[0033] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0034] It is understood that the terms "first," "second," etc., used in this application may be used to describe various elements herein, but these elements are not limited by these terms. These terms are only used to distinguish one element from another. For example, without departing from the scope of this application, a first radio frequency circuit may be referred to as a second radio frequency circuit, and similarly, a second radio frequency circuit may be referred to as a first radio frequency circuit. Both the first radio frequency circuit and the second radio frequency circuit are radio frequency circuits, but they are not the same radio frequency circuit.

[0035] The communication control method and apparatus provided in this application can be applied to radio frequency systems and electronic devices. The electronic devices can be, but are not limited to, various personal computers, laptops, smartphones, tablets, IoT devices, and portable wearable devices. IoT devices can include smart speakers, smart TVs, smart air conditioners, smart cars, and smart in-vehicle devices. Portable wearable devices can include smartwatches, smart bracelets, and head-mounted devices.

[0036] In one of the embodiments, such as Figure 1 As shown, the radio frequency system may include a first radio frequency circuit 10 and a second radio frequency circuit 20, wherein either the first radio frequency circuit 10 or the second radio frequency circuit 20 can support a first operating frequency band, and the other can support a second operating frequency band. The radio frequency system is used for communication via at least one of the first and second operating frequency bands, which are different from each other.

[0037] When one of the first RF circuits 10 and the second RF circuit 20 communicates, the RF system performs single-band communication; when both the first RF circuit 10 and the second RF circuit 20 communicate, the RF system performs dual-band aggregation communication using the first and second operating frequency bands. For example,... Figure 1As shown, the radio frequency system may also include a combiner, allowing the first radio frequency circuit 10 and the second radio frequency circuit 20 to perform dual-band aggregated communication via the same antenna through the combiner 30. It is understood that in dual-band aggregated communication, the first radio frequency circuit and the second radio frequency circuit can also transmit communication data through their respective connected antennas. It is also understood that the radio frequency system may include other combining devices, enabling the first radio frequency circuit 10 and the second radio frequency circuit 20 to perform dual-band aggregated communication through these other devices.

[0038] For example, the first radio frequency circuit 10 and the second radio frequency circuit 20 can respectively support the transmission processing of radio frequency signals in a preset frequency band to be transmitted. The preset frequency band is either a first operating frequency band or a second operating frequency band. The radio frequency signals are transmitted through the same or different antennas, enabling the radio frequency system to support uplink communication with network devices. For example, the first radio frequency circuit 10 and the second radio frequency circuit 20 can respectively support the reception processing of radio frequency signals in the preset frequency band received by the antenna, enabling the radio frequency system to support downlink communication with network devices. Network devices can be, for example, connection sites such as base stations or routers; network devices can also be other electronic devices.

[0039] In one of the embodiments, such as Figure 2 As shown, the communication control method includes steps 202 and 204.

[0040] Step 202: When the radio frequency system is conducting single-band communication through the first target frequency band, obtain the current communication quality of the radio frequency system.

[0041] The first target frequency band refers to either the first or second operating frequency band currently used for single-band communication. When the RF system is performing single-band communication, the communication status of the RF system operating in the first target frequency band is monitored to obtain the current communication quality. By monitoring the communication quality of the current single-band communication and combining it with the analysis and judgment of the operating frequency band in subsequent steps, a decision-making basis is provided for the RF system's operating mode switching, frequency band switching, or power configuration, thereby improving the transmission reliability and performance of the RF system in complex communication environments and enhancing the communication quality of the RF system.

[0042] Step 204: If the communication quality does not meet the preset communication quality, control the radio frequency system to perform target communication according to the frequency range of the first target frequency band.

[0043] The preset requirements can be set according to the actual needs of the radio frequency system. For example, if the radio frequency system is currently in a call scenario, the call quality threshold can be set based on the needs of the call scenario. It is understandable that when the radio frequency system is conducting single-band communication, due to the single frequency band, it may be limited by the channel, spectrum resource capacity and external environmental interference of that single frequency band, which may result in limited coverage and / or insufficient communication resources, causing the communication quality of the radio frequency system to fail to meet the preset communication quality.

[0044] In cases where the communication quality of a single-band radio frequency (RF) system fails to meet the preset communication quality, the RF system can be controlled to perform target communication based on the frequency range of the current operating frequency band to improve the communication quality of the RF system. Target communication includes either switching the RF system to single-band communication via a second target frequency band, or performing dual-band aggregation communication via a first and a second operating frequency band.

[0045] In this context, the radio frequency (RF) system switches to single-band communication via a second target frequency band. This can be understood as the RF system still operating in a single-band communication state, but switching from communication via the first target frequency band to communication via the second target frequency band. The second target frequency band is a frequency band different from the first target frequency band within the first and second operating frequency bands. For example, if the communication quality of the RF system via the first target frequency band does not meet the preset communication quality, but the communication quality via the second target frequency band does, then switching to single-band communication via the second target frequency band improves the overall electronic communication quality.

[0046] Dual-band aggregation communication can be understood as aggregating the communication resources of the first and second operating frequency bands, that is, aggregating the spectrum bandwidth of different operating frequency bands with their corresponding transmission channels to improve communication quality.

[0047] It is understood that in some possible embodiments, the radio frequency system can support switching between single-band communication and different frequency bands, as well as switching between single-band and dual-band communication. In these embodiments, the experience of switching between single-band communication and different frequency bands, or between single-band and dual-band communication, is mainly based on the simple on / off state of different operating frequency bands. On the one hand, the experience of simply turning on and off is relatively rigid and cannot be dynamically switched based on user experience, communication needs, and other indicators. On the other hand, in single-band communication, it is also limited by the channel, spectrum resource capacity, and external environmental interference of a single frequency band, which may result in communication quality not meeting the preset communication quality.

[0048] The communication control method provided in this embodiment is applied to a radio frequency (RF) system. The RF system communicates through at least one of a first operating frequency band and a second operating frequency band. When the RF system is performing single-band communication through the first target frequency band, the current communication quality of the RF system is obtained. When the communication quality does not meet the preset communication quality, the RF system is controlled to perform target communication according to the frequency range of the first target frequency band. This allows the RF system to switch to single-band communication through the second target frequency band, or to perform dual-band aggregated communication through the first and second operating frequency bands. This improves the communication quality of the RF system, dynamically matches communication needs, and enhances the user experience.

