[0041] Before introducing the technical solutions of this application, we first introduce and explain some of the relevant technical knowledge involved in this application. The following related technologies can be combined with the technical solutions of the embodiments of this application as optional solutions, and they all fall within the scope of protection of the embodiments of this application. The embodiments of this application include at least part of the following contents.

[0042] 1. Network scenario

[0043] Communication system scenarios include TN and NTN. NTN generally uses satellite communications to provide communication services to terrestrial users. Currently, NTN systems include NR-NTN and IoT-NTN, and other NTN systems may be added in the future.

[0044] For example, Figure 2A is a schematic diagram of the architecture of a communication system provided in an embodiment of the present application. As shown in Figure 2A, the communication system may include a network device 210, which may be a device that communicates with a terminal device 220 (or referred to as a communication terminal device or terminal device). Network device 210 can provide communication coverage for a specific geographic area and can communicate with terminal devices located within the coverage area.

[0045] Figure 2A exemplarily shows a network device and two terminal devices. In some embodiments of the present application, the communication system may include multiple network devices and the coverage area of ​​each network device may include other numbers of terminal devices, which is not limited in the embodiments of the present application.

[0046] 2B is a schematic diagram of the architecture of another communication system provided in an embodiment of the present application. Referring to FIG2B , a terminal device 2101 and a satellite 2102 are included, and wireless communication can be performed between the terminal device 2101 and the satellite 2102. The network formed between the terminal device 2101 and the satellite 2102 can also be referred to as an NTN. In the architecture of the communication system shown in FIG2B , the satellite 2102 can have the function of a base station, and the terminal device 2101 and the satellite 2102 can communicate directly. In the system architecture, the satellite 2102 can be referred to as a network device. In some embodiments of the present application, a plurality of network devices 2102 may be included in the communication system, and each network device 2102 may include other number of terminal devices within its coverage area, which is not limited in the embodiments of the present application.

[0047] In future evolved communication systems such as B5G or 6G, distributed multiple-input multiple-output (Distributed MIMO, also known as distributed antenna systems) scenarios and / or massive multiple-input multiple-output (Massive MIMO, also known as massive antenna matrix systems) scenarios may also be included. In some cases, Distributed MIMO and / or Massive MIMO may also support cell-free or terminal-centric (UE-centric) networking scenarios. It should be understood that the above scenarios are also applicable to TN and / or NTN. It is understandable that due to the scarcity of spectrum resources, whether it is a base station-centric networking scenario or a terminal-centric networking scenario, it may be necessary for TN and NTN to share spectrum.

[0048] 2C is a schematic diagram of the architecture of another communication system provided in an embodiment of the present application. Referring to FIG2C , it includes a terminal device 2201, a satellite 2202, and a base station 2203. Wireless communication can be performed between the terminal device 2201 and the satellite 2202, and communication can be performed between the satellite 2202 and the base station 2203. The network formed between the terminal device 2201, the satellite 2202, and the base station 2203 can also be referred to as an NTN. In the architecture of the communication system shown in FIG2C , the satellite 2202 may not have the function of a base station, and the communication between the terminal device 2201 and the base station 2203 needs to be transferred through the satellite 2202. In this system architecture, the base station 2203 can be referred to as a network device. In some embodiments of the present application, a plurality of network devices 2203 may be included in the communication system, and each network device 2203 may include other number of terminal devices within its coverage area, which is not limited in the embodiments of the present application.

[0049] 2. Beam direction limitation in NR system

[0050] In an NR system, the initial access process of a terminal device is accomplished by detecting the synchronization signal block (SSB or SS / PBCH block) on the synchronization raster. SSB is transmitted through the discovery signal transmission opportunity window (DBT) or SSB transmission opportunity window (SSB). The discovery signal transmission opportunity window or SSB transmission opportunity window occurs periodically, and the period can be configured by the network device through high-layer parameters.

