Description

Technical Field

[0001] The present application relates to the field of communication technology, and in particular to a positioning method and device. Background Art

[0002] With the rapid development of communication technology, high-precision positioning has gradually been identified as an important research project of the 3rd Generation Partnership Project (3GPP). Among them, carrier phase positioning technology is one of the main methods to achieve high-precision positioning. It measures the distance with integer ambiguity by measuring the carrier phase change of the positioning reference signal from the transmitter to the receiver, thereby obtaining high-precision positioning results.

[0003] However, in scenarios such as the Internet of Things and smart wearables, some terminal devices are limited by size, cost, etc., and their capabilities (such as working bandwidth, etc.) are reduced compared to those of conventional terminal devices. For these reduced capability (RedCap) terminal devices, when participating in positioning, they may need to use frequency hopping to receive positioning reference signals. The carrier phase measurement may be at multiple frequency points and cannot be differentiated from the carrier phase measurement results of the positioning auxiliary device to achieve high-precision positioning. Summary of the invention

[0004] The present application provides a positioning method and device, in order to support a positioning auxiliary device to report carrier phase measurement results with the same granularity as a reduced-capability terminal device, thereby achieving high-precision positioning.

[0005] In a first aspect, an embodiment of the present application provides a positioning method, which can be performed by a positioning assistance device, the method comprising: measuring a positioning reference signal from a second communication device according to a frequency configuration or a frequency hopping configuration to obtain a first measurement result, wherein the frequency configuration or the frequency hopping configuration is determined according to the capability of the first communication device, and the first measurement result includes at least one carrier phase measurement result; sending the first measurement result to a positioning management device, and the first measurement result is used to locate the first communication device.

[0006] For example: For frequency configuration or frequency hopping configuration, the positioning management device can send the frequency configuration or frequency hopping configuration to the positioning assistance device by carrying information (or message) of the frequency configuration or frequency hopping configuration, and can also indicate the frequency configuration or frequency hopping configuration to the positioning assistance device through indication information for indicating the frequency configuration or frequency hopping configuration (such as indication information carrying an index corresponding to the frequency configuration or frequency hopping configuration). This application does not limit the specific manner in which the positioning assistance device obtains the frequency configuration or frequency hopping configuration from the positioning management device.

[0007] In the above positioning method, the first communication device can be a terminal device (such as a RedCap terminal device), a component of a terminal device (such as a processor, a chip, or a chip system, etc.), or a device used in conjunction with a terminal device; the second communication device can be a network device, a component of a network device (such as a processor, a chip, or a chip system, etc.), or a device used in conjunction with a network device.

[0008] Through the above method, the positioning assistance device can obtain the frequency hopping configuration or frequency point configuration related to the first communication device, and measure the positioning reference signal from the second communication device according to the frequency hopping configuration or frequency point configuration, so that the positioning assistance device can obtain the carrier phase measurement result with the same granularity as the first communication device, and support high-precision positioning of the first communication device.

[0009] In one possible design, before measuring the positioning reference signal from the second communication device according to the frequency configuration or the frequency hopping configuration, the method also includes: receiving the frequency configuration or the frequency hopping configuration from the positioning management device; wherein, when the first communication device is a reduced capability RedCap terminal device, receiving the frequency hopping configuration from the positioning management device; when the first communication device is a non-RedCap terminal device, receiving the frequency configuration from the positioning management device.

[0010] Through the above design, it is supported to send different frequency domain related information to the positioning assistance device according to the type of the first communication device, so as to support the positioning assistance device to report the carrier phase measurement result with the same granularity as the first communication device.

[0011] In one possible design, the frequency hopping configuration includes configuration information of multiple frequency hopping (or corresponds to multiple frequency hopping); when there are multiple carrier phase measurement results, the multiple carrier phase measurement results correspond to multiple frequency hopping; when there is one carrier phase measurement result, one carrier phase measurement result corresponds to one frequency hopping among the multiple frequency hoppings.

[0013] Through the above design, it is possible to support reporting of a carrier phase measurement result for each frequency hopping, as well as reporting of a carrier phase measurement result for the entire frequency hopping (multiple frequency hopping), which is beneficial to meeting different measurement requirements for the positioning reference signal when the first communication device adopts a frequency hopping method to receive the positioning reference signal.

[0080] Figure 1 The following is a schematic diagram of the architecture of a communication system applicable to the embodiments of the present application. Figure 1 As shown, the communication system 1000 includes a radio access network (RAN) 100 and a core network (CN) 200. Optionally, the communication system 1000 may also include the Internet 300. The RAN 100 includes at least one network device (such as Figure 1 110a and 110b in, collectively referred to as 110) and at least one terminal device (such as Figure 1 RAN 100 may also include other RAN nodes, such as wireless relay equipment and / or wireless backhaul equipment ( Figure 1 The terminal device 120 is connected to the network device 110 in a wireless manner. The network device 110 is connected to the core network 200 in a wireless or wired manner. The core network device in the core network 200 and the network device 110 in the RAN 100 may be different physical devices, or may be the same physical device that integrates the core network logical functions and the radio access network logical functions.

[0081] RAN 100 may be a cellular system related to the 3rd Generation Partnership Project (3GPP), such as 4G, 5G, or an evolved system after 5G (such as a 6G mobile communication system). RAN 100 may also be an open access network (open RAN, O-RAN or ORAN), a cloud radio access network (cloud radio access network, CRAN). RAN 100 may also be a communication system that integrates two or more of the above systems.

[0082] The network device 110 is a node in the RAN, which can also be called an access network device, or a RAN node (or device). The network device 110 is used to help the terminal device achieve wireless access. The multiple network devices 110 in the communication system 1000 can be nodes of the same type or different types. In some scenarios, the roles of the network device 110 and the terminal device 120 are relative, for example, Figure 1The network element 120i may be a helicopter or a drone, which may be configured as a mobile base station. For the terminal devices 120j that access the RAN 100 through the network element 120i, the network element 120i is a base station; but for the base station 110a, the network element 120i is a terminal device. The network device 110 and the terminal device 120 are sometimes referred to as communication devices, for example Figure 1 The network elements 110a and 110b may be understood as communication devices having base station functions, and the network elements 120a-120j may be understood as communication devices having terminal equipment functions.

[0083] In one possible scenario, the network equipment may be a base station (BS), an evolved NodeB (eNodeB), a transmitting and receiving point (TRP), a transmitting point (TP), a next generation NodeB (gNB), a base station in a future mobile communication system, a satellite, an integrated access and backhaul (IAB) node, a mobile switching center, or a network device in a non-terrestrial network (NTN) communication system, that is, it may be deployed on a high altitude platform or satellite, etc. The network equipment may be a macro base station (such as Figure 1 110a in), micro base stations or indoor stations (such as Figure 1 110b in the example above), a relay node or a donor node, or a wireless controller in a CRAN scenario.

[0084] In another possible scenario, multiple network devices collaborate to assist the terminal device in achieving wireless access, and different network devices respectively implement part of the functions of the base station. For example, the network device may be a centralized unit (CU), a distributed unit (DU), a CU-control plane (CP), a CU-user plane (UP), or a radio unit (RU). The CU and DU may be set separately, or may be included in the same network element, such as a baseband unit (BBU). The RU may be included in a radio frequency device or a radio frequency unit, such as a remote radio unit (RRU), an active antenna unit (AAU), or a remote radio head (RRH). It is understandable that the network device may be a CU node, a DU node, or a device including a CU node and a DU node. In addition, the CU may be divided into a network device in the access network RAN, or the CU may be divided into a network device in the core network CN, without limitation here.

[0085] In different systems, CU (or CU-CP and CU-UP), DU or RU may also have different names, but those skilled in the art can understand their meanings. For example, in the O-RAN system, CU may also be called O-CU (open (open, O) CU), DU may also be called O-DU, CU-CP may also be called O-CU-CP, CU-UP may also be called O-CU-UP, and RU may also be called O-RU. For the convenience of description, CU, CU-CP, CU-UP, DU and RU are used as examples for description in this application. Any unit of CU (or CU-CP, CU-UP), DU and RU in this application may be implemented by a software module, a hardware module, or a combination of a software module and a hardware module.

