[0085] In the description of the embodiments of the present application, the term "corresponding" can represent a direct or indirect relationship between the two, or an associated relationship between the two, or an indication and being indicated, configuration and being configured, etc.

[0086] In order to facilitate understanding of the technical solutions of the embodiments of the present application, the related technologies of the embodiments of the present application are described below. The following related technologies can be combined with the technical solutions of the embodiments of the present application in any way, and all belong to the protection scope of the embodiments of the present application.

[0087] (I) Wireless transceiver system in terminal

[0088] Generally, a terminal has multiple wireless transceiver systems inside. For example, as shown in Figure 2 , the terminal can include a wireless transceiver system (hereinafter referred to as a mobile communication unit) for second-generation communication (2th-Generation, 2G), third-generation communication (3th-Generation, 3G), fourth-generation communication (4th-Generation, 4G), fifth-generation communication (5th-Generation, 5G), etc. It can also include other wireless transceiver systems for license-exempt communication, such as a WiFi communication unit, a Bluetooth communication unit, a Global Positioning System (GPS), etc.

[0089] For mobile communication units, the terminal needs to communicate with the base station, and the base station schedules the terminal to receive and transmit on certain wireless resources. The terminal needs to follow the scheduling of the base station in this process.

[0090] For communication units working in the license-exempt spectrum, such as WiFi, Bluetooth, etc., the terminal autonomously selects an idle wireless resource to initiate communication with the opposite terminal.

[0091] In addition, in some emerging applications such as D2D or V2X, the UE can communicate directly with other UEs without going through the base station. This direct communication mode between UEs is called sidelink (SL) communication. The feature of such communication is that the base station is no longer the control center, and direct communication can be carried out without the network. In certain cases, the terminal can autonomously select the idle resource to initiate the sidelink communication without the scheduling of the base station. For example, in the case of vehicle networking, vehicles can communicate with nearby vehicles to carry out anti-collision warning and other applications. Figure 3

[0092] (II) Interference and sensitivity backoff in mobile communication system

[0093] Receiver sensitivity backoff refers to the fact that the receiver of the terminal is affected by interference or noise and other factors, resulting in a certain deterioration of the receiver sensitivity. In NR, there are many cases that cause sensitivity backoff, and the typical one is the sensitivity backoff caused by harmonic or intermodulation interference under EN-DC, NE-DC, DC or inter-band CA. The following will take EN-DC as an example to briefly introduce it.

[0094] Generally, the main source of inter-interference in the terminal is the nonlinearity of the radio frequency front-end devices such as power amplifier (PA) and the like. When the input is a single-tone signal cos(ωt), the output signal contains 2ωt, 3ωt and other high-order harmonic components. When the harmonic falls into the receiving frequency band, it causes harmonic interference. This interference often occurs in the scenario where low-frequency transmission and high-frequency reception are carried out at the same time.

[0095] When the input signal contains multiple frequency components, the output contains the intermodulation products of each order of these frequency components. For example, when the input contains two frequency components cos(ω1t) and cos(ω2t), the output will contain second-order intermodulation (ω1±ω2), third-order intermodulation (2ω1±ω2, ω1±2ω2) and the like. When the intermodulation product falls into the receiving frequency band, it causes intermodulation interference. This interference often occurs in the scenario where high and low frequencies are transmitted at the same time, external signals are poured into the UE transmission link and the like.

[0096] For example, as shown in Figure 4 , the second harmonic of the B3 uplink will cause second harmonic interference to the n77 downlink. The second-order intermodulation product of the B3 uplink and the n77 uplink will cause interference to the downlink reception of B3. The specific interference is shown in Figure 5 and Figure 6 .

[0097] ​The above harmonic and intermodulation interference has a serious impact on the receiving performance of the terminal in NR, and the impact of the second harmonic and the second-order intermodulation product is more likely to reach tens of dB (decibels) of sensitivity degradation. This results in a significant contraction of the downlink receiving coverage of the terminal, as shown in Figure 7 In the standard, a definition of sensitivity backoff is usually adopted to be compatible with different interference, that is, MSD (Maximum Sensitivity Degradation), which represents the allowed degradation value of the downlink receiving capability of the terminal for the frequency band combination with interference.

[0098] In addition to the above inter-band harmonic and intermodulation interference, when the operating frequency bands are close to each other, inter-band leakage interference may also occur, as shown in Figure 8 When the receiving frequency spectrum of frequency band B and the transmitting frequency spectrum of frequency band A are close to each other, interference will also occur.

