Description

Communication methods, devices and storage media

[0001] This disclosure claims priority to Chinese Patent Application No. 2024104780326, filed on April 19, 2024, entitled "Communication Method, Apparatus and Storage Medium", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This disclosure relates to the field of communication technology, and in particular to a communication method, apparatus and storage medium. Background Technology

[0003] Faced with constantly innovating wireless communication technologies and continuously growing business demands, the traditional static spectrum management method allocates spectrum bandwidth to specific wireless communication systems in certain areas, leading to an increasingly severe contradiction between spectrum supply and demand. Unlike the traditional static exclusive allocation spectrum management model, spectrum sharing allows for the sharing of the same idle or underutilized frequency bands for data transmission without affecting user service quality, thereby enabling the coexistence of users with different permissions or multiple services.

[0004] In a converged satellite-terrestrial network, a multi-layered, three-dimensional network is formed between satellites and ground base stations. As user service demands increase, spectrum resources become increasingly scarce, and the traditional method of dedicated frequency allocation significantly reduces spectrum utilization efficiency. Spectrum sharing can shift the relationship between satellite and terrestrial communications from frequency competition to frequency cooperation, greatly improving spectrum utilization.

[0005] Traditional frequency reuse technologies, such as time division, space division, and code division, require extensive coordination between non-terrestrial and terrestrial networks. However, satellites in non-terrestrial networks are mobile, and the topology of these networks is constantly changing, making coordination between non-terrestrial and terrestrial networks relatively complex.

[0113] In this embodiment of the invention, the term "and / or" describes the relationship between associated objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. The character " / " generally indicates that the preceding and following associated objects have an "or" relationship.

[0114] In this disclosure, the term "multiple" refers to two or more, and other quantifiers are similar.

[0115] The technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments of this disclosure, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this disclosure.

[0116] In non-terrestrial networks (NTNs), such as satellite networks and airborne networks, there are two operating modes: transparent forwarding mode and regenerative communication mode.

[0117] In transparent relay mode, the satellite simply relays signals transparently without performing any processing; the terminal device and the gateway station communicate. That is, the satellite only performs frequency conversion and wireless signal amplification on the uplink or downlink signals, functioning similarly to a radio frequency repeater. Figure 1 illustrates a satellite communication scenario based on transparent relay. As shown in Figure 1, the terminal device connects to the gateway station via the satellite, thereby accessing the data network. The connection between the terminal device and the satellite is called the user link, and the connection between the satellite and the gateway station is called the feeder / feederline link.

[0118] In regenerative communication mode, the satellite can detect and process the received signal information, performing the functions of a base station. The satellite connects the terminal and the gateway station. That is, the satellite can perform functions such as frequency conversion, wireless signal amplification, encoding / modulation, and decoding / decoding of uplink or downlink signals. In other words, the satellite can possess all or some of the functions of a base station (such as a gNB), and can regenerate signals.

[0119] There are two cell types in non-terrestrial networks: Earth-Fixed cells and Earth-moving cells.

[0120] A fixed-area ground cell is one in which the ground coverage area of ​​the satellite's serving cell does not change as the satellite moves; it uses a "staring" mode. The satellite moves, but the ground coverage area of ​​its serving cell remains unchanged, as if the satellite is "staring" at a specific area of ​​the ground. Figure 2a shows an exemplary schematic diagram of a fixed-area ground cell. As shown in Figure 2a, the satellite moves from time T1 to time T2, and the satellite's coverage area on the ground is always A, both before and after time T1. A quasi-Earth Fixed cell, also known as a similar fixed-area ground cell, refers to a satellite "staring" at the ground for a certain period of time. For example, the satellite's coverage area on the ground is A between time T1 and T2, but it is not A before time T1 or after time T2. In this scenario, as the satellite moves, the angle between the satellite antenna and the ground changes, thus ensuring that the area covered by the satellite antenna remains constant.

[0121] A ground-based mobile cell refers to a cell whose ground coverage area changes as the satellite moves within a certain time period. Figure 2b shows an exemplary schematic diagram of a ground-based mobile cell. As shown in Figure 2b, the satellite's coverage area is A at time T1 and B at time T2. In this scenario, the angle between the satellite antenna and the ground remains almost constant during the satellite's movement.

[0122] In scenarios involving space-ground integration or air-space-ground integration, the goal is to achieve harmonious coexistence between non-terrestrial networks and terrestrial networks (TN). This includes the coordinated use of spectrum resources to improve their utilization rate. Figure 3 illustrates a schematic diagram of the network architecture for space-ground integration.

[0123] As shown in Figure 3, non-terrestrial networks include, but are not limited to, satellite networks belonging to space-based networks and near-space networks. Space-based satellite networks include geostationary Earth Orbit (GEO), high Earth Orbit (HEO) or highly elliptical orbit (HEO), medium Earth Orbit (MEO), and low Earth Orbit (LEO) satellites. Near-space networks include, but are not limited to, networks composed of or provided by drones, airships, aircraft, and other flying devices. For ease of description, the following description will primarily use satellite networks as an example. However, unless otherwise specified, the description also applies to other non-terrestrial networks.

[0124] As shown in Figure 3, the terrestrial network (TN) includes, but is not limited to, terrestrial mobile communication networks, telemetry, tracking, and command (TT&C) stations, and gateway stations. Other components of the satellite-terrestrial converged network architecture shown in Figure 3 can be referenced from relevant technologies and will not be elaborated upon here.

[0125] 3GPP defines two frequency ranges: FR1 (Frequency Range 1) and FR2 (Frequency Range 2). FR1 is a low-frequency band, and FR2 is a high-frequency band. FR2 is further divided into FR2-1 and FR2-2. Table 1 shows the frequency ranges of FR1 and FR2.

[0126] Table 1

[0127] Within the FR1 range, the frequency resources of the 5G terrestrial network allocated by 3GPP are shown in Table 2. It should be noted that in Table 2, NR operating band represents the effective NR frequency band, Uplink (UL) operating band represents the effective uplink frequency band, BS receive represents network (base station) reception, UE transmit represents user equipment transmission, and FR1 represents network (base station) transmission, UE receive represents user equipment reception, and FR1 represents network (base station) reception, UE transmit represents user equipment reception, and FR1 represents network (base station) transmission, UE transmit represents user equipment reception, and FR1 represents network (base station) reception ... UL,low Indicates the lowest uplink frequency, F UL,high The uplink (DL) operating band indicates the highest uplink frequency, and the downlink (DL) operating band indicates the effective downlink frequency band. DL,low Indicates the lowest downlink frequency, F DL,high This indicates the highest downlink frequency, and "Duplex mode" indicates the duplex mode. As shown in Table 2, the effective frequency bands for NR include bands numbered n1 to n105; the duplex modes include Frequency Division Duplexing (FDD), Time Division Duplexing (TDD), Supplementary Upload (SUL), and Supplementary Download (SDL).

