Description

[Technical Field]

[0001] This application claims priority from Chinese Patent Application No. 202211723338.0 filed on December 30, 2022, the entire contents of which are incorporated by reference.

[0002] The present disclosure relates to the field of communications technology, and in particular to a method for adjusting a terminal network to prevent mutual interference, a terminal, and a computer-readable storage medium. [Background technology]

[0003] With the development of 5G terminals, WiFi has evolved from WiFi 5 to WiFi 6 and WiFi 7, and the WiFi band has increased from the conventional 2.4G to 5G and 6G, reaching a maximum of 7.2G. In addition, with the development of 5G NR (New Radio) technology, the downlink and uplink NR have evolved from a single NR band to 2CA and 3CA, and may evolve to 5CA and 6CA in the future, where CA stands for Carrier Aggregation.

[0004] As users demand higher speeds, multi-network fusion technology has emerged, i.e., a single WiFi band and a single NR band can transmit and receive simultaneously in parallel, rather than operating independently, and the multiple-input multiple-output (MIMO) between them can also transmit and receive simultaneously in parallel, and the system throughput rate is the joint throughput rate of these.

[0005] Regarding the convergence between WiFi 2.4G, WiFi 5G, WiFi 6G and NR, the convergence between WiFi 2.4G, WiFi 5G and NR is called three-network convergence, the convergence between WiFi 2.4G, WiFi 5G, WiFi 6G and NR is called four-network convergence, and the convergence between WiFi 2.4G, WiFi 5G, WiFi 6G, N78 and N79 is called five-network convergence.

[0006] Currently, WiFi-enabled electronic devices such as 5G terminals and 5G customer premises equipment (CPE) face the problem of mutual interference between WiFi and NR. WiFi 7 will eventually introduce the WiFi 6G band, which will bring the WiFi frequency closer to NR, but the mutual interference problem between WiFi and NR will become even more severe. Therefore, achieving simultaneous WiFi and NR transmission under multi-network convergence is a major challenge. Summary of the Invention

[0011] In order to enable those skilled in the art to better understand the technical solutions of the present disclosure, the terminal network anti-interference coordination method, terminal, and computer-readable medium provided by the present disclosure are described in detail below in combination with the drawings.

[0012] Although exemplary embodiments will be described in detail below with reference to the drawings, the exemplary embodiments may be embodied in different forms and should not be construed as being limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the present disclosure to those skilled in the art.

[0013] The respective embodiments and the respective features in the embodiments of the present disclosure can be combined with each other unless they are inconsistent.

[0014] As used in this disclosure, the term "and / or" includes any and all combinations of one or more of the associated listed items.

[0015] The terms used in this disclosure are for the purpose of describing particular embodiments only and are not intended to limit the disclosure. As used in this disclosure, the singular forms "a," "an," and "the" are intended to include the plural forms unless the context clearly dictates otherwise. It will be further understood that the use of the terms "comprising," "consisting of," and "including" herein specifies the presence of said features, wholes, steps, operations, elements, and / or components, but does not exclude the presence or addition of one or more other features, wholes, steps, operations, elements, components, and / or groups thereof.

[0016] With the introduction of MIMO technology in WiFi and NR, the number of WiFi and NR antennas in devices is increasing. WiFi antennas have evolved from the traditional one or two to four or eight, with each high-frequency NR band having at least four antennas and the two NR bands having at least eight. Due to limited layout space in devices, WiFi and NR antennas are interleaved and have significant mutual coupling. Isolation is an important indicator of antenna mutual coupling; the greater the mutual coupling between antennas, the worse the isolation. Given the limited layout space within devices, it is difficult to meet the isolation requirements for WiFi and NR antennas. The operation of one antenna affects the normal operation of other antennas, reducing antenna efficiency and affecting the antenna's over-the-air (OTA) performance.

[0017] Factors that cause mutual interference include the following (1) to (3): (1) The operating bands or frequency points of the signals are the same or similar, such as WiFi and Bluetooth®, or WiFi and B41 or N41. (2) Harmonic or intermodulation interference: For example, the second or third harmonic operating in one mode is in another band, affecting the reception of the other band signal. (3) Spurious interference: For example, when operating in one band, the resulting spurious signal is in the bandwidth range of the other band, causing mutual interference.

[0018] Mutual interference affects terminal data services. Under weak WiFi or NR signals, the WiFi and NR Total Isotropic Sensitivity (TIS) performance is affected by mutual interference. This results in an increased WiFi or NR block error rate and reduced throughput performance. This results in lower total throughput performance under multi-network convergence, resulting in the lack of comprehensive throughput benefits. This limits the user's uplink service capacity and rate, preventing data service applications that rely on WiFi or NR from functioning properly. Mutual interference also affects voice services. Under weak WiFi or NR signals, WiFi interference with NR reduces the NR network signal quality, resulting in poor reception of 5G text messages and VoNR phone calls. The impact of mutual interference on both data and voice services degrades the user experience.