[0051] One of the main functions of the SSB index is to allow the UE to obtain system timing information. In addition, the SSB index has another function, which is to indicate the Quasi Co-Location (QCL) relationship between SSBs. Alternatively, the SSB index can be understood as indicating the beam direction. QCL means that the large-scale parameters of the channel experienced by the symbols on one antenna port can be inferred from the channel experienced by the symbols on another antenna port. These large-scale parameters can include delay spread, average delay, Doppler spread, Doppler shift, and spatial reception parameters. Specifically for SSBs, in the 5G NR system, SSBs carried by different beams constitute an SSB burst set. Different SSB indices correspond to different SSB time domain position information within the burst set, as well as specific SSB transmission beam information. SSBs with the same SSB index can be considered to have a QCL relationship; in other words, SSBs with the same SSB index experience the same or similar large-scale channel parameters. The UE may assume that the network device uses the same beam to transmit these SSBs; there is no QCL relationship between SSBs corresponding to different SSB indices, because they may come from different transmission beams of the network device and experience different channel transmission characteristics.

[0052] After the terminal device accesses the cell, if there is a demand for service transmission, it needs to access the network through the random access process. The resource configuration in the random access process includes PRACH (Physical Random Access Channel) resource configuration, also known as PRACH transmission opportunity (PRACH Occasion, RO). RO is the time-frequency resource that carries the random access preamble sequence (Preamble). If two-step RACH transmission is supported, the resource configuration in the random access process also includes PUSCH (Physical Uplink Shared Channel) resource configuration, also known as PUSCH transmission opportunity (PUSCH Occasion, PO). Among them, the message A (Msg A) in the two-step RACH includes Msg A Preamble and Msg A PUSCH, RO is the time-frequency resource used to carry Msg A Preamble, and PO is the time-frequency resource used to carry Msg A PUSCH.

[0053] The NR system is characterized by its support for downlink multi-beams. Before a network device communicates with a terminal device, it needs to know the beam the terminal device is in and then set the appropriate beam direction during subsequent data transmission. Due to the mapping relationship between SSB and RO, the terminal device can select the RO associated with the downlink receive beam based on the downlink receive beam to send the PRACH or Msg A during the random access process. After detecting the PRACH or Msg A, the network device can determine the appropriate downlink receive beam direction for the terminal device.

[0054] As an example but not a limitation, FIG3A and FIG3B respectively show schematic diagrams of scenarios in which a TN and an NTN share spectrum resources.

[0055] As shown in Figure 3A, base station 1, located on the ground in a TN network, can wirelessly communicate with UE 1 within its coverage area. Base station 2, located on a satellite in an NTN network, can wirelessly communicate with UE 2 within its coverage area. The coverage area provided by base station 1 partially or completely overlaps with the coverage area provided by base station 2. If the frequency band used for communication between base station 1 and UE 1 partially or completely overlaps with the frequency band used for communication between base station 2 and UE 2, consideration must be given to how to share spectrum resources to avoid interference between TN and NTN transmissions, which could affect communication reliability.

[0056] As shown in Figure 3B, a base station 1 located on the ground in a TN network can communicate wirelessly with a UE1 within its provided communication coverage area, and a base station 2 located on the ground in an NTN network can communicate wirelessly with a UE2 within its provided communication coverage area via satellite relay. The communication coverage area provided by base station 1 partially or completely overlaps with the communication coverage area provided by base station 2, and / or the location of base station 1 has a certain correlation with the location of base station 2, such as base station 1 and base station 2 being located at the same location or the distance between base station 1 and base station 2 being less than or equal to a threshold value. If the frequency band used for communication between base station 1 and UE1 partially or completely overlaps with the frequency band used for communication between satellite and UE2, and / or if the frequency band used for communication between base station 1 and UE1 partially or completely overlaps with the frequency band used for communication between satellite and base station 2, then it is necessary to consider how to share spectrum resources to avoid mutual interference between the communication transmissions of TN and NTN, thereby affecting the reliability of communication.

[0057] To avoid transmission interference when the frequency bands used for communication partially or completely overlap, the frequency resources used by the two networks can be orthogonalized. For example, at least one of the following approaches can be considered: space division multiplexing, time division multiplexing, and frequency division multiplexing. The specific multiplexing method to be used, and how to implement it after the multiplexing method is determined, requires coordination between the network devices of the two networks. Based on the above considerations, the embodiments of this application provide the following solution.

[0058] Please refer to Figure 4, which shows a flow chart of a wireless communication method provided by an embodiment of the present application. The method is executed by a first network device and includes at least one of the following steps 410 to 420.

[0059] In step 410, the first network device receives first information sent by the second network device. The first information is used to determine whether the first network device is allowed to use the first spectrum resource for communication. The first spectrum resource is the spectrum resource used by the second network device for communication. The first network device is a network device in the first communication network. The second network device is a network device in the second communication network. The first communication network and the second communication network are different communication networks.

