Description

Information processing method and related device

[0001] This application claims priority to the Chinese patent application filed with the China Patent Office on September 28, 2023, with application number 202311290494.7 and application name “Information Processing Methods and Related Devices”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the field of communication technology, and in particular to an information processing method and related devices. Background Art

[0003] With the development of communication technology, spectrum resources are being rapidly occupied and becoming increasingly scarce. To improve the utilization of spectrum resources, attempts have been made to adopt a spectrum resource co-construction and sharing mechanism, whereby multiple network devices can share the spectrum of the same frequency band. However, while the co-construction and sharing of spectrum resources between network devices can improve resource utilization, it also introduces various types of interference. For example, based on the signal direction, it can be divided into uplink interference and downlink interference; based on the interference scenario, it can be divided into interference between terrestrial networks, interference between terrestrial networks and non-terrestrial networks (NTNs), and interference between non-terrestrial networks, etc. Therefore, how to solve interference is an urgent problem that needs to be solved.

[0010] In an optional embodiment, the terminal information also includes frequency domain configuration information of uplink transmission of at least one second network device.

[0076] An embodiment of the present application provides an information processing method and related apparatus, in which a first network device receives terminal information of at least one second network device, the terminal information including the number of terminals served by the at least one second network device, location information of the at least one terminal served by the second network device, and equivalent isotropic radiated power information; the first network device determines, based on the terminal information, the total uplink interference generated by the terminals served by the at least one second network device on the first network device, thereby facilitating the first network device to perform corresponding interference coordination based on the total uplink interference.

[0077] Optionally, the embodiments of the present application can be applied to communication systems of various radio access technologies (RAT), for example, narrowband Internet of Things (NB-IoT) systems, long term evolution (LTE) communication systems, 5G (or new radio (NR)) communication systems, or transition systems between LTE communication systems and 5G communication systems, which may also be called 4.5G communication systems, and of course future communication systems, such as sixth generation (6G) or even seventh generation (7G) systems. The embodiments of the present application can also be applied to non-terrestrial networks (NTN), vehicle to everything (V2X), long term evolution-vehicle (LTE-V), vehicle to vehicle (V2V), machine type communications (MTC), Internet of Things (IoT), long term evolution-machine to machine (LTE-machine to machine, LTE-M), machine to machine (M2M), or future mobile communication systems.

[0078] Optionally, the NTN system may include a satellite system. According to the satellite altitude, that is, the satellite orbit height, the satellite system is divided into highly elliptical orbiting (HEO) satellites, geosynchronous orbit (GEO) satellites, medium earth orbit (MEO) satellites and low-earth orbit (LEO) satellites. In addition, the NTN system may also include high altitude platform station (HAPS) communication systems. Compared with communication infrastructure such as terrestrial cellular networks and submarine optical fiber cables, NTN has significant cost advantages. The research and development and manufacturing costs of modern small satellites are low, and software-defined technology can further extend the service life of in-orbit satellites. A large number of satellites are deployed in low-Earth orbit, and the round-trip transmission delay of data between satellites and ground terminals is greatly reduced to a low delay of tens of milliseconds. The use of technologies such as high frequency bands, multi-spot beams and frequency reuse has significantly improved the communication capabilities of satellites, reduced the unit bandwidth cost, and can meet the needs of high information rate services. NTN networks can be used in scenarios such as global coverage (such as remote areas and ocean-going ships), emergency relief (such as disaster monitoring and emergency communications), the Internet of Everything, and high-speed mobility (such as high-speed rail and airplanes).

[0079] Optionally, the network device is an access network (AN) device, such as a base station, that the terminal uses to access the mobile communication system wirelessly. The network device may also refer to a device that communicates with the terminal device over an air interface. The network device may include an evolved NodeB (eNodeB or eNB) transmission reception point (TRP) in a long term evolution (LTE) system or long term evolution-advanced (LTE-A), a next generation NodeB (gNB) in a fifth generation (5G) mobile communication system, an access network device in an open radio access network (O-RAN or open RAN), a next generation base station in a sixth generation (6G) mobile communication system, or a base station in a future mobile communication system, or an access node in a wireless fidelity (WiFi) system, etc.; or, the network device may be a relay station, a vehicle-mounted device, a future evolved public land mobile network (PLMN) device, a device in a device-to-device (D2D) network, a device in an M2M network, a device in an IoT network, or a network device in a public land mobile network (PLMN), etc.

[0080] Optionally, taking a base station as an example of a network device, the base station can communicate with the terminal device, or communicate with the terminal device through a relay station. The terminal can communicate with multiple base stations in different access technologies. The network device can be a module or unit that completes part of the functions of the base station, for example, it can be a centralized unit (CU), a distributed unit (DU), a centralized unit control plane (CU control plane, CU-CP) module, or a centralized unit user plane (CU user plane, CU-UP) module. Multiple DUs can be centrally controlled by one CU. CU and DU can be divided according to the protocol layer functions of the wireless network they possess, for example, the functions of the packet data convergence protocol (PDCP) layer and above protocol layers are set in the CU, and the functions of the protocol layers below the PDCP, such as the radio link control (RLC) layer and the medium access control (MAC) layer, are set in the DU. It should be noted that this division of the protocol layer is only an example, and it can also be divided at other protocol layers. The radio frequency device can be remote and not placed in the DU, or it can be integrated in the DU, or partly remote and partly integrated in the DU, and the embodiments of the present application do not impose any restrictions. In addition, in some embodiments, the control plane (CP) and user plane (UP) of the CU can also be separated and divided into different entities for implementation, namely the control plane CU entity (CU-CP entity) and the user plane CU entity (CU-UP entity). In this network architecture, the signaling generated by the CU can be sent to the terminal device through the DU, or the signaling generated by the terminal device can be sent to the CU through the DU. The DU can directly encapsulate the signaling through the protocol layer and pass it to the terminal device or CU without parsing it. In this network architecture, the CU is divided into a network device on the radio access network (RAN) side. In addition, the CU can also be divided as a network device on the core network (CN) side, and this application does not impose any restrictions on this. Optionally, the access network device can be a server, etc. For example, the network device in the vehicle V2X technology can be a road side unit (RSU). Optionally, the network device may also be various devices constituting an access node, such as an active antenna unit (AAU), a baseband unit (BBU), and the like.