[0049] In one embodiment, communication quality includes at least one of the following: the coverage of the network that can be accessed when the radio frequency system performs single-band communication through the first target frequency band, and the communication resources that can be used for communication transmission.

[0050] Coverage capability can be understood as the ability of an RF system to detect network device signals and successfully connect to the network. It is the fundamental capability that determines whether an RF system can communicate with network devices. The stronger the coverage capability, the better the communication quality. Communication resources can be understood as the resources that network devices, such as routers or base stations, can allocate to the RF system for actual data / voice transmission after communication is established. These resources include frequency band resources (different frequency bands have different transmission rates and anti-interference capabilities) and time / frequency resource blocks (which can be simply understood as transmission channels; the more and wider the channels, the faster the data transmission). When the network device has a lower load and more resources can be allocated to the RF system, the better the communication quality of the RF system.

[0051] It is understandable that when a radio frequency (RF) system communicates with signals in different frequency bands, the coverage and communication resources of the RF system will differ due to the differences in channel capacity, spectrum resource capacity, transmission rate, and anti-interference capability of different frequency bands. For example, in this embodiment, the RF system has different coverage capabilities and communication resources when operating in the first operating frequency band and when operating in the second operating frequency band.

[0052] For example, the coverage capability of the radio frequency system for communication in the first operating frequency band is greater than that for communication in the second operating frequency band; the communication resources of the radio frequency system for communication in the first operating frequency band are less than those of the radio frequency system for communication in the second operating frequency band.

[0053] Therefore, based on the frequency range of the current first target frequency band, it can be determined whether the coverage capability of the RF system operating in the first target frequency band is stronger than that operating in the second target frequency band, and whether the communication resources of the RF system operating in the first target frequency band are more than those operating in the second target frequency band. Based on the current communication quality monitoring, the strength of the coverage capability of the first target frequency band and the size of the communication resources, the operating state of the RF system can be effectively switched. This enables dynamic matching of communication needs, improves the communication quality of the RF system, and enhances the user experience.

[0054] In one embodiment, the first and second operating frequency bands use the same communication standard. For example, the first and second operating frequency bands are respectively short-range wireless standard bands, which may include either Wi-Fi or Bluetooth (BT). It is understood that the embodiments of this application are not limited to the aforementioned Wi-Fi and BT standards, and these will not be described in detail here.

[0055] For example, the first operating frequency band and the second operating frequency band are respectively Wi-Fi standard frequency bands. The first operating frequency band may include the 2.4 GHz Wi-Fi band, and the second operating frequency band may include the 5 GHz Wi-Fi band; or, the first operating frequency band may include the 5 GHz Wi-Fi band, and the second operating frequency band may include the 2.4 GHz Wi-Fi band. The frequency range of 2.4 GHz Wi-Fi is 2400 MHz-2483.5 MHz, and the frequency range of 5 GHz Wi-Fi is 5150 MHz-5850 MHz.

[0056] The radio wave propagation characteristics of the 2.4GHz and 5GHz Wi-Fi bands differ: the 2.4GHz band has strong diffraction capability and low penetration loss, making it suitable for long-distance coverage. The coverage capability of a radio frequency system operating in the 2.4GHz band is greater than that of a radio frequency system performing 5G Wi-Fi communication. The 5GHz band has abundant bandwidth resources and less channel interference, making it suitable for short-distance high-speed transmission. The communication resources of a radio frequency system operating in the 5GHz band are greater than those of a radio frequency system performing 2.4GHz Wi-Fi communication.

[0057] Switching the radio frequency system to 2.4G Wi-Fi communication can improve the coverage of the radio frequency system during communication; switching the radio frequency system to 5G Wi-Fi communication can improve the communication resources of the radio frequency system during communication; switching the radio frequency system to dual-band aggregation communication of 2.4G Wi-Fi and 5G Wi-Fi can simultaneously improve the coverage and communication resources of the radio frequency system during communication.

[0058] For example, when the radio frequency system performs dual-band aggregated uplink communication via 2.4G Wi-Fi and 5G Wi-Fi, the frequencies between 2.4G and 5G can be combined using a combiner and then transmitted through the same antenna. When the radio frequency system performs dual-band aggregated downlink communication via 2.4G Wi-Fi and 5G Wi-Fi, the frequencies between 2.4G and 5G can be separated using a combiner and fed into the first radio frequency circuit and the second radio frequency circuit. During the 2.4G and 5G dual-band aggregated communication process, communication quality requirements can be matched.

[0059] The following examples, using some optional embodiments, illustrate step by step how this application, when performing single-band communication in a radio frequency system, solves the problem of limited communication resources and / or limited coverage in a single band based on the determination of the frequency range of the first target frequency band, thereby dynamically matching communication needs, improving the communication quality of the radio frequency system, and enhancing the user experience:

[0060] In one embodiment, when the communication quality does not meet the preset communication quality, the radio frequency system is controlled to perform target communication according to the frequency range of the first target frequency band. This includes: when the coverage capability of the radio frequency system performing single-channel single-band communication through the first target frequency band is less than the preset coverage capability, and the first target frequency band is the first working frequency band, the radio frequency system is controlled to perform dual-band aggregation communication through the first working frequency band and the second working frequency band respectively, and the same target communication data is transmitted through the first working frequency band and the second working frequency band respectively.

[0061] In this case, the coverage capability of the radio frequency system (RF system) during single-channel single-band communication in the first target frequency band is less than the preset coverage capability. Therefore, single-channel single-band communication in the first target frequency band cannot achieve good coverage, resulting in limited coverage, such as limited uplink and downlink coverage. Limited coverage may cause the RF system and electronic devices to be unable to communicate normally in certain areas, such as with weak or no signal, affecting voice calls, data transmission, and other services. For example, parameters such as the transmit power (uplink), signal strength, and bit error rate (BER) of the RF system during single-band communication in the first target frequency band can be obtained and compared with preset parameter thresholds. Based on a single comparison result or multiple results, it can be determined whether the preset requirements are met. For example, if the transmit power is greater than the power threshold, or the signal strength is lower than the strength threshold, it is determined that there is a coverage limitation problem.

