Description

Technical Field

[0001] The present application relates to the field of communication technology, and in particular to a beam direction determination method, apparatus, device, and medium. Background Art

[0002] The fundamental concept of Integrated Sensing and Communication (ISAC) is to introduce wireless sensing capabilities into wireless mobile communications. Wireless sensing involves sensing environmental information through wireless signals. This information includes the distribution, size, quantity, and temperature of objects in the environment, human movements and behavior, and even breathing and heart rates. Wireless sensing works by transmitting a sensing signal to the environment / target object to be sensed. This signal, after being reflected or scattered by the sensed objects in the environment, reaches the receiver. After complex signal processing, the environmental characteristics are detected and the perceived environment is reconstructed on the device. This includes identifying people and objects in the environment, detecting temperature, human movements, and even breathing and heart rates.

[0003] Currently, the optimal direction for receiving sensing signals is the non-line-of-sight (NLOS) path, which is the path after reflection from the sensing object. However, the optimal direction for communication is typically the line-of-sight (LOS) path, which is the visible path from the base station to the terminal. This makes it difficult to establish a quasi-co-located (QCL) relationship between communication and sensing signals. This can be understood as the same quasi-co-located relationship, where the transmission beam direction is the same. Furthermore, the receiving beam direction corresponding to the sensing signal is strongly correlated with the position of the sensing object, but the position of the sensing object is random, resulting in a lack of available reference signals. Therefore, determining the receiving beam direction corresponding to the sensing signal becomes a challenge that needs to be addressed.

[0004] When transmitting sensing signals, the target object is the object being sensed. However, these objects are distributed over a wider area than the communication nodes, making it impossible to use existing communication reference signals as the QCL relationship. To prevent interference between adjacent sensing nodes, the technical challenge of indicating the corresponding transmission beam direction for the sensing signal remains unsolved.

[0123] In the embodiments of this application, the term "and / or" describes the association relationship between associated objects, indicating that three relationships can exist. For example, A and / or B can represent three situations: A exists alone, A and B exist simultaneously, and B exists alone. The character " / " generally indicates that the associated objects are in an "or" relationship.

[0124] In the embodiments of the present application, the term "plurality" refers to two or more than two, and other quantifiers are similar.

[0125] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0126] In order to facilitate understanding of the solution of this application, the relevant contents involved in this application are first introduced.

[0127] Wireless sensing is generally divided into: single-station sensing (monostatic) and dual-station sensing (bistatic). Single-station sensing is when a sensing node, such as a base station (or terminal), actively sends a sensing signal. After the sensing signal is reflected by the sensed object, the sensing node, such as the base station (or terminal), receives the reflected sensing signal. Figure 1 (a) gNB single-base perception and (b) UE single-base perception.

[0128] Dual-station refers to a sensing node such as a base station (or terminal) actively sending a sensing signal, which is then received by another sensing node such as a terminal (or base station) via a wireless channel. Figure 1 (c) UE-gNB dual-base sensing, (d) gNB-UE dual-base sensing, (e) UE-UE dual-base sensing, and (f) gNB-gNB dual-base sensing.

[0129] For the receiving end of the sensing signal, in order to receive the signal reflected by the sensing target, how to indicate the receiving beam direction corresponding to the sensing signal reflected by the sensing target is a technical problem that needs to be solved. Figure 2 The base station transmits a sensing signal at an angle α. After passing through the perceived object, it is reflected at a directional angle β to the receiving UE (which can also be the base station). For the receiving UE, if the signal (the signal reflected by the perceived object) is received according to the directional angle β, the signal-to-noise ratio (SNR) of the received signal will be improved, thus enhancing sensing performance. Conversely, if the UE's receiving beam angle differs significantly from β, not only will sensing performance be degraded, but it may even lead to sensing errors.

[0130] Existing communication QCL indication methods: Assume that a base station is about to send a reference signal RS-1 to a terminal. The base station uses QCL parameters to instruct the UE how to receive RS-1. Specifically, the QCL parameters associate RS-1 with a reference signal RS-0. RS-0 is the beam direction determined by the terminal through beam scanning, which is relatively stable. The receive beam direction of RS-1 adopts the same direction as RS-0.

