Description

Measurement methods and devices

[0001] This application claims priority to Chinese Patent Application No. 202411990548.5, filed with the State Intellectual Property Office of China on December 28, 2024, entitled "Measuring Method and Apparatus", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of communications, and more particularly to measurement methods and apparatus. Background Technology

[0003] A measurement gap (or measurement interval) is a specific time interval agreed upon by the network side and the terminal device for measurement. When a terminal device needs to perform measurements on different frequency points or different system frequency points, the base station configures a measurement gap for the terminal device. During the measurement gap, the terminal device and the serving cell suspend uplink and downlink data transmission. After the measurement gap ends, the terminal device resumes data transmission and reception.

[0004] Because data transmission between the terminal equipment and the serving cell is suspended during the measurement gap, it affects the data transmission of the terminal equipment, leading to a decrease in the terminal equipment's throughput. Therefore, how to improve the throughput of the terminal equipment during inter-frequency measurement is an urgent problem to be solved. Summary of the Invention

[0005] This application provides a measurement method and apparatus that can improve the throughput of terminal equipment during heterogeneous frequency measurement.

[0006] In a first aspect, embodiments of this application provide a measurement method that can be executed by a terminal device. Unless otherwise specified, the term "terminal device" in this application can refer to the terminal device itself, or a component in the terminal device (e.g., a communication module, processor, circuit, chip, or chip system), or a logic module or software that can implement all or part of the functions of the terminal device. The method includes: receiving first configuration information, the first configuration information indicating a measurement time interval or a layer 1 beam-level measurement result, the measurement time interval being the time interval between the measurement time of the serving cell of the terminal device and the measurement time of the target neighbor cell, the target neighbor cell and the serving cell having different frequency points, the layer 1 beam-level measurement result including a layer 1 beam-level sampling result or a layer 1 beam-level filtering result, the layer 1 beam-level filtering result being obtained by layer 1 filtering processing of the layer 1 beam-level sampling result; determining a first measurement result according to the first configuration information, the first measurement result including the measurement result of the target neighbor cell, the first measurement result being used to determine a first channel correlation, the first channel correlation being the correlation between a first channel and a second channel corresponding to the first measurement result, the first channel being the radio channel between the terminal device and the serving cell, the second channel being the radio channel between the terminal device and the target neighbor cell; and sending the first measurement result.

[0007] Based on this scheme, the terminal device can determine the measurement result of the target neighbor cell (i.e., the first measurement result) to be reported to the network device based on the first configuration information configured for it by the network device. This allows the network device to use the measurement result of the target neighbor cell to determine the channel correlation between the serving cell and the target neighbor cell (i.e., the first channel correlation, which is the correlation between the first channel and the second channel corresponding to the first measurement result; the first channel is the radio channel between the terminal device and the serving cell, and the second channel is the radio channel between the terminal device and the target neighbor cell). The first configuration information indicates the measurement time interval or the Layer 1 beam-level measurement result. The measurement time interval is the time interval between the measurement time of the serving cell of the terminal device and the measurement time of the target neighbor cell. The target neighbor cell and the serving cell have different frequency points. The Layer 1 beam-level measurement result includes the Layer 1 beam-level sampling result or the Layer 1 beam-level filtering result. The Layer 1 beam-level filtering result is obtained by filtering the Layer 1 beam-level sampling result.

[0008] It is understandable that, since the channel state is constantly changing, if the time interval between the measurement time of the serving cell and the measurement time of the target neighboring cell is too large, it may lead to a decrease in the accuracy of channel correlation. Therefore, it is advisable to set a time interval threshold (i.e., measurement time interval) to avoid affecting the accuracy of channel correlation due to an excessively large measurement time interval.

[0009] Furthermore, measurements are typically performed by Layer 1, where Layer 1 obtains its beam-level sampling results. Layer 3 then filters these multiple Layer 1 beam-level sampling results to obtain its own beam-level filtered results. Currently, the Layer 3 beam-level filtered results are usually used as the measurement results. However, the Layer 3 filtering process involves time averaging, and measurement time is a crucial factor in determining correlation in this application. This can easily affect the accuracy of the correlation determined based on the Layer 3 beam-level filtered results. Therefore, this application directly uses the Layer 1 beam-level sampling results as the measurement results, or it filters the Layer 1 sampling results to eliminate interference, obtaining the Layer 1 beam-level filtered results and using them as the measurement results. This avoids the Layer 3 filtering process affecting the accuracy of the correlation.

[0010] Furthermore, since the higher the channel correlation value, the higher the accuracy of inter-frequency prediction (i.e., predicting the measurement results of the target neighbor cell through the measurement results of the serving cell), it is considered that inter-frequency prediction can be used when the first channel correlation value is large, thereby reducing or lowering the use of measurement gaps and improving the throughput of terminal devices.

[0011] In one possible design, before receiving the first configuration information, the method further includes: sending capability information, which indicates that the terminal device supports the reporting of beam-level measurement results of layer 1.

[0012] Based on this possible design, the terminal device can first report whether it supports reporting Layer 1 beam-level measurement results; thus, the network device can send the first configuration information to the terminal device if it supports reporting Layer 1 beam-level measurement results. This avoids the terminal device being unable to report the measurement results of the target neighbor cell due to not supporting the reporting of Layer 1 beam-level measurement results, which would prevent the network device from determining the first channel correlation.

[0013] In one possible design, the capability information also indicates the relationship between the prediction accuracy and correlation of the first model, which is located within the terminal device and is used to predict the measurement results of the target neighboring area.

[0014] Based on this possible design, the terminal device can also report the accuracy that the first model can achieve in its predictions under different correlations. This allows the network device to determine whether it needs to configure relevant parameters for model training for the terminal device based on the prediction accuracy, avoiding performance degradation in inter-frequency prediction due to low prediction accuracy, which would affect cell handover performance.

[0015] In one possible design, the method further includes: receiving first indication information, the first indication information indicating whether to start a first model, the first indication information being determined based on a first channel correlation, the first model being located within the terminal device, the first model being used to predict the measurement results of a target neighboring cell; if the first model is started, receiving second indication information, the second indication information indicating whether to shut down the first model, the second indication information being determined based on a second channel correlation; wherein, the second channel correlation is the correlation between the first channel corresponding to the second measurement result and the second channel, the measurement time of the second measurement result is after the first model is started, and the second measurement result includes the measurement results of the target neighboring cell.

[0016] Based on this possible design, when inter-frequency prediction is initiated (i.e., the first model is enabled) according to the correlation of the first channel, the network device can continuously monitor the correlation between the first channel and the second channel (e.g., determine the correlation of the second channel); thereby determining whether to disable the first model (i.e., indicate the second indication information) and ensuring the accuracy of inter-frequency prediction.

[0017] In one possible design, before receiving the second indication information, the method further includes: receiving second configuration information, the second configuration information indicating the monitoring interval GAP; determining a second measurement result based on the second configuration information; and sending the second measurement result.

[0018] In one possible design, before receiving the second indication information, the method further includes: receiving second configuration information, the second configuration information indicating the monitoring GAP; determining a second measurement result based on the second configuration information; determining a second channel correlation based on the second measurement result; and sending the second channel correlation.

[0019] Based on the two possible designs mentioned above, the correlation of the second channel can be determined by the terminal device and communicated to the network device, or it can be determined by the network device, providing different implementation methods for the correlation of the second channel.

[0020] In one possible design, sending a second channel correlation includes sending a request message for requesting the first model to be turned on or off.

[0021] In one possible design, the request information is used to request the activation of the first model, including: requesting the deactivation of the measurement gap or the extension of the measurement gap period, the measurement gap being used to determine the measurement results of the target neighboring cell, and the terminal device being within the measurement gap.

[0022] Based on this possible design, it is understandable that during inter-frequency measurement, the terminal device typically needs to measure the target neighboring cell within the measurement gap; and the process of monitoring whether to turn off the first model is as follows: the terminal device measures the target neighboring cell within a monitoring gap, and then determines the second channel correlation based on the measurement results. If the second channel correlation is small, then the first model is considered to be turned off.

[0023] Specifically, when a terminal device is in a measurement gap, if monitoring is initiated, the measurement gap needs to be activated to initiate the monitoring gap; therefore, the terminal device can implicitly indicate this by requesting to activate the measurement gap.

[0024] Considering that the monitoring gap is used to monitor whether the correlation between the first and second channels has changed significantly compared to the correlation of the first channel, and that channel state changes are usually small over a short period of time, a longer period can be set for the monitoring gap. In other words, the monitoring gap is a measurement gap with a longer period. Therefore, when the terminal device is in a measurement gap, the measurement gap can be extended to become a monitoring gap, thus saving the resource overhead of configuring the monitoring gap.

[0025] In one possible design, the second configuration information also indicates the calculation method of the first channel correlation or the second channel correlation, the first indication information is determined based on the first channel correlation, the measurement object corresponding to the first measurement result or the second measurement result, or the first accuracy rate; wherein the calculation method of the first channel correlation and the second channel correlation is the same, the measurement object corresponding to the first measurement result and the second measurement result is the same, and the first accuracy rate is the prediction accuracy rate of the first model expected by the serving cell.

[0026] Based on this possible design, when the devices for calculating the first channel correlation and the devices for calculating the second channel correlation are different, the device for calculating the second channel correlation can measure and calculate the second channel correlation based on the same parameters as the first channel correlation. This avoids the difference between the first channel correlation and the second channel correlation being too large or too small due to the influence of factors other than channel state, which could easily lead to errors in the judgment of whether inter-frequency prediction is turned off, thus affecting cell handover performance.

[0027] In one possible design, when the first channel correlation is greater than a first threshold, the first indication information indicates that the first model is started; when the first channel correlation is less than or equal to the first threshold, the first indication information indicates that the first model is turned off or not started.

[0028] In one possible design, when the second channel correlation is greater than the first threshold, the second indication information indicates that the first model should not be turned off; when the second channel correlation is less than or equal to the first threshold, the second indication information indicates that the first model should be turned off.

[0029] Combining the two possible designs above, since the greater the channel correlation, the higher the accuracy of inter-frequency prediction, a threshold (i.e., the first threshold) can be preset. When the channel correlation is greater than the threshold, inter-frequency prediction is started (i.e., the first model is turned on); when the channel correlation is less than or equal to the threshold, inter-frequency prediction is turned off (i.e., the first model is turned off), so as to ensure the accuracy of inter-frequency prediction.

[0030] In one possible design, the first measurement results also include the measurement results of the serving cell.

[0031] In one possible design, the first configuration information also indicates the measurement object, and the measurement pair includes the target neighboring cell and / or the serving cell.

[0032] In one possible design, the measurement object includes the target neighboring cell, comprising: the measurement object includes one or more beams of the target neighboring cell; correspondingly, the measurement result of the target neighboring cell includes the measurement result of one or more beams of the target neighboring cell.

[0033] In one possible design, the measurement object includes the serving cell, including: the measurement object includes one or more beams of the serving cell; thus, when the first measurement result also includes the measurement result of the serving cell, the first measurement result also includes the measurement result of the serving cell, including: the first measurement result also includes the measurement result of one or more beams of the serving cell.

[0034] Secondly, embodiments of this application provide a measurement method that can be executed by a network device. Unless otherwise specified, the term "network device" in this application can refer to the network device itself, or a component within the network device (e.g., a communication module, processor, circuit, chip, or chip system), or a logic module or software that can implement all or part of the functions of the network device. The method includes: sending first configuration information, the first configuration information indicating a measurement time interval or a layer 1 beam-level measurement result, the measurement time interval being the time interval between the measurement time of the serving cell of the terminal device and the measurement time of the target neighbor cell, the target neighbor cell and the serving cell having different frequency points, the layer 1 beam-level measurement result including a layer 1 beam-level sampling result or a layer 1 beam-level filtering result, the layer 1 beam-level filtering result being obtained by layer 1 filtering processing of the layer 1 beam-level sampling result; receiving a first measurement result, the first measurement result being determined based on the first configuration information, the first measurement result including the measurement result of the target neighbor cell; and determining a first channel correlation based on the first measurement result, the first channel correlation being the correlation between a first channel and a second channel corresponding to the first measurement result, the first channel being the radio channel between the terminal device and the serving cell, and the second channel being the radio channel between the terminal device and the target neighbor cell.

[0035] Based on this scheme, the network device can configure first configuration information for the terminal device, enabling the terminal device to determine the measurement results (i.e., the first measurement results) of the target neighbor cell to report to the network device based on the first configuration information. Then, the network device can use the measurement results of the target neighbor cell to determine the channel correlation (i.e., the first channel correlation, which is the correlation between the first channel and the second channel corresponding to the first measurement result; the first channel is the radio channel between the terminal device and the serving cell, and the second channel is the radio channel between the terminal device and the target neighbor cell). The first configuration information indicates the measurement time interval or the layer 1 beam-level measurement results. The measurement time interval is the time interval between the measurement time of the terminal device's serving cell and the measurement time of the target neighbor cell. The target neighbor cell and the serving cell have different frequency points. The layer 1 beam-level measurement results include layer 1 beam-level sampling results or layer 1 beam-level filtering results. The layer 1 beam-level filtering results are obtained by layer 1 filtering of the layer 1 beam-level sampling results.

[0036] It is understandable that, since the channel state is constantly changing, if the time interval between the measurement time of the serving cell and the measurement time of the target neighboring cell is too large, it may lead to a decrease in the accuracy of channel correlation. Therefore, it is advisable to set a time interval threshold (i.e., measurement time interval) to avoid affecting the accuracy of channel correlation due to an excessively large measurement time interval.

[0037] Furthermore, measurements are typically performed by Layer 1, where Layer 1 obtains its beam-level sampling results. Layer 3 then filters these multiple Layer 1 beam-level sampling results to obtain its own beam-level filtered results. Currently, the Layer 3 beam-level filtered results are usually used as the measurement results. However, the Layer 3 filtering process involves time averaging, and measurement time is a crucial factor in determining correlation in this application. This can easily affect the accuracy of the correlation determined based on the Layer 3 beam-level filtered results. Therefore, this application directly uses the Layer 1 beam-level sampling results as the measurement results after obtaining them, or Layer 1 filters these sampling results to eliminate interference, obtaining the Layer 1 beam-level filtered results and using them as the measurement results. This avoids the Layer 3 filtering process affecting the accuracy of the correlation.

[0038] Furthermore, since the higher the channel correlation value, the higher the accuracy of inter-frequency prediction (i.e., predicting the measurement results of the target neighbor cell through the measurement results of the serving cell), it is considered that inter-frequency prediction can be used when the first channel correlation value is large, thereby reducing or lowering the use of measurement gaps and improving the throughput of terminal devices.

[0039] In one possible design, before sending the first configuration information, the method further includes sending capability information, which indicates that the terminal device supports the reporting of beam-level measurement results of layer 1.

[0040] In one possible design, the capability information also indicates the relationship between the prediction accuracy and correlation of the first model, which is located within the terminal device and is used to predict the measurement results of the target neighboring area.

[0041] In one possible design, the method further includes: sending first indication information based on a first channel correlation, the first indication information indicating whether to start a first model, the first model being located within a terminal device, the first model being used to predict the measurement results of a target neighboring cell; and, if the first model is started, sending second indication information based on a second channel correlation, the second indication information indicating whether to shut down the first model; wherein, the second channel correlation is the correlation between the first channel and the second channel corresponding to the second measurement result, the measurement time of the second measurement result is after the first model is started, and the second measurement result includes the measurement results of the target neighboring cell.

[0042] In one possible design, before sending the second indication information based on the second channel correlation, the method further includes: sending second configuration information indicating a monitoring interval GAP; receiving a second measurement result determined based on the monitoring GAP; and determining the second channel correlation based on the second measurement result.

[0043] In one possible design, before sending the second indication information based on the second channel correlation, the method further includes: sending second configuration information, the second configuration information indicating the monitoring GAP; receiving the second channel correlation, the second channel correlation being determined based on a second measurement result, the second measurement result being determined based on the monitoring GAP.

[0044] In one possible design, receiving a second channel correlation includes: receiving request information for requesting to turn a first model on or off; determining second indication information based on the second channel correlation includes: determining the second indication information based on the request information.

[0045] In one possible design, the request information is used to request the activation of the first model, including: requesting the deactivation of the measurement gap or the extension of the measurement gap period, the measurement gap being used to determine the measurement results of the target neighboring cell, and the terminal device being within the measurement gap.

[0046] In one possible design, the second configuration information also indicates the calculation method of the first channel correlation or the second channel correlation, the first indication information is determined based on the first channel correlation, the measurement object corresponding to the first measurement result or the second measurement result, or the first accuracy rate; wherein the calculation method of the first channel correlation and the second channel correlation is the same, the measurement object corresponding to the first measurement result and the second measurement result is the same, and the first accuracy rate is the prediction accuracy rate of the first model expected by the serving cell.

[0047] In one possible design, when the first channel correlation is greater than a first threshold, the first indication information indicates that the first model is started; when the first channel correlation is less than or equal to the first threshold, the first indication information indicates that the first model is turned off or not started.

[0048] In one possible design, when the correlation of the second channel is greater than the first threshold, the second indication information indicates that the first model should not be turned off.

[0049] When the correlation of the second channel is less than or equal to the first threshold, the second indication information indicates that the first model is turned off.

[0050] In one possible design, the first measurement results also include the measurement results of the serving cell.

[0051] In one possible design, the first configuration information also indicates the measurement object, and the measurement pair includes the target neighboring cell and / or the serving cell.

[0052] In one possible design, the measurement object includes the target neighboring cell, comprising: the measurement object includes one or more beams of the target neighboring cell; correspondingly, the measurement result of the target neighboring cell includes the measurement result of one or more beams of the target neighboring cell.

[0053] In one possible design, the measurement object includes the serving cell, including: the measurement object includes one or more beams of the serving cell; thus, when the first measurement result also includes the measurement result of the serving cell, the first measurement result also includes the measurement result of the serving cell, including: the first measurement result also includes the measurement result of one or more beams of the serving cell.

[0054] The technical effects of any possible design in the second aspect can be referenced to the technical effects of the corresponding design in the first aspect, and will not be elaborated here.

