[0017] In the following, in conjunction with the accompanying drawings, a method for generating channel data provided by an embodiment of the present application is described in detail through specific embodiments and application scenarios.
[0018] Figure 1 A schematic flow chart of a method for generating channel data provided by an embodiment of the present invention is shown, the method comprising the following steps: S102: Using an existing network channel collection device, a multipath parameter list between a base station and the existing network channel collection device is obtained.
[0019] Among them, the multipath parameter list is used to characterize the existing network channel environment for base station and terminal antenna transmission signals.
[0020] The existing network channel acquisition device is specifically used to acquire the channel environment using the downlink air interface signal in the existing network, and may include terminal antennas. However, the actual number of antennas of the existing network channel acquisition device is greater than the number of terminal antennas of the terminal.
[0021] Commonly used downlink air interface signals include: Synchronization Signal Block (SSB) and Channel State Information Reference Signal (CSI-RS).
[0022] The multipath parameter list contains global information such as delay domain, spatial domain and polarization domain, which can characterize the entire existing network channel environment.
[0023] As an example, if the number of reference signal (Channel State Information ReferenceSignal, CSI-RS) ports configured by the base station is K, and there are L multipaths in the environment, then the multipath parameters collected on the kth port are It can be expressed as ,in For the information of the lth multipath parameter on the kth port, , through the decoding algorithm and multipath parameter extraction algorithm in the downlink air interface signal, the multipath parameter information is extracted and analyzed to obtain the lth multipath information on the kth port after analysis, including: delay , horizontal azimuth , horizontal pitch angle , vertical polarization complex gain , horizontal polarization complex gain , which can be expressed as , where T is the label of the matrix transpose.
[0024] Since the base station corresponds to multiple ports, each port has multiple multipath parameter information, so a multipath parameter list can be formed, and each path corresponding to each port has a multipath parameter.
[0025] S104: Determine a first position vector and a first angle vector of the terminal antenna based on the multipath parameter list.
[0026] The first angle vector is used to represent the angle change information of the terminal antenna.
[0027] The first position vector is used to represent the position information of the terminal antenna in the three-dimensional space.
[0028] The first angle vector is used to describe the posture change of the terminal antenna, and includes determining the first angle vector according to the angle information in the multipath parameter list collected in the real network in S102.
[0029] S106: Determine a first complex radiation pattern of the terminal antenna according to the first position vector and the first angle vector of the terminal antenna.
[0030] The first complex directivity pattern is used to characterize the radiation intensity of the terminal antenna.
[0031] Generally, when generating channel data based on the measured terminal antenna pattern, only the measurement of amplitude information is supported, such as active measurement in a darkroom to obtain a three-dimensional amplitude pattern. In addition to the measurement of amplitude information, the first complex pattern also includes position information and angle information determined based on the placement of the terminal antenna. Specifically, the first complex pattern of the terminal antenna is determined based on the first position vector and the first angle vector of the terminal antenna.
[0032] Using the above example, if there are U terminal antennas in total, the three-dimensional amplitude pattern of the u-th terminal antenna in vertical polarization and horizontal polarization can be expressed as .
[0033] Wherein, u represents the u-th terminal antenna; represents vertical polarization; v represents horizontal polarization; meas represents measurement; Indicates the horizontal azimuth of the incoming wave; represents the horizontal pitch angle of the incoming wave, and F represents the direction pattern.
[0034] Based on the three-dimensional amplitude pattern, it is assumed that for the u-th terminal antenna, its three-dimensional position vector is , the information in three-dimensional space can be expressed as: Formula 1 in, The three-dimensional position vector representing the u-th terminal antenna is taken as the first position vector of the u-th terminal antenna; They represent the coordinates of the u-th terminal antenna in the three-dimensional space. The brackets [ ] are matrices.
[0035] According to the multipath parameter list, the horizontal azimuth is obtained as , the horizontal pitch angle is The incoming wave is used as the first angle vector of the terminal antenna, and its unit angle vector is also the first angle vector r, which can be expressed as: r Formula 2 in, Indicates the cosine value of the horizontal azimuth; Indicates the sine value of the horizontal pitch angle; represents the sine of the horizontal azimuth, represents the cosine value of the horizontal pitch angle, and T is the symbol of the matrix transpose.
