A short-range wireless communication system

[0001] Cross-reference to related applications

[0002] This application claims priority to Chinese Patent Application No. 202411505189.X, filed on October 25, 2024, entitled "A Short-Range Wireless Communication System", the entire contents of which are incorporated herein by reference. Technical Field

[0003] This application relates to the field of communication technology, and in particular to a short-range wireless communication system. Background Technology

[0004] Short-range wireless communication technology effectively simplifies communication between terminal devices such as computers, laptops, mobile phones, headphones, and speakers, as well as between these devices and networks. This allows small, portable, or wearable audio devices to connect to the network without cables, creating a point-to-multipoint communication system. Bluetooth (BT), a typical short-range wireless communication technology, has a wide range of applications due to its ability to enable bidirectional voice and data communication.

[0005] Taking a mobile phone as the terminal device and a true wireless stereo (TWS) earphone as the audio device, when the mobile phone sends audio data to the TWS earphone, it will use the same frequency domain resources to send the left channel data to the left earphone and the right channel data to the right earphone in turn. When the amount of data transmitted is large, the audio transmission period will occupy more time in the communication cycle and consume more air interface resources, which will reduce the chance of data retransmission and thus affect the anti-interference ability of data transmission. Summary of the Invention

[0006] This application provides a short-range wireless communication system to improve data transmission rate and anti-interference capability.

[0007] In a first aspect, embodiments of this application provide a short-range wireless communication system, which includes a terminal device and at least one audio device. The terminal device establishes a short-range connection with the at least one audio device. The terminal device is used to: in response to receiving a data transmission command, simultaneously transmit the same type of short-range communication data to the at least one audio device using different frequency domain resources in short-range communication. Because the same type of short-range communication data is transmitted simultaneously to at least one audio device using different frequency domain resources, the communication time between the terminal device and any audio device can be reduced. Compared with the prior art of sequentially transmitting the same type of short-range communication data using the same frequency domain resources, this effectively reduces the occupation of air interface resources, improves air interface transmission efficiency, increases retransmission opportunities, and thus improves the data transmission rate and anti-interference capability.

[0008] Optionally, at least one audio device includes at least one of other smart home devices or smart terminals with short-range communication and audio playback functions, such as TWS earphones, speakers, etc. For example, but not limited to: at least one audio device is a TWS earphone; or at least one audio device is multiple speakers; or at least one audio device is a TWS earphone and at least one speaker; the specific configuration can be set according to actual needs and is not specifically limited here.

[0009] Optionally, the short-range connection includes either Bluetooth or StarFlash connection. When the terminal device has Bluetooth functionality, the short-range connection is a Bluetooth connection, and the transmitted data is Bluetooth data. When the terminal device has StarFlash functionality, the short-range connection is a StarFlash connection, and the transmitted data is StarFlash data. The terminal device can have both Bluetooth and StarFlash functionality simultaneously; in this case, Bluetooth and StarFlash connections can be performed concurrently or separately. The specific configuration can be determined according to actual needs and is not specifically limited here.

[0010] Furthermore, the communication cycle between the terminal device and the audio device includes an audio transmission period and a retransmission period. The audio transmission period is used for the terminal device to send data to at least one audio device, and the retransmission period is used for the terminal device to retransmit data to any audio device. The terminal device is also used to receive mobile hotspot Wi-Fi data during the retransmission period. Thus, by improving the audio data transmission mechanism, the duration of the retransmission period can be increased. This provides more time for Wi-Fi services even when transmitting large amounts of audio data, ensuring the normal operation of Wi-Fi services and effectively improving the coexistence experience of Bluetooth (or StarFlash) and Wi-Fi.

[0011] Optionally, in order to simultaneously transmit the same type of short-range communication data to at least one audio device through different frequency domain resources in short-range communication, the following specific implementation methods can be adopted:

[0012] Method 1: Multiple audio devices are used. The terminal device is specifically used to simultaneously send different channel data to multiple audio devices via different frequency domain resources in short-range communication. When both left and right channel data are multiple, the left channel data is sent sequentially, and the right channel data is sent sequentially. Regardless of the type of channel data, the simultaneously sent different channel data belong to the same category of short-range communication data. This reduces air interface resource usage, improves air interface transmission efficiency, increases retransmission opportunities, and enhances data transmission rate and anti-interference capabilities.

[0013] The different frequency domain resources include at least two of the following: the 2.4GHz band, the 5GHz band, or the 6GHz band, or other unlicensed frequency bands. It should be understood that unlicensed frequency bands refer to frequency bands that can be used without obtaining a license. The specific settings can be configured according to actual needs and are not specifically limited here.

[0014] Method 2: Multiple audio devices are used. Specifically, the terminal device simultaneously sends the same channel data to any one audio device via different frequency domain resources in short-range communication, and alternately sends different channel data to different audio devices. By sending the same channel data simultaneously through different frequency domain resources, the transmission bandwidth of each channel data is increased, thereby shortening the communication time of each channel data, i.e., shortening the communication window duration, increasing the data throughput rate, further improving air interface transmission efficiency, and thus further improving data transmission rate and anti-interference capability.

[0015] The different frequency domain resources include: different frequency domain resources in the 2.4GHz band, different frequency domain resources in the 5GHz band, or different frequency domain resources in the 6GHz band, as well as other unlicensed frequency domain resources. Alternatively, the different frequency domain resources include at least two of the 2.4GHz band, 5GHz band, and 6GHz band. The specific settings can be configured according to actual needs and are not specifically limited here.

[0016] Method 3: An audio device is provided, and a terminal device is specifically used to simultaneously send different first data to the audio device through different frequency domain resources in short-range communication. The first data can be, but is not limited to, file data, image data, video data, or audio data without channel splitting (such as stereo data), etc. Regardless of the implementation form of the first data, the different first data sent at the same time belong to the same type of short-range communication data. Thus, the occupation of air interface resources can also be reduced, air interface transmission efficiency can be improved, retransmission opportunities can be increased, and data transmission rate and anti-interference ability can be improved.

[0017] In this method 3, the setting method of different frequency domain resources is similar to that in the aforementioned method 2. For details, please refer to the relevant description in the aforementioned method 2, which will not be elaborated here.

[0018] Method 4: The audio device has one terminal device specifically used to simultaneously send the same first data to the audio device through different frequency domain resources in short-range communication, with different first data being sent sequentially. Because the same first data is sent simultaneously through different frequency domain resources, the transmission bandwidth of each first data is increased, thereby shortening the communication time of each first data, i.e., shortening the communication window duration, increasing the data throughput rate, and further improving the air interface transmission efficiency, thus further improving the data transmission rate and anti-interference capability. The implementation form of the first data is similar to that in Method 3 mentioned above, and will not be detailed here.

