[0002] In related technologies, terminals are limited by the multiple-input multiple-output technology of a single antenna. Therefore, when connecting to the next non-terrestrial network device, such as connecting to a satellite, they need to disconnect from the current non-terrestrial network device. This makes it impossible to achieve fast and uninterrupted seamless switching of non-terrestrial network communication. Summary of the Invention

[0036] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0037] To better understand the technical solution of this application, the following explanations are provided for several terms involved in this application:

[0038] Non-terrestrial network equipment includes airborne or spaceborne vehicles. Spaceborne vehicles may include, but are not limited to, low Earth Orbit (LEO) satellites, medium Earth Orbit (MEO) satellites, geostationary Earth Orbit (GEO) satellites, and highly elliptical orbit (HEO) satellites. Airborne vehicles include, but are not limited to, unmanned aircraft systems (UAS) and high-altitude platform systems (HAPS).

[0039] Non-Terrestrial Networks (NTN): Networks or network segments that use airborne or spaceborne vehicles for transmission.

[0040] Low Earth Orbit (LEO) satellites: satellites whose altitude above the Earth's surface is below the first altitude threshold.

[0041] Medium Earth Orbit (MEO) satellites: satellites whose altitude above the ground exceeds a first altitude threshold but is below a second higher altitude threshold.

[0042] High-orbit satellites: Satellites whose altitude above the ground exceeds the second altitude threshold.

[0043] The following uses a satellite as an example of a non-terrestrial network device to illustrate one of the application scenarios involved in the embodiments of this application:

[0044] like Figure 1As shown, in a terrestrial mobile communication system, base stations are stationary, while users are relatively mobile. When a user moves out of the coverage area of ​​a base station, they will connect to a nearby base station to ensure uninterrupted communication. Furthermore, handover in terrestrial mobile networks is relatively slow. In terrestrial mobile communication systems, co-frequency networking can be used to increase spectrum utilization, and soft frequency reuse can be employed to improve throughput in edge areas.

[0045] In satellite mobile communication systems, satellite communication beams are typically formed into a narrow beam in space based on communication requirements and antenna performance to achieve precise signal coverage and transmission. However, this requires ground terminals to accurately locate the source satellite transmitting the beam. If the ground terminal fails to accurately align with the beam, it may be subject to interference from signals transmitted by other beams. Furthermore, there is a phase gap between the orbital planes of adjacent satellites; for example, such as... Figure 2 As shown, the phase interval between orbits 1, 2, and 3 is 20°, meaning the phase interval between adjacent satellites is 20°. Figure 3 The diagram shown illustrates the beam coverage of adjacent satellites in the same orbit and satellites in adjacent orbits. This is for ease of explanation. Figure 3 In China, orbits are marked with equally spaced straight lines, and satellites in different orbits are also on the same straight line. Therefore, in order to avoid collisions between satellites and overcome changes in the coverage beam range and mutual interference between beams, continuous and strict phase-keeping control is required, which increases the difficulty of handover between terminals and satellites.

[0046] Furthermore, in satellite mobile communication systems, low-Earth orbit (LEO) satellite mobile networks involve high-frequency handover, while handover in terrestrial networks is characterized by low frequency. Although event-based handover methods are highly efficient in terrestrial mobile networks, they are not suitable for LEO satellite mobile networks. The main reasons are as follows:

[0047] First, low-Earth orbit (LEO) satellite mobile networks switch very frequently, and the communication latency between LEO satellites and ground terminals is much higher than that of terrestrial networks, which may cause service interruptions during switching.

[0048] Second, in low-Earth orbit satellite mobile networks, due to the limitations of multi-input multi-output (MIMO) antenna technology, terminal configurations cannot support simultaneous access to multiple satellites, meaning that event-driven handover management cannot be implemented.

[0049] Based on the aforementioned illustrative application scenario, embodiments of this application provide a terminal device, a non-terrestrial network communication method, an electronic device, a readable storage medium, and a computer program product. The technical solution of this application will now be described in detail through specific embodiments.

[0050] Figure 4An exemplary embodiment of this application illustrates a terminal device, comprising: a first antenna plane 410 having a first antenna 411, the first antenna plane 410 being parallel to a horizontal plane; a second antenna plane 420 having a second antenna 421, the second antenna plane 420 being disposed below a first side of the first antenna plane 410 and forming a target angle with the first antenna plane, wherein the target angle is greater than 90° and less than 180°; and a third antenna plane 430 having a third antenna 431, the third antenna plane 430 being disposed below a second side of the first antenna plane 410 and forming the target angle with the first antenna plane.

[0051] The top view of the terminal device is as follows: Figure 5 As shown, the side view is as follows Figure 6 As shown.

[0052] Understandably, this application adds two elevation antennas, namely a second antenna and a third antenna, to the first antenna. The planes of the second and third antennas form a target angle with the plane of the first antenna. This target angle setting helps to detect the next incoming non-terrestrial network device in advance, without waiting for the non-terrestrial network device to reach the top of the terminal for alignment. In other words, this target angle setting can effectively expand the detection range and improve the flexibility of matching antenna polarization with the polarization of non-terrestrial network devices.

