Description

Technical Field

[0001] This invention relates to the field of wireless communication technology, and in particular to a positioning method, apparatus, device, and storage medium. Background Technology

[0002] 3GPP provides a method for positioning based on New Radio (NR) signals in Rel-16. NR positioning technology includes downlink positioning, uplink positioning, and hybrid uplink / downlink positioning. In downlink positioning, the UE (terminal) measures the downlink positioning reference signal (DL PRS) to obtain positioning measurements and reports them to the positioning server. Downlink positioning technology includes NR downlink time difference of arrival (DL-TDOA) and NR downlink angle of departure (DL-Angle of Arrival). Departure (DL-AoD); Uplink positioning technology involves the gNB (base station) measuring the uplink-sounding reference signal (UL SRS) to obtain positioning measurements and reporting them to the positioning server. Uplink positioning technology includes NR uplink time difference of arrival (UL-TDOA) and NR uplink angle of departure (UL-AD). Departure (UL-AoA); uplink and downlink hybrid positioning technologies include NR Multi-RTT, where the UE reports the UE transmit / receive time difference (UERx-Tx time difference) and the gNB reports the gNB transmit / receive time difference (gNB Rx-Tx time difference).

[0003] In the aforementioned positioning technologies, when the terminal (or base station) performs measurements, if the number of received signal resources is small or the beam transmitted by the base station (or terminal) is wide, the location information obtained by the positioning server based on the measurement results reported by the terminal (or base station) is not accurate enough. On the other hand, when the terminal (or base station) performs measurements, if the number of received signal resources is large or the beam of the base station (or terminal) is thin, the measurement complexity of the terminal (or base station) is high, and the reference signal resource overhead of the base station (or terminal) is also high.

Based on the first measurement result of the downlink positioning reference signal resources in the first resource set reported by the terminal, the server determines the first transmission direction of the downlink positioning reference signal resources in the second resource set. Then, the server sends a first message containing the first transmission direction to the base station and the terminal (or only to the base station). The base station transmits the downlink positioning reference signal resources in the second resource set to the terminal according to the first transmission direction. The terminal measures the downlink positioning reference signal resources in the second resource set to obtain a second measurement result and reports the second measurement result to the positioning server. The positioning server locates the terminal's position based on the second measurement result.

[0157] Alternatively, after receiving the first measurement result reported by the terminal, the positioning server directly sends the first measurement result to the base station. The base station determines the first transmission direction of the downlink positioning reference signal resources in the second resource set based on the first measurement result, and transmits the downlink positioning reference signal resources in the second resource set to the terminal based on the first transmission direction. The terminal measures the downlink positioning reference signal resources in the second resource set, obtains the second measurement result, and reports the second measurement result to the positioning server. The positioning server locates the terminal's position based on the second measurement result.

[0158] In other words, in this embodiment, the first transmission direction of the downlink positioning reference signal in the second resource set is determined by measuring the downlink positioning reference signal in the first resource set. Then, the terminal is located by measuring the downlink positioning reference signal resources in the second resource set transmitted based on the first transmission direction. Since the terminal still measures the downlink positioning reference signal transmitted by the base station in the original way, the measurement complexity of the terminal will not increase. At the same time, since the second measurement result referenced by the positioning server when performing the final positioning is the measurement result obtained by the terminal measuring multiple downlink positioning reference signal resources from the same transmission direction (transmitted in the first transmission direction), the second measurement result obtained by the terminal is more accurate, thereby effectively improving the positioning accuracy of the positioning server in locating the terminal.

[0185] To facilitate understanding, the technical background of the embodiments of the present invention will be introduced below.

[0186] Please see Figure 1 As shown, Figure 1 The figure illustrates the entities related to positioning in a 5G NR system. As shown, for 5G NR positioning, the entities involved include terminal 101, base stations (102a, 102b, and 102c as shown in the figure), and positioning server 103. The positioning service is also referred to as the Location Management Function (LMF) entity.

