Description

Technical Field

[0001] This invention relates to a wireless AV transmission system that provides a method for setting the antenna pointing direction. Background Technology

[0002] In recent years, due to the dramatic increase in network traffic caused by electronic devices, fifth-generation mobile communication (5G) technology, which uses ultra-high frequency signals, has been developed. For example, millimeter waves (mmWave), with a wavelength of millimeters, can be applied to fifth-generation mobile communication.

[0003] To reduce path loss and increase transmission distance of radio waves in the mmWave band, technologies explored in 5G communication systems include beamforming, massive MIMO, full dimensional MIMO (FD-MIMO), array antenna, analog beamforming, and large scale antenna.

[0004] For example, in 5G wireless communication systems, when transmitting and receiving signals in the mmWave (above 6 GHz) band, beamforming technology based on multiple antennas can be used to overcome high signal attenuation. Beamforming is a method of maximizing signal transmission and reception gain in the desired direction by adjusting the phase of each antenna. To this end, according to various embodiments, electronic devices can use a beambook composed of multiple beams, which are pre-designed to point in different directions from each other. When transmitting and receiving signals, the electronic device can dynamically select the most suitable beam from the multiple beams constituting the beambook for beamforming based on the current wireless channel conditions through beam management.

[0005] In existing technologies, beam paths are set on the PCP / NPCP antennas of electronic devices according to configuration conditions. Although beam tracking (vertical / horizontal) can be achieved through the antenna's own beamforming, problems such as transmission and reception interruption or image quality degradation can occur due to the lack of avoidance paths when temporary faults occur between PCP / NPCP antennas and the signal quality of beam avoidance deteriorates. Summary of the Invention

[0010] According to an embodiment, the step of performing beam scanning between the first antenna and the second antenna includes: setting the position of at least one of the first antennas within the adjustment range of the horizontal rotation direction and the pitch direction of the first antenna; and performing at least one beam scan based on the set position of the first antenna.

[0011] According to an embodiment, the step of storing beam pairs with signal quality above a reference value among the stored plurality of beam pairs as candidate beam paths includes: determining whether there is a beam path that satisfies a preset signal quality among the plurality of beam pairs stored according to the position of the first antenna; and storing the beam path if there is a beam path that satisfies the signal quality.

[0012] According to an embodiment, the step of setting the direction of the first antenna to include a plurality of candidate beam paths within the beamforming region of the first antenna includes: confirming whether the directions of the plurality of candidate beam paths are separated by a value preset based on a beam table to set an effective beam path; calculating the horizontal rotation direction and pitch direction within the beam control range of the first antenna in the vertical and horizontal directions, taking into account the number of effective beam paths and signal quality; and setting the direction of the first antenna based on the calculated horizontal rotation direction and pitch direction.

[0013] According to an embodiment, the step of providing antenna pointing direction setting guidance corresponding to the set direction of the first antenna includes: displaying clockwise and counterclockwise directions and rotation amount according to the calculated horizontal rotation direction; displaying vertical direction and rotation amount according to the calculated pitch direction; and displaying whether alignment occurs as the antenna direction changes.

[0028] The detailed description above should not be construed as limiting in all respects, but rather as exemplary. The scope of the invention should be determined by a reasonable interpretation of the appended claims, and all modifications within the equivalent scope of the invention are included within the scope of the invention.

[0029] Figure 1 This is an overall block diagram of a wireless AV transmission system according to one of the plurality of embodiments of the present invention. Figure 2 This is a diagram illustrating a first terminal of a wireless AV transmission system according to one embodiment of a plurality of embodiments of the present invention.

[0030] Reference Figure 1 and Figure 2 A wireless AV transmission system 1000 according to an embodiment of the present invention may include a first terminal 100 and a second terminal 200.

[0031] The first terminal 100 may include a first antenna 110, a memory unit 120, an output unit 130, and a control unit 140.