[0036] According to the three-dimensional position vector of the terminal antenna, i.e., the first position vector, and the angle information of the wave received by the terminal antenna, i.e., the horizontal azimuth angle and the horizontal elevation angle, the complex directional pattern of the u-th terminal antenna on the vertical polarization and the horizontal polarization is determined, and the vertical complex directional pattern on the vertical polarization and the horizontal complex directional pattern on the horizontal polarization are used as the first complex directional pattern. The formula of the first complex directional pattern is: Formula 3 ) Formula 4 in, Represents the three-dimensional amplitude pattern on vertical polarization; ) represents the three-dimensional amplitude pattern on horizontal polarization; represents the vertical complex pattern on vertical polarization; represents the horizontal complex directivity pattern on horizontal polarization; e represents the complex gain; represents the wavelength of electromagnetic wave propagation; r represents the first angle vector, represents the first position vector of the u-th terminal antenna; j represents the imaginary part; It can be seen that the first complex radiation pattern of the terminal antenna can be determined according to the first position vector and the first angle vector.
[0037] S108, generating first channel data sent by the base station to the terminal antenna according to the multipath parameter list and the first complex directional diagram, the first channel data including a first matrix of first channel response data corresponding to multiple ports of the base station.
[0038] A channel refers to a signal path provided by a wired or wireless line for transmitting signals. The first channel data is the data in the process of transmitting signals through the channel.
[0039] The first channel response data refers to the signal propagating through different paths in the channel. The lengths and propagation times of the paths are different, which causes delays and phase shifts when the signal reaches the receiver. The first channel response data includes: the energy distribution of the signal at different time points after passing through the channel. The channel response data belongs to the first channel data. The first channel data may also include data in a multipath parameter list.
[0040] Since the base station has multiple ports, the multipath parameters corresponding to each port can generate first channel response data, generate a first matrix of the first channel response data, and the generated first matrix can be used as the first channel data.
[0041] Using the above example, the first channel response data in the frequency domain from the kth port to the uth terminal antenna at the qth frequency point generated by the multipath parameters in the existing network wireless channel can be expressed as Formula 5: Formula 5:
[0042] The frequency domain is a coordinate system used to describe the characteristics of a signal in terms of frequency.
[0043] Frequency refers to a specific frequency used to transmit and receive signals in radio communications, and refers to a specific absolute frequency value. The frequency domain includes multiple frequency points. In the existing wireless channel, the first channel response data can be generated in the frequency domain of a specific frequency point based on the multipath parameters.
[0044] Among them, in formula 5 represents the first channel response data corresponding to the K-th port and the u-th terminal antenna; u represents the u-th terminal antenna; represents the kth port of the base station; p and Represents the vertical polarization and horizontal polarization data traversing all ports; indicates vertical polarization; Indicates horizontal polarization; represents L paths; represents the L path among the L paths; Indicates the horizontal azimuth of the incoming wave; Indicates the horizontal pitch angle of the incoming wave; represents complex gain; represents the imaginary part; represents the time delay; q represents the qth frequency point; f represents the frequency; F represents the directional pattern obtained according to the first complex directional pattern, that is, Represents a first complex directional pattern corresponding to a vertical complex directional pattern of vertical polarization and a horizontal complex directional pattern of horizontal polarization of the u-th terminal antenna.
[0045] According to the multipath parameters in the multipath parameter list and the first complex directional diagram, the first channel response data is generated after calculation. Since there are multiple ports and multipath parameters, multiple first channel response data can be generated to form a first matrix. The first matrix of the first channel response data corresponding to the multiple ports can be used as the first channel data.
[0046] The technical solution of the embodiment of the present application is adopted, and the multipath parameter list between the base station and the existing network channel acquisition device is used to obtain the existing network channel acquisition device. Among them, the multipath parameter list is used to characterize the existing network channel environment of the base station and the terminal antenna transmission signal; based on the multipath parameter list, the first position vector and the first angle vector of the terminal antenna are determined, and the first angle vector includes the angle change information of the terminal antenna; according to the first position vector and the first angle vector of the terminal antenna, the first complex directional diagram of the terminal antenna is determined, and the first complex directional diagram is used to characterize the radiation intensity of the terminal antenna; according to the multipath parameter list and the first complex directional diagram, the first channel data sent by the base station to the terminal antenna is generated, and the first channel data includes the first matrix of the first channel response data corresponding to the multi-port of the base station. Among them, by obtaining a multipath parameter list of base station and terminal antenna transmission signals in an existing network channel environment, determining a first position vector and a first angle vector of the terminal antenna, and then determining a first complex directional pattern of the terminal antenna, the first complex directional pattern including the position and the angle can be determined, and based on the first complex directional pattern and the multipath parameter list, a first matrix of first channel response data sent by the base station's multi-port to the terminal antenna is calculated and used as the first channel data, so that channel data in the existing network channel environment can be obtained in real time, without generating channel data based on simulation or actual measurement, directly obtaining a multipath parameter list in the existing network environment and generating channel data based on the first complex directional pattern, which can solve the problem of difficulty in obtaining corresponding channel data in the existing network environment.