[0019] Factors that affect WiFi and NR interference include the distance and location between the WiFi antenna and the NR antenna, the maximum power and sensitivity limit for current WiFi and NR operation, the operating frequency and channel of WiFi and NR, the antenna gain of WiFi and NR, the radiation directivity of WiFi and NR, the conduction and antenna isolation between WiFi and NR, and the relative polarization angle between the WiFi and NR antenna.

[0020] To solve the problem of WiFi and NR mutual interference, several related technologies have adopted the following solutions: (1) Separating the physical layout between the WiFi antenna and the NR antenna to reduce their coupling. However, due to the limited space on the terminal's printed circuit board (PCB), it is often impossible to completely separate the physical locations of the WiFi antenna and the NR antenna. (2) Adding a filter between WiFi and NR to filter out the frequency ranges that mutually affect each other. However, while the filter can filter out the effects at the circuit board level, it cannot completely resolve the effects of spatial coupling. (3) Adding an enable control line between WiFi and NR to prevent both from operating simultaneously. (4) Backing off the WiFi or NR power and reducing the maximum transmit power to reduce mutual interference. However, reducing the WiFi or NR power sacrifices the performance of WiFi and NR under weak signal conditions. (5) Restricting the frequency point allows WiFi and NR to operate at different frequency points. However, WiFi operating channels, frequency points, and bands are often relatively fixed and cannot be dynamically switched and adjusted.

[0021] In a first aspect, referring to FIG. 1, an embodiment of the present disclosure provides a method for coordinating mutual interference prevention in a terminal network, including the following steps S1 to S3.

[0022] In step S1, it is determined whether the mobile network and the WiFi network of the terminal interfere with each other.

[0023] In step S2, in response to the mobile network and the WiFi network interfering with each other, a mutual interference path along which the mobile network and the WiFi network interfere with each other is determined.

[0024] In step S3, the mutual interference prevention is adjusted based on the mutual interference path.

[0025] In the presently disclosed embodiment, the mobile network is not particularly limited. For example, the mobile network may be a 5G network, and the 5G network may be represented by NR.

[0026] In the disclosed embodiments, the mutual interference path includes at least one of an antenna path and a conduction path. In some embodiments, a mobile network supports multiple antenna paths and multiple conduction paths, and a WiFi network also supports multiple antenna paths and multiple conduction paths. When mutual interference occurs, not all antenna paths and conduction paths usually interfere with each other, but rather one or more antenna paths or conduction paths of the mobile network interfere with one or more antenna paths or conduction paths of the WiFi network, or one or more antenna paths or conduction paths of the WiFi network interfere with one or more antenna paths or conduction paths of the mobile network. In the disclosed embodiments, step S2 is intended to determine the specific antenna path or conduction path that caused the mutual interference.

[0027] In the disclosed embodiment, based on the determination of the specific antenna path or conduction path that caused the mutual interference, step S3 can perform targeted anti-mutual interference adjustment that is consistent with the mutual interference, and is intended to reduce or eliminate the mutual interference between the WiFi network and the mobile network by adaptively switching to or adjusting to an interference-free path when mutual interference exists.

[0028] In the terminal network anti-interference coordination method provided by the disclosed embodiments, the terminal can recognize the mutual interference between the mobile network and the WiFi network, determine the specific path where the mutual interference occurs, and thereby perform targeted anti-interference coordination. In this way, the mutual interference between the WiFi network and the mobile network can be reduced or eliminated, and the throughput rate of the terminal under multi-network fusion can be improved. Under multi-network fusion, each WiFi and mobile network band can transmit at full uplink rate and full downlink rate without interference, which is beneficial to improving communication quality under multi-network fusion and improving user experience.

[0029] In the disclosed embodiment, there is no particular limitation on how to determine whether a mobile network and a WiFi network interfere with each other.

[0030] In some embodiments, the presence of mutual interference is determined based on actual operational network signaling measurements.

[0031] Accordingly, in some embodiments, referring to FIG. 2, determining whether the mobile network and the WiFi network interfere with each other includes the following steps S111-S112.

[0032] In step S111, a combined wireless performance parameter of the mobile network and the WiFi network, a first single wireless performance parameter of the mobile network, and a second single wireless performance parameter of the WiFi network are obtained.

[0033] In step S112, the combined wireless performance parameter is compared with the first single wireless performance parameter and the second single wireless performance parameter to determine whether the mobile network and the WiFi network interfere with each other.

