[0025] Fig. 1 illustrates a block diagram of an exemplary wireless communication system 10, in accordance with some embodiments of this disclosure. The system 10 may perform the methods / steps and their combination disclosed in this disclosure. The system 10 may include components and elements configured to support operating features that need not be described in detail herein.
[0026] The system 10 may include a base station (BS) 110 and 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 BS 110 may be electrically coupled and in communication with one another as necessary via a data communication bus 180. Likewise, 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 in communication with one another as necessary via a data communication bus 190. The BS 110 communicates with the UE 120 via communication channels therebetween, which can be any wireless channel or other medium known in the art suitable for transmission of data as described herein.
[0027] The processor modules 113, 123 may be implemented, or realized, with 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, designed to perform the functions described herein. In this manner, a processor module may be realized as a microprocessor, a controller, a microcontroller, a state machine, or the like. A processor module may also be implemented as a combination of computing devices, e.g., a combination of a digital signal processor and a microprocessor, a plurality of microprocessors, one or more microprocessors in conjunction with a digital signal processor core, or any other such configuration.
[0028] Furthermore, the steps of a method or algorithm described in connection with the embodiments disclosed herein may be embodied directly in hardware, in firmware, in a software module performed by processor modules 113, 123, respectively, or in any practical combination thereof. The memory modules 113, 123 may be realized as RAM memory, flash memory, EEPROM memory, registers, ROM memory, EPROM memory, a hard disk, a removable disk, a CD-ROM, or any other form of storage medium known in the art. In this regard, the memory modules 114, 124 may be coupled to the processor modules 113, 123 respectively, such that the processors modules 113, 123 can read information from, and write information to, memory modules 114, 124 respectively. The memory modules 114, 124 may also be integrated into their respective processor modules 113, 123. In some embodiments, the memory modules 114, 124 may each include a cache memory for storing temporary variables or other intermediate information during execution of instructions to be performed by processor modules 113, 123, respectively. The memory modules 114, 124 may also each include non-volatile memory for storing instructions to be performed by the processor modules 113, 123, respectively.
[0029] In the related art, UE is configured with at least one resource settings for channel measurement and at least one reporting settings for CSI report. For example, the BS can send an RRC message or other control signal to control the UE on what kind of information need to be reported to the BS. Each reporting setting contains the parameters for one CSI reporting band and the CSI related quantities to be reported by the UE. For beam management, the CSI related quantities to be reported by the UE can be indicated by the higher layer parameter reportQuantity in the reporting setting, and the higher layer parameter mainly include CSI-RS resource indicator (CRI) , SS / PBCH Block Resource indicator (SSBRI) , L1-RSRP (Layer 1-Reference signal receiving power) or L1-SINR (Layer 1-Signal to interference plus noise ratio) .
[0030] More specifically, a 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’ , the UE may report one or multiple CRIs and associated L1-RSRP in a single report for each report setting, where the number of RS resources to be reported is configured by the higher layer.
[0031] For L1-SINR reporting, if the number of RS (Reference Signal) resources to be reported per report setting is configured to as one, the reported L1-SINR value is defined by a 7-bit value in a range of [-23, 40] dB with a 0.5 dB step size. If the number of measured RS resources to be reported per report setting is configured to be larger than one, the UE may use differential L1-SINR based reporting, where the largest measured value of L1-SINR is quantized to a 7-bit value in the range of [-23, 40] dB with a 0.5 dB step size. The differential L1-SINR is quantized to a 4-bit value. The differential L1-SINR value is computed with a 1 dB step size with a reference to the largest measured L1-SINR value which is a part of the same L1-SINR reporting instance.
[0032] For L1-RSRP reporting, if the number of RS resources to be reported per report setting is configured to be one, the reported L1-RSRP value can be defined by a 7-bit value in the range of [-140, -44] dBm with a 1-dB step size. If the number of measured RS resources to be reported per report setting is configured to be larger than one, the UE may use differential L1-RSRP based reporting, where the largest measured value of L1-RSRP is quantized to a 7-bit value in the range of [-140, -44] dBm with a 1-dB step size. The differential L1-RSRP is quantized to a 4-bit value, and the differential L1-RSRP value is computed with a 2-dB step size with a reference to the largest measured L1-RSRP value, which is a part of the same L1-RSRP reporting instance. The mapping of measured quantity is defined as an example in the following tables.
[0033] Table 1: L1-RSRP measurement report mapping
[0034] Table 2: Differential L1-RSRP measurement (for L1 reporting) report mapping
[0035] 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, a UE can provide a probability or confidence that the corresponding resource indicator is associated with the strongest RSRP. In addition, a RSRP or SINR can be predicted or estimated according to other information obtain by UE. For example, the UE can measure only a couple of RSRPs or SINRs (measured RSRPs or SINRs) and use these measured values to estimated or predicted other RSRPs or SINRs (predicted RSRPs or SINRs) for other channels or beams. Therefore, different types of RSRPs or SINRs can be provided. According to some embodiments, the predicted RSRPs or SINRs can be the first type of RSRPs or SINRs, and the measured RSRPs or SINRs can be the second type, or vise versa.
