a location indicator for identifying one of the reported CRI, SSBRI, RSRP / SINR reporting values, or multiple confidence / probability information.

[0038] According to some embodiments of the present disclosure, another wireless communication method is provided. The method includes: sending a reporting configuration from a second wireless communication node to a first communication node; and receiving, by the second wireless communication node according to the reporting configuration, at least one of the following: CSI Reference Signal Resource Indicators (CRI); SS / PBCH Block Resource Indicators (SSBRI); an RSRP / SINR reporting value corresponding to a predicted or measured RSRP / SINR of the CRI or SSBRI; or multiple confidence / probability information corresponding to confidence / probability values of one or more CRIs or SSBRIs, where: the reporting is performed in a reporting order based on a predicted RSRP / SINR corresponding to the CRI or SSBRI; the reporting is performed in a reporting order based on multiple confidence / probability information corresponding to the CRI or SSBRI; or the reporting includes receiving a position indicator identifying one of the reported CRI, SSBRI, RSRP / SINR reporting value, or multiple confidence / probability information.

[0039] According to some embodiments, the reporting order presents the CRI or SSBRI in descending order based on a predicted RSRP / SINR or one or more corresponding confidence values corresponding to the CRI or SSBRI.

[0040] According to some embodiments, the reporting order presents the RSRP reporting value in descending order based on one or more corresponding predicted RSRP / SINRs.

[0041] According to some embodiments, the reporting order presents multiple confidence / probability information in descending order based on the confidence / probability value.

[0042] According to some embodiments, the method further includes determining whether a predicted RSRP / SINR corresponding to a candidate CRI is less than a threshold; and if the predicted RSRP / SINR corresponding to the candidate CRI is less than the threshold, determining not to report the predicted RSRP / SINR of the candidate CRI.

[0043] According to some embodiments, the method further includes determining whether confidence / probability information corresponding to a candidate CRI is less than a threshold; and if the confidence / probability information corresponding to the candidate CRI is less than the threshold, determining not to report the confidence / probability information of the candidate CRI.

[0044] CRI / SSBRI and / or RSRP / SINR Reporting Method

[0045] The following explanation takes CRI and RSRP as examples. However, it should be noted that in the following, CRI can be replaced by SSBRI, and RSRP can be replaced by SINR to achieve channel monitoring and reporting. Examples of such replacements will not be repeated in the specification.

[0046] According to some embodiments of the present disclosure, the CSI-related quantities that the UE needs to report may include CRI and L1-RSRP, or only include L1-RSRP. The L1-RSRP to be reported by the UE can be obtained through the UE's measurement or through the inference of a functional module (such as an artificial intelligence or machine learning model or function) deployed at the UE. The functional module can infer the predicted L1-RSRP for each CRI. For each CRI to be reported, if possible, the relevant L1-RSRP (i.e., the measured L1-RSRP) can be obtained through UE measurement. Otherwise, the relevant L1-RSRP to be reported (i.e., the predicted L1-RSRP) can be obtained through the inference of the functional module. According to some embodiments of the present disclosure, when both the measured L1-RSRP and the corresponding predicted L1-RSRP exist, the UE can preferably report the measured L1-RSRP of the CRI.

[0047] For L1-RSRP reporting, the network can configure and indicate more than two L1-RSRP reporting methods with different quantization bits and / or step sizes, such as traditional methods and the following enhanced L1-RSRP reporting methods.

[0048] According to some embodiments of the present disclosure, the UE can be configured with a threshold for predicted L1-RSRP reporting. Predicted L1-RSRP below the threshold is not expected to be reported by the UE to the BS. Alternatively, for predicted L1-RSRP below or equal to the threshold, it is not expected to be reported by the UE to the BS.

[0049] According to some embodiments of the present disclosure regarding the mapping order of a reported CSI field, the CRI associated with the maximum predicted L1-RSRP can appear first. All CRIs to be reported can be presented in descending order according to the corresponding predicted RSRP values. Alternatively, the CRI associated with the maximum L1-RSRP can appear first, which can be the maximum among all predicted L1-RSRP and measured L1-RSRP. However, since the CRI to be reported can be selected based on the predicted L1-RSRP, and the L1-RSRP to be reported for this CRI can be the measured L1-RSRP (instead of the corresponding predicted L1-RSRP), the maximum predicted L1-RSRP is not necessarily the maximum among all L1-RSRP to be reported. For the same reason, the reported measured L1-RSRP is not necessarily the maximum reported RSRP.

