[0039] In order to make the objectives, technical solutions and advantages of the present application clearer and more understandable, the present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0040] It can be understood that the terms "first", "second", etc. used in the present application may be used in this document to describe various elements, but these elements are not limited by these terms. These terms are only used to distinguish the first element from another element, and cannot be understood as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one of such features. In the description of the present application, "a plurality" means at least two, such as two, three, etc., unless otherwise specifically defined.

[0041] The electronic device involved in the embodiments of the present application has a wireless communication function. As Figure 1 shown, the electronic device 10 can be communicatively connected to the network device 20. The electronic device 10 can be a handheld device, a vehicle-mounted device, a smart car, a wearable device, a computing device or other processing devices connected to a wireless modem, as well as various forms of user equipment (UE) (for example, a mobile phone), a mobile station (MS), and so on. For ease of description, the devices mentioned above are collectively referred to as electronic devices.

[0042] The network device 20 can be a device that communicates with the electronic device 10, can provide communication coverage for a specific geographical area, and then can communicate with the electronic device 10 located within the coverage area. Exemplarily, the network device 20 can be a mobile switching center, a relay station, an access point, a vehicle-mounted device, a wearable device, a hub, a switch, a bridge, a router, a core network in a 5G network, a base station and other network-side devices or network devices in a future evolved public land mobile network (PLMN), etc.

[0043] Figure 2 Structural block diagram of an electronic device according to an embodiment. Refer to Figure 2, in this embodiment, the electronic device 10 includes: multiple antennas (ANT1, …… ANTn respectively), a radio frequency module 110, a processing module 120, and an adjustment module 130 (in the figure, the adjustment module 130 is connected between the radio frequency module 110 and the multiple antennas as an example for illustration).

[0044] The radio frequency module 110 is connected to the multiple antennas; the processing module 120 is configured to perform time reversal based on the reception information of the reference signals received by the multiple antennas when the radio frequency module 110 receives the reference signals transmitted by the network device 20 through the multiple antennas, and obtain the phase difference and amplitude ratio of the time reversal signals transmitted between the multiple antennas; the adjustment module 130 is configured to adjust the parameters of the radio frequency signals transmitted on the target radio frequency path, and the target radio frequency path is the path between the radio frequency module 110 and at least two target antennas among the multiple antennas, so that at least two target antennas perform beamforming with the phase difference and amplitude ratio.

[0045] Among them, the multiple antennas can be distributed at different positions of the electronic device 10. For example, they can be distributed on different frames of the electronic device 10. The multiple antennas can be understood as forming a phased array antenna. In the phased array antenna, based on at least two target antennas, it supports simultaneous transmission of radio frequency signals. An antenna gain stronger transmission beam can be formed based on beamforming to improve the transmission quality; based on at least two target antennas, it can also support simultaneous reception of radio frequency signals, forming an antenna gain stronger reception beam to improve the reception quality.

[0046] Among them, the radio frequency module 110 is respectively connected to the multiple antennas, and can transmit radio frequency signals through at least two target antennas among the multiple antennas. For example, it can transmit radio frequency signals through at least two target antennas, and can receive reference signals and radio frequency signals from the network device 20 through at least two target antennas. Exemplarily, the radio frequency module 110 can include a transceiver circuit, and the transceiver circuit can support the transceiver of radio frequency signals through the connected antennas; the transceiver circuit can include a transmitting circuit and a receiving circuit, and the transmitting circuit and the receiving circuit can transmit radio frequency signals through the antennas independently connected respectively, or can transmit radio frequency signals through the multiplexed connected antennas.

[0047] It can be understood that the reference signal also belongs to the radio frequency signal. In this embodiment, the main purpose is to distinguish the signals transmitted before and after time reversal processing through the reference signal and the radio frequency signal, rather than being limited to the specific type of the signal. Exemplarily, the radio frequency signal can be a millimeter wave band signal (the frequency range is 24.25 GHz to 52.6 GHz), or a sub6GHz band signal (the frequency range of the band is 450 MHz to 6 GHz). The radio frequency signal in the sub6GHz band has a longer wavelength, can better cross obstacles, is suitable for long-distance transmission, and is applicable to the scenario where the electronic device 10 and the network device 20 are far apart; the radio frequency signal in the millimeter wave band has a shorter wavelength and is applicable to the scenario where there are more electronic devices 10 and / or network devices 20.

[0048] Among them, when the radio frequency module 110 receives the reference signal transmitted by the network device 20 through multiple antennas, the processing module 120 can receive the reference information through the radio frequency module 110, and perform time reversal processing on the received information obtained by analyzing the reference signal. The received information can include, for example, the amplitude and phase of the reference signal received by the antenna, thereby obtaining the time reversal signal, and then obtaining the phase difference and amplitude ratio required for the time reversal signal. As Figure 3 shown, the time reversal technology utilizes the symmetry of Maxwell's equations to perform time reversal processing on the recorded broadband detection information sent by the receiver and modulate the transmission with the information, so that the signal can automatically achieve time-space synchronous focusing at the receiving user and realize signal reproduction.

