[0003] However, there may be conflicts between the radio frequency channels corresponding to different frequency bands in the radio frequency front-end. When the mobile terminal works in different conflicting frequency bands at the same time, there is a problem of poor communication capability of the mobile terminal.
[0004] Currently, due to the increased complexity of mobile terminal RF front-end design, there are a large number of RF channels within the RF front-end.

[0034] With the development of mobile communication networks, in order to obtain a good communication experience under multiple standards and multiple frequency bands, in some scenarios, mobile terminals need to work in different frequency bands at the same time, and the radio frequency front end needs to open the radio frequency channels corresponding to different frequency bands at the same time.
[0035] However, there may be conflicts between the radio frequency channels corresponding to different frequency bands in the radio frequency front-end. When the mobile terminal works in different conflicting frequency bands at the same time, there is a problem of poor communication capability of the mobile terminal.
[0036] Currently, due to the increased complexity of mobile terminal RF front-end design, there are a large number of RF channels within the RF front-end. There is currently a lack of a method to achieve reliable communication across multiple frequency bands and multiple RF channels.
[0037] To address the aforementioned technical problems, this disclosure provides a communication method applied to a communication device including multiple radio frequency channels. The communication device is pre-configured with conflict verification results, which include frequency band combinations and target radio frequency channel combinations corresponding to the frequency band combinations. The frequency band combinations include multiple frequency bands, and the target radio frequency channel combinations include multiple radio frequency channels whose mutual conflict levels meet preset conditions. The method includes: determining that the communication device transmits signals through a target frequency band combination; wherein the target frequency band combination includes at least two frequency bands supported by the communication device; determining a target radio frequency channel combination corresponding to the target frequency band combination based on the conflict verification results; and transmitting signals through the target radio frequency channel combination corresponding to the target frequency band combination. Since the conflict verification results include frequency band combinations and target radio frequency channels corresponding to the frequency band combinations, the target radio frequency channel combination corresponding to the target frequency band combination can be determined from the conflict verification results. Furthermore, since the target radio frequency channel combination corresponding to the target frequency band combination includes multiple radio frequency channels that meet preset conditions, when signals are transmitted through the radio frequency channels in this target radio frequency channel combination, the communication performance of the communication device (e.g., the signal strength of the signal transmitted by the communication device) can meet the requirements of normal communication, thus ensuring communication reliability and effectiveness.
[0038] The communication method provided in this disclosure can be applied to, for example, Figure 1 In the aforementioned communication system, such as Figure 1 As shown, the communication system includes: a communication device 101, a first node 102, and a second node 103.
[0039] The communication device 101 includes multiple radio frequency channels for communicating with the first node 102 and / or the second node 103 based on a target radio frequency channel combination corresponding to a target frequency band combination. The target frequency band combination includes at least two frequency bands supported by the communication device. The target radio frequency channel combination includes multiple radio frequency channels whose mutual conflict level meets preset conditions.
[0040] The first node 102 or the second node 103 is used to communicate with the communication device 101.
[0041] In some embodiments, the first node 102 and the second node 103 may support different frequency bands respectively.
[0042] In some embodiments, the first node 102 or the second node 103 may support multiple frequency bands that can transmit signals simultaneously.
[0043] For example, the communication device 101, the first node 102, or the second node 103 can be a mobile phone, tablet computer, desktop computer, laptop computer, handheld computer, notebook computer, ultra-mobile personal computer (UMPC), netbook, as well as cellular phone, personal digital assistant (PDA), augmented reality (AR) / virtual reality (VR) device. This application embodiment does not impose special limitations on the specific form of the electronic device. It can interact with the user through one or more methods such as a keyboard, touchpad, touch screen, remote control, voice interaction, or handwriting device.
[0044] Alternatively, it can be used for base stations, evolved node base stations (eNBs), next-generation node base stations (gNBs), new radio eNBs, macro base stations, micro base stations, high-frequency base stations or transmission and reception points (TRPs), non-3GPP access networks (such as WiFi), and / or non-3GPP interworking functions (N3IWFs). Figure 1 In this example, the communication device 101 is a mobile phone, and the first node 102 and the second node 103 are base stations.
