A communication method and related apparatus

[0001] The present application claims priority to the Chinese Patent Application No. 202410653834.6, filed on May 22, 2024, and entitled "A communication method and related apparatus", the content of which is incorporated herein by reference in its entirety. TECHNICAL FIELD

[0002] The present application relates to the field of communication technology, and in particular to an auxiliary calibration method of a network device and related apparatus. BACKGROUND

[0003] In the process of the evolution of the 5th generation (5G) mobile communication system, the communication and perception integrated technology is considered as one of the key technologies to expand the business capabilities of the mobile communication network. The core idea of this technology is to add perception capabilities on the mobile communication network to build the ability to detect, track and image the target. The two capabilities of communication and perception are integrated in one network.

[0004] The network device communicates with the terminal device through the antenna, and the antenna in the network device is usually realized in the form of an antenna panel. In the process of actually installing the network device, it is necessary to adjust the orientation of the antenna panel according to the business requirements, which includes various angles, such as azimuth angle, elevation angle and / or roll angle, etc.

[0005] However, in the process of actually installing the network device, the orientation of the antenna panel often has installation tolerance. In addition, due to the large area of the antenna panel, its orientation is easily affected by the environment, especially in strong wind weather, it is difficult for the antenna panel to maintain at the set orientation. Manual calibration of the network device consumes too much manpower and is difficult to perform. SUMMARY

In the technical solutions provided in the embodiments of the present application, the device for implementing the function of the network device is taken as an example to describe the technical solutions provided in the embodiments of the present application.

[0100] (3) Configuration and pre-configuration: in the present application, configuration and pre-configuration will be used simultaneously. The configuration refers to that the network device and / or the server sends some parameter configuration information or parameter values to the terminal through a message or signaling, so that the terminal determines the communication parameters or the resource in the transmission according to the values or information. The pre-configuration is similar to the configuration, which can be the parameter information or parameter values agreed by the network device and / or the server and the terminal device in advance, or the parameter information or parameter values adopted by the base station / network device or the terminal device according to the standard protocol, or the parameter information or parameter values pre-stored in the base station and / or the server or the terminal device. The present application does not limit this.

[0101] Further, the values and parameters can be changed or updated.

[0102] (4) The terms "system" and "network" in the embodiments of the present application can be used interchangeably. "Multiple" refers to two or more. "And / or" describes the association relationship of the associated objects, which means that there can be three relationships, for example, A and / or B, which can represent the cases of A alone, A and B together, and B alone, where A and B can be singular or plural. The character " / " generally represents an "or" relationship between the associated objects before and after it. "At least one of the following" or similar expressions refers to any combination of these items, including any combination of single item or multiple items. For example, "at least one of A, B and C" includes A, B, C, AB, AC, BC or ABC. In addition, unless otherwise specified, the ordinal numbers "first", "second", etc. mentioned in the embodiments of the present application are used to distinguish multiple objects, and are not used to limit the order, time sequence, priority or importance of the multiple objects.

[0103] (5) In the embodiments of the present application, "sending" and "receiving" represent the direction of signal transmission. For example, "sending information to XX" can be understood as that the destination of the information is XX, which can include direct sending through the air interface, or indirect sending through the air interface by other units or modules. "Receiving information from YY" can be understood as that the source of the information is YY, which can include direct receiving from YY through the air interface, or indirect receiving from YY through the air interface from other units or modules. "Sending" can also be understood as the "output" of the chip interface, and "receiving" can also be understood as the "input" of the chip interface.

[0104] In other words, the sending and receiving can be between devices, such as between a network device and a terminal device, or can be within a device, such as between components, modules, chips, software modules or hardware modules within a device through a bus, a wire or an interface.

[0105] It can be understood that the information can be processed, such as encoding and modulation, between the source and the destination of the information sending, but the destination can understand the effective information from the source. Similar expressions in this application can be similarly understood, and will not be repeated.

