The solution provided in the present disclosure is about a communication perception integration method, device and system based on hybrid precoding and hybrid beamforming. Through the design of perception signals and the design of the synaesthesia integration system, the perception beam is mixed into the communication beam to realize hybrid multi-user multiple input multiple output (Multi-User Multiple-Input Multiple-Output, MU-MIMO). For ease of understanding, several terms involved in this application are first explained below.

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.

Mixed Beam Forming (MBF): The communication signal to be sent is mixed with the perception signal to obtain a mixed signal, and then the mixed signal is subjected to mixed 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 the communication signal and the perception signal respectively.

Radar signals: including swept cosine (Chirp) signals, orthogonal frequency division multiplexing-swept cosine signals (OFDM-Chirp) and continuous wave signals (Continue Wave), etc.

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 modulation signal of the OFDM symbol. A swept cosine signal is a signal with linear frequency variation, and its frequency increases or decreases linearly over time. In OFDM-Chirp, a swept cosine signal is superimposed on the subcarrier of each OFDM symbol, thus achieving frequency variation in the frequency domain.

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 techniques. 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 are not directly connected to each other. Will not interfere with each other.

Multi-User Multiple-Input Multiple-Output (MU-MIMO) is a space division multiplexing technology. In MU-MIMO, the base station sends independent data streams to multiple user terminals at the same time, using multiple antennas for transmission, thus achieving parallel data transmission between multiple users.

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.

In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present disclosure, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

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.

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

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

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

Among them, the detected target objects can be vehicles, drones, airplanes, ships, etc.

For example, FIG2 shows a communication signal schematic diagram of a 2.5 ms period with one S time slot in each period, where the communication signal stream 210 of the S time slot includes a frame structure of 10DL(D):2GP:2UL(U). In FIG2, the first 8 downlink communication symbols of the communication signal stream (i.e., the data stream of the communication signal) 210 are used for communication services and perception services coarse detection 220 to preliminarily perceive the target wide beam where the target object is located.

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

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.

Among them, the communication signal is an Orthogonal Frequency Division Multiplexing (OFDM) signal.

Among them, the sensing signal is a radar signal.

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

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.

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

The method of the disclosed embodiment realizes coarse detection of perception services through downlink communication symbols in specific time slots of communication signals, preliminarily perceives that the perceived object (e.g., target object) is on a certain communication signal stream (wide) beam, improves perception efficiency, and provides a method and process that meets the needs of perception services under different accuracies.

Furthermore, the method of the embodiment of the present disclosure implements hybrid preprocessing and hybrid beamforming of perception beams and communication beams, realizes consistent processing of hybrid beams, and saves processing, maintenance and optimization costs.

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.

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.

In some embodiments of the present disclosure, step S110 may also be, for example, a coarse detection scenario 300 as shown in FIG3. The first multiple downlink communication symbols (D) in a specific time slot (e.g., S time slot) of the communication signal use OFDM waveforms to perform communication services while performing coarse detection of sensing services, and preliminarily sense that the sensed object is on a wide beam of a data stream of a certain (or several) communication signal.

In some embodiments of the present disclosure, the wide beams of the data streams of multiple communication signals can be coarsely detected at the same time or coarsely detected in polling time. As shown in Figure 3, on the communication wide beam i, the communication wide beam index is Com_Beam_i, and other communication wide beams Com_Beam_1~Com_Beam_n (except 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 used for perception detection of target objects 1~target objects m towards the sky, and the others are used for communication with ordinary terminals UE1~UEn towards the ground). However, in special cases, that is, when the perception service beam overlaps with the communication service beam direction, they can be staggered in time, and the beam used for perception coarse detection is prioritized or the beam used for communication services is prioritized. As a coarse detection of perception services with low precision requirements, it can also be used as the basis for fine detection of perception services with high precision requirements, improve detection efficiency, and meet the needs of perception services under different precisions.

As shown in FIG3 , when target objects 1 to m encounter beam Com_Beam_i, a reflected echo will be generated, thereby causing co-frequency interference between the reflected echo and the transmitted signal. Therefore, in some embodiments of the present disclosure, the method of the embodiment of the present disclosure may also include: during coarse detection, using a communication signal to cancel the reflected echo from the target object. For example, the transmitted communication signal is adjusted to have a co-frequency interference delay, equal amplitude, and opposite phase with 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-frequency reception and improves the coarse detection performance.

In some embodiments of the present disclosure, step S120 may further include: the data stream of the communication signal adopts orthogonal The data streams of the frequency division multiplexing signal and the sensing signal are mixed with the radar signal to generate MU-MIMO.

In the scenario 400 shown in FIG. 4 , on the downlink communication symbol D before the guard interval symbol GP in a specific time slot, the perception transmission symbol PT is multiplexed to send a mixed data stream of a communication signal data stream (OFDM) and a perception signal data stream (radar signal) obtained based on hybrid precoding and hybrid beamforming. Among them, OFDM signals and radar signals realize hybrid MU-MIMO (spatial division multiplexing) under hybrid precoding and hybrid digital beamforming processing; that is, (n-1) communication wide beams (communication wide beams Com_Beam_1~Com_Beam_n, except i, n is a positive integer greater than or equal to 1, i is a positive integer greater than or equal to 1 and less than n) and m perception service narrow beams (perception service narrow beams PT_Beam_1~PT_Beam_m correspond to target object 1~target object m respectively) contained in one communication wide beam (communication wide beam Com_Beam_i) are hybrid MU-MIMO, a total of (n-1) wide beams + m narrow beams, that is, n-1+m hybrid beams. m is a positive integer greater than or equal to 1.

In the method of the embodiment of the present disclosure, in MU-MIMO, the base station simultaneously sends independent data streams to multiple user terminals, using multiple antennas for transmission, thereby achieving parallel data transmission between multiple users. In this way, multiple users can simultaneously communicate data on the same spectrum resource, thereby improving spectrum utilization.

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, thereby eliminating interference between users and improving the capacity and performance of the communication system.

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, it has high spectrum efficiency in the frequency domain and can transmit multiple data streams 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. Further, the characteristics of the swept cosine signal Chirp are combined with the high spectrum efficiency of OFDM to achieve high-efficiency transmission in the frequency domain and time domain.

In some embodiments of the present disclosure, step S130 may also be, for example, the scenario 500 shown in FIG5 , in which the sensing reception symbol PX is used to perform sensing reception during the guard interval symbol GP in a specific time slot 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 to the communication uplink and downlink links, and does not reduce the communication uplink and downlink rates and capacities. The sensing service reception beam direction is the m sensing service narrow beams contained in the (communication wide beam Com_Beam_i), and the distance, orientation, speed, etc. of the sensed target objects 1 to m are obtained by demodulating and detecting the sensing signal (OFDM-Chirp signal), thereby realizing sensing functions such as detection, tracking, and imaging.
