Description

Technical Field

[0001] The present invention relates to the field of communication technologies, and in particular to an information processing method, device and equipment. Background Art

[0002] In the existing base station system, a cellular networking architecture is usually adopted. Among them, the cellular mobile communication network refers to a "mobile communication network" that divides a service area into several cellular adjacent cells and adopts frequency space multiplexing technology. The cellular mobile communication network consists of three parts: a mobile phone exchange, a base station and a mobile station. Specifically, the mobile phone exchange is connected to the local telephone network to realize the communication between fixed users and mobile users, and between mobile users. In this network, a mobile exchange serves a geographical area, and the service area formed by a mobile exchange is composed of several cellular adjacent wireless cells. Each cell is equipped with a base station responsible for the communication of mobile users in the cell. There are two types of topological combination methods of base stations: center excitation and vertex excitation. The existing methods are mostly vertex excitation.

[0003] In addition, the current base station sensing method is a full-area coverage solution that is self-transmitting and self-receiving. Existing communication base stations all have their own sensing functions, and a single station can solve the communication and sensing needs within its own range.

[0004] However, the networking mode of existing base stations currently only considers ground communication. Once it is necessary to perceive low altitude in the future, the existing networking mode cannot meet the demand; and the existing synaesthesia base stations are currently mostly self-transmitting and self-receiving. If it is required to still network according to the vertex excitation mode, the requirements for synaesthesia base stations will be very high. Specifically: On the one hand, the existing method needs to receive the near-end perception information, which means that when receiving the near-end large signal, the base station is not saturated, which makes the isolation requirement of the base station very high, and the existing base station cannot meet the requirements. On the other hand, the vertical scanning capability of the existing base station is only 24°~26°. Considering the common mechanical downtilt and electronic preset downtilt in the existing network, the coverage angle above the horizontal plane is currently very limited. Therefore, when the angle is limited, the corresponding coverage height of the near end will also be very low, which cannot meet the needs of low-altitude coverage. If a single station is allowed to cover the entire low-altitude airspace, the vertical scanning angle needs to be expanded to no less than 120°, which is about 5 times the existing capability, which cannot be completed at present. On the other hand, in the case of 1:1 networking of communication and perception, the cost will increase significantly.

[0005] Based on the above, using the existing coverage solution for low-altitude perception will require high isolation and high vertical scanning range, which the existing hardware cannot meet, resulting in the inability to achieve low-altitude perception. Summary of the invention

[0127] In order to make the technical problems, technical solutions and advantages to be solved by the present invention more clear, a detailed description will be given below with reference to the accompanying drawings and specific embodiments.

[0128] The present invention aims at solving the problem that the signal coverage scheme in the existing technology cannot support low-altitude perception, and provides an information processing method, such as Figure 1 As shown, including:

[0129] Step 11: Setting a signal coverage mode of at least one synaesthesia base station; wherein the signal coverage mode includes: communication signal coverage on the ground within a first area; communication signal and perception signal coverage in a target air area of ​​a second area, and perception signal coverage on the ground of the second area; the distance between any position in the first area and the synaesthesia base station is less than a first threshold, and the distance between any position in the second area and the synaesthesia base station is greater than a second threshold.

[0130] Among them, the above signal coverage mode can be understood as: the telepathic base station performs ground communication at the near end, communicates and senses at the far end at low altitude, and performs ground sensing at the far end, but it is not limited to this.

[0131] The information processing method provided by the embodiment of the present invention sets a signal coverage mode of at least one synaesthesia base station; wherein the signal coverage mode includes: communication signal coverage on the ground within the first area; communication signal and perception signal coverage in the target air area of ​​the second area, and perception signal coverage on the ground of the second area; the distance between any position in the first area and the synaesthesia base station is less than a first threshold, and the distance between any position in the second area and the synaesthesia base station is greater than a second threshold; it can support avoiding the base station from receiving near-end large signals, thereby circumventing high isolation requirements; and avoiding near-end requirements for coverage height, thereby reducing vertical scanning range requirements; based on this, this solution can be implemented on the basis of existing hardware equipment (after certain improvements, such as conventional base stations + antennas) to support low-altitude perception.