[0045] It should be noted that, Figure 1 This is just an example framework diagram. Figure 1 The number of devices included and the names of each device are unlimited.
[0046] For example, such as Figure 2 The diagram shown is a schematic diagram of the structure of a radio frequency circuit of a communication device provided in an embodiment of this disclosure, including a radio frequency transceiver 201, a power amplifier, a main receiver module 202, a diversity receiver module 203, a first antenna switch 204, a second antenna switch 205, a first antenna 206, a second antenna 207, a third antenna 208, and a fourth antenna 209.
[0047] The radio frequency transceiver 201 is connected to the power amplifier and the primary receiver module 202 via a primary receive (PRX) path and / or a multiple input multiple output primary receive (MIMO diversity receive, PRX-MIMO) path.
[0048] The power amplifier and main receiver module 202 are connected to the first antenna switch 204 via a main receiver path and / or a multiple-input multiple-output main receiver path. Figure 2 Taking the example of the connection between the power amplifier and the main receiver module 202 and the first antenna switch 204 through the main receiver path and the multiple input multiple output main receiver path.
[0049] The first antenna switch 204 is connected to the first antenna 206 and the second antenna 207 via a master receiver path and / or a multiple-input multiple-output master receiver path.
[0050] In some embodiments, there are multiple master set receive paths or multiple input multiple output master set receive paths. Figure 2 In this example, the RF transceiver 201 is connected to the power amplifier and the main receiver module 202 through main receiver path 1, main receiver path 2, MIMO main receiver path 1, and MIMO main receiver path 2.
[0051] The radio frequency transceiver 201 and the diversity receiver module 203 communicate via a diversity receive (DRX) path and / or a multiple input multiple output diversity receive (DRX-MIMO) path.
[0052] The diversity receiving module 203 and the second antenna switch 205 are connected via a diversity receiving path and / or a multiple-input multiple-output diversity receiving path. Figure 2 Taking the connection between the China-Israel diversity receiving module 203 and the second antenna switch 205 via a diversity receiving path and a multiple-input multiple-output diversity receiving path as an example.
[0053] The second antenna switch 205 is connected to the third antenna 208 and the fourth antenna 209 via a diversity reception path and / or a multiple-input multiple-output diversity reception path.
[0054] The first antenna switch 204 is connected to the second antenna switch 205.
[0055] In some embodiments, there are multiple diversity reception paths or multiple-input multiple-output diversity reception paths. Figure 2In this example, the radio frequency transceiver 201 and the diversity receiving module 203 are connected through diversity receiving path 1, diversity receiving path 2, multiple input multiple output diversity receiving path 1, and multiple input multiple output diversity receiving path 2.
[0056] like Figure 3 The diagram shown is a structural schematic of a communication device provided in an embodiment of this disclosure, including a storage module 301, a control module 302, and a radio frequency module 303.
[0057] The storage module 301 is used to store data and collision verification results of the radio frequency front-end circuit.
[0058] The control module 302 is used to determine the signal transmission requirements of the communication device; or to control the communication device to perform radio frequency channel conflict verification; or to determine whether the combination of radio frequency channels meets the communication requirements; or to generate data corresponding to radio frequency channel conflict verification.
[0059] The radio frequency module 303 includes radio frequency channels (or hardware channels) corresponding to each frequency band.
[0060] It should be noted that, in this embodiment of the disclosure, the entity executing the communication method and the entity executing the radio frequency channel conflict verification process may be the same or different.
[0061] In some embodiments, the pre-configured conflict verification result in the communication device can be obtained by verifying the radio frequency channel conflict between the communication device (or a device with the same radio frequency circuit as the communication device) and the instrument device (by transmitting or receiving signals in a laboratory setting).