[0055] Thirdly, embodiments of this application provide a measurement method, which can be executed by a terminal device. Unless otherwise specified, "terminal device" in this application can refer to the terminal device itself, a component within the terminal device (e.g., a communication module, processor, circuit, chip, or chip system), or a logic module or software capable of implementing all or part of the terminal device's functions. The method includes: receiving first configuration information, the first configuration information indicating one or more of the following: a measurement time interval, the precision of a channel correlation value, or a calculation method for the channel correlation; the measurement time interval being the time interval between the measurement time of the serving cell of the terminal device and the measurement time of a target neighboring cell, wherein the target neighboring cell and the serving cell have different frequency points; determining a first measurement result based on the first configuration information, the first measurement result including the measurement result of the target neighboring cell; determining a first channel correlation based on the first measurement result, the first channel correlation being the correlation between a first channel and a second channel corresponding to the first measurement result, the first channel being the wireless channel between the terminal device and the serving cell, and the second channel being the wireless channel between the terminal device and the target neighboring cell; and transmitting the first channel correlation.

[0056] Based on this scheme, the terminal device can determine the measurement result (i.e., the first measurement result) of the target neighboring cell based on the first configuration information configured for it by the network device. Furthermore, it can also use the measurement result of the target neighboring cell to determine the channel correlation (i.e., the first channel correlation, which is the correlation between the first channel and the second channel corresponding to the first measurement result; the first channel is the radio channel between the terminal device and the serving cell, and the second channel is the radio channel between the terminal device and the target neighboring cell). The first configuration information indicates one or more of the following: the measurement time interval, the accuracy of the channel correlation value, or the calculation method of the channel correlation. The measurement time interval is the time interval between the measurement time of the serving cell of the terminal device and the measurement time of the target neighboring cell, and the target neighboring cell and the serving cell have different frequency points.

[0057] Understandably, since channel states are constantly changing, a large time interval between the measurement time of the serving cell and the measurement time of the target neighboring cell may reduce the accuracy of channel correlation. Therefore, setting a time interval threshold (i.e., the measurement time interval) can be considered to avoid affecting the accuracy of channel correlation due to an excessively large measurement time interval. And / or, network devices can also configure the precision of channel correlation values ​​for terminal devices, i.e., to what decimal place the channel correlation value can be accurate. For example, network devices can consider setting a higher precision for the channel correlation value to improve the accuracy of the first channel correlation calculated by the terminal device. And / or, network devices can consider configuring the terminal device with the channel correlation calculation methods it supports, avoiding configuring calculation methods that the terminal device does not support, which would prevent the terminal device from calculating the first channel correlation.

[0058] Furthermore, since the higher the channel correlation value, the higher the accuracy of inter-frequency prediction (i.e., predicting the measurement results of the target neighbor cell through the measurement results of the serving cell), it is considered that inter-frequency prediction can be used when the first channel correlation value is large, thereby reducing or decreasing the use of measurement gaps and improving the throughput of terminal devices.

[0059] In one possible design, the first configuration information further indicates at least one set of measurement objects, any one of which includes a first beam and a second beam, the first beam belonging to the serving cell and the second beam belonging to the target neighboring cell, and the first channel correlation includes the correlation between the first beam and the second beam.

[0060] Based on this possible design, network devices can configure terminal devices with at least one set of measurement objects whose correlation needs to be calculated. Thus, when calculating channel correlation, the terminal devices do not need to calculate the channel correlation of different beams one by one. Instead, they can calculate based on the at least one set of measurement objects, thereby reducing complexity.

[0061] In one possible design, before receiving the first configuration information, the method further includes: sending capability information, the capability information indicating whether the terminal device supports correlation calculation; and determining the first channel correlation based on the first measurement result, including: when the terminal device supports correlation calculation, determining the first channel correlation based on the first measurement result.

[0062] Based on this possible design, the terminal device can first report whether it supports correlation calculation; thus, if the terminal device supports correlation calculation, the network device can send it the first configuration information. This avoids the terminal device being unable to calculate the first channel correlation, or failing to calculate it, due to its lack of support for correlation calculation.

[0063] In one possible design, the capability information indicates that the terminal device supports one or more of the following: the type of input information required to calculate channel correlation, a first quantity, a measurement time interval, a channel correlation threshold, a channel correlation calculation method, or a measurement period; wherein, the type of input information includes any one of: layer 1 beam-level filtering results, layer 1 beam-level sampling results, or layer 3 beam-level filtering results, wherein the layer 1 beam-level filtering results are obtained by layer 1 filtering of layer 1 beam-level sampling results; the first quantity is the number of groups of measurement objects, each group of measurement objects includes a first beam and a second beam, the first beam belongs to the serving cell, the second beam belongs to the target neighboring cell, and the first channel correlation includes the correlation between the first beam and the second beam; the channel correlation threshold is the maximum or minimum value of the channel correlation, and the measurement period is the time period to which the measurement result belongs.

[0064] Based on this possible design, the terminal device can report the parameters it supports when calculating channel correlation. The network device can then configure appropriate first configuration information for the terminal device based on the parameters reported by the terminal device, thus avoiding the terminal device being unable to calculate the first channel correlation or the accuracy of the calculated first channel correlation being reduced due to the terminal device configuring unsupported parameters.

[0065] In one possible design, the capability information also indicates the relationship between the prediction accuracy and correlation of the first model, which is located within the terminal device and is used to predict the measurement results of the target neighboring area.

[0066] In one possible design, the method further includes: when the first channel correlation is greater than a first threshold, using a first model to predict the measurement results of the target neighboring cell; receiving second configuration information, the second configuration information indicating a monitoring interval GAP; determining a second measurement result based on the second configuration information, the measurement time of the second measurement result being after the first model is started, the second measurement result including the measurement results of the target neighboring cell; determining a second channel correlation based on the second measurement result, the second channel correlation being the correlation between the first channel and the second channel corresponding to the second measurement result; determining whether to shut down the first model based on the second channel correlation; and sending the second channel correlation.

[0067] In one possible design, the method further includes: receiving first indication information, the first indication information indicating whether to start a first model, the first indication information being determined based on a first channel correlation, the first model being located within the terminal device, and the first model being used to predict the measurement results of a target neighboring cell; if the first model is started, receiving second indication information, the second indication information indicating whether to shut down the first model, the second indication information being determined based on a second channel correlation; wherein, the second channel correlation is the correlation between the first channel and the second channel corresponding to the second measurement result, the measurement time of the second measurement result is after the first model is started, and the second measurement result includes the measurement results of the target neighboring cell.

[0068] In one possible design, before receiving the second indication information, the method further includes: receiving second configuration information, the second configuration information indicating the monitoring GAP; determining a second measurement result based on the second configuration information; and sending the second measurement result.

[0069] In one possible design, before receiving the second indication information, the method further includes: receiving second configuration information, the second configuration information indicating the monitoring GAP; determining a second measurement result based on the second configuration information; determining a second channel correlation based on the second measurement result; and sending the second channel correlation.

[0070] In one possible design, sending a second channel correlation includes sending a request message for requesting the first model to be turned on or off.

[0071] In one possible design, when the first channel correlation is greater than a first threshold, the first indication information indicates that the first model is started; when the first channel correlation is less than or equal to the first threshold, the first indication information indicates that the first model is turned off or not started.

[0072] In one possible design, when the second channel correlation is greater than the first threshold, the second indication information indicates that the first model should not be turned off; when the second channel correlation is less than or equal to the first threshold, the second indication information indicates that the first model should be turned off.

[0073] In one possible design, the second configuration information indicates the monitoring GAP, including: the second configuration information indicates deactivating the measurement GAP or extending the period of the measurement GAP, the measurement GAP being used to determine the measurement results of the target neighboring cell, and the terminal device being within the measurement GAP.

[0074] In one possible design, the first measurement results also include the measurement results of the serving cell.

[0075] In one possible design, the measurement results of the target neighbor cell include the measurement results of one or more beams of the target neighbor cell; similarly, the measurement results of the serving cell include the measurement results of one or more beams of the serving cell.

[0076] The technical effects of the aforementioned possible designs in the third aspect can be referenced to the technical effects of the corresponding designs in the first aspect, and will not be elaborated further here.

[0077] Fourthly, embodiments of this application provide a measurement method that can be executed by a network device. Unless otherwise specified, "network device" in this application can refer to the terminal device itself, a component within the network device (e.g., a communication module, processor, circuit, chip, or chip system), or a logic module or software capable of implementing all or part of the network device's functions. The method includes: sending first configuration information, which indicates one or more of the following: a measurement time interval, the precision of a channel correlation value, or a calculation method for the channel correlation. The measurement time interval is the time interval between the measurement time of the serving cell of the terminal device and the measurement time of a target neighboring cell, where the target neighboring cell and the serving cell have different frequency points; and receiving a first channel correlation, where the first configuration information is determined based on the first channel correlation. The first channel correlation is the correlation between a first channel and a second channel corresponding to a first measurement result, where the first channel is the wireless channel between the terminal device and its serving cell, and the second channel is the wireless channel between the terminal device and the target neighboring cell.

[0078] Based on this scheme, the network device can configure first configuration information for the terminal device, thereby enabling the terminal device to determine the measurement results (i.e., the first measurement results) of the target neighboring cell based on the first configuration information. Furthermore, the measurement results of the target neighboring cell can be used to determine the channel correlation (i.e., the first channel correlation, which is the correlation between the first channel and the second channel corresponding to the first measurement results; the first channel is the radio channel between the terminal device and the serving cell, and the second channel is the radio channel between the terminal device and the target neighboring cell). The first configuration information indicates one or more of the following: measurement time interval, channel correlation value precision, or channel correlation calculation method. The measurement time interval is the time interval between the measurement time of the terminal device's serving cell and the measurement time of the target neighboring cell, and the target neighboring cell and the serving cell have different frequency points.

[0079] Understandably, since channel states are constantly changing, a large time interval between the measurement time of the serving cell and the measurement time of the target neighboring cell may reduce the accuracy of channel correlation. Therefore, setting a time interval threshold (i.e., the measurement time interval) can be considered to avoid affecting the accuracy of channel correlation due to an excessively large measurement time interval. And / or, network devices can also configure the precision of channel correlation values ​​for terminal devices, i.e., to what decimal place the channel correlation value can be accurate. For example, network devices can consider setting a higher precision for the channel correlation value to improve the accuracy of the first channel correlation calculated by the terminal device. And / or, network devices can consider configuring the terminal device with the channel correlation calculation methods it supports, avoiding configuring calculation methods that the terminal device does not support, which would prevent the terminal device from calculating the first channel correlation.

[0080] Furthermore, since the higher the channel correlation value, the higher the accuracy of inter-frequency prediction (i.e., predicting the measurement results of the target neighbor cell through the measurement results of the serving cell), it is considered that inter-frequency prediction can be used when the first channel correlation value is large, thereby reducing or decreasing the use of measurement gaps and improving the throughput of terminal devices.

[0081] In one possible design, the first configuration information also indicates at least one set of measurement objects, any one of which includes a first beam and a second beam, the first beam belonging to the serving cell and the second beam belonging to the target neighboring cell, and the first channel correlation includes the correlation between the first beam and the second beam.

[0084] In one possible design, the capability information also indicates the relationship between the prediction accuracy and correlation of the first model, which is located within the terminal device and is used to predict the measurement results of the target neighboring area.

[0086] In one possible design, the method further includes the following before sending the second indication information:

[0087] Send second configuration information, which indicates the monitoring gap; receive second measurement results, which are obtained within the monitoring gap.

[0088] In one possible design, the method further includes the following before sending the second indication information:

[0089] Send second configuration information, which indicates the monitoring gap; receive second channel correlation, which is used to determine the second measurement result of the second channel correlation obtained within the monitoring gap.

[0090] In one possible design, receiving a second channel correlation includes receiving request information for requesting to turn the first model on or off.

[0091] In one possible design, the second configuration information indicates the monitoring GAP, including: the second configuration information indicates deactivating the measurement GAP or extending the period of the measurement GAP, the measurement GAP being used to determine the measurement results of the target neighboring cell, and the terminal device being within the measurement GAP.

[0092] In one possible design, when the first channel correlation is greater than a first threshold, the first indication information indicates that the first model is started; when the first channel correlation is less than or equal to the first threshold, the first indication information indicates that the first model is turned off or not started.

[0093] In one possible design, when the second channel correlation is greater than the first threshold, the second indication information indicates that the first model should not be turned off; when the second channel correlation is less than or equal to the first threshold, the second indication information indicates that the first model should be turned off.

[0095] In one possible design, the measurement results of the target neighbor cell include the measurement results of one or more beams of the target neighbor cell; similarly, the measurement results of the serving cell include the measurement results of one or more beams of the serving cell.

[0096] The technical effects of any possible design in the fourth aspect can be referenced from the technical effects of the corresponding design in the third aspect above, and will not be elaborated here.

[0097] Fifthly, embodiments of this application provide a measurement method, which can be executed by a first network device. Unless otherwise specified, the "first network device" in this application can refer to the first network device itself, a component within the first network device (e.g., a communication module, processor, circuit, chip, or chip system), or a logic module or software capable of implementing all or part of the functions of the first network device. For example, the first network device can be the network device to which a neighboring cell of a terminal device belongs. The method includes: sending first request information, the first request information indicating one or more of the following: a measurement result acquisition period, a measurement period, and the number of samples of the measurement result; the first request message is used to request a first measurement result, the first measurement result including the measurement result of the terminal device, the measurement result of the terminal device including the measurement result of the serving cell of the terminal device and / or the measurement result of the neighboring cell of the terminal device, the serving cell and the neighboring cell having different frequency points; receiving the first measurement result; and determining a first channel correlation based on the first measurement result, the first channel correlation being the correlation between a first channel and a second channel corresponding to the first measurement result, the first channel being the wireless channel between the terminal device and the serving cell, and the second channel being the wireless channel between the terminal device and the neighboring cell.

[0098] Based on this scheme, the measurement results of the serving cell and / or the serving cell can be obtained through the interaction between the network devices of the neighboring cell (such as the first network device) and the network devices of the serving cell (i.e., the second network device); wherein the neighboring cell and the serving cell have different frequency points. Specifically, when the network devices interact, one or more of the following can be considered: measurement results obtained within a certain measurement period, measurement results obtained within a certain measurement result acquisition period, or a sufficient number of measurement result samples.

[0099] Understandably, since channel conditions are constantly changing, excessively long measurement and / or measurement result acquisition periods can reduce the accuracy of channel correlation. Therefore, it's advisable to consider calculating the first channel correlation based on measurement results obtained within a specific measurement period and those obtained within a specific result acquisition period. This avoids the accuracy of channel correlation being affected by excessively long measurement time intervals. Furthermore, insufficient sample size for measurement results can also impact the accuracy of channel correlation. Ensuring a sufficient sample size is crucial to prevent this issue from affecting the accuracy of channel correlation.

[0100] Furthermore, since the higher the channel correlation value, the higher the accuracy of inter-frequency prediction (i.e., predicting the measurement results of the target neighbor cell through the measurement results of the serving cell), it is considered that inter-frequency prediction can be used when the first channel correlation value is large, thereby reducing or decreasing the use of measurement gaps and improving the throughput of terminal devices.

[0102] Based on this possible design, it is understood that the channel correlation is determined based on the measurement results of neighboring cells and the measurement results of the serving cell. Therefore, when the measurement results of the terminal device do not include the measurement results of neighboring cells, the terminal device also needs to determine the measurement results of neighboring cells in order to calculate the first channel correlation.

[0103] In one possible design, the method further includes: sending first indication information based on a first channel correlation, the first indication information indicating whether to start a first model, the first model being located within a terminal device, the first model being used to predict measurement results of neighboring cells; and, if the first model is started, sending second indication information based on a second channel correlation, the second indication information indicating whether to shut down the first model; wherein, the second channel correlation is the correlation between the first channel and the second channel corresponding to the second measurement result, the measurement time of the second measurement result is after the first model is started, and the second measurement result includes the measurement results of the terminal device.

[0109] In one possible design, when the first channel correlation is greater than a first threshold, the first indication information indicates that the first model is started; when the first channel correlation is less than or equal to the first threshold, the first indication information indicates that the first model is turned off or not started.

[0110] In one possible design, when the second channel correlation is greater than the first threshold, the second indication information indicates that the first model should not be turned off; when the second channel correlation is less than or equal to the first threshold, the second indication information indicates that the first model should be turned off.

Specifically, when the network devices interact, one or more of the following can be considered: measurement results obtained within a certain measurement period, measurement results obtained within a certain measurement result acquisition period, or a sufficient number of measurement result samples.

[0114] Understandably, since channel conditions are constantly changing, excessively long measurement and / or measurement result acquisition periods can reduce the accuracy of channel correlation. Therefore, it's advisable to consider calculating the first channel correlation based on measurement results obtained within a specific measurement period and those obtained within a specific result acquisition period. This avoids the accuracy of channel correlation being affected by excessively long measurement time intervals. Furthermore, insufficient sample size for measurement results can also impact the accuracy of channel correlation. Ensuring a sufficient sample size is crucial to prevent this issue from affecting the accuracy of channel correlation.

[0115] Furthermore, since the higher the channel correlation value, the higher the accuracy of inter-frequency prediction (i.e., predicting the measurement results of the target neighbor cell through the measurement results of the serving cell), it is considered that inter-frequency prediction can be used when the first channel correlation value is large, thereby reducing or decreasing the use of measurement gaps and improving the throughput of terminal devices.

[0223] Before describing the embodiments of this application, the technical terms involved in the embodiments of this application will be described.

[0224] Cell handover: In 5th generation (5G) or new radio (NR) systems, the cell handover process may include the steps shown in Figure 1 below:

[0225] S101. The source base station of the terminal device (also known as the serving base station before handover) can send measurement configuration information to the terminal device. Correspondingly, the terminal device receives the measurement configuration information from the source base station.

[0226] S102. The terminal device measures the object to be measured based on the measurement configuration information.

[0227] Optionally, if the measurement result of a measurement object obtained by the terminal device within a certain period of time meets the measurement reporting conditions, the terminal device shall report a measurement report.

