Description

Technical Field

[0001] The present application relates to the field of communication technology, and in particular to a synaesthesia signal processing method, apparatus, base station equipment, computer-readable storage medium, and computer program product. Background Art

[0002] With the development of communication technology, a base station device has emerged that can take into account both communication and perception functions, that is, realize integrated inter-sensory communication. The communication function is used to support the development of low-altitude related businesses, while the perception function is mainly used for airspace supervision.

[0003] For the integrated interawareness technology, the radar sensing waveforms used are usually pulse waves and continuous waves. The continuous wave transmits and receives signals at the same time, but because its transmission power is limited by the full-duplex transmission and reception isolation of the base station, the farthest coverage is limited and can only be used for short-distance sensing coverage. The pulse wave transmission and reception signals are separated in time, which is used for far-point sensing coverage, but because there is a certain time difference between the transmitted pulse and the received echo, there is a blind spot in the near-point coverage.

[0004] Moreover, for synaesthesia integration technology, the structural configuration of the signal frame is a decisive factor. However, the current synaesthesia signal frame configuration used in the synaesthesia integration technology does not take into account comprehensive factors and cannot be applied to a variety of different perception scenarios.

[0054] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0055] The synaesthesia signal processing method provided in the embodiment of the present application can be applied to the application environment shown in FIG. 1. The first device 101 communicates with the second device 102 via a synaesthesia signal. Specifically, the first device 101 can determine the waveform type of the perception signal in the synaesthesia signal frame to be configured according to the perception range of the first device. The perception signal can be used for the first device 101 to sense the second device 102. After that, the perception signal length of the perception signal in the synaesthesia signal frame can be determined according to the perception performance requirements of the first device 101, and the signal arrangement position of the perception signal in the synaesthesia signal frame can be determined by using the perception signal length. Then, the waveform arrangement of the perception signal in the synaesthesia signal frame is completed by combining the waveform type and the signal arrangement position, thereby configuring the frame structure of the synaesthesia signal frame, and the synaesthesia signal frame can be used to realize communication with the second device 102. The first device 101 can be a base station device, and the second device 102 can be, but is not limited to, various types of low-altitude communication devices, such as drone devices, etc.

[0056] In one embodiment, as shown in FIG. 2 , a synaesthesia signal processing method is provided, and the method is applied to the first device 101 in FIG. 1 as an example for description, including the following steps:

[0057] Step S201, determining the waveform type of the perception signal in the synaesthesia signal frame to be configured according to the perception range of the first device 101; the perception signal is used to sense the second device 102 entering the perception range.

[0058] The sensing range refers to the range in which the first device 101 senses the second device 102. The first device 101 may be a base station device, and the second device 102 may be a low-altitude communication device that communicates with the base station device, such as a drone device. The synaesthesia signal frame is a signal frame used for information exchange between the first device 101 and the second device 102. The signal frame includes two parts, namely, a communication signal and a sensing signal. The communication signal is mainly used to realize the communication function, that is, for communication between the first device 101 and the second device 102, and the sensing signal is used to realize the sensing function, which can be used to sense the second device 102 that enters the sensing range of the first device 101. The waveform type refers to the signal waveform type used by the sensing signal.

[0059] Specifically, the first device 101 may determine the signal waveform type corresponding to the perception signal part in the synaesthesia signal frame to be configured according to the perception range of the first device 101 .

[0060] Step S102: determining the perception signal length of the perception signal in the synaesthesia signal frame according to the perception performance requirement of the first device 101, and determining the signal arrangement position of the perception signal in the synaesthesia signal frame by using the perception signal length.

[0061] The perception performance requirements are pre-set performance requirements used to characterize the level of perception performance, such as perception resolution requirements, perception accuracy requirements, false alarm rate requirements, missed detection rate requirements, and refresh rate requirements, etc. The perception signal length refers to the signal length of the perception signal in the synaesthesia signal frame, which can be characterized by the symbol length corresponding to the signal, and the signal arrangement position refers to the position of the perception signal in the synaesthesia signal frame.

[0062] Specifically, the first device 101 can also determine the signal length of the perception signal in the synaesthesia signal frame, that is, the perception signal length, according to the perception performance requirements set by it, and then use the determined perception signal length to determine the position of the perception signal in the synaesthesia signal frame, that is, the signal arrangement position of the perception signal in the synaesthesia signal frame.

[0063] Step S103, configuring the waveform arrangement of the perception signal in the synaesthesia signal frame according to the waveform type and the signal arrangement position, so as to complete the frame structure configuration of the synaesthesia signal frame.

[0064] The waveform arrangement refers to the waveform arrangement form of the perception signal in the synaesthesia signal frame. The waveform arrangement can be determined based on the waveform type and the signal arrangement position. For example, if the waveform type is a continuous wave, then the position in the synaesthesia signal frame that is consistent with the signal arrangement position can be configured as a continuous wave, thereby completing the waveform arrangement of the perception signal in the synaesthesia signal frame. After that, the frame structure configuration of the synaesthesia signal frame can be completed in combination with the waveform arrangement configuration of the communication signal in the synaesthesia signal frame.

