[0040] The following will be combined with the drawings in the present disclosure to clearly and completely describe the technical solutions in the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0041] It should be noted that, in the present disclosure, words such as "exemplary" or "for example" are used to indicate examples, illustrations or descriptions. Any embodiment or design described as "exemplary" or "for example" in the present disclosure should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.

[0042] In the following, the terms "first" and "second" are used for descriptive purposes only and are not to be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features.

[0043] In the description of the present disclosure, unless otherwise specified, " / " means "or", for example, A / B can mean A or B. "And / or" in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships, for example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. In addition, "at least one" means one or more, and "a plurality" means two or more.

[0044] First type of communication: The user communicates with the first type of equipment / entity through connection. For example, the first type of communication is TN, where the user communicates directly with the base station through connection.

[0045] Second type of communication: The user communicates with the second type of equipment / entity. For example, the second type of communication is NTN, where the user communicates with a satellite connection.

[0046] Hereinafter, TN / NTN will be used as an example of the first / second type of communication to explain the method for the first / second type of communication to share spectrum. The first / second type of communication may also include communication types other than TN / NTN.

[0047] 1. NTN

[0048] NTN can also be called a satellite network, which mainly refers to a communication network based on non-ground infrastructure. In NTN, satellites, unmanned aerial vehicles (UAVs), and high altitude platforms (HAPs) can be regarded as base stations, or as relays between ground base stations / gateways and terminals. Terminals can connect to satellites to achieve communication through satellites. In areas that cannot be directly covered by ground base stations, terminals can connect to satellites for communication, thereby achieving full coverage of the connection.

[0049] Figure 1 A schematic diagram of the structure of an NTN is shown. Exemplarily, the satellite 101 can be regarded as a base station, thereby communicating with the terminal 102 on the ground, and the link between the satellite 101 and the terminal 102 is a service link. In addition, the satellite 101 is communicated with the access network device 103, and the link between the satellite 101 and the access network device 103 is a feeder link. The satellite 101 is public for all terminals in the same cell. Among them, the access network device 103 includes a base station and a gateway.

[0050] 2. TN

[0051] TN mainly refers to communication networks based on ground infrastructure. They provide communication services through ground base stations, antennas, and wireless / wired transmission equipment. For example, the third generation mobile communication technology (4th generation mobile communication technology, 3G) universal mobile telecommunications system (UMTS) and the fourth generation mobile communication technology (4G) long term evolution (LTE) are both TN networks. It should be understood that the fifth generation mobile communication technology (5G) new radio (NR) can support both TN and NTN. Future mobile communication technologies, including the sixth generation mobile communication technology (5G), are expected to continue to support TN and NTN.

[0052] 3. Spectrum Resources

[0053] In wireless communication, spectrum resources are very important transmission resources and are the key to the smooth operation of wireless communication systems. For example, NTN (also known as satellite network) and TN are allocated dedicated spectrum resources. However, spectrum resources are limited. With the rapid development of wireless communication technology, available spectrum resources are becoming increasingly scarce. Therefore, how to improve the utilization rate of spectrum resources is a technical problem that needs to be solved urgently.

[0054] In order to solve the above technical problems, the embodiments of the present disclosure provide a signal transmission method, which can transmit the signal of the first type of communication and the signal of the second type of communication on the target frequency domain resources. In this way, the signals of the first type of communication and the second type of communication are transmitted on the same frequency domain resources, and there is no need to configure dedicated frequency domain resources for the first type of communication and the second type of communication respectively, thereby saving frequency domain resources and improving the utilization rate of frequency domain resources.

[0055] The signal transmission method provided by the embodiments of the present disclosure can be applied to Figure 2 In the communication system, Figure 2 As shown, the communication system includes: a first node 201 and a second node 202.

[0056] The first node 201 and the second node 202 are in communication connection. The first node 201 may be a base station, a satellite, a terminal, etc. The second node 202 may be a satellite, a base station, a terminal, a tag, etc. For example, when the first node 201 is a terminal, the second node 202 may be a base station (or a ground communication base station) or a satellite. When the first node 202 is a base station or a satellite, the second node 202 may be a terminal. It should be understood that the satellite in the NTN may also be understood as an NTN base station.

[0057] In the embodiment of the present disclosure, the first node 201 can transmit the signal of the terrestrial communication network and the signal of the non-terrestrial communication network on the target frequency domain resources. Accordingly, when the second node 201 is a satellite, the second node 201 can receive the signal of the non-terrestrial communication network sent by the first node 201 on the target frequency domain resources. Alternatively, when the second node 201 is a base station, the second node 201 can receive the signal of the terrestrial communication network sent by the first node 201 on the target frequency domain resources.

[0058] It should be noted that Figure 2 This is just an exemplary framework diagram. Figure 2 The number of devices included in the Figure 2 In addition to the devices shown, the communication system may also include other devices, such as relay nodes.

[0059] The application scenarios of the embodiments of the present disclosure are not limited. The system architecture and business scenarios described in the embodiments of the present disclosure are intended to more clearly illustrate the technical solutions of the embodiments of the present disclosure, and do not constitute a limitation on the technical solutions provided by the embodiments of the present disclosure. It is known to those skilled in the art that with the evolution of network architecture and the emergence of new business scenarios, the technical solutions provided by the embodiments of the present disclosure are also applicable to similar technical problems.

[0060] The signal transmission method provided by the embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings.

[0061] The signal transmission method provided by the embodiment of the present disclosure can be applied to Figure 2 A first node 201 in a communication system is shown. Figure 3 A schematic diagram showing a process of a signal transmission method Figure 1 ,like Figure 3 As shown, the signal transmission method includes the following S301.

[0062] S301. A first node sends a first type of communication signal and a second type of communication signal on a target frequency domain resource.

[0063] In the embodiments of the present disclosure, the following description will be made by taking the first type of communication as a terrestrial communication network and the second type of communication as a non-terrestrial communication network as an example.

[0064] Among them, the shared frequency domain resources shared by the terrestrial communication network (hereinafter referred to as TN) and the non-terrestrial communication network (hereinafter referred to as NTN) may include at least one of the following: bandwidth part (BWP), resource block (RB), resource block group (or set) RB group / set, subband, band, carrier, channel. In addition, TN and NTN can also share time domain resources, and the time domain resources may include at least one of the following: code element, symbol, time slot, subframe, frame. Optionally, the target frequency domain resource can be a shared frequency domain resource of the first type of communication and the second type of communication, and can be any frequency domain resource. The following description is made in a manner that the target frequency domain resource is the shared frequency domain resource.

[0065] On the shared frequency domain resources, the first node can send TN signals or NTN signals, that is, the shared frequency domain resources are transmission resources shared by TN and NTN. In this way, there is no need to configure transmission resources for TN and NTN separately, thereby improving the utilization of spectrum resources. In addition, the terminal can connect to TN or NTN through the terminal. For example, when the TN transmission quality decreases, the NTN signal is transmitted through the shared frequency domain resources, thereby improving the user's full connection experience.

