    Application of time-aware retransmission against reflection signal interferences in Internet of things by Han LUO, Yuhong LIU, Hongguang ZHANG, Chong ZHANG, Yuan’an LIU

    Published 2019-12-01
    “…In the enclosed spaces,wireless transmissions lead to the strong interferences of reflection signals,because of multipath effects.However,how to reduce the reflection signal effect on wireless transmissions is a kernel problem to expand the application scope of Internet of things.The time-aware retransmission MAC (TR-MAC) was proposed,which can adjust the time delay of each frame and reduce the interference caused by the reflected signal by using the reflection loss of the space conductor surface.In order to prove the adaptability of TR-MAC,an experimental environment that can generate strong reflection interference signals was used.The experimental results proved the feasibility and effectiveness of the TR-MAC in different environments.In a sense,TR-MAC extends the application of wireless communication in strongly reflective space.Besides,in the application of the Internet of things in the aircraft,ship and satellite,TR-MAC can realize wireless transmission instead of part of the wired transmission,so as to improve the system reliability,effective weight reduction and other important goals.…”

    Quantitative Analysis of Driving Factors of Grassland Degradation: A Case Study in Xilin River Basin, Inner Mongolia by Yichun Xie, Zongyao Sha

    Published 2012-01-01
    “…Based on the analysis of satellite vegetation maps from 1984, 1998, and 2004 for the Xilin River Basin, Inner Mongolia, China, and binary logistic regression (BLR) analysis, we observe the following: (1) grassland degradation is positively correlated with the growth density of climax communities; (2) our findings do not support a common notion that a decrease of biological productivity is a direct indicator of grassland degradation; (3) a causal relationship between grazing intensity and grassland degradation was not found; (4) degradation severity increased steadily towards roads but showed different trends near human settlements. …”

    Thoughts on the standardization evolution of 5G NTN network architecture by Jiancheng SUN, Jiaying SUN, Deshan MIAO, Chunlin LI

    Published 2023-08-01
    “…In recent years, 5G has been commercialized around the world in a large scale.However, considering the cost and geographical restrictions, traditional 5G networks still have trouble in providing seamless global communication.To reach the global area coverage, satellite and 5G technology integration has become a new hot topic in the communication industry.In 3GPP, the first release of 5G NTN technical specifications based on transparent payload architecture has been completed.Firstly, the standardization status of 5G NTN network architecture was introduced.Secondly, the shortcomings or issues existing in the current network architecture of 5G NTN were analyzed.Finally, three 5G NTN network architecture enhancement and optimization schemes were proposed, which including IAB-based network architecture, NTN adaptive network architecture and NTN multi-connection network architecture for intersatellite link construction and data shunt.The proposed architectures aim to providing valuable suggestions and references for the subsequent research, standardization and network deployment of 5G NTN.…”