[0060] Accordingly, the second network device sends the first information to the first network device.

[0061] In some embodiments, the first spectrum resource is a shared spectrum resource. In some embodiments, the shared spectrum resource refers to a spectrum resource shared by the second network device and the first network device. In some embodiments, the shared spectrum resource refers to a spectrum resource shared by the second communication network and the first communication network.

[0062] In some embodiments, the first spectrum resource is an FDD (Frequency Division Duplexing) spectrum. FDD is a full-duplex communication technology used in mobile communication systems, corresponding to TDD (Time-Division Duplex). FDD uses two independent channels to transmit information downward and upward respectively. In order to prevent mutual interference between adjacent transmitters and receivers, there is a protection frequency between the two channels. FDD must use paired frequencies, relying on frequency to distinguish between uplink and downlink, and its unidirectional resources are continuous in time. When supporting symmetric services, that is, when the demand for reception and transmission is similar, FDD can make full use of the uplink and downlink spectrum, but when supporting asymmetric services, the spectrum utilization rate will be greatly reduced.

[0063] In some embodiments, the first spectrum resource is a TDD spectrum. TDD is one of the duplexing technologies used in mobile communications, corresponding to FDD. It is a technology that promptly distinguishes wireless channels and continues uplink operations during downlink operations within a frame period. TDD technology does not require paired spectrum and can utilize asymmetric spectrum that FDD cannot. Combined with the low chip rate of TD-SCDMA (Time-Division Synchronous Code Division Multiple Access), it can effectively utilize spectrum.

[0064] In some embodiments, the first spectrum resource is used for downlink communication. In some embodiments, the first spectrum resource can be used for downlink communication between a first network device in a first communication network and a second network device in a second communication network.

[0065] In some embodiments, the first spectrum resource is used for uplink communication. In some embodiments, the first spectrum resource can be used for uplink communication between a first network device in a first communication network and uplink communication between a second network device in a second communication network.

[0066] In some embodiments, the first spectrum resource is used for uplink and downlink communications. In some embodiments, the first spectrum resource can be used by a first network device for uplink and downlink communications in a first communication network, and can be used by a second network device for uplink and downlink communications in a second communication network.

[0067] In some embodiments, the first network device and the second network device use the first spectrum resource for communication in the same direction. For example, the first network device and the second network device both use the first spectrum resource for downlink communication in their respective communication networks. For example, the first network device and the second network device both use the first spectrum resource for uplink communication in their respective communication networks.

[0068] In some embodiments, the first network device and the second network device use the first spectrum resource for communication in different directions. For example, the first network device uses the first spectrum resource for uplink communication in the first communication network, and the second network device uses the first spectrum resource for downlink communication in the second communication network. For example, the first network device uses the first spectrum resource for downlink communication in the first communication network, and the second network device uses the first spectrum resource for uplink communication in the second communication network.

[0069] In some embodiments, the first information is used to determine at least one of the following:

[0070] Allowing the first network device to communicate using the first spectrum resource;

[0071] not allowing the first network device to use the first spectrum resource for communication;

[0072] a first spectrum resource sharing mode, where the sharing mode includes at least one of the following: time division multiplexing, frequency division multiplexing, and space division multiplexing;

[0073] a communication transmission direction sharing the first spectrum resource, the communication transmission direction including at least one of the following: uplink, downlink, flexible, and sidelink;

[0074] Time domain resource information allowing the first network device to use the first spectrum resource for communication;

[0075] Frequency domain resource information allowing the first network device to use the first spectrum resource for communication;

[0076] Spatial resource information allowing the first network device to use the first spectrum resource for communication;

[0077] a timing reference of the first communication network;

[0078] A timing reference of the second communication network.

[0079] In some embodiments, the timing reference of the first communication network includes a timing reference when an uplink time unit and a downlink time unit in the first communication network are aligned.

[0091] In some embodiments, when the sharing method of the first spectrum resource includes time division multiplexing, if the second time unit is configured for downlink communication in the second uplink and downlink configuration pattern, the second time unit cannot be configured for downlink communication in the first uplink and downlink configuration pattern, or the second time unit cannot be configured for uplink communication in the first uplink and downlink configuration pattern.