[0062] The application scenarios of the embodiments disclosed herein are not limited. The system architecture and business scenarios described in the embodiments of this disclosure are for the purpose of more clearly illustrating the technical solutions of the embodiments of this disclosure, and do not constitute a limitation on the technical solutions provided by the embodiments of this disclosure. As those skilled in the art will know, with the evolution of network architecture and the emergence of new business scenarios, the technical solutions provided by the embodiments of this disclosure are also applicable to similar technical problems.
[0063] The communication method provided in the embodiments of this disclosure will now be described in detail with reference to the accompanying drawings.
[0064] The communication method provided in this disclosure can be applied to... Figure 1 The communication device 101 in the communication system shown. Figure 4 A flowchart of a communication method is shown, such as... Figure 4 As shown, the communication method includes the following S401-S403:
[0065] S401. Determine that the communication device transmits signals through a combination of target frequency bands.
[0066] The communication device includes multiple radio frequency (RF) channels. The communication device is pre-configured with collision verification results, which include frequency band combinations and corresponding target RF channel combinations. Each frequency band combination includes multiple frequency bands. Each target RF channel combination includes multiple RF channels whose mutual collision levels meet preset conditions. Each target frequency band combination includes at least two frequency bands supported by the communication device.
[0067] It should be understood that multiple radio frequency channels include radio frequency channels used to transmit signals in different frequency bands. There can be multiple radio frequency channels used to transmit signals in one frequency band.
[0068] For example, suppose multiple radio frequency channels include: radio frequency channel 1, radio frequency channel 2, radio frequency channel 3, and radio frequency channel 4. Among them, radio frequency channel 1 and radio frequency channel 2 are used to transmit signals of frequency band 1, and radio frequency channel 3 and radio frequency channel 4 are used to transmit signals of frequency band 2.
[0069] It should be understood that if the degree of mutual conflict between multiple radio frequency channels in the target radio frequency channel combination corresponding to a frequency band combination meets the preset conditions, it means that when transmitting signals based on the target radio frequency channel combination, the communication performance of the communication device can meet the needs of normal communication, and the communication quality can meet the expected quality.
[0070] In some embodiments, the communication performance of a communication device can be evaluated by at least one of the following: the signal strength of the transmitted signal, the signal-to-noise ratio of the transmitted signal, the electrical signal (or level signal) corresponding to the transmitted signal, the packet loss rate corresponding to the transmitted data, the frame error rate corresponding to the transmitted signal frame, the packet loss rate corresponding to the transmitted data, and the channel quality indicator (CQI) corresponding to the transmitted signal.
[0071] In some embodiments, the preset condition can be that the degree of mutual conflict in the radio frequency channel combination is lower than the conflict degree threshold.
[0072] In some embodiments, the degree of mutual conflict between radio frequency channels in a radio frequency channel combination can be determined based on at least one of the following: the signal attenuation value corresponding to the simultaneous operation of radio frequency channels in a radio frequency channel combination, the signal coverage range corresponding to the simultaneous operation of radio frequency channels in a radio frequency channel combination, and the strength of the electrical signal received or converted by the antenna corresponding to the simultaneous operation of radio frequency channels in a radio frequency channel combination.
[0073] In some embodiments, the target communication function of the communication device can be activated to determine when the communication device needs to transmit signals through at least two frequency bands. The target communication function is used to trigger the communication device to transmit signals through at least two frequency bands.
[0074] For example, suppose the communication device can activate the function of triggering signal transmission through the frequency bands of the 2G network and the 3G network in response to receiving an instruction to simultaneously transmit signals based on the frequency bands of the 2G network and the 3G network.
[0075] In some embodiments, the frequency bands supported by the communication device may include at least one of the following: some or all frequency bands of 2G networks, some or all frequency bands of 3G networks, some or all frequency bands of 4G networks, some or all frequency bands of 5G networks, some or all frequency bands of wireless media broadcast signals, and some or all frequency bands of satellite communications.
[0076] In some embodiments, the frequency bands supported by the communication device can be one or more of any frequency bands divided according to a standard.