[0019] In this method 4, the setting method for different frequency domain resources is similar to that in the aforementioned method 2. For details, please refer to the relevant description in the aforementioned method 2, which will not be elaborated here.

[0020] In summary, during implementation, a suitable implementation method can be selected from methods 1 to 4 above, depending on the needs of the scenario, to meet the requirements of different application scenarios. It should be understood that when there are multiple audio devices, the specific number of audio devices is not limited in this embodiment; the number of audio devices can be two, three, four, or more, and can be set according to the actual situation.

[0021] Secondly, embodiments of this application also provide a communication method for a short-range wireless communication system, the short-range wireless communication system including a terminal device and at least one audio device; the communication method includes: the terminal device establishing a short-range connection with at least one audio device; and the terminal device, in response to receiving a data transmission command, simultaneously sending the same type of short-range communication data to at least one audio device through different frequency domain resources in the short-range communication. Thus, by simultaneously sending the same type of short-range communication data to at least one audio device through different frequency domain resources, the communication time between the terminal device and any audio device can be reduced. Compared with the prior art of sequentially sending the same type of short-range communication data through the same frequency domain resources, this effectively reduces the occupation of air interface resources, improves air interface transmission efficiency, increases retransmission opportunities, and thereby improves the data transmission rate and anti-interference capability.

[0022] It should be understood that since the principle of this communication method in solving the problem is similar to that of the aforementioned short-range wireless communication system, the implementation and technical effects of this communication method can be found in the implementation and technical effects of the aforementioned short-range wireless communication system, and the repetitions will not be repeated.

[0023] Thirdly, embodiments of this application also provide a terminal device, comprising: a processor and a plurality of antennas, the processor being coupled to the plurality of antennas; the antennas are used for: establishing short-range connections with at least a portion of at least one audio device, and transmitting data to the connected audio devices; wherein each antenna corresponds to at least one frequency domain resource in short-range communication; the processor is used for: in response to receiving a data transmission command, simultaneously transmitting the same type of short-range communication data to at least one audio device through different frequency domain resources of different antennas. Thus, by simultaneously transmitting the same type of short-range communication data to at least one audio device through different frequency domain resources, the communication time between the terminal device and any audio device can be reduced. Compared with the prior art of sequentially transmitting the same type of short-range communication data through the same frequency domain resource, this effectively reduces the occupation of air interface resources, improves air interface transmission efficiency, increases retransmission opportunities, and thereby improves data transmission rate and anti-interference capability.

[0024] Optionally, the communication cycle between the terminal device and the audio device includes an audio transmission period and a retransmission period. The audio transmission period is used for the terminal device to send data to at least one audio device, and the retransmission period is used for the terminal device to retransmit data to any audio device. Short-range connections include Bluetooth or Starlink connections. The antenna is also used to receive mobile hotspot Wi-Fi data during the retransmission period. Thus, by improving the audio data transmission mechanism, the duration of the retransmission period can be increased. This provides more time for Wi-Fi services even when transmitting large amounts of audio data, ensuring the normal operation of Wi-Fi services and effectively improving the coexistence experience of Bluetooth (or Starlink) and Wi-Fi.

[0025] Optionally, the processor is specifically configured to simultaneously transmit different channel data to at least one audio device using different frequency domain resources of different antennas. This reduces the occupation of air interface resources, improves air interface transmission efficiency, increases retransmission opportunities, and enhances data transmission rate and anti-interference capability.

[0026] Alternatively, the processor can be specifically configured to: simultaneously transmit the same channel data to at least one audio device using different frequency domain resources of different antennas, and sequentially transmit different channel data to any audio device. Because the same channel data is transmitted simultaneously using different frequency domain resources, the transmission bandwidth of each channel data is increased, thereby shortening the communication time of each channel data, i.e., shortening the communication window duration, increasing the data throughput rate, further improving air interface transmission efficiency, and thus further improving the data transmission rate and anti-interference capability.

[0027] Optionally, the processor may include multiple short-range communication modules and multiple radio frequency (RF) front-end modules. The short-range communication modules are configured and coupled to the RF front-end modules one-to-one, and the RF front-end modules are configured and coupled to the antennas one-to-one. The short-range communication modules can send RF signals carrying audio data to the corresponding RF front-end modules. The RF front-end modules filter, amplify, and process the received RF signals before transmitting them to the corresponding antennas. Finally, the processed RF signals are transmitted through the antennas, thereby realizing the transmission of audio data.

[0028] It should be understood that since the principle by which this terminal device solves the problem is similar to that of the aforementioned short-range wireless communication system, the implementation and technical effects of this terminal device can be found in the implementation and technical effects of the aforementioned short-range wireless communication system, and the repetitions will not be repeated.

[0029] Fourthly, embodiments of this application also provide a computer-readable storage medium storing a computer program that, when run on a computer, causes the computer to perform the communication method described in the second aspect above.

[0030] Fifthly, embodiments of this application also provide a computer program product that, when run on a computer, causes the computer to perform the communication method described in the second aspect above.

[0031] The technical effects that can be achieved by any of the fourth or fifth aspects mentioned above can be described with reference to the technical effects that can be achieved by any possible design in the first aspect mentioned above. The repetitions will not be discussed.

[0032] Sixthly, embodiments of this application also provide a radio frequency (RF) chip, which includes multiple short-range communication modules. Each short-range communication module is coupled to an antenna. Each short-range communication module transmits RF signals to its corresponding antenna. Different short-range communication modules correspond to different frequency domain resources, and the RF signals output by different short-range communication modules are simultaneously transmitted outward through their respective antennas. The simultaneously transmitted RF signals carry the same type of short-range communication data. Thus, by simultaneously transmitting the same type of short-range communication data to at least one audio device through different frequency domain resources, the communication time between the terminal device and any audio device can be reduced. Compared with the prior art of sequentially transmitting the same type of short-range communication data through the same frequency domain resources, this effectively reduces the occupation of air interface resources, improves air interface transmission efficiency, increases retransmission opportunities, and thereby improves data transmission rate and anti-interference capability.

[0033] For example, the radio frequency chip can be one of the processors described in the third aspect above. In specific implementation, the structure included in the radio frequency chip is not limited to the short-range communication module, but may also include other structures set according to actual needs, which are not specifically limited here.

