[0001] This disclosure claims priority to a Chinese patent application filed with the Patent Office of China on July 18, 2023, with application number 202310885426.9 and application name “Method, device and base station for configuring a receiving terminal”, the entire contents of which are incorporated by reference into this disclosure. Technical Field

[0002] The present disclosure relates to the field of communication technologies, and in particular to a method, device, and base station for configuring a receiving terminal. Background Art

[0003] In related technologies, when there is no cellular network coverage or the positioning signal sent by the outdoor coverage base station is not enough to meet the high-precision positioning requirements (for example: the number of outdoor base station sites sending positioning reference signals is too small, the distribution of outdoor base stations is arranged in geometric correlation, the resolution of the sent positioning reference signal is not high enough, etc.), sidelink (SL) positioning is generally used. However, due to the frequent sending and receiving of SL positioning signals by a large number of terminals, the power consumption of the terminals is increased and the standby time is sharply reduced.

[0178] The following first introduces the contents involved in the solution provided by the embodiment of the present disclosure.

[0179] 1. Positioning Architecture for Next Generation Radio Access Network (NG-RAN)

[0180] As shown in Figure 1, it shows a schematic diagram of a positioning architecture applicable to NG-RAN.

[0181] In the positioning architecture shown in Figure 1, the Location Management Function (LMF) entity is responsible for selecting the positioning method and triggering the corresponding positioning measurements, and can also calculate the final positioning result and accuracy. The NG-RAN is used to send positioning reference signals or perform positioning measurements based on auxiliary information. The user equipment (UE) is used to send positioning reference signals or perform positioning measurements based on auxiliary information, and can also calculate the final positioning result and accuracy based on the measurement results. The LMF includes: the control plane called the Enhanced Serving Mobile Location Centre (E-SMLC) and the user plane called the Service Location Protocol (SLP).

[0182] 2. Positioning Process in New Radio (NR) Networks

[0183] Referring to FIG2 , the uplink positioning process may include the following steps:

[0184] Step 0: LMF sends the NR Positioning Protocol annex (NRPPa) downlink (DL) positioning reference signal (PRS) configuration information exchange (NRPPa PRS CONFIGURATION INFORMATION EXCHANGE) to the serving base station.

[0185] Step 1: The LMF sends an LTE Positioning Protocol (LPP) capability transfer to the UE to obtain the UE's positioning capability.

[0186] Step 2: The LMF sends an NRPPa POSITIONING INFORMATION REQUEST signaling to the serving gNB, requesting the UE's uplink sounding reference signal (SRS) configuration information.

[0187] Step 3: The serving gNB determines the available uplink SRS resources (gNB determines UL SRS Resources) and configures an uplink SRS resource set for the UE via step 3a. UE SRS Configuration.

[0188] Step 4: The serving gNB reports the uplink SRS configuration information to the LMF through NRPPa POSITIONING INFORMATION RESPONSE signaling.

[0189] Step 5: The serving base station gNB activates the terminal's SRS transmission (Activate UE SRS transmission).

[0190] Step 6: The LMF sends the uplink SRS configuration information to the selected gNBs through NRPPa measurement request signaling.

[0191] The SRS configuration information includes all information for uplink measurements performed by the gNB / Transmit / Receive Point (TRP).

[0192] Step 7: The LMF entity sends an LPP Provide Assistance Data message to the UE.

[0193] Step 8: The LMF entity sends LPP Request Location Information to the UE.

[0194] Step 9a: The UE performs downlink positioning reference signal measurements (DL-PRS Measurements).

[0195] Step 9b: The serving base station and the neighboring base station perform uplink positioning reference signal measurements (UL-PRS Measurements).

[0196] Step 10: The UE sends LPP Provide Location Information to the LMF entity.

[0197] Step 11: The base station sends an NRPPa measurement response (NRPPa MEASUREMENT RESPONSE) to the LMF entity.

[0198] 4. Relative Positioning Technology

[0199] Currently, positioning is mainly performed using received signal strength indicator (RSSI), time of arrival (TOA), time difference of arrival (TDOA), angle of arrival (AOA), and frequency difference of arrival (FDOA).

[0200] 5. Direct communication

[0201] As shown in Figure 3, direct communication allows nearby terminals to transmit data over a short distance via a direct communication link (SL). The wireless interface corresponding to Sidelink is called a direct communication interface, also known as a Sidelink interface or a PC5 interface.