[0036] According to some embodiments of this disclosure, a wireless communication method is provided. The method includes receiving, by a first wireless communication node from a second communication node, a report configuration; and reporting, by the first wireless communication node according to the report configuration, at least one of: CSI Reference Signal Resource Indicators (CRIs) ; SS / PBCH Block Resource Indicators (SSBRIs) ; RSRP (Reference signal receiving power) / SINR (Signal to interference plus noise ratio) report values corresponding to predicted or measured RSRPs / SINRs of the CRIs or SSBRIs; or a plurality of pieces of confidence / probability information corresponding to confidence / probability values of the one or more CRIs or SSBRIs, wherein: the reporting accords to a report order based on predicted RSRP / SINR corresponding to the CRIs or SSBRIs; the reporting accords to a report order based on the plurality of pieces of confidence / probability information corresponding to the CRIs or SSBRIs; or the reporting includes providing a location indicator identifying one of the reported CRIs, SSBRIs, RSRP / SINR report values, or the plurality of pieces of confidence / probability information.
[0037] According to some embodiments of this disclosure, another wireless communication method is provided. The method includes sending, by a second wireless communication node to a first communication node, a report configuration; and receiving, by the second wireless communication node according to the report configuration, at least one of: CSI Reference Signal Resource Indicators (CRIs) ; SS / PBCH Block Resource Indicators (SSBRIs) ; RSRP / SINR report values corresponding to predicted or measured RSRPs / SINRs of the CRIs or SSBRIs; or a plurality of pieces of confidence / probability information corresponding to confidence / probability values of the one or more CRIs or SSBRIs, wherein: the reporting accords to a report order based on predicted RSRP / SINR corresponding to the CRIs or SSBRIs; the reporting accords to a report order based on the plurality of pieces of confidence / probability information corresponding to the CRIs or SSBRIs; or the reporting includes receiving a location indicator identifying one of the reported CRIs, SSBRIs, RSRP / SINR report values, or the plurality of pieces of confidence / probability information.
[0038] According to some embodiments, the report order presents the CRIs or SSBRIs based on the predicted RSRPs / SINRs or the corresponding one or more confidence values corresponding to the CRIs or SSBRIs in a descending order.
[0039] According to some embodiments, the report order presents the RSRP report values based on the corresponding one or more predicted RSRPs / SINRs in a descending order.
[0040] According to some embodiments, the report order presents the plurality pieces of confidence / probability information based on the confidence / probability values in a descending order.
[0041] According to some embodiments, the method further includes determining whether a predicted RSRP / SINR corresponding to a candidate CRI is smaller than a threshold; and determining not to report the candidate CRI’s predicted RSRP / SINR if the predicted RSRP / SINR corresponding to the candidate CRI is smaller than the threshold.
[0042] According to some embodiments, the method further includes determining whether a confidence / probability information corresponding to a candidate CRI is smaller than a threshold; and determining not to report the candidate CRI’s confidence / probability information if the confidence / probability information corresponding to the candidate CRI is smaller than the threshold.
[0043] CRI / SSBRI and / or RSRP / SINR Report Approaches
[0044] The explanation below uses CRI and RSRP as examples, but it should be noted that the CRI below can be replaced with a SSBRI and that the RSRP can be replaced with a SINR to implement the channel monitoring and reporting. The description would not repeat the examples with such replacement again.
[0045] According to some embodiments of this disclosure, the CSI related quantities to be reported by the UE may include CRI and L1-RSRP, or alternatively only L1-RSRP. The L1-RSRP to be reported by UE may be obtained by measurement by the UE or by inference of functional modules (such as artificial intelligence or machine learning models or functionalities) deployed at the UE. The functional modules can infer a predicted L1-RSRP for each CRI. For each CRI to be reported, the associated L1-RSRP can be obtained by UE measurement if possible (i.e., the measured L1-RSRP) . Otherwise, the associated L1-RSRP to be reported can be obtained by inference of the functional modules (i.e., the predicted L1-RSRP) . According to some embodiments of this disclosure, when a measured L1-RSRP and corresponding predicted L1-RSRP are both existed, the UE may preferably report the measured L1-RSRP of a CRI.
[0046] For the L1-RSRP reporting, two or more L1-RSRP reporting methods with different quantization bits and / or step sizes can be configured and indicated by the network, such as the legacy method and the following enhanced L1-RSRP reporting method.
[0047] According to some embodiments of this disclosure, the UE can be configured with a threshold for the predicted L1-RSRP reporting. A predicted L1-RSRP lower than the threshold is not expected to be reported by the UE to the BS. Alternatively, a predicted L1-RSRP lower than or equal to the threshold is not expected to be reported by the UE to the BS.
[0048] According to some embodiments of this disclosure regarding the mapping order of CSI fields of one report, the CRI associated with the largest predicted L1-RSRP can be present first. All CRIs to be reported can be presented according to the corresponding predicted RSRP values in a descending order. Alternatively, the CRI associated with the largest L1-RSRP can be present first, which can be the largest over all predicted L1-RSRP and measured L1-RSRP. However, because the selection of the to-be-reported CRI can be based on the predicted L1-RSRP, but the to-be-reported L1-RSRP of the CRI can be the measured L1-RSRP (instead of the corresponding predicted L1-RSRP) , the largest predicted L1-RSRP may not be the largest of all L1-RSRPs to be reported. For the same reason, the reported measured L1-RSRP may not necessarily be the largest reported RSRP.
