[0002] With the development of wireless communication technology, 5G+WiFi products have appeared on the market. These products support NR / LTE network standards and 2.4G / 5.8G dual-band WiFi AP functions. Accordingly, these products can convert cellular network data into WiFi and wired network data.

[0003] Because these terminals have multiple radio transceivers, different types of radio signals sent and received by these terminals may interfere with each other. That is, the signal transmitted within the frequency band of one type of radio signal may interfere with the received signal of another type of radio signal with a similar frequency.

[0004] Current solutions typically involve adding filters to hardware or increasing the isolation between antennas to prevent multiple radio signals from coexisting in a mutually exclusive manner. This approach is costly and fails to address the interference issues inherent in high-frequency, wide-bandwidth radio signals.

[0042] The coordination method for radio signal interference of terminal devices disclosed in the present invention can be applied to terminal devices, which can be mobile terminals, such as mobile phones, tablet computers, portable WiFi, and other hardware devices with various operating systems.

[0043] The terminal device can transmit and receive first radio signals (5G signals) and second radio signals (WiFi signals). In this disclosure, the first radio signals include 5G signals, and the second radio signals include WiFi signals. The disclosure will be described in detail below in combination with 5G signals and WiFi signals.

[0044] The operating frequency band of the first radio signals includes a first type of frequency band and a second type of frequency band, and the operating channel of the second radio signals includes a first type of channel and a second type of channel. The first type of frequency band is a frequency band that is prone to interference with the second radio signals. Specifically, when the second radio signals are WiFi 2.4G, the first type of frequency band includes (is) the n41 frequency band; when the second radio signals are WiFi 5G, the first type of frequency band includes (is) the n79 frequency band; and when the second radio signals are a mixed signal of WiFi 2.4G and 5G, the first type of frequency band includes (is) n41 and n79. Moreover, when the terminal device is a personal WiFi device, the type of the second radio signals transmitted outward can be selected, that is, the type of the second radio signals transmitted outward, WiFi 2.4G or WiFi 5G, or a mixed signal of the two, can be selected by a control button, so that the content of the first type of frequency band can be confirmed.

[0045] In other words, in the 5G frequency band, the first type of frequency band includes frequency bands close to the frequency of the WiFi signal, such as n41 and n79, etc.; correspondingly, the second type of frequency band is a frequency band that is not prone to interference, such as n1, n2, n3, n5, n7, etc., that is, other frequency bands except the n41 and / or n79 frequency bands (that is, except the first type of channel).

[0046] Similarly, the first type of channel is a channel that is prone to interference, that is, a channel with a center frequency close to n41 or n79; correspondingly, the second type of channel is a channel other than the first type of channel.

[0047] The following will be described in combination with Figures 1 to 4 The coordination method for radio signal interference of a terminal device and the terminal device of the present disclosure will be described in detail.

[0048] Figure 1 is a flowchart of a coordination method for radio signal interference of a terminal device according to an embodiment of the present disclosure.

[0049] Reference Figure 1 The present disclosure provides a coordination method for radio signal interference of a terminal device, which comprises:

[0050] S110. Connect the terminal device to the base station via a first radio signal, obtain the frequency band of the first radio signal, and determine whether the frequency band belongs to a first type of frequency band; S120. When the frequency band of the first radio signal belongs to the first type of frequency band, reconnect the terminal device to the base station, and when reconnecting the terminal device to the base station, maintain priority connection to the second type of frequency band, and determine whether the current frequency band of the first radio signal connecting the terminal device to the base station belongs to the first type of frequency band; S130. When the current frequency band of the first radio signal belongs to the first type of frequency band, determine whether the center frequency of the working channel of the second radio signal is within the working frequency band of the first radio signal, or is close to the working frequency band of the first radio signal; and S140. When the center frequency of the working channel of the second radio signal is within the working frequency band of the first radio signal, or is close to the working frequency band of the first radio signal, perform channel hopping of the second radio signal, and make the center frequency of the working channel of the second radio signal away from the working frequency band of the first radio signal.

[0051] Therefore, the radio signal interference coordination method for terminal devices disclosed in the present invention, based on the existing hardware design of the terminal device, coordinates the interference between multiple radio signals in the same terminal device through software system control methods, which can improve the spectrum usage range and scenarios of the terminal device.