[0050] Differential RSRP Report with Amplitude Indicator

[0051] According to some embodiments of the present disclosure, the RSRP / SINR report value includes: a first RSRP / SINR report value corresponding to the first predicted or measured RSRP / SINR of the CRI or SSBRI with the largest predicted RSRP / SINR among the predicted RSRPs with CRI or SSBRI; and at least one differential report value indicating at least one difference between the first predicted or measured RSRP / SINR and the second predicted or measured RSRP / SINR.

[0052] According to some embodiments, the reported RSRP / SINR report value further includes: providing an indicator corresponding to the at least one differential report value to indicate whether the difference is positive or negative.

[0053] According to some embodiments, the received RSRP / SINR report value further includes: receiving an indicator corresponding to the at least one difference report value to indicate whether the difference is positive or negative.

[0054] As Figure 11 shown, according to some embodiments of the present disclosure, the Top-1 L1-RSRP is selected and quantized into an X1-bit value with a Y1dB step within a predefined range. The Top-1 L1-RSRP can be the first-occurring RSRP in the reported RSRP. The selection can be made based on the predicted L1-RSRP of the candidate CRI or candidate beam. Taking Table 1 as an example, the step refers to the dB range covered by each row in Table 1, and the step in Table 1 is 1dB. When the measured / predicted quantity value is given, Table 1 can be used to determine the corresponding report value (in the first column). For example, when the measured or predicted L1-RSRP is -139dBm, according to Table 1, the corresponding report value should be RSRP_16. RSRP_16 can be an X1-bit value. Table 1 is only an example; the step of this table can be different from Table 1.

[0055] It should be noted that the selected Top-1 L1-RSRP may not be the largest L1-RSRP. As described above, the Top-1 L1-RSRP can be the measured L1-RSRP with the largest corresponding predicted L1-RSRP. The CRI associated with the Top-1 L1-RSRP can first appear in the CSI field in a report.

[0056] According to some embodiments, for other L1-RSRP to be reported, a differential L1-RSRP reporting method can be used. For example, for other L1-RSRP that needs to be reported, the corresponding differential L1-RSRP is quantized into an X2-bit value, and with reference to the Top-1 L1-RSRP value that is part of the same L1-RSRP reporting instance, the corresponding differential L1-RSRP value is calculated in Y2dB steps. For example, calculate the differential L1-RSRP (ΔRSRP in Table 2) representing the difference between the L1-RSRP and the Top-1 L1-RSRP. Referring to Table 2, assuming ΔRSRP is -6dB, the corresponding differential reporting value is DIFFRSRP_3, which can be an X2-bit value. The Y2dB step refers to the range covered by each row in Table 2, taking 2dB as an example in Table 2. For example, X1 = 7, Y1 = 1, X2 = 4, Y2 = 2, and the predefined range is [-140, -44]dBm. It should be noted that the "one (or more) differences" for the differential reporting method in the present disclosure can be obtained by subtracting the reference value from the corresponding value, or by subtracting the corresponding value from the reference value. These two calculations have opposite signs, but the present disclosure is not limited to any one method.

[0057] Additionally or alternatively, a 1-bit amplitude indicator with a value of 1 or 0 can be provided for each differential L1-RSRP. The amplitude indicator can indicate whether the amplitude of the corresponding L1-RSRP is greater than or not greater than the amplitude of the Top-1 L1-RSRP. Or, the amplitude indicator can be used to indicate respectively whether the amplitude of the corresponding L1-RSRP is not greater than or greater than the amplitude of the Top-1 L1-RSRP. As mentioned above, since the Top-1 L1-RSRP is not necessarily the largest RSRP to be reported, the difference between the Top-1 L1-RSRP and the remaining L1-RSRP can be positive or negative. Although Table 2 may not necessarily reflect whether the difference value indicates that the Top-1 L1-RSRP or other RSRP is larger, the amplitude indicator can tell the BS the relationship between the Top-1 L1-RSRP and the RSRP. For example, in the case where the value of the amplitude indicator is 0 indicating that the Top-1 L1-RSRP is larger and the value of 1 indicating that the corresponding RSRP is larger, assuming the received indicator is 0 (indicating that the Top-1 L1-RSRP is larger), the BS understands that the actual value of the corresponding RSRP can be obtained by subtracting the reported corresponding value of the other RSRP from the reported value of the Top-1 L1-RSRP. If, under the same setting, the received indicator is 1 (i.e., the corresponding RSRP is larger), the BS understands that the actual value of the other party's RSRP can be obtained by adding the reported differential value of the other RSRP to the reported value of the Top-1 L1-RSRP.

