It is understood explicitly and implicitly by those skilled in the art that the embodiments described herein can be combined with other embodiments.

The executor of the antenna coexistence and mutual interference processing method provided in the embodiment of the present application may be the antenna coexistence and mutual interference processing device provided in the embodiment of the present application, or an electronic device integrated with the antenna coexistence and mutual interference processing device ( For example, a handheld computer, a tablet computer, a smart phone, etc.), the antenna coexistence and mutual interference processing device may be implemented in a hardware or software manner.

In the same electronic device, multiple wireless access technologies usually coexist at the same time, for example, a long term evolution (LongTerm Evolution, LTE) network and a wireless local area network (Wireless Local Area Networks, WLAN) coexist. When multiple wireless networks are used at the same time, coexistence and mutual interference are prone to occur. For example, according to the current spectrum division and use of wireless communication networks, part of the spectrum of LTE exists in the 2.4GHz frequency band (2400-2483.5MHz) very close to WLAN, especially B40, B41, B7, etc., where B40 (2300-2400MHz) is located below the WLAN frequency band, B41 (2496-2690MHz) and B7 (uplink UL: 2500-2570MHz, downlink DL: 2620-2690MHz) are located above the WLAN frequency band, When the LTE working frequency band is adjacent to the WLAN working frequency band, since the coexistence filter of the current technological level cannot absolutely reduce the interference of the adjacent frequency band to a state of no influence, it is easy to cause coexistence and mutual interaction between the two when they work at the same time. disturb.

To solve the coexistence and mutual interference between LTE and WLAN, we can start from the following aspects:

(1) Time domain, LTE and WLAN adopt time division working mechanism;

(2) Airspace, increasing the antenna isolation between LTE and WLAN;

(3) Frequency domain, increasing the interval between LTE and WLAN operating frequency bands, essentially increasing board-level isolation;

(4) In the code domain, the working rate of different modulation methods is selected to reduce the effective bandwidth, thereby increasing the working frequency interval;

(5) Others, reduce the transmit power of LTE or WLAN.

The embodiment of the present application can be considered from the perspective of the airspace. When the LTE and WLAN adjacent frequency operations generate mutual interference, the isolation between the LTE antenna and the WLAN antenna is improved by selecting LTE antennas and WLAN antennas with different polarization directions, thereby reducing the LTE antenna. Mutual interference with WLAN.

There are various polarization directions of the antenna. For example, the polarization directions of the antenna include horizontal polarization, vertical polarization, circular polarization, and elliptical polarization. Among them, horizontal polarization and vertical polarization belong to the category of linear polarization, and circular polarization and elliptical polarization belong to the category of circular polarization. Taking smartphones as an example, mobile phone antennas are usually linearly polarized. Linear polarization and circular polarization are usually related to the form and structure of the antenna, and horizontal polarization and vertical polarization are related to the installation direction of the antenna. Theoretically, the isolation between antennas whose polarization directions are perpendicular to each other is infinite.

For example, the electronic device provided in this embodiment of the present application may include multiple LTE antennas and multiple WLAN antennas. For example, multiple linearly polarized antennas are respectively designed for the LTE antenna and the WLAN antenna, and the multiple LTE antennas may include LTE antenna 1, LTE antenna 2, . . . LTE antenna N. The multiple WLAN antennas may include WLAN antenna 1, WLAN antenna 2, ... WLAN antenna N. For example, the polarization directions of the LTE antenna 1 and the WLAN antenna 1 are perpendicular to each other, the polarization directions of the LTE antenna 2 and the WLAN antenna 2 are perpendicular to each other, and so on. Among them, the purpose of designing multiple antennas for LTE and WLAN is that when the LTE antenna and the WLAN antenna work separately, the antenna with the smallest polarization loss between the wireless network access point AP or the base station can be selected as the corresponding working antenna to ensure that LTE and WLAN Maximization of WLAN respective performance. The purpose of vertically arranging the polarization directions of the LTE antenna and the WLAN antenna in turn is to improve the isolation between the LTE antenna and the WLAN antenna through the different antenna polarization directions when the LTE antenna and the WLAN antenna work in adjacent frequency bands, thereby maximizing Minimize the coexistence impact of WLAN and LTE.