[0052] Specifically, in S110, when the terminal device of the present disclosure is in use, that is, after the system is started, it searches for and connects to the 5G network, thereby enabling the terminal device to connect to the base station via the first radio signal. After the terminal device is connected to the base station, the frequency band of the first radio signal is obtained and it is determined whether the frequency band belongs to the n41 / n79 frequency band.

[0053] On the one hand, when the frequency band does not belong to the n41 / n79 frequency band, the coordination method for radio signal interference of the terminal device disclosed in the present invention is terminated.

[0054] On the other hand, in S120, when the frequency band of the first radio signal belongs to the n41 / n79 frequency band, the historical frequency band is deleted and the terminal device is reconnected to the base station. When reconnecting the terminal device to the base station, the second type of frequency band is preferentially connected, that is, the terminal device is preferentially registered in the interference-free frequency band.

[0055] When the terminal device is connected with the base station again, the current frequency band of the first radio signal is acquired, and it is determined whether the current frequency band of the first radio signal connected with the terminal device and the base station belongs to the first type of frequency band. That is, it is necessary to determine whether the terminal device has successfully registered the non-interference frequency band network outside n41 / n79 at this time. When the current frequency band of the first radio signal belongs to the second type of frequency band, it indicates that the terminal device of the present disclosure will not cause the interference problem of the first radio signal and the second radio signal when running, and the method for coordinating the radio signal interference of the terminal device of the present disclosure is terminated at this time.

[0056] On the other hand, when the current frequency band of the first radio signal still belongs to the first type of frequency band, it indicates that the operation mode of changing the frequency band of the first radio signal has failed, and other technical means are needed to solve the interference problem of the first radio signal and the second radio signal.

[0057] Specifically, in S130, it is necessary to determine whether the working channel of the second radio signal belongs to the first type of channel; that is, whether the center frequency of the working channel of the second radio signal is within the working frequency band of the first radio signal, or close to the working frequency band of the first radio signal; and decide the operation mode according to the determination result.

[0058] On the one hand, when the working channel of the second radio signal does not belong to the first type of channel, that is, the working channel of the second radio signal belongs to the second type of channel, it indicates that the center frequency of the working channel of the second radio signal is far away from the working frequency band of the first radio signal, that is, there will be no interference between the first radio signal and the second radio signal, and at this time, the method for coordinating the radio signal interference of the terminal device of the present disclosure will be terminated.

[0059] On the other hand, when the working channel of the second radio signal belongs to the first type of channel, that is, the center frequency of the working channel of the second radio signal is within the working frequency band of the first radio signal, or close to the working frequency band of the first radio signal, the channel hopping of the second radio signal is performed, and the center frequency of the working channel of the second radio signal is made to be far away from the working frequency band of the first radio signal, that is, the working channel of the second radio signal is changed to the second type of channel.

[0060] More preferably, when the operating frequency band of the first radio signal is n41 and the second radio signal is WiFi 2.4G, channel hopping of the second radio signal is performed, and the channel of the second radio signal is hopped to a low-frequency channel without interference; in this case, when the second radio signal is WiFi 5G, channel hopping of the second radio signal does not need to be performed. When the operating frequency band of the first radio signal is n79 and the second radio signal is WiFi 5G, channel hopping of the second radio signal is performed, and the channel of the second radio signal is hopped to a low-frequency channel without interference; in this case, when the second radio signal is WiFi 2.4G, channel hopping of the second radio signal is not performed.

[0061] That is to say, after the operating frequency band of the first radio signal is determined, the channel hopping of the second radio signal is performed only when the center frequency of the channel of the second radio signal is within the operating frequency band of the first radio signal or close to the operating frequency band of the first radio signal.

[0062] Figure 2 is a flowchart of a method for coordinating radio signal interference of a terminal device according to another embodiment of the present disclosure.

