[0125] The embodiments of the present application are described below in conjunction with the drawings in the embodiments of the present application.

[0126] First, in order to better understand the information transmission method disclosed in the embodiment of the present application, a communication system to which the embodiment of the present application is applicable is described.

[0127] The technical solution of the embodiment of the present application can be applied to various communication systems. For example, the global mobile communication system, the long term evolution (LTE) system, the universal mobile communication system, the fourth generation (4G) mobile communication system, the fifth generation (5G) mobile communication system, the new radio (NR) communication system, and with the continuous development of communication technology, the technical solution of the embodiment of the present application can also be used for subsequent evolved communication systems, such as the sixth generation (6G) mobile communication system, the seventh generation (7G) mobile communication system, and the like.

[0128] See also Figure 1 , Figure 1 It is a schematic diagram of a positioning architecture of a 5G network provided in an embodiment of the present application. The architecture includes user equipment (UE), next-generation radio access network (NG-RAN), and core network. Among them, NG-RAN includes next-generation LTE base stations (next-generation eNodeB, ng-eNB) and 5G base stations (gNodeB, gNB). The core network includes a positioning management function (LMF) network element and an access and mobility management function (AMF) network element. Optionally, Figure 1The illustrated architecture may also include an enhanced serving mobile location center (E-SMLC) and a secure user plane location (SUPL) location platform (SLP).

[0129] Among them, the UE and ng-eNB communicate through the LTE-Uu interface, the UE and gNB communicate through the NR-Uu interface, the ng-eNB and gNB communicate through the Xn interface, the ng-eNB and AMF network element communicate through the NG-C interface, the gNB and AMF network element communicate through the NG-C interface, and the AMF network element and LMF network element communicate through the NLs interface. The AMF network element can be used to receive positioning service requests for a certain UE initiated by other network elements in the network, and the AMF network element can also be used to send the received positioning service request to the LMF network element. The LMF network element can be used to be responsible for processing the received positioning service request and initiating related positioning processes.

[0130] in addition, Figure 1 The UE in the communication channel may also be replaced by a SUPL enabled terminal (SET), and the ng-eNB and / or gNB may also be replaced by a transmission point (TP).

[0131] In addition, LMF network elements Figure 1 In addition to the method shown in the core network and independent of the gNB, in actual applications, the LMF network element can also be integrated in the gNB. In the case where the LMF network element is integrated in the gNB, the LMF can also be called local LMF (i.e. local LMF).

[0132] See also Figure 2 , Figure 2 is a schematic diagram of a side link positioning architecture provided in an embodiment of the present application, which exemplarily illustrates a side link (SL)-based positioning architecture in three scenarios. Figure 2 As shown in the scenario 1, two UEs can realize mutual positioning by sending SL positioning reference signal (PRS) in the scenario without network coverage, for example, to realize mutual distance measurement or angle measurement. Figure 2 As shown in the second scenario, a UE can achieve positioning by receiving SL positioning reference signals sent by multiple road side units (RSUs). Figure 2As shown in Scenario 3, two UEs within the network coverage can achieve mutual positioning by sending SL positioning reference signals under the control of the base station, and send the positioning results to the LMF network element in the core network through the base station.

The terminal device can communicate with the network device, the terminal device can communicate with the positioning device, and the network device can communicate with the positioning device. The positioning device can be, for example, a location management server or a location server or a positioning center, and the positioning device can be, for example, a device or a logic module or a functional module. For example, the positioning device can be Figure 1 In the LMF network element. Figure 3 In the communication system shown, the positioning device is independent of the network device, the positioning device communicates with the terminal device through an external interface, and the positioning device communicates with the network device through an external interface.

[0134] In addition, in addition to Figure 3 In addition to the method in which the positioning device is independent of the network device, the positioning device can also be integrated into the network device. In the case where the positioning device is integrated into the network device, the positioning device is a part of the network device, and the positioning device communicates with the network device through the internal interface of the network device, and the positioning device communicates with the terminal device through the external interface of the network device. It can be seen that the network device has the function of a positioning device, and the network device can be used to perform related operations of the positioning device.

Among them, a base station is a device deployed in a wireless access network that can provide wireless communication functions, which can also be called a base station device, for example, an evolutionary NodeB (eNB or e-NodeB) in a long term evolution (LTE) system, ng-eNB, Node B, a base station (gNodeB or gNB) in a 5G system, a base station in a 6G system, a base station in a future communication system, etc. A base station can include a BBU and a remote radio unit (RRU). The BBU and RRU can be placed in different places, for example: the RRU is remote and placed in an area with high traffic volume, and the BBU is placed in a central computer room. The BBU and RRU can also be placed in the same computer room. The BBU and RRU can also be different components under one rack. Base stations can be in the following forms: macro base stations, micro base stations (also called small stations), pico base stations, relay stations, access points, balloon stations, etc.

[0137] Among them, ng-eNB is a device or apparatus deployed in a wireless access network that meets the 4G standard and provides wireless communication functions for terminal devices; ng-eNB can be various forms of base stations, access points, etc., and ng-eNB can also be a TRP that sends and receives reference signals. gNB is a device or apparatus deployed in a wireless access network that meets the 5G standard and provides wireless communication functions for terminal devices; gNB can be various forms of base stations, access points, etc., and gNB can also be a TRP that sends and receives reference signals, a transmission measurement function (TMF), etc.

[0138] In an optional implementation, the network device is a RAN node in a radio access network (RAN). The RAN may be a cellular system related to the third generation partnership project (3GPP), such as a 4G or 5G mobile communication system, or a future evolution system (such as a 6G mobile communication system). The RAN may also be an open access network (open RAN, O-RAN or ORAN), a cloud radio access network (cloud radio access network, CRAN), or a wireless fidelity (wireless fidelity, WiFi) system. The RAN may also be a communication system that integrates two or more of the above systems.