Please refer to FIG. 1 . FIG. 1 is a schematic flowchart of a method for processing antenna coexistence and mutual interference provided in an embodiment of the present application. The method is applied in an electronic device, and the method includes:

Step 101 , judging whether there is coexistence and mutual interference between an LTE antenna and a working antenna of a WLAN antenna, wherein the LTE antenna is used to transmit LTE signals, and the WLAN antenna is used to transmit WLAN signals. If yes, execute step 102; if not, execute step 104.

Wherein, the working antenna of the LTE antenna and the working antenna of the WLAN antenna in the current working state may be antennas whose polarization directions are not perpendicular to each other.

Wherein, in a default working state, the LTE antenna and the WLAN antenna respectively select the antenna with the best signal quality from multiple LTE antennas and multiple WLAN antennas as their respective working antennas for communication. For example, the LTE antenna 1 with the best signal quality is selected from multiple LTE antennas as the working antenna of the LTE antenna for communication, and the WLAN antenna 3 with the best signal quality is selected from the multiple WLAN antennas as the working antenna of the WLAN antenna for communication. However, when two antennas work at the same time, mutual interference may occur.

In some embodiments, the electronic device may periodically detect whether there is coexistence and mutual interference between the working antennas of the LTE antenna and the WLAN antenna within a preset time period.

In some embodiments, the electronic device may also detect whether there is coexistence and mutual interference between the LTE antenna and the working antenna of the WLAN antenna when it is determined that the LTE antenna and the working antenna of the WLAN antenna are in the working state at the same time.

Wherein, the working antenna of the LTE antenna and the WLAN antenna are in the working state at the same time, which may include the following two states, specifically:

(1) The LTE mobile data network uses data traffic, and the WLAN data network is not connected to the wireless network access point AP but is performing active scanning;

(2) The LTE mobile data network is in a call scene, and the WLAN data network is connected to the wireless network access point AP to access the Internet or perform active scanning.

In some embodiments, as shown in FIG. 2, step 101 may be implemented through steps 1011 to 1013, specifically:

Step 1011, determine whether the LTE signal transmitted by the working antenna of the LTE antenna and the WLAN signal transmitted by the working antenna of the WLAN antenna are signals of adjacent frequency bands.

Wherein, when the LTE antenna and the WLAN antenna are in the working state at the same time, the working frequency bands of the LTE signal transmitted by the working antenna of the LTE antenna and the WLAN signal transmitted by the working antenna of the WLAN antenna are acquired respectively. For example, if the working frequency band of the LTE signal is 2300-2400MHz, that is, the corresponding working channel is B40, and the working frequency band of the WLAN signal is 2400-2483.5MHz, then determine the LTE signal transmitted by the working antenna of the LTE antenna and the WLAN antenna The WLAN signal transmitted by the working antenna is a signal of an adjacent frequency band, and there may be coexistence and mutual interference. For example, if the working frequency band of the LTE signal is uplink UL: 880-915MHz, downlink DL: 925-960MHz, that is, the corresponding working channel is B8, and the working frequency band of the WLAN signal is 2400-2483.5MHz, then determine the LTE antenna The LTE signal transmitted by the working antenna of the WLAN antenna and the WLAN signal transmitted by the working antenna of the WLAN antenna are signals in non-adjacent frequency bands, and coexistence and mutual interference are not likely to exist.

Step 1012, if the LTE signal transmitted by the working antenna of the LTE antenna and the WLAN signal transmitted by the working antenna of the WLAN antenna are signals in adjacent frequency bands, then determine the adjacent channel leakage between the LTE signal and the WLAN signal Whether the ratio is less than the first threshold.

