[0137] One aspect of this disclosure proposes a method for supporting network energy conservation, which may include one or more of the following operations.

[0138] In some implementations, when deploying a cell, the cell can be divided into a first type of cell and a second type of cell.

[0140] ● Type II Cell: This can be a cell that does not require the transmission of a reference signal.

[0200] In some implementations, the fourth node sends a fifth message to the third node containing measurement results and / or synchronization information collected and / or generated and / or predicted and / or reported. Alternatively, after receiving a third message from the third node including a request for the collection and / or generation and / or prediction and / or reporting of measurement results and / or synchronization information, and / or after the fourth node sends a fourth message to the third node including a response to the collection and / or generation and / or prediction and / or reporting of measurement results and / or synchronization information (e.g., after the fourth node sends information to the third node regarding its ability to perform all and / or part of the collection and / or generation and / or prediction and / or reporting), the fourth node sends a fifth message containing the collected and / or generated and / or predicted and / or reported measurement results and / or synchronization information.

In still other implementations, for example, the fourth node can generate and / or predict synchronization information for UE access to one or more other cells based on measurement results from one or more cells. The fourth node can perform the aforementioned generation and / or prediction using artificial intelligence and / or machine learning models. For example, the collected and / or generated and / or predicted and / or reported measurement results and / or synchronization information can be the generated and / or predicted measurement results and / or synchronization information of one or more other cells. In some implementations, for example, after receiving the message, the third node can use the information in the message to perform cell selection and / or cell reselection, or make handover decisions based on the information, or access the corresponding cell using the synchronization information, etc. Alternatively, the third node can forward the information to other nodes, so that other nodes can use the information to perform cell selection and / or cell reselection, or make handover decisions based on the information, or access the corresponding cell using the synchronization information, etc. This scheme can reduce the cell measurements performed by the UE to obtain measurement results.

[0212] Example 4

[0213] One aspect of this disclosure proposes a method for supporting network energy conservation, which may include one or more of the following operations.

[0214] The fifth node sends a sixth message to the sixth node, containing a request for reference signal transmission and / or measurement results. The request asks the sixth node to transmit a reference signal (e.g., a reference signal corresponding to one or more cells in the sixth node) and / or report measurement results. The measurement results may correspond to the requested reference signal. In some implementations, for example, after the sixth node transmits the reference signal, the fifth node may configure the UE to measure the reference signal transmitted by the sixth node to obtain measurement results corresponding to the cells of the sixth node. The fifth node may use the measurement results of the cells of the sixth node and / or the measurement results of its own cells to train and / or infer and / or evaluate the performance of artificial intelligence and / or machine learning models. For example, in some implementations, the artificial intelligence and / or machine learning model may be a model that generates measurement results for one or more other cells based on the measurement results of one or more cells. In some implementations, the artificial intelligence and / or machine learning model may be a model that generates and / or predicts synchronization information for UE access to one or more other cells based on the measurement results of one or more cells. This scheme can reduce the measurements the UE performs on cells to obtain measurement results. For example, it can reduce the energy consumption of the UE for measurement. At the same time, this scheme can also reduce the transmission of reference signals by the cell, thereby achieving the effect of network energy saving.

[0251] In some implementations, the sixth node sends an eighth message containing measurement result information to the fifth node. Alternatively, after receiving a sixth message from the fifth node containing a request for reference signal transmission and / or measurement results, and / or after the sixth node sends a seventh message to the fifth node containing a response to reference signal transmission and / or measurement results (e.g., after the sixth node sends information to the fifth node regarding its ability to collect and / or report all and / or part of the measurement results), the sixth node sends the eighth message containing measurement result information to the fifth node. After obtaining the measurement result information, the fifth node can formulate mobility decisions and / or generate mobility-related information. The measurement result may be a measurement result corresponding to the requested reference signal. In some implementations, for example, after the sixth node sends a reference signal, the fifth node can configure the UE to measure the reference signal sent by the sixth node to obtain measurement results corresponding to the sixth node's cell. The fifth node can use the measurement results of the sixth node's cell and / or the measurement results of its own cell for training and / or inference of artificial intelligence and / or machine learning models and / or performance evaluation. For example, in some implementations, the artificial intelligence and / or machine learning model may be a model that generates measurement results for one or more other cells based on measurement results from one or more cells. In some implementations, the artificial intelligence and / or machine learning model may be a model that generates and / or predicts synchronization information for UE access to one or more other cells based on measurement results from one or more cells. This approach can reduce the measurements the UE performs on cells to obtain measurement results. For example, it can reduce the energy consumption of the UE for measurement. Simultaneously, this approach can also reduce the transmission of reference signals by cells, thereby achieving network energy saving.