[0066] In a possible implementation, since NTN and TN are respectively allocated dedicated transmission resources (or frequency domain resources, spectrum resources, etc.) in an exclusive manner, that is, the transmission resources of NTN can only transmit NTN signals, but not TN signals, and correspondingly, the transmission resources of TN can only transmit TN signals, but not NTN signals. Therefore, when transmitting TN signals and NTN signals through shared frequency domain resources, scenarios 1 to 3 may be included:

[0067] Scenario 1: Target frequency domain resources include frequency domain resources configured for TN

[0068] The resources configured for the TN include transmission resources configured for the TN, i.e., transmission resources used to transmit TN signals. The shared frequency domain resources may include frequency domain resources configured for the TN, and the NTN shares the transmission resources of the TN in a supplementary manner. In this way, when the first node is connected to the NTN, it can also send signals on the resources configured for the TN, so there is no need to configure special frequency domain resources for the NTN, which can save frequency domain resources and improve resource utilization.

[0069] In some embodiments, the frequency domain resources configured for TN include a first frequency domain resource, and / or a second frequency domain resource. The first frequency domain resource is used to transmit the uplink (UL) signal of TN, that is, the first frequency domain resource is an uplink transmission resource (e.g., frequency band F1) for transmitting the uplink TN signal; the second frequency domain resource is used to transmit the downlink signal of TN, that is, the second frequency domain resource is a downlink transmission resource (e.g., frequency band F2) for transmitting the downlink (DL) TN signal. For example, TN transmits uplink TN signals on frequency band F1 and transmits downlink TN signals on frequency band F2. It should be understood that at this time, the TN signal is transmitted in a frequency division multiplexing or frequency division duplex (FDD) manner, and the shared frequency domain resources are FDD resources or FDD spectrum.

[0070] It should be noted that in different sharing modes, the shared frequency domain resources include different resources, or the shared frequency domain resources are used to transmit different signal types. The shared frequency domain resources can meet any one of Modes 1-1 to 1-9. The following will describe nine modes of NTN sharing resources configured for TN:

[0071] Mode 1-1: Transmitting the uplink signal of NTN on the first frequency domain resource, and transmitting the downlink signal of NTN on the second frequency domain resource. In this case, the shared frequency domain resource includes the first frequency domain resource and the second frequency domain resource.

[0072] NTN uplink transmission occupies the uplink transmission resources configured for TN, that is, the first frequency domain resources; NTN downlink transmission occupies the downlink transmission resources configured for TN, that is, the second frequency domain resources. In this way, NTN signal transmission can occupy the transmission resources configured for TN, and the shared frequency domain resources are used for the same direction of the transmitted signals (that is, NTN uplink and TN uplink are transmitted on the first frequency domain resources, or NTN downlink and TN downlink are transmitted on the second frequency domain resources), which can reduce cross-link interference. In addition, the uplink and downlink resources configured for TN can be shared with NTN, thereby further improving spectrum utilization.

[0073] Figure 4 A schematic diagram of a mode 1-1 is shown. Exemplarily, taking the first frequency domain resource as frequency band F1 and the second frequency domain resource as frequency band F2 as an example, the shared frequency domain resources include F1 and F2, F1 is used to transmit TN uplink signals and NTN uplink signals, and F2 is used to transmit NTN downlink signals and TN downlink signals.

[0074] Mode 1-2: Transmitting the downlink signal of NTN on the first frequency domain resource, and transmitting the uplink signal of NTN on the second frequency domain resource. In this case, the shared frequency domain resource includes the first frequency domain resource and the second frequency domain resource.

[0075] NTN downlink transmission occupies the uplink transmission resources configured for TN, that is, the first frequency domain resources; NTN uplink transmission occupies the downlink transmission resources of TN, that is, the second frequency domain resources. In this way, NTN transmission occupies the transmission resources of TN, and the shared frequency domain resources are used to transmit signals in opposite directions (that is, NTN downlink and TN uplink are transmitted on the first frequency domain resources, or NTN uplink and TN downlink are transmitted on the second frequency domain resources), which can reduce interference from co-directional signals. In addition, both the uplink and downlink resources of TN can be shared with NTN, thereby further improving spectrum utilization.

[0076] Figure 5 A schematic diagram of a method 1-2 is shown. Exemplarily, taking the first frequency domain resource as frequency band F1 and the second frequency domain resource as frequency band F2 as an example, the shared frequency domain resources include F1 and F2, F1 is used to transmit TN uplink signals and NTN downlink signals, and F2 is used to transmit NTN uplink signals and TN downlink signals.

[0077] Mode 1-3: Transmitting the uplink signal and the downlink signal of the NTN on the first frequency domain resource. The uplink signal and the downlink signal of the NTN are transmitted in a time division multiplexing or time division duplex (TDD) manner.

[0078] In this case, NTN downlink transmission and NTN uplink transmission occupy the first frequency domain resources configured for TN, and the second frequency domain resources configured for TN are not shared with NTN. Therefore, the shared frequency domain resources include the first frequency domain resources.

[0079] The uplink and downlink transmission of NTN both use the first frequency domain resources configured for TN, while the second frequency domain resources configured for TN are only used for downlink transmission of TN. In this way, since the second frequency domain resources of TN are only used to transmit the downlink signal of TN without interference from the signal of NTN, this method can not only improve resource utilization, but also give priority to guaranteeing the quality of downlink transmission of TN, and is suitable for the scenario where it is necessary to give priority to guaranteeing the downlink transmission of TN.

[0080] Figure 6 A schematic diagram of a method 1-3 is shown. For example, taking the first frequency domain resource as frequency band F1 and the second frequency domain resource as frequency band F2 as an example, the spectrum resources configured for TN include F1 and F2, F1 is used to transmit NTN uplink signals and NTN downlink signals, as well as TN uplink signals, and F2 is used to transmit TN downlink signals. NTN uplink signals and downlink signals are transmitted in a TDD manner, and the frequency domain resources for transmitting the uplink signals and the downlink signals can overlap.

[0081] Mode 1-4: Transmitting the uplink signal and downlink signal of NTN on the second frequency domain resource. The uplink signal and downlink signal of NTN are transmitted in TDD mode.

[0082] In this case, NTN downlink transmission and NTN uplink transmission occupy the second frequency domain resources configured for TN, and the first frequency domain resources configured for TN are not shared with NTN. Therefore, the shared frequency domain resources include the second frequency domain resources.

[0083] Both the uplink and downlink transmissions of NTN use the second frequency domain resources configured for TN, while the first frequency domain resources configured for TN are only used to transmit the uplink transmission of TN. In this way, since the first frequency domain resources of TN are only used to transmit the uplink signal of TN without interference from the signal of NTN, this method can not only improve resource utilization, but also give priority to guaranteeing the quality of uplink transmission of TN, and can be adapted to the scenario where it is necessary to give priority to guaranteeing the uplink transmission of TN. For example, in some simulation or test scenarios, when TN and NTN share the spectrum, this method can be used when the interference received by the uplink transmission of TN is more serious.

[0084] Figure 7A schematic diagram of a method 1-4 is shown. Exemplarily, taking the first frequency domain resource as frequency band F1 and the second frequency domain resource as frequency band F2 as an example, the spectrum resources of TN include F1 and F2, F1 is used to transmit TN uplink signals, and F2 is used to transmit NTN uplink signals and NTN downlink signals, as well as TN downlink signals. The uplink signal and downlink signal of NTN are transmitted in a TDD manner, and the frequency domain resources for transmitting the uplink signal and the downlink signal can overlap.

