[0050] As discussed above, the terminal device and the network device may use different ML models to assist communication-related functionalities, such as, BM, mobility management and so on.
[0051] So far, two BM cases (i.e., BM-case1 and BM-case2) have been proposed and discussed separately, specifically, ● BM-Case1: Spatial-domain downlink beam prediction for Set A of beams based on measurement results of Set B of beams; Consider: 1) : artificial intelligence (AI) / machine learning (ML) model training and inference at NW side. 2) : AI / ML model training and inference at UE side. Consider: 1) : Set A and Set B are different (Set B is not a subset of Set A) . 2) : Set B is a subset of Set A. Note: Set A is for DL beam prediction. AI / ML model input consider: 1) : only L1-reference signal receiving power (RSRP) measurement based on Set B; 2) : L1-RSRP measurement based on Set B and assistance information; 3) : channel impulse response (CIR) based on Set B; 4) : layer 1 (L1) -reference signal receiving power (RSRP) measurement based on Set B and the corresponding DL Tx and / or Rx beam ID. ● BM-Case2: Temporal Downlink beam prediction for Set A of beams based on the historic measurement results of Set B of beams; Consider: 1) : AI / ML model training and inference at NW side. 2) : AI / ML model training and inference at UE side. Consider: 1) : Set A and Set B are different (Set B is NOT a subset of Set A) . 2) : Set B is a subset of Set A (Set A and Set B are not the same) . 3) : Set A and Set B are the same. AI / ML model input consider: measurement results of K (K≥1) latest measurement instances with the following alternatives: 1) : Only L1-RSRP measurement based on Set B; 2) : L1-RSRP measurement based on Set B and assistance information; 3) : L1-RSRP measurement based on Set B and the corresponding DL Tx and / or Rx beam ID. F predictions for F future time instances can be obtained based on the output of AI / ML model, where each prediction is for each time instance. At least F=1.
[0052] Set B is a set of beams whose measurements may be taken as inputs of the AI / ML model.
[0053] One objective on AI / ML is Provide specification support for beam management -DL Tx beam prediction for both UE-sided model and NW-sided model, encompassing: spatial-domain DL Tx beam prediction for Set A of beams based on measurement results of Set B of beams ( “BM-Case1” ) ; temporal DL Tx beam prediction for Set A of beams based on the historic measurement results of Set B of beams ( “BM-Case2” ) ; specifying necessary signalling / mechanism (s) to facilitate LCM operations specific to the beam management use cases, if any; enabling method (s) to ensure consistency between training and inference regarding NW-side additional conditions (if identified) for inference at UE.
[0054] For BM-Case1 and BM-Case2 with a UE-side AI / ML model, Type 1 performance monitoring and Type 2 performance monitoring may be supported. As for Type 1 performance monitoring, configuration / Signalling may be transmitted from gNB to UE for measurement and / or reporting. Further, UE may have different operations as below: Option 1 (NW-side performance monitoring) : UE sends reporting to NW (e.g., for the calculation of performance metric at NW) ; and Option 2 (UE-assisted performance monitoring) : UE calculates performance metric (s) , either reports it to NW or reports an event to NW based on the performance metric (s) .
[0055] Indication may be transmitted from NW for UE to do life cycle management (LCM) operations. Further, at least the performance and reporting overhead of model monitoring mechanism should be considered.
[0056] As for Type 2 performance monitoring, indication / request / report may be transmitted from UE to gNB for performance monitoring. It is noted that the indication / request / report may be not needed in some case (s) . Configuration / Signalling from gNB to UE for performance monitoring measurement and / or reporting. Further, if it is for UE side model monitoring, UE makes decision (s) of model selection / activation / deactivation / switching / fallback operation. Mechanism that facilitates the UE to detect whether the functionality / model may be suitable or no longer suitable.
[0057] For BM-Case1 and BM-Case2 with a NW-side AI / ML model, in a case that beam measurement and report for model monitoring: UE reporting of beam measurement (s) may be based on a set of beams indicated by gNB; signalling may be e.g., RRC-based, L1-based. Further, NW monitors the performance metric (s) and makes decision (s) of model selection / activation / deactivation / switching / fallback operation. Performance and UE complexity, power consumption should be considered.
[0058] Beam prediction accuracy related key performance indicators (KPIs) , may include: - Top-1 genie-aided Tx beam considers the following definitions: - Option A, the Top-1 genie-aided Tx beam is the Tx beam that results in the largest layer 1 (L1) -reference signal received power (RSRP) over all Tx and Rx beams; - Option B, the Top-1 genie-aided Tx beam is the Tx beam that results in the largest L1-RSRP over all Tx beams with specific Rx beam (s) ; Specific Rx beam (s) are to be reported. Note: specific Rx beams are a subset of all Rx beams. - Top-1 genie-aided Tx-Rx beam pair considers the following definitions: - Option A: The Tx-Rx beam pair that results in the largest L1-RSRP over all Tx and Rx beams; - Other options not precluded and can be reported; - Average L1-RSRP difference of Top-1 predicted beam: - The difference between the ideal L1-RSRP of Top-1 predicted beam and the ideal L1-RSRP of the Top-1 genie-aided beam; - Beam prediction accuracy (%) : - Top-1 (%) : the percentage of "the Top-1 genie-aided beam is Top-1 predicted beam" ; - Top-K / 1 (%) : the percentage of "the Top-1 genie-aided beam is one of the Top-K predicted beams" ; - Top-1 / K (%) (Optional) : the percentage of "the Top-1 predicted beam is one of the Top-K genie-aided beams" ; - Where K >1 and values can be reported; - cumulative distribution function (CDF) of L1-RSRP difference for Top-1 predicted beam; - Beam prediction accuracy (%) with 1dB margin for Top-1 beam; - The beam prediction accuracy (%) with 1dB margin is the percentage of the Top-1 predicted beam "whose ideal L1-RSRP is within 1dB of the ideal L1-RSRP of the Top-1 genie-aided beam" ; - Other beam prediction accuracy related KPIs are not precluded and can be reported.
