[0041] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be embodied in many forms and should not be construed as limited to the examples set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete and will fully convey the concepts of the example embodiments to those skilled in the art. The described features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

[0042] In addition, the accompanying drawings are merely schematic illustrations of the present disclosure and are not necessarily drawn to scale. Identical reference numerals in the figures denote identical or similar parts, and thus repetitive descriptions thereof will be omitted. Some of the block diagrams shown in the accompanying drawings are functional entities that do not necessarily correspond to physically or logically separate entities. These functional entities may be implemented in software, in one or more hardware modules or integrated circuits, or in different networks and / or processor devices and / or microcontroller devices.

[0043] The solution provided in this disclosure is a method, device, and system for integrating communication and perception based on hybrid precoding and hybrid beamforming. By designing the perception signal and the integrated communication system, the perception beam is blended into the communication beam to achieve hybrid multi-user multiple-input multiple-output (MU-MIMO). To facilitate understanding, several terms involved in this application are first explained below.

[0044] Mixed Precoding (MP): The communication signal to be sent is mixed with the perception signal to obtain a mixed signal, and then the mixed signal is precoded.

[0045] Mixed Beam Forming (MBF): The communication signal to be transmitted is mixed with the perception signal to obtain a mixed signal. The mixed signal is then subjected to hybrid beam forming to flexibly adjust the power and weight of the communication signal and the perception signal to meet the beam width and gain requirements of each signal.

[0046] Radar signals: including swept cosine (Chirp) signals, Orthogonal Frequency Division Multiplexing-Swept Cosine signals (OFDM-Chirp) and continuous wave signals.

[0047] Orthogonal Frequency Division Multiplexing-Swept Cosine Signal (OFDM-Chirp) is a modulation scheme that combines Orthogonal Frequency Division Multiplexing (OFDM) and swept frequency (chirp) technology. In OFDM-Chirp, a swept cosine signal is used as the modulating signal for the OFDM symbols. A swept cosine signal has a linear frequency variation, where its frequency increases or decreases linearly over time. In OFDM-Chirp, a swept cosine signal is superimposed on each subcarrier of the OFDM symbol, thus achieving frequency variation in the frequency domain.

[0048] In some embodiments of the present disclosure, the modulation process of OFDM-Chirp may include: 1) Subcarrier generation: First, according to the principle of OFDM, a set of orthogonal subcarriers is generated. These subcarriers are evenly distributed in the frequency domain and are used to carry data. 2) Swept cosine signal generation: Generate a swept cosine signal whose frequency changes linearly with time. The swept cosine signal can be generated by a linear frequency modulator or other sweeping technology. 3) Modulation: Modulate the swept cosine signal with each subcarrier, that is, map the frequency change of the swept cosine signal to each subcarrier. In this way, each subcarrier has a frequency that changes with time. 4) Parallel transmission: The modulated subcarriers are transmitted in parallel, and each subcarrier carries a data stream. Since the subcarriers have different frequencies, they will not interfere with each other.

[0049] Multi-User Multiple-Input Multiple-Output (MU-MIMO) is a spatial division multiplexing technology. In MU-MIMO, a base station sends independent data streams to multiple user terminals simultaneously, using multiple antennas for transmission, enabling parallel data transmission among multiple users.

[0050] It should be noted that the disclosed method can be widely used in target object detection and positioning tasks in fields such as autonomous driving, intelligent transportation, drones, and security.

[0051] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the number of the technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. Throughout the description of this disclosure, "plurality" means at least two, such as two, three, etc., unless otherwise specifically defined.

[0052] In response to the technical problems existing in the above-mentioned related technologies, the embodiments of the present disclosure provide a communication perception method, device, system, electronic device and computer-readable storage medium to solve at least one or all of the above-mentioned technical problems.

[0053] FIG1 is a flow chart of a communication perception method according to an embodiment of the present disclosure. As shown in FIG1 , the method 100 may include the following steps:

[0054] In step S110 , a target wide beam where the target object is located is roughly detected using a plurality of downlink communication symbols in a specific time slot of the communication signal.

[0055] In some embodiments of the present disclosure, the specific time slot may be an S time slot.

[0056] Among them, the target objects to be detected can be vehicles, drones, airplanes, ships, etc.

[0057] For example, Figure 2 illustrates a communication signal diagram using a 2.5ms period with one S-slot per period, where the communication signal stream 210 includes a frame structure of 10 DL(D):2 GP:2 UL(U). In Figure 2 , the first eight downlink communication symbols of the communication signal stream (i.e., the data stream of the communication signal) 210 are used for both communication and perception services, performing coarse detection 220 to initially sense the target wide beam where the target object is located.

