Technical Field

[0001] Embodiments of the present invention relate to, but are not limited to, the field of communication technologies. Specifically, they relate to, but are not limited to, an antenna anti-interference method, a communication device, and a storage medium. Background Art

[0002] How much resources a terminal can obtain and what its maximum download rate is usually depend on the terminal antenna efficiency and communication quality. For example, if there are situations such as poor orthogonality between the terminal antenna and the base station antenna, poor orthogonality among the working antennas of the terminal itself, or antenna interference, it will result in a poor evaluation result of the terminal channel quality by the base station. Consequently, relatively low scheduling resources will be given to this terminal, affecting the throughput of the terminal and limiting the user experience of the terminal. Summary of the Invention

[0003] The antenna anti-interference method, communication device, and storage medium provided by the embodiments of the present invention mainly solve the technical problem that when the terminal antenna efficiency and communication quality are poor, it affects the terminal throughput and reduces the user experience.

[0004] To solve the above technical problem, an antenna anti-interference method provided by an embodiment of the present invention includes:

[0005] Detect the performance parameters of a single antenna and antenna combinations in an antenna sequence group of a communication device. The antenna sequence group is composed of a group of antennas that work simultaneously in different antenna roles, and if any one of the antennas or antenna roles is different, the corresponding antenna sequence group is different;

[0006] Determine the antenna to be adjusted from the antenna sequence group according to the performance parameters;

[0007] Adjust the antenna to be adjusted to reduce the interference received by the antenna sequence group;

[0008] Control the adjusted antenna sequence group to work.

[0009] An embodiment of the present invention also provides a communication device. The communication device includes a processor, a memory, and a communication bus. The communication device also includes multiple antennas;

[0010] The communication bus is used to realize the connection and communication between the processor and the memory;

[0011] The processor is used to execute one or more programs stored in the memory to implement the steps of the above antenna anti-interference method.

[0012] An embodiment of the present invention also provides a computer storage medium. The storage medium stores at least one of the antenna anti-interference programs. The antenna anti-interference program can be executed by one or more processors to implement the steps of the above antenna anti-interference method.

[0013] An embodiment of the present invention further provides a communication device, which includes a plurality of antennas distributed on at least two planes parallel to the display screen of the communication device.

[0014] According to the antenna anti-interference method, communication device and storage medium provided by the embodiments of the present invention, the communication device includes a plurality of antennas, and some or all of these antennas can work with different antenna roles simultaneously, thus forming an antenna sequence group. Changes in the antennas or antenna roles in the antenna sequence group will cause changes in the antenna sequence group. During the operation of the antenna sequence group, the communication device can detect the performance parameters of individual antennas and antenna combinations in the antenna sequence group. Then, according to the performance parameters, the antenna to be adjusted is determined from the antenna sequence group, and the antenna to be adjusted is adjusted. Subsequently, the adjusted antenna sequence group is controlled to work. By detecting the performance parameters of individual antennas and antenna combinations in the antenna sequence group, the communication device can determine the antenna that affects the overall performance of the antenna sequence group, and then adjust this antenna as the antenna to be adjusted, trying to avoid or even completely eliminate the negative impact of the antenna to be adjusted on the overall performance of the antenna sequence group, thereby improving the antenna efficiency and communication quality of the communication device, increasing the throughput of the communication device, and enhancing the user experience.

[0024] In order to make the objectives, technical solutions and advantages of the present invention clearer, the embodiments of the present invention will be further described in detail below through specific implementation manners in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0025] Embodiment 1:

[0026] Generally, the NR (New Radio) part of the current 5G communication device uses 4*4 MIMO (Multiple-in Multiple-out) antennas. If it is NSA (Non-Standalone), 6 antennas may work together; if it is SA (Standalone), 4 antennas may work together. If there is interference or mutual interference between these antennas, the OTA (Over the Air) performance of the communication device will be affected, and the evaluation result of the base station on the channel quality of each antenna channel will be very low. Furthermore, relatively low scheduling resources will be given to this communication device. At the same time, in weak signal conditions, since the received signal strength of the communication device is low, the SNR (Signal Noise Ratio) value is usually also very low. Then, the maximum downlink throughput resources allocated by the base station to the communication device will be very few, resulting in the inability to increase the user's Internet access rate.

[0027] With the development and evolution of communication technologies, there are more and more communication systems and communication frequency bands. For example, communication devices usually need to be compatible with cellular low, medium, and high frequencies, and even UHF (Ultra High Frequency). In addition, there are also WiFi (Wireless Fidelity) communication frequency bands, Bluetooth communication frequency bands, GPS (Global Positioning System) communication frequency bands, etc. In the current 5G communication system, there are also SUB6 GHz (i.e., FR1 frequency band, with a frequency range of 450 MHz - 6 GHz) and MMW (mmWave, millimeter wave, also known as FR2 frequency band, with a frequency range of 24.25 GHz - 52.6 GHz) frequency bands. In terms of communication systems, communication devices need to be compatible with the requirements of 2G, 3G, 4G, and 5G. In terms of frequency bands, they need to cover 600 MHz - 60 GHz. Moreover, in order to pursue higher data transmission rates, communication devices also need to support MIMO multi-antenna and CA (Carrier Aggregation) technologies.

