Embodiments for Carrying Out the Invention

[0013] Hereinafter, embodiments of the present disclosure will be described in detail with appropriate reference to the drawings. However, detailed descriptions that are more than necessary may be omitted. For example, detailed descriptions of well-known matters and duplicate descriptions of substantially the same configurations may be omitted. This is to avoid making the following description unnecessarily redundant and to facilitate the understanding of those skilled in the art. Note that the attached drawings and the following description are provided to enable those skilled in the art to fully understand the present disclosure, and are not intended to limit the subject matter described in the claims.

[0014] (This embodiment) FIG. 1 is a conceptual diagram for explaining the wireless connection between an AP (Access Point) 10 and a STA (Station) 20. Note that FIG. 1 is a plan view of the AP 10 and the STA 20 as viewed from above.

[0015] As shown in FIG. 1, the communication system 1 includes an AP 10, an STA 20, and a smartphone 30. Note that the AP 10 may be read as the first wireless device, and the STA 20 may be read as the second wireless device. Also, when not distinguishing between the first wireless device and the second wireless device, it may simply be referred to as a wireless device. Further, the smartphone 30 may be read as an information processing device.

[0016] The AP 10 and the STA 20 are capable of millimeter-wave communication, which is an example of wireless communication, and have a beamforming function. That is, the AP 10 and the STA 20 can set a directional beam for radio waves transmitted or received by a plurality of antenna elements 44. Note that the wavelength band of the radio waves used by the AP 10 and the STA 20 for wireless communication is not limited to the millimeter-wave band and may be any wavelength band.

[0017] Conventionally, when wirelessly connecting (that is, establishing a wireless link) the AP 10 and the STA 20 installed at positions separated from each other, the following procedures (S1) to (S2) are performed. (S1) The AP 10 transmits a beacon with a directional beam 100. (S2) The STA 20 uses a pseudo-omnipattern 110 to receive the beacon transmitted by the directional beam 100 of the AP 10 and wirelessly connects to the AP 10.

[0018] The pseudo-omnipattern 110 has a wider reception range (reception angle) than the directional beam, but has a lower reception gain. Therefore, there may be a case where communication cannot be established because the sum of the transmission gain of the AP 10, the reception gain of the STA 20, and the propagation loss (where the propagation loss is a negative value) between the AP 10 and the STA 20 does not exceed the reception sensitivity of the STA 20.

[0019] On one hand, by setting a directional beam 200 with a narrow reception range (reception angle) for STA20, the reception gain of STA20 increases. Therefore, STA20 can be wirelessly connected to an AP10 that is farther away. However, it is difficult to align the reception range of the directional beam 200 of STA20 with the transmission range of the directional beam 100 of AP10 so that STA20 can receive the beacon transmitted by AP10 with the directional beam 100.

[0020] Therefore, in the following, a communication system, a wireless connection method, and a wireless device that can easily establish a wireless connection between AP10 and STA20 will be described, not only when the distance between AP10 and STA20 is short, but also when the distance between AP10 and STA20 is long.

[0021] <Configuration of the communication system> FIG. 2 is a block diagram showing a configuration example of a communication system 1 according to the present embodiment. FIG. 3 is a block diagram showing a configuration example of a wireless module 24 according to the present embodiment.

[0022] AP10 (first wireless device) includes a processor 11, a memory 12, a connection interface 13, and a wireless module 14. STA20 (second wireless device) includes a processor 21, a memory 22, a connection interface 23, and a wireless module 24. As shown in FIG. 2, AP10 and STA20 may have the same configuration. Therefore, in the description of FIGS. 2 and 3, the components of STA20 will be described, and the description of the components of AP10 will be omitted.

[0023] The processor 21 is configured using, for example, a CPU (Central Processing Unit), an MPU (Micro Processing Unit), a DSP (Digital Signal Processor), or an FPGA (Field Programmable Gate Array). The processor 21 performs control processing for overall coordination of the operations of each part 22 to 24 of STA20.

[0024] The memory 22 may include a ROM (Read-Only Memory), a RAM (Random Access Memory), a flash memory, etc., and holds various programs and various data executed by the processor 21. For example, the memory 22 holds the conversion information 70 shown in FIG. 5.