[0099] The above inter-interference in the mobile communication system also occurs between multiple wireless transceiver systems of the terminal. However, the difference is that, within the mobile communication system, since the base station is used as the central control node, the receiving and transmitting between multiple carriers can be scheduled, so as to solve the inter-interference between carriers to a certain extent. However, for the interference between multiple wireless transceiver systems, since there is a lack of coordination of the base station, once the interference occurs, it will directly lead to a serious decline in the performance of the interfered system. Moreover, since the multiple wireless transceiver systems in the terminal device are independent of each other, for example, the 5G communication unit and the WiFi communication unit are independent of each other, it is difficult to eliminate or avoid the interference.

[0100] The scheme provided by the embodiments of the present application is mainly used to solve at least one of the above problems.

[0101] In order to enable a more detailed understanding of the features and technical contents of the embodiments of the present application, the implementation of the embodiments of the present application will be described in detail below with reference to the accompanying drawings, which are only used for reference and do not limit the embodiments of the present application.

[0102] Figure 9 is a schematic flowchart of a frequency information processing method according to an embodiment of the present application. The method comprises:

[0103] S110, the first communication unit in the terminal device receives first resource information from the second communication unit in the terminal device; wherein the first resource information comprises working frequency information of the second communication unit, and the working frequency information of the second communication unit is used to determine the working frequency information of the first communication unit.

[0104] The above method can be applied to the terminal shown in Figure 2 but is not limited thereto.

[0105] In the embodiments of the present application, the communication unit can be the wireless transceiving system described above. For example, the communication unit can include a mobile communication unit for 2G, 3G, 4G or 5G mobile communication, and can also include a WiFi communication unit, a Bluetooth communication unit, a SL communication unit and other license-free communication units.

[0106] Optionally, the first communication unit includes a first mobile communication unit and / or a first license-free communication unit.

[0107] Optionally, the second communication unit includes a second mobile communication unit and / or a second license-free communication unit.

[0108] For example, the first communication unit and the second communication unit can be one mobile communication unit and the other license-free communication unit. That is, the above method can be used for interference coordination between 2G / 3G / 4G mobile communication units and WiFi / Bluetooth / SL communication units.

[0109] For example, the first communication unit and the second communication unit can be one mobile communication unit and the other license-free communication unit. That is, the above method can be used for interference coordination between 2G / 3G / 4G mobile communication units and WiFi / Bluetooth / SL communication units.

[0110] Corresponding to the above method, the second communication unit in the terminal device sends the first resource information to the first communication unit. Specifically, another embodiment of the present application also provides a frequency information processing method, as shown in Figure 10 The method includes:

[0111] S210, the second communication unit in the terminal device sends the first resource information to the first communication unit in the terminal device; wherein the first resource information includes the working frequency information of the second communication unit, and the working frequency information of the second communication unit is used to determine the working frequency information of the first communication unit.

[0112] As described above, the mutual interference between the carriers is related to the frequency at which the carriers are located. These interferences not only occur within the communication unit, but also occur between multiple communication units, such as between a 5G communication unit and a WiFi communication unit. According to the above method of the embodiments of the present application, the first communication unit receives the working frequency information of the second communication unit, and the working frequency information of the first communication unit can be determined based on the working frequency information of the second communication unit. Based on this, the first communication unit can work at a frequency that is not interfered. That is, by performing frequency coordination between the first communication unit and the second communication unit in the terminal device, the interference between the first communication unit and the second communication unit is avoided, and the communication performance can be guaranteed.

[0113] Optionally, a coordination unit can be introduced between the first communication unit and the second communication unit to communicate information and coordinate resources. For example, a separate coordination unit is provided in the terminal device and connected between the first communication unit and the second communication unit. Alternatively, the coordination unit is provided in the first communication unit or the second communication unit. For example, as shown in Figure 11 , a coordination unit can be introduced between the 5G communication system and the WiFi communication system to interact information between the 5G communication unit and the WiFi communication unit, or the functions of the coordination unit can also be included in the 5G communication unit or the WiFi communication unit. Based on this, the process of transmitting and receiving the first resource information between the first communication unit and the second communication unit can be realized through the coordination unit.

[0114] Specifically, the step S110 that the first communication unit in the terminal device receives the first resource information from the second communication unit in the terminal device includes: the first communication unit receives the first resource information from the second communication unit through the coordination unit in the terminal device. That is, the first communication unit can receive the first resource information sent by the coordination unit, which is sent to the coordination unit by the second communication unit.