[0106] (6) In the embodiments of the present application, “indication” can include direct indication and indirect indication, and can also include explicit indication and implicit indication. The information indicated by a certain information (indication information described below) is referred to as to-be-indicated information. In the implementation process, there are many ways to indicate the to-be-indicated information, for example, but not limited to, the to-be-indicated information can be directly indicated, such as the to-be-indicated information itself or an index of the to-be-indicated information. The to-be-indicated information can also be indirectly indicated by indicating other information, where the other information and the to-be-indicated information have an association relationship. The to-be-indicated information can also be indicated only by a part, and the other part of the to-be-indicated information is known or agreed in advance. For example, the indication of a specific information can be achieved by means of the arrangement order of each information agreed in advance (for example, protocol predefined), thereby reducing the indication overhead to a certain extent. The present application does not limit the specific manner of indication. It can be understood that for the sender of the indication information, the indication information can be used to indicate the to-be-indicated information, and for the receiver of the indication information, the indication information can be used to determine the to-be-indicated information.

[0107] (7) Sensing technology.

[0108] Sensing technology refers to the use of a communication network to detect, track and image a target. The technical principle of sensing technology is different from that of communication technology. Communication technology is that the sender modulates information on radio waves and sends it to the receiver, and the receiver demodulates the signal carried on the radio waves to obtain the information. Sensing technology needs the sender to send radio waves in a specific direction. When the radio waves irradiate the surface of the target, reflected waves are formed, so that the receiver obtains the position, speed and type of the target by receiving and processing the reflected waves.

[0109] The sensing technology can be generally divided into two modes: single-station sensing and double-station sensing. In the single-station sensing, the sending end and the receiving end of the sensing signal are the same device. In the sensing signal flow, the sensing station not only sends the sensing signal, but also receives the signal reflected by the target surface (also known as echo signal). Therefore, the single-station sensing mode is also called self-sending and self-receiving mode, as shown in FIG. 1, which is a schematic diagram of a single-station sensing scene. In the double-station sensing, the sending end and the receiving end of the sensing signal are different devices. In the sensing signal flow, the sensing station A sends the sensing signal, and the signal reflected by the target surface is received by the sensing station B. Therefore, the double-station sensing mode is also called A-sending and B-receiving mode, as shown in FIG. 2, which is a schematic diagram of a double-station sensing scene.

[0110] For ease of understanding, please refer to FIG. 3, which is a schematic diagram of a sensing scene in an embodiment of the present application. In the process of communication between the network device and the terminal device in FIG. 3, the network device can also sense objects without communication capability, such as the car and the user in FIG. 3.

[0111] Further, the sensing scene shown in FIG. 3 can be further divided into various sub-scenes. For example, the sensing scene shown in FIG. 4, taking the network device as a base station and the terminal device as a user equipment (UE) as an example. FIG. 4 is another schematic diagram of a sensing scene in an embodiment of the present application. The sensing scene can include the following modes: (1) the base station sends the sensing signal by itself, and the base station receives the echo signal of the sensing signal by itself; (2) the UE sends the sensing signal by itself, and the UE receives the echo signal of the sensing signal by itself; (3) the base station A sends the sensing signal, and the base station B receives the echo signal of the sensing signal, the base station A and the base station B being different base stations; (4) the UE A sends the sensing signal, and the UE B receives the echo signal of the sensing signal, the UE A and the UE B being different UEs; (5) the base station sends the sensing signal, and the UE receives the echo signal of the sensing signal; (6) the UE sends the sensing signal, and the base station receives the echo signal of the sensing signal.

[0112] In the present application, the same or similar parts among various embodiments can be mutually referred to, unless otherwise specified. In the various embodiments in the present application, and the various methods / designs / implementation manners in the embodiments, the terms and / or descriptions in different embodiments, and the various methods / designs / implementation manners in the embodiments are consistent and can be mutually referred to, unless otherwise specified and logically conflicted. The technical features in different embodiments, and the various methods / designs / implementation manners in the embodiments can be combined to form new embodiments, methods, or implementation manners according to their inherent logical relationship. The implementation manners of the present application described below do not constitute a limitation on the protection scope of the present application.