[0228] The measurement results are obtained by measuring at layer 1 (such as the physical (PHY) layer) and filtering at layer 3 (such as the radio resource control (RRC) layer).

[0229] S103. The terminal device sends a measurement report to the source base station. Correspondingly, the source base station receives the measurement report from the terminal device.

[0230] For example, the measurement quantities include measurement ID, measurement quantities of the serving cell, and measurement quantities of neighboring cells of the serving cell. The measurement quantities of the cell may include: physical cell identity (PCI), cell reference signal measurement results, beam reference signal measurement results, etc.

[0231] S104. After receiving the measurement report, the source base station determines the target cell based on the measurement report.

[0232] For example, the source base station evaluates the measurement results in the measurement report and then determines the target cell.

[0233] S105. The source base station sends a handover request to the target base station of the target cell. Correspondingly, the target base station receives the handover request from the source base station.

[0234] For example, a handover request may include information required for handover, such as the ID of the target cell.

[0235] S106. Access control is performed on the target base station.

[0236] Optionally, access control can be understood as determining whether terminal devices are supported to access the target base station.

[0237] When supporting terminal devices to access the target base station, step S107 is executed:

[0238] S107. The target base station sends a handover confirmation message to the source base station. Correspondingly, the source base station receives the handover confirmation message from the target base station.

[0239] For example, the handover confirmation information includes configuration information related to the target cell (such as the target cell ID).

[0240] S108. The source base station sends an RRC reconfiguration message (handover command) to the terminal device. Correspondingly, the terminal device receives the RRC reconfiguration message from the source base station.

[0241] S109. The terminal device performs a handover based on the RRC reconfiguration message.

[0242] For example, the terminal device can perform RRC reconfiguration based on the RRC reconfiguration information. After the RRC reconfiguration is completed, the terminal device sends a message indicating successful RRC reconfiguration to the target base station. Correspondingly, the target base station receives the message from the terminal device indicating successful RRC reconfiguration. At this point, the handover on the radio access network (RAN) side of the terminal device can be considered successful.

[0243] Optionally, in this application, "handover" generally refers to the handover between base station control and terminal equipment control in RRC connection state, cell changes, etc.

[0244] Measurement configuration information: Measurement configuration information is used in the measurement reporting process during cell handover; measurement configuration information is carried in RRC reconfiguration information.

[0245] For example, the measurement configuration information may include the contents shown in Table 1 below:

[0246] Table 1

[0247] Each measurement configuration has a unique identifier (measId), and each measurement object has a unique ID (measObjectId). To ensure accurate and complete measurement of the SSB beam under each cell, when configuring the measurement object, the base station, in addition to indicating the time-frequency position and subcarrier spacing of the reference signal, also indicates the timing position and duration of SMTC (Site Management Center Control), i.e., the start time of reference signal measurement. The SMTC configuration effectively instructs the terminal equipment on the time window for searching the reference signal, which can be either an SSB or CSI-RS. Each reporting configuration has a unique identifier (reportConfigId). The reporting configuration (also known as the measurement reporting condition configuration) can be event-triggered or period-triggered. Event-triggered reporting configurations include various event categories and threshold values, the duration for meeting the trigger conditions, the measurement quantities to be reported, and the reference signal type. Various event definitions include events such as A1, A2, A3, A4, A5, A6, B1, and B2. Period-triggered reporting configurations include the reporting period, reference signal type, measurement quantities to be reported, and a whitelist of available cells.

[0248] The Measurement GAP is a time interval specifically agreed upon by the network side and the terminal device for measurement. During the Measurement GAP, the terminal device and the serving cell suspend uplink and downlink data transmission. After the Measurement GAP ends, the terminal device resumes data transmission and reception. When the terminal device needs to measure frequency points or frequency points of different systems, the base station determines that a Measurement GAP has been configured for the terminal device. For example, the Measurement GAP configuration (measgapconfig) field may include the fields in Table 2 below:

[0249] Table 2

[0250] Based on the relevant concepts of measurement gaps, the measurements performed by the terminal device during the measurement gap can be understood as inter-frequency measurements performed by the terminal device. For ease of description, "measurements performed by the terminal device during the measurement gap" will be referred to as "inter-frequency measurements" below, and will not be elaborated further here.

[0251] For example, during inter-frequency measurement, the measurement object of the terminal device is a neighboring cell with a different frequency from the serving cell. In this case, the measurement of the measurement object by the terminal device in step S102 can be replaced by the terminal device performing inter-frequency prediction on the measurement object. Specifically, during inter-frequency measurement, the source base station can send a handover request (HO REQUEST) to the base station to which the measurement object (i.e., the inter-frequency neighboring cell) belongs. Further, the base station instructs the measurement object to send confirmation information (such as a handover request acknowledgement information (HO REQUEST ACK)) to the terminal device. After receiving the confirmation information, the source base station sends a handover configuration to the terminal device, so that the terminal device can switch from the source base station to the base station to which the measurement object belongs based on the handover configuration, and then measure the neighboring cell to obtain the measurement result.

[0252] The process of a terminal device "switching from the source base station to the base station of the neighboring cell in the different frequency range" can also be understood as: the terminal device performs "inter-frequency switching"; that is, the terminal device needs to perform inter-frequency switching during inter-frequency measurement.

[0253] Because the data transmission between the terminal device and the serving cell is suspended during inter-frequency measurement, it will affect the data transmission of the terminal device (such as reducing the throughput of the terminal device). Therefore, in Release 19 (R19), the 3rd Generation Partnership Project (3GPP) protocol proposes to use artificial intelligence (AI) models to predict the measurement results of inter-frequency neighboring cells with the measurement results of the serving cell as input, thereby reducing or eliminating the inter-frequency measurement process, reducing the time of data transmission interruption for the terminal device, and improving the throughput of the terminal device.

[0254] The process by which the terminal device “predicts the measurement results of inter-frequency neighboring cells based on the AI ​​model” can also be referred to as “inter-frequency prediction”. For ease of description, the process by which the terminal device “predicts the measurement results of inter-frequency neighboring cells based on the AI ​​model” will be uniformly referred to as “inter-frequency prediction process” in the following embodiments. This will be explained uniformly here and will not be repeated.

[0255] Because the wireless channel environments of the serving cell and neighboring cells differ, the accuracy of inter-frequency prediction may be low. However, simulations of inter-frequency measurement results and prediction results reveal that the higher the correlation between the wireless channel environments of the serving cell and neighboring cells, the higher the accuracy of inter-frequency prediction. Therefore, enabling inter-frequency prediction when the channel correlation between the serving cell and neighboring cells is high can be considered to reduce the data transmission interruption time of terminal devices and improve their throughput. In other words, whether to enable inter-frequency prediction depends entirely on the value of channel correlation; therefore, a decrease in the accuracy of channel correlation will lead to a decrease in the performance of inter-frequency prediction. Thus, improving the accuracy of channel correlation between the serving cell and neighboring cells is an urgent problem to be solved.

[0256] Based on this, this application provides a measurement method in which a terminal device can determine the measurement result (i.e., the first measurement result) of a target neighbor cell to report to the network device based on first configuration information configured for it by the network device. This allows the network device to use the measurement result of the target neighbor cell to determine the channel correlation (i.e., the first channel correlation, which is the correlation between the first channel and the second channel corresponding to the first measurement result, where the first channel is the radio channel between the terminal device and the serving cell, and the second channel is the radio channel between the terminal device and the target neighbor cell). The first configuration information indicates a measurement time interval or a layer 1 beam-level measurement result. The measurement time interval is the time interval between the measurement time of the serving cell of the terminal device and the measurement time of the target neighbor cell. The target neighbor cell and the serving cell have different frequency points. The layer 1 beam-level measurement result includes a layer 1 beam-level sampling result or a layer 1 beam-level filtering result. The layer 1 beam-level filtering result is obtained by layer 1 filtering of the layer 1 beam-level sampling result.

[0257] It is understandable that, since the channel state is constantly changing, if the time interval between the measurement time of the serving cell and the measurement time of the target neighboring cell is too large, it may lead to a decrease in the accuracy of channel correlation. Therefore, it is advisable to set a time interval threshold (i.e., measurement time interval) to avoid affecting the accuracy of channel correlation due to an excessively large measurement time interval.

[0258] Furthermore, measurements are typically performed by Layer 1, where Layer 1 obtains its beam-level sampling results. Layer 3 then filters these multiple Layer 1 beam-level sampling results to obtain its own beam-level filtered results. Currently, the Layer 3 beam-level filtered results are usually used as the measurement results. However, the Layer 3 filtering process involves time averaging, and measurement time is a crucial factor in determining correlation in this application. This can easily affect the accuracy of the correlation determined based on the Layer 3 beam-level filtered results. Therefore, this application directly uses the Layer 1 beam-level sampling results as the measurement results after obtaining them, or it filters the Layer 1 sampling results to eliminate interference, obtaining the Layer 1 beam-level filtered results and using them as the measurement results. This avoids the Layer 3 filtering process affecting the accuracy of the correlation.

[0259] Furthermore, since the higher the channel correlation value, the higher the accuracy of inter-frequency prediction (i.e., predicting the measurement results of the target neighbor cell through the measurement results of the serving cell), it is considered that inter-frequency prediction can be used when the first channel correlation value is large, thereby reducing or lowering the use of measurement gaps and improving the throughput of terminal devices.

[0260] The embodiments of this application will now be described in detail with reference to the accompanying drawings.

[0261] The measurement method provided in this application can be used in any communication system, including 3GPP systems such as Long Term Evolution (LTE), 5G mobile communication systems, LTE and 5G hybrid networks, New Radio (NR) systems, NR vehicle-to-everything (V2X) systems, device-to-device (D2D) communication systems, machine-to-machine (M2M) communication systems, Internet of Things (IoT), narrowband Internet of Things (NB-IoT), enhanced mobile broadband (eMBB), ultra-reliable and low-latency communication (URLLC), enhanced machine-type communication (eMTC), and various types of future communication systems.

Terminal devices can also be user stations, mobile stations, remote stations, remote terminal devices, mobile terminal devices, user terminal devices, wireless communication devices, user agents, user devices, cellular phones, cordless phones, session initiation protocol (SIP) phones, wireless local loop (WLL) stations, personal digital assistants (PDAs), handheld devices with wireless communication capabilities, computing devices, processing devices connected to wireless modems, in-vehicle devices, wearable devices, terminal devices in the Internet of Things (IoT), home appliances, virtual reality (VR) terminals, augmented reality (AR) terminals, customer-premises equipment (CPE), light user equipment (Light UE), reduced capability user equipment (REDCAP UE), wireless terminals in industrial control, wireless terminals in autonomous driving, wireless terminals in telemedicine, wireless terminals in smart grids, wireless terminals in smart cities, and wireless terminals in smart homes. Wireless terminals in the home, vehicles with vehicle-to-everything (V2X) communication capabilities, intelligent connected vehicles, vehicle devices (such as vehicle devices, vehicle modules, vehicle chips, on-board units (OBUs) or telematics boxes (T-BOXs), etc.), drones with UAV-to-UAV (U2U) communication capabilities, terminal devices in future networks, or terminal devices in future evolved public land mobile networks (PLMNs) are not restricted.

[0266] Terminal equipment can also be referred to as a system, subscriber unit (SU), subscriber station (SS), mobile station (MB), mobile station (Mobile), remote station (RS), access point (AP), remote terminal (RT), access terminal (AT), user terminal (UT), user agent (UA), user device (UD), or UE.

[0267] Optionally, the network device can be any device deployed in the access network capable of wireless communication with terminal devices. It can also be a chip or chip system configurable within the aforementioned device, a logical node or module, or a function implemented in software. Its main responsibilities include air interface-side wireless physical control, resource scheduling, wireless resource management, quality of service management, data compression and encryption, wireless access control, and mobility management. Specifically, the network device can be either a wired access device or a wireless access device.

[0268] For example, a network device can consist of one or more access network (AN) / radio access network (RAN) nodes. AN / RAN nodes can be various types of base stations, such as: satellite base stations, evolved Node Bs (gNBs), transmission reception points (TRPs), evolved Node Bs (eNBs), radio network controllers (RNCs), Node Bs (NBs), base station controllers (BSCs), base transceiver stations (BTSs), home base stations (e.g., home evolved Node Bs, or home Node Bs (HNBs), macro base stations, micro base stations, pico base stations, small cells, relay stations, balloon stations, drone stations, wireless backhaul nodes, base band units (BBUs), or wireless fidelity (Wi-Fi) access points (APs), etc. It is understood that network devices can be terrestrial devices or non-terrestrial devices (such as satellites, drones, high-altitude communication equipment, etc.). Furthermore, in communication systems employing different wireless access technologies, the names of network devices with base station functions may differ, and this application does not impose any restrictions on this.

[0269] Optionally, the roles of network devices and terminal devices can be relative. For example, in Figure 2, terminal 120i and terminal 120j, since terminal 120j needs to access the wireless access network device 110a through terminal 120i, terminal 120i can be configured as a wireless access network device relative to terminal 120j; while relative to wireless access network device 110a, terminal 120i is a terminal device, meaning that wireless access network device 110a and terminal 120i communicate via a wireless air interface protocol. Optionally, network device 110a and terminal 120i can also communicate via a network device-to-network device interface protocol. In this case, terminal 120i also acts as a wireless access network device relative to network device 110a. Optionally, communication between network devices and terminal devices, between network devices, or between terminal devices can be conducted via licensed spectrum, unlicensed spectrum, or both licensed and unlicensed spectrum simultaneously. Optionally, communication between network devices and terminal devices, between network devices, or between terminal devices can be conducted using spectrum below 6 GHz, or using spectrum above 6 GHz, or simultaneously using spectrum below 6 GHz and spectrum above 6 GHz. The embodiments of this application do not limit the spectrum resources used for wireless communication.

[0270] In another example, the network equipment may include a BBU and a remote radio unit (RRU). The BBU and RRU can be located in different places; for example, the RRU can be moved remotely to a high-traffic area, while the BBU is located in the central equipment room. The BBU and RRU can also be located in the same equipment room. The BBU and RRU can also be different components under the same rack.

[0271] In another example, the network device can be a device that includes centralized unit (CU) nodes, distributed unit (DU) nodes, or both CU and DU nodes. Specifically, when the first network element is a terminal device, the second network element is a DU.

[0272] One CU can be associated with one or more DUs. As shown in Figure 3, base stations #1 and #2 each contain a CU and multiple DUs. Base stations #1 and #2 can communicate with each other, and they can also communicate with the core network. Specifically, the functions of the radio resource control (RRC) protocol layer, service data adaptation protocol (SDAP) layer, and packet data convergence protocol (PDCP) layer are located in the CU, while the functions of the radio link control (RLC) layer, media access control (MAC) layer, and physical (PHY) layer are located in the DU, which are centrally controlled by the CU. CU and DU can be set up separately or included in the same network element, such as in a BBU. Furthermore, the centralized unit CU can be divided into a control plane (CU-CP) and a user plane (CU-UP).

[0273] In another example, the network device may also be a device that includes a radio unit (RU), or a device that includes a CU, a DU, and a RU. The RU may be included in a radio frequency device or radio frequency unit, such as an RRU, an active antenna unit (AAU), or a remote radio head (RRH).

[0274] It is understood that CU (or CU-CP and CU-UP), DU, or RU may have different names in different systems, but those skilled in the art will understand their meaning. For example, in an open radio access network (O-RAN) system, CU can also be called O-CU (open CU), DU can also be called O-DU, CU-CP can also be called O-CU-CP, CU-UP can also be called O-CU-UP, and RU can also be called O-RU. For ease of description, this application uses CU, CU-CP, CU-UP, DU, and RU as examples. Any of the units among CU (or CU-CP, CU-UP), DU, and RU in this application can be implemented through software modules, hardware modules, or a combination of software modules and hardware modules.

[0275] In combination with the two embodiments described above, optionally, the communication system shown in Figure 2 may further include an AI network element; the AI ​​network element is a module with machine learning computing capabilities. In this application, the AI ​​network element can be used to predict the measurement results of the target neighboring cell (i.e., perform inter-frequency prediction). The AI ​​network element can be located in operations and maintenance (OAM), or in network equipment (such as a base station) or CU, or in some terminal equipment, or it can be referred to as a separate network element entity.

[0276] Specifically, in wireless communication systems, the main function of AI network elements is to perform a series of AI calculations based on input data (such as network operation data provided by the RAN or monitored by OAM, including network load and channel quality), including model building, model training, training approximation, and reinforcement learning. The trained models provided by AI network elements have predictive capabilities for changes in the RAN-side network and can typically be used for load prediction and UE path prediction. Furthermore, AI network elements can also use the predicted RAN network performance results from the trained models to perform policy reasoning from the perspectives of network energy saving and mobility optimization, in order to obtain reasonable and efficient energy-saving strategies and mobility optimization strategies.

[0277] When the AI ​​network element is located in the OAM, its communication with the RAN-side gNB can reuse the current northbound interface. When the AI ​​network element is located in the gNB or CU, it can reuse the current F1, Xn, Uu, and other interfaces. When the AI ​​network element becomes an independent network entity, a new communication link needs to be established with the OAM and RAN sides, for example, based on a wired link or a wireless link. When the CP and UP of the CU are separated, the CP is usually responsible for receiving the AI ​​model and subsequent AI inference and policy generation functions. When the CU-CP is further divided into CU-CP1 and CU-CP2, CU-CP1 is usually responsible for receiving the model and subsequent AI inference functions and generating specific interaction signaling, which is then sent by CU-CP2.

[0278] Referring to Figure 4, a schematic diagram of a communication architecture provided in an embodiment of this application is shown. The communication system includes a RAN intelligent controller (RIC). This RIC includes a near-real-time RIC (near-RT RIC) and a non-real-time RIC (non-RT RIC). The near-real-time RIC is used for model training and inference. For example, it is used to train an artificial intelligence (AI) model and then use that AI model for inference. The near-real-time RIC can obtain network-side and / or terminal-side information from network devices (e.g., CU, CU-CP, CU-UP, DU, and / or RU) and / or terminal devices. This information can be used as training data or inference data.

