[0019] Hereinafter, embodiments of the present disclosure will be described with reference to the accompanying drawings. However, it should be understood that these descriptions are exemplary only and are not intended to limit the scope of the present disclosure. In the following detailed description, for ease of explanation, many specific details are set forth to provide a comprehensive understanding of the embodiments of the present disclosure. However, it is apparent that one or more embodiments may also be implemented without these specific details. In addition, in the following description, descriptions of known structures and technologies are omitted to avoid unnecessary confusion of the concepts of the present disclosure.

[0020] The terms used herein are only for describing specific embodiments and are not intended to limit the present disclosure. The terms "comprise", "include", etc. used herein indicate the existence of the features, steps, operations and / or components, but do not exclude the existence or addition of one or more other features, steps, operations or components.

[0021] All terms (including technical and scientific terms) used herein have the meanings commonly understood by those skilled in the art unless otherwise defined. It should be noted that the terms used herein should be interpreted as having a meaning consistent with the context of this specification and should not be interpreted in an idealized or overly rigid manner.

[0022] When using expressions such as "at least one of A, B, and C, etc.", they should generally be interpreted according to the meaning of the expression commonly understood by those skilled in the art (for example, "a system having at least one of A, B, and C" should include but is not limited to a system having A alone, B alone, C alone, A and B, A and C, B and C, and / or A, B, C, etc.).

[0023] In the embodiments of the present disclosure, the collection, updating, analysis, processing, use, transmission, provision, disclosure, storage, etc. of the data involved (for example, including but not limited to user personal information) are in compliance with the provisions of relevant laws and regulations, are used for legitimate purposes, and do not violate public order and good morals. In particular, necessary measures are taken for user personal information to prevent illegal access to user personal information data and maintain the security of user personal information, network security, and national security.

[0024] In the embodiments of the present disclosure, the user's authorization or consent is obtained before obtaining or collecting the user's personal information.

[0025] Some electronic devices use a 2x2 MIMO solution or a 4x4 MIMO solution, wherein the 2x2 MIMO solution means that a base station sends two signals, and the electronic device receives the two signals through two antennas. Similarly, the 4x4 MIMO solution means that a base station sends four signals, and the electronic device receives the four signals through four antennas.

[0026] In practical applications, due to the size limitations of electronic devices and the small size of antennas corresponding to high frequencies, electronic devices used to transmit signals in the medium frequency band (e.g., 1.7GHz-4.2GHz) can be equipped with 4 antennas to implement the 4x4MIMO solution. However, for electronic devices that transmit signals in the low frequency band (below 1GHz), since the size of the electronic devices is small and the size of the low frequency antenna is large, these electronic devices are usually equipped with 2 antennas to implement the 2x2MIMO solution. It is understandable that a small number of antennas will cause the problem of low throughput.

[0027] The present disclosure aims to provide an electronic device, which can use a smaller number of first antennas to transmit more signals in a first transmission scenario with a stronger transmission signal, thereby achieving the signal transmission effect of a larger number of antennas; at the same time, the electronic device can also ensure signal transmission performance in a second transmission scenario with a weaker transmission signal, thereby achieving an improvement in throughput. In some embodiments of the present disclosure, the electronic device can use three antennas to implement a 4x4 MIMO function under strong signals, and implement diversity reception under weak signals, and use three antennas to achieve an improvement in throughput.

[0028] The technical solution provided by the present disclosure will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] Figure 1 A schematic structural diagram of an electronic device according to an embodiment of the present disclosure is schematically shown.

[0030] In this embodiment, the electronic device 100 includes a signal transceiver unit 110 , a first antenna 120 and a switching unit 130 .

[0031] For example, the signal transceiver unit 110 may be a transceiver for implementing bidirectional transmission of signals. This embodiment does not limit the structure of the signal transceiver unit 110 .

[0032] For example, the number of the first antennas 120 may be one or more than two, and this embodiment does not limit the number of the first antennas 120 .

