[0001] Cross-reference to Related Applications

[0002] This application claims priority to the Chinese Patent Application No. 202411245081.1, filed on September 5, 2024, entitled “Signal Measurement Result Transmission Method, Apparatus, Storage Medium and Program Product”, the entire contents of which are incorporated herein by reference. TECHNICAL FIELD

[0003] The present application relates to the field of communication, and in particular to a signal measurement result transmission method, apparatus, storage medium and computer program product. BACKGROUND

[0004] With the rapid development of communication technology, high-precision positioning has gradually been determined as an important research project in the 3rd generation partnership project (3GPP) 5th generation mobile communication technology (5G). The scenarios of new radio (NR) positioning mainly include: enhanced mobile broadband (eMBB) outdoor, eMBB indoor, ultra-reliable and low latency communications (URLLC), and massive machine type of communication (mMTC) / internet of things (IOT). The positioning technology also requires high security, scalability, high availability, and high precision in high-speed applications.

[0005] In the 3GPP standard, multiple positioning technologies such as time of arrival (TOA), time difference of arrival (TDOA), and round trip time (RTT) are supported. For example, the receiving end measures the arrival time of the signal sent by the sending end, and then determines the distance between the sending end and the receiving end based on the arrival time, and determines the position of the target to be positioned according to the distance. How to further improve the positioning accuracy has become a problem to be solved at present. SUMMARY

[0006] The embodiments of the present application provide a signal measurement result transmission method and device, a storage medium and a computer program product, to transmit measurement results and information of antennas corresponding to the measurement results, so as to assist positioning and improve positioning accuracy.

[0007] In a first aspect, the embodiments of the present application provide a signal measurement result transmission method, which can be applied to a first communication device. The first communication device can be a network device or a unit, module or chip (or chip system, or circuit) in the network device. The network device can include an access network device, a backhaul module of a core network, a core network element, or a module (such as a distributed unit (DU), a centralized unit (CU) or a RAN intelligent controller (RIC)) in an open RAN (O-RAN). RAN is the abbreviation of radio access network.

[0008] The first communication device receives a first signal through N antennas, where N is a positive integer. The first communication device transmits measurement result indication information and first information. The measurement result indication information is determined according to N first measurement results. The N first measurement results are obtained according to the first signal. One of the N first measurement results is obtained by measuring the first signal by one of the N antennas. The first information is used to indicate information of an antenna corresponding to the measurement result indication information.

[0009] Since the first communication device transmits the first information, the positioning management device can more accurately determine the position of the second communication device in combination with the first information and the measurement result indication information, thereby improving the positioning accuracy. For example, the positioning management device can calculate the distance between the antenna that measures the first signal (rather than the position of the entire antenna panel of the first communication device) and the second communication device in combination with the position of the antenna and the measurement result corresponding to the antenna, so that the distance value is more accurate, and the positioning accuracy can be improved based on the more accurate distance value.

[0010] In a possible implementation, the information of the antenna corresponding to the measurement result indication information comprises: position information of the antenna corresponding to the measurement result indication information in the N antennas; and / or information of a relationship between the measurement result indicated by the measurement result indication information and the N first measurement results. The information of the relationship between the measurement result indicated by the measurement result indication information and the N first measurement results can implicitly indicate the position information of the antenna corresponding to the measurement result indication information in the N antennas. For example, the information of the relationship between the measurement result indicated by the measurement result indication information and the N first measurement results comprises: information that the measurement result indicated by the measurement result indication information is an average value and / or a median of the N first measurement results. The positioning management apparatus can determine a relatively central position of the antenna corresponding to the measurement result indication information in the N antennas. These information can assist the positioning management apparatus to determine the position of the antenna, and then the positioning management apparatus can more accurately calculate the distance between the second communication apparatus and the antenna based on the position of the antenna and the measurement result indication information, so that the positioning accuracy can be improved based on the distance.

[0011] In a possible implementation, the position information of the antenna corresponding to the measurement result indication information in the N antennas comprises at least one of the following: an index of the antenna corresponding to the measurement result indication information; coordinate information of the antenna corresponding to the measurement result indication information; or information of a relative position relationship between the antenna corresponding to the measurement result indication information and a reference position. The reference position may, for example, be a position of an antenna reference point (ARP). These manners can assist the positioning management apparatus to determine the position of the antenna, and can also save signaling overhead.

[0012] In a possible implementation, the measurement result indication information indicates at least one measurement result. The measurement result indicated by the measurement result indication information comprises: a measurement result determined according to the at least one first measurement result and / or the first measurement result. The measurement result indication information sent by the first communication apparatus can comprise the first measurement result (for example, a median, a minimum value or a maximum value of the plurality of first measurement results, etc.), or comprise information used to indicate the first measurement result. Alternatively, the measurement result indication information sent by the first communication apparatus can comprise some values calculated according to the first measurement result, for example, an average value, a weighted average value, etc. of the plurality of first measurement results. In this way, the flexibility of the scheme can be improved.

[0013] In a possible implementation, when the measurement result indication information indicates a plurality of measurement results, the measurement result indication information comprises: at least one measurement result, and information of a value rule of the plurality of measurement results. In this way, signaling overhead can be saved.

[0014] In a possible implementation, the information of the value rule of the plurality of measurement results comprises information of a variation amount between two measurement results in the plurality of measurement results.

[0015] In a possible implementation, one of the N antennas comprises one physical antenna element or one antenna port.

[0016] In a second aspect, an embodiment of the present application provides a signal measurement result transmission method, which can be applied to a positioning management apparatus.

The positioning management device can also comprise a network device (for example, an access network device) or a terminal device with a positioning function. The network device can comprise an access network device, a backhaul module of a core network, a core network element, a module (for example, a DU, a CU or a RIC) in an O-RAN, and the like.

[0017] The positioning management apparatus receives measurement result indication information and first information. The measurement result indication information is determined according to N first measurement results, the N first measurement results are obtained according to a first signal from a second communication apparatus, one of the N first measurement results is obtained by one of N antennas of a first communication apparatus measuring the first signal, N is a positive integer, and the first information is used to indicate information of an antenna corresponding to the measurement result indication information. The positioning management apparatus determines position information of the second communication apparatus according to the measurement result indication information and the first information.

[0018] Since the positioning management apparatus obtains the first information, the positioning management apparatus can more accurately determine the position of the second communication apparatus in combination with the first information and the measurement result indication information, thereby improving the positioning accuracy. For example, the positioning management apparatus can calculate the distance between the antenna measuring the first signal and the second communication apparatus in combination with the position of the antenna (rather than the position of the entire antenna panel of the first communication apparatus) and the measurement result corresponding to the antenna, so that the distance value is relatively accurate, and the positioning accuracy can be improved based on the relatively accurate distance value.

[0019] The measurement result indication information and the N antennas, and other contents and beneficial effects can be referred to the foregoing description of the first aspect and the possible implementation of the first aspect, and will not be repeated here.

[0020] In a third aspect, an embodiment of the present application provides a signal measurement result transmission method, which can be applied to a second communication device. The second communication device can be a terminal device or a unit, module or chip (or chip system, or circuit) inside the terminal device.

[0021] The second communication device receives M second signals. M is a positive integer, the M second signals are respectively transmitted by the first communication device through M antenna ports, and one of the M second signals is transmitted through one of the M antenna ports.

[0022] Since the second communication device transmits the second information, the positioning management device can more accurately determine the position of the second communication device in combination with the second information and the measurement result indication information, thereby improving the positioning accuracy. For example, the positioning management device can calculate the distance between the antenna that measures the second signal (rather than the position of the entire antenna panel of the first communication device) and the second communication device in combination with the position of the antenna and the measurement result corresponding to the antenna, so that the distance value is more accurate, and the positioning accuracy can be improved based on the more accurate distance value.

[0023] In a possible implementation, the second communication device receives information indicating the antenna port corresponding to the second signal of the M second signals. In this way, the second communication device can determine the information of the antenna port corresponding to the measurement result, and then indicate to the positioning management device, so that the positioning management device can perform more accurate positioning according to the information of the antenna port corresponding to the measurement result.

[0024] In a possible implementation, the information about the antenna port corresponding to the measurement result indication information comprises: position information of the antenna port corresponding to the measurement result indication information in the M antenna ports; and / or information about the relationship between the measurement result indicated by the measurement result indication information and the M second measurement results. The information about the relationship between the measurement result indicated by the measurement result indication information and the M second measurement results can implicitly indicate the position information of the antenna port corresponding to the measurement result indication information in the M antenna ports. For example, the information about the relationship between the measurement result indicated by the measurement result indication information and the M second measurement results comprises information that the measurement result indicated by the measurement result indication information is the average value and / or the median of the M second measurement results. The positioning management apparatus can determine a relatively central position of the antenna port corresponding to the measurement result indication information in the M antenna ports. These information can assist the positioning management apparatus to determine the position of the antenna port, and then the positioning management apparatus can more accurately calculate the distance between the second communication apparatus and the antenna port based on the position of the antenna port and the measurement result indication information, so as to improve the positioning accuracy based on the distance.