[0128] Table 2

[0129] Within the FR1 range, the frequency resources allocated to 5G non-terrestrial networks (NTN) are shown in Table 3. In Table 3, "Satellite operating band" represents the effective frequency band for satellites, "SAN receive" represents satellite access node reception, and "SAN transmit" represents satellite access node transmission.

[0130] Table 3

[0131] Within the FR2 range, it is not defined how to specifically allocate frequency bands to terrestrial or non-terrestrial networks. The frequency band allocation for FR2 is shown in Table 4.

[0132] Table 4

[0133] Faced with constantly innovating wireless communication technologies and continuously growing business demands, the traditional static spectrum management approach allocates spectrum bandwidth to specific wireless communication systems in certain areas, leading to an increasingly severe contradiction between spectrum supply and demand. On the one hand, most of the low-frequency bands below 6 GHz used for wireless communication have been almost completely allocated through dedicated licensing, making spectrum resources increasingly scarce. The industry can only seek to promote the development and research of new frequency bands, such as millimeter waves and terahertz. On the other hand, the utilization efficiency of most allocated frequency bands is very low, and their usage is highly unbalanced in terms of frequency, time, and space. Therefore, in addition to actively developing unused frequency bands, the more important and fundamental issue is how to improve the utilization efficiency of limited spectrum resources.

[0134] Unlike the traditional static, dedicated spectrum management model, spectrum sharing allows users to share the same idle or underutilized frequency bands for data transmission without affecting service quality, thus enabling the coexistence of users with different permissions and various services. Therefore, spectrum sharing plays a crucial role in 5G and its enhanced systems. In recent years, the industry has been researching various advanced technologies, such as cognitive radio, D2D (Device to Device), unlicensed spectrum, non-orthogonal multiple access, in-band full-duplex, and flexible multi-band aggregation, in order to achieve multi-dimensional, multi-domain (time domain, spatial domain, code domain, etc.) multiplexing and sharing of spectrum resources.

[0135] In space-ground converged networks, a multi-layered, three-dimensional network is formed between satellites and ground base stations. With the increasing demand for user services, spectrum resources are becoming increasingly scarce, and traditional dedicated frequency allocation methods have significantly reduced spectrum utilization efficiency. To improve frequency resource utilization efficiency, it is necessary to study the signal transmission characteristics of multi-layered space networks and explore soft frequency reuse methods for space-ground communication by utilizing differences in beamforming and coverage. Through interference prediction and resource coordination, further research should be conducted on dynamic frequency sharing and reuse technologies and methods, while simultaneously improving cell edge transmission efficiency and reducing cell edge interference.

[0136] Spectrum sharing enables satellite and terrestrial communications to shift from a frequency competition relationship to a frequency cooperation relationship, greatly improving spectrum utilization. For the mid-to-high frequency bands, which are of great interest to both satellite and terrestrial communications, the spatial distribution differences between space-based and ground-based wireless transmission links allow terminals to better distinguish between satellite and terrestrial communication signals based on signal direction and other characteristics, achieving spatial multiplexing and interference avoidance.

[0137] Existing frequency reuse technologies, such as time division, space division, and code division, require extensive coordination between non-terrestrial and terrestrial networks. However, satellites in non-terrestrial networks are mobile, and the topology of non-terrestrial networks is constantly changing, making coordination between non-terrestrial and terrestrial networks relatively complicated.

[0138] This disclosure provides a communication method and apparatus that achieves resource reuse by differentiating communication methods, thereby significantly improving resource utilization. For non-terrestrial and terrestrial networks in a space-ground integrated network, based on the communication method and apparatus provided in this disclosure, different communication methods can be used for resource reuse, greatly improving resource utilization.

[0139] The method and apparatus are based on the same concept of the application. Since the methods and apparatus solve problems in similar ways, the implementation of the apparatus and methods can refer to each other, and the repeated parts will not be described again.

[0140] The technical solutions provided in this disclosure can be applied to a variety of systems. For example, applicable systems may include Long Term Evolution (LTE) systems, LTE Frequency Division Duplex (FDD) systems, LTE Time Division Duplex (TDD) systems, Long Term Evolution Advanced (LTE-A) systems, Universal Mobile Telecommunications System (UMTS), Worldwide Interoperability for Microwave Access (WiMAX) systems, 5G New Radio (NR) systems, and their evolved communication systems. These systems may include terminal equipment and network equipment. The systems may also include a core network component, such as Evolved Packet System (EPS) or 5G systems (5GS).

[0141] The terminal devices involved in the embodiments of this disclosure can be devices that provide voice and / or data connectivity to users, handheld devices with wireless connectivity, or other processing devices connected to a wireless modem. The names of the terminal devices may differ in different systems; for example, in a 5G system, a terminal device can be called User Equipment (UE). Wireless terminal devices can be USB storage devices, other personal computer memory devices, and dongles. They can also communicate with one or more core networks (CNs) via a Radio Access Network (RAN). Wireless terminal devices can be mobile terminal devices, such as mobile phones (or "cellular" phones) and computers with mobile terminal devices. For example, they can be portable, pocket-sized, handheld, computer-embedded, or vehicle-mounted mobile devices that exchange voice and / or data with the radio access network. Examples of such devices include Personal Communication Service (PCS) telephones, cordless phones, Session Initiated Protocol (SIP) phones, Wireless Local Loop (WLL) stations, Personal Digital Assistants (PDAs), personal computers, tablets, and Machine-type Communication (MTC) terminal devices. Wireless terminal devices can also be referred to as systems, subscriber units, subscriber stations, mobile stations, mobile devices, remote stations, access points, remote terminals, access terminals, user terminals, user agents, user devices, and wireless access devices and routers / modems that meet the limitations of this definition, but are not limited to these in the embodiments of this disclosure.

[0142] The network device involved in this disclosure can be a base station, which may include multiple cells providing services to terminals. Depending on the specific application, the base station may also be called an access point, or a device in the access network that communicates with wireless terminal devices through one or more sectors on the air interface, or other names. The network device can be used to exchange received air frames with Internet Protocol (IP) packets, acting as a router between the wireless terminal device and the rest of the access network, where the rest of the access network may include an Internet Protocol (IP) communication network. The network device can also coordinate the attribute management of the air interface. For example, the network device involved in this disclosure can be an evolved Node B (eNB or e-NodeB) in a long term evolution (LTE) system, a 5G base station (gNB) in a next generation system, a Home evolved Node B (HeNB), a relay node, a femto, a pico, a network testing device, or a network device in 6G, 7G, and XG systems, etc., and is not limited in this disclosure. In some network architectures, network devices may include centralized unit (CU) nodes and distributed unit (DU) nodes, which may also be geographically separated.