[0034] When different short-range communication modules correspond to different frequency domain resources, there are two ways to configure the short-range communication modules and antennas: First, different short-range communication modules are coupled to different antennas, meaning different short-range communication modules correspond to different antennas. When the frequency domain resources of the antenna and the corresponding short-range communication module are the same, the frequency domain resources corresponding to different antennas will also be different, and each antenna can correspond to one frequency domain resource. Second, some short-range communication modules are coupled to different antennas, meaning some short-range communication modules correspond to different antennas. In this case, some short-range communication modules correspond to the same antenna. If this part of the short-range communication modules corresponding to the same antenna is called a multiplexed antenna, then when the frequency domain resources of the antenna and the corresponding short-range communication module are the same, the multiplexed antenna can correspond to multiple frequency domain resources, while the non-multiplexed antenna can correspond to one frequency domain resource.

[0035] Optionally, the short-range communication module may include a baseband unit and a radio frequency (RF) transceiver unit. The baseband unit is coupled to the RF transceiver unit, which is used to couple to a corresponding antenna. That is, the RF transceiver unit is coupled to the corresponding antenna through a corresponding RF front-end module. During signal transmission, the RF transceiver unit can modulate the mid-to-high frequency digital signal carrying audio data from the baseband unit into a high-frequency electromagnetic wave signal (i.e., an RF signal), and transmit this RF signal to the corresponding RF front-end module. The RF front-end module can perform power amplification and filtering on the RF signal, and then radiate the amplified and filtered RF signal through the antenna. During signal reception, the RF front-end module can perform filtering and low-noise amplification on the RF signal received by the antenna. The RF transceiver unit can demodulate the filtered and low-noise amplified RF signal into a mid-to-high frequency digital signal, and send the mid-to-high frequency digital signal to the baseband unit. This allows the extraction of information carried in the RF signal received through the antenna, thereby achieving short-range communication.

[0036] It should be understood that since the principle by which this radio frequency chip solves the problem is similar to that of the aforementioned short-range wireless communication system, the implementation and technical effects of this radio frequency chip can be found in the implementation and technical effects of the aforementioned short-range wireless communication system, and the repetitions will not be repeated.

Detailed Implementation

[0048] To make the objectives, technical solutions, and advantages of this application clearer, the application will now be described in further detail with reference to the accompanying drawings.

[0049] It should be noted that the same reference numerals in the accompanying drawings of this application denote the same or similar structures, and therefore repeated descriptions of them will be omitted. Terms expressing position and direction described in this application are illustrative based on the accompanying drawings, but may be modified as needed, and all such modifications are included within the scope of protection of this application. The accompanying drawings of this application are for illustrating relative positional relationships only and do not represent actual scale.

[0050] The following explanations of some terms used in this application are provided to facilitate understanding by those skilled in the art.

[0051] 1. Short-range wireless communication technology is a communication technology that allows two parties to transmit information via radio waves within a relatively small range.

[0052] Short-range wireless communication technologies may include, but are not limited to: radio frequency identification (RFID) technology, Bluetooth technology, wireless-fidelity (wifi) technology, Starflash, ZigBee technology, ultra-wideband (UWB) technology, as well as communication technologies evolved from the above-mentioned communication technologies, and communication technologies with the same or similar functions as the above-mentioned communication technologies and which can be substituted for each other.

[0053] 2. A short-range wireless communication system is a communication system established by multiple devices through short-range wireless communication technology, which can be simply referred to as a communication system in this application embodiment. Specifically, depending on the specific communication technology used, it can be further divided into RFID systems, Bluetooth systems, Wi-Fi systems, etc.

[0054] Based on their role or function in the communication system, devices in the communication system can be defined into two types: terminal devices, which can also act as master devices, and audio devices, which can act as slave devices. In the following content, terminal devices and master devices can be used interchangeably, as can audio devices and slave devices.

[0055] The master device has communication links with all slave devices in the communication system, enabling it to control and manage all slave devices and conduct business communication with each slave device individually. All devices in the communication system other than the master device are slave devices.

[0056] Typically, a short-range wireless communication system has one master device and at least one slave device. In this embodiment, a short-range wireless communication system having one master device and at least one slave device is referred to as a short-range wireless communication system. It should be understood that in some communication scenarios, a short-range wireless communication system may also have multiple master devices.

[0057] Furthermore, for ease of description, short-range wireless communication can be simply referred to as short-range communication.

[0058] In the embodiments of this application, different short-range wireless communication systems transmit different types of short-range communication data. For example, Bluetooth data is transmitted in Bluetooth systems, Wi-Fi data is transmitted in Wi-Fi systems, and Star Flash data is transmitted in Star Flash systems, etc. Therefore, Bluetooth data, Wi-Fi data, and Star Flash data belong to different types of short-range communication data.

[0059] 3. Bluetooth system is a communication system established by at least two devices through Bluetooth technology. It can also be called Bluetooth network, communication network, micronet, or piconet. Devices in a Bluetooth system can also be called Bluetooth devices.

[0060] Based on their role in the Bluetooth system, two types of Bluetooth devices can be defined:

[0061] Master device: In a Bluetooth system, the Bluetooth device that actively initiates a connection request process, which includes device discovery, pairing initiation, and connection establishment. The master device can also be called the master controller. Additionally, the master device is responsible for providing clock synchronization signals and frequency hopping sequences to slave devices.

[0062] Slave device: A slave device in a Bluetooth system other than the master device, which is managed and controlled by the master device.

[0063] In a Bluetooth system, there is typically one Bluetooth device as the master device, and all other Bluetooth devices as slave devices, and this state remains unchanged for the duration of the Bluetooth system. Any slave device in a Bluetooth system can communicate with the master device, while the master device can communicate with multiple slave devices in the Bluetooth system.

[0064] 4. Terminal equipment, also known as main equipment, is a device that supports short-range wireless communication technology and provides users with voice and / or data connectivity.

[0065] Typically, terminal devices that serve as the main devices in short-range wireless communication systems are user-friendly devices with displays and integrated relatively complex algorithms (possessing management and control capabilities). Examples include, but are not limited to, mobile phones, tablets, laptops, handheld computers, virtual reality (VR) devices, augmented reality (AR) devices, wireless terminals in industrial control, and wireless terminals in self-driving vehicles.

[0066] 5. Audio devices, also known as slave devices, are typically small, portable, wearable devices capable of receiving and playing audio data. Examples include, but are not limited to, TWS earphones and speakers. Alternatively, audio devices can also be other smart home devices or smart terminals with short-range communication and audio playback capabilities. Of course, when multiple audio devices are included in a short-range wireless communication system, at least two of the following can be included: TWS earphones, speakers, smart home devices, and smart terminals.

[0067] 6. A communication link is a communication line between two adjacent communication nodes, without any other communication nodes in between; it is also called a communication connection, link, or connection. In the embodiments of this application, the communication links involved in the short-range wireless communication system are all wireless air interface connections (or simply air interface connections).