Wherein, the adjacent channel leakage ratio (Adjacent Channel Leakage Ratio, ACLR) refers to the ratio of the transmit power of the main channel to the measured carrier power of adjacent or alternate radio frequency channels. Coexistence interference between antenna systems operating in adjacent frequency bands is caused by imperfections in the transmitter and receiver. The transmitter will generate out-of-band radiation when it transmits useful signals, and the out-of-band radiation includes adjacent frequency radiation and out-of-band spurious radiation caused by modulation. Adjacent channel leakage ratio ACLR is usually used to measure the ability of the adjacent channel transmitted signal to fall into the passband of the receiver, that is, the ratio of the transmitted power to the measured power on the adjacent channel, where the measured power on the adjacent channel The power is equivalent to the sum of the normal received power and the power generated by the interference signal. While the receiver is receiving the useful signal, the interference signal falling into the channel may cause the loss of receiver sensitivity and cause coexistence interference. Among them, if the transmit power is a fixed value, the greater the measured power on the adjacent channel, the more interference signals fall into the adjacent channel, which means the smaller the adjacent channel leakage ratio, the receiver The poorer the received signal quality, the greater the interference. If the transmit power is a fixed value, the smaller the measured power on the adjacent channel is, the smaller the interference signal falling into the adjacent channel is, and the larger the adjacent channel leakage ratio is, the greater the receiver’s received signal is. The better the signal quality, the less interference there is.

Step 1013, if the adjacent channel leakage ratio is smaller than the first threshold, determine that there is coexistence and mutual interference between the working antennas of the LTE antenna and the WLAN antenna.

Wherein, only by ensuring that the adjacent channel leakage is maintained above the first threshold, can the antenna receive complete signals, and if the adjacent channel leakage ratio is smaller than the first threshold, it means that the antenna cannot receive complete signals, It is determined that there is coexistence and mutual interference between the LTE antenna and the working antenna of the WLAN antenna.

Step 102 , detecting whether one of the working antennas of the LTE antenna and the WLAN antenna is transmitting a signal and the other is receiving a signal within the same period of time. If yes, execute step 103; if not, execute step 104.

Wherein, the working antennas of the LTE antenna and the WLAN antenna may have a situation that one transmits a signal and the other receives a signal in the same period of time, and there may also be a situation that a signal is transmitted or received at the same time. Wherein, if there is coexistence and mutual interference between the working antenna of the LTE antenna and the WLAN antenna, if there is a situation where one of the LTE antenna and the working antenna of the WLAN antenna transmits a signal and the other receives a signal during the same period, such as the LTE antenna The working antenna (such as LTE antenna 1) is in the state of transmitting signals, and the working antenna of the WLAN antenna (such as WLAN antenna 3) is in the state of receiving signals, then the WLAN signal received by the working antenna of the WLAN antenna will be received by the working antenna of the LTE antenna. If the LTE signal in the adjacent frequency band is not affected, then step 103 is performed.

If the working antennas of the LTE antenna and the WLAN antenna simultaneously transmit signals or receive signals within the same time period, and the two antennas do not interfere with each other in the working sequence, step 104 may be performed.

Step 103, adjusting the working antennas of the LTE antenna and the WLAN antenna to the first LTE antenna and the first WLAN antenna whose polarization directions are perpendicular to each other, respectively.

For example, according to the current working strategies of the WLAN data network and the LTE mobile data network, the scenarios where WLAN and LTE interfere with each other include: (1) The LTE mobile data network uses data traffic, and the WLAN data network is not connected to the wireless network access point AP but in Execute active scanning; (2) The LTE mobile data network is in a call scene, and the WLAN data network is connected to a wireless network access point to surf the Internet or perform active scanning.

Based on the above scenarios, the priority of the LTE mobile data network is generally higher than that of the WLAN. In the embodiment of this application, when the working antennas of the WLAN antenna and the LTE antenna work in adjacent frequency bands at the same time, the LTE performance priority is also higher. . That is, when the WLAN antenna and the working antenna of the LTE antenna coexist and interfere with each other, the LTE antenna is controlled to preferentially select the LTE antenna with the best communication quality as the LTE working antenna from the multiple LTE antennas existing in the electronic device, for example, the best communication quality is selected. The LTE antenna 1 is the LTE working antenna, and then the WLAN selects the WLAN antenna perpendicular to the planned direction of the LTE antenna with the best communication quality from the multiple WLAN antennas existing in the electronic device as the WLAN working antenna. The WLAN antennas 1 whose polarization directions are perpendicular to each other are WLAN working antennas.