[0049] In this embodiment, the amplitude and phase of the time reversal reference signal are utilized to obtain the amplitude ratio and phase difference of the time reversal signal transmitted between multiple antennas. Based on the channel reciprocity, when the radio frequency module 110 and at least two target antennas connected thereto can perform beamforming with the amplitude ratio and phase difference, the radio frequency signal can be more effectively received by the network device 20, or the radio frequency signal transmitted by the network device 20 can be more effectively received, thereby improving the communication experience. Specifically, in this embodiment, the adjustment module 130 is used to adjust the parameters of the radio frequency signal transmitted on the target radio frequency path, so that the radio frequency module 110 and at least two target antennas connected thereto can perform beamforming with the amplitude ratio and phase difference. Thus, radio frequency signals with different phases will form a more strongly gain-directed beam in the air based on the principle of wave interference, and wireless communication is performed based on the formed beam.

[0050] Among them, the larger the amplitude corresponding to the antenna, the greater the contribution to the beamforming. The target antennas are at least two of the multiple antennas. The at least two antennas can be all of the multiple antennas mentioned above, or the antennas with larger amplitudes and an amplitude ratio close to 1 among the multiple antennas.

[0051] The target RF path is the path where the RF module 110 and at least two target antennas are located. The target RF path can be a transmitting path, a receiving path, or a transceiver path integrating transmitting and receiving functions. For example, when the electronic device 10 supports beamforming in transmission, the RF module 110 may include at least two transmitting circuits, and the at least two transmitting circuits are conductively connected to at least two target antennas correspondingly. The target RF path is the transmitting path where each transmitting circuit and the connected target antennas are located. When the electronic device 10 supports beamforming in reception, the RF module 110 may include at least two receiving circuits, and the at least two receiving circuits are conductively connected to at least two target antennas correspondingly. The target RF path is the receiving path where each receiving circuit and the connected target antennas are located.

[0052] The electronic device 10 provided in this embodiment includes multiple antennas, an RF module 110, a processing module 120, and an adjustment module 130. When the reference signal transmitted by the network device 20 is received, the processing module 120 performs time reversal based on the reception information of the reference signals received by the RF module 110 and the multiple antennas, and obtains the phase difference and amplitude ratio of the time-reversed signals transmitted between the multiple antennas. The adjustment module 130 adjusts the parameters of the RF signals transmitted on the target RF path based on the phase difference and amplitude ratio, so that at least two target antennas perform beamforming with the phase difference and amplitude ratio.

[0053] In the related art, it is usually necessary to perform direction-of-arrival (DOA) estimation, such as the MUSIC algorithm, which uses the orthogonality between the signal subspace and the noise subspace to estimate the DOA to determine the direction of the incoming wave. However, due to the uneven layout positions of the antennas and the inconsistent radiation patterns between the antennas, it is difficult for algorithms such as the MUSIC algorithm to estimate the direction of the incoming wave, and it is also difficult to perform amplitude-phase control. This embodiment introduces the time-reversal technology. On the one hand, it can reduce the process of incoming wave estimation. On the other hand, based on time reversal, the phase difference and amplitude ratio are obtained, and at least two target antennas perform beamforming with the phase difference and amplitude ratio, which can achieve energy point focusing, and based on channel reciprocity, the RF signals can be more effectively transmitted between the electronic device 10 and the network device 20, thereby improving the communication quality of the electronic device 10 and then enhancing the user's communication experience.

[0054] In one embodiment, at least two target antennas are determined based on the amplitude ratio. It can be understood that the target antennas determined based on the amplitude ratio transmit the RF signals according to the amplitude ratio when transmitting the RF signals.

[0055] Among them, the adjustment module 130 is configured to perform phase shift processing on the RF signals transmitted on the target RF path according to the phase difference, so that at least two target antennas transmit the RF signals with the phase difference.

[0056] The adjustment module 130 can be understood as a phase shift module with a phase shift processing function. The adjustment module 130 can be configured with different phase shift values, supporting phase adjustment of radio frequency signals transmitted on different target radio frequency paths with different phase shift values; it can also support phase adjustment of different phase shift values for the same target radio frequency path under different circumstances, such as different phase differences obtained based on reference signals of different network devices 20.

[0057] By performing phase shift processing on the radio frequency signals transmitted on each target radio frequency path according to the phase difference obtained by the adjustment module 130 through time reversal, it can enable at least two target antennas to transmit radio frequency signals with corresponding phase differences on the basis of the aforementioned amplitude ratio. It can be understood that at least two target antennas transmitting radio frequency signals with an amplitude ratio and a phase difference can include: in the case of transmit beamforming, the target antenna receives the radio frequency signal after phase shift adjustment processing and transmits the radio frequency signal with the corresponding amplitude ratio; in the case of receive beamforming, the target antenna receives the radio frequency signal with the corresponding amplitude ratio, and the radio frequency signal is then subjected to phase shift processing by the adjustment module 130, so that different target radio frequency paths transmit radio frequency signals with corresponding phase differences.