[0131] The aforementioned QCL indication method has limitations for sensing signal reception. The optimal receiving direction for sensing signals is the NLOS path, which is the path after reflection from the sensing object. However, the optimal receiving direction for communication is the LOS path, which is the line-of-sight path from the base station to the terminal. This makes it difficult to establish a QCL relationship between the communication signal and the sensing signal. Furthermore, the receiving beam direction corresponding to the sensing signal is strongly correlated with the position of the sensing object, but the position of the sensing object is random, resulting in a lack of a usable reference signal. Therefore, determining the receiving beam direction corresponding to the sensing signal becomes a challenge that needs to be addressed.

[0132] For the transmitter of the sensing signal, in order to avoid mutual interference between adjacent sensing nodes, how to indicate the transmission beam direction corresponding to the sensing signal is a technical problem that needs to be solved. Figure 3 , UE and base station both use single-base transmission mode. For the single-base mode of the same node, the receiving beam direction is the same as the transmitting direction. To improve spectrum utilization, the resources used by different transmitting nodes need to be coordinated (for example, when there is mutual interference, the transmission resources of the two nodes are orthogonal; when there is no mutual interference, the same resources can be used). The following two scenarios:

[0133] Figure 3 In scenarios 1 and 2, the sending directions of the two nodes deviate from the receiving direction angle of each other, so there is no interference between them and they can use the same resources.

[0134] Figure 3 In scenarios 3 and 4, the sending directions of the two nodes are close to the receiving direction angle of the other party, which will cause mutual interference.

[0135] In summary, in certain sensing resource situations, it is necessary to indicate the transmission beam direction. If the direction is indicated randomly, serious interference problems will occur.

[0136] Existing QCL indication methods for communications: Assume that a base station is preparing to have a UE transmit a reference signal, RS-1. The base station uses QCL parameters to instruct the UE on how to transmit RS-1. Specifically, the QCL parameters associate RS-1 with a reference signal, RS-0, where RS-0 represents the beam direction determined by the UE through beam scanning.

[0137] If RS-0 is a downlink reference signal, the UE uses uplink and downlink reciprocity to determine to send the reference signal RS-1 in a beam direction opposite to that of RS-0.

[0138] If RS-0 is an uplink reference signal, the UE transmits the reference signal RS-1 using the same beam direction as RS-0.

[0139] The above QCL indication method has limitations for the transmission of sensing signals. The reason is that the target object is the sensed object, and the distribution range of the sensed object is wider than the distribution range of the communication nodes, which makes it impossible to use the communication reference signal directly as the QCL relationship. For example:

[0140] When the UE sends a communication signal, its target base station has only one direction; when the UE sends a perception signal, there will be multiple directions due to the randomness of the location of the perceived object.

[0141] When the base station sends a sensing signal, for low-altitude aircraft (such as drones), the sensed targets are mainly in the sky, which is completely different from the direction of UEs distributed on the ground.

[0142] Therefore, for the transmission of sensing signals, in order to avoid mutual interference between adjacent sensing nodes, how to indicate the transmission beam direction corresponding to the sensing signal is also a technical problem that needs to be solved.

[0143] In order to solve the above technical problems, the embodiments of the present application provide a beam direction determination method, device, equipment and medium, wherein the method and device are based on the same application concept. Since the principles of solving the problems by the method and device are similar, the implementation of the device and method can refer to each other, and the repeated parts will not be repeated.

[0144] Since the embodiments of the present application involve sensing the position of a target, in order to facilitate subsequent understanding of the solution of the present application, the position of an object in three-dimensional space is first introduced.

[0145] Generally, the position of an object in three-dimensional space can be expressed using three-dimensional coordinates (X, Y, Z) or polar coordinates. Figure 4 .

[0146] For the above x, y, z coordinates, x, y are horizontal planes, and z is the vertical axis. Define the azimuth angle A ( Figure 4 φ in ). Pitch angle Z (zenith angle Z, such as Figure 4 For ease of understanding, the following definitions can be used:

[0147] When the pitch angle Z is equal to 0 degrees, it points to the vertical plane (towards the sky); when Z is equal to 90 degrees, it points to the horizontal plane; when Z is equal to 180 degrees, it points to the center of the earth.

[0148] When the azimuth angle A is equal to 0 degrees, it points to the north; when it is equal to 90 degrees, it points to the east; when it is equal to 180 degrees, it points to the south.

[0149] It should be noted that the definition of the pitch angle Z is: when the pitch angle Z is equal to 90 degrees, it points to the vertical plane (towards the sky); when Z is equal to 0 degrees, it points to the horizontal plane; when Z is equal to -90 degrees, it points to the center of the earth. Accordingly, the description of the embodiments of this application needs to be modified accordingly, such as converting cosθ to sinθ.

