[0036] The following will be combined with the drawings in the present disclosure to clearly and completely describe the technical solutions in the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0037] It should be noted that, in the present disclosure, words such as "exemplary" or "for example" are used to indicate examples, illustrations or descriptions. Any embodiment or design described as "exemplary" or "for example" in the present disclosure should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.

[0038] In the following, the terms "first" and "second" are used for descriptive purposes only and are not to be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features.

[0039] In the description of the present disclosure, unless otherwise specified, " / " means "or", for example, A / B can mean A or B. "And / or" in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships, for example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. In addition, "at least one" means one or more, and "a plurality" means two or more.

[0040] The following is an explanation of the technical terms used in the embodiments of the present disclosure.

[0041] 1. NTN

[0042] NTN (also known as satellite network) mainly refers to a communication network based on non-ground infrastructure, which mainly provides communication services through satellites, unmanned aerial vehicles (UAVs), high altitude platforms (HAPs), etc. In NTN, satellites can be regarded as base stations, and terminals can connect to satellites to achieve communication through satellites. In areas that cannot be covered by ground base stations, terminals can connect to satellites for communication, thereby achieving full coverage of the connection.

[0043] Figure 1 A schematic diagram of the structure of an NTN is shown. Exemplarily, the satellite 101 can be regarded as a base station and a terminal 102 on the ground for communication connection, and the link between the satellite 101 and the terminal 102 is a service link. In addition, the satellite 101 is connected to the access network device 103 for communication, and the link between the satellite 101 and the access network device 103 is a feeder link. The satellite 101 is public for all terminals in the same cell. Among them, the access network device 103 includes a base station and a gateway.

[0044] 2. TN

[0045] TN mainly refers to communication networks based on ground infrastructure. They provide communication services through base stations, antennas, and wireless / wired transmission equipment. For example, the third generation universal mobile telecommunications system (3G UMTS) and 4G LTE are both TN networks. The fifth generation mobile communication system (5th Generation New Radio, 5G NR) can support both TN and NTN.

[0046] 3. Spectrum Resources

[0047] In order to provide seamless coverage for users in various regions such as the sky, air, land, and sea, multiple types of communication systems are usually required to jointly provide services. These communication systems often use dedicated spectrum for communication. In the embodiments of the present disclosure, the above-mentioned multiple types of communication systems may include TN and NTN.

[0048] In wireless communication, spectrum resources are very important transmission resources and are the key to the smooth operation of wireless communication systems. For example, NTN (also known as satellite network) and TN usually have exclusive allocation of dedicated spectrum resources. However, spectrum resources are limited. With the rapid development of wireless communication technology, available spectrum resources are becoming increasingly exhausted. Therefore, how to improve the utilization rate of spectrum resources is a technical problem that needs to be solved urgently.

[0049] In addition, for NTN and TN, how to improve users' overall connection experience (for example, for remote, unserved or underserved areas) is also a technical problem that needs to be solved urgently.

[0050] To solve the above technical problems, the embodiments of the present disclosure provide a wireless network communication method, whereby a terminal can communicate with a network device of the first type of communication and / or a network device of the second type of communication on a target spectrum. The target spectrum is a frequency domain resource used by the first type of communication and the second type of communication. In this way, there is no need to configure separate frequency domain resources for the first type of communication and the second type of communication, respectively, thereby saving spectrum resources and improving the utilization rate of spectrum resources.

[0051] The wireless network communication method provided by the embodiment of the present disclosure can be applied to Figure 2 In the communication system, Figure 2 As shown, the communication system includes: a terminal 201, a network device 202 for first-type communication and a network device 203 for second-type communication.

[0052] The terminal 201 is connected to the network device 202 of the first type of communication and the network device 203 of the second type of communication respectively. The network device 202 of the first type of communication and the network device 203 of the second type of communication are connected to each other.

[0053] In a possible implementation, one of the first type of communication and the second type of communication may be TN and the other may be NTN. For example, when the first type of communication is NTN and the second type of communication is TN, the network device 202 of the first type of communication may be a base station, access network equipment, etc., and the network device 203 of the second type of communication may be a base station, a drone, a high-altitude platform, etc. Figure 2 The following description is made by taking the network device 202 for the first type of communication as a base station and the network device 203 for the second type of communication as a satellite as an example.

[0054] In the embodiment of the present disclosure, the terminal 201 can communicate with the network device 202 for the first type of communication and / or the network device 203 for the second type of communication on the target spectrum. Since the target is the frequency domain resources used by the first type of communication and the second type of communication, there is no need to configure separate frequency domain resources for the first type of communication and the second type of communication, respectively, thereby saving frequency domain resources and improving resource utilization.

[0055] It should be noted that Figure 2 This is just an exemplary framework diagram. Figure 2 The number of devices included in the Figure 2 In addition to the devices shown, the communication system may also include other devices, such as relay nodes.

[0056] The application scenarios of the embodiments of the present disclosure are not limited. The system architecture and business scenarios described in the embodiments of the present disclosure are intended to more clearly illustrate the technical solutions of the embodiments of the present disclosure, and do not constitute a limitation on the technical solutions provided by the embodiments of the present disclosure. It is known to those skilled in the art that with the evolution of network architecture and the emergence of new business scenarios, the technical solutions provided by the embodiments of the present disclosure are also applicable to similar technical problems.

[0057] The wireless network communication method provided by the embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings.

[0058] The wireless network communication method provided by the embodiment of the present disclosure can be applied to Figure 2 Terminal 201 in the communication system shown. Figure 3 A schematic diagram showing a process of a wireless network communication method Figure 1 ,like Figure 3 As shown, the wireless network communication method includes the following S301.

[0059] S301 : Communicate with a first-category communication network device and / or a second-category communication network device on a target spectrum.

[0060] The target spectrum is a frequency domain resource used by the first type of communication and the second type of communication.

[0061] On the target spectrum, the terminal can send signals for the first type of communication or the second type of communication, so that the first type of communication and the second type of communication share the frequency domain resources. In this way, there is no need to configure spectrum resources for the first type of communication and the second type of communication respectively, thereby saving spectrum resources and improving spectrum resource utilization.

[0062] However, when the first and second type of communications transmit signals through the target spectrum, the terminal can connect to either the cell of the first type of communication or the cell of the second type of communication. Therefore, how to switch between the cells of the first type of communication and the cells of the second type of communication is a difficult problem.

[0063] It should be pointed out that, at present, when a terminal switches between multiple cells, it can perform conditional switching (CHO) to switch to a candidate cell based on a trigger condition, and the trigger condition may include: event A4, a time-based trigger condition, and a location-based trigger condition. It should be understood that the time-based trigger condition and the location-based trigger condition can be configured together with the measurement-based trigger condition. The position is determined by the distance between the terminal and the reference position, and the time is determined by T1 and T2, where T1 is the time point when the measurement condition is met, and T2 is the time period starting from T1.

[0064] In the following, the first type of communication and the second type of communication are described by taking a non-terrestrial communication network (hereinafter referred to as NTN) and a terrestrial communication network (hereinafter referred to as TN) as an example.

[0065] In a possible implementation, TN and NTN sharing the same frequency domain resources may include: TN / NTN sharing all resources used by NTN / TN, or TN / NTN sharing part of the resources used by NTN / TN. For example, NTN performs uplink (UL) transmission on frequency band F1 and downlink (DL) transmission on frequency band F2. The TN sharing NTN frequency band F1 to perform TN UL / DL transmission mentioned in the embodiments of the present disclosure includes the above two cases, namely: 1) TN shares the entire bandwidth of frequency band F1 to perform TN UL / DL transmission, 2) TN shares part of the bandwidth in frequency band F1 to perform TN UL / DL transmission.

[0066] In some embodiments, Figure 4 A schematic diagram of a process of switching between an NTN cell and a TN cell is shown. Figure 3 ,like Figure 4 As shown, the method provided by the embodiment of the present disclosure also includes:

[0067] S401. Determine a target cell that meets a cell switching condition from multiple candidate cells.

[0068] The multiple candidate cells include cells of a terrestrial communication network and cells of a non-terrestrial communication network.

[0069] The terminal may determine multiple neighboring cells as multiple candidate cells, and determine a target cell that meets the cell switching condition from the multiple candidate cells, for example, determine a cell with the highest signal strength from the multiple candidate cells as the target cell.

[0070] In a possible implementation, before the above S401, the method provided by the embodiment of the present disclosure may further include: receiving a conditional switching command (or a conditional switching parameter).

[0071] The conditional switching command is used to configure the cell switching condition. Optionally, the conditional switching command may be sent by a network device of a terrestrial communication network or a network device of a non-terrestrial communication network.