[0063] like Figure 2As shown, the present disclosure provides a coordination method for radio signal interference of a terminal device, including: S110, connecting the terminal device to the base station through a first radio signal, obtaining the frequency band of the first radio signal, and judging whether the frequency band belongs to a first type of frequency band; S120, when the frequency band of the first radio signal belongs to the first type of frequency band, reconnecting the terminal device to the base station, and when reconnecting the terminal device to the base station, maintaining priority connection to the second type of frequency band, and judging whether the current frequency band of the first radio signal connecting the terminal device to the base station belongs to the first type of frequency band; S130, when the current frequency band of the first radio signal belongs to the first type of frequency band, judging whether the center frequency of the working channel of the second radio signal is within the working frequency band of the first radio signal. , or close to the working frequency band of the first radio signal; S140, when the center frequency of the working channel of the second radio signal is within the working frequency band of the first radio signal, or close to the working frequency band of the first radio signal, perform channel hopping of the second radio signal, and make the center frequency of the working channel of the second radio signal away from the working frequency band of the first radio signal; and S150, obtain the signal to interference plus noise ratio and the reference signal received power of the first radio signal and the second radio signal, and determine whether there is interference between the first radio signal and the second radio signal according to the signal to interference plus noise ratio and the reference signal received power, and when there is interference between the first radio signal and the second radio signal, reduce the transmission power of the second radio signal.

[0064] That is to say, when the terminal device disclosed herein is in use, the main reason for the interference is that the frequencies of the first radio signal and the second radio signal are similar. However, when the filtering performance of the filter and other components of the terminal device is certain, even if the frequencies of the first radio signal and the second radio signal differ greatly, there may still be interference between the first radio signal and the second radio signal. Therefore, after the jump of the working channel of the second radio signal is completed, it is necessary to determine whether the interference problem between the first radio signal and the second radio signal has been resolved.

[0065] Specifically, a signal-to-interference-plus-noise ratio (SINR) and a reference signal received power (RSRP) of a first radio signal and a second radio signal are first obtained, and then, based on the SINR and RSRP, a determination is made as to whether interference exists between the first radio signal and the second radio signal. If it is determined that no interference exists between the first radio signal and the second radio signal, the radio signal interference coordination method for a terminal device of the present disclosure terminates.

[0066] More specifically, when the signal to interference plus noise ratio of at least one of the first radio signal and the second radio signal is less than a preset value, and the reference signal receiving power of at least one of the first radio signal and / or the second radio signal is greater than or equal to a preset threshold, it is determined that there is interference between the first radio signal and the second radio signal; otherwise, it is determined that there is no interference between the first radio signal and the second radio signal.

[0067] In a specific embodiment, interference is determined to be present when the sinr of the first radio signal is less than 0 dB, the bit error rate is greater than 90%, the RSRP is greater than -110 dBm, and the sinr of the second radio signal is less than 5 dB, and the RSSI value is greater than -90 dBm. Furthermore, the interference parameter values ​​under different conditions may vary depending on the situation.

[0068] That is, in the process of determining whether there is interference between the first radio signal and the second radio signal, the bit error rate of the first radio signal and / or the second radio signal may also be used as one of the indicators.

[0069] On the other hand, when it is determined that the first radio signal and the second radio signal interfere with each other, the transmission power of the second radio signal is reduced to reduce the interference of the second radio signal on the first radio signal.

[0070] For example, the transmission power of the second radio signal can be reduced by lowering the upper limit of the transmission power of the second radio signal. More preferably, in the process of reducing the transmission power of the second radio signal, the transmission power of the second radio signal can be set to multiple gears. For example, the maximum transmission power of the second radio signal is MAX1, and the upper limit of the transmission power of the second radio signal can be set to MAX1-3dB\MAX1-6dB\MAX1-9dB. Each time the upper limit of the transmission power of the second radio signal is lowered, it is necessary to determine whether there is still interference between the first radio signal and the second radio signal; when there is no interference between the first radio signal and the second radio signal, the upper limit of the transmission power of the second radio signal will no longer be lowered to ensure smooth network connection when connected through the second radio signal.

[0071] That is to say, by lowering the transmission power upper limit of the second radio signal, the interference of WiFi's TX (transmit signal) to 5G's RX (receive signal) can be reduced, thereby reducing the interference between the first radio signal and the second radio signal.

[0072] In the present disclosure, when the transmission power upper limit of the second radio signal is reduced to the minimum transmission power upper limit, it is necessary to further determine whether there is interference between the first radio signal and the second radio signal. Specifically, Figure 3As shown, the coordination method for radio signal interference of a terminal device disclosed in the present invention also includes: S160, judging the signal to interference plus noise ratio and the reference signal receiving power of the first radio signal and the second radio signal, and judging whether there is interference between the first radio signal and the second radio signal based on the signal to interference plus noise ratio and the reference signal receiving power, and when there is interference between the first radio signal and the second radio signal, reducing the transmission power of the first radio signal.