[0150] like Figure 5 As shown, it is a flow chart of the beam direction determination method provided in an embodiment of the present application. The method is executed by the indicated device. Optionally, the indicated device is a base station or a terminal.

[0151] Step 501: receiving indication information sent by an indication device, where the indication information includes first indication information or second indication information, where the first indication information is used to indicate a direction of a transmitting beam or a direction of a receiving beam, and the second indication information is used to determine a position of a sensing target;

[0152] Here, the pointing device, the pointed device, and the perception target may be located in the same perception environment.

[0153] Optionally, the indicating device is a perception server (also called a perception signal configuration node), a base station or a terminal.

[0154] Here, the indicated device receives the indication information sent by the indicating device. Specifically, the base station may receive the indication information sent by the perception server, or the terminal may receive the indication information sent by the perception server, or the terminal may receive the indication information sent by the base station, or one terminal may receive the indication information sent by another terminal, or one base station may receive the indication information sent by another base station.

[0155] It should be understood that the first indication information is an explicit indication (direct indication), indicating the direction information of the transmitting beam or the direction information of the receiving beam, such as indicating the direction information of the transmitting beam corresponding to the perception information to be sent (such as the perception signal or the perception data), or indicating the direction of the reflection beam of the perception information, that is, the direction information of the receiving beam corresponding to the perception information at the receiving end.

[0156] The second indication information is an implicit indication. The location of the sensing target is determined by the second indication information, and then the beam sending direction or beam receiving direction corresponding to the sensing signal is determined according to the location of the sensing target. It should be understood that the location of the sensing target is the location of a preset sensing target. The preset here can be understood as follows: the indicating device (as a detection node) assumes that the sensing target may appear at a certain location, such as dividing the sensing area into a certain number of small areas, and each beam direction can cover a small area. When the indicated device (as a sensing node) performs a scan of all small areas, each small area is the location of the preset sensing target.

[0157] In some embodiments, step 501 includes:

[0158] The indication information sent by the indication device is received through target data, high-layer signaling or a physical layer control channel.

[0159] Optionally, the target data is perception-assisted data. Optionally, the high-layer signaling is implemented by radio resource control (RRC) or media access control element (MAC-CE) or other interface signaling between different devices.

[0160] Step 502: Determine a beam sending direction or a beam receiving direction corresponding to the perception information according to the indication information.

[0161] Here, if the indication information is the first indication information, the direct indication of the first indication information is used to determine the beam sending direction or beam receiving direction corresponding to the perception information; if the indication information is the second indication information, the indirect indication of the second indication information is used to determine the position of the perception target; then, based on the position of the perception target, the beam sending direction or beam receiving direction corresponding to the perception information is determined.

[0162] That is, by implementing the method of the embodiment of the present application, firstly, the indicated device can determine the sending beam direction corresponding to the perception information to be sent based on the above-mentioned indication information, solve the problem of how to indicate the sending beam direction corresponding to the perception signal, and avoid mutual interference between adjacent perception nodes; secondly, the indicated device can determine the receiving beam direction corresponding to the perception information based on the above-mentioned indication information, solve the problem of how to indicate the receiving beam direction corresponding to the perception signal, and improve the transmission efficiency of the perception signal.

[0163] Optionally, the first indication information includes a direction angle, and the direction angle includes one of the following:

[0164] The direction angle of the transmission beam corresponding to the sensing information;

[0165] The direction angle of the receiving beam corresponding to the sensing information;

[0166] The offset angle relative to the transmit beam direction indicated by the quasi-co-located QCL parameters;

[0167] The offset angle relative to the transmit beam direction indicated by the QCL parameters.

[0168] The direction angle includes the azimuth angle A and / or the elevation angle Z.

[0169] It should be understood that the first indication information indicates an absolute direction angle, that is, the direction angle of the transmission beam corresponding to the perception information, see Figure 6 ; or indicates the direction angle of the receiving beam corresponding to the perception information; or the first indication information indicates an angular offset based on the QCL parameter, that is, indicates the offset angle γ relative to the receiving beam direction indicated by the QCL, see Figure 7 ; or indicates the offset angle γ relative to the transmit beam direction indicated by the QCL.

[0170] The first indication information is mainly used to indicate the direction of the transmission beam. The indicated transmission beam direction can be understood as the direction in which the target is detected (instructing the base station or terminal to send a beam to test whether the target exists).