[0053] In this embodiment, three antennas can solve the problem of network dropout during non-terrestrial network communication and the problem of shortened call time window caused by the antenna not being able to be aligned with the non-terrestrial network device in time. This enables fast and uninterrupted seamless switching in non-terrestrial network communication. Furthermore, the simultaneous use of multiple antennas for detection effectively improves detection efficiency.

[0054] For example, the following illustrations illustrate the switching between three antennas for the following four types of non-terrestrial network devices:

[0055] (1) For non-terrestrial network devices without beam coverage, for example, such as Figure 7As shown, assuming the non-terrestrial network device moves in the first direction, it first enters the detection range of the third antenna at the first moment, then the detection range of the first antenna at the second moment, and finally the detection range of the second antenna at the third moment. By connecting all three antennas, the communication time between the terminal device and the non-terrestrial network device is effectively extended. Similarly, in another direction of movement, the non-terrestrial network device can first enter the detection range of the second antenna, then the first antenna, and finally the third antenna. In other words, the terminal device provided in this application is not restricted by direction. Therefore, by sequentially connecting the three antennas, the communication time with the non-terrestrial network device can be effectively extended.

[0056] It should be noted that the first antenna plane, the second antenna plane, and the third antenna plane are only used for placing the antenna. Therefore, the first antenna plane, the second antenna plane, and the third antenna plane will not be labeled in the schematic diagram. Instead, the first antenna, the second antenna, and the third antenna will be used for illustrative purposes.

[0057] (2) For adjacent, consecutive non-terrestrial network devices without beam coverage, it is assumed that the movement direction of the non-terrestrial network device is also the first movement direction. For details on the first movement direction, please refer to [link to relevant documentation]. Figure 7 This will not be elaborated further. For example, as follows: Figure 8 As shown, at the first moment, non-terrestrial network device 1 has entered the detection range of the third antenna, while non-terrestrial network device 2 has not. At this time, the third antenna can detect the non-terrestrial network signal sent by non-terrestrial network device 1, but cannot detect the non-terrestrial network signal sent by non-terrestrial network device 2. At the second moment, non-terrestrial network device 1 has entered the detection range of the first antenna, and non-terrestrial network device 2 has entered the detection range of the third antenna. At this time, the first antenna can detect the non-terrestrial network signal sent by non-terrestrial network device 1, and the third antenna can detect the non-terrestrial network signal sent by non-terrestrial network device 2. At the third moment, non-terrestrial network device 1 has passed the detection range of the second antenna, and non-terrestrial network device 2 has entered the detection range of the second antenna. At this time, the second antenna can detect the non-terrestrial network signal sent by non-terrestrial network device 2, but cannot detect the non-terrestrial network signal sent by non-terrestrial network device 1. It should be noted that the movement directions of non-terrestrial network device 1 and non-terrestrial network device 2 are the same. Therefore, using multiple antennas simultaneously for detection effectively improves detection efficiency.

[0058] In one embodiment, the non-terrestrial network device 1 and the non-terrestrial network device 2 can simultaneously enter the detection range of the third antenna and / or the detection range of the first antenna and / or the detection range of the second antenna.

[0059] (3) For non-terrestrial network devices with beam coverage, for example, such as Figure 9 As shown, assuming the non-terrestrial network device moves in the same direction as the first direction, then at the first moment, the first antenna, the second antenna, and the third antenna all fail to detect the network signal transmitted by the non-terrestrial network device 1. At the second moment, the non-terrestrial network device 1 enters the detection range of the first and third antennas but cannot enter the detection range of the second antenna. At this time, the second antenna is parallel to one beam edge of the non-terrestrial network device 1, and will either fail to detect the network signal or detect a very weak network signal. At the third moment, the non-terrestrial network device 1 enters the detection range of the first, second, and third antennas, at which point all three antennas can detect the non-terrestrial network signal. The network signal of device 1 is detected at the following time: At the fourth moment, the first and second antennas can detect the network signal transmitted by non-terrestrial network device 1. At this time, the third antenna is parallel to the other beam edge of non-terrestrial network device 1 and will not be able to receive the network signal or the detected network signal strength will be very weak. At the fifth moment, non-terrestrial network device 1 leaves the detection range of the first and third antennas. At this time, only the second antenna can detect the network signal transmitted by non-terrestrial network device 1. At the sixth moment, non-terrestrial network device 1 leaves the detection range of the first, second, and third antennas. At this time, none of the first, second, and third antennas can detect the network signal transmitted by non-terrestrial network device 1. Therefore, using multiple antennas simultaneously for detection effectively improves detection efficiency.