[0187] Based on the above system architecture, in conventional positioning technology, for downlink positioning technology, terminal 101 measures the PRS resources sent by base stations (102a, 102b, 102c) respectively. Each PRS resource is shaped into different directions (for example, it can also be called shaped into different beams) to obtain positioning measurement results and report them to positioning server 103. Based on the positioning measurement results reported by terminal 101 and the angle information of each PRS resource reported by base stations 102a, 102b and 102c, positioning server 103 determines the departure angle of the PRS resources sent by base stations 102a, 102b and 102c to terminal 101, and then determines the location information of terminal 101 based on the departure angle. Specifically, terminal 101 measures multiple beams transmitted by base stations 102a, 102b and 102c respectively, and feeds back the RSRP corresponding to each beam to positioning server 103. Positioning server 103 calculates the position of terminal 101 based on the RSRP fed back by terminal 101 and the transmission angle corresponding to each beam reported by base stations 102a, 102b and 102c using a position calculation algorithm.

[0188] For uplink positioning, base stations 102a, 102b, and 102c measure the SRS resources sent by terminal 101. Each SRS resource is shaped into different directions (e.g., different beams) to obtain positioning measurement results, which are then reported to positioning server 103. Based on the positioning measurement results reported by base stations 102a, 102b, and 102c and the transmission direction corresponding to each beam reported by terminal 101, positioning server 103 uses a position calculation algorithm to calculate the position of terminal 101.

[0189] Taking the downlink positioning technology DL-AoD as an example, the positioning server 103 calculates the terminal's location information by measuring the RSRP of the PRS resources reported by the terminal 101 and the transmission angle of the corresponding PRS resources reported by the base station. However, when the number of PRS resources transmitted by the base stations 102a, 102b and 102c is small or the beams transmitted by the base stations 102a, 102b and 102c are wide, the location of the terminal 101 calculated by the positioning server 103 using the location calculation algorithm is not accurate enough. When the number of PRS resources transmitted by the base stations 102a, 102b and 102c is large or the beams transmitted by the base stations 102a, 102b and 102c are thin, the complexity of the measurement by the terminal 101 will increase, and the reference signal resource overhead of the base stations 102a, 102b and 102c will also increase.

[0190] In view of this, the embodiments of this application provide a positioning method, which determines the first transmission direction of the downlink positioning reference signal in the second resource set by measuring the measurement result of the downlink positioning reference signal in the first resource set, and then positions the terminal by measuring the downlink positioning reference signal resources in the second resource set transmitted based on the first transmission direction. This method can improve positioning accuracy while ensuring measurement complexity.

[0191] In the downlink positioning method provided in this application embodiment, the base station transmits two levels of PRS resources (i.e., a first resource set and a second resource set) to the terminal. Please refer to [link to relevant documentation]. Figure 2 As shown, Figure 2 The diagram illustrates the transmission method of a base station for two-level PRS resources. It should be noted that the positioning method provided in this embodiment requires the participation of at least three base stations, and the transmission method of the other at least two base stations for the two-level PRS resources is different from... Figure 2 The method shown is the same.

[0192] Please see Figure 3 As shown, Figure 3 This is a flowchart illustrating a positioning method provided in an embodiment of this application. Figure 3 The steps of the method shown are as follows:

[0193] Step 301: The location server configures the first resource set and the second resource set for the terminal;

[0194] In this embodiment, the first resource set and the second resource set include multiple PRS resources. Each PRS resource in the first resource set, after shaping, corresponds to a direction. Different PRS resources correspond to different directions, and the direction corresponding to the PRS resource can be described by angle information, which may include at least one of horizontal and vertical angles. The first and second resource sets configured by the positioning server for the terminal are sent to the positioning server after being configured by the base station.

[0195] Step 302: The base station transmits PRS resources from the first resource set to the terminal, or transmits PRS resources from the first resource set and the second resource set to the terminal.

[0196] The base station can transmit PRS resources to the terminal in the following two ways:

[0197] Method 1: PRS resources in the first resource set are transmitted periodically, while PRS resources in the second resource set are transmitted non-periodically.

[0198] When the PRS in the second resource set is transmitted aperiodically, the transmission direction of the PRS resources in the second resource set can be determined based on the first measurement result of the terminal on the PRS resources in the first resource set. Therefore, when the PRS in the second resource set is transmitted aperiodically, the base station may not first shape the PRS resources in the second resource set (i.e., not specify the direction of the PRS resources in the second resource set) when transmitting the PRS resources in the first resource set.