[0059] It has been agreed that for UE-sided model, at least for BM-Case1, for content in the report of inference results, support: - Option 1: Beam information on predicted Top K beam (s) among a set of beams (K=1 or larger) ; - Option 2: Beam information on predicted Top K beam (s) among a set of beams and RSRP of predicted Top K beam (s) among a set of beams (K=1 or larger) ; - Option 3: Beam information on predicted Top K beam (s) among a set of beams and probability information of predicted Top K beam (s) among a set of beams; Probability information is the probability of the beam to be the Top 1 or Top K beam; -Option 4: Beam information on predicted Top K beam (s) among a set of beams, RSRP of predicted Top K beam (s) among a set of beams, and confidence information of the RSRP, where the set of beams is Set A, i.e., the beams for UE prediction.

[0109] Principles and implementations of the present disclosure will be described in detail below with reference to the figures.Example environment
[0110] FIG. 1 illustrates a schematic diagram of an example communication environment 100 in which example embodiments of the present disclosure can be implemented. In the communication environment 100, a plurality of communication devices, including a first device 110 and a second device 120, can communicate with each other.
[0111] Further, multiple input multiple output (MIMO) is supported in the communication environment 100, such that the second device 120 and the first device 110 may communicate with each other via different beams to enable a directional communication.
[0112] In FIG. 1, the first device 110 / second device 120 may be included a terminal device, gNB, a network device, an over the top (OTT, server) , a CN, an edge cloud (server) , a neutral site, AP, transmission reception point (TRP) and so on.
[0113] As one example scenario, the first device 110 may include a terminal device and the second device 120 may include a network device serving the terminal device. In this specific example embodiment, a direction from the first device 110 to the second device 120 is referred to as uplink, while a direction from the second device 120 to the first device 110 is referred to as a downlink.
[0114] In downlink, the second device 120 is a transmitting (TX) device (or a transmitter) and the first device 110 is a receiving (RX) device (or a receiver) , and the second device 120 may transmit downlink transmission to the first device 110 via one or more beams. As illustrated in FIG. 1, the second device 120 transmits downlink transmission to the first device 110 via the beams 140-1 to 140-3. For purpose of discussion, the beams 140-1 to 140-3 are collectively or individually referred to as beam 140.
[0115] Correspondingly, in uplink, the second device 120 is an RX device (or a receiver) and the first device 110 is a TX device (or a transmitter) , and the first device 110 may transmit uplink transmission to the second device 120 via one or more beams. As illustrated in FIG. 1, the first device 110 transmits uplink transmission to the second device 120 via the beams 130-1 to 130-3. For purpose of discussion, the beams 130-1 to 130-3 are collectively or individually referred to as beam 130.
[0116] Further, in some embodiments, a model 115 may be deployed at the first device 110 and / or a model 125 may be deployed at the second device 120.
[0117] It is to be understood that the number of devices and their connections shown in FIG. 1 are only for the purpose of illustration without suggesting any limitation. The communication environment 100 may include any suitable number of devices configured to implementing example embodiments of the present disclosure.
[0118] In some embodiments, the first device 110 and the second device 120 may communicate with each other via a channel such as a wireless communication channel on an air interface (e.g., Uu interface) .

Of course, any other suitable channels are also feasible.
[0119] The communications in the communication environment 100 may conform to any suitable standards including, but not limited to, Global System for Mobile Communications (GSM) , Long Term Evolution (LTE) , LTE-Evolution, LTE-Advanced (LTE-A) , New Radio (NR) , Wideband Code Division Multiple Access (WCDMA) , Code Division Multiple Access (CDMA) , GSM EDGE Radio Access Network (GERAN) , Machine Type Communication (MTC) and the like.

[0120] For UE-sided model, when the performance corresponding to the model deteriorates, i.e., the performance monitoring results is not good (or below a threshold) , the inference results of the model is inaccurate / unacceptable. In order to avoid unnecessary beam measurement and reporting, the CSI report (s) for inference may be stopped (e.g., periodic (P) CSI report for inference may be released, semi-persistent (SP) CSI report for inference may be deactivated) by NW. However, in this case, considering the following reasons, performance monitoring may still need to be performed, specifically, the CSI report (s) for monitoring may still need to be performed. The real environment is ever-changing and unpredictable. The current performance monitoring results may only reflect that the current model cannot adapt to the current environment, which means that, whether the current model may adapt to future environment still needs to be based on subsequent (continuous) performance monitoring. When the performance deteriorates, model switching, selection or update may be considered, e.g., switching to (or training) a new model different from the current model. But before the new model is applied in model inference, it is necessary to ensure that the new model may predict accurate results. Therefore, performance monitoring is needed. Other reasons depending on NW also may cause the performance monitoring being needed.
[0121] For the CSI report for monitoring, the determination of the reported performance monitoring results needs to be based on the inference results determined based on the CSI report for inference associated with (or linked to) the CSI report for monitoring. However, as mentioned above, in a case that the CSI report for inference is stopped by NW, UE may be unable to obtain the inference results, resulting in performance monitoring (i.e., CSI report for monitoring) being unable to be performed. According to some embodiments of the present disclosure, the performance monitoring (i.e., CSI report for monitoring) may be performed properly.