[0263] Exemplary embodiments of this disclosure are further described below with reference to the accompanying drawings.

[0264] The text and accompanying drawings are provided by way of example only to aid in understanding this disclosure. They should not be construed as limiting the scope of this disclosure in any way. Although certain embodiments and examples have been provided, it will be apparent to those skilled in the art, based on the content disclosed herein, that changes may be made to the illustrated embodiments and examples without departing from the scope of this disclosure.

[0265] Figure 3 A schematic diagram of one aspect of a method for supporting network energy saving according to an embodiment of the present disclosure is shown. Specifically, Figure 3 This illustrates how cells can be categorized into Type 1 and Type 2 cells during deployment. For example... Figure 3 As shown, the first type of cells is represented by solid lines, such as first type cell 301, first type cell 302, first type cell 303, and first type cell 304. The second type of cells is represented by dashed lines, such as second type cells 311-314, second type cells 321-324, second type cells 331-334, and second type cells 341-344.

[0266] ●Type 1 Cell: This can be a cell that requires the transmission of reference signals. In some implementations, the reference signal here can be a reference signal used to acquire measurement results for the UE to perform cell selection and / or cell reselection and / or cell handover and / or cell access, and / or a reference signal used by the UE for downlink and / or uplink synchronization. The reference signal can include uplink and / or downlink reference signals. Type 1 cells can also be referred to as one or more of the following: non-data cell, synchronization cell, coverage cell, non-energy-saving cell, normal cell, reference signal cell, etc.

[0267] ● Type II Cell: This can be a cell that does not require the transmission of a reference signal. In some implementations, the reference signal here can be a reference signal used to acquire measurement results for the UE to perform cell selection and / or cell reselection and / or cell handover and / or cell access, and / or a reference signal used for the UE to perform downlink and / or uplink synchronization. The reference signal can include uplink and / or downlink reference signals. Type II cells can also be referred to as one or more of the following: data cell, asynchronous cell, capacity cell, energy-saving cell, abnormal cell, cell without reference signal, etc.

[0268] In some implementations, for example, a first-type cell can provide the same coverage area as one or more second-type cells. For example, such as... Figure 3 As shown, the first type cell 301 can provide coverage for the second type cells 311, 312, 313, and 314.

[0269] In other implementations, for example, a first type of cell can provide full coverage, and a second type of cell can provide capacity and / or data services within the coverage area of ​​the first type of cell and / or within a coverage area smaller than the coverage area of ​​the first type of cell. For example, such as Figure 3As shown, the first type of cell (e.g., first type cell 301, first type cell 302, first type cell 303, and first type cell 304) can provide full coverage. The coverage area of ​​each second type cell can be a part of the coverage area of ​​the corresponding first type cell. The second type cell can provide capacity and / or data services within its coverage area.

[0270] In some other implementations, for example, the coverage of the first type of cell is large (e.g., greater than a certain threshold and / or the coverage of the second type of cell), and the coverage of the second type of cell is small (e.g., less than a certain threshold and / or the coverage of the first type of cell).

[0271] In some other implementations, for example, the capacity of the first type of cell is small (e.g., less than a certain threshold and / or the capacity of the second type of cell), and the capacity of the second type of cell is large (e.g., greater than a certain threshold and / or the capacity of the first type of cell).