[0049] Differential RSRP Report with Amplitude Indicator
[0050] According to some embodiments of this disclosure, the RSRP / SINR report values include: a first RSRP / SINR report value corresponding to a first predicted or measured RSRP / SINR of a CRI or SSBRI having the largest predicted RSRP / SINR among the predicted RSRPs of the CRIs or SSBRIs; and at least one differential report value indicating at least one difference between the first predicted or measured RSRP / SINR and a second predicted or measured RSRP / SINR.
[0051] According to some embodiments, reporting the RSRP / SINR report values further includes: providing an indicator corresponding to the at least one differential report value to indicate where the difference is positive or negative.
[0052] According to some embodiments, receiving the RSRP / SINR report values further includes: receiving an indicator corresponding to the at least one differential report value to indicate where the difference is positive or negative.
[0053] As shown in Fig. 2 and according to some embodiments of this disclosure, a Top-1 L1-RSRP is selected and quantized to a X1-bit value in a pre-defined range with a Y1 dB step size. The Top-1 L1-RSRP can be the RSRP presented first among the report RSRPs. The selection can accord to the predicted L1-RSRPs of candidate CRIs or candidate beams. Referring to Table 1 as an example, the step size refers to the covered dB range in each row in Table 1, and the step size is 1dB in Table 1. Table 1 can be used to determine the corresponding reported value (at the first column) when a measured / predicted quantity value is given. For example, when a measured or predicted L1-RSRP is -139 dBm, based on Table 1, the corresponding report value should be RSRP_16. RSRP_16 can be a X1-bit value. Table 1 is only an example; the step size of the table can be different from that of Table 1.
[0054] It is noted that the selected Top-1 L1-RSRP may not be the largest L1-RSRP. As explained above, the Top-1 L1-RSRP can be a measured L1-RSRP with the largest corresponding predicted L1-RSRP. The CRI associated with the Top-1 L1-RSRP can be present first in the CSI fields in one report.
[0055] According to some embodiments, for the other L1-RSRPs to be reported, a differential based L1-RSRP reporting approach can used. For example, for the other L1-RSRPs to be reported, the corresponding differential L1-RSRP is quantized to a X2-bit value and is computed with Y2 dB step size with a reference to the Top-1 L1-RSRP value, which is a part of the same L1-RSRP reporting instance. For example, a differential L1-RSRP indicated a L1-RSRP and Top-1 L1-RSRP (ΔRSRP in Table 2) is calculated. Referring to Table 2, assuming the ΔRSRP is -6 dB, the corresponding differential reported value is DIFFRSRP_3, which can be a X2-bit value. The Y2 dB step size refers to the range covered by each row in Table 2, which is 2dB as an example in Table 2. As an example, X1=7, Y1=1, X2=4, Y2=2, and the pre-defined range is [-140, -44] dBm. It is noted that the “difference (s) ” in this disclosure for the differential report approach can be derived by a respective value subtracted by the reference value, or alternatively the reference value subtracted by the respective value. The two calculations would have opposite sign, but this disclosure does not limit to either approach.
[0056] Additionally or alternatively, a 1-bit amplitude indicator with value of either 1 or 0 can be provided, associated with each differential L1-RSRP. The amplitude indicator can indicate the amplitude of the corresponding L1-RSRP is greater or not greater than that of the Top-1 L1-RSRP. Alternatively, the amplitude indicator can be used to indicate the amplitude of the corresponding L1-RSRP is not greater than or greater than that of the Top-1 L1-RSRP, respectively. As explained above, the Top-1 L1-RSRP is not necessary the largest RSRP to be reported, therefore the difference between the Top-1 L1-RSRP and the rest of the L1-RSRPs can be positive or negative. As Table 2 does not necessarily reflect whether the differential value indicate whether the Top-1 L1-RSRP or another RSRP is larger, the amplitude indicator can tell the BS the relationship between the Top-1 L1-RSRP and the RSRP. For example, in a case value 0 of the amplitude indicator indicates the Top-1 L1-RSRP is larger and value 1 indicated the respective RSRP is larger. Assuming the received indicator is 0 (indicating the Top-1 L1-RSRP is larger) , the BS understand that the actual value of the respective RSRP can be derived by the reported value of Top-1 L1-RSRP minus the reported respective value of the other RSRP. If the receive indicator is 1 under the same setting (meaning that the respective RSRP is larger) , the BS understand the actual value of the other RSRP can be derived by the reported value of Top-1 L1-RSRP plus the reported differential value of the other RSRP.
[0057] Differential RSRP Report with Amplitude Indicator for Selected Differential RSRP
[0058] According to some embodiments, reporting the RSRP / SINR report values further includes: providing an indicator corresponding to the at least one differential report value to indicate where the difference is positive or negative.