[0025] In a possible implementation, the position information of the antenna port corresponding to the measurement result indication information in the M antenna ports comprises at least one of the following: an index of the antenna port corresponding to the measurement result indication information; coordinate information of the antenna port corresponding to the measurement result indication information; or information about the relative position relationship between the antenna port corresponding to the measurement result indication information and a reference position. The reference position may, for example, be the position of the ARP. These manners can assist the positioning management apparatus to determine the position of the antenna port, and can also save signaling overhead.

[0026] In a possible implementation, the measurement result indication information indicates at least one measurement result. The measurement result indicated by the measurement result indication information comprises a measurement result determined according to at least one second measurement result and / or the second measurement result. The measurement result indication information sent by the second communication apparatus can comprise the second measurement result, or comprise information for indicating the second measurement result. Alternatively, the measurement result indication information sent by the second communication apparatus can comprise some values calculated according to the second measurement result, for example, the average value, the weighted average value or the median of the plurality of second measurement results. In this way, the flexibility of the scheme can be improved.

[0027] In a possible implementation, when the measurement result indication information indicates a plurality of measurement results, the measurement result indication information comprises: at least one measurement result, and information about the value rule of the plurality of measurement results. In this way, signaling overhead can be saved.

[0028] In a possible implementation, the information about the value rule of the plurality of measurement results comprises: information about the variation between two measurement results in the plurality of measurement results.

[0029] In a possible implementation, the second communication device sends information indicating that it has the capability of measuring signals from multiple antenna ports. In this way, the positioning management device can know that the second communication device has the capability of measuring signals from multiple antenna ports. In this way, the positioning management device can send the configuration of the second signal transmitted through multiple antenna ports to the second communication device, so that the second communication device measures the second signal of multiple antenna ports based on its own capability.

[0030] In another possible implementation, the second communication device can also send information indicating the number of antenna ports (for example, 2, 4, 8, or other positive integers greater than 1) supported (for example, the maximum supported) by the second communication device. In this way, the positioning management device can send the configuration information of the second signal based on the capability of the second communication device, so as not to configure the configuration of the second signal beyond the capability of the second communication device.

[0031] In a possible implementation, one of the M second antenna ports includes one or more physical antenna elements.

[0032] In a fourth aspect, an embodiment of the present application provides a signal measurement result transmission method, which can be applied to a positioning management device.

The positioning management device can also include a network device (such as an access network device) or a terminal device with positioning function. The network device can include an access network device, a backhaul module of a core network, a core network element, a module (such as a DU, a CU or a RIC) in an O-RAN, etc.

The positioning management device determines the position information of the second communication device according to the measurement result indication information and the second information.

[0034] Since the positioning management apparatus acquires the second information, the positioning management apparatus can determine the position of the second communication apparatus more accurately in combination with the second information and the measurement result indication information, thereby improving the positioning accuracy. For example, the positioning management apparatus can calculate the distance between the antenna and the second communication apparatus in combination with the position of the antenna (rather than the position of the entire antenna panel of the first communication apparatus) for measuring the second signal and the measurement result corresponding to the antenna, so that the distance value is more accurate, and the positioning accuracy can be improved based on the more accurate distance value.

[0072] The following first introduces the terms and terminologies involved in the embodiments of the present application.

[0073] (1) Signal for positioning.

[0074] The first signal and the second signal involved in the embodiments of the present application can be understood as signals that can be used for positioning. The first signal and the second signal in the embodiments of the present application can also be referred to as positioning signals. In order to distinguish, for example, the first signal can be referred to as the first positioning signal, the second signal can be referred to as the second positioning signal, and the like.

[0075] One or more of the first signal and the second signal in the embodiments of the present application can be a positioning reference signal (PRS), can also be a sounding reference signal (SRS), can also be one or more of a channel state information reference signal (CSI-RS), a demodulation reference signal (DMRS), a phase-tracking reference signal (PTRS), a cell reference signal (CRS), a synchronization signal / physical broadcast channel block (SSB), and a sidelink sounding reference signal (SL-SRS).

[0076] (2) Concept of one signal.

[0077] For example, one signal can refer to a signal corresponding to one resource identification (resource ID). Taking the second signal as an example, for example, two second signals refer to signals corresponding to two resource identifications (resource IDs). The first communication device can configure configuration information of the second signal, and the configuration information of the second signal can include a resource identification of the second signal, and can also include a resource (such as a time domain resource and / or a frequency domain resource) of the second signal. The resource identifications corresponding to the two second signals are different.

[0078] (3) ARP.

[0079] The ARP can be understood as a physical point of an antenna calibration reference on an antenna panel corresponding to the ARP, and can be used to determine the antenna position. The ARP can be a point on the antenna panel, or a point outside the antenna panel, such as the ARP can be a center point of the antenna panel, or a position where an antenna array element on the antenna panel is located, and the like. For example, the ARP can select the intersection of the bottom of the receiver antenna and the antenna central axis as the reference point (as shown in FIG. 1). The consistent antenna reference point can be understood as the consistent antenna position, and generally one antenna array surface reports one antenna reference point.

[0080] (4) Antenna and antenna port.

[0081] The antenna (antenna, ANT) can include an antenna on a device, or can include an antenna port connected to a radio frequency front end. For example, one antenna in an embodiment of the present application can include one antenna array element, or can include one antenna port.

[0082] The antenna array element can also be referred to as a physical antenna array, a physical antenna array, a physical antenna array element, a physical antenna, a physical antenna port, a physical antenna interface, a physical antenna transmitting port, or a physical antenna receiving port, and the like.

[0083] The antenna port (antenna port) can be understood as a logical port. The antenna port (antenna port) can include one or more antenna array elements. The antenna port can also be referred to as a logical antenna, a logical antenna port, a logical antenna interface, a logical antenna transmitting port, or a logical antenna receiving port. The antenna port can be used to represent the wireless channel state. The channel carried by a certain antenna port on one symbol can be inferred from the signal carried by the antenna port on another symbol. For example, the terminal device can measure the channel in terms of the antenna port, for example, the base station transmits reference signals through a plurality of antenna ports, and the terminal device can estimate a plurality of channels.

[0084] Figure 2A illustrates an exemplary architecture of a communication system 1000 to which embodiments of the present application can be applied. As shown in Figure 2A, the communication system includes a radio access network 100 and a core network 200. Optionally, the communication system 1000 can further include an Internet 300. The radio access network 100 can include at least one radio access network device (e.g., 110a and 110b in Figure 2A) and at least one terminal device (e.g., 120a-120j in Figure 2A). The terminal devices are connected to the radio access network devices by wireless means, and the radio access network devices are connected to the core network by wireless or wired means. The core network devices and the radio access network devices can be independent and different physical devices, or can be integrated into the same physical device with the functions of the core network devices and the logical functions of the radio access network devices, or can be a physical device integrated with part of the functions of the core network devices and part of the functions of the radio access network devices. The terminal devices and the terminal devices, and the radio access network devices and the radio access network devices can be connected to each other by wired or wireless means. Figure 2A is only a schematic diagram, and the communication system can further include other network devices, such as wireless relay devices and wireless backhaul devices, which are not shown in Figure 2A.

[0085] The network device involved in the embodiments of the present application, for example, includes a radio access network (RAN) device. The radio access network device can be a base station, an evolved NodeB (eNodeB or eNB for short), a transmission reception point (TRP), a transmission point (TP), a base station in a 5th generation (5G) mobile communication system, a base station in a future mobile communication system, an access node in a WiFi system, etc.; it can also be a module or unit that completes part of the functions of a base station, for example, it can be a central unit (CU), or a distributed unit (DU), or a radio unit (RU). The CU here completes the functions of the radio resource control protocol and the packet data convergence protocol (PDCP) of the base station, and can also complete the function of the service data adaptation protocol (SDAP); the DU completes the functions of the radio link control layer and the medium access control (MAC) layer of the base station, and can also complete part of the physical layer or the entire physical layer. The specific description of the above-mentioned various protocol layers can refer to the relevant technical specifications of the 3rd generation partnership project (3GPP). The CU and the DU can be separately arranged, or can also be included in the same network element, such as a baseband unit (BBU). The RU can be included in a radio frequency device or a radio frequency unit, such as a remote radio unit (RRU), an active antenna processing unit (AAU), or a remote radio head (RRH). In different systems, the CU, DU or RU can also have different names, but those skilled in the art can understand their meanings.For example, in an open radio access network (ORAN) system, the CU can also be referred to as an open central unit (O-CU), the DU can also be referred to as an open distributed unit (O-DU), and the RU can also be referred to as an open radio unit (O-RU). Any of the CU, the central unit control plane (CU-CP), the central unit user plane (CU-UP), or the RU in this application can be implemented by a software module, a hardware module, or a combination of a software module and a hardware module.

Of course, 110a and 120i can also communicate through an interface protocol between base stations and base stations, and in this case, 120i is also a base station relative to 110a. Therefore, the base station and the terminal device can be collectively referred to as a communication device, 110a and 110b in FIG. 2A can be referred to as a communication device with a base station function, and 120a-120j in FIG. 2A can be referred to as a communication device with a terminal device function.