[0058] In step S120, if there is a target wide beam, a perception transmission symbol is multiplexed on the downlink communication symbol before the guard interval symbol in a specific time slot to transmit a mixed data stream of a communication signal data stream and a perception signal data stream obtained based on hybrid precoding and hybrid beamforming.

[0059] The number of downlink communication symbols can be adjusted and configured to any number according to the transmission duration of the perception service. For example, on two downlink communication symbols in the communication signal stream 230 in FIG2 , the perception transmission symbol PT is multiplexed to transmit a mixed data stream of the communication signal data stream and the perception signal data stream.

[0060] The communication signal is an Orthogonal Frequency Division Multiplexing (OFDM) signal.

[0061] Among them, the sensing signal is a radar signal.

[0062] In some embodiments of the present disclosure, if there is no target wide beam, there is no need to send the sensing signal.

[0063] In step S130, sensing reception is performed using sensing reception symbols during the guard interval symbol in the specific time slot to sense the target narrow beam where the target object is located.

[0064] In some embodiments of the present disclosure, the number of guard interval symbols can be adjusted and configured to any number within a range of 2 to 14 based on the reception duration of the sensing service. For example, sensing reception symbols PX are used on two guard interval symbols GP of the communication signal stream 210 in FIG2 to perform sensing reception and sense the target narrow beam where the target object is located.

[0065] The method of the embodiment of the present disclosure realizes coarse detection of perception services through downlink communication symbols in a specific time slot of the communication signal, preliminarily perceives the perceived object (such as the target object) on a certain communication signal stream (wide) beam, improves the perception efficiency, and provides a method and process that meets the needs of perception services under different accuracies.

[0066] Furthermore, the method of the embodiment of the present disclosure implements hybrid preprocessing and hybrid beamforming of perception beams and communication beams, realizes hybrid beam uniformity processing, and saves processing, maintenance and optimization costs.

[0067] Furthermore, the method of the embodiment of the present disclosure improves the utilization rate of wireless resources, is conducive to providing perception services without reducing the uplink and downlink communication rates and capacity and user experience, is conducive to the deployment and implementation of perception capability systems in communication networks, and has broad application prospects and promotion value.

[0068] Furthermore, the method of the embodiment of the present disclosure provides perception capabilities under full-area coverage without almost degrading the performance of the communication network, supplies additional perception services at a relatively low cost, saves deployment costs, and facilitates the provision of value-added perception services.

[0069] In some embodiments of the present disclosure, step S110 may also be, for example, the coarse detection scenario 300 shown in FIG3 . The first multiple downlink communication symbols (D) in a specific time slot (e.g., the S time slot) of the communication signal use an OFDM waveform to perform communication services while performing coarse detection of sensing services, thereby preliminarily sensing that the sensed object is located in a wide beam of a data stream of one (or several) communication signals.

[0070] In some embodiments of the present disclosure, the wide beams of the data streams of multiple communication signals can be coarsely detected simultaneously or coarsely detected in a polling time-sharing manner. As shown in Figure 3, on the communication wide beam i, the communication wide beam is indexed as Com_Beam_i, and the other communication wide beams Com_Beam_1 to Com_Beam_n (except the communication wide beam i) are used for communication services. The communication wide beam used for communication services can be called a communication service beam, and the communication wide beam used for perception services can be called a perception service beam. Generally, the perception service beam does not overlap with the communication service beam direction (as shown in Figure 3, one is facing the sky for perception detection of target objects 1 to target objects m, and the others are facing the ground for communication with ordinary terminals UE1 to UEn). However, in special cases, that is, when the perception service beam overlaps with the communication service beam direction, they can be staggered in time, with the beam used for perception coarse detection taking priority or the beam used for communication services taking priority. As a coarse detection of perception services with low precision requirements, it can also serve as the basis for fine detection of perception services with high precision requirements, thereby improving detection efficiency and meeting the needs of perception services under different precisions.

[0071] As shown in Figure 3, when target objects 1 to m encounter beam Com_Beam_i, a reflected echo is generated, which in turn causes co-channel interference between the reflected echo and the transmitted signal. Therefore, in some embodiments of the present disclosure, the method of the embodiments of the present disclosure may further include: during coarse detection, using the communication signal to cancel the reflected echo from the target object. For example, the transmitted communication signal is adjusted to have the same delay, amplitude, and phase as the co-channel interference of the reflected echo, and then the two signals are exactly canceled after passing through the adder. This suppresses the interference of the transmission on the co-channel reception and improves the coarse detection performance.