[0088] The embodiments of the present application do not limit the device form of the terminal device. The device for realizing the function of the terminal device can be the terminal device; it can also be a device that can support the terminal device to realize the function, such as a chip system.

[0090] Among them, the AMF network element (or AMF module or AMF component) can be used to be responsible for the access control and mobility management of terminal devices accessing the operator's network. For example, the functions that can be implemented by the AMF network element include but are not limited to mobile state management, allocation of user temporary identity, authentication and authorization of users, etc. The SMF network element (or SMF module or SMF component) can be used to implement functions such as session management, execution of control policies issued by the policy control function (PCF), selection of user plane function (UPF) network elements, and allocation of Internet protocol (IP) addresses of terminal devices. The user plane gateway can refer to a server with functions such as mobility management, routing, and forwarding of user plane data, which is generally located on the network side, such as a serving gateway (SGW) or a packet data network gateway (PGW) or a UPF network element. The positioning management device has a positioning function.

Figure 2AAs shown, the network architecture of the communication system is introduced by taking the positioning network architecture based on the next generation radio access network (NG-RAN) as an example. The network architecture of the communication system may include three parts: NG-RAN, terminal equipment and core network.

[0092] Among them, the core network may include LMF network elements (or LMF modules or LMF components), AMF network elements, service location protocol (SLP) and evolved serving mobile location center (E-SMLC). The positioning server, namely the LMF network element, is connected to the AMF network element, and the LMF network element and the AMF network element are connected through the NLs interface. The terminal device communicates with the serving base station through the Uu link (or interface); Ng-eNB is a base station in the long term evolution (LTE) communication system, and gNB is a base station in the 5G new radio (NR) communication system, and the base stations communicate through the Xn interface; the base station and the AMF network element communicate through the NG-C interface, and the AMF network element is equivalent to a router for the communication between the gNB and the LMF network element; the LMF network element can realize the location estimation of the terminal device, and the AMF network element and the LMF network element communicate through the NLs interface. The LMF network element is responsible for supporting different types of location services related to the terminal device, including positioning the terminal device and transmitting auxiliary data to the terminal device. The LMF network element can calculate the location of the terminal device based on the measurement results of other devices. The AMF network element can receive location service requests related to the terminal device from the 5th generation core network location services (5GC LCS) entity, or the AMF network element itself can also start some location services on behalf of a specific terminal device and forward the location service request to the LMF network element. After obtaining the location information returned by the terminal device, the relevant location information is returned to the 5GC LCS entity.

[0093] Exemplarily, NG-RAN may include next generation node B (gNB), next generation evolved node B (ng-eNB), etc. gNB and ng-eNB are connected via an Xn interface, and LMF is connected to ng-eNB / gNB via an NG-C interface. Optionally, gNB may be a base station or access point of various forms, or gNB may be a TRP or a transmission measurement function (TMF) for transmitting and receiving reference signals. ng-eNB may be a base station or access point of various forms, or ng-eNB may be a TRP for transmitting and receiving reference signals.

[0094] Optionally, for one or more network devices on the NG-RAN side (such as ng-eNB, gNB and other base stations), resources for sending downlink positioning reference signals can be configured. Afterwards, the one or more network devices can send a downlink positioning reference signal to the terminal device, the terminal device measures the downlink positioning reference signal, and feeds back the measurement result of the downlink positioning reference signal to the LMF network element to support positioning. Exemplarily, the downlink positioning reference signal may include, but is not limited to: positioning reference signal (PRS), cell common reference signal (CRS) or channel state information (CSI)-RS, etc. For example, taking the downlink positioning reference signal as PRS as an example, the PRS resources can be configured at the cell level, that is, PRS resources are configured for each cell separately. After the terminal device re-establishes the radio resource control (RRC) connection with the target cell, the base station of the target cell can configure PRS resources for the target cell, and the terminal device obtains the PRS resources configured for the target cell to receive and measure PRS on the PRS resources. In addition, for one or more terminal devices (or one or more positioning auxiliary nodes) on the terminal device side, resources for sending uplink positioning reference signals can be configured. Afterwards, the one or more terminal devices (or one or more positioning auxiliary nodes) can send uplink positioning reference signals to the network device, the network device measures the uplink positioning reference signals, and feeds back the measurement results of the uplink positioning reference signals to the LMF network element to support positioning.

[0095] based on Figure 1 The communication system architecture shown in Figure 2B The following is an exemplary diagram of another network architecture of a communication system to which the present application is applicable. Figure 2B As shown, the network architecture of the communication system is introduced by taking the communication and positioning network architecture based on the PC5 interface as an example. The network architecture of the communication system may include three parts: RAN equipment, at least one terminal device (such as terminal device A and terminal device B, etc.) and the core network. Among them, the specific functions of the RAN equipment, terminal equipment, AMF network element and LMF network element and the connection relationship between the various devices / network elements can be found in the above Figure 1 or Figure 2A The introduction of the relevant parts will not be repeated here.

[0096] In addition, Figure 2A The difference is, Figure 2B The terminal device included in the illustrated network architecture has an LMC (also referred to as UE-LMC) added thereto. The specific deployment method of the LMC is to set it inside the terminal device, such as in terminal device A or in terminal device B. In this network architecture, the LMC is a function inside the terminal device, so there is no need to introduce a new interface. Among them, the LMC is a component / application deployed on the terminal device with some functions of the LMF network element, which is used to support positioning services on the PC5 interface.

[0097] It should be understood that the above Figure 2A , Figure 2B These are several exemplary descriptions of communication systems to which the embodiments of the present application are applicable, and do not specifically limit the type, quantity, connection method, etc. of network elements included in the communication system to which the present application is applicable.

[0098] In order to facilitate understanding by those skilled in the art, some terms in this application are explained below.

[0099] 1) Positioning technology based on time or angle. In the 3GPP standard, multiple positioning technologies are supported, such as downlink (DL)-time difference of arrival (TDOA), DL-angle of departure (AOD), uplink (UL)-TDOA, UL-angle of arrival (AOA), and multi-round triptime (multi-RTT). Among them, DL-TDOA, UL-TDOA and multi-RTT algorithms are positioning technologies based on arrival time, that is, the receiving end is required to measure the arrival time of the signal sent by the sending end, and then convert it into the distance information between the two, and finally obtain the position of the target to be located. DL-AOD and UL-AOA are positioning technologies based on angles, that is, the receiving end measures the arrival angle of the signal sent by the sending end, and then infers the position of the receiving end based on the angle information between the receiving end and multiple sending ends with known positions. The following takes the UL-TDOA positioning technology as an example to introduce how to calculate the position of the target to be located.

[0100] Taking the positioning of UE through three base stations as an example, the positions (i.e. coordinates) of the three base stations are known. Here, the coordinates of the i-th base station are defined as (x i ,y i ), the coordinates of the UE to be located are (x UE ,y UE ), and take the first base station as the reference base station, assuming that the arrival time of the reference signal measured by the other two base stations is t i , then the arrival time difference of the reference signal measured by any base station and the reference base station is Δt i1 According to the definition of a hyperbola (the distance from two fixed points is a constant), the target is located on the hyperbola with two base stations as foci, and the following set of equations can be listed:

[0101]

[0102]

[0103] In the above two equations, c is the speed of light, because there are only two unknowns (x UE ,y UE ), and solve equations (1) and (2) together to obtain the location coordinates of the target UE.

[0104] 2) Carrier phase positioning technology. The 3GPP R18 standard version discusses carrier phase positioning technology. Carrier phase positioning technology is one of the main methods of high-precision positioning. It measures the distance with integer ambiguity by measuring the carrier phase change of the reference signal from the transmitter to the receiver. Taking the 3 GHz RF signal as an example, the corresponding carrier wavelength is 0.1 meters; therefore, when the integer ambiguity of the carrier phase can be correctly solved, the carrier phase ranging accuracy can theoretically reach the centimeter to millimeter level, thereby obtaining a high-precision positioning result. Specific ranging such as Figure 3 As shown. Figure 3 Where d is the distance between the reference signal transmitter and receiver. is the carrier phase measurement information measured by the receiving end, N is the integer ambiguity, N is a positive integer, and the value of N is used to indicate that the distance d includes N carrier integers, λ is the wavelength of the carrier, and the distance d is related to the carrier phase The following equation is satisfied:

[0105]

[0106] The positioning reference unit (PRU) was introduced in the 3GPP R17 standard version to assist in improving positioning performance. The positioning reference signal is measured using a positioning reference unit with a known position, and a double difference equation is constructed between different base stations and between the positioning terminal device and the positioning reference unit to eliminate the influence of non-ideal factors and improve positioning accuracy. R18 carrier phase positioning also supports the use of PRU to assist in carrier phase measurement and improve carrier phase positioning accuracy.