[0115] Correspondingly, the step S210 that the second communication unit in the terminal device sends the first resource information to the first communication unit in the terminal device includes: the second communication unit sends the first resource information to the first communication unit through the coordination unit in the terminal device. That is, the second communication unit can send the first resource information to the coordination unit, so that the coordination unit sends the first resource information to the first communication unit.

[0116] As shown in Figure 12 , the embodiment of the present application further provides a frequency information processing method, which comprises:

[0117] S310, the coordination unit in the terminal device sends the first resource information to the first communication unit in the terminal device in the case that the first resource information from the second communication unit in the terminal device is received;

[0118] The first resource information comprises the working frequency information of the second communication unit, and the working frequency information of the second communication unit is used to determine the working frequency information of the first communication unit.

[0119] Optionally, for the first communication unit, the frequency information processing method can further comprise:

[0120] The first communication unit determines the frequency information to be avoided based on the working frequency information of the second communication unit, wherein the frequency information to be avoided is not used as the working frequency information of the first communication unit.

[0121] Exemplarily, the frequency information to be avoided can comprise the interfered frequency information. The frequency information to be avoided can be determined based on a relationship between the operating frequency information of the second communication unit and the interfered frequency information.

[0122] For example, the harmonic interference is the influence of the multiple of the interfering carrier frequency on the interfered carrier frequency, the intermodulation interference involves the sum / difference frequency among multiple interfering carrier frequencies, and the adjacent band leakage interference is the influence caused by insufficient frequency band isolation. Accordingly, the frequency information to be avoided can comprise at least one of the following: the multiple of the operating frequency information of the second communication unit, the sum / difference frequency of multiple operating frequency information of the second communication unit, and the frequency information having an isolation less than a preset threshold from the operating frequency information of the second communication unit.

[0123] Optionally, the second communication unit can further send corresponding time information when sending the operating frequency information of the second communication unit. That is, the first resource information further comprises first time information. The first time information corresponds to the operating frequency information of the second communication unit, and represents that the second communication unit occupies the operating frequency information within a time range corresponding to the first time information, so that the first communication unit avoids the corresponding interfered frequency information within the time range.

[0124] Correspondingly, the first communication unit determines the frequency information to be avoided based on the operating frequency information of the second communication unit, comprising:

[0125] The first communication unit determines the frequency information to be avoided within a time range corresponding to the first time information based on the operating frequency information of the second communication unit.

[0126] Exemplarily, the first time information can comprise at least one of a start time, an end time and a time length information. For example, the first time information can comprise an end time, and the time range corresponding to the first time information can be from the time when the information is received to the end time. Alternatively, the first time information can comprise a start time and an end time, and the time range corresponding to the first time information can be from the start time to the end time. Alternatively, the first time information can comprise a time length information, and the end time can be obtained based on the time when the information is received and the time length information, and the time range corresponding to the first time information can be from the time when the information is received to the end time.

[0127] Optionally, the first communication unit can determine the time information corresponding to the frequency information to be avoided based on a preset manner. For example, the second communication unit can not send the corresponding time information when sending the operating frequency information of the second communication unit, and the first communication unit determines the effective time of the frequency information to be avoided based on a preset manner. Two exemplary manners are provided as follows:

[0128] In the example 1, the first communication unit determines the frequency information to be avoided based on the working frequency information of the second communication unit, including: the first communication unit determines the frequency information to be avoided before receiving the i+1th first resource information based on the working frequency information of the second communication unit contained in the i th first resource information, wherein i is an integer greater than or equal to 1.

[0129] That is, in the case that the first communication unit receives a first resource information in which the time information corresponding to the frequency information is uncertain, the first communication unit can consider that the second communication unit always occupies the frequency information before receiving the next first resource information, and determines the frequency information to be avoided before receiving the next first resource information based on the currently known working frequency information of the second communication unit.

[0130] In the example 2, the method for processing the frequency information can further include:

[0131] The first communication unit periodically sends first query information to the second communication unit and receives corresponding first response information.

[0132] In the case that the working frequency information of the second communication unit determined based on the first response information changes, the first communication unit determines that the frequency information to be avoided is invalid.

[0133] That is, the first communication unit determines the frequency information to be avoided based on the received working frequency information of the second communication unit, and periodically and actively queries the frequency occupation of the second communication unit, and when it is found that the frequency occupation of the second communication unit changes, the frequency resource is no longer limited. The frequency occupation can refer to the real-time working frequency information of the second communication unit, or can refer to whether the working frequency information of the second communication unit changes, that is, the query information can be used to obtain the real-time working frequency information of the second communication unit, or the query information can be used to inquire whether the working frequency information of the second communication unit changes.

