[0002] In New Radio (NR), especially at higher operating frequencies, beam-based transmission and reception are required to ensure coverage. During beam management, network devices configure a set of reference signal resources for beam measurement. The terminal measures the reference signal resources in this set and reports the measurement results to the network device.

[0003] With the development of communication technology, terminals can perform beam prediction using artificial intelligence (AI) technology. Summary of the Invention

[0073] As shown in Figure 1, the communication system 100 includes a terminal 101 and a network device 102.

[0079] In some embodiments, the access network device may be composed of a central unit (CU) and a distributed unit (DU). The CU may also be called a control unit. The CU-DU structure can separate the protocol layer of the access network device. Some of the protocol layer functions are centrally controlled by the CU, while the remaining part or all of the protocol layer functions are distributed in the DU and centrally controlled by the CU. However, this is not the only possibility.

[0083] The embodiments disclosed herein can be applied to Long Term Evolution (LTE), LTE-Advanced (LTE-A), LTE-Beyond (LTE-B), SUPER 3G, IMT-Advanced, 4th generation mobile communication system (4G), 5th generation mobile communication system (5G), 5G new radio (NR), 6th generation mobile communication system (6G), Future Radio Access (FRA), New-Radio Access Technology (RAT), New Radio (NR), New radio access (NX), Future generation radio access (FX), Global System for Mobile communications (GSM), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi), IEEE 802.16 (WiMAX), and IEEE 802.20, Ultra-Wideband (UWB), Bluetooth (a registered trademark), Public Land Mobile Network (PLMN) networks, Device-to-Device (D2D) systems, Machine-to-Machine (M2M) systems, Internet of Things (IoT) systems, Vehicle-to-Everything (V2X) systems, systems utilizing other communication methods, and next-generation systems built upon them, etc. Furthermore, multiple systems can be combined (e.g., a combination of LTE or LTE-A with 5G).

[0084] In NR, especially when the communication frequency band is in the Frequency Range (FR) 2, high-frequency channels attenuate quickly, so beam-based transmission and reception are required to ensure coverage.

[0085] During beam management, the network device configures a set of reference signal resources for beam measurement. The terminal measures the reference signal resources in this set. The terminal reports the identifiers (IDs) of the X strongest reference signal resources, along with their corresponding Layer 1 Reference Signal Receiving Power (L1-RSRP) and / or Layer 1 Signal to Interference plus Noise Ratio (L1-SINR), to the network device, where X is a positive integer.

[0086] In related technologies, it is assumed that the network device's set of reference signal resources includes X reference signal resources, each corresponding to a different transmit beam of the network device. For each reference signal resource, the terminal needs to use all receive beams to measure the reference signal, obtain the beam measurement quality corresponding to each receive beam, and determine one or more of the best beam measurement qualities. Therefore, the number of beam pairs that the terminal needs to measure is M*N. Here, M represents the number of transmit beams of the network device, N is the number of receive beams of the terminal, and * represents multiplication.

[0087] In some embodiments, an implementation process for beam prediction based on artificial intelligence (AI) models and / or AI functions is provided. Here, AI functions can be considered as one or more AI models that achieve a certain function or purpose.

[0088] In some embodiments, the AI ​​model used for beam prediction may be referred to as a beam prediction model. Of course, it may also be called a beam prediction AI model, a prediction AI model, a prediction beam model, etc. This disclosure does not limit the name of such AI model.

[0089] In some embodiments, when the AI ​​model is a spatial prediction, the L1-RSRP of the terminal measurement set (set) B (which may also include beam or beam pair ID) is input into the AI ​​model to predict the L1-RSRP of the best beam and / or beam pair in set A, and / or the identifier of the best beam and / or beam pair in set A.

[0090] The relationship between set B and set A includes the following two types:

[0091] The first type of relationship is that set B is a subset of set A. For example, if set A contains 32 reference signal resources (each reference signal resource corresponds to a beam direction), then set B contains N partial reference signal resources. For instance, set B contains 8 of the 32 reference signal resources, i.e., N = 8.

[0092] The second relationship is as follows: set B is a wide beam, and set A is a narrow beam. For example, set A contains 32 reference signal resources (each reference signal resource corresponds to one beam direction, and the 32 reference signal resources cover a 120-degree direction). Set B contains another Y reference signal resources, for example, Y=8. These Y reference signal resources also cover a 120-degree direction, meaning that the beam direction of each reference signal resource in set B covers the beam directions of multiple reference signal resources in set A. This can be understood as a quasi-co-location (QCL) type (Type) D relationship between the 32 / Y reference signal resources in set A and one reference signal resource in set B.