[0068] For example, in a Bluetooth system, a communication link established through Bluetooth technology can also be called a Bluetooth connection; in a StarScan system, a communication link established through StarScan technology can also be called a StarScan connection.

[0069] 7. Air interface resources are the resources required to realize wireless air interface transmission. They can also be called channel resources or channels, and may include, but are not limited to, time domain resources and frequency domain resources.

[0070] Among them, time domain resources refer to the continuous or discontinuous time used to achieve air interface transmission. Frequency domain resources refer to the continuous or discontinuous frequency bands used to achieve air interface transmission.

[0071] It should be noted that "multiple" in this application refers to two or more. "At least one" refers to one or more.

[0072] In addition, it should be understood that in the description of this application, the words "first" and "second" are used only for the purpose of distinguishing descriptions and should not be construed as indicating or implying relative importance or order.

[0073] The embodiments of this application will now be described in detail with reference to the accompanying drawings.

[0074] Figure 1 illustrates the architecture of a short-range wireless communication system provided in an embodiment of this application. Taking a mobile phone as the terminal device and TWS earphones as the audio devices, with the mobile phone and TWS earphones connected via Bluetooth as an example, as shown in Figure 1, the communication system includes a terminal device and multiple audio devices. For example, the left and right earphones shown in Figure 1 serve as audio devices, and the mobile phone serves as the terminal device. The mobile phone can establish temporary peer-to-peer communication links with multiple earphones, thereby establishing a short-range wireless communication system. The mobile phone can control and manage all earphones in the communication system and can conduct service communication with each earphone in the communication system. For example, the mobile phone can add or remove earphones in the communication system and allocate air interface resources to the earphones.

[0075] When sending audio data to TWS earbuds, mobile phones typically use a dual-transmission scheme. For example, the phone sends left channel data to the left earbud and right channel data to the right earbud. In this way, the left earbud only receives left channel data and the right earbud only receives right channel data. For a single earbud, only the data of a single channel needs to be decoded, which can improve data transmission efficiency and reduce the power consumption of the earbuds.

[0076] Referring to the timing diagram shown in Figure 2, the communication cycle T of a mobile phone generally includes an audio transmission period T1 and a retransmission period T2. The audio transmission period T1 is used for the mobile phone to send audio data to the headset. The audio transmission period T1 includes multiple communication windows. Within a communication window, the mobile phone sends an audio data packet to the left headset (or right headset). After receiving the audio data packet, the left headset (or right headset) sends a response back to the mobile phone. The mobile phone receives the response. The time t1 from when the mobile phone sends the audio data to when it receives the response can be called the communication window. The retransmission period T2 is used for the mobile phone to retransmit data to the headset. The retransmission period T2 includes a retransmission window C, and generally the duration of the communication window and the retransmission window C is the same. When a mobile phone sequentially sends data to the left and right earpieces using the same frequency domain resources, the left channel data L and the right channel data R each occupy a communication window. If data retransmission occurs, it needs to be done within the retransmission window C. When the amount of data transmitted is large and occupies a large bandwidth, the audio transmission period T1 will occupy a longer time within the communication cycle T, consuming more air interface resources. This will shorten the retransmission period T2 and reduce the chance of data retransmission. Since the anti-interference capability of data transmission is related to the retransmission chance, a decrease in the retransmission chance will reduce the anti-interference capability, and vice versa. The data transmission mechanism described above leads to a decrease in the chance of data retransmission, thus reducing the anti-interference capability of data transmission. To distinguish this from the data transmission mechanism mentioned below, the data transmission mechanism of "the mobile phone sequentially sending data to the left and right earpieces using the same frequency domain resources" mentioned in this paragraph can be referred to as the existing data transmission mechanism.

[0077] Based on this, embodiments of this application provide a communication scheme applied to a short-range wireless communication system. In this scheme, the short-range wireless communication system includes a terminal device and at least one audio device, and the terminal device establishes a short-range connection with the at least one audio device. The terminal device is used to: in response to receiving a data transmission command, simultaneously send the same type of short-range communication data to the at least one audio device through different frequency domain resources in short-range communication. Thus, by simultaneously sending the same type of short-range communication data to at least one audio device through different frequency domain resources, the communication time between the terminal device and any audio device can be reduced. Compared with the prior art of sequentially sending the same type of short-range communication data through the same frequency domain resources, this effectively reduces the occupation of air interface resources, improves air interface transmission efficiency, increases retransmission opportunities, and thereby improves the data transmission rate and anti-interference capability.

[0078] Figure 3 illustrates a schematic diagram of the architecture of a short-range wireless communication system according to an embodiment of this application. Referring to Figure 3, the short-range wireless communication system may include a terminal device (as indicated by 10 in Figure 1) and multiple audio devices. The terminal device establishes a short-range connection with the multiple audio devices. This short-range connection can be, but is not limited to, Bluetooth or Starlink connections. The terminal device can be a device with short-range communication capabilities, such as, but not limited to, a mobile phone 10, a tablet computer, etc. The multiple audio devices can be devices with both short-range communication and audio playback capabilities, such as, but not limited to, TWS earphones, speakers, smart home devices, smart terminals, etc. In this embodiment, the mobile phone 10 is used as the terminal device, the TWS earphones as multiple audio devices, and Bluetooth as the short-range connection for illustration. Therefore, the system consisting of the mobile phone 10 and the TWS earphones can be called a Bluetooth system. It should be understood that when there are multiple audio devices, the specific number of audio devices is not limited in this embodiment. The number of audio devices can be two, three, four, or more, and can be set according to the actual situation.

[0079] In this Bluetooth system, the process of connecting mobile phone 10 to TWS earphones can include: after turning on the Bluetooth function, mobile phone 10 can find Bluetooth devices near mobile phone 10 through the device search process; when mobile phone 10 finds TWS earphones, it displays the device identifier of the TWS earphones in the Bluetooth device list; when the user clicks on the device identifier of the TWS earphones in the Bluetooth device list to notify mobile phone 10 to connect to the TWS earphones, mobile phone 10 initiates pairing with the TWS earphones. After successful pairing, communication connections are established with the left and right earphones of the TWS earphones respectively, that is, a Bluetooth connection is established.

[0080] After the TWS earphones are connected to the phone 10, if the user selects the audio playback option in the phone 10's interface, the phone 10 can receive the data transmission command and send audio data to the TWS earphones. After receiving the audio data, the TWS earphones can process it accordingly to play the audio.

