Description

Technical Field

[0001] The present invention relates to the field of wireless communication technology, and in particular to a phase shift and time delay calculation method and system for a near-field synaesthesia integrated system. Background Art

[0002] With the development of the sixth generation mobile networks (6G), communication and perception integration technology has received great attention, providing reliable low-latency links, higher communication transmission rates, and high-resolution and robust perception capabilities for emerging 6G applications. In the communication and perception integration system, communication signals can be used to provide positioning services for perceived targets, greatly reducing the related overhead of dedicated radar signals.

[0003] In addition, in order to meet the higher performance requirements of 6G for communication and perception, it is necessary to introduce ultra-large-scale MIMO technology and high-frequency band communication technology (such as millimeter wave, etc.). On the one hand, ultra-large-scale MIMO technology significantly improves the system spectrum efficiency and spatial resolution by deploying ultra-large antenna arrays, and also leads to a fundamental change in the channel modeling of electromagnetic wave propagation, that is, from far-field channel modeling to near-field channel modeling; on the other hand, the growing antenna array size and transmission bandwidth lead to the beam squint effect, which significantly reduces the performance of the traditional communication perception integrated system. Specifically, the beam squint effect causes the simulated beamforming direction to change with the frequency, resulting in serious energy leakage. But at the same time, the perception process benefits from the beam squint channel containing more potential information. By generating beams focused at different positions at different frequencies, the perception process has the potential to collect more comprehensive information from the channel environment. However, existing technologies often only focus on eliminating the beam squint effect to improve the system communication performance or using the beam squint effect for target estimation, and have not been designed for the near-field communication perception integrated system considering the beam squint effect to perform communication and perception processes simultaneously.

For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " generally indicates that the related objects are in an "or" relationship.

[0019] Example 1 like Figure 1 As shown, this embodiment introduces a phase shift and time delay calculation method for a near-field synaesthesia integrated system, which specifically includes the following steps: like Figure 2 The figure shows a schematic diagram of the structure of the near-field synaesthesia integrated system of this embodiment, including a dual-function base station 1, a communication user 2, and a sensing target 3; The dual-function base station 1 is used to transmit signals carrying communication information to provide downlink communication services for the communication user 2, and at the same time provide three-dimensional spatial positioning services for the perception target 3 based on the echo signal. A three-dimensional beamformer with a delay-phase shift architecture is used for transmit beamforming design to achieve controllable beam squint in an orthogonal frequency division multiplexing system, thereby maximizing the communication performance of the system while meeting the performance requirements of the perception service.

[0020] The dual-function base station 1 is configured with a three-dimensional beamformer of a time delay-phase shift architecture, and two layers of time delay devices and one layer of phase shifter are cascaded to form the three-dimensional beamformer; The two layers of delay devices are equipped with and Delay module, phase shifter layer equipped with A phase shifter, each delay module in the first layer of delay layer is connected to one end of each delay module in the second layer of delay layer, the other end of each delay module in the second layer of delay layer is connected to one end of each phase shifter in the phase shifter layer, and the other end of each phase shifter in the phase shifter layer is connected one-to-one with the base station antenna.

[0021] Therefore, the beamforming vector generated by the three-dimensional beamformer of the delay-phase shift architecture can be expressed as: ; in, , Indicates The phase shift produced by the phase shifter; and They represent the first delay layer The delay module and the second delay layer The delay caused by the delay module; Indicates The baseband frequency corresponding to the subcarrier.

[0022] Step 1: Set a preset system perception coverage range, where the preset perception coverage range is a three-dimensional space coverage range, including a preset system perception angle domain coverage range and a preset system perception distance domain coverage range, wherein the preset system perception angle domain coverage range includes a preset system perception horizontal angle domain coverage range and a preset system perception vertical angle domain coverage range, and the preset system perception coverage range and the preset system perception resolution are used as performance indicators of the near-field synaesthesia integrated system perception service.

[0023] Specifically, a three-dimensional beamformer transmit beamforming is designed to achieve steerable beam squint in an orthogonal frequency division multiplexing system, thereby maximizing the communication performance of the system while meeting the performance requirements of the sensing service.

[0024] In order to realize the controllable beam squint effect to complete the communication and perception process at the same time, the preset system perception space, that is, the preset system perception coverage range, includes angle domain and distance domain information, which is expressed as: ; In the formula, Indicates the distance within the preset system perception coverage range; Indicates the physical azimuth within the preset system perception coverage; Indicates the physical pitch angle within the preset system perception coverage; and They respectively represent the minimum distance and maximum distance within the preset system perception coverage range; and They respectively represent the minimum physical azimuth and the maximum physical azimuth within the preset system perception coverage; and They respectively represent the minimum physical pitch angle and the maximum physical pitch angle within the preset system perception coverage range.

[0025] Step 2: To meet the performance requirements of the preset system perception coverage, through the analysis of the squint effect of the steerable beam, the configuration of the phase shifter in the 3D beamformer should make the beam on the 0th subcarrier of the orthogonal frequency division multiplexing system align with the minimum angle and minimum distance of the perception space, that is, , thus the phase shift of each phase shifter in the system can be obtained according to the near-field uniform spherical wave channel, which is expressed as: ; in, ; ; In the formula, Indicates The phase shift of a phase shifter; Indicates the lowest frequency of the system; represents the speed of light; and Respectively represent The row and column indices of the phase shifters, , ; Indicates the antenna spacing; and They respectively represent the minimum spatial azimuth and minimum spatial elevation angle within the preset system perception coverage range.