[0143] In this embodiment of the disclosure, the terminal device sends relevant information or similar descriptions to the network device, which only indicates that the terminal device sends relevant information via wireless signals. The destination recipient is the network device, and the network device can obtain the relevant information by receiving the wireless signals.

[0144] In an exemplary embodiment, as shown in FIG4, a communication method is provided, which can be applied to terminal devices in a space-ground converged network. As shown in FIG4, the method may include:

[0145] Step S401: Receive the first resource configuration information.

[0146] The first resource configuration information can be used to indicate a first resource. The first resource can represent a resource that can be reused by different communication methods. In this embodiment, the first resource can be reused by a first communication method and a second communication method, and the first and second communication methods are different.

[0147] In this embodiment, two different communication methods are provided: a first communication method and a second communication method. These two communication methods can reuse a first resource. This reuse can refer to simultaneous reuse of the first resource or staggered reuse of the first resource at different times. In other words, when using the first communication method on the first resource, it satisfies its own communication needs without interfering with communication using the second communication method simultaneously on the first resource. Therefore, "reuse" can mean simultaneous use. For example, "the first communication method and the second communication method can reuse the first resource" can be understood as the first resource being used by both the first and second communication methods simultaneously. However, it should be noted that using the first communication method on the first resource does not necessarily require simultaneous communication using the second communication method on the first resource. That is, "when using the first communication method on the first resource, it satisfies its own communication needs without interfering with communication using the second communication method simultaneously on the first resource" is a requirement or objective. However, on the first resource, there can be only communication using the first communication method, only communication using the second communication method, or simultaneous communication using both methods.

[0148] In one possible implementation, the bandwidth of the first communication method is a first bandwidth, and the power spectral density (PSD) of the first communication method is a first power spectral density; the bandwidth of the second communication method is a second bandwidth, and the power spectral density of the second communication method is a second power spectral density; the first bandwidth is greater than the second bandwidth, and / or the first power spectral density is less than the second power spectral density. Alternatively, the bandwidth of the first communication method is not less than the first bandwidth, and the power spectral density (PSD) of the first communication method is not greater than the first power spectral density; the bandwidth of the second communication method is not greater than the second bandwidth, and the power spectral density of the second communication method is not less than the second power spectral density; the first bandwidth is greater than the second bandwidth, and / or the first power spectral density is less than the second power spectral density.

[0149] When the first bandwidth is greater than the second bandwidth, or when the first power spectral density is less than the second power spectral density, or when the first bandwidth is greater than the second bandwidth and the first power spectral density is less than the second power spectral density, the first communication method and the second communication method are used simultaneously on the first resource. This can satisfy the communication requirements of the first communication method and the second communication method themselves, and will not cause interference to each other, thus ensuring communication quality and improving frequency utilization.

[0150] In one example, the first communication method can be a high-bandwidth, low-power spectral density communication method. The second communication method can be a narrowband / wideband, high-power spectral density communication method. The first and second communication methods are described below.

[0151] The first communication method is characterized by a large bandwidth and a low power spectral density; that is, the initial bandwidth is large, and the initial power spectral density is low. Under this communication mechanism, possible modulation methods include pulse modulation, spread spectrum (e.g., frequency-hopping spread spectrum, time-hopping spread spectrum, direct sequence spread spectrum, and combined spread spectrum), or multi-band orthogonal frequency division multiplexing (OFDM). The main purpose of modulation is to expand the signal transmission bandwidth. Simultaneously, a lower power spectral density is used to transmit the signal over the expanded large bandwidth.

[0152] For example, large bandwidth can be divided into ultra-wideband and near-ultra-wideband. Ultra-wideband can have an absolute bandwidth of over 500MHz (-10dB) or a relative bandwidth of over 20%. Near-ultra-wideband can have an absolute bandwidth of less than 500MHz (e.g., 400MHz or 300MHz) or a relative bandwidth of less than 20%, but not significantly less than 20% (e.g., 15% or 18%). It should be noted that large bandwidth can also be flexibly defined. For example, if the first bandwidth B1 is much larger than the second bandwidth B2, then the first bandwidth B1 can be called large bandwidth.

[0153] For example, a low power spectral density could be -41.3 dBm. The low power spectral density can also be defined flexibly. For instance, the first power spectral density PSD1 can be much smaller than the second power spectral density PSD2. Alternatively, the first power spectral density PSD1 can be much smaller than the power spectral density threshold PSD-threshold. This power spectral density threshold PSD-threshold can be given by one of the two networks participating in frequency reuse or negotiated by both. Taking the first network as TN and the second network as NTN as an example, if the TN's uplink transmission uses the NTN's uplink frequency, a power spectral density threshold PSD-threshold can be given by NTN or negotiated between NTN and TN, ensuring that PSD1 is smaller than PSD-threshold. This PSD-threshold ensures that when the TN's uplink transmission uses the NTN's uplink frequency, it will not interfere with the NTN's uplink reception.

[0154] The second communication method is characterized by narrowband / wideband and high power spectral density; that is, the second bandwidth is either narrowband or wideband, and the second power spectral density is high. This second communication method can use some narrowband / wideband communication mechanism employed by 3G, 4G, 5G, and future 5G-A, 6G, or XG.

[0155] Figure 5 shows an exemplary schematic diagram of power spectral density. The second communication method uses the bandwidth and transmit power spectral density illustrated in Figure 5 for narrowband or wideband, while the first communication method uses the bandwidth and transmit power spectral density illustrated in Figure 5 for ultra-wideband. It can be seen that the bandwidth illustrated in Figure 5 for ultra-wideband is much larger than that for narrowband and wideband; however, the transmit power spectral density corresponding to ultra-wideband is much smaller than that corresponding to narrowband and wideband.

[0156] In one example, the absolute bandwidth of the first bandwidth is greater than the first bandwidth threshold; the relative bandwidth of the first bandwidth is greater than the second bandwidth threshold; and the difference between the first bandwidth and the second bandwidth is greater than or equal to the bandwidth difference threshold.

[0157] In one example, the first power spectral density is less than the second power spectral density; the difference between the second power spectral density and the first power spectral density is greater than or equal to a power spectral density difference threshold. The power spectral density threshold is determined through negotiation between the first and second networks participating in frequency reuse.