[0171] Case 1: The first indication information includes a direction angle, and the direction angle is the direction angle of a transmitting beam corresponding to the perception information; or the direction angle of a receiving beam corresponding to the perception information.

[0172] In case 2, the first indication information includes a direction angle, and the direction angle is an offset angle γ relative to the transmitting beam direction indicated by the QCL parameter; or the direction angle is an offset angle γ relative to the receiving beam direction indicated by the QCL parameter. The offset angle γ may include an azimuth angle A and / or an elevation angle Z. Here, the QCL parameter includes at least one reference signal RS, or a reference signal identifier RS-ID. In case 2, the transmitting beam direction or the receiving beam direction indicated by the first indication information is a direction corresponding to an angle γ offset from the beam direction corresponding to the reference signal RS.

[0173] It should be understood that the first indication information includes a first parameter (basic parameter value), which is the direction angle of the transmitting beam (or receiving beam) corresponding to the perception information, or the first parameter is the offset angle γ relative to the transmitting beam (or receiving beam) direction indicated by the QCL parameter.

[0174] As can be seen from the above, the direction angle includes the azimuth angle A and / or the elevation angle Z. Accordingly, the first parameter includes: the A angle parameter (e.g., 0-359 degrees, with a default indication resolution of 1 degree) and the Z angle parameter (e.g., 0-180 degrees, with a default indication resolution of 1 degree). Optionally, the resolution of the indication value defaults to 1 degree, or is determined according to the protocol agreement or configuration.

[0175] The indication ranges of the above-mentioned A angle and Z angle can use the above-mentioned default ranges, or can be set according to protocol agreement or configuration (such as setting maximum and minimum values according to scene configuration). If the sensing target is above the sensing node (the indicated device), the Z angle range can be -90 degrees to 90 degrees (such as adding a configuration offset offset = -90); if the sensing target is close to the ground, the Z angle range can be 90 degrees to 180 degrees (such as adding a configuration offset offset = 90).

[0176] For example, if the Z angle is configured as Z=80 and the offset is configured as -50, the actual indication is Z=80-50=30 degrees.

[0177] Optionally, the first indication information further includes one or more of the following:

[0178] The offset of the direction angle;

[0179] The first range indication of the directional angle is used to indicate that the value range of the directional angle is increased; here, this parameter indicates that the direction of the transmit beam (or receive beam) corresponding to the perception information can be further relaxed. Optionally, the first range indication of the directional angle includes a first range indication of the A angle and / or a first range indication of the Z angle.

[0180] The second range indication of the directional angle is used to indicate that the value range of the directional angle is reduced; here, this parameter indicates that the direction of the transmit beam (or receive beam) corresponding to the perception information can be further tightened. Optionally, the second range indication refine of the directional angle includes a second range indication of the A angle and / or a second range indication of the Z angle.

[0181] That is, the first indication information includes not only the first parameter but also the second parameter and / or the third parameter.

[0182] The second parameter includes a first range indication range of the angle A (ie, a larger range value range of the angle A) or a second range indication refine of the angle A (ie, a fine value refine of the angle A).

[0183] The third parameter includes a first range indication range of the Z angle (ie, a larger range value range of the Z angle) or a second range indication refine of the Z angle (ie, a fine value refine of the Z angle).

[0184] It should be noted that the first range indication or the second range indication can be configured separately for the A angle, or this parameter can be left unset, without any limitation here. The first range indication or the second range indication can be configured separately for the Z angle, or this parameter can be left unset, without any limitation here.

[0185] Here, the second parameter further expands the indication resolution of the A angle parameter in the first parameter, that is, increases or decreases the value range of the A angle.

[0186] The third parameter further expands the indication resolution of the Z angle parameter in the first parameter, that is, increases or decreases the value range of the Z angle.

[0187] Here, range means that the indicated resolution becomes larger, or the indicated range becomes larger (for example, from 1 degree to 4 degrees); refine means that the indicated resolution becomes smaller, or the indicated range becomes smaller (for example, from 1 degree to 0.2 degrees).

[0188] For the relationship between the first parameter and the second parameter, see Figure 8 Taking azimuth as an example, assuming the first parameter A is in degrees, 3 indicates an azimuth of 3 degrees, which means the azimuth angle A of the receiving or transmitting beam can be between 3.0 and 4.0 degrees.

[0189] If the second parameter indicates the first range of angle A (i.e., the larger range of values for angle A), it indicates that the angle A in the direction of the transmitting beam (or receiving beam) can be further relaxed. For example, if the second parameter indicates 2, it indicates that the value range of angle A in the direction of the transmitting beam (or receiving beam) can be from 3.0 degrees to 5.0 degrees.

