Description

Technical Field

[0001] The present application relates to the field of communication technology, and in particular to an information indication method, apparatus, terminal equipment, network equipment and storage medium. Background Art

[0002] Among the existing positioning methods, the Multi-RTT positioning method is an important positioning method. The working principle of the Multi-RTT positioning method is: the UE reports the obtained UE receiving and sending time difference to the LMF, and each TRP also provides the obtained gNB receiving and sending time difference to the LMF. The LMF uses the UE receiving and sending time difference and the gNB receiving and sending time difference to obtain the distance between the UE and each TRP. Then, other known information (such as the geographic coordinates of the TRP) is added to calculate the UE's position.

[0003] Among them, in order to complete the measurement of the UE transceiver time difference or the gNB transceiver difference, the TRP needs to send DL-PRS and the UE needs to send SRS-Pos. The UE or gNB can complete the measurement of the relevant measurement quantities based on DL-PRS and SRS-Pos. In the existing protocol, when calculating positioning time measurement quantities such as the UE transceiver time difference or the gNB transceiver time difference, the protocol assumes that the time measurement is performed at the antenna connector (Antenna Connector) position. However, in fact, the time measurement position of the signal is in the baseband unit, so there will be a time measurement error. This error exists for both signal transmission and signal reception, and is called the transceiver timing error. The existence of the transceiver timing error will cause the measurement results of all time-based positioning measurement quantities, including the UE transceiver time difference and the gNB transceiver time difference, to be inaccurate, thereby affecting the final positioning accuracy.

[0191] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0192] It should be noted that if Figure 1 As shown, the working principle of the round-trip time positioning method is: the terminal equipment UE (User Equipment) reports the obtained user equipment receiving and sending time difference to the positioning management function unit, and each transceiver point also provides the obtained next-generation node B receiving and sending time difference to the positioning management function unit, and the positioning management function unit uses the user equipment receiving and sending time difference and the next-generation node B receiving and sending time difference to obtain the distance between the user equipment and each receiving and sending point. Then, other known information (such as the geographic coordinates of the receiving and sending point) is added to calculate the position of the user equipment. Therefore, for the round-trip time positioning method, in order to complete the measurement of the receiving and sending time difference of the user equipment or the receiving and sending time difference of the next-generation node B, the receiving and sending point needs to send a downlink positioning reference signal and the user equipment needs to send a detection reference signal for positioning. Then, the user equipment or the next-generation node B can complete the measurement of the relevant measurement quantity based on the downlink positioning reference signal and the detection reference signal for positioning.

[0193] For the current Multi-RTT (Multiple-Round Trip Time) positioning method, in order to complete the measurement of the time difference between the user equipment (terminal) and the time difference between the transmission and reception of each transmission and reception point, the transmission and reception point TRP (Transmit and Receive Point) needs to send the downlink positioning reference signal DL-PRS (Downlink Positioning Reference Signal) and the terminal UE needs to send the sounding reference signal SRS-Pos (Sounding Reference Signal for Positioning) for positioning. Then the UE or gNB can complete the measurement of the relevant measurement quantity based on DL-PRS and SRS-Pos. However, in the existing protocol, when calculating the positioning time measurement quantity such as the UE transmission and reception time difference or the base station gNB (next Generation Node B) transmission and reception time difference, the protocol assumes that the time measurement is performed at the antenna connector position. However, in fact, the signal time measurement position is at the baseband unit, so there will be a time measurement error. This error exists for both signal transmission and signal reception, and is called the transmission and reception timing error. The existence of the transceiver timing error will cause inaccurate measurement results of all time-based positioning measurement quantities, including the UE transceiver time difference and the gNB transceiver time difference, thereby affecting the final positioning accuracy. To solve this problem, an embodiment of the present application provides an information indication method, which carries antenna index related information of at least one network element in the sending or receiving positioning assistance information and / or positioning measurement result information, so that the corresponding transceiver positioning error value can be determined according to the antenna index related information, thereby avoiding the influence of the transceiver timing error on the positioning calculation accuracy, thereby improving the system positioning accuracy. The information indication method, device, terminal device, network device and storage medium provided in the present application will be explained and illustrated in detail through specific embodiments below.

[0194] It should be noted that in the following description, since the method and the device are based on the same application concept and the principles of solving the problem are similar, the implementation of the device and the method can refer to each other and the repeated parts will not be repeated.

