[0002] With the rapid development of network technology, the number of users accessing the network is increasing. In order to provide services to users more accurately, it is necessary to locate the terminal. In actual application, the location management function (LMF) entity can request the base station to send the configuration information of the detection positioning signal to the terminal. When the LMF entity triggers the measurement request, the base station can receive the measurement results of the detection positioning signal sent by the terminal and report it to the LMF entity. The LMF entity locates the terminal based on the measurement results. In this process, when the base station receives the measurement results of the detection positioning signal sent by multiple terminals, there may be a conflict in the resources used by the measurement results of the detection positioning signal sent by multiple terminals, resulting in the LMF entity being unable to achieve accurate positioning.

[0087] Before introducing the technical solution of the embodiment of the present invention, the related technology is first described.

[0088] In the related technology, NR R16 supports obtaining the terminal's positioning information by sending and receiving reference signals. For example, the Observed Time Difference of Arrival (OTDOA) positioning technology is that the terminal receives downlink reference signals sent by multiple base stations, and calculates the terminal's location information using the arrival time difference of reference signals from different base stations; the uplink time difference of arrival (UTDOA) positioning technology is that multiple base stations receive uplink reference signals sent by the terminal, and calculates the terminal's location information using the time difference when the uplink reference signals arrive at different base stations. The uplink sounding reference signal (SRS) in R16 can be used for air interface positioning of user equipment (UE).

[0089] Figure 1 It is a schematic diagram of the implementation process of configuring the detection positioning signal by the base station in the related technology, such as Figure 1 As shown, including:

[0090] Step 0: The LMF entity requests and obtains TRP information.

[0091] Step 1: The LMF entity requests UE capabilities (by LPP).

[0092] Step 2-4: The LMF entity requests the UE's SRS configuration from the serving gNB; the gNB determines the configuration and sends it to the UE and reports it to the LMF entity;

[0093] Here, when requesting the SRS configuration of the UE, the LMF entity may carry the recommended configuration information, such as Figure 2 As shown. The gNB will refer to the recommended configuration sent by the LMF entity and determine the final UE SRS configuration based on the actual scheduling situation; the gNB sends the SRS configuration to the UE and reports it to the LMF entity.

[0094] Step 5: The LMF entity sends a request to activate / deactivate the UE's SRS configuration; the gNB uses MAC-CE to activate / deactivate the UE's SRS configuration;

[0095] Step 6-8: The LMF entity initiates a measurement request; the gNB / TRP performs UL SRS measurement and reports the measurement result to the LMF entity;

[0096] Here, when initiating a measurement request, the LMF entity sends the complete UE SRS configuration related information to the gNB / TRP to be measured, such as Figure 3 shown.

[0097] Here, the gNB / TRP selected for measurement performs the measurement and reports the measurement result. Here, the measurement result reported by the gNB / TRP to the LMF entity is as follows: Figure 4 shown.

[0098] In summary, in the related art, each base station can refer to the recommended configuration of the LMF entity to configure the resources used by the UE to send the SRS Pos for positioning, and report the configuration to the LMF entity. Figure 1 In step 6), the neighboring gNBs / TRPs to be measured receive the measurement results of the SRS Pos sent by the terminal according to the SRS PoS configuration information, and report the measurement results to the LMF entity. Since there is no coordination mechanism between the LMF entity and the base station, it is difficult to avoid conflicts in the resource configurations used by different terminals to report SRS PoS, thereby affecting the positioning accuracy. For example, assuming that the resource configuration used by a UE in the serving cell A to send SRS pos is SRS pos A, and the resource configuration used by the neighboring UE to send SRS pos to the serving cell A is also SRS pos A. It can be seen that the resource configuration used by the UE in this cell and the neighboring UE to send SRS pos to the serving cell A conflicts. For another example, the resource configuration used by cell A (cellA) to send SRS pos for UE_A of the cell is SRS pos A, and the resource configuration used by cell B (cell B) to send SRS pos for UE_B of the cell is SRS pos B. Both cells are close to (towards) a neighboring cell, namely cell C (cell C). Since SRS pos A and SRS pos B use the same time-frequency code resources, the two interfere with each other.

