[0110] In recent years, artificial intelligence (AI) technology has achieved continuous breakthroughs in multiple fields. The ongoing development of AI-based technologies 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.

[0111] In some embodiments, a research project on the application of artificial intelligence (AI) technology in wireless air interfaces is proposed. This project aims to investigate how to introduce AI technology into wireless air interfaces and explore how AI technology can assist in improving wireless air interface transmission technology.

[0112] In research geared towards 6G, 6G systems can provide AI services across more dimensions. This mainly includes the following three aspects:

[0113] AI-enabled connectivity. This means using AI to improve communication performance, such as using AI for beam management;

[0114] Computing power services. This means that the network side can provide computing power to the terminal side, such as helping the terminal to perform model training and model inference.

[0115] Ultimate AI service. This involves enhancing the network transmission pipeline to improve the user experience of AI application services.

[0116] In some embodiments, there are multiple AI-based positioning implementation methods, including AI-based direct positioning and AI-based indirect positioning. For AI-based direct positioning, there are two methods: one is that the model is deployed on the terminal side, and the terminal infers the positioning result based on the PRS; the other is that the model is deployed on the LMF side, and the terminal side sends the PRS measurement results to the LMF, which infers the positioning result based on the PRS measurement results.

[0117] In some embodiments, AI-based localization may also be referred to as machine learning (ML)-based localization, and the terms AI-based localization and ML-based localization are interchangeable.

[0118] In some embodiments, AI-based direct positioning includes the following methods:

[0119] Option 1: The AI ​​model is deployed on the terminal side. The terminal side measures the PRS sent by the base station. Based on the measurement results of the PRS and the AI ​​model, the target positioning result is directly output. The target positioning result can be the positioning coordinate information.

[0120] - Scheme 2b: The AI ​​model is deployed on the LMF side. The terminal measures the PRS sent by the base station. The terminal sends the measurement results of the PRS to the LMF. The LMF performs model inference based on the measurement results of the PRS sent by the terminal to obtain the target positioning result. The target positioning result can be the positioning coordinate information.

[0121] - Scheme 3b: The AI ​​model is deployed on the LMF side. The terminal sends SRS to the base station. The base station measures the SRS and sends the measurement results to the LMF. The LMF performs model inference based on the measurement results of the SRS sent by the base station to obtain the target positioning result. The target positioning result can be the positioning coordinate information.

[0122] In some embodiments, AI-based indirect positioning includes the following methods:

[0123] - Scheme 2a: The AI ​​model is deployed on the terminal side. The terminal side measures the PRS sent by the base station. Based on the measurement results of the PRS and the intermediate parameters of the positioning process output by the AI ​​model, such as at least one of LOS / NLOS indication and time of arrival information, the terminal sends the intermediate parameters of the positioning process to the LMF. The LMF obtains the target positioning result based on the intermediate parameters of the positioning process. The target positioning result can be the positioning coordinate information.

[0124] - Scheme 3b: The model is deployed on the base station side. The terminal sends SRS to the base station. The base station measures the SRS and outputs intermediate parameters of the positioning process based on the measurement results of the SRS and the AI ​​model, such as at least one of LOS / NLOS indication and time of arrival information. The base station sends the intermediate parameters of the positioning process to the LMF. The LMF obtains the target positioning result based on the intermediate parameters of the positioning process. The target positioning result can be positioning coordinate information.

[0125] It should be noted that the AI ​​model can be referred to as an AI function or an AI algorithm. The terms AI model and AI function or AI algorithm can be used interchangeably, and this disclosure does not impose any specific limitations on them.

[0126] In related technologies, AI-based positioning methods require terminals to have corresponding processing capabilities. For the above five AI-based positioning schemes, especially scheme 2a, how the terminal can report information on whether it has the capability to execute scheme 2a to the network device is an urgent problem to be solved.

[0127] Based on this, in this embodiment of the disclosure, the terminal sends first information to the network device. The first information indicates whether the terminal supports a first positioning method. The first positioning method involves the terminal determining intermediate positioning results based on the measurement results of the acquired Positioning Reference Signal (PRS) and an artificial intelligence (AI) model, and then sending these intermediate positioning results to the network device. These intermediate positioning results are used by the network device to determine the target positioning result. Thus, the terminal can send first information to the network device regarding whether it supports the first positioning method, allowing the network device to use an appropriate positioning method based on the terminal's supported positioning capabilities to accurately perform positioning, ensuring the accurate execution of the positioning process and guaranteeing communication quality.

