In the following description, when referring to the drawings, like numbers in different figures represent like or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all possible embodiments consistent with the present invention. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present invention, as detailed in the appended claims.

[0228] Deep neural network models are highly capable of complex data processing and feature modeling, and are currently being applied to solve many key problems in wireless communications. Terminal positioning based on artificial intelligence (AI) is a key application of AI technology in the communications field and a key research direction of the Third Generation Partnership Project (3GPP). Currently, AI-based positioning methods can achieve higher positioning accuracy than traditional positioning methods.

[0229] Research on AI-based terminal positioning technology mainly considers two specific implementation methods, including direct positioning based on AI models and indirect positioning assisted by AI models, as shown in Figure 1B.

[0230] (1) Direct positioning based on AI model: The input of AI positioning model is the channel measurement data used for positioning, and the output is the positioning result, that is, the terminal location coordinates;

[0231] (2) Indirect positioning assisted by AI models: The input of the AI ​​model is the channel measurement data used for positioning, and the output is intermediate positioning parameters, which can include time of arrival (ToA), angle of arrival (AoA), etc. Based on these intermediate parameters, traditional positioning methods such as time difference of arrival (TDOA) can be used to calculate the terminal position coordinates, that is, the positioning results.

[0232] In the above-mentioned direct positioning method and indirect positioning method, the input of the AI ​​model is the channel measurement data used for positioning, and the channel measurement data may be a channel impulse response (CIR) calculated based on a positioning reference signal.

[0233] In addition, depending on the specific device implementing positioning, AI-based terminal positioning can be implemented on the terminal, access network equipment, or core network equipment, such as the Location Management Function (LMF). Therefore, the AI-based terminal positioning solution includes but is not limited to five specific application modes, such as those shown in Figure 1C.

[0234] Mode 1: Direct or indirect positioning on the terminal side.

[0235] The terminal calculates positioning measurements, such as the CIR, based on the Positioning Reference Signal (PRS) sent by the access network device. These measurements are then fed into an AI model to directly obtain the terminal's location coordinates. Alternatively, the terminal feeds these measurements into the AI ​​model to obtain intermediate positioning parameters, such as ToA and AoA, and then uses traditional positioning methods such as TDOA to obtain the terminal's location coordinates. After obtaining the positioning results, i.e., the location coordinates, the terminal reports them to the LMF.

[0236] Mode 2: Terminal-assisted LMF side indirect positioning.

[0237] The terminal calculates the measurement value used for positioning, such as CIR, based on the PRS sent by the access network device, inputs the AI ​​model to obtain intermediate positioning parameters such as ToA and AoA, and reports the intermediate positioning parameters to LMF. LMF uses traditional positioning methods such as TDOA to obtain the terminal location coordinates.

[0238] Mode 3: Terminal-assisted direct positioning on the LMF side.

[0239] The terminal calculates the measurement value used for positioning, such as CIR, based on the PRS sent by the access network device, and reports the measurement value used for positioning to the LMF. The LMF inputs the received measurement value into the AI ​​model to obtain the terminal location coordinates.

[0240] Mode 4: Indirect positioning on the LMF side assisted by access network equipment.

[0241] The access network equipment calculates the measurement values ​​used for positioning, such as CIR, based on the Sounding Reference Signal (SRS) sent by the terminal, inputs the positioning measurement values ​​into the AI ​​model to obtain intermediate positioning parameters such as ToA and AoA, and reports the intermediate positioning parameters to the LMF. The LMF uses traditional positioning methods such as TDOA to obtain the terminal location coordinates.

[0242] Mode 5: Direct positioning on the LMF side assisted by access network equipment.

[0243] The access network equipment calculates the measurement values ​​used for positioning, such as CIR, based on the SRS sent by the terminal, and reports the measurement values ​​used for positioning to the LMF. The LMF inputs the positioning measurement values ​​into the AI ​​model to directly obtain the terminal location coordinates.