[0072] In some cases (e.g., signal quality is poor), the TN network device or the NTN network device may send a conditional switching command to the terminal so that the terminal configures the cell switching condition. In this way, when the cell switching condition is met, the terminal can switch from the current cell to the target cell. For example, when the cell currently connected to the terminal is a TN cell, and the terminal moves to the edge of the TN cell, the TN network device (e.g., a base station) may determine that the signal quality is poor based on the measurement results reported by the terminal, and thus send a conditional switching command to the terminal so that the terminal switches from the TN cell to the NTN cell, thereby ensuring the communication quality.

[0073] It should be pointed out that in order to achieve mobility in NTN, NTN network equipment can carry the satellite ephemeris of the service cell and neighboring cell required to access the target NTN cell in the conditional switching command. The terminal supports the mobility of NTN and TN quality inspection, that is, switching from NTN cell to TN cell, and from TN cell to NTN cell, but there is no need to connect NTN and TN at the same time. In addition, it can also support mobility between wireless access technologies based on different orbits (such as geostationary satellite orbit (GSO) and non geostationary satellite orbit (NGSO) at different altitudes).

[0074] S402: Switch from the source cell to the target cell.

[0075] After determining the target cell, the terminal may switch from the source cell to the determined target cell, for example, from a TN cell to an NTN cell, or from an NTN cell to a TN cell, or from one TN cell to another TN cell.

[0076] For example, Figure 5 FIG. 1 shows a schematic diagram of a cell switching. Figure 5 As shown, the satellite in the NTN is connected to the terminal in communication. The terminal is also connected to the TN base station in communication. When the terminal is connected to the NTN cell, the satellite in the NTN can send a conditional switching command to the terminal. In this way, when the conditional switching command is met, the terminal can switch from the NTN cell to the TN base station to obtain the TN cell.

[0077] In a possible implementation, in the above S401, the terminal determines the target cell that meets the cell switching condition from the multiple candidate cells specifically includes: determining the target cell from the multiple candidate cells based on the respective priorities of the multiple candidate cells. Optionally, the priority of selecting the NTN cell may be higher than the priority of selecting the TN cell, and the priority of selecting the TN cell may be higher than the priority of selecting the NTN cell.

[0078] The following describes how the terminal prioritizes between TN cells and NTN cells in various ways:

[0079] Solution 1: Use the traditional cell selection mechanism (for example, the priority between NTN cells and TN cells is the same), or other cell switching mechanisms can be selected. Since the switching between NTN cells and TN cells is a co-frequency switching, other trigger conditions besides A4 are required in the trigger conditions, such as A3 event.

[0080] Solution 2: The priority satisfies any one of the following relationships: the priority of switching to the NTN cell is higher than the priority of switching to the TN cell; the priority of switching to the NTN cell is lower than the priority of switching to the TN cell.

[0081] For NTN cells with a higher priority than TN cells, when the terminal's measurement results of the signal strength of NTN cells and TN cells (e.g., reference signal received power (RSRP) / reference signal received quality (RSRQ)) and / or other factors for cell selection are the same, the terminal prioritizes staying / switching to the NTN cell; for NTN cells with a lower priority than the priority of TN cells, when the terminal's measurement results of NTN cells and TN cells and / or other factors for cell selection are the same, the terminal prioritizes staying / switching to the TN cell. Alternatively, a low-priority cell will be selected only when a high-priority cell is not available (e.g., RSRP / RSRQ is prohibited or below a threshold, etc.).

[0082] In solution 2, if the priority of the NTN cell is different from that of the TN cell, the priority between the NTN cell and the TN cell can be determined by at least one of the following methods:

[0083] Solution 2-1: The priority between the NTN cell and the TN cell is determined by the source of the target spectrum. It should be understood that the source of the target spectrum is the network to which the target spectrum belongs. When the target spectrum originates from the NTN, the priority of switching to the NTN cell is higher than the priority of switching to the TN cell. When the target spectrum originates from the TN, the priority of switching to the TN cell is higher than the priority of switching to the NTN cell.

[0084] For example, when the target spectrum is a frequency domain resource allocated to TN (i.e., the target spectrum is a dedicated spectrum for transmitting TN signals), and NTN shares the frequency domain resource allocated to TN, when both the NTN cell and the TN cell are available, the priority of the NT cell is higher than the priority of the NTN cell. Conversely, when the target spectrum is a frequency domain resource allocated to NTN (i.e., the target spectrum is a dedicated spectrum for transmitting NTN signals), the priority of NTN is higher than the priority of TN.

[0085] It should be noted that an NTN cell will overlap multiple TN cells. NTN cells are potentially available in a larger coverage area, while TN cells have a relatively small coverage area. Therefore, when TN cells have a higher priority, frequent switching may be required. Therefore, the priority of NTN cells can be higher than that of TN cells. However, due to the poor reliability of NTN, especially in indoor or invisible areas, and some NTN cells are also mobile, which affects the reliability of NTN cells in various service scenarios. Therefore, the priority of selecting TN cells can be higher than that of NTN cells.

[0086] Solution 2-2: The priority between the NTN cell and the TN cell may be predefined, for example, by selecting a communication priority higher than another communication priority in a predefined manner.

[0087] Solution 2-3, the priority between the NTN cell and the TN cell can be configured on the network side. Optionally, the network side can be a base station in the TN, a satellite in the NTN, etc. The network side can reuse existing resources or introduce virtual resources to indicate the priority between the terminal NTN cell and the TN cell through a variety of methods such as master information block (MIB), system information block (SIB) 1, open system interconnection (OSI) or radio resource control (RRC) signaling.

[0088] Solution 2-4: In the cell switching conditions (or cell switching criteria, triggering conditions, such as A4 or A5 events), different threshold values ​​are used for NTN cells and TN cells. In this way, the cell switching conditions with lower (or higher) threshold values ​​are more likely to be met, and it is easier to switch to the corresponding cell, so that the priorities of NTN cells and TN cells can be different.

[0089] In a possible implementation manner, before determining the target cell, a configuration parameter of the conditional switching command may also be received, where the configuration parameter includes at least one of the following: a threshold value and an offset value.

[0090] The threshold values include a first threshold value corresponding to the NTN cell and a second threshold value corresponding to the TN cell. Optionally, the first threshold value is different from the second threshold value.

[0091] For example, when a terminal in an NTN cell measures a neighboring TN cell, the signal strength of the neighboring cell needs to be higher than the threshold value A1 (i.e., the second threshold value mentioned above), then it switches to the TN cell. When a terminal in a TN cell measures a neighboring NTN cell, the signal strength of the neighboring cell needs to be higher than the threshold value A2 (i.e., the first threshold value mentioned above), then it switches to the NTN cell. If the first threshold value is lower than the second threshold value, the terminal is more likely to switch to the NTN cell, so that the priority of the NTN cell can be higher than that of the TN cell.

[0092] Another example is that when the signal strength of the NTN cell is lower than the threshold value B1 and the signal strength of the adjacent TN cell is higher than the threshold value B2, the terminal switches from the NTN cell to the TN cell. When the signal strength of the TN cell is lower than the threshold value B3 and the signal strength of the adjacent NTN cell is higher than the threshold value B4, the terminal switches from the TN cell to the NTN cell. If the priority of the TN cell is higher than that of the NTN cell, then B3 < B1 and / or B2 > B4. Among them, B3 and B2 are the first threshold values, and B1 and B4 are the second threshold values.

[0093] Solution 2-5: In the cell handover condition (or cell handover criterion, trigger condition, such as A3, A4 or A5 event), different offset values are used for the NTN cell and the TN cell. It should be understood that the offset value (also called offset). In the related art, the same offset value is used for different cells. For example, different Ofn and / or Ocn are used for the NTN cell and the TN cell. Ofn is the measurement object specific offset of the neighboring cell reference signal. Ocn is the neighboring cell level specific offset. The NTN cell uses Ofn1 and Ocn1, and the TN cell uses Ofn2 and Ocn2.

[0094] In a possible implementation, the offset value includes a first offset value corresponding to the NTN cell and a second offset value corresponding to the TN cell. Optionally, the first offset value is different from the second offset value.

[0095] In this case, by setting different offset values for the NTN cell and the TN cell, in this way, the cell with a higher (or lower) offset value can meet the cell handover condition faster and can be preferentially switched to this cell, thus realizing the difference in priority between the NTN cell and the TN cell.

[0096] Solution 2-6: In the cell switching conditions (or cell switching criteria, trigger conditions, such as A3, A4 or A5 events), add new offset values ​​to the NTN cell and the TN cell. For example, if it is necessary to ensure that the priority of the TN cell is higher than the priority of the NTN cell, when the terminal in the NTN cell measures the signal strength of the neighboring TN cell, the new offset value can be subtracted from the neighboring cell signal strength. If the neighboring cell signal strength minus the new offset value is still higher than the signal strength of the current cell, it can be switched to the TN cell. In other words, the NTN cell will only be selected when the signal strength of the NTN cell is significantly better than that of the TN cell. If it is necessary to ensure that the priority of the NTN cell is higher than that of the TN cell, the TN cell will only be selected when the signal strength of the TN cell is significantly better than that of the NTN cell.

