A method for reporting positioning information and a communication device

Abstract

This application discloses a method and communication device for reporting location information. The method includes: a network device receiving a first message sent by a terminal, and sending a second message to a location management device. Both the first message and the second message include first location information, which includes a first measurement result obtained by the terminal from measuring a first reference signal. The first message is carried in RRC signaling, and the second message is carried in NRPPa signaling. Since the first location information exchanged between the terminal and the location management device is carried sequentially by RRC signaling and NRPPa signaling, and since the reporting period allowed by RRC signaling is shorter than that allowed by LPP signaling, while NRPPa signaling does not limit the reporting period, the reporting period for the terminal's location information can be shortened, thus broadening its applicability.

Description

Technical Field

[0001] This application relates to the field of positioning technology, and in particular to a method and communication device for reporting positioning information. Background Technology

[0002] In traditional positioning architectures such as Long Term Evolution (LTE) and New Radio (NR) Release R-16, the terminal sends its positioning measurement results to the location management function (LMF) via the LTE Positioning Protocol (LPP) signaling between the terminal and the positioning computing center. Since the minimum reporting period for LPP positioning measurement results is 250ms, this relatively long reporting period cannot meet the need for frequent location information. Summary of the Invention

[0003] This application provides a method and communication device for reporting location information, which can shorten the reporting cycle of location information and is better suited for application scenarios where the terminal location is frequently known.

[0004] Firstly, a method for reporting location information is provided. This method can be executed by a first communication device, which can be a communication equipment or a communication device capable of supporting the functions required for the method to be implemented, such as a chip system. The following description uses a network device as an example of the communication equipment. The method includes:

[0005] The network device receives a first message from the terminal. Subsequently, the network device sends a second message to the positioning management device. The first message carries Radio Resource Control (RRC) signaling, and the second message carries New Radio Positioning Protocol Annex (NRPPa) signaling. Both the first and second messages include first positioning information, which includes a first measurement result obtained by the terminal from measuring a first reference signal. That is, the first positioning information exchanged between the terminal and the positioning management device is carried sequentially via RRC signaling and NRPPa signaling. Since the allowed reporting period for RRC signaling is shorter than that for LPP signaling, and NRPPa signaling does not limit the reporting period, this solution shortens the reporting cycle of the terminal's positioning information compared to exchanging positioning information between the terminal and the positioning management device via LPP signaling. This solution can meet the needs of scenarios requiring frequent reporting of terminal location and has a wider range of applications.

[0006] In one possible implementation, before the network device receives the first message sent by the terminal, the method further includes:

[0007] The network device receives a third message from the location management device. This third message includes first indication information and / or second indication information. The first indication information instructs the network device to report first location information, and the second indication information instructs the network device to request the first location information from the terminal. This third message is carried on NRPPa signaling; that is, the third message used by the location management device and the terminal to request the first location information is an NRPPa message. This scheme can further shorten the terminal's positioning cycle.

[0008] In one possible implementation, the method further includes:

[0009] The network device sends a fourth message to the terminal, which requests the first location information. This fourth message is carried in RRC signaling.

[0010] It should be understood that when the network device is triggered by the second instruction, it sends a fourth message to the terminal, i.e., requests the first location information on demand, which better meets actual needs. Of course, the network device can also proactively request the first location information from the terminal to obtain more up-to-date information.

[0011] It should be understood that the first positioning information is a part of the information required by the positioning terminal. The first indication information can clarify which first positioning information the positioning management device needs, such as positioning information related to the positioning method, thus reducing the reporting of unnecessary positioning information.

[0012] In one possible implementation, the first indication information may include one or more of the following: a neighboring cell index list, a positioning method, a reporting method, and an information collection duration; wherein...

[0013] The neighbor cell index list includes one or more of the following indices: physical cell index, cell global index, and transmission point index;

[0014] The positioning method includes one or more of the following methods: observed time difference of arrival (OTDOA) positioning method, downlink angle of arrival (DL-AOA) positioning method, and downlink angle of departure (DL-AOD) positioning method;

[0015] Reporting methods include periodic reporting or triggered reporting;

[0016] The information collection period is a preset time length. The network device receives the measurement results reported by the terminal multiple times within the preset time length, and the measurement results are the measurement results periodically reported by the terminal within the preset time length.

[0017] Accordingly, the first positioning information may include: positioning method, measurement result, error information, and neighboring cell index list, wherein the positioning method is any one of the following methods: OTDOA positioning method, DL-AOA positioning method, and DL-AOD positioning method;

[0018] The measurement result is the measurement result corresponding to the positioning method, which includes any one of the following measurement results: reference signal received power (RSRP) value, reference signal time difference (RSTD) value, and angle of arrival value;

[0019] Error information is used to indicate the accuracy of the measurement result, and the error information includes one or more of the following: error value, error range, and error distribution type;

[0020] The neighbor cell index list includes one or more of the following indices: physical cell index, cell global index, and transmission point index.

[0021] In one possible implementation, the first positioning information includes the downlink angle of arrival of the terminal. This approach achieves downlink positioning via the angle of arrival, making it more widely applicable.

[0022] In one possible implementation, the first reference signal is either a positioning reference signal (PRS) or a channel state information reference signal (CSI-RS). Since the terminal and network equipment measure the CSI-RS, this scheme eliminates the need for a separate dedicated PRS measurement, thus eliminating the need for the base station to configure resources for the terminal to transmit the PRS, thereby further shortening the reporting cycle of positioning information.

[0023] Secondly, another method for reporting location information is provided. This method can be executed by a first communication device, which can be a communication equipment or a communication device capable of supporting the functions required for the method, such as a chip system. The following description uses a first network device as an example of the communication equipment. The method includes:

[0024] A first network device receives a first message sent by a terminal, the first message including second positioning information, the second positioning information including a second measurement result obtained by the terminal from measuring a second reference signal and a third reference signal; wherein, the first message is carried in RRC signaling;

[0025] The first network device sends a second message to the positioning management device. The second message includes third positioning information, which includes the second positioning information and a third measurement result obtained by the first network device from measuring the second reference signal and the third reference signal. The second message is carried in NRPPa signaling.

[0026] This scheme is similar to the first aspect, where the second positioning information exchanged between the terminal and the positioning management device is carried via RRC signaling, and the third positioning information is carried via NRPPa signaling, which can shorten the cycle of reporting the terminal's positioning information. The difference from the first aspect is that this scheme determines the terminal's location based on the terminal's second measurement result and the first network device's third measurement result, making it applicable to both uplink and downlink positioning schemes for the terminal.

[0027] In one possible implementation, the third positioning information also includes a fourth measurement result, which is the measurement result obtained by at least one second network device measuring the second reference signal and the third reference signal. In this scheme, at least one second network device can be considered a neighboring base station. The neighboring base station can inform the first network device of the fourth measurement result through the communication interface between the second network device and the first network device, so that the first network device sends the second measurement result, the third measurement result, and the fourth measurement result together to the positioning management device.

