Description

Communication method, apparatus and storage medium

[0001] The present disclosure claims priority to the Chinese patent application No. 2024104780326, filed on April 19, 2024, and entitled "Communication method, apparatus and storage medium", the contents of which are hereby incorporated by reference in their entirety. TECHNICAL FIELD

[0002] The present disclosure relates to the technical field of communication, and in particular to a communication method, apparatus and storage medium. BACKGROUND

[0003] In the face of constantly innovative wireless communication technologies and continuously growing business demands, the traditional static spectrum management mode, which allocates spectrum bandwidth in certain specific areas to specific wireless communication systems, causes the contradiction between supply and demand of spectrum to become increasingly serious. Unlike the traditional static exclusive allocation spectrum management mode, spectrum sharing is to share the same idle or underutilized frequency band for data transmission on the basis of not affecting the quality of service of users, so as to realize the coexistence of different users with different permissions or multiple services.

[0004] In a satellite-ground integrated network, a multi-layer network is formed between satellites and ground base stations. With the growth of user business demands, spectrum resources become increasingly scarce, and the traditional exclusive frequency allocation mode greatly reduces the spectrum utilization efficiency. Spectrum sharing can change the frequency competition relationship between satellite communication and ground communication to a frequency coordination relationship, greatly improving the spectrum utilization rate.

[0005] The frequency reuse technology in the traditional technology, such as time division, space division and code division, needs more coordination of non-terrestrial networks and ground networks. However, the satellites in non-terrestrial networks are mobile, and the topology of non-terrestrial networks is constantly changing, making the coordination of non-terrestrial networks and ground networks relatively more troublesome.

[0113] In the embodiments of the present application, the term "and / or" describes the association relationship of the associated objects, which means that there can be three relationships, for example, A and / or B, which can represent the three cases of A alone, A and B together, and B alone. The character " / " generally represents an "or" relationship between the associated objects before and after it.

[0114] The term “plurality” in the embodiments of the present disclosure refers to two or more, and other quantifiers are similar.

[0115] The technical solutions in the embodiments of the present disclosure will be described clearly and completely below in combination with the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, and not all the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art without creative labor are within the protection scope of the present disclosure.

[0116] In a non-terrestrial network (NTN), such as a satellite network, there are two working modes, i.e., a transparent forwarding mode and a regenerative communication mode.

[0117] In the transparent forwarding mode, the satellite only transparently forwards signals without any processing, and the terminal device and the gateway station communicate. That is, the satellite only performs frequency conversion and wireless signal amplification on the uplink signal or the downlink signal, and its function is similar to that of a radio frequency relay. FIG. 1 shows a satellite communication scenario based on transparent forwarding. As shown in FIG. 1, the terminal device is connected with the gateway station through the satellite, and then accesses the data network. Among them, the connection between the terminal device and the satellite is called user link, and the connection between the satellite and the gateway station is called feeder link.

[0118] In the regenerative communication mode, the satellite can detect the information of the received signal and process and forward it, complete the function of the base station, and the satellite connects the terminal and the gateway station. That is, the satellite can perform frequency conversion, wireless signal amplification, encoding / modulation, and decoding / decoding on the uplink signal or the downlink signal. That is, the satellite can have all or part of the function of the base station (such as gNB), and can regenerate the signal.

[0119] In the non-terrestrial network, there are two types of cells, i.e., earth-fixed cells and earth-moving cells.

[0120] The ground fixed cell is that the ground coverage area of the satellite's service cell does not change with the movement of the satellite, that is, the satellite is in the "staring" mode, the satellite is moving, but the ground coverage area of the satellite's service cell does not change, and the satellite is similar to "staring" at a certain area on the ground. FIG. 2a shows an exemplary schematic diagram of a ground fixed cell. As shown in FIG. 2a, the satellite moves from T1 time to T2 time, and the coverage area of the satellite on the ground is always A, and before T1 time or after T2 time, the coverage area of the satellite on the ground is also A. The quasi-Earth fixed cell, which can also be referred to as a similar ground fixed cell, refers to that the satellite "stares" at the ground within a certain time, for example, the coverage area of the satellite on the ground is A within the interval between T1 and T2, but before T1 time or after T2 time, the coverage area of the satellite on the ground is not A. In this scenario, as the satellite moves, the angle between the satellite antenna and the ground changes, thereby ensuring that the area covered by the satellite antenna does not change.

[0121] The ground moving cell refers to that within a certain time, the ground coverage area of the satellite's service cell changes with the movement of the satellite. FIG. 2b shows an exemplary schematic diagram of a ground moving cell. As shown in FIG. 2b, the coverage area of the satellite is A at T1 time and B at T2 time. In this scenario, during the movement of the satellite, the angle between the satellite antenna and the ground hardly changes.

[0122] In the scenario of satellite-ground integration or space-air-ground integration, the harmonious coexistence of non-terrestrial networks and terrestrial networks (TN) will be pursued. This includes the coordinated use of spectrum resources to improve the utilization rate of spectrum resources. FIG. 3 shows a schematic diagram of a network architecture of satellite-ground integration.

[0123] As shown in FIG. 3, in the non-terrestrial network, it includes but is not limited to the satellite network belonging to the space-based network and the near-space network. The satellite network of the space-based network includes the geostationary earth orbit (GEO), the high earth orbit (HEO) or the highly elliptical orbit (HEO), the medium earth orbit (MEO) and the low earth orbit (LEO). The near-space network includes but is not limited to the network composed or provided by unmanned aerial vehicles, airships, aircraft, flying devices, etc. For the convenience of description, the satellite network will be mainly described in the following. However, if not specifically stated, the relevant description is also applicable to other non-terrestrial networks.

[0124] As shown in FIG. 3, the terrestrial network (TN) includes, but is not limited to, a terrestrial mobile communication network, a tracking station, a gateway station, and the like. FIG. 3 shows other parts in the network architecture of the satellite-ground integration, which can be referred to the related art, and will not be described here.