[0096] In some embodiments, when the sharing mode of the first spectrum resource includes frequency division multiplexing, the first frequency domain bandwidth portion and the second frequency domain bandwidth portion do not overlap in the frequency domain.

[0097] In some embodiments, the QCL configuration information is used to determine spatial resource information allowing the first network device to communicate using the first spectrum resource, and / or spatial resource information allowing the second network device to communicate using the first spectrum resource.

[0098] In some embodiments, the QCL configuration information is used to determine a first beam direction and / or a second beam direction, wherein the first beam direction is a beam direction used by the first communication network and the second beam direction is a beam direction used by the second communication network.

[0099] In some embodiments, the QCL configuration information is used to determine at least one of the following information: a first SSB set, a second SSB set, and a third SSB set; wherein the first SSB set includes part or all of the SSBs transmitted in the first communication network, the second SSB set includes part or all of the SSBs transmitted in the second communication network, and the third SSB set includes part or all of the SSBs transmitted in the second communication network received in the first communication network.

[0100] In some embodiments, the SSB transmitted in the second communication network received in the first communication network includes: the SSB transmitted in the second communication network received by the first network device; and / or the SSB transmitted in the second communication network received by the terminal device in the first communication network.

[0101] Exemplarily, the information (e.g., second information) sent by the first network device to the second network device is used to determine the first SSB set, and the information (e.g., first information) sent by the second network device to the first network device is used to determine whether one or more SSBs in the first SSB set can communicate through the first spectrum resource.

[0102] Exemplarily, the information (e.g., first information) sent by the second network device to the first network device is used to determine the second SSB set, and the first network device determines the first SSB set based on the second SSB set so that the beam directions of the SSBs in the first SSB set and the SSBs in the second SSB set are different, thereby reducing interference.

[0103] Exemplarily, the information (e.g., second information) sent by the first network device to the second network device is used to determine a third SSB set that may cause interference to the first communication network, and the second network device determines whether to allow the first network device to communicate through the first spectrum resource based on the information.

[0104] Step 420: When the first network device determines, based on the first information, that it is allowed to use the first spectrum resource for communication, the first network device uses the first spectrum resource for communication in the first communication network.

[0105] In some embodiments, the first communication network is an NTN, and the first network device is a network device in the NTN; the second communication network is a TN, and the second network device is a network device in the TN. Exemplarily, the first network device is a satellite, and the second network device is a base station. Exemplarily, the first network device is a base station in the NTN, and the second network device is a base station in the TN.

[0106] In some embodiments, the first communication network is a TN, and the first network device is a network device in the TN; the second communication network is an NTN, and the second network device is a network device in the NTN. Exemplarily, the first network device is a base station, and the second network device is a satellite. Exemplarily, the first network device is a base station in the TN, and the second network device is a base station in the NTN.

[0107] In some embodiments, before step 410 , the method further includes the following step 430 .

[0108] Step 430: The first network device sends second information to the second network device, where the second information is used to determine at least one of the following:

[0109] Requesting the second network device to use the first spectrum resource;

[0110] a timing reference of the first communication network;

[0111] A timing reference of the second communication network.

[0112] Correspondingly, the second network device receives the second information sent by the first network device.

[0113] The technical solution provided in the embodiment of the present application determines whether the first network device can use the first spectrum resource for communication through the first information sent by the second network device, so that the first network device can share the spectrum resource with the second network device, effectively avoiding or reducing interference in communication signal transmission between two or more networks sharing the spectrum resource, and improving the reliability of signal transmission.

[0114] The technical solution provided in the embodiments of the present application will be exemplified below by taking spectrum resource sharing between NTN and TN as an example.

[0115] 1. The first communication network is NTN and the second communication network is TN

[0116] In some embodiments, the first communication network is an NTN, the second communication network is a TN, the first network device is a network device in the NTN, and the second network device is a network device in the TN.

[0117] In some embodiments, the second information sent by the first network device to the second network device is used to determine at least one of the following information: requesting the second network device to use the first spectrum resources, the timing reference of the first communication network, the timing reference of the second communication network, the first offset value, the second offset value, the first ephemeris information, the first SSB set and the third SSB set.

[0118] In some embodiments, the first offset value is determined based on a round-trip delay of a communication link between a first reference point in the first communication network and a first terminal device in the first communication network.

[0119] In some embodiments, the second offset value is determined based on a round-trip delay of a communication link between the first reference point and the first network device in the first communication network.