[0158] Additionally, the power spectral density of information transmitted by the terminal device of the first network on the first resource can be determined based on whether the second network device (i.e., the network device of the second network) is within the target range. The second network device and the first network device (i.e., the network device of the first network) communicating with the terminal device of the first network participate in frequency reuse, and the target range is a certain range in the uplink communication direction from the terminal device of the first network to the first network device (see Figures 11 and 12).

[0159] In one possible implementation, the first resource configuration information is sent by the first network. Step S401 may include receiving the first resource configuration information from the first network. The method by which the first network determines the first resource configuration information will be described later and will not be repeated here.

[0160] In one possible implementation, the first resource configuration information is sent by the second network. Step S401 may include receiving the first resource configuration information from the second network. The method by which the second network determines the first resource configuration information will be described later and will not be repeated here.

[0161] Taking the uplink transmission of the TN using the uplink frequency of the NTN as an example, the first resource is a resource on the uplink frequency of the NTN, and this first resource can be used for uplink transmission of the TN. That is, the first resource configuration information configures the resource on the uplink frequency of the NTN, but this resource can also be used for uplink transmission of the TN. Therefore, the terminal device can receive the first resource configuration information from either the TN or the NTN. Similarly, taking the uplink transmission of the NTN using the uplink frequency of the TN as an example, the first resource is a resource on the uplink frequency of the TN, and this first resource can be used for uplink transmission of the NTN. That is, the first resource configuration information configures the resource on the uplink frequency of the TN, but this resource can also be used for uplink transmission of the NTN. Therefore, the terminal device can receive the first resource configuration information from either the NTN or the TN.

[0162] Step S402: Communicate using the first communication method on the first resource.

[0163] The terminal device can send uplink signals or receive downlink signals using the first communication method on the first resource.

[0164] In one example, the bandwidth of the first communication method is the first bandwidth, and the power spectral density of the first communication method is the first power spectral density. Step S402 may include: transmitting an uplink signal on the first resource using the first power spectral density on the first bandwidth, or receiving a downlink signal on the first resource using the first power spectral density on the first bandwidth.

[0165] In one possible implementation, the first resource can be a resource on a first frequency, and the first frequency can be a frequency allocated to the second network.

[0166] In this embodiment of the disclosure, the first network can reuse resources on frequencies allocated to the second network. For example, the first network can represent a non-terrestrial network and the second network can represent a terrestrial network; or, the first network can represent a terrestrial network and the second network can represent a non-terrestrial network. The non-terrestrial network can be a satellite network, a near-space network, a portion of the non-terrestrial mobile communication network in 5G, future 5G-A, 6G, or XG networks, or the space-based network and near-space network shown in Figure 3. The terrestrial network can be a portion of the terrestrial mobile communication network in 3G, 4G, 5G, future 5G-A, 6G, or XG networks, or the ground-based network shown in Figure 3.

[0167] In one example, the first frequency is the uplink frequency allocated to the second network, and the first resource is the resource on the first frequency. The first resource is used by the second network to transmit uplink signals using the second communication method. That is, the terminal device of the second network can use the second communication method to transmit uplink signals to the second network using the first resource. At this time, step S402 may include: transmitting uplink signals to the first network using the first communication method on the first resource.

[0168] Terminal devices in the first network send uplink signals to the first network using a first communication method on the first resource, while terminal devices in the second network send uplink signals to the second network using a second communication method on the first resource. This achieves uplink frequency multiplexing from the first network to the second network. It should be noted that the sending of uplink signals by terminal devices in the first network using the first communication method and by terminal devices in the second network using the second communication method on the first resource can occur simultaneously or at different times; this embodiment does not impose any limitations on this.

[0169] In another example, the first frequency is a downlink frequency allocated to the second network, and the first resource is a resource on the first frequency. The first resource is used by the second network to receive downlink signals using a second communication method. That is, the second network can send downlink signals to terminal devices of the second network using the second communication method on the first resource. In this case, step S402 may include: receiving downlink signals from the first network using the first communication method on the first resource.

[0170] A first network transmits downlink signals to terminal devices of the first network using a first communication method on the first resource, and a second network transmits downlink signals to terminal devices of the second network using a second communication method on the first resource, thereby realizing downlink frequency multiplexing of the first network to the second network. It should be noted that the transmission of downlink signals by the first network using the first communication method on the first resource and the transmission of downlink signals by the second network using the second communication method on the first resource can occur simultaneously or at different times, and this embodiment does not impose any restrictions on this.

[0171] Taking a terrestrial network as the first example and a non-terrestrial network as the second example, Figure 6 illustrates a schematic diagram of a terrestrial network reusing frequencies from a non-terrestrial network. As shown in Figure 6, UE A and UE B are terminal devices, gNB1 and gNB2 are base stations, UE A is the terminal device of the NTN, and UE B is the terminal device of the TN. The uplink frequency of the NTN is denoted as the NTN frequency. UE A uses the second communication method (e.g., non-ultra-wideband) to send uplink signals, while UE B uses the first communication method (e.g., ultra-wideband / quasi-ultra-wideband). Both UE A and UE B use the NTN frequency. The uplink transmission from UE B to gNB2 (TN) uses the NTN uplink frequency, but this does not interfere with the uplink reception of the NTN. Of course, the uplink transmission from UE B to gNB2 (TN) can also use the NTN downlink frequency.

[0172] Taking a non-terrestrial network as an example and a terrestrial network as an example, Figure 7 shows a schematic diagram of a non-terrestrial network reusing terrestrial network frequencies. As shown in Figure 7, UE A and UE B are terminal devices, gNB1 and gNB2 are base stations, UE A is the terminal device of NTN, and UE B is the terminal device of TN. The uplink frequency of TN is denoted as the TN frequency. UE B uses the second communication method (e.g., non-ultra-wideband) to send uplink signals, and UE A uses the first communication method (e.g., ultra-wideband / quasi-ultra-wideband) to send uplink signals. Both UE A and UE B use the TN frequency. The uplink transmission from UE A to gNB1 (NTN) uses the TN uplink frequency, but it will not interfere with the TN uplink reception. Of course, the uplink transmission from UE A to gNB1 (NTN) can also use the TN downlink frequency.

[0173] In one possible implementation, the first resource can be a resource on a second frequency, which can be a frequency allocated to the first network.