[0279] Optionally, the near real-time RIC can deliver inference results to network devices and / or terminal devices. Optionally, inference results can be exchanged between the CU and DU, and / or between the DU and RU. For example, the near real-time RIC delivers inference results to the DU, and the DU sends them to the RU. This is used to achieve near real-time intelligent management of the RAN. Through data collection and related operations on the E2 interface, near real-time control and optimization of O-RAN modules and resources are achieved.

[0280] For example, a non-real-time RIC is used for model training and inference. For instance, it can be used to train an AI model and then use that model for inference. The non-real-time RIC can obtain network-side and / or terminal-side information from RAN nodes (e.g., CU, CU-CP, CU-UP, DU, and / or RU) and / or terminal devices. This information can be used as training data or inference data, and the inference results can be delivered to the network devices and / or terminal devices. Optionally, inference results can be exchanged between CUs and DUs, and / or between DUs and RUs; for example, the non-real-time RIC delivers the inference results to the DU, which then forwards them to the RU.

[0281] For example, near real-time RIC and non-real-time RIC can also be set up as separate network elements.

[0282] Optionally, near real-time RICs and non-real-time RICs can also be part of other devices. For example, near real-time RICs can be set in network devices (e.g., CU, DU), while non-real-time RICs can be set in OAM, cloud servers, CN, or other network devices.

[0283] In this embodiment, the apparatus for implementing the functions of a network device can be a network device itself; it can also be an apparatus capable of supporting the network device in implementing those functions, such as a chip system, hardware circuit, software module, or a hardware circuit plus a software module. This apparatus can be installed in the network device or used in conjunction with the network device. In this embodiment, the example of a network device being used to implement the functions of a network device is provided only and does not constitute a limitation on the solutions described in this embodiment.

[0284] Network devices and / or terminal devices can be deployed on land, including indoors or outdoors, handheld or vehicle-mounted; they can also be deployed on water; and they can also be deployed in the air on airplanes, balloons, and satellites. This application does not limit the scenario in which the network devices and terminal devices are located. Furthermore, terminal devices and network devices can be hardware devices, or software functions running on dedicated hardware or general-purpose hardware, such as virtualization functions instantiated on a platform (e.g., a cloud platform), or entities that include dedicated or general-purpose hardware devices and software functions. This application does not limit the specific form of the terminal devices and network devices.

[0285] Optionally, the AI ​​network element can be deployed in one or more of the following locations within the communication system: network devices, terminal devices, or core network devices, etc. Alternatively, the AI ​​network element can be deployed independently, for example, in a location other than any of the aforementioned devices, such as in the host or cloud server of an over-the-top (OTT) system. The AI ​​network element can communicate with other devices in the communication system, which can be one or more of the following: network devices, terminal devices, or core network elements, etc.

[0286] It is understood that this application does not limit the number of AI network elements. For example, when there are multiple AI network elements, these elements can be divided based on function, such as different AI network elements being responsible for different functions.

[0287] It can also be understood that AI network elements can be independent devices, or they can be integrated into the same device to achieve different functions. Alternatively, they can be network components in hardware devices, software functions running on dedicated hardware, or virtualization functions instantiated on a platform (e.g., a cloud platform). This application does not limit the specific form of the aforementioned AI network elements.

[0288] In this embodiment of the application, the AI ​​network element can be referred to as an AI node or an AI module.

[0289] Optionally, the measurement method provided in this application embodiment can be implemented by the aforementioned terminal device or network device, or by components of the terminal device or network device, such as by application-specific integrated circuits (ASICs), field-programmable gate arrays (FPGAs), or software (such as program code in memory) deployed in the terminal device or network device components, without limitation.

[0290] In specific implementation, as shown in Figure 2, each terminal device and network device can adopt the composition structure shown in Figure 5, or include the components shown in Figure 5. Figure 5 is a schematic diagram of the structure of a communication device 500 provided in an embodiment of this application. The communication device 500 can be a terminal device or a chip or system-on-a-chip in a terminal device; it can also be a network device or a chip or system-on-a-chip in a network device. As shown in Figure 5, the communication device 500 includes a processor 501, a transceiver 502, and a communication line 503.

[0291] Furthermore, the communication device 500 may also include a memory 504. The processor 501, memory 504, and transceiver 502 can be connected via a communication line 503.

[0292] Wherein, processor 501 may be a central processing unit (CPU), a general-purpose network processor (NP), a digital signal processor (DSP), a programmable logic device (PLD), a microprocessor unit (MPU), a microcontroller unit (MCU), a graphics processing unit (GPU), a field-programmable gate array (FPGA), an artificial intelligence processor (AI processor), or a neural processing unit (NPU), or any combination thereof. Processor 501 may also be other devices with processing functions, such as circuits, devices, or software modules, without limitation.

[0293] Transceiver 502 is used to communicate with other communication devices or other communication networks. These other communication networks can be Ethernet, radio access network (RAN), wireless local area network (WLAN), etc. Transceiver 502 can be a communication module, interface circuit, input / output interface, chip pins, a transceiver, or any device capable of enabling communication.

[0294] Communication line 503 is used to transmit information between the components included in communication device 500.

[0295] Memory 504 is used to store instructions. These instructions can be computer programs.

[0296] The memory 504 can be a read-only memory (ROM) or other type of static storage device that can store static information and / or instructions; it can also be a random access memory (RAM) or other type of dynamic storage device that can store information and / or instructions; it can also be an electrically erasable programmable read-only memory (EEPROM), a compact disc read-only memory (CD-ROM) or other optical disc storage, optical disc storage (including compressed optical discs, laser discs, optical discs, digital universal optical discs, Blu-ray discs, etc.), magnetic disk storage media or other magnetic storage devices, etc., without limitation.

[0297] It is understood that the memory 504 can exist independently of the processor 501 or can be integrated with the processor 501. The memory 504 can be used to store instructions, program code, or some data, etc. The memory 504 can be located inside or outside the communication device 500, without limitation. The processor 501 is used to execute the instructions stored in the memory 504 to implement the measurement method provided in the following embodiments of this application.

[0298] In one example, processor 501 may include one or more CPUs, such as CPU0 and CPU1 in Figure 5.

[0299] As an optional implementation, the communication device 500 may include multiple processors, for example, in addition to the processor 501 in FIG. 5, it may also include a processor 507.

[0300] As an optional implementation, the communication device 500 also includes an output device 505 and an input device 506. For example, the input device 506 is a device such as a keyboard, mouse, microphone, or joystick, and the output device 505 is a device such as a display screen or speaker.

Furthermore, the composition shown in Figure 5 does not constitute a limitation on the communication device. In addition to the components shown in Figure 5, the communication device may include more or fewer components than shown, or combine certain components, or have different component arrangements.

[0302] In this embodiment of the application, the chip system may be composed of chips or may include chips and other discrete devices.

[0303] Furthermore, the actions, terms, etc., involved in the various embodiments of this application can be referenced interchangeably without limitation. The message names or parameter names in the messages between the various devices in the embodiments of this application are merely examples, and other names may be used in specific implementations without limitation.

[0304] The measurement method provided in the embodiments of this application will be described below with reference to the communication system shown in Figure 2. For example, the measurement method described in this application may have different implementation processes in different scenarios; specifically, the measurement method provided in the embodiments of this application will be introduced below using two scenarios as examples.

[0305] Scenario 1: The measurement method described in this application is implemented through the interaction between the terminal device and the network device.

[0306] For example, in this scenario, the terminal device can measure the signal quality of the target neighboring cell and the serving cell, obtaining the measurement results of the target neighboring cell and the serving cell. This allows the terminal device or network device to determine a first channel correlation based on the measurement results of the target neighboring cell and the serving cell. This provides a fundamental basis for determining whether to initiate inter-frequency measurement based on the first channel correlation.

[0307] The target neighboring cell and the serving cell operate on different frequencies. The network device refers to the network device belonging to the serving cell. The first channel correlation is the correlation between the first channel and the second channel corresponding to the first measurement result. The first channel is the radio channel between the terminal device and the serving cell, and the second channel is the radio channel between the terminal device and the target neighboring cell.

[0308] For example, if the target neighboring cell has a different frequency from the serving cell of the terminal device, it can also be understood as the target neighboring cell being a different frequency neighboring cell of the terminal device.

[0309] For example, since the channel state is constantly changing, that is, the correlation between the first channel and the second channel at different times is also different; therefore, the correlation between the first channel and the second channel corresponding to the first measurement result can also be understood as: the correlation between the first channel and the second channel during the measurement period of the first measurement result; or, it can also be understood as: the correlation between the first channel and the second channel during the measurement period based on the first configuration information.

[0310] For example, in one scenario, the measurement method provided in this application embodiment has the following two possible implementations:

[0311] In one possible implementation, the first channel correlation is determined by the network device (i.e., the network equipment).

[0312] Referring to Figure 6, which is a flowchart illustrating a measurement method provided in this embodiment of the application under this possible implementation, the method may include the following steps:

[0313] S601. The network device sends the first configuration information to the terminal device, and the terminal device receives the first configuration information from the network device accordingly.

[0314] The first configuration information indicates the measurement time interval or the beam-level measurement result of layer 1. The measurement time interval is the time interval between the measurement time of the serving cell of the terminal device and the measurement time of the target neighbor cell. The beam-level measurement result of layer 1 includes the beam-level sampling result of layer 1 or the beam-level filtering result of layer 1. The beam-level filtering result of layer 1 is obtained by filtering the beam-level sampling result of layer 1 after layer 1.

[0315] For example, the time interval between the measurement time of the serving cell and the measurement time of the target neighboring cell can also be understood as the interval between the time of measuring the serving cell and the time of measuring the target neighboring cell.

[0316] For example, the measurement time interval can be the interval between the start time of the serving cell and the end time of the target neighbor cell, or the measurement time interval can be the interval between the start time of the serving cell and the start time of the target neighbor cell, or the measurement time interval can be the interval between the end time of the serving cell and the start time of the target neighbor cell, or the measurement time interval can be the interval between the end time of the serving cell and the end time of the target neighbor cell.

[0317] It is understood that in this application, the measurement time interval can be a maximum time interval, meaning the time interval between the measurement time of the serving cell and the measurement time of the target neighbor cell can be less than or equal to this measurement time interval. Since the channel state is constantly changing, if the time interval between the measurement time of the serving cell and the measurement time of the target neighbor cell is too large, it may lead to a decrease in the accuracy of channel correlation. Therefore, it is advisable to set a time interval threshold (i.e., the measurement time interval) to avoid affecting the accuracy of channel correlation due to an excessively large measurement time interval.

[0318] For example, typically, measurements are performed by Layer 1, where Layer 1 obtains its beam-level sampling results. Layer 3 then filters these multiple Layer 1 beam-level sampling results to obtain its own beam-level filtered results. Currently, the Layer 3 beam-level filtered results are usually used as the measurement result. However, time averaging is performed during the filtering process, and measurement time is a crucial factor in determining correlation in this application. This can easily affect the accuracy of the correlation determined based on the Layer 3 beam-level filtered results. Therefore, this application considers directly using the Layer 1 beam-level sampling results as the measurement result, or having Layer 1 filter its sampling results to remove noise and other interference. Furthermore, the Layer 1 beam-level filtered results are used as the measurement result, thus avoiding the impact of Layer 3's filtering process on the accuracy of the correlation.

[0319] Optionally, the first configuration information may be carried in any of the following: RRC signaling, media access control-resource element (MAC-CE) signaling, or downlink control information (DCI).

[0320] Optionally, the first configuration information may further indicate the measurement object; wherein the measurement pair includes the target neighboring cell and / or the serving cell. For example, the first configuration information may include the identification (ID) of the target neighboring cell and / or the ID of the serving cell.

[0321] For example, the measurement object includes a target neighboring cell, but it can also be replaced by: the measurement object includes at least one target neighboring cell; for ease of description, this application will use the example of the measurement object including one target neighboring cell, and will not be repeated here.

[0322] It is understandable that the above measurement objects are described at the cell level (i.e., the measurement objects include target neighboring cells and / or serving cells). Considering cell-level measurement requires measuring all beams within the cell; however, beam-level measurement only measures a portion of the beams within the cell, thus reducing measurement complexity and improving efficiency. Therefore, the measurement objects can also be described at the beam level; that is, the measurement objects include one or more beams of the target neighboring cell and / or one or more beams of the serving cell. In other words, the measurement objects include the target neighboring cell, including one or more beams of the target neighboring cell; the measurement objects include the serving cell, including one or more beams of the serving cell. For example, the measurement objects may include the IDs of one or more beams of the target neighboring cell and / or the IDs of one or more beams of the serving cell.

[0323] Optionally, the first configuration information can be determined based on the capability information reported by the terminal device. That is, as shown in Figure 7, before step S601, the measurement method further includes the following step S600:

[0324] S600: The terminal device sends capability information to the network device, and the network device receives the capability information from the terminal device. The capability information indicates that the terminal device supports reporting layer 1 beam-level measurement results.

[0325] Optionally, the capability information can be reported proactively by the terminal device, or it can be reported by the terminal device at the instruction of the network device.

[0326] For example, taking a network device instructing a terminal device to report capability information, where the terminal device is a UE, the network device can instruct the terminal device to report capability information through the UECapabilityEnquiry information; thus, the terminal device can report its supported Layer 1 beam-level measurement results through the UECapabilityInformation. In other words, the capability information is carried in the user capability information.

[0327] Alternatively, the network device can instruct the terminal device via RRC signaling to report UE assistance information (UAI); thus, the terminal device can report its supported Layer 1 beam-level measurement results via UAI. In other words, capability information is carried within the UAI. Alternatively, the terminal device can also report capability information in any other possible form; this application does not impose any restrictions.

[0328] Optionally, the capability information also indicates that the terminal device supports reporting layer 3 beam-level filtering results.

[0329] Optionally, the capability information also indicates the relationship between the prediction accuracy and correlation of the first model, wherein the first model is located within the terminal device and is used to predict the measurement results of the target neighboring area.

[0330] For example, the terminal device can also report the accuracy that the first model can achieve when performing predictions under different correlations. For instance, the capability information can indicate that when the correlation is in the range of [a, b], the RSRP error (e.g., root mean square error, RMSE) of the target neighboring region predicted by the first model is in the range of [c, e] decibels (dB). Here, a and b are both greater than 0 and less than 1, and a is greater than b; c and e are both greater than 0, and c is greater than e.

[0331] Specifically, the execution / prediction of the first model can also be understood as: the terminal device uses the first model to predict the measurement results of the target neighboring area; or, it can also be understood as: the terminal device starts the first model, so that the first model performs the function of predicting the measurement results of the target neighboring area.

[0332] S602. The terminal device determines the first measurement result based on the first configuration information. The first measurement result includes the measurement result of the target neighboring cell.

[0333] For example, when the first configuration information indicates a measurement time interval, the terminal device, when measuring the signal quality of the target neighboring cell, may consider making the interval between the time for measuring the signal quality of the target neighboring cell and the time for measuring the signal quality of the serving cell less than or equal to the measurement time interval. When the first configuration information indicates a layer 1 beam-level sampling result, the terminal device, when measuring the signal quality of the target neighboring cell, performs layer 1 filtering processing on the layer 1 beam-level sampling result obtained from measuring the signal quality of the target neighboring cell to remove noise and other interference, obtaining a layer 1 beam-level filtered result, and using it as the measurement result of the target neighboring cell.

[0334] Optionally, since the target neighboring cell is a different frequency neighboring cell of the terminal device, the terminal device needs to measure the signal quality of the target neighboring cell within the pre-configured measurement GAP; that is, before step S602, the network device also needs to configure the measurement GAP for the terminal device. For example, the configuration information of the measurement GAP and the first configuration information can be located in the same signaling, or they can be located in different signaling; this application does not impose any restrictions.

[0335] Optionally, the first measurement result may also include the measurement result of the serving cell. Specifically, when the first configuration information indicates a measurement time interval, the terminal device, when measuring the signal quality of the serving cell, may consider making the interval between the time for measuring the signal quality of the target neighboring cell and the time for measuring the signal quality of the serving cell less than or equal to the measurement time interval. When the first configuration information indicates a layer 1 beam-level sampling result, the terminal device, after obtaining the layer 1 beam-level sampling result by measuring the signal quality of the serving cell, directly uses it as the measurement result of the serving cell. When the first configuration information indicates a layer 1 beam-level filtering result, the terminal device, when measuring the signal quality of the serving cell, may use the layer 1 beam-level filtering result obtained by measuring the signal quality of the serving cell as the measurement result of the serving cell.

[0336] Optionally, when the first configuration information also indicates a measurement object, the terminal device can measure the signal quality of the measurement object to obtain a first measurement result. For example, when the measurement object includes a target neighboring cell, the first measurement result includes the measurement result of the target neighboring cell. When the measurement object includes a serving cell, the first measurement result includes the measurement result of the serving cell. When the measurement object includes one or more beams of the target neighboring cell, the first measurement result includes the measurement result of one or more beams of the target neighboring cell; in this case, it can also be considered that the measurement result of the target neighboring cell includes the measurement result of one or more beams of the target neighboring cell. When the measurement object includes one or more beams of the serving cell, the first measurement result includes the measurement result of one or more beams of the serving cell; in this case, it can also be considered that the measurement result of the serving cell includes the measurement result of one or more beams of the serving cell.

[0337] S603, The terminal device sends the first measurement result to the network device; correspondingly, the network device receives the measurement result from the terminal device.

[0338] For example, the first measurement result may be carried in any one of RRC signaling, MAC-CE signaling, uplink control information (UCI), physical uplink control channel (PUCCH), or physical uplink shared channel (PUSCH).

[0339] S604. The network device determines the first channel correlation based on the first measurement result.

[0340] For example, when the first measurement result includes the measurement result of the serving cell and the measurement result of the target neighboring cell, the network device can determine the first channel correlation based on the first measurement result. For instance, the network device can calculate the Pearson correlation coefficient (PCC) based on the measurement results of the serving cell and the target neighboring cell to obtain the first channel correlation. Alternatively, the network device can determine the first channel correlation based on any other possible method, which is not limited in this application.