[0128] Figure 2 is an interactive schematic diagram illustrating an information transmission method according to an embodiment of the present disclosure. As shown in Figure 2, the present disclosure relates to an information transmission method, which includes:

[0129] S201, the terminal sends the first information to the network device.

[0135] In some embodiments, the terminal determines to send the first information to the network device on its own, or determines to send the first information to the network device based on the instruction of the network device, or determines to send the first information to the network device based on the protocol agreement.

[0136] For example, when a terminal determines that it needs to perform a positioning process, such as when the terminal determines that it needs to determine location information or that it needs to send location information to a network device, it may send first information to the network device.

[0137] For example, when a terminal receives an instruction from a network device instructing it to send a message to the network device indicating whether it supports a first behavior mode, the terminal can determine to send the first information to the network device based on the instruction.

[0138] In some embodiments, the terminal may reuse existing signaling or messages to send first information to the network device, or send first information to the network device using new signaling or messages.

[0139] In some embodiments, the first information is a New Radio Access Technology (NR)-DL-TDOA-ProvideCapabilities (NR-DL-TDOA-ProvideCapabilities) message.

[0140] In some embodiments, the first information is the NR-DL-AOD-ProvideCapabilities message.

[0148] In some embodiments, the first information is used to indicate that the terminal supports sending intermediate location results to the network device.

[0149] In some embodiments, the first information is used to indicate that the terminal does not support sending intermediate location results to the network device.

[0150] In some embodiments, the first information is used to instruct the terminal to support sending intermediate positioning results determined based on an AI model to the network device.

[0151] In some embodiments, the first information is used to indicate that the terminal does not support sending intermediate positioning results determined based on the AI ​​model to the network device.

[0152] In some embodiments, the first information is used to instruct the terminal to support sending PRS-based measurement results and intermediate positioning results determined by the AI ​​model to the network device.

[0153] In some embodiments, the first information is used to indicate that the terminal does not support sending PRS-based measurement results and intermediate positioning results determined by the AI ​​model to the network device.

[0154] In some embodiments, intermediate positioning results include at least one of the following:

[0155] Arrival time information;

[0156] Arrival angle information;

[0157] Route guidance information.

[0158] In some embodiments, the first information is used to instruct the terminal to support sending arrival time information to the network device.

[0159] In some embodiments, the first information is used to indicate that the terminal does not support sending arrival time information to the network device.

[0160] In some embodiments, the arrival time information includes at least one of the following:

[0161] TOA;

[0162] RSTD.

[0163] In some embodiments, the first information is used to indicate that the terminal supports sending a TOA to the network device.

[0164] In some embodiments, the first information is used to indicate that the terminal does not support sending a TOA to the network device.

[0165] In some embodiments, the first information is used to indicate that the terminal supports sending RSTD to the network device.

[0166] In some embodiments, the first information is used to indicate that the terminal does not support sending RSTD to the network device.

[0170] In some embodiments, the first information is used to indicate that the terminal supports sending AOD to the network device.

[0171] In some embodiments, the first information is used to indicate that the terminal does not support sending AOD to the network device.

[0172] In some embodiments, the first information is used to indicate that the terminal supports sending path indication information to the network device.

[0173] In some embodiments, the first information is used to indicate that the terminal does not support sending path indication information to the network device.

[0174] In some embodiments, the path indication information is used to indicate at least one of the following:

[0175] NLOS path;

[0176] LOS path.

[0177] In some embodiments, the first information is used to indicate that the terminal supports sending path indication information indicating an NLOS path to the network device.

[0178] In some embodiments, the first information is used to indicate that the terminal does not support sending path indication information indicating an NLOS path to the network device.

[0179] In some embodiments, the first information is used to indicate that the terminal supports sending path indication information indicating the LOS path to the network device.

[0180] In some embodiments, the first information is used to indicate that the terminal does not support sending path indication information indicating a LOS path to the network device.

[0181] Understandably, a path can be used to represent the transmission path of a reference signal in a wireless environment. Since obstacles may exist in the wireless transmission environment, the reference signal may reach the terminal device from the network device via different paths. Therefore, paths can be divided into line-of-sight (LOS) paths and non-line-of-sight (NLOS) paths. An LOS path can refer to the transmission path where the reference signal directly reaches the terminal device from the network device. An NLOS path can refer to the transmission path where the reference signal reaches the terminal device from the network device through reflection, refraction, scattering, diffraction, etc. It is understandable that since different paths correspond to different transmission distances, the order in which the reference signal arrives at the terminal device differs under different paths, thus the time delays corresponding to different paths are different. In other words, the terminal device can distinguish between different paths based on their different time delays.