[0059] According to some embodiments, reporting the RSRP / SINR report values further includes: determining whether the difference meets a preset condition; and when the preset condition is met, providing an indicator to identify the at least one differential report value.
[0060] According to some embodiments, receiving the RSRP / SINR report values includes when the difference meets a preset condition, receiving an indicator to identify the at least one differential report value.
[0061] According to some embodiments, the preset condition is either (a) the difference is larger than zero or (b) the difference is smaller or equal than zero.
[0062] According to some embodiments, a bit width of the indicator plus the differential report value when the condition is met is equal to a bit width of the differential report value when the condition is not met.
[0063] According to some embodiments, the method further includes converting the difference according to a first set of settings when the difference meets the preset condition and converting the difference according to a second set of settings when the difference does not meet the preset condition, wherein the settings include a bit width of the differential report value and a step size of a converting scale.
[0064] Alternatively as shown in Fig. 3 according to some embodiments of this disclosure, a Top-1 L1-RSRP (such as RSRP#1 in Fig. 3) can be selected (for example based on the predicted L1-RSRP of candidate CRIs) and quantized to a X3-bit value in the pre-defined range with Y3 dB step size.
[0065] It is noted that the selected Top-1 L1-RSRP may not be the largest L1-RSRP. As explained above, the Top-1 L1-RSRP can be a measured L1-RSRP with the largest corresponding predicted L1-RSRP. The CRI associated with the Top-1 L1-RSRP can be present first in the CSI fields in one report.
[0066] According to some embodiments, a differential L1-RSRP based reporting method is used. For example, for other to-be-reported L1-RSRPs that is not greater the Top-1 L1-RSRP (such as RSRP#2 and RSRP#4 in Fig. 3) , the corresponding differential L1-RSRP can be quantized to a X4-bit value and is computed with Y4 dB step size with a reference to the Top-1 L1-RSRP value which is a part of the same L1-RSRP reporting instance. For other to-be-reported L1-RSRPs that is greater than the Top-1 L1-RSRP (such as RSRP#3 in Fig. 3) , the corresponding differential L1-RSRP can be quantized to a X5-bit value and is computed with Y5 dB step size with a reference to the Top-1 L1-RSRP value, and a 1-bit amplitude indicator with value of 1 or 0 can be provided to indicate the amplitude of the corresponding L1-RSRP is greater than that of the Top-1 L1-RSRP.
[0067] The use of the amplitude indicator, the operation of differential value, and how the BS can derive the actual value of the L1-RSRP reported by the differential value has been explained in the first example associated with Fig. 2. The difference between the report approaches respectively associated with Fig . 2 and Fig. 3 includes that in Fig. 3 the amplitude indicator is only associated with certain differential L1-RSRP (RSRP#3) , which corresponding to an original RSRP greater (or alternatively lesser) than the Top-1 L1-RSRP. Yet, in Fig. 2, each reported differential RSRP may be provided with an amplitude indicator. Assuming the amplitude indicator in Fig. 3 is used to indicate the original RSRP of the differential RSRP that is greater than the Top-1 L1-RSRP, the BS can assume that those reported differential RSRPs without an amplitude indicator corresponding to original RSRPs that are lessor or equal to the Top-1 L1-RSRP.
[0068] Due to the reporting of the additional 1-bit amplitude indicator, the bit width X5 for reporting L1-RSRP greater than the Top-1 L1-RSRP may be lower than the bit width X4 for reporting L1-RSRP not greater than the Top-1 L1-RSRP. To maintain a consistent bit width for each differential L1-RSRP reporting, two or more L1-RSRP measurement report mappings with different quantization bits and / or step sizes may be used for the differential L1-RSRP reporting. The adopted step size or L1-RSRP measurement report mapping may be indicated from UE to the Network. Therefore, the bit width of the differential RSRP can be the same, whether or not the original RSRP is larger than the Top-1 L1-RSRP or not. As an example, X3=7, Y3=1, X4=4, Y4=2, X5=3, Y5=4, and the pre-defined range is [-140, -44] dBm.
[0069] Differential RSRP with Location Indicator
[0070] According to some embodiments, a location indicator can be used. The location indicator indicating at least one of a CRI or SSBRI corresponding to a largest predicted RSRP / SINR, a largest RSRP / SINR report values, or a largest piece of confidence information.
[0071] Alternatively as shown in Fig. 4 according to some embodiments of this disclosure, the largest value of L1-RSRP (RSRP#3 in Fig. 4) is selected and quantized to a X6-bit value in a pre-defined range with Y6 dB step size; the differential L1-RSRP is quantized to a X7-bit value. The differential L1-RSRP value is computed with a Y7 dB step size with a reference to the largest L1-RSRP value (RSRP#3 in Fig. 4) , which is a part of the same L1-RSRP reporting instance.
[0072] In these examples, the CRI associated with the largest L1-RSRP (CRI#3 and RSRP#3 in Fig. 4) may not be presented first in the CSI fields of one report. Therefore, a location indicator with a bit width of can be reported by the UE to the BS, to indicate the location of the largest L1-RSRP in the CSI fields of one report, where N is the number of RS resources to be reported (which is 4 as an example in Fig. 4) and is the ceiling function of the value x. As shown in Fig. 4, the location indicator is set to ‘10’ to indicate that the L1-RSRP associated with the third reported CRI is the largest L1-RSRP. It should be noted that the location indicator used to identify the largest RSRP and / or its corresponding CRI can be applied on and combined with other embodiments of this disclosure.
