In recent years, many novel wireless transmission technology researches are emerging, including eddy electromagnetic wave technology (OAM) carrying orbital angular momentum. In the vortex electromagnetic wave technology, when two devices communicate, the available modes are various, and the modulation modes corresponding to different modes are different. Therefore, the receiving end needs to determine the mode used for receiving the data, and then can determine the demodulation mode according to the determined mode. However, the wave front phases of the OAM vortex waves are distributed spirally, and present period transformation on different space azimuths according to different modes, so that the sampling position of the receiving antenna may be in a phase jump region, and therefore, the phase wave front corresponding to the electromagnetic wave presents a spiral shape, so that when the antenna of the receiving end may generate phase jump, the mode detection error is larger, and the accuracy of the mode detection is reduced.

Detailed Description

The embodiment of the application discloses a communication method, a communication device and a computer-readable storage medium, which are used for improving the accuracy of modal detection. The following are detailed descriptions.

To facilitate an understanding of the present application, relevant technical knowledge related to embodiments of the present application will be first introduced herein.

In the wireless transmission technology, OAM is a vortex electromagnetic wave technology, and the phase front of OAM has a spiral shape, which results in a spatially spiral phase distribution characteristic. The phase factor of the phase distribution function of an OAM electromagnetic wave may be expressed as e^jl ^θ. θ is the attitude, i.e., the azimuth. l represents the available quantum topological charge of the vortex electromagnetic wave, i.e. the mode of the OAM, i.e. the order of the OAM, which is subsequently referred to as the mode value of the OAM. Because the OAM of different modes are mutually orthogonal, the vortex electromagnetic waves of different modes can be used as an orthogonal base of signal modulation to complete modulation. OAM is a carrier of information, and a mode of OAM needs to be detected. The PGDM is used as an algorithm for OAM modal detection, and its basic idea is: the receiving end can measure the mode of OAM according to the ratio of the included angle of the OAM detection antenna measured by the detection antenna.

Fig. 1 is a schematic diagram of an antenna arrangement disclosed in an embodiment of the present application. As shown in fig. 1, when the receiving end is provided with 2 detecting antennas, i.e., detecting

antennas

1 and 2, the detecting

antennas

1 and 2 may be distributed on a circle with a center at O. The receiving end can measure the phase of the electric field component at the corresponding position through the detecting antenna 1

The receiving end can measure the phase of the electric field component at the corresponding position through the detection antenna 2

The included angle formed by the two detection antennas and the axis connecting line is beta, and the formula for determining the mode l through the PGDM can be expressed as follows:

considering a sector spanning an angle of 180 deg. of the two detection antennas, according to the nyquist sampling theorem, forThe phase difference obtained by odd mode measurement is 180 degrees, the phase difference obtained by even mode measurement is 360 degrees, in this case, the mode can only be judged to be odd or even, and accurate judgment cannot be further carried out, so that the included angle needs to satisfy beta < pi/| l |. When the electromagnetic wave is generated by a small dipole antenna or a half-wave dipole antenna, the mode can be accurately determined by PGDM. However, when

And with

When the difference between the two is large, the phase of the electric field component jumps, and the detected modal error is large, so that the modal detection accuracy is low.

When the receiving end is provided with N detection antennas, namely the detection antenna 1, the detection antenna 2, and the detection antenna N, the N detection antennas may be distributed on a circle with O as the center of a circle. The detection antenna 1, the detection antenna 2 and the detection antenna N can respectively measure the corresponding electric field component phase

The included angles formed by the N detection antennas and the axis connecting line of the N detection antennas are different, and the mode detection can be carried out in different modes. N is an integer greater than 2.

Fig. 2 is a schematic diagram of another antenna arrangement disclosed in the embodiment of the present application. As shown in fig. 2, the receiving end may determine that the included angles between two adjacent detecting antennas may be β, respectively₁₂、β₂₃、......、β_N-1N. The formula for determining the mode i by PGDM can be expressed as follows:

wherein N is_rTo detect the number of antennas, N1_r-1，m＝2，...，N_r. Compared with two detection antennas, the modal detection result of the N detection antennas can be understood as perAnd averaging the modal detection results of the detection antennas in the group pair.

