Description

[0002] In the prior art, when there is no cellular network coverage or the positioning signal sent by the outdoor coverage base station is not sufficient to meet the high-precision positioning requirements (for example: the number of outdoor base station sites sending positioning reference signals is too small, the outdoor base stations are arranged in a geometric correlation, the resolution of the sent positioning reference signal is not high enough, etc.), sidelink (SL) positioning is generally used. However, since a large number of terminals frequently send and receive SL positioning signals, the power consumption of the terminals increases and the standby time is sharply reduced.

Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0171] In the embodiments of the present application, the term "and / or" describes the association relationship of the associated objects, indicating that three relationships may exist. For example, A and / or B may represent: A exists alone, A and B exist at the same time, and B exists alone. The character " / " generally indicates that the associated objects before and after are in an "or" relationship.

[0172] In the embodiments of the present application, the term "plurality" refers to two or more than two, and other quantifiers are similar.

[0173] The terminal device involved in the embodiment of the present application may be a device that provides voice and / or data connectivity to a user, a handheld device with a wireless connection function, or other processing devices connected to a wireless modem.

[0176] The following first introduces the contents involved in the solution provided in the embodiment of the present application.

[0177] 1. Positioning architecture for NG-RAN

[0178] like Figure 1 As shown, it shows a schematic diagram of a positioning architecture suitable for NG-RAN.

[0179] In such Figure 1 In the positioning architecture shown, the Location Management Function (LMF) entity is responsible for selecting the positioning method and triggering the corresponding positioning measurement, and can calculate the final positioning result and accuracy; the NG Radio Access Network (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. Among them, the LMF includes: the control plane is called the Enhanced Serving Mobile Location Centre (E-SMLC) and the user plane is called the Service Location Protocol (SLP).

[0180] 2. Positioning process in NR network

[0181] See also Figure 2 , the uplink positioning process may include the following steps:

[0182] Step 0: LMF sends NRPPa downlink positioning reference signal configuration information exchange (NRPPa DLPRS CONFIGURATION INFORMATION EXCHANGE) to the serving base station.

[0183] Step 1: LMF sends LPP capability transfer to UE to obtain the UE's positioning capability.

[0184] Step 2: LMF sends NRPPa POSITIONING INFORMATION REQUEST signaling to the serving gNB, requesting the UE's uplink SRS configuration information.

[0185] Step 3: The serving base station gNB determines the available uplink SRS resource allocation (gNB determines UL SRSResources) and configures an uplink SRS resource set for the UE through step 3a.UE SRS configuration.

[0186] Step 4: The serving gNB reports the uplink SRS configuration information to the LMF through NRPPa POSITIONING INFORMATIONRESPONSE signaling.

[0187] Step 5: The serving base station gNB activates the terminal's SRS transmission (Activate UE SRS transmission).

[0188] Step 6: LMF sends uplink SRS configuration information to the selected multiple gNBs through NRPPa MEASUREMENT REQUEST signaling.

[0189] Among them, the SRS configuration information includes all information for gNB / TRP to perform uplink measurements.

[0190] Step 7: The LMF entity sends an LPP Provide Assistance Data message to the UE.

[0191] Step 8: The LMF entity sends LPP request location information (LPP Request Location Information) to the UE.

[0192] Step 9a: The UE performs downlink positioning reference signal measurements (DL-PRS Measurements).

[0193] Step 9b: The serving base station and the neighboring base station perform uplink positioning reference signal measurements (UL-PRSMeasurements).

[0194] Step 10: The UE sends LPP Provide Location Information to the LMF entity.

[0195] Step 11: The base station sends an NRPPa measurement response (NRPPa MEASUREMENT RESPONSE) to the LMF entity.

[0196] It should be noted that LPP refers to the positioning protocol, and its full name is: LTE Positioning Protocol, LPP. NRPPa refers to the NR positioning protocol copy, and its full name is: NR Positioning Protocol annex.

[0197] IV. Existing relative positioning technology

[0198] Currently, the main positioning methods are received signal strength indicator (RSSI), time of arrival (TOA), time difference of arrival (TDOA), angle of arrival (AOA) and frequency difference of arrival (FDOA).