[0113] The present application can be applied to a long term evolution (LTE) system, a new radio (NR) system, or a communication system evolved after 5G (for example, 6G, etc.). The communication system includes at least one network device and / or at least one terminal device.

[0114] FIG. 5 is a schematic diagram of an architecture of a communication system 1000 to which embodiments of the present application are applied.

[0115] As shown in FIG. 5, the communication system includes a radio access network 100 and a core network 200. Optionally, the communication system 1000 can also include an Internet 300. The radio access network 100 can include at least one radio access network device (which can also be understood as a network device as described above, such as 110a and 110b in FIG. 5), and can also include at least one terminal (which can also be understood as a terminal device as described above, such as 120a-120j in FIG. 5). In addition, the radio access network device can be a macro base station (such as 110a in FIG. 5), a micro base station or an indoor station (such as 110b in FIG. 5), a relay node or a donor node, etc. It can be understood that all or part of the functions of the radio access network device in the present application can also be implemented by software functions running on hardware, or by virtualized functions instantiated on a platform (such as a cloud platform). The embodiments of the present application do not limit the specific technology and specific device form adopted by the radio access network device.

[0116] For ease of description, a base station is taken as an example of a radio access network device, and a terminal device is taken as an example of a terminal for description. It can be understood that when the communication system includes an integrated access and backhaul (IAB) network, the base station can be an IAB node.

[0117] In the present application, the base station and the terminal can be fixed in position or movable. The base station and the terminal can be deployed on land, including indoors or outdoors, handheld or vehicle-mounted, and can also be deployed on water, or on aircraft, balloons, and artificial satellites in the air. The embodiments of the present application do not limit the application scenarios of the base station and the terminal.

[0118] The roles of the base station and the terminal can be relative. For example, the helicopter or the drone 120i in FIG. 5 can be configured as a mobile base station, and for the terminal 120j that accesses the wireless access network 100 through the 120i, the terminal 120i is a base station. But for the base station 110a, the 120i is a terminal, that is, the 110a and the 120i communicate through a wireless air interface protocol. Of course, the 110a and the 120i can also communicate through a base station-to-base station interface protocol, and in this case, the 120i is also a base station relative to the 110a. Therefore, the base station and the terminal can be collectively referred to as a communication device, and the 110a and the 110b in FIG. 5 can be referred to as a communication device with a base station function, and the 120a-120j in FIG. 5 can be referred to as a communication device with a terminal function.

[0119] The base station and the terminal, the base station and the base station, and the terminal and the terminal can communicate through a licensed spectrum, or through an unlicensed spectrum, or through both the licensed spectrum and the unlicensed spectrum. The communication can be through a spectrum below 6 gigahertz (GHz), or through a spectrum above 6 GHz, or through both the spectrum below 6 GHz and the spectrum above 6 GHz. The embodiments of the present application do not limit the spectrum resources used for wireless communication.

[0120] In the embodiments of the present application, the functions of the base station can also be performed by a module (such as a chip) in the base station, or by a control subsystem containing base station functions. The control subsystem containing base station functions herein can be a control center in the application scenarios of the above terminals such as smart grids, industrial control, intelligent transportation, and smart cities. The functions of the terminal can also be performed by a module (such as a chip or a modem) in the terminal, or by a device containing terminal functions.

[0121] In the present application, the base station sends a downlink signal (or downlink information) to the terminal, and the downlink signal (or downlink information) is carried on a downlink channel. The terminal sends an uplink signal (or uplink information) to the base station, and the uplink signal (or uplink information) is carried on an uplink channel.

[0122] It should be understood that the present application can be applied to a long term evolution (LTE) system, a new radio (NR) system, or a communication system evolved after 5G (such as 6G, etc.). The communication system includes a network device and a terminal device.

