Detailed Description

Before the technical solution of the embodiment of the present invention is introduced, a description is given of a related art.

In the related art, NR R16 supports acquisition of positioning information of a terminal through transmission and reception of a reference signal. For example, an Arrival Time Difference (OTDOA) positioning technique is that a terminal receives downlink reference signals transmitted by a plurality of base stations, and calculates Arrival Time differences of the reference signals of different base stations to obtain location information of the terminal; the Uplink Time Difference of Arrival (UTDOA) positioning technique is a technique in which a plurality of base stations receive Uplink reference signals transmitted by a terminal, and the Time Difference between the Uplink reference signals arriving at different base stations is used to calculate the position information of the terminal. An uplink Sounding Reference Signal (SRS) in R16 may be used for air interface positioning of a User Equipment (UE).

Fig. 1 is a schematic flow chart of implementing configuration of a sounding positioning signal by a base station in the related art, as shown in fig. 1, including:

step 0: and the LMF entity requests and acquires the TRP information.

Step 1: the LMF entity requests UE capabilities (by LPP).

Step 2-4: the LMF entity requests SRS configuration of the UE from the serving gNB; after determining the configuration, the gNB sends the configuration to the UE and reports the configuration to the LMF entity;

here, the LMF entity may carry recommended configuration information when requesting SRS configuration of the UE, as shown in fig. 2. The gNB refers to the recommended configuration sent by the LMF entity, and determines the final SRS configuration of the UE according to the actual scheduling condition; and the gNB sends the SRS configuration to the UE and reports the SRS configuration to the LMF entity.

And 5: the LMF entity sends a request to activate/deactivate the SRS configuration of the UE; activating/deactivating SRS configuration of the UE by the gNB by using the MAC-CE;

and 6-8: the LMF entity initiates a measurement request; the gNB/TRP carries out UL SRS measurement and reports the measurement result to the LMF entity;

here, when initiating the measurement request, the LMF entity sends SRS configuration related information of the complete UE to the gNB/TRP to be measured, as shown in fig. 3.

Here, the selected gNB/TRP to measure is measured and the measurement result is reported. Here, the measurement results reported to the LMF entity by the gNB/TRP are shown in fig. 4.

In summary, in the related art, each base station may refer to the recommended configuration of the LMF entity to configure, by the UE, resources used for sending SRS Pos for positioning, and report the configuration condition to the LMF entity. When the positioning measurement request is triggered (step 6 in fig. 1), the neighbor nbs/TRPs to be measured receives the measurement result of the SRS PoS sent by the terminal according to the SRS PoS configuration information, and reports the measurement result to the LMF entity. Because there is no coordination mechanism between the LMF entity and the base station, it is difficult to avoid that resource configurations used by different terminals to report SRS PoS do not conflict, thereby affecting the positioning accuracy. For example, it is assumed that a resource configuration used by a certain UE in a serving cell a (serving cell a) to send an SRS pos is the SRS pos a, and a resource configuration used by an SRS pos sent by a neighboring UE to the serving cell a is also the SRS pos a, and it can be seen that the resource configurations used by the UE in the cell and the SRS pos sent by the neighboring UE to the serving cell a are in conflict. For another example, a resource used by the cell a (cell a) to transmit the SRS pos for the UE _ a of the cell is configured as the SRS pos a, a resource used by the cell B (cell B) to transmit the SRS pos for the UE _ B of the cell is configured as the SRS pos B, both the cells are close to (forward) one neighboring cell, that is, the cell c (cell c), and the SRS pos a and the SRS pos B use the same time-frequency code resource, so that the SRS pos a and the SRS pos B interfere with each other.

Based on this, in the embodiments of the present invention, the resources used by the terminals corresponding to each target cell to send the sounding positioning signal are configured to be orthogonal; the target cell is a cell for receiving the detection positioning signal; and determining the configuration information of the detection positioning signals respectively corresponding to the terminals.

The present invention will be described in further detail with reference to the accompanying drawings and examples.