[0125] Two frequency ranges are defined in 3GPP: FR1 (Frequency Range 1) and FR2 (Frequency Range 2). Among them, FR1 is a low frequency band, and FR2 is a high frequency band. Among them, FR2 is divided into FR2-1 and FR2-2. Table 1 shows the frequency ranges of FR1 and FR2.

[0126] Table 1

[0127] In the FR1 range, the frequency resources of the 5G terrestrial network allocated by 3GPP are shown in Table 2. It should be noted that NR operating band in Table 2 represents the effective frequency band of NR, Uplink (UL) operating band represents the effective frequency band of uplink, BS receive represents network (base station) reception, UE transmit represents user equipment transmission, BS transmit represents network (base station) transmission, UE receive represents user equipment reception, F UL,low represents the lowest frequency of uplink, F UL,high represents the highest frequency of uplink, Downlink (DL) operating band represents the effective frequency band of downlink, F DL,low represents the lowest frequency of downlink, F DL,high represents the highest frequency of downlink, Duplex mode represents duplex mode. As shown in Table 2, the effective frequency band of NR includes frequency bands with band numbers n1 to n105; the duplex mode includes frequency division duplexing (FDD), time division duplexing (TDD), supplementary upload (SUL), and supplementary download (SDL).

[0128] Table 2

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

[0130] Table 3

[0131] In FR2 range, how to specifically allocate to ground network or non-terrestrial network is not defined, and the frequency band division of FR2 is shown in Table 4.

[0132] Table 4

[0133] In the face of constantly innovative wireless communication technology and the growing demand for services, the traditional static spectrum management mode allocates spectrum bandwidth in certain specific areas to specific wireless communication systems, resulting in an increasingly serious contradiction between supply and demand of spectrum. On the one hand, most of the low-frequency bands below 6GHz used for wireless communication have been basically allocated by dedicated authorization, and the scarcity of spectrum resources is increasingly evident, so the industry can only seek to promote the development and research of new frequency bands, such as millimeter wave, terahertz, etc. On the other hand, the use efficiency of most allocated frequency bands is very low, and their use is highly uneven in frequency, time, and space. Therefore, in addition to actively developing unused frequency bands, it is more important and fundamental to improve the utilization efficiency of limited spectrum resources.

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

[0135] In the satellite-ground integrated network, a multi-layer network is formed between the satellite and the ground base station. With the growth of user service demand, spectrum resources become increasingly scarce. The traditional exclusive frequency allocation method greatly reduces the efficiency of spectrum utilization. To improve the utilization efficiency of frequency resources, the signal transmission characteristics of the spatial multi-layer network need to be studied, and the soft frequency reuse method of satellite-ground communication is explored by using the difference of beams and coverage. Through interference prediction and resource coordination, the technology and method of dynamic frequency sharing reuse are further studied, while the transmission efficiency at the cell edge is improved and the interference at the cell edge is reduced.

[0136] Spectrum sharing can change the frequency competition relationship between satellite communication and ground communication to a frequency coordination relationship, greatly improving the spectrum utilization. For the medium and high frequency bands that are actively concerned by satellite communication and ground communication, due to the difference in spatial distribution of space-based and ground-based wireless transmission links, through AI assistance, terminals can better distinguish satellite communication signals and ground communication signals according to signal direction and other characteristics, realizing spatial multiplexing and interference avoidance.

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

[0138] The embodiments of the present disclosure provide a communication method and device, which realize the reuse of the first resource by distinguishing the communication mode, greatly improving the resource utilization. For the non-terrestrial network and the ground network in the satellite-ground integrated network, based on the communication method and device provided by the embodiments of the present disclosure, the non-terrestrial network and the ground network can use different communication modes to reuse resources, greatly improving the resource utilization.

[0139] Among them, the method and the device are based on the same application concept. Since the principles of the method and the device for solving problems are similar, the implementation of the device and the method can be mutually referred to, and the repeated parts will not be described again.

The wireless terminal device can be a USB storage device, other personal computer memory devices and a dongle, and can also communicate with one or more core networks (CN) through a radio access network (RAN). The wireless terminal device can be a mobile terminal device, such as a mobile phone (or called "cellular" phone) and a computer with a mobile terminal device, for example, it can be a portable, pocket, handheld, built-in computer or vehicle-mounted mobile device, which exchanges voice and / or data with a radio access network. For example, personal communication service (PCS) phones, cordless phones, session initiation protocol (SIP) phones, wireless local loop (WLL) stations, personal digital assistants (PDAs), personal computers, tablet computers, machine-type communication (MTC) terminal devices, etc. The wireless terminal device can also be called a system, a subscriber unit, a subscriber station, a mobile station, a mobile, a remote station, an access point, a remote terminal, an access terminal, a user terminal, a user agent, a user device, and a wireless access device and a router / modem that meet the limitations of the present definition, etc. The embodiments of the present disclosure are not limited.

[0142] The network device involved in the embodiments of the present disclosure can be a base station, which can include multiple cells serving terminals. According to different application scenarios, the base station can also be referred to as an access point, or can be a device in an access network that communicates with wireless terminal devices through one or more sectors over an air interface, or other names. The network device can be used to exchange received air frames with Internet Protocol (IP) packets as a router between wireless terminal devices and the rest of the access network, which can include an Internet Protocol (IP) communication network.

For example, the network device involved in the embodiments of the present disclosure can be an evolved network device (eNB or e-NodeB) in a long term evolution (LTE) system, a 5G base station (gNB) in a 5G network architecture, etc., and can also be a home evolved base station (HeNB), a relay node, a femto, a pico, a network test device, and can also be a network device of a 6G, 7G, and X-G system, which is not limited in the embodiments of the present disclosure. In some network structures, the network device can include a centralized unit (CU) node and a distributed unit (DU) node, and the centralized unit and the distributed unit can also be arranged geographically apart.