[0081] When mobile phone 10 sends audio data to TWS earphones, the following method can be used: Mobile phone 10 includes two antennas. One antenna (i.e., the first antenna 12a) establishes a Bluetooth connection with the left earphone, and the other antenna (i.e., the second antenna 12b) establishes a Bluetooth connection with the right earphone. The dotted line in Figure 3 represents the Bluetooth connection. Assuming that the first antenna 12a in mobile phone 10 uses frequency domain resource A when sending data, and the second antenna 12b uses frequency domain resource B when sending data, then mobile phone 10 can send left channel data L to the left earphone through frequency domain resource A, and at the same time send right channel data R to the right earphone through frequency domain resource B. This allows the left channel data L and right channel data R to be sent simultaneously through different frequency domain resources. In other words, the mobile phone sends different channel data to the left and right earphones simultaneously through different frequency domain resources. Furthermore, when there are multiple left channel data and multiple right channel data, each left channel data is sent sequentially, and each right channel data is sent sequentially. In this way, when the communication cycle T of mobile phone 10 includes an audio transmission period T1 and a retransmission period T2, with audio transmission period T1 used for mobile phone 10 to send audio data to the earphone and retransmission period T2 used for mobile phone 10 to retransmit data to the earphone, the audio transmission period T1 of mobile phone 10 within the communication cycle T only accounts for 1 / 4, and the remaining 3 / 4 is used as the retransmission period T2. Compared with the prior art where 1 / 2 of the communication cycle T is used as the retransmission period T2, the retransmission period T2 is increased by 25%, and the number of retransmissions of single-ear data increases from two in the prior art to three, effectively increasing the retransmission opportunity, improving the data transmission rate and anti-interference capability. Furthermore, compared with the prior art, the duration of the audio transmission period T1 is reduced, thereby reducing transmission latency, improving data transmission quality, and thus improving the audio playback quality of TWS earphones.

[0082] It should be understood that any given earphone may have one, two, or more antennas, and this is not limited here. Furthermore, the mobile phone 10 can also establish a Bluetooth connection with both the left and right earphones via a single antenna (referred to as antenna A). In this case, antenna A can be a multiplexed antenna, allowing it to correspond to multiple frequency domain resources. Thus, the mobile phone 10 can send left channel data L to the left earphone via one of the frequency domain resources corresponding to antenna A, and send right channel data R to the right earphone via another frequency domain resource corresponding to antenna A. This allows for the simultaneous transmission of different channel data to the left and right earphones via different frequency domain resources using a single antenna.

[0083] Of course, the timing diagrams shown in Figures 2 and 4 are for the case of transmitting lossless audio data. The same effect of reducing air interface resource usage can be achieved when transmitting high-definition audio data or ordinary audio data. Taking the transmission of high-definition audio as an example, as shown in Figure 5, Figure 5(a) shows the case of transmitting data using the existing technical solution, and Figure 5(b) shows the case of transmitting data using the technical solution in this application embodiment. Since the data transmission volume is lower than that of lossless audio data, the duration of a single communication will be shortened. In the prior art, because the same frequency domain resource (such as frequency domain resource A) is used to sequentially send left channel data L and right channel data R to the left and right earphones, therefore... The duration ratio of audio transmission period T1 to retransmission period T2 is approximately 1:2, with about four retransmission windows C. In this embodiment, due to the use of different frequency domain resources, such as frequency domain resource A and frequency domain resource B, the left channel data L is sent to the left earphone while the right channel data R is sent to the right earphone. Therefore, an additional retransmission window C is added within the communication period T, making the duration ratio of audio transmission period T1 to retransmission period T2 approximately 1:5, with about five retransmission windows C. This reduces the occupation of air interface resources, improves air interface transmission efficiency, and increases retransmission opportunities, thereby enhancing the anti-interference capability of data transmission in scenarios involving the transmission of high bitrate audio data or large data.

[0084] For example, frequency domain resource A can be other unlicensed frequency bands such as the 2.4GHz band, 5GHz band, or 6GHz band, and frequency domain resource B can also be other unlicensed frequency bands such as the 2.4GHz band, 5GHz band, or 6GHz band, such that different frequency domain resources include at least two of the 2.4GHz band, 5GHz band, and 6GHz band. For example, frequency domain resource A is the 2.4GHz band, and frequency domain resource B is the 5GHz band; or, frequency domain resource A is the 5GHz band, and frequency domain resource B is the 6GHz band; and so on. These will not be listed exhaustively here, and the specific settings can be configured according to actual needs, without specific limitations. It should be understood that unlicensed frequency bands refer to frequency bands that can be used without obtaining a license; the frequency range corresponding to the 2.4GHz band is 2.405GHz to 2.485GHz; the frequency range corresponding to the 5GHz band is 5.1GHz to 5.8GHz; and the frequency range corresponding to the 6GHz band is 6.0GHz to 6.4GHz.

[0085] Furthermore, when sending audio data to the two earphones, the mobile phone 10 can use frequency hopping technology. For example, taking the mobile phone 10 sending left channel data to the left earphone via the 2.4GHz band as an example, when sending the i-th left channel data to the left earphone, the mobile phone 10 can use the a-band in the 2.4GHz band. Then, when sending the (i+1)-th left channel data to the left earphone, it can use the b-band in the 2.4GHz band. The a-band and b-band are different but both belong to the 2.4GHz band, and i takes the value of a positive integer. In this way, the mobile phone 10 can use different frequency bands when sending each left channel data to the left earphone to ensure effective transmission of audio data and ensure the transmission quality of audio data.

[0086] The data transmission mechanism shown in Figure 4 can be called the first data transmission mechanism. This first data transmission mechanism is applicable to the following scenarios. For example, taking frequency domain resource A as the 2.4GHz band and frequency domain resource B as the 5GHz band as an example, when the number of transmission channels set in both the 2.4GHz and 5GHz bands is one, the left channel data can be transmitted through one transmission channel in the 2.4GHz band and the right channel data can be transmitted through one transmission channel in the 5GHz band. This reduces the hardware requirements of the mobile phone 10 and the manufacturing cost of the mobile phone 10 while ensuring normal audio data transmission. Alternatively, when one earphone is closer to the mobile phone 10 and the other earphone is farther away, the earphone that is farther away uses a lower frequency band, such as the 2.4GHz band, to transmit audio data, while the earphone that is closer uses a higher frequency band, such as the 5GHz band, to transmit audio data. Since the higher the frequency band and the greater the distance, the higher the loss, and vice versa, using a lower frequency band to transmit audio data when the distance is greater can reduce loss and thus improve the data transmission quality. Of course, the first data transmission mechanism can be applied to scenarios beyond the two listed above. It can also be applied to other scenarios, depending on actual needs. No specific limitations are made here.

