[0001] This application claims priority to Chinese Patent Application No. 202411997192.8, filed with the State Intellectual Property Office of China on December 31, 2024, entitled "Radio Frequency System, Terminal Equipment and Communication Method Thereof", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of communication technology, and in particular to a radio frequency system, terminal equipment and communication method thereof. Background Technology

[0003] With the development of human society, mobile phones and other terminal devices have become indispensable tools in people's lives. People's dependence on terminal devices has affected all aspects of their lives. With the rapid development of communication technology and the popularization of smart terminals, people have increasingly higher requirements for terminal devices, especially for their communication capabilities.

[0004] Antenna systems are a crucial component for communication in terminal devices, and their communication efficiency is a key factor affecting the communication capabilities of these devices. Currently, terminal devices utilize techniques such as time-division multiplexing of antennas to ensure that various service scenarios do not conflict, thus guaranteeing communication performance to a certain extent. However, the communication performance of terminal devices still needs further improvement. Summary of the Invention

[0005] This application provides a radio frequency system, a terminal device, and a communication method thereof to improve the communication performance of the terminal device.

[0006] A first aspect of this application provides a radio frequency system for controlling performance assistance between a first radiator and a second radiator in a terminal device.

[0007] The radio frequency (RF) system includes: an RF signal generation circuit, a control node, a first tuning circuit, and a second tuning circuit. The first tuning circuit includes a first input terminal, a first output terminal, and a first control terminal; the first output terminal is used for coupling with a first radiator. The second tuning circuit includes a second input terminal, a second output terminal, and a second control terminal; the second output terminal is used for coupling with a second radiator. The control node is coupled to both the first control terminal and the second control terminal. The RF signal generation circuit is coupled to the first input terminal, the second input terminal, and the control node.

[0008] The radio frequency (RF) signal generation circuit, based on first and second communication standard service information, controls the first tuning circuit to a first state and the second tuning circuit to a second state via a control node. In the first state, the first tuning circuit processes the RF signal of the first communication standard, and in the second state, the second tuning circuit processes the RF signal of the first communication standard. In this configuration, the first communication standard takes precedence, and the control node can control the second tuning circuit to assist the first tuning circuit in processing the RF signal of the first communication standard, thereby achieving assistance from the second radiator to the first radiator and improving the performance of the RF signal of the first communication standard.

[0009] The radio frequency (RF) signal generation circuit is also used to control the first tuning circuit to a first state and the second tuning circuit to a third state via a control node, based on the first and second communication standard service information. In the first state, the first tuning circuit processes RF signals of the first communication standard, while in the third state, the second tuning circuit processes RF signals of the second communication standard. In this configuration, the first and second communication standards coexist, and the control node can prevent the first and second tuning circuits from cooperating, thus achieving non-cooperation between the first and second radiators. Alternatively, the control node can finely control the first and second tuning circuits based on the ratio of the data transmission rates of the first and second communication standards, thereby achieving mutual assistance between the first and second radiators, i.e., mutual performance enhancement.

[0010] In the radio frequency system provided in this application embodiment, both the first tuning circuit and the second tuning circuit are coupled to a control node and synchronously controlled by the control node. In the radio frequency system, the radio frequency signal generation circuit controls the state of the first and second tuning circuits based on first and second communication standard service information. Based on different service information, the radio frequency signal generation circuit generates different assistance instructions. For example, based on the first and second communication standard service information, the first communication standard is prioritized, and the control node controls both the first and second tuning circuits to process the first communication standard radio frequency signal. The second tuning circuit and the second radiator coupled to the second tuning circuit assist the first tuning circuit and the first radiator coupled to the first tuning circuit in processing the first communication standard radio frequency signal, which helps improve the communication performance of the first communication standard, thereby improving the communication performance of the terminal device. Alternatively, for example, based on the first and second communication standard service information, the coexistence of the first and second communication standards is determined, and the control node controls the first tuning circuit to process the first communication standard radio frequency signal and controls the second tuning circuit to process the second communication standard radio frequency signal. However, at this point, the control node has already controlled the second tuning circuit to reduce the radiation performance of the second communication standard (or understand it as the proportion of current intensity), and controlled the first tuning circuit to increase the radiation performance of the first communication standard (or vice versa). Although the second tuning circuit does not assist in processing the radio frequency signal of the first communication standard, it can still improve the performance of the first communication standard, thereby improving the communication performance of the terminal device.

[0011] In one possible implementation, the radio frequency (RF) signal generation circuit is further configured to, based on the first and second communication standard service information, control the first tuning circuit to a fourth state and the second tuning circuit to a third state via a control node. In the fourth state, the first tuning circuit processes the second communication standard RF signal, and in the third state, the second tuning circuit processes the second communication standard RF signal. In this case, the second communication standard takes precedence, and the control node can control the first tuning circuit to assist the second tuning circuit in processing the second communication standard RF signal, thereby improving the performance of the second communication standard RF signal. Then, in the terminal device, the RF system can control the second radiator to assist the first radiator, and vice versa. This improves the communication performance of both the first and second communication standards.

[0012] In one possible implementation, the radio frequency (RF) signal generation circuit includes a modem and an RF chip; the RF chip is coupled to both the modem and the control node; the modem receives service information for a first communication standard and service information for a second communication standard, and the RF chip outputs a first control signal and a second control signal to the control node. The first control signal controls a first tuning circuit to be in a first state and a second tuning circuit to be in a second state, and the second control signal controls the first tuning circuit to be in the first state and the second tuning circuit to be in a third state. Both communication standard links require a modem and an RF chip, and these two components can be integrated into a single structure to simplify the RF system architecture and improve its integration.

[0013] In one possible implementation, the RF chip is also used to output a third control signal to the control node. This third control signal controls the first tuning circuit to be in a fourth state and the second tuning circuit to be in a third state. In the integrated architecture, the RF system can control the second radiator to assist the first radiator, and vice versa.

[0014] In one possible implementation, the RF signal generation circuit further includes an RF front-end module; the RF front-end module is coupled to the RF chip, the first tuning circuit, and the second tuning circuit, respectively. Both communication standards require an RF front-end module, and the RF front-end modules required for both communication standards can be integrated into a single structure to simplify the architecture of the RF system and improve its integration.

[0015] In one possible implementation, the radio frequency (RF) signal generation circuit includes a first sub-modem, a second sub-modem, and an RF chip; the first and second sub-modems are coupled; the first and second sub-modems are respectively coupled to the RF chip, and the RF chip is coupled to a control node. The first sub-modem is used to receive service information of a first communication standard, and the second sub-modem is used to receive service information of a second communication standard; the RF chip is used to control the state of the first and second tuning circuits through the control node. The first sub-modem is located on the first communication standard link, and the second sub-modem is located on the second communication standard link. The coupling between the first and second sub-modems allows for real-time communication of their service information, improving the matching of the RF chip's control over the state of the first and second tuning circuits.

[0016] In one possible implementation, the RF chip includes a first communication standard RF chip and a second communication standard RF chip; the first communication standard RF chip is coupled to a control node; the first communication standard RF chip is also coupled to a first sub-modem, and the second communication standard RF chip is coupled to a second sub-modem; or, the first communication standard RF chip is coupled to the first sub-modem, the second communication standard RF chip is coupled to the second sub-modem, and the second communication standard RF chip is coupled to the first communication standard RF chip. The first communication standard RF chip is coupled to the control node, and control signals are always output to the control node through the first communication standard RF chip. The second communication standard link also utilizes the control path between the first communication standard RF chip and the control node, simplifying the architecture of the RF system.

[0017] In one possible implementation, the radio frequency (RF) chip includes a first communication standard RF chip and a second communication standard RF chip. The first communication standard RF chip is coupled to a first sub-modem, and the second communication standard RF chip is coupled to a second sub-modem. The first and second communication standard RF chips are also coupled to a control node. The first communication standard RF chip outputs a first control signal and a second control signal to the control node, and the second communication standard RF chip outputs a third control signal to the control node. When the first communication standard RF chip outputs the first or second control signal, the second communication standard RF chip stops outputting the third control signal; when the second communication standard RF chip outputs the third control signal, the first communication standard RF chip stops outputting the first and second control signals. That is, the first and second communication standard RF chips each have the ability to output control signals to the control node, enabling the first sub-modem and the first communication standard RF chip to directly enter sleep mode when the first sub-modem is not working. Similarly, when the second sub-modem is not working, the second sub-modem and the second communication standard RF chip can directly enter sleep mode to save power.

[0018] In one possible implementation, the RF signal generation circuit further includes an arbitration circuit. The arbitration circuit is coupled to both the modem and the control node, and is used to receive service information for the first and second communication standards, and to send a third control signal to the control node. When the RF chip outputs either the first or second control signal, the arbitration circuit stops outputting the third control signal; conversely, when the arbitration circuit outputs the third control signal, the RF chip stops outputting both the first and second control signals. The arbitration circuit is always active. On one hand, it handles service decision-making on the second communication standard link, determining whether to output the third control signal and managing conflicts through assistance or mutual support. On the other hand, it temporarily stores the service information for both the first and second communication standards, managing both service and status information uniformly. When the modem is not in operation, the relevant functional modules can hibernate to save power, and uniformly send the service information to the arbitration circuit for storage.

[0019] In one possible implementation, the modem includes a first sub-modem and a second sub-modem, coupled together. An arbitration circuit is coupled to both the first and second sub-modems. The arbitration circuit stores service information of the first and second sub-modems. After the first sub-modem starts up, it can directly retrieve the previously stored service information of the second sub-modem from the arbitration circuit, without waiting for the second sub-modem to transmit service information. This allows for faster decision-making for assistance or mutual aid, improving communication efficiency. Similarly, the arbitration circuit stores the service information of the first and second sub-modems. After the second sub-modem starts up, it can directly retrieve the previously stored service information of the first sub-modem from the arbitration circuit, without waiting for the first sub-modem to transmit service information. This also allows for faster decision-making for assistance or mutual aid, improving communication efficiency. Furthermore, the arbitration circuit already stores the latest service information of the first and second sub-modems. When either the first or second sub-modem wants to go into sleep mode, it can completely enter sleep mode, saving power.

[0020] In one possible implementation, the radio frequency (RF) chip includes a first communication standard RF chip and a second communication standard RF chip. The first communication standard RF chip is coupled to a first sub-modem, and the second communication standard RF chip is coupled to a second sub-modem. The RF signal generation circuit also includes a switching switch; a first terminal of the switching switch is coupled to both the first and second communication standard RF chips, a second terminal of the switching switch is coupled to a control node, and a third control terminal of the switching switch is coupled to the first communication standard RF chip. The switching switch is used to, under the control of the third control terminal, either open the path between the first communication standard RF chip and the control node, or open the path between the second communication standard RF chip and the control node. By using the switching switch, only one of the paths between the first and second communication standard RF chips can be opened, achieving mutual exclusion between the control of the first and second communication standard links. This is beneficial for improving the communication stability of the first and second communication standard links, thereby improving the communication performance of the terminal device.

[0021] In one possible implementation, the radio frequency signal generation circuit also includes a processor; the processor is coupled to the modem and is used to output scenario decision information to the modem. The processor can make scenario decision information based on the usage scenario. The scenario arbitration and the modem's real-time service arbitration are used in combination to make accurate and mutually supportive decisions on communication standard service information in real time, resulting in better communication performance.

[0022] In one possible implementation, the radio frequency (RF) chip includes a first communication standard RF chip and a second communication standard RF chip. The first communication standard RF chip is coupled to a first sub-modem, and the second communication standard RF chip is coupled to a second sub-modem. For example, the first communication standard RF chip is used to receive first communication standard service information and second communication standard service information, and controls the first tuning circuit to be in a first state and the second tuning circuit to be in a second or third state via a control node. The RF signal generation circuit also includes an arbitration circuit and a switching switch; the arbitration circuit is coupled to the modem and the control node respectively, and is used to receive the first communication standard service information and the second communication standard service information, and controls the states of the first and second tuning circuits via the control node. For example, the control node controls the first tuning circuit to be in a fourth state and controls the second tuning circuit to be in a third state. The first terminal of the switch is coupled to both the first communication standard RF chip and the arbitration circuit. The second terminal of the switch is coupled to the control node, and the third control terminal of the switch is coupled to the first communication standard RF chip. Under the control of the third control terminal, the switch can either open the path between the first communication standard RF chip and the control node, or open the path between the arbitration circuit and the control node. By switching the switch, only one of the paths between the first communication standard RF chip and the control node, or between the arbitration circuit and the control node, can be opened. This achieves mutual exclusion between the control of the first communication standard link and the control of the second communication standard link, which helps improve the communication stability of the first and second communication standard links, thereby enhancing the communication performance of the terminal device.

[0023] In one possible implementation, the radio frequency signal generation circuit further includes a processor; the processor is coupled to both the modem and the arbitration circuit, and is used to output scenario decision information to the modem and the arbitration circuit. The processor can make scenario decision information based on the usage scenario. The combination of scenario arbitration and the modem's real-time service arbitration enables accurate assistance or mutual aid decisions regarding communication standard service information in real time, resulting in superior communication performance.

[0024] In one possible implementation, the radio frequency signal generation circuit further includes an arbitration circuit. The arbitration circuit is coupled to a modem and is used to receive service information for both the first and second communication standards. The second communication standard radio frequency chip is coupled to a control node, and the arbitration circuit sends a third control signal to the second communication standard radio frequency chip via the modem. In this case, the arbitration circuit undertakes the task of service decision-making in the second communication link, and the generated third control signal is transmitted to the second communication standard radio frequency chip via the modem. Furthermore, the arbitration circuit stores the service information for the first communication standard, which can be directly retrieved during service arbitration without waiting for the first communication standard service information to be transmitted, allowing for faster decision-making for assistance or mutual support and improving communication efficiency.

[0025] In one possible implementation, after the first sub-modem sends a switching signal to the second sub-modem, the first communication standard RF chip controls a switching switch to open the path between the first communication standard RF chip and the control node, and controls the switching switch to close the path between the second communication standard RF chip and the control node. That is, the first communication standard RF chip preempts control of the first and second tuning circuits. By giving the first communication standard link the preemptive right of the switching switch, it is possible to promptly seize control of the first and second tuning circuits from the second communication standard RF chip when an emergency communication demand arises in the first communication standard link, allowing the terminal device to quickly enter the first communication standard communication scenario.

[0026] In one possible implementation, after the modem sends a switching signal to the arbitration circuit, the first communication standard RF chip controls the switching switch to open the path between the first communication standard RF chip and the control node, and also controls the switching switch to close the path between the arbitration circuit and the control node. That is, the first communication standard RF chip preempts control of the first and second tuning circuits. By giving the first communication standard link the preemptive right of the switching switch, it is possible to promptly seize control of the first and second tuning circuits from the arbitration circuit when an emergency communication demand arises in the first communication standard link, allowing the terminal device to quickly enter the first communication standard communication scenario.

