Description

[0001] This invention application is a divisional application of the invention application with application date of August 9, 2019, application number 201910734624.9, and invention name “A measurement reporting and receiving method, device and equipment”. Technical Field

[0002] The present invention relates to the field of communication technology, and in particular to a measurement reporting and receiving method, device and equipment. Background Art

[0003] In order to obtain the geographical location information of the terminal, a common terminal positioning method in the prior art is to measure the downlink angle of departure (DL-AoD) from multiple network-side sending devices to the terminal. The location of the terminal can be calculated by using the downlink angle of departure from multiple network-side sending devices to the terminal. Specifically, the network-side sending device can be a base station or a transceiver point (TRP).

[0004] In the New Radio (NR) system, each base station sends multiple downlink positioning reference signals (PRS), and each positioning reference signal points to a different direction after being shaped. The terminal measures the reference signal received power (RSRP) of each beam and feeds back the RSRP value of each beam to the positioning server on the network side. The positioning server determines the departure angle from the corresponding base station to the terminal based on the RSRP value of each beam received, and then determines the location information of the terminal.

[0005] Figure 1 A schematic diagram of the principle of downlink departure angle measurement in the prior art is given. Figure 1 In the example, terminal 14 measures multiple beams in base station 11, base station 12, and base station 13 respectively. For example, after terminal 14 measures three beams of base station 11, such as beams 15 to 17, it feeds back the RSRP corresponding to each beam. Based on the RSRP of the above three beams and the transmission angles corresponding to the three beams known to the server, the positioning server can obtain the arrival angle from base station 11 to terminal 14 by interpolation. Similarly, base station 12 and base station 13 perform the same operation. In this way, after obtaining the arrival angles from multiple base stations to terminal 14, the positioning server can use the existing angle-based algorithm to calculate the terminal's location information.

However, the following description describes an NR system for example purposes and uses NR terminology in much of the following description, although the techniques may also be applicable to applications other than NR system applications.

[0075] The following description provides examples and does not limit the scope, applicability, or configuration set forth in the claims. Changes may be made to the functions and arrangements of the elements discussed without departing from the spirit and scope of the present disclosure. Various examples may appropriately omit, replace, or add various procedures or components. For example, the described methods may be performed in an order different from that described, and various steps may be added, omitted, or combined. In addition, features described with reference to certain examples may be combined in other examples.

[0076] As mentioned above, in the positioning solution based on the downlink departure angle in the prior art, the terminal needs to feedback the RSRP of the beams of multiple base stations measured by it, and each base station includes multiple beams. For example, the terminal measures M base stations, each of which contains N transmit beams. In this way, the terminal needs to feedback M×N RSRP values. The reporting of these measurement quantities will occupy a large resource overhead.

[0077] In order to reduce the resource overhead of positioning measurement reporting, an embodiment of the present invention provides a measurement reporting method, such as Figure 2 As shown, when the method is applied to the terminal side, it includes:

[0078] In step 21, the terminal measures positioning reference signals sent by multiple network-side sending devices, and determines departure angle indication information of the network-side sending device based on multiple positioning reference signals sent by the same network-side sending device.

[0079] Here, the above-mentioned network side sending device may specifically be a base station and / or a transceiver point (TRP, Transmission Reception Point). Generally, a cell may include joint coverage by multiple TRPs. The terminal may measure the positioning reference signals (PRS) sent by multiple network side sending devices, and for each network side sending device, determine the departure angle indication information of the network side sending device according to the measurement results (such as RSRP) of the multiple positioning reference signals sent by the network side sending device, so that the departure angle indication information of each of the multiple network side sending devices can be obtained.

[0080] Step 22: The terminal sends the departure angle indication information of the multiple network-side sending devices to the network-side positioning device.

