Description

Technical Field

[0001] The present application relates to the field of communication technology, and in particular to a communication perception method and communication equipment. Background Art

[0002] In the future, the requirements for mobile communications in the fields of artificial intelligence (AI), immersive services, and digital twin services are getting higher and higher, and various complex application scenarios show that communication and perception are highly integrated. At the same time, as the communication frequency band develops towards high frequency bands, the overlap with the traditional radar perception band is becoming increasingly obvious. Implementing communication and perception functions in the same spectrum and the same hardware can help reduce equipment, cost, and volume.

[0003] In order to realize the communication perception function, the relevant technology usually uses radar and communication to share all hardware modules except the antenna in the traditional communication link. The solution is to move the transmitting antenna and the receiving antenna apart or use high isolation measures such as adding partitions to achieve transmission and reception isolation. This will bring the following problems: On the one hand, the antenna transmission and reception cannot share a pair of antennas. If the overall antenna volume remains unchanged, the corresponding transmitting or receiving antenna gain will be reduced by half, and the number of beamforming channels will also be reduced, affecting communication performance; on the other hand, if the transmitting antenna is kept unchanged compared to the previous communication antenna size, the overall antenna volume will double, directly increasing the volume and cost of the entire communication perception integrated base station.

[0019] In order to enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of this application.

[0020] The communication sensing method provided in the embodiment of the present application can be applied in a single base station architecture with integrated communication and sensing. Communication and (radar) sensing work in time-sharing mode. By introducing flexible antenna grouping technology, additional sensing functions can be added while keeping the hardware of the communication equipment unchanged. Antenna grouping technology supports all antenna channels of a communication time domain unit (such as a communication time slot or symbol) to participate in communication beamforming; some antennas of a radar sensing time domain unit (such as a sensing time slot or symbol) transmit sensing signals, and some antennas receive sensing signals, solving the problem that the communication sensing scheme in the related technology affects the communication performance or increases the size and cost of the antenna.

[0021] Optionally, in the communication perception method provided in the embodiment of the present application, a flexible antenna grouping technology is adopted, and the selection of transmitting and receiving antenna groups can be adaptively completed according to the requirements of the perception scenario. For scenarios with low perception performance requirements, fewer antenna channels can be selected to achieve the requirement of reducing power consumption; for scenarios with high perception performance requirements, antenna groups with a higher number of antenna channels are adaptively selected to prioritize perception performance. This will be explained in detail below in conjunction with specific embodiments.

[0022] Figure 1 A flow chart of a communication perception method provided in an embodiment of the present application is shown. The method can be executed by a communication device. In other words, the method can be executed by software or hardware installed in the communication device. Figure 1 As shown, the method may include the following steps.

[0023] S102: Acquire perception signaling.

[0024] The perception signaling may be used to indicate perception sequence data, which may be used to send or receive a perception signal. The perception signaling may also carry information other than the perception sequence data, for example, a perception performance requirement, which is used to assist in determining the first group of antennas and the second group of antennas.

[0025] S104: Determine a first group of antennas and a second group of antennas in an antenna array based on the perception signaling; wherein, in a perception time domain unit, the first group of antennas is used to send perception signals, and the second group of antennas is used to receive reflected perception signals; and in a communication time domain unit, all antennas in the antenna array are used for communication beamforming.

[0026] It can be understood that the antenna array generally includes multiple antenna units (antennas for short), and the first group of antennas determined in this step may include multiple antennas; the second group of antennas may also include multiple antennas. The isolation between the antennas in the first group of antennas and the antennas in the second group of antennas may meet a predefined isolation index value, for example, greater than or equal to a predefined isolation index value, thereby minimizing the self-interference of the transceiver of the sensing signal in the sensing time domain unit.

[0027] Generally, one antenna corresponds to one antenna channel. Therefore, the determination of the first group of antennas and the second group of antennas in the antenna array described in this embodiment may also be described as determining the first group of antenna channels and the second group of antenna channels.

[0028] The perception time domain unit mentioned in this embodiment may be a time domain unit for sending and receiving perception signals, and the time domain unit may be a time slot or a symbol, etc. The communication time domain unit mentioned in this embodiment may be a time domain unit for implementing uplink and downlink communications, and the time domain unit may also be a time slot or a symbol, etc.

[0029] Optionally, S104 may also include the following steps: in the perception time domain unit, controlling the first group of antennas to send perception signals, and controlling the second group of antennas to receive the reflected perception signals, thereby realizing the perception function; in the communication time domain unit, controlling all antennas in the antenna array to perform communication beamforming, thereby realizing high-gain communication performance.