[0033] For example, there is a first signal transmission path between the first antenna 120 and the signal transceiver unit 110, and the first antenna 120 corresponds to the first signal transmission path one by one. The first signal transmission path enables the corresponding first antenna 120 to maintain electrical connection with the signal transceiver unit 110 and transmit signals. In addition, there is a second signal transmission path that can be turned on and off between the first antenna 120 and the signal transceiver unit 110, and the first antenna 120 corresponds to the second signal transmission path one by one. The second signal transmission path is switched by the switching unit 130 to achieve the state change of on and off.

[0034] For example, the number of the switching units 130 may be one or more than two, and this embodiment does not limit the number of the switching units 130, and the switching units 130 correspond one to one with the first antenna 120. The switching unit 130 may be disposed between the first antenna 120 and the signal transceiver unit 110, for example, the switching unit 130 is disposed in the second signal transmission path.

[0035] During operation, the electronic device 100 may be applicable to the first transmission scenario and the second transmission scenario, wherein the strength of the transmission signal in the first transmission scenario is greater than the strength of the transmission signal in the second transmission scenario. For example, the strength of the transmission signal in the first transmission scenario is greater than or equal to -80dBm, while in the second transmission scenario, the strength of the transmission signal is less than or equal to -90dBm. This embodiment does not limit the strength of the transmission signal in the first transmission scenario and the second transmission scenario.

[0036] In the first transmission scenario, the switching unit 130 turns on the second signal transmission path, so that the second signal transmission path and the first signal transmission path transmit signals simultaneously. Compared with the method of transmitting signals only through the first signal transmission path, the second signal transmission path can increase the number of paths used to transmit signals, thereby increasing the amount of signals transmitted per unit time, and further increasing the signal transmission rate.

[0037] In the second transmission scenario, since the first signal transmission path and the second signal transmission path are in parallel, turning on the second signal transmission path will cause some path loss in the first signal transmission path. The switching unit 130 disconnects the second signal transmission path, thereby reducing the path loss of the first signal transmission path.

[0038] According to the technical solution provided by the embodiment of the present disclosure, the electronic device 100 may be a terminal device such as a mobile phone or a computer. In the first transmission scenario where the transmission signal is strong, the electronic device 100 may use a smaller number of first antennas 120 to transmit more signals, thereby achieving the signal transmission effect of a larger number of antennas. At the same time, in the second transmission scenario where the transmission signal is weak, the signal transmission performance of the first signal transmission path may also be guaranteed.

[0039] Figure 2 A schematic structural diagram of an electronic device according to another embodiment of the present disclosure is schematically shown.

[0040] In this embodiment, the electronic device 200 includes a signal transceiver unit 210, a first antenna 220, a switching unit 230 and a second antenna 240, wherein the signal transceiver unit 210, the first antenna 220, and the switching unit 230 can be referred to above and will not be repeated in this embodiment.

[0041] For example, the number of the second antennas 240 may be one or more than two. For example, the second antennas 240 include a first second antenna 241 and a second second antenna 242 . The embodiment does not limit the number of the second antennas 240 .

[0042] For example, there is a third signal transmission path between the second antenna 240 and the signal transceiver unit 210, and the second antenna 240 corresponds to the third signal transmission path one by one. The third signal transmission path enables the corresponding second antenna 240 to maintain electrical connection with the signal transceiver unit 210 and transmit signals.

[0043] In the first transmission scenario, the information carried by the multiple signals received by the first signal transmission path, the second signal transmission path, and the third signal transmission path is different from each other. For example, taking the electronic device 200 including 1 first signal transmission path, 1 second signal transmission path, and 2 third signal transmission paths as an example, the electronic device 200 can transmit 4 signals at the same time, and the information carried by the 4 signals is different from each other. In this way, based on the demodulation of the received 4-way signal to different information, the demodulated 4-way information can be merged into an information set. In this way, compared with the scheme of receiving one signal through only one signal transmission path, the information set demodulated by the above 4-way signal has more information, thereby achieving the effect of transmitting more signal volume per unit time, thereby improving the signal transmission rate.