[0097] In a possible implementation, the offset value includes N first offset values ​​corresponding to the NTN cell and M second offset values ​​corresponding to the TN cell, and N and M are both positive integers. Optionally, N is different from M. For example, N first offset values ​​can be configured for the NTN cell, and M second offset values ​​can be configured for the TN cell. In this way, if M is greater than N, and the values ​​of the M first offset values ​​are greater than (or less than) the values ​​of the N second offset values, then during the cell switching process, it is easier for the terminal to switch to the TN cell (or NTN cell), thereby achieving a higher priority for the TN cell (or NTN cell).

[0098] Solution 2-7: The priority of the NTN cell and the TN cell can be determined by the terminal side. For example, when the terminal can connect to the NTN cell or the TN cell, the terminal can independently decide to access the NTN cell or the TN cell.

[0099] In addition, when NTN and TN share the same target spectrum, how to carry out resource collaboration and interference avoidance between NTN and TN is also an urgent problem to be solved.

[0100] It should be noted that NTN (or satellite system) can use frequency division duplex or frequency division multiplexing (FDD) mode, that is, NTN uses different frequency bands for uplink and downlink. Generally, the NTN frequency band can be the FDD frequency band. If NTN uses time division duplex or time division multiplexing (TDD) mode, a protection interval is required. For example, LEO in a 600km orbit requires a protection interval of 2*7ms, while GEO requires a protection interval of 2*270. In addition, some LEO / HAPS systems support TDD mode.

[0101] When NTN and TN share the target spectrum, multiple types of interference may exist. Table 1 shows a schematic table of eight types of interference. For FDD NTN and FDD TN share the target spectrum, and NTN downlink shares spectrum F1 in the target spectrum with TN downlink, and NTN uplink shares spectrum F2 in the target spectrum with TN uplink, then the main interference is same-link interference (SLI), that is, I1-I4 in Table 1, uplink interferes with uplink, and downlink interferes with downlink. If NTN downlink shares spectrum F1 in the target spectrum with TN uplink, and NTN uplink shares spectrum F2 in the target spectrum with TN downlink, then the main interference is cross-link interference (CLI), that is, I5-I8 in Table 1. In addition, if NTN is based on TDD transmission, due to the long delay of satellite communication, I1-I8 in Table 1 may all exist.

[0102] Table 1

[0103] Interference Type Disruptor The disturbed Remark I1 TN DL NTN DL SLI, such as Figure 6 (a) I2 NTN DL TN DL SLI, such as Figure 6 (a) I3 TN UL NTN UL SLI, such as Figure 6 (b) I4 NTN UL TN UL SLI, such as Figure 6 (b) I5 TN UL NTN DL CLI, such as Figure 7 (c) I6 NTN DL TN UL CLI, such as Figure 7 (c) I7 TN DL NTN UL CLI, such as Figure 7 (d) I8 NTN UL TN DL CLI, such as Figure 7 (d)

[0104] The interference types include I1-I8, the interferer is the communication causing the interference, the interfered party is the communication being interfered with, and the note is that the interference is SLI or CLI.

[0105] Figure 6 and Figure 7 The interference diagrams of two types of NTN and TN are shown respectively. Figure 6 As shown, the spectrum F1 in the target spectrum is used for TN uplink transmission and NTN uplink transmission, and the spectrum F2 in the target spectrum is used for TN downlink transmission and NTN downlink transmission. Figure 6 Including (a) and (b). Wherein, (a) and (b) both include satellites, NTN terminals (or UEs), TN terminals (or UEs), and base stations. In (a), the satellite and the NTN terminal can implement NTN downlink transmission, and the base station and the TN terminal can implement TN downlink transmission. The TN downlink transmission of the base station can cause interference of type I1 (i.e., I1 in Table 1) to the NTN downlink transmission of the NTN terminal. The NTN downlink transmission of the satellite can cause interference of type I2 (i.e., I2 in Table 1) to the TN downlink transmission of the TN terminal. In (b), the satellite and the NTN terminal can implement NTN uplink transmission, and the base station and the TN terminal can implement TN uplink transmission. The TN uplink transmission of the base station can cause interference of type I3 ​​(i.e., I3 in Table 1) to the NTN uplink transmission of the NTN terminal. The NTN uplink transmission of the satellite can cause interference of type I4 (i.e., I4 in Table 1) to the TN uplink transmission of the TN terminal.

[0106] like Figure 7As shown, the spectrum F1 in the target spectrum is used for TN uplink transmission and NTN downlink transmission, and the spectrum F2 in the target spectrum is used for TN downlink transmission and NTN uplink transmission. Figure 7 Including (c) and (d). Wherein, (c) and (d) both include satellites, NTN terminals (or UEs), TN terminals (or UEs), and base stations. In (c), the satellite and the NTN terminal can implement NTN downlink transmission, and the base station and the TN terminal can implement TN uplink transmission. The TN uplink transmission of the base station can cause interference of type I5 (i.e., I5 in Table 1) to the NTN downlink transmission of the NTN terminal. The NTN downlink transmission of the satellite can cause interference of type I6 (i.e., I6 in Table 1) to the TN uplink transmission of the TN terminal. In (d), the satellite and the NTN terminal can implement NTN uplink transmission, and the base station and the TN terminal can implement TN downlink transmission. The TN downlink transmission of the base station can cause interference of type I7 (i.e., I7 in Table 1) to the NTN uplink transmission of the NTN terminal. The NTN uplink transmission of the satellite can cause interference of type I8 (i.e., I8 in Table 1) to the TN downlink transmission of the TN terminal.

[0107] To solve the above-mentioned interference and other problems, the target spectrum can be divided into multiple frequency bands, so that NTN (uplink or downlink) and TN (uplink or downlink) can use different frequency bands for transmission, thereby reducing the interference caused by NTN and TN using the same spectrum. The target spectrum is divided into two frequency bands: frequency band FB1 and frequency band FB2. NTN and TN are transmitted on FB1 and FB2 respectively.

[0108] In some embodiments, in the above S301, communicating with the network device of the first category of communication and / or the network device of the second category of communication on the target spectrum specifically includes: based on the first signaling, communicating with the network device of the first category of communication and / or the network device of the second category of communication on the target spectrum. Among them, the first signaling is used to indicate the configuration information of each of the multiple frequency bands divided by the target spectrum. In this way, when the terminal performs NTN transmission and TN transmission, it can transmit on multiple frequency bands respectively through the configuration information of each of the multiple frequency bands, thereby reducing interference. Optionally, multiple frequency bands may overlap or not overlap in the frequency domain. When avoiding interference through FDM, it can be determined that multiple frequency bands do not overlap.

[0109] In addition, there is a guard bandwidth between two adjacent frequency bands in the multiple frequency bands. The guard bandwidth can be configured to the terminal through the NTN / TN network (such as a base station or satellite), or a minimum value / default value can be set according to the radio frequency requirements. If the NTN / TN network is not configured, the guard bandwidth is reserved by default according to the set minimum value / default value.

[0110] In one possible implementation, each of the multiple frequency bands includes any of the following: at least one resource element (RE), at least one resource block (RB), at least one resource block set (RBS), at least one resource block group (RB group), at least one sub-channel, at least one sub-band, at least one carrier partial (CS), at least one bandwidth partial (BWP), at least one carrier, at least one channel. For example, the multiple frequency bands may be at the carrier or channel or cell level, or at the carrier set or channel or cell set level. For example, frequency band FB1 of the multiple frequency bands includes one or more carriers or channels, and frequency band FB2 includes one or more carrier channels.

[0111] In addition, multiple frequency bands may belong to one cell, carrier or channel, that is, the division of the above multiple frequency bands may be performed within one cell, carrier or channel. If the frequency domains of the multiple frequency bands are non-overlapping, the frequency domain resources (such as RBS or BWP) contained in one frequency band and the frequency domain resources contained in another frequency band are also non-overlapping.

[0112] In another possible manner, the NTN / TN network may send a frequency band division indication to the terminal to instruct the terminal to divide the target spectrum into multiple frequency bands. The division of the frequency band (i.e., the frequency band division indication) and / or the configuration information of each frequency band (i.e., the first signaling) may be indicated by the NTN / TN network to the terminal. The indication method includes indication through system information (e.g., MIB, SIB1, OSI signaling, MCE CE and / or DCI signaling, etc.). The configuration information of multiple frequency bands includes at least one of the following: the number of frequency bands, the number of frequency bands, the starting frequency of the frequency band, the ending frequency of the frequency band, the width of the frequency band, the number of guard intervals, the number of guard intervals, the starting frequency of the guard interval, the ending frequency of the guard interval, the width of the guard interval, and the subcarrier spacing. Optionally, if the frequency and width of the frequency band are relative quantities such as RB / RE, the configuration information of multiple frequency bands may include the subcarrier spacing.

