[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority to the Chinese patent application filed with the State Intellectual Property Office of the People's Republic of China on February 20, 2024, with application number 202410190501.4 and application name "A Communication Method and Device", the entire contents of which are incorporated by reference into this application. Technical Field

[0003] The present application relates to the field of wireless communication technology, and in particular to a communication method and device. Background Art

[0004] User equipment (UE) can achieve communication through multiple antennas; wherein, the multiple antennas can be placed at any position on the four sides of the UE, such as the top area, the bottom area, the left side area, and the right side area.

[0005] When a user holds a UE, the hand absorbs the electromagnetic waves radiated by the antenna, which can cause a decrease in the antenna's transceiver performance and affect the UE's communication quality. Therefore, it is worth considering how to improve the communication performance of electronic devices.

[0006] Summary of the Invention

[0007] The present application proposes a communication method and apparatus, which can take into account the impact of hand gripping posture on the antenna's transceiver performance to improve the communication performance of the UE.

[0008] In a first aspect, the present application provides a communication method, which can be applied to an electronic device comprising a first transmitting device, a first receiving device, and N antennas, where N is a positive integer. The method can be performed by the electronic device or by a corresponding communication device of the electronic device, without limitation. Taking the electronic device as an example, the method may include: transmitting a first signal via the first transmitting device; receiving the first signal and a second signal via the first receiving device, where the second signal is a reflected signal of the first signal received by the first receiving device after being reflected by a user's grip; and when it is determined, based on the first and second signals, that the user's grip meets a preset condition for the first grip, controlling a target antenna held in the first grip according to a preset control method, where the target antenna is at least one of the N antennas. The preset condition for the first grip includes at least one of the following: a preset condition for reflected signal strength and a preset condition for reflection path; the reflection path is determined based on the reception time of the first signal and the reception time of the second signal, where the first signal is, for example, the first signal received by the first receiving device, and the second signal is, for example, the second signal received by the first receiving device. The preset control mode includes: increasing the transmit power of the target antenna; increasing the receive gain of the target antenna; decreasing the priority of the target antenna; or switching from a first communication mode to a second communication mode, where the first communication mode is the communication mode corresponding to the target antenna. The second communication mode may be, for example, another communication mode corresponding to an antenna other than the target antenna.

[0009] In this method, the signal transceiver can detect the user's grip based on the signal strength and / or reflection path, and then determine the antenna affected by the user's grip as the target antenna; then, by controlling the target antenna, the communication performance of the electronic device can be guaranteed or improved.

[0010] In one possible implementation, the first grip is gripping a first side of the electronic device; the first transmitting device, the first receiving device, and the target antenna are located on the first side. The user grip satisfies the preset conditions for the first grip, including: the signal strength of the second signal is greater than a first preset signal strength threshold; and / or the reflection path of the second signal is less than or equal to the first preset reflection path.

[0011] In this embodiment, by detecting that the reflected signal intensity is large and / or the reflected path is small, it can be determined that the user's grip is on the same side as the first receiving device, thereby enabling detection of the user's grip to achieve more accurate control of the target antenna.

[0012] In a possible embodiment, the electronic device further includes a second receiving device; wherein the second receiving device and the first receiving device are located on parallel sides. The method further includes: receiving the first signal and the third signal through the second receiving device, wherein the third signal is a reflected signal received by the second receiving device after the first signal is reflected by the user's grip. Wherein, the user's grip meets the preset conditions of the first grip, and further includes: the signal strength of the third signal is less than or equal to the second preset signal strength threshold, and the second preset signal strength threshold is less than or equal to the first preset signal strength threshold; and / or the reflection path of the third signal is greater than the second preset reflection path, and the second preset reflection path is greater than the first preset reflection path.

[0013] In this embodiment, by analyzing the signals received by multiple receiving devices, the accuracy of determining the user's grip posture can be improved to ensure more accurate control of the target antenna.

[0014] In one possible embodiment, the first grip is to hold the second side of the electronic device; the first transmitting device and the first receiving device are located on the first side of the electronic device, and the target antenna is located on the second side; the second side and the first side are located on different sides. Wherein, the user grip meets the preset conditions of the first grip, including: the signal strength of the second signal is less than or equal to the first preset signal strength threshold, and greater than the second preset signal strength threshold; and / or, the reflection path of the second signal is greater than the first preset reflection path, and less than or equal to the second preset reflection path. Optionally, the different sides may be located on vertical sides, for example, or at different positions other than the first side.

[0015] In this embodiment, by detecting a medium reflected signal strength and / or a medium reflected path, it can be determined that the user's grip is located on a different side from the first receiving device, such as a vertical side or the back of the electronic device. Therefore, the user's grip can be detected, enabling more accurate control of the target antenna.

[0016] In a possible embodiment, the electronic device further includes a second receiving device; wherein the second receiving device is located on parallel sides to the first receiving device. The method further includes: receiving the first signal and the fourth signal through the second receiving device, wherein the fourth signal is a reflected signal received by the second receiving device after the first signal is reflected by the user's grip. Wherein, the user's grip meets the preset conditions of the first grip, and further includes: the signal strength of the fourth signal is greater than the second preset signal strength threshold and less than or equal to the first preset signal strength threshold; and / or the reflection path of the fourth signal is less than or equal to the second preset reflection path and greater than the first preset reflection path.

[0017] In this embodiment, by analyzing the signals received by multiple receiving devices, it is detected that the reflected signal strength is medium and / or the reflection path is medium, so it can be more accurately judged that the user's grip is on the same side as the first receiving device, thereby improving the accuracy of determining the user's grip to ensure more accurate control of the target antenna.