[0034] In the disclosed embodiments, the combined wireless performance parameter, the first single wireless performance parameter, and the second single wireless performance parameter are all wireless performance parameters. The disclosed embodiments do not particularly limit the combined wireless performance parameter, the first single wireless performance parameter, and the second single wireless performance parameter. For example, the combined wireless performance parameter may include a combined uplink throughput rate and downlink throughput rate of WiFi and NR, a block error rate (BLER), a signal-to-noise ratio (SNR), etc. The single wireless performance parameters include the respective signal strengths of WiFi or NR (e.g., Received Signal Strength Indication (RSSI), Reference Signal Receiving Power (RSRP)), signal strength under each channel path, throughput rate and block error rate of each channel, current band and antenna usage of WiFi (e.g., 2.4G / 5G / 6G, 1*1MIMO / 2*2MIMO / 4*4MIMO / 8*8MIMO), NR antenna usage (e.g., 1*1MIMO / 2*2MIMO / 4*4MIMO), etc. In some embodiments, wireless performance parameters for multi-network fusion are collected as shown in FIG. 3.

[0035] In the disclosed embodiment, steps S111 to S112 can determine the cause of the interference, thereby determining whether the WiFi network and the mobile network interfere with each other.

[0036] In some embodiments, as shown in FIG. 4, if the multi-network fused data is abnormal, it can be determined whether the abnormality is due to base station influence, router influence, component interference, resource influence, or mutual interference influence. For example, when the multi-network fused data exhibits a throughput abnormality or a large block error rate, a flow for determining mutual interference is initiated. For example, the WiFi-only throughput, the NR-only throughput, and the combined throughput are obtained. The combined throughput is compared with the WiFi-only throughput and the NR-only throughput. If the combined throughput is lower than the WiFi-only throughput or the NR-only throughput, it indicates the presence of mutual interference. Alternatively, the WiFi-only BLER, the NR-only BLER, and the combined BLER are obtained. The combined BLER is compared with the WiFi-only BLER and the NR-only BLER. If the combined BLER is higher than the WiFi-only BLER or the NR-only BLER, it indicates the presence of mutual interference.

[0037] In some embodiments, terminals determine whether they interfere with each other by performing a self transmit / receive test.

[0038] Accordingly, in some embodiments, determining whether the mobile network and the WiFi network interfere with each other includes determining whether the mobile network and the WiFi network interfere with each other by having the mobile network and the WiFi network perform a self transmit / receive test.

[0039] The disclosed embodiment does not particularly limit how the self transmission / reception test is performed.

[0040] In some embodiments, referring to FIG. 5, the step of determining whether the mobile network and the WiFi network interfere with each other by having the mobile network and the WiFi network perform a self-transmission / reception test includes the following steps S121 to S124:

[0041] In step S121, intermediate frequency signals corresponding to a plurality of frequency points are generated.

[0042] In step S122, the first network is controlled to transmit the corresponding intermediate frequency signals at a plurality of frequency points.

[0043] In step S123, when the first network transmits at any frequency point, the second network is controlled to receive in sequence at multiple reference levels, and the multiple reference levels correspond one-to-one to multiple channels of the second network.

[0044] In step S124, it is determined whether the first network interferes with the second network based on the reception level of the second network and a reference level corresponding to the second network.

[0045] Here, the first network is one of the mobile network and the WiFi network, and the second network is another of the mobile network and the WiFi network.

[0046] In the disclosed embodiments, the first network refers to a network acting as an interference source, and the second network refers to a network acting as a receiver of interference. In the disclosed embodiments, the WiFi network can be the interference source and the mobile network can be the receiver of interference, or the mobile network can be the interference source and the WiFi network can be the interference source. The mutual interference determination can include performing full channel interference scanning on NR with WiFi as the interference source, and performing full channel interference scanning on WiFi with NR as the interference source.

[0047] In the disclosed embodiment, the self transmit / receive test can also determine the mutual interference path where mutual interference exists.

[0048] Accordingly, in some embodiments, referring to FIG. 5 , when the mobile network and the WiFi network interfere with each other, the step of determining a mutual interference path along which the mobile network and the WiFi network interfere with each other includes the following step S201:

[0049] In step S201, when the first network interferes with the second network, the mutual interference path is determined based on a frequency point corresponding to the first network and a reference level corresponding to the second network.

[0050] In some embodiments, referring to FIG. 6, determining mutual interference paths along which the mobile network and the WiFi network interfere with each other includes the following steps S211 to S212.

[0051] In step S211, interactions between a plurality of mobile network routes of the mobile network and a plurality of WiFi routes of the WiFi network are tested.