[0093] Understandably, the examples of the first and second relationships described above only depict the case of the transmitted beam. When considering beam pairs that include both transmitted and received beams, the terminal's received beam must also be considered. For example, with 32 transmitted beams and 4 received beams, set A would be 32*4 beam pairs, and set B could be 32 beam pairs, 16 beam pairs, and so on.

[0094] If monitoring the performance of the AI ​​model is not required, assuming that the AI ​​model has been pre-trained, the network device only needs to periodically send the reference signal of set B (e.g., in the first cycle). Then, the terminal measures the L1-RSRP of the reference signal in set B and inputs it into the AI ​​model. The model can then output the L1-RSRP of all beams or beam pairs in set A, or output the IDs of the K strongest reference signals or beam pairs among the 32 reference signals in set A.

[0095] If monitoring AI model performance is required, in addition to sending set B, the network device is also required to periodically send reference signals for set A (e.g., the second period, which is longer than the first period; whether it's a multiple of the first period or by how much longer is not restricted here). The terminal then only measures the result of set B and inputs it into the AI ​​model to obtain the predicted beam information, which is then reported to the network device. Simultaneously, the L1-RSRP of all reference signals in set A is measured, and the beam information is obtained and reported to the network device. Of course, if set B is a subset of set A, it's equivalent to the terminal only needing to measure all beams or beam pairs in set A.

[0096] In some embodiments, when the AI ​​model is a time-domain prediction, the terminal measures the L1-RSRP of historical time set B, inputs it into the AI ​​model, and predicts the L1-RSRP of future time set A. Besides the two relationships mentioned above, there is another relationship between set B and set A: set B and set A are the same.

[0097] If beam prediction is based on an AI model, then the reference signal for future moments does not need to be sent; that is, beam information can be obtained based on the output of the AI ​​model and reported to the network equipment.

[0098] If beam prediction is performed using methods from related technologies, reference signals for future timeframes also need to be transmitted for performance monitoring. The terminal measures the reference signals for future timeframes and obtains beam information, which is then reported to the base station. Therefore, during model performance monitoring, for co-spatial beam prediction, network devices need to periodically transmit the transmitted beams in set B and set A, and the terminal needs to measure all beams or beam pairs in set B and set A.

[0099] In related technologies, AI-based prediction methods have been proposed to reduce the number of beams or beam pairs measured by the terminal. However, these methods only consider beam prediction within the same serving cell. For example, if a serving cell contains a total of 32 transmit beams, in spatial beam prediction, the terminal only measures 8 of these transmit beams to predict the prediction results of all transmit beams. In temporal beam prediction, the terminal measures at least a portion of the 32 transmit beams from historical times to predict the prediction results of all transmit beams in the future.

[0100] However, a terminal may be configured with multiple serving cells, requiring beam measurement for each. This incurs significant reference signal resource overhead and increases the terminal's measurement complexity. Similarly, the same issue arises when the terminal needs to measure the beams of neighboring cells. Therefore, reporting the terminal's ability to predict beams across different cells is a problem that needs to be addressed.

[0101] This disclosure provides a communication method in which a terminal sends first information to a network device. The first information indicates that the terminal has a first capability, which is the ability to obtain a second value of a second reference signal resource corresponding to a second cell based on a first value of a first reference signal resource corresponding to a first cell. The terminal's ability to obtain the second value of a second reference signal resource corresponding to a second cell based on the first value of the first reference signal resource corresponding to the first cell can save communication resources used by the terminal for measurement. The terminal reports the first information to the network device, enabling the network device to be configured based on the capabilities supported by the terminal, thereby improving communication efficiency.

[0102] Figure 2A is an interactive schematic diagram of a communication method according to an embodiment of the present disclosure. As shown in Figure 2A, the embodiments of the present disclosure relate to a communication method, which includes:

[0103] Step S2101: The terminal sends the first information to the network device.

[0104] In some embodiments, the network device receives first information sent by the terminal.