[0018] In a possible embodiment, the electronic device also includes a second transmitting device and a third receiving device; the method also includes: sending a fifth signal through the second transmitting device; receiving the fifth signal and a sixth signal through the third receiving device, the sixth signal being a reflected signal of the fifth signal received by the third receiving device after being transmitted through the user grip; determining that the user grip meets the preset conditions of the first grip based on the first signal and the second signal includes: determining that the user grip meets the preset conditions of the first grip based on the first signal and the second signal, the fifth signal and the sixth signal.

[0019] In this embodiment, through multiple pairs of signal transceiver devices, more accurate detection of the user's grip can be achieved based on the signal strength and / or reflection path of the signal to ensure more accurate control of the target antenna, thereby ensuring or improving the communication performance of the electronic device.

The second side and the first side are located on different sides, and the second side and the third side are located on different sides. The user grip satisfies the preset conditions of the first grip and further includes: the signal strength of the sixth signal is greater than a fourth preset signal strength threshold and less than or equal to the third preset signal strength threshold; and / or the reflection path of the sixth signal is less than or equal to the fourth preset reflection path and greater than the third preset reflection path. Optionally, the third preset signal strength threshold may be different from or the same as the first preset signal strength threshold. Alternatively, the fourth preset signal strength threshold may be different from or the same as the second preset signal strength threshold. The preset reflection path and the preset signal strength are similar and will not be further described here.

[0021] In this embodiment, by detecting that the reflected signal strength is medium and / or the reflected path is medium, it can be determined that the user's grip and the first receiving device are located on different sides, thereby enabling detection of the user's grip to achieve more accurate control of the target antenna.

[0022] In a possible embodiment, the target antenna corresponding to the first grip is determined according to the following method: based on the reflection path of the second signal and the reflection path of the sixth signal, the target holding range of the first grip for the second side is determined; and the antenna included in the target holding range is determined as the target antenna.

[0078] References to "one embodiment" or "some embodiments" etc. described in this specification mean that one or more embodiments of the present application include specific features, structures or characteristics described in conjunction with the embodiment. Therefore, the phrases "in one embodiment", "in some embodiments", "in other embodiments", etc. that appear in different places in this specification do not necessarily all refer to the same embodiment, but mean "one or more but not all embodiments", unless otherwise specifically emphasized in other ways, and the "implementation methods" in this specification are the same as above.

[0080] Figure 1A is a schematic diagram of the antenna distribution on an electronic device. For example, the electronic device may include antenna 101 in the top area, antenna 102, antenna 103, and antenna 104 in the right side area, antenna 105 in the bottom area, and antenna 106, antenna 107, and antenna 108 in the left area. It is understood that the embodiments of the present application do not limit the specific distribution locations of the antennas, and the actual distribution locations and number of antennas can be determined based on the type of electronic device, etc. For example, in addition to being located on the sides of the electronic device, the antennas can also be located on the back of the electronic device, etc., and this application does not limit this.

[0081] When using electronic devices, such as holding a mobile phone in your hand or putting the phone to your ear to make a call, body parts such as your hands or ears will absorb the electromagnetic waves radiated by the antenna, thereby affecting the antenna's transceiver performance and affecting the communication quality of the mobile phone.

[0082] For example, Figure 1B is a schematic diagram of user grip 1. Figure 1B shows a scenario where user grip 1 is holding the long side and bottom of the phone. As can be seen from Figure 1B, the antennas held by user grip 1 include: antenna 103, antenna 104, antenna 105, antenna 106, antenna 107, and antenna 108. That is, the electromagnetic waves of antenna 101 and antenna 102 are not affected by user grip 1.

[0083] For another example, Figure 1C is a schematic diagram of user grip 2. Figure 1C shows a scenario where user grip 2 is holding the top and bottom of the phone horizontally with both hands. As can be seen from Figure 1C, the antennas held by user grip 2 include: antenna 101, antenna 105, antenna 106, and antenna 108. That is, the electromagnetic waves of antenna 102, antenna 103, antenna 104, and antenna 107 are not affected by user grip 2.

[0084] For another example, Figure 1D is a schematic diagram of user grip 3. Figure 1D shows a scenario where user grip 3 is holding the top of the phone with one hand. As can be seen from Figure 1D, the antennas held by user grip 3 include antenna 101 and antenna 108, that is, the electromagnetic waves of antenna 102, antenna 103, antenna 104, antenna 105, antenna 106, and antenna 107 are not affected by user grip 3.

[0085] For another example, Figure 1E is a schematic diagram of user grip 4. Figure 1E shows a scenario where user grip 4 is holding the bottom of the phone with one hand. As can be seen from Figure 1E , the antennas held by user grip 4 include antenna 105 and antenna 106, that is, the electromagnetic waves of antenna 101, antenna 102, antenna 103, antenna 104, antenna 107, and antenna 108 are not affected by user grip 4.

[0086] For another example, Figure 1F is a schematic diagram of user grip 5. Figure 1F shows a scenario where user grip 5 is holding the long side of the phone. As can be seen from Figure 1F, the antennas held by user grip 5 include: antenna 103, antenna 104, antenna 106, and antenna 107. That is, the electromagnetic waves of antenna 101, antenna 102, antenna 105, and antenna 108 are not affected by user grip 5.

[0087] Other user gripping postures can be found in Figures 1B to 1F. The user gripping posture of clamping the phone to the ear is not described in detail here. It should be understood that this application does not limit the specific gripping posture.

[0088] As can be seen from Figures 1B to 1F, the antenna held in a user's grip can be understood as covering part or most of the area within a certain distance, for example, an area greater than or equal to a preset area threshold. Therefore, due to occlusion by body parts such as hands, the signal transmitted by the antenna is lost, resulting in performance degradation. Therefore, determining the user's grip is crucial to ensuring the communication performance of electronic devices.