[0097] The SMO functions like a network management. The Non-RT RIC can be used to implement non-real-time intelligent management of RAN functions, for example, can implement an artificial intelligence (AI) / machine learning (ML) workflow including model training and model updating, and can guide applications / functions in the Near-RT RIC based on a policy. The Non-RT RIC can be located in the SMO module, and can implement monitoring, configuration, management and control of wireless resources of at least one of a plurality of O-CU-CPs, O-CU-UPs, DUs or O-eNBs. The Near-RT RIC can be used to implement near-real-time intelligent management of the RAN, for example, can implement near-real-time control and optimization of modules and resources of the O-RAN through data collection and related operations on the E2 interface.

[0098] The O-CU, for example, can implement radio resource control (RRC) layer, packet data convergence protocol (PDCP) layer, and service data adaptation protocol (SDAP) layer and other control functions in the 3GPP standards. The O-CU-CP can be similar to the CU-CP in the NR system, for implementing the functions of the RRC layer, and the control plane functions of the PDCP layer. It can belong to the O-CU. The O-CU-UP can be for implementing the functions of the SDAP layer, and the user plane functions of the PDCP layer, and can belong to the O-CU. Based on the low-layer function split, the O-DU can be for implementing the radio link control (RLC) layer, the media access control (MAC) layer, and the higher physical layer (Higher PHY) in the 3GPP standards. The functions of the higher physical layer include one or more of the following: forward error correction (FEC) encoding / decoding, scrambling / descrambling, or modulation / demodulation. Based on the low-layer function split, the O-RU can be for implementing the lower physical layer (Lower PHY) functions and the radio frequency functions in the 3GPP standards. The functions of the lower physical layer include one or more of the following: fast fourier transform (FFT) transform / inverse fast fourier transformation (iFFT) transform, digital beamforming, or extraction and filtering of the physical random access channel (PRACH), etc. Similar to the transmission reception point (TRP) or the remote radio head (RRH) in the 3GPP, but including the low physical layer functions, such as FFT / iFFT or extraction of the PRACH. The O-Cloud can be a cloud computing platform, including physical infrastructure nodes, for hosting O-RAN functions, such as RIC, O-DU, etc.; supporting software components (such as operating systems, virtual machine monitors, container runtimes), management and orchestration functions.

[0099] As shown in FIG. 2B, the interfaces defined by 3GPP include, for example, El, Fl (e.g., Fl-c, Fl-u), NG (e.g., NG-c, NG-u), Xn (e.g., Xn-c, Xn-u), X2 (e.g., X2-c, X2-u). For example, the O-RAN communication system also includes some interfaces, such as Ol, O2, E2, Al, Open-front hual (FH) (e.g., Open-FH control (M)-plane, for example, Open-FH control, user and synchronization (CUS)-plane), and the like. The names of the interfaces and the connection modes of the various units shown in FIG. 2B are examples, and in actual applications, the O-RAN system can include more or fewer interfaces, or include more or fewer units. Other contents of FIG. 2B can also be referred to the related description of the foregoing FIG. 2A, and will not be described again.

[0100] FIG. 2C exemplarily shows a communication system architecture diagram to which embodiments of the present application are applicable, which is exemplarily shown by taking the positioning architecture in LTE and NR Rel-16 as an example. As shown in FIG. 2C, the network elements / modules involved mainly include three parts of a next generation radio access network (NG RAN), a terminal device and a core network.

[0101] The core network includes a location management function (LMF), an access and mobility management function (AMF), a service location protocol (SLP), an evolved serving mobile location center (E-SMLC), and the like. The positioning server, i.e., the location management function (LMF), is connected to the AMF, and the LMF and the AMF are connected through an NLs interface. The UE communicates with a serving base station through a Uu link; the ng-eNB is a base station of LTE, and the gNB is a base station of NR, and the base stations communicate with each other through an Xn interface; the base station and the AMF communicate through an NG-C interface, and the AMF (Access and Mobility Management Function) is equivalent to a router for communication between the gNB and the LMF; the LMF implements location estimation of the UE, and the AMF and the LMF communicate through an NLs interface. The LMF is responsible for supporting different types of location services related to terminal devices, including positioning of terminal devices and delivery of assistance data to terminal devices. The LMF can perform positioning calculation on the terminal device according to the measurement results of other network elements. The AMF can receive a location service request related to the terminal device from a 5th generation core network location service (5GC LCS) entity, or the AMF itself can also initiate some location services on behalf of a specific terminal device, and forward the location service request to the LMF. After obtaining the location information returned by the terminal device, the relevant location information is returned to the 5GC LCS entity.

[0102] The NG RAN can include a next generation node B (gNB), a next generation evolved node B (ng-eNB), and the like. The gNB and the ng-eNB are connected through an Xn interface, and the LMF is connected to the ng-eNB / gNB through an NG-C interface.

[0103] One or more network devices on the NG RAN side configure resources for sending a reference signal, and send the reference signal to the terminal device, the terminal device measures the reference signal and the like downlink signal, and feeds back the measurement result to the LMF to support positioning. It should be understood that the reference signal for positioning can also be referred to as a positioning reference signal. For example, the positioning reference signal can be a PRS, a common reference signal (CRS), a channel state information (CSI)-RS, and the like. In one possible implementation, the PRS resource can be configured at the cell level, that is, the PRS resource is configured for each cell. When the terminal device re-establishes the RRC connection with the target cell, the base station of the target cell can configure the PRS resource for the target cell, and the terminal device acquires the PRS resource configured for the target cell to receive and measure the PRS on the PRS resource.

[0104] The communication method provided by the embodiments of the present application can be applied to various communication systems, for example: LTE system, 5G system such as NR, and future communication system (such as 6th generation mobile communication technology (6G)) system and the like. Of course, the technical solutions of the embodiments of the present application can also be applied to other communication systems, as long as the communication system has the positioning demand for the terminal device. In addition, the communication system can also be applicable to future-oriented communication technology, and the system described in the embodiments of the present application is to more clearly illustrate the technical solutions of the embodiments of the present application, and does not constitute a limitation on the technical solutions provided by the embodiments of the present application. Those skilled in the art can know that, with the evolution of network architecture, the technical solutions provided by the embodiments of the present application are also applicable to similar technical problems.

[0105] FIG. 2D shows a network architecture of another communication system to which the embodiments of the present application are applicable, which includes a core network, an NG-RAN and a terminal device. The core network includes LMF, AMF, secure user plane location (SUPL) location platform (SLP) and enhanced serving mobile location centre (E-SMLC) and the like network element / module, the NG RAN includes gNB, ng-eNB and the like network element / module, wherein the specific functions of LMF, AMF, SLP, E-SMLC, gNB and ng-eNB and the like network element / module, the connection relationship between each network element / module can refer to the introduction of the related part of FIG. 2C above, which will not be repeated here.

[0106] Different from Fig. 2C, in the network architecture shown in Fig. 2D, the LMC is added in the NG-RAN, and the LMC is specifically deployed inside the base station, such as being deployed in the gNB or being deployed in the ng-ENB. In this network architecture, the LMC is a function inside the base station, and thus a new interface does not need to be introduced. The LMC can assume part of the functions of the LMF, and in this architecture, the gNB can not report the measurement results of the signals used for positioning to the LMF of the core network, thereby saving signaling overhead and reducing positioning latency.

[0107] Fig. 2E shows another network architecture of a communication system to which embodiments of the present application are applicable. As shown in Fig. 2E, the communication system also includes a core network, an NG-RAN, and a terminal device. Different from Fig. 2D, in the network architecture shown in Fig. 2E, the LMC is a separate logical node in the NG-RAN and is connected to the base station through a new interface, for example, in Fig. 2E, the LMC is connected to the gNB-CU through the interface Itf.

[0108] Fig. 2F shows another network architecture of a communication system to which embodiments of the present application are applicable. As shown in Fig. 2F, the communication system also includes a core network, an NG-RAN, and a terminal device. Different from Fig. 2E, in the network architecture shown in Fig. 2F, the LMC can be connected to multiple base stations through the new interface. Fig. 2F takes an example in which the LMC is connected to two base stations, but in a specific implementation, the LMC can also be connected to more base stations.

[0109] It should be understood that the above Figs. 2C, 2D, 2E, and 2F are several exemplary descriptions of the communication system to which embodiments of the present application are applicable, and do not specifically limit the types, numbers, and connection manners of the network elements included in the communication system to which the present application is applicable. The network elements / modules shown in dashed lines in Figs. 2C, 2D, 2E, and 2F are not indispensable, and are optional, for example, the E-SMLC or the SLP is not indispensable; or the network elements / modules shown in dashed lines are another form of existence, for example, the gNB or the ng-eNB is also called a transmission reception point (TRP) in some embodiments, and the terminal device is called a SUPL enabled terminal (SET) in some embodiments, where SUPL is an abbreviation of secure user plane location (SUPL).

