Description

Technical Field

[0001] The present application relates to the field of communication technologies, and in particular to a wireless communication method, device, and storage medium. Background Art

[0002] To achieve better and more comprehensive network coverage, future non-terrestrial networks (NTNs), such as satellite systems, are also evolving toward large-scale constellations. This increase in constellation size leads to severe interference between beams, including intra-satellite interference and inter-satellite interference. Intra-satellite interference can be avoided through scheduling or precoding technologies. For inter-satellite interference, mitigating interference during wireless communications is a pressing issue. Other communication systems, such as fifth-generation (5G) systems, also face the problem of inter-cell beam interference. Summary of the Invention

[0005] In one design, a first network device may receive first information from a second network device, where the first information indicates a first time domain resource. The first time domain resource is used to determine a second time domain resource by aggregating a time offset of a first waveband.

[0061] In some important fields such as space communication, aviation communication, and maritime communication, satellites play an irreplaceable role. Satellite communication has the characteristics of long communication distance, large coverage area, and flexible networking, and can provide services for fixed terminals and various mobile terminals. The 3rd Generation Partnership Project (3GPP) standard organization has released the 5G technical standard, which studies the integration of space and ground communication technology, mainly integrating the existing 5G standard and satellite communication technology to meet the global full coverage. The current research has been started, and the architecture of satellite and 5G integration has been studied.

[0062] Figure 1 A schematic diagram of a satellite communication system provided by the embodiments of the present application is shown in FIG. 1, in which a ground mobile terminal communicates with a satellite through a 5G new air interface access network, a 5G base station is deployed on the satellite, and is connected to the ground core network through a wireless link. At the same time, there is a wireless link between the satellites to complete the signaling interaction and user data transmission between base stations. In this scenario, the network equipment related to the technical solution of the present application is the base station, and the terminal equipment is the terminal in the figure. Figure 1 The interfaces of each network element in FIG. 1 and their descriptions are as follows: Figure 1 The terminal is a mobile device supporting the 5G new air interface, such as a mobile phone, a pad, and other mobile devices. The terminal can access the satellite network through the air interface and initiate a call, access the Internet, and other services.

[0063] The base station mainly provides wireless access services, schedules wireless resources for access terminals, and provides reliable wireless transmission protocols and data encryption protocols.

[0064]

[0065] ​The core network includes user access control, mobility management, session management, user security authentication, billing and other services. It is composed of multiple functional units, which can be divided into control plane and data plane functional entities. The access and mobility management unit (Authentication Management Function, AMF) is responsible for user access management, security authentication, and mobility management. The user plane function (user plane function, UPF) is responsible for managing user plane data transmission, traffic statistics and other functions.

[0068] Xn interface is the interface between 5G base stations and 5G base stations, mainly used for signaling interaction such as handover.

[0069] NG interface is the interface between 5G base station and 5G core network, mainly interacting with core network Non-Access Stratum (Non-Access Stratum, NAS) signaling and user service data.

[0070] In order to facilitate the understanding of the embodiments of the present application, the related technical terms of the present application are described below.

[0071] 1, satellite constellation: abbreviated as constellation, is a system composed of multiple satellites, which run on the earth orbit according to the configuration to realize specific functions, such as realizing global real-time data communication.

[0072] 2, beam forming technology: refers to adjusting the amplitude and / or phase of the signal so that the radiation signal radiated by the antenna array has a certain directivity, which can realize higher antenna array gain. The amplitude and / or phase adjustment is realized after the signal is filtered by the spatial domain transmission filter. Different spatial domain transmission filters use different spatial domain filter parameters to realize beams in different directions, and the beams scanned cover the wave positions in the cell. The wave positions covered by the network equipment described in the following are the wave positions covered by the network equipment through beam scanning, and the meanings expressed by the two expressions are consistent. Beam refers to the directivity of radio wave in the transmission process, and wave position refers to the position of radio wave in space. In the embodiments of the present application, beam can be replaced by spatial domain filter parameter, and spatial domain filter parameter can be replaced by spatial domain transmission filter. Spatial domain transmission filter can also be called spatial filter.

[0073] 3. Inter-satellite link (ISL): a link used to enable communication between satellites to enable information transfer between satellites. For example, Figure 1 Information transfer between a 5G base station and a 5G base station can be performed through an ISL.

[0074] 4. Almost blank subframe pattern: a pattern used to indicate subframes in which a cell does not transmit data or transmits data at low power, and a same ABS pattern is repeatedly defined to indicate which subframes in a radio frame are ABS. The present application does not limit the name of the almost blank subframe pattern, and the almost blank subframe pattern can be replaced by any information used to indicate subframes in which a cell does not transmit data or transmits data at low power.

[0075] With the increase in the size of the constellation, a multi-layer networking mode appears, for example, a starlink gen 2 system. The starlink gen 2 system expands the size of the constellation by modifying the constellation configuration, such as constructing more orbital altitudes, more inclination angles, and the like, to achieve more uniform capacity distribution and ensure better and more sustainable global coverage. The increase in the size of the constellation leads to serious interference between beams, which can include intra-constellation interference and inter-constellation interference. Referring to Figure 2 As shown, when adjacent satellites A and B perform beam scanning on some wave positions covered by each of them to implement signal transmission, interference will exist, for example, when satellite A transmits signals through wave positions 27-30 and satellite B transmits signals through wave positions 1-3, interference will exist. For satellite A, the wave positions in satellite A that interfere with at least part of the wave positions covered by satellite B (for example, wave positions 27-30 covered by satellite A) can be referred to as interference wave positions covered by satellite A, similarly, for satellite B, the wave positions in satellite B that interfere with at least part of the wave positions covered by satellite A (for example, wave positions 1-3 covered by satellite B) can be referred to as interference wave positions covered by satellite B, the wave positions covered by different satellites that interfere with each other can be referred to as interference wave positions of the other party, for example, wave positions 27-30 covered by satellite A are interference wave positions of wave positions 1-3 covered by satellite B. It should be understood that similar interference problems also exist in a ground communication system, for example, interference problems between beams of adjacent cells. In view of the above technical problems, the embodiments of the present application transmit information between satellites to exchange resource scheduling conditions of the satellites, such as at least one of time domain resources, frequency domain resources, and space domain resources, and then the satellites schedule wave positions in the cell for signal transmission based on the exchanged resource scheduling conditions to avoid inter-satellite interference.

[0076] It should also be understood that the present application is not limited to be applied to NTN system, when the present application is applied to terrestrial communication system, network devices transmit information to each other to exchange resource scheduling information, and then the network devices schedule beams in the cell based on the exchanged resource scheduling information to solve the beam interference between cells.

[0077] The method provided by the present application will be described in detail below with reference to the accompanying drawings. In the following embodiments, the wireless communication is implemented by the interaction between the first network device and the second network device. The first network device can be implemented as a network device, such as a 5G base station in Figure 1 , or the first network device can be implemented as a component (such as a chip, a chip system, a processor, etc.) in the network device, or a logic module or software capable of implementing all or part of the functions of the network device, etc.; the second network device can be implemented as a network device, such as another 5G base station in Figure 1 , or the second network device can be implemented as a component (such as a chip, a chip system, a processor, etc.) in the network device, or a logic module or software capable of implementing all or part of the functions of the network device. It should be understood that the first network device and the second network device and the user terminals covered thereby in the communication system can all be referred to as communication devices.

[0078] Figure 3 is a schematic flowchart of a wireless communication method 200 provided by an embodiment of the present application. As shown in Figure 2 , the method 200 can include the following steps:

[0079] S210, the second network device sends first information to the first network device, and correspondingly, the first network device receives the first information from the second network device. The first information indicates a first time domain resource, and the first time domain resource is used to determine a second time domain resource in combination with a time offset of a first beam, and the second time domain resource is not used for the second network device to transmit signals on the first beam.

[0080] S220, the first network device transmits or receives a first signal on the second time domain resource through a second beam covered by the first network device.

[0081] In the above S210, the manner in which the second network device sends the first information is not limited, for example, the first information can be sent in a broadcast, multicast or unicast manner. 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 through Inter-Satellite Links (ISL). Optionally, the first information can be generated by the second network device.

[0082] For example, the first time domain resource indicated by the first information can be a time domain resource in which the second network device does not transmit signals, such as a subframe, a slot, a symbol, or other future defined time unit in which no signals are transmitted. The present application does not limit the manner in which the first information indicates the first time domain resource, for example, the first information can include an almost blank subframe pattern, which indicates subframes in which the second network device does not transmit signals, see Figure 4 As shown, the ABS pattern can indicate whether each subframe in a length of three radio frames is used to transmit signals, such as indicating that the second network device does not transmit signals in subframe 0, subframe 8, subframe 6, and subframe 4, and further, a same ABS pattern is repeatedly defined in a radio frame to indicate which subframes are ABS.

[0083] Optionally, the ABS pattern can be applicable to each network receiving end, such as the second network device, the third network device, and the like. The ABS pattern, or the first information, can be understood as common information.

[0084] 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 interference wave position covered by the second network device. In example one, the interference wave position can be determined based on the geographical position of the wave position, for example, the interference wave position can be a wave position in an edge region covered by the second network device, which can also be referred to as an edge wave position. The present application does not limit the range of the edge region, and the range of the edge region can be defined based on an application scenario or a service, for example, the edge region can be an outermost wave position covered by the second network device, in combination with Figure 2 As shown, the first network device is Figure 2 Satellite B in FIG. 1, and the second network device is Figure 2For example, the satellite A in the above table is taken as an example, the interference wave positions covered by the second network device can include the wave positions 27, 28, 29 and 30 covered by the satellite A, and the interference wave positions covered by the first network device can include the wave positions 0, 1, 2 and 3 covered by the satellite B. In example two, the interference wave positions can be determined based on reference signal measurement, and the reference signal can include, but is 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 signal / physical broadcast channel block (SSB). For example, through reference signal measurement, it is determined that there is interference between the wave positions 24, 28 and 29 covered by the satellite A and the wave positions 1, 2 covered by the satellite B, the interference wave positions covered by the second network device can include the wave positions 24, 28 and 29 covered by the satellite A, and the interference wave positions covered by the first network device can include the wave positions 1, 2 covered by the satellite B.

[0085] 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 by a protocol, such as presetting the wave positions 27 and 28 covered by the second network device as the interference wave positions.

[0086] Optionally, the first network device and / or the second network device can determine the interference degree of the wave positions covered by the second network device to at least part of the wave positions covered by the first network device, and the interference degree can be a quantitative expression, for example, the interference degree can include high, relatively high, relatively low, low, etc. The application does not limit the granularity of the division of the interference degree, for example, the interference degree can also include finer granularity division, such as interference degree 1, interference degree 2, interference degree 3, …, from high to low. The interference degree can be used to determine whether the wave position covered by the second network device is an interference wave position, for example, the wave position can be determined as an interference wave position when the interference degree of the wave position is high and relatively high. Whether the wave position covered by the first network device is an interference wave position can be referred to the above description of the wave position covered by the second network device, and will not be described again for the sake of brevity.

[0087] For the first network device, in order to avoid interference with the second network device transmitting signals on the first wave position, the first network device needs to determine the time domain resource on which the second network device does not transmit signals on the first wave position, that is, the second time domain resource. It can be understood that there is a time offset between the time when the second network device transmits signals on the first wave position and the first time domain resource indicated by the first information, therefore, 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. For example, as shown in the following figure, the second time domain resource is obtained by offsetting the first time domain resource by the time offset of the first wave position. It should be noted that the first network device can determine the time domain resource corresponding to each wave position (or interference wave position) which is not used for the second network device to transmit signals based on the time offset of the multiple wave positions (or interference wave positions) covered by the second network device. For the convenience of description, the present application only takes the first wave position as an example to describe the related embodiments, and the other wave positions (or interference wave positions) have the same or similar implementation manner as the first wave position. Figure 5

[0088] Generally, the time offset of the first wave position is associated with the relative position between the first network device and the second network device. Therefore, the time offset of the first wave position is dedicated to the first network device to determine the second time domain resource, and the time offset of the first wave position can be understood as a dedicated time offset, of course, this should not be understood as limiting the naming of the time offset.

[0089] As an example, the time offset of the first wave position can be indicated by the second network device. For example, the second network device sends second information to the first network device, and correspondingly, the first network device receives the second information from the first network device, and the second information indicates the time offset of the first wave position.

[0090] Optionally, since the time offset of the first wave position is dedicated to the first network device to determine the second time domain resource, the second network device can send the second information to the first network device in a unicast manner. However, the present application is not limited thereto, for example, the second network device can also send the second information to the first network device in a broadcast or multicast manner.

[0091] ​Optionally, the second information sent by the second network device can indicate time offset of one or more wave positions. In a first implementation, the second information can indicate time offset of part or all wave positions covered by the second network device, in which case, the first network device can determine one or more interference wave positions in the wave positions covered by the second network device, and determine time domain resources corresponding to each interference wave position which are not used for signal transmission by the second network device based on time offset of each interference wave position; in a second implementation, the second network device can determine interference wave positions in the wave positions covered by the second network device, and indicate time offset of one or more interference wave positions by sending the second information, and thus, the first network device can determine time domain resources corresponding to each interference wave position which are not used for signal transmission by the second network device. Referring to Table 1 shown below, the second information can indicate time offset of wave position A (offset_A), offset of wave position B (offset_B), and so on, covered by the second network device.

[0092] Table 1

[0093] Wave position Time offset A offset_A B offset_B …… ……

[0094] As another example, time offset of the first wave position can be determined by the first network device, for example, the first network device can determine time offset of the first wave position based on relative position between the first network device and the second network device. Optionally, the first network device can determine time offset of multiple interference wave positions covered by the second network device, and determine time domain resources corresponding to each interference wave position which are not used for signal transmission by the second network device according to time offset of each interference wave position, in which the manner in which the first network device determines the interference wave positions can refer to the description in the foregoing examples, and will not be described again for brevity.

[0095] Based on the two examples described above, the second network device can indicate whether the second network device sends the second information, or whether the first network device receives the second information, so that the first network device obtains time offset of the first wave position by receiving the second information when the second network device indicates time offset of the first wave position, or the first network device determines time offset of the first wave position when the second network device does not indicate time offset of the first wave position. Exemplarily, the second network device can send indication information to the first network device, the indication information being used to indicate whether the second network device sends the second information or whether the first network device receives the second information. Optionally, when the value of the indication information is 0, it indicates that the second network device sends the second information or the first network device receives the second information, and when the value of the indication information is 1, it indicates that the second network device does not send the second information or the first network device does not need to receive the second information.

[0096] In the S220, when it is determined that the second time domain resource is not used for the second network device to transmit signals on the first beam, the first network device can schedule the first network device to transmit or receive the first signals on the second beam in the second time domain resource to avoid the interference between the first network device and the second network device. The second beam can be a beam of the first network device which interferes with the first beam. For example, the first network device is Figure 2 Satellite B in FIG. 1, and the second network device is Figure 2 Satellite A in FIG. 1, the first beam can be the beam 27 of the Satellite A in FIG. 1, and the second beam can be the beam 0 of the Satellite B in FIG. 1. Of course, the present application is not limited thereto, for example, the second beam can also be a beam of the first network device which does not interfere with any beam of the first network device, such as the beam 15 of the Satellite B in FIG. 1. Figure 2 Figure 2 It can be understood that the first network device schedules the second beam in the second time domain resource to realize the downlink transmission, such as the first network device transmitting the first signals to the terminal device in the cell; or the first network device schedules the second beam in the second time domain resource to realize the uplink transmission, such as the first network device receiving the first signals from the terminal device. Figure 2

[0097] Therefore, in the embodiments of the present application, the first network device can determine the second time domain resource based on the first time domain resource and the time offset between the first beam and the first time domain resource, the second time domain resource is not used for the second network device to transmit signals on the first beam, and then the first network device transmits or receives the first signals on the second beam in the second time domain resource to avoid the interference between the first network device and the second network device when the first network device schedules the second beam to transmit the signals, thereby improving the problem of the beam interference between the adjacent cells.

[0098] A schematic flowchart of a wireless communication method 300 is provided in the embodiments of the present application. As shown in FIG. 3, the method 300 can include the following steps:

[0099] Figure 6 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 including polarization information and interference information. Figure 6

[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 including polarization information and interference information.

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

[0102] The third wave position can be any one of the wave positions covered by the second network device. Alternatively, 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 foregoing embodiments, and will not be described herein again 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 on the signal transmitted on a fifth wave position covered by the first network device is greater than or equal to a second preset interference degree. The fifth wave position can be the same as or different from the fourth wave position, which is not limited in the present application. As mentioned above, the interference degree can be quantitatively expressed, for example, the interference degree can include high, relatively high, relatively low, low, etc. The present application does not limit the granularity of the interference degree, for example, the interference degree can also include finer granularity, such as interference degree 1, interference degree 2, interference degree 3, etc. from high to low. The second preset interference degree can be high, relatively high, relatively low, etc.

[0103] For example, the polarization information indicates the polarization mode of the signal transmitted on the third wave position by the second network device. For example, the polarization information can indicate that the second network device can transmit the signal on the third wave position in the left-handed or right-handed polarization mode. Based on the polarization information, the first network device can achieve high dynamic interference avoidance in space. For example, the interference information indicates the interference degree of the signal transmitted on the third wave position on the signal transmitted by the first network device, such as the maximum (or average) value of the interference degree of the signal transmitted on the third wave position on the signal transmitted on the interference wave position covered by the first network device.

[0104] Alternatively, the third information sent by the second network device to the first network device can indicate the polarization information and the interference information of at least one wave position, which can be part or all of the wave positions covered by the second network device, or the at least one wave position can be part or all of the multiple wave positions pre-scheduled by the second network device, and the at least one wave position includes the third wave position. For example, the third information can indicate the polarization information and the interference information of one or more wave positions with an interference degree greater than or equal to a preset interference degree, such as the polarization information and the interference information of one or more wave positions with an interference degree of high and relatively high. Alternatively, the third information can 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), and the second network device can indicate the polarization information and the interference information of at least one wave position to the other network devices (such as the third network device), which is similar to the information interaction between the second network device and the first network device, and will not be described again for the sake of brevity.

[0106] In a case where the second network device sends the third information to the first network device to indicate the polarization information and the interference information of the first wave beam, the first network device can schedule a fourth wave position covered by the first network device according to the third information, and send 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, the present application does not limit whether the fourth wave position is a wave position covered by the first network device and interfering with the third wave position. When the fourth wave position interferes with the third wave position, the first network device can schedule the fourth wave position based on the third information, so that the interference between the second signal sent or received through the fourth wave position and the signal transmitted on the third wave position is less than or equal to the first preset interference level. Optionally, the first preset interference level can be low, low, or no interference.

[0107] It can be understood that the first network device schedules the fourth wave position, which can realize downlink transmission, such as the first network device sending a second signal to a terminal device in the cell; or the first network device schedules the fourth wave position, which can realize uplink transmission, such as the first network device receiving a first signal from the terminal device.

[0108] For example, taking the first network device as Figure 2 For example, taking the first network device as Figure 2 For example, taking the first network device as

[0109] For example, taking the first network device as

[0110] In some embodiments, it is considered that the first network device can implement highly dynamic interference avoidance based on the time domain. In this case, the third information may indicate the scheduling time information of the third wavelength, which may indicate the time period during which the second network device schedules the third wavelength. Based on the scheduling time information of the third wavelength in the third information, the second network device may avoid scheduling wavelengths that interfere with the third wavelength during the same time period.

[0111] Still taking the first network device as Figure 2 Satellite B and the second network device are Figure 2 Taking satellite A in the example, it is assumed that there is interference between the wavelengths 27 to 30 covered by satellite A and the wavelengths 0 to 3 covered by satellite B, or the interference between the wavelengths 27 to 30 covered by satellite A and the wavelengths 0 to 3 covered by satellite B is high or relatively high. Figure 7 As shown, the third information indicates that satellite A schedules coverage of beam position 27 at time T1 and coverage of beam position 28 at time T2. Satellite B may schedule, among the beam positions covered at time T1, beam positions that do not interfere with beam position 27 covered by satellite A, or beam positions with a relatively low or low degree of interference, such as any beam positions 4 to 30 covered by satellite B. Alternatively, satellite B may schedule, among the beam positions covered at time T1, beam positions with a relatively high degree of interference with beam position 27 covered by satellite A, such as beam position 3. The manner in which satellite B schedules beam positions at time T2 and other times can be found in the above description and will not be repeated for the sake of brevity.

[0112] It should be noted that the first network device can schedule the fourth wavelength in combination with the scheduling time information and polarization information of the third wavelength. For example, within the scheduling time of the third wavelength, based on the polarization mode of the signal transmitted on the third wavelength as indicated by the polarization information, the fourth wavelength that interferes with the third wavelength is scheduled, and the polarization mode used for the signal transmitted on the fourth wavelength is determined based on the polarization mode of the signal transmitted on the third wavelength. For example, if the polarization mode of the signal transmitted on the third wavelength is left-handed, the polarization mode of the signal transmitted on the fourth wavelength is right-handed. For another example, if the polarization mode of the signal transmitted on the third wavelength is right-handed, the polarization mode of the signal transmitted on the fourth wavelength is left-handed.

[0113] In some embodiments, it is contemplated that the first network device may implement highly dynamic interference avoidance based on the frequency domain. For example, in a cell with inter-frequency beams, the third information may indicate frequency domain information for scheduling the third beam. This scheduling frequency domain information may include, but is not limited to, at least one of a bandwidth part (BWP), a frequency band, a subcarrier, and a resource block (RB). For example, the third information may indicate that the second network device uses BWP1 to schedule the third beam. Based on this third information, the first network device may use BWP2 to schedule the fourth beam.

[0114] Optionally, the first network device can schedule the fourth wave position in combination with the scheduling frequency domain information of the third wave position and at least one of the above scheduling time information and polarization information. Still taking the first network device as an example, the first network device schedules the fourth wave position in combination with the scheduling frequency domain information of the third wave position and the polarization information of the third wave position. Figure 2 The satellite B in the above embodiment and the second network device are taken as examples. The satellite A in the above embodiment is taken as an example. It is assumed that the wave positions 27-30 covered by the satellite A interfere with the wave positions 0-3 covered by the satellite B, or the interference degree between the wave positions 27-30 covered by the satellite A and the wave positions 0-3 covered by the satellite B is high or relatively high. In combination with the above interference information, the first network device can schedule the fourth wave position in combination with the scheduling frequency domain information of the third wave position and the polarization information of the third wave position. Figure 2 The satellite A in the above embodiment is taken as an example. It is assumed that the wave positions 27-30 covered by the satellite A interfere with the wave positions 0-3 covered by the satellite B, or the interference degree between the wave positions 27-30 covered by the satellite A and the wave positions 0-3 covered by the satellite B is high or relatively high. In combination with the above interference information, the first network device can schedule the fourth wave position in combination with the scheduling frequency domain information of the third wave position and the polarization information of the third wave position. Figure 8 As shown in the above embodiment, the third information indicates that the satellite A adopts the BWP1 at the time T1 to schedule the wave position 27 covered by the second network device, adopts the BWP2 at the time T2 to schedule the wave position 28 covered by the second network device, and the satellite B can adopt a BWP different from the BWP1 at the time T1 to schedule the fourth wave position covered by the satellite B, and the fourth wave position can be a wave position with a high or relatively high interference degree with the wave position 27 covered by the satellite A, such as the wave position 0 covered by the satellite B. When the satellite A adopts the BWP2 to schedule the wave position at the time T2, the satellite B can schedule the fourth wave position in a manner similar to the above description, and for brevity, the description is not repeated.

[0115] In some embodiments, the third information can include at least one of the identification of the third wave position and / or the geographic position information, so that the first network device determines the wave positions corresponding to all the indicated information (such as part or all of the above polarization information, interference information, scheduling time information, and scheduling frequency domain information). However, the present application is not limited thereto, for example, the identification of the third wave position and / or the geographic position information can be agreed by a protocol, or can be preset in the first network device and / or the second network device.

[0116] Therefore, in the embodiments of the present application, the second network device sends the third information to the first network device to indicate the related scheduling parameters of the third wave position, such as the polarization information and the interference information, and the first network device can schedule the fourth wave position covered by the first network device based on the third information, so that the interference degree 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 degree, so as to reduce the beam interference between adjacent cells.