[0047] In one embodiment, when the terminal antenna has a rotation angle, the method may further perform the following steps A1-A3: Step A1, based on the multipath parameter list, obtain the rotation angle of the terminal antenna in three-dimensional space and generate a rotation vector matrix.
[0048] The terminal antenna has a rotation angle, including: in order to expand the amount of the above-mentioned first channel data generated, broadband channel data can be generated for terminals in any posture, such as 5G terminals. When the terminal has any posture, the terminal antenna changes relative to the first position vector and the first angle vector in the three-dimensional space, that is, it has a rotation angle.
[0049] As an example, using the content in the above example, the rotation angles of the terminal antenna in three-dimensional space are , which represents the angle of rotation relative to the fixed terminal antenna in the coordinate system. The terminal is rotated in the original three-dimensional space, and the terminal antenna has a rotation angle, which generates a rotation vector matrix , the rotation vector matrix is calculated as follows:
[0050] in, represents the rotation vector matrix; They are the rotation angles in three-dimensional space respectively; sin is the sine value corresponding to each angle, and cos is the cosine value corresponding to each angle.
[0051] Step A2: Generate a second position vector and a second angle vector having a rotation vector matrix according to the rotation vector matrix.
[0052] Using the above example, according to the above rotation vector matrix R, according to the above first position vector without the rotation vector matrix , the u-th terminal antenna has a three-dimensional position vector with a rotation vector moment, that is, the second position vector The calculation formula is: Formula 6 According to the above multipath parameter list, the horizontal azimuth angle is obtained as follows: , the horizontal pitch angle is , after the terminal antenna undergoes three-dimensional rotation, the second angle vector obtained according to the angle in the local coordinate system can be expressed as: =acos Formula 7 Formula 8 Among them, a new horizontal azimuth is formed , and the new horizontal pitch angle .Will and as the second angle vector.
[0053] Step A3: Generate a second complex directional pattern based on the second position vector and the second angle vector.
[0054] Using the second position vector from the above example and the second angle vector and , the calculation formula for obtaining the second complex directional pattern includes: Formula 9 Formula 10 Among them, it can be compared with the first complex directional diagram, Represents the second complex directional pattern of the u-th terminal antenna, including the vertical complex directional pattern and the horizontal complex directional pattern on the vertical and horizontal polarizations; Includes vertical polarization and horizontal polarization that can traverse all ports; Represents the vertical complex pattern on vertical polarization when the terminal antenna has a rotation angle, Represents the horizontal complex pattern on horizontal polarization when the terminal antenna has a rotation angle; represents a second position vector of the u-th terminal antenna; represents the new horizontal azimuth, represents the new horizontal pitch angle; the remaining letters are the same as those in the above formula 3 and formula 4 and are not repeated here.
[0055] In this embodiment, when the terminal changes in any posture, the terminal antenna has a rotation angle. Then, there is a rotation angle in three-dimensional space, and a rotation angle matrix is generated. According to the calculation formula, a second position vector and a second angle vector are generated, and then the second complex radiation pattern is determined. Compared with the terminal antenna when it is not rotated, there is no need to re-collect data, and only the rotation angle needs to be determined to determine the corresponding second complex radiation pattern, which can improve the efficiency of obtaining the channel data of the terminal antenna.
[0056] In one embodiment, after generating the second complex directional pattern based on the second position vector and the second angle vector (ie, step A3), the following steps B1-B2 may be performed: Step B1, determining second channel response data from the multi-port of the base station to the terminal antenna at a target frequency point according to the multipath parameter list and the second complex directional diagram.
[0057] The target frequency point includes a target frequency value in the frequency domain of the transmission broadband.