[0341] For example, when the granularity of the measurement object is a cell, the first channel correlation refers to the channel correlation between the serving cell and the target neighboring cell (i.e., the first channel and the second channel). When the granularity of the measurement object is a beam, the first channel correlation includes one or more sub-correlations. If the measurement object includes beam A of the serving cell and beam B of the target neighboring cell, then the first channel correlation includes one sub-correlation. In this case, this sub-correlation is the first channel correlation, i.e., the correlation between beam A and beam B.

[0342] For example, when the first measurement result does not include the measurement result of the serving cell, the network device also needs to obtain the measurement result of the serving cell, such as instructing the terminal device to measure and report the measurement result of the serving cell before step S604, so that the network device can determine the first channel correlation based on the measurement result of the serving cell and the measurement result of the target neighboring cell.

[0343] Based on the aforementioned knowledge, the higher the channel correlation, the higher the accuracy of inter-frequency prediction. Therefore, after determining the first channel correlation, the network device can determine whether to start inter-frequency prediction (i.e., use the first model to predict the measurement results of the target neighboring cell) based on the first channel correlation.

[0344] Understandably, for terminal devices located within the overlapping area of ​​the signal coverage of the target neighboring cell and the serving cell, or in other words, for terminal devices located within the overlapping area of ​​a beam range of the target neighboring cell and a beam range of the serving cell, the channel correlation determined based on the measurement results obtained by the terminal device (such as the measurement results of the target neighboring cell and the measurement results of the serving cell) is generally high. Therefore, the location of the terminal device can be used to determine whether to enable inter-frequency prediction. That is, for a single terminal device, if it is not located within the aforementioned overlapping area, it indicates that the channel correlation (such as the first channel correlation) based on the measurement results obtained by the terminal device (such as the measurement results of the target neighboring cell and the measurement results of the serving cell) is low, and in this case, inter-frequency prediction can be considered not to be enabled. If it is located within the aforementioned overlapping area, it indicates that the channel correlation (such as the first channel correlation) based on the measurement results obtained by the terminal device (such as the measurement results of the target neighboring cell and the measurement results of the serving cell) is high, and in this case, inter-frequency prediction can be considered to be enabled.

[0345] For ease of description, the following example illustrates the process of "network devices determining whether terminal devices should activate the first model based on the first channel correlation." For instance, as shown in Figure 8, after step S604, the measurement method may further include the following steps:

[0346] S605. The network device sends a first indication message to the terminal device, and the terminal device receives the first indication message from the network device. The first indication message indicates whether to start the first model, or in other words, whether to start inter-frequency prediction.

[0347] For example, the first indication information may include 1 bit; when the value of the 1 bit is 1, it indicates that the first indication information indicates to start the first model; correspondingly, when the value of the 1 bit is 0, it indicates that the first indication information indicates not to start (or to shut down) the first model. Alternatively, when the value of the 1 bit is 0, it indicates that the first indication information indicates to start the first model; correspondingly, when the value of the 1 bit is 1, it indicates that the first indication information indicates not to start (or to shut down) the first model.

[0348] Optionally, the network device may determine the first indication information based on the first channel correlation. For example, when the first channel correlation is greater than a first threshold, the first indication information indicates that the first model is started; when the first channel correlation is less than or equal to the first threshold, the first indication information indicates that the first model is turned off or not started.

[0349] Specifically, the first threshold can be pre-agreed upon by the terminal device or the network device; for example, it can be predefined through a protocol; or it can be determined by the terminal device and communicated to the network device; or it can be determined by the network device and communicated to the terminal device.

[0350] Optionally, after activating the first model (or, in other words, activating inter-frequency prediction, i.e., the first indication information indicates the activation of the first model), the network device can continuously monitor the correlation between the first channel and the second channel (e.g., determine the correlation of the second channel); thereby determining whether to disable the first model. As shown in Figure 8, this measurement method may further include the following steps:

[0351] S606. The network device determines the second indication information based on the second channel correlation.

[0352] S607. The network device sends a second instruction message to the terminal device, and the terminal device receives the second instruction message from the network device accordingly.

[0353] The second indication information indicates whether the first model is turned off; the second channel correlation is the correlation between the first channel and the second channel corresponding to the second measurement result; the measurement time of the second measurement result is after the first model is started; and the second measurement result includes the measurement results of the target neighboring cell.

[0354] For example, since the measurement time of the second measurement result is after the first model is started, the correlation between the first channel and the second channel corresponding to the second measurement result can also be understood as: the correlation between the first channel and the second channel during the measurement period of the second measurement result; or, it can also be understood as: the correlation between the first channel and the second channel after the first model is started. In other words, the measurement times of the target neighboring cells included in the first and second measurement results are different. That is, the measurement results of the target neighboring cells included in the first measurement result and the measurement results of the target neighboring cells included in the second measurement result are obtained separately by the terminal device at different times by measuring the channel quality of the target neighboring cells.

[0355] Optionally, the second measurement result also includes the measurement result of the serving cell. In this case, the measurement times of the serving cell measurement results included in the first and second measurement results are different. That is, the serving cell measurement results included in the first and second measurement results are obtained separately by the terminal device at different times by measuring the channel quality of the serving cell.

[0356] Optionally, when the second channel correlation is greater than the first threshold, it indicates that the terminal device can still perform predictions based on the first model, and the second indication information can instruct that the first model not be turned off. When the second channel correlation is less than or equal to the first threshold, it indicates that the terminal device is no longer suitable for prediction using the first model, and the second indication information can instruct that the first model be turned off, i.e., the terminal device exits inter-frequency prediction. Furthermore, after the second indication information instructs that the first model be turned off, the network device can configure a new measurement gap for the terminal device for measuring the signal quality of the target neighboring cell.

[0357] In some embodiments, the second channel correlation is calculated and determined by the network device.

[0358] For example, in this embodiment, the network device continuously monitors the correlation between the first channel and the second channel. This can also be understood as: the network device configures a monitoring gap (GAP) for the terminal device, enabling the terminal device to measure the signal quality of the target neighboring cell within the monitoring GAP, i.e., obtaining and reporting the measurement results of the target neighboring cell included in the second measurement result. This allows the network device to determine the correlation of the second channel based on the second measurement result. That is, before step S606, as shown in FIG9, the measurement method may further include the following steps:

[0359] S608, the network device sends second configuration information to the terminal device; correspondingly, the terminal device receives the second configuration information sent by the network device. The second configuration information indicates the monitoring gap.

[0360] For example, monitoring GAP can be understood as: a measurement GAP used to monitor the correlation between the first channel and the second channel.

[0361] Specifically, the monitoring period for GAP can be different from the measurement period for GAP in step S602 above. For example, consider that the monitoring period for GAP is used to monitor whether the correlation between the first channel and the second channel has changed significantly compared to the correlation between the first channel. Since the channel state usually changes little in a short period of time, a longer monitoring period can be set for GAP so that the correlation between the second channel and the first channel can be significantly different. This allows the network device to re-determine whether to continue starting the first model based on the correlation between the second channel and the first model. Furthermore, when it is determined that the correlation between the second channel is low, the first model can be shut down in a timely manner to avoid affecting the performance of cell handover due to the reduced accuracy of prediction.

[0362] Based on the above introduction to the relationship between monitoring gaps and measurement gaps, it can be seen that a monitoring gap is actually a new measurement gap with a longer period triggered by the terminal device, at which time the original measurement gap is in an inactive state. Therefore, when the terminal device is in a certain measurement gap, the second configuration information indicating monitoring gap can also be replaced by the second configuration information indicating deactivation of the measurement gap, or the second configuration information can also indicate extending the period of the measurement gap, so that the measurement gap becomes a monitoring gap.

[0363] For example, the second configuration information may be carried in any of the following: RRC signaling, MAC-CE signaling, or DCI.

[0364] S609. The terminal device determines the second measurement result based on the second configuration information.

[0365] For example, the terminal device can measure the signal quality of the target neighboring cell within the monitoring GAP to obtain the measurement results of the target neighboring cell included in the second measurement result. Specifically, the implementation of the second measurement result is similar to the implementation of the first measurement result described above, and can be found in the relevant description of the first measurement result, which will not be repeated here.

[0366] S610, The terminal device sends the second measurement result to the network device; correspondingly, the network device receives the second measurement result sent from the terminal device.

[0367] For example, the implementation of step S610 is similar to that of step S603 above. For details, please refer to the relevant specification of step S603 below, which will not be repeated here.

[0368] S611. The network device determines the second channel correlation based on the second measurement result.

[0369] For example, the implementation of the network device determining the second channel correlation based on the second measurement result is similar to the implementation of "the network device determines the first channel correlation based on the first measurement result" in step S604 above. For details, please refer to the relevant description in step S604, which will not be repeated here.

[0370] In other embodiments, the second channel correlation is calculated and determined by the terminal device and reported to the network device.

[0371] For example, in this embodiment, the network device continuously monitors the correlation between the first channel and the second channel. This can also be understood as: the network device configures a monitoring gap (GAP) for the terminal device, causing the terminal device to measure the signal quality of the target neighboring cell within the monitoring GAP, thus obtaining the measurement results of the target neighboring cell included in the second measurement result. Then, based on the second measurement result, the correlation of the second channel is determined and reported. That is, before step S606, as shown in Figure 10, the measurement method may further include the following steps:

[0372] S612, The network device sends the second configuration information to the terminal device; correspondingly, the terminal device receives the second configuration information sent by the network device.

[0373] For example, the implementation of monitoring GAP can be found in the relevant description in step S608 above, and will not be repeated here.

[0374] Optionally, based on the above description of the relationship between monitoring GAP and measurement GAP, a monitoring GAP is actually a new measurement GAP with a longer period triggered by the terminal device, at which time the original measurement GAP is in a deactivated state. Therefore, when the terminal device is in a certain measurement GAP, the second configuration information indicating monitoring GAP can also be replaced by the second configuration information indicating deactivation of the measurement GAP, or the second configuration information can also indicate extending the period of the measurement GAP, so that the measurement GAP becomes a monitoring GAP.

[0375] Optionally, since the second channel correlation is calculated and determined by the terminal device, the network device can also inform the terminal device of the relevant parameters for calculating the first channel correlation through the second configuration information. This allows the terminal device to measure and calculate the second channel correlation based on the same parameters as the first channel correlation, thereby avoiding the difference between the first and second channel correlations being too large or too small due to the influence of factors other than the channel state. This could easily lead to errors in the judgment of whether inter-frequency prediction is turned off, affecting cell handover performance.

[0376] For example, the second configuration information also indicates the calculation method of the first channel correlation or the second channel correlation, the first indication information determined based on the first channel correlation, the measurement object corresponding to the first measurement result or the second measurement result, or the first accuracy.

[0377] The calculation methods for the first channel correlation and the second channel correlation are the same, the measurement objects corresponding to the first measurement result and the second measurement result are the same, and the first accuracy rate is the prediction accuracy rate of the first model expected by the serving cell.

[0378] For example, specifically, accuracy can be represented by RMSE. For instance, the first accuracy can be 1 dB, meaning that when the RMSE of the first model is less than or equal to 1 dB, it indicates that the prediction accuracy of the first model meets the first accuracy requirement.

[0379] S613. The terminal device determines the second measurement result based on the second configuration information.

[0380] For example, the terminal device can measure the signal quality of the target neighboring cell within the monitoring GAP to obtain the measurement results of the target neighboring cell included in the second measurement result. Specifically, the implementation of the second measurement result is similar to the implementation of the first measurement result described above, and can be found in the relevant description of the first measurement result, which will not be repeated here.

[0381] For example, when the second configuration information indicates a calculation method for the first channel correlation or the second channel correlation, the terminal device can calculate the second channel correlation based on that calculation method. When the first indication information is determined based on the first channel correlation, it means that after the terminal device determines the second channel correlation, it needs to compare it with the first channel correlation to determine whether to turn off the first model. When the measurement object corresponds to the first measurement result or the second measurement result, the terminal device measures the measurement object to obtain the second measurement result and determines the second channel correlation based on the second measurement result.

[0382] When the second configuration information indicates a first accuracy rate, the terminal device can determine whether the prediction accuracy of the first model meets the first accuracy rate. If the prediction accuracy of the first model meets the first accuracy rate, the terminal device can use the first model to predict the measurement results of the target neighboring cell; if the prediction accuracy of the first model does not meet the first accuracy rate, the terminal device can train the first model until the prediction accuracy of the first model meets the first accuracy rate, and then use the first model to predict the measurement results of the target neighboring cell.

[0383] S614. The terminal device determines the second channel correlation based on the second measurement result.

[0384] For example, the implementation of the terminal device determining the second channel correlation based on the second measurement result is similar to the implementation of "the network device determines the first channel correlation based on the first measurement result" in step S604 above. For details, please refer to the relevant description in step S604, which will not be repeated here.

[0385] S615, The terminal device sends a second channel correlation to the network device; correspondingly, the network device receives the second channel correlation sent by the terminal device.

[0386] Optionally, the second channel correlation can be carried in any one of RRC signaling, MAC-CE signaling, UCI, PUCCH, or PUSCH.

[0387] Optionally, the terminal device sends a second channel correlation to the network device, including: the terminal device sending request information to the network device, the request information being used to request the activation or deactivation of the first model. Therefore, step S606 can be replaced by: the network device determining second indication information based on the request information. In this case, the second indication information can be considered as a response to the request information.

[0388] For example, when the first model is enabled, the request message requesting to enable the first model can be replaced with: the request message requesting to continue using the first model for prediction, or in other words, the request message requesting to continue starting inter-frequency prediction. When the first model is disabled, the request message requesting to disable the first model can be replaced with: the request message requesting to continue using the measurement GAP to measure the signal quality of the target neighboring cell, or in other words, the request message requesting not to start inter-frequency prediction.

[0389] It is understood that in both of the above embodiments, the implementation of the second indication information is described using "the first indication information instructing the initiation of the first model" as an example. When the first indication information instructs the initiation of the first model, the terminal device still uses the measurement gap to measure the signal quality of the target neighboring cell. Therefore, when the channel correlation calculated based on the measurement results of the target neighboring cell determined by the measurement gap is greater than the first threshold, the network device can instruct the terminal device to activate the first model. Specifically, the channel correlation can be calculated and determined by the terminal device or the network device. When the channel correlation is calculated and determined by the terminal device, the terminal device can send the channel correlation to itself, or it can request the network device to activate the current measurement gap, or request to extend the period of the current measurement gap, making the measurement gap a monitoring gap. The current measurement gap is the measurement gap the terminal device is currently in. Therefore, after receiving this request, the second device knows that the second correlation is greater than the first threshold, and thus the first model needs to be activated.

[0390] It should be noted that both of the above embodiments are based on the premise that the network device sends the second indication information to the terminal device to describe the implementation of "the network device obtaining the second channel correlation". In fact, when the terminal device can calculate and determine the second channel correlation, the network device may not need to send the second indication information to the terminal device (i.e., the network device does not need to execute steps S606 to S607). After determining the second channel correlation (i.e., the terminal device executes steps S612 to S615), the terminal device can determine whether to close the first model based on the second channel correlation and the first threshold. In this case, the second channel correlation can be carried in any one of RRC signaling, MAC-CE signaling, UCI, PUCCH, or PUSCH. Alternatively, the terminal device sending the second channel correlation to the network device includes: the terminal device sending the third indication information to the network device, the third indication information indicating that the first model has been turned on or off.

[0391] Optionally, the terminal device described in the two possible implementations above can be determined by the network device based on the location of different terminal devices. For example, before step S601, as shown in Figure 11, the measurement method may further include the following steps:

[0392] S616. Network devices acquire location information of multiple terminal devices. These multiple terminal devices include the terminal devices themselves.

[0393] For example, a network device can estimate the location information of multiple terminal devices based on measurements of uplink information (such as uplink reference signals) sent to the network device by multiple terminal devices respectively. Alternatively, the network device can estimate the location information of multiple terminal devices based on downlink information (such as downlink reference signals) sent to multiple terminal devices respectively. Alternatively, multiple terminal devices can report their location information to the network device individually. Alternatively, the network device can obtain the location information of multiple terminal devices through any other possible means.

[0394] S617. The network device determines at least one set based on the location information of multiple terminal devices.

[0395] Each of the at least one set includes one or more terminal devices, and the location spacing between the one or more terminal devices is less than or equal to a second threshold. The terminal devices are included within at least one set.

[0396] Specifically, the second threshold can be pre-agreed upon by the terminal device or the network device; for example, it can be predefined through a protocol; or it can be determined by the terminal device and informed by the network device; or it can be determined by the network device and informed by the terminal device.

[0397] For example, when each set includes multiple terminal devices, these multiple terminal devices include terminal devices located in the overlapping area of ​​the coverage of the serving cell and the target neighboring cell (or the overlapping area of ​​a specific beam of the serving cell and a specific beam of the target neighboring cell), and terminal devices located in non-overlapping areas. In this case, the terminal device is the terminal device located in the overlapping area.

[0398] Furthermore, the network device sends different configuration information to different terminal devices within the same set, enabling each terminal device to determine and report different measurement results. Specifically, for a terminal device located in an overlapping area, the network device can send configuration information #1, instructing it to determine and report the measurement results of the target neighboring cell. For example, for the terminal device, step S601 can be executed, where the first measurement result described in Figures 6-10 is the measurement result of the target neighboring cell. That is, at this time, the terminal device only uses the measurement results of the target neighboring cell and not to determine the measurement results of the serving neighboring cell. For a terminal device located in a non-overlapping area, the network device can send configuration information #2, instructing it to determine and report the measurement results of the serving neighboring cell.

[0399] For example, when determining or issuing configuration information #1 and configuration information #2, the timing of issuance or the timing of reporting the measurement results can be considered so that the terminal device can report the measurement results it has obtained as simultaneously or nearly simultaneously as possible.