Fig. 3 is a schematic diagram of another antenna arrangement disclosed in the embodiment of the present application. As shown in fig. 3, the receiving end may determine the included angles formed by two detecting antennas spaced by one detecting antenna and the axis, which may be β respectively₁₂、β₂₃、......、β_N-1N. The formula for determining the mode i by PGDM can be expressed as follows:

the result of the modal detection with the number of the detection antennas larger than 2 is higher than the accuracy rate with the number of the detection antennas being 2. However, when the number of detection antennas is greater than 2, since there is a case where the difference in the phases of the electric field components of the partial detection antennas is large, the accuracy of the mode detection result is low.

When the detection antenna is in a certain area, the phase of the electric field component detected by the detection antenna jumps. When the phases of the electric field components corresponding to the pair of detection antennas jump, the region where the pair of detection antennas are located is a non-detection region. When the phases of the electric field components corresponding to a pair of detection antennas do not jump, the area where the pair of detection antennas are located is the detection area. The phases of the electric field components corresponding to the pair of detection antennas jump, and the phases can be understood to be turned. When the detection antenna is in a non-detection area, the accuracy of modal detection is low due to the jump of the phase of the electric field component. For example, when the phase of the electric field component corresponding to a pair of detecting antennas jumps from pi to-pi, the phase of the electric field component no longer exhibits a smooth change. Since PGDM can only perform mode estimation for smoothly varying electric field component phases, the mode in the non-detection region cannot be determined. Therefore, how to detect the mode in the non-detection area is an urgent technical problem to be solved.

In order to better explain the communication method disclosed in the embodiments of the present application, the idea of the present application is described first. Fig. 4 is a schematic diagram illustrating a comparison of PGDMs before and after a modulo operation according to an embodiment of the present application. As shown in fig. 4 (a), when performing modulo operation on the phase of the electric field component of the mode 1, under the condition of keeping the original phase information characteristic of the electric field component unchanged, the jump position of the phase of the electric field component shifts rightward, and the range of the value of the phase of the electric field component changes from the original [ -pi, pi ] to [0, pi ]. Under the condition that the position of the detection antenna is kept unchanged (namely the azimuth angle theta value is unchanged), the region where the detection antenna is located is changed from a non-detection region to a detection region, and modal detection can still be carried out. This application can detect every electric field component phase place that detection antenna corresponds earlier on the basis of PGDM algorithm originally, later can confirm according to electric field component phase place that detection antenna is in detection area or non-detection area, when detection antenna is in non-detection area, can carry out the modulus operation to electric field component phase place, can guarantee that the electric field component phase place after the modulus that detection antenna corresponds presents smooth continuous variation for detection antenna place region is changed into detection area by non-detection area. As shown in fig. 4 (b), when the mode is 1, the maximum mode value for PGDM mode detection performed directly is about 70, and the maximum mode value for PGDM mode detection performed after performing a modulo operation on the electric field component phase is about 35. Therefore, the PGDM mode detection result obtained by performing the modulus operation on the electric field component phase is higher in accuracy than the PGDM mode detection result directly performed. Before PGDM modal detection, the method can judge which modal electric field component phases are turned, and then can perform modular operation on the turning electric field component phases, so that the accuracy of modal detection can be improved.

The first device may first determine the available modalities of the second device. The second device available modality is a modality available for communication with the second device among the modalities of the first device. The first device may then send the first information to the second device. The number of the first information may be plural. The number of the first information may be the number of available modalities of the second device at most, that is, the first device sends the first information to the second device using different modalities, respectively, that is, the first information sent to the second device by the first device is information modulated by using modulation modes corresponding to the different modalities.

The first device may determine available modalities for the second device based on the angle information. The first device may determine a second modality according to the included angle information, where the second modality is a modality with a maximum modality value among the available modalities of the second device. The first device may then determine a second device available mode according to the second mode and the antenna array subset number of the first device, that is, the second mode and a mode having an absolute value smaller than a mode value of the second mode are determined as the second device available mode. The angle information is information of an angle between antennas that perform communication between the second device and the first device.