[0190] If the second parameter indicates refinement of the second range of the A angle (i.e., refinement of the A angle value), it means that the A angle in the direction of the transmitting beam (or receiving beam) can be further tightened. For example, if the second parameter indicates 2 (each unit represents 0.2 degrees), it means that the value range of the A angle in the direction of the transmitting beam (or receiving beam) is: 3.4 degrees to 3.6 degrees.

[0191] It should be noted that when the second parameter is the first range indication range of angle A (i.e., the larger range value range of angle A), it is generally used to send beam instructions. For example, the perception server indicates to the base station so that the base station has the flexibility to determine the direction of the transmitted beam for coarse search. When the second parameter is the second range indication refine of angle A (i.e., the refine value of angle A), it is used to finely determine the perception target. For example, after the base station (the indicated device) perceives the position of the target through preliminary detection, it refines the perception position or speed.

[0192] The following uses the Z angle configuration as an example to illustrate how to configure the direction angle.

[0193] Z angle configuration parameters

[0194] {

[0195] Z angle value (e.g. 80) / / Note: The default angle is 1-180, with an indication accuracy of 1 degree;

[0196] Z angle offset (e.g. -90) / / Note: Optional configuration parameter, the offset relative to the indication range of 1-180, here changed to -90 to +90;

[0197] The first indication range of the Z angle range (e.g., 2) / / Note: Optional configuration parameter, the value range is 0 to 3. 0 represents 2 degrees, 1 represents 3 degrees, 2 represents 4 degrees, and 3 represents 5 degrees;

[0198] The second indication range of the Z angle is refined (e.g., 2). / / Note: This parameter is optional and has a value range of 0 to 3. 0 represents 0.2 degrees, 1 represents 0.4 degrees, 2 represents 0.6 degrees, and 3 represents 0.8 degrees.

[0199] Note: You can configure at most one of the range and refine options above.

[0200] }

[0201] Assuming the Z angle offset is configured above: the calculated Z angle is 80-90=-10 degrees.

[0202] When the above range is configured (to 2), it means that the Z angle value can be between -8 and -10.

[0203] When the refine setting is set to 2, the Z angle can be between -10.4 and -10.6.

[0204] It should be noted that the above offsets can be specified by the protocol to reduce protocol indication overhead, such as: the protocol configuration {offset-90, offset-45, offset0, offset45, offset90}, indicating one of them according to the service or scenario.

[0205] When indicating range or refine, you can use a bit to indicate which one to use.

[0206] The specific contents of the above range and refine instructions and the beam angle range can be achieved through configuration or the default protocol value.

[0207] The A angle can be set as the first range indicator or the second range indicator alone, or not set, and there is no limitation here. The Z angle can be set as the first range indicator or the second range indicator alone, or not set, and there is no limitation here.

[0208] For the above situation 2, that is, the first indication information includes a direction angle, which is an offset angle γ relative to the transmit beam direction indicated by the QCL parameter; or the direction angle is an offset angle γ relative to the receive beam direction indicated by the QCL parameter. For a more intuitive understanding, the transmit beam direction or receive beam direction is determined based on the indication information of situation 2. For details, please refer to Figure 9 and Figure 10 .

[0209] like Figure 9 As shown, the reference signal RS-1 between the gNB and the UE is a reference signal used for communication. The UE determines the receiving beam direction corresponding to the perception information based on the receiving beam direction and the offset angle γ of the reference signal RS-1 in the first indication information.

[0210] like Figure 10 As shown, the UE determines the transmission beam direction corresponding to the perception information based on the transmission beam direction of the reference signal RS-a in the first indication information and the offset angle γ. Here, RS-a is a reference signal sent by the UE, and its beam direction is known and obtained from the QCL parameters.

[0211] As an optional embodiment, the second indication information includes a location parameter of the sensing target. The location parameter of the sensing target described in this embodiment is used to indicate the transmission beam direction or the reception beam direction of the sensing information (a sensing signal or sensing data). The location parameter of the sensing target is associated with the sensing information in the configuration.

[0212] Optionally, the position parameter of the perception target is the three-dimensional coordinates (ie, X, Y, Z) of the position of the perception target.

[0213] It should be understood that the second indication information includes a first parameter (basic parameter value), which includes the X coordinate of the perceived target (e.g., 0-2000 meters), the first Y coordinate (e.g., 0-2000 meters), and the first Z coordinate (e.g., 0-100 meters). Assume that the default indication resolution is 1 meter.