[0060] (4) For adjacent, consecutive non-terrestrial network devices with beam coverage, for example, such as Figure 10As shown, assuming the non-terrestrial network device moves in the same direction as the first direction, then at the first moment, the first antenna, the second antenna, and the third antenna all fail to detect the network signals transmitted by non-terrestrial network device 1 and non-terrestrial network device 2. At the second moment, non-terrestrial network device 1 enters the detection range of the first and third antennas but cannot enter the detection range of the second antenna. At this time, the second antenna is parallel to one beam edge of non-terrestrial network device 1, and will not be able to receive the network signal from non-terrestrial network device 1 or the received network signal will be very weak. At the third moment, non-terrestrial network device 1 enters the detection range of the first and second antennas. At the fourth moment, non-terrestrial network device 1 and non-terrestrial network device 2 simultaneously enter the detection range of the third antenna. This means that the beam overlap area of ​​non-terrestrial network device 1 and non-terrestrial network device 2 intersects with the detection range of the third antenna. The third antenna can simultaneously detect the network signals transmitted by both non-terrestrial network device 1 and non-terrestrial network device 2. This beam overlap area is the overlapping portion of the beam coverage range of non-terrestrial network device 1 and non-terrestrial network device 2. Meanwhile, the first antenna... At the fifth moment, in the beam overlap region, the first, second, and third antennas can all detect the network signals transmitted by non-terrestrial network device 1 and non-terrestrial network device 2. At the sixth moment, in the beam overlap region, the first, second, and third antennas can all detect the network signals transmitted by non-terrestrial network device 2, and the first and second antennas can detect the network signals transmitted by non-terrestrial network device 1. At this time, the third antenna is parallel to one beam edge of non-terrestrial network device 1 and will be unable to receive the network signal of non-terrestrial network device 1 or... The received network signal strength is very weak. At the seventh moment, non-terrestrial network device 2 enters the detection range of the first, second, and third antennas. At this time, all three antennas can detect the network signal of non-terrestrial network device 2, while the second antenna can also detect the network signal transmitted by non-terrestrial network device 1 in the beam overlap area. At the eighth moment, non-terrestrial network device 2 enters the detection range of the first, second, and third antennas. At this time, all three antennas can detect the network signal of non-terrestrial network device 2, but cannot detect the network signal of non-terrestrial network device 1. In this example, the communication continuity and communication time are increased by using multiple antennas for cyclic smooth access detection.

[0061] It should be noted that this example only uses non-terrestrial network device 1 and non-terrestrial network device 2 for illustrative purposes. However, the same track may include multiple adjacent and consecutive non-terrestrial network devices with beam coverage. The switching principle between their antennas is different from the switching principle between non-terrestrial network devices. Figure 10 The same applies, so I won't elaborate further.

[0062] Here, "adjacent and continuous" refers to devices belonging to the same orbit, located adjacently, and having a beam overlap area. Regarding the beam overlap area, it can be understood that for adjacent and continuous non-terrestrial network devices with beam coverage, if the distance between two adjacent and continuous non-terrestrial network devices is greater than 0 and less than or equal to the sum of the first radiation radius and the second radiation radius, the beam coverage areas of the two adjacent and continuous non-terrestrial network devices overlap. This overlapping part is the beam overlap area. The first radiation radius is the radiation radius of non-terrestrial network device 1, and the second radiation radius is the radiation radius of non-terrestrial network device 2. For example, as shown... Figure 11a As shown in the figure, the shaded area represents the beam overlap region. The distance between non-terrestrial network device 1 and non-terrestrial network device 2 is d, where d is less than (r1 + r2). Furthermore, the extent of this beam overlap region is related to the antenna radiation angle or beam radius of these two non-terrestrial network devices. In adjacent, consecutive non-terrestrial network devices with beam coverage, if each device has the same antenna radiation angle or beam radius, then the beam coverage area of ​​any two adjacent non-terrestrial network devices is the same. For example, as shown... Figure 11bAs shown, non-terrestrial network device 0, non-terrestrial network device 1, and non-terrestrial network device 2 represent three non-terrestrial network devices adjacent to each other on the same track. Beam 0, beam 1, and beam 2 represent the signal beams of the three non-terrestrial network devices, respectively. h0, h1, and h2 represent the track heights of the three non-terrestrial network devices, respectively. Their track heights are the same on the same track surface, i.e., h0 = h1 = h2. d is the distance between any two non-terrestrial network devices. The following explanation uses non-terrestrial network device 0 and non-terrestrial network device 1 as examples. r0 and r1 are the radiation radii of non-terrestrial network device 0 and non-terrestrial network device 1, respectively. s represents the distance between the bottom edges of the beam overlap areas of the two non-terrestrial network devices. O0 and O1 represent the beam centers of non-terrestrial network device 0 and non-terrestrial network device 1, respectively. b0 and b1 represent the beam edges, respectively. a is the beam radiation angle. Where r0 = h0·tan(a), r1 = h1·tan(a), and r0 = r1, s = r0 - (O0, b1), s = r1 - (O1, b0); therefore, (O0, b1) = (O1, b0), meaning the beam overlap area is exactly the same. In other words, at the same orbital altitude, adjacent, consecutive non-terrestrial network devices with beam coverage will have the same beam overlap area if the antenna radiation angle or beam radiation radius is the same. In one embodiment, when the antenna radiation angle or beam radiation radius is different, the beam overlap area may be different, such as... Figure 11c As shown, with antenna radiation angles a>b>c and beam radiation radii r0>r1>r2, and assuming equal distances between non-terrestrial network devices (d1=d2), beam overlap region 1 is larger than beam overlap region 2; as Figure 11d As shown, with antenna radiation angles a>b>c and beam radius r0>r1>r2, and assuming equal distances between non-terrestrial network devices (d1>d2), beam overlap region 1 is larger than beam overlap region 2. In other words, at the same orbital altitude, the size of the beam overlap region is related to the antenna radiation angles or beam radii of the corresponding two non-terrestrial network devices, as well as the distance between them. Furthermore, it should be noted that regardless of whether the antenna radiation angles or beam radii of the non-terrestrial network devices in the same orbit are the same, a beam overlap region exists as long as the distance between any two adjacent non-terrestrial network devices is less than or equal to the sum of their beam radii.