[0025] The connection interface 23 is an interface for connecting an external device such as the smartphone 30. The connection interface 23 includes a communication circuit corresponding to wired communication or wireless communication. Examples of the connection interface 23 for wired communication include a USB (Universal Serial Bus) interface. Examples of the connection interface 23 for wireless communication include an interface for Wi-Fi (registered trademark) communication or an interface for Bluetooth (registered trademark) communication.

[0026] As shown in FIG. 3, the wireless module 24 includes a wireless control circuit 41 that processes wireless signals, a plurality of gain adjustment circuits 42, a plurality of phase adjustment circuits 43, and a plurality of antenna elements 44. The plurality of antenna elements 44 may be read as an array antenna.

[0027] As shown in FIG. 3, one gain adjustment circuit 42 and one phase adjustment circuit 43 are associated with one antenna element 44. The wireless control circuit 41 can realize directivity beams 200 of various patterns by adjusting the gain value and phase value of the signal by the gain adjustment circuit 42 and the phase adjustment circuit 43 associated with each antenna element 44, respectively. For example, the wireless control circuit 41 can narrow the reception range (reception angle) of the directivity beam 200 to increase the reception gain, or widen the reception range (reception angle) of the directivity beam 200 to lower the reception gain. In addition, the wireless control circuit 41 may be able to change the direction of the directivity beam 200 up, down, left, or right.

[0028] A smartphone 30, which is an example of an information processing device, includes a processor 31, a memory 32, a connection interface 33, a camera 34, a display device 35, and an input device 36.

[0029] The processor 31 is configured using, for example, a CPU, MPU, DSP, or FPGA. The processor 31 performs control processing for overall coordination of the operations of each part 32-36 of the smartphone 30.

[0030] The memory 32 may include a ROM, RAM, flash memory, etc., and holds various programs and various data executed by the processor 31. For example, the memory 32 holds an adjustment UI program described later.

[0031] The connection interface 33 is an interface for connecting the smartphone 30 to the STA 20. The connection interface 33 includes a communication circuit corresponding to wired communication or wireless communication. Examples of the connection interface 33 for wired communication include a USB interface. Examples of the connection interface 33 for wireless communication include a Wi-Fi communication interface or a Bluetooth communication interface.

[0032] The camera 34 is configured to include a lens and an imaging element, and captures an image. The camera 34 may be provided with a zoom mechanism. Note that the camera 34 may be read as an imaging device. Further, instead of or in addition to the zoom mechanism, the processor 31 may be provided with a digital zoom processing function.

[0033] The display device 35 is a device that displays an image. The display device 35 is, for example, a liquid crystal display or an organic EL display.

[0034] The input device 36 is a device that detects an input operation from an operator, which is an example of a user. The input device 36 is, for example, a touch panel, button, switch, bar, keyboard, mouse, and / or microphone, etc.

[0035] <Antenna pattern information> FIG. 4 shows an example of the antenna pattern information 60 according to the present embodiment.

[0036] The antenna pattern information 60 is information indicating the correspondence between the combination of the gain value and the phase value of each antenna element 44 and the sector ID. The antenna pattern information 60 may be held in the radio control circuit 41 of the radio module 24. However, the antenna pattern information 60 may be held in the memory 22.

[0037] In FIG. 4, “disable” indicates that the corresponding antenna element 44 is not used, and “A” m,n ” (m, n are integers of 1 or more) indicates the gain value set in the gain adjustment circuit 42 corresponding to the corresponding antenna element 44, and “θ” m,n ” indicates the phase value set in the phase adjustment circuit 43 corresponding to the corresponding antenna element 44.

[0038] The antenna pattern information 60 may be set such that at least one of the reception range (reception angle) and the reception gain of the directive beam 200 is different when the sector ID is different.

[0039] For example, in the antenna pattern information 60 shown in FIG. 4, the combination of the gain value and the phase value of each antenna element 44 associated with the sector ID “0xFF” has the widest reception range (reception angle) of the directive beam 200 and the lowest reception gain, and in the order of the sector ID “0xFE”, the sector ID “0xFD”, and the sector ID “0xFC”, the reception range of the directive beam 200 is set to be narrow and the reception gain is set to be high.

[0040] <Conversion information> FIG. 5 shows an example of the conversion information 70 according to the present embodiment.

[0041] The conversion information 70 is information indicating the correspondence between the imaging magnification of the camera 34 and the sector ID. The conversion information 70 may be held in the memory 22 of the STA 20.

