The embodiment of the invention provides a communication method, which comprises the following steps: detecting second electronic equipment within a preset area range; determining a target antenna from M antennas of the first electronic device, wherein M is an integer greater than 1; communicating with the second electronic device through the target antenna.

In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention. The embodiments and features of the embodiments of the present invention may be arbitrarily combined with each other without conflict. Also, while a logical order is shown in the flow diagrams, in some cases, the steps shown or described may be performed in an order different than here.

In this embodiment of the present invention, the first electronic device may refer to a device having a large-size display unit, such as a tablet computer (PAD) having a larger-size display unit, and the second electronic device may refer to a PAD, a mobile phone, or another electronic device having the same short-range communication capability as the first electronic device, which is not limited in particular.

In addition, the term "and/or" herein is only one kind of association relationship describing an associated object, and means that there may be three kinds of relationships, for example, a and/or B, which may mean: a exists alone, A and B exist simultaneously, and B exists alone. In addition, the character "/" in this document generally indicates that the preceding and following related objects are in an "or" relationship unless otherwise specified.

In order to better understand the technical solution, the technical solution will be described in detail with reference to the drawings and the specific embodiments.

Referring to fig. 1, an embodiment of the present invention provides a communication method, where the communication method in the embodiment of the present invention may be applied to a first electronic device, that is, an execution subject of each step in the communication method may be the first electronic device. The main flow of the communication method in the embodiment of the present invention is described as follows:

step 101: and detecting the second electronic equipment within the range of the preset area.

The first electronic device in the embodiment of the present invention may refer to an electronic device with a short-range communication capability, that is, the first electronic device may be capable of communicating with an opposite-end electronic device in a short-range communication manner, and when the first electronic device performs short-range communication with the opposite-end electronic device, the first electronic device is implemented by using at least two antennas disposed in the first electronic device.

The short-range communication method is a communication method in which both parties of communication transmission and reception can transmit information by radio waves and the effective distance of information transmission is limited to a short range, and the preset area range in the embodiment of the present invention can be understood as the effective range of information transmission determined by the effective distance.

In the specific implementation process, the short-range communication method may be, for example, a Near Field Communication (NFC) method, a Bluetooth (Bluetooth) communication method, a ZigBee (ZigBee) communication method, a Wi-Fi (Wi-Fi) communication method, or the like. In addition, the effective distance for information transmission is generally different for different types of short-range communication methods, for example, for an NFC communication method, the effective distance for information transmission is generally 10cm, which is not limited in the present invention.

In the embodiment of the present invention, due to the requirement of the communication mode for the effective distance of information transmission, before the first electronic device is to perform, for example, NFC communication with the peer electronic device, it is generally detected whether the peer electronic device exists within a preset area, and if the peer electronic device is detected, it is determined that the detected peer electronic device is also an electronic device with NFC communication capability, and the detected peer electronic device can be determined as the second electronic device.

In the embodiment of the present invention, the following detection method may be adopted to detect the second electronic device within the preset range:

the detecting the second electronic device within the preset range may specifically include:

In this embodiment of the present invention, the antenna array in the first electronic device may be electrically connected to the controller in the first electronic device through the one-out-of-multiple switch, and taking the example that the short-distance wireless communication performed by the first electronic device is NFC communication, the controller may be an NFC controller, that is, an NFC chip, in the first electronic device. The multiple-selection switch can be used for connecting the controller with one antenna (called as a first antenna) in the antenna array at the same time, namely, only one antenna in the first electronic device works at the same time, and the first antenna stops working after being disconnected with the multiple-selection switch, so that the interference caused by the simultaneous working of multiple antennas can be avoided to the maximum extent. In addition, the controller may be configured to provide operating voltages to the antennas in the antenna array to control the first electronic device to perform short-range communication via the first antenna, and may be further configured to process signals transmitted and received via the antennas to obtain corresponding communication information.