[0063] In the beam overlap area, the terminal device provided in this application can detect network signals transmitted by two non-terrestrial network devices associated with the beam overlap area. For example... Figure 12aAs shown, this is an enlarged schematic diagram of the beam overlap region. At the first moment, the third antenna can simultaneously detect network signals transmitted by two non-terrestrial network devices; at the second moment, the third antenna and the first antenna can simultaneously detect network signals transmitted by two non-terrestrial network devices; at the third moment, the first antenna, the second antenna, and the third antenna can simultaneously detect network signals transmitted by two non-terrestrial network devices.

[0064] Furthermore, while the antenna radiation angles of non-terrestrial network devices on the same track are identical and fixed, the overlapping areas between adjacent devices vary due to differences in ground elevation. However, for adjacent non-terrestrial network devices reaching the same location, the overlapping area remains constant. Figure 12b As shown, surface 1 and surface 2 represent ground elevations at different altitudes.

[0065] In one implementation, such as Figure 13 As shown, the terminal device may further include: a signal processing module 440, which is used to determine a main communication antenna and a main communication device based on the signal strength of at least one non-terrestrial network signal detected by the first antenna 411, the second antenna 421 and the third antenna 431, wherein the main communication antenna is used to communicate with the main communication device.

[0066] It is understandable that at least one non-terrestrial network signal is transmitted by at least one non-terrestrial network device. Each antenna may not detect, or may detect one or more non-terrestrial network signals. Therefore, in non-terrestrial network communication, as long as the first antenna, the second antenna, and the third antenna detect at least one non-terrestrial network signal, the main communication antenna is determined from the first antenna, the second antenna, and the third antenna, based on the signal strength of the at least one non-terrestrial network signal. The main communication device is also determined from the at least one non-terrestrial network device that transmitted the at least one non-terrestrial network signal. Non-terrestrial network communication is then achieved based on the main communication antenna and the main communication device. In other words, as long as non-terrestrial network signals can be detected, the terminal can be controlled to switch uninterruptedly between different adjacent non-terrestrial network devices, maintaining communication stability.

[0067] For example, for non-terrestrial network devices with beam coverage, such as Figure 14 As shown:

[0068] At the first moment, when the non-terrestrial network signal sent by the non-terrestrial network device does not enter the antenna detection range of the terminal device, the terminal device enters the detection waiting state;

[0069] At the second moment, when the non-terrestrial network device enters the detection range of the terminal antenna, that is, on the third day, the non-terrestrial network signal is detected first and communication is established with the non-terrestrial network device, and the first and second antennas enter the standby state.

[0070] At the third moment, when the third antenna and the first antenna detect non-terrestrial network signals, and the signal strength detected by the first antenna is less than the signal strength detected by the third antenna, the third antenna, as the main communication antenna, continues to maintain communication with the non-terrestrial network device. At the same time, the first antenna enters standby or communication hold state. The communication hold state means that it has registered with the non-terrestrial network device but does not exchange services with the non-terrestrial network device.

[0071] At the third moment, when the third antenna and the first antenna detect non-terrestrial network signals, and the signal strength detected by the first antenna is greater than the signal strength detected by the third antenna, the first antenna, as the main communication antenna, continues to maintain communication with the non-terrestrial network equipment, while the second antenna and the third antenna enter standby or communication hold-up state.

[0072] At the fourth moment, when the first antenna, the second antenna, and the third antenna all detect network signals sent by non-terrestrial network devices, the antenna with the strongest signal strength becomes the main communication antenna, and the other antennas enter standby or communication hold-up state.

[0073] At the fifth moment, when the first antenna and the second antenna detect non-terrestrial network signals, and the signal strength detected by the second antenna is less than the signal strength detected by the first antenna, the first antenna, as the main communication antenna, continues to maintain communication with the non-terrestrial network equipment, while the third antenna and the second antenna enter standby or communication hold-up state.