[0110] FIG. 3 illustrates a schematic diagram of a communication system architecture. FIG. 3 illustrates an example in which the second communication device sends a first signal to the first communication device. As shown in FIG. 3, the first communication device can include P*Q antennas. One antenna can be an antenna element or an antenna port. FIG. 3 illustrates an example in which one antenna is an antenna element. In FIG. 3, each antenna can be identified by a coordinate value. For example, the antenna identified as (0, 0) in FIG. 3 can represent an antenna with a coordinate of (0, 0), the antenna identified as (P-1, 0) can represent an antenna with a coordinate of (P-1, 0), and so on. Other details are similar and will not be repeated.

[0111] For example, the first communication device measures the first signal through all antennas (i.e., P*Q antennas) to obtain one measurement result. In this example, the measurement result is a TOA. The value of the one TOA is used to locate the second communication device. In this scheme, the TOAs of the first signal arriving at different antennas of the first communication device are assumed to be the same. One TOA value is estimated based on the first signal received by multiple antennas, and then the second communication device is located based on the one TOA value. However, there is a distance between different antennas of the first communication device (for example, in some scenarios, the antenna array of the first communication device is large, and the distance between different antennas is also large). This scheme ignores the distance, and the distances between different antennas of the first communication device and the second communication device should not be considered the same. This scheme results in low positioning accuracy.

[0112] In combination with FIG. 3, as shown in FIG. 3, the difference Δdis1 between the distance between the antenna with a coordinate of (0, 0) and the second communication device and the distance between the antenna with a coordinate of (P-1, 0) and the second communication device satisfies the following formula (1):

[0113] In formula (1), d1 is the distance between adjacent antennas in the vertical direction, k1 is the number of antennas between the antenna with a coordinate of (0, 0) and the antenna with a coordinate of (P-1, 0), θ1 is the angle between the second signal and the first line, and the first line is the line between the antenna with a coordinate of (0, 0) and the antenna with a coordinate of (P-1, 0). In this formula, the antenna with a coordinate of (0, 0) and the antenna with a coordinate of (P-1, 0) are taken as an example, and the calculation of the distance between other antennas is similar and will not be repeated.

[0114] It can be seen from formula (1) that the propagation path difference of the first signals corresponding to different antennas is large (for example, the path difference can be proportional to the number of antennas spaced apart between the antennas), and the TOA values corresponding to the signals received by different antennas can be large. As shown in FIG. 3, when the antenna array is large, for example, there are vertical dimension 96 antennas in the antenna array, the TOA value corresponding to the antenna with coordinates (0, 0) is 75.84 nanoseconds (ns), and the TOA of the antenna with coordinates (P-1, 0) is 80.28 ns. The TOA measured by the two antennas can differ by 4.44 ns. For positioning, it cannot be approximated that the TOAs of all antennas on the entire antenna array are consistent, and if the TOAs of all antennas on the entire antenna array are still considered consistent, the measured TOA will be a complex coupling of different TOAs of multiple antennas, which will in turn cause the positioning accuracy to decrease.

[0115] Based on the above problems, the present application provides a scheme, in which the positioning device can obtain measurement result information and can also obtain information of an antenna corresponding to the measurement result information, so that the antenna information and the measurement result information can be combined for positioning, thereby improving the positioning accuracy.

[0116] The beneficial effects of the scheme provided by the embodiments of the present application will be introduced in combination with FIG. 3.

[0117] For example, the first communication device obtains a measurement result, for example, a TOA#10, after receiving the first signal through N antennas. The TOA#10 is considered as the TOA value of all antennas, and the TOA values of all antennas are equal. This will cause the TOA#10 to be an inaccurate value. If the distance between the second communication device and the first communication device is calculated based on the position of the entire antenna panel (for example, the center position of the entire antenna panel) and the TOA#10, since the TOA#10 is inaccurate, and the scheme does not also base on the information (for example, the position) of the antenna corresponding to the measurement result, the distance value will also be inaccurate, which in turn causes the positioning accuracy of the second communication device to be low.

[0118] In the scheme provided in the embodiments of the present application, the first communication device can obtain one TOA by measuring the first signal through one of the N antennas. The N antennas correspond to N TOAs, and the scheme can more accurately calculate the value of the TOA corresponding to each antenna. If the first communication device transmits the average value of the N TOAs, the average value of the TOAs can also more accurately reflect the value of the TOA corresponding to the center position of the antenna panel. If the first communication device transmits TOA#11, and TOA#11 is the TOA corresponding to the antenna at coordinate (0, 0), the positioning management device can more accurately calculate the distance between the second communication device and the antenna at coordinate (0, 0), and can more accurately calculate the position of the second communication device according to the distance. As can be seen, in the calculation, the distance between each TOA corresponding antenna and the second communication device can be more accurately calculated, so that the second communication device can be more accurately positioned.

[0119] Based on the embodiments shown in FIGS. 1, 2A, 2B, 2C, 2D, 2E, 2F and 3 and the above-mentioned other contents, FIG. 4 exemplarily shows a flow diagram of a signal measurement result transmission method provided in an embodiment of the present application. The embodiment shown in FIG. 4 is introduced taking the second communication device sending a signal to the first communication device as an example, and the scheme provided in FIG. 4 can be regarded as a possible embodiment in the communication scenario provided in FIG. 3.

[0120] For easy understanding, the interaction between the first communication device, the second communication device and the positioning management device is introduced in FIG. 4. In the embodiments of the present application, the first communication device can be the network device, the chip (system) inside the network device in the foregoing FIGS. 2A, 2B, 2C, 2D, 2E or 2F. In the embodiments of the present application, the second communication device can be the terminal device or the chip (system) inside the terminal in the foregoing FIGS. 2A, 2B, 2C, 2D, 2E or 2F. The positioning management device in the embodiments of the present application can be the positioning management device or the chip (system) in the positioning management device involved in the foregoing FIGS. 2A, 2B, 2C, 2D, 2E or 2F. The positioning management device can include one or more of LMF, LMC or LLMF.

[0121] As shown in FIG. 4, the method can include the following steps.

[0122] Step 401, the second communication device sends a first signal.

[0123] Correspondingly, the first communication device receives the first signal through N antennas. N is a positive integer.

[0124] One of the N antennas can include one physical antenna element or one antenna port. One physical antenna element can also be referred to as one antenna element. One antenna port can be understood as one logical antenna port, and one antenna port can include one or more physical antenna elements.

[0125] The first signal can be, for example, a signal used for positioning. Examples of the first signal can be found in the foregoing, which will not be repeated here. For ease of understanding, the first signal is taken as an SRS signal in FIG. 4 for illustration.

[0126] In one possible implementation, before step 401, the second communication device can receive configuration information of the first signal. The configuration information of the first signal can include, for example, resource information of the first signal, such as time domain resource and frequency domain resource. In this way, the second communication device can send the first signal on the resource of the first signal according to the configuration information of the first signal.

[0127] For example, the first communication device or the positioning management device sends the configuration information (e.g., SRS configuration information) of the first signal to the second communication device. In another possible implementation, the positioning management device can send a positioning information request to the first communication device, and the first communication device can send a positioning information response to the positioning management device. The positioning information request can request positioning of the second communication device. The first communication device can generate the configuration information (e.g., SRS configuration information) of the first signal based on the positioning information request, and send the configuration information (e.g., SRS configuration information) of the first signal to the second communication device. In another possible implementation, the first communication device can also feed back the configuration information (e.g., SRS configuration information) of the first signal to the positioning management device in the positioning information response. In order for the positioning management device to subsequently send the configuration information (e.g., SRS configuration information) of the first signal to other communication devices (the first communication device is, for example, a terminal device, the second communication device is, for example, a serving base station, and the other communication device is, for example, a neighbor base station), so that the other communication device (e.g., a neighbor base station) measures the received first signal and obtains measurement results. The scheme for the other communication device (e.g., a neighbor base station) to measure the first signal to obtain measurement results can refer to the scheme of the second communication device, which will not be repeated here.

[0128] In step 402, the first communication device sends measurement result indication information.

[0129] Correspondingly, the positioning management device receives the measurement result indication information.

[0130] Before step 402, the first communication device measures the first signal through the N antennas respectively to obtain N first measurement results. In order to distinguish, the measurement results obtained by the first communication device are referred to as first measurement results in the embodiments of the present application. The N first measurement results are obtained according to the first signal.

[0131] The measurement result indication information includes information for indicating at least one measurement result. The measurement result indication information can indicate one or more measurement results. The measurement result may, for example, include relevant information of a transmission time of the first signal, for example, can include a TOA, a relative time of arrival (RTOA), a time of flight (TOF), or a time difference of arrival (TDOA), etc. For ease of understanding, part of the content in the embodiments of the present application is introduced by taking the measurement result as a TOA, and the TOA in the embodiments of the present application can be replaced by other parameters. The measurement result indication information is determined according to N first measurement results. One of the N first measurement results is obtained by measuring the first signal by one of the N antennas. One of the N antennas can include one antenna element or one antenna port, and specific content is described above and will not be repeated here.