[0077] For example, the frequency bands supported by the communication device can be any frequency band from Table 1. As shown in Table 1:
[0078] Table 1
[0079]
[0080]
[0081] In some embodiments, a channel may also be referred to as a band.
[0082] S402. Determine the target radio frequency channel combination corresponding to the target frequency band combination based on the conflict verification results.
[0083] It should be understood that since the conflict verification results include frequency band combinations and the target RF channels corresponding to the frequency band combinations, the target RF channel combinations corresponding to the target frequency band combinations can be determined from the conflict verification results.
[0084] In some embodiments, the target frequency band combination can be determined by querying the conflict verification results based on the target frequency band combination.
[0085] S403, Transmit signals through the target radio frequency channel combination corresponding to the target frequency band combination.
[0086] It should be understood that since the target frequency band combination includes multiple radio frequency channels that meet the preset conditions, when a signal is transmitted through the radio frequency channels in the target radio frequency channel combination, the signal strength can meet the requirements of normal communication, thus ensuring the reliability and effectiveness of communication.
[0087] In some embodiments, the transmitted signal includes a transmit and / or receive signal.
[0088] In some embodiments, the conflict verification result includes a whitelist and / or a blacklist. The whitelist includes frequency band combinations and target RF channel combinations corresponding to the frequency band combinations, while the blacklist includes frequency band combinations and unavailable channel combinations corresponding to the frequency band combinations. Unavailable channel combinations include multiple RF channels whose mutual conflict does not meet preset conditions.
[0089] It should be understood that the target radio frequency channel combination of the frequency band combination is used to transmit the signals of that frequency band combination, which can ensure the reliability and effectiveness of communication.
[0090] Furthermore, the target RF channel combination and the unavailable channel combination of the frequency band combination are used to determine whether a RF channel combination is available when there is an indication that signal transmission is based on a RF channel combination. When the RF channel combination is the target RF channel combination, the RF channel combination is available; when the RF channel combination is an unavailable RF channel combination, the RF channel combination is unavailable.
[0091] In some embodiments, the above-described S403, transmitting signals through the target radio frequency channel combination corresponding to the target frequency band combination, is achieved in the following way: when the target radio frequency channel combination corresponding to the target frequency band combination exists in the whitelist, the signal is transmitted through the target radio frequency channel combination corresponding to the target frequency band combination.
[0092] It should be understood that if a target frequency band combination exists in the whitelist, it means that the target frequency band combination contains a combination of radio frequency channels that meet the preset conditions, and that the target radio frequency channel combination corresponding to the target frequency band combination can meet the requirements of normal communication. In this case, signals can be transmitted through the target radio frequency channel combination corresponding to the target frequency band combination. This ensures the reliability and effectiveness of communication.
[0093] In some embodiments, the communication method further includes: when there is no target radio frequency channel combination corresponding to the target frequency band combination in the whitelist, performing radio frequency channel conflict verification on multiple radio frequency channel combinations corresponding to the target frequency band combination, and determining the radio frequency channel combination whose mutual conflict level meets the preset conditions as the target radio frequency channel combination.
[0094] It should be understood that if the target frequency band combination does not exist in the whitelist, it indicates that the corresponding RF channel combination may not have been verified. In this case, RF channel conflict verification can be performed on multiple RF channel combinations corresponding to the target frequency band combination, and the RF channel combination whose mutual conflict level meets preset conditions can be determined as the target RF channel combination. In this way, even if the RF channel corresponding to the target frequency band combination has not been verified, the RF channel combination that meets normal communication requirements can be determined in real time. Furthermore, the communication device can transmit signals based on the target RF channel corresponding to the target frequency band combination obtained through real-time verification, ensuring the reliability and effectiveness of communication.
[0095] In some embodiments, after determining the radio frequency channel combination that meets the preset conditions for mutual conflict as the target radio frequency channel combination, the communication method further includes: adding the radio frequency channel combination that meets the preset conditions for mutual conflict to a whitelist.