[0058] Differential RSRP reporting with amplitude indicator for selected differential RSRP

[0059] According to some embodiments, the reported RSRP / SINR report value further includes: providing an indicator corresponding to at least one differential report value to indicate whether the difference is positive or negative.

[0060] According to some embodiments, the reported RSRP / SINR report value further includes: determining whether the difference satisfies a preset condition; and when the preset condition is satisfied, providing an indicator to identify at least one differential report value.

[0061] According to some embodiments, receiving the RSRP / SINR report value includes: when the difference satisfies a preset condition, receiving an indicator to identify at least one differential report value.

[0062] According to some embodiments, the preset condition is (a) the difference is greater than zero, or (b) the difference is less than or equal to zero.

[0063] According to some embodiments, when the condition is satisfied, the bit width of the indicator plus the differential report value is equal to the bit width of the differential report value when the condition is not satisfied.

[0064] According to some embodiments, the method further includes: when the difference satisfies a preset condition, converting the difference according to a first set of settings, and when the difference does not satisfy the preset condition, converting the difference according to a second set of settings, where the settings include the bit width of the differential report value and the step size of the conversion scale.

[0065] Alternatively, as Figure 12 shown, according to some embodiments of the present disclosure, the Top-1 L1-RSRP (such as Figure 13 RSRP#1 therein) can be selected (e.g., based on the predicted L1-RSRP of the candidate CRI), and quantized into an X3-bit value within a predefined range with a step size of Y3 dB.

[0066] It should be noted that the selected Top-1 L1-RSRP may not be the largest L1-RSRP. As described above, the Top-1 L1-RSRP can be the measured L1-RSRP with the largest corresponding predicted L1-RSRP. The CRI associated with the Top-1 L1-RSRP can appear first in the CSI field in a report.

[0067] According to some embodiments, a reporting method based on differential L1-RSRP is used. For example, for other L1-RSRPs to be reported that are not greater than the Top-1 L1-RSRP (such as at least one ofThe RSRP#2 and RSRP#4 in), the corresponding differential L1-RSRP can be quantized into an X4-bit value, and referring to the Top-1 L1-RSRP value as part of the same L1-RSRP reporting instance, calculate the corresponding differential L1-SINR value in Y4dB steps. For other L1-RSRPs to be reported that are greater than the Top-1 L1-RSRP (such as ​ The RSRP#3 in), the corresponding differential L1-RSRP can be quantized into an X5-bit value, and referring to the Top-1 L1-RSRP value, calculate the corresponding differential L1-SINR value in Y5dB steps, and provide a 1-bit amplitude indicator (whose value is 1 or 0) to indicate that the amplitude of the corresponding L1-RSRP is greater than the amplitude of the Top-1 L1-RSRP.

[0068] With ​ The use of the amplitude indicator, the operation of the differential value, and how the BS obtains the actual value of the L1-RSRP reported by the differential value have been explained in the first example associated with. Respectively with ​ And ​ The differences between the reporting methods associated with include that, in ​ The amplitude indicator is only associated with certain differential L1-RSRPs (RSRP#3), which correspond to the original RSRP greater than (or less than) the Top-1 L1-RSRP. However, in ​ Each reported differential RSRP can be equipped with an amplitude indicator. Assuming ​ The amplitude indicator in is used to indicate the original RSRP of the differential RSRP greater than the Top-1 L1-RSRP, then the BS can assume that those reported differential RSRPs without an amplitude indicator correspond to the original RSRP less than or equal to the Top-1 L1-RSRP.