[0073] In S160 , when there is no interference between the first radio signal and the second radio signal, the method for coordinating radio signal interference of a terminal device of the present disclosure is terminated.

[0074] In the present disclosure, reducing the transmission power of the first radio signal includes: lowering the transmission power upper limit of the first radio signal, that is, performing 5G power backoff control, thereby reducing 5G Sub6 TX interference with WiFi RX, that is, reducing the interference of the first radio signal on the second radio signal.

[0075] More preferably, in the process of reducing the transmission power of the first radio signal, the transmission power of the first radio signal can be set to multiple gears. For example, the maximum transmission power of the first radio signal is MAX2, and the transmission power upper limit of the first radio signal can be set to MAX2-3dB\MAX2-6dB\MAX2-9dB, and each time the transmission power upper limit of the first radio signal is lowered, it is necessary to determine whether there is still interference between the first radio signal and the second radio signal; when there is no interference between the first radio signal and the second radio signal, the transmission power upper limit of the first radio signal will no longer be lowered to ensure that the network is unobstructed when connected through the first radio signal.

[0076] In the present disclosure, when the transmission power upper limit of the first radio signal is reduced to the minimum transmission power upper limit, it is necessary to further determine whether there is interference between the first radio signal and the second radio signal. Specifically, Figure 4 As shown, the coordination method for radio signal interference of a terminal device disclosed in the present invention also includes: S170, judging the signal to interference plus noise ratio and the reference signal receiving power of the first radio signal and the second radio signal, and judging whether there is interference between the first radio signal and the second radio signal based on the signal to interference plus noise ratio and the reference signal receiving power, and when there is interference between the first radio signal and the second radio signal, performing time division multiplexing control of the first radio signal and the second radio signal.

[0077] That is to say, by performing time-division multiplexing control of the first radio signal and the second radio signal, only one of WiFi and 5G sub6 can be allowed to work at the same time, thereby avoiding coexistence interference problems.

[0078] In one specific embodiment, time-division multiplexing control of the first radio signal and the second radio signal includes the following operation cycle: C1: allowing transmission and reception of the first radio signal, but not allowing transmission and reception of the second radio signal, during a first preset time; and C2: allowing reception of the first radio signal, and allowing transmission and reception of the second radio signal, during a second preset time. More preferably, step C2 can be configured to: not allowing transmission and reception of the first radio signal, but allowing transmission and reception of the second radio signal, during the second preset time, thereby achieving complete time-division multiplexing control.

[0079] In a specific embodiment, the first preset time and the second preset time may adopt the same value, for example, 100 ms, thereby solving the interference problem between the first radio signal and the second radio signal through time division multiplexing control.

[0080] In the present disclosure, after executing the time-division multiplexing control of the first radio signal and the second radio signal, it is possible to further determine whether interference exists between the first radio signal and the second radio signal, and perform further processing based on the determination result. Specifically, when there is no interference between the first radio signal and the second radio signal, the coordination method for radio signal interference of a terminal device disclosed in the present disclosure will terminate execution. On the other hand, when there is still interference between the first radio signal and the second radio signal, the step S110 can be jumped to eliminate the interference again. Accordingly, when the number of executions of the coordination method for radio signal interference of a terminal device disclosed in the present disclosure reaches a preset threshold number, and the interference between the first radio signal and the second radio signal still exists, the execution of the coordination method for radio signal interference of a terminal device disclosed in the present disclosure is terminated. Figure 5 The figure is an overall flow chart of a method for coordinating radio signal interference of terminal devices according to one embodiment of the present disclosure.

[0081] In general, the flowchart of the method for coordinating radio signal interference of terminal equipment disclosed in the present invention is as follows: Figure 5 As shown, by applying the disclosed coordination method for radio signal interference of terminal devices to existing devices, it is also possible to solve the problem that the original hardware design solution cannot solve the interference problem between WiFi and 5G Sub6, and the terminal devices cannot be used normally or can only be used in exclusive manner, and enable these devices to be used normally in the interference frequency band, thereby improving the scope and scenarios of use of the equipment.

[0083] like Figure 6 and Figure 7 As shown, since the frequency band interval between the n41 band and the 2.4GHz WLAN band is only 12MHz, and the frequency band interval between the n79 band and the 5G WLAN band is 150MHz, interference is easily generated between the two signals. This disclosure addresses this problem by proposing a software solution and achieving better technical results.