[0199] Method 2: PRS resources in the first resource set are transmitted periodically, while PRS resources in the second resource set are transmitted non-periodically.

[0200] When the PRS resources in the second resource set are transmitted periodically, the transmission direction of the PRS resources in the second resource set is not determined based on the first measurement result of the terminal on the PRS resources in the first resource set. Therefore, when the PRS resources in the second resource set are transmitted periodically, the base station needs to determine the transmission direction of the PRS resources in the second resource set (i.e., it needs to shape the PRS resources in the second resource set) when shaping the PRS resources in the first resource set.

[0201] Step 303: The terminal measures the PRS resources in the first resource set, obtains the first measurement result, and reports the first measurement result to the positioning server;

[0202] In this embodiment of the application, regardless of whether the second resource set is transmitted periodically or aperiodically, the terminal only measures the PRS resources in the first resource set. After obtaining the first measurement result, the terminal reports the first measurement result to the positioning server. The first measurement result includes the RSRP of the PRS resources in the first resource set and the index of the PRS resources in the first resource set.

[0203] After the terminal reports the first measurement result to the positioning server, in one possible implementation, the positioning server can determine the first transmission direction itself, and in this case, step 304a is executed; in another possible implementation, the positioning server can also directly send the first measurement result to the base station so that the base station can determine the first transmission direction, and in this case, step 304b is executed.

[0204] Step 304a: The positioning server determines the first transmission direction of the PRS resources in the second resource set based on the first measurement result;

[0205] In this embodiment of the application, when the positioning server receives the first measurement result reported by the terminal, it determines the first PRS resource based on the first measurement result and determines the transmission direction corresponding to the first PRS resource as the first transmission direction. The first PRS resource is determined by the positioning server based on the RSRP in the first measurement result; preferably, the first PRS resource is the PRS resource with the highest RSRP in the first resource set.

[0206] In one possible implementation, after determining the first transmission direction, the positioning server may also send a first message to the base station (or simultaneously send a first message to both the terminal and the base station). The first message sent to the base station is used to instruct the base station to transmit PRS resources in the second resource set based on the first transmission direction; the first message sent to the terminal is used to inform the base station that the direction of transmitting PRS resources in the second resource set is the first transmission direction.

[0207] In one possible implementation, before sending the first message to the base station, the positioning server may first determine the content contained in the first message, which may include, for example, one of: a first transmission direction, a second QCL relationship, a first indication message, or an index of a second downlink positioning reference signal resource. Since the content contained in the first message may be related to whether the PRS resources in the second resource set are periodically transmitted or whether the PRS resources in the second resource set are configured with a first QCL relationship with the PRS resources in the first resource set, the positioning server may also determine whether the PRS resources in the second resource set are configured with a first QCL relationship with the PRS resources in the first resource set before determining the content of the first message.

[0208] Specifically, when the positioning server determines that the PRS resources in the second resource set are non-periodic transmissions and that the PRS resources in the second resource set are not configured with a first QCL relationship with the PRS resources in the first resource set, the positioning server can configure a second QCL relationship between the PRS resources in the second resource set and the first PRS resources according to the first transmission direction, and determine the second QCL relationship as the content of the first message; or, the positioning server can directly determine the first transmission direction as the content of the first message. It should be noted that after the positioning server configures the second QCL relationship for the PRS resources in the second resource set, the direction in which the base station transmits the PRS resources in the second resource set to the terminal based on the second QCL relationship is the first transmission direction.

[0209] When the positioning server determines that the PRS in the second resource set is a non-periodic transmission and that the PRS resource in the second resource set is configured with a first QCL relationship with the PRS resource in the first resource set, the positioning server can determine the second PRS resource corresponding to the first PRS resource from the second resource set based on the first measurement result and the first QCL relationship, and determine the index of the second PRS resource as the content of the first message.

[0210] When the positioning server determines that the second resource set is periodically transmitted and the PRS resources in the second resource set are not configured with the first QCL relationship with the PRS resources in the first resource set, the positioning server determines the first indication message as the content of the first message, which is used to instruct the base station to adjust the transmission direction of the PRS resources in the second resource set to the first transmission direction.