[0096] It should be understood that adding radio frequency channel combinations that meet preset conditions for mutual conflict to the whitelist allows the communication device to directly determine the target radio frequency channel combination corresponding to the target frequency band combination based on the whitelist when it needs to transmit signals based on the target frequency band combination again, without having to perform radio frequency channel conflict verification again.
[0097] In some embodiments, when there is no target radio frequency channel combination corresponding to the target frequency band combination in the whitelist, radio frequency channel conflict verification is performed on multiple radio frequency channel combinations corresponding to the target frequency band combination, and the radio frequency channel combination whose mutual conflict level meets the preset conditions is determined as the target radio frequency channel combination. This includes: when there is no target radio frequency channel combination corresponding to the target frequency band combination in the whitelist and no target frequency band combination in the blacklist, radio frequency channel conflict verification is performed on multiple radio frequency channel combinations corresponding to the target frequency band combination, and the radio frequency channel combination whose mutual conflict level meets the preset conditions is determined as the target radio frequency channel combination.
[0098] It should be understood that if the target frequency band combination does not exist in the whitelist but exists in the blacklist, it indicates that the target frequency band combination has undergone radio frequency conflict verification, and there is no radio frequency channel combination that meets the preset conditions. In this case, radio frequency channel conflict verification is unnecessary. However, if the target frequency band combination does not exist in both the whitelist and the blacklist, it indicates that the conflict verification results do not store the verification results for the target frequency band combination, and verification of multiple radio frequency channel combinations corresponding to the target frequency band combination is required. In this case, radio frequency channel conflict verification is performed on multiple radio frequency channel combinations corresponding to the target frequency band combination, and the radio frequency channel combination whose mutual conflict level meets the preset conditions is determined as the target radio frequency channel combination. In this way, the whitelist and blacklist can more accurately determine whether the radio frequency channel corresponding to the target frequency band combination has been verified, and can determine the radio frequency channel combination that meets the normal communication requirements in real time even if the radio frequency channel corresponding to the target frequency band combination has not been verified. Consequently, the communication device can transmit signals based on the target radio frequency channel corresponding to the target frequency band combination obtained through real-time verification, ensuring the reliability and effectiveness of communication.
[0099] In some embodiments, the communication method further includes: when there is no target radio frequency channel combination corresponding to the target frequency band combination in the whitelist, performing radio frequency channel conflict verification on multiple radio frequency channel combinations corresponding to the target frequency band combination, and adding the target frequency band combination to the blacklist when there is no radio frequency channel combination whose mutual conflict level meets the preset conditions.
[0100] It should be understood that if no radio frequency channel combination meets the preset conditions for mutual conflict, it indicates that the target frequency band combination does not have a radio frequency channel combination that meets the communication requirements. In this case, the target frequency band combination is added to the blacklist. Thus, when it is necessary to transmit signals based on the target frequency band combination again, the communication device can determine from the blacklist that the target frequency band combination does not have a radio frequency channel combination that meets the communication requirements, and cannot transmit signals based on the target frequency band combination, without having to perform radio frequency channel conflict verification on the target frequency band combination.
[0101] In some embodiments, the communication method further includes: generating target prompt information if all radio frequency channel combinations corresponding to the target frequency band combination exist in the blacklist. The target prompt information is used to indicate that signals cannot be transmitted simultaneously through the target frequency band combination.
[0102] It should be understood that after generating this target prompt information, the communication device can, in scenarios requiring signal transmission based on a target frequency band, inform the user that it cannot transmit signals based on that target frequency band, or indicate that the communication device does not support signal transmission based on that target frequency band if interaction is required. This allows for prompting the user or the device to be interacted with, improving the user experience, or providing feedback on the actual situation of the communication device to the device to be interacted with, enabling the communication device and the device to communicate using other reliable methods.
[0103] In some embodiments, the communication device may display the target prompt information based on a display interface.
[0104] In some embodiments, the communication device may send the target prompt information to the device to be interacted with.