[0081] Optionally, the network device is a network device in the NTN system and can be deployed on a high-altitude platform or satellite, such as a satellite or satellite base station. Scenarios in which the NTN system provides access to terminals may include transparent payloads and regenerative payloads. Transparent payloads are payloads that change the frequency carrier of the uplink RF signal and filter and amplify it before downlink transmission. This payload only has an RF processing unit and does not have baseband demodulation, decoding, or other processing. Therefore, the signal waveform is unchanged and is repeated. Regenerative payloads are payloads that transform and amplify the uplink RF signal before downlink transmission. Signal transformation refers to digital processing, which may include demodulation, decoding, recoding, remodulation, and / or filtering, which is equivalent to having all or part of the base station functions (such as gNB) on a satellite (or unmanned aircraft system platform (UAS platform)).

[0082] Figure 1 illustrates a transparent payload-based NTN scenario. As shown in Figure 1, there are one or more gateways connecting the NTN network and the public data network. The feeder link is the wireless link between the gateway and the satellite (or UAS platform). The service link is the wireless link between the terminal and the satellite (or UAS platform). The satellite (or UAS platform) can implement transparent payloads.

[0083] Figure 2 is a schematic diagram of a regenerative payload-based NTN scenario. As shown in Figure 2, the NTN scenario also includes a feeder link and a service link. Whether there is an inter-satellite link (ISL) between the satellites shown in Figure 2 is optional. If there is no ISL, the satellite must have a feeder link (mandatory if no ISL). The inter-satellite link requires the satellite to be a regenerative payload (i.e., if there is an inter-satellite link, the satellite is a regenerative payload). The ISL can operate in radio frequency or optical bands. User equipment (UE) is served by satellites (or UAS platforms) within a target service area. The target service area is the geographic area that the satellite can provide service.

[0084] Satellite communications operate in the microwave band, which has a frequency range of 1 GHz to 40 GHz. Table 1 shows the satellite spectrum and its main uses. This frequency range can be divided into the following categories: L, S, C, X, Ku, K, and Ka. Each band has different uses. The K band, which covers a frequency range of 18 GHz to 27 GHz, is not suitable for satellite communications because it falls within the frequency window most affected by atmospheric absorption losses. Therefore, the commonly used satellite communication bands are: L, S, C, X, Ku, and Ka. The L and S bands are used for mobile satellite communications. The C band has a relatively low frequency, wide signal coverage, and is less susceptible to weather. It is commonly used for applications such as fixed satellite services and is nearing saturation. The X band is a regulated band primarily used for fixed satellite services. The Ku band has a relatively high frequency and is susceptible to antenna interference, causing signal fluctuations. However, its signal strength is higher than that of the C band. Therefore, ground receiving antennas can be much smaller, typically as small as 0.35 meters in diameter, making it suitable for direct-to-home satellite broadcasts. The Ka band has been recently introduced. Because the C and Ku bands are near saturation and cannot carry more services, the search for higher-frequency Ka bands has begun. Higher-frequency bands offer more bandwidth and can support greater service capacity. With the rapid development of satellite communications, the Ku / Ka / Q / V bands have become popular for satellite communications applications, and spectrum resources are rapidly being occupied and becoming increasingly scarce. The Q band ranges from 30-50 GHz, and the V band from 50-75 GHz.

[0090] Optionally, the network device may be a macro base station (also known as a large station), a micro base station or an indoor station (also known as a small station), or a relay node or a donor node. This application does not limit the specific technology and specific device form adopted by the access network device. Optionally, the communication device used to implement the function of the network device may be a network device, or a device that can support the network device to implement the function, such as a chip system, which may be installed in the network device.

[0091] Optionally, a terminal, also known as a terminal device (terminal), user equipment (UE), mobile station (MS), mobile terminal (MT), etc., is a device with wireless transceiver functions that can send signals to network devices or receive signals from network devices. Terminal devices may include user equipment (UE), sometimes also called terminal, access station, UE station, remote station, wireless communication equipment, or user device, etc. The terminal device is used to connect people, objects, machines, etc., and can be widely used in various scenarios, such as but not limited to the following scenarios: cellular communication, D2D, V2X, M2M / MTC, IoT, virtual reality (VR), augmented reality (AR), industrial control, self driving, remote medical, smart grid, smart furniture, smart office, smart wear, smart transportation, smart city, drones, robots and other scenarios. For example, the terminal can be a mobile phone, a tablet computer, a computer with wireless transceiver functions, a VR terminal, an AR terminal, a wireless terminal in industrial control, a wireless terminal in unmanned driving, a smart speaker in an IoT network, a wireless terminal device in telemedicine, a wireless terminal device in a smart grid, 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. As an example and not a limitation, the terminal can also be a wearable device, which can also be called a wearable smart device or a smart wearable device, etc., which is a general term for wearable devices that are intelligently designed and developed using wearable technology for daily wear, such as glasses, gloves, watches, clothing, and shoes. The various terminals described above, if located on a vehicle (for example, placed in or installed in a vehicle), can be considered as vehicle-mounted terminal devices, which are also called on-board units (OBUs). The terminal can also be a vehicle-mounted module, vehicle-mounted module, vehicle-mounted component, vehicle-mounted chip or vehicle-mounted unit that is built into the vehicle as one or more components or units. The vehicle can implement the method described in the embodiments of the present application through the built-in vehicle-mounted module, vehicle-mounted module, vehicle-mounted component, vehicle-mounted chip or vehicle-mounted unit.

[0092] The network equipment and / or terminal equipment can be fixed or movable. The network equipment and / or terminal equipment can be deployed on land, including indoors or outdoors, handheld or vehicle-mounted; or can be deployed on the water surface; or can be deployed on aircraft, balloons and artificial satellites in the air. This application does not limit the environment / scenario in which the network equipment and terminal equipment are located. The network equipment and terminal equipment can be deployed in the same or different environments / scenarios, for example, the network equipment and terminal equipment are deployed on land at the same time; or, the network equipment is deployed on land and the terminal equipment is deployed on water surface, etc., and no further examples are given.

[0093] The information transmission method provided in this application can be applied to the communication system shown in Figure 3. The number of network devices and terminals shown in Figure 3 is used as an example, but this application does not limit the number of network devices and terminals. In Figure 3, the network devices are satellite 110a, macro base station 110b, and micro base station or indoor station 110c; the terminals are mobile phone 120a accessing the network through macro base station 110b, vehicle 120b accessing the network through satellite 110a, airplane 120c accessing the network through satellite 110a, mobile phone 120d accessing the network through satellite 110a, printer 120e, mobile phone 120f, and computer 120g accessing the network through micro base station or indoor station 110c. Optionally, mobile phone 120d and satellite 110a can communicate with each other by using airplane 120c as a relay. Mobile phone 120f and micro base station or indoor station 110c can communicate with each other by using computer 120g as a relay.

