[0043] In order to more clearly understand the above-mentioned objectives, features and advantages of the present disclosure, the scheme of the present disclosure will be further described below. It should be noted that the embodiments of the present disclosure and the features therein can be combined with each other in the absence of conflict.

[0044] In the following description, many specific details are set forth to facilitate a full understanding of the present disclosure, but the present disclosure may also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present disclosure, rather than all of the embodiments.

[0045] Currently, in relay equipment, if beamforming is required, the entire baseband system often needs to be integrated, which greatly increases the complexity, volume and cost of the relay equipment, making it difficult to deploy relay equipment on a large scale.

[0046] To support the large-scale application of millimeter wave technology in the 5G field and reduce the complexity, volume, and cost of relay equipment, the present disclosure provides a millimeter wave signal processing method, apparatus, millimeter wave relay equipment, and storage medium. Below, we first introduce the millimeter wave signal processing method provided by the present disclosure.

[0047] The millimeter wave signal processing method provided in the present disclosure is applied to a millimeter wave relay device, which includes at least a core module with logic processing capabilities and a millimeter wave antenna. The millimeter wave signal processing method provided in the present disclosure can be implemented by at least one of software, hardware circuits and logic circuits set in the millimeter wave relay device.

[0048] like Figure 1 As shown, a millimeter wave signal processing method provided by the present disclosure may include the following steps.

[0049] S101: Acquire a millimeter wave signal.

[0050] S102: Extract signal characteristics of the millimeter wave signal, analyze the signal characteristics, and determine whether a millimeter wave connection is established between the base station and the user equipment.

[0051] S103: If a millimeter wave connection is not established between the base station and the user equipment, control the millimeter wave antenna to perform beamforming.

[0052] By applying the embodiments of the present disclosure, the signal characteristics of the millimeter wave signal are extracted and analyzed to determine whether a millimeter wave connection is established between the base station and the user equipment. If a millimeter wave connection is not established between the base station and the user equipment, the millimeter wave antenna is controlled to perform beamforming. Beamforming is a signal preprocessing technology based on an antenna array. It can generate a directional beam by adjusting the weighting coefficient of each array element in the millimeter wave antenna array to perform array gain. It has great advantages in expanding coverage, improving edge throughput, and suppressing interference. Therefore, the present disclosure overcomes the problems of high propagation loss of millimeter waves, weak diffraction and diffraction capabilities, and relatively limited coverage, and provides support for the large-scale application of millimeter wave technology in the 5G field.

[0053] Millimeter-wave relay equipment is primarily used to process 5G millimeter-wave signals. After powering on, the millimeter-wave relay extracts millimeter-wave signals from the millimeter-wave RF link and uses feature extraction to identify the millimeter-wave signal's characteristics. These signal characteristics can be physical characteristics such as time domain characteristics, frequency domain characteristics, and power characteristics, or they can be a fusion of multiple characteristics.

[0054] After extracting the signal features, they are analyzed. Based on this analysis, it can be determined whether a millimeter wave connection has been established between the base station and the user device. A millimeter wave connection is considered established between the base station and the user device if the signal features meet certain requirements, such as analyzing the magnitude of each component of the signal features, fluctuations within a preset period, and whether the signal amplitude meets a preset threshold.

[0055] In addition, based on the extracted signal features, it is also possible to determine whether a millimeter wave connection is established between the base station and the user equipment by mapping a difference table, comparing with historical feature data, and the like.

[0056] In one implementation of the embodiment of the present disclosure, the step of analyzing the signal characteristics in S102 to determine whether a millimeter wave connection has been established between the base station and the user equipment can specifically be: comparing and analyzing the signal characteristics with the stored characteristic data of establishing a millimeter wave connection between the base station and the user equipment; and judging whether a millimeter wave connection has been established between the base station and the user equipment based on the comparison and analysis results.

[0057] The millimeter wave relay device has an internal storage function that stores feature data of millimeter wave connections established between base stations and user devices. These feature data are historical signal features of millimeter wave connections established between base stations and user devices, or feature data trained offline based on historical signal features. The specific process of analyzing the signal features can be to compare and analyze the signal features with the stored feature data of millimeter wave connections established between base stations and user devices. If the similarity between the signal features and any of the stored feature data is greater than a preset similarity threshold, it indicates that a millimeter wave connection has been established between the base station and the user device; if the signal features are not similar to any of the stored feature data, it indicates that a millimeter wave connection has not been established between the base station and the user device.

[0058] Optionally, the stored feature data for establishing a millimeter wave connection between the base station and the user equipment is obtained through offline self-learning training.

[0059] The characteristic data of the millimeter wave connection established between the base station and the user equipment stored in the millimeter wave relay device can be obtained through offline machine learning methods. First, the signal characteristics when the millimeter wave connection has been established are recorded, and these signal characteristics are self-learned offline. After a large number of training processes, the characteristic data is finally obtained for loading and storage.