[0139] RAN nodes are sometimes also referred to as access network devices, RAN entities or access nodes, etc., which constitute part of the communication system to help terminals achieve wireless access. In one possible scenario, the RAN node may be a BS, eNodeB, access point (AP), TRP, gNB, a next-generation base station in a 6G mobile communication system, a base station in a future mobile communication system, or an access node in a WiFi system. RAN nodes may be macro base stations, micro base stations or indoor stations, relay nodes or donor nodes, or wireless controllers in CRAN scenarios. Optionally, RAN nodes may also be servers, wearable devices, vehicles or vehicle-mounted devices, etc. For example, the access network device in the vehicle to everything (V2X) technology may be an RSU.

[0140] In another possible scenario, multiple RAN nodes collaborate to assist the terminal in achieving wireless access, and different RAN nodes respectively implement part of the functions of the base station. For example, the RAN node can be a centralized unit (CU), a distributed unit (DU), a CU-control plane (CP), a CU-user plane (UP), or a radio unit (RU).

[0142] The following is a detailed description of the embodiments of the present application in conjunction with the accompanying drawings. The embodiments of the present application take terminal devices, network devices, and positioning devices as examples of execution subjects to illustrate the corresponding methods, but the present application does not limit the execution subjects of the methods. For example, the device in the method may also be a chip, a chip system, or a processor that supports the device to implement the corresponding method, or a logic module or software that can implement all or part of the functions of the device.

[0143] The present application embodiment provides an information transmission method 100, in which a terminal device receives a first reference signal through multiple antenna elements; the terminal device sends direction information of the terminal device, the direction information is determined based on the first information, and the first information is obtained by measuring the first reference signal.

The information transmission method 100 includes the following steps.

[0144] S101: A network device sends a first reference signal. Correspondingly, a terminal device receives the first reference signal through multiple antenna elements.

[0145] The terminal device receives the first reference signal through multiple antenna arrays, which means that the terminal device receives the first reference signal through some or all of the multiple antenna arrays. The multiple antenna arrays refer to two antenna arrays or more than two antenna arrays. Optionally, in the case where the multiple antenna arrays are more than two antenna arrays, at least three of the multiple antenna arrays are used to determine a plane, and it is understandable that at least three of the multiple antenna arrays are not on the same straight line.

[0146] In addition, the number of network devices that send the first reference signal can be one or more, that is, step S101 includes: each of the one or more network devices sends a first reference signal; accordingly, the terminal device receives the first reference signal from each of the one or more network devices through multiple antenna arrays. For example, the number of network devices is 2, and the number of antenna arrays of terminal device #1 is 3. Network device #1 sends a first reference signal #1, and network device #2 sends a first reference signal #2. Optionally, terminal device #1 receives the first reference signal #1 through part or all of antenna arrays among antenna array #1, antenna array #2, and antenna array #3, and receives the first reference signal #2 through part or all of antenna arrays among antenna array #1, antenna array #2, and antenna array #3.

[0147] Optionally, in the embodiment of the present application, the "antenna array" can be replaced by an antenna unit, or can also be replaced by an antenna module, or can also be replaced by an antenna port. In an optional manner, the antenna unit or the antenna module includes an antenna array. For ease of explanation, the embodiment of the present application is explained by taking the "antenna array" as an example.

[0148] Optionally, the network device is a RAN node, and the network device sends the first reference signal in step S101, which means: the RAN node sends the first reference signal.

[0149] In an optional implementation, the first reference signal is used for positioning, and the first reference signal may be, for example, a PRS. In addition, the embodiment of the present application does not limit the type of the first reference signal, and the first reference signal may be other signals used for positioning and for downlink transmission in addition to the PRS.

[0150] In an optional implementation, the method further includes: the terminal device receives a third request message, the third request message is used to request the terminal device to report a capability related to direction measurement. Optionally, the capability of the terminal device related to direction measurement includes one or more of the following: the capability of the terminal device to measure signals, the number of antenna arrays of the terminal device, or second information. The second information is used to indicate the relative position relationship of multiple antenna arrays, and the second information may be, for example, antenna array (pattern) information of the terminal device.

[0151] In an optional manner, in the case where the positioning device is independent of the network device, the third request information is sent directly by the positioning device to the terminal device; or, the third request information is sent by the positioning device to the terminal device through other network elements (for example, through the network device that provides services for the terminal device). In another optional manner, in the case where the positioning device is integrated into the network device, the third request information is sent by the network device that provides services for the terminal device to the terminal device.

[0152] In an optional implementation, the method further includes: the terminal device sends response information, the response information is used to indicate the capabilities of the terminal device related to direction measurement. In an optional manner, in the case where the positioning device is independent of the network device, the response information is sent directly by the terminal device to the positioning device; or, the response information is sent by the terminal device to the positioning device through other devices (for example, through the network device that provides services for the terminal device). In another optional manner, in the case where the positioning device is integrated in the network device, the response information is sent by the terminal device to the network device that provides services for the terminal device.

[0153] Optionally, the response information includes one or more of the following: indication information for indicating the ability of the terminal device to measure signals, the number of antenna arrays of the terminal device, and second information. The second information is used to indicate the relative position relationship of multiple antenna arrays, and the second information may be, for example, antenna array (pattern) information of the terminal device. In addition, in addition to the aforementioned content, the response information may also include information for indicating other capabilities related to direction measurement possessed by the terminal device, without limitation.

[0154] In an optional manner, the second information includes one or more of the following: the distance between different antenna elements in a plurality of antenna elements, the coordinates of a plurality of antenna elements, the absolute coordinates of a plurality of antenna elements, the relative coordinates between a plurality of antenna elements, and the angle between different antenna elements in a plurality of antenna elements. Optionally, the second information also includes the index of the antenna element corresponding to the one or more of the above items. In addition, in addition to the above-mentioned contents, the second information may also include other information that can represent the relative positional relationship of the plurality of antenna elements, without limitation.

[0155] Among them, the distance between different antenna arrays in the multiple antenna arrays is: the distance between different antenna arrays in some or all of the multiple antenna arrays. The coordinates or absolute coordinates of the multiple antenna arrays are: the coordinates or absolute coordinates of some or all of the multiple antenna arrays. The relative coordinates between the multiple antenna arrays are: the relative coordinates between different antenna arrays in some or all of the multiple antenna arrays. The angles between different antenna arrays in the multiple antenna arrays are: the angles between different antenna arrays in some or all of the multiple antenna arrays.