[0113] It should be noted that the target spectrum can be divided into multiple frequency bands by the terminal, by the NTN satellite, or by the TN base station. For example, the frequency band division indication and / or the first signaling can be indicated by the NTN / TN network to the TN / NTN network.

[0114] Alternatively, the frequency band division indication and / or the first signaling may be indicated to the NTN / TN network by the core network device / network management system (operation administration maintenance, OAM) / spectrum access system, spectrum management system. For example, the core network device / OAM may be a core network device / OAM connected to the NTN network, or a core network device / OAM connected to the TN network, or a common core network device / OAM connected to the NTN network and the TN network.

[0115] Among them, the spectrum access system or spectrum management system is used to manage the sharing of TN and NTN spectrum, such as determining the spectrum sharing method, semi-statically / dynamically allocating spectrum, and performing interference coordination. It can be an independent node or entity, or it can be integrated in the core network equipment / OAM / base station / satellite.

[0116] The above is a description of dividing a target spectrum into multiple frequency bands. The following will describe the use of multiple frequency bands by NTN and TN in various ways.

[0117] Mode 1: NTN equipment (satellite or terminal) uses the first frequency band in the target spectrum to transmit signals, and TN equipment (base station or terminal) uses the second frequency band in the target spectrum for transmission. The multiple frequency bands after the target spectrum is divided include the first frequency band and the second frequency band. This case is a static or semi-static FDM-based spectrum sharing mode.

[0118] The first frequency band and the second frequency band may be configured as follows: the first frequency band and the second frequency band may overlap or may not overlap. In order to avoid mutual interference, it is preferred that they do not overlap. Optionally, a certain protection bandwidth is reserved between the first frequency band and the second frequency band to avoid interference. The first frequency band may include at least one frequency band among the above-mentioned multiple frequency bands. The second frequency band may include at least one frequency band among the above-mentioned multiple frequency bands.

[0119] For example, Figure 8 As shown, the target spectrum shared by NTN and TN is divided into a first frequency band, a second frequency band, and a protection bandwidth. The first frequency band includes at least one of the following: at least one carrier or channel, or at least one resource element in a cell or carrier or channel, at least one resource block, at least one resource block group, at least one sub-channel, at least one sub-band, at least one carrier part, and at least one bandwidth part. The second frequency band includes at least one of the following: at least one carrier or channel, or at least one resource element in a cell or carrier or channel, at least one resource block, at least one resource block group, at least one sub-channel, at least one sub-band, at least one carrier part, and at least one bandwidth part. Among them, the first frequency band is the frequency band of NTN, and the second frequency band is the frequency band of TN.

[0120] The NTN device and the / TN device can determine the first frequency band and the second frequency band in the following ways:

[0121] Method 1-1: The NTN / TN network or a specific system (eg, spectrum access system, spectrum management system, etc.) sends configuration information of the first frequency band and / or the second frequency band to the TN / NTN network.

[0122] Mode 1-2: The core network device / OAM configures the first frequency band and / or the second frequency band, and sends the configuration information to the TN base station or the NTN base station.

[0123] Mode 1-3: The network with shared spectrum determines the configuration information of the first frequency band and / or the second frequency band, and indicates it to the network with shared spectrum. For example, NTN shares the spectrum of TN. Then the configuration of the first frequency band and the second frequency band is determined by the TN network and indicated to the NTN network (optionally, only the configuration information of the first frequency band may be indicated).

[0124] Mode 1-4: The NTN / TN network (eg, TN base station or NTN base station) sends the configuration of the first frequency band and / or the second frequency band to the terminal through system information, RRC signaling, MACCE, and DCI signaling.

[0125] Method 2: The target spectrum includes dedicated frequency bands and / or public frequency bands.

[0126] Among them, the core network equipment / OAM, NTN / TN network, and a specific system (for example, a spectrum access system, a spectrum management system, etc.) divide a dedicated frequency band and / or a public frequency band from the target spectrum, and send the configuration information of the dedicated frequency band and / or the public frequency band to the NTN / / TN network and / or the terminal. Optionally, the dedicated frequency band may include a frequency band dedicated to the NTN and / or a frequency band dedicated to the TN. Alternatively, the dedicated frequency band may be a frequency band dedicated to the network of the shared spectrum or a frequency band dedicated to the network of the shared spectrum.

[0127] In some embodiments, the multiple frequency bands include at least one of the following: a first frequency band, a second frequency band, and a third frequency band; wherein the first frequency band supports the terminal to communicate with a first type of communication network device; the second frequency band supports the terminal to communicate with a second type of communication network device; the third frequency band supports the terminal to communicate with both the first type of communication network device and the second type of communication network device.

[0128] The first frequency band is a dedicated frequency band of NTN or TN, the second frequency band is a dedicated frequency band of TN or NTN, and the third frequency band is a common frequency band shared by NTN and TN. Optionally, the resource amounts of the first frequency band and the second frequency band may be the same or different.

[0129] In a possible implementation, the dedicated frequency band may also be a frequency band used by NTN and / TN to transmit preset signals, and the public frequency band is a frequency band used to transmit other signals except the preset signals. For example, if NTN shares the TN spectrum, a dedicated frequency band may be configured / defined for TN to be used for preset signals such as access and synchronization of TN equipment (for example, the initial BWP of a TN cell may be configured on this dedicated frequency band). For example, the dedicated frequency band is used to send preset signals such as synchronization signals, broadcast channels, system messages, control channels and / or reference signals of a certain network.

[0130] In another possible implementation, the dedicated frequency band may be further divided into a first dedicated frequency band and a second dedicated frequency band, the first dedicated frequency band is used for the first network (eg, NTN), and the second dedicated frequency band is used for the second network (eg, TN).

[0131] Dedicated frequency bands can also be defined as priority frequency bands / reserved frequency bands. On this frequency band, a certain network has priority to use it, and it can only be used by another network when the network is not using it or is not interfered with. Public frequency bands are frequency bands shared by NTN / TN networks, and are also frequency bands that can be shared fairly by the two networks.

[0132] For example, Fig. 9 A schematic diagram of a dedicated frequency band and a public frequency band is shown. Figure 8 As shown, the target spectrum is divided into NTN dedicated frequency band / reserved frequency band, TN dedicated frequency band / reserved frequency band, and public frequency band.

[0133] Method 3: The base station or satellite uses the target spectrum based on time division multiplexing.

[0134] Among them, the third information can be sent to the TN base station by any one of the core network equipment / OAM, NTN satellite, and specific systems (for example, spectrum access system, spectrum management system, etc.), thereby instructing the TN base station to use the target spectrum in time division through the third signaling; or, the third information can be sent to the NTN satellite by any one of the core network equipment / OAM, TN base station, and specific systems (for example, spectrum access system, spectrum management system, etc.), thereby instructing the NTN satellite to use the target spectrum in time division through the third signaling.

[0135] In some embodiments, communicating with the first type of communication network device and / or the second type of communication network device on the target spectrum specifically includes:

[0136] Based on the third signaling, communication is performed with the network device for the first type of communication and / or the network device for the second type of communication on the target spectrum, and the third signaling is used to indicate configuration information of time-division multiplexing the target spectrum for the first type of communication and the second type of communication.

[0137] In a possible implementation, the base station (or satellite) of the network with the shared spectrum indicates the satellite (or base station) of the network sharing the spectrum through the air interface, and the information of time-division use of the target spectrum. For example, if NTN shares the spectrum of TN, then the TN network indicates the information of time-division use of the shared spectrum by the NTN network.

[0138] Alternatively, the base station (or satellite) of the network sharing the spectrum indicates to the satellite (or base station) of the network sharing the spectrum through the air interface the information of time-division use of the shared spectrum. For example, if NTN shares the spectrum of TN, then the NTN network indicates to the TN network the information of time-division use of the shared spectrum.

[0139] Alternatively, the base station (or satellite) of the interfered network indicates to the satellite (or base station) of the interfering network through the air interface that the shared spectrum is used in time division. For example, if NTN interferes with TN equipment communication, the TN network indicates to the NTN network that the shared spectrum is used in time division.

[0140] Alternatively, the base station (or satellite) of the interfering network instructs the satellite (or base station) of the interfered network to use the shared spectrum in time division through the air interface. For example, if NTN interferes with TN equipment communication, the NTN network instructs the TN network to use the shared spectrum in time division.

[0141] It can be understood that the above-mentioned interfered network and / or interference-causing network can be determined through measurements of network equipment (base stations, satellites).