[0044] In the second transmission scenario, the information carried by the multi-channel signals received by the first signal transmission path and at least one third signal transmission path is the same as each other. It can be understood that the strength of the signal affects the coding rate of the signal transmission, and a weak signal will cause the demodulated data to be abnormal. For example, taking the electronic device 200 including 1 first signal transmission path and 2 third signal transmission paths as an example, the electronic device 200 can transmit 3 signals at the same time, and the 3 signals are the same as each other. The 3 signals can be demodulated and then the demodulated information can be merged and processed. Compared with the solution of receiving one signal through only one signal transmission path, the information demodulated by the above 3 signals is more comprehensive, and the diversity reception of the signal is realized, thereby improving the signal quality.

[0045] It should be noted that in practical applications, sometimes there are some requirements for the number of signal transmission paths. For example, sometimes it is necessary to transmit three signals under weak signals. If the antennas in the electronic device 200 all use the first antenna 220 and the second antenna 240 is not set, two first antennas 220 can be arranged at this time, and two first signal transmission paths and one second signal transmission path can be used under weak signals to achieve the three-way signal transmission effect, but the second signal transmission path will cause the parallel first signal transmission path to generate path loss, thereby reducing the signal transmission effect. In this embodiment, the electronic device 200 also includes the second antenna 240, and the third signal transmission path between the second antenna 240 and the signal transceiver unit 210 remains in a conductive state, so that when three-way signal transmission is required, the three-way signal transmission effect can be achieved through one first signal transmission path and two third signal transmission paths, thereby reducing unnecessary path loss.

[0046] According to another embodiment of the present disclosure, the electronic device 200 includes a signal transceiver unit 210, a first antenna 220 and a switching unit 230, and there are a first signal transmission path and a second signal transmission path between the first antenna 220 and the signal transceiver unit 210, and the first signal transmission path and the second signal transmission path are both used to transmit signals with a frequency band less than or equal to 1 GHz.

[0047] According to another embodiment of the present disclosure, the electronic device 200 further includes a second antenna 240. A third signal transmission path exists between the second antenna 240 and the signal transceiver unit 210. The third signal transmission path can also be used to transmit signals with a frequency band less than or equal to 1 GHz.

[0048] It should be noted that, due to the size limitation of the electronic device 200 and the characteristic that the antenna size is small corresponding to the high frequency, the number of antennas that can be installed in the electronic device 200 for transmitting low-frequency signals is limited. For example, usually only two antennas can be designed for low frequency. The electronic device 200 provided in this embodiment can use a smaller number of antennas to achieve the signal transmission effect of a larger number of antennas, thereby reducing the space occupied by the antenna on the basis of meeting the signal transmission requirements and meeting the size design requirements of the electronic device 200.

[0049] like Figure 2 As shown, according to another embodiment of the present disclosure, the electronic device 200 includes a signal transceiver unit 210, a first antenna 220, a switching unit 230 and two second antennas 240, and the two second antennas 240 include a first second antenna 241 and a second second antenna 242. It can be seen that in this embodiment, the electronic device 200 includes a first signal transmission path, a second signal transmission path and two third signal transmission paths, and the electronic device 200 can use three antennas to achieve the effect of transmitting four signals in the first transmission scenario, and transmit three signals in the second transmission scenario to achieve a diversity reception effect.

[0050] like Figure 2 As shown, according to another embodiment of the present disclosure, the electronic device 200 includes a signal transceiver unit 210, a first antenna 220, a switching unit 230 and two second antennas 240, the two second antennas 240 include a first second antenna 241 and a second second antenna 242, wherein the first antenna 220 is used to receive signals, the first second antenna 241 is used to receive and send signals, and the second second antenna 242 is used to receive signals.

[0051] In this embodiment, the first second antenna 241 can be used as a signal transmitting antenna, while the second second antenna 242 and the first antenna 220 are used as signal receiving antennas. In practical applications, in order to reduce costs, the performance of the receiving antenna is weaker than that of the transmitting antenna. For example, the performance of the first antenna 220 and the second second antenna 242 in this embodiment are both weaker than that of the first second antenna 241. At the same time, in this embodiment, the first second antenna 241 and the signal transceiver unit 210 are electrically connected only through a third signal transmission path, and no other signal transmission paths that can be switched on and off are provided, so as to avoid other signal transmission paths causing path loss of the third signal transmission path of the first second antenna 241, thereby ensuring the performance of the first second antenna 241 that can transmit signals on the basis of reducing costs.