[0272] Figure 4A A schematic diagram of one aspect of a method for supporting network energy saving according to an embodiment of the present disclosure is shown. Specifically, Figure 4A This illustrates the process of two nodes exchanging cell status-related information.

[0273] In some implementations, for example, the first node may be a UE, and the second node may be a gNB, gNB-CU, gNB-DU, gNB CU-CP, gNB CU-UP, en-gNB, eNB, or ng-eNB. In other implementations, for example, the first node may be a gNB, gNB-CU, gNB CU-CP, en-gNB, eNB, or ng-eNB, and the second node may be a gNB, gNB-CU, gNB-DU, gNB CU-CP, gNB CU-UP, en-gNB, eNB, or ng-eNB. In still other implementations, for example, the first node may be an AMF, SMF, or MME, and the second node may be a gNB, gNB-CU, gNB CU-CP, en-gNB, eNB, or ng-eNB. In yet another implementation, for example, the first node may be a gNB, gNB-CU, gNB CU-CP, en-gNB, eNB, or ng-eNB, and the second node may be an AMF, SMF, or MME. Alternatively, for example, the first node is the primary node and the second node is the secondary node; for example, the first node is the secondary node and the second node is the primary node; for example, the first node is the source node and the second node is the target node; for example, the first node is the target node and the second node is the source node.

[0274] Step 401A: Optionally, the first node sends a cell state-related information request to the second node. This request may be used to request the second node to send cell state-related information concerning one or more cells of the second node and / or any other node. The cell state-related information request may be the aforementioned first message.

[0275] Step 402A: The second node sends cell status-related information to the first node. This message is used to inform the first node of cell status-related information concerning one or more cells of the second node and / or any other node. The cell status-related information may be the aforementioned second message.

[0276] Step 403A: Optionally, the first node sends a cell state-related information acknowledgment to the second node. This message can be used to indicate the first node's acknowledgment of the cell state-related information and / or to indicate the first node's acknowledgment of receiving the cell state-related information.

[0277] After receiving cell state-related information associated with one or more cells of a second node and / or any other node, the first node can formulate self-optimization decisions based on this information. It can also activate and / or deactivate cells of the second node and / or any other node based on the cell state-related information associated with one or more cells of the second node and / or any other node. In some implementations, for example, the first node can collect data by activating and / or deactivating cells. For example, the first node can activate cells of the second node and / or any other node to transmit reference signals to collect corresponding data and / or measurement results, etc. The collected data and / or measurement results can be used for training and / or inference and / or performance evaluation of artificial intelligence and / or machine learning models. In some implementations, for example, the artificial intelligence and / or machine learning model can be a model that generates measurement results for one or more other cells based on the measurement results of one or more cells. In some implementations, for example, the artificial intelligence and / or machine learning model can be a model that generates and / or predicts synchronization information for UE access to one or more other cells based on the measurement results of one or more cells.

[0279] In some implementations, for example, the seventh node can be gNB1 DU, the eighth node can be gNB1 CU, the ninth node can be gNB2 CU, and the tenth node can be gNB2 DU. In other implementations, for example, the seventh node can be a UE, the eighth node can be a gNB, gNB-CU, gNB-DU, gNB CU-CP, gNB CU-UP, en-gNB, eNB, or ng-eNB, the ninth node can be an AMF, SMF, or MME, and the tenth node can be a gNB, gNB-CU, gNB-DU, gNB CU-CP, gNB CU-UP, en-gNB, eNB, or ng-eNB. In still other implementations, for example, the seventh node can be gNB1, the eighth node can be gNB2, the ninth node can be gNB3, and the tenth node can be gNB4. In yet another implementation, for example, the seventh node can be node1 DU, the eighth node can be node1 CU, the ninth node can be node2 CU, and the tenth node can be node2 DU. The nodes can be the nodes of first-type cells or the nodes of second-type cells. Alternatively, for example, the seventh node is the auxiliary node, the eighth node is the primary node, the ninth node is the primary node, and the tenth node is the auxiliary node; for example, the seventh node is the source node DU, the eighth node is the source node CU, the ninth node is the target node CU, and the tenth node is the target node DU.