[0052] In step S212, the mobile network routes interfered by the WiFi network and / or the WiFi routes interfered by the mobile network are determined.

[0053] In the disclosed embodiment, testing the interaction between multiple mobile network paths of a mobile network and multiple WiFi paths of a WiFi network can be performed by controlling one of the mobile network and the WiFi network to operate on a certain channel while simultaneously testing interference in each channel of the other. Taking the WiFi network as an example of testing interference in each NR channel by controlling it to operate on a certain channel, as shown in Figure 7, when a certain WiFi antenna transmits, in a certain receive (RX) mode of Primary Receive (PRX), Diversity Receive (DRX), PRX MIMO, or DRX MIMO, the collected values ​​of fusion parameters such as RSRP or Modulation and Coding Scheme (MCS) are tested and compared with the collected values ​​when WiFi is not present, and the NR is controlled to determine whether to decrease the collected values. If it is determined that there is an decrease, it means that there is interference.

[0078] In a third aspect, referring to FIG. 9 , the presently disclosed embodiment provides a computer-readable storage medium having a computer program stored therein, the computer program causing a processor, when executed by the processor, to implement the method for adjusting terminal networks to prevent mutual interference described in the first aspect of the presently disclosed embodiment.

[0079] Hereinafter, in order to enable those skilled in the art to more clearly understand the technical solutions provided by the embodiments of the present disclosure, the technical solutions provided by the embodiments of the present disclosure will be described in detail with specific examples.

[0080] Example 1 FIG. 10 is a schematic diagram of the system structure in this embodiment.

[0081] As shown in Figure 10, the mobile terminal includes a multi-network fusion collection module L1, a mutual interference determination module L2, a mutual interference self-test scanning module L3, a mutual interference path and antenna recognition module L4, a mutual interference prevention control module L5, a path reconstruction module L6, a dynamic length adjustment module L7, a dynamic antenna and ground feed adjustment module L8, a dynamic tank circuit and polarization current adjustment module L9, a dynamic radiation direction adjustment module L10, a dynamic antenna shape adjustment module L11 and a mutual interference module library module L12.

[0082] The multi-network fusion collection module L1 is connected to the mutual interference determination module L2 and the mutual interference prevention control module L5 and is used to collect wireless performance parameters under terminal WiFi 2.4G / 5G / 6G and NR multi-network fusion. The wireless performance parameters include the combined uplink and downlink throughput rates, block error rates, and SNRs of WiFi and NR, the respective WiFi or NR signal strengths (e.g., RSSI, RSRP), the signal strength under each channel path, the throughput rate and block error rate of each channel, the current WiFi band and antenna usage status (e.g., 2.4G / 5G / 6G, 1*1 MIMO / 2*2 MIMO / 4*4 MIMO / 8*8 MIMO), and the NR antenna usage status (e.g., 1*1 MIMO / 2*2 MIMO / 4*4 MIMO). The wireless performance parameters under multi-network fusion are collected as shown in Figure 3.

[0083] The collected values ​​of antenna status and signal quality status can be collected in real time by the mobile phone baseband chip and the connected WiFi chip and NR chip. The antenna status includes the collected values ​​of antenna status of CH0 / CH1 / CHn and multiple MIMO paths.

[0084] The mutual interference determination module L2 is connected to the multi-network fusion collection module L1 and the mutual interference path and antenna recognition module L4, and is used to determine the factors causing the mutual interference, i.e., whether it is due to base station network factors, router factors, component interference, or the related influence between NR and WiFi.

[0085] When the multi-network fusion collection module detects anomalies in throughput and a large block error rate, it triggers a mutual interference detection flow. For example, it detects the throughput of WiFi and NR alone and compares the combined throughput with the single-mode throughput. If the combined throughput is lower than the single-mode throughput, it indicates the presence of mutual interference. Alternatively, it detects the BLER of WiFi and NR alone and compares the combined BLER with the single-mode BLER. If the combined BLER is higher than the single-mode BLER, it indicates the presence of mutual interference.

[0086] The mutual interference self-test scanning module L3 is connected to the mutual interference path and antenna recognition module L4 and the mutual interference prevention control module L5, and is used to realize mutual interference self-transmission and reception tests. The mutual interference judgment module L2 determines whether mutual interference exists by measuring actual network signaling, and since it relies on connected routers and base stations, it is necessary to establish real-time detection of signaling connections. The mutual interference self-test scanning module L3 can inspect and recognize mutual interference signals through the transmission and reception of the 5G terminal itself, without relying on other devices.

