[0020] In order to make the objectives, technical solutions and advantages of the present application clearer, the implementation methods of the present application will be further described in detail below with reference to the accompanying drawings.
[0021] The term "multiple" as used herein refers to two or more than two. "And / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. The character " / " generally indicates that the related objects are in an "or" relationship.
[0022] Please refer to Figure 1 , which shows a schematic diagram of a satellite communication module provided by an exemplary embodiment of the present application. The satellite communication module includes: a controller 1010, a radio frequency transceiver 1020 and n satellite communication transceiver paths, where n is an integer greater than or equal to 2, wherein the internal structure of each satellite communication transceiver path is the same, and the satellite communication transceiver path 1030 is taken as an example for description.
[0023] The satellite communication transceiver path 1030 includes a satellite communication power amplifier (PA) 1031, a low noise amplifier (LNA) 1032, and at least two antenna common terminals, different antenna common terminals are connected to different antennas, and different antennas are set in different directions. The at least two antenna common terminals include an antenna common terminal 1033, and the antenna common terminal 1033 is used to connect an antenna (ANT) 1041. Antenna 1041 and antenna 1042 are set at different positions of terminal 1050, antenna 1041 is set at the top of the middle frame of terminal 1050, and antenna 1042 is set at the bottom of the middle frame of terminal 1050.
[0024] The RF transceiver 1020 is connected to n satellite communication transceiver paths respectively. In the satellite communication transceiver path 1030 , the RF transceiver 1020 is connected to a PA 1031 and an LNA 1032 .
[0025] Controller 1010 is used to select m target satellite communication transceiver paths from n satellite communication transceiver paths, where m is a positive integer less than or equal to n, that is, to select satellite communication transceiver path 1030 and satellite communication transceiver path 1060 from n satellite communication transceiver paths, where the value of m is 2 and the value of n is greater than 2.
[0026] The controller 1010 is also used to determine the main antenna common terminal and the diversity antenna common terminal corresponding to each target satellite communication transceiver channel. The antenna connected to the main antenna common terminal is the main antenna, which is used to transmit and receive signals, and the antenna connected to the diversity antenna common terminal is the main antenna, which is used to receive signals. Taking the satellite communication transceiver channel 1031 as an example, the corresponding host antenna common terminal is the antenna common terminal 1033, and the other antenna common terminals corresponding to the satellite communication transceiver channel 1031 are the diversity antenna common terminals. Therefore, antenna 1041 is the main antenna, and antenna 1042 is the diversity antenna. The main antenna 1041 is connected to PA1031 through the antenna common terminal 1033 for transmitting and receiving signals, and the diversity antenna 1042 is connected to LNA1032 through the corresponding antenna common terminal for receiving signals. Among them, an LNA can be integrated inside PA1031, so the main antenna 1041 that is not connected to LNA1032 can realize the function of receiving signals.
[0027] The controller 1010 is also used to control the m target satellite communication transceiver paths to be in working state, control the RF transceiver 1020 to transmit RF signals to the m target satellite communication transceiver paths, and control the satellite communication power amplifier to be connected to the common end of the main antenna, and control the low noise amplifier to be connected to the common end of the diversity antenna. For example, when m is 2, the controller 1010 controls the satellite communication transceiver path 1030 and the satellite communication transceiver path 1060 to be in working state, and controls the RF transceiver 1020 to transmit RF signals to the satellite communication transceiver path 1030 and the satellite communication transceiver path 1060. After determining that the satellite communication transceiver path 1030 is in working state, the controller 1010 controls the main antenna 1041 to be connected to the PA 1031 through the antenna common end 1033, so that the signal is subsequently transmitted through the main antenna 1041 after the PA amplifies the power of the transmission signal.
[0028] It should be noted that, in some implementations, the controller 1010 may be integrated into the RF transceiver 1020 , or may not be integrated into the RF transceiver 1020 .
[0029] To summarize, in the embodiment of the present application, the controller selects m from n satellite communication transceiver paths, and controls the m satellite communication transceiver paths to be in working state. Subsequently, the controller determines the antenna common end for each satellite communication transceiver path in working state, including the antenna common end of the main antenna and the antenna common end of the diversity antenna, wherein the antenna common end of the main antenna is connected to the main antenna, and the antenna common end of the diversity antenna is connected to the diversity antenna. Finally, the controller controls the RF transceiver to receive and send RF signals. Among the m satellite communication transceiver paths, the path insertion loss requirement of a single satellite communication transceiver path is reduced, so a single satellite communication transceiver path can select at least two antennas for reasonable layout to avoid signal quality degradation due to performance problems of a single antenna, thereby ensuring the signal quality of satellite communication.
[0030] Among n satellite communication transceiver paths, after a single satellite communication transceiver path is determined to be in working state, it is necessary to select from at least two antenna common ends and use an antenna with good connection performance to perform satellite communication.
[0031] In some embodiments, the satellite communication transceiver path selects the antenna through a switch component, which is located between the PA and the antenna common terminal, and between the LNA and the antenna common terminal. The controller controls the switch component to connect the PA to the main antenna common terminal and the LNA to the diversity antenna common terminal.
[0032] When the terminal device is in landscape mode or held, the RF signals received and sent by the antenna are unstable. Therefore, the controller selects the antenna common terminal by controlling the switch component to ensure that the antenna connected to the antenna common terminal has good performance and the satellite communication signal quality is high.
[0033] In some embodiments, the controller selects m target satellite communication transceiver paths from n satellite communication transceiver paths according to the terminal holding state, and the main antenna common end and diversity antenna common end corresponding to each target satellite communication transceiver path.
[0034] Some antennas on the terminal may be blocked due to holding, and the antennas corresponding to a single satellite communication transceiver path may all be in a blocked position. Therefore, the controller first determines the satellite communication transceiver path with an unblocked antenna as the target satellite communication transceiver path, and then determines the main antenna common end and the diversity antenna common end corresponding to each target satellite communication transceiver path.
[0035] Please refer to Figure 2, which shows a schematic diagram of an implementation of an antenna selection process provided by an exemplary embodiment of the present application. The terminal includes 6 antennas. When the terminal is in a holding state, antenna 204, antenna 205 and antenna 206 are blocked, and antenna 201, antenna 202 and antenna 203 are not blocked. Therefore, the controller selects the satellite communication transceiver paths corresponding to antenna 201, antenna 202 and antenna 203 as the target satellite communication transceiver paths.
[0036] In one possible implementation, the controller first determines the obstruction condition of each antenna according to the holding state of the terminal and the setting orientation of each antenna. For example, the terminal uses a capacitive sensor to detect the holding state, and then when there is at least one unobstructed antenna in the satellite communication transceiver path, the satellite communication transceiver path is determined as the target satellite communication transceiver path.
[0037] For example, Figure 2 As shown, antenna 201 and antenna 202 correspond to satellite communication transceiver path 2021, antenna 203 and antenna 206 correspond to satellite communication transceiver path 2022, and antenna 204 and antenna 205 correspond to satellite communication transceiver path 2023. Two antennas of satellite communication transceiver path 2021 are unobstructed antennas, one antenna of satellite communication transceiver path 2022 is unobstructed, and there is no unobstructed antenna of satellite communication transceiver path 2023. The controller determines satellite communication transceiver path 2021 and satellite communication transceiver path 2022 as target satellite communication transceiver paths.
[0038] After determining the target satellite communication transceiver path, the controller determines the main antenna and diversity antenna corresponding to each target satellite communication transceiver path. Since the antenna corresponds to the antenna common terminal one by one, the controller selects the main antenna common terminal and the diversity antenna common terminal by controlling the switch component to determine the main antenna and the diversity antenna.
[0039] The target satellite communication transceiver channel may correspond to at least two unobstructed antennas, so the controller determines that the main set of antennas can be divided into the following two situations.
[0040] Case 1: When there is an unobstructed antenna in the target satellite communication transceiver path, the unobstructed antenna is determined as the main antenna corresponding to the target satellite communication transceiver path.
[0041] For example, Figure 2 As shown, the controller determines the satellite communication transceiver path 2021 and the satellite communication transceiver path 2022 as the target satellite communication transceiver paths. Among them, only one antenna of the satellite communication transceiver path 2022 is not blocked, that is, antenna 203, and the controller determines antenna 203 as the main antenna.
[0042] Case 2: When there are at least two unobstructed antennas in the target satellite communication transceiver path, the main antenna corresponding to the target satellite communication transceiver path is determined from the at least two unobstructed antennas based on the antenna performance parameters of each antenna, and the antenna performance parameters include at least one of efficiency, isolation and gain.
[0043] For example, Figure 2 As shown, the satellite communication transceiver path 2022 corresponds to two unobstructed antennas, namely antenna 201 and antenna 202. The controller determines that the performance of antenna 201 is better than that of antenna 202 based on at least one parameter of the antenna's efficiency, isolation, and gain, and then determines that antenna 201 is the primary antenna.
[0044] It should be noted that the performance parameters used to measure antenna performance may also include directivity, polarization mode, etc., which are not limited in the embodiments of the present application.
[0045] In some embodiments, after determining the main antenna and the target satellite communication transceiver path, control determines that the other antennas except the main antenna in the single target satellite communication are diversity antennas, corresponding to the diversity antenna common end.
[0046] For example, Figure 2 In the figure, antenna 201 is a main antenna, antenna 202 is a diversity antenna, antenna common terminal 2031 is a main antenna common terminal, and antenna common terminal 2032 is a diversity antenna common terminal.
[0047] There may be one or more diversity antennas. In a possible implementation, the terminal selects a diversity antenna common terminal corresponding to a diversity antenna with good performance according to performance parameters of the diversity antenna, and connects the common terminal to the LNA.
[0048] In an embodiment of the present application, the controller determines the antenna obstruction condition based on the terminal holding state, and then determines the satellite communication transceiver path with an unobstructed antenna as the target satellite communication transceiver path, and then, based on the antenna performance parameters, determines the antenna with the best performance in each target satellite communication transceiver path as the main antenna, thereby improving the quality of the satellite communication signal.
[0049] In addition to the terminal holding state, the transmission power of each satellite communication receiving and transmitting channel will also affect the quality of satellite communication. Unlike cellular communication, satellite communication requires a larger transmission power due to the long communication distance. The total transmission power of the satellite communication module needs to reach the satellite communication transmission power threshold.
[0050] Optionally, the controller may determine the transmit power of the target satellite communication transceiver path based on the satellite communication transmit power threshold and m, wherein the total transmit power of the m target satellite communication transceiver paths is greater than or equal to the satellite communication transmit power threshold.
[0051] In a possible implementation, the controller calculates the transmission power required to be achieved by each target satellite communication transceiver path according to the combined gains of the m target satellite communication transceiver paths and the satellite communication transmission power threshold.
[0052] In the embodiment of the present application, the satellite communication transmission power threshold is 36.5dBm.
[0053] In some embodiments, the combined gain is calculated by the combined gain formula 101g(m) from m. The combined gain of two target satellite communication transceiver paths is about 3dBm, the combined gain of three target satellite communication transceiver paths is about 5dBm, and the combined gain of four target satellite communication transceiver paths is about 6dBm.
[0054] In some embodiments, the total transmission power of the target satellite communication transceiver path is obtained according to the sum of the transmission power of a single target satellite communication transceiver path and the combining gain, wherein the transmission power of each target satellite communication transceiver path is equal.
[0055] From the above reasoning, it can be seen that in the embodiment of the present application, when there are two target satellite communication transceiver paths, the transmission power of the target satellite communication transceiver paths is 33.5dBm; when there are three target satellite communication transceiver paths, the transmission power of the target satellite communication transceiver paths is 31.5dBm; when there are four target satellite communication transceiver paths, the transmission power of the target satellite communication transceiver paths is 30.5dBm.