[0143] The terminal device in the embodiments of the present disclosure sends relevant information or the like to the network device, which only indicates that the terminal device sends relevant information in a wireless signal manner, and the receiving end of the relevant information is the network device. The network device can obtain the relevant information by receiving the wireless signal.

[0144] In an exemplary embodiment, as shown in FIG. 4, a communication method is provided, which can be applied to a terminal device in a star-ground fusion network as an example. As shown in FIG. 4, the method can include:

[0145] Step S401, receiving first resource configuration information.

[0146] The first resource configuration information can be used to indicate the first resource. The first resource can represent a resource that can be multiplexed by different communication modes. In the embodiments of the present disclosure, the first resource can be multiplexed by the first communication mode and the second communication mode, and the first communication mode and the second communication mode are different.

[0147] In the embodiments of the present disclosure, two different communication modes, i.e., a first communication mode and a second communication mode, can multiplex the first resource. The multiplexing can refer to multiplexing the first resource at the same time, or can also refer to multiplexing the first resource at different times. That is, when the first communication mode is used for communication on the first resource, on one hand, the communication demand of the first communication mode itself can be met, and on the other hand, the communication using the second communication mode on the first resource at the same time will not be interfered. Therefore, the multiplexing can be simultaneous use. For example, the two communication modes can multiplex the first resource can be understood as that the first resource can be used by the first communication mode and the second communication mode at the same time. However, it should be noted that when the first communication mode is used for communication on the first resource, it is not required that the communication using the second communication mode on the first resource at the same time is also performed. That is, when the first communication mode is used for communication on the first resource, on one hand, the communication demand of the first communication mode itself can be met, and on the other hand, the communication using the second communication mode on the first resource at the same time will not be interfered. This is a requirement or target, but on the first resource, there can be only communication using the first communication mode, only communication using the second communication mode, or both communication using the first communication mode and communication using the second communication mode.

[0148] In a possible implementation, the bandwidth of the first communication mode is a first bandwidth, and the power spectral density (PSD) of the first communication mode is a first power spectral density; the bandwidth of the second communication mode is a second bandwidth, and the power spectral density of the second communication mode 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 mode is not less than the first bandwidth, and the power spectral density (PSD) of the first communication mode is not greater than the first power spectral density; the bandwidth of the second communication mode is not greater than the second bandwidth, and the power spectral density of the second communication mode 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 the first power spectral density is less than the second power spectral density, or 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 mode and the second communication mode are simultaneously used for communication on the first resource, which can meet the communication demand of the first communication mode and the second communication mode itself, and will not interfere with each other, thereby ensuring the communication quality and providing the frequency utilization rate.

[0150] In one example, the first communication manner can be a large-bandwidth, low-power spectral density communication manner. The second communication manner can be a narrow-band / wide-band, high-power spectral density communication manner. The first communication manner and the second communication manner are described below respectively.

[0151] The first communication manner is characterized by large bandwidth and low power spectral density, i.e., the first bandwidth is large bandwidth, and the first power spectral density is low power spectral density. In this communication mechanism, the modulation manners that can be used include pulse modulation, or spread spectrum (such as frequency hopping spread spectrum, time hopping spread spectrum, direct sequence spread spectrum, and combined spread spectrum), or multi-band orthogonal frequency division multiplexing (OFDM) mechanism, etc. The main purpose of modulation is to expand the transmission bandwidth of the signal. At the same time, a lower power spectral density is used to transmit the signal on the above-mentioned expanded large bandwidth.

[0152] For example, the large bandwidth can be divided into ultra-wideband and quasi-ultra-wideband. Among them, the ultra-wideband can be an absolute bandwidth of 500 MHz or more at -10 dB, or a relative bandwidth of 20% or more. The quasi-ultra-wideband can be an absolute bandwidth of less than 500 MHz at -10 dB, such as 400 MHz, or 300 MHz, etc.; or a relative bandwidth of less than 20%, but not too small, such as 15%, 18%, etc. It should be noted that the large bandwidth can also be defined flexibly. For example, when the first bandwidth B1 is much larger than the second bandwidth B2, the first bandwidth B1 can be referred to as large bandwidth.

[0153] For example, the low power spectral density can be -41.3 dBm. The low power spectral density can also be defined flexibly. For example, the first power spectral density PSD1 can be much smaller than the second power spectral density PSD2. Or, the first power spectral density PSD1 can be much smaller than the power spectral density threshold PSD-threshold. The power spectral density threshold PSD-threshold can be given by one of the two networks participating in frequency multiplexing or negotiated by both. Taking the first network as TN and the second network as NTN as an example, if the uplink transmission of TN uses the uplink frequency of NTN, the power spectral density threshold PSD-threshold can be given by NTN or negotiated by NTN and TN. As long as PSD1 is less than PSD-threshold, it is OK. The above PSD-threshold threshold can ensure that when the uplink transmission of TN uses the uplink frequency of NTN, it will not interfere with the uplink reception of NTN.

[0154] The second communication mode is characterized by narrow band / wide band and high power spectral density, i.e., the second bandwidth is narrow band or wide band, and the second power spectral density is high power spectral density. The second communication mode can use a certain narrow band / wide band communication mechanism used by 3G, 4G, 5G, future 5G-A, 6G or X-G.

[0155] FIG. 5 shows an exemplary schematic diagram of power spectral density. The second communication mode uses the bandwidth and transmit power spectral density schematically shown in FIG. 5 as narrow band or wide band, and the first communication mode uses the bandwidth and transmit power spectral density schematically shown in FIG. 5 as ultra-wide band. As can be seen, the bandwidth schematically shown in FIG. 5 as ultra-wide band is much larger than the bandwidth schematically shown as narrow band and wide band, but the transmit power spectral density corresponding to the ultra-wide band is much smaller than the transmit power spectral density corresponding to the narrow band and wide band.

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

[0157] In one example, the first power spectral density is less than the second power spectral density; and 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 by the first network and the second network participating in frequency reuse.