[0060] In another implementation of the embodiment of the present disclosure, the step of analyzing the signal characteristics in S102 to determine whether a millimeter wave connection has been established between the base station and the user equipment can be specifically as follows: based on the signal characteristics, searching from the mapping relationship between "signal characteristics obtained by online learning" and "whether a millimeter wave connection has been established" to obtain a search result of whether a millimeter wave connection has been established between the base station and the user equipment corresponding to the signal characteristics.

[0061] The millimeter wave relay device can also have the function of online learning. With the assistance of external equipment, it can learn the mapping relationship between signal characteristics and "whether a millimeter wave connection has been established". Therefore, after extracting the signal characteristics, it can be used to find out from the mapping relationship whether a millimeter wave connection has been established between the base station and the user equipment corresponding to the signal characteristics.

[0062] If analysis determines that no millimeter wave connection is established between the base station and the user equipment, beamforming is required. By controlling the direction, gain, etc. of the millimeter wave antenna, the millimeter wave signal is directed to different positions in space within a certain shape space, that is, to positions different from those where the millimeter wave connection is not established. Steps S101-S103 are performed again until a millimeter wave connection is established between the base station and the user equipment.

[0063] Millimeter-wave antennas include donor-side millimeter-wave antennas and coverage-side millimeter-wave antennas. Millimeter-wave relay devices can use corresponding strategies to initiate beam scanning. For example, if the millimeter-wave relay device is used for enhanced indoor millimeter-wave coverage, the base station and millimeter-wave relay device are relatively fixed. Therefore, once the beamforming strategy of the donor-side millimeter-wave antenna is determined, it can be adjusted in real time until the next power-on; beam scanning can be triggered through external control. Of course, if the location of the user device is also relatively fixed, once the beamforming strategy of the coverage-side millimeter-wave antenna is determined, it can be adjusted in real time until the next power-on; beam scanning can be triggered through external control.

[0064] In a specific implementation, in one implementation of the embodiment of the present disclosure, the millimeter wave antenna includes a donor side millimeter wave antenna and a coverage side millimeter wave antenna, wherein the donor side millimeter wave antenna is used to perform beam scanning and locking operations, and the coverage side millimeter wave antenna is used to perform wide beam coverage operations.

[0065] In the case where the user equipment has a mobile characteristic, the coverage-side millimeter wave antenna adopts a wide-beam coverage mode. Accordingly, the step of controlling the millimeter wave antenna to perform beamforming in S103 may specifically be: controlling the donor-side millimeter wave antenna to perform beamforming.

[0066] If the user device is mobile, such as a mobile phone or smart watch, a wide beam can be used on the coverage side to eliminate the beamforming process. In this way, only the donor-side millimeter wave antenna performs beamforming, increasing the probability of successfully establishing a millimeter wave connection between the base station and the user device.

[0067] based on Figure 1 The present disclosure also provides a millimeter wave signal processing method, such as Figure 2 As shown, the method may include.

[0068] S201: Acquire a millimeter wave signal.

[0069] S202, extracting signal features of the millimeter wave signal and analyzing the signal features to determine whether a millimeter wave connection is established between the base station and the user equipment. If so, execute S203, otherwise execute S204.

[0070] S203: Lock the current beamforming strategy of the millimeter wave antenna. If it is detected that the millimeter wave connection between the base station and the user equipment is invalid, the process returns to S202.

[0071] S204: Control the millimeter wave antenna to perform beamforming.

[0072] If analysis determines that a millimeter-wave connection has been established between the base station and the user device, the millimeter-wave antenna's current beamforming strategy can be locked, maintaining the current beamforming strategy and ensuring normal transmission of the millimeter-wave signal. At the same time, the beam search can be retriggered, either through a physical button on the device or wirelessly controlled by a mobile device.

[0073] If it is detected that the millimeter wave connection between the base station and the user equipment fails, it is necessary to return to S202 and re-perform beamforming, where the failure of the millimeter wave connection between the base station and the user equipment indicates that the link between the base station and the user equipment for connecting the millimeter wave signals fails.

[0074] Other steps and Figure 1 The corresponding steps of the embodiment shown are the same, and the specific contents are shown in Figure 1 The embodiments shown will not be described in detail here.

[0075] In the present disclosure, by extracting and analyzing signal features, it is possible to determine whether a millimeter wave connection is established between the base station and the user equipment, and further control the millimeter wave antenna to perform beamforming when no connection is established. The millimeter wave relay device does not need to integrate the entire baseband system, has a simple structure, low cost, automatically locks the base station position, and establishes a reliable millimeter wave connection between the base station and the user equipment, which is very conducive to productization and contributes to the large-scale application of millimeter wave technology.