[0123] The network device communicates with the terminal device through an antenna, and the antenna in the network device is usually implemented in the form of an antenna panel. In the actual installation process of the network device, the orientation of the antenna panel needs to be adjusted according to the business requirements, and the orientation of the antenna panel includes various angles, such as azimuth angle, pitch angle and / or roll angle, etc. However, in the actual installation process of the network device, the orientation of the antenna panel often has installation tolerance. In addition, due to the large area of the antenna panel, its orientation is easily affected by the environment, especially in windy weather, it is difficult for the antenna panel to maintain at the set orientation. When the orientation of the antenna panel of the network device has an error from the predetermined angle, using the network device for sensing will introduce a large sensing error, causing the decline of sensing performance. For example, the scenario shown in FIG. 6 is a sensing error diagram in an embodiment of the present application. When the angle deviation of the antenna panel of the network device is 0.5 degrees, about 8.7 meters of positioning error is caused for the target with a sensing distance of 1000 meters from the network device. That is, the theoretical position of the terminal device obtained by the network device in FIG. 6 is about 8.7 meters different from the actual position of the terminal device. The manual calibration of the network device consumes too much manpower and is difficult to perform.

[0124] Based on this, an embodiment of the present application proposes a communication method and related apparatus. First, the second communication apparatus receives the first information reported by one or more first communication apparatuses, and the first information indicates the positioning measurement accuracy supported by the first communication apparatus. Finally, the second communication apparatus receives the second information sent by the target first communication apparatus, and the second information is used to calibrate the second communication apparatus, and the target first communication apparatus is the first communication apparatus determined by the second communication apparatus from one or more first communication apparatuses according to the first information reported by one or more first communication apparatuses. Through the above method, the second communication apparatus calibrates the second communication apparatus according to the second information fed back by the target first communication apparatus, which can effectively improve the sensing performance of the second communication apparatus and reduce the overhead of the position calibration and / or angle calibration of the second communication apparatus.

[0125] Next, the embodiments of the present application are introduced in combination with the drawings. There are various possible implementation manners for the first communication apparatus and the second communication apparatus in the embodiments of the present application, as follows:

[0126] In one possible implementation manner, the first communication apparatus in the embodiments of the present application can be a terminal device, and the second communication apparatus can be a network device and / or a core network device.

[0127] In another possible implementation manner, the first communication apparatus in the embodiments of the present application can be a network device, and the second communication apparatus can be another network device and / or a core network device.

[0128] In another possible implementation, the first communication apparatus in the embodiment of the present application can be a terminal device, and the second communication apparatus can be another terminal device.

[0129] First, refer to Fig. 7, which is a flow diagram of one embodiment of a communication method in the embodiment of the present application. The embodiment of the present application proposes a communication method, which includes the following steps:

[0130] S1, the first communication apparatus sends first information to the second communication apparatus.

[0131] In step S1, the first communication apparatus can send (or report) first information to the second communication apparatus, where the first information indicates the positioning measurement accuracy supported by the first communication apparatus.

[0132] In one possible implementation, the first information indicates a positioning measurement accuracy value supported by the first communication apparatus, or the first information indicates a positioning measurement accuracy range value supported by the first communication apparatus.

[0133] Exemplarily, when the first information indicates the positioning measurement accuracy value supported by the first communication apparatus, one example of the first information is shown in Table 2.

[0134] Table 2

[0135] Specifically, when the value of the first information reported by the first communication apparatus is "00", it indicates that the positioning measurement accuracy of the first communication apparatus is 0.01 meters. When the value of the first information reported by the first communication apparatus is "01", it indicates that the positioning measurement accuracy of the first communication apparatus is 0.1 meters. When the value of the first information reported by the first communication apparatus is "10", it indicates that the positioning measurement accuracy of the first communication apparatus is 0.2 meters. When the value of the first information reported by the first communication apparatus is "11", it indicates that the positioning measurement accuracy of the first communication apparatus is 0.3 meters.

[0136] In another possible implementation, when the first information indicates the positioning measurement accuracy range value supported by the first communication apparatus, one example of the first information is shown in Table 3.