[0122] Reference is made to FIG. 2, which illustrates a signaling flow 200 for communication in accordance with some embodiments of the present disclosure. For the purposes of discussion, the signaling flow 200 will be discussed with reference to FIG. 1, for example, by using the first device 110 and the second device 120.
[0123] It is to be understood that the operations at the first device 110 and the second device 120 should be coordinated. In other words, the second device 120 and the first device 110 should have common understanding about configurations, parameters and so on. Such common understanding may be implemented by any suitable interactions between the second device 120 and the first device 110 or both the second device 120 and the first device 110 applying the same rule / policy. In the following, although some operations are described from a perspective of the first device 110, it is to be understood that the corresponding operations should be performed by the second device 120. Similarly, although some operations are described from a perspective of the second device 120, it is to be understood that the corresponding operations should be performed by the first device 110. Merely for brevity, some of the same or similar contents are omitted here.
[0124] For the purpose of discussion, the first device 110 may be a terminal device and the second device 120 may be a network device.

[0126] As illustrated in FIG. 2, in operation, the second device 120 may transmit (210-1) at least one configuration associated with one or more CSI reports to the first device 110, and first device 110 may receive (210-2) the at least one configuration accordingly. In one example, the at least one configuration may be associated with one CSI report, such as, a first CSI report or a second CSI report, for inference and / or performance monitoring. In another example, the at least one configuration may be associated with two CSI reports, such as, a first CST report and a second CSI report. In a further example, the at least one configuration may be associated with multiple CSI reports.
[0127] Based on the at least one configuration, the first device 110 performs (220) measurement and / or reporting associated with a first CSI report for a first ML phase (such as, an inference phase) , where the first CSI report is associated with a second CSI report for a second ML phase (such as, a performance monitoring phase) .

Alternatively, or in addition, in some other embodiments, the at least one first indication may comprise an indication indicating the first device 110 to stop or continue the measurement and reporting associated with the first CSI report (in other words, to stop or continue the first CSI report) .
[0131] In some other embodiments, the at least one first command may indicate at least one parameter to be used by the first device 110 to perform measurement and / or reporting associated with the first CSI report (and / or second CSI report) after receiving the at least one first command.

[0135] Alternatively, or in addition, in some other embodiments, the at least one parameter may comprise an indication of whether the second periodicity is determined based on a first periodicity associated with the first CSI report and / or a relationship between the first periodicity and the second periodicity.
[0136] As illustrated in FIG. 2, after receiving the at least one first command, the first device 110 performs (240) the measurement and / or reporting associated with the first CSI report based at least in part on the at least one first command. In this way, when the first device 110 performs inference and performance monitoring and the inference-related procedure is indicated to be stopped, the performance monitoring which is based on the inference may still be proceed properly.

The CSI report (s) may be CSI reports for inference and / or performance monitoring.
[0141] Generally speaking, performing reporting associated with the first CSI reports means that the related measurement (s) associated with the first CSI reports is also needed to be performed.

In this event, the at least one first command may indicate an identity of a periodicity of the plurality of periodicities, and the first device 110 may perform, the measurement and / or reporting associated with the first CSI report based on the periodicity indicated by the at least one first command.

[0157] According to some embodiments of the present disclosure, when receiving a first command for stopping the first CSI report, if there is other related report (s) associated with first CSI report, the processes on the other related report (s) may be improved. Example embodiments will be discussed in the following.
[0158] In operation, the first device 110 may perform measurement and / or reporting associated with a first CSI report, where the first CSI report is associated with a second CSI report. Then the first device 110 may receive at least one first command for stopping the first CSI report from a second device 120. In some embodiments, the first device 110 may stop the second CSI report. As one example, if the CSI report for performance monitoring is associated with a CSI report for inference, when the CSI report for inference is stopped, the CSI report for performance monitoring is also stopped.
[0159] In some embodiments, the first device 110 may stop the second CSI report in accordance with at least one of the following: the at least one first measurement resource being not a subset of the at least one second measurement resource, the at least one first measurement resource being different from the at least one second measurement resource, or the at least one first measurement resource not overlapping with the at least one second measurement resource.
[0160] Alternatively, in some embodiments, the first device 110 may perform measurement and inference based on: at least one first measurement resource and at least one first prediction resource associated with the first CSI report (such as, for inference) , and at least one second measurement resource associated with the second CSI report (such as, for performance monitoring) . As one example, if the CSI report for performance monitoring is associated with a CSI report for inference, when the CSI report for inference is stopped, the first device 110 continue to obtain inference results based on the configuration associated with the CSI report for inference.
[0161] In some embodiments, the first device 110 may perform the measurement and inference based on at least one first measurement resource and at least one first prediction resource associated with the first CSI report and at least one second measurement resource associated with the second CSI report, in accordance with at least one of the following: the at least one first measurement resource being a subset of the at least one second measurement resource, the at least one first measurement resource being the same as the at least one second measurement resource, or the at least one first measurement resource overlapping with the at least one second measurement resource.
[0162] According to some embodiments of the present disclosure, more than one sub-configuration may be defined, and the sub-configuration may be applied based on suitable conditions.
[0163] In operation, the first device 110 may receive at least one configuration associated with a first CSI report (such as, for performance monitoring) from a second device 120, where the at least one configuration may comprise a first sub-configuration and a second sub-configuration.