[0094] Interference between different network devices can be divided into downlink interference and uplink interference based on signal direction. Downlink interference is characterized by fewer interference sources and higher interference intensity. The source of interference to mobile phone 120a is satellite 110a. If satellite 110a covers mobile phone 120a, but other satellites do not, the interference from other satellites to mobile phone 120a primarily comes from the sidelobes of the transmit beam, resulting in greater path loss and lower interference levels. Therefore, the primary source of interference to mobile phone 120a is satellite 110a. Since low-orbit satellites are closer to ground terminals, if satellite 110a is a low-orbit satellite, the interference intensity from satellite 110a to mobile phone 120a is also higher. For example, Figure 4 is a schematic diagram of a low-orbit satellite interfering with a ground terminal. A ground terminal refers to a terminal that communicates through a ground network. As shown in Figure 4, the terminal is a ground terminal, and the interference sources interfering with Terminal 1 are Satellite 1 and Satellite 2. Both Satellite 1 and Satellite 2 are low-orbit satellites. Satellite 1 covers Terminal 1, and the interference from Satellite 2 to Terminal 1 mainly comes from the sidelobes of the transmitted beam. Therefore, the path loss is large and the interference level is low. Therefore, Satellite 1 is the main interference source for Terminal 1.

[0095] Uplink interference has characteristics such as multiple interference sources, strong aggregate interference, and beam-level interference. The sources of interference to satellite 110a can be all ground terminals within the coverage or visual range of satellite 110a. In particular, ground terminals located near the main lobe of the low-orbit satellite are the main interference sources, and the aggregate interference from these ground terminals to the low-orbit satellite is strong. In the scenario where the low-orbit satellite is multi-beam, the interference to the low-orbit satellite has beam-level characteristics, that is, different beam directions experience different interference. For example, Figure 5 is another schematic diagram of ground terminal interference with a low-orbit satellite. The sources of interference to the low-orbit satellite can be all ground terminals within the coverage or visual range of the low-orbit satellite, except for the terminals it serves. As shown in Figure 5, the dotted lines represent the interference signals from the ground terminals to the satellite. All ground terminals within the coverage or visual range of the satellite will interfere with the satellite. As shown in Figure 5, the coverage range of the satellite is the geographical area that the satellite can provide service, and the visual range of the satellite is the geographical area within the tangent range of the satellite and the earth's surface. The visual range of the satellite is generally larger than the coverage range of the satellite.

[0096] Interference between different network devices can be divided into satellite-to-ground interference (such as the interference between satellite 110a and base station 110b in Figure 3) and high-orbit interference (such as the interference between satellite 110a and a high-orbit satellite in Figure 3, if satellite 110a is a low-orbit satellite). In satellite-to-ground interference, due to the large number of base stations and terminals in terrestrial cellular networks and the fact that LEO satellites are closer to the ground and have less path loss, interference is more likely to occur between LEO satellites and terrestrial cellular networks. For example, Figure 6 is a schematic diagram of a satellite-to-ground interference scenario. As shown in Figure 6, solid lines represent valid signals, dashed lines represent interfering signals, and arrows indicate signal directions. The satellite-to-ground interference classification shown in Figure 6 is shown in Table 4. Cellular base stations and cellular terminals will experience interference from LEO satellites due to satellite power leakage. In addition, cellular base stations will also experience interference from LEO satellite terminals due to power leakage from LEO satellite terminals. Because LEO satellites are closer to the ground, they are subject to interference caused by power leakage from cellular base stations and cellular terminals. LEO satellite terminals may also be interfered with by cellular base stations due to power leakage from the cellular base stations.

[0097] Table 4 Classification of satellite-to-ground interference

[0098] In high-orbit and low-orbit interference, high-orbit satellites have a large coverage area, and the coverage of low-orbit satellites will overlap with the coverage of high-orbit satellites. Since low-orbit satellites have smaller path loss, interference is more likely to occur between high-orbit and low-orbit satellites. For example, Figure 7 is a schematic diagram of an interference scenario between a low-orbit satellite and a high-orbit satellite, as shown in Figure 7, where the solid line segment represents the valid signal, the dotted line segment represents the interference signal, and the arrow represents the signal direction. The high-orbit and low-orbit interference classification shown in Figure 7 is shown in Table 5. LEO satellites will be interfered with by GEO satellite terminals due to power leakage, GEO satellites will be interfered with by LEO satellite terminals due to power leakage, LEO satellite terminals will be interfered with by GEO satellite terminals due to power leakage, and GEO satellite terminals will be interfered with by LEO satellite terminals due to power leakage.

[0100] The information processing method provided in the embodiments of the present application can analyze the total uplink interference generated by the uplink transmission of terminals served by one or more network devices on the uplink reception of other network devices in the above-mentioned interference scenario. This facilitates the assessment of uplink interference based on the total uplink interference, reduces uplink interference through interference coordination, enables co-frequency coexistence between network devices, and improves spectrum utilization. The embodiments of the present application are described below with reference to the accompanying drawings.

[0101] Please refer to FIG8 , which is a flow chart of an information processing method provided in an embodiment of the present application. The information processing method shown in FIG8 is described using the interaction between a first network device and at least one second network device as an example. As shown in FIG8 , the information processing method may include but is not limited to the following steps:

[0102] S101 at least one second network device sends terminal information, accordingly, the first network device receives the terminal information, the terminal information sent by the second network device or from the second network device includes the number of terminals served by the second network device, the location information of the terminal serving, and EIRP information;

[0103] In an optional embodiment, the terminal information includes the number of terminals served by at least one second network device, location information of the served terminals, and equivalent isotropic radiated power (EIRP) information. Optionally, multiple second network devices send the terminal information to one of the second network devices, and the second network device forwards the terminal information of the multiple second network devices to the first network device.

[0104] In another optional implementation, the terminal information includes the number of terminals served by the second network device, location information of the served terminals, and EIRP information. Optionally, multiple second network devices may respectively send their own terminal information to the first network device.