[0099] Based on this, in each embodiment of the present invention, the resources used by each terminal corresponding to each target cell to send the detection and positioning signal are configured to be orthogonal; the target cell is a cell that receives the detection and positioning signal; and the configuration information of the detection and positioning signal corresponding to each terminal is determined.

[0100] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.

[0101] The embodiment of the present invention provides a resource configuration method, which is applied to LMF entities, such as Figure 5 As shown, the method includes:

[0102] Step 501: configuring resources used by each terminal corresponding to each target cell to send a detection and positioning signal to be orthogonal; the target cell is a cell that receives the detection and positioning signal;

[0103] Step 502: Determine the configuration information of the detection and positioning signal corresponding to each terminal.

[0104] Here, in step 501, the LMF entity may have a coordination function, that is, the LMF entity may configure the resources used by each terminal corresponding to each target cell to send a detection positioning signal. In actual application, the LMF entity may configure multiple cells under its jurisdiction into at least one cell group, and configure the resources used by multiple terminals in each target cell in the same cell group to send detection positioning signals to be orthogonal, and / or, configure the resources used by each terminal in different target cells corresponding to different cell groups to send detection positioning signals to be orthogonal. In this way, the problem that the LMF entity cannot accurately locate due to the conflict of resources used by multiple terminals to send detection positioning signals in the related technology can be avoided. Among them, the detection positioning signal may refer to a detection reference signal used for positioning.

[0105] Here, in step 502, the LMF entity can also configure the configuration information of the detection and positioning signal for multiple terminals of each target cell, and send it to the served terminals through the base station located in the service cell. The terminal completes the measurement of the detection and positioning signal and reports the measurement results according to the received configuration information.

[0106] It should be noted that in an embodiment of the present invention, the LMF entity can configure the resources used by each terminal corresponding to each target cell in the same cell group to send a detection and positioning signal to be orthogonal, and can also configure the resources used by each terminal in different target cells corresponding to different cell groups to send a detection and positioning signal to be orthogonal.

[0107] The following describes in detail the process of how the LMF entity configures the resources used by each terminal corresponding to each target cell in the same cell group to send a detection positioning signal to be orthogonal.

[0108] In actual application, before the LMF entity configures the resources used by each terminal corresponding to each target cell in the same cell group to send the detection positioning signal to be orthogonal, multiple cells under its jurisdiction can be divided into at least one cell group, and each cell group can include at least one target cell.

[0109] Based on this, in one embodiment, configuring the resources used by each terminal corresponding to each target cell to send a detection positioning signal to be orthogonal includes:

[0110] Divide at least two cells under the jurisdiction of the LMF entity into at least one cell group;

[0111] The resources used by each terminal corresponding to each target cell in the same cell group to send a detection and positioning signal are configured to be orthogonal.

[0112] For example, as shown in Table 1, the LMF entity may divide cell 1, cell 2, cell 3, and cell 4 within its jurisdiction into a cell group, and the target cell is divided into cell 1, cell 2, cell 3, and cell 4; or, divide cell 3 within its jurisdiction into a cell group, and the target cell is divided into cell 3; or, divide cell 4 and cell 5 within its jurisdiction into a cell group, and the target cell is divided into cell 4 and cell 5; or, divide cell 6, cell 7, and cell 8 within its jurisdiction into a cell group; and the target cell is divided into cell 6, cell 7, and cell 8.

[0113] Cell group number Target cells included in the cell group Cell Group 1 Community 1, Community 2, Community 3, Community 4 Cell Group 2 Cell 3 Cell Group 3 Community 4, Community 5 Cell Group 4 Community 6, Community 7, Community 8

[0114] Table 1

[0115] In actual application, when the target cell serves as a service cell, it can receive detection and positioning signals sent by at least two terminals of the service cell; when the target cell serves as a neighboring cell of the service cell, it can receive detection and positioning signals sent by at least two terminals of other service cells.

[0116] Based on this, in one embodiment, the detection and positioning signal is sent to the target cell by at least two terminals of the target cell as a serving cell; or, the detection and positioning signal is sent to the target cell by at least two terminals of the target cell as a neighboring area of ​​the serving cell; or, the detection and positioning signal is sent to the target cell by at least one terminal of the target cell as a serving cell and at least one terminal of the target cell as a neighboring area of ​​the serving cell.