[0058] Broadband transmission is a method of digital signal transmission, which converts the digital signal into an audio signal of a specific bandwidth for transmission, and then converts it back at the receiving end.
[0059] Frequency domain is a coordinate system used to describe the characteristics of a signal in terms of frequency.
[0060] The target frequency point has multiple frequency points in the frequency domain. In radio communications, the specific frequency used to transmit and receive signals refers to the specific absolute frequency value.
[0061] The rotation angle of the terminal antenna is determined according to the multipath parameter list, and the second channel response data can be calculated according to the second complex directional pattern obtained in step A3.
[0062] According to the multipath parameter list, the three-dimensional rotation angle corresponding to the terminal antenna is obtained, and the above formula and example are used to obtain the second complex directional diagram. The three-dimensional rotation angle can be The generated frequency domain second channel response data from the kth port to the uth terminal antenna at the qth frequency point is expanded by the posture of the terminal antenna, and is expressed as follows: Formula 11:
[0063] Formula 12:
[0064] Formula 11 represents the response data but is not specific to the frequency point, and Formula 12 represents the frequency domain second channel response data at the qth frequency point.
[0065] in, Indicates Channel response data of the u-th terminal antenna on the port; Represents the second complex directivity pattern after traversing vertical polarization and horizontal polarization; represents the new horizontal azimuth on the lth path; represents the new horizontal pitch angle on the lth path; represents the frequency domain second channel response data from the kth port to the uth terminal antenna at the qth frequency point; represents the new horizontal azimuth angle on the lth path of the kth port; represents the new horizontal pitch angle on the lth path of the kth port; the remaining letters have the same meaning as those expressed in the above formula 5 and will not be described here.
[0066] Step B2: Use the second channel response data as the second channel data of the terminal antenna, wherein the second channel data includes a second matrix of second channel response data corresponding to multiple ports of the base station.
[0067] Since the second channel response data is a matrix, the second channel data is the channel data when the terminal antenna is in any posture.
[0068] It should be noted that, in addition to the self-space, any posture can also include hand-held scenarios and call scenarios. For example, if the terminal has U terminal antennas, the three-dimensional amplitude pattern of the u-th antenna in vertical polarization and horizontal polarization in the hand-held scenario can be expressed as and , where handshake h Indicates the handshake scenario, and the remaining letters are the same as above and are not repeated. Substitute the two three-dimensional amplitude directional patterns into Formula 5 to obtain the frequency domain channel response data of the u-th antenna at the q-th frequency point in the handheld scenario. Then refer to Formula 5-Formula 8 to obtain the frequency domain channel response data in the handheld scenario; similarly, the frequency domain channel response data in the call scenario can also be obtained.
[0069] In this embodiment, the second channel response data is calculated based on the multipath parameter list and the second complex directional diagram, and the second channel response data is determined as the second channel data. When the terminal antenna has a rotation angle, the second channel data in the existing network is quickly acquired, and the angular rotation in dimensions such as azimuth, pitch angle, and polarization is combined, and extended calculations can be performed on the channel data set for any posture and any scene.
[0070] In one embodiment, according to the first position vector and the first angle vector of the terminal antenna, the first complex pattern of the terminal antenna is determined (ie, S106), and the following steps C1-C2 may be performed: Step C1, determining a vertical complex directional pattern of the terminal antenna on vertical polarization and a horizontal complex directional pattern on horizontal polarization according to a first position vector and a first angle vector of the terminal antenna, wherein both the vertical complex directional pattern and the horizontal complex directional pattern include: a first position vector and a first angle vector.
[0071] Vertical polarization refers to when the direction of the electric field is perpendicular to the ground.
[0072] The vertical complex directional pattern is the directional pattern of the terminal antenna on the vertical polarization. As shown in the calculation process of the above formula 3. It can be seen from formula 3 that according to the first position vector of the terminal antenna and the first angle vector and , calculate the vertical complex radiation pattern of the terminal antenna on vertical polarization.
[0073] Horizontal polarization refers to when the direction of the electric field is parallel to the ground.
[0074] The horizontal complex pattern is the pattern of the terminal antenna on horizontal polarization. As shown in the calculation process in the above formula 4. It can be seen from formula 4 that according to the first position vector of the terminal antenna and the first angle vector and , calculate the horizontal complex radiation pattern of the terminal antenna on horizontal polarization.