[0120] In some embodiments, the first ephemeris information is ephemeris information in the first communication network. For example, the first ephemeris information is ephemeris information of a serving satellite in the first communication network.

[0121] In some embodiments, the first set of SSBs includes some or all of the SSBs transmitted in the first communication network.

[0122] In some embodiments, the third SSB set includes some or all of the SSBs transmitted in the second communication network that are received in the first communication network.

[0123] In some embodiments, the SSB transmitted in the second communication network and received in the first communication network includes:

[0124] An SSB transmitted in the second communication network and received by the first network device; and / or

[0125] The SSB transmitted in the second communication network is received by the terminal device in the first communication network.

[0126] In some embodiments, the first information is used to determine at least one of the following information: allowing the first network device to use the first spectrum resource for communication, not allowing the first network device to use the first spectrum resource for communication, the sharing method of the first spectrum resource, the communication transmission direction of sharing the first spectrum resource, time domain resource information allowing the first network device to use the first spectrum resource for communication, frequency domain resource information allowing the first network device to use the first spectrum resource for communication, spatial domain resource information allowing the first network device to use the first spectrum resource for communication, the timing reference of the first communication network, the timing reference of the second communication network, the first location information, and the second SSB set.

[0127] In some embodiments, the first location information is location information of the second network device.

[0128] In some embodiments, the second set of SSBs includes some or all of the SSBs transmitted in the second communication network.

[0129] For example, referring to Figure 3 , base station 1 is a second network device, UE1 is a terminal device in the second communication network, and the second communication network is a TN network. Base station 2 is a first network device, UE2 is a terminal device in the first communication network, and the first communication network is an NTN network. In Figure 3A , base station 1 in the TN network can communicate with UE1 using a first spectrum resource. Base station 2 receives first information sent by base station 1, which is used to determine whether base station 2 in the NTN network can communicate with UE2 using the first spectrum resource. In Figure 3B , base station 1 in the TN network can communicate with UE1 using the first spectrum resource. Base station 2 receives first information sent by base station 1, which is used to determine whether a satellite in the NTN network can communicate with UE2 using the first spectrum resource.

[0130] Base station 2 sends second information to base station 1. This second information is used by base station 2 to request base station 1 to use the first spectrum resource. This second information can also be used to determine at least one of a first offset value, a second offset value, first ephemeris information, a timing reference of the first communication network, and a first SSB set. The first offset value is determined based on the round-trip delay of the communication link between a reference point in the NTN network and a terminal device in the NTN network; the second offset value is determined based on the round-trip delay of the communication link between the reference point in the NTN network and base station 2; the first ephemeris information is ephemeris information of a satellite in the NTN network; and the timing reference of the first communication network is the timing reference in the NTN network.

[0131] In some embodiments, in the example of FIG3A , the reference point in the NAN network is on the satellite, and in the example of FIG3B , the reference point in the NTN network is on the communication link between base station 2 and the satellite. In other words, in the example of FIG3B , the reference point in the NTN network can be any point on the communication link between base station 2 and the satellite (including base station 2 and the satellite).

[0132] Base station 1 determines first information, where the first information is used to determine whether base station 2 can use the first spectrum resources for communication or the spectrum resources in the first spectrum resources that can be used for communication with base station 2. The first information may be determined based on second information sent by base station 2, or may not be determined based on the second information.

[0133] Exemplarily, the first information is used to indicate at least one of the following information: a sharing method for the first spectrum resource, a communication transmission direction for sharing the first spectrum resource, a time unit configuration pattern, and a timing reference of the second communication network (e.g., a timing reference of a TN network). As shown in FIG5 , a schematic diagram of the time unit configuration pattern is provided. The sharing method for the first spectrum resource is time division multiplexing, and the communication transmission direction for sharing the first spectrum resource is downlink. The time unit configuration pattern is used to configure the TN network to use even frames on the first spectrum resource, and / or the NTN network to use odd frames on the first spectrum resource. The even or odd frames are determined based on the timing reference of the TN network (i.e., the time unit configuration pattern corresponds to the timing reference of the TN network). After receiving the first information, base station 2 can determine the downlink time units that can be used by the NTN network on the first spectrum resource based on the timing reference of the TN network, the timing reference of the NTN network, the first offset value, and the second offset value.

[0134] As shown in Figure 5, odd frames and even frames are determined based on the timing reference of the TN network, while the timing reference of the NTN network is aligned at the reference point of the NTN network, and the timing references of the two are different. Therefore, it is necessary to determine the downlink time unit that can be used by the NTN network on the first spectrum resource based on the timing reference of the TN network and the timing reference of the reference point of the NTN network. Exemplarily, the downlink time unit determined based on the timing reference of the TN network is aligned with the downlink time unit of a terminal device in the NTN network (that is, the downlink time units with the same number are aligned). Based on the above information, base station 2 can determine the time unit that can be used for downlink communication in the downlink time unit of base station 2 on the first spectrum resource. It should be noted that the downlink time unit of the terminal device in Figure 5 can be the downlink time unit of UE2 (a certain terminal device), or it can be the downlink time unit of a terminal device at a predefined location, such as a virtual terminal device. Exemplarily, the location of the virtual terminal device can be the location of base station 1.

[0135] Figure 6 shows another schematic diagram of the time unit configuration pattern. As shown in Figure 6, the sharing method of the first spectrum resource is time division multiplexing, and the communication transmission direction of the shared first spectrum resource is uplink. The time unit configuration pattern is used to configure the TN network to use even frames on the first spectrum resource, and / or the NTN network to use odd frames on the first spectrum resource, wherein the even frames or odd frames are determined based on the timing reference of the TN network (i.e., the time unit configuration pattern corresponds to the timing reference of the TN network). After receiving the first indication information, base station 2 can determine the uplink time units that the NTN network can use on the first spectrum resource based on the timing reference of the TN network, the timing reference of the NTN network, the first offset value, and the second offset value.

[0136] As shown in Figure 6, odd frames and even frames are determined based on the timing reference of the TN network, while the timing reference of the NTN network is aligned at the reference point of the NTN network, and the timing references of the two are different. Therefore, it is necessary to determine the uplink time unit that can be used by the NTN network on the first spectrum resource based on the timing reference of the TN network and the timing reference of the reference point of the NTN network. Exemplarily, the uplink time unit determined based on the timing reference of the TN network is aligned with the uplink time unit of a terminal device in the NTN network (that is, the uplink time units with the same number are aligned). Based on the above information, base station 2 can determine the time unit that can be used for uplink communication in the uplink time unit of base station 2 on the first spectrum resource. It should be noted that the uplink time unit of the terminal device in Figure 6 can be the uplink time unit of UE2 (a certain terminal device), or it can be the uplink time unit of a terminal device at a predefined location, such as a virtual terminal device. Exemplarily, the location of the virtual terminal device can be the location of base station 1.

[0137] Exemplarily, the first information is used to determine at least one of the following: whether the first spectrum resource can be used, the sharing method of the first spectrum resource, and the communication transmission direction for sharing the first spectrum resource. The third SSB set in the second information is used to determine the SSBs in the TN network that can be received by the UE in the NTN network. The QCL configuration information can be determined based on the third SSB set in the second information. For example, the SSBs transmitted in the TN network are SSB0, SSB1, SSB2, and SSB3, and the SSBs in the TN network that can be received by the UE in the NTN network are SSB2 and SSB3. Therefore, the UE in the NTN network notifies base station 2 of this information, and base station 2 notifies base station 1 of this information, indicating that the third SSB set includes SSB2 and SSB3. After receiving this third SSB set, base station 1 decides to share the first spectrum resource with the NTN network. Therefore, it updates the SSBs transmitted in the TN network to SSB0 and SSB1 and indicates in the first information that base station 2 can use the first spectrum resource, the sharing method of the first spectrum resource, such as spatial domain multiplexing, and the communication transmission direction for sharing the first spectrum resource, such as uplink or downlink. Alternatively, base station 1 may also decide not to share the first spectrum resource with the NTN network, that is, to indicate in the first information that base station 2 cannot use the first spectrum resource.

[0138] Base station 2 receives first information sent by base station 1, where the first information is used to determine whether the first spectrum resource or spectrum resources in the first spectrum resource that can be used for communication with base station 2 can be used. If the first spectrum resource can be used, base station 2 determines the spectrum resources in the first spectrum resource that can be used for communication with base station 2 based on the first information, and communicates with UE 2 using the spectrum resources in the first spectrum resource that can be used for communication with base station 2.