[0081] Here, the network-side positioning device may be one of the above-mentioned multiple network-side sending devices, for example, one of the base stations or TRP, or a positioning server set up on the network side. The terminal sends the departure angle indication information obtained from the multiple network-side sending devices to the network-side positioning device, specifically, to the base station, TRP or positioning server on the network side. When sent to the positioning server, the above-mentioned departure angle indication information may be forwarded to the positioning server via the service base station (TRP) of the terminal.

[0082] Through the above steps, the embodiment of the present invention can send the departure angle indication information of multiple network-side sending devices to the network-side positioning device, so that the network-side positioning device can determine the location information of the terminal based on the departure angle indication information to achieve the positioning of the terminal. In the above measurement reporting method, the terminal no longer needs to report the RSRP values ​​of multiple positioning reference signals of multiple network-side sending devices, but only needs to report the departure angle indication information of each network-side sending device, thereby greatly reducing the resource overhead of positioning measurement reporting and saving signaling resources.

[0083] In an embodiment of the present invention, before the above step 21, the terminal may also receive measurement configuration information sent by a network-side positioning device (such as a base station or TRP), and the measurement configuration information includes configuration information of the positioning reference signal and configuration information of the reported measurement quantity. Among them, the configuration information of the positioning reference signal may specifically include information such as the time-frequency domain resource position of the positioning reference signal, and the measurement quantity includes departure angle indication information. In this way, the terminal can detect and measure the positioning reference signal sent by the network-side sending device according to the configuration information of the positioning reference signal, and, when performing the measurement, perform targeted measurement reporting according to the configuration information of the reported measurement quantity.

[0084] The departure angle indication information described in the embodiment of the present invention may specifically be one or more of the following information: a departure angle index corresponding to the departure angle; a value of the departure angle. Among them, the value of the departure angle is used to indicate the specific angle of the departure angle. The departure angle index corresponding to the departure angle is used to indicate the positioning reference signal corresponding to the departure angle. Since the positioning reference signal corresponding to the departure angle may be the same as a certain positioning reference signal sent by the network-side sending device, it may also be different from all positioning reference signals sent by the network-side sending device. Therefore, the departure angle index can be specifically represented by the index + offset of a known positioning reference signal, such as the index of a positioning reference signal among multiple positioning reference signals sent by the network-side sending device (i.e., the reference index), and the offset relative to the reference index. Of course, the above-mentioned departure angle index can also be directly represented by the index value of the departure angle index.

[0085] When the departure angle index is represented by the reference index and the offset, according to at least one embodiment of the present invention, determining the departure angle indication information in the above step 21 may specifically include:

[0086] A) The terminal may select a network side sending device that meets a preset condition according to the reference signal received power (RSRP) of positioning reference signals sent by multiple network side sending devices.

[0087] For example, according to the minimum number Y of network-side transmitting devices required for positioning, the first X network-side transmitting devices are selected according to the descending order of the maximum RSRP of the positioning reference signals sent by each network-side transmitting device, where X is greater than or equal to Y and less than or equal to the total number of the plurality of network-side transmitting devices. This can reduce the amount of calculation of the terminal to a certain extent.

[0088] For another example, according to the descending order of the maximum RSRP of the positioning reference signals sent by each network-side sending device, the network-side sending device whose maximum RSRP is greater than the preset threshold is selected. In this way, it can be ensured that the selected network-side sending device for calculating the departure angle indication information has a high reliability, thereby ensuring the accuracy of the calculated departure angle.

[0089] Of course, the embodiment of the present invention may not make any selection, so that when determining the departure angle indication information, the RSRP of the positioning reference signals of all network-side sending devices is used.

[0090] B) For each selected network side sending device, curve fitting is performed using the indexes and RSRP of multiple positioning reference signals sent by the network side sending device, and the reference index and index offset corresponding to the departure angle of the network side sending device are determined based on the position point of the maximum RSRP on the fitted curve.