[0142] In another embodiment, the third signaling includes at least one of the following: pattern, offset, duration, and cycle. The pattern, offset, duration, and cycle of the target spectrum used by the NTN network and / or the TN network in time division. The pattern includes at least one NTN usage duration and / or one TN usage duration. Further, at least one pattern may be included in a cycle. In addition, the pattern may be a time division multiplexing pattern of two networks within at least one time slot, at least one subframe, at least one frame, or other time units (such as milliseconds, seconds, minutes, etc.). Considering the long delay of NTN, the time division multiplexing pattern may be designed with the granularity of one or more time slots / subframes / frames. Fig.10 A schematic diagram of time-division spectrum usage is shown. Fig.10As shown, in a plurality of time slots / subframes / frames, the first time slot / subframe / frame is an offset. A period includes at least one time slot / subframe / frame. In a period, the first two time slots / subframes / frames may adopt pattern 1 of NTN and TN time division multiplexing target spectrum (NTN-TN sharing TDM pattern 1), and the third and fourth time slots / subframes / frames may adopt pattern 2 of NTN and TN time division multiplexing target spectrum (NTN-TN sharing TDM pattern 2).

[0143] For example, during the day, the wireless traffic in a certain area is relatively heavy, so the TN network can be used as the main coverage. In areas where the TN network cannot cover, NTN is used to share the spectrum of TN for coverage (that is, for this area, the daytime can be regarded as the above-mentioned mode 1, and TN does not share the spectrum with NTN). At night, the wireless traffic in this area is relatively light, and this area and the adjacent areas can be fully covered by NTN sharing the spectrum of TN (that is, at night, it can be regarded as the above-mentioned mode 2, and TN shares its own spectrum with NTN). Then in this area, the order of NTN and TN time division multiplexing target spectrum can be: daytime TN-->nighttime NTN-->daytime TN-->nighttime NTN, such TDM mode for spectrum sharing.

[0144] In addition, two pairs of shared links (for example, NTN DL shares TN DL, NTN UL shares TN UL; or, NTN DL shares TN UL, NTN UL shares TN DL) can use the same time division method to use the configuration of the target spectrum. In this case, only one set of configuration needs to be notified. The two pairs of shared links can also use different time division configurations to use the shared spectrum. In this case, one set of configuration needs to be notified for each of the two pairs of shared links, that is, at least two sets of configurations are required.

[0145] In a possible implementation, when NTN and TN share the target spectrum in a time division multiplexing manner, a certain time interval (guard period, GP) needs to be configured between the NTN usage duration and the TN usage duration in the pattern. As needed, the GP durations of different locations (e.g., between NTN-->TN and between TN-->NTN) can be set to be the same or different. Fig.11 A schematic diagram of a GP is shown. Fig.11 As shown, Fig.11Includes (a), (b) and (c). In (a), there is a GP between NTN transmission and TN transmission. For example, when switching from NTN using the target spectrum to TN using the target spectrum, a GP is required to switch, or, when switching from TN using the target spectrum to NTN using the target spectrum, a GP is also required. The opposite is true. In (b), when NTN's downlink transmission uses the target spectrum and switches to TN downlink transmission using the target spectrum, a GP is required to switch, or, when TN downlink transmission uses the target spectrum and switches to NTN downlink transmission using the target spectrum, a GP is required to switch. In (c), when NTN's uplink transmission uses the target spectrum and switches to TN uplink transmission using the target spectrum, a GP is required to switch, or, when TN uplink transmission uses the target spectrum and switches to NTN uplink transmission using the target spectrum, a GP is required to switch.

[0146] In another possible implementation, when NTN and TN share spectrum, the timing synchronization reference point (reference, RP) of NTN is frame aligned with the base station side timing point of TN (e.g., base station side downlink timing point). That is, in the time division multiplexing pattern of NTN and TN, the start and end time of NTN's time division use of the target spectrum is determined according to the timing of the timing synchronization reference point side. The start and end time of TN's use of the spectrum is determined according to the base station side timing.

[0147] Alternatively, when NTN and TN share spectrum, the time division multiplexing pattern of NTN and TN can also be determined by absolute time. That is, in the time division multiplexing pattern of NTN and TN, the start time and end time of NTN and TN using the target spectrum are configured according to absolute time (i.e., hours, minutes, and seconds).

[0148] It can be understood that GP is used for switching the target spectrum between NTN and TN networks, timing advance, and / or preventing interference caused by overlapping use time of the two networks due to transmission delay. That is, one way is that the configured GP duration must be at least greater than or equal to the sum of one or more of the following: the switching duration between NTN and TN networks, the one-way or round-trip transmission delay (or maximum delay) of NTN / TN networks, the timing advance duration (or maximum delay) of NTN / TN networks, or half of the timing advance duration. The transmission delay of NTN / TN networks refers to the transmission delay between NTN RP and NTN terminals.

[0149] For example, in Fig.11 In (b), the GP between the NTN DL and the TN DL needs to be greater than or equal to the maximum delay between the NTN RP and the NTN terminal. Fig.11In (c), the GP between the TN UL and the NTN UL needs to be greater than or equal to half of the maximum timing advance duration of the NTN network (ie, the maximum delay between the NTN RP and the NTN terminal).

[0150] However, due to the very long transmission delay of the NTN network, for example, the round trip time (RTT) of LEO is 25ms and the round trip delay of GEO is 540ms. If the network configures GP completely according to this delay, the spectrum utilization efficiency will be greatly affected. Therefore, when configuring GP, it is necessary to balance the delay, interference and spectrum efficiency. If the GP is small, in order to solve the time domain overlap and interference problems, there are the following methods:

[0151] Mode 3-1: If GP is less than the transmission delay between NTN RP and NTN terminal (or the maximum transmission delay), then the NTN network does not send or schedule downlink transmission in the last period of NTN usage duration. The last period is equal to the transmission delay between NTN RP and NTN terminal minus GP. If GP is not configured between NTN usage duration and TN usage duration in the pattern, it is assumed that GP = 0.

[0152] Fig.12 A schematic diagram of transmission delay is shown. Fig.12 As shown, the NTN RP is synchronized with the TN base station side. In the TDM pattern, time units n, n+1, and n+2 are the durations used by NTN, time unit n+3 is the GP, and time units n+4, n+5, and n+6 are the durations used by TN. Although the NTN base station (gNB) sends DL according to the NTN duration allocated by the above TDM pattern, when the signals of time units n, n+1, and n+2 arrive at the NTN UE side, the time on the RP side is n+3, n+4, and n+5. Therefore, the time when the signals of time units n+1 and n+2 arrive at the NTN UE side is n+4 and n+5 on the RP side (i.e., overlapping with time units n+4 and n+5 on the RP side). And because time units n+4 and n+5 on the RP side are the durations used by TN, in time units n+4 and n+5 on the RP side, there are both NTN downlink signals and TN signals, which may cause interference to TN transmission (i.e., time units n+4 and n+5 are interference areas).

[0153] In this case, on the NTN gNB side, the gNB needs to calculate the last part of the duration (t s,ue +t common -GP) does not send or schedule downlink. s,ue is the time delay between the satellite and the NTN terminal (one-way), t common is the transmission delay between RP and satellite (one-way).s,ue +t common In fact, it is equal to half of the UE timing advance duration, which is also the one-way duration of the corresponding RTT. mac is the transmission delay between the NTN base station and the RP.

[0154] Mode 3-2: If the GP is less than the transmission delay (or maximum transmission delay) between the TN base station and the TN terminal, the TN network does not send or schedule downlink transmission in the last period of the TN usage duration. The last period is equal to the transmission delay between the TN base station and the TN terminal minus the GP. If no GP is configured between the TN usage duration and the NTN usage duration in the pattern, it is assumed that GP = 0.

[0155] Mode 3-3: If the GP is less than the transmission delay (or maximum transmission delay) between the NTN RP and the NTN terminal or half of the timing advance duration (or maximum timing advance duration) of the NTN terminal, the NTN terminal does not send uplink in the first period of the NTN usage duration. The first period is equal to the transmission delay (or maximum transmission delay) between the NTN RP and the NTN terminal or half of the timing advance duration (or maximum timing advance duration) of the NTN terminal minus the GP. If the GP is not configured between the TN usage duration and the NTN usage duration in the pattern, it is assumed that GP = 0.

[0156] Mode 3-4: If the GP is less than the transmission delay (or maximum transmission delay) between the TN base station and the TN terminal or half of the TN terminal timing advance duration (or maximum timing advance duration), the TN terminal does not send uplink in the first period of the TN usage duration. The first period is equal to the transmission delay (or maximum transmission delay) between the TN base station and the TN terminal or half of the TN terminal timing advance duration (or maximum timing advance duration) minus the GP. If the GP is not configured between the NTN usage duration and the TN usage duration in the pattern, it is assumed that GP = 0.

[0157] Mode 4: NTN equipment (satellite or terminal) or TN equipment (base station or terminal) performs frequency band switching.

[0158] The frequency band switching includes activation or deactivation operations. It should be understood that mode 4 can also be applied to NTN devices and / or TN devices to perform switching of other types of resources, such as beam / footprint / cell switching, switching of the time division multiplexing target spectrum, switching from shared spectrum to unshared spectrum for other networks, and switching from unshared spectrum to shared spectrum for other networks.