[0074] At the fifth moment, when the first antenna and the second antenna detect non-terrestrial network signals, and the signal strength detected by the second antenna is greater than that detected by the first antenna, the second antenna, as the main communication antenna, continues to maintain communication between the second antenna and the non-terrestrial network equipment, while the first antenna and the third antenna enter standby or communication hold-up state.

[0075] At the sixth moment, only the second antenna detected non-terrestrial network signals, while the third and first antennas entered standby mode.

[0076] At the seventh moment, when the first antenna, the second antenna, and the third antenna all fail to detect the signal of the non-terrestrial network device, it indicates that the current non-terrestrial network device has flown past the detection range of the terminal device, and no other non-terrestrial network device will enter the detection range. All services will be disconnected, and the device will enter standby mode to wait for the next non-terrestrial network device to enter the detection range.

[0077] For example, when there is a beam overlap region between two adjacent non-terrestrial network devices in the same orbit, wherein the signal strengths of the non-terrestrial network device 1 detected by the first antenna, the second antenna, and the third antenna are set to Q1, Q2, Q3, Q4, Q5, Q6, Q7, Q8, Q9, Q1, Q2, Q3, Q4 ... in,1 Q in,2 Q in,3 The signal strengths of the non-terrestrial network device 2 detected by the first antenna, the second antenna, and the third antenna are Q, respectively. next,1 Q next,2 Q next,3 Therefore, the switching control method for the three antennas among non-ground equipment is as follows:

[0078] If the current terminal device has already established communication with non-terrestrial network device 1, and the third antenna has not detected a signal sent by the next non-terrestrial network device, then there is currently only one on-orbit non-terrestrial network device 1, and Q... next,1 Q next,2 Q next,3 =0, therefore, it can be referenced Figure 14 The diagram illustrates a communication method between non-terrestrial network devices without beam coverage.

[0079] In the first moment, if Q in,3 in,1 Q in,2 And Q next,3 =0, then the first antenna is the current communication antenna, i.e., the main communication antenna, the second antenna and the third antenna enter the waiting state, and the next non-terrestrial network device does not enter the detection range of the third antenna.

[0080] At the second moment, if Q in,3 in,1 Q in,2 And Q next,3 If Q > 0, then the first antenna is the primary communication antenna, and the third antenna has detected the arrival of the next non-terrestrial network device, namely non-terrestrial network device 2, and has established communication with non-terrestrial network device 2, entering the communication waiting phase. next,3 in,1 At that time, the first antenna continues to serve as the primary communication antenna, the third antenna establishes communication with the non-terrestrial network device 2 and enters the communication waiting phase, and the second antenna enters the waiting state; when Q next,3 Q in,1 When the signal is received, the third antenna is switched to communicate with the non-terrestrial network device 2, while the first and second antennas are disconnected from the non-terrestrial network device 1 and enter a waiting state.

[0081] At the third moment, if Q in,3 in,1 in,2 And Q next,3 ​​​​​=0, then the second antenna is the main communication antenna, the first antenna and the third antenna enter the waiting state, and the non-terrestrial network device 2 does not enter the detection range of the third antenna.

[0082] At the fourth moment, if Q in,3 in,1 in,2 And Q next,3 If Q > 0, then the second antenna is the main communication antenna, and the third antenna has detected the arrival of non-terrestrial network device 2 and established communication with it. next,3 Q in,2 When the signal is received, the third antenna is switched to communicate with the non-terrestrial network device 2, while the first and second antennas enter a standby state.

[0083] It should be noted that, due to the high cost of communication handover between non-terrestrial networks, communication handover between non-terrestrial networks can be achieved through terminal devices.

[0084] In this implementation, the trajectory of non-terrestrial network devices is determined by the signal strength of the received non-terrestrial network signals, thereby detecting non-terrestrial network devices within the current communication range and the next non-terrestrial network device to enter the communication range. At the same time, since signal strength can be used to evaluate communication quality, determining the main communication antenna and main communication device based on signal strength can ensure communication quality and reduce the possibility of communication interruption.

[0085] In one implementation, the included angle of the target is the sum of 90° and the antenna radiation angle of the non-terrestrial network device, wherein the antenna radiation angle is less than 90°.

[0086] It is understandable that for non-terrestrial network equipment with beam coverage and the terminal's first, second, and third antennas, the directivity of the beam determines the effective communication angular range. The terminal equipment's antenna beam needs to be aligned with the direction of the non-terrestrial network equipment to achieve optimal reception or transmission. Therefore, the elevation angles of the second and third antennas are typically correlated with the radiation angles of the non-terrestrial network equipment's antennas to ensure communication reliability and efficiency. For example, as... Figure 15 As shown, assuming the antenna radiation angle is 'a', the target angle is (90°+a), and the elevation angles of the second and third antennas are (90°-a). In one embodiment, since the low-orbit satellite is 500km to 1200km above the Earth's surface, the antenna radiation angle 'a' can be between 40° and 60°.

[0087] In one implementation, the first antenna, the second antenna, and the third antenna are all circularly polarized antennas.

