To facilitate understanding, some contents involved in the embodiments of this application are described below:

1. Synaesthesia integration.

In the future, Beyond 5 Generation (B5G) and 6G wireless communication systems are expected to provide various high-precision sensing services, such as indoor positioning for robot navigation, Wi-Fi sensing for smart homes, and radar sensing for autonomous vehicles. . Sensing and communication systems are often designed separately and occupy different frequency bands. Then, due to the widespread deployment of millimeter wave and massive multiple-input multiple-output (MIMO) technologies, communication signals in future wireless communication systems tend to have high resolution in both the time domain and the angle domain, which makes It becomes possible to use communication signals to achieve high-precision sensing. Therefore, it is best to jointly design sensing and communication systems so that they share the same frequency band and hardware to improve frequency efficiency and reduce hardware costs. This has prompted research on Integrated Sensing And Communication (ISAC). ISAC will become a key technology in future wireless communication systems to support many important application scenarios. For example, in future autonomous vehicle networks, autonomous vehicles will obtain a large amount of information from the network, including ultra-high-resolution maps and near-real-time information, to navigate and avoid upcoming traffic jams. In the same context, radar sensors in autonomous vehicles should be able to provide powerful, high-resolution obstacle detection with resolutions on the order of centimeters. ISAC technology for autonomous vehicles offers the possibility to achieve high data rate communications and high-resolution obstacle detection using the same hardware and spectrum resources. Other applications of ISAC include Wi-Fi-based indoor positioning and activity recognition, drone communication and sensing, extended reality (Extended Reality, XR), radar and communication integration, etc.

JSAC achieves integrated low-cost implementation of dual functions of communication and perception through hardware device sharing and software-defined functions. Its main features are: first, unified and simplified architecture; second, reconfigurable and scalable functions; third, efficiency improvement and cost reduction. reduce. The advantages of communication perception integration mainly include three aspects: first, reduced equipment cost and size; second, frequency Spectrum utilization is improved, and thirdly, system performance is improved.

The development of ISAC is divided into four stages: coexistence, co-operation, co-design and co-collaboration.

Coexistence: Communication and perception are two separate systems. The two will interfere with each other. The main methods to solve the interference are: distance isolation, frequency band isolation, time-division work, Multiple Input Multiple Output (MIMO) technology and prediction Coding etc.

Co-operation: Communication and perception share a hardware platform and use shared information to improve common performance. The power allocation between the two has a greater impact on system performance.

Co-design: Communication and perception become a complete joint system, including joint signal design, waveform design, coding design, etc. In the early stage, there were linear frequency modulation waveforms, spread spectrum waveforms, etc., and later focused on Orthogonal Frequency Division Multiplexing technology (Orthogonal Frequency Division) Multiplexing, OFDM) waveforms, MIMO technology, etc.

Collaboration: Multiple communication-aware integrated nodes collaborate with each other to achieve public goals. For example, radar detection information is shared through communication data transmission. Typical scenarios include driving assistance systems, radar-assisted communications, etc.

2. Radar technology.

With the development of radar technology, radar detection of targets not only measures the distance of the target, but also measures the speed, azimuth angle, and pitch angle of the target, and extracts more information about the target from the above information, including the size and shape of the target. wait.

Radar technology was originally used for military purposes to detect aircraft, missiles, vehicles, ships and other targets. With the development of technology and the evolution of society, radar is increasingly used in civilian scenarios. A typical application is that weather radar measures the echoes of meteorological targets such as clouds and rain to determine the location, intensity and other information about clouds and rain for weather forecasting. Furthermore, with the vigorous development of the electronic information industry, Internet of Things, communication technology, etc., radar technology has begun to enter people's daily life applications, greatly improving the convenience and safety of work and life. For example, automotive radar provides early warning information for vehicle driving by measuring the distance and relative speed between vehicles, between vehicles and surrounding objects, and between vehicles and pedestrians, which greatly improves the safety level of road traffic.

On a technical level, radar is classified in many ways. According to the positional relationship between radar transceiver sites, it can be divided into: single-station radar and dual-station radar. For single-station radar, the signal transmitter and receiver are integrated and share an antenna; the advantage is that the target echo signal and the local oscillator of the receiver are naturally coherent, and signal processing is more convenient; the disadvantage is that signal transmission and reception cannot be performed at the same time, and can only be Signal waveforms with a certain duty cycle lead to blind spots in detection, which require complex algorithms to compensate; or signals can be sent and received at the same time, with strict isolation between sending and receiving, but this is difficult to achieve for high-power military radars. For dual-station radar, the signal transmitter and receiver are located at different locations; the advantage is that signal transmission and reception can be carried out simultaneously, and continuous wave waveforms can be used for detection; the disadvantage is that it is difficult to achieve the same frequency and coherence between the receiver and transmitter, and the signal The processing is more complicated.

In synaesthesia integrated wireless sensing applications, radar technology can adopt single-station radar mode or dual-station radar mode.

In the single-station radar mode, the transmitting and receiving signals share the same antenna, and the receiving signals and the transmitting signals enter different radio frequency processing links through the circulator; in this mode, the continuous wave signal waveform can be used to achieve detection without blind zones, provided that the receiving signal The signal needs to be well isolated from the transmit signal, usually around 100dB, to eliminate the leakage of the transmit signal from flooding the received signal. Since the single-station radar receiver has all the information of the transmitted signal, it can perform signal processing through matched filtering (pulse compression) to obtain higher signal processing gain.

In the dual-station radar mode, there is no isolation problem of sending and receiving signals, which greatly simplifies the complexity of the hardware. Since radar signal processing is based on known information, in 5G NR synaesthetic integration applications, known information such as synchronization signals and reference signals can be used for radar signal processing. However, due to the periodicity of synchronization signals, reference signals, etc., the blur diagram of the signal waveform is no longer a pushpin shape, but a nail plate shape. The degree of delay and Doppler ambiguity will increase, and the gain of the main lobe will be relatively small. The single-station radar mode is much slower, reducing the range of distance and speed measurements. Through appropriate parameter set design, the measurement range of distance and speed can meet the measurement needs of common targets such as cars and pedestrians. In addition, the measurement accuracy of dual-station radar is related to the position of the transceiver site relative to the target, and it is necessary to select an appropriate transceiver site pair to improve detection performance.

The perception processing method provided by the embodiments of the present application will be described in detail below with reference to the accompanying drawings through some embodiments and their application scenarios.

The goal of this embodiment is to perceive the sensing object in Figure 3. In this embodiment, the base station may be an access base station for the terminal, or may not be an access base station for the terminal. The above-mentioned first device is a sensing function network element, the first sensing node is a terminal, the second sensing node is a base station, and the reference target is a RIS device.

In order to compensate for the timing deviation between the terminal and the base station, or the frequency offset, or the phase deviation between the antenna ports of the base station, the first signal delay caused by the sensing object, or Doppler, or The angle of the sensing object relative to the base station is sensed through the sensing reference signal (first signal) to the reference target (RIS device) in a known state: it can be sensed through the positional relationship between the terminal, the base station and the reference target (RIS device) The real delay of the reference signal from the terminal to the reference target and then to the base station, as well as the angle of the reference target (RIS equipment) relative to the base station, while the reference target (RIS equipment) is in a stationary state and its Doppler is zero; thus, we obtain Second perception result.