[0105] For example, suppose the devices to be interacted with include device 1 and device 2, where device 1 supports frequency band 1 and device 2 supports frequency band 2. The communication device can send target prompt information to device 1 and device 2 respectively based on frequency band 1 and frequency band 2.
[0106] In some embodiments, there are multiple target RF channel combinations, and different target RF channel combinations include different numbers of RF channels. In S403 above, the signal is transmitted through the target RF channel combination corresponding to the target frequency band combination, which is achieved by transmitting the signal based on the target RF channel combination with the largest number of RF channels among the multiple target RF channel combinations.
[0107] It should be understood that the more radio frequency channels in a target radio frequency channel combination, the higher the communication quality when transmitting signals based on those channels. Therefore, signals can be transmitted based on the target radio frequency channel combination with the most radio frequency channels among various combinations. This can improve communication quality and user experience.
[0108] In some embodiments, conflict verification results can be obtained through radio frequency channel conflict verification. For example... Figure 5 As shown, RF channel conflict verification is performed in the following way:
[0109] S501. Obtain the frequency band combination of the communication device, and the various radio frequency channel combinations corresponding to the frequency band combination.
[0110] The frequency band combination includes multiple frequency bands that need to transmit signals simultaneously.
[0111] In some embodiments, the frequency band combination can be any combination of multiple frequency bands supported by the communication device.
[0112] In some embodiments, the frequency band combination is the target frequency band combination described above.
[0113] S502. For multiple RF channel combinations corresponding to the frequency band combination, perform RF channel conflict verification, and determine the RF channel combination whose mutual conflict level meets the preset conditions as the target RF channel combination corresponding to the frequency band combination.
[0114] It should be understood that by verifying the conflict between multiple radio frequency (RF) channel combinations corresponding to a frequency band combination, the degree of conflict between RF channels in each RF channel combination can be obtained. If the degree of conflict between RF channel combinations meets a preset condition, it indicates that the signal transmitted based on that RF channel combination can meet the requirements of normal communication. At this point, the RF channel combination whose degree of conflict meets the preset condition is determined as the target RF channel combination corresponding to the frequency band combination. In this way, the target RF channel combination corresponding to the frequency band combination can be obtained accurately and reliably.
[0115] In some embodiments, the communication device may determine the combination of radio frequency channels with a mutual conflict level below a conflict level threshold as the target radio frequency channel combination corresponding to the frequency band combination.
[0116] In some embodiments, the degree of mutual conflict between radio frequency channel combinations can be determined by at least one of the following: the signal strength attenuation value corresponding to the transmitted signal, the attenuation value of the electrical signal (or level signal) corresponding to the transmitted signal, the signal-to-noise ratio of the transmitted signal, the packet loss rate corresponding to the transmitted data, the frame error rate corresponding to the transmitted signal frame, the packet loss rate corresponding to the transmitted data, and the channel quality indicator (CQI) corresponding to the transmitted signal.
[0117] In some embodiments, any one of the multiple RF channel combinations corresponding to a frequency band combination may be referred to as the first RF channel combination. Figure 5 The illustrated embodiments, such as Figure 6 As shown, this describes the process of performing radio frequency channel conflict verification on the first radio frequency channel combination, and determining the radio frequency channel combination whose mutual conflict level meets the preset conditions as the target radio frequency channel combination corresponding to the frequency band combination:
[0118] S601. Obtain the signal strength attenuation value corresponding to each radio frequency channel in the first radio frequency channel combination.
[0119] It should be understood that the signal strength attenuation value corresponding to one radio channel in the first radio channel combination is the difference between the signal strength corresponding to that radio channel when transmitting a signal alone and the signal strength corresponding to that radio channel when transmitting signals simultaneously with the other radio channels in the first radio channel combination.
[0120] In some embodiments, when the communication device receives a signal, it can receive the signal individually through the radio frequency channel, and simultaneously receive the signal through other radio frequency channels in the combination of the radio frequency channel and the first radio frequency channel, and determine the signal strength attenuation value corresponding to the radio frequency channel.