[0105] In some embodiments, the first information indicates that the terminal has a first capability, which is the ability to obtain a second value of a second reference signal resource based on a first value of a first reference signal resource. The first reference signal resource is the reference signal resource corresponding to a first cell, and the second reference signal resource is the reference signal resource corresponding to a second cell. The first cell and the second cell are different.

[0106] In some embodiments, the terminal has predictive capabilities based on AI functions or AI models or machine learning (ML) functions or ML models.

[0107] In this embodiment of the disclosure, AI can be replaced with AI model, AI function, ML function, or ML model. This embodiment of the disclosure uses AI model as an example for illustration, but is not limited thereto.

[0108] In some embodiments, the terminal can obtain a second value of a reference signal resource corresponding to a second cell based on a first value of a reference signal resource corresponding to a first cell. For ease of description, the reference signal resource corresponding to the first cell is referred to as the first reference signal resource, and the reference signal resource corresponding to the second cell is referred to as the second reference signal resource. There may be one or more first reference signal resources, and there may also be one or more second reference signal resources.

[0109] In some embodiments, the reference signal resources (including but not limited to the first reference signal resources and the second reference signal resources) may be a synchronization signal block (SSB) or a channel state information reference signal (CSI-RS).

[0110] In some embodiments, the first value may be a measured value obtained from actual measurement, and the second value may be a predicted value obtained based on AI prediction.

[0111] In some embodiments, the terminal measures the first reference signal resource to obtain a first value of the first reference signal resource; and processes the first value of the first reference signal resource based on artificial intelligence (AI) or machine learning (ML) to obtain a second value of the second reference signal resource.

[0112] For example, the terminal can measure at least one first reference signal resource corresponding to the first cell to obtain the measurement value of each first reference signal resource. The terminal can then use the measured values ​​of the first reference signal resources and AI prediction to obtain the predicted value of the second reference signal resource corresponding to the second cell. Alternatively, the terminal can use the measured values ​​of the first reference signal resources and ML prediction to obtain the predicted value of the second reference signal resource corresponding to the second cell. For instance, the terminal can input the measured values ​​of the first reference signal resources into a trained AI or ML model and output the predicted value of the second reference signal resource corresponding to the second cell.

[0113] In some embodiments, the first value includes at least one of the following values: Layer 1 Reference Signal Receiving Power (L1-RSRP); Layer 1 signal to interference plus noise ratio (L1-SINR); Layer 3 Reference Signal Receiving Power (L3-RSRP); Layer 3 Reference Signal Receiving Quality (L3-RSRQ); Layer 3 Received Signal Strength Indication (L3-RSSI); and Channel State Information (CSI).

[0114] CSI can include, but is not limited to, Pre-coding matrix Indication (PMI), Rank Indicator (RI), and Continuous Quality Improvement (CQI).

[0115] In some embodiments, the terminal may measure at least one of the above-mentioned first reference signal resources to obtain a measurement value, which is used to obtain a second value of the second reference signal resource.

[0116] For example, the terminal can measure the L1-RSRP of the first reference signal resource to obtain the L1-RSRP value of the first reference signal resource, and use the L1-RSRP value to obtain the second value of the second reference signal resource.

[0117] In some embodiments, the second value includes at least one of the following values: L1-RSRP; L1-SINR; L3-RSRP; L3-RSRQ; L3-RSSI; CSI; and the identifiers of the K reference signal resources with the best quality information in the second reference signal resource, wherein the quality information is one of L1-RSRP, L1-SINR, L3-RSRP, L3-RSRQ, L3-RSSI, and CSI, and K is a positive integer.

[0118] In some embodiments, the terminal can obtain the value corresponding to at least one of the above-mentioned items of the second reference signal resource based on the first value of the first reference signal resource. The terminal can predict the value of at least one of L1-RSRP, L1-SINR, L3-RSRP, L3-RSRQ, L3-RSSI, and CSI of the second reference signal resource, and can also predict the identifiers of the K best second reference signal resources, wherein the K best second reference signal resources refer to the K second reference signal resources ranked first from the strongest to the weakest of the values ​​of at least one of L1-RSRP, L1-SINR, L3-RSRP, L3-RSRQ, L3-RSSI, and CSI.

[0119] Wherein, K is an integer greater than or equal to 1, and the value of K can be set according to the actual situation. For example, it can be an instruction from the network device to the terminal, or it can be a predefined protocol. This disclosure does not limit the value of K.

