Description

Uplink positioning reference signal SRS configuration method, terminal and network side equipment

Technical Field

The application belongs to the technical field of communication, and particularly relates to an uplink positioning reference signal (SRS) configuration method, a terminal and network side equipment.

Background

A positioning method based on an uplink reference signal is introduced in the related art, and specifically comprises the following steps: the Location Sounding Reference Signal (Pos SRS) configuration is initiated by a Location Management Function (LMF) to be finally determined by the serving base station, and then forwarded to the terminal through the LMF. In the positioning process, the LMF requests the relevant base stations (i.e., the serving base station and the neighboring base stations) to measure the Pos SRS, and determines the positioning result of the terminal through calculation after receiving the measurement result of the relevant base stations.

However, each terminal has its own Pos SRS configuration, and if the terminal is handed over or recovered (Resume) to a new cell during a moving process, a target base station corresponding to the new cell may release the Pos SRS configuration configured by an original serving base station due to resource configuration conflict, so that a related base station cannot receive the Pos SRS after that, and thus cannot obtain a Pos SRS measurement result. At this time, the relevant base station fails to feed back the measurement to the LMF, and the LMF may re-request the Pos SRS configuration. In the positioning process, if the mobile range of the terminal is large, frequent reconfiguration of Pos SRS configuration is caused, so that the positioning delay is long.

The terms "system" and "network" in the embodiments of the present application are often used interchangeably, and the described techniques can be used for both the above-mentioned systems and radio technologies, as well as for other systems and radio technologies. The following description describes a New Radio (NR) system for purposes of example, and NR terminology is used in much of the description below, but the techniques may also be applied to applications other than NR systems applications, such as 6th generation,6g communication systems.

Fig. 1 shows a block diagram of a wireless communication system to which embodiments of the present application are applicable. The wireless communication system includes a terminal 11 and a network-side device 12. Wherein, the terminal 11 may be a Mobile phone, a Tablet Personal Computer (Tablet Personal Computer), a Laptop Computer (Laptop Computer) or a terminal-side Device called as a notebook Computer, a Personal Digital Assistant (PDA), a palm Computer, a netbook, an ultra-Mobile Personal Computer (ultra-Mobile Personal Computer, UMPC), a Mobile Internet Device (Mobile Internet Device, MID), an augmented reality (augmented reality, AR)/Virtual Reality (VR) Device, a robot, a Wearable Device (Wearable Device), a vehicle-mounted Device (VUE), a pedestrian terminal (PUE), a smart home (a Device with wireless communication function, such as a refrigerator, a television, a washing machine, or furniture), and the like, and the terminal includes: smart watch, smart bracelet, smart earphone, smart glasses, smart jewelry (smart bracelet, smart ring, smart necklace, smart anklet, etc.), smart wristband, smart garment, game console, etc. It should be noted that the embodiment of the present application does not limit the specific type of the terminal 11. The network-side device 12 may be a Base Station or a core network, wherein the Base Station may be referred to as a node B, an evolved node B, an access Point, a Base Transceiver Station (BTS), a radio Base Station, a radio Transceiver, a Basic Service Set (BSS), an Extended Service Set (ESS), a node B, an evolved node B (eNB), a home node B, a WLAN access Point, a WiFi node, a Transmit Receive Point (TRP), or some other suitable terminology in the field, as long as the same technical effect is achieved, the Base Station is not limited to a specific technical vocabulary, and it should be noted that in the embodiment of the present application, only the Base Station in the NR system is taken as an example, but the specific type of the Base Station is not limited.

As shown in fig. 2, in the related art, the uplink positioning procedure of the UE mainly includes the following steps:

step 1, LMF acquires the information of a Transmitting and Receiving Point (TRP);

step 2, LMF obtains UE positioning ability;

step 3, the LMF sends a New Radio (NR) positioning protocol A (NRPPa) message: a location INFORMATION REQUEST (position INFORMATION REQUEST) to the serving base station to REQUEST Pos SRS configuration INFORMATION of the target UE;

step 4, the service base station determines Pos SRS configuration and sends the Pos SRS configuration to the target UE;

step 5, the serving base station configures the Pos SRS with NRPPa message: a POSITIONING INFORMATION RESPONSE (POSITIONING INFORMATION RESPONSE) is sent to the LMF;