[0065] In the above-mentioned synaesthesia signal processing method, the waveform type of the perception signal in the synaesthesia signal frame to be configured is determined by the first device 101 according to the perception range of the first device 101; the perception signal is used to sense the second device 102 entering the perception range; according to the perception performance requirements of the first device 101, the perception signal length of the perception signal in the synaesthesia signal frame is determined, and the signal arrangement position of the perception signal in the synaesthesia signal frame is determined by using the perception signal length; according to the waveform type and the signal arrangement position, the waveform arrangement of the perception signal in the synaesthesia signal frame is configured to complete the frame structure configuration of the synaesthesia signal frame. The present application determines the waveform type of the perception signal in the synaesthesia signal frame for sensing the second device 102 entering the perception range by obtaining the perception range of the first device 101, and can also determine the perception signal length of the perception signal in the synaesthesia signal frame according to the perception performance requirements of the first device 101, and use the perception signal length to obtain the signal arrangement position of the perception signal in the synaesthesia signal frame, so as to complete the waveform arrangement of the perception signal in the synaesthesia signal frame by combining the waveform type and the signal arrangement position, so as to complete the frame structure configuration of the synaesthesia signal frame. In this way, a universal frame structure configuration of the synaesthesia signal frame that combines the perception range and the perception performance requirements is provided, thereby improving the universality of the synaesthesia signal frame configuration.

[0066] In one embodiment, as shown in FIG3 , step S201 may further include:

[0067] Step S301: Acquire, according to device parameters of the first device, a maximum perception coverage range of a continuous wave corresponding to the first device and a minimum perception coverage range of a pulse wave corresponding to the first device.

[0068] The maximum perception coverage range of continuous waves refers to the maximum perception coverage capability range of continuous waves, while the minimum perception coverage range of pulse waves refers to the minimum perception coverage capability range of pulse waves. Generally speaking, the transmission power of continuous waves is limited by the full-duplex transceiver isolation of the base station, and the farthest coverage is limited, and only short-distance perception coverage can be performed. That is, the continuous wave has the farthest perceptible range, and this range is used as the maximum perception coverage range of continuous waves. Similarly, for pulse waves, the transmission and reception signals are separated in time, which is a half-duplex working mode. It can be used for far-point perception coverage, but due to a certain time difference between the transmission pulse and the reception echo, there is a blind spot in the near-point coverage, that is, the pulse wave has the nearest perceptible range, and this range is used as the minimum perception coverage range of pulse waves. Both the maximum perception coverage range of continuous waves and the minimum perception coverage range of pulse waves are determined by the device parameters of the first device 101. Therefore, the first device 101 can obtain its corresponding maximum perception coverage range of continuous waves and minimum perception coverage range of pulse waves according to its corresponding device parameters.

[0069] Step S302: determining the waveform type of the perception signal according to the perception range, the maximum perception coverage range of the continuous wave, and the minimum perception coverage range of the pulse wave.

[0070] After obtaining the perception range of the first device 101 and the maximum perception coverage range of the continuous wave and the minimum perception coverage range of the pulse wave corresponding to the first device 101, the waveform type used by the perception signal can be determined according to the above ranges.

[0071] In this embodiment, the first device 101 can obtain the maximum perception coverage range of the continuous wave and the minimum perception coverage range of the pulse wave according to its device parameters, and then combine the above ranges with the perception range to select the waveform type of the perception signal, so that the configured perception signal can meet the requirements of the perception range and further improve the accuracy of the perception signal configuration.

[0072] Further, as shown in FIG4 , step S302 may further include:

[0073] Step S401: When the maximum value of the perception range is less than or equal to the maximum perception coverage range of the continuous wave, determine that the waveform type of the perception signal is a first waveform type; the first waveform type indicates that the perception signal is a continuous wave.

[0074] If the maximum value of the perception range is less than or equal to the maximum perception coverage range of the continuous wave, that is, the coverage range of the continuous wave can already meet the perception range of the first device, then in this case, only the continuous wave is needed to meet the perception range of the first device, so the waveform type of the perception signal can be the first waveform type, and the first waveform type represents that the perception signal is entirely composed of continuous waves.

[0075] Step S402: When the maximum value of the perception range is greater than the maximum perception coverage range of the continuous wave and the minimum value of the perception range is greater than or equal to the minimum perception coverage range of the pulse wave, determine that the waveform type of the perception signal is a second waveform type; the second waveform type indicates that the perception signal is a pulse wave.

[0076] If the maximum value of the perception range is greater than the maximum perception coverage of the continuous wave, it indicates that the continuous wave alone cannot meet the perception range of the first device. In this case, the minimum value of the perception range can be compared with the minimum perception coverage of the pulse wave. If the minimum value of the perception range is greater than or equal to the minimum perception coverage of the pulse wave, it means that the coverage of the pulse wave can already meet the perception range of the first device. In this case, only the pulse wave needs to be used to meet the perception range of the first device. Therefore, the waveform type of the perception signal can be the second waveform type, which represents that the perception signal is entirely composed of pulse waves.

[0077] Step S403, when the maximum value of the perception range is greater than the maximum perception coverage range of the continuous wave, and the minimum value of the perception range is less than the minimum perception coverage range of the pulse wave, determine that the waveform type of the perception signal is the third waveform type; the third waveform type represents that the perception signal is composed of a continuous wave and a pulse wave.