Since the terminal equipment and other network equipment (such as core network equipment and access network equipment (i.e., base station)) together constitute a network that can support communication, in the present invention, the terminal equipment is also regarded as a network equipment.

[0197] The network device involved in the embodiments of the present application may be a base station, which may include multiple cells providing services for the terminal, or a CU (Central Unit) or a DU (Distributed Unit). Depending on the specific application scenario, the network device may also be called an access point, or may be a device in an access network that communicates with a wireless terminal device through one or more sectors on an air interface, or other names.

[0202] Step 101: Send or receive positioning assistance information and / or positioning measurement result information, where the positioning assistance information and / or positioning measurement result information carries information related to an antenna index of at least one network element;

[0203] Perform positioning calculation according to the antenna index related information of the at least one network element.

[0204] In this step, at least one network element on the terminal device side receives the positioning assistance information and / or positioning measurement result information sent by the transceiver point TRP or the base station gNB, which carries the antenna index related information associated with at least one of the antenna panel index number, antenna connector index number, antenna index number and radio frequency chain index number of at least one network element of the TRP or gNB. For example, the received positioning assistance information and / or positioning measurement result information carries the antenna panel index number and antenna connector index number information of the TRP, or the received positioning assistance information and / or positioning measurement result information carries the antenna panel index number and antenna connector index number information of the gNB, or the received positioning assistance information and / or positioning measurement result information carries the antenna panel index number, antenna connector index number, antenna index number and radio frequency chain index number information of the TRP.

[0207] In this step, it should be noted that the antenna index related information corresponds to the UE, TRP or gNB transceiver time error. When the UE performs positioning solution, it can determine the corresponding UE, TRP or gNB transceiver timing error value or transceiver timing delay value through the antenna index related information (antenna panel index number, antenna connector index number, antenna index number and RF chain index number), so that the measured transceiver time difference can be corrected by using the transceiver timing error value or transceiver timing delay value, thereby solving the problem of low terminal position calculation accuracy caused by the existence of transceiver timing error in the prior art.

When performing positioning solution, the UE can determine the corresponding UE, TRP or gNB transceiver timing error value or transceiver timing delay value through the antenna index related information (antenna panel index number, antenna connector index number, antenna index number and RF chain index number), and then use the transceiver timing error value or transceiver timing delay value to perform positioning calculation, which can solve the problem of low terminal position calculation accuracy caused by the existence of transceiver timing error in the prior art.

[0404] The present application is described in detail below through specific embodiments.

[0405] First embodiment:

[0406] In this embodiment, the positioning assistance information and / or positioning measurement result information sent or received by at least one network element among the UE, TRP, gNB and LMF carries antenna index related information associated with at least one of the antenna panel index number, antenna connector index number, antenna index number and RF chain index number of at least one network element among the UE, TRP and gNB.

[0407] The definition of antenna index related information is as follows:

[0408] The antenna index related information is the antenna panel index number: it refers to the index number of the transmitting antenna panel or the receiving antenna panel of the UE, TRP or gNB.

[0409] The antenna index related information is that the antenna connector index number refers to the index number of the transmitting antenna connector or the receiving antenna connector of the UE, TRP or gNB.

[0410] The antenna index related information is the antenna index number: it refers to the index number of the transmitting antenna or receiving antenna of the UE, TRP or gNB.

[0411] The antenna index related information is the RF chain index number: it refers to the index number of the transmitting RF chain or receiving RF chain of the UE, TRP or gNB.

[0412] like Figure 5 As shown, the antenna index related information refers to the antenna panel index number. When a UE, TRP or gNB sends a wireless signal, the signal is generated by the baseband unit, passes through the intermediate unit, and finally enters the transmitting antenna panel to be sent out. Similarly, when a UE, TRP or gNB receives a wireless signal, the signal is first received by the receiving antenna panel, then passes through the intermediate unit, and then enters the baseband unit to complete the reception of the wireless signal. Figure 6 , Figure 7 and Figure 8 The schematic diagrams respectively show the case where the antenna index related information is the antenna connector index number, the antenna index number and the radio frequency chain index number.

[0413] In this embodiment, different transmit antenna panel index numbers correspond to different transmit timing errors, and different receive antenna panel index numbers correspond to different receive timing errors. The transmit timing error refers to the signal transmission time error from the baseband unit to the transmit antenna, and the receive timing error refers to the signal transmission time error from the receive antenna to the baseband unit.