[0211] Step 304b: The positioning server sends the first measurement result to the base station, and the base station determines the first transmission direction of the PRS resource in the second resource set based on the first measurement result;

[0212] In this embodiment of the application, the process of the base station determining the first transmission direction is the same as the process of the positioning server determining the first transmission direction of the PRS resources in the second resource set in step 304a, and will not be described again here.

[0213] Step 305: The base station transmits the PRS resources of the second resource set to the terminal according to the first transmission direction;

[0214] In one possible implementation, the first transmission direction is determined by the positioning server and sent to the base station via a first message. When the base station determines that the content of the first message is the first transmission direction, it transmits the PRS resources in the second resource set to the terminal according to the first transmission direction. When the base station determines that the content of the first message is an index of the second downlink positioning reference signal resources, it transmits the second downlink positioning reference signal resources corresponding to the index to the terminal. When the base station determines that the content of the first message is a second QCL relationship, it transmits the PRS resources in the second resource set to the terminal according to the second QCL relationship. When the base station determines that the content of the first message is a first indication message, it adjusts the transmission direction of the downlink positioning reference signal resources in the second resource set to the first transmission direction and transmits them to the terminal.

[0215] In another possible implementation, the first transmission direction is determined by the base station based on the first measurement result. In this case, the base station transmits the PRS resources of the second resource set to the terminal according to the first transmission direction; or, transmits the second downlink positioning reference signal resources to the terminal; or, adjusts the transmission direction of the downlink positioning reference signal resources of the second resource set to the first transmission direction and transmits them to the terminal.

[0216] In one possible implementation, when the PRS resources in the second resource set are transmitted periodically, the base station transmits the PRS resources in the second resource set to the terminal based on the first transmission direction by transmitting the downlink positioning reference signal resources in the second resource set to the terminal according to the transmission period of the first transmission direction and the second resource set; when the PRS resources in the second resource set are transmitted periodically, after a preset duration for which the terminal reports the first measurement result, or after a preset duration for which the base station sends feedback information based on the terminal reporting the first measurement result to the terminal, the downlink positioning reference signal resources in the second resource set are transmitted to the terminal according to the first message; wherein, the preset duration is predefined by the system, or is the duration included in the signaling sent by the positioning server.

[0217] Step 306: The terminal measures the downlink positioning reference signal resources in the second resource set, obtains the second measurement result, and reports the second measurement result to the positioning server;

[0218] In this embodiment, after measuring the PRS resources in the second resource set, the terminal needs to report the corresponding parameters to the positioning server. Specifically, the terminal can measure the PRS resources according to the type of measurement result configured by the positioning server to obtain the corresponding type of measurement result. For example, the terminal can measure the PRS resources in the second resource set according to the configuration of the positioning server to obtain the RSTD or RSRP value corresponding to each PRS resource, and then report the corresponding parameters (i.e., the second measurement result) to the positioning server. The second measurement result includes: the RSTD or RSRP value corresponding to each PRS resource in the second resource set received by the terminal, and the index of the PRS resource.

[0219] Preferably, after obtaining the second measurement result, the terminal can also determine the third PRS resource based on the second measurement result, and report the index of the third resource and the corresponding RSRP or RSTD to the positioning server. The third PRS resource is, for example, the top M PRS resources in the second resource set with the strongest RSRP or the smallest RSTD.

[0220] Step 307: The positioning server locates the terminal's position based on the first measurement result.

[0221] In this embodiment, after receiving the first measurement result reported by the terminal, the positioning server can also send a first request to the base station to obtain the PRS angle information corresponding to the PRS resource. Specifically, the first request may be the positioning server instructing the base station to report the PRS angle information corresponding to all the PRS resources it has configured, or the positioning server instructing the base station to report the PRS angle information corresponding to all the PRS resources in the second resource set, or the PRS angle information corresponding to the second PRS resource, or the positioning server, after receiving the second measurement result reported by the terminal, instructing the base station to report the PRS angle information corresponding to the PRS resource index contained in the second measurement result reported by the terminal, based on the PRS resource information (such as the PRS resource index) included in the second measurement result reported by the terminal. After the base station reports the angle information, the positioning server uses a position calculation algorithm to calculate the terminal's position for the PRS angle information corresponding to the same resource index and the second measurement result, thereby achieving the location positioning of the terminal.