[0280] Step 401B: Optionally, the seventh node sends a cell status-related information request to the eighth node. This request can be used to request the eighth node and / or other nodes to send cell status-related information. The cell status-related information request can be the aforementioned first message.

[0281] Step 402B: Optionally, the eighth node sends a cell status-related information request to the ninth node.

In other implementations, for example, the seventh node can be a UE, the eighth node can be a gNB, gNB-CU, gNB-DU, gNB CU-CP, gNB CU-UP, en-gNB, eNB, or ng-eNB, the ninth node can be an AMF, SMF, or MME, and the tenth node can be a gNB, gNB-CU, gNB-DU, gNB CU-CP, gNB CU-UP, en-gNB, eNB, or ng-eNB. In still other implementations, for example, the seventh node can be gNB1, the eighth node can be gNB2, the ninth node can be gNB3, and the tenth node can be gNB4. In yet another implementation, for example, the seventh node can be node1 DU, the eighth node can be node1 CU, the ninth node can be node2 CU, and the tenth node can be node2 DU. The nodes can be the nodes of first-type cells or the nodes of second-type cells. Alternatively, for example, the seventh node is a secondary node, the eighth node is a primary node, the ninth node is a primary node, and the tenth node is a secondary node; for example, the seventh node is the source node (DU), the eighth node is the source node (CU), the ninth node is the target node (CU), and the tenth node is the target node (DU). Alternatively, for example, the seventh node is the DU of the node belonging to cell A of type 1, the eighth node is the CU of the node belonging to cell A of type 1, the ninth node is the CU of the node and / or its parent node belonging to cell B of type 2, and the tenth node is the DU of the node and / or its parent node belonging to cell B of type 2.

[0349] Step 500F: Optionally, this step can be referred to Figure 4B process.

[0350] Step 501F: The seventh node and / or the eighth node send a reference signal to the UE. This reference signal may be a reference signal corresponding to one or more cells of the seventh node and / or the eighth node.

[0351] Step 502F: UE measures the reference signal.

[0352] Step 503F: The UE performs cell selection and / or cell reselection. For example, in this example, assume the UE selects the first cell in the seventh node and / or the eighth node based on one or more measurement results.

[0353] Step 504F: The UE sends the measurement results to the eighth node. The measurement results may be measurement results of reference signals corresponding to one or more cells (e.g., the first cell, etc.) in the seventh and / or eighth nodes. One or more cells in the seventh and / or eighth nodes may be first-type cells. The measurement results can be sent via RRC messages. For example, they can be sent via RRC establishment request and / or RRC recovery request messages.

[0354] Step 505F: The eighth node collects and / or generates and / or predicts measurement results and / or synchronization information. In some implementations, for example, measurement results and / or synchronization information for the second type of cell can be generated and / or predicted based on the measurement results of the first type of cell. In some implementations, for example, the generated and / or predicted measurement results and / or synchronization information can be obtained by machine learning and / or artificial intelligence models, or by mathematical algorithms, etc. For example, the measurement results and / or synchronization information for the second type of cell can be obtained through one or more of the following: measurement results of the first type of cell, cell state-related information of the first type of cell, cell state-related information of the second type of cell, etc.

[0355] Step 506F: The eighth node selects another (e.g., more suitable) Type I and / or Type II cell for the UE based on the collected and / or generated and / or predicted measurement results and / or synchronization information. The eighth node may send the cell identifier and / or synchronization information related to the cell selected by the eighth node that can be used by the UE for access. The synchronization information may be the aforementioned fifth message. The cell identifier and / or synchronization information related to the cell that can be used by the UE for access can be sent via RRC messages. For example, it can be sent via RRC establishment and / or recovery and / or release messages.

