We model and calculate the interference power at victim receivers referring to up-to-date ITU-R documents and compare them with the protection criteria of the victim receivers. Furthermore, three-dimensional (3D) topographic data with latitude/longitude/altitude coordinates are adopted to exactly model the interference power aggregated from a large number of terrestrial IMT-2020 systems in worldwide areas. The results show that the FSS space station is safe from the aggregated IMT-2020 interference, and the IMT-2020 service can be protected when base station (BS) and user equipment (UE) are located 3.3 and 0.9 km away from the FSS earth station.","PeriodicalId":417962,"journal":{"name":"2018 International Conference on Information and Communication Technology Convergence (ICTC)","volume":"69 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124130382","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The receiver is supposed to have some fixed size of buffers (called resequecing buffer) which are used to temporarily store the packets that are correctly received out of sequence. The hybrid ARQ scheme is a combination of Go-Back-N ARQ and Selective-Repeat ARQ protocols. The system operates under the SR-ARQ protocol while there are still some available buffers for the upcoming packets at the receiver. Reversely, the system operates under the Go-Back-N ARQ protocol when the resequencing buffers are totally occupied by the packets which are received out of sequence. We describe the detailed operations of the presented hybrid ARQ scheme and evaluate the system performance (mainly throughput efficiency) under the assumption that the system has two or three different channels. We show the influences of various features on the throughput efficiency and illustrate it at different conditions, such as the number of channels, delay of channels etc. Based on the results of computer simulation, it is clear that throughput efficiency would be reduced by unduly using multiple channels at certain conditions, and introducing buffers at receiver is extremely efficacious as the way to deal with the problem.","PeriodicalId":417962,"journal":{"name":"2018 International Conference on Information and Communication Technology Convergence (ICTC)","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130972234","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This led to a direct increase in operating costs in terms of mobile telecommunication service providers. In this process, the operation method that minimizes the power consumption of the mobile network equipment while keeping the user’s service experience at the highest level is examined, and the PSi & PSo algorithm that can realize this is discovered and verified in the commercial network. With this, it will be possible to meet both the power saving and the service experience when it is adjusted according to the traffic level.

Among these technologies, drones can be useful to generate high-resolution 3D urban models to provide detailed information about the smart city structure. However, successfully using drones for 3D modeling of wide areas is challenging mainly because of their limited resources such as battery autonomy, onboard memory, and processing. Therefore, trajectory planning can improve resource utilization by reducing the search space during drone flight for modeling. We propose a comprehensive framework based on the geographic information system for drone trajectory planning. Compared to previous studies, we simultaneously apply trajectory and 3D modeling constraints using flight map information including visibility, wind and risk. We verify the effectiveness of the proposed approach on datasets from the South Korea Open Data.","PeriodicalId":417962,"journal":{"name":"2018 International Conference on Information and Communication Technology Convergence (ICTC)","volume":"10 3","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131672150","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
