Description
Technical Field
The present application relates to the field of communications technologies, and in particular, to an information indicating method and apparatus, a terminal device, a network device, and a storage medium.
Background
In the existing positioning method, a Multi-RTT positioning method is an important positioning method, and the operating principle of the Multi-RTT positioning method is as follows: and the UE reports the acquired UE transceiving time difference to the LMF, each TRP also provides the acquired gNB transceiving time difference to the LMF, and the LMF obtains the distance between the UE and each TRP by using the UE transceiving time difference and the gNB transceiving time difference. Then, other known information (e.g., the geographical coordinates of the TRP) is added to calculate the location of the UE.
In order to complete the measurement of the UE transceiving time difference or the gNB transceiving difference, the TRP needs to transmit DL-PRS and the UE needs to transmit SRS-Pos, and the UE or the gNB can complete the measurement of the related measurement quantity based on the DL-PRS and the SRS-Pos. In the conventional protocol, when a positioning time measurement quantity such as a UE transmission/reception time difference or a gNB transmission/reception time difference is calculated, the protocol assumes that time measurement is performed at an Antenna Connector (Antenna Connector) position, but actually, a time measurement position of a signal is in a baseband unit, so that a time measurement error exists, which is referred to as a transmission/reception timing error, for both signal transmission and signal reception. The existence of the receiving and transmitting timing errors may cause inaccurate measurement results of all time-based positioning measurement quantities including the UE receiving and transmitting time difference and the gNB receiving and transmitting time difference, thereby affecting the final positioning accuracy.

Detailed Description
The technical solutions in the embodiments of the present application will be described clearly and completely with reference to the drawings in the embodiments of the present application, and it should be understood that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
It should be noted that, as shown in fig. 1, the operating principle of the round trip time positioning method is as follows: the terminal equipment (ue) (user equipment) reports the acquired ue transceiving time difference to the positioning management function unit, and each transceiving point also provides the acquired next generation node B transceiving time difference to the positioning management function unit, and the positioning management function unit obtains the distance between the ue and each transceiving point by using the ue transceiving time difference and the next generation node B transceiving time difference. Then, together with other known information (e.g., geographical coordinates of the transceiving points), the location of the user equipment is calculated. Therefore, for the round trip time positioning method, in order to complete the measurement of the ue transceiving time difference or the next generation node B transceiving time difference, the transceiving point needs to send the downlink positioning reference signal and the ue sends the sounding reference signal for positioning, and then the ue or the next generation node B can complete the measurement of the related measurement quantity based on the downlink positioning reference signal and the sounding reference signal for positioning.
For the current Multi-Round Trip Time (RTT Time) Positioning method, in order to complete the measurement of the transmission/reception Time difference of the user equipment (terminal) or the transmission/reception Time difference of each transmission/reception point, a transmission/reception point trp (transmit and Receive point) needs to send a downlink Positioning Reference Signal DL-PRS (downlink Positioning Reference Signal) and a terminal UE sends a sounding Reference Signal SRS-Pos (sounding Reference Signal for Positioning), and then the UE or the gNB can complete the measurement of the related measurement quantity based on the DL-RTT and SRS-Pos. However, in the conventional protocol, when calculating positioning time measurement quantities such as UE transmission/reception time differences or base station gnb (next Generation Node b) transmission/reception time differences, the protocol assumes that time measurement is performed at the Antenna Connector (Antenna Connector) position, but in practice, since the time measurement position of a signal is in the baseband unit, there is a time measurement error, which is referred to as a transmission/reception timing error, for both signal transmission and signal reception. The existence of the transceiving timing error may cause inaccurate measurement results of all time-based positioning measurement quantities including UE transceiving time difference and gNB transceiving time difference, thereby affecting final positioning accuracy. In order to solve the problem, an embodiment of the present application provides an information indication method, where the method carries antenna index related information of at least one network element in the sending or receiving positioning assistance information and/or the positioning measurement result information, so that a corresponding receiving and sending positioning error value can be determined according to the antenna index related information, thereby avoiding an influence of a receiving and sending timing error on positioning calculation accuracy, and improving system positioning accuracy. The information indication method, apparatus, terminal device, network device and storage medium provided by the present application will be explained and explained in detail by specific embodiments below.
It should be noted that, in the following description, since the method and the apparatus are based on the same application concept, and the principles of solving the problems of the method and the apparatus are similar, the implementation of the apparatus and the method can be mutually referred, and repeated details are not repeated.

The present application will be specifically described below with reference to specific examples.
The first embodiment:
in this embodiment, the positioning assistance information and/or the positioning measurement result information sent or received by at least one network element of the UE, the TRP, the gNB, and the LMF carries antenna index related information associated with at least one information of an antenna panel index number, an antenna connector index number, an antenna index number, and a radio frequency chain index number of the at least one network element of the UE, the TRP, the gNB, and the LMF.
The antenna index related information is defined as follows:
the antenna index related information is an antenna panel index number: refers to an index number of a transmitting antenna panel or a receiving antenna panel of the UE, the TRP, or the gNB.