[0132] For example, N is three, and the three antennas of the first communication device are antenna #11, antenna #12 and antenna #13. The second communication device sends a first signal. The antenna #11, the antenna #12 and the antenna #13 of the first communication device can all receive the first signal. The first communication device measures the first signal according to the antenna #11 to obtain a first measurement result #11. The first communication device measures the first signal according to the antenna #12 to obtain a first measurement result #12, and the first communication device measures the first signal according to the antenna #13 to obtain a first measurement result #13. The first measurement result #11, the first measurement result #12 and the first measurement result #13 are N first measurement results.

[0133] The measurement result indicated by the measurement result indication information can include at least one first measurement result, and / or a measurement result determined according to at least one first measurement result. For example, the measurement result indicated by the measurement result indication information can be one or more first measurement results, for example, the measurement result can include a median value, a minimum value or a maximum value of a plurality of first measurement results, etc. For another example, the measurement result indicated by the measurement result indication information can be obtained by performing certain operations on a plurality of first measurement results, for example, the measurement result can be an average value or a weighted average value of a plurality of first measurement results. In this way, the flexibility of the scheme can be improved. In combination with the above example, for example, the measurement result indicated by the measurement result indication information includes at least one of the first measurement result #11, the first measurement result #12 or the first measurement result #13; and / or an average value (or a weighted average value) of the first measurement result #11, the first measurement result #12 and the first measurement result #13.

[0134] The measurement result indicated by the measurement result indication information can be one or multiple. For example, the measurement result is TOA, the measurement result indication information can include information for indicating one or multiple TOAs. The information for indicating one or multiple TOAs can include a TOA, or other information capable of indicating a TOA.

[0135] For example, in the case that the measurement result indication information indicates multiple measurement results, the measurement result indication information can further include at least one measurement result, and information of multiple measurement result value rules. The information of multiple measurement result value rules can include, for example, information of a variation amount between two measurement results in the multiple measurement results. For example, the information of a variation amount between two measurement results in the multiple measurement results can include a TOA difference between two adjacent antennas in at least one direction, a TOA value variation speed between adjacent antennas in at least one direction, a TOA value variation slope between adjacent antennas in at least one direction, etc.

[0136] A direction in the at least one direction in the embodiments of the present application can include a direction on a distribution map of the N antennas of the first communication device. For example, the at least one direction includes a horizontal direction and / or a vertical direction. The horizontal direction can refer to a horizontal direction on the distribution map of the N antennas, and the vertical direction can refer to a vertical direction on the distribution map of the N antennas. Taking the aforementioned FIG. 3 as an example, for example, the horizontal direction includes a direction from the antenna at coordinate (0, 0) to the antenna at coordinate (0, Q-1), and the vertical direction includes a direction from the antenna at coordinate (0, 0) to the antenna at coordinate (P-1, 0). This example is for illustration only, and the definitions of the horizontal direction and the vertical direction can vary according to different observation directions or different definitions. For example, the horizontal direction can also be defined as a direction from the antenna at coordinate (0, 0) to the antenna at coordinate (P-1, 0), and the vertical direction can also be defined as a direction from the antenna at coordinate (0, 0) to the antenna at coordinate (0, Q-1). The at least one direction can include other directions in addition to the horizontal direction and the vertical direction, such as a first direction. For example, the first direction can be a diagonal direction, such as a direction from the antenna at coordinate (0, 0) to the antenna at coordinate (P-1, Q-1).

[0137] The following shows an example of the N first measurement results obtained by the first communication device by Table 1. In Table 1, 32 antennas are taken as an example, and the 32 antennas of the first communication device are distributed in 8*4, i.e., the 32 antenna arrays have 8 rows in the vertical direction and 4 columns in the horizontal direction (in combination with FIG. 3, the example is taken as Q=4 and P=8 in FIG. 3). In the embodiments of the present application, it can mean multiplication. Table 1 shows the TOA corresponding to each antenna (the example is taken as TOA as an example). As shown in Table 1, the TOA value obtained by measuring the first signal by the antenna with coordinates (0, 0) in the 32 antennas of the first communication device is 76.30 ns. The meanings of the remaining parameters are described herein and will not be described again.

[0138] Table 1 shows an example of the N first measurement results obtained by the first communication device (unit, ns)

[0139] The measurement result indication information sent by the first communication device can include one or more TOAs of the 32 TOAs. When multiple TOAs need to be reported, in order to save signaling overhead, the measurement result indication information can include information of the value rule of multiple measurements. It can be seen through analysis that the TOA difference between two adjacent antennas in the horizontal direction is 0.02 ns, and the TOA difference between two adjacent antennas in the vertical direction is 0.57 ns. Based on this, the first communication device can send a tuple <76.30 ns, (0, 0), 0.02 ns, 0.57 ns>. Among them, 76.30 ns and (0, 0) represent that the TOA of the antenna with coordinates (0, 0) is 76.30 ns, 0.02 ns represents the TOA difference (or represents the change speed, change slope, etc. in the horizontal direction) between two adjacent antennas in the horizontal direction, and 0.57 ns represents the TOA difference (or represents the change speed, change slope, etc. in the vertical direction) between two adjacent antennas in the vertical direction. In this example, for example, 76.30 ns, 0.02 ns, and 0.57 ns belong to the measurement result indication information, (0, 0) is the coordinates of the antenna corresponding to the TOA, and (0, 0) can belong to the first information (the first information indicates the information of the antenna corresponding to the measurement result indication information). Or <76.30 ns, (0, 0), 0.02 ns, 0.57 ns> belongs to the measurement result indication information, and the measurement result indication information is used to indicate the TOA values of the 32 antennas. It can be seen from the example that the measurement result indication information can indicate the values of the 32 TOAs through the tuple <76.30 ns, (0, 0), 0.02 ns, 0.57 ns>, which saves the number of bits occupied by the measurement result indication information, and in turn saves resources.

[0140] In a possible implementation, the first communication device can send the measurement result indication information based on a new radio positioning protocol annex (NRPPa) protocol. For example, the measurement result indication information can be carried in an uplink (UL) RTOA measurement information element. The first communication device can add a field in the UL RTOA measurement information element, for example, the field can be named as a Delta UL-RTOA field (other names can also be used, and this name is an example), which can carry information of multiple measurement result value rules, used to represent the change rule of the measurement result of the antenna. For example, the Delta UL-RTOA field can carry 0.02 ns and 0.57 ns in the example of Table 1 above, or carry the <76.30 ns, (0, 0), 0.02 ns, 0.57 ns> tuple.

[0141] In step 403, the first communication device sends the first information.

[0142] Correspondingly, the positioning management device receives the first information.

[0143] The first information can be carried in the same message as the measurement result indication information, or can be carried in different messages.

[0144] The first information sent by the first communication device is used to indicate the information of the antenna corresponding to the measurement result indication information. For example, the first information can include the position information (information A1) of the antenna corresponding to the measurement result indication information in the N antennas, and / or the information (information A2) of the relationship between the measurement result indicated by the measurement result indication information and the N first measurement results. The relationship between the measurement result indicated by the measurement result indication information and the N first measurement results can also implicitly indicate the antenna information, for example, the measurement result indicated by the measurement result indication information is the average or median of the N first measurement results, and the antenna corresponding to the measurement result indication information is the antenna in the middle region of the N antennas. These information can assist the positioning management device to determine the position of the antenna, and then the positioning management device can more accurately calculate the distance between the second communication device and the antenna based on the position of the antenna and the measurement result indication information, so as to improve the positioning accuracy based on the distance.

[0145] The information A1 and the information A2 are introduced below respectively.

[0146] The information A1 is the position information of the antenna corresponding to the measurement result indication information in the N antennas.

[0147] The position information of the antenna corresponding to the measurement result indication information in the N antennas may, for example, indicate a certain position (e.g., a central position or another position) of the antenna corresponding to the measurement result indication information in the N antennas.

[0148] For example, the position information of the antenna corresponding to the measurement result indication information in the N antennas includes at least one of the following: an index of the antenna corresponding to the measurement result indication information; coordinate information of the antenna corresponding to the measurement result indication information; or information of a relative position relationship between the antenna corresponding to the measurement result indication information and a reference position. These manners can assist the positioning management apparatus in determining the position of the antenna, and can also save signaling overhead.

[0149] When the first information indicates the index of the antenna corresponding to the measurement result indication information, the positioning management apparatus can find the position of the antenna according to a preset correspondence between the antenna index and the antenna position. For example, the message sent by the first communication apparatus includes: <TOA#11, antenna index #11>. Here, TOA#11 is the measurement result indication information, and antenna index #11 is the first information. The TOA#11 is a TOA obtained by the antenna with index #11 measuring the first signal. The positioning management apparatus can find the position of the antenna with index #11, and then perform positioning on the second communication apparatus according to the position and the TOA#11.