[0069] Due to the addition of the reporting of a 1-bit amplitude indicator, the bit width X5 for reporting L1-RSRP greater than the Top-1 L1-RSRP may be less than the bit width X4 for reporting L1-RSRP not greater than the Top-1 L1-RSRP. To maintain the consistency of the bit width of each differential L1-RSRP report, more than two L1-RSRP measurement report mappings with different quantization bits and / or steps can be used for differential L1-RSRP reporting. The step or L1-RSRP measurement report mapping adopted can be indicated from the UE to the network. Therefore, regardless of whether the original RSRP is greater than the Top-1 L1-RSRP, the bit width of the differential RSRP can be the same. For example, X3 = 7, Y3 = 1, X4 = 4, Y4 = 2, X5 = 3, Y5 = 4, and the predefined range is [-140, -44] dBm.

[0070] Differential RSRP with position indicator

[0071] According to some embodiments, a location indicator may be used. The location indicator indicates at least one of a CRI or an SSBRI corresponding to a maximum predicted RSRP / SINR, a maximum RSRP / SINR reported value, or maximum confidence information.

[0072] Alternatively, as ​ shown, according to some embodiments of the present disclosure, the maximum value of L1-RSRP ( ​ RSRP#3 in ​ ) is selected and quantized to an X6-bit value within a predefined range with a step size of Y6 dB; the differential L1-RSRP is quantized to an X7-bit value. The differential L1-RSRP value is calculated with a step size of Y7 dB with reference to the maximum L1-RSRP value (

[0073] RSRP#3 in ​ ) that is part of the same L1-RSRP reporting instance. In these examples, the CRI associated with the maximum L1-RSRP ( ​ CRI#3 and RSRP#3 in ) may not appear first in a reported CSI field. Thus, a location indicator with a bit width of ​ may be reported by the UE to the BS to indicate the location of the maximum L1-RSRP in a reported CSI field, where N is the number of RS resources to be reported (4 as an example in

[0074] ), and

[0075] is the ceiling function of value x. As

[0076] shown, the location indicator is set to '10' to indicate that the L1-RSRP associated with the third reported CRI is the maximum L1-RSRP. It should be noted that the location indicator for identifying the maximum RSRP and / or its corresponding CRI can be applied to and combined with other embodiments of the present disclosure.

[0077] According to some embodiments of the present disclosure, the UE may provide an indicator in the report of CRI and / or RSRP. The indicator can be used to indicate the reported value corresponding to the measured L-RSRP or the predicted L-RSRP, respectively. For example, the value "0" of the indicator can be used to indicate that the reported value corresponds to the measured L-RSRP, while the value "1" of the indicator can be used to indicate that the reported value corresponds to the predicted L-RSRP.

[0078] As ​ shown, the Top-1 L1-RSRP (such as the maximum value of L1-RSRP) is selected and quantized into an X1-bit value within a predefined range with a step size of Y1 dB (as shown by RSRP#1 in ​ ), and the differential L1-RSRP is quantized into an X2-bit value. Referring to the Top-1 L1-RSRP value that is part of the same L1-RSRP reporting instance, the differential L1-RSRP value is calculated with a step size of Y2 dB. Therefore, the differential L1-RSRP value represents the difference between the corresponding L1-RSRP and the Top-1 L1-RSRP. Additionally, each L1-RSRP is associated with a 1-bit amplitude indicator with a value of 1 or 0 to indicate whether the corresponding L1-RSRP is the measured L1-RSRP or the predicted L1-RSRP, or vice versa. For example, X1 = 7, Y1 = 1, X2 = 4, Y2 = 2, and the predefined range is [-140, -44] dBm.

[0079] Different bit widths and / or step sizes of the measured L-RSRP

[0080] According to some embodiments, the settings for converting the original RSRP to the RSRP value to be reported can be different for the measured RSRP and the predicted RSRP, respectively. For example, the mapping that maps the RSRP to the RSRP value to be reported shown in Table 1 and / or Table 2 may be different for the measured RSRP and the predicted RSRP. The step size used to convert the original RSRP to the reported value may be different. In addition, the bit widths of the reported RSRP values corresponding to the measured RSRP and the predicted RSRP, respectively, may be different.