For example, in the current working state, the LTE antenna 1 with the best signal quality is selected from multiple LTE antennas as the working antenna of the LTE antenna for communication, and the WLAN antenna 3 with the best signal quality is selected from the multiple WLAN antennas as the WLAN antenna. Working antenna for communication. When it is detected that there is coexistence and mutual interference between the LTE antenna 1 and the WLAN antenna 3, and the LTE antenna 1 and the WLAN antenna 3 have a situation where one transmits a signal and the other receives a signal within the same period of time, the LTE antenna and the WLAN antenna The working antennas are respectively adjusted to the first LTE antenna and the first WLAN antenna whose polarization directions are perpendicular to each other. For example, the first LTE antenna and the first WLAN antenna whose polarization directions are perpendicular to each other are respectively LTE antenna 1 and WLAN antenna 1, or LTE Antenna 2 and WLAN Antenna 2. For example, keep the working antenna of the LTE antenna at LTE antenna 1, and adjust the working antenna of the WLAN antenna from WLAN antenna 3 to WLAN antenna 1. For example, the working antenna of the LTE antenna is adjusted from LTE antenna 1 to LTE antenna 2, and the working antenna of the WLAN antenna is adjusted from WLAN antenna 3 to WLAN antenna 2.

Step 104, keep the working antennas of the LTE antenna and the WLAN antenna unchanged.

In some embodiments, if there is no co-existence and mutual interference between the working antennas of the LTE antenna and the WLAN antenna, the original strategy is implemented to keep the working antennas of the LTE antenna and the WLAN antenna unchanged. Wherein, in a default state, the working antennas of the LTE antenna and the WLAN antenna are respectively selected as the corresponding antennas with the best signal quality for communication. When there is no coexistence and mutual interference, the working antennas of each antenna are still working in the default state. For example, the working antenna of the LTE antenna maintains the LTE antenna 1 with the best signal quality for communication, and the working antenna of the WLAN antenna maintains the signal quality. Best quality WLAN antenna 3 for communication.

In some embodiments, if one of the working antennas of the LTE antenna and the WLAN antenna does not transmit a signal and the other receives a signal during the same period of time, the original strategy is implemented, and the LTE antenna and the WLAN antenna are connected to each other. The working antenna remains unchanged. Wherein, in a default state, the working antennas of the LTE antenna and the WLAN antenna are respectively selected as the corresponding antennas with the best signal quality for communication. When the working antennas of the LTE antenna and the WLAN antenna transmit signals or receive signals at the same time, the working antennas of each antenna are still working in the default state. For example, the working antenna of the LTE antenna is maintained at the best signal quality. The LTE antenna 1 performs communication, and the working antenna of the WLAN antenna maintains the WLAN antenna 3 with the best signal quality for communication.

In some embodiments, before adjusting the signal modulation mode of the WLAN antenna from the first modulation mode to the second modulation mode, the method further includes:

Judging whether the frequency band interval between the working frequency band of the LTE signal and the working frequency band of the WLAN signal is less than a preset interval;

If the frequency band interval between the working frequency band of the LTE signal and the working frequency band of the WLAN signal is less than the preset interval, the working antennas of the LTE antenna and the WLAN antenna are respectively adjusted to the first LTE antenna whose polarization directions are perpendicular to each other. antenna and the first WLAN antenna.

In some embodiments, after detecting whether there is a situation that one of the working antennas of the LTE antenna and the WLAN antenna is transmitting a signal and the other is receiving a signal within the same period of time, it further includes:

If there is no situation that one of the working antennas of the LTE antenna and the WLAN antenna transmits signals and the other receives signals during the same period of time, the working antennas of the LTE antenna and the WLAN antenna remain unchanged.

In some embodiments, after adjusting the working antennas of the LTE antenna and the WLAN antenna respectively to the first LTE antenna and the first WLAN antenna whose polarization directions are perpendicular to each other, further comprising:

acquiring the signal quality of the WLAN signal transmitted by the first WLAN antenna;

If the signal quality of the WLAN signal is lower than the second threshold, adjusting the working channel of the WLAN signal to a channel far away from the working frequency band of the LTE signal transmitted by the first LTE antenna.

