5G NR introduces a variety of positioning technologies to achieve positioning of terminals. For uplink positioning, the terminal sends an uplink positioning reference signal to the network device, thereby realizing the positioning of the terminal by the network device. Among them, for the aperiodic uplink positioning reference signal and the semi-persistent uplink positioning reference signal, the network device needs 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 deactivation command of the uplink positioning reference signal to the terminal. After the terminal receives the activation instruction (activation command), it will start sending the uplink positioning reference signal. After the terminal receives the deactivation instruction (deactivation command), it will stop sending the uplink positioning reference signal.

Exemplarily, FIG. 1 is a schematic diagram of an activation or deactivation method of an uplink positioning reference signal provided by an exemplary embodiment of the present application. As shown in Figure 1, in step 0, the relevant equipment performs the process of New Radio Positioning Protocol A (NRPPa) Transmission Reception Point (TRP) configuration information exchange (NRPPa TRP Configuration Information Exchange). In step 1, the relevant equipment performs the process of Long Term Evolution Positioning Protocol (LPP) capability transfer (LPP Capability Transfer). In step 2, the Location Management Function (LMF) network element sends a New Air Interface Positioning Protocol A positioning information request (NRPPa POSITIONING INFORMATION REQUEST) to the terminal's service base station or transmitting and receiving point. In step 3, the base station determines the uplink sounding reference signal resources (gNB determines UL SRS Resources). In step 3a, the terminal's base station or transmitting and receiving point sends the terminal's sounding reference signal configuration (UE SRS configuration) to the terminal. In step 4, the terminal's base station or transmitting and receiving point sends a New Air Interface Positioning Protocol A positioning information response (NRPPa POSITIONING INFORMATION RESPONSE) to the LMF network element. In step 5a, the LMF network element sends a New Air Interface Positioning Protocol A positioning activation request (NRPPa POSITIONING ACTIVATION REQUEST) to the base station or transmitting and receiving point of the terminal. In step 5b, the base station or transmitting and receiving point of the terminal performs the detection reference signal transmission of the activated terminal (Activate UE SRS transmission) to the terminal. In step 5c, the terminal's base station or transmitting and receiving point sends a new air interface positioning protocol A positioning activation response (NRPPa POSITIONING ACTIVATION RESPONSE) to the LMF network element. In step 6, the LMF network element sends a New Air Interface Positioning Protocol A measurement request (NRPPa MEASUREMENT REQUEST) to the base station or transmitting and receiving point. In step 7, the base station or transmitting and receiving point performs uplink sounding reference signal measurements (UL SRS Measurements). In step 8, the base station or transmitting and receiving point sends the New Air Interface Positioning Protocol A measurement response (NRPPa MEASUREMENT RESPONSE) to the LMF network element. In step 9, the LMF network element performs New Air Interface Positioning Protocol A positioning deactivation (NRPPa POSITIONING DEACTIVATION) on the base station or transmitting and receiving point of the terminal.

As shown in Figure 1, when the base station receives the activation/deactivation indication (5a, 9) of the uplink positioning reference signal sent by the LMF network element, the base station will send 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 the Media Access Control Layer Control Element (MAC CE). For aperiodic uplink positioning reference signals, the base station sends activation commands or deactivation commands through downlink control information (DCI).

In R17 of the 3rd Generation Partnership Project (3GPP), the positioning of inactive terminals was introduced. For inactive terminals, it only supports semi-persistent uplink positioning reference signals. The method of activating/deactivating the uplink positioning reference signals is:

If there is ongoing Small Data Transmission (SDT), the base station can send an activation command to the inactive terminal. The SDT is triggered by the terminal;

When the base station configures the uplink positioning reference signal to the terminal through the Radio Resource Control (RRC) release message, the base station can 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, the requirement for low power high accuracy (LPHA) positioning is proposed, that is, the power consumption of terminal positioning needs to be reduced, and the positioning of 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 the activation command of the uplink positioning reference signal to the terminal. Since the LMF network element may not have sent the activation command to the base station at this time, it requires the terminal to send the uplink positioning reference signal in advance. Positioning reference signals will increase the power consumption of the terminal. For idle terminals, SDT may not be supported, so activation commands or deactivation commands cannot be sent to the terminal through SDT. Therefore, the idle terminal needs to be transferred to the connected state (connected) before sending activation commands or deactivation commands to the terminal. This It will also increase the power consumption of the terminal.