[0120] For example, the terminal can predict the L1-RSRP value of the second reference signal resource, and it can also predict the identifiers of the K second reference signal resources with the largest L1-RSRP values.

[0121] In this embodiment of the disclosure, the first cell and the second cell are different cells, that is, the terminal can obtain the second value of the reference signal resource of the other cell based on the first value of the reference signal resource of the first cell.

[0122] The first and second communities are described below.

[0123] In some embodiments, the first cell is the serving cell of the terminal, and the second cell is a cell other than the serving cell.

[0124] In some embodiments, the second cell is not the serving cell of the terminal; for example, the second cell may be a neighboring cell of the terminal.

[0125] In some embodiments, the first cell and the second cell correspond to the same frequency band.

[0126] In some embodiments, the first cell and the second cell correspond to the same frequency band.

[0127] For example, the Absolute Radio Frequency Channel Number (ARFCN) values ​​of the first cell and the second cell are the same, and the frequency band corresponding to the ARFCN value is specified by the protocol.

[0128] In some embodiments, the second cell is one of several types of second cells, and the distance between each type of second cell and the first cell is different.

[0139] In some embodiments, the terminal is configured with multiple serving cells, where the first cell and the second cell are both serving cells of the terminal. For example, the first cell is one serving cell of the terminal, and the second cell is another serving cell of the terminal.

[0140] In some embodiments, the first cell and the second cell correspond to different frequency bands.

[0147] In some embodiments, the band number and the band range corresponding to each band number are shown in Tables 2 and 3.

[0148] Table 2

[0149] The relevant notes in Table 2 can be found in the agreement.

[0150] Table 3

[0151] In some embodiments, the first indication information may indicate a frequency band number or a combination of frequency bands, which includes multiple frequency band numbers. Similarly, the second indication information may indicate a frequency band number or a combination of frequency bands, which includes multiple frequency band numbers.

[0152] For example, the frequency band combination indicated by the first indication information is {n1, n2, n3}, and the frequency band combination indicated by the second indication information is {n257, n258}.

[0153] In some embodiments, each band combination may correspond to a band combination number, and the first indication information may indicate the band combination number. Based on the band combination number, the band combination and the band numbers included in the band combination can be determined. Similarly, the second indication information may also indicate the band combination number. The band combination number indicated by the first indication information and the band combination number indicated by the second indication information are different.

[0154] In some embodiments, the first indication information can indicate the ARFCN, and the second indication information can also indicate the ARFCN. The value range of NR-ARFCN is [0, 1, ..., 3279165]. Based on the ARFCN value and the following formula, the frequency band corresponding to the ARFCN value can be obtained from [a certain number of MHz] to [a certain number of MHz]. REF =F REF-Offs +ΔF Global (N REF –N REF-Offs )

[0155] The ranges of each parameter in the formula are shown in Table 4.

[0156] Table 4 NR-ARFCN parameters for global frequency grid

[0157] Among them, F REF This refers to the reference frequency, N. REF This refers to NR-ARFCN, ΔF Global This refers to the frequency domain granularity, F REF-Offs This refers to frequency offset, N REF-Offs This refers to the number offset.

[0158] In some embodiments, the first indication information may indicate a single ARFCN or a combination of ARFCNs, wherein the combination of ARFCNs includes multiple ARFCNs. Similarly, the second indication information may indicate a single ARFCN or a combination of ARFCNs, wherein the combination of ARFCNs includes multiple ARFCNs.

[0159] In some embodiments, each ARFCN combination may correspond to an ARFCN combination number. The first indication information may indicate the ARFCN combination number, and based on the ARFCN combination number, the ARFCN combination and the ARFCNs included in the ARFCN combination can be determined. Similarly, the second indication information may also indicate the ARFCN combination number. The ARFCN combination number indicated by the first indication information and the ARFCN combination number indicated by the second indication information are different.

[0160] In some embodiments, the first instruction information can be any one of the five types of information mentioned above, and the second instruction information can also be any one of the five types of information mentioned above. The types of information corresponding to the first instruction information and the second instruction information can be the same or different. Theoretically, there can be 25 combinations of the first instruction information and the second instruction information.

[0161] For example, the first indication information indicates FR1, and the second indication information indicates FR2-1, FR2-2, or FR3. That is, the terminal predicts the value of the second cell FR2-1, FR2-2, or FR3 based on the measurement value of the first cell FR1.