[0132] Furthermore, the information processing method further includes: setting the synaesthesia base station to adopt a self-transmitting and self-receiving mode for the perception signal of the target aerial area, and to adopt a self-transmitting and self-receiving mode and a self-transmitting and other-receiving mode for the perception signal of the ground of the second area.

[0133] In this way, seamless coverage of communication at the near end (first area) can be ensured, and seamless coverage of perception can also be ensured.

[0134] Among them, there is a perception blind area in the first area; the information processing method also includes: when the overlapping area in the horizontal direction between the synesthesia base stations is less than a third threshold, controlling the synesthesia base stations to cover the perception blind area with each other; when the overlapping area is greater than or equal to the third threshold, setting an auxiliary base station to cover the perception blind area.

[0135] This can support multiple modes and accurately cover perception blind spots.

[0136] In the embodiment of the present invention, the communication signal is sent in the form of a continuous wave, and the perception signal is sent in the form of a pulse wave.

[0137] This can ensure the normal communication; and greatly reduce the isolation between the receiving and transmitting channels of the perception signal, reduce the demand for perception base stations (i.e., inter-sensory base stations), and support the realization of the above-mentioned signal coverage mode.

[0138] Among them, the communication signal and the perception signal adopt a time-division multiplexing hardware structure, and / or the transceiver channel of the perception signal adopts time-division multiplexing within the symbol.

[0139] This can support a higher level of utilization of resources.

[0140] Furthermore, the information processing method further includes: setting a collaborative working mode between the synesthesia base station and the communication base station; wherein the collaborative working mode includes: (1) the synesthesia mode of the communication base station is a perception mode, the synesthesia base station sends a perception signal to the second area, the synesthesia base station receives the perception signal reflected by the ground of the target aerial area and the second area, and the communication base station receives the perception signal reflected by the ground of the second area; (2) the synesthesia mode of the communication base station is a non-working mode, the synesthesia base station sends a perception signal to the second area, the synesthesia base station receives the perception signal reflected by the ground of the target aerial area and the second area, and the communication base station does not work; (3) the synesthesia mode of the communication base station is a communication mode, the synesthesia base station sends a perception signal to the second area, the synesthesia base station receives the perception signal reflected by the ground of the target aerial area, and the communication base station performs uplink communication or does not work.

[0141] In this way, the normal implementation of the above signal coverage mode can be ensured, and the coordination of communication and perception can be accurately achieved. Among them, the above (1) can specifically include: when the communication base station is in the perception mode, in the communication time slot or symbol (i.e., in the communication time slot or symbol), the communication base station and the perception base station (i.e., the synesthesia base station) both communicate; when the synesthesia base station is in the perception time slot or symbol, the synesthesia base station uses the full vertical scanning range coverage for perception (i.e., the synesthesia base station perceives within the entire vertical scanning range), and the communication base station performs ground perception reception. A single group perception mode of a perception station (i.e., a perception base station) that transmits and receives automatically at low altitude (i.e., perceives alone in the air), and a joint perception mode of a perception station transmitting and receiving automatically + a perception-communication station (i.e., a perception base station + a communication base station) transmitting and receiving automatically is adopted on the ground. The above (2) can specifically include: when the communication base station is in the non-working mode, in the communication time slot or symbol, the communication base station and the perception base station both communicate; when the communication base station is in the perception time slot or symbol, the perception base station uses the full vertical scanning range coverage, and the communication base station does not work. The above (3) may specifically include: when the communication base station is in communication mode, during the communication time slot or symbol, the communication base station and the perception base station both communicate; during the perception time slot or symbol, the perception base station beam scanning range is the area above the horizontal plane (of the ground), no ground perception is performed, and the (conventional) communication base station performs uplink communication or does not work.

[0142] The communication base station performs uplink communication or does not work, including: (1) when the amount of decrease in the perceived quality of the pre-perception measurement performed by the synesthesia base station within a first time period is less than or equal to a fourth threshold, the communication base station performs uplink communication; (2) when the amount of decrease is greater than the fourth threshold, the communication base station does not work.

[0143] In this way, the coordination between the communication base station and the synaesthesia base station can be accurately achieved. Wherein, the uplink communication may include the uplink part of the communication of the conventional communication system, but is not limited thereto.