[0117] Table 2 is a schematic diagram of the target cell and the corresponding terminals that send detection positioning signals. As shown in Table 2, a cell group includes target cell 1, target cell 2, target cell 3, and target cell 4; the detection positioning signal received by the base station gNB1 of the target cell 1 is sent by UE11, UE12 of the target cell 1 as the service cell and UE31 of the target cell 1 as the neighboring cell of the service cell; the detection positioning signal received by the base station gNB2 of the target cell 2 is sent by UE21, UE22 of the target cell 2 as the service cell and UE42 of the target cell 2 as the neighboring cell of the service cell; the detection positioning signal received by the base station gNB3 of the target cell 3 is sent by UE11, UE12, and UE41 of the target cell 3 as the neighboring cell of the service cell; the detection positioning signal received by the base station gNB4 of the target cell 4 is sent by UE41 and UE42 of the target cell 4 as the service cell.

[0118]

[0119] Table 2

[0120] In actual application, in order to avoid the problem in the related technology that the LMF entity cannot accurately locate due to the conflict of resources used by multiple terminals to send detection and positioning signals, the resources used by the terminals in the target cell as the service cell and / or the terminals in the neighboring cells of the service cell to send detection and positioning signals can be configured to be orthogonal.

[0121] Based on this, in one embodiment, configuring the resources used by each terminal corresponding to each target cell to send the detection positioning signal to be orthogonal includes at least one of the following:

[0122] The resources used by each terminal in the target cell as a serving cell to send a detection and positioning signal are configured to be orthogonal;

[0123] The target cell is used as a resource configuration for each terminal in the neighboring area of ​​the serving cell to send the detection positioning signal to be orthogonal;

[0124] The resources used by each terminal in which the target cell is used as a serving cell and each terminal in a neighboring cell in which the target cell is used as a serving cell to send a detection and positioning signal are configured to be orthogonal.

[0125] Here, the resource includes at least one of the following:

[0126] Time domain resources, frequency domain resources, and code domain resources.

[0127] Here, if the LMF entity divides at least two cells under its jurisdiction into at least one cell group, the resources used by each terminal corresponding to each target cell in the same cell group to send a detection positioning signal can be configured to be orthogonal.

[0128] In actual application, it is taken into account that the resources used by the terminal to send the detection and positioning signal may be time domain resources, frequency domain resources, etc., so when the resources used by the terminal to send the detection and positioning signal to the target cell are time domain resources, the orthogonality of the time domain resources can be achieved through time division multiplexing; when the resources used by the terminal to send the detection and positioning signal to the target cell are frequency domain resources, the orthogonality of the frequency domain resources can be achieved through frequency division multiplexing; when the resources used by the terminal to send the detection and positioning signal to the target cell are code domain resources, the orthogonality of the frequency domain resources can be achieved through code division multiplexing.

[0129] Based on this, in one embodiment, the manner of configuring orthogonality includes one of the following:

[0130] Orthogonality is achieved through time division multiplexing;

[0131] Orthogonality is achieved through frequency division multiplexing;

[0132] Orthogonality is achieved through code division multiplexing;

[0133] Orthogonality is achieved by combining at least two of time division multiplexing, frequency division multiplexing, and code division multiplexing.

[0134] Here, orthogonality is achieved through frequency division multiplexing, including:

[0135] Orthogonality is achieved through different activation BWPs or different frequency domain combs;

[0136] Here, orthogonality is achieved through code division multiplexing, including:

[0137] Orthogonality is achieved through different cyclic shifts.

[0138] For example, Figure 6 It is a schematic diagram of the cell group, target cell, and terminal, such as Figure 6 As shown, a cell group includes 4 cells. The resource configuration used by each terminal corresponding to each target cell in the same cell group to send a detection positioning signal is orthogonal, and the specific process is as follows:

[0139] For the target cell 1, it is assumed that the detection positioning signal received by the base station gNB1 of the target cell 1 is sent by UE11, UE12 of the target cell 1 as the service cell and UE31 of the neighboring cell of the target cell 1 as the service cell, wherein the sending of the detection positioning signal by UE11 to gNB1 can be represented by UE11->gNB1, the sending of the detection positioning signal by UE12 to gNB1 can be represented by UE12->gNB1, and the sending of the detection positioning signal by UE31 to gNB1 can be represented by UE31->gNB1. Then the LMF entity can configure the resources used by UE11, UE12, and UE31 corresponding to the target cell 1 in the cell group to send the uplink detection positioning signal (UL SRS pos) as orthogonal, such as time domain / frequency domain / code domain resource orthogonality, as shown in Table 3.