[0164] In some embodiments, the first device 110 may apply the first sub-configuration in accordance with a determination that the first CSI report is associated with a second CSI report and the second CSI report is triggered by the second device 120. Alternatively, in some embodiments, the first device 110 may apply the second sub-configuration in accordance with one of the following: the first CSI report being associated with a second CSI report and the second CSI report being stopped, or the first CSI report being not associated with a second CSI report.
[0165] According to some embodiments of the present disclosure, the first device 110 may receive configuration information associated with a CSI report. However, in order to obtain information for the CSI report, other configuration information is needed. For example, when receiving configuration information associated with a CSI report for performance monitoring. In order to obtain performance monitoring, inference-related information is also needed. Example embodiments for this specific scenario will be discussed.
[0166] In operation, the first device 110 may receive at least one configuration associated with a first CSI report for a first ML phase from a second device 120, where the at least one configuration comprises at least one measurement resource. In this event, the first device 110 may determine at least one prediction resource associated with the first CSI report based on the at least one measurement resource, if at least one of the following: the first CSI report being not associated with a second CSI report for a second ML phase; receiving first information from the second device 120, wherein the first information indicates that the at least one measurement resource is the same as the at least one prediction resource; or receiving second information from the second device 120, wherein the second information indicates the first device 110 to perform measurement and inference for the first CSI report.
[0167] In some embodiments, for a CSI report, if the CSI report is not associated with a prediction resource set, the first device 110 may determine the prediction resource set based on a measurement resource set associated with the CSI report.
[0168] Additionally, in some embodiments, if the first device 110 receives a command or information (associated with the CSI report) indicating Set B (i.e., measurement resource set) is the same as Set A (i.e., prediction resource set) , or Set B is a subset of Set A, or Set B is determined based on Set A, the first device 110 may determine the prediction resource set based on a measurement resource set associated with the CSI report.
[0169] According to some embodiments of the present disclosure, some configuration limitation may be defined. Specifically, in some embodiments, the first device 110 may receive, from a second device 120, at least one configuration associated with a first CSI report. In some embodiments, the first device 110 may expect the first CSI report being associated with a triggered second CSI report. Alternatively, in some embodiments, the first device 110 does not expect a triggered second CSI report associated with the first CSI report to be stopped. Alternatively, in some embodiments, the first device 110 does not expect a periodicity of first CSI report being smaller than a periodicity of a second CSI report associated with the first CSI report. That is, the second device 110 is required to avoid making such configuration.
[0170] For a better understanding about the above processes, more example embodiments will be discussed, It should be noted that below example embodiments should not be considered as any limitation of the present discourse.
[0171] According to some embodiments of the present disclosure, in order to ensure the performance monitoring may be transmitted to the NW, in some embodiments, the measurement and reporting for inference CSI report may not be stopped completely. Such example embodiments will be discussed in the following.
[0172] In operation, for a triggered CSI report for inference (represented as ‘inference CSI report’ , e.g., P CSI report, SP CSI report based on PUCCH, SP CSI report based on PUSCH) , UE may receive a first command from the NW. In some embodiments, the first command may comprise at least one of the following: a command (e.g., MAC CE) that deactivates the triggered inference CSI report (e.g., activated SP inference CSI report based on PUCCH) ; a command (e.g., DCI) that deactivates the triggered inference CSI report (e.g., activated SP inference CSI report based on PUSCH) ; and / or a command (which may be a newly-defined L1 / L2 / L3 command) that indicates to stop the triggered inference CSI report (e.g., configured P inference CSI report, activated SP inference CSI report) .
[0173] In some embodiments, the first command may comprise at least one of the following information: ID of CSI report, for example, CSI-ReportConfigId associated with the inference CSI report indicated by the first command; ID of trigger state; for example, ID associated with a SP or AP CSI trigger state associated with the inference CSI report indicated by the first command; an indication of whether measurement is stopped (or continued) for the inference CSI report indicated by the first command; an indication of whether reporting is stopped (or continued) for the inference CSI report indicated by the first command; and / or an indication of whether both measurement and reporting are stopped (or continued) for the inference CSI report indicated by the first command.
[0174] Upon (or after) receiving the first command, if the triggered CSI report for inference is not associated with (or linked to) at least one triggered CSI report for monitoring (represented by ‘monitoring CSI report’ ) , UE may stop measurement and reporting for the triggered inference CSI report., if the triggered CSI report for inference is associated with (or linked to) at least one triggered CSI report for monitoring (represented by ‘monitoring CSI report’ ) , at least one of the following UE behaviors may be considered.
[0175] In some embodiments (referred to as option 1) , if the first command indicates measurement is not stopped and / or reporting is stopped (if the corresponding indication (s) exist) , UE may only perform measurement for the triggered inference CSI report (in other words, UE may only stop reporting for the triggered inference CSI report) . Reference is now made to FIG. 3A. As illustrated, after receiving the first command, the measurement associated with the first CSI report is continued while the reporting associated with the first CSI report is stopped.
[0176] Additionally, in some embodiments, UE may only perform measurement for the triggered inference CSI report at a reporting instance (corresponding to the triggered inference CSI report) satisfying at least one of the following: the reporting instance is closest to a further reporting instance corresponding to a triggered monitoring CSI report associated with the inference CSI report, where the reporting instance may be before or after the further reporting instance; and / or Time interval between the reporting instance and a further reporting instance corresponding to a triggered monitoring CSI report associated with the inference CSI report is smaller than or equal to a threshold.
[0177] Reference is now made to FIG. 3B. In the example of FIG. 3B, after receiving the first command, the measurements at time instance #1 and time instance #2 are performed and measurements at other instances are stopped.