Under the condition that the included angle information is stored in the first device, the first device may first obtain the stored included angle information. Under the condition that the included angle information is not stored in the first device, the first device can acquire the included angle information from the second device. The second device may first determine the angle information and may then send the angle information to the first device. After the first device receives the angle information from the second device, the available modalities of the second device can be determined according to the angle information. In one case, fig. 9 is a schematic diagram of a transmission system disclosed in the embodiment of the present application. As shown in fig. 9, when the second device is provided with 2 detection antennas, the included angle information may be β corresponding to the two detection antennas. In another case, fig. 10 is a schematic diagram of another transmission system disclosed in the embodiments of the present application. As shown in fig. 10, when the second device is provided with N detection antennas, the included angle information may include β corresponding to each of the plurality of pairs of detection antennas formed by the N detection antennas. Modal value l of the second mode_maxCan be expressed as

The modal value of the available modality of the second equipment can be | l | ≦ l_max. When the number of antenna arrays of the first device is f, the corresponding modal value may be determined to be-f/2 ≦ l < f/2. The range of modal values of the available modality of the second device may be | l ≦ l_maxAnd l is more than or equal to f/2 and less than f/2. For example, when the modal value of the second modality is l_maxWhen 3 states and the antenna of the first device is 4, the mode values of the available modes of the second device may be-2, -1, and 0. It should be understood that when the second device is provided with 2 detection antennas, β may be an included angle corresponding to two detection antennas on the second device. When the second device is provided with N antennas, β may be an included angle corresponding to any pair of detection antennas on the second device, may also be an included angle corresponding to all pairs of detection antennas on the second device, and may also be an included angle corresponding to a part of detection antennas on the second device.

The first device may periodically send first information corresponding to each of the available modalities of the second device to the second device. Fig. 11 is a schematic diagram of transmission of first information disclosed in an embodiment of the present application. As shown in fig. 11, during a period T, the first device may send first information corresponding to each modality available for the second device to the second device. In one case, the value of the period T may be determined as desired. In another case, the first device may determine the period T according to the angle information of the second device. The period T may be

Wherein β is one of the included angles included in the included angle information, and may be a maximum included angle among the included angles included in the included angle information, or a minimum included angle among the included angles included in the included angle information, or an optimal included angle selected from the included angles included in the included angle information according to the steering information. For example, an angle corresponding to a pair of detection antennas that do not turn is better than an angle corresponding to a pair of detection antennas that do turn, and in the case that there are multiple pairs of detection antennas that do not turn, β may be a minimum angle among the angles corresponding to the multiple pairs of detection antennas. r is the radius of the detecting antenna of the second device, and β r is the radius of the two detecting antennasAnd v is the speed of movement of the second device about the axis of the antenna.

The first device may periodically send first information to the second device corresponding to each of the available modalities of the second device. Fig. 12 is a schematic diagram of another transmission system disclosed in the embodiments of the present application. As shown in fig. 12, when the detecting antenna of the second device is slowly rotated along the axis, the phases of the electric field components measured by the detecting antenna on the second device at different times may be different. Accordingly, the steering information is different at different times. Therefore, in order to ensure timeliness of the steering information, the first device can periodically send the first information to the second device, so that the second device can periodically measure the steering information, the steering information can be timely updated when the steering information is sent and changed, success rate of modal detection can be improved, and accuracy of modal detection can be ensured.

Fig. 13 is a schematic diagram of another transmission of the first information disclosed in the embodiment of the present application. As shown in fig. 13, during one period T, the first device may send first information corresponding to each of the available modalities of the second device to the second device. After receiving the steering information from the second device, the first device may determine whether the steering information corresponding to each modality is determined to be successful, and when the determination is determined to be successful, the first device may not send the first information corresponding to the modality to the second device in a next period. However, since the detection antenna of the second device is rotated, assuming that the steering information corresponding to the mode 1 is successfully measured in the 1 st cycle, in order to ensure the validity of the steering information, the nth cycle is required_T+1 cycle the corresponding steering information for model 1 is measured again. N is a radical of_TIs composed of

Where M is the number of modalities included in the second device's available modalities. The first device can send the first information corresponding to the undetermined steering information mode, and the times of sending the first information can be reducedThe method can save channel resources and improve the modal detection efficiency.

The first device may send second information to the second device, the second information being usable to determine a modality used by the first data, the first data being data for which the modality has not been determined by the second device.