The antenna index related information is an index number of an antenna connector, which refers to an index number of a transmitting antenna connector or a receiving antenna connector of the UE, the TRP, or the gNB.
The antenna index related information is an antenna index number: refers to the index number of the transmitting antenna or the receiving antenna of the UE, the TRP or the gNB.
The antenna index related information is a radio frequency chain index number: refers to an index number of a transmitting radio frequency chain or a receiving radio frequency chain of the UE, the TRP, or the gNB.
As shown in fig. 5, the antenna index related information refers to an antenna panel index number. When UE, TRP, or gNB transmits a wireless signal, the signal is generated in the baseband unit, passes through the intermediate unit, and finally enters the transmitting antenna panel, and is transmitted. Similarly, when the UE, the TRP, or the gNB receives a wireless signal, the signal is received by the receiving antenna panel first, and then goes to the baseband unit after passing through the intermediate unit, thereby completing the reception of the wireless signal. Fig. 6, 7 and 8 respectively show diagrams when the antenna index related information is an antenna connector index number, an antenna index number and a radio frequency chain index number.
In this embodiment, different transmitting antenna panel index numbers correspond to different transmitting timing errors, and different receiving antenna panel index numbers correspond to different receiving timing errors. The transmission timing error refers to a signal transmission time error from the baseband unit to the transmission antenna, and the reception timing error refers to a signal transmission time error from the reception antenna to the baseband unit.
In this embodiment, the information related to the antenna panel, the antenna connector, the antenna or the radio frequency chain index number of the UE, the TRP or the gNB is indicated to assist the LMF or the UE in determining the correspondence between the transceiving timing error of the time measurement and the antenna panel, the antenna connector, the antenna or the radio frequency chain index number, so that the LMF or the UE can compensate or adjust the time measurement when calculating the terminal position by using the information, thereby avoiding the influence of the transceiving timing error on the calculation accuracy of the terminal position and improving the positioning accuracy of the system.
Second embodiment:
in this embodiment, the positioning assistance information and/or the positioning measurement result information sent or received by at least one network element of the UE, the TRP, the gNB, and the LMF carries antenna index related information associated with at least one information of an antenna panel index number, an antenna connector index number, an antenna index number, and a radio frequency chain index number of the at least one network element of the UE, the TRP, the gNB, and the gNB.
The antenna index related information includes the following contents:
1. antenna panel index number:
transmitting antenna panel index number information of DL-PRS;
receiving antenna panel index number information of DL-PRS;
transmitting antenna panel index number information of the UL-SRS;
receive antenna panel index number information for UL-SRS.
2. Antenna connector index number:
DL-PRS sending antenna connector index number information;
index number information of a receiving antenna connector of the DL-PRS;
index number information of a transmitting antenna connector of the UL-SRS;
receive antenna connector index number information for UL-SRS.
3. Antenna index number:
transmitting antenna index number information of DL-PRS;
receiving antenna index number information of DL-PRS;
transmitting antenna index number information of the UL-SRS;
receive antenna index number information for UL-SRS.
4. Index number of radio frequency chain:
transmitting radio frequency chain index number information of DL-PRS;
receiving radio frequency chain index number information of DL-PRS;
transmitting radio frequency chain index number information of the UL-SRS;
and receiving radio frequency chain index number information of the UL-SRS.
In this embodiment, considering that the time measurement is measured by using two positioning reference signals, i.e. DL-PRS or UL-SRS, the signal transmitted or received through the antenna panel, the antenna connector, the antenna or the radio frequency chain is the DL-PRS or UL-SRS. Thus, the antenna index related information refers to the series of index numbers of transmission or reception of the DL-PRS or UL-SRS.
Taking the index number of the antenna panel at the UE side as an example, as shown in fig. 9, the UE side has 4 antenna panels, which are numbered 1-4 respectively. Since the UE transmits the UL-SRS and receives the DL-PRS, the antenna index related information refers to the index number of the transmit antenna panel of the UL-SRS and the index number of the receive antenna panel of the DL-PRS.
In this embodiment, it should be noted that the information related to the antenna panel, the antenna connector, the antenna or the radio frequency chain index number of the UE, the TRP or the gNB is indicated to assist the LMF or the UE in determining the corresponding relationship between the transceiving timing error of the time measurement and the antenna panel, the antenna connector, the antenna or the radio frequency chain index number, so that the LMF or the UE can compensate or adjust the time measurement by using the information when calculating the terminal position, thereby avoiding the influence of the transceiving timing error on the terminal position calculation accuracy, and improving the system positioning accuracy.
The third embodiment:
in this embodiment, the positioning assistance information and/or the positioning measurement result information sent or received by at least one network element of the UE, the TRP, the gNB, and the LMF carries antenna index related information associated with at least one information of an antenna panel index number, an antenna connector index number, an antenna index number, and a radio frequency chain index number of the at least one network element of the UE, the TRP, the gNB, and the LMF. Whether the UE can obtain or report the antenna index related information is a UE Capability (UE Capability). If the UE has the capability of acquiring or reporting the antenna index related information, the UE transmits the antenna index related information in the positioning auxiliary information and/or the positioning measurement result information; if the UE does not have the capability of obtaining or reporting the antenna index related information, the UE will not transmit the antenna index related information in the positioning assistance information and/or the positioning measurement result information.
Specifically, for the UE, the cost and complexity are limited, the obtaining or reporting capabilities of all UEs are not the same, and some low-cost UEs only have simpler functions and can only obtain or report limited information. The antenna index related information is information related to a transmit-receive timing error of the UE or the gNB, and is information for assisting the LMF or the UE in improving the positioning accuracy in positioning calculation, so some UEs may not have the capability of obtaining or reporting the antenna index related information, and therefore, whether the UE can obtain or report the antenna index related information is a UE capability.
In this embodiment, it can be understood that whether the UE can obtain or report the antenna guidance related information is a UE capability. Therefore, for the UE with the capability of obtaining or reporting the antenna index related information, the antenna index related information can be obtained or reported, and the LMF or the UE is assisted to improve the positioning accuracy in positioning calculation. For low cost UEs, this capability may not be required, which may reduce the cost and complexity of the UE.
The fourth embodiment:
in this embodiment, it should be noted that the antenna index related information has a corresponding relationship with the UE, TRP, or gNB transceiving time error, and when the UE or LMF performs positioning calculation, the UE, TRP, or gNB transceiving timing error value or transceiving timing delay value may be determined according to the antenna index related information.
The receiving and sending timing error values or the receiving and sending timing delay values corresponding to a plurality of antenna panels or antenna connectors or antennas or radio frequency chain index numbers of the UE, the TRP or the gNB are in the form of a plurality of absolute reference values, wherein the plurality of absolute reference values refer to a plurality of receiving and sending timing error absolute values corresponding to a plurality of antenna panels or antenna connectors or antennas or radio frequency chain index numbers.
The transceiving timing error values or transceiving timing delay values corresponding to a plurality of antenna panels or antenna connectors or antennas or radio frequency chain index numbers of the UE, the TRP or the gNB take the form of an absolute reference value and a plurality of relative values, wherein an absolute reference value refers to a transceiving timing error absolute value corresponding to a certain antenna panel or antenna connector or antenna or radio frequency chain index number, and a plurality of relative values refer to a plurality of transceiving timing error relative values of a plurality of antenna panels or antenna connectors or antennas or radio frequency chain index numbers relative to the absolute reference value.
For the UE-assisted positioning scheme:
and the UE and the gNB report the antenna index related information to the LMF, so that when the LMF performs positioning calculation, the corresponding UE or the gNB is selected to receive and transmit a positioning error correction value according to an antenna panel or an antenna connector or an antenna or a radio frequency chain related to the time-based measurement quantity, and then the LMF performs correction processing on the time-based measurement quantity.
For the UE-based positioning scheme:
and the gNB and the LMF inform the UE of the antenna index related information, so that when the UE performs positioning calculation, the corresponding UE or the gNB receives and transmits a positioning error correction value according to an antenna panel or an antenna connector or an antenna or a radio frequency chain related to the time-based measurement quantity, and then the UE performs correction processing on the time-based measurement quantity.
Taking the index number of the antenna panel on the gbb side as an example, as shown in fig. 9, the gbb side has 4 antenna panels, which are numbered 1-4 respectively. Since the gNB transmits DL-PRS and receives UL-SRS, the antenna index related information refers to the DL-PRS transmission antenna panel index and the UL-SRS reception antenna panel index.
For the mapping relationship between the multiple antenna panels of the gNB and the transceiving timing error value or the transceiving timing delay value, the multiple absolute reference values may be used, or one absolute reference value and multiple relative values may be used.
If a mapping manner of multiple absolute reference values is adopted, the corresponding relationship between the index numbers of the 4 antenna panels and the corresponding transceiving timing error values, and the specific absolute values of the transceiving timing errors are respectively given, as shown in table 1 below:
TABLE 1
| Serial number | Antenna index related information | Corresponding transmit-receive |
| 1 | Transmission |
The gNB side sends timing errors: 3.5 |
| 2 | Transmission |
The gNB side sends timing errors: 2.8 ns |
| 3 | Reception |
The gbb side receives timing errors: 4.2 |
| 4 | Reception |
The gbb side receives timing errors: 3.9 nanoseconds |
If an absolute reference value and a plurality of relative values are mapped, the corresponding relationship between the index numbers of the 4 antenna panels and the corresponding transmit-receive timing error values, the specific absolute value of the first transmit-receive timing error, and the difference between the other three transmit-receive timing errors and the first transmit-receive timing error are given, as shown in table 2 below:
TABLE 2
It can be understood that, in the present embodiment, for different positioning schemes, the multiple absolute reference values may be adopted, or one absolute reference value and multiple relative values may be adopted to transmit the transceiving timing error information and the mapping relationship between the multiple antenna panels and the transceiving timing error value or the transceiving timing delay value, so as to assist the LMF or the UE in compensating or processing the transceiving timing error for different positioning schemes when performing positioning calculation, thereby improving the positioning accuracy of the system.
