| 1 | Vision,Requirements and Network Architecture of 6G Mobile Network beyond 2030显示文摘With the 5th Generation(5G)Mobile network being rolled out gradually in 2019,the research for the next generation mobile network has been started and targeted for 2030.To pave the way for the development of the 6th Generation(6G)mobile network,the vision and requirements should be identified first for the potential key technology identification and comprehensive system design.This article first identifies the vision of the society development towards 2030 and the new application scenarios for mobile communication,and then the key performance requirements are derived from the service and application perspective.Taken into account the convergence of information technology,communication technology and big data technology,a logical mobile network architecture is proposed to resolve the lessons from 5G network design.To compromise among the cost,capability and flexibility of the network,the features of the 6G mobile network are proposed based on the latest progress and applications of the relevant fields,namely,on-demand fulfillment,lite network,soft network,native AI and native security.Ultimately,the intent of this article is to serve as a basis for stimulating more promising research on 6G. | Guangyi Liu Yuhong Huang Na Li Jing Dong Jing Jin Qixing Wang Nan Li | 2020 | China Communications2020，17，9： | 37 |
| 2 | Eco-toxicity of petroleum hydrocarbon contaminated soil显示文摘Total petroleum hydrocarbons (TPH) contaminated soil samples were collected from Shengli Oilfield of China. Toxicity analysis was carried out based on earthworm acute toxicity, plant growth experiment and luminescent bacteria test. The soil was contaminated by-petroleum hydrogcarbons with TPH concentration of 10.57%. With lethal and sub-lethal rate as endpoint, earthworm test showed that the LD 50 (lethal dose 50%) values in 4 and 7 days were 1.45% and 1.37% respectively, and the inhibition rate of earthworm body weight increased with higher oil concentration. TPH pollution in the soil inhibited seed germination in both wheat and maize experiment when the concentration of petroleum was higher than 0.1%. The EC 50 (effective concentration 50%) for germination is 3.04% and 2.86% in maize and wheat, respectively. While lower value of EC 50 for root elongation was to be 1.11% and 1.64% in maize and wheat, respectively, suggesting higher sensitivity of root elongation on petroleum contamination in the soil. The EC 50 value in luminescent bacteria test was 0.47% for petroleum in the contaminated soil. From the experiment result, it was concluded that TPH content of 1.5% is considered to be a critical value for plant growth and living of earthworm and 0.5% will affect the activity of luminescent bacteria. | Jingchun Tang Min Wang Fei Wang Qing Sun Qixing Zhou | 2011 | Journal of Environmental Sciences2011，23，5： | 26 |

| 5 | Channel Measurement and Path Loss Modeling from 220 GHz to 330 GHz for 6G Wireless Communications显示文摘Terahertz(THz)communication has been envisioned as a key enabling technology for sixthgeneration(6G).In this paper,we present an extensive THz channel measurement campaign for 6G wireless communications from 220 GHz to 330 GHz.Furthermore,the path loss is analyzed and modeled by using two single-frequency path loss models and a multiplefrequencies path loss model.It is found that at most frequency points,the measured path loss is larger than that in the free space.But at around 310 GHz,the propagation attenuation is relatively weaker compared to that in the free space.Also,the frequency dependence of path loss is observed and the frequency exponent of the multiple-frequencies path loss model is 2.1.Moreover,the cellular performance of THz communication systems is investigated by using the obtained path loss model.Simulation results indicate that the current inter-site distance(ISD)for the indoor scenario is too small for THz communications.Furthermore,the tremendous capacity gain can be obtained by using THz bands compared to using microwave bands and millimeter wave bands.Generally,this work can give an insight into the design and optimization of THz communication systems for 6G. | Pan Tang Jianhua Zhang Haoyu Tian Zhaowei Chang Jun Men Yuxiang Zhang Lei Tian Liang Xia Qixing Wang Jingsuo He | 2021 | China Communications2021，18，5： | 7 |