[0356] More specifically, in some implementations, in step 505F, the eighth node may generate and / or predict and / or determine one or more second measurement results and / or synchronization information related to second type cells in the ninth and / or tenth nodes based on one or more first measurement results received from the UE that are related to the first type cells in the seventh and / or eighth nodes. In step 506F, the eighth node may select one or more second type cells from the second type cells in the ninth and / or tenth nodes for UE access based on the one or more second measurement results. For example, the eighth node may select the second type cell with the best corresponding second measurement result for UE access, or make the selection based on any other rule.

[0357] Step 507F: The UE establishes and / or resumes an RRC connection with the target cell selected for access. In some implementations, for example, the UE can access the target cell based on the synchronization information obtained in step 505F.

[0358] Figure 5G A schematic diagram of one aspect of a method for supporting network energy saving according to an embodiment of the present disclosure is shown. Specifically, Figure 5G The process of generating and / or predicting measurement results and / or synchronization information through interaction between nodes is illustrated. In some implementations, because the second type of cell may not transmit reference signals (e.g., reference signals used by the UE for cell selection and / or cell reselection and / or cell handover and / or cell access, etc.), the UE cannot select to access and / or camp on a second type of cell. This solution can address the problem of how the UE accesses and / or camps on a cell in scenarios where first and second type cells are co-deployed. This solution can achieve network energy saving and can also support UE mobility while supporting network energy saving.

[0359] In some implementations, for example, the seventh node can be gNB1 DU, the eighth node can be gNB1 CU, the ninth node can be gNB2 CU, and the tenth node can be gNB2 DU. In other implementations, for example, the seventh node can be a UE, the eighth node can be a gNB, gNB-CU, gNB-DU, gNB CU-CP, gNB CU-UP, en-gNB, eNB, or ng-eNB, the ninth node can be an AMF, SMF, or MME, and the tenth node can be a gNB, gNB-CU, gNB-DU, gNB CU-CP, gNB CU-UP, en-gNB, eNB, or ng-eNB. In still other implementations, for example, the seventh node can be gNB1, the eighth node can be gNB2, the ninth node can be gNB3, and the tenth node can be gNB4. In yet another implementation, for example, the seventh node can be node1 DU, the eighth node can be node1 CU, the ninth node can be node2 CU, and the tenth node can be node2 DU. The nodes can be the nodes of first-type cells or the nodes of second-type cells. Alternatively, for example, the seventh node is a secondary node, the eighth node is a primary node, the ninth node is a primary node, and the tenth node is a secondary node; for example, the seventh node is the source node DU, the eighth node is the source node CU, the ninth node is the target node CU, and the tenth node is the target node DU. Alternatively, for example, the seventh node is the DU of the node belonging to cell A of type two, the eighth node is the CU of the node belonging to cell A of type two, the ninth node is the CU of the node belonging to and / or the node belonging to cell B of type one, and the tenth node is the CU of the node belonging to and / or the node belonging to cell B of type one.

[0360] Step 500G: Optionally, this step can be referred to Figure 4B process.

[0361] Step 501G: The seventh node and / or the eighth node send cell status-related information to the UE. The cell status-related information may be the aforementioned second message. The cell status-related information may include cell status-related information of first-type cells and / or second-type cells. For example, if the cells managed by the seventh node and / or the eighth node are first-type cells, the seventh node and / or the eighth node may send cell status-related information of the first-type cells they manage to the UE, and / or may provide cell status-related information of one or more second-type cells corresponding to the coverage area. The cell status-related information of the second-type cells can be obtained through step 500G. Alternatively, for example, if the cells managed by the seventh node and / or the eighth node are second-type cells, the seventh node and / or the eighth node may send cell status-related information of the second-type cells they manage to the UE, and / or may provide cell status-related information of one or more first-type cells corresponding to the coverage area. The cell status-related information of the first-type cells can be obtained through step 500G. The sending may be a broadcast. The information may be sent via RRC messages. In some embodiments, for example, it may be sent via system information block messages.