[0202] As mentioned above, the related art does not consider scenarios where terminals can also provide positioning signals in V2X scenarios. When the positioning signals sent by outdoor base stations are insufficient to meet high-precision positioning requirements, or when there is no cellular network coverage, SL positioning is generally used. However, due to the large number of terminals frequently sending and receiving SL positioning signals, the terminal's power consumption increases and the standby time is sharply reduced. Therefore, while ensuring the efficiency of sending and receiving SL positioning signals, how to reduce the frequency of invalid transmission and measurement and reduce terminal power consumption is a technical problem that needs to be solved urgently.

[0203] Based on the above, the embodiments of the present disclosure provide a method, device and base station for configuring a receiving terminal to solve the technical problem of how to reduce the frequency of invalid transmission and measurement while ensuring the efficiency of sending and receiving SL positioning signals and reducing terminal power consumption, which is currently a technical problem that needs to be solved urgently.

[0205] Step 101: Determine a target receiving terminal and / or a transmission mode of a positioning reference signal, where the target receiving terminal is a receiving terminal of the positioning reference signal.

[0206] Optionally, the first device is one of the following: an LMF entity, any terminal participating in positioning, or a third-party terminal not participating in positioning.

[0207] Exemplarily, when the terminal participating in positioning is not on the network, the first device is any terminal participating in positioning, such as the first device is a sending terminal or a receiving terminal of a positioning reference signal; or, when the terminal participating in positioning is not on the network, the first device may also be a third-party terminal that does not participate in positioning, that is, the first device is a terminal other than a sending terminal or a receiving terminal of a positioning reference signal; wherein, the terminal being off the network means that the terminal has not established a communication connection with the network side device.

[0208] Exemplarily, when all terminals participating in positioning are on the network, the first device is the LMF entity.

[0209] Optionally, the sending mode of the positioning reference signal includes one of the following: broadcast, multicast and unicast.

[0210] Step 102: Send first information to a first terminal, where the first terminal is a terminal that sends the positioning reference signal, and the first information is used to indicate an identifier of the target receiving terminal and / or the sending mode.

[0211] In this step, by sending the identifier and / or sending mode of the target receiving terminal to the sending terminal of the positioning reference signal, the sending terminal can carry the identifier and / or sending mode of the target receiving terminal in the positioning reference signal when sending the positioning reference signal. In this way, the receiving terminal can determine whether to receive the corresponding positioning reference signal based on the identifier and / or sending mode of the target receiving terminal.

[0212] Exemplarily, the first terminal sends sidelink control information (SCI) and carries the identifier and / or transmission mode of the target receiving terminal in the SCI. In this way, when the receiving terminal detects the direct link signal, it can determine whether it is the target receiving terminal by comparing the SCI content, and receive the positioning reference signal indicated by the SCI when it is determined that it is the target receiving terminal.

[0213] Step 103: Send second information to the target receiving terminal, where the second information is used to indicate the identifier of the target receiving terminal and / or the sending mode.

[0214] For example, when the transmission mode is multicast, the first terminal transmits a positioning reference signal (PRS) with an SCI that indicates the multicast transmission mode and the identifier of the target receiving terminal. Upon receiving the SCI, the receiving terminal determines that the transmission mode is multicast and the identifier (ID) of the target receiving terminal, and compares the SCI with the ID and transmission mode configured by the first device via the second information. If the SCI matches, the receiving terminal identifies itself as the target receiving terminal and receives the PRS. If the SCI does not match, the receiving terminal does not receive the PRS.

[0215] For example, when the transmission mode is unicast, the first terminal, when transmitting a positioning reference signal, carries the multicast transmission mode indication and the identification information of the target receiving terminal in the SCI. Upon receiving the SCI, the receiving terminal determines that the transmission mode is unicast and the target receiving terminal ID, and compares the SCI with the identification ID and transmission mode configured by the first device via the second information. If the SCI matches, the receiving terminal identifies itself as the target receiving terminal and receives the positioning reference signal. If the SCI does not match, the receiving terminal does not receive the positioning reference signal.

[0216] For example, when the transmission mode is broadcast, the first terminal, when transmitting a positioning reference signal, only carries the broadcast transmission mode in the SCI, without the identifier of the target receiving terminal. Upon receiving the SCI, the receiving terminal determines that the transmission mode is broadcast and compares it with the transmission mode configured by the first device via the second information. If the SCI matches, the receiving terminal identifies itself as the target receiving terminal and receives the positioning reference signal. If the SCI does not match, the receiving terminal does not receive the positioning reference signal.