[0140] For the target cell 2, it is assumed that the detection positioning signal received by the base station gNB2 of the target cell 2 is sent by UE21, UE22 of the target cell 2 as the service cell and UE42 of the neighboring cell of the target cell 2 as the service cell, wherein the detection positioning signal sent by UE21 to gNB2 can be represented by UE21->gNB2, the detection positioning signal sent by UE22 to gNB2 can be represented by UE22->gNB2, and the detection positioning signal sent by UE42 to gNB2 can be represented by UE42->gNB2. The LMF entity can configure the resources used by UE21, UE22, and UE42 corresponding to the target cell 2 in the cell group to send the uplink detection positioning signal (UL SRS pos) to be orthogonal, such as time domain / frequency domain / code domain resources are orthogonal, as shown in Table 3.

[0141] For the target cell 3, it is assumed that the detection positioning signal received by the base station gNB3 of the target cell 3 is sent by UE31, UE32 of the target cell 3 as the service cell and UE11, UE12, and U41 of the neighboring cell of the target cell 3 as the service cell, wherein the detection positioning signal sent by UE31 to gNB3 can be represented by UE31->gNB3, the detection positioning signal sent by UE32 to gNB3 can be represented by UE32->gNB3, the detection positioning signal sent by UE11 to gNB3 can be represented by UE11->gNB3, the detection positioning signal sent by UE12 to gNB3 can be represented by UE12->gNB3, and the detection positioning signal sent by UE41 to gNB3 can be represented by UE41->gNB3. Then the LMF entity can configure the resources used by UE11, UE12, UE31, UE32, and U41 corresponding to the target cell 3 in the cell group to send the uplink detection positioning signal (UL SRS pos) as orthogonal, such as time domain / frequency domain / code domain resources are orthogonal, as shown in Table 3.

[0142] For the target cell 4, it is assumed that the detection and positioning signal received by the base station gNB4 of the target cell 4 is sent by UE41, UE42 of the target cell 4 as the service cell and UE21, UE22, UE31, UE32 of the target cell 4 as the neighboring cell of the service cell, wherein the detection and positioning signal sent by UE41 to gNB4 can be represented by UE41->gNB4, the detection and positioning signal sent by UE42 to gNB4 can be represented by UE42->gNB4, the detection and positioning signal sent by UE21 to gNB4 can be represented by UE21->gNB4, the detection and positioning signal sent by UE22 to gNB4 can be represented by UE22->gNB4, the detection and positioning signal sent by UE31 to gNB4 can be represented by UE31->gNB4, and the detection and positioning signal sent by UE32 to gNB4 can be represented by UE32->gNB4. Then the LMF entity can send the uplink detection and positioning signal (UL SRS) to UE21, UE22, UE31, UE32, UE41, UE42 corresponding to the target cell 4 in the cell group The resource configuration used by pos) is orthogonal, such as time domain / frequency domain / code domain resources are orthogonal, as shown in Table 3.

[0143]

[0144] Table 3

[0145] In actual application, after the LMF entity determines the configuration information of the detection positioning signal for each terminal of each target cell in the same cell group, it can be sent to the corresponding terminal for each terminal of the target cell as a service cell through the base station corresponding to the service cell. For each terminal in the neighboring area of ​​the target cell as a service cell, it can be sent to the corresponding terminal through the base station serving the terminal.

[0146] Based on this, in one embodiment, the method further includes:

[0147] Sending the configuration information of the detection positioning signal to the base station to which the serving cell corresponding to each terminal belongs;

[0148] The configuration information of the detection positioning signal is used by the base station to send to the served terminal.