[0105] Optionally, if the first network device is a mobile network device, such as a satellite, the first network device also needs to send its own location information to at least one second network device, so that the second network device can determine the EIRP information of the terminal served by the second network device based on the location information. The location information may include parameters such as longitude, latitude, altitude and speed, and may also include motion trajectory parameters, such as orbital parameters. The EIRP information may include the average antenna gain of the user served by the second network device, and also include the average transmit power or statistical information of the transmit power of the terminal served by the second network device. Optionally, the statistical information of the transmit power of the terminal served by the second network device may be a cumulative distribution function (CDF) curve of the transmit power. Due to uplink power control, the transmit power of the terminal changes dynamically, and the CDF curve of the transmit power is a statistic of the transmit power of the terminal over a period of time.

[0106] Optionally, the number of terminals served by the second network device and the EIRP information of the served terminals may also be referred to as the connection terminal information of the second network device. The location information of the second network device or the geographical area served may be equivalent to the location information of the terminals served by the second network device.

[0107] Optionally, one or more second network devices may send the terminal information periodically or in an event-triggered manner.

[0108] S102. The first network device determines, based on the terminal information, a total uplink interference caused by at least one terminal served by the second network device to the first network device.

[0109] In an optional implementation, the terminal information also includes frequency domain configuration information for uplink transmission of at least one second network device. The frequency domain configuration information for uplink transmission of the second network device is the frequency domain configuration information for uplink transmission of the terminal served by the second network device for uplink scheduling, and may also be referred to as frequency domain configuration information or frequency domain resource information for uplink scheduling of the second network device. Optionally, the frequency domain configuration information for uplink transmission or uplink scheduling may include the frequency range or bandwidth occupied by the uplink transmission or uplink scheduling. Accordingly, step S102 may include: the first network device determines the antenna receiving gain based on the location information of the terminal served by the second network device; and determines the uplink interference caused by the terminal served by the second network device to the first network device based on the EIRP information of the terminal served by the second network device, the antenna receiving gain, and the frequency domain configuration information for uplink transmission of the second network device. Accordingly, the first network device may use this method to determine the uplink interference caused by other terminals served by the second network device to the first network device.

[0110] In step S102, the first network device determines the total uplink interference generated by a terminal served by the second network device on the first network device. The total uplink interference is the uplink interference generated by a terminal served by the second network device on the first network device. In step S102, the first network device determines the total uplink interference generated by multiple terminals served by the second network devices on the first network device. The total uplink interference is obtained by summing the uplink interference generated by the multiple terminals served by the second network devices on the first network device.

[0111] In an optional embodiment, the uplink interference generated by the terminal served by the second network device on the first network device is the interference-to-noise ratio (INR) generated by the terminal served by the second network device on the first network device. In this way, the first network device determines the INR generated by the terminal served by the second network device on the first network device based on the EIRP information of the terminal served by the second network device, the antenna reception gain G, and the frequency domain configuration information of the uplink transmission of the second network device, including: the first network device determines the EIRP based on the EIRP information of the user served by the second network device; determines the ratio G / T between the antenna reception gain G and the noise temperature T based on the location information of the terminal served by the second network device and the antenna reception gain G; determines the free space path loss PL based on the location information of the terminal served by the second network device. FS ; According to the loss model, determine other path losses PL other , such as atmospheric loss, scintillation loss, human body loss, polarization loss, shadow fading, rain attenuation, etc.; according to the frequency domain configuration information of the uplink transmission of the second network device, the bandwidth B is determined; then, the first network device determines the bandwidth B according to the EIRP, the ratio G / T between the antenna receiving gain G and the noise temperature T, and the free space path loss PLFS , other losses PL other , bandwidth B determines the INR generated by the terminal served by the second network device to the first network device.

[0112] Optionally, the first network device can be configured to generate a signal based on EIRP, G / T ratio, and PL. FS PL other B. Determine the INR generated by the terminal served by the second network device to the first network device. The formula can be used to obtain the INR: INR [dB] = EIRP [dBW] + G / T [dB / K] - k [dBW / K / Hz] - PL FS [dB]-PL other [dB]-B[dBHz] (1)

[0113] Where k is the Boltzmann constant, e.g., -228.6. [dB] represents the decibel, [dBW] represents the absolute value of power, based on 1 watt (W), where dBW = 10log(P / 1W), where P represents power. K represents the noise temperature in kelvins (K). [dBHz] represents the bandwidth (B) in decibel-hertz (Hz).

[0114] Correspondingly, the total uplink interference generated by the terminal served by at least one second network device on the first network device is the ratio I / N of the uplink aggregate interference I to the noise N, which is obtained by summing the INR generated by the terminal served by at least one second network device on the first network device.

[0115] In one optional embodiment, the first network device performs statistics on multiple I / N ratios determined within a statistical period to obtain a CDF curve for the total uplink interference I / N. The first network device may determine the total uplink interference generated by at least one terminal served by the second network device on the first network device based on the CDF curve for the total uplink interference I / N. The period during which the second network device transmits terminal information is less than the statistical period for the first network device to calculate the determined I / N ratio. The CDF curve for the total uplink interference I / N may represent the percentage of I / N ratios in different situations within the statistical period. For example, the I / N ratio corresponding to 20% of the time within the statistical period is no greater than -X1 [dB]; the I / N ratio corresponding to 0.03% of the time within the statistical period is no greater than -X2 [dB]; the I / N ratio corresponding to 0.005% of the time within the statistical period is no greater than -X3 [dB]; and the I / N ratio corresponding to 100% of the time within the statistical period is no greater than -X3 [dB]. X1 through X3 are positive numbers.

[0116] Optionally, the CDF curve of the uplink total interference I / N can not only represent the percentage of different I / N ratios within the statistical period, but also reflect that for a certain proportion of time within the statistical period, the corresponding I / N ratio is not greater than a certain value [dB], and the resulting bit error rate (BER) does not exceed a certain proportion. For example, for more than 20% of the time within the statistical period, the resulting BER does not exceed the first proportion, and the corresponding I / N ratio is not greater than -X1 [dB]. For 0.03% of the time within the statistical period, the resulting BER does not exceed the second proportion, and the corresponding I / N ratio is not greater than -X2 [dB]. For 0.005% of the time within the statistical period, the resulting BER does not exceed the third proportion, and the corresponding I / N ratio is not greater than -X3 [dB]. For 100% of the time within the statistical period, the resulting BER does not exceed the third proportion, and the corresponding I / N ratio is not greater than -X3 [dB]. Where X1 to X3 are greater than or equal to 0.