| 6 | A Predictive 6G Network with Environment Sensing Enhancement:From Radio Wave Propagation Perspective显示文摘In order to support the future digital society,sixth generation(6G)network faces the challenge to work efficiently and flexibly in a wider range of scenarios.The traditional way of system design is to sequentially get the electromagnetic wave propagation model of typical scenarios firstly and then do the network design by simulation offline,which obviously leads to a 6G network lacking of adaptation to dynamic environments.Recently,with the aid of sensing enhancement,more environment information can be obtained.Based on this,from radio wave propagation perspective,we propose a predictive 6G network with environment sensing enhancement,the electromagnetic wave propagation characteristics prediction enabled network(EWave Net),to further release the potential of 6G.To this end,a prediction plane is created to sense,predict and utilize the physical environment information in EWave Net to realize the electromagnetic wave propagation characteristics prediction timely.A two-level closed feedback workflow is also designed to enhance the sensing and prediction ability for EWave Net.Several promising application cases of EWave Net are analyzed and the open issues to achieve this goal are addressed finally. | Gaofeng Nie Jianhua Zhang Yuxiang Zhang Li Yu Zhen Zhang Yutong Sun Lei Tian Qixing Wang Liang Xia | 2022 | China Communications2022，19，6： | 4 |
| 7 | Toxic effects of crude-oil-contaminated soil in aquatic environment on Carassius auratus and their hepatic antioxidant defense system显示文摘Under the indoor simulant conditions, toxic effects of crude-oil-contaminated soil which was put into aquatic environment on the young fishes Carassius auratus and their hepatic antioxidant system after a 20-d exposure were investigated. Results showed that the relationship between the mortality of C. auratus and the exposed doses could be divided into 3 phases: fishes exposed to the low dose groups (0.5-5.0 g/L) were dead due to the ingestion of crude-oil-contaminated soils in aquatic environment; at the medium dose groups (5.0-25.0 g/L) fishes were dead due to the penetration of toxic substances; at the high dose groups (25.0-50.0 g/L) fishes were dead due to environmental stress. The highest mortality and death speed were found in the 1.0 g/L dose group, and the death speed was sharply increased in the 50.0 g/L dose group in the late phase of exposure. The activities of superoxide dismutase (SOD), catalase (CAT) and glutathione S-transferase (GST) and the content of malaondialdehyde (MDA) in the hepatic tissues of C. auratus were induced significantly. The activity of SOD was increased and then decreased. It was significantly inhibited in the 50.0 g/L dose group. The activity of CAT was highly induced, and restored to a level which is little more than the control when the exposed doses exceeded 10.0 g/L. The activity of GST was the most sensitive, it was significantly induced in all dose groups, and the highest elevation was up to 6 times in the 0.5 g/L dose group comparing with the control. The MDA content was significantly elevated in the 50.0 g/L dose group, and the changes of the MDA content were opposite with the changes of GST activity. | WANG Yuanyuan ZHOU Qixing PENG Shengwei MA Lena Q NIU Xiaowei | 2009 | Journal of Environmental Sciences2009，21，5： | 3 |

| 11 | 5G Features from Operation Perspective and Fundamental Performance Validation by Field Trial显示文摘The fast deployment and penetration of 4 G has cultivated human behaviors on mobile data consumption, leading to explosive growth in mobile traffic and stimulating new requirements on the capabilities of mobile networks. To meet the requirements of mobile networks toward year 2020, the next generation of mobile networks(termed as IMT-2020, or 5 G) is designed to support 100 Mbps–1 Gbps user-experienced data rate, 1 ms radio transmission latency, and 1 million connections per square kilometer. Recalling the vision and requirements of 5 G targeting for commercial launch in 2020, this article overviews the key features of 5 G and compares with those of 4 G, and reports the world first field trials conducted to validate the key performance of 5 G radio interface in 3.5 GHz band. The trial results show that a 1 ms transmission latency and 1 Gbps data rate are achievable. | Guangyi Liu Yuhong Huang Fei Wang Jianjun Liu Qixing Wang | 2018 | China Communications2018，15，11： | 2 |