[0085] Mode 1-5: Transmitting the uplink signal and the downlink signal of NTN on the first frequency domain resource. The uplink signal and the downlink signal of NTN are transmitted in FDD mode.

[0086] In this case, NTN downlink transmission and NTN uplink transmission occupy the first frequency domain resources configured for TN, and the second frequency domain resources configured for TN are not shared with NTN. Therefore, the shared frequency domain resources include the first frequency domain resources.

[0087] The uplink and downlink transmission of NTN both use the first frequency domain resources configured for TN, while the second frequency domain resources configured for TN are only used for downlink transmission of TN. In this way, since the second frequency domain resources of TN are only used to transmit the downlink signal of TN without interference from the signal of NTN, this method can not only improve resource utilization, but also give priority to guaranteeing the quality of downlink transmission of TN, and is suitable for the scenario where it is necessary to give priority to guaranteeing the downlink transmission of TN.

[0088] Figure 8 A schematic diagram of a method 1-5 is shown. Exemplarily, taking the first frequency domain resource as frequency band F1 and the second frequency domain resource as frequency band F2 as an example, the spectrum resources configured for TN include F1 and F2, F1 is used to transmit NTN uplink signals and NTN downlink signals, as well as TN uplink signals, and F2 is used to transmit TN downlink signals. NTN uplink signals and downlink signals are transmitted in an FDD manner, and the time domain resources for transmitting the uplink signals and the downlink signals may overlap. For example, frequency band F1 includes frequency band F1-1 and frequency band F1-2, frequency band F1-1 is used to transmit NTN uplink signals, and frequency band F1-2 is used to transmit NTN downlink signals.

[0089] Mode 1-6: Transmitting the uplink signal and downlink signal of NTN on the second frequency domain resource. The uplink signal and downlink signal of NTN are transmitted in FDD mode.

[0090] In this case, NTN downlink transmission and NTN uplink transmission occupy the second frequency domain resources configured for TN, and the first frequency domain resources configured for TN are not shared with NTN. Therefore, the shared frequency domain resources include the second frequency domain resources.

[0091] Both the uplink and downlink transmissions of NTN use the second frequency domain resources configured for TN, while the first frequency domain resources configured for TN are only used to transmit the uplink transmission of TN. In this way, since the first frequency domain resources of TN are only used to transmit the uplink signal of TN without interference from the signal of NTN, this method can not only improve resource utilization, but also give priority to guaranteeing the quality of uplink transmission of TN, and can be adapted to the scenario where it is necessary to give priority to guaranteeing the uplink transmission of TN. For example, in some simulation or test scenarios, when TN and NTN share the spectrum, this method can be used when the interference received by the uplink transmission of TN is more serious.

[0092] Fig. 9 A schematic diagram of a method 1-6 is shown. Exemplarily, taking the first frequency domain resource as frequency band F1 and the second frequency domain resource as frequency band F2 as an example, the spectrum resources configured for TN include F1 and F2, F1 is used to transmit TN uplink signals, and F2 is used to transmit NTN uplink signals and NTN downlink signals, as well as TN downlink signals. The uplink signal and downlink signal of NTN are transmitted in an FDD manner, and the time domain resources for transmitting the uplink signal and the downlink signal can overlap. For example, frequency band F2 includes frequency band F2-1 and frequency band F2-2, frequency band F2-1 is used to transmit the uplink signal of NTN, and frequency band F2-2 is used to transmit the downlink signal of NTN.

[0093] Mode 1-7: Transmitting an uplink signal or a downlink signal of the NTN on the first frequency domain resource.

[0094] In this case, NTN downlink transmission or NTN uplink transmission occupies the first frequency domain resources configured for TN, and the second frequency domain resources configured for TN are not shared with NTN. Therefore, the shared frequency domain resources include the first frequency domain resources.

[0095] The uplink transmission or downlink transmission of NTN shares the first frequency domain resources of TN, while the second frequency domain resources of TN are only used to transmit the downlink transmission of TN. In this way, since the second frequency domain resources of TN are only used to transmit the downlink signal of TN without interference from the signal of NTN, this method can not only improve resource utilization, but also give priority to guaranteeing the quality of downlink transmission of TN, and can be adapted to the scenario where it is necessary to give priority to guaranteeing the downlink transmission of TN.

[0096] In one possible implementation, when the uplink transmission of NTN shares the first frequency domain resources with the uplink transmission of TN, the uplink signal of NTN can be transmitted in the form of a supplementary uplink signal or a supplementary uplink (SUL); or, when the downlink transmission of NTN shares the first frequency domain resources with the uplink transmission of TN, the downlink signal of NTN can be transmitted in the form of a supplementary downlink signal or a supplementary downlink (SDL).

[0097] Fig.10 A schematic diagram of a method 1-7 is shown. For example, taking the first frequency domain resource as frequency band F1 and the second frequency domain resource as frequency band F2 as an example, the spectrum resources configured for TN include F1 and F2, F1 is used to transmit NTN uplink signals or downlink signals, and TN uplink signals, and F2 is used to transmit TN downlink signals. NTN uplink signals are transmitted in SUL mode.

[0098] Mode 1-8: Transmitting the uplink signal or downlink signal of the NTN on the second frequency domain resource.

[0099] In this case, NTN downlink transmission and NTN uplink transmission occupy the second frequency domain resources configured for TN, and the first frequency domain resources configured for TN are not shared with NTN. Therefore, the shared frequency domain resources include the second frequency domain resources.

[0100] The uplink transmission or downlink transmission of NTN uses the second frequency domain resources configured for TN, while the first frequency domain resources of TN are only used to transmit the uplink transmission of TN. In this way, since the first frequency domain resources configured for TN are only used to transmit the uplink signal of TN without interference from the signal of NTN, this method can not only improve resource utilization, but also give priority to guaranteeing the quality of uplink transmission of TN, and can be adapted to the scenario where it is necessary to give priority to guaranteeing the uplink transmission of TN.

[0101] In a possible implementation, when the uplink transmission of NTN shares the second frequency domain resources with the downlink transmission of TN, the uplink signal of NTN can be transmitted in SUL mode, and when the downlink transmission of NTN shares the second frequency domain resources with the downlink transmission of TN, the downlink signal of NTN can be transmitted in SDL mode.

[0102] Fig.11 A schematic diagram of a method 1-8 is shown. For example, taking the second frequency domain resource as frequency band F1 and the second frequency domain resource as frequency band F2 as an example, the spectrum resources configured for TN include F1 and F2, F2 is used to transmit NTN uplink signal or downlink signal, and TN downlink signal, and F1 is used to transmit TN uplink signal. NTN uplink signal is transmitted in SUL mode.

[0103] It should be noted that in Modes 1-3 to 1-8, TN shares only one direction with NTN. For example, in Modes 1-3, 1-5 and 1-7, only the first frequency domain resources are shared. In Modes 1-4, 1-6 and 1-8, only the second frequency domain resources are shared.

[0104] Mode 1-9: Transmitting an uplink signal and / or a downlink signal of NTN on a first frequency domain resource, and transmitting an uplink signal and / or a downlink signal of NTN on a second frequency domain resource. For example, transmitting an uplink signal of NTN on a first frequency domain resource and a second frequency domain resource, or transmitting a downlink signal of NTN on a first frequency domain resource and a second frequency domain resource.