[0178] In some embodiments, if the first command indicates measurement is not stopped and / or reporting is not stopped (if the corresponding indication (s) exist) , UE may perform measurement and reporting for the triggered inference CSI report at a reporting instance (corresponding to the triggered inference CSI report) satisfying at least one of the following: the reporting instance is closest to a further reporting instance corresponding to a triggered monitoring CSI report associated with the inference CSI report, where the reporting instance may be before or after the further reporting instance; and / or Time interval between the reporting instance and a further reporting instance corresponding to a triggered monitoring CSI report associated with the inference CSI report is smaller than or equal to a threshold.
[0179] Reference is now made to FIG. 3C. In the example of FIG. 3C, after receiving the first command, the measurements and reporting at time instance #1 and time instance #2 are performed and measurements at other instances are stopped.
[0180] In some embodiments (referred to as option 2) , if the first command indicates measurement is not stopped and / or reporting is not stopped (if the corresponding indication (s) exist) , UE may perform measurement and reporting for the triggered inference CSI report based on a new periodicity (referred to as the second periodicity, e.g., larger periodicity than the previous periodicity which is referred to as the first periodicity) determined based on the periodicity of the triggered monitoring CSI report (referred to as the third periodicity) associated with the inference CSI report.
[0181] Reference is now made to FIG. 3C. In the example of FIG. 3C, the new periodicity of the inference CSI report is equal to the periodicity of the monitoring CSI report. Specifically, the frame and slot number (within the frame) where UE transmits the inference CSI report may be determined based on the periodicity of the triggered monitoring CSI report associated with the inference CSI report.
[0182] Optionally, if the first command indicates measurement is not stopped and / or reporting is stopped (if the corresponding indication (s) exist) , UE may only perform measurement (in other words, UE may only stop reporting) for the triggered inference CSI report based on the new periodicity determined based on the periodicity of the triggered monitoring CSI report.
[0183] In some embodiments, when the performance monitoring results is good / better / acceptable again, the inference CSI report may be performed normally again. Specifically, for the triggered CSI report for inference, when (or after) UE receives at least one of the following commands (represented by ‘second command’ ) : a command (e.g., MAC CE) that activates the inference CSI report (e.g., the deactivated SP inference CSI report based on PUCCH) ; a command (e.g., DCI) that activates the inference CSI report (e.g., the deactivated SP inference CSI report based on PUSCH) or a command (maybe a new L1 / L2 / L3 command) that indicates to (re) start the triggered inference CSI report (e.g., configured P inference CSI report, activated SP inference CSI report) .
[0184] In some embodiments, the second command may comprise at least one of the following information: ID of CSI report. E.g., CSI-ReportConfigId associated with the inference CSI report indicated by the second command; ID of trigger state. E.g., ID associated with a SP or AP CSI trigger state associated with the inference CSI report indicated by the second command; an indication of whether measurement is stopped (or continued) for the inference CSI report indicated by the second command; an indication of whether reporting is stopped (or continued) for the inference CSI report indicated by the second command; and an indication of whether both measurement and reporting are stopped (or continued) for the inference CSI report indicated by the second command.
[0185] In operation, UE may (start or restart to) perform measurement and reporting for the triggered inference CSI report. Reference is now made to FIG. 3D. In the example of FIG. 3D, after receiving the second command, the UE starts or restarts to perform measurement and reporting for the triggered inference CSI report.
[0186] In some embodiments, for the triggered CSI report for inference, when (or after) UE receives a command (represented by ‘first command’ ) that indicates to update the periodicity of the triggered inference CSI report.
[0187] In some embodiments, the first command may comprise at least one of the following information: ID of CSI report. E.g., CSI-ReportConfigId associated with the inference CSI report indicated by the first command; ID of trigger state. E.g., ID associated with a SP or AP CSI trigger state associated with the inference CSI report indicated by the first command; a new periodicity (referred to as the second periodicity) , which may be the same as or different from the configured periodicity associated with the inference CSI report indicated by the first command (represented by ‘old periodicity’ ) ; an indication of whether a new periodicity is applied for the inference CSI report indicated by the first command, i.e., whether the indicated new periodicity or the old periodicity is applied; an indication of whether the periodicity of the inference CSI report indicated by the first command is determined based on the periodicity of the monitoring CSI report associated with the inference CSI report indicated by the first command.
[0188] In some embodiments, if at least one of the following is fulfilled, UE may perform measurement and reporting for the indicated inference CSI report based on the indicated new periodicity: - The first command indicates a new periodicity (and it is different from the old periodicity) . - The first command indicates a new periodicity is applied for the indicated inference CSI report. - The indicated inference CSI report is not associated with at least one (triggered) monitoring CSI report. - The first command indicates the periodicity of the indicated inference CSI report is determined based on the periodicity of the monitoring CSI report associated with the indicated inference CSI report.
[0189] In some embodiments, UE may perform measurement and reporting for the indicated inference CSI report based on the periodicity of a (triggered) monitoring CSI report associated with the indicated CSI report if at least one of the following is fulfilled: no periodicity is indicated by the first command; the first command indicates a new periodicity is applied for the indicated inference CSI report; the indicated inference CSI report is associated with at least one (triggered) monitoring CSI report, and / or the first command indicates the periodicity of the indicated inference CSI report is determined based on the periodicity of the monitoring CSI report associated with the indicated inference CSI report.
[0190] In some embodiments, an inference CSI report may be associated with multiple periodicities, e.g., 2 periodicities. The 2 periodicities may be reporting (or inference) periodicity (e.g., the smallest periodicity) and monitoring periodicity (e.g., the largest monitoring periodicity) respectively.