[0139] 2. The first communication network is TN, and the second communication network is NTN

[0140] In some embodiments, the first communication network is a TN, the second communication network is an NTN, the first network device is a network device in the TN, and the second network device is a network device in the NTN.

[0141] In some embodiments, the first information is used to determine at least one of the following information: allowing the first network device to use the first spectrum resource for communication, not allowing the first network device to use the first spectrum resource for communication, the sharing method of the first spectrum resource, the communication transmission direction of sharing the first spectrum resource, time domain resource information allowing the first network device to use the first spectrum resource for communication, frequency domain resource information allowing the first network device to use the first spectrum resource for communication, spatial domain resource information allowing the first network device to use the first spectrum resource for communication, the timing reference of the first communication network, the timing reference of the second communication network, the third offset value, the fourth offset value, the second ephemeris information and the second SSB set.

[0142] In some embodiments, the third offset value is determined based on a round-trip delay of a communication link between a second reference point in the second communication network and a second terminal device in the second communication network.

[0143] In some embodiments, the fourth offset value is determined based on a round-trip delay of a communication link between the second reference point and the second network device in the second communication network.

[0144] In some embodiments, the second ephemeris information is ephemeris information in the second communication network. For example, the second ephemeris information is ephemeris information of a serving satellite in the second communication network.

[0145] In some embodiments, the second set of SSBs includes some or all of the SSBs transmitted in the second communication network.

[0146] In some embodiments, the second information sent by the first network device to the second network device is used to determine at least one of the following information: requesting the second network device to use the first spectrum resources, the timing reference of the first communication network, the timing reference of the second communication network, the second location information, the first SSB set, and the third SSB set.

[0147] In some embodiments, the second location information is location information of the first network device.

[0148] In some embodiments, the first set of SSBs includes some or all of the SSBs transmitted in the first communication network.

[0149] In some embodiments, the third SSB set includes some or all of the SSBs transmitted in the second communication network that are received in the first communication network.

[0150] In some embodiments, the SSB transmitted in the second communication network and received in the first communication network includes:

[0151] An SSB transmitted in the second communication network and received by the first network device; and / or

[0152] The SSB transmitted in the second communication network is received by the terminal device in the first communication network.

[0153] For example, please refer to the scenario diagram of shared spectrum resources shown in Figure 3A or Figure 3B. Base station 1 is a first network device, UE1 is a terminal device in the first communication network, and the first communication network is a TN network; base station 2 is a second network device, UE2 is a terminal device in the second communication network, and the second communication network is an NTN network. In Figure 3A, base station 2 in the NTN network can use the first spectrum resource to communicate with UE2, and base station 1 receives the first information sent by base station 2. The first information is used to determine whether base station 1 in the TN network can use the first spectrum resource to communicate with UE1. In Figure 3B, a satellite in the NTN network can use the first spectrum resource to communicate with UE2. Base station 1 receives the first information sent by base station 2. The first information is used to determine whether base station 1 in the TN network can use the first spectrum resource to communicate with UE1.

[0154] Base station 1 sends second information to base station 2, where base station 1 requests base station 2 to use the first spectrum resource. The second information can also be used to determine one of second location information and a timing reference of the first communication network. The second location information is the location information of base station 1, and the timing reference of the first communication network is a timing reference in the TN network.

[0155] Base station 2 determines first information, where the first information is used to determine whether base station 1 can use the first spectrum resources for communication or the spectrum resources in the first spectrum resources that can be used for communication with base station 1. The first information can be determined based on second information sent by base station 1, or can be determined based on the second information.

[0156] Exemplarily, the first information is used to determine at least one of the following: the sharing method of the first spectrum resource, the communication transmission direction for sharing the first spectrum resource, a time unit configuration pattern, and the timing reference of the second communication network (e.g., the timing reference of the NTN network). Figure 7 shows a schematic diagram of the time unit configuration pattern. As shown in Figure 7, the sharing method of the first spectrum resource is time division multiplexing, and the communication transmission direction for sharing the first spectrum resource is downlink. The time unit configuration pattern is used to configure the TN network to use even frames on the first spectrum resource, and / or the NTN network to use odd frames on the first spectrum resource. The even or odd frames are determined based on the timing reference of the NTN network (i.e., the time unit configuration pattern corresponds to the timing reference of the NTN network). Exemplarily, the timing reference of the NTN network is determined by the downlink time unit of a terminal device in the NTN network. The terminal device can be a terminal device in the NTN network or a downlink time unit of a terminal device at a predefined location, such as a virtual terminal device. Exemplarily, the location of the virtual terminal device can be the location of base station 1. After receiving the first information, base station 1 can determine the downlink time unit that can be used by the TN network on the first spectrum resource according to the timing reference of the NTN network and the timing reference of the TN network.