The method provided by the embodiment of the present application triggers the network trigger-small data transmission (Mobile Terminated-SDT, MT-SDT) process through the network device, thereby sending an activation command of the uplink positioning reference signal to the terminal during the MT-SDT process or Deactivate the command. Compared with the existing method of triggering SDT by the terminal, the network device can only send activation commands or deactivation commands after the terminal triggers SDT. This method can flexibly send activation commands or deactivation commands to the terminal based on SDT without waiting for the terminal to trigger SDT. Deactivate the command. The method provided by the embodiment of the present application also sends an activation command or deactivation command of the uplink positioning reference signal to the terminal through a paging message. It is possible to send activation commands or deactivation commands to the terminal on demand to avoid sending activation commands to the terminal before the LMF network element sends the activation command to the base station, that is, before starting uplink positioning, thereby preventing the terminal from sending uplink positioning before starting uplink positioning. Reference signal to reduce terminal power consumption. The method provided by the embodiment of the present application also sends an activation command or deactivation command of the uplink positioning reference signal to a terminal in a non-connected state (including an inactive state and an idle state) through DCI. It is possible to send activation commands or deactivation commands to non-connected terminals on demand through DCI.

The access network device 202 is a device deployed in the access network to provide wireless communication functions for the terminal 201. Access network equipment 202 may include various forms of macro base stations, micro base stations, relay stations, and access points. In systems using different wireless access technologies, the names of devices with access network device functions may be different. For example, in 5G NR systems, they are called gNodeB or gNB. As communication technology evolves, the name "access network equipment" may change. For convenience of description, in the embodiment of the present application, the above-mentioned devices that provide wireless communication functions for the terminal 201 are collectively referred to as access network equipment. A connection can be established between the access network device 202 and the terminal 201 through an air interface, so that communication, including signaling and data interaction, can be performed through the connection. The number of access network devices 202 may be multiple, and communication between two adjacent access network devices 202 may also be carried out in a wired or wireless manner. The terminal 201 can switch between different access network devices 202, that is, establish connections with different access network devices 202.

The functions of the core network equipment 203 are mainly to provide user connections, manage users, and carry services, and serve as a bearer network to provide an interface to an external network. Access network equipment 202 and core network equipment 203 may be collectively referred to as network equipment. The core network device 203 and the access network device 202 communicate with each other through some kind of air technology. Through the access network device 202, a communication relationship can be established between the terminal 201 and the core network device 203.

Figure 3 shows a flow chart of a method for activating or deactivating an uplink positioning reference signal provided by an embodiment of the present application. This method can be applied to network equipment. The method includes:

Step 302: In the MT-SDT process triggered by the network device, send an activation command or deactivation command of the uplink positioning reference signal to the terminal.

The MT-SDT process is triggered by the network device. After triggering the MT-SDT process, the network device can send an activation command or deactivation command of the uplink positioning reference signal to the terminal through the resources corresponding to MT-SDT according to the needs during the MT-SDT process. Activate command.

For example, the network device configures the uplink positioning reference signal to the terminal through the RRC release message, that is, it sends the uplink positioning reference signal configuration to the terminal. Later, after the network device receives the activation indication of the uplink positioning reference signal sent by the LMF network element, it will trigger the MT-SDT process and send the activation command of the uplink positioning reference signal to the terminal through the resources corresponding to MT-SDT. Alternatively, after the network device receives the deactivation instruction of the uplink positioning reference signal sent by the LMF network element, it will trigger the MT-SDT process and send the deactivation command of the uplink positioning reference signal to the terminal through the resources corresponding to MT-SDT.

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

Optionally, during the MT-SDT process, the network device configures the downlink grant-small data transmission (Configure Grant-SDT, CG-SDT) resource or the random access-small data transmission (Random Access-SDT, RA-SDT) resources to send the activation command or deactivation command of the uplink positioning reference signal to the terminal.