[0217] In the above embodiment, the first device determines the sending mode of the target receiving terminal and / or the positioning reference signal, and sends the sending mode of the target receiving terminal and / or the positioning reference signal to the first terminal and the target receiving terminal, so that the first terminal can carry the identifier and / or sending mode of the target receiving terminal in the positioning reference signal when sending the positioning reference signal. In this way, the receiving terminal can determine whether to receive the corresponding positioning reference signal based on the identifier and / or sending mode of the target receiving terminal, so that the terminal only receives the positioning reference signal of itself as the target receiving terminal, avoiding the terminal power consumption problem caused by a large number of terminals frequently sending and receiving positioning reference signals, and can achieve while ensuring the sending and receiving efficiency of the positioning reference signal, reducing the frequency of invalid sending and measurement and reducing terminal power consumption.

[0218] In one embodiment, in step 101, determining the target receiving terminal includes:

[0219] Acquiring candidate receiving terminal information determined by the first terminal;

[0220] The target receiving terminal is determined based on at least one of the following information:

[0221] the candidate receiving terminal;

[0222] The serving base station where the terminal participating in positioning is located;

[0223] Available terminals residing in neighboring base stations;

[0224] Terminal capabilities.

[0225] Optionally, the first terminal determines a list of candidate receiving terminals based on terminals discovered in its previous process and discovered signal measurement values.

[0226] In this embodiment, during the target receiving terminal negotiation between the first device and the first terminal, the first device performs a comprehensive analysis based on the candidate receiving terminal information determined by the first terminal, the serving base station where the terminal participating in positioning is located, the available terminals residing in the neighboring base stations, and the terminal capabilities to determine the target receiving terminal.

[0227] In one embodiment, obtaining the candidate receiving terminal information determined by the first terminal includes one of the following two methods:

[0228] Mode 1: receiving the candidate receiving terminal information sent by the first terminal;

[0229] In the first mode, the first terminal communicates directly with the first device, and the serving base station of the first terminal does not participate in the negotiation process of the receiving terminal.

[0230] Exemplarily, when the terminal is online, the first terminal determines the candidate receiving terminal information and directly sends the determined candidate receiving terminal information to the LMF entity, and the LMF entity determines the target receiving terminal and the sending mode.

[0231] Exemplarily, when the terminal is not in the network, the first terminal determines the candidate receiving terminal information and directly sends the determined candidate receiving terminal information to the service terminal (such as any terminal participating in positioning, or a third-party terminal not participating in positioning), and the service terminal determines the target receiving terminal and sending mode.

[0232] Mode 2: Receive the candidate receiving terminal information sent by the serving base station of the first terminal.

[0233] In the second mode, the serving base station of the first terminal participates in the negotiation process of the receiving terminal.

[0234] Exemplarily, when the terminal is online, the first terminal determines the candidate receiving terminal information and sends the candidate receiving terminal information to the service base station of the first terminal. The service base station of the first terminal sends the determined candidate receiving terminal information to the LMF entity, and the LMF entity determines the target receiving terminal and sending mode.

[0235] In one embodiment, in step 101, determining a transmission mode of a positioning reference signal includes:

[0236] The sending mode of the positioning reference signal is determined according to at least one of the terminal capability of the target receiving terminal, the service quality requirement of the positioning request service, the positioning service type, the positioning accuracy requirement and the positioning delay requirement.

[0237] Optionally, the transmission mode of the positioning reference signal includes unicast, multicast or broadcast.

[0238] In one embodiment, the first information is further used to indicate: a transmission resource of the positioning reference signal and a signal parameter of the positioning reference signal.

[0239] Optionally, the first device selects a transmission resource of a positioning reference signal for the first terminal from a resource pool, and determines a signal parameter of the positioning reference signal.

[0240] In this embodiment, the first device determines the transmission resources of the positioning reference signal and the signal parameters (such as waveform) of the positioning reference signal for the first terminal, and sends first information to the first terminal, indicating the identification and / or transmission mode of the target receiving terminal of the positioning reference signal, as well as the transmission resources of the positioning reference signal and the signal parameters of the positioning reference signal through the first information.

[0241] In another embodiment, the sending the first information to the first terminal includes:

[0242] The first information is sent to the first terminal through a serving base station of the first terminal; the first information is further used to indicate: a transmission resource of the positioning reference signal and a signal parameter of the positioning reference signal.

