[0024] This disclosure provides communication methods, nodes, communication systems, storage media, and program products.

[0025] In a first aspect, embodiments of this disclosure propose a communication method, the method comprising: a first node sending a first message to a second node, the first message being used to determine whether the first node uses a first parameter to determine first information, the first parameter being a parameter configured by the second node, and the first message including the first information.

[0026] In the above embodiments, the first node can send a first message to the second node. This first message can be used to determine whether the first node uses the parameters configured by the second node (i.e., the second parameters) to determine the first information within the first message. In other words, when reporting the first information, the first node also reports whether it used the parameters configured by the second node to determine the first information. This allows the second node to perform subsequent operations more efficiently, improving communication efficiency.

[0027] In some alternative embodiments of the first aspect, the first information includes the time-domain position of the first sampling point and the time-domain position of the second sampling point, wherein the second sampling point is the M sampling points with the highest power among the N consecutive sampling points after the first sampling point, and the interval between two adjacent sampling points is determined based on k; wherein N and M are positive integers, N is greater than or equal to M, and k is a positive number; the first parameter includes at least one of the following: N; M; k.

[0028] In the above embodiments, the first information may include the time-domain location of the first sampling point and the time-domain location of the second sampling point, thereby enabling the second node to perform inference more accurately when it receives the first information and inputs it into the AI ​​model for inference. Simultaneously, for the first node, sampling-based measurement is also implemented to save power consumption. The first parameter may include at least one of N, M, and k to efficiently determine the time-domain location.

[0029] In some alternative embodiments of the first aspect, if the first message includes second information, the first message is used to determine that the first node did not use the first parameter configured by the second node to determine the first information; if the first message does not include second information, the first message is used to determine that the first node used the first parameter configured by the second node to determine the first information; the second information is different from the first information.

[0030] In the above embodiments, whether the first node uses the first parameter to determine the first information can be determined by whether the first message contains the second information. It is understood that if the first node uses the first parameter, the first message may not contain the second information to save resources. If the first node does not use the first parameter, the first message contains the second information, which may also indicate what parameter was used.

[0031] In some alternative embodiments of the first aspect, the first message includes second information, which is used to indicate whether the first node uses a first parameter configured by the second node to determine the first information.

[0032] In the above embodiments, the first message can include second information, which instructs the first node whether to use the first parameter to determine the first information. The second information can simply indicate yes or no, efficiently determining whether to use the first parameter. Furthermore, it avoids misjudgments caused by decoding failure of the first message, where the first message contains second information but it is not decoded. That is, it prevents the first node from mistakenly believing that the first message does not contain second information and using the first parameter.

[0033] In some alternative embodiments of the first aspect, the second information is used to jointly indicate whether a plurality of first parameters configured by the second node are used by the first node to determine the first information, or the second information is used to respectively indicate whether each of the plurality of first parameters configured by the second node is used by the first node to determine the first information.

[0034] In the above embodiments, multiple first parameters can be jointly indicated to save bit resources. Alternatively, each first parameter can be indicated independently to flexibly and specifically indicate the usage of the first parameters.

[0035] In some alternative embodiments of the first aspect, if any one of the plurality of first parameters is not used to determine the first information, then the second information is used to jointly indicate that the plurality of first parameters were not used to determine the first information.

[0036] In the above embodiments, if any one of the multiple first parameters is not used, the first node indicates that the first parameter is not used. This allows the second node to perform subsequent operations more accurately.

[0037] In some alternative embodiments of the first aspect, the second information is used to jointly indicate whether a plurality of first parameters configured by the second node are used by the first node to determine the first information, the second information including 1 bit.

[0038] In the above embodiment, a 1-bit indicator can be used to indicate whether the first parameter is used, thus saving bits.

[0039] In some alternative embodiments of the first aspect, the second information is used to indicate whether each of the plurality of first parameters configured by the second node is used by the first node to determine the first information, wherein the number of bits included in the second information is equal to the number of the first parameters.

[0040] In the above embodiments, the use of the first parameter can be indicated by the same number of bits as the number of the first parameter, so as to flexibly and specifically indicate the use of the first parameter.

[0041] In some alternative embodiments of the first aspect, the first message includes third information, which is used to indicate a second parameter, the second parameter being a parameter determined by the first node itself.