[0072] In some embodiments of the present disclosure, step S120 may further include: mixing the data stream of the communication signal using an orthogonal frequency division multiplexing signal and the data stream of the perception signal using a radar signal to generate MU-MIMO.

[0073] In the scenario 400 shown in FIG4 , on the downlink communication symbol D preceding the guard interval symbol GP in a specific time slot, the perception transmission symbol PT is multiplexed to transmit a mixed data stream of a communication signal (OFDM) and a perception signal (radar signal) obtained based on hybrid precoding and hybrid beamforming. OFDM signals and radar signals are processed using hybrid precoding and hybrid digital beamforming to implement hybrid MU-MIMO (spatial division multiplexing). This involves hybrid MU-MIMO of (n-1) wide communication beams (Com_Beam_1 to Com_Beam_n, excluding i, where n is a positive integer greater than or equal to 1 and i is a positive integer greater than or equal to 1 and less than n) with one wide communication beam (Com_Beam_i) and m narrow perception service beams (PT_Beam_1 to PT_Beam_m, corresponding to targets 1 to m, respectively). This results in a total of (n-1) wide beams and m narrow beams, or n-1+m hybrid beams. m is a positive integer greater than or equal to 1.

[0074] In the method of the disclosed embodiment, in MU-MIMO, a base station simultaneously sends independent data streams to multiple user terminals, using multiple antennas for transmission, thereby achieving parallel data transmission between multiple users. This allows multiple users to communicate data simultaneously on the same spectrum resources, improving spectrum utilization.

[0075] In addition, MU-MIMO also uses spatial diversity technology to transmit different data streams to different users in a spatially separated manner through the construction of antenna arrays and beamforming methods, eliminating interference between users and improving the capacity and performance of the communication system.

[0076] In some embodiments of the present disclosure, the radar signal is an orthogonal frequency division multiplexed swept cosine signal (OFDM-Chirp signal). Using OFDM-Chirp, high spectral efficiency is achieved in the frequency domain, and multiple data streams can be transmitted simultaneously. In addition, due to the introduction of the swept cosine signal, OFDM-Chirp also has the ability to resist multipath interference and can cope with complex wireless channel environments. Furthermore, by combining the characteristics of the swept cosine signal Chirp with the high spectral efficiency of OFDM, high-efficiency transmission in the frequency domain and time domain is achieved.

[0077] In some embodiments of the present disclosure, step S130 may also be, for example, the scenario 500 shown in FIG5 . In FIG5 , during the guard interval symbol GP in a specific time slot, the sensing reception symbol PX is used to perform sensing reception to sense the direction of the target narrow beams PX_Beam_1 to PX_Beam_m where the target objects 1 to m are located. By performing the sensing service reception PX symbol during the GP period, the sensing service reception PX does not cause any impact or interference on the communication uplink and downlink, and does not reduce the communication uplink and downlink rates and capacity. The sensing service reception beam direction is the m sensing service narrow beams contained in the (communication wide beam Com_Beam_i). By demodulating and detecting the sensing signal (OFDM-Chirp signal), the distance, direction, speed, etc. of the sensed target objects 1 to m are obtained, thereby realizing sensing functions such as detection, tracking, and imaging.

[0078] The present disclosure also provides a communication perception device, such as the device 600 shown in FIG6 , comprising: a perception coarse detection module 610, for coarsely detecting a target wide beam where a target object is located through a plurality of downlink communication symbols in a specific time slot of a communication signal; a hybrid multiplexing module 620, for multiplexing a perception transmission symbol on a downlink communication symbol before a guard interval symbol in a specific time slot to send a mixed data stream of a communication signal and a perception signal obtained based on hybrid precoding and hybrid beamforming, if a target wide beam exists; and a hybrid digital signal branching module 630, for using a perception reception symbol for perception reception during a guard interval symbol in a specific time slot to perceive a target narrow beam where a target object is located.

[0088] In some embodiments of the present disclosure, the mixed digital signal splitting module 730 may also be used to split the mixed signal of the communication signal and the perception signal sent from the mixed receiving channel module 760 into the communication signal and the perception signal.

[0089] In some embodiments of the present disclosure, the hybrid digital signal splitting module 730 may also be configured to output a communication signal during an uplink time slot and an uplink symbol, and send the communication signal to the communication signal flow module 740 .
