Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of wireless communication, in particular to a phase shift and time delay calculation method and system for a near-field communication and sensing integrated system. BACKGROUND

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

[0003] In addition, to meet the higher performance requirements of 6G for communication and sensing, super large-scale MIMO technology and high-frequency communication technology (such as millimeter wave) need to be introduced. On the one hand, super large-scale MIMO technology significantly improves system spectral efficiency and spatial resolution by deploying super large antenna arrays, and also leads to a fundamental change in channel modeling of electromagnetic wave propagation, i.e., from far-field channel modeling to near-field channel modeling; on the other hand, the increasing antenna array size and transmission bandwidth lead to beam squint effect, which significantly reduces the performance of traditional communication and sensing integrated systems. Specifically, the beam squint effect causes the analog beamforming direction to change with frequency, resulting in severe energy leakage. At the same time, the sensing process benefits from the beam squint channel containing more potential information, and through the beams focused on different positions generated at different frequencies, the sensing 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 system communication performance or using the beam squint effect for target estimation, and do not design for near-field communication and sensing integrated systems considering the beam squint effect to simultaneously perform communication and sensing processes.

[0058] 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, based on the echo signal, to provide three-dimensional spatial positioning services for the sensing target 3. A time delay-phase shift architecture three-dimensional beamformer is used for transmitting beamforming design to realize controllable beam squint in an orthogonal frequency division multiplexing system, so as to maximize the communication performance of the system under the performance requirements of the sensing service.

[0059] The dual-function base station 1 is configured with a time delay-phase shift architecture three-dimensional beamformer, and two layers of time delayers and one layer of phase shifters are cascaded to constitute the three-dimensional beamformer.

[0060] The two layers of time delayers are respectively equipped with and a time delay module, and the phase shifter layer is equipped with a phase shifter. Each time delay module in the first layer of time delayers is connected to one end of each time delay module in the second layer of time delayers, each time delay module in the second layer of time delayers is connected to one end of each phase shifter in the phase shifter layer at the other end, and the other end of each phase shifter in the phase shifter layer is connected to the base station antenna one by one.

Therefore, the beamforming vector generated by the time delay-phase shift architecture three-dimensional beamformer can be represented as:​​​ a time delay generated by the time delay module; representing the first corresponding to the baseband frequency of the subcarrier.

[0064] Step one: set a preset system sensing coverage range, the preset sensing coverage range is a three-dimensional space coverage range, including a preset system sensing angle domain coverage range and a preset system sensing distance domain coverage range, wherein the preset system sensing angle domain coverage range includes a preset system sensing horizontal angle domain coverage range and a preset system sensing vertical angle domain coverage range, and the preset system sensing coverage range and the preset system sensing resolution are used as performance indicators of the near-field integrated sensing system.

[0065] Specifically, the three-dimensional beamformer transmits a beamforming design to realize a controllable beam squint in an orthogonal frequency division multiplexing system, so as to maximize the communication performance of the system while meeting the performance requirements of the sensing service.

[0066] To realize the controllable beam squint effect to complete the communication and sensing processes at the same time, the preset system sensing space, i.e., the preset system sensing coverage range, includes angle domain and distance domain information, and is represented as:

[0083] The preset system perceived angle domain resolution is described as follows: when any direction within the system perceived space can be covered by one perceived beam, it is considered that the system perceived angle domain resolution can be met, and to quantify this standard, it is required that the azimuth angle and elevation angle intervals between beams of adjacent subcarriers are both less than the 3-dB beam width of all directions in the system perceived space Therefore, the preset system perceived angle domain resolution performance requirement is expressed as follows:

[0084] ;

[0085] In the formula, denotes the total number of subcarriers; denotes the subcarrier index; and denote the physical azimuth angles of the beams corresponding to the th subcarrier and the th subcarrier, respectively; and denote the physical elevation angles of the beams corresponding to the th subcarrier and the th subcarrier, respectively; denotes the 3-dB beam width, which is inversely proportional to the number of base station antennas.

[0086] The preset system perceived distance domain resolution is described as follows: similar to the preset system perceived angle domain resolution, the beam depth is introduced to represent the system perceived resolution in the distance domain, and it is required that any position in the system perceived space is covered by the 3-dB beam depth of at least one beam, and to quantify this standard, it is required that the interval of focusing distances between beams of adjacent subcarriers is less than the 3-dB beam depth of all focusing distances in the system perceived space In addition, the system perceived space should meet the requirement of near-field beamforming in the distance domain, that is, Therefore, the preset system perception distance resolution performance requirement is expressed as follows:

[0087]

[0088] wherein, and respectively represent the distance of the beam corresponding to the first subcarrier and the first subcarrier; represents the 3 decibel beam depth; represents the array aperture; represents the wavelength; represents the number of base station antennas.

[0089] Step five: to meet the preset system perception resolution performance requirement, through the analysis of the controllable beam squint effect and the preset system perception resolution, the final time delay range of each time delay device module of the system is represented as:

In addition, for the time delays of the time delay modules in the first layer time delay and the second layer time delay and

[0104] , a delay should be introduced to ensure that the time delays generated by all time delay modules in the first layer time delay and the second layer time delay are positive, thereby completing the actual time delay circuit implementation. Embodiment 2