[0243] In the case where the first information is sent to the first terminal through the serving base station of the first terminal, the method further includes:

[0244] Send third information to the serving base station of the first terminal, where the third information is used to instruct the serving base station to configure transmission resources and signal parameters of the positioning reference signal.

[0245] It should be noted that the first information and the third information may be carried in one message or in different messages.

[0246] In this embodiment, the service base station of the first terminal determines the transmission resources of the positioning reference signal and the signal parameters (such as waveform) of the positioning reference signal for the first terminal, and sends first information to the first terminal through the service base station of the first terminal, indicating the identification and / or transmission mode of the target receiving terminal of the positioning reference signal, as well as the transmission resources of the positioning reference signal and the signal parameters of the positioning reference signal through the first information.

[0247] In one embodiment, the sending the second information to the target receiving terminal includes:

[0248] In case of receiving a confirmation message sent by the first terminal or the serving base station of the first terminal, the second information is sent to the target receiving terminal; wherein the confirmation message is used to indicate that the first terminal has received the first information.

[0249] In this embodiment, upon confirming that the first terminal has received the first information, the first device sends second information to the target receiving terminal, which is used to indicate the identifier of the target receiving terminal and the transmission mode of the positioning reference signal.

[0250] The following describes the method for configuring a receiving terminal in the present disclosure through specific application examples.

[0251] Application Example 1: The terminal on the network completes the negotiation configuration of the sending mode and the target receiving terminal through the LMF entity, and the serving base station communicates with the sending terminal to complete the configuration and sending of the SCI information.

[0252] Referring to Figure 5, the process mainly includes the following steps:

[0253] Step 1: The sending terminal a sends a list of candidate receiving terminals to the serving base station.

[0254] Specifically, the transmitting terminal a participating in this positioning determines a list of candidate receiving terminals based on the terminals discovered in its previous process and the measurement values ​​of the discovery signals, and sends the list of candidate terminals to the serving base station.

[0255] Step 2: The serving base station sends a list of candidate receiving terminals to the LMF entity.

[0256] Step 3: Send a message indicating the target receiving terminal list and / or the transmission mode of the positioning reference signal to the serving base station, as well as a message requesting the serving base station to configure the transmission resources and signal parameters of the positioning reference signal.

[0257] Specifically, the LMF entity determines the target receiving terminal list based on at least one of the base station where the participating positioning terminal is located, the available terminals residing in the neighboring base stations, the candidate receiving terminal list recommended by the sending terminal a, and the terminal capabilities.

[0258] Specifically, the LMF entity determines the positioning method and the sending mode of the positioning reference signal based on the terminal capabilities in the target receiving terminal list, the quality of service (QoS) requirements of the positioning request service, the positioning service type, the positioning service accuracy and delay, and other information.

[0259] Step 4: The serving base station sends the target receiving terminal list and / or the positioning reference signal transmission mode, as well as the positioning reference signal transmission resources and signal parameters to the transmitting terminal a.

[0260] Specifically, the serving base station configures the transmission resources and signal parameters of the positioning reference signal for the sending terminal a based on the configuration request of the LMF entity.

[0261] Optionally, the serving base station sends a target receiving terminal list and / or a positioning reference signal transmission mode, as well as configured positioning reference signal transmission resources and signal parameters to the sending terminal a through RRC signaling or a medium access control control element (MAC CE).

[0262] Step 5: After receiving the positive confirmation (ACK) message from the sending terminal a, the serving base station replies with a confirmation message to the LMF entity, informing the terminal that it has received the message in step 4.

[0263] Step 6: Notify the receiving terminal b of the transmission mode and target ID carried in the SL-PRS signal to be received, as well as the corresponding measurement quantity and measurement requirements.

[0264] Here, it is assumed that receiving terminal b is the target receiving terminal.

[0265] Step 7: The sending terminal a sends an SCI, which carries the sending mode and the target receiving terminal ID.

[0266] Step 8: Receiving terminal b determines that it is the target receiving terminal that expects to receive the SL-PRS based on the SCI, and performs measurement according to the measurement requirements notified by the LMF.

[0267] Specifically, when the receiving terminal b monitors the SL signal, it compares the SCI content. When it finds that the target receiving terminal identifier carried in the SCI matches its own ID and the configured sending mode, it receives the SL-PRS signal and measures the SL-PRS signal according to the measurement quantity requested by the positioning server.