[0087] In reality, the phone 10 not only has Bluetooth functionality, but can also have other functions such as, but not limited to, Wi-Fi functionality, allowing the phone 10 to have both Bluetooth and Wi-Fi functionality. Since Wi-Fi and Bluetooth operate on the same frequency band, they have to work in a time-sharing manner. However, Bluetooth services usually have a higher priority than Wi-Fi services, and Wi-Fi services are usually performed during retransmission periods. This means that when transmitting large amounts of data via Bluetooth, it will seriously affect the use of Wi-Fi services.

[0088] The technical solution provided in this application improves the audio data transmission mechanism by increasing the duration of the retransmission period T2. This allows for more transmission windows for Wi-Fi services even when Bluetooth and Wi-Fi operate in a time-sharing manner, and when transmitting large amounts of audio data via Bluetooth. Receiving Wi-Fi data within the retransmission period T2 provides a more efficient timeframe for Wi-Fi service, ensuring its normal operation and effectively improving the coexistence experience of Bluetooth and Wi-Fi. For example, as shown in Figure 4, when transmitting lossless data, the number of retransmission windows C is approximately three times the number of communication windows, providing more retransmission opportunities. Even if a retransmission occurs during retransmission period T2, there will still be some idle retransmission windows C available for Wi-Fi services. This avoids the situation in existing technologies where Wi-Fi services can only wait for the next communication cycle's retransmission window C when data retransmission occurs, thus improving the Wi-Fi communication experience. The Wi-Fi service performed during retransmission period T2 can be understood as receiving Wi-Fi data.

[0089] For example, as shown in Figure 4, when providing Wi-Fi services, a clear channel assessment (CCA) can be performed first to verify whether the channel for providing Wi-Fi services is clear. Wi-Fi services can be provided when the channel is clear, and can be temporarily suspended when the channel is not clear, in order to improve the quality of Wi-Fi services.

[0090] Figure 6 illustrates a schematic diagram of another short-range wireless communication system architecture according to an embodiment of this application. Referring to Figure 6, the implementation of this embodiment is basically similar to the relevant content in the embodiment described in Figure 3 above, except that the data transmission mechanism between the terminal device and multiple audio devices is different. For example, taking mobile phone 10 as the terminal device, TWS earphones as multiple audio devices, and Bluetooth connection as the short-range connection, the first antenna 12a in mobile phone 10 establishes Bluetooth connections with the first antenna 211a in the left earphone and the first antenna 221a in the right earphone, respectively. The second antenna 12b in mobile phone 10 establishes Bluetooth connections with the second antenna 211b in the left earphone and the second antenna 221b in the right earphone, respectively. The dashed lines in Figure 6 represent Bluetooth connections. Assuming that the first antenna 12a in mobile phone 10 uses frequency domain resource A when transmitting data, and the second antenna 12b uses frequency domain resource B when transmitting data, mobile phone 10 can simultaneously transmit the left channel data L to one of the earpieces (e.g., the left earpiece) using both frequency domain resources A and B. Then, mobile phone 10 can simultaneously transmit the right channel data R to the other earpiece (e.g., the right earpiece) using both frequency domain resources A and B. This allows mobile phone 10 to simultaneously transmit the same channel data to one earpiece using different frequency domain resources, and alternately transmit different channel data to the left and right earpieces. Referring to the timing diagram in Figure 7, simultaneously transmitting the same channel data using different frequency domain resources increases the transmission bandwidth of each channel, thereby shortening the communication time of each channel data (i.e., shortening the communication window), increasing the data throughput rate, further improving air interface transmission efficiency, and thus further improving data transmission rate and anti-interference capability.

[0091] Frequency domain resources A and B can be different frequency domain resources in the 2.4GHz band, 5GHz band, or 6GHz band, or other unlicensed frequency bands. For example, frequency domain resources A and B can be different frequency domain resources in the 2.4GHz band, etc., and will not be listed here. Alternatively, different frequency domain resources can include at least two of the 2.4GHz, 5GHz, and 6GHz bands. For example, frequency domain resource A can be in the 2.4GHz band, and frequency domain resource B can be in the 5GHz band; or frequency domain resource A can be in the 2.4GHz band, and frequency domain resource B can be in the 6GHz band; or frequency domain resource A can be in the 5GHz band, and frequency domain resource B can be in the 5GHz band, etc., and will not be listed here. The specific settings can be configured according to actual needs and are not specifically limited here.

[0092] Furthermore, this data transmission mechanism can be called the second data transmission mechanism. This second mechanism is applicable to the following scenarios: For example, taking the 2.4GHz band as an example, when multiple transmission channels are set within the 2.4GHz band, data from two audio channels can be transmitted separately through different transmission channels within the 2.4GHz band, increasing the transmission bandwidth of each channel and thus further improving air interface transmission efficiency. Alternatively, when one earphone is closer to the phone 10 and the other is farther away, the earphone that is farther away uses lower frequency domain resources in the 2.4GHz band to transmit audio data, while the earphone that is closer uses higher frequency domain resources in the 2.4GHz band. This can also reduce transmission loss to some extent and improve data transmission quality. Of course, the application scenarios of this second data transmission mechanism are not limited to the two listed above; other application scenarios are also possible. Specific applications can be made according to actual needs, and no specific limitations are made here.

[0093] In this embodiment, each earphone includes multiple antennas, such as the antenna in the left earphone indicated by 211a and 211b in Figure 6, and the antenna in the right earphone indicated by 221a and 221b in Figure 6. This allows for the reception of left and right channel data through different antennas, thereby enabling audio data transmission. The number of antennas included in any earphone is not limited to the two shown in Figure 6; it can be more than one. The specific number can be set according to actual needs and is not specifically limited here.

[0094] It should be understood that the similarities between this embodiment and the embodiment described in Figure 3 above can be found in the description of the above embodiments, and the repeated parts will not be repeated.

[0095] Figure 8 illustrates a schematic diagram of the architecture of another short-range wireless communication system according to an embodiment of this application. Referring to Figure 8, the implementation of this embodiment is basically similar to the relevant content in the embodiments described in Figures 3 to 5 above, except that: the short-range wireless communication system includes an audio device, and the terminal device simultaneously sends different data to the audio device through different frequency domain resources. For example, taking a mobile phone 10 as the terminal device, a speaker as the audio device, and Bluetooth connection as the short-range connection, when the mobile phone 10 sends audio data to the speaker, the following method can be used: the mobile phone 10 includes two antennas, one of which (i.e., the first antenna 12a) establishes a Bluetooth connection with the first antenna 231a inside the speaker, and the other antenna (i.e., the second antenna 12b) establishes a Bluetooth connection with the second antenna 231b inside the speaker, where the dashed line in Figure 7 represents the Bluetooth connection. Assuming that the first antenna 12a in mobile phone 10 uses frequency domain resource A when transmitting data, and the second antenna 12b uses frequency domain resource B, then mobile phone 10 can send one first data to the speaker through frequency domain resource A, and simultaneously send another first data to the same speaker through frequency domain resource B. This allows different first data to be transmitted simultaneously through different frequency domain resources, meaning mobile phone 10 sends different first data to the speaker at the same time, and the phone sends each first data in the configured order. Of course, all of these first data are Bluetooth data. This also reduces the duration of the audio transmission period within the communication cycle, increases the duration of the retransmission period, and improves the data transmission rate and anti-interference capability.