[0199] 5. Direct communication

[0200] like Figure 3 In the context of direct communication, adjacent terminals can transmit data via a direct communication link (Sidelink, SL) within a short distance. The wireless interface corresponding to Sidelink is called a direct communication interface, also known as a Sidelink interface or a PC5 interface.

[0201] As mentioned above, the existing technology has never considered the scenario where the terminal can also provide positioning signals in the V2X scenario. When the positioning signals sent by the outdoor coverage base station are not enough to meet the high-precision positioning requirements, or when there is no cellular network coverage, 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 terminal will increase and the standby time will be sharply reduced. Therefore, while ensuring the sending and receiving efficiency of SL positioning signals, how to reduce the frequency of invalid sending and measurement and reduce the power consumption of terminals is a technical problem that needs to be solved urgently.

[0202] Based on the above, the embodiments of the present application provide a method, device and base station for configuring a receiving terminal to solve the problem of how to reduce the frequency of invalid transmission and measurement while ensuring the efficiency of sending and receiving SL positioning signals. Reducing terminal power consumption is a technical problem that needs to be solved urgently.

[0203] See also Figure 4The embodiment of the present application provides a method for configuring a receiving terminal, which is applied to a first device and specifically includes the following steps:

[0204] Step 101: Determine a target receiving terminal and / or a transmission mode of a positioning reference signal, wherein the target receiving terminal is a receiving terminal of the positioning reference signal.

[0205] Optionally, the first device is one of the following: a location management function LMF entity, any terminal participating in positioning, and a third-party terminal not participating in positioning.

[0206] 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 a network side device.

[0207] Exemplarily, when all terminals participating in positioning are on the network, the first device is a location management function (LMF) entity.

[0208] Optionally, the sending mode of the positioning reference signal includes one of the following: broadcast, multicast and unicast.

[0209] 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.

[0210] 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.

[0211] Exemplarily, the first terminal sends direct link 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 determines that it is the target receiving terminal.

[0212] 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.

[0213] Exemplarily, when the transmission mode is multicast, when the first terminal sends a positioning reference signal, the SCI carries the indication information that the transmission mode is multicast and the identification information of the target receiving terminal. In this way, after receiving the SCI, the receiving terminal determines that the transmission mode is multicast and the target receiving terminal ID, and compares it with the identification ID and the transmission mode configured by the first device through the second information. If they are consistent, it confirms that it is the target receiving terminal and receives the positioning reference signal; if they are inconsistent, it does not receive the positioning reference signal.

[0214] Exemplarily, when the transmission mode is unicast, the first terminal carries the indication information that the transmission mode is multicast and the identification information of the target receiving terminal through the SCI when sending the positioning reference signal. In this way, when the receiving terminal receives the SCI, it determines that the transmission mode is unicast and the target receiving terminal ID, and compares it with the identification ID and the transmission mode configured by the first device through the second information. If they are consistent, it confirms that it is the target receiving terminal and receives the positioning reference signal; if they are inconsistent, it does not receive the positioning reference signal.

[0215] Exemplarily, when the transmission mode is broadcast, when the first terminal sends a positioning reference signal, it only carries the transmission mode of broadcast in the SCI, and does not carry the identifier of the target receiving terminal. In this way, when the receiving terminal receives the SCI, it determines that the transmission mode is broadcast, and compares it with the transmission mode configured by the first device through the second information. If they are consistent, it confirms that it is the target receiving terminal and receives the positioning reference signal; if they are inconsistent, it does not receive the positioning reference signal.

[0216] 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 identification 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 according to the identification 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, avoids 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.

[0217] In one embodiment, in the above step 101, determining the target receiving terminal includes:

[0218] Acquire information of candidate receiving terminals determined by the first terminal;

[0219] The target receiving terminal is determined according to at least one of the following information:

[0220] the candidate receiving terminal;

[0221] The serving base station where the terminal participating in positioning is located;

[0222] Available terminals residing in neighboring base stations;

[0223] Terminal capabilities.