[0117] In another optional embodiment, the uplink interference generated by a terminal served by the second network device on the first network device is the interference power generated by the terminal served by the second network device on the first network device. Accordingly, the total uplink interference is the sum of the interference power generated by at least one terminal served by the second network device on the first network device.

[0118] In an optional implementation, after step S102, the information transmission method shown in FIG8 further includes the following steps:

[0119] S103. The first network device determines whether to perform interference coordination based on the total uplink interference generated by at least one terminal served by the second network device on the first network device.

[0120] In an optional implementation, taking the uplink total interference ratio (I / N) as an example, step S103 includes: if the I / N ratio calculated by the first network device is greater than an interference threshold, determining to perform interference coordination; and if the I / N ratio calculated by the first network device is less than or equal to the interference threshold, determining not to perform interference coordination. Optionally, the interference threshold is the interference threshold of the communication system in which the first network device is located, as specified by the International Telecommunication Union (ITU). The interference threshold may also be referred to as an interference protection threshold, a protection threshold, or the like.

[0121] In another optional implementation, taking the uplink total interference ratio (I / N) as an example, step S103 includes: the first network device determining whether to perform interference coordination based on a CDF curve of the uplink total interference ratio (I / N). Alternatively, the interference threshold specified by the ITU, represented by a CDF curve, is referred to as a CDF curve of the interference threshold I / N. The first network device determines whether to perform interference coordination based on the CDF curve of the uplink total interference ratio (I / N) and the CDF curve of the interference threshold I / N.

[0122] The CDF curve of the interference threshold I / N represents the interference threshold I / N corresponding to the time period exceeding a certain percentage within the statistical period that should not cause the bit error rate (BER) to exceed a certain percentage. For example, but not limited to, within the statistical period, the time period exceeding a first percentage should not cause the BER to exceed a first value, and the corresponding interference threshold I / N is -T1 [dB]. Within the statistical period, the time period exceeding a second percentage should not cause the BER to exceed a second value, and the corresponding interference threshold I / N is -T2 [dB]. Within the statistical period, the time period exceeding a third percentage should not cause the BER to exceed a third value, and the corresponding interference threshold I / N is -T3 [dB]. Wherein, T1 to T3 are greater than or equal to 0. For example, on the CDF curve of the uplink total interference I / N, the time period exceeding a first percentage should not cause the BER to exceed the uplink total interference I / N corresponding to the first value, and the time period exceeding a first percentage on the CDF curve of the interference threshold I / N should not cause the BER to exceed the interference threshold I / N corresponding to the first value. The time on the CDF curve of the uplink total interference I / N exceeding the first proportion should not cause the BER to exceed the uplink total interference I / N corresponding to the first value, which is less than or equal to -T1 [dB]. The time on the CDF curve of the uplink total interference I / N exceeding the second proportion should not cause the BER to exceed the uplink total interference I / N corresponding to the second value, which is less than or equal to -T2 [dB]. The time on the CDF curve of the uplink total interference I / N exceeding the third proportion should not cause the BER to exceed the uplink total interference I / N corresponding to the third value, which is less than or equal to -T3 [dB].

[0123] In an optional implementation, taking the sum of the interference powers generated by terminals served by at least one second network device on the first network device as an example, step S103 includes: if the sum of the interference powers calculated by the first network device is greater than an interference threshold, determining to perform interference coordination; and if the sum of the interference powers calculated by the first network device is less than or equal to the interference threshold, determining not to perform interference coordination. Optionally, the interference threshold is provided by the ITU, determined by the first network device, or predefined.

[0124] In an optional implementation, the information transmission method shown in FIG8 further includes the following steps: if the first network device determines to perform interference coordination, step S104 is executed; if the first network device determines not to perform interference coordination, the process is terminated.

[0125] S104. The first network device performs interference coordination.

[0126] In an optional embodiment, step S104 includes: the first network device determines the first area based on the uplink interference generated by the terminals served by at least one second network device to the first network device; and determines the beam weight of the receiving beam, wherein the beam weight is used to determine the beam direction, the main lobe of the receiving beam points to other areas other than the first area, or the null direction of the receiving beam points to the first area.

[0127] Optionally, the interference intensity of uplink interference generated by terminals served by the second network device in the first area on the first network device is greater than a preset value. Taking the interference intensity of uplink interference as INR as an example, the first network device determining the first area may include: the first network device determining multiple areas based on the location information of terminals respectively served by at least one network device; the first network device may determine, from the multiple areas, one or more areas where the INR generated by terminals served by the second network device on the first network device is greater than a preset value as the first area. Optionally, the preset value is an empirical value, defined by a protocol, or determined by the first network device.

[0128] Optionally, the first area is an area where one or more second network devices are located, where the interference intensity of uplink interference generated by the served terminals on the first network device is greater than a preset value. Taking the interference intensity of uplink interference as INR as an example, the first network device determining the first area may include: the first network device determining one or more second network devices where the INR generated by the served terminals on the first network device is greater than a preset value; the first network device determining the area where the one or more second network devices are located, or the area where the terminals respectively served by the one or more second network devices are located as the first area.

[0129] In another optional embodiment, step S104 includes: the first network device configuring a frequency band for uplink transmission, wherein the frequency band for uplink transmission of the first network device does not overlap with the frequency band for uplink transmission of at least one second network device. For example, the frequency band for uplink transmission of the first network device and the frequency band for uplink transmission of the second network device are shown in FIG. 9 , and the two frequency bands do not overlap.

[0130] As can be seen, in the information processing method described in Figure 8, the first network device can determine the total uplink interference generated by one or more terminals served by the second network device by executing steps S101 and S102, thereby facilitating the execution of corresponding interference coordination based on the total uplink interference. Furthermore, the first network device can determine whether interference coordination is required by executing step S103. If interference coordination is determined to be required, the interference coordination including but not limited to the interference coordination described in step S104 above can be executed, thereby reducing the interference generated by the terminal served by the at least one second network device on the first network device. This is also conducive to the uplink co-frequency coexistence of the first network device and the at least one second network device or the communication system in which the at least one second network device is located, thereby improving spectrum utilization.