[0134] Optionally, the first communication unit can query the frequency occupation of the second communication unit through the coordination unit. That is, the first communication unit periodically sends first query information to the second communication unit and receives corresponding first response information, including: the first communication unit periodically sends first query information to the second communication unit through the coordination unit in the terminal device and receives first response information.

[0135] Correspondingly, for the second communication unit, the method for processing the frequency information further includes:

[0136] The second communication unit receives the first query information from the first communication unit and sends corresponding first response information to the first communication unit; wherein the first response information is used by the first communication unit to determine whether the working frequency information of the second communication unit has changed.

[0137] Optionally, the second communication unit receives the first query information from the first communication unit and sends corresponding first response information to the first communication unit, comprising: the second communication unit receives the first query information from the first communication unit and sends corresponding first response information to the first communication unit through the coordination unit in the terminal device.

[0138] Optionally, for the coordination unit, the processing method of the frequency information further comprises:

[0139] The coordination unit sends the first query information to the second communication unit upon receiving the first query information from the first communication unit, and sends the first response information to the first communication unit upon receiving the first response information from the second communication unit.

[0140] Optionally, after the first communication unit determines the frequency information to be avoided, the processing method of the frequency information further comprises:

[0141] The first communication unit determines the working frequency information of the first communication unit based on the frequency information to be avoided.

[0142] For example, for some communication units that can autonomously select idle wireless resources to initiate communication with the opposite end, such as WiFi communication units, Bluetooth communication units, etc., they can determine their own working frequency information based on the frequency information to be avoided.

[0143] Optionally, the first communication unit can report relevant information based on the frequency information in the first resource information to the network, so as to facilitate the network to schedule wireless resources. Specifically, the processing method of the frequency information further comprises:

[0144] The first communication unit sends second resource information related to the working frequency information of the second communication unit to the network device, and the second resource information is used by the network device to determine the working frequency information of the first communication unit.

[0145] For example, for communication units that need to communicate according to network-scheduled time-frequency resources, such as 4G communication units, 5G communication units, and other mobile communication units, they can report second resource information related to the working frequency information of the second communication unit to the network device, so that the network device schedules frequency domain resources based on the second resource information.

[0146] Optionally, the second resource information can include at least one of the following information:

[0147] The operating frequency information of the second communication unit;

[0148] The frequency information to be avoided is determined based on the operating frequency information of the second communication unit;

[0149] The at least one operating frequency information is determined based on the frequency information to be avoided.

[0150] The at least one operating frequency information determined based on the frequency information to be avoided can include other frequency information in the available frequency information of the first communication unit except the frequency information to be avoided, which can be used as the operating frequency information of the first communication unit. Alternatively, the at least one operating frequency information determined based on the frequency information to be avoided can include the operating frequency information expected by the terminal device, for example, the operating frequency information determined by the terminal device after excluding the frequency information to be avoided.

[0151] Optionally, the second resource information can be sent through RRC or physical layer control information.

[0152] Correspondingly, the embodiment of the present application further provides a frequency information processing method applied to a network device. As shown in the method can include: Figure 13

[0153] S410, the network device receives second resource information from the first communication unit in the terminal device; wherein the second resource information is related to the operating frequency information of the second communication unit in the terminal device;

[0154] S420, the network device determines the operating frequency information of the first communication unit based on the second resource information.

[0155] Optionally, the second resource information can further include second time information. The second time information can be used by the network device to determine the time range corresponding to the operating frequency information of the first communication unit.

[0156] Correspondingly, the above step S420, the network device determines the operating frequency information of the first communication unit based on the second resource information, includes:

[0157] The network device determines the operating frequency information of the first communication unit in the time range corresponding to the second time information based on the frequency information in the second resource information.

[0158] That is, when the first communication unit indicates the frequency information to the network, it can also indicate the corresponding second time information, that is, the frequency information is effective in what time range. Exemplarily, the second time information can correspond to the above-mentioned first time information, that is, the second time information indicates the same time range as the first time information. The second time information can include at least one of the start time, end time and duration information of the time range. ​

[0159] Optionally, the network device can also determine the time information corresponding to the working frequency information of the first communication unit based on a preset manner. For example, the first communication unit can not send the corresponding time information when sending the second resource information, and the network device schedules the frequency domain resource and the corresponding time domain resource for the first communication unit based on the preset manner. Two exemplary manners are provided below:

[0160] Example 1: The network device determines the working frequency information of the first communication unit based on the second resource information, including: the network device determines the working frequency information of the first communication unit before receiving the (j+1)th second resource information based on the frequency information in the jth second resource information received, wherein j is an integer greater than or equal to 1.

