Description

Wireless communication methods, devices and storage media

[0001] This application claims priority to Chinese Patent Application No. 202410513781.8, filed on April 23, 2024, entitled "Wireless Communication Method, Apparatus and Storage Medium", the entire contents of which are incorporated herein by reference. Technical Field

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

[0003] To achieve better and more comprehensive network coverage, future non-terrestrial networks (NTNs) such as satellite systems are evolving towards large-scale constellations. The increased constellation size leads to severe inter-beam interference, including both intra-satellite and inter-satellite interference. Intra-satellite interference can be avoided through scheduling or precoding techniques. However, how to suppress inter-satellite interference during wireless communication is a pressing issue. In other communication systems, such as 5G systems, the problem of beam interference between adjacent cells also exists. Summary of the Invention

[0004] This application provides a wireless communication method, apparatus, and storage medium to reduce communication interference between adjacent cells during wireless communication.

[0005] Firstly, embodiments of this application provide a method for wireless communication. The subject executing this method may be a first network device, which may be implemented as a network device or a component within a network device, such as a chip, a chip system, or any logic module or software capable of implementing all or part of the functions of the network device.

[0006] In one design, a first network device can receive first information from a second network device. The first information indicates a first time-domain resource, which is used to determine a second time-domain resource by combining the time offset of the first wavelength. This second time-domain resource is not used by the second network device to transmit signals on the first wavelength. Then, the first network device transmits or receives a first signal on the second time-domain resource through the second wavelength covered by the first network device, so as to avoid interference between the first network device scheduling the transmission of signals on the second wavelength and the second network device transmitting signals on the first wavelength, thereby improving the problem of beam interference between adjacent cells.

[0007] In one possible implementation, the first information may include an almost blank subframe pattern, such as an almost blank subframe (ABS) pattern, which indicates subframes in which the second network device does not transmit signals to avoid beam interference between adjacent cells.

[0008] In one possible implementation, the first network device receives second information from the second network device, the second information indicating the time offset of the first wave position, so as to achieve flexible indication of the time offset.

[0009] In one possible implementation, the first network device receives instruction information from the second network device, which indicates the receipt of second information. The first network device obtains the time offset of the first wave position by receiving the second information, which facilitates the first network device in determining the second time domain information, thereby improving the source of beam interference between adjacent cells.

[0010] In another design, the first network device receives third information from the second network device. This third information includes polarization information and interference information. The polarization information indicates the polarization mode of the signal transmitted by the second network device on the third wavelength, and the interference information indicates the degree of interference between the signal transmitted on the third wavelength and the signal transmitted by the first network device. The first network device can schedule the fourth wavelength it covers based on the third information so that the interference between the second signal transmitted on the fourth wavelength and the signal transmitted on the third wavelength is less than or equal to a first preset interference level, thereby reducing beam interference between adjacent cells.

[0011] In one possible implementation, the third information further includes: scheduling time information of the third wave position, so that the first network device can achieve high dynamic interference avoidance based on the time domain.

[0012] In one possible implementation, the third information further includes: scheduling frequency domain information of the third wavelet, so that the first network device can achieve high dynamic interference avoidance based on the frequency domain.

[0013] In one possible implementation, the third information further includes at least one of the identifier of the third wave position and / or geographical location information, so that the first network device can determine the wave position corresponding to all indicated information (such as some or all of the polarization information, interference information, scheduling time information, and scheduling frequency domain information mentioned above) to achieve flexible indication.

[0014] In one possible implementation, the interference level of the signal transmitted on the third wavelet to the signal transmitted on the fifth wavelet covered by the first network device is greater than or equal to a second preset interference level. The second network device indicates the wavelet with a higher interference level to reduce the interference of neighboring cells with lower signaling overhead.

[0017] In one possible implementation, the first information may include an almost blank subframe pattern, such as an ABS pattern, which indicates subframes in which the second network device does not transmit signals.

[0018] In one possible implementation, the second network device sends a second message indicating the time offset for sending the first bit.

[0019] In one possible implementation, the second network device sends an instruction message, which is used to instruct the transmission of a second message.