[0028] In one possible implementation, before the first network device receives the first message sent by the terminal, the method further includes:

[0029] The first network device receives a third message from the location management device. This third message includes third indication information and / or fourth indication information. The third indication information instructs the first network device to report third location information, and the fourth indication information instructs the first network device to request second location information from the terminal. The third message is carried on NRPPa signaling. Because the third message is carried on NRPPa signaling, this scheme can further shorten the terminal's location cycle.

[0030] In one possible implementation, the method further includes:

[0031] The first network device sends a fourth message to the terminal, which requests the second location information and is carried in RRC signaling.

[0032] It should be understood that when a network device is triggered by the fourth instruction, it sends a fourth message to the terminal, i.e., requests the second location information on demand, which better meets actual needs. Of course, a network device can also proactively request the second location information from the terminal to obtain more up-to-date information.

[0033] It should be understood that the second and third positioning information are only part of the information required by the positioning terminal. The third indication information can clarify which second and third positioning information the positioning management device needs, such as positioning information related to the positioning method. This can reduce the reporting of unnecessary positioning information.

[0034] In one possible implementation, the third indication information includes one or more of the following: a neighboring cell index list, a location method, a reporting method, and an information collection duration; wherein...

[0035] The neighbor cell index list includes one or more of the following indices: physical cell index, cell global index, and transmission point index;

[0036] Positioning methods include multi-round trip time (Multi-RTT) positioning methods;

[0037] Reporting methods include periodic reporting or triggered reporting;

[0038] The information collection period is a preset time length. The first network device receives the measurement results reported by the terminal multiple times within the preset time length. The measurement results are the measurement results periodically reported by the terminal within the preset time length.

[0039] Accordingly, the third positioning information includes: positioning method, measurement results, error information, and a neighboring cell index list; among which,

[0040] The positioning method is the Multi-RTT positioning method;

[0041] The measurement result is the measurement result corresponding to the positioning method. The measurement result includes the receiving and transmitting delay error inside the terminal, the receiving and transmitting delay error inside the first network device, and the receiving and transmitting delay error inside at least one second network device.

[0042] Error information is used to indicate the accuracy of measurement results, and the error information includes one or more of the following: error value, error range, and error distribution type;

[0043] The neighbor cell index list includes one or more of the following indices: physical cell index, cell global index, and transmission point index.

[0044] It should be understood that the second aspect of the solution can be used for uplink and downlink positioning of the terminal. Therefore, in one possible implementation, the second reference signal, as a downlink reference signal, can be a PRS or CSI-RS, and the third reference signal, as an uplink reference signal, can be a sounding reference signal (SRS).

[0045] Thirdly, a method for reporting location information is provided. This method can be executed by a second communication device, which can be a communication device or a communication device capable of supporting the functions required for the method to be implemented, such as a chip system. The following description uses the communication device as an example of a terminal. The method includes:

[0046] The terminal receives a fifth message sent by the network device. The fifth message is used to request first location information. The fifth message is carried in RRC signaling. The first location information includes a first measurement result obtained by the terminal from measuring a first reference signal.

[0047] After measuring the first reference signal, the terminal sends the first location information to the network device, which is carried in RRC signaling.

[0048] It should be understood that the terminal interacts with the positioning management device through the network device. The first positioning information exchanged between the terminal and the network device is carried in RRC signaling. Compared with carrying the first positioning information through LPP signaling, this can shorten the time taken for the terminal to exchange information with the positioning management device, and help to shorten the cycle of reporting the terminal's positioning information.

[0049] In one possible implementation, the fifth message is triggered by the sixth message, which is sent from the location management device to the network device and carries NRPPa signaling. That is, the message used by the terminal and the location management device to request the first location information is an NRPPa message, which can shorten the reporting cycle of the terminal's location information.

[0050] In one possible implementation, the first reference signal is a PRS or a CSI-RS.

[0051] Regarding the technical effects of the third aspect or various possible implementations of the third aspect, refer to the introduction of the technical effects of the first aspect, the second aspect, various possible implementations of the first aspect or various possible implementations of the second aspect.

[0052] Fourthly, a positioning method is provided, which can be executed by a third communication device. The third communication device can be a communication device or a communication device capable of supporting the functions required for the method to be implemented, such as a chip system. The following description uses the communication device as an example of a positioning management device. The method includes:

[0053] The positioning management device receives a seventh message sent by the first network device. This seventh message includes first positioning information. The positioning management device then determines the terminal's location based on this first positioning information. The first positioning information includes a first measurement result obtained by the terminal from measuring a first reference signal. This seventh message is carried on NRPPa signaling. Compared to using LPP signaling between the positioning management device and the first network device, this shortens the time required for the positioning management device to locate the terminal.

[0054] In one possible implementation, before the location management device receives the seventh message sent by the first network device, the method further includes:

[0055] The location management device sends an eighth message to the first network device. The eighth message includes a fifth indication information and / or a sixth indication information. The fifth indication information is used to instruct the first network device to report the first location information, and the sixth indication information is used to instruct the first network device to request the first location information from the terminal. The eighth message is carried in NRPPa signaling.

[0056] In one possible implementation, the first reference signal is used as a PRS or CSI-RS, adapted to the downlink positioning method.

[0057] Fifthly, a positioning method is provided, which can be executed by a third communication device. The third communication device can be a communication device or a communication device capable of supporting the functions required for the method to be implemented, such as a chip system. The following description uses a positioning management device as an example. The method includes:

[0058] The positioning management device receives a seventh message sent by the first network device. This seventh message includes second positioning information. The positioning management device then determines the terminal's location based on this second positioning information. The second positioning information includes a second measurement result obtained by the terminal from measuring a second reference signal and a third measurement result obtained by the first network device from measuring the second and third reference signals. This seventh message is carried on NRPPa signaling. This scheme can be used for both uplink and downlink positioning. Compared to positioning management devices and the first network device using LPP signaling, it can shorten the positioning management device's terminal location cycle.

[0059] In one possible implementation, before the location management device receives the seventh message sent by the first network device, the method further includes:

[0060] The location management device sends an eighth message to the first network device. The eighth message includes a seventh indication information and / or an eighth indication information. The seventh indication information is used to instruct the first network device to report the second location information, and the eighth indication information is used to instruct the first network device to request the second location information from the terminal. The eighth message is carried in NRPPa signaling.

[0061] It should be understood that in the uplink and downlink positioning methods, at least one second network device may be involved in measuring the uplink signal sent by the terminal. In possible implementations, at least one second network device may send the measurement results to a first network device, which then informs the positioning management device; or, at least one second network device may directly inform the positioning management device of the measurement results.

[0062] For example, the second positioning information may further include a fourth measurement result, which is a fourth measurement result obtained by at least one second network device measuring the second reference signal and the third reference signal respectively. That is, at least one second network device can send the measurement result to the first network device, and then the first network device can inform the positioning management device.

