[0035] Based on this, in order to facilitate the understanding of the technical solution provided by this application, the relevant technologies involved in this application are introduced below, and the content is as follows.

[0036] like Figure 1b As shown, parameter t represents the time-varying channel. The time-domain channel impulse response c(τ,t) contains N(t) propagation paths (or paths) at time t. Each propagation path is determined by three parameters: amplitude information α n (t), phase information Delay information τ n (t), which respectively describe: the propagation of the signal from the transmitter to the receiver, in each path (such as Figure 1bThe amplitude attenuation, phase change and propagation delay experienced on the paths 0, 1 and 2 shown in FIG. 1 are different. In this regard, in a wireless communication system, the paths can be accurately modeled and estimated to perform signal recovery / correction, device positioning, etc.

[0037] Among them, taking the wireless communication system based on orthogonal frequency division multiplex (OFDM) as an example, Figure 1c As shown, in order to estimate the time domain channel impulse response, the receiving end can sample the pilot signal transmitted by the transmitting end in the time domain, and then transform the time domain signal to the frequency domain through Fast Fourier Transform (FFT) to obtain the pilot signal in the frequency domain. Since the pilot sequence is known at the receiving end, the channel frequency response can be estimated. Among them, the channel frequency response describes the changes in amplitude and phase experienced by the wireless signal on different subcarriers. Finally, the channel frequency response is transformed by Inverse Fast Fourier Transform (IFFT) to obtain the time domain channel impulse response.

[0038] In fact, the time domain channel impulse response estimated by the above process has errors. A typical case is that the estimated time domain channel impulse response will also detect "false" propagation paths near the taps corresponding to the real propagation paths. That is to say, in actual situations, the amplitude of the channel impulse response on these taps should be 0. Due to some non-ideal factors in hardware implementation, the propagation paths are detected on these taps. Non-ideal factors include the estimation error of the channel frequency response, the inconsistency between the number of channel frequency sampling points and the length of the IFFT transformation interval, etc. For the second point, the following is an example. For example, the bandwidth is 100MHz, the subcarrier spacing is 30kHz, and it is assumed that the pilot covers the entire bandwidth with a total of 3276 subcarriers. The dimension of the channel frequency response estimated by the above process is 3276*1, that is, the number of channel frequency sampling points is 3276; in order to facilitate hardware implementation, the number of FFT and IFFT points is generally set to an integer power of 2 and is greater than the number of channel frequency sampling points, such as 4096 IFFT points.

[0039] Based on this, the technical solution provided by the embodiments of the present application is described in detail below through some embodiments and their application scenarios in combination with the accompanying drawings.

[0040] like Figure 2 As shown, it is a flowchart of a positioning method 200 provided by an exemplary embodiment of the present application. The method 200 can be, but is not limited to, executed by a first device, and can be specifically executed by hardware and / or software installed in the first device. In this embodiment, the method 200 can at least include the following steps.

[0041] S210: The first device obtains first information according to the target rule.

[0042] Among them, in this embodiment, the first device can measure the target reference signal (such as the positioning reference signal (Positioning Reference Signal, PRS) during downlink measurement, the sounding reference signal (Sounding Reference Signal, SRS) during uplink measurement, etc.), and then obtain the first information (such as the path information of the channel used for the target reference signal measurement or the tap symbol information of the channel) according to the measurement result and the target rule for device positioning. Among them, for the aforementioned target reference signal, when downlink positioning is performed and the first device is a terminal, the target reference signal can be a PRS sent by a network side device; when uplink positioning is performed and the first device is a network side device, the target reference signal can be an SRS sent by a terminal, and there is no limitation here.

[0043] It is worth noting that the purpose of acquiring the first information based on the target rule in the present application is: in order to align the first information used for device positioning with the second information used to train the positioning model when performing device positioning based on the first information and the positioning model, such as making the first information used for device positioning related to the second information used to train the positioning model (also referred to as a model training set), such as the first information and the second information have the same acquisition method, acquisition rule or processing method, etc., so that when the device is positioned, the type of the first information used by the positioning model is consistent / matched with the type of the second information, thereby greatly improving the accuracy of the positioning result of the device positioning based on the first information and the positioning model, and avoiding the problem of inconsistency in the path information selection method of the first information and the model training set due to the use of a conventional (legacy) method to obtain the first information (such as channel path information or channel tap symbol information) when performing device positioning in the related technology.

