[0027] Figure 1 The present invention is a schematic flow chart illustrating a method for sending configuration information according to an embodiment of the present disclosure. The configuration information sending method illustrated in this embodiment can be applied to a base station that can communicate with a terminal in a non-terrestrial network, such as via a satellite in the air. Satellite communication methods include, but are not limited to, transparent transmission and non-transparent transmission (which may be referred to as on-board regeneration).
[0028] In one embodiment, the terminal includes but is not limited to communication devices such as mobile phones, tablet computers, wearable devices, sensors, and Internet of Things devices. The base station includes but is not limited to base stations in communication systems such as 4G base stations, 5G base stations, and 6G base stations.
[0029] like Figure 1 As shown, the configuration information sending method may include the following steps:
[0030] In step S101, configuration information is sent to a terminal, wherein the configuration information is used to indicate the configuration of multiple beams when a satellite communicates with the terminal through multiple beams.
[0031] In one embodiment, the base station can determine the configuration of multiple beams when the satellite communicates with the terminal through multiple beams, and then generate configuration information based on the determined configuration and send it to the terminal, so that the terminal can smoothly receive the signals sent by the satellite through multiple beams according to the configuration in the configuration information, thereby ensuring good communication between the terminal and the satellite.
[0032] In one embodiment, the configuration includes at least one of the following: identification information of each of the beams; frequency domain resource information of each of the beams; service time information of each of the beams; polarization information of each of the beams; main service beams and auxiliary service beams among the multiple beams; and timing deviation information between different beams among the multiple beams.
[0033] In one embodiment, all or part of the configurations may be determined autonomously by the satellite, or by the base station, or by negotiation between the satellite and the base station, or by agreement.
[0034] In one embodiment, when a terminal communicates with a satellite, it may receive multiple satellite beams. However, the satellite does not necessarily communicate with the terminal simultaneously through all of these beams, but only through the beam corresponding to the identification information. Therefore, when the terminal receives multiple beams, it can determine the identification of each beam, for example, based on the beam's reference signal, and then determine the target identification associated with the beam information. By informing the terminal of the identification information of each beam, the terminal can receive only the signal transmitted by the beam corresponding to the identification information when receiving a satellite beam, thus avoiding the terminal receiving signals from beams not used for communication with the terminal, which would waste resources.
[0035] In one embodiment, the frequency domain resource information includes at least one of the following: an operating frequency and an operating bandwidth. Based on the frequency information, the terminal can determine the operating frequency and operating bandwidth of the beam emitted by the satellite, and then receive the signal in the beam within the determined operating frequency and operating bandwidth.
[0036] In one embodiment, the service time information includes at least one of the following: service start time, service end time, and service duration.
[0037] For example, the service time information includes the service start time and the service end time, indicating that the beam can provide services from the service start time to the service end time. Based on this, the terminal can receive the beam between the service start time and the service end time to ensure successful reception of the beam.
[0038] For example, the service time information includes the service start time and the service duration, which means that the beam can provide service from the service start time, and the duration of the service is the service duration. Based on this, the terminal can receive the beam from the service start time within the service duration to ensure successful reception of the beam.
[0039] The service time information may include actual time information or logical time information, such as a system frame number, a time slot number, a time domain symbol number, etc.
[0040] In one embodiment, the terminal can determine the coverage range of the satellite signal (which can be understood as the angle range) based on the main service beam, and then can receive the auxiliary service beam within this coverage range. The auxiliary service beam can carry data that needs to be interacted.
[0041] In one embodiment, the terminal can determine the polarization mode required for receiving the corresponding beam based on the polarization information, and then use the polarization mode corresponding to the beam to receive the signal of the beam. The polarization mode includes at least one of the following: linear polarization, circular polarization, left-hand polarization, and right-hand polarization.
[0042] For example, if the polarization mode of beam 1 is determined to be left-hand polarization and the polarization mode of beam 2 is right-hand polarization based on the polarization information, the terminal can receive the downlink signal sent by the satellite through beam 1 using left-hand polarization and the downlink signal sent by the satellite through beam 2 using right-hand polarization, thereby ensuring that the terminal can successfully receive the signal sent by the satellite through each beam.
[0043] In one embodiment, different beams emitted by a satellite generally have different directions, so the distances from different beams to the terminal are also different. The information simultaneously sent by the satellite through different beams will arrive at the terminal at different times, which may make it difficult for the terminal to accurately calculate the transmission delay of the signal received on different beams.
