The 5G NR introduces a variety of positioning techniques for achieving positioning of a terminal. For uplink positioning, an uplink positioning reference signal is sent to the network equipment through the terminal, so that the positioning of the network equipment to the terminal is realized. For the aperiodic uplink positioning reference signal and the semi-persistent uplink positioning reference signal, the network device is required to activate or deactivate the uplink positioning reference signal configured for the terminal. The network device activates or deactivates the uplink positioning reference signal configured for the terminal by sending an activation command or a deactivation command of the uplink positioning reference signal to the terminal. After receiving the activation instruction (activation command), the terminal starts to send the uplink positioning reference signal, and after receiving the deactivation instruction (deactivation command), the terminal stops sending the uplink positioning reference signal.

Fig. 1 is a schematic diagram illustrating an activation or deactivation manner of an uplink positioning reference signal according to an exemplary embodiment of the present application. As shown in fig. 1, in step 0, the related device performs a procedure of new air interface positioning protocol a (NRPPa) transmitting reception point (Transmission Reception Point, TRP) configuration information exchange (NRPPa TRP Configuration Information Exchange). In step 1, the associated device performs a long term evolution positioning protocol (LPP) capability transfer (LPP Capability Transfer) procedure. In step 2, the location management function (Location Management Function, LMF) network element sends a new air interface positioning protocol a location information request to the serving base station or sending receiving point of the terminal (NRPPa POSITIONING INFORMATION REQUEST). In step 3, the base station determines uplink sounding reference signal resources (gNB determines UL SRS Resources). In step 3a, the base station or transmission reception point of the terminal transmits the sounding reference signal configuration of the terminal to the terminal (UE SRS configuration). In step 4, the base station or the transmitting/receiving point of the terminal transmits a new air interface positioning protocol a positioning information response to the LMF network element (NRPPa POSITIONING INFORMATION RESPONSE). In step 5a, the LMF network element sends a new air interface positioning protocol a positioning activation request to the base station or sending receiving point of the terminal (NRPPa POSITIONING ACTIVATION REQUEST). In step 5b, the base station or the transmitting/receiving point of the terminal performs sounding reference signal transmission of the active state terminal to the terminal (Activate UE SRS transmission). In step 5c, the base station or the transmitting/receiving point of the terminal transmits a new air interface positioning protocol a positioning activation response to the LMF network element (NRPPa POSITIONING ACTIVATION RESPONSE). In step 6, the LMF network element sends a new air interface positioning protocol a measurement request to the base station or sending receiving point (NRPPa MEASUREMENT REQUEST). In step 7, the base station or the transmission/reception point performs uplink sounding reference signal measurement (UL SRS Measurements). In step 8, the base station or the transmitting/receiving point transmits a new air interface positioning protocol a measurement response to the LMF network element (NRPPa MEASUREMENT RESPONSE). In step 9, the LMF network element performs new air interface positioning protocol a positioning deactivation on the base station or the transmitting and receiving point of the terminal (NRPPa POSITIONING DEACTIVATION).

As shown in fig. 1, when the base station receives the activation/deactivation instruction of the uplink positioning reference signal sent by the LMF network element (5 a, 9), the base station sends an activation command or a deactivation command to the terminal. Specifically, for the semi-persistent uplink positioning reference signal, the base station sends an activation command or a deactivation command through a medium access control layer control element (Media Access Control Control Element, MAC CE). For aperiodic uplink positioning reference signals, the base station transmits an activation command or a deactivation command through downlink control information (Downlink Control Information, DCI).

In R17 of the third generation partnership project (3rd Generation Partnership Project,3GPP), localization of inactive terminals is introduced. For an inactive terminal, only semi-persistent uplink positioning reference signals are supported, and the uplink positioning reference signals are activated/deactivated in the following manners:

if there is an ongoing small data transfer (Small Data Transmission, SDT), the base station may send an activate command to the inactive terminal, the SDT being triggered by the terminal;

when the base station configures an uplink positioning reference signal to the terminal through a radio resource control (Radio Resource Control, RRC) release message, the base station may send an activation command to the terminal;

If there is an ongoing SDT, the base station can send a deactivation command to the inactive terminal.

For R18 of 3GPP, there is a need for low power consumption and high accuracy (Low Power High Accuracy, LPHA) positioning, i.e. the power consumption of terminal positioning needs to be reduced, and positioning of idle state (idle) terminals may be introduced.

When the base station configures the uplink positioning reference signal to the terminal through the RRC release message, the base station needs to send an activation command of the uplink positioning reference signal to the terminal, and at this time, the LMF network element may not send an activation command to the base station, so that the power consumption of the terminal is increased by making the terminal send the uplink positioning reference signal in advance. For an idle terminal, SDT may not be supported, and then an activation command or a deactivation command cannot be sent to the terminal by way of SDT, so that the idle terminal needs to be transferred to a connected state (connected) and then send the activation command or the deactivation command to the terminal, which also increases the power consumption of the terminal.