[0087] The mutual interference self-test process involves the adaptive self-sensing control module inputting a basic level signal to the mobile phone's front end. The mobile phone passes this signal through a bandpass filter, amplifies it with a low-noise amplifier (LNA), and then mixes it with a variable frequency local oscillator to obtain an intermediate frequency signal corresponding to the band. The intermediate frequency signal undergoes post-filtering and AD conversion before being sent to a variable gain amplifier and then to the level reception, calculation, and reporting module. The LO frequency is continuously adjusted to obtain different intermediate frequency signals, and the reception level values ​​for each frequency point are then collected. After the mutual interference self-test scanning module L3 is turned on, it controls the mobile phone to enter WiFi and NR mutual interference self-scanning mode.

[0088] In some embodiments, the mutual interference self-test program controls the 5G terminal RF chip transmitter and receiver to enter an interference mutual scanning mode, causes the mobile phone to switch to a status in which WiFi and NR operate simultaneously, and performs a self-transmit / receive loop sweep at a specific operating band, bandwidth, and frequency point.

[0089] In Figure 11, WiFi0 and WiFi1 indicate two channels corresponding to each band. As shown in Figure 11, when WiFi interferes with NR, the control flow includes the following steps: (1) Control WiFi as an interference source and NR as an interference-receiving source. (2) Control the WiFi signal to transmit at maximum power, and control the NR to receive the WiFi signal at a set reference level. (3) Configure WiFi to transmit at bandwidth Wn, frequency point Fn, and channel CHn, and perform a full-channel RX interference scan on NR. (4) Reduce the transmission power of the WiFi signal by a specific power step Pstep and perform a full channel scan in NR. (5) Do not stop WiFi power transmission scanning until the NR signal is interference-free. (6) The interference frequency point and the interference power value are stored.

[0090] When NR interferes with WiFi, the control flow includes the following steps: (1) Control NR as an interference source and WiFi as an interference receiver. (2) Control the NR signal to be transmitted at maximum power, and control the WiFi to receive the NR signal at a set reference level. (3) NR is configured to transmit at bandwidth Wn, frequency point Fn, and channel CHn, and a full-channel RX interference scan is performed on WiFi. (4) Reduce the transmission power of the NR signal by a specific power step Pstep and perform a full channel scan on WiFi. (5) Do not stop NR power transmission scanning until the WiFi signal is interference-free. (6) The interference frequency point and the interference power value are stored.

[0091] The mutual interference path and antenna recognition module L4 is connected to the mutual interference judgment module L2, the mutual interference self-test scanning module L3, and the mutual interference prevention control module L5, and is used to recognize and determine the conduction path or antenna path that causes interference by testing the throughput and block error rate of each path and comparing the throughput and block error rate of each path without mutual interference bands.

[0092] When there is mutual interference between WiFi and NR on a terminal, the WiFi is 2.4G, 5G, or 6G and has at least two antennas, such as CH0 and CH1, and the NR also has two or four antennas. However, not all WiFi antennas and NR antennas interfere with each other, and often one antenna or path affects another antenna or path. Therefore, it is necessary to recognize the specific interference and the antenna path that is being interfered with.

[0093] As shown in Figure 7, an example will be described in which the operation of a certain channel of a WiFi network is controlled to test interference with each NR channel. In Figure 7, multiple WiFi antennas are shown as CH1, CH6, CH13, CH36, and CH100, and multiple NR channels are shown as CH1, CH2, ..., CHn. WiFi transmission power corresponds to multiple levels: maximum transmission power (Power_max), medium transmission power (Power_mid), and minimum transmission power (Power_low). When a certain WiFi antenna transmits a signal, in one of the RX modes PRX, DRX, PRX MIMO, and DRX MIMO, the collected values ​​of fusion parameters such as RSRP or MCS are tested and compared with the collected values ​​when WiFi is not present, and NR is controlled to determine whether to decrease them. If they decrease, it means there is interference.

[0094] The mutual interference prevention control module L5 is connected to the path reconstruction module L6, the mutual interference module library module L12, and each mutual interference prevention adjustment module L7 to L11, and by detecting different mutual interference situations, calls the circuit and method for the mutual interference recognition feature parameters to adjust targeted and consistent mutual interference prevention.