That is to say, in the embodiment of the present invention, the first antenna transmits the probe signal and detects whether the feedback signal for the probe signal is received, so as to detect the existence of the peer electronic device, and since the probe signal can only be transmitted within the preset area, if the peer electronic device capable of receiving the probe signal exists within the preset area, the peer electronic device sends the first feedback signal indicating the signal strength of the received probe signal to the first electronic device after receiving the probe signal.

In a specific implementation process, the detection signal may carry the device identification information of the first electronic device, and the first feedback signal may carry the device identification information of the second electronic device, so that the pertinence and accuracy of the signal in the transmission process may be ensured.

In addition, when a plurality of opposite-end electronic devices exist in the preset area range at the same time, the recognition rate of the opposite-end electronic devices can be improved by setting some anti-collision algorithms, and channel interference and collision caused when the plurality of opposite-end electronic devices transmit feedback signals to the first antenna at the same time can be avoided to the greatest extent. For example, the collision avoidance algorithm that can be generally used is a query tree algorithm, a binary search algorithm, an ALOHA algorithm, a collision tree algorithm, etc., and in the specific implementation process, the specific collision avoidance algorithm that is used is not specifically limited.

In addition, the difference between the signal strength of the probe signal transmitted by the first antenna and the probe signal received by the second electronic device may be caused by transmission loss of the signal during transmission, and the transmission loss may include loss caused by factors such as signal transmission distance, signal transmission medium, and signal transmission path.

In the embodiment of the invention, the detection signal transmitted by the first antenna only has a detection function, the detection signal can only be used for indicating the signal intensity of the detection signal without carrying other information, and after the second electronic equipment receives the detection signal, the signal intensity of the received detection signal can be determined in a simple mode without other processing such as analysis and the like. Similarly, after the second electronic device determines the signal strength of the received detection signal, the second electronic device may also transmit the first feedback signal to the first antenna in a similar processing manner, that is, the process of determining the second electronic device through the first antenna is simpler, and since it is not necessary to process information, more time may be saved, thereby shortening the time of the detection process, improving the detection efficiency, and for the electronic device, since it is not necessary to process information, the processing load of the electronic device may also be reduced.

In addition, in addition to the above detection manner, the first electronic device may also have other manners for detecting the second electronic device within the preset area, that is, optionally, in the embodiment of the present invention, the detecting the second electronic device within the preset area may specifically be:

That is, in the embodiment of the present invention, the second electronic device may be detected within the preset area range through at least two detection manners (i.e., the first detection manner and the second detection manner). In a specific implementation process, what kind of method is specifically adopted by the first electronic device to perform detection may be randomly selected by the first electronic device, or may be selected by the user, and the present invention is not particularly limited. The following will specifically explain two detection methods listed in the examples of the present invention.

Optionally, in this embodiment of the present invention, detecting the second electronic device within the preset area range through a first detection method specifically includes:

if the first antenna receives a first feedback signal aiming at the detection signal, determining that the electronic equipment is detected within the preset range, and determining the detected electronic equipment as the second electronic equipment; the first feedback signal is a received signal strength indication signal determined by the electronic device according to the signal strength of the received detection signal.

That is, the first detection method in the embodiment of the present invention is to determine the existence of the peer electronic device by detecting whether the feedback signal for the probe signal is received, and such a detection method has a relatively fast detection process and a relatively high detection efficiency.

Optionally, in this embodiment of the present invention, detecting the second electronic device within the preset area range through a second detection method specifically includes:

That is, the second detection mode is a mode in which a specific request signal is transmitted through the first antenna and whether a response signal corresponding to the request signal is received is detected to determine the presence of the second electronic device within the preset area.

In the second detection mode, at the beginning of detection, that is, after the first antenna is powered on, an electromagnetic field is generated, which may be referred to as an operating field of the first antenna, and an effective operating range of the operating field may be understood as a preset area range in the embodiment of the present invention, then a request command is generated by the controller, and a request signal is generated and transmitted by the first antenna according to the request command, and the request signal may be received by the peer electronic device in the operating field, and after receiving the request signal, the peer electronic device may respond, that is, the peer electronic device may generate a response signal according to the received request signal, specifically, the peer electronic device may generate the response signal by load modulation, for example, by Amplitude Shift Keying (ASK), and then, sending the response signal to the transmitting terminal (i.e., the first antenna) of the request signal, after the first antenna receives the response signal, determining that the opposite-terminal electronic device capable of receiving the request signal exists within the preset area range, and determining the opposite-terminal electronic device sending the response signal as the second electronic device.