[0150] The coordinate information of the antenna corresponding to the measurement result indication information may, for example, be in the coordinate form shown in FIG. 3. For example, the message sent by the first communication apparatus includes: <TOA#11, (0, 0)>. Here, TOA#11 is the measurement result indication information, and (0, 0) is the first information. When the antenna is an antenna, the coordinate information of the antenna is the coordinate information of the antenna. When the antenna is an antenna port, the coordinate information of the antenna is the coordinate information of the antenna port. The antenna port is a logical antenna port composed of one or more antennas, and therefore the coordinate information of the antenna port is set more flexibly. For example, the coordinate information of the antenna port may be the coordinate information of a position in a region where the antenna port is located, for example, the coordinate information of the center of the antenna port, or the coordinate information of an antenna in the antenna port, and so on. The positioning management apparatus can obtain the position of the antenna according to the index of the antenna, and then perform positioning on the second communication apparatus according to the position and the TOA#11. The coordinate information of the antenna may be information of the coordinates of the antenna in a certain coordinate system (such as a geodetic coordinate system). The coordinates of the antenna may be identified using coordinate values in a two-dimensional coordinate system, or using coordinate values in a three-dimensional coordinate system.

[0151] The information of the relative position relationship between the antenna corresponding to the measurement result indication information and the reference position can assist the positioning management device to determine the position of the antenna. The reference position in the embodiments of the present application can be a pre-defined position, which can be a position on the antenna panel or can not be a position on the antenna panel. The positioning management device can determine the position of the antenna based on the reference position and the position relationship between the antenna and the reference position. In a possible implementation, the reference position can be the position of the ARP, for example. The relative position information between the antenna and the reference position can be information for indicating (Δx, Δy), where Δx is the distance between the projections of the antenna and the reference position (e.g. the ARP) on the x-axis (or the horizontal direction), and Δy is the distance between the center positions of the first antenna panel and the second antenna panel on the y-axis (or the vertical direction). For example, the message sent by the first communication device includes: <TOA#11, (Δx1, Δy1)>. Wherein, TOA#11 is the measurement result indication information, and (Δx1, Δy1) is the first information. (Δx1, Δy1) can represent the phase position relationship between the antenna corresponding to TOA#1 and the ARP, for example, Δx1 can represent the distance between the antenna and the ARP in the horizontal direction, and Δy1 can represent the distance between the antenna and the ARP in the vertical direction. If the coordinate position of the ARP is (a1, b1), the coordinate of the antenna corresponding to TOA#1 is (a1+Δx1, b1+Δy1). The positioning management device can position the second communication device according to the coordinate of the antenna corresponding to TOA#11.

[0152] In yet another possible implementation, the position information of the antenna corresponding to the measurement result indication information in the N antennas includes information for indicating the position of the antenna corresponding to the measurement result indication information. For example, the position information of the antenna corresponding to the measurement result indication information in the N antennas includes information for indicating that the antenna corresponding to the measurement result indication is an antenna at the center position of the antenna panel. For example, a specified bit value can be used to identify the special position of the antenna, for example, 1 bit of a specified field is used to represent whether the antenna is at the center position of the antenna panel, if the bit value is 1, it indicates that the antenna is at the center position of the antenna panel; if the bit value is 0, it indicates that the antenna is not at the center position of the antenna panel. For example, the message sent by the first communication device includes: <TOA#11, 1 (information for indicating that the antenna corresponding to TOA#11 is an antenna at the center position of the antenna panel)>. Wherein, TOA#11 is the measurement result indication information, and 1 is the first information. The 1 indicates that the antenna corresponding to TOA#11 is an antenna at the center position of the antenna panel.

[0153] In a possible implementation, the first communication device can send the first information based on a LTE positioning protocol annex (LPPa) protocol / NRPPa protocol. The first information can be carried in a UL RTOA measurement information element. For example, the first communication device can add a receive Antenna Element information field in the UL RTOA measurement information element, and the receive Antenna Element information field can carry position information of an antenna corresponding to the measurement result indication information in the N antennas. For example, the receive Antenna Element information field can carry at least one of an index of the antenna, coordinate information of the antenna, or relative position relationship information between the antenna and a reference position.

[0154] The information A2 includes information about a relationship between the measurement result indicated by the measurement result indication information and the N first measurement results.

[0155] For example, the information about the relationship between the measurement result indicated by the measurement result indication information and the N first measurement results includes information that the measurement result indicated by the measurement result indication information is an average value and / or a median of the N first measurement results.

[0156] For example, the N antennas can be P*Q antennas, and the N first measurement results can be values of the P*Q antenna array shown in FIG. 3. The N first measurement results are represented in a matrix form.

[0157] The measurement result sent by the first communication device can be a measurement result in the N first measurement results or a measurement result calculated according to the N first measurement results.

[0158] For example, if the measurement indicated by the measurement indication information is the average (or median) of the N first measurements, a specified bit value can be used to identify whether the measurement sent by the first communication device is the average (or median). For example, a 1-bit field of a specified field can be used to indicate whether the measurement is the average (or median), where 1 indicates that the measurement is the average (or median), and 0 indicates that the measurement is not the average (or median). For example, the message sent by the first communication device includes: <TOA#11, 1 (information indicating that TOA#11 is the average or median)> where TOA#11 is the measurement indication information, and 1 is the first information. According to the bit value 1 of the specified bit, the positioning management device can determine that the TOA#11 is the average (or median) of the N first measurements. Then, the positioning management device can determine that the antenna corresponding to the TOA#11 is an antenna that is relatively central (or central, or in a central region) to the antenna panel. Then, the positioning management device can use the position of the relatively central antenna and the TOA#11 to locate the second communication device.

[0159] In a possible implementation, the first communication device can send the first information based on the NRPPa protocol. The first information can be carried in a UL RTOA measurement information element. For example, the first communication device can add a UL RTOA type field in the UL RTOA measurement information element, where the UL RTOA type field can carry information about the relationship between the measurement indicated by the measurement indication information and the N first measurements. For example, the UL RTOA type field can carry information about whether the measurement indicated by the measurement indication information is the average (and / or median) of the N first measurements.

[0160] In another possible implementation, the information that the measurement indicated by the measurement indication information is the average (and / or median) of the N first measurements can also indicate that the antenna corresponding to the measurement indication is an antenna at the central position of the antenna panel. Based on this, in a possible implementation, the UL RTOA type field can also be used to carry information indicating whether the antenna corresponding to the measurement indication is an antenna at the central position of the antenna panel.

[0161] The step 403 can or can not be performed. In the case that the step 403 is not performed, the measurement result indication information reported by the first communication device is the measurement result indication information satisfying the preset rule, for example, the preset rule indicates that the first communication device reports the average value or the median of N first measurement results. For another example, the preset rule indicates that the first communication device reports the first measurement result of the first signal measured by the antenna with the coordinate (x1, y1), and the values of x1 and y1 are values specified by the preset rule, which can be 0 or a positive integer.

[0162] In step 404, the positioning management device determines the position information of the second communication device.

[0163] If the positioning management device also receives the first information, the positioning management device determines the position information of the second communication device according to the measurement result indication information and the first information.

[0164] If the positioning management device does not receive the first information, the positioning management device can determine the antenna information corresponding to the measurement result indication information according to the preset rule, and then determine the position information of the second communication device according to the antenna information corresponding to the measurement result indication information and the measurement result indication information.

[0165] Since the first communication device sends the first information, the positioning management device can more accurately determine the position of the second communication device in combination with the first information and the measurement result indication information, thereby improving the positioning accuracy. For example, the positioning management device can calculate the distance between the antenna measuring the first signal (rather than the position of the entire antenna panel of the first communication device) and the second communication device in combination with the measurement result corresponding to the antenna, so that the distance value is more accurate, and then the positioning accuracy can be improved based on the more accurate distance value.

[0166] Based on the embodiments shown in FIGS. 1, 2A, 2B, 2C, 2D, 2E, 2F, 3 and 4 and other content described above, FIG. 5 exemplarily shows a flow diagram of a signal measurement result transmission method provided by an embodiment of the present application. The scheme shown in FIG. 5 can be regarded as an extended implementation of the embodiment of FIG. 4. In FIG. 5, the interaction between the LMF and the ORAN module is taken as an example for introduction. As shown in FIG. 5, the second communication device can be replaced by a certain module in the ORAN, for example, can be replaced by a DU, CU or RIC module. The DU, CU or RIC can also be other names, for example, the DU can be O-DU or other names, the CU can also be replaced by O-CU or other names, etc.

[0167] As shown in FIG. 5, the method comprises:

[0168] In step 501, the second communication device sends a first signal.

[0169] Correspondingly, the first communication device receives the first signal through the N antennas.

[0170] The content of step 501 can refer to the description of the aforementioned step 401, and will not be repeated here.

[0171] Step 502, the first communication device sends the measurement result indication information.

[0172] Correspondingly, the positioning management device receives the measurement result indication information.

[0173] The content of step 502 can refer to the description of the aforementioned step 402, and will not be repeated here.

[0174] Step 503, the first communication device sends the first information.

[0175] Correspondingly, the positioning management device receives the first information.

[0176] The content of step 503 can refer to the description of the aforementioned step 403, and will not be repeated here.

[0177] Step 504, the positioning management device determines the position information of the second communication device.

[0178] The content of step 504 can refer to the description of the aforementioned step 404, and will not be repeated here.