step 6, for semi-persistent (semi-persistent) or aperiodic (aperiodic) Pos SRS, the LMF will pass NRPPa message: a location Activation Request (location Activation Request) requests the serving base station to activate the Pos SRS configuration, for example, the serving base station activates the Pos SRS configuration through a Medium Access Control-Control element (MAC CE) or Downlink Control Information (DCI), and the activated serving base station feeds back an NRPPa message: positioning an Activation Response (NRPPa Positioning Activation Response) to confirm that the Pos SRS configuration is activated;

step 7, the LMF configures the Pos SRS through NRPPa message: a MEASUREMENT REQUEST (MEASUREMENT REQUEST) is sent to the relevant base station, and the relevant base station is requested to perform SRS MEASUREMENT based on the SRS configuration;

step 8, relevant base stations carry out SRS measurement based on configuration;

and 9, the related base station transmits the NRPPa message: a Measurement Response (Measurement Response) feeds back the SRS Measurement result;

step 10, the LMF sends NRPPa message: a position DEACTIVATION (POSITIONING DEACTIVATION) command is issued to the serving cell to deactivate or release the Pos SRS configuration.

In the uplink positioning process shown in fig. 2, if the relevant base station cannot obtain the SRS measurement result, an NRPPa message is fed back to the LMF: MEASUREMENT FAILURE INDICATION (MEASUREMENT FAILURE INDICATION) which may indicate that the Requested Item is Temporarily unavailable (Requested Item temporal not Available), in particular, 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 may be in the information structure shown in table 1 below:

TABLE 1

/>

At this time, the LMF may request the serving base station to reconfigure the SRS based on receiving the measurement failure indication, and the base station may transmit a location INFORMATION UPDATE (configuration UPDATE) message to the LMF to transmit a Pos SRS configuration UPDATE, specifically, if the Pos SRS configuration (configuration) INFORMATION is included in the message, the LMF should regard it as the latest Pos SRS configuration of the UE. The NRPPa service identification (NRPPa Transaction ID) information in the measurement failure indication is used to associate the same positioning procedure. Specifically, the location information update message is sent by the NG-RAN node to the LMF, and is used to indicate that the Pos SRS configuration has been changed. For example: the location information update message may have an information structure as shown in table 2 below:

TABLE 2

/>

As can be seen from the above, since the Pos SRS configuration in the related art is specific to the target UE (UE-specific), if handover or Resume occurs during the UE moving process to a new serving cell, the target base station (a base station corresponding to the new serving cell) may release the location (Pos) SRS configured by the original serving base station due to resource configuration conflict, so that the related base station cannot obtain the Pos SRS measurement result thereafter. At this time, the relevant base station will feed back SRS measurement failure, and the LMF may request Pos SRS configuration from the target base station again according to the SRS measurement failure. Thus, for a target UE that needs to be periodically or frequently located, if the UE moving range is large, the Pos SRS is frequently reconfigured, and the location delay is increased.

In the embodiment of the application, at least one uplink positioning SRS (for example, pos SRS) is configured for the terminal in advance, so that even if a serving cell or a resident cell is changed in the moving process of the terminal, an effective terminal can be selected from the at least one uplink positioning SRS reconfiguration as the uplink positioning SRS configuration through interaction among the terminal, the serving cell/the resident cell and the LMF, thereby ensuring the mobility of uplink positioning of the terminal, reducing the reconfiguration of the SRS and further shortening the positioning delay.

It should be noted that, the uplink positioning SRS may also be referred to as: for convenience of description, the following embodiments of the present application are collectively referred to as an uplink positioning SRS.

The uplink positioning SRS configuration method, the uplink positioning SRS configuration apparatus, the network side device, the terminal and the readable storage medium provided in the embodiments of the present application are described in detail below with reference to the accompanying drawings and application scenarios thereof.

Referring to fig. 3, an executing entity of a first uplink positioning SRS configuration method provided in the embodiment of the present application may be a first network side device, and as shown in fig. 3, the first uplink positioning SRS configuration method may include the following steps:

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

Optionally, the first network-side device includes at least one of: a Location management function LMF network element, an enhanced Serving Mobile Location Center (eSMLC), and a Secure User Plane Location (SUPL) Platform (SUPL Location Platform, SLP);

the second network side device comprises at least one of a TRP and a base station.

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

The difference between the above uplink positioning SRS pre-configuration and the uplink positioning SRS configuration in the related art includes:

1) One terminal can configure 1 or more uplink positioning SRS preconfigurations, while one terminal in the related art can only configure one uplink positioning SRS configuration;

2) In the embodiment of the present application, after configuring the uplink positioning SRS pre-configuration to the terminal, when the serving cell or the camping cell of the terminal is changed, the uplink positioning SRS pre-configuration outside the effective area is not deleted, but in the related art, after configuring the uplink positioning SRS configuration, the terminal immediately performs the uplink positioning SRS configuration, and when the serving cell or the camping cell of the terminal is changed, the current uplink positioning SRS configuration may be released due to factors such as resource collision, and when the LMF receives an SRS measurement failure sent by the positioning related base station, the LMF re-requests the changed serving cell for the uplink positioning SRS configuration.