[0042] In the above embodiments, the first node can report parameters that it has determined itself, so that the second node can use these parameters as a reference for the next parameter configuration.

[0043] In some alternative embodiments of the first aspect, the third information is the index of the second parameter in the set of candidate parameters.

[0044] In the above embodiments, the third information can be an index in the candidate parameter set. Since the candidate parameter set is known to both the first node and the second node, the second parameter can be determined efficiently.

[0045] In some alternative embodiments of the first aspect, the third information is the interval between the second parameter and the first parameter in the candidate parameter set.

[0046] In the above embodiments, the third information can be an interval, thereby saving the bit resources required for indication.

[0047] In some alternative embodiments of the first aspect, the interval is the number of parameters that exist between the second parameter and the first parameter.

[0048] In the above embodiments, the interval can be the number of parameters. The second node can determine the second parameter from the set of candidate parameters based on the number of parameters in the interval, thereby saving the bit resources required for indication.

That is, when the first node reports the first information, it also reports whether it uses the parameters configured by the second node to determine the first information. This enables the second node to perform subsequent operations more efficiently and improves communication efficiency.

[0055] In some alternative embodiments of the first aspect, the second node is a Location Management Function (LMF).

[0056] In the above embodiment, the second node is a Location Management Function (LMF). The first node can send a first message to the LMF.

[0106] Currently, the widespread application of 5G technology is bringing tremendous changes to all aspects of people's lives. According to the vision of the International Telecommunication Union (ITU), 5G will permeate all areas of future society, building a comprehensive information ecosystem centered on the user. Specifically, 5G user experience speeds can reach 100 Mbps to 1 Gbps, supporting ultimate service experiences such as mobile virtual reality; 5G peak speeds can reach 10 Gbps to 20 Gbps, with a traffic density of 10 Mbps per square meter (m²), capable of supporting more than a thousandfold increase in mobile traffic; 5G connection density can reach 1 million connections per square meter (m²), effectively supporting massive numbers of IoT devices; 5G transmission latency can be down to the millisecond level, meeting the stringent requirements of vehicle-to-everything (V2X) and industrial control; 5G can support mobile speeds of 500 km / h, providing a good user experience even in high-speed rail environments. It is conceivable that 5G, as a representative of new infrastructure, will reshape the future information society.

[0107] In recent years, artificial intelligence (AI) technology has made continuous breakthroughs in multiple fields. The ongoing development of fields such as intelligent voice and computer vision has not only brought a wide variety of applications to smart terminals, but has also found widespread use in education, transportation, home, healthcare, retail, security, and many other sectors, bringing convenience to people's lives while promoting industrial upgrading across various industries. AI technology is also accelerating its cross-disciplinary integration with other disciplines, combining knowledge from different fields while providing new directions and methods for the development of various disciplines.

[0108] Recent research has introduced AI technology into wireless air interfaces and investigated how AI can assist in improving wireless transmission technology. This includes, for example, the following three aspects:

[0109] AI-enabled connectivity. This means using AI to improve communication performance, such as using AI for beam management.

[0110] Computing power services. This refers to the network side providing computing power to the terminal side, such as helping the terminal with model training and inference.

[0111] Ultimate AI service. This involves enhancing the network transmission pipeline to improve the user experience of AI application services.

[0112] In some embodiments, the basic principle of AI technology is to train an AI model whose input is the measurement results and whose output is the desired information. For example, taking AI-based positioning as an example, the model's input is the measurement results based on positioning reference signals, and the model's output is the AI ​​positioning coordinates or intermediate parameters used for AI positioning. The relevant measurement results input to the AI ​​model may be time-sampled measurement results.

[0113] In some embodiments, the definition of sample is as follows:

[0114] The measured values ​​consist of Nt' values ​​of the estimated channel response in the time domain. The Nt' values ​​are selected from a list of Nt consecutive channel response values ​​with a timing granularity T.

[0115] The timing information for Nt' values ​​is reported in timing granularity T, where T = 2k x Tc. k represents the timing reporting granularity factor. Tc is the basic time unit of NR.

[0116] The relevant measurement (e.g., power, if reported) corresponds to the measured value of the reported Nt'.

[0117] The timing information is defined relative to a reference time, the same as path-based measurements.

[0118] The selected time-domain channel measurement value, Nt', is expected to be the highest power value.