[0032] The first terminal 100 and the second terminal 200 can employ phased array antennas (PCP, NPCP) using the millimeter-wave (mmWave) frequency band. The first terminal 110 can generate a beam path for communication with the second antenna 210 of the second terminal 200 via beam pairs. In this case, the first antenna 110 can be a PCP antenna as a phased array antenna, and the second antenna 210 can be an NPCP antenna. The first antenna 110 can include a transceiver unit 111 for transmitting and receiving signals.

[0033] The first antenna 110 can perform beam tracking in the vertical and horizontal directions through its own beamforming. That is, the first antenna can generate a beam path for communication within the beam coverage area through beamforming. The following... Figure 2 More specific embodiments relating to this are described in more detail below.

[0034] In addition, the first antenna 110 can change its pointing direction in accordance with horizontal rotation and pitch adjustment.

[0035] The memory unit 120 can store a beam book, which stores the inter-beam angles set by the antenna feed signal strength and phase. In this case, the beam book can include the beam book of the first terminal and the beam book of the second terminal. Hereinafter, Figure 3 More specific embodiments relating to this are described in more detail below.

[0036] The output unit 130 can guide the user to adjust the horizontal rotation and pitch of the first antenna 110 of the first terminal 100 via at least one of a screen, voice, or image. Hereinafter, in Figure 7 More specific embodiments relating to this are described in more detail below.

[0037] In addition, the output unit 130 can guide the user to adjust the horizontal rotation and pitch of the second antenna 210 of the second terminal 200 through at least one of the screen, voice, and image.

[0038] The control unit 140 can determine the signal quality and beam direction of a plurality of beam pairs of the first terminal antenna 110 and the second antenna 210. At this time, the signal quality may include at least one of throughput (T-put), signal to noise ratio (SNR), and received signal strength indicator (RSSI).

[0039] The control unit 140 can confirm whether at least one beam pair with optimal characteristics (compression rate, transmission rate) among the plurality of beam pairs of the first antenna 110 and the second antenna 210 is an isolation block or higher as determined in the beam book, and whether the signal quality is above the reference value. Then, the control unit 140 can store the confirmed beam pair information in the memory unit 120.

[0040] The control unit 140 can repeatedly confirm the signal quality at at least one location corresponding to the coverage area of ​​the first antenna 110.

[0041] After confirming the signal quality by position, the control unit 140 can set the antenna pointing direction of the first antenna 110.

[0042] After setting the antenna pointing direction, the control unit 140 can output antenna pointing direction setting guidance through the output unit 130.

[0043] Next, the instructions will explain in detail the antenna pointing direction setting.

[0044] First, according to an embodiment of the present invention, the manual setting of the antenna direction will be explained. This is achieved by the relationship between the first terminal 100 and the second terminal 200.

[0045] For example, the first terminal 100 can use at least one of the following methods—screen, voice, or image—to guide the horizontal rotation and pitch directions of the first antenna 110 on the screen. The user can then set the antenna direction based on this guidance.

[0046] Then, the first terminal 100 can calculate the ID and signal quality of the main candidate beams in the beam pair generated by beam scanning through the first antenna 110 and the second antenna 210 in the set antenna direction. At this time, the beam ID represents the beam direction set based on the beam table.

[0047] In addition, the first terminal 100 can store the beam direction and signal quality of effective beams with signal quality above the reference value.

[0048] If the first terminal 100 completes the storage of beam direction and signal quality based on the antenna direction, the beam direction and signal quality can be repeatedly stored by changing the horizontal rotation direction and the pitch direction of the first antenna 110.

[0049] If the first terminal 100 confirms the beam direction and signal quality of the first antenna 110 in the overall or partial horizontal rotation and elevation directions, it can calculate the optimal horizontal rotation and elevation directions by considering the effective number of beams and signal quality within the beamsteering range of the first antenna 110 in the vertical and horizontal directions, and provide the user with antenna pointing direction setting guidance. At this time, the first terminal 100 can set the horizontal rotation and elevation directions in different intervals according to the beamsteering range.