[0078] If the maximum value of the perception range is greater than the maximum perception coverage range of the continuous wave, and the minimum value of the perception range is less than the minimum perception coverage range of the pulse wave, this indicates that neither the continuous wave nor the pulse wave can meet the perception range of the first device. Therefore, in this case, it is necessary to combine the continuous wave and the pulse wave, and the corresponding waveform type of the perception signal is the third waveform type. The second waveform type indicates that the perception signal can be composed of part of the continuous wave and part of the pulse wave.

[0079] In this embodiment, if the maximum value of the perception range is less than or equal to the maximum perception coverage range of the continuous wave, the waveform type of the perception signal can be set to the first waveform type that characterizes the entire continuous wave composition; if the minimum value of the perception range is greater than or equal to the minimum perception coverage range of the pulse wave, the waveform type of the perception signal can be set to the second waveform type that characterizes the entire pulse wave composition; and if the maximum value of the perception range is greater than the maximum perception coverage range of the continuous wave, and the minimum value is less than the minimum perception coverage range of the pulse wave, the waveform type of the perception signal is set to the third waveform type that characterizes the composition of the continuous wave and the pulse wave. In this way, the accuracy of waveform type screening can be improved.

[0080] Further, step S203 may further include: when the waveform type is the first waveform type, determining that the waveform arrangement mode of the perception signal is a single continuous wave arrangement mode; when the waveform arrangement mode is a single continuous wave arrangement mode, configuring a part of the signal arrangement position in the synaesthesia signal frame as a continuous wave to configure the waveform arrangement of the perception signal in the synaesthesia signal frame.

[0081] The waveform arrangement mode refers to the arrangement mode of the waveform of the perception signal in the synaesthesia signal frame. If the waveform type is the first waveform type, it means that the perception signal is composed entirely of continuous waves, so the corresponding waveform arrangement mode is a single continuous wave arrangement mode. In this case, the first device 101 can configure all the parts corresponding to the signal arrangement position in the synaesthesia signal frame as continuous waves. In this way, the waveform arrangement configuration of the perception signal in the synaesthesia signal frame can be completed. The specific configuration can be shown in Figure 5, where S represents the perception signal in a single synaesthesia signal frame, C represents a continuous wave, and L represents a continuous wave. s It indicates the perceived signal length.

[0082] In this embodiment, if the waveform type is the first waveform type, the part of the signal arrangement position in the synaesthesia signal frame can be configured as a continuous wave. In this way, the configuration of a single continuous wave can be completed, thereby improving the efficiency of the first waveform type configuration.

[0083] Similarly, step S203 may further include: when the waveform type is the second waveform type, determining that the waveform arrangement mode of the perception signal is a single pulse wave arrangement mode; when the waveform arrangement mode is a single pulse wave arrangement mode, configuring a part of the signal arrangement position in the synaesthesia signal frame as a pulse wave to configure the waveform arrangement of the perception signal in the synaesthesia signal frame.

[0084] Similarly, if the waveform type is the second waveform type, it means that the perception signal is composed entirely of pulse waves, so the corresponding waveform arrangement is a single pulse wave arrangement. In this case, the first device 101 can configure all the parts corresponding to the signal arrangement position in the synaesthesia signal frame as pulse waves. In this way, the waveform arrangement configuration of the perception signal in the synaesthesia signal frame can also be completed. The specific configuration can be shown in FIG6, where S represents the perception signal in a single synaesthesia signal frame, P represents a pulse wave, and L s It indicates the perceived signal length.

[0085] In this embodiment, if the waveform type is the second waveform type, the part of the signal arrangement position in the synaesthesia signal frame can be configured as a pulse wave. In this way, the configuration of a single pulse wave can be completed, thereby improving the efficiency of the second waveform type configuration.

[0086] In addition, step S203 may further include: when the waveform type is the third waveform type, according to the perception performance requirements, obtaining a target combination arrangement method from a plurality of combination arrangement methods as a waveform arrangement method of the perception signal; the plurality of combination arrangement methods correspond to different combination arrangement methods of continuous waves and pulse waves; and combining the continuous waves and the pulse waves for a part of the signal arrangement position in the synaesthesia signal frame according to the target combination arrangement method to configure the waveform arrangement of the perception signal in the synaesthesia signal frame.

[0087] If the waveform type is the third waveform type, that is, the perception signal needs to use both continuous waves and pulse waves, then the waveform arrangement of the perception signal can be a combination arrangement, and there are multiple combination arrangements, which can correspond to different combination arrangements of continuous waves and pulse waves. The target combination arrangement is the combination arrangement that is finally determined among the multiple combination arrangements, and the target combination arrangement can be determined according to the perception performance requirements.

[0088] Specifically, if the waveform type is the third waveform type, the first device 101 can determine the target combination arrangement method that matches the perception performance requirements from the pre-configured combination arrangement methods of multiple continuous waves and pulse waves, and then the part of the signal arrangement position in the synaesthesia signal frame can be configured with a combination of continuous waves and pulse waves according to the target combination arrangement method to complete the configuration of the waveform arrangement of the perception signal in the synaesthesia signal frame.