[0362] Step 502G: The node sends a reference signal to the UE. For example, the node of the first type cell may send the reference signal to the UE. For example, if the cell managed by the seventh node and / or the eighth node is a first type cell, then the seventh node and / or the eighth node sends a reference signal to the UE.

[0363] Step 503G: UE measures the reference signal.

[0364] Step 504G: The UE collects and / or generates and / or predicts measurement results and / or synchronization information. In some implementations, for example, measurement results and / or synchronization information for a second type of cell can be generated and / or predicted based on the measurement results of a first type of cell. In some implementations, for example, the generated and / or predicted measurement results and / or synchronization information can be obtained by machine learning and / or artificial intelligence models, or by mathematical algorithms, etc. For example, the measurement results and / or synchronization information for the second type of cell can be obtained through one or more of the following: measurement results of the first type of cell, cell state-related information of the first type of cell, cell state-related information of the second type of cell, etc.

[0365] Step 505G: The UE performs cell selection and / or cell reselection. For example, in this example, assume the UE selects a cell in the seventh node and / or the eighth node based on one or more measurement results. In some implementations, the UE may perform cell selection and / or cell reselection among all cells corresponding to all these measurement results based on a first measurement result and / or a second measurement result generated and / or predicted based on the first measurement result.

[0366] Step 506G: The UE establishes and / or resumes an RRC connection with the (re)selected cell. In some implementations, for example, the UE can access the target cell based on the synchronization information obtained in step 504G.

[0367] Figure 6A A schematic diagram of one aspect of a method for supporting network energy saving according to an embodiment of the present disclosure is shown. Specifically, Figure 6A The process of exchanging reference signal transmission and / or measurement result information between two nodes is illustrated.

[0368] In some implementations, for example, the fifth node may be a gNB, gNB-CU, gNB-DU, gNB CU-CP, gNB CU-UP, en-gNB, eNB, or ng-eNB, and the sixth node may be a UE. In other implementations, for example, the fifth node may be a UE, and the sixth node may be a gNB, gNB-CU, gNB-DU, gNB CU-CP, gNB CU-UP, en-gNB, eNB, or ng-eNB. In still other implementations, for example, the fifth node may be a gNB, gNB-CU, gNB CU-CP, en-gNB, eNB, or ng-eNB, and the sixth node may be a gNB, gNB-CU, gNB-DU, gNB CU-CP, gNB CU-UP, en-gNB, eNB, or ng-eNB. In yet another implementation, for example, the fifth node may be an AMF, SMF, or MME, and the sixth node may be a gNB, gNB-CU, gNB CU-CP, en-gNB, eNB, or ng-eNB. In some other implementations, for example, the fifth node can be a gNB, gNB-CU, gNB CU-CP, en-gNB, eNB, or ng-eNB, and the sixth node can be an AMF, SMF, or MME. Alternatively, the fifth node can be a primary node and the sixth node a secondary node; the fifth node can be a secondary node and the sixth node a primary node; the fifth node can be a source node and the sixth node a target node; the fifth node can be a target node and the sixth node a source node; the fifth node can be the node where a first-type cell is located and the sixth node is the node where a second-type cell is located; the fifth node can be the node where a second-type cell is located and the sixth node is the node where a first-type cell is located; or the fifth node can be a gNB CU and the sixth node can be a gNB DU. The gNB can be either the node where a first-type cell is located or the node where a second-type cell is located.

[0369] Step 601A: Optionally, the fifth node sends a reference signal transmission and / or measurement result request to the sixth node. This request can be used to request the sixth node to send a reference signal and / or report measurement results. The reference signal transmission and / or measurement result request can be the aforementioned sixth message.

[0370] Step 602A: Optionally, the sixth node sends a reference signal transmission and / or measurement result response to the fifth node. This message can be used to inform the fifth node whether the sixth node can perform all and / or part of the measurement result collection and / or reporting and / or reference signal transmission. The reference signal transmission and / or measurement result response can be the aforementioned seventh message.