[0089] In view of the above-mentioned problems, an embodiment of the present application provides a communication method, comprising: transmitting a signal via a transmitting device included in an electronic device; receiving the signal from the transmitting device and a signal reflected by the user's grip via a receiving device included in the electronic device; then, by analyzing the signal strength and reflection path of the reflected signal, the user's grip can be determined. In this way, the antenna can be controlled based on the acquired user grip. For example, when the antenna is used as a transmitting antenna, the transmit power of the held antenna is increased; or when the antenna is used as a receiving antenna, the receive gain of the target antenna is increased; or the transmission or reception of the held antenna is disabled. For another example, lowering the priority of the held antenna can also be understood as giving priority to transmitting or receiving over an antenna that is not held. For another example, if the held antenna is in a cellular network communication mode, the cellular network communication mode can be switched to a wireless network communication mode. In this method, the user's grip is acquired via the transmitting and receiving devices, and the antenna is adjusted based on the user's grip, thereby improving the communication performance of the electronic device.

[0094] FIG2 shows a schematic diagram of the hardware structure of a possible electronic device. Wherein, the electronic device 200 includes components such as a radio frequency (RF) circuit 210, a power supply 220, a processor 230, a memory 240, an input unit 250, a display unit 260, an audio circuit 270, a communication interface 280, and a wireless fidelity (Wi-Fi) module 290. Those skilled in the art will appreciate that the hardware structure of the electronic device 200 shown in FIG2 does not constitute a limitation on the electronic device 200. The electronic device 200 provided in the embodiment of the present application may include more or fewer components than shown, may combine two or more components, or may have different component configurations. The various components shown in FIG2 may be implemented in hardware, software, or a combination of hardware and software, including one or more signal processing and / or application-specific integrated circuits.

[0095] The following is a detailed introduction to the various components of the electronic device 200 with reference to FIG. 2 :

[0096] The RF circuit 210 can be used for receiving and sending data during communication or calls. In particular, after receiving the downlink data from the base station, the RF circuit 210 sends it to the processor 230 for processing; in addition, the uplink data to be sent is sent to the base station. Generally, the RF circuit 210 includes but is not limited to an antenna, at least one amplifier, a transceiver, a coupler, a low noise amplifier (LNA), a duplexer, etc. In the embodiment of the present application, the number and position of the antennas included in the RF circuit 210 are not limited, and can be determined according to the factory preset of the electronic device 200. It should be understood that the antenna included in the RF circuit 210 can enable the electronic device 200 to implement a cellular network communication mode.

[0097] In addition, the RF circuit 210 can also communicate with other devices via a wireless communication network. The wireless communication can use any communication standard or protocol, including but not limited to Global System of Mobile Communications (GSM), General Packet Radio Service (GPRS), Code Division Multiple Access (CDMA), Wideband Code Division Multiple Access (WCDMA), Long Term Evolution (LTE), email, Short Messaging Service (SMS), etc.

[0098] The electronic device 200 can also implement communication services and interact with other electronic devices. Therefore, the electronic device 200 needs to have a data transmission function, that is, the electronic device 200 needs to include a communication module. Although Figure 2 shows communication modules such as the RF circuit 210, the Wi-Fi module 290, and the communication interface 280, it is understandable that the electronic device 200 contains at least one of the above components or other communication modules (such as a Bluetooth module) for implementing communication to perform data transmission.

[0099] For example, when the electronic device 200 is a mobile phone, the electronic device 200 may include the RF circuit 210, and may also include the Wi-Fi module 290, or may include a Bluetooth module (not shown in Figure 2); when the electronic device 200 is a computer, the electronic device 200 may include the communication interface 280, and may also include the Wi-Fi module 290, or may include a Bluetooth module (not shown in Figure 2); when the electronic device 200 is a tablet computer, the electronic device 200 may include the Wi-Fi module, or may include a Bluetooth module (not shown in Figure 2).

[0100] Wi-Fi technology is a short-range wireless transmission technology. The electronic device 200 can connect to an access point (AP) through the Wi-Fi module 290 to achieve access to the data network. The Wi-Fi module 290 can be used for receiving and sending data during the communication process. Generally, the Wi-Fi module 290 also includes but is not limited to an antenna, etc. In the embodiment of the present application, the number and position of antennas included in the Wi-Fi module 290 are not limited, and can be determined according to the factory preset of the electronic device 200. Optionally, the Bluetooth module can share an antenna with the Wi-Fi module 290. Alternatively, the Bluetooth module may also include an antenna.

[0101] The electronic device 200 can be physically connected to other devices via the communication interface 280. Optionally, the communication interface 280 is connected to the communication interface of the other device via a cable to achieve data transmission between the electronic device 200 and the other device.

[0102] The memory 240 can be used to store software programs and modules. The processor 230 executes various functional applications and data processing of the electronic device 200 by running the software programs and modules stored in the memory 240. Optionally, the memory 240 may mainly include a program storage area and a data storage area. Among them, the program storage area can store an operating system (mainly including the corresponding software programs or modules of the kernel layer, system layer, application framework layer and application layer).

[0103] In addition, the memory 240 may include a high-speed random access memory and may also include a non-volatile memory, such as at least one disk storage device, a flash memory device, or other volatile solid-state storage devices.

[0104] The processor 230 is the control center of the electronic device 200. It connects various components using various interfaces and lines, executes or runs software programs and / or modules stored in the memory 240, and calls data stored in the memory 240 to perform various functions of the electronic device 200 and process data, thereby implementing various services based on the electronic device 200. In the embodiment of the present application, the processor 230 can be used to implement the communication method provided in the embodiment of the present application.

