5G network stereo coverage scheme in subway scenario by Xi WANG, Zheng YANG, Peng ZHANG, Qin SHU, Xin PAN

“…As an urban artery and popular means of transportation, the subway is the most sustainable way of transportation.With the increase in operating mileage and passenger volume of subway and other rail transit, it faces greater challenges in operation, maintenance, security, scheduling, and other aspects.There is an urgent need for information technology to improve the level of subway operation services.While the foundation of subway informatization is effective indoor network coverage.At present, there are coverage requirements of multiple scenario such as outdoor wide area, indoor enclosed static scenes, and indoor enclosed high-speed sports scenes.For different coverage scenarios, if the same network method is chosen for coverage, there may be problems of high cost and poor coverage effect.Therefore, for the coverage of the subway network, it is necessary to flexibly combine macro station, micro station, room separation, leakage cable and other methods, combined with resource block (RB) guarantee, automatic handover, automatic login and other guarantee technologies, to meet the requirements of the network’s indicators such as insensitive switching, high data rate, low latency, high capacity, and large-scale connection under the optimal cost conditions, to ensure the normal operation of toB and toC business in subway scenarios.The 5G network stereo coverage scheme was studied in subway scenario, providing important reference for the coverage of other subway specialized networks.…”

Comprehensive Evaluation of Water Resources on a Long Time Scale Based on Analytic Hierarchy Process by CHEN Hao, ZHANG Yimin, ZHANG Xiaolin, XIONG Jia, DONG Qianjin

“…On a long time scale,the comprehensive water resources in the water resources system is not only related to natural incoming water,but also greatly affected by the underlying surface and human activities.Therefore,on a long time scale,the comprehensive water resources change is affected by many factors and closely related to social development.However,there is no consensus on the current research on assessing changes in comprehensive water resources by multiple factors on a long time scale.This paper constructs a comprehensive water resource evaluation system with 10 indicators in terms of natural incoming water,comprehensive water use,and social factors by the analytic hierarchy process,calculates the water resources volume by taking the upper reaches of Hanjiang River Basin as an example,and concludes that the comprehensive water resources of this river basin fluctuate greatly inter-year,but generally show a downward trend,as well as classifies the state of comprehensive water resources into 5 types according to different score intervals,and on this basis,analyzes the development trend of comprehensive water resources in the upper reaches of Hanjiang River Basin.The results show that the comprehensive water resources in the upper reaches of Hanjiang River Basin will be at high shortage risk in the future,so it is necessary to take reasonable measures to improve water efficiency.…”