[0105] In this case, NTN has only one link to share the transmission resources of TN. In addition, in Modes 1-3 to 1-8, TN has only one transmission direction (or transmission link) to share with NTN.

[0106] The above are nine ways for TN to transmit signals using FDD. When TN transmits signals using TDD, the shared frequency domain resources can be the transmission resources configured for TN, that is, the uplink and downlink transmissions of TN are both transmitted using the same frequency domain resources. The shared frequency domain resources meet any one of methods 1-10 to 1-12. The following is a description of methods 1-10 to 1-12:

[0107] Mode 1-10: Transmitting the uplink signal and downlink signal of NTN on shared frequency domain resources. The uplink signal and downlink signal of NTN are transmitted in TDD mode.

[0108] In this case, NTN downlink transmission and NTN uplink transmission share the transmission resources configured for TN with TN transmission. TN transmission includes TN uplink transmission and downlink transmission.

[0109] When the shared frequency domain resource is a TDD resource, the shared frequency domain resource may be a TDD spectrum resource. For example, the spectrum resources for uplink transmission and downlink transmission of TN are the same, and different time domain resources are used for transmission.

[0110] Fig.12 A schematic diagram of a mode 1-10 is shown. Exemplarily, taking the shared frequency domain resources as TDD resources as an example, the shared frequency domain resources can be used to transmit NTN uplink signals, NTN downlink signals, TN uplink signals and TN downlink signals.

[0111] Mode 1-11: Transmitting the uplink signal and downlink signal of NTN on shared frequency domain resources. The uplink signal and downlink signal of NTN are transmitted in FDD mode.

[0112] In this case, NTN downlink transmission and NTN uplink transmission share the transmission resources configured for TN with TN transmission. TN transmission includes TN uplink transmission and downlink transmission.

[0113] When the shared frequency domain resource is a TDD resource, the shared frequency domain resource may be a TDD spectrum resource. For example, the spectrum resources for uplink transmission and downlink transmission of TN are the same, and different time domain resources are used for transmission.

[0114] Fig.13 A schematic diagram of a mode 1-11 is shown. Exemplarily, taking the shared frequency domain resource as an FDD resource as an example, the shared frequency domain resource can be used to transmit an NTN uplink signal, an NTN downlink signal, a TN uplink signal, and a TN downlink signal.

[0115] Mode 1-12: Transmitting the uplink signal or downlink signal of NTN on the shared frequency domain resources. The uplink signal of NTN is transmitted in the SUL mode; or, the downlink signal of NTN is transmitted in the SDL mode.

[0116] In this case, NTN downlink transmission or NTN uplink transmission shares the transmission resources configured for TN with TN transmission. TN transmission includes TN uplink transmission and TN downlink transmission.

[0117] When the shared frequency domain resource is a TDD resource, the shared frequency domain resource may be a TDD spectrum resource. For example, the spectrum resources for uplink transmission and downlink transmission of TN are the same, and different time domain resources are used for transmission.

[0118] Fig.14 A schematic diagram of a mode 1-12 is shown. Exemplarily, taking the shared frequency domain resources as FDD resources as an example, the shared frequency domain resources can be used to transmit NTN uplink signals, NTN downlink signals, TN uplink signals and TN downlink signals.

[0119] It should be noted that in Modes 1-10 to 1-12, due to the extremely long delay of NTN, a large guard period (GP) is required. Therefore, for NTN, the spectrum efficiency of TDD is poor. Most NTNs communicate in FDD mode, but there are a few low earth orbit satellites (LEO) and high altitude pseudo satellites (HAPS) that can communicate in TDD mode.

[0120] Scenario 2: Target frequency domain resources include resources configured for NTN

[0121] The resources configured for the NTN include transmission resources configured (or allocated) for the NTN, i.e., transmission resources used to transmit NTN signals. The shared frequency domain resources may include frequency domain resources configured for the NTN, and the TN shares the transmission resources of the NTN in a supplementary manner. In this way, nodes in the TN can also send signals on the resources configured for the NTN, thereby improving resource utilization.

[0122] In some embodiments, the frequency domain resources configured for NTN include third frequency domain resources, and / or fourth frequency domain resources. The third frequency domain resources are used to transmit the uplink signal of NTN, that is, the third frequency domain resources are uplink transmission resources (e.g., frequency band F1) for transmitting the uplink NTN signal; the fourth frequency domain resources are used to transmit the downlink signal of NTN, that is, the fourth frequency domain resources are downlink transmission resources (e.g., frequency band F2) for transmitting the downlink NTN signal. For example, NTN transmits uplink NTN signals on frequency band F1 and transmits downlink NTN signals on frequency band F2. It should be understood that at this time, the NTN signal is transmitted in FDD mode.

[0123] It should be noted that in different sharing modes, the shared frequency domain resources include different resources, or the shared frequency domain resources are used to transmit different signal types. The shared frequency domain resources can meet any one of Modes 2-1 to 2-9. The following will describe nine modes of TN sharing resources configured for NTN:

[0124] Mode 2-1: Transmitting the uplink signal of TN on the third frequency domain resources, and transmitting the downlink signal of TN on the fourth frequency domain resources. In this case, the shared frequency domain resources include the third frequency domain resources and the fourth frequency domain resources.

[0125] TN uplink transmission occupies the uplink transmission resources configured for NTN, that is, the third frequency domain resources; TN downlink transmission occupies the downlink transmission resources configured for NTN, that is, the fourth frequency domain resources. In this way, TN signal transmission can occupy the transmission resources configured for NTN, and the shared frequency domain resources are used for the same direction of the transmitted signals (that is, TN uplink and NTN uplink are transmitted on the third frequency domain resources, or TN downlink and NTN downlink are transmitted on the fourth frequency domain resources), which can reduce cross-link interference. In addition, the uplink and downlink resources configured for NTN can be shared with TN, thereby further improving spectrum utilization.

[0126] Fig.15 A schematic diagram of mode 2-1 is shown. Exemplarily, taking the third frequency domain resource as frequency band F1 and the fourth frequency domain resource as frequency band F2 as an example, the shared frequency domain resources include F1 and F2, F1 is used to transmit NTN uplink signals and TN uplink signals, and F2 is used to transmit TN downlink signals and NTN downlink signals.

[0127] Mode 2-2: Transmitting the downlink signal of TN on the third frequency domain resources, and transmitting the uplink signal of TN on the fourth frequency domain resources. In this case, the shared frequency domain resources include the third frequency domain resources and the fourth frequency domain resources.

[0128] TN downlink transmission occupies the uplink transmission resources configured for NTN, that is, the third frequency domain resources; TN uplink transmission occupies NTN downlink transmission resources, that is, the fourth frequency domain resources. In this way, TN transmission occupies NTN's transmission resources, and the shared frequency domain resources are used to transmit signals in opposite directions (that is, TN downlink and NTN uplink are transmitted on the third frequency domain resources, or TN uplink and NTN downlink are transmitted on the fourth frequency domain resources), which can reduce interference from co-directional signals. In addition, both the uplink and downlink resources of NTN can be shared with TN, thereby further improving spectrum utilization.