[0244] In the five modes described above, data acquisition and model inference may be implemented on different devices. For application modes 1, 2, and 4, the channel measurement data required for the AI ​​positioning model is obtained by the terminal and access network equipment based on positioning reference signal measurements. The AI ​​model is also deployed on the terminal or access network equipment. Therefore, the terminal or access network equipment can directly input its acquired channel measurement data into the AI ​​positioning model to obtain positioning results, without involving the reporting and transmission of the channel measurement data used for positioning.

[0245] For the above-mentioned modes 3 and 5, the channel measurement data used for AI positioning needs to first be calculated and obtained by the terminal or access network equipment based on the positioning reference signal, and then reported to the LMF. The LMF inputs the AI ​​positioning model and obtains the positioning result, that is, the target terminal position coordinates.

[0246] The main application process of the deep learning-based terminal positioning solution is: after using training data to complete the AI ​​network model training (Model Training) for terminal positioning, the trained AI positioning model is deployed on the terminal, access network equipment or LMF, and then the terminal positioning work in the actual system is completed, that is, model inference (Model Inference) is performed.

[0247] For AI-based terminal positioning in application modes 3 and 5, the channel measurement data used for positioning must first be reported by the terminal or access network equipment to the LMF. The LMF then inputs the AI ​​model to complete model inference and obtain positioning accuracy. Currently, research on AI-based terminal positioning typically uses the channel impulse response (CIR) calculated based on the positioning reference signal as the input to the AI ​​model.

[0248] The channel impulse response (CIR) indicates the effects on the signal during channel propagation and reflects changes that occur to the signal after it propagates through the channel. This includes the attenuation of the pulse signal energy due to path loss and shadow fading, and the superposition of multiple different pulse signals received at the receiver due to the presence of multiple propagation paths in the channel.

[0249] However, the dimension of the original CIR data is large. If the terminal or access network equipment directly reports the complete CIR data to the LMF, it will cause a large data transmission overhead, which is not conducive to the application of AI-based positioning technology in actual communication systems.

[0250] The present disclosure provides an information transmission method and device, and a storage medium, which can effectively reduce the data transmission overhead of positioning while ensuring positioning accuracy, and is conducive to promoting the availability of artificial intelligence-based positioning solutions.

[0251] Furthermore, before introducing the solutions provided by the present disclosure, it should be noted that, in an embodiment of the present disclosure, terminal 101 may determine first data with a smaller data size based on CIR data and send the data to core network device 102-2 via access network device 102-1. Alternatively, access network device 102-1 may determine first data with a smaller data size based on CIR data and send the data to core network device 102-2. Core network device 102-2 may include, but is not limited to, an LMF, and a neural network for terminal positioning may be deployed on core network device 102-2.

[0252] The following describes the solutions of the present disclosure with respect to different execution entities for determining the first data.

[0253] When the first data is determined by the terminal 101, FIG2A is an interactive diagram of an information transmission method according to an embodiment of the present disclosure. As shown in FIG2A, the embodiment of the present disclosure relates to an information transmission method, and the above method includes:

[0254] In step S2101 , the access network device 102 - 1 sends a positioning reference signal to the terminal 101 .

[0255] In some embodiments, the access network device 102 - 1 sends a PRS to the terminal 101 .

[0256] In some embodiments, the number of access network devices 102 - 1 may be one or more.

[0257] In some embodiments, terminal 101 receives the PRS.

[0258] In some embodiments, the terminal 101 receives PRSs sent by one or more access network devices 102 - 1 .

[0259] In step S2102, the terminal 101 determines CIR data based on the positioning reference signal.

[0260] In some embodiments, the terminal 101 may calculate CIR data of each time domain sampling point in a plurality of time domain sampling points based on the PRS sent by each access network device 102 - 1 .

[0261] In some embodiments, the CIR data is associated with the number of transmission and receiving points (TRPs) and the number of time domain sampling points. The TRP refers to a device that sends a positioning reference signal, and in the embodiment of the present disclosure, it refers to the access network device 102-1.

