[0225] Wireless communication and wireless sensing share a high degree of similarity. Integrated Sensing and Communication (ISAC) can unite wireless communication and wireless sensing, fostering close collaboration between the two. This approach benefits both wireless communication and wireless sensing, improving both the effectiveness and reliability of wireless communication and the accuracy of wireless sensing. Furthermore, devices that support both wireless communication and wireless sensing can reduce network deployment costs.

[0226] Wireless sensing typically requires estimating the target's range, azimuth angle (such as horizontal and vertical angles), and velocity. Broadly speaking, sensing also includes wireless tracking and radio frequency identification of the target. To achieve high-precision sensing, a sensing transmitter typically transmits a dedicated reference signal for sensing, which, for ease of description, will be referred to as a sensing reference signal. Optionally, the sensing reference signal does not carry any information or data used for communication.

[0227] FIG1 is a schematic diagram of a perception system according to an embodiment of the present disclosure. As shown in FIG1 , the perception system 100 may include a perception transmitter 101 and a perception receiver 102 .

[0228] In some embodiments, in a monostatic mode, the sensing transmitter 101 may transmit a sensing reference signal and estimate at least one of the distance, angle, and speed of the sensing target by measuring an echo of the sensing reference signal.

[0229] In some embodiments, in a bistatic mode, the sensing transmitter 101 may transmit a sensing reference signal, and the sensing receiver 102 may receive and measure the sensing reference signal to estimate at least one of the distance, angle, and speed of the sensing target.

[0230] It should be noted that the number of cognitive transmitters and the number of cognitive receivers shown in Figure 1 are only examples and do not constitute a limitation on the embodiments of the present disclosure. In actual situations, there can be one or more cognitive transmitters and one or more cognitive receivers.

[0231] It can be understood that the perception system in the embodiment of the present disclosure can correspond to a variety of perception scenarios, for example, it can be used for perception between terminals, or for perception between terminals and network devices, or for perception between network devices and network devices, etc.

[0232] In some embodiments, the sensing transmitter may be located in a terminal or a network device.

[0233] In some embodiments, the perceptual receiver may be located in a terminal or a network device.

[0234] In one example, the perceptual transmitter and the perceptual receiver may be located in a network device.

[0235] In one example, the perceptual transmitter may be located in a network device, and the perceptual receiver may be located in a terminal.

[0236] In one example, the perceptual transmitter may be located in a terminal, and the perceptual receiver may be located in a network device.

[0237] In one example, the perceptual transmitter and the perceptual receiver may be located in a terminal.

[0238] In some embodiments, the terminal may include at least one of a mobile phone, a wearable device, an Internet of Things device, a car with communication capabilities, a smart car, a tablet computer, a computer with wireless transceiver capabilities, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal device in industrial control, a wireless terminal device in self-driving, a wireless terminal device in remote medical surgery, a wireless terminal device in a smart grid, a wireless terminal device in transportation safety, a wireless terminal device in a smart city, and a wireless terminal device in a smart home, but is not limited thereto.

[0239] In some embodiments, the network device is, for example, an access network device, which may include an evolved NodeB (eNB), a next generation evolved NodeB (ng-eNB), a next generation NodeB (gNB), a node B (NB), a home node B (HNB), a home evolved nodeB (HeNB), a wireless backhaul device, a radio network controller (RNC), a base station controller (BSC), a base transceiver station (BTS), a base band unit (BBU), a mobile switching center, a base station in a 6G communication system, an open base station (Open RAN), a cloud base station (Cloud RAN), a base station in other communication systems, and at least one of an access node in a Wi-Fi system, but is not limited thereto.

[0240] Based on the sensing system shown in Figure 1, taking the distance estimation of a sensing target as an example, the sensing receiver needs to accurately estimate the arrival time of the first echo path reflected by the sensing target (in single-station mode) or the first path scattered by the sensing target (in dual-station mode). It should be understood that wireless sensing is sensitive to interference. To ensure wireless sensing accuracy, the sensing receiver should minimize interference when measuring the sensing reference signal.

[0241] In high-frequency bands such as millimeter wave (mmWave), sub-terahertz (subThz), and terahertz (THz), propagation losses are extremely severe. In such cases, beamforming is essential for sensing. Otherwise, severe high-frequency transmission losses will significantly reduce sensing accuracy and performance.

[0242] When beamforming is used, high-precision perception is limited to targets within or near the beam's coverage area. For targets outside the beam's coverage area or far from the beam's area, perception accuracy is lower, and perception performance cannot be guaranteed. Therefore, the sensing transmitter must perform beam sweeping to achieve perception of surrounding targets. To quickly achieve this, the sensing transmitter can simultaneously transmit multiple beams pointing in different directions to perform beam sweeping in parallel.

[0243] The cognitive transmitter needs to send a cognitive reference signal based on a pattern of the cognitive reference signal. The pattern of the cognitive reference signal can be determined based on a time domain pattern and a frequency domain pattern. In some embodiments, the frequency domain pattern of the cognitive reference signal can be determined by one of the following implementations, but is not limited thereto.

[0244] (1) Perception reference signals based on coprime integers

[0245] In some embodiments, the frequency domain pattern of the perceptual reference signal can be expressed as one of the following sets: S = {q·P·K min +N subc PRB ·K0+k0|q=0,1,…,Q-1}∪{p·Q·K min +N subc PRB ·K0+k0|p=0,1,…,2P-1}; S={q·P·K min +N subc PRB ·K0+k0|q=0,1,…,Q-1}∪{p·Q·K min +N subc PRB·K0+k0|p=1,…,2P-1}; S={q·P·K min +N subc PRB ·K0+k0|q=1,…,Q-1}∪{p·Q·K min +N subc PRB K0+k0|p=0,1,…,2P-1};

[0246] in:

[0247] S represents the set of subcarrier positions occupied by the frequency domain pattern of the perception reference signal;

[0248] P and Q are a pair of mutually prime integers, and P is less than Q;

[0252] k0 represents the number of the starting subcarrier of the perception reference signal within the PRB where it is located.

[0253] In the above implementation, the perceptual reference signal can achieve a higher uniform degree of freedom (uDoF) and a higher resolution in the Khatri-Rao subspace.

[0254] (2) Nested Perceptual Reference Signals

[0255] In some embodiments, the frequency domain pattern of the perceptual reference signal may be represented as one of the following sets:

[0256] in:

[0257] S represents the set of subcarrier positions occupied by the frequency domain pattern of the perception reference signal;

[0258] N represents the number of subcarriers occupied by the frequency domain pattern of the perception reference signal;

[0259] K min Indicates the minimum frequency domain spacing between subcarriers where frequency domain adjacent perception reference signals are located;

[0262] k0 represents the number of the starting subcarrier of the perception reference signal within the PRB where it is located.

[0264] In the above implementation, the perceptual reference signal can achieve a higher uniform degree of freedom (uDoF) and a higher resolution in the Khatri-Rao subspace.

[0265] (3) Uniform perceptual reference signal

[0273] k0 represents the number of the starting subcarrier of the perception reference signal within the PRB where it is located.

[0274] It is understandable that the several perception reference signal patterns proposed above are only applicable to single-port scenarios and do not support multiple ports or multi-beam scanning. In this case, the perception transmitter can only perform single-beam scanning, resulting in a longer time to complete perception of surrounding targets. Therefore, the embodiments of the present disclosure further consider expanding the perception reference signal from a single port to multiple ports to support multi-beam scanning.