[0129] Fig.16 A schematic diagram of mode 2-2 is shown. Exemplarily, taking the third frequency domain resource as frequency band F1 and the fourth frequency domain resource as frequency band F2 as an example, the shared frequency domain resources include F1 and F2, F1 is used to transmit NTN uplink signals and TN downlink signals, and F2 is used to transmit TN uplink signals and NTN downlink signals.

[0130] Mode 2-3: Transmitting the uplink signal and downlink signal of TN on the third frequency domain resource. The uplink signal and downlink signal of TN are transmitted in TDD mode.

[0131] In this case, TN downlink transmission and TN uplink transmission occupy the third frequency domain resources configured for NTN, and the fourth frequency domain resources configured for NTN are not shared with TN. Therefore, the shared frequency domain resources include the third frequency domain resources.

[0132] The uplink and downlink transmission of TN both use the third frequency domain resources configured for NTN, while the fourth frequency domain resources configured for NTN are only used for downlink transmission of NTN. In this way, since the fourth frequency domain resources of NTN are only used to transmit the downlink signal of NTN without interference from the signal of TN, this method can not only improve resource utilization, but also give priority to guaranteeing the quality of downlink transmission of NTN, and is suitable for the scenario where it is necessary to give priority to guaranteeing the downlink transmission of NTN.

[0133] Fig.17 A schematic diagram of mode 2-3 is shown. For example, taking the third frequency domain resource as frequency band F1 and the fourth frequency domain resource as frequency band F2 as an example, the spectrum resources configured for NTN include F1 and F2, F1 is used to transmit TN uplink signals and TN downlink signals, as well as NTN uplink signals, and F2 is used to transmit NTN downlink signals. TN uplink signals and downlink signals are transmitted in TDD mode, and the frequency domain resources for transmitting the uplink signals and the downlink signals can overlap.

[0134] Mode 2-4: Transmitting the uplink signal and the downlink signal of TN on the fourth frequency domain resource. The uplink signal and the downlink signal of TN are transmitted in TDD mode.

[0135] In this case, TN downlink transmission and TN uplink transmission occupy the fourth frequency domain resources configured for NTN, and the third frequency domain resources configured for NTN are not shared with TN. Therefore, the shared frequency domain resources include the fourth frequency domain resources.

[0136] Both the uplink and downlink transmissions of TN use the fourth frequency domain resources configured for NTN, while the third frequency domain resources configured for NTN are only used to transmit the uplink transmission of NTN. In this way, since the third frequency domain resources of NTN are only used to transmit the uplink signal of NTN without the interference of the signal of TN, this method can not only improve the resource utilization, but also give priority to the quality of the uplink transmission of NTN, and can be adapted to the scenario where the uplink transmission of NTN needs to be given priority. For example, in some simulation or test scenarios, when NTN and TN share the spectrum, this method can be used when the interference received by the uplink transmission of NTN is relatively serious.

[0137] Fig.18 A schematic diagram of a method 2-4 is shown. For example, taking the third frequency domain resource as frequency band F1 and the fourth frequency domain resource as frequency band F2 as an example, the spectrum resources of NTN include F1 and F2, F1 is used to transmit NTN uplink signals, and F2 is used to transmit TN uplink signals and TN downlink signals, as well as NTN downlink signals. The uplink signal and downlink signal of TN are transmitted in a TDD manner, and the frequency domain resources for transmitting the uplink signal and the downlink signal can overlap.

[0138] Mode 2-5: Transmitting the uplink signal and downlink signal of TN on the third frequency domain resource. The uplink signal and downlink signal of TN are transmitted in FDD mode.

[0139] In this case, TN downlink transmission and TN uplink transmission occupy the third frequency domain resources configured for NTN, and the fourth frequency domain resources configured for NTN are not shared with TN. Therefore, the shared frequency domain resources include the third frequency domain resources.

[0140] The uplink and downlink transmission of TN both use the third frequency domain resources configured for NTN, while the fourth frequency domain resources configured for NTN are only used for downlink transmission of NTN. In this way, since the fourth frequency domain resources of NTN are only used to transmit the downlink signal of NTN without interference from the signal of TN, this method can not only improve resource utilization, but also give priority to guaranteeing the quality of downlink transmission of NTN, and is suitable for the scenario where it is necessary to give priority to guaranteeing the downlink transmission of NTN.

[0141] Fig.19A schematic diagram of a method 2-5 is shown. Exemplarily, taking the third frequency domain resource as frequency band F1 and the fourth frequency domain resource as frequency band F2 as an example, the spectrum resources configured for NTN include F1 and F2, F1 is used to transmit TN uplink signals and TN downlink signals, as well as NTN uplink signals, and F2 is used to transmit NTN downlink signals. The uplink signal and downlink signal of TN are transmitted in an FDD manner, and the time domain resources for transmitting the uplink signal and the downlink signal can overlap. For example, frequency band F1 includes frequency band F1-1 and frequency band F1-2, frequency band F1-1 is used to transmit the uplink signal of TN, and frequency band F1-2 is used to transmit the downlink signal of TN.

[0142] Mode 2-6: Transmitting the uplink signal and the downlink signal of TN on the fourth frequency domain resource. The uplink signal and the downlink signal of TN are transmitted in FDD mode.

[0143] In this case, TN downlink transmission and TN uplink transmission occupy the fourth frequency domain resources configured for NTN, and the third frequency domain resources configured for NTN are not shared with TN. Therefore, the shared frequency domain resources include the fourth frequency domain resources.

[0144] Both the uplink and downlink transmissions of TN use the fourth frequency domain resources configured for NTN, while the third frequency domain resources configured for NTN are only used to transmit the uplink transmission of NTN. In this way, since the third frequency domain resources of NTN are only used to transmit the uplink signal of NTN without the interference of the signal of TN, this method can not only improve the resource utilization, but also give priority to the quality of the uplink transmission of NTN, and can be adapted to the scenario where the uplink transmission of NTN needs to be given priority. For example, in some simulation or test scenarios, when NTN and TN share the spectrum, this method can be used when the interference received by the uplink transmission of NTN is relatively serious.

[0145] Fig. 20 A schematic diagram of a method 2-6 is shown. Exemplarily, taking the third frequency domain resource as frequency band F1 and the fourth frequency domain resource as frequency band F2 as an example, the spectrum resources configured for NTN include F1 and F2, F1 is used to transmit NTN uplink signals, and F2 is used to transmit TN uplink signals and TN downlink signals, as well as NTN downlink signals. The uplink signal and downlink signal of TN are transmitted in an FDD manner, and the time domain resources for transmitting the uplink signal and the downlink signal can overlap. For example, frequency band F2 includes frequency band F2-1 and frequency band F2-2, frequency band F2-1 is used to transmit the uplink signal of TN, and frequency band F2-2 is used to transmit the downlink signal of TN.

[0146] Method 2-7: Transmit the uplink signal or downlink signal of TN on the third frequency domain resource.

[0147] In this case, TN downlink transmission or TN uplink transmission occupies the third frequency domain resources configured for NTN, and the fourth frequency domain resources configured for NTN are not shared with TN. Therefore, the shared frequency domain resources include the third frequency domain resources.