[0137] Table 3

[0138] Specifically, when the value of the first information reported by the first communication device is "00", it indicates that the positioning measurement accuracy of the first communication device is less than 0.01 meters. When the value of the first information reported by the first communication device is "01", it indicates that the positioning measurement accuracy of the first communication device is 0.01 meters to 0.1 meters. When the value of the first information reported by the first communication device is "10", it indicates that the positioning measurement accuracy of the first communication device is 0.1 meters to 0.2 meters. When the value of the first information reported by the first communication device is "11", it indicates that the positioning measurement accuracy of the first communication device is greater than 0.2 meters.

[0139] S2, the second communication device determines the target first communication device according to the first information.

[0140] In step S2, after the second communication device receives the first information reported by one or more first communication devices, the second communication device determines the target first communication device from the one or more first communication devices according to the first information reported by the one or more first communication devices. Then, the second communication device calibrates using the second information of the target first communication device.

[0141] In one possible implementation, the second communication device selects the first communication device with the highest positioning measurement accuracy as the target first communication device according to the first information of the one or more first communication devices.

[0142] Optionally, the target first communication device is the first communication device on the line of sight (LOS) path of the second communication device. The LOS path refers to a path in wireless communication in which the signal is transmitted directly from the transmitting end to the receiving end without any obstacles between the transmitting end and the receiving end. The second communication device can determine whether the first communication device is on the LOS path according to the strength of the transmitting signal or the receiving signal of the first communication device.

[0143] For example, the second communication device selects the first communication device with the highest positioning measurement accuracy as the target first communication device according to the first information of the one or more first communication devices on the LOS path.

[0144] S3, the second communication device sends first indication information or a sensing signal to the first communication device.

[0145] In step S3, after the second communication device determines the target first communication device, the second communication device sends first indication information or a sensing signal to the target first communication device. The first indication information is used to indicate the position information of the first communication device reported by the first communication device. The sensing signal is used to measure the position information of the second communication device.

[0146] It should be noted that the sensing signal in the embodiments of the present application can also be referred to as a sensing frame.

[0147] In a possible implementation, when the second communication device calibrates the position information of the first communication device, the position information reported by the first communication device and the position information of the first communication device sensed by the second communication device need to correspond to each other. Therefore, the second communication device needs to indicate the time at which the first communication device reports the position information of the first communication device. In the embodiments of the present application, in order to facilitate description, the position information of the first communication device reported by the first communication device is referred to as first position information, and the first communication device can obtain the first position information in various manners, which is not limited in the embodiments of the present application.

[0148] Optionally, the first indication information includes: a reporting interval indication, the reporting interval indication being used to indicate a time interval at which the first communication device reports the first position information. For example, the reporting interval indication is specifically used to indicate a relationship between the time interval at which the first communication device reports the first position information and a sending period of the sensing signal.

[0149] For example, the reporting interval indication is as shown in Table 4.

[0150] Table 4

[0151] As shown in Table 3, taking the length of the reporting interval indication (i.e., the first indication information field) as 2 bits for example. When the value of the reporting interval indication is “00”, the period at which the first communication device reports the first position information is the same as the period at which the first communication device receives the sensing signal. For example, the first communication device sends the first position information to the second communication device once every time the first communication device receives the sensing signal. When the value of the reporting interval indication is “01”, the period at which the first communication device reports the first position information is twice the period at which the first communication device receives the sensing signal. For example, the first communication device sends the first position information to the second communication device once every time the first communication device receives the sensing signal twice. When the value of the reporting interval indication is “10”, the period at which the first communication device reports the first position information is three times the period at which the first communication device receives the sensing signal. For example, the first communication device sends the first position information to the second communication device once every time the first communication device receives the sensing signal three times. When the value of the reporting interval indication is “11”, the period at which the first communication device reports the first position information is four times the period at which the first communication device receives the sensing signal. For example, the first communication device sends the first position information to the second communication device once every time the first communication device receives the sensing signal four times.