[0020] In another design, the second network device generates third information, which includes polarization information and interference information. The polarization information indicates the polarization mode of the signal transmitted by the second network device on the third wavelength, and the interference information indicates the degree of interference of the signal transmitted on the third wavelength to the signal transmitted by the first network device, and then sends the third information.

[0021] In one possible implementation, the third information further includes: scheduling time information of the third wave position; and / or, scheduling frequency domain information of the third wave position.

[0022] In one possible implementation, the third information further includes: an identifier of the third wave position; and / or, geographic location information of the third wave position.

[0055] The technical solutions in this application will now be described with reference to the accompanying drawings.

[0056] The communication method provided in this application can be applied to various communication systems, such as: Global System for Mobile Communication (GSM) system, Code Division Multiple Access (CDMA) system, Wideband Code Division Multiple Access (WCDMA) system, General Packet Radio Service (GPRS), Long Term Evolution (LTE) system, Advanced Long Term Evolution (LTE-A) system, New Radio (NR) system, evolution of NR system, LTE-based access to unlicensed spectrum (LTE-U) system, NR-based access to unlicensed spectrum (NR-U) system, NTN system, Universal Mobile Telecommunication System (UMTS), Wireless Local Area Networks (WLAN), Wireless Fidelity (WiFi), 5G system or other communication systems, or future communication systems (such as sixth-generation communication systems), etc.

[0057] The terminal equipment involved in the embodiments of this application may also be referred to as user equipment (UE), access terminal, user unit, user station, mobile station, mobile station, remote station, remote terminal, mobile device, user terminal, terminal, wireless communication equipment, user agent, or user device, etc.

[0058] Terminal devices can be stations (STs) in WLANs, cellular phones, cordless phones, Session Initiation Protocol (SIP) phones, Wireless Local Loop (WLL) stations, Personal Digital Assistant (PDA) devices, handheld devices with wireless communication capabilities, computing devices or other processing devices connected to a wireless modem, in-vehicle devices, wearable devices, terminal devices in next-generation communication systems such as NR networks, or terminal devices in future evolved Public Land Mobile Network (PLMN) networks, etc.

[0059] In the embodiments of this application, the terminal device can be deployed on land, including indoor or outdoor, handheld, wearable or vehicle-mounted; it can also be deployed on water (such as ships); and it can also be deployed in the air (such as drones, airplanes, balloons and satellites).

[0060] In the embodiments of this application, the terminal device may be a mobile phone, a tablet computer, a computer with wireless transceiver capabilities, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal device in industrial control, a wireless terminal device in self-driving, a wireless terminal device in remote medical care, a wireless terminal device in a smart grid, a drone, a wireless terminal device in transportation safety, a wireless terminal device in a smart city, or a wireless terminal device in a smart home, etc.

[0061] By way of example and not limitation, in this embodiment, the terminal device can also be a wearable device. Wearable devices, also known as wearable smart devices, are a general term for devices that utilize wearable technology to intelligently design and develop everyday wearables, such as glasses, gloves, watches, clothing, and shoes. Wearable devices are portable devices that are worn directly on the body or integrated into the user's clothing or accessories. Wearable devices are not merely hardware devices, but also achieve powerful functions through software support, data interaction, and cloud interaction. Broadly speaking, wearable smart devices include those that are feature-rich, large in size, and can achieve complete or partial functions without relying on a smartphone, such as smartwatches or smart glasses, as well as those that focus on a specific type of application function and require the use of other devices such as smartphones, such as various smart bracelets and smart jewelry for vital sign monitoring.

[0062] In key sectors such as space communication, aeronautical communication, and maritime communication, satellites play an irreplaceable role. Satellite communication boasts advantages such as long communication distances, large coverage areas, and flexible networking, providing services to both fixed and various mobile terminals. The 3rd Generation Partnership Project (3GPP) standards organization has released 5G technology standards and is researching space-ground integrated communication technologies, primarily combining existing 5G standards with satellite communication technologies to achieve full global coverage. Research has already commenced, and studies have been conducted on the architecture of satellite-5G integration.