[0148] The uplink transmission or downlink transmission of TN shares the third frequency domain resources of NTN, while the fourth frequency domain resources of NTN are only used to transmit the downlink transmission of NTN. In this way, since the fourth frequency domain resources of NTN are only used to transmit the downlink signal of NTN without the interference of the signal of TN, this method can not only improve the resource utilization rate, but also give priority to the quality of the downlink transmission of NTN, which can be adapted to the scenario where the downlink transmission of NTN needs to be given priority.

[0149] In a possible implementation, when the uplink transmission of TN shares the third frequency domain resources with the uplink transmission of NTN, the SUL mode can be used for transmission; or, when the downlink transmission of TN shares the third frequency domain resources with the uplink transmission of NTN, the SDL mode can be used for transmission.

[0150] Fig.21 A schematic diagram of a method 2-7 is shown. For example, taking the third frequency domain resource as frequency band F1 and the fourth frequency domain resource as frequency band F2 as an example, the spectrum resources configured for NTN include F1 and F2, F1 is used to transmit TN uplink signals or downlink signals, and NTN uplink signals, and F2 is used to transmit NTN downlink signals. TN uplink signals are transmitted in SUL mode.

[0151] Method 2-8: Transmit the uplink signal or downlink signal of TN on the fourth frequency domain resources.

[0152] In this case, TN downlink transmission and TN uplink transmission occupy the fourth frequency domain resources configured for NTN, and the third frequency domain resources configured for NTN are not shared with TN. Therefore, the shared frequency domain resources include the fourth frequency domain resources.

[0153] The uplink transmission or downlink transmission of TN uses the fourth frequency domain resources configured for NTN, while the third frequency domain resources of NTN are only used for uplink transmission of NTN. In this way, since the third frequency domain resources configured for NTN are only used for uplink transmission of NTN without interference from TN signals, this method can not only improve resource utilization, but also give priority to guaranteeing the quality of uplink transmission of NTN, and can be adapted to the scenario where uplink transmission of NTN needs to be given priority.

[0154] In a possible implementation, when TN's uplink transmission shares the fourth frequency domain resources with NTN's downlink transmission, it can be transmitted in SUL mode, and when TN's downlink transmission shares the fourth frequency domain resources with NTN's downlink transmission, it can be transmitted in SDL mode.

[0155] Fig. 22 A schematic diagram of a method 2-8 is shown. For example, taking the fourth frequency domain resource as frequency band F1 and the fourth frequency domain resource as frequency band F2 as an example, the spectrum resources configured for NTN include F1 and F2, F2 is used to transmit TN uplink signals or downlink signals, and NTN downlink signals, and F2 is used to transmit NTN uplink signals. TN uplink signals are transmitted in SUL mode.

[0156] It should be noted that in Modes 2-3 to 2-8, NTN shares with TN in only one direction. For example, in Modes 2-3, 2-5 and 2-7, only the third frequency domain resources are shared. In Modes 2-4, 2-6 and 2-8, only the fourth frequency domain resources are shared.

[0157] Mode 2-9: Transmitting the uplink signal and / or downlink signal of TN on the third frequency domain resources, and transmitting the uplink signal and / or downlink signal of TN on the fourth frequency domain resources. For example, transmitting the uplink signal of TN on the third frequency domain resources and the fourth frequency domain resources, or transmitting the downlink signal of TN on the third frequency domain resources and the fourth frequency domain resources.

[0158] In this case, TN has only one link to share the transmission resources of NTN. In addition, in Modes 2-1 to 2-8, NTN has only one transmission direction (or transmission link) to share with TN.

[0159] The above are nine ways for NTN to transmit signals using FDD. When NTN transmits signals using TDD, the shared frequency domain resources can be transmission resources configured for NTN, that is, both the uplink and downlink transmissions of NTN use the same frequency domain resources for transmission. The shared frequency domain resources meet any one of Methods 2-10 to 2-12. The following is a description of Methods 2-10 to 2-12:

[0160] Mode 2-10: Transmitting the uplink signal and downlink signal of TN on shared frequency domain resources. The uplink signal and downlink signal of TN are transmitted in TDD mode.

[0161] In this case, TN downlink transmission and TN uplink transmission share the transmission resources configured for NTN with NTN transmission. NTN transmission includes NTN uplink transmission and NTN downlink transmission.

[0162] When the shared frequency domain resource is a TDD resource, the shared frequency domain resource may be a TDD spectrum resource. For example, the spectrum resources for uplink transmission and downlink transmission of NTN are the same, and different time domain resources are used for transmission.

[0163] Fig.23A schematic diagram of a mode 2-10 is shown. Exemplarily, taking the shared frequency domain resource as a TDD resource as an example, the shared frequency domain resource can be used to transmit a TN uplink signal, a TN downlink signal, an NTN uplink signal, and an NTN downlink signal.

[0164] Mode 2-11: Transmitting the uplink signal and downlink signal of TN on shared frequency domain resources. The uplink signal and downlink signal of TN are transmitted in FDD mode.

[0165] In this case, TN downlink transmission and TN uplink transmission share the transmission resources configured for NTN with NTN transmission. NTN transmission includes NTN uplink transmission and NTN downlink transmission.

[0166] When the shared frequency domain resource is a TDD resource, the shared frequency domain resource may be a TDD spectrum resource. For example, the spectrum resources for uplink transmission and downlink transmission of NTN are the same, and different time domain resources are used for transmission.

[0167] Fig.24 A schematic diagram of a mode 2-11 is shown. Exemplarily, taking the shared frequency domain resource as an FDD resource as an example, the shared frequency domain resource can be used to transmit a TN uplink signal, a TN downlink signal, an NTN uplink signal, and an NTN downlink signal.

[0168] Mode 2-12: Transmitting the uplink signal or downlink signal of the TN on the shared frequency domain resources. The uplink signal of the TN is transmitted in the SUL mode; or, the downlink signal of the TN is transmitted in the SDL mode.

[0169] In this case, the TN downlink transmission or the TN uplink transmission shares the transmission resources configured for the NTN with the NTN transmission. The NTN transmission includes the NTN uplink transmission and the NTN downlink transmission.

[0170] When the shared frequency domain resource is a TDD resource, the shared frequency domain resource may be a TDD spectrum resource. For example, the spectrum resources for uplink transmission and downlink transmission of NTN are the same, and different time domain resources are used for transmission.

[0171] Fig.25 A schematic diagram of a mode 2-12 is shown. Exemplarily, taking the shared frequency domain resource as an FDD resource as an example, the shared frequency domain resource can be used to transmit a TN uplink signal, a TN downlink signal, an NTN uplink signal, and an NTN downlink signal.

[0172] Scenario 3: Target frequency domain resources include frequency domain resources configured for NTN and TN

[0173] The frequency domain resources configured for NTN and TN can be any frequency domain resources, rather than transmission resources configured for NTN or TN. NTN and TN can use the shared frequency domain resources together in a fair or agreed manner (based on rules or collaboration). In this way, both TN and NTN can transmit signals through the shared frequency domain resources without allocating transmission resources for NTN and TN, thereby saving transmission resources and improving resource utilization.