[0044] Based on the timing deviation information between different beams sent to the terminal, the terminal determines the delay difference of the satellite transmitting signals through different beams. In this case, the terminal can first determine a reference beam (for example, indicated by the base station or pre-agreed), and the timing deviation information can be the timing deviation relative to the reference beam. The delay of the satellite transmitting signals through the reference beam can be determined for the terminal (for example, indicated by the base station or calculated autonomously by the terminal in some way).
[0045] For example, using beam1 and beam2 as the reference beam, the timing offset information includes the timing offset between beam1 and beam2. For example, a timing offset of t21 represents the duration between the time the terminal receives the signal via beam2 and the time it receives the signal via beam1. This can be a positive number (indicating that beam2's signal is received later) or a negative number (indicating that beam2's signal is received earlier). The terminal can determine that the delay of the satellite transmitting the signal via beam1 is T0. Based on the timing offset, the terminal can determine that the delay of the satellite transmitting the signal via beam2 is T0 + t21.
[0046] Similarly, if the satellite also communicates with the terminal through beam3, the timing deviation information also includes the timing deviation between beam1 and beam3. For example, if the timing deviation is t31, then the delay of the satellite transmitting the signal through beam2 can be determined based on the timing deviation as T0 + t31. Similarly, the delay of the satellite transmitting the signal through each beam can be determined.
[0047] After determining the transmission delay, the terminal can perform time-domain compensation for different beams based on the transmission delay. For example, the terminal can determine the timing advance (TA) based on the transmission delay, and then compensate the terminal's signal transmission to the satellite on the corresponding beam based on the TA. For example, the TA2 determined based on T0 + t21 can be used to compensate for the terminal's transmission to the satellite on beam2 (and the satellite's reception on beam2). This ensures good communication between the terminal and the satellite.
[0048] In one embodiment, the timing offset information is determined based on at least a signal propagation distance when the satellite communicates with the terminal through each of the beams.
[0049] The base station can determine the position of the terminal, and determine the position of the satellite when communicating with the terminal based on the satellite's motion trajectory, and then determine the signal propagation distance when the satellite communicates with the terminal through each beam based on the satellite's position and the angle of the beam emitted by the satellite. Then, based on the signal propagation distance, it can determine the duration of the signal transmission when the satellite communicates with the terminal through each beam, and then determine the timing deviation information between different beams based on the difference between the transmission durations corresponding to the beams.
[0050] It should be noted that the timing deviation information can be changed. Since it is generally difficult for the terminal to accurately determine the signal propagation distance when the satellite communicates through different beams, but the base station can, the following mainly describes how the base station updates the timing deviation information through two embodiments.
[0051] Figure 2 FIG. 1 is a schematic flow chart of another method for sending configuration information according to an embodiment of the present disclosure. Figure 2 As shown, the configuration includes timing offset information between different beams in the multiple beams, and the method further includes:
[0052] In step S201, a request message sent by the terminal is received, wherein the terminal sends the request message to the base station when a relationship between transmission times corresponding to each beam in a process of signal transmission from the satellite to the terminal satisfies a preset relationship;
[0053] In step S202, update information for updating the timing offset information is sent to the terminal.
[0054] In one embodiment, after obtaining the timing offset information from the configuration information, the terminal may detect the timing offset information, for example, periodically. The terminal may determine the time when the satellite transmits the signal on the beam and the time when the terminal receives the signal, and may further calculate the transmission time based on the transmission time and the reception time.
[0055] If the satellite's position and attitude relative to the terminal in space change little, the transmission time and timing offset information remain essentially unchanged. However, if the satellite's position or attitude relative to the terminal changes significantly, such as if the satellite experiences significant displacement, the transmission time will change, resulting in a significant change in the timing offset. In this case, the previously received timing offset information is no longer applicable, and a request message is sent to the base station.
[0056] For example, the terminal can determine whether the relationship between the transmission times satisfies a preset relationship, where satisfying the preset relationship may mean that the difference between the transmission times is greater than the preset difference, or at least one transmission time is greater than a preset duration. In this case, it can be determined that the timing deviation information needs to be updated, thereby sending a request information to the base station.
[0057] After receiving the request information from the terminal, the base station can re-determine the timing offset information, generate update information based on the information, and send the update information to the terminal so that the terminal can determine the updated timing offset information and ensure that the terminal can perform operations based on accurate timing offset information.
[0058] Figure 3 FIG. 1 is a schematic flow chart of another method for sending configuration information according to an embodiment of the present disclosure. Figure 3 As shown, the configuration includes timing offset information between different beams in the multiple beams, and the method further includes:
[0059] In step S301, update information for updating the timing offset information is periodically sent to the terminal.
[0060] In one embodiment, the terminal does not need to send request information to the base station. Instead, the base station periodically sends update information to the terminal, thereby helping to reduce the load on the terminal side.