[0105] As shown in Figure 2, the electronic device 200 also includes an audio circuit 270, a microphone 271 and a speaker 272, which can provide an audio interface between the user and the electronic device 200. The audio circuit 270 can be used to convert audio data into a signal that can be recognized by the speaker 272, and transmit the signal to the speaker 272, which is converted into a sound signal for output by the speaker 272. The microphone 271 is used to collect external sound signals (such as the sound of a person speaking or other sounds, etc.), and convert the collected external sound signals into signals that can be recognized by the audio circuit 270 and send them to the audio circuit 270. The audio circuit 270 can also be used to convert the signal sent by the microphone 271 into audio data, and then output the audio data to the RF circuit 210 to be sent to, for example, another electronic device, or output the audio data to the memory 240 for subsequent further processing. In the embodiment of the present application, the transmitting device can, for example, reuse the speaker 272, and the receiving device can, for example, reuse the microphone 271; it can be understood that the signal transmitted by the transmitting device can be the sound wave signal transmitted by the speaker 272, and the signal received by the receiving device can be the sound wave signal received by the microphone 271.

[0106] Although not shown, the electronic device 200 may further include a camera, at least one sensor, etc., which will not be described in detail here. The at least one sensor may include but is not limited to a gyroscope sensor, a gravity sensor, a pressure sensor, an air pressure sensor, an acceleration sensor, a distance sensor, a fingerprint sensor, a touch sensor, a temperature sensor, etc.

[0107] In order to facilitate understanding of the communication method provided by the present application, the implementation process of the method provided by the present application is introduced below in combination with the contents shown in Figures 3 to 7.

[0108] In a possible example, Figure 3 is a schematic diagram of the structure of the transmitting device and the receiving device provided in an embodiment of the present application. As shown in Figure 3, the electronic device 200 may include a transmitting device 301, a receiving device 302 and a processor 230 (not shown in Figure 3). As shown in Figure 3, the transmitting device 301 and the receiving device 302 may be located on the same side, such as the top area of ​​the electronic device; the user grip shown in Figure 3 is the user grip 3 shown in Figure 1D, that is, holding the top area of ​​the mobile phone with one hand. It should be understood that although not shown in Figure 3, the electronic device 200 may also include N antennas, where N is a positive integer. Among them,

[0109] (1) Transmitting device 301, configured to transmit a first signal. It should be noted that transmitting device 301 may transmit the first signal by scattering, or by scattering within a certain angle. It should be understood that the transmission direction and number of the first signal are not limited in the embodiments of the present application. As shown in FIG3 , the first signal may be transmitted in at least two directions.

[0110] (2) Receiving device 302, configured to receive a first signal; and further configured to receive a second signal, wherein the second signal is a reflected signal of the first signal received by receiving device 302 after being reflected by the user's grip. As shown in FIG3 , receiving device 302 can receive the unreflected first signal from transmitting device 301, i.e., the transmitted signal; and can also receive the second signal from transmitting device 301 after being reflected by the user's grip, i.e., the reflected signal.

[0111] (3) The processor 230 is configured to obtain the first signal and the second signal from the receiving device 302, and determine the user's grip posture based on the first signal and the second signal. For example, the processor 230 may determine the user's grip posture by, but not limited to, the following methods, including:

[0112] Mode A: Determine the reflected signal strength of the second signal. Exemplarily, when receiving the second signal, the receiving device 302 may obtain the signal strength of the second signal, that is, obtain the reflected signal strength of the second signal.

[0113] Method B, determine the reflection path of the second signal. Exemplarily, the receiving device 302 can obtain the first receiving time of receiving the first signal, and can also obtain the second receiving time of receiving the second signal. According to the time delay between the first receiving time and the second receiving time, the reflection path of the second signal can be determined. It can be understood that the greater the time delay, the greater the reflection path; the smaller the time delay, the smaller the reflection path. For example, the first signal can be the first signal received by the receiving device 302, and the second signal can be the second signal received by the receiving device 302. Therefore, the second signal can also be understood as the reflected signal first received by the receiving device 302. It can be understood that the signal transmitted by the transmitting device 301 can include multiple sending directions. Therefore, there may be multiple reflected signals that the receiving device 302 can receive. The receiving device 302 can also combine multiple reflected signals to determine the user's grip posture. This application does not limit this.

[0114] As shown in Figure 3, the reflected signal strength of the second signal (for example, it can be expressed as ρ1) is stronger, for example, ρ1 is greater than the first preset signal strength threshold (for example, it can be expressed as P1); the reflection path of the second signal (for example, it can be expressed as d1) is shorter, for example, d1 is less than or equal to the first preset reflection path (for example, it can be expressed as D1).

[0115] Figure 3 takes the scenario in which the transmitting device 301 and the receiving device 302 are both located in the top area, and the user's grip also holds the top area as an example. It should be understood that the transmitting device and the receiving device can also be both located in the bottom area, and the user's grip also holds the bottom area; or, the transmitting device and the receiving device can be both located in the side area, and the user's grip also holds the side area. This application will not repeat the introduction of other scenarios.

[0116] Exemplarily, the transmitting device 301 may be a speaker located in the top area, for example, and the receiving device 302 may be a microphone located in the top area, for example, and the first signal and the second signal may be sound wave signals.