[0089] In this embodiment, if the waveform type is the third waveform type, the first device 101 can provide a variety of continuous wave and pulse wave combination arrangements, and can screen the target combination arrangement method according to the perception performance requirements. In this way, a variety of continuous wave and pulse wave combination configurations can be achieved, and the adaptability of the combination configuration method can be increased while improving the diversity of the combination configuration method of the continuous wave and the pulse wave.

[0090] Furthermore, the plurality of combination arrangement modes include: a first combination arrangement mode, a second combination arrangement mode and a third combination arrangement mode; as shown in FIG7 , the part of the signal arrangement position in the synaesthesia signal frame is combined and configured with a continuous wave and a pulse wave according to the target combination arrangement mode, which may further include:

[0091] Step S701 : when the target combination arrangement mode is the first combination arrangement mode, a portion of the signal arrangement position in each synaesthesia signal frame is configured as an alternating arrangement of continuous waves and pulse waves.

[0092] The first combination arrangement refers to the interlaced arrangement of continuous waves and pulse waves, that is, the continuous waves and pulse waves are sent interlaced in a single synaesthesia signal frame period. Therefore, in this case, the signal arrangement position in each synaesthesia signal frame can be configured as an interlaced arrangement of continuous waves and pulse waves. The specific configuration can be shown in FIG8 , where S represents the perception signal in a single synaesthesia signal frame, C represents the continuous wave, P represents the pulse wave, and L represents the continuous wave. s It indicates the length of the perceived signal. In the first combination arrangement, the continuous wave and the pulse wave are alternately configured.

[0093] Step S702, when the target combination arrangement mode is the second combination arrangement mode, the part of the signal arrangement position in each synaesthesia signal frame is configured as a mixed arrangement consisting of a continuous wave lasting a first signal length and a pulse wave lasting a second signal length; the sum of the first signal length and the second signal length is the perception signal length.

[0094] The second combination arrangement refers to a mixed arrangement of continuous waves and pulse waves, that is, in a single synaesthesia signal frame period, multiple continuous waves and multiple pulse waves are sent, wherein the total signal length of the multiple continuous waves is the first signal length, and the total signal length of the multiple pulse waves is the second signal length. Since the total signal length of the perception signal is the perception signal length, the sum of the first signal length and the second signal length is the perception signal length. Specifically, if the target combination arrangement is the second combination arrangement, the part of the signal arrangement position in each synaesthesia signal frame can be configured as a mixed arrangement of continuous waves and pulse waves, wherein the signal length of the continuous wave is the first signal length, and the signal length of the pulse wave is the second signal length, and the sum of the first signal length and the second signal length is the signal length of the perception signal. The specific configuration can be shown in Figure 9, where S represents the perception signal in a single synaesthesia signal frame, C represents a continuous wave, P represents a pulse wave, and L represents a continuous wave. s It represents the perceived signal length. In the second combination arrangement, the continuous wave and the pulse wave are mixed, wherein the pulse wave corresponds to m symbol lengths, that is, corresponds to the second signal length, and the continuous wave corresponds to n symbol lengths, corresponding to the first signal length.

[0095] Step S703, when the target combination arrangement mode is the third combination arrangement mode, the synaesthesia signal frame is divided into a first synaesthesia signal frame and a second synaesthesia signal frame; a portion of the signal arrangement position in each first synaesthesia signal frame is configured as a continuous wave, and a portion of the signal arrangement position in each second synaesthesia signal frame is configured as a pulse wave.

[0096] The third combination arrangement method refers to a method of combining and arranging two types of synaesthesia signal frames, and in a single synaesthesia signal frame, only one type of waveform arrangement is included, wherein the two types of synaesthesia signal frames can be respectively a first synaesthesia signal frame and a second synaesthesia signal frame, wherein the first synaesthesia signal frame is a synaesthesia signal frame in which the perception signal is configured as a continuous wave, and the second synaesthesia signal frame is a synaesthesia signal frame in which the perception signal is configured as a pulse wave. Specifically, if the target combination arrangement method is the third combination arrangement method, the synaesthesia signal frame can be divided into two types, namely a first synaesthesia signal frame and a second synaesthesia signal frame, wherein the portion of the signal arrangement position in the first synaesthesia signal frame is configured as a continuous wave, and the portion of the signal arrangement position in the first synaesthesia signal frame is configured as a pulse wave. The specific configuration can be shown in FIG. 10, wherein S represents the perception signal in a single synaesthesia signal frame, C represents a continuous wave, P represents a pulse wave, and L represents a pulse wave. sIt represents the length of the perception signal. In the third combination arrangement, the synaesthesia signal frames include two types, namely, a first synaesthesia signal frame in which the perception signal is configured as a continuous wave, and a second synaesthesia signal frame in which the perception signal is configured as a pulse wave. In different synaesthesia frame periods, X pulse wave perception frames and Y continuous wave perception frames can be sent in frames.