[0081] For example, as ​ shown, the Top-1 L1-RSRP (such as the maximum value of L1-RSRP) is selected and quantized into an X3-bit value within a predefined range with a step size of Y3 dB (as shown in ​RSRP in it #1). For the measured L1-RSRP report, the corresponding differential L1-RSRP can be quantized into an X4-bit value, and with reference to the Top-1 L1-RSRP value that is part of the same L1-RSRP report instance, calculate this corresponding differential L1-RSRP value in steps of Y4 dB. For the predicted L1-RSRP report, the corresponding differential L1-RSRP is quantized into an X5-bit value, and with reference to the Top-1 L1-RSRP value that is part of the same L1-RSRP report instance, calculate this corresponding differential L1-RSRP value in steps of Y5 dB. For example, X3 = 7, Y3 = 1, X4 = 4, Y4 = 2, X5 = 3, Y5 = 2, and the predefined range is [-140, -44] dBm. Here, the step sizes Y3 and Y4 of the predicted L1-RSRP and the measured L1-RSRP are different, and the bit widths X4 and X5 of the predicted L1-RSRP and the measured L1-RSRP are different. It should be noted that this method of using different bit widths and / or step sizes for the measured and predicted RSRP can be combined with different methods in this disclosure. For example, various indicators disclosed in this disclosure can be used together.

[0082] According to some embodiments, the BS and the UE can have a preset resource set, and based on whether the measured / reported CRI or SSBRI belongs to this resource set, select the conversion setting for generating the reported value of the L1-RSRP. In addition, an amplitude indicator can be provided based on whether the reported CRI or SSBRI belongs to this resource set. Additionally, the BS and the UE can determine the preset resource set as the resource set for measurement. The preset resource set can be the measured resource set for which the channel characteristics have been measured.

[0083] For example, as ​ shown, select the Top-1 L1-RSRP (such as the maximum value of the L1-RSRP), and quantize it into an X3-bit value within the predefined range, with a step size of Y3 dB (as ​RSRP in

[0084] As an alternative example, the CRI of the selected Top-1 L1-RSRP does not belong to the measured resource set. In this case, if the CRI to be reported is not from the measured resource set, the corresponding differential L1-RSRP can be quantized to an X4-bit value, and the value of the Top-1 L1-RSRP as part of the same L1-RSRP reporting instance can be referred to, and the corresponding differential L1-RSRP value can be calculated in Y4 dB steps. Otherwise, if the CRI to be reported is from the measured resource set, the corresponding differential L1-RSRP can be quantized to an X5-bit value, and the Top-1 L1-RSRP value can be referred to and the corresponding differential L1-RSRP value can be calculated in Y5 dB steps; a 1-bit amplitude indicator associated with a value of 1 or 0 indicates that the amplitude of the corresponding L1-RSRP is greater than or not greater than the amplitude of the Top-1 L1-RSRP, or indicates that the amplitude of the corresponding L1-RSRP is not greater than or greater than the amplitude of the Top-1 L1-RSRP. For example, X3 = 7, Y3 = 1, X4 = 4, Y4 = 2, X5 = 3, Y5 = 2.

[0085] CRI / SSBRI and / or confidence information reporting method

[0086] According to some embodiments of the present invention, the CSI-related quantity to be reported by the UE is the CRI and the confidence level (confidence information), or only the confidence level. The confidence level can be obtained by the inference of a functional module (such as an artificial intelligence or machine learning model or function) deployed on the UE side, and the confidence level represents the probability that the corresponding CRI is associated with the maximum measured value of the L1-RSRP.

[0087] For the confidence level report, two or more reporting methods with different quantization bits and / or step sizes can be configured and indicated by the network. Optionally, the UE is set with a threshold for the confidence level report, and confidence levels below the threshold are not expected to be reported. Additionally, for the mapping order of a reported CSI field, the CRI associated with the maximum confidence level can be presented first. All CRIs to be reported are arranged in descending order of the corresponding confidence levels.

[0088] CRI and Confidence Information Reporting

[0089] According to some embodiments of the present disclosure as ​ shown, all confidence levels corresponding to different CRIs to be reported can be quantized into X1-bit values within a predefined range with a step size of Y1. For example, X1 = 7, Y1 = 1, and the predefined range is [0, 100] or [0, 1]. Similar to Table 1, the confidence levels can be mapped from their original values to reported values for reporting. X1 represents the bit width of the reported value after conversion, and the step size represents the range covered by the confidence levels of each row of the reported value.