[0174] In this embodiment of the disclosure, the uplink and downlink of the terminal devices of the first network reuse resources on the same frequency. Taking a second frequency allocated to the first network and a first resource as an example, the uplink and downlink of the terminal devices of the first network can reuse the first resource. When reusing the first resource, the uplink and downlink of the terminal devices of the first network need to use different communication methods to avoid interference between them. For example, the terminal devices of the first network can use a first communication method to send uplink signals on the first resource and use a second communication method to receive downlink signals on the first resource (the terminal devices of the first network that send uplink signals and receive downlink signals can be the same or different terminal devices); or, the terminal devices of the first network can use a second communication method to send uplink signals on the first resource and use a first communication method to receive downlink signals on the first resource (the terminal devices of the first network that send uplink signals and receive downlink signals can be the same or different terminal devices). In this way, by reusing the first resource for uplink and downlink by the same terminal device or different terminal devices, resources can be effectively saved.

[0175] In a ground-to-satellite converged network, there is an uplink / downlink separation mechanism. For example, in the communication process of the same terminal device, the downlink goes to a non-terrestrial network and the uplink goes to a terrestrial network, or the downlink goes to a terrestrial network and the uplink goes to a non-terrestrial network.

[0176] Figure 8 illustrates uplink / downlink separation in a scenario where the ground station of a non-terrestrial network and the base station of a terrestrial network do not co-locate. As shown in Figure 8, terminal device UE A sends uplink signals (uplink data, signaling, physical layer signals / channels) to base station gNB2 via the TN, thereby accessing the core network and data network. Terminal device UE A receives downlink signals (downlink data, signaling, physical layer signals / channels) from base station gNB1, the gateway station, and satellite reception via the NTN.

[0177] Figure 9 illustrates the uplink / downlink separation in a scenario where a ground station of a non-terrestrial network and a base station of a terrestrial network co-locate. As shown in Figure 9, terminal device UE A sends uplink signals (uplink data, signaling, physical layer signals / channels) to base station gNB via TN, thereby accessing the core network and data network. Terminal device UE A receives downlink signals (downlink data, signaling, physical layer signals / channels) from base station gNB, gateway station, and satellite via NTN.

[0178] As shown in Figures 8 and 9, if the uplink of the NTN is made to run on the TN (uplink and downlink separation), UE A can use the uplink frequency of the NTN on the TN via the first communication method (such as ultra-wideband). At the same time, the NTN can freely allocate its uplink resources to other NTN UEs for uplink transmission without worrying about resource conflicts or interference.

[0179] In this embodiment of the disclosure, the strategy of uplink and downlink multiplexing of the first resource for the same terminal device can be combined with an uplink and downlink separation mechanism. When multiplexing the first resource, the uplink and downlink of the terminal device in the first network not only use different communication methods, but also pass through different networks. For example, when multiplexing the first resource, if the uplink of the terminal device in the first network uses the first communication method and the second network, then the downlink uses the second communication method and the first network.

[0180] In one example, the second frequency is the uplink frequency allocated to the first network, and the first resource is a resource on the second frequency. The first resource is used by the first network to transmit uplink signals using the second communication method. That is, the terminal device of the first network can use the second communication method to send uplink signals to the first network using the first resource. At this time, step S402 may include: receiving downlink signals from the second network using the first communication method on the first resource.

[0181] The second network uses a first communication method to send downlink signals to terminal devices on the first network using the first resource, while the terminal devices on the first network use a second communication method to send uplink signals to the first network using the first resource. This achieves uplink / downlink separation and multiplexing of the first resource for the terminal devices on the first network. Taking the first network as NTN, the second network as TN, and the first resource as the uplink resource of the first network as an example: The same terminal device can send uplink signals on the NTN using a second communication method (e.g., ultra-wideband / quasi-ultra-wideband) on the first resource, while simultaneously receiving downlink signals from the TN using the first communication method (e.g., non-ultra-wideband). Alternatively, the same terminal device can send uplink signals on the NTN using a second communication method (e.g., non-ultra-wideband) on the first resource, while simultaneously receiving downlink signals from the TN using a second communication method (e.g., ultra-wideband / quasi-ultra-wideband) on the first resource.

[0182] Here, "terminal device of the first network" can be understood as the primary network of the terminal device, such as the network of the cell where the terminal device is accessed or camped. However, at the same time, the terminal device can send or receive information in another network, such as a second network. It should be noted that the sending of uplink signals by the terminal device of the first network using the second communication method on the first resource and the sending of downlink signals by the second network to the terminal device of the first network using the first communication method on the first resource can occur simultaneously or at different times; this disclosure does not impose any restrictions on this.

[0183] In another example, the second frequency is the downlink frequency allocated to the first network, and the first resource is a resource on the second frequency. The first resource is used by the first network for downlink signal reception using the second communication method. That is, the first network can use the second communication method on the first resource to send downlink signals to terminal devices of the first network. In this case, step S402 may include: sending uplink signals to the second network using the first communication method on the first resource.

[0184] The first network uses a second communication method on the first resource to send downlink signals to terminal devices on the first network, and the terminal devices on the first resource use a first communication method to send uplink signals to the second network, thereby achieving uplink / downlink separation and multiplexing of the first resource for the terminal devices on the first network. Taking the first network as NTN, the second network as TN, and the first resource as a resource on the downlink frequency of the first network as an example: The same terminal device can receive downlink signals on the NTN using the second communication method (e.g., ultra-wideband / quasi-ultra-wideband) on the first resource, and simultaneously send uplink signals on the TN using the first communication method (e.g., non-ultra-wideband) on the first resource. Alternatively, the same terminal device can receive downlink signals on the NTN using the first communication method (e.g., non-ultra-wideband / ultra-wideband) on the first resource, and simultaneously send uplink signals on the TN using the first communication method (e.g., non-ultra-wideband) on the first resource.

[0185] The above describes a scheme for uplink / downlink multiplexing of the first resource under the uplink / downlink separation mechanism. In one possible implementation, the uplink / downlink separation mechanism can be bound to the activation of the first resource configuration information. For example, if the terminal device receives the first resource configuration information, it automatically enables uplink / downlink separation, thus achieving the above-mentioned scheme for uplink / downlink multiplexing of the first resource under the uplink / downlink separation mechanism. Alternatively, if the terminal device does not receive the first resource configuration information, it can either enable or disable uplink / downlink separation. Regardless of whether uplink / downlink separation is enabled, the terminal device uses the second communication method for communication, without involving the first communication method.

[0186] In one possible implementation, the communication method may further include: communicating using a second communication method on either the first resource or the second resource when no first resource configuration information is received. Here, the first resource is a resource on a first frequency, where the first frequency is a frequency allocated to the second network; the second resource is a resource on a second frequency, where the second frequency is a frequency allocated to the first network.

[0187] If the first resource configuration information is not received, the terminal device of the first network may choose not to enable the uplink / downlink separation mechanism. In this case, the terminal device of the first network can use the second resource (the resource allocated on the frequency of the first network) for communication. For example, the terminal device of the first network can send uplink signals to the first network using the second communication method on the second resource, or the first network can send downlink signals to the terminal device of the first network using the second communication method on the second resource.

[0188] If the first resource configuration information is not received, the terminal device of the first network can also choose to enable uplink / downlink separation. In this case, the terminal device of the first network can communicate on the third resource (the resource on the frequency allocated to the second network). For example, the first network can send downlink signals to the terminal device of the first network using the second communication method on the second resource, and the terminal device of the first network can send uplink signals to the second network using the second communication method on the third resource. Alternatively, the second network can send downlink signals to the terminal device of the first network using the second communication method on the third resource, and the terminal device of the first network can send uplink signals to the first network using the second communication method on the second resource.

[0189] Optionally, if the uplink frequency of the NTN is used for the TN uplink, the default communication method is the first communication method described above. If the uplink frequency of the TN uses the downlink frequency of the NTN, either the first or the second communication method can be selected. That is, the TN uplink uses the uplink frequency of the NTN, with a large bandwidth and low power spectral density; the TN uplink uses the downlink frequency of the NTN, with a large bandwidth and low power spectral density, or a narrowband / wideband + high power spectral density.

[0190] Optionally, if the uplink frequency of the TN is used for the uplink of the NTN, the default communication method is the first communication method described above. If the uplink frequency of the NTN is used for the downlink of the TN, either the first communication method or the second communication method can be selected. That is, the NTN uplink uses the uplink frequency of the TN, with a large bandwidth and low power spectral density; the NTN uplink uses the downlink frequency of the TN, with a large bandwidth and low power spectral density, or a narrowband / wideband + high power spectral density.

[0191] The above communication method, after receiving the first resource configuration information, uses the first communication method indicated by the first resource configuration information to communicate on the first resource indicated by the first resource configuration information. The first resource can be reused by the first communication method and the second communication method. By distinguishing the communication methods, the reuse of the first resource is realized, which greatly improves the resource utilization rate.

[0192] In an exemplary embodiment, as shown in FIG10, a communication method is provided, which can be applied to network devices in a space-ground converged architecture. As shown in FIG10, the method may include:

[0193] Step S1001: Obtain the first resource configuration information.

[0194] The first resource configuration information can be used to indicate the first resource, which can be reused by the first communication method and the second communication method, and the first communication method and the second communication method are different. The first communication method and the second communication method can be referred to in step S401, and will not be described again here.

[0195] In one possible implementation, the first resource configuration information can be used to configure the terminal device of the first network, where the first resource is a resource on a first frequency, and the first frequency is a frequency allocated to the second network.

[0196] In one possible implementation, the communication method may further include: obtaining indication information from a second network. This indication information can be used to instruct the first network to use the first resource. Upon receiving the indication information, the first network can generate first resource configuration information.

[0197] In one example, the instruction information also includes the area and time in which the first network used the first resource.

[0198] In one possible implementation, the bandwidth of the first communication method is a first bandwidth, and the power spectral density of the first communication method is a first power spectral density; the bandwidth of the second communication method is a second bandwidth, and the power spectral density of the second communication method is a second power spectral density; the first bandwidth is greater than the second bandwidth, and / or the first power spectral density is less than the second power spectral density. Alternatively, the bandwidth of the first communication method is not less than the first bandwidth, and the power spectral density of the first communication method is not greater than the first power spectral density; the bandwidth of the second communication method is not greater than the second bandwidth, and the power spectral density of the second communication method is not less than the second power spectral density; the first bandwidth is greater than the second bandwidth, and / or the first power spectral density is less than the second power spectral density.

[0199] In this embodiment of the disclosure, the network device may first determine a first power spectral density and then determine a first bandwidth to obtain a first communication method.

[0200] In one possible implementation, the network device can determine the first power spectral density PSD1 based on the location of the terminal device, or the network device can determine the first power spectral density PSD1 based on the location relationship between the satellite and the base station.

[0201] In this embodiment of the disclosure, after given the value of PSD1, the aforementioned large bandwidth can be determined by the following method: based on the given PSD1, the bandwidth must be large enough to enable effective communication using the first communication method without interfering with communication performed using the second communication method on the same time-frequency resources. For example, in a scenario where the TN uplink uses the NTN uplink frequency, if the NTN gives a threshold for PSD1, then the requirement for bandwidth B1 is that the TN can complete effective communication or complete the required communication in the uplink using the given bandwidth B1 and the given threshold for PSD1, but without interfering with communication performed simultaneously by the NTN on the same time-frequency resources.

[0202] Regarding power spectral density, optional configurations can be made based on the location of the UE. Taking the example of using the NTN uplink frequency for TN uplink transmission, if UE1 is close to the TN base station, the power spectral density can be slightly lower when UE1 uses the NTN uplink frequency to send uplink data to the TN; if UE2 is far from the TN base station, the power spectral density can be slightly higher when UE2 uses the NTN uplink frequency to send uplink data to the TN. Optionally, the power spectral density value can be determined based on the relationship between the NTN satellites and the TN base station. For example, when UE1 uses the NTN uplink frequency to send uplink data to the TN base station, if the NTN satellites are in the communication direction from UE1 to the TN or within a certain range of the communication direction from UE1 to the TN (Figure 11, where the triangle indicates the communication direction from UE1 to gNB2 or a certain range of the communication direction), a smaller power spectral density can be used; otherwise, a slightly larger power spectral density can be used (Figure 12).

[0203] Figure 11 shows a schematic diagram of the satellite in the communication direction from the terminal to gNB2 or within a certain area in the communication direction. Figure 12 shows a schematic diagram of the satellite not in the communication direction from the terminal to gNB2 or within a certain area in the communication direction.

[0204] In another possible implementation, the network device can negotiate with the second network to obtain a power spectral density threshold, and then determine a first power spectral density based on the power spectral density threshold, wherein the first power spectral density is less than the power spectral density threshold.

[0205] Step S1002: Send the first resource configuration information.

[0206] The above communication method enables the terminal device to communicate using the first communication method indicated by the first resource configuration information by sending first resource configuration information. The first resource can be reused by the first communication method and the second communication method. By distinguishing the communication methods, the reuse of the first resource is realized, which greatly improves the resource utilization rate.