Step 302, the first network side device generates an uplink positioning SRS preconfigured set of the terminal, where the uplink positioning SRS preconfigured set includes the at least one uplink positioning SRS preconfigured.

In implementation, after the first network-side device generates the uplink positioning SRS preconfigured set of the terminal, the uplink positioning SRS preconfigured set may be sent to the corresponding terminal and a second network-side device (a serving cell and an adjacent cell of the terminal) related to the terminal positioning, so that the terminal transmits a positioning SRS signal according to at least part of the uplink positioning SRS preconfigured in the uplink positioning SRS preconfigured set, and the serving cell and the adjacent cell perform corresponding SRS measurement.

Optionally, each uplink positioning SRS preconfiguration in the uplink positioning SRS preconfiguration set includes at least one of:

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

the method comprises the following steps of configuring uplink positioning SRS, wherein the type of the uplink positioning SRS configuration comprises the uplink positioning SRS configuration and the uplink positioning SRS pre-configuration;

an operation identifier for uplink positioning SRS pre-configuration;

effective time for uplink positioning SRS pre-configuration;

a first information field, configured to carry uplink positioning SRS pre-configuration associated with the first uplink positioning SRS configuration identifier;

and the second information field is used for bearing an effective area pre-configured by the uplink positioning SRS associated with the first uplink positioning SRS configuration identifier.

Option one: the first uplink positioning SRS configuration identifier may correspond to uplink positioning SRS preconfiguration in an uplink positioning SRS preconfiguration set in a one-to-one manner, so that the terminal may distinguish each uplink positioning SRS preconfiguration in the uplink positioning SRS preconfiguration set according to the first uplink positioning SRS configuration identifier, for example: the first uplink positioning SRS configuration identifier may be an LMF SRS config (configuration) ID + Radio Access Network (RAN) SRS config ID, so that the terminal may distinguish different uplink positioning SRS preconfigurations according to the LMF SRS config ID, and may distinguish different uplink positioning SRS preconfigurations configured by the second Network side device according to the RAN SRS config ID.

And the second option is as follows: in view of whether legacy SRS configuration or SRS pre-configuration may be included in the uplink positioning SRS pre-configuration set, whether SRS configuration in the uplink positioning SRS pre-configuration set is legacy configuration or pre-configuration may be distinguished by the type of the uplink positioning SRS configuration. For example: the type of the uplink positioning SRS configuration may be a pre-configuration (pre-configuration) indicator, and if the pre-configuration is true, it indicates that the type of the uplink positioning SRS pre-configuration is pre-configuration.

And (4) selecting a third option: in implementation, the first network side device may further perform an operation on the uplink positioning SRS preconfiguration in the uplink positioning SRS preconfiguration set, for example: adding, deleting, modifying and the like, and adding corresponding operation identifiers for uplink positioning SRS preconfiguration in the uplink positioning SRS preconfiguration set, so as to realize corresponding operation of the uplink positioning SRS preconfiguration in the uplink positioning SRS preconfiguration set.

And 4, selecting a fourth option: in the implementation, each uplink positioning SRS is preconfigured with respective valid time, and after receiving the preconfigured uplink positioning SRS, the terminal is configured to be valid within the valid time of the uplink positioning SRS, and is configured to be invalid after the valid time.

Optionally, before, the terminal does not release the uplink positioning SRS preconfiguration, and after the effective time of the uplink positioning SRS preconfiguration, the terminal may release the uplink positioning SRS preconfiguration.

In implementation, before an effective time of a certain uplink positioning SRS pre-configuration, if the terminal is located outside an effective area of the uplink positioning SRS pre-configuration, the terminal does not release the uplink positioning SRS pre-configuration, so that in a moving process of the terminal, if the terminal moves to the inside of the effective area of the uplink positioning SRS pre-configuration, the uplink positioning SRS pre-configuration may be performed.

In this embodiment, the terminal may release the failed uplink positioning SRS pre-configuration in time after the uplink positioning SRS pre-configuration fails, so as to reduce energy consumption of the terminal.