[0090] Saving Overhead by Omitting Confidence Information of at Least One CRI

[0091] According to some embodiments, multiple confidence information indicates the last unreported confidence information of the CRI or SSBRI.

[0092] According to some embodiments, the method further includes the BS using the received multiple confidence information to generate unreported confidence information corresponding to the reported CRI.

[0093] According to ​ some embodiments of the present disclosure as shown, for all CRIs to be reported, one of the corresponding confidence levels (e.g., the confidence level of CRI#4) is not reported. For example, the skipped confidence level can be the confidence level with the maximum value, or the confidence level associated with the first reported CRI or the last reported CRI. The skipped confidence level can be derived from the (one or more) other confidence levels reported by the BS. For example, the sum of all confidence levels including the skipped confidence level can be a number known to the BS and the UE. Therefore, the BS can obtain the skipped confidence level by subtracting the other reported confidence levels from the known number. Thus, the reported confidence level represents the skipped confidence level. Additionally or alternatively, the reported confidence levels corresponding to different CRIs to be reported are quantized into X1-bit values within a predefined range with a step size of Y1. For example, X1 = 7, Y1 = 1, and the predefined range is [0, 100] or [0, 1].

[0094] Reporting with Difference Values and Magnitude Indicators

[0095] According to some embodiments, multiple confidence information includes: first confidence information corresponding to a first confidence value; and at least one second confidence information indicating at least one difference between the first confidence value and a second confidence value.

[0096] According to some embodiments, reporting multiple confidence information includes: providing an indicator corresponding to at least one difference to indicate whether the difference is positive or negative.

[0097] According to some embodiments, receiving multiple confidence information includes: receiving an indicator corresponding to at least one difference to indicate whether the difference is positive or negative.

[0098] According to some embodiments, the bit width of the first confidence information may be the same as or different from the bit width of at least one second confidence information plus the indicator.

[0099] The above method for reporting difference values of L1-RSRP can be applied to report confidence levels. According to ​ some embodiments of the present disclosure as shown, the Top-1 confidence level (such as ​ probability #1 in) can be selected according to the inference of the functional module, and quantized into an X4-bit value within a predefined range with a step size of Y4dB. The selected Top-1 confidence level is not necessarily the maximum confidence level, and the CRI associated with the Top-1 confidence level can be presented in a reported CSI field first.

[0100] For other confidence levels to be reported, a differential-based reporting method can be used. For example, for other confidence levels to be reported, the corresponding differential confidence level is quantized into an X5-bit value, and with reference to the Top-1 confidence level value as part of the same reporting instance, the corresponding differential confidence level value is calculated with a step size of Y5dB. The differential confidence level represents the difference between the corresponding confidence level and the Top-1 confidence level. As described above, the difference can be calculated by subtracting the corresponding confidence level from the reference confidence level or subtracting the reference confidence level from the corresponding confidence level. Additionally, each differential confidence level can be associated with a 1-bit amplitude indicator with a value of 1 or 0. The amplitude indicator can indicate that the amplitude of the corresponding confidence level is greater than or not greater than the amplitude of the Top-1 confidence level with values 0 and 1 respectively, or indicate that the amplitude of the corresponding confidence level is not greater than or greater than the amplitude of the Top-1 confidence level with values 0 and 1 respectively. As explained above when applying the amplitude indicator to report RSRP with difference values, the base station can determine whether the actual confidence level reported in the form of difference values should be added to or subtracted from the Top-1 confidence level value according to the amplitude indicator.

[0101] Location indicator for trust information report

[0102] According to some embodiments of the present disclosure, a location indicator may be introduced that indicates at least one of the CRI or SSBRI corresponding to the maximum predicted RSRP / SINR, the maximum RSRP / SINR reported value, or the maximum confidence information.