[0063] In this case, the method further includes: the location management device sending a measurement request message to at least one second network device, the measurement request message being carried in NRPPa signaling, the measurement request message including a neighbor cell index list to inform at least one second network device which first network device the third measurement result needs to be reported to.

[0064] For example, the method further includes:

[0065] The positioning management device receives third positioning information from at least one second network device. This third positioning information includes a fourth measurement result obtained by the at least one second network device from measuring the second reference signal and the third reference signal, respectively. In other words, at least one second network device directly informs the positioning management device of the measurement result.

[0066] In this case, the method further includes:

[0067] The location management device sends a ninth message to at least one second network device, which requests third location information corresponding to each second network device. The ninth message is carried in NRPPa signaling.

[0068] The location management device receives third location information sent by at least one second network device, which is carried in NRPPa signaling.

[0069] Regarding the technical effects of the fourth or fifth aspect, or the various possible implementations of the fourth or fifth aspect, reference can be made to the description of the technical effects of the first aspect, the second aspect, the various possible implementations of the first aspect, or the various possible implementations of the second aspect.

[0137] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the embodiments of this application will be further described in detail below with reference to the accompanying drawings.

[0138] Before introducing this application, some terms used in the embodiments of this application will be briefly explained to facilitate understanding by those skilled in the art.

[0139] 1) The terminal (also referred to as user equipment (UE)) in this application embodiment is a device with wireless transceiver capabilities. This terminal device can communicate with the core network via a radio access network (RAN) and exchange voice and / or data with the RAN. The terminal device can be deployed on land, including indoors or outdoors, handheld or vehicle-mounted; it can also be deployed on water (such as on ships); and it can be deployed in the air (e.g., on airplanes, balloons, and satellites). The terminal device can be a mobile phone, tablet computer, computer with wireless transceiver capabilities, virtual reality (VR) terminal, augmented reality (AR) terminal, wireless terminal in industrial control, wireless terminal in self-driving, wireless terminal in remote medical care, wireless terminal in smart grid, wireless terminal in transportation safety, wireless terminal in smart city, wireless terminal in smart home, etc. The terminal equipment may include, for example, user equipment (UE), wireless terminal equipment, mobile terminal equipment, device-to-device (D2D) terminal equipment, vehicle-to-everything (V2X) terminal equipment, machine-to-machine / machine-type communications (M2M / MTC) terminal equipment, internet of things (IoT) terminal equipment, subscriber unit, subscriber station, mobile station, remote station, access point (AP), remote terminal, customer premises equipment (CPE), fixed wireless access (FWA), access terminal, user terminal, user agent, or user device, etc.For example, this can include mobile phones (or "cellular" phones), computers with mobile terminal devices, portable, pocket-sized, handheld, and computer-embedded mobile devices. Examples include Personal Communication Service (PCS) phones, cordless phones, Session Initiation Protocol (SIP) phones, Wireless Local Loop (WLL) stations, and Personal Digital Assistants (PDAs). It also includes limited devices, such as those with low power consumption, limited storage capacity, or limited computing power. Examples include information sensing devices such as barcode scanners, radio frequency identification (RFID), sensors, Global Positioning System (GPS), and laser scanners.

[0140] As an example and not a limitation, in this embodiment, the terminal can also be a wearable device. Wearable devices, also known as wearable smart devices or smart wearable devices, are a general term for devices that utilize wearable technology to intelligently design and develop everyday wearables, such as glasses, gloves, watches, clothing, and shoes. Wearable devices are portable devices that are worn directly on the body or integrated into the user's clothing or accessories. Wearable devices are not merely hardware devices, but also achieve powerful functions through software support, data interaction, and cloud interaction. Broadly speaking, wearable smart devices include those that are feature-rich, large in size, and can achieve complete or partial functions without relying on a smartphone, such as smartwatches or smart glasses, as well as those that focus on a specific type of application function and require the use of other devices such as smartphones, such as various smart bracelets, smart helmets, and smart jewelry for vital sign monitoring.

[0141] The various terminals described above, if located in a vehicle (e.g., placed inside or installed inside a vehicle), can be considered as vehicle-mounted terminal devices, also known as on-board units (OBUs).

[0142] The aforementioned terminals can establish connections with the operator's network through interfaces provided by the operator's network (such as N1), and use data and / or voice services provided by the operator's network. The terminal devices can also access the DN (Network Provider) through the operator's network, and use operator services deployed on the DN, and / or services provided by third parties. These third parties can be service providers outside of the operator's network and terminal devices, and can provide other data and / or voice services to the terminal devices. The specific form of these third parties can be determined based on the actual application scenario and is not limited here.

[0143] 2) The core network involved in this application embodiment may include network devices that process and forward user signaling and data. For example, it includes AMF, session management function (SMF), user plane gateway, location management device, and other core network devices. The user plane gateway can be a server with functions such as mobility management, routing, and forwarding of user plane data, generally located on the network side, such as a serving gateway (SGW), packet data network gateway (PGW), or user plane function (UPF). AMF and SMF are equivalent to the mobility management entity (MME) in the LTE system. AMF is mainly responsible for admission aspects, and SMF is mainly responsible for session management. Of course, the core network may also include other network elements, which are not listed here.

[0144] The location management device has a location function. The location management device involved in the embodiments of this application may include a location management function (LMF) or a location management component (LMC), or it may be a local location management function (LLMF) located in a network device. The embodiments of this application are not limited to this. For ease of description, the following embodiments all use an LMF as an example for the location management device.

[0145] 3) The network devices involved in the embodiments of this application include, for example, access network (AN) devices. The NG-RAN involved in the embodiments of this application may include one or more access network devices. Access network devices in NG-RAN may also be called base stations, RAN nodes, or RAN devices; a network device in a V2X technology is a roadside unit (RSU). An RSU can be a fixed infrastructure entity supporting V2X applications and can exchange messages with other entities supporting V2X applications. A network device is a network-side entity used for transmitting and / or receiving signals. It can be used to convert received air frames to and from Internet Protocol (IP) packets, acting as a router between the terminal and the rest of the access network, where the rest of the access network may include IP networks, etc. The network device can also coordinate the attribute management of the air interface. For example, a network device may be an evolved Node B (eNB or e-NodeB) in LTE. An eNB is a device deployed in a radio access network that meets 4G standards and provides wireless communication functions for terminals. The access network equipment can also be a new radio controller (NR controller), a gNode B (gNB) in a 5G system, a centralized unit, a new wireless base station, a remote radio module, a micro base station (also known as a small cell), a relay, a distributed unit, a macro base station of various forms, a transmission reception point (TRP), a transmission measurement function (TMF), or a transmission point (TP), or any other wireless access device, or a base station in next-generation communications, but the embodiments of this application are not limited thereto.Network devices may also include radio network controllers (RNCs), Node Bs (NBs), base station controllers (BSCs), base transceiver stations (BTSs), home base stations (e.g., home-evolved Node Bs or home Node Bs (HNBs), base band units (BBUs), or wireless fidelity (Wi-Fi) access points (APs), etc.