[0062] When the radio frequency system communicates through a first operating frequency band and a second operating frequency band, the signals transmitted by the radio frequency system in the first and second frequency bands respectively carry or transmit the target communication data, thereby realizing the transmission of the target communication data during the communication process. The fact that the radio frequency system transmits the same target communication data through the first and second operating frequency bands can be understood as the first and second frequency band signals carrying or transmitting the same target communication data.

[0063] On the one hand, by combining the first and second target frequency bands, the spectral bandwidth of different operating frequency bands and their corresponding transmission channels can be aggregated, thereby achieving the aggregation of overall communication resources of the radio frequency system and improving communication quality. On the other hand, by transmitting the same target communication data during dual-band communication, the coverage capability of the target communication data transmission can be enhanced to match the current coverage capability requirements and improve communication quality.

[0064] For example, when a radio frequency (RF) system switches from uplink communication via a single 2.4 GHz Wi-Fi band to uplink communication via a dual-band aggregation of 2.4 GHz and 5 GHz Wi-Fi, and transmits the same target communication data through both bands, it's equivalent to doubling the transmission power of the RF system transmitting the target communication data. This effectively increases uplink transmission power, enhances signal strength, and thus improves uplink coverage. Similarly, when a RF system switches from downlink communication via a single 2.4 GHz Wi-Fi band to downlink communication via a dual-band aggregation of 2.4 GHz and 5 GHz Wi-Fi, and receives the same target communication data through both bands, it's equivalent to merging the two target communication data streams. This effectively enhances the energy intensity of the received signal, effectively improving downlink reception quality and thus increasing downlink coverage.

[0065] This embodiment improves the coverage and communication quality of the radio frequency system by controlling it to perform dual-band aggregation communication through the first and second working frequency bands respectively, and transmitting the same target communication data through the first and second working frequency bands respectively, when the coverage capability of the radio frequency system is less than the preset coverage capability and the first target frequency band is the first working frequency band.

[0066] In one embodiment, when the communication quality does not meet the preset communication quality, the radio frequency system is controlled to perform target communication according to the frequency range of the first target frequency band. The method further includes: when the coverage capability of the radio frequency system is less than the preset coverage capability when performing single-band communication with multiple spatial multiplexing through the first target frequency band, and the first target frequency band is the first working frequency band, the radio frequency system is controlled to perform single-channel single-band communication through the first target frequency band.

[0067] For example, in this embodiment, when the radio frequency system performs single-band communication, it can support multiple spatial multiplexing and MIMO (Multiple Input Multiple Output) mode. This splits a single target communication data stream into multiple independent spatial streams, enabling parallel transmission of multiple streams within a single frequency band. This overcomes the rate bottleneck of single-stream transmission, significantly improving the communication bandwidth and throughput of a single frequency band and increasing the communication resources of the radio frequency system. For instance, the radio frequency system may include multiple first radio frequency circuits and multiple second radio frequency circuits. By activating multiple first radio frequency circuits or multiple second radio frequency circuits, the coordinated operation of multiple radio frequency circuits and multiple antennas enables parallel transmission of multiple spatial streams within the same frequency band.

[0068] For example, in this embodiment, when the radio frequency system performs single-band communication, it can support single-channel single-band communication and SISO (Single Input Single Output) mode, which transmits a single data stream through only one radio frequency circuit and one antenna. Taking uplink communication as an example, in this mode, the radio frequency system can concentrate the transmit power resources originally allocated to multiple spatial streams on a single transmission link, improve the effective omnidirectional radiation power of the single signal, thereby enhancing the signal coverage capability of the single band and the transmission reliability in weak signal scenarios, while also helping to reduce the power consumption of the radio frequency system.

[0069] It is understandable that when the RF system is in MIMO mode, if the current first target frequency band is already a first operating frequency band with strong coverage, but the coverage capability of the RF system communication still cannot meet the preset coverage capability requirement, the MIMO mode can be switched to SISO mode to improve the signal coverage capability of a single frequency band and the transmission reliability in weak signal scenarios. This can reduce the power consumption that may occur when using dual-band aggregation while matching communication quality. It is also understandable that when the coverage capability of the RF system performing single-channel single-band communication through the first target frequency band is still less than the preset coverage capability requirement, the steps in the above embodiments are repeated to ultimately control the RF system to perform dual-band aggregation communication.

[0070] This embodiment improves the coverage capability of the radio frequency system by controlling it to perform single-channel single-band communication through the first target frequency band when the coverage capability of the radio frequency system is less than the preset coverage capability and the first target frequency band is the first working frequency band. This can improve the coverage capability of the radio frequency system and reduce the power consumption that may occur when using dual-band aggregation while matching the communication quality.

[0071] In one embodiment, when the communication quality does not meet the preset communication quality, the radio frequency system is controlled to perform target communication according to the frequency range of the first target frequency band. The method further includes: when the coverage capability of the radio frequency system performing single-band communication through the first target frequency band is less than the preset coverage capability, and the first target frequency band is the second working frequency band, the radio frequency system is controlled to switch to performing single-band communication through the first working frequency band; and the first working frequency band is updated to the first target frequency band currently performing single-band communication.

[0072] Referring to the above embodiments, the coverage capability of the radio frequency system operating in the first operating frequency band is greater than that of the radio frequency system operating in the second operating frequency band. Therefore, when the coverage capability of the radio frequency system performing single-band communication through the first target frequency band is less than the preset coverage capability, and the first target frequency band is the second operating frequency band, the radio frequency system can be controlled to switch to single-band communication through the first operating frequency band, updating the first operating frequency band to the first target frequency band currently used for single-band communication. Then, the determination of whether the coverage capability meets the preset coverage capability requirement is repeated as described in the above embodiments. If it is determined that the coverage capability of the radio frequency system performing single-band communication through the first operating frequency band meets the preset coverage capability requirement, then the radio frequency system continues to perform single-band communication through the first operating frequency band. This reduces the energy consumption of dual-band communication and lowers communication costs while ensuring the coverage capability requirement is met. If the coverage capability of the radio frequency system is still less than the preset coverage capability requirement, the radio frequency system is controlled to perform dual-band communication to improve communication quality.