[0050] When the first terminal 100 sets the antenna direction based on the antenna direction setting guide, it can confirm the effective beam level (signal quality, beam ID spacing) and complete the setting.

[0051] Afterwards, the first terminal 100 can set the optimal beam direction by making fine adjustments as needed.

[0052] Second, according to an embodiment of the present invention, the automatic setting of antenna pointing will be explained. This is achieved by the relationship between the first terminal 100 and the second terminal 200.

[0053] The first terminal 100 can calculate the ID and signal quality of the main candidate beams in the beam pair of the first antenna 110 and the second antenna 210 at a pre-set initial position. At this time, the beam ID represents the beam direction set based on the beam table.

[0054] In addition, the first terminal 100 can store the beam direction and signal quality of effective beams with signal quality above the reference value.

[0055] If the first terminal completes the storage of beam direction and signal quality based on the antenna direction, the beam direction and signal quality can be repeatedly stored by changing the horizontal rotation direction and the elevation direction of the antenna.

[0056] If the first terminal 100 confirms the beam direction and signal quality of the antenna's overall or partial horizontal rotation and elevation directions, it can calculate the horizontal rotation and elevation directions by considering the effective beam count and signal quality within the antenna's vertical and horizontal beam control range, and provide the user with antenna pointing direction setting guidance. At this time, the first terminal 100 can set the horizontal rotation and elevation directions according to different intervals within the beam control range.

[0057] When the first terminal 100 sets the antenna direction according to the guide, it can confirm the effective beam level (signal quality, beam ID spacing) and complete the setting.

[0058] Afterwards, the first terminal 100 can set the optimal beam direction by making fine adjustments as needed.

[0059] Figure 3 This is a diagram illustrating a beam table of a wireless AV transmission system according to one embodiment of a plurality of embodiments of the present invention.

[0060] like Figure 3 As shown, the beam table can include inter-beam angles using antenna feed signal strength and phase. Furthermore, the beam table can include candidate beam IDs based on horizontal rotation and elevation values ​​for the antenna orientation.

[0061] like Figure 3 As shown in (a), the beam table of the first antenna 110 can cover a total of 90 degrees from -45 degrees to +45 degrees, corresponding to the coverage area of ​​the horizontal rotation direction of the first terminal 100. The horizontal rotation direction of the antenna can be set to -45 degrees, -30 degrees, -15 degrees, 0 degrees, 15 degrees, 30 degrees, and 45 degrees.

[0062] Furthermore, the antenna can cover a total area of ​​90 degrees from -45 degrees to +45 degrees, corresponding to the coverage area of ​​the first terminal 100 in the elevation direction. The antenna elevation direction can be set to -45 degrees, -30 degrees, -15 degrees, 0 degrees, 15 degrees, 30 degrees, and 45 degrees.

[0063] The beam table of the first antenna 110 can combine the horizontal rotation direction and the elevation direction, and set the ID from 0 to 54.

[0064] like Figure 3 As shown in (b), the beam table of the second antenna 210 can cover a total area of ​​180 degrees from -90 degrees to +90 degrees, corresponding to the coverage area of ​​the horizontal rotation direction of the second terminal 200. The horizontal rotation direction of the antenna can be set to -90 degrees, -64 degrees, -56 degrees, -48 degrees, -40 degrees, -32 degrees, -24 degrees, 16 degrees, 8 degrees, 0 degrees, +8 degrees, +16 degrees, +24 degrees, +32 degrees, +40 degrees, +48 degrees, +56 degrees, +64 degrees, and +90 degrees.

[0065] Furthermore, the coverage area corresponding to the elevation direction of the second terminal 200 covers a total area of ​​120 degrees from -90 degrees to +30 degrees. The antenna elevation direction can then be set to -90 degrees, -30 degrees, 0 degrees, or +30 degrees.

[0066] The beam table of the second antenna 210 can be set to an ID of 0 to 57 corresponding to the combination of horizontal rotation direction and elevation direction.