[0044] In this case, it can be understood that when the first device obtains the first information according to the target rule, the target rule can be configured with a method for obtaining the first information, and the method for obtaining the first information is related to the method for obtaining the second information, and the second information is used to train a positioning model related to the positioning of the device to ensure that the first information used for device positioning is related to the second information used to train the positioning model (also referred to as a model training set). Optionally, in this embodiment, depending on the positioning scenario, the target rule can be implemented by protocol agreement, high-level configuration, or network-side configuration, which is not limited here.

[0045] In addition, the aforementioned path information (or propagation path information) of the channel refers to the multipath information estimated by a correlation algorithm based on the channel frequency response or the time domain channel impulse response. In this embodiment, the path information of the channel includes at least one of path delay information, path power information, and path phase information.

[0046] And, the tap symbol information (or symbol information) of the channel refers to the receiver processing the channel frequency response according to a predetermined method or rule to obtain the time domain channel impulse response, and then the symbol information on each tap according to the time domain channel impulse response. In this embodiment, the tap symbol information of the channel includes at least one of tap symbol delay information, tap symbol power information, and tap symbol phase information.

[0047] As for the aforementioned positioning model, the positioning model can be an artificial intelligence (AI) model. It is worth noting that the AI ​​model mentioned in the subsequent application can also be called an AI unit, an AI module, a machine learning (ML) model, an ML unit, an AI structure, an AI function, an AI feature, a machine learning model, a neural network, a neural network function, a neural network function, a decision tree, a support vector machine, a Bayesian classifier, etc., or the AI ​​model can also refer to a processing unit that can implement specific algorithms, formulas, processing procedures, capabilities, etc. related to AI, or the AI ​​model can be a processing method, algorithm, function, module or unit for a specific data set, or the AI ​​model can be a processing method, algorithm, function, module or unit running on AI / ML related hardware such as GPU, NPU, TPU, ASIC, etc., and the present invention does not specifically limit this. Optionally, the specific data set includes the input or output of the AI ​​model.

[0048] Furthermore, the identifier of the AI ​​model may be an AI structure identifier, an AI algorithm identifier, or an identifier of a specific data set associated with the AI ​​model, or an identifier of a specific scenario, environment, channel feature, or device related to the AI / ML, or an identifier of a function, feature, capability, or module related to the AI / ML, which is not specifically limited herein.

[0049] In this embodiment, the first device obtains first information used for device positioning, and the method for obtaining the first information is related to the method for obtaining the second information, and the second information is used to train a positioning model related to the positioning of the device. Therefore, when positioning the device, the first information adopted by the positioning model related to the device positioning can be related to the second information used to train the positioning model, so as to greatly improve the accuracy of the positioning result of the device positioning based on the positioning model and the first information.

[0050] like Figure 3aAs shown, it is a flowchart of a positioning method 300 provided by an exemplary embodiment of the present application. The method 300 can be, but is not limited to, executed by a first device, and can be specifically executed by hardware and / or software installed in the first device. In this embodiment, the method 300 can at least include the following steps.

[0051] S310: The first device obtains first information according to a target rule.

[0052] Among them, the first information is used for device positioning, the target rule configures the method for obtaining the first information, the method for obtaining the first information is related to the method for obtaining the second information, and the second information is used to train a positioning model related to the device positioning.

[0053] It can be understood that in addition to referring to the relevant description in method embodiment 200, the implementation process of S310, in one implementation method, the first information can be determined based on T TRPs or channel measurement information corresponding to the cell (such as channel path information or tap symbol information, etc.), and the channel measurement information can be measured based on the target reference signal, and T is an integer greater than or equal to 1.

[0054] In another possible implementation, the method in which the first device obtains the first information according to the target rule may include at least one of the following (11)-(14).

[0055] (11) Select N (N is an integer greater than or equal to 1) paths from the measured multiple paths (i.e., paths or propagation paths) according to the delay information, and use the relevant information of the N paths as the path information of the channel. For example, the first device may select N paths from the measured multiple paths according to the delay information, such as sorting the multiple paths according to the delay size, and selecting the top N paths, or the first device may first use the first path in terms of delay as the first path among the N paths, and then select N-1 paths from the multiple paths according to the power information, such as the N-1 path with the largest power, etc., and the N-1 paths do not include the first path.