[0107] The double difference carrier phase can be located by the following method:

[0108] Assuming that both the UE and the base station have synchronization / phase errors, the phase measured by the UE or the base station can be expressed as:

[0109] The random initial phase error of station i, is the phase integer ambiguity between UE and base station i.

[0110] By making a difference between different base stations, the phase difference of arrival (PDOA) can be obtained to eliminate the random initial phase φ of the UE. t :

[0111]

[0112] Similarly, for PRU, PDOA can be measured, which can eliminate the random initial phase φ of PRU. p :

[0113]

[0114] By making a difference between UE and PRU, we can get the double difference PDOA:

[0115]

[0116] The random initial phase φ on the base station side can be eliminated (i) And the time synchronization error Δ (ij) ,get According to the information of multiple base stations, multiple double-difference PDOA measurement values ​​can be obtained, and the simultaneous equations can be used to calculate the UE position to be located according to the known PRU position and base station position.

[0117] Reference Figure 4 The double difference carrier phase positioning schematic diagram shown in FIG. 1 can be obtained based on the base station 1-base station 3 ( Figure 4 In the example of BS1-BS3, the phase of the PRU sent by the UE is determined by using the double-difference carrier phase positioning technology to determine the position of the UE. In addition, in the double-difference carrier phase positioning, the UE and the PRU are usually required to measure the PRS sent by the base station at the same time, so that the random initial phase φ on the base station side can be eliminated by differential means. (i) And the time synchronization error Δ (ij) , because the random initial phase φ on the base station side (i) And the time synchronization error Δ (ij) It is an error term that varies with time, so the UE and PRU are required to measure the PRS sent by the base station at the same time.

[0118] 3) PRU. PRU can also be called reference device, positioning reference device (PRD), reference user equipment (reference UE), differential device (differential device), positioning differential device (PDD), etc. The positioning reference unit can be a terminal device and / or an access network device and / or a part of an access network device (for example, UE, gNB, eNB, central unit (CU), distributed unit (DU), transmitting and receiving point TRP, etc.). PRU can be used to assist location management network elements (such as LMF network elements) or terminal devices to achieve terminal device positioning. The location information of PRU may be known, may be location information measured, calculated or estimated by a positioning method, or may be location information configured by an operator, which is not limited in this application.

[0119] PRU can support some or all of the following functions: (1) Measure the downlink positioning reference signal and report the relevant measurement information to the location management network element. The location management network element in this application can be an LMF network element, a location server, an eLMF, or other network elements with similar functions. This application does not limit this name. Among them, the reported related measurement information may include: reference signal carrier phase RSCP, reference signal carrier phase difference RSCPD, reference signal time difference (reference signal time difference, RSTD), receive and send time difference (Rx-Tx timedifference), etc.; (2) A positioning reference signal can be sent to an access network device (e.g., gNB, eNB) or a part of an access network device (e.g., TRP), so that the access network device or a part of the access network device measures and reports the measurement information related to the positioning reference device to the location management network element. Among them, the reported related measurement information may include: carrier phase measurement results (such as carrier phase or multi-frequency carrier phase difference, etc.), time-related measurement results (such as reference signal time difference (RSTD), receive and send time difference (Rx-Tx timedifference), reference signal received power (RSRP), etc.

[0120] 4) Measurement time window: an agreement was reached in the 3GPP R18 standard meeting. The LMF network can configure an indicated measurement time window for the UE or PRU, instructing the UE and PRU to measure and report the downlink PRS resource set within this measurement time window, so that the UE and PRU can measure simultaneously. For this measurement time window, the standard stipulates that the duration of this measurement time window can be {1,2,4,6,8,12,16} time slots, and the configured time windows can have {1,2}. There can be one or more frequency resource sets in a time window.

[0121] 5) Reduced capability (RedCap) UE measures the positioning reference signal. RedCap UE can also be called simplified capability UE, low capability UE, etc. Due to the limitations of size and cost, the working bandwidth of RedCap UE may be small, and frequency hopping is required to receive PRS. Figure 5 The schematic diagram of frequency hopping receiving positioning reference signal shown in FIG. Figure 5Taking TRP as an example, a large-bandwidth PRS can be sent in different time domain units (such as time domain unit t1-time domain unit t5). When receiving, the RedCap UE receives small-bandwidth PRS at different frequency points (such as frequency point f1-frequency point f5) in different time domain units, and obtains large-bandwidth measurement quantities after splicing, such as time of arrival (TOA) or carrier phase measurement quantities, where each frequency hop belongs to a hop.

[0122] However, when positioning is performed based on carrier phase positioning technology, unconventional terminal devices such as RedCap terminal devices (such as RedCap UE) usually need to use frequency hopping and other methods to receive positioning reference signals. The frequency point of the measured carrier phase may not be at or not entirely at the center frequency point of the positioning reference signal, and it is impossible to differentiate it from the carrier phase of the positioning auxiliary device to achieve high-precision positioning.

[0123] Based on this, the present application provides a positioning method and apparatus, in order to support the RedCap terminal device and the PRU to report the frequency-hopping carrier phase of the same granularity, so as to achieve high-precision positioning.

[0124] In addition, it should be understood that the ordinal numbers such as "first" and "second" mentioned in the embodiments of the present application are used to distinguish multiple objects, and are not used to limit the size, content, order, timing, priority or importance of the multiple objects. For example, the first frequency hopping configuration and the second frequency hopping configuration do not mean that the priorities or importance of the two frequency hopping configurations are different.

[0125] In the embodiments of the present application, the number of nouns, unless otherwise specified, means "singular noun or plural noun", that is, "one or more". "At least one" means one or more, and "plural" means two or more. "And / or" describes the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone, where A and B can be singular or plural. The character " / " generally indicates that the previous and next associated objects are in an "or" relationship. For example, A / B means: A or B. "At least one of the following" or similar expressions refers to any combination of these items, including any combination of single or plural items. For example, at least one of a, b, or c means: a, b, c, a and b, a and c, b and c, or a and b and c, where a, b, c can be single or multiple.

[0126] Figure 6 A schematic diagram showing a positioning method provided by an embodiment of the present application is exemplified. The method is applicable to Figure 1 , Figure 2A and Figure 2BOptionally, the first communication device may be Figure 1 , Figure 2A and Figure 2A The terminal device shown in the figure or a component (such as a chip or an integrated circuit) capable of supporting the terminal device to implement the functions required by the method; the second communication device may be Figure 1 , Figure 2A and Figure 2A The RAN device shown in the figure or a component (such as a chip or integrated circuit) that can support the RAN device to implement the functions required by the method. The positioning auxiliary device can be Figure 1 , Figure 2A and Figure 2A The positioning management device may include a positioning assistance node (such as a PRU) not shown in the figure or a component (such as a chip or an integrated circuit) that can support the positioning assistance node to implement the functions required by the method. Figure 2A and Figure 2B The LMF network element shown, or a component (such as a chip or integrated circuit) that can support the LMF network element to implement the functions required for the method.

[0127] In order to facilitate the introduction of the technical solution provided by the embodiment of the present application, the following is an example of the process of implementing the positioning method through interaction between the first communication device, the second communication device, the positioning auxiliary device and the positioning management device. Figure 6 As shown, the method includes:

[0128] S601: The positioning management device sends a frequency configuration or a frequency hopping configuration to the positioning assistance device, and the positioning assistance device receives the frequency configuration or the frequency hopping configuration accordingly, wherein the frequency configuration or the frequency hopping configuration is determined according to the capability of the first communication device.

[0129] Exemplary: the capability of the first communication device may include the capability of the first communication device to receive signals (such as positioning reference signals), such as the working bandwidth supported by the first communication device for receiving signals, etc., and may also include the positioning-related capabilities of the first communication device (such as supported positioning methods or algorithms), measurement capabilities (such as supported measurement quantities for positioning reference signals), etc. For the capability of the first communication device, the positioning management device may obtain the capability of the first communication device through the LTE positioning protocol capability transfer process; of course, the positioning management device may also obtain the capability of the first communication device through other methods, such as by sending a capability acquisition request to the first communication device, receiving the capability reported by the first communication device, etc. This application does not limit the method by which the positioning management device obtains the capability of the first communication device.