[0400] Based on this possible implementation, the terminal device can determine the measurement result (i.e., the first measurement result) of the target neighbor cell to report to the network device based on the first configuration information configured for it by the network device. This allows the network device to use the measurement result of the target neighbor cell to determine the channel correlation (i.e., the first channel correlation, which is the correlation between the first channel and the second channel corresponding to the first measurement result; the first channel is the radio channel between the terminal device and the serving cell, and the second channel is the radio channel between the terminal device and the target neighbor cell). The first configuration information indicates a measurement time interval or a Layer 1 beam-level measurement result. The measurement time interval is the time interval between the measurement time of the terminal device's serving cell and the measurement time of the target neighbor cell. The target neighbor cell and the serving cell have different frequency points. The Layer 1 beam-level measurement result includes a Layer 1 beam-level sampling result or a Layer 1 beam-level filtering result. The Layer 1 beam-level filtering result is obtained by filtering the Layer 1 beam-level sampling result.

[0401] It is understandable that, since the channel state is constantly changing, if the time interval between the measurement time of the serving cell and the measurement time of the target neighboring cell is too large, it may lead to a decrease in the accuracy of channel correlation. Therefore, it is advisable to set a time interval threshold (i.e., measurement time interval) to avoid affecting the accuracy of channel correlation due to an excessively large measurement time interval.

[0402] Furthermore, measurements are typically performed by Layer 1, where Layer 1 obtains its beam-level sampling results. Layer 3 then filters these multiple Layer 1 beam-level sampling results to obtain its own beam-level filtered results. Currently, the Layer 3 beam-level filtered results are usually used as the measurement results. However, the Layer 3 filtering process involves time averaging, and measurement time is a crucial factor in determining correlation in this application. This can easily affect the accuracy of the correlation determined based on the Layer 3 beam-level filtered results. Therefore, this application directly uses the Layer 1 beam-level sampling results as the measurement results, or has Layer 1 filter the sampling results to eliminate interference, obtaining the Layer 1 beam-level filtered results which are then used as the measurement results. This avoids the Layer 3 filtering process affecting the accuracy of the correlation.

[0403] Furthermore, since the higher the channel correlation value, the higher the accuracy of inter-frequency prediction (i.e., predicting the measurement results of the target neighbor cell through the measurement results of the serving cell), it is considered that inter-frequency prediction can be used when the first channel correlation value is large, thereby reducing or lowering the use of measurement gaps and improving the throughput of terminal devices.

[0404] In another possible implementation, the first channel correlation is determined by the terminal device.

[0405] Referring to Figure 12, which is a flowchart illustrating another measurement method provided by an embodiment of this application under this possible implementation, as shown in Figure 12, the method may include the following steps:

[0406] S1201, The network device sends the first configuration information to the terminal device, and the terminal device receives the first configuration information from the network device accordingly.

[0407] The first configuration information indicates one or more of the following: measurement time interval, channel correlation value accuracy, or channel correlation calculation method. The measurement time interval is the time interval between the measurement time of the serving cell of the terminal device and the measurement time of the target neighboring cell.

[0408] For example, the time interval between the measurement time of the serving cell and the measurement time of the target neighboring cell can also be understood as the interval between the time of measuring the serving cell and the time of measuring the target neighboring cell.

[0409] For example, the measurement time interval can be the interval between the start time of the serving cell and the end time of the target neighbor cell, or the measurement time interval can be the interval between the start time of the serving cell and the start time of the target neighbor cell, or the measurement time interval can be the interval between the end time of the serving cell and the start time of the target neighbor cell, or the measurement time interval can be the interval between the end time of the serving cell and the end time of the target neighbor cell.

[0410] For example, the measurement time interval can be a maximum time interval, meaning the time interval between the measurement time of the serving cell and the measurement time of the target neighbor cell can be less than or equal to this measurement time interval. Since the channel state is constantly changing, if the time interval between the measurement time of the serving cell and the measurement time of the target neighbor cell is too large, it may lead to a decrease in the accuracy of channel correlation. Therefore, it is advisable to set a time interval threshold (i.e., the measurement time interval) to avoid affecting the accuracy of channel correlation due to an excessively large measurement time interval.

[0411] Alternatively, the measurement time interval can be a minimum time interval, meaning the time interval between the measurement time of the serving cell and the measurement time of the target neighboring cell can be greater than or equal to this measurement time interval. Since they are usually located within a measurement gap, the terminal device can determine the measurement time of the serving cell based on the measurement time interval, thereby measuring the signal quality of the serving cell.

[0412] For example, the precision of channel correlation values ​​can also be understood as the required resolution of the channel correlation value. Taking a floating-point value as an example, the precision of the channel correlation value can indicate to which decimal point the channel correlation value can be accurate.

[0413] For example, the calculation of channel correlation may include PCC calculation, or the network device may use any other possible calculation method, which is not limited in this application.

[0414] Optionally, the first configuration information further indicates at least one set of measurement objects; wherein, any one of the at least one set of measurement objects includes a first beam and a second beam, the first beam belongs to the serving cell, the second beam belongs to the target neighboring cell, and the first channel correlation includes the correlation between the first beam and the second beam.

[0415] For example, at least one set of measurement objects may include two sets of measurement objects, one set of measurement objects including beam #1 and beam #2, and the other set of measurement objects including beam #3 and beam #4; wherein beam #1 and beam #3 are both first beams, and beam #2 and beam #4 are both second beams; that is, beam #1 and beam #3 are beams under the serving cell; beam #2 and beam #4 are beams under the target neighboring cell.

[0416] It is understood that the above-mentioned at least one set of measurement objects consists of the serving cell and a target neighbor cell downbeam; in fact, at least one set of measurement objects consists of the serving cell and different target neighbor cells downbeams respectively; for the sake of convenience, this application will take the example of at least one set of measurement objects consisting of the serving cell and a target neighbor cell downbeam, and will not be repeated here.

[0417] Optionally, the first configuration information may also indicate the measurement period. The measurement period is the time interval to which the first measurement result corresponds.

[0418] For example, the measurement period is the time period to which the measurement time corresponding to the first measurement result belongs, which can also be understood as: the measurement result of the target neighboring cell is located within this measurement period; further, the measurement result of the serving cell is located within this measurement period. Specifically, the measurement period can be within X seconds / milliseconds from the time the terminal device receives the first configuration information, where X is a positive integer.

[0419] Optionally, the first configuration information can be carried in any of the following: RRC signaling, MAC-CE signaling, or DCI.

[0420] Optionally, the first configuration information can be determined based on the capability information reported by the terminal device. That is, as shown in Figure 12, before step S1201, the measurement method further includes the following step S1200:

[0421] S1200: The terminal device sends capability information to the network device, and the network device receives the capability information from the terminal device. The capability information indicates whether the terminal device supports calculating channel correlation. At this point, step S1201 can be replaced by: the network device determining first configuration information based on the capability information.

[0422] For example, capability information can be represented by 1 bit; when the value of this 1 bit is 1, it indicates that the terminal device supports calculating channel correlation; correspondingly, when the value of this 1 bit is 0, it indicates that the terminal device does not support calculating channel correlation. Alternatively, when the value of this 1 bit is 0, it indicates that the terminal device supports calculating channel correlation; correspondingly, when the value of this 1 bit is 1, it indicates that the terminal device does not support calculating channel correlation.

[0423] Optionally, the capability information can be reported proactively by the terminal device, or it can be reported by the terminal device at the instruction of the network device.

[0424] For example, when the network device instructs the terminal device to report capability information, the network device instructs the terminal device to report capability information, and the implementation of the capability information can be found in the relevant description in step S600 above, and will not be repeated here.

[0425] Optionally, when the capability information indicates that the terminal device supports calculating channel correlation, the capability information may also indicate that the terminal device supports one or more of the following: the type of input information required for calculating channel correlation, a first quantity, a measurement time interval, a threshold for channel correlation, a method for calculating channel correlation, or a measurement period. In other words, the capability information may implicitly indicate that the terminal device supports calculating channel correlation by indicating one or more of the following: the type of input information required for calculating correlation, a first quantity, a measurement time interval, a threshold for channel correlation, a method for calculating channel correlation, or a measurement period.

[0426] The input information required for calculating channel correlation includes any one of the following: Layer 1 beam-level filtering results, Layer 1 beam-level sampling results, or Layer 3 beam-level filtering results. Layer 1 beam-level measurement results include either Layer 1 beam-level sampling results or Layer 1 beam-level filtering results. Layer 1 beam-level filtering results are obtained by filtering Layer 1 beam-level sampling results. The first quantity is the number of measurement object groups. Each measurement object group includes a first beam and a second beam. The first beam belongs to the serving cell, and the second beam belongs to the target neighboring cell. The correlation threshold is the maximum or minimum correlation value. The measurement period is the time period to which the measurement result corresponds to the measurement time.

[0427] For example, since channel correlation is determined based on the measurement results of the serving cell and the target neighboring cell, the input information required to calculate channel correlation can be understood as: the measurement results of the serving cell and the target neighboring cell. Furthermore, the type of input information required to calculate channel correlation can be understood as: whether the measurement results of the serving cell and the target neighboring cell are layer 1 beam-level filtering results, layer 1 beam-level sampling results, or layer 3 beam-level filtering results. Therefore, the terminal device can determine the measurement results of the serving cell and the target neighboring cell based on the type of input information.

[0428] Specifically, the implementation of the beam-level filtering results of layer 1, the beam-level sampling results of layer 1, and the beam-level filtering results of layer 3 can be found in the relevant descriptions in step S601 above, and will not be repeated here.

[0429] Optionally, at least one group of measurement objects may have a number of groups less than or equal to a first quantity. Further, the capability information may indicate which groups of measurement objects constitute the first quantity; that is, the capability information may indicate which groups of measurement objects constitute the first quantity. In this case, the aforementioned at least one group of measurement objects may be some or all of the measurement objects within the first quantity.

[0430] For example, the implementation of each group of measurement objects in the first number of groups of measurement objects is similar to the implementation of any one of the above at least one group of measurement objects. For details, please refer to the relevant description of the above at least one group of measurement objects. However, the first beam included in each group of measurement objects may be the same as or different from the first beam included in any one of the above measurement objects. Similarly, the second beam included in each group of measurement objects may be the same as or different from the second beam included in any one of the above measurement objects.

[0431] For example, the implementation of the measurement time interval indicated by the capability information is similar to that of the measurement time interval indicated by the first configuration information. For details, please refer to the implementation of the measurement time interval in step S1201 above, which will not be repeated here. However, the values ​​of the measurement time interval indicated by the capability information and the measurement time interval indicated by the first configuration information may be the same or different. The measurement time interval indicated by the first configuration information can be determined based on the measurement time interval indicated by the capability information.

[0432] For example, the threshold for channel correlation can be the maximum or minimum value of channel correlation. Taking the maximum value of channel correlation as an example, the threshold for channel correlation can be represented by the maximum number of bits or the highest division value. Therefore, network devices can determine the accuracy of the channel correlation value based on this threshold.

[0433] For example, the implementation of the measurement period indicated by the capability information is similar to that of the measurement period indicated by the first configuration information. For details, please refer to the implementation of the measurement period in step S1201 above, which will not be repeated here. However, the values ​​of the measurement period indicated by the capability information and the measurement period indicated by the first configuration information may be the same or different. The measurement period indicated by the first configuration information can be determined based on the measurement period indicated by the capability information.

[0434] For example, the channel correlation calculation method indicated by the capability information includes, but is not limited to, PCC calculation. Therefore, the network device can determine the channel correlation calculation method indicated by the first configuration information based on the channel correlation calculation method indicated by the capability information.

[0435] Optionally, the capability information also indicates the relationship between the prediction accuracy and correlation of the first model, wherein the first model is located within the terminal device and is used to predict the measurement results of the target neighboring area.

[0436] For example, the capability information also indicates the realization of the relationship between the prediction accuracy and correlation of the first model, as can be seen in the relevant description in step S600 above, and will not be repeated here.

[0437] S1202, The terminal device determines the first measurement result based on the first configuration information. The first measurement result includes the measurement result of the target neighboring cell.

[0438] For example, when the first configuration information indicates a measurement time interval, the terminal device may consider making the interval between the time for measuring the signal quality of the target neighboring cell and the time for measuring the signal quality of the serving cell less than or equal to the measurement time interval when measuring the signal quality of the target neighboring cell.

[0439] Optionally, the terminal device can also determine, based on the type of input information required for calculating channel correlation, whether it is the beam-level filtering result of the first measurement result layer 1, the beam-level sampling result of layer 1, or the beam-level filtering result of layer 3.

[0440] Optionally, when the first configuration information indicates at least one set of measurement objects, the terminal device can measure these measurement objects to obtain a first measurement result.

[0441] Optionally, since the target neighboring cell is a different frequency neighboring cell of the terminal device, the terminal device needs to measure the signal quality of the target neighboring cell within the pre-configured measurement GAP; that is, before step S1202, the network device also needs to configure the measurement GAP for the terminal device. For example, the configuration information of the measurement GAP and the first configuration information can be located in the same signaling, or they can be located in different signaling, which is not limited in this application.

[0442] Optionally, the first measurement result may also include the measurement result of the serving cell. Specifically, when the first configuration information indicates a measurement time interval, the terminal device, when measuring the signal quality of the serving cell, may consider making the interval between the time for measuring the signal quality of the target neighboring cell and the time for measuring the signal quality of the serving cell less than or equal to that measurement time interval.

[0443] S1203. The terminal device determines the first channel correlation based on the first measurement result.

[0444] Optionally, when the first configuration information is determined based on the capability information, step S1203 can also be replaced by: when the terminal device supports calculating correlation, determining the first channel correlation based on the first measurement result.

[0445] For example, when the first measurement result includes the measurement result of the serving cell and the measurement result of the target neighboring cell, the terminal device can determine the first channel correlation based on the first measurement result. When the first measurement result does not include the measurement result of the serving cell, the terminal device also needs to determine the measurement result of the serving cell, and then determine the first channel correlation based on the measurement result of the serving cell and the measurement result of the target neighboring cell.

[0446] For example, the terminal device can calculate the PCC based on the measurement results of the serving cell and the target neighboring cell, thereby obtaining the first channel correlation. Specifically, the calculation method of the first channel correlation is the same as the calculation method of the channel correlation indicated by the first configuration information.

[0447] For example, the first channel correlation includes one or more sub-correlations. Each of these one or more sub-correlations is the correlation of a set of measurements from the at least one set of measurements mentioned above.

[0448] S1204. The terminal device sends the first channel correlation to the network device, and the network device receives the first channel correlation from the terminal device.

[0449] For example, the first channel correlation can be carried in any of the following: RRC signaling, MAC-CE signaling, UCI, PUCCH, or PUSCH.

[0450] Optionally, the network device may store the first channel correlation after receiving it.

[0451] Since higher channel correlation leads to higher inter-frequency prediction accuracy, after determining the first channel correlation, the terminal device or network device can determine whether to initiate inter-frequency prediction (i.e., use the first model to predict the measurement results of the target neighboring cell) based on the first channel correlation.

[0452] (i) When the terminal device determines whether to initiate inter-frequency prediction:

[0453] For example, a network device can determine whether a first model is enabled based on a first channel correlation and a first threshold. For instance, if the first channel correlation is greater than the first threshold, it indicates that the first model is enabled; if the first channel correlation is less than or equal to the first threshold, it indicates that the first model is not enabled. In this case, the terminal device still uses a measurement gap (such as a measurement gap newly configured by the network device for the terminal device) to measure the measurement results of the target neighboring cells.

[0454] Specifically, the implementation of the first threshold can be found in the relevant description of the above embodiments, and will not be repeated here.

[0455] Optionally, when the correlation of the first channel is greater than the first threshold, the terminal device may activate the first model (i.e., activate inter-frequency prediction). For example, as shown in Figure 13, after step S1204, the measurement method may further include the following steps:

[0456] S1205. The terminal device uses the first model to predict the measurement results of the target neighboring cell.

[0457] For example, when the correlation of the first channel is greater than the first threshold, the terminal device can enable inter-frequency prediction, that is, the terminal device uses the first model to predict and obtain the measurement results of the target neighboring cell.

[0458] Optionally, the terminal device can also measure the serving cell's measurement results. Specifically, the measurement objects of the terminal device are the same as those belonging to the serving cell included in the first measurement result mentioned above.

[0459] Optionally, the terminal device can also continuously monitor the correlation between the first channel and the second channel (e.g., determine the correlation of the second channel); thereby determining whether to turn off the first model. For example, as shown in Figure 13, after step S1205, the measurement method may further include the following steps:

[0460] S1206, The network device sends second configuration information to the terminal device; correspondingly, the terminal device receives the second configuration information from the network device. The second configuration information indicates the monitoring of the GAP.

[0461] For example, the implementation of monitoring GAP and the second configuration information can be found in the relevant description in step S608 above, and will not be repeated here.

[0462] S1207. The terminal device determines the second measurement result based on the second configuration information. The measurement time of the second measurement result is after the first model is started, and the second measurement result includes the measurement results of the target neighboring cells.

[0463] For example, the terminal device can measure the signal quality of the target neighboring cell within the monitoring GAP to obtain the measurement results of the target neighboring cell included in the second measurement result. Specifically, the implementation of the second measurement result is similar to the implementation of the first measurement result described above, and can be found in the relevant description of the first measurement result, which will not be repeated here.

[0464] S1208. The terminal device determines the second channel correlation based on the second measurement result.

[0465] For example, the implementation of the terminal device determining the second channel correlation based on the second measurement result is similar to the implementation of "the terminal device determines the first channel correlation based on the first measurement result" in step S1203 above. For details, please refer to the relevant description in step S1203, which will not be repeated here.

[0466] S1209. The terminal device determines whether to turn off the first model based on the second channel correlation.

[0467] For example, the terminal device can determine whether the first model is turned off based on the second channel correlation and the first threshold. For instance, when the second channel correlation is greater than the first threshold, it means that the first model is not turned off, or in other words, the first model remains on; when the second channel correlation is less than or equal to the first threshold, it means that the first model is turned off. Then, the terminal device uses a measurement gap (such as a measurement gap newly configured by the network device for the terminal device) to measure the measurement results of the target neighboring cells.

[0468] Optionally, after step S1209, as shown in Figure 13, the measurement method may further include the following steps:

[0469] S1210, The terminal device sends a second channel correlation to the network device, and the network device receives the second channel correlation from the terminal device accordingly.

[0470] For example, the implementation of step S1210 is similar to that of step S1205 above. For details, please refer to the relevant description of step S1205 above, which will not be repeated here.