[0056] It can be understood that the "first path in terms of delay" mentioned in this application can be understood as the path with the smallest delay among multiple paths. Among them, after the first device obtains the information of N paths, if it needs to send the information of the N paths to other devices, it can send the information of the N paths at the same time, or it can send the first path information and the N-1 path information separately. Correspondingly, if it is necessary to indicate the method of obtaining the information of the N paths to other devices, it can indicate the method of obtaining the information of the N paths at the same time, or it can indicate the method of obtaining the first path information and the method of obtaining the N-1 path information separately, and there is no limitation here.

[0057] (12) Select N (N is an integer greater than or equal to 1) paths from the measured multiple paths according to power information (such as reference signal received path power (RSRPP)), and use the relevant information of the N paths as the path information of the channel. Figure 3b As shown, assuming that the symbols on the taps corresponding to the peak values ​​of the time domain channel impulse response can be used as path information, such as path 1, path 2, path 3, and path 4, and N is 2, then the first two propagation paths with the strongest power can be selected, such as path 1 and path 2; for another example, the multipath information can be estimated based on the channel frequency domain response and the Multiple Signal Classification (MUSIC) algorithm, and then the first N propagation paths with the strongest power can be selected based on the estimation results. This embodiment does not impose any restrictions on this.

[0058] (13) Selecting M (M is an integer greater than or equal to 1) tap symbols from the measured multiple tap symbols according to the delay information, and using the relevant information of the M tap symbols as the tap symbol information of the channel. For example, the first device may select M tap symbols from the measured multiple tap symbols according to the delay information; or, the first device uses the tap symbol corresponding to the first path on the delay as the first tap symbol among the M tap symbols, and selects M-1 tap symbols from the multiple tap symbols according to the power information, and the M-1 tap symbols do not include the first tap symbol.

[0059] (14) Select M (M is an integer greater than or equal to 1) tap symbols from the measured multiple tap symbols according to the power information, and use the relevant information of the M tap symbols as the tap symbol information of the channel, for example Figure 3c As shown, assuming that 4 tap symbols are measured and M is 2, then the first two tap symbols with the largest power among the 4 tap symbols, namely tap symbol 3 and tap symbol 4, can be directly selected according to the time domain channel impulse response.

[0060] In this case, as a possible implementation method, in addition to obtaining the target rule according to the method agreed upon in the protocol, the method for obtaining the target rule may also include at least one of the following methods 1 and 2 depending on different positioning scenarios.

[0061] Mode 1: When the first information is used for the second device to perform device positioning, the first device receives first indication information sent by the second device, where the first indication information is used to indicate or include the target rule.

[0062] That is, a positioning model for device positioning is deployed in the second device, and the first device is used to obtain the first information and send the first information to the second device, so that the second device can use the first information as input to the positioning model to perform device positioning. Among them, since the method of obtaining the first information is related to the second information used for positioning model training (also referred to as a training data set for positioning model training) (e.g., the two are consistent), the accuracy of the device positioning result obtained by the second device based on the first information and the positioning model can be greatly improved.

[0063] Optionally, when sending the first information to the second device, the first device may also send third information to the second device to indicate a method for obtaining the first information sent by the first device. Thus, on the one hand, when the second device performs device positioning based on the first information and the positioning model, it can further verify whether the method for obtaining the first information is related to the method for obtaining the second information based on the third information to ensure the accuracy of the positioning result; on the other hand, for a second device (such as the network side) configured with multiple positioning models (applicable to different configurations), it also helps the second device to select a suitable model to locate the first device (such as a terminal).

[0064] In a possible implementation, the first device may also send first capability information to the second device, so that the method for obtaining the first information indicated by the second device to the first device matches the capability of the first device, thereby ensuring the reliability of obtaining the first information.

[0065] Optionally, the first capability information may include or indicate at least one of the following (21)-(22).

[0066] (21) A method for obtaining the first information supported by the first device.

[0067] The method for obtaining the first information supported by the first device may include but is not limited to those described in (11)-(14) above, which will not be repeated here.

[0068] (21) The size of the IFFT window supported by the first device, the size of the IFFT window being related to the acquisition of the first information, such as the IFFT transform window being used by the first device to transform a frequency domain channel impulse response into a time domain channel impulse response, and the time domain channel impulse response being used to determine the first information.

[0069] In this case, after receiving the first capability information, the second device may send first indication information to the first device to indicate the target rule, and the second device may also send second indication information to the first device to indicate or include the size of the IFFT transform window, the IFFT transform window being used by the first device to transform the frequency domain channel impulse response to the time domain channel impulse response, the time domain channel impulse response being used to determine the first information. Then, after receiving the second indication information, the first device may acquire the first information according to the size of the IFFT transform window indicated by the second indication information and the first indication information, so as to ensure the high reliability of the acquired first information.