[0028] Currently, since the radio frequency processing units and transceiver links of 4G and 5G are independent of each other, and during the process of signals coming out of the radio frequency transceiver to the antenna front end, the two sets of links need to work simultaneously. That is, when 4G is transmitting, 5G may be receiving; when 5G is transmitting, 4G may be receiving. This situation is particularly obvious in frequency bands with harmonic relationships, such as the coexistence of Sub6 GHz in 4G and 5G, such as the coexistence of Band 3 and Band N78, the coexistence of Band 41 and Band N41. In addition to the coexistence of frequency bands between 4G and 5G, there will also be coexistence interference problems between the cellular communication frequency band of 5G and the WiFi communication frequency band, the Bluetooth communication frequency band and the GPS communication frequency band, such as the coexistence of WiFi 5G and Sub6 N79, and for another example, the coexistence of Sub6 GHz and GNSS (Global Navigation Satellite System), the coexistence of millimeter wave and GPS, the coexistence of millimeter wave and GPS, etc. In the ENDC (EUTRA-NR Dual Connectivity, representing the dual connectivity of other wireless protocols and NR 5G) scenario, due to the very wide frequency band coverage of NR, just the TDD (Time Division Duplexing) NR frequency band includes 3.3 GHz - 40 GHz. If the FDD (Frequency Division Duplexing) NR frequency band of Framing is included, the NR frequency band can cover 650 MHz - 40 GHz, and these frequency bands overlap with the traditional 2G, 3G, 4G, Bluetooth, WiFi, and GPS frequency bands, and most of them need to coexist and work.

[0029] Please refer to Figure 1 the schematic diagram of the antenna distribution of the 5G communication device shown. There are more than 10 antennas in the 5G communication device, and there are more than 30 frequency bands. Each frequency band (such as Band B1) is divided into four channels: main set, diversity, main MIMO, and sub MIMO. Due to different physical devices, each channel will be divided into many branch paths. And due to the increase in radio frequency channels and paths, the routing and layout of each channel need to meet certain compatibility requirements and certain isolation requirements, which has become a very big problem for the PCB (printed circuit board) with limited area. Moreover, in the ENDC dual connection, the harmonic and intermodulation effects between the LTE and NR frequency bands are very large. If the path selection is incorrect, the isolation will be poor, and the sensitivity of LTE and NR will inevitably deteriorate, thereby affecting the communication performance of the communication device and directly affecting the throughput and user experience. Figure 1In it, "ANTn-X" represents the nth antenna in the X frequency band. For example, "ANT1-NR1" represents the 1st antenna in the NR1 frequency band, "ANT2-NR1" represents the 2nd antenna in the NR1 frequency band, "ANT3-NR1" represents the 3rd antenna in the NR1 frequency band, "ANT4-NR1" represents the 4th antenna in the NR1 frequency band; "ANT1-NR2" represents the 1st antenna in the NR2 frequency band, "ANT2-NR2" represents the 2nd antenna in the NR2 frequency band, "ANT3-NR2" represents the 3rd antenna in the NR2 frequency band, "ANT4-NR2" represents the 4th antenna in the NR2 frequency band; "ANT1-4G" represents the 1st antenna in the 4G frequency band; "ANT2-4G" represents the 2nd antenna in the 4G frequency band; "ANT3-4G" represents the 3rd antenna in the 4G frequency band; "ANT4-4G" represents the 4th antenna in the 4G frequency band.

[0030] As the number of antennas in a communication device increases, the efficiency sharing of each antenna becomes lower. For a certain frequency band (such as the N41 frequency band), the layout of 4 MIMO antennas is reasonable, but for another NR frequency band (such as the N78 frequency band), the relative position layout of 4 MIMO antennas is not very reasonable. At the same time, during the use of a communication device (such as a mobile phone), as the position of the communication device changes, the direction of the user using the communication device changes, and the position of the communication device relative to the base station changes, the orthogonality relationship of the communication device antennas changes, and the throughput of the communication device will also be affected accordingly.

[0031] Aiming at the problem that the antenna efficiency and communication quality of a merchant communication device affect the throughput, resulting in a poor communication experience for users, this embodiment provides an antenna anti-interference method. Please refer to Figure 2 the flowchart of the antenna anti-interference method shown in

[0032] S202: The communication device detects the performance parameters of a single antenna and antenna combinations in the antenna sequence group.

[0033] The so-called antenna sequence group is composed of a group of antennas that work with different antenna roles simultaneously in a communication device. Moreover, two antenna sequence groups with different antenna members are different, and two antenna sequence groups with the same antenna members but different antenna roles for each antenna member are also different. For example, in one example, the first antenna sequence group includes four antennas a, b, c, and d, and the second antenna sequence group includes four antennas a, b, c, and e. Since the antenna members of these two antenna sequence groups are different, the first antenna sequence group is different from the second antenna sequence group. Assume that the third antenna sequence group also includes four antennas a, b, c, and d. However, in the third antenna sequence group, antenna a is the main set antenna, antenna b is the diversity antenna, and antennas c and d are MIMO antennas. But in the first antenna sequence group, antenna b is the main set antenna, antenna a is the diversity antenna, and antennas c and d are also MIMO antennas. Therefore, although the antenna members of the first antenna sequence group and the third antenna sequence group are the same, the antenna roles of each antenna are different. Thus, the first antenna sequence group and the third antenna sequence group also belong to different antenna sequence groups.

[0034] When a communication device detects the performance parameters of a single antenna and antenna combinations in an antenna sequence group, it will separately detect the performance parameters of a single antenna in the antenna sequence group and also detect the performance parameters of two or even more antenna combinations in the antenna sequence group. It can be understood that the performance parameter of a single antenna refers to the performance parameter when only a certain antenna is in the working state. And the performance parameter of an antenna combination refers to the overall performance parameter when two or more antennas work together. For example, for an antenna sequence group including four antennas a, b, c, and d, the communication device can separately detect the performance parameters of antennas a, b, c, and d. In addition, the communication device can also detect the performance parameters of the combination of antenna a and antenna b, the combination of antenna a and antenna c, the combination of antenna a and antenna d, etc.

