One of the key technologies supported by NR is ultra-reliable and low latency communications (URLLC), aiming at meeting extremely stringent requirements: data error rate of below 10−5 and layer 2 latency of below 1 ms. One of the typical use cases of URLLC is Internet of Things (IoT) e.g. factory automation. Considering the fact that Wireless LAN (WLAN) systems are already widely deployed for IoT industrial applications, the IoT system can make full use of WLAN for supporting URLLC. Therefore, system architectures should be investigated in which NR technology can be integrated into the WLAN system which is already deployed for IoT industrial applications. In this paper, three architectures are proposed. Among them, it is found that architectures with novel feature “bearer aggregation” provides better support of URLLC. One open question is discussed, and it is shown that an enhanced WLAN system which is developed by the authors can potentially address the question.","PeriodicalId":348099,"journal":{"name":"2020 IEEE 91st Vehicular Technology Conference (VTC2020-Spring)","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116067633","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}

Vehicular communications for platooning are considered to be one of new use cases of 5G whose low-latency and ultra-reliability are required. This paper presents our field experimental evaluation on latency and reliability performance of 5G NR V2V Direct communication towards application to truck platooning. The authors built a field experimental environment, for V2X communications of truck platooning, with actual large-size trucks and a prototype system employing 5G New Radio (NR) technologies, and performed some field experiments in rural areas. In this paper, we introduce the 5G NR-V2X prototype system. It is most distinctive that the prototype system is equipped with V2V Direct communication radio interface (i.e., sidelink), in addition to the traditional radio interfaces between BS and UE (i.e., downlink and uplink). Then, we present the evaluation results on over-the-air latency and reliability performance on the V2V Direct communication of the prototype in real express highway environment to assess 5G NR-V2X system applying to truck platooning. The evaluation results demonstrate that our developed 5G NR-V2X prototype system simultaneously achieves the peak performance with the low latency of below 1ms and the high reliability of above 99.999% in a real express highway environment.","PeriodicalId":348099,"journal":{"name":"2020 IEEE 91st Vehicular Technology Conference (VTC2020-Spring)","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122309903","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 metallic chassis and the energysaving coating on the windows act as a radio shield. In combination with sparsely spaced cellular base stations on rural routes, the coverage onboard inter-city trains is under dimensioned. Since the late 1990s, analog “amplify and forward” radio repeaters have been used extensively to provide coverage of cellular voice onboard trains. However, repeater systems have proven to be both expensive and technically problematic for both trains as well as mobile network operators. In this study, three alternative technologies for providing cellular voice onboard trains are investigated and benchmarked. The technologies under investigation are: circuit-switched voice on GSM and 3G; Voice over IP on LTE (VoLTE); Voice over the onboard Wi-Fi network (VoWiFi). To benchmark these systems against each other, measurements were conducted onboard Swedish X2000 trains, en-route between Stockholm and Gothenburg. In particular we measure: the Availability; the Retainability: Geographical Coverage and Voice quality. Our results show that VoWiFi over the onboard Wi-Fi network outperforms GSM, UMTS as well as VoLTE provided over the onboard repeaters, with equal voice quality as VoLTE but nearly 100% availability and nearly 100% retainability.","PeriodicalId":348099,"journal":{"name":"2020 IEEE 91st Vehicular Technology Conference (VTC2020-Spring)","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122435283","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}

Motivated by the richer representational capacity of complex numbers and the fact that communication is a complex-valued problem, a novel clipping noise estimation scheme based on deep complex neural network is proposed in this paper. Specifically, the clipping noise is determined by a deep complex network, namely clipping noise estimation network (CNE-Net), such that the mean square error (MSE) and the sparsity of the estimated clipping noise are jointly optimized. Besides, an ordering based zero-forcing scheme is utilized to further ensure the sparsity of the estimated clipping noise. Simulation results show that the proposed CNE-Net shows comparable performance with the conventional decision-aided reconstruction (DAR) scheme and can achieve better performance than the one-iteration DAR scheme when the clipping noise is not sparse enough. In summary, the CNE-Net has a good capability to estimate the clipping noise from noise-affected features.","PeriodicalId":348099,"journal":{"name":"2020 IEEE 91st Vehicular Technology Conference (VTC2020-Spring)","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114251678","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}

One of the techniques to provide the required coverage is to employ a node deployment algorithm to accurately locate all sensor nodes in the RoI to obtain the maximum coverage. Distributed node deployment algorithms in Mobile Sensor Networks (MSNs) are of more interest as all nodes have to cooperatively move to a position to provide overall optimal coverage. The final coverage offered by most of the algorithms reported in the literature is highly dependent on the initial coverage after the initial deployment. In this paper, the Voronoi-based Cooperative Node Deployment (VCOND) algorithm is proposed to efficiently provide the maximum coverage regardless of the initial locations of sensor nodes. Despite other algorithms which terminate the movement of each node solely based on the status of the current node and neglect the neighbourhood circumstances, the knowledge of the node one-hop vicinity is reflected on VCOND decision using two criteria: density of neighbourhood and sensing coverage efficiency. This effectively alleviates the dependency of the algorithm to the initial deployment of sensors while providing the maximum coverage. Our extensive simulation study shows not only a higher percentage of area coverage by VCOND but with less dependency on the initial deployment of sensors.","PeriodicalId":348099,"journal":{"name":"2020 IEEE 91st Vehicular Technology Conference (VTC2020-Spring)","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122129189","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}
