Referring to FIG. 2, FIG. 2 is a schematic flowchart of a method for reporting a timing error according to some embodiments of the present disclosure, and the method is performed by an LMF network element. As shown in FIG. 2, the method may include, but is not limited to, the following steps.

In step 21, first indication information transmitted by a transmission end is received, where the first indication information is used for indicating timing error group information of the transmission end, and the transmission end is a terminal device or a transmitting reception point.

Generally, in a communication system, a time delay may exist in in the process from generating a signal by a baseband processor to transmitting the signal by an antenna radio frequency port. Correspondingly, a time delay may also exist in the process from receiving a signal by an antenna radio frequency port to reaching a baseband processor by the signal. The above time delay is commonly referred to as timing error group (TEG). In the positioning process, the above-mentioned time delay can affect the positioning performance. Therefore, how to improve the positioning accuracy becomes a problem to be solved urgently.

In a related positioning method, for example, in an observed time difference of arrival (OTDOA) method, the terminal device is positioned according to the time difference of the signal propagation between three base stations and the terminal device. Among them, the time difference of the signal propagation between the base station and the terminal device includes a timing error corresponding to the terminal device and a timing error corresponding to the base station. In the present disclosure, the terminal device or the transmission and reception point (TRP) may transmit its corresponding TEG information to the LMF network element, so that the LMF network element can remove the influence caused by the TEG information in the process of positioning the terminal device, so as to improve the accuracy and precision of positioning.

In the embodiments of the present disclosure, the LMF network element may receive the timing error group (TEG) information transmitted by the terminal device, so as to obtain the TEG information of the terminal device. Then, the LMF network element may position the terminal device according to the TEG information of the terminal device, thus reducing the positioning error as much as possible and improving the positioning accuracy. Alternatively, the LMF network element may also receive the TEG information of the transmission and reception point (TRP), so as to obtain the TEG information of the TRP. Then, the LMF network element may position the terminal device according to the TEG information of the TRP, thus reducing the positioning error as much as possible and improving the positioning accuracy.

In some embodiments, the TEG information may be a TEG value, or may be a TEG identification; Alternatively, it may also be a TEG value and a TEG identification, or the like, which is not limited in the present disclosure.

Among them, the style or presentation form of the TEG identification may be any form agreed upon in the protocol; for example, it may be TEG_0, TEG_1, or the like, which is not limited in the present disclosure.

By implementing the embodiments of the present disclosure, the LMF network element may receive the first indication information transmitted by the terminal device or the TRP, so as to obtain the TEG information of the terminal device or the TEG information of the TRP; and then, the LMF network element may position the terminal device based on the TEG information of the terminal device or the TEG information of the TRP, thus reducing the positioning error as much as possible and improving the positioning accuracy.

Referring to FIG. 3, FIG. 3 is a schematic flowchart of a method for reporting a timing error according to some embodiments of the present disclosure, and the method is performed by an LMF network element. As shown in FIG. 3, the method may include, but is not limited to, the following steps.

In step 31, second indication information is transmitted, where the second indication information is used for indicating a granularity factor corresponding to the TEG information.

Among them, The LMF network element may transmit the second indication information to the terminal device, so that the terminal device may determine corresponding TEG information according to the received granularity factor; or, the LMF network element may also transmit the second indication information to the TRP, so that the TRP may determine corresponding TEG information according to the received granularity factor.

In some embodiments, the LMF network element may determine a granularity factor corresponding to the TEG information according to the current positioning accuracy.

For example, the higher the current positioning accuracy, the smaller the granularity factor corresponding to the TEG information; and, the lower the current positioning accuracy, the greater the granularity factor corresponding to the TEG information.

Alternatively, the corresponding relationship between the positioning accuracy and the granularity factor may also be agreed upon in the protocol. Therefore, the LMF network element may determine the granularity factor corresponding to the TEG information according to the current positioning accuracy and the corresponding relationship between the positioning accuracy and the granularity factor.

It should be noted that the above examples are illustrative and cannot be used as a limitation on the manner for determining the granularity factor corresponding to the TEG information in the embodiments of the present disclosure.

In some embodiments, the LMF network element may also determine the granularity factor corresponding to the TEG information according to a value range of the granularity factor corresponding to each subcarrier spacing (SCS).

For example, the value range of the granularity factor corresponding to each subcarrier spacing (SCS) may be agreed upon in the protocol. Therefore, the LMF network element may determine, according to the current subcarrier spacing, the value range of the granularity factor corresponding to the current subcarrier spacing, and select any numerical value from the value range of the granularity factor as the value of the granularity factor, which is not limited in the present disclosure.