[0073] In one embodiment, when the communication quality does not meet the preset communication quality, the radio frequency system is controlled to perform target communication according to the frequency range of the first target frequency band. This includes: when the communication resources of the radio frequency system are less than the preset communication resources when performing single-band communication through the first target frequency band, and the first target frequency band is the second working frequency band, the radio frequency system is controlled to perform dual-band aggregation communication through the first working frequency band and the second working frequency band respectively, and to transmit different target communication data through the first working frequency band and the second working frequency band respectively.

[0074] In this case, the communication resources of the radio frequency system (RF system) for single-band communication through the first target frequency band are less than the preset communication resources. Therefore, single-channel single-band communication within the first target frequency band cannot be performed effectively, resulting in resource constraints, such as limited uplink resources (which can be understood as uplink congestion) and limited downlink resources (which can be understood as downlink congestion). These resource constraints may cause the RF system and electronic devices to be unable to communicate normally in certain areas, leading to problems such as degraded communication quality and reduced data rates. For example, parameters such as the transmit power (if uplink), signal strength, and bit error rate (BER) of the RF system during single-band communication in the first target frequency band can be obtained and compared with preset parameter thresholds. Based on a single comparison result or multiple results, it can be determined whether the preset requirements are met. For instance, if the transmit power is less than the power threshold, or the signal strength is higher than the strength threshold, a resource constraint problem is identified.

[0075] When the radio frequency system communicates through a first operating frequency band and a second operating frequency band, the signals transmitted by the radio frequency system in the first and second frequency bands respectively carry or transmit target communication data to achieve the transmission of target communication data during the communication process. The radio frequency system transmitting different target communication data through the first and second operating frequency bands can be understood as the first and second frequency band signals carrying or transmitting different target communication data.

[0076] On the one hand, by aggregating the first and second target frequency bands, the spectrum bandwidth of different operating frequency bands and their corresponding transmission channels can be aggregated, thereby aggregating the overall communication resources of the radio frequency system and improving communication quality. On the other hand, by transmitting different target communication data through dual-band communication, the spectrum resources of the first and second operating frequency bands are independent of each other, and the bandwidth of the two frequency bands can be used simultaneously to carry different communication data, further matching the current communication resource requirements and improving communication quality.

[0077] For example, when a radio frequency (RF) system switches from uplink communication via a single 5G Wi-Fi band to uplink communication via a dual-band aggregation of 2.4G Wi-Fi and 5G Wi-Fi, and transmits different target communication data through the two bands respectively, it is equivalent to doubling the RF system throughput. This effectively increases uplink communication resources, improves signal strength, and thus enhances uplink coverage. Similarly, when a RF system switches from downlink communication via a single 5G Wi-Fi band to downlink communication via a dual-band aggregation of 2.4G Wi-Fi and 5G Wi-Fi, and receives different target communication data through the two bands respectively, it is equivalent to merging the two target communication data streams. This effectively enhances the energy intensity of the received signal, effectively improving downlink reception quality and thus enhancing downlink coverage.

[0078] In this embodiment, when the communication resources of the radio frequency system are less than the preset communication resource requirements when performing single-channel single-band communication through the first target frequency band, and the first target frequency band is the second working frequency band, the radio frequency system is controlled to perform dual-band aggregation communication through the first working frequency band and the second working frequency band respectively, and different target communication data are transmitted through the first working frequency band and the second working frequency band respectively. This can improve the communication resources of the radio frequency system and enhance the communication quality of the radio frequency system.

[0079] In one embodiment, if the communication quality does not meet the preset communication quality, the radio frequency system is controlled to perform target communication according to the frequency range of the first target frequency band, such as... Figure 3 As shown, it includes steps 302 and 304.

[0080] Step 302: When the communication resources of the radio frequency system for single-channel single-band communication through the first target frequency band are less than the preset communication resources, and the first target frequency band is the second working frequency band, control the radio frequency system to perform single-band communication with multiple spatial multiplexing through the first target frequency band.

[0081] In this context, the radio frequency system performing single-channel single-band communication through the first target frequency band can be understood as the radio frequency system operating in SISO mode, and the radio frequency system performing single-band communication with multiple spatial multiplexing can be understood as the radio frequency system operating in MIMO mode. For MIMO mode and SISO mode, please refer to the relevant descriptions in the above embodiments.

[0082] It is understandable that when the radio frequency system is in SISO mode, if the current first target frequency band is already the second working frequency band with more communication resources, but the communication resources of the radio frequency system still cannot meet the preset communication resource requirements, the SISO mode can be switched to MIMO mode to improve the signal communication resources of a single frequency band and the transmission reliability under uplink / downlink congestion scenarios. In this way, the power consumption that may exist when using dual-band aggregation can be reduced while matching the communication quality.

[0083] By controlling the radio frequency system to perform single-channel single-band communication through the first target frequency band when the communication resources are less than the preset communication resource requirements, and the first target frequency band is the second operating frequency band, the radio frequency system can be controlled to perform single-band communication with multiple spatial multiplexing through the first target frequency band. This can improve the communication resources of the radio frequency system and reduce the power consumption that may occur when using dual-band aggregation while matching the communication quality.

[0084] Step 304: When the communication resources of the radio frequency system are less than the preset communication resources when performing single-band communication with multiple spatial multiplexing through multiple first target frequency bands, and the first target frequency band is the second working frequency band, control the radio frequency system to perform dual-band signal aggregation communication through the first working frequency band and the second working frequency band, and transmit different target communication data through the first working frequency band and the second working frequency band respectively.

[0085] It is understandable that when the communication resources of the radio frequency system for single-band communication with multiplexing through the first target frequency band are still less than the preset communication resource requirements, and the first target frequency band is the second working frequency band, the steps in the above embodiments are repeated again to finally control the radio frequency system to perform dual-band aggregation communication.

[0086] In one embodiment, when the communication quality does not meet the preset communication quality, the radio frequency system is controlled to perform target communication according to the frequency range of the first target frequency band. The method further includes: when the communication resources of the radio frequency system performing single-band communication through the first target frequency band are less than the preset communication resources, and the first target frequency band is the first working frequency band, the radio frequency system is controlled to switch to performing single-band communication through the second working frequency band; and the second working frequency band is updated to the first target frequency band currently performing single-band communication.