[0158] In addition, the power spectral density at which the terminal device of the first network transmits information on the first resource can also be determined according to whether the second network device (i.e., the network device of the second network) is within a target range. The second network device and the first network device (i.e., the network device of the first network) that communicates 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 of the terminal device of the first network to the first network device (see FIGS. 11 and 12).

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

[0160] In a possible implementation, the first resource configuration information is sent by the second network. Step S401 can include receiving the first resource configuration information from the second network. The manner in which the second network determines the first resource configuration information will be described later, and will not be described 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 the first resource can be used for the uplink transmission of the TN. That is, the first resource configuration information configures a resource on the uplink frequency of the NTN, but the resource can be used for the uplink transmission of the TN. Then, the terminal device can receive the first resource configuration information from the TN, or receive the first resource configuration information from 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 the first resource can be used for the uplink transmission of the NTN. That is, the first resource configuration information configures a resource on the uplink frequency of the TN, but the resource can be used for the uplink transmission of the NTN. Then, the terminal device can receive the first resource configuration information from the NTN, or receive the first resource configuration information from the TN.

[0162] At step S402, communication is performed using the first communication manner on the first resource.

[0163] The terminal device can transmit an uplink signal using the first communication manner on the first resource, or receive a downlink signal using the first communication manner on the first resource.

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

[0165] In a 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 the embodiments of the present disclosure, the first network can multiplex a resource on a frequency 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 part of a non-terrestrial mobile communication network in 5G, future 5G-A, 6G or X-G network, or a space-based network and a near-space network shown in FIG. 3. The terrestrial network can be a part of a terrestrial mobile communication network in 3G, 4G, 5G, future 5G-A, 6G or X-G network, or a ground-based network shown in FIG. 3.

[0167] In one example, the first frequency is an uplink frequency allocated to the second network, and the first resource is a resource on the first frequency, which is used by the second network for uplink signal transmission using the second communication manner. That is, the terminal device of the second network can use the second communication manner to send an uplink signal to the second network on the first resource. At this time, step S402 can include: using the first communication manner to send an uplink signal to the first network on the first resource.

[0168] The terminal device of the first network sends an uplink signal to the first network using the first communication manner on the first resource, and the terminal device of the second network sends an uplink signal to the second network using the second communication manner on the first resource, thereby realizing uplink multiplexing of the first network on the uplink frequency allocated to the second network. It should be noted that the terminal device of the first network sends an uplink signal using the first communication manner on the first resource and the terminal device of the second network sends an uplink signal using the second communication manner on the first resource can occur at the same time, or can occur at different times, and the embodiments of the present disclosure do not limit this.

[0169] In yet 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, which is used by the second network for downlink signal reception using the second communication manner. That is, the second network can use the second communication manner to send a downlink signal to the terminal device of the second network on the first resource. At this time, step S402 can include: using the first communication manner to receive a downlink signal from the first network on the first resource.

[0170] The first network sends a downlink signal to the terminal device of the first network using the first communication manner on the first resource, and the second network sends a downlink signal to the terminal device of the second network using the second communication manner on the first resource, thereby realizing downlink multiplexing of the first network on the downlink frequency allocated to the second network. It should be noted that the first network sends a downlink signal using the first communication manner on the first resource and the second network sends a downlink signal using the second communication manner on the first resource can occur at the same time, or can occur at different times, and the embodiments of the present disclosure do not limit this.

[0171] Taking the first network as a ground network and the second network as a non-ground network as an example. FIG. 6 shows a schematic diagram of multiplexing of a ground network frequency by a non-ground network. As shown in FIG. 6, UE A and UE B are terminal devices, gNB1 and gNB2 are base stations, UE A is a terminal device of the NTN, UE B is a terminal device of the TN, and the uplink frequency of the NTN is denoted as the NTN frequency. UE A transmits an uplink signal in a second communication manner (such as a non-ultra-wideband manner), UE B transmits an uplink signal in a first communication manner (such as an ultra-wideband / ultra-wideband-like manner), and UE A and UE B both use the NTN frequency. The uplink transmission of UE B to gNB2 (TN) uses the uplink frequency of the NTN, but does not cause interference to the uplink reception of the NTN. Of course, the uplink transmission of UE B to gNB2 (TN) can also use the downlink frequency of the NTN.

[0172] Taking the first network as a non-ground network and the second network as a ground network as an example. FIG. 7 shows a schematic diagram of multiplexing of a ground network frequency by a non-ground network. As shown in FIG. 7, UE A and UE B are terminal devices, gNB1 and gNB2 are base stations, UE A is a terminal device of the NTN, UE B is a terminal device of the TN, and the uplink frequency of the TN is denoted as the TN frequency. UE B transmits an uplink signal in a second communication manner (such as a non-ultra-wideband manner), UE A transmits an uplink signal in a first communication manner (such as an ultra-wideband / ultra-wideband-like manner), and UE A and UE B both use the TN frequency. The uplink transmission of UE A to gNB1 (NTN) uses the uplink frequency of the TN, but does not cause interference to the uplink reception of the TN. Of course, the uplink transmission of UE A to gNB1 (NTN) can also use the downlink frequency of the TN.

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

[0174] In the embodiments of the present disclosure, the terminal device of the first network can multiplex uplink and downlink on the same frequency resource. Taking the first resource on the second frequency as an example, the terminal device of the first network can multiplex uplink and downlink on the first resource. When multiplexing the first resource, the terminal device of the first network needs to use different communication modes for uplink and downlink to avoid interference between uplink and downlink. For example, the terminal device of the first network can use a first communication mode to send an uplink signal on the first resource, and use a second communication mode to receive a downlink signal on the first resource (the terminal device of the first network for sending the uplink signal and receiving the downlink signal can be the same or different terminal devices); or the terminal device of the first network can use the second communication mode to send an uplink signal on the first resource, and use the first communication mode to receive a downlink signal on the first resource (the terminal device of the first network for sending the uplink signal and receiving the downlink signal can be the same or different terminal devices). In this way, by multiplexing the first resource through uplink and downlink of the same terminal device or different terminal devices, the resources can be effectively saved.