[0222] In some other embodiments, after obtaining the first measurement result, the terminal can also determine the first PRS resource based on the first measurement result and report the index of the first PRS resource to the positioning server. The positioning server determines the transmission direction of the first PRS resource as the first transmission direction and sends the first transmission direction to the base station, or configures a second QCL relationship for the PRS resources in the second resource set and sends the second QCL relationship to the base station, or sends the index of the first PRS resource to the base station so that the base station can determine the first transmission direction of the PRS resources in the second resource set based on the index. The method by which the terminal determines the first PRS resource is the same as the method by which the positioning server determines the first PRS resource, and will not be described again.

[0223] The above embodiments only illustrate the following three methods:

[0224] The first type: PRS resources in the first resource set are transmitted periodically, PRS resources in the second resource set are transmitted non-periodically, and the QCL relationship between PRS resources in the first resource set and PRS resources in the second resource set is not configured.

[0225] The second method involves periodic transmission of PRS resources in the first resource set and aperiodic transmission of PRS resources in the second resource set, with the QCL relationship configured between the PRS resources in the first and second resource sets.

[0226] The third type: PRS resources in the first resource set are transmitted periodically, PRS resources in the second resource set are transmitted periodically, and the QCL relationship between PRS resources in the first resource set and PRS resources in the second resource set is not configured.

[0227] In some other embodiments, the base station transmits PRS resources from the first resource set and the second resource set to the terminal in the following ways (i.e., the fourth case):

[0228] The PRS resources in the first resource set are transmitted periodically, and the PRS resources in the second resource set are transmitted periodically. The QCL relationship between the PRS resources in the first resource set and the PRS resources in the second resource set is configured.

[0229] For the fourth scenario, please refer to [link / reference]. Figure 4 As shown, Figure 4 This is a flowchart illustrating another positioning method provided in an embodiment of this application. Figure 4 The process steps shown are as follows:

[0230] Step 401: The location server configures the first resource set and the second resource set for the terminal;

[0231] In this embodiment, the first resource set and the second resource set include multiple PRS resources. Each PRS resource in the first resource set, after shaping, corresponds to a direction. Different PRS resources correspond to different directions, and the direction corresponding to the PRS resource can be described by angle information, which may include at least one of horizontal and vertical angles. The first and second resource sets configured by the positioning server for the terminal are sent to the positioning server after being configured by the base station.

[0232] Step 402: The base station transmits PRS resources from the first resource set and the second resource set to the terminal;

[0233] In this embodiment of the application, the base station transmits PRS resources in the first resource set and the second resource set to the terminal according to the PRS angle information (or transmission direction) corresponding to each PRS resource.

[0234] Step 403: The terminal measures the PRS resources in the first resource set and obtains the first measurement result;

[0235] Specifically, based on the relevant information of the first and second resource sets configured by the positioning server, the terminal measures only the PRS resources in the first resource set to obtain a first measurement result. It should be noted that after obtaining the first measurement result, the terminal can report it to the positioning server, or it can wait until it obtains the second measurement result and then report both the first and second measurement results simultaneously. In this embodiment, the time for the terminal to report the first and second measurement results is not limited. The first measurement result includes the RSRP of the PRS resources in the first resource set and the index of the PRS resources in the first resource set.

[0236] Step 404: The terminal measures the PRS resources in the second resource set according to the first measurement result, and obtains the second measurement result;

[0237] In this embodiment, the terminal determines a first PRS resource based on a first measurement result. The first PRS resource is determined by the positioning server based on the RSRP in the first measurement result; preferably, the first PRS resource is the PRS resource with the highest RSRP in the first resource set. After determining the first PRS resource, the terminal selects a second PRS resource from the PRS resources in the second resource set that has a QCL relationship with the first PRS resource, according to a first QCL relationship, and measures the second PRS resource to obtain a second measurement result. The second measurement result includes: the RSTD or RSRP value corresponding to the second PRS resource received by the terminal, and the index of the PRS resource.

[0238] Step 405: The terminal reports the first measurement result and the second measurement result to the positioning server;

[0239] In this embodiment, the terminal reports the index of the PRS resource in the first resource set and the corresponding RSRP value, as well as the RSTD or RSRP value of the second PRS resource in the second resource set and the index of the PRS resource to the positioning server. Preferably, the terminal only reports the index of the first PRS resource in the first resource set and the corresponding RSRP value to the positioning server.