[0097] In this embodiment, the multiple combination arrangement methods may include: a first combination arrangement method, a second combination arrangement method and a third combination arrangement method, and the part of the signal arrangement position in the synaesthesia signal frame can be configured according to the first combination arrangement method, the second combination arrangement method and the third combination arrangement method. In this way, the diversity of the combination arrangement of perceptual signals in the synaesthesia signal frame can be improved.

[0098] In one embodiment, step S202 may further include: using the length of the perception signal to obtain a signal arrangement mode of the perception signal and the communication signal in the synaesthesia signal frame in the synaesthesia signal frame; the communication signal is used to communicate with the first device 101 and the second device 102; obtaining the starting signal position of the perception signal in the synaesthesia signal frame according to the signal arrangement mode, and determining the signal arrangement position of the perception signal in the synaesthesia signal frame using the starting signal position and the length of the perception signal.

[0099] The synaesthesia signal frame is composed of a perception signal and a communication signal, wherein the perception signal is used by the first device 101 to sense the second device 102 entering the perception range, and the communication signal can be used for the first device 101 to communicate with the second device 102, and the starting signal position refers to the starting position of the perception signal in the synaesthesia signal frame. In this embodiment, the signal arrangement position of the perception signal in the synaesthesia signal frame can be determined according to the starting position of the perception signal in the synaesthesia signal frame and the length of the perception signal, and the starting position of the perception signal is determined according to the signal arrangement method of the perception signal and the communication signal in the synaesthesia signal frame, and the above-mentioned signal arrangement method can be determined by the signal length of the perception signal.

[0100] Specifically, after the first device 101 obtains the signal length of the perception signal, it can use the perception signal length to determine the signal arrangement of the perception signal and the communication signal in the synaesthesia signal frame, thereby determining the starting position of the perception signal in the synaesthesia signal frame based on the above arrangement. Since the starting position of the perception signal in the synaesthesia signal frame and the signal length of the perception signal are determined, the signal arrangement position of the perception signal can be determined.

[0101] For example, the starting position of the perception signal in the synaesthesia signal frame is the 20th symbol position, and the perception signal length is 24 symbol positions, then the signal arrangement position of the perception signal in the synaesthesia signal frame is from the 20th symbol position to the 43rd symbol position.

[0102] In this embodiment, the first device 101 can determine the signal arrangement method of the perception signal and the communication signal according to the perception signal length, and then use the signal arrangement method to determine the starting signal position of the synaesthesia signal frame, so as to obtain the signal arrangement position in the synaesthesia signal frame by combining the starting signal position and the perception signal length. In this way, the accuracy of determining the signal arrangement position can be improved.

[0103] Further, as shown in FIG11 , obtaining the signal arrangement mode of the perception signal and the communication signal in the synaesthesia signal frame by using the perception signal length may further include:

[0104] Step S1101: Acquire the interval length of the protection interval between the communication signal and the perception signal according to the device parameters of the first device.

[0105] The guard interval refers to an interval used to isolate different types of signals. Since the communication signal and the perception signal may interfere with each other, in order to avoid the interference, a guard interval can usually be added between the communication signal and the perception signal, and the interval length is the length of the guard interval, and the interval length can be determined according to the device parameters of the first device 101. Specifically, the first device 101 can determine the interval length of the guard interval used to separate the communication signal and the perception signal according to its pre-set device parameters.

[0106] Step S1102, obtaining a target signal length that matches the perceived signal length from a plurality of preset signal lengths; the plurality of preset signal lengths are determined by different multiples of a reference signal length, the reference signal length being the length of a time slot that includes a time slot in a synaesthesia signal frame; the target signal length being a preset signal length that has the shortest signal length among the plurality of preset signal lengths, and whose signal length is greater than or equal to the perceived signal length.

[0107] Among them, the preset signal length refers to the signal length determined by different multiples of the reference signal length, and the reference signal length refers to the time slot length of the time slot contained in the synaesthesia signal frame. Taking the reference signal length as 14 symbol lengths as an example, the preset signal length can be 1 times, 2 times, and 3 times of the 14 symbol lengths, that is, 14 symbol lengths, 28 symbol lengths, and 42 symbol lengths, etc. respectively. The target signal length is the preset signal length with the smallest signal length among multiple preset signal lengths, and is greater than or equal to the perceived signal length. Taking the perceived signal length as 24 symbol lengths as an example, since multiple preset signal lengths are 14 symbol lengths, 28 symbol lengths, and 42 symbol lengths, etc., the preset signal length that is the smallest and greater than or equal to the perceived signal length is 28 symbol lengths. It can be seen that the target signal length that matches the perceived signal length refers to 28 symbol lengths.

[0108] Step S1103, obtaining a difference between the target signal length and the interval length of the guard interval, and determining a signal arrangement mode of the perception signal in the synaesthesia signal frame according to a size relationship between the perception signal length and the difference.

[0109] After obtaining the target signal length, the difference between the target signal length and the interval length of the protection interval can be calculated, and the size relationship between the perception signal length and the difference can be compared, so as to determine the signal arrangement mode of the perception signal in the synaesthesia signal frame according to the size relationship.