[0070] Optionally, in this embodiment, the size of the IFFT transform window is one of the following (31)-(32).

[0071] (31) The size of the IFFT window is equal to the number of subcarriers in the channel frequency response.

[0072] (32) The size of the IFFT window is greater than the number of subcarriers of the channel frequency response and is an integer power of 2.

[0073] The channel frequency response described in (31)-(32) above can be estimated based on the measured target reference signal, and the target reference signal can be but is not limited to a downlink PRS or an uplink SRS, etc.

[0074] In addition, in addition to the aforementioned indication of the size of the IFFT transform window through the second indication information, in one implementation method, the size of the IFFT transform window can also be indicated by implicit indication. For example, the second device (such as a network side device) can implicitly indicate the size of the IFFT transform window while indicating other parameters (such as relevant parameters of the positioning model, target rules, etc.) to save network overhead. This embodiment does not make specific restrictions here.

[0075] It is worth noting that in this mode 1, when the first device is a terminal device, the second device used for device positioning can be a terminal device or an access network device, and the positioning model deployed in the second device can be implemented by protocol agreement or core network equipment (such as LMF, etc.) or third-party server provision. It can be understood that if the second device is an access network device, then the second device performs terminal positioning on the first device based on the positioning model.

[0076] When the first device is an access network device, the second device used for device positioning can be a core network device (such as LMF, etc.) or a third-party server, etc., and the positioning model deployed in the second device can be implemented by protocol agreement, etc., and there is no restriction here.

[0077] Mode 2: When the first information is used for the first device to perform device positioning and the positioning model is provided by a third device, second indication information sent by the third device is received, where the second indication information is used to indicate or include the target rule.

[0078] That is to say, compared with method 1, in method 2, the first information is acquired by the first device, and the device is positioned based on the first information and the positioning model, while the positioning model deployed in the first device can be agreed upon by the protocol or provided by a third device. Therefore, the third device can indicate the target rule to the first device, so that before the first device acquires the first information, it can determine the method for acquiring the first information according to the target rule sent by the third device, thereby ensuring that the method for acquiring the first information is related to (such as consistent with) the method for acquiring the second information used for training the positioning model, thereby ensuring the accuracy of the positioning result of the device positioning based on the acquired first information and the positioning model.

[0079] Based on this, in one implementation, the first device may also send second capability information to the third device, where the second capability information is used to indicate that the first device supports the positioning function associated with the target rule, thereby enabling the third device to provide the first device with the positioning model it supports or the method for obtaining the first information (i.e., the target rule) as much as possible, so as to further ensure the accuracy of the positioning result.

[0080] Optionally, the second capability information includes or indicates at least one of the following (41)-(42).

[0081] (41) An identifier of at least one positioning function supported by the first device.

[0082] (42) The first device supports direct positioning based on a positioning model. Here, “direct positioning based on a positioning model” can be understood as that after the first device inputs the first information into the positioning model, the positioning result can be directly obtained from the output of the positioning model, such as position coordinates, line of sight (LOS) path arrival time (TOA), LOS indication, non-line of sight (NLOS) indication, etc. The positioning model can be, but is not limited to, an AI model.

[0083] (43) The first device supports auxiliary positioning based on a positioning model. The auxiliary positioning based on a positioning model can be understood as that after the first information is input into the positioning model, the output of the positioning model is an intermediate feature quantity, and the first device needs to further estimate the device position based on the intermediate feature quantity to achieve device positioning. The positioning model can be, but is not limited to, an AI model.

[0084] (44) The type of input or output information of the positioning model.

[0085] It is worth noting that, in Mode 2, when the first device is a terminal device, the third device that provides the positioning model to the first device may be a terminal device or an access network device.

[0086] When the first device is an access network device, the third device that provides the positioning model to the first device may be a core network device (such as LMF, etc.) or a third-party server.

[0087] It is worth noting that in addition to directly carrying the target rule in the first indication information and the second indication information, in one implementation method, multiple target rules corresponding to different positioning models are pre-configured in the first device through protocol agreement, etc., and the first indication information or the second indication information can be used to instruct the first device to acquire the first information based on one of the multiple target rules. That is, the first indication information can carry identification information of the target rule, etc., thereby saving bandwidth resources and improving communication efficiency.
