[0078] As shown in FIG. 1, the communication system 100 includes a terminal 101 and a network device 102.

At this time, the interfaces between or within the access network devices involved in the embodiments of the present disclosure may become the internal interfaces of the Open RAN, and the processes and information interactions between these internal interfaces can be implemented through software or programs.

[0084] In some embodiments, the access network device may be composed of a central unit (CU) and a distributed unit (DU). Among them, the CU may also be referred to as a control unit. The use of the CU-DU structure can split the protocol layer of the access network device. The functions of some protocol layers are centrally controlled by the CU, and the functions of the remaining part or all protocol layers are distributed in the DU. The DU is centrally controlled by the CU, but is not limited thereto.

[0085] In some embodiments, the core network device may be a single device including one or more network elements, or may be multiple devices or a group of devices, each including all or part of the above-mentioned one or more network elements.

Those of ordinary skill in the art will know that with the evolution of the system architecture and the emergence of new service scenarios, the technical solutions proposed in the embodiments of the present disclosure are equally applicable to similar technical problems.

[0087] The following embodiments of the present disclosure can be applied to the communication system 100 shown in FIG. 1, or part of the entities, but are not limited thereto. Each entity shown in FIG. 1 is an illustration. The communication system may include all or part of the entities in FIG. 1, or may include other entities outside FIG. 1. The number and form of each entity are arbitrary. Each entity may be physical or virtual. The connection relationships between the entities are illustrations.

[0088] Embodiments of the present disclosure 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 (registered trademark)), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi (registered trademark)), IEEE 802.16 (WiMAX (registered trademark)), IEEE 802.20, Ultra-WideBand (UWB), Bluetooth (registered trademark), Public Land Mobile Network (PLMN) network, Device-to-Device (D2D) system, Machine to Machine (M2M) system, Internet of Things (IoT) system, Vehicle-to-Everything (V2X), systems using other communication methods, next-generation systems extended based on them, etc. In addition, multiple systems can be combined (for example, a combination of LTE or LTE-A and 5G, etc.) and applied.

[0089] In NR, especially when the communication frequency band is in Frequency Range (FR) 2, due to the relatively fast attenuation of high-frequency channels, in order to ensure the coverage range, beam-based transmission and reception need to be used.

[0090] In the beam management process, the network device configures a set of reference signal resources for beam measurement. The terminal measures the reference signal resources in the set of reference signal resources. The terminal reports X relatively strong reference signal resource identifiers (IDs) and the 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.

[0091] In the related art, it is assumed that the set of reference signal resources configured by the network device includes X reference signal resources, and each reference signal resource corresponds to a different transmission beam of the network device. For each reference signal resource, the terminal needs to use all receiving beams to measure the reference signal, obtain the beam measurement quality corresponding to each receiving beam, and determine one or more best beam measurement qualities. Therefore, the number of beam pairs that the terminal needs to measure is M * N. Where M represents the number of transmission beams of the network device, N is the number of receiving beams of the terminal, and * represents the multiplication operation.

[0092] In some embodiments, an implementation process of beam prediction based on an Artificial Intelligence (AI) model and / or AI function is provided. The AI function can be considered as one or more AI models that implement the same function and use.

[0093] In some embodiments, the AI model for beam prediction can be called a beam prediction model. Of course, it can also be called a beam prediction AI model, a prediction AI model, a prediction beam model, etc. The present disclosure does not limit the names of such AI models.

[0094] In some embodiments, in the case where the AI model is for airspace prediction, the terminal measures the L1-RSRP of set B (which can also include beam or beam pair IDs), inputs it into the AI model, and predicts 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.

[0095] The relationship between set B and set A includes the following two types:

[0096] The first 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 example, set B contains 8 reference signal resources out of the 32 reference signal resources, that is, N = 8.

[0097] The second relationship is that 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 a beam direction, and the 32 reference signal resources cover a 120-degree direction). And set B contains another Y reference signal resources, for example, Y = 8. And these Y reference signal resources also cover a 120-degree direction, that is, the beam direction of each reference signal resource in set B covers the beam directions of multiple reference signal resources in set A. It can be understood that the relationship between 32 / Y reference signal resources in set A and one reference signal resource in set B is of the quasi co location (QCL) type D.

[0098] It can be understood that in the examples of the above first relationship and second relationship, only the case of the transmit beam is described. When considering beam pairs including transmit beams and receive beams, the receive beam of the terminal also needs to be considered. For example, for 32 transmit beams and 4 receive beams, then set A is 32 * 4 beam pairs, and set B can be 32 beam pairs, 16 beam pairs, etc.