[0130] In an embodiment of the present application, the working bandwidth (or supported bandwidth) of the first communication device and the positioning assistance device may be the same or different. When the positioning assistance device assists in positioning the first communication device, the positioning management device may send a frequency configuration or a frequency hopping configuration to the positioning assistance device based on the capabilities of the first communication device (such as the working bandwidth), so that the positioning assistance device can report the carrier phase measurement results with the same granularity as the first communication device.

[0131] Taking the first communication device as a RedCap terminal device (such as a RedCap UE) and the positioning auxiliary device as an enhanced mobile broadband (eMBB) terminal device (such as an eMBB UE) as an example, refer to Figure 7 The working bandwidth diagram shown in FIG. Figure 7 The positioning reference signal can be sent on multiple frequency domain units (TRP is used as an example), where the bandwidth of each frequency domain unit is, for example, 20 MHz. The positioning auxiliary device can work on multiple frequency domain units and receive the positioning reference signal sent by the second communication device on multiple frequency domain units. However, due to the limited working bandwidth, the RedCap terminal device needs to limit its sending / receiving of positioning reference signals to one frequency domain unit ( Figure 7 The frequency domain unit 2 is taken as an example). The frequency domain unit may be a resource block set (resource block set, RB set), a sub-channel, a sub-band, a physical resource block (physical resource block, PRB), etc.

[0132] In one possible implementation, when the first communication device is an unconventional terminal device such as a RedCap terminal device, and the working bandwidth is smaller than the bandwidth of the second communication device for sending a positioning reference signal, the positioning management device can send the corresponding frequency hopping configuration to the positioning assistance device based on the frequency hopping configuration of the positioning reference signal measured by the first communication device, so that the positioning assistance device can report the carrier phase measurement result with the same granularity as the first communication device.

[0133] Exemplary: Reference Figure 8 As shown, the horizontal direction represents the time domain and the vertical direction represents the frequency domain, the second communication device ( Figure 8 The frequency domain for sending the positioning reference signal is frequency domain unit 1-frequency domain unit 5 (the bandwidth is the bandwidth of 5 frequency domain units from frequency domain unit 1 to frequency domain unit 5), the time domain for sending the positioning reference signal includes time domain unit t1-time domain unit t5, the bandwidth supported by the first communication device is the bandwidth of 1 frequency domain unit, and the first communication device ( Figure 8 In the example of RedCap UE), the positioning reference signal is received by frequency hopping in the time domain unit t1-time domain unit t5. Figure 8 In the embodiment, the first communication device receives a positioning reference signal in the frequency domain unit 1 in the time domain unit t1, receives a positioning reference signal in the frequency domain unit 2 in the time domain unit t2, receives a positioning reference signal in the frequency domain unit 3 in the time domain unit t3, receives a positioning reference signal in the frequency domain unit 4 in the time domain unit t4, and receives a positioning reference signal in the frequency domain unit 5 in the time domain unit t5. The working bandwidth of the first communication device in each time domain unit does not exceed the bandwidth of one frequency domain unit. The first communication device can measure the received positioning reference signal at the frequency points f1 to f5 corresponding to the frequency domain units 1 to 5 in the time domain units t1 to t5. The time domain unit can be a slot, a microslot, a symbol, a subframe, a half frame, and the like.

[0134] It is understandable that in the embodiment of the present application, adjacent time domain units may be continuous or discontinuous in the time domain, such as the above Figure 8 The time domain unit t1 and the time domain unit t2 in the time domain may be continuous or discontinuous in the time domain, and this application does not limit this.

[0135] In addition, the positioning management device may also configure the first communication device to measure the same frequency domain unit (or frequency point) in different time units. Fig. 9 As shown, the horizontal direction represents the time domain and the vertical direction represents the frequency domain. For example, the first communication device can be configured to receive the positioning reference signal in the frequency domain unit 3 in the time domain unit t1, receive the positioning reference signal in the frequency domain unit 3 in the time domain unit t2, receive the positioning reference signal in the frequency domain unit 3 in the time domain unit t3, receive the positioning reference signal in the frequency domain unit 3 in the time domain unit t4, and receive the positioning reference signal in the frequency domain unit 3 in the time domain unit t5. The working bandwidth of the first communication device in each time domain unit does not exceed the bandwidth of one frequency domain unit. The first communication device can measure the received positioning reference signal at the frequency point f3 corresponding to the frequency domain unit 3 in the time domain units t1-t5.

[0136] It should be noted that the above Figure 8 , Fig. 9 The frequency hopping method shown is only an example. It can also be a frequency hopping method in which the first communication device receives a positioning reference signal in the frequency domain unit 3 in the time domain unit t1, receives a positioning reference signal in the frequency domain unit 4 in the time domain unit t2, receives a positioning reference signal in the frequency domain unit 5 in the time domain unit t3, receives a positioning reference signal in the frequency domain unit 1 in the time domain unit t4, and receives a positioning reference signal in the frequency domain unit 2 in the time domain unit t5. This application does not limit the specific frequency hopping method.

[0137] It is understandable that in Figure 8 In the frequency hopping configuration, there are multiple ( Figure 8 5 as an example) frequency hopping configuration information, or the frequency hopping configuration corresponds to multiple ( Figure 8 Taking 5 as an example for frequency hopping, the resources corresponding to any time domain unit and frequency domain unit configured or indicated by the frequency hopping configuration can be referred to as a frequency hop, or a frequency hopping moment, or a frequency hopping frequency point, or a hop, or a hop configuration, etc. For example, the resources corresponding to time domain unit t1 and frequency domain unit 1 (such as time-frequency resources) can be referred to as a frequency hop, or a frequency hopping moment (such as t1), or a frequency hopping frequency point (such as frequency point f1), and so on.

[0138] Exemplarily, the frequency hopping configuration may include one or more of the following information: frequency hopping pattern, frequency hopping time domain unit interval, frequency hopping frequency domain unit interval, starting frequency domain unit of frequency hopping, starting time domain unit of frequency hopping, number of frequency hopping jumps, frequency point order of frequency hopping, etc. Among them, the frequency hopping pattern can also be referred to as a frequency hopping template, a frequency hopping sequence, etc.

[0139] It should be noted that the frequency hopping time domain unit interval can also be referred to as the frequency hopping time interval or the frequency hopping period, and can be understood as the duration or residence time on a frequency hopping frequency domain unit. The frequency hopping frequency domain unit interval can be understood as the offset between the frequency domain units corresponding to two consecutive frequency hops. The starting time domain unit of frequency hopping can be understood as the first frequency domain unit when transmitting in the frequency hopping mode. The starting time domain unit of frequency hopping can be understood as the first time domain unit when transmitting in the frequency hopping mode. It can be understood that the starting frequency domain unit of frequency hopping can default to the frequency domain unit 0 where the second communication device sends the positioning reference signal, or the starting frequency domain unit of frequency hopping can also be other values, and the present application does not limit this.

[0140] It can be understood that the time domain units of multiple frequency hops configured (or corresponding) by the frequency hopping configuration can be located within the measurement time window indicated by the positioning management device for the first communication device (or the positioning assistance device). As an example: the frequency point order indicated by the frequency hopping configuration is frequency point f1 - frequency point f5, and the frequency domain units corresponding to frequency points f1 - f5 are frequency domain units 1 - 5 respectively. Then the specific frequency hopping pattern can be that the first time domain unit within the measurement time window corresponds to frequency domain unit 1, the second time domain unit corresponds to frequency domain unit 2, the third time domain unit corresponds to frequency domain unit 3, the fourth time domain unit corresponds to frequency domain unit 4, and the fifth time domain unit corresponds to frequency domain unit 5. The present application does not limit the specific manner in which the frequency hopping configuration indicates or configures frequency hopping.