[0035] For example, currently there are four signal paths for the N41 frequency band, namely TRX, DRX, PRX-MIMO, and DRX-MIMO. In other words, for the N41 frequency band, the antenna sequence group of the communication device includes four antenna roles: TRX, DRX, PRX-MIMO, and DRX-MIMO. The communication device can define a total of 15 commands from C1 to C15, and these 15 commands are respectively used to detect the performance parameters of different antennas or different antenna combinations. For example, command C1 is used to control the communication device to enter the DRX-MIMO only (i.e., only the DRX-MIMO antenna works) mode, command C2 is used to control the communication device to enter the PRX-MIMO only (i.e., only the PRX-MIMO antenna works) mode, command C3 is used to control the communication device to enter the PRX-MIMO, DRX-MIMO only (i.e., only the PRX-MIMO antenna and the DRX-MIMO antenna work) mode... Command C8 is used to control the communication device to enter the TRX ONLY (i.e., only the TRX antenna works) mode. Specifically, it can be seen in Table 1. In Table 1, "1" indicates that the antenna works, and "0" indicates that the antenna does not work:

[0036] Table 1

[0038] In this embodiment, when the communication device detects the performance parameters of a single antenna and antenna combinations in the antenna sequence group, it can detect the parameters that can directly reflect the antenna performance. For example, signal strength such as the RSRP (Reference Signal Received Power) value, RSSI (Received Signal Strength Indicator) value, antenna efficiency and gain, directivity, or standing wave ratio, correlation coefficient, or isolation degree, etc. It can also be the parameters that can indirectly reflect the performance, such as SNR value, CQI (Channel Quality Indicator) value, MIMO Rank (rank) signal stream number, MCS (Modulation and Coding Scheme) modulation method and order, etc., or throughput, bit error rate, etc. In some examples of this embodiment, the performance parameters detected by the communication device include, but are not limited to, one or more combinations of the following parameters: RSRP, RSSI, antenna efficiency, antenna gain, antenna direction parameter, antenna standing wave ratio parameter, antenna isolation degree, signal-to-noise ratio SNR, CQI, throughput value, bit error rate, MCS, RANK stream number.

[0039] S204: The communication device determines the antenna to be adjusted from the antenna sequence group according to the performance parameters.

[0040] After detecting the performance parameters corresponding to the antenna sequence group, the communication device can determine the antenna to be adjusted from the antenna sequence group according to the performance parameters. It can be understood that the antenna to be adjusted in the antenna sequence group can be an antenna that is severely interfered, or an antenna that causes severe interference to other antennas; it can be an antenna with poor orthogonality to other antennas, or an antenna with poor orthogonality to the base station antenna.

[0041] In some examples of this embodiment, the communication device can determine the interfered antenna as the antenna to be adjusted according to the detected performance parameters in combination with the coordinate positions of each antenna in the antenna sequence group. In some examples, the communication device can select the most severely interfered antenna as the antenna to be adjusted, or the communication device can select all antennas whose interference degree meets the requirements as the antennas to be adjusted. Optionally, the coordinate positions of each antenna can be pre-stored in the communication device. In this way, when determining the antenna to be adjusted, the communication device can directly determine the antenna with relatively severe interference among each antenna according to the detection result of the performance parameters in combination with the coordinate positions of each antenna pre-stored by itself.

[0042] The coordinate position of the antenna refers to the position of the antenna in the communication device. For example, assuming that the lower left corner of the communication device (it can be understood that the lower left corner is only an example, and it can also be the lower right corner or the center position of the communication device) is used as the coordinate origin to determine the coordinate positions of each antenna. In some examples, the antennas in the communication device are two-dimensionally arranged, that is, all antennas can basically be regarded as being in the same plane. For example, in some mobile phones, each antenna is distributed on the upper and lower clearance areas of the mobile phone back shell and the surrounding frames. When the communication device stores the coordinate positions of each antenna, only the two-dimensional coordinate positions are recorded. In some other examples of this embodiment, the antennas of the communication device can be three-dimensionally arranged. For example, in addition to the antennas arranged in the clearance area and the surrounding frames, there are also some antennas deployed on the main board and sub-boards of the communication device. For example Figure 3 shows the layout of the antennas in a communication device. When the antennas in the communication device are three-dimensionally arranged, the coordinate positions of each antenna pre-recorded and stored in the communication device are also three-dimensional coordinate positions. It should be understood that Figure 3Among them, some antennas are arranged on the main board 31 of the communication device, such as the first NR orthogonal antenna 311, the second NR orthogonal antenna 312, the third NR orthogonal antenna 313, the fourth NR orthogonal antenna 314, the fifth NR orthogonal antenna 315, and the sixth NR orthogonal antenna 316; some antennas are arranged on the daughter board 32 of the communication device, such as the seventh NR orthogonal antenna 321, the eighth NR orthogonal antenna 322, and the ninth NR orthogonal antenna 323. At the same time, some antennas are also arranged on the clearance area of the rear shell and the surrounding frames, such as the NR antenna sequence group A (NR-A1, NR-A2, NR-A3, and NR-A4), the NR antenna sequence group B (NR-B1, NR-B2, NR-B3, and NR-B4), the first LTE antenna 301, the second LTE antenna 302, and the WiFi GPS antenna 303. However, in some other examples of this embodiment, the antennas can be arranged only on the clearance area, the frame, and the main board, or the antennas can be arranged only on the daughter board and the clearance area, or the antennas can be distributed only on the frame and the main board.

