[0041] In the following, the technical solutions according to the embodiments of the present disclosure will be described clearly and completely in connection with the drawings in the present disclosure. Apparently, the described embodiments are only part of the embodiments of the present disclosure, rather than all the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by a person of ordinary skill in the art without creative effort shall fall within the protection scope of the present disclosure.

[0042] It should be noted that in the present disclosure, the expressions such as “exemplarily” or “for example” are used to represent as an example, illustration or description. Any embodiment or design scheme described as “exemplarily” or “for example” in the present disclosure should not be interpreted as more preferred or more advantageous than other embodiments or design schemes. In fact, the expressions such as “exemplarily” or “for example” are intended to present the related concept in an exemplary manner.

[0043] In the following, the terms “first”, “second”, and the like are only used for description purposes, and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined with “first”, “second”, and the like can explicitly or implicitly include one or more of the features.

[0044] In the description of the present disclosure, unless otherwise specified, “ / ” represents the meaning of “or”, for example, A / B can represent A or B. “And / or” in the present disclosure only describes the association relationship of the associated objects, which means that there can be three kinds of relationships, for example, A and / or B can represent: only A, only B, and A and B. In addition, “at least one” means one or more, and “multiple” means two or more than two.

[0045] First type of communication: the user communicates by connecting with the first type of device / entity. For example, the first type of communication is TN, and the user communicates by connecting with the base station directly.

[0046] Second type of communication: the user communicates by connecting with the second type of device / entity. For example, the second type of communication is NTN, and the user communicates by connecting with the satellite.

[0047] In the following, the method of spectrum sharing between the first type of communication and the second type of communication will be described by taking TN / NTN as an example of the first / second type of communication. The first / second type of communication can also include communication types other than TN / NTN.

[0048] I. NTN

[0049] The NTN can also be referred to as a satellite network, and mainly refers to a communication network based on non-ground infrastructure. In the NTN, a satellite, an unmanned aerial vehicle (UAV), and a high altitude platform (HAP) can be regarded as a base station, or can be regarded as a relay between a ground base station / gateway and a terminal. The terminal can be connected to the satellite, and thus communication can be implemented through the satellite. In an area where a ground base station cannot directly cover, the terminal can be connected to the satellite for communication, so that full coverage of connection can be achieved.

[0050] FIG. 1 shows a structural schematic diagram of an NTN. Exemplarily, a satellite 101 can be regarded as a base station, so as to be connected to a terminal 102 on the ground in communication, and a link between the satellite 101 and the terminal 102 is a service link. In addition, the satellite 101 is connected to an access network device 103 in communication, and a link between the satellite 101 and the access network device 103 is a feeder link. The satellite 101 is common to all terminals in the same cell. The access network device 103 includes a base station and a gateway.

[0051] II. TN

[0052] The TN mainly refers to a communication network based on ground infrastructure. They provide communication services through ground base stations, antennas, wireless / wired transmission devices, such as a third generation mobile communication technology (3G) universal mobile telecommunications system (UMTS) and a fourth generation mobile communication technology (4G) long term evolution (LTE), which belong to TN networks. It should be understood that a fifth generation mobile communication technology (5G) new radio (NR) network can support both TN and NTN. Future mobile communication technologies, including the sixth generation mobile communication technology (6G), are expected to continue to support TN and NTN.

[0053] III. Spectrum resources

[0054] In wireless communication, spectrum resource is a very important transmission resource, and is the key to the smooth operation of a wireless communication system. For example, NTN (also known as satellite network) and TN are allocated with dedicated spectrum resources. However, spectrum resources are limited, and with the rapid development of wireless communication technology, available spectrum resources are increasingly exhausted. Therefore, how to improve the utilization rate of spectrum resources is a technical problem to be solved at present.

[0055] To solve the above technical problems, the embodiments of the present disclosure provide a signal transmission method, which can transmit signals of a first type of communication and signals of a second type of communication on a target frequency domain resource. In this way, the signals of the first type of communication and the signals of the second type of communication are transmitted on the same frequency domain resource, 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.

[0056] The signal transmission method provided by the embodiments of the present disclosure can be applied to a communication system as shown in FIG. 2. As shown in FIG. 2, the communication system includes a first node 201 and a second node 202.

[0057] The first node 201 and the second node 202 are communicatively connected. The first node 201 can be a base station, a satellite, a terminal, etc. The second node 202 can 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 can be a base station (or a ground communication base station) or a satellite. When the first node 201 is a base station or a satellite, the second node 202 can be a terminal. It should be understood that the satellite in the NTN can also be understood as an NTN base station.

[0058] In the embodiments of the present disclosure, the first node 201 can transmit signals of a terrestrial communication network and signals of a non-terrestrial communication network on a target frequency domain resource. Correspondingly, when the second node 202 is a satellite, the second node 202 can receive the signals of the non-terrestrial communication network sent by the first node 201 on the target frequency domain resource. Alternatively, when the second node 202 is a base station, the second node 202 can receive the signals of the terrestrial communication network sent by the first node 201 on the target frequency domain resource.

[0059] It should be noted that FIG. 2 is only an exemplary block diagram, and the number of devices included in FIG. 2 and the names of the devices are not limited. In addition to the devices shown in FIG. 2, the communication system can also include other devices, such as a relay node.

[0060] 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 used to more clearly illustrate the technical solutions of the present disclosure, and do not constitute a limitation on the technical solutions provided by the present disclosure. It can be known by those skilled in the art that, with the evolution of network architecture and the appearance of new business scenarios, the technical solutions provided by the present disclosure are also applicable to similar technical problems.

[0061] The signal transmission method provided by the embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings.

[0062] The signal transmission method provided by the embodiments of the present disclosure can be applied to the first node 201 in the communication system shown in FIG. 2. FIG. 3 shows a flowchart of a signal transmission method, as shown in FIG. 3, the signal transmission method comprises S301.

[0063] S301, the first node transmits signals of the first type of communication and signals of the second type of communication on the target frequency domain resource.

[0064] In the embodiments of the present disclosure, the first type of communication is taken as a terrestrial communication network, and the second type of communication is taken as a non-terrestrial communication network as an example for description.

[0065] The shared frequency domain resource shared by the terrestrial communication network (hereinafter referred to as TN) and the non-terrestrial communication network (hereinafter referred to as NTN) can include at least one of the following: bandwidth part (bandwidth part, BWP); resource block (resource block, RB); resource block group (or set) (RB group / set); sub-band (sub band); band (band); carrier (carrier); channel (channel). In addition, the TN and the NTN can also share the time domain resource, which can include at least one of the following: symbol; symbol; time slot; subframe; frame. In an implementation manner, 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 the target frequency domain resource can be any frequency domain resource. Hereinafter, the target frequency domain resource is taken as an example for description.