[0141] In another possible implementation, for a conventional terminal device such as an eMBB terminal device of the first communication device, when the working bandwidth is not less than the bandwidth of the positioning reference signal sent by the second communication device, the positioning management device can send the corresponding frequency point configuration to the positioning assistance device according to the frequency point configuration for measuring the positioning reference signal of the first communication device, so that the positioning assistance device can report the carrier phase measurement result with the same granularity as the first communication device.

[0142] Exemplary: When the working bandwidth of the first communication device is not less than the bandwidth of the second communication device for sending the positioning reference signal, the positioning management device can send the frequency configuration of the first communication device for measuring the positioning reference signal (such as the frequency of measuring the positioning reference signal) to the positioning assistance device, so that the positioning assistance device can measure the positioning reference signal at the same frequency to obtain the measurement result.

[0143] In some implementations, the positioning management device may also send configuration information of a positioning reference signal to the positioning assistance device, wherein the configuration information of the positioning reference signal may be used to assist the positioning assistance device in measuring the positioning reference signal. Exemplarily, the configuration information of the positioning reference signal may include, but is not limited to, time domain resources, frequency domain resources, signal transmission period, or identification information of the positioning reference signal.

[0144] In addition, the positioning management device may also send a request information (or message) to the positioning assistance device, and the request information (or message) may be used to request the positioning assistance device to measure the reference signal, etc. In addition, the request information (or message) may also include measurement time information for measuring the positioning reference signal. Exemplarily, the measurement time information may include but is not limited to a measurement time window or a measurement timestamp, etc.

[0145] It can be understood that the configuration information and / or request information of the positioning reference signal can be sent together with the frequency configuration or the frequency hopping configuration, and can also be sent before the frequency configuration or the frequency hopping configuration is sent, or after the frequency configuration or the frequency hopping configuration is sent. This application does not limit the order in which the configuration information and / or request information, and the frequency configuration or the frequency hopping configuration are sent.

[0146] Regarding the frequency configuration or the frequency hopping configuration, in a possible implementation, the positioning management device may directly send the frequency configuration or the frequency hopping configuration to the positioning assistance device by carrying the information (or message) of the frequency configuration or the frequency hopping configuration.

[0147] In another possible implementation, the frequency configuration or the frequency hopping configuration may also be indicated to the positioning auxiliary device through indication information for indicating the frequency configuration or the frequency hopping configuration. As an example: the positioning management device may send indication information to the positioning auxiliary device, and the indication information may carry an identifier of the frequency (such as an index) or an identifier of the frequency hopping pattern (such as an index), which may be used to indicate the frequency configuration or the frequency hopping configuration, and the positioning auxiliary device may determine the frequency configuration or the frequency hopping configuration according to the indication information.

[0148] It can be understood that the above-mentioned sending of the frequency configuration or frequency hopping configuration by the positioning management device to the positioning assistance device is only an example. The frequency configuration or frequency hopping configuration can also be determined by other devices (such as a second communication device) and sent to the positioning assistance device, or the frequency configuration or frequency hopping configuration can be determined by the positioning assistance device, and the present application does not limit this.

[0149] S602: The positioning assistance device measures the positioning reference signal from the second communication device according to the frequency configuration or the frequency hopping configuration to obtain a first measurement result, wherein the first measurement result includes at least one carrier phase measurement result.

[0150] In a possible implementation, in the case of receiving a frequency hopping configuration, the positioning assistance device may measure the positioning reference signal from the second communication device according to the frequency hopping configuration to obtain a carrier phase measurement result.

[0151] As an example: See Fig.10 As shown, the horizontal direction represents the time domain, the vertical direction represents the frequency domain, the frequency hopping configuration includes 5 frequency hopping configuration information, the first communication device ( Fig.10 Taking RedCapUE as an example) can receive the reference signal from the second communication device at each hopping frequency, such as the five hopping frequencies corresponding to the time domain unit t1-time domain unit t5, and measure the carrier phase of the positioning reference signal at the five hopping frequencies f1-f5 to obtain the carrier phase measurement results corresponding to the five hopping frequencies. Similarly, the positioning auxiliary device ( Fig.10 In the example of PRU, the carrier phase of the positioning reference signal at the five frequency hopping points f1 to f5 can also be measured in the time domain unit t1 to the time domain unit t5 to obtain the carrier phase measurement results corresponding to the five frequency hopping points (or five frequency hopping points). The carrier phase measurement results may include one or more of RSCP, RSCPD (such as the reference signal carrier phase difference of the positioning reference signal sent by the second communication device and other positioning base stations), multi-frequency carrier phase or multi-frequency carrier phase difference, etc.

[0152] In some implementations, the positioning assistance device may report carrier phase measurement results to the positioning management device for all or part of the frequency hopping corresponding to the frequency hopping configuration.

[0153] Exemplary: the positioning assistance device can report the carrier phase measurement result to the positioning management device for each frequency hopping corresponding to the frequency hopping configuration. That is, if the frequency hopping configuration includes configuration information of multiple frequency hoppings, corresponding to multiple frequency hoppings, the measurement result (such as the first measurement result) sent by the positioning assistance device to the positioning management device may include multiple carrier phase measurement results corresponding to the multiple frequency hoppings. Fig.10As shown, if the frequency hopping configuration includes configuration information of 5 frequency hopping, the measurement result (such as the first measurement result) sent by the positioning assistance device to the positioning management device may include the carrier phase measurement results corresponding to the 5 frequency hoppings respectively.

[0154] The positioning auxiliary device can also report a carrier phase measurement result to the positioning management device for multiple frequency hoppings corresponding to the frequency hopping configuration, that is, if the frequency hopping configuration includes configuration information of multiple frequency hoppings, corresponding to multiple frequency hoppings, the measurement result (such as the first measurement result) sent by the positioning auxiliary device to the positioning management device can only include the carrier phase measurement result corresponding to a certain frequency hopping in the multiple frequency hoppings. Among them, the frequency hopping corresponding to the carrier phase measurement result can be any one of the multiple frequency hoppings corresponding to the frequency hopping configuration, such as the first frequency hopping, the second frequency hopping, etc. in the multiple frequency hoppings corresponding to the frequency hopping configuration. For the frequency hopping corresponding to the reported carrier phase measurement result, it can be defined or configured by a protocol, such as defining the carrier phase measurement result corresponding to the first frequency hopping in the multiple frequency hoppings corresponding to the reporting frequency hopping configuration, reporting the carrier phase measurement result corresponding to the center frequency point of the second communication device sending the positioning reference signal (i.e., the carrier phase measurement result corresponding to the frequency hopping where the center frequency point is located), etc., and the positioning management device can also indicate or configure the reporting of the frequency hopping corresponding to the carrier phase measurement result to the positioning auxiliary device, and this application does not limit this.

[0155] In some implementations, the positioning management device may also send a first indication message to the positioning assistance device to indicate whether the positioning assistance device reports one carrier phase measurement result or multiple carrier phase measurement results. Exemplary: the first indication message may include a 1-bit indication bit, where the indication bit is 0 to indicate reporting one carrier phase measurement result, and the indication bit is 1 to indicate reporting multiple carrier phase measurement results.

[0156] As an example: See Fig.11 As shown, the horizontal direction represents the time domain and the vertical direction represents the frequency domain. The frequency hopping configuration includes configuration information of 5 frequency hoppings. The first communication device can receive the reference signal from the second communication device at each frequency hopping, such as the 5 frequency hoppings corresponding to the time domain unit t1-time domain unit t5, and measure the carrier phase of the positioning reference signal at the frequency point f3 of the 5 frequency hoppings, obtain the carrier phase measurement results corresponding to the 5 frequency hopping frequencies, and report the carrier phase measurement results of the frequency hopping corresponding to the time domain unit t3 (that is, the frequency point f3 corresponding to the time domain unit t3) to the positioning management device. Similarly, the positioning auxiliary device ( Fig.11Taking PRU as an example), the phase of the positioning reference signal at frequency point f3 can also be measured in time domain units t1-time domain units t5 respectively to obtain the carrier phase measurement results corresponding to 5 frequency hopping (or 5 frequency hopping frequency points), and the carrier phase measurement results of the frequency hopping corresponding to the time domain unit f3 (that is, the frequency point f3 corresponding to the time domain unit t3) are reported to the positioning management device.

