Embodiment Construction

[0086] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0087] In order to ensure the reliability and accuracy of environmental perception information acquired by intelligent machines under various environmental conditions (such as weather conditions, air pollutants, etc.), the millimeter wave sensing function is essential. In the future intelligent machine network Among them, the millimeter wave sensing function is expected to be deployed on both the base station side and the machine terminal side. At the same time, the millimeter-wave communication function on the base station side is an important capability to meet the requirements for large-bandwidth and low-latency transmission. In the traditional discrete millimeter-wave sensing and communication design, discrete millimeter-wave communication requi...

Abstract

The invention provides a communication perception integration method, device, base station and system, and the method comprises the steps: receiving a first communication signal which comprises an uplink transmission signal transmitted by a terminal, and / or an echo signal formed after a downlink transmission signal transmitted by the base station is reflected by a scattering target, the scattering target comprises a terminal and a non-communication target; and on the basis of a super-resolution sensing algorithm, signal processing is performed on the first communication signal so as to detect and obtain a communication sensing result, and the communication sensing result comprises at least one of the following items: the direction of arrival, the distance and the speed. The problem that in the prior art, the distance measurement and speed measurement precision in communication and perception integration is too low is solved.

Description

technical field [0001] The invention relates to the wireless air interface technology of a mobile communication system, in particular to a method, device, base station and system for communication perception integration. Background technique [0002] With the rapid development of wireless communication technology in the past 30 years, the frequency spectrum allocated to wireless communication is constantly developing towards high frequency band and large bandwidth. Especially after the opening of the millimeter wave frequency band, the frequency spectrum for wireless communication and the frequency spectrum allocated for radar sensing show an increasingly obvious trend of integration. In addition, with the rapid development of digital signal processing technology, the structures and functions of the digital signal processing modules of radar perception and wireless communication systems are becoming more and more similar. These provide great possibilities for wireless perce...