[0262] In some embodiments, the CIR data includes but is not limited to power information, phase information, and delay information of each time domain sampling point.

[0263] Step S2103: Terminal 101 determines first data based on the CIR data.

[0264] In some embodiments, the first data is used for terminal positioning.

[0265] In some embodiments, the first data is data uploaded by the terminal 101 to the LMF for terminal positioning. The first data can be used as an input value of the AI ​​neural network deployed on the LMF.

[0266] In some embodiments, the data size of the first data is smaller than the data size of the CIR data.

[0267] In some embodiments, the first data may include a first number of power values, where the first number is smaller than the total number of time-domain sampling points.

[0268] In some embodiments, the first data may include serial numbers of a first number of time-domain sampling points, where the first number is smaller than the total number of time-domain sampling points.

[0269] In some embodiments, the first data may include a first number of power values ​​and a first number of numbers of time-domain sampling points, wherein the first number is smaller than the total number of time-domain sampling points.

[0270] For example, the first number may be much smaller than the total number of time-domain sampling points. For example, if the number of time-domain sampling points is 200, the first number may be 8 or 16.

[0271] In some embodiments, when the first data includes a first number of power values ​​and a first number of time-domain sampling point numbers, the data type of the first data may be a first type, which may be called a power delay profile (PDP).

[0272] In some embodiments, the name of the first type is not limited and can be interchangeable with PDP, first data type, etc.

[0273] In some embodiments, when the first data includes numbers of a first number of time-domain sampling points, the data type of the first data may be a second type, which may be called a delay profile (DP).

[0274] In some embodiments, the name of the second type is not limited and can be interchangeable with DP, second data type, etc.

[0275] In some embodiments, the name of the first data is not limited and can be interchangeable with PDP data, DP data, processed data, associated data, etc.

[0276] In some embodiments, the terminal 101 may calculate the modulus of the CIR data corresponding to each time domain sampling point and determine the modulus as the power value corresponding to the time domain sampling point. Since CIR is a complex number, the modulus r of the CIR data corresponding to each time domain sampling point may be calculated using the following formula 1:

[0277] Where a is the real part of the CIR data, and b is the imaginary part of the CIR data.

[0278] Furthermore, the first number of power values ​​may be determined according to the order of the power values ​​corresponding to each time domain sampling point from large to small, and the numbers of the first number of time domain sampling points corresponding to the first number of power values ​​may be determined.

[0279] Step S2104: Terminal 101 sends first data.

[0280] In some embodiments, the terminal 101 sends first data to the access network device 102-1, and the access network device 102-1 sends the first data to the core network device 102-2, where the core network device 102-2 may be a LMF.

[0281] In some embodiments, after receiving the first data, the access network device 102 - 1 sends the first data to the core network device 102 - 2 .

[0282] In some embodiments, the first data includes a first number of power values, and the terminal 101 may send a second number of bits to the access network device 102 - 1 , where the second number of bits is used to indicate the first number of power values.

[0283] Exemplarily, the second number is the product of the first number and a third number, and the third number is the number of bits occupied by any one of the power values ​​of the first number.

[0284] For example, the first number is N and the third number is N b , the second number is N×N b In the second number of bits, every N b bits are used to indicate the i-th power value in the first number of power values, where i is 1, 2, ... N. b bits are used to indicate the first power value, the (N b +1) to 2N b bits are used to indicate the second power value, and so on.

[0285] In some embodiments, the first data includes the numbers of the first number of time domain sampling points. The terminal 101 may send the numbers of the first number of time domain sampling points to the access network device 102-1 in any of the following ways:

[0286] Method 1: Terminal 101 sends a bitmap.

[0287] The number of bits occupied by the bitmap is equal to the total number of time domain sampling points N t For example, N t is 100, the number of bits occupied by the bitmap is 100.

[0288] The bit values ​​corresponding to the first number of time domain sampling points in the bitmap are first values, which may be 1 or 0, and are not limited in this disclosure. The bit values ​​corresponding to the other time domain sampling points in the bitmap are second values, which are different from the first values.