[0042] The conversion information 70 may be set so as to be associated with a sector ID in which the reception range (reception angle) of the directional beam 200 is narrow and the reception gain is high as the imaging magnification of the camera 34 is larger. In other words, the conversion information 70 may be set so as to be associated with a sector ID in which the reception range (reception angle) of the directional beam 200 is wide and the reception gain is low as the imaging magnification of the camera 34 is smaller.

[0043] For example, in the conversion information 70 shown in FIG. 5, the sector ID "0xFF" in which the reception range (reception angle) of the directional beam 200 is the widest and the reception gain is the lowest is associated with the imaging magnification "1x" of the camera 34, and the sector ID "0xFE", the sector ID "0xFD", and the sector ID "0xFC" are associated with the imaging magnifications of the camera 34 being "2x", "4x", and "8x" in this order so that the reception range of the directional beam 200 becomes narrow and the reception gain becomes high.

[0044] <Wireless connection method> FIG. 6 shows a sequence chart showing an example of the wireless connection method according to the present embodiment. FIG. 7 is a diagram showing an example of mounting the smartphone 30 on the STA20 according to the present embodiment. FIG. 8 is a diagram showing an example of the adjustment UI image 300 displayed on the display device 35 of the smartphone 30 according to the present embodiment.

[0045] As shown in FIG. 7, the STA20 is fixed at a predetermined height position of the pole 26 extending in the height direction, and the direction F1 of the directional beam 200 of the STA20 may be in the horizontal direction. When the operator fixes the STA20 to the pole 26, the operator may adjust the direction F1 of the directional beam 200 of the STA20 to face the direction of the AP10. For example, the operator horizontally rotates (rotates about the axis) the STA20 around the axis of the pole 26 so that the STA20 faces the direction of the AP10, and fixes the STA20 to the pole 26.

[0046] The operator attaches the smartphone 30 to the adapter 25 of the STA20 (step S11). As shown in FIG. 7, when the smartphone 30 is attached, the adapter is configured such that the camera 34 of the smartphone 30 faces the direction F2 in which the radio wave reception direction by the array antenna of the STA20 is imaged (i.e., the direction F1 of the directional beam 200). For example, as shown in FIG. 7, the adapter 25 may be configured to allow the smartphone 30 to be slid on from above for attachment.

[0047] The operator activates the adjustment UI program of the smartphone 30 (step S12). As a result, as shown in FIG. 8, an adjustment UI image 300 is displayed on the display device 35 of the smartphone 30. As shown in FIG. 8, the adjustment UI image 300 may display an imaging image 350 of the camera 34, a magnification operation bar 351 for adjusting the imaging magnification of the camera 34, a magnification image 352 indicating the imaging magnification of the camera 34, a completion button 353 for completing the adjustment of the imaging magnification, and a center mark 354 indicating the center position of the imaging image. Note that in this embodiment, an example is shown in which all the components of the adjustment UI program are recorded and activated in the smartphone 30, but the scope of the present disclosure is not limited to this. For example, part or all of the adjustment UI program may be executed in another information processing device. Further, the smartphone 30 may transmit necessary information such as the imaging magnification to the STA20 via other information processing.

[0048] The operator performs an operation to change the display of the imaging image 350. For example, the operator operates the magnification operation bar 351 to change (e.g., enlarge or reduce) the imaging magnification of the camera 34 (step S13). Note that this change in the imaging magnification may be a change that physically adjusts the lens position of the camera 34 to optically enlarge or reduce the imaging image, or a change that digitally enlarges or reduces the imaging image displayed on the display device 35.

[0049] The smartphone 30 transmits information indicating the changed imaging magnification of the camera 34 to the STA20 (step S14).

[0050] The processor 21 of STA20 refers to the conversion information 70 and specifies the sector ID corresponding to the imaging magnification transmitted from the smartphone 30 (step S15).

[0051] The processor 21 of STA20 transmits the specified sector ID to the wireless module 24 (step S16).

[0052] The wireless control circuit 41 of the wireless module 24 receives the sector ID transmitted from the processor 21 in step S16, and refers to the antenna pattern information 60 to specify the antenna pattern corresponding to the received sector ID (step S17). As described above, the antenna pattern may be a combination of the gain value and phase value of each antenna element 44.