[0161] That is, in the case where the network device receives a second resource information, the time information corresponding to the frequency information in the second resource information is not determined, the network device can consider that the terminal device is frequency scheduled based on the frequency information in the current second resource information before receiving the next second resource information, for example, in the case where the second resource information includes the working frequency information of the second communication unit, the terminal device is not scheduled on the working frequency information before receiving the next second resource information.

[0162] Example 2: The above frequency information processing method can further include:

[0163] The network device periodically sends first query information to the first communication unit and receives corresponding first response information;

[0164] In the case where the working frequency information of the second communication unit is determined to change based on the first response information, the network device determines not to determine the working frequency information of the first communication unit based on the second resource information.

[0165] Correspondingly, for the first communication unit, the above frequency information processing method can further include:

[0166] The first communication unit receives second query information from the network device and sends corresponding second response information to the network device; wherein the second response information is used by the network device to determine whether the working frequency information of the second communication unit changes.

[0167] That is, the network device periodically actively queries the frequency information from the terminal device, for example, queries the frequency information to be avoided, the working frequency information of the second communication unit, the working frequency information expected by the terminal device, etc., when the frequency information queried by the network device changes, i.e., the working frequency information of the second communication unit changes, the network device can determine not to schedule the first communication unit based on the second resource information.

[0168] Optionally, in the case that the network device periodically sends the first query information to the first communication unit and receives the corresponding first response information, the first communication unit can also periodically send the first query information to the second communication unit and receive the corresponding first response information accordingly. In the case that the first response information determines that the working frequency information of the second communication unit has changed, it is determined that the frequency information to be avoided is invalid, and the second communication unit sends the second response information indicating that the working frequency information of the second communication unit has changed to the network device.

[0169] Optionally, in the above method, the first resource information can be sent in the case that the signal-to-noise ratio and / or interference information of the second communication unit meets a preset condition.

[0170] Optionally, the preset condition includes that the signal-to-noise ratio is greater than a first threshold, and / or the interference information is greater than a second threshold.

[0171] That is, only when the interference actually occurs, the second communication unit informs the first communication unit of the working frequency information, so as to limit the working frequency information of the first communication unit, which can avoid unnecessary limitation and improve the flexibility of communication.

[0172] The following will take the interference between a 5G communication unit and a WiFi communication unit as an example to illustrate some optional embodiments described above. It should be understood that the following is only an application example, and those skilled in the art can also select other optional embodiments to implement the method of the present application.

[0173] As described above, the mutual interference between carriers is usually related to the frequency of the carrier, such as harmonic interference, which is the influence of the multiple frequency of the interfering carrier on the interfered carrier, intermodulation interference, which involves the sum frequency / difference frequency between multiple interfering carriers, and adjacent frequency band leakage interference, which is caused by insufficient frequency band isolation. These interferences not only occur within a communication unit, but also occur between multiple communication units, such as between a 5G communication unit and a WiFi communication unit.

[0174] As shown in Figure 14 , the 5G communication carrier 5 will interfere with the WiFi communication carrier a when transmitting, causing the WiFi communication performance to decrease. Since the 5G communication unit and the WiFi communication unit are in an independent state with each other, this interference is difficult to eliminate or avoid. One solution is to introduce a coordination unit between the 5G communication unit and the WiFi communication unit to communicate information and coordinate resources. For example, as shown in Figure 11 , a coordination unit is introduced between the 5G communication unit and the WiFi communication unit for information exchange between the 5G communication unit and the WiFi communication unit. Of course, the function of the coordination unit can also be included in the 5G communication unit or the WiFi communication unit, which is introduced here from the function.

[0175] WiFi communication units operate in unlicensed frequency bands. Similar to other systems operating in unlicensed frequency bands, their characteristic is that terminals select unoccupied resources for communication. Therefore, the frequency resources used by WiFi communication have a certain degree of randomness (depending on which resources are idle).

[0176] by Figure 15 For example, WiFi occupies frequency resource f3 within the time range t1 to t3. A direct way to avoid interference from the 5G communication unit to the WiFi communication unit is for the WiFi communication unit to inform the 5G communication unit of its first resource information (e.g., currently occupied frequency information, or frequency information and expected occupied time length information) through a coordination unit. Figure 15 In the example, the following approach can be taken:

[0177] Method 1: The WiFi communication unit informs the 5G communication unit of the frequency f3 information through the coordination unit.