[0117] In another possible example, Figure 4 is another structural diagram of the transmitting device and the receiving device provided in an embodiment of the present application. As shown in Figure 4, compared with Figure 3, the electronic device 200 may include not only a transmitting device 301, a receiving device 302 and a processor 230 (not shown in Figure 4), but also a receiving device 402. Among them, the processing of the transmitting device 301 and the receiving device 302 can refer to Figure 3 and will not be repeated here. The receiving device 402 can be located on a parallel side with the receiving device 302, for example, located in the bottom area of ​​the electronic device; the user grip shown in Figure 4 is still the user grip 3 shown in Figure 1D, that is, holding the top area of ​​the mobile phone with one hand. It should be understood that although not shown in Figure 4, the electronic device 200 may also include N antennas, where N is a positive integer. Among them,

[0118] (4) Receiving device 402, configured to receive the first signal; and further configured to receive a third signal, wherein the third signal is a reflected signal received by receiving device 402 after the first signal is reflected by the user's grip. As shown in FIG4 , receiving device 402 can receive the unreflected first signal from transmitting device 301, i.e., the transmitted signal; and can also receive the third signal from transmitting device 301 after the first signal is reflected by the user's grip, i.e., the reflected signal.

[0119] In addition, as shown in FIG4 , it can be understood that the transmitting device 301 may have at least three transmitting directions.

[0120] Based on the structural diagram described in FIG4 , the processor 230 is further configured to obtain the first signal and the third signal from the receiving device 402 and determine the user's grip posture based on the first signal and the third signal. For example, the processor 230 may determine the user's grip posture by, but not limited to, the following methods, including:

[0121] Mode A: Determine the reflected signal strength of the third signal. Exemplarily, when receiving the third signal, the receiving device 402 may obtain the signal strength of the third signal, that is, obtain the reflected signal strength of the third signal.

[0122] Method B, determine the reflection path of the third signal. Exemplarily, the receiving device 402 can obtain the first receiving time of receiving the first signal, and can also obtain the third receiving time of receiving the third signal. According to the time delay between the first receiving time and the third receiving time, the reflection path of the third signal can be determined. It can be understood that the greater the time delay, the greater the reflection path; the smaller the time delay, the smaller the reflection path. For example, the first signal can be the first signal received by the receiving device 402, and the third signal can be the second signal received by the receiving device 402. Therefore, the third signal can also be understood as the reflected signal first received by the receiving device 402. It can be understood that the signal transmitted by the transmitting device 301 can include multiple sending directions, so there may also be multiple reflected signals that the receiving device 402 can receive. The receiving device 402 can also combine multiple reflected signals to determine the user's grip posture, which is not limited in this application.

[0123] As shown in Figure 4, the reflected signal strength of the third signal (for example, it can be expressed as ρ2) is weak, for example, ρ2 is less than or equal to the second preset signal strength threshold (for example, it can be expressed as P2), where P2 is less than P1; the reflection path of the third signal (for example, it can be expressed as d2) is longer, for example, d2 is greater than the second preset reflection path (for example, it can be expressed as D2), where D2 is greater than D1.

[0124] Optionally, the processor 230 may determine, based on the signal received by the receiving device 402, that the user's grip is a grip that is parallel to the receiving device 402. It should be understood that the electronic device shown in FIG4 may not include the receiving device 302 in this scenario.

[0125] Alternatively, the processor 230 may also jointly determine, based on the signal received by the receiving device 302 and the signal received by the receiving device 402, that the user's grip is a grip on the same side as the receiving device 302 and a grip on a parallel side to the receiving device 402, thereby improving the accuracy of detecting the user's grip.

[0126] Figure 4 takes the scenario in which the transmitting device 301 and the receiving device 302 are both located in the top area, the receiving device 402 is located in the bottom area, and the user's grip also holds the top area as an example. It should be understood that the transmitting device 301 and the receiving device 302 can also be both located in the bottom area, the receiving device 402 is located in the top area, and the user's grip also holds the bottom area. This application will not repeat the introduction of other scenarios.

[0127] Exemplarily, the receiving device 402 may be a microphone located in the bottom area, and the first signal and the third signal may be sound wave signals.

[0128] In another possible example, Figure 5 is another structural diagram of the transmitting device and the receiving device provided in an embodiment of the present application. As shown in Figure 5, the electronic device 200 may include a transmitting device 501, a receiving device 502 and a processor 230 (not shown in Figure 5). As shown in Figure 5, the transmitting device 501 and the receiving device 502 may be located on the same side, for example, at the bottom area of ​​the electronic device; the user grip shown in Figure 5 is the user grip 3 shown in Figure 1D, that is, holding the top area of ​​the mobile phone with one hand. Among them, the processing of the transmitting device 501, the receiving device 502 and the processor 230 can refer to Figures 3 and 4. It should be understood that although not shown in Figure 5, the electronic device 200 may also include N antennas, where N is a positive integer.

[0129] As shown in Figure 5, the reflected signal strength of the reflected signal received by the receiving device 502 (for example, it can be expressed as weak, for example, ρ3 is less than or equal to the second preset signal strength threshold (for example, it can be expressed as P2); the reflection path of the reflected signal received by the receiving device 502 (for example, it can be expressed as d3) is longer, for example, d3 is greater than the second preset reflection path (for example, it can be expressed as D2).

[0130] In another possible example, Figure 6 is another structural diagram of the transmitting device and receiving device provided in an embodiment of the present application. As shown in Figure 6, the electronic device 200 may include a transmitting device 301, a receiving device 302, a transmitting device 601, a receiving device 602 and a processor 230 (not shown in Figure 6). As shown in Figure 6, the transmitting device 301 and the receiving device 302 may be located on the same side, such as the top area of ​​the electronic device; the transmitting device 601 and the receiving device 602 may be located on the same side, such as the bottom area of ​​the electronic device; wherein the transmitting device 301 and the receiving device 302, and the transmitting device 601 and the receiving device 602 are located on parallel sides. The user grip shown in Figure 6 is the user grip 2 shown in Figure 1C, that is, holding the top and bottom of the mobile phone horizontally with both hands. Among them, the processing of the transmitting device 301, the receiving device 302, the transmitting device 601, the receiving device 602 and the processor 230 can refer to Figures 3 to 5. Optionally, the receiving device 602 may be the same receiving device as the receiving device 402 in Figure 4. It should be understood that, although not shown in FIG. 6 , the electronic device 200 may further include N antennas, where N is a positive integer.