[0053] The wireless control circuit 41 of the wireless module 24 changes the reception range (reception angle θ) and reception gain d of the directional beam 200 as shown in FIG. 8 by setting the gain value and phase value of each antenna element 44 indicated by the specified antenna pattern to the gain adjustment circuit 42 and phase adjustment circuit 43 of each antenna element 44, respectively (step S18).

[0054] The processes from step S14 to step S18 may be repeatedly executed each time the operator changes the imaging magnification of the camera 34 in step S13.

[0055] For example, when the operator sets the imaging magnification to "1x" as shown in Fig. 8(a) in step S13, the STA20 sets a directional beam 200A with a relatively wide reception range (reception angle θ) and a low reception gain d in steps S17 and S18. For example, when the operator sets the imaging magnification to "2x" as shown in Fig. 8(b) in step S13, the STA20 sets a directional beam 200B with a narrower reception range (reception angle θ) and a higher reception gain d than when the imaging magnification is "1x" in steps S17 and S18. For example, when the operator sets the imaging magnification to "8x" as shown in Fig. 8(c) in step S13, the STA20 sets a directional beam 200C with a narrower reception range (reception angle θ) and a higher reception gain d than when the imaging magnification is "2x" in steps S17 and S18.

[0056] In this way, the operator can easily adjust the reception range (reception angle θ) and reception gain d of the directional beam 200 of the STA20 by adjusting the imaging magnification of the camera 34 of the smartphone 30. For example, the operator can gradually increase the reception gain d in the direction of the AP10 in the directional beam 200 of the STA20 by gradually enlarging the imaging magnification and operating the smartphone 30 so that the AP10 can be visually recognized in the captured image 350. Thereby, the operator can make the STA20 detect the AP10 located at a distance that was difficult to detect with the conventional pseudo-omnipattern 110 with a simple operation. That is, the operation of wirelessly connecting the STA20 to the AP10 located farther away can be performed easily and efficiently.

[0057] Returning to the description of Fig. 6. When the wireless connection between the STA20 and the AP10 is completed, the operator selects (for example, taps) the completion button 353 through the input device 36 (step S19).

[0058] When the smartphone 30 detects the selection (for example, tap) of the completion button 353, it sends a completion notification to the STA20 (step S20).

[0059] When the processor 21 of the STA20 receives the completion notice transmitted from the smartphone 30, it saves the current sector ID in the memory 22 (step S21). That is, the STA20 determines the antenna pattern corresponding to the current sector ID as the directive beam 200 for wireless communication with the AP10. Then, the processor 21 of the STA20 ends this process.

[0060] Through the above processing, the operator can easily adjust the reception range (reception angle θ) and reception gain d of the directive beam 200 of the STA20 by adjusting the imaging magnification of the camera 34 of the smartphone 30 connected to the STA20, and can perform the operation of wirelessly connecting the STA20 to the remotely located AP10 simply and efficiently.

[0061] Note that the information indicating the imaging magnification of the camera 34 transmitted from the smartphone 30 to the STA20 in step S14 of FIG. 6 is an example of the information generated by the operation when the user changes the display of the imaging image 350. For example, the information generated by the operation may include information indicating the change in the display of the imaging image 350. For example, the information generated by the operation may include information indicating the degree of change in the radio wave reception range and reception gain. For example, the information generated by the operation may include the sector ID corresponding to the imaging magnification. For example, the information generated by the operation may include parameters (for example, the gain value and phase value of each antenna element) for setting the directive beam corresponding to the imaging magnification.

[0062] (Summary of the present disclosure) The content of the present disclosure can be expressed as follows.

[0063] <Expression 1> The communication system 1 includes a wireless device (e.g., STA20) that wirelessly connects to other wireless devices (e.g., AP10), and an information processing device (e.g., smartphone 30) connected to the wireless device. The information processing device displays an imaging image 350 in which the reception direction of the radio wave of the wireless device is imaged. When an operation to change the display of the imaging image 350 is performed by a user (e.g., an operator), the information generated by the operation is transmitted to the wireless device, and the wireless device changes the reception range of the radio wave based on the information received from the information processing device. Thus, the user can easily change the reception range of the radio wave of the wireless device by performing an operation to change the display of the imaging image 350. Therefore, the user can efficiently perform the work of adjusting the reception range of the radio wave of the wireless device so as to receive the beacon transmitted from other wireless devices and wirelessly connecting the wireless device to other wireless devices.