[0088] ​​Understandably, circularly polarized antennas can receive and radiate waves of any polarization, including linear and circular polarization. This means that when communicating with satellites with different polarization characteristics, circularly polarized antennas can more easily achieve polarization matching without frequent adjustments to the antenna's polarization state, simplifying the alignment process with non-terrestrial network equipment compared to linearly polarized antennas. Furthermore, circularly polarized antennas are resistant to multipath interference. Multipath interference is a problem in communication with non-terrestrial network equipment, leading to signal attenuation and degraded communication quality. The resistance to multipath interference by circularly polarized antennas helps reduce its impact, improving communication stability and reliability.

[0089] In one embodiment, such as Figure 16 As shown, the terminal device may also include a baseband control module 450, an antenna switching module 460, and a phase shifting processing module 470. The baseband control module 450 is used to perform antenna switching and / or non-terrestrial network device switching according to the signal processing module 440 determining the main communication antenna and main communication equipment. The antenna switching module 460 is used to receive instructions sent by the baseband control module 450 and execute antenna switching and / or non-terrestrial network device switching. The phase shifting processing module 470 is used to perform phase shifting processing on the non-terrestrial network signal after antenna switching and / or non-terrestrial network device switching. That is, since the phase difference between adjacent non-terrestrial network devices may cause communication interruption, the phase shifting processing module is needed to perform phase shifting processing on the non-terrestrial network signal.

[0090] In one embodiment, such as Figure 17 As shown, the terminal device may further include a radio frequency front-end module 480 and a radio frequency module 490. The radio frequency front-end module 480 includes a first radio frequency front-end 481 corresponding to the first antenna 411, a second radio frequency front-end 482 corresponding to the second antenna 421, and a third radio frequency front-end 483 corresponding to the third antenna 423. The first end of the radio frequency module 490 is connected to the antenna switching module 460, and the second end of the radio frequency module 490 is connected to the phase shifting processing module 470.

[0091] Figure 18 This illustration shows a flowchart of a non-terrestrial network communication method provided in an exemplary embodiment of this application. The method can be implemented by... Figure 4 The method, executed by the terminal device shown, may include the following steps:

[0092] S1810: Acquire the signal strength of non-terrestrial network signals detected by the first antenna, the second antenna, and the third antenna.

[0093] In this case, each antenna may fail to detect or may not detect at least one non-terrestrial network signal.

[0094] For example, suppose the third antenna detects non-terrestrial network signals transmitted by non-terrestrial network device 1 and non-terrestrial network device 2, the first antenna detects the non-terrestrial network signal transmitted by non-terrestrial network device 1, and the second antenna does not detect any non-terrestrial network signals. Then, the signal strength of the non-terrestrial network signal transmitted by non-terrestrial network device 1 detected by the third antenna can be obtained as Q. 1,3 The signal strength of the network signal transmitted by the non-terrestrial network device 2 is Q. 2,3 The first antenna detected a network signal strength of Q from the non-terrestrial network device 1. 2,3 .

[0095] S1820: Determine that the main communication antenna is the antenna corresponding to the largest of the said signal strengths.

[0096] It is understood that in non-terrestrial network communication, as long as at least one of the first antenna, the second antenna, and the third antenna detects at least one non-terrestrial network signal, the main communication antenna is determined from the first antenna, the second antenna, and the third antenna based on the signal strength of the at least one non-terrestrial network signal. The main communication antenna is the antenna corresponding to the largest signal strength among at least one of the said signal strengths.

[0097] Continuing to refer to the example in S1810, in Q 1,3 Q 2,3 Q 2,3 In this case, the main communication antenna is determined to be the third antenna; in Q 1,3 2,3 Q 2,3 In this case, the main communication antenna is determined to be the third antenna; in Q 1,3 2,3 2,3 In this case, the main communication antenna is determined to be the first antenna.

[0098] S1830: Communicate with the main communication device through the main communication antenna.

[0099] The main communication device is the non-terrestrial network device corresponding to the maximum signal strength detected by the main communication antenna.

[0100] In other words, the main communication device is the non-terrestrial network device with the strongest signal strength among those that transmit at least one non-terrestrial network signal. Continuing with the example in S1820, in Q... 1,3 Q 2,3 Q 2,3 In this case, the main communication device is determined to be a non-terrestrial network device 1; in Q 1,3 2,3 Q​​​​2,3 In this case, the main communication device is determined to be a non-terrestrial network device 1; in Q 1,3 2,3 2,3 In this case, the main communication device is determined to be a non-terrestrial network device 2.

[0101] In this embodiment, the signal strength of the non-terrestrial network signal detected by the first antenna, the second antenna, and the third antenna is obtained. Then, the main communication antenna is determined to be the antenna corresponding to the largest signal strength among at least one signal strength. Finally, communication is established with the main communication device through the main communication antenna. The main communication device is the non-terrestrial network device corresponding to the largest signal strength detected by the main communication antenna, which expands the signal detection range. The communication connection is established with the corresponding non-terrestrial network device based on the antenna of the non-terrestrial network signal with the largest detected signal strength, which improves the flexibility of communication between the terminal device and the non-terrestrial network device and ensures the communication quality between the terminal device and the non-terrestrial network device.