[0066] On the shared frequency domain resource, the first node can transmit TN signals or NTN signals, that is, the shared frequency domain resource is a transmission resource shared by TN and NTN. In this way, transmission resources do not need to be configured for TN and NTN respectively, thereby improving the utilization rate of frequency spectrum resources. In addition, the terminal can connect TN and NTN, for example, when the TN transmission quality decreases, the terminal transmits the NTN signal through the shared frequency domain resource, thereby improving the experience of user full connection.

[0067] In an implementation manner, since the dedicated transmission resources (or frequency domain resources, spectrum resources, etc.) are respectively allocated to the NTN and the TN in an exclusive manner, i.e., the transmission resources of the NTN can only transmit the NTN signals and cannot transmit the TN signals, and correspondingly, the transmission resources of the TN can only transmit the TN signals and cannot transmit the NTN signals. Therefore, when the TN signals and the NTN signals are transmitted through the shared frequency domain resources, the following scenarios one to three can be included:

[0068] Scenario one, the target frequency domain resources include the frequency domain resources configured to the TN

[0069] The resources configured to the TN include the transmission resources configured to the TN, i.e., the transmission resources for transmitting the TN signals. The shared frequency domain resources can include the frequency domain resources configured to the TN, and the NTN shares the transmission resources of the TN in a supplementary manner. In this way, the first node can also send signals on the resources configured to the TN when connecting the NTN, so that there is no need to configure special frequency domain resources for the NTN, thereby saving the frequency domain resources and improving the resource utilization.

[0070] In some embodiments, the frequency domain resources configured to the TN include first frequency domain resources and / or second frequency domain resources. The first frequency domain resources are used for transmitting the uplink (UL) signals of the TN, i.e., the first frequency domain resources are uplink transmission resources (such as frequency band F1) for transmitting the uplink TN signals; and the second frequency domain resources are used for transmitting the downlink (DL) signals of the TN, i.e., the second frequency domain resources are downlink transmission resources (such as frequency band F2) for transmitting the downlink TN signals. For example, the TN transmits the uplink TN signals on the frequency band F1 and transmits the downlink TN signals on the frequency band F2. It should be understood that at this time, the TN signals are transmitted in a frequency division multiplexing or frequency division duplex (FDD) manner, and the shared frequency domain resources are FDD resources or FDD spectrum.

[0071] It should be noted that in different sharing manners, the shared frequency domain resources include different resources or are used for transmitting different types of signals. The shared frequency domain resources can satisfy any one of modes 1-1 to 1-9, and the following will describe nine modes of the NTN sharing the resources configured to the TN:

[0072] Mode 1-1, transmitting the NTN uplink signals on the first frequency domain resources and transmitting the NTN downlink signals on the second frequency domain resources. In this case, the shared frequency domain resources include the first frequency domain resources and the second frequency domain resources.

[0073] The uplink transmission of the NTN occupies the uplink transmission resource configured for the TN, i.e., the first frequency domain resource; and the downlink transmission of the NTN occupies the downlink transmission resource configured for the TN, i.e., the second frequency domain resource. In this way, the signal transmission of the NTN can occupy the transmission resource configured for the TN, and the shared frequency domain resource is used for signals in the same direction (i.e., the TN uplink signal and the NTN uplink signal are transmitted on the first frequency domain resource, or the NTN downlink signal and the TN downlink signal are transmitted on the second frequency domain resource), so as to reduce the interference across the links. In addition, both the uplink and downlink resources configured for the TN can be shared for the NTN, so as to further improve the spectrum utilization.

[0074] FIG. 4 shows a schematic diagram of a manner 1-1. Exemplarily, taking the first frequency domain resource as a frequency band F1 and the second frequency domain resource as a frequency band F2 as an example, the shared frequency domain resource includes F1 and F2, F1 is used for transmitting the TN uplink signal and the NTN uplink signal, and F2 is used for transmitting the NTN downlink signal and the TN downlink signal.

[0075] Manner 1-2, transmitting the NTN downlink signal on the first frequency domain resource and transmitting the NTN uplink signal 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.

[0076] The downlink transmission of the NTN occupies the uplink transmission resource configured for the TN, i.e., the first frequency domain resource; and the uplink transmission of the NTN occupies the downlink transmission resource of the TN, i.e., the second frequency domain resource. In this way, the NTN transmission occupies the transmission resource configured for the TN, and the shared frequency domain resource is used for signals in opposite directions (i.e., the NTN downlink signal and the TN uplink signal are transmitted on the first frequency domain resource, or the NTN uplink signal and the TN downlink signal are transmitted on the second frequency domain resource), so as to reduce the interference from the signals in the same direction. In addition, both the uplink and downlink resources of the TN can be shared for the NTN, so as to further improve the spectrum utilization.

[0077] FIG. 5 shows a schematic diagram of a manner 1-2. Exemplarily, taking the first frequency domain resource as a frequency band F1 and the second frequency domain resource as a frequency band F2 as an example, the shared frequency domain resource includes F1 and F2, F1 is used for transmitting the TN uplink signal and the NTN downlink signal, and F2 is used for transmitting the NTN uplink signal and the TN downlink signal.

[0078] Manner 1-3, transmitting the NTN uplink signal and the NTN downlink signal on the first frequency domain resource. The NTN uplink signal and the NTN downlink signal are transmitted in a time division multiplexing or time division duplex (TDD) manner.

[0079] In this case, the downlink transmission of the NTN and the uplink transmission of the NTN occupy the first frequency domain resource configured for the TN, and the second frequency domain resource configured for the TN is not shared with the NTN, and thus the shared frequency domain resource includes the first frequency domain resource.

[0080] The uplink transmission and the downlink transmission of the NTN both use the first frequency domain resource configured for the TN, and the second frequency domain resource configured for the TN is only used for the downlink transmission of the TN. In this way, since the second frequency domain resource of the TN is only used for transmitting the TN downlink signal without the interference of the NTN signal, this mode not only can improve the resource utilization, but also can preferentially guarantee the quality of the downlink transmission of the TN, and is applicable to a scenario in which the downlink transmission of the TN needs to be preferentially guaranteed.

[0081] FIG. 6 shows a schematic diagram of a mode 1-3. Exemplarily, taking the first frequency domain resource as a frequency band F1 and the second frequency domain resource as a frequency band F2 as an example, the frequency spectrum resource configured for the TN includes F1 and F2, F1 is used for transmitting the NTN uplink signal and the NTN downlink signal, and the TN uplink signal, and F2 is used for transmitting the TN downlink signal. The NTN uplink signal and the NTN downlink signal are transmitted in a TDD manner, and the frequency domain resources for transmitting the NTN uplink signal and the NTN downlink signal can overlap.

[0082] Mode 1-4, the NTN uplink signal and the NTN downlink signal are transmitted on the second frequency domain resource. The NTN uplink signal and the NTN downlink signal are transmitted in a TDD manner.

[0083] In this case, the downlink transmission of the NTN and the uplink transmission of the NTN occupy the second frequency domain resource configured for the TN, and the first frequency domain resource configured for the TN is not shared with the NTN, and thus the shared frequency domain resource includes the second frequency domain resource.

[0084] The uplink transmission and the downlink transmission of the NTN both use the second frequency domain resource configured for the TN, and the first frequency domain resource configured for the TN is only used for transmitting the uplink transmission of the TN. In this way, since the first frequency domain resource of the TN is only used for transmitting the TN uplink signal without the interference of the NTN signal, this mode not only can improve the resource utilization, but also can preferentially guarantee the quality of the uplink transmission of the TN, and can be applicable to a scenario in which the uplink transmission of the TN needs to be preferentially guaranteed. For example, in some simulation or test scenarios, when the uplink transmission of the TN is seriously interfered when the TN shares the frequency spectrum with the NTN, this mode can be used.

[0085] Fig. 7 shows a schematic diagram of a manner 1-4. Exemplarily, taking a first frequency domain resource as a frequency band F1 and a second frequency domain resource as a frequency band F2 as examples, the frequency spectrum resource configured for the TN includes the F1 and the F2, the F1 is used for transmitting the TN uplink signal, the F2 is used for transmitting the NTN uplink signal and the NTN downlink signal, and the TN downlink signal. The NTN uplink signal and the NTN downlink signal are transmitted in a TDD manner, and the frequency domain resources for transmitting the NTN uplink signal and the NTN downlink signal can overlap.

[0086] Manner 1-5, transmitting the NTN uplink signal and the NTN downlink signal on the first frequency domain resource. The NTN uplink signal and the NTN downlink signal are transmitted in an FDD manner.

[0087] In this case, the NTN downlink transmission and the NTN uplink transmission occupy the first frequency domain resource configured for the TN, and the second frequency domain resource configured for the TN is not shared by the NTN, so the shared frequency domain resource includes the first frequency domain resource.

[0088] The NTN uplink transmission and the NTN downlink transmission both use the first frequency domain resource configured for the TN, and the second frequency domain resource configured for the TN is only used for the NTN downlink transmission. In this way, since the second frequency domain resource of the TN is only used for transmitting the TN downlink signal without the interference of the NTN signal, this manner not only can improve the resource utilization rate, but also can preferentially guarantee the quality of the TN downlink transmission, and is suitable for scenarios that need to preferentially guarantee the TN downlink transmission.

[0089] Fig. 8 shows a schematic diagram of a manner 1-5. Exemplarily, taking a first frequency domain resource as a frequency band F1 and a second frequency domain resource as a frequency band F2 as examples, the frequency spectrum resource configured for the TN includes the F1 and the F2, the F1 is used for transmitting the NTN uplink signal and the NTN downlink signal, and the TN uplink signal, and the F2 is used for transmitting the TN downlink signal. The NTN uplink signal and the NTN downlink signal are transmitted in an FDD manner, and the time domain resources for transmitting the NTN uplink signal and the NTN downlink signal can overlap. For example, the frequency band F1 includes a frequency band F1-1 and a frequency band F1-2, the frequency band F1-1 is used for transmitting the NTN uplink signal, and the frequency band F1-2 is used for transmitting the NTN downlink signal.

[0090] Manner 1-6, transmitting the NTN uplink signal and the NTN downlink signal on the second frequency domain resource. The NTN uplink signal and the NTN downlink signal are transmitted in an FDD manner.

[0091] In this case, the NTN downlink transmission and the NTN uplink transmission occupy the second frequency domain resource configured for the TN, and the first frequency domain resource configured for the TN is not shared by the NTN, so the shared frequency domain resource includes the second frequency domain resource.

[0092] The uplink transmission and the downlink transmission of the NTN both use the second frequency domain resource configured to the TN, and the first frequency domain resource configured to the TN is only used for transmitting the uplink transmission of the TN. In this way, since the first frequency domain resource of the TN is only used for transmitting the uplink signal of the TN without the interference of the signal of the NTN, this manner not only can improve the resource utilization rate, but also can preferentially guarantee the quality of the uplink transmission of the TN, and can be applicable to a scenario in which the uplink transmission of the TN needs to be preferentially guaranteed. For example, in some simulation or test scenarios, when the uplink transmission of the TN is seriously interfered when the TN shares the spectrum with the NTN, this manner can be used.

[0093] FIG. 9 shows a schematic diagram of a manner 1-6. Exemplarily, taking the first frequency domain resource as a frequency band F1 and the second frequency domain resource as a frequency band F2 as an example, the spectrum resource configured to the TN includes the F1 and the F2, the F1 is used for transmitting the uplink signal of the TN, the F2 is used for transmitting the uplink signal of the NTN and the downlink signal of the NTN, and the downlink signal of the TN. The uplink signal of the NTN and the downlink signal of the NTN are transmitted in the manner of FDD, and the time domain resources for transmitting the uplink signal of the NTN and the downlink signal of the NTN can overlap. For example, the frequency band F2 includes a frequency band F2-1 and a frequency band F2-2, the frequency band F2-1 is used for transmitting the uplink signal of the NTN, and the frequency band F2-2 is used for transmitting the downlink signal of the NTN.

[0094] Manner 1-7, transmitting the uplink signal or the downlink signal of the NTN on the first frequency domain resource.

[0095] In this case, the downlink transmission of the NTN or the uplink transmission of the NTN occupies the first frequency domain resource configured to the TN, and the second frequency domain resource configured to the TN is not shared with the NTN, therefore, the shared frequency domain resource includes the first frequency domain resource.

[0096] The uplink transmission or the downlink transmission of the NTN shares the first frequency domain resource configured to the TN, and the second frequency domain resource of the TN is only used for transmitting the downlink transmission of the TN. In this way, since the second frequency domain resource of the TN is only used for transmitting the downlink signal of the TN without the interference of the signal of the NTN, this manner not only can improve the resource utilization rate, but also can preferentially guarantee the quality of the downlink transmission of the TN, and can be applicable to a scenario in which the downlink transmission of the TN needs to be preferentially guaranteed.

[0097] In an implementation manner, when the uplink transmission of the NTN shares the first frequency domain resource with the uplink transmission of the TN, the NTN uplink signal can be transmitted in a manner of a supplementary uplink signal or a supplementary uplink (SUL); or when the downlink transmission of the NTN shares the first frequency domain resource with the uplink transmission of the TN, the NTN downlink signal can be transmitted in a manner of a supplementary downlink signal or a supplementary downlink (SDL).

[0098] FIG. 10 shows a schematic diagram of a manner 1-7. Exemplarily, taking a first frequency domain resource as a frequency band F1 and a second frequency domain resource as a frequency band F2 as examples, the frequency spectrum resource configured for the TN includes the F1 and the F2, the F1 is used to transmit the NTN uplink signal or the NTN downlink signal and the TN uplink signal, and the F2 is used to transmit the TN downlink signal. The NTN uplink signal is transmitted in a manner of a SUL.

[0099] Manner 1-8, transmitting the NTN uplink signal or the NTN downlink signal on the second frequency domain resource.

[0100] In this case, the downlink transmission of the NTN and the uplink transmission of the NTN occupy the second frequency domain resource configured for the TN, and the first frequency domain resource configured for the TN is not shared by the NTN, therefore, the shared frequency domain resource includes the second frequency domain resource.

[0101] The uplink transmission or the downlink transmission of the NTN adopts the second frequency domain resource configured for the TN, and the first frequency domain resource of the TN is only used to transmit the uplink transmission of the TN. In this way, since the first frequency domain resource configured for the TN is only used to transmit the TN uplink signal without the interference of the NTN signal, this manner not only can improve the resource utilization rate, but also can preferentially guarantee the quality of the uplink transmission of the TN, and can be applicable to a scenario in which the uplink transmission of the TN needs to be preferentially guaranteed.

[0102] In an implementation manner, when the uplink transmission of the NTN shares the second frequency domain resource with the downlink transmission of the TN, the NTN uplink signal can be transmitted in a manner of a SUL, and when the downlink transmission of the NTN shares the second frequency domain resource with the downlink transmission of the TN, the NTN downlink signal can be transmitted in a manner of a SDL.

[0103] FIG. 11 shows a schematic diagram of a manner 1-8. Exemplarily, taking a first frequency domain resource as a frequency band F1 and a second frequency domain resource as a frequency band F2 as examples, the frequency spectrum resource configured for the TN includes the F1 and the F2, the F2 is used to transmit the NTN uplink signal or the NTN downlink signal and the TN downlink signal, and the F1 is used to transmit the TN uplink signal. The NTN uplink signal is transmitted in a manner of a SUL.

[0104] It should be noted that in the mode 1-3 to the mode 1-8, the TN shares the transmission resource with the NTN in only one direction. For example, in the mode 1-3, the mode 1-5 and the mode 1-7, only the first frequency domain resource is shared. In the mode 1-4, the mode 1-6 and the mode 1-8, only the second frequency domain resource is shared.

[0105] The mode 1-9 transmits the NTN uplink signal and / or the NTN downlink signal on the first frequency domain resource, and transmits the NTN uplink signal and / or the NTN downlink signal on the second frequency domain resource. For example, the NTN uplink signal is transmitted on the first frequency domain resource and the second frequency domain resource, or the NTN downlink signal is transmitted on the first frequency domain resource and the second frequency domain resource.

[0106] In this case, the NTN shares the transmission resource of the TN in only one link. In addition, in the mode 1-3 to the mode 1-8, the TN shares the transmission resource with the NTN in only one transmission direction (or transmission link).

[0107] The above is nine modes of transmitting signals by the TN in the FDD mode. In the case of transmitting signals by the TN in the TDD mode, the shared frequency domain resource can be the transmission resource configured to the TN, that is, the uplink transmission and the downlink transmission of the TN are transmitted by using the same frequency domain resource. The shared frequency domain resource satisfies any one of the mode 1-10 to the mode 1-12, and the following is the description of the mode 1-10 to the mode 1-12:

[0108] The mode 1-10 transmits the NTN uplink signal and the NTN downlink signal on the shared frequency domain resource. The NTN uplink signal and the NTN downlink signal are transmitted in the TDD mode.

[0109] In this case, the downlink transmission of the NTN and the uplink transmission of the NTN share the transmission resource configured to the TN with the transmission of the TN. The transmission of the TN includes the uplink transmission and the downlink transmission of the TN.

[0110] When the shared frequency domain resource is a TDD resource, the shared frequency domain resource can be a TDD spectrum resource, for example, the spectrum resource of the uplink transmission and the downlink transmission of the TN is the same, and different time domain resources are used for transmission.

[0111] FIG. 12 shows a schematic diagram of the mode 1-10. Exemplarily, taking the shared frequency domain resource as a TDD resource as an example, the shared frequency domain resource can be used to transmit the NTN uplink signal, the NTN downlink signal, the TN uplink signal and the TN downlink signal.

[0112] The mode 1-11 transmits the NTN uplink signal and the NTN downlink signal on the shared frequency domain resource. The NTN uplink signal and the NTN downlink signal are transmitted in the FDD mode.

[0113] In this case, the downlink transmission of the NTN and the uplink transmission of the NTN share the transmission resource configured to the TN with the transmission of the TN. The transmission of the TN includes the uplink transmission and the downlink transmission of the TN.

[0114] When the shared frequency domain resource is a TDD resource, the shared frequency domain resource can be a TDD spectrum resource, for example, the spectrum resources of the uplink transmission and the downlink transmission of the TN are the same, and different time domain resources are used for transmission.

[0115] FIG. 13 shows a schematic diagram of mode 1-11. Exemplarily, taking the shared frequency domain resource as an FDD resource as an example, the shared frequency domain resource can be used to transmit the NTN uplink signal, the NTN downlink signal, the TN uplink signal, and the TN downlink signal.

[0116] Mode 1-12, transmitting the NTN uplink signal or the NTN downlink signal on the shared frequency domain resource. The NTN uplink signal is transmitted in the SUL mode; or, the NTN downlink signal is transmitted in the SDL mode.

[0117] In this case, the downlink transmission of the NTN or the uplink transmission of the NTN shares the transmission resource configured to the TN with the transmission of the TN. The transmission of the TN includes the uplink transmission and the downlink transmission of the TN.

[0118] When the shared frequency domain resource is a TDD resource, the shared frequency domain resource can be a TDD spectrum resource, for example, the spectrum resources of the uplink transmission and the downlink transmission of the TN are the same, and different time domain resources are used for transmission.

[0119] FIG. 14 shows a schematic diagram of mode 1-12. Exemplarily, taking the shared frequency domain resource as an FDD resource as an example, the shared frequency domain resource can be used to transmit the NTN uplink signal, the NTN downlink signal, the TN uplink signal, and the TN downlink signal.

[0120] It should be noted that in modes 1-10 to 1-12, due to the long delay of the NTN, a large guard period (GP) is required. Therefore, the spectrum efficiency of TDD is poor for the NTN, and most of the NTNs communicate in the FDD mode, but a small number of low earth orbit satellites (LEO) and high altitude pseudo satellites (HAPS) can communicate in the TDD mode.

[0121] Scenario two, the target frequency domain resource includes the resource configured to the NTN

[0122] The resource configured to the NTN includes a transmission resource configured (or allocated) to the NTN, i.e., a transmission resource used for transmitting an NTN signal. The shared frequency domain resource can include a frequency domain resource configured to the NTN, and the TN shares the transmission resource of the NTN in a supplementary manner. In this way, the nodes in the TN can also transmit signals on the resource configured to the NTN, thereby improving resource utilization.

[0123] In some embodiments, the frequency domain resource configured to the NTN includes a third frequency domain resource and / or a fourth frequency domain resource. The third frequency domain resource is used for transmitting an NTN uplink signal, i.e., the third frequency domain resource is an uplink transmission resource (e.g., frequency band F1) used for transmitting an uplink NTN signal; the fourth frequency domain resource is used for transmitting an NTN downlink signal, i.e., the fourth frequency domain resource is a downlink transmission resource (e.g., frequency band F2) used for transmitting a downlink NTN signal. For example, the NTN transmits an uplink NTN signal on the frequency band F1 and transmits a downlink NTN signal on the frequency band F2. It should be understood that in this case, the NTN signals are transmitted in an FDD manner.

[0124] It should be noted that in different sharing manners, the shared frequency domain resource includes different resources, or the shared frequency domain resource is used for transmitting signals of different types. The shared frequency domain resource can satisfy any one of modes 2-1 to 2-9, which will be described below.

[0125] Mode 2-1: transmitting a TN uplink signal on the third frequency domain resource and transmitting a TN downlink signal on the fourth frequency domain resource. In this case, the shared frequency domain resource includes the third frequency domain resource and the fourth frequency domain resource.

[0126] The uplink transmission of the TN occupies the uplink transmission resource configured to the NTN, i.e., the third frequency domain resource; and the downlink transmission of the TN occupies the downlink transmission resource configured to the NTN, i.e., the fourth frequency domain resource. In this way, the signal transmission of the TN can occupy the transmission resource configured to the NTN, and the directions of the signals transmitted by the shared frequency domain resource are the same (i.e., the TN uplink signal and the NTN uplink signal are transmitted on the third frequency domain resource, or the TN downlink signal and the NTN downlink signal are transmitted on the fourth frequency domain resource), thereby reducing the cross-link interference. In addition, both the uplink and downlink resources configured to the NTN can be shared to the TN, thereby further improving the spectrum utilization.

[0127] FIG. 15 shows a schematic diagram of mode 2-1. 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 resource includes F1 and F2, F1 is used for transmitting a TN uplink signal and an NTN uplink signal, and F2 is used for transmitting a TN downlink signal and an NTN downlink signal.

[0128] Mode 2-2, transmitting TN downlink signals on the third frequency domain resource and transmitting TN uplink signals on the fourth frequency domain resource. In this case, the shared frequency domain resource includes the third frequency domain resource and the fourth frequency domain resource.

[0129] The downlink transmission of the TN occupies the uplink transmission resource configured to the NTN, i.e., the third frequency domain resource; the uplink transmission of the TN occupies the downlink transmission resource configured to the NTN, i.e., the fourth frequency domain resource. In this way, the transmission of the TN occupies the transmission resource configured to the NTN, and the shared frequency domain resource is used for signals in opposite directions (i.e., TN downlink signals and NTN uplink signals are transmitted on the third frequency domain resource, or TN uplink signals and NTN downlink signals are transmitted on the fourth frequency domain resource), so that the interference from the signals in the same direction can be reduced. In addition, the uplink and downlink resources of the NTN can be shared to the TN, thereby further improving the spectrum utilization.

[0130] FIG. 16 shows a schematic diagram of mode 2-2. 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 resource includes 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.

[0131] Mode 2-3, transmitting TN uplink signals and TN downlink signals on the third frequency domain resource. The TN uplink signals and the TN downlink signals are transmitted in a TDD manner.

[0132] In this case, the downlink transmission of the TN and the uplink transmission of the TN occupy the third frequency domain resource configured to the NTN, and the fourth frequency domain resource configured to the NTN is not shared to the TN, so the shared frequency domain resource includes the third frequency domain resource.

[0133] The uplink transmission and the downlink transmission of the TN both use the third frequency domain resource configured to the NTN, and the fourth frequency domain resource configured to the NTN is only used for the downlink transmission of the NTN. In this way, since the fourth frequency domain resource of the NTN is only used for transmitting the NTN downlink signals without the interference of the TN signals, this mode not only can improve the resource utilization, but also can preferentially guarantee the quality of the downlink transmission of the NTN, and is suitable for scenarios where the downlink transmission of the NTN needs to be preferentially guaranteed.

[0134] FIG. 17 shows a schematic diagram of mode 2-3. 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 frequency spectrum resource configured to the NTN includes F1 and F2, F1 is used to transmit TN uplink signals and TN downlink signals, and NTN uplink signals, and F2 is used to transmit NTN downlink signals. The TN uplink signals and the TN downlink signals are transmitted in a TDD manner, and the frequency domain resources for transmitting the TN uplink signals and the TN downlink signals can overlap.

[0135] Mode 2-4, TN uplink signals and TN downlink signals are transmitted on the fourth frequency domain resource. The TN uplink signals and the TN downlink signals are transmitted in a TDD manner.

[0136] In this case, the downlink transmission of the TN and the uplink transmission of the TN occupy the fourth frequency domain resource configured for the NTN, and the third frequency domain resource configured for the NTN is not shared by the TN, so the shared frequency domain resource includes the fourth frequency domain resource.

[0137] The uplink transmission and the downlink transmission of the TN both use the fourth frequency domain resource configured for the NTN, and the third frequency domain resource configured for the NTN is only used for transmitting the uplink transmission of the NTN. In this way, since the third frequency domain resource of the NTN is only used for transmitting the NTN uplink signals without interference from the TN signals, this mode not only can improve the resource utilization, but also can preferentially guarantee the quality of the uplink transmission of the NTN, and can be applied to a scenario in which the uplink transmission of the NTN needs to be preferentially guaranteed. For example, in some simulation or test scenarios, when the NTN shares the spectrum with the TN, and the uplink transmission of the NTN is seriously interfered, this mode can be used.

[0138] FIG. 18 shows a schematic diagram of a mode 2-4. Exemplarily, taking the third frequency domain resource as a frequency band F1 and the fourth frequency domain resource as a frequency band F2 as an example, the frequency spectrum resource of the NTN includes F1 and F2, F1 is used for transmitting the NTN uplink signals, F2 is used for transmitting the TN uplink signals and the TN downlink signals, and the NTN downlink signals. The TN uplink signals and the TN downlink signals are transmitted in a TDD manner, and the frequency domain resources for transmitting the TN uplink signals and the TN downlink signals can overlap.

[0139] Mode 2-5, TN uplink signals and TN downlink signals are transmitted on the third frequency domain resource. The TN uplink signals and the TN downlink signals are transmitted in an FDD manner.

[0140] In this case, the downlink transmission of the TN and the uplink transmission of the TN occupy the third frequency domain resource configured for the NTN, and the fourth frequency domain resource configured for the NTN is not shared by the TN, so the shared frequency domain resource includes the third frequency domain resource.

[0141] The uplink transmission and the downlink transmission of the TN both use the third frequency domain resource configured for the NTN, and the fourth frequency domain resource configured for the NTN is only used for the downlink transmission of the NTN. In this way, since the fourth frequency domain resource of the NTN is only used for transmitting the NTN downlink signals without interference from the TN signals, this mode not only can improve the resource utilization, but also can preferentially guarantee the quality of the downlink transmission of the NTN, and can be applied to a scenario in which the downlink transmission of the NTN needs to be preferentially guaranteed.

[0142] FIG. 19 shows a schematic diagram of a manner 2-5. Exemplarily, taking a third frequency domain resource as a frequency band F1 and a fourth frequency domain resource as a frequency band F2 as examples, the frequency spectrum resource configured to the NTN includes the F1 and the F2, the F1 is used to transmit TN uplink signals and TN downlink signals, and NTN uplink signals, and the F2 is used to transmit NTN downlink signals. The TN uplink signals and the TN downlink signals are transmitted in an FDD manner, and the time domain resources for transmitting the TN uplink signals and the TN downlink signals can overlap. For example, the frequency band F1 includes a frequency band F1-1 and a frequency band F1-2, the frequency band F1-1 is used to transmit TN uplink signals, and the frequency band F1-2 is used to transmit TN downlink signals.

[0143] Manner 2-6, transmitting TN uplink signals and TN downlink signals on the fourth frequency domain resource. The TN uplink signals and the TN downlink signals are transmitted in an FDD manner.

[0144] In this case, the downlink transmission of the TN and the uplink transmission of the TN occupy the fourth frequency domain resource configured to the NTN, and the third frequency domain resource configured to the NTN is not shared by the TN, therefore, the shared frequency domain resource includes the fourth frequency domain resource.

[0145] The uplink transmission and the downlink transmission of the TN both use the fourth frequency domain resource configured to the NTN, and the third frequency domain resource configured to the NTN is only used to transmit the uplink transmission of the NTN. In this way, since the third frequency domain resource of the NTN is only used to transmit the TN uplink signals without the interference of the TN signals, this manner not only can improve the resource utilization rate, but also can preferentially guarantee the quality of the uplink transmission of the NTN, and can be applicable to scenarios in which the uplink transmission of the NTN needs to be preferentially guaranteed. For example, in some simulation or test scenarios, when the uplink transmission of the NTN is seriously interfered when the NTN shares the frequency spectrum with the TN, this manner can be used.

[0146] FIG. 20 shows a schematic diagram of a manner 2-6. Exemplarily, taking a third frequency domain resource as a frequency band F1 and a fourth frequency domain resource as a frequency band F2 as examples, the frequency spectrum resource configured to the NTN includes the F1 and the F2, the F1 is used to transmit TN uplink signals, and the F2 is used to transmit TN uplink signals and TN downlink signals, and NTN downlink signals. The TN uplink signals and the TN downlink signals are transmitted in an FDD manner, and the time domain resources for transmitting the TN uplink signals and the TN downlink signals can overlap. For example, the frequency band F2 includes a frequency band F2-1 and a frequency band F2-2, the frequency band F2-1 is used to transmit TN uplink signals, and the frequency band F2-2 is used to transmit TN downlink signals.

[0147] Manner 2-7, transmitting TN uplink signals or TN downlink signals on the third frequency domain resource.

[0148] In this case, the downlink transmission of the TN or the uplink transmission of the TN occupies the third frequency domain resource configured for the NTN, and the fourth frequency domain resource configured for the NTN is not shared with the TN, and thus the shared frequency domain resource includes the third frequency domain resource.

[0149] The uplink transmission or the downlink transmission of the TN shares the third frequency domain resource configured for the NTN, and the fourth frequency domain resource of the NTN is only used for transmitting the downlink transmission of the NTN. In this way, since the fourth frequency domain resource of the NTN is only used for transmitting the downlink signal of the NTN without the signal of the TN for interference, this mode not only can improve the resource utilization, but also can preferentially guarantee the quality of the downlink transmission of the NTN, and can be applicable to a scenario in which the downlink transmission of the NTN needs to be preferentially guaranteed.

[0150] In an implementation manner, when the uplink transmission of the TN shares the third frequency domain resource with the uplink transmission of the NTN, the SUL mode can be used for transmission; or when the downlink transmission of the TN shares the third frequency domain resource with the uplink transmission of the NTN, the SDL mode can be used for transmission.

[0151] FIG. 21 shows a schematic diagram of a mode 2-7. Exemplarily, taking the third frequency domain resource as a frequency band F1 and the fourth frequency domain resource as a frequency band F2 as an example, the frequency spectrum resource configured for the NTN includes F1 and F2, F1 is used for transmitting the uplink signal of the TN or the downlink signal of the TN and the uplink signal of the NTN, and F2 is used for transmitting the downlink signal of the NTN. The uplink signal of the TN is transmitted in the SUL mode.

[0152] Mode 2-8, transmitting the uplink signal of the TN or the downlink signal of the TN on the fourth frequency domain resource.

[0153] In this case, the downlink transmission of the TN and the uplink transmission of the TN occupy the fourth frequency domain resource configured for the NTN, and the third frequency domain resource configured for the NTN is not shared with the TN, and thus the shared frequency domain resource includes the fourth frequency domain resource.

[0154] The uplink transmission or the downlink transmission of the TN uses the fourth frequency domain resource configured for the NTN, and the third frequency domain resource of the NTN is only used for transmitting the uplink transmission of the NTN. In this way, since the third frequency domain resource configured for the NTN is only used for transmitting the uplink signal of the NTN without the signal of the TN for interference, this mode not only can improve the resource utilization, but also can preferentially guarantee the quality of the uplink transmission of the NTN, and can be applicable to a scenario in which the uplink transmission of the NTN needs to be preferentially guaranteed.

[0155] In an implementation manner, when the uplink transmission of the TN shares the fourth frequency domain resource with the downlink transmission of the NTN, the SUL mode can be used for transmission, and when the downlink transmission of the TN shares the fourth frequency domain resource with the downlink transmission of the NTN, the SDL mode can be used for transmission.

[0156] FIG. 22 shows a schematic diagram of a manner 2-8. Exemplarily, the fourth frequency domain resource is frequency band F1, and the fourth frequency domain resource is frequency band F2. The frequency spectrum resource configured to the NTN includes F1 and F2. F2 is used to transmit TN uplink signals or TN downlink signals, and NTN downlink signals. F1 is used to transmit NTN uplink signals. The TN uplink signals are transmitted in the manner of SUL.

[0157] It should be noted that in manners 2-3 to 2-8, the NTN only shares one transmission direction with the TN. For example, in manners 2-3, 2-5, and 2-7, only the third frequency domain resource is shared. In manners 2-4, 2-6, and 2-8, only the fourth frequency domain resource is shared.

[0158] Manner 2-9, TN uplink signals and / or TN downlink signals are transmitted on the third frequency domain resource, and TN uplink signals and / or TN downlink signals are transmitted on the fourth frequency domain resource. For example, TN uplink signals are transmitted on the third frequency domain resource and the fourth frequency domain resource, or TN downlink signals are transmitted on the third frequency domain resource and the fourth frequency domain resource.

[0159] In this case, the TN only shares one link with the transmission resource configured to the NTN. In addition, in manners 2-3 to 2-8, the NTN only shares one transmission direction (or transmission link) with the TN.

[0160] The above are nine manners of transmitting signals by the NTN in the FDD manner. In the case of transmitting signals by the NTN in the TDD manner, the shared frequency domain resource can be the transmission resource configured to the NTN, that is, the uplink transmission and the downlink transmission of the NTN are transmitted by using the same frequency domain resource. The shared frequency domain resource satisfies any one of manners 2-10 to 2-12, and the following is a description of manners 2-10 to 2-12:

[0161] Manner 2-10, TN uplink signals and TN downlink signals are transmitted on the shared frequency domain resource. The TN uplink signals and the TN downlink signals are transmitted in the TDD manner.

[0162] In this case, the downlink transmission of the TN and the uplink transmission of the TN share the transmission resource configured to the NTN with the transmission of the NTN. The transmission of the NTN includes the uplink transmission and the downlink transmission of the NTN.

[0163] When the shared frequency domain resource is a TDD resource, the shared frequency domain resource can be a TDD frequency spectrum resource, for example, the frequency spectrum resource of the uplink transmission and the downlink transmission of the NTN is the same, and different time domain resources are used for transmission.

[0164] FIG. 23 shows a schematic diagram of a manner 2-10. Exemplarily, taking a shared frequency domain resource as a TDD resource as an example, the TN uplink signal, the TN downlink signal, the NTN uplink signal, and the NTN downlink signal can be transmitted by using the shared frequency domain resource.

[0165] Manner 2-11, transmitting the TN uplink signal and the TN downlink signal on the shared frequency domain resource. The TN uplink signal and the TN downlink signal are transmitted in an FDD manner.

[0166] In this case, the downlink transmission of the TN and the uplink transmission of the TN share the transmission resource configured for the NTN with the transmission of the NTN. The transmission of the NTN includes the uplink transmission and the downlink transmission of the NTN.

[0167] When the shared frequency domain resource is a TDD resource, the shared frequency domain resource can be a TDD spectrum resource, for example, the spectrum resource of the uplink transmission and the downlink transmission of the NTN is the same, and the uplink transmission and the downlink transmission of the NTN are transmitted by using different time domain resources.

[0168] FIG. 24 shows a schematic diagram of a manner 2-11. Exemplarily, taking a shared frequency domain resource as a FDD resource as an example, the TN uplink signal, the TN downlink signal, the NTN uplink signal, and the NTN downlink signal can be transmitted by using the shared frequency domain resource.

[0169] Manner 2-12, transmitting the TN uplink signal or the TN downlink signal on the shared frequency domain resource. The TN uplink signal is transmitted in an SUL manner; or, the TN downlink signal is transmitted in an SDL manner.

[0170] In this case, the downlink transmission of the TN or the uplink transmission of the TN shares the transmission resource configured for the NTN with the transmission of the NTN. The transmission of the NTN includes the uplink transmission and the downlink transmission of the NTN.

[0171] When the shared frequency domain resource is a TDD resource, the shared frequency domain resource can be a TDD spectrum resource, for example, the spectrum resource of the uplink transmission and the downlink transmission of the NTN is the same, and the uplink transmission and the downlink transmission of the NTN are transmitted by using different time domain resources.

[0172] FIG. 25 shows a schematic diagram of a manner 2-12. Exemplarily, taking a shared frequency domain resource as a FDD resource as an example, the TN uplink signal, the TN downlink signal, the NTN uplink signal, and the NTN downlink signal can be transmitted by using the shared frequency domain resource.

[0173] Scenario three, the target frequency domain resource includes the frequency domain resource configured for the NTN and the TN

[0174] The frequency domain resource configured to the NTN and the TN can be any frequency domain resource, instead of a transmission resource configured to the NTN or the TN, and the NTN and the TN can jointly use the shared frequency domain resource in a fair or agreed (based on rules or coordination) manner. In this way, both the TN and the NTN can transmit signals through the shared frequency domain resource, without allocating transmission resources for the NTN and the TN, thereby saving transmission resources and improving resource utilization.

[0175] It should be noted that in different sharing manners, the shared frequency domain resource includes different resources or is used for transmission of different types of signals. The shared frequency domain resource can satisfy any one of modes 3-1 to 3-10, and ten manners in which the TN and the NTN share the shared frequency domain resource will be described below (it should be understood that the difference between scenario three and scenario one and scenario two is that the shared frequency domain resource is a resource configured to whom, and the correspondence between the manners in scenario three and the manners in scenario one and scenario two will be given below) :

[0176] Mode 3-1, the shared frequency domain resource is used for transmission of TN uplink signals and / or TN downlink signals and NTN uplink signals. The downlink transmission of the NTN does not share resources with the transmission of the TN.

[0177] For example, the TN uplink signals and the TN downlink signals can be transmitted on the shared frequency domain resource in a TDD manner, corresponding to mode 2-3.

[0178] Alternatively, the TN uplink signals and the TN downlink signals can be transmitted on the shared frequency domain resource in an FDD manner, corresponding to mode 2-5.

[0179] Alternatively, the TN uplink signals or the TN downlink signals and the NTN uplink signals are transmitted on the shared frequency domain resource, and the TN uplink signals can be transmitted in an SUL manner, and the TN downlink signals can be transmitted in an SDL manner, corresponding to mode 2-7.

[0180] Mode 3-2, the shared frequency domain resource is used for transmission of TN uplink signals and / or TN downlink signals and NTN downlink signals. The uplink transmission of the NTN does not share resources with the transmission of the TN.

[0181] For example, the TN uplink signals and the TN downlink signals can be transmitted on the shared frequency domain resource in a TDD manner, corresponding to mode 2-4.

[0182] Alternatively, the TN uplink signals and the TN downlink signals can be transmitted on the shared frequency domain resource in an FDD manner, corresponding to mode 2-6.

[0183] Alternatively, the TN uplink signal or the TN downlink signal, and the NTN downlink signal are transmitted on the shared frequency domain resource, and the TN uplink signal can be transmitted in the manner of SUL, and the TN downlink signal can be transmitted in the manner of SDL, corresponding to mode 2-8.

[0184] Mode 3-3, the shared frequency domain resource is used to transmit the TN uplink signal or the TN downlink signal, and the NTN uplink signal and the NTN downlink signal.

[0185] For example, the TN uplink signal or the TN downlink signal, and the signal (including the uplink signal and the downlink signal) of the NTN are transmitted on the shared frequency domain resource, corresponding to mode 2-9.

[0186] Mode 3-4, the shared frequency domain resource is used to transmit the NTN uplink signal and / or the NTN downlink signal, and the TN uplink signal. The downlink transmission of the TN does not share the resource with the NTN transmission.

[0187] For example, the NTN uplink signal and the NTN downlink signal can be transmitted on the shared frequency domain resource in the manner of TDD, corresponding to mode 1-3.

[0188] Alternatively, the NTN uplink signal and the NTN downlink signal can be transmitted on the shared frequency domain resource in the manner of FDD, corresponding to mode 1-5.

[0189] Alternatively, the NTN uplink signal or the NTN downlink signal and the TN uplink signal are transmitted on the shared frequency domain resource, and the NTN uplink signal can be transmitted in the manner of SUL, and the NTN downlink signal can be transmitted in the manner of SDL, corresponding to mode 1-7.

[0190] Mode 3-5, the shared frequency domain resource is used to transmit the NTN uplink signal and / or the NTN downlink signal, and the TN downlink signal. The uplink transmission of the TN does not share the resource with the NTN transmission.

[0191] For example, the NTN uplink signal and the NTN downlink signal can be transmitted on the shared frequency domain resource in the manner of TDD, corresponding to mode 1-4.

[0206] Alternatively, TN uplink signals can be transmitted in an SUL manner, and TN downlink signals can be transmitted in an SDL manner, corresponding to way 2-12.

[0207] In addition, before the first node transmits NTN signals and TN signals through the shared frequency domain resource, the configuration information of the shared frequency domain resource needs to be indicated to the NTN or the TN or the NTN or the TN needs to be instructed to switch the sharing manner, and the configuration information can include at least one of the following: a scenario of the shared frequency domain resource; a sharing manner; parameters of the shared frequency domain resource.

[0208] The scenario of the shared frequency domain resource is a scenario in which the shared manner is used to transmit signals. The sharing manner is the type of the shared frequency domain resource (for example, the first frequency domain resource or the third frequency domain resource) or the type of signals transmitted by the shared frequency domain resource. The parameters of the shared frequency domain resource include at least one of the following: configuration information of a specific signal (for example, a physical uplink control channel (PUCCH), a sounding reference signal (SRS)) on the shared frequency domain resource; initial bandwidth part (BWP) configuration information; BWP serial number; RB set serial number; sub-band serial number; condition for using the shared frequency domain resource; starting time of sharing; effective duration of sharing; whether the shared frequency domain resource is a TDD resource or an FDD resource.

[0209] The following will describe multiple ways of indicating the configuration information of the shared frequency domain resource to the TN or the NTN through way 4-1 to way 4-7 respectively:

[0210] Mode 4-1, the shared frequency domain resource is configured to the base station or terminal of TN or NTN by the network or system (e.g., spectrum access system, spectrum management system, etc.). 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, i.e., determining which resources are included in the shared frequency domain resource or determining which types of signals (e.g., NTN uplink signal and TN uplink signal) are used for transmission by the shared frequency domain resource, or dynamically allocating spectrum resources, or performing interference coordination. The system can be an independent node or entity, or can be integrated into the TN base station or NTN base station (i.e., satellite).

[0211] Mode 4-2, the configuration information of the shared frequency domain resource is indicated to the TN base station or NTN base station by the core network / operation administration and maintenance (OAM).

[0212] Mode 4-3, the configuration information of the shared frequency domain resource is determined between the NTN (e.g., NTN base station) and TN (e.g., TN base station) by them. 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 of determining the shared frequency domain resource, the sharing mode, and / or the parameters of the shared frequency domain resource, etc. Then, the NTN base station can feed back a confirmation message to the TN base station. The above steps are not indispensable, but can be performed alone or in combination. In an implementation mode, the sharing request message can be initiated by the network that wants to share the spectrum and sent to the network that is shared by the spectrum, for example, in the case of NTN sharing the frequency domain resource configured to TN, the NTN base station can send a sharing request message to the TN base station.

[0213] Mode 4-4, the shared frequency domain resource is configured or indicated to the terminal by the base station or network (e.g., TN base station or NTN base station) through system information (e.g., synchronization signal block (SSB), master information block (MIB), system information block (SIB) (SIB1, SIB19 or other system information block), radio resource control signaling (RRC) signaling, medium access control control element (MAC CE), downlink control information (DCI) signaling, etc.).

[0214] Manner 4-5, the configuration information of the shared frequency domain resource is determined by the first network (e.g., base station) and indicated to the second network (e.g., base station). The first network is the network of the shared resource, and the second network is the network of the shared resource. For example, in the case that the shared frequency domain resource includes the spectrum resource configured to the NTN, the NTN is the network of the shared resource, and the TN is the network of the shared resource.

[0215] Manner 4-6, the first node receives a switching indication message and switches the type of the shared frequency domain resource or the type of the signal used for transmission of the shared frequency domain resource based on the switching indication message. For example, the NTN base station / satellite can send a switching indication message to the TN base station, so as to instruct the TN base station to switch the sharing manner; or the TN base station can send a switching indication message to the NTN base station / satellite, so as to instruct the NTN base station / satellite to switch the sharing manner; or the terminal can send a switching indication message to the NTN base station, satellite or TN base station, so as to instruct the NTN satellite or TN base station to switch the sharing manner; or the NTN base station / satellite or TN base station sends a switching indication message to the terminal, so as to make the terminal switch the sharing manner. In an implementation manner, the switching indication message can include the measurement result.

[0216] In an implementation manner, the NTN base station / satellite can receive the measurement result 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 result, it can be determined that the signal quality is poor. Therefore, in the case that the NTN base station / satellite supports multiple sharing manners, the NTN base station / satellite can determine that the sharing manner needs to be switched (for example, from manner 1-1 to manner 1-2), that is, the type of the shared frequency domain resource or the type of the signal used for transmission of the shared frequency domain resource is switched, for example, the first frequency domain resource in manner 1-3 is switched to the second frequency domain resource in manner 1-4, or the first frequency domain resource in manner 1-3 is used for transmission of the NTN uplink signal and the NTN downlink signal, and is switched to the first frequency domain resource in manner 1-7 for transmission of the NTN uplink signal or the NTN downlink signal. In addition, after the NTN base station / satellite switches the sharing manner, the NTN terminal can also be sent with second information to instruct the NTN terminal to switch the sharing manner to the sharing manner switched by the NTN base station.

[0217] It should be noted that the NTN base station / satellite can determine the switching of the sharing manner based on the switching indication message reported by the NTN terminal, or determine the switching of the sharing manner based on the switching indication message from the TN base station. For example, in the case that the shared frequency domain resource is the transmission resource configured to the NTN, the NTN base station / satellite can send a switching indication message to the TN base station, so as to instruct or request the TN base station to switch the sharing manner, or apply for the information of the switching of the sharing manner to the TN base station.

[0218] In yet another implementation, the NTN and the TN can adopt a resource sharing mode (e.g., mode 3-1) by default. In the case that the interference parameter of the signal is greater than a preset parameter value (or the signal quality parameter is less than a preset parameter value), the NTN and the TN switch the resource sharing mode (e.g., mode 3-2), thereby reducing the interference. If the NTN and the TN support two sharing modes, a bit can be used to determine whether to switch, for example, bit 0 is used to represent the first sharing mode, and bit 1 is used to represent the second sharing mode. In the case that the NTN and the TN support more than two sharing modes, a bit map, an index, enumeration, or the like can be used to indicate the switching of the sharing mode.

[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 change of the measurement result or topology (e.g., measurement, ephemeris, or the like). The switching request message can be carried by PUCCH, physical uplink shared channel (PUSCH), an uplink reference signal, or a sequence of a signal / channel. The base station or satellite can feed back a switching request confirmation message to the terminal based on the request message. The switching request confirmation message can include any one of the following: allow switching; do not allow switching; 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.