All the above optional technical solutions can be combined in any way to form an optional embodiment of the present invention, which will not be repeated here.

Please refer to FIG. 3 . FIG. 3 is another schematic flowchart of a method for processing antenna coexistence and mutual interference provided in an embodiment of the present application. The methods include:

Step 201, judging whether there is coexistence and mutual interference between the LTE antenna and the working antenna of the WLAN antenna, where the LTE antenna and the WLAN antenna are located adjacent to each other. If yes, go to step 202; if not, go to step 207.

Wherein, step 201 may refer to step 101, which will not be repeated here.

Step 202 , detecting whether one of the working antennas of the LTE antenna and the WLAN antenna is transmitting a signal and the other is receiving a signal during the same period of time. If yes, go to step 203; if not, go to step 207.

Wherein, the working antennas of the LTE antenna and the WLAN antenna may have a situation that one transmits a signal and the other receives a signal in the same period of time, and there may also be a situation that a signal is transmitted or received at the same time. Wherein, if there is coexistence and mutual interference between the working antenna of the LTE antenna and the WLAN antenna, if there is a situation where one of the LTE antenna and the working antenna of the WLAN antenna transmits a signal and the other receives a signal during the same period, such as the LTE antenna The working antenna (such as LTE antenna 1) is in the state of transmitting signals, and the working antenna of the WLAN antenna (such as WLAN antenna 3) is in the state of receiving signals, then the WLAN signal received by the working antenna of the WLAN antenna will be received by the working antenna of the LTE antenna. If the influence of the LTE signal of the adjacent frequency band is affected, then step 203 is performed.

If the working antennas of the LTE antenna and the WLAN antenna simultaneously transmit signals or receive signals within the same time period, and the two antennas do not interfere with each other in the working sequence, step 207 may be performed.

Step 203, judging whether the frequency band interval between the working frequency band of the LTE signal and the working frequency band of the WLAN signal is smaller than a preset interval. If yes, go to step 204; if not, go to step 207.

Wherein, if the working antenna of the LTE antenna and the WLAN antenna has a situation where one transmits a signal and the other receives a signal during the same period of time, for example, the LTE antenna is in the state of transmitting signals, and the WLAN antenna is in the state of receiving signals, then when the two signals appear In the case of coexistence and mutual interference, the size of the frequency band interval of the working frequency band between the two signals is inversely proportional to the size of the spurious signal falling on the adjacent frequency band. The bigger the signal. When mutual interference occurs between the WLAN antenna and the LTE antenna, the critical point of the working frequency band interval where the mutual interference occurs between the WLAN antenna and the LTE antenna can be measured by the development engineer of the electronic device before leaving the factory. Find the working frequency interval between each two antennas at the critical point between mutual interference and non-interference, so as to obtain the maximum frequency interval when mutual interference occurs between the WLAN antenna and the LTE antenna, and take the maximum frequency interval as the final output value and written into the program, the maximum frequency interval can be set as the preset interval. When the electronic device is working, if it is detected that the frequency band interval between the working frequency bands of the WLAN antenna and the LTE antenna is smaller than the preset interval, it means that the spurious signals falling on the adjacent frequency bands are relatively large and the interference is strong, and step 204 needs to be executed. If it is detected that the frequency band interval between the working frequency bands of the WLAN antenna and the LTE antenna is greater than the preset interval, it means that the spurious signals falling on adjacent frequency bands are small and the interference is small, and step 207 may be executed.

In step 204, the working antennas of the LTE antenna and the WLAN antenna are respectively adjusted to a first LTE antenna and a first WLAN antenna whose polarization directions are perpendicular to each other.