[0156] Optionally, the relative coordinates between the multiple antenna elements are: the coordinates of some or all of the multiple antenna elements relative to a reference point, where the reference point may be, for example, any one of the multiple antenna elements. Optionally, the second information also includes an index of the antenna element serving as the reference point and an index of the antenna element corresponding to the relative coordinates.

[0157] For example, the multiple antenna arrays of the terminal device are antenna array #1 (whose index is index #1), antenna array #2 (whose index is index #2) and antenna array #3 (whose index is index #3), the distance between antenna array #1 and antenna array #2 is d1, the distance between antenna array #1 and antenna array #3 is d2, and the distance between antenna array #2 and antenna array #3 is The second information includes: {index #1, index #2, d1}, {index #1, index #3, d2}, {index #2, index #3, Alternatively, antenna element #1 is used as the reference point, the coordinates of antenna element #2 relative to the reference point are (0, d1), the coordinates of antenna element #3 relative to the reference point are (d2, 0), and the second information includes: index #1, {index #2, (0, d1)}, {index #3, (d2, 0)}.

[0158] In the embodiment of the present application, the elements in the same "{}" have an associated relationship. For example, {index #1, index #2, d1} indicates that the distance between antenna element #1 corresponding to index #1 and antenna element #2 corresponding to index #2 is d1. For another example, with antenna element #1 as the reference point, {index #2, (0, d1)} indicates that the coordinates of antenna element #2 corresponding to index #2 relative to the reference point are (0, d1). This will not be repeated in the following text.

[0159] S102. The terminal device sends direction information of the terminal device, where the direction information is determined based on first information, and the first information is obtained by measuring a first reference signal.

[0160] Optionally, the first information is obtained by measuring the first reference signal, which can be replaced by: the first information is obtained based on the first reference signal. In an optional manner, the first information is obtained based on the first reference signal, including: the first information is obtained by measuring the first reference signal. In addition, the first information can also be obtained based on the first reference signal in other ways, without limitation.

[0161] In an optional manner, in the case where the positioning device is independent of the network device, the direction information is sent directly from the terminal device to the positioning device, or the direction information is sent from the terminal device to the positioning device through other devices (e.g., a network device that provides services for the terminal device). In another optional manner, in the case where the positioning device is integrated into the network device, the direction information is sent from the terminal device to the network device that provides services for the terminal device.

[0162] Optionally, the method also includes: the terminal device measures the first reference signal to obtain first information; and the terminal device determines direction information of the terminal device based on the first information.

[0163] In an optional implementation, the first information includes phases corresponding to the plurality of antenna elements. Alternatively, the first information includes at least one phase difference determined based on the phases corresponding to the plurality of antenna elements. The phases corresponding to the plurality of antenna elements are phases corresponding to at least two antenna elements of the plurality of antenna elements.

[0164] For example, the terminal device receives the first reference signal #1 and the first reference signal #2 through antenna elements #1 to antenna elements #4. The terminal device measures the first reference signal #1, and obtains that the phases corresponding to antenna elements #1 to antenna elements #4 are phase #1 to phase #4, respectively. The terminal device measures the first reference signal #2, and obtains that the phases corresponding to antenna elements #1 to antenna elements #4 are phase #5 to phase #8, respectively. Then, the first information includes: at least two phases from phase #1 to phase #8. Or, the first information includes at least one phase difference, and the at least one phase difference is determined based on at least two phases from phase #1 to phase #8. For example, the first information includes phase difference #1, phase difference #2, phase difference #3 and phase difference #4, wherein phase difference #1 is the difference between phase #1 and phase #2, phase difference #2 is the difference between phase #1 and phase #3, phase difference #3 is the difference between phase #5 and phase #6, and phase difference #4 is the difference between phase #5 and phase #7.

[0165] In addition, the phase corresponding to the antenna element can be, for example, the phase of the line of sight (LOS) path, the phase of the first path, the phase of the additional path, or the phase of the non-line of sight (NLOS) path, without limitation.

[0166] Optionally, the first information also includes one or more of the following: time of arrival (TOA) of the first reference signal, information obtained based on TOA measurement, angle of arrival (AOA) of the first reference signal, or reference signal receiving power (RSRP) corresponding to the first reference signal. Optionally, the information obtained based on TOA measurement may include, for example, one or more of the following: reference signal time difference (RSTD), relative time of arrival (RTOA), round-trip time (RTT), or rx-tx time difference, etc.

[0167] Optionally, the TOA of the first reference signal may be the TOA of the first reference signal on at least one path, the AOA of the first reference signal may be the AOA of the first reference signal on at least one path, and the RSRP corresponding to the first reference signal may be the RSRP corresponding to the first reference signal on at least one path. In addition, RSRP can also be referred to as reference signal received path power (RSRPP). In the embodiment of the present application, "path" can be understood as: the path that the signal passes through from the transmitting end to the receiving end. For example, the TOA of the first reference signal on at least one path can be understood as: the TOA of the first reference signal on at least one path from the network device to the terminal device.

[0168] In an optional implementation, the direction information of the terminal device is used to indicate the orientation of the terminal device, or to indicate the direction of movement of the terminal device, or to indicate the rotation direction of the terminal device. The direction information may be, for example, heading information, or may also be orientation information. In addition, the direction information may be represented by a vector. For example, the direction information is a three-dimensional vector (0, 0, 1), and the direction information indicates the direction of the Z axis. For another example, the direction information is a two-dimensional vector (0, 1), and the direction information indicates the direction of the Y axis. Alternatively, the direction information may also be represented by a set of transformation relationships. For example, the direction information is (α, β, γ), which indicates the rotation relationship between the first coordinate system and the second coordinate system. The direction information is described below, as described in the following optional implementations 1.1 to 1.4.

[0169] In implementation 1.1, the direction information is represented by the rotation relationship between the first coordinate system and the second coordinate system, the first coordinate system is a global coordinate system or a reference coordinate system, and the second coordinate system is a local coordinate system of the terminal device. In other words, the direction information can be represented by the rotation relationship between the first coordinate system and the second coordinate system.

