technical field

The present application belongs to the technical field of communication, and in particular relates to a method for configuring an uplink positioning reference signal (SRS), a terminal and a network side device.

Background technique

A positioning method based on an uplink reference signal is introduced in related technologies, specifically: Position Sounding Reference Signal (Pos SRS) configuration is requested by the Location Management Function (LMF) and finally determined by the serving base station , and then forwarded to the terminal through the LMF. During the positioning process, the LMF requests the relevant base stations (that is, the serving base station and the neighboring base stations) to measure the Pos SRS, and after receiving the measurement results of the relevant base stations, determines the positioning result of the terminal through calculation.

However, each terminal has its own Pos SRS configuration. If the terminal is handed over or resumed to a new cell during the mobile process, the target base station corresponding to the new cell may change the configuration of the original serving base station due to resource configuration conflicts. The Pos SRS configuration is released, causing the relevant base stations to be unable to receive Pos SRS after that, so that the Pos SRS measurement results cannot be obtained. At this time, the relevant base station will feed back the measurement failure to the LMF, and the LMF can request Pos SRS configuration again. During the positioning process, if the terminal moves in a large range, it will cause frequent reconfiguration of the Pos SRS configuration, resulting in a long positioning delay.

Fig. 1 shows a block diagram of a wireless communication system to which the embodiment of the present application is applicable. The wireless communication system includes a terminal 11 and a network side device 12 .

As shown in Figure 2, in related technologies, the uplink positioning process of UE mainly includes the following steps:

Step 1, LMF obtains sending and receiving point (TRP) information;

Step 2, the LMF obtains the UE positioning capability;

Step 3. The LMF sends a New Radio (NR) Positioning Protocol A (NR Positioning Protocol A, NRPPa) message: POSITIONING INFORMATION REQUEST to the serving base station to request the Pos SRS configuration information of the target UE;

Step 4, the serving base station determines the Pos SRS configuration and sends the Pos SRS configuration to the target UE;

Step 5. The serving base station sends the Pos SRS configuration to the LMF through the NRPPa message: POSITIONING INFORMATION RESPONSE;

Step 6. For semi-persistent or aperiodic Pos SRS, the LMF will request the serving base station to activate the Pos SRS configuration through the NRPPa message: Positioning Activation Request, such as through the media access control unit (Medium Access Control-Control element, MAC CE) or downlink control information (Downlink Control Information, DCI) activates the Pos SRS configuration, and after activation, the serving base station feeds back the NRPPa message: NRPPa Positioning Activation Response (NRPPa Positioning Activation Response) to confirm the Pos SRS configuration activated;

Step 7. The LMF sends the Pos SRS configuration to the relevant base station through the NRPPa message: MEASUREMENT REQUEST, and requests the relevant base station to perform SRS measurement based on the SRS configuration;

Step 8, the relevant base station performs SRS measurement based on the configuration;

Step 9, the relevant base station feeds back the SRS measurement result through the NRPPa message: Measurement Response (Measurement Response);

Step 10, LMF sends NRPPa message: POSITIONING DEACTIVATION command to the serving cell to deactivate or release Pos SRS configuration.

In the uplink positioning process as shown in Figure 2, if the relevant base station cannot obtain the SRS measurement result, then feed back the NRPPa message to the LMF: measurement failure indication (MEASUREMENT FAILURE INDICATION), the measurement failure indication can indicate that the requested item is temporarily unavailable (Requested Item Temporarily not Available), specifically, the measurement failure indication is sent by the NG-RAN node to indicate that the previously requested measurement can no longer be reported. For example: the measurement fault indication can be in the form of information (Information Element, IE) structure as shown in Table 1 below:

Table 1

At this point, the LMF can request the serving base station to reconfigure the SRS based on receiving the measurement failure indication, and the base station can send a POSITIONING INFORMATION UPDATE message to the LMF to send a Pos SRS configuration update. Specifically, if the Pos SRS configuration ( configuration) information is included in this message, which the LMF shall regard as the UE's latest Pos SRS configuration. Among them, the NRPPa Transaction ID information in the measurement fault indication is used to associate with the same positioning process. Specifically, the above positioning information update message is sent by the NG-RAN node to the LMF to indicate that the Pos SRS configuration has changed. For example, the positioning information update message may have the information structure shown in Table 2 below:

Table 2

It can be seen from the above that since the Pos SRS configuration in the related art is specific to the target UE (UE-specific), if a handover or Resume to a new serving cell occurs during UE movement, the target base station (the base station corresponding to the new serving cell) may Due to resource configuration conflicts, the positioning (Pos) SRS configured by the original serving base station is released, so that the relevant base station cannot obtain the Pos SRS measurement result after that. At this time, the relevant base station will feedback that the SRS measurement fails, and the LMF can re-request Pos SRS configuration to the target base station according to the SRS measurement failure. In this way, for a target UE that requires periodic or frequent positioning, if the UE moves within a relatively large range, frequent Pos SRS reconfiguration will result, increasing the positioning delay.