[0224] Optionally, the first terminal determines a list of candidate receiving terminals according to terminals discovered in its previous process and discovered signal measurement values.

[0225] In this embodiment, during the process of the first device and the first terminal negotiating the target receiving 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 the positioning is located, and the available terminals and terminal capabilities residing in the neighboring base stations to determine the target receiving terminal.

[0226] In one embodiment, obtaining the candidate receiving terminal information determined by the first terminal includes one of the following two methods:

[0227] Mode 1: receiving the candidate receiving terminal information sent by the first terminal;

[0228] 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.

[0229] 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, and the LMF entity determines the target receiving terminal and the sending mode.

[0230] Exemplarily, when the terminal is not online, 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), and the service terminal determines the target receiving terminal and the sending mode.

[0231] Mode 2: receiving the candidate receiving terminal information sent by the serving base station of the first terminal.

[0232] In the method 2, the serving base station of the first terminal participates in the negotiation process of the receiving terminal.

[0233] Exemplarily, when the terminal is online, the first terminal determines 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 the sending mode.

[0234] In one embodiment, in the above step 101, determining the transmission mode of the positioning reference signal includes:

[0235] 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.

[0236] Optionally, the sending mode of the positioning reference signal includes unicast, multicast or broadcast.

[0237] 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.

[0238] 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.

[0239] 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.

[0240] In another embodiment, sending the first information to the first terminal includes:

[0241] The first information is sent to the first terminal through a serving base station of the first terminal; the first information is also used to indicate: a transmission resource of the positioning reference signal and a signal parameter of the positioning reference signal.

[0242] Wherein, in a case where the first information is sent to the first terminal through a serving base station of the first terminal, the method further includes:

[0243] Send third information to a 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.

[0244] It should be noted that the first information and the third information may be carried in one message or in different messages.

[0245] 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.

[0246] In one embodiment, the sending the second information to the target receiving terminal includes:

[0247] In case of receiving a confirmation message sent by the first terminal or a serving base station of the first terminal, sending the second information to the target receiving terminal; wherein the confirmation message is used to indicate that the first terminal has received the first information.

[0248] In this embodiment, when 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 sending mode of the positioning reference signal.

[0249] The following is an introduction to the method for configuring a receiving terminal in the present application through a specific application example.

[0250] Application example 1: The terminal on the network completes the negotiation configuration of the sending mode and the target receiving terminal through the location management function LMF entity, and the service base station communicates with the sending terminal to complete the configuration and sending of the SCI information.

[0251] See also Figure 5 , mainly including the following steps:

[0252] Step 1: The sending terminal a sends a list of candidate receiving terminals to the serving base station.

[0253] Specifically, the transmitting terminal a participating in this positioning determines a list of candidate receiving terminals according to the terminals discovered in its previous process and the measurement values ​​of the discovered signals, and sends the list of candidate terminals to the serving base station.

[0254] Step 2: The serving base station sends a list of candidate receiving terminals to the LMF entity.

[0255] Step 3: Send to the serving base station an indication of the target receiving terminal list and / or the transmission mode of the positioning reference signal, as well as a signal parameter and a transmission resource for requesting the serving base station to configure the positioning reference signal.

[0256] 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.

[0257] Specifically, the LMF entity determines the current positioning method and the sending mode of the current 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 latency, and other information.

[0258] Step 4: The serving base station sends a target receiving terminal list and / or a positioning reference signal transmission mode, as well as a positioning reference signal transmission resource and signal parameters to the transmitting terminal a.

[0259] 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.

[0260] Optionally, the serving base station sends a target receiving terminal list and / or a positioning reference signal transmission mode, and configured positioning reference signal transmission resources and signal parameters to the transmitting terminal a through RRC signaling or MAC CE.

[0261] Step 5: After receiving the ACK message from terminal a, the serving base station replies a confirmation message to the LMF entity, informing the terminal that it has received the message in step 4.

[0262] 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.

[0263] Here, it is assumed that receiving terminal b is the target receiving terminal.

[0264] Step 7: The sending terminal a sends SCI, which carries the sending mode and the target receiving terminal ID.

[0265] Step 8: 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 LMF.