[0099] If it is not necessary to monitor the performance of the AI model, assuming that the AI model has been trained in advance, then the network device only needs to periodically send the reference signals of set B (such as the first period), and then the terminal measures the L1-RSRP of the reference signals in set B and inputs it into the AI model, and then the L1-RSRP of all beams or beam pairs in set A can be output, or the IDs of the K strongest reference signals or beam pairs among the 32 reference signals in set A can be output.

[0100] If it is necessary to monitor the performance of the AI model, in addition to sending set B, it is also required that the network device periodically sends the reference signals of set A (such as the second period, and the second period is greater than the first period. Regarding whether it is a multiple of the first period and how much larger it is than the first period, there is no limit here). Then the terminal only measures the results of set B and inputs them into the AI model to obtain the predicted beam information and report it to the network device. At the same time, it also measures the L1-RSRP of all reference signals in set A and obtains the beam information and reports it to the network device. Of course, if set B is a subset of set A, it is equivalent to the terminal only needing to measure all beams or beam pairs in set A.

[0101] 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.

[0102] 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.

[0103] 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.

[0104] 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.

[0105] However, a terminal may be configured with multiple serving cells, requiring beam measurement for each cell. This incurs significant reference signal resource overhead and increases the measurement complexity for the terminal. Similarly, the same issue arises when the terminal needs to measure the beams of neighboring cells.

[0106] This disclosure provides a communication method in which a network device sends first information to a terminal. The first information includes information about a first reference signal resource set, a first cell identifier, and a second cell identifier. The first cell identifier corresponds to the first reference signal resource set, and the second cell identifier corresponds to the second reference signal resource set. The terminal determines information about the second reference signal resource set based on the first information, and obtains a second value in the second reference signal resource set based on a first value of a first reference signal resource in the first reference signal resource set. This method can save communication resources used by the terminal for measurement, thereby improving communication efficiency.

[0107] Figure 2 is an interactive schematic diagram of a communication method according to an embodiment of the present disclosure. As shown in Figure 2, the embodiments of the present disclosure relate to a communication method, which includes:

[0108] Step S2101: The network device sends the first information to the terminal.

[0109] In some embodiments, the terminal receives first information sent by the network device.

[0110] In some embodiments, the first information may also be referred to as the first configuration information.

[0111] In some embodiments, the first information includes at least one of information on a first reference signal resource set, a first cell identifier, and a second cell identifier; wherein the first cell identifier corresponds to the first reference signal resource set, and the second cell identifier corresponds to the second reference signal resource set.

[0112] In some embodiments, the first set of reference signal resources includes one or more reference signal resources, and the second set of reference signal resources includes one or more reference signal resources. For ease of description, the reference signal resources in the first set of reference signal resources are referred to as first reference signal resources, and the reference signal resources in the second set of reference signal resources are referred to as second reference signal resources.

[0113] In some embodiments, the first reference signal resource is used for measurement, and the terminal can measure the first reference signal resource to obtain a first value of the first reference signal resource.

[0114] In some embodiments, the terminal has predictive capabilities based on AI functions or AI models or machine learning (ML) functions or ML models. The terminal can obtain a second value of a second reference signal resource based on a first value of a first reference signal resource.

[0115] 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.

[0116] 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).

[0117] 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 or ML prediction. For example, the terminal may measure a first reference signal resource to obtain a measured value of the first reference signal resource, and the terminal may obtain a predicted value of a second reference signal resource based on the measured value of the first reference signal resource and AI prediction.

[0118] 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).

[0119] CSI can include, but is not limited to, Pre-coding matrix Indication (PMI), Rank Indicator (RI), and Continuous Quality Improvement (CQI).

[0120] 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.

[0121] 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.

[0122] 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.

[0123] 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.

[0124] The value of K can be set according to the actual situation. For example, it can be indicated by the network device to the terminal, or it can be predefined by the protocol. This disclosure does not limit the value of K.

[0125] 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.

[0126] In some embodiments, the information of the first reference signal resource set may include, but is not limited to, the time-domain resources, frequency-domain resources, number of ports, power information, QCL assumptions, etc., corresponding to each first reference signal resource.

[0127] In some embodiments, the first reference signal resource set corresponds to the first cell identifier, and the first cell identifier corresponds to the first cell; the second reference signal resource set corresponds to the second cell identifier, and the second cell identifier corresponds to the second cell, wherein the second cell may be one or more cells.