[0179] In FIG. 5, the second communication device is replaced by a certain module in ORAN as an example, and the related schemes and beneficial effects of FIG. 5 can refer to the related description of the aforementioned FIG. 4, and will not be repeated here.

[0180] Based on the embodiments shown in FIGS. 1, 2A, 2B, 2C, 2D, 2E, 2F, 3, 4 and 5 and the above-mentioned other contents, FIG. 6 exemplarily shows a flow diagram of a signal measurement result transmission method provided by the embodiments of the present application. FIGS. 3, 4 and 5 take the second communication device sending the first signal to the first communication device as an example for introduction, and the embodiment shown in FIG. 6 takes the first communication device sending the signal to the second communication device as an example for introduction.

[0181] As shown in FIG. 6, the first communication device can include R*S antenna ports. One antenna port can include one or more antenna elements. In FIG. 6, one antenna port is taken as one antenna element for example. In FIG. 6, each antenna port can be identified by a coordinate value. For example, the antenna port identified as (0, 0) in FIG. 6 can represent an antenna port with a coordinate of (0, 0), the antenna port identified as (R-1, 0) can represent an antenna port with a coordinate of (R-1, 0), and so on, and the like, and details are similar and will not be repeated. In an embodiment of the present application, the coordinate value of one antenna port can be the coordinate value of a position in the region formed by the antenna elements included in the antenna port, for example, the coordinate value of a relatively central region in the region formed by the antenna elements included in the antenna port. For another example, the coordinate value of one antenna port can be the coordinate value of one antenna element included in the antenna port, for example, the coordinate value of a relatively central antenna element in the region formed by the antenna elements included in the antenna port.

[0182] As shown in FIG. 6, the difference Δdis2 between the distance between the antenna port with a coordinate of (0, 0) and the second communication device and the distance between the antenna port with a coordinate of (R-1, 0) and the second communication device satisfies the following formula (2):

[0183] In formula (2), d2 is the distance between the adjacent antennas in the vertical direction, k2 is the number of antennas between the antenna port with a coordinate of (0, 0) and the antenna port with a coordinate of (R-1, 0), θ2 is the angle between the second signal and the second line, and the second line is the line between the antenna port with a coordinate of (0, 0) and the antenna port with a coordinate of (R-1, 0). In the formula, the antenna port with a coordinate of (0, 0) and the antenna port with a coordinate of (R-1, 0) are taken as examples, and the distance calculation between other antenna ports is similar and will not be repeated.

[0184] In the scheme provided by the embodiment of the present application, the first communication device can send one or more second signals. In FIG. 6, two second signals sent by the first communication device are taken as examples for illustration. For example, the first communication device sends the second signal #1 through the antenna port with a coordinate of (R-1, 0), and the first communication device sends the second signal #2 through the antenna port with a coordinate of (0, 0). The second communication device measures the second signal to obtain a measurement result (for example, TOA). The second communication device can send the measurement result (for example, TOA) to the positioning management device, so that the positioning management device positions the second communication device according to the measurement result.

[0185] Since the measurement results corresponding to the second signals sent by different antenna ports are different (for example, there is a difference between the time delays of the second signals sent by different antenna ports to reach the second communication device), especially when the difference between the antenna ports of the first communication device is large, the measurement results corresponding to the signals sent by the two antenna ports are greatly different. If the difference is not considered when positioning the second communication device, but simply ignoring the difference between the antenna ports, the position of the entire antenna panel of the first communication device (for example, the center position of the entire antenna panel) and the measurement results are used to calculate the position of the second communication device, instead of using the information of the antenna port corresponding to the measurement results (for example, the position of the antenna port) and the measurement results to calculate the position of the second communication device, which will result in a large final positioning error.

[0186] In the embodiments of the present application, the positioning management device can position the second communication device according to the received measurement results and the information of the antenna port corresponding to the measurement results (for example, according to the position of the antenna port corresponding to the measurement results, instead of the position of the entire antenna panel of the first communication device), so that the positioning accuracy can be improved.

[0187] The beneficial effects of the scheme will be introduced below through an example.

[0188] For example, the first communication device sends a second signal through an antenna port, and the second communication device measures the second signal to obtain a measurement result, for example, a TOA#20. The positioning management device will calculate the distance between the second communication device and the first communication device based on the position of the antenna panel (instead of the actual position of the antenna port sending the second signal) and the TOA#20. Since the distance value is not calculated based on the position of the antenna port sending the second signal, the distance value will also be inaccurate, which will result in low positioning accuracy of the second communication device.

[0189] In the scheme provided in the embodiments of the present application, the first communication device can send M second signals through M antenna ports, and M can be 1 or other positive integers. The second communication device performs measurement on each received second signal to obtain a measurement result corresponding to each second signal. The second communication device obtains M measurement results in total. For example, the second communication device sends TOA#21, and TOA#21 is the TOA corresponding to the antenna port with coordinates (0, 0), then the positioning management device can calculate the distance between the second communication device and the antenna port with coordinates (0, 0) of the first communication device according to the information (for example, the position) of the antenna port with coordinates (0, 0) (rather than according to the position of the entire antenna panel of the first communication device), and the measurement result is more accurate, and then the position of the second communication device can be calculated according to the distance. It can be seen that in the calculation, the distance between each measurement result corresponding antenna port and the second communication device can be calculated more accurately, so that the second communication device can be positioned more accurately.

[0190] Based on the embodiments shown in FIG. 1, FIG. 2A, FIG. 2B, FIG. 2C, FIG. 2D, FIG. 2E, FIG. 2F, FIG. 3, FIG. 4, FIG. 5 and FIG. 6, and other content described above, FIG. 7 exemplarily shows a flow diagram of another signal measurement result transmission method provided in the embodiments of the present application. FIG. 7 can be regarded as a possible implementation of the scenario provided in FIG. 6. For easy understanding, FIG. 7 is introduced in the interaction between the first communication device, the second communication device and the positioning management device. The related introduction of the first communication device, the second communication device and the positioning management device can be referred to the description in FIG. 4. The difference from FIG. 4 is that FIG. 4 is introduced taking the second communication device sending the first signal as an example, and FIG. 7 is introduced taking the first communication device sending the second signal as an example.

[0191] As shown in FIG. 7, the method can include the following steps.

[0192] In step 701, the first communication device sends M second signals through M antenna ports.

[0193] Correspondingly, the second communication device receives M second signals. M is a positive integer.

[0194] The M second signals sent by the first communication device and received by the second communication device in the embodiments of the present application are taken as an example for introduction, and in actual application, the first communication device can send more second signals, and the second communication device can also receive more second signals.

[0195] One of the M antenna ports can include one physical antenna element or multiple physical antenna elements. For relevant content, please refer to the foregoing description of FIG. 4 or other locations about the antenna port and the physical antenna element, which will not be repeated here.

[0196] The second signal can be, for example, a signal for positioning. For examples of the second signal, please refer to the foregoing description, which will not be repeated here. For ease of understanding, FIG. 7 takes the PRS signal as an example for introduction.

[0197] In one possible implementation, before step 701, the second communication device can receive information indicating the antenna port corresponding to the second signal of the M second signals. The information of the antenna port corresponding to the second signal can include, for example, at least one of the port number, coordinate information or index of the antenna port used for transmitting the second signal. In this way, the second communication device can send the information of the antenna port corresponding to the measurement result to the positioning management device, so that the positioning management device performs positioning on the second communication device according to the received measurement result and the information of the antenna port corresponding to the measurement result.

[0198] The positioning management device or the first communication device sends the information indicating the antenna port corresponding to the second signal of the M second signals to the second communication device. For example, the positioning management device can send the configuration information (e.g., PRS configuration information) of the second signal to the second communication device through the NR downlink (DL) PRS information (info) element. The configuration information (e.g., PRS configuration information) of the second signal can include the DL PRS port (port) information (information, info), which can also be referred to as DL-PRS-Port-Info. The DL-PRS-Port-Info can indicate the information of the antenna port corresponding to the PRS.

[0199] The information indicating the antenna port corresponding to the second signal of the M second signals can be carried in the configuration information of the second signal. For example, the positioning management device or the first communication device sends the configuration information (e.g., PRS configuration information) of the second signal to the second communication device. For example, the configuration information of the second signal can also include, for example, the resource information of the second signal, such as the time domain resource and the frequency domain resource. The configuration information of the second signal can also include at least one of the period, the subcarrier spacing or the beam of the second signal. In this way, the second communication device can receive the second signal on the resource of the second signal.

[0200] In one possible implementation, the positioning management device can send a positioning information request to the first communication device, and the first communication device can send a positioning information response to the positioning management device. The positioning information request can request positioning of the second communication device. The first communication device can generate configuration information (e.g., PRS configuration information) of the second signal based on the positioning information request, and send the configuration information (e.g., PRS configuration information) of the second signal to the positioning management device. For example, the positioning information response can carry the configuration information (e.g., PRS configuration information) of the second signal. For example, the information of the antenna port number of the PRS can be introduced in the PRS configuration in the existing NRPPa protocol.