[0056] In some embodiments, there is no combining gain, that is, m=1.
[0057] For example, Figure 3 As shown, the satellite communication module includes a satellite communication transceiver path 301, a satellite communication transceiver path 302, and a satellite communication transceiver path 303. When n=3 and m=1, the controller controls the satellite communication transceiver path 302 to be in a working state with a transmission power of 36.5dBm, and the satellite communication transceiver path 301 and the satellite communication transceiver path 303 to be in a non-working state with a transmission power of 0dBm.
[0058] It should be noted that the number of satellite communication transceiver channels in working state can be greater than four, and the satellite communication transmission power threshold is the minimum transmission power requirement for satellite communication. The total transmission power of the satellite communication module can be greater than 36.5dBm, and the transmission power in each channel can also be greater than the calculated result as described above.
[0059] In the case of poor communication quality, in order to improve communication quality, the transmission power of each target satellite communication transceiver path needs to be appropriately increased. Therefore, the controller can also determine the transmission power of the target satellite communication transceiver path based on the current satellite communication quality, the satellite communication transmission power threshold and m, wherein the total transmission power of the m target satellite communication transceiver paths is greater than or equal to the satellite communication transmission power threshold.
[0060] In a possible implementation, the controller first determines the reference transmit power of each target satellite communication transceiver channel according to the satellite communication transmit power threshold and the number of satellite communication transceiver channels, and then, if the satellite communication quality does not meet the communication quality index, increases the transmit power based on the reference transmit power, thereby obtaining the transmit power of the target satellite communication transceiver channel. The reference transmit power is the transmit power of each satellite communication transceiver channel calculated according to the combiner gain.
[0061] In a possible implementation, the worse the current satellite communication quality is, the greater the transmission power of the target satellite communication transceiver path is.
[0062] Regarding the measurement of the current satellite communication quality, in one possible implementation, the terminal determines the current satellite communication quality through communication signal quality measurement indicators such as the current signal SINR (Signal to Interference plus Noise Ratio), RSRP (Reference Signal Receiving Power) and RSSI (Received Signal Strength Indication).
[0063] In addition, the terminal can also change the layout position of the antenna to reduce the possibility of the antenna being blocked. According to the user's holding habits, the lower part of the terminal is more likely to be held than the upper part of the terminal. In the embodiment of the present application, the antenna connected to the antenna common terminal can be located in the upper area of the terminal.
[0064] In a possible usage scenario, when making a satellite call, the user holds the lower area of the terminal, the upper antenna of the terminal is not affected by the holding, and the satellite communication signal quality is good.
[0065] It should be noted that when the distance between the two antennas is close, antenna coupling is likely to occur during the communication process, affecting the communication efficiency. Therefore, the distance between the two antennas transmitting signals at the same time needs to be far enough.
[0066] For example, Figure 4As shown, antenna 401 and antenna 404 correspond to satellite communication transceiver path 410, and antenna 402 and antenna 403 correspond to satellite communication transceiver path 420, wherein antenna 401 and antenna 402 are two main antennas arranged on the top of the terminal.
[0067] When both the satellite communication transceiver path 410 and the satellite communication transceiver path 420 are in working state, the two antennas interfere with each other, resulting in the reception and transmission of radio frequency signals being affected, making it difficult to meet the communication quality index requirements. Therefore, the controller switches the main antenna in the satellite communication transceiver path 420 to antenna 403, and antenna 402 is a diversity antenna.
[0068] When the screen is held in landscape mode, causing antenna 401 and antenna 404 to be blocked, the controller controls satellite communication transceiver path 410 to be in a non-working state and controls satellite communication transceiver path 420 to be in a working state. Then the terminal selects an antenna with better performance, such as antenna 403, as the main antenna for satellite communication based on the performance parameters of antenna 402 and antenna 403.
[0069] An embodiment of the present application also provides a satellite communication chip, which is provided with a satellite communication module as described in the above embodiment.
[0070] The present application also provides a terminal, which is provided with a satellite communication chip as described in the above embodiment. Figure 5 , which shows a schematic diagram of the structure of a terminal provided by an exemplary embodiment of the present application.
[0071] The terminal 501 internally includes a satellite communication module 502. The satellite communication module 502 internally includes a controller 503, a radio frequency transceiver 504, and n satellite communication transceiver paths. In the embodiment of the present application, two satellite communication transceiver paths are used as an example for description, including a satellite communication transceiver path 505 and a satellite communication transceiver path 506.
[0072] The RF transceiver 504 is connected to each satellite communication transceiver path. The satellite communication transceiver path 505 includes a satellite communication power amplifier 507, a low noise amplifier 508, an antenna common terminal 509, an antenna common terminal 510, and a switch component 511. The RF transceiver 504 is connected to the satellite communication power amplifier 507 and the low noise amplifier 508, and the satellite communication power amplifier 507 and the low noise amplifier 508 are connected to the antenna through the switch component 511. The satellite communication power amplifier 507 is connected to the antenna 512 through the antenna common terminal 509, and the satellite communication power amplifier 507 is connected to the antenna 513 through the antenna common terminal 510. In order to reduce the insertion loss of the antenna common terminal 510, the satellite communication power amplifier 507 is located close to the antenna 512 and the antenna 513.
[0073] The satellite communication transceiver path 506 has the same structure as the satellite communication transceiver path 505. The satellite communication transceiver path 506 is connected to the antenna 514 and the antenna 515.
[0074] It should be noted that in some embodiments, the antenna for signal transmission and reception is a built-in antenna, such as a patch antenna, and is not an external antenna used in general satellite communications. Since the present application reduces the required transmission power within each satellite communication transceiver path by combining the paths, thereby reducing the insertion loss requirement of the antenna common end, the satellite communication module can share the antenna with other RF communication modules.
[0075] For example, Figure 6 As shown, the satellite communication module 601 and the cellular communication module 602 are connected to the antenna 604 via the antenna switch 603. When the antenna switch 603 is connected to the satellite communication module 601, the satellite communication module 601 uses the antenna 604 for satellite communication, and when the antenna switch 603 is connected to the cellular communication module 602, the cellular communication module 602 uses the antenna 604 for cellular communication.
[0076] In addition, since the satellite communication transmission power threshold is 36.5dBm, the corresponding required power supply current increases. In a satellite communication module with a single satellite communication transceiver channel, the satellite communication power amplifier is powered by at least two DCDC power supplies.
[0077] In the present application, the transmission power of each satellite communication transceiver path is less than the satellite communication transmission power threshold, and the voltage and current required by the satellite communication power amplifier are reduced. Therefore, each satellite communication transceiver path can be powered by only one DCDC power supply, reducing the design difficulty of the satellite communication module.

The terminal may also include one or more of the following components: a processor 701 , a memory 702 , and a satellite communication chip 703 .

Optionally, the processor 701 can be implemented in at least one hardware form of digital signal processing (Digital Signal Processing, DSP), field programmable gate array (Field-Programmable Gate Array, FPGA), and programmable logic array (Programmable Logic Array, PLA). The processor 701 can integrate one or a combination of a central processing unit (Central Processing Unit, CPU), a graphics processor (Graphics Processing Unit, GPU) and a neural network processor (Neural-network Processing Unit, NPU). Among them, the CPU mainly processes the operating system, user interface and application programs; the GPU is responsible for rendering and drawing the content required to be displayed on the touch display; the NPU is used to implement artificial intelligence (Artificial Intelligence, AI) functions.
[0080] The memory 702 may include a random access memory (RAM) or a read-only memory (ROM). Optionally, the memory 702 includes a non-transitory computer-readable storage medium.