For example, in the current working state, the LTE antenna 1 with the best signal quality is selected from multiple LTE antennas as the working antenna of the LTE antenna for communication, and the WLAN antenna 3 with the best signal quality is selected from the multiple WLAN antennas as the WLAN antenna. Working antenna for communication. When it is detected that there is coexistence and mutual interference between the LTE antenna 1 and the WLAN antenna 3, and the LTE antenna 1 and the WLAN antenna 3 have a situation where one transmits a signal and the other receives a signal within the same period of time, the LTE antenna and the WLAN antenna The working antennas are respectively adjusted to the first LTE antenna and the first WLAN antenna whose polarization directions are perpendicular to each other. For example, the first LTE antenna and the first WLAN antenna whose polarization directions are perpendicular to each other are respectively LTE antenna 1 and WLAN antenna 1, or LTE Antenna 2 and WLAN Antenna 2. For example, keep the working antenna of the LTE antenna at LTE antenna 1, and adjust the working antenna of the WLAN antenna from WLAN antenna 3 to WLAN antenna 1. For example, the working antenna of the LTE antenna is adjusted from LTE antenna 1 to LTE antenna 2, and the working antenna of the WLAN antenna is adjusted from WLAN antenna 3 to WLAN antenna 2.

Step 205, acquire the signal quality of the WLAN signal transmitted by the WLAN antenna.

Wherein, after adjusting the working antennas of the LTE antenna and the WLAN antenna to the first LTE antenna and the first WLAN antenna whose polarization directions are perpendicular to each other, although the isolation between the LTE antenna and the WLAN antenna is increased to a certain extent , thereby reducing the mutual interference effect between LTE and WLAN, but the working frequency band between the WLAN antenna and the LTE antenna is still an adjacent frequency band, and the WLAN antenna may have low transmission performance, so it is necessary to further obtain the WLAN antenna The signal quality of the transmitted WLAN signal is used to determine the quality of the transmission performance of the WLAN antenna. For example, detect WLAN antenna signal to interference plus noise ratio SINR (Signal to Interference plus Noise Ratio), reference signal received power RSRP (Reference Signal Receiving Power), received signal strength indication RSSI (Received Signal Strength Indication) and other parameters to determine the acquisition of WLAN antenna signal quality.

Step 206: If the signal quality of the WLAN signal is lower than a second threshold, adjust the working channel of the WLAN signal to a channel far away from the working frequency band of the LTE signal transmitted by the first LTE antenna.

Wherein, for example, the signal quality of the WLAN signal is represented by a received signal strength indicator RSSI, for example, the second threshold is set to -95dBm, and if the RSSI of the WLAN signal is -102dBm, it indicates that the signal quality of the WLAN signal is Below the second threshold, the current working channel of the WLAN antenna cannot maintain normal signal transmission, and the working channel of the WLAN signal is adjusted to a channel far away from the working frequency band of the LTE signal transmitted by the first LTE antenna. For example, the current working channel of the WLAN antenna is channel 1 (the center frequency is 2412 MHz), and the working channel of the LTE signal transmitted by the first LTE antenna is B40 (the working frequency band is 2300-2400 MHz), if the signal quality of the WLAN signal is low At the second threshold, the working channel of the WLAN signal is adjusted from channel 1 to channel 11 (center frequency is 2462MHz) away from the working frequency band of the LTE signal transmitted by the first LTE antenna, so that the working frequency band of the WLAN signal is as far as possible Keep away from the working frequency band of the LTE signal, so as to further increase the isolation between antennas.

Step 207, keep the working antennas of the LTE antenna and the WLAN antenna unchanged.

In some embodiments, if there is no co-existence and mutual interference between the working antennas of the LTE antenna and the WLAN antenna, the original strategy is implemented to keep the working antennas of the LTE antenna and the WLAN antenna unchanged. Wherein, in a default state, the working antennas of the LTE antenna and the WLAN antenna are respectively selected as the corresponding antennas with the best signal quality for communication. When there is no coexistence and mutual interference, the working antennas of each antenna are still working in the default state. For example, the working antenna of the LTE antenna maintains the LTE antenna 1 with the best signal quality for communication, and the working antenna of the WLAN antenna maintains the signal quality. Best quality WLAN antenna 3 for communication.

In some embodiments, if one of the working antennas of the LTE antenna and the WLAN antenna does not transmit a signal and the other receives a signal during the same period of time, the original strategy is implemented, and the LTE antenna and the WLAN antenna are connected to each other.