[0131] It should be understood that receiving device 302 can receive signals from transmitting device 301 or from transmitting device 601. Similarly, receiving device 602 can receive signals from transmitting device 301 or from transmitting device 601. For example, transmitting device 301 and transmitting device 601 can transmit signals at different times to avoid interference. For another example, in a scenario where transmitting device 301 and transmitting device 601 transmit signals at the same time, they can transmit orthogonal signals to avoid interference. For example, orthogonal signals may include, but are not limited to, signals with different frequencies or different codewords.

[0132] Exemplarily, a transmitting device 601 is configured to transmit a fifth signal. A receiving device 602 is configured to receive the fifth signal and further configured to receive a sixth signal, the sixth signal being a reflected signal of the fifth signal received by the receiving device 602 after being reflected by the user's grip. As shown in FIG6 , the receiving device 602 can receive the unreflected fifth signal from the transmitting device 601, i.e., the transmitted signal; and can also receive the sixth signal from the transmitting device 601 after being reflected by the user's grip, i.e., the reflected signal.

[0133] Optionally, as shown in FIG6 , if the reflected signal received by the receiving device 302 from the transmitting device 301 is stronger and the reflected path is shorter, it can be determined that the user is holding the top area. And / or if the reflected signal received by the receiving device 602 from the transmitting device 301 is weaker and the reflected path is longer, it can be determined that the user is holding the top area.

[0134] Alternatively, as shown in FIG6 , if the reflected signal received by the receiving device 302 from the transmitting device 601 is weak and the reflected path is long, it can be determined that the user is holding the bottom area. Alternatively, if the reflected signal received by the receiving device 602 from the transmitting device 601 is strong and the reflected path is short, it can be determined that the user is holding the bottom area.

[0135] Therefore, the user's grip posture 2 of holding the top and bottom areas of the mobile phone horizontally with both hands can be determined through the transmitting device 301, the receiving device 302, the transmitting device 601, and the receiving device 602.

[0136] In addition, when the electronic device detects the user's grip posture 2 of holding the top and bottom of the phone horizontally with both hands, it can also combine sensors such as a gyroscope sensor, a gravity sensor, and an acceleration sensor to detect the user's grip direction of the electronic device, thereby determining whether the antennas 108 and 106 included on the left side of the electronic device are being held, or the antennas 102 and 104 included on the right side are being held. In this way, the target antenna held by the user's grip posture can be further accurately determined.

[0137] In another possible example, Figure 7 is another signal schematic diagram based on the structure shown in Figure 6. The user grip shown in Figure 7 is the user grip 5 shown in Figure 1F, that is, holding the long side of the phone. It should be understood that although not shown in Figure 7, electronic device 200 may also include N antennas, where N is a positive integer.

[0138] Optionally, as shown in FIG7 , the reflected signal (e.g., ρ4) received by the receiving device 302 from the transmitting device 301 is medium, e.g., ρ4 is less than or equal to P1, and ρ4 is greater than P2; the reflected path (e.g., d4) is medium, e.g., d4 is greater than D1, and d4 is less than or equal to D2, thereby determining that the user is holding the side area. It can be understood that compared to the scenario of holding the top area, the reflected signal from the transmitting device 301 received by the receiving device 302 is weakened; and compared to the scenario of holding the bottom area, the reflected signal from the transmitting device 301 received by the receiving device 302 is enhanced. It can also be understood that compared to the scenario of holding the top area, the reflected path from the transmitting device 301 received by the receiving device 302 is increased; and compared to the scenario of holding the bottom area, the reflected path from the transmitting device 301 received by the receiving device 302 is shortened.

[0139] Alternatively, as shown in FIG7 , the reflected signal (e.g., represented by ρ5) received by the receiving device 602 from the transmitting device 601 is medium, e.g., ρ5 is less than or equal to the third preset signal strength threshold (e.g., represented by P3), and ρ5 is greater than the fourth preset signal strength threshold (e.g., represented by P4); the reflection path (e.g., represented by d5) is medium, e.g., d5 is greater than the third preset reflection path (e.g., represented by D3), and d5 is less than or equal to the fourth preset reflection path (e.g., represented by D4), thereby determining that the user is holding the side area. It can be understood that compared to the scenario of holding the bottom area, the reflected signal from the transmitting device 601 received by the receiving device 602 is weakened; and compared to the scenario of holding the top area, the reflected signal from the transmitting device 601 received by the receiving device 602 is enhanced. It can also be understood that, compared with the scenario of holding the bottom area, the reflection path received by the receiving device 602 from the transmitting device 601 is increased; and compared with the scenario of holding the top area, the reflection path received by the receiving device 602 from the transmitting device 601 is shortened.

[0140] It should be noted that P3 can be different from or the same as P1. For example, if the signal strength and gain transmitted by transmitter 301 and transmitter 601 are the same, P3 and P1 can be the same. Alternatively, P4 can be different from or the same as P2. For example, if the signal strength and gain transmitted by transmitter 301 and transmitter 601 are the same, P4 and P2 can be the same. The preset reflection path and the preset signal strength are similar and will not be further described here.

[0141] For example, processor 230 may also determine the specific range of the side edge being gripped by the user based on the reflection path d4 of the reflected signal received by receiving device 302 from transmitting device 301 and the reflection path d5 ​​of the reflected signal received by receiving device 602 from transmitting device 601. For example, if d4 is less than d5, the user may be determined to be gripping the side edge slightly above the upper portion. For another example, if d4 is greater than d5, the user may be determined to be gripping the side edge slightly above the upper portion. For example, if d4 is equal to d5, the user may be determined to be gripping the side edge in the middle portion.