[0128] The first and second communities are described below.

[0129] In some embodiments, the first cell corresponding to the first cell identifier and the second cell corresponding to the second cell identifier are different serving cells.

[0130] 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.

[0131] In some embodiments, the Absolute Radio Frequency Channel Number (ARFCN) and Physical Cell Identifier (PCI) of each serving cell are configured to the terminal. This means the terminal knows the ARFCN and PCI of each serving cell. The ARFCN value determines the frequency band corresponding to the cell, ranging from MHz to MHz. Therefore, knowing the ARFCN value of a serving cell allows the terminal to determine its corresponding frequency band. Thus, after the network device indicates the first cell identifier and the second cell identifier to the terminal, the terminal can determine the first cell and its corresponding frequency band based on the first cell identifier, and the terminal can determine the second cell and its corresponding frequency band based on the second cell identifier.

[0132] For example, if a terminal is configured with four serving cells, and the serving cell index for each serving cell is 0, 1, 2, or 3, and the network device indicates that the second cell index is one of 0, 1, 2, or 3, the terminal can determine the second cell and its corresponding frequency band based on the second cell index.

[0133] In some embodiments, the first cell and the second cell belong to the same cell group, or the first cell and the second cell belong to different cell groups.

[0134] In some embodiments, the terminal is configured with multiple serving cells corresponding to two communication scenarios: one is carrier aggregation (CA), and the other is dual connection (DC).

[0135] In some embodiments, when the terminal is in a DC scenario, the site locations corresponding to the multiple serving cells configured for the terminal are different. The different serving cells can be divided into different cell groups, wherein the cell group can include a master cell group and a secondary cell group.

[0136] In some embodiments, the first cell and the second cell may belong to the same cell group, for example, the first cell and the second cell may both belong to the primary cell group, or the first cell and the second cell may both belong to the secondary cell group.

[0137] In some embodiments, the first cell and the second cell may belong to different cell groups. For example, the first cell may belong to the primary cell group and the second cell may belong to the secondary cell group; or, the second cell may belong to the primary cell group and the first cell may belong to the secondary cell group.

[0138] In some embodiments, the terminal is configured with one or more serving cell lists, and the serving cell lists of the first cell and the second cell are different; or, the Transmission Configuration Indicator (TCI) status list corresponding to the first cell is not applicable to the second cell.

[0139] In some embodiments, a terminal may be configured with one or more serving cell lists. The Transmission Configuration Indication (TCI) state ID corresponding to a serving cell in the same serving cell list can be applied to other serving cells in that list. For example, the TCI state ID on serving cell 1 activated by the Medium Access Control Element (MAC CE) can be applied to all serving cells in the serving cell list corresponding to serving cell 1. Therefore, if the serving cell lists of the first cell and the second cell are the same, the first value obtained by measuring the first reference signal resource corresponding to the first cell can be directly applied to the second reference signal resource corresponding to the second cell. Thus, it is not necessary to measure the second cell to obtain its second value, nor is it necessary to obtain the second value of the second cell based on the first value of the first cell. If the serving cell lists of the first cell and the second cell are different, the terminal needs to obtain either the first or second value of the second reference signal resource corresponding to the second cell after measuring the first reference signal resource corresponding to the first cell. Therefore, to reduce reference signal resource overhead and terminal measurement complexity, the second value of the second reference signal resource can be obtained based on AI or ML and the first value of the first reference signal resource.

[0140] In some embodiments, a TCI state list corresponding to one serving cell can be applied to another serving cell. For example, Radio Resource Control (RRC) can be used to configure a TCI state corresponding to one serving cell to be applicable to another serving cell. If the TCI state list corresponding to the first cell can be applied to the second serving cell, then after measuring the first reference signal resource corresponding to the first cell to obtain a first value, it can be directly applied to the second reference signal resource corresponding to the second cell. Therefore, it is not necessary to measure the second cell to obtain a second value, nor is it necessary to obtain a second value of the second cell based on the first value of the first cell. If the TCI state list corresponding to the first cell is not applicable to the second cell, then after the terminal measures the first reference signal resource corresponding to the first cell to obtain a first value, it is also necessary to obtain the first or second value of the second reference signal resource corresponding to the second cell. Therefore, in order to reduce the reference signal resource overhead and the measurement complexity of the terminal, the second value of the second reference signal resource can be obtained based on AI or ML and the first value of the first reference signal resource.