[0159] In some embodiments, the embodiments of the present disclosure may further include at least one of the following: performing location-based frequency band switching; performing timing-based frequency band switching; performing trigger event-based frequency band switching; performing second signaling-based frequency band switching; reporting resource usage request. Optionally, frequency band switching includes activating a target frequency band or deactivating a target frequency band, and the target frequency band is at least one of the multiple frequency bands.

[0160] In a possible implementation manner, the second signaling comes from any one of the following: NTN network equipment, TN network equipment, spectrum access system, and spectrum management system.

[0161] NTN cells or TN cells can use all or part of the resources of the target spectrum. However, when there is interference between NTN cells or TN cells (based on measurement results), and / or the base station / terminal understands the satellite position and motion trajectory based on the satellite ephemeris, and / or the base station / terminal knows its own position, a frequency band switching (such as BWP switching or sub-band switching) can be performed to ensure that the NTN cell and the TN cell use different frequency bands to reduce mutual interference. For example, the frequency band after the TN terminal is switched is separated from the frequency band used by the NTN terminal in the frequency domain, and vice versa.

[0162] The following describes the way to perform frequency band switching in various ways:

[0163] Mode 4-1: The NTN device and / or the TN device performs location-based frequency band switching.

[0164] The frequency band switching may include carrier switching, BWP switching, and sub-band switching.

[0165] The position can be determined by at least one of the following: a first reference position, such as the center of the current cell, a second reference position, such as the center of the neighboring cell, and a third reference position, such as the terminal position. It should be understood that the above multiple positions can be determined by satellite ephemeris, global navigation satellite system (GNSS) and measurement of signals. Therefore, it is required that the TN terminal can also obtain the satellite ephemeris of the NTN, and accordingly, the NTN terminal can also obtain the position of the TN base station.

[0166] In a possible implementation, the NTN / TN network may configure whether the terminal supports location-based frequency band switching and / or location information related to frequency band switching. The above configuration may be indicated by system information (such as MIB, SIB1, OSI), RRC signaling, MAC CE and / or DCI signaling.

[0167] When the base station / terminal of the TN / NTN cell determines the satellite position and cell coverage according to the satellite ephemeris, and / or the base station / terminal learns its own position and the other party's position, the base station / terminal can perform location-based frequency band switching.

[0168] Fig.13 FIG. 1 shows a schematic diagram of switching frequency bands based on location. Fig.12 As shown, the NTN cell uses the frequency band FB2, and the UE1 in the center of the TN cell can also use FB2. However, when the TN UE1 moves to the TN cell boundary, it needs to switch to FB1 to avoid interference between the NTN and TN. The UE2 in the center of the TN cell can still use FB2 (or FB1). For the TN UE1, the above operation is equivalent to deactivating FB2 and activating FB1.

[0169] Mode 4-2: The NTN device and / or the TN device performs timing-based frequency band switching.

[0170] NTN cell coverage and existence are strongly correlated with time. When NTN cells exist, TN networks sharing the same spectrum need to consider interference with NTN cells (e.g., sharing spectrum through FDM). When NTN cells do not exist, TN networks do not need to consider interference with NTN cells (e.g., TN networks can use all target spectrum or all multiple frequency bands).

[0171] Therefore, for TN terminals, especially terminals at the edge of TN cells, the time when NTN cells cover them can be determined based on satellite ephemeris. When the arrival of NTN cells is determined based on timing information, frequency band switching based on timing (i.e., at the time when NTN cells arrive) can be performed.

[0172] Likewise, during a period when the TN network has a low load or no load (such as at night or at a specific time), the NTN network device may also switch to a frequency band where the TN network has a low load or no load.

[0173] The NTN / TN network can configure whether the terminal supports timing-based frequency band switching, and / or timing information related to frequency band switching (such as NTN ephemeris, NTN / TN service start time, end time, and / or duration, timer on / off, duration). The above configuration can be indicated by system information (such as MIB, SIB1, OSI), RRC signaling, MAC CE and / or DCI signaling.

[0174] Mode 4-3: The NTN device and / or the TN device performs frequency band switching based on a trigger event.

[0175] The TN terminal or NTN terminal may measure signals of the current cell and / or neighboring cells (eg, RSRP / RSRQ / SINR), and decide whether to perform frequency band switching based on a triggering event according to the measurement results.

[0176] The triggering event may include at least one of the following:

[0177] Event 1: The signal strength of the current cell is higher or lower than the first value (or threshold value). When this event is met, the terminal performs frequency band switching. For example, for a terminal at the edge of a TN cell, when its measurement result of the serving cell signal is lower than a certain threshold (i.e., the first value), it means that the frequency band currently in use receives more interference, and the terminal performs frequency band switching from frequency band FB2 to frequency band FB1.

[0178] Event 2: The signal strength of the current cell is lower than the first value (or threshold value), and / or the signal strength of the neighboring cell is higher than the second value (or threshold value). When this event is met, the terminal performs frequency band switching. For example, for a terminal at the edge of a TN cell, when its measurement result of the current cell signal is lower than the first value and the signal strength of the neighboring cell is higher than the second value, it means that the frequency band currently in use receives more interference, and the terminal performs frequency band switching from frequency band FB2 to frequency band FB1.

[0179] It should be noted that the frequency band after NTN or TN switching should be different from the frequency band of TN or NTN, so as to avoid mutual interference between NTN and TN.

[0180] Mode 4-4: The base station (ie, TN base station or NTN satellite) instructs the terminal (TN terminal or NTN terminal) to perform frequency band switching (or activation / deactivation of frequency band) through the second signaling.

[0181] The NTN network / satellite or the TN network / base station may instruct the terminal to switch the frequency band (or activate / deactivate the frequency band) through RRC signaling, MAC CE and / or DCI signaling.

[0182] For example, the network configures and indicates activated / deactivated frequency band information through RRC signaling;

[0183] For another example, the network may configure the frequency band information through RRC signaling, and then instruct the terminal to switch the frequency band through MAC CE.

[0184] As another example, the network may configure the frequency band information through RRC signaling, and then instruct the terminal to switch the frequency band through DCI signaling.

[0185] For another example, the network may configure frequency band information through RRC signaling, then activate / deactivate multiple frequency bands through MAC CE, and then activate / deactivate one or more of the frequency bands through DCI signaling.

[0186] DCI signaling can be carried by PDCCH associated with a cell, group-common or UE-specific search space set. Since TN and NTN interference often involves not a single terminal but a group of terminals, it is preferred to carry DCI signaling through PDCCH associated with a group-common specific search space set to indicate terminal frequency band switching, such as PDCCH of Type3-PDCCH common search space to indicate switching.

[0187] When activating / deactivating a frequency band by RRC signaling, MAC CE or DCI signaling, one or more frequency bands can be activated / deactivated at a time, either by a bitmap (bit) or by indicating a frequency band number. If a bitmap is used, each bit in the bitmap (except the reserved bit) corresponds to a frequency band. A bit of 0 indicates activation of the frequency band; a bit of 1 indicates deactivation of the frequency band. Or the meaning of the bit is the opposite of the above.

[0188] Mode 4-5: The core network device / OAM / spectrum access system, spectrum management system or TN network device instructs the NTN network device to perform frequency band switching. Or the core network device / OAM / spectrum access system, spectrum management system or NTN network device instructs the TN network device to perform frequency band switching (or activation or deactivation of a frequency band).

[0189] In a possible implementation, the network equipment of the network whose spectrum is shared instructs the network equipment of the network sharing the spectrum to switch the frequency band via the air interface. For example, if NTN shares the spectrum of TN, then the TN network equipment (base station) instructs the NTN network equipment (satellite) to perform frequency band switching.

[0190] Alternatively, the network equipment of the network sharing the spectrum instructs the network equipment of the network sharing the spectrum to perform the frequency band switching via the air interface. For example, if the NTN shares the spectrum of the TN, the NTN network instructs the TN network to perform the frequency band switching.

[0191] Alternatively, the network equipment of the interfered network instructs the network equipment of the interfering network to switch the frequency band through the air interface. For example, if the NTN interferes with the communication of the TN equipment, the TN network instructs the NTN network to perform the frequency band switching.

[0192] Alternatively, the network equipment of the interfering network instructs the network equipment of the interfered network to perform frequency band switching via the air interface. For example, if the NTN interferes with the communication of the TN equipment, the NTN network instructs the TN network to perform frequency band switching.

[0193] The interfered network and / or the interfering network may be acquired through measurement of network equipment.

[0194] In addition to the above-mentioned multiple frequency band switching methods, the terminal can also actively switch frequency bands. When the terminal determines based on measurement that the currently used frequency band is seriously interfered, the terminal can report a resource use request to the NTN network device or the TN network device, thereby requesting to switch to a certain resource (or frequency band).