[0073] Indicator Distinguishing Measured RSRP and Predicted RSRP
[0074] According to some embodiments, reporting the RSRP / SINR report values includes: providing a report indicator to indicate whether the predicted or measured RSRPs / SINRs corresponding to the RSRP / SINR report values are measured values or predicted values.
[0075] According to some embodiments, receiving the RSRP / SINR report values includes: receiving a report indicator to indicate whether the predicted or measured RSRPs / SINRs corresponding to the RSRP / SINR report values are measured values or predicted values.
[0076] According to some embodiments of this disclosure, the UE may provide an indicator in the report of the CRIs and / or RSRPs. The indicator can be used to indicate that the report values respectively corresponding to a measured L-RSRP or a predicted L-RSRP. For example, a value “0” of the indicator can be used to indicated that a reported value corresponds to a measured L-RSRP, and a value “1” of the indicator can be used to indicated that a reported value corresponds to a predicted L-RSRP.
[0077] As shown in Fig. 5, a Top-1 L1-RSRP (such as the largest value of L1-RSRP) is selected and quantized to a X1-bit value in a pre-defined range with Y1 dB step size (as shown in RSRP#1 in Fig. 5) , and the differential L1-RSRP is quantized to a X2-bit value. The differential L1-RSRP value is computed with Y2 dB step size with a reference to the Top-1 L1-RSRP value which is a part of the same L1-RSRP reporting instance. The differential L1-RSRP value therefore represents a difference between the respective L1-RSRP and the Top-1 L1-RSRP. Additionally, a 1-bit amplitude indicator with value of 1 or 0 is associated with each L1-RSRP, to indicate the corresponding L1-RSRP is a measured L1-RSRP or a predicted L1-RSRP, or to indicate the corresponding L1-RSRP is a predicted L1-RSRP or a measured L1-RSRP, respectively. As an example, X1=7, Y1=1, X2=4, Y2=2, and the pre-defined range is [-140, -44] dBm.
[0078] Different Bit Widths and / or Step Sizes for Measured L-RSRP
[0079] According to some embodiments, settings used to convert the original RSRP to the to-be-reported RSRP value can be different respectively for measured RSRPs and predicted RSRPs. For example, the mapping as shown in Table 1 and / or Table 2 for mapping the RSRP to the to-be-reported RSRP value can be different for measured RSRPs and the predicted RSRP. The step size used to convert the original RSRP to the value for reporting may be different. Also, the bit widths of the reported RSRP values respectively corresponding to the measured RSRP and the predicted RSRP can be different.
[0080] For example as shown in Fig. 6, a Top-1 L1-RSRP (such as the largest value of L1-RSRP) is selected and quantized to a X3-bit value in a pre-defined range with Y3 dB step size (like the RSRP#1 in Fig. 6) . For measured L1-RSRP reporting, the corresponding differential L1-RSRP can be quantized to a X4-bit value and is computed with Y4 dB step size with a reference to the Top-1 L1-RSRP value, which is a part of the same L1-RSRP reporting instance. For predicted L1-RSRP reporting, the corresponding differential L1-RSRP is quantized to a X5-bit value and is computed with Y5 dB step size with a reference to the Top-1 L1-RSRP value, which is a part of the same L1-RSRP reporting instance. As an example, X3=7, Y3=1, X4=4, Y4=2, X5=3, Y5=2, and the pre-defined range is [-140, -44] dBm. Here, the step sizes, Y3 and Y4 respectively for the predicted and measured L1-RSRPs are different, and the bit widths X4 and X5 respectively for the predicted and measured L1-RSRPs are different. It should be noted that this approach of different bit width and / or step size for the measured and predicted RSRP can be combined with different approaches in this disclosure. For example, the various indicators disclosed in this disclosure can be used together.
[0081] According to some embodiments, the BS and the UE can have a preset resource set and the conversion setting used to generated the reported values of the L1-RSRP is selected based on whether the measured / reported CRIs or SSBRIs belong to the resource set. Also, the amplitude indicator can be provided based on whether the reported CRIs or SSBRIs belong to the resource set. In addition, the BS and the UE can determine the preset resource set is the resource set for measurement. The preset resource set can be a measured resource set whose channel characteristics have been measured.
[0082] For example as shown in Fig. 6, a Top-1 L1-RSRP (such as the largest value of L1-RSRP) is selected and quantized to a X3-bit value in a pre-defined range with Y3 dB step size (like the RSRP#1 in Fig. 6) . The CRI of the selected Top-1 L1-RSRP is belong to the measured resource set. In this case, if a CRI to be reported is from the measured resource set, the corresponding differential L1-RSRP can be quantized to a X4-bit value and can be computed with Y4 dB step size with a reference to the Top-1 L1-RSRP value, which is part of the same L1-RSRP reporting instance. Otherwise, if a CRI to be reported is not from the measured resource set, the corresponding differential L1-RSRP can be quantized to a X5-bit value and is computed with Y5 dB step size with a reference to the Top-1 L1-RSRP value; a 1-bit amplitude indicator with value of 1 or 0 is associated to indicate the amplitude of the corresponding L1-RSRP is greater or not greater than that of the Top-1 L1-RSRP, or to indicate the amplitude of the corresponding L1-RSRP is not greater than or greater than that of the Top-1 L1-RSRP, respectively. As an example, X3=7, Y3=1, X4=4, Y4=2, X5=3, Y5=2.