802. The second device determines steering information from the first information.

After the second device receives the first information, steering information may be determined based on the first information. The second device may detect the phase of the electric field component corresponding to each of all pairs of detecting antennas on the second device when the first information is received. The second device may then determine steering information based on the phase of the electric field component corresponding to each of all pairs of sensing antennas. The second device may determine whether an electric field component phase corresponding to each pair of detection antennas in all the pairs of detection antennas jumps, and when it is determined that the electric field component phase corresponding to the first pair of detection antennas jumps, which indicates that the first pair of detection antennas is in a non-detection area, may determine steering information corresponding to the first pair of detection antennas as a first threshold. When it is determined that the phase of the electric field component corresponding to the first pair of detection antennas does not jump, indicating that the first pair of detection antennas is in the detection area, the steering information corresponding to the first pair of detection antennas may be determined as the second threshold. The first pair of detection antennas is any one of all pairs of detection antennas on the second device. The first threshold and the second threshold are preset values, the first threshold is used for indicating that the phases of the electric field components corresponding to the first pair of detection antennas jump, and the second threshold is used for indicating that the phases of the electric field components corresponding to the first pair of detection antennas do not jump.

Each of the first information may correspond to one of the available modalities of the second device, and therefore, the second device needs to determine the steering information according to the first information corresponding to each of the available modalities of the second device. The same way of determining the steering information corresponding to different modalities can be referred to the above description of the first pair of detection antennas.

As shown in fig. 9, when the number of the detection antennas in the second device is 2, the electric field of the detection antenna 1The phase of the component may be

The phase of the electric field component of the detecting antenna 2 may be

The second device can judge

whether the absolute value of the difference between the two is within the range of pi and 2 pi is judged

And

whether or not to satisfy

When the electric field component phase is judged to be out of the range of pi and 2 pi, the electric field component phase of the pair of detection antennas can be determined to jump when receiving the first information, and when the electric field component phase is judged to be in the range of pi and 2 pi, the electric field component phase of the pair of detection antennas can be determined not to jump when receiving the first information.

As shown in fig. 10, when the number of the detecting antennas in the second device is N, the second device may first determine each pair of detecting antennas in all pairs of detecting antennas on the second device, and then may determine the steering information corresponding to each pair of detecting antennas according to the first information, so that the steering information may be determined according to the first information, and the detailed description may refer to the above related description. The phases of the electric field components corresponding to a pair of detecting antennas are respectively

Then (c) is performed. The detailed description may refer to the related description above.

It should be understood that the steering information may include steering information for detecting certain first information of the antenna pair. According to the characteristics of OAM, when the variation range of the azimuth angle θ is [0, 2 π ], the amplitude of the jump increases with the increase of the OAM mode, i.e., the phase variation of the electric field component is accelerated as the mode is larger. Thus, the larger the modality, the more accurate the steering information determined by the second device. After the second device determines the steering information, the steering information may be sent to the first device. The first device may determine whether the phase of the electric field component of the corresponding modality is steered, according to the steering information.

803. The second device determines a modulo factor from the steering information.

After the second device determines the steering information according to the first information, the modulus factor may be determined according to the steering information.

In one case, the second device may send steering information to the first device. After the first device receives the steering information from the second device, a modulo factor may be determined from the steering information, and the determined modulo factor may then be transmitted to the second device. The first device may first determine whether each piece of steering information corresponding to the first information is a first threshold, and when it is determined that the piece of steering information is the first threshold, it indicates that a detection antenna pair corresponding to the piece of steering information generates a jump in an electric field component phase when receiving the first information, and may determine a modulus factor corresponding to the piece of steering information according to an included angle corresponding to the pair of detection antennas and a modal value of the piece of steering information. The modulus taking factors of different modes corresponding to the same pair of detection antennas may be different.

In another case, after the second device determines the steering information according to the first information, the modulus factor may be determined directly according to the steering information. The detailed description may refer to the above description. The second device also needs to obtain modality values of modalities among available modalities of the second device from the first device. The modality value may include a modality value of a first modality corresponding to the first information, where the first modality is any one of the modalities available for the second device. The first modality may be the second modality, may be a modality corresponding to the first information in which the steering has occurred, or may be a modality corresponding to all the first information. The modal value corresponding to the steering information may be carried in the first information corresponding to the steering information, and the modal value of the steering information may also be obtained by the second device. After the second device determines the steering information according to the first information, the second device may send the steering information to the first device, and after the first device receives the steering information, the first device may determine a mode corresponding to the steering information, and then may send a mode value of the mode to the second device.

The modulus factor ε can be expressed as

Beta is less than or equal to

For example, β is π/4, the second device can use modes with modal values of 2, -2, 1 and-1, and modes with modal values of-2 and 2 have been steered with respect to the phase of the electric field component. The mode values l are 2 and-2, after which the modulus factors for the mode values 2 and-2 can be calculated to be both 1.