[0289] For example, the total number of time domain sampling points is 100, where the first number of time domain sampling points are numbered 1, 10, 20, 30, 40, 50, 60, and 70, the first value is 1, and the second value is 0. Then, the bitmap is as follows:

[0290] 10000000010000000000100000000001000000000010000000000100000000001000000000000000000000000000.

[0291] Method 2: Terminal 101 sends a first number of bit vectors.

[0292] Each bit vector is used to indicate the number of a time domain sampling point included in the first data, and the number of bits occupied by each bit vector is determined based on the total number of time domain sampling points. The number of bits occupied by each bit vector can be log2N t , where N t is the total number of time domain sampling points. The i-th bit vector represents the number of the i-th time domain sampling point.

[0293] For example, N t The first number is 8, and the corresponding time domain sampling points are numbered 1, 7, 8, 15, 23, 32, 45, and 64, respectively. The first bit vector can be used to indicate the number of the first time domain sampling point, for example, 000001, and so on.

[0294] In one example, terminal 101 sends a first number of power values ​​and the numbers of the first number of time-domain sampling points to access network device 102-1, which then sends them to a core network device, such as an LMF. The numbers of the first number of time-domain sampling points are sent to access network device 102-1 in the form of a bitmap. The order of the first number of power values ​​indicated in the second number of bits must match the order of the numbers of the first number of time-domain sampling points in the bitmap.

[0295] For example, the terminal 101 determines 8 power values ​​in the 200 time domain sampling points in descending order of power value. Assume that the corresponding time domain sampling points are numbered 1, 10, 20, 30, 40, 50, 60, and 70. The first value is 1 and the second value is 0. Then the bitmap is as follows:

[0296] 10000000010000000000100000000001000000000010000000000100000000001000000000000000000000000000.

[0297] Of the second number of bits sent by terminal 101, bits 1 to N b bits are used to indicate the power value corresponding to the time domain sampling point numbered 1, and the (N b +1) to 2N b bits are used to indicate the power value corresponding to the time domain sampling point numbered 10, ...

[0298] In one example, terminal 101 transmits a first number of power values ​​and the numbers of the first number of time-domain sampling points to access network device 102-1, which then transmits the information to core network device 102-2, such as an LMF. The numbers of the first number of time-domain sampling points are transmitted to access network device 102-1 in the form of a bit vector. The order of the first number of power values ​​indicated in the second number of bits must match the order of the time-domain sampling point numbers indicated by the bit vector.

[0299] For example, the terminal 101 determines 8 power values ​​in the 200 time domain sampling points in descending order of power value, assuming that the corresponding time domain sampling points are numbered 1, 10, 20, 30, 40, 50, 60, and 70. Assume that the number of the time domain sampling point indicated by the first bit vector is 10, and the first to Nth bits in the second number are b - one bit is used to indicate the power value corresponding to the time domain sampling point numbered 10, the number of the time domain sampling point indicated by the second bit vector is 70, and the (Nth) bit in the second number of bits is used to indicate the power value corresponding to the time domain sampling point numbered 10. b +1) to 2N b bits are used to indicate the power value corresponding to the time domain sampling point numbered 70, and so on.

[0300] In an example, the terminal 101 sends the numbers of the first number of time domain sampling points to the access network device 102-1, and the numbers of the first number of time domain sampling points are sent in the form of bit vectors. Each bit vector indicates one of the numbers of the first number of time domain sampling points, and the indication order is not limited.

[0301] For example, terminal 101 determines 8 power values ​​in descending order of power values ​​among 200 time domain sampling points, and assumes that the corresponding time domain sampling points are numbered 1, 10, 20, 30, 40, 50, 60, and 70. Terminal 101 sends 8 bit vectors to the second device. The time domain sampling point number indicated by the first bit vector may be 50, the time domain sampling point number indicated by the second bit vector may be 1, and so on.