And a fifth option: the uplink positioning SRS pre-configuration associated with the first uplink positioning SRS configuration identifier indicates that the uplink positioning SRS pre-configuration is associated with the corresponding first uplink positioning SRS configuration identifier, so that the corresponding uplink positioning SRS pre-configuration can be determined through interaction of the first uplink positioning SRS configuration identifier.

Option six: in implementation, the terminal may determine whether the uplink positioning SRS pre-configuration is valid for the terminal according to whether the terminal is located in the specific uplink positioning SRS pre-configured valid area, that is, when the terminal moves into the valid area, the configuration is valid, and when the terminal moves out of the valid area, the configuration is invalid.

Thus, under the condition that 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 can be reported to the LMF and the current serving cell, so that the LMF and the current serving cell inform 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:

a cell identifier list, wherein the cell is a serving cell or a resident cell of the terminal;

presetting an effective area;

and presetting an SRS measurement change threshold.

The Cell ID may be a Physical Cell Identity (PCI) or a Cell Global Identifier (CGI).

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

The preset SRS measurement change threshold may be represented as that, if a change of the preset SRS measurement value is less than or equal to the preset SRS measurement change threshold, the corresponding area is a valid area, and if the change of the preset SRS measurement value is greater than the preset SRS measurement change threshold, 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, the corresponding terminal may determine that the preconfigured measurement interval configuration is valid, otherwise, it is invalid.

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

a first network side device sends an uplink positioning SRS pre-configuration request to at least one second network side device;

the first network side device receives at least one uplink positioning SRS pre-configuration response from the at least one second network side device, wherein each uplink positioning SRS pre-configuration response carries at least one uplink positioning SRS pre-configuration.

In a specific implementation, the uplink positioning SRS provisioning request may be a request message specially used for requesting uplink positioning SRS provisioning, or may be a request message multiplexing an uplink positioning SRS configuration request in a related technology, and the uplink positioning SRS configuration request carries provisioning indication information to notify a second network side device, so as to feed back the uplink positioning SRS provisioning configured for the terminal to the first network side device.

For example: the LMF can request uplink positioning SRS pre-configuration from a serving cell and an adjacent cell of the terminal, and the request can be carried in a request (Requested) SRS configuration message, so that the serving cell and the adjacent cell can determine the uplink positioning SRS pre-configuration based on the request uplink positioning SRS configuration message, the serving cell sends the determined legacy (legacy) uplink positioning SRS configuration to the terminal through a Radio Resource Control (RRC) message, and sends the uplink positioning SRS configuration (including legacy configuration and pre-configuration) to the LMF, and the adjacent cell only sends the uplink positioning SRS pre-configuration to the LMF. In this way, the LMF may sort all received uplink positioning SRS configurations (including legacy configurations and preconfigurations) to generate an uplink positioning SRS preconfigured set for the terminal.

In an implementation, the uplink positioning SRS pre-configuration set may include a current uplink positioning SRS configuration (legacy configuration) and an uplink positioning SRS pre-configuration of the terminal, and when a serving cell of the terminal is changed or an effective uplink positioning SRS configuration is changed, the terminal does not delete the uplink positioning SRS configuration, the uplink positioning SRS configuration at this time is equivalent to one uplink positioning SRS pre-configuration of the terminal.

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

requesting the type of uplink positioning SRS configuration, wherein the type of the uplink positioning SRS configuration comprises the uplink positioning SRS configuration and uplink positioning SRS pre-configuration;

capability information of the terminal;

a second uplink positioning SRS configuration identifier, where the second uplink positioning SRS configuration identifier is used to distinguish each uplink positioning SRS pre-configuration in the first network side device;

the requested uplink positioning SRS resource set identification information, for example: number of resource sets (resource sets);

the requested uplink positioning SRS resource identification information includes, for example: the number of resource IDs in each resource set;

the requested uplink positioning SRS time domain resource type, for example: periodic, aperiodic or semi-static;

the requested uplink positioning SRS time domain resource is, for example: cycle length, cycle transmission times, etc.;

the requested uplink positioning SRS frequency domain resource is, for example: a frequency domain bandwidth;

the requested uplink positioning SRS spatial association relationship is, for example: spatial association with Synchronization Signal and PBCH block (SSB).

Option one: the capability information of the terminal may be a bandwidth, carrier Aggregation (CA) combination, and the like supported by the terminal, and is used for configuring, by a second network side device, an available SRS resource for the terminal.

And (5) option two: the second uplink positioning SRS configuration identifier may be an LMF SRS config ID, and the LMF SRS config ID may distinguish SRS configurations that the first network side device requests to different second network side devices.