[0058] It can be understood that in other embodiments, if the amplitudes of the signals transmitted by each target antenna itself are the same, that is, the amplitude attenuation degrees of the signals transmitted between different antennas are the same, in order to enable at least two target antennas to perform beamforming with corresponding phase differences and amplitude ratios, the adjustment module 130 can adopt a module with both a phase shift processing function and an amplitude attenuation adjustment function. For example, the adjustment module 130 can be a combination of a phase shift module and an amplitude adjustment module 130, and the present application will not introduce them one by one.

[0059] In one embodiment, as Figure 4 shown, the adjustment module 130 includes a plurality of phase shift circuits 131. A phase shift circuit 131 is provided in any target radio frequency path between the radio frequency module 110 and at least two target antennas. The phase shift circuit 131 is used to perform phase shift processing on the radio frequency signal transmitted on the target radio frequency path.

[0060] Among them, each phase shift circuit 131 is arranged between the radio frequency module 110 and the target antenna, and can support phase shift processing of the radio frequency signal transmitted on the target radio frequency path where the target antenna is located. Exemplarily, in the case of transmit beamforming, each phase shift circuit 131 can perform phase shift processing on the radio frequency signal processed by the radio frequency module 110; in the case of receive beamforming, each phase shift circuit 131 can perform phase shift processing on the radio frequency signal received by the target antenna.

[0061] In this embodiment, by arranging a phase shifter circuit 131 on any target radio frequency path, each phase shifter circuit 131 can be adjusted specifically according to the phase requirements of the target radio frequency path where it is located, improving the effectiveness and efficiency of the phase adjustment of each target radio frequency path. At the same time, the flexibility and specificity of the overall phase adjustment of the adjustment module 130 can be improved.

[0062] In one embodiment, as Figure 5 shown (the processing module 120 is not shown in the figure), the radio frequency module 110 includes a plurality of transmitting circuits 111 and a plurality of receiving circuits 112 (only one transmitting circuit 111 and one receiving circuit 112 are shown in the figure). The plurality of transmitting circuits 111 and the plurality of receiving circuits 112 are respectively connected to the radio frequency transceiver. The transmitting circuit 111 is used for performing transmission processing on the radio frequency signal. For example, the transmitting circuit 111 may include a power amplifier (PA, Power Amplifier) and a filter (SAW, Surface Acoustic Wave) (the filter is SAW1 in the figure), and the transmission processing may be power amplification processing and filtering processing; the receiving circuit 112 is used for performing reception processing on the radio frequency signal. For example, the receiving circuit 112 may include a low noise amplifier (LNA, Low Noise Amplifier) and a filter (the filter is SAW2 in the figure), and the reception processing may be low noise amplification processing and filtering processing. The radio frequency transceiver is used for providing the radio frequency signal to be transmitted to the transmitting circuit 111, and is also used for receiving the radio frequency signal that has been received and processed by the receiving circuit 112.

[0063] In this embodiment, the electronic device 10 further includes: a first switch module 140. The first switch module 140 is respectively connected to the plurality of transmitting circuits 111, the plurality of receiving circuits 112, and the plurality of phase shifter circuits 131, and is used for switchably connecting each phase shifter circuit 131 to any one of the transmitting circuits 111 or any one of the receiving circuits 112.

[0064] Wherein, each phase shifter circuit 131 is switchably connected to the transmitting circuit 111 and can also be switchably connected to the receiving circuit 112. When switched to be connected to the transmitting circuit 111, the phase shifter circuit 131 can support phase shifting the radio frequency signal after being transmitted and processed by the radio frequency module 110 according to the phase difference; when switched to be connected to the receiving circuit 112, it can switchably support phase shifting the radio frequency signal to be received and processed by the radio frequency module 110 according to the phase difference.

[0065] By configuring the first switch module 140 to have a selective conduction function between different objects and configuring the phase shift circuit 131 to perform phase shift processing on the transmitted and received signals, on the one hand, the multiplexing of the phase shift circuit 131 can be achieved, reducing the number of phase shifters and lowering the cost; on the other hand, the transmitting circuit 111 and the receiving circuit 112 can be switched to conduct different target antennas, meeting the requirements of more different scenarios.

[0066] Exemplarily, the first switch module 140 can be a multi-pole multi-throw switch, and by controlling the switching state of the multi-pole multi-throw switch, the switching of the connection paths between multiple transmitting circuits 111, multiple receiving circuits 112 and any one phase shift circuit 131 can be realized.

[0067] In one embodiment, the electronic device 10 further includes a radio frequency transceiver, which is used to support the transmission of radio frequency signals to be transmitted to the radio frequency module 110, and is also used to support the reception of radio frequency signals received and processed by the radio frequency module 110; the adjustment module 130 includes multiple phase shift circuits 131, and a phase shift circuit 131 is provided on any target radio frequency path between the radio frequency transceiver and the radio frequency module 110, and the phase shift circuit 131 is used to perform phase shift processing on the radio frequency signals transmitted on the target radio frequency path.