[0207] It should be noted that the first network and the second network in the embodiments of this disclosure can be interchanged. For example, NTN and TN can receive the first resource configuration from NTN or TN; the first resource configuration received from TN may be the uplink frequency configuration of NTN, or the first resource configuration received from NTN may be the uplink frequency configuration of TN; it may also be that the first resource configuration is received from TN and is the frequency configuration of TN, but the first communication method is used, or the first resource configuration is received from NTN and is the frequency configuration of NTN, but the first communication method is used.

[0208] In this embodiment, the first communication method can be an ultra-wideband (UWB) and low-power-density (LHD) communication method. UWB will be described in detail below.

[0209] Ultra-wideband (UWB) is a technology that enables communication by transmitting signals with very low power density over a very large bandwidth. It is defined as having an absolute bandwidth of 500 MHz or more, or a relative bandwidth of 20% or more (the definition used when the FCC approved UWB technology for civilian use in February 2002). The purpose of UWB is to achieve frequency reuse by transmitting signals with a very low power spectral density (no greater than -41.3 dBm) over an extremely wide bandwidth. These frequencies may be allocated to other systems. Figure 13 shows a schematic diagram of the power spectral density of ultra-wideband.

[0210] According to the regulations of the US FCC, UWB technology can transmit signals within a bandwidth of 3.1 GHz to 10.6 GHz to achieve communication with a transmit power spectral density not exceeding -41.3 dBm. It can be seen that the 3.1 GHz to 10.6 GHz frequency band includes bands used for satellite communication, as well as U-NII (National Information Infrastructure) and ISM (Industrial, Scientific and Medical Band). When using these frequency bands, UWB cannot interfere with the normal communication of existing communication systems on these bands, nor can it require these communication systems to make any coordination or concessions for the use of UWB. Therefore, it is required that the transmit power spectral density of UWB in these frequency bands not exceed -41.3 dBm.

[0211] Of course, the frequency domain resources allocated for UWB and the corresponding power spectral density limitations are different in each country. Taking China as an example:

[0212] Table 5: UWB Spectrum and Corresponding Power Spectral Density Limitations in China

[0213] In other words, according to Chinese regulations, the most suitable frequency band for UWB is likely 6GHz-9GHz. The Ministry of Industry and Information Technology's updated "Radio Management Regulations for Ultra-Wideband (UWB) Equipment" (trial operation) in 2023 expanded the UWB spectrum to 7235-8750MHz, providing a bandwidth of 1515MHz. Other frequency bands can also use UWB technology, but with lower power spectral density and more limited transmission power.

[0214] Currently, the implementation technologies of UWB mainly fall into two categories:

[0215] Pulse-based UWB: In this method, data is transmitted by sending extremely narrow pulses (e.g., 0.2ns-1.5ns). Because the pulse width is extremely narrow, the signal bandwidth is very wide. The modulation method is pulse modulation, that is, information is transmitted directly by modulating the width, amplitude, and position of the pulse.

[0216] MB-OFDM UWB: Multi-Band OFDM. This technology divides the frequency domain resources allocated to UWB into multiple sub-bands, each with a bandwidth of 528MHz. In actual use, the time-frequency code (TFC) controls which sub-band to transmit data on.

[0217] Figure 14 shows a schematic diagram of MB-OFDM UWB subband allocation. Figure 15 shows a schematic diagram of MB-OFDM-UWB subband usage. For example, in Figure 15, the first transmission uses frequency band 1, the second transmission uses frequency band 2, and the third transmission uses frequency band 3.

[0218] From the perspective of frequency reuse, ultra-wideband (UWB) actually provides a frequency reuse mechanism in the power domain. That is, it completely overlaps with other systems in the time-frequency or spatial domain, but achieves effective communication through large bandwidth and low power spectral density.

[0219] On June 27, 2023, the Ministry of Industry and Information Technology issued a new version of the "Regulations on Radio Frequency Allocation of the People's Republic of China" (Order No. 62 of the Ministry of Industry and Information Technology, hereinafter referred to as the "Regulations"). The regulations were mainly formulated based on the "Regulations on Radio Management of the People's Republic of China", the International Telecommunication Union Radio Regulations (2020 Edition) and the actual situation of radio service development in my country. The regulations officially came into effect on July 1.

[0220] The new version regarding changes to the added frequency bands for IMT systems has finally settled the long-standing issue of the 6GHz band (lower half 5925-6425MHz, upper half 6425-7125MHz), which has been of widespread concern in the industry. The upper half of the 6425-7125MHz band has been explicitly allocated to IMT (International Mobile Telecommunications). Additionally, new IMT usage rights and related constraints have been added to the millimeter-wave bands 24.75-27.5GHz, 37-43.5GHz, and 66-71GHz. The corresponding original text is as follows:

[0221] (1) Mobile services in all or part of the 6425-7125MHz frequency band are designated for use in International Mobile Telecommunications (IMT) systems. IMT systems will not be deployed or used until the application mode, frequency usage plan, compatibility and coexistence conditions between services and coordination procedures for this frequency band are determined.

[0222] (2) The mobile services in the 24.75-27.5 GHz band are designated for International Mobile Telecommunications (IMT) systems. This does not preclude the use of the band by existing services, nor has any priority been determined. The deployment and use of IMT systems must comply with relevant national radio management requirements and strictly adhere to the compatibility and coexistence conditions and coordination procedures with other services already allocated to this band. The system must not cause harmful interference to spatial services in this band. Before the relevant compatibility and coexistence conditions and coordination procedures are determined, the IMT system will not be put into actual deployment and use.

[0223] (3) Mobile services in the 37-43.5 GHz frequency band are designated for International Mobile Telecommunications (IMT) systems. The usage needs of space and terrestrial services should be considered holistically, ensuring that existing services can use the band without hindering their use and maintaining their primary or secondary status in the allocation table. The IMT system will not be deployed until the application mode, frequency usage plan, compatibility and coexistence conditions between services, and coordination procedures for this frequency band are determined.

[0224] (4) The 66-71 GHz band is designated for use by the competent authorities intending to implement the terrestrial portion of International Mobile Telecommunications (IMT). This does not preclude the use of this band by any application of services already allocated to it, nor does it establish priority in the Radio Regulations.

[0225] Optionally, and it's important to emphasize, ultra-wideband (UWB) communication (the primary communication method) may have two modes: short-range communication mode, similar to current UWB communication, with a distance of 10 meters or less; and long-range communication mode, such as that used in mobile communication networks, with a communication distance of several hundred meters. Therefore, for a terminal supporting UWB, it can be configured to use either short-range or long-range communication mode. This is because there are some differences between these two modes, such as the channel model, which may require different processing by the terminal. For example, the data link layer may differ; short-range communication uses one data link layer, while long-range communication uses another. Alternatively, the communication mode can be differentiated based on the application; for example, massive access might use long-range communication mode.