[0131] Please refer to Figure 10, which is a schematic diagram of another information processing method provided by an embodiment of the present application. Figure 10 takes the first network device as a satellite, the terminal served by the first network device as a satellite terminal, and the second network device as a network device within the coverage or visual range of the satellite, such as a cellular base station within the coverage or visual range of the satellite, and the terminal served by the second network device as a cellular terminal as an example. Since cellular terminals generally use omnidirectional antennas with fixed antenna transmission gain that does not change with angle, the satellite does not need to send its own ephemeris information to the cellular base station so that the cellular base station can determine the antenna transmission gain and EIRP information of the cellular terminal.

[0132] As shown in Figure 10, a cellular base station transmits terminal information to a satellite. This terminal information includes the number of cellular terminals served by the cellular base station, the location information of the cellular terminals served by the cellular base station, and EIRP information. Other cellular base stations within the satellite's coverage or visual range may also transmit terminal information to the satellite. The satellite receives the terminal information transmitted by the cellular base station and other cellular base stations and, based on the received terminal information, determines the total uplink interference caused to the satellite by the cellular terminals served by the cellular base station and other cellular base stations. Optionally, the satellite determines whether to perform interference coordination based on the total uplink interference. If interference coordination is determined to be performed, interference coordination is performed; if interference coordination is determined not to be performed, the process ends. The relevant contents of the information processing method shown in Figure 10, such as the contents of the terminal information and the optional implementation method of determining the total uplink interference caused to the satellite by the cellular terminals served by the cellular base station and other cellular base stations based on the received terminal information, can be found in the relevant contents of the information processing method described in Figure 8 and are not repeated here.

[0133] Optionally, in the information processing method shown in FIG10 , the location information of the cellular base station can be used as or equivalent to the location information of the cellular terminal served by the cellular base station and sent to the satellite, that is, the location information of the cellular terminal served by the cellular base station can be the location information of the cellular base station.

[0134] Taking the uplink interference generated by the terminal served by the cellular base station to the satellite as INR as an example, the satellite determines the INR generated by the cellular terminal served by the cellular base station to the satellite by referring to the above formula (1). In which, compared with the determination of G / T in the method described in Figure 8, in the method described in Figure 10, the satellite needs to be determined based on the location information of the cellular base station, the satellite's ephemeris information and the antenna pattern; compared with the free space path loss PL in the method described in Figure 8, FS In the embodiment of the present application, the satellite needs to be determined based on the location information of the cellular base station and other cellular base stations, as well as the satellite's ephemeris information.

[0135] Optionally, the method described in FIG10 uses the recommended interference threshold for satellite systems provided by the ITU, as opposed to the interference threshold used in the method described in FIG8 . If the satellite-calculated total uplink interference I / N is less than or equal to the recommended interference threshold, the satellite does not need to perform interference coordination and can co-exist with the terrestrial cellular system uplink. If the satellite-calculated total uplink interference I / N is greater than the recommended interference threshold, the satellite can co-exist with the terrestrial cellular system uplink but must perform interference coordination, or the satellite does not co-exist with the terrestrial cellular system uplink.

[0136] Optionally, in contrast to the CDF curve of the interference threshold I / N used in the method described in FIG8 , the method described in FIG10 uses the CDF curve of the interference threshold I / N of the satellite system provided by the ITU. For example, the ITU recommends that interference from fixed service systems, such as cellular base stations, to satellite systems be subject to the following restrictions: For example, taking an annual statistical period, the BER should not exceed 1×10 for more than 20% of the time in any month. -6 , the corresponding interference threshold I / N = -10dB; for more than 0.03% of the time in any month, the BER should not exceed 1×10 -4 , the corresponding interference threshold I / N = -2.4dB; for any month where more than 0.005% of the time should not cause the BER to exceed 1×10-3, the corresponding interference threshold I / N = 0dB; for any month where more than 100% of the time should not cause the BER to exceed 1×10-7, the corresponding interference threshold I / N = -12dB. Accordingly, the above-mentioned ITU-provided interference threshold limits can be expressed as the corresponding relationship between the percentage of the worst month and I / N (dB), as shown in Figure 11. The percentage of the worst month refers to the percentage of months corresponding to the interference threshold that do not cause the BER to exceed a certain value. Converting the corresponding relationship shown in Figure 11 into a CDF curve can be shown in Figure 12. Accordingly, the satellite determines whether to perform interference coordination based on the CDF curve of the uplink total interference I / N and the CDF curve of the interference threshold I / N.

[0137] In the method described in FIG10 , the optional implementation method of the satellite performing interference coordination can be found in the relevant description of step S104 in the above method and will not be described in detail here. For example, FIG13 shows a schematic diagram of beam weights, where each diamond-shaped area in FIG13 is a plurality of areas determined by the satellite based on the location information of the terminal served by each cellular base station. The satellite determines an area with an interference intensity greater than a preset value based on the uplink interference generated by the terminals served by the cellular base stations within each diamond-shaped area, such as the gray-filled area in FIG13 , as the first area. In this way, the main lobe of the satellite's receive beam is not directed toward the first area. For example, by adjusting the null direction of the receive beam to point toward the first area, the uplink interference generated by the cellular terminal's uplink transmission on the satellite's uplink reception can be reduced.

[0138] As can be seen, in the satellite-to-ground uplink interference scenario shown in Figure 10, the terrestrial cellular system is the interferer and the satellite system is the interfered party. After the cellular base station periodically reports terminal information related to itself to the satellite system, the satellite can calculate the total uplink interference based on the above terminal information. Based on the calculated total uplink interference, the satellite determines whether to perform interference coordination or whether to co-exist with the terrestrial cellular system uplink. Therefore, when the total uplink interference is less than or equal to the interference threshold, the terrestrial cellular system can co-exist with the satellite system uplink, thereby improving spectrum utilization. If the total uplink interference is greater than the interference threshold, the terrestrial cellular system cannot co-exist with the satellite system uplink, and the uplink interference of the terrestrial cellular system to the satellite system can be reduced through beam weight design.

[0139] In addition, the scenario considered in the embodiments of the present application is the interference caused by the uplink transmission of the cellular terminal to the uplink reception of the satellite, rather than the interference caused by the uplink transmission of the satellite gateway to the uplink reception of the cellular base station. For example, in the interference caused by the uplink transmission of the satellite gateway to the uplink reception of the cellular base station, the cellular base station receives the relevant information of the gateway. If applied to the analysis of the satellite-to-ground uplink interference scenario, it will greatly affect the accuracy of the interference analysis. In addition, the embodiments of the present application first analyze the interference situation and then perform the interference coordination operation, which also avoids the problem of low spectrum utilization caused by simply causing the cellular base station to avoid a certain frequency domain resource to reduce the uplink interference to the satellite.