According to the method provided by the embodiment of the application, the network triggering-small data transmission (Mobile Terminated-SDT, MT-SDT) process is triggered through the network equipment, so that an activation command or a deactivation command of an uplink positioning reference signal is sent to the terminal in the MT-SDT process. Compared with the existing method that the terminal triggers the SDT, the network equipment can send the activation command or the deactivation command after the terminal triggers the SDT, so that the method can flexibly send the activation command or the deactivation command to the terminal on the basis of the SDT as required without waiting for the terminal to trigger the SDT. The method provided by the embodiment of the application also sends the activation command or the deactivation command of the uplink positioning reference signal to the terminal through the paging message. The method can realize that the activation command or the deactivation command is sent to the terminal as required, and avoid sending the activation command to the terminal before the LMF network element sends the activation command to the base station, namely before uplink positioning is started, thereby avoiding the terminal from sending the uplink positioning reference signal before the uplink positioning is started, and realizing the reduction of the power consumption of the terminal. The method provided by the embodiment of the application further transmits an activation command or a deactivation command of the uplink positioning reference signal to the terminal in the non-connection state (including the non-activation state and the idle state) through the DCI. The activation command or the deactivation command can be sent to the terminal in the non-connection state through DCI according to the requirement.

The names of access network device-capable devices may vary in systems employing different radio access technologies, for example in 5G NR systems, called gndeb or gNB. As communication technology evolves, the name "access network device" may change. For convenience of description, in the embodiment of the present application, the above-mentioned devices for providing the terminal 201 with a wireless communication function are collectively referred to as an access network device. A connection may be established between the access network device 202 and the terminal 201 over an air interface, such that communication, including interaction of signaling and data, is performed over the connection. The number of access network devices 202 may be plural, and communication between two adjacent access network devices 202 may be performed by wired or wireless means. The terminal 201 may switch between different access network devices 202, i.e. establish a connection with different access network devices 202.

The core network device 203 mainly functions to provide user connection, management of users, and bearer completion of services, and provides an interface to an external network as a bearer network. The access network device 202 and the core network device 203 may be collectively referred to as network devices. The core network device 203 and the access network device 202 communicate with each other via some over-the-air technology, and a communication relationship can be established between the terminal 201 and the core network device 203 via the access network device 202.

The "5G NR system" in the embodiments of the present application may also be referred to as a 5G system or an NR system, but a person skilled in the art may understand the meaning thereof. The technical scheme described in the embodiment of the application can be applied to a 5G NR system and also can be applied to a subsequent evolution system of the 5G NR system.

Fig. 3 is a flow chart illustrating a method for activating or deactivating an uplink positioning reference signal according to one embodiment of the present application. The method can be applied to network equipment. The method comprises the following steps:

step 302: and in the MT-SDT process triggered by the network equipment, sending an activation command or a deactivation command of the uplink positioning reference signal to the terminal.

The MT-SDT process is triggered by the network equipment, and the network equipment can send an activation command or a deactivation command of the uplink positioning reference signal to the terminal through resources corresponding to the MT-SDT according to requirements in the MT-SDT process after triggering the MT-SDT process.

For example, the network device configures an uplink positioning reference signal to the terminal through an RRC release message, i.e. sends the configuration of the uplink positioning reference signal to the terminal. And after receiving the activation instruction of the uplink positioning reference signal sent by the LMF network element, the network equipment triggers the MT-SDT process and sends an activation command of the uplink positioning reference signal to the terminal through resources corresponding to the MT-SDT. Or after the network equipment receives the deactivation instruction of the uplink positioning reference signal sent by the LMF network element, triggering the MT-SDT process, and sending a deactivation command of the uplink positioning reference signal to the terminal through resources corresponding to the MT-SDT.

Optionally, the network device supports triggering the MT-SDT procedure for the idle terminal, and sends an activation command or a deactivation command of the uplink positioning reference signal to the idle terminal through a resource corresponding to the MT-SDT.

Optionally, in the MT-SDT procedure, the network device sends an activation command or a deactivation command of the uplink positioning reference signal to the terminal through a downlink configuration Grant-small data transfer (CG-SDT) resource or a Random Access-small data transfer (RA-SDT) resource.

After receiving the message that the network device triggers the MT-SDT, the terminal can receive an activation command or a deactivation command of an uplink positioning reference signal sent by the network device to the terminal in the MT-SDT process.