It should be understood that the second information in the claims is the modulus factor or modal value described above.

After the first device or the second device determines the modulus factor, a modulus identifier may be determined for the modulus factor corresponding to each modality. For example, the modality values of the available modalities of the second device are 2, -2, 1 and-1, and the modality-2 and the modality 2 are turned, and the modulus identification may be determined for the modulus factors corresponding to the modality-2 and the modality 2. The modulus identifiers corresponding to different modes can be the same or different. After the first device or the second device determines the modulus identifier corresponding to each modality, the modulus identifier corresponding to each modality may be sent to the opposite terminal.

804. The first device sends first data to the second device.

The first device may send the first data to the second device, and correspondingly, the second device may receive the first data from the first device. Before or at the same time of sending the first data to the second device, the first device may send a modulo identity or a modulo factor corresponding to a modality used for sending the first data to the second device. For example, the first data may carry a modulus identifier or a modulus factor corresponding to a mode used by the first data. The first data may be an OAM vortex electromagnetic wave signal.

The modulus factor is determined by the first device or the second device, and may be pre-configured, default configured, or determined by the first device.

Fig. 14 is a schematic diagram illustrating determination of a modulus factor according to an embodiment of the present application. As shown in fig. 14, the modulus factor determination method may include the steps of:

1401. the first device sends a determination indication to the second device.

The modulus factor is determined by the first device or the second device, and can be determined according to the requirement of the current transmission service. When the requirements for transmission services are different, the devices that can be selected may also be different. Where this is determined by the first device, the first device may first determine whether the modulus factor is determined by the first device or the second device. The first device may then send a determination indication to the second device. The determination indication is indicative of a determination of the modulo factor by the first device or the second device. The corresponding determination indication of fig. 14 is used to indicate that the modulo factor is determined by the first device.

1402. The second device transmits Acknowledgement (ACK) information to the first device.

The second device may send ACK information to the first device after successfully receiving the determination indication from the first device.

After the first device receives the ACK information or after sending the determination indication to the second device, when the determination indication indicates that the modulo factor is determined by the first device, the modulo factor may be determined according to the steering information.

1403. The first device sends first data to the second device.

The first device may send the first data to the second device after receiving the ACK information from the second device. The first data carries a modulus factor corresponding to a mode used by the first data.

Fig. 15 is a schematic diagram of another modulo factor determination disclosed in the embodiments of the present application. As shown in fig. 15, the modulus factor determination method may include the steps of:

1501. the first device sends the modal values of the modalities in the available modalities of the second device to the second device.

The mode value of a mode in the available modes of the second device may be a mode value of each mode in the available modes of the second device, may also be a mode value of one mode in the available modes of the second device, and may also be a mode value of a part of modes in the available modes of the second device. This mode may be the second mode, or may be other modes, which is not limited herein.

1502. The second device sends the first ACK information to the first device.

After the second device successfully receives the modal value from the first device, first ACK information may be sent to the first device.

1503. The first device sends an acknowledgement indication to the second device.

After the first device receives the first ACK information from the second device, or at other times, an acknowledgement indication may be sent to the second device. The acknowledgement indication here is used to indicate that the modulo factor is determined by the second device.

1504. The second device sends second ACK information to the first device.

The second device may send second ACK information to the first device after successfully receiving the determination indication from the first device. Meanwhile, the second device may further determine whether the second device determines the modulo factor according to the determination indication, and when it is determined that the second device determines the modulo factor, the second device may determine the modulo factor according to the steering information.

1505. The first device sends first data to the second device.

The first device may transmit the first data to the second device after receiving the second ACK information from the second device. The first data carries a modulus identification corresponding to a mode used by the first data.

When the first device sends the modal value of each modal in the available modalities of the second device to the second device, the modalities used by the first data are different, and the corresponding modulo identifiers are different. When the first device sends the modal value of one of the available modalities of the second device to the second device, the modalities used by the first data are different, and the corresponding modulo identities are the same, that is, the modulo identities corresponding to all the modalities of the available modalities of the second device are the same, that is, the modulo factors corresponding to all the modalities of the available modalities of the second device are the same.