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

In summary, the method provided in this embodiment triggers the MT-SDT process through the network device, thereby sending the activation command or deactivation command of the uplink positioning reference signal to the terminal during the MT-SDT process, so that there is no need to wait for the terminal to trigger SDT, flexibly sends activation commands or deactivation commands to the terminal based on SDT on demand.

Figure 4 shows a flow chart of a method for activating or deactivating an uplink positioning reference signal provided by an embodiment of the present application. This method can be applied to network equipment. The method includes:

Step 402: Send a paging message to the terminal, where the paging message carries an activation command or a deactivation command for the uplink positioning reference signal.

The paging message is a message used by the network device to send 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 can receive the activation command or deactivation command of the uplink positioning reference signal, thereby activating or deactivating the uplink positioning reference signal according to the received command.

Optionally, the paging message also 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 to identify resources (time-frequency resources) corresponding to the uplink positioning reference signal, and the terminal identifier is used to identify the terminal. Optionally, the uplink positioning reference signal resource identifier includes at least one of the following:

·Partial bandwidth identification of the positioning reference signal resource set (Positioning SRS Resource Set's BWP ID);

·Positoining SRS Resource Set ID);

·Spatial Relation for Resource ID;

·The cell ID of the positioning reference signal resource set (Positioning SRS Resource Set's Cell ID).

After receiving the paging message that 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 it or whether to deactivate the uplink positioning reference signal configured for it. Specifically, it can be divided into the following three situations:

For the situation where the paging message carries the uplink positioning reference signal resource identifier:

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

For example, if the paging message contains an activation command or a deactivation command, and the paging message contains an uplink positioning reference signal resource identifier, the terminal will combine the uplink positioning reference signal resource identifier with at least one resource identifier in the uplink positioning reference signal configuration of the terminal. (used to identify the resources corresponding to the uplink positioning reference signal configuration) for comparison. If the two are the same, the terminal will activate or deactivate the uplink positioning reference signal (uplink positioning reference signal configuration) corresponding to the uplink positioning reference signal resource identifier.

For the situation where 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 when the terminal identifier is the same as the terminal identifier.

For example, if the paging message contains an activation command or a deactivation command, and the paging message contains a terminal identifier, the terminal will compare the terminal identifier with the terminal's own identifier. If the two are the same, the terminal will activate or deactivate all its uplink positioning reference signals (uplink positioning reference signal configuration).

It should be noted that the current paging message can also include the terminal identifier. After receiving the current paging message, if the terminal determines that the terminal's identity is in the paging message, the terminal will monitor the Physical Downlink Control Channel (PDCCH) to receive downlink data. The current paging message can also be regarded as an existing paging message. 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 current paging message is different from the terminal identifier in the above paging message in the embodiment of the present application. Through the terminal identifier in the paging message in the embodiment of the present application, the terminal can determine that the paging message is used to activate or deactivate the uplink positioning reference signal, rather than indicating the presence of downlink data sent to the terminal.

For the situation where the paging message carries the uplink positioning reference signal resource identifier and terminal identifier:

In this case, the paging message is used to indicate that when the resource identifier in the terminal's uplink positioning reference signal configuration is the same as the uplink positioning reference signal resource identifier, and the terminal's identifier is the same as the terminal identifier, the terminal activates the uplink according to the activation command. Positioning reference signal, or deactivating the uplink positioning reference signal according to the deactivation command.

For example, if the paging message contains an activation command or a deactivation command, and the paging message contains an uplink positioning reference signal resource identifier and a terminal identifier, the terminal will configure the uplink positioning reference signal resource identifier with at least one uplink positioning reference signal of the terminal. Compare the resource identifier of the resource identifier, and compare the terminal identifier with the identifier of the terminal itself. If the uplink positioning reference signal resource identifier 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 terminal's own identifier, the terminal will activate or deactivate the uplink positioning reference signal resource identifier corresponding to The uplink positioning reference signal (uplink positioning reference signal configuration).

To sum up, the method provided in this embodiment sends an activation command or a deactivation command of the uplink positioning reference signal to the terminal through a paging message. It is possible to send activation commands or deactivation commands to the terminal on demand to avoid sending activation commands to the terminal before the LMF network element sends the activation command to the base station, that is, before starting uplink positioning, thereby preventing the terminal from sending uplink positioning before starting uplink positioning. Reference signal to reduce terminal power consumption.