In the detection process, the first antenna processes the first information by, for example, modulation, encoding, encryption, etc. to generate a corresponding request signal, and after receiving the request signal, the second electronic device generally needs to analyze the request signal by, for example, demodulation, decoding, decryption, etc. to obtain the specific information content of the request signal, and in the process of generating the response signal according to the request signal, at least modulation, etc. is performed.

In addition, in the specific implementation process, there may be a plurality of peer electronic devices existing in the working field of the first antenna at the same time, and the collision avoidance algorithm listed in the first detection method may also be adopted to avoid the problems of channel contention and signal interference between the plurality of peer electronic devices as much as possible, which is not described herein again.

Optionally, in the embodiment of the present invention, the first detection duration is different from the second detection duration; the first detection duration is duration consumed by the first detection mode, and the second detection duration is duration consumed by the second detection mode.

That is, the detection duration consumed by the two detection methods may be different due to different specific processes of detection. For example, since the detection process of the first detection method is relatively simple, the first detection time duration may be shorter than the second detection time duration, and the detection efficiency is relatively high.

In addition, the second detection mode is more precise in detection process and higher in detection accuracy, and in the specific implementation process, which detection mode is specifically adopted can be specifically set according to the degree of the bias of the user on the detection efficiency and the detection accuracy.

Step 102: a target antenna is determined from M antennas of the first electronic device, M being an integer greater than 1.

That is to say, after determining second electronic equipment, in order to communicate with second electronic equipment with better communication quality and efficiency, first electronic equipment can select the target antenna from a plurality of antennas, and then communicates with second electronic equipment through the target antenna, can make full use of the characteristics that are provided with a plurality of antennas simultaneously in first electronic equipment like this, provides a high quality and efficient communication mode.

In a specific implementation process, the target antenna may be screened from the M antennas in the following manner:

optionally, in this embodiment of the present invention, determining the target antenna from the M antennas of the first electronic device specifically includes:

obtaining K feedback signals; the K feedback signals consist of the first feedback signal and at least one feedback signal, the at least one feedback signal respectively corresponds to part or all of the M-1 antennas except the first antenna, and K is an integer greater than 1;

and determining the target antenna from the M antennas according to the K feedback signals.

That is, after the second electronic device is detected within the preset area, in order to screen out the target antenna from the M antennas, the probe signals may be sent to the second electronic device through each antenna except the first antenna among the M antennas, and in order to ensure the accuracy of the determination result and reduce the difference, the signal strengths of the probe signals transmitted by all the antennas may be set to be the same, that is, the signal strength is the first signal strength regardless of which antenna transmits the probe signal.

Since the M antennas are disposed at different positions in the first electronic device, when a probe signal is transmitted to the second electronic device detected by the first antenna through another antenna except the first antenna, the second electronic device may not be within the predetermined area corresponding to the antenna, therefore, the detection signal transmitted by the antenna cannot be received, and naturally, the corresponding feedback signal cannot be generated according to the detection signal transmitted by the antenna, therefore, after the probe signal is transmitted to the second electronic device through each of the M antennas except the first antenna, including the first feedback signal, the first electronic device may obtain a total number of feedback signals that is equal to or less than M, that is, K in the embodiment of the present invention may be equal to or smaller than M, which is determined according to the position where each antenna is disposed in the electronic device and the specific preset area range.

Further, after obtaining the K feedback signals, a target antenna may be selected from the M antennas according to the K feedback signals. The specific manner of selection may be varied and two are listed below for illustration:

the first mode is as follows:

optionally, in this embodiment of the present invention, determining the target antenna from the M antennas according to the K feedback signals specifically may include:

determining K signal strengths corresponding to the K feedback signals;

After K feedback signals are obtained, it is naturally possible to determine K signal strengths corresponding to the K feedback signals and an antenna corresponding to each signal strength.