[0191] In some embodiments, for a triggered inference CSI report, when (or after) UE receives a command (represented by ‘first command’ ) that indicates to update the periodicity of the triggered inference CSI report. In some embodiments, the first command may comprise at least one of the following information: - ID of CSI report. E.g., CSI-ReportConfigId associated with the inference CSI report indicated by the first command; - ID of trigger state. E.g., ID associated with a SP or AP CSI trigger state associated with the inference CSI report indicated by the first command; - ID of periodicity, which indicates one of the multiple periodicities associated with the inference CSI report indicated by the first command. In other words, it indicates which periodicity is applied.
[0192] In some embodiments, if the first command indicates a periodicity (and it is different from the old periodicity) , UE may perform measurement and reporting for the indicated inference CSI report based on the indicated periodicity.
[0193] In some embodiments, for a triggered inference CSI report, before UE receives the first command, UE may perform measurement and reporting for the smallest periodicity or the reporting (or inference) periodicity.
[0194] In some embodiments, for a triggered inference CSI report, if it is associated with no monitoring periodicity, and / or if it is associated with at least one (triggered) monitoring CSI report, UE may determine the monitoring periodicity based on the periodicity of a (triggered) monitoring CSI report associated with the inference CSI report. Furthermore, if it is associated with more than one monitoring CSI report, the monitoring periodicity is determined based on the smallest periodicity of the monitoring CSI reports.
[0195] Considering that the periodicity of the monitoring CSI report may be updated, for a triggered monitoring CSI report and / or a triggered inference CSI report, when (or after) UE receives a command (represented by ‘first command’ ) indicates to update the periodicity of the triggered monitoring CSI report and / or the triggered inference CSI report. In some embodiments, the first command may comprise at least one of the following information: - ID of CSI report. E.g., CSI-ReportConfigId associated with the inference or monitoring CSI report indicated by the first command; - ID of trigger state. E.g., ID associated with a SP or AP CSI trigger state associated with the inference or monitoring CSI report indicated by the first command; - Periodicity; - ID of periodicity. Specifically, the monitoring CSI report or inference CSI report is associated with multiple periodicities configured by NW. And the ID of periodicity indicates one of the multiple configured periodicities.
[0196] In some embodiments, UE may apply the first command (i.e., the periodicity indicated by the first command) to at least one of the following: - the monitoring CSI report indicated by the first command and the inference CSI report indicated by the first command (if the first command indicates ID of the inference CSI report and the monitoring CSI report) . - the monitoring CSI report indicated by the first command, and optionally, an inference CSI report associated with the indicated monitoring CSI report (if the first command only indicates ID of the monitoring CSI report) . - the inference CSI report indicated by the first command, and optionally, a monitoring CSI report associated with the indicated inference CSI report (if the first command indicates ID of the inference CSI report) .
[0197] Reference is now made to FIG. 3E. As illustrated in FIG. 3E, when the performance monitoring results is good again, the monitoring CSI report and / or the inference CSI report may be performed normally again. Specifically, for the triggered monitoring CSI report and / or the triggered inference CSI report, optionally, NW may send a further first command to UE to update the periodicity of the monitoring CSI report and / or the inference CSI report. In this case, the first command may indicate 2 periodicities, one is applied for the monitoring CSI report and the other one is applied for the inference CSI report.
[0198] Additionally, in some embodiments, the first command may also comprise at least one of the following, and UE may only perform measurement based on the information indicated by the received first command: - an indication of whether measurement is stopped (or continued) for the inference CSI report indicated by the first command; - an indication of whether reporting is stopped (or continued) for the inference CSI report indicated by the first command; - an indication of whether both measurement and reporting are stopped (or continued) for the inference CSI report indicated by the first command.
[0199] In some embodiments, when the performance monitoring results is good again, the inference CSI report may be performed normally again. Specifically, for the triggered CSI report for inference, optionally, NW may send a further first command to UE to update the periodicity of the indicated inference CSI report, e.g., updating to the old periodicity or another (smaller) periodicity (based on NW implementation) .
[0200] In some embodiments, when the performance monitoring results is not good, optionally, NW may send a first command to UE to deactivate (AI / ML) functionality, or / and deactivate LCM procedure (e.g., model inference, performance monitoring) related to AI / ML, or / and deactivate CSI report (s) for LCM procedure related to AI / ML. Specifically, at least one first command may be used to indicate activation (or enable) or deactivation (or disable) of one or more CSI report for one or more LCM procedure related to AI / ML.
[0201] In some embodiments, the first command may comprise an activation or deactivation indication. Alternatively, or in addition, in some embodiments, the first command may comprise ID of CSI trigger state, and / or ID of CSI report. Optionally, if ID of CSI report is absent, the first command may be applied for all (triggered) CSI reports (related to AI / ML) .
[0202] Alternatively, or in addition, in some embodiments, the first command may comprise information about a time domain type of CSI report. Optionally, if the time domain type of CSI report is absent, the first command may be applied for all (triggered) CSI reports or a specified time domain type of CSI report.
[0203] Alternatively, or in addition, in some embodiments, the first command may comprise information about an LCM type of CSI report. This information may indicate an LCM type (e.g., model inference, performance monitoring) or an indicator of LCM type. Optionally, this information may indicate a report quantity of CSI report (e.g., predicted CSI, indicator about performance metric) or an indicator of report quantity of CSI report. For example, if the first command indicates deactivation and report quantity ‘predicted CSI’ , UE may stop CSI report (s) configured for reporting ‘predicted CSI’ . Optionally, if this information is absent, the first command may be applied for all (triggered) CSI reports or a specified LCM type of CSI report.