[0064] <Expression 2> In the communication system 1 described in Expression 1, the information generated by the operation may be information indicating a change in the display of the imaging image. Thus, the wireless device can change the reception range of the radio wave based on the information indicating a change in the display of the imaging image received from the information processing device.

[0065] <Expression 3> In the communication system 1 described in Expression 1, the information generated by the operation is information indicating the degree of changing the reception range and reception gain of the radio wave, and the wireless device may change the reception range and reception gain of the radio wave based on the information indicating the degree of changing the reception range and reception gain of the radio wave received from the information processing device. Thus, the wireless device can change the reception range and reception gain of the radio wave based on the information indicating the degree of changing the reception range and reception gain of the radio wave received from the information processing device.

[0066] <Expression 4> In the communication system 1 described in Expression 2, the operation for changing the display of the captured image 350 is an operation for changing the zoom ratio of the captured image 350, the information indicating the change in the display of the captured image 350 is information indicating the zoom ratio, and the wireless device may change the radio wave reception range and reception gain based on the information indicating the zoom ratio received from the information processing device. Thus, the user can easily change the radio wave reception range and reception gain of the wireless device by operating to change the zoom ratio of the captured image 350 of the information processing device. Therefore, the user can efficiently perform the work of adjusting the radio wave reception range and reception gain of the wireless device through the information processing device so as to receive the beacon transmitted from another wireless device and wirelessly connect the wireless device to another wireless device.

[0067] <Expression 5> In the communication system 1 described in Expression 4, the reception gain of radio waves when the zoom ratio is the first magnification may be larger than the reception gain of radio waves when the zoom ratio is a second magnification smaller than the first magnification. Thus, the user can increase the reception gain of the radio waves of the wireless device by operating to increase the zoom ratio.

[0068] <Expression 6> In the communication system 1 described in Expression 4, the wireless device has conversion information 70 that associates a zoom ratio with a sector ID indicating an antenna pattern with a different radio wave reception range, and based on the conversion information 70, identifies the sector ID corresponding to the zoom ratio received from the information processing device, and may change the radio wave reception range based on the antenna pattern indicated by the identified sector ID. Thus, the wireless device can identify the sector ID indicating an appropriate antenna pattern for the zoom ratio received from the information processing device. That is, the wireless device can set an appropriate radio wave reception range for the zoom ratio received from the information processing device.

[0069] <Expression 7> In a wireless connection method for wirelessly connecting a wireless device (e.g., STA20) to another wireless device (e.g., AP10), an information processing device (e.g., smartphone 30) displays a captured image 350 in which the reception direction of the radio wave of the wireless device is captured. When an operation to change the display of the captured image 350 is performed by the user, the information generated by the operation is transmitted to the wireless device. The wireless device changes the radio wave reception range based on the information received from the information processing device and performs a wireless connection with the other wireless device. Thereby, the user can easily change the radio wave reception range of the wireless device by performing an operation to change the display of the captured image 350 of the information processing device. Therefore, the user can simply and efficiently perform the work of adjusting the radio wave reception range of the wireless device so as to receive the beacon transmitted from the other wireless device and wirelessly connecting the wireless device to the other wireless device.

[0070] <Expression 8> A wireless device (e.g., STA20) that performs a wireless connection with another wireless device (e.g., AP10) includes a plurality of antenna elements 40 and a processor 21 that changes the radio wave reception range based on the information received when the information generated by an operation to change the display of a captured image 350 in which the reception direction of the radio wave received by the antenna element 44 from a predetermined information processing device (e.g., smartphone 30) is captured is received. Thereby, the wireless device can receive the information generated by the operation to change the display of the captured image from the information processing device and change the radio wave reception range based on the received information. Therefore, the user can simply and efficiently perform the work of adjusting the radio wave reception range of the wireless device so as to receive the beacon transmitted from the other wireless device through the information processing device and wirelessly connecting the wireless device to the other wireless device.

It is obvious that those skilled in the art can conceive of various modification examples, correction examples, substitution examples, addition examples, deletion examples, and equivalent examples within the scope described in the claims, and it is understood that these also belong to the technical scope of the present disclosure.