However, in this embodiment of the present application, at least one uplink positioning SRS (for example: Pos SRS) is pre-configured for the terminal, so that even if the serving cell or the resident cell changes during the moving process of the terminal, the terminal, serving The interaction between the cell/resident cell and the LMF can also select a valid one for the terminal from at least one uplink positioning SRS pre-configuration as the uplink positioning SRS configuration, so as to ensure the mobility of the terminal uplink positioning, reduce the reconfiguration of the SRS, and further Reduce positioning delay.

It should be noted that the above-mentioned uplink positioning SRS can also be called: uplink positioning sounding reference signal or simply called uplink positioning reference signal, or can also be called uplink Pos SRS. For the convenience of description, in the following embodiments of the present application It is collectively referred to as the uplink positioning SRS.

The following describes in detail the uplink positioning SRS configuration method, uplink positioning SRS configuration device, network side equipment, terminal and readable storage medium provided by the embodiments of the present application through some embodiments and application scenarios with reference to the accompanying drawings.

Please refer to FIG. 3, the execution body of the first SRS configuration method for uplink positioning provided by the embodiment of the present application may be the first network side device. As shown in FIG. 3, the first SRS configuration method for uplink positioning may include the following steps:

Step 301, the first network-side device obtains at least one uplink positioning SRS pre-configuration of the terminal from at least one second network-side device.

Optionally, the first network side device includes at least one of the following: location management function LMF network element, enhanced serving mobile location center (evolved Serving Mobile Location Center, eSMLC) and secure user plane location (Secure User Plane Location , SUPL) Platform (SUPL Location Platform, SLP);

The second network side device includes at least one of a TRP and a base station.

In a specific implementation, the above-mentioned first network-side device may be an LMF, and the above-mentioned second network-side device may include a network-side device corresponding to a serving cell and/or a neighboring cell of the terminal.

The differences between the above SRS pre-configuration for uplink positioning and the SRS configuration for uplink positioning in the related art include:

1) A terminal can be configured with one or more uplink positioning SRS pre-configurations, while a terminal in the related art can only be configured with one uplink positioning SRS configuration;

2) In the embodiment of this application, after the uplink positioning SRS pre-configuration is configured to the terminal, if the serving cell or the camping cell of the terminal changes, the uplink positioning SRS pre-configuration outside the effective area will not be deleted, while the related technology Among them, after the terminal configures the uplink positioning SRS configuration, the terminal immediately executes the uplink positioning SRS configuration, and when the serving cell or the cell of the terminal changes, the current uplink positioning may be released due to resource conflicts and other factors. positioning SRS configuration, and in the case that the LMF fails to receive the SRS measurement sent by the positioning-related base station, it requests the changed serving cell for the uplink positioning SRS configuration again.

Step 302. The first network side device generates an uplink positioning SRS preconfiguration set for the terminal, wherein the uplink positioning SRS preconfiguration set includes the at least one uplink positioning SRS preconfiguration.

In implementation, after the first network-side device generates the uplink positioning SRS pre-configuration set of the terminal, the uplink positioning SRS pre-configuration set may be sent to the corresponding terminal and the second network-side device related to the terminal positioning (the serving cell and neighboring cells of the terminal), so that the terminal transmits positioning SRS signals according to at least part of the uplink positioning SRS pre-configuration in the uplink positioning SRS pre-configuration set, and the serving cell and neighboring cells perform corresponding SRS Measurement.

Optionally, each uplink positioning SRS pre-configuration in the uplink positioning SRS pre-configuration set includes at least one of the following:

A first uplink positioning SRS configuration identifier, wherein the first uplink positioning SRS configuration identifier is used to distinguish each uplink positioning SRS pre-configuration in the terminal;

Types of uplink positioning SRS configurations, where the types of uplink positioning SRS configurations include uplink positioning SRS configurations and uplink positioning SRS pre-configurations;

An operation identifier for uplink positioning SRS pre-configuration;

Valid time of uplink positioning SRS pre-configuration;

The first information field is used to bear the uplink positioning SRS pre-configuration associated with the first uplink positioning SRS configuration identifier;

The second information field is used to bear the valid area of the uplink positioning SRS pre-configuration associated with the first uplink positioning SRS configuration identifier.

Option 1: The above-mentioned first uplink positioning SRS configuration identifier can be in one-to-one correspondence with the uplink positioning SRS preconfiguration set in the uplink positioning SRS preconfiguration set, so that the terminal can distinguish the uplink positioning SRS according to the first uplink positioning SRS configuration identifier Each uplink positioning SRS in the pre-configuration set is pre-configured, for example: the first uplink positioning SRS configuration identifier can be LMF SRS config (configuration) identifier (Identifer, ID)+radio access network (Radio Access Network, RAN) SRS config In this way, the terminal can distinguish different uplink positioning SRS pre-configurations according to the LMF SRS config ID, and can distinguish different uplink positioning SRS pre-configurations configured by the second network side device according to the RAN SRS config ID.

Option 2: Since the uplink positioning SRS pre-configuration set may include legacy (legacy) SRS configuration or SRS pre-configuration, the SRS configuration in the uplink positioning SRS pre-configuration set can be distinguished through the type of the above-mentioned uplink positioning SRS configuration is legacy configuration Still pre-configured. For example, the configuration type of the uplink positioning SRS may be a pre-configuration (pre-configuration) indicator, and if the pre-configuration is true (true), it means that the corresponding uplink positioning SRS pre-configuration type is pre-configuration.

Option 3: During implementation, the first network side device can also perform operations on the uplink positioning SRS pre-configuration in the uplink positioning SRS pre-configuration set, for example: adding, deleting, modifying pre-configuration, etc., by providing the uplink positioning SRS The uplink positioning SRS pre-configuration in the pre-configuration set adds a corresponding operation identifier, which can implement the corresponding operation on the uplink positioning SRS pre-configuration in the uplink positioning SRS pre-configuration set.

Option 4: In implementation, each uplink positioning SRS pre-configuration has its own valid time. After the terminal receives the pre-configured uplink positioning SRS, the configuration is valid within the valid time of the uplink positioning SRS pre-configuration. The configuration becomes invalid after its effective time.

Optionally, the terminal does not release the uplink positioning SRS pre-configuration before, but after the valid time of the uplink positioning SRS pre-configuration, the terminal may release the uplink positioning SRS pre-configuration.

In implementation, before the effective time of a certain uplink positioning SRS pre-configuration, if the terminal is located outside the valid area of the uplink positioning SRS pre-configuration, the terminal will not release the uplink positioning SRS pre-configuration. During the moving process, if the terminal moves within the effective area of the uplink positioning SRS pre-configuration, the uplink positioning SRS pre-configuration may be performed.

In this embodiment, after the uplink positioning SRS pre-configuration becomes invalid, the terminal can release the invalid uplink positioning SRS pre-configuration in time to reduce the energy consumption of the terminal.

Option 5: Uplink positioning SRS pre-configuration associated with the first uplink positioning SRS configuration identifier, which means that the uplink positioning SRS pre-configuration is associated with the corresponding first uplink positioning SRS configuration identifier, so that through the interaction of the first uplink positioning SRS configuration identifier, Then the corresponding uplink positioning SRS pre-configuration can be determined.

Option 6: The pre-configured effective area of the uplink positioning SRS is associated with the corresponding first uplink positioning SRS configuration identifier. During implementation, the terminal can judge the uplink positioning SRS according to whether it is located in the specific uplink positioning SRS pre-configured effective area Whether the pre-configuration is valid for the terminal, that is, the configuration is valid when the terminal moves into the valid area, and invalid when the terminal moves outside the valid area.

In this way, when it is determined that the uplink positioning SRS pre-configuration is valid, the first uplink positioning SRS configuration identifier corresponding to the uplink positioning SRS pre-configuration may be reported to the LMF and the current serving cell, so that the LMF and the current serving cell Informing the positioning-related base station to perform corresponding SRS measurement according to the uplink positioning SRS pre-configuration corresponding to the first uplink positioning SRS configuration identifier.

Optionally, the second information field includes at least one of the following:

A list of cell identifiers, wherein the cell is a serving cell or a cell where the terminal resides;

Preset effective area;

Preset SRS measurement change threshold.

Wherein, the cell identifier may be a cell ID such as a physical cell identification code (Physical Cell Identification, PCI) or a cell global identifier (Cell Global Identifier, CGI).

In addition, the aforementioned preset effective area can be understood as a certain area delineated by a curve, or an area within a certain range from a certain route.

The above preset SRS measurement change threshold can be expressed as, if the change of the preset SRS measurement value is less than or equal to the preset SRS measurement change threshold, it means that the corresponding area is an effective area, if the preset SRS measurement value is greater than the preset SRS If the measurement variation threshold indicates that the corresponding area is an invalid area, for example, if the variation of the Reference Signal Received Power (RSRP) of the SSB does not exceed a certain threshold, then the corresponding terminal can determine the pre-configured measurement interval configuration valid, otherwise invalid.