[0214] The indicated orientation of the above-mentioned coordinates X, Y, and Z can use a default range or can be based on protocol agreement or configuration (such as based on scenario configuration or based on the capabilities of the sending node (indicating device), or based on the reference position of the origin coordinates). For example, for a base station as a sensing node (indicated device), if it senses a preset target in the sky, the X coordinate range is 0-2000 meters; if the sensing node is a terminal, the X coordinate range is 0-300 meters. Optionally, the resolution of the indicated value defaults to 1 meter, or is based on protocol agreement or configuration.

[0215] Optionally, the second indication information further includes one or more of the following:

[0216] the offset of the position parameter;

[0217] The third range indication of the position parameter is used to indicate that the value range of the position parameter is increased; optionally, the third range indication range of the position parameter of the perception target includes a third indication range of the X coordinate, a third indication range of the Y coordinate and / or a third indication range of the Z coordinate.

[0218] The fourth range indication of the position parameter is used to indicate that the value range of the position parameter is reduced; optionally, the fourth range indication range of the position parameter of the perception target includes a fourth indication range of the X coordinate, a fourth indication range of the Y coordinate and / or a fourth indication range of the Z coordinate.

[0219] That is, the second indication information includes not only the first parameter but also the second parameter, the third parameter and / or the fourth parameter.

[0220] The second parameter includes a third indication range of the X coordinate (ie, a larger range of values of the X coordinate), or a fourth indication range of the X coordinate (ie, a finer value of the X coordinate).

[0221] The third parameter includes a third indication range of the Y coordinate (range) (ie, a larger range of values of the Y coordinate), or a fourth indication range of the Y coordinate (refine) (ie, a finer value of the Y coordinate).

[0222] The fourth parameter includes a third indication range of the Z coordinate (range) (ie, a larger range of values of the Z coordinate) or a fourth indication range of the Z coordinate (refine) (ie, a finer value of the Z coordinate).

[0223] It should be noted that the coordinates X, Y, and Z can be individually configured with the third range indication or the fourth range indication (ie, configured as a large range value range or a fine value refine) or not configured with this parameter, which is not limited here.

[0224] Here, the second parameter further expands the indication resolution of the X coordinate, that is, increases or decreases the value range of the X coordinate.

[0225] The third parameter further expands the indication resolution of the Y coordinate, that is, increases or decreases the value range of the Y coordinate.

[0226] The fourth parameter further expands the indication resolution of the Z coordinate, that is, increases or decreases the value range of the Z coordinate.

[0227] Here, range means that the indicated resolution becomes larger, or the indicated range becomes larger; refine means that the indicated resolution becomes smaller, or the indicated range becomes smaller.

[0228] Regarding the relationship between the first parameter and the second / third / fourth parameter, take the second / third as an example, see Figure 11 Taking X and Y coordinates as an example, assuming that the first parameter X = 10 meters and Y = 10 meters represents the position of the sensed target, the unit scale is meters, and the position coordinates P(X, Y) of the sensed target can range from P(10.0 meters, 10.0 meters) to P(11.0 meters, 11.0 meters).

[0229] If the third range indication (increased range) is used, for example, the second parameter indicates X=1, Y=1, and the position coordinates P(X, Y) of the sensed target can range from P(10.0 m, 10.0 m) to P(12.0 m, 12.0 m).

[0230] If the fourth range indication (fine indication) is used: for example, the second parameter indicates X=2, Y=2 (each unit represents 0.25 meters), the position coordinates P(X, Y) of the sensed target can range from P(10.5 meters, 10.5 meters) to P(10.75 meters, 10.75 meters).

[0231] The following takes the configuration of coordinate X as an example to illustrate the method of configuring coordinates.

[0232] Coordinate X configuration parameters

[0233] {

[0234] X coordinate value (e.g. 200) / / Note: The default value is 0-2000, with an indication accuracy of 1 meter;

[0235] X coordinate offset (e.g. 100) / / Note: Optional configuration parameter, offset relative to the indication range of 0-2000, here changed to 100 to 2100 meters;

[0236] The third range of the X coordinate indicates range (such as: 2); / / Note: Optional configuration parameter, the value range is 0 to 3. 0 means 2 meters, 1 means 4 meters, 2 means 8 meters, and 3 means 16 meters; (or use the formula: 2 (range+1) rice)

[0237] The fourth range of the X coordinate indicates refine (such as: 2); / / Note: Optional configuration parameter, the value range is 0 to 3. 0 means 0.5 meters, 1 means 0.25 meters, 2 means 0.125 meters, and 3 means 0.0625 meters; (or use the formula: 2 -(range+1) );

[0238] Note: You can configure at most one of the range and refine options above.