[0027] In one possible implementation, the first sub-modem and the second sub-modem are coupled via a communication path. The first sub-modem sends first communication standard service information to the second sub-modem via the communication path, and the second sub-modem sends second communication standard service information to the first sub-modem via the same communication path. For example, the first and second sub-modems can be coupled via a UART interface, a PCIe interface, an I3C communication interface, and an IPC interface. The first and second sub-modems can transmit a large amount of service information through the communication path, meeting the real-time service synchronization requirements of the first and second sub-modems.

[0028] In one possible implementation, a first signal path is coupled between the first sub-modem and the second sub-modem, through which the first sub-modem sends its operating status information to the second sub-modem. The first and second sub-modems can transmit operating status information via GPIO, and the operating status information can be characterized by high / low levels, rising edges, or falling edges. Therefore, transmitting via the first signal path simplifies the architecture of the RF system.

[0029] In one possible implementation, a second signal path is coupled between the first and second sub-modems; the first and second sub-modems transmit timing synchronization information through this second signal path. The first and second sub-modems have their own timing sequences; if they are not synchronized, timing discrepancies will occur. By establishing a second signal path between the first and second sub-modems to transmit timing synchronization information, the risk of timing discrepancies can be reduced.

[0030] In one possible implementation, the RF chip is coupled to the control node via a clock path and a data path. The RF chip controls the control node to control the states of the first and second tuning circuits through the clock and data paths. For example, the RF chip transmits a first control signal and a second control signal to the control node through the clock and data paths. Alternatively, the RF chip can be coupled to the control node via MIPI, with the clock path transmitting a clock signal and the data path transmitting a data signal. The clock and data signals can be combined to generate various control signals to synchronously control multiple tuning circuits, simplifying the architecture of the RF system.

[0031] In one possible implementation, the radio frequency system includes a system-on-a-chip (SoC); the arbitration circuit is housed within the SoC; and the SoC is coupled to the control node via clock and data paths. For example, the SoC includes a MIPI (Multi-Installation Interface), the arbitration circuit is coupled to the SoC's MIPI, and the SoC's MIPI is used to couple with the first and second child nodes. This approach improves the integration of the communication system and simplifies the arbitration circuit structure by utilizing the SoC's MIPI.

[0032] In one possible implementation, the first communication standard radio frequency signal is a cellular radio frequency signal, and the second communication standard radio frequency signal is a non-cellular radio frequency signal. This application enables cooperation or mutual assistance between cellular and non-cellular systems.

This application enables cooperation or mutual assistance between cellular and satellite systems.

[0034] In one possible implementation, the first communication standard radio frequency signal is a non-cellular radio frequency signal, and the second communication standard radio frequency signal is a satellite radio frequency signal. This application enables cooperation or mutual assistance between non-cellular and satellite systems.

[0035] In one possible implementation, the first communication standard radio frequency signal is a cellular radio frequency signal, and the second communication standard radio frequency signal is a cellular radio frequency signal. This application enables cooperation or mutual assistance between cellular cells.

[0036] In one possible implementation, both the first communication standard radio frequency signal and the second communication standard radio frequency signal are non-cellular radio frequency signals. This application enables cooperation or mutual assistance between non-cellular and non-cellular systems.

[0037] In one possible implementation, both the first and second communication standard radio frequency signals are satellite radio frequency signals. This application enables cooperation or mutual assistance between satellites.

[0038] In one possible implementation, the radio frequency system further includes a third tuning circuit. This third tuning circuit includes a third input terminal, a third output terminal, and a fourth control terminal. The third input terminal is coupled to the radio frequency signal generation circuit, the third output terminal is used for coupling with a third radiator, and the fourth control terminal is coupled to a control node. The radio frequency signal generation circuit is also used to receive service information of a third communication standard, output a fourth control signal to the control node, control the first tuning circuit to be in a first state, control the second tuning circuit to be in a second state, and control the third tuning circuit to be in a fifth state. In the first state, the first tuning circuit processes the radio frequency signal of the first communication standard; in the second state, the second tuning circuit processes the radio frequency signal of the first communication standard; and in the fifth state, the third tuning circuit processes the radio frequency signal of the first communication standard. In this case, the first communication standard takes priority. The fourth control signal can control the second and third tuning circuits to assist the first tuning circuit in processing the radio frequency signal of the first communication standard, thereby achieving assistance or mutual support between the second and third radiators for the first radiator and improving the performance of the radio frequency signal of the first communication standard. For example, the first communication standard is satellite, and the second and third communication standards are cellular and non-cellular, respectively.

[0039] Based on the service information of the first communication standard, the service information of the second communication standard, and the service signal of the third communication standard, the priority of the first communication standard is determined, and a corresponding fourth control signal is generated. The fourth control signal controls the first, second, and third tuning circuits to process the radio frequency signal of the first communication standard. The second tuning circuit and the second radiator for coupling with the second tuning circuit, and the third tuning circuit and the third radiator for coupling with the third tuning circuit, together assist the first tuning circuit and the first radiator for coupling with the first tuning circuit in processing the radio frequency signal of the first communication standard, which helps to improve the communication performance of the first communication standard, thereby improving the communication performance of the terminal device.

By determining the ratio of data transmission rates for the first and second communication standards, the current allocation ratio between the first and second communication standard links is established, enabling assistance or mutual support between them. Although the first and second communication standard links are processing their own radio frequency signals, changes in radiation performance can still achieve assistance or mutual support, thereby improving the communication performance of the terminal device.

[0083] The technical solutions of the embodiments of this application will be described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0084] Hereinafter, the terms "second," "first," etc., are used for descriptive convenience only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "second," "first," etc., may explicitly or implicitly include one or more of that feature. In the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0085] The term "coupling" should be interpreted broadly. For example, "coupling" can refer to a direct electrical connection, such as physical contact and electrical conduction between two components. It can also be understood as the electrical connection between different components in a circuit structure through physical lines that can transmit electrical signals, such as copper foil or wires on a printed circuit board (PCB), to transmit electrical signals. Alternatively, "coupling" can refer to an indirect electrical connection between two components through an intermediate medium. Or, "coupling" can refer to an electrical connection between two components in a non-contact manner, such as a capacitive coupling between two components to transmit electrical signals.

[0086] In this embodiment of the application, "and / or" describes the relationship between associated objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone, where A and B can be singular or plural. The character " / " generally indicates that the preceding and following associated objects have an "or" relationship.

[0087] Radiator: In an antenna, this is the device used to receive / transmit electromagnetic wave radiation. In some cases, the term "antenna" is narrowly defined as a radiator, which converts guided wave energy from the transmitter into radio waves, or converts radio waves into guided wave energy, for radiating and receiving radio waves. The modulated high-frequency current energy (or guided wave energy) generated by the transmitter is transmitted to the transmitting radiator via a feed line, where it is converted into electromagnetic wave energy of a specific polarization and radiated in the desired direction. The receiving radiator converts the electromagnetic wave energy of a specific polarization from a specific direction in space back into modulated high-frequency current energy, which is then transmitted to the receiver input via a feed line.

[0088] A tuner is a device used to adjust the input impedance of an antenna to match the output impedance of a radio transmitter and to adjust the antenna frequency. It adjusts the antenna's input impedance and frequency by changing the values ​​of inductors and capacitors to maximize the transmission of radio signals. Tuning circuits are commonly used in radio communications, broadcasting, and radar.

[0089] A radio frequency integrated circuit (RFIC) chip is a combination of all components of an antenna used for receiving and transmitting radio frequency waves. In the case of a receiving antenna, the RFIC can be considered the antenna section from the first amplifier to the front-end transmitter. In a transmitting antenna, the RFIC can be seen as the section after the last power amplifier. In some cases, the RFIC can also be understood as a feed unit. The RFIC has the function of converting radio waves into electrical signals and sending them to the receiver components. Generally, it is considered part of the antenna system for converting radio waves into electrical signals and vice versa. Antenna design should consider the maximum power transfer possibility and efficiency. For this purpose, the antenna feed impedance must be matched with the load resistance. The antenna feed impedance is a combination of resistance, capacitance, and inductance. To ensure maximum power transfer conditions, the two impedances (load resistance and feed impedance) should be matched. Matching can be achieved by considering frequency requirements and antenna design parameters such as gain, directivity, and radiation efficiency.

[0090] Modem (modulation and demodulation): Includes modules for baseband processing and modulation / demodulation.

[0091] Antenna radiation pattern: Also known as radiation pattern. It refers to the graphical representation of the relative field strength (normalized modulus) of the antenna's radiated field as a function of direction at a certain distance from the antenna. It is usually represented by two mutually perpendicular planar radiation patterns passing through the antenna's maximum radiation direction. Antenna radiation patterns typically have multiple radiating beams. The beam with the highest radiating intensity is called the main lobe, and the remaining beams are called side lobes. Among the side lobes, the side lobe in the opposite direction to the main lobe is also called the back lobe.

[0092] Radiation efficiency refers to the ratio of the power radiated by an antenna into space (i.e., the power effectively converted into electromagnetic waves) to the active power input to the antenna. The active power input to the antenna equals the antenna's input power minus the power loss. Power loss mainly includes return loss power, ohmic loss power of the metal, and / or dielectric loss power. Both metal loss and dielectric loss are factors affecting radiation efficiency.

[0093] Those skilled in the art will understand that radiation efficiency is generally expressed as a percentage, and there is a corresponding conversion relationship between it and dB. The closer the radiation efficiency is to 0 dB, the better the radiation efficiency of the antenna.

[0094] dB: This stands for decibel, a logarithmic concept with base 10. Decibels are used to evaluate the proportional relationship between two physical quantities; they themselves have no physical dimensions. For every 10-fold increase in the ratio between two quantities, their difference can be expressed as 10 decibels. For example: A = 100, B = 10, C = 5, D = 1, then A / D = 20 dB; B / D = 10 dB; C / D = 7 dB; B / C = 3 dB. In other words, a 10-decibel difference between two quantities is a 10-fold difference, a 20-decibel difference is a 100-fold difference, and so on. A 3-decibel difference is a 2-fold difference between the two quantities.

[0095] Figure 1 is a schematic diagram of a communication scenario of a terminal device provided in an embodiment of this application.

[0096] This application provides a terminal device that can provide users with wireless communication functions based on different protocol types. As shown in Figure 1, depending on the protocol type, the terminal device can perform cellular communication with a base station, satellite communication with a communication satellite, or non-cellular communication with short-range structures such as routers and headphones, to meet the usage needs in different scenarios.

[0097] Cellular communication falls under terrestrial communication and includes technologies such as 2G, 3G, 4G, 5G, and 5.5G. Non-cellular communication also falls under terrestrial communication and includes technologies such as Wireless Fidelity (WiFi), Bluetooth (BT), Bluetooth Low Energy (BLE), Near Link, SparkLink Low Energy (SLE), Location Based Services (LBS), Global Positioning System (GPS), Near-Field Communication (NFC), and Radio Frequency Identification (RFID). Satellite communication falls under non-terrestrial network (NTN) communication and includes geostationary orbit (GEO) satellite communication (also known as synchronous orbit communication satellites), medium Earth orbit (MEO) satellite communication, and low Earth orbit (LEO) satellite communication.

[0098] The terminal device in this application embodiment can be a mobile phone, tablet computer, laptop computer, smart home device, smart bracelet, smartwatch, smart helmet, virtual reality (VR) terminal device, augmented reality (AR) terminal device, positioning device, etc. The terminal device can also be a handheld device with wireless communication capabilities, a computing device or other processing device connected to a wireless modem, an in-vehicle device, a terminal device in a 5G network, or a terminal device in a future evolved public land mobile network (PLMN), etc.

[0099] Figure 2 illustrates a terminal device provided in an embodiment of this application, using a mobile phone as an example. The terminal device can be a common device such as a candybar phone or a foldable phone.

[0100] Figure 2 is a schematic diagram of the structure of a terminal device provided in an embodiment of this application.

[0101] This application provides a terminal device, as shown in FIG2. The terminal device includes a cover 100, a display / module 200, a printed circuit board (PCB) 300, a middle frame 400, and a rear cover 500. In one embodiment, the cover 100, the middle frame 400, and the rear cover 500 can all be considered as a housing.

[0102] In some embodiments, the cover plate 100 can be a glass cover plate, or it can be replaced with a cover plate made of other materials, such as an ultra-thin glass cover plate, a polyethylene terephthalate (PET) cover plate, etc. The cover plate 100 can be disposed in close contact with the display screen 200, and can be mainly used to protect the display screen 200 from dust.

[0103] In one embodiment, the display screen 200 may include a liquid crystal display (LCD), a light emitting diode (LED) display panel, or an organic light-emitting diode (OLED) display panel, etc., and this application does not limit it.

[0104] The mid-frame 400 primarily serves to support the entire device. Figure 2 shows the PCB 300 positioned between the mid-frame 400 and the back cover 500. It should be understood that in one embodiment, the PCB 300 may also be positioned between the mid-frame 400 and the display screen 200; this application does not impose any limitations on this. The PCB 300 can be made of flame-retardant material (FR-4), Rogers substrate, or a hybrid substrate of Rogers and FR-4, etc. Here, FR-4 is a designation for a flame-retardant material grade, and Rogers substrate is a high-frequency board. Electronic components, such as radio frequency chips, are mounted on the PCB 300.

[0105] In one embodiment, a metal layer may be disposed on the PCB 300. This metal layer can be used for grounding electronic components carried on the PCB 300, or for grounding other components such as bracket antennas, frame antennas, etc. This metal layer may be referred to as a ground plane, grounding plate, or grounding layer. In one embodiment, this metal layer can be formed by etching metal onto the surface of any dielectric substrate in the PCB 300. In one embodiment, the grounding metal layer may be disposed on the side of the PCB 300 near the middle frame 400. In one embodiment, the edge of the printed circuit board PCB 300 can be considered as the edge of its grounding layer. In one embodiment, the metal middle frame 400 can also be used for grounding the aforementioned components. The terminal device may also have other ground planes / grounding plates, as previously described, which will not be repeated here.

[0106] The terminal device may also include a battery (not shown in Figure 2). The battery may be located between the middle frame 400 and the back cover 500, or between the middle frame 400 and the display screen 200; this application does not impose any limitations on this. In some embodiments, the PCB 300 is divided into a motherboard and a daughterboard, and the battery may be located between the motherboard and the daughterboard. Specifically, the motherboard may be located between the middle frame 400 and the upper edge of the battery, and the daughterboard may be located between the middle frame 400 and the lower edge of the battery.