[0110] In this embodiment, the reference signal length can be obtained by using the time slot length of the time slot included in the synaesthesia signal frame, and multiple preset signal lengths can be obtained by using multiple different multiples of the reference signal length, so that the corresponding target signal length can be matched using the perception signal length, and the final signal arrangement method can be obtained using the target signal length and the interval length of the guard interval, which can improve the accuracy of obtaining the signal arrangement method.

[0111] Furthermore, the communication signal in the synaesthesia signal frame includes a downlink communication signal and an uplink communication signal; as shown in FIG12 , step S1103 may further include:

[0112] Step S1201: When the length of the perception signal is greater than or equal to the difference, determine that the signal arrangement is such that the perception signal is located before the downlink communication signal and after the uplink communication signal.

[0113] In this embodiment, the communication signal may include a downlink communication signal and an uplink communication signal. If the length of the perception signal is greater than or equal to the above difference, the signal arrangement is such that the perception signal is located before the downlink communication signal and the uplink communication signal. Taking the reference signal length as 14 symbol length as an example, if the following inequality is satisfied: 14n-Lgp ≤L s When ≤14n, L s Represents the perceived signal length, L gp Indicating the interval length of the protection interval, the perception signal is arranged before the downlink communication signal and after the uplink communication signal, that is, an arrangement of U after D before, wherein U represents the uplink communication signal and D represents the downlink communication signal.

[0114] Step S1202: When the perceived signal length is less than the difference value, detecting whether the first device 101 is subject to far-end interference;

[0115] Step S1203: When the first device 101 is not subjected to far-end interference, it is determined that the signal arrangement mode of the sensing signal is such that the sensing signal is located after the downlink communication signal and before the uplink communication signal.

[0116] If the perceived signal length is less than the difference, it does not satisfy 14n-L gp ≤L s When ≤14n, it is necessary to determine whether the first device 101 is subject to far-end interference, which refers to the far-end interference perceived by the communication. If it is not subject to far-end interference, the signal arrangement method of the perceived signal is set so that the perceived signal is located after the downlink communication signal and before the uplink communication signal, that is, the arrangement method of D after U before, where U represents the uplink communication signal and D represents the downlink communication signal.

[0117] Step S1204, when the first device is subject to far-end interference, determine that the perception signal is arranged in such a way that part of the perception signal is located after the downlink communication signal and before the uplink communication signal, and part of the perception signal is located before the downlink communication signal and after the uplink communication signal.

[0118] If the first device 101 is affected by far-end interference perceived by the communication pair, then an arrangement is adopted in which part of the perception signal is configured after the downlink communication signal D and before the uplink communication signal U, and part of the perception signal is configured before the downlink communication signal D and after the uplink communication signal U, that is, an arrangement of U after D before & D after U before is adopted, wherein U represents the uplink communication signal and D represents the downlink communication signal.

[0119] In this embodiment, the signal arrangement method to be used can be determined based on the relationship between the perceived signal length and the difference, and whether the first device 101 is subject to far-end interference. This method can improve the intelligence of determining the signal arrangement method.

[0120] Furthermore, if the synaesthesia signal processing method may also include: when the signal arrangement of the perception signal is to be located before the downlink communication signal and after the uplink communication signal, no protection interval is set between the perception signal and the communication signal; when the signal arrangement of the perception signal is to be located after the downlink communication signal and before the uplink communication signal, a protection interval is set between the perception signal and the communication signal.

[0121] In this embodiment, if the signal arrangement of the perception signal is to be located before the downlink communication signal and after the uplink communication signal, that is, the arrangement of U after D, due to limited mutual interference, it is not necessary to configure the protection interval GP between communication and perception at this time. Therefore, for the arrangement of U after D, it can be shown in Figure 13, where S represents the perception signal, U represents the uplink communication signal, D represents the downlink communication signal, and GP represents the protection interval.

[0122] If the perception signal is arranged after the downlink communication signal and before the uplink communication signal, that is, D after U before U, it is necessary to additionally configure a protection interval GP between the downlink communication and the perception. Therefore, for the arrangement of D after U before U, it can be shown as shown in Figure 14, where S represents the perception signal, U represents the uplink communication signal, D represents the downlink communication signal, and GP represents the protection interval.

[0123] Similarly, for the arrangement in which part of the perception signal is located after the downlink communication signal and before the uplink communication signal, and part of the perception signal is located before the downlink communication signal and after the uplink communication signal, that is, the arrangement of U after D and D after U before, for the part located after the downlink communication signal and before the uplink communication signal, that is, the part after U before D, it is not necessary to configure the protection interval GP between communication and perception, while for the part located before the downlink communication signal and after the uplink communication signal, it is necessary to configure the protection interval GP between communication and perception. Therefore, for the arrangement of U after D before & D after U before, it can be shown in Figure 15, where S represents the perception signal, U represents the uplink communication signal, D represents the downlink communication signal, and GP represents the protection interval.

[0124] In this embodiment, whether to set a guard interval between the perception signal and the communication signal can be determined according to the signal arrangement mode of the perception signal. In this way, the accuracy of the signal arrangement of the perception signal in the synaesthesia signal frame can be further improved.