Because the feedback signal is used to indicate the signal strength of the probe signal received by the second electronic device, and generally, the stronger the signal strength is, the better the communication quality may be, if the signal strength exceeds a signal strength reference, the performance of the corresponding antenna may be better for the second electronic device, and naturally, the communication quality when communicating with the second electronic device may be better, so that the higher communication requirements of the first electronic device and the second electronic device can be met.

Then, in the embodiment of the present invention, the signal strengths of the K feedback signals may be filtered by setting a signal strength reference (i.e., a preset signal strength threshold), so as to obtain an antenna with better performance for the second electronic device, and the preset signal strength threshold may be determined comprehensively according to factors such as a specific communication mode performed by the first electronic device, a use loss condition of the first electronic device, and a requirement of user communication quality, which is not limited in the present invention.

For example, taking K as 4 as an example, the corresponding antennas may be a first antenna, a second antenna, a third antenna, and a fourth antenna, the corresponding signal strengths may be 10dBm, 4dBm, 6.8dBm, and 13.6dBm, respectively, and the preset signal strength threshold is 8dBm, it can be seen that 10dBm and 13.6dBm are both greater than 8dBm, which indicates that the antenna determined by the first method is two antennas, namely, the first antenna and the fourth antenna, i.e., the N value is 2.

Further, after the first antenna and the fourth antenna are determined in the first manner, which antenna is specifically determined as a target antenna, in a specific implementation process, in order to meet a quality requirement of communication, one of the two antennas may be selected as the target antenna, or in order to optimize the quality of communication, optionally, in an embodiment of the present invention, determining the target antenna from N antennas corresponding to the N signal strengths among the M antennas may specifically include:

That is to say, the antenna corresponding to the maximum signal strength value may be determined as the target antenna, so that it may be ensured that the first electronic device communicates with the second electronic device through the antenna with the optimal performance relative to the second electronic device when communicating with the second electronic device, and thus the best quality of communication may be ensured as much as possible.

The second mode is as follows:

Since the feedback Signal is used to indicate the Signal strength of the probe Signal Received by the second electronic device, that is, the feedback Signal can be understood as the Received Signal Strength Indication (RSSI) of the second electronic device, the K transmission distances corresponding to the K feedback signals can be determined according to the empirical conversion formula of the RRSI and the transmission distances, that is, since the change of the Signal strength of the probe Signal during transmission from the antenna to the second electronic device may be mainly caused by the transmission distances, the transmission distances can be approximately determined by the difference between the Signal strengths of the probe Signal and the feedback Signal, and the error of the result when the transmission distance is determined by the RRSI is relatively small, while the communication method in the embodiment of the present invention is just a short-distance communication method, so the error of the result determined by this method is relatively small, the accuracy is high.

That is, after K feedback signals are obtained, K transmission distances corresponding to the K feedback signals and an antenna corresponding to each of the K signal strengths can be determined.

Generally, the shorter the transmission distance, the smaller the loss, the higher the quality of the communication, and the shorter the signal transmission time due to the shorter distance, the higher the speed and efficiency of the communication. If the transmission distance is smaller than the preset distance threshold, it is indicated that the performance of the corresponding antenna is better for the second electronic device, and the communication quality is better when the antenna is naturally communicated with the second electronic device, so that the higher communication requirement of the first electronic device can be met. In addition, the preset distance threshold may be determined comprehensively according to factors such as a specific communication mode performed by the first electronic device, a usage loss condition of the first electronic device, and a requirement of user communication quality, and the present invention is not limited specifically.

For example, taking K as 4 as an example, the corresponding antennas may be a first antenna, a second antenna, a third antenna and a fourth antenna, the corresponding transmission distances may be 6cm, 17cm, 3cm and 9cm, and the preset distance threshold is 10cm, it can be seen that 6cm, 3cm and 9cm are all less than 10cm, it indicates that the antennas determined by the second way are three antennas, namely, the first antenna, the third antenna and the fourth antenna, and that N is 3.