[0414] In this embodiment, by indicating information related to the antenna panel, antenna connector, antenna or RF chain index number of the UE, TRP or gNB, the LMF or UE is assisted in determining the correspondence between the receive and transmit timing error of the time measurement amount and the antenna panel, antenna connector, antenna or RF chain index number, so that the LMF or UE can use the information to compensate or adjust the time measurement amount when calculating the terminal position, thereby avoiding the influence of the receive and transmit timing error on the accuracy of the terminal position calculation, thereby improving the system positioning accuracy.

[0415] Second embodiment:

[0416] In this embodiment, the positioning assistance information and / or positioning measurement result information sent or received by at least one network element among the UE, TRP, gNB and LMF carries antenna index related information associated with at least one of the antenna panel index number, antenna connector index number, antenna index number and radio frequency chain index number of at least one network element among the UE, TRP and gNB.

[0417] The antenna index related information includes the following:

[0418] 1. Antenna panel index number:

[0419] DL-PRS transmit antenna panel index number information;

[0420] DL-PRS receiving antenna panel index number information;

[0421] UL-SRS transmit antenna panel index number information;

[0422] UL-SRS receiving antenna panel index number information.

[0423] 2. Antenna connector index number:

[0424] DL-PRS transmit antenna connector index number information;

[0425] DL-PRS receiving antenna connector index number information;

[0426] UL-SRS transmit antenna connector index number information;

[0427] UL-SRS receiving antenna connector index number information.

[0428] 3. Antenna index number:

[0429] DL-PRS transmit antenna index information;

[0430] DL-PRS receiving antenna index information;

[0431] UL-SRS transmit antenna index information;

[0432] UL-SRS receiving antenna index information.

[0433] 4. RF chain index number:

[0434] DL-PRS transmission radio frequency chain index number information;

[0435] DL-PRS receiving radio frequency chain index number information;

[0436] UL-SRS transmission radio frequency chain index number information;

[0437] UL-SRS receiving radio frequency chain index information.

[0438] In this embodiment, considering that the time measurement amount is measured using two positioning reference signals, DL-PRS or UL-SRS, the signal sent or received through the antenna panel, antenna connector, antenna or radio frequency chain is DL-PRS or UL-SRS. In this way, the antenna index related information refers to the series of index numbers of the transmission or reception of DL-PRS or UL-SRS.

[0439] Take the UE side antenna panel index number as an example. Fig. 9 As shown, the UE side has 4 antenna panels, which are numbered 1 to 4. Since the UE sends UL-SRS and receives DL-PRS, the antenna index related information refers to the transmit antenna panel index number of the UL-SRS and the receive antenna panel index number of the DL-PRS.

[0440] In this embodiment, it should be noted that by indicating information related to the antenna panel, antenna connector, antenna or RF chain index number of the UE, TRP or gNB, the LMF or UE is assisted in determining the correspondence between the receive and transmit timing error of the time measurement amount and the antenna panel, antenna connector, antenna or RF chain index number, so that the LMF or UE can use the information to compensate or adjust the time measurement amount when calculating the terminal position, thereby avoiding the influence of the receive and transmit timing error on the accuracy of the terminal position calculation, thereby improving the system positioning accuracy.

[0441] Third embodiment:

[0442] In this embodiment, the positioning assistance information and / or positioning measurement result information sent or received by at least one network element among the UE, TRP, gNB and LMF carries antenna index related information associated with at least one of the antenna panel index number, antenna connector index number, antenna index number and RF chain index number of at least one network element among the UE, TRP and gNB. Whether the UE can obtain or report antenna index related information is a UE capability (UE Capability). If the UE has the ability to obtain or report antenna index related information, the UE will transmit antenna index related information in the positioning assistance information and / or positioning measurement result information; if the UE does not have the ability to obtain or report antenna index related information, the UE will not transmit antenna index related information in the positioning assistance information and / or positioning measurement result information.

[0443] Specifically, for UE, due to cost and complexity, not all UEs have the same acquisition or reporting capabilities. Some low-cost UEs have only simpler functions and can only obtain or report limited information. Antenna index related information is information associated with the UE or gNB's transmit and receive timing error, which is used to assist LMF or UE in improving positioning accuracy in positioning solution. Therefore, some UEs may not have the ability to obtain or report antenna index related information. Therefore, whether the UE can obtain or report antenna index related information is a UE capability.

[0444] In this embodiment, it can be understood that whether the UE can obtain or report the antenna index related information is a UE capability. In this way, for a UE with the ability to obtain or report the antenna index related information, the antenna index related information can be obtained or reported, thereby assisting the LMF or UE to improve the positioning accuracy in the positioning solution. For low-cost UEs, this capability may not be required, thereby reducing the cost and complexity of the UE.