[0125] In one embodiment, after step S203, the method may also include: when the second device 102 is connected to the first device 101, obtaining a perception information prompt mode pre-configured for the first device 101; when the perception information prompt mode is the first prompt mode, sending the perception signal prompt information to the second device 102 through RRC signaling; the perception signal prompt information is used to enable the second device to obtain the situation information of the perception signal in the synaesthesia signal frame; when the perception information prompt mode is the second prompt mode, not sending the perception signal prompt information to the second device 102.

[0126] The perception information prompting mode refers to the mode in which the first device 101 sends the perception signal prompting information. In this embodiment, the mode in which the first device 101 sends the perception signal prompting information can also be configured. If it is the first prompting mode, that is, the explicit indication mode, the perception signal prompting information can be sent through RRC signaling. The perception signal prompting information may include the length occupied by the perception signal, the starting and ending positions of the perception signal, the perception repetition period, and the configuration and arrangement of the perception waveform and other perception information. If it is the second prompting mode, that is, the implicit indication mode, the perception signal prompting information is not sent, but only the indication of the communication signal is sent. In this case, the communication scheduling is not performed at the location of the perception signal, and the specific situation of the perception signal is detected and detected by the terminal itself.

[0127] In this embodiment, the first device 101 may be configured with a perception information prompt mode, so as to determine whether to send the perception signal prompt information to the second device 102 according to the configured perception information prompt mode. In this way, the intelligence level of sending the perception signal prompt information can be improved.

[0128] In one embodiment, a method for configuring a synaesthesia frame structure is also provided. The method first proposes to use a single pulse wave or a single continuous wave or a combination of two waveforms for sensing coverage, and proposes a frame structure arrangement method for multiple sensing and communication resources, then defines multiple methods for arranging different sensing waveforms within the sensing resources, and finally proposes multiple methods for the network to indicate the terminal. The specific steps are as follows:

[0129] Step 1: First, determine the range R that needs to be sensed based on the sensing scenario min and R max . With the maximum perception coverage capability of continuous wave R c_max and the minimum perceptual coverage capability of the pulse wave R p_min Compare (bottleneck of both), and finally determine whether to use continuous wave alone for sensing, pulse wave alone for sensing, or continuous wave and pulse wave at the same time for sensing. If the maximum sensing range is within the continuous wave sensing range, R max ≤R c_max, a single continuous wave is used for sensing; if the minimum sensing range is larger than the pulse wave sensing blind area R min ≥R p_min , a single pulse wave is used for sensing; if the maximum sensing range exceeds the continuous wave sensing range R max >R c_max And the minimum sensing range is smaller than the pulse wave sensing blind area R min <R p_min , continuous wave and pulse wave are used simultaneously for perception, and the specific process is shown in Figure 16.

[0130] Step 2: According to the communication and perception performance requirements of the scenario, determine the time domain symbol length L that the perception resources need to occupy s . Communication and perception are configured in time division, and only one of the signals, communication or perception, is sent and received at one moment. In a synaesthesia frame period, the perception signal S can be configured before the downlink communication signal D and after the uplink communication signal U. Because the mutual interference is limited, there is no need to configure the protection interval GP between communication and perception at this time, as shown in Figure 13 (abbreviated as U after D before). The perception signal S can also be configured after the downlink communication signal D and before the uplink communication signal U. At this time, it is necessary to additionally configure the protection interval GP between the downlink communication and perception, as shown in Figure 14 (abbreviated as D after U before). The perception signal S can also be partially configured after the downlink communication signal D and before the uplink communication signal U, and partially configured before the downlink communication signal D and after the uplink communication signal U, as shown in Figure 15 (abbreviated as U after D before & D after U before).

[0131] The specific selection method is: define the protection interval GP length between downlink communication and perception as L gp If the total length of the perceived symbol is 14n-L gp ≤L s ≤14n, then U after D before can be adopted; if not, then D after U before can be adopted; if there is a large communication far-end interference to perception, then U after D before & D after U before can be adopted. The specific process is shown in Figure 17.

[0132] Step 3: After determining the sensing resource occupancy length and the time domain location, the sensing wave is specifically configured in combination with the sensing waveform selection in the first step. If a single continuous wave is used for sensing, all are configured as continuous waves, as shown in Figure 5, where C represents continuous waves; if a single pulse wave is used for sensing, all are configured as pulse waves, as shown in Figure 6, where P represents pulse waves; if continuous waves and pulse waves are used for sensing at the same time, there are three typical waveform arrangement configurations:

[0133] In a single synaesthesia frame period, the continuous wave and the pulse wave are sent alternately. The lengths of the pulse wave and the continuous wave can be different according to the perception requirements, and the total length satisfies L s , repeated within multiple synaesthesia frame periods, as shown in FIG8 ;

[0134] In a single synaesthesia frame period, continuous waves and pulse waves are mixed and sent, with m consecutive pulse waves and n consecutive continuous waves. The lengths of each wave can be different according to the perception requirements, and the total length satisfies L s , repeated within multiple synaesthesia frame periods, as shown in FIG9 ;

[0135] In a single synaesthesia frame period, only one kind of continuous wave or pulse wave is sent. In different synaesthesia frame periods, X pulse wave perception frames and Y continuous wave perception frames are sent in frames, and the total lengths occupied by each may not be equal according to the perception requirements, as shown in FIG10 .