[0144] Furthermore, the information processing method also includes: determining the perception range of the synesthesia base station according to the coverage distance and coverage height of the synesthesia base station; determining the beam scanning range of the synesthesia base station according to the coverage distance, horizontal scanning angle, vertical scanning angle and blind spot distance of the synesthesia base station; determining the networking mode of the synesthesia base station according to the perception range and beam scanning range; wherein the blind spot distance corresponds to the perception blind spot existing in the first area.

[0145] In this way, the networking of synaesthesia base stations can be accurately realized.

[0146] The step of determining the perception range of the synaesthesia base station according to the coverage distance and coverage height of the synaesthesia base station comprises: obtaining a maximum perception distance, a coverage height, and a height of the synaesthesia base station; obtaining a maximum station spacing according to the maximum perception distance, the coverage height, and the height of the synaesthesia base station; determining the coverage distance of the synaesthesia base station according to the maximum station spacing; and determining the perception range of the synaesthesia base station according to the coverage distance and a horizontal scanning angle.

[0147] In this way, the sensing range (information) of the synaesthesia base station can be accurately obtained.

[0148] Furthermore, the information processing method also includes: determining the blind spot distance according to the speed of light and the perception transceiver switching time of the telepathic base station; determining the vertical scanning angle according to the blind spot distance and the coverage height; wherein the perception transceiver switching time is greater than the minimum switching time for the perception transceiver of the telepathic base station.

[0149] In this way, the blind area distance and the vertical scanning angle can be accurately obtained.

[0150] The information processing method provided by the embodiment of the present invention is described below by way of example.

[0151] In view of the above technical problems, an embodiment of the present invention provides an information processing method, which can be specifically implemented as a collaborative design of a synaesthesia base station and its networking solution. The solution is implemented by the synaesthesia base station based on the perception signal being a pulse wave and the communication signal being a continuous wave (corresponding to the above communication signal being sent in the form of a continuous wave, and the perception signal being sent in the form of a pulse wave). Among them, the base station performs ground communication at the near end (corresponding to the above first area) (corresponding to the above ground in the first area being covered by the communication signal), and performs communication and perception at the far end low altitude (corresponding to the above target air area in the second area) (corresponding to the above target air area in the second area being covered by the communication signal and the perception signal) and performs ground perception at the far end (corresponding to the above ground in the second area being covered by the perception signal). Perception and communication, ground and low altitude all use time division multiplexing (corresponding to the above perception signal transceiver channel using time division multiplexing within the symbol, and / or, the communication signal and the perception signal use a time division multiplexing hardware structure). Remote low-altitude perception adopts a self-transmitting and self-receiving mode (corresponding to the above-mentioned setting that the synesthesia base station adopts a self-transmitting and self-receiving mode for the perception signal of the target aerial area), and remote ground perception adopts a self-transmitting and self-receiving + self-transmitting and receiving model (corresponding to the above-mentioned self-transmitting and self-receiving and self-transmitting and receiving modes for the perception signal of the ground in the second area). Based on this, both the seamless coverage of the near-end communication and the seamless coverage of the perception can be guaranteed.

[0152] Specifically, the waveform of the sensing signal adopts a pulse wave, and the transmission and reception are completed within a time slot, which is inconsistent with the continuous wave of traditional sensing. The pulse wave can make the sensing transmission and reception not at the same time point, so the receiving channel and the transmitting channel will not work at the same time, which can greatly reduce the isolation between the transmitter and the receiver, and reduce the demand for base stations. At the same time, the reduction in isolation requirements allows the base station's transmission power to be increased, thereby increasing the coverage distance of the base station.

[0153] Among them, the coverage mode of a single station (i.e., a telepathic base station) uses pulse signals, so there will be a near-end blind area (corresponding to the above-mentioned perception blind area), where the blind area distance is d 盲 , d 盲 =ct 设 / 2 (corresponding to the blind spot distance determined according to the speed of light and the sensing transceiver switching time of the telepathic base station). The pulse transceiver switching time t can be set according to the required blind spot distance. 设 ; The minimum switching time for sensing transceiver is t, which depends on the transceiver switch switching capability of the existing base station. Among them, the sensing transceiver switching time (i.e. the switching time for pulse transceiver) corresponding to the blind area distance that needs to be set during setting is t 设 >t (corresponding to the above-mentioned sensing and receiving switching time being greater than the minimum switching time of the sensing and receiving base station), the existing base station hardware capability can meet the demand. Wherein, c represents the speed of light.