[0195] In another possible implementation, the uplink and downlink using the target spectrum can switch frequency bands together, in pairs, or individually. For example, in a TDD spectrum or mode, the uplink and downlink can switch frequency bands together, and the network device only needs to notify one set of switching frequency band parameters; in an FDD spectrum or mode, the uplink and downlink can switch frequency bands in pairs, and the network device can also only notify one set of switching frequency band parameters; in an FDD spectrum or mode, the uplink and downlink can also switch frequency bands individually, and the network device only notifies one set of switching frequency band parameters, which is then only used for uplink or downlink frequency band switching. If it is necessary to instruct both the uplink or downlink to switch frequency bands, two sets of switching frequency band parameters need to be notified.

[0196] The wireless network communication method provided by the embodiment of the present disclosure can be applied to Figure 2 A network device 202 of the first type of communication in the communication system is shown. Fig.14 A schematic diagram showing a process of a wireless network communication method Figure 2 ,like Fig.14 As shown, the wireless network communication method includes the following S1401.

[0197] S1401. Communicate with a terminal on a target spectrum.

[0198] The target spectrum is a frequency domain resource used by the first type of communication and the second type of communication.

[0199] Taking the first type of communication network device as an NTN network device or a TN network device as an example, the NTN network device or the TN network device can communicate with the terminal on the target spectrum. Since the target spectrum is a frequency domain resource used by NTN and TN, NTN or TN does not need a separate spectrum resource for transmission, thereby saving spectrum resources and improving the utilization rate of spectrum resources.

[0200] It should be pointed out that various descriptions of NTN and TN performing cell switching, frequency band switching, interference avoidance, etc. can refer to the description of the terminal side above, and the embodiments of the present disclosure will not go into details therein.

[0201] In addition, in order to reduce the transmission interference between NTN and TN, in addition to the various methods on the terminal side, the following methods can also be used to handle it:

[0202] In some embodiments, a network device of a first type of communication sends first information to a network device of a second type of communication, or receives first information from a network device of a second type of communication; wherein the first information includes at least one of the following: resource usage information, resource interference information, resource switching request / command, and measurement results.

[0203] In a possible implementation, the first information can also be sent from a network device (first type of communication or second type of communication) to a target network device, and can also be sent from a target network device to a network device (first type of communication or second type of communication). The target network device includes at least one of the following: a core network device to which a network device of the first type of communication is connected; a core network device to which a network device of the second type of communication is connected; a core network device to which a network device of the first type of communication and a network device of the second type of communication are connected; a spectrum access system; a spectrum management system. It should be understood that the above-mentioned and the following core network devices are all core network devices to which network devices of the first type of communication are connected, and / or, core network devices to which network devices of the second type of communication are connected.

[0204] Method 5: The TN network device sends resource usage information (or network resource usage status) to the core network device / OAM / spectrum access system, spectrum management system or NTN network device; or, the NTN network device sends resource usage information to the core network device / OAM / spectrum access system, spectrum management system or TN network device.

[0205] For example, an NTN base station (or TN base station) sends resource usage information of an NTN cell (or TN cell) to a TN base station (or NTN base station). Optionally, a base station (eg, a TN base station) or a cell (eg, a TN cell) may be a base station set or a cell set.

[0206] In a possible implementation, the resource usage information may be the status of the frequency band used by the current cell (or the previous cell), or the information of the frequency band planned to be used after the first time period, or the information of the frequency band requested to be used after the first time period, or the information indicating the frequency band used by the other network. In this way, the first party actively sends its own resource usage information to the other party in the hope that the other party can consider the resource usage information and thus avoid it to reduce interference. However, whether the other network determines to avoid it depends on the needs of the other network or other solutions (such as the above-mentioned multiple frequency band switching methods). For example, the NTN network device sends the frequency band information currently used or used after the first time period to the TN network device, hoping that the TN network device will not use the frequency band information in the current or after the first time period, thereby reducing interference and improving transmission quality.

[0207] Resource usage information may include at least one of the following: 1) time domain resources, such as TDD configuration information, occupied time domain resources, cyclic prefix type, period / offset / duration of resource usage, etc.; 2) frequency domain resources, such as subcarrier spacing, the above-mentioned frequency band, carrier, channel, resource block set, resource block group, subchannel, subband, carrier part, bandwidth part. 3) spatial domain resources, such as beam / footprint / cell, codeword, layer, port, downtilt angle, elevation angle, etc. 4) code domain resources, such as sequence, codeword. 5) energy domain, such as the power of the channel or signal, power boost / backoff value, etc.

[0208] Fig.15 FIG. 1 shows a schematic diagram of transmitting resource usage information. Fig.14 As shown, the NTN satellite can send resource usage information to the TN base station, and the resource usage information includes resource information currently or in future use.

[0209] Solution 6: The TN network device sends resource interference information, measurement results, and / or resource switching commands (or resource switching requests) to the core network device / OAM / spectrum access system, spectrum management system, or NTN network device; or, the NTN network device sends resource interference information, measurement results, and / or resource switching commands (or resource switching requests) to the core network device / OAM / spectrum access system, spectrum management system, or TN network device. Optionally, the resource switching command or resource switching request may be a frequency band switching command or frequency band switching request.

[0210] For example, the NTN base station (or TN base station) sends NTN cell (or TN cell) resource interference information and / or measurement results to the TN base station (or NTN base station). The base station (eg, TN base station) or cell (eg, TN cell) may also be a base station set or a cell set.

[0211] It should be noted that in scheme 6, the resources in the resource interference information / resource switching command / resource switching request are resources that are subject to severe interference, such as frequency bands that are subject to severe interference determined based on measurement results. For example, one party sends information such as the frequency domain resources (such as frequency band number), time domain resources (such as the time period where interference exists), and spatial domain resources (such as beam number) that are currently subject to interference to the other party, hoping that the other party can consider the information sent by itself and avoid interference. However, whether the other party avoids interference depends on the other party's implementation, or is determined by other methods (such as the above-mentioned frequency band switching method).

[0212] In a possible implementation, in the NTN network device and the TN network device, the first party may send a measurement result to the second party, so that the second party determines whether the first place is subject to interference based on the measurement result. If it is determined that interference is suffered, the above-mentioned multiple frequency band switching can be performed, thereby avoiding interference. Alternatively, the first party may determine the resource (e.g., frequency band) that is suffering from interference based on the measurement result, and generate resource interference information. Afterwards, the first party may send the resource interference information to the second party. In this way, after receiving the resource interference information, the second party can determine the resource of the first party that is suffering from interference, so that the above-mentioned multiple frequency band switching can be performed, thereby avoiding interference.

[0213] In another possible implementation, the measurement is related to the mode (or sharing mode) of sharing the target spectrum between NTN and TN. 1) If the sharing mode between NTN and TN is normal pairing sharing based on FDD mode, that is, NTN DL shares TN DL spectrum and NTN UL shares TN UL spectrum, then the measurement result includes the measurement of NTN downlink signal by TN terminal, or the measurement of TN downlink signal by NTN terminal, or the measurement of NTN uplink signal by TN base station, or the measurement of TN uplink signal by NTN base station; 2) If the sharing mode between NTN and TN is reverse pairing sharing based on FDD mode, that is, NTN DL shares TN UL spectrum and NTN UL shares TN DL spectrum, then the measurement result includes the measurement of NTN uplink signal by TN terminal, or the measurement of TN uplink signal by NTN terminal, or the measurement of NTN downlink signal by TN base station, or the measurement of TN downlink signal by NTN base station; 3) If the sharing mode between NTN and TN is based on TDD spectrum or involves TDD mode, then one or more of the above eight measurements are possible. 4) If the measurement result is based on non-specific signal / channel measurement, such as received signal strength indication (RSSI), the measurement result does not distinguish which base station or link of the terminal is measured, and the measurement is for all co-channel or adjacent channel interference.

[0214] Mode 7: The terminal sends a resource use request to the network device (NTN network device or TN network device), and / or the network device sends a resource use permission or allocation to the terminal, where the resource use permission or allocation is used to indicate uplink / downlink resources.

[0215] Among them, the resource usage request includes one or more of the following: 1) time domain resource usage request, such as time domain resource usage or switching request, including NTN-TN time division multiplexing configuration, switching of NTN-TN time division multiplexing configuration, etc.; 2) frequency domain resource usage, switching or activation / deactivation request, such as NTN-TN frequency division multiplexing configuration, switching of NTN-TN frequency division multiplexing configuration, frequency band activation / deactivation, frequency band switching; 3) The information in the resource usage request can also include resource information defined in Scheme 5 and Scheme 6, including other time domain resources, other frequency domain resources, code domain resources, spatial domain resources, or energy domain resource usage requests.