805. And the second equipment determines the mode used by the first data according to the modulus factor.

After the second device receives the first data, the mode used by the first data can be determined according to the modulus factor. The second device may first determine a modulus factor corresponding to a modality used for the first data. For example, the modulus factor corresponding to the modality used by the first data may be determined according to the modulus factor or the modulus identifier carried by the first data. And then the second device can determine the mode used by the first data according to the modulus factor corresponding to the mode used by the first data. The second device may perform a modulo operation on the phase of the first data according to a modulo factor corresponding to the mode used by the first data, and then may determine the mode used by the first data according to a result of the modulo operation and the PGDM. The phase of the first data may be understood as the phase corresponding to different pairs of detecting antennas when the second device receives the first data.

It should be understood that the phases in the claims are the phases of the electric field components.

After the second device receives the first data, it may be determined whether a modulus factor corresponding to a mode used by the first data exists, and when it is determined that the modulus factor corresponding to the mode used by the first data exists, it indicates that the mode used by the first data in the detection antennas of the second device corresponds to one or more pairs of detection antennas in a non-detection region, and the mode used by the first data may be determined according to the modulus factor. When it is determined that the modulo factor corresponding to the mode used by the first data does not exist, it is indicated that the mode used by the first data in the detection antennas of the second device corresponds to all pairs of detection antennas in the detection region, and the mode used by the first device may be directly determined according to the PGDM.

In a possible situation, the second device may determine whether the first data carries a modulo factor or a modulo identity, and determine that a modulo operation needs to be performed on a phase of the first data when the second device determines that the first data carries the modulo factor or the modulo identity.

The modulo operation can be expressed as

μ may be represented as the first number receivedDepending on the magnitude of the amplitude values,

may be expressed as an offset of the phase of the electric field component from the phase of the first electric field component at which the first data is received. The first electric field component is relatively fixed in phase. γ can be expressed as the number of cycles over which θ varies, as

Can be expressed as

θ may vary between 0 ° and 359 °.

Is the phase of the electric field component of the first data,

the phase of the electric field component of the first data corresponding to the mode measured by an antenna in the corresponding pair of detecting antennas may be determined, or an average value or a median value of the phases of the electric field components measured by a plurality of antennas may be determined. For example, a value of μ ═ 0.5,

ε is 1. When the number of the detection antennas in the second device is 2, the mode value of the mode used for the first data may be

Wherein. Beta' is the result of the modulo operation.

And

the two detection antennas respectively correspond to the electric field component phases when receiving the first data. When in useWhen the number of the detection antennas in the second device is N, different pairs of detection antennas in the non-detection area have different modulo factors, and accordingly, modulo operation can be performed on different pairs of detection antennas in the non-detection area. The first data has a modal value of a mode

It may represent the result of a modulo operation of a pair of detection antennas, n and m, of the second device detection antenna. The pair of n and m detection antennas may be any one of all pairs of detection antennas formed in the second device.

Fig. 16 is a schematic diagram of a performance analysis of a mode detection according to an embodiment of the present application. As shown in fig. 16, the horizontal axis represents a signal to noise ratio (SNR) and the vertical axis represents a Bit Error Rate (BER). The unit of SNR is decibels (dB). As can be seen from the results of the modes 1 to 4, the error rate is the greatest when the mode detection is performed directly using the PGDM. With the same SNR, the BER decreases as the modulo factor increases. The larger the SNR, the smaller the BER, with the same modulo factor. When the mode detection is directly carried out by using the PGDM, the BER hardly changes along with the change of the SNR, which indicates that the PGDM has good anti-interference capability.

Fig. 17 is a schematic diagram illustrating a performance analysis of another modality detection disclosed in the embodiment of the present application. As shown in fig. 17, as the SNR increases, the detection success rate (SDR) increases. When SNR is the same, SDR directly passing through PGDM detection mode is smaller than most of the method of firstly taking module and then PGDM. Therefore, it can be shown that the method of taking the modulus first and then PGDM is superior to the method of detecting the modality directly by PGDM. Under the condition of the same modulus factor, the SDR is firstly increased along with the increase of the SNR and then is kept unchanged, which indicates that SDRs corresponding to different channels have a saturation value.

Referring to fig. 18, based on the network architecture, fig. 18 is a schematic flowchart of another communication method disclosed in the embodiment of the present application. As shown in fig. 18, when the number of the detection antennas in the second device is 2, the transmission system between the first device and the second device may be as shown in fig. 9, and the communication method may include the following steps.

1801. The first device sends the first information to the second device.

The detailed description of step 1801 may refer to the description of step 801, and is not repeated herein.