[0026] Step 3: To meet the performance requirements of the preset system perception coverage, through the analysis of the squint effect of the controllable beam, the initial delay of the delay module in the first delay layer and the second delay layer should be such that the first The beam on the subcarrier is aligned with the maximum angle and maximum distance of the sensing space, that is, , so the initial delay range of each delay module in the system is expressed as: ; in, Indicates the first layer The initial delay range of each delay module; Indicates the second layer The initial delay range of each delay module; and Respectively represent the first layer The delay module and the second layer The minimum delay that can be achieved by a delay module.

[0027] By analyzing the near-field uniform spherical wave channel, we can obtain and As shown below: ; ; In the formula, Indicates the highest frequency of the system; Indicates the maximum spatial azimuth within the preset system perception coverage range; Indicates the system bandwidth; Indicates the maximum spatial pitch angle within the preset system perception coverage range.

[0028] Step 4: Set a preset system perception resolution, wherein the preset system perception resolution includes a preset system perception angle domain resolution and a preset system perception distance domain resolution, wherein the preset system perception angle domain resolution includes a preset system perception horizontal angle domain resolution and a preset system perception vertical angle domain resolution, and use the achievable rate as the performance indicator of the system communication service.

[0029] The preset system perception angle domain resolution is described as follows: If any direction within the system can be covered by a sensing beam, it is considered that the system perception angle domain resolution can be met. To quantify this standard, it is required that the azimuth and elevation angle intervals between the beams of adjacent subcarriers are smaller than the system perception space. The 3 dB beamwidth in all directions is used, so the preset system perception angle domain resolution performance requirement is expressed as follows: ; In the formula, Indicates the total number of subcarriers; Indicates the subcarrier index; and Respectively represent Subcarrier and The physical azimuth of the beam corresponding to the subcarrier; and Respectively represent Subcarrier and The physical elevation angle of the beam corresponding to the subcarrier; Represents a 3 dB beam width, which is inversely proportional to the number of base station antennas.

[0030] The preset system perception distance domain resolution is described as follows: Similar to the preset system perception angle domain resolution, the beam depth is introduced to characterize the system perception resolution in the distance domain, requiring the system to perceive the space Any position in the system is covered by at least one beam depth of 3 dB. To quantify this standard, the interval between the focusing distances of the beams of adjacent subcarriers is required to be less than the system perception space. 3 dB beam depth at all focus distances, in addition, the system senses the space In the distance domain, the requirements of near-field beamforming should be met, that is, , so the preset system perception distance resolution performance requirements are expressed as follows: ; In the formula, and Respectively represent Subcarrier and The distance of the beam corresponding to the subcarrier; Indicates 3 dB beam depth; represents the array aperture; Indicates wavelength; Indicates the number of base station antennas.

[0031] Step 5: In order to meet the performance requirements of the preset system perception resolution, through the analysis of the controllable beam squint effect and the preset system perception resolution, the final delay range of each delay module of the system is expressed as: ; in, Indicates the first layer The final delay range of each delay module; Indicates the second layer The final delay range of each delay module; and Respectively represent the first layer The delay module and the second layer The maximum delay that can be achieved by a delay module.

[0032] By analyzing the near-field uniform spherical wave channel, we can obtain and As shown below: ; ; in, ; ; In the formula, Indicates the maximum spatial orientation angle under the preset system perception resolution; Indicates the maximum distance under the preset system perception resolution; Indicates the maximum spatial pitch angle under the preset system perception resolution; and They respectively represent the maximum physical azimuth and the maximum physical pitch angle under the preset system perception resolution, and are obtained by analyzing the performance requirements of the preset system perception angle resolution and the preset system perception distance resolution.

[0033] Step 6: By analyzing the impact of phase shift and delay on communication and perception performance, obtain the delay of each delay module under the maximum achievable rate of the communication user within the final delay range. Specifically, when and When , the delay that maximizes the communication performance of the system while meeting the performance requirements of the perception service is expressed as: ; ; In the formula, Indicates the maximum achievable rate of communication users in the first layer The delay of each delay module; Indicates the second layer under the maximum achievable rate of communication users The delay of a delay module.

[0034] when or When the preset system perception coverage range conflicts with the preset system perception resolution requirement, the system is considered unfeasible and it is necessary to reduce the system perception coverage range or lower the system perception resolution requirement to make the system feasible.

[0035] In addition, the delay between the delay module in the first layer of delay and the delay module in the second layer of delay and , a delay should be introduced This ensures that the delays generated by all the delay modules in the first delay layer and the second delay layer are positive numbers, thereby completing the actual delay circuit implementation.

[0037] In this embodiment, the number of base station antennas in the communication and sensing integration system is set to The system carrier frequency is 60GHz, the millimeter wave orthogonal frequency division multiplexing system bandwidth is 1GHz, the number of subcarriers is 128, the base station antenna spacing is half the carrier wavelength, and the perception space , using 3 dB beam width and 3 dB beam depth.

[0038] Figure 3 The two curves in are the changes of the system communication rate with the transmission signal-to-noise ratio obtained by this embodiment and the traditional calculation method, respectively, where the traditional calculation method is based on time domain beam scanning. It can be seen that the scheme proposed in this embodiment achieves a significant improvement in the communication rate, verifies the proposed phase shift and delay calculation method for the near-field synaesthesia integrated system, realizes the communication and perception process simultaneously based on the near-field beam squint, maximizes the achievable rate of the communication user while ensuring sufficient perception range and perception resolution, and has significant advancement and effectiveness.