[0043] It can be understood that the interference source causing interference to the antennas in the antenna sequence group can be any one of the following several types: other antennas in the antenna sequence group, electronic devices in the communication device, body parts of the communication device user, or other external electronic devices, base stations, etc.

[0044] In some other examples of this embodiment, the communication device can determine the antenna causing interference to other antennas in the antenna sequence group as the antenna to be adjusted according to the detected performance parameters in combination with the coordinate positions of the antennas in the antenna sequence group. For example, the communication device can select the antenna that causes the most serious interference to other antennas in the antenna sequence group as the antenna to be adjusted according to the performance parameters and the coordinate positions, or can select all the antennas that meet the conditions of the interference caused to other antennas as the antennas to be adjusted. In addition, if the antenna layout in the communication device is a two-dimensional layout, the communication device pre-stores the two-dimensional coordinate positions of each antenna. If the layout of each antenna in each communication device is a three-dimensional layout, the communication device will pre-store the three-dimensional coordinate positions of each antenna.

[0045] In some other examples, the communication device can determine the antenna with non-satisfactory orthogonality as the antenna to be adjusted according to the detected performance parameters of the antenna sequence group. It can be understood that the non-satisfactory orthogonality includes at least one of the following two situations:

[0046] First, the orthogonality mismatch between the antennas in the antenna sequence group and the base station antennas;

[0047] Second, the orthogonality mismatch between the antennas in the antenna sequence group and other antennas in the antenna sequence group.

[0048] Optionally, the communication device may determine, based on the performance parameters and in combination with the coordinate positions of the antennas in the antenna sequence group, the antenna that is orthogonally mismatched with other antennas in the antenna sequence group as the antenna to be adjusted. The communication device may also determine, based on the detected performance parameters, the antenna in the antenna sequence group that is orthogonally mismatched with the base station antenna as the antenna to be adjusted.

[0049] It can be understood that, generally, the antennas in the communication device are omnidirectional antennas. In this case, when the communication device determines the antenna that is severely interfered with, severely interferes with other antennas, or whose orthogonality does not meet the requirements as the antenna to be adjusted, it does not need to rely on the radiation directions of the antennas. However, if the antennas in the communication device include directional antennas, then when the communication device determines the antenna to be adjusted, in addition to being able to combine the coordinate positions of the antennas, it can also further combine the radiation directions of the antennas. In these examples, in addition to pre-storing the coordinate positions of the antennas, the communication device can also store the radiation directions of the antennas.

[0050] It should be understood that the communication device does not necessarily have to determine the antenna to be adjusted based on the detected performance parameters and then adjust the antenna to be adjusted in any case. For example, in some examples, if the performance parameters detected by the communication device indicate that the orthogonality of the antennas in the antenna sequence group is good, the isolation degree of each antenna is high, and they are also orthogonal to the base station antenna, and there is basically no interference from the interference source, so the overall performance is excellent, then the communication device does not need to adjust the antenna sequence group, and naturally does not need to select the antenna to be adjusted from the antenna sequence group. Therefore, in some examples, before the communication device determines the antenna to be adjusted from the antenna sequence group based on the detected performance parameters, it will first determine whether the performance parameters corresponding to the antenna sequence group meet the service requirements of the communication device. If the judgment result is yes, the communication device will temporarily not adjust the antenna sequence group. However, if the communication device determines that the detected performance parameters do not meet the service requirements of the communication device, the communication device can determine the antenna to be adjusted from the antenna sequence group with reference to the foregoing examples.

[0051] S206: The communication device adjusts the antenna to be adjusted.

[0052] After the communication device determines the antenna to be adjusted from the antenna sequence group, it can adjust the antenna to be adjusted. By adjusting the antenna to be adjusted, the interference received by the antenna sequence group can be reduced, and the overall performance of the antenna sequence group can be improved. An antenna sequence group may include one antenna to be adjusted, or may include two or even more antennas to be adjusted. In this embodiment, the number of antennas to be adjusted in the antenna sequence group is not limited. For example, in one example, all the antennas in an antenna sequence group can be antennas to be adjusted.

[0053] It can be understood that the adjustment method for the antenna to be adjusted includes any one of the following two methods:

[0054] Method 1: Directly replace the antenna to be adjusted. Please refer to Figure 4 A flowchart showing the adjustment of the antenna to be adjusted:

[0055] S402: Determine a replacement antenna for the antenna to be adjusted.

[0056] In this solution for adjusting the antenna to be adjusted, after the communication device determines the antenna to be adjusted, it is also necessary to determine the replacement antenna for the antenna to be adjusted. It should be understood that if the antenna to be adjusted is an antenna that causes relatively large interference to other antennas in the antenna sequence group, then the replacement antenna corresponding to the antenna to be adjusted should be an antenna that causes basically no interference or relatively small interference to other antennas in the antenna sequence group. In addition, the orthogonality between the antenna to be adjusted and other antennas in the antenna sequence group, as well as the orthogonality with the base station antenna, should also meet the requirements. Otherwise, after replacing the replacement antenna into the antenna sequence group, the replaced antenna will also affect the performance of the antenna sequence group due to orthogonal mismatch; if the antenna to be adjusted is an antenna that is severely affected by the interference source, then its replacement antenna should be basically unaffected by the interference source. At the same time, its replacement antenna should also meet the orthogonality requirements; if the antenna to be adjusted is an antenna that is orthogonally mismatched with other antennas in the antenna sequence group, then its replacement antenna should be an antenna that is basically orthogonal to the antennas in the antenna sequence group. At the same time, the orthogonal situation between the replacement antenna and the base station antenna also meets the requirements, and the replacement antenna is basically not affected by interference and has basically no interference on other antennas.