[0083] As an alternative example, the CRI of the selected Top-1 L1-RSRP is not belong to the measured resource set. In this case, if a CRI to be reported is not from the measured resource set, the corresponding differential L1-RSRP can be quantized to a X4-bit value and can be computed with Y4 dB step size with a reference to the Top-1 L1-RSRP value, which is part of the same L1-RSRP reporting instance. Otherwise, if a CRI to be reported is from the measured resource set, the corresponding differential L1-RSRP can be quantized to a X5-bit value and is computed with Y5 dB step size with a reference to the Top-1 L1-RSRP value; a 1-bit amplitude indicator with value of 1 or 0 is associated to indicate the amplitude of the corresponding L1-RSRP is greater or not greater than that of the Top-1 L1-RSRP, or to indicate the amplitude of the corresponding L1-RSRP is not greater than or greater than that of the Top-1 L1-RSRP, respectively. As an example, X3=7, Y3=1, X4=4, Y4=2, X5=3, Y5=2.
[0084] CRI / SSBRI and / or Confidence information Report Approaches
[0085] According to some embodiments of this disclosure, the CSI related quantities to be reported by the UE are CRIs and confidence levels (confidence information) , or only the confidence levels. The confidence level may be obtained by inference of functional modules (such as artificial intelligence or machine learning models or functionalities) deployed at the UE side, and the confidence level represents a probability that the corresponding CRI is associated with the largest measured value of L1-RSRP.
[0086] For confidence level reporting, two or more reporting methods with different quantization bits and / or step sizes can be configured and indicated by network. Optionally, the UE is provided with a threshold for confidence level reporting, and the confidence level lower than the threshold is not expected to be reported. Besides, for the mapping order of CSI fields of one report, the CRI associated with the largest confidence level can be presented first. All CRIs to be reported are presented according to a descending order of the corresponding confidence levels.
[0087] Report of CRI and Confidence information
[0088] According to some embodiments of this disclosure as shown in Fig. 7, all confidence levels corresponding to different CRIs to be reported can be quantized to a X1-bit value in a pre-defined range with Y1 step size. As an example, X1=7, Y1=1, and the pre-defined range is [0, 100] or [0, 1] . Like Table 1, the confidence levels can be mapped from its original value to a report value for the reporting. X1 refers to the bit width of the report value after the conversion, and the step size refers to a covered range of the confidence levels of each row of the report value.
[0089] Saving Overhead by Omitting at least one CRI’s Confidence information
[0090] According to some embodiments, the plurality of pieces of confidence information are indicative of a non-reported last piece of the confidence information of a CRI or SSBRI.
[0091] According to some embodiments, the method further includes using, by the BS, the received plurality of pieces of confidence information to generate a non-reported pieces of confidence information corresponding to a reported CRI.
[0092] According to some embodiments of this disclosure as shown in Fig. 8, for all CRIs to be reported, one of the corresponding confidence levels (e.g., CRI #4’s confidence level) is not reported. The skipped confidence level, for example, can be the confidence level with the largest value, or the confidence level associated with the first reported CRI or the last reported CRI. The skipped confidence level can be derived by the other reported confidence level (s) by the BS. For example, the sum of the all confidence levels including the skipped confidence level may be a number known by 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. Therefore, the reported confidence levels are indicated of the skipped confidence level. Additionally or alternatively, the reported confidence levels corresponding to different CRIs to be reported are quantized to a X1-bit value in the pre-defined range with Y1 step size. As an example, X1=7, Y1=1, and the pre-defined range is [0, 100] or [0, 1] .
[0093] Report with Differential Value and Amplitude Indicator
[0094] According to some embodiments, the plurality of pieces of confidence information include: a first confidence information corresponding to a first confidence value; and at least one piece of second confidence information representing at least one difference between the first confidence value and a second confidence value.
[0095] According to some embodiments, reporting the plurality of pieces of confidence information includes: providing an indicator corresponding to the at least one difference to indicate where the difference is positive or negative.
[0096] According to some embodiments, receiving the plurality of pieces of confidence information includes: receiving an indicator corresponding to the at least one difference to indicate where the difference is positive or negative.
[0097] According to some embodiments, a bit width of the first confidence information may or may not the same as a bit width of the at least one piece of second confidence information plus the indicator.
[0098] The reporting approach with the differential values described above for the L1-RSRPs can be applied for the reporting of the confidence levels. According to some embodiments of this disclosure as shown in Fig. 9, a Top-1 confidence level (like probability #1 in Fig. 9) can be selected according to inference of functional modules and quantized to a X4-bit value in a pre-defined range with Y4 dB step size. The selected Top-1 confidence level may not be the largest confidence level, and the CRI associated with the Top-1 confidence level can be presented first in the CSI fields of one report.