[0095] This embodiment proposes various WiFi-NR interference prevention schemes, which can be used individually or two or more can be used simultaneously, and the control is mainly divided into several parts as follows: (1) Dynamic length adjustment: When the antenna length is adjustable, the WiFi or NR antenna length can be changed to change the radiation direction, mutual coupling, current distribution, etc., thereby realizing anti-mutual interference adjustment. (2) Dynamic antenna and ground feed adjustment: When the antenna length cannot be changed and the signal feed point or ground feed point is adjustable, the signal feed point or ground feed point position can be adjusted to select the optimal feed point position with small coupling, thereby reducing antenna interference between WiFi and NR. (3) Dynamic tank circuit adjustment: Changing the shape of the tank circuit on the surface of the WiFi and NR metal antennas, slot antennas, IFAs, and PIFA antennas changes the direction of the original antenna current flow, reducing antenna interference between WiFi and NR. This may be called dynamic current adjustment. For example, if one of the WiFi or NR antennas is an IFA, PIFA, or slot antenna, changing the local wiring shape or copper foil shape of the antenna introduces a new coupling current path, adds a coupling current cancellation path, and changes the original coupling current path. This increases isolation and reduces mutual interference. In other words, changing the current distribution on the antenna surface reduces mutual coupling. (4) Dynamic polarization and current adjustment: If the mutual interference is caused by the antenna polarization directions of WiFi and NR being the same or close to each other, the relative positions of the WiFi and NR antennas can be changed or the antenna configuration can be changed to change the antenna polarization direction between the two to orthogonal directions, thereby reducing the mutual interference. (5) Dynamic radiation direction adjustment: When mutual interference is highly directional, i.e., when there is interference in one direction but weak interference in another direction, the radiation direction of one or two antennas can be changed by adjusting the filtering network on the ground feed point or by changing the positional relationship between the two antennas, thereby reducing the mutual interference. (6) Dynamic Antenna Configuration Adjustment: When interference from a particular antenna configuration is severe and a single antenna configuration cannot resolve the interference, a dynamic antenna configuration adjustment method can be invoked. The WiFi and NR antennas on the mobile phone are configured as multiple parasitic branches. Monopole antennas, slot antennas, IFA antennas, PIFA antennas, loop antennas, and metal-framed antennas are connected in series and parallel using specific circuits, switches, metal shorts, etc. to form multiple antenna combinations, thereby changing the interference between the WiFi and NR antennas. For example, if a mobile phone's WiFi or NR antenna is a metal slot antenna, when strong interference is observed, the antenna configuration can be adjusted by turning the circuit on and off, for example, changing from a slot antenna to a loop antenna. Loop antennas have a closed current path, which allows current to flow in a closed loop, resulting in strong interference prevention performance.

[0096] The path reconstruction module L6 is connected to the mutual interference prevention control module L5 and is used to reconstruct the RF conduction paths or antenna paths of WiFi and NR to solve the mutual interference problem between the two methods.

[0097] In WiFi 6 or WiFi 7, WiFi has 2N antennas, each of which is distributed in different directions, positions, and angles on the terminal. At the same time, 2.4G / 5G / 6G have 2 / 4 / 6 / 8 or more WiFi Front-End Modules (FEMs), and the antennas are connected to the WiFi main chip through these FEMs, forming different WiFi conduction and antenna paths.

[0098] The path reconstruction for preventing WiFi and NR mutual interference includes the reconstruction of the conduction path from the WiFi chip end to multiple FEMs and the reconstruction of the antenna radiation path from the multiple FEMs to multiple WiFi antennas. The WiFi-NR mutual interference path reconstruction can be divided into the following three parts, as shown in Figure 12.

[0099] The first part is the WiFi antenna mutual interference prevention reconstruction. There are 2N antennas distributed above, below, left and right of the mobile phone, and each WiFi antenna corresponds to one WiFi band and one channel. While the conventional solution is relatively independent, here different WiFi antennas are interconnected through a multi-input multi-output switch to form different switching and intercommunication links, realizing antenna path switching.

[0100] The second part is WiFi FEM mutual interference prevention reconstruction. WiFi includes multiple MIMO channels, and each original channel corresponds to one FEM including a power amplifier (PA) and an LNA. Of course, this FEM can include one of the PA / LNAs, or it can include only a filter and a switch without the PA / LNA FEM. The WiFi antenna is connected to the WiFi chip via these FEMs. While the conventional approach is one-to-one, here, multi-input multi-output switches such as DPDT, 3P3T, and 4P4T are used to connect the inputs of these modules to the TX / RX output ports of the WiFi chip, forming an intercommunication state. As long as each FEM corresponds to one antenna, intercommunication and switching between antennas with different orientations can be realized.

[0101] The third part is the NR front-end RF and antenna path mutual interference prevention reconstruction. The NR signal is transmitted from the RF chip and passes through a PA, single-pole double-throw (SPDT) switch, NR filter, coupler, X-band antenna switch (XSW), diplexer / triplexer, and finally to the NR main transmit antenna. The terminal receives the signal from the base station via the main receive antenna and passes it through a divider, XSW switch, NR filter, and LNA in that order before finally reaching the RF chip. The XSW switch can include a DPDT, 3P3T, or 4P4T switch. Taking the N78 as an example, this is further divided into four paths: PRX / DRX / PRX MIMO / DRX MIMO, corresponding to the four antennas ANT1, ANT2, ANT3, and ANT4. In actual operation, these paths can be switched between depending on the interference situation to avoid interfering RF or antenna paths.