[0371] Step 603A: The sixth node transmits a reference signal and / or collects measurement results.

[0372] Step 604A: The sixth node sends the collected measurement results to the fifth node. The measurement results may be the aforementioned eighth message.

[0373] After obtaining the measurement results, the fifth node can formulate mobility decisions and / or generate mobility-related information. The measurement results can be those corresponding to a requested reference signal. In some implementations, for example, after the sixth node sends a reference signal, the fifth node can configure the UE to measure the reference signal sent by the sixth node to obtain measurement results corresponding to the sixth node's cell. The fifth node can use the measurement results of the sixth node's cell and / or its own cell to train and / or infer and / or evaluate the performance of artificial intelligence and / or machine learning models. For example, in some implementations, the artificial intelligence and / or machine learning model can be a model that generates measurement results for one or more other cells based on the measurement results of one or more cells. In some implementations, the artificial intelligence and / or machine learning model can be a model that generates and / or predicts synchronization information for the UE to access one or more other cells based on the measurement results of one or more cells. This scheme can reduce the measurements the UE performs on cells to obtain measurement results. For example, it can reduce the energy consumption of the UE for measurement. Simultaneously, this scheme can also reduce the transmission of reference signals by cells, thereby achieving network energy saving.

[0374] Figure 6B A schematic diagram of one aspect of a method for supporting network energy saving according to an embodiment of the present disclosure is shown. Specifically, Figure 6B The process of exchanging reference signal transmission and / or measurement result information between two nodes is illustrated.

[0375] In some implementations, for example, the fifth node may be a gNB, gNB-CU, gNB-DU, gNB CU-CP, gNB CU-UP, en-gNB, eNB, or ng-eNB, and the sixth node may be a UE. In other implementations, for example, the fifth node may be a UE, and the sixth node may be a gNB, gNB-CU, gNB-DU, gNB CU-CP, gNB CU-UP, en-gNB, eNB, or ng-eNB. In still other implementations, for example, the fifth node may be a gNB, gNB-CU, gNB CU-CP, en-gNB, eNB, or ng-eNB, and the sixth node may be a gNB, gNB-CU, gNB-DU, gNB CU-CP, gNB CU-UP, en-gNB, eNB, or ng-eNB. In yet another implementation, for example, the fifth node may be an AMF, SMF, or MME, and the sixth node may be a gNB, gNB-CU, gNB CU-CP, en-gNB, eNB, or ng-eNB. In some other implementations, for example, the fifth node can be a gNB, gNB-CU, gNB CU-CP, en-gNB, eNB, or ng-eNB, and the sixth node can be an AMF, SMF, or MME. Alternatively, the fifth node can be a primary node and the sixth node a secondary node; the fifth node can be a secondary node and the sixth node a primary node; the fifth node can be a source node and the sixth node a target node; the fifth node can be a target node and the sixth node a source node; the fifth node can be the node where a first-type cell is located and the sixth node is the node where a second-type cell is located; the fifth node can be the node where a second-type cell is located and the sixth node is the node where a first-type cell is located; or the fifth node can be a gNB CU and the sixth node can be a gNB DU. The gNB can be either the node where a first-type cell is located or the node where a second-type cell is located.

[0376] Step 601B: The fifth node sends a reference signal transmission and / or measurement result request to the sixth node. This request can be used to request the sixth node to send a reference signal and / or report measurement results. The reference signal transmission and / or measurement result request can be the aforementioned sixth message.

This message informs the fifth node whether the sixth node can collect and / or report all and / or transmit reference signals. The reference signal transmission and / or measurement result response may be the aforementioned seventh message.

[0378] Step 603B: The sixth node sends a reference signal.