[0141] In some embodiments, the first cell corresponding to the first cell identifier is the serving cell of the terminal, and the second cell corresponding to the second cell identifier is a cell other than the serving cell of the terminal.

[0142] 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.

[0143] In some embodiments, the frequency bands corresponding to the first cell and the second cell may be the same, that is, the first cell and the second cell are on the same frequency.

[0144] In some embodiments, the frequency bands corresponding to the first cell and the second cell may be different, that is, the first cell and the second cell are on different frequencies.

[0145] In some embodiments, if the frequency bands corresponding to the first cell and the second cell are different, the network device also needs to indicate the frequency band information of the second cell to the terminal.

[0146] In some embodiments, the network device sends second information to the terminal.

[0147] In some embodiments, the terminal receives second information sent by the network device.

[0148] The second information includes the carrier frequency information of the second cell or the ARFCN corresponding to the second cell.

[0149] In some embodiments, the second information is included in the first information, or the second information is sent separately.

[0150] In some embodiments, the second information includes the carrier frequency information of the second cell, such as from a certain MHz to a certain MHz.

[0151] In some embodiments, the second information includes the ARFCN corresponding to the second cell, and the correspondence between the frequency bands corresponding to the ARFCN and the frequency bands is defined by the protocol. The terminal can determine the frequency band of the second cell based on the ARFCN corresponding to the second cell.

[0152] In some embodiments, the second cell identifier may be the PCI of a cell, or a number in a list corresponding to the second cell, the list containing one or more second cells on one or more frequencies, and at least one of the PCI and frequency of the second cell identifier can be determined based on the number.

[0153] In some embodiments, the first cell corresponding to the first cell identifier and the second cell corresponding to the second cell identifier are both cells other than the serving cell of the terminal; the first cell and the second cell are the same cell, or the first cell and the second cell are different cells.

[0154] In some embodiments, neither the first cell nor the second cell may be the serving cell of the terminal; for example, both may be neighboring cells of the terminal.

[0155] In some embodiments, the first cell and the second cell are the same cell, that is, the predicted value of the second reference signal resource set is obtained based on the measurement value of the first reference signal resource set of the same neighboring cell.

[0156] In some embodiments, the first cell and the second cell are different cells, that is, the predicted value of the second reference signal resource set of another neighboring cell is obtained based on the measurement value of the first reference signal resource set of one neighboring cell.

[0157] In some embodiments, the first information may further include information about the second set of reference signal resources; or, the first information may further include an association identifier, which is used to determine the second set of reference signal resources.

[0158] In some embodiments, the first information may include information about a second set of reference signal resources. This information may include, but is not limited to, time-domain resources, frequency-domain resources, number of ports, power information, and QCL assumptions corresponding to each second reference signal resource. The terminal can determine the second set of reference signal resources based on the information included in the first information.

[0159] In some embodiments, the first information may include an association identifier, which corresponds to a second set of reference signal resources. The terminal can determine the second set of reference signal resources based on the association identifier included in the first information. For example, the terminal can determine third information based on the association identifier. The third information may be configuration information, which includes information about the second set of reference signal resources.

[0160] In some embodiments, the first information further includes indication information of the reported quantity, which includes at least one of the following corresponding to at least one second reference signal resource in the second reference signal resource set: L1-RSRP; L1-SINR; L3-RSRP; L3-RSRQ; L3-RSSI; CSI; reference signal resource identifier.

[0161] In some embodiments, the network device may instruct the terminal on the amount of data to be reported, and the terminal sends a first report based on the network device's instruction.

[0162] In step S2102, the terminal determines the information of the second reference signal resource set based on the first information.

[0163] The first reference signal resource set includes first reference signal resources for measurement, and the first value of the first reference signal resources is used to obtain the second value of the second reference signal resources included in the second reference signal resource set.

[0164] In some embodiments, if the first information includes information about a second set of reference signal resources, the terminal can directly determine the information about the second set of reference signal resources based on the first information.

[0165] In some embodiments, the first information includes an association identifier, and the terminal can determine the second set of reference signal resources based on the association identifier.

[0166] 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.

[0167] In some embodiments, the terminal can measure the first reference signal resources included in the first reference signal resource set included in the first information to obtain a first value of the first reference signal resources; the terminal determines a second reference signal resource set based on the first information; the terminal predicts the second value of the second reference signal resources in the second reference signal resource set based on AI / ML and the first value of the first reference signal resources; and generates a first report based on the second value of the second reference signal resources. For example, the terminal inputs the measured value of the first reference signal resources into a trained AI model or ML model and outputs the predicted value of the second reference signal resources corresponding to the second cell.