[0266] Specifically, when monitoring the SL signal, the receiving terminal b compares the SCI content. When it is found 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.

[0267] Step 9: The receiving terminal b sends the measurement value to the LMF entity to complete the reception and measurement of the SL-PRS signal.

[0268] Step 10: The LMF entity completes the positioning calculation based on the measurement results.

[0269] Application example 2: The LMF entity directly configures the target receiving terminal list and sending mode for each terminal.

[0270] See also Figure 6 , mainly including the following steps:

[0271] Step 1: Send a list of candidate receiving terminals to the LMF entity.

[0272] Specifically, the transmitting terminal a participating in this positioning determines a list of candidate receiving terminals according to the terminals discovered in its previous process and the measurement values ​​of the discovered signals, and sends the list of candidate terminals to the LMF.

[0273] 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.

[0274] 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.

[0275] Specifically, the LMF entity determines the current positioning method and the sending mode of the current 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 latency, and other information.

[0276] Step 3: The LMF entity sends the target receiving terminal list and / or the sending 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.

[0277] Step 4: Sending terminal a sends a confirmation message to the LMF entity.

[0278] The confirmation message is used to indicate that the sending terminal a has received the message in step 3.

[0279] 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.

[0280] Here, it is assumed that receiving terminal b is the target receiving terminal.

[0281] Step 6: The sending terminal a sends SCI, which carries the sending mode and the target receiving terminal ID.

[0282] 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 LMF.

[0283] Specifically, when monitoring the SL signal, the receiving terminal b compares the SCI content. When it is found 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.

[0284] Step 8: The receiving terminal b sends the measurement value to the LMF entity to complete the reception and measurement of the SL-PRS signal.

[0285] Step 9: LMF completes the positioning calculation based on the measurement results.

[0286] Optionally, the information exchanged between the LMF entity and the sending terminal a is carried via LPP signals or SLPP signaling.

[0287] In the above example, the LMF entity sends the transmission mode and the target receiving terminal identifier to each terminal participating in positioning, completing the network's SL-PRS coordination configuration mechanism. While meeting the positioning service requirements, it can improve the terminal measurement efficiency and avoid terminals that do not need to be measured from receiving positioning reference signals.

[0288] Application example three: When the Server UE (referring to any terminal participating in positioning or a third-party terminal not participating in positioning) is offline, it directly configures the target receiving terminal list and sending mode for each terminal.

[0289] See also Figure 7 , mainly including the following steps:

[0290] Step 1: Send a list of candidate receiving terminals to the Server UE.

[0291] Specifically, the transmitting terminal a participating in the current positioning determines a list of candidate receiving terminals according to 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.

[0292] Step 2: The Server UE determines a target receiving terminal list and / or a transmission mode, as well as transmission resources and signal parameters of a bit reference signal.

[0293] 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.

[0294] Specifically, the Server UE determines the current positioning method and the sending mode of the current positioning reference signal according to 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.

[0295] Step 3: The Server UE sends a target receiving terminal list and / or a positioning reference signal transmission mode, as well as a positioning reference signal transmission resource and signal parameters to the transmitting terminal a.

[0296] Step 4: The sending terminal a sends a confirmation message to the Server UE.

[0297] The confirmation message is used to indicate that the sending terminal a has received the message in step 3.

[0298] 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.

[0299] Here, it is assumed that receiving terminal b is the target receiving terminal.

[0300] Step 6: The sending terminal a sends SCI, which carries the sending mode and the target receiving terminal ID.

[0301] Step 7: The 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.

[0302] Specifically, when monitoring the SL signal, the receiving terminal b compares the SCI content. When it is found 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.

[0303] Step 8: The receiving terminal b sends the measurement value to the Server UE to complete the reception and measurement of the SL-PRS signal.

[0304] Step 9: The Server UE completes the current positioning calculation based on the measurement results.

[0305] Optionally, the information exchanged between the Server UE and the sending terminal a is carried through an LPP signal or SLPP signaling.