[0154] In addition, the use of pulse signals can optimize the requirements for the vertical scanning range. Specifically: Under normal circumstances, the perception needs to scan a scanning range of 0 to 90 degrees above the horizontal plane; and the vertical scanning range angle θ of this solution depends on the blind spot distance and the vertical coverage height (corresponding to the above-mentioned determination of the vertical scanning angle according to the blind spot distance and the coverage height (i.e., the vertical coverage height): The conventional coverage requirement α in the existing network is usually 25°. Based on this, by adopting this solution, the vertical scanning range can reach the capability that the existing hardware can achieve, thus reducing the demand for hardware.

[0155] Regarding time division multiplexing, possible implementations are as follows:

[0156] Taking the conventional 30KHz subcarrier as an example, a certain slot is set for sensing, such as Figure 2As shown, 0 to 5 are communication symbols, 6 to 9 are protection bands, and symbols 10 to 13 are sensed, such as symbol 10. Assume that the first 0.6us in Symbol 10 is sensed transmission (i.e., sensed signal transmission); the following 2us is the switch time (corresponding to the blind area), that is, the switch from sensed transmission to sensed reception (i.e., sensed signal reception), and no sense is performed during the switch time; the following 4us is for sensed (signal) reception; the entire 6.6us is taken as a unit, and repeated 5 times in a symbol. In this way, hardware time division multiplexing is used between perception and communication, and the transmission and reception within perception are also time division multiplexed.

[0157] Among them, the mode of the perception signal is a low peak-to-average ratio signal such as the ZC (Zadoff-Chu) sequence or LFM (linear frequency modulation). Compared with traditional communication signals, the peak-to-average ratio is reduced from 11dB to 3dB or lower, which can increase the transmitter power and expand the perception range.

[0158] Specifically, the blind spot distance related content can be shown in the following table:

[0159]

[0160]

[0161] The vertical coverage height can be Figure 3 As shown in h, the near-end blind zone distance can be Figure 3 d in 盲 As shown, the coverage radius of a single station can be Figure 3 As shown in R', the vertical scanning angle can be Figure 3 As shown in θ, in addition, the coverage distance can be Figure 3 As shown in R.

[0162] Specifically, the coverage of a single station (three sectors) using the above signal method is as follows: Figure 4 As shown, the area filled with diagonal lines is the near-end ground communication area, and the area filled with squares is the far-end low-altitude communication and perception area and the ground perception area. The perception and communication hardware can adopt a time division multiplexing mode.

[0163] Based on the above signal coverage mode, the scheduling mode of the synaesthesia station (i.e., the perception base station) and the conventional communication (base station) in the time domain (corresponding to the cooperative working mode between the synaesthesia base station and the communication base station set above) is as follows: Figure 5 As shown, including the following:

[0164] 1. First, determine the communication sensing mode of the conventional communication base station (i.e., set the communication station sensing mode), which can be set to: sensing mode, non-working mode or receiving mode (corresponding to the above communication modes). It can be set manually or in other automated ways, which is not limited here.

[0165] 2. When the communication base station is in the sensing mode, in the communication time slot or symbol (also referred to as in the communication time slot or symbol), the communication base station and the sensing base station (i.e., the synesthesia base station) both communicate; when the synesthesia base station is in the sensing time slot or symbol, the synesthesia base station uses the full vertical scanning range coverage for sensing (i.e., the sensing station senses in the full scanning range), and the communication base station senses and receives on the ground. A single group sensing mode of the sensing station (i.e., the sensing base station) that is self-transmitting and self-receiving is formed at low altitude (i.e., separate sensing in the air), and a joint sensing mode of the sensing station self-transmitting and self-receiving + sensing-communication station (i.e., sensing base station + communication base station) that is self-transmitting and self-receiving is adopted on the ground (i.e., joint sensing on the ground); the synesthesia mode corresponding to the above-mentioned communication base station is the sensing mode, the synesthesia base station sends a sensing signal to the second area, the synesthesia base station receives the sensing signal reflected by the ground of the target air area and the second area, and the communication base station receives the sensing signal reflected by the ground of the second area.