[0445] Fourth embodiment:

[0446] In this embodiment, it should be noted that the antenna index related information corresponds to the UE, TRP or gNB transmit and receive time error. When the UE or LMF performs positioning solution, the antenna index related information can be used to determine the corresponding UE, TRP or gNB transmit and receive timing error value or transmit and receive timing delay value.

[0447] The transmit / receive timing error values ​​or transmit / receive timing delay values ​​corresponding to multiple antenna panels or antenna connectors or antennas or RF chain index numbers of the UE, TRP or gNB are in the form of multiple absolute reference values, where the multiple absolute reference values ​​refer to multiple transmit / receive timing error absolute values ​​corresponding to multiple antenna panels or antenna connectors or antennas or RF chain index numbers.

[0448] The transmit / receive timing error values ​​or transmit / receive timing delay values ​​corresponding to multiple antenna panels or antenna connectors or antenna or RF chain index numbers of the UE, TRP or gNB are in the form of an absolute reference value and multiple relative values, where one absolute reference value refers to the absolute value of the transmit / receive timing error corresponding to a certain antenna panel or antenna connector or antenna or RF chain index number, and the multiple relative values ​​refer to multiple transmit / receive timing error relative values ​​of multiple antenna panels or antenna connectors or antenna or RF chain index numbers relative to the absolute reference value.

[0449] For UE-assisted positioning solutions:

[0450] The UE and gNB report the antenna index related information to the LMF for LMF to use for positioning solution. According to the antenna panel or antenna connector or antenna or RF chain associated with the time-based measurement quantity, the corresponding UE or gNB transceiver positioning error correction value is selected, and then the LMF corrects the time-based measurement quantity for use.

[0451] For UE-based positioning solutions:

[0452] The gNB and LMF notify the UE of the antenna index related information so that when the UE performs positioning solution, it selects the corresponding UE or gNB to send and receive positioning error correction values ​​based on the antenna panel or antenna connector or antenna or RF chain associated with the time-based measurement quantity, and then the UE corrects the time-based measurement quantity for use.

[0453] Take the gNB side antenna panel index number as an example. Fig. 9 As shown, the gNB side has 4 antenna panels, numbered 1 to 4. Since the gNB sends DL-PRS and receives UL-SRS, the antenna index related information refers to the transmit antenna panel index number of DL-PRS and the receive antenna panel index number of UL-SRS.

[0454] The mapping relationship between the multiple antenna panels of the gNB and the transmit / receive timing error value or the transmit / receive timing delay value may be in the form of multiple absolute reference values ​​or in the form of one absolute reference value and multiple relative values.

[0455] If a mapping method of multiple absolute reference values ​​is adopted, the corresponding relationship between the index numbers of the four antenna panels and the corresponding transmit and receive timing error values, as well as the specific absolute values ​​of these transmit and receive timing errors are given respectively, as shown in the following Table 1:

[0456] Table 1

[0457] Serial number Antenna index related information The corresponding transmit and receive timing error value 1 DL-PRS Transmit Antenna Panel #1 gNB side transmission timing error: 3.5 nanoseconds 2 DL-PRS Transmit Antenna Panel #2 gNB side transmission timing error: 2.8 nanoseconds 3 UL-SRS receiving antenna panel #3 gNB side receiving timing error: 4.2 nanoseconds 4 UL-SRS receiving antenna panel #4 gNB side receiving timing error: 3.9 nanoseconds

[0458] If an absolute reference value and a plurality of relative values ​​are used for mapping, the corresponding relationship between the index numbers of the four antenna panels and the corresponding transmit / receive timing error values, as well as the specific absolute value of the first transmit / receive timing error, are given, plus the differences of the other three transmit / receive timing errors relative to the first transmit / receive timing error, as shown in Table 2 below:

[0459] Table 2

[0460]

[0461]

[0462] It can be understood that this embodiment can adopt the form of multiple absolute reference values ​​or one absolute reference value and multiple relative values ​​to transmit the transmit and receive timing error information and the mapping relationship between multiple antenna panels and the transmit and receive timing error values ​​or the transmit and receive timing delay values ​​for different positioning schemes, thereby assisting the LMF or UE to compensate or process the transmit and receive timing error for different positioning schemes when performing positioning solution, thereby improving the system positioning accuracy.