[0175] In the NTN integrated network, there is an uplink and downlink separation mechanism. For example, in the communication process of the same terminal device, the downlink goes through the non-terrestrial network and the uplink goes through the terrestrial network, or the downlink goes through the terrestrial network and the uplink goes through the non-terrestrial network.

[0176] FIG. 8 shows an uplink and downlink separation diagram in a scenario where the ground station of the non-terrestrial network is not co-located with the base station of the terrestrial network. As shown in FIG. 8, the terminal device UE A sends an uplink signal (uplink data, signaling, physical layer signal / channel) to the base station gNB2 through the TN, thereby accessing the core network and the data network. The terminal device UE A receives a downlink signal (downlink data, signaling, physical layer signal / channel) from the base station gNB1, the gateway station and the satellite through the NTN.

[0177] FIG. 9 shows an uplink and downlink separation diagram in a scenario where the ground station of the non-terrestrial network is co-located with the base station of the terrestrial network. As shown in FIG. 9, the terminal device UE A sends an uplink signal (uplink data, signaling, physical layer signal / channel) to the base station gNB through the TN, thereby accessing the core network and the data network. The terminal device UE A receives a downlink signal (downlink data, signaling, physical layer signal / channel) from the base station gNB, the gateway station and the satellite through the NTN.

[0178] As shown in FIGS. 8 and 9, if the uplink of the NTN goes through the TN (uplink and downlink separation), the UE A can use the uplink frequency of the NTN through a first communication mode (such as an ultra-wideband mode) on the uplink of the TN. At the same time, the NTN can freely allocate the uplink resource of the NTN to other NTN UEs for NTN uplink transmission without worrying about resource conflict or interference.

[0179] In the embodiments of the present disclosure, the above-mentioned strategy of multiplexing the first resources of the uplink and downlink of the same terminal device can be combined with the uplink and downlink separation mechanism. When the first resources are multiplexed, the uplink and downlink of the terminal device of the first network not only use different communication modes, but also pass through different networks. For example, when the first resources are multiplexed, the uplink of the terminal device of the first network uses the first communication mode and the second network, and the downlink uses the second communication mode and the first network.

[0180] In one example, the second frequency is the uplink frequency allocated to the first network, the first resources are resources on the second frequency, and the first resources are used for transmitting uplink signals using the second communication mode in the first network. That is, the terminal device of the first network can use the second communication mode to transmit uplink signals to the first network on the first resources. At this time, step S402 can include receiving downlink signals using the first communication mode to the second network on the first resources.

[0181] The second network transmits downlink signals to the terminal device of the first network using the first communication mode on the first resources, and the terminal device of the first network transmits uplink signals to the first network using the second communication mode on the first resources, thereby realizing the uplink and downlink separation and multiplexing the first resources of the terminal device of the first network. Taking the first network as an NTN and the second network as a TN, and the first resources as the uplink resources of the first network as an example. The same terminal device can use the second communication mode (such as a super wideband / ultra wideband mode) to transmit uplink signals on the NTN on the first resources, and at the same time, the terminal device can also use the first communication mode (such as a non-super wideband mode) to receive downlink signals from the TN on the first resources. Alternatively, the same terminal device can use the first communication mode (such as a non-super wideband mode) to transmit uplink signals on the NTN on the first resources, and at the same time, the terminal device can also use the second communication mode (such as a super wideband / ultra wideband mode) to receive downlink signals from the TN on the first resources.

[0182] Here, the "terminal device of the first network" can be understood as the first network being the main network of the terminal device, such as the network where the terminal device accesses or resides. However, at the same time, the terminal device can transmit or receive information in another network, such as the second network. It should be noted that the terminal device of the first network transmits uplink signals using the second communication mode on the first resources and the second network transmits downlink signals to the terminal device of the first network using the first communication mode on the first resources can occur at the same time or at different times, and the embodiments of the present disclosure do not limit this.

[0183] In yet another example, the second frequency is a downlink frequency allocated to the first network, the first resource is a resource on the second frequency, and the first resource is used by the first network for downlink signal reception using the second communication manner. That is, the first network can use the second communication manner to send a downlink signal to a terminal device of the first network on the first resource. At this time, step S402 can include: using the first communication manner to send an uplink signal to the second network on the first resource.

[0184] The first network uses the second communication manner to send a downlink signal to a terminal device of the first network on the first resource, and the terminal device of the first network uses the first communication manner to send an uplink signal to the second network on the first resource, thereby realizing uplink and downlink separation of the terminal device of the first network and multiplexing the first resource. Taking the first network as an NTN and the second network as a TN, and the first resource as a resource on a downlink frequency of the first network as an example. The same terminal device can use the second communication manner (such as a super wideband / ultra wideband manner) to receive a downlink signal on the NTN on the first resource, and the terminal device can also use the first communication manner (such as a non-super wideband manner) to send an uplink signal on the TN on the first resource. Alternatively, the same terminal device can use the first communication manner (such as a non-super wideband / super wideband / ultra wideband manner) to receive a downlink signal on the NTN on the first resource, and the terminal device can also use the first communication manner (such as a non-super wideband manner) to send an uplink signal on the TN on the first resource.

[0185] The above describes a scheme of downlink multiplexing on the first resource under the uplink and downlink separation mechanism. In a possible implementation, the uplink and downlink separation mechanism can be bound with the start of the first resource configuration information. For example, if the terminal device receives the first resource configuration information, the terminal device automatically enables the uplink and downlink separation, thereby realizing the scheme of downlink multiplexing on the first resource under the above uplink and downlink separation mechanism. For another example, if the terminal device does not receive the first resource configuration information, the terminal device can enable the uplink and downlink separation, or can not enable the uplink and downlink separation, and regardless of whether the uplink and downlink separation is enabled or not, the terminal device uses the second communication manner for communication, and does not involve the first communication manner.