[0057] Optionally, when the communication device determines a replacement antenna for an antenna to be adjusted, it can be determined according to at least one of the performance parameters and coordinate positions of each antenna on the communication device. It should be understood that in the solution of determining the replacement antenna according to the performance parameters of each antenna, when the communication device detects the performance parameters, it not only requires the detection of the performance parameters of a single antenna and antenna combinations in the antenna sequence group, but also the performance parameters of other antennas outside the antenna sequence group, as well as the performance parameters of the combination of antennas in the antenna sequence group and antennas outside the antenna sequence group. Optionally, in some examples of this embodiment, the communication device can determine the replacement antenna for the antenna to be adjusted only according to the performance parameters of each antenna. In another example of this embodiment, the communication device can determine the replacement antenna according to the coordinate positions of each antenna. In still other examples, the communication device can combine the performance parameters and coordinate positions of each antenna to determine the replacement antenna. In addition, if the antennas in the communication device are directional antennas, the communication device can also determine the replacement antenna according to the radiation directions of each antenna.

[0058] S404: Switch the radio frequency transceiver path originally connected to the antenna to be adjusted to be connected to the replacement antenna.

[0059] After determining the replacement antenna for the antenna to be adjusted, the communication device can disconnect the connection between the antenna to be adjusted and the corresponding radio frequency transceiver path, and connect the radio frequency transceiver path to the replacement antenna, so as to ensure that the radio frequency transceiver path can use the replacement antenna to complete signal transmission and reception in the subsequent process, as Figure 5 shown.

[0060] Method 2: Adjust the radiation angle of the antenna to be adjusted.

[0061] The adjustment scheme of Method 2 is mainly for the non-omnidirectional antenna with adjustable radiation angle in the communication device. For example, if the communication device determines the antenna affected by interference as the antenna to be adjusted according to the performance parameters and the coordinate positions of each antenna in the antenna sequence group, and determines that the interference source is a directional interference source, then during the process of adjusting the antenna to be adjusted, the communication device can first determine the direction of the directional interference source 60 relative to the antenna to be adjusted (NR-1, NR-2, NR-3, NR-4), and then adjust the feed contact of the antenna to be adjusted to the radiation direction of the antenna to be adjusted to avoid the direction where the directional interference source is located. The radiation directions of each antenna after adjustment and the azimuth where the directional interference source 60 is located are as Figure 6 shown.

[0062] S208: The communication device controls the adjusted antenna sequence group to work.

[0063] After the communication device adjusts the antenna to be adjusted in the antenna sequence group, it actually completes the adjustment of the antenna sequence group. In the subsequent process, the communication device can control the adjusted antenna sequence group to perform radio frequency transmission and reception work. It can be understood that only the radiation angles of some antennas in the adjusted antenna sequence group may change compared with the antenna sequence group before adjustment, or some antenna members may change, or all the antenna members of the entire antenna sequence group may change.

[0064] The antenna anti-interference method provided in this embodiment can be executed periodically or aperiodically, so as to ensure that the communication device can adjust the antenna according to the scenario requirements, usage environment conditions, base station antenna direction, etc., improve the orthogonality of the antennas in the antenna sequence group, enhance the anti-interference ability of the antenna, improve the throughput performance of the communication device, and enhance the user experience.

[0065] Embodiment 2:

[0066] Since there is limited space for antenna layout on communication devices, especially mobile terminals and other communication devices, there is a certain degree of interference and mutual coupling between antennas. How to eliminate interference, reduce mutual coupling, how to arrange more antennas in a limited space, and ensure a certain isolation degree between each antenna are the key issues of concern in this field:

[0067] Taking a mobile phone as an example, in the traditional antenna layout scheme, antennas are generally deployed in the clearance areas on the top, bottom, left, and right of the mobile phone. However, as the number of antennas increases, the isolation of some antennas can no longer meet the requirements. The dense deployment of antennas results in insufficient distance between antennas, and the interaction between antennas will generate energy coupling. This strong coupling will reduce the efficiency of the antennas, increase the correlation of each antenna channel of the MIMO antenna, and thus lead to a decrease in the total throughput.

[0068] However, even if the distance between two antennas is very close, if these two antennas are orthogonal to each other, their isolation can be enhanced. In this way, more antennas can be arranged per unit area. Isolation is one of the key parameters of an antenna. The greater the isolation, the smaller the coupling energy between antennas (such as LTE antennas and NR antennas, and each MIMO antenna corresponding to NR), and the better the antenna performance.

[0069] In this embodiment, the antennas on the communication device are three-dimensionally arranged. For example, assuming the communication device is a mobile terminal, the x-axis is parallel to the width direction of the mobile terminal display screen, the y-axis is parallel to the length direction of the mobile terminal display screen, and the z-axis is perpendicular to the mobile terminal display screen. Taking the antenna in the N79 band as an example, there are 4 NR antennas in a traditional 5G mobile terminal, and multiple new miniaturized independent N79 antennas are added here. These newly added N79 antennas are orthogonally distributed with other antennas on the mobile terminal, and these newly added N79 antennas can be located in the gaps around the mobile terminal and on the PCB board, or in the gaps of the middle frame and rear shell structural parts.