[0170] In the embodiment of the present application, the relative position between the local coordinate system of the terminal device and the terminal device remains unchanged. It is understandable that when the terminal device is rotated or translated, the local coordinate system also performs corresponding rotation or translation operations. Among them, the rotation operation of the terminal device will change the orientation of the terminal device. For example, Figure 5 , a black circular pattern is used to represent the terminal device, with the terminal device as the coordinate origin, the positive direction of the x-axis represents the right side of the terminal device (right), the negative direction of the x-axis represents the left side of the terminal device (left), the positive direction of the y-axis represents the top side of the terminal device (up), the negative direction of the y-axis represents the bottom side of the terminal device (down), the positive direction of the z-axis represents the front side of the terminal device (forward), and the negative direction of the z-axis represents the back side of the terminal device (backward); the terminal device can rotate around one or more of the x-axis, y-axis, or z-axis. The rotation of the terminal device around the x-axis can also be called pitch, the rotation of the terminal device around the y-axis can also be called yaw, and the rotation of the terminal device around the z-axis can also be called roll.

[0171] In addition, the local coordinate system of the terminal device may be determined based on a reference point of the terminal device, for example, the local coordinate system of the terminal device uses the reference point of the terminal device as the coordinate origin. The reference point of the terminal device may be predefined, for example, the centroid of the plane where the multiple antenna arrays are located may be used as the reference point of the terminal device, or any antenna array of the multiple antenna arrays of the terminal device may be used as the reference point of the terminal device.

[0172] The global coordinate system and the reference coordinate system are coordinate systems that remain unchanged as the terminal device rotates or translates. It is understandable that when the terminal device rotates or translates, the global coordinate system and the reference coordinate system will not perform corresponding rotation or translation operations. For example, the origin of the global coordinate system is the origin of the earth, the z-axis of the global coordinate system points to the North Pole along the direction of the earth's axis, and the x-axis and y-axis of the global coordinate system are located in the equatorial plane. For another example, the reference coordinate system can be predefined or manually set.

[0173] Optionally, the rotation relationship between the first coordinate system and the second coordinate system is represented by a rotation angle between the first coordinate system and the second coordinate system. The direction information may include: a rotation angle between the first coordinate system and the second coordinate system.

[0174] Exemplarily, the rotation angles between the first coordinate system and the second coordinate system are α, β, and γ. Figure 6 , the first coordinate system consists of the x-axis, y-axis, and z-axis. Rotate the xy plane (i.e., the plane where the x-axis and y-axis are located) with the z-axis as the axis to obtain the x'-axis, y'-axis, and z'-axis (the z'-axis is the same as the z-axis), and α is the rotation angle between the x'-axis and the x-axis. Rotate the x'-z' plane (i.e., the plane where the x'-axis and the z'-axis are located) with the y'-axis to obtain the x"-axis, y"-axis (the y"-axis is the same as the y'-axis), and z"-axis, and β is the rotation angle between the z'-axis and the z'-axis. Rotate the y"-z" plane (i.e., the plane where the y"-axis and the z"-axis are located) with the x"-axis to obtain the x"'-axis (the x"'-axis is the same as the x"-axis), y"'-axis, and z"'-axis, and γ is the rotation angle between the y"'-axis and the y"-axis. The x"'-axis, y"'-axis, and z"'-axis constitute the second coordinate system.

[0175] In addition, the embodiment of the present application does not limit the specific form of using the rotation relationship between the first coordinate system and the second coordinate system to represent the direction information. For example, in the direction information, the rotation angle between the first coordinate system and the second coordinate system is represented in the form of a vector or a numerical value. Figure 6 Taking the illustrated scenario as an example, the direction information includes: (α, β, γ). Alternatively, the direction information includes: α, β, γ.

[0176] In implementation 1.2, the direction information is represented by the angle relationship between the first coordinate system and the second coordinate system, the first coordinate system is the global coordinate system or the reference coordinate system, and the second coordinate system is the local coordinate system of the terminal device. In other words, the angle relationship between the first coordinate system and the second coordinate system can be used to characterize the direction information. In addition, for the specific description of the global coordinate system, the reference coordinate system, and the local coordinate system of the terminal device, please refer to the relevant description in implementation 1.1, which will not be repeated here.

[0177] Optionally, the angle relationship between the first coordinate system and the second coordinate system is represented by the angle between the first coordinate system and the second coordinate system. The direction information may include: the angle between the first coordinate system and the second coordinate system. For example, taking the multiple antenna arrays of the terminal device as 3 antenna arrays as an example, combined with Figure 7 , the first coordinate system is a coordinate system consisting of the x-axis, y-axis, and z-axis, and the second coordinate system is a coordinate system consisting of the x'-axis, y'-axis, and z'-axis. The direction information can be used to indicate the angle between the x'-axis and the x-axis, the angle between the y'-axis and the y-axis, and the angle between the z'-axis and the z-axis.

[0178] In addition, the embodiment of the present application does not limit the specific form of using the angle relationship between the first coordinate system and the second coordinate system to represent the direction information. For example, in the direction information, the angle between the first coordinate system and the second coordinate system is represented in the form of a vector or a numerical value. Figure 7 Taking the scene shown as an example, the angle between the x' axis of the second coordinate system and the x axis of the first coordinate system is ρ1, the angle between the y' axis of the second coordinate system and the y axis of the first coordinate system is ρ2, and the angle between the z' axis of the second coordinate system and the z axis of the first coordinate system is ρ3. The direction information includes: (ρ1, ρ2, ρ3). Alternatively, the direction information includes: ρ1, ρ2, ρ3.

[0179] In implementation 1.3, the directional information is represented by the plane where the multiple antenna arrays are located. That is, the plane where the multiple antenna arrays are located can be used to characterize the directional information. In addition, the embodiment of the present application does not limit the specific form of using the plane where the multiple antenna arrays are located to represent the directional information. For example, in the directional information, the plane where the multiple antenna arrays are located is represented in the form of a vector or a numerical value.