[0030] The communication sensing method provided in the embodiment of the present application can determine the first group of antennas and the second group of antennas in the antenna array based on the sensing signaling, the first group of antennas is used to send the sensing signal in the sensing time domain unit, and the second group of antennas is used to receive the reflected sensing signal in the sensing time domain unit; in the communication time domain unit, all antennas in the antenna array are used for communication beamforming. Due to the use of antenna grouping technology, compared with the scheme of moving the transmitting antenna and the receiving antenna apart or adding a partition, the communication performance can be improved and the problem of increasing the antenna volume and cost can be avoided.

[0031] The communication sensing method provided in the embodiment of the present application does not need to add sensing hardware circuits, and can add base station sensing functions on the basis of keeping the existing communication simulation hardware unchanged; in addition, there is no need to add additional self-interference elimination design, and radar transmission and reception self-interference elimination can be achieved only through antenna grouping transmission and reception channel selection; in addition, it does not affect the multi-channel antenna beamforming function of the communication time domain unit, and has no effect on the operation of the communication time domain unit.

[0032] Optionally, the perception signaling obtained in S102 can also be used to indicate perception performance requirements, and determining the first group of antennas and the second group of antennas in the antenna array based on the perception signaling in S10 includes: determining a target antenna profile from multiple sets of antenna profiles based on the perception performance requirements; determining the first group of antennas and the second group of antennas in the antenna array based on the target antenna profile; wherein, among the multiple sets of antenna profiles, at least two sets of the antenna profiles correspond to different perception performance requirements.

[0033] In this embodiment, the perception performance requirements can be reflected by at least one of the following: angle measurement accuracy, distance measurement accuracy, speed measurement accuracy, coverage distance, constant false alarm rate, etc., wherein different perception performance requirements can correspond to different application scenarios, and the different perception performance requirements mentioned here can refer to different levels (or sizes) of perception performance requirements.

[0034] For example, in the drone intrusion monitoring scenario, since it is only necessary to monitor whether there are drones in the designated area, the required perception performance requirements are not high, such as the ranging accuracy and speed measurement accuracy can be lower than a certain threshold; while for the lane and traffic flow monitoring scenario, since it is necessary to accurately locate vehicles in different lanes, the accuracy and resolution performance requirements are very high, so the required perception performance requirements are relatively high, such as the ranging accuracy and speed measurement accuracy need to be higher than a certain threshold.

[0035] For example, the perception performance requirements are divided into three levels: high, medium and low, which correspond to the first perception scenario, the second perception scenario and the third perception scenario, respectively. Among them, the first perception scenario has the highest perception performance requirement, and accordingly the required number of transmitting antennas (i.e., the number of antennas in the first group of antennas) and the number of receiving antennas (i.e., the number of antennas in the second group of antennas) are the highest, which is conducive to ensuring high-performance perception; the third perception scenario has the lowest perception performance requirement, and accordingly the required number of transmitting antennas and the number of receiving antennas are the lowest, which is conducive to reducing power consumption; the second perception scenario has an average perception performance requirement, and accordingly the required number of transmitting antennas and the number of receiving antennas are between the above two, which is convenient for maintaining a balance between low power consumption and high perception performance.

[0036] This embodiment can flexibly select antenna groupings. Different antenna groupings can be configured for different perception performance scenarios. Adaptive antenna grouping selection helps to reduce power consumption and can flexibly switch between low-power consumption scenarios and high-perception performance scenarios.

[0037] Optionally, under different perceived performance requirements: the number of antennas in the first antenna group in the multiple sets of antenna configuration files is different, and the number of antennas in the second antenna group in the multiple sets of antenna configuration files is different.

[0038] Optionally, the level of the perception performance requirement is positively correlated with the number of antennas in the first group of antennas, that is, the higher the perception performance requirement, the more antennas in the first group of antennas, which is convenient for improving the perception performance; conversely, the lower the perception performance requirement, the fewer antennas in the first group of antennas, which is convenient for reducing power consumption. Similarly, the level of the perception performance requirement is positively correlated with the number of antennas in the second group of antennas, that is, the higher the perception performance requirement, the more antennas in the second group of antennas, which is convenient for improving the perception performance; conversely, the lower the perception performance requirement, the fewer antennas in the second group of antennas, which is convenient for reducing power consumption.

[0039] The methods provided in the above embodiments may further include the following steps: generating the multiple sets of antenna configuration files based on at least one of the following:

[0040] 1) Isolation between different antennas in the antenna array.