[0107] The terminal device may also include a bezel 600, which may be formed of a conductive material such as metal. The bezel 600 may be disposed between the display screen 200 and the back cover 500 and extend circumferentially around the periphery of the terminal device. The bezel 600 may have four sides surrounding the display screen 200 to help secure the display screen 200. In one implementation, the bezel 600 made of metal can be directly used as the metal bezel of the terminal device, forming a metal bezel appearance, suitable for industrial design (ID). In another implementation, the outer surface of the bezel 600 may also be made of a non-metallic material, such as a plastic bezel, forming a non-metallic bezel appearance, suitable for non-metallic ID.

[0108] The mid-frame 400 may include a border 600. The mid-frame 400, including the border 600, is a single unit that supports the electronic components within the device. The cover plate 100 and the rear cover 500 respectively cover the upper and lower edges of the border 600 to form the housing of the terminal device. Alternatively, the border 600 may not be considered part of the mid-frame 400. In one embodiment, the border 600 may be connected to the mid-frame 400 and integrally formed. In another embodiment, the border 600 may include inwardly extending protrusions to connect with the mid-frame 400, for example, via spring clips, screws, welding, etc. In one embodiment, the cover plate 100, the rear cover 500, the border 600, and the mid-frame 400 may be collectively referred to as the housing of the terminal device. It should be understood that "outer shell or housing" can be used to refer to part or all of any one of the cover plate 100, rear cover 500, frame 600 or middle frame 400, or to part or all of any combination of the cover plate 100, rear cover 500, frame 600 or middle frame 400.

[0109] The back cover 500 can be made of metal; it can also be made of non-conductive materials, such as glass or plastic; or it can be made of both conductive and non-conductive materials.

[0110] In one embodiment, the frame 600 can at least partially function as a radiator to transmit / receive radio frequency signals. This portion of the frame acting as the radiator may have gaps between itself and other parts of the middle frame 400, or between itself and the middle frame 400, thereby ensuring a good radiation environment for the radiator. In one embodiment, an aperture may be provided near this portion of the frame acting as the radiator. In one embodiment, the aperture may include an aperture disposed inside the terminal device, for example, an aperture not visible from the exterior of the terminal device. In one embodiment, the internal aperture may be formed by any one or multiple of the middle frame 400, battery, PCB 300, back cover 500, display screen 200, and other internal conductive components; for example, the internal aperture may be formed by a structural component of the middle frame 400. In one embodiment, the aperture may also include a gap / slit / opening on the frame 600. In one embodiment, the gap / slit / opening on the frame 600 may be a slit formed on the frame 600, at which the frame 600 is divided into two parts without a direct connection. In one embodiment, the aperture may further include a slit / gap / aperture provided on the back cover 500 or the display screen 200. In one embodiment, the back cover 500 includes a conductive material, and the aperture provided in the conductive material may communicate with a slit or gap in the frame to form a continuous aperture on the surface of the terminal device.

[0111] In one embodiment, the radiator of the terminal device may also be disposed within the frame 600. The frame 600 comprises a non-conductive material, and the radiator of the antenna may be located within the terminal device and disposed along the frame 600, or the radiator may be at least partially embedded within the non-conductive material of the frame. In one embodiment, the radiator is disposed close to the non-conductive material of the frame 600 to minimize the volume occupied by the radiator and to be closer to the outside of the terminal device, thereby achieving better signal transmission performance. It should be noted that "disposed close to the frame 600" means that the radiator can be disposed tightly against the frame 600 or close to the frame 600, for example, there may be a small gap between the radiator and the frame 600.

[0112] In one embodiment, the radiator of the terminal device may also be disposed within the housing, such as a bracket antenna disposed on a circuit board (not shown in Figure 2). A gap may exist between the radiator disposed within the housing and other conductive components inside the housing, thereby ensuring a good radiation environment for the radiator. In one embodiment, an aperture may be disposed near the radiator. In one embodiment, the aperture may include an aperture disposed inside the terminal device, for example, an aperture not visible from the exterior of the terminal device. In one embodiment, the internal aperture may be formed by any one or multiple of the frame 600, mid-frame 400, battery, PCB 300, back cover 500, display screen 200, and other internal conductive components; for example, the internal aperture may be formed by a structural component of the mid-frame 400. In one embodiment, the aperture may also include a slot / slit / opening on the frame 600. In one embodiment, the slot / slit / opening on the frame 600 may be a slit formed on the frame, at which the frame 600 is divided into two parts without a direct connection. In one embodiment, the aperture may also include a slot / slit / opening on the back cover 500 or the display screen 200. In one embodiment, the back cover 500 includes a conductive material, and the apertures formed in the conductive material can communicate with the slots or breaks in the frame to form continuous apertures on the surface of the terminal device. In one embodiment, the apertures on the back cover 500 or the display screen can also be used to house other devices, such as cameras, and / or sensors, and / or microphones, and / or speakers, etc.

[0113] In one embodiment, the antenna can be based on a flexible printed circuit (FPC), a laser-direct-structuring (LDS) antenna, or a microstrip disk antenna (MDA), among other forms. In another embodiment, the antenna can be a transparent or semi-transparent structure embedded within the screen of the terminal device, making it a transparent antenna element embedded within the screen of the terminal device.

[0114] Figure 2 only schematically shows some of the components included in the terminal device; the actual shape, size, and construction of these components are not limited by Figure 2.

[0115] It should be understood that in the embodiments of this application, the surface where the display screen of the terminal device is located can be considered as the front, the surface where the back cover is located as the back, and the surface where the frame is located as the side.

[0116] It should be understood that, in the embodiments of this application, when a user holds (typically vertically and facing the screen) a terminal device, the terminal device is considered to have a top, bottom, and side orientation.

[0117] The terminal device in this application embodiment can have a variety of options, such as any terminal device such as a candybar phone, a foldable phone, a multi-folding phone, a tablet computer, or a smart screen.

[0118] To enable terminal devices to support the aforementioned multiple types of wireless communication functions, multiple communication systems can be incorporated within the device to implement various communication standards. These standards include, for example, cellular, non-cellular, and satellite communication. Therefore, the communication performance of these multiple standards directly impacts the overall communication performance of the terminal device.

[0119] Figure 3 is a schematic diagram of a communication system of a terminal device according to an embodiment of this application.

[0120] In some embodiments, as shown in FIG3, the terminal device includes: a cellular communication system, a WiFi / BT communication system, and a switching switch. The cellular communication system includes a cellular transceiver, a cellular radio frequency front-end module, and a cellular antenna coupled in sequence. The WiFi / BT communication system includes a WiFi / BT transceiver, a non-cellular radio frequency front-end module, and a non-cellular antenna coupled in sequence. The WiFi / BT transceiver is also coupled to the cellular antenna through the switching switch.

[0121] The switching switch includes a first operating state and a second operating state. In the first operating state, the switching switch connects the cellular RF front-end module and the cellular antenna, allowing the cellular antenna to be used for cellular communication. In the event of a conflict between WiFi communication and BitTorrent communication, the switching switch enters the second operating state. In the second operating state, the switching switch connects the WiFi / BitTorrent transceiver and the cellular antenna, allowing the cellular antenna to be used for BitTorrent communication and the non-cellular antenna to be used for WiFi communication. This achieves the effect of reusing the cellular antenna for BitTorrent communication.

[0122] When WiFi and Bluetooth share a non-cellular antenna, and there is a conflict between Bluetooth and WiFi communication, a switch is used to switch to the unused cellular antenna for Bluetooth or WiFi operation to resolve potential conflicts between Bluetooth and WiFi communication. However, this solution does not improve the performance of either the cellular or non-cellular communication system itself.

[0123] This application provides a terminal device that can improve the performance of the cellular communication system itself by utilizing a non-cellular communication system to assist the cellular communication system. Alternatively, it can improve the performance of the non-cellular communication system itself by utilizing a cellular communication system to assist the non-cellular communication system. This further enhances the communication performance of the terminal device.

[0124] Figure 4A is a schematic diagram of the communication link of a terminal device provided in an embodiment of this application.

[0125] In some embodiments, as shown in FIG4A, the terminal device provided in this application embodiment includes the radio frequency system 1, the first radiator ANT1, and the second radiator ANT2 provided in this application embodiment.

[0126] The radio frequency system 1 includes a first communication standard link and a second communication standard link. The first communication standard link is coupled to a first radiator ANT1, and the second communication standard link is coupled to a second radiator ANT2.

[0127] In this embodiment, the first communication standard and the second communication standard include at least one of the three major categories of communication standards: cellular, non-cellular, and satellite. The first communication standard and the second communication standard can belong to different categories. For example, one of the first and second communication standards may be cellular, and the other non-cellular. Alternatively, one of the first and second communication standards may be cellular, and the other satellite. Or, one of the first and second communication standards may be non-cellular, and the other satellite. The first and second communication standards can also belong to the same category. For example, both the first and second communication standards may be cellular. Alternatively, both the first and second communication standards may be satellite. Or, both the first and second communication standards may be non-cellular. Of course, the first and second communication standards can also be other communication standards. The communication standards illustrated in this embodiment are merely illustrative and not exhaustive.

[0128] When the modems for Tiantong and Xingwang (SkyNet and StarNet) and cellular modems are integrated into a single chip, Tiantong and Xingwang can be considered to operate under the same communication standard as cellular systems. Similarly, when the modems for BeiDou (BeiDou Navigation Satellite System) and non-cellular systems are integrated into a single chip, BeiDou and non-cellular systems can be considered to operate under the same communication standard.

[0129] In some embodiments, the radio frequency system 1 includes a radio frequency signal generation circuit 10, a first tuning circuit TUN1, a second tuning circuit TUN2, and a control node A.

[0130] The first tuning circuit TUN1 is located on the first communication standard link. The first tuning circuit TUN1 includes a first input terminal I1, a first output terminal O1, and a first control terminal S1. The first output terminal O1 is used for coupling with the first radiator ANT1. The second tuning circuit TUN2 is located on the second communication standard link. The second tuning circuit TUN2 includes a second input terminal I2, a second output terminal O2, and a second control terminal S2. The second output terminal O2 is used for coupling with the second radiator ANT2.

[0131] A tuning circuit can be used to adjust the resonant mode of a radiator. The tuning circuit may include multiple branches, each corresponding to a tuning state. Furthermore, the tuning circuit may include one or more tuning devices. When the tuning circuit includes one tuning device, that single tuning device may include multiple tuning modes, each corresponding to a different branch of the tuning circuit. Additionally, when the tuning circuit includes multiple tuning devices, these multiple tuning devices may collectively form multiple branches.

[0132] The radio frequency (RF) signal generation circuit 10 is coupled to the first input terminal I1, the second input terminal I2, and the control node A. The control node A is coupled to the first control terminal S1 and the second control terminal S2. Specifically, the RF signal generation circuit 10 transmits a first communication standard RF signal to the first tuning circuit TUN1 via the first input terminal I1, transmits a second communication standard RF signal to the second tuning circuit TUN2 via the second input terminal I2, and synchronously controls the first tuning circuit TUN1 and the second tuning circuit TUN2 via the control node A. Based on the communication scenario, the RF signal generation circuit 10 synchronously controls the circuit states of the first tuning circuit TUN1 and the second tuning circuit TUN2 via the control node A, thereby achieving assistance or mutual support between the first radiator ANT1 and the second radiator ANT2. Depending on the control signal, the control node A may include one node or multiple nodes; Figure 4A only illustrates one scenario.

[0133] For example, one of the first and second communication standard radio frequency (RF) signals is a cellular RF signal, and the other is a non-cellular RF signal. Alternatively, one of the first and second RF signals is a cellular RF signal, and the other is a satellite RF signal. Or, one of the first and second RF signals is a non-cellular RF signal, and the other is a satellite RF signal. Or, both the first and second RF signals are cellular RF signals. For example, the first RF signal is a mid-high band (MHB) RF signal, and the second RF signal is a low band (LB) RF signal. Alternatively, both the first and second RF signals are non-cellular RF signals. For example, the first RF signal is a WiFi RF signal, and the second RF signal is a BitTorrent RF signal, etc. Or, both the first and second RF signals are satellite RF signals. For example, the first RF signal is a Skycom RF signal, and the second RF signal is a StarNet RF signal, etc.

[0134] For example, the radio frequency signal generation circuit 10 is used to receive first communication standard service information and second communication standard service information, and outputs a control signal to the control node A based on the priority status of the first communication standard service information and the second communication standard service information.

[0135] Communication standard service information includes communication service information and data service information. For example, cellular service information includes different frequency combinations, service cycles, durations, and data service information for cellular networks. Non-cellular service information includes antenna usage, service cycles, durations, and data service information for WiFi, Bluetooth, NFC, GPS, BeiDou, etc. Satellite service information includes antenna usage, service cycles, durations, and data service information for Tiantong, StarNet, etc.

[0136] When the radio frequency system 1 shown in Figure 4A is applied to the terminal device provided in the embodiments of this application, the communication method of the terminal device includes:

[0137] The radio frequency (RF) signal generation circuit 10, based on the first and second communication standard service information, controls the first tuning circuit TUN1 to adjust the first radiator ANT1 to transmit the first communication standard RF signal in a first circuit state via control node A, and controls the second tuning circuit TUN2 to adjust the second radiator ANT2 to transmit the first communication standard RF signal in a second circuit state. For example, the RF signal generation circuit 10 outputs a first control signal to control node A based on the first and second communication standard service information, controlling the first tuning circuit TUN1 to adjust the first radiator ANT1 to transmit the first communication standard RF signal in a first circuit state, and controlling the second tuning circuit TUN2 to adjust the second radiator ANT2 to transmit the first communication standard RF signal in a second circuit state.

[0138] Alternatively, the RF signal generation circuit 10, based on the first and second communication standard service information, controls the first tuning circuit TUN1 in a first circuit state to regulate the first radiator ANT1 to transmit the first communication standard RF signal, and controls the second tuning circuit TUN2 in a third circuit state to regulate the second radiator ANT2 to transmit the second communication standard RF signal. For example, the RF signal generation circuit 10 outputs a second control signal to the control node A based on the first and second communication standard service information, controlling the first tuning circuit TUN1 in a first circuit state to regulate the first radiator ANT1 to transmit the first communication standard RF signal, and controlling the second tuning circuit TUN2 in a third circuit state to regulate the second radiator ANT2 to transmit the second communication standard RF signal.