[0157] Figure 8 provides another schematic diagram of a time unit configuration pattern. As shown in Figure 8 , the first spectrum resource is shared using time division multiplexing, and the communication transmission direction for sharing the first spectrum resource is uplink. The time unit configuration pattern is used to configure the TN network to use even frames on the first spectrum resource, and / or the NTN network to use odd frames on the first spectrum resource, wherein the even or odd frames are determined based on the timing reference of the NTN network (i.e., the time unit configuration pattern corresponds to the timing reference of the NTN network). Exemplarily, the timing reference of the NTN network is determined by the uplink time unit of a terminal device in the NTN network. The terminal device can be a terminal device in the NTN network, or it can be an uplink time unit of a terminal device at a predefined location, such as a virtual terminal device. Exemplarily, the location of the virtual terminal device can be the location of base station 1. After receiving the first indication information, base station 1 can determine the uplink time unit that the TN network can use on the first spectrum resource based on the timing reference of the NTN network and the timing reference of the TN network.

[0158] Exemplarily, the first information is used to determine at least one of the following information: whether the first spectrum resource can be used, the sharing method of the first spectrum resource, and the communication transmission direction of sharing the first spectrum resource. The third SSB set in the second information is used to determine the SSBs in the NTN network that base station 1 can receive, and the QCL configuration information can be determined based on the third SSB set in the second information. For example, the SSBs transmitted in the NTN network are SSB0, SSB1, SSB2, and SSB3, and the SSB in the NTN network that base station 1 can receive is SSB2. Therefore, base station 1 notifies base station 2 of this information, that is, the third SSB set includes SSB2. After receiving the third SSB set, base station 2 decides to share the first spectrum resource with the TN network, and therefore updates the SSBs transmitted in the NTN network to SSB0, SSB1, and SSB3, and indicates in the first information that base station 1 can use the first spectrum resource, the sharing method of the first spectrum resource, such as spatial domain multiplexing, and the communication transmission direction of sharing the first spectrum resource, such as uplink or downlink. Alternatively, base station 2 may also decide not to share the first spectrum resource with the TN network, that is, to indicate in the first information that base station 1 cannot use the first spectrum resource.

[0159] Exemplarily, the first information is used to determine at least one of the following information: whether the first spectrum resource can be used, and the communication transmission direction of the shared first spectrum resource. The second location information in the second information is used to determine the location of the base station 1, and the QCL configuration information can be determined based on the second location information in the second information. For example, the base station 2 in the NTN network can determine the beam direction that may interfere with the communication of the base station 1 based on the location information of the base station 1. If the base station 2 decides to share the first spectrum resource with the TN network, then the base station 2 may not transmit in the beam direction that may interfere with the communication of the base station 1, and indicate in the first information that the base station 1 can use the first spectrum resource and the communication transmission direction of the shared first spectrum resource, such as uplink or downlink. If the base station 2 decides not to share the first spectrum resource with the TN network, it indicates in the first information that the base station 1 cannot use the first spectrum resource.

[0160] Base station 1 receives first information sent by base station 2, where the first information is used to determine whether the first spectrum resource or spectrum resources within the first spectrum resource that can be used for communication with base station 1 can be used. If the first spectrum resource can be used, base station 1 determines the spectrum resources within the first spectrum resource that can be used for communication with base station 1 based on the first information, and communicates with UE 1 using the spectrum resources within the first spectrum resource that can be used for communication with base station 1.

[0161] Through the above method, spectrum resource sharing between the TN network and the NTN network is achieved, which can avoid or reduce interference in communication signal transmission between two or more networks sharing spectrum resources and improve the reliability of signal transmission.

[0162] In the above method embodiments, the technical solution of this application is described only from the perspective of the interaction between the first network device and the second network device. The above steps performed by the first network device can be independently implemented as a wireless communication method on the first network device side, and the above steps performed by the second network device can be independently implemented as a wireless communication method on the second network device side.