[0068] Among them, each phase shift circuit 131 is arranged between the radio frequency module 110 and the radio frequency transceiver, and can support the phase shift processing of the radio frequency signals transmitted on the target radio frequency path where the target antenna is located. Exemplarily, in the case of transmitting beamforming, the phase shift circuit 131 can perform phase shift processing on the radio frequency signals before the radio frequency module 110 amplifies the power of the radio frequency signals to be transmitted, reducing the phase shift insertion loss during transmission while facilitating transmitting beamforming; in the case of receiving beamforming, the phase shift circuit 131 can perform phase shift processing on the radio frequency signals after the radio frequency module 110 performs low-noise amplification processing on the radio frequency signals, reducing the phase shift insertion loss during reception while facilitating receiving beamforming.

[0069] In this embodiment, by arranging the phase shift circuit 131 on any target radio frequency path and the phase shift circuit 131 is located between the radio frequency transceiver and the radio frequency module 110, on the one hand, the effectiveness and efficiency of phase adjustment of each target radio frequency path can be improved, and at the same time, the flexibility and pertinence of the overall phase adjustment of the adjustment module 130 can be improved; on the other hand, the phase shift insertion loss when each target radio frequency path transmits radio frequency signals can be effectively reduced, further improving the communication quality.

[0070] It can be understood that in the above embodiments, the target RF path can be only the transmitting path, and the phase shifter circuit 131 can be only arranged on the transmitting path, so that the electronic device 10 supports transmitting beamforming and improves the transmitting performance; the target RF path can also be only the receiving path, and the phase shifter circuit 131 can be only arranged on the receiving path, so that the electronic device 10 supports receiving beamforming and improves the receiving performance.

[0071] In one embodiment, as Figure 6 shown, the RF module 110 includes a plurality of transmitting circuits 111 and a plurality of receiving circuits 112. The transmitting circuit 111 and the receiving circuit 112 can refer to the relevant descriptions of the above embodiments and will not be elaborated here.

[0072] In this embodiment, the electronic device 10 further includes: a second switch module 150. The second switch module 150 is respectively connected to the plurality of transmitting circuits 111 and the plurality of receiving circuits 112, and is used to switchably conduct the transmitting circuit 111 to any antenna, and switchably conduct the receiving circuit 112 to any antenna, so that the transmitting circuit 111 and the receiving circuit 112 can be switchably conducted to different target antennas to meet the requirements of more different scenarios.

[0073] Wherein, when the electronic device 10 needs to support receiving beamforming, a phase shifter circuit 131 can be arranged between the RF transceiver and the receiving circuit 112, and the phase shifter circuit 131 between the RF transceiver and the receiving circuit 112 supports phase-shifting the RF signal received and processed by the receiving circuit 112 according to the phase difference; and / or, when the electronic device 10 needs to support transmitting beamforming, a phase shifter circuit 131 can be arranged between the RF transceiver and the transmitting circuit 111, and the phase shifter circuit 131 between the RF transceiver and the transmitting circuit 111 supports phase-shifting the RF signal to be transmitted by the transmitting circuit 111 according to the phase difference.

[0074] By arranging the phase shifter circuit 131 between the RF transceiver and the transmitting circuit 111 and / or the receiving circuit 112, the phase shift insertion loss can be reduced on the basis of supporting beamforming, and the communication quality between the electronic device 10 and the network device 20 can be further improved.

[0075] Exemplarily, the second switch module 150 can be a multi-pole multi-throw switch, so that by controlling the switching state of the multi-pole multi-throw switch, the switching of the connection paths between the plurality of transmitting circuits 111, the plurality of receiving circuits 112 and any antenna can be realized.

[0076] The above phase shifter circuit 131 can adopt a commercial phase shifter device or chip; it can also adopt a phase shifter circuit 131 composed of distributed or lumped elements (capacitors / inductors) and switch units.

[0077] In one embodiment, as Figure 7 shown, the phase shift circuit 131 includes: a high-pass phase shift unit 1311, a low-pass phase shift unit 1312, a first switch unit 1313, and a second switch unit 1314.

[0078] The high-pass phase shift unit 1311 is configured to pass the radio frequency signals in the high-frequency band and cause the passed radio frequency signals to have a phase lead. Thus, the vector rotation angle of the radio frequency signals transmitted on the target radio frequency channel where the high-pass phase shift unit 1311 is located is larger than that of other signals, and on the time axis, it reaches a specific point, such as a peak or a trough, earlier.

[0079] The low-pass phase shift unit 1312 is configured to pass the radio frequency signals in the low-frequency band and cause the passed radio frequency signals to have a phase lag. Thus, the vector rotation angle of the radio frequency signals transmitted on the target radio frequency channel where the low-pass phase shift unit 1312 is located is smaller than that of other signals, and on the time axis, it reaches a specific point, such as a peak or a trough, later.