[0240] Step 406: The positioning server sends a first request to the base station to obtain the PRS angle information corresponding to the PRS resource;

[0241] Specifically, the first request may be that the positioning server instructs the base station to report the PRS angle information corresponding to all the PRS resources it has configured, or the positioning server instructs the base station to report the PRS angle information corresponding to all the PRS resources in the second resource set, or the positioning server instructs the base station to report the PRS angle information corresponding to the second PRS resource index, or the positioning server, after receiving the second measurement result reported by the terminal, instructs the base station to report the PRS angle information corresponding to the PRS resource index contained in the second measurement result reported by the terminal.

[0242] Step 407: The base station reports the angle information of the PRS resource to the positioning server according to the first request;

[0243] Step 408: The positioning server locates the terminal's position based on the first measurement result, the second measurement result, and the angle information reported by the base station.

[0244] In this embodiment, the positioning server essentially locates the terminal's position based on the second measurement result and angle information during the positioning process. Specifically, if the base station reports PRS angle information corresponding to all its configured PRS resources, or PRS angle information corresponding to all PRS resources in the second resource set, or PRS angle information corresponding to the second PRS resource index in step 606, the positioning server selects the PRS angle information of the PRS resource corresponding to the PRS resource index in the second measurement result from all the PRS resources, or the PRS resources in the second resource set, or the second PRS resources. The positioning server then uses a position calculation algorithm to calculate the terminal's position based on the PRS angle information corresponding to the same resource index and the second measurement result, thereby achieving the positioning of the terminal.

[0245] In some embodiments, after obtaining the second measurement result, the terminal can further determine a third PRS resource based on the second measurement result, and report the index of the third resource and the corresponding RSRP or RSTD to the positioning server. The third PRS resource is, for example, the PRS resource with the strongest RSRP or the smallest RSTD among the second PRS resources.

[0246] To better understand the technical solution of this application, the information processing method provided in this application will be explained and described below with reference to specific embodiments.

[0247] Example 1: The first resource set is transmitted periodically, and the second resource set is transmitted aperiodically. The first resource set contains N PRS resources, and each PRS resource is configured with a QCL with the SSB. The second resource set contains M PRS resources, and the PRS resources in the M PRS resources are not configured with a first QCL relationship.

[0248] Step 1: The base station sends N PRS resources in the first resource set. The terminal measures the N PRS resources, obtains the first measurement result, and reports the first measurement result to the positioning server. The first measurement result includes the index of the N PRS resources and the corresponding RSRP result. Alternatively, the terminal can also determine the PRS resource with the largest RSRP in the first resource set based on the first measurement result and report the index of the PRS resource with the largest RSRP to the positioning server.

[0249] Step 2: The positioning server determines the first transmission direction (e.g., the transmission direction corresponding to the PRS resource with the largest RSRP) of the M PRS resources in the second resource set based on the first measurement result reported by the terminal or the index of the PRS resource with the largest RSRP, and informs the base station of the first transmission direction, or it can inform both the base station and the terminal; or, the positioning server configures the second QCL relationship for the M PRS resources in the second resource set based on the first transmission direction, and informs the base station of the QCL relationship, or it can inform both the base station and the terminal; or, the positioning server directly informs the base station of the first measurement result, and the base station determines the first transmission direction of the M PRS resources in the second resource set based on the first measurement result; wherein, the positioning server informs the base station of the first transmission direction, the second QCL relationship, or the first measurement result by sending a first message containing the aforementioned content to the base station, for example;

[0250] Step 3: The base station transmits M PRS resources in the second resource set to the terminal after a preset time (e.g., time T) according to the first transmission direction indicated by the positioning server, or the second QCL relationship configured by the positioning server, or the first transmission direction determined by itself based on the first measurement result; or it can inform the terminal of the first transmission direction or the second QCL relationship.

[0251] Step 4: The terminal receives M PRS resources from the second resource set. At this point, the terminal can assume the base station will transmit in the direction corresponding to the PRS resource with the strongest RSRP in the first resource set; that is, the terminal receives the M PRS resources from the second resource set according to the direction corresponding to the PRS resource with the strongest RSRP in the first resource set. Alternatively, the terminal receives the M PRS resources from the second resource set according to the first transmission direction or the second QCL relationship provided by the base station or positioning server.