[0162] For example, if the first indication information indicates {n1, n2, n3} and the second indication information indicates {n257, n258}, then it means that the terminal can support the first cell when it is in any one of the frequency bands in the frequency band combination {n1, n2, n3} and the second cell when it is in any one of the frequency bands in the frequency band combination {n257, n258}.

[0163] For example, if the first indication information indicates {ARFCN1, ARFCN2, ARFCN3} and the second indication information indicates {ARFCN257, ARFCN258}, then it means that the terminal can support the first cell when it is in any one of the frequency bands in the combination {ARFCN1, ARFCN2, ARFCN3} and the second cell when it is in any one of the frequency bands in the combination {ARFCN257, ARFCN258}.

[0164] For example, if the first indication information indicates {n1, n2, n3} and the second indication information indicates {ARFCN257, ARFCN258}, then it means that the terminal can support the first cell when it is in any frequency band of the combination {n1, n2, n3} and the second cell when it is in any frequency band of the combination {ARFCN257, ARFCN258}.

[0165] In some embodiments, the second cell is one of several types of second cells, and the distance between each type of second cell and the first cell is different.

[0166] In some embodiments, the multiple types may include a first type of second cell, a second type of second cell, and a third type of second cell, wherein the distance between each type of cell and the first cell is different.

[0167] In some embodiments, the first type of second cell is closest to the first cell, the second type of second cell is closer to the first cell than the first type of second cell, and the third type of second cell is closer to the first cell than or equal to the second type of second cell.

[0168] In some embodiments, the second cell of the first type shares a site with the first cell.

[0169] In some embodiments, the second type of second cell and the third type of second cell are not co-located with the first cell.

[0170] In some embodiments, the second type of second cell is located within the first cell; the third type of second cell is adjacent to the first cell, that is, there are no other cells between the third type of second cell and the first cell.

[0171] For example, referring to Figure 2B, the first community can be community 221, the first type of second community shares the same site with the first community, and the second type of second community is located within the first community; the third type of second community is adjacent to the first community, and the third type of second community can be one of the communities 222, and community 222 is adjacent to community 221.

[0174] In some embodiments, the locational relationship between the first cell and the second cell may include one of the following: the first cell and the second cell are co-located; the first cell and the second cell are not co-located and are adjacent; the first cell and the second cell are not co-located and the first cell is located within the second cell; or the first cell and the second cell are not co-located and the second cell is located within the first cell.

[0175] The communication method provided in this embodiment includes a terminal sending first information to a network device. The first information indicates that the terminal has a first capability, which is the ability to obtain a second value of a second reference signal resource corresponding to a second cell based on a first value of a first reference signal resource corresponding to a first cell.

[0215] In some embodiments, the above methods may include the methods of the embodiments described above on the communication system side, terminal side, network device side, etc., which will not be repeated here.

[0216] This disclosure proposes a method for reporting beam prediction capabilities between different cells, including beam prediction results of neighboring cells based on beam measurement results of a serving cell.

[0217] In some embodiments, the terminal reports a supported first function, which is to predict the measurement value of the reference signal resource corresponding to the second cell based on the measurement value of the reference signal resource corresponding to the first cell.

[0218] In some embodiments, the first cell is the serving cell of the terminal, and the second cell is not the serving cell of the terminal.

[0219] In some embodiments, the first cell and the second cell correspond to the same frequency band.

[0220] For example, two cells may have the same ARFCN value (the protocol specifies that the frequency band corresponding to the ARFCN value is from a certain MHz to a certain MHz).

[0221] In some embodiments, the first cell and the second cell share a site, or the first cell and the second cell do not share a site.

[0222] In some embodiments, when the first cell and the second cell are not co-located, the positional relationship between the first cell and the second cell includes at least one of the following:

[0223] The first and second communities are adjacent communities, meaning there are no other communities between them; for example, according to Figure 2B, the first community is community 221, and the second community is one of community 222.

[0224] There are other communities between the first community and the second community. For example, the first community is community 221 in Figure 2B, and the second community is one of the communities 223.

[0225] The first residential area is located within the second residential area, or the second residential area is located within the first residential area.

[0226] The above three scenarios can be described as Category 1 Second Community, Category 2 Second Community, and Category 3 Second Community. Category 1 Second Community is the closest to Category 1 Community, Category 2 is next, and Category 3 is the furthest. Even co-located communities can be described as a single category, meaning that the community closest to Category 1 Community compared to non-co-located communities is the closest.