[0152] It should be noted that the length of the sensing signal can also be referred to as a sensing frame length or a coherent processing time of sensing, which is not limited in the embodiments of the present application.

[0153] Optionally, the first indication information comprises a reporting time period indication, the reporting time period indication being used to indicate a time period in which the first communication device reports the first location information.

[0154] For example, the reporting interval indication is shown in Table 5.

[0155] Table 5

[0156] As shown in Table 4, taking the length of the reporting time period indication (i.e. the first indication information field) as an example, when the value of the reporting time period indication is "00", the first communication device reports the first location information within 1 second. When the value of the reporting time period indication is "01", the first communication device reports the first location information within 2 seconds. When the value of the reporting time period indication is "10", the first communication device reports the first location information within 3 seconds. When the value of the reporting time period indication is "11", the first communication device reports the first location information within 4 seconds.

[0157] Optionally, the first indication information can comprise the reporting interval indication and the reporting time period indication. Taking the length of the first indication information as an example, when the length of the reporting interval indication is 2 bits and the length of the reporting time period indication is 2 bits, for example, the first indication information is "0000", the meaning of the first indication information is that the first communication device feeds back the first location information to the second communication device once every time the first communication device receives the sensing signal within 1 second.

[0158] Optionally, the reporting interval indication is also used to indicate whether the first communication device reports the first location information according to the sending period of the sensing signal. Specifically, according to the agreement or pre-configuration information between the second communication device and the first communication device, it is determined that the period in which the first communication device reports the first location information is according to the period of the sensing signal. That is, the first communication device defaults to report the first location information to the second communication device once every time the first communication device receives the sensing signal. The second communication device indicates whether the first communication device reports the first location information through the value of the sensing signal (the first indication information). For example, when the value of the sensing signal (the first indication information) is 0, the first communication device does not report the first location information; when the value of the sensing signal (the first indication information) is 1, the first communication device reports the first location information to the second communication device once every time the first communication device receives the sensing signal.

[0159] S4, the first communication device sends second information to the second communication device.

[0160] In step S4, after the first communication device receives the first indication information or the sensing signal sent by the second communication device, the first communication device sends second information to the second communication device in response to the first indication information or the sensing signal.

[0161] In a possible implementation, the second information includes first position information. The first position information is position information of the first communication device obtained by the first communication device.

[0162] In another possible implementation, after the first communication device receives the sensing signal of the second communication device, the first communication device can further receive a backwave signal of the sensing signal. Then, the first communication device performs sensing processing according to the backwave signal of the sensing signal to determine position information of the second communication device. The position information of the second communication device measured by the first communication device according to the sensing signal is referred to as third position information. The second information includes the third position information.

[0163] It should be noted that the position information (including the position information of the second communication device and the position information of the first communication device) in the embodiments of the present application includes position information in the same coordinate system (for example, position information of X-axis, Y-axis and Z-axis), or latitude and longitude coordinate information, and can also include angle information. The angle information includes but is not limited to azimuth angle, pitch angle and / or roll angle, etc.

[0164] In another possible implementation, after the first communication device determines the third position information, the first communication device can further obtain theoretical position information of the second communication device. For ease of description, the theoretical position information of the second communication device is referred to as fourth position information. The first communication device can obtain the fourth position information in various ways, for example, the first communication device obtains the position information of the second communication device from a core network, which can be a positioning server (or other server) providing position information, and the position information of the second communication device is taken as the fourth position information. Alternatively, the position information of the second communication device in the embodiments of the present application can further include angle information of a panel in the second communication device.

[0165] After the first communication device obtains the third position information and the fourth position information, the first communication device can calculate an error of the third position information and the fourth position information, which is referred to as first error information in the embodiments of the present application. Specifically, the first error information includes a position error of the third position information and the fourth position information, and / or an angle error of the third position information and the fourth position information, wherein the angle error includes an azimuth angle error, a pitch angle error, and / or a roll angle error.