[0063] Figure 1 is a schematic diagram of a satellite communication system provided in an embodiment of this application. As shown in Figure 1, the ground mobile terminal communicates with the satellite through a 5G New Radio access network. The 5G base station is deployed on the satellite and connected to the ground core network through a wireless link. Simultaneously, wireless links exist between the satellites to complete signaling interaction and user data transmission between base stations. In this scenario, the network equipment involved in the technical solution of this application is the base station, and the terminal equipment is the terminal shown in the figure. The network elements in Figure 1 and their interfaces are described below:

[0064] The terminal is a mobile device that supports 5G New Radio, typically such as a mobile phone or tablet. It can access the satellite network via the air interface and initiate services such as making calls and accessing the internet.

[0065] Base stations primarily provide wireless access services, allocate wireless resources to access terminals, and provide reliable wireless transmission protocols and data encryption protocols.

[0066] The core network includes services such as user access control, mobility management, session management, user security authentication, and accounting. It consists of multiple functional units, which can be divided into control plane and data plane functional entities. The Authentication Management Function (AMF) is responsible for user access management, security authentication, and mobility management. The User Plane Function (UPF) is responsible for managing user plane data transmission, traffic statistics, and other functions.

[0067] Ground station: Responsible for forwarding signaling and service data between satellite base stations and the core network.

[0068] The new air interface is the wireless link between the terminal and the base station.

[0069] The Xn interface is the interface between 5G base stations and is mainly used for signaling interactions such as handover.

[0070] The NG interface is the interface between the 5G base station and the 5G core network. It mainly interacts with the non-access stratum (NAS) signaling of the core network, as well as the user's service data.

[0071] To facilitate understanding of the embodiments of this application, the technical terms related to this application are explained below.

[0072] 1. Satellite constellation: A constellation is a system of multiple satellites that operate in Earth orbit according to a configuration to perform specific functions, such as enabling global real-time data communication.

[0073] 2. Beamforming technology: This refers to adjusting the amplitude and / or phase of a signal to give the radiated signal through an antenna array a certain directionality, thereby achieving higher antenna array gain. The signal is filtered by a spatial domain transmission filter to achieve amplitude and / or phase adjustment. Different spatial domain transmission filters using different spatial filtering parameters can achieve beams in different directions. The beam scanning covers the wave positions within the cell. The wave positions covered by the network equipment described below refer to the wave positions covered by the network equipment through beam scanning. The two expressions are used interchangeably and have the same meaning. A beam refers to the directionality of a radio wave during transmission, and a wave position refers to the location of a radio wave in space. In the embodiments of this application, the beam can be replaced by spatial filtering parameters, and the spatial filtering parameters can be replaced by a spatial transmission filter. A spatial transmission filter can also be called a spatial filter.

[0074] 3. Inter-satellite link (ISL): A link used to enable communication between satellites, allowing information transmission between them. For example, in Figure 1, 5G base stations can transmit information via ISL.

[0075] 4. Almost Blank Subframe Pattern: Such as the ABS pattern, used to indicate that the cell does not transmit data or uses low-power data transmission. The same ABS pattern is repeatedly defined to identify which subframes in the radio frame are ABS. This application does not limit the naming of the almost blank subframe pattern, and the almost blank subframe pattern can be replaced with any information used to indicate that the cell does not transmit data or uses low-power data transmission.

[0076] As constellation size increases, multi-layered networking methods have emerged, such as the Starlink Gen 2 system. Starlink Gen 2 expands its constellation size by modifying its configuration, such as by increasing orbital altitude and inclination, to achieve a more uniform capacity distribution and ensure better and more sustainable global coverage. The increased constellation size leads to severe inter-beam interference, which can include intra-satellite and inter-satellite interference. As shown in Figure 2, when adjacent satellites A and B perform beam scanning on some of their respective coverage positions to transmit signals, interference will occur. For example, if satellite A transmits signals through positions 27–30 and satellite B transmits signals through positions 1–3, interference will exist. For satellite A, the wave positions in satellite A that interfere with at least some of the wave positions covered by satellite B (such as wave positions 27-30 covered by satellite A) can be called interfering wave positions covered by satellite A. Similarly, for satellite B, the wave positions in satellite B that interfere with at least some of the wave positions covered by satellite A (such as wave positions 1-3 covered by satellite B) can be called interfering wave positions covered by satellite B. Wave positions covered by different satellites that interfere with each other can be called interfering wave positions of each other. For example, wave positions 27-30 covered by satellite A are interfering wave positions 1-3 covered by satellite B. It should be understood that similar interference problems exist in terrestrial communication systems, such as the interference problem between beams of adjacent cells. To address the above technical problems, the embodiments of this application transmit information between satellites to exchange satellite resource scheduling information, such as at least one of time domain resources, frequency domain resources, and spatial domain resources. Then, based on the exchanged resource scheduling information, the satellite schedules wave positions within its own cell for signal transmission to avoid inter-satellite interference.

[0077] It should also be understood that this application is not limited to NTN systems. When this application is applied to terrestrial communication systems, network devices transmit information to exchange resource scheduling information. Based on the exchanged resource scheduling information, the network devices schedule the beam positions within their own cells for signal transmission to resolve beam interference between cells.

[0078] The method provided in this application will be described in detail below with reference to the accompanying drawings. In the embodiments described below, wireless communication through interaction between a first network device and a second network device is used as an example. The first network device can be implemented as a network device, such as the 5G base station in Figure 1, or it can be implemented as a component (such as a chip, chip system, processor, etc.) within a network device, or as a logic module or software capable of implementing all or part of the functions of the network device. The second network device can be implemented as a network device, such as another 5G base station in Figure 1, or it can be implemented as a component (such as a chip, chip system, processor, etc.) within a network device, or as a logic module or software capable of implementing all or part of the functions of the network device. It should be understood that in a communication system, the first network device, the second network device, and the user terminals they cover can all be referred to as communication devices.

[0079] Figure 3 is a schematic flowchart of a wireless communication method 200 provided in an embodiment of this application. As shown in Figure 2, method 200 may include the following steps:

[0080] S210, the second network device sends first information to the first network device, and correspondingly, the first network device receives first information from the second network device. The first information indicates first time-domain resources, which are used to determine second time-domain resources in conjunction with the time offset of the first wave position. The second time-domain resources are not used by the second network device to transmit signals on the first wave position.

[0081] S220, the first network device transmits or receives a first signal on the second time domain resource through the second wavelet covered by the first network device.

[0082] In S210 above, the method by which the second network device sends the first information is not limited; for example, the first information can be sent via broadcast, multicast, or unicast. When the second network device broadcasts or multicasts the first information, other network devices, including the first network device, can receive the first information broadcast by the second network device. Optionally, the second network device can transmit the first information via Inter-Satellite Links (ISL). Optionally, the first information can be generated by the second network device.

[0083] For example, the first time-domain resource indicated by the first information may be a time-domain resource in which the second network device does not transmit signals, such as a subframe, slot, symbol, or other future-defined time unit in which no signal is transmitted. This application does not limit the manner in which the first information indicates the first time-domain resource. For instance, the first information may include an almost blank subframe pattern, which indicates subframes in which the second network device does not transmit signals. Referring to Figure 4, the almost blank subframe pattern can indicate whether each subframe in three radio frame lengths is used for signal transmission, such as indicating that the second network device does not transmit signals on subframes 0, 8, 6, and 4. Furthermore, the same ABS pattern can be used to repeatedly define which subframes in the radio frame are ABS.

[0084] Optionally, the ABS pattern can be applied to various network receivers, such as second network devices, third network devices, etc. The ABS pattern, or first information, can be understood as public information.

[0085] It should be noted that the first wave position can be any one of the wave positions covered by the second network device. Optionally, the first wave position can be an interfering wave position covered by the second network device. Example 1: The interfering wave position can be determined based on the geographical location of the wave position. For example, the interfering wave position can be a wave position in the edge area covered by the second network device, also known as an edge wave position. This application does not limit the scope of the edge area. The scope of the edge area can be defined based on the application scenario or service. For example, the edge area can be the outermost wave position covered by the second network device. Referring to Figure 2, taking satellite B in Figure 2 as the first network device and satellite A in Figure 2 as the second network device, the interfering wave positions covered by the second network device can include wave positions 27, 28, 29, and 30 covered by satellite A, and the interfering wave positions covered by the first network device can include wave positions 0, 1, 2, and 3 covered by satellite B. Example 2: The interference positions can be determined based on reference signal measurements. The reference signals may include, but are not limited to, reference signal receiving power (RSRP), sounding reference signal (SRS), demodulation reference signal (DMRS), channel state information reference signal (CSI-RS), cell specific reference signal (CS-RS), and synchronization system / physical broadcast channel block (SSB). For example, after measuring the reference signals, it is determined that there is interference between positions 24, 28, and 29 covered by satellite A and positions 1 and 2 covered by satellite B. The interference positions covered by the second network device may include positions 24, 28, and 29 covered by satellite A, and the interference positions covered by the first network device may include positions 1 and 2 covered by satellite B.

[0086] Optionally, the interference wave positions covered by the second network device can be determined by the first network device, or the interference wave positions covered by the second network device can be determined by the second network device, or the interference wave positions covered by the second network device can be preset, such as preset in the first network device or the second network device, or the interference wave positions covered by the second network device can be agreed upon by the protocol, such as preseting wave positions 27 and 28 covered by the second network device as interference wave positions.

[0087] Optionally, the first network device and / or the second network device can determine the degree of interference of the wavelengths covered by the second network device to at least a portion of the wavelengths covered by the first network device. This interference degree can be quantitatively expressed; for example, it can include high, slightly high, slightly low, low, etc. This application does not limit the granularity of the interference degree classification. For example, the interference degree can also include finer-grained classifications, such as interference level 1, interference level 2, interference level 3, etc., from high to low. This interference degree can be used to determine whether the wavelengths covered by the second network device are interfering wavelengths. For example, if the interference degree of a wavelength is high or slightly high, it can be determined as an interfering wavelength. Whether the wavelengths covered by the first network device are interfering wavelengths can be found in the above description of the wavelengths covered by the second network device, which will not be repeated for brevity.

[0088] For the first network device, to avoid interference with the signal transmission of the second network device on the first wavelength, the first network device needs to determine the time-domain resources on the first wavelength where the second network device does not transmit signals, i.e., the aforementioned second time-domain resources. It is understood that there is a time offset between the time the second network device transmits signals on the first wavelength and the first time-domain resources indicated by the first information. Therefore, the first network device can determine the aforementioned second time-domain resources based on the first time-domain resources and the time offset of the first wavelength. For example, referring to Figure 5, the second time-domain resources are obtained by offsetting the first time-domain resources by the time offset of the first wavelength. It should be noted that the first network device can determine the time-domain resources corresponding to each wavelength (or interfering wavelength) that are not used for signal transmission by the second network device based on the time offsets of multiple wavelengths (or interfering wavelengths) covered by the second network device. For ease of explanation, this application only uses the first wavelength as an example to describe related embodiments; other wavelengths (or interfering wavelengths) have the same or similar implementation methods as the related embodiments of the first wavelength.

[0089] Generally, the time offset of the first wavelet is associated with the relative position between the first network device and the second network device. Therefore, the time offset of the first wavelet is dedicated to the first network device in determining the second time-domain resource. The time offset of the first wavelet can be understood as a dedicated time offset, but this should not be interpreted as limiting the naming of this time offset.

[0090] As an example, the time offset of the first wave position can be indicated by a second network device. For instance, the second network device sends second information to the first network device, and correspondingly, the first network device receives second information from the first network device indicating the time offset of the first wave position.

[0091] Optionally, since the time offset of the first wavelet is dedicated to the first network device determining the second time-domain resource, the second network device can send the second information to the first network device via unicast. However, this application does not limit this; for example, the second network device can also send the second information to the first network device via broadcast or multicast.