[0302] In some embodiments, the first data may be named nr-ChannelMeasurements, which may be used to represent PDP data or DP data. If the first data includes a first number of power values ​​and a first number of time domain sampling point numbers,

[0303] In some embodiments, if the first data includes the numbers of the first number of time-domain sampling points, the specific content of nr-ChannelMeasurements is as follows:

[0304] The above description is merely an exemplary description, and the present disclosure does not limit the content and representation of the first data.

[0305] Step S2105: Terminal 101 sends data type indication information.

[0306] In some embodiments, the terminal 101 may send data type indication information to the access network device 102-1, and the access network device 102-1 then sends the data type indication information to the core network device 102-2, such as LMF. The data type indication information is used to indicate the data type of the first data.

[0307] For example, the data type indication information is used to indicate that the data type of the first data is PDP or DP.

[0308] In some embodiments, when the terminal 101 directly reports CIR data to the access network device 102 - 1 , the data type indication information may also be used to indicate the CIR.

[0309] In some embodiments, the second device receives the data type indication information.

[0310] In some embodiments, the data type indication information may be named nr-ChannelMeasurementsType, which may be used to indicate the data type of the channel measurement, including but not limited to CIR, PDP, DP and other data types.

[0311] In step S2106, the core network device 102-2 inputs the first data into a neural network for terminal positioning, and determines a terminal positioning result based on an output result of the neural network.

[0312] In some embodiments, the core network device 102-2 may be a LMF.

[0313] In some embodiments, the LMF uses the first data as an input value of a neural network for terminal positioning to obtain an output result of the neural network, wherein the output result includes the terminal coordinates, and the output result is the terminal positioning result.

[0314] In some embodiments, the LMF uses the first data as an input value of a neural network for terminal positioning to obtain an intermediate result of the neural network, such as TOA, AOA, etc. Further, based on the intermediate result, the LMF adopts, but is not limited to, a TDOA positioning method to obtain a terminal positioning result.

[0424] In some embodiments, the information transmission method involved in the embodiments of the present disclosure may include at least one of steps S3501 to S3503. For example, step S3501 can be implemented as an independent embodiment, step S3502 can be implemented as an independent embodiment, and step S3503 can be implemented as an independent embodiment. Steps S3501 to S3503 can be implemented as independent embodiments, but are not limited thereto.

[0425] In some embodiments, steps S3501 to S3503 are optional, and one or more of these steps may be omitted or replaced in different embodiments.

[0426] In the above embodiment, after receiving the first data, the core network device can input the first data into a neural network used to perform terminal positioning, and then determine the terminal positioning result based on the output of the neural network. While ensuring positioning accuracy, this effectively reduces the data transmission overhead of positioning and improves the usability of artificial intelligence-based positioning solutions.

[0427] The above content is further illustrated below with examples.

[0428] In the embodiment of the present disclosure, the CIR data can be processed and part of the information can be retained respectively, so as to obtain power delay spectrum PDP data and delay spectrum DP data. These two types of data can also be used as inputs of the AI ​​positioning model.

[0429] PDP preserves the power and delay information of CIR data. Its data dimension is related to the number of reference signal transmitting nodes (TRPs) and the number of time domain sampling points. The PDP data for each TRP is a real number at multiple time domain sampling points. Compared to CIR, PDP data has a lower dimension.

[0430] DP retains the delay information of CIR data, and its data dimension is related to the number of reference signal sending nodes TRP and the number of time domain sampling points.

[0431] Due to the large dimension of the original CIR data, the terminal or access network equipment will cause a large data transmission overhead when reporting the complete CIR data directly to the LMF, which is not conducive to the application of AI-based positioning technology in actual communication systems; compared with CIR data, PDP and DP data have lower dimensions. Using PDP or DP data to train and apply AI positioning models can effectively reduce the reporting overhead of channel measurement data used for positioning, but the specific method of obtaining PDP and DP data based on CIR data needs to be clarified.