[0140] Please refer to Figure 14, which is a schematic diagram of another information processing method provided by an embodiment of the present application. Figure 14 takes the first network device as a low-orbit satellite, the terminal served by the first network device as a low-orbit terminal, the second network device as a high-orbit satellite whose geographical area of ​​service is within the coverage or visual range of the low-orbit satellite, and the terminal served by the second network device as a high-orbit terminal as an example. The location information of the terminal served by the second network device is the location information of the geographical area served by the high-orbit satellite, and the terminal served by the second network device is the terminal served by the high-orbit satellite in this geographical area. Since the high-orbit terminal uses a non-omnidirectional antenna, the antenna transmission gain is not fixed, but varies with the angle, so the low-orbit satellite needs to send its own ephemeris information to the high-orbit satellite so that the high-orbit satellite can determine the antenna transmission gain and EIRP information of the high-orbit terminal.

[0141] The geographical area served by a high-orbit satellite refers to the geographical area covered by the high-orbit satellite's beam. If the high-orbit satellite adopts a beam hopping mechanism, the high-orbit satellite's N beams point to N geographical areas within the coverage area during the time period [t0, t1], and point to other N geographical areas within the coverage area during the time period [t1, t2] (which may be different from or the same as the N geographical areas pointed to during the time period [t0, t1]). The high-orbit satellite's beam scheduling information refers to the beam pointing (direction) information of the high-orbit satellite at different time periods within a period of time. The ephemeris information of a low-orbit satellite can be either orbit parameter ephemeris or position and velocity state vector ephemeris. The orbit parameter ephemeris includes parameters such as the satellite's semi-major axis, eccentricity, argument of periapsis, longitude of ascending node, inclination, and mean anomaly at the reference time (epoch time). The velocity state vector ephemeris includes the 3D position vector and 3D velocity vector of the satellite at the reference time.

[0142] In the information processing method shown in FIG14 , a low-orbit satellite transmits its ephemeris information to at least one high-orbit satellite. Based on the ephemeris information, the at least one high-orbit satellite determines the EIRP information of terminals served by the at least one high-orbit satellite in the geographic area served. The at least one high-orbit satellite transmits terminal information to the low-orbit satellite, which includes the location information of the geographic area served by the at least one high-orbit satellite and the number and EIRP information of cellular terminals served by the at least one high-orbit satellite in the geographic area. Based on the received terminal information, the low-orbit satellite determines the total uplink interference generated by the cellular terminals served by the at least one high-orbit satellite in the geographic area to the low-orbit satellite. Optionally, the low-orbit satellite determines whether to perform interference coordination based on the total uplink interference. If interference coordination is determined to be performed, interference coordination is performed; if interference coordination is determined not to be performed, the process terminates. Relevant content of the information processing method shown in FIG14 , such as the optional implementation method for the low-orbit satellite to determine the total uplink interference generated by the cellular terminals served by the high-orbit satellite in the geographic area to the low-orbit satellite, can be found in the relevant content of the information processing method described in FIG8 , and is not redundantly referenced here.

[0143] Optionally, in the information processing method shown in FIG14 , the location information of the geographic area served by the high-orbit satellite can be used as, or equivalently, the location information of the terminals served by the high-orbit satellite in the geographic area and sent to the low-orbit satellite. The location information of the geographic area served by the high-orbit satellite can be the beam scheduling information within [t1, t2]. The beam scheduling information is a two-dimensional matrix consisting of a time unit index and the beam index of the high-orbit satellite's scheduled beam, or a structure consisting of three elements: the time unit index, the beam normal direction of the high-orbit satellite's scheduled beam, and the beam coverage radius. The beam normal direction information of the high-orbit satellite's scheduled beam can include longitude and latitude, or can include azimuth and elevation. The average antenna gain of the terminals served by the high-orbit satellite in the geographic area served is determined based on the direction of the low-orbit satellite relative to the high-orbit satellite's scheduled beam. The frequency domain configuration information of the terminals served by the high-orbit satellite is associated with the high-orbit satellite's scheduled beam, and can also be referred to as being associated with the high-orbit satellite's beam scheduling information. The high-orbit satellite scheduling beam position is determined based on the beam position scheduling information of the high-orbit satellite. The beam position scheduling information can be found in the above description and will not be described in detail here. The frequency domain configuration information includes the frequency band, resource block (RB) or subcarrier occupied by the high-orbit satellite uplink scheduling (or uplink transmission).

[0144] Taking the uplink interference generated by the terminal in the geographical area served by the high-orbit satellite to the low-orbit satellite as INR as an example, the low-orbit satellite determines the INR generated by the terminal in the geographical area served by the high-orbit satellite to the low-orbit satellite, which can be referred to the above formula (1). In which, compared with the determination of G / T in the method described in Figure 8, in the method described in Figure 14, the low-orbit satellite needs to be determined based on the location information of the geographical area, the ephemeris information of the low-orbit satellite and the antenna pattern; compared with the free space path loss PL in the method described in Figure 8, FS In the method described in FIG14 , the low-orbit satellite needs to be determined based on the location information of the geographical area and the ephemeris information of the low-orbit satellite.

[0145] Optionally, the method described in FIG14 may also use the recommended interference threshold value for satellite systems provided by the ITU. If the total uplink interference I / N calculated by the LEO satellite is less than or equal to the recommended interference threshold value, the LEO satellite does not need to perform interference coordination, and the LEO satellite can coexist with the uplink system of the high-orbit satellite on the same frequency. If the total uplink interference I / N calculated by the LEO satellite is greater than the recommended interference threshold value, the LEO satellite can coexist with the uplink system of the high-orbit satellite on the same frequency, but interference coordination is required, or the LEO satellite does not coexist with the uplink system of the high-orbit satellite on the same frequency.

[0146] Optionally, the method described in FIG14 utilizes a CDF curve for the interference threshold I / N of a high-orbit satellite system as provided by the ITU, such as the ITU-recommended CDF curve for the interference I / N from other satellite service systems, such as terminals served by high-orbit satellites, into low-orbit satellite systems. Accordingly, the low-orbit satellite determines whether to perform interference coordination based on the CDF curve for the total uplink interference I / N and the CDF curve for the interference threshold I / N.