[0182] In some embodiments, the first information includes m bits, where m is a positive integer, the m bits are a first value used to indicate that the terminal supports the first positioning method, and the m bits are a second value used to indicate that the terminal does not support the first positioning method.

[0183] For example, the first information includes a bit, where a value of "1" indicates that the terminal supports the first positioning method, and a value of "0" indicates that the terminal does not support the first positioning method; or a value of "0" indicates that the terminal supports the first positioning method, and a value of "1" indicates that the terminal does not support the first positioning method.

[0184] In some embodiments, the intermediate positioning result is arrival time information, and the first information is also used to indicate whether the terminal supports downlink time difference of arrival (DL-TDOA) positioning mode.

[0185] Understandably, the downlink-time difference of arrival (DL-TDOA) positioning method involves the terminal measuring the positioning reference signal (PRS) of each cell, determining at least one of the time of arrival (TOA) and reference signal time difference (RSTD), and then sending it to the LMF.

[0186] In this embodiment of the present disclosure, the terminal sends first information to the network device. The first information is used to indicate whether the terminal supports a first positioning method. The first positioning method is that the terminal determines the arrival time information based on the obtained PRS measurement results and AI model and sends it to the network device. The arrival time information is used by the network device to determine the target positioning result. In this case, the first information is also used to indicate whether the terminal supports the downlink time difference of arrival (DL-TDOA) positioning method.

[0187] In this embodiment of the present disclosure, the terminal also supports sending second information to the network device, the second information being used to indicate whether the terminal supports downlink time difference of arrival (DL-TDOA) positioning mode.

[0189] In some embodiments, the first information includes a first indication field and a second indication field. The first indication field indicates whether the terminal supports a first positioning method, and the second indication field is used to indicate whether the terminal supports the DL-TDOA positioning method.

[0190] In some embodiments, the first information is NR-DL-TDOA-ProvideCapabilities. Specifically, nr-DL-TDOA-Mode in NR-DL-TDOA-ProvideCapabilities indicates whether the terminal supports the first positioning method and whether the terminal supports the downlink time difference of arrival (DL-TDOA) positioning method.

[0191] In some embodiments, nr-DL-TDOA-ProvideCapabilities includes m bits, where m is a positive integer. The m bits are a first value used to indicate that the terminal supports a first positioning method, and the m bits are a second value used to indicate that the terminal does not support the first positioning method.

[0192] For example, nr-DL-TDOA-ProvideCapabilities includes a bit. When the value of this bit is "1", it indicates that the terminal supports the first positioning method. When the value of this bit is "0", it indicates that the terminal does not support the first positioning method. Alternatively, when the value of this bit is "0", it indicates that the terminal supports the first positioning method. When the value of this bit is "1", it indicates that the terminal does not support the first positioning method.

[0193] In some embodiments, the intermediate positioning result is the angle of arrival information, and the first information is also used to indicate whether the terminal supports the DL-AOD positioning method.

[0194] Understandably, in the downlink-angle of departure (DL-AOD) positioning method, the terminal measures the positioning reference signal (PRS) of each cell, determines the positioning reference signal received power (PRS-RSRP), and sends it to the LMF.

[0195] In this embodiment of the present disclosure, the terminal sends first information to the network device. The first information is used to indicate whether the terminal supports a first positioning method. The first positioning method is that the terminal determines the angle of arrival information based on the obtained PRS measurement results and AI model and sends it to the network device. The angle of arrival information is used by the network device to determine the target positioning result. In this case, the first information is also used to indicate whether the terminal supports the DL-AOD positioning method.

[0196] In this embodiment of the present disclosure, the terminal also supports sending third information to the network device, the third information being used to indicate whether the terminal supports DL-AOD positioning mode.

[0197] Wherein, in the case where the first information is used to indicate whether the terminal supports the first positioning method, and the first positioning method is that the terminal determines the angle of arrival information based on the obtained PRS measurement results and AI model and sends it to the network device, and the angle of arrival information is used by the network device to determine the target positioning result, the third information can be the same as the first information.

[0198] In some embodiments, the first information includes a first indication field and a second indication field. The first indication field indicates whether the terminal supports a first positioning method, and the second indication field is used to indicate whether the terminal supports the DL-AOD positioning method.

[0199] In some embodiments, the first information is NR-DL-AOD-ProvideCapabilities. Specifically, nr-DL-AOD-Mode in NR-DL-AOD-ProvideCapabilities indicates whether the terminal supports the first positioning method and whether the terminal supports the DL-AOD positioning method.