[0157] It is understandable that before reporting the carrier phase measurement results to the positioning management device, the positioning assistance device (or the first communication device) can also smooth the carrier phase measurement results corresponding to multiple frequency hopping according to the carrier phase measurement results corresponding to multiple frequency hopping respectively, so as to eliminate errors such as noise and improve the accuracy of the carrier phase measurement results.

[0158] In the case of receiving a frequency configuration, the positioning assistance device can measure the carrier phase of the positioning reference signal from the second communication device at the corresponding frequency according to the frequency configuration, and send the carrier phase measurement result to the positioning management device.

[0159] In addition, it can be understood that the positioning assistance device can also measure the positioning reference signal from the second communication device according to the frequency configuration or frequency hopping configuration from the positioning management device to obtain a time measurement result, and the measurement result (such as the first measurement result) reported to the positioning management device can also include the time measurement result. The time measurement result may include one or more of the reference signal arrival time, the reference signal arrival time difference RSTD (such as the time difference between the positioning reference signal sent by the second communication device and other positioning base stations and the like to reach the positioning assistance device), the positioning assistance device reference signal receiving and sending time difference (such as the time difference between the time when the positioning assistance device receives the positioning reference signal from the second communication device and the time when the positioning assistance device sends the positioning reference signal), etc.

[0160] S603: The positioning assistance device sends a first measurement result to the positioning management device, and correspondingly, the positioning management device receives the first measurement result, wherein the first measurement result is used to locate the first communication device.

[0161] For example: The positioning management device can determine the position of the first communication device based on one or more of a double-difference carrier phase-based positioning technology, a time-based positioning technology, etc., based on the first measurement result from the positioning assistance device and the measurement result from the first communication device (such as the measurement result of the first communication device on the positioning reference signal from the second communication device).

[0162] Combine the following Fig.12 The specific example shown above Figure 3The positioning method shown is introduced in detail. In the following example, the positioning reference signal is PRS, the first communication device is UE, the second communication device is a serving base station (that is, the base station to which the serving cell where the UE resides, such as base station A), at least one neighboring base station (that is, the base station to which the neighboring cell of the serving cell where the UE resides, such as base station B), and the positioning management device is an LMF network element. Optionally, the second communication device may also be a TRP, for example, the second communication device is a serving TRP and at least one neighboring TRP.

[0163] Fig.12 The following example shows one of the downlink positioning procedures. Fig.12 As shown, the process includes:

[0164] S1201: The LMF network element obtains UE capabilities through the LTE positioning protocol Capability Transfer process.

[0165] Exemplary: The LMF network element can obtain the UE's positioning-related capabilities, PRS receiving capabilities (such as working bandwidth) and measurement capabilities through the LTE positioning protocol (LTE positioning protocol, LPP) Capability Transfer process.

[0166] S1202: The LMF network element sends information requests to base station A and base station B respectively. Correspondingly, base station A and base station B receive the information requests respectively.

[0167] Optionally, the information request may be used to request to obtain attribute information of base station A (or base station B). Exemplarily, the attribute information may include, but is not limited to, base station identification (such as ID), cell information covered by the base station, location information (such as coordinates), or PRS configuration information.

[0168] S1203: Base station A and base station B send information responses to the LMF network element respectively. Correspondingly, the LMF network element receives information responses from base station A and base station B respectively.

[0169] Optionally, the information response includes attribute information of base station A (or base station B).

[0170] S1204: The LMF network element sends positioning assistance information to the UE and the PRU respectively, and correspondingly, the UE and the PRU respectively receive the positioning assistance information.

[0171] Exemplarily: the positioning assistance information may include at least one of the following: PRS configuration, location information of base station A, location information of base station B, an identifier of base station A or an identifier of base station B, etc.

[0172] S1205: The LMF network element sends location request information (request location information) to the UE and PRU respectively. Correspondingly, the UE and PRU receive the location request information respectively.

[0173] Exemplary: The positioning request information can be used to request the UE (or PRU) to measure PRS. The positioning request information may include measurement time information for measuring PRS. The measurement time information may be used to indicate (or configure) the measurement time window for measuring PRS, etc. It may also include a frequency hopping configuration (or frequency point configuration) for carrier phase measurement and / or time measurement, etc.

[0174] S1206: The UE and the PRU measure the PRS from the base station A and the PRS from the base station B respectively to obtain measurement results.

[0175] It can be understood that the UE (or PRU) can measure the PRS from base station A and the PRS from base station B based on the same frequency hopping configuration (or frequency configuration) or based on different frequency hopping configurations (or frequency configurations). If the PRS from base station A and the PRS from base station B are measured based on different frequency hopping configurations (or frequency configurations), the LMF network element can send the frequency hopping configurations (or frequency configurations) corresponding to different base stations to the UE (or PRU). For example: refer to Fig.13 In the PRS transmission configuration diagram shown in FIG. 1 , the shaded part represents PRS transmission. The time domain units for sending PRS by base station A and base station B are different, and may correspond to different frequency hopping configurations (or frequency point configurations), respectively.

[0176] S1207: The UE and PRU send measurement results to the LMF network element respectively. Correspondingly, the LMF network element receives the measurement results sent by the UE and PRU respectively.

[0177] Among them, the UE (or PRU) can send the measurement results of the corresponding base station A and the measurement results of the corresponding base station B to the LMF network element, and the measurement results may include carrier phase measurement results and / or time measurement results.

[0178] After the LMF network element receives the measurement results sent by the UE and the PRU respectively, it can determine the position of the UE based on one or more of the double-difference carrier phase positioning technology, the time-based positioning technology, etc. according to the measurement results sent by the UE and the PRU respectively.

[0179] For the first communication device (such as a RedCap UE) to receive the positioning reference signal through frequency hopping, the longer the duration of the frequency hopping, the larger the equivalent bandwidth, and the more accurate the time measurement result. However, for carrier phase measurement, the measurement is independent of the bandwidth size. Therefore, in some implementations, frequency hopping configurations can be sent separately for carrier phase measurement and time measurement, and the two sets of frequency hopping configurations are used for carrier phase measurement and time measurement respectively.

[0180] Exemplarily: The frequency hopping configuration from the positioning management device may include a first frequency hopping configuration and a second frequency hopping configuration. The positioning assistance device can measure the positioning reference signal from the second communication device according to the first frequency hopping configuration to obtain at least one carrier phase measurement result, and measure the positioning reference signal from the second communication device according to the second frequency hopping configuration to obtain a time measurement result.

[0181] In a possible implementation, since the carrier phase measurement is independent of the bandwidth size, the bandwidth (or equivalent bandwidth) corresponding to the first frequency hopping configuration can be less than or equal to the bandwidth (or equivalent bandwidth) corresponding to the second frequency hopping configuration to improve the measurement efficiency and reduce the measurement overhead. The bandwidth corresponding to the frequency hopping configuration can be the total bandwidth occupied by multiple frequency hops configured (or corresponding) by the frequency hopping configuration in the frequency domain. For example Figure 8 As shown, the RedCap UE receives the positioning reference signal through frequency hopping from time domain unit t1 to time domain unit t5. The bandwidth of each frequency domain unit is, for example, 20 MHz, then the total bandwidth occupied by multiple frequency hops in the frequency domain is 100 MHz, and the bandwidth (or equivalent bandwidth) corresponding to the frequency hopping configuration is 100 MHz.

[0182] Or rather, it can also be that the duration corresponding to the first frequency hopping configuration is less than or equal to the duration corresponding to the second frequency hopping configuration; and / or, the number of frequency hops corresponding to the first frequency hopping configuration is less than or equal to the number of frequency hops corresponding to the second frequency hopping configuration to improve the measurement efficiency and reduce the measurement overhead. The duration corresponding to the frequency hopping configuration can refer to the total duration of one or more time domain units where the frequency hopping configuration is configured (or occupied); or the duration from the start of the first frequency hop to the end of the last frequency hop among one or more frequency hops configured by the frequency hopping configuration; or the duration from the start of the first frequency hop to the start of the last frequency hop, etc.