[0103] According to ​ Some embodiments of the present disclosure as shown, the maximum value of the confidence level may be selected and quantized into an X6-bit value within a predefined range with a step size of Y6 dB. The differential confidence level is quantized into an X7-bit value and calculated with a step size of Y7 dB with reference to the maximum confidence level value as part of the same L1-RSRP report instance. Additionally, a location indicator with a bit width of may be reported by the UE to the BS to indicate the location of the maximum confidence level in the CSI field in a report, where N is the number of RS resources to be reported, and is the ceiling function. As ​ shown, the location indicator is set to "10" to indicate that the confidence level associated with the CRI of the third report is the maximum confidence level.

[0104] Combination of different features

[0105] As repeatedly explained above, various features of the present disclosure may be combined or implemented together to report CRI, RSRP, and / or confidence information. As in the example of ​ , where one confidence level (and associated indicator) is not reported (corresponding to CRI#4), such as the confidence level with the maximum value, or the confidence level associated with the first reported CRI or the last reported CRI. The difference value and the magnitude indicator are implemented in ​ . Additionally, it should be noted that the CRI in the present disclosure may be replaced with SSBRI, and the RSRP may be replaced with SINR.

[0106] Report selection

[0107] According to some embodiments of the present disclosure, the report includes reporting at least one of the following combinations: the RSRP / SINR reported value and multiple confidence information; the CRI and the RSRP / SINR reported value; or the SSBRI and the RSRP / SINR reported value.

[0108] According to some embodiments of the present disclosure, the report includes reporting two of the CRI, SSBRI, RSRP / SINR reported value, and multiple confidence information.

[0109] According to some embodiments of the present invention, the CSI-related quantities to be reported by the UE to the BS may be the CRI, L1-RSRP, and confidence level, or just L1-RSRP and confidence level. For L1-RSRP reporting, one of the L1-RSRP reporting methods described above, their combination, or a conventional method may be used. For confidence level reporting, one of the confidence level reporting methods described above or their combination may be used. Additionally, the UE may also be set with a threshold for confidence level reporting. It is not expected that the predicted L1-RSRP associated with a confidence level below the threshold will be reported.

[0110] Resource Request Indicator for CSI

[0111] According to some embodiments of the present disclosure, in the CSI report, a 1-bit resource request indicator with a value of 1 or 0 may be associated with each reporting instance. The resource request indicator may be provided to indicate whether the UE requests additional RS resources for channel measurement.

[0112] Additionally, in the CSI report, each CRI to be reported may be associated with an additional indicator to implicitly indicate the Rx beam information. The bit width of the additional indicator is where N is the number of Rx beams or the number of RS resources to be reported, and is the ceiling function.

[0113] For the purpose of beam indication, the TCI state or channel (such as PDCCH, PDSCH, etc.) or reference signal (e.g., NZP-CSI-RS, SSB, etc.) may be associated with the parameters of a specific CSI report or CSI-related quantities, such as the most recent CSI report or the CSI report at a specific time. For example, by configuring or activating the TCI state or CSI-RS / SSB resources associated with the additional indicator in a specific CSI report, the UE can be indicated the Rx beam or spatial Rx parameters.

[0114] Report order

[0115] The above reports from the UE group the confidence level, RSRP, and their associated CRI together, but this arrangement is merely an example. According to other methods, the reported items of the same type may be arranged consecutively, but within each group, the order may still follow the order described in the present disclosure, for example, in descending order according to RSRP or confidence level. For example ​ as shown, CSR / SSBRI #1 to #4 are arranged consecutively. After CSR / SSBRI is the RSRP (whether in differential format or not) and any possible indicators. In each group of RSRP or indicators, the order may follow the same order as CSR / SSBRI. As ​As shown, the same method also applies to the reporting of CSR / SSBRI and confidence levels.

[0116] This disclosure describes various exemplary embodiments with reference to the accompanying drawings so that those of ordinary skill in the art can make and use the disclosure. The disclosure is not limited to the exemplary embodiments and applications described and illustrated herein. Additionally, the specific order and / or hierarchy of steps in the methods disclosed herein are merely exemplary methods. Depending on design preferences, the specific order or hierarchy of the steps of the disclosed methods or processes can be rearranged while still remaining within the scope of the disclosure. Thus, those of ordinary skill in the art should understand that the methods and processes disclosed herein present various steps or acts in an exemplary order, and the disclosure is not limited to the one or more specific orders or hierarchies presented unless otherwise expressly stated.