[0087] Referring to the above embodiments, the communication resources of the radio frequency system operating in the second operating frequency band are greater than those operating in the first operating frequency band. Therefore, when the communication resources of the radio frequency system performing single-band communication through the first target frequency band are less than the preset communication resources, and the first target frequency band is the first operating frequency band, the radio frequency system can be controlled to switch to single-band communication through the second operating frequency band. The second operating frequency band is then updated to the first target frequency band currently used for single-band communication. The judgment on whether the communication resources meet the preset communication resource requirements is then repeated as described in the above embodiments. If it is determined that the coverage capability of the radio frequency system performing single-band communication through the second operating frequency band meets the preset communication resource requirements, then the radio frequency system continues to perform single-band communication through the second operating frequency band. This reduces the energy consumption of dual-band communication and lowers communication costs while ensuring that the communication resource requirements are met. If the communication resources of the radio frequency system are still less than the preset communication resource requirements, the radio frequency system is controlled to perform dual-band communication to improve communication quality.

[0088] It should be noted that the above embodiments describe switching from single-band communication of the radio frequency system to single-band communication or dual-band aggregated communication of another frequency band. It can be understood that the above scheme is also applicable to switching to more frequency band aggregated communication and switching from dual-band aggregated communication to single-band communication. When the communication quality of any frequency band in the multi-band meets the preset requirements, the multi-band aggregated communication can be switched to single-band communication. The relevant judgment can be referred to the above embodiments.

[0089] Based on the same inventive concept, embodiments of this application also provide a communication control device, radio frequency system, and electronic device for implementing the communication control method described above. The solution provided by this device, radio frequency system, and electronic device is similar to the implementation scheme described in the communication control method above. Therefore, the specific limitations of one or more embodiments of the communication control device, radio frequency system, and electronic device provided below can be found in the limitations of the communication control method above, and will not be repeated here.

[0090] In one of the embodiments, such as Figure 4 As shown, a communication control device is provided for use in a radio frequency system, which communicates via at least one of a first operating frequency band and a second operating frequency band. The communication control device includes an acquisition module 402 and a control module 404.

[0091] The acquisition module 402 is used to acquire the current communication quality of the radio frequency system when the radio frequency system is conducting single-band communication through the first target frequency band, wherein the first target frequency band is the first or second operating frequency band currently conducting communication.

[0092] The control module 404 is used to control the radio frequency system to perform target communication according to the frequency range of the first target frequency band when the communication quality does not meet the preset communication quality.

[0093] The target communication includes either switching the radio frequency system to single-band communication via the second target frequency band or dual-band aggregation communication via the first and second working frequency bands; the second target frequency band is a frequency band in the first and second working frequency bands that is different from the first target frequency band.

[0094] The communication control device provided in this embodiment obtains the current communication quality of the radio frequency system when the radio frequency system is performing single-band communication through the first target frequency band; when the communication quality does not meet the preset communication quality, it controls the radio frequency system to perform target communication according to the frequency range of the first target frequency band, so that the radio frequency system switches to single-band communication through the second target frequency band, or performs dual-band aggregation communication through the first and second working frequency bands. This can improve the communication quality of the radio frequency system and electronic equipment, dynamically match communication needs, and improve the user experience.

[0095] In one of the embodiments, such as Figure 5 As shown, the radio frequency system includes: a first radio frequency circuit 10, a second radio frequency circuit 20, and a detection and control circuit 50.

[0096] One of the first RF circuit 10 and the second RF circuit 20 supports a first operating frequency band, and the other supports a second operating frequency. The RF system is used for communication via at least one of the first and second operating frequency bands. For example, the first RF circuit 10 and the second RF circuit 20 respectively support uplink communication, and each of the first RF circuit 10 and the second RF circuit 20 may include a power amplifier (PA) and a filter (SAW). The first RF circuit 10 and the second RF circuit 20 respectively support power amplification and filtering of the corresponding frequency band signals transmitted by each other. And / or, for example, the first RF circuit 10 and the second RF circuit 20 respectively support downlink communication, and each of the first RF circuit 10 and the second RF circuit 20 may include a low-noise amplifier (LNA) and a filter. The first RF circuit 10 and the second RF circuit 20 respectively support low-noise amplification and filtering of the corresponding frequency band signals transmitted by each other.

[0097] For example, the first RF circuit 10 and the second RF circuit 20 can be discrete devices or integrated devices. For example, when the first RF circuit 10 and the second RF circuit 20 are packaged as integrated devices, the first RF circuit 10 and the second RF circuit 20 can be understood as FEM devices. Furthermore, taking the WIFI standard as an example, the RF device can be a WIFIFEM, that is, a front-end integrated module for WIFI.

[0098] For example, the number of first radio frequency circuits 10 and second radio frequency circuits 20 can each be multiple, enabling the radio frequency system to support both MIMO and SISO modes. For example, any first radio frequency circuit 10 and any second radio frequency circuit 20 can form a circuit group to transmit signals through the same antenna during dual-band communication.

[0099] The detection and control circuit 50 is used to acquire the current communication quality of the radio frequency system when the radio frequency system is performing single-band communication through a first target frequency band, where the first target frequency band is either the first or second operating frequency band currently used for communication; and to control the first radio frequency circuit 10 and the second radio frequency circuit 20 to perform target communication according to the frequency range of the first target frequency band when the communication quality does not meet the preset communication quality. Target communication includes either switching the radio frequency system to single-band communication through the second operating frequency band or performing dual-band aggregated communication through the first and second operating frequency bands, where the second target frequency band is a frequency band different from the first target frequency band among the first and second operating frequency bands. Specifically, when the first and second operating frequency bands perform dual-band aggregated communication, such as... Figure 5As shown, the radio frequency system may also include a combiner 30, and the relevant description of the combiner is given in the above embodiment.

[0100] For example, the detection control circuit 50 can perform the steps of the communication control method in the above embodiments. The descriptions of the relevant functions of the first radio frequency circuit 10, the second radio frequency circuit 20, and the detection control circuit 50 can be found in the above embodiments and will not be repeated here.