[0080] The first switch unit 1313, the first end of the first switch unit 1313 is connected to a first object, and the two second ends of the first switch unit 1313 are respectively connected to the high-pass phase shift unit 1311 and the low-pass phase shift unit 1312. The first switch unit 1313 is configured to conductively connect the first object to any one of the high-pass phase shift unit 1311 and the low-pass phase shift unit 1312; the second switch unit 1314, the first end of the second switch unit 1314 is connected to a second object, and the two second ends of the second switch unit 1314 are respectively connected to the high-pass phase shift unit 1311 and the low-pass phase shift unit 1312. The second switch unit 1314 is configured to conductively connect the second object to any one of the high-pass phase shift unit 1311 and the low-pass phase shift unit 1312; wherein, the first object is the radio frequency module 110, and the second object is the antenna; or the first object is the radio frequency transceiver, and the second object is the radio frequency module 110.

[0081] Through the first switching unit 1313 and the second switching unit 1314, any one of the high-pass phase-shifting unit 1311 and the low-pass phase-shifting unit 1312 can be commonly selected to be turned on and connected to the first object and the second object respectively, so that the phase-shifting circuit 131 can switch different phase-shifting values to perform corresponding phase-shifting processing on the radio frequency signal on the target radio frequency path. It can be understood that the switching conditions of the first switching unit 1313 and the second switching unit 1314 on different target radio frequency paths may not be the same or may be the same. The corresponding phase-shifting values of the high-pass phase-shifting unit 1311 and the low-pass phase-shifting unit 1312 on different target radio frequency paths may also be the same or different. Therefore, by combining the first switching unit 1313, the second switching unit 1314, the high-pass phase-shifting unit 1311, and the low-pass phase-shifting unit 1312 on different target radio frequency paths, a phase difference required for the time-reversal signal can be made to exist in the radio frequency signals transmitted on different target radio frequency paths.

[0082] Therefore, by switching different phase-shifting units through the first switching unit 1313 and the second switching unit 1314 on different target radio frequency paths, the phase of the antenna transmission signal on different target radio frequency paths can be controlled to be advanced or lagged, so that the synthesized electromagnetic wave beam can be directed to a specific direction, improving the directivity and gain of signal transmission.

[0083] Exemplarily, the numbers of the above-mentioned high-pass phase-shifting unit 1311 and low-pass phase-shifting unit 1312 can be one or more respectively, and the specific numbers and phase-shifting values can be adjusted and set with reference to actual requirements.

[0084] Exemplarily, the above-mentioned high-pass phase-shifting unit 1311 and low-pass phase-shifting unit 1312 can respectively include a capacitor and an inductor. For specific optional examples and their corresponding connection relationships, please refer to Figure 7 , and the first switching unit 1313 and the second switching unit 1314 can respectively include single-pole double-throw switches.

[0085] In one embodiment, as Figure 8 shown, the processing module 120 includes: a radio frequency transceiver 121 and a processor 122.

[0086] Among them, the radio frequency transceiver 121 is used to support the transmission of the radio frequency signal to be transmitted to the radio frequency module 110, support the reception of the radio frequency signal and the reference signal received and processed by the radio frequency module 110, and is also used to obtain the reception information of the reference signal. Therefore, through the radio frequency transceiver 121, the processing module 120 can analyze and obtain the amplitude and phase of the reference signal.

[0087] Among them, the processor 122 is connected to the radio frequency transceiver 121 and is used to perform time reversal based on the received information to obtain the phase difference and amplitude ratio, and output an instruction to the radio frequency transceiver 121 based on the phase difference and amplitude ratio, so that the radio frequency transceiver 121 controls the adjustment module 130 to perform phase shift processing on the radio frequency signal transmitted on the target radio frequency path, so as to finally make each target antenna reach a more accurate beam pointing. The angle of this beam pointing has the maximum gain, improving the communication quality between the electronic device 10 and the network device 20, thereby improving the user experience.

[0088] Exemplarily, the processor 122 may be a baseband processor (Modem). On the one hand, the baseband processor can carry relevant service information on the baseband signal and modulate the baseband signal to obtain the radio frequency signal to be transmitted and transmit it to the radio frequency transceiver 121. It can also modulate the radio frequency signal received by the radio frequency transceiver 121 and convert it into a baseband signal carrying relevant service information. On the other hand, the baseband processor in this embodiment can also perform time reversal calculation to obtain the phase difference and amplitude ratio required for the time reversal signal, and output an instruction to the radio frequency transceiver 121 based on this, so that the radio frequency transceiver 121 controls the adjustment module 130 to perform phase shift processing on the radio frequency signal transmitted on the target radio frequency path.

[0089] Exemplarily, the processor 122 and the radio frequency transceiver 121 can be respectively configured with one of the MIPI (Mobile Industry Processor Interface) interface and the GPIO (General Purpose Input Output) interface. The processor 122 can transmit an instruction to the radio frequency transceiver 121 through the MIPI interface or the GPIO interface. The radio frequency transceiver 121 can send a switch switching control signal to the above-mentioned switch module, switch unit, etc. through the MIPI interface or the GPIO interface to control the conduction state between the target antenna and the radio frequency module 110 and control the phase shift processing state of the phase shift circuit 131.