[0102] The dynamic length adjustment module L7 is connected to the mutual interference prevention control module L5 and is used to realize mutual interference prevention adjustment based on dynamic length change. When interference between WiFi and NR is detected, if WiFi interferes with NR, the length of the WiFi antenna can be changed to reduce the mutual interference ability, or the length of the NR antenna can be changed to reduce the coupling of WiFi to NR.

[0103] As shown in Figure 13, S1 is a WiFi 5G antenna, and S5 is an N78 antenna. When mutual interference occurs between WiFi and N78, S1 can be extended to S2, S3, and S4 using a switch. The mutual interference control module detects the mutual interference situation between the two antennas, WiFi 5G and N78, in real time. When interference occurs, the mutual interference control module controls the SPNT switch to extend S1 to, for example, S2 and S3, changing the antenna length to change the radiation direction and the direction of surface current flow, thereby reducing the mutual coupling with N78.

[0104] As shown in Figure 13, S1 is a WiFi 5G antenna, and S5 is an N78 antenna. When mutual interference occurs between WiFi and N78, S1 can be extended to S2, S3, and S4 through a switch, and the mutual interference control module detects the mutual interference situation between the two antennas, WiFi 5G and N78, in real time. When interference occurs, the mutual interference control module controls the SPNT switch to extend S1, for example, to S1S2, S1S3, and S1S4. By changing the antenna length, the radiation direction and the surface current flow direction are changed, thereby reducing the mutual coupling with N78.

[0105] Also, as shown in Figure 14, S1 can be extended to S1S2, S1S2S3, and S1S2S3S4 using multiple SP2T switches, and by changing the antenna length, the radiation direction and the direction in which the surface current flows can be changed, thereby reducing the mutual coupling with N78.

[0106] The dynamic antenna and ground feed adjustment module L8 is connected to the mutual interference prevention control module L5 and is used to realize mutual interference prevention adjustment based on the dynamic antenna and ground feed. As shown in Figures 15 and 16, multiple ground points A, B, C, D, and E are added between the metal frame and the main board. As shown in Figure 15, the dynamic antenna and ground feed are adjusted by an SP5T switch, and as shown in Figure 16, the dynamic antenna and ground feed are adjusted by a multiplexer (MUX).

[0107] The dynamic tank circuit and polarization current adjustment module L9 is connected to the anti-mutual interference control module L5 and is used to implement anti-mutual interference adjustment based on dynamic antenna tank circuits or polarization currents. By changing the shape of the tank circuits on the surfaces of WiFi and NR metal antennas, slot antennas, IFAs, and PIFA antennas, the direction of the original antenna currents is changed, reducing antenna mutual interference between WiFi and NR. This may be referred to as dynamic current adjustment. For example, if one of the WiFi or NR antennas is an IFA, PIFA, or slot antenna, changing the local wiring shape or copper foil shape of the antenna introduces a new coupling current path, adds a coupling current cancellation path, and changes the original coupling current path. This increases isolation and reduces mutual interference. In other words, changing the current distribution on the antenna surface reduces mutual coupling.

[0108] Taking FIG. 17 as an example, there may be two operation modes:

[0109] Solution 1: When the WiFi antenna strongly interferes with NR antenna 1 or NR antenna 2, the WiFi antenna changes the shape of the tank circuit by turning on / off switches S1 to S5, thereby changing the direction of current flow.

[0110] In principle, when NR antenna 1 or 2 and the WiFi antenna interfere with each other, a switch changes the tank circuit direction so that the surface polarization current of the WiFi antenna is perpendicular to the polarization current direction of NR antenna 1 or 2, avoiding parallelism, thereby reducing mutual coupling. If it is determined that the antenna currently causing interference is NR antenna 1, B1B2, B1B2B6, or B1B4 is selected as the available WiFi antenna path. If it is determined that the antenna currently causing interference is NR antenna 2, B1, B1B2B3B4, or B1B2B5B6 is selected as the available WiFi antenna path. The above paths form a mapping table, and the control module selects the optimal adjustment path according to the specific interfering antenna and scenario.

[0111] Solution 2: When two antennas interfere with each other, the length of the LDS or metal antenna can be changed by turning the tank circuit on or off, thereby reducing interference. If NR antenna 1 is originally A4, which strongly interferes with WiFi, turning off switch S8 changes it to antenna A3. If A3 still interferes, it can be further backed off to antenna A2 or A1. During this process, the antenna matching or tuning circuit is subsequently adjusted, thereby avoiding frequency deviation of the NR antenna. Solution 2 reduces the area of ​​the antenna tank circuit, thereby reducing the impact on WiFi.