[0067] Figure 4 This is a diagram illustrating the communication status of a single path in a wireless AV transmission system of one embodiment of the plurality of embodiments of the present invention.

[0068] Reference Figure 4 The wireless AV transmission system can set the main path 500 through the antenna pointing direction 300 and the beamforming area 400. The antenna pointing direction 300 and the beamforming area 400 are set according to the beam pair between the first terminal 100 and the second terminal 200.

[0069] According to an embodiment, the main path can be based on a beam table to pair beam 27 of the first terminal 100 and beam 28 of the second terminal 200 and establish communication. At this time, the horizontal rotation and elevation values ​​of the antenna pointing direction of the first terminal 100 are 0 degrees, and the horizontal rotation and elevation values ​​of the antenna of the second terminal 200 are 16 degrees.

[0070] However, when an obstacle 600 is configured on the main path 500, since there is no avoidance path other than the main path 500 in the beamforming area of ​​the antenna pointing direction 300, a signal quality degrade may occur when a communication failure occurs.

[0071] Figure 5 This is a diagram illustrating the antenna pointing direction setting operation of one embodiment among the plurality of embodiments of the present invention.

[0072] Reference Figure 5 (a) The horizontal rotation direction of the first terminal 100 can be set within the range of -90 degrees to +90 degrees.

[0073] Reference Figure 5 (b) When the position of the first antenna 110 is located at -90 degrees counterclockwise, the first terminal 100 can confirm the effective beam between the first antenna 110 and the second antenna 210 within the beamforming area of ​​the coverage area.

[0074] Reference Figure 5 (c) When the antenna is positioned in the forward direction (0 degrees), the first terminal 100 can confirm the effective beam between the first antenna 110 and the second antenna 210 within the beamforming area of ​​the coverage area.

[0075] Reference Figure 5 (d) When the antenna is located at a counterclockwise +90 degrees, the first terminal 100 can confirm the effective beam between the first antenna 110 and the second antenna 210 within the beamforming area of ​​the coverage area.

[0076] Figure 6 This is a diagram illustrating the communication status of multiple paths in a wireless AV transmission system of one embodiment of the present invention.

[0077] Reference Figure 6 The wireless AV communication system 100 can perform beam scanning between the first antenna 210 of the first terminal 100 and the second antenna 120 of the second terminal 200.

[0078] At this time, the first terminal 100 can calculate the signal quality and beam direction of the plurality of beam pairs generated by beam scanning. To this end, the first terminal 100 can set the position of at least one of the first antennas within the adjustment range of the horizontal rotation and pitch directions of the first antenna, and can perform at least one beam scan based on the set position of the first antenna. Thus, the first terminal 100 can search for valid signals by changing the position of the first antenna 110.

[0079] The first terminal 100 can store beam pairs with signal quality above a reference value from among the calculated plurality of beam pairs as candidate beam paths. To this end, the first terminal 100 can determine whether there is a beam path that meets a preset signal quality among the plurality of beam pairs stored according to the position of the first antenna, and can store the beam path that meets the signal quality.

[0080] For example, the first terminal 100 can search for a valid signal at a -90-degree antenna position and confirm that there is no valid beam that meets the signal quality requirements. The first terminal 100 can search for a valid signal at a 0-degree antenna position and confirm that there is a first valid path 510 at -15 degrees. The first terminal 100 can search for a valid signal at a 90-degree antenna position and confirm that there is a second valid path 520 at -30 degrees.

[0081] The first terminal 100 can set the direction of the first antenna to include a plurality of candidate beam paths within the beamforming region of the first antenna. At this time, the first terminal 100 can confirm whether the directions of the plurality of candidate beam paths are separated by a pre-set value based on a beam table to set effective beam paths. Then, the first terminal 100 can calculate the horizontal rotation direction and pitch direction within the beam control range of the first antenna in the vertical and horizontal directions, considering the number of effective beam paths and signal quality, and can set the direction of the first antenna based on the calculated horizontal rotation direction and pitch direction.