[0166]

[0167] Table 7

[0168] In actual application, after the LMF entity configures the resources used by each terminal corresponding to each target cell to send the detection and positioning signal to be orthogonal, it can also configure the corresponding configuration information of the detection and positioning signal for each terminal.

[0169] Based on this, in one embodiment, the configuration information for detecting the positioning signal includes:

[0170] Resource allocation information;

[0171] Path loss reference information;

[0172] Spatial correlation information;

[0173] Among them, the resource configuration information is used to characterize the orthogonality of the resources used by each terminal corresponding to each target cell to send the detection and positioning signal; the path loss reference signal is used to calculate the uplink transmission power of the detection and positioning signal sent by each terminal served by each target cell; the spatial correlation information is used to determine the uplink transmission beam used by each terminal served by each target cell to send the detection and positioning signal.

[0174] Here, the configuration information of the detection positioning signal includes but is not limited to: path loss reference information (pathlossreference) relative to the serving cell (serving cell) and neighboring cells (neighoring cells) of the terminal, spatial correlation information (spatial relation info), etc.

[0175] In one example, if Figure 7 As shown, the process of configuring the resources used by each terminal corresponding to each target cell in the same cell group to send a detection positioning signal to be orthogonal by the LMF entity is described, including:

[0176] Step 701: The resources used by the LMF entity to send uplink detection and positioning signals to each terminal in each target cell in the same cell group are configured to be orthogonal.

[0177] Specifically, the process of the LMF entity coordinating and configuring the resources used by each terminal in each target cell in the same cell group to send an uplink sounding positioning signal (SRS pos) includes:

[0178] Step 1: The LMF entity requests and obtains the information of all TRPs or gNBs in the same cell group and the capability information of the UE.

[0179] Here, the LMF entity can request and obtain the information of all TRPs or gNBs in the same cell group and the capability information of the UE based on the LPP protocol.

[0180] Step 2: The LMF entity coordinates and configures the resources used by each terminal in each target cell in the same cell group to send an uplink sounding positioning signal (SRS pos) to be orthogonal in the time / frequency / code resource domain.

[0181] The uplink sounding positioning signal (UL SRS pos) associated with the target cell (target cell) may be sent by a UE of which the target cell serves as a serving cell, or may be sent by a UE of a neighboring cell of which the target cell serves as a neighboring cell.

[0182] Here, time domain resource orthogonality may refer to resource orthogonality achieved through time division multiplexing such as SRS resource set and SRS resource; frequency domain resource orthogonality may refer to resource orthogonality achieved through frequency division multiplexing such as using different active BWPs or different frequency domain combs; code domain resource orthogonality may refer to resource orthogonality achieved through using different cyclic shifts.

[0183] Here, the UL SRS pos resources associated with different target cells in the same cell group do not need to be configured to be orthogonal in time / frequency / code resources.

[0184] Step 3: LMF determines the configuration information of the detection and positioning signal of each UE corresponding to each target cell in the same group in combination with the configuration principle of the detection and positioning signal (SRS Pos).

[0185] Here, the configuration information includes: pathloss reference and spatial relation info of a serving cell associated with the terminal, and pathloss reference and spatial relation info of a neigboring cell associated with the terminal.

[0186] Step 702: The LMF entity performs resource configuration based on the serving cells in the same cell group.

[0187] Specifically, after the LMF entity coordinates the configuration of resources used by each terminal in each target cell in the same cell group to send uplink detection and positioning signals, it recommends the SRS pos resource configuration of one or more UEs served by the same service cell to the service cell, which is then scheduled to the one or more UEs served.

[0188] Here, the LMF entity configures the resources used by each terminal corresponding to each target cell in the same cell group to send a detection positioning signal to be orthogonal, which has the following advantages:

[0189] (1) The LMF entity has a coordination function, that is, the LMF entity can configure multiple cells under its jurisdiction into at least one group, each group including at least one target cell; and can configure the resources used by multiple terminals in each target cell in the same cell group to send detection and positioning signals to be orthogonal to avoid resource interference. In this way, the problem that the LMF entity cannot accurately locate due to the conflict of resources used by multiple terminals to send detection and positioning signals in the related art can be avoided.