As an optional implementation manner, the first network-side device acquires at least one uplink positioning SRS pre-configuration of the terminal from at least one second network-side device, including:

The first network-side device sends an uplink positioning SRS pre-configuration request for the terminal to at least one second network-side device;

The first network side device receives at least one uplink positioning SRS preconfiguration response from the at least one second network side device, wherein each of the uplink positioning SRS preconfiguration responses carries at least one uplink positioning SRS preconfiguration.

In a specific implementation, the above-mentioned uplink positioning SRS pre-configuration request may be a request message specially used to request uplink positioning SRS pre-configuration, or the uplink positioning SRS configuration request in related technologies may be multiplexed, and the uplink positioning SRS configuration request The preconfiguration indication information is carried to notify the second network side device to feed back the uplink positioning SRS preconfiguration configured for the terminal to the first network side device.

For example: the LMF can request uplink positioning SRS pre-configuration from the serving cell and neighboring cells of the terminal, and the request can be carried in the Requested SRS configuration message, so that the serving cell and neighboring cells can base the requested uplink positioning SRS The configuration message determines the uplink positioning SRS pre-configuration, the serving cell sends the determined legacy (legacy) uplink positioning SRS configuration to the terminal through a radio resource control (Radio Resource Control, RRC) message, and the uplink positioning SRS configuration (including legacy configuration and pre-configuration) to the LMF, and the neighboring cell only sends the uplink positioning SRS pre-configuration to the LMF. In this way, the LMF can organize all the received uplink positioning SRS configurations (including legacy configurations and pre-configurations), so as to generate an uplink positioning SRS pre-configuration set for the terminal.

In an implementation, the uplink positioning SRS pre-configuration set may include the terminal's current uplink positioning SRS configuration (legacy configuration) and uplink positioning SRS pre-configuration, and when the serving cell of the terminal changes or the effective uplink positioning SRS configuration In the case of a change, the terminal will not delete the uplink positioning SRS configuration. At this time, the uplink positioning SRS configuration is equivalent to an uplink positioning SRS pre-configuration of the terminal. For the convenience of description, the uplink positioning SRS The uplink positioning SRS configurations in the pre-configuration set are collectively referred to as uplink positioning SRS pre-configurations.

Optionally, the uplink positioning SRS preconfiguration request includes at least one of the following:

The type of the requested uplink positioning SRS configuration, where the type of the uplink positioning SRS configuration includes uplink positioning SRS configuration and uplink positioning SRS pre-configuration;

The requested uplink positioning SRS time domain resource, for example: period length, period transmission times, etc.;

The requested uplink positioning SRS frequency domain resource, for example: frequency domain bandwidth;

The requested uplink positioning SRS spatial correlation, for example: the spatial correlation with the synchronization signal block (Synchronization Signal and PBCH block, SSB).

Option 1: The capability information of the terminal may be bandwidth supported by the terminal, carrier aggregation (Carrier Aggregation, CA) combination, etc., which are used for the second network side device to configure available SRS resources for the terminal.

Option 2: The above-mentioned second uplink positioning SRS configuration identifier may be an LMF SRS config ID, and the LMF SRS config ID can distinguish the SRS configurations requested by the first network side device from different second network side devices respectively.

Optionally, the uplink positioning SRS preconfiguration response includes at least one of the following:

A third uplink positioning SRS configuration identifier, where the third uplink positioning SRS configuration identifier is used to distinguish respective uplink positioning SRS pre-configurations in each second network side device;

Valid time of uplink positioning SRS pre-configuration;

The third information field is used for the uplink positioning SRS pre-configuration associated with the third uplink positioning SRS configuration identifier;

The fourth information field is used for the valid area of the associated uplink positioning SRS pre-configuration identified by the third uplink positioning SRS configuration.

In implementation, in view of the fact that a second network side device may configure multiple uplink positioning SRS pre-configurations for the same terminal, the above-mentioned third uplink positioning SRS configuration identifier may be LMF SRS config ID+RAN SRS config ID, wherein the same second network The uplink positioning SRS pre-configuration configured by the side device has its own RAN SRS config ID. In this way, through the combination of the LMF SRS config ID and the RAN SRS config ID, the first network side device and the terminal can distinguish each uplink positioning SRS pre-configuration.

In addition, the specific meaning and function of the above-mentioned uplink positioning SRS configuration type, valid time, third information field and fourth information field are the same as the type and valid time of each uplink positioning SRS preconfiguration set in the uplink positioning SRS preconfiguration set , the first information domain, and the second information domain are the same respectively, and will not be repeated here.

In this embodiment, the existing Requested SRS configuration message can be reused to request the uplink positioning SRS pre-configuration, thus avoiding the waste of resources caused by separately sending the requesting uplink positioning SRS pre-configuration message.