[0239] }

[0240] Assuming the coordinate X is configured above: the value of the calculated coordinate X is: 200+100=300 meters.

[0241] When the range is configured as 2, the X value can be between 300 and 308 meters.

[0242] When the refine parameter is set to 2, the X value can be between 300 and (300 + 0.125) meters.

[0243] It should be noted that the above offset can be specified by the protocol to reduce protocol indication overhead, such as selecting one from the protocol configuration {offset-400, offset-200, offset0, offset200, offset400}.

[0244] When indicating range or refine, you can use a bit to indicate which one to use.

[0245] The specific contents of the above range and refine instructions can be realized through configuration or the default protocol values.

[0246] In this embodiment, the second indication information includes a location parameter of the sensing target. Accordingly, in step 502, determining the transmitting beam direction or the receiving beam direction corresponding to the sensing information according to the indication information includes:

[0247] According to the position parameters of the sensing target and the position parameters of the indicated device, the transmitting beam direction or the receiving beam direction corresponding to the sensing information is determined.

[0248] The scene corresponding to step 502 can be found in Figure 12 Here, the location parameters of the device being pointed to are known.

[0249] Assuming the position coordinates of the pointed device are (X0, Y0, Z0), and the position coordinates of the sensing target are P(X, Y, Z), to distinguish them, we define the azimuth angle A (φ) and the pitch angle Z (θ). The specific calculation process is as follows:

[0250] dx=X-X0; dy=Y-Y0; dz=Z-Z0

[0251]

[0252] φ=tan -1 (dy / dx)

[0253]

[0254] As another optional embodiment, the second indication information includes location parameters of the reference node, a direction angle and a propagation delay of a reference beam.

[0255] It should be understood that the second indication information is used to indicate the position coordinates of a possible perceived target. Figure 13 , gNB-1 (gNB-1 location coordinates (X1, Y1, Z1)) serves as the reference node and sends a beam with a reference beam direction angle α, and its propagation delay (echo delay) is τ.

[0256] The propagation delay τ refers to the transmission time of the speed of light (electromagnetic wave speed) from the reference node to the location of the sensing target. The propagation delay τ can be expressed in nanoseconds, microseconds, milliseconds, seconds, or OFDM symbols; or other distance parameters can be used to replace the propagation delay. The propagation delay τ can be measured by sensing nodes (such as Figure 13 It is obtained by single-base perception (gNB-1 in the figure) or calculated by sensing the position parameters of the target.

[0257] In this embodiment, optionally, the second indication information further includes one or more of the following:

[0258] The offset of the direction angle;

[0259] a first range indication of the direction angle, wherein the first range indication is used to indicate that a value range of the direction angle increases;

[0260] The second range indication of the direction angle is used to indicate that the value range of the direction angle is reduced.

[0261] Here, the directional angle refers to the directional angle of the reference beam. The specific description and explanation of the directional angle are detailed in the embodiment section related to the first indication information above. No further details will be given here.

[0262] Optionally, the second indication information further includes one or more of the following:

[0263] The offset of the position parameter;

[0265] A fourth range indication of the position parameter, wherein the fourth range indication is used to indicate that a value range of the position parameter is reduced.

[0266] Here, the location parameter is the location parameter of the reference node, and the specific description and explanation of the location parameter are detailed in the embodiment section involving the second indication information including the location parameter of the sensing target, which will not be repeated here.

[0267] Based on this, in some embodiments, in step 502, determining the transmitting beam direction or receiving beam direction corresponding to the sensing information according to the indication information includes:

[0268] a1, determining the location parameters of the sensing target according to the second indication information;

[0269] In an optional embodiment, the step a1 of determining the location parameter of the sensing target according to the second indication information includes:

[0270] a11, determining a positional relationship between the reference node and the sensing target according to the direction angle of the reference beam and the propagation delay;

[0271] See also Figure 13 , the position coordinates of the reference node are (X1, Y1, Z1), the direction angle of the reference beam is α, and the propagation delay is τ.