[0061] Figure 4 The present invention is a schematic flow chart illustrating a method for receiving configuration information according to an embodiment of the present disclosure. The configuration information receiving method illustrated in this embodiment can be applied to a terminal that can communicate with a base station in a non-terrestrial network, such as via a satellite in the air. Satellite communication methods include, but are not limited to, transparent transmission and non-transparent transmission (which may be referred to as on-board regeneration).
[0062] In one embodiment, the terminal includes but is not limited to communication devices such as mobile phones, tablet computers, wearable devices, sensors, and Internet of Things devices. The base station includes but is not limited to base stations in communication systems such as 4G base stations, 5G base stations, and 6G base stations.
[0063] like Figure 4As shown, the configuration information sending method may include the following steps:
[0064] In step S401, configuration information sent by a base station is received;
[0065] In step S402, the configuration of the multiple beams when the satellite communicates with the terminal through the multiple beams is determined according to the configuration information.
[0066] In one embodiment, the base station can determine the configuration of multiple beams when the satellite communicates with the terminal through multiple beams, and then generate configuration information based on the determined configuration and send it to the terminal, so that the terminal can smoothly receive the signals sent by the satellite through multiple beams according to the configuration in the configuration information, thereby ensuring good communication between the terminal and the satellite.
[0067] In one embodiment, the configuration includes at least one of the following: identification information of each of the beams; frequency domain resource information of each of the beams; service time information of each of the beams; polarization information of each of the beams; main service beams and auxiliary service beams among the multiple beams; and timing deviation information between different beams among the multiple beams.
[0068] In one embodiment, all or part of the configurations may be determined autonomously by the satellite, or by the base station, or by negotiation between the satellite and the base station, or by agreement.
[0069] In one embodiment, when a terminal communicates with a satellite, it may receive multiple beams from the satellite. However, the satellite does not necessarily communicate with the terminal through all of the beams simultaneously, but only through the beam corresponding to the identification information. Therefore, when the terminal receives multiple beams, it may determine the identification of each beam, for example, by determining the identification of the beam based on the reference signal of the beam, and then determine the target identification belonging to the beam information.
[0070] By informing the terminal of the identification information of each beam, when the terminal receives the satellite beam, it can only receive the signal sent by the beam corresponding to the identification information, avoiding the terminal receiving the signal in the beam that is not used for communication with the terminal and causing waste of resources.
[0071] In one embodiment, the frequency domain resource information includes at least one of the following: an operating frequency and an operating bandwidth. Based on the frequency information, the terminal can determine the operating frequency and operating bandwidth of the beam emitted by the satellite, and then receive the signal in the beam within the determined operating frequency and operating bandwidth.
[0072] In one embodiment, the service time information includes at least one of the following: service start time, service end time, and service duration.
[0073] For example, the service time information includes the service start time and the service end time, indicating that the beam can provide services from the service start time to the service end time. Based on this, the terminal can receive the beam between the service start time and the service end time to ensure successful reception of the beam.
[0074] For example, the service time information includes the service start time and the service duration, which means that the beam can provide service from the service start time, and the duration of the service is the service duration. Based on this, the terminal can receive the beam from the service start time within the service duration to ensure successful reception of the beam.
[0075] The service time information may include actual time information or logical time information, such as a system frame number, a time slot number, a time domain symbol number, etc.
[0076] In one embodiment, the terminal can determine the coverage range of the satellite signal (which can be understood as the angle range) based on the main service beam, and then can receive the auxiliary service beam within this coverage range. The auxiliary service beam can carry data that needs to be interacted.
[0077] In one embodiment, the terminal can determine the polarization mode required for receiving the corresponding beam based on the polarization information, and then use the polarization mode corresponding to the beam to receive the signal of the beam. The polarization mode includes at least one of the following: linear polarization, circular polarization, left-hand polarization, and right-hand polarization.
[0078] For example, if the polarization mode of beam 1 is determined to be left-hand polarization and the polarization mode of beam 2 is right-hand polarization based on the polarization information, the terminal can receive the downlink signal sent by the satellite through beam 1 using left-hand polarization and the downlink signal sent by the satellite through beam 2 using right-hand polarization, thereby ensuring that the terminal can successfully receive the signal sent by the satellite through each beam.
[0079] In one embodiment, different beams emitted by a satellite generally have different directions, so the distances from different beams to the terminal are also different. The information simultaneously sent by the satellite through different beams will arrive at the terminal at different times, which may make it difficult for the terminal to accurately calculate the transmission delay of the signal received on different beams.