[0119] The start time of the Nt consecutive value list is determined as follows: start time = the first detected path, rounded using the timing granularity T.

[0120] The Location Management Function (LMF) can send parameter value signals of Nt, Nt', and k to the gNB via NRPPa. Candidate setting values:

[0121] Nt'<=24.FSS:Nt'values ​​(values);

[0122] Nt = {32, 64, 128}

[0123] FFS:k;

[0124] gNB / TRP can use different Nt', Nt, and / or k values ​​instead of the signal parameters used for measurement reporting. In this case, the reported measurement results are processed by the LMF implementation.

[0125] Here, FFS indicates whether to transmit offset from gNB to LMF.

[0126] In some embodiments, the LMF configures sample-based measurement parameters, including Nt, Nt',k, for the gNB or UE. However, on the other hand, the base station may use different Nt, Nt',k parameters depending on the actual situation during measurement, deviating from the LMF configuration. In this case, the LMF is unaware whether the base station or UE has used the parameters configured by the LMF, leading to a decrease in communication efficiency.

[0127] Therefore, this disclosure provides a communication method in which a first node can send a first message to a second node. The first message can be used to determine whether the first node uses parameters configured by the second node (i.e., second parameters) to determine the first information in the first message. In other words, when reporting the first information, the first node also reports whether it uses the parameters configured by the second node to determine the first information. This enables the second node to perform subsequent operations more efficiently, improving communication efficiency.

[0128] Figure 1 is a schematic diagram of a communication system architecture according to an embodiment of the present disclosure.

[0129] As shown in Figure 1, the communication system 100 includes a first node 101 and a second node 102.

For example, for AI-based positioning, the second node 102 may be an LMF; for other AI-based capabilities, the second node 102 may be other network functions.

[0135] In some embodiments, the access network device may be composed of a central unit (CU) and a distributed unit (DU). The CU may also be called a control unit. The CU-DU structure can separate the protocol layer of the access network device. Some of the protocol layer functions are centrally controlled by the CU, while the remaining part or all of the protocol layer functions are distributed in the DU and centrally controlled by the CU. However, this is not the only possibility.

[0140] Figure 2a is a schematic diagram of a communication method interaction according to an embodiment of the present disclosure. As shown in Figure 2a, this embodiment of the present disclosure relates to a communication method for a communication system 100, the method including:

[0141] Step S2101: The second node 102 configures the first parameter to the first node 101.

[0142] In some embodiments, the first node 101 receives a first parameter configured by the second node 102.

[0143] In some embodiments, the first parameter can be used to determine first information. In this disclosure, the parameter configured by the second node for determining the first information is referred to as the first parameter. The first information can also be called measurement information or measurement results. The first information can be input into an AI model for AI inference. For example, for AI-based positioning, the first information is input into the AI ​​model, and the AI ​​model can output positioning information or intermediate parameters used for positioning.

[0144] It is understood that, for sampling-based measurements, the first information may include the time-domain location of the first sampling point and the time-domain location of the second sampling point. Therefore, the second node may configure a first parameter to the first node so that the first node can determine the time-domain location of the first sampling point and / or the time-domain location of the second sampling point based on the first parameter.

[0145] In some embodiments, for sampling-based measurements, each resource location can be understood as a point. Selecting a subset of resource locations from multiple resource locations constitutes sampling, and the selected resource locations are called sampling points. Resource locations are used to transmit or receive reference signals, and measuring the reference signals at the selected resource locations constitutes sampling-based measurement. Resource locations may include time-domain resource locations (or simply time-domain locations), frequency-domain resource locations (or simply frequency-domain locations), etc. The first information may include the time-domain location of the first sampling point and the time-domain location of the second sampling point.

[0146] Figure 2b is a schematic diagram of the first and second sampling points according to an embodiment of the present disclosure. As shown in Figure 2b, among the N consecutive sampling points after the first sampling point, the M sampling points with the highest power are the second sampling points.

[0147] In some embodiments, the second sampling point is the M (or Nt', not limited thereto) sampling points with the highest power among the N (or Nt, not limited thereto) consecutive sampling points following the first sampling point. N and M are positive integers, and N is greater than or equal to M. The interval between two consecutive sampling points can be determined based on k. The first parameter may include at least one of N, M, and k.