[0186] In a possible implementation, the communication method can further include: in a case where the first resource configuration information is not received, using the second communication manner to communicate on the first resource or the second resource. The first resource is a resource on a first frequency, and the first frequency is a frequency allocated to the second network; the second resource is a resource on a second frequency, and the second frequency is a frequency allocated to the first network.

[0187] In the case that the first resource configuration information is not received, the terminal device of the first network can select not to enable the uplink-downlink separation mechanism, and in this case, the terminal device of the first network can use the second resource (the resource on the frequency allocated to the first network) for communication. For example, the terminal device of the first network can use the second communication mode to send an uplink signal to the first network on the second resource, or the first network can use the second communication mode to send a downlink signal to the terminal device of the first network on the second resource.

[0188] In the case that the first resource configuration information is not received, the terminal device of the first network can also select to enable the uplink-downlink separation, and in this case, the terminal device of the first network can use the third resource (the resource on the frequency allocated to the second network) for communication. For example, the first network can use the second communication mode to send a downlink signal to the terminal device of the first network on the second resource, and the terminal device of the first network uses the second communication mode to send an uplink signal to the second network on the third resource. Or, the second network uses the second communication mode to send a downlink signal to the terminal device of the first network on the third resource, and the terminal device of the first network uses the second communication mode to send an uplink signal to the first network on the second resource.

[0189] Optionally, if the uplink of the TN uses the uplink frequency of the NTN, the default communication mode is the first communication mode described above. If the uplink of the TN uses the downlink frequency of the NTN, the first communication mode can be selected or the second communication mode can be selected. That is, the uplink of the TN uses the uplink frequency of the NTN, large bandwidth + low power spectral density; the uplink of the TN uses the downlink frequency of the NTN, large bandwidth + low power spectral density, or narrow band / wide band + high power spectral density.

[0190] Optionally, if the uplink of the NTN uses the uplink frequency of the TN, the default communication mode is the first communication mode described above. If the uplink of the NTN uses the downlink frequency of the TN, the first communication mode can be selected or the second communication mode can be selected. That is, the uplink of the NTN uses the uplink frequency of the TN, large bandwidth + low power spectral density; the uplink of the NTN uses the downlink frequency of the TN, large bandwidth + low power spectral density, or narrow band / wide band + high power spectral density.

[0191] The above communication method, after receiving the first resource configuration information, uses the first communication mode indicated by the first resource configuration information on the first resource indicated by the first resource configuration information for communication, wherein the first resource can be multiplexed by the first communication mode and the second communication mode, and the multiplexing of the first resource is realized by distinguishing the communication modes, which greatly improves the resource utilization.

[0192] In an example embodiment, as shown in FIG. 10, a communication method is provided, which can be applied to a network device in a star-ground fusion architecture. As shown in FIG. 10, the method can include:

[0193] In step S1001, first resource configuration information is obtained.

[0194] The first resource configuration information can be used to indicate a first resource, and the first resource can be multiplexed by a first communication mode and a second communication mode, and the first communication mode and the second communication mode are different. The first communication mode and the second communication mode can refer to step S401, which will not be repeated here.

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

[0196] In a possible implementation, the communication method can further include: obtaining indication information from the second network. The indication information can be used to indicate that the first network uses the first resource. After receiving the indication information, the first network can generate the first resource configuration information.

[0197] In an example, the indication information further includes a region and a time at which the first network uses the first resource.

[0198] In a possible implementation, the bandwidth of the first communication mode is a first bandwidth, and the power spectral density of the first communication mode is a first power spectral density; the bandwidth of the second communication mode is a second bandwidth, and the power spectral density of the second communication mode 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 mode is not less than the first bandwidth, and the power spectral density of the first communication mode is not greater than the first power spectral density; the bandwidth of the second communication mode is not greater than the second bandwidth, and the power spectral density of the second communication mode 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 the embodiments of the present disclosure, the network device can first determine the first power spectral density, and then determine the first bandwidth, thereby obtaining the first communication mode.

[0200] In a possible implementation, the network device can determine the first power spectral density PSD1 according to the position of the terminal device, or the network device can determine the first power spectral density PSD1 according to the positional relationship between the satellite and the base station.

[0201] In the embodiments of the present disclosure, after the value of the PSD1 is given, the determination of the large bandwidth can be determined by the following method: on the basis of the given PSD1, the bandwidth is large enough to enable effective communication using the first communication method without causing interference to the communication using the second communication method on the same time-frequency resource. For example, in the scenario of using the uplink frequency of the NTN for the uplink of the TN, if the NTN gives a threshold value of the PSD1, the requirement of the bandwidth B1 is that the TN can complete effective communication or communication meeting the demand in the uplink through the given bandwidth B1 and the given threshold value of the PSD1, but will not cause interference to the communication of the NTN on the same time-frequency resource.

[0202] Regarding the power spectral density, optionally, different configurations can be made according to the positions of the UEs. Still taking the example of using the uplink frequency of the NTN for the uplink of the TN, if the UE1 is close to the TN base station, the power spectral density can be slightly smaller when the UE1 uses the uplink frequency of the NTN to send the uplink to the TN; if the UE2 is far away from the TN base station, the power spectral density can be slightly larger when the UE2 uses the uplink frequency of the NTN to send the uplink to the TN. Optionally, the value of the power spectral density can be determined according to the relationship between the satellite of the NTN and the TN base station. For example, when the UE1 uses the uplink frequency of the NTN to send the uplink to the TN base station, if the satellite of the NTN is in the communication direction of the UE1 to the TN uplink or within a certain range of the communication direction of the UE1 to the TN uplink (FIG. 11, the triangular mark indicates the communication direction of the UE to gNB2 or within a certain range of the communication direction), a smaller power spectral density is used, and vice versa (FIG. 12).