[0070] The newly added N79 antennas can be ceramic antennas, microstrip antennas, or other microarray antennas, as long as there are no metal decorative parts or electroplated parts around the antennas and the rear shell. In addition, the newly added N79 antennas can also be PIFA antennas (inverted F antennas), FPC antennas (flexible antennas), or metal antennas. If it is a polarized antenna, such as a microstrip antenna or a dipole antenna, etc., its requirement for physical space isolation is not high. Therefore, more antennas can be arranged per unit area. If it is a microstrip antenna, its requirement for the clearance area is very low, so it is suitable for deployment in the vacant directions of various current full-screen terminals.

[0071] Please refer to Figure 7 , the communication device 70 includes a parameter acquisition module 702, a control module 704, a parameter storage module 706, an orthogonal mismatch adjustment module 708, and an anti-interference adjustment module 710.

[0072] Among them, the parameter acquisition module 702 is used to acquire the performance parameters of each antenna. The acquired performance parameters can be direct parameters, such as the signal strength under each antenna path, such as RSRP value, RSSI value, or can be the efficiency, gain, directivity, or standing wave ratio, correlation coefficient, or isolation degree of each antenna, etc. The performance parameter can also be an indirect parameter, such as SNR value, CQI value, MIMO Rank signal stream number, MCS modulation method and order, throughput, bit error rate, etc. The acquired value of the antenna performance parameter can be collected in real time through the LOG (log) collector built in the communication device 70. The LOG collector captures each reported value and associates each reported value with the antenna or antenna combination in the antenna sequence group.

[0073] The parameter storage module 706 is used to store the coordinate positions of each antenna. For non-omnidirectional antennas, the parameter storage module 706 can also store the radiation angles of each antenna. Assume that each antenna is denoted as A1, A2,... An respectively, and the antennas are arranged orthogonally in 3D three-dimensional. The coordinate positions of these n antennas A1, A2,... An are Y1, Y2,... Yn respectively.

[0074] The control module 704 is used to determine which antenna has problems, which antennas are unbalanced, and which group of antennas has non-orthogonality and produces a deteriorating effect according to the acquired performance parameters combined with the parameter storage module 706. The control module 704 can calculate the antenna directivity and interference angle. During the 5G communication process, usually four NR antennas work before. For example, it can be A1, A2, A3, and A4, or A1, A3, A7, and A8. The radio frequency front-end circuit and each antenna are switched through a switch. At the same time, each antenna combination can also be combined, matched, or reorganized through algorithms or simulation results. For example, if the base station faced by the terminal is in the northeast 45° direction, the best antenna coordinate position combination corresponding to N41 in this direction is Y1, Y3, Y7, Y8. According to the calculation result, the communication device 70 can select the antennas with this coordinate position combination for NR transmission and reception. If the environment changes, the communication device 70 can perform real-time fine-tuning according to the detection results of the performance parameters of each antenna, fine-tune the branch antennas in each antenna combination, or recalculate and select other antenna angle combinations until the best communication state is reached.

[0075] In addition, by adding a carrier or modulation signal with a certain signal strength to the communication device 70, such as the signal strength level RX ref is -60, -70, -80, -90, -100, -110; the parameter acquisition module 702 can acquire the received signal levels RX0, RX1, RX2... RXn returned by each antenna path, and then the control module 704 compares the acquired value with the initial value RX ref and according to their difference RX difDetermine whether there is interference. Since the antennas are arranged according to the coordinate positions of Y1, Y2, …, Yn, the antennas with interference can reflect the interference direction.

[0076] The control module 704 determines the relative position (Bx, By) of the base station with respect to the communication device 70 based on the detection results of the parameter acquisition module 702. At the same time, it detects the relative positions of interference sources such as interfering electronic devices, interfering components, and interfering antennas, such as (Ix, Iy). By detecting the performance parameters of each antenna, the signal strength, and the position direction angle corresponding to the wireless performance parameters, it further determines the orthogonality between the antennas on the communication device 70, between the antennas of the communication device 70 and the base station antennas, determines the influence of each antenna of the communication device 70 by the interference source, and determines the relative azimuth of the interference source, etc.

[0077] The orthogonal mismatch adjustment module 708, connected to the control module 704, is used to adjust the antennas in the antenna sequence group after the control module 704 determines the antenna orthogonal mismatch. The orthogonal mismatch adjustment is mainly achieved by adjusting the antenna array and its combination.

[0078] The signals of the communication device 70 are emitted from each antenna and finally reach the base station after spatial multipath attenuation, refraction, and reflection. If the polarization is strong enough, the signals in different polarization directions will be independent of each other, thereby reducing the bit error rate of uploading and downloading. That is, on the communication device 70, if the polarization modes of one or more groups of antennas are orthogonal to each other, even if the distance between the antennas is very close, the relevant interference and coupling scenarios will be greatly weakened or eliminated. Correspondingly, for the base station transmitting several groups of independent polarization signals, by adjusting and selecting antennas A1, A2, A3, A4 with better orthogonality on the communication device 70 for reception, polarization signals with low interference and uncorrelated attenuation characteristics can be obtained.

[0079] If there are large bit errors in the interaction between the communication device 70 and the base station, and the reason for the high bit error rate is related to the antennas, the control module 704 calculates whether the four antennas currently selected by the communication device 70 are orthogonal, and whether the antennas and the base station antennas are orthogonal. If not, adjustment is started until the ideal orthogonal angle, ideal bit error coefficient, and throughput value are reached. For example, the original antenna sequence group in the N41 frequency band is four antennas A1, A2, A3, A4, but there are large bit errors between this antenna sequence group and the base station, and the reason for the high bit error rate is that antenna A4 is not orthogonal to the base station antenna. Then, the orthogonal mismatch adjustment module 708 can calculate that the four antennas A1, A2, A3, A7 are orthogonal to the base station antenna, and the four antennas A1, A2, A3, A7 also satisfy the orthogonal relationship with each other. Therefore, the orthogonal mismatch adjustment module 708 can perform an antenna selection and switching operation.