[0190] (2) A method for configuring resources used by multiple terminals in each target cell in the same cell group to send detection and positioning signals is provided.

[0191] (3) For the R17 indoor factory scenario, considering the limited number of gNB / TRPs in a typical factory, LMF can configure the resource configuration used by the UE under each gNB / TRP in the factory area to send the detection positioning signal (SRS pos) to be orthogonal.

[0192] (4) The resources used by multiple terminals in different target cells within the same cell group to send detection and positioning signals do not need to be configured to be orthogonal, which can improve the utilization rate of the resources required for sending the detection and positioning signals.

[0193] The following describes in detail the process of how the LMF entity configures the resources used by the terminals corresponding to different cell groups to send detection positioning signals to be orthogonal.

[0194] In actual application, in order to avoid the problem in the related technology that the LMF entity cannot accurately locate due to the resource conflict used by multiple terminals to send detection and positioning signals, for each target cell in different cell groups, the resources used by each terminal of the target cell as a service cell and / or each terminal in the neighboring area of ​​the service cell to send detection and positioning signals can be configured to be orthogonal.

[0195] Based on this, in one embodiment, the method further includes:

[0196] The resources used by the terminals corresponding to different cell groups to send detection and positioning signals are configured to be orthogonal.

[0197] In actual application, different beam resources, different sub-resource pools, and spatial isolation that meets a threshold can be used to achieve orthogonality of resources used by terminals corresponding to different cell groups to send detection and positioning signals.

[0198] Based on this, in one embodiment, configuring the resources used by the terminals corresponding to different cell groups to send the detection and positioning signals to be orthogonal includes one of the following:

[0199] The resources used by the terminals corresponding to different cell groups to send detection and positioning signals are configured as different spatial resources to achieve orthogonality, and the spatial resources include: beam resources;

[0200] The resources used by the terminals corresponding to different cell groups to send detection and positioning signals are configured as different sub-resource pools to achieve orthogonality, and the sub-resource pools include: time domain, frequency domain, and code domain sub-resource pools;

[0201] Orthogonality is achieved when the spatial isolation between resources used by terminals corresponding to different cell groups to send detection and positioning signals is greater than or equal to a threshold.

[0202] For example, Figure 8 is a schematic diagram of multiple cell groups, such as Figure 8 As shown, multiple cell groups are represented by Cell Group 1 (Cell Group 1), Cell Group 2 (Cell Group 2), and Cell Group 3 (Cell Group 3). The LMF entity configures the resources used by each terminal corresponding to different cell groups to send a detection positioning signal (SRS POS) as an orthogonal process, which is as follows:

[0203] In a first manner, the resources used by terminals corresponding to different cell groups to send sounding and positioning signals (SRS POS) may be configured as different beam resources to avoid interference through spatial beam coordination, wherein the beam resources may be narrow beams.

[0204] In the second method, LMF pre-configures different sub-resource pools (sub-resource pools) corresponding to different cell groups and the terminals sending detection positioning signals (SRS POS) correspond to different sub-resource pools. The sub-resource pools are orthogonal in time / frequency / code domain resources, such as time domain resource set / resource orthogonal, frequency domain BWP or comb orthogonal, code domain CS orthogonal, etc.

[0205] The third method is that when LMF pre-configures the resources used by each terminal corresponding to different cell groups to send the detection positioning signal (SRS POS), when dividing the cell groups, it ensures that the isolation of different cell groups in geographical space is greater than or equal to the threshold to avoid resource interference through spatial isolation coordination.

[0206] By adopting the technical solution of the embodiment of the present invention, the LMF entity can configure the resources used by each terminal corresponding to each target cell to send the detection and positioning signal to be orthogonal for each target cell in the same cell group, and send the corresponding configuration information to each terminal; it can also configure the resources used by each terminal in different target cells corresponding to different cell groups to send the detection and positioning signal to be orthogonal, and send the corresponding configuration information to each terminal. In this way, it can ensure that the resources used by multiple terminals to send the measurement results of the detection and positioning signals do not conflict, thereby ensuring that the LMF entity can achieve accurate positioning of the terminal.

[0207] In order to implement the resource configuration method of the embodiment of the present invention, the embodiment of the present invention also provides a resource configuration device.