Further, after the first antenna, the third antenna, and the fourth antenna are determined in the second manner, specifically, which antenna is determined as the target antenna, in a specific implementation process, one of the three antennas may be selected as the target antenna, or in order to maximize a communication rate, optionally, in an embodiment of the present invention, the determining the target antenna from N antennas corresponding to the N transmission distances among the M antennas may specifically include:

That is to say, the antenna corresponding to the minimum transmission distance value may be determined as the target antenna, so that it may be ensured that the first electronic device communicates with the second electronic device by using the antenna with the highest transmission efficiency compared to the second electronic device when communicating with the second electronic device, and thus, the communication efficiency may be improved on the premise of ensuring the better communication quality as much as possible.

In addition, the applicant just lists two ways for description, and it should be clear to those skilled in the art that the present application is only exemplified by the above two ways, and other more possible ways are not listed, and all methods capable of determining the target antenna from M antennas according to the K feedback signals are within the protection scope of the present application.

Optionally, in this embodiment of the present invention, after determining K transmission distances corresponding to the K feedback signals, the method may further include:

That is to say, after K transmission distances corresponding to K feedback signals and K antennas corresponding to the K feedback signals are obtained, the first electronic device can determine the accurate position of the second electronic device in the physical space by setting the K transmission distances and the corresponding antennas in the first electronic device, and can perform accurate positioning on the second electronic device, so that the relative position relationship between the second electronic device and the first electronic device can be determined.

The specific use of which of the K distances and the corresponding antenna positions to determine the spatial position of the second electronic device may be determined by the specific positioning method to be taken. In a specific implementation process, for example, a dual-distance positioning mode, a triple-distance positioning mode, a multi-distance positioning mode, or other positioning modes may be adopted to determine the spatial position of the second electronic device, which positioning mode is specifically adopted may be comprehensively considered according to the positioning accuracy, the positioning duration requirement, or other factors, and the present invention is not limited specifically.

Optionally, in this embodiment of the present invention, after determining the spatial position of the second electronic device, the method may further include:

After the spatial position of the second electronic device is determined, the first electronic device can approximately determine the specific position of a user using or carrying the second electronic device, and further can determine the relative position between the user and the display unit of the first electronic device, so that the user can also see corresponding display content nearby through the display unit of the first electronic device or can conveniently operate the display unit, the first electronic device can determine a corresponding first display area for the user on the display unit, and thus the user can directly see the display content on the first display area or directly operate in the first display area, so that information interaction is rapidly and directly performed with the first electronic device, and the use experience of the user is improved.

And the first display area can be used for displaying information related to the second electronic device, because the second electronic device performs energy interaction with the target antenna in the first electronic device in a short-distance communication mode to complete information interaction, then, the second electronic device can directly send some stored information to the first display area for displaying, or can directly project the display interface of the second electronic device into the first display area, so that a user can conveniently and directly view and share the information. In the embodiment of the invention, the first electronic device can be an electronic device with a larger display unit, and the display unit can have a multi-touch function, so that multiple users can watch or operate the first electronic device conveniently at the same time, especially for some large-screen game devices, the users can share information in real time, and the use experience of the users is improved.

For example, referring to fig. 2, taking the first electronic device as a large-screen game device and the second electronic device as a mobile phone as an example, assuming that the large-screen game device determines that the spatial position of the mobile phone is located at the upper left corner of the mobile phone, the large-screen game device may approximately determine that a user exists near the edge of the upper left corner of the mobile phone, and then may provide a first display area 200 for the user of the second electronic device in the upper left corner area of the display unit, so that the user may conveniently watch or operate nearby, and the usage habit of the user is matched as much as possible, thereby enhancing the usage experience of the user. In a specific implementation process, a specific form of the first display area 200 may not be limited, and fig. 2 illustrates an example in which the first display area 200 is rectangular.

Step 103: communicating with the second electronic device through the target antenna.

That is, the first electronic device communicates with the second electronic device through the determined target antenna.

Referring to fig. 3, based on the same inventive concept, an embodiment of the present invention provides an electronic device, including:
