[0002] With the development of communication technology, the communication range of terminal equipment supporting satellite communication has been expanded and communication restrictions have been reduced, allowing users to call for help or carry out rescue operations in remote areas or harsh geographical environments.

[0003] Unlike cellular mobile network communications, the communication distance from the earth's surface to the satellite is long, and the communication signal quality is poor during satellite communications.

[0004] In related technologies, since the terminal equipment requires a large transmission power, satellite communications use independent antennas. In addition, ordinary power amplifiers have limited amplification capabilities and high insertion loss requirements for the RF front end, which restricts the antenna settings.

[0023] 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.

[0024] 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.

[0025] In order to communicate with the satellite, the terminal's transmission power needs to reach the satellite communication transmission power threshold that the satellite can receive. On the basis of the satellite communication power amplifier performing power amplification, the antenna common terminal insertion loss also needs to be reduced to a certain limit. At present, the output power of ordinary power amplifiers is difficult to meet the requirements of satellite communication, and the antenna common terminal insertion loss requirements are also difficult to meet.

[0026] In addition, the terminal equipment needs to calibrate parameters before leaving the factory so that the output power of the satellite communication power amplifier meets the satellite communication requirements. Among them, the voltage and current required by the satellite communication power amplifier are greater than those required by ordinary power amplifiers. If the calibration parameters are not set properly, the reliability risk of the power amplifier is likely to occur. For example, if the calibration voltage is set too high, the internal components of the power amplifier are likely to be burned.

[0027] The embodiment of the present application combines multiple satellite communication transceiver paths to reduce the transmission power of each satellite communication transceiver path and enhance the total transmission power of the satellite communication module. Figure 1 , which shows a schematic structural diagram of a satellite communication module provided by an exemplary embodiment of the present application.

[0028] The satellite communication module 1010 includes a controller 1020, a radio frequency transceiver 1030, and n satellite communication transceiver paths, where n is an integer greater than or equal to 2. When n=4, the module includes a satellite communication transceiver path 1041, a satellite communication transceiver path 1042, a satellite communication transceiver path 1043, and a satellite communication transceiver path 1044. The radio frequency transceiver 1030 is connected to the n satellite communication transceiver paths, respectively.

[0029] In some examples, each satellite communication transceiver path has the same path structure, so the satellite communication transceiver path 1041 is taken as an example for description.

[0030] The satellite communication transceiver path 1041 includes a satellite communication power amplifier 1051, a low noise amplifier 1052 and an antenna common terminal 1053. The satellite communication power amplifier 1051 is used to amplify the power of the transmission signal, and the low noise amplifier 1052 is used to amplify the signal of the reception signal.

[0031] The satellite communication transceiver path 1 is connected to the antenna 1061 through the antenna common terminal 1053. The satellite communication power amplifier 1051 is connected to the antenna 1061 through the antenna common terminal 1053, and the low noise amplifier 1052 is connected to the antenna 1061 through the antenna common terminal 1053. The RF transceiver 1030 is connected to the satellite communication power amplifier 1051 and the low noise amplifier 1052 respectively.

[0032] The controller 1020 is used to control the n satellite communication transceiver paths to be in working state in the first working mode, and control the radio frequency transceiver 1030 to transmit radio frequency signals to the n satellite communication transceiver paths.

[0033] When transmitting a signal, the controller 1020 first controls the RF transceiver 1030 to transmit a transmission signal to the satellite communication power amplifier 1051, and then amplifies the transmission signal through the satellite communication power amplifier 1051. The amplified transmission signal passes through the antenna common terminal 1053 and is transmitted to the antenna 1061 for transmission.

[0034] In the satellite communication module 1010, the transmission power of each satellite communication transceiver path is less than the satellite communication transmission power threshold, and the total transmission power of the n satellite communication transceiver paths is greater than or equal to the satellite communication transmission power threshold.

[0035] The satellite communication transmission power threshold is the transmission power threshold that the terminal needs to reach for signal transmission in order for the satellite to receive the terminal's transmission signal when the terminal is performing satellite communication.

[0036] In some embodiments, the total transmission power of n satellite communication transceiver paths can be calculated based on the combined gain. For example, the total transmission power of n satellite communication transceiver paths is the sum of the transmission power of each satellite communication transceiver path and the combined gain of the n satellite communication transceiver paths. Therefore, the transmission power of each satellite communication transceiver path can be less than the satellite communication transmission power threshold, thereby reducing the voltage and current required for the satellite communication power amplifier to perform power amplification, thereby avoiding damage to the satellite communication power amplifier.

[0037] When receiving a signal, after the antenna 1061 receives the RF signal, the received signal is transmitted to the low-noise amplifier 1052 through the antenna common terminal 1053. The low-noise amplifier 1052 then amplifies the received signal and transmits the amplified received signal to the RF transceiver 1030. The controller 1020 controls the RF transceiver 1030 to receive the RF signal.

[0038] It should be noted that in the solution described in the embodiment of the present application, since the output power of the satellite communication power amplifier in each satellite communication transceiver path does not need to reach the satellite communication transmission power threshold, the requirements for the performance of internal components of the satellite communication module are reduced, that is, the satellite communication module can use an ordinary power amplifier to achieve power amplification of the transmitted signal.

[0039] In summary, in the embodiment of the present application, the RF transceiver is connected to n satellite communication transceiver paths, where n is an integer greater than or equal to 2, wherein the transmission power of each satellite communication transceiver path is less than the satellite communication transmission power threshold, and the total transmission power of the n satellite communication transceiver paths is greater than or equal to the satellite communication transmission power threshold; compared with the satellite communication method using a single satellite communication transceiver path, the solution provided by the embodiment of the present application, on the one hand, increases the total transmission power of the satellite communication module, so that the total transmission power can reach the satellite communication transmission power threshold, thereby ensuring the quality of satellite communication. On the other hand, it reduces the transmission power of a single satellite communication transceiver path, thereby reducing the possibility of damage to the satellite communication power amplifier during parameter calibration, and reduces the path insertion loss requirements, thereby facilitating the setting of the front-end antenna.

[0040] In the first working mode, all n satellite communication transceiver paths are in working state. However, in some possible usage scenarios, problems such as local high temperature or excessive power consumption of the satellite communication power amplifier may occur inside the terminal. The controller can control the satellite communication module to enter the second working mode, that is, select m from the n satellite communication transceiver paths to enter the working state, to ensure the signal quality of satellite communication and avoid terminal damage.

[0041] Please refer to Figure 2 , which shows a schematic diagram of the structure of a satellite communication module provided by another exemplary embodiment of the present application, the satellite communication module 2010 includes a controller 2020, a radio frequency transceiver 2030 and n satellite communication transceiver paths. When n is 4, it includes a satellite communication transceiver path 2041, a satellite communication transceiver path 2042, a satellite communication transceiver path 2043 and a satellite communication transceiver path 2044. Among them, the satellite communication transceiver path 2041 includes a satellite communication power amplifier 2051, a low noise amplifier 2052 and an antenna common terminal 2053.

[0042] The controller 2020 is used to control m satellite communication transceiver paths to be in working state in the second working mode, and control the RF transceiver 2030 to transmit RF signals to the m satellite communication transceiver paths, where m is a positive integer less than n. Figure 2 In the example, when m is 2, the controller 2020 controls the satellite communication transceiver path 2041 and the satellite communication transceiver path 2043 to be in working state, and the satellite communication transceiver path 2042 and the satellite communication transceiver path 2044 to be in non-working state.

[0043] It should be noted that the controller 2020 may be integrated into the RF transceiver 2030 or may be independent of the RF transceiver 2030 , and the embodiment of the present application does not limit the layout of the controller.

[0044] The satellite communication power amplifier 2051 is used to amplify the power of the transmission signal, and the low noise amplifier 2052 is used to amplify the signal of the reception signal. The antenna common terminal 2053 is used to connect the antenna 2061.

[0045] In an embodiment of the present application, in the second working mode, the connection method and working process of each component in the satellite communication module are the same as those in the first working mode, so this embodiment of the present application will not be repeated here.

[0046] In a satellite communication module with a single satellite communication transceiver channel, since the amplification capacity of the satellite communication power amplifier is limited, in order to obtain a higher transmission power, the antenna common end needs to reduce the insertion loss and increase the current and voltage input to the satellite communication power amplifier. Therefore, there is a risk of damaging the satellite communication power amplifier, which increases the difficulty of the internal design of the satellite communication module.

[0047] In the first working mode and the second working mode, the terminal enhances the total transmission power by combining. In the second working mode, the transmission power of each satellite communication transceiver path is less than or equal to the satellite communication transmission power threshold, and the total transmission power of m satellite communication transceiver paths is greater than or equal to the satellite communication transmission power threshold, where m is a positive integer less than n.

[0048] Similar to the first working mode, in some embodiments, the m satellite communication transceiver paths in the second working mode are calculated based on the combining gain to obtain the total transmission power of the m satellite communication transceiver paths, that is, the sum of the transmission power of each satellite communication transceiver path and the combining gain of the m satellite communication transceiver paths.

[0049] For example, Figure 2As shown, among the four satellite communication transceiver paths, satellite communication transceiver path 2041 and satellite communication transceiver path 2043 are in working state. When the satellite communication transmission power threshold is 36.5dBm, the transmission power of satellite communication transceiver path 2042 and satellite communication transceiver path 2044 are both 33.5dBm, and the combined gain is 3dBm, so the total transmission power of the two satellite communication transceiver paths is 36.5dBm, which is equal to the satellite communication transmission power threshold.

[0050] The difference between the second working mode and the first working mode is that in the first working mode, all n satellite communication transceiver paths are in working state, while in the second working mode, since the terminal may have problems such as local overtemperature or excessive power consumption of the satellite communication power amplifier, the terminal selects m satellite communication transceiver paths from the n satellite communication transceiver paths to enter the working state to ensure the quality of satellite communication and avoid damage to the terminal.

[0051] Optionally, the terminal can select a satellite communication transceiver path according to the temperature. In some embodiments, in the second working mode, based on the terminal temperature at the corresponding position of the satellite communication power amplifier, the path state of the satellite communication transceiver path corresponding to the satellite communication power amplifier is determined, and the path state includes a working state and a non-working state.

[0052] In a possible implementation, the terminal detects the terminal temperature at the position corresponding to the satellite communication power amplifier through a temperature sensor. When the temperature reaches a temperature threshold preset inside the terminal, the controller controls the current satellite communication transceiver path to be in a non-working state; when the temperature does not reach the temperature threshold preset inside the terminal, the controller controls the current satellite communication transceiver path to be in a working state. The total number of satellite communication transceiver paths in the working state in the second working mode is m.

[0053] Optionally, the terminal may also select a satellite communication transceiver path according to the power consumption of the satellite communication power amplifier.

[0054] In one possible implementation, the terminal selects a satellite communication transceiver path based on the power consumption of the satellite communication power amplifier. When the satellite communication power amplifier is far away from the antenna and the insertion loss of the antenna common end is large, the power consumption of the satellite communication power amplifier may be large. The controller can control the path where the satellite communication power amplifier with relatively low power consumption is located to be in a working state.

[0055] Regarding the determination of n and m, in one possible implementation, the numbers n and m of satellite communication transceiver channels are preset inside the terminal. In another possible implementation, the terminal determines the values ​​of n and m according to the numbers of satellite communication transceiver channels actually available.

[0056] In addition, in the second working mode and the first working mode, the transmission power of each satellite communication transceiver path is different. In the first working mode, the n satellite communication transceiver paths all have the first transmission power, and in the second working mode, the m satellite communication transceiver paths all have the second transmission power.

[0057] Optionally, the controller may determine the transmission power of the satellite communication transceiver channel based on the satellite communication transmission power threshold and the number of satellite communication transceiver channels.

[0058] In the first working mode, a first transmission power of the satellite communication transceiver path is determined based on the satellite communication transmission power threshold and n.

[0059] In the second working mode, a second transmission power of the satellite communication transceiver path is determined based on the satellite communication transmission power threshold and m.

[0060] In a possible implementation, the terminal device first calculates the combining gain according to the number of satellite communication transceiver channels, and then determines the transmission power of each satellite communication transceiver channel according to the satellite communication transmission power threshold, wherein the transmission power of each channel is inversely proportional to the number of channels.

[0061] For example, when the satellite communication transmission power threshold is 36.5dBm and n (or m) is 3, the combined gain is calculated according to the formula 10lg (n), and it can be known that the combined gain is 10lg (3), which is about 5dBm. Therefore, according to the difference between the satellite communication transmission power threshold and the combined gain, it is determined that the first transmission power (or the second transmission power) needs to reach 31.5dBm. Similarly, when n (or m) is 2, the first transmission power (or the second transmission power) needs to reach 33.5dBm, and when n (or m) is 4, the first transmission power (or the second transmission power) needs to reach 30.5dBm.

[0062] In some embodiments, in the first working mode, all satellite communication transceiver channels are in working state, and the transmission power of each channel is the same, which is the first transmission power.

[0063] For example, Figure 3 As shown, the satellite communication module includes a satellite communication transceiver channel 301, a satellite communication transceiver channel 302, and a satellite communication transceiver channel 303. In the first working mode, n=3, the transmission power of the satellite communication transceiver channel 301 is 31.5dBm, the transmission power of the satellite communication transceiver channel 302 is 31.5dBm, and the transmission power of the satellite communication transceiver channel 303 is 31.5dBm.

[0064] In some embodiments, in the second working mode, some satellite communication transceiver channels are in working state, and the transmission powers of the channels in working state are the same, which are all the second transmission powers.

[0065] For example, Figure 4 As shown, the satellite communication module includes a satellite communication transceiver channel 401, a satellite communication transceiver channel 402, and a satellite communication transceiver channel 403. In the second working mode, n=3, m=2, the terminal temperature at the satellite communication transceiver channel 401 exceeds the temperature threshold, and the controller selects the satellite communication transceiver channel 402 and the satellite communication transceiver channel 403 to enter the working state, so the transmission power of the satellite communication transceiver channel 401 is 0dBm, the transmission power of the satellite communication transceiver channel 402 is 33.5dBm, and the transmission power of the satellite communication transceiver channel 403 is 33.5dBm.

[0066] The satellite communication transmission power threshold of the embodiment of the present application is 36.5dBm. Therefore, when there are two satellite communication transceiver channels in working state, the transmission power of the satellite communication transceiver channels is 33.5dBm; when there are three satellite communication transceiver channels in working state, the transmission power of the satellite communication transceiver channels is 31.5dBm; when there are four satellite communication transceiver channels in working state, the transmission power of the satellite communication transceiver channels is 30.5dBm.

[0067] 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.

[0068] In some embodiments, the second working mode also includes a case where there is no combining gain, that is, a case where m=1.

[0069] For example, Figure 5 As shown, the satellite communication module includes a satellite communication transceiver channel 501, a satellite communication transceiver channel 502, and a satellite communication transceiver channel 503. In the second working mode, n=3, m=1, the terminal temperature at the satellite communication transceiver channel 501 is too high, and the power consumption of the satellite communication power amplifier of the satellite communication transceiver channel 503 is too large, so the controller controls the satellite communication transceiver channel 502 to be in a working state, and the transmission power is 36.5dBm, and the satellite communication transceiver channel 501 and the satellite communication transceiver channel 503 are in a non-working state, and the transmission power is 0dBm.

[0070] It should be noted that the satellite communication transmission power thresholds required to be reached in the first working mode and the second working mode are the same. Therefore, when m is less than n, the second transmission power is greater than the first transmission power.

[0071] For example, when the satellite communication transmission power threshold is 36.5dBm and n is 3, the combined gain is calculated according to the formula 10lg(n), and it can be known that the combined gain is 10lg(3), which is about 5dBm. Therefore, according to the difference between the satellite communication transmission power threshold and the combined gain, it is determined that the first transmission power needs to reach 31.5dBm. When m is 2, 10lg(2) is about 3dBm, so the second transmission power needs to reach 33.5dBm, 33.5dBm is greater than 31.5dBm, and the second transmission power is greater than the first transmission power.

[0072] Optionally, the controller may also determine the transmission power of the satellite communication transceiver channel based on the current satellite communication quality, the satellite communication transmission power threshold, and the number of satellite communication transceiver channels.

[0073] In the first working mode, a first transmission power of the satellite communication transceiver path is determined based on the current satellite communication quality, the satellite communication transmission power threshold and n.

[0074] In the second working mode, a second transmission power of the satellite communication transceiver path is determined based on the current satellite communication quality, the satellite communication transmission power threshold and m.

[0075] In some embodiments, the controller may first determine a reference value of the transmission power of the satellite communication transceiver channel based on the satellite communication transmission power threshold and the number of satellite communication transceiver channels. Subsequently, when the satellite communication quality does not meet the communication quality index, the transmission power greater than the reference value is determined as the transmission power of the target satellite communication transceiver channel. The specific transmission power is determined based on the current satellite communication quality.

[0076] 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.

[0077] Regarding the measurement of the current satellite communication quality, in one possible implementation, the controller determines the current satellite communication quality through communication signal quality measurement indicators such as the current signal's SINR (Signal to Interference plus Noise Ratio), RSRP (Reference Signal Receiving Power) and RSSI (Received Signal Strength Indication).

[0078] In an embodiment of the present application, the terminal can select the first working mode or the second working mode for satellite communication. Since the terminal may have problems such as local overtemperature or excessive power consumption of the satellite communication power amplifier, in the second working mode, the controller can select the satellite communication transceiver path, thereby ensuring the signal quality of the satellite communication while enhancing the satellite communication transmission power and avoiding damage to the terminal.

[0079] Due to the long distance between the earth's surface and the satellite, the transmission power required for satellite communication is larger than that of cellular mobile communications, that is, it needs to reach the satellite communication transmission power threshold of 36.5dBm. Limited by the amplification capacity of the satellite communication power amplifier, the insertion loss requirement of the common end of the satellite communication module antenna of the single satellite channel transceiver channel is relatively high. For example, the insertion loss needs to be reduced to below 0.3dB. Therefore, it is inconvenient for the satellite communication module to share the antenna with other RF communication modules to avoid antenna combining and increase insertion loss.

[0080] The present application reduces the required transmission power within each satellite communication transceiver path through a combining method, thereby reducing the insertion loss requirement of the antenna common end, allowing the satellite communication module to share the antenna with other radio frequency communication modules, thereby improving the flexibility of the antenna layout in the satellite communication module.

[0081] 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.

[0082] It should be noted that, in some embodiments, the antenna for transmitting and receiving signals is a built-in antenna, such as a patch antenna.

[0083] In addition, since the satellite communication transmission power threshold is 36.5dBm, the corresponding required power supply current increases. For example, when the power supply voltage reaches 5.5V, the current needs to reach 3A, which exceeds the current range that a DCDC (Direct Current) power supply can provide. Therefore, when the transmission power of a single satellite communication transceiver channel reaches the satellite communication transmission power threshold, 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.

[0084] In the embodiment of 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.

[0085] 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.

[0086] The present application also provides a terminal, which is provided with a satellite communication chip as described in the above embodiment. Figure 7 , which shows a schematic diagram of the structure of a terminal provided by an exemplary embodiment of the present application.

[0087] The terminal 701 includes a satellite communication module 702. The satellite communication module 702 includes a controller 703, a radio frequency transceiver 704, and n satellite communication transceiver paths. In the embodiment of the present application, three satellite communication transceiver paths are used as an example for description, including a satellite communication transceiver path 705, a satellite communication transceiver path 706, and a satellite communication transceiver path 707.

[0088] The RF transceiver 704 is connected to each satellite communication transceiver path. Among them, the satellite communication transceiver path 705 includes a satellite communication power amplifier 708, a low noise amplifier 709 and an antenna common terminal 710. The RF transceiver 704 is connected to the satellite communication power amplifier 708 and the low noise amplifier 709, and the path where the satellite communication power amplifier 708 is located and the path where the low noise amplifier 709 is located intersect at the antenna common terminal 710. The antenna common terminal 710 is connected to the antenna 711. The internal structure of the satellite communication transceiver path 706 and the satellite communication transceiver path 707 is the same as that of the satellite communication transceiver path 705. The satellite communication transceiver path 706 is connected to the antenna 712. The satellite communication transceiver path 707 is connected to the antenna 713. Among them, the antenna 711, the antenna 712 and the antenna 713 are distributed in the middle frame of the terminal 701. In order to reduce the insertion loss of the antenna common terminal 710, the satellite communication power amplifier 708 is located close to the antenna 711.