[0101] The radio frequency system provided in this embodiment obtains the current communication quality of the radio frequency system when it is communicating in a single frequency band through a first target frequency band; when the communication quality does not meet the preset communication quality, it controls the radio frequency system to perform target communication according to the frequency range of the first target frequency band, so that the radio frequency system switches to communicating in a single frequency band through a second target frequency band, or to performing dual-band aggregated communication through the first and second working frequency bands. This can improve the communication quality of the radio frequency system and electronic equipment, dynamically match communication needs, and improve the user experience.

[0102] In one of the embodiments, such as Figure 5 As shown, the detection control circuit 50 includes: an RF transceiver 510 and a detection control module 520.

[0103] The radio frequency transceiver 510 is connected to the first radio frequency circuit 10 and the second radio frequency circuit 20, respectively. It is used to output a transmit signal to the first radio frequency circuit 10 and the second radio frequency circuit 20 during uplink communication, and / or to receive the receive signal transmitted by the first radio frequency circuit 10 and the second radio frequency circuit 20 during downlink communication. The radio frequency transceiver 510 can provide the transmit signal to the first radio frequency circuit 10 and the second radio frequency circuit 20 supporting uplink, allowing the two radio frequency circuits to perform power amplification and filtering on the transmit signal; it can also receive the receive signal after low-noise amplification and filtering by the first radio frequency circuit 10 and the second radio frequency circuit 20 supporting downlink.

[0104] The detection and control module 520, connected to the RF transceiver 510, is used to acquire the current communication quality of the RF system when the RF system is performing single-band communication through the first target frequency band. If the communication quality does not meet the preset communication quality, it outputs control commands to the RF transceiver 510 according to the frequency range of the first target frequency band. The detection and control module 520 can monitor the communication quality of the first RF circuit 10 and the second RF circuit 20 in the RF system. Figure 5The dashed line in the middle shows the optional monitoring path for the detection control module 520 to monitor the communication quality. The detection control module 520 can monitor the signal transmitted by the radio frequency circuit through this path to obtain the communication quality. If the communication quality does not meet the preset communication quality, the module obtains the frequency range of the first target frequency band, determines the control strategy based on the frequency range of the first target frequency band, and outputs control commands to the radio frequency transceiver 510.

[0105] The control commands instruct the RF transceiver 510 to control the first RF circuit 10 and the second RF circuit 20 for target communication. When the target communication is single-band communication, the RF transceiver 510 controls one of the first RF circuit 10 and the second RF circuit 20 to communicate. When the target communication is dual-band aggregation communication, the RF transceiver 510 controls the first RF circuit 10 and the second RF circuit 20 to be connected to the same antenna through the combiner 30 for dual-band aggregation communication. Based on the received control commands, the RF transceiver 510 can output a signal to be transmitted or a signal to be received, and can also control the enable state and operating parameters of the first RF circuit 10 and the second RF circuit 20 to control the first RF circuit 10 and the second RF circuit 20 to perform single-band communication or dual-band aggregation communication.

[0106] For example, such as Figure 6 As shown, the radio frequency system may also include a combiner 30. When dual-band aggregation communication is required, the radio frequency transceiver 510 can control the first radio frequency circuit 10 and the second radio frequency circuit 20 to be connected to the same antenna through the combiner 30, and perform dual-band aggregation communication through the same antenna.

[0107] The detection control circuit 50 in this embodiment, through the radio frequency transceiver 510 and the detection control module 520, can switch between single-band communication and dual-band communication of the first radio frequency circuit 10 and the second radio frequency circuit 20 to match communication quality requirements, improve the communication quality of the radio frequency system, and enhance the user experience.

[0108] In one of the embodiments, such as Figure 7 As shown, the first radio frequency circuit 10 includes a first radio frequency module 110 and a first coupling module 120, and the second radio frequency circuit 20 includes a second radio frequency module 210 and a second coupling module 220. Either the first radio frequency module 110 or the second radio frequency module 210 supports a first operating frequency band, and the other supports a second operating frequency band.

[0109] The first coupling module 120 is connected to the first radio frequency module 110 and the antenna, respectively, and is used to couple the signals transmitted between the first radio frequency module 110 and the antenna when the first radio frequency module 110 is communicating, so as to output a coupled signal. The second coupling module 220 is connected to the second radio frequency module 210 and the antenna, respectively, and is used to couple the signals transmitted between the second radio frequency module 210 and the antenna when the second radio frequency module 210 is communicating, so as to output a coupled signal. The first coupling module 120 and the second coupling module 220 can each be a coupler.

[0110] The detection and control module 520 is connected to the first coupling module 120, the second coupling module 220, and the radio frequency transceiver 510, respectively. It is used to obtain the transmit power and / or signal strength of the first target frequency band during uplink communication based on the coupling signal, and to obtain the uplink communication quality of the first target frequency band based on the transmit power and / or signal strength; and / or, to obtain the signal strength of the first target frequency band during downlink communication based on the coupling signal, and to obtain the downlink communication quality of the first target frequency band based on the signal strength. The detection and control module 520 is also used to obtain the frequency range of the first target frequency band based on communication with the radio frequency transceiver 510, and to output control commands to the radio frequency transceiver 510 according to the frequency range of the first target frequency band when the communication quality does not meet the preset communication quality.

[0111] The first coupling module 120 and the second coupling module 220 can respectively couple the radio frequency signals transmitted on the connected radio frequency circuits and output the coupling signal to the detection and control module 520. The detection and control module 520 can obtain the power information and signal strength of the radio frequency signals transmitted by each radio frequency circuit based on the coupling signal. The power information can include forward coupling power and reverse reflection power. Then, the detection and control module 520 can obtain the communication quality of the radio frequency system based on the power information and signal strength, and compare the communication quality with the preset communication requirements. Based on the comparison result, the first radio frequency circuit 10 and the second radio frequency circuit 20 can be controlled to perform target communication.

[0112] For example, the detection control module 520 can determine the limitation of the network coverage capability of the radio frequency system when the transmit power is greater than or equal to a power threshold and / or the signal strength is less than or equal to a receive threshold. Specifically, when the radio frequency system is performing uplink communication, it is determined that the uplink of the radio frequency system is limited when the transmit power is greater than or equal to the power threshold and / or the signal strength is less than or equal to the receive threshold; when the radio frequency system is performing downlink communication, it is determined that the downlink of the radio frequency system is limited when the signal strength is less than or equal to the receive threshold.