[0471] (ii) When the network device determines whether to initiate inter-frequency prediction:

[0472] Typically, for terminal devices located within the overlapping area of ​​the signal coverage of a target neighboring cell and the serving cell, or in other words, for terminal devices located within the overlapping area of ​​a beam range of a target neighboring cell and a beam range of the serving cell, the channel correlation determined based on the measurement results obtained by the terminal device (such as the measurement results of the target neighboring cell and the measurement results of the serving cell) is relatively high. Therefore, the location of the terminal device can be used to determine whether to enable inter-frequency prediction. That is, for a single terminal device, if it is not located within the aforementioned overlapping area, it indicates that the channel correlation (such as the first channel correlation) based on the measurement results obtained by the terminal device (such as the measurement results of the target neighboring cell and the measurement results of the serving cell) is low, and in this case, inter-frequency prediction can be considered not to be enabled. If it is located within the aforementioned overlapping area, it indicates that the channel correlation (such as the first channel correlation) based on the measurement results obtained by the terminal device (such as the measurement results of the target neighboring cell and the measurement results of the serving cell) is high, and in this case, inter-frequency prediction can be considered to be enabled.

[0473] For ease of description, the following example illustrates the process of "network devices determining whether terminal devices should activate the first model based on the first channel correlation." For instance, as shown in Figure 14, after step S1204, the measurement method may further include the following steps:

[0474] S1211, the network device sends a first indication message to the terminal device, and correspondingly, the terminal device receives the first indication message from the network device. The first indication message indicates whether to start the first model, or in other words, whether to start inter-frequency prediction.

[0475] For example, the implementation of the first instruction information can be found in the relevant description in step S605 above, and will not be repeated here.

[0476] Optionally, the network device may determine the first indication information based on the first channel correlation. For example, when the first channel correlation is greater than a first threshold, the first indication information indicates that the first model is started; when the first channel correlation is less than or equal to the first threshold, the first indication information indicates that the first model is turned off or not started.

[0477] Optionally, after activating the first model (or, in other words, activating inter-frequency prediction, i.e., the first indication information indicates the activation of the first model), the network device can continuously monitor the correlation between the first channel and the second channel (e.g., determine the correlation of the second channel); thereby determining whether to disable the first model. As shown in Figure 14, this measurement method may further include the following steps:

[0478] S1212 The network device determines the second indication information based on the second channel correlation.

[0479] S1213. The network device sends a second instruction message to the terminal device, and the terminal device receives the second instruction message from the network device accordingly.

[0480] The second indication information indicates whether the first model is turned off; the second channel correlation is the correlation between the first channel and the second channel corresponding to the second measurement result; the measurement time of the second measurement result is after the first model is started; and the second measurement result includes the measurement results of the target neighboring cell.

[0481] For example, the implementation of the second measurement result can be found in the relevant description in step S607 above, and will not be repeated here.

[0482] Optionally, when the second channel correlation is greater than the first threshold, it indicates that the terminal device can still perform predictions based on the first model, and the second indication information can instruct that the first model not be turned off. When the second channel correlation is less than or equal to the first threshold, it indicates that the terminal device is no longer suitable for prediction using the first model, and the second indication information can instruct that the first model be turned off, i.e., the terminal device exits inter-frequency prediction. Furthermore, after the second indication information instructs that the first model be turned off, the network device can configure a new measurement gap for the terminal device for measuring the signal quality of the target neighboring cell.

[0483] In some embodiments, the second channel correlation is calculated and determined by the network device.

[0484] For example, in this embodiment, the network device continuously monitors the correlation between the first channel and the second channel. This can also be understood as: the network device configures a monitoring gap (GAP) for the terminal device, enabling the terminal device to measure the signal quality of the target neighboring cell within the monitoring GAP, i.e., obtaining and reporting the measurement results of the target neighboring cell included in the second measurement result. This allows the network device to determine the correlation of the second channel based on the second measurement result. That is, before step S1212, as shown in FIG15, the measurement method may further include the following steps:

[0485] S1214. The network device sends second configuration information to the terminal device; correspondingly, the terminal device receives the second configuration information sent by the network device. The second configuration information indicates the monitoring GAP.

[0486] For example, the implementation of step S1214 is the same as that of step S1206 above. For details, please refer to the relevant description of step S1206 above, which will not be repeated here.

[0487] S1215. The terminal device determines the second measurement result based on the second configuration information.

[0488] For example, the implementation of step S1115 is the same as that of step S609 above. For details, please refer to the relevant description of step S609 above, which will not be repeated here.

[0489] S1216. The terminal device sends the second measurement result to the network device; correspondingly, the network device receives the second measurement result sent from the terminal device.

[0490] For example, the implementation of step S1216 is the same as that of step S610 above. For details, please refer to the relevant specification of step S610 below, which will not be repeated here.

[0491] S1217. The network device determines the second channel correlation based on the second measurement result.

[0492] For example, the implementation of step S1217 is the same as that of step S611 above. For details, please refer to the relevant specification of step S611 below, which will not be repeated here.

[0493] Optionally, in step S1217, the network device and the terminal device can also align the relevant parameters for calculating the first channel correlation, so that the network device can measure and calculate the second channel correlation based on the same parameters as the first channel correlation, thereby avoiding the difference between the first channel correlation and the second channel correlation being too large or too small due to the influence of factors other than the channel state, which may easily lead to errors in the judgment of whether inter-frequency prediction is turned off, affecting cell handover performance.

[0494] For example, the relevant parameters for calculating the first channel correlation include, but are not limited to: the calculation method of the first channel correlation or the second channel correlation, the first indication information determined based on the first channel correlation, the measurement object corresponding to the first measurement result or the second measurement result, or the first accuracy.

[0495] The calculation methods for the first channel correlation and the second channel correlation are the same, the measurement objects corresponding to the first measurement result and the second measurement result are the same, and the first accuracy rate is the prediction accuracy rate of the first model expected by the serving cell.

[0496] For example, specifically, accuracy can be represented by RMSE. For instance, the first accuracy can be 1 dB, meaning that when the RMSE of the first model is less than or equal to 1 dB, it indicates that the prediction accuracy of the first model meets the first accuracy requirement.

[0497] In other embodiments, the second channel correlation is calculated and determined by the terminal device and reported to the network device.

[0498] For example, in this embodiment, the network device continuously monitors the correlation between the first channel and the second channel. This can also be understood as: the network device configures a monitoring gap (GAP) for the terminal device, causing the terminal device to measure the signal quality of the target neighboring cell within the monitoring GAP, thus obtaining the measurement results of the target neighboring cell included in the second measurement result. Then, based on the second measurement result, the correlation of the second channel is determined and reported. That is, before step S1212, as shown in Figure 16, the measurement method may further include the following steps:

[0499] S1218. The network device sends the second configuration information to the terminal device; correspondingly, the terminal device receives the second configuration information sent by the network device.

[0500] For example, the implementation of monitoring GAP can be found in the relevant description in step S1214 above, and will not be repeated here.

[0501] S1219. The terminal device determines the second measurement result based on the second configuration information.

[0502] For example, the implementation of step S1219 is the same as that of step S613 above. For details, please refer to the relevant description of step S613 above, which will not be repeated here.

[0503] S1220, The terminal device determines the second channel correlation based on the second measurement result.

[0504] For example, the implementation of step S1220 is the same as that of step S614 above. For details, please refer to the relevant description of step S614 above, which will not be repeated here.

[0505] S1221, The terminal device sends a second channel correlation to the network device; correspondingly, the network device receives the second channel correlation sent by the terminal device.

[0506] Optionally, the second channel correlation can be carried in any one of RRC signaling, MAC-CE signaling, UCI, PUCCH, or PUSCH.

[0507] Optionally, the terminal device sends a second channel correlation to the network device, including: the terminal device sending request information to the network device, the request information being used to request the activation or deactivation of the first model. Therefore, step S606 can be replaced by: the network device determining second indication information based on the request information. In this case, the second indication information can be considered as a response to the request information.

[0508] For example, when the first model is enabled, the request message requesting to enable the first model can be replaced with: the request message requesting to continue using the first model for prediction, or in other words, the request message requesting to continue starting inter-frequency prediction. When the first model is disabled, the request message requesting to disable the first model can be replaced with: the request message requesting to continue using the measurement GAP to measure the signal quality of the target neighboring cell, or in other words, the request message requesting not to start inter-frequency prediction.

[0509] Based on this possible implementation, the terminal device can determine the measurement result (i.e., the first measurement result) of the target neighboring cell based on the first configuration information configured for it by the network device. Furthermore, it can also use the measurement result of the target neighboring cell to determine the channel correlation (i.e., the first channel correlation, which is the correlation between the first channel and the second channel corresponding to the first measurement result; the first channel is the radio channel between the terminal device and the serving cell, and the second channel is the radio channel between the terminal device and the target neighboring cell). The first configuration information indicates one or more of the following: the measurement time interval, the accuracy of the channel correlation value, or the calculation method of the channel correlation. The measurement time interval is the time interval between the measurement time of the serving cell of the terminal device and the measurement time of the target neighboring cell, and the target neighboring cell and the serving cell have different frequency points.

[0510] Understandably, since channel states are constantly changing, a large time interval between the measurement time of the serving cell and the measurement time of the target neighboring cell may reduce the accuracy of channel correlation. Therefore, setting a time interval threshold (i.e., the measurement time interval) can be considered to avoid affecting the accuracy of channel correlation due to an excessively large measurement time interval. And / or, network devices can also configure the precision of channel correlation values ​​for terminal devices, i.e., to what decimal place the channel correlation value can be accurate. For example, network devices can consider setting a higher precision for the channel correlation value to improve the accuracy of the first channel correlation calculated by the terminal device. And / or, network devices can consider configuring the terminal device with the channel correlation calculation methods it supports, avoiding configuring calculation methods that the terminal device does not support, which would prevent the terminal device from calculating the first channel correlation.

[0511] Furthermore, since the higher the channel correlation value, the higher the accuracy of inter-frequency prediction (i.e., predicting the measurement results of the target neighbor cell through the measurement results of the serving cell), it is considered that inter-frequency prediction can be used when the first channel correlation value is large, thereby reducing or decreasing the use of measurement gaps and improving the throughput of terminal devices.

[0512] Scenario 2: Interaction between network devices to implement the measurement method described in this application. Specifically, the interaction between the first network element device and the second network device implements the measurement method described in this application. The cells under the first network device and the cells under the second network device have different frequency points.

[0513] For example, the cells under the first network device and the cells under the second network device have different frequencies. This can also be understood as: any cell in the first network device has a different frequency than any cell in the second network device; that is, any cell in the first network device and any cell in the second network device are inter-frequency neighboring cells.

[0514] For terminal devices located in the overlapping areas of the signal coverage of the first network device or the second network device, the terminal device needs to determine whether to perform cell handover based on the signal quality of its serving cell and the signal quality of neighboring cells. Specifically, the signal quality of neighboring cells can be determined based on inter-frequency prediction. That is, the first channel correlation is first determined based on the signal quality of the serving cell and the signal quality of neighboring cells. This provides a basic guarantee for determining whether to initiate inter-frequency measurement based on the first channel correlation.

[0515] The first channel correlation is the correlation between the first channel and the second channel corresponding to the first measurement result. The first channel is the radio channel between the terminal device and the serving cell, and the second channel is the radio channel between the terminal device and the neighboring cell.

[0516] For example, since the channel state is constantly changing, that is, the correlation between the first channel and the second channel at different times is also different; therefore, the correlation between the first channel and the second channel corresponding to the first measurement result can also be understood as: the correlation between the first channel and the second channel during the measurement period of the first measurement result; or, it can also be understood as: the correlation between the first channel and the second channel during the measurement period based on the first configuration information.

[0517] For example, in scenario two, the terminal device is a terminal device under the second network device; that is, the serving cell of the terminal device is located under the second network device. In other words, the second network device is the network device to which the serving cell belongs. The neighboring cells of the terminal device are located under the first network device. That is, the first network device is the network device to which the neighboring cells belong.

[0518] For example, taking the measurement process initiated by the first network device as an example, the measurement method provided in this application embodiment may include the following two possible implementations:

[0519] In one possible implementation, the first network device requests the measurement results from the terminal device from the second network device, and then determines the first channel correlation based on the measurement results.

[0520] For example, in this possible implementation, as shown in Figure 17, the measurement method may include the following steps:

[0521] S1701, The first network device sends a first request message to the second network device; correspondingly, the second network device receives the first request message from the first network device.

[0522] The first request information indicates one or more of the following: the measurement result acquisition period, the measurement period, and the number of samples of the measurement result. The first request message is used to request the first measurement result. The first measurement result includes the measurement result of the terminal device. The measurement result of the terminal device includes the measurement result of the serving cell and / or the neighboring cell of the terminal device.

[0523] For example, the measurement result acquisition period refers to the implementation of the second network device acquiring the measurement results of the terminal device; for example, it may be the time when the second network device receives the measurement results from the terminal device.

[0524] For example, the measurement period refers to the time interval in which the measurement result of the terminal device is measured. Specifically, the measurement period can be within X seconds / milliseconds from the time the second network device receives the first request information, where X is a positive integer.

[0525] For example, the sample size of the measurement results refers to either the number of cells corresponding to the measurement results of the terminal device, or the number of beams corresponding to the measurement results of the terminal device. Specifically, the sample size of the measurement results can be expressed as the maximum sample size or the minimum sample size.

[0526] For example, the measurement result of the terminal device refers to the measurement result of the cell or beam obtained by the terminal device.

[0527] Optionally, the terminal device can be a terminal device under a specific cell or a specific beam; in this case, the specific cell is the serving cell of the terminal device; the characteristic beam is the beam in which the terminal device is located.

[0528] Optionally, before step S1701, the first network device and the second network device can exchange SSB-related information. This allows the first network device and the second network device to know each other's SSB switching status, signal coverage information, and SSB resource status (i.e., cell or beam-related information).

[0529] S1702. The second network device determines the first measurement result based on the first request information.

[0530] For example, when the first request information indicates a measurement result acquisition period, the second network device can filter the measurement information it receives from the terminal device and determine the measurement results received within the measurement result acquisition period as the measurement results of the terminal device. When the first request information indicates a measurement period, the second network device can filter the measurement information it receives from the terminal device and determine the measurement results within the measurement period as the measurement results of the terminal device. When the first request information indicates the sample size of the measurement results, the second network device can filter the measurement information it receives from the terminal device so that the measurement information of the terminal device it determines meets the requirement of the sample size of the measurement results.

[0531] For example, when the measurement results of the terminal device include the measurement results of the serving cell, the terminal device may also measure and inform the first network device of the measurement results of the neighboring cells. Alternatively, the measurement results of the neighboring cells may also be obtained by the second network device. When the measurement results of the terminal device include the measurement results of the neighboring cells, the terminal device may also measure and inform the first network device of the measurement results of the serving cell.

[0532] S1703, the second network device sends a first response message to the first network device; correspondingly, the first network device receives the first response message from the second network device. The first response message indicates the first measurement result.

[0533] S1704. The first network device determines the first channel correlation based on the first measurement result.

[0534] Optionally, when the first measurement result includes the measurement result of the serving cell, step S1704 can be replaced by: the first network device determining the first channel correlation based on the first measurement result and the measurement results of neighboring cells. When the first measurement result includes the measurement results of neighboring cells, step S1704 can be replaced by: the first network device determining the first channel correlation based on the first measurement result and the measurement result of the serving cell.

[0535] For example, the first network device may calculate the PCC based on the measurement results of the serving cell and the measurement results of neighboring cells to obtain the first channel correlation. Alternatively, the network device may determine the first channel correlation based on any other possible method, which is not limited in this application.

[0536] In another possible implementation, the first network device requests a first channel correlation from the second network device.

[0537] For example, in this possible implementation, as shown in Figure 18, the measurement method may include the following steps:

[0538] S1705, the first network device sends a second request message to the second network device; correspondingly, the second network device receives the second request message from the first network device.

[0539] The second request information indicates one or more of the following: the measurement result acquisition period, the measurement period, and the number of samples of the measurement result. The first request message is used to request the first measurement result, which includes the first channel correlation.

[0540] For example, the implementation of the measurement result acquisition period, measurement period, and sample size of the measurement results can be found in the relevant description in step S1701 above, and will not be repeated here.

[0541] For example, the second request information may also instruct the first channel correlation to be determined based on the measurement results of the terminal device. Here, the measurement results of the terminal device refer to the measurement results of the cell or beam obtained by the terminal device.

[0542] Optionally, the terminal device can be a terminal device under a specific cell or a specific beam; in this case, the specific cell is the serving cell of the terminal device; the characteristic beam is the beam in which the terminal device is located.

[0543] Optionally, before step S1705, the first network device and the second network device can exchange SSB-related information. This allows the first network device and the second network device to know each other's SSB switching status, signal coverage information, and SSB resource status (i.e., cell or beam-related information).

[0544] For example, when the second request information indicates a measurement result acquisition period, the second network device can filter the measurement information it receives from the terminal device and determine the measurement results received within the measurement result acquisition period as the measurement results of the terminal device. When the second request information indicates a measurement period, the second network device can filter the measurement information it receives from the terminal device and determine the measurement results within the measurement period as the measurement results of the terminal device. When the second request information indicates the sample size of the measurement results, the second network device can filter the measurement information it receives from the terminal device so that the measurement information of the terminal device it determines meets the requirement of the sample size of the measurement results.

[0545] For example, when the measurement results of the terminal device include the measurement results of the serving cell, the terminal device can also measure the measurement results of neighboring cells. Alternatively, the measurement results of neighboring cells can also be measured by the first network device and communicated to the first network device (e.g., the first request information indicates the measurement results of neighboring cells). When the measurement results of the terminal device include the measurement results of neighboring cells, the terminal device can also measure and communicate the measurement results of the serving cell to the first network device.

[0546] S1706. The second network device determines the first channel correlation based on the second request information.

[0547] For example, the second network device can determine the measurement results of the serving cell and / or neighboring cells based on the second request information; and determine the first channel correlation based on the measurement results of the serving cell and the neighboring cells. Specifically, the implementation of step S1706 is similar to that of step S1704, and the details can be found in the relevant description of step S1704, which will not be repeated here.