[0082] Therefore, the first terminal 100 can set the optimal antenna direction based on the search results for effective signals. That is, the wireless AV transmission system can set the antenna pointing direction 310 so that the first effective path 510 and the second effective path 520 are located in the beamforming region 410.

[0083] For example, the first terminal 100 can set the antenna direction 300 to a 15-degree clockwise direction from the front.

[0084] For example, the first effective path 510 can be based on the beam table to pair beam 25 of the first terminal 100 and beam 28 of the second terminal 200 and establish communication. At this time, the horizontal rotation and elevation of the antenna pointing direction of the first terminal 100 are 0 degrees, and the horizontal rotation and elevation of the antenna of the second terminal 200 are 16 degrees.

[0085] For example, the second effective path 520 can be based on a beam table to pair beam 25 of the first terminal 100 and beam 28 of the second terminal 200 and establish communication. At this time, the antenna pointing direction of the first terminal 100 has a horizontal rotation value of -45 degrees and an elevation value of 0 degrees, while the antenna of the second terminal 200 has a horizontal rotation value of 33 degrees and an elevation value of 0 degrees.

[0086] Figure 7 This is a diagram illustrating an embodiment of the antenna pointing direction setting guide provided by an embodiment of the present invention.

[0087] Reference Figure 7 The first terminal 100 can display and provide the antenna pointing direction setting guide to the display, corresponding to the set direction of the first antenna.

[0088] The first terminal 100 can provide a horizontal rotation adjustment guide 810 indicating clockwise and counterclockwise directions and the amount of rotation. The first terminal 100 may include a horizontal rotation indicator 820, which indicates whether alignment has occurred as the antenna direction changes, in the event that the first antenna 111 moves according to the calculated horizontal rotation direction.

[0089] The first terminal 100 can provide pitch adjustment guidance 830, which indicates the up and down direction and the amount of rotation of the pitch direction. The first terminal 10 may include a pitch indicator 840, which indicates whether alignment has occurred as the antenna 111 moves according to the calculated pitch direction.

[0090] On the other hand, once the antenna pointing direction is set, the first terminal 100 can change the colors of the horizontal rotation indicator 820 and the pitch indicator 840 and provide a notification to the user.

[0091] In addition, the first terminal 100 can provide guidance on setting the antenna pointing direction via voice.

[0092] For example, the first terminal 100 can output the voice message "For optimal signal quality, rotate the transceiver unit two notches clockwise and adjust it one notch upwards!"

[0093] Figure 8 This is a flowchart illustrating an antenna pointing direction setting method according to an embodiment of the present invention.

[0094] Reference Figure 8 It can measure the link quality of the first terminal 100 and the second terminal 200 and confirm the beam candidate group (S10).

[0095] After step S10, the first terminal 100 can determine whether the beam candidate group at the current position of the first antenna 110 is above the reference value (S20).

[0096] After step S20, the first terminal 100 may store beam candidate group information and signal quality at the current location (S30).

[0097] After step S30, the first terminal 100 can determine whether candidate beam scanning has been completed for all movable positions of the first antenna 110 (S40).

[0098] After step S40, if the candidate beam scanning is not completed, the first terminal 100 can change the antenna direction up, down, left, and right and compare the horizontal and vertical directions of the candidate beam ID, and can provide antenna pointing direction setting guidance (S50).

[0099] After step S50, terminal 100 can perform setup operations according to the instructions (S60).

[0100] After step S40, once the candidate beam scanning is complete, the first terminal 100 can compare the candidate beam direction and signal quality by position and provide antenna direction setting guidance at the optimal position within the beamforming area (S70).

[0101] The first terminal 100 can confirm whether the beam candidate group at the current position is above the reference value (S80). If the beam candidate group at the current position is above the reference value, the antenna pointing direction setting method can be terminated.