[0052] Figure 3 A schematic structural diagram of an electronic device according to another embodiment of the present disclosure is schematically shown.

[0053] In this embodiment, the electronic device 300 includes a signal transceiver unit 310 , a first antenna 320 , a switch unit 330 , and two second antennas 340 . The two second antennas 340 include a first second antenna 341 and a second second antenna 342 .

[0054] The first antenna 320 and the signal transceiver unit 310 are connected through a first signal transmission path, and a first filter 351 can be set on the first signal transmission path to realize a signal filtering function. At the same time, the first antenna 320 and the signal transceiver unit 310 are also connected through a second signal transmission path, and the second signal transmission path is switched by the switching unit 330 to realize the state change of on and off, and a second filter 352 can be set on the second signal transmission path to realize a signal filtering function.

[0055] The first second antenna 341 and the signal transceiver unit 310 are connected via a third signal transmission path, and a duplexer 360 can be set on the third signal transmission path to realize signal transmission and reception. In addition, a power amplifier 370 can be set between the duplexer 360 and the signal transceiver unit 310 to achieve a signal amplification effect.

[0056] The second second antenna 342 and the signal transceiver unit 310 are connected via another third signal transmission path, and a third filter 353 can be provided on the third signal transmission path to implement a signal filtering function.

[0057] In the first transmission scenario (for example, the signal strength is greater than or equal to -80dBm), the second signal transmission path is turned on, so that the second signal transmission path and the first signal transmission path simultaneously transmit the signal received by the first antenna 320. Although the path loss of the first signal transmission path will increase (for example, increase by 3dB), the three antennas can transmit four signals at this time, and the information carried by the four signals is different from each other. After testing, the modulation coding value of MCS=19 (64QAM) can be achieved. When a bandwidth of 10MHz is allocated for signal transmission in the low frequency band, the throughput of this example is 120Mbps, which is 1 times higher than the actual throughput of 60Mbps corresponding to the 2x2MIMO solution, and 20% higher than the maximum theoretical throughput of 100Mbps of the 2x2MIMO solution.

[0058] In the second transmission scenario (for example, the signal strength is less than or equal to -90dBm), the second signal transmission path is disconnected, and three signals can be transmitted at this time, and the information carried by the three signals is the same. Assuming that the receiving sensitivity of the first antenna 320 and the two second antennas 340 is -90dBm respectively, after testing, the overall receiving strength of the three antennas is -85.2dBm, and only the receiving strength of the two second antennas 340 is -87dBm, and the receiving strength is improved by 1.8dB.

[0059] According to another embodiment of the present disclosure, the electronic device further includes a matching unit, the matching unit may include at least one of a capacitor and an inductor, and the first end of the matching unit is electrically connected to the first signal transmission path. In addition, the switching unit includes: an input end, a first output end, and a second output end, wherein the input end can be selectively connected to the first output end or the second output end, and the switching unit may be, for example, a single-pole double-throw switch.

[0060] The input end of the switching unit is used to input the transmission signal received by the first antenna. In the first transmission scenario, the input end is connected to the first output end, and the input end is disconnected from the second output end. The transmission information received by the first antenna is input to the input end, and then output to the signal transceiver unit through the first output end and the second signal transmission path.

[0061] In the second transmission scenario, the input end is disconnected from the first output end, and connected to the second output end, and the second output end is electrically connected to the second end of the matching unit, and the matching unit is used to achieve impedance matching in the second transmission scenario.

[0062] It should be noted that, in this embodiment, the switching unit includes an input end, a first output end, and a second output end, and the second output end is connected to the matching unit to achieve impedance matching in the second transmission scenario. In other embodiments, the matching unit may include an input end and an output end, and the matching unit may use a single-pole single-throw switch, for example. In this case, the input end of the matching unit is connected to the output end to enable the second signal transmission path to be turned on, and the input end is disconnected from the output end to enable the second signal transmission path to be suspended.