[0168] Step S2103: The terminal sends a first report to the network device.

[0169] In some embodiments, the network device receives a first report sent by the terminal.

[0170] The first report includes the reported value corresponding to the reported quantity, which is obtained by measurement or prediction.

[0171] In some embodiments, the first report may also be referred to as the beam report.

[0172] In some embodiments, the first report may also be referred to as the CSI report.

[0173] In some embodiments, the first report may also be referred to as a Radio Resource Management (RRM) report.

[0174] In some embodiments, the first report may also be referred to as the L3 report.

[0175] For example, when the second value includes at least one of L1-RSRP and L1-SINR, the first report may be called a beamforming report or a CSI report. When the second value includes at least one of L3-RSRP, L3-RSRQ, and L3-RSSI, the first report may be called an RRM report or an L3 report. When the first value includes the CSI corresponding to the first reference signal resource, the first report may be called a CSI report.

[0176] In some embodiments, the first report may include a reported value corresponding to the reported quantity, and / or a resource identifier corresponding to at least one reference signal resource in the second set of reference signal resources.

[0177] In some embodiments, the reported value included in the first report corresponds to the reported quantity included in the first information. For example, if the reported quantity included in the first information includes L1-RSRP, then the terminal obtains the L1-RSRP value of the second reference signal resource and reports the L1-RSRP value of the second reference signal resource in the first report.

[0178] In some embodiments, the first set of reference signal resources may be the aforementioned set B, and the second set of reference signal resources may be the aforementioned set A.

[0179] In some embodiments, the terminal's prediction can be spatial beam prediction or temporal beam prediction.

[0213] In some embodiments, the terminal receives first configuration information, which includes information on a first reference signal resource set, at least one of a first cell identifier and a second cell identifier. The terminal determines information on a second reference signal resource set based on the first configuration information, wherein the first reference signal resource set corresponds to the first cell identifier and the second reference signal resource set corresponds to the second cell identifier.

[0214] In some embodiments, the terminal measures the measurement results corresponding to the reference signal resources in the first reference signal resource set, and obtains the prediction results corresponding to the second reference signal resource set based on the measurement results.

[0215] In some embodiments, the measurement results include at least one of the following corresponding to each reference signal resource in the first reference signal resource set: L1-RSRP, L1-SINR, L3-RSRP, L3-RSRQ, L3-RSSI, CSI (PMI, RI, CQI, etc.).

[0216] In some embodiments, the terminal obtains prediction results based on AI / ML functions / models and the measurement results.

[0217] In some embodiments, the prediction results include at least one of the following:

[0218] At least one of the following corresponds to at least one of the reference signal resources in the second reference signal resource set: including L1-RSRP, L1-SINR, L3-RSRP, L3-RSRQ, L3-RSSI, CSI (PMI, RI, CQI, etc.);

[0219] The top K reference signal resource identifiers in the second set of reference signal resources. Top K means the top K reference signal resources when sorted from strongest to weakest based on at least one of the following: L1-RSRP, L1-SINR, L3-RSRP, L3-RSRQ, L3-RSSI, CSI (PMI, RI, CQI, etc.).

[0220] In some embodiments, the first cell identifier is the identifier corresponding to the serving cell of the terminal.

[0221] In some embodiments, the second cell identifier is the identifier corresponding to the serving cell of the terminal, or the second cell identifier is the identifier corresponding to a cell other than the serving cell of the terminal.

[0222] In some embodiments, the second cell identifier is the identifier corresponding to the serving cell. That is, the terminal is configured with multiple serving cells, such as four serving cells. The serving cell identifier corresponding to each serving cell is the serving cell identifier (servingcellindex) 0, 1, 2, or 3. The ARFCN value (used to determine the frequency band corresponding to the cell from how many MHz to how many MHz) and the PCI of the serving cell are also configured to the terminal. Therefore, the second cell identifier only needs to indicate one of the servingcellindex 0, 1, 2, or 3.

[0223] In some embodiments, when a terminal is configured with multiple serving cells, there are two scenarios: carrier aggregation (CA) and dual connection (DC). DC is a special scenario where multiple serving cells correspond to different site locations. Furthermore, different serving cells can be divided into different cell groups, including a master cell group and a secondary cell group. When a second cell is also one of the serving cells, are there any restrictions between the second cell and the first cell? The following situations are given:

[0224] The first and second residential areas correspond to the same residential group; or...