[0041] 2) The following contents are respectively required by the plurality of different perception performance requirements: the number of antennas in the first antenna group and the number of antennas in the second antenna group.

[0042] Based on the above embodiments, the perception signaling can also be used to indicate perception sequence data. The method also includes: in the perception time domain unit, based on the perception sequence data, using the first group of antennas to send the perception signal, and using the second group of antennas to receive the reflected perception signal.

[0043] Corresponding to the above method embodiments, the present application also provides an example of a communication device (such as a base station), which includes an antenna array, and the antenna array supports being divided into a first group of antennas and a second group of antennas; wherein, in the perception time domain unit, the first group of antennas is used to send perception signals, and the second group of antennas is used to receive the reflected perception signals; in the communication time domain unit, all antennas in the antenna array are used for communication beamforming.

[0044] In the embodiment of the present application, the antenna array can be divided into a first group of antennas and a second group of antennas, the first group of antennas is used to send perception signals in the perception time domain unit, and the second group of antennas is used to receive reflected perception signals in the perception time domain unit; in the communication time domain unit, all antennas in the antenna array are used for communication beamforming. Due to the use of antenna grouping technology, compared with the solution of moving the transmitting antenna and the receiving antenna apart or adding a partition, the communication performance can be improved and the problem of increasing the antenna volume and cost can be avoided.

[0045] Optionally, the communication device further includes a storage module, which stores multiple sets of antenna configuration files, at least two sets of antenna configuration files correspond to different perceived performance requirements, and the perceived performance requirements are used to determine a target antenna configuration file from the multiple sets of antenna configuration files.

[0046] Optionally, the perceived performance requirement is positively correlated with the number of antennas in the first group of antennas, and / or the perceived performance requirement is positively correlated with the number of antennas in the second group of antennas.

[0047] To explain in detail the communication perception method and communication device provided in the embodiments of the present application, the following will be described in conjunction with specific embodiments.

[0048] The communication sensing method provided in the embodiment of the present application involves a base station architecture such as Figure 2 and Figure 3 As shown, two antennas for transmission and reception are no longer used. Instead, antenna grouping technology is used to select the transmission and reception channels of the antenna array in the original communication large array, which specifically includes the following modules:

[0049] The communication and radar signal processing module can be divided into: a downlink orthogonal frequency division multiplexing (OFDM) signal processing or radar signal processing module 201 and an uplink OFDM signal processing or radar signal processing module 202 .

[0050] The communication and radar common devices and modules mainly include: TDD switching frame 203, TDD switching frame 203 mainly includes TDD transmission switching frame 203-1 and TDD reception switching frame 203-2; shared transmission digital-to-analog conversion module 204 ( Figure 2 TX DAC in the transmitter); transmit power amplifier 205 ( Figure 2 PA in); circulator 206; antenna array 207 ( Figure 2 antenna shown in FIG); receiving low noise amplifier 208 ( Figure 2 LNA in); receiving analog-to-digital conversion module 209 ( Figure 2RX ADC in the ADC).

[0051] Figure 3 Mainly for Figure 2 The antenna array 207 in FIG. 2 is used to illustrate that the antenna array 207 can be divided into two parts, and a part of the channels is selected to form a radar sensing transmitting antenna 301, corresponding to the first group of antennas in the above embodiment; another part of the channels is selected to form a radar sensing receiving antenna 302, corresponding to the second group of antennas in the above embodiment. The selection of the transmitting and receiving channels can be determined according to the sensing performance requirements and the isolation between the antenna channels. Figure 3 The number of antennas in the antenna group shown in the dashed box is for illustration only, and the number of antennas is not specifically limited.

[0052] In a single base station with integrated communication and perception, the communication and perception functions are distinguished by working in different time slots. Figure 4 As shown, consistent with the traditional time division duplexing (TDD) communication system, the base station transmits and receives data by different time slots. The base station uses D time slot 401 for downlink communication and U time slot 403 for uplink communication. The D time slot 401 and the U time slot 403 correspond to the communication time domain unit of the previous embodiment. The antenna array can be fully reused in the communication time slot to maximize the communication performance.

[0053] By additionally adding or modifying the original time slot, the X time slot 402 is used for sensing, and the X time slot 402 corresponds to the sensing time domain unit in the above embodiment.