[0166] 3. When the communication base station is in a non-working mode, in the communication time slot or symbol, the communication base station and the perception base station both communicate; when the communication base station is in the perception time slot or symbol, the perception base station adopts full vertical scanning range coverage (i.e., the perception station perceives in the full scanning range), and the communication base station does not work; the synaesthesia mode corresponding to the above-mentioned communication base station is a non-working mode, the synaesthesia base station sends a perception signal to the second area, the synaesthesia base station receives the perception signal reflected by the target aerial area and the ground of the second area, and the communication base station does not work.

[0167] 4. When the communication base station is in communication mode, in the communication time slot or symbol, the communication base station and the sensing base station both communicate; in the sensing time slot or symbol, the sensing base station beam scan range is the area above the horizontal plane (of the ground), and no ground sensing is performed. The collaborative mode of the (conventional) communication base station and the sensing base station (i.e., the sensing station, which can communicate and sense) works according to the following logic:

[0168] ① First, the sensing base station performs pre-sensing measurement (i.e., sensing station sensing pre-measurement) for a period of time t 测 Changes in internal perception accuracy (such as distance accuracy, speed accuracy, angle accuracy, etc.);

[0169] ② When the accuracy drops by M% and exceeds the threshold value N (that is, the perceived quality drops significantly), the communication station does not work in the perception time slot; corresponding to the above situation where the drop is greater than the fourth threshold, the communication base station does not work.

[0170] ③ When the accuracy decreases by M% but does not exceed the threshold value N (i.e., there is no significant decrease in the perceived quality), the communication station only performs uplink communication in the perception time slot and does not perform downlink communication, that is, when there is no significant decrease in the perceived quality, uplink supplementation is performed, including: the communication station sets the uplink mode to perform ground uplink supplementation (corresponding to the above-mentioned case where the decrease in the perceived quality of the pre-perception measurement performed by the telepathic base station within the first time period is less than or equal to the fourth threshold, the communication base station performs uplink communication); it may also include: the perception station performs beamforming settings (so as to scan the area above the horizontal plane) to achieve independent perception in the air.

[0171] ④ Repeat steps ① to ③ at regular intervals to determine the working mode of the existing communication station.

[0172] The above logic corresponds to the synaesthesia mode of the above communication base station as the communication mode, the synaesthesia base station sends a perception signal to the second area, the synaesthesia base station receives the perception signal reflected by the target aerial area, and the communication base station performs uplink communication or does not work.

[0173] Furthermore, the networking mode of the sensing base station may include the following contents:

[0174] The first step is to calculate the maximum sensing distance r based on the existing capabilities of the base station max (corresponding to the above maximum sensing distance). First, the sensing capability P of the existing base station can be calculated according to the radar equation r , Where P t is the transmission power of the base station, G t is the base station’s transmitting antenna gain, G r is the transmitting antenna gain of the base station, λ is the wavelength of the transmitting signal of the base station, and σ is the radar reflection cross-sectional area of ​​the reflecting object (mostly 0.01m for drones). 2 ~0.1m 2 ), P rmin is the minimum detection power of the base station sensing signal, and R is the coverage distance of the base station, which can be a set known quantity and is not greater than the implementation capability of the hardware.

[0175] The second step is to calculate the maximum station spacing r 站max According to the required coverage height h (i.e. vertical coverage height, corresponding to the above coverage height), and the station height h 站 (corresponding to the height of the above-mentioned synaesthesia base station) is calculated, Corresponding to the above, the maximum sensing distance, coverage height and height of the synaesthesia base station are obtained; according to the maximum sensing distance, coverage height and height of the synaesthesia base station, the maximum station spacing is obtained.

[0176] The third step is to determine the single-station coverage area (corresponding to the sensing range of the above-mentioned synaesthesia base station). Specifically, the coverage distance R (R <r 站max ; Corresponding to the above-mentioned determination of the coverage distance of the telepathic base station according to the maximum station spacing), and the communication horizontal coverage angle φ (i.e., the horizontal scanning angle φ), determine the single-station coverage area (corresponding to the above-mentioned determination of the sensing range of the telepathic base station according to the coverage distance and the horizontal scanning angle). Usually, the coverage area can be "M" type, "inverted V" type, or "concentric fan type", which is not limited here.