[0080] For multiple NR MIMO antennas of the communication device 70 itself, such as A1, A2, A3, and A4, the control module 704 detects through the parameter acquisition module 702 that there is an interaction between them, that is, there is mutual coupling influence or interference, or in the ENDC dual-connection state, the interference influence of the LTE antenna L1 on the antennas A1, A2, A3, and A4. If the control module 704 determines that there is interference influence, the anti-interference adjustment module 710 needs to perform corresponding anti-interference adjustments.

[0081] The anti-interference adjustment module 710 is also connected to the control module 704, and it can be used for antenna anti-interference adjustment. Antenna anti-interference adjustment can be achieved by adjusting the antenna array and its combination, or by adjusting the feeding points of the antennas.

[0082] For example, each polarized antenna is arranged at each free position of the communication device 70, and an adjustment circuit for ground feeding and signal feeding is added to the corresponding position of each antenna, such as a low-voltage or high-voltage tuning switch, a resistor-capacitor-inductor tuning chip, a MEMES tuning chip, etc. It can also be achieved by adding a plurality of single-pole single-throw feeding contact circuits to the antenna, such as adding switches SPST1, SPST2,... SPSTn, and contacts ABCDEF. By changing the feeding point position, the radiation pattern of each antenna will also change. Through array combination control adjustment, the isolation, antenna efficiency, SNR, and ECC (envelope correlation coefficient) of the NR antenna are improved to the threshold value.

[0083] In addition, the anti-interference adjustment module 710 also considers the interference influence of the user's body parts (such as the head and hands) on the antenna performance, the interference influence of different user holding postures on the antenna performance (such as the influence of holding the device horizontally or vertically), the interference influence of the relative position between the base station and the communication device 70 on the antenna performance, and the interference influence of other electronic devices on the antenna performance, etc.

[0084] The antenna control solution provided in this embodiment solves the problem of anti-interference design of MIMO antennas in current 5G communication devices. Aiming at problems such as poor antenna signal, poor directivity, non-orthogonality, poor correlation, and susceptibility to interference in 5G communication device antennas, the antennas are adjusted and controlled according to the scenario requirements and usage environment conditions, improving the anti-interference ability and isolation of each antenna, and enhancing the throughput performance of the communication device.

[0085] Embodiment Three:

[0086] This embodiment provides a communication device, which includes multiple antennas that are three-dimensionally arranged in the communication device. It can be understood that although there are also multiple antennas in current communication devices, these multiple antennas are two-dimensionally arranged and distributed on a plane parallel to the display screen of the communication device. However, in this embodiment, a part of the multiple antennas is arranged on a first plane parallel to the display screen of the communication device, and another part of the antennas is arranged on a second plane parallel to the display screen, and the first plane is different from the second plane.

[0087] In some examples, some of the multiple antennas of the communication device are arranged on at least one of the main board and the daughter board, and another part can be arranged on the rear case of the communication device; or some of the multiple antennas are arranged on at least one of the main board and the daughter board, and the other is arranged on the frame of the communication device. For example, in Figure 3 In the schematic diagram of the antenna layout in the shown communication device, the first NR orthogonal antenna 311, the second NR orthogonal antenna 312, the third NR orthogonal antenna 313, the fourth NR orthogonal antenna 314, the fifth NR orthogonal antenna 315, and the sixth NR orthogonal antenna 316 are arranged on the main board 31 of the communication device; the seventh NR orthogonal antenna 321, the eighth NR orthogonal antenna 322, and the ninth NR orthogonal antenna 323 are arranged on the daughter board 32 of the communication device; at the same time, some antennas are also arranged on the clearance area of the rear case and the surrounding frames, such as the NR antenna sequence group A (NR-A1, NR-A2, NR-A3, and NR-A4), the NR antenna sequence group B (NR-B1, NR-B2, NR-B3, and NR-B4), the first LTE antenna 301, the second LTE antenna 302, and the WiFi GPS antenna 303.

The communication device can determine the position distribution of the antennas on it according to the three-dimensional coordinate positions of the antennas, and can also determine the relative position relationship between the antennas according to the three-dimensional coordinate positions of different antennas. For example, when performing antenna control according to the antenna anti-interference method provided in the foregoing example, the communication device can select antennas with satisfactory orthogonality to replace the antenna to be adjusted in combination with the three-dimensional coordinate positions of each antenna.

[0089] This embodiment also provides a storage medium, which includes a volatile or non-volatile, removable or non-removable medium implemented in any method or technology for storing information such as computer-readable instructions, data structures, computer program modules, or other data. The storage medium includes, but is not limited to, RAM (Random Access Memory), ROM (Read-Only Memory), EEPROM (Electrically Erasable Programmable Read Only Memory), flash memory or other memory technologies, CD-ROM (Compact Disc Read-Only Memory), digital versatile disc (DVD) or other optical disc storage, magnetic cassette, tape, magnetic disk storage or other magnetic storage devices, or any other medium that can be used to store the desired information and can be accessed by a computer.

[0090] One or more computer programs that can be read, compiled, and executed by one or more processors may be stored in the storage medium. In this embodiment, the storage medium may store an antenna anti-interference program, and the antenna anti-interference program can be executed by one or more processors to implement the processes of any of the antenna anti-interference methods described in the foregoing embodiments.