[0113] For example, when the transmit power is less than a power threshold and / or the signal strength is greater than a receive threshold, it is determined that the communication resources available for communication transmission in the radio frequency system are limited. Specifically, when the radio frequency system is performing uplink communication, if the transmit power is less than the power threshold and / or the signal strength is greater than the receive threshold, it is determined that the uplink resources of the radio frequency system are limited, i.e., uplink congestion; when the radio frequency system is performing downlink communication, if the signal strength is greater than the receive threshold, it is determined that the downlink resources of the radio frequency system are limited, i.e., downlink congestion.

[0114] For example, such as Figure 8 As shown, the detection control module 520 includes a detection unit 521 and a control unit 522.

[0115] The detection unit 521 can be connected to the first coupling module 120 and the second coupling module 220 respectively to obtain communication quality through the coupling signal. For example, the detection unit 521 includes a detector and a low-noise amplifier. The low-noise amplifier is connected between the detector and the control unit 522. The detector is used to acquire the coupling signal, and the low-noise amplifier is used to amplify the coupling signal before inputting it to the control unit 522. The control unit 522 calculates the corresponding transmission power and signal parameter values, such as signal strength values, based on the amplified coupled signal.

[0116] A detector, also known as a phase detector or demodulator, is an electronic circuit or device used to extract the raw information signal from a modulated signal. It has wide applications in wireless communication, radar, audio amplifiers, and other fields. The main function of a detector is to convert modulated signals (such as AM, FM, PM, etc.) into low-frequency baseband signals for further processing or direct use.

[0117] For example, the control unit 522 may include a microcontroller, microprocessor, single-chip microcomputer, digital signal processor, or other processor.

[0118] For example, such as Figure 9 The detection control module 520 may further include an instruction conversion unit 523, which is connected to the radio frequency transceiver 510. The instruction conversion unit 523 parses the MIPI instructions input from the radio frequency transceiver 510 to transmit instructions from the radio frequency transceiver 510 to the control unit 522, or transmits control instructions generated by the control unit 522 based on the frequency range of the first target frequency band to the radio frequency transceiver 510. For example, the control unit 522 obtains the MIPI instructions output by the radio frequency transceiver 510 to each radio frequency circuit based on the instruction conversion unit 523 to obtain the frequency range of the first target frequency band; for example, the control unit 522 can obtain the frequency range of the first target frequency band based on the MIPI instructions transmitted from the radio frequency transceiver 510 by the instruction conversion unit 523.

[0119] For example, the detection and control module 520 can integrate an RF chip to detect the communication quality of the first RF circuit 10 and the second RF circuit 20, the frequency range of the first target frequency band, determine the communication strategy for controlling the first RF circuit 10 and the second RF circuit 20, and control the communication status of the first RF circuit 10 and the second RF circuit 20 in reverse by feeding back the communication strategy to the RF transceiver 510.

[0120] The above embodiments will be further explained below with reference to some optional first radio frequency circuit 10, second radio frequency circuit 20, and detection control circuit 50:

[0121] Comparative Example 1

[0122] like Figure 10 As shown, the radio frequency system includes a first radio frequency circuit 10 and a second radio frequency circuit 20. The first radio frequency circuit 10 and the second radio frequency circuit 20 communicate in dual WIFI bands through a combiner 30. One radio frequency circuit supports 2.4G WIFI and BT, while the other radio frequency circuit supports 5G WIFI. The 2.4G / 5G / BT antennas are combined together, and the frequencies between 2.4G and 5G are separated by the combiner 30 and fed into the corresponding FEM devices at the back end, ultimately reaching the radio frequency transceiver 510.

[0123] 2.4G WIFI:

[0124] Transmit path: The signal from the RF transceiver 510 enters the 2.4G WIFI FEM, which contains a PA. The amplified signal passes through the internal SAW (filter) and is then output to the antenna by a switch. Receive path: The signal received by the antenna enters the internal FEM from the antenna port. There are two paths: strong signals enter the RF transceiver 510 directly through the Bypass path, while weak signals are filtered by the SAW and then amplified by the LNA before entering the internal RF transceiver 510.

[0125] BT pathway:

[0126] Transmit path: The signal from the RF transceiver 510 enters the FEM of the 2.4G WIFI, which has PA amplification and bypass mode. The amplified signal passes through the internal SAW (filter) and is then output to the antenna by the switch. Receive path: The signal received by the antenna enters the internal FEM from the antenna port and is directly output to the RF transceiver 510 through the internal pass-through RX port.

[0127] 5G WIFI:

[0128] Transmit path: The signal from the RF transceiver 510 enters the FEM of the 5G WIFI, which has two stages of amplifiers: LPM (low gain mode) and MPM / HPM (medium-high gain mode). The amplified signal passes through the internal SAW (filter) and is then output to the antenna by a switch. Receive path: The signal received by the antenna enters the internal FEM from the antenna port. There are two paths: strong signals enter the RF transceiver 510 directly through the bypass path, while weak signals are amplified by the LNA after passing through the SAW before entering the internal RF transceiver 510.

[0129] In this RF system, the dual-WIFI experience is mainly based on being on and off. There is no solution for dynamic switching based on user experience and indicators such as 2.4G / 5G frequency band, single-band communication, dual-band communication and communication quality. The experience of simply being on and off is relatively rigid.

[0130] Example 1 of this application

[0131] like Figure 11 As shown, based on the comparative embodiment, a detection control circuit 50 is added. When the radio frequency system is performing single-band communication through the first target frequency band, the detection control circuit 50 obtains the current communication quality of the radio frequency system. When the communication quality does not meet the preset communication quality, the first radio frequency circuit 10 and the second radio frequency circuit 20 are controlled to perform target communication according to the frequency range of the first target frequency band.

[0132] Taking upstream communication as an example, the communication control process of the detection control circuit 50 includes:

[0133] (1) When the radio frequency system is operating in 2.4G or 5G single-band communication, the transmission power or signal quality of the radio frequency circuit currently performing single-band communication is coupled and monitored through each coupling module: the coupling signal of the coupling module is obtained, and the transmission power and signal strength are detected.