[0148] Step S2102: First node 101 determines first information.

[0149] In some embodiments, the first information includes the time-domain location of the first sampling point and the time-domain location of the second sampling point.

[0150] Optionally, the temporal location of the first sampling point can be determined as follows: the second node can indicate an offset to the first node. The first node can determine the temporal location of the first sampling point based on the offset and the reference temporal location. The offset can be a temporal unit or the number of sampling points. The temporal unit can be a time slot, a symbol, etc., but is not limited to these.

[0151] For example, the time domain position of the first sampling point is the position starting from the reference time domain position and spaced X time slots apart.

[0152] For example, the time-domain position of the first sampling point is the position starting from the reference time-domain position and spaced X sampling points apart. The interval between two adjacent sampling points can be determined based on k. For example, two adjacent T=2 k xTc, where x is the multiplication sign and Tc is the basic time unit of NR. The time-domain position of the first sampling point can be a position starting from the reference time-domain position and spaced at (X+1)*T intervals. That is, the first node can determine T based on k, and determine the time-domain position of the first sampling point based on T. The first parameter can include k, then the first node can determine the first information based on the first parameter.

[0153] Optionally, the temporal location of the second sampling point can be determined as follows: Based on M and N, the first node determines the M sampling points with the highest power from the N consecutive sampling points following the first sampling point; these are the second sampling points. The temporal location of the second sampling point is then determined according to the temporal location of the first sampling point and the interval between two adjacent sampling points.

[0154] For example, assuming N = 32 and M = 8, the 32 sampling points can be indicated using indices 0 to 31, and the index values ​​of the second sampling points are assumed to be 0, 2, 3, 5, 8, 9, 20, and 25. The temporal position of the first second sampling point is a position starting from the reference temporal position and spaced T apart. The second second sampling point (i.e., the sampling point with index 2) is the third sampling point after the first sampling point, and its temporal position is a position starting from the reference temporal position and spaced T*2 apart. This disclosure does not provide a complete list of examples, but is not limited thereto. The first parameter may include at least one of N, M, and k, and the first node can determine the first information based on the first parameter.

[0155] It is understood that the first information can be determined based on a first parameter or other parameters. For example, the first information can be determined based on a second parameter, which may include at least one of N, M, and k. The second parameter is determined by the first node itself. As another example, the first information can be determined based on a third parameter, which may include at least one of N, M, and k. The third parameter is a parameter predefined in the protocol. This disclosure does not provide examples of all such cases, but it is not limited to these. That is to say, the first node may not necessarily use the first parameter to determine the first information; it may use the second parameter or other parameters to determine the first information. Therefore, the first node can indicate whether to use the first parameter to determine the first information while sending the first information. For example, the first node can send a first message to the second node, the first message including the first information, and the first message being used to determine whether the first node uses the first parameter to determine the first information.

[0156] In step S2103, the first node 101 sends a first message to the second node 102.

[0157] In some embodiments, the second node 102 receives a first message sent by the first node 101.

[0158] In some embodiments, the first message is used to determine whether the first node uses a first parameter to determine the first information. The first parameter is a parameter configured by the second node, and the first message includes the first information.

[0159] The first node can report the first information to the second node, so as to make AI inference more accurate and efficient.

[0160] In some embodiments, the first message may implicitly indicate whether the first node uses the first parameter configured by the second node to determine the first information.

[0161] Optionally, if the first message includes second information, then the first message is used to determine that the first node did not use the first parameter configured by the second node to determine the first information; if the first message does not include second information, then the first message is used to determine that the first node used the first parameter configured by the second node to determine the first information; the second information is different from the first information. That is, if the first node determines the first information based on the first parameter, then the first message may not include the second information. The second node determines that the first node used the first parameter to determine the first information based on the absence of second information in the first message. If the first node determines the first information based on the second parameter or other parameters, i.e., it did not use the first parameter to determine the first information, then the first node may include the second information in the first message, and the second node determines that the first node did not use the first parameter to determine the first information based on the inclusion of second information in the first message.