[0099] For other confidence levels to be reported, differential based reporting method can be used. For example, for other confidence levels to be reported, the corresponding differential confidence level is quantized to a X5-bit value and is computed with Y5 dB step size with a reference to the Top-1 confidence level value, which is a part of the same reporting instance. The differential confidence level represents a difference between a respective confidence level and the Top-1 confidence level. As explained above, the difference can be calculated by subtracting the respective confidence level from the reference confidence level or by subtracting the reference confidence level from the respective confidence level. Additionally, a 1-bit amplitude indicator with a value of 1 or 0 can be associated with each differential confidence level. The amplitude indicator can indicate the amplitude of the corresponding confidence level is greater or not greater than that of the Top-1 confidence level by a value of 0 and 1 respectively, or alternative indicate the amplitude of the corresponding confidence level is not greater than or greater than that of the Top-1 confidence level respectively by the value of 0 and 1. As explained above in the application of the amplitude indicator for the report for the RSRPs with the differential values, the BS can accord to the amplitude indicator to know whether the actual confidence level, reported as the differential value, should be derive by adding the differential value or subtracting the differential value from the Top-1 confidence level value.
[0100] Location Indicator for Report of Confidence information
[0101] According to some embodiments of this disclosure, a location indicator can be introduced, which indicates at least one of a CRI or SSBRI corresponding to a largest predicted RSRP / SINR, a largest RSRP / SINR report values, or a largest piece of confidence information.
[0102] According to some embodiments of this disclosure as shown in Fig. 10, the largest value of confidence level can be selected and quantized to a X6-bit value in a pre-defined range with Y6 dB step size. The differential confidence level is quantized to a X7-bit value, and the differential confidence level value is computed with Y7 dB step size with a reference to the largest confidence level value, which is a part of the same L1-RSRP reporting instance. Additionally, a location indicator with a bit width of can be reported by the UE to the BS to indicate the location of the largest confidence level in the CSI fields of one report, where N is the number of RS resources to be reported and is the ceiling function. As shown in Fig. 10, the location indicator is set to ‘10’ to indicate that the confidence level associated with the third reported CRI is the largest confidence level.
[0103] Combination of Different Features
[0104] As repeatedly explained above, the various features of this disclosure can be combined or implemented together for reporting the CRIs, RSRP, and / or the confidence information. As an example in Fig. 11, one of the confidence levels (and the associated indicator) is not reported (corresponding to CRI#4) , such as the confidence level with the largest value, or the confidence level associated with the first reported CRI or the last reported CRI. The differential values and the amplitude indicators are implemented in Fig. 11. Also, it should be noted that the CRI in this disclosure can be replaced with a SSBRI and that the RSRP can be replaced with a SINR.
[0105] Selection of Reporting
[0106] According to some embodiments of this disclosure, the reporting includes reporting at least one of the following combinations: the RSRP / SINR report values and the plurality of pieces of confidence information; the CRIs and the RSRP / SINR report values; or the SSBRIs and the RSRP / SINR report values.
[0107] According to some embodiments of this disclosure, the reporting including reporting two of the CRIs, the SSBRIs, the RSRP / SINR report values, and the plurality of pieces of confidence information.
[0108] According to some embodiments of this disclosure, the CSI related quantities to be reported by the UE to the BS can be the CRI, L1-RSRP and confidence level, or only the L1-RSRP and confidence level. For L1-RSRP reporting, one of the L1-RSRP reporting approaches described above, their combination, or the legacy method can be used. For confidence level reporting, one of the confidence level reporting approaches described above, or their combination can be used. Additionally, the UE can be provided with a threshold for confidence level reporting. The predicted L1-RSRP associated with the confidence level lower than the threshold is not expected to be reported.
[0109] Resource Request Indicator for CSI
[0110] According to some embodiments of this disclosure, in the CSI report, a 1-bit resource request indicator with value of 1 or 0 can be associated with each reporting instance. The resource request indicator can be provided to indicate whether additional RS resource for channel measurement is requested by the UE.
[0111] Additionally, in the CSI report, each CRI to be reported can 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.
[0112] For the purpose of beam indication, the TCI state or channel (PDCCH, PDSCH, etc. ) or Reference Signal (RS) (such as NZP-CSI-RS, SSB, etc. ) can be associated with parameters or CSI related quantities of a specific CSI report, such as the latest CSI report or the CSI report at a specific time. For example, by configuring or activating the TCI state or CSI-RS / SSB resource associated with the additional indicator in a specific CSI report, the Rx beam or spatial Rx parameter can be indicated to the UE.