[0090] It can be understood that in the above embodiment, the adjustment module 130 is mainly taken as an example of the phase shift module for illustration. The phase shift module can be understood as being set on the radio frequency side at the front end of the electronic device 10 to realize the adjustment of the phase of the front-end radio frequency signal. In other embodiments, the adjustment module 130 can adopt other circuit devices.

[0091] In one embodiment, the adjustment module 130 is respectively connected to the feeding points of multiple antennas and the RF module 110, and is configured to perform matching processing on the RF signals transmitted on the target RF path according to the configured matching parameters, so as to adjust the phase of the RF signals, such that at least two target antennas also transmit RF signals with a phase difference; wherein, the matching parameters are determined based on the phase difference, and at least two target antennas are determined based on the amplitude ratio.

[0092] The adjustment module 130 can be understood as an antenna matching module with the function of antenna matching adjustment. The adjustment module 130 can be configured with different matching parameters, supporting the adjustment of different matching parameters for the RF signals transmitted on different target RF paths to achieve the adjustment of different phase differences; it can also support the adjustment of different matching parameters for the same target RF path under different conditions, for example, different phase differences obtained based on the reference signals of different network devices 20. The adjustment module 130 can be understood as being disposed on the antenna side in the electronic device 10 to achieve the adjustment of the phase of the antenna feeding signal. The matching parameters of the adjustment module 130 are determined based on the phase difference obtained by the processing module 120, and at least two target antennas are determined based on the amplitude ratio obtained by the processing module 120.

[0093] By performing matching adjustment on the RF signals at the feeding points of the target antennas on each target RF path according to the phase difference obtained by the adjustment module 130 through time reversal, it can be made such that at least two target antennas also transmit RF signals with the corresponding phase difference on the basis of the foregoing amplitude ratio.

[0094] Exemplarily, the adjustment module 130 can include a switch unit and multiple matching units with different matching parameters. The processing module 120 can control the switching state of the switch unit, and then switch different matching units, such that the adjustment module 130 is configured with different matching parameters, and performs matching adjustment on the RF signals at the antenna feeding points based on the configured matching parameters. The matching units can be devices such as capacitors and inductors, and specific details of which are not introduced one by one in this embodiment.

[0095] In one embodiment, as Figure 9 shown, the RF module 110 includes a multi-channel transceiver circuit, and the transceiver circuit includes a transmitting circuit (only one transmitting circuit is shown in the figure) and a receiving circuit; the processing module 120 includes: an RF transceiver 121, a processor 122, and a control circuit 123.

[0096] The radio frequency transceiver 121 is connected to the radio frequency module 110, and is used to provide a radio frequency signal to be transmitted to the transceiver circuit, receive the radio frequency signal and the reference signal processed by the transceiver circuit, and obtain the reception information of the reference signal; the processor 122 is connected to the radio frequency transceiver 121, and is used to perform time reversal based on the reception information to obtain a phase difference and an amplitude ratio. The descriptions of the radio frequency transceiver 121 and the processor 122 can refer to the above embodiments and will not be elaborated here.

[0097] In this embodiment, the control circuit 123 is connected to the processor 122, and is used to obtain the transmission power information of multiple transceiver circuits, determine the reflection coefficient of the antenna connected to the multiple transceiver circuits based on the power information, determine at least two target antennas based on the amplitude ratio, and configure the matching parameters of the adjustment module 130 based on the reflection coefficient and the phase difference.

[0098] Thus, through the cooperation of the control circuit 123, the processor 122, and the radio frequency transceiver 121, the configuration of the matching parameters of the adjustment module 130 is realized.

[0099] In one of the embodiments, as Figure 9 , Figure 10 shown, the transceiver circuit is provided with a coupler (such as CPL1... CPLn in the figure), and the control circuit 123 includes: a radio frequency control chip and a system-on-chip.

[0100] The radio frequency control chip is used to obtain the power information based on the coupled signal output by the coupler, and output the reflection coefficient based on the coupling information; the system-on-chip (SOC, System-on-a-Chip) is respectively connected to the radio frequency control chip and the processor 122, and is used to output an adjustment instruction to the radio frequency control chip according to the phase difference, the amplitude ratio, and the reflection coefficient, so that the radio frequency control chip controls the adjustment module 130 to adjust the matching parameters of at least two target antennas.

[0101] Among them, the coupler can perform coupling processing on the radio frequency signal transmitted on the transceiver circuit, and output a coupled signal to the radio frequency control chip, so that the radio frequency control chip obtains the power information of the radio frequency signal transmitted by the transceiver circuit based on the coupled signal. The power information can include the forward coupled power and the reverse reflected power, and then obtain the reflection coefficient of the antenna load based on the power information. The system-on-chip can output corresponding adjustment instructions based on the received phase difference, amplitude ratio, and reflection coefficient, so that the radio frequency control chip controls the on-off state of the switch unit inside the adjustment module 130 to realize the configuration of the matching parameters of the adjustment module 130. As Figure 11 shown, the phase movement of each target antenna on the Smith chart is realized.