[0146] In some deployments, base stations (such as gNBs) can consist of centralized units (CUs) and distributed units (DUs). This involves splitting the functions of the original LTE access network base stations, deploying some functions in a CU and the remaining functions in a DU. Multiple DUs share a single CU, which saves costs and facilitates network expansion. The CU and DU split can be based on the protocol stack, with the RRC, SDAP, and PDCP layers deployed in the CU, and the remaining Radio Link Control (RLC), MAC, and PHY layers deployed in the DU. CUs and DUs can connect via the F1 interface. A CU represents a gNB connected to the core network via the NG interface, while a CU represents a gNB connected to other gNBs via the Xn interface.

[0147] Furthermore, the CU can be divided into the CU-control plane (CP) and the CU-user plane (UP). The CU-CP handles control plane functions, primarily including the RRC and the corresponding PDCP (PDCP-C). PDCP-C is mainly responsible for control plane data encryption / decryption, integrity protection, and data transmission. The CU-UP handles user plane functions, primarily including the SDAP and the corresponding PDCP (PDCP-U). SDAP is mainly responsible for processing core network data and mapping flows to bearers. PDCP-U is mainly responsible for data plane encryption / decryption, integrity protection, header compression, sequence number maintenance, and data transmission. The CU-CP and CU-UP are connected via the E1 interface. The CU-CP represents the gNB connected to the core network via the NG interface. The control plane (F1-C) and DU are connected via the F1 interface. The CU-UP is connected to the user plane (F1-U) and DU via the F1 interface. Alternatively, PDCP-C may also be located within the CU-UP.

[0148] 4) Downlink angle of departure (DAOD / DL-AOD) is the direction of electromagnetic wave departure observed from the network device during downlink electromagnetic wave transmission between the network device and the terminal. It can be used to locate the terminal.

[0149] 5) Uplink Angle of Arrival (UAOA / UL-AOA) can be used for terminal location. At least two network devices involved in terminal location measurement of the SRS sent by the terminal can obtain the AOA. The location of the terminal can be determined by the intersection of the rays emitted by each network device at the corresponding AOA.

[0150] 6) Time difference of arrival (TDOA) is the transmission time difference between signals sent from a terminal to two network devices, and can be used for terminal positioning. Depending on the object being measured, it can be (downlink time difference of arrival, DL-TDOA) or (uplink time difference of arrival, UL-TDOA). In some embodiments, DL-TDOA can also be called UTDOA, and UL-TDOA can also be called observed time difference of arrival (OTDOA).

[0151] 7) The terms "system" and "network" in the embodiments of this application can be used interchangeably. The term "multiple" refers to two or more. The term "and / or" describes the relationship between related objects, indicating that there can be three relationships. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. In addition, the character " / ", unless otherwise specified, generally indicates that the related objects before and after it are in an "or" relationship.

[0152] "At least one of the following" or similar expressions refer to any combination of these items, including any combination of single or multiple items. For example, at least one of a, b, or c can mean: a, b, c, a and b, a and c, b and c, or a, b, and c, where a, b, and c can be single or multiple.

[0153] Furthermore, unless otherwise stated, the ordinal numbers such as "first" and "second" mentioned in the embodiments of this application are used to distinguish multiple objects and are not used to limit the order, timing, priority, or importance of multiple objects. For example, "first message" and "second message" are only used to distinguish different messages, and do not indicate that the two messages are different in priority, sending order, or importance.

[0154] Figure 1 A schematic diagram of the positioning architecture in LTE and NR Rel-16, as shown below. Figure 1 As shown, the network elements / modules involved mainly include three parts: next-generation radio access network (NG RAN), terminals, and core network.

[0155] The core network includes the Location Management Function (LMF), Access and Mobility Management Function (AMF), Service Location Protocol (SLP), and Evolved Serving Mobile Location Centre (E-SMLC). The location server, i.e., the Location Management Function (LMF), connects to the AMF, and the LMF and AMF are connected via the NLs interface. The LMF is responsible for supporting different types of location services for the terminal, including locating the terminal and delivering auxiliary data to the terminal. The AMF can receive location service requests related to the terminal from the 5th generation core network location services (5GC LCS) entity, or the AMF itself can initiate some location services on behalf of a specific terminal and forward the location service requests to the LMF. After receiving the location information returned by the terminal, the relevant location information is returned to the 5GC LCS entity.

[0156] NG RAN can include next-generation node B (gNB) and next-generation evolved node B (ng-eNB). gNB and ng-eNB are connected via the Xn interface, and LMF is connected to ng-eNB / gNB via the NG-C interface.

[0157] The terminal can measure downlink signals from NG RAN and other sources to support positioning. gNB / ng-eNB can provide measurement information to the terminal and convey this information to LMF.

[0158] Information exchanged between the LMF and the terminal, such as terminal capability information transmission, auxiliary information transmission, and measurement information, can be carried through LTE positioning protocol (LPP) messages. LPP messages are sent via the Uu and NG-C interfaces. On the terminal side, LPP messages are encapsulated as non-access stratum (NAS) signaling. Upon receiving the NAS signaling from the terminal (the base station is unaware that the terminal is sending an LPP message), it forwards it to the AMF. The AMF parses the NAS signaling to obtain the LPP message and then passes it to the LMF. Similarly, LPP messages sent from the LMF are encapsulated as NAS signaling and sent to the base station, which then forwards them directly to the terminal. Because LPP allows terminals to report positioning measurement results in a minimum period of 250ms, the reporting period is relatively long and not well-suited for certain scenarios, such as those requiring frequent user location information or monitoring user behavior.

[0159] Therefore, the solution provided in this application uses NRPPa messages to carry information exchanged between the LMF and the base station. Since NRPPa messages do not limit the reporting cycle of positioning measurement results, this solution can shorten the positioning cycle of the terminal, thus making it applicable to scenarios requiring frequent positioning and having a wider range of applications.

[0160] The positioning method provided in this application can be applied to various communication systems, such as Long Term Evolution (LTE) systems, 5th Generation (5G) systems (e.g., NR), and next-generation communication systems (e.g., 6G). Of course, the technical solution of this application can also be applied to other communication systems, as long as the communication system has a positioning requirement for the terminal. Furthermore, the communication system can also be applied to future-oriented communication technologies. The system described in this application is for the purpose of more clearly illustrating the technical solution of this application and does not constitute a limitation on the technical solution provided in this application. Those skilled in the art will understand that, with the evolution of network architecture, the technical solution provided in this application is equally applicable to similar technical problems.

[0161] Figure 2This paper illustrates a network architecture for a communication system applicable to embodiments of this application. The communication system includes a core network, NG-RAN, and terminals. The core network includes network elements / modules such as LMF, AMF, secure user planelocation (SUPL) location platform (SLP), and enhanced serving mobile location center (E-SMLC). The NG RAN includes network elements / modules such as gNB and ng-eNB. The specific functions of the LMF, AMF, SLP, E-SMLC, gNB, and ng-eNB, and the connection relationships between these network elements / modules, can be found above. Figure 1 The relevant details will not be repeated here.