[0379] In some implementations, for example, after the sixth node transmits a reference signal, the fifth node can configure the UE to measure the reference signal transmitted by the sixth node to obtain measurement results corresponding to the sixth node's cell. The fifth node can use the measurement results of the sixth node's cell and / or the measurement results of its own cell to train and / or infer and / or evaluate the performance of an artificial intelligence and / or machine learning model. For example, in some implementations, the artificial intelligence and / or machine learning model can be a model that generates measurement results for one or more other cells based on the measurement results of one or more cells. In some implementations, the artificial intelligence and / or machine learning model can be a model that generates and / or predicts synchronization information for the UE to access one or more other cells based on the measurement results of one or more cells. This scheme can reduce the measurements the UE performs on cells to obtain measurement results. For example, it can reduce the energy consumption of the UE for measurement. At the same time, this scheme can also reduce the transmission of reference signals by cells, thereby achieving network energy saving.

In still other implementations, for example, the seventh node can be gNB1, the eighth node can be gNB2, the ninth node can be gNB3, and the tenth node can be gNB4. In yet another implementation, for example, the seventh node can be node1 DU, the eighth node can be node1 CU, the ninth node can be node2 CU, and the tenth node can be node2 DU. The nodes can be the nodes of first-type cells or the nodes of second-type cells. Alternatively, for example, the seventh node is a secondary node, the eighth node is a primary node, the ninth node is a primary node, and the tenth node is a secondary node; for example, the seventh node is the source node (DU), the eighth node is the source node (CU), the ninth node is the target node (CU), and the tenth node is the target node (DU).

The reference signal measurement configuration may be a measurement configuration for reference signals corresponding to a second-type cell, and / or a measurement configuration for reference signals corresponding to a first-type cell. In some embodiments, for example, the cell managed by the seventh node and / or the eighth node is a second-type cell. In other embodiments, for example, the cell managed by the seventh node and / or the eighth node is a first-type cell.

[0391] Step 609C: The UE measures the reference signal. In some implementations, for example, the UE can perform the reference signal measurement based on the reference signal measurement configuration sent by the eighth node.

[0395] After obtaining the measurement results, the seventh and / or eighth nodes can formulate mobility decisions and / or generate mobility-related information. The measurement results may correspond to a requested reference signal. In some implementations, for example, after the ninth and / or tenth nodes send a reference signal, the seventh and / or eighth nodes can configure the UE to measure the reference signal sent by the ninth and / or tenth nodes to obtain measurement results corresponding to the cells of the ninth and / or tenth nodes. The seventh and / or eighth nodes can use the measurement results corresponding to the cells of the ninth and / or tenth nodes and / or the measurement results corresponding to their own cells to train and / or infer and / or evaluate the performance of artificial intelligence and / or machine learning models. For example, in some implementations, the artificial intelligence and / or machine learning model may be a model that generates measurement results for one or more other cells based on the measurement results of one or more cells. In some implementations, for example, the artificial intelligence and / or machine learning model may be a model that generates and / or predicts synchronization information for UE access to one or more other cells based on the measurement results of one or more cells. This approach can reduce the number of measurements the UE needs to perform on cells to obtain measurement results. For example, this can reduce the energy consumption of the UE for measurements.

In some embodiments, for example, the cell managed by the seventh node and / or the eighth node is a second-type cell. In other embodiments, for example, the cell managed by the seventh node and / or the eighth node is a first-type cell.

[0407] Step 609D: The UE measures the reference signal. In some implementations, for example, the UE can perform reference signal measurement based on the reference signal measurement configuration sent by the seventh node.

The seventh and / or eighth nodes can use the measurement results corresponding to the cells of the ninth and / or tenth nodes and / or the measurement results corresponding to their own cells to train and / or infer and / or evaluate the performance of artificial intelligence and / or machine learning models. For example, in some implementations, the artificial intelligence and / or machine learning model may be a model that generates measurement results for one or more other cells based on the measurement results of one or more cells. In some implementations, for example, the artificial intelligence and / or machine learning model may be a model that generates and / or predicts synchronization information for UE access to one or more other cells based on the measurement results of one or more cells. This approach can reduce the number of measurements the UE needs to perform on cells to obtain measurement results. For example, this can reduce the energy consumption of the UE for measurements.