[0306] In the above example, the Server UE sends the transmission mode and the target receiving terminal identifier to each terminal participating in positioning, completing the network's SL-PRS coordination configuration mechanism. While meeting the positioning service requirements, it can improve the terminal measurement efficiency and prevent terminals that do not need to be measured from receiving positioning reference signals.

[0307] In the above scheme, when the terminal is not in the network, through any UE or third-party UE participating in the positioning, it negotiates with each terminal participating in the positioning to determine the target receiving terminal and the sending mode of the positioning reference signal in this positioning, and sends the identification and sending mode of the target receiving terminal confirmed by the negotiation to the sending terminal and the receiving terminal to complete the negotiation mechanism. When all terminals are in the network, the LMF negotiates with each terminal participating in the positioning to determine the target receiving terminal and the sending mode of the positioning reference signal in this positioning, and sends the identification and sending mode of the target receiving terminal confirmed by the negotiation to the sending terminal and the receiving terminal to complete the negotiation mechanism.

[0308] After the negotiation is completed, the sending terminal carries the identification of the target receiving terminal and the sending mode through the SCI when sending the SL-PRS signal, so that the receiving terminal can determine whether it has received the SL-PRS signal by receiving and decoding the SCI information when monitoring the SL signal. In this way, the terminal can only measure the positioning signal of itself as the target receiving terminal, which greatly improves the measurement efficiency of the positioning signal and reduces the power consumption of the terminal.

[0309] From the above, it can be seen that in the embodiment of the present application, when all terminals are on the network, the sending and receiving of SL-PRS are coordinated through LMF configuration to improve the sending and receiving efficiency of SL-PRS; when all terminals are off the network, the sending and receiving of SL-PRS are configured through coordination between terminals to improve the sending and receiving efficiency of SL-PRS, thereby ultimately achieving the effect of reducing terminal power consumption and improving terminal standby time.

[0310] See also Figure 8 The embodiment of the present application provides a method for configuring a receiving terminal, which is applied to a first terminal, wherein the first terminal is a sending terminal of a positioning reference signal. Specifically, the method may include the following steps:

[0311] Step 201: Receive first information sent by a first device, where the first information is used to indicate a sending 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.

[0312] Optionally, the first device is one of the following: a location management function LMF entity, any terminal participating in positioning, and a third-party terminal not participating in positioning.

[0313] 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 carry the identifier and / or transmission mode of the target receiving terminal in the positioning reference signal when sending the positioning reference signal, so that the receiving terminal can determine whether it is the target receiving terminal according to the identifier and / or transmission mode of the target receiving terminal, and receive the corresponding positioning reference signal when confirming that it is the target receiving terminal. In this way, the terminal can only receive 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 reduce the frequency of invalid transmission and measurement and reduce terminal power consumption while ensuring the transmission and reception efficiency of the positioning reference signal.

[0314] In one embodiment, after receiving the first information sent by the first device, the method further includes:

[0315] The positioning reference signal is sent according to the first information.

[0316] Exemplarily, when the transmission mode indicated by the first information is multicast, when the first terminal sends a positioning reference signal, the SCI carries the indication information that the transmission mode is multicast and the identification information of the target receiving terminal. In this way, after receiving the SCI, the receiving terminal determines that the transmission mode is multicast and the target receiving terminal ID, and compares it with the identification ID and the transmission mode configured by the first device through the second information. If they are consistent, it confirms that it is the target receiving terminal and receives the positioning reference signal; if they are inconsistent, it does not receive the positioning reference signal.

[0317] Exemplarily, when the transmission mode indicated by the first information is unicast, the first terminal carries the indication information that the transmission mode is multicast and the identification information of the target receiving terminal through the SCI when sending the positioning reference signal. In this way, when the receiving terminal receives the SCI, it determines that the transmission mode is unicast and the target receiving terminal ID, and compares it with the identification ID and transmission mode configured by the first device through the second information. If they are consistent, it confirms that it is the target receiving terminal and receives the positioning reference signal; if they are inconsistent, it does not receive the positioning reference signal.