[0091] Here, a curve fitting method can be used to obtain a fitting curve, and the position point of the maximum RSRP on the fitting curve is found. This position point corresponds to the departure angle index of the departure angle of the network side sending device, so that the index of a positioning reference signal sent by the network side sending device adjacent to the position point can be used as the reference index, and the index offset can be determined based on the distance between the position point and the reference index.

[0092] When the departure angle indication information is the value of the departure angle, according to some other embodiments of the present invention, determining the departure angle indication information in step 21 may specifically include:

[0093] a) The terminal may select a network side sending device that meets a preset condition according to the reference signal received power (RSRP) of positioning reference signals sent by multiple network side sending devices.

[0094] b) For each selected network-side transmitting device, curve fitting is performed using the indexes of multiple positioning reference signals sent by the network-side transmitting device and RSRP, and the departure angle index of the network-side transmitting device is determined according to the position point of the maximum RSRP on the fitted curve.

[0095] The above steps a and b are similar to the above steps A and B and will not be repeated here.

[0096] c) According to the pre-obtained angle information of the beam direction corresponding to each positioning reference signal sent by the network side sending device, determine the angle information corresponding to the departure angle index, and obtain the value of the departure angle of the network side sending device.

[0097] Here, curve fitting can also be performed using the indexes of multiple positioning reference signals sent by the network side sending device and the angle information of the beam direction corresponding to each positioning reference signal, and the value of the departure angle of the network side sending device can be determined based on the angle information corresponding to the departure angle index on the fitted curve.

[0098] In addition, when determining the departure angle index and the angle information corresponding to the departure angle index, the embodiment of the present invention may use curve fitting methods including but not limited to linear fitting and high-order polynomial fitting, etc., which are not specifically limited in the embodiment of the present invention.

[0099] In order to facilitate the calculation of the angle information corresponding to the departure angle index, before the above step 21, the terminal can also receive the angle information of the beam direction corresponding to the positioning reference signal sent by the network side sending device, so as to facilitate the above curve fitting calculation processing.

[0100] In addition, in the above step 22 of the embodiment of the present invention, the terminal may also send the RSRP corresponding to the departure angle indication information of the network side sending device to the network side positioning device, wherein the RSRP corresponding to the departure angle indication information of the network side sending device is the maximum RSRP on the curve fitted in the above step b or B. In this way, the network side positioning device can select a network side sending device whose RSRP is greater than a preset quality threshold from multiple network side sending devices according to the RSRP corresponding to the departure angle indication information of each network side sending device, and use the departure angle indication information of the selected network side sending device to locate the terminal, which can reduce the amount of calculation and improve the accuracy of the positioning result.

[0101] Please refer to Figure 3The measurement receiving method provided in the embodiment of the present invention is applied to a network-side positioning device, which may be one of a plurality of network-side sending devices, for example, a base station or TRP, or a positioning server arranged on the network side. Figure 3 As shown, the method includes:

[0102] Step 31: A network-side positioning device receives departure angle indication information of multiple network-side sending devices measured and reported by a terminal.

[0103] Here, the departure angle indication information includes at least one of the following information: a departure angle index corresponding to the departure angle; and a value of the departure angle. The departure angle index may be directly represented by the index value of the departure angle index, or may be represented by a reference index of a positioning reference signal among multiple positioning reference signals sent by a network-side sending device, and an offset relative to the reference index.

[0104] The network-side positioning device may specifically be a positioning server and / or a network-side sending device. The network-side sending device may specifically include a TRP and / or a base station. When the network-side device is a positioning server, the positioning server may receive departure angle indication information of multiple network-side sending devices reported by the terminal and forwarded via a serving base station (TRP).

[0105] Step 32: The network-side positioning device determines the location information of the terminal according to the departure angle indication information of the multiple network-side sending devices.

[0106] Here, when the departure angle indication information is the value of the departure angle of the network side sending device, the network side device can determine the location information of the terminal using various angle positioning algorithms based on the values ​​of the departure angles of the multiple network side sending devices. The specific angle positioning algorithm is not limited in this embodiment of the present invention.