An embodiment of the present invention provides a resource allocation method, which is applied to an LMF entity, and as shown in fig. 5, the method includes:

step 501: configuring the resources used by each terminal corresponding to each target cell for sending the detection positioning signals to be orthogonal; the target cell is a cell for receiving the detection positioning signal;

step 502: and determining the configuration information of the detection positioning signals respectively corresponding to the terminals.

Here, in step 501, the LMF entity may have a coordination function, that is, the LMF entity may configure resources used by terminals corresponding to each target cell to send probe positioning signals. In practical application, the LMF entity may configure a plurality of cells in the jurisdiction area as at least one cell group, and configure the resources used by the plurality of terminals of each target cell in the same cell group to send sounding positioning signals to be orthogonal, and/or configure the resources used by the terminals of different target cells corresponding to different cell groups to send sounding positioning signals to be orthogonal, so that the problem that the LMF entity cannot accurately position due to resource collision used by the plurality of terminals to send sounding positioning signals in the related art can be avoided. The sounding positioning signal may refer to a sounding reference signal for positioning.

Here, in step 502, the LMF entity may further configure configuration information of the sounding positioning signal for a plurality of terminals of each target cell, and send the configuration information to the served terminal through the base station located in the serving cell, and the terminal completes measurement of the sounding positioning signal, report of the measurement result, and the like according to the received configuration information.

It should be noted that, in the embodiment of the present invention, the LMF entity may configure, as orthogonal, resources used by terminals corresponding to each target cell in the same cell group to send sounding positioning signals, or configure, as orthogonal, resources used by terminals corresponding to different target cells in different cell groups to send sounding positioning signals.

The following describes in detail how the LMF entity configures the resource used by each terminal corresponding to each target cell in the same cell group to send the sounding positioning signal to be orthogonal.

In actual application, before configuring the resources used by each terminal corresponding to each target cell in the same cell group to send sounding and positioning signals to be orthogonal, the LMF entity may divide a plurality of cells in the jurisdiction into at least one cell group, where each cell group may include at least one target cell.

Based on this, in an embodiment, the configuring, to be orthogonal, resources used by terminals corresponding to each target cell to transmit sounding positioning signals includes:

For example, as shown in table 1, the LMF entity may divide the cells 1, 2, 3, and 4 in the jurisdiction into a cell group, and divide the target cell into the cell 1, 2, 3, and 4; or, dividing the cells 3 in the jurisdiction range into a cell group, and dividing the target cell into the cells 3; or, the cells 4 and 5 in the jurisdiction range are divided into a cell group, and the target cell is divided into the cells 4 and 5; or, dividing the cells 6, 7 and 8 in the jurisdiction range into a cell group; the target cell is divided into a cell 6, a cell 7 and a cell 8.

Cell group numbering	Target cell comprised by a group of cells
		Cell group1	Cell 1, cell 2, cell 3, cell 4
Cell group2	Cell 3
		Cell group3	Cell 4, cell 5
Cell group 4	Cell 6, cell 7, cell 8

Here, if the LMF entity divides at least two cells administered into at least one cell group, resources used by terminals corresponding to each target cell in the same cell group to send sounding positioning signals may be configured to be orthogonal.

In practical application, the resource used by the terminal for sending the detection positioning signal can be a time domain resource, a frequency domain resource and the like, so that when the resource used by the terminal for sending the detection positioning signal to the target cell is the time domain resource, the orthogonality of the time domain resource can be realized in a time division multiplexing mode; when the resource used by the terminal for sending the detection positioning signal to the target cell is a frequency domain resource, the frequency domain resource can be orthogonal in a frequency division multiplexing mode; when the resource used by the terminal for sending the detection positioning signal to the target cell is a code domain resource, the orthogonality of the frequency domain resource can be realized through a code division multiplexing mode.