Optionally, the uplink positioning SRS pre-configuration 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 preconfiguration in each second network side device;

effective time for uplink positioning SRS pre-configuration;

a third information field, configured to pre-configure an uplink positioning SRS associated with the third uplink positioning SRS configuration identifier;

a fourth information field, configured to configure, by the third uplink positioning SRS, an effective area for uplink positioning SRS pre-configuration associated with the third uplink positioning SRS configuration identifier.

In an implementation, since one second network-side device may configure multiple uplink positioning SRS preconfigurations for the same terminal, the third uplink positioning SRS configuration identifier may be LMF SRS config ID + RAN SRS config ID, where the uplink positioning SRS preconfigurations configured by the same second network-side device have respective RAN SRS config IDs, so that the first network-side device and the terminal can distinguish the respective uplink positioning SRS preconfigurations by combining the LMF SRS config ID and the RAN SRS config ID.

In addition, the specific meanings and roles of the type, the effective time, the third information field, and the fourth information field of the uplink positioning SRS configuration are the same as the type, the effective time, the first information field, and the second information field of each uplink positioning SRS pre-configuration set in the uplink positioning SRS pre-configuration set, and are not described herein again.

In this embodiment, the existing Requested SRS configuration message may be multiplexed to request the uplink positioning SRS pre-configuration, thereby avoiding resource waste caused by separately sending the uplink positioning SRS pre-configuration request message.

In specific implementation, each terminal has a corresponding uplink positioning SRS pre-configuration set, and following displacement of the terminal, effective uplink positioning SRS pre-configuration for the terminal in the uplink positioning SRS pre-configuration set may change, at this time, the terminal may perform uplink positioning SRS transmission only according to the effective uplink positioning SRS pre-configuration for the terminal, and a positioning related base station may perform corresponding SRS measurement only according to the effective uplink positioning SRS pre-configuration. In order to realize the selection of the uplink positioning SRS pre-configuration effective for the terminal from the uplink positioning SRS pre-configuration set, the following embodiments may be adopted:

implementation mode one

The first network side device can send the uplink positioning SRS pre-configuration set to a corresponding terminal, so that the terminal selects effective uplink positioning SRS pre-configuration from the uplink positioning SRS pre-configuration set according to self conditions, executes the effective uplink positioning SRS pre-configuration, and reports the effective uplink positioning SRS pre-configuration to the first network side device and a current serving cell, thereby enabling a positioning related base station to perform SRS measurement according to the effective uplink positioning SRS pre-configuration.

Optionally, the first uplink positioning SRS configuration method further includes:

the first network side equipment sends the uplink positioning SRS pre-configuration set to the terminal;

the first network side device receives an uplink positioning SRS effective pre-configuration set of the terminal, wherein the uplink positioning SRS effective pre-configuration set comprises identification information of uplink positioning SRS pre-configuration effective to the terminal in the uplink positioning SRS pre-configuration set.

In implementation, the uplink positioning SRS pre-configuration effective for the terminal may be understood as: the terminal is located in the effective area of the uplink positioning SRS pre-configuration, and the uplink positioning SRS pre-configuration is in the effective time. In addition, the identifier information for uplink positioning SRS provisioning effective for the terminal may be understood as a first uplink positioning SRS configuration identifier corresponding to uplink positioning SRS provisioning effective for the terminal.

In addition, in implementation, the receiving, by the first network side device, the effective pre-configured set of the uplink positioning SRS of the terminal may be that the terminal first sends the effective pre-configured set of the uplink positioning SRS to the second network side device, and then the second network side device forwards the effective pre-configured set of the uplink positioning SRS of the terminal to the first network side device, for example: the terminal sends the uplink positioning SRS effective pre-configuration set to the service cell through RRC signaling, and then the service cell sends the uplink positioning SRS effective pre-configuration set to the LMF through NRPPa message. Certainly, in implementation, the effective pre-configuration set of the uplink positioning SRS may also interact among the terminal, the first network side device, and the second network side device in other manners or carried in other messages or signaling, which is not limited specifically herein.

In this embodiment, the first network side device sends the uplink positioning SRS pre-configuration set to the terminal, so that the terminal autonomously determines an effective uplink positioning SRS pre-configuration, and reports the effective uplink positioning SRS pre-configuration set, thereby transmitting a positioning SRS according to the effective uplink positioning SRS pre-configuration, and notifying a positioning related base station to perform corresponding SRS measurement through the first network side device.