[0162] and Figure 1 The difference is, Figure 2 In the network architecture shown, an LMC is added to NG-RAN. The LMC is deployed internally within the base station, such as in the gNB or ng-ENB. In this network architecture, the LMC functions as an internal feature of the base station, therefore no new interface needs to be introduced.

[0163] Figure 3 This application illustrates another network architecture for a communication system to which embodiments of this application are applicable, such as... Figure 3 As shown, the communication system also includes a core network, NG-RAN, and terminals. Figure 2 The difference is, Figure 3 In the network architecture shown, the LMC acts as an independent logical node in NG-RAN, connected to the base station through a new interface, for example... Figure 3 In the process, the LMC is connected to the gNB-CU via the Itf interface.

[0164] Figure 4 This application illustrates another network architecture for a communication system to which embodiments of this application are applicable, such as... Figure 4 As shown, the communication system also includes a core network, NG-RAN, and terminals. The LMC operates as an independent logical node within the NG-RAN, connected to... Figure 3 The difference is that LMC can Figure 4 The new interface allows for simultaneous connection to multiple base stations. Figure 4 Taking the LMC connected to two base stations simultaneously as an example, in actual implementation, the LMC can also be connected to more base stations.

[0165] It should be understood that the above Figure 1 , Figure 2 , Figure 3 , Figure 4This is merely an exemplary description of a communication system to which the embodiments of this application are applicable, and does not specifically limit the type, number, connection method, etc., of the network elements included in the communication system to which this application is applicable. Figures 2-4 The network elements / modules indicated by the dashed lines are not essential and are optional. For example, E-SMLC or SLP are not essential. Alternatively, the network elements / modules indicated by the dashed lines may be in another form, such as gNB or ng-eNB, which are also called TRP in some embodiments, and the terminal is called SET in some embodiments.

[0166] It should be understood that positioning methods include those mentioned above, such as OTDOA positioning, DL-AOA positioning, DL-AOD positioning, UL-AOA positioning, and Multi-RTT positioning. Generally speaking, they can be categorized into uplink positioning methods, downlink positioning methods, and uplink / downlink positioning methods. It's important to note that uplink and downlink are relative terms. If the transmission direction from the base station to the terminal is downlink (using this as an example), then the transmission direction from the terminal to the base station is uplink; conversely, if the transmission direction from the base station to the terminal is uplink, then the transmission direction from the terminal to the base station is downlink.

[0167] The positioning method provided in the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0168] Please see Figure 5 This is a flowchart of a downlink positioning method provided in an embodiment of this application. In the following description, this method will be applied to... Figures 2-4 The example shown is a communication system. Furthermore, this method can be executed by three communication devices, such as a first communication device, a second communication device, and a third communication device. For ease of explanation, the following description assumes that the method is executed by a network device, a terminal, and a location management device; that is, the first communication device is a network device, the second communication device is a terminal, and the third communication device is a location management device. It should be noted that the embodiments in this application are only illustrative of... Figures 2-4 The example given is a communication system, but it is not limited to this scenario. It should be understood that the current terminal is currently connected to one network device (which may be called a serving base station). For ease of description, this network device will be referred to as a serving base station in the following text. In the following text, the location management device is taken as an LMF network element. It should be understood that in future communications such as 6G, the location management device may still be an LMF network element, or may have other names; this application embodiment does not limit this.

[0169] Specifically, the detailed process of the positioning method provided in this application embodiment is described as follows:

[0170] S501. The terminal sends a first message to the serving base station, and the serving base station receives the first message, wherein the first message includes first location information, and the first location information is carried in RRC signaling.

[0171] In this embodiment, the serving base station can be a device in the NG RAN, such as a gNB or ng-eNB; or, the serving base station can be an LMC. As mentioned above, if the LMC functions as a feature within a base station, then the serving base station is the base station where the LMC resides. If the LMC deployment scheme is as follows... Figure 3 or Figure 4 In other words, if the LMC is an independent logical node connected to one or more base stations through an interface, then the serving base station is any base station connected to the LMC.

[0172] The first positioning information can be understood as a portion of the information required by the positioning terminal. Other positioning information needed to complete the terminal's positioning process can be found in existing technologies and will not be elaborated here. For example, the first positioning information includes part or all of the information obtained from the first measurement result after the terminal measures the first reference signal sent by the base station. It should be understood that the first reference signal is a downlink reference signal. In some embodiments, the first reference signal can be a PRS or a CSI-RS. Since the terminal and the base station measure the CSI-RS, using the CSI-RS as the first reference signal eliminates the need for separately measuring a dedicated PRS, and therefore eliminates the need for the base station to configure resources for the terminal to send the PRS, thus shortening the reporting cycle of positioning information.

[0173] In some embodiments, the information elements carried by the first measurement result (hereinafter referred to as information elements) may include one or more of RSRP values, RSTD values, and angles of arrival. For example, the first measurement result may include the RSRP values ​​corresponding to each PRS transmit beam. It should be understood that the first measurement result is used for positioning, and in other embodiments, the first measurement result may also include other possible measurement values, which will not be listed here.

[0174] In addition to the first measurement result, the first positioning information may also include other positioning information. In some embodiments, the first positioning information may also include a positioning method, such as one of the OTDOA positioning method, DL-AOA positioning method, and DL-AOD positioning method. Of course, the positioning method may also include the DL-AOA positioning method, UL-AOD positioning method, etc. The specific implementation of the positioning method is not limited in the embodiments of this application, as long as it is applicable to downlink positioning.

[0175] In other embodiments, the first positioning information may further include error information indicating the measurement result. For example, the first positioning information may include one or more of error value, error range, and error distribution type. For instance, if the first measurement result included in the first positioning information includes an RSTD value, then the error information included in the first positioning information may be RSTD quality information, that is, one or more of information such as the error value, error range, and error distribution type of the RSTD value. It should be understood that if the first measurement result included in the first positioning information includes an RSRP value, then the error information included in the first positioning information may be RSRP quality information; or, if the first measurement result included in the first positioning information includes an AOA value, then the error information included in the first positioning information may be AOA quality information.

[0176] In some other embodiments, the first location information may also include a neighboring cell index list. For example, the first location information may include one or more identifiers such as the physical cell identity (physCell Id), the transmission point identity (Trp ID) in the cellGlobal Id.

[0177] After obtaining the first positioning measurement result, the terminal can send the first positioning information, including the first positioning measurement result, to the serving base station. In some embodiments, the terminal can send the first positioning information to the serving base station via RRC signaling. Since the reporting period of RRC signaling (typically 160ms) is shorter than the reporting period of LPP signaling (typically 250ms), the use of RRC signaling for the first positioning information exchanged between the terminal and the serving base station in this embodiment helps to shorten the reporting period of the terminal's positioning information.