[0162] Optionally, the second information is information different from the first information. For example, the second information may indicate the parameters used to determine the first information. When the first message contains the second information, the second node can determine that the first node did not use the first parameter to determine the first information, and can determine, based on the second information, which parameters the first node used to determine the first information. Conversely, if the first message does not contain the second information, the second node may default to the first node using the first parameter to determine the first information. For another example, the second information may be X bits, which can be used to indicate which one or more of the multiple first parameters configured by the second node were not used to determine the first information. Then, when the first message contains the second information, the second node can determine that the first node did not use the first parameter to determine the first information, and can determine, based on the second information, which specific second parameters were not used to determine the first information. Conversely, if the first message does not contain the second information, the second node may default to the first node using the first parameter to determine the first information. It is understood that the specific form of the second information is not limited in this disclosure.

[0163] In some embodiments, the first message can explicitly indicate whether the first node uses the first parameter configured by the second node to determine the first information.

[0164] Optionally, the first message includes second information, which is used to indicate whether the first node uses the first parameter configured by the second node to determine the first information. For example, regardless of whether the first node uses the first parameter to determine the first information, the first message includes second information, and different values ​​of the second information are used to indicate whether the first node uses the first parameter to determine the first information.

[0165] Optionally, the second information is used to jointly indicate whether the first node uses multiple first parameters configured by the second node to determine the first information. For example, suppose there are three first parameters, namely M, N, and k. The second information can be 1 bit. When the 1 bit is a first value, the first parameters M, N, and k are not used to determine the first information. When the 1 bit is a second value, the first parameters M, N, and k are all used to determine the first information. The first value can be, for example, 0, and the second value can be, for example, 1, but is not limited to these.

[0166] Optionally, the second information is used to indicate whether each of the plurality of first parameters configured by the second node is used by the first node to determine the first information. This indication can also be called an independent indication. For example, suppose there are three first parameters, M, N, and k. The second information can be 3 bits, with each bit corresponding to one parameter. For example, the 3 bits from right to left correspond to M, N, and k respectively. If the 3 bits are 001, it indicates that M is used to determine the first information, while N and k are not. If the 3 bits are 101, it indicates that M and k are used to determine the first information, while N is not. This disclosure does not provide a complete list of examples, but is not limited to these.

[0167] In some embodiments, the first parameter includes at least one of the following: N; M; k. The first parameter can determine the time-domain position Y of the second sampling point based on the time-domain position X of the first sampling point. For example, k can be used as the interval between two adjacent sampling points. M and N can be used to determine the second sampling point, that is, to determine how many consecutive sampling points after the first sampling point the second sampling point is among the sampling points with the highest power.

[0168] For example, the interval T = 2 between two adjacent sampling points k xTc, where x is the multiplication sign and Tc is the basic time unit of NR. Assuming N = 32 and M = 8, the 8 highest-power sampling points are determined from the 32 consecutive sampling points following the first sampling point; these are the 8 second sampling points. These 32 sampling points can be indicated using indices 0 to 31. Assuming the indices of the 8 second sampling points are 0, 2, 3, 5, 8, 9, 20, and 25 respectively, the first second sampling point (i.e., the sampling point with index 0) is the first sampling point after the first sampling point, and its time-domain position is Y1 = (X + T). The second second sampling point (i.e., the sampling point with index 2) is the third sampling point after the first sampling point, and its time-domain position is Y2 = (X + T * 2). This disclosure does not provide a complete list of examples, but is not limited to this.

[0169] In some embodiments, the first message includes third information, which is used to indicate a second parameter, the second parameter being a parameter determined by the first node itself. For example, if the first node uses the second parameter to determine the first information, the first message can include third information to indicate the second parameter, that is, to inform the second node what parameter determined the first information.

[0170] In some embodiments, the third information and the second information can be the same information. For example, if the first message contains third information, the second node can determine that the first node did not use the first parameter to determine the first information. Conversely, if the first message does not contain third information, the second node can determine that the first node used the first parameter to determine the first information.

[0171] In some embodiments, the second parameter includes at least one of the following: N; M; k. It is understood that the second parameter is similar to the first parameter, and will not be described again in this disclosure. It is understood that the types of multiple parameters included in the first and second parameters may be the same, but this does not mean that their values ​​are the same. For example, the N of the first parameter may be N1, and the N of the second parameter may be N2. N1 and N2 may be the same or different. Exemplarily, if N1 and N2 are the same, the first node uses N1 to determine the first information, and the first message may not include the third information. The second node can determine that the first node used N1 to determine the first information. If N1 and N2 are different, the first node uses N2 to determine the first information, and the first message includes the third information, which is used to indicate N2. The second node can determine that the first node used N2 to determine the first information based on the third information. Other parameters (M, k, etc.) are similar to N and will not be described again. It is understood that the above examples are merely illustrative. Even when N1 and N2 are different, the first node can also use N1 to determine the first information, and this disclosure does not limit this.