[0107] When the departure angle indication information is the departure angle index corresponding to the departure angle, the network side device can determine the angle information corresponding to the departure angle index of the network side sending device according to the departure angle index corresponding to the departure angle of each network side sending device and the angle information of the beam direction corresponding to each positioning reference signal sent by the network side sending device, and obtain the value of the departure angle of the network side sending device; then, according to the values ​​of the departure angles of the multiple network side sending devices, the position information of the terminal is determined using an angle positioning algorithm. Specifically, to determine the angle information corresponding to the departure angle index of the network side sending device, you can refer to the curve fitting processing method in the previous text. To save space, it will not be described in detail here.

[0108] Through the above steps, the network side positioning device in the embodiment of the present invention only needs to receive the departure angle indication information of each network side sending device, without receiving the RSRP of each positioning reference signal sent by each network side sending device, to calculate the position of the terminal, thereby greatly reducing the resource overhead of positioning measurement reporting during the positioning process.

[0109] In addition, in the above step 32, if the location information of the terminal is determined by the positioning server on the network side based on the departure angle indication information of the multiple network side sending devices, then before determining the location information of the terminal, the positioning server on the network side may also receive the angle information of the beam direction corresponding to the positioning reference signal reported by the network side sending device, so that the positioning server can perform terminal positioning based on this.

[0110] In addition, according to at least one embodiment of the present invention, before the above step 31, the network-side positioning device (such as a base station or a TRP) may also send measurement configuration information to the terminal, wherein the measurement configuration information includes configuration information of the positioning reference signal and configuration information of the reported measurement quantity, and the measurement quantity includes departure angle indication information. In this way, the terminal can detect and measure the positioning reference signal sent by the network-side sending device according to the configuration information of the positioning reference signal, and, when performing the measurement, perform targeted measurement reporting according to the configuration information of the reported measurement quantity.

[0111] Optionally, in the above step 31, the network-side positioning device may also receive RSRP corresponding to the departure angle indication information of multiple network-side sending devices sent by the terminal. In the above step 32, the network-side positioning device may select a network-side sending device whose RSRP is greater than a preset quality threshold from multiple network-side sending devices based on the RSRP corresponding to the departure angle indication information of the network-side sending device, and determine the location information of the terminal based on the departure angle indication information of the selected network-side sending device. The above processing method can ensure the credibility of the departure angle used for terminal positioning processing, reduce the calculation amount of positioning processing and improve the accuracy of positioning results.

[0112] Optionally, in order to facilitate the terminal to calculate the value of the departure angle, before the above step 31, the network side positioning device (such as a base station or TRP) may also indicate the angle information of the beam direction corresponding to the positioning reference signal to the terminal, so that the terminal can use the above angle information to calculate the value of the departure angle and report it to the network side positioning device.

[0113] The measurement reporting and receiving method of the embodiment of the present invention is described above from the perspectives of the terminal and the network. The following further describes the above method through two examples of interaction between the terminal and the network.

[0114] Example 1:

[0115] This example 1 is described by taking the departure angle index corresponding to the departure angle as an example.

[0116] Assume that each transceiver point (TRP) is configured with M=8 positioning reference signal (PRS) resources, and each PRS is shaped differently and points to different directions. The network side (which can be a positioning server or a base station) configures the terminal to report N=6 TRP departure angle indication information, and indicates the configuration information of the PRS resources of the transceiver point to the terminal.

[0117] 1) The base station reports the corresponding angle information of each PRS after shaping among the M=8 PRSs sent by each TRP to the positioning server.

[0118] 2) The terminal determines the RSRP of each of the M=8 PRSs sent by each TRP. And determines N=6 TRPs to report the departure angle indication information. One way to determine is that among the N=6 TRPs, the maximum RSRP of the M=8 PRSs sent by each TRP is ranked in the first 6.