[0204] Alternatively, or in addition, in some embodiments, the first command may comprise an associated ID. For example, if the first command indicates deactivation and ‘associated ID = 2’ , UE may stop CSI report (s) associated with ‘associated ID = 2’ . Optionally, if the associated ID is absent, the first command may be applied for all (triggered) CSI reports or a specified associated ID.
[0205] Alternatively, or in addition, in some embodiments, the first command may comprise an indication of whether measurement or / and reporting is stopped (or continued) . Optionally, if this information is absent, UE may stop measurement and reporting, only stop reporting and only stop measurement. In some embodiments, this indication may be specific for ID of CSI report, time domain type of CSI report, LCM type of LCM report, associated ID.
[0206] Alternatively, or in addition, in some embodiments, the first command may comprise information about a time window (unit: symbol / slot / sub-frame / frame / ms / s) . Specifically, within the time window, UE may stop all (triggered) CSI reports (related to AI / ML) , and optionally, UE may ignore any signaling triggering CSI report (related to AI / ML) . In some embodiments, a starting location or reference location of the time window may be a timing of successfully receiving the first command, e.g., the first time unit after PUCCH / PUSCH carrying HARQ-ACK information corresponding to PDSCH carrying the first command (if it is a MAC CE) , or after PDCCH carrying the first command (if it is a DCI) . In some embodiments, this formation may be specific for ID of CSI report, time domain type of CSI report, LCM type of LCM report, associated ID. It should be noted that information about time window may be included in the first command and used with any suitable parameter in a combination manner.
[0207] Alternatively, or in addition, in some embodiments, the first command may comprise information about a new periodicity as discussed above. In some embodiments, the new periodicity may be specific for ID of CSI report, time domain type of CSI report, LCM type of LCM report, associated ID.
[0208] In some embodiments, when the performance monitoring results is good again, the at least one first command may indicate an activation indication. Optionally, the at least one first command may be used to indicate activation (or enable) or deactivation (or disable) of one or more CSI report for one or more LCM procedure related to AI / ML (i.e., CSI report related to AI / ML) , or / and one or more CSI report related to non-AI / ML (e.g., CSI report is configured for reporting measured CSI) .
[0209] In some embodiments, in order to ensure the performance monitoring may be performed properly, some configuration limitations may be defined. Specifically, in some embodiments, for a (triggered) monitoring CSI report, UE does not expect at least one of the following: a (triggered) inference CSI report associated with the monitoring CSI report is stopped; and / or a periodicity of a (triggered) inference CSI report associated with the monitoring CSI report is larger than a periodicity of the monitoring CSI report.
[0210] In some embodiments, NW may trigger (or reconfigure) an inference CSI report, which is associated with a monitoring CSI report. In some embodiments, the CSI report is configured for reporting nothing (i.e., report quantity may be ‘none’ ) to reduce unnecessary reporting overhead. In this case, in order to ensure UE determines if the predicted CSI needs to be calculated for the CSI report, some other assistant information may be used by the UE to determine the reporting information as discussed below.
[0211] In some embodiments, for a CSI report, UE may determine what information (e.g., whether predicted CSI or measured CSI) needed to be calculated (or determined) (in other words, UE may determine whether the CSI report is an inference CSI report) based on the number of CSI resources (e.g., CSI-ResourceConfigId) associated with the CSI report. For example, when the number is equal to 2, UE may need to determine predicted CSI (e.g., predicted CRI / SSBRI, RSRP or / and probability) for the CSI report. When the number is equal to 1, UE may need to determine measured CSI (e.g., measured beam, measured RSRP) .
[0212] Alternatively, or in addition, in some embodiments, for a CSI report, UE may determine whether the CSI report is an inference CSI report based on an associated ID associated with the CSI report. For example, if the CSI report is associated with at least one associated ID, UE may need to determine predicted CSI; otherwise, UE may need to determine measured CSI.
[0213] Alternatively, or in addition, in some embodiments, for a CSI report, UE may determine whether the CSI report is an inference CSI report based on whether the monitoring CSI report associated with the CSI report. For example, if the CSI report is associated with at least one monitoring CSI report, UE may need to determine predicted CSI; otherwise, UE may need to determine measured CSI.
[0214] Alternatively, or in addition, in some embodiments, for a CSI report, UE may determine whether the CSI report is an inference CSI report based on the measurement (or observation) window or / and prediction window associated with the CSI report. For example, in case of BM-Case 2, if the CSI report is associated with a measurement window or / and prediction window, UE may need to determine predicted CSI; otherwise, UE may need to determine measured CSI.
[0215] Alternatively, or in addition, in some embodiments, for a CSI report, UE may determine whether the CSI report is an inference CSI report based on whether the CSI report is included in a set of applicable CSI reports reported by UE (in the latest report) . Alternatively, at least one inference related parameters associated with the CSI report is included in a set of applicable inference related parameters reported by UE (in the latest report) .
[0216] Optionally, in some embodiments, UE may determine what information (e.g., whether predicted CSI or measured CSI) needed to be calculated (or determined) based on: an indication of whether predicted CSI or measured CSI needs to be determined (or / and reported) associated with the CSI report.
[0217] In some embodiments, for a (triggered) monitoring CSI report, before a (triggered) inference CSI report is associated with the monitoring CSI report is stopped, UE may perform at least one first measurement behavior for the monitoring CSI report. If (or after) the (triggered) inference CSI report is associated with the monitoring CSI report is stopped, UE may perform at least one second measurement behavior for the monitoring CSI report, or a third behavior.