[0548] S1707, the second network device sends a second response message to the first network device; correspondingly, the first network device receives the second response message from the second network device. The second response message indicates the first channel correlation.

[0549] Combining the two possible implementation methods described above, since higher channel correlation leads to higher inter-frequency prediction accuracy, after determining the first channel correlation, the first network device can determine whether to initiate inter-frequency prediction (i.e., use the first model to predict the measurement results of neighboring cells) based on the first channel correlation. For example, after determining the first channel correlation, the measurement method may further include the following steps:

[0550] S1708, the first network device sends a first indication message to the second network device terminal device, and correspondingly, the terminal device receives the first indication message from the network device. The first indication message indicates whether to start the first model, or in other words, whether to start inter-frequency prediction.

[0551] S1709. The second network device sends a first instruction message to the terminal device, and the terminal device receives the first instruction message from the first network device.

[0552] For example, the second network device may forward the first indication information transparently; or the first indication information may be modified before being sent to the terminal device, but the modified first indication information still indicates whether to start the first model.

[0553] For example, the implementation of the first instruction information can be found in the relevant description in step S605, and will not be repeated here.

[0554] Optionally, the first network device may determine the first indication information based on the first channel correlation. For example, when the first channel correlation is greater than a first threshold, the first indication information indicates that the first model is started; when the first channel correlation is less than or equal to the first threshold, the first indication information indicates that the first model is turned off or not started.

[0555] Specifically, the first threshold can be pre-agreed upon by the terminal device or the network device; for example, it can be predefined through a protocol; or it can be determined by the terminal device and communicated to the network device; or it can be determined by the network device and communicated to the terminal device.

[0556] Optionally, after activating the first model (or, in other words, activating inter-frequency prediction, i.e., the first indication information indicates the activation of the first model), the first network device can continuously monitor the correlation between the first channel and the second channel (e.g., determine the correlation of the second channel); thereby determining whether to disable the first model. At this time, the first network device can also perform the following steps:

[0557] S1710, The first network device determines the second indication information based on the second channel correlation.

[0558] S1711, The first network device sends a second instruction message to the second network device, and correspondingly, the second network device receives the second instruction message from the first network device.

[0559] S1712, The second network device sends a second instruction message to the terminal device, and the terminal device receives the second instruction message from the first network device.

[0560] The second indication information indicates whether the first model is turned off; the second channel correlation is the correlation between the first channel and the second channel corresponding to the second measurement result; the measurement time of the second measurement result is after the first model is started; and the second measurement result includes the measurement results of the target neighboring cell.

[0561] For example, the second network device may forward the second instruction information transparently; or the second instruction information may be modified before being sent to the terminal device, but the modified second instruction information still indicates whether to close the first model.

[0562] For example, the implementation of the second measurement result can be found in the relevant descriptions in the above embodiments, and will not be repeated here.

[0563] Optionally, when the second channel correlation is greater than the first threshold, it indicates that the terminal device can still make predictions based on the first model. In this case, the second indication information can indicate that the first model should not be turned off. When the second channel correlation is less than or equal to the first threshold, it indicates that the terminal device is no longer suitable for making predictions using the first model. In this case, the second indication information can indicate that the first model should be turned off, that is, the terminal device exits inter-frequency prediction.

[0564] In some embodiments, the second channel correlation is calculated and determined by the first network device.

[0565] For example, in this embodiment, the first network device continuously monitors the correlation between the first channel and the second channel. This can also be understood as: the first network device instructs the second network device to configure a monitoring gap for the terminal device, so that the terminal device measures the signal quality of neighboring cells within the monitoring gap, thereby obtaining and reporting the measurement results of the terminal device included in the second measurement results. This allows the network device to determine the correlation of the second channel based on the second measurement results. That is, before step S1710, the measurement method may further include the following steps:

[0566] S1713, The second network device sends configuration information to the terminal device; correspondingly, the terminal device receives the configuration information sent by the second network device. The configuration information indicates the monitoring gap (GAP).

[0567] For example, the implementation of monitoring GAP can be found in the relevant description in step S609 above, and will not be repeated here.

[0568] For example, configuration information can be carried in any of the following: RRC signaling, MAC-CE signaling, or DCI.

[0569] Optionally, when the first channel correlation and the second channel correlation are determined by different network elements, for example, when the first channel correlation is determined by the second network device and the second channel correlation is determined by the first network device, the second network device can also align the relevant parameters of the first channel correlation with the first network device. This allows the first network device to measure and calculate the second channel correlation based on the same parameters as the first channel correlation, thereby avoiding the difference between the first channel correlation and the second channel correlation being too large or too small due to the influence of factors other than the channel state. This could easily lead to errors in the judgment of whether inter-frequency prediction is turned off, affecting cell handover performance.

[0570] For example, the relevant parameters for calculating the first channel correlation include the calculation method of the first channel correlation or the second channel correlation, the first indication information determined based on the first channel correlation, the measurement object corresponding to the first measurement result or the second measurement result, or the first accuracy.

[0571] The calculation methods for the first channel correlation and the second channel correlation are the same, the measurement objects corresponding to the first measurement result and the second measurement result are the same, and the first accuracy rate is the prediction accuracy rate of the first model expected by the serving cell.

[0572] For example, specifically, accuracy can be represented by RMSE. For instance, the first accuracy can be 1 dB, meaning that when the RMSE of the first model is less than or equal to 1 dB, it indicates that the prediction accuracy of the first model meets the first accuracy requirement.

[0573] S1714. The terminal device determines the second measurement result based on the configuration information.

[0574] For example, the terminal device can measure the signal quality of neighboring cells within the monitoring gap to obtain the measurement results of the neighboring cells included in the second measurement result. Specifically, the implementation of the second measurement result is similar to that of the first measurement result described above, and can be found in the relevant description of the first measurement result, which will not be repeated here.

[0575] S1715, The terminal device sends the second measurement result to the second network device; correspondingly, the first network device receives the second measurement result sent from the terminal device.

[0576] For example, the implementation of step S1715 is similar to that of step S610 above. For details, please refer to the relevant specification of step S610 below, which will not be repeated here.

[0577] S1716, The second network device sends a second measurement result to the first network device; correspondingly, the first network device receives the second measurement result sent by the second network device.

[0578] For example, the second network device can forward the second indication information transparently; or it can make some changes to the second indication information before sending it to the first network device, but the changed second indication information still indicates the measurement result of the terminal device.

[0579] S1717. The first network device determines the second channel correlation based on the second measurement result.

[0580] For example, the implementation of the first network device determining the second channel correlation based on the second measurement result is similar to the implementation of "the first network device determines the first channel correlation based on the first measurement result" in step S1704 above. For details, please refer to the relevant description in step S1704, which will not be repeated here.

[0581] In other embodiments, the second channel correlation is calculated and determined by the second network device and then communicated to the first network device.

[0582] For example, in this embodiment, the first network device continuously monitors the correlation between the first channel and the second channel. This can also be understood as: the first network device instructs the second network device to configure a monitoring gap for the terminal device, so that the terminal device measures the signal quality of neighboring cells within the monitoring gap, thus obtaining the measurement results of neighboring cells included in the second measurement result. Then, based on the second measurement result, the second channel correlation is determined and communicated to the first network device. That is, before step S1710, the measurement method may further include the following steps:

[0583] S1718, The second network device sends configuration information to the terminal device; correspondingly, the terminal device receives the second configuration information sent by the second network device.

[0584] For example, the implementation of monitoring GAP can be found in the relevant description in step S608 above, and will not be repeated here.

[0585] Optionally, when the first channel correlation and the second channel correlation are determined by different network elements, for example, when the first channel correlation is determined by the first network device and the second channel correlation is determined by the second network device, the first network device can also inform the second network device of the relevant parameters for calculating the first channel correlation through configuration information. This allows the second network device to measure and calculate the second channel correlation based on the same parameters as the first channel correlation, thereby avoiding the difference between the first channel correlation and the second channel correlation being too large or too small due to the influence of factors other than channel state. This could easily lead to errors in the judgment of whether inter-frequency prediction is turned off, affecting cell handover performance.

[0586] For example, the configuration information also indicates the calculation method of the first channel correlation or the second channel correlation, the first indication information determined based on the first channel correlation, the measurement object corresponding to the first measurement result or the second measurement result, or the first accuracy.

[0587] The calculation methods for the first channel correlation and the second channel correlation are the same, the measurement objects corresponding to the first measurement result and the second measurement result are the same, and the first accuracy rate is the prediction accuracy rate of the first model expected by the serving cell.

[0588] For example, specifically, accuracy can be represented by RMSE. For instance, the first accuracy can be 1 dB, meaning that when the RMSE of the first model is less than or equal to 1 dB, it indicates that the prediction accuracy of the first model meets the first accuracy requirement.

[0589] S1719. The terminal device determines the second measurement result based on the configuration information.

[0590] For example, the implementation of step S1719 is the same as that of step S1714 above. For details, please refer to the relevant description of step S1714, which will not be repeated here.

[0591] S1720, The terminal device sends the second measurement result to the second network device; correspondingly, the second network device receives the second measurement result from the terminal device.

[0592] Optionally, the second measurement result can be carried in any one of RRC signaling, MAC-CE signaling, UCI, PUCCH, or PUSCH.

[0593] S1721. The second network device determines the second channel correlation based on the second measurement result.

[0594] For example, the implementation of the second network device determining the second channel correlation based on the second measurement result is similar to the implementation of "the first network device determines the first channel correlation based on the first measurement result" in step S1704 above. For details, please refer to the relevant description in step S1704, which will not be repeated here.

[0595] S1722, The second network device sends a second channel correlation to the first network device; correspondingly, the first network device receives the second channel correlation from the second network device.

[0596] Optionally, the second network device sends a second channel correlation to the first network device, including: the second network device sending a second request message to the first network device, the second request message being used to request the first model to be enabled or disabled. Therefore, step S1710 can be replaced by: the second network device determining second indication information based on the request message. In this case, the second indication information can be considered as response information to the second request message (i.e., second response information).

[0597] For example, when the first model is enabled, the second request message requesting to enable the first model can be replaced with: the second request message requesting to continue using the first model for prediction, or in other words, the second request message requesting to continue starting inter-frequency prediction. When the first model is disabled, the second request message requesting to disable the first model can be replaced with: the second request message requesting to continue using the measurement GAP to measure the signal quality of the target neighboring cell, or in other words, the request message requesting not to start inter-frequency prediction.

[0598] It is understood that in both of the above embodiments, the implementation of the second indication information is described using "the first indication information indicates the start of the first model" as an example. When the first indication information indicates that the first model should not be started, the terminal device still uses the measurement GAP to measure the signal quality of the target neighboring cell. Therefore, when the channel correlation calculated based on the measurement result of the neighboring cell determined by the measurement GAP is greater than the first threshold, the first network device can instruct the terminal device to start the first model through the second network device.

[0599] Based on this second scenario, the measurement results of the serving cell and / or the serving cell can be obtained through the interaction between the network devices of the neighboring cell (such as the first network device) and the network devices of the serving cell (i.e., the second network device); wherein the neighboring cell and the serving cell have different frequency points. Specifically, when interacting between network devices, one or more of the following can be considered: measurement results obtained within a certain measurement period, measurement results obtained within a certain measurement result acquisition period, or a sufficient number of measurement result samples.

[0600] Understandably, since channel conditions are constantly changing, excessively long measurement and / or measurement result acquisition periods can reduce the accuracy of channel correlation. Therefore, it's advisable to consider calculating the first channel correlation based on measurement results obtained within a specific measurement period and those obtained within a specific result acquisition period. This avoids the accuracy of channel correlation being affected by excessively long measurement time intervals. Furthermore, insufficient sample size for measurement results can also impact the accuracy of channel correlation. Ensuring a sufficient sample size is crucial to prevent this issue from affecting the accuracy of channel correlation.

[0601] Furthermore, since the higher the channel correlation value, the higher the accuracy of inter-frequency prediction (i.e., predicting the measurement results of the target neighbor cell through the measurement results of the serving cell), it is considered that inter-frequency prediction can be used when the first channel correlation value is large, thereby reducing or decreasing the use of measurement gaps and improving the throughput of terminal devices.

[0602] Combining the two scenarios described above, in the O-RAN scenario, the network devices mentioned above (such as the network devices in Scenario 1, and the first and second network devices in Scenario 2) can include O-CU nodes and O-DU nodes. In this case, the transmit / receive actions performed by the network devices (such as transmit / receive measurement results (such as the first measurement result and / or the second measurement result), transmit / receive configuration information (such as the first configuration information and / or the second configuration information), transmit / receive indication information (such as the first indication information and / or the second indication information), transmit / receive capability information, etc.) can be performed by the O-DU nodes; the processing actions performed by the network devices (such as determining configuration information, calculating channel correlations (such as the first channel correlation and / or the second channel correlation), performing monitoring, collecting measurement results, determining indication information, etc.) can be performed by the O-CU nodes.

[0603] For example, the O-CU node may also include an O-CU-CP1 node and an O-CU-CP2 node. In this case, as shown in Figure 19, actions such as determining configuration information, calculating channel correlations (such as first channel correlation and / or second channel correlation), performing monitoring, and determining indication information can be performed by the O-CU-CP1 node. Actions such as collecting measurement results and neighbor station measurements can be performed by the O-CU-CP2 node and then communicated to the O-CU-CP1 node. In addition, the O-DU node can collect measurement results, configuration information, indication information, capability information, etc., and inform the O-CU-CP1 node of the received information. Furthermore, after determining the indication information and / or configuration information, the O-DU node can output the indication information and / or configuration information.

[0604] Since higher correlation leads to higher accuracy in inter-frequency prediction, it's advisable to enable inter-frequency prediction when the channel correlation between the serving cell and neighboring inter-frequency cells is high. This can reduce the data transmission interruption time for terminal devices and improve their throughput. In other words, how to promptly enable or disable inter-frequency prediction is a pressing issue that needs to be addressed.

[0605] Based on this, the present application provides an information indication method. After starting inter-frequency prediction (i.e. starting the first model), the method can continuously monitor the channel correlation between the first channel and the second channel (obtain the second channel correlation) and determine whether to turn off inter-frequency prediction based on the second channel correlation. This allows inter-frequency prediction to be turned off in a timely manner when the second channel correlation is small, thus ensuring the performance of cell handover.

[0606] Referring to Figure 20, an information indication method is provided according to an embodiment of this application. As shown in Figure 20, the information indication method may include the following steps:

[0607] S2001, The network device sends a first instruction message to the terminal device; correspondingly, the terminal device receives the first instruction message from the network device.

[0608] The first indication information indicates whether to start the first model. The first indication information is determined based on the first channel correlation. The first model is located in the terminal device. The first model is used to predict the measurement results of the target neighboring cell. The target neighboring cell has a different frequency point from the serving cell of the terminal device. The first channel correlation is the correlation between the first channel and the second channel corresponding to the first measurement result. The first channel is the wireless channel between the terminal device and the serving cell, and the second channel is the wireless channel between the terminal device and the target neighboring cell.

[0609] For example, the implementation of the first indication information, the first model, the target neighboring cell, the terminal device, the first measurement result, and the first channel correlation can be found in the relevant description in Scenario 1 above, and will not be repeated here.

[0610] When the first model is activated, the network device can continuously monitor whether inter-frequency prediction needs to be turned off; for example, as shown in Figure 20, this information indication method may include the following steps:

[0611] S2002, The network device sends a second instruction message to the terminal device; correspondingly, the terminal device receives the second instruction message from the network device.

[0612] The second indication information indicates whether to shut down the first model. The second indication information is determined based on the second channel correlation. The second channel correlation is the correlation between the first channel and the second channel corresponding to the second measurement result. The measurement time of the second measurement result is after the first model is started. The second measurement result includes the measurement results of the target neighboring cell. The measurement time of the second measurement result is after the measurement time of the first measurement result.

[0613] For example, the implementation of the second indication information, the second channel correlation, and the second measurement result can be found in the relevant description in Scenario 1 above, and will not be repeated here.

In addition, the steps may be performed in different orders as presented in the embodiments of this application, and it is not necessary to perform all the operations in the embodiments of this application.

[0616] The foregoing primarily describes the solutions provided in this application from the perspective of device-to-device interaction. It is understood that each device, in order to achieve the aforementioned functions, includes corresponding hardware structures and / or software modules for executing each function. Those skilled in the art should readily recognize that, based on the algorithm steps of the examples described in conjunction with the embodiments disclosed herein, this application can be implemented in hardware or a combination of hardware and computer software. Whether a function is executed in hardware or by computer software driving hardware depends on the specific application and design constraints of the technical solution. Those skilled in the art can use different methods to implement the described functions for each specific application, but such implementation should not be considered beyond the scope of this application.

[0617] This application embodiment can divide each device into functional modules according to the above method example. For example, each function can be divided into a separate functional module, or two or more functions can be integrated into one processing module. The integrated module can be implemented in hardware or as a software functional module.

[0618] With each function divided into a functional module, Figure 21 shows a communication device 210.

[0620] For example, the transceiver module 2101 can be used to execute all transceiver operations performed by the terminal device or network device (such as the first network device or the second network device) in the embodiments shown in Figures 6 to 20, and / or to support other processes of the technology described herein; the processing module 2102 can be used to execute all operations other than transceiver operations performed by the first network element in the embodiments shown in Figures 6 to 20, and / or to support other processes of the technology described herein.

[0621] Alternatively, when the processing module 2102 is replaced by a processor and the transceiver module 2101 is replaced by a transceiver, the first network element 210 involved in the embodiments of this application can also be the communication device 220 shown in FIG22.

[0622] The processor can be logic circuit 2201, and the transceiver can be interface circuit 2202. Furthermore, the communication device 220 shown in FIG22 may also include a memory 2203.

The computer-readable storage medium can also be an external storage device of the terminal, such as a plug-in hard disk, smart media card (SMC), secure digital (SD) card, flash card, etc., equipped on the terminal. Further, the computer-readable storage medium can include both the terminal's internal storage unit and external storage devices. The computer-readable storage medium is used to store the computer program and other programs and data required by the terminal.