For the terminal UE42 of the target cell 2 serving as the neighboring cell of the serving cell, the LMF entity configures the resources used by the terminal UE42 of the target cell serving as the neighboring cell of the serving cell to send the sounding positioning signal to be orthogonal, where the sounding positioning signal sent by the UE42 to the gNB2 may be represented by UE42- > gNB2, and after determining the configuration information of the corresponding sounding positioning signal, the configuration information of the sounding positioning signal may be sent to the terminal UE42 through the target cell 4 of the serving terminal UE42, as shown in table 7.

TABLE 7

In practical application, after configuring the resources used by each terminal corresponding to each target cell to send the sounding positioning signal to be orthogonal, the LMF entity may also configure the configuration information of the corresponding sounding positioning signal for each terminal.

Based on this, in an embodiment, the configuration information of the sounding positioning signal includes:

resource configuration information;

path loss reference information;

spatial correlation information;

the resource configuration information is used for representing the resource orthogonality used by each terminal corresponding to each target cell for sending the detection positioning signal; the path loss reference signal is used for calculating the uplink transmission power of each terminal which is served by each target cell and used for transmitting the detection positioning signal; the spatial correlation information is used to determine uplink transmission beams used by terminals served by each target cell to transmit sounding positioning signals.

Here, the configuration information of the sounding positioning signal includes, but is not limited to: path loss reference information (pathloss reference) and spatial correlation information (spatial correlation info) for a serving cell (serving cell) and a neighboring cell (neighbor cells) of the terminal, and the like.

In an example, as shown in fig. 7, a process that an LMF entity configures resources used by terminals corresponding to each target cell in the same cell group to send sounding positioning signals to be orthogonal is described, where the process includes:

step 701: and the LMF entity configures the resources used for sending the uplink detection positioning signals to each terminal of each target cell in the same cell group to be orthogonal.

Specifically, the process of integrally configuring, by an LMF entity, resources used by each terminal of each target cell in the same cell group to transmit an uplink sounding positioning signal (SRS pos) includes:

step 1: the LMF entity requests and acquires information of all TRPs or gNBs and capability information of the UE in the same cell group.

Here, the LMF entity may request and acquire information of all TRPs or gnbs and capability information of the UE in the same cell group based on the LPP protocol.

Step 2: and the LMF entity integrally configures resources used by each terminal of each target cell in the same cell group for sending uplink sounding positioning signals (SRS pos) to be orthogonal in a time/frequency/code resource domain.

The uplink sounding positioning signal (UL SRS pos) associated with the target cell (target cell) may be sent by the UE using the target cell as a serving cell, or sent by the UE using the target cell as a neighbor cell of the neighbor cell.

Here, the time domain resource orthogonality may mean that the resource orthogonality is achieved through SRS resource set and SRS resource equal time division multiplexing; frequency domain resource orthogonality may refer to resource orthogonality achieved using different active BWPs, or frequency domain comb (comb) equal frequency division multiplexing; code domain resource orthogonality may refer to achieving resource orthogonality using different cyclic shifts (cyclic shifts).

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

And step 3: and the LMF determines the configuration information of the sounding positioning signals of the UE corresponding to each target cell in the same group by combining the configuration principle of the sounding positioning signals (SRS Pos).

Here, the configuration information includes: the path reference and the Spatial reference info of the serving cell associated with the terminal, and the path reference and the Spatial reference info of the neighbor cell associated with the terminal, etc.

Step 702: and the LMF entity performs resource configuration based on the service cells in the same cell group.

Specifically, after the LMF entity integrally configures resources used by each terminal of each target cell in the same cell group to transmit the uplink sounding positioning signal, SRS pos resources of one or more UEs served by the same serving cell are configured and recommended to the serving cell, and the serving cell schedules the SRS pos resources to the served one or more UEs.

Here, the LMF entity configures the resources used by the terminals corresponding to each target cell in the same cell group to send the sounding and positioning signals to be orthogonal, and has the following advantages:

(1) the LMF entity has a coordination function, namely, the LMF entity can configure a plurality of cells of the jurisdiction range into at least one group, and each group comprises at least one target cell; and the resources used by the multiple terminals of each target cell in the same cell group for sending the sounding positioning signals can be configured to be orthogonal so as to avoid resource interference, thus the problem that an LMF entity cannot be accurately positioned due to resource conflict caused by the multiple terminals for sending the sounding positioning signals in the related technology can be avoided.

