[0169] 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.

[0170] 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.

[0171] 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.

[0172] 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:

[0173] Frequency range of PRS (frequency range FR1, frequency range FR2);

[0174] PRS resource allocation bandwidth (number of physical resource blocks (PRBs));

[0175] The period of a PRS resource or resource collection;

[0176] The number of repetitions of PRS resources;

[0177] The number of symbols in PRS;

[0178] PRS comb size;

[0179] PRS spatial domain information (QCL information).

[0180] 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.

[0181] In some embodiments, in 5G NR-based positioning, SRS is a positioning reference signal used for uplink. The relevant protocol supports configuring the SRS resource set as a periodic, semi-continuous, or non-periodic time domain type. Unlike PRS resources configured by the network-side positioning server (or LMF), the SRS resource set and the configuration of SRS resources are completely controlled by the base station.

[0182] The embodiments of the present disclosure provide an on-demand SRS-Pos mechanism to enable a terminal to indicate an SRS-Pos transmission period or time length that it can support, thereby preventing the terminal from sending SRS for positioning too frequently and reducing terminal power consumption.

[0322] In order to better understand the embodiments of the present disclosure, the present disclosure is further described below through some exemplary embodiments:

[0323] Example 1

[0324] In some embodiments, the UE indicates relevant information of the SRS-Pos configuration (corresponding to the first SRS-Pos configuration parameter) that it can support in the request information sent to the network side (base station, positioning server or LMF).

[0325] In some embodiments, the reporting information of the terminal includes the SRS-Pos configuration expected by the terminal (corresponding to the second SRS-Pos configuration parameter).

[0326] In some embodiments, the type corresponding to the SRS-Pos configuration parameter supported by the terminal may be indicated to be one or more of the following three types, namely, periodic, semi-persistent or aperiodic.

[0327] In some embodiments, the terminal can only indicate the following combinations:

[0328] {Aperiodic};

[0329] {Aperiodic,semi-persistent};

[0330] {Aperiodic, semi-persistent, periodic}.

[0331] For example, the signaling is:

[0332] In some embodiments, for the periodic and semi-persistent type SRS-Pos resource set or resource configuration indicated by the terminal, the requested period and / or offset may be further indicated. For example, the signaling is:

[0333] In some embodiments, for a semi-persistent or periodic type application, it may further indicate UL-SRS-StartTime-and-Duration to indicate the expected or applied SRS start time and offset.