[0113] Sequence of the Report
[0114] The reports from the UE above group the confidence levels and the RSRPs with its associated CRI together, but the arrangement is just an example. According to other approaches, the same type of the reported items can be arranged consecutively, but within each group, the sequence may still follow the order described in this disclosure, such as in a descending order according to the RSRP or the confidence level. For example as shown in Fig. 12, the CSRs / SSBRIs #1 to #4 are consecutively arranged. Following the CSRs / SSBRIs are the RSRPs (whether or not in the differential format) , and them any possible indicators. Within each group of the RSRPs or the indicators, the sequence may follow the same sequence of the CSRs / SSBRIs. As shown in Fig. 13, the same approach applies for the report of the CSRs / SSBRIs and confidence levels.

The present 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 approaches. Based upon design preferences, the specific order or hierarchy of steps of the disclosed methods or processes can be re-arranged while remaining within the scope of the present disclosure. Thus, those of ordinary skill in the art would understand that the methods and techniques disclosed herein present various steps or acts in exemplary order (s) , and the present disclosure is not limited to the specific order or hierarchy presented unless expressly stated otherwise.
[0116] This disclosure is intended to cover any conceivable variations, uses, combination, or adaptive changes of this disclosure following the general principles of this disclosure, and includes well-known knowledge and conventional technical means in the art and undisclosed in this application.
[0117] It is to be understood that this disclosure is not limited to the precise structures or operation described above and shown in the accompanying drawings, and various modifications and changes may be made without departing from the scope of this application. The scope of this application is subject only to the appended claims.
[0118] The methods, devices, processing, circuitry, and logic described above may be implemented in many different ways and in many different combinations of hardware and software. For example, all or parts of the implementations may be circuitry that includes an instruction processor or controller, such as a Central Processing Unit (CPU) , microcontroller, or a microprocessor; or as an Application Specific Integrated Circuit (ASIC) , Programmable Logic Device (PLD) , or Field Programmable Gate Array (FPGA) ; or as circuitry that includes discrete logic or other circuit components, including analog circuit components, digital circuit components or both; or any combination thereof. The circuitry may include discrete interconnected hardware components or may be combined on a single integrated circuit die, distributed among multiple integrated circuit dies, or implemented in a Multiple Chip Module (MCM) of multiple integrated circuit dies in a common package, as examples.
[0119] Accordingly, the circuitry may store or access instructions for execution, or may implement its functionality in hardware alone. The instructions may be stored in a tangible storage medium that is other than a transitory signal, such as a flash memory, a Random Access Memory (RAM) , a Read Only Memory (ROM) , an Erasable Programmable Read Only Memory (EPROM) ; or on a magnetic or optical disc, such as a 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, may include a storage medium and instructions stored in or on the medium, and the instructions when performed by the circuitry in a device may cause the device to implement any of the processing described above or illustrated in the drawings.
[0120] The implementations may be distributed. For instance, the circuitry may include multiple distinct system components, such as multiple processors and memories, and may span multiple distributed processing systems. Parameters, databases, and other data structures may be separately stored and managed, may be incorporated into a single memory or database, may be logically and physically organized in many different ways, and may be implemented in many different ways. Example implementations include linked lists, program variables, hash tables, arrays, records (e.g., database records) , objects, and implicit storage mechanisms. Instructions may form parts (e.g., subroutines or other code sections) of a single program, may form multiple separate programs, may be distributed across multiple memories and processors, and may 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) . The library, for example, may contain shared data and one or more shared programs that include instructions that perform any of the processing described above or illustrated in the drawings, when performed by the circuitry.
[0121] In some examples, each unit, subunit, and / or module of the system may include a logical component. Each logical component may be hardware or a combination of hardware and software. For example, each logical component may include an application specific integrated circuit (ASIC) , a Field Programmable Gate Array (FPGA) , a digital logic circuit, an analog circuit, a combination of discrete circuits, gates, or any other type of hardware or combination thereof. Alternatively or in addition, each logical component may include memory hardware, such as a portion of the memory, for example, that includes instructions executable with the processor or other processors to implement one or more of the features of the logical components. When any one of the logical components includes the portion of the memory that includes instructions executable with the processor, the logical component may or may not include the processor. In some examples, each logical component may just be the portion of the memory or other physical memory that includes instructions executable with the processor or other processor to implement the features of the corresponding logical component without the logical component including any other hardware. Because each logical component includes at least some hardware even when the included hardware includes software, each logical component may be interchangeably referred to as a hardware logical component.
[0122] A second action may be said to be “in response to” a first action independent of whether the second action results directly or indirectly from the first action. The second action may occur at a substantially later time than the first action and still be in response to the first action. Similarly, the second action may be said to be in response to the first action even if intervening actions take place between the first action and the second action, and even if one or more of the intervening actions directly cause the second action to be performed. For example, a second action may be in response to a first action if the first action sets a flag and a third action later initiates the second action whenever the flag is set.
[0123] To clarify the use of and to hereby provide notice to the public, the phrases “at least one of , , …and <N>” or “at least one of , , …<N>, or combinations thereof” or “, , …and / or <N>” are defined by the Applicant in the broadest sense, superseding any other implied definitions hereinbefore or hereinafter unless expressly asserted by the Applicant to the contrary, to mean one or more elements selected from the group comprising A, B, …and N. In other words, the phrases mean any combination of one or more of the elements A, B, …or N including any one element alone or the one element in combination with one or more of the other elements which may also include, in combination, additional elements not listed.