[0178] S502, The serving base station sends the first location information to the LMF, and the LMF receives the first location information, which is carried in NRPPa signaling.

[0179] After receiving the first location information, the serving base station sends it to the LMF so that the LMF can calculate the terminal's location based on the first location information. For example, the serving base station can send a second message to the LMF, which carries the first location information; this second message is an NRPPa message. That is, the serving base station sends the first location information to the LMF via NRPPa signaling. Since NRPPa signaling does not limit the duration of the reporting period, and the reporting period of RRC signaling (usually 160ms) is shorter than the reporting period of LPP signaling (usually 250ms), the first location information exchanged between the terminal and the LMF is carried sequentially via RRC signaling and NRPPa signaling, which shortens the reporting period of the terminal's location information, and thus shortens the reporting period of the terminal's location.

[0180] S503 and LMF determine the location of the terminal based on the first positioning information.

[0181] LMF (Local Mobility Calculation) can calculate the terminal's location based on the initial location information and other possible location information using a location calculation method. The location calculation method is explained in the principles of LMF positioning and will not be repeated here. It should be understood that other location information required for LMF positioning, i.e., location information besides the initial location information, can be found in existing technologies and will not be elaborated upon here.

[0182] LMF can collect the terminal's location information before locating the terminal. For example, please refer to [link to example]. Figure 6 This is a flowchart illustrating a positioning method provided in an embodiment of this application. Prior to S501, the method may also perform the following steps:

[0183] S601, LMF sends a third message to the serving base station, and the serving base station receives the third message. The third message includes first indication information and / or second indication information. The third message is carried in NRPPa signaling. The first indication information is used to instruct the serving base station to report the first location information, and the second indication information is used to instruct the serving base station to request the first location information from the terminal.

[0184] It should be understood that the term "third message" is merely an example of a name, and the specific name of the third message is not limited in this application embodiment. For example, the third message can also be called a location information request message. It should be noted that the third message can be a newly defined NRPPa message or an existing NRPPa message. If the third message is an existing NRPPa message, the first indication information or the second indication information can be a newly added field in the NRPPa message; or the first indication information or the second indication information can reuse a field already defined in the NRPPa message. Similarly, if the third message is an existing NRPPa message, the first indication information or the second indication information can be a newly added field in the NRPPa message; or the first indication information or the second indication information can reuse a field already defined in the NRPPa message.

[0185] As an example, the LMF can send a third message to the serving base station via NRPPa signaling to minimize the time required for terminal positioning and shorten the cycle of terminal reporting positioning information. Of course, besides being sent to the serving base station via NRPPa signaling, the third message can also be sent in other forms; this application does not impose specific limitations on the method of sending the third message. For example, the third message can be carried in RRC signaling or LPP signaling.

[0186] The first indication information is used to instruct the network device to report the terminal's first location information. The first location information reported by the network device varies depending on the information included in the first indication information. The following describes several possible types of information included in the first indication information, and their corresponding first location information.

[0187] 1) The first indication information may include a neighbor cell index list, which is used to instruct the serving base station to report the first location information related to the neighbor cell index list in order to minimize location failure.

[0188] 2) The first indication information may include a positioning method to instruct the serving base station to report first positioning information corresponding to the positioning method, so as to avoid the first positioning information reported by the serving base station being unusable for positioning calculation methods supported by LMF. For example, the positioning method may include an OTDOA positioning method, and the first positioning information may include an RSTD value used for OTDOA positioning; another example is that the positioning method includes a DL-AOD positioning method, and the first positioning information may include an RSRP value used for DL-AOD positioning, and so on. It should be understood that the first indication information may include multiple positioning methods, and the first positioning information may include one or more of these positioning methods. For example, the serving base station may select one positioning method from the multiple positioning methods indicated by the first indication information and report the first positioning information corresponding to the selected positioning method. Alternatively, the serving base station may select at least two positioning methods from the multiple positioning methods indicated by the first indication information and report the first positioning information corresponding to these at least two positioning methods. Or, the serving base station may report first positioning information corresponding to each of the multiple positioning methods indicated by the first indication information. When the serving base station reports first positioning information corresponding to multiple positioning methods, the LMF can select the first positioning information corresponding to one of the positioning methods to calculate the terminal's location; or, the LMF can also calculate the terminal's location using the first positioning information corresponding to each of the multiple positioning methods, that is, combine multiple positioning methods to achieve terminal positioning.

[0189] It should be noted that the first location information may or may not include the location method.

[0190] 3) The first indication information may include the reporting method of the first location information, such as periodic reporting or triggered reporting. Reporting the first location information based on trigger conditions can meet the real-time positioning requirements of the terminal. Periodic reporting of the first location information can achieve multiple positioning of the terminal without requiring more interactions between the LMF, the serving base station, and the terminal. It should be understood that if the reporting method included in the first indication information is periodic reporting, then the first indication information should carry the reporting period; or, the reporting period can be default, for example, the reporting period is predefined or specified by the protocol.

[0191] It should be understood that if the reporting method indicated by the first indication information is periodic reporting, then after receiving the third message, the serving base station will report the first location information to the LMF multiple times according to the reporting period; if the reporting method indicated by the first indication information is triggered reporting, then after receiving the third message, the serving base station will report the first location information to the LMF once.

[0192] Alternatively, the serving base station may proactively request first location information from the terminal. For example, if the third message includes first indication information, the serving base station can also request the first location information from the terminal. The serving base station may also proactively report the first location information to the LMF. For example, if the third message includes second indication information, after requesting the first location information from the terminal, the serving base station can proactively report the first location information to the LMF.

[0193] 4) The first indication information may include the information collection duration, which instructs the serving base station to report the terminal's first location information within that information collection duration, helping to determine the terminal's movement trajectory. It should be understood that the terminal periodically reports measurement results within the information collection duration. If the first indication information includes the information collection duration, then by default, the first indication information instructs the serving base station to periodically report the terminal's first location information.

[0194] It should be noted that, in some embodiments, the first indication information may include any combination of the above four types of information. For example, the first indication information may include a neighboring cell index list and a positioning method, or it may include a neighboring cell index list and a positioning method and a reporting method, or it may include a neighboring cell index list and a positioning method, a reporting method and an information collection duration; these will not be listed one by one here.

[0195] It should be understood that before requesting the terminal's initial location information from the serving base station, the LMF can interact with the terminal to exchange location assistance information. For example, the LMF needs to inform the terminal which cells are being measured. Since the PRS configurations of different cells are different, the LMF also needs to inform the terminal of the PRS configuration for each cell.

[0196] Specifically, S601a, LMF, and terminal interactive positioning assistance information.

