Leveraging current 5G technology, upgrades can be made to 5G’s transmission-reception mode, spatial multiplexing method, sensing waveform, and resource allocation. By deploying parameters like the communication-sensing task switch in the 5G system, can be upgraded to a 5G-Advanced (5G-A) system. This upgrade addresses 5G coverage gaps in low-altitude areas, enhances the connectivity of low-altitude terminals, mitigates low-altitude waveform interference, and ultimately achieves precise interconnection management of low-altitude unmanned aerial vehicles and improve low-altitude sensing capabilities.
As a representative of new-quality productive forces, the low-altitude economy has achieved rapidly development relying on new-form applications such as civil unmanned aerial vehicles and low-altitude manned aircraft, and has gradually become a new engine driving China’s economic growth. With the continuous advancement of 5G-A technology, to meet the demand of low-altitude mobile users for continuous, high-quality, and deep coverage, building an air-ground integrated three-dimensional network based on International Mobile Telecommunications (IMT) networks boasts advantages such as reuse of site resources and frequency resources, as well as high efficiency in integrated network construction and operation. However, traditional IMT networks mainly focuses on terrestrial users, with limited research on high-quality continuous coverage networking in low-altitude scenarios and mobility management for air-ground users. To address issues such as complex airspace coverage gaps and declining network quality for ground users, this paper explores the integration of reconfigurable intelligent surface (RIS) technology into low-altitude mobile communication networks, and proposes a low-altitude networking architecture assisted by RIS at the transceiver side and channel side. Then this paper provides a cost-effective, low-power, and easily deployable solution for high-quality, continuous, and deep coverage in low-altitude areas.

Digital trade plays an important role in the reorganization of global factor resources and shaping of international competitive advantages. The statistical measurement of the digital trade scale plays a fundamental and pioneering role in judging the development trend of digital trade and analyzing the macro-analysis of digital trade. However, no authoritative and unified statistical measurement scheme has been formed globally, which cannot meet the needs of national digital trade development. Therefore, firstly, this paper summarizes the domestic and international research dynamics and statistical practice. Then, it combines the practical work experience and data summarization to accurately identify the key and difficult points of statistical measurement, such as the statistics of the digital actual delivery service trade and the multiple data sources. Finally, it discusses the path and feasible suggestions for the realization of the statistical measurement of China’s digital trade scale from the short-, medium- and long-term perspectives on the basis of the statistical principles.

In V2X direct communication, vehicles continuously send their own position coordinate during driving, and roadside communication equipment continuously broadcast the road map coordinate information, but there is a lack of coordinate information protection measures in V2X direct communication protocols, so the vehicle’s travelling trajectory and the regional map information can be easily accessed by external parties, which poses a potential security risk to the national geographic information security. Two format-preserving encryption algorithms based on the Feistel structure and the hash algorithm were proposed to realize the encryption of coordinate information. Experimental results show that the two encryption algorithms proposed can meet the coordinate encoding requirement of V2X protocol. The encryption and decryption performance meet the requirements of practical applications, and the delay is negligible.