[0252] Step 5: The terminal measures the M PRS resources in the second resource set, obtains the second measurement result, and reports the second measurement result to the positioning server; the second measurement result includes the index of the M PRS resources and the corresponding RSTD result or RSRP result; or, the terminal can also determine the L PRS resources with the largest RSRP or smallest RSTD among the M PRS resources in the second resource set according to the second measurement result, and report the index of the L PRS resources with the largest RSRP or smallest RSTD and the corresponding RSRP or RSTD to the positioning server, where L is less than M;

[0253] Step 6: The positioning server sends a first request to the base station to obtain the PRS angle information corresponding to the PRS resources in the second resource set;

[0254] Step 7: The base station reports the PRS angle information corresponding to the PRS resources in the second resource set to the positioning server.

[0255] Step 8: The positioning server locates the terminal's position based on the second measurement result and the angle information reported by the base station.

[0256] Example 2: The first resource set is transmitted periodically, and the second resource set is transmitted aperiodically. The first resource set contains N PRS resources, and each PRS resource is configured with a QCL with an SSB. The second resource set contains N×M PRS resources, and each M PRS resource in the second resource set is configured with a first QCL relationship with one PRS resource in the first resource set.

[0257] Step 1: The base station sends N PRS resources in the first resource set, and the terminal measures the N PRS resources to obtain the first measurement result;

[0258] Step 2: The terminal reports the first measurement result to the positioning server (for example, after sorting the RSRPs in descending order, the indexes of the top K PRS resources and their corresponding RSRP values ​​are reported to the positioning server, where K is an integer greater than or equal to 1).

[0259] Step 3: The positioning server determines the first PRS resource (e.g., the PRS resource with the highest RSRP) based on the first measurement result. The positioning server selects M PRS resources corresponding to the first PRS resource from the second resource set according to the first QCL relationship (i.e., selects M PRS resources with QCL corresponding to the first PRS resource), and informs the base station of the index of the M PRS resources. Alternatively, the positioning server can inform both the base station and the terminal. Or, the positioning server can directly inform the base station of the index of the first PRS resource, or inform both the base station and the terminal, so that the base station can select M PRS resources corresponding to the first PRS resource from the second resource set according to the first QCL relationship (i.e., selects M PRS resources with QCL corresponding to the first PRS resource). The positioning server informs the base station of the index of the M PRS resources or the index of the first PRS resource by sending a first message containing the aforementioned content to the base station, for example.

[0260] Step 4: The base station transmits the M PRS resources corresponding to the second PRS resource in the second resource set to the terminal. Alternatively, it can inform the terminal of the index of the M PRS resources or the index of the first PRS resource.

[0261] Step 5: The terminal receives the M PRS resources corresponding to the second PRS resource. At this point, the terminal can assume that the base station will transmit in the direction corresponding to the PRS resource with the strongest RSRP in the first resource set; that is, the terminal receives the M PRS resources in the second resource set according to the direction corresponding to the PRS resource with the strongest RSRP in the first resource set. Alternatively, the terminal receives the M PRS resources in the second resource set based on the index of the M PRS resources or the index of the first PRS resource provided by the base station or positioning server, and on the QCL relationship corresponding to the index.

[0262] Step 6: The terminal measures the M PRS resources to obtain a second measurement result, and reports the second measurement result to the positioning server; the second measurement result includes the index of the M PRS resources and the corresponding RSTD result or RSRP result; or, the terminal can also determine the L PRS resources with the largest RSRP or smallest RSTD among the M PRS resources in the second resource set according to the second measurement result, and report the index of the L PRS resources with the largest RSRP or smallest RSTD and the corresponding RSRP or RSTD to the positioning server, where L is less than M;

[0263] Step 7: The positioning server sends a first request to the base station to obtain the PRS angle information corresponding to the PRS resources in the second resource set;

[0264] Step 8: The base station reports the PRS angle information corresponding to the PRS resources in the second resource set to the positioning server.

[0265] Step 9: The positioning server locates the terminal's position based on the second measurement result and the angle information reported by the base station.