Second embodiment

The first network side device and/or the second network side device may also obtain target information reported by the terminal, determine, according to the target information, an effective uplink positioning SRS pre-configuration for the terminal from the uplink positioning SRS pre-configuration set, and notify the terminal to transmit an SRS according to the effective uplink positioning SRS pre-configuration, where the target information may include capability information, location information, and the like of the terminal, and is not specifically limited herein.

It is worth pointing out that, similar to the configuration of the aperiodic or semi-static uplink positioning SRS in the related art, in the case that the uplink positioning SRS is preconfigured to the aperiodic or semi-static SRS, an activation procedure for initiating the aperiodic or semi-static uplink positioning SRS preconfigured may be initiated, for convenience of description, in the following embodiment, an uplink positioning SRS effective set reported by a terminal includes an aperiodic or semi-static uplink positioning SRS effective preconfigured example, and an activation/deactivation procedure for the aperiodic or semi-static uplink positioning SRS preconfigured example is illustrated, and of course, for an implementation manner that the terminal is determined to be effective by using other methods to determine the uplink positioning SRS preconfigured, the aperiodic or semi-static uplink positioning SRS preconfigured may also be activated/deactivated by using a similar procedure, which is not specifically limited herein.

Optionally, the uplink positioning SRS configuration method further includes:

under the condition that the uplink positioning SRS effective pre-configuration set comprises non-periodic or semi-static uplink positioning SRS effective pre-configuration, the first network side equipment sends an uplink positioning SRS configuration activation/deactivation request, wherein the uplink positioning SRS configuration activation/deactivation request comprises identification information of the effective uplink positioning SRS pre-configuration;

and the first network side equipment receives an uplink positioning SRS configuration activation/deactivation response.

In a specific implementation, for effective pre-configuration of an aperiodic or semi-static uplink positioning SRS, before a second network side device performs corresponding SRS measurement, a first network side device sends an uplink positioning SRS configuration activation request to the second network side device to activate a resource corresponding to the effective pre-configuration of the uplink positioning SRS, for example: and the LMF sends an uplink positioning SRS configuration activation request to a serving cell/a resident cell of the terminal, wherein the uplink positioning SRS configuration activation request carries identification information which needs to be activated and is effectively preconfigured by the uplink positioning SRS, so that the serving cell/the resident cell activates corresponding resources which are effectively preconfigured by the uplink positioning SRS, and thus non-periodic or semi-static uplink positioning SRS measurement is realized. Of course, after activating the resource that is effectively preconfigured by the corresponding uplink positioning SRS, if the aperiodic or semi-static uplink positioning procedure is completed, the first network side device may also deactivate the resource that is effectively preconfigured by the uplink positioning SRS, so as to reduce resource waste.

It should be noted that the above procedure for activating/deactivating the aperiodic or semi-static uplink positioning SRS effective pre-configuration is similar to the procedure for activating/deactivating the aperiodic or semi-static uplink positioning SRS configuration in the related art, and the difference is that in the embodiment of the present application, the uplink positioning SRS configuration activation/deactivation request carries identification information of the uplink positioning SRS effective pre-configuration that needs to be activated/deactivated.

Optionally, the uplink positioning SRS configuration activation/deactivation request includes at least one of the following:

the first indication information is used for indicating the activated/deactivated identification information of uplink positioning SRS pre-configuration;

second indication information for indicating the type of the activated/deactivated uplink positioning SRS;

the fifth indication information is used for indicating the activated/deactivated uplink positioning SRS resource identifier;

sixth indication information, configured to indicate an activated/deactivated cell identifier list, where the cell identifier list includes uplink positioning SRS resource configurations corresponding to activated/deactivated SRS pre-configuration;

seventh indication information for indicating an absolute time of activation/deactivation.

In a specific implementation, the identifier information preconfigured by the uplink positioning SRS may be a first uplink positioning SRS configuration identifier. In addition, the sixth indication information is used to indicate an activated/deactivated cell identifier list, so that the corresponding uplink positioning SRS resource configuration may be activated/deactivated in the cell identifier list.

In the embodiment of the application, a first network side device acquires at least one uplink positioning SRS pre-configuration of a terminal from at least one second network side device; and the first network side equipment generates an uplink positioning SRS pre-configuration set of the terminal, wherein the uplink positioning SRS pre-configuration set comprises the at least one uplink positioning SRS pre-configuration. The first network side equipment acquires at least one uplink positioning SRS pre-configuration of the terminal from at least one second network side equipment in advance, and generates an uplink positioning SRS pre-configuration set of the terminal, so that in the uplink positioning process of the terminal, uplink positioning SRS signal transmission can be carried out according to any uplink positioning SRS pre-configuration in the uplink positioning SRS pre-configuration set of the terminal, frequent positioning SRS reconfiguration is avoided, and positioning delay is further shortened.