[0075] Step C2: generating a first complex directional pattern of the terminal antenna based on the vertical complex directional pattern and the horizontal complex directional pattern.
[0076] The vertical complex directional pattern and the horizontal complex directional pattern are determined as the first complex directional pattern of the terminal antenna.
[0077] In this embodiment, the vertical complex radiation pattern and the horizontal complex radiation pattern are determined according to the calculation formula corresponding to the first position vector and the first angle vector, the phase information of the terminal antenna is obtained according to the vertical complex radiation pattern and the horizontal complex radiation pattern, and the vertical complex radiation pattern and the horizontal complex radiation pattern are determined as the first complex radiation pattern.
[0078] In one embodiment, according to the multipath parameter list and the first complex directional diagram, the first channel data sent by the base station to the terminal antenna is generated (ie, S108), and the following steps D1-D2 may be performed: Step D1, acquiring first channel response data from a multi-port of a base station to a terminal antenna at a target frequency point according to a multipath parameter list and a first complex directivity diagram.
[0079] In the existing network communication environment, the channel environment perceived by the terminal is the combined effect of the base station radiation beam and the propagation channel environment. According to the 3GPP 38.211-38.214 series of protocols, the reference channel perceived by the terminal is the multiple-input multiple-output (MIMO) channel matrix from the logical port to each terminal antenna of the terminal.
[0080] As an example, using the content in the above example, there are Q frequency points in the transmission broadband, and the frequency of the qth frequency point can be expressed as Then in the existing network environment, the channel response from the kth port to the uth antenna at the qth frequency point can be expressed as the following formula 13: Formula 13:
[0081] Where Field represents the communication across the field; u represents the u-th terminal antenna; k represents the k-th port; L represents a total of L paths; l represents the l-th path among the L paths; S represents the number of base station antennas; s represents the s-th base station antenna; Indicates the bandwidth of the port corresponding to the s-th base station; VV indicates vertical polarization, VH indicates vertical-horizontal polarization, HV indicates horizontal-vertical polarization, and HH indicates horizontal polarization, which respectively indicate the vibration of the signal in the horizontal and vertical directions; AoD refers to the departure angle when the signal leaves the base station antenna, i.e. the azimuth, which is used to determine the direction of signal transmission; ZoD indicates the elevation angle when the signal leaves the base station; is the polarization factor, which is the polarization factor from the kth logical port to the sth terminal antenna; and It is represented by the vertical complex directional pattern and horizontal directional pattern of the s-th base station antenna in vertical polarization and horizontal polarization; and It is expressed as the vertical complex radiation pattern and horizontal complex radiation pattern of the u-th terminal antenna in vertical polarization and horizontal polarization.
[0082] According to the multipath parameter list extracted from the existing network environment, the multipath polarization complex gain is determined to include: vertical polarization complex gain and horizontal polarization complex gain. The multipath polarization complex gain includes the comprehensive effect of the base station's beamforming and the transmission environment, which can be equivalent to the following formula: Formula 14 in, represents the vertical polarization complex gain of the lth path in the kth port; represents the horizontal polarization complex gain of the lth path in the kth port; the other letters in formula 14 have been introduced above and will not be repeated here.
[0083] For communication data such as 5G data reception, the terminal needs to obtain the response information of the broadband frequency domain at the corresponding frequency for subsequent channel estimation, channel equalization, decoding and other processes. The first channel response data in the frequency domain from the kth port to the uth terminal antenna at the qth frequency point generated based on the existing network wireless channel parameters can be expressed as Formula 5: Formula 5:
[0084] According to Formula 5 and Formula 13, Formula 5 in this solution is a wireless channel generated based on the existing network channel parameters and the terminal radiation pattern, and Formula 13 is the wireless channel perceived by the terminal in the existing network environment. Formula 13 can obtain all elements except the first complex radiation pattern of the terminal antenna, that is, it can fully represent the channel from the base station to the terminal (except the first complex radiation pattern of the terminal). Therefore, Formula 5 can be used to directly calculate the first channel response data. The wireless channel generated based on the method of Formula 5 is consistent with the channel environment perceived by the terminal in the existing network environment. The channel data calculated by Formula 5 can be directly used for training and verification of the AI model.
[0085] Step D2: Using the first channel response data as the first channel data of the terminal antenna.