[0102] Exemplarily, the radio frequency control chip may include a microcontroller unit (MCU), an analog-to-digital converter (ADC), and a detection circuit. The detection circuit detects the coupled signal output by the coupler. The ADC can perform analog-to-digital conversion processing on the coupled signal and then output it to the MCU. The MCU feeds back to the SOC and controls the adjustment module 130 based on the adjustment instruction output by the SOC. Exemplarily, the coupler may be a directional coupler inside the PA in the transceiver circuit or an externally added directional coupler. This embodiment does not limit this.

[0103] Exemplarily, in other embodiments, the radio frequency transceiver 121 may also be configured to be connected to the coupler to obtain the power information of the transceiver circuit through the coupled signal output by the coupler, and obtain the emission coefficient based on the power information; the processor 122 may also be configured to output an adjustment instruction to the radio frequency transceiver 121 based on the phase difference, amplitude ratio, and reflection coefficient, so that the radio frequency transceiver 121 controls the adjustment module 130 to adjust the matching parameters of at least two target antennas.

[0104] Based on the same inventive concept, the embodiments of the present application also provide a beamforming method and a beamforming device, which are applied to an electronic device. The electronic device includes multiple antennas, a radio frequency module, and an adjustment module. The radio frequency module is connected to the multiple antennas. The multiple antennas, the radio frequency module, and the adjustment module refer to the above embodiments. The implementation solutions provided by the beamforming method and the beamforming device to solve the problems are similar to the implementation solutions described in the above electronic device. Therefore, the specific limitations in the embodiments of the beamforming method and the beamforming device provided below can refer to the limitations on the electronic device in the above text, and will not be repeated here.

[0105] In one of the embodiments, as Figure 12 shown, the beamforming method includes: step 102 - step 104.

[0106] Step 102, when the radio frequency module receives the reference signal transmitted by the network device through multiple antennas, based on the reception information of the reference signal received by the multiple antennas, perform time reversal to obtain the phase difference and amplitude ratio of the time reversal signals transmitted between the multiple antennas;

[0107] Step 104, based on the phase difference and amplitude ratio, control the adjustment module to adjust the parameters of the radio frequency signal transmitted on the target radio frequency path. The target radio frequency path is the path between the radio frequency module and at least two target antennas among the multiple antennas, so that at least two target antennas perform beamforming with the phase difference and amplitude ratio.

[0108] Among them, steps 102 and 104 can be executed by the processing module in the above embodiments. For relevant introductions, reference can be made to the above embodiments and will not be elaborated here.

[0109] The beamforming method provided in this embodiment introduces time reversal technology. On the one hand, it can reduce the process of incident wave estimation. On the other hand, based on time reversal, the phase difference and amplitude ratio are obtained, and the adjustment module is controlled to adjust the parameters of the radio frequency signal transmitted on the target radio frequency path, so that at least two target antennas perform beamforming with the phase difference and amplitude ratio, which can achieve energy point focusing, and based on channel reciprocity, the radio frequency signal can be more effectively transmitted between the electronic device and the network device, thereby improving the communication quality of the electronic device and then enhancing the user's communication experience.

[0110] In one of the embodiments, as Figure 13 shown, the beamforming device includes: an acquisition module 202 and a control module 204.

[0111] The acquisition module 202 is configured to perform time reversal based on the reception information of the reference signals received by multiple antennas when the radio frequency module receives the reference signals transmitted by the network device through multiple antennas, and obtain the phase difference and amplitude ratio of the time reversal signals transmitted between the multiple antennas.

[0112] The control module 204 is configured to control the adjustment module to adjust the parameters of the radio frequency signal transmitted on the target radio frequency path based on the phase difference and amplitude ratio. The target radio frequency path is the path between the radio frequency module and at least two target antennas among the multiple antennas, so that at least two target antennas perform beamforming with the phase difference and amplitude ratio.

[0113] Among them, the acquisition module 202 and the control module 204 can correspond to the processing module in the above embodiments. For relevant introductions, reference can be made to the above embodiments and will not be elaborated here.

[0114] The beamforming device provided in this embodiment introduces time reversal technology. On the one hand, it can reduce the process of incident wave estimation. On the other hand, based on time reversal, the phase difference and amplitude ratio are obtained, and the adjustment module is controlled to adjust the parameters of the radio frequency signal transmitted on the target radio frequency path, so that at least two target antennas perform beamforming with the phase difference and amplitude ratio, which can achieve energy point focusing, and based on channel reciprocity, the radio frequency signal can be more effectively transmitted between the electronic device and the network device, thereby improving the communication quality of the electronic device and then enhancing the user's communication experience.