[0432] In addition, due to the special distribution characteristics of CIR data, in the time domain sampling point dimension, there is less data with larger amplitudes containing more information, and the data at most time domain sampling points is close to 0. Therefore, there is a large redundancy in transmitting the complete data at each time domain sampling point. Applying specific data processing methods to obtain channel measurement data with smaller data volumes can effectively reduce data reporting overhead. At the same time, data transmission between devices in actual systems needs to consider the issue of data quantization transmission. That is, the data at each sampling point location needs to be represented and transmitted using a specific number of bits, and the design of a specific data representation method also needs to be considered.

[0433] For application scenarios where terminal positioning is completed based on AI models, the AI ​​model used for positioning is deployed in LMF. The terminal or access network equipment calculates and obtains channel measurement data based on the positioning reference signal and reports it to LMF. The data is then input into the AI ​​positioning model to obtain the positioning result.

[0434] Since the terminal or access network equipment needs to report the channel measurement data used for AI positioning to the LMF, directly reporting the original channel measurement data CIR and other data will result in a large data reporting overhead. This solution first proposes a method for obtaining PDP and DP data, that is, processing the channel measurement data CIR to obtain PDP and DP data with lower data dimensions, and then proposes a specific data representation and transmission method for PDP and DP data. Under the premise of ensuring positioning accuracy, the method proposed in the present invention can significantly reduce the channel measurement data transmission overhead used for AI positioning, which is conducive to promoting the practical application of AI-based terminal positioning technology in communication systems.

[0435] Complete CIR data has a high dimensionality, but the data itself exhibits certain distribution characteristics. In the time-domain sampling point dimension, most of the data is close to zero, while a small amount of non-zero data is typically concentrated at the preceding sampling points, indicating the propagation path information of the higher-power signal received by the receiver. Generally, data with larger values ​​in the CIR plays a more important role in positioning. Therefore, this paper first proposes a method for acquiring and representing PDP data, retaining only the power and delay information at certain high-power locations in the time-domain sampling point dimension of the complete CIR data to reduce the data volume. Furthermore, experimental results show that the accuracy of AI positioning models is less sensitive to the power amplitude information in PDP data. Therefore, this paper further considers retaining only the delay information in the PDP data to obtain DP data, and proposes a method for acquiring and representing DP data. Finally, this paper summarizes the impact of the acquisition and transmission of PDP and DP data on the application of AI models in systems.

[0436] (1) In the embodiments of the present disclosure, the following PDP data acquisition, representation and transmission method is proposed:

[0437] Calculate the power value of the original CIR data at each position in the time domain sampling point dimension, that is, calculate the modulus of the complex number at each time domain sampling point position, and only retain the power value information of the strongest N positions in the time domain sampling point dimension, as well as the corresponding delay information, to obtain the PDP data. The number of data N retained in the time domain sampling point dimension can be determined according to the data transmission and positioning accuracy requirements in the actual system. N is much smaller than the number of time domain sampling points N. t .

[0438] The power value information of N positions uses N b bits for quantized transmission, N b The specific value of can be determined according to the actual system data transmission requirements;

[0439] Methods for expressing N position delay information may include:

[0440] ① Length and number of PDP time domain sampling points N t For the same bitmap, the N most powerful positions are set to 1, and the other positions are set to 0.

[0441] ②N length is The i-th bit vector represents the time domain sampling point number of the i-th strongest position.

[0442] (2) In the embodiments of the present disclosure, the following DP data acquisition, representation and transmission methods are proposed:

[0443] Calculate the power of the original CIR data at each position in the time domain sampling point dimension, that is, calculate the modulus of the complex number of each time domain sampling point position, and only retain the delay information of the strongest N positions in the data time domain sampling point dimension. The number of retained data points N can be determined according to the data transmission and positioning accuracy requirements in the actual system. For example, through comparative experiments, it is known that for the use of DP data to implement the training and application of AI positioning models, N can usually be 16 or 8. N is much smaller than the number of time domain sampling points N t .

[0444] Methods for expressing delay information of N locations may include:

[0445] Length and number of time domain sampling points of original data N t For the same bitmap, the N most powerful positions are set to 1, and the other positions are set to 0.
