[0159] AI technology has achieved breakthroughs and progress in various research fields, finding widespread application in education, transportation, home appliances, healthcare, retail, and other areas. AI-based enhancements to wireless limited communications are also a key research area within the communications industry. Wireless communication networks are characterized by complex channels, low signal-to-noise ratios, and limited transmission rates. Artificial intelligence can improve the transmission efficiency and reliability of wireless signals through data analysis and model training, thereby enhancing the quality of wireless communications. RAN1 has initiated a research project on enhancing the wireless air interface with AI technology. This project aims to introduce AI models into wireless communication networks to enhance specific use cases, such as channel state information (CSI) reporting, beam management, and positioning. This project aims to reduce network overhead and enhance performance. Regarding positioning enhancements, the project aims to enhance positioning accuracy through AI models trained on large amounts of data, including both AI-directed positioning and AI-assisted positioning.

[0160] Please refer to Figure 1b, where case 1 shows: UE-side model positioning based on UE, which can be direct AI / machine learning (ML) or AI / ML-assisted positioning, can be the UE directly sending the positioning result to the positioning management function (LMF) after positioning.

[0161] Case 2a shows: UE-assisted / LMF-based UE-side model positioning, which can be AI / ML-assisted positioning, that is, the UE assists the LMF in positioning, and what is reported to the LMF can be intermediate results.

[0162] Case 2b shows: UE-assisted / LMF-based LMF-side model positioning, which can be direct AI / ML positioning. The UE reports PRS-based measurement results to the LMF.

[0163] Case 3a shows: NG-RAN node assisted positioning based on the gNB side model, which can be AI / ML assisted positioning. After assisted positioning, the base station will send the intermediate results to the LMF.

[0164] Case 3b shows: LMF side model NG-RAN node assisted positioning, which can be direct AI / ML positioning, and the base station reports the PRS-based measurement results to the LMF.

[0165] In some embodiments, in positioning based on 5G New Radio (NR), PRS is used for downlink positioning reference signals (such as Downlink Time Difference Of Arrival (DL-TDOA), DL-DOA or multi-station round-trip time (multi-RTT), etc.). In order to avoid the air interface overhead caused by excessive occupation of time and frequency resources due to frequent sending of PRS, and at the same time make the PRS configured by the network side to the terminal more adaptable to positioning services, especially the needs of positioning services initiated by the terminal, Release 17 introduces an on-demand PRS request and configuration mechanism based on terminal request. The principle is that the terminal can send the required PRS configuration to the network side, and the network side can configure it according to the needs of the terminal to meet the terminal positioning requirements. Possible configuration parameters include at least one of the following:

[0166] Frequency range of PRS (frequency range FR1, frequency range FR2);

[0167] PRS resource allocation bandwidth (number of physical resource blocks (PRBs));

[0168] The period of a PRS resource or resource collection;

[0169] The number of repetitions of PRS resources;

[0170] The number of symbols in PRS;

[0171] PRS comb size;

[0172] PRS spatial domain information (QCL information).

[0173] In some embodiments, for AI-enhanced positioning mechanisms, especially when the AI ​​model is deployed on the terminal and the terminal performs the position solution, the related PRS request mechanism may not be able to request a large number of PRS samples corresponding to a sufficient variety of different configurations. Therefore, it is possible to consider enhancing the existing on-demand PRS mechanism to meet the needs of training, monitoring, and / or inference for the AI ​​model.

[0312] In order to better understand the embodiments of the present disclosure, the present disclosure is further described below through some exemplary embodiments:

[0313] Example 1

[0314] In some embodiments, the UE requests multiple PRS configurations (corresponding to the first PRS configuration information) for data training in a request message sent to the network side (positioning server or LMF) at one time.

[0315] In some embodiments, the reporting information of the terminal includes a plurality of (corresponding to one group) pieces of PRS configuration information (corresponding to the second PRS configuration information).

[0316] In some embodiments, multiple groups of PRS configuration information may be distinguished by different Start times and Durations.

[0317] In some embodiments, the signaling for sending the request information may be signaling specifically for applying for PRS configuration information for AI data training, rather than signaling for PRS configuration for a traditional NR positioning method. For example, the following underlined portion corresponds:

[0318] In some embodiments, in multiple pieces of PRS configuration information (corresponding to one group) requested by the UE, the times corresponding to the multiple DL-PRS-StartTime-and-Durations do not overlap;

[0319] In some embodiments, when the network side (such as LMF) performs corresponding PRS configuration on the terminal, it is also necessary to add corresponding DL-PRS-StartTime-and-Duration information on the basis of traditional indication / configuration information. The reason for this indication is that the network side cannot send PRS according to the start time and length indicated by the UE due to network load considerations. Therefore, the network side needs to further indicate the effective time of the PRS configuration, that is, the network side will send the start time and time length of the PRS according to the indicated configuration. Correspondingly, the network side can also indicate multiple sets of configurations for the terminal for multiple StartTime-and-Durations in a non-overlapping manner. At the same time, the configuration information here can also be a dedicated configuration for AI data training. For example: corresponding to the following underlined part:

[0320] In some embodiments, the terminal may also apply for a PRS configuration for different TRPs or TRP groups. This method can be used to apply for a specific PRS configuration for a specific TRP when the terminal has certain prior information about the training sequence: the specific IE information is as follows, that is, applying for a corresponding PRS configuration for a series of TRPs {TRP index #0, TRP index #1, ...}. Exemplarily, it corresponds to the following underlined part:

[0321] In some embodiments, corresponding TRP indication information may also be added to the configuration information (assistanceData) to indicate which TRP or TRPs this configuration is performed for.

[0322] In some embodiments, the above-mentioned methods for applying for PRS configuration for different TRPs (or TRP groups) and different start times and time lengths can be implemented separately or jointly.

[0323] In some embodiments, the corresponding PRS configuration information in the corresponding Start time and Duration satisfies a first condition, which may be:

[0324] The positioning accuracy in meters is greater than the threshold;

[0325] Quality is greater than the threshold;

[0326] and / or the processing delay is less than a threshold.

[0327] In some embodiments, a request may be made for PRS transmission of a corresponding TRP or TRP group, provided that the corresponding training result satisfies the first threshold.

[0328] In some embodiments, the signaling for sending the PRS configuration information may be: corresponding to the following underlined portion:

[0329] In the embodiments of the present disclosure, some or all of the steps and their optional implementations may be arbitrarily combined with some or all of the steps in other embodiments, or may be arbitrarily combined with the optional implementations of other embodiments.

[0330] The embodiments of the present disclosure further provide an apparatus for implementing any of the above methods. For example, an apparatus is provided, comprising units or modules for implementing each step performed by a terminal in any of the above methods. For another example, another apparatus is provided, comprising units or modules for implementing each step performed by a network device (e.g., an access network device, a core network function node, a core network device, etc.) in any of the above methods.

[0331] It should be understood that the division of the various units or modules in the above device is merely a division of logical functions. In actual implementation, they may be fully or partially integrated into a physical entity, or they may be physically separated. In addition, the units or modules in the device may be implemented in the form of a processor calling software: for example, the device includes a processor, the processor is connected to a memory, and the memory stores instructions.