[0174] It should be noted that in different sharing modes, the shared frequency domain resources include different resources, or the shared frequency domain resources are used to transmit different signal types. The shared frequency domain resources can meet any one of Modes 3-1 to 3-10. The following will describe nine modes for TN and NTN to share the shared frequency domain resources (it should be understood that the difference between scenario three and scenarios one and two is that the shared frequency domain resources are resources to whom they are configured. The following will give the corresponding relationship between the modes in scenario three and the modes in scenarios one and two):

[0175] Mode 3-1: Shared frequency domain resources are used to transmit TN uplink signals and / or downlink signals, as well as NTN uplink signals. NTN downlink transmission does not share resources with TN transmission.

[0176] For example, the TN uplink signal and the downlink signal may be transmitted on shared frequency domain resources in a TDD manner, corresponding to method 2-3.

[0177] Alternatively, the TN uplink signal and downlink signal may be transmitted on shared frequency domain resources in an FDD manner, corresponding to method 2-5.

[0178] Alternatively, the uplink signal or downlink signal of TN is transmitted on shared frequency domain resources with the uplink signal of NTN, and the uplink signal of TN can be transmitted in SUL mode, and the downlink signal of TN can be transmitted in SDL mode, corresponding to mode 2-7.

[0179] Mode 3-2: Shared frequency domain resources are used to transmit TN uplink signals and / or downlink signals, as well as NTN downlink signals. NTN uplink transmission does not share resources with TN transmission.

[0180] For example, the TN uplink signal and the downlink signal may be transmitted on shared frequency domain resources in a TDD manner, corresponding to methods 2-4.

[0181] Alternatively, the TN uplink signal and downlink signal may be transmitted on shared frequency domain resources in an FDD manner, corresponding to method 2-6.

[0182] Alternatively, the TN uplink signal or downlink signal, and the NTN downlink signal are transmitted on shared frequency domain resources, and the TN uplink signal can be transmitted in SUL mode, and the TN downlink signal can be transmitted in SDL mode, corresponding to mode 2-8.

[0183] Mode 3-3: Shared frequency domain resources are used to transmit the uplink signal or downlink signal of TN, and the uplink signal and downlink signal of NTN.

[0184] For example, the uplink signal or downlink signal of TN and the signal of NTN (including uplink signal and downlink signal) are transmitted on shared frequency domain resources, corresponding to mode 2-9.

[0185] Mode 3-4: Shared frequency domain resources are used to transmit the uplink signal of NTN and / or the downlink signal, as well as the uplink signal of TN. The downlink transmission of TN does not share resources with the transmission of NTN.

[0186] For example, the uplink signal and downlink signal of the NTN may be transmitted on shared frequency domain resources in a TDD manner, corresponding to manners 1-3.

[0187] Alternatively, the uplink signal and downlink signal of the NTN may be transmitted on shared frequency domain resources in an FDD manner, corresponding to manners 1-5.

[0188] Alternatively, the NTN uplink signal or downlink signal is transmitted on a shared frequency domain resource with the TN uplink signal, and the TN uplink signal can be transmitted in SUL mode, and the TN downlink signal can be transmitted in SDL mode, corresponding to mode 1-7.

[0189] Mode 3-5: Shared frequency domain resources are used to transmit uplink signals and / or downlink signals of NTN and downlink signals of TN. Uplink transmission of TN and NTN transmission do not share resources.

[0190] For example, NTN uplink signals and downlink signals may be transmitted on shared frequency domain resources in a TDD manner, corresponding to manners 1-4.

[0191] Alternatively, the uplink signal and downlink signal of the NTN may be transmitted on shared frequency domain resources in an FDD manner, corresponding to manner 1-6.

[0192] Alternatively, the uplink signal or downlink signal of NTN is transmitted on a shared frequency domain resource with the downlink signal of TN, and the uplink signal of TN can be transmitted in SUL mode, and the downlink signal of TN can be transmitted in SDL mode, corresponding to mode 1-8.

[0193] Mode 3-6: shared frequency domain resources are used to transmit uplink signals or downlink signals of NTN, as well as uplink signals and downlink signals of TN, corresponding to mode 2-9.

[0194] Mode 3-7: When the shared frequency domain resources include the fifth frequency domain resources and the sixth frequency domain resources, the fifth frequency domain resources are used to transmit the uplink signal of TN and the uplink signal of NTN, and the sixth frequency domain resources are used to transmit the downlink signal of TN and the downlink signal of NTN.

[0195] The shared frequency domain resources can be divided into multiple frequency domain resources for transmission separately. When the shared frequency domain resources include the fifth frequency domain resources and the sixth frequency domain resources, the fifth frequency domain resources can be transmission resources for transmitting the uplink signal of TN and the uplink signal of NTN, and the sixth frequency domain resources can be transmission resources for transmitting the downlink signal of TN and the downlink signal of NTN, corresponding to method 1-1 and method 2-1.

[0196] Mode 3-8: When the shared frequency domain resources include the fifth frequency domain resources and the sixth frequency domain resources, the fifth frequency domain resources are used to transmit the uplink signal of TN and the downlink signal of NTN, and the sixth frequency domain resources are used to transmit the downlink signal of TN and the uplink signal of NTN.

[0197] The shared frequency domain resources can be divided into multiple frequency domain resources for transmission separately. When the shared frequency domain resources include the fifth frequency domain resources and the sixth frequency domain resources, the fifth frequency domain resources can be the transmission resources for transmitting the uplink signal of TN and the downlink signal of NTN, and the sixth frequency domain resources can be the transmission resources for transmitting the downlink signal of TN and the uplink signal of NTN, corresponding to method 1-2 and method 2-2.

[0198] Mode 3-9: Transmit the uplink signal and / or downlink signal of NTN, and the uplink signal and downlink signal of TN on shared frequency domain resources.

[0199] For example, the uplink signal and downlink signal of the NTN may be transmitted on shared frequency domain resources in a TDD manner, corresponding to manners 1-10.

[0200] Alternatively, the uplink signal and downlink signal of the NTN may be transmitted on shared frequency domain resources in an FDD manner, corresponding to manner 1-11.

[0201] Alternatively, the uplink signal or downlink signal of NTN is transmitted on shared frequency domain resources with the uplink signal and downlink signal of TN, and the uplink signal of NTN can be transmitted in SUL mode, and the downlink signal of NTN can be transmitted in SDL mode, corresponding to mode 1-12.

[0202] Mode 3-10: Transmitting the uplink signal and / or downlink signal of TN, and the uplink signal and downlink signal of NTN on shared frequency domain resources.

[0203] For example, the uplink signal and downlink signal of TN can be transmitted on shared frequency domain resources in TDD mode, corresponding to mode 2-10.

[0204] Alternatively, the uplink signal and downlink signal of TN can be transmitted on shared frequency domain resources in FDD mode, corresponding to mode 2-11.

[0205] Alternatively, the uplink signal of TN can be transmitted in SUL mode, and the downlink signal of TN can be transmitted in SDL mode, corresponding to mode 2-12.

[0206] In addition, before the first node transmits NTN signals and TN signals through shared frequency domain resources, it is necessary to indicate the configuration information of the shared frequency domain resources to NTN or TN or instruct NTN or TN to switch the sharing mode. The configuration information may include at least one of the following: the scenario of shared frequency domain resources, the sharing mode, and the parameters of shared frequency domain resources.

[0207] Among them, the scenario of shared frequency domain resources is the scenario in which the signal is transmitted in a shared manner. The sharing mode is the type of shared frequency domain resources (for example, the first frequency domain resources or the third frequency domain resources) or the type of signal used for transmission by the shared frequency domain resources. The parameters of shared frequency domain resources include at least one of the following: configuration information of specific signals on shared frequency domain resources (for example, physical uplink control channel (PUCCH), sounding reference signal (SRS)), initial bandwidth part BWP configuration information, BWP sequence number, RB set sequence number, subband sequence number, conditions for using shared frequency domain resources, starting time of sharing, effective duration of sharing, and whether the shared frequency domain resources are TDD resources or FDD resources.

[0208] The following describes various methods of indicating the configuration information of the shared frequency domain resources to the TN or NTN through methods 4-1 to 4-7 respectively:

[0209] Mode 4-1: The network or system (such as spectrum access system, spectrum management system, etc.) is configured to the base station and terminal of TN or NTN. The spectrum access system or spectrum management system is responsible for managing the resource sharing between TN and NTN, such as determining the sharing mode, that is, determining which resources the shared frequency domain resources include or determining which types of signals the shared frequency domain resources are used to transmit (such as the uplink signal of NTN and the uplink signal of TN), or dynamically allocating spectrum resources, or performing interference coordination. The system can be an independent node or entity, or it can be integrated in a TN base station or NTN base station (i.e., a satellite).

[0210] Mode 4-2: The core network / operation administration and maintenance (OAM) indicates the configuration information of the shared frequency domain resources to the TN base station or the NTN base station.

[0211] Mode 4-3, the configuration information of shared frequency domain resources is determined between NTN (e.g., NTN base station) and TN (e.g., TN base station). For example, the NTN base station sends a sharing request message to the TN base station. The TN base station indicates to the NTN base station / satellite the scenario for determining shared frequency domain resources, the sharing method, and / or the parameters of shared frequency domain resources. Afterwards, the NTN base station may feedback a confirmation message to the TN base station. The above steps are not indispensable and may be performed individually or in combination. Optionally, a sharing request message may be initiated by a network that wishes to share a spectrum and sent to the network whose spectrum is shared. For example, in the case where NTN shares the frequency domain resources configured for TN, the NTN base station may send a sharing request message to the TN base station.

[0212] Mode 4-4: The base station or network (e.g., TN base station or NTN base station) transmits the information to the base station through system information (e.g., synchronization signal block (SSB), master information block (MIB), system information block (SIB) 1, SIB19 or other system information blocks), radio resource control signaling.

[0213] (Radio resource control signaling, RRC) signaling, medium access control control element (medium access control control element, MAC CE), downlink control information (downlink control information, DCI) signaling and other configurations or instructions are given to the terminal.

[0214] Mode 4-5: The first network (e.g., a base station) determines the configuration information of the shared frequency domain resources and indicates it to the second network (e.g., a base station). The first network is the network of the shared resources, and the second network is the network of the shared resources. For example, in the case where the shared frequency domain resources include spectrum resources configured to the NTN, the NTN is the network of the shared resources, and the TN is the network of the shared resources.

[0215] Mode 4-6: The first node receives a switching indication message, and switches the type of shared frequency domain resources or the type of signals used for transmission of shared frequency domain resources based on the switching indication message. For example, the NTN base station / satellite may send a switching indication message to the TN base station, thereby instructing the TN base station to switch the sharing mode; or, the TN base station may send a switching indication message to the NTN base station / satellite, thereby instructing the NTN base station / satellite to switch the sharing mode; or, the terminal may send a switching indication message to the NTN base station, satellite or TN base station, thereby instructing the NTN satellite or TN base station to switch the sharing mode; or, the NTN base station / satellite or TN base station sends a switching indication message to the terminal, thereby causing the terminal to switch the sharing mode. Optionally, the switching indication message may include a measurement result.

[0216] In a possible implementation, the NTN base station / satellite may receive the measurement results reported by the NTN terminal. When the NTN base station / satellite determines that the signal quality parameter (or channel quality parameter) is lower than the preset parameter based on the measurement results, it may be determined that the signal quality is poor. Therefore, in the case where the NTN base station / satellite supports multiple sharing modes, the NTN base station / satellite may determine that the sharing mode needs to be switched (for example, from mode 1-1 to mode 1-2), that is, the type of shared frequency domain resources or the type of signals used for transmission of the shared frequency domain resources is switched, for example, the first frequency domain resources in mode 1-3 are switched to the second frequency domain resources in mode 1-4, or the first frequency domain resources in mode 1-3 are used to transmit the uplink signal and downlink signal of the NTN, and are switched to the first frequency domain resources in mode 1-7 for transmitting the uplink signal or downlink signal of the NTN. In addition, after the NTN base station / satellite switches the sharing mode, second information may be sent to the NTN terminal to instruct the NTN terminal to switch the sharing mode to the sharing mode switched by the NTN base station.

[0217] It should be noted that the NTN base station / satellite can determine the switching sharing mode based on the switching indication message reported by the NTN terminal, and can also determine the switching sharing mode based on the switching indication message from the TN base station. For example, in the case where the shared frequency domain resource is a transmission resource configured for the NTN, the NTN base station / satellite can send a switching indication message to the TN base station, thereby instructing or requesting the TN base station to switch the sharing mode through the switching indication message, or applying to the TN base station for information on switching the sharing mode.

[0218] In another possible implementation, NTN and TN may adopt a resource sharing mode (e.g., mode 3-1) by default. When the interference parameter of the signal is greater than the preset parameter value (or the signal quality parameter is less than the preset parameter value), NTN and TN switch the resource sharing mode (e.g., mode 3-2) to reduce interference. If NTN and TN support two sharing modes, one bit may be used to determine whether to switch, for example, bit 0 is used to indicate the first sharing mode, and bit 1 is used to indicate the second sharing mode. If NTN and TN support more than two sharing modes, the switching of sharing modes may be indicated by a variety of methods such as bitmaps, indexes, and enumerations.

[0219] Mode 4-7: The terminal sends a switching request message to the base station (or satellite), and / or the base station (or satellite) sends a switching request confirmation message to the terminal.

[0220] The terminal can send a switching request message of the sharing mode to the base station or satellite through the dynamic changes of measurement results or topology (such as measurement, ephemeris and other information). The switching request message can be carried by PUCCH, physical uplink shared channel (physical uplink shared channel, PUSCH), uplink reference signal, and signal / channel sequence. Based on the request message, the base station or satellite can feedback a switching request confirmation message to the terminal. The switching request confirmation message may include any of the following: switching is allowed, switching is not allowed, and the terminal decides by itself. The base station or satellite can also directly indicate or configure the sharing mode based on the request message.

[0221] For example, Fig.26 FIG. 1 shows a schematic diagram of the structure of various modes in a signal transmission method. Fig.26 As shown, the method provided by the embodiment of the present disclosure includes scenarios 1 to 4. Among them, scenario 4 is to indicate the configuration information of the shared frequency domain resources and the switching of the sharing mode. Scenario 1 includes mode 1-1 to mode 1-12, scenario 2 includes mode 2-1 to mode 2-12, scenario 3 includes mode 3-1 to mode 3-10, and scenario 4 includes mode 4-1 to mode 4-7.