Figure 5 shows a flow chart of a method for activating or deactivating an uplink positioning reference signal provided by an embodiment of the present application. This method can be applied to network equipment. The method includes:

Step 502: Send DCI to the terminal, where the DCI carries the activation command or deactivation command of the uplink positioning reference signal.

The terminal is in a non-connected state, which includes idle state and inactive state. The DCI is a message used by the network device to send an activation command or deactivation command of the uplink positioning reference signal to the non-connected terminal. After the network device sends the DCI to the non-connected terminal, the non-connected terminal can receive the activation command or deactivation command of the uplink positioning reference signal, thereby activating the uplink positioning reference signal or deactivating the uplink positioning reference according to the received command. Signal.

Optionally, the DCI is at least one of the following:

·DCI format 1_0(DCI format 1_0);

·DCI scrambled by Paging-Radio Network Temporary Identity (P-RNTI);

·DCI scrambled by 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 to identify resources (time-frequency resources) 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 that also carries the uplink positioning reference signal resource identifier, the terminal will determine whether to activate the uplink positioning reference signal configured for it or whether to deactivate the uplink positioning reference signal configured for it.

This DCI is used to indicate that when the resource identifier in the terminal's uplink positioning reference signal configuration is the same as the uplink positioning reference signal resource 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 DCI contains an activation command or a deactivation command, and the DCI contains an uplink positioning reference signal resource identifier, the terminal will compare the uplink positioning reference signal resource identifier with the resource identifier in at least one uplink positioning reference signal configuration of the terminal. . If the two are the same, the terminal will activate or deactivate the uplink positioning reference signal (uplink positioning reference signal configuration) corresponding to the uplink positioning reference signal resource identifier.

In summary, the method provided in this embodiment can send an activation command or a deactivation command of the uplink positioning reference signal to a terminal in a non-connected state through DCI, so that the activation command or deactivation command can be sent to a terminal in a non-connected state on demand through DCI. Activate command.

Step 602: During the MT-SDT process triggered by the network device, receive the activation command or deactivation command of the uplink positioning reference signal sent by the network device.

Optionally, during the MT-SDT process, the network device sends an activation command or deactivation command of the uplink positioning reference signal to the terminal through CG-SDT resources or RA-SDT resources. The terminal will receive the activation command or deactivation command sent by the network device through the CG-SDT resource or RA-SDT resource.

·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.

When the resource identifier in the terminal's uplink positioning reference signal configuration is the same as the uplink positioning reference signal resource 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 the situation where the paging message carries the terminal identifier:

When 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.

When the resource identifier in the terminal's uplink positioning reference signal configuration is the same as the uplink positioning reference signal resource identifier, and the terminal identifier is the same as the terminal identifier, the terminal activates the uplink positioning reference signal according to the activation command, or deactivates it according to the deactivation command.

Figure 8 shows a flow chart of a method for activating or deactivating an uplink positioning reference signal provided by an embodiment of the present application. This method can be applied in the terminal. The method includes:

Step 802: Receive the DCI sent by the network device. The DCI carries the activation command or deactivation command of the uplink positioning reference signal.

Optionally, the DCI is at least one of the following:

·DCI format 1_0;

·DCI scrambled by P-RNTI;

·DCI scrambled by SI-RNTI.

·Positioning SRS Resource Set's BWP ID;

·Positoining SRS Resource Set ID;

·Spatial Relation for Resource ID;

·Positioning SRS Resource Set's Cell ID.

Optionally, when the resource identifier in the terminal's uplink positioning reference signal configuration is the same as the uplink positioning reference signal resource 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.