[0227] In some embodiments, both the first cell and the second cell are serving cells for the terminal.

[0228] In some embodiments, the first cell and the second cell correspond to different frequency bands.

[0229] For example, the ARFCN values ​​of the two cells are different (the protocol specifies that the frequency band corresponding to the ARFCN value is from a certain number of MHz to a certain number of MHz).

[0230] In some embodiments, the first cell corresponds to a first frequency band, and the second cell corresponds to a second frequency band. The first frequency band or the second frequency band includes at least one of the following:

[0231] FR number:

[0232] FR1: Frequency range 1 (corresponding to the range in Table 1);

[0233] FR2-1: Frequency range 2-1 (corresponding to the range in Table 1);

[0234] FR2-2: Frequency range 2-2 (corresponding to the range in Table 1);

[0235] FR3: Frequency range 3 (corresponding to the frequency band between FR1 and FR2-1 in Table 1, i.e., 7125MHz~24250MHz);

[0236] Band numbers are shown in Tables 2 and 3. The frequency range corresponding to each band number is included in the tables in the protocol.

[0237] A combination of band numbers, or a combination of band numbers;

[0238] That is, a combination includes multiple band numbers, for example, the first band contains {n1, n2, n3}, and the second band contains {n257, n258};

[0239] ARFCN value;

[0240] The NR-ARFCN value ranges from [0, 1, ..., 3279165]. Based on the ARFCN value and the formula, the frequency band corresponding to the ARFCN value can be obtained from how many MHz to how many MHz.

[0241] A combination of ARFCN values, or a combination of ARFCN values; that is, a combination contains multiple ARFCN values.

[0242] Since both frequency bands can correspond to any one of the five, theoretically, there are 25 possible combinations between the first and second frequency bands.

[0243] Typically, the first function indicates the measurement value of the first cell based on FR1, and predicts the value of the second cell based on FR2-1, FR2-2, or FR3.

[0244] For example, the first function indicates the measurement value of the first cell based on the first frequency band and the predicted value of the second cell based on the second frequency band. The first frequency band includes {n1, n2, n3} and the second frequency band includes {n257, n258}. This means that the terminal can support the first cell being in any frequency band of the first frequency band combination and the second cell being in any frequency band of the second frequency band combination.

[0245] For example, the first function indicates the measurement value of the first cell based on the first frequency band and the predicted value of the second cell based on the second frequency band. The first frequency band includes {ARFCN1, ARFCN2, ARFCN3} and the second frequency band includes {ARFCN257, ARFCN258}. This means that the terminal can support the first cell being in any frequency band of the first frequency band combination and the second cell being in any frequency band of the second frequency band combination.

[0246] In some embodiments, the first cell and the second cell share a site, or the first cell and the second cell do not share a site.

[0247] In some embodiments, when the first cell and the second cell are not co-located, the positional relationship between the first cell and the second cell includes at least one of the following:

[0248] The first and second residential areas are adjacent to each other, meaning there are no other residential areas between them.

[0249] The first residential area is located within the second residential area, or the second residential area is located within the first residential area.

[0250] The above two scenarios can be described as Category 1 Second Cell and Category 2 Second Cell, respectively. Category 1 Second Cell is closest to Category 1 Cell, and Category 2 is next in distance. Even co-located cells can be described as a single category, meaning that the cell closest to Category 1 Cell compared to non-co-located cells is the closest.

[0251] The measured values ​​include at least one of the following: L1-RSRP, L1-SINR, L3-RSRP, L3-RSRQ, L3-RSSI, CSI (PMI, RI, CQI, etc.).

[0252] The predicted value includes at least one of the following:

[0253] At least one of the following: L1-RSRP, L1-SINR, L3-RSRP, L3-RSRQ, L3-RSSI, CSI (PMI, RI, CQI, etc.);

[0254] The identifier of the reference signal resources corresponding to the Top K in the second cell. For example, the Top K are the identifiers of the reference signal resources that are ranked from strong to weak according to at least one of the above criteria.

[0255] This disclosure proposes a terminal capability reporting method that enables the reporting terminal to support AI-based predictions between different cells, where different cells can operate on the same or different frequencies, further reducing reference signal overhead and terminal measurement complexity.