[0268] Step 9: Receiving terminal b sends the measurement value to the LMF entity to complete the reception and measurement of the SL-PRS signal.

[0269] Step 10: The LMF entity completes the positioning calculation based on the measurement results.

[0270] Application example 2: The LMF entity directly configures the target receiving terminal list and sending mode for each terminal.

[0271] Referring to Figure 6, the process mainly includes the following steps:

[0272] Step 1: Send a list of candidate receiving terminals to the LMF entity.

[0273] Specifically, the transmitting terminal a participating in this positioning determines a list of candidate receiving terminals based on the terminals discovered in its previous process and the measurement values ​​of the discovery signals, and sends the list of candidate terminals to the LMF.

[0274] Step 2: The LMF entity determines the target receiving terminal list and / or transmission mode, as well as the transmission resources and signal parameters of the bit reference signal.

[0275] Specifically, the LMF entity determines the target receiving terminal list based on at least one of the base station where the participating positioning terminal is located, the available terminals residing in the neighboring base stations, the candidate receiving terminal list recommended by the sending terminal a, and the terminal capabilities.

[0276] Specifically, the LMF entity determines the positioning method and the sending mode of the positioning reference signal based on the terminal capabilities in the target receiving terminal list, the QoS requirements of the positioning request service, the positioning service type, the positioning service accuracy and delay, and other information.

[0277] Step 3: The LMF entity sends the target receiving terminal list and / or the transmission mode of the positioning reference signal, as well as the transmission resources and signal parameters of the positioning reference signal to the sending terminal a.

[0278] Step 4: Sending terminal a sends a confirmation message to the LMF entity.

[0279] The confirmation message is used to indicate that the sending terminal a has received the message in step 3.

[0280] Step 5: Notify the receiving terminal b of the transmission mode and target ID carried in the SL-PRS signal to be received, as well as the corresponding measurement quantity and measurement requirements.

[0281] Here, it is assumed that receiving terminal b is the target receiving terminal.

[0282] Step 6: The sending terminal a sends an SCI, which carries the sending mode and the target receiving terminal ID.

[0283] Step 7: Receiving terminal b determines that it is the target receiving terminal that expects to receive the SL-PRS based on the SCI, and performs measurement according to the measurement requirements notified by the LMF.

[0284] Specifically, when the receiving terminal b monitors the SL signal, it compares the SCI content. When it finds that the target receiving terminal identifier carried in the SCI matches its own ID and the configured sending mode, it receives the SL-PRS signal and measures the SL-PRS signal according to the measurement quantity requested by the positioning server.

[0285] Step 8: Receiving terminal b sends the measurement value to the LMF entity to complete the reception and measurement of the SL-PRS signal.

[0286] Step 9: LMF completes the positioning calculation based on the measurement results.

[0287] Optionally, the information exchanged between the LMF entity and the sending terminal a is carried through LPP signals or SLPP signaling.

[0288] In the above example, the LMF entity sends the transmission mode and target receiving terminal identifier to each terminal participating in positioning, completing the network's SL-PRS coordination configuration mechanism. While meeting positioning service requirements, it can also improve terminal measurement efficiency and prevent terminals that do not need to be measured from receiving positioning reference signals.

[0289] Application Example 3: When a server UE (referring to any terminal participating in positioning or a third-party terminal not participating in positioning) is offline, the target receiving terminal list and sending mode are directly configured for each terminal.

[0290] Referring to Figure 7, the process mainly includes the following steps:

[0291] Step 1: Send a list of candidate receiving terminals to the Server UE.

[0292] Specifically, the transmitting terminal a participating in this positioning determines a list of candidate receiving terminals based on the terminals discovered in its previous process and the measurement values ​​of the discovered signals, and sends the list of candidate terminals to the Server UE.

[0293] Step 2: The Server UE determines the target receiving terminal list and / or transmission mode, as well as the transmission resources and signal parameters of the bit reference signal.

[0294] Specifically, the Server UE determines the target receiving terminal list according to at least one of the base station where the participating positioning terminal is located, the available terminals residing in the neighboring base stations, the candidate receiving terminal list recommended by the sending terminal a, and the terminal capabilities.

[0295] Specifically, the Server UE determines the current positioning method and the transmission mode of the current positioning reference signal according to the terminal capabilities in the target receiving terminal list, the QoS requirements of the positioning request service, the positioning service type, the positioning service accuracy and delay, and other information.