[0318] Exemplarily, when the transmission mode indicated by the first information is broadcast, when the first terminal sends a positioning reference signal, it only carries the transmission mode of broadcast in the SCI, and does not carry the identifier of the target receiving terminal. In this way, when the receiving terminal receives the SCI, it determines that the transmission mode is broadcast, and compares it with the transmission mode configured by the first device through the second information. If they are consistent, it confirms that it is the target receiving terminal and receives the positioning reference signal; if they are inconsistent, it does not receive the positioning reference signal.

[0319] In one embodiment, before receiving the first information sent by the first device, the method further includes:

[0320] Send candidate receiving terminal information to the first device.

[0321] Optionally, the first terminal determines a list of candidate receiving terminals according to terminals discovered in its previous process and discovered signal measurement values.

[0322] 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.

[0323] 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).

[0324] 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.

[0325] In one embodiment, the sending the candidate receiving terminal information to the first device includes:

[0326] The candidate receiving terminal information is sent to the first device through the serving base station.

[0327] Exemplarily, when the terminal is online, the first terminal determines 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.

[0328] In this embodiment, the serving base station of the first terminal participates in the negotiation process of the receiving terminal.

[0329] In one embodiment, after receiving the first information sent by the first device, the method further includes:

[0330] 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,

[0331] Sending the confirmation message to the first device.

[0332] In this embodiment, in one implementation, the service base station participates in the negotiation process of the receiving terminal, and the first terminal sends a confirmation message to the service base station, so that the service base station sends a confirmation message to the first device through the service base station to indicate that the first terminal has received the first information; in another implementation, the service 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.

[0333] 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.

[0334] 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.

[0335] In another implementation manner, the transmission resource of the positioning reference signal and the signal parameter of the positioning reference signal are configured by a serving base station of the first terminal.

[0336] See also Fig. 9 , an embodiment of the present application provides a method for configuring a receiving terminal, which is applied to a target receiving terminal, including:

[0337] Step 301: receiving second information sent by a first device, where the second information is used to indicate a transmission mode of a positioning reference signal and an identifier of a target receiving terminal;

[0338] Optionally, the first device is one of the following: a location management function LMF entity, any terminal participating in positioning, and a third-party terminal not participating in positioning.

[0339] Step 302: confirm whether the positioning reference signal is received according to the second information.

[0340] Exemplarily, when the transmission mode is multicast, when the first terminal sends a positioning reference signal, the SCI carries the indication information that the transmission mode is multicast and the identification information of the target receiving terminal. In this way, after receiving the SCI, the receiving terminal determines that the transmission mode is multicast and the target receiving terminal ID, and compares it with the identification ID and the transmission mode configured by the first device through the second information. If they are consistent, it confirms that it is the target receiving terminal and receives the positioning reference signal; if they are inconsistent, it does not receive the positioning reference signal.

[0341] Exemplarily, when the transmission mode is unicast, the first terminal carries the indication information that the transmission mode is multicast and the identification information of the target receiving terminal through the SCI when sending the positioning reference signal. In this way, when the receiving terminal receives the SCI, it determines that the transmission mode is unicast and the target receiving terminal ID, and compares it with the identification ID and the transmission mode configured by the first device through the second information. If they are consistent, it confirms that it is the target receiving terminal and receives the positioning reference signal; if they are inconsistent, it does not receive the positioning reference signal.

[0342] Exemplarily, when the transmission mode is broadcast, when the first terminal sends a positioning reference signal, it only carries the transmission mode of broadcast in the SCI, and does not carry the identifier of the target receiving terminal. In this way, when the receiving terminal receives the SCI, it determines that the transmission mode is broadcast, and compares it with the transmission mode configured by the first device through the second information. If they are consistent, it confirms that it is the target receiving terminal and receives the positioning reference signal; if they are inconsistent, it does not receive the positioning reference signal.

[0343] 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.

[0344] See also Fig.10 The embodiment of the present application provides a method for configuring a receiving terminal, which is applied to a serving base station of a first terminal, including:

[0345] 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.

[0346] Optionally, the first device is one of the following: a location management function LMF entity, any terminal participating in positioning, and a third-party terminal not participating in positioning.

[0347] Step 402: Send the first information to a first terminal, where the first terminal is a terminal that sends the positioning reference signal.