[0183] As an example: Refer to Fig.14As shown, the horizontal direction represents the time domain and the vertical direction represents the frequency domain. Five frequency hoppings (i.e., 5 hops) may be included in the measurement time window. The frequency hopping configured by the second frequency hopping configuration may include a total of 5 frequency hoppings corresponding to the time domain unit t1-time domain unit t5, and the frequency hopping points of the 5 frequency hoppings are different; the frequency hopping configured by the first frequency hopping configuration may include a total of 2 frequency hoppings corresponding to the time domain unit 1 and the time domain unit 5. The first communication device (or positioning auxiliary device) may determine the carrier phase measurement result according to the 2 frequency hoppings configured by the first frequency hopping configuration, and determine the time measurement result according to the 5 frequency hoppings configured by the second frequency hopping configuration. That is, for the first frequency hopping configuration, 2 hops may be measured in the measurement time window, with a time interval of t5-t1, corresponding to the frequency hopping of the time domain unit t5 and the time domain unit t1; for the second frequency hopping configuration, 5 hops may be measured in the measurement time window, with a time interval of t2-t1, corresponding to the frequency hopping of the time domain unit t2, the time domain unit t3, the time domain unit t4, the time domain unit t5, and the time domain unit t1.

[0184] As an example: See Fig.15 As shown, the horizontal direction represents the time domain and the vertical direction represents the frequency domain. Five frequency hoppings (i.e., 5 hops) may be included in the measurement time window. The frequency hopping configured by the second frequency hopping configuration may include a total of 5 frequency hoppings corresponding to the time domain unit t1-time domain unit t5, and the frequency hopping points of the 5 frequency hoppings are different; the frequency hopping configured by the first frequency hopping configuration includes a total of 5 frequency hoppings corresponding to the time domain unit t1-time domain unit t5, and the frequency hopping points of the 5 frequency hoppings may be the same. The first communication device (or positioning auxiliary device) may determine the carrier phase measurement result according to the 5 frequency hoppings configured by the first frequency hopping configuration, and determine the time measurement result according to the 5 frequency hoppings configured by the second frequency hopping configuration.

[0185] It can be understood that the frequency hopping configured by the positioning assistance device according to the first frequency hopping configuration and the frequency hopping configured by the second frequency hopping configuration can be applied in one measurement time window or in different measurement time windows. For example, the frequency hopping configured by the first frequency hopping configuration is applied to measurement time window A, and the frequency hopping configured by the second frequency hopping configuration is applied to measurement time window B. If the frequency hopping configured by the first frequency hopping configuration and the frequency hopping configured by the second frequency hopping configuration are applied to the same measurement time window, the frequency hopping configured by the first frequency hopping configuration can be a subset of the frequency hopping configured by the second frequency hopping configuration. For example Fig.14 In the embodiment, the two hopping frequencies configured by the first frequency hopping configuration are subsets of the five hopping frequencies configured by the second frequency hopping configuration.

[0186] In one possible design, the capabilities of the first communication device include a maximum duration for which the first communication device supports carrier phase hopping, wherein the duration corresponding to the second hopping configuration is less than or equal to the maximum duration for which the first communication device supports carrier phase hopping, so as to avoid the duration corresponding to the hopping configuration exceeding a measurement time window configured for the first communication device.

[0187] For example: the positioning management device can configure a measurement time window for the first communication device according to the maximum duration of the carrier phase frequency hopping supported by the first communication device, and can indicate or configure the measurement time window to the first communication device through positioning assistance information, positioning request and other signaling, as well as the positioning assistance device that assists in positioning the first communication device. In addition, the duration corresponding to the first frequency hopping configuration and the duration corresponding to the second frequency hopping configuration sent to the first communication device (or positioning assistance device) are less than or equal to the maximum duration of the carrier phase frequency hopping supported by the first communication device, so as to avoid the duration corresponding to the frequency hopping configuration exceeding the measurement time window configured for the first communication device.

[0188] Fig.16 The following example illustrates the second downlink positioning process. Fig.16 As shown, the process includes:

[0189] S1601: The LMF network element obtains UE capabilities through the LTE positioning protocol Capability Transfer process.

[0190] Exemplary: The LMF network element can obtain the UE's positioning-related capabilities, PRS receiving capabilities (such as working bandwidth) and measurement capabilities through the LTE positioning protocol (LPP) Capability Transfer process, and can also include the maximum time that the RedCap UE supports carrier phase hopping.

[0191] S1602: The LMF network element sends information requests to base station A and base station B respectively, and accordingly, base station A and base station B receive the information requests respectively.

[0192] Optionally, the information request may be used to request to obtain attribute information of base station A (or base station B). Exemplarily, the attribute information may include, but is not limited to, base station identification (such as ID), cell information covered by the base station, location information (such as coordinates), or PRS configuration information.

[0193] S1603: Base station A and base station B send information responses to the LMF network element respectively. Correspondingly, the LMF network element receives information responses from base station A and base station B respectively.

[0194] Optionally, the information response includes attribute information of base station A (or base station B).

[0195] S1604: The LMF network element sends positioning assistance information to the UE and the PRU respectively, and correspondingly, the UE and the PRU respectively receive the positioning assistance information.

[0196] Exemplarily: the positioning assistance information may include at least one of the following: PRS configuration, location information of base station A, location information of base station B, an identifier of base station A or an identifier of base station B, etc.

[0197] S1605: The LMF network element sends positioning request information to the UE and the PRU respectively, and correspondingly, the UE and the PRU respectively receive the positioning request information.

[0198] Exemplary: The positioning request information can be used to request the UE (or PRU) to measure the PRS. The positioning request information can include measurement time information for measuring the PRS. The measurement time information can be used to indicate the measurement time window for measuring the PRS, etc. It can also include a first frequency hopping configuration for carrier phase measurement and a second frequency hopping configuration for time measurement.

[0199] S1606: The UE and the PRU measure the PRS from the base station A and the PRS from the base station B respectively, and obtain measurement results, wherein the measurement results include carrier phase measurement results and time measurement results.

[0200] S1607: The UE and PRU send measurement results to the LMF network element respectively. Correspondingly, the LMF network element receives the measurement results sent by the UE and PRU respectively.

[0201] It can be understood that the UE (or PRU) measures the PRS from base station A and the PRS from base station B, based on the first frequency hopping configuration and the second frequency hopping configuration which can be the same or different. If different LMF network elements can send the first frequency hopping configuration and the second frequency hopping configuration corresponding to different base stations to the UE (or PRU).

[0202] After the LMF network element receives the measurement results sent by the UE and the PRU respectively, it can determine the position of the UE based on one or more of the double-difference carrier phase positioning technology, the time-based positioning technology, etc. according to the measurement results sent by the UE and the PRU respectively.

[0203] The above positioning method mainly introduces the downlink positioning process in which the second communication device (such as a base station) sends a positioning reference signal, and the first communication device (or a positioning auxiliary device) measures the positioning reference signal from the second communication device; in some implementations, for the uplink positioning process in which the second communication device measures the positioning reference signal from the first communication device (or a positioning auxiliary device), the LMF network element may also send two sets of frequency hopping configurations to the second communication device, which are used for carrier phase measurement and time measurement respectively.

[0204] Fig.17 The second schematic diagram of the positioning method provided in the embodiment of the present application includes:

[0205] S1701: The positioning management device sends a third frequency hopping configuration and a fourth frequency hopping configuration to the second communication device, and correspondingly, the second communication device receives the third frequency hopping configuration and the fourth frequency hopping configuration.

[0206] S1702: The second communication device measures the positioning reference signal from the first communication device according to the third frequency hopping configuration to obtain a carrier phase measurement result; and measures the positioning reference signal from the first communication device according to the fourth frequency hopping configuration to obtain a time measurement result.

[0207] S1703: The second communication device sends the measurement result to the positioning management device, and correspondingly, the positioning management device receives the measurement result.

[0208] The measurement result includes the above-mentioned carrier phase measurement result and time measurement result, and the measurement result is used to locate the first communication device.

[0209] The longer the frequency hopping duration is, the larger the equivalent bandwidth is, and the more accurate the time measurement result is. However, for carrier phase measurement, the measurement is independent of the bandwidth size. Therefore, in some implementations, frequency hopping configurations can be sent separately for carrier phase measurement and time measurement, and two sets of frequency hopping configurations are used for carrier phase measurement and time measurement respectively.

[0210] Exemplarily: the positioning management device can send a third frequency hopping configuration and a fourth frequency hopping configuration to the second communication device, and the second communication device can measure the positioning reference signal from the first communication device (or the positioning assistance device) according to the third frequency hopping configuration to obtain at least one carrier phase measurement result, and measure the positioning reference signal from the first communication device (or the positioning assistance device) according to the fourth frequency hopping configuration to obtain a time measurement result.