In summary, according to the method provided in this embodiment, the network device triggers the MT-SDT process, so that the activation command or the deactivation command of the uplink positioning reference signal is sent to the terminal in the MT-SDT process, which can implement that the terminal does not need to wait for triggering the SDT, and flexibly send the activation command or the deactivation command to the terminal based on the SDT as required.

Fig. 4 is a flowchart of a method for activating or deactivating an uplink positioning reference signal according to an embodiment of the present application. The method can be applied to network equipment. The method comprises the following steps:

step 402: and sending a paging message to the terminal, wherein the paging message carries an activation command or a deactivation command of the uplink positioning reference signal.

The paging message is a message for the network device to transmit an activation command or a deactivation command of the uplink positioning reference signal to the terminal. After the network device sends the paging message to the terminal, the terminal may receive an activation command or a deactivation command of the uplink positioning reference signal, so as to activate the uplink positioning reference signal or deactivate the uplink positioning reference signal according to the received command.

Optionally, the paging message further carries at least one of the following information:

uplink positioning reference signal resource identification;

Terminal identification.

The uplink positioning reference signal resource identifier is used for identifying a resource (time-frequency resource) corresponding to the uplink positioning reference signal, and the terminal identifier is used for identifying a terminal. Optionally, the uplink positioning reference signal resource identifier includes at least one of the following:

partial bandwidth identification (Positioning SRS Resource Set's BWP ID) of the set of positioning reference signal resources;

-positioning reference signal resource set identification (Positoining SRS Resource Set ID);

spatial relationship of resource identification (Spatial Relation for Resource ID);

cell identity (Positioning SRS Resource Set's Cell ID) of the set of positioning reference signal resources.

After receiving the paging message which also carries the uplink positioning reference signal resource identifier and/or the terminal identifier, the terminal determines whether to activate the uplink positioning reference signal configured for the terminal or whether to deactivate the uplink positioning reference signal configured for the terminal. The following three cases are specifically classified:

for the case that the paging message carries the uplink positioning reference signal resource identifier:

in this case, the paging message is used to indicate that the terminal activates the uplink positioning reference signal according to the activation command or deactivates the uplink positioning reference signal according to the deactivation command, in the case that the resource identifier in the uplink positioning reference signal configuration of the terminal is the same as the uplink positioning reference signal resource identifier.

For example, if the paging message includes an activation command or a deactivation command and the paging message includes an uplink positioning reference signal resource identifier, the terminal compares the uplink positioning reference signal resource identifier with a resource identifier (for identifying a resource corresponding to the uplink positioning reference signal configuration) in at least one uplink positioning reference signal configuration of the terminal. If the two are the same, the terminal activates or deactivates the uplink positioning reference signal (uplink positioning reference signal configuration) corresponding to the uplink positioning reference signal resource identifier.

For the case that the paging message carries the terminal identifier:

in this case, the paging message is used to indicate that the terminal activates the uplink positioning reference signal according to the activation command or deactivates the uplink positioning reference signal according to the deactivation command in case that the identity of the terminal is the same as the terminal identity.

For example, if the paging message contains an activation command or a deactivation command and the paging message contains a terminal identity, the terminal will compare the terminal identity with the identity of the terminal itself. If the two are the same, the terminal activates or deactivates all its uplink positioning reference signals (uplink positioning reference signal configuration).

It should be noted that, for the current paging message, it can also include a terminal identifier. After receiving the current paging message, if the terminal determines that the identifier of the terminal is in the paging message, the terminal monitors a physical downlink control channel (Physical Downlink Control Channel, PDCCH) so as to receive downlink data. The current paging message may also be regarded as an existing paging message, where the current paging message is a paging message that does not carry an activation command or a deactivation command of the uplink positioning reference signal.

In addition, the terminal identifier in the present paging message is different from the terminal identifier in the above paging message in the embodiment of the present application. The terminal can determine that the paging message is used for activating or deactivating the uplink positioning reference signal through the terminal identifier in the paging message in the embodiment of the present application, but is not used for indicating that there is downlink data sent to the terminal.

Aiming at the situation that the paging message carries the uplink positioning reference signal resource identifier and the terminal identifier:

in this case, the paging message is used to indicate that the resource identifier in the uplink positioning reference signal configuration of the terminal is the same as the uplink positioning reference signal resource identifier, and in the case that the identifier of the terminal is the same as the terminal identifier, the terminal activates the uplink positioning reference signal according to the activation command, or deactivates the uplink positioning reference signal according to the deactivation command.