[0096] The number of antennas inside the speaker is not limited to two; it can also be three, four, or more. In this embodiment, the audio device is not limited to a speaker; it can also be a smart home device, a smart terminal, etc. The first data can be, but is not limited to, file data, image data, video data, or stereo data without channel splitting, as long as different data are simultaneously transmitted to the audio device through different frequency domain resources.

[0097] It should be understood that the configuration of frequency domain resource A and frequency domain resource B in this embodiment is basically similar to the embodiments described in Figures 3 to 5 above. For the similarities between this embodiment and the embodiments described in Figures 3 to 5 above, please refer to the descriptions in the aforementioned embodiments. Repeated parts will not be repeated.

[0098] Another short-range wireless communication system in this application embodiment is implemented in a manner basically similar to the embodiment described in Figure 8 above, except that the terminal device simultaneously sends the same data to the audio device through different frequency domain resources. For example, continuing to use a mobile phone as the terminal device, a speaker as the audio device, and Bluetooth as the short-range connection, the mobile phone 10 can simultaneously send one set of first data to the speaker through frequency domain resources A and B. Then, the mobile phone 10 simultaneously sends another set of first data to the speaker through frequency domain resources A and B. This allows the same first data to be sent simultaneously through different frequency domain resources at the same time, and the different first data are sent sequentially. This increases the transmission bandwidth of each set of first data, thereby shortening the communication time of each set of first data, i.e., shortening the communication window duration, increasing the data throughput rate, further improving the air interface transmission efficiency, and thus further improving the data transmission rate and anti-interference capability.

[0099] It should be understood that the configuration of frequency domain resource A and frequency domain resource B in this embodiment is basically similar to that in the embodiments described in Figures 6 and 7 above. For details, please refer to the description of the embodiments described in Figures 6 and 7 above. The similarities between this embodiment and the embodiment described in Figure 8 above can be found in the descriptions in the previous embodiments. Repeated parts will not be repeated.

[0100] Based on the above, this application embodiment also provides a terminal device. Referring to Figures 9 and 10, the terminal device may include: a processor 11 and multiple antennas. The multiple antennas may have the structure indicated by 12a, 12b, 12c, and 12d in Figures 9 and 10, where 12c represents a third antenna in a terminal device such as a mobile phone, and 12d represents a fourth antenna in a terminal device such as a mobile phone. The processor 11 is coupled to the multiple antennas. The antennas are used to: establish short-range connections with at least a portion of at least one audio device (not shown in Figures 9 and 10), and to send data to the connected audio devices. Each antenna corresponds to at least one frequency domain resource in short-range communication. The processor 11 is used to: in response to receiving a data transmission instruction, simultaneously send the same type of short-range communication data to at least one audio device through different frequency domain resources of different antennas. Thus, by sending the same type of short-range communication data to at least one audio device simultaneously through different frequency domain resources, the communication time between the terminal device and any audio device can be reduced. Compared with the prior art of sequentially sending the same type of short-range communication data through the same frequency domain resources, this effectively reduces the occupation of air interface resources, improves air interface transmission efficiency, increases retransmission opportunities, and thereby improves the data transmission rate and anti-interference capability.

[0101] To implement the first data transmission mechanism described above, the processor 11 can be specifically configured to: simultaneously transmit different channel data to at least one audio device using different frequency domain resources of different antennas. To implement the second data transmission mechanism described above, the processor 11 can be specifically configured to: simultaneously transmit the same channel data to at least one audio device using different frequency domain resources of different antennas, and sequentially transmit different channel data to any audio device. Thus, both the first and second data transmission mechanisms can be implemented with the cooperation of the processor 11 and multiple antennas, thereby improving anti-interference capabilities.

[0102] For example, the processor 11 may include a plurality of first short-range communication modules 111 and a plurality of first radio frequency front-end modules 112. The first short-range communication modules 111 are correspondingly configured and coupled to the first radio frequency front-end modules 112. The first radio frequency front-end modules 112 are also correspondingly configured and coupled to an antenna, such that each first short-range communication module 111 is used to couple to a corresponding antenna. In this way, the first short-range communication module 111 can send a radio frequency signal carrying audio data to the corresponding first radio frequency front-end module 112. The first radio frequency front-end module 112 filters, amplifies and processes the received radio frequency signal and then transmits it to the corresponding antenna. Finally, the processed radio frequency signal is transmitted out through the antenna.

[0103] Among them, different first short-range communication modules 111 correspond to different frequency domain resources, so that the radio frequency signals output by different first short-range communication modules 111 are simultaneously transmitted outward through the corresponding frequency domain resources. The different radio frequency signals transmitted at the same time carry the same type of short-range communication data, such as, but not limited to, the different radio frequency signals transmitted at the same time all carrying Bluetooth data or all carrying star flash data. Furthermore, when different first short-range communication modules 111 correspond to different frequency domain resources, the configuration of the first short-range communication module 111 and the antenna can include two methods: First, different first short-range communication modules 111 are coupled to different antennas, meaning different first short-range communication modules 111 correspond to different antennas. When the frequency domain resources of the antenna and the corresponding first short-range communication module 111 are the same, the frequency domain resources corresponding to different antennas are also different, and each antenna can correspond to one frequency domain resource. Second, some first short-range communication modules 111 are coupled to different antennas, meaning some first short-range communication modules 111 correspond to different antennas. In this case, some first short-range communication modules 111 correspond to the same antenna. If this part of the first short-range communication modules 111 corresponding to the same antenna is called a multiplexed antenna, then when the frequency domain resources of the antenna and the corresponding first short-range communication module 111 are the same, the multiplexed antenna can correspond to multiple frequency domain resources, while the non-multiplexed antenna can correspond to one frequency domain resource.

[0104] In the second configuration, the frequency domain resources corresponding to the multiple first short-range communication modules 111 coupled to the same antenna should be resources in different frequency bands. If a frequency domain resource is regarded as a transmission channel, then the transmission channels corresponding to the multiple first short-range communication modules 111 coupled to the same antenna should be transmission channels in different frequency bands; for example, but not limited to, there is a transmission channel a1 in the 5GHz band and a transmission channel a2 in the 6GHz band. The first short-range communication module 111 corresponding to transmission channel a1 and the first short-range communication module 111 corresponding to transmission channel a2 are both coupled to the same antenna. This can avoid different transmission channels in the same frequency band corresponding to the same antenna, thereby avoiding the inability to transmit two data simultaneously through the same antenna.