[0115] The following further explains the above embodiments with specific optional embodiments:

[0116] Taking the network device as a base station and the electronic device as a mobile phone, and the mobile phone includes four antennas (such as Figure 14As shown, they are ANT1, ANT2, ANT3, and ANT4 respectively. Taking the adjustment module including multiple phase shifter circuits as an example, where ANT1 is located on the left side of the back view of the mobile phone, ANT2 is located on the right side of the back view of the mobile phone, ANT3 is located in the upper left corner of the back view of the mobile phone, and ANT4 is located in the upper right corner of the back view of the mobile phone. The radiation patterns of the four antennas are correspondingly as Figures 15 - 18 shown.

[0117] In order to obtain a beam in a specific direction:

[0118] The first step: The processing module obtains the reception information of each reception path by analyzing the reference signal transmitted by the base station received, and the reception information includes amplitude and phase n represents the label of the antenna.

[0119] The second step: Based on the reception information, perform time reversal to obtain the time reversal signals of each antenna

[0120] The third step: Based on the time reversal signals, obtain the phase difference and amplitude ratio required for the target antenna to transmit signals. For example, the phase difference required between ANT1 and ANT2 is The power ratio required between ANT1 and ANT2 is (A1 / A2).

[0121] The fourth step: Control each phase shifter circuit to adjust the phase of the radio frequency signal transmitted on the target radio frequency path, so that at least two target antennas among the four antennas perform beamforming with the phase difference and amplitude ratio.

[0122] For example, when the antenna is excited by a plane wave signal in the back view direction (theta = 155°, phi = 90°), the amplitudes and phases obtained for each antenna are ANT1(1.1, 286°), ANT2(0.33, 33°), ANT3(0.37, 75°), ANT4(1.37, 167°) respectively. After time reversal, the reversed signals obtained for each antenna are: ANT1(1.1, -286°), ANT2(0.33, -33°), ANT3(0.37, -75°), ANT4(1.37, -167°).

[0123] Based on the phase difference and amplitude ratio required by the foregoing time reversal signals, select ANT1 - ANT4 as the target antennas, and respectively excite them through the phase shifter circuits with (1.1, -286°), (0.33, -33°), (0.37, -75°), (1.37, -167°) to form a combined beam as Figure 19 shown, and the beam deflects 65° to the left; or, select ANT1 and ANT4 as the target antennas, and respectively excite them through the phase shifter circuits with (1, -286°), (1, -167°) to form a combined beam as Figure 20 shown.

[0124] For example, when the antenna is excited by a plane wave signal in the back view direction (theta = 90°, phi = 90°), the amplitudes and phases of each antenna are obtained as ANT1(0.84, 195°), ANT2(0.54, 155°), ANT3(0.63, 0.9°), ANT4(1.06, 248°) respectively. After time reversal, the inverted signals of each antenna are obtained: ANT1(0.84, -195°), ANT2(0.54, -155°), ANT3(0.63, -0.9°), ANT4(1.06, -248°).

[0125] Based on the phase differences and amplitude ratios required for the aforementioned time-reversed signals, ANT1 - ANT4 are selected as the target antennas and are respectively excited by the phase shifter circuits with (0.84, -195°), (0.54, -155°), (0.63, -0.9°), (1.06, -248°) to form a synthetic beam as shown in Figure 21 the figure, and the beam is perpendicular to the direction of the rear cover; alternatively, ANT1 and ANT4 are selected as the target antennas and are respectively excited by the phase shifter circuits with (1, -195°), (1, -248°) to form a synthetic beam as shown in Figure 22 the figure.

[0126] It can be understood that for the different target antennas selected above, beam synthesis can be achieved as long as the amplitude ratios and phase differences between different antennas are close to or equal to the phase differences and amplitude ratios between the time-reversed signals, without the need for the specific amplitudes and phases corresponding to the time-reversed signals to be the same.

[0127] The embodiment of the present application also provides a computer device, including a memory and a processor. The memory stores a computer program, and when the processor executes the computer program, the steps of the beam synthesis method as described above are implemented, which can improve the communication quality between the electronic device and the network device and enhance the user experience.

[0128] The embodiment of the present application also provides a computer-readable storage medium. One or more non-volatile computer-readable storage media containing computer-executable instructions, when the computer-executable instructions are executed by one or more processors, cause the processors to execute the steps of the beam synthesis method.

[0129] The present application also provides a computer program product, including a computer program, and when the computer program is executed by a processor, the steps of the beam synthesis method in the above embodiment are implemented.

[0130] Any reference to memory, storage, database, or other media used in this application may include non-volatile and / or volatile memory. Non-volatile memory may include read-only memory (ROM), magnetic tape, floppy disk, flash memory, optical memory, high-density embedded non-volatile memory, resistive random access memory (ReRAM), magnetoresistive random access memory (MRAM), ferroelectric random access memory (FRAM), phase change memory (PCM), graphene memory, etc. Volatile memory may include random access memory (RAM) or external cache memory, etc. By way of illustration and not limitation, RAM can be in various forms, such as static random access memory (SRAM) or dynamic random access memory (DRAM), etc.

[0131] The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.