[0117] The present invention is intended to cover any conceivable variations, uses, combinations, or adaptive changes to the disclosure that follow its general principles, and includes knowledge and conventional technical means known in the art as well as variations, uses, combinations, or adaptive changes not disclosed in the present disclosure.

[0118] It should be understood that the present disclosure is not limited to the exact structures or operations described above and shown in the drawings, and various modifications and changes can be made without departing from the scope of the present disclosure. The scope of the present disclosure is defined only by the appended claims.

[0119] The methods, devices, processes, circuits, and logics described above can be implemented in many different ways and in many different combinations of hardware and software. For example, all or part of the implementation can be a circuit including an instruction processor or controller, such as a central processing unit (CPU), a microcontroller, or a microprocessor; or as an application specific integrated circuit (ASIC), a programmable logic device (PLD), or a field programmable gate array (FPGA); or as a circuit including discrete logic or other circuit elements, including analog circuit elements, digital circuit elements, or both; or any combination thereof. For example, the circuit can include discrete interconnected hardware components, or can be implemented on a single integrated circuit chip, distributed among multiple integrated circuit chips, or in a multi-chip module (MCM) of multiple integrated circuit chips in a common package.

[0120] Thus, the circuit can store or access instructions for execution, or can implement its functionality solely in hardware. The instructions can be stored in a tangible storage medium other than a transient signal, such as flash memory, random access memory (RAM), read only memory (ROM), erasable programmable read only memory (EPROM); or on a magnetic disk or optical disk, such as compact disc read only memory (CDROM), hard disk drive (HDD) or other magnetic or optical disk; or in or on another machine-readable medium. A product (such as a computer program product) can include a storage medium and instructions stored in or on the medium, and when the instructions are executed by a circuit in a device, can cause the device to implement any of the processes described above or shown in the figures.

[0121] The implementation can be distributed. For example, the circuit can include multiple different system components, such as multiple processors and memories, and can span multiple distributed processing systems. Parameters, databases and other data structures can be stored and managed separately, can be combined into a single memory or database, can be organized logically and physically in many different ways, and can be implemented in many different ways. Example implementations include linked lists, program variables, hash tables, arrays, records (such as database records), objects and implicit storage mechanisms. The instructions can form parts of a single program (e.g., subroutines or other code parts), can form multiple separate programs, can be distributed across multiple memories and processors, and can be implemented in many different ways. Example implementations include stand-alone programs, and as part of a library, such as a shared library like a dynamic link library (DLL). For example, the library can contain shared data and one or more shared programs, the programs including instructions for a circuit to perform any of the processes described above or shown in the figures.

[0122] In some examples, each unit, subunit, and / or module of a system can include a logic component. Each logic component can be hardware or a combination of hardware and software. For example, each logic component can include an Application Specific Integrated Circuit (ASIC), a Field Programmable Gate Array (FPGA), digital logic circuitry, analog circuitry, a combination of discrete circuitry, gates, or any other type of hardware or a combination thereof. Alternatively or additionally, each logic component can include memory hardware, such as a portion of a memory that includes instructions executable by the processor or other processors to implement one or more features of the logic component. When any one logic component includes a memory portion containing instructions executable by a processor, the logic component may or may not include a processor. In some examples, each logic component can be just a portion of a memory or other physical memory that includes instructions executable by a processor or other processors to implement the features of the corresponding logic component without the logic component including any other hardware. Because each logic component includes at least some hardware, even if the hardware included is software, each logic component can also be referred to interchangeably as a hardware logic component.

[0123] A second action can be said to be "responsive to" a first action, regardless of whether the second action is directly or indirectly caused by the first action. The second action may occur much later in time than the first action but is still a response to the first action. Similarly, even if intermediate actions occur between the first action and the second action, and even if one or more of the intermediate actions directly cause the execution of the second action, the second action can still be said to be a response to the first action. For example, if the first action sets a flag, the second action may be a response to the first action, and a third action later initiates the second action when the flag is set.

In other words, the phrase means any combination of one or more of the elements A, B, ..., or N, including any one of the elements alone or a combination of that one element with one or more other elements, and such combinations may also include combinations of other elements not listed."< / n>