[0296] Step 3: The Server UE sends the target receiving terminal list and / or the positioning reference signal transmission mode, as well as the positioning reference signal transmission resources and signal parameters to the transmitting terminal a.

[0297] Step 4: The sending terminal a sends a confirmation message to the Server UE.

[0298] The confirmation message is used to indicate that the sending terminal a has received the message in step 3.

[0299] Step 5: Notify the receiving terminal b of the transmission mode and target ID carried in the SL-PRS signal to be received, as well as the corresponding measurement quantity and measurement requirements.

[0300] Here, it is assumed that receiving terminal b is the target receiving terminal.

[0301] Step 6: The sending terminal a sends an SCI, which carries the sending mode and the target receiving terminal ID.

[0302] Step 7: Receiving terminal b determines that it is the target receiving terminal that expects to receive the SL-PRS according to the SCI, and performs measurement according to the measurement requirements notified by the Server UE.

[0303] Specifically, when the receiving terminal b monitors the SL signal, it compares the SCI content. When it finds that the target receiving terminal identifier carried in the SCI matches its own ID and the configured sending mode, it receives the SL-PRS signal and measures the SL-PRS signal according to the measurement quantity requested by the positioning server.

[0304] Step 8: The receiving terminal b sends the measurement value to the Server UE, completing the reception and measurement of the SL-PRS signal.

[0305] Step 9: The Server UE completes the positioning calculation based on the measurement results.

[0306] Optionally, the information exchanged between the Server UE and the sending terminal a is carried through an LPP signal or a Straight Link Positioning Protocol (SLPP) signaling.

[0307] In the above example, the Server UE sends the transmission mode and target receiving terminal identifier to each terminal participating in positioning, completing the network's SL-PRS coordinated configuration mechanism. While meeting positioning service requirements, it can also improve terminal measurement efficiency and prevent terminals that do not need to be measured from receiving positioning reference signals.

[0308] In the above scheme, when the terminal is off-network, any UE or third-party UE participating in positioning negotiates with all participating terminals to determine the target receiving terminal and the transmission mode of the positioning reference signal in this positioning. The negotiated target receiving terminal identifier and transmission mode are sent to the transmitting and receiving terminals, completing the negotiation mechanism. When all terminals are on-network, the LMF negotiates with all participating terminals to determine the target receiving terminal and the transmission mode of the positioning reference signal in this positioning. The negotiated target receiving terminal identifier and transmission mode are sent to the transmitting and receiving terminals, completing the negotiation mechanism.

[0309] After the negotiation is completed, when sending the SL-PRS signal, the sending terminal carries the identifier of the target receiving terminal and the sending mode through the SCI, so that when the receiving terminal monitors the SL signal, it can determine whether it has received the SL-PRS signal by receiving and decoding the SCI information. In this way, the terminal can only measure the positioning signal of itself as the target receiving terminal, greatly improving the measurement efficiency of the positioning signal and reducing the power consumption of the terminal.

[0310] As can be seen from the above, in the embodiment of the present disclosure, when all terminals are on the network, the transmission and reception of SL-PRS are coordinated through LMF configuration to improve the transmission and reception efficiency of SL-PRS; when all terminals are off the network, the transmission and reception of SL-PRS are configured through coordination between the terminals to improve the transmission and reception efficiency of SL-PRS, ultimately achieving the effect of reducing terminal power consumption and improving terminal standby time.

[0311] 8 , an embodiment of the present disclosure provides a method for configuring a receiving terminal, which is applied to a first terminal, where the first terminal is a terminal that transmits a positioning reference signal. Specifically, the method may include the following steps:

[0312] Step 201: Receive first information sent by a first device, where the first information is used to indicate a transmission mode of a positioning reference signal and / or an identifier of a target receiving terminal, where the target receiving terminal is a receiving terminal of the positioning reference signal.

[0313] Optionally, the first device is one of the following: a location management function LMF entity, any terminal participating in positioning, or a third-party terminal not participating in positioning.