| 12 | Ecotoxicological effects of polycyclic musks and cadmium on seed germination and seedling growth of wheat(Triticum aestivum)显示文摘Single and joint toxic effects of polycyclic musks including 1,3,4,6,7,8-hexahydro-4,6,6,7,8,8-hexamethylcyclopenta[g]-2benzopyran (HHCB) and 7-acetyl-1,1,3,4,4,6-hexamethyl-1,2,3,4-tetrahydronapthalene (AHTN) and cadmium (Cd) on seed germination and seedling growth of wheat (Triticum aestivum) were investigated.The results showed that the toxicity sequence of HHCB toxic to wheat seed germination and seedling growth was similar to that of AHTN,that is,germination rate > shoot elongation > root elongation,while the toxicity of Cd was in the sequence of root elongation > shoot elongation > germination rate,according to the LC50 and EC50 values.It is suggested that polycyclic musks and Cd had different toxicological mechanisms.Root and shoot elongation of wheat might be good bioindicators for the contamination of polycyclic musks and Cd in soil.The mixture of polycyclic musks and Cd had synergistic effects on T.aestivum according to the equi-toxic mixture approach when root elongation was selected as the toxicological endpoint.Thus,the joint toxicity of HHCB and Cd was significantly higher than the single toxicity of HHCB or Cd,which was also confirmed by the EC50 mix value of the mixture (EC50 mix=0.530 TU mix).The EC50 mix value of the mixture of AHTN and Cd was 0.614 TU mix,which indicated that the mixture toxicity was strengthened when AHTN coexisted with Cd. | Cuihong Chen Qixing Zhou Yanyu Bao Yaning Li Ping Wang | 2010 | Journal of Environmental Sciences2010，22，12： | 2 |
| 13 | Effect of graphitic carbon nitride powders on adsorption removal of antibiotic resistance genes from water显示文摘There is a growing need to eliminate antibiotic resistance genes(ARGs)in the environment and mitigate widespread antibiotic resistance.Graphitic carbon nitride(g-C_(3)N_(4))was successfully synthesized via facile thermal polymerization approach and its pote ntial for adsorption treatment of ARGs in water was examined.Batch adsorption experimental results revealed that g-C_(3)N_(4) powders had robust adsorption activity for the gene ampC and ermB.Adsorption kinetics and isotherms were syste matically investigated to explain the adsorption mechanism.The apparent adsorption equilibrium could be reached within180 min.The adsorption process effectively re moved ARGs(ampC and ermB)from water with 3.2 log and4.2 log reductions,respectively.In addition,experimental data were analyzed by several models and simulated well with Langmuir isotherm and pseudo-second-order model.It indicated that adsorption process might be dominated by the chemical rate-limiting step.Moreover,the effects of temperature and pH on the re moval of ARGs were conducted and the isoelectric point(IEP)was obtained.Finally,we have demonstrated that the g-C_(3)N_(4) is a novel adsorbent and can be used as column packing to remove ARGs by filtration. | Haiyin Zhan Yutong Wang Xueyue Mi Zhiruo Zhou Pengfei Wang Qixing Zhou | 2020 | Chinese Chemical Letters2020，31，10： | 2 |

| 15 | Environment Information-Based Channel Prediction Method Assisted by Graph Neural Network显示文摘Recently,whether the channel prediction can be achieved in diverse communication scenarios by directly utilizing the environment information gained lots of attention due to the environment impacting the propagation characteristics of the wireless channel.This paper presents an environment information-based channel prediction(EICP)method for connecting the environment with the channel assisted by the graph neural networks(GNN).Firstly,the effective scatterers(ESs)producing paths and the primary scatterers(PSs)generating single propagation paths are detected by building the scatterercentered communication environment graphs(SCCEGs),which can simultaneously preserve the structure information and highlight the pending scatterer.The GNN-based classification model is implemented to distinguish ESs and PSs from other scatterers.Secondly,large-scale parameters(LSP)and small-scale parameters(SSP)are predicted by employing the GNNs with multi-target architecture and the graphs of detected ESs and PSs.Simulation results show that the average normalized mean squared error(NMSE)of LSP and SSP predictions are 0.12 and 0.008,which outperforms the methods of linear data learning. | Yutong Sun Jianhua Zhang Yuxiang Zhang Li Yu Qixing Wang Guangyi Liu | 2022 | China Communications2022，19，11： | 1 |