[0203] FIG. 11 shows a schematic diagram of the satellite in the communication direction of the terminal to gNB2 or within a certain range of the communication direction. FIG. 12 shows a schematic diagram of the satellite not in the communication direction of the terminal to gNB2 or within a certain range of 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 the first power spectral density according to the power spectral density threshold, and the first power spectral density is smaller than the power spectral density threshold.

[0205] In step S1002, the first resource configuration information is sent.

[0206] The above communication method enables the terminal device to communicate using the first communication method indicated by the first resource configuration information on the first resource indicated by the first resource configuration information, where the first resource can be multiplexed by the first communication method and the second communication method, the multiplexing of the first resource is realized by distinguishing the communication methods, and the resource utilization rate is greatly improved.

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

[0208] In the embodiments of the present disclosure, the first communication manner can be a communication manner of ultra-wideband and low power density. The ultra-wideband is described in detail below.

[0209] Ultra-wideband (UWB) is a technology that realizes communication by transmitting a signal with very low power density in a very wide bandwidth. It is defined as: -10 dB absolute bandwidth of 500 MHz or more, or relative bandwidth of 20% or more (definition when FCC approved UWB technology to enter the civil field in February 2002). The purpose of UWB is to realize frequency multiplexing by transmitting a signal with very low transmit power spectral density (not more than -41.3 dBm) on a very wide bandwidth, and these frequencies can be frequencies allocated to other systems. FIG. 13 shows a schematic diagram of the power spectral density of ultra-wideband.

[0210] According to the regulations of the United States FCC, UWB technology can transmit signals to realize communication in a bandwidth of 3.1 GHz-10.6 GHz with a transmit power spectral density of not more than -41.3 dBm. It can be seen that in the frequency band of 3.1 GHz-10.6 GHz, there are frequencies for satellite communication, U-NII (United States National Information Infrastructure) and ISM (Industrial, Scientific and Medical Band). When UWB uses these frequency bands, it cannot interfere with the normal communication of the existing communication systems on these frequency 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 on these frequency bands is not more than -41.3 dBm.

[0211] Of course, the frequency domain resources allocated by each country for UWB use and the corresponding power spectral density limit are different. For example, in China:

[0212] Table 5: China UWB spectrum and corresponding power spectral density limit

[0213] That is: in terms of China's regulations, the frequency band that may be most suitable for UWB is 6GHz-9GHz. The Ministry of Industry and Information Technology updated the "Ultra-Wideband (UWB) Device Radio Management Regulations" (Trial Operation) in 2023, updating the UWB frequency spectrum to 7235-8750MHz, with a bandwidth of 1515MHz available. Other frequency bands can also use UWB technology, but the power spectral density is lower and the transmit power is more limited.

[0214] Currently, the implementation techniques of UWB mainly include two categories:

[0215] Pulse UWB: In this mode, data transmission is performed by sending pulses with extremely narrow width (such as 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, multi-band UWB. This technology divides the frequency domain resources allocated for UWB use into multiple sub-bands, each with a bandwidth of 528MHz. In actual use, the time-frequency code (TFC) is used to control data transmission in that sub-band.

[0217] Figure 14 shows an MB-OFDM UWB sub-band division diagram. Figure 15 shows an MB-OFDM-UWB sub-band usage diagram. 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 multiplexing, ultra-wideband actually provides a frequency multiplexing mechanism in the power domain. That is, it completely overlaps with other systems in time-frequency or spatial domain, but effective communication is achieved through large bandwidth and low power spectral density.

[0219] On June 27, 2023, the Ministry of Industry and Information Technology released the new version of "Radio Frequency Division Regulations of the People's Republic of China" (Ministry of Industry and Information Technology Order No. 62, hereinafter referred to as "Division Regulations"), which was mainly formulated in accordance with "Radio Management Regulations of the People's Republic of China", "Radio Regulations" of the International Telecommunication Union (2020 edition) and the actual situation of the development of China's radio services. It came into force on July 1.

[0220] The new version of the IMT system adds the frequency band changes, the industry has been generally concerned about the 6GHz frequency band (lower half 5925-6425MHz, upper half 6425-7125MHz) finally has a definitive, the upper half of the frequency band 6425-7125MHz is clear to the IMT (International Mobile Telecommunications), and the newly added millimeter wave frequency band 24.75-27.5GHz, 37-43.5GHz, 66-71GHz IMT usage rights and related conditions. The corresponding text content is as follows:

[0221] (1) 6425-7125MHz all or part of the mobile service frequency band is determined for international mobile communication (IMT) system. Before the application mode, frequency planning, compatibility and coexistence conditions and coordination procedures of the service are determined, the IMT system is not deployed for actual use.

[0222] (2) 24.75-27.5GHz frequency band of mobile service is determined for international mobile communication (IMT) system, does not hinder the application of the business use of the frequency band, also does not determine the priority. IMT system deployment should meet the relevant requirements of national radio management, and need to strictly comply with the compatibility and coexistence conditions and coordination procedures of other services in the frequency band, and cannot cause harmful interference to the space service of the frequency band. Before the relevant compatibility and coexistence conditions and coordination procedures are determined, the IMT system is not deployed for actual use.

[0223] (3) 37-43.5GHz part of the mobile service frequency band is determined for international mobile communication (IMT) system. The use demand of space and ground service should be considered as a whole, does not hinder the application of the business use of the frequency band, does not change the primary and secondary position of the existing business in the division table. Before the application mode, frequency planning, compatibility and coexistence conditions and coordination procedures of the service are determined, the IMT system is not deployed for actual use.

[0224] (4) 66-71GHz frequency band is determined to be used by the competent department of international mobile communication (IMT) ground. Does not exclude any application of the business that has obtained the division of the frequency band, also does not determine the priority in the "Radio Regulations".