[0225] The first and second communities correspond to different community groups.

[0226] When the above measurement results correspond to L1-RSRP or L1-SINR, i.e., in a beam measurement scenario, the terminal may be configured with one or more serving cell lists (i.e., the TCI state ID on serving cell 1 activated by a MAC CE can be applied to all serving cells in the serving cell list corresponding to serving cell 1), or the TCI state list configured by RRC on a serving cell can be used for other serving cells. Therefore, in this case, the first cell and the second cell are not in the same serving cell list, or the first cell and the second cell are not configured with this single configuration (the TCI state list configured by RRC on one serving cell can be used for another serving cell).

[0227] In some embodiments, the second cell identifier is the identifier of a cell other than the serving cell, i.e., a neighboring cell of the terminal. This neighboring cell can be on the same frequency as the first cell or on a different frequency. If it is on a different frequency, the carrier frequency information of the second cell also needs to be indicated, such as the range from a certain MHz to a certain MHz, or the ARFCN. The correspondence between the frequency bands corresponding to the ARFCN and the range from a certain MHz is defined by the protocol. The second cell identifier can be the PCI of the cell or a number in a list corresponding to the second cell. This list contains one or more second cells on one or more frequencies, and the number also corresponds to the PCI of the second cell identifier.

[0228] In some embodiments, the terminal determines a second reference signal resource set based on first configuration information, including the first configuration information including the second reference signal resource set, or the first configuration information including a first ID, and the terminal determines the second configuration information based on the first ID, wherein the second configuration information includes information about the second reference signal resource set.

[0229] The information of the reference signal resource set includes the time-domain resources, frequency-domain resources, number of ports, power information, QCL assumptions, etc., corresponding to each reference signal resource in the set.

[0230] In some embodiments, the first configuration information further includes the reported quantity, which includes at least one of the following:

[0231] At least one of the following corresponds to at least one of the reference signal resources in the second set of reference signal resources:

[0232] L1-RSRP, L1-SINR, L3-RSRP, L3-RSRQ, L3-RSSI, CSI (PMI, RI, CQI, etc.).

[0233] In some embodiments, the terminal sends a first report, the first report comprising at least one of the following:

[0234] The reported amount;

[0235] The reported values ​​include either actual measured values ​​or predicted values;

[0236] Resource identifier corresponding to at least one reference signal resource in the second set of reference signal resources.

[0237] In some embodiments, the second cell mentioned above may be one or more cells.

[0238] In some embodiments, neither the first cell nor the second cell is the serving cell of the terminal.

[0239] Wherein, the first cell and the second cell are the same cell, that is, the predicted value of the second reference signal resource set is obtained based on the measurement value of the first reference signal resource set of the same neighboring cell;

[0240] Alternatively, the first cell and the second cell may be different cells, that is, the predicted value of the second reference signal resource set of another neighboring cell is obtained based on the measurement value of the first reference signal resource set of one neighboring cell.

[0241] In some embodiments, the first reference signal resource set is similar to the aforementioned set B, and the second reference signal resource set is similar to the aforementioned set A, and includes spatial beam prediction and temporal beam prediction.

[0242] This disclosure proposes to predict the results of serving cells in different frequency bands, or to predict the results of neighboring cells, thereby further reducing reference signal resource overhead and reducing terminal measurements.

[0243] In the embodiments disclosed herein, some or all of the steps and their optional implementations may be arbitrarily combined with some or all of the steps in other embodiments, or may be arbitrarily combined with the optional implementations in other embodiments.

The functionality of some or all of the units or modules is achieved through the design of the logical relationships between the components within the circuit. In another implementation, the hardware circuit can be implemented using a programmable logic device (PLD).

All units or modules of the above device can be implemented entirely through processor-called software, entirely through hardware circuits, or partially through processor-called software with the remaining parts implemented through hardware circuits.

For example, the processor is a hardware circuit implemented using an application-specific integrated circuit (ASIC) or a programmable logic device (PLD), such as an FPGA. In a reconfigurable hardware circuit, the process of the processor loading a configuration document and configuring the hardware circuit can be understood as the process of the processor loading instructions to implement the functions of some or all of the above units or modules. Furthermore, it can also be a hardware circuit designed for artificial intelligence, which can be understood as an ASIC, such as a Neural Network Processing Unit (NPU), a Tensor Processing Unit (TPU), or a Deep Learning Processing Unit (DPU).