[0272] Specifically, the displacement r1 between the reference node and the target is calculated based on the propagation delay τ and the electromagnetic wave velocity c. The positional relationship between the reference node and the target is determined based on the displacement r1 and the reference beam's directional angle α. The positional relationship between the reference node and the target refers to the target's direction and distance relative to the reference node.

[0273] It should be noted that the direction of the perceived target relative to the reference node is expressed as the direction angle α of the perceived target relative to the reference node, and the direction angle α of the perceived target relative to the reference node includes the azimuth angle A (φ1) and the zenith angle Z (θ1); the distance of the perceived target relative to the reference node includes: based on the three-dimensional coordinates, the distance r1*sin(θ1)cos(φ1) of the perceived target relative to the reference node in the X-axis direction, the distance r1*sin(θ1)sin(φ1) of the perceived target relative to the reference node in the Y-axis direction, and the distance r1*cos(θ1) of the perceived target relative to the reference node in the Z-axis direction.

[0274] a12. Determine the position parameters of the perception target according to the position parameters of the reference node and the positional relationship between the reference node and the perception target.

[0275] Here, the position coordinates (X, Y, Z) of the perceived target can be calculated using the following formula:

[0276] X=X1+r1*sin(θ1)cos(φ1)

[0277] Y=Y1+r1*sin(θ1)sin(φ1)

[0278] Z=Z1+r1*cos(θ1)

[0279] a2. Determine a transmitting beam direction or a receiving beam direction corresponding to the sensing information according to the position parameters of the sensing target and the position parameters of the indicated device.

[0280] Here, the position parameters of the indicated device are known, see Figure 13, the indicated device is gNB-2, and the location coordinates of the indicated device gNB-2 are (X2, Y2, Z2).

[0281] Here, the transmit beam direction or receive beam direction corresponding to the sensing information can be calculated using the following formula:

[0282] dx=X-X2; dy=Y-Y2; dz=Z-Z2

[0283]

[0284] φ2=tan -1 (dy / dx)

[0285]

[0286] Here, the transmission beam direction or the reception beam direction corresponding to the sensing signal includes the azimuth angle A (φ2) and the pitch angle Z (zenith angle Z, θ2).

[0287] The beam direction determination method of the embodiment of the present application receives indication information sent by an indication device, and the indication information includes first indication information or second indication information, the first indication information is used to indicate the direction of the transmitting beam or the direction of the receiving beam, and the second indication information is used to determine the position of the perception target; finally, according to the indication information, the transmitting beam direction or the receiving beam direction corresponding to the perception information is determined; firstly, the indicated device can determine the transmitting beam direction corresponding to the perception information to be sent based on the above indication information, solve the problem of how to indicate the transmitting beam direction corresponding to the perception signal, and avoid mutual interference between adjacent perception nodes; secondly, the indicated device can determine the receiving beam direction corresponding to the perception information based on the above indication information, solve the problem of how to indicate the receiving beam direction corresponding to the perception signal, and improve the transmission efficiency of the perception signal.

[0288] like Figure 14 FIG2 is a flow chart of a beam direction determination method according to an embodiment of the present application, which is executed by an indicator device. Optionally, the indicator device is a perception server (also known as a perception signal configuration node), a base station, or a terminal. The method includes:

[0289] Step 1401: Send indication information to the indicated device, where the indication information is used to determine the transmitting beam direction or the receiving beam direction corresponding to the perception information.

[0308] A fourth range indication of the position parameter, wherein the fourth range indication is used to indicate that a value range of the position parameter is reduced.

[0309] It should be noted that the beam direction determination method on the indicating device side corresponds to the beam direction determination method on the indicated device mentioned above. The specific description and explanation of the relevant terms can be found on the indicated device side and will not be repeated here.

[0310] The beam direction determination method of an embodiment of the present application sends indication information to the indicated device, and the indication information is used to determine the sending beam direction or the receiving beam direction corresponding to the perception information. The indication information includes first indication information or second indication information. The first indication information is used to indicate the direction of the sending beam or the direction of the receiving beam, and the second indication information is used to determine the position of the perception target. In this way, the indication information indicates the sending beam direction or the receiving beam direction corresponding to the perception signal, thereby achieving the effect of assisting the indicated device to determine the sending beam direction or the receiving beam direction corresponding to the perception information.

[0311] like Figure 15 As shown, the embodiment of the present application further provides an indicated device, including: a memory 1520, a transceiver 1500, and a processor 1510: the memory 1520 is used to store program instructions; the transceiver 1500 is used to send and receive data under the control of the processor 1510; the processor 1510 performs the following operations:
