Technical Field

[0002] Embodiments of the present disclosure generally relate to the field of wireless communications, and specifically to electronic devices, distributed unit devices, wireless communication methods, and storage media. More specifically, the present disclosure relates to an electronic device as a base station device in a wireless communication system, an electronic device as a centralized unit (CU) device in a wireless communication system, an electronic device as a distributed unit (DU) device in a wireless communication system, a wireless communication method performed by a base station device in a wireless communication system, a wireless communication method performed by a CU device in a wireless communication system, a wireless communication method performed by a DU device in a wireless communication system, and a computer-readable storage medium. Background Art

[0003] In 5G communication systems, electromagnetic waves can be propagated in a specific direction, so that user devices in different spatial directions can use all spectrum resources to communicate uninterruptedly at the same time, which is called space-division multiple access (SDMA). The technology of propagating electromagnetic waves in a specific direction is called beamforming technology. Through beamforming technology, the energy of the wireless signal is focused to form a directional beam. Usually, the antenna directivity can be represented by the antenna pattern, because the antenna direction Figure 1 The antenna radiation pattern is generally petal-shaped, so it is also called a lobe pattern. In the antenna radiation pattern, the lobe with the largest radiation intensity is called the main lobe, and the remaining lobes are called secondary lobes or side lobes.

[0004] In wireless communication systems including TN (Terrestrial network) and NTN (Non-terrestrial network), all or part of the functions of the base station equipment can be placed on the satellite equipment, and the user equipment can communicate with the base station equipment located on the satellite equipment. As more and more satellite equipment provide services for user equipment, the intervals between satellite equipment are getting smaller and smaller. If the transmitting antenna of the user equipment has a wider main lobe, or the transmitting antenna of the user equipment has a stronger side lobe, energy leakage will occur. In other words, the uplink signal from the user equipment to the satellite equipment that provides services for the user equipment may interfere with the adjacent satellite equipment.

[0005] Therefore, it is necessary to propose a technical solution to eliminate or avoid the interference of the uplink signal from the user equipment to the satellite equipment providing services to the user equipment to other satellite equipment. Summary of the invention

[0045] <1. Description of the scene>

[0046] Figure 1 Schematic diagram showing the application scenario of the present disclosure. Figure 1 As shown, the user equipment located on the ground can send an uplink signal to the network side equipment, such as a gNB or DU device, that provides services for it. Here, the gNB or DU device can be located on the satellite device, and there are one or more other gNB / DUs next to the gNB / DU that provides services for the user equipment. Figure 1 A main lobe and two side lobes of the transmit antenna of the user equipment are shown in FIG. Figure 1 In the scenario shown, if the UE’s transmit antenna has a wider main lobe, or the UE’s transmit antenna has a stronger side lobe, energy leakage will occur, i.e., interference signals will be generated to other gNB / DUs other than the serving gNB / DU.

[0047] In view of such a scenario, the present disclosure proposes a network-side device (including a base station device, a CU device and a DU device) in a wireless communication system, a wireless communication method performed by the network-side device in the wireless communication system, and a computer-readable storage medium to eliminate or avoid interference of an uplink signal from a user device to a satellite device providing services thereto to other satellite devices.

[0048] According to an embodiment of the present disclosure, the wireless communication system may be a 5G (5th generation) or 6G (6th generation) communication system. Specifically, the wireless communication system according to the present disclosure may be a satellite communication system including TN and NTN.

[0049] The network side device according to the present disclosure may be any type of TRP (Transmit and Receive Port), or a base station device, such as an eNB or a gNB. The gNB may include a gNB-CU and a gNB-DU, both of which are integrated in the gNB so that the gNB can complete the communication with the user equipment. The gNB-CU plays the role of an information center and a management unit within the gNB service range, and is responsible for exchanging control information with the user equipment within the gNB service range, while the gNB-DU is responsible for exchanging data information with the user equipment within the gNB service range. That is to say, in Figure 1 In the scenario shown, both the gNB-CU and the gNB-DU can be integrated into the gNB, and the gNB can be placed in the satellite device. According to the embodiment of the present disclosure, the interference of the uplink signal from the user equipment to the gNB providing service to other gNBs can be eliminated or avoided.

[0050] The network side device according to the present disclosure may also be a CU device or a DU device. Here, the CU device and the DU device may be separate, that is, located in separate devices. The CU device is responsible for the transmission of control information between the user device and the DU device is responsible for the transmission of data information between the user device and the CU device, and one CU device may manage the resources of multiple DU devices. That is, in Figure 1 In the scenario shown, the CU device and the DU device are separated, and the DU device is placed in the satellite device. According to the embodiments of the present disclosure, the interference of the uplink signal from the user equipment to the DU device providing service thereto to other DU devices can be eliminated or avoided.

[0051] The DU device according to the present disclosure may be a satellite device in a satellite communication system. Specifically, the DU device may be a LEO (Low Earth Orbit) satellite device, a MEO (Medium Earth Orbit) satellite device, a HEO (Highly Elliptical Orbiting) satellite device, and a HAPS (High Altitude Platform Station).

[0052] The CU device according to the present disclosure may be a satellite device in a satellite communication system. Specifically, the CU device may be a GEO (Geosynchronous Orbit) satellite device. The CU device according to the present disclosure may also be a ground base station device in a satellite communication system, for example, an eNB or a gNB.

[0053] The user equipment according to the present disclosure may be a mobile terminal (such as a smart phone, a tablet personal computer (PC), a notebook PC, a portable game terminal, a portable / dongle-type mobile router, and a digital camera) or a vehicle-mounted terminal (such as a car navigation device). The user equipment may also be implemented as a terminal that performs machine-to-machine (M2M) communication (also referred to as a machine type communication (MTC) terminal). In addition, the user equipment may be a wireless communication module (such as an integrated circuit module including a single chip) installed on each of the above-mentioned terminals.

[0054] <2. gNB Configuration Example>

[0055] Figure 2 2 is a block diagram showing an example of a configuration of an electronic device 200 according to an embodiment of the present disclosure. The electronic device 200 here can be used as a network side device in a wireless communication system, specifically as a base station device in a wireless communication system, such as a gNB, that is, a gNB integrating a gNB-CU and a gNB-DU. According to an embodiment of the present disclosure, the gNB can be any type of satellite device or high-altitude platform.

[0056] like Figure 2 As shown, the electronic device 200 may include a communication unit 210 and an interference determination unit 220 .

[0057] Here, each unit of the electronic device 200 may be included in a processing circuit. It should be noted that the electronic device 200 may include one processing circuit or multiple processing circuits. Further, the processing circuit may include various discrete functional units to perform various functions and / or operations. It should be noted that these functional units may be physical entities or logical entities, and units with different names may be implemented by the same physical entity.

[0058] According to an embodiment of the present disclosure, the electronic device 200 may receive, through the communication unit 210 , a spatial radiation parameter related to a spatial radiation characteristic of a transmitting antenna of a user equipment.

[0059] According to an embodiment of the present disclosure, the interference determination unit 220 may determine whether an uplink signal from the user equipment generates interference to other electronic devices according to the spatial radiation parameters of the user equipment.

[0060] As described above, according to the electronic device 200 of the embodiment of the present disclosure, it is possible to determine whether the uplink signal from the user equipment interferes with other electronic devices according to the spatial radiation parameters of the user equipment. In this way, a reasonable interference coordination strategy can be formulated to eliminate or avoid interference of the uplink signal from the user equipment to the electronic device 200 providing services thereto to other electronic devices.

[0061] According to an embodiment of the present disclosure, the electronic device 200 may be a network-side device that provides services for the user equipment, and the electronic device 200 may be a satellite device. Further, the uplink signal from the user equipment refers to the uplink signal sent by the user equipment to the electronic device 200. In addition, other electronic devices may also be satellite devices, for example, other gNBs other than the electronic device 200 that provides services for the user equipment. That is, according to an embodiment of the present disclosure, the interference determination unit 220 may determine whether the uplink signal from the user equipment to the electronic device 200 generates interference to other satellite devices other than the electronic device 200 that provides services for the user equipment based on the spatial radiation parameters of the user equipment.

[0062] According to an embodiment of the present disclosure, the spatial radiation parameters of the user equipment include the radiation direction parameters of the main beam of the transmitting antenna and the polarization direction parameters of the transmitting antenna. According to an embodiment of the present disclosure, the main beam includes at least two strong side lobes.

[0063] Here, the spatial radiation parameters may include the radiation direction parameters of at least two strong side lobes of the transmitting antenna. Since the side lobes are symmetrically distributed on both sides of the main lobe in the antenna radiation pattern, the number of side lobes included in the spatial radiation parameters is generally an even number, such as 2, 4, .... Further, the strong side lobes included in the spatial radiation parameters may be adjacent to the main lobe. That is, when the spatial radiation parameters include the radiation direction parameters of two strong side lobes, the two strong side lobes are two strong side lobes located adjacent to the main lobe on both sides of the main lobe, and there is one strong side lobe on each side of the main lobe; when the spatial radiation parameters include the radiation direction parameters of four strong side lobes, the four strong side lobes are four strong side lobes located adjacent to the main lobe on both sides of the main lobe, that is, there are two strong side lobes on each side of the main lobe; and so on.

[0064] According to an embodiment of the present disclosure, the main beam may further include a main lobe. Further, the spatial radiation parameters of the user equipment may further include a radiation direction parameter of the main lobe. In addition, the spatial radiation parameters of the user equipment may further include a beam width parameter of the main beam. That is, the spatial radiation parameters of the user equipment may further include one or more of the following parameters: a radiation direction parameter of the main lobe, a beam width parameter of the main lobe, and beam width parameters of at least two strong side lobes.

[0065] According to an embodiment of the present disclosure, the electronic device 200 may receive the spatial radiation parameters via PUCCH (Physical Uplink Control Channel) or PUSCH (Physical Uplink Share Channel). In addition, when reporting the spatial radiation parameters, the user equipment may use the ECEF (Earth-Centered Earth-Fixed) coordinate system.

[0066] According to the embodiments of the present disclosure, Figure 2 As shown, the electronic device 200 may further include a configuration unit 230 for configuring the content and transmission method of the space radiation parameters.

[0067] According to an embodiment of the present disclosure, the configuration unit 230 may configure the number of main beams included in the spatial radiation parameters for the user equipment; or the number of strong side lobes included in the spatial radiation parameters. In this way, the user equipment may determine which radiation direction parameters (and optionally beam width parameters) of strong side lobes need to be included in the spatial radiation parameters according to the configuration of the configuration unit 230.

[0068] According to an embodiment of the present disclosure, the configuration unit 230 may also configure a range of the beam width of the main lobe and / or a range of the beam width of the strong side lobe for the user equipment. For example, the configuration unit 230 may configure an angular range of the beam width of the main lobe and / or an angular range of the beam width of the strong side lobe for the user equipment. As a non-limiting example, the range of the beam width of the main lobe may be an xdB width, and the range of the beam width of the strong side lobe may also be an xdB width. Preferably, x=3. That is, the width of the angle between the two half-power points of the beam is called the beam width, that is, the width of the angle formed by 3dB below the peak in the radiation pattern of the transmitting antenna is called the beam width.

[0069] According to an embodiment of the present disclosure, the electronic device 200 may periodically receive the spatial radiation parameter from the user equipment. In this case, the configuration unit 230 may also configure the period for the user equipment to report the spatial radiation parameter.

[0070] According to an embodiment of the present disclosure, the configuration unit 230 may configure the content and sending mode of the spatial radiation parameter for the user equipment, and may generate configuration information, the configuration information including information about the content and sending mode of the spatial radiation parameter configured for the user equipment by the configuration unit 230. Further, the electronic device 200 may send the configuration information to the user equipment, whereby the user equipment may send the spatial radiation parameter according to the configuration information from the electronic device 200.

[0071] According to the embodiments of the present disclosure, since the polarization direction parameter of the transmitting antenna of the user equipment is unchanged, the user equipment can report the polarization direction parameter to the electronic device 200 when accessing the network, and there is no need to report the parameter again later. For other parameters in the spatial radiation parameter, the user equipment can report periodically or event-based.

[0072] Further, according to an embodiment of the present disclosure, since the electronic device 200 as a network side device can be a satellite device with a fixed orbit, the user device can adjust its beam direction according to the orbit of the electronic device 200 so that the radiation direction of the main lobe is aligned with the electronic device 200. Therefore, the user device can also report the spatial radiation parameters to the electronic device 200 when accessing the network, and there is no need to report periodically afterwards. The electronic device 200 can predict the updated spatial radiation parameters of the user device at any time based on the spatial radiation parameters reported by the user device when accessing the network.

[0073] According to an embodiment of the present disclosure, the various spatial radiation parameters introduced in the foregoing are parameters related to the beamforming of the user equipment, which are closely related to the spatial radiation characteristics of the transmitting antenna of the user equipment. Therefore, the interference determination unit 220 can determine whether the uplink signal from the user equipment will interfere with other electronic devices based on the spatial radiation parameters.

[0074] According to an embodiment of the present disclosure, the electronic device 200 may receive the ephemeris information of other electronic devices through the communication unit 210. For example, the electronic device 200 may periodically exchange ephemeris information with an adjacent satellite device through the communication unit 210. That is, the electronic device 200 may periodically receive the ephemeris information of the adjacent satellite device from the adjacent satellite device, or may periodically send the ephemeris information of the electronic device 200 to the adjacent satellite device.

[0075] According to an embodiment of the present disclosure, the interference determination unit 220 can determine whether an uplink signal from a user equipment generates interference to other electronic devices based on the spatial radiation parameters of the user equipment and the ephemeris information of other electronic devices. Specifically, the interference determination unit 220 can determine which other electronic devices the uplink signal of the user equipment will generate interference to based on the spatial radiation parameters of the user equipment and the ephemeris information of other adjacent electronic devices.

[0076] Here, the interference determination unit 220 can determine the location information of other electronic devices at any time according to the ephemeris information of other electronic devices, and determine the signal strength of the uplink signal from the user equipment to the electronic device 200 at other electronic devices at any time according to the spatial radiation parameters of the user equipment, so as to determine whether interference is caused to the other electronic devices. Here, the interference determination unit 220 can determine the signal strength and determine the interference according to any method known in the art, and the present disclosure is not limited to this.

[0077] According to an embodiment of the present disclosure, when the frequency domain resources of the user equipment are different from the frequency domain resources of other electronic devices, the uplink signal from the user equipment will not interfere with other electronic devices. Only when the frequency domain resources used by the user equipment and the frequency domain resources used by other electronic devices are the same, if the signal strength of the uplink signal from the user equipment at the other electronic devices is strong enough, the other electronic devices will be interfered. Therefore, the interference determination unit 220 can also determine whether the uplink signal from the user equipment interferes with other electronic devices based on the spatial radiation parameters of the user equipment, the frequency domain resources of the user equipment, and the frequency domain resources of other electronic devices.

[0078] Specifically, when the frequency domain resources of the user equipment are the same as the frequency domain resources of other electronic devices, the interference determination unit 220 determines whether the uplink signal from the user equipment generates interference to other electronic devices according to the spatial radiation parameters of the user equipment as described above. Similarly, the interference determination unit 220 can also determine whether the uplink signal from the user equipment generates interference to other electronic devices according to the spatial radiation parameters of the user equipment and the ephemeris information of other electronic devices.

[0079] According to an embodiment of the present disclosure, since the electronic device 200 provides services for the user equipment, the electronic device 200 can allocate frequency domain resources for the user equipment. That is, the electronic device 200 knows the frequency domain resources of the user equipment. Further, the electronic device 200 can obtain the frequency domain resources of other electronic devices from other electronic devices through the communication unit 210. For example, the electronic device 200 and other electronic devices can exchange frequency domain resources when exchanging ephemeris information. Optionally, other electronic devices can also send their frequency domain resource information to the electronic device 200 only when their frequency domain resources change. Thus, the electronic device 200 can know the frequency domain resources of the user equipment and the frequency domain resources of other electronic devices.

[0080] As described above, the interference determination unit 220 can determine whether the uplink signal from the user equipment to the electronic device 200 generates interference to other satellite devices based on the spatial radiation parameters of the user equipment (optionally, it can also include the ephemeris information of other electronic devices and / or the frequency domain resources of the user equipment and the frequency domain resources of other electronic devices). The strategy determination unit 240 according to an embodiment of the present disclosure will be described below.

[0081] According to an embodiment of the present disclosure, the strategy determination unit 240 is used to determine an interference coordination strategy for the user equipment to adjust the beam or for other electronic devices to adjust frequency domain resources when an uplink signal from the user equipment interferes with other electronic devices. Here, the interference coordination strategy includes two strategies: enabling the user equipment to adjust the beam; and enabling other electronic devices to adjust frequency domain resources.

[0082] According to an embodiment of the present disclosure, the electronic device 200 may receive the beamforming capability of the user equipment from the user equipment through the communication unit 210. Here, the beamforming capability parameter of the user equipment can indicate whether the user equipment can adjust the beam. For example, the beamforming capability can be represented by 1 bit of information. According to an embodiment of the present disclosure, the user equipment may report the beamforming capability parameter when reporting the spatial radiation parameter. Optionally, the user equipment may also report the beamforming capability parameter when accessing the network.

[0083] According to an embodiment of the present disclosure, the strategy determination unit 240 may determine the interference coordination strategy according to the beamforming capability of the user equipment. Specifically, when the beamforming capability of the user equipment indicates that the user equipment is capable of adjusting the beam, the strategy determination unit 240 may determine the interference coordination strategy as a strategy for enabling the user equipment to adjust the beam; when the beamforming capability of the user equipment indicates that the user equipment is unable to adjust the beam, the strategy determination unit 240 may determine the interference coordination strategy as a strategy for enabling other electronic devices to adjust frequency domain resources.

[0084] According to the embodiments of the present disclosure, Figure 2 As shown, the electronic device 200 may further include a generating unit 250 for generating beam adjustment indication information for the user equipment to adjust the beam when an uplink signal from the user equipment generates interference to other electronic devices and the beamforming capability of the user equipment indicates that the user equipment is capable of adjusting the beam.

[0085] According to an embodiment of the present disclosure, the beam adjustment indication information generated by the generation unit 250 may include time information of the beam adjustment, for example, including the start time and the end time of the beam adjustment. That is, the user equipment may determine to adjust the beam during the period from the start time to the end time according to the beam adjustment indication information. Optionally, the time information of the beam adjustment may also include the start time and the duration of the beam adjustment. That is, the user equipment may determine to adjust the beam during the duration starting from the start time according to the beam adjustment indication information.

[0086] According to an embodiment of the present disclosure, the beam adjustment indication information generated by the generation unit 250 may also include adjusted beam information, for example, TCI (Transmission Configuration Indication) may be used to indicate the adjusted beam information. That is, the electronic device 200 may configure an adjusted beam for the user equipment, and the adjusted beam may avoid interference with other satellite devices. In this way, the user equipment may determine the adjusted beam information according to the beam adjustment indication information, so as to adjust to the new beam within the time indicated by the beam adjustment indication information, thereby avoiding interference with other satellite devices.

[0087] According to an embodiment of the present disclosure, the beam adjustment indication information generated by the generation unit 250 may also include ephemeris information of other electronic devices subject to interference. That is, the user equipment may determine the adjusted beam information according to the ephemeris information of other electronic devices subject to interference, and the adjusted beam may avoid interference to other satellite devices. In this way, the user equipment may adjust to a new beam within the time indicated by the beam adjustment indication information, thereby avoiding interference to other satellite devices.

[0088] As described above, when the beamforming capability of the user equipment indicates that the user equipment can dynamically adjust the beam, that is, has the ability to adjust the beam, the strategy determination unit 240 can determine a strategy for the user equipment to adjust the beam to avoid or eliminate interference with other satellite devices.

[0089] Figure 3 is a signaling flow chart showing an interference coordination process according to an embodiment of the present disclosure. Figure 3 In the embodiment, the serving gNB may be implemented by the electronic device 200. Figure 3As shown, in step S301, the serving gNB of the UE and other gNBs can periodically exchange ephemeris information. Optionally, the serving gNB and other gNBs can also exchange frequency domain resource information used by them. In step S302, the UE reports spatial radiation parameters to the serving gNB. Optionally, the UE can also report the beamforming capability of the UE to the serving gNB. In step S303, the serving gNB determines whether the uplink signal from the UE to the serving gNB will cause interference to other gNBs based on the spatial radiation parameters of the UE. Next, in step S304, the serving gNB determines the interference coordination strategy. Here, it is assumed that the interference coordination strategy determined by the serving gNB is to enable the UE to adjust the beam. Next, in step S305, the serving gNB sends beam adjustment indication information to the UE. Next, in step S306, the UE adjusts the beam according to the beam adjustment indication information. Thus, the interference coordination strategy of the UE adjusting the beam avoids the interference of the uplink signal from the UE to the serving gNB to other gNBs.

[0090] According to the embodiments of the present disclosure, Figure 2 As shown, the electronic device 200 may also include a generating unit 260 for generating frequency domain resource adjustment request information for other electronic devices to adjust frequency domain resources when an uplink signal from the user equipment generates interference to other electronic devices and the beamforming capability of the user equipment indicates that the user equipment cannot adjust the beam.

[0091] According to an embodiment of the present disclosure, the frequency domain resource adjustment request information generated by the generation unit 260 may include the frequency domain resource information of other electronic devices being interfered with. In this way, other electronic devices can know the interfered frequency domain resources, and thus determine the adjusted frequency domain resources by themselves. Optionally, the frequency domain resource adjustment request information generated by the generation unit 260 may also include the adjusted frequency domain resource information. In other words, the electronic device 200 can recommend the adjusted frequency domain resources to other electronic devices. In this way, other electronic devices can adjust the frequency domain resources according to the adjusted frequency domain resources included in the frequency domain resource adjustment request information.

[0092] According to an embodiment of the present disclosure, the electronic device 200 may also receive frequency domain resource adjustment response information from other electronic devices through the communication unit 210. Here, in the case where the frequency domain resource adjustment request information includes the adjusted frequency domain resources, if other electronic devices agree to use the adjusted frequency domain resources included in the frequency domain resource adjustment request information, the frequency domain resource adjustment response information may include confirmation information, which indicates that other electronic devices agree to use the adjusted frequency domain resources included in the frequency domain resource adjustment request information.

[0093] As described above, the manner in which the electronic device 200 coordinates frequency domain resources with other electronic devices is described in a non-limiting manner. In this process, since the electronic device 200 and other electronic devices are satellite devices, communication between satellites will consume a lot of resources and time, and when satellites communicate with each other, interference with other satellite links or satellite-earth links must be avoided.

[0094] According to an embodiment of the present disclosure, in the process of the electronic device 200 coordinating frequency domain resources with other electronic devices, a narrow directional beam can be used to track other electronic devices, thereby sending frequency domain resource adjustment request information and / or frequency domain resource adjustment response information. Optionally, channels carrying other information other than the frequency domain resource adjustment request information and the frequency domain resource adjustment response information can also be multiplexed to send frequency domain resource adjustment request information and / or frequency domain resource adjustment response information. In the case of multiplexing other channels, the information sent can be set to a high priority and / or the information sent can be set to a high power to ensure the reliability of the communication between the electronic device 200 and other electronic devices. Optionally, a dedicated channel reserved specifically for frequency domain resource adjustment request information and / or frequency domain resource adjustment response information can also be used to send frequency domain resource adjustment request information and / or frequency domain resource adjustment response information. Thus, directional beams, multiplexed channels or dedicated channels can be used to transmit frequency domain resource adjustment request information and / or frequency domain resource adjustment response information to ensure the reliability of the frequency domain coordination process between the electronic device 200 and other electronic devices.

Figure 4As shown, in step S401, the serving gNB of the UE and other gNBs may periodically exchange ephemeris information. Optionally, the serving gNB and other gNBs may also exchange frequency domain resource information used by them. In step S402, the UE reports spatial radiation parameters to the serving gNB. Optionally, the UE may also report the beamforming capability of the UE to the serving gNB. In step S403, the serving gNB determines whether the uplink signal from the UE to the serving gNB will cause interference to other gNBs based on the spatial radiation parameters of the UE. Next, in step S404, the serving gNB determines the interference coordination strategy. Here, it is assumed that the interference coordination strategy determined by the serving gNB is to enable other gNBs to adjust frequency domain resources. Next, in step S405, the serving gNB sends frequency domain resource adjustment request information to other gNBs. Next, in step S406, other gNBs may determine whether to adjust the frequency domain resources used by them, and send frequency domain resource adjustment response information to the serving gNB. Therefore, the interference coordination strategy of adjusting frequency domain resources by other gNBs avoids interference of the uplink signal from UE to the serving gNB to other gNBs.

[0096] It can be seen that according to the electronic device 200 of the embodiment of the present disclosure, it is possible to determine whether the uplink signal from the user equipment interferes with other electronic devices based on the spatial radiation parameters of the user equipment. Further, the electronic device 200 can also formulate a reasonable interference coordination strategy, which may include a strategy for the user equipment to adjust the beam and a strategy for other electronic devices to adjust frequency domain resources. In this way, the interference of the uplink signal from the user equipment to the electronic device 200 providing services to it to other electronic devices can be eliminated or avoided.

The gNB 1600 includes one or more antennas 1610 and a base station device 1620. The base station device 1620 and each antenna 1610 can be connected to each other via an RF cable.

[0181] Each of the antennas 1610 includes a single or multiple antenna elements (such as multiple antenna elements included in a multiple-input multiple-output (MIMO) antenna) and is used for the base station device 1620 to transmit and receive wireless signals. Fig.16 As shown, gNB 1600 may include multiple antennas 1610. For example, multiple antennas 1610 may be compatible with multiple frequency bands used by gNB 1600. Fig.16 An example is shown in which the gNB 1600 includes multiple antennas 1610, but the gNB 1600 may also include a single antenna 1610.