[0142] From the contents described in Figures 3 to 7 above, it can be seen that on an electronic device, the user's grip posture can be detected by at least one transmitting device and at least one receiving device. In this way, combined with the influence relationship between each user's grip posture and the antenna described in Figures 1B to 1F, the target antenna affected by the user's grip posture can be determined. Then, the electronic device can control the target antenna, thereby ensuring the communication performance of the electronic device. Exemplarily, the control of the target antenna may include but is not limited to: increasing the transmission power of the target antenna, thereby increasing the transmission power of the electromagnetic waves absorbed by the hand; or, increasing the receiving gain of the target antenna, thereby increasing the receiving gain of the electromagnetic waves absorbed by the hand; or, reducing the use priority of the target antenna, thereby giving priority to antennas outside the grip range; or, switching from the first communication mode to the second communication mode, where the first communication mode is the communication mode corresponding to the target antenna, for example, the first communication mode is a cellular network, and the second communication mode may be Wi-Fi.

[0143] For example, Figure 8 is a flow chart of a communication method provided in an embodiment of the present application. The method can be applied to an electronic device, wherein the electronic device includes a first transmitting device, a first receiving device, and N antennas, where N is a positive integer. For example, the first transmitting device can be the transmitting device 301, transmitting device 501, or transmitting device 601 described in the aforementioned embodiment, and the first receiving device can be the receiving device 302, receiving device 402, receiving device 502, or receiving device 602 described in the aforementioned embodiment. The process may include:

[0144] Step 801: Send a first signal through the first transmitting device; receive the first signal and a second signal through the first receiving device, where the second signal is a reflected signal of the first signal received by the first receiving device after being reflected by the user's grip.

[0145] Step 802: The processor obtains the first signal and the second signal received by the first receiving device.

[0146] Step 803: When the processor determines, based on the first signal and the second signal, that the user's grip meets a preset condition for a first grip, the processor controls a target antenna held in the first grip according to a preset control method. The target antenna is at least one of the N antennas.

[0147] Exemplarily, the preset condition of the first grip posture includes at least one of the following conditions: a preset condition of the reflection signal strength, a preset condition of the reflection path. For example, the first grip posture may include several possible grip postures as shown in Table 1, and the corresponding preset conditions may be as shown in Table 1 below:

[0148] Table 1

[0149] Wherein, ρ represents the reflected signal strength of the second signal, and d represents the reflected path of the second signal. The deployment positions of the first transmitting device and the first receiving device may be acquired in advance. It can be understood that when the first grip is to hold the side where the first receiving device is located, the reflection path is shorter and the reflected signal strength is greater; when the first grip is to hold the side different from the first receiving device, such as the vertical side, the reflection path is medium and the reflected signal strength is medium; when the first grip is to hold the parallel side of the first receiving device, the reflection path is longer and the reflected signal strength is smaller. It can be concluded that based on the known deployment position of the first receiving device, the user's grip can be determined according to the reflected signal strength and / or the reflection path.

[0150] Exemplarily, the preset control method includes but is not limited to one of the following methods:

[0151] (A) Increasing the transmit power of the target antenna. Referring to FIG. 1B , the antennas held in the first grip include antennas 103 through 108. When at least one of antennas 103 through 108 functions as a transmit antenna, the transmit power of the antennas 103 through 108 functioning as the transmit antenna can be increased.

[0152] (B) Increasing the receiving gain of the target antenna. As shown in FIG. 1B , the antennas held in the first grip posture include antennas 103 to 108 . When at least one of antennas 103 to 108 serves as a receiving antenna, the receiving gain of the antennas 103 to 108 serving as the receiving antenna can be increased.

[0153] (C) Lowering the priority of the target antenna. As shown in FIG1B , the antenna 103 held in the first grip includes antenna 108, and the priority of antenna 103 to antenna 108 can be lowered, that is, antenna 101 and antenna 102 are used to transmit signals first.

[0154] (D) Switching from a first communication mode to a second communication mode, where the first communication mode is the communication mode corresponding to the target antenna. As shown in FIG1B , the antennas held in the first grip posture include antennas 103 to 108. For example, antennas 103 to 108 are antennas corresponding to a cellular network communication mode, and antennas 101 and 102 are antennas corresponding to a Wi-Fi communication mode. Communication using the cellular network communication mode can be switched to communication using the Wi-Fi communication mode. It should be understood that if the electronic device is already communicating using the Wi-Fi communication mode, the current communication mode can be maintained.

[0155] In this method, a signal can be transmitted by a transmitting device, and a non-reflected signal and a reflected signal can be received by a receiving device. The reflected signal strength and / or reflection path of the reflected signal can be determined. Then, by analyzing the reflected signal strength and / or reflection path, the relative positional relationship between the user's grip and the receiving device can be determined, thereby determining the user's grip. As shown in Figures 1B to 1F, based on the determined user grip and known antenna deployment conditions, the target antenna affected by the user's grip can be determined, thereby ensuring or improving the communication performance of the electronic device by controlling the target antenna.

[0156] For another example, Figure 9 is another flow chart of a communication method provided in an embodiment of the present application. Compared to Figure 8, the electronic device to which this method is applied may further include a second receiving device. Exemplarily, the first receiving device may be the receiving device 302 in Figure 4, and the second receiving device may be the receiving device 402 in Figure 4. Another exemplary embodiment, the first receiving device may be the receiving device 302 in Figure 6, and the second receiving device may be the receiving device 602 in Figure 6; or, the first receiving device may be the receiving device 602 in Figure 6, and the second receiving device may be the receiving device 302 in Figure 6. The process may include:

[0157] Step 801: Send a first signal through the first transmitting device; receive the first signal and a second signal through the first receiving device, where the second signal is a reflected signal of the first signal received by the first receiving device after being reflected by the user's grip.