[0225] Optionally, it is emphasized that the UWB mode (the first communication mode) can have two modes: a short-range communication mode, similar to the current UWB communication mode, with a distance of 10 meters or less; and a long-range communication mode, such as used in mobile communication networks, with a communication distance of several hundred meters. Then, for a terminal supporting the first communication mode, it can be configured to use the UWB mode for short-range communication mode or long-range communication mode. Because there are some differences between the two modes, such as channel models, the terminal can need to do some different processing, such as the data link layer can be different, the short-range communication mode is one data link layer, and the long-range communication mode is another data link layer. Alternatively, according to different applications, the communication mode can be distinguished, such as if it is for massive access, it is the long-range communication mode, etc.

[0226] Scenario 1: The frequency configuration of UWB in China includes 7235-8750MHz, with a transmit power spectral density of -41.3dBm; the Ministry of Industry and Information Technology has released a new version of the "Radio Frequency Division Regulations of the People's Republic of China", which clearly divides the upper half of the 6GHz frequency band, 6425-7125MHz, to IMT. It is assumed that in the future, part of 6425-7125MHz will be allocated to NTN, and the other part will be allocated to TN. Consider allowing the UE to transmit uplink in 7235-8750MHz with a power spectral density of -41.3dBm in TN, multiplexing the frequency resources allocated to NTN and TN in the above 6425-7125MHz.

[0227] The communication method under scenario 1 can include: the UE working in TN, receiving configuration information from TN, the configuration information including but not limited to: indicating the UE to use all or part of the resources in 7235-8750MHz for TN uplink transmission; the communication mode is pulse modulation or spread spectrum modulation; the transmit power spectral density limit, etc. The UE transmits uplink to TN on the resource indicated by the configuration information, in the communication mode indicated by the configuration information, and with the specified power spectral density limit.

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

[0229] Optionally, the UE transmits uplink to the TN on the resource indicated by the configuration information, in the indicated communication manner, and with the indicated power spectral density limit, according to the configuration information. Specifically, the UE receives a control channel (possibly from the downlink frequency of the TN), and the control channel allocates the resource indicated by the configuration information for the UE to transmit uplink to the TN. The UE transmits uplink to the TN on the resource allocated by the control channel, in the communication manner indicated by the configuration information, and with the power spectral density limit indicated by the configuration information.

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

[0231] Scenario 2: Currently, China allocates 34 MHz of 1626.5-1660.5 MHz and 30 MHz of 2170-2200 MHz to NTN for uplink frequency. Assume that the TN transmits uplink in the 34 MHz of 1626.5-1660.5 MHz of the NTN uplink frequency.

[0232] The communication method under scenario 2 can include: the UE operating in the TN receives configuration information from the TN, the configuration information including but not limited to: indicating that the UE uses 34 MHz of 1626.5-1660.5 MHz of the NTN uplink frequency for TN uplink transmission; the communication manner is pulse modulation or spread spectrum modulation, and the UE needs to occupy all the above 34 MHz of resources for each transmission; the transmit power spectral density limit, etc. The UE transmits uplink to the TN on the resource indicated by the configuration information, in the indicated communication manner, and with the indicated power spectral density limit, according to the configuration information. It should be noted that although the NTN uplink frequency is allocated to 34 MHz of 1626.5-1660.5 MHz, considering the link budget, in fact, for a single UE, each transmission will not use all the above 34 MHz, and generally the bandwidth used by a single UE for single transmission is not more than 5 MHz. In this way, the total transmit power of the UE is concentrated on a bandwidth of not more than 5 MHz, which is equivalent to achieving power boosting. Therefore, the power spectral density, denoted as PSD-ntn, can be relatively large, so that the uplink signal can be better received by the satellite. If the NTN uplink frequency is multiplexed in the TN, for single communication of a single UE, all 34 MHz can be used, so that the transmit power of the UE is distributed in the bandwidth of 34 MHz, and the power spectral density, denoted as PSD-tn, will be much smaller. By analogy, it can be seen that PSD-tn can be much smaller than PSD-ntn.

[0233] Optionally, the TN obtains indication information from the NTN, the indication information indicating that the uplink of the TN uses the uplink frequency resource of the NTN, or indicating that the uplink of the TN is allowed to use the uplink frequency resource of the NTN. Optionally, the indication information further includes information such as a region where the TN uses or is allowed to use the uplink frequency of the NTN, a time (including a start time and a time length), and the like.

[0234] Optionally, the UE sends uplink to the TN according to the configuration information, in the indicated communication mode, and with the specified power spectral density limit, on the resource indicated by the configuration information. Specifically, the UE receives a control channel (which can be received from the downlink frequency of the TN), and the control channel allocates the resource indicated by the configuration information for the UE to send uplink to the TN; and the UE sends uplink to the TN in the communication mode indicated by the configuration information, and with the specified power spectral density limit, on the resource allocated by the control channel.

[0235] Optionally, the communication mode and the power spectral density limit can be sent to the UE through the control channel.

[0236] Optionally, the frequency multiplexing allocation method for the TN is similar. For example, the bandwidth of the frequency allocated to the TN is B-tn (for example, 100 MHz), and the terminal device of the NTN can use the frequency resource allocated to the TN, and for a single communication of a single UE, the entire bandwidth B-tn can be used (for example, 100 MHz bandwidth is used for each communication); however, for a single communication of a single terminal of the TN, only a part of the bandwidth B-tn can be used (for example, only 20 MHz is used). Or conversely, for a single communication of a single terminal of the NTN, only a part of the bandwidth B-tn can be used (for example, only 20 MHz is used); however, for a single communication of a single terminal of the TN, the entire bandwidth B-tn can be used (for example, 100 MHz bandwidth is used for each communication).

[0237] In the embodiments of the present disclosure, the combination of large bandwidth and low power spectral density realizes the multiplexing of other system frequency resources or frequency resources of the present system, and the corresponding configuration method combines the ideas and methods of separating uplink and downlink and the ideas and methods of the position relationship set of the TN and the NTN base station. The embodiments of the present disclosure can realize the multiplexing of time-frequency resources in the power domain, greatly improving the resource utilization rate.