[0147] In the method described in FIG14 , the optional implementation method of the low-orbit satellite performing interference coordination can be found in the relevant description of step S104 in the above method. For example, FIG15 shows another schematic diagram of the beam weight, wherein each diamond area in FIG15 is a plurality of areas determined by the low-orbit satellite based on the position information of the high-orbit terminal served by the high-orbit satellite, and the low-orbit satellite determines the area where the interference intensity is greater than the preset value based on the uplink interference caused by the high-orbit terminal to the satellite in each diamond area, such as the gray-filled area in FIG15 , as the first area. In this way, the low-orbit satellite designs the weight of the receiving beam so that the main lobe of the receiving beam of the low-orbit satellite does not point to the first area, such as adjusting the null direction of the receiving beam to point to the first area. Thereby, the uplink interference caused by the uplink transmission of the high-orbit terminal to the uplink reception of the low-orbit satellite can be reduced.

[0148] For another example, a low-orbit satellite determines the INR generated by terminals served by each high-orbit satellite in each geographic area, identifying or recognizing geographic areas where interference intensity exceeds a preset value. The low-orbit satellite then determines the frequency domain configuration information corresponding to the geographic area where interference intensity exceeds the preset value based on the frequency domain configuration information associated with the geographic area in the terminal information transmitted by the high-orbit satellite. When the low-orbit satellite's receive beam is directed toward the geographic area where interference intensity exceeds the preset value, frequency domain resource scheduling is performed to ensure that the uplink frequency band of the low-orbit satellite does not overlap with the frequency band or frequency domain of the uplink transmission of the high-orbit satellite, as shown in Figure 9.

[0149] It can be seen that in the high-orbit uplink interference scenario shown in Figure 14, the high-orbit satellite system is the interferer and the low-orbit satellite system is the interfered party. After the high-orbit satellite periodically reports terminal information related to the low-orbit satellite (such as wave position scheduling information, user information of the scheduled wave position, and frequency domain configuration information associated with the scheduled wave position) to the low-orbit satellite system, the low-orbit satellite can calculate the total uplink interference based on the above interference information. If the total uplink interference is less than or equal to the interference threshold, the low-orbit satellite system can coexist with the high-orbit satellite system uplink on the same frequency to improve spectrum utilization. If the total uplink interference is greater than the interference threshold, the low-orbit satellite system can reduce the uplink interference of the high-orbit terminal to the low-orbit satellite by beam weight design or non-overlapping frequency bands.

[0150] In addition, the scenario considered in the embodiments of the present application is the interference caused by the uplink transmission of a high-orbit terminal to the uplink reception of a low-orbit satellite, rather than the downlink interference between high and low orbits, such as the interference caused by the downlink transmission of a low-orbit satellite to the high-orbit terminal, and the interference caused by the downlink transmission of a high-orbit satellite to the low-orbit terminal. In addition, the embodiments of the present application first analyze the interference situation and then perform interference coordination operations, which also avoids the problem of low spectrum utilization caused by blindly making the high-orbit terminal avoid a certain frequency domain resource to reduce the uplink interference to the low-orbit satellite.

[0151] In another embodiment, the information processing method described in FIG8 can also be applied to interference scenarios involving large and small towers, analyzing the total uplink interference generated by the uplink transmission of terminals served by the small tower on the uplink reception of the large tower. For example, the second network device includes, but is not limited to, the micro base station 110c shown in FIG3 , and the terminals served by the second network device include, but are not limited to, the printer 120e, mobile phone 120f, and computer 120g shown in FIG3 . The first network device is the macro base station 110b shown in FIG3 , and the terminals served by the first network device include, but are not limited to, the mobile phone 120a shown in FIG3 . The macro base station 110b receives terminal information from at least one micro base station, including the number of terminals served by the at least one micro base station, the location information of the at least one terminal served by the micro base station, and equivalent isotropically radiated power information. Based on the terminal information, the macro base station 110b determines the total uplink interference generated by the terminals served by the at least one micro base station on the macro base station 110b. In this way, the macro base station 110b can determine the total uplink interference generated by the uplink transmission of the terminals served by the at least one micro base station on the uplink reception of the macro base station 110b. Furthermore, the interference coordination operation described in the embodiments of the present application can be used to reduce interference and improve spectrum utilization. Optionally, the embodiment of the present application may also adopt various optional implementations of the method described in Figure 8, which will not be described in detail here.

[0152] In another embodiment, the information processing method described in FIG8 can also be applied to interference scenarios involving large and small towers, analyzing the total uplink interference generated by the uplink transmissions of terminals served by the large tower on the uplink reception of the small tower. For example, a first network device includes, but is not limited to, the micro base station 110c shown in FIG3 , and the terminals served by the first network device include, but are not limited to, the printer 120e, mobile phone 120f, and computer 120g shown in FIG3 . A second network device is the macro base station 110b shown in FIG3 , and the terminals served by the second network device include, but are not limited to, the mobile phone 120a shown in FIG3 . The micro base station 110c receives terminal information from the macro base station, including the number of terminals served by the macro base station, their locations, and equivalent isotropically radiated power (EIRP) information. Based on the terminal information, the micro base station 110c determines the total uplink interference generated by the terminals served by the macro base station on the micro base station 110c. In this way, the micro base station 110c can determine the total uplink interference generated by the uplink transmissions of the terminals served by the macro base station on the uplink reception of the micro base station 110c. Furthermore, the interference coordination operation described in the embodiments of the present application can be employed to reduce interference and improve spectrum utilization. Optionally, the embodiment of the present application may also adopt various optional implementations of the method described in Figure 8, which will not be described in detail here.

[0153] In the embodiments provided by the present application, the scheme of the information processing method provided by the embodiment of the present application is introduced from the perspective of each device itself and from the perspective of interaction between each device. It is understandable that each device, such as the first network device, the second network device, the terminal, the low earth orbit satellite, the geostationary orbit satellite, etc., in order to achieve the above functions, includes a hardware structure and / or software unit corresponding to each function. Those skilled in the art should easily appreciate that, in conjunction with the units and algorithm steps of each example described in the embodiment disclosed in this application, the present application can be implemented in the form of hardware or a combination of hardware and computer software. Whether a function is executed in the form of hardware or computer software driving hardware depends on the specific application and design constraints of the technical solution. Professional and technical personnel can use different methods to implement the described functions for each specific application, but such implementation should not be considered to exceed the scope of this application.