[0201] In another possible implementation, in the case that the second communication device has the capability of measuring signals from multiple antenna ports, the second communication device can send (e.g., to the positioning management device or other devices) information indicating the capability of measuring signals from multiple antenna ports. In this way, the positioning management device can know that the second communication device has the capability of measuring signals from multiple antenna ports. In this way, the positioning management device can send the configuration of the second signal transmitted through multiple antenna ports to the second communication device, so that the second communication device measures the second signal from multiple antenna ports based on its own capability. In another possible implementation, the second communication device can also send information indicating the number of antenna ports (e.g., 2, 4, 8, or other positive integer greater than 1) supported (e.g., maximum supported) by the second communication device. In this way, the positioning management device can send the configuration information of the second signal based on the capability of the second communication device, so as not to configure the second communication device with a configuration exceeding its capability.

[0202] In another possible implementation, the positioning management device can send a request message to the second communication device, the request message being used to request inquiry of whether the second communication device has the capability of measuring signals from multiple antenna ports. The request message, for example, includes the capability transfer signaling in LPPa. Correspondingly, in the case that the second communication device has the capability of measuring signals from multiple antenna ports, the second communication device can send information indicating the capability of measuring signals from multiple antenna ports, and / or information indicating the number of antenna ports (e.g., maximum supported) supported by the second communication device. For another example, in the case that the second communication device does not have the capability of measuring signals from multiple antenna ports, the second communication device can send information indicating the incapability of measuring signals from multiple antenna ports, or the second communication device does not reply information within a certain time period (e.g., within a certain time length of receiving the request message).

[0203] At step 702, the second communication device sends measurement result indication information.

[0204] Correspondingly, the positioning management apparatus receives the measurement result indication information.

[0205] Before step 702, the second communication apparatus can measure the received M second signals to obtain M second measurement results. For distinction, the measurement results obtained by the second communication apparatus are referred to as second measurement results in the embodiments of the present application. The M second measurement results are obtained according to the M second signals. The M second signals can be transmitted in a time-division manner, and correspondingly, the second communication apparatus can measure the M second signals in time division to obtain the M second measurement results. Alternatively, the M second signals are transmitted in other manners, such as frequency division.

[0206] The measurement result indication information includes information for indicating at least one measurement result. The measurement result indication information can indicate one or more measurement results. The measurement result may, for example, include relevant information of the transmission time of the second signal, such as TOA, etc. In the embodiment provided in FIG. 7, the measurement result indication information transmitted by the second communication apparatus is determined according to the M second measurement results. The M second measurement results are obtained according to the M second signals, and one of the M second measurement results is obtained by measuring one of the M second signals.

[0207] For example, M is three, and the three antenna ports of the first communication apparatus are antenna port #21, antenna port #22 and antenna port #23. The first communication apparatus transmits second signal #21 through antenna port #21, and the second communication apparatus measures the second signal #21 to obtain second measurement result #21. The first communication apparatus transmits second signal #22 through antenna port #22, and the second communication apparatus measures the second signal #22 to obtain second measurement result #22. The first communication apparatus transmits second signal #23 through antenna port #23, and the second communication apparatus measures the second signal #23 to obtain second measurement result #23. The second measurement result #21, the second measurement result #22 and the second measurement result #23 are the M second measurement results.

[0208] The measurement result indicated by the measurement result indication information can include at least one second measurement result, and / or a measurement result determined according to the at least one second measurement result. The measurement result determined according to the at least one second measurement result can be obtained by performing certain operations on the plurality of second measurement results, for example, can be an average value or a weighted average value of the plurality of second measurement results, etc. In combination with the above examples, for example, the measurement result indicated by the measurement result indication information includes at least one of the second measurement result #21, the second measurement result #22 or the second measurement result #23, and / or an average value (or a weighted average value) of the second measurement result #21, the second measurement result #22 and the second measurement result #23.

[0209] The measurement result indicated by the measurement result indication information can be one or multiple. For example, the measurement result is TOA, and the measurement result indication information can include information for indicating one or more TOAs. The information for indicating one or more TOAs can include a TOA, or other information capable of indicating a TOA.

[0210] For example, in the case where the measurement result indication information indicates multiple measurement results, the measurement result indication information can further include at least one measurement result, and information of a value rule of the multiple measurement results. The information of the value rule of the multiple measurement results can include, for example, information of a variation amount between two measurement results in the multiple measurement results. For example, the information of the variation amount between two measurement results in the multiple measurement results can include a TOA difference between two adjacent antenna ports in at least one direction, a variation speed of the TOA value between the adjacent antenna ports in at least one direction, a variation slope of the TOA value between the adjacent antenna ports in at least one direction, etc. For related examples, refer to the aforementioned examples of the measurement result indication information sent by the first communication device, which will not be described herein.

[0211] In step 703, the second communication device sends second information.

[0212] Correspondingly, the positioning management device receives the second information.

[0213] The second information can be carried in the same message as the measurement result indication information, or can be carried in different messages.

[0214] The second information sent by the second communication device is used to indicate information of the antenna port corresponding to the measurement result indication information. For example, the second information can include position information of the antenna port corresponding to the measurement result indication information in the M antenna ports (information B1); and / or, information of the relationship between the measurement result indicated by the measurement result indication information and the M second measurement results (information B2). The relationship between the measurement result indicated by the measurement result indication information and the M second measurement results can also implicitly indicate the antenna port information. For example, if the measurement result indicated by the measurement result indication information is the average or median of the M second measurement results, the antenna port corresponding to the measurement result indication information is the antenna port in the middle region of the M antenna ports.

[0215] The information B1 and the information B2 will be introduced respectively as follows.

[0216] The information B1 is position information of the antenna port corresponding to the measurement result indication information in the M antenna ports.

[0217] The position information of the antenna port corresponding to the measurement result indication information in the M antenna ports can indicate a certain position (for example, a central position or other positions) of the antenna port corresponding to the measurement result indication information in the M antenna ports.

[0218] For example, the position information of the antenna port corresponding to the measurement result indication information in the M antenna ports includes at least one of the following: an index of the antenna port corresponding to the measurement result indication information; coordinate information of the antenna port corresponding to the measurement result indication information; or, information of the relative position relationship between the antenna port corresponding to the measurement result indication information and a reference position. The index of the antenna port can also include an antenna port number. The reference position can refer to the related description in the aforementioned information A1, and will not be described here again.

[0219] For example, if the second information indicates the index of the antenna port corresponding to the measurement result indication information, the positioning management device can find the position of the antenna port according to the preset correspondence between the antenna port index and the antenna port position. For example, the message sent by the second communication device includes: <TOA#21, antenna port number #21>. Wherein, TOA#21 is the measurement result indication information, and antenna port number #21 is the second information. The TOA#21 is the TOA obtained by the second communication device when measuring the second signal from the antenna port number #21. The positioning management device can find the position of the antenna port number #21, and then position the second communication device according to the position and the TOA#21.

[0220] The information B1 can refer to the content of the aforementioned information A1, and will not be described here again.

[0221] The information B2 is information of the relationship between the measurement result indicated by the measurement result indication information and the M second measurement results.

[0222] For example, the information about the relationship between the measurement result indicated by the measurement result indication information and the M second measurement results includes information that the measurement result indicated by the measurement result indication information is an average value and / or a median of the M second measurement results.

[0223] The measurement result sent by the second communication device can be a measurement result in the M second measurement results or a measurement result calculated according to the M second measurement results.

[0224] The information B2 can refer to the content of the aforementioned information A2, and will not be described again.

[0225] In a possible implementation, the second communication device can send the second information based on an LPPa protocol. For example, the second information can be carried in an NR DL TDOA measure element, which can also be referred to as an NR-DL-TDOA-MeasElement. The second communication device can add an NR DL PRS port field in the NR-DL-TDOA-MeasElement, and the NR DL PRS port field can carry the second information.

[0226] Step 703 can or can not be performed. In this case, the measurement result indication information reported by the second communication device is measurement result indication information that meets a preset rule. For example, the preset rule indicates that the second communication device reports an average value or a median of the M second measurement results. For another example, the preset rule indicates that the second communication device reports a second measurement result corresponding to an antenna port with coordinates (x1, y1). The values of x1 and y1 are values specified by the preset rule, which can be 0 or a positive integer.

[0227] In step 704, the positioning management device determines the position information of the second communication device.

[0228] If the positioning management device also receives the second information, the positioning management device determines the position information of the second communication device according to the measurement result indication information and the second information.

[0229] If the positioning management device does not receive the second information, the positioning management device can determine the antenna port information corresponding to the measurement result indication information according to the preset rule, and then determine the position information of the second communication device according to the antenna port information corresponding to the measurement result indication information and the measurement result indication information.

[0230] Since the second information is sent by the second communication device, the positioning management device can determine the position of the second communication device more accurately in combination with the second information and the measurement result indication information, thereby improving the positioning accuracy. For example, the positioning management device can calculate the distance between the antenna for measuring the second signal (rather than the position of the entire antenna panel of the first communication device) and the second communication device in combination with the position of the antenna and the measurement result corresponding to the antenna, so that the distance value is more accurate, and the positioning accuracy can be improved based on the more accurate distance value.