[0063] According to another embodiment of the present disclosure, in an actual working process, in response to the intensity of the transmission signal increasing to a first intensity, the switching unit conducts the input end and the first output end. In response to the intensity of the transmission signal decreasing to a second intensity, the switching unit conducts the input end and the second output end. The first intensity is, for example, the minimum signal transmission intensity in the first transmission scenario, and the first intensity is, for example, -80dBm. The second intensity is, for example, the maximum signal transmission intensity in the second transmission scenario, and the second intensity is, for example, -90dBm. It can be seen that the first intensity is greater than the second intensity.

[0064] Take the first intensity as -80dBm and the second intensity as -90dBm as an example. In the process of gradually decreasing the intensity of the transmission signal, when the intensity of the transmission signal is greater than -80dBm, the input end is connected to the first output end, and the input end is disconnected from the second output end. When the intensity of the transmission signal gradually decreases and decreases from -80dBm to -90dBm, the connection status of the input end, the first output end, and the second output end remains unchanged. When the intensity of the transmission signal continues to decrease until it is less than -90dBm, the input end is disconnected from the first output end, and the input end is connected to the second output end.

[0065] Take the first intensity as -80dBm and the second intensity as -90dBm as an example. In the process of gradually increasing the intensity of the transmission signal, when the intensity of the transmission signal is less than -90dBm, the input end is disconnected from the first output end, and the input end is connected to the second output end. When the intensity of the transmission signal gradually increases and increases from -90dBm to -80dBm, the connection status of the input end, the first output end, and the second output end remains unchanged. When the intensity of the transmission signal continues to increase until it is greater than -80dBm, the input end is connected to the first output end, and the input end is disconnected from the second output end.

[0066] It can be seen that in this embodiment, when the strength of the transmission information is between -90dBm and -80dBm, the connection status of the input end, the first output end, and the second output end remains unchanged. This can avoid frequent operation of the switching unit caused by changes in the transmission signal strength, which is more conducive to the stability of signal transmission.

[0067] Figure 4 A schematic flowchart of an antenna control method of an electronic device according to an embodiment of the present disclosure is schematically shown.

[0068] In this embodiment, the structure of the electronic device can refer to the above. For example, the electronic device includes: a signal transceiver unit, at least one first antenna and at least one switching unit. The first antenna is electrically connected to the signal transceiver unit through a first signal transmission path, and the switching unit corresponds to the first antenna one by one.

[0069] In this embodiment, the electronic device can be applicable to the first transmission scenario and the second transmission scenario, wherein the strength of the transmission signal in the first transmission scenario is greater than the strength of the transmission signal in the second transmission scenario. The antenna control method 400 of the electronic device includes operations S410 to S420.

[0070] In operation S410, in response to determining that the strength of the transmission signal meets the first transmission scenario, the control switching unit turns on the second signal transmission path between the corresponding first antenna and the signal transceiver unit, performs signal transmission simultaneously with the first signal transmission path, and increases the signal transmission rate through the second signal transmission path.

[0071] In operation S420, in response to determining that the strength of the transmission signal satisfies the second transmission scenario, the switching unit is controlled to disconnect the second signal transmission path to reduce the path loss of the first signal transmission path.

[0072] In this embodiment, in the first transmission scenario where the transmission signal is strong, the electronic device can use a smaller number of first antennas to transmit more signals, thereby achieving the signal transmission effect of a larger number of antennas. At the same time, in the second transmission scenario where the transmission signal is weak, the signal transmission performance of the first signal transmission path can also be guaranteed.

[0073] According to another embodiment of the present disclosure, the antenna control method of the electronic device further includes the following operations: obtaining a broadcast signal from a base station, and then determining a transmission scenario that the strength of the transmission signal satisfies from the first transmission scenario and the second transmission scenario based on the signal parameters in the broadcast signal. For example, the broadcast information is encoded at a lower coding rate to ensure that the receiving end can obtain accurate signal parameters. The signal parameters may include the coding method, the number of data paths, the signal strength, etc. The electronic device may determine whether the current transmission scenario is the first transmission scenario or the second transmission scenario based on the signal parameters, and then control the switching unit action based on the current transmission scenario to control the on and off of the second signal transmission path.

[0074] The embodiments of the present disclosure are described above. However, these embodiments are only for illustrative purposes and are not intended to limit the scope of the present disclosure. Although the embodiments are described above, this does not mean that the measures in the various embodiments cannot be used in combination to advantage.