[0105] It should be noted that the first short-range communication module 111 in this embodiment has the same meaning as the short-range communication module in the invention, and the first radio frequency front-end module 112 has the same meaning as the radio frequency front-end module in the invention.

[0106] When the terminal device also has Wi-Fi functionality, the processor 11 may further include: multiple second short-range communication modules 113 and second radio frequency front-end modules 114. The second short-range communication modules 113 and second radio frequency front-end modules 114 are configured and coupled one-to-one. The second radio frequency front-end modules 114 are also configured and coupled one-to-one with antennas. The second radio frequency front-end modules 114 filter, amplify, and process the radio frequency signals carrying Wi-Fi data received through the antennas before transmitting them to the corresponding second short-range communication modules 113. The second short-range communication modules 113 can process the received radio frequency signals to obtain Wi-Fi data. Therefore, for the antenna, when the terminal device also has Wi-Fi functionality, the antenna can also be used to receive Wi-Fi data during retransmission periods. Furthermore, when the first short-range communication module 111 mentioned above can be a module for implementing Bluetooth communication or satellite communication, coexistence of Bluetooth communication (or satellite communication) and Wi-Fi communication can be achieved.

[0107] Taking the first short-range communication module 111 as a module for implementing Bluetooth communication, and different first short-range communication modules 111 being coupled to different antennas as an example, when the terminal device has both Bluetooth and Wi-Fi functions, the antenna configuration can include the following situations:

[0108] Scenario 1: Separate antenna design, meaning the first RF front-end module 112 and the second RF front-end module 114 are coupled to different antennas. For example, as shown in Figure 9, the figure shows two first RF front-end modules 112, two second RF front-end modules 114, and four antennas. The uppermost first RF front-end module 112 and the uppermost second RF front-end module 114 are coupled to different antennas (as indicated by structures 12a and 12c in Figure 9), while the lowermost first RF front-end module 112 and the lowermost second RF front-end module 114 are coupled to different antennas (as indicated by structures 12b and 12d in Figure 9). In this way, both the first RF front-end module 112 and the second RF front-end module 114 can transmit RF signals through their respective corresponding antennas, avoiding mutual interference between the RF signals processed by the first RF front-end module 112 and the second RF front-end module 114. This improves the transmission performance of Bluetooth and Wi-Fi RF signals and enhances the coexistence experience of Bluetooth and Wi-Fi.

[0109] Scenario 2: Shared antenna design but separate RF front-end modules, meaning the first RF front-end module 112 and the second RF front-end module 114 are coupled to the same antenna. For example, assuming there are two first RF front-end modules 112, two second RF front-end modules 114, and two antennas (not shown), one first RF front-end module 112 and one second RF front-end module 114 are each coupled to one antenna, and another first RF front-end module 112 and another second RF front-end module 114 are each coupled to the other antenna. This reduces the number of antennas, simplifies the structure of the terminal device, and thus reduces the manufacturing cost of the terminal device.

[0110] Case 3: Shared antenna design and shared RF front-end module design, that is, only the first RF front-end module 112 or only the second RF front-end module 114 is set. For example, when only the first RF front-end module 112 is set, the first short-range communication module 111 and the second short-range communication module 113 share the first RF front-end module 112; or, when only the second RF front-end module 114 is set, the first short-range communication module 111 and the second short-range communication module 113 share the second RF front-end module 114. Taking a setup with only the first RF front-end module 112 as an example, as shown in Figure 10, the figure illustrates two first short-range communication modules 111, two second short-range communication modules 113, two first RF front-end modules 112, and two antennas. The uppermost first short-range communication module 111 and the uppermost second short-range communication module 113 are coupled to the uppermost first RF front-end module 112, and the uppermost first RF front-end module 112 is coupled to the uppermost antenna (structure indicated by 12a in Figure 10). The lowermost first short-range communication module 111 and the lowermost second short-range communication module 113 are coupled to the lowermost first RF front-end module 112, and the lowermost first RF front-end module 112 is coupled to the lowermost antenna (structure indicated by 12a in Figure 10). This reduces the number of RF front-end modules while minimizing the number of antennas, further simplifying the terminal device's structure and thus reducing manufacturing costs, size, and weight.

[0111] In practical implementation, depending on the actual situation, the antenna and RF front-end module can be designed according to scenario 1, scenario 2 or scenario 3 above to meet the needs of different applications and expand the application scope.

[0112] For example, when the processor 11 includes only a first short-range communication module 111, each of the first short-range communication modules 111 can be integrated together to form a radio frequency (RF) chip, so that the RF chip can include multiple first short-range communication modules 111, and this structure can be applied to terminal devices with Bluetooth or Starlink connectivity; when the processor 11 includes a first short-range communication module 111 and a second short-range communication module 113, each of the first short-range communication modules 111 and each of the second short-range communication modules 113 can be integrated together to form an RF chip, so that the RF chip can include multiple first short-range communication modules 111 and multiple second short-range communication modules 113 to achieve an integrated design of the structure, and this structure can be applied to terminal devices with Bluetooth (or Starlink) connectivity and Wi-Fi functionality.

[0113] Furthermore, both the first short-range communication module 111 and the second short-range communication module 113 can include a baseband unit m1 and a radio frequency transceiver unit m2. The baseband unit m1 is coupled to the radio frequency transceiver unit m2, and the radio frequency transceiver unit m2 is used to couple to the corresponding antenna. That is, the radio frequency transceiver unit m2 is coupled to the corresponding antenna through the corresponding radio frequency front-end module. During signal transmission, the radio frequency transceiver unit m2 can modulate the mid-to-high frequency digital signal carrying audio data from the baseband unit m1 into a high-frequency electromagnetic wave signal (i.e., a radio frequency signal), and transmit the radio frequency signal to the corresponding radio frequency front-end module. The radio frequency front-end module can perform power amplification, filtering, and other processing on the radio frequency signal, and then radiate the amplified and filtered radio frequency signal through the antenna. During signal reception, the RF front-end module can perform filtering and low-noise amplification on the RF signal received by the antenna. The RF transceiver unit m2 can demodulate the filtered and low-noise amplified RF signal into a medium-to-high frequency digital signal and send the medium-to-high frequency digital signal to the baseband unit m1. This allows the information carried in the RF signal received by the antenna to be extracted, thereby enabling short-range communication.