In the method provided by the embodiments of this application, during the MT-SDT process triggered by the network device, the network device sends an activation command or deactivation command of the uplink positioning reference signal to the terminal. It can realize that there is no need to wait for the terminal to trigger SDT, and the activation command or deactivation command can be flexibly sent to the terminal based on SDT on demand. And, sending an activation command or deactivation command of the uplink positioning reference signal to the terminal through a paging message. It is possible to send activation commands or deactivation commands to the terminal on demand to avoid sending activation commands to the terminal before starting uplink positioning, thus preventing the terminal from sending uplink positioning reference signals before starting uplink positioning, thereby reducing terminal power consumption. And, sending an activation command or deactivation command of the uplink positioning reference signal to the non-connected terminal through DCI. It is possible to send activation commands or deactivation commands to non-connected terminals on demand through DCI. The above solution is introduced below through three embodiments:

(1) For the situation where an activation command or deactivation command is sent to the terminal through the MT-SDT process:

Figure 9 shows a flow chart of a method for activating or deactivating an uplink positioning reference signal provided by an embodiment of the present application. This method can be applied to a system as shown in Figure 2. The method includes:

Step 902: During the MT-SDT process triggered by the network device, the network device sends an activation command or deactivation command of the uplink positioning reference signal to the terminal.

Step 904: 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.

After the network device triggers MT-SDT, the terminal will receive the message that the network device triggered MT-SDT, and then can receive the activation command or deactivation command of the uplink positioning reference signal sent by the network device to the terminal during the MT-SDT process. .

When the terminal receives the activation command, it will activate the uplink positioning reference signal configured for it. When the terminal receives the deactivation command, it will deactivate the uplink positioning reference signal configured for it.

(2) For the situation of sending activation command or deactivation command to the terminal through paging message:

Figure 10 shows a flow chart of a method for activating or deactivating an uplink positioning reference signal provided by an embodiment of the present application. This method can be applied to a system as shown in Figure 2. The method includes:

Step 1002: The network device sends a paging message to the terminal. The paging message carries an activation command or a deactivation command for the uplink positioning reference signal.

The paging message is a message used by the network device to send an activation command or a deactivation command of the uplink positioning reference signal to the terminal. Optionally, the paging message also carries at least one of the following information:

·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.

Step 1004: The terminal determines whether to activate the uplink positioning reference signal according to the paging message.

The terminal receives the activation command or deactivation command of the uplink positioning reference signal by receiving the paging message sent by the network device. When the paging message does not include the uplink positioning reference signal resource identifier and the terminal identifier, the terminal activates or deactivates the uplink positioning reference signal according to the received command.

After receiving the paging message that 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 it or whether to deactivate the uplink positioning reference signal configured for it.

Specifically, it can be divided into the following three situations:

For the situation where the paging message carries the terminal identifier:

(3) For the situation of sending activation command or deactivation command to non-connected terminal through DCI:

Figure 11 shows a flow chart of a method for activating or deactivating an uplink positioning reference signal provided by an embodiment of the present application. This method can be applied to a system as shown in Figure 2. The method includes:

Step 1102: The network device sends DCI to the terminal, and the DCI carries the activation command or deactivation command of the uplink positioning reference signal.

The terminal is in a non-connected state, which includes idle state and inactive state. The DCI is a message used by the network device to send an activation command or deactivation command of the uplink positioning reference signal to the non-connected terminal. Optionally, the DCI is at least one of the following:

·DCI format 1_0;

·DCI scrambled by P-RNTI;

·DCI scrambled by SI-RNTI.

Optionally, the DCI also carries an uplink positioning reference signal resource identifier. The uplink positioning reference signal resource identifier is used to identify the resources (time-frequency resources) 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.

Step 1104: The terminal determines whether to activate the uplink positioning reference signal according to the DCI.

The terminal receives the activation command or deactivation command of the uplink positioning reference signal by receiving the DCI sent by the network device. When the DCI does not include the uplink positioning reference signal resource identifier, the terminal activates or deactivates the uplink positioning reference signal according to the received command.

For example, if the DCI contains an activation command or a deactivation command, and the DCI contains an uplink positioning reference signal resource identifier, the terminal will compare the uplink positioning reference signal resource identifier with the resource identifier in at least one uplink positioning reference signal configuration of the terminal. . If the two are the same, the terminal will activate or deactivate the uplink positioning reference signal corresponding to the uplink positioning reference signal resource identifier (uplink positioning reference signal configuration).

It should be noted that the order of the method steps provided by the embodiments of the present application can be appropriately adjusted, the steps can also be added or deleted according to the situation, and different steps can be freely combined to form new embodiments. Any person familiar with the technical field can easily think of changing methods within the technical scope disclosed in this application, which should be covered by the protection scope of this application, and therefore will not be described again.