[0314] In this embodiment, by receiving the identifier and / or transmission mode of the target receiving terminal sent by the first device, the transmitting terminal can include the identifier and / or transmission mode of the target receiving terminal in the positioning reference signal when transmitting the positioning reference signal. In this way, the receiving terminal can determine whether it is the target receiving terminal based on the identifier and / or transmission mode of the target receiving terminal and, upon confirming that it is the target receiving terminal, receive the corresponding positioning reference signal. This allows the terminal to only receive positioning reference signals for which it is the target receiving terminal, avoiding terminal power consumption issues caused by frequent transmission and reception of positioning reference signals by a large number of terminals. This ensures the transmission and reception efficiency of positioning reference signals while reducing the frequency of invalid transmissions and measurements, thereby reducing terminal power consumption.

[0315] In one embodiment, after receiving the first information sent by the first device, the method further includes:

[0316] The positioning reference signal is sent according to the first information.

[0317] For example, when the first information indicates that the transmission mode is multicast, the first terminal transmits a positioning reference signal (PRS) with the SCI, which carries the multicast transmission mode indication and the identification information of the target receiving terminal. Upon receiving the SCI, the receiving terminal determines that the transmission mode is multicast and the target receiving terminal ID, and compares the SCI with the identification ID and transmission mode configured by the first device via the second information. If the SCI matches, the receiving terminal identifies itself as the target receiving terminal and receives the PRS. If the SCI does not match, the receiving terminal does not receive the PRS.

[0318] For example, when the first information indicates a unicast transmission mode, the first terminal, when transmitting a positioning reference signal, carries the multicast transmission mode indication and the identification information of the target receiving terminal via the SCI. Upon receiving the SCI, the receiving terminal determines that the transmission mode is unicast and the target receiving terminal ID, and compares these with the identification ID and transmission mode configured by the first device via the second information. If they match, the receiving terminal identifies itself as the target receiving terminal and receives the positioning reference signal. If they do not match, the receiving terminal does not receive the positioning reference signal.

[0319] For example, when the first information indicates a broadcast transmission mode, the first terminal, when transmitting a positioning reference signal, only carries the broadcast transmission mode in the SCI, without the identifier of the target receiving terminal. Upon receiving the SCI, the receiving terminal determines that the transmission mode is broadcast and compares it with the transmission mode configured by the first device via the second information. If the SCI matches, the receiving terminal identifies itself as the target receiving terminal and receives the positioning reference signal. If the SCI does not match, the receiving terminal does not receive the positioning reference signal.

[0320] In one embodiment, before receiving the first information sent by the first device, the method further includes:

[0321] Send candidate receiving terminal information to the first device.

[0322] Optionally, the first terminal determines a list of candidate receiving terminals based on terminals discovered in its previous process and discovered signal measurement values.

[0323] Exemplarily, when the terminal is online, the first terminal determines candidate receiving terminal information and directly sends the determined candidate receiving terminal information to the LMF entity.

[0324] Exemplarily, when the terminal is not in the network, the first terminal determines candidate receiving terminal information and directly sends the determined candidate receiving terminal information to the service terminal (such as any terminal participating in positioning, or a third-party terminal not participating in positioning).

[0325] In this embodiment, the first terminal communicates directly with the first device, and the serving base station of the first terminal does not participate in the negotiation process.

[0326] In one embodiment, the sending the candidate receiving terminal information to the first device includes:

[0327] The candidate receiving terminal information is sent to the first device through the serving base station.

[0328] Exemplarily, when the terminal is online, the first terminal determines the candidate receiving terminal information and sends the candidate receiving terminal information to the service base station of the first terminal, and sends the determined candidate receiving terminal information to the LMF entity through the service base station of the first terminal.

[0329] In this embodiment, the serving base station of the first terminal participates in the negotiation process of the receiving terminal.

[0330] In one embodiment, after receiving the first information sent by the first device, the method further includes:

[0331] sending a confirmation message to a serving base station of the first terminal, where the confirmation message is used to indicate that the first terminal has received the first information; or,

[0332] Send the confirmation message to the first device.

[0333] In this embodiment, in one implementation, the serving base station participates in the negotiation process of the receiving terminal, and the first terminal sends a confirmation message to the serving base station, so that the serving base station sends a confirmation message to the first device through the serving base station to indicate that the first terminal has received the first information; in another implementation, the serving base station does not participate in the negotiation process of the receiving terminal, and the first terminal directly sends a confirmation message to the first device to indicate that the first terminal has received the first information.

[0334] In one embodiment, the first information is further used to indicate: a transmission resource of the positioning reference signal and a signal parameter of the positioning reference signal.

[0335] In one implementation, the transmission resource of the positioning reference signal and the signal parameter of the positioning reference signal are determined by the first device.