[0080] Based on the timing deviation information between different beams sent to the terminal, the terminal determines the delay difference of the satellite transmitting signals through different beams. In this case, the terminal can first determine a reference beam (for example, indicated by the base station or pre-agreed), and the timing deviation information can be the timing deviation relative to the reference beam. The delay of the satellite transmitting signals through the reference beam can be determined for the terminal (for example, indicated by the base station or calculated autonomously by the terminal in some way).
[0081] For example, using beam1 and beam2 as the reference beam, the timing offset information includes the timing offset between beam1 and beam2. For example, a timing offset of t21 represents the duration between the time the terminal receives the signal via beam2 and the time it receives the signal via beam1. This can be a positive number (indicating that beam2's signal is received later) or a negative number (indicating that beam2's signal is received earlier). The terminal can determine that the delay of the satellite transmitting the signal via beam1 is T0. Based on the timing offset, the terminal can determine that the delay of the satellite transmitting the signal via beam2 is T0 + t21.
[0082] Similarly, if the satellite also communicates with the terminal through beam3, the timing deviation information also includes the timing deviation between beam1 and beam3. For example, if the timing deviation is t31, then the delay of the satellite transmitting the signal through beam2 can be determined based on the timing deviation as T0 + t31. Similarly, the delay of the satellite transmitting the signal through each beam can be determined.
[0083] After determining the transmission delay, the terminal can perform time-domain compensation for different beams based on the transmission delay. For example, the terminal can determine the timing advance (TA) based on the transmission delay, and then compensate the terminal's signal transmission to the satellite on the corresponding beam based on the TA. For example, the TA2 determined based on T0 + t21 can be used to compensate for the terminal's transmission to the satellite on beam2 (and the satellite's reception on beam2). This ensures good communication between the terminal and the satellite.
[0084] In one embodiment, the timing offset information is determined based on at least a signal propagation distance when the satellite communicates with the terminal through each of the beams.
[0085] The base station can determine the position of the terminal, and determine the position of the satellite when communicating with the terminal based on the satellite's motion trajectory, and then determine the signal propagation distance when the satellite communicates with the terminal through each beam based on the satellite's position and the angle of the beam emitted by the satellite. Then, based on the signal propagation distance, it can determine the duration of the signal transmission when the satellite communicates with the terminal through each beam, and then determine the timing deviation information between different beams based on the difference between the transmission durations corresponding to the beams.
[0086] It should be noted that the timing deviation information can be changed. Since it is generally difficult for the terminal to accurately determine the signal propagation distance when the satellite communicates through different beams, but the base station can, the following mainly describes how the base station updates the timing deviation information through two embodiments.
[0087] Figure 5 FIG. 1 is a schematic flow chart of another configuration information receiving method according to an embodiment of the present disclosure. Figure 5 The configuration includes timing deviation information between different beams in the multiple beams, and the method further includes:
[0088] In step S501, when the satellite communicates with the terminal through each beam, a transmission time corresponding to each beam in a process in which a signal is transmitted from the satellite to the terminal is measured;
[0089] In step S502, when the relationship between the transmission times corresponding to each beam does not satisfy a preset relationship, sending request information to the base station;
[0090] In step S503, update information for updating the timing offset information sent by the base station according to the request information is received.
[0091] In one embodiment, after obtaining the timing offset information from the configuration information, the terminal may detect the timing offset information, for example, periodically. The terminal may determine the time when the satellite transmits the signal on the beam and the time when the terminal receives the signal, and may further calculate the transmission time based on the transmission time and the reception time.
[0092] If the satellite's position and attitude relative to the terminal in space change little, the transmission time and timing offset information remain essentially unchanged. However, if the satellite's position or attitude relative to the terminal changes significantly, such as if the satellite experiences significant displacement, the transmission time will change, resulting in a significant change in the timing offset. In this case, the previously received timing offset information is no longer applicable, and a request message is sent to the base station.
[0093] For example, the terminal can determine whether the relationship between the transmission times satisfies a preset relationship, where satisfying the preset relationship may mean that the difference between the transmission times is greater than the preset difference, or at least one transmission time is greater than a preset duration. In this case, it can be determined that the timing deviation information needs to be updated, thereby sending a request information to the base station.
[0094] After receiving the request information from the terminal, the base station can re-determine the timing offset information, generate update information based on the information, and send the update information to the terminal so that the terminal can determine the updated timing offset information and ensure that the terminal can perform operations based on accurate timing offset information.

Figure 6The configuration includes timing deviation information between different beams in the multiple beams, and the method further includes:
[0096] In step S601, update information for updating the timing offset information sent by the base station is periodically received.
[0097] In one embodiment, the terminal does not need to send request information to the base station. Instead, the base station periodically sends update information to the terminal, thereby helping to reduce the load on the terminal side.