[0158] Step 802: The processor obtains the first signal and the second signal received by the first receiving device.

[0159] Step 901: Send a first signal through the first transmitting device; receive the first signal and a third signal through the second receiving device, where the third signal is a reflected signal of the first signal received by the second receiving device after being reflected by the user's grip.

[0160] Step 902: The processor obtains the first signal and the third signal received by the second receiving device.

[0161] It should be noted that the embodiment of the present application does not limit the execution order between step 901 and step 902 and step 801 and step 802. For example, they can be executed simultaneously.

[0162] Step 903: When the processor determines, based on the first and second signals, and the first and third signals, that the user's grip meets the preset conditions for the first grip, the processor controls the target antenna held in the first grip according to a preset control method. The target antenna is at least one of the N antennas. It should be understood that the processor's processing of the first and third signals can also refer to the preset conditions for the first grip shown in Table 1 and will not be repeated here.

[0163] This method can also be used to jointly determine the user's grip posture through multiple receiving devices, thereby ensuring the accuracy of the determined user's grip posture and thus improving the accuracy of controlling the target antenna.

[0164] For another example, Figure 10 is another flowchart of a communication method provided in an embodiment of the present application. Compared to Figure 8, the electronic device to which this method is applied may further include a second transmitting device and a third receiving device. Exemplarily, the first transmitting device and the first receiving device may be the transmitting device 301 and the receiving device 302 in Figure 6, and the second transmitting device and the third receiving device may be the transmitting device 601 and the receiving device 602 in Figure 6; or, the first transmitting device and the first receiving device may be the transmitting device 301 and the receiving device 602 in Figure 6, and the second transmitting device and the third receiving device may be the transmitting device 601 and the receiving device 302 in Figure 6; and so on. Optionally, the third receiving device may be the same receiving device as the second receiving device in Figure 9. The process may include:

[0165] Step 801: Send a first signal through the first transmitting device; receive the first signal and a second signal through the first receiving device, where the second signal is a reflected signal of the first signal received by the first receiving device after being reflected by the user's grip.

[0166] Step 802: The processor obtains the first signal and the second signal received by the first receiving device.

[0167] Step 1001: Send a fifth signal through the second transmitting device; receive the fifth signal and a sixth signal through the third receiving device, where the sixth signal is a reflected signal of the fifth signal received by the third receiving device after being reflected by the user's grip.

[0168] Exemplarily, the fifth signal and the first signal in step 801 are orthogonal signals, thereby avoiding interference between the signals transmitted by the first transmitting device and the second transmitting device.

[0169] Step 1002: The processor obtains the fifth signal and the sixth signal received by the second receiving device.

[0170] It should be noted that the embodiment of the present application does not limit the execution order between step 1001 and step 1002 and step 801 and step 802. For example, they can be executed simultaneously.

[0171] Step 1003: When the processor determines, based on the first signal, the second signal, the fifth signal, and the sixth signal, that the user's grip meets the preset conditions for the first grip, the processor controls the target antenna held in the first grip according to a preset control method. The target antenna is at least one of the N antennas. It should be understood that the processor's processing of the fifth and sixth signals can also refer to the preset conditions for the first grip shown in Table 1 and will not be repeated here.

[0172] This method can also be used to jointly determine the user's grip posture using multiple transmitting devices and multiple receiving devices. This ensures the accuracy of the determined user's grip posture, thereby improving the accuracy of controlling the target antenna.

[0173] In another exemplary embodiment, the processor can also determine the target holding range of the first grip on the second side based on the reflection path of the second signal and the reflection path of the sixth signal; and determine the antenna included in the target holding range as the target antenna. For example, if the reflection path of the second signal is smaller than the reflection path of the sixth signal, it can be determined that the user is holding the side close to the first receiving device. For another example, if the reflection path of the second signal is larger than the reflection path of the sixth signal, it can be determined that the user is holding the side close to the third receiving device. For example, if the reflection path of the second signal is equal to the reflection path of the sixth signal, it can be determined that the user is holding the middle position between the first receiving device and the third receiving device.

[0174] Based on the above embodiment, the processor triggering the detection of the user's grip posture may include several possible detection conditions, such as but not limited to:

[0175] Condition 1: In scenarios where the electronic device also includes a sensor, the sensor can detect that the amplitude of the electronic device's movement is greater than a preset amplitude threshold. For example, an accelerometer can be used to detect the acceleration of the electronic device along three axes, thereby determining the amplitude of the electronic device's movement. It is understood that when the amplitude of the electronic device's movement is large, the user's grip is more likely to change.

[0176] Condition 2: Detecting that a preset control period has been reached. For example, the processor may periodically trigger detection of the user's grip posture, thereby ensuring real-time control of the antenna.

[0177] Condition 3: A change in the strength of the received signal is detected by the first receiving device or antenna. It can be understood that when the first receiving device or antenna detects a change in the strength of the received signal, the probability of the user's grip changing is relatively high. Based on the above embodiment, taking into account the influence of noise such as environmental noise, the power of the signal transmitted by the transmitting device can be adjusted. For example, when the noise is greater, the power of the signal transmitted by the transmitting device is greater, thereby ensuring a higher signal-to-noise ratio; when the noise is smaller, the power of the signal transmitted by the transmitting device is smaller, thereby saving power consumption of the transmitting device. Taking into account the influence of noise such as environmental noise, the frequency band of the signal transmitted by the transmitting device can also be adjusted. For example, from a plurality of optional frequency bands, a frequency band with less noise can be selected as the frequency band used by the transmitting device, thereby ensuring a higher signal-to-noise ratio.