(2) A method for configuring resources used for transmitting sounding positioning signals for a plurality of terminals of each target cell in the same cell group is provided.

(3) For an R17 indoor factory scenario, considering that the number of gnbs/TRPs in a typical factory is limited, the LMF may configure orthogonal resource configurations used by UEs under each gNB/TRP in the factory area to transmit sounding positioning signals (SRS pos).

(4) The resources used by the terminals for sending the sounding positioning signals aiming at different target cells in the same cell group do not need to be configured to be orthogonal, and the utilization rate of the resources needed by sending the sounding positioning signals can be improved.

The following is a detailed description of how the LMF entity configures the resource used by each terminal corresponding to different cell groups to send sounding positioning signals to be orthogonal.

In practical application, in order to avoid the problem that the LMF entity cannot be accurately positioned due to resource collision used by multiple terminals to send sounding positioning signals in the related art, for each target cell of different cell groups, the resources used by the target cell to send sounding positioning signals as each terminal of the serving cell and/or as each terminal of the neighboring cell of the serving cell may be configured to be orthogonal.

Based on this, in an embodiment, the method further comprises:

and configuring the resources used by the terminals respectively corresponding to different cell groups for sending the sounding positioning signals to be orthogonal.

In practical application, the orthogonality of the resources used by the terminals corresponding to different cell groups for sending the sounding positioning signals can be realized by means that different beam resources, different sub-resource pools and spatial isolation meet a threshold.

Based on this, in an embodiment, the configuring, to be orthogonal, resources used by terminals corresponding to different cell groups to transmit sounding positioning signals includes one of:

configuring different space domain resources to realize orthogonality through resources used by each terminal respectively corresponding to different cell groups to send detection positioning signals, wherein the space domain resources comprise: a beam resource;

For example, fig. 8 is a schematic diagram of a plurality of Cell groups, and as shown in fig. 8, the plurality of Cell groups are represented by a Cell Group 1(Cell Group1), a Cell Group 2(Cell Group2), and a Cell Group 3(Cell Group3), and an LMF entity configures resources used by terminals corresponding to different Cell groups to send sounding positioning signals (SRS POS) into an orthogonal process, which is specifically as follows:

in the first mode, resources used by terminals corresponding to different cell groups to transmit sounding reference signals (SRS POS) may be configured as different beam resources to avoid interference through spatial beam coordination, where the beam resources may be narrow beams.

In the second mode, the LMF pre-configures each terminal corresponding to different cell groups to send sounding positioning signals (SRS POS) corresponding to different sub-resource pools (sub-resource pools), where the sub-resource pools are orthogonal in time/frequency/code domain resources, such as time domain resource set/resource orthogonality, frequency domain BWP or comb orthogonality, code domain CS orthogonality, and the like.

In a third mode, when the LMF pre-configures resources used by each terminal corresponding to different cell groups for sending sounding positioning signals (SRS POS), and when the cell groups are divided, the isolation degree of the different cell groups in the geographic space is ensured to be larger than or equal to a threshold value so as to avoid resource interference through space isolation degree coordination.

By adopting the technical scheme of the embodiment of the invention, the LMF entity can configure the resource used by each terminal corresponding to each target cell for sending the detection positioning signal to be orthogonal aiming at each target cell in the same cell group and send the corresponding configuration information to each terminal; and the resource configuration used for sending the detection positioning signal by aiming at each terminal of different target cells corresponding to different cell groups can be orthogonal, and the corresponding configuration information is sent to each terminal, so that the resources used for sending the measurement result of the detection positioning signal by a plurality of terminals can be ensured not to conflict, and the LMF entity can be ensured to realize accurate positioning of the terminal.