[0178] After receiving this frequency information, the 5G communication unit assumes that the WiFi communication unit will communicate using this frequency information for a period of time, but the duration is uncertain.

[0179] • When the duration is uncertain, the measures that a 5G communication unit can take are:

[0180] 1. It can be assumed that the WiFi communication unit will always occupy this frequency until it receives information about a change in frequency.

[0181] 2. Alternatively, the WiFi frequency usage can be periodically and proactively queried through the coordination unit. If a change in WiFi frequency usage is detected, frequency resource restrictions will no longer be imposed.

[0182] Method 2: Inform the 5G communication unit of the frequency f3 and the time range t1 to t3 through the coordination unit.

[0183] After receiving the frequency information, the 5G communication unit assumes that WiFi will communicate via frequency f3 during the subsequent time period t1 to t3.

[0184] After receiving information from either method 1 or method 2, the 5G communication unit needs to take measures to avoid interfering time-frequency resources as much as possible, such as... Figure 16 As shown, the 5G communication unit needs to avoid frequency F1, which is subject to interference from frequency f3. However, there are two areas where enhancement processing is required:

[0185] • First, the 5G communication unit in the terminal, after knowing the operating frequency of the WiFi communication unit, can determine the 5G communication frequency resources that may cause interference through the aforementioned harmonic, intermodulation and leakage frequency relationships. However, the mobile communication unit needs the terminal to transmit and receive according to the time-frequency resources scheduled by the base station, and the terminal does not have the decision-making power to use the time-frequency resources, and there is no way for the terminal to indicate the operating time-frequency resources to the network. Therefore, what needs to be introduced here is the terminal frequency resource indication information (i.e. the second resource information) reported by the terminal to the network, which can be reported through RRC or physical layer control information (the frequency resource indication information can carry time information at the same time in the above-mentioned way 2). The frequency resource indication information can include the following:

[0186] o The frequency resource indication information is used to indicate the frequency information that the terminal expects to avoid, for example Figure 17 the 5G frequency F1 in

[0187] o The frequency resource indication information is used to indicate the operating frequency information of the communication unit that causes interference, for example Figure 17 the WiFi frequency f3 in

[0188] o The frequency resource indication information is used to indicate the operating frequency information that the terminal expects, for example Figure 17 the 5G frequencies F2 to F4 in

[0189] • Second, the time information. When the terminal indicates the frequency resource information to the network, another important information is the time range, that is, the frequency resource indication information needs to work for how long. This information has a clear indication in the above-mentioned way 2, but does not contain this time information content in the above-mentioned way 1. If the base station receives the information of way 1, the measures that can be taken include the following two (similar to the processing mode of the 5G communication unit in way 1):

[0190] 1. The base station does not schedule the terminal on the corresponding frequency in the subsequent time until it receives new frequency indication information;

[0191] 2. The base station periodically actively queries the frequency information from the terminal, and the corresponding 5G communication unit of the terminal queries the WiFi operating frequency information from the WiFi communication unit through the coordination unit.

[0192] In addition to the above, the WiFi communication unit indicates the time-frequency resource information to the 5G communication unit through the coordination unit, so as to avoid the time-frequency resource. Considering that the interference of 5G communication to WiFi communication is affected by various factors, such as 5G transmission power and WiFi signal strength. A further way is that the information indication of the time-frequency resource is only performed to the 5G communication unit when the signal-to-noise ratio of WiFi is lower than a certain strength or the interference is higher than a certain value (the value depends on the WiFi communication unit). The advantage of this way is that the limitation of the time-frequency resource of 5G communication is only performed when the actual interference occurs.

[0193] In addition, the above is described by taking the interference of 5G communication unit to WiFi communication as an example, and the processing mode of the interference of WiFi communication to 5G communication unit is similar. However, since WiFi does not have a resource scheduling center like a 5G base station, when the 5G communication unit informs the WiFi unit of the frequency and time information of its work through the coordination unit, the WiFi communication unit should avoid the corresponding WiFi time-frequency resource with interference relationship when selecting the communication resource.

[0194] The above describes the specific settings and implementation modes of the embodiments of the application from different angles through multiple embodiments. It can be seen that, by using the above at least one embodiment, the frequency coordination is performed between the first communication unit and the second communication unit in the terminal device, so as to avoid the interference between the first communication unit and the second communication unit, and to protect the communication performance.