[0177] The fourth step is to calculate the coverage distance R, horizontal scanning angle φ, vertical scanning angle θ and near-end blind zone distance d of the single station. 盲 , and feeds back to the BBU (baseband processing unit) and AAU (active antenna processing unit), thereby completing the setting of the single-station beam scanning area (corresponding to the above-mentioned beam scanning range) of the baseband and radio frequency units (corresponding to the above-mentioned determination of the beam scanning range of the telesensory base station according to the coverage distance, horizontal scanning angle, vertical scanning angle and blind spot distance of the telesensory base station).

[0178] The fifth step is to determine the single-station coverage area and the single-station beam scanning area, and to perform reasonable dense paving (corresponding to the above-mentioned determination of the networking mode of the telepathic base station according to the sensing range and the beam scanning range) in accordance with the principle of no overlapping area in the longitudinal direction and as little overlap as possible in the horizontal direction (the threshold can be set) after determining the single-station coverage area and the single-station beam scanning area. There are two dense paving modes: ① If the (horizontal direction) overlapping area is less than m%, the base stations cover each other's blind areas (corresponding to the above-mentioned control of the telepathic base stations to cover each other's sensing blind areas when the overlapping area between the telepathic base stations in the horizontal direction is less than the third threshold); ② If the overlapping area>m%, a small number of auxiliary base stations are set to complete the coverage of the near-end blind area of ​​the main telepathic base station (corresponding to the above-mentioned setting of auxiliary base stations to cover the sensing blind areas when the overlapping area is greater than or equal to the third threshold), and the hardware of the auxiliary station is completely consistent with that of the main station (that is, the hardware itself has completely consistent capabilities).

[0179] The following is a specific example of the networking of perception base stations.

[0180] Networking Example 1:

[0181] Assuming that the distance between conventional communication base stations is 300 meters, the vertical range coverage height of the sensing base station (i.e., the telepathic base station) is about 300 meters, the single-station coverage distance is about 600 meters, the single-sector coverage radius is about 500 meters, and the blind area (radius) is about 170 meters. Based on this, the single-sector sensing coverage (i.e., the selected single-sector coverage area) of the sensing base station is as follows: Figure 6As shown in the figure, the single sector coverage area covers three areas: 1, 2, and 3. Based on the above information, the vertical scanning angle can be set to 82 degrees, the horizontal scanning angle can be set to 82 degrees, and then the single station coverage area and single station beam scanning area of ​​the sensing base station can be obtained. In this case, dense paving (i.e. networking) can be obtained. Figure 7 The networking result shown (the coverage area of ​​the communication base station is not shown): a group of sensing base stations (see the solid line column - including sensing base station 1, sensing base station 2, sensing base station 3 and sensing base station 4, i.e., inter-sensing base stations 1, 2, 3, 4) are deployed every two columns (communication base stations - see the dotted line column), and the ratio of sensing base stations to communication base stations is about 1:2; all areas in the area are seamlessly connected, and uninterrupted networking of full-area sensing can be completed. In this case, the number of AAUs is reduced by 66% compared with 1:1 networking.

[0182] Specifically, it is possible to: calculate the coverage distance, blind spot radius, etc. of the perception base station according to the hardware capabilities of the perception base station (such as transmission power, pulse width, etc.), and clarify the station spacing of the perception base station and the coverage height of the area to be covered (i.e., vertical range coverage height) in advance, so as to calculate the coverage radius of a single sector; subsequently, obtain the single-sector coverage graph according to the blind spot radius and the coverage radius, and then calculate the horizontal scanning angle according to the width of the area covered by the single sector, and calculate the vertical scanning angle according to the coverage height and the coverage radius, but it is not limited to this.

[0183] in addition, Figure 6 The “selected single-sector coverage area” in the description belongs to a partial area of ​​the “selected complete single-sector coverage area”. The “selected single-sector coverage area” can also be understood as: the single-sector coverage area actually required, but is not limited thereto.

[0184] In addition, the coverage area mentioned above can also be expressed as a coverage range, which is not limited here.