[0139] Alternatively, the RF signal generation circuit 10, based on the first and second communication standard service information, controls the first tuning circuit TUN1 to adjust the first radiator ANT1 to transmit the second communication standard RF signal in a fourth circuit state via control node A, and controls the second tuning circuit TUN2 to adjust the second radiator ANT2 to transmit the second communication standard RF signal in a third circuit state. For example, the RF signal generation circuit 10 outputs a third control signal to control node A based on the first and second communication standard service information, controlling the first tuning circuit TUN1 to adjust the first radiator ANT1 to transmit the second communication standard RF signal in a fourth circuit state, and controlling the second tuning circuit TUN2 to adjust the second radiator ANT2 to transmit the second communication standard RF signal in a third circuit state.

[0140] At any given time, control node A will only control the first tuning circuit TUN1 and the second tuning circuit TUN2 to be in one of the three states mentioned above. For example, at any given time, control node A will only receive one of the first control signal, the second control signal, and the third control signal. That is, at any given time, the first tuning circuit TUN1 and the second tuning circuit TUN2 will be controlled by the first control signal, the second control signal, or the third control signal, and will not be controlled by two control signals simultaneously.

[0141] Based on this, optionally, the terminal device includes a first scenario that prioritizes the first communication standard (or is considered to exist independently).

[0142] In the first scenario, the radio frequency signal generation circuit 10 outputs a first control signal to the control node A, for example, a control signal that carries an assistance or mutual aid decision. The control node A controls the first tuning circuit TUN1 to be in a first state and the second tuning circuit TUN2 to be in a second state. In the first state, the first tuning circuit TUN1 processes the first communication standard radio frequency signal, and in the second state, the second tuning circuit TUN2 also processes the first communication standard radio frequency signal. At this time, under the control of the control node A, the second tuning circuit TUN2 controls the second radiator ANT2 to assist the first communication standard link in performing first communication standard communication, thereby improving the communication performance of the first communication standard link. For example, if the second tuning circuit TUN2 does not assist, it is in a third circuit state processing the second communication standard radio frequency signal. When the second tuning circuit TUN2 assists, it is in a second circuit state processing the first communication standard service signal. Alternatively, for example, if the second tuning circuit does not assist, the second tuning circuit TUN2 is in a third circuit state processing the radio frequency signal of the second communication standard. When the second tuning circuit TUN2 assists, it is in a second circuit state disconnecting the coupling with the second radiator. For example, the second tuning circuit TUN2 includes a switch; opening the switch disconnects the second radiator to improve the performance of the corresponding frequency band of the first radiator. By identifying the radio frequency signal output by the second radiator ANT2, it can be determined whether the second communication standard link assists the first communication standard link. Alternatively, the terminal device may also include a second scenario where the first and second communication standards coexist.

[0143] In the second scenario, the RF signal generation circuit 10 also outputs a second control signal to the control node A, which carries a decision on assistance or mutual assistance. The control node A controls the first tuning circuit TUN1 to be in a first state and the second tuning circuit TUN2 to be in a third state. In the first state, the first tuning circuit TUN1 processes the RF signal of the first communication standard, and in the third state, the second tuning circuit TUN2 processes the RF signal of the second communication standard. At this time, the first radiator ANT1 transmits the RF signal of the first communication standard, and the second radiator ANT2 transmits the RF signal of the second communication standard. By combining the service information of the first and second communication standards, the assistance or mutual assistance between the first and second communication standard links can be determined. For example, it could be that the first communication standard link assists the second communication standard link, or vice versa. For instance, by detecting the performance of the RF signals output by the first and second communication standard links, it can be determined whether there is assistance or mutual assistance between the two links. Performance can be judged from characteristics such as radiation efficiency, radiation pattern, and gain.

[0144] Alternatively, the terminal device may also include a third scenario that prioritizes the second communication standard (or is considered to exist independently).

[0145] In the third scenario, the RF signal generation circuit 10, for example, also outputs a third control signal to the control node A. This third control signal carries a control signal that carries an assistance or mutual aid decision. The control node A controls the first tuning circuit TUN1 to be in the fourth state and the second tuning circuit TUN2 to be in the third state. In the fourth state, the first tuning circuit TUN1 processes the second communication standard RF signal. At this time, under the control of the control node A, the first tuning circuit TUN1 controls the first radiator ANT1 to assist the second communication standard link in performing second communication standard communication, thereby improving the communication performance of the second communication standard link. If the first tuning circuit TUN1 does not assist, it is in the first circuit state processing the first communication standard RF signal. After assisting, the first tuning circuit TUN1 is in the fourth circuit state processing the second communication standard RF signal. By identifying the RF signal output by the first radiator ANT1, it can be determined whether the first communication standard link assists the second communication standard link.

[0146] Alternatively, for example, the terminal device may also include a fourth scenario where the first and second communication standards coexist.

[0147] In the fourth scenario, RF system 1 enters the default coexistence mode. RF signal generation circuit 10 controls the first tuning circuit TUN1 to process the first communication standard RF signal and controls the second tuning circuit TUN2 to process the second communication standard RF signal. At this time, the first radiator ANT1 transmits the first communication standard RF signal corresponding to the first communication standard service information, and the second radiator ANT2 transmits the second communication standard RF signal corresponding to the second communication standard service information. The first communication standard link and the second communication standard link coexist. The driving method of RF system 1 in coexistence mode can be the same as any driving method in RF system 1 in related technologies. Alternatively, the coexistence control signal can be output to the control node in the driving method described in the second scenario above.

[0148] Based on the above description, in different application scenarios, the RF signal generation circuit 10 makes assistance or mutual assistance decisions based on the first communication standard service information and the second communication standard service information, providing assistance or mutual assistance decisions for cellular to assist non-cellular or non-cellular to assist cellular, and generates matching control signals. Then, the matching control signals are obtained according to the assistance or mutual assistance decisions, and the first tuning circuit TUN1 and the second tuning circuit TUN2 are controlled by the control signals to realize assistance or mutual assistance based on parasitic branches or coupling branches of the radiator, or based on the current intensity ratio of the first communication standard link and the second communication standard link. For example, the corresponding control signals can be obtained by looking up the corresponding switch state table that matches the assistance or mutual assistance decisions and control signals stored internally.

[0149] For example, when using a mobile phone at home, WiFi takes priority. When using a mobile phone outdoors, cellular network takes priority. In weak signal scenarios such as bathrooms or kitchens at home, cellular network takes priority. When using Bluetooth headsets with multiple devices, Bluetooth network takes priority. In navigation scenarios, GPS network takes priority. For satellite calls and satellite SMS, satellite network takes priority. When playing games at home while making cellular calls, cellular and WiFi networks coexist. Other scenarios include cellular and GPS networks coexisting, WiFi and GPS networks coexisting, WiFi and Bluetooth coexisting, cellular and Bluetooth coexisting, satellite and Bluetooth coexisting, and many more scenarios where different network standards are prioritized or coexisted.

[0150] In some embodiments, the operating frequency band of the first radiator ANT1 includes a first frequency band, and the operating frequency band of the second radiator ANT2 includes a second frequency band. The first frequency band and the second frequency band are the same or similar to enhance the assistance or mutual aid effect.

[0151] The concept of "closeness" between the first and second frequency bands can be understood as follows: In the first and second frequency bands, the distance between the starting frequency of the higher frequency band and the ending frequency of the lower frequency band is less than 10% of the center frequency of the higher frequency band (or, the distance is less than or equal to 200MHz). For example, if the first frequency band includes B3 (1.71GHz-1.785GHz) in LTE, and the second frequency band includes L1 (1578.42MHz±1.023MHz) in GPS, then B3 and L1 are adjacent frequency bands, and therefore the first and second frequency bands can be considered close. Alternatively, for example, if the first frequency band includes B40 (2.3GHz-2.4GHz) or B41 (2.496GHz-2.69GHz) in LTE, and the second frequency band includes the WiFi / BT band (2.4GHz-2.485GHz), then B40 or B41 and the WiFi / BT band are adjacent frequency bands, and therefore the first and second frequency bands can be considered close.

[0152] Examples include: Cellular load balancer (LB) supporting cellular MHB; cellular load balancer supporting cellular ultra-high frequency (UHB); cellular load balancer supporting LBS; cellular load balancer supporting satellite. Cellular MHB supporting cellular load balancer; cellular MHB supporting cellular UHB; cellular MHB supporting WiFi 2.4G; cellular MHB supporting BT 2.4G; cellular MHB supporting BLE 2.4G; cellular MHB supporting SLE 2.4G; cellular MHB supporting LBS; cellular MHB supporting satellite. Cellular UHB supporting cellular load balancer; cellular UHB supporting cellular MHB; cellular UHB supporting satellite. WiFi / BT / BLE / SLE 2.4G supporting cellular MHB; WiFi / BT / BLE / SLE 2.4G supporting LBS; WiFi / BT / BLE / SLE 2.4G supporting satellite. WiFi / BT / BLE / SLE 5G supporting satellite. LBS enables cellular MHB, LBS enables WiFi / BT / BLE / SLE 2.4G, and LBS enables satellite.

[0153] In some other embodiments, the operating frequency band of the first radiator ANT1 includes a third frequency band, and the operating frequency band of the second radiator ANT2 includes a fourth frequency band, with the third and fourth frequency bands differing significantly.

[0154] For example, in the third and fourth frequency bands, if the distance between the starting frequency of the higher frequency band and the ending frequency of the lower frequency band is greater than 10% of the center frequency of the higher frequency band (or, the distance is greater than 200MHz), then the third and fourth frequency bands are considered to be significantly different.

[0155] For example, cellular load balancing (LB) supports WiFi / BT / BLE / SLE 2.4G; cellular load balancing supports WiFi / BT / BLE / SLE 5G; cellular MHB supports WiFi / BT / BLE / SLE 5G; cellular UHB supports WiFi / BT / BLE / SLE 2.4G; cellular UHB supports WiFi / BT / BLE / SLE 5G; cellular UHB supports LBS; WiFi / BT / BLE / SLE 2.4G supports cellular UHB; WiFi / BT / BLE / SLE 2.4G supports WiFi / BT / BLE / SLE 5G; WiFi / BT / BLE / SLE 5G supports cellular load balancing; Wi-Fi... i / BT / BLE / SLE 5G assists cellular MHB, WiFi / BT / BLE / SLE 5G assists cellular UHB, WiFi / BT / BLE / SLE 5G assists WiFi / BT / BLE / SLE 2.4G, WiFi / BT / BLE / SLE 5G assists LBS, LBS assists cellular LB, LBS assists cellular UHB, LBS assists WiFi / BT / BLE / SLE 5G, satellite assists cellular LB, satellite assists cellular MHB, satellite assists cellular UHB, satellite assists WiFi / BT / BLE / SLE 2.4G, satellite assists WiFi / BT / BLE / SLE 5G, satellite assists LBS.

[0156] Figure 4B is a radiator distribution diagram of a terminal device provided in an embodiment of this application.

[0157] In some embodiments, a radiator distribution diagram in a terminal device is illustrated in Figure 4B. In the architecture of Figure 4B, the radiator at the top left corner is GPSL1 or WiFi 5G, and the radiator in part of the upper left side frame is MHB. Assistance or cooperation between cellular and non-cellular branches can be achieved at the top left corner and the upper left side frame. The radiator in part of the lower left side frame is LC / WiFi 2.4G / WiFi 5G, and assistance or cooperation between cellular and non-cellular branches can be achieved at the upper left side frame and the lower left side frame. The radiator in the bottom frame is MHB, and the radiator in the lower right side frame is LB. Assistance or cooperation between intracellular branches can be achieved at the bottom and lower right side frames. The radiator in the upper right side frame is LB, and assistance or cooperation between intracellular branches can be achieved at the lower right side frame and the upper right side frame. The radiator in the top right corner frame is GPSL5, and assistance or cooperation between cellular and non-cellular branches can be achieved at the top right corner frame and the upper right side frame. The radiators on the top frame are for WiFi 2.4G / BeiDou / TianTong networks. Assistance or mutual support between non-cellular and satellite nodes can be achieved at the top side frame and the top right corner frame. Assistance or mutual support between non-cellular nodes can be achieved at the top side frame and the top left corner frame. The assistance or mutual support between the various radiators is controlled by the radio frequency system 1 described above in this application embodiment.

[0158] Figure 4B is just an example of a single-screen candybar phone. In different terminal devices, if the layout of adjacent radiators changes, there will be assistance or cooperation between other different services or frequency bands.

[0159] Figure 4C is a schematic diagram of an assistance or mutual aid principle provided in an embodiment of this application.

[0160] When radiators of different communication standards operate independently, even if there is no communication service requirement, there will be coupling current, which will affect the performance of the other radiator.

[0161] As shown in Figure 4C, when the current directions of the assisting radiator and the assisted radiator are opposite, the assisting radiator (e.g., non-cellular) can be directly disconnected (e.g., grounded) through a tuning circuit. In this case, the current intensity of the assisting radiator decreases, and the coupling current becomes extremely small or even zero. Therefore, the performance of the other assisted radiator (e.g., cellular) is improved.

[0162] When the current directions of the assisting radiator and the assisted radiator are the same, the assisting radiator (such as a cellular radiator) acts as a parasitic branch, either entirely or partially, to improve the performance of the assisted radiator (such as a non-cellular radiator). In this case, the assisting radiator can be completely inactive or configured to a tuning state that may result in a performance degradation of M dB.

[0163] In the radio frequency system 1 provided in this application embodiment, both the first tuning circuit TUN1 and the second tuning circuit TUN2 are coupled to and synchronously controlled by control node A. In radio frequency system 1, the radio frequency signal generation circuit 10 controls the state of the first tuning circuit TUN1 and the second tuning circuit TUN2 based on first communication standard service information and second communication standard service information. Based on different service information, the radio frequency signal generation circuit 10 generates different assistance or mutual assistance indications. For example, based on the first and second communication standard service information, the first communication standard is prioritized, and a corresponding first control signal is generated. Control node A controls both the first tuning circuit TUN1 and the second tuning circuit TUN2 to process the first communication standard radio frequency signal. The second tuning circuit TUN2 and the second radiator ANT2 coupled to the second tuning circuit TUN2 assist the first tuning circuit TUN1 and the first radiator ANT1 coupled to the first tuning circuit TUN1 in processing the first communication standard radio frequency signal, which helps to improve the communication performance of the first communication standard, thereby improving the communication performance of the terminal device. Alternatively, for example, based on the service information of the first communication standard and the service information of the second communication standard, it can be determined that the first and second communication standards coexist. Control node A controls the first tuning circuit TUN1 to process the radio frequency signal of the first communication standard and controls the second tuning circuit TUN2 to process the radio frequency signal of the second communication standard. However, at this time, control node A has already controlled the second tuning circuit TUN2 to reduce the radiation performance of the second communication standard and instructed the first tuning circuit TUN1 to increase the radiation performance of the first communication standard (or vice versa). At this time, although the second tuning circuit TUN2 does not assist in processing the radio frequency signal of the first communication standard, it can still improve the performance of the first communication standard, thereby improving the communication performance of the terminal device. For example, based on the service information of the first and second communication standards, it can be determined that the second communication standard takes priority. Control node A controls both the first tuning circuit TUN1 and the second tuning circuit TUN2 to process the radio frequency signal of the second communication standard. The first tuning circuit TUN1 and the first radiator ANT1 coupled to the first tuning circuit TUN1 assist the second tuning circuit TUN2 and the second radiator ANT2 coupled to the second tuning circuit TUN2 in processing the radio frequency signals of the two communication modes, which helps to improve the communication performance of the second communication mode, thereby improving the communication performance of the terminal device.

[0164] For example, the performance of the first communication standard can be determined by assessing its radiation efficiency, radiation pattern, gain, and other characteristics. If the second communication standard link assists or complements the first communication standard link, the communication performance of the second communication standard link itself may or may not decrease. The reverse is also true.

[0165] Figures 5A-5C are schematic diagrams of the communication links of another terminal device provided in the embodiments of this application.

[0166] As shown in Figure 5A, for example, the RF signal generation circuit 10 includes a modem (MOD), an RF chip (RFIC), and an RF front-end module (FEM). The modem (MOD) is coupled to the RF front-end module (FEM) through the RF chip (RFIC), and the RF chip (RFIC) is also coupled to the control node A. The first input terminal I1 of the first tuning circuit TUN1 is coupled to the RF front-end module (FEM), and the first output terminal O1 is used to couple to the first radiator ANT1. The second input terminal I2 of the second tuning circuit TUN2 is coupled to the RF front-end module (FEM), and the second output terminal O2 is used to couple to the second radiator ANT2.

[0167] The signal transmitted by control node A controls the first tuning circuit TUN1 to be in the first circuit state and the second tuning circuit TUN2 to be in the second circuit state. At this time, for example, the terminal device enters the first scenario described above. Alternatively, the signal transmitted by control node A controls the first tuning circuit TUN1 to be in the first circuit state and the second tuning circuit TUN2 to be in the third circuit state. At this time, for example, the terminal device enters the second scenario described above. Or, the signal transmitted by control node A controls the first tuning circuit TUN1 to be in the fourth circuit state and the second tuning circuit TUN2 to be in the third circuit state. At this time, for example, the terminal device enters the third scenario described above.

[0168] In some embodiments, the modem (MOD) is used to receive first communication standard service information and second communication standard service information, and the radio frequency chip (RFIC) is used to control the state of the first tuning circuit (TUN1) and the second tuning circuit (TUN2) through the control node A. For example, the RFIC is used to output a first control signal, a second control signal, or a third control signal to the control node A. The modem (MOD) can, for example, receive communication service information from the communication standard service information, which may include, for example, the usage of antennas at different frequencies, service cycles, and service durations.

[0169] In some embodiments, as shown in FIG5B, the radio frequency chip RFIC includes a first communication standard radio frequency chip RFIC1 and a second communication standard radio frequency chip RFIC2.

[0170] The first communication standard RF IC1 is located on the first communication standard link and is coupled between the modem and the RF front-end module. The second communication standard RF IC2 is located on the second communication standard link and is also coupled between the modem (MOD) and the RF front-end module (FEM).

[0171] For example, one of the first communication standard RF chip RFIC1 and the second communication standard RF chip RFIC2 includes a cellular RF chip, and the other includes a non-cellular RF chip. Alternatively, one of the first communication standard RF chip RFIC1 and the second communication standard RF chip RFIC2 includes a cellular RF chip, and the other includes a satellite RF chip. Alternatively, one of the first communication standard RF chip RFIC1 and the second communication standard RF chip RFIC2 includes a non-cellular RF chip, and the other includes a satellite RF chip. Alternatively, both the first communication standard RF chip RFIC1 and the second communication standard RF chip RFIC2 include cellular RF chips. Alternatively, both the first communication standard RF chip RFIC1 and the second communication standard RF chip RFIC2 include satellite RF chips. Alternatively, both the first communication standard RF chip RFIC1 and the second communication standard RF chip RFIC2 include non-cellular RF chips.

[0172] In the structure shown in Figure 5A, the first communication standard RF IC1 and the second communication standard RF IC2 can be understood as integrated into a single structure, serving as a component of the RF IC. This application does not limit the integration method of the first communication standard RF IC1 and the second communication standard RF IC2, as long as the integrated RF IC can perform the functions of both RF IC1 and RF IC2. In the structure shown in Figure 5B, the first communication standard RF IC1 and the second communication standard RF IC2 are disposed separately.

[0173] For example, as shown in Figure 5B, only the first communication standard RF IC1 is coupled to the control node A. Therefore, regardless of whether the terminal device enters the first, second, or third scenario described above, the first communication standard RF IC1 controls the states of the first tuning circuit TUN1 and the second tuning circuit TUN2 through the control node A. For instance, at any given time, the first communication standard RF IC1 will only output one of the first, second, and third control signals to the control node A; it will not output multiple control signals simultaneously.

[0174] Optionally, as shown in Figure 5B, the second communication standard RF IC2 and the first communication standard RF IC1 can be decoupled. In this case, the modem MOD directly sends all three control signals obtained based on the first and second communication standard service information to the first communication standard RF IC1, which then transmits them to the control node A.

[0175] Alternatively, as shown in Figure 5C, the second communication standard RF IC2 is also coupled to the first communication standard RF IC1. In this case, the modem MOD directly sends a portion of the control signals (e.g., the first control signal) obtained based on the first and second communication standard service information to the first communication standard RF IC1, which then transmits them to control node A. A portion of the control signals (e.g., the third control signal) is sent to the second communication standard RF IC2, which then transmits them back to the first communication standard RF IC1, and finally, the first communication standard RF IC1 sends them to control node A.

[0176] Figures 6A and 6B are schematic diagrams of the communication link of another terminal device provided in the embodiments of this application.

[0177] In some embodiments, as shown in FIG6A, the modem includes a first sub-modem MOD1 and a second sub-modem MOD2. The first sub-modem MOD1 and the second sub-modem MOD2 are coupled together, and are also coupled to an RF chip respectively. The first sub-modem MOD1 is used to receive first communication standard service information, and the second sub-modem MOD2 is used to receive second communication standard service information.

[0178] At this point, the structure of the RF chip can be seen in the description of the RF chip in Figures 5A-5C.

[0179] In Figures 5A-5C, it can be understood that the first sub-modem MOD1 and the second sub-modem MOD2 are integrated into a single structure as components of the modem. This application does not limit the integration method of the first sub-modem MOD1 and the second sub-modem MOD2; the integrated modem MOD only needs to be able to perform the functions of the first sub-modem MOD1 and the second sub-modem MOD2.

[0180] In some embodiments, the first sub-modem MOD1 and the second sub-modem MOD2 are coupled through a first communication path L1. The first sub-modem MOD1 sends first communication standard service information to the second sub-modem MOD2 through the first communication path L1, and the second sub-modem MOD2 sends second communication standard service information to the first sub-modem MOD1 through the first communication path L1.

[0181] For example, the first sub-modem MOD1 includes a first communication interface, and the second sub-modem MOD2 includes a second communication interface. The first and second communication interfaces are coupled through a first communication path L1. The first and second communication interfaces can be, but are not limited to, universal asynchronous receiver / transmitter (UART) interfaces, peripheral component interconnect express (PCIE) interfaces, I3C communication interfaces (improved inter-integrated circuit) interfaces, and interprocess communication (IPC) interfaces, as long as they can realize the transmission of communication information.

[0182] As shown in Figure 6B, the radio frequency (RF) chip includes a first communication standard RF chip RFIC1 and a second communication standard RF chip RFIC2. The second communication standard RF chip RFIC2 can be integrated with the second sub-modem MOD2 into a single structure. Optionally, the first communication standard RF chip RFIC1 can also be integrated with the first sub-modem MOD1 into a single structure to improve the integration of the RF system 1.

[0183] In some embodiments, a first signal path is coupled between the first sub-modem MOD1 and the second sub-modem MOD2, and the first sub-modem MOD1 sends the first operating status information of the first sub-modem MOD1 to the second sub-modem MOD2 through the first signal path.

[0184] For example, the first sub-modem MOD1 includes a first input / output interface, the second sub-modem MOD2 includes a second input / output interface, and a first signal path is coupled between the first input / output interface and the second input / output interface.

[0185] The first and second input / output interfaces can include, for example, general-purpose input / output (GPIO) interfaces, MIPI interfaces, etc., as long as they can be used to implement high / low level, rising edge, or falling edge signal transmission. A rising edge can be understood as the instant from low level to high level, and a falling edge can be understood as the instant from high level to low level.

[0186] For example, the operating states of the first sub-modem MOD1 include ON, OFF, and idle. For instance, the ON, OFF, and idle states of the first sub-modem MOD1 can be characterized by the rising edge, falling edge, and high impedance state of the signal.

[0187] In some embodiments, a second signal path is also coupled between the first sub-modem MOD1 and the second sub-modem MOD2; the first sub-modem MOD1 and the second sub-modem MOD2 transmit timing synchronization information through the second signal path.

[0188] For example, the first sub-modem MOD1 includes a third input / output interface, and the second sub-modem MOD2 includes a fourth input / output interface. A second signal path is coupled between the third and fourth input / output interfaces. The second signal path can be for sending information from the first sub-modem MOD1 to the second sub-modem MOD2, or for sending information from the second sub-modem MOD2 to the first sub-modem MOD1.

[0189] The first sub-modem MOD1 and the second sub-modem MOD2 have their own timing sequences. If they are not synchronized, timing disorders will occur. By setting up a second signal path between the first sub-modem MOD1 and the second sub-modem MOD2 to transmit timing synchronization information, the risk of timing disorders can be reduced.

[0190] In some embodiments, the second sub-modem MOD2 also sends operating status information to the first sub-modem MOD1 through the first communication path L1. The operating status of the second sub-modem MOD2 includes ON, OFF, and idle.

[0191] For example, the second communication standard is non-cellular, and the operating status of the second sub-modem MOD2 includes WiFi 2.4G / 5G on, off, and idle; BT on, off, and idle; GPS L1 / L5 on, off, and idle; and StarFlash on, off, and idle.

[0192] The operation status information of the second sub-modem MOD2 is transmitted through the first communication path L1, which can simultaneously transmit the above-mentioned multiple operation status information and simplify the signal path of the radio frequency system 1.

[0193] In other embodiments, the second sub-modem MOD2 can also transmit the above-mentioned operating status information through multiple third signal paths.

[0194] In some embodiments, the first sub-modem MOD1 also transmits the service cycle and duration to the second sub-modem MOD2 via the first communication path L1. The second sub-modem MOD2 also transmits the service cycle and duration to the first sub-modem MOD1 via the first communication path L1. This is to improve the accuracy of collaborative or mutual decision-making.

[0195] Referring to Table 1, when the first modem is in an "on" state and the second sub-modem MOD2 is in an "off" or "idle" state, it indicates that the first communication standard has control, and the circuit states of the first tuning circuit TUN1 and the second tuning circuit TUN2 are configured with the first communication standard as the priority state. At this time, the second sub-modem MOD2 and the second communication standard RF chip RFIC2 can enter a low-power mode, only occasionally turning on when it is necessary to monitor whether the second communication standard is operating. When the first sub-modem MOD1 is in an "off" or "idle" state and the second sub-modem MOD2 is in an "on" state, it indicates that the second communication standard has control, and the circuit states of the first tuning circuit TUN1 and the second tuning circuit TUN2 are configured with the second communication standard as the priority state. At this time, the first sub-modem MOD1 and the first communication standard RF chip RFIC1 can enter a low-power mode, only occasionally turning on when it is necessary to monitor whether the first communication standard is operating. When both the first sub-modem MOD1 and the second sub-modem MOD2 are enabled, it indicates that the first and second communication standards coexist. The circuit states of the first tuning circuit TUN1 and the second tuning circuit TUN2 are configured as either coexistence, first communication standard priority, or second communication standard priority. When both the first sub-modem MOD1 and the second sub-modem MOD2 are disabled or idle, it indicates that both the first and second communication standards are in sleep mode. The circuit states of the first tuning circuit TUN1 and the second tuning circuit TUN2 are configured as low-power.

[0196] Table 1 State Table of Tuning Circuit

[0197] In the architecture shown in Figures 6A and 6B, the first sub-modem MOD1 determines whether to output the first or second control signal based on the first communication standard service information, the second communication standard service information, the first operating status information, and the second operating status information. The second sub-modem MOD2 determines whether to output the third or second control signal based on the first communication standard service information, the second communication standard service information, the first operating status information, and the second operating status information. For example, if the assistance or cooperation decision is for the second communication standard link to assist the first communication standard link, the first sub-modem MOD1 outputs the second control signal. If the assistance or cooperation decision is for the first communication standard link to assist the second communication standard link, the second sub-modem MOD2 outputs the second control signal. The first, second, and third control signals are all output from the first communication standard radio frequency signal, and only one control signal is output at a time.

[0198] Figure 7 is a schematic diagram of the communication link of another terminal device provided in an embodiment of this application.

[0199] In some embodiments, as shown in FIG7, the radio frequency front-end module (FEM) includes a first sub-radio frequency front-end module (FEM1) and a second sub-radio frequency front-end module (FEM2). The first sub-radio frequency front-end module (FEM1) is coupled between a first communication standard radio frequency chip (RFIC1) and a first tuning circuit (TUN1), and the second sub-radio frequency front-end module (FEM2) is coupled between a second communication standard radio frequency chip (RFIC2) and a second tuning circuit (TUN2). That is, the first sub-radio frequency front-end module (FEM1) and the second sub-radio frequency front-end module (FEM2) are respectively coupled to the radio frequency chips.

[0200] At this point, the structure of the RFIC and MOD, as exemplified, can be found in Figures 5A-5C describing the RFIC and Figures 6A-6B describing the MOD.

[0201] In Figures 5A-6B, it can be understood that the first sub-RF front-end module FEM1 and the second sub-RF front-end module FEM2 are integrated into a single structure as a component of the RF front-end module FEM. This application does not limit the integration method of the first sub-RF front-end module FEM1 and the second sub-RF front-end module FEM2, as long as the integrated RF front-end module FEM can realize the functions of the first sub-RF front-end module FEM1 and the second sub-RF front-end module FEM2.

[0202] In the architecture shown in Figure 7, the working principle of the radio frequency signal generation circuit 10 is the same as that of the architecture shown in Figure 6A.

[0203] Figure 8 is a schematic diagram of the communication link of another terminal device provided in an embodiment of this application.

[0204] In some embodiments, as shown in FIG8, the radio frequency signal generation circuit 10 further includes an arbitration circuit 11, which is coupled to a modem.

[0205] For example, arbitration circuit 11 is used to receive first communication standard service information and second communication standard service information, and based on the first and second communication standard service information, to control the state of the first and second tuning circuits through a control node. For example, arbitration circuit 11 is used to receive the first and second communication standard service information and send a third control signal to the modem MOD.

[0206] For example, arbitration circuit 11 is coupled to first sub-modem MOD1 and second sub-modem MOD2 respectively. Arbitration circuit 11 receives first communication standard service information from first sub-modem MOD1 and second communication standard service information from second sub-modem MOD2. Furthermore, arbitration circuit 11 also receives first operating status information sent by first sub-modem MOD1 and second operating status information sent by second sub-modem MOD2. That is, all information sent by first sub-modem MOD1 to second sub-modem MOD2 (e.g., service information, status information, etc.) is synchronously sent to arbitration circuit 11, and all information sent by second sub-modem MOD2 to first sub-modem MOD1 (e.g., service information, status information, etc.) is also synchronously sent to arbitration circuit 11. During the operation of the terminal device, first sub-modem MOD1 and second sub-modem MOD2 can periodically send service information and operating status information to arbitration circuit 11. For example, arbitration circuit 11 can also send assistance or mutual aid decisions based on the first and second communication standard service information to first sub-modem MOD1 and second sub-modem MOD2.

[0207] In the architecture shown in Figure 8, the arbitration circuit 11 is always on. The arbitration circuit 11 handles service decision-making on the second communication standard link, managing conflicts through assistance or mutual aid. It also temporarily stores service information for both the first and second communication standards, managing both service and status information uniformly. When the first sub-modem MOD1 is not working, the functional modules related to the first communication standard within it can go into sleep mode to conserve power, and uniformly send the first communication standard service information to the arbitration circuit 11 for processing. When the second sub-modem MOD2 is not working, the functional modules related to the second communication standard within it can go into sleep mode to conserve power, and uniformly send the second communication standard service information to the arbitration circuit 11.

[0208] The first sub-modem MOD1 determines whether to output the aforementioned first control signal (or second control signal) based on the first communication standard service information, the second communication standard service information, the first operating status information, and the second operating status information. The arbitration circuit 11 determines whether to output the aforementioned third control signal (or second control signal) based on the first communication standard service information, the second communication standard service information, the first operating status information, and the second operating status information. The first control signal, the second control signal, and the third control signal all have the first communication standard radio frequency signal output, and only one control signal will be output at any given time.

[0209] Based on different architectures, the arbitration circuit 11 can send the third control signal to the first sub-modem MOD1, or the arbitration circuit 11 can send the third control signal to the second communication standard RFIC2, which will then transmit it to the first communication standard RFIC1.

[0210] Arbitration circuit 11 stores service information for the first sub-modem MOD1 and the second sub-modem MOD2. After the first sub-modem MOD1 starts up, it can directly retrieve the previously stored service information for the second sub-modem MOD2 from arbitration circuit 11, without waiting for the second sub-modem MOD2 to transmit service information. This allows for faster decision-making for assistance or mutual aid, improving communication efficiency. Similarly, arbitration circuit 11 stores service information for the first sub-modem MOD1 and the second sub-modem MOD2. After the second sub-modem MOD2 starts up, it can directly retrieve the previously stored service information for the first sub-modem MOD1 from arbitration circuit 11, without waiting for the first sub-modem MOD1 to transmit service information. This allows for faster decision-making for assistance or mutual aid, improving communication efficiency. Furthermore, arbitration circuit 11 already stores the latest service information for the first sub-modem MOD1 and the second sub-modem MOD2. When either the first sub-modem MOD1 or the second sub-modem MOD2 wants to go into sleep mode, it can completely enter sleep mode, saving power.

[0211] Figures 9A and 9B are schematic diagrams of the communication link of another terminal device provided in the embodiments of this application.

[0212] In some embodiments, as shown in FIG9A, the radio frequency signal generation circuit 10 further includes a processor 12, which is coupled to a modem. The processor 12 is used, for example, to receive communication service information sent by the modem, and the processor 12 is also used, for example, to receive data service information sent by other components of the terminal device.

[0213] For example, processor 12 is coupled to a first sub-modem MOD1 and a second sub-modem MOD2, respectively. For instance, processor 12 is used to output scene decision information to the modems. The first sub-modem MOD1 can also transmit the first communication standard service information it receives to processor 12, and the second sub-modem MOD2 can also transmit the second communication standard service information it receives to processor 12.

[0214] For example, processor 12 can determine the terminal device's state (fully unfolded, various folded states, various hovering states, landscape, portrait), and ground tilt angle based on data from multiple sensors. It can also determine whether the terminal device is held in landscape or portrait mode (left-handed, right-handed, left-headed, right-headed, two-handed, not held), and the specific grip position. Furthermore, it can determine if the user is in a walking or running motion. Based on these different states, processor 12 makes scenario decisions, which can determine priorities such as cellular priority, non-cellular priority (e.g., GPS priority, BT priority), satellite priority, cellular and non-cellular coexistence (e.g., cellular and WiFi coexistence, cellular and GPS coexistence, cellular and BT coexistence), and cellular and satellite coexistence. The modem (MOD) then combines these scenario decisions to make further business decisions.

[0215] The processor 12 can also make scenario decisions based on the location of the terminal device. For example, indoors, WiFi is generally prioritized. When the WiFi 5G signal is strong, WiFi 5G is prioritized. When the WiFi 5G signal is weak, WiFi 2G is prioritized. Indoors, where there is frequent switching between WiFi and cellular signals, cellular is generally prioritized. Or, for example, outdoors, cellular is prioritized. In extremely weak field environments (e.g., signal strength below -110dB), the cellular LB band is prioritized. In weak field environments (e.g., signal strength between -100dB and -110dB), the cellular MHB band is prioritized. In medium to strong field environments (e.g., signal strength above -100dB), the cellular UHB band is prioritized.

[0216] The processor 12 can also make scenario-based decisions based on the functional usage of the terminal device. For example, in a GPS navigation scenario, GPS services are prioritized. In a Bluetooth headset scenario, Bluetooth is prioritized. In satellite scenarios (such as BeiDou short message service, Tiantong satellite communication, and Xingwang satellite communication), satellite signals are prioritized. For example, in an ultra-wideband (UWB) car key scenario, UWB signals are prioritized.

[0217] The processor 12 can also make scenario-based decisions based on the usage of application software (APP) in the terminal device. For example, based on the business data flow requirements of the APP, it can determine the radiation performance (or the current intensity ratio) of the two communication standard links.

[0218] In some embodiments, the communication method further includes: the radio frequency signal generation circuit 10 also receives first data service information and second data service information, wherein the first data service information represents the data transmission rate of the first communication standard and the second data service information represents the data transmission rate of the second communication standard.

[0219] The value W represents the ratio of the data transmission rate of the first communication standard to the data transmission rate of the second communication standard. When W equals 1, it indicates that the data transmission rate of the first communication standard is equal to that of the second communication standard, and there is no cooperation or interaction between the first and second communication standard links. The radio frequency signal of the first communication standard is the radio frequency signal when there is no cooperation or interaction, and the radio frequency signal of the second communication standard is the radio frequency signal when there is no cooperation or interaction. When W does not equal 1, it indicates that the data transmission rate of the first communication standard is not equal to that of the second communication standard, and there is cooperation or interaction between the first and second communication standard links.

[0220] When W is greater than 1, the second communication standard link assists the first communication standard link. Therefore, when W is greater than 1, under the control of control node A, the signal strength of the first communication standard radio frequency signal output by the first radiator is greater than the signal strength of the first communication standard radio frequency signal output by the first radiator when W equals 1. The signal strength of the second communication standard radio frequency signal output by the second radiator is less than the signal strength of the second communication standard radio frequency signal output by the second radiator when W equals 1.

[0221] Alternatively, it can be understood that when W is greater than 1, the first communication standard radio frequency signal is assisted, and the signal strength of the first communication standard radio frequency signal is greater than the signal strength when W equals 1 and the first communication standard radio frequency signal is not assisted. The second communication standard radio frequency signal is used to assist, and the signal strength of the second communication standard radio frequency signal is less than the signal strength when W equals 1 and the second communication standard radio frequency signal is not used to assist.

[0222] Similarly, when W is less than 1, the first communication standard link assists the second communication standard link. Therefore, when W is less than 1, under the control of control node A, the signal strength of the first communication standard radio frequency signal output by the first radiator is less than the signal strength of the first communication standard radio frequency signal output by the first radiator when W equals 1. The signal strength of the second communication standard radio frequency signal output by the second radiator is greater than the signal strength of the second communication standard radio frequency signal output by the second radiator when W equals 1.

[0223] Alternatively, it can be understood as follows: when W is less than 1, the first communication standard radio frequency signal is used for assistance; the signal strength of the first communication standard radio frequency signal is less than the signal strength when W equals 1 and the first communication standard radio frequency signal is not used for assistance or mutual assistance. The second communication standard radio frequency signal is used for assistance; the signal strength of the second communication standard radio frequency signal is greater than the signal strength when W equals 1 and the second communication standard radio frequency signal is not used for assistance.

[0224] In short, after assistance or mutual assistance occurs, the signal strength of the assisted radio frequency signal increases, while the signal strength of the assisting radio frequency signal decreases. Signal strength can be determined, for example, by the reference signal receiving power (RSRP).

[0225] For example, indoors, cellular calls and non-cellular web browsing can occur simultaneously, coexisting without mutual assistance. When the non-cellular service switches from web browsing to video playback, the non-cellular data transmission rate increases, requiring cellular assistance. Similarly, cellular web browsing and Wi-Fi screen mirroring can occur simultaneously, again with cellular and non-cellular coexisting without mutual assistance. When the cellular service switches from web browsing to video playback, the cellular data transmission rate increases, requiring non-cellular assistance.

[0226] For example, in the architecture shown in Figure 9A, the control node A determines whether to receive the first control signal or the second control signal directly based on the scenario decision information from the processor 12, without performing real-time arbitration within the modem. This approach is relatively simple.

[0227] Alternatively, as an example, in the architecture shown in Figure 9A, the first sub-modem MOD1 combines scene decision information, first communication standard service information, second communication standard service information, first operating status information, and second operating status information to generate the aforementioned first control signal (or second control signal), which is then sent to control node A by the first communication standard RF IC1. The second sub-modem MOD2 combines scene decision information, first communication standard service information, second communication standard service information, first operating status information, and second operating status information to generate the aforementioned third control signal (or second control signal), which is then sent to control node A by the first communication standard RF IC1. The combined use of the processor 12's scene arbitration and the modem's real-time service arbitration enables accurate assistance or mutual aid decisions based on communication standard service information in real time, resulting in superior communication performance.

[0228] For example, real-time decision-making can be achieved by synchronizing the first sub-modem MOD1 and the second sub-modem MOD2 through timed synchronization information to enable timely responses to assisted or mutually beneficial decisions.

[0229] Alternatively, for example, by taking into account factors such as the processing delay and exception handling time of message communication and handshake between the first sub-modem MOD1 and the second sub-modem MOD2, a certain delay can be set before the output control signal to improve the matching between the assistance or mutual aid decision and the communication standard service information.

[0230] In some embodiments, as shown in FIG9B, the radio frequency signal generation circuit 10 includes a processor 12 and an arbitration circuit 11, with the processor 12 coupled to a modem and the arbitration circuit 11, respectively. For example, the processor 12 is coupled to a first sub-modem MOD1 and the arbitration circuit 11, respectively, and the arbitration circuit 11 and the first sub-modem MOD1 are used to receive scene decision information sent by the processor 12. At this time, the arbitration circuit 11 and the first sub-modem MOD1 also refer to the scene decision information when making service decisions.

[0231] Therefore, under the architecture shown in Figure 9B, the service decision module in the first sub-modem MOD1 and the arbitration circuit 11 will make assistance or mutual assistance decisions based on the scenario decision information, the first communication standard service information, the second communication standard service information, the first working status information and the second working status information, and output the above control signals to the control node A.

[0232] Figures 10A and 10B are schematic diagrams of the communication link of another terminal device provided in the embodiments of this application.

[0233] In some embodiments, as shown in FIG10A, the first communication standard radio frequency chip RFIC1 is coupled to the control node A, and the second communication standard radio frequency chip RFIC2 is also coupled to the control node A.

[0234] The second communication standard RF IC2 is coupled to the control node A. Then, the arbitration circuit 11 generates a third control signal based on scenario decision information, first communication standard service information, second communication standard service information, first operating status information, and second operating status information. The arbitration circuit 11 sends the third control signal to the second communication standard RF IC2. The second communication standard RF IC2 is used to output the third control signal to the control node A. The control node A does not simultaneously receive the first control signal and the third control signal.

[0235] For example, when the first communication standard RF IC1 outputs the first control signal, the second communication standard RF IC2 stops outputting the third control signal. When the second communication standard RF IC2 outputs the third control signal, the first communication standard RF IC1 stops outputting the first control signal. For example, the processor 12 or the arbitration circuit 11 can make the decision to achieve mutual exclusion between the control signals of the first communication link and the control signals of the second communication link.

[0236] For example, the first communication standard is satellite, and the second communication standard is cellular. Or, for example, the first communication standard is satellite, and the second communication standard is non-cellular.

[0237] Mutual exclusion can be achieved through software control, eliminating the need for a switch 13, reducing costs and increasing integration.

[0238] Alternatively, as shown in Figure 10B, the radio frequency system 1 further includes a switching switch 13. The first end of the switching switch 13 is coupled to the first communication standard radio frequency chip RFIC1 and the second communication standard radio frequency chip RFIC2, respectively. The second end of the switching switch 13 is coupled to the control node A, and the third control end of the switching switch 13 is coupled to the first communication standard radio frequency chip RFIC1.

[0239] Switch 13 is used to connect the first communication standard RF IC1 to control node A; or, switch 13 is used to connect the second communication standard RF IC2 to control node A. For example, switch 13, under the control of a third control terminal, connects the first communication standard RF IC1 to control node A, transmitting a first control signal (or a second control signal) to control node A. That is, the first communication standard RF IC1 controls the first tuning circuit TUN1 and the second tuning circuit TUN2. Alternatively, switch 13, under the control of a third control terminal, connects the second communication standard RF IC2 to control node A, transmitting a third control signal to control node A. That is, the second communication standard RF IC2 controls the first tuning circuit TUN1 and the second tuning circuit TUN2.

[0240] The switch 13 is used to switch the control rights of the control node A between the first communication standard link and the second communication standard link. The switch 13 can be, for example, a double-pole double-throw (DPDT) or a double-pole four-throw (DP4T) switch. This application embodiment does not limit the type of switch 13, as long as it can achieve the function of switching communication interfaces.

[0241] In this way, the control signals of the first communication standard link and the second communication standard link can be mutually excluded by switching switch 13, which is beneficial to improving the communication stability of the first communication standard link and the second communication standard link, thereby improving the communication performance of the terminal device.

[0242] In some embodiments, the first sub-modem MOD1 is further configured to send a switching signal to the second sub-modem MOD2. After the first sub-modem MOD1 sends the switching signal to the second sub-modem MOD2, the first communication standard RF IC1 controls the switching switch 13 to open the path between the first communication standard RF IC1 and the control node A, and controls the switching switch 13 to close the path between the second communication standard RF IC2 and the control node A. That is, the first communication standard RF IC1 preempts control of the first tuning circuit TUN1 and the second tuning circuit TUN2.

[0243] Switching signals may include, for example, the operating status information of the first sub-modem MOD1 when it starts up, or the signal generated by the first modem after determining that the first communication modem has priority.

[0244] For example, after the first sub-modem MOD1 sends a switching signal to the second sub-modem MOD2, the first communication standard RFIC1 immediately controls the switching switch 13 to open the path between the first communication standard RFIC1 and the control node A.

[0245] When there is a conflict in the cooperation or mutual assistance decisions between the first sub-modem MOD1 and the second sub-modem MOD2, for example, the first communication mode is activated first, but the second communication mode has not yet been fully released. That is, when the second communication mode RF IC2 is activated,

[0246] The first communication standard RF chip is coupled to the third control terminal of the switch 13, giving it the right to preempt the switch 13. In the event of a conflict between the first sub-modem MOD1 and the second sub-modem MOD2 in a cooperative or collaborative decision-making process—for example, the first communication standard is initiated first, but the second communication standard service has not yet been fully released (i.e., control node A is still coupled to the second communication standard RF chip RFIC2)—the first communication standard RF chip RFIC1 can preempt the control of control node A, directly configure the coupling path of the switch 13, and hardware-wise sever the coupling relationship between the second communication standard RF chip RFIC2 and control node A, allowing the first communication standard RF chip RFIC1 to couple with control node A.

[0247] By giving the first communication standard link the preemptive right of switching switch 13, it is possible to promptly obtain control of the first tuning circuit TUN1 and the second tuning circuit TUN2 when an emergency communication need occurs in the first communication standard link, so that the terminal device can quickly enter the first communication standard communication scenario.

[0248] Alternatively, for example, after the first sub-modem MOD1 sends a switching signal Xms to the second sub-modem MOD2, the first communication standard RFIC1 controls the switching switch 13 to open the path between the first communication standard RFIC1 and the control node A.

[0249] The value of X can be determined by combining factors such as the communication cycle and duration between the first sub-modem MOD1 and the second sub-modem MOD2, the internal service processing duration of the second sub-modem MOD2, and the scheduling duration of the first sub-modem MOD1. For example, X ≤ 10. For instance, X can take values ​​of 10, 9, 8, 7, 6, 5, 4, 3, 2, or 1.

[0250] After the first sub-modem MOD1 sends a switching signal Xms to the second sub-modem MOD2, the first communication standard RF chip RFIC1 preempts the switching switch 13 channel, which can reserve time for the second communication standard link to end the current service, so as to ensure the communication performance of the second communication standard.

[0251] Figures 11A and 11B are schematic diagrams of the communication link of another terminal device provided in the embodiments of this application.

[0252] In some embodiments, as shown in FIG11A, the radio frequency signal generation circuit 10 further includes an arbitration circuit 11. The arbitration circuit 11 is coupled to the modem and the control node A respectively, and is used to receive the first communication standard service information and the second communication standard service information, and send a third control signal to the control node A. Alternatively, it can be understood that the service arbitration task of the second communication standard link is undertaken by the arbitration circuit 11.

[0253] In the architecture shown in Figure 11A, the third control signal generated by the arbitration circuit 11 is directly transmitted to the control node A. For example, the scenario decision information determined by the processor 12 is sent to the arbitration circuit 11 and the first sub-modem MOD1. The first sub-modem MOD1 determines whether the first communication standard has priority. The arbitration circuit 11 includes a service decision module and a control drive module. The service decision module is used to receive scenario decision information, first communication standard service information, second communication standard service information, first working status information, and second working status information, and determine whether to generate an assistance or mutual assistance scheme. If the second communication standard has priority, the service decision module generates an assistance or mutual assistance decision, and the control drive module generates a third control signal based on the assistance or mutual assistance decision.

[0254] For example, the first communication standard RF chip RFIC1 outputs a first control signal, and the arbitration circuit 11 stops outputting a third control signal. When the arbitration circuit 11 outputs the third control signal, the first communication standard RF chip RFIC1 stops outputting the first control signal, thus achieving mutual exclusion between the control signals of the first communication link and the control signals of the second communication link.

[0255] Alternatively, as shown in Figure 11B, the radio frequency system 1 may also include a switching switch 13. The first end of the switching switch 13 is coupled to the first communication standard radio frequency chip RFIC1 and the arbitration circuit 11, respectively; the second end of the switching switch 13 is coupled to the control node A; and the third control end of the switching switch 13 is coupled to the first communication standard radio frequency chip RFIC1.

[0256] For example, switch 13 is used, under the control of the third control terminal, to open the path between the first communication standard radio frequency chip RFIC1 and control node A, and transmit a first control signal (or a second control signal) to control node A. Alternatively, switch 13 is used, under the control of the third control terminal, to open the path between arbitration circuit 11 and control node A, and transmit a third control signal (or a second control signal) to control node A.

[0257] In this way, the control signals of the first communication standard link and the second communication standard link can be mutually excluded by switching switch 13, which is beneficial to improving the communication stability of the first communication standard link and the second communication standard link, thereby improving the communication performance of the terminal device.

[0258] In some embodiments, the modem is also used to send a switching signal to the arbitration circuit 11. For example, after the first sub-modem MOD1 sends a switching signal to the arbitration circuit 11, the first communication standard RF IC1 controls the switching switch 13 to open the path between the first communication standard RF IC1 and the control node A, and controls the switching switch 13 to disconnect the path between the arbitration circuit 11 and the control node A. That is, the first communication standard RF IC1 preempts control of the first tuning circuit TUN1 and the second tuning circuit TUN2.

[0259] By giving the first communication standard link the preemptive right of switching switch 13, it is possible to promptly obtain control of the first tuning circuit TUN1 and the second tuning circuit TUN2 when an emergency communication need occurs in the first communication standard link, so that the terminal device can quickly enter the first communication standard communication scenario.

[0260] In some embodiments, the radio frequency signal generation circuit 10 further includes a processor 12, which is coupled to the arbitration circuit 11 and the first sub-modem MOD1, respectively, and is used to transmit scene decision information to the arbitration circuit 11 and the first sub-modem MOD1, respectively. The simultaneous presence of the processor 12 and the arbitration circuit 11 can achieve dual support for scene recognition and service decision-making, thereby ensuring the accuracy of communication standard priority judgment and accurately improving communication performance.

[0261] It should be understood that the embodiments of this application do not limit the coupling method between the radio frequency signal generation circuit 10 and the control node A. The above various illustrations are merely examples and are not intended to limit anything. Depending on different products and chip architectures, each device in the radio frequency signal generation circuit 10 can serve as a control signal emitting device coupled to the control node A.

[0262] Figures 12A and 12B are schematic diagrams of the communication link of another terminal device provided in the embodiments of this application.

[0263] In some embodiments, the RF chip is coupled to the control node A via a clock path and a data path. The RF chip controls the control node A to control the state of the first tuning circuit TUN1 and the second tuning circuit TUN2 via the clock path and the data path.

[0264] For example, as shown in Figure 12A, the control node includes a first sub-node A1 and a second sub-node A2. The first communication standard RF chip RFIC1 is coupled to the first sub-node A1 through the clock path CLK, and the first communication standard RF signal is also coupled to the second sub-node A2 through the data path DA. The first communication standard RF chip RFIC1 completes the transmission of the first control signal (or the second control signal) through the clock path CLK and the data path DA.

[0265] For example, the first communication standard radio frequency chip RFIC1 includes control interfaces such as the mobile industry processor interface (MIPI). The MIPI is coupled to the first sub-node A1 and the second sub-node A2, and transmits the first control signal to the control node A through the control interfaces such as the MIPI.

[0266] In some embodiments, the arbitration circuit 11 or the second communication standard RF IC2 is also coupled to the first sub-node A1 via the clock path CLK and to the second sub-node A2 via the data path DA, so as to transmit a third control signal through the clock path CLK and the data path DA. For example, the arbitration circuit 11 includes MIPI.

[0267] In other embodiments, the second communication standard RF IC2 is also coupled to the first sub-node A1 via a clock path CLK and to the second sub-node A2 via a data path DA, so as to transmit a third control signal through the clock path CLK and the data path DA. For example, the second communication standard RF IC2 includes MIPI.

[0268] In some embodiments, as shown in FIG12A, the first communication standard link may include a plurality of first tuning circuits TUN1, each of which is coupled to a different first radiator ANT1. Similarly, the second communication standard link may include a plurality of second tuning circuits TUN2, each of which is coupled to a different second radiator ANT2.

[0269] For example, a pair of clock paths (CLK) and data paths (DA) can control a fixed number of modems. Therefore, taking the first communication standard RF IC1 as an example, multiple pairs of clock paths (CLK) and data paths (DA) can be configured on the first communication standard RF IC1. For instance, the first communication standard RF IC1 includes multiple MIPIs, each MIPI controlling a set of tuning circuits, and each set including multiple (e.g., 8) tuning circuits.

[0270] The first communication standard includes multiple frequency bands, and different first tuning circuits TUN1 correspond to different frequency bands. The second communication standard also includes multiple frequency bands, and different second tuning circuits TUN2 correspond to different frequency bands. Therefore, when the first communication standard takes precedence, for communication across different first communication standard frequency bands, the first communication standard RF IC1 can control the second tuning circuit TUN2 to configure different second radiators ANT2 to assist the first radiator ANT1. Similarly, when the second communication standard takes precedence, for communication across different second communication standard frequency bands, the arbitration circuit 11 can control the first tuning circuit TUN1 to configure different first radiators ANT1 to assist the second radiator ANT2.

[0271] When the first communication standard is prioritized, different second radiators ANT2 can be used entirely or partially to assist in improving the performance of the first communication standard. When the second communication standard is prioritized, different first radiators ANT1 can be used entirely or partially to assist in improving the performance of the second communication standard. The assistance or cooperation scheme is flexible and comprehensive to ensure communication effectiveness.

[0272] In some embodiments, the arbitration circuit 11 is coupled to the first sub-modem MOD1 via a second communication path L2, through which the first sub-modem MOD1 sends first communication standard service information, first working status information, etc., to the arbitration circuit 11.

[0273] For example, the first sub-modem MOD1 and the arbitration circuit 11 are each provided with a communication interface, and the two communication interfaces are coupled through the second communication path L2. The communication interface can be, but is not limited to, a UART interface, a PCIe interface, an I3C interface, and an IPC interface, as long as it can realize the transmission of communication information.

[0274] In some embodiments, a third communication path L3 is coupled between the arbitration circuit 11 and the second sub-modem MOD2. The arbitration circuit 11 sends service decision information to the second sub-modem MOD2 through the third communication path L3, and the second sub-modem MOD2 sends second communication mode service information to the arbitration circuit 11 through the third communication path L3.

[0275] For example, the second sub-modem MOD2 and the arbitration circuit 11 are each equipped with a communication interface, and the two communication interfaces are coupled through a third communication path L3. The communication interface can be, but is not limited to, a UART interface, a PCIe interface, an I3C interface, and an IPC interface, as long as it can realize the transmission of communication information.

[0276] In some embodiments, a fourth communication path L4 is coupled between the processor 12 and the first sub-modem MOD1, and the processor 12 sends scene decision information to the first sub-modem MOD1 through the fourth communication path L4.

[0277] For example, the processor 12 and the first sub-modem MOD1 are each provided with a communication interface, and the two communication interfaces are coupled together through a fourth communication path L4. The communication interface can be, but is not limited to, a UART, PCIe interface, I3C interface, and IPC interface, as long as it can realize the transmission of communication information.

[0278] In some embodiments, a fifth communication path L5 is coupled between the processor 12 and the arbitration circuit 11, and the processor 12 sends scenario decision information to the arbitration circuit 11 through the fifth communication path L5.

[0279] For example, the processor 12 and the arbitration circuit 11 are each provided with a communication interface, and the two communication interfaces are coupled through the fifth communication path L5. The communication interface can be, but is not limited to, a UART, PCIe interface, I3C communication interface, and IPC interface, as long as it can realize the transmission of communication information.

[0280] In some embodiments, a sixth communication path L6 is coupled between the processor 12 and the second sub-modem MOD2, and the processor 12 sends scene decision information or other information to the second sub-modem MOD2 through the sixth communication path L6.

[0281] For example, processor 12 and second sub-modem MOD2 are each provided with a communication interface, and the two communication interfaces are coupled through a sixth communication path L6. The communication interface can be, but is not limited to, a UART, PCIe interface, I3C communication interface, and IPC interface, as long as it can realize the transmission of communication information.

[0282] As shown in Figure 12B, when the RF system 1 also includes a switching switch 13, both the clock path CLK and the data path DA are coupled to the switching switch 13.

[0283] Figure 12C is a schematic diagram of the coupling relationship between a switching switch 13, a first tuning circuit TUN1, and a second tuning circuit TUN2 provided in an embodiment of this application.

[0284] For example, as shown in Figure 12C, when the first communication standard RF IC1 and the arbitration circuit 11 each include MIPI, the first communication standard RF IC1 is coupled to the switch 13 through the clock path CLK and the data path DA. The arbitration circuit 11 is also coupled to the switch 13 through the clock path CLK and the data path DA. The first communication standard RF IC1 sends a control signal to the third control terminal of the switch 13 to switch the coupling of the first communication standard RF IC1 with the first control terminal S1 of the first tuning circuit TUN1 and the second control terminal S2 of the second tuning circuit TUN2 through the switch 13. Alternatively, it switches the coupling of the arbitration circuit 11 with the first control terminal S1 of the first tuning circuit TUN1 and the second control terminal S2 of the second tuning circuit TUN2 through the switch 13.