[0166] It should be noted that the third position information and the fourth position information need to be in the same coordinate system when the first communication device calculates the first error information.

[0167] Optionally, the first error information can further comprise an error level (or referred to as an error level field), wherein the error level indicates the precision of the first error information.

[0168] Exemplarily, the error level is shown in Table 6.

[0169] Table 6

[0170] As shown in Table 6, taking the length of the error level field as 2 bits for example. When the value of the error level is “00”, it means that the precision of the first error information is 1 digit before the decimal point, for example, the error level of the first error information is meter level. When the value of the error level is “01”, it means that the precision of the first error information is 1 digit after the decimal point, for example, the error level of the first error information is centimeter level. When the value of the error level is “10”, it means that the precision of the first error information is 2 digits after the decimal point, for example, the error level of the first error information is millimeter level. When the value of the error level is “11”, it means that the precision of the first error information is 3 digits after the decimal point, for example, the error level of the first error information is micrometer level.

[0171] Exemplarily, the first error information can be represented by the error value indication field and the error level field together, and the error value indication field is shown in Table 7.

[0172] Table 7

[0173] For example, taking the error information of the X-axis for example, when the error level field indicates 01 and the error value indication field is 110, it means that the error of the X-axis is -3*0.1=-0.3 meters.

[0174] It should be noted that the position error and the angle error can be represented by multiple error value indication fields and corresponding multiple error level fields in the first second information. For example, the first second information comprises six groups of fields, each group of fields comprises an error value indication field and a corresponding error level field, and each group of fields represents an error value in the first second information, for example: X-axis error, Y-axis error, Z-axis error, azimuth angle error, pitch angle error and roll angle error.

[0175] S5, the second communication device calibrates the second communication device according to the second information.

[0176] In step S5, after the first communication device determines the second information, the first communication device sends the second information to the second communication device. The second communication device calibrates the second communication device according to the second information.

[0177] In a possible implementation, when the second information comprises the first position information, the second communication apparatus can further determine the position information of the first communication apparatus according to the second information. Specifically, the second communication apparatus regards the second information as a reflection signal of the sensing signal after sending the sensing signal to the first communication apparatus. The second communication apparatus performs sensing processing according to the second information, and determines the position information of the first communication apparatus. In the embodiment of the application, the position information of the first communication apparatus measured by the second communication apparatus according to the second information is referred to as second position information. Then, the second communication apparatus can further obtain the theoretical position information of the first communication apparatus, which is the first position information. The second communication apparatus can obtain the first position information in various manners, for example, the second communication apparatus obtains the position information of the first communication apparatus (i.e., the first position information) from a core network, which can be a positioning server (or other server) providing the position information.

[0178] When the second communication apparatus obtains the first position information and the second position information, the second communication apparatus can calculate the error of the first position information and the second position information, which is referred to as second error information in the embodiment of the application. Specifically, the second error information comprises the position error of the first position information and the second position information, and / or the angle error of the first position information and the second position information, wherein the angle error comprises the azimuth angle error, the pitch angle error, and / or the roll angle error.

[0179] Then, the second communication apparatus calibrates the second communication apparatus according to the second error information.

[0180] In another possible implementation, when the second information comprises the first error information, the second communication apparatus calibrates the second communication apparatus according to the first error information.

[0181] In another possible implementation, when the second information comprises the third position information, the second communication apparatus can further obtain the theoretical position information of the second communication apparatus (i.e., fourth position information). The second communication apparatus can obtain the fourth position information in various manners, for example, the second communication apparatus obtains the fourth position information from a core network, which can be a positioning server (or other server) providing the position information. Then, the second communication apparatus calculates the first error information according to the third position information and the fourth position information. The second communication apparatus calibrates the second communication apparatus according to the first error information.

[0182] In the embodiment of the application, the second communication apparatus calibrates the second communication apparatus according to the second information of the target first communication apparatus to the sensing signal, which can effectively improve the sensing performance of the second communication apparatus and reduce the overhead of position calibration and / or angle calibration of the second communication apparatus.