[0180] For example, taking the case where the multiple antenna arrays of the terminal device are three antenna arrays, the first coordinate system is a coordinate system composed of an x-axis, a y-axis, and a z-axis. The distribution of the three antenna arrays of the terminal device in the first coordinate system is as follows: Figure 8 As shown, the plane where the three antenna elements are located is as follows Figure 8 The plane where the gray triangle pattern is located. In the first coordinate system, the plane equation corresponding to the plane where the three antenna elements are located can be shown as formula (1).

In other words, the normal vectors of the planes where the multiple antenna arrays are located can be used to characterize the directional information. In addition, the embodiments of the present application do not limit the specific form of using the normal vectors of the planes where the multiple antenna arrays are located to represent the directional information. For example, in the directional information, the normal vectors of the planes where the multiple antenna arrays are located are represented in the form of vectors or numerical values.

[0184] For example, taking the case where the multiple antenna arrays of the terminal device are three antenna arrays, the first coordinate system is a coordinate system composed of an x-axis, a y-axis, and a z-axis. The distribution of the three antenna arrays of the terminal device in the first coordinate system is as follows: Fig. 9 As shown, the plane where the three antenna elements are located is as follows Fig. 9The plane where the gray triangle pattern is located and the normal vectors of the plane where the three antenna arrays are located are as follows: Fig. 9 As shown by the dashed arrow in the middle. The plane equation corresponding to the plane where the three antenna elements are located is shown in formula (1), then the normal vector of the plane where the three antenna elements are located is (A, B, C). The direction information includes: (A, B, C). Or, the direction information includes: A, B, C.

[0185] In implementation 1.5, the directional information is represented by the orientation of the linear array corresponding to the multiple arrays. In other words, the orientation of the linear array corresponding to the multiple arrays can be used to characterize the directional information. This implementation can be applied to the case where multiple antenna arrays can form a linear array, or an approximate linear array. In addition, the embodiment of the present application does not limit the specific form of using the orientation of the linear array corresponding to the multiple arrays to represent the directional information. For example, in the directional information, the orientation of the linear array corresponding to the multiple arrays is represented in the form of a vector or a numerical value.

For the specific description of the second information, please refer to the above-mentioned related description, which will not be repeated here.

[0218] Optionally, the terminal device determines the rotation relationship between the first coordinate system and the second coordinate system based on the first information and the second information, including: the terminal device determines the coordinates of at least one of the multiple antenna arrays in the first coordinate system at the second moment based on the first information and the second information; the terminal device determines the rotation relationship between the first coordinate system and the second coordinate system based on the coordinates of at least one of the multiple antenna arrays in the first coordinate system at the second moment, and the coordinates of at least one of the multiple antenna arrays in the first coordinate system at the first moment. For the specific description of the operation of the terminal device determining the coordinates of at least one of the multiple antenna arrays in the first coordinate system at the second moment based on the first information and the second information, please refer to the aforementioned related description, which will not be repeated here.

[0219] Exemplarily, taking the case where the multiple antenna arrays of the terminal device are 3 antenna arrays, the terminal device has determined that the coordinates of antenna array #1 in the first coordinate system at the second moment are (x1, y1, z1), the coordinates of antenna array #2 in the first coordinate system at the second moment are (x2, y2, z2), and the coordinates of antenna array #3 in the first coordinate system at the second moment are (x3, y3, z3). In addition, the coordinates of antenna array #1 in the first coordinate system at the first moment are (a1, b1, c1), the coordinates of antenna array #2 in the first coordinate system at the second moment are (a2, b2, c2), and the coordinates of antenna array #3 in the first coordinate system at the second moment are (a3, b3, c3).

The rotation matrix R of the second coordinate system relative to the first coordinate system satisfies formulas (21) to (23).

[0221]

[0222]

[0223]

[0224] Based on formula (21) to formula (23), it can be determined that R satisfies formula (24).

[0225]

[0226] In addition, R also satisfies formula (25).

[0227]

[0228] Where cos is the cosine function, and sin is the sine function. α, β, and γ are the rotation angles of the second coordinate system relative to the first coordinate system. For details, please refer to the relevant explanation in Implementation 1.1, which will not be repeated here. Then, based on formula (24) and formula (25), the values ​​of α, β, and γ can be determined, and then the rotation relationship of the second coordinate system relative to the first coordinate system can be determined.

[0229] For example, the multiple antenna arrays of the terminal device are 3 antenna arrays, and antenna array #1 among the 3 antenna arrays is used as the reference point of the terminal device. The first coordinate system consists of an x-axis, a y-axis, and a z-axis. Fig.10 , at the first moment, the coordinates of antenna element #1 in the first coordinate system are (0, 0, 0), the coordinates of antenna element #2 in the first coordinate system are (1, 0, 0), and the coordinates of antenna element #3 in the first coordinate system are (0, 1, 0). The terminal device rotates from the first moment to the second moment, causing the orientation of the terminal device to change. At the second moment, the coordinates of antenna element #1 in the first coordinate system are (x1, y1, z1), the coordinates of antenna element #2 in the first coordinate system are (x2, y2, z2), and the coordinates of antenna element #3 in the first coordinate system are (x3, y3, z3).

[0233] β=arcsin(z1-z2) (28)

[0234]

[0235] Among them, cos is the cosine function and arcsin is the inverse sine function.

[0236] In addition, the rotation relationship between the first coordinate system and the second coordinate system may be determined based on other methods besides being determined based on the first information and the second information, and the embodiment of the present application does not limit this.

[0237] In implementation 2.2, the terminal device determines direction information, including: the terminal device determines normal vectors of the planes where the multiple antenna arrays are located, and uses the normal vectors of the planes where the multiple antenna arrays are located to represent the direction information. The normal vector represents a vector perpendicular to the plane where the antenna arrays are located.

[0238] Optionally, the normal vectors of the planes where the multiple antenna arrays are located are determined based on the first information and the second information, and the second information is used to indicate the relative position relationship of the multiple antenna arrays. For the specific description of the second information, please refer to the above-mentioned related description, which will not be repeated here.

[0239] Optionally, the terminal device determines the normal vector of the plane where the multiple antenna arrays are located based on the first information and the second information, including: the terminal device determines the coordinates of at least one antenna array among the multiple antenna arrays in the first coordinate system based on the first information and the second information; the terminal device determines the normal vector of the plane where the multiple antenna arrays are located based on the coordinates of at least one antenna array among the multiple antenna arrays in the first coordinate system. For a specific description of the operation of the terminal device determining the coordinates of at least one antenna array among the multiple antenna arrays in the first coordinate system based on the first information and the second information, please refer to the aforementioned related description, which will not be repeated here.

[0240] For example, the terminal device has three antenna arrays as the multiple antenna arrays, and the coordinates of the three antenna arrays in the first coordinate system are (x1, y1, z1), (x2, y2, z2), and (x3, y3, z3). Assume that the normal vectors of the planes where the three antenna arrays are located are (A, B, C), and A, B, and C satisfy formulas (30) to (32).

[0241] A(x2-x1)+B(y2-y1)+C(z2-z1)=0 (30)

[0242] A(x3-x1)+B(y3-y1)+C(z3-z1)=0 (31)

[0243] A(x3-x2)+B(y3-y2)+C(z3-z2)=0 (32)

[0244] By jointly solving formula (30) to formula (32), the values ​​of A, B, and C can be determined, and thus the normal vectors of the planes where the three antenna elements are located in the first coordinate system can be determined.

[0245] In addition, the normal vector of the plane where the multiple antenna elements are located can be determined based on other methods besides the first information and the second information, and the embodiments of the present application are not limited to this.

[0246] In implementation 2.3, the terminal device determines the direction information, including: the terminal device determines the plane where the multiple antenna arrays are located, and uses the plane where the multiple antenna arrays are located to represent the direction information. Optionally, the method also includes: the terminal device sends plane information to the positioning device or the network device, the plane information is used to indicate the plane where the multiple antenna arrays are located, and the plane information represents the direction information.

[0248] Optionally, the terminal device determines the planes where the multiple antenna arrays are located based on the first information and the second information, including: the terminal device determines the coordinates of at least one antenna array among the multiple antenna arrays in the first coordinate system based on the first information and the second information; the terminal device determines the planes where the multiple antenna arrays are located based on the coordinates of at least one antenna array among the multiple antenna arrays in the first coordinate system. For a specific description of the operation of the terminal device determining the coordinates of at least one antenna array among the multiple antenna arrays in the first coordinate system based on the first information and the second information, please refer to the aforementioned related description, which will not be repeated here.

[0249] Exemplarily, taking the case where the multiple antenna arrays of the terminal device are three antenna arrays, the coordinates of the three antenna arrays in the first coordinate system are (x1, y1, z1), (x2, y2, z2), and (x3, y3, z3). Based on formulas (30) to (32), the normal vectors (A, B, C) of the plane where the three antenna arrays are located in the first coordinate system can be determined. Assume that in the first coordinate system, the plane equation corresponding to the plane where the three antenna arrays are located is Ax+By+Cz+D=0; by substituting any coordinate of (x1, y1, z1), (x2, y2, z2), and (x3, y3, z3) into Ax+By+Cz+D=0, the value of D can be determined, and then the plane equation corresponding to the plane where the three antenna arrays are located can be determined.

[0250] In addition, the plane where the multiple antenna elements are located can be determined based on other methods in addition to the first information and the second information, and the embodiments of the present application are not limited to this.

[0251] In implementation 2.4, the terminal device determines direction information, including: the terminal device determines the direction of the linear array corresponding to the multiple arrays, and uses the direction corresponding to the multiple arrays to represent the direction information. This implementation can be applied to the case where multiple antenna arrays form a linear array, or a linear array approximation.

[0252] Optionally, the directions of the linear arrays corresponding to the multiple arrays are determined based on the first information and the second information, and the second information is used to indicate the relative position relationship of the multiple antenna arrays. For the specific description of the second information, please refer to the above-mentioned related description, which will not be repeated here.

[0253] Optionally, the terminal device determines the orientation of the linear arrays corresponding to the multiple arrays based on the first information and the second information, including: the terminal device determines the coordinates of at least one antenna array among the multiple antenna arrays in the first coordinate system based on the first information and the second information; the terminal device determines the orientation of the linear arrays corresponding to the multiple arrays based on the coordinates of at least one antenna array among the multiple antenna arrays in the first coordinate system. For a specific description of the operation of the terminal device determining the coordinates of at least one antenna array among the multiple antenna arrays in the first coordinate system based on the first information and the second information, please refer to the above-mentioned related description, which will not be repeated here.

[0254] For example, if the multiple antenna arrays of the terminal device are two antenna arrays, the coordinates of one of the two antenna arrays are (x1, y1, z1), and the coordinates of the other antenna array are (x2, y2, z2). The vectors are used to represent the direction of the linear arrays corresponding to the two antenna arrays: (x1-x2, y1-y2, z1-z2) or (x2-x1, y2-y1, z2-z1).

[0255] In addition, the directions of the linear arrays corresponding to the multiple arrays may be determined based on other methods besides the first information and the second information, and the embodiments of the present application do not limit this.

[0256] In an optional implementation, the method further includes: the terminal device receives first request information, and the first request information is used to request the terminal device to report direction information. In an optional manner, for the case where the positioning device is independent of the network device, the first request information may be sent directly from the positioning device to the terminal device; or, the first request information may also be sent from the positioning device to the terminal device through other devices (for example, a network device that provides services for the terminal device). In another optional manner, for the case where the positioning device is integrated in the network device, the first request information is sent from the network device that provides services for the terminal device to the terminal device.

[0257] In an optional implementation, the terminal device sends the direction information of the terminal device, including: the terminal device sends one or more direction information. In the case where the terminal device sends one direction information, the direction information is obtained based on the measurement of the first reference signal received through multiple antenna elements. It is understandable that after receiving the first reference signal, the terminal device can perform the operation of determining the direction information based on the first information obtained by measuring the first reference signal received this time, and sending the direction information.

[0258] For example, at time #1, the terminal device receives the first reference signal #1 through multiple antenna elements, measures the first reference signal #1 to obtain the first information #1, determines the direction information #1 based on the first information #1, and sends the direction information #1. At time #2, the terminal device receives the first reference signal #2 through multiple antenna elements, measures the first reference signal #2 to obtain the first information #2, determines the direction information #2 based on the first information #2, and sends the direction information #2. At time #3, the terminal device receives the first reference signal #3 through multiple antenna elements, measures the first reference signal #3 to obtain the first information #3, determines the direction information #3 based on the first information #2, and sends the direction information #3. Among them, time #1 is earlier than time #2, and time #2 is earlier than time #3.

[0259] In addition, in the case where the terminal device sends multiple direction information, the multiple direction information corresponds to multiple first information one by one, the direction information is determined based on the first information corresponding to the direction information, and the multiple first information is obtained by measuring the first reference signal received multiple times through multiple antenna elements. It is understandable that after receiving the first reference signal, the terminal device can perform the operation of determining the direction information based on the first information obtained by measuring the first reference signal received this time, and send multiple direction information after a period of time or after a predefined number of signal receptions.

[0260] For example, at time #1, the terminal device receives the first reference signal #1 through multiple antenna arrays, measures the first reference signal #1 to obtain the first information #1, and determines the direction information #1 based on the first information #1. At time #2, the terminal device receives the first reference signal #2 through multiple antenna arrays, measures the first reference signal #2 to obtain the first information #2, and determines the direction information #2 based on the first information #2. At time #3, the terminal device receives the first reference signal #3 through multiple antenna arrays, measures the first reference signal #3 to obtain the first information #3, and determines the direction information #3 based on the first information #2. The terminal device sends direction information #1, direction information #2, and direction information #3 at time #4. Among them, time #1 is earlier than time #2, time #2 is earlier than time #3, and time #3 is earlier than time #4.

[0261] Taking the positioning device being independent of the network device as an example, an exemplary information transmission method is provided below. Fig.11As shown, the exemplary information transmission method includes: the positioning device and the network device interact with each other with configuration information, for example, the configuration information is used to configure the first reference signal, and the configuration information includes the location of the network device, etc. The positioning device sends a third request information to the terminal device, and the third request information is used to request the terminal device to report the capability related to direction measurement. The terminal device sends a response information to the positioning device, and the response information is used to indicate the capability related to direction measurement possessed by the terminal device. The terminal device receives the first reference signal sent by the network device through multiple antenna elements. The terminal device measures the first reference signal to obtain the first information. The terminal device determines the direction information of the terminal device based on the first information. The positioning device sends a first request information to the terminal device, and the first request information is used to request the terminal device to report the direction information. The terminal device sends the direction information to the positioning device. Thus, the positioning device can send the location and direction information of the terminal device to the network device, and then the network device can distribute the corresponding video content or perform business-related operations based on the location and direction information of the terminal device.

[0262] In summary, in the information transmission method 100, the terminal device receives the first reference signal through multiple antenna elements; the terminal device sends the direction information of the terminal device, and the direction information is determined based on the first information, and the first information is obtained by measuring the first reference signal. It can be seen that the method determines the direction information of the terminal device, which is conducive to enhancing the positioning function and providing a capability base for services based on the direction of the terminal device (for example, AR / VR / MR video and other services), thereby supporting services based on the direction of the terminal device.

[0263] In addition, the direction information of the terminal device determined based on this method can also be used in combination with the position of the terminal device (for example, the three-dimensional coordinates of the terminal device) to meet the business's positioning requirements for the terminal device and improve business quality.

[0264] In addition, the terminal device determines the direction information based on the first information obtained by measuring the first reference signal, which reduces the terminal device's dependence on sensors and reduces the complexity of hardware in the terminal device.

[0265] See also Fig.12 , Fig.12 It is a flow chart of an information transmission method 200 provided in an embodiment of the present application. The information transmission method 200 includes the following steps.

[0266] S201. A network device sends a first reference signal. Correspondingly, a terminal device receives the first reference signal through multiple antenna elements.

[0267] S202: The terminal device sends first information and second information, wherein the first information is obtained by measuring a first reference signal, and the second information is used to indicate the relative position relationship of multiple antenna arrays. Correspondingly, the positioning device receives the first information and the second information.

[0268] S203: The positioning device determines direction information of the terminal device based on the first information and the second information.

[0269] The difference between information transmission method 200 and information transmission method 100 is that: in information transmission method 100, after the terminal device measures the first reference signal to obtain the first information, it determines the direction information of the terminal device based on the first information and sends the direction information of the terminal device; while in information transmission method 200, after the terminal device measures the first reference signal to obtain the first information, it sends the first information, and the positioning device determines the direction information of the terminal device based on the first information and the second information.

[0270] In addition, the operation of the positioning device determining the direction information of the terminal device is similar to the operation of the terminal device determining the direction information of the terminal device in the information transmission method 100. For a specific description, reference may be made to the relevant description in the information transmission method 100, which will not be repeated here. For a specific description of the information transmission method 200, reference may be made to the relevant description in the information transmission method 100, which will not be repeated here.

[0271] in addition, Fig.12 The case where the positioning device is independent of the network device is used for illustration. In this case, the first information and the second information can be sent directly by the terminal device to the positioning device; or, the first information and the second information can also be sent by the terminal device to the positioning device through other devices (for example, a network device that provides services for the terminal device).

[0272] Apart from Fig.12 In addition to the case where the positioning device is independent of the network device as shown in the figure, the positioning device can also be integrated in the network device. In this case, the first information and the second information are sent by the terminal device to the network device that provides services for the terminal device.

[0296] The following takes the positioning device being independent of the network device as an example to provide an exemplary information transmission method. Fig.15 As shown, the exemplary information transmission method includes: the positioning device sends a third request message to the terminal device, and the third request message is used to request the terminal device to report capabilities related to direction measurement. The terminal device sends a response message to the positioning device, and the response message is used to indicate the capabilities related to direction measurement possessed by the terminal device. The response message includes second information, and the second information is used to indicate the relative position relationship of multiple antenna arrays. The positioning device sends a fourth request message to the network device, and the fourth request message is used to request the network device to configure a second reference signal, and the fourth information includes the second information. The network device sends a third message to the terminal device, and the third information is used to configure the second reference signal, and the third information is determined based on the second information. Based on the third information, the terminal device sends the second reference signal through multiple antenna arrays. The network device determines the direction information of the terminal device based on the first information obtained by measuring the second reference signal, and sends the direction information to the positioning device.

[0297] Optionally, in the case where multiple network devices receive the second reference signal, the network device that provides services for the terminal device among the multiple network devices sends the third information to the positioning device in addition to sending the third information to the terminal device. The positioning device sends the third information to other network devices among the multiple network devices except the network device that provides services for the terminal device, which is conducive to the other network devices receiving the second reference signal based on the third information. The other network devices determine the first information based on the received second reference signal, and send the first information to the network device that provides services for the terminal device. The network device determines the direction information of the terminal device based on the first information, including: the network device that serves the terminal device determines the direction information of the terminal device based on the first information determined by each of the multiple network devices.

[0298] In summary, the information transmission method 300 determines the direction information of the terminal device, which is conducive to enhancing the positioning function and providing a capability base for services based on the direction of the terminal device (for example, AR / VR / MR video services, etc.), thereby supporting services based on the direction of the terminal device. In addition, the direction information of the terminal device determined based on the method can also be used in combination with the position of the terminal device (for example, the three-dimensional coordinates of the terminal device), so as to meet the business's positioning requirements for the terminal device and improve the quality of the service.

[0299] In view of the fact that the positioning device is independent of the network device, the embodiment of the present application further provides an information transmission method 400. Fig.16 , Fig.16 It is a flow chart of an information transmission method 400 provided in an embodiment of the present application. The information transmission method 400 includes the following steps.

[0300] S401. The terminal device sends a second reference signal through multiple antenna elements; correspondingly, the network device receives the second reference signal.

[0301] S402: The network device sends first information, where the first information is obtained by measuring the second reference signal. Correspondingly, the positioning device receives the first information.

[0303] S404: The positioning device determines direction information of the terminal device based on the first information and the second information.

[0304] The difference between information transmission method 400 and information transmission method 300 is that: in information transmission method 300, after the network device measures the second reference signal to obtain the first information, the network device determines the direction information of the terminal device based on the first information; while in information transmission method 400, after the network device measures the second reference signal to obtain the first information, it sends the first information, and the positioning device determines the direction information of the terminal device based on the first information and the second information.

[0305] In addition, the operation of the positioning device determining the direction information of the terminal device based on the first information and the second information is similar to the operation of the terminal device determining the direction information of the terminal device based on the first information and the second information in the information transmission method 100. For a specific description, reference may be made to the relevant description in the information transmission method 100, which will not be repeated here. For a specific description of the information transmission method 400, reference may be made to the relevant description in the information transmission method 300, which will not be repeated here.

[0306] An exemplary information transmission method is provided below: Fig.17 As shown in Fig.17 As shown in the dashed box, Fig.17 The information transmission method shown is similar to Fig.15The difference between the information transmission methods shown is that: after the network device measures the second reference signal to obtain the first information, it does not perform the operation of determining the direction information of the terminal device based on the first information, but performs the operation of sending the first information to the positioning device, and then the positioning device determines the direction information of the terminal device based on the first information. Optionally, in the case where multiple network devices receive the second reference signal, after the multiple network devices respectively measure the second reference signal to obtain the first information, they send the first information to the positioning device; the positioning device determines the direction information of the terminal device based on the first information respectively sent by the multiple network devices.

[0307] In summary, the information transmission method 400 determines the direction information of the terminal device, which is conducive to enhancing the positioning function and providing a capability base for services based on the direction of the terminal device (for example, AR / VR / MR video services, etc.), thereby supporting services based on the direction of the terminal device. In addition, the direction information of the terminal device determined based on the method can also be used in combination with the position of the terminal device (for example, the three-dimensional coordinates of the terminal device), so as to meet the positioning requirements of the business for the terminal device and improve the quality of the service.

[0308] In another embodiment, the information transmission method provided in the embodiment of the present application can also be applied to the side chain communication scenario. In this scenario, the "terminal device" in the aforementioned information transmission method can be replaced with: the first terminal device, and the "network device" in the aforementioned information transmission method can be replaced with: the second terminal device. The information transmission method in this scenario is similar to the aforementioned information transmission method and will not be described in detail.

[0309] Exemplarily, the information transmission method includes: a first terminal device sends a third reference signal through multiple antenna elements; correspondingly, a second terminal device receives the third reference signal. The second terminal device determines direction information of the first terminal device, the direction information is determined based on first information, and the first information is obtained by measuring the third reference signal.

[0310] Exemplarily, the information transmission method includes: the second terminal device sends a fourth reference signal; correspondingly, the first terminal device receives the fourth reference signal through multiple antenna elements. The first terminal device determines the direction information of the first terminal device, the direction information is determined based on the first information, and the first information is obtained by measuring the fourth reference signal.

[0311] Optionally, the third reference signal or the fourth reference signal is SL-PRS. However, the embodiment of the present application does not limit the types of the third reference signal and the fourth reference signal, which may be other signals used for positioning and sidelink transmission in addition to SL-PRS.

[0312] Optionally, after the second terminal device or the first terminal device determines the direction information of the first terminal device, it can also send the direction information of the first terminal device to the positioning device. This is beneficial for the positioning device to distribute video content or perform business-related operations for the first terminal device based on the direction information of the first terminal device. Optionally, the second terminal device or the first terminal device directly sends the direction information of the first terminal device to the positioning device; or, the second terminal device or the first terminal device sends the direction information of the first terminal device to the positioning device through other network elements.

[0313] In summary, the method determines the direction information of the terminal device, which is conducive to enhancing the positioning function and providing a capability base for services based on the orientation of the terminal device (for example, AR / VR / MR video services, etc.), thereby supporting services based on the orientation of the terminal device. In addition, the direction information of the terminal device determined based on the method can also be used in combination with the position of the terminal device (for example, the three-dimensional coordinates of the terminal device) to meet the positioning requirements of the terminal device and improve the quality of the service. In addition, determining the direction information based on the reference signal received or sent by the terminal device through multiple antenna arrays reduces the terminal device's dependence on sensors and reduces the complexity of the hardware in the terminal device.