[0285] For example, the first communication standard RF IC1 sends a control signal to the third control terminal of the switch 13, controlling the first communication standard RF IC1 to couple with the first control terminal S1 of the first tuning circuit TUN1 and the second control terminal S2 of the second tuning circuit TUN2 through the switch 13. At this time, based on the physical structure of the switch 13, regardless of whether the arbitration circuit 11 sends a control signal to the switch 13, the communication between the first communication standard RF IC1 and the switch 13 is not affected, thus reducing the requirements for software control.

[0286] In some embodiments, as shown in FIG12A, the radio frequency system further includes a system-on-chip (SOC) arbitration circuit 11 disposed within the SOC; the SOC is coupled to the first sub-node A1 and the second sub-node A2 via a clock path CLK and a data path DA. For example, the SOC includes a MIPI, and the arbitration circuit 11 is coupled to the MIPI of the SOC, and coupled to the first sub-node A1 and the second sub-node A2 via the MIPI of the SOC.

[0287] In some embodiments, as shown in FIG12A, the arbitration circuit 11 is disposed within the SOC. For example, the arbitration circuit 11 is disposed within the microcontroller unit (MCU) within the SOC. For example, one or more of the communication interfaces included in the arbitration circuit 11 may be communication interfaces on the SOC. Integrating the arbitration circuit 11 within the SOC can improve the integration of the terminal device.

[0288] In other embodiments, the arbitration circuit 11 is integrated within the MCU but located outside the SOC. In this case, the MCU may include a MIPI, and the arbitration circuit 11 is coupled to the MCU's MIPI, and coupled to the first child node A1 and the second child node A2 via the MCU's MIPI. Of course, when the arbitration circuit 11 is a separate chip, the arbitration circuit 11 may include a MIPI.

[0289] Figures 13-23 are schematic diagrams of an integration method of a terminal device provided in an embodiment of this application.

[0290] In some embodiments, based on any of the above-described radio frequency system 1 structures, one or more of the processor 12, arbitration circuit 11, first sub-modem MOD1, second sub-modem MOD2, first communication standard radio frequency chip RFIC1, second communication standard radio frequency chip RFIC2, first sub-radio frequency front-end module FEM1, and second sub-radio frequency front-end module FEM2 can be integrated into the SOC to improve the integration of the terminal device.

[0291] As shown in Figure 13, for example, processor 12 is integrated within the SOC to improve the integration of the terminal device.

[0292] Alternatively, as shown in Figure 14, the first sub-modem MOD1 is integrated within the SOC to improve the integration of the terminal device.

[0293] Alternatively, as shown in Figure 15, the arbitration circuit 11 is integrated into the SOC to improve the integration of the terminal device.

[0294] Alternatively, as an example, the second sub-modem MOD2 is integrated within the SOC to improve the integration of the terminal device.

[0295] Alternatively, as shown in Figure 16, the first sub-modem MOD1 and the second sub-modem MOD2 are integrated into the SOC after being integrated into a modem, thereby improving the integration of the terminal device.

[0296] Alternatively, as shown in Figure 17, the first sub-modem MOD1 and the second sub-modem MOD2 are integrated into a modem, but located outside the SOC, to improve the integration of the terminal device.

[0297] Alternatively, as an example, the first sub-modem MOD1 and the second sub-modem MOD2 are set up separately and integrated within the SOC to improve the integration of the terminal device.

[0298] Alternatively, as shown in Figure 18, the arbitration circuit 11, the first sub-modem MOD1, and the second sub-modem MOD2 are integrated into a single structure within the SOC to improve the integration of the terminal device.

[0299] Alternatively, as shown in Figure 19, the arbitration circuit 11, the first sub-modem MOD1, and the second sub-modem MOD2 are integrated into a single structure, but located outside the SOC, to improve the integration of the terminal device.

[0300] Alternatively, as shown in Figure 12A, the processor 12, the first sub-modem MOD1, and the arbitration circuit 11 are set separately but are all integrated within the SOC to improve the integration of the terminal device.

[0301] Alternatively, for example, the processor 12, the first sub-modem MOD1, the second sub-modem MOD2, and the arbitration circuit 11 are set separately, but are all integrated within the SOC to improve the integration of the terminal device.

[0302] Alternatively, as shown in Figure 20, the arbitration circuit 11 and the second sub-modem MOD2 are integrated into a single structure within the SOC to improve the integration of the terminal device.

[0303] Alternatively, as shown in Figure 21, the arbitration circuit 11 and the second sub-modem MOD2 are integrated into a single structure, but located outside the SOC, to improve the integration of the terminal device.

[0304] In this scenario, the first sub-modem MOD1 can be located inside or outside the SOC. Figures 20 and 21 illustrate the case where the first sub-modem MOD1 is located outside the SOC.

[0305] Arbitration circuit 11 and second sub-modem MOD2 are integrated into one structure, and the second communication standard RF chip RFIC2 has control over control node A. When the first communication standard RF chip RFIC1 does not output control signals to control node A, the first communication standard RF chip RFIC1 can go into sleep mode to save power consumption.

[0306] Alternatively, as shown in Figure 22, the arbitration circuit 11 and the first sub-modem MOD1 are integrated into a single structure within the SOC to improve the integration of the terminal device.

[0307] Alternatively, as shown in Figure 23, the arbitration circuit 11 and the first sub-modem MOD1 are integrated into a single structure, but located outside the SOC, to improve the integration of the terminal device.

[0308] In this scenario, the second sub-modem MOD2 can be located inside or outside the SOC. Figures 22 and 23 illustrate the case where the second sub-modem MOD2 is located outside the SOC.

[0309] After the arbitration circuit 11 and the first sub-modem MOD1 are integrated into a single structure, the arbitration circuit 11 and the first sub-modem MOD1 can share the clock path CLK and data path DA of the first communication standard radio frequency chip RFIC1. When the first sub-modem MOD1 is in sleep mode, the arbitration circuit 11 in the integrated structure remains on.

[0310] Alternatively, for example, the first communication standard RF chip RFIC1 is integrated within the SOC, and the first communication standard RF chip RFIC1 can be coupled to the control node A through the SOC's MIPI. Of course, the first communication standard RF chip RFIC1 can also be a separate chip, and the first communication standard RF chip RFIC1 includes MIPI.

[0311] Alternatively, as an example, the second communication standard RF chip RFIC2 is integrated into the SOC. Of course, the second communication standard RF chip RFIC2 can also be a separate chip.

[0312] In summary, in the radio frequency system provided in this application embodiment, the processor 12 can, for example, make scenario decisions based on received data service information.

[0313] The first sub-modem MOD1 determines whether to make the service decision itself based on its first operating status information, the second operating status information of the second sub-modem MOD2, and the scenario decision information. The arbitration circuit 11 determines whether to make the service decision itself based on the first operating status information of the first sub-modem MOD1, the second operating status information of the second sub-modem MOD2, and the scenario decision information.

[0314] When it is determined that the service decision is made by the first sub-modem MOD1, the first sub-modem MOD1 makes a service decision based on scenario decision information, first communication standard service information, second communication standard service information, and second operating status information, and outputs a first control signal or a second control signal based on the service decision. For example, when the first sub-modem MOD1 is activated, the service decision is made by the first sub-modem MOD1. When the second sub-modem MOD2 is not activated, the first sub-modem MOD1 outputs a first control signal with a decision to assist or cooperate. When the second sub-modem MOD2 is activated, the first sub-modem MOD1 outputs a second control signal with a decision to assist or cooperate.

[0315] At this time, the first communication standard radio frequency chip RFIC1 controls the switching switch 13 to open the MIPI of the first communication standard radio frequency chip RFIC1 to the first sub-node A1 and the second sub-node A2, thereby realizing the control of the first tuning circuit TUN1 and the second tuning circuit TUN2.

[0316] When it is determined that the arbitration circuit 11 will make the service decision, the arbitration circuit 11 makes the service decision based on scenario decision information, first communication standard service information, and second communication standard service information, and outputs a third control signal based on the service decision. For example, when the first sub-modem MOD1 is off or idle, and the second sub-modem MOD2 is on, the arbitration circuit 11 makes the service decision and outputs a third control signal with assistance or mutual assistance decision based on the service decision. When the first sub-modem MOD1 and the second sub-modem MOD2 are on, the arbitration circuit 11 makes the service decision and outputs a second control signal with assistance or mutual assistance decision based on the service decision.

[0317] At this time, the first communication standard radio frequency chip RFIC1 controls the switching switch 13 to conduct the path from the MIPI coupled to the arbitration circuit 11 to the first sub-node A1 and the second sub-node A2, thereby realizing the control of the first tuning circuit TUN1 and the second tuning circuit TUN2.

[0318] Under different architectures, the coupling between the arbitration circuit 11 and the first sub-node A1 and the second sub-node A2 can be switched to the coupling between the second communication standard RF IC2 and the first sub-node A1 and the second sub-node A2, or the coupling between the first communication standard RF IC1 and the first sub-node A1 and the second sub-node A2 can be achieved through the first communication standard RF IC1.

[0319] Through the control of the radio frequency system 1, the terminal device can be placed in the first scenario, the second scenario, the third scenario, or enter the fourth scenario of the default mode.

[0320] In some embodiments, the radio frequency system 1 is further configured to adjust service decisions based on the signal strength of the first communication standard radio frequency signal output by the first radiator ANT1 and / or the signal strength of the second communication standard radio frequency signal output by the second radiator ANT2.

[0321] By performing closed-loop feedback on the radio frequency signals after executing assistance or mutual aid decisions, it is determined whether the actual assistance or mutual aid situation has met expectations, thereby determining whether business decisions need to be adjusted to improve the communication performance of terminal devices. For example, processor 12 determines whether the scenario decision is accurate based on the closed-loop feedback results. Modem MOD determines whether the business decision is accurate based on the closed-loop feedback results.

[0322] The above illustration uses an example where the radio frequency system 1 includes a first communication standard link and a second communication standard link. The radio frequency system 1 may also include a third communication standard link. In this architecture, the first communication standard link and / or the second communication standard link can assist the third communication standard link. Alternatively, the first communication standard link and / or the third communication standard link can assist the second communication standard link. Or, the second communication standard link and / or the third communication standard link can assist the first communication standard link. The principle of assistance or mutual assistance is the same as described above and will not be repeated here.

[0323] For example, the radio frequency system 1 also includes a third tuning circuit, which includes a third input terminal, a third output terminal, and a fourth control terminal. The third input terminal is coupled to the radio frequency signal generation circuit 10, the third output terminal is used for coupling with the third radiator, and the fourth control terminal is coupled to the control node A. The radio frequency signal generation circuit 10 is also used to receive third communication standard service information, output a fourth control signal to the control node A, control the first tuning circuit TUN1 to be in a first state, control the second tuning circuit TUN2 to be in a second state, and control the third tuning circuit to be in a fifth state. In the first state, the first tuning circuit TUN1 is used to process the first communication standard radio frequency signal, the second tuning circuit TUN2 is used to process the first communication standard radio frequency signal in the second state, and the third tuning circuit is used to process the first communication standard radio frequency signal in the fifth state. In this case, the first communication standard takes priority, and the fourth control signal can control the second and third tuning circuits to assist the first tuning circuit in processing the first communication standard radio frequency signal, so as to realize the assistance of the second radiator ANT2 and the third radiator to the first radiator ANT1, and improve the performance of the first communication standard radio frequency signal. For example, the first communication standard is satellite, while the second and third communication standards are cellular and non-cellular, respectively.

[0324] Based on the service information of the first communication standard, the service information of the second communication standard, and the service signal of the third communication standard, the priority of the first communication standard is determined, and a corresponding fourth control signal is generated. The fourth control signal controls the first tuning circuit TUN1, the second tuning circuit TUN2, and the third tuning circuit to all process the radio frequency signal of the first communication standard. The second tuning circuit TUN2 and the second radiator ANT2 coupled to it, and the third tuning circuit and the third radiator coupled to it, jointly assist the first tuning circuit TUN1 and the first radiator ANT1 coupled to it in processing the radio frequency signal of the first communication standard, which helps to improve the communication performance of the first communication standard, thereby improving the communication performance of the terminal device.

[0325] The following is a specific example illustrating radio frequency system 1. In this example, the first communication standard is cellular, and the second communication standard is non-cellular.

[0326] When a user uses the terminal device outdoors, the processor 12 prioritizes cellular connectivity in the scene decision. The first sub-modem MOD1 is in an "on" state, while the second sub-modem MOD2 is in a "off" state. Based on the cellular-priority scene decision, the first communication standard service information, and the second communication standard service information, the first sub-modem MOD1 makes a decision to enable GPS-assisted MHB and retrieves the corresponding waveform's first control signal from a table. This first control signal controls the circuit states of the first tuning circuit TUN1 and the second tuning circuit TUN2 via control node A, thereby enabling GPS-assisted MHB and improving its communication performance.

[0327] When a user uses a terminal device indoors, the processor 12 prioritizes non-cellular scenarios. The first sub-modem MOD1 is in an off state, while the second sub-modem MOD2 is in an on state. The arbitration circuit 11, based on the non-cellular scenario decision, the first communication standard service information, and the second communication standard service information, makes a decision to enable MHB to assist WiFi 5G and retrieves the corresponding waveform's third control signal from a table. This third control signal controls the circuit states of the first tuning circuit TUN1 and the second tuning circuit TUN2 through control node A, thereby enabling MHB to assist WiFi 5G and improving its communication performance.

[0328] When a user uses a terminal device indoors, making a cellular call while browsing the web, the processor 12 prioritizes cellular connectivity. The first sub-modem MOD1 and the second sub-modem MOD2 are both enabled. Based on the cellular priority scenario decision, the first communication standard service information, and the second communication standard service information, the first sub-modem MOD1 makes a decision to enable WiFi 5G to assist the MHB (Mean Internet Broadband), and retrieves the corresponding waveform's second control signal from a table. This second control signal controls the circuit states of the first tuning circuit TUN1 and the second tuning circuit TUN2 through control node A, thereby reducing WiFi 5G radiation performance and increasing MHB radiation performance, thus enabling WiFi 5G to assist the MHB and improving its communication performance.

[0329] When a user uses a terminal device indoors, making a cellular call while watching a video, the processor 12 prioritizes non-cellular functionality. The first sub-modem MOD1 and the second sub-modem MOD2 are both enabled. The arbitration circuit 11, based on the non-cellular priority scenario decision, the first communication standard service information, and the second communication standard service information, makes a decision to enable MHB to assist WiFi 5G and retrieves the corresponding waveform's second control signal from a table. This second control signal controls the circuit states of the first tuning circuit TUN1 and the second tuning circuit TUN2 through control node A, thereby reducing MHB radiation performance and increasing WiFi 5G radiation performance, thus enabling MHB to assist WiFi 5G and improving WiFi 5G communication performance.