[0266] Example 3: The first resource set is transmitted periodically, and the second resource set is transmitted periodically. The first resource set contains N PRS resources, and each PRS resource is configured with a QCL with the SSB. The second resource set contains M PRS resources, and the PRS resources in the M PRS resources are not configured with a first QCL relationship.

[0267] Step 1: The base station sends N PRS resources in the first resource set and M PRS resources in the second resource set. The terminal measures the N PRS resources, obtains the first measurement result, and reports the first measurement result to the positioning server. The first measurement result includes the index of the N PRS resources and the corresponding RSRP result, or the index of the K PRS resources with the highest RSRP ranking and the corresponding RSRP result.

[0268] Step 2: Based on the first measurement result reported by the terminal, the positioning server determines the first transmission direction of the M PRS resources in the second resource set (the first transmission direction is, for example, the transmission direction corresponding to the PRS resource with the largest RSRP in the first resource set), and informs the base station of the first transmission direction, or informs both the base station and the terminal; or, the positioning server directly informs the base station of the first measurement result, and the base station determines the first transmission direction of the M PRS resources in the second resource set based on the first measurement result, or informs the terminal of this first transmission direction. The positioning server informs the base station of the first transmission direction or the first measurement result by sending a first message containing the aforementioned content to the base station, for example.

[0269] Step 3: The base station adjusts the transmission direction of the M PRS resources in the second resource set to the first transmission direction and transmits it to the terminal;

[0270] Step 4: The terminal receives M PRS resources from the second resource set. At this point, the terminal can assume that the base station will use the direction corresponding to the PRS resource with the strongest RSRP in the first resource set for transmission. Alternatively, the terminal can receive a first transmission direction from the base station or positioning server and receive the M PRS resources from the second resource set based on this direction.

[0271] Step 5: The terminal measures the M PRS resources in the second resource set, obtains the second measurement result, and reports the second measurement result to the positioning server; the second measurement result includes the index of the M PRS resources and the corresponding RSTD result or RSRP result; or, the terminal can also determine the L PRS resources with the largest RSRP or smallest RSTD among the M PRS resources in the second resource set according to the second measurement result, and report the index of the L PRS resources with the largest RSRP or smallest RSTD and the corresponding RSRP or RSTD to the positioning server, where L is less than M;

[0272] Step 6: The positioning server sends a first request to the base station to obtain the PRS angle information corresponding to the PRS resources in the second resource set;

[0273] Step 7: The base station reports the PRS angle information corresponding to the PRS resources in the second resource set to the positioning server.

[0274] Step 8: The positioning server locates the terminal's position based on the second measurement result and the angle information reported by the base station.

[0275] Example 4: The first resource set is transmitted periodically, and the second resource set is transmitted periodically. The first resource set contains N PRS resources, and each PRS resource is configured with a QCL with an SSB. The second resource set contains N×M PRS resources, and each M PRS resource in the second resource set is configured with a first QCL relationship with one PRS resource in the first resource set.

[0276] Step 1: The base station sends N PRS resources in the first resource set and N×M PRS resources in the second resource set. The terminal measures the N PRS resources in the first resource set and obtains the first measurement result.

[0277] Step 2: The terminal determines the first PRS resource (e.g., the PRS resource with the largest RSRP in the first resource set) based on the first measurement result, and determines M PRS resources with the first QCL relationship from the second resource set based on the first QCL relationship;

[0278] Step 3: The terminal measures the M PRS resources to obtain a second measurement result, and reports the second measurement result and the first measurement result to the positioning server. The first measurement result may only include the index of the first PRS resource and its corresponding RSRP, while the second measurement result may include the indexes of the M PRS resources and their corresponding RSTD or RSRP results. Alternatively, the terminal may determine, based on the second measurement result, the L PRS resources with the largest RSRP or smallest RSTD among the M PRS resources in the second resource set, and report the indexes of these L PRS resources with the largest RSRP or smallest RSTD and their corresponding RSRP or RSTD to the positioning server, where L is less than M.

[0279] Step 4: The positioning server sends a first request to the base station to obtain the PRS angle information corresponding to the second PRS resource;

[0280] Step 5: The base station reports the PRS angle information corresponding to the second PRS resource to the positioning server;

[0281] Step 6: The positioning server locates the terminal's position based on the second measurement result and the angle information reported by the base station.