In some embodiments, the second indication information may be request location information.

Therefore, in the embodiments of the present disclosure, the LMF network element may indicate the granularity factor corresponding to the TEG information to the terminal device or the TRP through transmitting the request location information.

For example, it may be agreed upon in the protocol that a specific bit is added to the request location information, and the granularity factor is represented by a value of the specific bit. Therefore, after receiving the request location information, the terminal device or the TRP may determine the corresponding granularity factor or the like according to the value of the specific bit, which is not limited in the present disclosure.

In step 32, first indication information transmitted by a transmission end is received, where the first indication information is used for indicating TEG information of the transmission end, and the transmission end is a terminal device or a TRP.

Among them, the resource information of the DL PRS may be time domain resource information of the DL PRS, or may also be frequency domain resource information of the DL PRS, or may also be time domain and frequency domain resource information of the DL PRS, or the like, which is not limited in the present disclosure.

In addition, the RSTD measurement information may include a timing error of a transmission end, or may also include a timing error of a reception end, or the like, which is not limited in the present disclosure.

In some embodiments, the LMF network element may obtain TEG information of the TRP and resource information of the DL PRS according to the received first indication information transmitted by the TRP, and position the terminal device according to the TEG information and the resource information of the DL PRS, thus reducing the positioning error as much as possible and improving the positioning accuracy.

Alternatively, the LMF network element may also obtain TEG information and RSTD measurement information of the terminal device according to the received first indication information transmitted by the terminal device, process the RSTD measurement information according to the TEG information, and then position the terminal device, thus reducing the positioning error as much as possible and improving the positioning accuracy.

In some embodiments, the TEG information may be a TEG value and/or a TEG identification, the specific content and implementation manner of which may refer to the description of other embodiments of the present disclosure, and details are not described here again.

By implementing the embodiments of the present disclosure, the LMF network element may transmit the second indication information so as to indicate the granularity factor corresponding to the TEG information to the transmission end, and then may obtain the TEG information of the transmission end according to the received first indication information transmitted by the transmission end, and then may position the terminal device according to the TEG information of the transmission end, thus reducing the positioning error as much as possible and improving the positioning accuracy.

Referring to FIG. 4, FIG. 4 is a schematic flowchart of a method for reporting a timing error according to some embodiments of the present disclosure, and the method is performed by an LMF network element. As shown in FIG. 4, the method may include, but is not limited to, the following steps.

In step 41, third indication information is transmitted to the terminal device, where the third indication information is used for indicating the resource information of the DL PRS and the TEG information of the LMF.

In the embodiments of the present disclosure, the LMF network element may transmit the third indication information to the terminal device, so that the terminal device may obtain the resource information of the DL PRS and the TEG information of the LMF, and perform positioning according to the resource information of the DL PRS and the TEG information of the LMF, thus reducing the positioning error and improving the positioning accuracy.

By implementing the embodiments of the present disclosure, the LMF network element may indicate the resource information of the DL PRS and the TEG information of the LMF to the terminal device, so that the terminal device performs positioning according to the resource information of the DL PRS and the TEG information of the LME Therefore, the influence of TEG information on positioning is avoided, thus reducing the positioning error and improving the positioning accuracy.

In some embodiments of the present disclosure, the TEG information may be a TEG value and/or a TEG identification, the specific content and implementation manner of which may refer to the description of other embodiments of the present disclosure, and details are not described here again.

For example, Tc is a time unit, the value range of TEG may be [−x, y] *Tc, and the size of the granularity may be 2 k*Tc. For example, the value of k is −1, and the mapping relationship between the identification and the value of TEG may be as shown in Table 1 below.

For example, in the case that the granularity factor is −1, if the LMF network element determines that the TEG value satisfies −x≤TEG<−x+0.5, the LMF network element may determine the current TEG identification as TEG_1. Then, the LMF network element may transmit third indication information to the terminal device, so that the terminal device may obtain the resource information of the DL PRS and the TEG identification of the LMF network element as TEG_1. Therefore, when performing positioning, the terminal device may remove the influence of the TEG of the LMF network element on the positioning result, thus reducing the positioning error as much as possible and improving the positioning accuracy.

It should be noted that the above examples are illustrative, and cannot be used as a limitation on the value of the granularity factor, the value and the identification of the TEG, or the like, in the embodiments of the present disclosure.

Therefore, the terminal device can determine the value range of the granularity factor corresponding to the terminal device according to the current subcarrier spacing, and then select any numerical value as the value of the granularity factor from the range of the granularity factor value, which is not limited in the present disclosure.