[0136] The specific process is shown in Figure 18. It should be noted that in a single time slot, the above three typical waveform arrangements can also be used.

[0137] The perception and communication signals are configured based on the above frame structure. The perception signal can be sent or received on one or more symbols. A synaesthesia frame period consists of multiple time slots, so in a single time slot, there may be only communication signals, only perception signals, and perception signals and communication signals at the same time.

[0138] Step 4: Finally, the above network side configuration is used to indicate the corresponding perception signal information to the terminal, which can be divided into two indication methods: explicit and implicit. The specific process is shown in Figure 19.

[0139] Explicit indication method: Indicates the terminal perception information through RRC signaling on the network side, including the length occupied by the perception signal, the starting and ending positions of the perception signal, the perception repetition period, and the configuration and arrangement of the perception waveform.

[0140] Implicit indication method: The network side only sends communication signal instructions to the terminal, and no communication scheduling is performed at the location of the sensing signal. The specific situation of the sensing signal is detected and detected by the terminal itself.

[0141] In summary, the overall perception frame structure configuration is divided into four steps. The first three steps are the configuration of the frame structure on the network side, and the fourth step is the instruction to the terminal. The specific technical solution is as follows, as shown in Figure 20:

[0142] The sensing waveform mode to be adopted is determined based on the sensing coverage requirements and the coverage capabilities of the two sensing waveforms;

[0143] According to the communication and perception performance requirements, confirm the time domain symbol length and position required for the perception resources, and configure the time domain position structure of the perception and communication signals;

[0144] According to the sensing waveform and the sensing signal position, configure the specific arrangement of the sensing waveform;

[0145] Finally, the perception and communication signals are configured on the network side based on the above frame structure, and the perception signal information is indicated to the terminal.

[0146] Taking the millimeter wave frequency band as an example, the communication subcarrier spacing is configured to be 120kHz, the typical communication frame structure is DDDSU, and the corresponding period is 0.625ms.

[0147] Assuming that the perception range of the perception scene at this time is 10m to 1.5km, the maximum perception range exceeds the continuous wave perception range and the minimum perception range is smaller than the pulse wave perception blind spot. Therefore, continuous wave and pulse wave need to be used simultaneously for perception.

[0148] In order to meet the 3gpp drone intrusion detection perception index requirements, it is calculated that the perception resources need to occupy 24 symbols in the time domain. At this time, if the perception resources are arranged after U and before D, the last 4 symbols will remain in the second D time slot, but if the terminal does not support mini-slot scheduling at this time, there will be a waste of communication resources for the last 4 symbols. If the perception resources are arranged after D and before U, the resources of the second D time slot can still be scheduled to the terminal, and only 1 GP symbol is wasted for interference isolation between downlink communication and perception, which is less than the resource overhead after U and before D. Therefore, the perception resource arrangement is adopted after D and before U. Considering that the millimeter wave has a long air coverage propagation distance, the GP in the S subframe can be configured as 3 symbols, that is, the symbol ratio of downlink communication: GP: uplink communication in the S subframe is 9:3:2. The specific arrangement is shown in Figure 21.

[0149] According to the requirements of the coverage distance range, considering the alignment of the sensing symbol and the length of a single symbol under the communication frame structure, it can be calculated that a pulse wave needs to occupy 2 symbols and a continuous wave needs to occupy 1 symbol. Considering factors such as sensing resolution, accuracy, false alarm rate, missed detection rate, and refresh rate, consider adopting a mixed transmission mode of continuous waves and pulse waves. Configure 8 consecutive pulse waves and 8 continuous waves, and repeat them in each sensing frame period, as shown in Figure 22.

[0150] It should be understood that, although the various steps in the flowcharts involved in the above-mentioned embodiments are displayed in sequence according to the indication of the arrows, these steps are not necessarily executed in sequence according to the order indicated by the arrows. Unless there is a clear explanation in this article, the execution of these steps does not have a strict order restriction, and these steps can be executed in other orders. Moreover, at least a part of the steps in the flowcharts involved in the above-mentioned embodiments can include multiple steps or multiple stages, and these steps or stages are not necessarily executed at the same time, but can be executed at different times, and the execution order of these steps or stages is not necessarily to be carried out in sequence, but can be executed in turn or alternately with other steps or at least a part of the steps or stages in other steps.

[0151] Based on the same inventive concept, the embodiment of the present application also provides a synaesthesia signal processing device for implementing the synaesthesia signal processing method involved above. The implementation scheme for solving the problem provided by the device is similar to the implementation scheme recorded in the above method, so the specific limitations in the one or more synaesthesia signal processing device embodiments provided below can refer to the limitations of the synaesthesia signal processing method above, and will not be repeated here.

[0152] In one embodiment, as shown in FIG. 23 , a synaesthesia signal processing device is provided, comprising: a waveform type determination module 2301, a signal position determination module 2302, and a waveform arrangement configuration module 2303, wherein:

[0153] The waveform type determination module 2301 is used to determine the waveform type of the perception signal in the synaesthesia signal frame to be configured according to the perception range of the first device; the perception signal is used to sense the second device entering the perception range;