Please refer to fig. 4, which is a flowchart of a second uplink positioning SRS configuration method according to an embodiment of the present application, where an execution main body of the second uplink positioning SRS configuration method may be a second network side device, and as shown in fig. 4, the second uplink positioning SRS configuration method may include the following steps:

Step 402, the second network side device sends an uplink positioning SRS pre-configuration response to the first network side device, where the uplink positioning SRS pre-configuration response carries at least one uplink positioning SRS pre-configuration of the terminal determined by the second network side device.

It should be noted that, corresponding to the method embodiment shown in fig. 3, the uplink positioning SRS configuration activation/deactivation request and the uplink positioning SRS configuration activation/deactivation response are used to activate/deactivate non-periodic or semi-static uplink positioning SRS configuration resources, and are not described herein again.

Certainly, in implementation, the effective pre-configuration set of the uplink positioning SRS may also interact among the terminal, the first network side device, and the second network side device in other manners or carried in other messages or signaling, which is not limited specifically herein.

In implementation, if the effective pre-configured set of uplink positioning SRS includes identifier information for non-periodic or semi-static uplink positioning SRS pre-configuration, the first network side device may request the second network side device to activate/deactivate the resource for non-periodic or semi-static uplink positioning SRS pre-configuration after receiving the effective pre-configured set of uplink positioning SRS. For example: assuming that the uplink positioning SRS effective preconfigured set of the terminal includes identifier information preconfigured by a first SRS, the first network side device may send an uplink positioning SRS configuration activation request preconfigured for the first SRS to the second network side device according to the identifier information preconfigured by the first SRS in the uplink positioning SRS effective preconfigured set, and activate a resource preconfigured by the first SRS of the terminal according to the uplink positioning SRS configuration activation request, for example: and sending an uplink positioning SRS activation instruction for activating the first SRS pre-configuration to the terminal through MAC/DCI.

Please refer to fig. 5, which is a flowchart of a third uplink positioning SRS configuration method according to an embodiment of the present application, where an execution main body of the third uplink positioning SRS configuration method may be a terminal, and as shown in fig. 5, the third uplink positioning SRS configuration method may include the following steps:

step 501, a terminal receives an uplink positioning SRS pre-configuration set, where the uplink positioning SRS pre-configuration set includes at least one uplink positioning SRS pre-configuration requested by a first network side device to at least one second network side device.

Step 502, the terminal sends an uplink positioning SRS effective preconfigured set, where the uplink positioning SRS effective preconfigured set includes identification information of uplink positioning SRS preconfigured, which is effective for the terminal, in the uplink positioning SRS preconfigured set.

In a specific implementation, the terminal may specifically receive the uplink positioning SRS preconfigured set from a first network side device, report the uplink positioning SRS valid preconfigured set to a second network side device, and forward the uplink positioning SRS valid preconfigured set to the first network side device through the second network side device. Certainly, in implementation, the effective pre-configuration set of the uplink positioning SRS may also interact among the terminal, the first network side device, and the second network side device in other manners or carried in other messages or signaling, which is not limited specifically herein.

The embodiment of the present application corresponds to the method embodiments shown in fig. 3 and 4, and is different in that an execution main body of the method embodiment shown in fig. 3 is a first network-side device, an execution main body of the method embodiment shown in fig. 4 is a second network-side device, and an execution main body of the method embodiment shown in fig. 5 is a terminal, and in the embodiment of the present application, the network-side device configures at least one uplink positioning SRS preconfiguration for the terminal in advance, and the terminal reports an uplink positioning SRS preconfigured valid set when valid uplink positioning SRS preconfiguration changes due to a change of a mobile, a serving cell, or a camped cell, so that the network device performs SRS measurement on an uplink positioning SRS valid for the terminal according to an instruction in the uplink positioning SRS preconfigured set, and/or releases uplink positioning SRS resources and the like corresponding to the invalid uplink positioning preconfigured SRS for the terminal, which may reduce resource waste and unnecessary measurement.

Optionally, the first network side device includes at least one of the following: a Location management function LMF network element, an enhanced Serving Mobile Location Center (eSMLC) and a Secure User Plane Location (SUPL) Platform (SLP);

It should be noted that each option of the first information field and the second information field has the same meaning and function as the corresponding option of the first information field and the second information field in the method embodiment shown in fig. 3, and is not described herein again.