[0134] (2) When it is determined that the transmission power is high or the signal strength is weak, it is determined that the uplink coverage is limited.

[0135] (3) When it is determined that the uplink coverage is limited, if the current first target frequency band is the 2.4G frequency band, the first radio frequency circuit 10 and the second radio frequency circuit 20 are controlled to work in the dual-band aggregation communication of the 2.4G frequency band and the 5G frequency band respectively. The dual-band signals are respectively used to transmit the same target communication data to enhance the uplink coverage; otherwise, switch to 2.4G for single-band communication for a second judgment.

[0136] (4) When it is determined that the transmission power is low or the signal strength is strong, it is determined to be uplink congestion.

[0137] (5) When it is determined that there is uplink congestion, if the current first target frequency band is the 5G frequency band, the first radio frequency circuit 10 and the second radio frequency circuit 20 are controlled to work in the 2.4G frequency band and the 5G frequency band respectively for dual-band aggregation communication. The dual-band signals are respectively used to transmit different target communication data to enhance the uplink bandwidth; otherwise, switch to 5G for single-band communication for secondary judgment.

[0138] (6) During single-band communication, continue to monitor the transmission status of the first radio frequency circuit 10 and the second radio frequency circuit 20 to form the state switch of the next timing sequence.

[0139] Example 2 of this application

[0140] like Figure 12 As shown, based on Embodiment 1 of this application, the number of the first radio frequency circuit 10 and the second radio frequency circuit 20 is increased, enabling the radio frequency system to support MIMO mode and SISO mode. The detection control circuit 50 obtains the current communication quality of the radio frequency system when the system is performing single-band communication through the first target frequency band; if the communication quality does not meet the preset communication quality, it controls the first radio frequency circuit 10 and the second radio frequency circuit 20 to perform target communication according to the frequency range of the first target frequency band.

[0141] Taking upstream communication as an example, the communication control process of the detection control circuit 50 includes:

[0142] (1) When the radio frequency system is operating in 2.4G or 5G single-band communication, the transmission power or signal quality of the radio frequency circuit currently performing single-band communication is coupled and monitored through each coupling module: the coupling signal of the coupling module is obtained, and the transmission power and signal strength are detected.

[0143] (2) When it is determined that the transmission power is high or the signal strength is weak, it is determined that the uplink coverage is limited.

[0144] (3) When it is determined that the uplink coverage is limited, if the current first target frequency band is the 2.4G frequency band, then it is further determined whether to perform SISO mode; otherwise, switch to 2.4G for single-band communication and make a second judgment.

[0145] (4) When it is determined to be SISO mode and the uplink coverage is limited, the first radio frequency circuit 10 and the second radio frequency circuit 20 are controlled to work in the 2.4G band and the 5G band respectively for dual-band aggregation communication. The dual-band signals are respectively transmitted to the same target communication data to enhance uplink coverage. If it is determined to be MIMO mode, it returns to SISO mode and is re-determined.

[0146] (5) When it is determined that the transmission power is low or the signal strength is strong, it is determined to be uplink congestion.

[0147] (6) When it is determined that there is uplink congestion, if the current first target frequency band is the 5G frequency band, then it is further determined whether to perform MIMO mode; otherwise, switch to 5G for single-band communication and make a second judgment.

[0148] (7) When it is determined to be MIMO mode and the uplink resources are limited, the first radio frequency circuit 10 and the second radio frequency circuit 20 are controlled to work in the 2.4G band and the 5G band respectively for dual-band aggregation communication. The dual-band signals are respectively used to transmit different target communication data to enhance the uplink bandwidth. When it is determined to be SISO mode, it returns to MIMO mode and re-determines.

[0149] (8) During single-band communication, continue to monitor the transmission status of the first radio frequency circuit 10 and the second radio frequency circuit 20 to form the state switch of the next timing sequence.

[0150] Compared to Comparative Example 1, Embodiments 1 and 2 of this application can improve the communication quality of the radio frequency system, dynamically match communication needs, and enhance the user experience.

[0151] This application also provides an electronic device including the radio frequency system described in any or more of the above embodiments or combined embodiments. Based on the radio frequency system, the electronic device can improve communication quality and enhance user experience.

[0152] like Figure 13 As shown, further explanation will be given using the aforementioned radio frequency system as an example of mobile phone 11. Specifically, as follows... Figure 13 As shown, the mobile phone 11 may include a memory 21 (which optionally includes one or more computer-readable storage media), a processor 22, a peripheral device interface 23, a radio frequency system 24 as described in the above embodiments, and an input / output (I / O) subsystem 26. These components optionally communicate via one or more communication buses or signal lines 29. Those skilled in the art will understand that... Figure 13 The mobile phone 11 shown does not constitute a limitation on the mobile phone and may include more or fewer components than shown, or combine certain components, or have different component arrangements. Figure 13 The various components shown are implemented in hardware, software, or a combination of both, including one or more signal processing and / or dedicated integrated modules.

[0153] Memory 21 optionally includes high-speed random access memory, and also optionally includes non-volatile memory, such as one or more disk storage devices, flash memory devices, or other non-volatile solid-state memory devices. Exemplary examples include software components stored in memory 21 such as an operating system 211, a communication module (or instruction set) 212, a global positioning system (GPS) module (or instruction set) 213, etc.

[0154] Processor 22 and other control modules (such as the control modules in the radio frequency system 24) can be used to control the operation of mobile phone 11. The processor 22 may be based on one or more microprocessors, microcontrollers, digital signal processors, baseband processors, power management units, audio codec chips, dedicated integrated modules, etc.

[0155] The processor 22 can be configured to implement control algorithms for controlling the use of the antenna in the mobile phone 11. The processor 22 can also issue control commands for controlling various switches in the radio frequency system 24.

[0156] I / O subsystem 26 couples input / output peripherals on mobile phone 11, such as a keypad and other input control devices, to peripheral interface 23. I / O subsystem 26 optionally includes a touchscreen, buttons, a tone generator, an accelerometer (motion sensor), an ambient light sensor and other sensors, LEDs and other status indicators, data ports, etc. For example, a user can control the operation of mobile phone 11 by supplying commands via I / O subsystem 26, and can use the output resources of I / O subsystem 26 to receive status information and other outputs from mobile phone 11.