[0112] The dynamic radiation direction adjustment module L10 is connected to the mutual interference prevention control module L5 and is used to realize dynamic adjustment of mutual interference prevention based on radiation direction. As a dynamic radiation direction adjustment method, when the mutual interference has strong directionality, that is, when there is interference in one direction but not in another, it can be determined that the mutual coupling effect is caused by the radiation direction effect, and at this time, the radiation direction map of one or two of the antennas is changed to reduce the mutual interference effect.

[0113] If mutual interference between the WiFi and NR antennas is detected, a method for adjusting the direction map can be achieved by adding matching network components or decoupling / filtering network components to the ground feed points of the two antennas, or by adding antenna direction map change branches. For example, the antenna direction can be divided into different sections and segments by slots on the metal frame of the terminal. Each section corresponds to one antenna direction, with the lower-left segment corresponding to the lower-left direction and the upper-right segment corresponding to the upper-right direction. Variable direction map change components can also adjust the direction map on the ground feed point using SP4T tuning switches or MEMS tuning switches. Matching network components and decoupling / filtering network components on the master signal feed point path can also be used to adjust the direction map radiation direction by turning on and off these different architectures and changing the RLC values ​​(resistance, capacitance, and inductance values) to change the maximum gain direction. As shown in Figure 18, the dynamic direction map for preventing WiFi-NR mutual interference can be adjusted.

[0114] The dynamic antenna configuration adjustment module L11 is connected to the mutual interference prevention control module L5 and is used to adjust mutual interference based on dynamic antenna configuration. When interference from a certain antenna configuration is large and a single antenna configuration cannot resolve the mutual interference, a dynamic antenna configuration adjustment method can be invoked to configure the WiFi and NR antennas on the mobile phone into multiple parasitic branches, and to connect monopole antennas, slot antennas, IFA antennas, PIFA antennas, LOOP antennas, and metal-framed antennas in series and parallel using specific circuits, switches, metal shorts, etc. to form multiple antenna combinations, thereby changing the mutual interference between the WiFi and NR antennas.

[0115] For example, if a mobile phone's WiFi or NR antenna is originally a metal slot antenna, when strong interference is observed, the antenna configuration can be adjusted by turning the circuit on and off, for example, changing it from a slot antenna to a loop antenna. Loop antennas have a closed current path, allowing the current to flow in a closed loop, resulting in strong interference prevention performance. As shown in Figure 19, the antenna configuration is dynamically adjusted to prevent WiFi-NR interference.

[0116] Example 2 In this embodiment, the operation flow of the dynamic WiFi interference prevention 5G terminal includes the following steps:

[0117] After the terminal system turns on the coordination mode, the control module controls the 5G terminal to enter a WiFi dynamic anti-interference coordination operation status.

[0118] The terminal collects wireless performance parameters under multi-network convergence of WiFi 2.4G / 5G / 6G and NR.

[0119] If the WiFi-NR multi-network convergence network performance fails to meet the threshold requirements, determine the mutual interference factors.

[0120] The mutual interference path and antenna recognition module recognizes the conduction paths or antenna paths that cause interference.

[0121] The mutual interference prevention control module detects different mutual interference scenarios, and the mutual interference recognition feature parameters invoke targeted and coordinated mutual interference prevention adjustment circuits and methods.

[0122] The control module performs direction mapping calculation based on different sensing results and selects the optimal control adjustment strategy.

[0123] If the interference is related to the WiFi and NRRF conduction path or antenna path, the path reconstruction module is turned on to achieve mutual interference prevention.

[0124] If the antenna length is adjustable, the dynamic length adjustment module is turned on to achieve mutual interference prevention.

[0125] If the antenna signal feed point or ground feed point is adjustable, the dynamic antenna and ground feed adjustment module is turned on to achieve mutual interference prevention.

[0126] If the mutual interference is caused by current polarization, the dynamic tank circuit and the polarization current adjustment module are turned on to achieve mutual interference prevention.

[0127] If the mutual interference is caused by the radiation direction, the dynamic radiation direction adjustment module is turned on to prevent mutual interference.

[0128] If the mutual interference is caused by the antenna configuration, the dynamic antenna configuration adjustment module is turned on to prevent the mutual interference.

[0129] The multi-network convergence mutual interference prevention device dynamically detects the throughput situation in real time, and uses the above one or several adjustment methods in real time to adjust in combination until the multi-network convergence performance threshold requirement of the device is consistently met.