[0172] In some embodiments, the third information is the index of the second parameter in the candidate parameter set. Taking M as an example, the candidate parameter set is the candidate M set, which can also be understood as the set of values ​​for M, or the range of possible values ​​for M, etc. Assuming the candidate M set is {24, 20, 16, 12, 8, 4}, with a total of 6 candidate values, the first node can use 3 bits (rounded up from log26) to indicate the value of M.

[0173] In some embodiments, the third information is the interval between the second parameter and the first parameter in the candidate parameter set. Taking M as an example, the candidate parameter set is the candidate M set, which can also be understood as the set of values ​​for M, or the range of possible values ​​for M, etc. Assuming the candidate M set is {24, 20, 16, 12, 8, 4}, if the first parameter is 12, when the interval is +1, the second parameter can be determined to be a value after 12, i.e., 8. When the interval is -1, the second parameter can be determined to be a value before 12, i.e., 16. This disclosure does not provide all examples, but is not limited to these.

[0174] In some embodiments, the names of the first message, first information, second information, and third information are not limited. For example, the first message may also be called a first report, a reporting message, etc. The first information may also be called measurement information, measurement result, etc. The second information may also be called indication information, etc. The third information may also be called indication information, etc.

[0175] In some embodiments, the second node receives the first message and obtains first information from it, and can perform AI inference based on the first information. For example, for AI-based positioning, the second node can input the first information into the AI ​​model to obtain the positioning information output by the AI ​​model or intermediate parameters used for positioning.

[0176] In some embodiments, if a second node receives a first message and obtains first information from it, but does not obtain second information, the second node can determine that the first node used the first parameter to determine the first information, and then perform AI deduction based on the first information. In other words, the second node can perform AI deduction based on the first information if it determines that the first node used the first parameter to determine the first information, thus ensuring the reliability of the first information.

[0177] In some embodiments, if a second node receives a first message and obtains first information and second information from it, the second node can determine that the first node did not use the first parameter to determine the first information, and thus can perform AI deduction without relying on the first information.

[0178] In some embodiments, the second node receives first information and obtains first information and second information from it, where the second information includes a second parameter. The second node can then determine that the first node did not use the first parameter to determine the first information and that the first node determined the first information based on the second parameter. The second node can store the value corresponding to the second parameter and use this value as a candidate value for the first parameter. That is, the second node can use the parameter determined by the first node itself as a candidate first parameter, which can be configured to the first node in subsequent communication processes to help the first node determine the first information more accurately and save the resources of the first node reporting parameters. In some embodiments, the first node can determine the first information based on at least one type of parameter among the first, second, and third parameters, and report the first information to the second node for training an AI model. For example, the first node can receive the first parameter, determine the second parameter itself, determine the third parameter based on a predefined protocol, determine the first information based on at least one of the first, second, and third parameters, and report the first information to the second node. The second node can determine the required information in a non-AI manner; for example, in a positioning scenario, the required information is positioning information or intermediate parameters used for positioning. The second node can also obtain the required information reported by the first node. The second node inputs the first information into the AI ​​model and makes the output of the AI ​​model approximate the required information, thereby training the AI ​​model.

[0179] In some embodiments, the first node can determine first information based on a first parameter, a second parameter, and a third parameter, and send the first information determined by each type of parameter to the second node. The second node can train an AI model for each type of parameter. For example, the first information determined by the first parameter can be input into the AI ​​model to train an AI model for the first parameter, assuming it is the first model. The first information determined by the second parameter can be input into the AI ​​model to train an AI model corresponding to the second parameter, assuming it is the second model. The first information determined by the third parameter can be input into the AI ​​model to train an AI model corresponding to the third parameter, assuming it is the third model. Thus, after the first node reports the first information, the corresponding AI model can be selectively input for derivation, resulting in more accurate and efficient derivation.