[0092] Optionally, the second information sent by the second network device can indicate the time offset of one or more wavelengths. In a first implementation, the second information can indicate the time offset of some or all wavelengths covered by the second network device. In this case, the first network device can identify one or more interfering wavelengths among the wavelengths covered by the second network device, and determine the time-domain resources corresponding to each interfering wavelength that are not used for signal transmission by the second network device based on the time offset of each interfering wavelength. In a second implementation, the second network device can identify the interfering wavelengths among the wavelengths it covers, and indicate the time offset of one or more interfering wavelengths by sending the second information. Furthermore, the first network device can determine the time-domain resources corresponding to each interfering wavelength that are not used for signal transmission by the second network device. Referring to Table 1 below, the second information can indicate the time offset (offset_A) of wavelength A, the offset_B of wavelength B, etc., covered by the second network device.

[0093] Table 1

[0094] As another example, the time offset of the first wave position can be determined by the first network device. For example, the first network device can determine the time offset of the first wave position based on the relative position between the first network device and the second network device. Optionally, the first network device can determine the time offsets of multiple interfering wave positions covered by the second network device, and then determine the time-domain resources corresponding to each interfering wave position that are not used for signal transmission by the second network device based on the time offset of each interfering wave position. The method by which the first network device determines the interfering wave positions can be referred to the description in the previous example, and will not be repeated here for the sake of brevity.

[0095] Based on the two examples above, the second network device can indicate whether it should send second information, or whether the first network device should receive second information. This allows the first network device to obtain the time offset of the first wave position by receiving the second information when the second network device indicates it, or to determine the time offset of the first wave position when the second network device does not indicate it. For example, the second network device can send indication information to the first network device, which instructs the second network device to send the second information or instructs the first network device to receive the second information. Optionally, a value of 0 indicates that the second network device should send the second information or that the first network device should receive the second information; a value of 1 indicates that the second network device should not send the second information or that the first network device does not need to receive the second information.

[0096] In S220 above, when it is determined that the second time-domain resource is not used for the second network device to transmit signals on the first wavelength, the first network device can schedule the second wavelength covered by the first network device to send or receive the first signal on the second time-domain resource to avoid beam interference between the first and second network devices. The second wavelength can be a wavelength covered by the first network device that interferes with the first wavelength. For example, taking satellite B in Figure 2 as the first network device and satellite A in Figure 2 as the second network device, the first wavelength could be wavelength 27 covered by satellite A in Figure 2, and the second wavelength could be wavelength 0 covered by satellite B in Figure 2. However, this application does not limit this; for example, the second wavelength could also be a wavelength in the first network device that does not interfere with any wavelength of the first network device, such as wavelength 15 covered by satellite B in Figure 2.

[0097] It is understandable that the first network device can schedule the second wavelet on the second time domain resources to achieve downlink transmission, such as the first network device sending a first signal to a terminal device in the cell; or the first network device can schedule the second wavelet on the second time domain resources to achieve uplink transmission, such as the first network device receiving a first signal from a terminal device.

[0098] Therefore, in this embodiment of the application, the second network device sends first information to the first network device to indicate the first time domain resource, so that the first network device can determine the second time domain resource based on the first time domain resource and the time offset of the first wave position covered by the first network device. The second time domain resource is not used by the second network device to transmit signals on the first wave position. Then, the first network device transmits or receives the first signal on the second time domain resource through the second wave position covered by the first network device, so as to avoid interference between the first network device scheduling the second wave position to transmit signals and the second network device transmitting signals on the first wave position, thereby improving the problem of beam interference between adjacent cells.

[0099] Figure 6 is a schematic flowchart of a wireless communication method 300 provided in an embodiment of this application. As shown in Figure 6, method 300 may include the following steps:

[0100] S310, the second network device sends third information to the first network device, and correspondingly, the first network device receives the third information sent by the second network device. The third information includes polarization information and interference information.

[0101] S320, the first network device transmits or receives a second signal on a fourth wave position covered by the first network device according to the third information, and the interference level between the second signal and the signal transmitted on the third wave position is less than or equal to the first preset interference level.

[0102] The third wave position can be any one of the wave positions covered by the second network device. Optionally, the third wave position can be an interference wave position covered by the second network device. The interference wave position and the method for determining the interference wave position can be found in the description of the foregoing embodiments, and will not be repeated here for the sake of brevity. When the third wave position is an interference wave position covered by the second network device, the interference degree of the signal transmitted on the third wave position to the signal transmitted on the fifth wave position covered by the first network device is greater than or equal to the second preset interference degree. The fifth wave position and the fourth wave position can be the same wave position or different wave positions, and this application does not limit this. As mentioned above, the interference degree can be a quantitative expression. For example, the interference degree can include high, slightly high, slightly low, low, etc. This application does not limit the granularity of the interference degree division. For example, the interference degree can also include a finer granular division, such as interference degree level 1, interference degree level 2, interference degree level 3, etc., from high to low. The second preset interference degree can be, for example, high, relatively high, relatively low, etc.

[0103] For example, polarization information indicates the polarization of the signal transmitted by the second network device on the third wavelength. For instance, polarization information could indicate that the second network device can transmit signals on the third wavelength with either left-hand or right-hand polarization. Based on the polarization information, the first network device can achieve high-dynamic interference avoidance in the airspace. For example, interference information indicates the degree of interference of the signal transmitted on the third wavelength to the signal transmitted by the first network device, such as indicating the maximum (or average) degree of interference of the signal transmitted on the third wavelength to the signal transmitted on the interfering wavelengths covered by the first network device.

[0104] Optionally, the third information sent by the second network device to the first network device may indicate polarization information and interference information of at least one frequency band. This at least one frequency band may be some or all of the frequency bands covered by the second network device, or it may be some or all of a plurality of frequency bands pre-scheduled by the second network device, and the at least one frequency band includes the aforementioned third frequency band. For example, the third information may indicate polarization information and interference information of one or more frequency bands with interference levels greater than or equal to a preset interference level, such as indicating polarization information and interference information of one or more frequency bands with high or relatively high interference levels. Optionally, the third information may be generated by the second network device.

[0105] It should be understood that the wave positions covered by the second network device also include wave positions that interfere with other network devices (such as the third network device). The second network device can indicate the polarization information and interference information of at least one wave position to other network devices (such as the third network device). The implementation method is similar to the information interaction between the second network device and the first network device, and will not be described in detail for the sake of brevity.

[0106] When the second network device sends third information to the first network device to indicate the polarization and interference information of the first beam, the first network device can schedule the fourth wave position covered by the first network device according to the third information, and transmit or receive a second signal on the fourth wave position covered by the first network device. The fourth wave position can be any one of the wave positions covered by the first network device; that is, this application does not limit whether the fourth wave position is a wave position covered by the first network device that interferes with the third wave position. When there is interference between the fourth wave position and the third wave position, the first network device can schedule the fourth wave position based on the third information so that the interference level between the second signal transmitted or received through the fourth wave position and the signal transmitted on the third wave position is less than or equal to a first preset interference level. Optionally, the first preset interference level can be low, low, or no interference, etc.

[0107] It is understandable that the first network device can schedule the fourth wavelet to achieve downlink transmission, such as the first network device sending a second signal to a terminal device in the cell; or the first network device can schedule the fourth wavelet to achieve uplink transmission, such as the first network device receiving a first signal from a terminal device.

[0108] For example, taking satellite B in Figure 2 as the first network device and satellite A in Figure 2 as the second network device, assuming that there is interference between wave positions 27-30 covered by satellite A and wave positions 0-3 covered by satellite B, or that the interference level between wave positions 27-30 covered by satellite A and wave positions 0-3 covered by satellite B is high or relatively high. When the third information indicates that the polarization mode of the signal transmitted by satellite A on wave position 27 is left-handed, as one implementation, satellite B can use right-handed polarization mode to transmit or receive the second signal on the wave positions 0-3 it covers; as another implementation, satellite B can schedule wave positions that do not interfere with wave positions 27-30 covered by satellite A, or wave positions with a low or low interference level with wave positions 27-30 covered by satellite A, such as any wave position among wave positions 4-30 covered by satellite B.

[0109] In this embodiment of the application, only the polarization information and interference information of the first wave position are used as examples for illustration. It should be understood that the third information may include either polarization information or interference information.

[0110] In some embodiments, the first network device may implement high dynamic interference avoidance based on the time domain. In this case, the third information may indicate the scheduling time information of the third wavelet, which may indicate the time period for the second network device to schedule the third wavelet. Based on the scheduling time information of the third wavelet in the third information, the second network device may avoid scheduling wavelets that interfere with the third wavelet within the same time period.

[0111] Taking satellite B in Figure 2 as the first network device and satellite A in Figure 2 as the second network device, let's assume that there is interference between wave positions 27-30 covered by satellite A and wave positions 0-3 covered by satellite B, or that the interference level between wave positions 27-30 covered by satellite A and wave positions 0-3 covered by satellite B is high or relatively high. Referring to Figure 7, the third information instructs satellite A to schedule its covered wave position 27 at time T1 and its covered wave position 28 at time T2. Satellite B can schedule wave positions covered at time T1 that do not interfere with wave position 27 covered by satellite A, or wave positions with a low or very low interference level, such as any wave position 4-30 covered by satellite B. Alternatively, satellite B can schedule wave positions covered at time T1 that have a relatively high interference level with wave position 27 covered by satellite A, such as wave position 3. The method of satellite B scheduling wave positions at time T2 and other times can be found in the above description and will not be repeated for brevity.

[0112] It should be noted that the first network device can schedule the fourth wave position by combining the scheduling time information and polarization information of the third wave position. For example, during the scheduling time of the third wave position, based on the polarization mode of the signal transmitted on the third wave position indicated by the polarization information, the fourth wave position that interferes with the third wave position is scheduled, and the polarization mode of the signal transmitted on the fourth wave position is determined based on the polarization mode of the signal transmitted on the third wave position. For example, if the polarization mode of the signal transmitted on the third wave position is left-handed, the polarization mode of the signal transmitted on the fourth wave position is right-handed; or if the polarization mode of the signal transmitted on the third wave position is right-handed, the polarization mode of the signal transmitted on the fourth wave position is left-handed.

[0113] In some embodiments, the first network device may implement high dynamic interference avoidance based on the frequency domain. For example, in a cell with inter-frequency beams, the third information may indicate the scheduling frequency domain information of the third position, which may include, but is not limited to, at least one of the bandwidth part (BWP), frequency band, subcarrier, and resource block (RB). For example, the third information instructs the second network device to schedule the third position using BWP1, and the first network device may schedule the fourth position using BWP2 based on the third information.

[0114] Optionally, the first network device can combine the scheduling frequency domain information of the third wave position with at least one of the aforementioned scheduling time information and polarization information to schedule the fourth wave position. Taking satellite B in Figure 2 as the first network device and satellite A in Figure 2 as the second network device, assume that there is interference between wave positions 27-30 covered by satellite A and wave positions 0-3 covered by satellite B, or that the interference level between wave positions 27-30 covered by satellite A and wave positions 0-3 covered by satellite B is high or relatively high. Referring to Figure 8, the third information instructs satellite A to use BWP1 at time T1 to schedule wave position 27 covered by the second network device, and to use BWP2 at time T2 to schedule wave position 28 covered by the second network device. Satellite B can use a different BWP than BWP1 at time T1 to schedule the fourth wave position it covers, and this fourth wave position can be a wave position with a high or relatively high interference level with wave position 27 covered by satellite A, such as wave position 0 covered by satellite B. When satellite A uses BWP2 to schedule the wavelet at time T2, satellite B's scheduling of the fourth wavelet has a similar implementation method to the above description, and will not be repeated for the sake of brevity.

[0115] In some embodiments, the third information may include at least one of a third position identifier and / or geographic location information, so that the first network device can determine the position corresponding to all indicated information (such as some or all of the polarization information, interference information, scheduling time information, and scheduling frequency domain information mentioned above). However, this application does not limit this, for example, the third position identifier and / or geographic location information may be agreed upon by a protocol or may be preset in the first network device and / or the second network device.

[0116] Therefore, in this embodiment of the application, the second network device sends third information to the first network device to indicate the relevant scheduling parameters of the third wave position, such as polarization information and interference information. The first network device can schedule the fourth wave position it covers based on the third information, so that the interference level between the second signal transmitted on the fourth wave position and the signal transmitted on the third wave position is less than or equal to the first preset interference level, thereby reducing beam interference between adjacent cells.