[0218] In some embodiments, the at least one first measurement behavior comprises at least one of the following: performing measurement (e.g., determine measured CSI) based on measurement resources associated with the monitoring CSI report, and / or performing measurement (e.g., determine performance metric) based on the measured CSI and predicted CSI determined based on the inference CSI report associated with the monitoring CSI report.
[0219] In some embodiments, the at least one second measurement behaviour may comprise at least one of the following: performing measurement (e.g., determine measured CSI) based on measurement resources associated with the monitoring CSI report, performing measurement and inference (e.g., determine predicted CSI) based on measurement resources and prediction resources (or resources not configured for measurement) associated with the inference CSI report associated with the monitoring CSI report, and / or performing measurement (e.g., calculate performance metric) based on the measured CSI and the predicted CSI.
[0220] In some embodiments, for the at least one second measurement behavior, if Set B is different from Set A, e.g., measurement resources (i.e., Set B) associated with the inference CSI report associated with the monitoring CSI report does not overlap with (or different from, is not subset of, not belong to, is not included in) prediction resources (i.e., Set A) associated with the inference CSI report associated with the monitoring CSI report, the at least one second measurement behaviour may comprise at least one of the above. Optionally, UE may stop (or skip) the monitoring CSI report.
[0221] Furthermore, if Set B is a subset of Set A, e.g., measurement resources (i.e., Set B) associated with the inference CSI report associated with the monitoring CSI report is a subset of (or is included in, overlaps partially with) prediction resources (i.e., Set A) associated with the inference CSI report associated with the monitoring CSI report, the at least one second measurement behaviour may comprise performing measurement (s) (e.g., determine measured CSI) and inference (e.g., predicted CSI) based on measurement resources associated with the monitoring CSI report, where the resources (e.g., Set B and Set A) for inference may be determined based on (relation between) measurement resources and prediction resources associated with the inference CSI report associated with the monitoring CSI report, and the measurement resources associated with the monitoring CSI report. Alternatively, or in addition, in some embodiments, the at least one second measurement behaviour may comprise performing the measurement (e.g., calculate performance metric) based on the measured CSI and the predicted CSI.
[0222] Furthermore, if Set B is the same as Set A, e.g., measurement resources (i.e., Set B) associated with the inference CSI report associated with the monitoring CSI report is the same as (or overlaps fully with) prediction resources (i.e., Set A) associated with the inference CSI report associated with the monitoring CSI report, the at least one second measurement behaviour may comprise at least one of the following: performing measurement (e.g., determine measured CSI) and inference (e.g., predicted CSI) based on measurement resources associated with the monitoring CSI report, and / or performing measurement (e.g., calculate performance metric) based on the measured CSI and the predicted CSI.

[0224] Furthermore, if Set B is different from Set A, e.g., measurement resources (i.e., Set B) associated with the inference CSI report associated with the monitoring CSI report does not overlap with (or different from, is not subset of, not belong to, is not included in) prediction resources (i.e., Set A) associated with the inference CSI report associated with the monitoring CSI report, the at least one second measurement behaviour may comprise at least one of the above. Optionally, UE may stop (or skip) the monitoring CSI report.
[0225] In some embodiments, a monitoring CSI report may be associated with multiple (sub-) configurations, e.g., two configurations: a first configuration and a second configuration.
[0226] In some embodiments, the first configuration may comprise measurement resources (e.g., 1 CSI-Resource is configured) and an ID of inference CSI report.
[0227] In some embodiments, the second configuration may comprise measurement resources and prediction resources. In some embodiments, the second configuration may comprise 3 CSI-Resources, i.e., 3 CSI-ResourceConfigIds may be configured, e.g., CSI-Resource-0 is configured as measurement resources (e.g., for monitoring) , CSI-Resource-1 is configured as measurement resources (e.g., for inference) , CSI-Resource-2 is configured as prediction resources (e.g., for inference) .
[0228] Alternatively, in some embodiments, the second configuration may comprise 2 CSI-Resources, i.e., 2 CSI-ResourceConfigIds may be configured, e.g., CSI-Resource-0 is configured as measurement resources (e.g., for inference) , CSI-Resource-1 is configured as measurement resources and prediction resources (e.g., for inference and monitoring) .
[0229] Alternatively, in some embodiments, the second configuration may comprise 1 CSI-Resource, i.e., 1 CSI-ResourceConfigId may be configured, e.g., CSI-Resource-0 is configured as measurement resources and prediction resources (e.g., for inference and monitoring) .
[0230] In some embodiments, for a triggered monitoring CSI report, before an inference CSI report associated with the monitoring CSI report is triggered, or / and after the inference CSI report associated with the monitoring CSI report is stopped, UE may apply the second configuration; otherwise, UE may apply the first configuration. Furthermore, the UE measurement (and inference, reporting) behavior corresponding to the first or second configuration may be the first / second / third behavior as discussed above.
[0231] Optionally, NW may send a command (e.g., RRC / MAC CE / DCI, the first or second command in Case 1) to UE to indicate which configuration is applied, e.g., ID of configuration may be indicated.
[0232] In some embodiments, for a monitoring CSI report, if the monitoring CSI report is not associated with an ID of inference CSI report, UE may assume that the measurement resources (e.g., CSI-Resource) associated with the monitoring CSI report is used as measurement resources (e.g., for inference and monitoring) and prediction resources (e.g., for inference) . For example, in case of ‘Set B is the same as Set A’ , the (same) CSI-Resource associated with the monitoring CSI report is used for determining measured results of Set A (as ground-truth label) , and inference results of Set A (determined based on measured results of Set B and prediction resources corresponding to Set A) .