[0054] D time slot 401 is used for downlink communication of the base station, and TDD transmission switching group frame 203-1 is connected to the communication processing module in the downlink OFDM signal processing or radar signal processing module 201. The selection of the downlink OFDM signal processing module and the radar signal generating module (or radar signal processing module) is distinguished by software control, and the TDD reception switching group frame 203-2 is not connected. The communication processing module in the downlink OFDM signal processing or radar signal processing module 201 sends a baseband signal to the transmission digital-to-analog conversion module 204, and the signal is converted from a baseband digital signal to an analog signal. The analog signal is amplified to the rated transmission power by the transmission power amplifier 205, passes through the circulator 206, and is finally sent to the UE by the antenna array 207.

[0055] U time slot 403 is used as the base station communication uplink, TDD transmission switching frame 203-1 is not connected, TDD reception switching frame 203-2 is connected to the communication processing module in the uplink OFDM signal processing or radar signal processing module 202, and the selection of the uplink OFDM signal processing module and the radar signal processing module 202 is distinguished by software control. The communication analog signal sent by the UE is received via the antenna array 207 and enters the low noise amplifier 208 of the receiving link. Next, the analog signal is converted into a digital signal through the receiving analog-to-digital conversion module 209, and the digital signal enters the communication processing module in the uplink OFDM signal processing or radar signal processing module 202 to complete communication functions such as signal demodulation.

[0056] The X time slot 402 is used for base station sensing. The base station sends a sensing signal to the object to be measured, collects the echo reflected by the object to be measured, and studies the autocorrelation characteristics of the echo and the transmitted waveform to complete the sensing, which can be information such as distance, speed, angle, etc.

[0057] In the X time slot 402, the TDD transmission switching subframe 203-1 is connected to the radar signal generating module in the downlink OFDM signal processing or radar signal processing module 201, and the TDD reception switching subframe 203-2 is connected to the radar signal processing module in the uplink OFDM signal processing or radar signal processing module 202. The radar signal generating module in the downlink OFDM signal processing or radar signal processing module 201 sends a radar frequency modulated continuous wave (FMCW), linear frequency modulation (LFM) or OFDM signal, and the digital signal is converted into an analog signal via the transmission digital-to-analog conversion module 204, and the analog signal is amplified to the rated transmission power via the transmission power amplifier 205, and finally sent to the object to be measured by the radar sensing transmitting antenna 301 on the antenna array 207. The echo signal reflected back by the object to be measured is received by the radar sensing receiving antenna 302 on the communication antenna array 207, and enters the low noise amplifier 208 of the receiving link. Next, the analog signal is converted into a digital signal through the receiving analog-to-digital conversion module 209, and the digital signal enters the radar signal processing module in the uplink OFDM signal processing or radar signal processing module 202, and pulse compression, constant false alarm rate (CFAR) judgment and multiple fast Fourier transform (FFT) and other processing processes are completed in the radar signal processing module. Finally, the distance, speed or angle estimation analysis is completed, and after all the analysis is completed, the visualization display is completed through the post-processing.

[0058] It should be noted that in the X-slot 402 base station perception, the radar transmission signal will enter the receiver in two parts, one part will be propagated to the target to be measured in a normal way, and the target to be measured will reflect the echo to the receiver; the other part will be directly radiated or leaked into the receiver through space. This part of energy is called radar transmission interference. Usually, the interference level is high, which will cause the receiver to saturate and fail to work, thereby affecting the radar receiving the echo signal. In order to solve this interference problem, the traditional solution mainly lies in adding analog offset, digital offset, and spatial offset. Analog offset requires the addition of additional delay amplitude modulation devices, which increases the hardware complexity and cost. Digital offset requires additional computing resources, increases the power consumption of the chip and the complexity of the algorithm. Spatial offset is usually solved by pulling two antennas apart. The transmitting antenna and the receiving antenna achieve a certain electrical length distinction by pulling the distance apart or adding isolation measures such as choke slots, improving isolation, and reducing the leakage signal level so that it does not saturate the receiver. However, the separation of the two antennas affects the communication time slot. The isolation at a certain distance will first lead to the multi-channel beamforming of the antenna. The antenna cannot be reused in the transmit and receive time slots, and the gain and other indicators will deteriorate, which will eventually lead to a decrease in the coverage distance and beam scanning capability of the AAU. In addition, in order to ensure the same antenna gain, the transmit and receive antennas need to be expanded, but this will increase the windward surface, the volume, and the cost.