[0197] The interaction between the LMF and the terminal for location assistance information is similar to the process in the OTDOA positioning process where the terminal and LMF exchange information via LPP (Local Power Proportion) information. Specifically, the LMF obtains the terminal's positioning capabilities. For example, the LMF requests positioning capabilities from the terminal through the LPP request capability process, and the terminal reports its positioning capability information to the LMF through the LPP provide capability process. This positioning capability information may include the positioning methods supported by the terminal and the measurement capabilities corresponding to those methods. The terminal requests location assistance information from the LMF, and the LMF sends assistance information to the terminal through the LPP provide assistance data process, etc., which will not be elaborated further here. Location assistance information may include the cell index of the cell the terminal needs to measure, such as the cell index of neighboring cells and / or the cell index of a reference cell, and may also include PRS (Positioning Assistance System) configuration, etc.

[0198] S602, The serving base station sends a fourth message to the terminal, and the terminal receives the fourth message. The fourth message is used to request the first location information and is carried in RRC signaling.

[0199] After receiving the third message, if the third message carries the second indication information, the serving base station may send a fourth message to the terminal. As an example, the serving base station can send the fourth message to the terminal via RRC signaling.

[0200] Similar to the third message, the fourth message may also include some indication information. For example, the fourth message may include third indication information for indicating a positioning method, and for requesting positioning information related to the positioning method indicated by the third indication information. The terminal sends first positioning information corresponding to the third indication information to the serving base station. For example, if the positioning method indicated by the third indication information is the OTDOA positioning method, the first positioning information includes RSTD values ​​and / or RSTD quality; or, for example, if the positioning method indicated by the third indication information is the DL-AOD positioning method, then the first positioning information includes RSRP values ​​corresponding to each PRS transmission beam, etc.

[0201] For example, the fourth message may include fourth indication information to indicate the reporting method. The terminal determines how to report the first location information to the serving base station based on this fourth indication information. For instance, if the fourth indication information indicates periodic reporting, the terminal, after receiving the fourth message, sends the first location information to the serving base station multiple times according to the reporting period. Alternatively, if the fourth indication information indicates triggered reporting, the terminal, after receiving the fourth message, sends the first location information to the serving base station once.

[0202] In some other embodiments, the fourth message may include the third instruction information and the fourth instruction information, as detailed in the description of the third message, the first instruction information and the second instruction information described above, which will not be repeated here.

[0203] S603, The terminal determines the first location information.

[0204] It should be understood that after receiving the fourth message, the terminal may, for example, measure the PRS sent by each base station to obtain positioning measurement results. Then, based on the third and / or fourth indication information included in the fourth message, the terminal determines first positioning information from the positioning measurement results and sends the first positioning information to the serving base station.

[0205] It should be understood that prior to S603, the terminal should also perform a measurement step, namely, measuring the downlink reference signal sent by the serving base station, or measuring the downlink reference information sent by the serving base station and at least one neighboring base station.

[0206] For example, in S603a, the terminal measures the PRS sent by each base station.

[0207] As an alternative to S603a, S603b involves the terminal measuring the CSI-RS transmitted by each base station. Since the terminal only needs to perform one step of either S603a or S603b, it can achieve the same result. Figure 6 S603b is indicated by a dashed line, which represents the optional step.

[0208] In this embodiment of the application, the information exchanged between the terminal and the LMC, such as positioning measurement results and location information request messages, is carried by NRPPa signaling, which can shorten the positioning cycle of the terminal and make it suitable for scenarios that require frequent knowledge of the terminal's location.

[0209] Please see Figure 7 This is a flowchart of the uplink / downlink positioning method provided in the embodiments of this application. In the following description, this method will be applied to... Figures 2-4 The example shown is a communication system. Furthermore, this method can be executed by three communication devices, such as a first communication device, a second communication device, and a third communication device. For ease of explanation, the following description assumes that the method is executed by a network device, a terminal, and a location management device; that is, the first communication device is a network device, the second communication device is a terminal, and the third communication device is a location management device. It should be noted that the embodiments in this application are only illustrative of... Figures 2-4 Taking a communication system as an example, this method is not limited to this scenario. It should be understood that in uplink and downlink positioning scenarios, the measurement of uplink reference signals sent by the terminal by each base station is also involved, so this method may involve more network devices. For example, this method involves a first network device, at least one second network device, etc. It should be understood that the current terminal is currently connected to one network device (this network device can be called the serving base station). For ease of description, the first network device will be referred to as the serving base station below, and the second access network device can be called a neighboring cell base station. In this paper, the positioning management device can be an LMF network element. It should be understood that in future communications such as 6G, the positioning management device can still be an LMF network element, or have other names; this application embodiment does not limit this.

[0210] Specifically, the detailed process of the positioning method provided in this application embodiment is described as follows:

[0211] S701. The terminal sends a first message to the serving base station, and the serving base station receives the first message, wherein the first message includes second location information, and the second location information is carried in RRC signaling.

[0212] S702, The serving base station sends a second message to the LMF, and the LMF receives the second message, wherein the second message is carried on NRPPa signaling, the second message includes third positioning information, the third positioning information includes the second positioning information, and the third measurement result obtained by the serving base station in measuring the second reference signal and the third reference.

[0213] As mentioned above Figure 5 and Figure 6 The process is similar. The third location information exchanged between the terminal and the LMF is carried by NRPPa signaling, which can shorten the reporting cycle of location information compared to carrying it by LPP signaling.

[0214] It should be understood that the second and third positioning information are similar to the aforementioned first positioning information. The second positioning information is only a portion of the information required by the positioning terminal. Other positioning information required to complete the terminal's positioning process can be found in existing technologies and will not be elaborated here. The difference from the first positioning information is that, in this embodiment, the second positioning information includes a second measurement result obtained by the terminal measuring a second reference signal and a third reference signal. The third positioning information includes a third measurement result obtained by the serving base station measuring the second and third reference signals. It should be understood that the second reference signal is a downlink reference signal, which can be a PRS or CSI-RS, and the third reference signal can be an uplink reference signal, which can be an SRS.

[0215] In some embodiments, the information elements carried by the second measurement result (hereinafter referred to as information elements) may include the UE Rx-Tx time difference within the terminal, which can be used for Multi-RTT positioning. The information elements carried by the third measurement result (hereinafter referred to as information elements) may include the gNBRx-Tx time difference within the base station, which can be used for Multi-RTT positioning.

[0216] The third positioning information is similar to the first positioning information. Besides including the second positioning signal and the second measurement results, it may also include a positioning method, such as Multi-RTT positioning. It should be understood that the third positioning information may also include multiple positioning methods, such as Multi-RTT positioning and other possible positioning methods (e.g., one or more of OTDOA, DL-AOA, and DL-AOD positioning methods) for joint positioning. It should be understood that if the third positioning information includes more than one positioning method, then the third positioning information should include measurement results corresponding to each positioning method, such as RSRP values, RSTD values, and angles of arrival (Angles of Arrival) or more.

[0217] Similarly, the third location information is similar to the first location information and may also include error information and a neighboring cell index list. For details, please refer to the aforementioned description of the first location information, which will not be repeated here.