[0200] In some embodiments, nr-DL-AOD-Mode in NR-DL-AOD-ProvideCapabilities includes m bits, where m is a positive integer. The m bits are a first value used to indicate that the terminal supports a first positioning method, and the m bits are a second value used to indicate that the terminal does not support the first positioning method.

[0201] For example, nr-DL-AOD-Mode in NR-DL-AOD-ProvideCapabilities includes a bit. When the value of this bit is "1", it indicates that the terminal supports the first positioning method. When the value of this bit is "0", it indicates that the terminal does not support the first positioning method. Alternatively, when the value of this bit is "0", it indicates that the terminal supports the first positioning method. When the value of this bit is "1", it indicates that the terminal does not support the first positioning method.

[0202] In some embodiments, the intermediate location result is path indication information, and the first information is further used to indicate at least one of the following:

[0203] Does the terminal support DL-TDOA positioning?

[0204] Does the terminal support DL-AOD positioning?

[0205] Does the terminal support MultiRTT positioning?

[0206] Understandably, in the multi-round trip time (Multi-RTT) positioning method: the terminal measures the positioning reference signal (PRS) of each cell to determine the terminal transmit-receive time difference (Rx-Tx time difference) and sends it to the LMF; each cell measures the SRS sent by the terminal to determine the gNB Rx-Tx time difference and sends the measurement result to the LMF.

[0207] In this embodiment of the present disclosure, the terminal sends first information to the network device. The first information is used to indicate whether the terminal supports a first positioning method. The first positioning method is that the terminal determines path indication information based on the obtained PRS measurement results and AI model and sends it to the network device. The path indication information is used by the network device to determine the target positioning result. In this case, the first information is also used to indicate whether the terminal supports at least one of DL-TDOA positioning method, DL-AOD positioning method, and MultiRTT positioning method.

[0208] In this embodiment of the present disclosure, the terminal also supports sending fourth information to the network device. The fourth information is used to indicate whether the terminal supports at least one of DL-TDOA positioning mode, DL-AOD positioning mode, and MultiRTT positioning mode.

[0209] Wherein, in the case where the first information is used to indicate whether the terminal supports the first positioning method, and the first positioning method is for the terminal to determine path indication information based on the obtained PRS measurement results and AI model and send it to the network device, and the path indication information is used by the network device to determine the target positioning result, the fourth information can be the same as the first information.

[0210] In some embodiments, the first information includes a first indication field and a second indication field different from the first indication field, wherein the first indication field is used to indicate at least one of the following:

[0211] Does the terminal support DL-TDOA positioning?

[0214] The second indication field is used to indicate whether the terminal supports the first positioning method.

[0215] In some embodiments, the first information is at least one of NR-DL-TDOA-ProvideCapabilities, NR-DL-AOD-ProvideCapabilities, and NR-Multi-RTT-ProvideCapabilities. Specifically, at least one of NR-DL-TDOA-ProvideCapabilities, NR-DL-AOD-ProvideCapabilities, and NR-Multi-RTT-ProvideCapabilities is used to indicate whether the terminal supports a first positioning method and whether the terminal supports at least one of DL-TDOA positioning method, DL-AOD positioning method, and MultiRTT positioning method.

[0216] In some embodiments, at least one of NR-DL-TDOA-ProvideCapabilities, NR-DL-AOD-ProvideCapabilities, and NR-Multi-RTT-ProvideCapabilities includes m bits, where m is a positive integer, the m bits are a first value used to indicate that the terminal supports a first positioning method, and the m bits are a second value used to indicate that the terminal does not support the first positioning method.

[0217] For example, at least one of NR-DL-TDOA-ProvideCapabilities, NR-DL-AOD-ProvideCapabilities, and NR-Multi-RTT-ProvideCapabilities includes a bit that, when the value of the bit is "1", indicates that the terminal supports the first positioning method, and when the value of the bit is "0", indicates that the terminal does not support the first positioning method; or, when the value of the bit is "0", it indicates that the terminal supports the first positioning method, and when the value of the bit is "1", it indicates that the terminal does not support the first positioning method.

The first positioning method is that the terminal determines path indication information based on the obtained PRS measurement results and AI model and sends it to the network device. The path indication information is used by the network device to determine the target positioning result.

[0219] In some embodiments, if a network device receives first information sent by a terminal, and the first information indicates that the terminal supports a first positioning method, and the network device receives intermediate positioning results sent by the terminal, the network device can determine the target positioning result based on the intermediate positioning results.

[0220] In some embodiments, the terminal receives the PRS sent by the base station, measures the PRS to determine the measurement result of the PRS, and further determines the intermediate positioning result based on the measurement result of the PRS and the AI ​​model, and sends the intermediate positioning result to the LMF.