[0336] In another implementation manner, the transmission resource of the positioning reference signal and the signal parameters of the positioning reference signal are configured by a serving base station of the first terminal.

[0337] 9 , an embodiment of the present disclosure provides a method for configuring a receiving terminal, which is applied to a target receiving terminal and includes:

[0338] Step 301: Receive second information sent by a first device, where the second information is used to indicate a positioning reference signal transmission mode and an identifier of a target receiving terminal;

[0339] Optionally, the first device is one of the following: a location management function LMF entity, any terminal participating in positioning, or a third-party terminal not participating in positioning.

[0340] Step 302: Confirm whether the positioning reference signal is received according to the second information.

[0341] For example, when the transmission mode is multicast, the first terminal transmits a positioning reference signal (PRS) with an SCI indicating the multicast transmission mode and the identification information of the target receiving terminal. Upon receiving the SCI, the receiving terminal determines that the transmission mode is multicast and the target receiving terminal ID, and compares the SCI with the identification ID and transmission mode configured by the first device via the second information. If the SCI matches, the receiving terminal identifies itself as the target receiving terminal and receives the PRS. If the SCI does not match, the receiving terminal does not receive the PRS.

[0342] For example, when the transmission mode is unicast, the first terminal, when transmitting a positioning reference signal, carries the multicast transmission mode indication and the identification information of the target receiving terminal in the SCI. Upon receiving the SCI, the receiving terminal determines that the transmission mode is unicast and the target receiving terminal ID, and compares the SCI with the identification ID and transmission mode configured by the first device via the second information. If the SCI matches, the receiving terminal identifies itself as the target receiving terminal and receives the positioning reference signal. If the SCI does not match, the receiving terminal does not receive the positioning reference signal.

[0343] For example, when the transmission mode is broadcast, the first terminal, when transmitting a positioning reference signal, only carries the broadcast transmission mode in the SCI, without the identifier of the target receiving terminal. Upon receiving the SCI, the receiving terminal determines that the transmission mode is broadcast and compares it with the transmission mode configured by the first device via the second information. If the SCI matches, the receiving terminal identifies itself as the target receiving terminal and receives the positioning reference signal. If the SCI does not match, the receiving terminal does not receive the positioning reference signal.

[0344] In the above embodiment, the first device determines the sending mode of the target receiving terminal and / or the positioning reference signal, and sends the sending mode of the target receiving terminal and / or the positioning reference signal to the target receiving terminal. In this way, the receiving terminal can determine whether to receive the corresponding positioning reference signal based on the identification and sending mode of the target receiving terminal, so that the terminal only receives the positioning reference signal of itself as the target receiving terminal, avoiding the terminal power consumption problem caused by a large number of terminals frequently sending and receiving positioning reference signals, and can achieve while ensuring the sending and receiving efficiency of the positioning reference signal, reducing the frequency of invalid transmission and measurement and reducing terminal power consumption.

[0345] 10 , an embodiment of the present disclosure provides a method for configuring a receiving terminal, which is applied to a serving base station of a first terminal, including:

[0346] Step 401: Receive first information sent by a first device, where the first information is used to indicate a transmission mode of a positioning reference signal and / or an identifier of a target receiving terminal; the target receiving terminal is a receiving terminal of the positioning reference signal.

[0347] Optionally, the first device is one of the following: a location management function LMF entity, any terminal participating in positioning, or a third-party terminal not participating in positioning.

[0348] Step 402: Send the first information to a first terminal, where the first terminal is a terminal that sends the positioning reference signal.

[0349] In this embodiment, the serving base station of the first terminal participates in the negotiation process of the receiving terminal, is responsible for receiving the sending mode of the positioning reference signal and / or the identifier of the target receiving terminal sent by the first device, and sends the sending mode of the positioning reference signal and / or the identifier of the target receiving terminal to the first terminal.

[0350] In one embodiment, the first information is further used to indicate: a transmission resource of the positioning reference signal and a signal parameter of the positioning reference signal.

[0351] In this embodiment, when the serving base station sends the first information to the first terminal, the first information is further used to indicate: a transmission resource of the positioning reference signal and a signal parameter of the positioning reference signal.

[0352] In one embodiment, before sending the first information to the first terminal, the method further includes:

[0353] receiving third information sent by the first device, where the third information is used to instruct the serving base station to configure transmission resources and signal parameters of the positioning reference signal;