[0211] In one possible implementation, since the carrier phase measurement is independent of the bandwidth size, the bandwidth (or equivalent bandwidth) corresponding to the third frequency hopping configuration can be less than or equal to the bandwidth (or equivalent bandwidth) corresponding to the fourth frequency hopping configuration to improve measurement efficiency and reduce measurement overhead.

[0212] In other words, the duration corresponding to the third frequency hopping configuration may be less than or equal to the duration corresponding to the fourth frequency hopping configuration; and / or the number of frequency hoppings corresponding to the third frequency hopping configuration may be less than or equal to the number of frequency hoppings corresponding to the fourth frequency hopping configuration, so as to improve measurement efficiency and reduce measurement overhead. The duration corresponding to the frequency hopping configuration may refer to the total duration of the time domain unit where one or more frequency hoppings configured by the frequency hopping configuration are located; or it may refer to the duration from the first frequency hopping to the end of the last frequency hopping in one or more frequency hoppings configured by the frequency hopping configuration; or it may refer to the duration from the first frequency hopping to the start of the last frequency hopping, etc.

[0213] As an example: See Fig.18 As shown, the horizontal direction represents the time domain and the vertical direction represents the frequency domain. Five frequency hoppings (i.e., 5 hops) may be included in the measurement time window. The frequency hopping configured by the fourth frequency hopping configuration may include a total of 5 frequency hoppings corresponding to the time domain unit t1-time domain unit t5, and the frequency hopping points of the 5 frequency hoppings are different; the frequency hopping configured by the third frequency hopping configuration may include a total of 2 frequency hoppings corresponding to the time domain unit 1 and the time domain unit 5. The second communication device ( Fig.18 Taking TRP as an example), the carrier phase measurement results (such as the carrier phase measurement results of frequency points f1 and f5) can be determined according to the two frequency hoppings configured by the third frequency hopping configuration, and the time measurement results can be determined according to the five frequency hoppings configured by the fourth frequency hopping configuration. That is to say, for the third frequency hopping configuration, two hops can be measured within the measurement time window, with a time interval of t5-t1, corresponding to the frequency hopping of time domain unit t5 and time domain unit t1; for the fourth frequency hopping configuration, five hops can be measured within the measurement time window, with a time interval of t2-t1, corresponding to the frequency hopping of time domain unit t2, time domain unit t3, time domain unit t4, time domain unit t5, and time domain unit t1.

[0214] It can be understood that the frequency hopping configured by the third frequency hopping configuration and the frequency hopping configured by the fourth frequency hopping configuration can be applied in one measurement time window or in different measurement time windows. For example, the frequency hopping configured by the third frequency hopping configuration can be applied in measurement time window A, and the frequency hopping configured by the fourth frequency hopping configuration can be applied in measurement time window B. If the frequency hopping configured by the third frequency hopping configuration and the frequency hopping configured by the fourth frequency hopping configuration are applied in the same measurement time window, the frequency hopping configured by the third frequency hopping configuration can be a subset of the frequency hopping configured by the fourth frequency hopping configuration. For example Fig.18 In the embodiment, the two hopping frequencies configured by the third frequency hopping configuration are a subset of the five hopping frequencies configured by the fourth frequency hopping configuration.

[0215] Combine the following Fig.19 The specific example shown above Fig.17 The positioning method shown is introduced in detail. In the following example, the positioning reference signal is a sounding reference signal (SRS), the first communication device is a UE, the second communication device is a serving base station (i.e., the base station to which the serving cell where the UE resides belongs, such as base station A), at least one neighboring base station (i.e., the base station to which the neighboring cell of the serving cell where the UE resides belongs, such as base station B), and the positioning management device is an LMF network element. Optionally, the second communication device may also be a TRP, such as the second communication device being a serving TRP and at least one neighboring TRP.

[0216] Fig.19 An example of an uplink positioning process is given. Fig.19 As shown, the process includes:

[0217] S1901: The LMF network element sends a configuration request to base station A, and accordingly, base station A receives the configuration request.

[0218] The configuration request may be used to request base station A to allocate SRS configuration information to UE and PRU. Exemplarily, the SRS configuration information may include but is not limited to time domain resources, frequency domain resources, signal transmission period or SRS identification information.

[0219] Optionally, the LMF network element can send a configuration request to base station A through the NR positioning protocol (new radio positioning protocolannex, NRPPa) or other forms of positioning protocols.

[0220] S1902: Base station A determines available SRSs, and sends available SRS configuration information to the UE and PRU. Correspondingly, the UE and PRU receive the SRS configuration information.

[0221] Optionally, base station A may determine some idle or available SRSs according to the resource occupancy of the SRSs.

[0222] S1903: Base station A sends SRS configuration information to the LMF network element, and correspondingly, the LMF network element receives the SRS configuration information.

[0223] Optionally, base station A can send the SRS configuration information of UE and PRU to the LMF network element through the NR positioning protocol.

[0224] S1904: The LMF network element sends SRS configuration information to base station A and base station B respectively, and accordingly, base station A and base station B receive the SRS configuration information respectively.

[0225] Optionally, the LMF network element may select at least one base station whose distance from the UE meets the set conditions from multiple base stations to participate in the positioning of the terminal device, such as base station A and base station B, based on the location information of the UE and the location information of multiple base stations stored. Afterwards, the LMF network element may send SRS configuration information to base stations A and B participating in the positioning through the NR positioning protocol. The SRS configuration information is used to assist base station A and base station B in measuring SRS, respectively. Optionally, the set condition includes one of the following: the distance between the base station and the UE is less than or equal to a set threshold, or the distances of multiple base stations to the UE are arranged in ascending order, and the base stations are ranked in the first m.

[0226] S1905: The LMF network element sends measurement requests to base station A and base station B respectively, and accordingly, base station A and base station B receive the measurement requests respectively.

[0227] Optionally, the first request may include measurement time information for measuring SRS, the measurement time information may include a measurement time window for indicating measuring SRS, etc., and may also include a third frequency hopping configuration for carrier phase measurement and a fourth frequency hopping configuration for time measurement.

[0228] S1906: Base station A and base station B measure the SRS from the UE and the PRU respectively to obtain measurement results, wherein the measurement results include carrier phase measurement results and time measurement results.

[0229] It can be understood that base station A (or base station B) measures the SRS from the UE and the SRS from the PRU, and the third frequency hopping configuration and the fourth frequency hopping configuration based on them can be the same or different. If different LMF network elements can send the third frequency hopping configuration and the fourth frequency hopping configuration corresponding to the UE and the third frequency hopping configuration and the fourth frequency hopping configuration corresponding to the PRU to base station A (or base station B).

[0230] S1907: Base station A and base station B send measurement results to the LMF network element respectively. Correspondingly, the LMF network element receives the measurement results sent by base station A and base station B respectively.

[0231] For example, base station A and base station B can report the carrier phase and time measurement results of UE and PRU according to the measurement time information. After receiving the measurement results, the LMF network element can determine the position of the UE based on one or more of the positioning technology based on double difference carrier phase and the positioning technology based on time according to the measurement results sent by base station A and base station B respectively.

[0232] The communication device provided in the embodiment of the present application is described below. Fig. 20 , Fig. 20 This is a schematic diagram of the structure of the communication device of the embodiment of the present application. The communication device may include units or modules corresponding to all or part of the steps in the above method embodiment, and may be used to execute the steps executed by the positioning management device or the positioning auxiliary device or the second communication device in the above embodiment. For details, please refer to the relevant introduction in the above method embodiment.

[0234] Optionally, the transceiver unit 2020 may include a sending unit and / or a receiving unit. The sending unit is used to perform the sending-related operations of the positioning management device, the positioning auxiliary device, or the second communication device side in the above method embodiment; the receiving unit is used to perform the receiving-related operations of the positioning management device, the positioning auxiliary device, or the second communication device side in the above method embodiment.

[0235] It should be noted that the communication device 2000 may include a sending unit but not a receiving unit. Alternatively, the communication device 2000 may include a receiving unit but not a sending unit. This may be determined by whether the above solution executed by the communication device 2000 includes a sending action and a receiving action.