[0185] Networking Example 2:

[0186] Assuming that the conventional communication base station spacing is 300 meters, the vertical range coverage height of the sensing base station is about 300 meters, the single station coverage distance is about 700 meters, the single sector coverage radius is about 600 meters, and the blind area (radius) is about 300 meters. Based on this, the single sector coverage (of the sensing base station) (i.e., the selected single sector coverage area) is as follows: Figure 8 As shown in the figure, the single sector coverage area can cover five areas: 1, 2, 3, 4, and 5. Based on the above information, the vertical scanning angle can be set to 67 degrees and the horizontal scanning angle can be set to 73 degrees, and then the single-station coverage area and single-station beam scanning area of ​​the sensing base station can be obtained. In this case, dense paving can be obtained. Fig. 9The networking result shown (the coverage area of ​​the communication base station is not shown): a group of sensing base stations (see the solid line column - including sensing base station 1, sensing base station 2, sensing base station 3 and sensing base station 4, i.e., inter-sensing base stations 1, 2, 3, 4) are deployed every three columns (communication base stations - see the dotted line column), and the ratio of sensing base stations to communication base stations is about 1:3; since the sensing is self-transmitting and self-receiving, the overlapping area (the coverage area of ​​2 sensing base stations can overlap, such as Fig. 9 There is no interference between the 4th column and the 3rd dotted column in the figure, and uninterrupted networking can be achieved in the entire area. In this case, the number of AAUs is reduced by 75% compared to 1:1 networking.

[0187] Networking Example 3:

[0188] Assuming that the conventional communication base station spacing is 300 meters, the vertical range coverage height of the sensing base station is about 300 meters, the single station coverage distance is about 850 meters, the single sector coverage radius is about 600 meters, and the blind area (radius) is about 300 meters. Based on this, the single sector coverage (of the sensing base station) (i.e., the selected single sector coverage area) is as follows Fig.10 As shown in the figure: the single-sector coverage area covers areas 1 to 13; based on the above information, the vertical scanning angle can be set to 67 degrees and the horizontal scanning angle can be set to 120 degrees (one base station includes three sectors - sector 1, sector 2, and sector 3), and then the single-station coverage area and single-station beam scanning area of ​​the sensing base station are obtained; among which, the central area of ​​the single-sector coverage area is the near-end blind area (specifically, it may include Fig.10 The middle blind area includes the 5 polygonal blocks involved in the area, and the blind area radius is equal to Fig.10 The fan radius of the area included in the blind area). In order to reduce overlapping coverage, combined Fig.11 (Single-station coverage mode - the coverage area of ​​the communication base station is not shown) It is possible to consider setting up auxiliary station 1 and auxiliary station 2 on both sides of the base station coverage area, and the vertical scanning angle of the auxiliary station is consistent with that of the main station, and the horizontal scanning angle (the scanning angle from the leftmost end to the rightmost end of the area corresponding to the auxiliary station) is reduced to the corresponding angle (based on the perception signals of the two auxiliary stations that can cover the blind area, for example, the horizontal scanning angle of auxiliary station 1 is reduced to about 40 degrees, and the horizontal scanning angle of auxiliary station 2 is reduced to about 70 degrees), thereby completing the coverage of the central blind area (specifically, as shown in Fig.12 As shown, Fig.12 The master station in the figure refers to the sensing base station, the auxiliary station 1 and the auxiliary station 2 are also sensing base stations, and the other base stations are communication base stations, wherein the auxiliary station 1 and the auxiliary station 2 may each have only one sector for sensing signal coverage, but this is not limited to this). In this embodiment, the ratio of the sensing base station to the communication base station is about 5:42 (see Fig.12 - The coverage area of ​​the communication base station is not shown). In this case, compared with 1:1 networking, the number of AAUs is reduced by 88%.

[0189] It should be noted that the above Figures 6 to 12 In the figure, the dot extending outward in three directions from the vertex of the polygon represents a base station (specifically, the dot representing a base station has three lines extending outward, and a dot is connected to the end of each line); in addition, the relevant contents of the above embodiments can be referenced to each other, and the repeated parts will not be repeated.