[0180] In some embodiments, if the second node determines that the first node used the first parameter to determine the first information, then the first information can be input into the first model. If the second node determines that the first node did not use the first parameter to determine the first information, but used the second parameter to determine the first information, then the first information can be input into the second model. Correspondingly, if the second node determines that the first node did not use the first parameter to determine the first information, but used the third parameter to determine the first information, then the first information can be input into the third model.

[0216] This disclosure provides a measurement result indication method, in which a base station or terminal sends a first message to a first network element (LMF). The message includes first information, which indicates whether the base station or terminal uses a first parameter configured by the LMF and / or a first parameter value determined by the base station or terminal itself.

[0222] In some embodiments, the first information explicitly indicates whether a first parameter configured by the LMF is used. For multiple first parameters, the first information may indicate jointly or independently.

[0223] For example, parameters Nt, Nt', k can be indicated using 3-bit independent pointers or 1-bit combined pointers. With combined pointers, the combined pointers differ if any one of the parameters differs from the LMF.

[0224] In some embodiments, in response to a first parameter determined by the base station / terminal itself indicated in a first message, the following two methods are considered.

[0225] Optionally, the terminal or base station can directly indicate the first parameter determined by itself. For example, if the range of possible values ​​for Nt' includes {24, 20, 16, 12, 8, 4}, then the terminal or base station can directly use 3 bits to indicate the selected value.

[0226] Optionally, an offset based on the LMF configuration value can be indicated, for example, two predefined offsets, [-1, +1]. -1 represents the preceding value of the LMF indicator in the parameter set, and +1 represents the following value of the LMF indicator in the parameter set. For example, if the LMF is configured as 12, then offset -1 represents 16, and offset +1 represents 8.

[0227] This disclosure also provides an apparatus for implementing any of the above methods. For example, an apparatus is provided that includes units or modules for implementing the steps performed by the terminal in any of the above methods. Alternatively, another apparatus is provided that includes units or modules for implementing the steps performed by a network device (e.g., an access network device, a core network functional node, a core network device, etc.) in any of the above methods.

[0228] It should be understood that the division of units or modules in the above device is only a logical functional division. In actual implementation, they can be fully or partially integrated into a single physical entity, or they can be physically separated. Furthermore, the units or modules in the device can be implemented by a processor calling software: for example, the device includes a processor connected to a memory containing instructions. The processor calls the instructions stored in the memory to implement any of the above methods or to implement the functions of the units or modules in the above device. The processor can be, for example, a general-purpose processor, such as a Central Processing Unit (CPU) or a microprocessor, and the memory can be internal or external to the device. Alternatively, the units or modules in the device can be implemented in the form of hardware circuits. The functionality of some or all of the units or modules can be achieved through the design of these hardware circuits, which can be understood as one or more processors. For example, in one implementation, the hardware circuit is an application-specific integrated circuit (ASIC). The functionality of some or all of the units or modules is achieved through the design of the logical relationships between the components within the circuit. In another implementation, the hardware circuit can be implemented using a programmable logic device (PLD). Taking a field-programmable gate array (FPGA) as an example, it can include a large number of logic gates. The connection relationships between the logic gates are configured through configuration files, thereby achieving the functionality of some or all of the units or modules. All units or modules of the above device can be implemented entirely through processor-called software, entirely through hardware circuits, or partially through processor-called software with the remaining parts implemented through hardware circuits.

[0229] In this embodiment, the processor is a circuit with signal processing capabilities. In one implementation, the processor can be a circuit with instruction read and execute capabilities, such as a Central Processing Unit (CPU), a microprocessor, a graphics processing unit (GPU) (which can be understood as a microprocessor), or a digital signal processor (DSP). In another implementation, the processor can implement certain functions through the logical relationships of hardware circuits. The logical relationships of the aforementioned hardware circuits are fixed or reconfigurable. For example, the processor is a hardware circuit implemented using an application-specific integrated circuit (ASIC) or a programmable logic device (PLD), such as an FPGA. In a reconfigurable hardware circuit, the process of the processor loading a configuration document and configuring the hardware circuit can be understood as the process of the processor loading instructions to implement the functions of some or all of the above units or modules. Furthermore, it can also be a hardware circuit designed for artificial intelligence, which can be understood as an ASIC, such as a Neural Network Processing Unit (NPU), a Tensor Processing Unit (TPU), or a Deep Learning Processing Unit (DPU).