[0091] This embodiment also provides a computer program product, including a computer-readable device, on which the computer program as shown above is stored. In this embodiment, the computer-readable device may include the computer-readable storage medium as shown above. For example, the computer program product includes a communication device, as Figure 8 shown: The communication device 80 includes a processor 81, a memory 82, and a communication bus 83 for connecting the processor 81 and the memory 82. In addition, the communication device 80 also includes a plurality of antennas ( Figure 8 not shown in the figure). Among them, the memory 82 may be the storage medium storing the antenna anti-interference program described above. The processor 81 can read the antenna anti-interference program, compile it, and execute the processes of the antenna anti-interference method described in the foregoing embodiments:

[0092] The processor 81 detects the performance parameters of a single antenna and antenna combinations in the antenna sequence group of the communication device. The antenna sequence group is composed of a group of antennas that work in different antenna roles simultaneously, and if any one of the antennas or antenna roles is different, the corresponding antenna sequence group is different. Subsequently, the processor 81 determines the antenna to be adjusted from the antenna sequence group according to the performance parameters, then adjusts the antenna to be adjusted, and controls the adjusted antenna sequence group to work.

[0093] Optionally, the performance parameters include at least one of RSRP, RSSI, antenna efficiency, antenna gain, antenna direction parameters, antenna standing wave ratio parameters, antenna isolation, signal-to-noise ratio SNR, CQI, throughput value, bit error rate, MCS, and number of RANK streams.

[0094] In some examples of this embodiment, before the processor 81 determines the antenna to be adjusted from the antenna sequence group according to the performance parameters, it first determines that the performance parameters corresponding to the antenna sequence group do not meet the service requirements of the communication device.

[0095] In some examples of this embodiment, when the processor 81 adjusts the antenna to be adjusted, it can determine an alternative antenna for the antenna to be adjusted and switch the radio frequency transceiver path originally connected to the antenna to be adjusted to be connected to the alternative antenna.

[0096] In some other examples of this embodiment, the radiation angle of the antenna to be adjusted is adjusted.

[0097] Optionally, when the processor 81 determines an alternative antenna for the antenna to be adjusted, it can determine an alternative antenna for the antenna to be adjusted based on at least one of the performance parameters and coordinate positions of each antenna on the communication device.

[0098] In some examples of this embodiment, the ways for the processor 81 to determine the antenna to be adjusted from the antenna sequence group according to the performance parameters include at least one of the following:

[0099] Determine the antenna with non-compliant orthogonality in the antenna sequence group as the antenna to be adjusted according to the performance parameters;

[0100] Determine the antenna affected by interference as the antenna to be adjusted according to the performance parameters in combination with the coordinate positions of each antenna in the antenna sequence group;

[0101] Determine the antenna that causes interference to other antennas in the antenna sequence group as the antenna to be adjusted according to the performance parameters in combination with the coordinate positions of each antenna in the antenna sequence group.

[0102] In some examples, when the processor 81 determines the antenna with non-compliant orthogonality in the antenna sequence group as the antenna to be adjusted according to the performance parameters, it can determine the antenna with orthogonal mismatch with other antennas in the antenna sequence group as the antenna to be adjusted according to the performance parameters in combination with the coordinate positions of each antenna in the antenna sequence group; or it can determine the antenna with orthogonal mismatch with the base station antenna in the antenna sequence group as the antenna to be adjusted according to the performance parameters.

[0103] After determining the interfered antenna as the antenna to be adjusted according to the performance parameters and the coordinate positions of the antennas in the antenna sequence group, if the interference source is a directional interference source, when the processor 81 adjusts the antenna to be adjusted, it can first determine the direction of the directional interference source relative to the antenna to be adjusted; then adjust the feed contact of the antenna to be adjusted to the radiation direction of the antenna to be adjusted to avoid the direction where the directional interference source is located.

[0104] In some examples of this embodiment, the communication device 80 can be either a terminal or a CPE (Customer Premise Equipment), where the terminal can be a mobile phone, a tablet computer, a wearable device, a laptop computer, etc.

[0105] In some examples of this embodiment, multiple antennas of the communication device 80 are all located in areas such as the clearance area and the rear case of the communication device. In some examples of this embodiment, some of the multiple antennas of the communication device 80 can be located on at least one of the main board and the daughter board of the communication device 80. In these examples, the antennas can be three-dimensionally arranged, and the three-dimensional coordinate positions of the antennas of the communication device are also stored in the memory 82.

[0106] For the details of the processor 81 executing the antenna anti-interference program to implement the antenna anti-interference method, reference can be made to the introduction in the foregoing embodiments, which will not be elaborated here.

[0107] The communication device provided in this embodiment includes multiple antennas. Some or all of these antennas can work simultaneously in different antenna roles, thus forming an antenna sequence group. Changes in the antennas or antenna roles in the antenna sequence group will cause changes in the antenna sequence group. During the operation of the antenna sequence group of the communication device, it can detect the performance parameters of individual antennas and antenna combinations in the antenna sequence group, and then determine the antenna to be adjusted from the antenna sequence group according to the performance parameters, and adjust the antenna to be adjusted. Subsequently, it controls the operation of the adjusted antenna sequence group. By detecting the performance parameters of individual antennas and antenna combinations in the antenna sequence group, the communication device can determine the antennas in the antenna sequence group that affect the overall performance of the antenna sequence group, and then adjust this antenna as the antenna to be adjusted, trying to avoid or even completely eliminate the negative impact of the antenna to be adjusted on the overall performance of the antenna sequence group, thereby improving the antenna efficiency and communication quality of the communication device, increasing the throughput of the communication device, and enhancing the user experience.