[0119] 3) The terminal determines the departure angle indication information for each of the N=6 TRPs. Taking the Kth TRP as an example, the RSRPs measured are respectively represented as RSRP1, RSRP2, ..., RSRP8. Linear interpolation, second-order interpolation or high-order interpolation measurement is performed on these 8 RSRPs, such as Figure 4 As shown, by fitting the curve with a high-order polynomial, the maximum RSRP on the curve (i.e., the RSRP at the dotted line) can be obtained. The reference index of the reference signal corresponding to the maximum RSRP is 3, and the index offset is 0.5, that is, the index value of the departure angle index is 3+0.5=3.5. At the same time, the value of the maximum RSRP at the dotted line can also be calculated by the fitted polynomial.

[0120] 4) The terminal reports the departure angle indication information of each TRP in N=6 TRPs (ie, the departure angle index corresponding to the departure angle) to the positioning server.

[0121] 5) The positioning server determines the departure angle of the N=6 TRPs according to the angle information corresponding to each PRS sent by each TRP in the N=6 TRPs reported by the base station in advance, and the departure angle indication information of each TRP reported by the terminal. A method for determining the departure angle is as follows: Figure 5 As shown, for the Kth TRP, the positioning server knows the angle information corresponding to M = 8 PRSs, expressed as θ 1 ,θ 2 ,…,θ 8Here, a linear fitting method can be used, and the positioning server can determine the angle information at an index of 3 and an offset of 0.5, which is the departure angle corresponding to this TRP.

[0122] 6) The positioning server can obtain the terminal's location information based on the 6 departure angles corresponding to N=6 TRPs using the existing angle positioning algorithm.

[0123] Example 2:

[0124] This Example 2 is described by taking the departure angle indication information as the value of the departure angle as an example.

[0125] Assume that each transceiver point (TRP) is configured with M=8 PRS resources, and each PRS is shaped differently and points to a different direction.

[0126] 1) The network side (which may be a positioning server or a base station) configures the terminal to report a departure angle indication information of N=6 TRPs, and indicates the configuration information of the PRS resources of the transceiver point to the terminal.

[0127] 2) The base station reports the corresponding angle information of each PRS after shaping among the M=8 PRSs sent by each TRP to the positioning server.

[0128] 3) The positioning server indicates the angle information corresponding to each PRS in the PRS sent by each TRP to the terminal.

[0129] 4) The terminal determines the RSRP of each of the M=8 PRSs sent by each TRP, and determines N=6 TRPs from them to report the departure angle indication information. One way to determine is that among the N=6 TRPs, the maximum RSRP of the M=8 PRSs sent by each TRP is ranked in the first 6.

[0130] 5) The terminal determines the departure angle indication information for each of the N=6 TRPs. Taking the Kth TRP as an example, the RSRPs measured are respectively represented as RSRP1, RSRP2, ..., RSRP8. Linear interpolation, second-order interpolation or high-order interpolation are performed on these 8 RSRPs. Figure 4 As shown in the figure, the high-order polynomial fitting is used as an example, and the maximum RSRP (i.e., the RSRP at the dotted line) can be obtained. The corresponding reference signal index is 3, and the index offset is 0.5, that is, the index value of the departure angle index is 3.5. At the same time, the RSRP value at the dotted line can also be calculated by the fitted polynomial.

[0131] 6) The terminal determines the departure angles of N=6 TRPs according to the angle information corresponding to each PRS indicated by the positioning server. Figure 5Taking the curve fitting shown in the figure as an example, for the Kth TRP, the terminal knows the angle information corresponding to M = 8 PRSs, which is expressed as θ 1 ,θ 2 ,…,θ 8 By using linear fitting, the positioning server can determine the angle information at an index of 3 and an offset of 0.5, which is the departure angle corresponding to this TRP.

[0132] 7) The terminal reports the 6 departure angles corresponding to the determined N=6 TRPs as departure angle indication information to the positioning server.

[0133] 8) The positioning server can obtain the terminal's location information using the existing angle positioning algorithm.