[0218] After obtaining the second positioning measurement result, the terminal can send the second positioning information, including the second positioning measurement result, to the serving base station. In some embodiments, the terminal can send the second positioning information to the serving base station via RRC signaling. Since the reporting period of RRC signaling (typically 160ms) is shorter than the reporting period of LPP signaling (typically 250ms), the first positioning information exchanged between the terminal and the serving base station in this embodiment of the application is transmitted via RRC signaling, which helps to shorten the reporting period of the terminal's positioning information.

[0219] After receiving the second positioning information, the serving base station sends the third positioning information, which includes the second positioning information and the third measurement result, to the LMF so that the LMF can calculate the terminal's location based on the third positioning information.

[0220] It should be understood that prior to S701, the LMF collected the terminal's location information before locating the terminal, and this method could also perform the following steps:

[0221] S7011, LMF and terminal interactive positioning assistance information.

[0222] Specifically, 701a is the same as S601a, so it will not be repeated here.

[0223] S7012, LMF sends a third message to the serving base station, the serving base station receives the third message, the third message includes third indication information and / or fourth indication information, the third message is carried in NRPPa signaling, wherein the third indication information is used to instruct the serving base station to report third location information, and the fourth indication information is used to instruct the serving base station to request second location information from the terminal.

[0224] The third indication information is similar to the first indication information mentioned above; its specific implementation can be found in the implementation of the first indication information, and will not be repeated here. The difference between the third and first indication information is that the positioning method included in the third indication information can be Multi-RTT positioning. Similarly, the fourth indication information is similar to the second indication information mentioned above; its specific implementation can be found in the implementation of the first indication information, and will not be repeated here.

[0225] It should be understood that the second positioning information corresponds to the fourth indication information, and the third positioning information corresponds to the third indication information. For example, the positioning method included in the third indication information may be Multi-RTT positioning, and the third positioning information may include the second measurement result and the third measurement result. For details, please refer to the aforementioned correspondence between the first positioning information and the first indication information, or the correspondence between the first positioning information and the second indication information.

[0226] It should be understood that before requesting the terminal's second location information from the serving base station, the LMF can interact with the terminal to exchange location assistance information. For example, the LMF needs to inform the terminal which cells are being measured. Since the PRS configurations of different cells are different, the LMF also needs to inform the terminal of the PRS configuration for each cell.

[0227] S7013, The serving base station sends a fourth message to the terminal, and the terminal receives the fourth message. The fourth message is used to request the second location information and is carried in RRC signaling.

[0228] Specifically, S7013 is the same as S602, so I will not go into details here.

[0229] S7014, The terminal measures the second reference signal and the third reference signal.

[0230] It should be understood that after receiving the fourth message, the terminal may, for example, measure the second reference signals sent by each base station and the third reference signals sent to each base station to obtain a second measurement result. Then, based on the third indication information and / or the fourth indication information included in the third message, the terminal sends second positioning information, including the second measurement result, to the serving base station.

[0231] S703 and LMF determine the terminal's location based on third-party positioning information.

[0232] LMF can calculate the terminal's location based on third location information and other possible location information using location calculation methods. For example, LMF can determine the terminal's location based on third location information and a fourth measurement result obtained from measurements of the second and third reference signals by at least one neighboring base station.

[0233] In one possible implementation, at least one neighboring base station can send the fourth measurement result to the LMF, or it can send the fourth measurement result to the serving base station, which then sends the fourth measurement result to the LMF. Specific examples are given below for each implementation.

[0234] Please see Figure 8 This is a flowchart illustrating an example of a positioning method provided in an embodiment of this application. The positioning process takes, for example, at least one neighboring base station sending a fourth measurement result to the LMF. The process includes:

[0235] S801, The terminal interacts with the LMF to obtain positioning assistance information.

[0236] The specific implementation method is the same as... Figure 7 The S7011 mentioned here will not be discussed further.

[0237] S802 and LMF send a third message to the serving base station, which is carried in NRPPa signaling.

[0238] The specific implementation method is the same as... Figure 7 The S7012 in the text will not be discussed further here.

[0239] S803, The serving base station sends a fourth message to the terminal, which is carried in RRC signaling.

[0240] The information elements carried in this fourth message may include the location method and the reporting method. The specific implementation method is the same as... Figure 7 The S7013 in the text will not be discussed further here.

[0241] S804. The serving base station configures the time and frequency resources of SRS for the terminal and instructs the terminal to send SRS according to the time and frequency resources configured by the serving base station.

[0242] For example, the serving base station can notify the terminal via RRC signaling of the time and frequency resources of the SRS configured by the serving base station for the terminal, and the terminal sends the SRS according to the time and frequency resources configured by the serving base station.

[0243] S805. The serving base station sends a location response message to the LMF. This location response message is used to instruct the serving base station to configure SRS resources for the terminal.

[0244] For example, the serving base station can send a location response message to the LMF via NRPPa signaling to further reduce latency during the location process.

[0245] S806 and LMF send SRS measurement requests to at least one neighboring base station via NRPPa signaling.

[0246] It should be understood that the embodiments of this application are used for uplink and downlink positioning, which requires measurement of base stations. In the embodiments of this application, the LMF sends an SRS measurement request to at least one neighboring base station via NRPPa signaling, which can further reduce the latency in the positioning terminal process.

[0247] S807: The terminal measures the PRS sent by each base station.

[0248] It should be noted that the execution order of S806 and S807 is not limited in this embodiment.

[0249] S808: The terminal sends the second location information to the serving base station via RRC signaling.

[0250] For details, please refer to the following: Figure 7 The relevant embodiments of S701 will not be described in detail here.

[0251] S809, the serving base station sends the third location information to the LMF via NRPPa signaling.

[0252] S810, at least one neighboring base station sends the fourth measurement result to the LMF, which is carried in NRPPa signaling.

[0253] It should be understood that at least one neighboring base station can send the second positioning information to the LMF via NRPPa signaling to minimize the positioning terminal cycle. It should be noted that the execution order of S809 and S810 is not limited in this embodiment.

[0254] S811 and LMF calculate the terminal's position based on the third positioning information and the fourth measurement result.

[0255] It should be understood that if there is no measurement of neighboring base stations, then the LMF calculates the terminal's location based on third-party positioning information.

[0256] In another embodiment, as an alternative to S810, in S812, at least one neighboring base station can send the fourth measurement result to the serving base station via the Xn interface. In this case, in S809, the third location information sent by the serving base station to the LMF includes the fourth measurement result. And in S806, the SRS measurement request sent by the LMF to at least one neighboring base station includes a neighboring cell index list to inform at least one second network device which first network device to report the third measurement result to. It should be understood that S812 is an optional solution, therefore in Figure 8 The image is indicated by a dashed line.

[0257] The above embodiments can be combined with each other to achieve different technical effects.

[0258] The methods provided in the embodiments of this application above are described from the perspective of the interaction between the terminal, network device, and location management device.

Whether a particular function is executed in the form of hardware structures, software modules, or a combination of hardware structures and software modules depends on the specific application and design constraints of the technical solution.