After determining the available modality of the second device, the first device may send the first information to the second device randomly, that is, the modality corresponding to the first information sent each time is random, but the first information corresponding to the same modality is sent only once. When the first information is transmitted to the second device, the first information may be transmitted in a certain order. For example, the corresponding first information may be transmitted in order of a large to small or a small to large modal value.

1802. The second device determines steering information from the first information.

After the second device receives the first information from the first device, phase information of the first information may be determined. For a detailed description of step 1802, reference may be made to the related description that the number of the detection antennas in the second device is 2 in step 802, which is not described herein again.

1805. The second device sends the steering information to the first device.

After the second device determines the steering information, the second device may send the steering information to the first device. The second device may send the angle information to the first device along with the steering information. For example, steering information may be carried in angle information, or angle information may be carried in steering information. Because the different included angles corresponding to the detection antennas in the second device are fixed and unchangeable, the second device only needs to send included angle information to the first device once, so that the transmitted information can be reduced, and transmission resources can be saved. The steering information may be steering information corresponding to all modalities in the available modalities of the second device, that is, after the steering information corresponding to all modalities in the available modalities of the second device is determined, the steering information may be sent to the first device at one time, so that the number of times of information transmission may be reduced, and transmission resources may be saved. The steering information may also be the steering information corresponding to one of the available modalities of the second device, that is, the steering information corresponding to one of the available modalities of the second device is sent once when the second device determines that the second device is in the available modality. The steering information sent by the second device to the first device may also carry information of the corresponding first information, so that after the first device receives the steering information, the modality corresponding to the steering information may be determined. The detailed description of the steering information may refer to the description of step 802.

1806. And the first equipment determines the available modes of the second equipment according to the included angle information.

The detailed description of step 1806 may refer to the related description in step 801, which is not repeated herein.

1807. The first device determines a modulo factor from the steering information.

The detailed description of step 1807 may refer to the related description in step 803, which is not repeated herein.

1808. The first device sends first data to the second device.

After the first device determines that the second device is available, the first device may send the first data to the second device. For example, the modality values of the available modalities of the second device are-1, -2, and 2. The first device may send a modality value of the available modality of the second device to the second device using two bits. For example, the correspondence between information bits and modality values may be as shown in table 1:

TABLE 1

Information bit	Modal value of a modality
		00	-1
01	1
		11	2
10	-2

As shown in table 1, the mapping relationship between the corresponding information bits and the mode values of the modes may represent a manner in which the bit data stream is mapped to the different mode vortex waves of the OAM. It should be understood that the above is an example of the mapping relationship between the information bits and the mode values of the modes, and is not limiting.

1809. And the second equipment determines the mode used by the first data according to the modulus factor.

The detailed description of step 1809 may refer to the related description in step 805, and is not repeated herein.

Referring to fig. 19 based on the network architecture, fig. 19 is a flowchart illustrating another communication method according to an embodiment of the present disclosure. As shown in fig. 19, when the number of the detection antennas in the second device is N, the transmission system between the first device and the second device may be as shown in fig. 10, and the communication method may include the following steps.

1901. The first device sends the first information to the second device.

Fig. 20 is a schematic diagram of another transmission system disclosed in the embodiment of the present application. As shown in fig. 20, the antennas of the second device may be arranged in a circle or in a lattice. When the first device sends the first information, the second device may detect whether the antenna arrangement of the first device and the antenna arrangement of the second device are on the same axis, and when the antenna arrangement of the first device and the antenna arrangement of the second device are not on the same axis, the first device and/or the second device may perform adjustment. For example, the axes of the antenna arrays may be adjusted to the same axis by the first device and the second device, or the electromagnetic field may be calculated according to the axis estimation information, so that the axes of the first device and the second device are completely calibrated, and the accuracy of the mode detection may be further improved.

The detailed description of step 1901 may refer to the descriptions of steps 801 and 1801, which are not repeated herein.

1902. The second device determines steering information from the first information.

The second device may determine the steering information after receiving the plurality of first information from the first device. When different pairs of detection antennas have different corresponding steering information under different modes, the steering information may be different. For example, the relationship of steering information, modality, and β may be as in table 2:

TABLE 2

As shown in table 2, in the case of β and modality determination, steering information is determined accordingly. A "1" in table 2 may indicate that the phase of a mode is steered in this detection antenna pair, and a "0" may indicate that the phase of a mode is not steered in this antenna pair. The second device may determine table 2 and send the angle information and steering information of table 2 to the first device.