[0190] Based on the above, the solution provided by the embodiment of the present invention specifically includes the following contents:

[0191] 1. A collaborative design of a synaesthesia base station and its networking solution, wherein: the communication signal adopts a continuous wave, the perception signal adopts a pulse wave, and the hardware part of the perception and communication signals adopts a time division multiplexing structure (that is, the same set of hardware is used for perception or communication). The internal transceiver channel of the perception signal adopts the time division multiplexing within the symbol.

[0192] 2. A collaborative design of inter-sensory base stations and a networking solution thereof, wherein: the near end of the single sensing station (i.e., sensing base station) is ground coverage, and the far end is low-altitude and ground sensing coverage, and the near end has a certain blind spot for sensing. If the overlapping area between the sensing base stations is low, the near-end blind spots are covered by each other; if the overlapping area between the sensing base stations is high, an auxiliary station is used to cover the near-end blind spot (i.e., the single sensing station performs ground communication at the near end, communicates and senses at the far end at low altitude, and performs ground sensing at the far end; if there is an overlapping area between the sensing base stations, the near-end blind spots are covered by each other, or an auxiliary station is used to cover the near-end blind spot).

[0193] 3. A collaborative design of a sensing base station and its networking solution, wherein the collaborative working mode of the sensing base station and the communication base station includes: the sensing base station and the communication base station communicate within a communication time unit (i.e., a communication time slot or symbol); there are three modes of the communication base station within the sensing time unit (sensing time slot or symbol): ① sensing mode: the sensing station transmits and receives by itself, and the communication station cooperates with the sensing station to transmit and receive by itself; ② no working mode: the sensing station senses the entire area, and the communication station does not work; ③ communication mode: the sensing station senses at low altitude, and the communication station performs ground uplink supplement (uplink communication) or does not work according to the situation of the sensing station.

[0194] 4. A collaborative design of synaesthesia base stations and their networking solutions, including: determining the perception range of a single station according to the coverage distance and coverage height of the single station, and feeding back relevant information (such as the near-end blind spot distance, etc.) to the BBU and AAU to determine the beam scanning range, and subsequently performing dense paving according to the single station perception range and the beam scanning range.

[0195] In summary, this scheme proposes a collaborative design of interaceptive base stations and their networking scheme: the near-end completes ground communication coverage, and the far-end low-altitude completes communication and perception coverage; communication and perception, as well as internal transmission and reception of perception, all adopt time division multiplexing. For low-altitude perception, there are blind spots at the near end, and the method of alternate station coverage can be adopted. The perception station and the communication station work together in the perception time slot, and the communication station can perform collaborative perception or uplink supplement in the perception time slot. When networking, the perception base stations can cover each other's near-end blind spots to complete topological dense paving; when the overlapping area of ​​the perception base stations is too large, the perception stations do not cover each other's blind spots, and auxiliary stations can be used to cover the near-end blind spots instead.

[0196] In addition, this solution can use ground macro base stations to complete low-altitude coverage; the usage scenarios of this solution can be low-altitude communication perception and ground communication coverage, but it is not limited to this.

[0197] Based on the above, compared with the traditional solution, this solution has the following advantages:

[0198] 1. The low peak-to-average ratio sensing signal mode of the pulse wave is adopted. Compared with the continuous wave of traditional communication, it can reduce the direct isolation between the receiving channel and the transmitting channel, thereby increasing the system's transmission power and expanding the coverage range.

[0199] 2. When sensing time units, the communication station can have multiple working modes, which improves the efficiency of the time domain compared to traditional communication stations that simply do not work.

[0200] 3. The network mode of alternate-station coverage is adopted. Compared with the traditional network mode of self-surrounding coverage, it can reduce the requirements of the vertical scanning range of the base station for perception and expand the coverage range of the base station. At the same time, the coverage distance and blind spot can be set according to the needs, which is convenient for setting the coverage range of a single station, so as to support reasonable dense paving.

The hardware circuit includes a conventional very large scale integration (VLSI) circuit or gate array and existing semiconductors such as logic chips, transistors, or other discrete components. The module can also be implemented by a programmable hardware device, such as a field programmable gate array, a programmable array logic, a programmable logic device, etc.

It should be pointed out that for ordinary personnel in this technical field, several improvements and modifications can be made without departing from the principles of the present invention.