[0121] In some embodiments, when the communication device transmits a signal, the signal can be transmitted individually through a radio frequency channel, and signals can be transmitted simultaneously through other radio frequency channels in the combination of the radio frequency channel and the first radio frequency channel; and the device interacting with the communication device can determine the signal strength attenuation value corresponding to the radio frequency channel; the device interacting with the communication device can send the signal strength attenuation value corresponding to the radio frequency channel to the communication device.
[0122] In some embodiments, the signal strength attenuation value corresponding to the radio frequency channel can be determined by acquiring the electrical signal (or level signal) corresponding to the radio frequency channel when transmitting the signal.
[0123] In some embodiments, a signal can be transmitted individually through a radio frequency channel, and signals can be transmitted simultaneously through other radio frequency channels in the combination of the radio frequency channel and the first radio frequency channel. The difference in electrical signals corresponding to the radio frequency channel when transmitting signals in the two cases can be determined; and the signal strength attenuation value corresponding to the radio frequency channel can be determined based on the difference in electrical signals.
[0124] S602. If the signal strength attenuation value corresponding to each RF channel is less than the attenuation threshold, the first RF channel is determined as the target RF channel combination corresponding to the frequency band combination.
[0125] It should be understood that if the signal strength attenuation value corresponding to each RF channel is less than the attenuation threshold, it indicates that when each RF channel in the RF channel combination works simultaneously, the signal transmitted by each RF channel can meet the requirements of normal communication. In this case, the first RF channel is determined as the target RF channel combination of the frequency band combination. In this way, the target RF channel combination corresponding to the frequency band combination can be reliably and accurately determined from the various RF channel combinations corresponding to the frequency band combination.
[0126] In some embodiments, combined with Figure 6 The illustrated embodiments, such as Figure 7 As shown, when receiving signals through a combination of multiple radio frequency channels, the above-mentioned S601 obtains the signal strength attenuation value corresponding to each radio frequency channel in the first radio frequency channel combination in the following manner:
[0127] S701. Obtain the first received signal strength and the second received signal strength of the first radio frequency channel combination.
[0128] Wherein, the first received signal strength is the received signal strength of each radio frequency channel when it operates individually in the first radio frequency channel combination. The second signal strength is the received signal strength of each radio frequency channel when it operates simultaneously in the first radio frequency channel combination.
[0129] S702. Based on the first received signal strength and the second received signal strength, determine the signal strength attenuation value corresponding to each radio frequency channel in the first radio frequency channel combination.
[0130] In some embodiments, based on the first received signal strength and the second received signal strength, the signal strength attenuation value corresponding to each radio frequency channel in the first radio frequency channel combination is determined by the following method: the signal strength corresponding to the first radio frequency channel in the first received signal strength is subtracted from the signal strength corresponding to the first radio frequency channel in the second received signal strength to obtain the signal strength attenuation value corresponding to the first radio frequency channel. The first radio frequency channel is one of the radio frequency channels in the first radio frequency channel combination.
[0131] In some embodiments, the conflict verification result includes a whitelist. RF channel conflict verification also includes adding the target RF channel combination of the frequency band combination to the whitelist.
[0132] In some embodiments, the radio frequency channel conflict verification further includes: performing radio frequency channel conflict verification on multiple radio frequency channel combinations corresponding to the frequency band combination, and determining the radio frequency channel combinations whose mutual conflict degree does not meet the preset conditions as unusable channel combinations of the frequency band combination.
[0133] In some embodiments, the conflict verification result includes a blacklist, and the radio frequency channel conflict verification further includes adding unusable channel combinations of frequency band combinations to the blacklist.
[0134] The disclosed embodiments can divide the communication device into functional modules according to the above method embodiments. For example, each function can be divided into a separate functional module, or two or more functions can be integrated into one functional module. The integrated module can be implemented in hardware or software.

[0151] In some embodiments, for multiple RF channel combinations corresponding to a frequency band combination, RF channel conflict verification is performed.