[0102] In one implementation, after communicating with the main communication device via the main communication antenna, the method further includes: acquiring the signal strength of the non-terrestrial network signal detected by the first antenna, the second antenna, and the third antenna; determining that the first target antenna is the antenna corresponding to the largest signal strength among at least one of the signal strengths; re-determining the main communication antenna and / or the main communication device based on the first target antenna and the first target device, wherein the first target device is the non-terrestrial network device corresponding to the largest signal strength detected by the first target antenna; and communicating with the main communication device via the main communication antenna.

[0103] It is understood that after communication with the main communication device via the main communication antenna, the main communication antenna and / or the main communication device may be changed due to the following circumstances:

[0104] (1) When non-terrestrial network devices move at high speed around the earth, their position relative to the ground changes constantly. As the non-terrestrial network devices move, the terminal device will lose its connection with the main communication device and will need to switch to another non-terrestrial network device to maintain communication.

[0105] (2) In a non-terrestrial network communication system, there are multiple non-terrestrial network devices. In order to optimize bandwidth allocation and load balancing, it is necessary to switch communication between different non-terrestrial network devices. In addition, if a non-terrestrial network device fails or is under maintenance, it is necessary to switch to another non-terrestrial network device to maintain communication and ensure service continuity.

[0106] ​​(3) As the terminal device moves, it may enter the beam coverage area of ​​a new non-terrestrial network device. At this time, it is necessary to switch to the non-terrestrial network device to maintain communication.

[0107] Meanwhile, during the handover of non-terrestrial network equipment, there may be a switch of the main communication antenna. Since the signal strength of the non-terrestrial network signal detected by each antenna is different, it may be necessary to redetermine the main communication antenna from the first antenna, the second antenna, and the third antenna.

[0108] In this implementation, after communicating with the main communication device through the main communication antenna, the main communication antenna and / or the main communication device are redefined, and then communication is carried out based on the redefined main communication antenna and the main communication device, so that the terminal device can always connect to the non-terrestrial network device with the strongest signal, thereby improving communication quality and ensuring user experience.

[0109] In another implementation, the step of re-determining the main communication antenna and / or the main communication device based on the first target antenna and the first target device includes: re-determining the main communication antenna as the first target antenna and re-determining the main communication device as the first target device when the main communication antenna is not the first target antenna and the main communication device is not the first target device; or re-determining the main communication antenna as the first target antenna when the main communication antenna is not the first target antenna and the main communication device is the first target device; or re-determining the main communication device as the first target device when the main communication antenna is the first target antenna and the main communication device is not the first target device.

[0110] It is understandable that the first target antenna is the antenna corresponding to the largest signal strength among at least one signal strength, and the first target device is the non-terrestrial network device corresponding to the largest signal strength detected by the first target antenna. Therefore, it is necessary to compare the first target antenna with the main communication antenna and the first target device with the main communication device. If the main communication antenna is not the first target antenna, the main communication antenna is re-determined. If the main communication device is not the first target device, the main communication device is re-determined. This can provide stable, reliable and efficient communication services.

[0111] In another implementation, determining the first target antenna as the antenna corresponding to the largest of at least one of the signal strengths includes: determining the first target antenna as the first antenna when the first antenna detects a signal strength greater than the signal strengths detected by the second antenna and the third antenna; or determining the first target antenna as the second antenna when the second antenna detects a signal strength greater than the signal strengths detected by the first antenna and the third antenna; or determining the first target antenna as the third antenna when the third antenna detects a signal strength greater than the signal strengths detected by the first antenna and the second antenna.

[0112] It is understandable that the three antennas may be within the communication range simultaneously, and each antenna has a different angle. The signal strength detected from the same non-terrestrial network device may be different, and the signal strength detected from different non-terrestrial network devices may also be different. Therefore, if the first antenna, the second antenna, and the third antenna all detect at least one non-terrestrial network signal, then the first target antenna is the antenna with the highest detected signal strength among the three antennas. In this way, by selecting the antenna with the highest signal strength as the first target antenna, better communication quality can be ensured and the possibility of communication interruption can be reduced.

[0113] In one implementation, after communicating with the main communication device via the main communication antenna, the method further includes: acquiring the signal strength of the non-terrestrial network signal transmitted by the main communication device detected by the first antenna, the second antenna, and the third antenna respectively; determining the second target antenna as the antenna whose detected signal strength is greater than a first threshold; and communicating with the main communication device via the main communication antenna and the second target antenna.

[0114] In another implementation, determining that the second target antenna is an antenna whose detected signal strength is greater than a first threshold includes: determining that the second target antenna includes the first antenna when the first antenna detects a signal strength greater than the first threshold and the main communication antenna is not the first antenna; or determining that the second target antenna includes the second antenna when the second antenna detects a signal strength greater than the first threshold and the main communication antenna is not the second antenna; or determining that the second target antenna includes the third antenna when the third antenna detects a signal strength greater than the first threshold and the main communication antenna is not the third antenna.