For example, if the paging message includes an activation command or a deactivation command and the paging message includes an uplink positioning reference signal resource identifier and a terminal identifier, the terminal compares the uplink positioning reference signal resource identifier with a resource identifier in at least one uplink positioning reference signal configuration of the terminal and compares the terminal identifier with an identifier of the terminal itself. If the resource identifier of the uplink positioning reference signal is the same as the resource identifier in at least one uplink positioning reference signal configuration of the terminal, and the terminal identifier is the same as the identifier of the terminal itself, the terminal activates or deactivates the uplink positioning reference signal (uplink positioning reference signal configuration) corresponding to the uplink positioning reference signal resource identifier.

In summary, in the method provided in this embodiment, the activation command or the deactivation command of the uplink positioning reference signal is sent to the terminal through the paging message. The method can realize that the activation command or the deactivation command is sent to the terminal as required, and avoid sending the activation command to the terminal before the LMF network element sends the activation command to the base station, namely before uplink positioning is started, thereby avoiding the terminal from sending the uplink positioning reference signal before the uplink positioning is started, and realizing the reduction of the power consumption of the terminal.

Fig. 5 is a flowchart of a method for activating or deactivating an uplink positioning reference signal according to an embodiment of the present application. The method can be applied to network equipment. The method comprises the following steps:

step 502: and sending DCI to the terminal, wherein the DCI carries an activation command or a deactivation command of the uplink positioning reference signal.

The terminal is in a non-connected state, which includes an idle state and a non-active state. The DCI is a message for a network device to transmit an activation command or a deactivation command of an uplink positioning reference signal to a non-connected state terminal. After the network device sends the DCI to the non-connected terminal, the non-connected terminal may receive an activation command or a deactivation command of the uplink positioning reference signal, so as to activate the uplink positioning reference signal or deactivate the uplink positioning reference signal according to the received command.

Optionally, the DCI is at least one of:

DCI format 1_0 (DCI format 1_0);

DCI scrambled by Paging radio network temporary identity (Paging-Radio Network Temporary Identity, P-RNTI);

DCI scrambled by a system information radio network temporary identity (System Information-Radio Network Temporary Identity, SI-RNTI).

Optionally, the DCI also carries an uplink positioning reference signal resource identifier. The uplink positioning reference signal resource identifier is used for identifying a resource (time-frequency resource) corresponding to the uplink positioning reference signal. Optionally, the uplink positioning reference signal resource identifier includes at least one of the following:

·Positioning SRS Resource Set's BWP ID；

·Positoining SRS Resource Set ID；

·Spatial Relation for Resource ID；

·Positioning SRS Resource Set's Cell ID。

after receiving the DCI which also carries the uplink positioning reference signal resource identifier, the terminal determines whether to activate the uplink positioning reference signal configured for the terminal or whether to deactivate the uplink positioning reference signal configured for the terminal.

The DCI is used for indicating that the terminal activates the uplink positioning reference signal according to the activation command or deactivates the uplink positioning reference signal according to the deactivation command under the condition that the resource identifier in the uplink positioning reference signal configuration of the terminal is the same as the uplink positioning reference signal resource identifier.

For example, if the DCI includes an activation command or a deactivation command and the DCI includes an uplink positioning reference signal resource identity, the terminal compares the uplink positioning reference signal resource identity with a resource identity in at least one uplink positioning reference signal configuration of the terminal. If the two are the same, the terminal activates or deactivates the uplink positioning reference signal (uplink positioning reference signal configuration) corresponding to the uplink positioning reference signal resource identifier.

In summary, according to the method provided in this embodiment, the activation command or the deactivation command of the uplink positioning reference signal is sent to the terminal in the non-connected state through the DCI, so that the activation command or the deactivation command can be sent to the terminal in the non-connected state through the DCI as required.

Fig. 6 is a flow chart illustrating a method for activating or deactivating an uplink positioning reference signal according to one embodiment of the present application. The method can be applied to the terminal. The method comprises the following steps:

step 602: and in the MT-SDT process triggered by the network equipment, receiving an activation command or a deactivation command of an uplink positioning reference signal sent by the network equipment.

Optionally, in the MT-SDT procedure, the network device sends an activation command or a deactivation command of the uplink positioning reference signal to the terminal through the CG-SDT resource or the RA-SDT resource. The terminal receives an activation command or a deactivation command sent by the network device through the CG-SDT resource or the RA-SDT resource.

Fig. 7 is a flowchart of a method for activating or deactivating an uplink positioning reference signal according to an embodiment of the present application. The method can be applied to the terminal. The method comprises the following steps:

Step 702: and receiving a paging message sent by the network equipment, wherein the paging message carries an activation command or a deactivation command of the uplink positioning reference signal.

uplink positioning reference signal resource identification;

terminal identification.

·Positioning SRS Resource Set's BWP ID；

·Positoining SRS Resource Set ID；

·Spatial Relation for Resource ID；

·Positioning SRS Resource Set's Cell ID。