[0059] Based on this problem, the embodiment of the present application creatively proposes the application of antenna grouping technology in a single base station with integrated communication and perception. In the communication time slot, the antenna array 207 does not make any distinction between transmission and reception. The communication transmission and reception time slots are the same as the traditional ones, and the entire antenna surface can be shared. The gain, beamforming and corresponding scanning capabilities remain unchanged. In the perception time slot, the antenna array 207 is grouped, and the antennas that meet the isolation index requirements are divided into transmission and reception channels to ensure that the perception function is realized without affecting the self-interference of the radar transmission signal.

[0060] In addition, future perception scenarios will be diverse, including but not limited to smart drone low-altitude security, smart transportation, smart weather monitoring, etc. The perception performance requirements of different scenarios are different. The integrated communication and perception single base station involved in the embodiment of the present application can realize intelligent configuration. After the product is prepared, the isolation capability between each antenna is introduced into the device configuration, and the transmitting and receiving antenna grouping selection can be adaptively completed according to the requirements of the perception scenario.

[0061] like Figure 5As shown, for scenarios with low perception performance requirements, such as drone 504 monitoring and other scenarios, only target intrusion identification is performed, and the requirements for performance such as accuracy and resolution are not high. The base station can select fewer transmitting antennas 502 (corresponding to the first group of antennas in the previous embodiment) and receiving antennas 503 (corresponding to the second group of antennas in the previous embodiment) that meet the isolation requirements. The perception signal is transmitted from the perception RF link & digital processing module 501 to the transmitting antenna 502, and the echo signal reflected by the drone 504 enters the receiving antenna 503, and then is transmitted to the perception RF link & digital processing module 501 to realize the full perception process. The selection of fewer transmitting and receiving channels can significantly reduce power consumption and meet the low-carbon and green environmental protection requirements.

[0062] like Figure 6 As shown, for scenarios with high perception performance requirements, such as lane & traffic flow 604 monitoring, it is necessary to accurately locate vehicles in different lanes, and the accuracy and resolution performance requirements are very high. The base station needs to select more transmitting antennas 602 (corresponding to the first group of antennas in the previous embodiment) and receiving antennas 603 (corresponding to the second group of antennas in the previous embodiment) that meet the isolation requirements. The perception signal is transmitted from the perception RF link & digital processing module 601 to the transmitting antenna 602, and the echo signal reflected by the vehicle 604 enters the receiving antenna 603, and then is transmitted to the perception RF link & digital processing module 601 to realize the full perception process. Higher performance requirements can adaptively configure more antennas to meet the requirements of giving priority to high performance.

[0063] For the entire flexible adaptive grouping selection, please refer to Figure 7 As shown. The base station receives the demand for external perception services and passes the demand to the perception network element. The perception network element passes the perception scene information & tasks to the BBU baseband processing unit. For example, when it receives the perception service demand for drone intrusion monitoring, the core perception network element passes the demand and initiates the perception task to the BBU baseband processing unit. The BBU baseband processing unit sends the perception signaling and perception sequence data to the AAU and RRU RF processing unit. It should be noted here that the AAU & RRU RF processing unit internally stores multiple sets of configuration files for transmit and receive antennas with different isolation levels. The isolation between different antennas in this configuration file is measured through the OTA test of the antenna in production. The isolation is applied to the design of different scenarios, and finally multiple sets of configuration files are generated based on the design results. Multiple sets of configuration files can cover basic synaesthesia scenarios, including smart transportation, smart low altitude, smart life and other scenarios. The scenarios are not limited to Figure 7Description in . For smart transportation, basic profiles (high-speed rail & intersection intrusion detection) and high-performance profiles (unmanned driving, etc.) are distinguished according to the difference in isolation indicators. After the AAU&RRU RF processing unit receives the perception scenario signaling and perception sequence data transmitted by the BBU, it loads the internally stored configuration file, and the configuration file information is passed to the intermediate frequency processing chip inside the AAU&RRU. The intermediate frequency processing chip initiates channel-level interrupt control according to the determined configuration file, and finally the perception signal is sent to the target to be perceived through the interrupt-controlled RF channel and antenna, and finally the target to be perceived is transmitted back to the base station. Based on this, the isolation and RF channels can be flexibly configured according to the scenario, so as to realize flexible configuration options of a small number of channel transmission and reception in low-requirement and low-power consumption scenarios and a large number of channel transmission and reception in high-performance scenarios.

[0064] In general, different from the traditional integrated communication and perception base station, the embodiment of the present application creatively proposes a flexible antenna grouping technology, which can ensure that the existing communication hardware architecture remains unchanged, while adding additional perception functions, thereby achieving rapid deployment and cost reduction.