[0115] Understandably, at the first moment, the main communication antenna receives the strongest network signal from the main communication device. Therefore, communication occurs through the main communication antenna. At the second moment, the terminal device receives a signal strength from the second target antenna that exceeds a first threshold, indicating that the first target antenna may be in a better receiving location or environment, providing a higher quality signal. Therefore, while the main communication antenna is communicating with the main communication device, communication between the second target antenna and the main communication device can be increased simultaneously. This allows multiple antennas to establish satellite communication simultaneously, enabling the terminal device to maximize communication efficiency based on real-time signal strength changes.

[0116] In one embodiment, in another implementation, during communication, if the signal strength detected by one of the antennas is less than a first threshold, the communication of that antenna is disconnected and it enters a standby state. That is, the first threshold is set to ensure communication quality; therefore, at any time, if the signal strength detected by any antenna is less than the first threshold, it indicates that the antenna cannot provide reliable communication service, and thus the communication connection between that antenna and the main communication device needs to be disconnected.

[0117] In one implementation, after communicating with the main communication device via the main communication antenna, the method further includes: acquiring the signal strength of a non-terrestrial network signal transmitted by a second target device detected by a third target antenna in a beam overlap region, wherein the third target antenna is at least one of the first antenna, the second antenna, and the beam overlap region is the overlapping portion of the beam coverage area of ​​the main communication device and the beam coverage area of ​​the second target device; and maintaining the connection between the main communication antenna and the main communication device and communicating with the second target device via the third target antenna if the signal strength of the non-terrestrial network signal transmitted by the second target device received by the third target antenna is greater than a second threshold.

[0118] For details regarding beam overlap regions, please refer to [link / reference]. Figure 1 The relevant descriptions in the illustrated embodiments will not be repeated here.

[0119] For this implementation method, you can continue to refer to... Figure 12aAt the first moment, the third antenna can simultaneously detect network signals transmitted by two non-terrestrial network devices; at the second moment, the third antenna and the first antenna can simultaneously detect network signals transmitted by two non-terrestrial network devices; at the third moment, the first antenna, the second antenna, and the third antenna can simultaneously detect network signals transmitted by two non-terrestrial network devices. Furthermore, in the beam overlap region, while the third target antenna can simultaneously detect network signals transmitted by two non-terrestrial network devices, there is always a main communication antenna communicating with the main communication device. This main communication antenna is one of the three antennas, and this main communication device is the second target device among the two non-terrestrial network devices. Therefore, if the signal strength of the non-terrestrial network signal transmitted by the second target device received by the third target antenna is greater than a second threshold, the connection between the main communication antenna and the main communication device is maintained, and communication with the second target device is continued through the third target antenna. In other words, when the arrival of the next non-terrestrial network device is detected, the current non-terrestrial network device communication is maintained without interruption, and communication with the next non-terrestrial network device continues using the third target antenna. This can solve the problem of network dropouts when switching between non-terrestrial network devices, and can also improve the problems of shorter call time windows and slow detection of the next non-terrestrial network device caused by the antenna not being able to be aligned with the non-terrestrial network device in time.

[0120] In one embodiment, the first threshold and the second threshold may be equal or unequal.

[0121] In one embodiment, after maintaining the connection between the main communication antenna and the main communication device and communicating with the second target device through the third target antenna, the method further includes: acquiring a first signal strength and a second signal strength, wherein the first signal strength is the signal strength of a non-terrestrial network signal transmitted by the second target device detected by the third target antenna, and the second signal strength is the signal strength of a non-terrestrial network signal transmitted by the main communication device detected by the main communication antenna; and disconnecting the connection between the main communication antenna and the main communication device if at least one of the first signal strengths is greater than the second signal strength.

[0122] In one embodiment, communicating with the second target device via the third target antenna may include: acquiring the signal strength of a non-terrestrial network signal transmitted by the second target device detected by the third target antenna; determining a fourth target antenna as the antenna corresponding to the largest signal strength among the various signal strengths; and communicating with the second target device via the fourth target antenna. In other words, the antenna with the largest detected signal strength is always selected to communicate with the corresponding non-terrestrial network device to ensure optimal communication quality and efficiency.

[0123] In one embodiment, communicating with the second target device via the third target antenna may include: acquiring the signal strength of a non-terrestrial network signal transmitted by the second target device detected by the third target antenna; determining a fifth target antenna as the antenna whose detected signal strength is greater than a third threshold; and communicating with the second target device via the fifth target antenna. In other words, the third threshold is set to ensure communication quality. Therefore, if the signal strength detected by any of the third target antennas is greater than the third threshold, it indicates that the antenna can provide reliable communication service. This allows one or more antennas to communicate with the second target device simultaneously, enabling the terminal device to maximize communication efficiency based on real-time signal strength changes.