[0226] Scenario 1: China's ultra-wideband frequency configuration includes 7235-8750MHz, using a transmit power spectral density of -41.3dBm. The Ministry of Industry and Information Technology has issued a new version of the "Regulations on Radio Frequency Allocation of the People's Republic of China," explicitly allocating the upper half of the 6GHz band, 6425-7125MHz, to IMT. Assume that in the future, a portion of 6425-7125MHz will be allocated to NTN and another portion to TN. Consider allowing the UE to transmit uplink within the TN band in the 7235-8750MHz range with a power spectral density of -41.3dBm, reusing the frequency resources allocated to both NTN and TN in the 6425-7125MHz range.

[0227] In Scenario 1, the communication method may include: the UE operating in the TN, receiving configuration information from the TN, including but not limited to: instructing the UE to use all or part of the resources in the 7235-8750MHz range for uplink transmission within the TN; the communication mode being pulse modulation or spread spectrum modulation; and transmit power spectral density limitations. Based on the above configuration information, the UE transmits uplink data to the TN on the resources indicated by the configuration information, using the indicated communication mode and the specified power spectral density limitations.

[0228] Optionally, if the configuration information indicates that the UE uses all or part of the resources in the 7235-8750MHz range, including resources allocated to the NTN, the TN needs to obtain indication information from the NTN. This indication information indicates that the TN's uplink is allowed to use the NTN's uplink frequency resources. Optionally, the indication information may also include information such as the area and time (including start time and duration) in which the TN is allowed to use the NTN's uplink frequency.

[0229] Optionally, based on the above configuration information, the UE transmits uplink to the TN on the resources indicated by the configuration information, using the indicated communication method and the specified power spectral density limit. Specifically, the UE receives a control channel (possibly received from the downlink frequency of the TN), and the control channel allocates the resources indicated by the configuration information for the UE to transmit uplink on the TN; the UE transmits uplink to the TN on the resources allocated by the control channel, using the communication method indicated by the configuration information and the specified power spectral density limit.

[0230] Optionally, the communication method and power spectral density limit can be sent to the UE via the control channel.

[0231] Scenario 2: Currently, China allocates 34MHz of uplink frequency (1626.5MHz-1660.5MHz) and 30MHz of uplink frequency (2170MHz-2200MHz) to NTN in FR1. Assume that TN's uplink transmission multiplexes the 34MHz of uplink frequency (1626.5MHz-1660.5MHz) from NTN.

[0232] In Scenario 2, the communication method may include: the UE operating in the TN receives configuration information from the TN. This configuration information includes, but is not limited to: instructions for the UE to use 34MHz of uplink resources (1626.5MHz-1660.5MHz) in the NTN for uplink transmission; the communication mode being pulse modulation or spread spectrum modulation; the UE needing to occupy all of the aforementioned 34MHz resources for each transmission; and transmit power spectral density limitations. Based on this configuration information, the UE transmits uplink data to the TN using the indicated communication mode and specified power spectral density limitations on the resources specified in the configuration information. It should be noted that although the uplink frequency allocated to the NTN is 34MHz (1626.5MHz-1660.5MHz), considering link budget, in practice, a single UE will not use all of the 34MHz in each transmission; generally, the bandwidth used by a single UE in a single transmission is no more than 5MHz. This concentrates all of the UE's transmit power within a bandwidth of no more than 5MHz, effectively achieving power boosting. Therefore, the power spectral density, denoted as PSD-ntn, is likely to be relatively large, allowing the uplink signal to be better received by the satellite. If the uplink frequency allocated to the NTN is reused within the TN, the entire 34MHz can be used for a single communication by a single UE. In this case, the UE's transmit power is distributed within the 34MHz bandwidth, and the power spectral density, denoted as PSD-tn, will be much smaller. By analogy, PSD-tn can be significantly smaller than PSD-ntn.

[0233] Optionally, the TN obtains indication information from the NTN, which indicates that the TN's uplink uses the NTN's uplink frequency resources, or indicates that the TN's uplink is allowed to use the NTN's uplink frequency resources. Optionally, the indication information also includes information such as the area where the TN uses or is allowed to use the NTN's uplink frequency, and the time (including start time and duration).

[0234] Optionally, based on the above configuration information, the UE transmits uplink to the TN on the resources indicated by the configuration information, using the indicated communication method and the specified power spectral density limit. Specifically, the UE receives a control channel (possibly received from the downlink frequency of the TN), and the control channel allocates the resources indicated by the configuration information for the UE to transmit uplink on the TN; the UE transmits uplink to the TN on the resources allocated by the control channel, using the communication method indicated by the configuration information and the specified power spectral density limit.

[0235] Optionally, communication methods and power spectral density limitations can be sent to the UE via the control channel.

[0236] Optionally, the NTN reuses frequencies allocated to the TN in a similar manner. For example, if the bandwidth of the frequency allocated to the TN is B-tn (e.g., 100MHz), the NTN terminal equipment can use the frequency resources allocated to the TN, and for a single communication by a single UE, it can use the resources on the entire bandwidth B-tn (e.g., using 100MHz of bandwidth resources for each communication); however, when the TN terminal uses the frequency resources allocated to the TN, for a single communication by a single terminal, it can use resources on a portion of the bandwidth on B-tn (e.g., using only 20MHz of resources). Or conversely, for the NTN terminal equipment, when using the TN frequency resources, for a single communication by a single terminal, it can use only resources on a portion of the bandwidth on B-tn (e.g., using only 20MHz of resources); however, when the TN terminal uses the frequency resources allocated to the TN, for a single communication by a single terminal, it can use resources on the entire bandwidth B-tn (e.g., using 100MHz of bandwidth resources for each communication).

[0237] In this embodiment, a combination of high bandwidth and low power spectral density enables the reuse of frequency resources from other systems or the current system; and corresponding configuration methods, combined with uplink / downlink separation, and methods related to the location relationships of TN and NTN base stations. This embodiment can achieve time-frequency resource reuse in the power domain, significantly improving resource utilization.

Unless explicitly stated herein, there is no strict order restriction on the execution of these steps, and they can be executed in other orders. Moreover, at least some steps in the flowcharts of the above embodiments may include multiple steps or multiple stages. These steps or stages are not necessarily completed at the same time, but can be executed at different times. The execution order of these steps or stages is not necessarily sequential, but can be performed alternately or in turn with other steps or at least some of the steps or stages of other steps.