Optionally, the uplink positioning SRS effective preconfigured set further includes at least one of the following:

a cell identity of a serving cell or a camping cell;

and the configuration indication of the uplink positioning SRS without validity is used for indicating that the terminal does not have the valid uplink positioning SRS currently.

In some embodiments, in the absence of an effective uplink positioning SRS pre-configuration for the terminal, the effective uplink positioning SRS pre-configuration set does not include any uplink positioning SRS pre-configuration, and thus an indication of no effective uplink positioning SRS configuration is carried in the effective uplink positioning SRS pre-configuration set to notify a network side device that the current terminal has no effective uplink positioning SRS configuration, and thus an SRS re-configuration process and the like can be triggered. For example: the SRS configuration indication without effective uplink positioning is No Available SRS Config, and the indication is true.

It should be noted that, an effective uplink positioning reference signal configuration identifier may also be carried in the effective uplink positioning SRS preconfigured set, and the effective uplink positioning reference signal configuration identifier may adopt a first uplink positioning SRS configuration identifier (for example, LMF SRS config ID + RAN SRS config ID) preconfigured to the effective uplink positioning SRS of the terminal, so that, when the effective uplink positioning SRS configuration identifier is null, it may be understood that there is no uplink positioning SRS preconfigured to the terminal in the effective uplink positioning SRS preconfigured set.

In addition, the cell identifier of the serving cell or the camped cell may be a cell ID such as a PCI or a CGI. In this way, when it is determined that the effective uplink positioning SRS pre-configuration set does not include the effective uplink positioning SRS pre-configuration for the terminal, the first network side device may request, according to the cell identifier of the serving cell or the camping cell, the serving cell or the camping cell to configure a new uplink positioning SRS configuration for the terminal.

As an optional implementation manner, the sending, by the terminal, an effective pre-configured set of an uplink positioning SRS, includes:

the serving cell of the terminal has changed;

the resident cell of the terminal is changed;

the terminal detects a positioning requirement event trigger.

In a specific implementation, the uplink positioning SRS effective preconfigured set may trigger reporting when at least one of the above conditions is met, so that the terminal reduces a frequency of reporting the uplink positioning SRS effective preconfigured set while reporting the uplink positioning SRS effective preconfigured set in time, thereby reducing resource consumption.

As an optional implementation manner, after the terminal sends the effective pre-configured set of uplink positioning SRS, the method further includes:

the terminal receives an uplink positioning SRS configuration activation/deactivation indication;

and the terminal activates/deactivates the uplink positioning SRS configuration in the uplink positioning SRS effective pre-configuration set according to the uplink positioning SRS configuration activation/deactivation indication.

In implementation, if the effective pre-configuration set of the uplink positioning SRS includes identification information of aperiodic or semi-static uplink positioning SRS pre-configuration, the first network side device may request the second network side device to activate/deactivate the aperiodic or semi-static uplink positioning SRS pre-configuration after acquiring the effective pre-configuration set of the uplink positioning SRS, so that the second network side device may send the uplink positioning SRS configuration activation/deactivation instruction to the terminal according to the request.

It should be noted that, different from the activation/deactivation indication of the uplink positioning SRS configuration in the related art, the activation/deactivation indication of the uplink positioning SRS configuration in the embodiment of the present application carries identification information of the uplink positioning SRS configuration that needs to be activated/deactivated, for example: a first uplink positioning SRS configuration identifier (for example, LMF SRS config ID + RAN SRS config ID) configured by the uplink positioning SRS.

Optionally, the uplink positioning SRS configuration activation/deactivation indication includes at least one of the following:

second indication information, configured to indicate a type of the activated/deactivated uplink positioning SRS;

and sixth indication information, configured to indicate an activated/deactivated cell identifier list, where the cell identifier list includes uplink positioning SRS resource configurations corresponding to activated/deactivated SRS pre-configuration.

It should be noted that each option of the uplink positioning SRS configuration activation/deactivation indication has the same meaning as the corresponding option of the uplink positioning SRS configuration activation/deactivation request in the embodiment of the method shown in fig. 3, and is not described herein again.

The uplink positioning SRS configuration method performed by the terminal according to the embodiment of the present application is matched with the uplink positioning SRS configuration method performed by the network side device as shown in fig. 3 and fig. 4, so as to jointly achieve the effects of reducing the positioning SRS reconfiguration probability and shortening the positioning delay, which is not described herein again.