[0216] In a possible implementation, the terminal can judge the change in the network topology or interference of the shared spectrum between the NTN network and the TN network based on information such as measurement, ephemeris, and / or GNSS, and decide whether it is necessary to adjust the resources used (for example, frequency band switching), and then send a resource use request to the base station. The base station feeds back a resource use permission (for example, allowing frequency band switching) to the terminal based on the resource use request sent by the terminal. The resource use permission may include one or more of the following: allowed, not allowed, and self-determined. Further, the resource use request may be sent via PUCCH or PUSCH. The resource use permission may be sent via PDCCH or PDSCH. Optionally, the base station may not send a resource use permission, but directly allocate / instruct the terminal to use the resources, for example, instructing the terminal to perform a switch of the time-division multiplexing shared spectrum configuration, or instructing the terminal to perform a frequency band switch. It should be understood that in this case, the resource use permission may be the second signaling in the above manner, or a signaling instructing the terminal to time-division multiplex the target spectrum, etc.

[0217] Method 8. Among the above-mentioned methods, when the network device or terminal performs dynamic switching of shared spectrum (such as switching of frequency bands, switching of time division multiplexing, switching of beams / footprints, switching from shared spectrum to unshared spectrum, switching from unshared spectrum to shared spectrum, etc.), in order to clarify the switching time, the network device can configure / instruct the terminal to execute the switching (i.e., the switching timing parameters).

[0218] In a possible implementation, the network device may send a switching timing parameter to the terminal, wherein the switching timing parameter includes at least one of the following: a start time point of switching execution, an end time point of switching execution, a duration period of switching execution, and an offset of the start time point / end time point relative to a current time point (e.g., a time when a switching command or a switching configuration parameter is received).

[0219] Among them, the meaning of the offset relative to the current time is: after the offset, the switching needs to be started or completed. In addition, in order to ensure that the terminal can complete the RF adjustment within the switching time, it can be defined that before completing the switching, the terminal may not send a channel sounding reference signal (SRS) / channel state information (CSI) report / random access channel (RACH) / physical uplink shared channel (PUSCH) / physical uplink control channel (PUCCH, or not detect the physical downlink control channel (PDCCH). The timing before the switching can be determined according to the RF timing parameter requirements or according to the timing parameters configured by the base station.

[0220] Method 9: The terminal has the capability to support shared spectrum.

[0221] Taking into account the factors of implementation complexity and cost, for NTN and TN sharing the target spectrum, different terminals may have different sharing capabilities.

[0222] 9-1. The terminal supports / does not support the ability to share spectrum between NTN and TN.

[0223] 9-1-1. The terminal supports / does not support the ability to share uplink NTN and TN spectrum

[0224] The terminal supports / does not support the ability of NTN uplink to share TN spectrum. The terminal supports / does not support the ability of NTN uplink to share TN uplink spectrum. The terminal supports / does not support the ability of NTN uplink to share TN downlink spectrum.

[0225] The terminal supports / does not support the ability of TN uplink to share NTN spectrum. The terminal supports / does not support the ability of TN uplink to share NTN spectrum. The terminal supports / does not support the ability of TN uplink to share NTN spectrum.

[0226] 9-1-2. The terminal supports / does not support the ability to share downlink NTN and TN spectrum

[0227] The terminal supports / does not support the ability of NTN downlink to share TN spectrum. The terminal supports / does not support the ability of NTN downlink to share TN uplink spectrum. The terminal supports / does not support the ability of NTN downlink to share TN downlink spectrum.

[0228] The terminal supports / does not support the ability of TN downlink to share NTN spectrum. The terminal supports / does not support the ability of TN downlink to share NTN uplink spectrum. The terminal supports / does not support the ability of TN downlink to share NTN downlink spectrum.

[0229] When communicating with the NTN network device and / or the TN network device, the terminal may report to the NTN network device and / or the TN network device the terminal capability including whether it supports the shared spectrum. The terminal capability is at least one of the above-mentioned multiple capabilities. In the embodiment of the present disclosure, the terminal capability reporting of mode 9 may also be applied to the terminal side in the embodiment of the present disclosure.

[0230] If the terminal supports NTN and TN shared spectrum, the network device can configure the spectrum required to be shared for the uplink and / or downlink of the terminal. Otherwise, the network device will not configure the spectrum required to be shared for the uplink and / or downlink of the terminal.

[0231] The wireless network communication method provided by the embodiment of the present disclosure can be applied to Figure 2 The communication system shown is a network device 203 for second type of communication. Fig.16 A schematic diagram showing a process of a wireless network communication method Figure 3 ,like Fig.16 As shown, the wireless network communication method includes the following S1601.

[0232] S1601. Communicate with a terminal on a target spectrum.

[0233] The target spectrum is a frequency domain resource used by the first type of communication and the second type of communication.

[0234] Taking the second type of communication network device as NTN network device or TN network device as an example, the NTN network device or TN network device can communicate with the terminal on the target spectrum. Since the target spectrum is a frequency domain resource used by NTN and TN, NTN or TN does not need a separate spectrum resource for transmission, thereby saving spectrum resources and improving the utilization rate of spectrum resources.

[0235] It should be pointed out that, since one of the first type of communication and the second type of communication can be NTN and the other can be TN, the various descriptions of cell switching, frequency band switching, interference avoidance, etc. performed by NTN and TN can refer to the description on the terminal side above, and the configuration of the first information between the NTN network device and the TN network device, the configuration of the switching timing parameters, etc. can all refer to the network device side of the first type of communication above, and the embodiments of the present disclosure will not go into details about this.

[0236] Combining the above methods, Fig.17 A schematic diagram of a method for sharing NTN and TN resources is shown. Fig.17 As shown, resource sharing between NTN and TN includes cell selection between NTN and TN, and cooperation and resource sharing between NTN and TN. Cell selection between NTN and TN includes the above-mentioned schemes 2-1 to 2-7. Cooperation and resource sharing between NTN and TN includes methods 1 to 9.

[0237] It is understandable that, in order to implement the above functions, the communication device includes hardware structures and / or software modules corresponding to the execution of each function. Those skilled in the art should easily realize that, in combination with the algorithm steps of each example described in the embodiments of the present disclosure, the present disclosure can be implemented in the form of hardware or a combination of hardware and computer software. Whether a function is executed in the form of hardware or computer software driving hardware depends on the specific application and design constraints of the technical solution. Professional and technical personnel can use different methods to implement the described functions for each specific application, but such implementation should not be considered to be beyond the scope of the present disclosure.

[0238] The embodiments of the present disclosure may divide the functional modules of the communication device according to the above method embodiments. For example, each functional module may be divided corresponding to each function, or two or more functions may be integrated into one functional module. The above integrated modules may be implemented in the form of hardware or software. It should be noted that the division of modules in the embodiments of the present disclosure is schematic and is only a logical function division. There may be other division methods in actual implementation. The following is an example of dividing each functional module corresponding to each function.

Figure 1 , the communication device can execute the communication method provided by the above method embodiment. Fig.18 As shown, the communication device includes: a communication unit 1801.

[0250] In a possible implementation manner, the second signaling comes from any one of the following: a network device for the first type of communication, a network device for the second type of communication, a spectrum access system, and a spectrum management system.

[0254] The processing unit 1802 is configured to determine a target cell that meets a cell switching condition from a plurality of candidate cells, where the plurality of candidate cells include cells for first-category communications and cells for second-category communications.

[0255] The processing unit 1802 is configured to switch from a source cell to a target cell.

[0256] In a possible implementation manner, the processing unit 1802 is specifically configured to: determine a target cell from a plurality of candidate cells based on respective priorities of the plurality of candidate cells.

[0257] In one possible implementation, the priority satisfies any one of the following relationships: the priority of a cell switched to the first type of communication is equal to the priority of a cell switched to the second type of communication; the priority of a cell switched to the first type of communication is higher than the priority of a cell switched to the second type of communication; the priority of a cell switched to the first type of communication is lower than the priority of a cell switched to the second type of communication.

[0258] In a possible implementation manner, the relationship between the priority of the cell for the first type of communication and the priority of the cell for the second type of communication is predefined, or determined by the network side, or determined by the terminal side.

[0259] In a possible implementation manner, the relationship between the priority of the cell for the first type of communication and the priority of the cell for the second type of communication is determined according to the source of the target spectrum.

[0260] In one possible implementation, when the target spectrum originates from the first type of communication, the priority of the cell switched to the first type of communication is higher than the priority of the cell switched to the second type of communication; or, when the target spectrum originates from the second type of communication, the priority of the cell switched to the first type of communication is lower than the priority of the cell switched to the second type of communication.

[0261] In a possible implementation, the communication unit 1801 is further configured to receive configuration parameters of a cell switching condition in a conditional switching command, where the configuration parameters include at least one of the following: a threshold value and an offset value.

[0262] In a possible implementation manner, the threshold value includes a first threshold value corresponding to a cell of the first type of communication, and a second threshold value corresponding to a cell of the second type of communication.

[0263] In a possible implementation manner, the offset value includes a first offset value corresponding to a cell of the first type of communication, and a second offset value corresponding to a cell of the second type of communication.
